Reserved characters in HTML must be replaced with entities:
< (less than) = <
> (greather than) = >
## **HTML Character Entities**
Some characters are reserved in HTML.
If you use the less than (<) or greater than (>) signs in your HTML text, the browser might mix them with tags.
Entity names look like this:
&entity_name;
Entity numbers look like this:
&#entity_number;
To display a less than sign (<) we must write: < or <
Entity names are easier to remember than entity numbers.
## **Non-breaking Space**
A commonly used HTML entity is the non-breaking space:
A non-breaking space is a space that will not break into a new line.
Two words separated by a non-breaking space will stick together (not break into a new line). This is handy when breaking the words might be disruptive.
## **Examples**
§ 10
10 km/h
10 PM
## **Combining Diacritical Marks**
A diacritical mark is a "glyph" added to a letter.
Some diacritical marks, like grave ( ̀) and acute ( ́) are called accents.
## **HTML Symbols**
Symbols or letters that are not present on your keyboard can be added to HTML using entities.
## **HTML Symbol Entities**
Many mathematical, technical, and currency symbols, are not present on a normal keyboard.
## **Example**
Display the euro sign:
```HTML
<p>I will display €</p>
<p>I will display €</p>
<p>I will display €</p>
The HTML charset Attribute
```
The character set is specified in the `<meta>` tag:
## **Example**
```HTML
<meta charset="UTF-8">
```
## **The ASCII Character Set**
ASCII was the first character encoding standard for the web. It defined 128 different characters that could be used on the internet:
English letters (A-Z)
Numbers (0-9)
Special characters like ! $ + - ( ) @ < >.
The ANSI Character Set
ANSI was the original Windows character set:
Identical to ASCII for the first 127 characters
Special characters from 128 to 159
Identical to UTF-8 from 160 to 255
```HTML
<meta charset="Windows-1252">
```
## **The ISO-8859-1 Character Set**
ISO-8859-1 was the default character set for HTML 4. This character set supported 256 different character codes. HTML 4 also supported UTF-8.
Identical to ASCII for the first 127 characters
Does not use the characters from 128 to 159
Identical to ANSI and UTF-8 from 160 to 255
## **Example**
```HTML
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1">
```
## **The UTF-8 Character Set**
is identical to ASCII for the values from 0 to 127
Does not use the characters from 128 to 159
Identical to ANSI and 8859-1 from 160 to 255
Continues from the value 256 to 10 000 characters
## **Example:**
```HTML
<meta charset="UTF-8">
```

## Explainer
A hash function takes a key or input data and maps it to a fixed-size, uniformely distributed value (hash), later used for data retrieval. It strives to be fast, only generate one possible hash per input and make key mapping possible in near constant time.
## Additional Context
Hashes are hard to define because it has many similar concepts in the field, which are used almost interchangibly; it is especially hard not to confuse them with _checksums_ - those are interested in data integrity, not mapping. Also, results uniformely distributed is an essential property to make use of the hash value constant in time, since no hash is more probable than another from the same function.
Another important distinction is to separate general hash functions to cryptographic ones: the latter takes computational effort to make a 1 to 1 mapping to input (any one input can only be represented by one hash) and to make the original input unguessable by the hash alone, among other differences. | fmalk |

Some years ago, I was listening to an old interview with Agostinho da Silva, a Portuguese philosopher who died 30 years ago, and he said something that has been in my mind ever since: "The Man is not born to work, the Man is born to create".
This goes contrary to the current belief in developed countries, which says that the life of a Man must be dedicated to his work for most of his years.
Who wouldn't like to spend more time on himself and his hobbies instead of working? However, in the current days, with the age of retirement increasing and the pension system more and more fragile, it seems that one is doomed to spend his time working to maintain his quality of life.
In this post, I'll explain how I plan to be able to retire at 35, and how to have a plan for your financial life.
----
## Why should I be worried about my retirement?
<figcaption>Source: <a href="https://giphy.com/gifs/relax-florida-hammock-7Je6xJ0kPxUORZSvv8" target="_blank">Giphy</figcaption></br>
With the increase in the retirement age and a growing elderly population in most developed countries, the pension system of most developed countries is under big pressure. With the planned decrease of the real value of pensions in most countries, it seems certain that if someone wants to keep their quality of life after retirement, they must save money by their means. Besides, a retirement plan also allows you to plan an early retirement, or at least to reach financial independence.
An early retirement means you can retire before retirement age and live off the return of your investments, doing minimal work. It means to focus on what you want, without being tied to a job. It means to do whatever you want without money holding you back. Do you want to spend a year traveling? You can do it. Do you want to spend a year doing a course? Do you want to learn an instrument? Or spend more time with your family? You can have time to do all that once you are financially independent.
If you like your job and want to keep working, that's also not a problem. Just because you've reached financial independence, it does not mean that you must stop working.
----
## Setting your goal
<figcaption>Photo by <a href="https://flic.kr/p/f71k" target="_blank">Martin Cathrae</a> on Flickr</figcaption></br>
To reach financial independence, the first step is to define your goal. It is different for everyone, and everyone has a different number. But a rule of thumb is that you can retire when you have invested 25x the value of your annual expenses. This value assumes that your investments return on average 4% by year, a rather conservative return rate. For example, if you spend 10.000€ each year, you can retire when you have invested 250.000€ and live off of the investment returns.
The 4% return is based on some assumptions. For example, you'll live approximately 30 years past your retirement date, you have a portfolio of 50% stock and 50% bonds, and you are not including taxes or investment fees. For a more in-depth discussion about it, check out this [Vanguard analysis](https://corporate.vanguard.com/content/dam/corp/research/pdf/Fuel-for-the-F.I.R.E.-Updating-the-4-rule-for-early-retirees-US-ISGFIRE_062021_Online.pdf) or this [updated study](https://thepoorswiss.com/updated-trinity-study/). We will stick to 4% for the rest of the discussion, however it may vary slightly depending on your investment profile.
After defining your goal, you must define the steps to achieve it.

## Where to invest
<figcaption style="text-align: center">Source: <a href="https://giphy.com/gifs/showtime-ray-donovan-jon-voight-mickey-xTiTniXrZvZBrDIZri" target="_blank">Giphy</a></figcaption></br>
You want your investment to have some characteristics:
- It must have an equal to or higher return than the market. You don't want to invest most of your money in a savings account or on most of the capital-guaranteed products.
- You want your investment to have low fees, to avoid the return of your investment being mostly used to cover the investment fees.
- You want your investment to be diversified so that you don't have to worry about losing all your money because a single company or market is down; in this way, you are reducing volatility.
- You want your investments to be simple to understand so you can do it easily and consistently.
In the FIRE (Financial Independence, Retire Early) community, one of the most popular strategies for investing in the long-term is Passive ETFs. ETFs (Exchange-Traded Funds) are funds structured to track a group of securities - a group of stocks, for example. When an ETF tracks different markets, with many companies of different industries, diversification is achieved. Being passive means that no portfolio manager makes the decisions on when to buy and when to sell. It usually means lower fees than active funds.
In some studies, it's also shown that most simple investment strategies yield better results than complex ones. In 2007, Warren Buffet bet a million dollars that over a decade, a simple S&P500 Index Fund (a fund that tracks the biggest 500 companies in the USA market) would outperform a basket of hand-picked active managed funds. Ten years later, the S&P500 index would gain 125.8%, while the other five chosen funds had gains of 21.7%, 42.3%, 87.7%, 2.8% and 27.0%.
A passive strategy usually has better results because of the lower fees. Besides, most funds, even though they are managed by highly skilled analysts, do not beat the market. If they do not beat the market, the odds are that you will also not beat the market. So instead of choosing individual stocks to beat the market, FIRE long-term investors focus on investing in the market, which is what ETFs track, at low cost.
Some of the most popular ETFs are ETFs that track the S&P500 index (eg. SPY, VUAA, SXR8), ETFs that track the world economy (eg. VWCE, IUSQ), ETFs that track developed markets (eg. IWDA, SWRD, VGVF), or ETFs that track emerging markets (EMIM, IEMA, VFEA).

## Focus on the savings rate
<figcaption style="text-align: center">Source: <a href="https://giphy.com/gifs/rodneydangerfield-thinking-math-rodney-gEvab1ilmJjA82FaSV" target="_blank">Giphy</a></figcaption></br>
After knowing where to invest, it's time to optimize your life for your investments. The savings rate is the percentage of money you can save every month from your income. It's probably the most important number to focus on. You want it to be as high as possible so that you can invest as much as possible from your income.
As a rule of thumb, you can know when you will reach your financial independence number by looking at your savings rate:
{% katex %}
x = 50 * (1 - savings rate)^{1.5}
{% endkatex %}
where x is the number of years that will take you to reach your financial independence number (assuming it's 4% of your annual expenses).
If you have a savings rate of 40%, it will take 23 years to reach financial independence. However, if your savings rate is 60%, it will take just 12 years. It's important to invest as much and as early as possible because, as investment interest compounds, it can make a big difference in a few years.
To increase the savings rate, there are two things you can do:
- **Increase income** - this does not come as a surprise, but increasing income is probably the best way to increase the savings rate. Unlike reducing expenses, there is no upper limit to how much we can increase our income. Reevaluate your job situation and the market. Can you increase your income by switching jobs? Can you ask for a raise from your boss?
- **Reduce expenses** - reducing expenses is not about depriving yourself and living a depressing life, but instead focusing on what is important and reducing the superfluous waste. You want to make conscious choices to live efficiently, knowing that you are investing for a better future. This often includes renegotiation of energy/water/gas contracts, canceling unnecessary subscriptions, and avoiding unnecessary spending.

## Changing your mindset
<figcaption style="text-align: center">Source: <a href="https://giphy.com/gifs/theminimalists-minimalism-simplicity-the-minimalists-rFDMmUYI9P3GCVtalR" target="_blank">Giphy</a></figcaption></br>
When reducing expenses, we are confronted with some crossroads and difficult decisions. Should we sell our car and use public transportation? Should we reduce our vacation spending and focus on cheaper alternatives? Should we move to a smaller house to save on the rent? Those are very personal decisions and there is no one-size-fits-all solution. What you need to understand is that you define your priorities. You can calculate how much you will save by selling your car or moving to a smaller house, and then calculate how much time that decision will save you in reaching financial independence.
The key to reducing your expenses consistently is to find a balance between your present and future well-being. Discover your priorities and use the money accordingly. Such a mindset is called **valuist - someone who discovers what they intrinsically value, and creates more of that**. For a valuist, the money to upgrade your car or move into a larger house, can be invested and grow over time, and it can have much more value a few years from now. A valuist will only spend that money if he believes that the use of the money now will be better than in a few years (that can be multiplied by 2 or 3).
As someone who focuses on experiences, a valuist mindset is similar to a minimalist or a frugalist. A **minimalist mindset focuses on finding freedom by owning only what adds value to someone's life**, and doing that, focusing on experiences and making more deliberate decisions. A **frugalist mindset focuses on paying less for what you need**.
As you can see, these three mindsets complement each other and make it easier to live a happy and fulfilling life while keeping your expenses low and helping you reach financial independence.

## There are still many misconceptions about the idea of retiring early
<figcaption style="text-align: center">Source: <a href="https://giphy.com/gifs/netflix-spike-lee-shes-gotta-have-it-sghi-ZaJtnTY8tFZz0PvmW9" target="_blank">Giphy</a></figcaption>
- **"I don't invest because I don't have time to always be looking for the stock prices"**
If you are investing in the long-term, probably you shouldn't be always watching the stock prices, because you are not focused on short-term results. When you invest in the long-term, the returns can take some time.
In 2014, a study was conducted by Fidelity on its client accounts. The study tried to identify the best investors by reviewing account returns. They discovered that the best investors were already dead or had forgotten to log on to their accounts for a long time. This only shows that most of the time, the best you can do to your investment is to do nothing.
Reevaluate your investments every 3 or 6 months, but remind yourself that the biggest mistake every investor makes is to sell the investments too early.
- **"I need to learn a lot before I start investing"**
If you follow a simple investment plan, like I suggested above, the knowledge you need to start investing is minimal. There is no need to know how to analyze a balance sheet or an annual report. Many people overrate the need to learn everything about investing, but like many other things, investing is mostly learned on the go. If you wait to learn everything before investing, chances are you will never do it. If you feel you lack some knowledge, you can spend some time learning, but do it within a defined time-frame, 3 months or so. When that time-frame has passed, you know it's time to start investing. Time is a crucial part of investing, and studies show that you should start as early as possible, so don't waste time (and money) and start as soon as possible.
- **"I am going to lose all my money if I start investing"**
A lot of people are afraid of losing all their money if they start investing. That's understandable, given the stories they heard from their parents and friends. However, investing does not need to be so risky. In reality, when following a diversified strategy as suggested above and focusing on the long-term, history suggests that it's uncommon to lose money at all when the years go by. Even more, the probability of higher returns only increases with time. So time is your best ally.
Moreover, most passive ETFs are capitalization-weighted, which means that the weight of every company is determined by its market value. If a company goes bankrupt or its stock crashes, its impact on the ETF is reduced because its weight in the ETF decreases over time. On the other hand, if another company is growing, its weight in the ETF will increase over time. By investing in a capitalization-weighted ETF, you are protecting yourself from the impact that a single company can have on your portfolio.
- **"If I stop working, I don't know what to do and I will get depressed"**
This is a real problem for many of the people that retire early. From an early age, we were trained to live to work. This mindset is deeply in our minds, so much so that we connect our identity with our work - what we do is what we are, it's our purpose. When you retire, you lose your purpose, which can have a very negative impact on your identity and your mental health. Many early retirees feel anxious or depressed months after their retirement date. Some studies even relate an early retirement to a decline in health.
While stopping work can be a big change for someone who from their early years always had their days occupied, there are some techniques that you can try to get used to this new chapter of life.
- Before you fully commit to early retirement, try to imagine how your life will be. How will you fill your days? What will be your day-to-day routine?
- Have some hobbies that you like to spend time doing. Maybe you like to practice sports, gardening, or volunteering. This can be a great way to keep yourself active and happy with your life while having a healthier lifestyle.
- Create a bucket list of things to do. What did you always want to do that you never have the time? Learn a new language? Learn a new musical instrument? Travel the world? Now it's the time to do it!
Yes, life after early retirement can be a challenge, at least in the beginning. It's an adaptation to a whole new life pace, where you get to call all the shots on your next step. However, if planned correctly, it can also be a second life where you have the time and the knowledge to be who you want to be, without any financial burden holding you back.

## Will I actually retire early?
I'm planning so that I can reach financial independence as soon as possible. I'm currently 25% through it, and by my estimates, I plan to reach it when I'm 35.
I don't know yet if I will want to retire early. However, I would like to have the option. Reaching financial independence is a superpower that allows you to have bigger freedom, to live on your own terms, and to have an extra piece of mind.

No cotidiano, costumamos apenas realizar ações simples como pull, commit, merge e push.
No entanto, o git é uma ferramenta complexa, a sua incorreta utilização pode resultar em danos como perdas de código nos quais você ainda não tivesse "commitado" no seu repositório, se isso aconteceu com você, provavelmente você ficou muito preocupado que todo o tempo investido naquele código tivesse sido jogado fora.
Se você utiliza o VScode que é um dos editores de texto mais populares entre programadores, eu fico muito feliz de te dizer que você não perdeu o seu código, nesse artigo vou te mostrar como utilizar o [Visual Studio Code](https://code.visualstudio.com) para recuperar o seu código perdido no Git.
A funcionalidade que vamos utilizar se chama "Local History", foi adicionada na versão [1.66 do VsCode em Março de 2022](https://code.visualstudio.com/updates/v1_66#_local-history).
Se você prefere o aprendizado de forma visual, você pode assistir o vídeo abaixo que foi publicado no canal do **Código ao Ponto** no Youtube.
{% youtube xTo9turfbF0 %}
## A solução
Para resolver esse problema realize os seguintes passos:
1. Digitar <kbd>f1</kbd> para abrir a paleta de comandos do Vscode
2. Pesquisar pela funcionalidade: “Local History: Find Entry to Restore”
3. Após selecionar, você deverá procurar e selecionar o nome do arquivo que você perdeu, o VsCode irá te mostrar todas as versões do seu arquivo que ele tem salvo e os horários de alterações no seu arquivo.
4. Após encontrar, basta clicar e o seu código será restaurado para a versão selecionada.
### Conclusão
O Vscode é um editor de texto sensacional, possui tantas funções e atalhos que é impossível saber tudo que essa ferramenta pode te entregar. Fiquei muito surpreso ao descobrir que o VsCode guarda o histórico de alterações dos arquivos que foram editados nele, mas que bom que ele faz isso, porque vai ajudar muito quando aquelas alterações que fizemos e não "commitamos" foram acidentalmente desfeitas.

Hi!
Today I’ll try to expand a little the scenario described in this Semantic Kernel blog post: “[Azure OpenAI On Your Data with Semantic Kernel](https://devblogs.microsoft.com/semantic-kernel/azure-openai-on-your-data-with-semantic-kernel?WT.mc_id=academic-00000-brunocapuano)“.
The code below uses an GPT-4o model to support the chat and also is connected to Azure AI Search using SK. While runing this demo, you will notice the mentions to [doc1], [doc2] and more. Extending the original SK blog post, this sample shows at the bottom the details of each one of the mentioned documents.
A similar question using Azure AI Studio, will also shows the references to source documents.
## Semantic Kernel Blog Post
The SK team explored how to leverage Azure OpenAI Service in conjunction with the Semantic Kernel to enhance AI solutions. By combining these tools, you can harness the capabilities of large language models to work effectively with data, using Azure AI Search capabilities. The post covered the integration process, highlighted the benefits, and provided a high-level overview of the architecture.
The post showcases the importance of context-aware responses and how the Semantic Kernel can manage state and memory to deliver more accurate and relevant results. This integration between SK and Azure AI Search empowers developers to build applications that **_understand and respond to user queries in a more human-like manner_**.
The blog post provides a code sample showcasing the integration steps. To run the scenario, you’ll need:
- Upload our data files to Azure Blob storage.
- Vectorize and index data in Azure AI Search.
- Connect Azure OpenAI service with Azure AI Search.
For more in-depth guidance, be sure to check out the full post [here](https://devblogs.microsoft.com/semantic-kernel/azure-openai-on-your-data-with-semantic-kernel/).
## Code Sample
And now it’s time to who how we can access the details of the response from a SK call, when the response includes information from Azure AI Search.
Let’s take a look at the following program.cs to understand its structure and functionality.
- The sample program is a showcase of how to utilize Azure OpenAI and Semantic Kernel to create a chat application capable of generating suggestions based on user queries.
- The program starts by importing necessary namespaces, ensuring access to Azure OpenAI, configuration management, and Semantic Kernel functionalities.
- Next, the program uses a configuration builder to securely load Azure OpenAI keys from user secrets.
- The core of the program lies in setting up a chat completion service with Semantic Kernel. This service is configured to use Azure OpenAI for generating chat responses, utilizing the previously loaded API keys and endpoints.
- To handle the conversation, the program creates a sample chat history. This history includes both system and user messages, forming the basis for the chat completion service to generate responses.
- An Azure Search extension is configured to enrich the chat responses with relevant information. This extension uses an Azure Search index to pull in data, enhancing the chat service’s ability to provide informative and contextually relevant responses.
- Finally, the program runs the chat prompt, using the chat history and the Azure Search extension configuration to generate a response.
- This response is then printed to the console. Additionally, if the response includes citations from the Azure Search extension, these are also processed and printed, showcasing the integration’s ability to provide detailed and informative answers.

TL; DR: How to deploy docker to minikube when one does not need anything fancy, but pure Raku.
---
So, you have your own pet K8s cluster deployed as minikube and you want to play with it. You have few microservices to build and you don't want to bother with kubernetes low level commands at all.
On the other hand, you setup is _complex enough_ to express it in a bunch of yaml files or kubectl commands. Here is an elegant way to handle this in pure Raku, and it's called Sparky ...
---
# Show me the design
```
|-------------------------------------|
| Sparky -> kubectl -> MiniKube |
| /\ /\ /\ |
| pod pod pod |
|-------------------------------------|
```
So the infrastructure part is simple - on the same host we install minikube and Sparky that underlying uses kubectl to deploy containers into k8s cluster.
# Show me the code
As usually Sparky job is a pure Raku code, but this time some plugins will be of use as well ...
Sparky is integrated with - Sparrowhub - https://sparrowhub.io - repository of Sparrow plugins - useful building blocks for any sort of automation.
Let's use a couple of them - k8s-deployment and k8s-pod-check to deploy and check Kubernetes pods. From Sparky point of view those are *just Raku functions*, with some input parameters.
```perl
task-run "dpl create", "k8s-deployment", %(
:deployment_name<nginx>,
:app_name<nginx>,
:image<nginx:1.14.2>,
:3replicas,
);
# give it some time to allow all pods to start ...
sleep(5);
task-run "nginx pod check", "k8s-pod-check", %(
:name<nginx>,
:namespace<default>,
:die-on-check-fail,
:3num,
);
```
For the tutorial purpose we are going to deploy nginx server with 3 replicas, by using [k8s-deployment](https://sparrowhub.io/plugin/k8s-deployment/0.000004) plugin.
Let's give it a try.
# First run
And the very first deploy ... fails:
```
... some output ...
11:03:34 :: deployment.apps/nginx created
11:03:34 :: [repository] - installing k8s-pod-check, version 0.000012
11:03:34 :: [repository] - install Data::Dump to /home/astra/.sparrowdo/minikube/sparrow6/plugins/k8s-pod-check/raku-lib
All candidates are currently installed
No reason to proceed. Use --force-install to continue anyway
[task run: task.pl6 - nginx pod check]
[task stdout]
11:03:41 :: ${:die-on-check-fail(Bool::True), :name("nginx"), :namespace("default"), :num(3)}
11:03:41 :: ===========================
11:03:41 :: NAME READY STATUS RESTARTS AGE
11:03:41 :: nginx-77d8468669-5gxbf 0/1 ErrImagePull 0 5s
11:03:41 :: nginx-77d8468669-c5vbl 0/1 ErrImagePull 0 5s
11:03:41 :: nginx-77d8468669-lhc54 0/1 ErrImagePull 0 5s
11:03:41 :: ===========================
11:03:41 :: nginx-77d8468669-5gxbf POD_NOT_OK
11:03:41 :: nginx-77d8468669-c5vbl POD_NOT_OK
11:03:41 :: nginx-77d8468669-lhc54 POD_NOT_OK
[task check]
stdout match <^^ 'nginx' \S+ \s+ POD_OK $$> False
---
```
Although Kubernetes deployment has been successfully created, further [k8s-pod-check](https://sparrowhub.io/plugin/k8s-pod-check/0.000012) failed to verify that all pods are running.
Use of `die-on-check-fail` option made the job stops strait away after this point.
The reason is in `ErrImagePull` - nginx docker image is not accessible from within a minikube, which a known minkube DNS issue, which is easy to fix.
# It's fixed!
All we need to do is to upload nginx docker image _manually_, so that minukube will pick it up from a file cache:
```bash
minikube image load nginx:1.14.2
```
Now, when have restarted the failed job we get this:
```
... some output ...
11:05:42 :: deployment.apps/nginx unchanged
[task run: task.pl6 - nginx pod check]
[task stdout]
11:05:47 :: ${:die-on-check-fail(Bool::False), :name("nginx"), :namespace("default"), :num(3)}
11:05:47 :: ===========================
11:05:47 :: NAME READY STATUS RESTARTS AGE
11:05:47 :: nginx-77d8468669-5gxbf 1/1 Running 0 2m10s
11:05:47 :: nginx-77d8468669-c5vbl 1/1 Running 0 2m10s
11:05:47 :: nginx-77d8468669-lhc54 1/1 Running 0 2m10s
11:05:47 :: ===========================
11:05:47 :: nginx-77d8468669-5gxbf POD_OK
11:05:47 :: nginx-77d8468669-c5vbl POD_OK
11:05:47 :: nginx-77d8468669-lhc54 POD_OK
[task check]
stdout match <^^ 'nginx' \S+ \s+ POD_OK $$> True
<3 pods are running> True
---
```
The last deployment has not changed (with is denoted by "deployment.apps/nginx unchanged" line), as we did not change anything, however minikube now is able to pick the recently uploaded docker image and all pods now are running.
Congratulation with the very first successfully deployment to Kubernetes via Sparky!
# Clean up
In the end let's remove our test pods, by using k8s-deployment plugin:
```perl
task-run "dpl delete", "k8s-deployment", %(
:deployment_name<nginx>,
:action<delete>,
);
```
# Further thoughts
This simple scenario is going to give us some ideas on how to deploy to Kubernetes in imperative way using pure Raku, I, personally like this approach better, as having a bunch of helm charts and yaml files seems overkill when one need just to deploy some none production code, however, as always YMMV, thanks for reading ... | melezhik |
1,888,614 | JDBC nedir ? | JDBC (Java Database Connectivity), Java programlama dili ile yazılmış uygulamaların ilişkisel... | 0 | 2024-06-14T13:55:21 | https://dev.to/mustafacam/jdbc-nedir--1fk1 | JDBC (Java Database Connectivity), Java programlama dili ile yazılmış uygulamaların ilişkisel veritabanları ile etkileşimde bulunmasını sağlayan bir API'dir. JDBC, Java uygulamaları ile veritabanları arasında bir köprü görevi görerek SQL sorgularını çalıştırmayı, veritabanı bağlantılarını yönetmeyi ve sonuçları işlemeyi mümkün kılar. JDBC, Java Standard Edition (Java SE) platformunun bir parçasıdır.
### JDBC'nin Temel Bileşenleri
1. **JDBC Sürücü (Driver)**: JDBC sürücüsü, Java uygulaması ile belirli bir veritabanı arasında iletişimi sağlayan yazılımdır. Farklı veritabanları için farklı JDBC sürücüleri bulunmaktadır (örneğin, MySQL, PostgreSQL, Oracle, vb. için farklı sürücüler).
2. **Connection**: Veritabanı ile bağlantıyı temsil eder. Bağlantı oluşturmak için gerekli bilgiler (URL, kullanıcı adı, parola) kullanılır.
3. **Statement**: SQL sorgularını çalıştırmak için kullanılır. `Statement`, `PreparedStatement` ve `CallableStatement` olmak üzere üç ana türü vardır:
- **Statement**: Basit SQL sorguları için kullanılır.
- **PreparedStatement**: Parametreli SQL sorguları için kullanılır. SQL enjeksiyon saldırılarına karşı daha güvenlidir.
- **CallableStatement**: Saklı prosedürleri çalıştırmak için kullanılır.
4. **ResultSet**: SQL sorgularının sonuçlarını temsil eder. Veritabanından dönen veri kümesi bu nesne ile işlenir.
### JDBC Kullanarak Veritabanı İşlemleri
Aşağıda, JDBC kullanarak bir veritabanına bağlanma, veri ekleme, veri sorgulama ve bağlantıyı kapatma işlemlerinin nasıl yapıldığını gösteren bir örnek bulunmaktadır.
#### Gerekli Importlar
```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
```
#### JDBC Kullanarak Veritabanına Bağlanma ve Veri İşleme
```java
public class JDBCDemo {
// Veritabanı bağlantı bilgileri
static final String DB_URL = "jdbc:mysql://localhost:3306/your_database_name";
static final String USER = "your_username";
static final String PASS = "your_password";
public static void main(String[] args) {
Connection conn = null;
Statement stmt = null;
try {
// JDBC sürücüsünü yükle
Class.forName("com.mysql.cj.jdbc.Driver");
// Veritabanına bağlan
System.out.println("Veritabanına bağlanılıyor...");
conn = DriverManager.getConnection(DB_URL, USER, PASS);
// Statement oluştur
stmt = conn.createStatement();
// Veri ekleme (INSERT) örneği
String sql = "INSERT INTO Employees (name, age, department) VALUES ('John Doe', 30, 'HR')";
stmt.executeUpdate(sql);
System.out.println("Veri eklendi...");
// Veri sorgulama (SELECT) örneği
sql = "SELECT id, name, age, department FROM Employees";
ResultSet rs = stmt.executeQuery(sql);
// Sonuçları işleme
while (rs.next()) {
int id = rs.getInt("id");
String name = rs.getString("name");
int age = rs.getInt("age");
String department = rs.getString("department");
// Veriyi ekrana yazdır
System.out.println("ID: " + id + ", Name: " + name + ", Age: " + age + ", Department: " + department);
}
// ResultSet'i kapat
rs.close();
} catch (SQLException se) {
// JDBC hatalarını işle
se.printStackTrace();
} catch (Exception e) {
// Genel hataları işle
e.printStackTrace();
} finally {
// Kaynakları kapat
try {
if (stmt != null) stmt.close();
} catch (SQLException se2) {
}
try {
if (conn != null) conn.close();
} catch (SQLException se) {
se.printStackTrace();
}
}
System.out.println("İşlem tamamlandı...");
}
}
```
### JDBC Adımları
1. **Sürücüyü Yükle**: `Class.forName("com.mysql.cj.jdbc.Driver");`
2. **Bağlantıyı Oluştur**: `conn = DriverManager.getConnection(DB_URL, USER, PASS);`
3. **Statement Oluştur**: `stmt = conn.createStatement();`
4. **SQL Sorgusu Çalıştır**: `stmt.executeUpdate(sql);` veya `stmt.executeQuery(sql);`
5. **Sonuçları İşle**: `ResultSet rs = stmt.executeQuery(sql);`
6. **Kaynakları Kapat**: `rs.close();`, `stmt.close();`, `conn.close();`
Bu temel adımlarla JDBC kullanarak bir veritabanına bağlanabilir, veri ekleyebilir, sorgu çalıştırabilir ve sonuçları işleyebilirsiniz. | mustafacam | |

Code refactoring is the process of restructuring existing computer code without changing its external behavior or functionality. It is a crucial step in software development that helps improve code quality, maintainability, and readability. In this blog, we will delve into the technical aspects of code refactoring, exploring the techniques, best practices, and challenges involved in this process.
### Techniques and Best Practices
There are several techniques and best practices for refactoring code, including:
1. **Correcting Composing Methods**: This involves streamlining code by removing duplication and making future changes easier. This can be achieved by identifying and eliminating duplicate code, and by breaking down complex methods into smaller, more manageable pieces.
2. **Simplifying Conditional Expressions**: This involves improving code readability by simplifying complex conditions. This can be achieved by breaking down complex conditions into simpler ones, and by using more readable and maintainable conditional statements.
3. **Moving Features Between Objects**: This involves redistributing functionality among classes to improve maintainability. This can be achieved by identifying and moving features that are not tightly coupled to a specific class, and by ensuring that the moved features are properly integrated into the new class.
4. **Organizing Data**: This involves improving data handling and class associations to make classes more recyclable and portable. This can be achieved by identifying and organizing data in a more structured and maintainable way, and by ensuring that data is properly encapsulated and accessed.
5. **Improving Generalization**: This involves enhancing code by making it more reusable and adaptable. This can be achieved by identifying and generalizing common patterns and behaviors, and by ensuring that the generalized code is properly tested and validated.
### When to Refactor
Refactoring can be done at various stages of software development, including:
1. **Preventive Refactoring**: This involves refactoring code before it becomes complex to prevent technical debt. This can be achieved by identifying and addressing potential issues early on, and by ensuring that code is properly designed and implemented from the start.
2. **Corrective Refactoring**: This involves refactoring code to correct existing issues and improve maintainability. This can be achieved by identifying and addressing existing issues, and by ensuring that code is properly tested and validated.
3. **Refactoring During Code Review**: This involves refactoring code during peer review to ensure it is clean and maintainable. This can be achieved by identifying and addressing potential issues during code review, and by ensuring that code is properly tested and validated.
4. **Refactoring During Regularly Scheduled Intervals**: This involves refactoring code as part of regular maintenance to keep it clean and efficient. This can be achieved by identifying and addressing potential issues during regular maintenance, and by ensuring that code is properly tested and validated.
### Challenges and Motivation
Refactoring can be challenging due to the need to understand the existing codebase and the potential for introducing new bugs. However, refactoring is motivated by the desire to improve code quality, reduce technical debt, and make software development more predictable and efficient.
### Conclusion
Code refactoring is a crucial step in software development that helps improve code quality, maintainability, and readability. By understanding the techniques and best practices for refactoring, developers can ensure that their code is clean, efficient, and easy to maintain.

Solve error “Failed to listen on 127.0.0.1:8000 (reason: ?)” when run “php artisan serve”
**Resolution**
Access your php.ini file in your PHP version folder. If you like me are using Laravel Herd on Windows you can access using the route "%USERPROFILE%\.config\herd\bin".
Now in your php.ini change the "variables_order" value.
```
// before
variables_order = "EGPCS"
// after
variables_order = "GPCS"
```
**Alternative**
If this don't work you can also start the server with PHP start command.
```
php -S localhost:8000 -t public
```
That's it. I hope it will help you. | williammeier |

All further numbers below are based on the number of AppExchange apps available at the marketplace in May 2024. We’ve gathered all apps (yes, it took a while) from the official website, including information about their primary categories and the company developer behind them. Since the Salesforce marketplace has new apps published and removed daily, the statistics below may not be precisely accurate at the date of your reading. The stats we provide are for informational purposes and give the feeling of shares (not absolute numbers) inside categories.
Also, AppExchange presents industry-specific applications and solutions, even if they don’t have a business need defined in the marketplace. We included those in our research as well – you may see such apps under the “Industry” category in further breakdowns.
## Total Number of Salesforce Apps by Categories
### Share of Apps by Business Need
The AppExchange Salesforce marketplace offers a diverse range of applications categorized to meet various business needs.
_Number of Salesforce Apps by Business Needs and Industry-specific apps_
These categories help users quickly find the tools they need to enhance specific areas of their business operations. To illustrate these numbers better, please see the infographics below:
The AppExchange Salesforce marketplace categorizes applications to help users find tools for specific business needs. Each category has several more specific subcategories and app developers may select up to 3 categories/subcategories, which will be applied to their app.

## Salesforce Apps Stats by Key Appexchange Developers
From Salesforce apps by categories, we move to the companies, which stand behind these apps. There are quite interesting and insightful stats in terms of the number of apps by Appexchange developers – 5141 Salesforce apps were developed by 3122 different companies.
### **Top 15 Developers by Number of Apps**
Sales and Productivity remain the most popular categories among app developers and these top developers released 14.7% of all apps presented at the marketplace.
## Breakdowns by AppExchange App Ratings and Reviews
Here’s how the apps are distributed across different review count ranges, with the total number of all reviews being a fantastic 75,161 reviews:
- **0 reviews** : 2,457 apps
- **1-9 reviews** : 1,710 apps
- **10-49 reviews** : 701 apps
- **50-99 reviews** : 136 apps
- **100-499 reviews** : 118 apps
- **500-999 reviews** : 14 apps
- **1000+ reviews** : 5 apps
There are only 5 Salesforce apps, which have over 1k reviews, and those are:
(https://appexchange.salesforce.com/appxListingDetail?listingId=a0N300000024XvyEAE) | Screen Magic Mobile Media | 4.82 | 1021 |
_Top 5 Salesforce Apps with more than 1k reviews_
As AppExchange continues to grow as a marketplace, we anticipate that next year there would be already 10 apps with the total number of reviews above 1000, since user reviews remain to be one of the most critical decision factors, especially if several solutions with the same function are available.
### Insight:
Appexchange is indeed a marketplace since the Top 5 apps by reviews were developed by independent companies, not listed by Salesforce itself.
### **App Breakdown by Star Ratings**
Among 5141 apps we’ve analyzed, 2457 (47.79%) apps didn’t have any reviews at the time of writing.
The remaining 2684 reviewed Salesforce apps were distributed by ratings in the following way (we’ve rounded the average rating displayed on Appexchange):
_Breakdown of Apps by Star Reviews_
73.25% of apps with an average 5-star review rating actually show positive sentiment across the Salesforce community and overall positive experience with official Salesforce apps.
If we take apps with at least 5 reviews published, a breakdown would look in the following way:
_Breakdown of Star Reviews for Apps with 5 or More Reviews_
Distribution didn’t change much, which means ratings have a proportional distribution.

> Note: A copilot is an AI-powered application where users can ask questions in natural language and get responses specific to their context. The context could be the details in their dashboard, the code in the editor, etc.
Almost every technology company wants to integrate AI into their products.
As a result, it’s become essential to understand the workflow of how these applications are built and what common technologies power them.
Thus, in this article, we’ll build an AI-powered Spreadsheet copilot with user-interactive capabilities.
Here’s the tool stack we shall use:
We will build the UI of our spreadsheet chatbot application using Next.js, a React framework.
We will use WingLang for cloud capabilities.
We will use LangChain to interact with LLM providers.
Let’s begin!
---
## Application Workflow with LangChain + Winglang
The above diagram provides a high-level overview of the application workflow:
- The user will enter a prompt in the chatbot interface, something like:
1. Add a row for Sara, whose age is 29, who works in sales.
2. Add a row for Arya, whose age is 25, who works in marketing.
- The prompt will be sent as an input to the LLM models through LangChain to an LLM provider, say, OpenAI’s GPT-3.5 or GPT-4, where it will perform function calling.
- The model will provide a JSON response, which will be displayed on the app’s frontend to the user.
- Moreover, the response object from LLM will also be stored in a cloud bucket with Wing so that we are not tied to a single cloud provider and can migrate to any one of them whenever needed.
Done!
---
## LangChain Integration Walkthrough
Now, let’s look at the implementation where we integrate LangChain runnables and chains as REST API functionalities.
To get started, import the remote runnable from long-chain/runnable/remote.
Next, we define the `remoteChainToAction` function shown below, which allows us to deploy our LLM chains built with LangChain as REST APIs on the server side and invoked as remote runnables on the client side.
Here’s a breakdown of the above code:
- The function accepts a LangChain chain object as a parameter.
- It creates a runnable with the chain URL and handler function, as shown in line 5.
- At line 13, it infers and sets parameters if they are not provided.
Next, from lines 14–28 (shown below), it converts the chain object into a backend action object that will call the LangChain service with the provided input.
Almost done!
Finally, we use Winglang to store the output received from the LLM in a bucket, as demonstrated below:
For starters, Winglang is an open-source programming language that abstracts away the differences between cloud providers by defining a standard infrastructural API.
In other words, Winglang provides an API that’s common to all providers.
For instance, when defining a data storage bucket in Winglang, there’s nothing like “S3 Bucket” or “Blob storage” or “Google Cloud Storage” we specifically tailor the application code to.
Instead, there’s a common abstraction called “Bucket,” and we implement the application code specific to this “Bucket” class. This can then be compiled and deployed to any cloud provider.
The same abstraction is available for all cloud-specific entities like functions, queues, compute units, etc.
After developing the app in Winglang, the entire application code and the infrastructure we defined can be compiled to any cloud provider in a one-line command, and Winglang takes care of all backend procedures.
This way, one can just focus on the application logic and how their app interacts with the infrastructural resources rather than the specificities of a cloud platform.
And we are done with the high-level implementation details.
To recap, we converted a LangChain chain object into an action object that our backend can use to integrate a remote LangChain process, which in turn invoked a remote service to process input data and return the result. Finally, we stored the response from the LLM into a cloud Bucket defined in Winglang.
---
## Spreadsheet Copilot Demo
In this section, let’s do a demo of the AI copilot.
Here’s our spreadsheet chatbot, built using the Next.js framework, where we can perform multiple operations by entering prompts in the chat, such as adding a row, deleting a row, multiplying values, or adding a month to a date, similar to Excel.
Let’s enter this prompt: “_Add a row for Sara, whose age is 29, who works in sales._”
We get the desired result within a few seconds.
Next, let’s enter this prompt: “_Delete the row with Sara’s information._”
As depicted above, the row with Sara’s information has been deleted.
That’s it!
This is how we can build our AI-powered applications on top of LLMs with the above underlying architecture.
---
## Conclusion
With that, we come to the end of this article, where we learned how to build AI copilots powered by Winglang and LangChain.
To recap:
- We built the UI of our spreadsheet chatbot application using Next.js, a React framework.
- We used WingLang for cloud capabilities.
- We used LangChain to interact with LLM providers.
…And all of this with just a few lines of code.
Stay tuned for more insights and developments in AI and cloud computing.

PM2 monitor the application and restart it automatically while if app is crashing.
First install PM2 package
`$ npm install pm2@latest -g
# or
$ yarn global add pm2`
When managing multiple applications with PM2, use a JS configuration file to organize them.
To generate a sample configuration file you can type this command:
`pm2 init simple`
This will generate a sample ecosystem.config.js:
`module.exports = {
apps : [{
name : "app1",
script : "./app.js"
}]
}`
Now the command to add NodeJs project in pm2 list with npm script are following way
`pm2 start npm --name "{project_name}" -- run {script_name}`
For Example ,let's i have a project with name HelloWorld and script to run the project are npm run dev the following command will be.
`pm2 start npm --name "rStoreFront Backend" -- run dev`

By automating the regression tests that helps in checking the stability of the application, plenty of time can be saved and overall efficiency, accuracy and speed in the testing process can be improved. TestNG is one such powerful testing framework that helps to write and execute automated tests.
In this step by step guide, we will walk you through the TestNG framework and also the process of installing TestNG in Eclipse, which is one of the most popular Integrated Development Environment(IDE) for Java.
What is TestNG?
TestNG, also known as the “Next Generation Testing Framework,” is an open source testing framework that is designed for testing Java applications. It is a powerful framework with enhanced features that helps to simplify writing automated tests and improve the overall test automation experience.
Cedric Beust, the creator of TestNG, got inspired by [JUnit ](https://www.pcloudy.com/blogs/testng-vs-junit-testing-framework-which-one-is-better/)and NUnit testing frameworks and created TestNG in 2004. TestNG can be used to write the tests at all levels such as [Unit Testing](https://www.pcloudy.com/blogs/best-unit-testing-frameworks-to-automate-your-desktop-web-testing-using-selenium/), Integration Testing, Component Testing, Functional and [End to End automated testing](https://www.pcloudy.com/blogs/a-practical-guide-to-automating-end-to-end-api-testing/). It provides a comprehensive solution for writing and executing automated tests.
Features of TestNG
The following are some of the rich features of TestNG that makes it a distinguished framework.
Test Configuration
TestNG provides annotations that help in configuring the Pre-Test and Post-Test conditions. Annotations like @BeforeSuite, @BeforeTest, @BeforeMethod, etc, can be used to configure the Pre-Test conditions. Similarly, @AfterSuite, @AfterTest, @AfterMethod, etc. can be used for setting the Post-Test conditions. This helps in easily setting up the environment, initializing the resources and performing clean up operations.
Test Data Management
TestNG allows [Data-Driven testing](https://www.pcloudy.com/blogs/implementing-data-driven-testing-in-selenium/). It provides annotations like @DataProvider using which multiple sets of input data can be supplied in a single test. Test Scenarios with different inputs like Negative, Positive, passing random data can all be tested easily.
Parallel Test Execution
TestNG provides the feature to perform [Parallel Testing](https://www.pcloudy.com/parallel-testing/). This helps in reducing the overall [test execution](https://www.pcloudy.com/automation-execution/) time by running the tests concurrently.
Managing Test Dependencies and Groups
TestNG also offers to define the dependencies between tests. For example, in the case of an e-commerce application, the feature says that only a registered user should be allowed to login into the application. So, in the case of end to end automated tests the login test is dependent on the registration test. If the registration test fails, the login test should be skipped. Grouping the tests on the basis of common attributes is allowed by TestNG. It can help in managing complex test scenarios.
Test Assertions
[Assertions ](https://www.pcloudy.com/blogs/guide-to-testng-assertions-in-selenium-based-test-automation/)are basically verification methods that check that the expected results match with actual results. TestNG provides assertion methods that can help test the application easily. Methods like assertEquals(), assertTrue(), assertFalse(), etc. can be used to check the test results.
By now, you might have got a good grasp about What TestNG is, by learning about its features. Let’s now move towards the next section and learn about installing TestNG in Eclipse IDE.
How to Install TestNG in Eclipse
Before we move towards the installation process, let’s learn about the prerequisites first.
Prerequisites
Eclipse IDE should be installed.
Installing TestNG in Eclipse
There are two ways to install TestNG in Eclipse.
Using the Eclipse MarketPlace
Using the Install New Software menu.
Installing TestNG using the Eclipse MarketPlace

1,839,668 | Remote Startup Chaos: Do This and Thrive | Hi Coder, After the pandemic, we learned that people can be productive and efficient while working... | 0 | 2024-06-14T13:35:34 | https://dev.to/opensourceyllen/remote-startup-chaos-do-this-and-thrive-23j3 | workfromhome, remotework, startup, success | Hi Coder,
After the pandemic, we learned that people can be productive and efficient while working from the comfort of their homes. However, this flexibility comes with its own set of challenges and potential stress, especially when working remotely for a startup. That's why I decided to write this article: to help you succeed at work even when things seem a bit chaotic.
In a remote environment, it is easy to forget to respond to a question asked on Slack or to put off tasks for a few days that later become urgent. While this can happen in on-site jobs too, a colleague can show up at your desk to work on the task together. This is not the case in a remote team, where problems that aren't tackled or don't have a specific plan of attack can quickly be forgotten.
This is one of the many issues that remote teams experience and I want to share with you my journey at a startup and how I've been able to thrive (or at least survive).
#Bias for Action
In startups, formal processes are often minimal, and employees frequently juggle multiple responsibilities. For instance, you might find yourself interviewing a candidate while simultaneously working on a product feature. Or, you could be fixing a bug while collaborating with other developers on designing scalable infrastructure. This environment naturally comes with a bit of chaos, especially considering that you and your coworkers might be working remotely across different time zones and asynchronously.
Although this might seem like a recipe for disaster, you can thrive by staying organized and embracing a **bias for action**. When you identify an opportunity for improvement, take the initiative to address it and then communicate your actions to your team and manager. They will appreciate your proactive approach, your commitment to the company's success, and your efforts to drive improvements. Focus on understanding problems and devising creative solutions, rather than merely presenting issues to the team. By doing so, you help bridge the gap between challenges and solutions within your company.
Let me share with you one of my first achievements at work a month after I was hired.
#Document What You Are Doing
When encountering difficult challenges at work, make sure to document them thoroughly. Write down step-by-step instructions on how you solved the issue and create videos for yourself and your team detailing how you overcame the problem. While some challenges might be unique, having a knowledge base can be invaluable if they recur.
You can use different tools like Loom videos, Google Docs, spreadsheets, or any other medium to document your processes or solutions. The specific tool isn't as important as ensuring the information is recorded somewhere accessible. This documentation will be a valuable resource for new team members, equipping them with the information they need to succeed and freeing you from the need to remember every detail or solution to past problems. Building and maintaining processes is essential in startups, benefiting the entire company, yourself, and future team members.
With the rise of AI, you and your team members will have different learning options from the documentation you've created. For instance, one of your videos can be transcribed, and the highlights can be shared with a customer so that they understand their problem and how to solve it on their own. Some people dislike reading long documentation, but a video transcript can be of great aid. AI is great when used to help you and your team learn from each other and work more efficiently.
Here's a screenshot of the internal documentation I am working on
#Over-communicate
Communication is the key to thriving in a remote team. Communicate with your team about what you need to succeed, with your manager about roadblocks (especially during your 1:1s), and with your customers about the issues they are experiencing and how you plan to solve them. Being able to express your thoughts, ideas, and frustrations is essential. Everyone needs to know what you are doing so they can help you overcome roadblocks. They can only help you if they are aware of the challenges you are facing.
Here's an example of overcommunication
#Stay Up-to-Date with Your Tech Stack
Setting time every day or every few days to learn something new can sound like an impossible task. I bet you are busy with household chores, gym sessions, piano lessons, etc., but staying up-to-date in the tech industry is crucial. Try to set aside one hour, if possible, before your shift each day to learn something. Your company values the fact that you want to learn and is willing to invest in your growth so that you can become more efficient and bring new ideas to the team. This is not only beneficial for your company but also for your personal achievements and goals. Try to learn something, even if it's small, and you'll see how rewarding it will be in your current and future roles.
Perhaps you can take an [AWS course](https://www.pluralsight.com/browse?q=AWS&_ga=2.48635297.668274509.1718370921-437269911.1718370917), start working on some of the [FreeCodeCamp](https://www.freecodecamp.org/learn) courses, or sign up for a [Coursera](https://www.coursera.org/) degree. The platform is not as important as gaining a hard or soft skill that can potentially help you advance in your career. Ask your manager if they have any courses they pay for employees; many companies offer this.
#Conclusion
If this is your first job at a startup and things are going well for you, congratulations! You've managed to thrive in environments where many would struggle, and you should pat yourself on the back.

1,888,604 | Hardening Your Multistage Builds: Security Considerations from Base Image to Final Artifact | Multistage builds are a powerful tool in Docker, allowing developers to create efficient and... | 0 | 2024-06-14T13:35:15 | https://dev.to/platform_engineers/hardening-your-multistage-builds-security-considerations-from-base-image-to-final-artifact-ihf | Multistage builds are a powerful tool in Docker, allowing developers to create efficient and optimized Docker images by breaking the build process into multiple stages. However, this complexity also introduces potential security risks if not properly managed. In this article, we will delve into the security considerations for multistage builds, from the base image to the final artifact, and provide practical guidance on how to harden your builds.
### Base Image Selection
The base image is the foundation of your Docker image, and its security is crucial. When selecting a base image, consider the following factors:
- **Official Images**: Use official images from Docker Hub or other trusted sources. These images are regularly updated and maintained, ensuring you have the latest security patches.
- **Vulnerability Scanning**: Perform vulnerability scanning on the base image to identify potential security issues. Tools like Clair or Anchore can help with this process.
### Stage Isolation
Multistage builds allow you to isolate stages, reducing the attack surface. Ensure that each stage has the minimum required permissions and access to resources.
```dockerfile
# Stage 1: Build
FROM python:3.9-slim as build
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
# Stage 2: Runtime
FROM python:3.9-slim
WORKDIR /app
COPY --from=build /app .
CMD ["python", "app.py"]
```
In this example, the build stage has access to the `requirements.txt` file and the application code, while the runtime stage only has access to the built application.
### Least Privilege Principle
Apply the least privilege principle to each stage by limiting the user permissions and access to resources.
```dockerfile
# Stage 1: Build
FROM python:3.9-slim as build
USER nobody
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
# Stage 2: Runtime
FROM python:3.9-slim
USER nobody
WORKDIR /app
COPY --from=build /app .
CMD ["python", "app.py"]
```
By setting the user to `nobody`, we limit the permissions of each stage, reducing the potential damage in case of a security breach.
### Secure Environment Variables
Environment variables can contain sensitive information such as database credentials or API keys. Ensure that these variables are not exposed in the final image.
```dockerfile
# Stage 1: Build
FROM python:3.9-slim as build
ENV DB_USER=myuser
ENV DB_PASSWORD=mypassword
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
# Stage 2: Runtime
FROM python:3.9-slim
WORKDIR /app
COPY --from=build /app .
CMD ["python", "app.py"]
```
In this example, the environment variables `DB_USER` and `DB_PASSWORD` are set in the build stage but are not carried over to the runtime stage, ensuring they are not exposed in the final image.
### Secure File Permissions
Ensure that file permissions are set correctly to prevent unauthorized access.
```dockerfile
# Stage 1: Build
FROM python:3.9-slim as build
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
RUN chmod 755 /app
# Stage 2: Runtime
FROM python:3.9-slim
WORKDIR /app
COPY --from=build /app .
CMD ["python", "app.py"]
```
By setting the permissions to `755`, we ensure that the application files are executable only by the owner and not by others.
### [Platform Engineering](www.platformengineers.io) and Continuous Integration/Continuous Deployment (CI/CD)
Integrate your multistage builds with your CI/CD pipeline to automate the build and deployment process. This ensures that security checks are performed consistently and efficiently.
### Conclusion
[Multistage builds](https://platformengineers.io/blog/multi-stage-build-for-ci-cd-pipeline-using-dockerfile/) offer a powerful way to optimize Docker images, but they also introduce security risks if not properly managed. By selecting secure base images, isolating stages, applying the least privilege principle, securing environment variables, and setting correct file permissions, you can harden your multistage builds and ensure the security of your final artifact. | shahangita | |

##
#### INTRODUCTION
There are various steps associated with the deployment and connection of a virtual machine in Azure cloud. We will be listing the various steps to deploy a virtual machines with images detailing those processes. With Azure Virtual Machine, you get the flexibility of accessing a virtual platform without buying and maintaining the physical hardware that can run the operation. But you will also need a proper maintenance plan for your Azure Virtual Machine while performing tasks like configuring, patching, parsing, and installing the softwares to run on the virtual machines.
Below are guidelines on how to configure your Virtual machine:
LOG IN:
Logging into Azure Portal, if you do not have an azure account, you will need to sign up for one.
Open your web browser and navigate to https://portal.azure.com.
Sign in using your Azure account credentials.
Select a Resource via the create a resource tab.
Showing the project details, this is a guide to build the various components of the virtual machine from various tabs as highlighted in the above diagram.
## <u>STEP 1. CONFIGURE BASIC SETTINGS</u>
This tab enables you to do the following:
a. **Select subscription and create a Resource Group**
b. **Identify the Virtual Machine instance details:**
(Virtual Machine name, pick the region you want your Virtual Machine to be provisioned, select your preferred availability zone or availability options. You can pick more than one availability zone.
c. **Images:** Enables you to choose an operating system for your virtual machine and there are several ones you can choose from. See below diagram.
For this Virtual machine we have using the linux 8.8.
d. **Size:** This enables you to choose your Virtual Machine configuration. Under “Size,” select the appropriate configuration for your VM based on CPU, memory, and storage requirements.
Carefully review the available sizes and consider your workload needs. See below:
e. **Administrator Account:** An admin account needs to the created for the virtual machine for easy access to log in when required. This can be deployed in two ways Authenticator types.
- SSH KEY
- PASSWORD
A username and Password is also required to gain access:
f. **Inbound Port Rules:** Enables you to select ports. The inbound port rules can be changed on the networking tab in the virtual machine.
## <u>STEP 2. CONFIGURING DISK AND STORAGE</u>
Under “Disks,” choose the OS disk type (Standard HDD, Standard SSD, Premium SSD).
Adjust the OS disk size according to your needs.
Note: Choose Standard SSD for practice purposes
## <u> STEP 3. NETWORKING:</u></u>
This tab enables you to do the following:
a. Choose an existing virtual network and subnet or create new ones.
b. Assign a public IP address if needed.
c. Configure network security groups to control traffic.
Here you can control ports, inbound and outbound connectivity with security rules or place behind an existing load balancing solution.
## <u>
## <u>STEP 4. MANAGEMENT:</u></u>
The management tab is where you create management groups in Azure inform of Hierarchy.You organize subscriptions into containers called management groups and apply governance conditions to the management groups. All subscriptions within a management group automatically inherit the conditions applied to the management group, the same way that resource groups inherit settings from subscriptions and resources from resource groups. Management groups give you enterprise-grade management at a large scale, no matter what type of subscriptions you might have. Management groups can be nested.
HIERARCHY: This hierarchies are done to show the structures of the management layers in Azure for easy management of resources and also to ensure billing are also properly allocated and managed with the Azure resource. Find below some of the hierarchies:
1. ROOT MANAGEMENT GROUP(PARENT): This is at the top of the management layer, it can be classifies as the base or foundation of the management group.You can build a flexible structure of management groups and subscriptions to organize your resources into a hierarchy for unified policy and access management.
2. CHILD MANAGEMENT GROUP: These are subset of the root management groups. 10,000 child management groups can be supported in a single directory.
A management group tree can support up to six levels of depth. This limit doesn’t include the root level or the subscription level.
Each management group and subscription can support only one parent.
3. SUBSCRIPTION: Resource groups are arranged into subscriptions for each management and billing purposes as well. It is a logical container used in managing resources in Azure. It holds details of the resources in Azure like VM, Databases, Networks, storage accounts etc.
4. RESOURCE GROUPS: A resource group is a container that holds related resources for an Azure solution. Resource groups can be used to coordinate changes to related resources, such as deploying updates or deleting resources. For example, if a user deploys an update to a resource group, they can be confident that all the resources in the group will be updated in a coordinated way. When a user is finished with a solution, they can delete the resource group and know that all the resources will also be deleted.
5. RESOURCES: Resources are instances of services that you build, such as virtual machines, storage, and SQL databases.
Below are graphical illustrations to show the management groups as discussed above.
## <u>STEP 5. MONITORING:</u>
In this unit, you explore Azure monitoring capabilities for VMs, and the types of monitoring data you can collect and analyze with Azure Monitor. Azure Monitor is a comprehensive monitoring solution for collecting, analyzing, and responding to monitoring data from Azure and non-Azure resources, including VMs. Azure Monitor has two main monitoring features: Azure Monitor Metrics and Azure Monitor Logs.
A shown in the above diagram, you can set up your alert rules for your virtual machine.
## <u>STEP 6. CREATE & REVIEW:</u>
This tab is for the final setting up of your Virtual Machine
Your Virtual machine is created once validation is passed then you proceed to create VM.
See Below:
To connect your Virtual Machine, you go to the resource tab and click on connect resource, click on connect and your virtual machine will be connected, see diagram below:

Customers... | 0 | 2024-06-14T13:26:41 | https://dev.to/pcloudy_ssts/major-cross-browser-compatibility-issues-faced-by-the-developers-g39 | crossbrowserstrategies, betteruserexperience, mdnsurvey2020 | Introduction
The digital world is constantly growing, and so are the browsers and devices. Customers are no more naive in choosing the best websites to fulfill their needs. So, it becomes necessary for the business to offer them the best user experience and services. There are so many browsers that come with new versions from time to time, making it difficult for the developers to deal with the cross browser compatibility issues. Cross-Browser Compatibility is the most critical aspect that needs special attention of the developers and has always been challenging to handle because of the different working mechanisms of various browsers available. It becomes even more complicated when it involves different device-operating system combinations. So finding how to solve cross browser compatibility issues is a high priority task of the developers and critically important to the business.
What is Cross browser compatibility?
In simple terms, Cross browser compatibility is the ability of the web applications to function consistently on all types of Browser-OS-Device combinations in terms of how they look and behave across as many platforms as possible. As more and more devices, operating systems, and browsers are introduced in the ecosystem, supporting them is quite a challenge for front-end developers. Different users have different browser preferences, and the business cannot force them to switch to another browser type. So, it is important to check your website compatibility even across old legacy browsers. But how can we achieve all of this? It is by focusing on correcting the main [cross browser compatibility issues](https://www.pcloudy.com/5-reasons-why-testing-is-incomplete-without-cross-browser-tests/) faced by the developers. As we progress in this article, we will be able to answer the question as to what are [cross browser compatibility issues and solutions](https://www.pcloudy.com/blogs/top-cross-browser-testing-challenges-and-ways-to-fix-them/).
Key challenges that cause browser compatibility issues for developers.
CSS:
One of the most important aspects that causes cross browser compatibility issues and makes it challenging for the developers to handle is the CSS. Managing CSS is quite complex and unorganized. CSS poses challenges not only for web developers but also for those who develop browsers. With the help of emerging [cross browser strategies](https://www.pcloudy.com/blogs/top-8-strategies-for-successful-cross-browser-testing/) and testing tools, compatibility issues can be tackled easily. There is a common notion among the developers that developers want to focus more on the logical aspects of web development rather than the product.
Google studied the most common cross browser compatibility issues in its most popular sub-branches, such as CSS Flexbox, CSS Position Sticky, Grids, aspect ratio, and CSS transforms. Google, in collaboration with Microsoft, Igalia, and Mozilla has been trying to fix these compatibility issues under the compatibility 2021 project, also called COMPAT2021. Microsoft has taken charge of ameliorating CSS Grids and sub-grids in Chromium and intends to qualify all grid tests.
Issues with Old Browsers:
Legacy browsers like Internet Explorer are outdated and do not support the latest technologies. Even the older versions of other browsers like Mozilla Firefox, Google Chrome, etc., are covered under the old browser category. Technology is constantly evolving, so the CSS has to change with this evolution. But it is easier said than done. It is impossible to implement the CSS updates wholly because, even today, many users use Internet Explorer as their preferred browser. Browsers keep releasing new updated features, but not all users use the updated browser version of their preferred browser. So, these issues need to be tested to avoid browser compatibility issues across all browsers and browser versions for a [better user experience](https://www.pcloudy.com/blogs/how-does-cross-browser-testing-improve-the-user-experience/).
Internet Explorer is obsolete:
There was a time when Internet Explorer (IE) dominated the market. However, with rapid growth in technology, Internet Explorer has become obsolete and does not support features that other browsers do. In the year 2021, Internet Explorer has become a consistent problem for the developers and also a top reason for causing Cross Browser Compatibility issues, as some users still browse the internet on IE. Here is a chart showing the most troublesome browser by the developers (as per MDN Browser Compatibility Report 2020).
Source: [MDN Survey 2020](https://insights.developer.mozilla.org/reports/mdn-browser-compatibility-report-2020.html)
It does not offer multi-class support, the Form layout design is not great and it is also not updated with most of the new properties available elsewhere. Even though Internet Explorer supports CSS Flexbox, it still does not completely solve the problem. It is reported that there will be no support provided for IE 11 desktop from 2022 and beyond for some Windows 10 versions. The IE Mode on MS Edge will be used for accessing and testing IE.
People cannot leave Internet Explorer easily because it has a history. It all started with IE. Internet Explorer was a huge success and, so are its contributions in the past. Many applications on health, accounting, inventory, etc., were built on Internet explorer. Even today, many businesses use IE because switching to modern browsers is expensive. Considering all of the above reasons, developers should understand that IE cannot be ignored, at least currently, and ensure that cross browser compatibility issues are tested on Internet Explorer on priority as well.
Here is a helpful Poster of the Top Cross-Browser Compatibility Issues

JavaScript Compatibility Issues:
JavaScript is not much liked by developers when it comes to solving cross browser compatibility issues. Building web apps depend on JavaScript, despite so many advancements in HTML and CSS. Developers face many challenges while solving browser compatibility issues using JavaScript, mainly when they use features in the web pages that old browsers do not support or while using inappropriate DOCTYPE and the wrong browser sniffing code, etc. There should be a [proper mechanism for processing scripting languages like JavaScript](https://www.pcloudy.com/blogs/test-automation-with-selenium-and-javascript/) to remove cross-browser compatibility issues with JavaScript. A few examples of JavaScript related cross browser compatibility issues are:
– Aligning ECMAScript versions for different browsers
– ECMAScript6 version is supported but only by using Polyfills.
– No JavaScript Native Support available
– Code bloat caused using compiler
– JS Contains multiple modules and packages that slow down the app speed
Solving cross browser compatibility issues with JavaScript is quite problematic for the developers. Hence, it is essential to run cross browser compatibility testing to figure out the cross browser compatibility issues and solutions.
Layout and Styling Compatibility:
A majority of developers are struggling with styling and layout issues. Any business would demand a [well-designed responsive website](https://www.pcloudy.com/blogs/responsive-web-design-testing/). But considering different browsers, platforms, and devices, this becomes unachievable. Achieving long-lasting layout compatibility across various browsers using CSS Flexbox and CSS Grid is not easy. Dynamic websites with responsive design and layouts always have issues like scrolling and viewport sizes support which causes serious cross browser compatibility issues for developers. MDN Browser Compatibility Report 2020 mentions layout and design features that cause cross browser compatibility issues.

Source: [MDN Survey 2020](https://insights.developer.mozilla.org/reports/mdn-browser-compatibility-report-2020.html)
Progressive Web Applications Compatibility issues:
[Progressive Web Apps are non-native apps](https://www.pcloudy.com/blogs/types-of-mobile-apps-native-hybrid-web-and-progressive-web-apps/) that do not have features of a native web app. It cannot take advantage of native functions of the device like accessing camera or file, etc. Managing PWAs has become a pain point for the developers. Google, however, always supports PWAs’ future and provides a list of APIs for PWA development. The PWAs are supported by masked icons but need to carry fixed icons and a personal web app manifest to the browser. Hence, browser compatibility is of utmost importance, even in the case of progressive web apps. Although it is undoubtedly the most disliked task to frequently change the icon images, it can’t be ignored.
Issues during Browser Rendering:
Sometimes, some elements work on one browser but not on the other. These [rendering issues cause problems in cross browser](https://www.pcloudy.com/blogs/testing-fragmentation-and-need-for-cross-browser-compatibility-testing/) compatibility issues. Every browser engine works uniquely while rendering web pages and those browser engines are responsible for everything we see and use on the browsers.
Due to this, the font size and image ratios become abrupt, causing inconsistency in page rendering. Testing websites on so many browsers and their versions seem impossible unless you rely on cloud testing platforms like [pCloudy to make cross browser testing easier](https://www.pcloudy.com/browser-cloud-scale-cross-browser-testing-to-deliver-quality-desktop-web-apps/).
Late adoption of new updates:
Developers keep releasing new features but they are not embraced by browsers immediately. This delay causes many other hurdles in implementation, causing severe cross browser compatibility issues. Whenever there is a delay in the adoption of new features, the lag impacts the quality of the website. CSS Subgrids supported by Mozilla Firefox help to solve the front-end and design problems of the developers. CSS Subgrids is a new CSS feature to build nested grids. There is a grid inside of another grid that helps front-end developers in solving many predictable compatibility issues.
CSS Flexbox Issues:
Another main reason for causing cross browser compatibility issues is CSS Flexbox. As mentioned earlier in this article, CSS Flexbox is covered under the Compat21 project showcasing the problems that impact browser compatibility. Flexbox creates design and layout issues that have been considered the most browser-critical compatibility challenge for developers. Flexbox gives structure to the content of the web page. More than 70 % of the pages contain CSS Flexbox in their source code. CSS Flexbox consists of a list of properties that all browsers do not support currently.
Issues due to Polyfills
It is a piece of code (JS code) used for providing modern browser functionalities to the older browsers that do not natively support them. Polyfills are important to developers because sometimes, many features fail across browsers. So, to cope with that situation, polyfills are used. Why are the developers scared to deal with this messy business of compatibility? It is because thinking about how to solve cross browser compatibility issues is a developer’s job. They can’t get away with cleaning up the mess and keeping the website consistent across different platforms. Polyfills are considered an extra burden for the developers, so they are disliked by the developers, especially in the case of the older browsers. Polyfill is the most current compatibility pain point of 2021.
Why do cross browser issues occur?
Cross-browser issues can arise due to various reasons, and it should be noted that we are discussing problems when items act differently across various devices, browsers, and browsing habits. You ought to have all of the flaws in your code fixed before you even consider cross-browser problems.
Cross browser issues commonly occur because:
Bugs occasionally exist in browsers, or functionalities are implemented differently. While IE4 and Netscape 4 were vying to become the dominant browser in the 1990s, browser firms purposefully implemented things differently from one another in an effort to acquire a competitive advantage. This made life miserable for developers. Today’s browsers are much better at adhering to standards, although occasionally variances and flaws still show.
Different browsers may support technological aspects to varying degrees. This is unavoidable when working with cutting-edge technologies that browsers are only now starting to implement or when supporting very old browsers that are no longer being updated and may have been frozen long before a new feature was ever devised. For instance, modern JavaScript capabilities might not function properly on older browsers if you try to use them on your website. It may be necessary to avoid using older browsers if you need to support them, or you may need to utilize a cross-compiler to convert your code to an outdated syntax when necessary.
Some gadgets could have limitations that make a website perform slowly or display erratically. For instance, a website that looks great on a desktop computer may likely appear small and be challenging to read on a mobile device.
If your website has a lot of large animations, it might run smoothly on a tablet with excellent specifications but sluggish or jerky on a low-end device. To ensure that the experience is smooth across different browsers and devices, it is vital to perform thorough cross-browsers compatibility testing on a wide range of browsers and devices with different screen resolutions, operating systems, browsers, system configurations, etc.
Conclusion
Cross browser compatibility is a critical aspect on which your website’s user experience depends. Dealing with Cross Browser Compatibility issues becomes a nightmare for the developers most of the time. No matter how hard you try to avoid these issues, they will prevail because bugs and development go hand in hand; and developers have no option but to find ways to solve them. We always have to test these cross browser compatibility issues by relying on platforms like pCloudy, which support performing cross-browser compatibility testing of your application and achieving browser compatibility goals. | pcloudy_ssts |

1,888,222 | Automating the Building of VMs with Packer | Introduction There are many reasons why one might need a VM, for example: Learning new... | 0 | 2024-06-14T13:20:34 | https://dev.to/krjakbrjak/automating-the-building-of-vms-with-packer-420 | packer, automaton, qemu, virtualization | ## Introduction
There are many reasons why one might need a VM, for example:
1. **Learning new tools** like [Kubernetes](https://kubernetes.io/) and explore different ways of installing it, experimenting with various plugins, etc. If these tools are installed natively on the host and something goes wrong, it might require resetting the host.
2. **Creating clean, reproducible builds** for your project.
Setting up the VM and all the necessary tools usually takes time and effort. Automating this process would be much faster, more convenient, and significantly less error-prone. While one can write scripts to set up VMs, this approach requires new implementations for each virtualization software technology. Various tools exist for this purpose, but I am going to use [Packer](https://www.packer.io/) because it is open source, widely adopted, and well-supported. It supports all modern VM providers, such as [VirtualBox](https://www.virtualbox.org/), [VMware](https://www.vmware.com/), [KVM](https://linux-kvm.org/page/Main_Page), and various cloud providers. It is also highly configurable and can be extended if you need functionality not yet supported by the tool.
Another important tool from the same organization is [Vagrant](https://www.vagrantup.com/), which provides extra help in running VMs built with Packer. Of course, the choice of a VM provider is also very important, as some VM providers may not be supported on certain platforms. For example, there are no VMware or VirtualBox releases that support Apple Silicon. However, [QEMU](https://www.qemu.org/) is supported on most platforms, including Apple Silicon, which is why this provider was chosen here.
The next important question is choosing the Linux distro. One of the most popular Linux distros is [Ubuntu](https://ubuntu.com/), which will be considered here.
## Unattended installation
Traditionally, to support unattended installations, so-called _preseed files_ were used. However, in recent releases, these have been deprecated in favor of [autoinstall](https://canonical-subiquity.readthedocs-hosted.com/en/latest/intro-to-autoinstall.html), a tool that allows for unattended OS installations with the help of cloud-init. Instead of booting an ISO image and manually selecting options, one can describe the system installation in a YAML file (the reference can be found here) and boot the system with specific options. Internally, cloud-init will start and check for special files, meta-data, and user-data, in the specified location. The only drawback is that this solution is available for server releases. However, here is a [link](https://github.com/canonical/autoinstall-desktop/blob/main/README.md) to official Canonical user-data files that can be used as a reference for installing the desktop environment.
The following is an example of `user-data` that was used to prepare the server:
```YAML
#cloud-config
autoinstall:
version: 1
locale: en_US
network:
version: 2
ethernets:
all:
match:
name: en*
dhcp4: true
ssh:
install-server: yes
allow-pw: yes
user-data:
ssh_pwauth: True
users:
- name: packer
plain_text_passwd: packer
sudo: ALL=(ALL) NOPASSWD:ALL
shell: /bin/bash
groups: sudo
lock_passwd: false
```
It has a very basic structure where basically only the user is specified. Extra packages can be added here as well, like compiler toolchain, etc. The full reference for the format of this file can be found [here](https://canonical-subiquity.readthedocs-hosted.com/en/latest/reference/autoinstall-reference.html). What is worth mentioning here is the network configuration. When network configuration is not specified here then (on my system) the wrong configuration is added automatically, that does not match any interface. That is why a match for all Ethernet interfaces (`en*`) was added. See [this](https://github.com/systemd/systemd/blob/ccddd104fc95e0e769142af6e1fe1edec5be70a6/src/udev/udev-builtin-net_id.c#L29) for more information about predictable interface names.
After that the only thing that is left to do is to tell `autoinstall` where this configuration files can be found. With Packer it is very easy as it will start this server automatically. The following is the relevant part of the packer build config:
```HCL2
http_directory = "http"
boot_command = [
"c",
"linux /casper/vmlinuz --- autoinstall ds='nocloud-net;s=http://{{ .HTTPIP }}:{{ .HTTPPort }}/server' ",
"<enter><wait>",
"initrd /casper/initrd<enter><wait>",
"boot<enter>"
]
```
It specifies the folder which packer's server will use to serve the `autoinstall` config files, and it also specifies the boot command. That is basically everything that is required to build the Ubuntu server VM.
There are also releases of so-called [cloud images](https://cloud-images.ubuntu.com/), which are Ubuntu images optimized to run in the public cloud. These images are already shipped with the `cloud-init` installed. And that makes it even easier to unattendedly install the OS. According to the [documentation](https://cloudinit.readthedocs.io/en/21.1/topics/datasources/nocloud.html)
> the data source `NoCloud` allows the user to provide user-data and meta-data to the instance without running a network service (or even without having a network at all).
`meta-data` can be passed via SMBIOS “serial number” option. Since QEMU builder is used here, the `cloud-init` config can be passed via `-smbios` option (relevant part of a packer template):
```
qemuargs = [
["-smbios", "type=1,serial=ds=nocloud-net;s=http://{{ .HTTPIP }}:{{ .HTTPPort }}/cloud/"]
]
```
Finally, after the VMs images were prepared and built it is time to start them. ANd to make it easy, a template `Vagrantfile` is generated with the help of [`shell-local`](https://developer.hashicorp.com/packer/docs/post-processors/shell-local) post-processor:
```
Vagrant.configure(2) do |config|
config.vm.box = "${var.vm_name}.box"
config.vm.provider :qemu do |qe, override|
override.ssh.username = "packer"
override.ssh.password = "packer"
qe.qemu_dir = "${var.qemu_dir}"
qe.arch = "${var.qemu_arch}"
qe.machine = "type=${var.machine},accel=${var.accelerator}"
qe.cpu = "host"
qe.net_device = "virtio-net"
qe.smp = 4
qe.memory = "8192M"
qe.ssh_port = "${var.qemu_ssh_port}"
end
config.vm.synced_folder ".", "/vagrant", disabled: true
end
```
All that is left to do is go the build folder and type `vagrant up`.
You can find the complete code used in this article [here](https://github.com/krjakbrjak/packer_templates/tree/main).
## Conclusion
Packer is a powerful and versatile tool for automating the creation of virtual machine images. Its compatibility with a wide range of platforms and VM providers makes it a valuable asset for any developer. Whether you are looking to learn new technologies, ensure clean and reproducible builds, or streamline the system setup process, Packer can significantly enhance your workflow.

1,887,400 | Integrating React QuillJs with React Hook Form | Quilljs is a free, open-source library that lets developers easily add rich text editing capabilities... | 0 | 2024-06-14T13:10:29 | https://dev.to/arnaudfl/integrating-react-quilljs-with-react-hook-form-2ghj | react, quilljs, typescript, reacthookform | **Quilljs** is a free, open-source library that lets developers easily add rich text editing capabilities to their web applications. It provides a familiar WYSIWYG (What You See Is What You Get) editing experience, similar to popular word processors, allowing users to format text, add images, and create interactive content. It's also known for being customizable, so developers can tailor it to their specific needs.
While **React Quill** was once a popular option for adding rich text editing to React applications, there are a couple reasons why it might not be the most relevant choice these days:
- **Out of Date:** React Quill hasn't had major updates in over two years. This raises concerns about compatibility with newer React versions and security risks.
- **Quill v2 Issues:** There's a new version of Quill (v2), but React Quill doesn't seem to work with it smoothly, potentially causing problems.
- **Outdated Techniques:** React Quill might use older methods for handling the web page structure (DOM manipulation) that aren't ideal for modern React development.
There's a new React library called **React Quilljs** that's actively maintained and integrates well with React projects.
I'll show you how to use React Quilljs with React Hook Form in a TypeScript project. While it might not be the ultimate solution, it works!
## Install dependencies
```bash
npm install react-quilljs quill
npm install -D @types/quill
npm install react-hook-form
```
For other configuration options, check out the [react-quilljs documentation](https://github.com/gtgalone/react-quilljs).
## Usage
First, create a file named `App.tsx` in the root directory. This file will be used to render the editor. Be caution when using this file like this, because it will not work without the `Layout.tsx` component (see the project on GitHub)
{% gist https://gist.github.com/arnaudfl/bc7980564780ff3f36153e761768beb8 %}
Then, create a file named `Editor.tsx` in the `components` directory. This file will be used to render the editor.
{% gist https://gist.github.com/arnaudfl/07fdbc9311a4746cbd7466840de96ed4 %}
## Conclusion
You can view results on [CodeSandbox](https://codesandbox.io/p/sandbox/react-hook-form-quilljs-d5lx6f)

1,888,582 | Handling Actions Class in Selenium and its usage | Selenium is considered one of the best testing tools for automating web applications. It is a... | 0 | 2024-06-14T13:08:35 | https://dev.to/pcloudy_ssts/handling-actions-class-in-selenium-and-its-usage-3c86 | besttestingtools, multipleinteractions, selenium, seleniumwebdriver | [Selenium ](https://www.pcloudy.com/selenium-testing-for-effective-test-automation/)is considered one of the [best testing tools](https://www.pcloudy.com/top-10-test-automation-frameworks-in-2020/) for automating web applications. It is a powerful tool with built-in features to support all types of actions related to the keyboard and mouse. The user performs various operations while exploring the web like clicking any button, entering text, Double click, right-click, drag-and-drop, select from the drop-down menu, resize, etc. Actions Class in Selenium is required to perform such single or [multiple interactions](https://www.pcloudy.com/blogs/digital-testing-for-multi-experience-development-apps/). Also, Selenium Actions are used to automate such interactions with the browser through mouse and keyboard using automation scripts. Even to test any application using [Selenium](https://www.pcloudy.com/blogs/the-importance-of-parallel-testing-in-selenium/), these actions are performed on the web application using actions class. Let us understand how to use the actions class in Selenium and what it is all about.
What is Actions Class in Selenium?
Actions class includes a set of actions that a user performs on the web application using a Keyboard or a Mouse. It comes as a built-in feature of [Selenium Webdriver](https://www.pcloudy.com/blogs/test-automation-using-selenium-chromedriver/) for emulating advanced user interactions API. The interactions like clicking a button, entering a text in the search bar, drag-and-drop, and so on. These actions that are performed through Mouse and the keyboard; are automated using Selenium Actions. Selenium Actions are the main elements that are responsible for the operations performed through these input devices. It is quite easy to understand how to use the Actions class in Selenium but the difficult part is to execute it. Ideally, the Selenium actions class which is the API for invoking action events, should be used instead of using input devices. A general form of code to perform actions class uses the following syntax:
Actions action = new Actions(driver); – To configure the action
action.moveToElement(element).click().perform(); -To click on the element
Different methods under the Actions class
There are two types of actions mainly performed in the [web browser using Selenium](https://www.pcloudy.com/blogs/best-unit-testing-frameworks-to-automate-your-desktop-web-testing-using-selenium/), namely:
Mouse Actions
Keyboard Actions
Once you discover the Actions Class, it becomes easy to implement their use cases. Let’s discuss them in detail.
Mouse Actions:
There are several Mouse Actions provided by Actions Class, namely:
click() – To click current location
doubleClick() – To Perform double click on the mouse location
clickAndHold() – To Perform mouse click without release.
contextClick() – To perform right mouse click on the current mouse location
moveToElement(WebElement target) – To move the mouse pointer to the centre of the target location
dragAndDrop(WebElement source, WebElement target) – To drag the element from the source and
drop to the target location.
dragAndDropBy(source, xOffset, yOffset) – To click and hold on current location then shifts by a
given offset value and then release the mouse (X = Shift Horizontally, Y= Shift Vertically)
release() – To release the left mouse button on current location
Keyboard Actions:
sendKeys(sendKeys(WebElement target, java.lang.CharSequence… keys) : To send a series of keys to the element
keyUp(WebElement target, java.lang.CharSequence key) : Performs key release after focusing on the target
keyDown(WebElement target, java.lang.CharSequence key) : To perform key press without release.
Apart from the methods mentioned above, many other methods can be used based on the requirement, as shown in the screenshot below:
Source: [https://www.toolsqa.com/](https://www.toolsqa.com/)
Actions Class Vs Action Class
There is another concept called Action Class which is different from Actions Class. If you notice the screenshot above, there are two blue lines that represent Action Class returned by Build Method. So, we can say that Actions Class is a class made by builder design pattern, an API that emulates the user interactions. Whereas, Action Class is simply an interface that represents single user interactions to perform a series of actions created by Selenium Actions Class. Two of the most used methods under Action Class are perform() – to perform action on the elements and build() – for execution and compilation.
How to handle Actions in these Selenium Actions Class?
The capability of Actions Class in Selenium to perform an extensive set of interactions is one of its strengths. We need to follow a distinct format and understand its usage and methods. Points to remember:
First, let’s create an Object of the Actions class ‘Action’.
Use Selenium Webdriver to focus on the target element : action.moveToElement(element).build().perform();
Use build.perform() method to execute and compile Actions class.
Then choose to apply various methods under Actions class for performing interactions like clicking, dragging, selecting, etc.
Let us discuss all the steps in detail and implement Actions class in Selenium automation Script.
A. Mouse Click() Method :
There are different mouse actions to focus on. The mouse clicks performed by actions class are targeted either on an element or on the current cursor location. Let us explain this using an example of a product search on a shopping website where the user clicks on the search icon:
import static org.testng.Assert.assertEquals;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
//specify the URL of the webpage
driver.get("https://www.amazon.in/");
//maximise the window
driver.manage().window().maximize();
//create an object for the Actions class and pass the driver argument
Actions action = new Actions(driver);
//specify the locator of the search box in which the product has to be typed
WebElement elementToType = driver.findElement(By.id("twotabsearchtextbox"));
//pass the value of the product
action.sendKeys(elementToType, "iphone").build().perform();
//specify the locator of the search button
WebElement elementToClick = driver.findElement(By.className("nav-input"));
//perform a mouse click on the search button
action.click(elementToClick).build().perform();
//verify the title of the website after searching the product
assertEquals(driver.getTitle(), "Amazon.in : iphone");
driver.quit();
}
B. ContextClick() and DoubleClick() Method
The ContextClick() method is used when the user performs a right-click at the current mouse location. It is also called the right-click method. DoubleClick() Method is used when there is a need to click the button twice. Action Class in Selenium is capable enough to perform both these methods by using the following code for both the actions:
import static org.testng.Assert.assertEquals;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
public class clickDemo {
public static void main(String[] args) {
// specify the driver location
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Shalini\\Downloads\\Driver\\chromedriver.exe");
// instantiate the driver
WebDriver driver = new ChromeDriver();
//specify the URL of the website
driver.get("https://www.amazon.in/");
//maximise the window
driver.manage().window().maximize();
WebElement element = driver.findElement(By.xpath("//*[@id=\"nav-xshop\"]/a[1]"));
Actions action = new Actions(driver);
action.doubleClick(element).build().perform();
assertEquals(driver.getTitle(), "Mobile Phones: Buy New Mobiles Online at Best Prices in India | Buy Cell Phones Online - Amazon.in");
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
action.contextClick().build().perform();
driver.quit();
}
}
C. moveToElement() Method:
This method is used when the user wants to move the mouse pointer to the center of a particular web element.
You must have seen in some of the websites where the menu lists appear only once you move the cursor over the Main Menu. In this situation, the Actions class in Selenium provides the moveToElement method. Here, the input parameter is the target web element, where X and Y coordinates values are put as parameters.
Let’s use the below example to explain the scenario. Here is a snapshot of the [pCloudy ](https://www.pcloudy.com/)Website. Hover over the Resources Tab and click on the Blog section.
pCloudy blog
To Automate the above scenario, we use the following code:
import static org.testng.Assert.assertEquals;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
public class MoveTest {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Shalini\\Downloads\\Driver\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
//specify the pcloudy URL
driver.get("https://www. pcloudy.com/");
assertEquals(driver.getTitle(), "Most Powerful Cross Browser Testing Tool Online | pcloudy");
driver.manage().window().maximize();
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
//specify the locator of the Resources menu
WebElement element = driver.findElement(By.xpath("//*[@id=\"navbarSupportedContent\"]/ul/li[4]/a"));
Actions act = new Actions(driver);
//mouse hover the Resources element
act.moveToElement(element).build().perform();
//specify the locator for the element Blog and click
driver.findElement(By.linkText("Blog")).click();
assertEquals(driver.getCurrentUrl(), "https://www.pcloudy.com/blog/");
//verify the page title after navigating to the Blog section
assertEquals(driver.getTitle(), "pCloudy | 10 Best CI Tools in 2020 Blog");
driver.close();
}
D. DragAndDrop(WebElement source,WebElement target) Method:
As the name suggests, this method is used when there is a need to drag the element from original location to the target location. Using Actions class in Selenium, this can be performed using
-dragAndDrop(WebElement source,WebElement target) method
-clickAndHold(WebElement source) ? moveToElement(WebElement target) ? release actions
This is for manual dragging and dropping of the element from the source to the final location.
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
public class ActionsTest {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Shalini\\Downloads\\Driver\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://www.w3schools.com/html/html5_draganddrop.asp");
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
driver.manage().window().maximize();
Actions action = new Actions(driver);
WebElement source = driver.findElement(By.xpath("//*[@id=\"drag1\"]"));
WebElement destination = driver.findElement(By.xpath("//*[@id=\"div2\"]"));
action.clickAndHold(source).moveToElement(destination).release().build().perform();
driver.quit();
}
E. sendKeys() Method :
This Actions Class in Selenium allows us to implement this method for typing certain values in the application. For example, searching the name of the product in the search bar of an e-commerce website. The Following code can be used for this scenario.
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
public class sendKeysDemo {
public static void main(String[] args) {
//specify the driver location
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Shalini\\Downloads\\Driver\\chromedriver.exe");
//instantiate the driver
WebDriver driver = new ChromeDriver();
//specify the URL of the webpage
driver.get("https://www.google.com/");
//maximise the window
driver.manage().window().maximize();
//specify the locator of the search box
WebElement element = driver.findElement(By.xpath("//*[@id=\"tsf\"]/div[2]/div[1]/div[1]/div/div[2]/input"));
//create an object for the Actions class and pass the driver argument
Actions action = new Actions(driver);
//pass the product name that has to be searched in the website
action.sendKeys(element, "iphone").build().perform();
driver.quit();
}
}
Upon noticing, you would realize that here build() and perform() commands are used at the end. This is because the former creates a combined action to perform all intended actions together whereas, the latter is used to perform predefined series of actions.
SendKeys()Method is also used to send other keys like CTRL, ALT, SHIFT, etc., apart from sending text as in the previous case. In this case, when we type the product name on the shopping website, we would hit Enter/Return on the Keyboard. Below code shows how the actions class in Selenium allows performing search only through the keyboard:
import static org.testng.Assert.assertEquals;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
public class enterDemo {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\Shalini\\Downloads\\Driver\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("https://www.amazon.in/");
driver.manage().window().maximize();
Actions action = new Actions(driver);
//specify the locator of the search box
WebElement elementToType = driver.findElement(By.id("twotabsearchtextbox"));
//pass the name of the product
action.sendKeys(elementToType, "iphone").build().perform();
//pass the Enter value through sendKeys
action.sendKeys(Keys.ENTER).build().perform();
assertEquals(driver.getTitle(), "Amazon.in : iphone");
driver.close();
}
}
F. KeyUp() / KeyDown () Method :
KeyUp() method is used to release the keys pressed earlier using the keyDown() method. KeyDown() Method performs Keypress without release. These methods serve cases like text conversion from Upper to lowercase, copying the text from the source location and pasting it to the final location, up and down web page scrolling, selecting values. In Selenium Test Automation, this method is the most used [Actions class in Selenium](https://www.pcloudy.com/handling-actions-class-in-selenium-and-its-usage/). Discussed below:
Text Conversion to Upper Case: Pressing SHIFT Key and entering text without releasing SHIFT
Up/Down Page Scrolling: Scrolling from the top or bottom of the page
Copy/Paste: Copying Text from Source, Pasting it at the target location
Page Refresh: perform basic page refreshing
Here is the code to show how these Keyboard Actions are performed.
package SeleniumCommands;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.time.Duration;
import java.util.List;
public class MouseHover {
public static void main(String[] args) throws InterruptedException {
WebDriver driver = new ChromeDriver();
driver.get("https://in.ebay.com/");
driver.manage().window().maximize();
Actions action = new Actions(driver);
WebElement element = driver.findElement(By.linkText("Electronics"));
//Mouse hover actions on an element using Actions Class:
action.moveToElement(element).build().perform();
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
wait.until(ExpectedConditions.visibilityOfElementLocated(By.linkText("Smart Watches")));
WebElement element2 = driver.findElement(By.linkText("Smart Watches"));
action.moveToElement(element2);
//Mouse hover actions on a sub-element using Actions Class:
action.click().build().perform();
System.out.println(driver.getCurrentUrl());
}
}
Error Handling
When working with Selenium’s Actions class, you might encounter various exceptions and errors. It is important to handle these exceptions gracefully to ensure that your test script does not break unexpectedly. Here are common errors and ways to handle them:
NoSuchElementException: This exception is thrown when an element is not found on the page. You can handle this by using try-catch blocks and providing an alternative flow or logging the error.
try {
WebElement element = driver.findElement(By.id(“nonExistentElement”));
} catch (NoSuchElementException e) {
System.out.println(“Element not found: ” + e.getMessage());
}
StaleElementReferenceException: Occurs when a reference is made to an element that is no longer present on the DOM. This can be handled by re-trying to find the element.
try {
action.click(someElement).perform();
} catch (StaleElementReferenceException e) {
someElement = driver.findElement(By.id(“elementId”));
action.click(someElement).perform();
}
TimeoutException: When an action takes longer than the predefined time. Using WebDriverWait can often solve these issues by waiting for an element to be present, visible, or clickable.
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.id(“elementId”)));
action.click(element).perform();
WebDriverException: General exception for when WebDriver is not able to execute the command. Check for the correct setup of your WebDriver, and the compatibility of the browser driver with the browser version.
Always include detailed logging and meaningful messages in your error handling code. This helps in debugging and maintaining the test scripts.
Advanced Use Cases
Here are some advanced use cases where the Actions class can be very useful:
Chain Multiple Actions: You can simulate complex user interactions by chaining multiple actions together in a single script.
Actions action = new Actions(driver);
action.keyDown(Keys.CONTROL)
.click(element1)
.click(element2)
.keyUp(Keys.CONTROL)
.build()
.perform();
This example holds down the control key and performs multiple clicks, simulating a user selecting multiple items with the control key held down.
Dragging an Element by an Offset: Instead of dragging an element to another element, you can also drag it by an offset.
Actions action = new Actions(driver);
action.dragAndDropBy(draggableElement, 50, 100).perform();
This drags the element 50 pixels to the right and 100 pixels down.
Context Click (Right Click): You can simulate a right-click on an element which may open a context menu.
Actions action = new Actions(driver);
action.contextClick(element).perform();
Simulating Mouse Hover and Selecting from Dropdown: Sometimes, menus are displayed only when you hover over an element. Actions class can be used to simulate mouse hover and then select from the dropdown.
Actions action = new Actions(driver);
action.moveToElement(menuElement).perform();
// Waiting for the menu to be displayed and then select the item
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement subMenuElement = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id(“submenuId”)));
action.moveToElement(subMenuElement).click().perform();
Remember that when working with complex actions, the behavior might differ between browsers. It’s important to thoroughly test the script in all browsers you are targeting.
Conclusion:
Role of Selenium Actions Class is Pivotal in [automated testing](https://www.pcloudy.com/automation-execution/). We understand the simplified ways to simulate basic user interactions on the applications. It allows the testers to observe the software behavior in a real environment and take corrective measures to optimize the user experience. As we conclude, we understand the concept of the Actions class in Selenium, the difference between Action Class and Actions Class, how to use action class in Selenium, and various methods that it covers with examples and code snippets. We recommend a cloud-based Selenium Grid to speed up the release cycles and make the entire process impactful. pCloudy provides a cloud-based browser platform to perform hassle-free cross-browser testing on several operating systems and browsers.

## Explainer
The answer is "The answer is".
Also called a _self-replicating program_, a quine is a computer program that outputs its own source code. The sentence above tries to mimic one. Its practicality can be arguable, but it's an amusing metaprogramming concept.
## Additional Context
Here is an example in JavaScript, adapted from Dylan Beattie's beautiful talk [_The Art of Code_](https://www.youtube.com/watch?v=6avJHaC3C2U&t=1802s):
```js
(f = () => console.log(`(f = ${f})()`))()
```
When you run it, the output is:
```
(f = () => console.log(`(f = ${f})()`))()
```

1,886,323 | Function fitting in Go | In Go, as in most programming languages, the return value of a function g() can be used as an... | 0 | 2024-06-14T13:07:39 | https://dev.to/qustavo/function-fitting-in-go-210f | go, programming, coding | In Go, as in most programming languages, the return value of a function `g()` can be used as an argument of another function `f()`.
```go
package main
func g() int { return 42 }
func f(n int) { println(n) }
func main() {
f(g()) // prints `42`
}
```
Now, what happens when `g()` returns more than one value, can we still do that?
Short answer is _"yes, but"_
## Some Theory
The Go spec treats this as a special case:
> #### [Calls](https://go.dev/ref/spec#Calls)
>
> As a special case, if the return values of a function or method `g` are equal in number and individually assignable to the parameters of another function or method `f`, then the call `f(g(_parameters_of_g_))` will invoke `f` after binding the return values of `g` to the parameters of f in order.
Effectively this piece of code will work too.
```go
package main
func g() (int, int) { return 0, 0 }
func f(int, int) {}
func main() {
f(g())
}
```
Both the number and type of arguments that a function returns MUST be equal (or _fit_) into the arguments received by a function, although there is nuance.
> […] If f has a final ... parameter, it is assigned the return values of g that remain after assignment of regular parameters.
This means that we can
```go
package main
func g() (int, int, int) { return 1, 2, 3}
func f(a int, n ...int) {
fmt.Printf("a: %d, n: %v", a, b)
}
func main() {
f(g()) // prints `a: 1, n: [2, 3]`
}
```
In the example above, `g()` returns a larger number values than the number of arguments received by `f()`. This will work a long as the types match.
It is important to note that `f()` cannot receive any other argument than those returned by `g()`, this make both function signatures to be linked, meaning that `g()`'s return values fit into `f()`'s
### Practical Usage
There is a common Go idiom that leverages this property by defining a _Must_ function. A _Must_ function takes the return values of a function `f()` and panics when there is an error. For Must to work `f()` must return zero or more arguments followed by a final error.
Take for instance [template.Must](https://pkg.go.dev/html/template#Must) helper that works in conjunction with the `Parse` function family ([ParseFS](https://pkg.go.dev/html/template#ParseFS), [ParseFiles](https://pkg.go.dev/html/template#ParseFiles), [ParseGlob](https://pkg.go.dev/html/template#ParseGlob) and so on), it will panic when the returned error is not nil.
This idiom can be found outside the standard library too like google's UUID, where [NewRandom()](https://pkg.go.dev/github.com/google/uuid#NewRandom) _fits_ in [Must()](https://pkg.go.dev/github.com/google/uuid#Must).
Although the examples presented use concrete types, making this generic should be trivial:
```go
func Must[T any](t T, err error) {
if err != nil {
panic(err)
}
return t
}
```
(Un)fortunately we cannot make this generic enough and let our helper handle an arbitrary number of arguments AND types arguments is returned, meaning that if func f() (string, string, error) we’d need to create a new helper with increased arity for every function returning an extra argument.
```go
func Must2[T1, T2 any](t1 T1, t2 T2, err error) (T1, T2) {
return t1, Must(t2, err)
}
// And we can keep going.
func Must3(T1, T2, T3 any)(t1 T1, t2 T2, t3 T3, err error) (T1, T2, T3) {
return t1, t2, Must(t3, err)
}
```
### Wrapping up
So why is this useful?
`Must` is intended for use in variable initialization which usually involves some degree of error handling. Error handling in Go has always been a hot topic and there are many angles from which we can look at it, any technique (no matter how small it is) will make our understanding of the problem better. It is also important to notice that being idiomatic in Go is key to writing code that will be easy to maintain, so if there’s is an idiom for handling errors, let’s use it.

1,888,579 | Test Data Management: Ensuring Quality and Efficiency in Software Testing | In the landscape of software development, ensuring the quality and reliability of applications is... | 0 | 2024-06-14T13:07:34 | https://dev.to/keploy/test-data-management-ensuring-quality-and-efficiency-in-software-testing-21mh | javascript | In the landscape of software development, ensuring the quality and reliability of applications is paramount. One of the critical components in achieving this goal is effective test data management (TDM). Test data management encompasses the processes, tools, and strategies used to create, maintain, and manage the data required for testing applications. This article delves into the importance of TDM, the challenges it addresses, the methodologies employed, and the tools that facilitate its implementation.
The Importance of [Test Data Management](https://keploy.io/test-data-generator)
1. Ensuring Test Coverage: Comprehensive test data is crucial for covering a wide range of scenarios, including edge cases, boundary conditions, and typical user interactions. Effective TDM ensures that all aspects of the application are tested thoroughly.
2. Data Privacy and Compliance: With increasing regulations around data privacy (such as GDPR and CCPA), managing test data to ensure compliance is vital. TDM helps in creating and managing data that adheres to these regulations, protecting sensitive information while allowing thorough testing.
3. Improving Test Efficiency: Proper TDM reduces the time and effort required to generate and maintain test data. It streamlines the testing process, allowing for quicker iterations and faster delivery of quality software.
4. Maintaining Data Consistency: TDM ensures that test data is consistent across different environments and test cycles. This consistency is crucial for reliable and repeatable testing outcomes.
Key Components of Test Data Management
1. Data Generation: Creating test data that mimics real-world scenarios is the first step in TDM. This includes generating data that covers all possible use cases, from typical usage patterns to edge cases.
2. Data Masking: Protecting sensitive information by masking or anonymizing production data. Data masking ensures that real data is used for testing without exposing sensitive information, maintaining data privacy and compliance.
3. Data Subsetting: Extracting a representative subset of data from a larger production database. This reduces the volume of data while ensuring that the subset is comprehensive enough for effective testing.
4. Data Refresh and Versioning: Keeping test data up-to-date and managing different versions of data sets. Regular refreshes ensure that the test data remains relevant and aligned with the latest production data.
5. Data Allocation: Assigning appropriate data sets to different testing teams and environments. Proper data allocation ensures that testers have the necessary data for their specific testing needs without conflicts or duplications.
Challenges in Test Data Management
1. Data Privacy and Security: Managing sensitive data while ensuring privacy and security is a significant challenge. Data breaches or leaks during testing can have severe repercussions.
2. Data Volume: Handling large volumes of data, especially in complex systems, can be cumbersome. Managing this data efficiently without compromising performance is crucial.
3. Data Consistency: Ensuring that test data remains consistent across various environments and test cycles requires meticulous planning and execution.
4. Maintenance Overhead: Keeping test data aligned with evolving application requirements and changes in production data involves ongoing maintenance and updates.
Methodologies for Effective Test Data Management
1. Automated Data Generation: Utilizing tools to automatically generate test data based on predefined rules and templates. Automated data generation saves time and ensures a consistent approach to data creation.
2. Data Masking Techniques: Implementing robust data masking techniques to anonymize sensitive information. This includes techniques like shuffling, substitution, and encryption.
3. Data Subsetting Strategies: Using smart subsetting strategies to create representative data sets that are smaller in size but comprehensive in coverage.
4. Version Control for Test Data: Implementing version control for test data sets to track changes, manage different versions, and ensure consistency across test cycles.
5. Environment Synchronization: Ensuring synchronization between test environments to maintain data consistency and reduce discrepancies in testing outcomes.
Tools for Test Data Management
1. Informatica Test Data Management: Provides a comprehensive solution for data masking, subsetting, and generation. It ensures data privacy and compliance while offering robust data management capabilities.
2. CA Test Data Manager: A powerful tool for creating, maintaining, and provisioning test data. It supports data masking, subsetting, and synthetic data generation.
3. IBM InfoSphere Optim: Focuses on managing test data efficiently by providing capabilities for data subsetting, masking, and archiving. It ensures compliance and optimizes storage usage.
4. Delphix: Offers dynamic data masking and virtualization, allowing for quick provisioning and updating of test environments. Delphix accelerates testing cycles and ensures data privacy.
5. Redgate SQL Provision: Specializes in database provisioning and data masking for SQL Server databases. It ensures secure, consistent, and efficient test data management.
Best Practices for Test Data Management
1. Define Clear Requirements: Clearly define the test data requirements based on the application’s functionalities and expected user scenarios. This helps in generating relevant and comprehensive test data sets.
2. Implement Data Masking Early: Incorporate data masking early in the TDM process to ensure that all sensitive information is protected from the outset.
3. Automate Where Possible: Use automation tools for data generation, masking, and subsetting to improve efficiency and reduce manual effort.
4. Regular Data Refreshes: Keep test data up-to-date with regular refreshes to ensure it remains relevant and aligned with production data.
5. Monitor and Audit: Implement monitoring and auditing mechanisms to track the usage and changes in test data. This helps in maintaining data integrity and compliance.
Conclusion
Effective test data management is a cornerstone of successful software testing. It ensures comprehensive test coverage, protects sensitive information, and improves the efficiency and reliability of the testing process. By leveraging automated tools and following best practices, organizations can overcome the challenges associated with TDM and deliver high-quality software that meets user expectations and complies with regulatory standards. As the complexity of software systems continues to grow, the importance of robust TDM will only increase, making it an indispensable part of the software development lifecycle. | keploy |

we use conditional statement in javascript when we want to perform different actions based on different conditions. They are the fundamental part of programming and use when certain conditions are either true or false. uderstanding them will enable you to use them effectively and allows you to execute specific blocks of code based on conditions.
The main type of conditional statement in Javascript are;
1. If statement
2. If else Statement.
3. If else, if else statement (else if).
4. Switch statement.
5. Tenary operator (Conditional Operator)
**The If statement**
The if statement in javascript is the most basic type of expression. it is a statement that always returns true, when an expression is false it will not evalutae the expression, it will only be executed when it is true.
```js
const samuelAge = 18;
const felixAge = 12;
if (samuelAge > felixAge) {
console.log("Samuel is the eldest brother of Felix");
}
// output Samuel is the eldest brother of Felix\
```
The output here will be Samuel is the eldest brother of felix, because the conditions evaluate to be true. However when the statement is false the code will not run.
```js
const felixAge = 12;
const samuelAge = 18;
if (felixAge > SamuelAge) {
console.log("Felix is older than Samuel");
}
// output: no output because it is false
```
This code will have no output, since felixAge is less than (<) samuelAge. This will evaluate to false and will be ignored because it is not a truthy statement.
The if keywords is used to create an if statement, which is then followed by a condition enclosed in parenthesis and the code to be executed enclosed in curly brackets. it may be expressed simply as if () {}.
**If else Statement**
if else statement is applicable when we want the conditions to be either true or false. when we want something to occur in the event that the condition is not fulfilled i.e. false then we use if else statement. the if statement comes first and the else statement comes follows and has no condition in parathesis.
```js
const felixAge = 12;
const samuelAge = 18;
if (felixAge > samuelAge) {
console.log("Samuel is the eldest brother of Felix");
} else {
console.log("Felix is the eldest brother of Samuel");
}
//output: Felix is the eldest brother of Samuel
```
This statement above is false!!! when executing an if statement they are always true but when the if statement are not true the codes moves on to the else statement and execute the statement that is false. The condition is false because felix is not older than samuel.
**If else if else (The else if Statement)**
If else statement is nested to create an else if clause. it is often use for conditions that are true or false. The else if statement can evaluate multiple possibe outcomes or options with different block of code in a single decision-making structure.
```js
let cgpa = 4.5
if (cgpa >= 4.5) {
console.log("First Class")
} else if (cgpa >= 3.5) {
console.log("Second Class Upper")
} else if (cgpa >= 2.4) {
console.log("Second Class Lower")
} else if (cgpa >= 1.5) {
console.log("Third Class")
} else {
console.log("pass")
}
// output: First class
```
we can have so many else if statemets as necessary but then in the case of many else if statement, the switch statement can be preferred for readability, understandability, and clarity in the looks of code.
**The Switch Statement**
```js
let firstClassCgpa = 4.5
function cgpaClassification (cgpa) {
switch(true) {
case cgpa >= 4.5:
console.log ("congratulations you have archived a first class");
break;
case cgpa >= 3.5:
console.log ("well done you have archived a second class upper");
break;
case cgpa >= 2.4:
console.log ("second class lower");
break;
case cgpa >= 1.5:
console.log("Third Class");
break;
default:
console.log("pass");
}
}
cgpaClassification(firstClassCgpa)
// output: congratulations you have archived a first class
```
The case keyword is where the expression will be defined regarding the block of code to be executed, The break keyword in the switch statement indicates that javascript should stop the execution inside the switch block when the match case is valid, if there is no break keyword the execution will continue to the next case or default. The default shows that if it does not match any of the expression, the particular code define under the default should execute.
**Conditional (Ternary) operator**
This actually operate in the same way as if else statement in a simpler version just that it is written in another way or shorter form. it involve a questions mark "?" which indicate that it is true and a semi-colon ":" for false. it reduce the amount of code and make the code more readable to comprehend when dealing with simple conditions.
```js
let samuelAge = 18
const eligibility = (samuelAge >=18) ? "you are eligible to vote" : "you are not eligible to vote"
//output: you are eligible to vote
```
Inconclusion, conditional statement is well used in javascript to determine output of our programs based on certain conditions, and it is found in most programming language. however knowing how to use if statement, if else statement, else if statement, switch statement, and ternary operator will determine our programming output and it will go a long way.

Ok, here is the last section, let's summarize what we will do here. First, we will add a start page, just for beauty; if you use _Obsidian_, then it can be integrated into _vim_, this is also on our plan today; we will add a preview of `.md` files; cli for working with _git_; a very large and cool plugin for improving the UI, which combines a buffer, an integrated terminal, navigation tips, git integration and much more; and most importantly - where would we be without AI in 2024 (⌒ω⌒)
Let's start with something simpler, preview of md files, we will not configure it, as for me it is more convenient to launch it through the vim command, but if you want you can configure it for yourself.
```lua
--init.lua
require("lazy").setup({
---
{
"iamcco/markdown-preview.nvim",
cmd = { "MarkdownPreviewToggle", "MarkdownPreview", "MarkdownPreviewStop" },
ft = { "markdown" },
build = function()
vim.fn["mkdp#util#install"]()
end,
},
---
})
```
Let's now create a start page, you can add an image in ASCII format to it, google the image to your taste, but for example I will choose this:
```lua
--init.lua
require("lazy").setup({
---
{
"goolord/alpha-nvim",
config = function()
require("alpha").setup(require("alpha.themes.dashboard").config)
end,
},
---
})
```
```lua
--alpha_config.lua
local alpha = require("alpha")

The next step is to add one very powerful tool that will improve your vim experience.
```lua

```
And let's set it up accordingly.
```lua

vim.keymap.set("n", "gr", builtin.lsp_references, opts)
end,
})
```
Now I want to clarify the situation a little, the next plugin has quite a large code, so I will not write it here, otherwise half of this article will be only for it. Therefore, I came to a consensus, I will just leave a link to this plugin and recommend that you figure it out yourself, it is not difficult, you just copy and paste the code from their manual to yourself. You can also configure it at your own discretion. I will only say that it has a buffer zone, you can improve the explorer we already have, install a git observer and many other informative things.
{% embed https://github.com/rebelot/heirline.nvim %}
As a result, you should get something like this, when I was setting it up, I broke everything down into separate components, just to make it more convenient:
Let's integrate lazygit into our config, it provides a git interface to visualize your project. But first you need to install it on your device.
{% embed https://github.com/jesseduffield/lazygit#installation %}
After installation, install the plugin:
```lua
--init.lua
require("lazy").setup({
---
{ 'kdheepak/lazygit.nvim' },
---
})
```
for quick access you can set keymap:
```lua
--keymap.lua
---
kmap.set("n", "<leader>gg", "<cmd>lazyGit<cr>")
```
The penultimate plugin will be the simplest, it will simply prompt you for key combinations, the combinations that you have written down yourself are duplicated here.
```lua
--init.lua
require("lazy").setup({
---
{
"folke/which-key.nvim",
event = "VeryLazy",
init = function()
vim.o.timeout = true
vim.o.timeoutlen = 300
end,
},
---
})
```
The configuration is appropriate:
```lua
--whichkey_config.lua
require("which-key").setup({

```
Well, the last thing I would like to do is to run our vim through neovide, but this is optional. First, you need to download it from the [official site](https://neovide.dev/), then write a small config for it in init.lua and everything is ready:
```lua
--init.lua
if vim.g.neovide then
--if you want transparency, add it
vim.g.neovide_transparency = 0.9
--Write your font and its size
vim.opt.guifont = { "JetBrainsMono Nerd Font", ":h12" }
--Fill in the remaining fields at your discretion, whatever you like best
end
```
And finally the final boss, it is not as difficult as all before, although I would even say that there is nothing to do here. And so, installing the AI, first download the AI model itself, look at how to install it on your device on the official website, in my case it is `brew install tabbyml/tabby/tabby`
Next install the plugin in _vim_:
{% embed https://tabby.tabbyml.com/ %}
```lua
--init.lua
require("lazy").setup({
---
{ "TabbyML/vim-tabby" },
---
})
```
Launch our server through this command and everything is ready:
`tabby serve --device metal --model StarCoder-1B`
Here we come to the end, in the end I will say that it turned out quite interesting, the config turned out not ideal, because there is always something that can be improved or improved. I wrote all this for the first time, I just wanted to try, and therefore criticism is welcome <(￣︶￣)>
All the best to you, dear programmers. | alekanteri |

My submission focuses on developing a custom GraphQL data fetcher for the **OPAL policy engine**, seamlessly integrated with a Neon _serverless Postgres_ database. This project not only showcases my technical skills but also contributes to the OPAL ecosystem by enhancing its data-fetching capabilities.
## Project Overview
- In this project, I created a custom data fetcher that allows OPAL to fetch data from a GraphQL API in real-time and synchronize it with the policy engine. The data fetcher is designed to be highly configurable and uses environment variables to manage connections securely. This approach simplifies the process of integrating various data sources into OPAL, facilitating dynamic policy updates based on external data.
## Key Features
1. `GraphQL Integration`:
- The fetcher connects to a GraphQL API to retrieve data needed for policy decisions. For demonstration, I used the GitHub GraphQL API, allowing the fetcher to query user information and repository details.
- The GraphQL query and endpoint are defined through environment variables, making the fetcher flexible and adaptable to different GraphQL APIs.
2. `Neon Integration`:
- The project utilizes Neon, a serverless Postgres database, to store and manage fetched data. This choice aligns with modern cloud-native practices, ensuring scalability and reliability without the overhead of managing database infrastructure.
- The connection to the Neon database is also managed via environment variables, ensuring secure and straightforward configuration.
3. `Dockerized Deployment`:
- The entire application is containerized using Docker, ensuring consistency across different development and production environments.
- A Docker Compose setup is provided to simplify the deployment process, allowing users to get the fetcher up and running quickly.

1,888,563 | Best Practices for API Testing with Playwright in a Software Development Company | Modern software development hinges on the seamless interaction between various components and... | 0 | 2024-06-14T12:50:34 | https://dev.to/jessicab/best-practices-for-api-testing-with-playwright-in-a-software-development-company-5dmk | api, apitesting, playwright, softwaredevelopment | Modern software development hinges on the seamless interaction between various components and external services. Application Programming Interfaces (APIs) serve as the communication layer facilitating this exchange. While their presence may be subtle, their role is undeniable.
Therefore, a software development company must focus on robust API testing. Now the question is, which one is appropriate for API testing?
There are many names in the software development industry, but Playwrite excels in this game. So, is Playwright good for API testing? The answer is "yes."
Keep reading the blog to discover the best practices for Playwright API testing.
## Why is API testing essential for a software development company?
Robust API testing emerges as an essential practice for a software development company in the US for several reasons:
### Functional validation
APIs reveal the capabilities that different components of an application or external systems depend on. Comprehensive testing of APIs guarantees these capabilities work as expected, following set standards and data agreements. Instruments such as Postman or Curl can issue test requests and check the results against the expected formats and structures.
### Early issue identification
Adopting a left-to-right approach in software development, which focuses on identifying problems early, is crucial. API testing allows developers to spot and fix issues within the API layer before affecting other systems. This strategy prevents the need for expensive bug fixes later in the development process.
### Better reliability and efficiency
APIs are the foundation of data sharing. API testing aids in pinpointing areas that slow down performance and ensures that responses are provided within reasonable times. Tools for load testing can replicate large numbers of requests to evaluate how APIs handle increased traffic and remain stable.
### Improved security
Cyber threats often target APIs. API testing includes security aspects, such as ensuring that authentication processes work properly and access is granted as planned. Tools for fuzzing can be used to test APIs for possible weaknesses.
## Best API testing practices with Playwright in software development
Below are the best practices to empower a software development company to conduct effective Playwright tests for APIs:
### Define the end-to-end test coverage goals
Before creating tests, it's essential to have a well-defined plan for the main features that need to be tested. Not every process requires testing from start to finish (E2E). A practical strategy focuses on the essential features necessary for running the business smoothly.
For a RESTful API, this could cover the following:
- Authenticating users and controlling their access
- Carrying out CRUD (Create, Read, Update, Delete) operations on crucial data structures
- Connecting with outside services
Analyzing user behavior using tools that show the most used API endpoints can help developers decide which parts of the code need testing most. These tools can also find less common but still important functions, like resetting passwords. Even though these processes are rarely used, their problems can upset users. Adding them to the test plan makes finding and fixing issues quicker.
After deciding on the essential tasks, developers can create a focused and thorough test plan that meets the testing requirements.
### Embrace stable selectors to locate elements
Playwright offers built-in assertion methods to validate data returned by API responses. These assertions use selectors to target specific elements within the JSON response object. Utilizing stable selectors is paramount
for maintaining reliable and non-flaky tests.
Here's an example utilizing Playwright's test and expect methods to assert the presence of a specific key within a JSON response:
```
test('GET /users/:id returns user details', async ({ request }) => {
const response = await request.get('/users/123');
const data = await response.json();
expect(data).toHaveProperty('name');
});
```
In this example, the toHaveProperty assertion method leverages a property name as a selector to target the desired element within the response object. This approach offers several advantages:
**Resilience against schema changes:** Minor schema modifications, such as property renames, won't necessarily break tests as long as the overall data structure remains similar.
**Maintainability:** Tests remain clear and focused on the validated data, increasing maintainability for a software development company.
**Flexibility:** Selectors can be chained to target nested elements within the response object.
### Keep the tests focused and isolated
Playwright fosters isolated test environments. Each test executes with its own in-memory representation of the API state. This isolation ensures that tests are unaffected by the outcomes or side effects of other tests, promoting independent and reliable test results.
To benefit from this architecture, developers should keep their tests streamlined and focused, ensuring they precisely reflect the workflow under examination. For instance, consider testing a user login functionality:
```
test('POST /login authenticates a valid user', async ({ request }) => {
const loginData = {
username: 'johndoe',
password: 'secret123',
};
const response = await request.post('/login', loginData);
expect(response.status()).toBe(200);
expect(await response.json()).toHaveProperty('token');
});
```
This test is focused solely on the login functionality. It sends a POST request with login credentials and asserts a successful response with a 200 status code and the presence of an access token within the response body.
Bundling additional functionalities, such as retrieving user details after successful login, compromises the ability to test each operation in isolation and could lead to cascading failures across the test suite.
### Craft assertions from an end-user perspective
Meaningful assertions mimic user interactions and expectations when interacting with the API. They go beyond simply verifying the presence of elements within the response. Instead, they ensure the API's behavior aligns with what users would expect.
This includes verifying:
- The presence or absence of specific data fields
- Data types and formatting of returned values
- Expected error messages for invalid requests
- Status codes indicating successful or failed operations
For example, when a user tries to set up a new account using a current email address, a meaningful assertion could check that the response contains an error message indicating the email address conflict:
```
test('POST /users creates a new user', async ({ request }) => {
const userData = {
email: 'existing@example.com',
password: 'securepassword',
};
const response = await request.post('/users', userData);
expect(response.status()).toBe(400);
expect(await response.json()).toHaveProperty('error');
```
### Utilize descriptive tests and step titles for clarity
Developers of a custom software development company in the USA often encounter a failing test after hours of refactoring. The test output resembles the following:
error: Timed out waiting for expected condition
Deciphering the issue from such output becomes a daunting task, requiring examination of test scripts to identify the root cause. Descriptive test and step titles offer a clear advantage:
```
test.describe('User Authentication', () => {
test('POST /login authenticates a valid user', async ({ request }) => {
// Test steps and assertions
});
test('POST /login returns an error for invalid credentials', async ({ request }) => {
// Test steps and assertions
});
});
```
These titles not only indicate the functionalities being tested but also the specific actions and expected outcomes. Playwright supports structuring tests with clear steps, each with its own descriptive title. This approach streamlines troubleshooting and prevents tests from becoming overloaded with unnecessary checks.
### Test across all relevant browsers
Modern web applications often interact with APIs through browser-based JavaScript code. Playwright simplifies cross-browser testing, ensuring that API integrations function flawlessly across various user environments. Projects can be established within the Playwright configuration file, specifying the browsers or devices targeted for testing.
```
const { defineConfig } = require('@playwright/test');
module.exports = defineConfig({
projects: [
{
name: 'Chromium',
use: { ...require('playwright/devices').chromium },
},
{
name: 'Firefox',
use: { ...require('playwright/devices').firefox },
},
{
name: 'Webkit',
use: { ...require('playwright/devices').webkit },
},
],
});
```
The provided code snippet showcases configurations for Chromium, Firefox, and WebKit browsers. Playwright also supports testing against branded browsers like Chrome, Safari, and Edge. It also emulates mobile and tablet viewports for comprehensive testing in a software development consulting company.
### Automate and monitor your tests
Running tests solely on a local development environment is insufficient for a robust development cycle. Integration with CI/CD pipelines is crucial for monitoring tests alongside builds. Ideally, tests should execute on every code commit and pull request. Playwright provides sample configurations for popular CI providers like GitHub Actions, Azure Pipelines, and CircleCI, facilitating seamless integration.
As the test suite grows, execution time becomes a consideration that can impact development velocity. Playwright offers parallel test execution by default, leveraging available CPU cores for faster testing. Further optimization can be achieved through test sharding, which involves splitting the test suite into multiple parts that can be executed concurrently on separate machines.
```
npx playwright test --shard=1/2
npx playwright test --shard=2/2
```
These commands illustrate sharding a test suite into two parts, enabling parallel execution on two machines. The generated reports can then be merged for consolidated test results. Many CI platforms support parallel job execution, further accelerating the testing process.
### Don't test third-party integrations directly
Web applications frequently rely on third-party APIs for functionalities like payments, social logins, or data analytics. Integrating these directly into E2E tests introduces the following challenges to a software development company:
- Unpredictable response times
- Rate limits imposed by third-party services
- Additional costs associated with excessive API calls
These factors can slow down tests and lead to intermittent failures due to network inconsistencies, hindering the test suite's reliability. To circumvent these issues, developers should avoid directly testing third-party integrations within E2E tests.
Playwright's Network API empowers developers to mock these external services. This approach involves simulating the behavior of third-party APIs, ensuring tests remain rapid and consistent regardless of the performance or availability of the real services.
```
test('POST /orders places an order', async ({ request }) => {
await request.route('/payment-gateway/process', (route) => {
route.fulfill({
status: 200,
body: '{"success": true}',
});
});
const orderData = {
items: [...],
paymentInfo: [...],
};
const response = await request.post('/orders', orderData);
expect(response.status()).toBe(201);
});
```
The provided code snippet showcases how to mock the behavior of a payment gateway API by intercepting requests directed to /payment-gateway/process. The mock response simulates a successful payment transaction, ensuring that the order placement functionality within the test remains isolated and unaffected by external dependencies.
Separate test suites can be established to compare mock data with actual API outputs for alignment verification. This approach balances the need to validate integration functionality with the requirement for rapid and reliable E2E tests.
### Leverage Playwright's tooling
Script Creator provides an all-in-one package for simplifying the process of creating, running, and fixing tests. Thus, a software development company must leverage Playwrite's tooling:
**Inspector:** This in-built inspector empowers programmers to examine and fix test scripts by pausing the program at specific points. It helps move step-by-step through the code and inspect the output from the console.
**UI mode:** UI Mode is equipped with features that simplify the process of exploring, running, and troubleshooting tests. Such a feature allows developers to move back in time within the testing process. It is a wait-and-see mode for automatically re-executing tests after code updates and a detailed record of test progress.
**Trace viewer:** This tool helps pinpoint the source of test failures by offering details about each step. It also includes images of what was displayed on the page, the information sent over the network, and how the user interacted with the system.
**Visual Studio Code add-on:** Developers can make use of the Playwright add-on for VS Code. This allows them to create, execute, and debug tests directly from their preferred coding environment.
Code creator: Playwright's command line tool enables the creation of test scripts by capturing how users interact with a page. This is especially useful in the early stages of test case development.
**TypeScript compatibility:** Playwright is designed to be compatible with TypeScript, allowing developers to create and execute tests within TypeScript files. This can enhance type safety and integrate smoothly with their current coding practices.

1,888,566 | Multifunctional IDE using Neovim (2 of 3) | Let's make it better We are done with the basic settings, now let's move on to improving... | 0 | 2024-06-14T12:50:22 | https://dev.to/alekanteri/multifunctional-ide-using-neovim-2-of-3-4off | neovim, javascript, rust, code | ### Let's make it better
We are done with the basic settings, now let's move on to improving our working environment. We will add convenient file navigation, a search engine and much more.
let's start with the explorer, everything is pretty standard here, we install the required plugin and write its configuration in a separate file.
{% embed https://github.com/nvim-tree/nvim-tree.lua %}
Adding a plugin to `init.lua`
```lua
--init.lua
require("lazy").setup({
---
{
"nvim-tree/nvim-tree.lua",
dependencies = { "nvim-tree/nvim-web-devicons" },
},
---
})
```
Create a new file `tree_config.lua` and write all of this:
```lua
--tree_config.lua
vim.g.loaded_netrw = 1
vim.g.loaded_netrwPlugin = 1
vim.opt.termguicolors = true
require("nvim-tree").setup({
sort = {
sorter = "case_sensitive",
},
view = {
width = 35,
},
renderer = {
group_empty = true,
icons = {
glyphs = {
git = {
unstaged = "",
staged = "S",
unmerged = "",
renamed = "",
untracked = "U",
deleted = "",
ignored = "◌",
},
},
},
},
git = {
enable = true,
ignore = false,
show_on_dirs = true,
show_on_open_dirs = true,
},
filters = {
dotfiles = false,
},
diagnostics = {
enable = true,
show_on_dirs = true,
icons = {
hint = "",
info = "",
warning = "",
error = "",
},
},
})
--Open Expkorer
vim.keymap.set("n", "<leader>e", "<cmd>NvimTreeToggle<cr>")
--Change focus from code to Explorer
vim.keymap.set("n", "<C-h>", "<C-w>w")
```
Now let's add a plugin for quick search of files or text in files, for this you need to install _telescope.nvim_. Everything is as always, we install via `init.lua` and create a new file.
{% embed https://github.com/nvim-telescope/telescope.nvim %}
```lua
--init.lua
require("lazy").setup({
---
{
"nvim-telescope/telescope.nvim",
--The version is entered manually, so it may differ from the latest, so enter the version from the repository
tag = "0.1.8",
dependencies = { "nvim-lua/plenary.nvim" },
},
---
})
```
And now let's set up our plugin a little. Create a file `telescope_config.lua`
```lua
---telescope_config.lua
require("telescope").setup({
defaults = {
file_ignore_patterns = {
"node_modules",
"yarn.lock"
},
dynamic_preview_title = true,
path_directory = "smart"
}
})
local builtin = require("telescope.builtin")
vim.keymap.set("n", "<leader>ff", builtin.find_files, {})
vim.keymap.set("n", "<leader>fb", builtin.buffers, {})
vim.keymap.set("n", "<leader>fh", builtin.help_tags, {})
vim.keymap.set("n", "<leader>fr", builtin.oldfiles, {})
```
Now let's add auto-completion to our config. For this we will use _nvim-cmp_ install it in the way we are already familiar with.
{% embed https://github.com/hrsh7th/nvim-cmp %}
```lua
--init.lua
require("lazy").setup({
---
{ "hrsh7th/cmp-nvim-lsp" },
{ "hrsh7th/cmp-buffer" },
{ "hrsh7th/cmp-path" },
{ "hrsh7th/cmp-cmdline" },
{ "hrsh7th/nvim-cmp" },
{ "hrsh7th/cmp-vsnip" },
{ "hrsh7th/vim-vsnip" },
{ "L3MON4D3/LuaSnip" },
{ "saadparwaiz1/cmp_luasnip" },
---
})
```
Create a new file `cmp_config.lua`
```lua
--cmp_config.lua
local cmp = require('cmp')
local kind_icons = {
Text = "",
Method = "",
Function = "",
Constructor = "",
Field = "",
Variable = "",
Class = "",
Interface = "",
Module = "",
Property = "",
Unit = "",
Value = "",
Enum = "",
Keyword = "",
Snippet = "",
Color = "",
File = "",
Reference = "",
Folder = "",
EnumMember = "",
Constant = "",
Struct = "",
Event = "",
Operator = "",
TypeParameter = "",
}
cmp.setup({
formatting = {
format = function(entry, vim_item)
vim_item.kind = string.format('%s %s', kind_icons[vim_item.kind], vim_item.kind)
vim_item.menu = ({
buffer = "[Buffer]",
nvim_lsp = "[LSP]",
luasnip = "[LuaSnip]",
nvim_lua = "[Lua]",
latex_symbols = "[LaTeX]",
})[entry.source.name]
return vim_item
end
},
snippet = {
expand = function(args)
vim.fn["vsnip#anonymous"](args.body)
end,
},
mapping = cmp.mapping.preset.insert({
['<C-b>'] = cmp.mapping.scroll_docs(-4),
['<C-f>'] = cmp.mapping.scroll_docs(4),
['<C-Space>'] = cmp.mapping.complete(),
['<C-e>'] = cmp.mapping.abort(),
['<CR>'] = cmp.mapping.confirm({ select = true }),
}),
sources = cmp.config.sources({
{ name = 'nvim_lsp' },
{ name = 'luasnip' },
}, {
{ name = 'buffer' },
})
})
cmp.setup.filetype('gitcommit', {
sources = cmp.config.sources({
{ name = 'git' },
}, {
{ name = 'buffer' },
})
})
cmp.setup.cmdline({ '/', '?' }, {
mapping = cmp.mapping.preset.cmdline(),
sources = {
{ name = 'buffer' }
}
})
cmp.setup.cmdline(':', {
mapping = cmp.mapping.preset.cmdline(),
sources = cmp.config.sources({
{ name = 'path' }
}, {
{ name = 'cmdline' }
})
})
```
Well, let's quickly write a config for treesitter. _Nvim-treesitter_ is based on three interlocking features: language parsers, queries, and modules, where modules provide features – e.g., highlighting.
{% embed https://github.com/nvim-treesitter/nvim-treesitter %}
To install, add it to `lazy.nvim`
```lua
require("lazy").setup({
---
{ "nvim-treesitter/nvim-treesitter" },
---
})
```
And as always, we write the configuration in a separate file:
```lua
--treesitter_config.lua
require 'nvim-treesitter.configs'.setup {
-- A list of parser names, or "all" (the five listed parsers should always be installed)
ensure_installed = { "lua", "vim", "vimdoc", "query", "javascript", "typescript", "html", "css", "rust", "markdown", "json" },
sync_install = false,
auto_install = true,
highlight = {
enable = true,
additional_vim_regex_highlighting = false,
},
autotag = {
enable = true,
}
}
vim.opt.foldmethod = "expr"
vim.opt.foldexpr = "nvim_treesitter#foldexpr()"
vim.opt.foldenable = false
```
There is a small plugin that allows you to link brackets by color, let's add it.
```lua
require("lazy").setup({
---
{ "lukas-reineke/indent-blankline.nvim", main = "ibl", opts = {} },
---
})
```
Create a new file `indent_config.lua`:
> If you don't like the colorful theme, you can make the configuration more down to earth, but I like when the brackets are different colors.
```lua
--indent_config.lua
local highlight = {
"RainbowRed",
"RainbowYellow",
"RainbowBlue",
"RainbowOrange",
"RainbowGreen",
"RainbowViolet",
"RainbowCyan",
}
local hooks = require "ibl.hooks"
hooks.register(hooks.type.HIGHLIGHT_SETUP, function()
vim.api.nvim_set_hl(0, "RainbowRed", { fg = "#E06C75" })
vim.api.nvim_set_hl(0, "RainbowYellow", { fg = "#E5C07B" })
vim.api.nvim_set_hl(0, "RainbowBlue", { fg = "#61AFEF" })
vim.api.nvim_set_hl(0, "RainbowOrange", { fg = "#D19A66" })
vim.api.nvim_set_hl(0, "RainbowGreen", { fg = "#98C379" })
vim.api.nvim_set_hl(0, "RainbowViolet", { fg = "#C678DD" })
vim.api.nvim_set_hl(0, "RainbowCyan", { fg = "#56B6C2" })
end)
require("ibl").setup { indent = { highlight = highlight } }
```
Let's add two small plugins to improve your comments in code right away. The first plugin allows you to quickly comment one or more lines with one key. The second plugin allows you to expand comments, leaving notes like in a to-do list.
```lua
--init.lua
require("lazy").setup({
---
{
"numToStr/Comment.nvim",
lazy = false,
},
{
"folke/todo-comments.nvim",
dependencies = { "nvim-lua/plenary.nvim" },
},
---
})
```
And configure each of them in their own file, although for the comment switcher this is not really necessary, you can just call it in our `init.lua` file, but I'd rather separate it into a separate file.
```lua
--comment_config.lua
require('Comment').setup()
```
```lua
--todo_config.lua
require("todo-comments").setup({
signs = true,
sign_priority = 8,
keywords = {
FIX = {
icon = " ",
color = "error",
alt = { "FIXME", "BUG", "FIXIT", "ISSUE" },
},
TODO = { icon = " ", color = "info" },
HACK = { icon = " ", color = "warning" },
WARN = { icon = " ", color = "warning", alt = { "WARNING", "XXX" } },
PERF = { icon = " ", alt = { "OPTIM", "PERFORMANCE", "OPTIMIZE" } },
NOTE = { icon = " ", color = "hint", alt = { "INFO" } },
TEST = { icon = "⏲ ", color = "test", alt = { "TESTING", "PASSED", "FAILED" } },
},
gui_style = {
fg = "NONE",
bg = "BOLD",
},
merge_keywords = true,
highlight = {
multiline = true,
multiline_pattern = "^.",
multiline_context = 10,
before = "",
keyword = "wide",
after = "fg",
pattern = [[.*<(KEYWORDS)\s*:]],
comments_only = true,
max_line_len = 400,
exclude = {},
},
colors = {
error = { "DiagnosticError", "ErrorMsg", "#DC2626" },
warning = { "DiagnosticWarn", "WarningMsg", "#FBBF24" },
info = { "DiagnosticInfo", "#2563EB" },
hint = { "DiagnosticHint", "#10B981" },
default = { "Identifier", "#7C3AED" },
test = { "Identifier", "#FF00FF" }
},
search = {
command = "rg",
args = {
"--color=never",
"--no-heading",
"--with-filename",
"--line-number",
"--column",
},
-- regex that will be used to match keywords.
-- don't replace the (KEYWORDS) placeholder
pattern = [[\b(KEYWORDS):]], -- ripgrep regex
-- pattern = [[\b(KEYWORDS)\b]], -- match without the extra colon. You'll likely get false positives
},
})
vim.keymap.set("n", "]t", function()
require("todo-comments").jump_next()
end, { desc = "Next todo comment" })
vim.keymap.set("n", "[t", function()
require("todo-comments").jump_prev()
end, { desc = "Previous todo comment" })
--to search by comments
vim.keymap.set("n", "<leader>ft", "<cmd>TodoTelescope<cr>")
```
for css I use _colorizer_ to immediately see what color palette I applied to a given class, installation and configuration is simple
```lua
--init.lua
require("lazy").setup({
---
{ "norcalli/nvim-colorizer.lua" },
---
})
```
```lua
--conlorizer_config.lua
require("colorizer").setup({
"*",
}, {
names = true,
rgb_fn = true,
RGB = true,
RRGGBB = true,
RRGGBBAA = true,
hsl_fn = true,
css = true,
css_fn = true,
mode = "background",
})
```
Now our vim looks much better, but it's not over yet, there's the last section left, in it we will integrate separate cli inside our vim, further improve the UI and add many new features | alekanteri |

If you haven't read it yet, **go check it out**. It provides context for this post.
It's been over 18 months, and things move fast in JS land. I decided to revisit the code, update Remix itself, leverage [Vite's Environment Variables](https://vitejs.dev/guide/env-and-mode), and use [my new friend](https://dev.to/seasonedcc/using-arktype-in-place-of-zod-how-to-adapt-parsers-3bd5) - [ArkType](https://github.com/arktypeio/arktype) - to parse the environment variables this time.
> If you only want to see the code, check out the [updates' diff here](https://github.com/gustavoguichard/remix-public-env/pull/1).
## The Gist of Changes
By updating Remix from 1.7 to 2.9 and using [Vite](https://vitejs.dev) we can now use `import.meta.env` so we don't need to manually load the environment variables and expose them to the window anymore. That update reduces a lot of shenanigans from the previous approach.
I'm also switching from [Zod](https://github.com/colinhacks/zod) to [ArkType](https://github.com/arktypeio/arktype), introducing a `makeTypedEnvironment` helper to streamline handling environment variables in both server and client environments. Additionally, there are a few optimizations I'll be pointing out through the post.
## The New `makeTypedEnvironment` Helper
This helper is designed to work seamlessly in both server and client environments, making it a versatile tool. It can handle different parsers, avoid mutating the original objects, and transform environment variable keys to `camelCase`.
Let's first start by making it work in multiple environments.
```ts
// lib/index.ts
// This function creates a typed environment by accepting a Zod schema parser.
function makeTypedEnvironment<T>(schema: { parse: (v: unknown) => T }) {
// The returned function applies the schema parser to the provided environment variables.
return (args: Record<string, unknown>): T => schema(args)
}
```
We can use it in both server or client:
```ts
import { z } from 'zod'
import { makeTypedEnvironment } from '~/lib'
// Define the environment Zod schema.
const envSchema = z.object({
MODE: z.enum(['development', 'test', 'production']).default('development'),
})
// Create the environment parser using the makeTypedEnvironment helper.
const getEnv = makeTypedEnvironment(envSchema)
// Server usage: parse environment variables from process.env
const env = getEnv(process.env)
// ^? { MODE: 'development' }
// Vite client-side env vars usage: parse environment variables from import.meta.env
const env = getEnv(import.meta.env)
// ^? { MODE: 'development' }
```
> You could also use `getEnv(window.ENV)` if you are not using Vite, just follow the instructions on the [previous post](https://dev.to/seasonedcc/type-safe-environment-variables-on-both-client-and-server-with-remix-54l5).
### Accepting Different Parsers and Preventing Mutations
To use it with ArkType, I'll make it accept a more generic parser as an argument.
```ts
// Function to create a typed environment that accepts a generic parser.
function makeTypedEnvironment<T>(schema: (v: unknown) => T) {
// Spread the arguments to clone them, avoiding mutations to the original object.
return (args: Record<string, unknown>): T => schema({ ...args })
}
```
The `args` was cloned above to avoid mutations. Some parsers, like ArkType, mutate the object (🥲) passed to them. This way, we ensure the original object is not changed.
Now we can use that function with both Zod and ArkType.
```ts
import { z } from 'zod'
import { type } from 'arktype'
import { makeTypedEnvironment } from '~/lib'
// Define the environment schema using Zod.
const envZodSchema = z.object({
MODE: z.enum(['development', 'test', 'production']).default('development'),
})
// Create the environment parser for Zod.
const getZodEnv = makeTypedEnvironment(envZodSchema.parse)
// Define the environment schema using ArkType.
const envArkSchema = type({
MODE: ['"development"|"test"|"production"', '=', 'development'],
})
// Create the environment parser for ArkType.
const getArkEnv = makeTypedEnvironment((d) => envArkSchema.assert(d))
```
Perfect!
### Transforming the Env Vars to `camelCase`
For convenience, I'll use `string-ts` to transform the env vars to `camelCase`, making the usage feel more like JS code..
```ts
import { camelKeys } from 'string-ts'
// Function to create a typed environment with camelCase transformation.
function makeTypedEnvironment<T>(schema: (v: unknown) => T) {
// Apply camelCase transformation to the parsed environment variables.
return (args: Record<string, unknown>) => camelKeys(schema({ ...args }))
}
```
Now let's use the original public schema from the previous post and see how it looks like:
```ts
// environment.server.ts
import { type } from 'arktype'
import { makeTypedEnvironment } from '~/lib'
// Define the environment schema using ArkType.
const publicEnvSchema = type({
// We prefix the keys with VITE_ to expose them in the client bundle.
VITE_GOOGLE_MAPS_API_KEY: 'string',
VITE_STRIPE_PUBLIC_KEY: 'string',
})
// Create the environment parser with camelCase transformation.
const getEnv = makeTypedEnvironment((d) => envSchema.assert(d))
// Parse environment variables from process.env
const env = getEnv(process.env)
// ^? { viteGoogleMapsApiKey: string, viteStripePublicKey: string }
```
By leveraging `string-ts`, I’ve transformed the environment variable keys to `camelCase`, making them more intuitive to use in JavaScript code. This transformation is applied at both type and runtime levels.
### Getting rid of the `VITE_` prefix
You may have noticed we are adding the `VITE_` prefix to those variables that we want to be exposed to the client bundle through Vite's `import.meta.env` object. That comes from the [Vite API](https://vitejs.dev/guide/env-and-mode#env-files) and you can [change the prefix](https://vitejs.dev/config/shared-options.html#envprefix) if you want.
We can go further and remove that prefix as follows:
```ts
import { camelKeys, replaceKeys } from 'string-ts'
function makeTypedEnvironment<T>(schema: (v: unknown) => T) {
// Apply replaceKeys before camelCase transformation to the parsed environment variables.
return (args: Record<string, unknown>) =>
camelKeys(replaceKeys(schema({ ...args }), 'VITE_', ''))
}
```
Check out the result:
```ts
// environment.server.ts
import { type } from 'arktype'
import { makeTypedEnvironment } from '~/lib'
// Define the environment schema using ArkType.
const publicEnvSchema = type({
VITE_GOOGLE_MAPS_API_KEY: 'string',
VITE_STRIPE_PUBLIC_KEY: 'string',
})
// Create the environment parser with camelCase transformation.
const getEnv = makeTypedEnvironment((d) => envSchema.assert(d))
// Parse environment variables from process.env
const env = getEnv(process.env)
// ^? { googleMapsApiKey: string, stripePublicKey: string }
```
Much better!
### Last Optimization: Caching
To enhance performance, I’ve implemented caching in the `makeTypedEnvironment` function. This prevents the schema from being reparsed every time the environment variables are accessed, resulting in faster and more efficient code execution.
This change was inspired by [a comment from the first post](https://dev.to/creeefs/comment/25icc).
```ts
import type { CamelKeys, ReplaceKeys } from 'string-ts'
import { camelKeys, replaceKeys } from 'string-ts'
// Function to create a typed environment with caching.
function makeTypedEnvironment<T>(schema: (v: unknown) => T) {
// Instantiate a cache to store parsed environment variables.
let cache: CamelKeys<ReplaceKeys<T, 'VITE_', ''>>
return (args: Record<string, unknown>) => {
// If the environment variables are already cached, return the cached value.
if (cache) return cache
// Otherwise, parse the environment variables and transform the keys
const withoutPrefix = replaceKeys(schema({ ...args }), 'VITE_', '')
const camelCased = camelKeys(withoutPrefix)
cache = camelCased
return cache
}
}
```
You can add `console.log` around to see the cache in action.
## Extending Schemas
We can leverage ArkType’s ability to extend schemas, simplifying the process of creating a superset of the public schema.
```ts
// environment.ts
import { type } from 'arktype'
// Define the public environment schema.
const publicEnvSchema = type({
VITE_GOOGLE_MAPS_API_KEY: 'string',
VITE_STRIPE_PUBLIC_KEY: 'string',
})
// Extend the public schema to create the full environment schema.
const envSchema = type(publicEnvSchema, '&', {
MODE: ["'development'|'production'|'test'", '=', 'development'],
SESSION_SECRET: 'string',
STRIPE_SECRET_KEY: 'string',
})
// Create the environment parsers for public and full schemas.
const getPublicEnv = makeTypedEnvironment((d) =>
publicEnvSchema.onUndeclaredKey('delete').assert(d)
)
const getEnv = makeTypedEnvironment((d) => envSchema.assert(d))
```
This approach can also be done using Zod's `.extend` method for comparison.
```ts
import { z } from 'zod'
// Define the public environment schema.
const publicEnvSchema = z.object({
VITE_GOOGLE_MAPS_API_KEY: z.string(),
VITE_STRIPE_PUBLIC_KEY: z.string(),
})
// Extend the public schema to create the full environment schema.
const envSchema = publicEnvSchema.extend({
MODE: z.enum(['development', 'production', 'test']).default('development'),
SESSION_SECRET: z.string(),
STRIPE_SECRET_KEY: z.string(),
})
// Create the environment parsers for public and full schemas.
const getPublicEnv = makeTypedEnvironment(
publicEnvSchema.onUndeclaredKey('delete').parse,
)
const getEnv = makeTypedEnvironment(envSchema.parse)
```
We are using ArkType's `.onUndeclaredKey('delete')` to remove undeclared keys from the object so we avoid exposing secrets to the client.
> ArkType's default strategy is called _Loose Assertion_ while Zod will omit undeclared keys by default - _Safe Parsing_.
## Et Voilà
Thanks to Vite, we can go ahead and [remove a bunch of code](https://github.com/gustavoguichard/remix-public-env/pull/1/files) from the previous post.
Now, anywhere in your code, you can access the public environment variables in a type-safe way:
```tsx
// app/routes/index.tsx
import { getPublicEnv } from '~/environment'
export default function Index() {
function showStripeKey() {
alert(
`Stripe key on the client: ${
getPublicEnv(import.meta.env).stripePublicKey
}`,
)
}
return (
<div>
<h1>
GMAPS key on the server and client:{' '}
{getPublicEnv(import.meta.env).googleMapsApiKey}
</h1>
<p>
<button onClick={showStripeKey}>Alert Stripe key</button>
</p>
</div>
)
}
```
## That's It
Now we have a faster, solid, type-safe environment variable system that works on both the client and server environments. And with a great DX:
Another benefit of this approach is that you don't need to keep an `.env.sample` file as you can always check the `environment.ts` file to know what environment variables are required.
We also learned how to create functions that accept different parsers, which is a good practice, especially for library authors.
I'd love to hear your thoughts on this. If you have any questions or suggestions, please leave a comment below.

1,888,565 | Multifunctional IDE using Neovim (1 of 3) | Introduction Hello everyone, my dear programmers, today we will step by step make from the... | 0 | 2024-06-14T12:49:29 | https://dev.to/alekanteri/multifunctional-ide-using-neovim-1-of-3-3a8g | neovim, javascript, rust, code | ## Introduction
Hello everyone, my dear programmers, today we will step by step make from the standard vim, a full-fledged tool capable of replacing VSCode if desired.
I often hear this question from my friends. Why not use a ready-made config like _LazyVim_ or _NVChad_? Well, firstly, I am the kind of person who likes to have control over all aspects of what I use. Secondly, when you say that you made your own config from scratch - it sounds cooler than just installing a couple of plugins (─‿‿─).
Can this replace _VSCode_? Maybe, as for me Vim is more convenient and faster to use than VSCode, but then again sometimes I also use _VSCode_, for some specific cases.
If you have any questions about the code, you can use [my repository](https://github.com/Alekanteri/dot-files-mac) as a reference.
## Configuration
First, you need to prepare your working environment (terminal) for correct work with vim. Preparation consists in the fact that you need to install fonts for displaying icons. Using [Nerd Fonts](https://www.nerdfonts.com/#home) download the fonts that you like best, but I recommend _JetBrainsMono_, I tried _Hack_, but it did not have all the icons, which is why I did not use it. Set the font in your terminal settings.
Next, install [NeoVim](https://neovim.io/) itself on your device via the official website, or if you have _homebrew_, you can install it via the appropriate command `brew install neovim`, _Linux_ users have their own package managers for installing packages, but I will not list them :)
And now we go to _.config_ directory and create here the new _nvim_ folder, this is where we will write all our code.
### Basic setup
And finally we can start writing the configuration, create the `init.lua` file in the _nvim_ folder. For convenience, we will split our config into different modules, but ultimately all modules will be imported into the `init.lua` file. For example, let's create a new file `default.lua`, in order for lua to recognize this file as a module we must create it in a folder called _lua_, otherwise it will not be visible to the main file when imported.
```
├── init.lua
└── lua
└── default.lua
```
In this file we will write some basic commands:
```lua
--default.lua
vim.opt.number = true
vim.opt.relativenumber = true
vim.opt.scrolloff = 5
vim.opt.sidescrolloff = 5
vim.opt.hlsearch = true
vim.opt.incsearch = true
vim.opt.tabstop = 2
vim.opt.shiftwidth = 2
vim.opt.expandtab = true
vim.opt.autoindent = true
vim.opt.ignorecase = true
vim.opt.smartcase = true
vim.opt.swapfile = true
vim.opt.autoread = true
vim.opt.cursorline = true
vim.opt.termguicolors = true
vim.bo.autoread = true
vim.opt.clipboard = "unnamedplus"
vim.api.nvim_create_autocmd("TextYankPost", {
callback = function()
vim.highlight.on_yank({
higroup = "incSearch",
timeout = 100,
})
end,
})
```
To import this file we write this in init.lua:
```lua
--init.lua
require("default")
-- in the future I will not show that I import this or that file into init.lua, just know that if I write that a new file is created, then in most cases it will be imported into init.lua
```
Ok, let's go back to our `init.lua`, and install our first plugin, or rather the _lazy.nvim_ plugin manager, through it we will install all our plugins in the future.
{% embed https://github.com/folke/lazy.nvim %}
to install it you need to write the following piece of code:
```lua
--init.lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
vim.fn.system({
"git",
"clone",
"--filter=blob:none",
"https://github.com/folke/lazy.nvim.git",
"--branch=stable",
lazypath,
})
end
vim.opt.rtp:prepend(lazypath)
```
For further installation of plugins, we add a structure from the plugin manager and inside it we will add new plugins:
```lua
--init.lua
require("lazy").setup({})
```
For example, let's set a color scheme, I like [TokyoNight](https://github.com/folke/tokyonight.nvim), you can set any you like:
```lua
--init.lua
require("lazy").setup({
---
{
"folke/tokyonight.nvim",
lazy = false,
priority = 1000,
opts = {
style = "night",
styles = {
comments = { italic = true },
},
},
},
---
})
-- to apply the color scheme we write this
vim.cmd([[colorscheme tokyonight]])
```
Restart our _nvim_ and all done! <(￣︶￣)>
In _neovim_ you can set your own keymap, create a new file `keymap.lua`, my standard layout looks like this:
```lua
--keymap.lua
local kmap = vim.keymap
vim.g.mapleader = " "
kmap.set("n", "<leader>q", "<cmd>q<cr>")
kmap.set("n", "<leader>w", "<cmd>w<cr>")
kmap.set("i", "jk", "<esc>")
kmap.set("n", "<leader>h", "<cmd>noh<cr>")
```
The next step is to install and configure the _Mason_ package manager, it allows you to easily manage external editor tooling such as LSP servers, DAP servers, linters, and formatters through a single interface.
{% embed https://github.com/williamboman/mason.nvim %}
first of all, let's install it:
```lua
--init.lua
require("lazy").setup({
---
{ "williamboman/mason.nvim" },
{ "williamboman/mason-lspconfig.nvim" },
{ "neovim/nvim-lspconfig" },
{ "WhoIsSethDaniel/mason-tool-installer.nvim" },
---
})
```
Restart our `nvim` and it should install normally. Now let's write the configuration of the package manager itself. Create a new file `mason_config.lua` and here we write this:
```lua
---mason_config.lua
require("mason").setup({
ui = {
icons = {
package_installed = "✓",
package_pending = "➜",
package_uninstalled = "✗",
},
},
})
require("mason-lspconfig").setup()
```
Okay, now let's set up our first language server, here you choose for which language you need to install a server, for example, I need servers for _html_, _css_, _typescript_, _rust_, _tailwind_ and _lua_, in addition I will install _emmet_ for faster work with html.
How do you find the configuration for your language? This package manager has a [List with all supported language servers](https://github.com/williamboman/mason-lspconfig.nvim/blob/main/doc/server-mapping.md), look for the language you need there, in nvim through the command `:Mason` look for the package name as in the table, and install, then in the next column open the link to the language server, and take the configuration from there. Let's install the language server for all languages that i use as an example
> For language servers sometimes you need to install additional plugins, for example, for _rust_ you need to install _rustaceanvim_, or for _TS_ - _typescript-tools_, and additionally a linter, so if you need to work with these languages, here are these plugins, for other languages look in the repository link to which is above
```lua
--init.lua
require("lazy").setup({
---
{
"mrcjkb/rustaceanvim",
version = "^4", -- Recommended
ft = { "rust" },
},
{
"pmizio/typescript-tools.nvim",
dependencies = { "nvim-lua/plenary.nvim", "neovim/nvim-lspconfig" },
},
{
"mfussenegger/nvim-lint",
linters_by_ft = {
javascript = { "eslint_d" },
javascriptreact = { "eslint_d" },
typescript = { "eslint_d" },
typescriptreact = { "eslint_d" },
},
},
---
})
```
```lua
---mason_config.lua
---
require("mason-lspconfig").setup_handlers({
function(server_name)
require("lspconfig")[server_name].setup({})
end,
["rust_analyzer"] = function()
require("rustaceanvim").setup({})
end,
["tailwindcss"] = function()
require("lspconfig").tailwindcss.setup({})
end,
["tsserver"] = function()
require("typescript-tools").setup({})
vim.keymap.set("n", "<leader>to", "<cmd>TSToolsOrganizeImports<cr>")
vim.keymap.set("n", "<leader>tr", "<cmd>TSToolsRemoveUnusedImports<cr>")
vim.keymap.set("n", "<leader>ta", "<cmd>TSToolsFixAll<cr>")
local api = require("typescript-tools.api")
require("typescript-tools").setup({
handlers = {
["textDocument/publishDiagnostics"] = api.filter_diagnostics({ 6133 }),
},
})
end,
["html"] = function()
local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities.textDocument.completion.completionItem.snippetSupport = true
require("lspconfig").html.setup({
capabilities = capabilities,
})
end,
["emmet_ls"] = function()
require("lspconfig").emmet_ls.setup({})
end,
["cssls"] = function()
local capabilities = vim.lsp.protocol.make_client_capabilities()
capabilities.textDocument.completion.completionItem.snippetSupport = true
require("lspconfig").cssls.setup({
capabilities = capabilities,
})
end,
["lua_ls"] = function()
require("lspconfig").lua_ls.setup({
on_init = function(client)
local path = client.workspace_folders[1].name
if not vim.loop.fs_stat(path .. "/.luarc.json") and not vim.loop.fs_stat(path .. "/.luarc.jsonc") then
client.config.settings = vim.tbl_deep_extend("force", client.config.settings, {
Lua = {
diagnostics = {
globals = { "vim" },
},
runtime = {
version = "LuaJIT",
},
workspace = {
checkThirdParty = false,
library = {
vim.env.VIMRUNTIME,
},
},
},
})
end
return true
end,
})
end,
})
```
The first language server is ready, congratulations. Let's now add formatting to our code so that it looks more structured. To do this, install it via _lazy.nvim_ and immediately write its config in a separate file `formatter.lua`
```lua
--init.lua
require("lazy").setup({
---
{"stevearc/conform.nvim",},
---
})
```
Now we write its configuration, for this we need to install the corresponding formatters via _Mason_, for example _prettier_ for _JS/TS_ or _stylua_ for _lua_. Some language servers have ready-made formatters, for example _rust_analyzer_, so there is no need to configure code formatting for them. In our case, we need to install _stylua_ for lua, which is what we are doing.
```lua
--formatter.lua
require("conform").setup({
formatters_by_ft = {
lua = { "stylua" },
},
format_on_save = {
timeout_ms = 500,
lsp_fallback = true,
},
})
```
Lastly for this chapter, let's set up autopairs so that when you type an opening parenthesis, a closing parenthesis is automatically created.
```lua
--init.lua
require("lazy").setup({
---
{
"windwp/nvim-autopairs",
event = "InsertEnter",
config = true,
},
---
})
```
There is no need to configure anything here, everything works out of the box. | alekanteri |

How many times... | 0 | 2024-06-14T12:47:22 | https://www.beyonddone.com/blog/posts/how-to-find-your-forgotten-tasks | productivity, softwareengineering, career, agile | Do you ever wonder how many software engineering tasks have fallen through the cracks? How many times you've let your coworkers down?
It is extremely easy for this to happen, especially for mentions of your username scattered across various platforms like GitHub, Jira, Google Docs, Slack, and so many others. Each of these mentions represents a time when a coworker asked a question or shared a perspective squarely in your direction. If you like, or at the very least respect your coworkers, these mentions warrant some sort of response, either an emoji reaction or a comment.
Some other software engineering tasks that are easy to lose sight of:
- Jira tickets assigned, especially if they are carryovers from the previous sprint and weren't moved over to the current sprint.
- GitHub issues and pull requests you've opened for third-party libraries. These issues sometimes take months to be addressed, but it is worthwhile to keep tabs on them so you can help push them along.
- GitHub review requests.
- Other requests not captured by a Jira ticket.
## The solution
BeyondDone has a tool called the [Forgotten Task Finder](https://www.beyonddone.com/forgotten-task-finder).
This tool will guide you through connecting your GitHub and optionally your Jira account.
After connecting your accounts you'll see a summary of the findings. It even calculates the depth of disappointment you have created in your coworkers. After running through this tool, I learned I created 3 shot glasses full of coworker tears from ignoring their mentions, calculated assuming 0.5 ml tears, a crying rate of 15 ml/minute, and an average of 2 minutes of crying per forgotten mentions. Perhaps a little dramatic, but it drove the point home for me. Even if my coworkers aren't crying, I'm certainly making them feel unimportant by not addressing the comments they've directed at me.
After the summary, you'll see a full log of your regrets, including every unaddressed mention, as well as any open GitHub prs, GitHub issues, Jira tickets, and other tasks across your GitHub and Jira accounts.
## Demo
{% embed https://www.youtube.com/watch?v=fHShdj8uN00 %}
## Conclusion
The BeyondDone [Forgotten Task Finder](https://www.beyonddone.com/forgotten-task-finder) is an excellent tool to use to see all the software engineering tasks that have fallen through the cracks.
If you want to use this tool regularly, you'll need to reconnect your GitHub and Jira accounts over and over.
Thankfully, BeyondDone allows users to sign up for accounts. After signing up for an account, you only need to connect your GitHub and Jira accounts once. You'll then get access to a Todos list that gets updated with the latest information every minute. You'll also get access to automatically generated standup updates, a log of your activities, and the ability to add custom todos/accomplishments that exist outside of the GitHub, Jira, and Confluence platforms.
I use BeyondDone every day and it has turbocharged my ability to stay on top of things and sell myself better in standup.
I encourage you all to take a look at [BeyondDone's features](https://www.beyonddone.com) and [sign up today](https://www.beyonddone.com/auth/signup). There's a 30-day free trial and no payment information is required up-front.

1,888,555 | 5 Unique Features that Put Goleko Ahead of the Game | Project management platforms are requisite tools when it comes to structuring and assigning tasks,... | 0 | 2024-06-14T12:45:05 | https://dev.to/odhiambo_ouko/5-unique-features-that-put-goleko-ahead-of-the-game-3o0d | productivity, productmanagement, programming, discuss | Project management platforms are requisite tools when it comes to structuring and assigning tasks, promoting collaborations, sharing files, and, of course, boosting productivity. The need for project management solutions is even higher today, given the increasing number of remote and distributed teams around the world. While there are many project management tools to select from, one that stands out is Goleko – an up-and-coming solution with immense capabilities.
Let’s dive into a few features that make Goleko give other project management tools a run for their money.
##Automatic Smartboard
One of Goleko’s intriguing features is its cutting-edge smartboard, which delivers easy viewing and flexibility. Thanks to its compelling UI design and one-click functionality, the smartboard allows users to move seamlessly from one part of the platform to another, whether you want to assign tasks, check tasks in progress, or locate important files. These smartboard attributes enhance user experience and retention – ultimately improving productivity.
##Time-Tracking Capability
Not all project management tools have time trackers. Fortunately, Goleko has a time-tracking feature to take project management to the next level. With Goleko’s time-tracking capability, project managers and team members can check how much time was spent completing a project or the time left until specific tasks reach their deadline. As a project manager, you can use the tracking feature to not only evaluate your team members’ effectiveness but also export time logs for invoices.
##Permission Granting
Geleko has a permission feature that lets you dictate how other people interact with your projects. You can use the feature to allow select team members to create, edit, or upload a task. The feature also lets you show or hide comments and display potential price quotes to particular clients. Besides promoting collaboration, the permission-granting capability gives managers complete control of their projects for improved management and outcomes.
##Screen Recording
Another unique feature Goleko has is a screencast for recording screen videos. By recording your screen, you can explain how to do specific tasks, comment on projects, and provide real-time feedback to your team members. Since videos are easier to follow and understand than written comments and feedback, Goleko’s screen recording feature expedites communication and helps improve project success.
##Files Importation
While working on projects, you may sometimes need to use files on other tools on your computer. Goleko was made with this issue in mind, which is why it has an import feature that enables you to extract tasks and projects. The import feature is essential for quickly and efficiently transferring all your work to Goleko for centralized management.
##Leverage the Power of Goleko
[Goleko](https://goleko.com/) has several trailblazing features that make it the go-to project management tool. From its one-click smartboard to file importation capabilities, Goleko is designed to make project management easy and fun. Goleko is available in three packages – including a [Free starter pack](https://goleko.com/app) that has a total capacity of 300 megabytes and accommodates up to 3 users, 3 projects, and 300 tasks.

In the last year, I have met about 250 customers, most of them in person, and I have learned a few things about LLMs, data, and risk management in the enterprise world.
Yesterday, my AWS buddies [**Giuseppe Battista**](https://www.linkedin.com/feed/#) and [**Nicolas DAVID**](https://www.linkedin.com/feed/#) allowed me to discuss these topics and more, and I extracted the best parts into five short videos.
There is no theory here, just real-life learnings from the enterprise LLM trenches 😀

1,888,556 | What is Microservices Architecture? Examples, Challenges, Benefits and Best Practices | Microservices architecture is a software development approach that structures an application as a... | 0 | 2024-06-14T12:38:01 | https://dev.to/hyscaler/what-is-microservices-architecture-examples-challenges-benefits-and-best-practices-10be | Microservices architecture is a software development approach that structures an application as a collection of loosely coupled services, which can be developed, deployed, and scaled independently. It contrasts with the traditional monolithic architecture, where the entire application is built as a single unit.
## Examples of Microservices Architecture
* *Real-world case studies*: Companies like Netflix, Amazon, and Uber have successfully implemented microservices architecture to improve scalability and development efficiency.
* *Successful microservices implementations*: Airbnb's migration to microservices enabled them to innovate quickly and scale their platform.
* *Diverse industry applications*: Microservices are utilized in various sectors such as finance, healthcare, and e-commerce to adapt to rapidly changing business needs.
## Core Traits of Microservices
### Modularity and independent deployment
Microservices are designed to be modular, allowing teams to work on different services independently without affecting others.
### Loose coupling between services
Services communicate through APIs, promoting a high degree of independence and flexibility.
### Polyglot programming and data management
Different services can be built using diverse [programming languages](https://hyscaler.com/insights/a-guide-to-top-20-coding-languages-list/) and databases to optimize performance.
### Decentralized governance and ownership
Teams are responsible for the full lifecycle of their services, enhancing ownership and accountability.
## Benefits of Microservices Architecture
* *Scalability and flexibility*: Microservices can be scaled horizontally to handle increased traffic and adapt to changing business requirements.
* *Faster development and deployment*: Teams can iterate quickly on services, leading to faster time-to-market.
* *Improved fault tolerance and resilience*: Isolating failures to individual services improves overall system reliability.
* *Better technology flexibility and innovation*: Microservices allow the adoption of new technologies without impacting the entire system.
## Challenges and Considerations
### Complexity of distributed systems
Managing a network of services introduces complexities regarding monitoring, debugging, and ensuring system consistency.
### Communication and integration between services
Effective communication protocols are essential to maintain data consistency and avoid service dependencies.
### Monitoring and observability
Tools for real-time monitoring and tracing help to identify and resolve performance issues.
### Testing and debugging distributed applications
Testing strategies need to evolve to address the challenges of distributed services.
## Best Practices for Microservices
### Domain-driven design and service boundaries
Aligning services with specific business domains helps define clear boundaries and responsibilities.
### Containerization and orchestration
Tools like Docker and Kubernetes facilitate scale deployment and management of microservices.
### Asynchronous communication patterns
Adopting message queues and event-driven architectures enhances scalability and responsiveness.
### Centralized configuration and service discovery
Living configurations and service registries simplify managing dynamic environments.
### Automated testing and continuous delivery
Automation streamlines the testing and deployment processes, enabling faster delivery with higher quality.
## Conclusion
Microservices architecture offers a promising approach to [software development](https://hyscaler.com/insights/enterprise-software-development-benefits/), enabling organizations to achieve greater agility and scalability. However, adopting microservices has challenges that must be carefully considered and addressed.
By following best practices and staying informed about evolving trends, businesses can harness the potential of microservices for future growth and innovation. | rajatp | |

1,888,553 | Nodemon is not for production! | What is Nodemon? Nodemon is a utility that automatically restarts your Node.js application... | 0 | 2024-06-14T12:32:42 | https://dev.to/kameshoff/nodemon-is-not-for-production-3mdj | ## What is Nodemon?
Nodemon is a utility that automatically restarts your Node.js application when file changes in the directory are detected. It is very useful during development because it allows developers to see the effects of their changes immediately without having to manually stop and restart the server.
## Why Not Use Nodemon in Production?
**Performance Overhead**: Nodemon constantly watches files for changes, which can consume additional system resources. In a production environment, minimizing resource usage is crucial for optimal performance.
**Unnecessary Restarts**: In production, the application code is not supposed to change frequently. Automatically restarting the server can lead to unnecessary downtime and disruptions.
**Security Risks**: Allowing automatic restarts based on file changes can be risky. For example, if an unauthorized person gains access and makes changes to files, Nodemon will restart the application with those potentially malicious changes.
**Lack of Control**: Automated restarts can lead to unintended consequences, such as temporary service outages or state inconsistencies. In production, it is important to have controlled and predictable deployments.
## Best Practices for Production
**Use a Process Manager**: Tools like PM2 or Forever are better suited for production environments. They can handle process monitoring, restarts, load balancing, and other management tasks.
**Manual Deployments**: Adopt a deployment process that includes manual checks, testing, and controlled rollouts. Automation tools like CI/CD pipelines can help streamline this process.
**Monitoring and Alerts**: Implement robust monitoring and alerting systems to detect issues and trigger manual interventions when necessary. | kameshoff | |
1,888,552 | Introduction to MongoDB Queries | MongoDB, a popular NoSQL database, provides a flexible and efficient way to manage data.... | 0 | 2024-06-14T12:30:20 | https://dev.to/saumya27/introduction-to-mongodb-queries-3a8h | mongodb, webdev | MongoDB, a popular NoSQL database, provides a flexible and efficient way to manage data. Understanding basic MongoDB queries is crucial for interacting with your database effectively. This guide will walk you through the fundamental operations to get you started with querying MongoDB collections.
**What are Basic MongoDB Queries?**
Basic MongoDB queries involve simple operations that retrieve and manipulate data stored in MongoDB collections. These queries are executed using the find method, which allows you to search for documents that meet specific criteria. Let's explore some of the core MongoDB query operations.
**Retrieving Documents**
The find method is used to retrieve documents from a collection. It can accept a query object to filter the results and a projection object to specify which fields to return.
**Example:**
db.collection.find({ age: { $gte: 18 } }, { name: 1, age: 1 })
This query retrieves all documents from the collection where the age field is greater than or equal to 18, and returns only the name and age fields of those documents.
**Filtering Results**
MongoDB provides various operators to filter results based on specific conditions. Some common operators include:
$eq: Matches values equal to a specified value.
$ne: Matches values not equal to a specified value.
$gt: Matches values greater than a specified value.
$lt: Matches values less than a specified value.
**Example:**
db.products.find({ price: { $gt: 100, $lt: 500 } })
This query finds all documents in the products collection where the price is greater than 100 and less than 500.
**Sorting Results**
To sort the results of a query, use the sort method. This method takes an object where keys are field names and values indicate the sort order (1 for ascending, -1 for descending).
**Example:**
db.users.find().sort({ age: 1, name: -1 })
This query sorts the documents in the users collection first by age in ascending order and then by name in descending order.
Limiting and Skipping Results
You can limit the number of documents returned by a query using the limit method and skip a specified number of documents using the skip method.
**Example:**
db.orders.find().limit(10).skip(5)
This query retrieves 10 documents from the orders collection, skipping the first 5.
**Conclusion**
Mastering [basic MongoDB queries](https://cloudastra.co/blogs/introduction-to-basic-mongodb-queries) is essential for effectively managing and interacting with your MongoDB database. By understanding how to retrieve, filter, sort, limit, and skip documents, you can efficiently perform data operations and build more complex queries as needed. MongoDB's flexible query language makes it a powerful tool for any data-driven application. | saumya27 |

1,888,548 | TypeScript Enums are *more than ok* | As long as you use text-based ones. In TypeScript, enums by default assign numbers as the values in... | 0 | 2024-06-14T12:21:01 | https://dev.to/boscodomingo/typescript-enums-are-more-than-ok-ed6 | webdev, javascript, programming, typescript | **As long as you use text-based ones**.
In TypeScript, enums by default assign numbers as the values in the order the keys are defined. This means that changing existing enums can lead to unwanted changes:
```ts
enum Enum {
key0, // 0
key1 // 1
}
// Later commit, disaster strikes
enum Enum {
key0, // 0
key2, // 1 - this was taken over
key1, // 2
key3 // 3
}
// And again, at a later commit just mayhem
enum Enum {
key2, // 0
key1, // 1
key3 // 2
}
```
We definitely want to avoid that. That's why you should assign values to your enums' keys, the best option being text (numbers still do weird things, watch the videos below to understand more).
# `as const` objects
The biggest opponent to enums is the controversial `as const` object. The implementation goes something like this:
```ts
const ENUM = {
key0: "0",
key1: "1"
} as const;
type EnumKeys = keyof typeof ENUM; // "key0" | "key1"
type EnumValues = typeof ENUM[EnumKeys]; // "0" | "1"
// Which allows for
function example(key: EnumKeys, value: EnumValues): void {
// ...
}
// Both have intellisense
example("key0", ENUM.key0); // Just like regular enums
example("key1", "1"); // But values are accepted too
```
But the thing is string-based enums can already do that:
```ts
enum Enum2 {
key0 = "0",
key1 = "1"
}
// Which allows for
type Enum2Keys = keyof typeof Enum2 // "key0" | "key1"
type Enum2Values = `${Enum2}` // "0" | "1"
function example(key: Enum2Keys, value: Enum2Values): void {
//...
}
// Both have intellisense
example("key0", Enum2.key0);
example("key1", "1"); // Now values are accepted too
```
No need for extra convoluted code that people unfamiliar with TypeScript won't even understand. A much simpler and nicer way to achieve the same goal, using vanilla TS and string interpolation.
And this article doesn't even cover computed values and other awesome features enums have. I genuinely think they are a great addition, and hope the [TC39 proposal](https://github.com/rbuckton/proposal-enum) to implement them in base JS goes through. They are present in almost any modern language for a reason, folks.

Welcome to [**Dapp Mentors!**](https://www.youtube.com/@dappmentors?sub_confirmation=1) In this article, we'll explore decentralized blockchain storage networks, a crucial aspect of building decentralized applications (dApps). Unlike regular blockchain networks, which focus on financial transactions, decentralized storage networks store data files across a network of node providers, ensuring no single point of failure.
You can watch this entire breakdown on this YouTube video, or else you can keep reading on.
{% embed https://www.youtube.com/watch?v=4iJKbjIHqGk %}
## The Need for Decentralized Storage
Regular blockchain networks like Ethereum and Layer Two are expensive for storing large files, making decentralized storage networks a cost-effective solution. Decentralized storage networks like Filecoin, Sia, and Arweave offer cheap data storage, encryption, and permanency, making them ideal for dApp development.
## Filecoin
Filecoin uses IPFS as a protocol for storing and sharing files and has been a pioneer in decentralized storage. I appreciate its storage capacity, which allows developers to store files on the network. The concept of miners, storage providers, and clients ensures that data is stored decentralized, making Filecoin a reliable option. However, data encryption is not built-in, and permanency is not guaranteed. Additionally, market volatility can impact storage costs.
## Sia
Sia's renter-host model impresses me, as it ensures data encryption, compression, and chunking across multiple computers. This network's blockchain regulates data storage, making it a secure option. I appreciate Sia's object-like storage format, similar to AWS's S3 bucket, which makes it easy to understand and work with.
## Arweave
Arweave boasts permanency, which sets it apart from other networks. The ability to store data forever without worrying about removal or inaccessibility is a game-changer. I appreciate Arweave's decentralized platform for building applications, which ensures data permanency. While Arweave does offer encryption tools, data encryption is not a built-in feature of the network. This network has the potential to revolutionize the way we build and store data in dApps.

1,888,537 | How to evaluate GenAI-based assistive search responses? | Many organizations around the world are adopting GenAI technologies in their workflow to make their... | 0 | 2024-06-14T12:10:15 | https://dev.to/ragavi_document360/how-to-evaluate-genai-based-assistive-search-responses-2jgi | Many organizations around the world are adopting GenAI technologies in their workflow to make their teams more productive and to achieve business outcomes that drive business growth.
Technical writers have a huge role in the GenAI era in ensuring trust in GenAI system-generated responses. Technical writers can produce GenAI-friendly content, help train the GenAI systems to produce the right responses based on human feedback, and also evaluate the responses of the GenAI system before deploying it in the production environment.
## Things to Consider in Evaluating GenAI Responses
### 1. Relevancy
The GenAI-generated response should be relevant to the customers’ questions/prompts. The generated response will be relevant if the underlying retrieved mechanism retrieves relevant chunks from the knowledge base. Thus, it is important to look at evaluation metrics about relevancy
### 2. Accuracy
Trust is fundamental in ensuring the adoption of GenAI-based agents. Accuracy plays a crucial role in evaluating the GenAI response. Accuracy metrics can be computed by comparing the GenAI response with the ground truth
### 3. User Feedback
User feedback plays another important role in trust. If GenAI responses are not relevant or non-factual, users can flag them for inaccuracy. This should be considered to retrain the GenAI-based agent to produce accurate responses over time
### 4. Error Handling
If GenAI responses cannot be generated, the response should be courteous
### 5. Response Time
User experience is affected by response time. If the response time is longer, then the user has to wait and they might abandon using GenAI-based agents. A typical balance has to be attained between user experience, cost, and accuracy.
## Framework to Evaluate GenAI Responses
Technical writers are best suited to evaluate the responses generated by GenAI-based assistive search as they curate accurate information across the organization and interact with many subject matter experts. The responses from GenAI-based assistive search are very subjective; thus, it is important to create some baseline around GenAI-based assistive search responses through some numerical metrics.
These metrics can guide improvising responses by either tweaking the underlying content or tweaking the GenAI-based assistive search tool’s functional parameters, such as system messages, chunk size, etc.
Two open-source frameworks are available to evaluate the responses generated by GenAI-based assistive search.

1,888,534 | Case Study: Web Crawler | This case study develops a program that travels the Web by following hyperlinks. The World Wide Web,... | 0 | 2024-06-14T12:08:44 | https://dev.to/paulike/case-study-web-crawler-2c6b | java, programming, learning, beginners | This case study develops a program that travels the Web by following hyperlinks. The World Wide Web, abbreviated as WWW, W3, or Web, is a system of interlinked hypertext documents on the Internet. With a Web browser, you can view a document and follow the hyperlinks to view other documents. In this case study, we will develop a program that automatically traverses the documents on the Web by following the hyperlinks. This type of program is commonly known as a _Web crawler_. For simplicity, our program follows for the hyperlink that starts with **http://**. Figure below shows an example of traversing the Web. We start from a Web page that contains three URLs named **URL1**, **URL2**, and **URL3**. Following **URL1** leads to the page that contains three URLs named **URL11**, **URL12**, and **URL13**. Following **URL2** leads to the page that contains two URLs named **URL21** and **URL22**. Following **URL3** leads to the page that contains four URLs named **URL31**, **URL32**, and **URL33**, and **URL34**. Continue to traverse the Web following the new hyperlinks. As you see, this process may continue forever, but we will exit the program once we have traversed 100 pages.
The program follows the URLs to traverse the Web. To ensure that each URL is traversed only once, the program maintains two lists of URLs. One list stores the URLs pending for traversing and the other stores the URLs that have already been traversed. The algorithm for this program can be described as follows:
`Add the starting URL to a list named listOfPendingURLs;
while listOfPendingURLs is not empty and size of listOfTraversedURLs
<= 100 {
Remove a URL from listOfPendingURLs;
if this URL is not in listOfTraversedURLs {
Add it to listOfTraversedURLs;
Display this URL;
Read the page from this URL and for each URL contained in the page {
Add it to listOfPendingURLs if it is not in listOfTraversedURLs;
}
}
}`
The program below gives the program that implements this algorithm.
```
package demo;
import java.util.Scanner;
import java.util.ArrayList;
public class WebCrawler {
public static void main(String[] args) {
java.util.Scanner input = new java.util.Scanner(System.in);
System.out.print("Enter a URL: ");
String url = input.nextLine();
crawler(url); // Traverse the Web from a starting url
}
public static void crawler(String startingURL) {
ArrayList<String> listOfPendingURLs = new ArrayList<>();
ArrayList<String> listOfTraversedURLs = new ArrayList<>();
listOfPendingURLs.add(startingURL);
while(!listOfPendingURLs.isEmpty() && listOfTraversedURLs.size() <= 100) {
String urlString = listOfPendingURLs.remove(0);
if(!listOfTraversedURLs.contains(urlString)) {
listOfTraversedURLs.add(urlString);
System.out.println("Craw " + urlString);
for(String s: getSubURLs(urlString)) {
if(!listOfTraversedURLs.contains(s))
listOfPendingURLs.add(s);
}
}
}
}
public static ArrayList<String> getSubURLs(String urlString){
ArrayList<String> list = new ArrayList<>();
try {
java.net.URI uri = new java.net.URI(urlString);
java.net.URL url = uri.toURL();
Scanner input = new Scanner(url.openStream());
int current = 0;
while(input.hasNext()) {
String line = input.nextLine();
current = line.indexOf("http:", current);
while(current > 0) {
int endIndex = line.indexOf("\"", current);
if(endIndex > 0) { // Ensure that a correct URL is found
list.add(line.substring(current, endIndex));
current = line.indexOf("http:", endIndex);
}
else
current = -1;
}
}
}
catch(Exception ex) {
System.out.println("Error: " + ex.getMessage());
}
return list;
}
}
```
The program prompts the user to enter a starting URL (lines 9–10) and invokes the **crawler(url)** method to traverse the web (line 11).
The **crawler(url)** method adds the starting url to **listOfPendingURLs** (line 18) and repeatedly processes each URL in **listOfPendingURLs** in a while loop (lines 19–30). It removes the first URL in the list (line 20) and processes the URL if it has not been processed (lines 21–29). To process each URL, the program first adds the URL to **listOfTraversedURLs** (line 22). This list stores all the URLs that have been processed. The **getSubURLs(url)** method returns a list of URLs in the Web page for the specified URL (line 25). The program uses a foreach loop to add each URL in the page into **listOfPendingURLs** if it is not in **listOfTraversedURLs** (lines 25–28).
The **getSubURLs(url)** method reads each line from the Web page (line 42) and searches for the URLs in the line (line 43). Note that a correct URL cannot contain line break characters. So it is sufficient to limit the search for a URL in one line of the text in a Web page. For simplicity, we assume that a URL ends with a quotation mark **"** (line 45). The method obtains a URL and adds it to a list (line 47). A line may contain multiple URLs. The method continues to search for the next URL (line 48). If no URL is found in the line, **current** is set to **-1** (line 51). The URLs contained in the page are returned in the form of a list (line 59).
The program terminates when the number of traversed URLs reaches to 100 (line 19). This is a simple program to traverse the Web. | paulike |

On the road... | 0 | 2024-06-14T12:07:08 | https://dev.to/modenetwork/introducing-houdini-swap-a-privacy-first-cross-chain-liquidity-aggregator-7ak | blockchain, privacy | > **_TL; DR_**
> Move ETH to Mode in one-click privately and compliantly only on [Houdini Swap](https://houdiniswap.com/).
On the road to making cryptocurrency, blockchain tools, and blockchain protocols user-friendly enough for mass adoption, we’ve had innovation and solutions around scalability and security issues. Still, we don’t talk about privacy as much.
Blockchains are designed to be transparent and open to the public by default. While this may be good in some cases it also comes with its fair share of disadvantages. Just by knowing your wallet address anyone can see your transaction history, monitor you, and know exactly the assets that you hold.
This is what Houdini swap solves; In this article, we will understand what Houdini swap is, how it works, and how it solves this privacy issue.
## What is Houdini Swap?
[Houdini Swap](https://houdiniswap.com/) is a leading provider of private cryptocurrency transactions and provides services such as sending, swapping, bridging, and receiving cryptocurrency across major blockchains, all while prioritizing user anonymity and privacy.
Houdini Swap maintains user privacy by concealing the user’s wallet address while they engage in a transaction. At a lower level, it achieves privacy for users by using a dual exchange system and randomized layer 1 chain. Let’s explore this in the next section.
## How does it work?
Houdini Swap's protocol achieves user privacy through a multi-faceted approach that obscures the transaction path and breaks any direct link between the sender and receiver. Here’s a breakdown of how each component contributes to this privacy:
**1. Dual Exchange System:**
**Exchange 1** handles the initial reception of funds and swaps them before sending them across a randomized Layer 1 blockchain.
**Exchange 2** manages the receipt of these funds on the Layer 1 blockchain, swaps them into the receiver's specified token, and dispatches them to the receiver.
By splitting the transaction process between two independent exchanges, each exchange only has partial knowledge of the entire transaction, ensuring that no single party can trace the full transaction path.
**2. Record Segregation:**
**Exchange 1** records the intake and swaps the funds to be sent across a randomly selected Layer 1.
**Exchange 2** records the receipt of funds from the Layer 1 and swaps them into the desired token before dispatching them to the receiver.
This separation ensures that each exchange has only one-half of the transaction information, making it impossible to piece together the complete transaction details from the records of either exchange alone.
**3. Single-Use Wallet Addresses:**
Both exchanges use newly created, single-use wallet addresses for each transaction.
Exchange 1 sends funds to a single-use wallet address of an unknown owner.
Exchange 2 receives funds from a single-use deposit address of an unknown user.
This method prevents any address reuse, making it harder to track transactions based on wallet addresses. Since neither exchange knows that the other is also an exchange, it further obscures the transaction path.
**4. Randomized Layer 1s:**
A randomly selected Layer 1 blockchain acts as an intermediary layer, breaking the direct link between the sender’s original tokens and the receiver’s final tokens. Layer 1 blockchains used in this process are chosen from a diverse portfolio, including chains like TRX, LTC, SOL, and DOT, each with high liquidity and transaction volumes.
The randomization of the Layer 1 blockchain adds a layer of obscurity, making it exceedingly difficult to trace which specific transactions across various blockchains are linked.
**5. Anonymity in Transaction Flow:**
The combination of two exchanges and a randomized Layer 1 ensures there is no identifiable on-chain connection between the sender and receiver. Neither the exchanges nor any external observer can see the full transaction flow. Each exchange only knows about the transactions it directly handles, ensuring that no party has the complete picture.
## How to make use of Houdini Swap
With Houdini swap, you can either send, swap, or bridge your assets. Here you have three easy steps on how to do it:
**Step 1 - Get Your Order Quote**
Select a Crypto pair: Choose which two tokens you want to swap, send, or bridge.
Enter Amount: Enter the crypto amount to be sent. Select **Fixed** for a specified amount to be received. Choose **Variable** to get the best market rates.
Price Optimized: Houdini Swap finds the lowest rates.
No Wallet Connect: For security, you don’t need to connect your wallet.
**Step 2 - Send Your Funds to Start**
Receiving Wallet Address: Input the address of the receiving wallet. Ensure it's on the same blockchain as the receiving currency.
Initiate Order: Send the specified crypto amount to the Houdini Swap address.
**Step 3 - Transaction Completion**
Transaction Processing: Private transactions take 20-40 minutes on average. Semi-private transactions take about 3 minutes.
Track Progress: Follow your transaction's progress once initiated.
## Why Choose Houdini Swap
Below are some reasons why Houdini Swap stands out and why you might consider choosing it.
- Compliant, private transactions
- No need to connect your wallet if you don’t want to
- Non-custodial
- 24/7 support

4. To move an object within the chosen folder, right-click on it and select Move, then Folder.
5. Choose Copy after finding the Gmail folder.
6. The data from the OLM file will be placed in a new Gmail folder within a few minutes.
### Step 4: Integrating a Gmail account with Microsoft Outlook
1. Launch Windows Outlook and set up an identical Gmail account.
2. You can view Mac emails after setting up your Gmail account in Windows Outlook.
### Cons of the Manual Approach
It is best to avoid using manual approaches for the following reasons:
The user can decide to skip some steps because it’s a long process.
If a file gets corrupted and is destroyed throughout exporting or importing, the user’s data can be lost.
There is no assurance that the data will be sent securely using this manual method.
After completion, no specific results are guaranteed.
The entire process is difficult to complete, confusing, and time-consuming.
Users need to be technically competent in order to finish the manual technique.

2. [What is Ledger and why does it need Idempotence?](https://dev.to/woovi/what-is-ledger-and-why-does-it-need-idempotence-18n9)
3. [What is a Ledger and Why Floating Points Are Not Recommended?](https://dev.to/woovi/what-is-a-ledger-and-why-floating-points-are-not-recommended-1f4l)
## What is a Ledger?
A ledger, or accounting book, is a financial record that contains all the debit and credit entries of a business. Whether it’s inventory, a warehouse, or a bank account, a ledger is essentially the book where all financial transactions or movements are documented in an organized and chronological manner. Each entry in the ledger is called a journal entry, which can include various transactions such as sales, purchases, payments, and receipts.
## How Did It Originate?
The earliest records of accounting appeared in ancient civilizations such as Mesopotamia, where clay tablets were used to record commercial transactions. During the Middle Ages, accounting evolved significantly in Europe, culminating with the Italian monk and mathematician Luca Pacioli, who documented the revolutionary double-entry system in his book "Summa de Arithmetica, Geometria, Proportioni et Proportionalità" in 1494. This system, which records each transaction in two accounts (debit and credit), formed the basis of modern accounting. With the digital era, automated systems replaced traditional ledgers, and more recently, blockchain technology introduced distributed ledgers, offering greater security and transparency. Today, ledgers are fundamental to the integrity of financial transactions and the efficient management of resources worldwide.
## How Does It Work?
The operation of a ledger is relatively simple. Each financial transaction is recorded in a double-entry system—this means that for every debit, there is a corresponding credit. For example, if a company makes a sale on credit, it debits the accounts receivable (asset) and credits the revenue account (income). This method ensures that the accounting is always balanced, with the sum of debits equaling the sum of credits.
## How Do Financial/Banking Institutions Use the Ledger?
Financial and banking institutions use ledgers to record all daily transactions. These records include deposits, withdrawals, transfers, loan payments, and interest, among others. Ledgers help maintain transparency, traceability, and integrity of financial records, facilitating audits and ensuring regulatory compliance.
## Calculating the Bank Balance with JavaScript and MongoDB
To calculate the bank balance quickly and efficiently, a common approach is to keep the balance updated in the last entry of the ledger. Let’s illustrate this with an example in JavaScript and MongoDB.
1. Define the structure of the ledger in MongoDB:
```ts
{
_id: ObjectId("60c72b2f9b1d8e4d2f507d3a"),
date: ISODate("2023-06-13T12:00:00Z"),
description: "Deposit",
amount: 1000.00,
balance: 1000.00
}
```
2. Function to add a new entry to the ledger and calculate the balance:
```ts
const { MongoClient } = require('mongodb');
async function addTransaction(description, amount) {
const url = 'mongodb://localhost:27017';
const client = new MongoClient(url);
try {
await client.connect();
const database = client.db('finance');
const ledger = database.collection('ledger');
const lastEntry = await ledger.find().sort({ date: -1}).limit(1).toArray();
const lastBalance = lastEntry.length > 0 ? lastEntry[0].balance : 0;
const newBalance = lastBalance + amount;
const newEntry = {
date: new Date(),
description: description,
amount: amount,
balance: newBalance
};
await ledger.insertOne(newEntry);
console.log('Transaction successfully added:', newEntry);
} finally {
await client.close();
}
}
addTransaction('Deposit', 500.00);
```
**What We're Doing in the Above Example:**
1. Connect to the DB
2. Access the Ledger collection
3. Get the last entry
4. Retrieve the first item of the array sorted by the most recent
5. Calculate the balance
6. Insert the new entry into the collection
## Conclusion
The above code is a simple representation of how to implement a ledger and is far from ideal. In the real world, you need to address issues such as:
- Eventual consistency
- Concurrency
- Idempotency
And many other classic IT challenges.
With this in mind, to design a good ledger, you should at least be able to handle the three topics mentioned above.
So, do you think you can write a ledger?
What would you improve in the above, simplified example?
How would you handle debits? Refunds? Future transactions?
All these challenges are great and occur daily in any field we work in. That's why, in my opinion, you should learn about ledgers.
Learning about ledgers forces you to learn numerous other concepts that will help you find solutions to various problems and will definitely make you stand out in your career.

1,888,530 | Avoiding Beginner Mistakes Hampering You to Scale Backend⚡️ | This blog covers how I unlocked performance that allowed me to scale my backend from 50K requests →... | 0 | 2024-06-14T12:05:21 | https://dev.to/rikenshah/scaling-backend-to-1m-requests-with-just-2gb-ram-4m0c | go, devops, backend, postgres |
This blog covers how I unlocked performance that allowed me to scale my backend from 50K requests → 1M requests (~16K reqs/min) on minimal resources (2 GB RAM 1v CPU and minimal network bandwidth 50-100 Mbps).
It will take you on a journey with my past self. It might be a long ride, so tighten your seatbelt and enjoy the ride! 🎢
*It assumes that you are familiar with the backend and writing APIs. It's also a plus if you know a bit about Go. If you don't, that's fine too. You'd still be able to follow along as I've provided resources to help you understand each topic. (If you don't know GO, here's a* [*quick intro*](https://www.youtube.com/watch?v=446E-r0rXHI)*)*
tl;dr,
First, we build an [observability pipeline](https://www.observo.ai/post/what-is-an-observability-pipeline) that helps us monitor all the aspects of our backend. Then, we start stress testing our backend until breakpoint testing (when everything eventually breaks).

→ [Disabling Implicit Transaction](#optimization-4-ensure-while-testing-there-is-no-blocking-transaction)
→ [Increasing the max file descriptor limit for Linux](#optimization-6-increasing-the-max-file-descriptor-limit)
→ [Throttling Goroutines](#optimization-7-avoid-overloading-goroutines)
→ [Future Plans](#next-steps)
## Intro w/ backend 🤝
Let me give a brief intro to the backend,
- It's a monolithic, RESTful API written in Golang.
- Written in [GIN](https://github.com/gin-gonic/gin) framework and uses [GORM](https://gorm.io/) as [ORM](https://www.theserverside.com/definition/object-relational-mapping-ORM).
- Uses Aurora Postgres as our sole primary database hosted on AWS RDS.
- Backend is [dockerized](https://dev.to/documatic/how-to-dockerize-your-application-536i#:~:text=Dockerizing%20an%20application%20is%20the,for%20developers%20and%20organizations%20alike.) and we run it in `t2.small` instance on AWS. It has 2GB of RAM, 50-100mb/s of network bandwidth, 1 vCPU.
- The backend provides authentication, CRUD operation, push notifications, and live updates.
- For live updates, we open a very lightweight [web socket connection](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) that notifies the device that entities have been updated.
Our app is mostly read-heavy, with descent write activity, if I had to give it a ratio it'd be 65% read / 35% write.
I can write a separate blog on why we choose - monolithic architecture, golang, or postgress but to give you the tl;dr at [MsquareLabs](www.msquarelabs.com) we believe in "Keeping it simple, and architecting code that allows us to move at a ridiculously fast pace."
## Data Data Data 🙊
Before doing any mock load generation, first I built observability into our backend. Which includes traces, metrics, profiling, and logs. This makes it so easy to find the issues and pinpoint exactly what is causing the pain. When you have such a strong monitoring hold of your backend, it's also easier to track production issues faster.
Before we move ahead let me just give tl;dr for metrics, profiling, logs, and traces:
- Logs: We all know what logs are, it's just loads of textual messages we create when an event occurs.
- Traces: This is structured logs high on visibility, that help us to encapsulate an event with correct order and timing.
- Metrics: All the numeric churned data like CPU usage, active requests, and active goroutines.
- Profiling: Gives us real-time metrics for our code and their impact on the machine, that help us understand what's going on. (WIP, will talk in detail in next blog)
To learn more about how I built observability into the backend you can study the next blog (WIP), I moved this section to another blog because I wanted to avoid the reader becoming overwhelmed and focus on only one thing - **OPTIMIZATION**)
This is how visualization of traces, logs, and metrics looks like,
So now we have a strong monitoring pipeline + a decent dashboard to start with 🚀
## Mocking Power User x 100,000 🤺
Now the real fun begins, we start mocking the user who is in love with the app.
"Only when you put your love (backend) to extreme pressure, you find it's true essence ✨" - someone great lol, idk
Grafana also provides a load testing tool so without overthinking much I decided to go with it, as it requires minimal setup of just a few lines of code, there you have got a mocking service ready.
Instead of touching all the API routes I focused on the most crucial routes that were responsible for 90% of our traffic.
Quick tl;dr about [k6](https://k6.io), it's a testing tool based on javascript and golang, where you can quickly define the behavior you want to mock, it takes care of load testing it. Whatever you define in the main function is called an *iteration*, k6 spins up multiple virtual user units (VUs) which processes this iteration until the given period or iteration count is reached.
Each iteration constitutes 4 requests, Creating Task → Updating Task → Fetching the Task → Delete Task
Starting slow, let's see how it goes for ~10K request → 100 VUs with 30 iters → 3000 iters x 4reqs → 12K request
That was a breeze, no sign of memory leaks, CPU overloading, or any kind of bottleneck, Hurray!
Here's the k6 summary, 13MB of data sent, received 89MB, averaging over 52 req/s, with an average latency of 278ms not bad considering all this running on a single machine.
```javascript

_10k_v_hits ✓ [======================================] 100 VUs 07m38.9s/20m0s 3000/3000 iters, 30 per VU
```
Let's ramp up 12K → 100K requests, sent 66MB sent, 462MB received, saw a peak CPU usage to 60% and memory usage to 50% took 40mins to run (averaging 2500 req/min)
Everything looked fine until I saw something weird in our logs, "::gorm: Too many connections::", quickly checking the RDS metrics it was confirmed that the open connection had reached, 410, the limit for max open connection. It is set by Aurora Postgres itself [based on the available memory](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraPostgreSQL.Managing.html#AuroraPostgreSQL.Managing.MaxConnections) of the instance.
Here's how you can check,
`select * from pg_settings where name='max_connections';` ⇒ 410
Postgres spawns a process for each connection, which is extremely costly considering it opens a new connection as a new request comes and the previous query is still being executed. So postgress enforces a limit on how many concurrent connections can be open. Once the limit is reached, it blocks any further attempt to connect to DB to avoid crashing the instance (which can cause data loss)
### Optimization 1: Connection Pooling ⚡️
Connection Pooling is a technique to manage the database connection, it reuses the open connection and ensures it doesn't cross the threshold value, if the client is asking for a connection and the max connection limit is crossed, it waits until a connection gets freed or rejects the request.
There are two options here either do client-side pooling or use a separate service like [pgBouncer](pgbouncer.org) (acts as a proxy). pgBouncer is indeed a better option when we are at scale and we have distributed architecture connecting to the same DB. So for the sake of simplicity and our core values, we choose to move ahead with the client-side pooling.
Luckily, the ORM we are using GORM supports connection pooling, but [under the hood uses database/SQL](https://gorm.io/docs/connecting_to_the_database.html#Connection-Pool) (golang standard package) to handle it.
There are pretty straightforward methods to handle this,
```javascript
configSQLDriver, err := db.DB()
if err != nil {
log.Fatal(err)
}
configSQLDriver.SetMaxIdleConns(300)
configSQLDriver.SetMaxOpenConns(380) // kept a few connections as buffer for developers
configSQLDriver.SetConnMaxIdleTime(30 * time.Minute)
configSQLDriver.SetConnMaxLifetime(time.Hour)
```
- `SetMaxIdleConns` → maximum idle connection to keep in memory so we can reuse it (helps reduce latency and cost to open a connection)
- `SetConnMaxIdleTime` → maximum amount of time we should keep the idle connection in memory.
- `SetMaxOpenConns` → maximum open connection to the DB, as we are running two environments on the same RDS instance
- `SetConnMaxLifetime` → maximum amount of time any connection stays open
Now going one step further 500K requests, (4000 req/min) and 20mins in server crashed 💥, finally let's investigate 🔎
Quickly looking through metrics and bam! CPU and Memory usage spiked. Alloy (Open Telemetry Collector) was hogging all the CPU and memory rather than our API container.
### Optimization 2: Unblocking Resources from Alloy (Open Telemetry Collector)
We are running three containers inside our small t2 instance,
- API Dev
- API Staging
- Alloy
As we dump huge loads to our DEV server it starts to generate logs + traces at the same rate hence exponentially increasing CPU usage and network egress.
So it's important to ensure alloy container never crosses the resource limits, and hampers the critical services.
As the alloy is running inside a docker container it was easier to enforce this constraint,
```javascript
resources:
limits:
cpus: '0.5'
memory: 400M
```
Also, this time logs weren't empty there were multiple context canceled errors - the reason being request timed out, and the connection was abruptly closed.
And then I checked latency it was crazy 😲 after a certain period average latency was 30 - 40 seconds. Thanks to traces now I can exactly pinpoint what was causing such huge delays.
Our query in GET operation was extremely slow, let's run [`EXPLAIN ANALYZE`](https://www.postgresql.org/docs/current/sql-explain.html) on the query,
LEFT JOIN took 14.6 seconds while LIMIT took another 14.6 seconds, how can we optimize this - INDEXING
### Optimization 3: Adding Indexes 🏎️
Adding indexes to fields that are often used in `where` or `ordering` clauses can improve the query performance five-fold. After adding the indexes for the LEFT JOIN table and ORDER fields the same query took 50ms. It's crazy, from **14.6seconds ⇒ 50ms** 🤯
(But beware of adding indexes blindly, it can cause slow death to CREATE/UPDATE/DELETE)
It also frees up connection faster and helps improve the overall capacity of handling huge concurrent loads.
### Optimization 4: Ensure while testing there is no blocking TRANSACTION 🤡
Technically not an optimization but a fix, you should keep this in mind. Your code doesn't try to update/delete the same entity concurrently when you are stress testing.
While going over the code I found a bug that caused an UPDATE to the user entity on every request and as each UPDATE call executed inside a transaction, which creates a LOCK, almost all the UPDATE calls were blocked by previous update calls.
This alone fix, increased the throughput to 2x.
### Optimization 5: Skipping implicit TRANSACTION of GORM 🎭
By default GORM, executes each query inside a transaction which can slow down the performance, as we have an extremely strong transaction mechanism, the chances of missing a transaction in a critical area is almost not possible (unless they are an intern 🤣).
We have a middleware to create a transaction before hitting a model layer, and a centralized function to ensure the commit/rollback of that transaction in our controller layer.
By disabling this we can get [performance gains of at least ~30%](https://gorm.io/docs/transactions.html#Disable-Default-Transaction).
"The reason we were stuck at 4-5K requests a minute was this and I thought it was my laptop network bandwidth." - dumb me
All this optimization led to a 5x throughput gain 💪, now my laptop alone can generate traffic of 12K-18K requests a minute.
### Million Hits 🐉
Finally, a million hits with 10k-13K requests a minute, it took ~2 hours, it should have been done earlier but as alloy restarts (due to resource restriction) all the metrics get lost with it.
To my surprise the maximum CPU utilization during that span was 60% and memory usage was just 150MB.
It's crazy how Golang is so performant and handles the load so beautifully. It has minimal memory footprint. Just in love with golang 💖
Each query took 200-400ms to complete, The next step is to uncover why it takes that much, my guess is connection pooling and IO blocking slowing down the query.
The average latency came down to ~2 seconds, but there is still a lot of room for improvements.
## Implicit Optimization 🕊️
### Optimization 6: Increasing the max file descriptor limit 🔋
As we are running our backend inside a Linux OS, each network connection we open creates a file descriptor, by default Linux limits this to 1024 per process which hinders it from reaching peak performance.
As we are opening multiple web-socket connections if there is a lot of concurrent traffic we'd hit this limit easily.
Docker compose provides a nice abstraction over it,
```javascript
ulimits:
core:
soft: -1
hard: -1
```
### Optimization 7: Avoid overloading goroutines 🤹
As a go developer, we often take a goroutine for granted, and just mindlessly run many non-critical tasks inside a goroutine we add `go` before a function and then forget about its execution, but at the extreme condition it can become a bottleneck.
To ensure it never becomes a bottleneck for me, for the services that often run in goroutine, I use an in-memory queue with n-worker to execute a task.
## Next Steps 🏃♀️
### Improvements: Moving from t2 to t3 or t3a
t2 is the older generation of AWS general-purpose machines, while t3 and t3a, t4g are newer generation. They are burstable instances they provide far better network bandwidth and better performance for prolonged CPU usage than t2
Understanding burstable instances,
[AWS introduced burstable instance](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances.html) types mainly for workloads that don't require 100% CPU for most of the time. So these instances operate on baseline performance (20% - 30%). They maintain a credit system whenever your instances don't require CPU it accumulates credits. When the CPU spike occurs it uses that credits. This reduces your cost and wastage of computing for AWS.
t3a would be a nice family to stick with because their cost/efficiency ratio is much better among burstable instance families.
Here's a nice blog comparing [t2 and t3](https://www.cloudzero.com/advisor/t2-vs-t3/).
### Improvements: Query
There are many improvements that we can make to query/schema to improve speed, some of them are:
- Batching inserts in insert heavy table.
- Avoiding LEFT JOIN by denormalization
- Caching layer
- Shading & Partitioning but this comes a lot latter.
### Improvements: Profiling
The next step to unlock performance is to enable profiling and figuring out what is exactly going on in runtime.
### Improvements: Breakpoint Testing
To discover the limitations and capacity of my server, breakpoint testing is the next step forward.
### End Note 👋
If you have read till the end, you are cracked, congrats 🍻
This is my first blog, please let me know if something is unclear, or if you want a more in-depth dive into the topic. In my next blog, I'll be taking a deep dive into profiling so stay tuned.

1,888,529 | How Cloud Kitchen Business Models Have Transformed the Food Delivery Industry? | The rise of cloud kitchens has sparked a profound change in the food industry in recent years. This... | 0 | 2024-06-14T12:03:12 | https://dev.to/hazeljohnson/how-cloud-kitchen-business-models-have-transformed-the-food-delivery-industry-4281 |
The rise of cloud kitchens has sparked a profound change in the food industry in recent years. This radically new idea has challenged and transformed the traditional restaurant model. This provides restaurants with great flexibility, efficiency and cost-effectiveness. As per the study, a cloud kitchen market has generated $58.91 billion revenue in 022 and is projected to grow at a CAGR of 11.74% from 2024 to 2032. Thus, you can also leverage [On-Demand food delivery app development.](https://www.apptunix.com/solutions/food-delivery-app-development/)
Throughout this article, we will explore cloud kitchens and how they have transformed food delivery services.
**How Does a Cloud Kitchen Work?**
In a cloud kitchen, which is also known as a virtual kitchen, both chefs and kitchen staff prepare food specifically for delivery to customers through various delivery apps.
This type of space is generally rented on an hourly basis or on a monthly basis. One can get all the necessary cooking equipment and technology to process and fulfill online orders without any hassle.
**Why is Cloud Kitchen so successful?**
Cloud kitchens offer many benefits apart from saving costs. Here are some reasons it is considered successful:
-
**Ensures greater hygiene**
Over the last several months, a major number of people have become concerned about their health and safety. This has led to a rise in the popularity of contactless food delivery services like Swiggy and Zomato.
These services make sure that the food is prepared and delivered safely by following strict hygiene standards. Most people prefer ordering food online rather than going to restaurants to minimize the risk of getting sick.
Since cloud kitchens have a limited access policy and follow strict cleaning guidelines, they have become a popular option among many customers.
**- Reduces property costs**
A cloud kitchen offers the best cost-saving opportunity for people. The property is not invested in, electricity is not paid and no employee salaries are paid. This is a great option for businesses to save money on their ventures.

1,888,527 | How Deutsche Telekom MMS optimizes Ansible Playbooks with Steampunk Spotter | Managing Ansible code quality across multiple teams and projects can be challenging. We talked to... | 0 | 2024-06-14T11:58:47 | https://steampunk.si/blog/how-deutsche-telekom-mms-optimizes-ansible-playbooks-with-spotter/ | ansibleplaybooks, successstory, automation | Managing Ansible code quality across multiple teams and projects can be challenging. We talked to **Andreas Hering, System Engineer at Deutsche Telekom MMS** that shared how he and his team handle the complexities of managing diverse Ansible environments with the help of Steampunk Spotter. They not only achieved significant time saving with the Spotter’s rewrite feature, but also experienced 2-4x speedup in Ansible Playbooks improvement, upgrades and maintenance compared to manual methods.
In this blog post, we’ll delve deeper into Deutsche Telekom MMS’s goals, implementation process, results achieved so far, and valuable lessons learned along the way.
## Challenges of managing multiple Ansible versions
At Deutsche Telekom MMS, many teams used Ansible to automate customers’ flows, which means that different teams used various different versions of Ansible. Even though they had tools like Ansible Lint and Renovate to check their code and update Ansible, it became hard to keep their code clean and avoid duplication of roles and collections.
## Where they wanted to go
*“Ideally we wanted to update and upgrade all our Ansible code across all projects to the latest version,”* explains Andreas.
However, with multiple customers and repositories managed by different team members, updating the code became a significant challenge.
Their goals were multi-fold:
* enhance code quality so it is easily understandable by all colleagues in the team,
* improve security by discouraging specific modules,
* align with industry best practices,
* enhance the quality of their open-source projects.
## Setting up Steampunk Spotter
At Deutsche Telekom, they successfully integrated Steampunk Spotter just over 4 months ago. *“When we first tested Spotter out on our code, we realized we had quite a bit of work ahead of us. For example, in one project, the average number of errors per scan and the total number of **detected errors were very high, even though we already had some mechanisms like linting in place**,”* says Andreas.
Initially, they needed to set up an efficient workflow. Since the team primarily uses VS Code, they decided to create a workflow using the Spotter extension for VS Code. Given their multiple customers, they wanted to distinguish the errors and track the progress of each codebase. To achieve this, they created multiple projects in Spotter. *“We created a configuration file with a project ID for each customer’s project. This setup worked excellently with Spotter, as it automatically searches for the config file and uses the project ID to perform scans.”*
However, they also needed a solution for a command-line interface (CLI). They developed a script that facilitates scanning from the CLI by simply typing `spots` followed by the path to scan, along with any additional parameters normally used with Spotter. The script requires the Spotter token and endpoint, which are exported as usual. The team set an alias for `spots` and defined variables to extract the project ID from the VS Code config file in the repository. If no project ID is found, an error is thrown; otherwise, a Spotter scan is performed with the specified parameters.
This script is designed to be used in a bash environment, such as Linux or Windows Subsystem for Linux (WSL). *“We didn’t create a version for PowerShell or Windows command line, but users are welcome to adapt it.”* In Linux, you can add it to your `.bashrc` file to source it at login, allowing you to use the function automatically.
## Optimizing code with Spotter’s powerful features
With the help of Spotter, the Deutsche Telekom MMS team achieved significant progress in a short period. They **elevated their playbooks to modern standards**, fine-tuned sections of the code that were previously neglected due to the lack of time and **incorporated multiple best practices** across more than 10 projects.
Andreas and the team tackled common errors, such as missing fully qualified names (FQCNs) and requirement files. Spotter also identified deprecated code usage and suggested areas where implementing loops could enhance efficiency. Additionally, they optimized the use of Ansible’s copy and template modules by explicitly setting modes, a frequently encountered issue. Their efforts extended beyond internal projects – they made substantial contributions to the open-source Nomad console with a large merge request facilitated by Spotter. They also used Spotter to improve their internal open-source projects.
The Deutsche Telekom MMS team was especially satisfied with the Spotter’s rewriting feature, which they used extensively, especially in the beginning. This feature helped them **easily increase code quality, significantly reducing the workload and saving a lot of time.** *“The total number of rewrites at the beginning was quite high, but I think this is a good sign because it is automatically done by Spotter. We managed to lower the total number of detected errors in the end. This is a valuable feature for us, and it saved us a lot of time,”* explains Andreas.
Furthermore, Spotter fosters **continuous code improvement.** By scanning new code, it aligns it with the latest best practices, ensuring your codebase constantly evolves.
Throughout their journey, our team provided **ongoing support** and made every effort to ensure a seamless and enjoyable user experience. *“Working with you guys was good. We requested one or two features and created bug reports, which you fixed quite fast. You were always open to help,”* explains Andreas.
## Spotter: Enhancing code quality and reducing stress for developers
Andreas highlighted that **Spotter significantly enhances the quality of Ansible Playbooks,** even when existing mechanisms are in place. Its **rewriting feature saves a considerable amount of time, being 2-4 times faster than manual efforts.** Spotter **simplifies upgrades** by checking for deprecations and **offering guidance on necessary changes. It helps developers write state-of-the-art code**, and although the ROI is not directly trackable, it has notably reduced stress for engineers and allowed them to focus on more enjoyable tasks 😉
*“Spotter shines when it comes to writing new playbooks, following best practices and fixing errors in existing playbooks automatically. That’s a great feature and I would definitely recommend Spotter!”* concludes Andreas.

1,880,402 | A quick guide to get started with Meteor.js community | Hello, there! So you just started with Meteor.js or you have been using it for a while, but maybe now... | 8,874 | 2024-06-14T11:55:54 | https://dev.to/storytellercz/a-quick-guide-to-get-started-with-meteorjs-community-43jp | meteor, javascript, beginners, tutorial | Hello, there! So you just started with Meteor.js or you have been using it for a while, but maybe now you want to find some help, talk to other people who use it or a good OSS developer/user want to get at least knowledgeable about the community. This guide/tutorial will introduce you to the basics of Meteor.js community and where to look for people.
My nickname is Storyteller, also known as StorytellerCZ on [GitHub](https://github.com/sponsors/storytellerCZ/) and [X](https://twitter.com/StorytellerCZ). My journey with Meteor.js began back in 2016 as my Master's project ([that is still going today](https://www.literaryuniverse.com)), and what started as a coding interest soon blossomed into a deep passion. Over the years, I've transitioned from a mere coder to a core contributor, even having the privilege to work for Meteor Software for a little bit. Today, I'm a community leader maintaining 60+ packages via [Meteor Community Packages](https://github.com/Meteor-Community-Packages), co-hosting the Meteor Dispatches podcast every Friday, and I've even had the pleasure of organizing the Meteor.js conference (Meteor Impact). With my experience and love for Meteor, I'm here to give you some initial points on how to immerse yourself in this old, but still vibrant community.
In this quick guide, we'll explore the essentials of getting started with Meteor.js beyond the code. You'll discover the various ways to engage with the community, contribute to the project, and leverage the resources available to enhance your Meteor.js journey. Whether you're a seasoned developer or a curious newcomer, there's a place for you in the Meteor.js community. So, let's dive in and explore how you can become an active and valued member of this dynamic ecosystem!
> Before we begin it is important to note that the Meteor community is old and has a lot of history (I'll cover that another time). Some established members can be very direct in voicing their opinion, especially when dealing with corporate communication styles (you could say there is an allergy to that in the community). Loyalty and seniority plays an important part in the community, but that is not at the expense of meritocracy. As everywhere observe and show respects to your seniors and you will be fine.
> Many of the names of projects and products around Meteor have space related themes, so have fun with that if you are building something for Meteor!
## Meteor account
First of you will need to have a Meteor account to access the official websites. You can get that on the [official Meteor website](https://www.meteor.com). By clicking on the [sign-up](https://cloud.meteor.com/?isSignUp=true) button on the top right. You use this account for anything Galaxy related, to publish packages (it is your namespace), so it is a good idea to have even if you won't engage with Galaxy or the community.
## Meteor forums
[Meteor forums](https://forums.meteor.com) are official place for community to gather and you can find all the major historical events there (if you dig deep enough). All the major announcements also happen there as any important conversations from elsewhere, together with links to anything of note.
Keep tap on the forums to stay up to date on the latest from the community and get help for any of your problems. Heck, once in a while we also get [ask to identify meteorites](https://forums.meteor.com/t/identify-this-meteor/51868?u=storyteller) 😁
Anyhow this is where you will need your Meteor account to log in.
## Slack & Discord
Community also runs a Slack and two Discord servers.
While we don't like Slack and want to migrate eventually to Rocket.chat (build on Meteor), right now that is not happening, so if you want to reach out to community immediately and have immediate updates (including newly published/updated packages) Slack is a must. So [join in](https://join.slack.com/t/meteor-community/shared_invite/zt-a9lwcfb7-~UwR3Ng6whEqRxcP5rORZw) on the fun.
For Discord there is the [official server](https://discord.gg/hZkTCaVjmT), but we also have ended up with two community servers, but they are not much used, but if you like Discord and know how to use it well you might be able to start a Renaissance here. [The first server](https://discord.gg/mukjwCA56P) is linked from the official website. [The second server](https://discord.gg/R3dD6rRR) is supposedly more community based, but it doesn't get much traffic.
## GitHub
As any OSS project the development part is happening on GitHub.
### Official
Meteor's long history means that there is quiet a few interesting repositories in the [Meteor's organization](https://github.com/meteor).
One must not miss the main repository for Meteor, but you should know about [Blaze](https://github.com/meteor/blaze), [Reify](https://github.com/meteor/reify) and for React.js users [react-packages](https://github.com/meteor/react-packages) repositories as well. There is much more which I covered previously or still will cover. If you are of the curious sort you might find the precursor to Storybook.js and other gems. 😉
The main discussion is happening on the main Meteor repo and is heavily technical. Discussions are mostly to discuss potential features and technical adjustments. Worth to jump in if you have something to add before you jump into the code itself.
Make sure to also check out [the official blog](https://blog.meteor.com/) once in a while or the [dev.to page](https://dev.to/meteor).
### Meteor Community Packages
Over the years many packages got abandoned or their original creators have moved on. To help maintain the most important community packages [a community organization](https://github.com/Meteor-Community-Packages/) has been created to maintain them and ensure that they can get updated when someone fixes something.

Whether you’re a fresh-faced enthusiast or an aspiring developer, unlocking the secrets of Objective-C opens doors to creating powerful and intuitive applications. **[top interview questions and answers](https://www.onlineinterviewquestions.com/objective-c-interview-questions)** to ace your next tech interview.
Q1. What is Objective-C?
Ans: Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It is primarily used for macOS and iOS development.
Q2. What are the main features of Objective-C?
Ans:
Dynamic typing
Dynamic binding
Dynamic loading
Message passing
Categories and protocols
Automatic Reference Counting (ARC)
Q3. Explain the difference between #import and #include.
Ans: #import ensures that a file is included only once per compilation, preventing circular dependencies. #include allows a file to be included multiple times, which can lead to redundancy.
Q4. What are categories in Objective-C?
Ans: Categories allow you to add methods to existing classes without subclassing. This can be used to extend functionality or organize code better.
Q5. What are protocols in Objective-C?
Ans: Protocols define a list of methods that a class can implement. They are similar to interfaces in other languages and can be either optional or required.
Q6. How do you declare and use a property in Objective-C?
Ans: Properties are declared in the interface section using the @property keyword. For example:
objective
@interface MyClass : NSObject
@property (nonatomic, strong) NSString *name;
@end
The @synthesize directive is used in the implementation to generate getter and setter methods.
Q7. What is the purpose of @synthesize and @dynamic in Objective-C?
Ans:
@synthesize: Automatically generates getter and setter methods for a property.
@dynamic: Informs the compiler that getter and setter methods are implemented elsewhere. | lalyadav |
