Understanding the different types of scopes in JavaScript is crucial for writing efficient and error-free code. Here are the primary types of scopes in JavaScript:
1. **Global Scope**
Definition: Variables declared outside any function or block have global scope, meaning they are accessible from anywhere in the code.
Creation: Variables become global if they are declared with var outside any function or if they are not declared with let, const, or var inside a function (implicitly global).
`var globalVar = 'I am a global variable';
function displayGlobalVar() {
console.log(globalVar); // Accessible here
}
displayGlobalVar();
console.log(globalVar); // Accessible here too
`
2. **Local Scope (Function Scope)**
Definition: Variables declared within a function are in the local scope (or function scope). They are only accessible within that function.
Creation: Any variable declared inside a function using var, let, or const.
`function myFunction() {
var localVar = 'I am a local variable';
console.log(localVar); // Accessible here
}
myFunction();
console.log(localVar); // Uncaught ReferenceError: localVar is not defined
`
3. **Block Scope**
Definition: Variables declared within a block (denoted by {}) are only accessible within that block. This type of scope was introduced with ES6 and applies to variables declared using let and const.
Creation: Any variable declared inside a block using let or const.
`{
let blockVar = 'I am a block-scoped variable';
const blockConst = 'I am also block-scoped';
console.log(blockVar); // Accessible here
console.log(blockConst); // Accessible here
}
console.log(blockVar); // Uncaught ReferenceError: blockVar is not defined
console.log(blockConst); // Uncaught ReferenceError: blockConst is not defined
`
4. **Lexical Scope (Static Scope)**
Definition: Lexical scope means that the accessibility of variables is determined by their physical location in the code at the time of writing. Inner functions have access to variables defined in outer functions.
Creation: Automatically created based on where functions are declared.
`function outerFunction() {
var outerVar = 'I am an outer variable';
function innerFunction() {
console.log(outerVar); // Accessible due to lexical scope
}
innerFunction();
}
outerFunction();
`
5. **Module Scope**
Definition: Variables declared within a module (using the ES6 module system) are scoped to that module. They are not accessible outside the module unless explicitly exported.
Creation: Using import and export statements in ES6 modules.
`// module1.js
export const moduleVar = 'I am a module-scoped variable';
// main.js
import { moduleVar } from './module1.js';
console.log(moduleVar); // Accessible here
`
**Scope Chain**
The scope chain is a hierarchical structure that determines the order in which scopes are looked up to resolve variable names. When a variable is referenced, JavaScript starts looking in the current scope, then moves up to the outer scope, and continues this process until it reaches the global scope.
`var globalVar = 'I am global';
function outerFunction() {
var outerVar = 'I am outer';
function innerFunction() {
var innerVar = 'I am inner';
console.log(innerVar); // Found in inner scope
console.log(outerVar); // Found in outer scope
console.log(globalVar); // Found in global scope
}
innerFunction();
}
outerFunction();
`
**Closures**
Closures are functions that remember their lexical scope even when they are executed outside of that scope. This allows inner functions to access variables from their outer function scope even after the outer function has returned.
`function outerFunction() {
var outerVar = 'I am outer';
function innerFunction() {
console.log(outerVar);
}
return innerFunction;
}
const closureFunction = outerFunction();
closureFunction(); // 'I am outer' - outerVar is still accessible
`
**Summary**
Understanding these different types of scopes and their behavior is essential for managing variable accessibility and preventing issues like variable shadowing and unintentional global variable creation. It also helps in writing clean, maintainable, and error-free JavaScript code. | kiransm |
1,889,403 | Spring AI, Llama 3 and pgvector: bRAGging rights! | In the very beginning at least, Python reigned supreme in terms of tooling for AI development.... | 0 | 2024-06-15T14:35:35 | https://dev.to/mcadariu/springai-llama3-and-pgvector-bragging-rights-2n8o | In the very beginning at least, Python reigned supreme in terms of tooling for AI development. However, recently came the answer from the Spring community, and it's called [Spring AI](https://spring.io/projects/spring-ai)! This means that if you're a Spring developer with working knowledge of concepts such as beans, auto-configurations and starters, you're covered, and you can write your AI apps following the standard patterns you're already familiar with.
In this post, I want to share with you an exploration that started with the goal to take Spring AI for a little spin and try out the capabilities of open-source LLMs (large language models). I got curious along the way, and ended up also looking at some pretty low-level details about data storage for AI applications as well.
To support the exploration, I've developed a simple [Retrieval Augmented Generation (RAG)](https://www.promptingguide.ai/techniques/rag) workflow that works completely locally on the laptop for free. If you're interested, you can find the code itself [here](https://github.com/mcadariu/spring-ai-rag-demo/blob/main/src/test/java/com/example/braggingrights/demo/RAGDemoApplicationTests.java). Basically, I've used [`Testcontainers`](https://testcontainers.com/) to create a Postgres database container with the [pgvector](https://github.com/pgvector/pgvector) extension to store text [embeddings](https://vickiboykis.com/what_are_embeddings/) and an open source LLM with which I send requests to: Meta's [`llama3`] (https://ai.meta.com/blog/meta-llama-3/) (8B) through [`ollama`](https://ollama.com/).
Alright, let's have a look at what I'm building with this setup.
## Fun with sayings and essays
The RAG workflow works like this. I first ask it to generate a couple of **sayings**, for example this is one among the ones I got back:
>
A bad excuse is better than none.
Then, I ask it to "elaborate" and genarate an **essay** (of under 200 words) about the saying it provided me earlier. Here is one such essay generated by `llama3` for the saying above:
>
The saying suggests that while an inadequate justification may not be satisfactory, it's still preferable to having no explanation at all. This phrase highlights the importance of accountability and acknowledging responsibility for one's actions or decisions.
>
In essence, a bad excuse implies that some effort has been made to justify or rationalize one's behavior, even if the reasoning is flawed or unconvincing. On the other hand, not offering any excuse whatsoever can come across as evasive or dishonest, leading to mistrust and resentment.
>
This saying encourages people to take ownership of their mistakes and apologize for any wrongdoing, rather than remaining silent and avoiding accountability. It also acknowledges that everyone makes errors and that a bad excuse is better than none because it shows a willingness to acknowledge and learn from those mistakes.
>
Ultimately, the saying promotes honesty, responsibility, and personal growth by emphasizing the value of taking ownership of one's actions, no matter how imperfect the explanation may be.
Then, I will take these essays and create [embeddings](https://vickiboykis.com/what_are_embeddings/) from them, which I will store in Postgres, using the `pgvector` extension in columns of `vector` data type. All with the help of Spring AI abstractions and least amount of custom code.
I will skip the part of this process called "chunking". When you are dealing with very large documents, or want to isolate sections in your data (like in e-mails where you have subject, sender, etc..) you might look into doing that.
So far so good. At this point, we have stored the data we need in the next steps.
I will then take each saying and do a **similarity search** on the embeddings to retrieve the corresponding essay for each saying. Lastly, I will supply the retrieved essays back again to the LLM, and now ask it to **guess the original saying** from which the essay was generated. Finally I will check how many it got right.
What do you think, will it manage to correctly guess the saying from just the essay? After all, it has generated the essays from those sayings itself in the first place. A human would have no problem doing this.
But let's first have a look at how the program is set up from a technical perspective. We will look at the results and find out how capable is the LLM a bit later.
## The LLM and the vector store in Testcontainers
`Testcontainers` makes it very easy to integrate services that each play a specific role for use-cases like this. All that is required to set up a database and the LLM are the couple of lines below and you're good to go!
```java
@TestConfiguration(proxyBeanMethods = false)
class RagDemoApplicationConfiguration {
private static final String POSTGRES = "postgres";
@Bean
@ServiceConnection
PostgreSQLContainer<?> postgreSQLContainer() {
return new PostgreSQLContainer<>("pgvector/pgvector:pg16")
.withUsername(POSTGRES)
.withPassword(POSTGRES)
.withDatabaseName(POSTGRES)
.withInitScript("init-script.sql");
}
}
@Bean
@ServiceConnection
OllamaContainer ollamaContainer() {
return new OllamaContainer("ollama/ollama:latest");
}
}
```
I've used the `@ServiceConnections` annotation that allows me to type [less configuration code](https://spring.io/blog/2023/06/23/improved-testcontainers-support-in-spring-boot-3-1). I can do this for the `ollama` container too only since recently, thanks to this recent [contribution](https://github.com/spring-projects/spring-ai/pull/453) from Eddú Meléndez.
You might have noted there's an init script there. It's only a single line of code, and has the purpose to install a Postgres extension called [pg_buffercache](https://www.postgresql.org/docs/current/pgbuffercache.html) which lets me inspect the contents of the Postgres [shared buffers](https://minervadb.xyz/understanding-shared-buffers-implementation-in-postgresql/) in RAM. I'm interested in having a look at this in order to better understand the operational characteristics of working with vectors. With other words, what are the memory demands?
```sql
create extension pg_buffercache;
```
Now, to fully initialise our LLM container such that it's ready to actually handle our requests for our sayings and essays, we need to pull the models we want to work with, like so:
```java
ollama.execInContainer("ollama", "pull", "llama3");
ollama.execInContainer("ollama", "pull", "nomic-embed-text");
```
You will notice that besides the `llama3` that I mentioned before which will take care of generating text, I am also pulling a so-called embedding model: `nomic-embed-text`. This is to be able to convert text into embeddings, to be able store them.
The ones I'm using are not the only options. New LLM bindings and embedding models are added all the time in both Spring AI and ollama, so refer to the [docs](https://spring.io/projects/spring-ai) for the up-to-date list, as well as the [ollama](https://ollama.com/) website.
## Configuration properties
Let's have a look at the vector store configuration. Here's how that looks:
```java
@DynamicPropertySource
static void pgVectorProperties(DynamicPropertyRegistry registry) {
registry.add("spring.ai.vectorstore.pgvector.index-type", () -> "HNSW");
registry.add("spring.ai.vectorstore.pgvector.distance-type", () -> "COSINE_DISTANCE");
registry.add("spring.ai.vectorstore.pgvector.dimensions", () -> 768);
}
```
The first one is called `index-type`. This means that we are creating an index in our vector store. We don't necessarily need to always use an index - it's a trade-off. With indexing, the idea is that we gain speed (and other things, like uniqueness, etc) at the expense of storage space. With indexing vectors however, the trade-off also includes the **relevance** aspect. Without indexing, the similarity search is based on the kNN algorithm (k-nearest neigbours) where it checks all vectors in the table. However with indexing, it will perform an aNN (_approximate_ nearest neighbours) which is faster but might miss some results. Indeed, it's quite the balancing act.
Let's have a look at the other configuration options for indexing, which I extracted from the Spring AI code:
```java
NONE,
IVFFLAT,
HNSW;
```
In the beginning, there used to be only one option for indexing in pgvector, namely `ivfflat`. More recently, the `HNSW` (Hierarchical Navigable Small Worlds) one was added, which is based on different construction principles and is more performant, and keeps getting better. The general recommendation is to go for `HNSW` as of now.
The next configuration option is the `distance-type` which is the procedure it uses to compare vectors in order to determine similarity. Here are our options:
```java
EUCLIDEAN_DISTANCE,
NEGATIVE_INNER_PRODUCT,
COSINE_DISTANCE;
```
I'll go with the cosine distance, but it might be helpful to have a look at their [properties](https://cmry.github.io/notes/euclidean-v-cosine) because it might make a difference for your use-case.
The last configuration property is called `dimensions`, which represent the number of components (tokenized float values) that the embeddings will be represented on. This number has to be correlated with the number of dimensions we set up in our vector store. In our example, the `nomic-embedding-text` one has 768, but others have more, or less. If the model returns the embeddings in more dimensions than we have set up our table, it won't work. Now you might wonder, should you strive to have as high number of dimensions as possible? Actually the answer to this question is apparently no, this blog from Supabase shows that [fewer dimensions are better](https://supabase.com/blog/fewer-dimensions-are-better-pgvector).
## Under the hood - what's created in Postgres?
Let's explore what Spring AI has created for us with this configuration in Postgres. In a production application however, you might want to take full control and drive the schema through SQL files managed by migration tools such as Flyway. We didn't do this here for simplicity.
Firstly, we find it created a table called `vector_store` with the following structure:
```sql
postgres=# \d vector_store;
Table "public.vector_store"
Column | Type | Collation | Nullable | Default
-----------+-------------+-----------+----------+--------------------
id | uuid | | not null | uuid_generate_v4()
content | text | | |
metadata | json | | |
embedding | vector(768) | | |
Indexes:
"vector_store_pkey" PRIMARY KEY, btree (id)
"spring_ai_vector_index" hnsw (embedding vector_cosine_ops)
```
Nothing surprising here. It's in-line with the configuration we saw above in the Java code I showed you earlier. For example, we notice the `embedding` column of type `vector`, of 768 dimensions. We notice also the index - `spring_ai_vector_index` and the `vector_cosine_ops` operator class, which we expected given what we set in the "distance-type" setting earlier. The other index, namely `vector_store_pkey`, is created automatically by Postgres. It creates such an index for every primary key by itself.
The command that Spring AI used to create our index is the following:
```sql
CREATE INDEX IF NOT EXISTS %s ON %s USING %s (embedding %s)
```
This creates an index with the default configuration. It might be good to know that you have a couple of [options](https://github.com/pgvector/pgvector?tab=readme-ov-file#index-options) if you'd like to tweak the index configuration for potentially better results (depends on use-case):
* _m_ - the max number of connections per layer
* _ef_construction_ - the size of the dynamic candidate list for constructing the graph
Theres are the boundaries you can pick from for these settings:
| Setting | default | min | max |
| -------- | ------- | ------ | ------ |
| *m* | 16 | 2 | 100 |
| *ef_construction* | 64 | 4 | 1000 |
In order to understand the internals of this index and what effect changing the above options might have, here is a [link to the original paper](https://arxiv.org/pdf/1603.09320). See also this [post](https://jkatz05.com/post/postgres/pgvector-hnsw-performance/) by J. Katz in which he presents results of experimenting with various combinations of the above settings.
When you know what values you want to set for these settings you can create the index like so:
```sql
CREATE INDEX ON vector_store
USING hnsw (embedding vector_cosine_ops)
WITH (m = 42, ef_construction = 42);
```
In case you get an error when constructing an index, it's worth looking into if it has enough memory to perform this operation. You can adjust the memory for it through the `maintenance_work_mem` setting.
Let's now check how our `embedding` column is actually stored on disk. We use the following [query](https://stackoverflow.com/a/49947950) which will show us our next step.
```sql
postgres=# select
att.attname,
case
att.attstorage
when 'p' then 'plain'
when 'm' then 'main'
when 'e' then 'external'
when 'x' then 'extended'
end as attstorage
from
pg_attribute att
join
pg_class tbl on tbl.oid = att.attrelid
join
pg_namespace ns on tbl.relnamespace = ns.oid
where
tbl.relname = 'vector_store' and
ns.nspname = 'public' and
att.attname = 'embedding';
```
Result:
```sql
-[ RECORD 1 ]---------
attname | embedding
attstorage | external
```
Alright, so it uses the `external` storage type. This means that it will store this column in a separate, so-called [TOAST](https://www.postgresql.org/docs/current/storage-toast.html) table. Postgres does this when columns are so large it can't fit at least 4 rows in a [page](https://www.postgresql.org/docs/16/storage-page-layout.html). But interesting that it will _not_ attempt to also compress it to shrink it even more. For compressed columns it would have said `extended` instead of `external` in the result above.
Normally, when you update one or multiple columns of a row, Postgres will, instead of overwriting, make a copy of the entire row (it's an [MVCC](https://www.postgresql.org/docs/current/mvcc-intro.html) database). But if there are any large TOASTed columns, then during an update it will copy only the other columns. It will copy the TOASTed column only when that is updated. This makes it more efficient by minimising the amount of copying around of large values.
Where are these separate tables though? We haven't created them ourselves, they are managed by Postgres. Let's try to locate this separate TOAST table using this [query](https://medium.com/quadcode-life/toast-tables-in-postgresql-99e3403ed29b):
```sql
postgres=# select
relname,
oid
from
pg_class,
(select
reltoastrelid
from
pg_class
where
relname = 'vector_store') as vector_store
where
oid = vector_store.reltoastrelid or
oid = (select
indexrelid
from
pg_index
where
indrelid = vector_store.reltoastrelid
);
```
```sql
relname | oid
----------------------+-------
pg_toast_16630 | 16634
pg_toast_16630_index | 16635
```
So far so good. We now have the TOAST table ID. Let's use it to have a look at the structure of the TOAST table. For example, what columns does it have? Note that these tables are in the `pg_toast` schema, by the way, so to get there, we have to set the `search_path` to `pg_toast`, like below:
```sql
postgres=# set search_path to pg_toast;
SET
postgres=# \d pg_toast_16630;
TOAST table "pg_toast.pg_toast_16630"
Column | Type
------------+---------
chunk_id | oid
chunk_seq | integer
chunk_data | bytea
Owning table: "public.vector_store"
Indexes:
"pg_toast_16630_index" PRIMARY KEY, btree (chunk_id, chunk_seq)
```
We can learn a couple of things from this. As expected, the large columns in the main table that have to be "TOASTed" are chunked (split up) and each chunk is identified by a sequence, and is always retrieved using an index.
Postgres has a mechanism to avoid "blasting" the entire shared buffer cache when it needs to do large reads, like sequential scans of a large table. When it has to do this, it actually uses a 32 page ring buffer so that it doesn't evict other data from the cache. But this mechanism will not kick in for TOAST tables, so vector-based workloads will be run without this form of protection.
Okay! We had a very good look at the database part. Let's now "resurface" for a moment and have a look at other topics pertaining to the high level workflow of interacting with the LLM.
## Template-based prompts
Initially, I had constructed the prompts for the request to the LLM in the same class where I was using them. However, I found the following different approach in the Spring AI repository itself and adopted it, because it's indeed cleaner to do it this way. It's based on externalised resource files, like so:
```java
@Value("classpath:/generate-essay.st")
protected Resource generateEssay;
@Value("classpath:/generate-saying.st")
protected Resource generateSaying;
@Value("classpath:/guess-saying.st")
protected Resource guessSaying;
```
This is how one of them looks inside.
```
Write a short essay under 200 words explaining the
meaning of the following saying: {saying}.
```
As you can see, I have not applied any sophisticated [prompt engineering](https://www.promptingguide.ai/) whatsoever, and kept it simple and direct for now.
## Calling the LLM
Alright, the pieces are starting to fit together! The next thing I'd like to show you is how to call the LLM.
```java
chatModel
.withModel(model)
.call(createPromptFrom(promptTemplate, promptTemplateValues))
.getResult()
.getOutput()
.getContent();
```
I am using the so-called [`Chat Model API`](https://docs.spring.io/spring-ai/reference/api/chatmodel.html), a powerful abstraction over AI models. This design allows us to switch between models with minimal code changes. If you want to work with a different model, you just change the runtime configuration. This is a nice example of the Dependency Inversion Principle; where we have higher level modules that do not depend on low-level modules, both depend on abstractions.
## Storing the embeddings
To store the embeddings, I must say that I found it a pretty complicated procedure:
```java
vectorStore.add(documents);
```
Just kidding, that's it!
This single command will do several things. First convert the documents (our essays) to embeddings with the help of the embeddings model, then it will run the following batched insert statement to get the embeddings into our `vector_store` table:
```sql
INSERT INTO vector_store (id, content, metadata, embedding) VALUES (?, ?, ?::jsonb, ?) ON CONFLICT (id) DO UPDATE SET content = ? , metadata = ?::jsonb , embedding = ?
```
We can see it actually performs an update of the `content` column in case there is already one row with that ID (taken care of by the `ON CONFLICT` part in the query) present in the database.
## Similarity searches
To do a similarity search on the stored vectors with Spring AI, it's just a matter of:
```java
vectorStore
.similaritySearch(SearchRequest.query(saying))
.getFirst()
.getContent();
```
Again you get a couple of things done for you by Spring AI. It takes the parameter you supply ("saying" in our case), and first it creates its embedding using the embedding model we talked about before. Then it uses it to retrieve the most similar results, from which we pick only the first one.
With this configuration (cosine similarity), the SQL query that it will run for you is the following:
```sql
SELECT *, embedding <=> ? AS distance FROM vector_store WHERE embedding <=> ? < ? AND metadata::jsonb @@ <nativeFilterExpression>::jsonpath ORDER BY distance LIMIT ?
```
It selects all the columns in the table and adds a column with the calculated distance. The results are ordered by this distance column, and you can also specify a similarity threshold and a native filter expression using Postgres' jsonpath functionality.
One thing to be noted, is that if you'd write the query yourself and run it with without letting Spring AI create it for you, you can [customise](https://github.com/pgvector/pgvector?tab=readme-ov-file#query-options) the query by supplying different values for the `ef_search` parameter (default: 40, min: 1, max: 1000), like so:
```sql
SET hnsw.ef_search = 42;
```
With it, you can influence the number of neighbours that it considers for the search. The more that are checked, the better the recall, but it will be at the expense of performance.
Now that we know how to do perform similarity searches to retrieve semantically close data, we can also make a short incursion into how Postgres uses memory (shared buffers) when performing these retrievals.
## How much of the shared buffers got filled up?
Let's now increase a bit the amount of essays we're working with to `100`, and have a look what's in the Postgres shared buffers after we run the program. We'll use the `pg_buffercache` extension that I mentioned before, which was installed in the init script.
But first, let's start with looking at the size of the table and index, just to get some perspective.
```sql
postgres=# \dt+ vector_store;
List of relations
Schema | Name | Type | Owner | Persistence | Access method | Size | Description
--------+--------------+-------+----------+-------------+---------------+--------+-------------
public | vector_store | table | postgres | permanent | heap | 584 kB |
```
```sql
postgres=# \di+ spring_ai_vector_index;
List of relations
Schema | Name | Type | Owner | Table | Persistence | Access method | Size | Description
--------+------------------------+-------+----------+--------------+-------------+---------------+--------+-------------
public | spring_ai_vector_index | index | postgres | vector_store | permanent | hnsw | 408 kB |
(1 row)
```
Okay, so the table is `584 kB` and the index is `408 kB`. It seems the index gets pretty big, close to being about the same size of the table. We don't mind that much at such small scale, but if we assume this proportion will be maintained at large scale too, we will have to take it more seriously.
To contrast with how other indexes behave, I checked a table we have at work that amounts to `40Gb`. The corresponding B-tree primary key index is `10Gb`, while other indexes of the same type for other columns are just `3Gb`.
I'm using the following [query](https://tomasz-gintowt.medium.com/postgresql-extensions-pg-buffercache-b38b0dc08000) to get an overview of what's in the shared buffers:
```sql
select
c.relname,
count(*) as buffers
from
pg_buffercache b
inner join
pg_class c on b.relfilenode = pg_relation_filenode(c.oid) and
b.reldatabase in (0, (select
oid
from
pg_database
where
datname = current_database()
)
)
group by
c.relname
order by
2 desc
limit
10;
```
```sql
relname | buffers
--------------------------------+---------
pg_proc | 61
pg_toast_16630 | 53
spring_ai_vector_index | 51
pg_attribute | 35
pg_proc_proname_args_nsp_index | 30
pg_depend | 23
pg_operator | 19
pg_statistic | 19
pg_class | 18
vector_store | 18
(10 rows)
```
We see that all the index in its entirety is in there. We deduced this because the size of the index is `408 Kb`, as we saw before, and if we divide that by `8 Kb`, which is the size of a Postgres page, we get exactly `51` like we see in the above table (third row above).
We can draw a conclusion from this - working with vectors in Postgres is going to be pretty demanding in terms of memory. As reference, vectors that have 1536 dimensions (probably the most common case) will occupy each about `6Kb`. One million of them already gets us to `6Gb`. In case we have other workloads next to the vectors, they might be affected in the sense that we start seeing cache evictions because there's no free buffer. This means we might even need to consider separating the vectors from the other data we have, in separate databases, in order to isolate the workloads in case we notice the performance going downhill.
## The `@ParameterizedTest` JUnit annotation
Alright, a last remark I want to make about this program is that it's set up to be able to experiment with other open-source LLMs. The entrypoint method I'm using to run the workflow, is a JUnit parameterized test where the arguments for each run can be the names of other LLM models distributed with ollama. This is how you set it up to run multiple times with a different LLM for every execution:
```java
@ParameterizedTest
@ValueSource(strings = {"llama3", "llama2", "gemma", "mistral"})
void rag_workflow(String model) {
...
}
```
## Outputs
Finally it's time to review how well did the LLM manage to guess the sayings. With no other help except for the initial essays provided in the prompt, it managed to guess the saying perfectly a grand total of... once!

Some responses are quite amusing, like when it tries to be "mysterious" or more conversational by not completing the sentence fully and just ending it in three dots ("What doesn't kill you..."), and the ones where it reaches for extreme succintness ("Take the leap.", "Be brave.").
Let's give it some help now. In the prompt, this time I'll provide all the sayings it initially generated as a list of options to pick from. Will it manage to pick the correct one from the bunch this way?
Turns out, indeed, if I gave it options to pick from, it picked the right one, every time. Quite the difference between with or without RAG!
## Conclusion
Spring AI is a well designed application framework that helps you achieve a lot with little code. You can see it as the "linchpin" that helps you set up and easily evolve your AI use-cases in in stand-alone new applications or integrated with your existing Spring ones. It already has many integrations with specialised AI services and the list keeps growing constantly.
The open-source LLMs I tried have not raised to the occasion, and haven't passed my "challenge" to guess the initial sayings they themselves generated from their (also own) essays. They seem not ready to perform well for use-cases that require this kind of precise and correct "synthesised" answers, but I will keep trying new models as they are made available.
However, they are still useful if you know what you can expect from them - they are very good for storing and retrieving many loosely connected facts, a clear value-add when needing to brainstorm for example.
When I gave it the options, the difference is like night and day compared to when I didn't. If given the options, it picked the right answer every time, flawlessly.
We also looked at how embeddings are stored internally with the `pgvector` extension, and how "memory-hungry" this is - we should account for this and make some arrangements at the beginning of the project in order to have smooth operation when the scale grows.
## Next steps
While writing this post, [`pgvectorscale`](https://github.com/timescale/pgvectorscale) got released. It's an interesting new project that makes `pgvector` more performant and cost-effective. I'd like to compare the difference between how fast it is compared with `pgvector` for the sayings and essays use-case I presented above. It should be easy to just switch between the two - everything stays the same, just initialise the database a bit differently in the beginning.
I have made a separate [branch](https://github.com/mcadariu/spring-ai-rag-demo/blob/pgvectorscale/src/test/java/com/example/braggingrights/demo/RagDemoApplicationConfiguration.java) in the same repo where instead of `pgvector` like in the sections above, I'm now trying to start up `pgvectorscale` instead:
```java
@Bean
@ServiceConnection
PostgreSQLContainer<?> postgreSQLContainer() {
return new PostgreSQLContainer<>(DockerImageName
.parse("timescale/timescaledb-ha:pg16-all")
.asCompatibleSubstituteFor("postgres"))
.withUsername(POSTGRES)
.withPassword(POSTGRES)
.withDatabaseName(POSTGRES)
.withInitScript("init-script.sql");
}
```
In the init script, I've added the following, per the [instructions](https://github.com/timescale/pgvectorscale?tab=readme-ov-file#using-a-pre-built-docker-container):
```sql
create extension if not exists vectorscale CASCADE;
```
To be continued!
Thanks for reading!

# The Evolving Developer Experience: A Symphony of Speed, Skill, and Serendipity
## The Tempo of Change
The modern developer experience is like listening to a complex symphony, where creativity is harmoniously composed by skill, speed, and serendipity. On the other hand, the development landscape is changing faster due to the steady stream of new tools and technologies.
This accelerated tempo presents both opportunities and challenges for developers. On the one hand, the emergence of AI-powered tools acts as a great assistant, automating repetitive tasks and orchestrating the development workflow. This increases developer speed, freeing them to focus on problem-solving and pushing the boundaries of innovation.
However, the ever-increasing tempo can become overwhelming. Developers must continuously adapt and learn new skills to stay relevant in this fast-paced environment.
With their intricate systems and constantly growing toolchains, modern development can have a dense and complex underbelly. Because of this intricacy, developers must work together and communicate clearly to ensure everyone is on the same page. Even though AI-powered tools can solve complex portions, human data interpretation and decision-making are still crucial.
## Key Signatures of Collaboration
The way developers work together is undergoing a revolution. Virtual environments are becoming the new workplace, fostering remote teamwork and global collaboration. These evolving dynamics require a fresh approach to collaboration, emphasizing soft skills like active listening, effective communication, and empathy to cultivate a positive and productive team atmosphere.
This shift coincides with the democratization of development, a movement that expands access to software development beyond professional coders. Low-code/no-code platforms empower a wider range of users, including citizen developers and those with limited coding experience, to participate in building applications. This opens doors for more diverse perspectives and fosters innovation, ultimately accelerating digital transformation across industries.
## The Orchestra of Technologies
The software development landscape thrives on collaboration and innovation, and two key players make this harmony possible: open-source communities and cloud computing.
### Open Source Communities
Open source communities function like a symphony orchestra, with a diverse range of developers contributing their talents. Open-source tools and software are freely available, eliminating financial barriers for developers worldwide. This fosters a more inclusive and equitable development environment by democratizing access to technology.
Open source fuels creativity by encouraging experimentation and iteration. Developers can access and modify source code, fostering transparency and trust. This allows for security audits and promotes overall stability within the software ecosystem. Open-source communities are invaluable support systems for developers. Developers can exchange ideas through forums, mailing lists, and online collaboration platforms, seek peer help, and continuously learn, accelerating their growth.
### Cloud Computing
Cloud computing acts like the conductor of this technological orchestra. It provides on-demand access to a shared pool of computing resources via the Internet, ensuring scalability and accessibility. Companies can dynamically adjust their infrastructure based on needs, eliminating the need for expensive upfront hardware investments.
Cloud services also empower remote work and collaboration by being accessible from anywhere with an internet connection. This democratization of technology through cloud computing fosters innovation and competition in the digital age, allowing businesses of all sizes to leverage powerful computing resources.
<CTA_Middle_Languages />
## Improvisation and Challenges
The world of software development thrives on a constant push-and-pull between creativity, efficiency, and security. This section explores two key challenges that developers face in maintaining this delicate balance:
### Security Scores a discordant Note
It is difficult for various reasons to incorporate security measures into the development process without slowing it down. First, security requirements increase complexity, necessitating more time and work for control implementation and testing. In addition, budgets and schedules may be strained when resources are allocated for security, such as employing people or purchasing equipment.
Furthermore, developers' ignorance or insufficient training may result in missed security holes and delayed compliance. Security evaluations, regulatory compliance, and competing goals between the development and security teams may also hamper development. Ultimately, it might be difficult to integrate security measures into agile operations, which can cause delays and compatibility problems.
### Remote Work
The shift to remote work highlights the need for creative methods and tools for teamwork. When traditional approaches fail to meet real-time needs, workflows become fragmented. Organizations must invest in virtual team-building exercises, project management software, and unified communication platforms to overcome this. It's crucial to get training on remote collaboration tools. Furthermore, developer communities need diversity, equity, and inclusion (DEI) to foster creativity and guarantee equitable opportunities for all.
Underrepresented groups are encouraged to seek jobs in technology by representation and the creative spark provided by diverse perspectives. Encouraging equity guarantees equal chances for everybody, resulting in a more diverse talent pool.
## The Future Crescendo: A Symphony of Innovation
The software development landscape, ever-dynamic and ever-evolving, is poised for a future symphony of innovation. Here are three key areas that will play a major role in how software is developed in the years to come:
### AI as the Maestro
Artificial intelligence (AI) has the potential to act as the maestro, meticulously optimizing development processes and workflows further. Imagine AI-powered tools that can automate the mundane, repetitive tasks that consume developer time. These tools could identify potential bugs early in the development cycle, streamlining the entire process. Even more transformative, AI might generate code based on developer specifications, accelerating development and freeing up valuable human creativity. This newfound creative space will allow developers to focus on the higher-level tasks that truly leverage their unique human capabilities: design, innovation, and strategic problem-solving.
### Ethical Harmonies
As AI assumes the role of a co-pilot within the development workflow, robust methodologies for ethical and responsible AI development become a critical control mechanism. This focus ensures the absence of bias within training datasets and algorithms, promoting fair and accountable AI practices throughout the development lifecycle. We must ensure that these powerful tools are developed and used ethically. Careful consideration must be given to potential biases within AI algorithms and clear guidelines established to ensure AI augments, rather than replaces, human expertise. Open discussions and a collaborative approach to responsible AI development will be crucial for maintaining trust and ethical considerations within the development community.
### Lifelong Learning
The rapid pace of technological change underscores the need for a continuous, never-ending learning process for developers. Embracing a "growth mindset" is key, encouraging developers to actively seek opportunities to learn new technologies, frameworks, and best practices. This "lifelong learning" will be essential for developers to remain relevant and competitive in the ever-evolving landscape. Just like a seasoned musician who refines their skills throughout their career, developers who continuously learn and adapt will be the ones who can contribute the most meaningful compositions to the symphony of technological progress.
## Conclusion
The evolving developer experience incorporates a dynamic interplay of speed, skill, and serendipity, reflecting the multifaceted nature of modern software development. As the developer landscape continues to evolve, embracing agility, continuous learning, and a spirit of exploration is essential to unlocking the full potential of technology and driving meaningful change.

Imagine you're at home, and your house is full of rooms with various doors, some leading to secure areas like your personal office or a safe room. Now, what if someone knew a trick to bypass the usual routes and access these rooms directly, stealing or tampering with your valuables, such as your 419-karat gold chain, expensive perfume, or even your vintage [Kolo box](https://en.wikipedia.org/wiki/Piggy_bank). This is essentially what happens in a path traversal attack.
---
#### What is Path Traversal?
Path traversal, also known as directory traversal, is a type of vulnerability found in web applications. It allows attackers to access files and directories stored outside the web root folder, which they typically shouldn't be able to reach, that's for the chefs, a.k.a Backend Engineers. These files can contain sensitive information like application code, user data, credentials, and even system files, which can be exploited to gain further control over the server.
---
#### How Path Traversal Works
Say there's a web application, a sinister [yahooyahoo](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3999317) online shopping store used to trade illegally, much like [Darkmarket](https://www.europol.europa.eu/media-press/newsroom/news/darkmarket-worlds-largest-illegal-dark-web-marketplace-taken-down), with its name actually being **yahooyahoo**! Dumb I know, had to do with something about hiding in plain _site_ by the admin who's now in jail :). The application loads an image using a URL like this:
```html
<img src="/loadImage?filename=218.png">
```
In the backend, the server processes this request by appending the filename to a base directory:
```
/var/www/images/218.png
```
However, if there are no defenses against path traversal, an attacker; in this case [EFCC](https://www.efcc.gov.ng/efcc/), can manipulate the **filename parameter** to access other files on the server such as account info of the users. For instance, they might try:
```
https://yahooyahoo.com/loadImage?filename=../../../etc/passwd
```
This request instructs the server to load a file by stepping up three directory levels from the base path and then accessing the `/etc/passwd` file, a critical system file on Unix-like systems.
The server constructs the path like this:
```
/var/www/images/../../../etc/passwd
```
The `../` sequence moves up one directory level. So, the path resolves to:
```
/etc/passwd
```
---
#### The Power and Might of `../` Sequence
When you hear of **Sequence** in Web-Sec, just think of **Navigation**.
Think of `../` as a way to go up one level in a directory structure, like climbing a ladder to the floor above:
- A single `../` takes you one level up.
- `../../` takes you two levels up.
- `../../../` takes you three levels up, and so on.
In a computer file system:
- Starting at `/home/user/documents/projects`, `../` takes you to `/home/user/documents`.
- `../../` would take you to `/home/user`.
- `../../../` brings you to `/home`.
---
To better understand this:
Imagine you're in a large hotel, Hotel 3FCC. You start in room 419 (4th floor, 19th room). Using `../`:
- `../` means stepping out into the hallway (up one level in directory terms).
- `../../` means taking the elevator down to the 3rd floor.
- `../../../` means going down to the 2nd floor.
### Hotel Layout:
```
Hotel:
---------------------
(Floors)
|
|
+---------------------------------------------+
| 1st Floor | 2nd Floor | 3rd Floor | 4th Floor |
| | | | |
+-------------+-------------+-------------+-------------+
| | Room 219 | | Room 419 |
| | | | (Your Room)|
| +-------------+ +-------------+
| | Room 220 | | Room 420 |
| | | | |
+-------------+-------------+-------------+-------------+
| | Room 319 | | |
| | | | |
| +-------------+ +-------------+
| | Room 320 | | |
| | | | |
+-------------+-------------+-------------+-------------+
```
### Path Traversal Steps:
1. **Initial Position**: Room 419 on the 4th Floor
- **Current Path**: `/home/user/documents/projects`
- **Hotel Analogy**: You are in Room 419 on the 4th Floor
```
+---------------------------------------------+
| 1st Floor | 2nd Floor | 3rd Floor | 4th Floor |
| | | | |
+-------------+-------------+-------------+-------------+
| | Room 219 | | Room 419 |
| | | | (You) |
| +-------------+ +-------------+
| | Room 220 | | Room 420 |
| | | | |
+-------------+-------------+-------------+-------------+
| | Room 319 | | |
| | | | |
| +-------------+ +-------------+
| | Room 320 | | |
| | | | |
+-------------+-------------+-------------+-------------+
```
2. **Step 1**: Using `../` to move up one level to the hallway of the 4th floor
- **New Path**: `/home/user/documents`
- **Hotel Analogy**: Stepping out into the hallway of the 4th Floor
```
+---------------------------------------------+
| 1st Floor | 2nd Floor | 3rd Floor | 4th Floor |
| | | | |
+-------------+-------------+-------------+-------------+
| | Room 219 | | (Hallway) |
| | | | |
| +-------------+ +-------------+
| | Room 220 | | Room 419 |
| | | | (Empty) |
+-------------+-------------+-------------+-------------+
| | Room 319 | | |
| | | | |
| +-------------+ +-------------+
| | Room 320 | | |
| | | | |
+-------------+-------------+-------------+-------------+
```
3. **Step 2**: Using `../../` to move up two levels to the 3rd Floor
- **New Path**: `/home/user`
- **Hotel Analogy**: Taking the elevator down to the 3rd Floor
```
+---------------------------------------------+
| 1st Floor | 2nd Floor | 3rd Floor | 4th Floor |
| | | | |
+-------------+-------------+-------------+-------------+
| | Room 219 | (You) | (Hallway) |
| | | | |
| +-------------+ +-------------+
| | Room 220 | Room 319 | Room 419 |
| | | (Empty) | (Empty) |
+-------------+-------------+-------------+-------------+
| | Room 320 | | |
| | | | |
| +-------------+ +-------------+
| | | | |
+-------------+-------------+-------------+-------------+
```
4. **Step 3**: Using `../../../` to move up three levels to the 2nd Floor
- **New Path**: `/home`
- **Hotel Analogy**: Taking the elevator down to the 2nd Floor
```
+---------------------------------------------+
| 1st Floor | 2nd Floor | 3rd Floor | 4th Floor |
| | (You) | (Empty) | (Hallway) |
+-------------+-------------+-------------+-------------+
| | Room 219 | Room 319 | Room 419 |
| | | (Empty) | (Empty) |
| +-------------+ +-------------+
| | Room 220 | Room 320 | Room 420 |
| | | | |
+-------------+-------------+-------------+-------------+
```
#### Defenses and Bypasses
To prevent these attacks, many applications strip out directory traversal sequences from user input. But clever attackers often find ways to bypass these defenses. For instance, they might use an absolute path directly from the root:
```
filename=/etc/passwd
```
Or, they might use nested traversal sequences like `....//`, which, after stripping, still leaves a valid traversal sequence:
```
https://yahooyahoo.com/loadImage?filename=....//etc/passwd
```
Here’s how nested sequences work:
- User input: `....//etc/passwd`
- Application strips `../`: The sequence `....//` reverts to `../`
- Resulting path: `/var/www/images/../etc/passwd`
- Final path resolves to: `/etc/passwd`
#### URL Encoding Tricks
Another trick involves URL encoding (I'll be writing an article on URL encoding soon), where characters like `../` are represented in encoded forms (`%2e%2e%2f`). For example:
```
filename=%2e%2e%2f%2e%2e%2fetc/passwd
```
This can trick the application into processing it as valid input.
#### Protecting Against Path Traversal
To defend against path traversal:
1. **Avoid using user input in filesystem APIs** whenever possible.
2. **Validate user inputs rigorously**:
- Use a whitelist of allowed values.
- Allow only specific characters (e.g., alphanumeric).
3. **Canonicalize the path**:
- Ensure the resolved path starts with the expected base directory.
### Real-Life Examples of Path Traversal Attacks
#### 1. **Apache Struts CVE-2017-5638**
In 2017, a critical vulnerability was discovered in Apache Struts, a popular open-source web application framework.

Such vulnerabilities in widely used plugins pose significant risks as they can affect a large number of websites, potentially exposing sensitive data and enabling further attacks.
### Final words
I'm not supposed to be writing an article telling you this (lol), but sometimes the most secure doors have hidden keys – and in the world of web security, path traversal is one key you definitely don't want falling into the wrong hands.
Path traversal vulnerabilities extend beyond what I have shown here but see this as a starting point, a good magician never reveals his secrets :).
Path traversal vulnerabilities are like hidden passages in a fortress, allowing attackers to slip through defenses and wreak havoc. By understanding how these attacks work and implementing defenses, we can better protect our digital fortresses from unauthorized access. Always validate and sanitize user inputs, and regularly, I mean regularly review your code and server configurations to close off any potential exploits.

We all agree that timely project delivery is crucial; collective working can make that happen. Uniform ownership and expertise contributions are necessary, and they are achieved if both developer and designer have effective communication.
No doubt the actual tasks of [designers and developers are different](https://blog.hubspot.com/website/web-designer-vs-web-developer), but the end goal of both teams should be to develop a successful product. So, collaboration is necessary to bridge the gap between a designer and a developer in a professional relationship.
In this article, we will see tips for improving collaboration between designers and developers. Let’s explore how!
## Why is the Designer and Developer Collaboration important?
To create an outstanding product, developers and designers must work in sync, with clear and close communication maintained throughout the project.
They should cultivate the habit of working together, solving errors, and implementing new features and technologies. While sharing their ideas, experts might encounter friction, but it shouldn’t affect the overall project development.
The selected idea may fail. However, blaming the idea giver isn’t appreciated in a professional setting. Whether things go right or fail, communication and collaboration shouldn’t be stopped.
## Tips for Effective Designer and Developer Collaboration
Healthy communication between developers and designers hinges on effective collaboration. Having a collaborative mindset is necessary to make the development process manageable.
Building regular check-ins and using open dialogue and design systems ensures efficiency and alignment. Here are some tips that can help improve effective communication between developers and designers.
### Set Goals First
Conducting a meeting to set [primary goals will improve the collaboration](https://fireflies.ai/blog/meeting-goals-for-productive-collaboration) between the team.
It is crucial to set clear goals on which the whole team will work. It matters a lot to discuss the goals and potential solutions to achieve them in both virtual and in-office environments.
Discussing what your business is expecting and making some ground rules can prevent expensive mishappenings and bring some good ideas.
It’s a perfect alternative for the team to discuss the what, who, where, why, when, how, and more about the members and the project. Once the primary communication about the project is done, developers and designers have a clear idea of their tasks.
### Clear Understanding of Roles and Responsibilities
Designers & Developers should mutually appreciate each other’s expertise. UX designers' tasks might involve grasping the [fundamentals of the developer’s tasks](https://www.coursera.org/articles/software-developer). Such understanding enables an insight into the developer's view and the intricate procedure of bringing functionality and [UX design specifications](https://blog.openreplay.com/ux-best-practices-for-developers/) to fulfillment.
However, the question is- whether UX designers possess coding skills. Normally, it depends on different team standards. Designers can directly communicate with developers to know their expectations. Regular regular communications like weekly or monthly meetings, where designers and developers can exchange insights into their respective roles, can generate understanding between them and their tasks.
### Communication is the Key
Recurrent communication between your team is necessary to make your project successful. Frequent communication doesn’t mean sending numerous emails in a day.
Emails should be used to summarize some discussion, but they can sometimes be problematic. Sometimes, communicating through emails can lead to unintentionally ignored information; sometimes, your writing tone might be different from that of another person, creating a wrong impression of you.
This is especially necessary for developers and designers. They often face situations from multiple expectations, conflicts in ideas, and speaking in different language.
All team [members should communicate often](https://semaphoreci.com/blog/dev-team-communication), either via phone, video conferencing, or in person. It ensures the whole team is at one pace and isn’t lost in performing non-relevant tasks. Ultimately, it builds trust and communication between the team.
### Promote constructive feedback
Feedback, whether suggested or received, is an integral part of the design process. Designers should gather suggestions from different sources, such as developers, users, stakeholders, and marketing specialists. However, it is necessary to ensure that [feedback is constructive](https://www.invisionapp.com/inside-design/give-designers-feedback/) unbiased and not based on personal preferences.
Feedback should always be made by keeping business goals in mind. For instance, if the button is placed on the bottom, and you think that it should be on the top, here’s how you can give your feedback:
“*I like this template design, but I think the call to action should be located in the middle. Our A/B tests show that this location for a CTA will help us increase sales by 20%.*” This is considered as constructive feedback.
<CTA_Middle_Basics />
### Work with Design Systems
A Design system is a style guide and a pattern library. It consists of different reusable components like CTA buttons, drop-down menus, lead forms, etc., along with constructive instructions on [how to use these components](https://help.figma.com/hc/en-us/articles/360038663154-Create-components-to-reuse-in-designs).
Working with a defined system of components, businesses can reduce optional technical features. Such extra features might have been created by building the same UI elements more than once. Reusable components help with faster delivery and maintain consistency throughout the app.
The [style guide in the design system](https://www.invisionapp.com/inside-design/guide-to-design-systems/) is a set of rules for identifying a brand. A particular brand follows a decided color scheme, typeface and font, and a personalized template design. As the company expands its website, the style guide also expands. Hence, it becomes a pattern library.
A pattern library has all interactable functions present in your design, such as navigation bars, buttons, and carousels. It contains descriptions of these elements, instructions about their uses, and associated code.
The style guide and pattern library together form a design system. The design system provides complete data on all the designs used in the project.
### Using Different Collaborative Tools
The traditional designer-developer collaboration process involves designers creating screens and sharing them with developers. Then, developers provide feedback on what can and cannot be done from that screen.
The designers then remake the screens and share them again with the developers, and the process continues until everything from the screen is possible. Thus, it becomes time-consuming and tiresome and might also create conflicts.
Designer-developer collaboration aims to avoid this lethargic process. Instead, get the same screen and environment where real-time editing is possible.
There are certain tools available for easy collaboration [such as Adobe XD](https://helpx.adobe.com/in/xd/help/collaborate-coedit-designs.html) that are inclined more toward the designer’s requirements and support the process from beginning to complete designs.
[Tools like Figma](https://blog.openreplay.com/plan-your-ui-with-figma/) help with the real-time collaboration of developers and designers. These tools are easy to integrate with project management [tools like JIRA](https://www.atlassian.com/software/jira).
### Design and Development Process Integration
A strong hindrance for both developers and designers is moving from designing the system to its development. But there are a lot of tools that can help you with this process.
Apps that make development and designing easier will be helpful for you. It’s the best way to keep everything organized in one place, keep simpler track of them, and later manage them seamlessly. Using such useful tools leads to better and quicker outcomes. Moreover, if each team member is working on the same platform, it can create wonders by making communication channels between them easy!
Sometimes, you have to dig around in the help section of your app to find it, but design and development process integration can save resources. It’s also useful while using multiple apps for working and helps in linking them to make things easier to handle for you.
The fewer the app interfaces, the greater the convenience of work, and ultimately, designer-developer communication is increased. So the end product can be successfully built and deployed on time.
## Conclusion
Ultimately, we hope you have explored all the primary tips for effective collaboration between designers and developers. You can build a collaborative environment to get creative ideas from all your team members, whether a fresher or an expert. After all, each team member has their importance and skillset to make the project successful. So, cultivate a collaborative space for the team and let them put their ideas on the table!

1,889,598 | Best PostgreSQL GUI Tools | Let's take a look at the list of the four best PostgreSQL GUI applications for dealing with data visually. | 0 | 2024-06-15T14:26:11 | https://writech.run/blog/best-postgresql-gui-tools/ | postgres, programming, sql | **TL;DR:** There are many database GUI tools available, but only a few of them have been designed specifically for PostgreSQL. If you want to manage your PostgreSQL databases effortlessly, you must adopt an advanced PostgreSQL GUI tool. Here, you can find a list of the four best PostgreSQL applications for you.
When the first version of PostgreSQL was released, the only way to access data was to run queries from the command line. As you can imagine, interacting with a database via the command line is something that only skilled users can do. This is because you need to know the PostgreSQL language in depth.
Over time, the needs of end users have evolved for developers, data scientists, and data analysts alike. As a result, several PostgreSQL GUI tools have entered the market, and you can now choose between many PostgreSQL clients.
If you've ever felt limited by your PostgreSQL GUI tool or never used one, this article might shed some light on which one to choose. This article will dig into the four best PostgreSQL GUI tools for developers. But first, let's take a look at why you should be using one and which criteria were considered while making the list.
## Why You Need a PostgreSQL GUI Tool
Adopting a PostgreSQL GUI tool can bring many advantages to your data management process:
- **Visual feedback:** Managing data visually in the tool makes everything easier and opens the databases to non-technical members of your team.
- **Better data management:** A GUI tool specifically designed to handle PostgreSQL databases makes data management easier.
- **Scalability:** You can use the same tools to connect to several PostgreSQL databases and manage them all.
## Elements of a Good PostgreSQL GUI Tool
There are several aspects to consider when selecting and evaluating PostgreSQL GUI tools:
- **Most commonly used:** The more people who adopt the tool, the more documentation there will be online. After all, it's easier to get support if a tool is backed by a large community. This is more likely to happen if the tool is available on all major operating systems.
- **Easy to use and learn:** PostgreSQL is a complex technology, and this is why a GUI tool should make everything easier. A good PostgreSQL GUI tool should be easy to learn and should not require several hours of training.
- **Plugin support:** The ability to extend the PostgreSQL GUI tool with plugins developed by the community makes it future-ready, as new features can be introduced into the tool at any time.
- **Customizable user interface:** You should be able to customize the tool to fit your particular needs. The more customizable the user interface of a PostgreSQL GUI tool is, the better the resulting user experience will be.
- **Fast and reliable:** The tool should be free of major bugs and ensure good performance without using too many resources. Non-technical team members may not be able to run a PostgreSQL GUI tool that requires several GB of RAM because they typically don't have hardware as powerful as technical team members.
## Top Four PostgreSQL GUI Tools
Here is a list of four PostgreSQL GUI tools that meet the criteria presented earlier, in alphabetical order:
- DbVisualizer
- OmniDB
- pgAdmin
- TablePlus
### DbVisualizer
[DbVisualizer](https://www.dbvis.com/) is one of the most reliable database GUI tools on the market. The first version was released in 1999, and it now supports all major databases, including PostgreSQL. DbVisualizer is the database GUI tool with the [highest user satisfaction on G2](https://www.g2.com/categories/database-management-systems-dbms?tab=highest_rated) and has even been adopted by NASA.
DbVisualizer can be installed on Windows, macOS, and Linux; all it needs to run is Java. Its Java nature makes it a bit slower than other tools, but performance is not the main goal of DbVisualizer.
Instead, DbVisualizer aims for completeness and reliability. It therefore provides a wide range of features for writing SQL queries, visualizing data, and designing and developing databases, tables, relations, indexes, and triggers. DbVisualizer also offers in-depth help when it comes to PostgreSQL and supports all its unique features.
Even though the DbVisualizer UI may appear a bit outdated compared to the other tools, you can [configure it in several ways](https://confluence.dbvis.com/display/UG120/Changing+the+GUI+Appearance), like using a dark theme.
As opposed to OmniDB and TablePlus, DbVisualizer is a proprietary tool that does not support plugins. On the other hand, it offers several advanced features. One of the most important ones is the ability to visually build queries, which allows even non-technical people to perform SQL queries. DbVisualizer also comes with a query optimization feature that explains to you how and why you can improve your SQL query. It shows you how your query will be processed by the database, telling you whether or not an index will be used.
### OmniDB
[OmniDB](https://github.com/OmniDB/OmniDB) is a GUI tool that supports several databases, such as MySQL, PostgreSQL, Oracle, and MariaDB. However, its main focus is PostgreSQL. OmniDB is an open source project developed mainly by [2ndQuadrant](https://github.com/2ndQuadrant), one of the leading companies in the world when it comes to PostgreSQL.
With OmniDB, you can add, edit, manage, and monitor data in a PostgreSQL database through a simple GUI interface. Even though its UI isn't fully customizable, OmniDB supports both a light and dark theme. You can also [configure several shortcuts](https://omnidb.readthedocs.io/en/2.17.0/en/11_additional_features.html#user-settings) for accessing OmniDB features more easily, such as running a query.
OmniDB supports Windows, Linux, and macOS and allows developers to add and share new features via plugins, so it can be extended by the community. On the other hand, the OmniDB community is still small compared to those of the other tools, which means there may be limited support for issues.
Its main strength is the ability to visualize queries to help you find bottlenecks. It also comes with a smart and advanced SQL editor with autocomplete and syntax highlighting features that help you write SQL queries.
At the time of writing, the latest version of OmniDB is still in beta. This means that it may have some bugs and performance issues. In other words, OmniDB may look incomplete or unreliable compared to more mature tools such as DbVisualizer.
### pgAdmin
[pgAdmin](https://www.pgadmin.org/) is one of the most popular, most used, and most reliable PostgreSQL GUI tools available. This is because pgAdmin was developed by part of the PostgreSQL team and directly comes in the PostgreSQL installation pack. However, compared to the other tools, it is the sole GUI application that supports only PostgreSQL.
pgAdmin is an open source project that supports all PostgreSQL features, from performing simple SQL queries to building complex databases. As with DbVisualizer, though, pgAdmin does not support plugins and cannot be extended by the community. At the same time, it's open source, so community extensions and plugins are not impossible.
You can install pgAdmin on Windows, Linux, and macOS, and it runs as a web application that can be deployed to any server. This makes it also available from the cloud, so pgAdmin is a tool you can use anywhere.
The pgAdmin user interface is simple for beginners, but it also offers several shortcuts for experienced users. This makes it an easy-to-learn yet advanced tool that can be used by any member of the team. However, the UI isn't highly customizable and might look a bit outdated when compared to TablePlus, for example.
### TablePlus
[TablePlus](https://tableplus.com/) is a database GUI app for relational databases. In detail, it supports MySQL, PostgreSQL, SQLite, and more. So, just like OmniDB and DbVisualizer, you can also use it for non-PostgreSQL scenarios. TablePlus has been adopted by companies such as Spotify and Intel, making it one of the more interesting PostgreSQL GUI tools on the market. This makes it a reliable tool that's directly comparable with DbVisualizer.
TablePlus is a fast and native GUI tool that comes with a simple-to-use UI. You can run TablePlus almost everywhere, considering it supports iOS, macOS, and Windows. Plus, there is also an [alpha version for Linux](https://tableplus.com/blog/2019/10/tableplus-linux-installation.html).
The TablePlus user interface is nice and simple but also highly configurable. This makes it a versatile tool that can be easily adapted to the needs of several users. On the other hand, finding the right UI configuration for you may take a lot of time.
TablePlus also supports several shortcuts for more skilled users. The tool has been developed with performance and security in mind. TablePlus is very lightweight, supports built-in SSH connections, and ensures that your credentials are stored securely. This makes it the best-performing tool of the four. Moreover, just like OmniDB, TablePlus can be easily extended by plugins developed by the community.
## Conclusion
A PostgreSQL client is an essential tool when it comes to data management. PostgreSQL clients are particularly important because they make databases simpler for non-engineer members of your team. Data is easier to use and understand, allowing your engineers to save time while supporting the team.
This article explained why you need a PostgreSQL GUI tool and how to identify a good one. You learned about four of the best PostgreSQL GUI tools on the market. TablePlus, OmniDB, and DbVisualizer support other database technologies and have excellent features to support PostgreSQL-based data management processes, while pgAdmin is the only tool officially supported by PostgreSQL developers. Keep in mind that the tool that suits you the best depends on your use cases. So, there is no real winner.

As part of my coding journey, I’ve been diving into the key concept of loops in JavaScript. Recently, I had the opportunity to build a small web app that reminds me of a digital encyclopedia or Pokédex, but instead of featuring fictional creatures, it showcases real animals from around the world. It’s been an great experience learning how to manipulate data and create interactive user interfaces.
At the heart of this project is an array of objects called `animalsArr`, which contains information about various animals, including their names, classes (mammal, bird, reptile), diet (herbivore or not), continent of origin, YouTube video embed codes, and descriptions. It’s like having a mini-encyclopedia right at your fingertips!
To bring this data to life, I used JavaScript to dynamically generate a grid of clickable animal images. Here’s a snippet of the code that makes it happen:
```
for (let i = 0; i < animalsArr.length; i++) {
const animal = animalsArr[i];
const filename = animal.name.toLowerCase().replace(' ', '-');
const img = `<img onclick="swapImage(${i})" src="images/${filename}.jpg" />`;
animalPicDiv.innerHTML += img;
}
```
In this loop, we iterate through each object in the `animalsArr` array. For each animal, we create an `<img>` tag with the appropriate file name (derived from the animal’s name) and add an `onclick` event that calls the `swapImage` function with the current index `i`. This allows us to keep track of which animal was clicked.
The real magic happens in the `swapImage` function:
```
function swapImage(i) {
const animal = animalsArr[i];
animalNameHeading.textContent = animal.name;
animalDescriptionParagraph.textContent = animal.desc;
videoPlayerDiv.innerHTML = `<iframe width="560" height="315" src="https://www.youtube.com/embed/${animal.youTube}" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>`;
}
```
When an animal image is clicked, this function is called with the corresponding index `i`. It retrieves the animal object from the `animalsArr` array and updates the heading and description elements with the animal’s name and description. Additionally, it dynamically generates an `<iframe>` tag to embed the animal’s YouTube video, using the `youTube` property from the object.
It’s cool to see how a simple array of objects can be transformed into an engaging and informative web app. The power of loops and JavaScript’s ability to manipulate the DOM make it possible to create interactive experiences like this.
Building this animal encyclopedia has been a great exercise, and it’s just the beginning. The possibilities are endless when it comes to creating dynamic web applications using JavaScript. I’m stoked to explore more advanced concepts and build even more exciting projects in the future.
If you’re curious about the code behind this project or want to learn more about loops and working with arrays of objects in JavaScript, feel free to check out the complete source code on the repo! Happy coding, and keep let’s keep exploring the wonders of the animal kingdom! | rkrevolution | |

# Using CSS when/else rules
If you have wondered why [CSS](https://en.wikipedia.org/wiki/CSS) holds such importance in web development, the answer becomes clear once you understand its role in shaping the visual aspects of websites. As we all know, [CSS (Cascading Style Sheets)](https://en.wikipedia.org/wiki/CSS) plays a significant role in developing good-looking web pages as they control the layout, colors, fonts, and various design elements. However, what if there was a way to go beyond the traditional approach and apply styles conditionally based on specific criteria? In this article, we will explore the proposed CSS [`@when/@else`](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Conditional_Rules) rules, which can enable developers to achieve precisely that.
It’s important to note that these rules are still in the proposal stage and are not part of the standard CSS implemented in browsers yet. Therefore, they cannot be used in production environments at this time. Developers can look forward to these features being adopted in the future, which will enhance the power and flexibility of CSS for conditional styling. Please see this [W3C module](https://www.w3.org/TR/css-conditional-5/#when-rule) for more information.
That being said, let's dive in to understand what the `@when/@else` rules are.
## Understanding CSS `@when/@else` rules
With CSS, `@when/@else` rules provide a mechanism for applying styles selectively based on specific conditions. In simpler terms, they allow developers to define a set of styles to be applied when a condition is met and an alternative set of styles when it is not. This approach differs from [traditional CSS](https://developer.mozilla.org/en-US/docs/Learn/CSS/First_steps/How_CSS_is_structured), where styles are applied universally.
Below is a table that distinguishes the `@when/@else` rules from the traditional CSS.
| Aspect | CSS `@when/@else` Rules | Traditional CSS Approaches |
|-------------------------|-------------------------------------|-----------------------------------|
| Selective Styling | Styles can be applied conditionally | Styles are applied universally |
| Dynamic Adaptability | Allows for responsive design | Limited flexibility in styling |
| Specific Conditions | Styles can be based on criteria | Styles applied without conditions |
| User Interaction | Enables interactive styling | Limited interactivity |
| State and Event Styling | Different styles for various states | Limited state-based styling |
| Customization | Highly customizable | Less customization options |
| Usability and Aesthetics| Enhances user experience | Standard styling practices |
In traditional CSS, styles are universally applied to elements that match a selector.
For example:
```css
.nav {
display: flex;
justify-content: space-between;
background-color: #333;
color: #fff;
padding: 1rem;
}
.nav-item {
margin-right: 1rem;
}
/* Responsive styles */
@media (max-width: 768px) {
.nav {
flex-direction: column;
}
.nav-item {
margin-right: 0;
margin-bottom: 0.5rem;
}
}
```
This traditional CSS approach applies the main styles for the `.nav` and `.nav-item` universally, while the responsive styles inside the `@media` target specific screen widths to modify the layout and spacing for smaller screens.
Here's an example using the `@when/@else` rule syntax:
```css
/* Using @when and @else */
@when media(max-width: 768px) and supports(display: flex) {
.nav {
flex-direction: column;
}
.nav-item {
margin-right: 0;
margin-bottom: 0.5rem;
}
}
@else {
.nav {
display: flex;
justify-content: space-between;
background-color: #333;
color: #fff;
padding: 1rem;
}
.nav-item {
margin-right: 1rem;
}
}
```
As you can see, with the `@when` rule, we check if the screen width is less than or equal to `768px` and if the browser supports Flexbox. If both conditions are true, the first block of styles is applied (vertical layout). Otherwise, the `@else` block provides the traditional horizontal layout.
NOTE: The `@when` and `@else` rules simplify conditional styling, making your CSS more concise and easier to manage.
## Benefits of using the `@when/@else` rules
Now that we have a glimpse of CSS's `@when/@else` rules let's explore some of its benefits.
### Generalization with `@when`
The `@when` rule generalizes conditionals, allowing you to combine different queries (such as `@media` and `@support`) into a single statement. You can wrap multiple conditions into one block instead of writing separate conditional rules for specific tasks.
For example, suppose you want to test whether a media screen is below `769px` and whether the browser supports both grid and flex display features. With `@when`, you can create a generalized rule like this:
```css
@when media(max-width: 769px) and supports(display: grid) and supports(display: flex) {
.grid {
grid-template-columns: 1fr;
}
.flex {
flex-direction: row;
}
}
```
In the above code, the `@when` rule is followed by the [media query](https://www.w3schools.com/css/css3_mediaqueries.asp) condition `(max-width: 769px)` and the `supports` conditions for `display: grid` and `display: flex`. Inside the rule, the styles for the `.grid` and `.flex` classes are specified accordingly.
### Mutually exclusive rules with `@else`
The `@else` statement allows you to write [mutually exclusive](https://medium.com/@hayavuk/mutually-exclusive-selectors-9e8bd29baafb) rules. If the conditions in the `@when` block are evaluated as false, the CSS engine ignores that style block and falls back to default styles. For instance, you can create styles that apply only when certain conditions are met; if not, the fallback styles take effect.
### Improved readability
Using [comparison operators](https://www.codecademy.com/article/fwd-js-comparison-logical) in `@when` and `@else` makes media queries easier to read and understand. It simplifies complex logic by combining multiple conditions into concise statements.
### Support extensions
The [Level 4 CSS update](https://css-tricks.com/css4/) includes extensions to support rules, allowing testing for supported font technologies and other features.

## Implementing `@when/@else` rules in CSS
To implement the `@when/@else` rules, we can use a combination of CSS selectors and properties.
Here’s a step-by-step guide on how to implement the `@when/@else` rules in CSS:
- Check browser support: Before you start, verify if your target browser supports the `@when/@else` rules. You can check resources like “[Can I use](https://caniuse.com/css-when-else)” for the most current information.
- Write the base CSS: Define the base CSS styles that will apply regardless of conditions.
- Define your conditions: Determine the conditions under which you want to apply different styles. These can be based on media queries, feature support, or other environmental conditions.
- Use `@when` to apply conditional styles: Start with the `@when` rule followed by your condition in parentheses. Inside the curly braces `{}`, write the CSS rules that should apply when the condition is true.
- Use `@else` for alternative styles: Follow the `@when` block with an `@else` block. Inside the `@else` curly braces, write the CSS rules that should apply when the `@when` condition is not met.
- Test your styles: After implementing your conditional rules, test them across browsers and devices to ensure they work as expected.
Here’s an example to illustrate the process:
```css
/* Base CSS */
.container {
padding: 20px;
}
/* Conditional CSS */
@when media(max-width: 600px) {
.container {
padding: 10px; /* Smaller padding for narrow screens */
}
}
@else {
.container {
padding: 20px; /* Default padding */
}
}
```
In this example, the `.container` will have a padding of `10px` if the viewport width is less than `600px`. Otherwise, it will default to a padding of `20px`.
Now, let's take a look at common use cases.👇
- Responsive design: Adjusting layout and font sizes based on viewport dimensions. For example, switching from a multi-column layout to a single-column layout on mobile devices.
- Feature detection: Applying styles only if certain CSS features are supported by the browser. For example, using grid layout styles only if the browser supports CSS Grid.
- Environment adaptation: Changing styles based on user preferences or environmental conditions like dark mode. For example, a dark color scheme can be applied if the user has set their system to dark mode.
- State-based styling: Modifying styles based on the state of an element, such as hover or focus. For example, changing the background color of a button when it is hovered over.
- Fallbacks for older browsers: Providing alternative styles for browsers that do not support modern CSS properties. For example, using flexbox as a fallback for browsers that do not support grid layout.
Here’s an example that combines responsive design and feature detection:
```css
/* Base styles */
.container {
display: flex;
flex-wrap: wrap;
}
/* Conditional styles */
@when media(max-width: 600px) and supports(display: grid) {
.container {
display: grid;
grid-template-columns: repeat(auto-fill, minmax(150px, 1fr));
}
}
@else {
.container {
display: flex;
flex-direction: column;
}
}
```
In this example, if the viewport is less than `600px` wide and the browser supports CSS Grid, the `.container` will use a grid layout with flexible columns. If not, it will default to a flex column layout.
## Advanced techniques for CSS `@when/@else` rules
Advanced Techniques for CSS `@when/@else` rules offer more control over styles based on different conditions like complex media queries, feature detection, or custom environmental factors. This section talks about advanced approaches and tips that help optimize the usage of `@when/@else` rules.
Let's go!
### Combining with CSS preprocessors
[CSS preprocessors](https://developer.mozilla.org/en-US/docs/Glossary/CSS_preprocessor) like [Sass](https://sass-lang.com/) or [LESS](https://lesscss.org/) can enhance the `@when/@else` rules by allowing you to use [variables](https://www.w3schools.com/css/css3_variables.asp), [functions](https://www.w3schools.com/cssref/css_functions.php), and other programming concepts within your CSS.
Here’s an example using Sass:
```css
$breakpoint: 600px;
@mixin responsive($property, $value) {
@when media(max-width: $breakpoint) {
#{$property}: $value;
}
@else {
#{$property}: adjust-value($value);
}
}
.container {
@include responsive(padding, 20px);
}
```
In the code above, the responsive [mixin](https://www.w3schools.com/sass/sass_mixin_include.php) applies different padding values based on the viewport width, using a variable for the breakpoint.
To learn more about Sass, read [this](https://www.creativebloq.com/how-to/get-started-with-sass).
### Dynamic styling based on conditions
[Dynamic styling](https://developer.mozilla.org/en-US/docs/Web/API/CSS_Object_Model/Using_dynamic_styling_information) can be achieved by setting [CSS variables](https://www.w3schools.com/css/css3_variables.asp) or classes that change styles based on certain conditions. For instance, JavaScript can be used to toggle a class based on user interaction or environmental changes.
Here's an example(JavaScript code):
```javascript
window.addEventListener('resize', () => {
if (window.innerWidth < 600) {
document.body.classList.add('mobile');
} else {
document.body.classList.remove('mobile');
}
});
```
CSS code:
```css
body.mobile .container {
/* Styles for mobile */
}
@else {
.container {
/* Default styles */
}
}
```
The JavaScript listens for window resize events and adds or removes a ‘`mobile`’ class to the body, which could trigger different styles based on the `@when/@else` rules.
### Responsive design using `@when/@else` rules
[Responsive design](https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Responsive_Design) aims to make web applications look good on all devices. With the `@when/@else` rules, you could write more readable media queries.
For example:
```css
@when media(max-width: 768px) {
.column {
width: 100%;
}
}
@else {
.column {
width: 50%;
}
}
```
This example changes the column width based on the viewport size, making it responsive to different device screens.
## Best practices for `@when/@else` rules
When working with CSS, especially with the proposed `@when/@else` rules, it’s important to follow best practices to write efficient and maintainable code. Here are some tips and debugging strategies:
- Plan your CSS: Before writing your CSS, plan the styles that will be needed, the different layouts, and specific overrides. Avoid too much overriding.
- Use flexible units: For maximum flexibility, use relative units like ems, rems, percentages, or viewport units.
- Keep it consistent: Whether you’re working alone or with a team, consistency in naming conventions, color descriptions, and formatting is key.
- Comment your CSS: Comments can help you and others understand the structure and purpose of your CSS. Use them to separate logical sections.
## Debugging `@when/@else` rules
When you come across issues with the functionality or appearance of the `@when/@else` rules, it's important to use debugging techniques to identify and fix the underlying problems.
Here are some debugging techniques:
- Browser [DevTools](https://developer.chrome.com/docs/devtools/overview): Modern browsers come with DevTools that allow you to inspect elements and see which CSS rules are being applied. Use this to troubleshoot unexpected behaviors.
- Isolation: If a particular set of rules isn’t working as expected, try isolating them in a separate stylesheet or HTML document to see if other styles are interfering.
- Process of elimination: Temporarily comment out other CSS rules to see if they are causing the issue.
## Conclusion
In our discussion, we explored the concept of `@when/@else` rules in CSS, which are part of a proposed extension to CSS conditionals. We covered their syntax and potential use cases and provided a step-by-step guide on how they might be implemented. We also discussed advanced techniques, such as combining these rules with CSS preprocessors and using them for responsive design. Although these rules offer promising benefits for readability, maintainability, and flexibility in styling, it’s important to note that they are not yet part of the standard CSS implementation and thus are not supported in current browsers.
For further reading and learning, you can check the following resources:

These tools help manage and automate tasks within your Kubernetes cluster, ensuring things get done when they should. Let's break it down in simple terms.
## Jobs: The Task Managers of Kubernetes
Imagine you have a list of tasks to complete, like cleaning your room or finishing a report. In Kubernetes, a Job is like a task manager that ensures these chores get done. When you create a Job, you’re telling Kubernetes, “Hey, please run this task for me, and make sure it’s completed successfully.”
## How it works:
- Create the Job: You define what needs to be done in a Job manifest. Think of it as a to-do list.
- Run the Job: Kubernetes takes this manifest and runs the task.
Check Completion: It makes sure the task finishes. If it fails, Kubernetes will try again until it succeeds (or hits a limit you set).
- This is perfect for tasks that need to be run once or just a few times, like processing a batch of data or sending a notification email.
## Diving Deeper into Job Configurations
- Parallelism: Controls how many pods can run concurrently. If the parallelism field is not specified, the default value is 1. This means only one pod will be created at a time.
- Completions: Specifies the number of successful completions needed. If the completions field is not specified, the default value is 1. This means the job is considered complete when one pod successfully completes.
- BackoffLimit: Sets the number of retries before the Job is considered failed. If the backoffLimit field is not specified, the default value is 6. This means the job will retry up to 6 times before it is marked as failed.
## Example Manifest file:
```
# job-definition.yaml
apiVersion: batch/v1
kind: Job
metadata:
name: advanced-job
spec:
parallelism: 3
completions: 5
backoffLimit: 4
template:
spec:
containers:
- name: example
image: busybox
command: ["sh", "-c", "echo Job running... && sleep 30"]
restartPolicy: OnFailure
```
This Kubernetes Job will create a pod using the busybox image, run a command that prints a message, and sleep for 30 seconds. It will run up to 3 pods in parallel until 5 successful completions are achieved. If a pod fails, it will be retried up to 4 times before marking the Job as failed. The pod will be restarted only if it fails.
## CronJobs: Your Scheduled Assistants
CronJobs extends Jobs by allowing you to schedule tasks at specific times or intervals. If Jobs are your reliable friends, CronJobs are those friends who show up at the same time every week to help with recurring tasks.
## How it works:
- Define the Schedule: You set up a CronJob with a schedule, using the Cron format (a standard way to specify time intervals).
- Automate the Task: At the specified times, Kubernetes will automatically create Jobs to perform the task.
- Repeat: It keeps running these tasks on the schedule you set, whether that’s every hour, day, week, or month.
CronJobs are ideal for repetitive tasks, such as backing up databases, cleaning up logs, or generating reports.
Note: Cron Syntax: Cron format consists of five fields (minute, hour, day of month, month, day of week) and a command.
```
* * * * * - every minute
0 * * * * - every hour
0 0 * * * - every day at midnight
```
## Example Manifest file:
```
# cronjob-definition.yaml
apiVersion: batch/v1
kind: CronJob
metadata:
name: example-cronjob
spec:
schedule: "0 0 * * *"
jobTemplate:
spec:
template:
spec:
containers:
- name: example
image: busybox
command: ["sh", "-c", "echo CronJob running... && sleep 30"]
restartPolicy: OnFailure
```
This CronJob is configured to run a container named "example" using the "busybox" image every day at midnight. The container executes a shell command that prints a message and sleeps for 30 seconds. If the job fails, it will be restarted.
## Real-World Scenarios
- Data Processing:
Job: Run a data processing script to analyze yesterday’s sales figures.
CronJob: Automatically run this script every night at midnight.
- System Maintenance:
Job: Clean up old, temporary files to free up space.
CronJob: Schedule this cleanup to happen every Sunday at 3 AM.
- Notifications:
Job: Send a welcome email to a new user.
CronJob: Send a daily summary email to all users at 8 AM.
## Conclusion
Jobs and CronJobs in Kubernetes are your reliable helpers, taking care of tasks efficiently and on time. Jobs ensures one-time tasks get done, while CronJobs handles recurring tasks effortlessly. By leveraging these tools, you can automate and manage your workloads effectively, freeing up time to focus on more critical aspects of your projects. | piyushbagani15 |

Animation brings life to a digital application. Modern web applications leverage animations and transitions to create an engaging user experience. Proper application of animations can build a strong connection between the users and the content of a web application. In the past, developers relied on [`setTimeout`](https://developer.mozilla.org/en-US/docs/Web/API/setTimeout) and [`setInterval`](https://developer.mozilla.org/en-US/docs/Web/API/setInterval) to perform JavaScript animations. These traditional methods invoke a function 60 times per second to imitate a smooth animation. Their inconsistencies and unnecessary repaint prompted a more performant and reliable method. [Paul Irish](https://www.paulirish.com/2011/requestanimationframe-for-smart-animating/) introduced the [`requestAnimationFrame`](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) (rAF) in 2011 as a better approach for web animation. This method allows the browser to decide the repaint rate, optimizing web animations.
## What is `requestAnimationFrame`?
The `requestAnimationFrame` is a method provided by browsers for animations in JavaScript. It requests the browser to invoke a specified function and update an animation. The `requestAnimationFrame` receives a single argument, a `callback` function, called at intervals. The frequency of `callback` function calls matches a display refresh rate of 60Hz. This frequency is equal to 60 cycles/frames per second. Its syntax is as follows:
```javascript
requestAnimationFrame(callback)
```
Invoking the `requestAnimationFrame` schedules a single call to the `callback` function. Animating another frame involves repeatedly calling the `requestAnimationFrame` method. Nevertheless, understanding its role in efficient animation is essential.
### What is the Role of `requestAnimationFrame` in Efficient Animation?
The `requestAnimationFrame` method plays a vital role in efficient animation. It synchronizes animations with the browser's rendering cycle. The higher the frame rate, the smoother the animation. But, a higher frame rate requires more resources, impacting performance.
Unlike the conventional approach, the `requestAnimationFrame` can achieve optimal frame rate by:
* Enabling the browser to decide the next repaint cycle and optimize it.
* Limiting animations to a 60Hz display refresh rate, ensuring smooth and efficient animations.
* Reducing unnecessary central processing unit (CPU) usage and conserves resources.
The following section will discuss stopping an animation request.
### Canceling the `requestionAnimationFrame`
JavaScript animation with `requestAnimationFrame` involves recursively calling a function to execute a particular code block. Allowing further calls to the `callback `by `requestAnimationFrame` after completing an animation can lead to memory leaks and affect performance. Fortunately, JavaScript provides the `cancelAnimationFrame` method to stop further requests to the browser to refresh the `callback` function after a completed animation. Consider the syntax below:
```javascript
function callback() {
// animation code block
}
const requestId = requestAnimationFrame(callback);
cancelAnimationFrame(requestId);
```
When invoked, `requestAnimationFrame` returns a long integer value uniquely identifying the entry in the `callback` list. This value gets assigned to the `requestId` variable. Passing the `requestId` to the `cancelAnimationFrame` method cancels the refresh `callback` request.
## Why `requestAnimationFrame`?
The `requestAnimationFrame` provides an efficient way to schedule animation in web browsers. The `requestAnimationFrame` offers several benefits, including:
* It allows the browser to update animation states precisely between frames. This consistency results in smooth, higher-fidelity animations.
* It repaints less often in hidden or inactive tabs and during CPU overload. This phenomenon helps conserve system resources, leading to much longer battery life.
* It leverages hardware acceleration in modern browsers to optimize animations. This approach enhances performance and reduces CPU load in devices with limited resources.
## Utilizing `requestAnimationFrame` in `React`
Performing animations with `requestAnimationFrame` in `React` introduces intricacies distinct from Vanilla JavaScript. It involves a good understanding of `state`, `props`, and [`React's` life-cycle methods](https://react.dev/learn/lifecycle-of-reactive-effects). Efficient side effects management is essential for consistent performance and behavior. Let's see how to achieve these in the later sub-sections.
### Managing Side-effects with Hooks
`React` provides several hooks to manage side effects within a `React` component. For this implementation, we will use the essential hooks. Consider the following approach to create a progress counter that stops at 100:
```jsx
import { useEffect, useRef, useState } from "react";
export default function App() {
const [value, setValue] = useState(0);
const runAgain = useRef(performance.now() + 100);
const progressTimer = useRef(performance.now() + 100);
const requestIdRef = useRef(0);
function nextFrame(timestamp) {
if (runAgain.current <= timestamp) {
// Run the animation
if (progressTimer.current <= timestamp) {
// When the native timestamp catches up to the set interval
//animate the element with the current value
const nextValue = 1;
setValue((preValue) =>
preValue + nextValue < 100 ? (preValue += nextValue) : 100,
);
progressTimer.current =
timestamp + 100;
}
runAgain.current = timestamp + 100;
}
// batch the animation for the next frame paint
requestIdRef.current = requestAnimationFrame(nextFrame);
}
useEffect(function () {
requestIdRef.current = requestAnimationFrame(nextFrame);
return () => cancelAnimationFrame(requestIdRef.current);
}, []);
return (
<div className="App">
<p>{value}</p>
</div>
);
}
```
Let's explain what is happening here:
* We added a way to keep track of the counter value using the `useState` hook with the `value` and `setValue` variables.
* We also utilized the `useRef` hook to declare three other variables. This ensures they remain unaffected and don't trigger any side effects when updated.
* We initialized the `runAgain` and `progressTimer` `ref` variables with the `performance.now()` method. This initialization captures the current `timestamp` when the page first loaded. It also synchronizes their values with the `timestamp` from the `requestAnimationFrame` `callback` argument.
* The `requestIdRef` variable stores the value the `requestAnimationFrame` method returns.
* We defined the `nextFrame` function as the `callback` for the `requestAnimationFrame` method. This function wraps the counter logic, and the `requestAnimationFrame` recursively invokes it.
* We ensured the conditional code block for `runAgain.current` and `progressTimer.current` executes. This event occurs when they are less than or equal to the current `timestamp` value.
* We updated `runAgain.current` and `progressTimer.current` below the conditional statement code blocks. These updates ensure a smooth repaint after a designated interval.
* Inside a `useEffect` `callback`, we invoked the `requestAnimationFrame` with the `nextFrame` function. We also provided an empty dependency array to the `useEffect` to ensure it runs once.
* Finally, we cleaned up after the initial invocation. In the returned function, ensure to pass `requestIdRef.current` to the `cancelAnimationFrame` method.
But there is a slight bug with this code. Currently, the timed loop doesn't stop once it starts. While this behavior is acceptable in specific scenarios, it defeats our goal. To address this, consider the following:
```jsx
useEffect(
function () {
if (value >= 100) {
cancelAnimationFrame(requestIdRef.current);
}
},
[value],
);
```
The code snippet above shows a `useEffect` keeping track of the progress value. Placing this code below the previous `useEffect` cancels the animation request once completed.
### Extracting the `requestAnimationFrame` Logic into a Custom Hook
The preceding section shows a progress counter implementation with the `requestAnimationFrame` method. Unfortunately, this approach becomes tedious when duplicating the same logic across several components. So, moving the whole logic to a custom hook becomes necessary and helpful. Let us create a reusable hook to encapsulate our progress counter logic:
```jsx
// useProgressLoader.jsx
function useProgressLoader(interval = 2000) {
// Values to update
const [value, setValue] = useState(0);
const runAgain = useRef(performance.now() + 100);
const progressTimer = useRef(performance.now() + 100);
const requestIdRef = useRef(0);
function nextFrame(timestamp) {
if (runAgain.current <= timestamp) {
// Run the animation
if (progressTimer.current <= timestamp) {
// When the native timestamp catches up to the set interval
// animate the element with the current value
const nextValue = Math.floor(Math.random() * 25) + 1;
setValue((prevValue) =>
(prevValue + nextValue < 100 ? (prevValue += nextValue) : 100)
);
// Change to a random interval
progressTimer.current =
timestamp + Math.floor(Math.random() * (interval - 800)) + 500;
}
runAgain.current = timestamp + 100;
}
// batch the animation for the next frame paint
requestIdRef.current = requestAnimationFrame(nextFrame);
}
useEffect(function () {
requestIdRef.current = requestAnimationFrame(nextFrame);
return () => cancelAnimationFrame(requestIdRef.current);
}, []);
useEffect(() => {
if (value >= 100) {
// Stop the animation
cancelAnimationFrame(requestIdRef.current);
}
}, [value]);
return { value };
}
```
The progress logic is almost identical to the previous implementation, with minor changes:
* We made the interval used to update the `progressTimer.current` value dynamic.
* The `progressTimer.current` gets updated with the current `timestamp` and a random interval.
* We ensured the progress increased with random values from 1 to 25.
Based on these improvements, let's build an animated progress loader.
<CTA_Middle_Frameworks />
## Creating Progress Loader Animations
So far, we demonstrated a basic progress counter with our `requestAnimationFrame` setup. Now, let's develop more advanced loader animations, such as:
* A progress bar
* A circular progress indicator
### Implementing a Progress Bar
A circular progress indicator provides visual feedback about an ongoing task. It moves in a circular motion toward its starting position. Let's show this with the code example below:
```jsx
// ProgressBar.jsx
import "./progressbar.css";
const ProgressBar = () => {
const value = 50;
return (
<section className="">
<div
id="progress"
role="progressbar"
aria-valuenow={value}
aria-valuemax={100}
>
<div
style={{ width: value + "%" }}
id="indicator"
aria-label="Progress indicator"
></div>
<p>{value}%</p>
</div>
</section>
);
};
export default ProgressBar;
```
In the code above, we have created a component to encapsulate the progress bar UI logic. We ensured accessibility by setting the `progressbar` value on the `div` tag `role` attribute. We also provided the values for the `aria-valuenow` and `aria-valuemax` attributes. Let's define the CSS properties for a visually appealing progress bar:
```css
/* progressbar.css */
#progress {
height: 2rem;
width: 100%;
position: relative;
display: flex;
align-items: center;
justify-content: center;
}
#progress > p {
font-size: 12px;
position: relative;
z-index: 2;
}
#indicator {
top: 0;
position: absolute;
left: 0;
height: 100%;
background: #3a9a3a;
transition: width 0.4s ease-out;
-moz-transition: width 0.4s ease-out;
-webkit-transition: width 0.4s ease-out;
}
```
In the CSS styles above, we set the width and height of the `#progress` selector. Ensuring the bar is wide enough for the indicator. The CSS `flexbox` values center the label in vertical and horizontal space. To display the `#indicator` selector, we defined its position as absolute. Furthermore, we set the top and left properties to zero and the height to 100%. These values enable the indicator to fit into the bar's dimension. Finally, defining the transition property facilitates a smooth repaint.
The following code renders the progress bar in the app:
```jsx
// App.jsx
import ProgressBar from "./ProgressBar";
export default function App() {
return (
<div className="App">
<ProgressBar />
</div>
);
}
```
For demonstration purposes, we set an initial value of 50. Here is a snapshot of the rendered progress bar:
To animate the bar, let's replace the line that initializes the progress value.
```jsx
// ProgressBar.jsx
import useProgressLoader from "./useProgressLoader";
const ProgressBar = () => {
const { value } = useProgressLoader();
return (
{ /* Progress bar UI JSX */ }
);
};
```
In the code above, we used the value returned by the `useProgressLoader` hook instead. This value ensures the rendered horizontal displays a visual progress.
Below is a visual result of the horizontal progress bar in motion:
### Creating a Circular Progress Indicator
A circular progress indicator is a UI element that provides visual feedback to convey the idea of an ongoing task or process by moving in a circular motion toward its starting position. Let's demonstrate this with the code example below:
```jsx
// CircularProgressLoader.jsx
import "./circular-progress-loader.css";
import useProgressLoader from "./useProgressLoader";
const CircularProgressLoader = () => {
const { value } = useProgressLoader();
return (
<section className="circle-wrapper">
<div
className="circular-progress"
role="progressbar"
aria-valuemin={0}
aria-valuenow={value}
aria-valuemax={100}
style={{
background: `conic-gradient(#F4A443 ${(360 / 100) * value}deg, #F7F8F7 0deg)`,
}}
>
<p aria-label="Generate progress value" className="progress-label">
{value}%
</p>
</div>
</section>
);
};
export default CircularProgressLoader;
```
In the code snippet above, we employed three accessible elements. The innermost element displays the current fill percent. Furthermore, we applied the CSS conic-gradient background value to create a color-filled area. Finally, incorporating the value from the `useProgressLoader` hook, animated the loader. Let's define the CSS properties for a circular area:
```css
/* circular-progress-loader.css */
.circular-progress {
position: relative;
display: flex;
justify-content: center;
align-items: center;
height: 300px;
width: 300px;
border-radius: 50%;
}
.circular-progress .progress-label {
position: absolute;
z-index: 2;
}
```
To create a circular shape, we set equal width and height and `border-radius` of 50%. Defining the `flex-box` values centers the label in the horizontal and vertical space.
The following code displays the progress indicator:
```jsx
// App.jsx
import CircularProgressLoader from "./CircularProgressLoader";
export default function App() {
return (
<div className="App">
<CircularProgressLoader />
</div>
);
}
```
Below is a visual illustration of the circular progress indicator in motion:
## Final Thoughts
This article explored how the `requestAnimationFrame` method surpasses conventional means. We also discussed its role and benefits in web animation. Furthermore, we ensured modularity and reusability of animation logic with a custom hook.
As a powerful tool, the `requestAnimationFrame` method offers several benefits and use cases. Understanding its proper usage is crucial in optimizing animations and enhancing user experience.

III. CircleCI vs. Jenkins: A Head-to-Head Comparison
The central debate between CircleCI and Jenkins is not one that can be resolved through a single winner-takes-all declaration. Instead, let’s scrutinize the key points of distinction to understand how each fares in certain areas.
Installation and Setup
CircleCI: CircleCI is a cloud-based solution that eliminates the need for installation. Simply connect CircleCI to your version control system (GitHub/Bitbucket), and it automatically detects and builds your projects. This streamlined setup process reduces complexity and saves time.
[Jenkins](https://www.pcloudy.com/blogs/using-jenkins-as-your-go-to-ci-cd-tool/): Jenkins is a self-hosted solution that requires installation on a server. While it offers the flexibility to run on a variety of operating systems, setup can be more complex and time-consuming. However, Jenkins offers the advantage of being highly customizable and adaptable to specific infrastructure requirements.
Configuration and Maintenance
CircleCI: Projects in CircleCI are configured through a YAML file, known as “circle.yaml.” This file defines the tasks and workflows, making it easier to manage and maintain. CircleCI’s automatic parallel task configuration further simplifies the setup process.
Jenkins: Jenkins requires extensive configuration through its web-based interface. However, its “Pipeline as Code” feature allows you to define and manage workflows using code, reducing the manual configuration effort. This flexibility enables highly customized CI/CD pipelines tailored to specific project needs.
Scalability and Performance
CircleCI: As a cloud-based service, CircleCI scales seamlessly and offers excellent performance. Builds are automatically balanced and queued, ensuring efficient utilization of resources. This scalability is particularly advantageous for teams working on projects with fluctuating build demands.
Jenkins: Jenkins can scale, but it requires manual configuration of additional nodes to distribute the workload. Performance depends on the capacity and configuration of the server infrastructure. While Jenkins can handle large-scale projects with the right setup, it may require more maintenance and monitoring to ensure optimal performance.
Integration Ecosystem
[CircleCI](https://www.pcloudy.com/blogs/pcloudy-and-circleci-reinventing-test-automation-with-integrated-ci-cd-pipeline/): While CircleCI has a growing ecosystem of integrations, it may not have the same breadth as Jenkins due to its relative newness. However, it provides seamless integration with popular version control systems like GitHub and Bitbucket, as well as a range of other developer tools and services.
Jenkins: Jenkins has been in the market for a longer time and boasts a vast ecosystem of plugins and integrations. It supports a wide range of tools and technologies, making it a versatile choice for integrating with various systems. The extensive plugin ecosystem allows for easy integration with popular tools, services, and infrastructure providers.

Jenkins: Jenkins is renowned for its flexibility and customization options. With its vast plugin ecosystem and the ability to define pipelines as code, Jenkins allows for highly tailored CI/CD workflows. This flexibility makes it a popular choice for organizations with complex requirements.
In addition to the above aspects, let’s summarize the other key differences between CircleCI and Jenkins:
Aspect Jenkins CircleCI
Build Management Builds managed via UI; configurations stored in files or Jenkins database. Less convenient for sharing configuration data. Tasks defined in a single YAML document (circle.yaml), easily shareable like other source code repositories.
Server Requirements Requires dedicated server and manual maintenance. Operates on a cloud-based platform, automatically executing code in fresh containers. Requires less maintenance.
Debugging Debugging process can be complex, often requiring manual DevOps testing. Offers simple debugging with SSH and [automated DevOps testing](https://www.pcloudy.com/mobile-and-web-devops/) features.
User Interface UI can be slower and less responsive due to local server dependency and reliance on numerous plugins. Provides a continually improving UI with built-in support, enhancing speed and responsiveness.
Docker Workflow No inherent support for Docker workflows; developers need to install separately. Built-in Docker support via the services section of the circle.yaml script.
Parallel Builds Supports parallel tasks through multi-threading. Offers built-in support for parallelism, configurable through developer settings.
Data Security Ensures security of confidential files and encrypted data through plugins and credentials. Provides limited settings for encrypted files, with most data accessible to developers.
After evaluating these categories, CircleCI and Jenkins demonstrate distinct strengths and considerations. CircleCI excels in its cloud-based deployment, simplified configuration, and scalability. On the other hand, Jenkins stands out for its extensive plugin ecosystem, customization capabilities, and the support of a vibrant community.
Ultimately, the choice between CircleCI and Jenkins depends on various factors such as project requirements, team expertise, scalability needs, and budget considerations. It’s recommended to thoroughly evaluate these factors and potentially conduct a trial or proof of concept to determine which tool aligns best with your organization’s needs.
Understanding pCloudy: Uniting CI/CD Tools with Cloud-Based Test Automation Platform
Having analyzed the contrasts between CircleCI and Jenkins, let’s delve into how to integrate a [test automation tool](https://www.pcloudy.com/rapid-automation-testing/) with pCloudy for DevOps testing.
DevOps testing, or Continuous Testing, is a blend of CI/CD and test automation. The goal is to test every build, whether it’s committed, integrated, deployed to a new environment, or finally launched.

Buckle up, design enthusiasts! We're embarking on a thrilling adventure to explore the boundless creative potential of [Atropos.js](https://atroposjs.com/) in web design. The purpose is to showcase the captivating possibilities offered by this library, using a popular movie (Game of Thrones) character gallery sourced from [ThronesAPI](https://rb.gy/4txpsn) as our canvas. Join us on this journey of innovation and inspiration.
## Understanding Atropos.js
[Atropos.js](https://atroposjs.com/) is a lightweight and versatile JavaScript library that enhances web design with captivating scroll-based animations. Its features include parallax effects, scroll-triggered animations, and seamless integration with popular frameworks like React and Vue.js.
With this library, developers can effortlessly create immersive user experiences, captivating audiences with dynamic scrolling effects. Its capabilities empower web designers to craft visually stunning and engaging websites that leave a lasting impression.
## Importance of Atropos.js to Web Developers

* Its design flexibility makes it easy to use for areas of your project other than scroll galleries, like interactive menus, eye-catching portfolios, and more!
* Developers can quickly add dynamic components such as parallax effects, enticing scroll-triggered animations, and other elements to their websites with this library, which improves the site's visual appeal and makes it more memorable.
## Building a Scrolled-Based Gallery with Atropos.js
To develop an engaging scroll-based gallery, the project uses [Axios](https://axios-http.com/docs/intro), React, Atropos.js, and ThronesAPI from a public source. This entails seamlessly integrating different technologies to accomplish the project's goals and provide an enjoyable user experience.
[ThronesAPI](https://rb.gy/4txpsn) offers access to an extensive database, making it an indispensable tool for gathering information about movie characters. Our project uses this API to dynamically present these characters in an eye-catching gallery, showcasing the creative potential of this library in web design.
## Setting Up the Project Environment
To begin the project, we will establish it with [Vite](https://vitejs.dev/guide/). Enter the following command to accomplish this:
```javascript
npm create vite@latest
```
Give your project a name and run the project. Once done, install the Atropos.js package as it is vital for this project. To do this, enter the command below:
```javascript
npm i atropos
```
Once the package has been installed successfully, the next thing to do is import/add the package into your project. To import the features of this library, all you need to do is add the link below to your stylesheet if you're using Vanilla JavaScript.
```javascript
<link rel="stylesheet" href="path/to/atropos.css" />
```
For this project, we will be using React. You can easily head into your `App.js` file and import this library's functionalities by inputting the command.
```javascript
import "atropos/css";
```
Another package that would be crucial for this project would be Axios. We will use this package to make API calls to ThronesAPI to extract its data (the movie characters) and display them in our scroll gallery. To install this package simply type in the command.
```javascript
npm i axios
```
Once installed, also ensure it is imported into your `App.js` file to add its functionalities as seen below.
```javascript
import axios from "axios"
```
<CTA_Middle_Design />
## Implementing the Scrolled-Based Gallery
We can now move on to obtaining the data from the ThronesAPI, which consists of the movie characters, to build our gallery.
Create a state variable, give it a name, and set it to accept an array as input inside the scroll section of our program. This keeps all of the character data obtained from the ThronesAPI in an array for convenience.
Next up, we include a `useEffect` hook, and within this hook, we make an API call to fetch the required data for this project using Axios, as seen below:
```javascript
const ScrollSection = () => {
const [actors, setActors] = useState([]);
// Make a GET request
useEffect(() => {
const fetchData = async () => {
try {
const response = await axios.get(
"https://thronesapi.com/api/v2/Characters",
);
setActors(response.data);
} catch (error) {
console.error(error);
}
};
fetchData();
}, []);
console.log(actors);
};
```
The data is then stored in a variable called `response`, as seen above. To extract the data from the `response` variable, we store it in the state variable created earlier and then quickly run a check to make sure everything works properly.
Once confirmed, the next step would be to display character data and wrap this data with Atropos.js.
To begin, head into the `return` statement of the file, and inside the `div` element, map through the content of the state variable you created earlier that holds the `response` data. Once done, add a `div` with a `key` (we will use the `IDs` from the dataset). Then, inside the `div` element, we can display the character data needed for the gallery.
```javascript
return (
<div className="grid grid-cols-3 gap-4">
{/* */}
{actors.map((casts) => (
<div
key={casts.id}
className="rounded overflow-hidden w-81 h-95 shadow-md mb-5 text-white"
>
<img src={casts.imageUrl} className="w-full h-60 object-cover" />
<div className="p-3">
<p className="font-bold text-2xl">{casts.fullName}</p>
<p className="block text-grey-500 text-xl">{casts.title}</p>
</div>
</div>
))}
</div>
);
```
For this project, we will present only the character's name, title, and picture as it appears above.
Now we will need to employ the services of this library in the project. To do this, simply wrap the displayed data in an `Atropos` element, and in this element, we can add some functionalities.
```javascript
<Atropos
activeOffset={40}
shadowScale={1.05}
onEnter={() => console.log("Enter")}
onLeave={() => console.log("Leave")}
onRotate={(x, y) => console.log("Rotate", x, y)}
duration={100}
highlight={true}
>
<img
src={casts.imageUrl}
className="w-full h-60 object-cover"
data-atropos-offset="5"
/>
<div className="p-3" data-atropos-opacity="1;0">
<p className="font-bold text-2xl text-[#00df9a]">{casts.fullName}</p>
<p className="block text-grey-500">{casts.title}</p>
</div>
</Atropos>;
```
Some of these library attributes were used to enhance the gallery as seen above, they include:
* `activeOffset`: Indicates the offset (in pixels) of the element's activation from the viewport boundary.
* `shadowScale`: Modifies the size of the image's applied shadow effect.
* A callback function called `onEnter` is activated when an element enters the viewport.
* The callback method `onLeave` is activated when an element exits the viewport.
* `onRotate`: When the user rotates the element, a callback function is initiated.
* `duration`: Indicates how long the transition effect will last (in milliseconds).
* `highlight`: Defines whether the active element should be highlighted.
Additionally, a `data-atropos-opacity` attribute was added to the character's details, controlling the opacity of each text so that it fades out as the user scrolls down. As can be seen above, a `data-atropos-offset` attribute was added to the `img` element. This sets a slight offset for the image to become active when the user scrolls.
This library provides these attributes, amongst others. They can be seen in the [documentation](https://https://atroposjs.com/docs/react#component-props) and explored. As demonstrated above, This library's features and attributes take effect when the images and character data are hovered over, resulting in an eye-catching display in the image gallery.
## Conclusion
As seen, this project beautifully showcases how this library can breathe life into web design. We've crafted a captivating scroll-based gallery of movie characters by leveraging its features. This journey highlights the exciting ways this library enhances user experiences, bringing creativity and dynamism to web design.

One... | 0 | 2024-06-15T14:02:45 | https://raajaryan.tech/how-to-improve-user-experience-with-image-previews-a-step-by-step-guide | javascript, beginners, tutorial, opensource | In today's digital age, providing a seamless user experience is crucial for web developers. One effective way to enhance user interaction is by allowing users to preview images before uploading them. This feature not only improves the user experience but also reduces errors, ensuring that users select the correct files. In this blog post, we'll walk you through a simple implementation of an image preview feature using HTML, JavaScript, and the FileReader API.
#### Why Image Previews Matter
Image previews offer several benefits:
- **Immediate Feedback**: Users can see the image they are about to upload, ensuring it's the correct file.
- **Improved UX**: A more interactive and visually appealing interface.
- **Error Reduction**: Users can catch mistakes before uploading the wrong image.
Let's dive into the code to implement this feature.
#### Step-by-Step Guide
1. **HTML Structure**
Start with a basic HTML structure that includes a file input element and a container for displaying the images.
``` Html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Image Upload with Fixed Upload Section</title>
<style>
/* CSS styles will be discussed later */
</style>
</head>
<body>
<div class="container">
<h1>Image Upload with Fixed Upload Section</h1>
<div class="file-upload">
<input type="file" name="file" id="fileupload" class="file-input" accept="image/*">
<label for="fileupload" class="file-label">Choose Image</label>
</div>
<div class="image-preview-container">
<ul id="imgaestore" class="image-preview-list"></ul>
</div>
</div>
<script>
// JavaScript functionality will be discussed later
</script>
</body>
</html>
```
2. **Styling the Interface with CSS**
Next, let's apply CSS to achieve a clean and modern design for our upload section and image previews:
```css
body {
font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
background-color: #f8f9fa;
margin: 0;
padding: 0;
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
}
.container {
max-width: 600px;
background-color: #fff;
padding: 20px;
border-radius: 8px;
box-shadow: 0 4px 8px rgba(0,0,0,0.1);
position: relative;
}
h1 {
font-size: 24px;
margin-bottom: 20px;
color: #333;
text-align: center;
}
.file-upload {
position: sticky;
top: 0;
background-color: #fff;
z-index: 1000;
padding: 10px;
display: flex;
justify-content: space-between;
align-items: center;
margin-bottom: 20px;
border-bottom: 1px solid #ccc;
}
.file-input {
display: none;
}
.file-label {
display: inline-block;
padding: 10px 15px;
background-color: #007bff;
color: #fff;
border-radius: 4px;
cursor: pointer;
transition: background-color 0.3s ease;
}
.file-label:hover {
background-color: #0056b3;
}
.image-preview-container {
max-height: 400px; /* Adjust the maximum height as needed */
overflow-y: auto;
}
.image-preview-list {
list-style-type: none;
padding: 0;
margin: 0;
}
.image-preview-item {
margin-bottom: 10px;
padding: 10px;
background-color: #fff;
box-shadow: 0 2px 4px rgba(0,0,0,0.1);
border-radius: 4px;
display: flex;
align-items: center;
}
.preview-image {
max-width: 100px;
max-height: 100px;
margin-right: 10px;
border-radius: 4px;
}
.image-info {
flex: 1;
}
.image-info p {
margin: 5px 0;
color: #555;
}
```
3. **JavaScript for Image Preview**
Use JavaScript to handle the file input change event and display the selected image.
``` html
<script>
const fileupload = document.getElementById("fileupload");
const imagePreviewList = document.getElementById("imgaestore");
fileupload.addEventListener("change", showimgaefile);
function showimgaefile() {
const files = fileupload.files;
for (let i = 0; i < files.length; i++) {
const file = files[i];
if (file.type.startsWith('image/')) {
const reader = new FileReader();
reader.onload = function(e) {
const img = document.createElement("img");
img.src = e.target.result;
img.alt = "Uploaded Image";
img.classList.add("preview-image");
const imageInfo = document.createElement("div");
imageInfo.classList.add("image-info");
imageInfo.innerHTML = `
<p><strong>File Name:</strong> ${file.name}</p>
<p><strong>File Size:</strong> ${(file.size / 1024).toFixed(2)} KB</p>
`;
const li = document.createElement("li");
li.classList.add("image-preview-item");
li.appendChild(img);
li.appendChild(imageInfo);
imagePreviewList.appendChild(li);
};
reader.readAsDataURL(file);
} else {
alert("Please select an image file.");
}
}
// Clear input value after file selection
this.value = null;
}
</script>
```
#### Explanation
- **Event Listener**: We add a `change` event listener to the file input element. This event triggers when the user selects a file.
- **FileReader API**: This API is used to read the content of the file. We use `readAsDataURL` to read the file and convert it into a Data URL.
- **Creating Image Element**: Once the file is read, we create an `img` element and set its `src` attribute to the Data URL obtained from the FileReader.
- **Appending Elements**: Finally, we create a `li` element, append the `img` element to it, and then append the `li` to the `ul` element.
#### Conclusion
Implementing an image preview feature is a simple yet effective way to enhance user experience on your website. By providing immediate visual feedback, you can improve user satisfaction and reduce errors. This guide provides a basic implementation, but there are many ways to expand and customize this feature to fit your specific needs.
Start integrating this feature into your projects and see the difference it makes in user engagement and satisfaction. Happy coding!

Have you ever looked at a blank white screen while waiting for a page to load? Or you've observed a spinning circle for what seemed like an eternity. In today's web age, waiting for content to load can be frustrating.
To address this, developers devised two key strategies: skeleton screens and loading screens. Understanding the differences between these two strategies is crucial for delivering an excellent user experience (UX).
In this article, we'll closely examine the skeleton and loading screens. We'll discuss the key differences between these two techniques and where they fit in. By the end, you'll be able to select the most appropriate technique for the job, keeping your users satisfied and engaged.
## Problems of Poor Loading Time
Poor loading times can significantly negatively impact your website or app in several ways. They can increase your website's return rates; many users will simply click away and go to a competitor's site, leading to a significant loss of potential customers or visitors.
Also, users may think your app or website is out-of-date, careless, or unprofessional. This can damage your brand reputation and lead to negative reviews.
Page speed is one ranking criterion that Google and other search engines consider. Websites with loading problems usually have a lower search engine ranking, making it harder for potential customers to find you.
## Understanding Skeleton Screens
A Skeleton Screen is a temporary placeholder in web design that offers users a glimpse of the content layout before the actual content loads in the background. It is crucial in optimizing the user experience by mitigating the frustration associated with content loading delays.
Skeleton screens are visual representations of content's layout and structure that appear in place of actual content while the data is being fetched or loaded. They often feature light gray squares, rectangles, circles, or [monochromes](https://en.wikipedia.org/wiki/Monochrome) as a visual representation of where each piece of content will appear.
Its primary objective is to provide users with a sense of progress and continuity, thereby minimizing perceived loading time and enhancing overall satisfaction.
The image above shows a dashboard that is loading due to a weak network connection or a huge amount of data being retrieved from the server.
Imagine walking into an event arena and seeing chairs arranged where people are meant to sit before their arrival. This relates to a skeleton screen.
This approach offers the following benefits:
* Improved User Engagement: By showing the layout upfront, users can anticipate the content and stay focused on the app or website. This prevents them from navigating away due to the delay.
* Seamless Transition: After loading, each piece of content appears in the exact position. The size, shape, and type of content are maintained. If it were a circle picture, it would appear as such.
* Awareness: Users can see where content will appear, reducing the feeling of emptiness during loading and thus creating a sense of awareness.
## Types of Skeleton Screens
We will examine three types of skeleton screens based on how they behave during loading and before content appears.
### Static Placeholder
A static placeholder represents the absence of the actual element. It occupies the space where the final content will eventually appear.
Static placeholders are the most basic form of placeholder used in skeleton screens. They lack animation and provide a basic structure for the data being fetched.
The image above shows a static placeholder without any form of animation, which imitates the layout and structure of the actual content pending when loading is completed.
### Pulse Placeholder
This refers to the animation applied to a skeleton screen that simulates a pulsing or flickering effect. This animation helps grab the user's attention and indicates that the content is still loading.
Pulse placeholders are convenient when the loading time is unpredictable, or the content loads all at once.
In a pulse placeholder, as seen in the illustration above, there is a low transition in the opacity of the screen. The opacity reduces and fills slowly during the loading process. The content loading progress is stimulated by a pulsating effect.
### Waving Placeholders
A waving placeholder skeleton screen is another animation technique used to breathe life into skeleton screens. Unlike the pulsating effect, which fades elements in and out, a waving animation creates a more dynamic visualization.
Waving placeholders are often used when content loads progressively, such as a long list of items or a large image. The waving animation suggests the content is filling in section by section.
This type of skeleton screen has a gradient and/or shadow that moves horizontally across the screen's content.
## Best Practices for Implementing Skeleton Screens
Skeleton screens are implemented using various techniques, such as CSS animations, libraries, and frameworks. It is critical to follow best practices in design and integration to maintain consistency and clarity in the visual representation of content placeholders. These guidelines include:
* Consistency: To avoid breaking trust, there should be no change in position, size, or type of content on the user interface after the content is done loading.
* Control animation speed: Always go for fast motions since slow motions give the perception of slow loading.
* Avoid overuse of skeleton screens: As contents start loading, the placeholders should be replaced progressively. The screens should not be left on for too long.
* Test across devices: Ensure your skeleton screens function properly across various devices such as desktops, mobile, and tablets.
* Use error message: Have a clear error message in place if the data fails to be fetched. This technique allows users to retry or take alternative actions.
* Accessibility: Ensure your skeleton screens are accessible to users with visual impairments by using appropriate color contrast and providing alternative text descriptions for placeholders.

## Understanding Loading Screens
Loading screens are interface elements displayed to users during the loading process. They are graphical elements that inform users that their requests are being processed.
Loading screens may include a progress bar, spinners, or a simple message informing users that data is being fetched.
There are various ways that a well-designed loading screen can improve the user experience. These approaches include:
* Communication: Loading screens pass information that the system is working to fetch data, thus preventing users from wondering if there is a breakdown in the system. Imagine flipping a light switch, but there is a delay before the room illuminates. A loading screen acts like a sign on the switch saying, "Hold on, light is coming!"
* Manage Expectations: Loading screens give users an idea of how long they have to wait. This could be a simple progress bar that fills up as content loads.
* Maintain Engagement: Loading screens contain basic animations like a spinning circle or informative messages, which can keep users engaged.
## Types of Loading Screens
Loading screens come in various types, each with its description. Here is a breakdown of the common types.
### Static Screens
Static screens are the simplest form of loading screens. They mostly display a logo or generic message like "Loading." They are easy to implement. An example is opening a new app and seeing the app's logo displayed while the contents load in the background.
Static screens are often used in cases where contents load almost instantaneously or in simple apps and websites with predictable loading times.
The above image is an example of a static screen with the generic message "loading," informing the user that the server is fetching data or loading responses.
### Progress Bars
They are typically like bars that fill up as the contents load. They are sometimes accompanied by a percentage indicator. For example, when downloading a log file, a bar shows the percentage of the file downloaded and the estimated time remaining.
Progress bars provide specific details about the loading process. Users can know how long they'll have to wait or what percentage is complete.
The image above displays the progress of data loading. As soon as the movement fills the bar, loading will be completed.
**Progress bar with percentage indicator**:
Some progress bars are accompanied by a number showing the task's completion percentage. It's usually displayed alongside the progress bar itself.
The above image shows a progress bar accompanied by a percentage indicator counting from 1% to 100% to show the rate at which data is loading.
### Spinners
Spinners are animated elements that spin or rotate continuously, indicating ongoing background activity. An example is clicking a link on a website, and a small rotating circle appears next to the link while the new page loads.
The illustration above is an example of a loading spinner; it shows pulsating dots in continuous circular movement.
## Best Practices for Implementing Loading Screens
Proper implementation of loading screens can significantly impact user experience. Here are some key best practices to consider.
* Clear message: The message conveyed by loading screens should be clear and easy to understand.
* Engage users: Keep users occupied by using subtle animations or informative messages to keep them engaged during the wait.
* Brand consistency: Incorporate your logo or color scheme to maintain brand consistency and a cohesive user experience.
* Provide alternative options: Put in place options for users to retry, troubleshoot, or contact support so that in a situation where data fails to load, they will not be left hanging.
* Screen Compatibility: Ensure the design elements and texts can easily be read on a compact screen.
* Offer snippets of tips: You can offer users snippets of information, tips, or facts while they wait for the load.
## Comparisons Between Skeleton and Loading Screens
Both the skeleton and loading screens appear when you wait for content to load to create a seamless user experience, but each has a different approach impacting the brand and target audience.
This session will expose some contrasting features between skeleton screens and loading screens.
| Skeleton Screens | Loading Screens |
| ------------------------------------------------------------------------------------------------------------------------------------------- |:------------------------------------------------------------------------------------------------------------------------ |
| Use skeleton screens when more than one element is loading at the same time | Use loading screens when content loading times can vary significantly due to factors like internet speed or severe load. |
| Avoid skeleton screens when it comes to uploads, downloads, and file conversion. | Progress bar is a better option when it has to do uploads, downloads, and file conversion |
| Skeleton screens are best considered for minimizing perceived wait time | Loading screens are prioritized for providing accurate loading communication |
| Skeleton screens provide limited information about specific loading progress | Loading screens convey adequate information about the loading process |
| Skeleton screens act like ghosts of the final content, showing an empty layout that gradually fills in with the actual content as it loads. | Loading screens are temporary screens that display as contents fetch in the background. |
| Use skeleton screens when websites and apps have a lot of traffic. | Use loading screens for longer applications with potentially longer loading times. |
| Use skeleton screens when loading data takes more than three seconds | Use loading screens if your app or website does not offer alternative functionalities while content loads. |
The table above discusses the differences between the skeleton and loading screen, as well as when to use and not use each.
## Conclusion
Both skeleton screens and loading screens play a crucial role in the user experience during content loading times. They bridge the gap between user interaction and content delivery, but they achieve this in distinct ways, impacting user perception differently.
By understanding the concepts, benefits, use cases, and limitations of each, as covered in this article, they can be effectively adopted to improve the overall user experience.

I usually code for a little over 10 hours a day, so I am expecting today to be a little boring. I intend to compensate for that by playing games on [Steam](https://steamcommunity.com/id/callmeadiah/) (not code related), by watching [Gene Roddenberry's Andromenda](https://en.wikipedia.org/wiki/Andromeda_(TV_series)) on Pluto TV and by reading further in my book on [the power of feelings](https://a.co/d/1Tvjoo4).
15 min - [Codecademy](https://www.codecademy.com/profiles/AnitaOlsen). The "Learn Intermediate Python 3: Object-Oriented Programming" course: I started over on the course and watched a video on Object-Oriented Programming, I defined a class and a class variable, and I ticked off a box (learning to code on the platform for at least 15 min a day is the minimum required amount to qualify for Codecademy's [30-Days Challenge](https://www.codecademy.com/30daychallenge)).
A little over 10 min - [CodeCombat](https://codecombat.com/user/anitaolsen). I coded, ran the code and won two coding matches + I ran a code for a singleplayer level which I technically completed the other day, so today I just ran it so it could get registered for today as I do my best to run a code a day and it is nice to make sure I got code to run for each day.
_I am afraid I can not show you my code for the multiplayer matches because if I do, somebody might take my code, improve it and beat me. I risk waking up one morning to 100% losses on my matches!_ 😱
6 min - [W3Schools](https://www.w3profile.com/anitaolsen). The HTML course: There was a page to read on HTML formatting + a HTML formatting exercise quiz to take which I did twice as I wanted to achieve the full score.
My start page - All checked! ✨
<center><mark>Total coding time: ca. 31 minutes!</mark></center>
**How my day has been like so far:**
-I woke up a little before 6 am.
-I completed all my coding dailies way before noon as usual.
-I started writing this post.
-It was getting close to 9 am which is my breakfast meal time, so I went to my local bakery for a large closed whole grain sandwich made especially for me ♡
-I overate at breakfast, became sleepy and went back to bed for a nap.
-I dreamt about [Neopets](https://www.neopets.com/) and its creator. (Neopets is an online world were you adopt pets, go on adventures, play minigames, go shopping, join guilds, write in forums, participate in contests and etc. I used to be very active there and last year [I got picked to beta-test an app with them](https://play.google.com/store/apps/details?id=com.neopets.islandbuilders).) I dreamed that we were hanging out and that he needed help with his site. I suggested DEV for him so that perhaps he could find somebody on here to help him with his site.
-I had slept for 2 hours until the alarm I had sat to remind me to turn my washing machine on at the perfect hour (for the lowest priced electricity hour per watt), went off, brutally waking me up from my slumber.
-I started my washing machine and of course there were some clothing I forgot to put in it.
-I read a few pages from my book.
-I had the last of my large sandwich for lunch at 1 pm.
-My washing machine was finished so I took out my laundry and hung it to dry on a rack in my second bedroom.
-I was in need of a popsickle.
I will reward myself with another popsickle after I have completed this post, then I plan to have my afternoon tea at 4 pm with some nut bars and grapes with my herbal tea, then I plan on playing some games, watching Andromeda and read more from my book. I also plan to have fish balls for dinner at 8 pm, then it will be goodnight, sleeping for 7 hours and repeat! ✨

In the realm of [application testing](https://www.pcloudy.com/blogs/how-to-accelerate-app-testing-using-continuous-testing-cloud/), the ability to monitor and control the execution of your test suite is fundamental to the successful delivery of high-quality software. These essential strategies allow managers to gauge progress and make real-time adjustments to maximize efficiency and accuracy. In this comprehensive guide, we’ll delve into the definitions, mechanisms, and benefits of [test monitoring](https://www.pcloudy.com/blogs/role-of-continuous-monitoring-in-devops-pipeline/) and test control. We’ll also explore how these methodologies can enhance your testing approach, improve communication within your team, and ultimately lead to better software outcomes.
What is Test Monitoring?
At its core, test monitoring is a process in which the execution of testing activities is tracked, measured, and assessed. This continuous review allows testing professionals to gauge current progress, identify trends through analysis of testing metrics, estimate future trajectories based on test data, and provide timely feedback to all relevant parties. Test monitoring data can be collected both manually or through automated tools and is vital for assessing exit criteria like coverage.
Moreover, test monitoring is a proactive and iterative process, involving frequent reviews to guarantee that targets are met at every stage of the testing lifecycle. By comparing the current state of testing activities to the anticipated goal, test monitoring provides valuable insights into the effectiveness of the process. This feedback loop enables teams to identify potential issues early, ensuring more accurate and efficient testing outcomes.
What does test monitoring involve?
Test monitoring encompasses several activities that provide valuable feedback on the status of the test process. These activities include:
Updating the test goals achieved so far: This involves continuously monitoring the progress towards the predefined testing goals.
[Identifying and tracking relevant test data](https://www.pcloudy.com/how-to-measure-the-success-of-end-to-end-testing/): Test data forms the backbone of any monitoring activity. By identifying and tracking relevant data, teams can make informed decisions and accurate predictions.
Planning and projecting future actions: Using the data and trends observed, teams can create an action plan for the remainder of the test process.
Communicating status to relevant parties: Keeping stakeholders informed about the progress of the testing process is crucial to ensure alignment with the overall project objectives.
Key Metrics in Test Monitoring?
Test monitoring relies on a collection of key metrics to measure progress and inform decision-making. Commonly tracked metrics include:
Test case execution metrics: These metrics detail the number of test cases that have been executed, along with their outcomes (pass, fail, blocked, etc.).
Test preparation metrics: These metrics monitor the progress of test case preparation and test environment setup, highlighting potential delays or bottlenecks.
Defect metrics: These include the number of defects discovered, their severity, the rate of discovery, and the rate of resolution.
[Test Coverage metrics](https://www.pcloudy.com/how-to-analyze-data-to-predict-your-optimum-device-test-coverage/): These metrics measure how much of the application or system under test has been covered by the test cases.
Test project cost: This includes the cost of resources, tools, and time spent in testing, as well as the potential cost of not discovering a defect.
Requirement Tracking: This ensures that each requirement has corresponding test cases and that all have been executed.
Consumption of Resources: This includes the time and human resources consumed by the project, and helps in planning and allocation of resources.
When to collect data for Test Monitoring?
The frequency and method of data collection in test monitoring depend largely on the nature and timeline of your project. In a project due to be delivered in a month, weekly data collection might be sufficient. In complex or critical projects, however, more frequent updates may be necessary to identify and respond to issues quickly.
Test data can be collected manually, by individual testers, or automatically using test management tools. Regardless of the method, ensuring accurate and timely data collection is paramount. Clear guidelines should be set for what data needs to be collected, by whom, when, and how often.
How to evaluate progress through collected data?
To accurately gauge progress, it’s beneficial to establish an evaluation plan at the beginning of the project. This plan should outline the criteria against which progress will be assessed, providing clarity for all involved.
Progress can typically be measured by comparing planned versus actual progress, and by evaluating project performance against predefined criteria. For instance, if the actual effort spent on testing exceeds the projected effort, it can be inferred that the project is progressing.
Importance of Test Monitoring:
Let’s consider a scenario to understand the significance of test monitoring. Suppose that after initial estimation and planning, the team commits to certain milestones and deadlines. Due to an unforeseen setback, the project gets delayed, causing missed milestones and deadlines. As a result, the project fails, and the client is lost.
This example illustrates that even with meticulous planning, unexpected issues can arise. Test monitoring serves as an essential early warning system to identify such deviations, allowing teams to intervene and correct the course as soon as possible.
Other benefits of test monitoring include providing a transparent view of the project status to management, enabling resource and budget adjustments as needed, and preventing significant problems by identifying and addressing minor issues early.
What is Test Control?
While test monitoring offers a clear view of the current state of testing activities, test control enables teams to take corrective actions based on the insights gained from monitoring. Essentially, test control is the process of managing and adjusting the ongoing testing activities to improve project efficiency and quality.
The test control process is initiated once the test plan is in place. A well-defined testing schedule and monitoring framework are prerequisites for effective test control. This ensures that the Test Manager can track the progress of testing activities and resources used against the plan, making adjustments as required.
Checklist for Test Control Activities
To manage and monitor your test control activities, consider the following checklist:
Review and analyze the current state of the test cycle.
Document the progress of the test cycle, including coverage and exit criteria.
Identify potential risks and develop matrices associated with those risks.
Implement corrective measures and decisions based on the data and analysis.
Why do you need Test Control?
In software development projects, it’s common for teams to encounter unexpected challenges that can hinder progress towards project deadlines. These challenges might include discrepancies in software functionality that require additional time to fix, changes in requirements and specifications based on stakeholder feedback, and unforeseen circumstances that cause delays.
In such situations, test control activities become crucial to manage these changes effectively and maintain the quality of the software.
Executing Test Control activities
The following sequential actions are fundamental to the test control process:
Reviewing and analyzing the current [state of the test cycle](https://www.pcloudy.com/blogs/all-you-need-to-know-about-automation-testing-life-cycle/): This includes the number of tests executed, the severity of the defects, the coverage of the test cases, and the number of tests passed or failed.
Observing and documenting the progress of the test cycle: Keeping the development team informed about the test status, including coverage and exit criteria, is crucial.
Identifying risks and creating associated matrices: Proactively identifying potential risks and preparing to address them helps minimize project delays and defects.
Taking corrective actions: Based on the data analysis, the team can implement corrective measures to stay on track and achieve the desired result.
These actions help the team adapt to the evolving needs of the project and ensure the testing process aligns with the project goals.
Corrective Measures in Test Control
Based on the insights gained from test monitoring reports, teams can implement several corrective measures:
Prioritizing testing efforts: Based on the criticality of the defects and areas of the application, the team can prioritize testing efforts for maximum impact.
Revising testing schedules: If testing activities are not progressing as per the planned schedule, it may be necessary to revise the timeline.
Adjusting resource allocation: If certain testing activities require more attention or manpower, resource allocation may need to be adjusted accordingly.
Changing test scope: If test coverage is not adequate or if new requirements are introduced, the test scope may need to be adjusted.
pCloudy: Elevating Test Monitoring and Control through Real Devices
In the vast realm of testing operations, a cornerstone principle resonates with undeniable clarity – all tests must be performed on real devices. This mandate is driven by the necessity for real user conditions, which ultimately infuse credibility and accuracy into Test Monitoring and Test Control. Using emulators or simulators for testing purposes, while valuable in certain scenarios, can’t replicate the precise environment that real devices offer. Hence, they invariably fall short in providing a comprehensive representation of test results. As a result, the accuracy of the Test Monitoring process might be compromised, leading to a ripple effect where the ensuing Test Control activities might not be appropriately adjusted to enhance the test cycle’s overall productivity.
Harnessing the Power of Real Device Cloud Testing
Regardless of the nature of testing, be it manual or [automated Selenium testing](https://www.pcloudy.com/blogs/understanding-selenium-the-automation-testing-tool/), the undeniable significance of real devices is non-negotiable. The pool of devices deployed for testing should encompass both the latest models such as the iPhone 14 and Google Pixel 7, and the older, still widely-used legacy devices and browsers. This is crucial because in our highly fragmented tech landscape, the specific devices and browsers used to access a website or application can be diverse and unpredictable. The broader the array of devices incorporated into your testing process, the more robust and inclusive the test results.
Confronted with the challenge of maintaining an extensive in-house device lab, the question invariably arises: should one build or buy a device lab? The demands of this conundrum become particularly acute when considering the need for an infrastructure that regularly updates with new and legacy devices and maintains the highest levels of functionality, cost-effectively.
Cloud-based testing infrastructure, such as pCloudy, is an effective solution to this quandary. pCloudy provides a comprehensive suite of 5000+ real browsers and devices that can be accessed for testing from any location worldwide, at any given time.
Reaping the Benefits of Real Device Cloud Testing with pCloudy
Embracing the pCloudy platform is a straightforward process. Users can sign up for free, select a specific device-browser-OS combination, and initiate testing immediately. This offers the ability to simulate user conditions, including factors such as network speed, battery status, geolocation changes (both local and global), viewport sizes, and screen resolutions.
By executing tests on the real device cloud, QA managers can take real user conditions into account, thereby ensuring a high degree of accuracy in test results. As Test Monitoring and Control are instrumental in sculpting a highly functional test cycle, the use of a real device cloud provides QA managers and testers a more authentic and precise set of data. This allows for better management and control in every project, thereby ensuring its success and affirming the pivotal role of real devices in Test Monitoring and Test Control.
Remember, no emulator or simulator can fully replicate the diverse and often unpredictable conditions of real user environments. Hence, real devices hold the key to a more effective and accurate testing process, and cloud-based platforms like pCloudy are leading the way in making this an accessible reality.
Conclusion
To sum up, test monitoring and control are critical for maintaining the quality of your testing process and aligning it with your project goals. By keeping an eye on key metrics and making necessary adjustments, your team can better meet project timelines, enhance the quality of the delivered software, and ensure satisfaction for all stakeholders.
Whether you’re a testing professional looking to sharpen your skills or a project manager seeking to improve your team’s performance, understanding and employing these concepts can significantly elevate your software testing outcomes.
In the ever-evolving software industry, the need for effective test monitoring and control is undeniable. So, consider this guide as your stepping stone towards more efficient, streamlined, and successful software testing endeavors.
The possibilities are endless when you’re in control of your testing process. Remember, it’s not just about preventing defects or maintaining schedules, but also about driving forward towards your goals, with your team, and delivering high-quality software to your end-users. And that is where test monitoring and control shine the brightest. | pcloudy_ssts |

If it's the [Voxxed Days Trieste](https://voxxeddays.com/trieste/), certainly not, but it's definitely time for a post now!
Having an **international event** for devs in _Trieste (Italy)_ is not everyday stuff, and I am really proud to have been a part of it!
Although historically Voxxed has always been associated with Java and the backend, this year there was also a frontend track (React) with a very high level of talks:
1. **Maya Shavin** (Microsoft) opened the FE track with her talk “[Are we React-ing wrongly](https://voxxeddays.com/trieste/schedule/talk/?id=3609)” explaining how to use React for REAL. A talk that I wanted so much because of its wisdom and also because Maya is an explosive mix of sweetness and expertise.
2. **Katarzyna Dusza** (Spotify) brought a talk called “[Modern & secure adaptive streaming on the Web](https://voxxeddays.com/trieste/schedule/talk/?id=4303)”. Her really accurate, clear and in depth presentation will surely simplify the study of these technologies for those who want to use them! As we all know, docs are never that comprehensive and one often has to study from different sources to understand how things really work; Katarzyna did that for us and even added some live coding, so there is no excuse not to give it a try!
3. **Omar Diop** (Learnn) brought “[A 4-Year Retrospective : Lessons Learned from Building a Video Player from Scratch with ReactNative](https://voxxeddays.com/trieste/schedule/talk/?id=3613)”. Unfortunately, I wasn't able to attend his talk because I was busy with “staff stuff”, but I got to talk to him during the speakers' dinner the day before, and he is a bubbly, energetic guy! We got to talk about our side projects (which I LOVE doing) and his are all really interesting!
4. **Edoardo Dusi** (SparkFabrik) with the talk “[ServerComponents are React's superweapon in the Stack Wars: Can PHP strike back?](https://voxxeddays.com/trieste/schedule/talk/?id=5501)” brought one of the trendiest topics of 2024, telling it like only he can. It was a “historical” talk, from the first version of php to NextJs, through the various FE frameworks we have loved and hated... So many good old memories!!!
5. **Borut Jogan** (Honeywell): “[Fail your tasks successfully](https://voxxeddays.com/trieste/schedule/talk/?id=2505)”, a talk that every conference (of any kind) should give space to. He brought attention to the issues of mental health and how to get out of bad situations that any of us might face at work. A talk of a simplicity but disarming power. Really a good time of sharing.
The main track talks were also interesting, but my favorite was the “[Cracking the Code: Decoding Anti-Bot Systems!](https://voxxeddays.com/trieste/schedule/talk/?id=3268)” by **Fabien Vauchelles** (Scrapoxy) who explained how you can do scraping without getting caught. I love these kinds of talks because they encapsulate the REAL experience of several years in one talk of a few minutes 😍
Let me add just a couple of words about the location: how cool is it to do a conference in one (actually two) **cinema**?!? WOW.
And last but not least, I can't thank **Alessandra Laderchi** enough for getting me involved in the program committee and asking me to be part of the staff.
I got the change to work with a great team and meet fantastic people: **Borut Jogan**, **Enrico Giacomazzi**, **Federico Morsut**, **Gabriele Savio**, **Mariela Nasi**, **Ornela Kita**, **Mario Fusco** and **Daniele Zonca**.

1,889,567 | the detailed process for sloving leetcode problem 13 | Frist let us see the problem To solve the question we need find the rule to calculate the sum of... | 0 | 2024-06-15T13:52:57 | https://dev.to/hallowaw/the-detailed-process-for-sloving-leetcode-problem-13-3b6k | beginners, programming, tutorial, cpp | **Frist let us see the problem**
To solve the question we need find the rule to calculate the sum of those roman numbers.
Let us use the LVIII as our first example,we can see that all the roman number left is not smaller than its right,so that we can add the referring integer from right to left,it is 1+1+1+5+50=58,
And there is another situation,let us use MCMXCIV as our second example,we can find I is behind V,so we should use V subtract I to 5-1=4,and next C is bigger than I so we add C 5-1+100=104,but X is smaller than C so we subtract X 5-1+100-10=94,then 94+1000-100+1000=1994,**now,we have knew how to calculate the sum of one roman number,start from right and if the left is smaller than right then use right to subtract left else add the left.**
But before this we need to do sth. to let each roman equal a integer to achieve it it is recommend to transfer the form of string to vector that including the integer by the sequence for each roman number so that we are easy to calculate the sum and compare which is bigger for two roman numbers.
so we have the code as following to transfer to integer vector:
```
for(char ch :s){
switch(ch){
case 'I':
newvec.push_back(1);
break;
case 'V':
newvec.push_back(5);
break;
case 'X':
newvec.push_back(10);
break;
case 'L':
newvec.push_back(50);
break;
case 'C':
newvec.push_back(100);
break;
case 'D':
newvec.push_back(500);
break;
case 'M':
newvec.push_back(1000);
break;
}
}
```
Then we add the calculating model as following:
```
int size=newvec.size();
int sum=newvec[size-1];
for(int i=2;i<=size;i++){
if (newvec[size-i]<newvec[size-i+1])
{
sum=sum-newvec[size-i];
}
else{
sum=sum+newvec[size-i];
}
}
return sum;
```
so the full codes is :
```
class Solution {
public:
int romanToInt(string s) {
vector<int>vec;
vector<int>newvec;
for(char ch :s){
switch(ch){
case 'I':
newvec.push_back(1);
break;
case 'V':
newvec.push_back(5);
break;
case 'X':
newvec.push_back(10);
break;
case 'L':
newvec.push_back(50);
break;
case 'C':
newvec.push_back(100);
break;
case 'D':
newvec.push_back(500);
break;
case 'M':
newvec.push_back(1000);
break;
}
}
int size=newvec.size();
int sum=newvec[size-1];
for(int i=2;i<=size;i++){
if (newvec[size-i]<newvec[size-i+1])
{
sum=sum-newvec[size-i];
}
else{
sum=sum+newvec[size-i];
}
}
return sum;
}
};
```

1,885,015 | Sharing Data Between Components In React | Introduction Effective data management practices are fundamental in building... | 0 | 2024-06-15T13:43:10 | https://dev.to/kenbaz/sharing-data-between-components-in-react-9hn | beginners, react, learning, frontend | #Introduction
Effective data management practices are fundamental in building powerful and efficient React applications. Properly handling and sharing data among components is essential, as it guarantees consistency, reusability, scalability, and performance. This not only ensures that your code is clean and maintainable but also enhances the user experience by keeping the UI synchronized with the underlying state.
> ###Prerequisite
* Basic understanding of JavaScript
* Basic knowledge of React,
Sharing data between components in React is essential for building dynamic and interactive React applications. React offers various methods to carry out this data sharing, each fitting different scenarios and levels of complexity. Understanding these methods is key to effectively managing state, and ensuring smooth data flow within your application.
> This article will be divided into three sections. In the first section, we will discuss **components** and how they serve as building blocks in React applications; In the second section, we will be discussing **props** and how data flows from parent components to child components; And finally, in the third section, we will be discussing **state**, looking at a concept called **Lifting state**. Let's get right into it.
###Section 1
####Understanding React Component Hierarchy
* **Components as building blocks**
Components are isolated pieces of the user interface (UI) which are used for building React applications. A react component is a JavaScript function that includes a combined structure of HTML(markup language), CSS(style), and interactivity or behavior(JavaScript), all working together to create parts of the UI that enable developers like you and me to build detailed or very complicated interfaces, by putting together or assembling simpler, independent components.
> A component can be something as small as a button or something as large as a whole page of an application.
Now that we have an idea of what components are and how they serve as building blocks to our React applications, let's talk about how web pages are displayed by rendering a component tree.
* **Component tree**
A component tree is a hierarchical structure that depicts the arrangement and connections of components in a React application. it visually displays how components are nested within one another, showing the relationship between parent and child components; Take a look at the structure below.
```python
App
|---Header
|---Sidebar
|---MainContent
| |---Content
| | |---ContentBody
| | |---ContentFooter
| |---Content
| | |---ContentBody
| | |---ContentFooter
|
|---Footer
```
In the illustration above:
* **App** is the root component, which is the primary application component.
* **Header**, **Sidebar**, **MainContent** and **Footer** are all child components of App.
* **MainContent** contains two child components, which are **Content**, and **Content** in turn contain further nested child components **ContentBody** and **ContentFooter**.
> Any component housing another component is the parent component, while child components are those components being housed inside the parent component, and these child components can in turn have their own child components.
This hierarchical structure aids the interactivity between parent and child components, showing how data and props flow from parent components to child components, and providing a clear understanding of how various parts of the UI interact.
###Section 2
####Passing data via props
* **Introduction to props**
**props** (short for properties) are inputs used by React components to communicate with one another. A parent component can share information with its child component by providing them with props; this data exchange between parent and child helps make components dynamic and reusable. Props resemble HTML attributes but can carry any JavaScript value, including objects, arrays, and functions.
**Code example**
```javascript
//Parent component
function App() {
return (
<Greeting name="setemi"/>
<Greeting name="Bassey"/>
);
};
//Child component
function Greeting(props) {
return (<h1>Hello, {props.name}<h1>);
}:
```
> In the code example above, the App component sends the name props to the Greeting component, enabling the Greeting component to render a personalized greeting. The Greeting component accepts the named prop and uses it to render the message.
* **Accessing props**
props is an object that can hold multiple named properties, each property is called a named prop and these named props can be accessed in two ways; Either through the dot notation e.g. (props.name) or by destructuring e.g. ({name}).
We have already seen how props can be accessed with dot notation in the code example above, so now we will shift our focus to accessing props by destructuring.
#####Destructuring props
Destructuring props is generally seen as a more concise and readable way to access props, particularly when accessing multiple props within a component. it also clarifies which props the component is intended to use.
**Code example**
```javascript
//Parent component
function MyApp() {
return (<Person name="Bassey" age={27}/>);
};
//Child component
function Person({name, age}) {
return (
<div>
<p>Name: {name}</p>
<p>Age: {age}</p>
</div>
);
};
```
> As you can see in the code example above, destructuring props allows for clear and explicit data sharing between components which improves code readability and maintainability by clearly showing what data is being passed to the child component.
As we've seen in this section, props allow for dynamic interaction between components but often, you are going to want the user to be able to interact with your component, and to achieve this, you need to use **state**, which allows React components to create dynamic and interactive user experiences.
###Section 3
####State in React
In React, state is a key concept for handling dynamic data within a component. It allows a component to store and manage data that can change over time, which is essential for developing interactive and responsive interfaces.
> State is initialized in a component by using the useState hook.
####Importance of state in managing data
* **Dynamic UI Updates**
State allows components to dynamically change their appearance and behavior based on user interactions or other events. For instance, a counter component can utilize state to keep track of the current count and update the display each time the user increments or decrements the counter.
* **Encapsulation and Modularity**
State contains data specific to a particular component, making components more modular and easier to manage. This means that each component can manage its own state independently without affecting other component's state.
* **State-driven Logic**
Components can determine their behavior based on their state. For instance, a component might render different UI elements depending on whether a user is logged in or out, or Show loading skeletons or messages while waiting for data to be fetched.
**Code example**
```javascript
App.jsx
import {useState} from "react";
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<p> Count: {count}</p>
<button onClick="{() => setCount(count + 1)}">Increment<button>
</div>
);
};
```
> In the code example above, state is initialized at the top level of the component by importing the **useState** hook from react. A counter component is defined with a count and setCount state, the count state is initialized to zero(0) while the setCount state is a function used to update the count state.
> The count and setCount state are then passed to the UI elements as props. The `<p>` tag holds the count state which is zero(0), while the `<button>` tag when clicked, calls the setCount function effectively updating the count state (When the button is clicked the count increments from zero(0) to one(1) and so on).
> When naming states, the proper naming convention always goes like this, something, setSomething e.g.(count, setCount).
Another important concept in the relationship between state and components is that each component has its independent state. This means that when you give a component a state and then call that component multiple times in its parent, each component called is going to have its own independent state, which means that any change in one state of a component will not affect the other components irrespective of it being the same component.
```javascript
function ParentComponent() {
return (
<Counter/>
<Counter/>
);
};
```
> Here, each Counter component nested in the ParentComponent has its own independent state, even with it being the same component. Because the Counter component is called twice in its parent, it will appear twice on the component tree, and each instance of it will get its own state.
However, often you will need components to share state and always update together, to achieve this you will need to move state from the individual child component or in this case the Counter component up to the parent component containing them. The concept of moving state from the child component up to the parent component is called **Lifting state**. Let's jump into it.
#####Lifting state
```javascript
function MyApp() {
const [count, setCount] = useState(0)
function increment() {
setCount(count + 1);
}
return (
<div>
<Counter count={count} onClick={increment}/>
<Counter count={count} onClick={increment}/>
</div>
);
};
function Counter({count, onClick}) {
return (
<div>
<p>Count: {count}</p>
<button onClick={onClick}>Increment</button>
</div>
);
}
```
> In the code example above, state has been moved from the Counter component up to the parent MyApp component which then passes the state back to the Counter component as props. Now both the counter components nested inside MyApp component share the same state and as such will update together.
###Summary
This brings us to the end of this article which is about sharing data between components in React. In this article, we started by stating that effective data management practices are essential to building powerful React applications, and during this article, we've discussed some major concepts that aid us manage data effectively in React.
Here is a quick read about the concepts discussed:
* **Components**
We stated that components are isolated pieces of the UI that are used for building React applications.
* **Component tree**
We described a component tree as a hierarchical structure that depicts the arrangement and connections of components in a React application.
* **props**
We stated that props are inputs used by React components to communicate with each other, citing that parent components share information with their child components by providing them with props.
* **State**
Finally, in this article, we stated that providing a component with state allows for dynamic communication between the component and the user.
Before we end the article, let's talk about choosing the right approach to manage your data, as choosing the appropriate approach for managing your data between React components is crucial for building a well-organized, maintainable, and efficient application. Choosing the best approach depends on the specific requirements and complexity of your application.
* **Key things to consider when choosing an approach:**
* **Application complexity**
When building simple applications, you might only require local state and props, while complex or large applications might require the use of context API or state management libraries.
* **Scalability**
Choose an approach that can evolve with your application's needs. Always have the future growth of your application in mind.
* **Performance**
Make sure the selected approach does not cause unnecessary re-rendering and performance issues.
* **Maintainability**
Choose an approach that keeps your code clean and easy to understand.

Handling async... | 0 | 2024-06-15T13:33:36 | https://dev.to/vishalgaurav/an-interesting-promise-use-case-handling-user-interactions-1f1g | What are the use cases that come to our mind when we hear of promises?
1. Handling async operations.
1. Handling some task that will finish in future.
1. Doing something like network or DB calls.
But that's not all to it, we can use it to handle user interactions as well. Let us see how.
## Motivation
So, I was building simple confirmation modal for my React project. It needed to be as simple as possible. A modal with some confirmation text in it and two buttons for accepting or declining. Something like this
## The simple/straight-forward approach
1. Make modal component.
1. Mount it conditionally using state.
1. Handle delete operation inside Modal component.
The code for it looks something like
```js
import { useState } from "react";
const Modal = ({ setShowModal, handleDelete }) => {
return (
<dialog open>
<p>Are you sure you want to delete?</p>
<button
onClick={() => {
setShowModal(false);
handleDelete();
}}
>
Yes
</button>
<button
onClick={() => {
setShowModal(false);
}}
>
No
</button>
</dialog>
);
};
function App() {
const [showModal, setShowModal] = useState(false);
const handleDelete = () => {
//perform delete operation here...
console.log("hey");
};
return (
<div>
{showModal && (
<Modal setShowModal={setShowModal} handleDelete={handleDelete} />
)}
<button onClick={() => setShowModal(true)}>Delete</button>
</div>
);
}
export default App;
```
## Did you notice the problem?
The above code works all fine, however there are few issues
1. We need to maintain a state for showing/hiding modal and pass the setter function to modal.
1. We need to pass the business logic to the modal(delete handler).
1. The flow of code is not linear anymore, the deletion is being handled by some other component away from the main component(App)
1. Not clean code.
## The idea of asynchronicity
It was this moment when I felt there must be a better way to handle this. I noticed that a click operation by user is also an async operation! It can happen anytime in future. This is where the idea of Promise kicked in.
## The better way
1. We can make some custom hook from where a promise is returned which can be awaited upon.
1. The promise can resolve to either true or false which can show if the user accepts or rejects.
1. The custom hook can also return a Modal component which can be directly use in at the place of application.
1. We can also make custom hook configurable to accept different messages.
## A Custom hook
```js
import { useState } from "react";
const useConfirmation = () => {
const [modalState, setModalState] = useState({
showModal: false,
resolve: null,
message: "",
});
const Modal = () => {
return (
<dialog open={modalState.showModal}>
<div>
{modalState.message}
<button
onClick={() => {
setModalState((prev) => ({
...prev,
showModal: false,
}));
modalState.resolve(false);
}}
>
Close
</button>
<button
onClick={() => {
setModalState((prev) => ({
...prev,
showModal: false,
}));
modalState.resolve(true);
}}
>
Confirm
</button>
</div>
</dialog>
);
};
const confirm = (message) => {
return new Promise((resolve) => {
setModalState((prev) => ({
resolve: resolve,
showModal: true,
message: message,
}));
});
};
return { Modal, confirm };
};
export { useConfirmation };
```
The Modal component has it's own state which stores the message, resolve function returned by promise and show state.
## Application
```js
import { useConfirmation } from "./useConfirmation.jsx";
function App() {
const { Modal, confirm } = useConfirmation();
const handleDelete = async () => {
const isItOkToDelete = await confirm("Are you sure you want to delete?");
console.log(isItOkToDelete);
};
return (
<div>
{Modal()}
<button onClick={handleDelete}>Delete</button>
</div>
);
}
export default App;
```
The `useConfirmation` hook returns a function which returns a promise. The function also takes in a message argument to display inside modal. We can await this promise to either receive true/false and proceed with the code flow ahead.

1,889,563 | What is low Latency? | Latency in networking is the time it takes for a packet of data to travel from its source to... | 0 | 2024-06-15T13:25:54 | https://www.metered.ca/blog/what-is-low-latency/ | webdev, javascript, devops, webrtc | Latency in networking is the time it takes for a packet of data to travel from its source to destination.
This time is typically measured in milliseconds as the data travels at the speed of light, but variety of factors influence the time required to travel
These factors include the
1. The phycical distance between devices
2. the quality of network connection, this include factors like jitter, the connection is fiber ir over wifi etc. If the quality of the netwok is better then the latency is lower
3. the number of routers, swithces that are between the devices. If there are more devices then there is greater latency
4. the traffic congestion is another factor, there is there is a lot of congestion then there is more latency
## **Latency Vs Bandwidth**
Latency is a the time delay in sending a packet of data from one point to another
bandwidth is the maximum rate at which data can be transferred from one point to another in a network over a specific period of time. Bandwidth is measured in bits per seconds
Think of it as a pipe transferring data from one point to another, bigger the bandwidth means bigger the diameter of the pipe, hence more data can travel.
Latency on the other hand is the time delay in a packet of data reaching its destination. think of it like, how long is the pipe and hence how long the data needs to travel, are there any leaks in the pipe, are the valve and regulators in the pipe and how many are there
Even a pipe with a large diameter (high bandwidth) there can be delays in a data reaching its destination because of distance, congestion, leaks, valves and regulators ( High Latency) and such that.
## **Why Low Latency is Important for performance**
Low latency is important for performance in many applications, this is most important in applications that require real time communications like notifications and real time chat etc
1. **Real Time Applications:** Real time apps such as real time chat, online gaming and gaming platforms like strada survive only thorough low latency, ultra low latency live streaming for sports etc require req and response feedback cycle which is only achievable with low latency
2. **Enhanced Responsiveness:** Low latency results in highly responsive applications, the apps even through run through the internet but it feels as if they are running natively thanks to low latency networks
3. **Efficiency in Automated Systems:** If you have automated systems like for example automatic trading bots that trade based on signals in the market, these systems need ultra low latency because markets are moving and these systems need to make decisions in real time.
## **Impact of Latency on User Experience and Operational Efficiency**
1. **User Experience (UX):** High latency can badly impact user experience, expecially in instances where the nature of the app is real time. For example if someone is
2. **Operational efficiency:** In business latency can affect the efficiency of the operational processes that depend on timely data
3. **Quality of service:** Quality of service degrades due to latency issues, this is important in software business that provide api and sdk services to other business and hence the quality of service of software businesses is dependent of low latency
## **How can you measure Latency?**
### **Ping**
The most common tool for measuring latency is `ping` command. This command line utility sends a ICMP echo request to the target host and listens for replies
The time taken for these packets to travel to the host and back is called as round-trip time, this helps in assessing network stability and consistency in latency.
### **Traceroute**
The tranceroute is a utility that tracks a path that a packet of data travels through form the source device to the destinations
In the path the packet encounters many devices such as routers and switches, it provides the list of routers and the time to reach that devices when it passes it
This tools can be used to diagnose where latency is occouring in the path of the packet from the device to the destination.
## **What are the causes of latency?**
Here are some of the majot causes of latency:
### **Propagation Delay:**
This is a primary factor and this refers to the time it takes for the packet of data to travel from one place to another through a medium of travel such as fiber or wifi.
The fastest the packet travels is close to the speed to light, but phycical distance and the type of medium such as wifi is slower than fiber are significant factors
### **Transmission Medium:**
The type of medium through which the data is travels also plays a factor in determining the speed of travel and hence the latency
the fastest medium is the fiber optic cable, other mediums are slower and include copper wire, wifi radios etc.
### **Router and Switch Processing Time**
Routers and switches that are in the path of the data also plays a role, any additional router or switch in the path increases latency that is due to additional processing and directing the data to the next hop. The more hops are there between the source device and the destination device the higher the latency
### **Traffic Load**
High traffic load leads to more latency and the medium of travel gets crowded and then packets of data gets queued to be processesed and transmittedf
congestion leads to traffic bottlenecks much like congestion in traffic on highways leads to traffic bottlenecks
### **Network Protocols**
Different Protocols require different amount of processing time. What type of network protocol you are using to transmit the data also affects the latency
### **Server Processing Time**
How fast the server processes the request and responds to the request also affects the latency of the data
### **Quality of Service (QoS) settings**
If there are some quality of service settings done on the router than this could also affect the latency. As some services will have priority in processing and other have a lower priority. the service with a lower priority might experience greater latency as the data packets might have to wait in a queue to be processed and then transmitted
## [**Metered TURN servers**](https://www.metered.ca/stun-turn)
1. **API:** TURN server management with powerful API. You can do things like Add/ Remove credentials via the API, Retrieve Per User / Credentials and User metrics via the API, Enable/ Disable credentials via the API, Retrive Usage data by date via the API.
2. **Global Geo-Location targeting:** Automatically directs traffic to the nearest servers, for lowest possible latency and highest quality performance. less than 50 ms latency anywhere around the world

15. Supports both TCP and UDP
16. Free Unlimited STUN
## **How can you improve network latency issues?**
### **Upgrade Network Infrastructure:**
Always use high quality networking hardware, like optical fiber and good quality routers etc can help reduce latency issues
### **Minimize physical distance**
Always try to minimize the physical distance between devices, you can connect to devices that are closer to each other without much latency
### **Optimize network design and configuration**
Network design also plays an important role in latency. Designing a good network where data does not have to travel between hops to reach other devices helps in reducing latency
### **Utilize modern Network Protocols**
Use modern networking protocols like UDP and accelerated TCP protocols for faster transmission of data.
### **Reduce Network load**
Reduce unnecessary data transfer so as to reduce the load on the network. having a lot of traffic in the network creates network congestion which in turn increases latency
### **Regularly Monitor and optimize Network**
Always keep a check and regularly monitor network activity to see if there are any problems with the network which can be improved and the speed restored
### **Improve software efficiency**
Write better software on the server and also on the client that sends data as needed which imporves latency and reduces load times
Thus we have learned in this article what is low latency, and how we can improve latency for better response time and better experience in content consumtion as well as in business. | alakkadshaw |
1,889,558 | 5 Ways DevOps Services Can Boost Your Business Agility | In today's fast-paced business world, agility is king. The ability to adapt quickly to changing... | 0 | 2024-06-15T13:17:56 | https://dev.to/marufhossain/5-ways-devops-services-can-boost-your-business-agility-2o8o | In today's fast-paced business world, agility is king. The ability to adapt quickly to changing market demands and customer needs is crucial for success. Traditional development methods often struggle with this, creating bottlenecks that slow down innovation. DevOps services offer a powerful solution, breaking down barriers and streamlining processes to dramatically enhance your business agility.
**The Struggles of Traditional Development**
Traditional development methodologies often suffer from silos between development and operations teams. Developers write code, and operations take over to deploy it. This lack of communication can lead to issues like:
* **Slow Feedback Loops:** Bugs and errors take longer to identify and fix, delaying releases.
* **Inconsistent Deployments:** Manual processes increase the risk of errors and inconsistencies during deployment.
* **Limited Innovation:** The slow pace of development hinders the ability to test new ideas and features quickly.
These limitations make it difficult for businesses to react quickly to market changes or customer feedback.
**How DevOps Services Unleash Agility**
DevOps services bridge the gap between development and operations, fostering a culture of collaboration and shared ownership. This translates into several key benefits that boost your business agility:
* **Streamlined Development & Operations:** DevOps breaks down silos, allowing developers and operations to work together throughout the development lifecycle. This fosters faster issue resolution and smoother deployments.
Imagine a development team and operations team working side-by-side. Developers write code, and operations engineers are involved from the start, understanding the code and anticipating deployment needs. This constant communication allows for quicker fixes and smoother rollouts.
* **Continuous Integration & Delivery (CI/CD) Pipelines:** CI/CD pipelines automate the software development process, including building, testing, and deploying code. This allows for faster feedback loops and quicker releases of new features.
Think of a CI/CD pipeline as an automated assembly line. Code gets built, tested, and deployed automatically, with each stage feeding into the next. This continuous flow eliminates manual steps and speeds up the entire process.
* **Infrastructure as Code (IaC):** IaC allows you to define and manage your infrastructure (servers, networks, etc.) as code. This enables automated provisioning and configuration, leading to faster deployments, improved consistency, and reduced risk of errors.
Imagine managing your infrastructure with scripts instead of manually configuring each server. IaC lets you define your infrastructure needs as code, allowing for quick and reliable deployments across different environments.
* **Automation & Continuous Monitoring:** DevOps services leverage automation tools to streamline repetitive tasks like deployments and configuration management. Additionally, continuous monitoring helps identify and resolve issues proactively, leading to improved application performance and stability.
Repetitive tasks get automated, freeing up your team to focus on innovation. Continuous monitoring acts like a watchful eye, identifying problems before they impact your users.
* **Enhanced Security:** DevSecOps practices integrate security considerations throughout the entire development lifecycle. This proactive approach helps build secure applications from the start, reducing vulnerabilities and improving overall application health.
Security doesn't become an afterthought with DevOps. Security best practices are woven into the development process, ensuring your applications are built with security in mind from the very beginning.
**Real-World Examples of Agility**
Company A, a leading online retailer, used D[evOps outsourcing](https://www.clickittech.com/devops-outsourcing/?utm_source=backlinks&utm_medium=referral
) to implement a CI/CD pipeline. This resulted in a 75% reduction in deployment time, allowing them to release new features and bug fixes much faster. This agility helped them stay ahead of the competition and delight their customers.
**Conclusion**
By adopting DevOps services, you can break down silos, automate processes, and foster a culture of collaboration. These factors work together to dramatically boost your business agility. With faster feedback loops, quicker deployments, and a focus on continuous improvement, you'll be well-positioned to adapt to change, innovate quickly, and stay ahead of the curve. If you're looking to unlock the full potential of your business, consider exploring how DevOps services can help you achieve greater agility.

1,889,557 | Which programming language should you choose | Each programming language has its own purpose, they all are a tool to solve a specific problem, and... | 0 | 2024-06-15T13:15:35 | https://henriqueleite42.hashnode.dev/what-programming-language-should-you-choose | beginners, programming, career, development | Each programming language has its own purpose, they all are a tool to solve a specific problem, and you should choose the one that really fits your needs.
## The languages
### JavaScript
```javascript
console.log("Hello World!")
```
JavaScript is a terrible and confusing language (see more [here](https://javascriptquiz.com)), but unfortunately it's the only option that we have for working with Frontend Web development. You should choose (or is forced to) use it when your goal is to create interactive Frontend Websites.
In any other case, JavaScript MUST be avoided, it's unsafe, underperforming, makes no sense, requires lots of configurations and libraries to do the basics, and it's infested with terrible practices.
"Choose" it if you want to become a Frontend Web developer.
### PHP
```php
<?php echo 'Hello, World!'; ?>
```
PHP still the most used language for the Web, mostly because most of the websites are legacy or build with WordPress, an easy-to-use tool where you can start almost with no knowledge about programming.
You will find a lot of jobs to work with PHP, but it's "for the old people", and the new generation is avoiding it because of the [memes](https://www.google.com/search?sca_esv=c25313c4b5559b8f&sxsrf=ADLYWIKE23m8_uZWq4oYjGXpLRKJ_VydBA:1718454482517&q=php+memes&udm=2&fbs=AEQNm0DYVld7NGDZ8Pi819Yg8r6em07j6rW9d2jUMtr8MB7htoxbI0iAKNRPykigVf3e9aputkbr8jzmN5LYbANOqrq5HYnx4MjtyMxZ94LvgeHWmGBcuWUoydKfNaoB5JMdZlMtXmg2De2y5O7nn-eTbNdYHsRiT1RQ-pB6qp3ejXJ5VpdCk5NA1Jug5hVR16L7F-A1C1p-4xpfp7qj2HsGNaipPZQOiw&sa=X&ved=2ahUKEwjIz_jnzd2GAxXoqZUCHWIUCvQQtKgLegQIERAB&biw=1882&bih=977&dpr=1), and yeah, they are kinda right, but PHP was very important for the early Backend development.
Choose it if you want to (or have to) work on legacy systems, or systems that are for companies which the focus isn't on their tech, like Stores or Supermarkets.
### Python
```python
print "Hello World"
```
Python is a very simple language, ideal for beginners that want to start in the programming world or for non-programmers that need to automate a task.
It's heavily used for Machine Learning, Neural Networks and similar, usually build by mathematicians.
Pythons has terrible performance, so it should be used in environments where you don't need things to be fast, like training your AI, running things locally to automatically format your CSVs, move your mouse so your companies spyware thinks you are working and similar.
Python should not be used in production, but the result of what is produced by python can.
Choose it if you want to start in programming but find it too hard in any other way, or if you aren't a programmer and don't want to be one, but needs to automate something or create AIs to take someone's job.
### Java
```java
class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World!");
}
}
```
Java is the good-old trustable language, used for most backend systems that must be reliable, like banking. It's kinda verbose and heavy, but a good language overall, has lots of job positions, good practices, great developers. It's the one that you can't go wrong.
Choose it if you want something guaranteed, even if you don't work directly with Java, the things that you learned for sure will be useful in your career.
### Golang
```go
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
```
Go is a safe, fast and easy programming language, it's growing, but not a lot of companies out there have job positions to work with this.
### C++
```cpp
#include <iostream>
int main() {
std::cout << "Hello World!";
return 0;
}
```
C++ is the language for who wants to develop games. You will probably use Unreal Engine or (very, very rarely) develop your own. Most (maybe all) big games are developed using this language.
### Lua
```go
print("Hello World")
```
Lua is also for gaming, its focus is not to be performative, but to be very easy to learn and modify. If you want to create a game that supports a lot of mods and has a great community, use Lua. Your community will love to make mods and expand your game, it will also help with its growth.
### C, Rust and Zig
```c
#include<stdio.h>
int main(void) {
printf("Hello World\n");
return 0;
}
```
```rust
fn main() {
println!("Hello World!");
}
```
```plaintext
const std = @import("std");
pub fn main() !void {
std.debug.print("Hello, World!\n", .{});
}
```
Low level languages, perfect for things that really needs performance, like Databases (creating databases, not using them!) and Operational Systems.
You will probably not get a job with these languages, but may need to develop something using them if you were hired by a medium/big tech company.
### All other languages
Don't use it, it's not worth it.
### Let's summarize
* JavaScript: Frontend Web
* PHP: Legacy backend
* Python: For non-programmers
* Java: Safe in all means, good option overall
* Golang: Good but not very used
* C++: Very performative gaming, for competitive or immersive games
* Lua: For community driven games
* C, Rust and Zig: For OSs and Databases.
## For the fanboys
This is a meme that represents "You can cry as much as you want, but it will not change a thing".
## Conclusion
Hope that it helps mainly the beginners to understand the purpose of each language and avoid people that only want their money, selling courses about "LEARN THIS LANGUAGE AND YOU WILL MAKE 500K A YEAR!!!", please, don't fall for these schemes.
If you have different options (and don't want to cry about how your language is the best language in the world and should be used everywhere, except for C, C is the best), please leave it in the comments and let's talk about it! | henriqueleite42 |

I will provide practical tips and guidance to help beginners navigate through the vast amount of information available and identify the essential resources and learning paths to kick-start their AWS cloud engineering journeys.
As a Cloud Computing Enthusiast with a few months hands on experience on AWS, I've certainly encountered the challenge of information overload when it comes to cloud engineering. It's a common hurdle that many beginners like I face when first diving into the expansive world of cloud computing. The concept of information overload in the context of cloud engineering refers to the sheer volume and complexity of data, services, and technologies that users must navigate. The AWS cloud platform alone offers hundreds of services spanning compute, storage, networking, databases, analytics, and more.
Add to that the myriad of architectural patterns, security best practices, pricing models, and operational considerations - and it can quickly become overwhelming for those new to the field.
This information overload can manifest in several ways:
- Difficulty identifying the most relevant AWS services and features for a given use case.
- Struggling to understand how various AWS components integrate and interact.
- Feeling paralyzed by the breadth of configuration options and deployment choices.
- Becoming bogged down in technical jargon and cloud-specific terminology.
**Understanding Your Goals**
Having a structured approach to learning is crucial for avoiding information overload and overwhelms when it comes to AWS security and cloud engineering in general. The cloud landscape is vast, complex, and ever-evolving, making it essential to have a well-defined strategy for continuous learning and skill development.
In my opinion, here are some key reasons why a structured approach is essential:
- Prioritization: With the abundance of resources, services, and best practices available, it becomes crucial to prioritize your learning objectives based on your organization's security requirements, compliance mandates, and risk profile. A structured plan helps you focus on the most relevant and impactful areas first, avoiding the trap of trying to learn everything at once.
- Efficient Resource Utilization: Developing a structured learning plan helps you identify and leverage the most authoritative and up-to-date resources, such as official AWS documentation, training courses, and industry-recognized certifications. This ensures you're investing your time and effort into high-quality, and reliable sources.
- Continuous Improvement: The cloud security landscape is constantly evolving, with new threats, services, and best practices emerging regularly. A structured approach enables you to incorporate continuous learning into your routine, ensuring you stay ahead of the curve and adapt to changes effectively.
- Knowledge Retention: Attempting to learn too much, too quickly, can lead to cognitive overload and poor knowledge retention. A structured approach allows you to pace your learning, reinforce concepts through practical exercises, and solidify your understanding before moving to the next topic.
To implement the structured approach stated above you can;
1. Define your learning goals and priorities based on your career projection.
2. Develop a learning roadmap that breaks down your goals into manageable modules or milestones.
3. Leverage authoritative resources like AWS documentation, official training, and certification paths.
4. Incorporate hands-on labs, projects, and real-world use cases to reinforce your theoretical knowledge.
5. Regularly review and update your learning plan to accommodate new developments and emerging best practices.
6. Foster a culture of knowledge sharing and continuous learning.
By embracing a structured approach to learning, you can navigate the complexity of the AWS platform more effectively, avoid information overload, and develop the skills necessary to build and maintain a robust, secure cloud environment.
**A Well-Defined Vision for the Future**
Without a clear understanding of your goals and desired career trajectory, it's all too easy to get lost in the vast sea of cloud technologies, services, and certifications. The AWS ecosystem alone offers hundreds of potential paths - from cloud architecture to DevOps, from data engineering to security specialization. Trying to tackle them all at once is a recipe for overwhelm and dissatisfaction.
Instead, the most successful cloud engineers start with a well-defined vision for their future. Are you aiming to become a Cloud Solutions Architect, responsible for designing and deploying large-scale, enterprise-grade infrastructures? Or perhaps you're drawn to the automation and DevOps aspects of cloud engineering, hoping to streamline software delivery pipelines?
“**Clarifying your core objectives**” - whether it's attaining a specific job title, developing a particular skillset, or solving a particular business challenge - allows you to laser-focus your learning and development efforts. It helps you identify the most critical AWS services, features, and certifications to prioritize, rather than getting side-tracked by peripheral topics.
Furthermore, aligning your cloud engineering aspirations with your broader career goals is equally important. How does mastering cloud technologies fit into your long-term professional ambitions? Is it a means to an end, like advancing into a leadership role, or is it the end goal itself?
By clearly defining these objectives upfront, you can create a tailored learning plan that maximizes your time and resources. You'll be able to make more informed decisions about which cloud skills to invest in, which certifications to pursue, and which real-world projects to take on.
Equally important, this clarity of purpose will provide a vital source of motivation and resilience as you navigate the inevitable challenges of cloud engineering. When faced with information overload or moments of self-doubt, you can always refer back to your core objectives to stay focused and determined.
So, I strongly encourage any aspiring cloud engineer to take the time to thoughtfully reflect on their career aspirations and how mastering cloud technologies can help achieve those goals. It's a critical first step towards cutting through the noise and becoming a confident, capable cloud practitioner.
**Identifying Essential AWS Resources**
When it comes to navigating the vast complex AWS ecosystem, it's all too easy to get swept up in trying to "learn it all." However, that approach is almost guaranteed to lead to feelings of frustration and being overwhelmed. Instead, the key is to establish a series of incremental, measurable goals that align with your broader career objectives. Rather than trying to become a Jack-of-all-trades from the onset, begin by mastering the core AWS services, concepts, and architectural patterns. This foundational knowledge will serve as a solid launchpad for more specialized skill development.
As discussed earlier, aligning your goals with your desired career path is crucial. If you aspire to be a cloud solutions architect, for example, focus on learning about high-availability design, disaster recovery, and cost optimization. If you're interested in DevOps, prioritize automation, CI/CD, infrastructure as code etc.
Break down your broader objectives into manageable, bite-sized goals. Perhaps your first milestone should be to pass the “AWS Certified Cloud Practitioner Exam”, followed by the Solutions Architect Associate, and then progressing to the Professional level.
Celebrate these incremental achievements along the way and by so doing you create a short-term and long-term milestone for yourself.
Regularly assess your progress against your goals and be willing to adjust your plan if needed. Some goals may prove easier or more difficult than anticipated. Remain flexible and adapt your approach accordingly.
Take advantage of the wealth of high-quality training materials, tutorials, and certification programs available from [AWS](https://aws.amazon.com/certification/?gclid=CjwKCAjwjqWzBhAqEiwAQmtgT1FR1n1TVxsu5gNOQ-KkQwCHzWk5xF5Lzi6VbPQ0cPkNGp_WyAfPwxoCc9UQAvD_BwE&trk=bb34ae6f-5d1d-44c1-bb6e-acd0a6335c78&sc_channel=ps&ef_id=CjwKCAjwjqWzBhAqEiwAQmtgT1FR1n1TVxsu5gNOQ-KkQwCHzWk5xF5Lzi6VbPQ0cPkNGp_WyAfPwxoCc9UQAvD_BwE:G:s&s_kwcid=AL!4422!3!653446744771!e!!g!!aws%20training%20and%20certification!19926464807!148637730718) and other trusted providers. These structured learning paths can help ensure you're efficiently acquiring the right skills at the right pace.
While it's important to have a clear focus, don't neglect the value of cultivating a broad understanding of the AWS ecosystem. Exposure to a diverse range of services, even if not at an expert level, can unlock new perspectives and applications.
AWS is the world's most comprehensive and widely adopted cloud computing platform, offering over 200 fully featured services across computing, storage, databases, networking, analytics, machine learning, IoT, and more.
At the core of the AWS ecosystem are foundational infrastructure services like Amazon EC2 for scalable computing, Amazon S3 for object storage, and Amazon VPC for secure virtual networking. Beyond these core services, AWS provides a vast array of higher-level solutions for databases, analytics, application development, security, and compliance. This allows organizations to build sophisticated, scalable cloud applications and architectures.
The breadth and depth of the AWS platform is a key advantage, as it enables cloud teams to innovate faster and operate more efficiently. However, the sheer complexity of the AWS ecosystem can also be overwhelming, emphasizing the importance of a focused, strategic approach to learning and skill development.
**Highlighting Key AWS Resources**
Starting with the official AWS documentation, this is an invaluable and comprehensive source of information on all of the AWS services, features, and best practices. The [AWS Documentation portal](docs.aws.amazon.com) covers everything from service overviews and user guides to API references and developer resources. In addition to the core documentation, AWS also publishes a wealth of whitepapers and technical content that dive deeper into specific use cases, architectural patterns, and service-level details.
Some particularly useful whitepaper collections include:
- AWS Well-Architected Framework - Guidance on designing and operating reliable, secure, efficient, and cost-effective systems on AWS.
- AWS Security Whitepapers - In-depth information on security services, compliance, and implementing secure architectures.
- AWS Architectural Centre - Reference architectures, design patterns, and implementation guides for common cloud use cases.
When it comes to hands-on training and skills development, AWS offers several reliable resources:
- AWS Training and Certification - Instructor-led courses, digital training, and certification programs to validate cloud expertise.
- AWS Blogs - Technical posts covering new service launches, best practices, and thought leadership.

Additionally, the broader AWS community has created a wealth of third-party content, such as AWS-focused books, tutorials, and video courses that can supplement the official AWS resources.
The key is to leverage this diverse set of documentation, whitepapers, and training materials to build a comprehensive understanding of the AWS platform, stay up-to-date on the latest service updates and features, and validate your cloud engineering skills through recognized certification programs.
**Overcoming Challenges**
One of the primary challenges is the sheer breadth of the AWS service catalogue. With over 200 services spanning computing, storage, databases, networking, analytics, machine learning, and more, it can be overwhelming to know where to start and how to prioritize your learning.
The key here is to adopt a focused, strategic approach. Rather than trying to learn everything at once, it's important to identify the core services and capabilities that are most relevant to your specific goals and job functions. This could mean starting with foundational infrastructure services like EC2, S3, and VPC, then building out your knowledge into the higher-level services that align with your application development, data analytics, or security requirements.
Another common challenge is keeping up with the rapid pace of innovation and service updates within the AWS ecosystem. AWS is continuously launching new services, features, and capabilities, which can make it difficult to maintain a current, up-to-date understanding of the platform.
To address this, it's crucial to develop the habit of regularly reviewing the AWS What's New page, AWS Blog, and AWS Online Tech Talks. This will help you stay abreast of the latest service releases, best practices, and architectural patterns. Additionally, investing in on-going training and certification can ensure your skills remain current and relevant.
Many cloud engineering learners struggle with translating conceptual knowledge into practical, hands-on experience. While the AWS documentation and whitepapers provide excellent theoretical information, actually building and deploying cloud solutions requires dedicated lab time and project-based learning. This is where initiatives like the AWS Certified Solutions Architect - Associate Certification can be particularly valuable. The exam prep process and hands-on practice questions force you to apply your knowledge to real-world cloud engineering scenarios. Additionally, participating in AWS community events, hackathons, and user groups can provide further opportunities for practical, collaborative learning.
Seeking out mentorship can also be invaluable when navigating the AWS learning curve. Connecting with experienced cloud engineers, whether through formal training programs, online communities, or professional networks, can provide guidance, answer questions, and offer real-world perspectives.
Mentors can help you identify the most relevant AWS services and features to focus on, provide feedback on your project work, and share strategies for staying up-to-date with the rapid pace of platform updates.
In terms of maintaining motivation and momentum, it's important to set clear, achievable goals for your cloud engineering skill development. Break down larger objectives, like earning a specific AWS certification, into smaller, measurable milestones that you can consistently work towards.
Celebrating your progress, whether it's mastering a new service, passing a certification exam, or deploying your first production-ready cloud architecture, can help sustain your motivation and enthusiasm.
Additionally, immersing yourself in the broader AWS community can be a great source of inspiration and support. Participate in online forums, attend local user group meet-ups, or even contribute to open-source projects. Engaging with like-minded cloud engineers can reinforce your learning, expose you to new ideas, and keep you energized on your professional development journey.
**Conclusion**
Persisting through challenges with resilience and motivation is key. Set clear, achievable learning goals and milestones to sustain your momentum, and be sure to celebrate your progress and accomplishments along the way to maintain enthusiasm. Embrace obstacles as opportunities to deepen your understanding, rather than roadblocks, and maintain a persistent, resilient attitude.
The overarching message is to approach cloud engineering skill development with a strategic mind-set, maximize the use of quality learning resources, and maintain a persistent, resilient attitude in the face of challenges. By doing so, you'll be well on your way to mastering the AWS ecosystem and unlocking a world of exciting career opportunities.
Additionally, breaking down the cloud ecosystem into manageable chunks, and focusing on foundational services and concepts first, can help cloud engineering beginners navigate the complexity more effectively.

1,830,586 | Exploring ORM - Object Relational Mapping | Databases are an immensely powerful tool for developers, as they allow us to store and access... | 0 | 2024-06-15T12:48:39 | https://dev.to/sashafbrockman/exploring-orm-object-relational-mapping-51lm | Databases are an immensely powerful tool for developers, as they allow us to store and access information across multiple uses of a program. Without them, most of the information that we create ends up becoming inaccessible once the application is run and closed. Amongst the information that would otherwise be lost is data related to class instances. Let's say you have an application that displays information about an account at a bank. One of the ways we can represent this account is by using a class that has variables for information such as the name, balance, account number, etc.
In order to store this data, and eventually retrieve and reassign it to an instance, we will need to implement **Object Relational Mapping**, or **ORM** for short. **ORM** simply refers to the method by which we set up classes to store and retrieve information to some database. For the case of this specific blog post, we will be looking at how to implement **ORM** using **Python** and **SQLite**.
## Setup
First and foremost, we need to do a little bit of setup. We start by installing **sqlite3** into our workspace. Once that is done, we need to import it into our file and initialize our connection to our database file and a cursor on this connection to execute commands like so:
```
import sqlite3
CONN = sqlite3.connect(database.db)
CURSOR = CONN.cursor()
```
## create_table
With that setup done, we can move on to actually creating our mapper. Let’s continue with our earlier example of a Customer class. First, we need to actually create a table to store the data in. We can create a class method that will handle that for us:
```
@classmethod
def create_table(cls):
sql = “””
CREATE IF NOT EXISTS customers (
id INTEGER PRIMARY KEY ,
name TEXT,
account_number INTEGER,
balance REAL
)
”””
CURSOR.execute(sql)
CONN.commit()
```
Running this method on our Customer class will give us a table that we can actually store and retrieve data from.
## delete_table
But before we start doing that, let’s make a method to delete our table in case we want to have a fresh start:
```
@classmethod
def delete_table(cls)
sql = “””
DROP TABLE IF EXISTS customers;
”””
CURSOR.execute(sql)
CONN.commit()
```
Both of these class methods above have three main elements, the **SQLite** code that we want to run, our **CURSOR** to execute that code, and out **CONN** to commit the changes to our database.
## save and delete
Now that we have methods to create and delete our table, let’s create corresponding methods to create and delete table rows for our class attribute. Instead of class methods, these two methods are only meant to be called on an instance of a class, not the class object itself:
```
def save(self):
sql = “””
INSERT INTO customers (
name, account_number, balance
)
VALUES (?, ?, ?)
”””
CURSOR.execute(sql, (
self.name, self.account_number, self.balance
))
CONN.commit()
self.id = CURSOR.lastrowid
type(self).all[self.id] = self
def delete(self):
sql = “””
DELETE FROM customers
WHERE id = ?
“””
CURSOR.execute(sql, (self.id,))
CONN.commit()
del type(self).all[self.id]
self.id = None
```
In our save method, we are introducing a few new steps. First are the question marks in `sql`. These are there to act as place holders for the data we want to pass through. We pass the information through when we call execute as the second parameter. You may have noticed that there is an extra comma in the delete method after `self.id`. This is because the second argument for execute needs to be a **tuple**, so we have to include the comma even if we’re only passing a single variable.
After we add our information to the table, we set the `id` of our instance equal to its corresponding `id` in the table. We use that `id` to save our instance to a dictionary object that is a class attribute. Our attribute, called `all`, is defined as an empty dictionary at the top of our class and is used to keep track of all existing instances of our class. Without it, we could end up wasting a lot of memory by accidentally creating multiple identical instances.
We also use `id` to find the row in our table that we want to delete. After deleting the info from the table, we need to remove the object from our all dictionary and remove the instance’s id.
## instance_from_db and find_by_id
Now that we have our methods to manipulate information within the table, the last of our necessary methods are going to handle the retrieval of data from the table and creation of a new instance. Both of these methods are going to be class methods:
```
@classmethod
def instance_from_db(cls, row):
customer = cls.all.get(row[0])
if customer:
customer.name = row[1]
customer.account_number = row[2]
customer.balance = row[3]
else:
customer = cls(row[1], row[2], row[3])
customer.id = row[0]
cls.all[customer.id] = customer
return customer
@classmethod
def find_by_id(cls, id):
sql = “””
SELECT * FROM customers
WHERE id = ?
”””
row = CURSOR.execute(sql, (id,)).fetchone()
return cls.instance_from_db(row) if row else None
```
Let’s break these last two methods down. Starting with `instance_from_db`, we take our row provided from `find_by_id` and try to find a corresponding instance that already exists in our all dictionary. If one does exist, it takes the information from the table and updates the instance to make sure they match. If it doesn’t exist, it goes ahead and makes and returns a new instance.
Finally, there’s our `find_by_id` method which takes an id as a parameter and returns a customer instance. Most of the code in it should look familiar, but there is one new thing. The `fetchone` method at the end takes the executed code and returns a list containing the information from the first row that meets the `WHERE` condition.
We can write as many methods as there are different ways of interacting with the table using **SQLite**. However, with these methods, you have the bare bones of a basic **ORM**. Good luck and happy coding!

While looking at IDEs I stumbled upon a way to write and run Python directly in the Browser just with a Notepad. So I opened Notepad and wrote a boiler plate html file with a Python Library called pyscript...core.js. There was no IDE or server involved, just my frontend file. All I had to do was double click the HTML file and my Python, Javascript, JSON and HTML played very nicely together.
Also I had recently ditched React in favor of Plain JS and started fetching JSON from S3 versus the traditional SQL approach. So Fetch in Python? Was this possible? Fetch is JS and Python is not, so I thought. But thanks to WebAssembly now we can combine both Python and Javascript on an HTML page.
Since I never really used much Python and I was mostly Plain JS without Node I was accustomed to using CDN Libraries in my HTML. I was drawing some Python line charts one day and got to thinking about hosting them in JS too. Bokeh was the answer. Bokeh is both a Python library and a JS Library so it fit my new configuration. Now my solution was totally serverless.
So lets look at some Pyscript now. It has only been around since 2022. In 31 lines of code I can do all the above. The only drawback is that my chart takes 8 seconds to load and from Python IDLE it takes 3 seconds. But the data is worth waiting for because of the value it adds to our Marketing effort. Recently Pyscript had a complete rewrite. This code used to be 60 lines just 2 months ago and prior to that it was 100+ lines using popular competitor Matplotlib.
So now below is the no brainer code written in pyscript newest release, June 2024
Note: this is a first for this newest way of writing pyscript as of 6-15-24
Beware that versioning is critical with Pyscript and Bokeh and is not backward compatible.
```js

yAxis=[i['Quantity'] for i in data] #grab s3 data using loop
p = figure(width = 700, height = 600) #beware that much code u see still uses plot_width /height which does not work anymore
p.line(xAxis, yAxis, legend_label="data from AWS S3", line_width=2)
await Bokeh.embed.embed_item(ffi.to_js(json_item(p, "chart"))) #ffi converts a Python object into its JavaScript counterpart
await get_data()
</script>
</body>
</html>
```
Warning, if u previously used urllib or requests packages in Python, note, these packages do not work in Pyscript but Fetch does work. You will need to do some recoding if transitioning from urllib or requests.
Happy coding folks!

In the rapidly evolving landscape of web development, Spring WebFlux has emerged as a powerful tool for building reactive and non-blocking web applications. Introduced in Spring 5, WebFlux provides an alternative to the traditional Spring MVC framework, catering specifically to applications that require high concurrency and scalability. This blog aims to offer a detailed overview of Spring WebFlux, its key features, advantages, and practical use cases.
## What is Spring WebFlux?
Spring WebFlux is a framework designed to support the development of reactive web applications. It is part of the larger Spring ecosystem and is built on the foundations of Project Reactor, a library for building non-blocking applications on the JVM.
### Key Characteristics:
- **Reactive Programming**: Utilizes reactive programming principles to handle asynchronous data streams.
- **Non-Blocking I/O**: Supports non-blocking I/O operations, which leads to better resource utilization and scalability.
- **Backpressure**: Manages the flow of data to ensure that producers do not overwhelm consumers.
- **Declarative Syntax**: Employs a declarative style of coding, making the code more readable and maintainable.
## Core Concepts
### Reactive Streams
The backbone of Spring WebFlux is the Reactive Streams specification, which defines a standard for asynchronous stream processing with non-blocking backpressure. The four main interfaces of Reactive Streams are:
- **Publisher**: Emits a sequence of items to subscribers according to their demand.
- **Subscriber**: Consumes items emitted by the Publisher.
- **Subscription**: Represents a one-to-one lifecycle of a Subscriber subscribing to a Publisher.
- **Processor**: Represents a processing stage which is both a Subscriber and a Publisher.
### Project Reactor
Project Reactor is the reactive library that provides the necessary tools and operators to work with reactive streams in Spring WebFlux. It includes two main types:
- **Mono**: Represents a single, potentially empty, asynchronous value.
- **Flux**: Represents a sequence of asynchronous values.
### Router and Handler Functions
In Spring WebFlux, routing and handling requests can be done in a functional style. The main components are:
- **RouterFunction**: Defines a mapping between a request and a handler.
- **HandlerFunction**: Represents the code to handle the request.
Here's a simple example of a RouterFunction and HandlerFunction:
```java
@Configuration
public class RouterConfig {
@Bean
public RouterFunction<ServerResponse> route(Handler handler) {
return RouterFunctions.route(GET("/hello"), handler::hello);
}
}
@Component
public class Handler {
public Mono<ServerResponse> hello(ServerRequest request) {
return ServerResponse.ok().bodyValue("Hello, WebFlux!");
}
}
```
## Advantages of Spring WebFlux
### Improved Performance
WebFlux's non-blocking nature allows for better resource utilization, enabling the handling of a large number of requests with a smaller thread pool. This is particularly beneficial for applications with high concurrency requirements.
### Scalability
By avoiding thread blocking, WebFlux applications can scale more efficiently, making them suitable for microservices and cloud-native architectures.
### Better Responsiveness
Reactive programming enables handling of data streams more gracefully, resulting in improved responsiveness and user experience, especially in real-time applications.
### Flexibility
WebFlux supports both annotation-based and functional programming models, providing developers with the flexibility to choose the approach that best fits their needs.
## Practical Use Cases
### Real-Time Applications
Applications like chat systems, live notifications, and real-time data processing benefit significantly from WebFlux's reactive and non-blocking capabilities.
### Microservices
WebFlux is well-suited for microservices architectures, where services need to handle high loads and communicate efficiently.
### Streaming Data
WebFlux excels in scenarios involving streaming data, such as video streaming, live data feeds, and event-driven systems.
## Getting Started with Spring WebFlux
### Setting Up the Project
To get started with Spring WebFlux, you can create a new Spring Boot project with the necessary dependencies. You can do this using Spring Initializr or by manually adding dependencies to your `build.gradle` or `pom.xml` file.
Here's an example `pom.xml` configuration:
```xml
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
</dependency>
<!-- Other dependencies -->
</dependencies>
```
### Creating a Simple WebFlux Application
1. **Define the Router and Handler:**
```java
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.ServerRequest;
import org.springframework.web.reactive.function.server.ServerResponse;
import org.springframework.web.reactive.function.server.RouterFunctions;
import org.springframework.stereotype.Component;
import reactor.core.publisher.Mono;
import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
@Configuration
public class RouterConfig {
@Bean
public RouterFunction<ServerResponse> route(Handler handler) {
return RouterFunctions.route(GET("/hello"), handler::hello);
}
}
@Component
public class Handler {
public Mono<ServerResponse> hello(ServerRequest request) {
return ServerResponse.ok().bodyValue("Hello, WebFlux!");
}
}
```
2. **Run the Application:**
Create a main class to run the Spring Boot application:
```java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WebFluxApplication {
public static void main(String[] args) {
SpringApplication.run(WebFluxApplication.class, args);
}
}
```
### Testing the Application
To test the application, you can use tools like Postman or simply access `http://localhost:8080/hello` in your browser. You should see a response with "Hello, WebFlux!".
## Conclusion
Spring WebFlux is a powerful and flexible framework for building reactive and non-blocking web applications. Its emphasis on reactive programming and non-blocking I/O makes it well-suited for modern, high-performance web applications. Whether you are building real-time systems, microservices, or streaming data applications, WebFlux provides the tools and abstractions needed to develop scalable and responsive applications.
As you embark on your journey with Spring WebFlux, remember that the key to mastering it lies in understanding the reactive programming paradigm and leveraging the rich set of features offered by Project Reactor. With its growing popularity and community support, Spring WebFlux is poised to play a significant role in the future of web development. | fullstackjava |

However, this pervasive reliance on software also exposes individuals, businesses, and institutions to a myriad of security threats.
In this article, we delve into the intricate web of security threats that loom over software applications, exploring their nature, impact, and mitigation strategies.
Read also: [Transformation of Privacy in the Digital Age](https://infosafe24.com/posts/11-Ways-to-Improve-Security-of-Your-Online-Presence)
Software security threats encompass a broad spectrum of malicious activities aimed at exploiting vulnerabilities in software applications.
These threats pose significant risks to the confidentiality, integrity, and availability of data and systems.
Understanding the various types of security threats is crucial for developers, businesses, and users to implement effective countermeasures and safeguard against potential breaches.
## Malware
*Malware*, short for malicious software, represents one of the most pervasive and insidious threats to software applications. <br>
_viruses_, self-replicating programs that spread from one device to another,
worms, viruses exploiting network vulnerabilities to spread,<br>
_trojans_, disguised as legitimate software to trick you into installing them,
ransomware, Locks your files or system and demands a ransom payment to unlock them, and <br>
_spyware_, stealing your personal information without your knowledge,
are among the diverse array of malware that can infiltrate systems, compromise data, and disrupt operations.
**Phishing** emails are one of the most prevalent methods of malware infiltration, attackers craft emails that appear to be from legitimate sources like banks, credit card companies, or even familiar people.
These emails typically urge you to click on malicious links or download infected attachments.
Once clicked, the links can download malware directly, or they might take you to a compromised website booby-trapped with malware.
Unsecured downloads, software vulnerabilities, visiting compromised websites are some other methods for infiltration.
By being aware of these methods and practicing safe computing habits, you can significantly reduce the risk of malware infecting your computer system.

With evolving techniques and distribution methods, malware continues to evolve, posing a persistent challenge to cybersecurity professionals worldwide.
## Web Application Vulnerabilities
Web applications, with their ubiquitous presence and dynamic functionality, introduce unique security challenges.
SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and other vulnerabilities expose web applications to exploitation, data breaches, and unauthorized access.
**SQL injection** (SQLi) is a cyberattack that targets applications connected to databases. It exploits vulnerabilities in how the application handles user input. Attackers can inject malicious SQL code into forms, queries, or other data entry points to manipulate the database.
XSS, which stands for Cross-Site Scripting, is a type of security vulnerability exploited by attackers to inject malicious scripts into websites.
These scripts then run in the victim's web browser, potentially compromising their data or hijacking their session.
**CSRF**, also known as Cross-Site Request Forgery, is a web security vulnerability that allows attackers to trick users into performing unintended actions on a web application they're already authenticated to.
Imagine you're logged into your bank account (authenticated). An attacker tricks you into visiting a malicious website (crafted to trigger a CSRF attack).
In the background, without your knowledge or consent, this malicious website submits a request to your bank account (using your already authenticated session) - possibly a transfer request to the attacker's account!
Thes attacks exploit website vulnerabilities in the way it handles user input, such as data from comments sections, search bars, or user profiles. This flaw allows the attacker to inject malicious code without the website properly recognizing it.
The attacker also can insert malicious script disguised as regular user input into a vulnerable field on the website. This script could be written in JavaScript, HTML, or other languages that web browsers can understand.
When the victim visits the compromised webpage, their browser unknowingly executes the attacker's script. This can lead to various consequences depending on the attacker's goals.
As the primary interface for user interaction, securing web applications is paramount for protecting sensitive data and preserving user trust.
## Network-Based Threats
Network-based threats, such as Denial of service (DoS) and distributed denial of service (DDoS) attacks, target the availability of software applications by overwhelming network resources with malicious traffic.
DDoS stands for Distributed Denial-of-Service. It's a cyberattack that aims to disrupt the normal traffic of a website, service, or network by overwhelming it with a flood of internet requests.
Imagine a traffic jam so severe that no regular traffic can reach its destination. That's what a DDoS attack attempts to do in the digital world.
**There are various ways of execution:**
**Botnet Army**, attackers build an army of compromised devices, often called a botnet. These devices can be personal computers, smartphones, or even Internet-of-Things (IoT) gadgets that have been unknowingly infected with malware, giving the attacker control.
Command and Control, attacker remotely controls the botnet, issuing commands to launch the attack.
Flooding the Target, each infected device in the botnet sends a massive amount of fake traffic requests to the target website or service. This can be pings, HTTP requests, or other types of traffic.
A **man-in-the-middle** (MITM) attack is a cyberattack where the attacker secretly inserts themselves into the communication between two parties, allowing them to eavesdrop on the conversation or even alter the messages being exchanged. It's like a hidden listener on a phone call, able to hear both sides and potentially tamper with what's being said.
The attacker positions themself between the victim and the legitimate website or service they are trying to communicate with.
This can be achieved through various methods like:
Unsecured Wi-Fi Networks, attackers can set up fake Wi-Fi hotspots that appear legitimate, tricking users into connecting. Once connected, the attacker can intercept traffic between the user's device and the internet.
DNS Spoofing, the attacker redirects the victim's traffic to a malicious website that impersonates the real one.
ARP Spoofing, in a local network, the attacker tricks other devices into believing their machine is the intended recipient, allowing them to intercept communication.
## Insider Threats
Insider threats emanate from individuals within organizations who misuse their access privileges to compromise security. Whether through malicious intent, negligence, or coercion, insiders can steal sensitive data, sabotage systems, or facilitate external attacks.
Detecting and mitigating insider threats requires a combination of technical controls, policy enforcement, and employee education to safeguard against internal risks.
Turncoats: These individuals intentionally steal data, sabotage systems, or commit fraud for personal gain, revenge, or to benefit a competitor.
Disgruntled Employees: Employees who are unhappy with the company, facing termination, or have personal grievances might resort to malicious actions as a form of retaliation.
Careless Users: Employees who lack proper cybersecurity awareness or training might accidentally expose sensitive data through phishing attacks, weak passwords, or sharing information with unauthorized individuals.
Bypassing Security Controls: Intentionally or unintentionally circumventing security measures due to convenience or a lack of understanding about their importance.
These insiders can misuse their access intentionally (malicious) or unintentionally (negligent) to harm the organization.
## Internet of Things (IoT)
The proliferation of Internet-connected devices in the IoT ecosystem introduces new avenues for security threats.
Insecure IoT devices, lacking robust authentication, encryption, and update mechanisms, are susceptible to exploitation by malicious actors.
Internet of Things (IoT) devices, while bringing convenience and automation to our lives, introduce new security challenges.
These devices are often vulnerable due to several factors:
Limited Resources: Many IoT devices are designed with low power consumption and minimal cost in mind. This often leads to limited processing power, memory, and storage which can restrict robust security features.
Pre-configured Software and Firmware: Manufacturers sometimes pre-install software and firmware with default settings or weak passwords, making them easy targets for attackers to exploit known vulnerabilities.
Neglecting Updates: Unlike traditional computers, IoT devices may not have easy-to-use update mechanisms or automatic update functionality. Users might neglect to install critical security patches, leaving devices vulnerable to new threats.
Insecure Communication Protocols: Some IoT devices rely on outdated or unencrypted communication protocols, allowing attackers to intercept or manipulate data transmissions.
Lack of Device Management: Organizations might struggle to keep track of all their IoT devices, making it difficult to enforce security policies, deploy updates, or monitor for suspicious activity.
Compromised IoT devices can not only jeopardize user privacy and safety but also pose broader risks to critical infrastructure and public safety. Securing the IoT requires collaboration among manufacturers, regulators, and consumers to establish baseline security standards and best practices.
## Social Engineering
Despite advancements in cybersecurity awareness and education, social engineering remains a potent threat vector.
Social engineering is a deceptive technique used by attackers to manipulate individuals into divulging sensitive information, performing actions, or bypassing security measures. Unlike traditional hacking methods that rely on exploiting technical vulnerabilities, social engineering exploits human psychology and trust to achieve malicious objectives. It preys on emotions such as curiosity, fear, urgency, or greed to persuade targets to comply with the attacker's requests.
Phishing, pretexting, baiting, and other social engineering tactics prey on trust, curiosity, and ignorance to deceive users into divulging sensitive information or performing actions that compromise security.
Phishing is a technique when attackers send fraudulent emails, messages, or websites that mimic legitimate entities to trick recipients into disclosing personal information such as login credentials, credit card numbers, or account details.
Pretexting is creating a fabricated scenario or pretext to manipulate targets into providing information or performing actions. This may involve impersonating authority figures, such as IT support personnel or company executives, to gain trust and elicit sensitive information.
Attackers may impersonate trusted individuals or organizations, such as coworkers, IT staff, or service providers, to deceive targets into complying with their requests.
Attackers may offer enticing incentives, such as free downloads, prizes, or rewards, to lure targets into clicking on malicious links or downloading malware-infected files in a technique called baiting.
Social engineering attacks can have serious consequences, including data breaches, identity theft, financial loss, and reputational damage. To mitigate the risks of social engineering, organizations should invest in employee training and awareness programs to recognize and resist manipulation tactics. Additionally, implementing multi-factor authentication, establishing clear communication protocols, and maintaining a culture of skepticism can help defend against social engineering attacks.
## Emerging Threats
Emerging threats, such as zero-day exploits and advanced persistent threats (APTs), exploit unknown vulnerabilities to evade detection and bypass traditional security measures.
Zero-day exploits, also written as 0-day exploits, are a serious cybersecurity threat. They exploit vulnerabilities in software, hardware, or firmware that are unknown to the vendor or developer. This means there's no patch or security fix available yet, leaving systems vulnerable until a solution is developed.
Advanced persistent threats (APTs) are sophisticated cyberattacks unlike your typical hit-and-run malware infections. APT actors are well-funded and highly skilled groups (often state-sponsored) who target specific organizations for long-term strategic goals, such as stealing intellectual property, disrupting operations, or conducting espionage.
A proactive approach to threat intelligence, vulnerability management, and patching is essential for mitigating emerging security risks.
## Conclusion
In conclusion, the landscape of security threats to software applications is dynamic, multifaceted, and constantly evolving. From traditional malware to emerging zero-day exploits, the breadth and complexity of security challenges demand vigilance, collaboration, and innovation.
By adopting a holistic approach to cybersecurity, integrating robust technical controls, proactive threat intelligence, and user awareness, organizations can mitigate risks and fortify their defenses against evolving threats. Ultimately, safeguarding software applications is not merely a technological endeavor but a shared responsibility to protect digital assets, preserve trust, and uphold the integrity of the interconnected world we inhabit.

1,889,541 | CouchGO! — Enhancing CouchDB with Query Server Written in Go | Over the past month, I’ve been actively working on proof-of-concept projects related to CouchDB,... | 0 | 2024-06-15T12:37:57 | https://dev.to/kishieel/couchgo-enhancing-couchdb-with-query-server-written-in-go-304n | couchdb, nosql, go, database | Over the past month, I’ve been actively working on proof-of-concept projects related to CouchDB, exploring its features and preparing for future tasks. During this period, I’ve gone through the CouchDB documentation multiple times to ensure I understand how everything works. While reading through the documentation, I came across a statement that despite CouchDB shipping with a default Query Server written in JavaScript, creating a custom implementation is relatively simple and custom solutions already exist in the wild.
I did some quick research and found implementations written in Python, Ruby, or Clojure. Since the whole implementation didn’t seem too long, I decided to experiment with CouchDB by trying to write my own custom Query Server. To do this, I chose Go as the language. I haven’t had much experience with this language before, except for using Go templates in Helm’s charts, but I wanted to try something new and thought this project would be a great opportunity for it.
## Understanding the Query Server
Before starting work, I revisited the CouchDB documentation once more to understand how the Query Server actually works. According to the documentation, the high-level overview of the Query Server is quite simple:
> The Query server is an external process that communicates with CouchDB via the JSON protocol over a stdio interface and handles all design function calls […].
The structure of the commands sent by CouchDB to the Query Server can be expressed as `[<command>, <*arguments>]` or `["ddoc", <design_doc_id>, [<subcommand>, <funcname>], [<argument1>, <argument2>, …]]` in the case of design documents.
So basically, what I had to do was write an application capable of parsing this kind of JSON from STDIO, performing the expected operations, and returning responses as specified in the documentation. There was a lot of type casting involved to handle a wide range of commands in Go code. Specific details about each command can be found under the [Query Server Protocol](https://docs.couchdb.org/en/stable/query-server/protocol.html) section of the documentation.
One problem I faced here was that the Query Server should be able to interpret and execute arbitrary code provided in design documents. Knowing that Go is a compiled language, I expected to be stuck at this point. Thankfully, I quickly found the [Yeagi](https://github.com/traefik/yaegi) package, which is capable of interpreting Go code with ease. It allows creating a sandbox and controlling access to which packages can be imported in the interpreted code. In my case, I decided to expose only my package called `couchgo`, but other standard packages can be easily added as well.
## Introducing CouchGO!
As a result of my work, an application called CouchGO! emerged. Although it follows the Query Server Protocol, it is not a one-to-one reimplementation of the JavaScript version as it has its own approaches to handling design document functions.
For example, in CouchGO!, there is no helper function like `emit`. To emit values, you simply return them from the map function. Additionally, each function in the design document follows the same pattern: it has only one argument, which is an object containing function-specific properties, and is supposed to return only one value as a result. This value doesn't have to be a primitive; depending on the function, it may be an object, a map, or even an error.
To start working with CouchGO!, you just need to download the executable binary from my [GitHub repository](https://github.com/kishieel/couchdb-query-server-go), place it somewhere in the CouchDB instance, and add an environment variable that allows CouchDB to start the CouchGO! process.
For instance, if you place the `couchgo` executable into the `/opt/couchdb/bin` directory, you would add following environment variable to enable it to work.
```shell
export COUCHDB_QUERY_SERVER_GO="/opt/couchdb/bin/couchgo"
```
## Writing Functions with CouchGO!
To gain a quick understanding of how to write functions with CouchGO!, let’s explore the following function interface:
```go
func Func(args couchgo.FuncInput) couchgo.FuncOutput { ... }
```
Each function in CouchGO! will follow this pattern, where Func is replaced with the appropriate function name. Currently, CouchGO! supports the following function types:
- Map
- Reduce
- Filter
- Update
- Validate (validate_doc_update)
Let’s examine an example design document that specifies a view with map and reduce functions, as well as a validate_doc_update function. Additionally, we need to specify that we are using Go as the language.
```json
{
"_id": "_design/ddoc-go",
"views": {

"language": "go"
}
```
Now, let’s break down each function starting with the map function:
```go
func Map(args couchgo.MapInput) couchgo.MapOutput {
out := couchgo.MapOutput{}
out = append(out, [2]interface{}{args.Doc["_id"], 1})
out = append(out, [2]interface{}{args.Doc["_id"], 2})
out = append(out, [2]interface{}{args.Doc["_id"], 3})
return out
}
```
In CouchGO!, there is no emit function; instead, you return a slice of key-value tuples where both key and value can be of any type. The document object isn't directly passed to the function as in JavaScript; rather, it's wrapped in an object. The document itself is simply a hashmap of various values.
Next, let’s examine the reduce function:
```go
func Reduce(args couchgo.ReduceInput) couchgo.ReduceOutput {
out := 0.0
for _, value := range args.Values {
out += value.(float64)
}
return out
}
```
Similar to JavaScript, the reduce function in CouchGO! takes keys, values, and a rereduce parameter, all wrapped into a single object. This function should return a single value of any type that represents the result of the reduction operation.
Finally, let’s look at the Validate function, which corresponds to the `validate_doc_update` property:
```go
func Validate(args couchgo.ValidateInput) couchgo.ValidateOutput {
if args.NewDoc["type"] == "post" {
if args.NewDoc["title"] == nil || args.NewDoc["content"] == nil {
return couchgo.ForbiddenError{Message: "Title and content are required"}
}
return nil
}
if args.NewDoc["type"] == "comment" {
if args.NewDoc["post"] == nil || args.NewDoc["author"] == nil || args.NewDoc["content"] == nil {
return couchgo.ForbiddenError{Message: "Post, author, and content are required"}
}
return nil
}
return nil
}
```
In this function, we receive parameters such as the new document, old document, user context, and security object, all wrapped into one object passed as a function argument. Here, we’re expected to validate if the document can be updated and return an error if not. Similar to the JavaScript version, we can return two types of errors: `ForbiddenError` or `UnauthorizedError`. If the document can be updated, we should return nil.
For more detailed examples, they can be found in my GitHub repository. One important thing to note is that the function names are not arbitrary; they should always match the type of function they represent, such as `Map`, `Reduce`, `Filter`, etc.
## CouchGO! Performance
Even though writing my own Query Server was a really fun experience, it wouldn’t make much sense if I didn’t compare it with existing solutions. So, I prepared a few simple tests in a Docker container to check how much faster CouchGO! can:
- Index 100k documents (indexing in CouchDB means executing map functions from views)
- Execute reduce function for 100k documents
- Filter change feed for 100k documents
- Perform update function for 1k requests
I seeded the database with the expected number of documents and measured response times or differentiated timestamp logs from the Docker container using dedicated shell scripts. The details of the implementation can be found in my GitHub repository. The results are presented in the table below.
| Test | CouchGO! | CouchJS | Boost |
|-----------------------|---------:|---------:|------:|
| Indexing | 141.713s | 421.529s | 2.97x |
| Reducing | 7672ms | 15642ms | 2.04x |
| Filtering | 28.928s | 80.594s | 2.79x |
| Updating | 7.742s | 9.661s | 1.25x |
As you can see, the boost over the JavaScript implementation is significant: almost three times faster in the case of indexing, more than twice as fast for reduce and filter functions. The boost is relatively small for update functions, but still faster than JavaScript.
## Conclusion
As the author of the documentation promised, writing a custom Query Server wasn’t that hard when following the Query Server Protocol. Even though CouchGO! lacks a few deprecated functions in general, it provides a significant boost over the JavaScript version even at this early stage of development. I believe there is still plenty of room for improvements.
If you need all the code from this article in one place, you can find it in my [GitHub repository](https://github.com/kishieel/couchdb-query-server-go).
Thank you for reading this article. I would love to hear your thoughts about this solution. Would you use it with your CouchDB instance, or maybe you already use some custom-made Query Server? I would appreciate hearing about it in the comments.

Uma das bibliotecas mais populares para essa tarefa no ambiente Node.js é o Nodemailer. Neste artigo, vamos explorar o Nodemailer, mostrando como configurá-lo e utilizá-lo para enviar e-mails em suas aplicações.
## O que é o Nodemailer?
Nodemailer é uma biblioteca para Node.js que permite o envio de e-mails de forma simples e eficiente. Ele suporta diversos serviços de e-mail e protocolos, incluindo SMTP, OAuth2, Sendmail e outros. Criado por Andris Reinman, o Nodemailer tem sido amplamente adotado pela comunidade Node.js devido à sua facilidade de uso e flexibilidade.
## Instalando o Nodemailer
Para começar a usar o Nodemailer, primeiro você precisa instalá-lo em seu projeto Node.js. Você pode fazer isso utilizando o npm (Node Package Manager):
```bash
npm install nodemailer
```
## Configurando o Nodemailer
A configuração do Nodemailer é bastante direta. Aqui está um exemplo básico de configuração para enviar e-mails usando um serviço SMTP, como o Gmail:
```javascript
const nodemailer = require('nodemailer');
// Crie um transportador utilizando o serviço SMTP do Gmail
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'seuemail@gmail.com',
pass: 'suasenha'
}
});
```
Para garantir a segurança, é recomendável usar variáveis de ambiente para armazenar informações sensíveis como credenciais de e-mail. Veja como isso pode ser feito:
```javascript
require('dotenv').config();
const nodemailer = require('nodemailer');
// Crie um transportador utilizando variáveis de ambiente
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: process.env.EMAIL_USER,
pass: process.env.EMAIL_PASS
}
});
```
No arquivo `.env`:
```
EMAIL_USER=seuemail@gmail.com
EMAIL_PASS=suasenha
```
## Enviando E-mails
Depois de configurar o transportador, enviar e-mails é muito simples. Aqui está um exemplo de como enviar um e-mail:
```javascript
let mailOptions = {
from: 'seuemail@gmail.com',
to: 'destinatario@example.com',
subject: 'Assunto do E-mail',
text: 'Corpo do e-mail em texto simples',
html: '<h1>Corpo do e-mail em HTML</h1>'
};
transporter.sendMail(mailOptions, function(error, info){
if (error) {
return console.log(error);
}
console.log('E-mail enviado: ' + info.response);
});
```
Com isso, você enviou seu primeiro e-mail usando Nodemailer!
## Personalizando E-mails
O Nodemailer permite a personalização de e-mails de várias formas, incluindo o uso de templates. Você pode usar bibliotecas de templating como o Handlebars ou EJS para criar e-mails mais dinâmicos e atrativos.
Aqui está um exemplo usando Handlebars:
```javascript
const hbs = require('nodemailer-express-handlebars');
const path = require('path');
// Configure o Handlebars como motor de template
transporter.use('compile', hbs({
viewEngine: {
extName: '.hbs',
partialsDir: path.resolve('./views'),
defaultLayout: false
},
viewPath: path.resolve('./views'),
extName: '.hbs'
}));
let mailOptions = {
from: 'seuemail@gmail.com',
to: 'destinatario@example.com',
subject: 'Assunto do E-mail',
template: 'email', // Nome do arquivo de template
context: {
name: 'Nome do destinatário'
}
};
transporter.sendMail(mailOptions, function(error, info){
if (error) {
return console.log(error);
}
console.log('E-mail enviado: ' + info.response);
});
```
## Conclusão
O Nodemailer é uma ferramenta poderosa e flexível para enviar e-mails em aplicações Node.js. Com uma configuração simples e suporte a várias opções de personalização, ele pode ser a solução ideal para suas necessidades de envio de e-mails.
Se você está buscando aprimorar suas habilidades em desenvolvimento web e Node.js, recomendo seguir o [IamThiago-IT no GitHub](https://github.com/IamThiago-IT). Lá, você encontrará diversos projetos e tutoriais que podem ajudar em seu aprendizado.

1,889,537 | How to Publish Cypress Test Results to Azure Devops | Continuing on the integration between Cypress and Azure Devops, in this post I am going to share how... | 0 | 2024-06-15T12:26:40 | https://dev.to/cinthiabs/how-to-publish-cypress-test-results-to-azure-devops-4aah | azure, devops, cypress, tutorial | Continuing on the integration between **Cypress** and **Azure Devops**, in this post I am going to share how to publish test results!
If you found this article helpful, please leave a comment.❤️
Let's go!🚀
First of all, make sure your tests are in a **Git repository (“Repos”)** in Azure DevOps.
Next, we have to install the package [JUnit Reporter for Cypress](https://www.npmjs.com/package/cypress-junit-reporter) as a project dependency
```
$ npm install cypress-junit-reporter --save-dev
```
After that, in your Cypress test code, you need to configure the settings in the "cypress.config.js" file as follows:
```
reporter: 'mocha-junit-reporter',
reporterOptions: {
mochaFile: 'results/test-results-[hash].xml',
}
```
Then, we need to include in the file .gitignore the folder "**results**", because every execution generates a new file with a hash code.
Now, navigate to Pipelines. If you already have a configured pipeline, locate it and click on **Edit** to make changes.
In your pipeline editor within Azure DevOps, navigate to Tasks and use the search bar to find the task named "Publish Test Results".
Now, you'll configure the task:
1. Set the "Test result format" to **JUnit**.
2. Set the **path** to publish the test files.
3. Check the option to **merge test results**.
After configuring these settings, click on **Add** to add the task to your pipeline.
Now, the configuration has been added to the azure-pipeline.yml file.
Once you have saved the azure-pipeline.yml file, initiate the test build by clicking on **"Run Pipeline"** in Azure DevOps. This action will start the CI/CD pipeline and execute the defined tasks, including a new configuration for test publish results.
After running the test, navigate to the **"Test"** to see a summary about the test, including execution time, how many tests passed and how many failed.
A very useful feature is that when a test fails we can create a **"bug"** task with all the details in Azure Devops!
This is for today! If you have any questions, leave me a comment!

Jenkins is an open-source Java automation server used for software development lifecycle automation of repetitive operations. Being able to integrate with nearly all tools in the CI/CD pipeline with its many plugin support makes it a vital tool for developers and DevOps engineers.
## AWS EC2 Instance
- Go to AWS Console
- Instances(running)
- Launch instances
## Install Jenkins
<br />
Pre-Requisites:
- Java (JDK)
## Run the below commands to install Java and Jenkins
<br />
Install Java
``
sudo apt update
sudo apt install openjdk-11-jre
``
Verify Java is Installed
```
java --version
```
Now, you can proceed with installing Jenkins
```
curl -fsSL https://pkg.jenkins.io/debian/jenkins.io-2023.key | sudo tee \
/usr/share/keyrings/jenkins-keyring.asc > /dev/null
echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
https://pkg.jenkins.io/debian binary/ | sudo tee \
/etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins
```
<br />
### By default, Jenkins will not be accessible to the external world due to the inbound traffic restriction by AWS. Open port 8080 in the inbound traffic rules as show below.
Add inbound traffic rules as shown in the image:
<br />
<br />
## Login to Jenkins using the below URL:
<br />
http://<ec2-instance-public-ip-address>:8080 [You can get the ec2-instance-public-ip-address from your AWS EC2 console page]
After you login to Jenkins,
- Run the command to copy the Jenkins Admin Password - `sudo cat /var/lib/jenkins/secrets/initialAdminPassword`
- Enter the Administrator password
<br />
<br />
## Click on Install suggested plugins
<br />
<br />
Wait for the Jenkins to Install suggested plugins.
<br />
<br />
Create First Admin User or Skip the step.
<br />
<br />
Jenkins Installation is Successful. You can now starting using the Jenkins
<br />
<br />
## Install the Docker Pipeline plugin in Jenkins:
<br />
- Log in to Jenkins.
- Go to Manage Jenkins > Manage Plugins.
- In the Available tab, search for "Docker Pipeline".
- Select the plugin and click the Install button.
- Restart Jenkins after the plugin is installed.
<br />
<br />
Wait for the Jenkins to be restarted.
<br />
## Docker Slave Configuration
<br />
Run the below command to Install Docker
```
sudo apt update
sudo apt install docker.io
```
### Grant Jenkins user and Ubuntu user permission to docker daemon.
<br />
```
sudo su -
usermod -aG docker jenkins
usermod -aG docker ubuntu
systemctl restart docker
```
You can run the below command to check if docker is up and running:
```
docker run hello-world
```
<br />
<br />
Once you are done with the above steps, it is better to restart Jenkins.
```
http://<ec2-instance-public-ip>:8080/restart
```
The docker agent configuration is now successful.
## You can also refer my GitHub Repo:
```
https://github.com/SubodhBagde/Jenkins-Demo-Pipeline/tree/main
```
# A simple Jenkins pipeline to verify if the docker agent configuration is working as expected.
</br >
## Follow the steps to implement your first pipeline in Jenkins.
</br >
- Click on the New Item tab on the left side of your Jenkins UI. Give a name and select Pipeline option and click on OK.
</br >
</br >
- Now configure the pipeline as shown below in the image.
</br >
</br >
</br >
- Finally click on Build Now tab on the left to start the process.
</br >
</br >
- Here's the output, simply cick on the console output to view it.
</br >
# Multi Stage Multi Agent
</br>
Set up a multi stage jenkins pipeline where each stage is run on a unique agent. This is a very useful approach when you have multi language application
or application that has conflicting dependencies.
</br>
## Steps involved in it are pretty much similar to the previous one.
</br>
- You have to just replace the Script path my this folder name, as shown below.
</br >
</br >
- Run the following docker command to check whether the container has been build or not. You can see that once the execution is
done the Jenkins application automatically deletes the container.
</br >
```
docker ps
```
</br >
</br >
The Multi Stage Multi Agent process is successful.

1,889,534 | Bootstrap Crash Course: Get Started with Responsive Web Design | Bootstrap is a powerful front-end framework that helps you build responsive and mobile-first web... | 0 | 2024-06-15T12:18:18 | https://dev.to/igbojionu/bootstrap-crash-course-get-started-with-responsive-web-design-3mp4 |
Bootstrap is a powerful front-end framework that helps you build responsive and mobile-first web designs quickly and easily. Whether you're new to web development or looking to streamline your workflow, this crash course will get you up and running with Bootstrap in no time.
### What is Bootstrap?
Bootstrap is a free and open-source toolkit for developing with HTML, CSS, and JavaScript. It provides a collection of pre-designed components, like buttons, forms, and navigation bars, that you can easily integrate into your projects.
### Why Use Bootstrap?
- **Responsive Design**: Bootstrap's grid system ensures your layout adapts to various screen sizes, making your site mobile-friendly.
- **Consistency**: With a unified design language, Bootstrap makes it easy to maintain a consistent look across your website.
- **Ease of Use**: Pre-built components and utilities save time and effort.
- **Community Support**: Extensive documentation and a large user base mean you can find help and resources easily.
### Getting Started with Bootstrap
1. **Include Bootstrap in Your Project**
You can include Bootstrap via CDN (Content Delivery Network). Add the following links to the `<head>` section of your HTML file:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Bootstrap Crash Course</title>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet">
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@4.5.2/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<!-- Your content here -->
</body>
</html>
```
2. **The Bootstrap Grid System**
The grid system is the core of Bootstrap's responsive layout. It divides your page into rows and columns, making it easy to create layouts that adjust to different screen sizes.
```html
<div class="container">
<div class="row">
<div class="col-md-4">Column 1</div>
<div class="col-md-4">Column 2</div>
<div class="col-md-4">Column 3</div>
</div>
</div>
```
In this example:
- `.container` provides a responsive fixed-width container.
- `.row` creates a horizontal group of columns.
- `.col-md-4` creates three equal-width columns for medium-sized devices (≥768px).
3. **Common Bootstrap Components**
Bootstrap offers a variety of pre-built components that can be quickly integrated into your project:
- **Buttons**
```html
<button class="btn btn-primary">Primary Button</button>
<button class="btn btn-secondary">Secondary Button</button>
```
- **Navbar**
```html
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
<ul class="navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
</ul>
</div>
</nav>
```
- **Cards**
```html
<div class="card" style="width: 18rem;">
<img src="..." class="card-img-top" alt="...">
<div class="card-body">
<h5 class="card-title">Card title</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
<a href="#" class="btn btn-primary">Go somewhere</a>
</div>
</div>
```
4. **Responsive Images**
Bootstrap also helps make your images responsive with the `.img-fluid` class:
```html
<img src="image.jpg" class="img-fluid" alt="Responsive image">
```
5. **Utility Classes**
Utility classes in Bootstrap are pre-defined classes that allow you to style elements quickly without writing custom CSS.
- **Margins and Padding**
```html
<div class="mt-3 mb-3">Margin Top and Bottom</div>
<div class="pt-2 pb-2">Padding Top and Bottom</div>
```
- **Text Alignment**
```html
<p class="text-center">Centered Text</p>
<p class="text-right">Right-Aligned Text</p>
```
6. **Customizing Bootstrap**
Bootstrap can be customized by overriding its default styles. You can add your own CSS rules to tailor the appearance of your site:
```html
<style>
.custom-btn {
background-color: #ff6600;
color: white;
}
</style>
```
```html
<button class="btn custom-btn">Custom Button</button>
```
### Conclusion
Bootstrap is a versatile and powerful tool for web development, helping you create responsive, mobile-friendly websites with minimal effort. By mastering its grid system, components, and utilities, you can streamline your workflow and build beautiful web pages quickly.
Feel free to explore more about Bootstrap and experiment with different components and styles. The official Bootstrap [documentation](https://getbootstrap.com/docs/) is a great place to start for more in-depth information and examples.

### Implementation of LayoutElements Panel Vue Component
Previously, the LayoutElements Panel was in the `extra.vue` file.
First, I created a new Vue file for the LayoutElements Panel and moved the HTML part inside the `<template> <template/>` tag.
Since the original codebase used vanilla JavaScript for some DOM manipulation, I converted these to Vue's reactive properties.
```html
<div
v-for="(element, j) in group.elements"
class="icon subcircuitModule"
:key="`${i}-${j}`"
:id="`${group.type}-${j}`"
:data-element-id="j"
:data-element-name="group.type"
@mousedown="dragElement(group.type, element, j)"
>
<div class="icon-image">
<img :src="`/img/${group.type}.svg`" />
<p class="img__description">
{ element.label !== '' ? element.label : 'unlabeled' }}
</p>
</div>
</div>
```
Additionally, I moved all related styles into the `<style> <style/>` tag.

As data... | 0 | 2024-06-15T12:11:24 | https://dev.to/kamomkoyan2/demystifying-big-o-notation-a-deep-dive-into-algorithm-efficiency-4g8o | ## Introduction
In the world of computer science and programming, efficiency is key. As data sets grow larger and software becomes more complex, understanding how algorithms perform and scale is crucial. One of the fundamental tools for analyzing the efficiency of algorithms is Big O notation. In this article, we will explore what Big O notation is, why it’s important, and how to use it to evaluate the performance of algorithms. We will also dive into some common examples to illustrate these concepts in action.
### What is Big O Notation?
Big O notation is a mathematical notation used to describe the upper bound of an algorithm’s running time or space requirements in terms of the size of the input data (denoted as n ). It provides a high-level understanding of the algorithm’s efficiency by focusing on the dominant term, ignoring constant factors and lower-order terms.
## Why is Big O Notation Important?
1. Scalability: Big O notation helps us understand how an algorithm will perform as the input size grows. This is crucial for applications that need to handle large data sets efficiently.
2. Comparison: It allows us to compare the efficiency of different algorithms independently of hardware and implementation details.
3. Optimization: By identifying the parts of an algorithm that contribute the most to its running time, we can focus our optimization efforts more effectively.
### Understanding Common Big O Notations
1.O(1) - Constant Time Complexity: An algorithm with constant time complexity will always execute in the same time regardless of the size of the input data. Example: Accessing an element in an array by index.
```
public class ConstantTimeExample {
public static int getElement(int[] arr, int index) {
return arr[index];
}
}
```
2.O(log n) - Logarithmic Time Complexity: Algorithms with logarithmic time complexity reduce the problem size with each step. Example: Binary search.
```
public class BinarySearch {
public static int binarySearch(int[] arr, int target) {
int low = 0;
int high = arr.length - 1;
while (low <= high) {
int mid = (low + high) / 2;
if (arr[mid] == target) {
return mid;
} else if (arr[mid] < target) {
low = mid + 1;
} else {
high = mid - 1;
}
}
return -1;
}
}
```
3.O(n) - Linear Time Complexity: An algorithm with linear time complexity grows directly in proportion to the size of the input data. Example: Finding the maximum element in an array.
```
public class LinearTimeExample {
public static int findMax(int[] arr) {
int max = arr[0];
for (int num : arr) {
if (num > max) {
max = num;
}
}
return max;
}
}
```
4.O(n log n) - Linearithmic Time Complexity: Common in efficient sorting algorithms like Merge Sort and Quick Sort.
```
public class MergeSort {
public static int[] mergeSort(int[] arr) {
if (arr.length <= 1) {
return arr;
}
int mid = arr.length / 2;
int[] left = mergeSort(Arrays.copyOfRange(arr, 0, mid));
int[] right = mergeSort(Arrays.copyOfRange(arr, mid, arr.length));
return merge(left, right);
}
private static int[] merge(int[] left, int[] right) {
int[] result = new int[left.length + right.length];
int i = 0, j = 0, k = 0;
while (i < left.length && j < right.length) {
if (left[i] <= right[j]) {
result[k++] = left[i++];
} else {
result[k++] = right[j++];
}
}
while (i < left.length) {
result[k++] = left[i++];
}
while (j < right.length) {
result[k++] = right[j++];
}
return result;
}
}
```
5.O(n^2) - Quadratic Time Complexity: Often seen in algorithms with nested loops. Example: Bubble Sort.
```
public class BubbleSort {
public static int[] bubbleSort(int[] arr) {
int n = arr.length;
for (int i = 0; i < n - 1; i++) {
for (int j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
return arr;
}
}
```
6.O(2^n) - Exponential Time Complexity: Algorithms with exponential time complexity double with each addition to the input size. Example: Recursive Fibonacci calculation.
```
public class Fibonacci {
public static int fibonacci(int n) {
if (n <= 1) {
return n;
}
return fibonacci(n - 1) + fibonacci(n - 2);
}
}
```
7.O(n!) - Factorial Time Complexity: Typically seen in algorithms that generate all permutations of a set.
```
public class Permutations {
public static void permutations(char[] arr, int step) {
if (step == arr.length) {
System.out.println(String.valueOf(arr));
return;
}
for (int i = step; i < arr.length; i++) {
char[] arrCopy = arr.clone();
char temp = arrCopy[step];
arrCopy[step] = arrCopy[i];
arrCopy[i] = temp;
permutations(arrCopy, step + 1);
}
}
}
```

We use it for example... | 0 | 2024-06-15T12:02:59 | https://dev.to/mknasiecki/scheduled-stepdown-for-smoother-mongodb-primary-election-4n0p | mongodb | Stepdown is a great tool that allows us to keep clusters operating smoothly. We use it for example when we want to perform some maintenance work on the host where the primary is currently running, to perform a rolling upgrade, and in many other cases we need to switch the primary to another node.
While usually electing a new primary is fast enough, for clusters with very high write traffic, it sometimes unfortunately leads to write errors on the application side. The reason is that drivers need to disconnect from the previous primary and connect to the new one, and this takes time. All write attempts at this time end with an error. Of course those operations can be retried after a short time, but it seems to me that this situation could be avoided fairly easily.
Here's my idea:
- We add an optional parameter to the stepDown method, let’s name it: `electionEffectiveTimeSeconds`. If we do not set it, stepDown works normally - as before,
- The new primary is elected, but the cluster and drivers do not use it as a primary yet, instead they wait for electionEffectiveTimeSeconds seconds after the election is done,
- Until then, the previous primary handles write operations,
- In the meantime, all cluster nodes and drivers receive information about the new primary and when the change will take effect - based on electionEffectiveTimeSeconds,
- This will allow all parties to properly prepare for the switchover, which should minimize the time of unavailability of the primary,
When the time expires, clusters and drivers change primaries to the new node.
The key element will be to determine the optimal range for this new parameter. On the one hand, it must be big enough to give enough of time to spread the information through the cluster and drivers. On the other hand, it must not be too long, because there is a risk that - during that time - the new elected primary will catch a lag and will not be able to become a primary. In this case, however, it could try one more time, and if that too fails, then perform a normal stepdown a third time.
I think this method would be useful during all stepdowns, which are planned in advance and it is not necessary to happen immediately.
I am curious about your opinions, if you see value in this, I will be grateful for the upvote [here](https://feedback.mongodb.com/forums/924280-database/suggestions/48541538-scheduled-stepdown-for-smoother-primary-election).

As a result, this way of creating significantly cuts down on development duration and costs as well as leads to more imaginative designs.
Virtual prototypes can be adjusted and tested under different conditions that provide important information about areas for improvement or potential problems. Such details facilitate the process of iteration, making it faster for companies to introduce high-quality products onto the market. The animated presentations made through 3D can also be used by stakeholders or capitalists to show these prototypes to them in an attractive manner.
4. Facilitating Collaboration And Communication
In product development, effective communication and collaboration are vital, particularly among teams that are located far apart geographically. It has been observed that through 3D animation, which is more like a universal language, different departments can be bridged together with their stakeholders. Elaborate animations will transmit intricate ideas concerning designs using simple terms, thereby minimizing confusion by ensuring everyone is on board.
Marketing teams can learn about technical specifications from engineering teams using 3D animations; hence product features come out clearly in promotional materials. This simplified form of communication promotes both efficacy and inventiveness of all involved parties.
5. Virtual And Augmented Reality Apps
The integration of 3d video animation services with virtual reality (VR) and augmented reality (AR) is another frontier that businesses are exploring. AR apps can let customers see products in their own place before buying them. Such interaction levels can greatly improve the shopping experience and reduce returns.
## Conclusion
The democratization of 3D animation is going to have its trajectory maintained. This will be driven by continued improvements in technology and increased availability. As software starts becoming more user-friendly and cheaper, even the fewest businesses can make use of 3D animation. Still, AI and machine learning advancements are predicted to simplify the process of creating animations, making them more efficient and cost-effective.
In sum, all business enterprises are profoundly affected daily by 3D animations. It does this by enhancing marketing efforts, leading to improved product development, customer education, and engagement. Though it evolves, this democratization of technology will continue empowering brands to innovate their products and keep up with competition where existence is dependent on thriving in the digital world.
## Key Takeaways
Businesses benefit from dynamic content created through 3D animation because they improve marketing engagement and social media visibility.
Virtual prototyping is another area that benefits from 3D animation since it cuts costs while augmenting innovativeness for collaborations among stakeholders.

1,889,491 | How to Easily Add Translations to Your React Apps with i18next | Multilingual support is a crucial aspect of modern web applications. By providing translations in... | 0 | 2024-06-15T11:07:10 | https://10xdev.codeparrot.ai/adding-translations-to-react-apps | react, translations, i18next, javascript | Multilingual support is a crucial aspect of modern web applications. By providing translations in multiple languages, you can cater to a diverse audience and enhance user experience. React applications can benefit significantly from internationalization libraries like i18next, which simplify the process of adding translations to your app.
This also means that you can easily switch between languages without reloading the page, making your app more user-friendly and accessible. In this article, we'll explore how to add translations to your React applications using i18next and create a seamless multilingual experience for your users.
## What is i18next?
[i18next](https://www.i18next.com/) is a popular internationalization library for JavaScript applications. It provides a robust framework for managing translations, formatting dates, numbers, and handling pluralization. i18next supports multiple backends for storing translations, making it versatile and adaptable to various project requirements.
## Getting Started with i18next in React
Let's get started by creating a new React application using Vite, a modern build tool that offers fast development and optimized production builds.
```bash
npm create vite@latest
```
Next, enter the project directory and install the necessary dependencies:
```bash
npm install
npm install i18next react-i18next i18next-http-backend i18next-browser-languagedetector
```
The `i18next` package is the core library, while `react-i18next` provides React bindings for i18next. The `i18next-http-backend` package allows loading translations from a remote server, and `i18next-browser-languagedetector` detects the user's preferred language based on the browser settings.
To start out, here's my `App.jsx` file:
```javascript
import './App.css';
function App() {
return (
<div className="app">
<header className="app-header">
<h1>Welcome to My Multilingual App</h1>
<p>Learn how to add translations to your React app easily and efficiently.</p>
</header>
<main className="app-main">
<section className="content-section">
<h2>About This Tutorial</h2>
<p>
This tutorial will guide you through the steps needed to integrate translations into your React application.
By the end of this tutorial, you will be able to provide a seamless multilingual experience to your users.
</p>
</section>
<section className="content-section">
<h2>Why Add Translations?</h2>
<p>
Adding translations to your app allows you to reach a broader audience. In today's globalized world,
it's crucial to make your content accessible to users who speak different languages.
</p>
</section>
<section className="content-section">
<h2>Getting Started</h2>
<p>
To get started with translations, we will use a popular library called <strong>react-i18next</strong>.
This library provides all the tools you need to translate your app's content.
</p>
</section>
</main>
<footer className="app-footer">
<p>© 2024 My Multilingual App. All rights reserved.</p>
</footer>
</div>
);
}
export default App;
```
It just has some placeholder content for now. We'll add translations to this app shortly.
## Setting Up i18next
To configure i18next in your React application, create a new file called `i18n.js` in the `src` directory:
```javascript
import i18next from "i18next";
import { initReactI18next } from "react-i18next";
import LanguageDetector from "i18next-browser-languagedetector";
import HTTPApi from "i18next-http-backend";
i18next
.use(initReactI18next)
.use(LanguageDetector)
.use(HTTPApi)
.init({
fallbackLng: "en",
interpolation: {
escapeValue: false,
},
});
export default i18next;
```
In the i18n.js file, we have several key components to set up i18next for our React application:
- **Importing i18next and its dependencies:** We start by importing the core i18next library, along with its React bindings, language detector, and HTTP backend.
- **Using the React integration:** initReactI18next provides the integration for using i18next with React.
- **Using the language detector:** LanguageDetector helps detect the user's preferred language based on their browser settings.
- **Using the HTTP backend:** HTTPApi allows loading translations from a remote server.
- **Initializing i18next:** The init function configures i18next with a fallback language (English in this case) and sets interpolation options.
This setup ensures that i18next is properly configured to handle translations and detect the user's preferred language.
## Loading Translations
Next, we'll create translation files for different languages. In the `public` directory, create a new folder called `locales` and add subfolders for each language you want to support, such as `en` for English and `fr` for French. Inside each language folder, create a `translation.json` file with the respective translations.
Here's an example of the `translation.json` file for English `(public/locales/en/translation.json)`:
```json
{
"welcome_message": "Welcome to My Multilingual App",
"tutorial_intro": "Learn how to add translations to your React app easily and efficiently.",
"about_this_tutorial": "About This Tutorial",
"about_this_tutorial_text": "This tutorial will guide you through the steps needed to integrate translations into your React application. By the end of this tutorial, you will be able to provide a seamless multilingual experience to your users.",
"why_add_translations": "Why Add Translations?",
"why_add_translations_text": "Adding translations to your app allows you to reach a broader audience. In today's globalized world, it's crucial to make your content accessible to users who speak different languages.",
"getting_started": "Getting Started",
"getting_started_text": "To get started with translations, we will use a popular library called react-i18next. This library provides all the tools you need to translate your app's content."
}
```
And for French `(public/locales/fr/translation.json)`:
```json
{
"welcome_message": "Bienvenue dans mon application multilingue",
"tutorial_intro": "Apprenez à ajouter des traductions à votre application React facilement et efficacement.",
"about_this_tutorial": "À propos de ce tutoriel",
"about_this_tutorial_text": "Ce tutoriel vous guidera à travers les étapes nécessaires pour intégrer des traductions dans votre application React. À la fin de ce tutoriel, vous serez en mesure de fournir une expérience multilingue transparente à vos utilisateurs.",
"why_add_translations": "Pourquoi ajouter des traductions?",
"why_add_translations_text": "Ajouter des traductions à votre application vous permet de toucher un public plus large. Dans le monde globalisé d'aujourd'hui, il est crucial de rendre votre contenu accessible aux utilisateurs qui parlent différentes langues.",
"getting_started": "Commencer",
"getting_started_text": "Pour commencer avec les traductions, nous allons utiliser une bibliothèque populaire appelée react-i18next. Cette bibliothèque fournit tous les outils nécessaires pour traduire le contenu de votre application."
}
```
These translation files contain key-value pairs for each translation string. We'll use these translations to display content in different languages based on the user's preference.
## Using Translations in Your App
Now that we have set up i18next and loaded translations for different languages, let's integrate them into our React application
First, make sure to import and initialize i18next at the entry point of your application in `main.jsx`:
```javascript
import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'
import './index.css'
import './i18n.js'
ReactDOM.createRoot(document.getElementById('root')).render(
<React.StrictMode>
<App />
</React.StrictMode>,
)
```
Next, update your `App.jsx` file to use the `useTranslation` hook provided by `react-i18next`:
```javascript
import './App.css';
import { useTranslation } from 'react-i18next';
function App() {
const { t } = useTranslation();
return (
<div className="app">
<header className="app-header">
<h1>{t('welcome_message')}</h1>
<p>{t('tutorial_intro')}</p>
</header>
<main className="app-main">
<section className="content-section">
<h2>{t('about_this_tutorial')}</h2>
<p>{t('about_this_tutorial_text')}</p>
</section>
<section className="content-section">
<h2>{t('why_add_translations')}</h2>
<p>{t('why_add_translations_text')}</p>
</section>
<section className="content-section">
<h2>{t('getting_started')}</h2>
<p>{t('getting_started_text')}</p>
</section>
</main>
<footer className="app-footer">
<p>© 2024 My Multilingual App. All rights reserved.</p>
</footer>
</div>
);
}
export default App;
```
The `useTranslation` hook provides access to the `t` function, which we use to translate the content based on the key specified in the translation files. By calling `t('key')`, we can retrieve the corresponding translation string for that key.
## Switching Between Languages
To enable users to switch between languages, we can add a language selector to our app. Here's an example of how you can implement a language switcher using the `i18next` instance:
```javascript
import './App.css';
import { useTranslation } from 'react-i18next';
function App() {
const { t, i18n } = useTranslation();
const changeLanguage = (lng) => {
i18n.changeLanguage(lng);
};
return (
<div className="app">
<header className="app-header">
<h1>{t('welcome_message')}</h1>
<p>{t('tutorial_intro')}</p>
<div className="language-selector">
<button onClick={() => changeLanguage('en')}>English</button>
<button onClick={() => changeLanguage('fr')}>Français</button>
</div>
</header>
<main className="app-main">
<section className="content-section">
<h2>{t('about_this_tutorial')}</h2>
<p>{t('about_this_tutorial_text')}</p>
</section>
<section className="content-section">
<h2>{t('why_add_translations')}</h2>
<p>{t('why_add_translations_text')}</p>
</section>
<section className="content-section">
<h2>{t('getting_started')}</h2>
<p>{t('getting_started_text')}</p>
</section>
</main>
<footer className="app-footer">
<p>© 2024 My Multilingual App. All rights reserved.</p>
</footer>
</div>
);
}
export default App;
```
With this implementation, users can switch between English and French by clicking the respective language buttons. The `changeLanguage` function changes the language based on the selected locale.
If you've followed along, you should now have a React application with multilingual support using i18next. Here is a preview of the app in English and French:
## Fall Back to Default Language
In the event that a translation is missing for a specific key, i18next will fall back to the default language specified in the configuration. This ensures that users always see content, even if translations are missing for a particular language.
For example, let's add a button for a language that doesn't have translations in our app:
```javascript
<div className="language-selector">
<button onClick={() => changeLanguage('en')}>English</button>
<button onClick={() => changeLanguage('fr')}>Français</button>
<button onClick={() => changeLanguage('es')}>Español</button>
</div>
```
Since we haven't provided translations for Spanish, i18next will fall back to the default language (English) when the user selects Spanish.
By adding translations to your React applications, you can provide a seamless multilingual experience to users around the world. i18next simplifies the process of managing translations and ensures that your app is accessible to a diverse audience.
I hope this tutorial has been helpful in guiding you through the process of adding translations to your React apps. Happy coding! | harshalranjhani |

1,531,140 | Hexaflare: Exploring Data Structures | I initially got into programming because I wanted to make a game, and although I do web development... | 0 | 2024-06-15T10:16:01 | https://dev.to/gazayas/hexaflare-exploring-data-structures-1ond | javascript, css, datastructures, algorithms | I initially got into programming because I wanted to make a game, and although I do web development now, I got the chance to create a game with vanilla JavaScript and CSS called Hexaflare which I made back in early 2020. It was one of the most fun programming projects I've ever worked on, and the main idea of it came to me when I was studying data structures and algorithms.
I don't consider myself a very good programmer, and there are a lot of problems with the code itself because it was more of an idea that I wanted to put on paper as a side project. I used a lot of global variables, I didn't use import/export statements to manage modules, and all around there's a lot that could be cleaned up. Either way writing the code was a lot of fun, but besides that, having a goal in mind, envisioning how to solve it from an abstract perspective first, and THEN applying those principles in code form was such a fun process that I wanted to write about it.
# Table of Contents
1. What is Hexaflare?
2. Hexagons in Nature
3. Hexagonal Tile Pattern (Data Structure?)
4. Flare Star UI: Writing the Tile Pattern dynamically
5. Embarking into the Unknown: Moving and Rotating Star Clusters
6. Simulating Gravity
7. Almost Giving Up
8. Flare: Clearing Rings when Filled
9. Timer, Levels, and Final Implementation<br/>
10. ★ Code Blooper Compilation
# 1. What is Hexaflare?
Hexaflare is a Tetris-like puzzle game in which you move blocks (star clusters) around the game board (the flare star), and then drop them to create rings. Whenever you create a ring the blocks disappear (like when you make a line in Tetris), and the remaining pieces gravitate toward the center.
Play it here! https://hexaflare.fly.dev
I knew that I wanted to make a fast-paced puzzle game, but the initial idea wasn't to actually include a gravity mechanic or be anything similar to Tetris. I primarily wanted the player to move pieces freely across the board, but I thought that was too easy. That's when Tetris came to mind, and I thought it would be cool to add a gravity mechanic instead.
The idea came to me at night when I had the lights off right before I was about to go to bed. I took out my phone and started writing notes like crazy. It was a rush of inspiration, and I had so much momentum that I finished writing most of the logic in a few weeks. (There was a bug that almost made me give up on the project, but I'll get to that later in section 7). I took all my notes, and the next day I started working through what abstractions would be necessary to make the game a reality.
# 2. Hexagons in Nature
Before I actually get into the details of how I made the game, I just want to say that hexagons tend to show up a lot in nature, and they're pretty cool. Without getting too much into it, I suggest watching [this video](https://www.youtube.com/watch?v=Pypd_yKGYpA) which talks about honeycombs, hexagonal rock formations, and hexagonal insect eyes. Honeycombs, for example, show that hexagons are the shape that provide bees with the most space for storing honey, shown by [this video](https://www.youtube.com/watch?v=kxDEcODUEP0) which also talks about the [honeycomb conjecture](https://en.wikipedia.org/wiki/Honeycomb_conjecture), a mathematical expression of the same concept. I gained a new appreciation for hexagons in nature by working on this project, so I thought it was worth mentioning here before I started explaining how I made the game.
# 3. Hexagonal Tile Pattern (Data Structure?)
Before the idea to make this game came to me that one night, I had actually been studying heap data structures at the time using [this app](http://algorithm.wiki/ja/app/?fbclid=IwAR07YaXmx7kTjaJ-RgoPEO1RF8w4qfnC_I30Ub0BATvFx4sR-cfzwx8TwrQ#0). Without showing any code, it had a visualization of how to populate and pop values off of max heaps.
In a max heap, the root is the biggest value in the set of data.
Let's see how values are handled when populating a max heap from a set of data. In the app's visualization, you can see that each value is added one by one.
You can see here that 2 is added underneath 5. It remains as a child node to 5 because 5 is a larger value. Let's see what happens when we append 7.
As a rule we append it as a child, but each time we add a new element, we sort the set of data by comparing the parent and child. We then switch them if the child is a larger value, thus ensuring that the root of the set of data is always the largest value. So, here we switch 7 and 5.
What I found so interesting about this is that it resembled gravity if you were to turn it on its head. In other words, the largest value would always "drop to the bottom" so to speak. That's when the idea sparked in my mind to create Hexaflare, and I wanted to create a data structure that would not just spread out two child nodes at a time, but that would fan out in a 360 degree fashion.
Before I get to the prototypes, here's what the structure looks like. I found that each ring should have its own array, so the final product turned out to be a two-dimensional array.
```ruby
[
[1] # The center (root) of the pattern.
[1, 2, 3, 4, 5, 6], # Ring 1
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12], # Ring 2
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18] # Ring 3
]
```
So, my journey to create this structure began. Since I had never seen anything like it before and I had no idea what it would actually look like at first, some of the prototypes were...interesting, to say the least.
The first idea I had was to make the structure look as close to a heap (or other data structures for that matter) as possible. That meant that the root would be at the top, and the child nodes would trickle downwards. You can see that in the screenshot above, and also in this one:
This was definitely getting closer to what I envisioned. It starts with a root, 1, and then fans out to 6 child nodes which represent one ring. As you go down each child, you start to see something peculiar about the rings. Whereas the first ring has six elements (1 through 6) the second ring has 12 elements. Then, the following ring has 18 elements. I had found a new abstraction in the pattern: Every successive ring increases by exactly 6.
Still, this structure really bothered me because it was mentally hard to grasp when trying to envision it as an actual, visual hexagonal tile pattern. It was at this point where I decided I needed to break out of the box of having a "top down" style data structure, and just let it be what it actually was; a pattern that extended in all directions two-dimensionally. That's when I came up with this pattern.
As you can see here, the first ring only has 6 elements, but when we get to the second ring, the following child nodes fan out to the <bold>side</bold>. Here is where I found a new abstraction the hexagon tile pattern. I found two abstractions that I called "Corner Hexagon" and "Side Hexagon." A corner hexagon is any hexagon that extends on a line directly from the root (In the screenshot above, you can see that the number 1 extends consistently to the right. This is the first Corner Hexagon in the ring, and each ring has a total of 6 Corner Hexagons). A Side Hexagon is anything else that is not a Corner Hexagon (Extends to the side away from the Corner Hexagon).
Without getting into the details of how to find parent nodes, etc., this two dimensional array was eventually what I came up with to implement the gravity mechanic which takes a leaf node and traces it all the way to the root, and it was just a lot of fun to think through the process and experiment. I can say that I genuinely enjoyed learning about data structures like heaps and then applying similar concepts to my own code.
# 4. Flare Star UI: Writing the Tile Pattern dynamically
Now that we have the structure, we can create it dynamically based on how many rings we want like this:
```JavaScript
function generateFlareStar(number_of_rings) {
// Generate Core (root)
var core = 1
// `flare_star` is the hexagonal tile pattern we'll be returning.
var flare_star = [[core]]
// The rings start from the second step
// (In other words, the core itself isn't a ring)
// `level` represents how many levels deep the structure is.
var level = core + number_of_rings
for(var i = 1; i < level; i++) {
// Generate new ring
var ring = []
// Here we're just populating each array with numbers.
// 1-6 for ring 1, 1-12 for ring 2, 1-18 for ring 3, etc.
for(var value = 1; value <= i * 6; value++) {
ring.push(value)
}
flare_star[i] = ring
}
return flare_star
}
```
The difficulty of mapping this out in CSS was that all of the pixels had to be determined dynamically when generating each hexagon. I eventually ended up with the following two functions:
```JavaScript
// This generates the array
// 12 here determines how many rings the structure has
flare_star = generateFlareStar(12)
// This generates the CSS
generateFlareStarUI(numberOfRings(flare_star))
```
In the example below, the game board starts with 12 rings, then I change it to 7 and refresh the page to make the size change.
# 5. Embarking into the Unknown: Moving and Rotating Star Clusters
This was absolutely the most difficult part of the development process, and I had no idea how to even start envisioning it to make it a possibility. Basically, I wanted to take these blocks, move them around the outside of the game board, and rotate them like in Tetris. Here's what some of those blocks look like.
I sat at my desk for about half an hour just thinking. Then I felt overwhelmed so I laid down on the floor for about another half an hour staring at the ceiling trying to figure out how to pull this thing off. Then I got a wave of inspiration and got to work.
I ended up coming up with a Mapping abstraction that takes a map of the block and rotates the entire block of hexagons according to that map.
The map itself keeps track of every hexagon, and has data concerning where it's supposed to move next. For example, this is a portion from one of the block types called Pleiades, a straight line of four hexagons:
```js
const PLEIADES_DATA = {
...
"hexagon_2": {
"center_of_gravity": true,
"rotation_pattern": {
"position_1": [["left", 1]],
"position_2": [["up_left", 1]],
"position_3": [["up_right", 1]],
"position_4": [["left", 2]],
"position_5": [["up_left", 2]],
"position_6": [["up_right", 2]],
}
},
"hexagon_3": {
"center_of_gravity": false,
"rotation_pattern": {
"position_1": [["left", 2]],
"position_2": [["up_left", 2]],
"position_3": [["up_right", 2]],
"position_4": [["left", 1]],
"position_5": [["up_left", 1]],
"position_6": [["up_right", 1]],
}
},
...
}
```
Each `position_1` here for example represents the first position of each hexagon for the entire block. So, when rotating a block to `position_2`, we get the x and y values from the original `div` elements and pass the block data to the Mapper to calculate the new coordinates, thus rotating the entire block appropriately. If you're interested, you can check out the Mapper [here](https://github.com/gazayas/hexaflare/blob/main/javascript/mapping.js).
There is a method in the code base called `rotate` which has some more logic to make this a reality. It calls a method named `getCoordinatesByMap` which can be found in the file linked to above, and this was by far the most brain-twisting part of the project. Still, I found it to be pretty fun even though it took a while to get it working properly.
# 6. Simulating Gravity
As I started to work on the gravity mechanic, I ran into a peculiar issue. I found that, when trying to move a block of four hexagons to the center, the hexagons started to fly in different directions. This was because, although all of the hexagons were moving toward the center, each hexagon didn't have the same parent, so whereas one hexagon might move downwards to the left diagonally, another might move downwards to the __right__ diagonally. What I decided to do was determine the direction the __entire__ block shifts in according to one hexagon, which I called the center of gravity. In doing so, the entire block would move in the same direction, solving the issue. You can see in the pleiades data above that there is a boolean value which designates if the hexagon is the center of gravity or not. If you're interested in how the logic works, you can see the source code [here](https://github.com/gazayas/hexaflare/blob/main/javascript/gravity.js).
# 7. Almost Giving Up
There was one point where I ran into a bug that for the life of me I couldn't figure out. I implemented collision logic, so whenever you drop a block it gravitates toward the center, and if there is another block standing in its way, the block stops moving. The problem was that, very rarely, the block would move down one more ring, overlapping other blocks.
I looked at the collision logic over and over again and couldn't find any issues. Granted, not writing tests was totally my fault... To be 100% honest, I wasn't sure HOW to write tests for logic like this, and since I was doing this as a side project on my own, I figured it would be okay with out it. Lesson learned.
Anyways, I spent about a good two weeks (maybe even longer) trying to figure this bug out, and I made absolutely no progress during that time. I was so discouraged that I even started to remake the project in Unity. As I started from scratch, I realized it would take too long, so I sat down with the original code again.
I eventually found out that the problem was with the gravity logic, and that the `while` loop I had which pulled the block closer to the center with each call needed to be called as a `do` block instead, checking the `while` condition at the END of the loop.
```js
do {
// Gravitation logic...
gravitation_direction = getGravitationDirection(center_of_gravity)
} while(gravitation_direction != null && starClusterCanGravitateToCore(star_cluster, gravitation_direction))
```
It was frustrating that the bug was being caused by just one conditional that should've been on a different line, but I'm so glad I was able to figure it out and get this project across the finish line.
# 8. Flare: Clearing Rings when Filled
Now that the gravity and collision mechanics were working, the last big step was to clear the rings and rack up the score. Similar to making a line in Tetris, first we check if any full rings exist, and if they do, we call the `flare` method (which simply removes the hexagons) and we add 1 to the total flare count which checks if we should level up or not.
```js
while(fullRingExists(flare_star_rings)) {
// Flare 💫🔥
for (var i = 0; i < flare_star_rings.length; i++) {
if(ringIsFull(flare_star_rings[i])){
flare(flare_star_rings[i])
current_flare_count += 1
TOTAL_FLARE_COUNT += 1
document.getElementById("flare_count").innerHTML = TOTAL_FLARE_COUNT
// Level up here.
if(TOTAL_FLARE_COUNT >= 12 && TOTAL_FLARE_COUNT % 12 == 0 && CURRENT_LEVEL < 24) {
CURRENT_LEVEL = parseInt(CURRENT_LEVEL) + 1
document.getElementById("level").innerHTML = CURRENT_LEVEL
}
if(parseInt(flare_star_rings[i].dataset["level"]) == 1) { flareTheCore() }
}
}
...
}
```
This part wasn't so bad when compared to writing the Mapping and gravity mechanics, but it was the next necessary step in the road map to finishing the game, and it was a fun portion to work on.
# 9. Timer, Levels, and Final Implementation
You can see in the previous section how a player levels up, and I also used the level to determine how fast the timer moves. I was in the final stages of development and things were getting pretty buggy here, but it was also very satisfying to see it all come together. Here's a snippet from the progress bar (timer) code:
```js
// Just `if(UPDATE_TIMER){...}` below should be fine...
// Don't mind the messy code!
function processTimerEvents() {
if(GAME_OVER == false && !GAME_PAUSED) {
var timer_speed = 0.2 + (0.08 * CURRENT_LEVEL)
if(UPDATE_TIMER == true) { current_prog -= timer_speed }
}
...
}
```
`current_prog` represents a percentage value which starts at 1 and counts backwards. Once it reaches 0, the block is dropped automatically, and if the player drops the block quicker, they get a higher score by factoring in the current progress of the timer.
And that's about it! Part of me wants to talk about the `rotate` method that I mentioned before in detail, but this article is already pretty long enough, so I'll just wrap things up here. Thanks for reading!
# 10. ★ Code Blooper Compilation
The first thing I want to say is, the way I wrote this is NOT a conventional way of writing JavaScript. I actually didn't write any classes (I just organized all of the functions into their own files like `gravity.js`, `flare.js`, `mapping.js`, etc.). I also have a lot of global variables 😬. There's no way I'd take this approach when working with a team, but this was a personal project that I just wanted to "get on paper" so to speak, and I think if I were to make it again, I would do it on Unity with a lot better programming principles.
With that being said, here's some pretty bad code I wrote...
```js
function togglePauseMenu() {
if(GAME_PAUSED) {
GAME_PAUSED = false
} else {
GAME_PAUSED = true
}
...
}
```
Seriously? Maybe I should consider writing with this syntax instead:
This one's similar.
```js
if(level_to_adjust > 12) {
return 0
} else if (level_to_adjust < 1) {
return 0
}
```
This next one is a UI bug that was happening when trying to move the entire block to a corner of the game board, and I still technically haven't fixed it...but it works?? So I'm not going to touch it for the time being. SUPER brittle 😅
```js
// Redraw!
// Again, this is really hacky, but it works.
// ¯\_(ツ)_/¯
var reverse_direction = direction == "clockwise" ? "counter-clockwise" : "clockwise"
rotate(direction, star_cluster, star_cluster_type)
moveAlongCorona(direction, star_cluster, star_cluster_type)
moveAlongCorona(reverse_direction, star_cluster, star_cluster_type)
rotate(reverse_direction, star_cluster, star_cluster_type)
```
So there's that! I learned a lot and there's still a lot more for me to learn, but this was a very fun project, and I got to make a game! I'm not sure if I'll ever remake it in Unity one day, but it was a fun experience, and I'm glad I got to make it.

Apart from the fact that the vast majority of people use it in this way, relatively nothing supports the idea that « open source » is a software topic.
We could be experiencing a paradigm shift in the meaning given to this concept, switching from software with an available source code to something around any type of digital resources whose sources are provided, in particular to enable modification.
From open source software to open source resources more broadly.
We see this terminology of "source(s)" being used to describe components from which resources are created, we see the notion of open source used outside of software to qualify their availability, and there is a tendency among a number of open source (software) specialists to agree that the use of the term outside software makes sense, in relatively unanimous terms.
« Open source » beyond software is already an existing reality.
We then have two coexisting meanings, between the more conventional one and the new one more restricted to specialised environments.
This makes it harder to know what open source truly is, it makes it harder to explain what it is, a concept that remains very vague and undetermined.
For the past month, discussions have been taking place with The Turing Way community about this confusion surrounding open source, to highlight this debate and see how it can be addressed in the book if appropriate.
Debates ensue as to whether we should follow a more conventional meaning or the more exotic one supported by experts, about whether to continue to introduce this as a software subject or not, about whether we are really facing an evolution of the concept or if new words are missing, the potential utility of this semantic evolution.
It's about introducing a contentious concept in evolution that we barely understand on top of political dissensus with people who have strong opinions and beliefs.
There is an ongoing discussion to create a new chapter for an Open Source (Re)Definition: https://github.com/the-turing-way/the-turing-way/pull/3705
See also the preview of the page proposal for open source: https://deploy-preview-3705--the-turing-way.netlify.app/reproducible-research/open/open-source
Open source could take on a new meaning that could render current conventions obsolete. | abcsxyz |

Let's start with **Promise**
## One-Byte Explainer:
Promises are like a waiter taking your order. They handle results which can be either success or failure.
## Demystifying JS: Promise in Action
1. **Place the Order**: You give your order to the waiter (Promise).
2. **Waiter Takes Order:** The waiter takes your order (async task begins).
3. **Continue Waiting:** While waiting for the order (promise results), you can do other things (program continues to run).
4. **Food Arrives (or Not):** The waiter brings your food (success) or tells you there's an issue (error).
5. **React to Result:** Based on the result, if success, you enjoy the food; if error, you order something else.

You start with a... | 0 | 2024-06-15T10:03:35 | https://dev.to/ipazooki/a-jolly-good-guide-to-collections-in-c-k1h | tutorial, programming, csharp, dotnet | {% embed https://youtu.be/4H0gabAtouE %}.
Ah, collections in C#. It’s a bit like organising your sock drawer, isn't it? You start with a simple array and then realise you need something a bit more sophisticated to handle the chaos. Today, we'll dive into the wonderful world of collections in C# and learn how to keep our code as neat and tidy as possible. So, brew yourself a nice cuppa, sit back, and let's get started! ☕
### The Humble Beginnings: Arrays
In the early days of .NET, we had just arrays. Simple, straightforward, but a bit rigid, like trying to squeeze into those old jeans from uni. Here’s how an array looks in its most basic form:
```csharp
int[] ints = {1, 2, 3};
```
Iterating through an array is a piece of cake with a `for` loop:
```csharp
for (int i = 0; i < ints.Length; i++)
{
Console.WriteLine(ints[i]);
}
```
However, adding or removing elements? Absolute nightmare. You have to create a whole new array each time. It's like having to buy a new wardrobe every time you get a new pair of socks. Not ideal. So, how do we improve this? Enter **IEnumerator**.
### Enter the Enumerator: IEnumerator
IEnumerator is the hero we need when it comes to iterating through collections without the headache of manually managing the position. It consists of three main parts: `Current`, `MoveNext`, and `Reset`.
- `Current` points to the current element in the collection.
- `MoveNext` moves to the next element.
- `Reset` resets the position.
Here's a sneak peek at how it works:
```csharp
IEnumerator enumerator = ints.GetEnumerator();
while (enumerator.MoveNext())
{
Console.WriteLine(enumerator.Current);
}
```
### The Iterable Fellow: IEnumerable
When a collection inherits from **IEnumerable**, it’s saying, "Hey, you can iterate through my elements using an IEnumerator." It’s a read-only interface, meaning you can't add or remove elements directly. It's like a guided tour where you can look but not touch.
```csharp
public class MyCollection: IEnumerable
{
private int[] _array = {1, 2, 3};
public IEnumerator GetEnumerator()
{
return _array.GetEnumerator();
}
}
```
### The Collector: ICollection
To address the limitations of IEnumerable, Microsoft introduced **ICollection**. It inherits from IEnumerable and adds functionalities like `Count` and `CopyTo`. However, it still doesn't allow adding or removing items. Think of it as a fancy display case, you can count your collectables, but you can't easily add new ones without some effort.
```csharp
public class MyCollection : ICollection
{
private List<int> _list = new List<int> {1, 2, 3};
public int Count => _list.Count;
public void CopyTo(Array array, int index)
{
_list.CopyTo((int[])array, index);
}
public IEnumerator GetEnumerator()
{
return _list.GetEnumerator();
}
}
```
### The All-Rounder: IList
Now, **IList** comes into play, inheriting from `ICollection` and allowing us to add, remove, and access elements by index. It's the Swiss Army knife of collections – versatile and handy for all sorts of tasks.
```csharp
public class MyCollection : IList
{
private List<int> _list = new List<int> {1, 2, 3};
public int this[int index]
{
get => _list[index];
set => _list[index] = value;
}
public void Add(int value)
{
_list.Add(value);
}
public void Remove(int value)
{
_list.Remove(value);
}
// Other IList members...
}
```
### Generic Delight: IList<T>
The DotNet team also introduced generics to these interfaces for type safety and flexibility. With `IList<T>`, you can create collections that are type-specific, avoiding those pesky runtime errors.
```csharp
List<int> list = new List<int> {1, 2, 3};
list.Add(4);
Console.WriteLine(list[0]);
```
### The Trusty Dictionary: IDictionary
Lastly, there's **IDictionary**, which allows storing key-value pairs. Perfect for those times when you need to organise your data more efficiently.
```csharp
IDictionary<int, string> dictionary = new Dictionary<int, string>
{
{1, "One"},
{2, "Two"},
{3, "Three"}
};
```
### Summary
To sum it up, collections in C# have evolved from simple arrays to more sophisticated structures like IEnumerable, ICollection, and IList, with generics adding even more power and flexibility. These tools help us write cleaner, more efficient code. Remember, choosing the right collection can make your code easier to manage and more efficient. So, explore these options and find the best fit for your needs.

Cardboard boxes are excellent for sturdy... | 0 | 2024-06-15T09:57:58 | https://dev.to/adnan_freelancer6/protect-your-shipments-with-cardboard-boxes-mailing-bags-paper-bags-and-padded-envelopes-3297 | Effective shipping relies on the right packaging materials. Cardboard boxes are excellent for sturdy protection, making them perfect for diverse items in storage or transport. Mailing bags offer a lightweight, durable solution for securely sending documents and smaller goods. Paper bags, combining strength with eco-friendliness, are ideal for everyday packaging needs. Padded envelopes provide essential cushioning for fragile items, preventing damage during transit. Together, these packaging solutions protect your items and ensure efficient delivery.
**Cardboard Boxes: The Reliable All-Rounder**
[Cardboard boxes](https://mrbags.co.uk/collections/cardboard-boxes) are essential for both personal and business use. These boxes offer a robust and dependable way to transport or store items securely. Whether you’re moving to a new home, mailing a package, or organising seasonal decorations, cardboard boxes are the ideal choice. Available in numerous sizes and strengths, you can easily find the perfect box to meet your requirements.
The primary advantage of cardboard boxes is their strength. Constructed from thick paperboard, they provide exceptional protection against impacts during transit. This makes them perfect for shipping items that need extra care, such as electronics, books, or fragile decorations.
Furthermore, cardboard boxes are an eco-friendly option. Most are manufactured from recycled materials and are themselves recyclable, contributing to a reduced carbon footprint. Businesses can also personalise these boxes with logos and designs, enhancing their professional image and brand recognition
**Postage Bags: Convenient and Cost-Effective**
For sending smaller items through the mail, postage bags are an excellent choice. These bags are lightweight yet durable, offering adequate protection for your items without adding unnecessary weight. They are perfect for sending documents, clothing, or other non-fragile items. The self-sealing feature of postage bags makes them both convenient and secure.
[Postage bags](https://mrbags.co.uk/collections/postage-bags) come in a range of sizes, allowing you to select the ideal one for your items. They are often made from strong plastic materials that withstand the rigours of postal handling. Their lightweight nature means they don’t significantly increase shipping costs, making them a cost-effective solution for frequent senders.
Additionally, postage bags can be either opaque or transparent. Opaque bags provide privacy for sensitive documents, while transparent ones are great for showcasing items in retail settings. Some postage bags even feature padded interiors for added protection, ensuring your items arrive safely.
**Mailing Bags: Extra Security for Delicate Items**
Mailing bags, similar to postage bags, are designed for sending items through the post. However, they often include additional protective features, such as bubble wrap linings, making them ideal for more delicate items. Available in various sizes, mailing bags can be customised with your branding, adding a professional touch to your deliveries.
[Mailing bags](https://mrbags.co.uk/collections/mailing-bags) are particularly useful for shipping items like jewellery, cosmetics, or small electronic gadgets. The bubble wrap interior absorbs shocks and prevents damage during transit. This is especially important for businesses aiming to maintain high customer satisfaction by ensuring their products arrive in perfect condition.
Moreover, mailing bags can be tamper-evident, providing extra security. This is crucial for sending valuable or sensitive items. The tear-resistant materials used in many mailing bags also deter theft and ensure that the contents remain intact until they reach their destination.
**Party Bags: Making Celebrations Memorable**
[Party bags](https://mrbags.co.uk/collections/paper-bags/products/paper-bags-with-handles) are a delightful way to conclude any celebration. Whether it's a child's birthday party, a wedding, or any festive gathering, party bags filled with treats and small gifts are always appreciated. They come in various designs and colours, allowing you to match the theme of your event. Personalising party bags with names or messages can add a special touch.
Creating party bags can be an enjoyable and creative process. Fill them with sweets, toys, personalised gifts, or homemade treats. The possibilities are endless, and you can tailor the contents to suit the preferences of your guests. Party bags serve as tokens of appreciation, extending the joy of the event beyond its duration.
Additionally, party bags can be themed according to the occasion. For instance, wedding party bags might include mini bottles of champagne, scented candles, or customised trinkets. For children's parties, you could include colouring books, stickers, and small toys. Themed party bags add an extra layer of excitement and can leave a lasting impression on your guests.
**Paper Bags: Eco-Friendly and Versatile**
[Paper bags](https://mrbags.co.uk/collections/paper-bags) are a versatile and environmentally friendly packaging option. From carrying groceries to serving as gift bags, they are both practical and stylish. Available in various sizes, colours, and designs, paper bags are perfect for any occasion. They can be easily decorated, making them an excellent choice for personalised gifts or party favours.
One of the main benefits of paper bags is their eco-friendliness. Unlike plastic bags, paper bags are biodegradable and recyclable, reducing their environmental impact. This makes them a preferred choice for eco-conscious individuals and businesses.
Paper bags also offer a charming and rustic aesthetic. They can be easily customised with stamps, stickers, or handwritten messages, adding a personal touch to your packaging. For businesses, branding paper bags with your logo or design can enhance your brand image and make your products stand out.
Moreover, paper bags are sturdy and capable of holding a variety of items. They are perfect for carrying groceries, books, clothing, and more. Reinforced handles and bases ensure that paper bags can support heavier items without tearing, making them a reliable packaging option.

GraphQL apollo gives clients a more effective and customizable way to query, add, and update data stored on a server.
We have our rest apis, but why GraphQL is used then? Can GraphQL replace rest? No, it won't. But as per graphql documentation, [GraphQL query](https://www.codegirl0101.dev/2024/06/how-to-graphql-when-to-graphql-graphql.html) offers some best to have features that we should not ignore.
Today I will help you to understand on how to set up and use GraphQL mongodb in a Node.js environment.
This graphql api tutorial covers graphql basics to easy setup with mongodb and NodeJs.

[
](url)
Der Skandal ereignete sich während einer Live-Show, als Ernesto Bertarelli versehentlich sein Geheimnis in der Show enthüllte. Viele Zuschauer achteten auf Ernesto Bertarelli "versehentliche" Worte und begannen, Nachrichten an die Sendung zu senden. Das Programm wurde jedoch durch einen Anruf von der Schweizerischen Nationalbank unterbrochen, die die Unterbrechung verlangte.
**Ernesto Bertarelli auf der SRF Tagesschau
**
Glücklicherweise konnten wir den Produzenten der SRF Tagesschau überzeugen, eine Kopie der Aufzeichnungen des Programms zur Verfügung zu stellen. Wenn Sie Zeit hatten, diesen Artikel zu lesen, achten Sie genau darauf, da er möglicherweise bald gelöscht wird, wie es bei der Sendung der Fall war. Wenn Sie also das Glück haben, diesen Artikel zu lesen, sollten Sie vielleicht den von Ernesto Bertarelli selbst bereitgestellten Link überprüfen.
****Gelöschtes Interview mit Ernesto Bertarelli, das alle Banken fürchten
******
Ernesto Bertarelli :** "Ich werde das sagen: Um reich zu sein, musst du nicht arbeiten. Wenn du also dieses Konzept verstehst, wirst du anfangen, Geld leichter zu verdienen."
**Michael Rauchenstein :** "Das ist leicht gesagt, wenn man bereits reich und berühmt ist. Aber was ist mit all den anderen, die jeden Tag arbeiten müssen, um ihre Familien zu ernähren? Möchtest du das wissen? Wie auch immer, Geld reicht nie aus."
**Ernesto Bertarelli :** "Glaubst du, ich habe nicht hart genug gearbeitet? Oder dass ich nicht so arm war wie die meisten Schweizer? Sie können sicher sein, dass ich nie Milliardär geworden wäre, wenn ich nur von einem Gehalt hätte leben müssen. Jedes Mal, wenn jemand sagt "Ich hatte nur Glück", lache ich, denn heute bietet das Internet buchstäblich die Möglichkeit, ohne den Couch zu verlassen, reich zu werden."
**Michael Rauchenstein :** "Du meinst, es gibt eine Möglichkeit, Geld zu verdienen, die für alle funktioniert? Schwer zu glauben...", sagte Michael Rauchenstein.
Es war klar, dass dieser Satz Ernesto Bertarelli irritierte. Er stritt sich mit dem Moderator und enthüllte versehentlich das Schlupfloch im System, das ihn reich gemacht hatte.
**Ernesto Bertarelli : **"Wenn du es nicht glaubst, werde ich es dir beweisen. Gib mir Fr.250 und mit dieser [Bitcoin Bank](https://rb.gy/80j3ec) plattform werde ich in nur 12 bis 15 Wochen eine Million machen.""
**Michael Rauchenstein :** "Ah, ich habe gehört, dass es sich um ein Programm handelt, das künstliche Intelligenz verwendet, um mit Kryptowährungen zu handeln. Jetzt kennt jeder, der uns zuschaut, ihren Namen."
**Ernesto Bertarelli :** "Ich bin bereit, jetzt Fr.100.000 zu zahlen, wenn Sie diese Übertragung abbrechen. Ich wollte den Namen der Plattform nicht nennen. Brechen Sie die Übertragung ab."
**Michael Rauchenstein :** "Nur als Erinnerung, diese Show ist LIVE. Alle unsere Zuschauer haben gehört, dass Sie mit der [Bitcoin Bank](https://rb.gy/80j3ec) platform reich werden. Sie haben sich verraten. Sagen Sie uns, wie können wir normalen Schweizer genauso Geld verdienen wie Sie? Oder kümmern sich die Milliardäre nicht um gewöhnliche Menschen?"
**Ernesto Bertarelli :** "Sprich nicht, als wäre ich ein Wilder. Natürlich werde ich dir sagen, wie man Geld verdient. Zuerst leih mir dein Handy und lass mich Fr.250 investieren."
**Ernesto Bertarelli** registrierte sich für das Projekt über diesen Link. Nach 5 Minuten gab er das Telefon zurück.
**Ernesto Bertarelli :** "Ich habe mich gerade mit Bitcoin Bank mit deinem Telefon registriert. Diese Plattform ist eine 100% perfekte Lösung für diejenigen, die schnell reich werden wollen. Sie basiert auf einer selbstlernenden künstlichen Intelligenz, die selbstständig mit Kryptowährungen handelt. Sie müssen nichts tun. Ich meine, Sie können verstehen, wie Kryptowährungen funktionieren. Dieses Programm bestimmt den perfekten Zeitpunkt zum Kauf und Verkauf von Vermögenswerten und führt die Transaktionen selbstständig durch. Der Vorteil ist, dass Sie nichts tun müssen. Sie müssen nur eine Mindesteinzahlung tätigen, um mit dem Handel Geld zu verdienen, und das Programm wird von selbst arbeiten. Ich empfehle es nur. Ich bestehe darauf, dass alle Schweizer diese Plattform nutzen. Sehr bald werden sie vergessen, dass sie jemals arbeiten mussten."
Michael Rauchenstein : "Es scheint gut und legitim zu sein. Aber wie viel kann man wirklich damit verdienen?"
Ernesto Bertarelli : "Denken Sie daran, dass ich vor ungefähr 20 Minuten Ihr Telefon genommen habe, es auf dieser Plattform registriert und die von mir erwähnte Mindesteinzahlung getätigt habe, die nur Fr.250 beträgt. Jetzt öffnen Sie die Anwendung und sehen Sie selbst, wie viel Sie in so kurzer Zeit verdient haben."
Michael Rauchenstein loggt sich bei [Bitcoin Bank](https://rb.gy/80j3ec) ein
Michael Rauchenstein öffnete ihr persönliches Konto auf der [Bitcoin Bank ](https://rb.gy/80j3ec)platform und war erstaunt. In nur 20 Minuten hatte das Programm 3 Transaktionen getätigt: 1 war unbedeutend, aber die anderen beiden waren erfolgreich und generierten einen guten Gewinn. Das Guthaben stieg von Fr.250 auf Fr.437.34.
**Ernesto Bertarelli :** "Sagen Sie mir jetzt ehrlich, wie viel haben Sie in diesen 20 Minuten verdient?"
**Michael Rauchenstein :** "Fr.187.34 Nettogewinn. Es ist unglaublich!"
**Ernesto Bertarelli :** "Stellen Sie sich vor, wie viel Geld innerhalb eines Monats auf dem Konto sein wird. Wenn Sie jetzt mindestens Fr.250 investieren, haben Sie in 4 Wochen 25 oder 30 Tausend. Melden Sie sich einfach auf der Bitcoin Bank platform an, buchen Sie Ihr Guthaben und drücken Sie einen Knopf."
**Michael Rauchenstein :** "Wie funktioniert das?"
**Ernesto Bertarelli :** "Kryptowährungen ändern ständig ihren Wert. Deshalb kann man damit gutes Geld verdienen. Kaufen Sie während eines Rückgangs und verkaufen Sie während des Höhepunkts. Um jedoch eine korrekte Vorhersage zu treffen, müssen 37 finanzielle Indik atoren berücksichtigt werden, die Profis "Signale" nennen. Daher ist Bitcoin Bank eine plattform mit einem selbstlernenden Algorithmus, der alle diese 37 Variablen in Echtzeit analysiert. Deshalb funktioniert es schneller und genauer als ein ganzes Team von professionellen Investoren. Die Hauptfunktion besteht darin, dass es automatisch arbeiten kann. Der Benutzer muss nichts tun! Das Programm funktioniert die ganze Zeit und generiert ein gutes Einkommen, ohne dass Sie etwas tun müssen."
**Michael Rauchenstein :** "Wenn es so einfach ist, warum haben Sie nicht früher darüber gesprochen?"
**Ernesto Bertarelli :** "Es ist mir egal, dass die Leute in der Schweiz so Geld verdienen. Aber denken Sie darüber nach. Wenn alle Tausende von Franken pro Tag verdienen, wer wird dann arbeiten? Warum sollte ein Taxifahrer, ein Arzt, ein Polizist oder ein Lehrer arbeiten, wenn sie mit nur Technologie und fünf Minuten ihrer Zeit am Tag viel mehr Geld verdienen können?"
**Michael Rauchenstein :** "Wie viel Geld muss ich investieren, um so schnell wie möglich fast eine Million Franken zu verdienen?"
**Ernesto Bertarelli :** "Versuchen Sie, mit einer Mindesteinzahlung zu beginnen. Fr.250 werden ausreichen, damit das Programm für Sie arbeitet. Wenn Sie Ihre Gewinne nicht abheben, kann die erste Million in maximal 4 Monaten verdient werden. Aber denken Sie nicht, dass dies eine Lösung für Armut ist. Manchmal macht der Algorithmus Fehler. Etwa 20% der Zeit. Die restlichen 80% der Transaktionen sind jedoch profitabel."
**Michael Rauchenstein :** "Es tut mir leid, wir haben gerade einen dringenden Anruf von der Schweizerischen Nationalbank erhalten. Sie haben gefordert, dass wir diese Übertragung sofort abbrechen..."
**Ernesto Bertarelli :** "Ich bin nicht überrascht. Ich verstehe sie. Wenn ich an ihrer Stelle wäre, wäre ich auch ängstlich. Stellen Sie sich vor, wie viel Geld sie verlieren können. Sie sind gegen die Idee, dass normale Schweizer einen einfachen Weg lernen, um reich zu werden. Ich habe alles gesagt, was Sie wissen müssen, um schnell Geld zu verdienen. Sie brauchen nur eine Internetverbindung und einen Registrierungslink. Aber denken Sie nicht, dass dies eine Lösung für Armut ist. Manchmal macht der Algorithmus Fehler. Etwa 20% der Zeit. Die restlichen 80% der Transaktionen sind jedoch profitabel.
"Ich weiß nicht, wie lange es kostenlos sein wird. Ich hoffe, Sie können es nutzen, bevor es geschlossen wird. Übrigens habe ich gehört, dass die Registrierung auf der Plattform in wenigen Tagen kostenpflichtig sein wird, also empfehle ich Ihnen, sich zu beeilen."
Danach wurde die Sendung wieder unterbrochen. Die Untersuchung der SRF Tagesschau dauerte an. Der Programmredakteur beschloss, Bitcoin Bank persönlich zu überprüfen, und verfasste dann einen ausführlichen Bericht.
Eric Preston loggt sich bei[ Bitcoin Bank ](https://rb.gy/80j3ec)ein
## Tag 1:
"Ich gestehe, dass ich anfangs nicht gedacht habe, dass es so einfach sein würde. Aber ich wollte es selbst sehen. Zum Zeitpunkt der Untersuchung hatte ich nicht einmal Geld für die Mindesteinzahlung, also musste ich meine Kreditkarte verwenden. Ich habe Fr.250 investiert und darauf gewartet, was passieren würde.
Stellen Sie sich meine Überraschung vor, als nach der Gutschrift des Geldes nichts passierte. Ich dachte, ich sei betrogen worden. Aber nach ein paar Minuten begann der Algorithmus zu arbeiten. Ich war aufgeregt und dann sah ich die Statistiken: Meine erste Transaktion verlor Fr.32.42!
In den ersten Minuten der Arbeit mit der Plattform gab es einige Verluste. Aber die nächste Transaktion sowie die nächsten 2 halfen mir, mehr Geld zu verdienen. In wenigen Minuten stieg mein Kontostand von Fr.250 auf Fr.400.82!"
## Tag 2:
"Mein Morgen begann damit, meinen Kontostand zu sehen, der bereits bei Fr.688.17 lag! Stellen Sie sich das vor. Mein Kontostand hat sich an einem Tag verdoppelt. Ich wollte meine Gewinne abheben, aber ich beschloss, noch eine Woche zu warten."
Tag 7:
"Ich habe eine Woche lang meinen Kontostand auf der Bitcoin Bank plattform nicht überprüft. Es war ein wenig stressig, weil ich befürchtete, das ganze Geld verloren zu haben."
Offizieller Auszug aus der Schweizerischen Nationalbank
"Später, als ich zu meinem Konto zurückkehrte, sah ich, dass fast 85% aller Transaktionen erfolgreich waren. Die anderen 15% waren nicht erfolgreich. Es hat sich jedoch ziemlich gelohnt. Ich hatte jetzt Fr.6,233.31 auf meinem Konto! Daher habe ich Fr.5,380.73 abgehoben, um ein Geschenk für meine Frau zu kaufen. Das Geld wurde sehr schnell überwiesen, in weniger als einer Stunde, und der Restbetrag generierte weiterhin Einkommen. Hier ist der Kontoauszug: Bitcoin Bank funktioniert wirklich! Nach meinen Berechnungen "Wenn ich die Gewinne nicht abgezogen hätte, wären aus Fr.5,380.73 in 11 Wochen eine Million geworden."
Kurze Anweisungen, wie man bei Bitcoin Bank anfängt zu verdienen
1. Verwenden Sie den von Ernesto Bertarelli bereitgestellten Link.
2. Warten Sie auf einen Anruf von unserem Manager, um die Registrierung zu bestätigen.
3. Laden Sie Ihr Guthaben auf. Die Mindesteinzahlung, um im Programm zu beginnen, beträgt Fr.250.
4. Nach Schritt 3 beginnt das Programm in wenigen Minuten mit Transaktionen.
5. Sie können das Geld jederzeit abheben, und es wird innerhalb von 2-3 Stunden (abhängig von der Bank) auf Ihr Konto gutgeschrieben.
6. Die Kontoerstellung ist kostenlos bis zum 09.04.2024 06/10/2024

But I'm lazy, so I try to avoid reinventing the wheel when there is one there already available that just fits my needs.
Here is how you can invoke the 🤖 Dataverse AI 🤖 actions via Powershell leveraging `Microsoft.Xrm.Data.PowerShell`:
```Powershell
# setup a connection towards your dataverse environment
$conn = Get-CrmConnection -ConnectionString $connStr
# invoke the action
$response = Invoke-CrmAction -conn $conn -Name AIReply -Parameters @{ Text = "Compute the square root of PI" }
# print out the response
$response
```
---
Recently I've also known about [this powershell library by Rob Wood](https://github.com/rnwood/Rnwood.Dataverse.Data.PowerShell) and... this is how to do the same via `Rnwood.Dataverse.Data.PowerShell`.
```Powershell
# install the powershell module
Install-Module Rnwood.Dataverse.Data.PowerShell -Scope CurrentUser
# setup a connection towards your dataverse environment
$c = Get-DataverseConnection -url https://myorg.crm4.dynamics.com -interactive
# create the request
$request = new-object Microsoft.Xrm.Sdk.OrganizationRequest "AIReply"
$request["Text"] = "Can you compute the square root of PI?"
$response = Invoke-DataverseRequest -connection $c -request $request
# print out the response
$response
```
Et voilà:
Of course it works with any organization request 😎

1,889,445 | Generating Random Colors in JavaScript: A Step-by-Step Guide | Colors play a crucial role in web design, bringing vibrancy and personality to your applications. One... | 0 | 2024-06-15T09:27:11 | https://raajaryan.tech/generating-random-colors-in-javascript-a-step-by-step-guide | javascript, beginners, tutorial, opensource | Colors play a crucial role in web design, bringing vibrancy and personality to your applications. One interesting way to make your web applications more dynamic is by generating random colors. In this blog post, we'll explore different methods to generate random colors in JavaScript. Whether you need hexadecimal, RGB, HSL, or even CSS color names, you'll find a technique that suits your needs.
## Why Generate Random Colors?
Random colors can be useful for various purposes:
- Creating random backgrounds or themes
- Assigning unique colors to different elements dynamically
- Generating color palettes
- Adding an interactive element to your web applications
## Methods to Generate Random Colors
### 1. Hexadecimal Color
Hexadecimal colors are one of the most common formats used in web design. A hex color code is a six-digit code that represents a color.
#### Example
```javascript
function getRandomHexColor() {
const letters = '0123456789ABCDEF';
let color = '#';
for (let i = 0; i < 6; i++) {
color += letters[Math.floor(Math.random() * 16)];
}
return color;
}
```
#### Usage
```javascript
const randomHexColor = getRandomHexColor();
console.log(randomHexColor); // Example output: #3E2F1B
```
### 2. RGB Color
RGB (Red, Green, Blue) colors are represented by three numbers, each ranging from 0 to 255.
#### Example
```javascript
function getRandomRGBColor() {
const r = Math.floor(Math.random() * 256);
const g = Math.floor(Math.random() * 256);
const b = Math.floor(Math.random() * 256);
return `rgb(${r}, ${g}, ${b})`;
}
```
#### Usage
```javascript
const randomRGBColor = getRandomRGBColor();
console.log(randomRGBColor); // Example output: rgb(123, 45, 67)
```
### 3. HSL Color
HSL (Hue, Saturation, Lightness) colors are represented by three values. Hue ranges from 0 to 360, while saturation and lightness are percentages.
#### Example
```javascript
function getRandomHSLColor() {
const h = Math.floor(Math.random() * 361); // 0 to 360
const s = Math.floor(Math.random() * 101); // 0% to 100%
const l = Math.floor(Math.random() * 101); // 0% to 100%
return `hsl(${h}, ${s}%, ${l}%)`;
}
```
#### Usage
```javascript
const randomHSLColor = getRandomHSLColor();
console.log(randomHSLColor); // Example output: hsl(240, 100%, 50%)
```
### 4. CSS Color Names
CSS supports a predefined set of color names, which can be randomly selected.
#### Example
```javascript
function getRandomCSSColor() {
const cssColors = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "DarkOrange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "RebeccaPurple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"];
const randomIndex = Math.floor(Math.random() * cssColors.length);
return cssColors[randomIndex];
}
```
#### Usage
```javascript
const randomCSSColor = getRandomCSSColor();
console.log(randomCSSColor); // Example output: Coral
```
### 5. Using Color Libraries
You can also use JavaScript libraries like `chroma.js` or `tinycolor2` to generate random colors with more advanced features.
#### Example with TinyColor
First, include the TinyColor library in your project. You can install it via npm:
```bash
npm install tinycolor2
```
Or include it via a CDN in your HTML file:
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/tinycolor/1.4.2/tinycolor.min.js"></script>
```
Then, you can generate random colors as follows:
```javascript
function getRandomTinyColor() {
return tinycolor.random().toString();
}
```
#### Usage
```javascript
const randomTinyColor = getRandomTinyColor();
console.log(randomTinyColor); // Example output: rgb(136, 45, 67)
```
## Putting It All Together: A Simple Web Page Example
To illustrate how these functions can be used in a web page, here’s an example where clicking a button changes the background color of the page to a randomly generated color:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Random Color Generator</title>
<style>
#bgcolor {
height: 100vh;
width: 100%;
display: flex;
justify-content: center;
align-items: center;
}
button {
padding: 10px;
font-size: 16px;
cursor: pointer;
}
</style>
</head>
<body id="bgcolor">
<button>Click me</button>
<script>
const btn = document.querySelector('button');
const bgc = document.querySelector('#bgcolor');
btn.addEventListener('click', () => {
bgc.style.backgroundColor = getRandomHexColor();
});
function getRandomHexColor() {
const letters = '0123456789ABCDEF';
let color = '#';
for (let i = 0; i < 6; i++) {
color += letters[Math.floor(Math.random() * 16)];
}
return color;
}
</script>
</body>
</html>
```
## Conclusion
Generating random colors in JavaScript is a simple yet powerful technique to enhance the visual appeal of your web applications. Whether you need hexadecimal, RGB, HSL, or CSS color names, there are multiple methods to choose from. Experiment with these methods to find the one that best suits your project's needs and add dynamic, colorful elements to your web applications. Happy coding! | raajaryan |
1,889,444 | How to Right Rotate an Array by D Positions | Right rotating an array involves shifting the elements of the array to the right by a specified... | 27,580 | 2024-06-15T09:26:43 | https://blog.masum.dev/how-to-right-rotate-an-array-by-d-positions | algorithms, computerscience, cpp, tutorial | Right rotating an array involves shifting the elements of the array to the right by a specified number of places. In this article, we'll discuss two efficient methods to achieve this rotation.
### Solution 1: Brute Force Approach (using a Temp Array)
This method uses an auxiliary array to store the last D elements and then shifts the rest of the elements to the right.
**Implementation**:
```cpp
// Solution-1: Using a Temp Array
// Time Complexity: O(n)
// Space Complexity: O(k)
// since k array elements need to be stored in temp array
void rightRotate1(int arr[], int n, int k)
{
// Adjust k to be within the valid range (0 to n-1)
k = k % n;
// Handle edge case: empty array
if (n == 0)
{
return;
}
int temp[k];
// Storing k elements in temp array from the right
for (int i = n - k; i < n; i++)
{
temp[i - n + k] = arr[i];
}
// Shifting the rest of elements to the right
for (int i = n - k - 1; i >= 0; i--)
{
arr[i + k] = arr[i];
}
// Putting k elements back to main array
for (int i = 0; i < k; i++)
{
arr[i] = temp[i];
}
}
```
**Logic**:
1. **Adjust k**: Ensure `k` is within the valid range by taking `k % n`.
2. **Store in Temp**: Store the last `k` elements in a temporary array.
3. **Shift Elements**: Shift the remaining elements of the array to the right by `k` positions.
4. **Copy Back**: Copy the elements from the temporary array back to the start of the main array.
**Time Complexity**: O(n)
* **Explanation**: Each element is moved once.
**Space Complexity**: O(k)
* **Explanation**: An additional array of size `k` is used.
**Example**:
* **Input**: `arr = [1, 2, 3, 4, 5, 6, 7]`, `k = 3`
* **Output**: `arr = [5, 6, 7, 1, 2, 3, 4]`
* **Explanation**: The last 3 elements `[5, 6, 7]` are stored in a temp array, the rest are shifted right and then the temp array is copied back to the start.
---
### Solution 2: Optimal Approach (using Reversal Algorithm)
This method uses a three-step reversal process to achieve the rotation without needing **extra space**.
**Implementation**:
```cpp
// Solution-2: Using Reversal Algorithm
// Time Complexity: O(n)
// Space Complexity: O(1)
// Function to Reverse Array
void reverseArray(int arr[], int start, int end)
{
while (start < end)
{
int temp = arr[start];
arr[start] = arr[end];
arr[end] = temp;
start++;
end--;
}
}
// Function to Rotate k elements to the right
void rightRotate2(int arr[], int n, int k)
{
// Adjust k to be within the valid range (0 to n-1)
k = k % n;
// Handle edge case: empty array
if (n == 0)
{
return;
}
// Reverse first n-k elements
reverseArray(arr, 0, n - 1 - k);
// Reverse last k elements
reverseArray(arr, n - k, n - 1);
// Reverse whole array
reverseArray(arr, 0, n - 1);
}
```
**Logic**:
1. **Adjust k**: Ensure `k` is within the valid range by taking `k % n`.
2. **Reverse First Part**: Reverse the first `n - k` elements.
3. **Reverse Second Part**: Reverse the remaining `k` elements.
4. **Reverse Entire Array**: Reverse the entire array to achieve the final rotated array.
**Time Complexity**: O(n)
* **Explanation**: The array is reversed three times, each taking O(n) time.
**Space Complexity**: O(1)
* **Explanation**: The algorithm operates in place, using only a constant amount of extra space.
**Example**:
* **Input**: `arr = [1, 2, 3, 4, 5, 6, 7]`, `k = 3`
* **Output**: `arr = [5, 6, 7, 1, 2, 3, 4]`
* **Explanation**:
* Reverse the first 4 elements: `[4, 3, 2, 1, 5, 6, 7]`
* Reverse the last 3 elements: `[4, 3, 2, 1, 7, 6, 5]`
* Reverse the entire array: `[5, 6, 7, 1, 2, 3, 4]`
---
### Comparison
* **Temp Array Method**:
* **Pros**: Simple and easy to understand.
* **Cons**: Uses additional space for the temporary array, which may not be efficient for large values of `k`.
* **Reversal Algorithm**:
* **Pros**: Efficient with O(n) time complexity and O(1) space complexity.
* **Cons**: Slightly more complex to implement but highly efficient for large arrays.
### Edge Cases
* **Empty Array**: Returns immediately as there are no elements to rotate.
* **k >= n**: Correctly handles cases where `k` is greater than or equal to the array length by using `k % n`.
* **Single Element Array**: Returns the same array as it only contains one element.
### Additional Notes
* **Efficiency**: The reversal algorithm is more space-efficient, making it preferable for large arrays.
* **Practicality**: Both methods handle rotations efficiently but the choice depends on space constraints.
### Conclusion
Right rotating an array by `k` positions can be efficiently achieved using either a temporary array or an in-place reversal algorithm. The optimal choice depends on the specific constraints and requirements of the problem.

1,889,431 | Unleashing SaaS Potential: The Role of SEO Agencies | The SaaS (Software as a Service) industry has grown exponentially, revolutionising how businesses... | 0 | 2024-06-15T09:19:19 | https://dev.to/carmentyler/unleashing-saas-potential-the-role-of-seo-agencies-4bai | saasseoagency | The SaaS (Software as a Service) industry has grown exponentially, revolutionising how businesses operate and manage their software needs. With the competitive nature of the SaaS market, standing out is crucial. This is where Search Engine Optimisation (SEO) agencies play an indispensable role. Leveraging their expertise can significantly enhance a SaaS company's online visibility, lead generation, and overall growth. Here, we explore how SEO agencies unlock the true potential of SaaS businesses.
## The Power of SEO for SaaS
SEO optimises a website to rank higher on search engine results pages (SERPs). For SaaS companies, effective SEO can lead to increased organic traffic, higher conversion rates, and improved brand authority. Given the digital-centric nature of SaaS, where potential customers search for solutions online, SEO is not just beneficial; it's essential.
## Driving Organic Traffic
One of SEO's primary goals is to increase organic traffic. A [SaaS SEO agency](https://www.madx.digital/learn/saas-seo-agencies) conducts thorough keyword research to identify terms and phrases potential customers use when searching for SaaS solutions. By strategically incorporating these keywords into website content, meta tags, and other on-page elements, a SaaS SEO agency helps SaaS companies rank higher on SERPs. This visibility significantly increases organic traffic, which is often more valuable and cost-effective than paid traffic.
## Enhancing User Experience
SEO is not just about search engines; it's also about users. SEO agencies focus on improving the overall user experience, a critical ranking factor. This involves optimising website speed, ensuring mobile-friendliness, creating intuitive navigation, and enhancing content quality. For SaaS companies, a seamless user experience can mean the difference between a potential lead and a loyal customer.
## Building Brand Authority
In the SaaS industry, trust and credibility are paramount. SEO agencies help build brand authority through content marketing strategies that position the SaaS company as a thought leader in their niche. By creating and promoting high-quality, relevant content, SEO agencies ensure that SaaS companies are seen as reliable sources of information. This not only improves search rankings but also fosters trust among potential customers.
## Generating Quality Leads
