They... | 0 | 2024-06-05T12:31:14 | https://dev.to/muhammad_taimur/understanding-api-versioning-a-simple-guide-part-1-theory-4ni5 | csharp, beginners, computerscience, api | APIs (Application Programming Interfaces) are a crucial part of modern software development. They allow different software systems to communicate with each other, enabling the integration of various services and functionalities. But as software evolves, so do the APIs. This is where API versioning comes into play. In this article, we’ll explore what API versioning is, why it’s important, and how to implement versioning is on [part 2 for this article](https://dev.to/muhammad_taimur/understanding-api-versioning-a-simple-guide-part-1-c-code-1p0e).
## **What is an API?**
Before diving into versioning, let’s quickly understand what an API is. An API is like a waiter in a restaurant. Just as a waiter takes your order and brings back your food from the kitchen, an API takes your request, communicates it to a server, and returns the server’s response to you.
For example, when you use a weather app, the app sends a request to a weather API, which then returns the current weather data.
## **Why Do We Need API Versioning?**
As software and applications grow, APIs need to evolve. New features are added, old ones are modified, and sometimes deprecated. These changes can break existing integrations if not managed properly. This is where API versioning helps.
API versioning allows developers to introduce changes without disrupting the existing API consumers (clients). It helps maintain backward compatibility while rolling out improvements and new features.
## **How Does API Versioning Work?**
API versioning involves assigning different versions to an API. Each version can have different endpoints or functionalities. Here’s a simple example:
Let’s say we have a GET /weather endpoint that returns weather data. Over time, we might want to add new data fields or change the format of the response. Instead of modifying the existing endpoint, we create a new version.
**Example:**
- Version 1 (v1):
`GET /api/v1/weather
Response: { "temperature": 25, "humidity": 60 }`
- Version 2 (v2):
`GET /api/v2/weather
Response: { "temp": 25, "hum": 60, "wind_speed": 10 }`
In this example, v2 introduces a new field (wind_speed) and changes the field names (temperature to temp, humidity to hum). Clients using v1 are unaffected by these changes.
## **Common API Versioning Strategies**
Below are the 3 most common ways of API Versioning used by developers
**1. URL Path Versioning**
This method includes the version number in the URL path.
`GET /api/v1/resource
GET /api/v2/resource`
**2. Query Parameter Versioning**
This method includes the version number as a query parameter.
`GET /api/resource?version=1
GET /api/resource?version=2`
**3. Header Versioning**
This method specifies the version number in the request header.
`GET /api/resource
Headers: { "API-Version": "1" }`
To visualize this concept, here’s a simple wording:
Client 1 requests data using v1 endpoint.
Server responds with data in v1 format.
Client 2 requests data using v2 endpoint.
Server responds with data in v2 format.
This separation ensures that changes in v2 do not affect clients using v1. Hence both Apis works as expected.
## **Conclusion**
API versioning is essential for maintaining the stability and reliability of APIs as they evolve. It allows developers to introduce new features and improvements without breaking existing clients. By understanding and implementing API versioning, you can ensure a smooth transition and continued compatibility for your API consumers.
Whether you choose URL path, query parameter, or header versioning, the goal remains the same: to manage changes effectively and keep your API robust and user-friendly.

Some code is readable, some obfuscated. Some code eschews whitespace, as if carriage returns were a scarce natural resource, while other code resembles a living room fashioned by Vincent Van Duysen. Code, like the people who author it, varies.
Yet, it's ideal to minimize variation. Time and effort are best spent on novel problems.
In this post, we'll explore five faux pas often seen in Ruby code and learn how to turn these idiosyncrasies into idioms.
But first, how can we minimize variance in Ruby?
## Minimizing Variance in Ruby with Rubocop and Idioms
Ruby developers can gain efficiency with [Rubocop](https://rubocop.org), which unifies style within a single project or across many projects. Rails is a boon to uniformity, too, as it favors convention over configuration. Indeed, disparate Rails codebases are identical in places and, overall, quite similar.
Beyond tools and convention, variance is also minimized by idioms, or those ["structural forms peculiar to a language"](https://www.merriam-webster.com/dictionary/idiom). For example, Ruby syntax is a collection of explicit idioms enforced by the interpreter. Reopening a class is a Ruby idiom, too.
But not all Ruby idioms are dicta. Most Ruby idioms are best practices, shorthand, and common usages Ruby developers share informally and in practice.
Learning idioms in Ruby is like learning idioms in any second spoken (or programming) language. It takes time and practice. Yet the more adept you are at recognizing and proffering Ruby's idioms, the better your code will be.
## What to Avoid in Ruby
Now, let's move on to looking at five things to avoid in Ruby:
- Verbosity
- Long expressions to detect `nil`
- Overuse of `self`
- Collecting results in temporary variables
- Sorting and filtering in memory
### Verbosity
If you've delved into Ruby, you can appreciate how expressive, compact, fun, and flexible it is. Any given problem can be solved in a number of ways. For example, `if`/`unless`, `case`, and the ternary operator `?:` all express decisions — which one you should apply depends on the problem.
However, per Ruby idiom, some `if` statements are better than others. For instance, the following blocks of code achieve the same result, but one is idiomatic to Ruby:
```ruby
# Verbose approach
actor = nil
if response == 1
actor = "Groucho"
elsif response == 2
actor = "Chico"
elsif response == 3
actor = "Harpo"
else
actor = "Zeppo"
end
```
```ruby
# Idiomatic approach
actor =
if response == 1
"Groucho"
elsif response == 2
"Chico"
elsif response == 3
"Harpo"
else
"Zeppo"
end
```
Almost every Ruby statement and expression yields a value, including `if`, which returns a final code statement value and a matching condition. The version of the `if` statement in the second code block above leverages this behavior. If `response` is `2`, `actor` is set to `Chico`. Assigning the result of an `if` statement is idiomatic to Ruby. (The same construct can be applied to `case`, `unless`, `begin/end`, and others.)
Another Ruby idiom is present: you need not predefine a variable used within an `if` statement (or `while`, `for`, and others). So, the latter code removes the line `actor = nil`. In Ruby, unlike other languages, the body of an `if` statement is _not_ considered a separate scope.
### Long Expressions to Detect `nil`
`nil` represents "nothing" in Ruby. It's a legitimate value and is its own class (`NilClass`) with methods. Like other classes, if you call a method that's not defined on `nil`, Ruby throws an exception akin to `undefined method 'xxx' for nil:NilClass`.
To avoid this exception, you must first test a variable to determine if it's `nil.` For example, code such as this is common in Rails applications:
```ruby
if user && user.plan && user.plan.name == 'Standard'
# ... some code for the Standard plan
end
```
The trouble is that such a long chain of assertions is unwieldy. Imagine having to repeat the condition `user && user.plan && ...` every time you have to reference a user's plan name.
Instead, use Ruby's safe navigation operator, `&.` It is shorthand for the logic "If a method is called on `nil`, return `nil`; otherwise, call the method per normal." Using `&.` reduces the code above to the much more readable:
```ruby
if user&.plan&.name == 'Standard'
// ... some code
end
```
If `user` is `nil` and `plan` is `nil`, the expression `user&.plan&.name` is `nil`.
The example above assumes `user` and `plan` represent a custom structure or Rails model of some kind. You can also use the safe navigation operator if a value represents an `Array` or `Hash`.
For example, assume `a_list_of_values` is an `Array`:
```ruby
a_list_of_values[index]
```
If the variable `a_list_of_values` is `nil`, an exception is thrown. If you expectantly try `a_list_of_values&.[index]`, a syntax error occurs. Instead, use `&.` with the `Array#at` method.
```ruby
a_list_of_values&.at(index)
```
Now, if `a_list_of_values` is `nil`, the result of the expression is `nil`.
### Overuse of `self`
Ruby uses `self` in three substantive ways:
1. To define class methods
2. To refer to the current object
3. To differentiate between a local variable and a method if both have the same name
Here's an example class demonstrating all three usages.
```ruby
class Rectangle
def self.area(length, width)
new(length, width).area
end
def self.volume(length, width, height)
area(length, width) * height
end
def initialize(length, width, height = nil)
self.length = length
self.width = width
self.height = height
end
def area
length * width
end
def volume
area = 100
self.area * height
end
private
attr_reader :length, :width, :height
end
```
`def self.area` is an example of the first purpose for `self`, defining a class method. Given this class, the Ruby code `puts Rectangle.area(10, 5)` produces `50`.
The code `self.length = length` demonstrates the second application of `self`: the instance variable `length` is set to the value of the argument `length`. (The `attr_reader` statement at the bottom defines the instance variable and provides a getter method.) Here, the statement `self.length = length` is functionally the same as `@length = length`.
The third use of `self` is shown in the `volume` method. What does `puts Rectangle.volume(10, 5, 2)` emit? The answer is `100`. The line `area = 100` sets a method-scoped, local variable named `area`. However, the line `self.area` refers to the method `area`. Hence, the answer is `10 * 5 * 2 = 100`.
Consider one more example. What is the output if the `volume` method is written like this?:
```ruby
def volume
height = 10
self.area * height
end
```
The answer is `500` because both uses of `height` refer to the local variable, not the instance variable.
Inexperienced Rails developers make unnecessary use of `self`, as in:
```ruby
# Class User
# first_name: String
# last_name: String
# ...
class User < ApplicationRecord
...
def full_name
"#{self.first_name} #{self.last_name}"
end
end
```
Technically, this code is correct, yet using `self` to refer to model attributes is unnecessary. If you combine Rubocop with your development environment, Rubocop flags this issue for you to correct.
### Collecting Results in Temporary Variables
A common code chore is processing lists of records. You might eliminate records due to certain criteria, map one set of values to another, or separate one set of records into multiple categories. A typical solution is to iterate over the list and accumulate a result.
For instance, consider this a solution to find all even numbers from a list of integers:
```ruby
def even_numbers(list)
even_numbers = []
list.each do |number|
even_numbers << number if number&.even?
end
return even_numbers
end
```
The code creates an empty list to aggregate results and then iterates over the list, ignoring `nil` items, and accumulating the even values. Finally, it returns the list to the caller. This code serves its purpose, but it isn't idiomatic.
A better approach is to use Ruby's Enumerable methods.
```ruby
def even_numbers(list)
list.select(&:even?) # shorthand for `.select { |v| v.even? }`
end
```
`select` is one of many Enumerable methods. Each Enumerable method iterates over a list and collects results based on a condition. Specifically, `select` iterates over a list and accumulates all items where a condition yields a _truthy_ value. In the example above, `even?` returns `true` if the item is an even number. `select` returns a new list, leaving the original list unchanged. A variant named `select!` performs the same purpose, but alters (mutates) the original list.
The Enumerable methods include `reject` and `map` (also known as `collect`). `reject` collects all items from a list where a condition yields a falsey value. `map` returns a new list where each item in the original list is transformed by an expression.
Here's one more example Enumerable method in action. First, some non-idiomatic code:
```ruby
def transform(hash)
new_hash = {}
hash.each_pair do |key, value|
new_hash[key] = value ? value * 2 : nil
end
return new_hash
end
```
And now a more idiomatic approach:
```ruby
def transform(hash)
hash.transform_values { |value| value&.*(2) }
end
```
`transform_values` is another Enumerable method available for `Hash`. It returns a new hash with the same keys, but each associated value is transformed. Remember, even integers are objects in Ruby and have methods. `value&.*(2)` returns `nil` if `value` is `nil`, else `value * 2`.
### Sorting and Filtering in Memory
Here's one last faux pas — this one is specific to Rails and ActiveRecord. Let's examine this code:
```ruby
# class Student
# name: String
# gpa: Float
# ...
#
class Student < ApplicationRecord
...
def self.top_students
Student
.all
.sort_by { |score| student.gpa }
.select { |score| student.gpa >= 90.0 }
.reverse
end
end
```
Calling `Student.top_students` returns all students with a GPA greater than or equal to `90.0` in ranked order, from highest to lowest. Technically, this code is correct, but it isn't very efficient in space or time because:
- It must load all records from the `students` table into memory.
- It first sorts all records and _then_ filters based on GPA, performing unnecessary work.
- It reverses the order of the list in memory.
Sorting and filtering are best performed in the database, if possible, using ActiveRecord's tools.
```ruby
def self.top_students
Student.where(gpa: 90.0..).order(gpa: :desc)
end
```
The shorthand `90.0..` in the `where` clause is a Ruby `Range` expressing a value between `90.0` and `Float::INFINITY`. If `gpa` is indexed in the `students` table, this query is likely very fast and loads only the matching records. If the student records are being fetched for display, more efficiency (in memory) can be gained via pagination (albeit at the possible expense of more queries to fetch the batches).
## Wrapping Up and Next Steps
In this post, we've covered five key things to avoid in Ruby and the idioms to use instead.
I highly recommend reading the documentation for Ruby's core classes and modules, including [`Array`](https://ruby-doc.org/3.3.0/Array.html), [`Hash`](https://ruby-doc.org/3.3.0/Hash.html), and [`Enumerable`](https://ruby-doc.org/3.3.0/Enumerable.html). The documents are a treasure trove of methods and techniques, and chances are a method exists to solve your problem at hand. Turn knowledge into practice by writing small code samples to learn how each method works.
Add Rubocop into your workflow, even your text editor. Rubocop keeps your code looking nice but can also flag idiosyncratic code. Using Rubocop is one of the best ways to learn to code the Ruby way.
Finally, read other developers' code, especially open-source Ruby projects. To peruse the code of any gem, run `bundle open <gem>`, where `<gem>` is the name of a library. If you've included a debugger in your _Gemfile_, you can even set breakpoints in any gem and step through the code.
Go forth and code!

1,878,019 | What is Blum? How can you earn on it? | What is the difference from Notcoin? Blum itself differs in essence from Notcoin, as... | 0 | 2024-06-05T12:23:19 | https://dev.to/__d1b956e23d8b/what-is-blum-how-can-you-earn-on-it-11nc | blockchain, web3 | ## What is the difference from Notcoin?
Blum itself differs in essence from Notcoin, as Notcoin was a simple clicker game where you farmed coins and then sold them on the exchange for real money after listing (the release of securities on the stock exchange). But Blum is a different story. Blum is planned as a decentralized exchange where you can trade various tokens. In the game, you can also farm your own token called BP (Blum Point). It can be farmed in two ways: through a mini-game called "Drop game," where green targets and bombs fall on you, and you need to collect the targets and avoid the bombs because collecting bombs resets your progress in the mini-game. Crystals also fall, and you need to collect them as they stop the time in the mini-game. BP can also be farmed by launching "farming." It's not too complicated; you can simply start farming every 8 hours and go about your business, then collect your BP after 8 hours.
## How to start farming BP?
To start farming, you need to join the closed Blum bot. You can only join it through an invitation, and the number of invitations is limited. Specifically for you, I will leave two links through which you can join Blum.
[1 link (main)
](t.me/BlumCryptoBot/app?startapp=ref_x0AvnsMaRg)
[2 link (if invitations on the first one are exhausted)
](t.me/BlumCryptoBot/app?startapp=ref_svHrSI5fUu)
## Why can you earn 100% on Blum?
It all depends on the developers of this application. The leading developer of this application is Vladimir Smirkis, a former director of Binance (the largest cryptocurrency exchange that left Russia due to certain political events) in the CIS. Blum also won funding in a competition for the most promising crypto projects from Binance.
## When will the cabbage fall into your lap?
According to various insights, you will be able to receive cabbage (earnings) from BP by the end of 2024. However, there are rumors that Blum plans to add farming and other tokens that could have already been listed. This means that you can earn money from Blum even before the end of this year.
## What are the conclusions?
So, if you missed out on Notcoin and missed the opportunity to earn $400-$1000 (which is equivalent to 35,000 rubles to 88,000 rubles), then you definitely need to farm Blum. And even if you didn't miss out, extra money won't hurt. Plus, Blum only requires less than 5 minutes of your time per day.

So I have decided to learn Zig. This is kind of an odd decision because I have never had any interest in Zig. But I have had an interest in Rust for years. Just a little about my background. I am a professional Go developer (well was I've been unemployed for 2 weeks). And during my downtime I decided to pick up a new programming language. This will be the 4th professional language I've learned. My first professional language being Java, then Python years later, now Go for the last 8 years.
## Toy Program to get started
Anyway I plan writing my own message broker. And for no reason other to see if I can. One of my favorite simple things to write in Go are TCP sockets. So figuring out how to do that in Zig was a priority, surprisingly it's not too bad.
So first they suggest that I create a new **_Ip4Address_**. Here it is below.
```zig
const addr = net.Ip4Address.parse("127.0.0.1", 3000);
```
Alright not too painful. I then have to initialize an **_Address_**. This is a struct that takes in an Ip4Address, which I created above. So my next step kind of looks like this.
```zig
var server = try local_addr.listen(.{.reuse_port=true});
defer server.deinit();
```
So what's happening here is pretty cool. We call the "listen" method. Because this can return an error, we call it with "try". This looks suspiciously like an exception. But not to worry, errors are values in Zig, just like Golang. This can alternatively be written like this.
```zig
var server = local_addr.listen(.{.reuse_port=true}) catch |err|{
//handle value
};
defer server.deinit();
```
So the **try** semantic is kind of syntactic sugar. Since I'm new to the language and this was my first day using it, I just went with try, but I can see using the "catch" version for better debugging and logging.
Now finally I'm ready to accept a connection, so lets start our loop.
```zig
while(true){
const conn = try server.accept();
const message = try conn.stream.reader().readAllAlloc(reader_allocator, 1024);
print("{s}", .{message});
reader_allocator.free(message);
}
```
As you can see, we use the "try" syntactic sugar again. Then we obviously read from our connection. What's important is the "readAllAlloc" call. It takes an allocator, and a size which is the size of the allocator. I actually define an "allocator" earlier. I won't get too much into allocators because I only have a super basic understanding of them. But essentially instead of the ownership and borrow checker model found in Rust, we instead can create an allocator structure. We can clean it up whenever we want, but it's usually done via a **defer**. I'm in a an infinite loop, meaning this will never reach the end of the function. So I an deallocating manually with `reader_allocator.free(message)`.
Here is the fully code:
```zig
const std = @import("std");
const net = std.net;
const print = std.debug.print;
pub fn main() !void {
var gpa = std.heap.GeneralPurposeAllocator(.{}){};
defer _ = gpa.deinit();
const reader_allocator = gpa.allocator();
const addr = try net.Ip4Address.parse("127.0.0.1", 3000);
const local_addr = net.Address{.in = addr};
var server = try local_addr.listen(.{.reuse_port=true});
defer server.deinit();
while(true){
const conn = try server.accept();
const message = try conn.stream.reader().readAllAlloc(reader_allocator, 1024);
print("{s}", .{message});
reader_allocator.free(message);
}
}
```
##Thoughts and review so far
So playing around with Zig is actually pretty fun. I've had a lot of false starts with Rust, and it's just hard to get started with. But Zig I was able to just start writing code right away. Zig, while simple, does have a learning curve. But it seems to not be wearing its concepts on its sleeve like Rust. I also think the allocator strategy is genius. And while the Rust borrow checker is also an incredibly good idea, it can make the ownership semantics extremely difficult to work with.
Clearly my program will need some improvements. While this compiles and works, I'm not sending anything back to the client. I also need to build a client as well. Probably put the server in its own package. And I need to figure out what to do with this allocator, because calling it in a loop probably isn't incredibly safe. So I may need to free up memory based on a few conditions, like after a response to the client.
Anyway it's not everyday I'm excited about a new language.

Especially if they frequently need to answer new questions, so they are always asking their technical colleagues to do it for them. This is annoying for the technical colleagues who have to answer these requests all the time, and it’s annoying for the non-technical people because they always have to ask and wait.
Most companies have their data in SQL Databases, and this data contains important information that many employees in the company need in order to make informed, smart decisions. However, extracting this data (ex. to answer a question like “who are my top 3 customers this week?” usually requires writing SQL code to tell the database which data to return. Most people don’t know how to write SQL code and need to ask a technical colleague (wasting everyone’s time), and even if you do know SQL it takes effort to write the correct query.
BlazeSQL is analytics software (Web and desktop app) that uses AI to remove the technical effort from getting data insights. You just tell the chatbot what you want after connecting it to your database, and it does everything for you.
Originally it was actually mainly for technical users, and it just generated the SQL code which you could then copy out. But now, it can also run the code to get the data, graph it, and you can add it to a dashboard inside BlazeSQL. This means that now non-technical users can also use it, and not even see the SQL code. Ex. below is a video of the “non-technical mode” which doesn’t show the SQL code. You can see a video of the technical mode on blazesql.com | blazesql | |

1,878,004 | Exploring The Power Of AJAX Flex In Web Development | AJAX Flex: Enhancing Web Applications with Dynamic Data Interaction AJAX (Asynchronous JavaScript and... | 0 | 2024-06-05T12:11:23 | https://dev.to/saumya27/exploring-the-power-of-ajax-flex-in-web-development-kk | ajax, webdev | AJAX Flex: Enhancing Web Applications with Dynamic Data Interaction
AJAX (Asynchronous JavaScript and XML) and Adobe Flex are technologies used to create rich, interactive web applications. While AJAX is primarily used to asynchronously update web content without reloading the page, Flex is a framework for building expressive web applications that deploy consistently across browsers, desktops, and devices. Combining AJAX with Flex can enhance the capabilities and user experience of web applications.
**Key Features and Benefits**
**AJAX:**
- Asynchronous Communication: AJAX allows web applications to send and receive data asynchronously from a server in the background without interfering with the display and behavior of the existing page.
- Partial Page Updates: By updating only parts of a web page, AJAX improves the user experience by reducing load times and providing more dynamic interactions.
- Enhanced User Experience: AJAX enables more responsive and interactive web applications, improving usability and performance.
- Broad Browser Support: AJAX works with all modern web browsers, making it a widely used technology for web development.
**Flex:**
Rich User Interfaces: Flex provides a framework for building rich, interactive user interfaces with advanced components like charts, graphs, and data grids.
Consistent Deployment: Applications built with Flex deploy consistently across different browsers and operating systems, reducing compatibility issues.
Powerful Data Binding: Flex supports powerful data binding mechanisms, making it easier to synchronize data between the user interface and backend services.
Integration with Back-End Services: Flex can integrate with various back-end services using HTTP, SOAP, and other protocols, facilitating complex data interactions.
**Combining AJAX and Flex**
By integrating AJAX with Flex, developers can leverage the strengths of both technologies to create highly interactive and data-driven web applications. Here are some ways to combine AJAX and Flex:
Asynchronous Data Loading:
Use AJAX to load data from the server asynchronously and then pass this data to Flex components for display. This approach ensures that data updates do not require a full page refresh, improving performance and user experience.
// JavaScript AJAX call to load data
var xhr = new XMLHttpRequest();
xhr.open('GET', 'dataEndpoint', true);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
var data = JSON.parse(xhr.responseText);
// Pass data to Flex component
myFlexComponent.setData(data);
}
};
xhr.send();
Partial Page Updates with Flex Components:
Use AJAX to update parts of a web page dynamically, and incorporate Flex components within those parts for rich interactions.
// AJAX call to update part of the page
$('#content').load('contentEndpoint', function(response, status, xhr) {
if (status == "success") {
// Initialize Flex component with new content
initializeFlexComponent(response);
}
});
Real-Time Data Interaction:
Implement real-time data updates by using AJAX to poll the server for new data and update Flex components dynamically.
// Function to poll server for real-time updates
function pollServer() {
$.ajax({
url: 'realTimeDataEndpoint',
success: function(data) {
// Update Flex component with new data
myFlexComponent.updateData(data);
},
complete: function() {
// Schedule the next poll
setTimeout(pollServer, 5000);
}
});
}
pollServer();
Form Submission and Validation:
Use AJAX for form submissions to validate and submit data without reloading the page. Flex can be used to create interactive forms with rich validation and feedback mechanisms.
// AJAX form submission
$('#myForm').submit(function(event) {
event.preventDefault();
$.ajax({
type: 'POST',
url: 'submitFormEndpoint',
data: $(this).serialize(),
success: function(response) {
// Handle response and update Flex component
myFlexComponent.showSuccessMessage(response.message);
},
error: function(error) {
// Handle error and update Flex component
myFlexComponent.showErrorMessage(error.message);
}
});
});
**Conclusion**
Combining [AJAX Flex](https://cloudastra.co/blogs/exploring-the-power-of-ajax-flex-in-web-development) allows developers to build rich, interactive, and data-driven web applications that provide a superior user experience. AJAX provides the capability to asynchronously communicate with the server and update parts of the web page dynamically, while Flex offers a framework for building sophisticated user interfaces with powerful data binding and consistent deployment across platforms. Together, these technologies enhance the functionality and performance of modern web applications. | saumya27 |

You can choose traditional materials such as wood and iron. Or maybe you prefer modern materials such as composites and vinyl.
All of these materials have their own advantages and disadvantages, but composite fencing has great advantages over them. In this article, we will explore the many advantages of [composite fencing](https://www.evodek.es/informacion-sobre-el-vallado-composite/) as well as some of its disadvantages. This will allow you to learn about this amazing product so you can make the right choice.
What is composite fencing?
Composite fencing is made from a combination of recycled plastic and recycled wood fibers. The combination of these two materials allows it to combine the benefits of wood and PVC/vinyl fencing. Creating a stronger, longer lasting, more durable and environmentally friendly product. It is available in a wide range of colors and, unlike wood fences, it can withstand harsh weather conditions. In addition to this, composite fence is rot, chip and insect resistant.
The unique composition of composite fencing panels gives them many advantages over other fencing materials such as vinyl fences and wood fences. This is why composite fencing has become so popular in recent years.
The pros of composite fencing
There are many reasons to install composite fence in your garden, but some of its benefits may surprise you. So, let's take a look at the pros of composite fencing.
Longevity and durability
Composite fencing is extremely waterproof due to the plastic content in the composite material. Unlike traditional wood fencing, water cannot penetrate inside composite fence. This means that composite fence panels do not form rot easily.
Thanks to its excellent resistance to corrosion, composite fence is generally maintenance free. This is why it lasts much longer than wood fence panels. On average, composite fence has a lifespan of 25 to 30 years.
Composite fence will not break easily and will not need to be replaced in the long run, saving you money in the long run. Compared to traditional wood fencing, composite fencing is a more cost-effective option.
Low Maintenance
Composite fence panels are extremely low maintenance and require little to no maintenance over their lifetime. Wood fencing requires a significant amount of time to seal, treat, stain and paint. Not only are these operations time-consuming, but maintaining the product is quite expensive. Composite fencing, on the other hand, only requires occasional cleaning to keep it looking its best. Once composite fence is installed, you don't need to worry about its care and maintenance.
Easy to install
Installing composite fencing is very simple and does not take much time. The special construction and design makes them very lightweight, which means they are easy to carry and install. Most composite fences feature a small modular design that simplifies and speeds up the installation process. If you are looking for a fence that is quick and easy to install, then a composite fence is definitely the way to go.
Environmentally Friendly
Compared to other fencing materials, composite fence is more environmentally friendly. It is made from recycled wood and recycled plastic, which means that no new trees need to be cut down to make it. And there are no toxins produced during the manufacturing process of composite. The production of vinyl fencing releases many harmful toxins that contribute to land, air, and water pollution.
Unlike wood fencing, composite fencing doesn't need to be replaced as often, making it a more sustainable option. And it requires little maintenance, so you don't need to use sealers, stains or paint.
The cons of composite fencing
As with any other fencing material, there are some cons to using composite fencing. Let's take a look at some of the cons of composite fencing next.
Cost
Composite fencing is more expensive than other popular fencing materials such as wood. In terms of upfront cost, lumber is still the cheapest of all materials. However despite its high initial cost, composite fencing costs less than wood throughout its lifespan. Thanks to the low-maintenance nature of composite material, the overall cost is reduced. Composite fence's long lifespan also means less costly repairs and replacements during its lifespan.
Color may fade
Composite fence has excellent resistance to UV rays and fading. However, darker colored panels are still susceptible to fading over time. The extent to which Composite fence fades depends greatly on the quality of the product. If your composite fence panels show significant fading over time, they may need to be replaced.
Expansion and Shrinkage
Compared to other materials, composite fences are less likely to warp and change size during temperature fluctuations. However, it can still shrink and expand in some extreme weather. In high temperatures, the panels undergo a process of thermal expansion, and in low temperatures, the panels undergo a process of contraction. Unlike wood fences, these changes do not cause composite fence to bend or crack.

1,878,001 | Building Box Steps and Stairs for Decks | Box steps are suitable for transitions between very low decks and multi-level decks. It is also used... | 0 | 2024-06-05T12:08:28 | https://dev.to/oliver_elijah_4f06022c7b2/building-box-steps-and-stairs-for-decks-4dhm | Box steps are suitable for transitions between very low decks and multi-level decks. It is also used when you want to expand your home but are on a budget, which is a cheaper option for expanding your home. Box steps are one of the most practical and aesthetically pleasing touches to a deck.
Box steps are also known as closed riser stairs. not only does it provide safe and easy access to the deck, but it can also be used as extra storage or seating. In this article, we will guide you through the construction of [deck box steps](https://www.evodekco.com/how-do-i-install-box-steps-on-my-outdoor-deck/) and stairs. Providing you with detailed instructions from planning and design to construction and finish work.
Why do deck box steps not have stringers?
The height of your deck will determine whether or not you can use box steps on your deck.For decks with wide staircases, it is a good idea to build box steps. Box steps do not need to be cut or notched and are a little easier to build. A box step is just a series of boxes stacked on top of each other.
If your box step is more than 3 steps, then you should build it with longitudinal beams. Building stairs requires a lot of specialized skills, so consider hiring a professional if you don't think you have enough experience.
Planning and design
Assessing the site
Start by assessing the site where the deck is located. Measure the change in height from the ground to the deck to determine the height that the deck stairs need to cover. Consider the space available for the stairs to ensure there is enough room for comfortable and safe use. Be sure to take into account any existing landscaping or structures that may affect the design and location of the stairs.
Determine treads and risers
The number of treads and risers is critical to the practicality and comfort of the staircase. Calculate the total vertical height and divide by the maximum riser height allowed by your local building code. You can easily arrive at the number of risers needed. Next, calculate the horizontal distance by dividing the total height by the number of treads. Make sure each tread is wide enough to provide a secure foothold.
Material selection
Choose materials for your deck steps that are durable, weather-resistant, and complement the design of your deck. Generally, pressure-treated wood is an affordable yet strong and durable option. However, it requires constant care and maintenance to maintain its appearance. Composite material is a low-maintenance alternative that looks just like wood. Consider the long-term impact of the material you choose, including subsequent longevity and maintenance needs.
Design
Think carefully about your functional requirements for box steps. Do you want them to serve as additional seating or storage? If so, you'll need to design hinged or removable treads for the steps to allow access to enclosed spaces. Consider the overall design style, including the style of the handrail and the impact of the stairs on the visual appeal of the deck.
Building codes and permits
Before beginning construction, consult your local building department for specific code requirements regarding stairs and decks. This includes specifications for tread widths, riser heights, clearances and handrail requirements.
In addition to local building codes, you will need to apply for the necessary permits as required. Permits may require submission of detailed plans and payment of associated fees. Make sure your design meets all code requirements to avoid delays or penalties.
Building box steps for your deck
Marking the area
Mark the area for your deck steps, making sure they are level and in the correct position in relation to the patio. Use stakes and mason lines to outline the perimeter and determine the exact location of each tread and riser.
Constructing the crossbeams
Build the struts, which are the framework that supports the treads. Each transom consists of a center riser and two outer tread supports (riser and tread). Crossbeams should be cut to the correct angle to match the deck elevation to ensure consistent rise and run.
Cutting the treads
Cut the treads to size, making sure they are level and properly supported by the crossbeams. Treadplates should extend slightly beyond the beams to create a neat appearance. Use a circular saw with a fine-toothed blade to ensure accurate cutting and minimize the risk of damage.
Building risers
Make riser boxes to enclose the space between the treads. You can use the same material as the treads or a contrasting material for added visual interest. Depending on the height and design, risers can provide a complete look and add privacy.
Installing the treads and risers
Secure the treads and risers to the beams, making sure they are properly aligned and tightened. Secure the treads and risers with screws or nails to ensure they are tightly fastened.

1,877,997 | Best LLM Inference Engines and Servers to Deploy LLMs in Production | AI applications that produce human-like text, such as chatbots, virtual assistants, language... | 0 | 2024-06-05T12:03:00 | https://www.koyeb.com/blog/best-llm-inference-engines-and-servers-to-deploy-llms-in-production | ai, webdev, programming, opensource | AI applications that produce human-like text, such as chatbots, virtual assistants, language translation, text generation, and more, are built on top of Large Language Models (LLMs).
If you are deploying LLMs in production-grade applications, you might have faced some of the performance challenges with running these models. You might have also considered optimizing your deployment with an LLM inference engine or server.
Today, we are going to explore the best LLM inference engines and servers available to deploy and serve LLMs in production. We'll take a look at vLLM, TensorRT-LLM, Triton Inference Server, RayLLM with RayServe, and HuggingFace Text Generation Inference.
## Important metrics for LLM serving
- **Throughput**: The number of requests from end users processed per second. Also measurable by the number of tokens generated by the model you are using in your application.
- **Latency**: The time taken to process a request from the time it is received to the time the response is sent. TTFT (Time to First Token) is a key metric for measuring the latency of LLMs.
The hard truth about serving LLMs in production is that latency can be long and throughput can be sub-optimal.
All GPUs have a limited amount of memory, and memory is needed for model parameters, results stored in KV cache, and entire batch computations. Without optimizing any of these components, they all compete for precious memory space.
And in worst-case scenarios, they create out-of-memory errors, which crash the server and degrade your application's performance.
LLM inference engines and servers are designed to optimize the memory usage and performance of LLMs in production. They help you achieve high throughput and low latency, ensuring your LLMs can handle a large number of requests and deliver responses quickly.
Knowing which one you should use depends on your specific use case, the size of your model, the number of requests you need to handle, and the latency requirements of your application.
## What is the difference between inference engines and inference servers?
The most important thing to remember about what distinguishes inference engines and servers:
- Inference Engines run the models and are responsible for everything needed for the generation process
- Inference Servers handle the incoming and outgoing HTTP and gRPC requests from end users for your application, collect metrics to measure your LLM's deployment performance, and more.
Here is a simplified overview of their architecture and how they work together with your application:
## Best LLM Inference Engines
### 1. vLLM
Last year, researchers from UC Berkeley released [vLLM](https://blog.vllm.ai/2023/06/20/vllm.html), an open-source inference engine that speeds up LLM inference and serving in production. vLLM leverages PagedAttention, an attention algorithm introduced by the research team based on virtual memory and paging in operating systems.
Applying this PagedAttention when serving LLMs greatly improves the LLM's throughput. When vLLM was released, benchmarks showed how it provided 24x higher throughput compared to HuggingFace Transformers and 3.5x higher throughput than HuggingFace Text Generation Inference.
**How is it faster?**
- The performance improvements are due to the attention algorithm, PagedAttention, which borrows from the classic solution of virtual memory and paging in operating systems.
- Efficient KV cache
- Continuous batching
- Quantization
- Optimized CUDA kernels
**Helpful resources**
- GitHub repository: https://github.com/vllm-project/vllm
- Documentation: https://docs.vllm.ai/en/latest/index.html
### 2. TensorRT-LLM
Created by NVIDIA, TensorRT-LLM is an open source inference engine that optimizes the performance of production LLMs. It is an easy-to-use Python API that looks similar to the PyTorch API.
Several models are supported out of the box, including Falcon, Gemma, GPT, Llama, and more.
An important limitation of TensorRT LLM is that it was built for Nvidia hardware. Also, whichever GPU you use to compile the model, you must use the same for inference.
**How is it faster?**
- Leverages PagedAttention, which frees up memory allocation more dynamically than traditional attention approaches.
- In-flight batching
- Paged Attention
**Helpful resources**
- GitHub repository: https://github.com/NVIDIA/TensorRT-LLM
- Documentation: https://nvidia.github.io/TensorRT-LLM/
## Best Inference Engine and Server
### 1. Hugging Face Text Generation Inference
A solution for deploying and serving from HuggingFace. TGI (Text Generation Inference) uses Tensor Parallelism and dynamic batching to improve performance. Models optimized for TGI include: Llama, Falcon, StarCoder, BLOOM, and more.
**How is it faster?**
- Tensor parallelism when running on multiple GPUs
- Token streaming using SSE
- Continuous and dynamic batching
- Flashed and Paged attention
**Helpful resources**
- GitHub repository: https://github.com/huggingface/text-generation-inference
- Documentation: https://huggingface.co/docs/text-generation-inference/en/index
### 2. RayLLM with RayServe
RayLLM is an LLM serving solution for deploying AI workloads and open source LLMs with native support for continuous batching, quantization, and streaming. It provides a REST API similar to the one from OpenAI, making it easy to cross test.
RayServe is a scalable model for building online inference APIs. Ray Serve is built on top of Ray, allowing it to easily scale to many machines. Ray Serve has native support for autoscaling, multi-node deployments, and scale to zero in response to demand for your application.
Supports multiple LLM backends out of the box, such as vLLM and TensorRT-LLM.
**How is it faster?**
- Continuous batching, quantization, and streaming with vLLM
- Out-of-the-box support for vLLM and Tensor-RTLLM
**Helpful resources**
- GitHub repository: https://github.com/ray-project/ray-llm
- Documentation: https://docs.ray.io/en/latest/serve/index.html
### 3. Triton Inference Server with TensorRT-LLM
Created by NVIDIA, Triton Inference Server is an enterprise offering that accelerates the development and deployment of LLMs in production.
TensorRT LLM is an open source framework created by Nvidia to optimize LLMs performance in production.
TensorRT-LLM does not serve the model using raw weights. Instead, it compiles the model and optimizes the kernels to efficiently serve.
An important caveat about this solution is that it built for Nvidia GPU only. Plus, whichever GPU hardware you use to complie the model, you must use the same for inference. Lastly, TensorRT LLM does not support all LLMs out of the box. Mistral and Llama are supported.
**How is it faster?**
- Paged attention
- Efficient KV caching
- Dynamic batching
- Concurrent model execution
- Out-of-the-box support for multiple deep learning and machine learning frameworks
- Metrics for GPU utilization, server throughput, server latency, and more
**Helpful resources**
- GitHub repository: https://github.com/triton-inference-server/server
- Documentation: https://docs.nvidia.com/deeplearning/triton-inference-server/user-guide/docs/index.html

We like to complain in the industry all the time about imposter syndrome. And it is a real psychological thing that some people have.
But I think we often claim that we are experiencing an imposter syndrome and we are not.
We are just programmers!
Let me give you an example. Myself, after over 10 software projects, every project I joined, and this includes the project I worked on last year.
For the first three months of that project, I'm swimming in frameworks I have never seen, patterns that are maybe somewhat new, weird aspects to the business that I have never encountered.
And yet everybody on the team wants to pretend that they are so experienced, that they know exactly what is going on.
But, if you are actually really intelligent, and you have any sense of self awareness, you will know that I don't know everything that is going on in the project.
And I think if you can become comfortable with that, and just accept that that is part of the job, you are going to have a long career in software.
Now, if you don't like that, you are probably in the wrong position.
Happy Coding!

From leaky roofs to damp basements, water can cause extensive damage if not addressed promptly. That's where waterproofing contractors come in. These professionals specialize in protecting your property from water intrusion, ensuring that your home or business remains safe and dry. In this blog post, we'll explore the importance of [waterproofing contractors in Dubai](https://alrayaninsulation.com/) and how they can help protect your property.
Why Waterproofing is Important in Dubai
Dubai's climate is characterized by hot summers and mild winters, with minimal rainfall throughout the year. However, when it does rain, the city is often hit with heavy downpours that can overwhelm drainage systems and cause flooding. Additionally, Dubai's sandy soil does not absorb water well, leading to runoff and pooling in low-lying areas. This combination of factors makes waterproofing essential for protecting your property from water damage.
Benefits of Hiring [Waterproofing Contractors in Dubai](https://alrayaninsulation.com/)
Expertise: Waterproofing contractors have the knowledge and experience to identify potential problem areas and recommend the best waterproofing solutions for your property.
Quality Materials: Waterproofing contractors use high-quality materials that are specifically designed to withstand Dubai's climate and protect your property from water damage.
Cost-Effective: While hiring waterproofing contractors may seem like an added expense, it can actually save you money in the long run by preventing costly water damage repairs.
Peace of Mind: By hiring waterproofing contractors, you can have peace of mind knowing that your property is protected from water damage.
Common Waterproofing Services
Roof Waterproofing: This involves applying a waterproof membrane to the roof to prevent water from seeping through.
Basement Waterproofing: Basements are particularly susceptible to water damage due to their below-ground location. Waterproofing contractors can apply a waterproof membrane to the basement walls and floors to prevent water intrusion.
Exterior Waterproofing: This involves sealing the exterior walls of your property to prevent water from penetrating.
Interior Waterproofing: In some cases, interior waterproofing may be necessary to protect your property from water damage.
Tips for Hiring Waterproofing Contractors
Experience: Look for waterproofing contractors with a proven track record of success in Dubai.
References: Ask for references from past clients to ensure that the contractor delivers quality work.
Cost: While cost is important, it should not be the only factor you consider. Look for a contractor who offers competitive pricing without compromising on quality.
Insurance: Ensure that the contractor has adequate insurance coverage in case of any accidents or damages during the waterproofing process.
Conclusion
Waterproofing contractors play a crucial role in protecting your property from water damage in Dubai. By hiring a reputable contractor, you can ensure that your home or business remains safe and dry, even during the heaviest rains. If you're in need of waterproofing services, don't hesitate to contact a professional waterproofing contractor in Dubai today.

1,877,988 | The Fascinating Journey of Frontend and Web Development | Hello dev.to community! Today, let’s take a step back and explore the fascinating beginnings of... | 0 | 2024-06-05T11:50:45 | https://dev.to/ismailk/the-fascinating-journey-of-frontend-and-web-development-8g | webdev, javascript, programming, tutorial |
**Hello dev.to community!**
Today, let’s take a step back and explore the fascinating beginnings of frontend and web development. The journey from static HTML pages to dynamic, interactive web applications is nothing short of remarkable.
## **The Dawn of the Web**
In 1991, Tim Berners-Lee, a British scientist, introduced the World Wide Web to the public. The first website, hosted on Berners-Lee’s NeXT computer at CERN, was a simple, text-only page written in HTML. This marked the birth of web development as we know it.
## **HTML: The Foundation**
HTML (HyperText Markup Language) was the first building block of web development. It allowed developers to create and structure content on the web. Early web pages were static, consisting of plain text and basic hyperlinks.
## **Enter CSS: Styling the Web**
As the web grew, so did the need for more visually appealing and structured content. In 1996, CSS (Cascading Style Sheets) was introduced. CSS enabled developers to separate content from design, allowing for more sophisticated and consistent styling across websites.
## **JavaScript: Bringing Interactivity**
In 1995, Brendan Eich created JavaScript, a scripting language that transformed static web pages into dynamic, interactive experiences. JavaScript allowed developers to create real-time content updates, form validations, animations, and much more.
## **The Rise of Frameworks and Libraries**
As web development became more complex, frameworks and libraries emerged to streamline the development process. Libraries like jQuery simplified DOM manipulation and event handling. Frameworks like AngularJS, React, and Vue.js provided structured approaches to building scalable and maintainable web applications.
## **Responsive Design: Adapting to Devices**
With the proliferation of smartphones and tablets, responsive design became crucial. Introduced in the early 2010s, responsive design principles ensured that websites looked and functioned well on all devices, regardless of screen size. CSS media queries and flexible grids were key to this transformation.
## **Modern Frontend Development**
Today, frontend development is a vibrant and rapidly evolving field. Modern tools and technologies such as ES6+, Webpack, and TypeScript have further enhanced the developer experience. Progressive Web Apps (PWAs) and Single Page Applications (SPAs) represent the cutting edge of what’s possible on the web.
## **Conclusion**
From simple HTML pages to sophisticated web applications, the journey of frontend and web development has been driven by innovation and a desire to create better user experiences. As we look to the future, the possibilities are endless, and the web will continue to evolve in exciting and unexpected ways.
Thank you for joining me on this historical journey. Whether you're a seasoned developer or just starting out, it's always fascinating to see how far we've come and where we're headed next. | ismailk |

1,877,986 | Algoritmo A* (A Estrela) | Explicação Teórica O Algoritmo A* (lê-se A-Estrela) é um algoritmo de busca em grafos que utiliza... | 0 | 2024-06-05T11:50:12 | https://dev.to/cristianomafrajunior/algoritmo-a-a-estrela-19ne | **Explicação Teórica**
O Algoritmo A* (lê-se A-Estrela) é um algoritmo de busca em grafos que utiliza funções heurísticas. É amplamente utilizado em problemas de busca, devido à sua eficiência. O objetivo principal do algoritmo é encontrar o caminho mais curto entre dois pontos em um grafo.
O custo total de um nó é dado pela soma de duas funções:
g(x): O custo real do nó inicial até o nó atual.
h(x): A função heurística que estima o custo do nó atual até o nó de destino.
Portanto, a função de custo total (f(x)) é dada por: f(x) = g(x) + h(x)
O Algoritmo A* utiliza essa função de custo para escolher os próximos nós a serem explorados na busca pelo caminho mais curto.
**Principais Características**
**Busca de Melhor-Primeiro**: O A* é uma combinação entre a busca de custo uniforme e a heurística de melhor primeiro. O nó com o menor custo total estimado até o momento é expandido.
**Função de Avaliação**: Utiliza uma função de avaliação que combina o custo real do caminho percorrido até o momento e uma heurística que estima o custo do caminho restante até o destino.
**Eficiente**: Em muitos casos, o A* é mais eficiente que a busca cega, como a busca em largura ou em profundidade, pois utiliza informações adicionais sobre o problema para orientar a busca.
**Introdução ao problema**
Imagine que queremos encontrar o caminho mais curto para viajar por algumas cidades em São Paulo, com o objetivo final de chegar a uma cidade específica.
Cada cidade possui uma distância (em quilômetros) até as outras cidades, fornecendo um contexto realista para aplicar o algoritmo A*.
Desenvolvmemos um Algoritimo em Python para resolução desse problema o repositorio do projeto se encontra aqui:
https://github.com/CristianoMafraJunior/A_Estrela
**Explicação da solução**:
```
class A_Estrela:
def __init__(self):
self.cidades = {
"Araçatuba": {"Votuporanga": 127, "Novo Horizonte": 183, "Marília": 170},
...
}
self.heuristica = {
"São Paulo": 0,
"Santos": 50,
...
}
```
**Inicialização da Classe A_Estrela**
cidades: Um dicionário que representa o grafo das cidades e as distâncias entre elas. Cada cidade tem como valor outro dicionário, onde as chaves são cidades vizinhas e os valores são as distâncias para essas cidades vizinhas.
heuristica: Um dicionário que representa a estimativa de distância (heurística) de cada cidade até o destino final (São Paulo).
**Método a_estrela**:
```
def a_estrela(self, inicio, destino):
fila_prioridade = []
heapq.heappush(fila_prioridade, (0, inicio))
visitados = set()
caminho_percorrido = {inicio: None}
custo_total = {cidade: float("inf") for cidade in self.cidades}
custo_total[inicio] = 0
while fila_prioridade:
custo_atual, cidade_atual = heapq.heappop(fila_prioridade)
if cidade_atual == destino:
caminho = self.reconstruir_caminho(caminho_percorrido, destino, custo_total)
return custo_total[destino], caminho
if cidade_atual in visitados:
continue
visitados.add(cidade_atual)
for vizinho, custo in self.cidades[cidade_atual].items():
novo_custo = custo_total[cidade_atual] + custo
custo_heuristica = self.heuristica[vizinho]
if novo_custo < custo_total[vizinho]:
custo_total[vizinho] = novo_custo
heapq.heappush(fila_prioridade, (novo_custo + custo_heuristica, vizinho))
caminho_percorrido[vizinho] = cidade_atual
return float("inf"), []
```
Fila de Prioridade: fila_prioridade é uma fila de prioridade (min-heap) usada para sempre expandir o nó com o menor custo estimado (custo real + heurística). Inicialmente, ela contém o nó inicial com custo 0.
Conjuntos e Dicionários:
visitados: Um conjunto para rastrear as cidades já visitadas.
caminho_percorrido: Um dicionário para manter o caminho percorrido até cada cidade.
custo_total: Um dicionário para manter o menor custo encontrado até cada cidade. Inicialmente, todos os custos são definidos como infinito (float("inf")), exceto o custo da cidade inicial, que é 0.
Loop Principal: Enquanto houver cidades na fila de prioridade:
Remove a cidade com o menor custo estimado da fila.
Se essa cidade é o destino, reconstrói o caminho usando reconstruir_caminho e retorna o custo total e o caminho.
Se a cidade já foi visitada, pula para a próxima iteração.
Marca a cidade como visitada e avalia seus vizinhos.
Calcula o novo custo para cada vizinho e, se for menor que o custo previamente registrado, atualiza o custo total, adiciona o vizinho na fila de prioridade com o novo custo estimado e registra o caminho percorrido.
**Método reconstruir_caminho**:
```
def reconstruir_caminho(self, caminho_percorrido, destino, custo_total):
caminho = []
cidade = destino
while cidade is not None:
caminho.append((cidade, custo_total[cidade], self.heuristica[cidade], custo_total[cidade] + self.heuristica[cidade]))
cidade = caminho_percorrido[cidade]
return list(reversed(caminho))
```
**Reconstrução do Caminho**:
Reconstrói o caminho desde o destino até o início, usando o dicionário caminho_percorrido. Cada cidade é registrada junto com seu custo atual, heurística e custo total (custo + heurística). O caminho é invertido no final para obter a ordem correta (do início ao destino).
**Uso do algoritimo**:

_Today’s issue is brought to you by_ [Masteringbackend](https://masteringbackend.com?ref=backend-weekly&utm_source=newsletter.masteringbackend.com&utm_medium=referral&utm_campaign=understanding-database-replication) **_→ A great resource for backend engineers. We offer next-level backend engineering training and exclusive resources._**
[In the previous edition](https://newsletter.masteringbackend.com/p/acid-compliance-in-relational-databases), I discussed ACID Compliance in Databases and explored why it’s important, especially in relational databases.
In this episode, I will explain Database Replication, how it works, and the types, advantages, and disadvantages of database replication.
#### What is Database Replication?
A database is one of the most important components of your System Design, and it’s a data store for all your business records.
Imagine if you have only one database server, and it goes down.
Let’s imagine you are building an E-commerce store like Amazon. The store initially has a single database to create, read, and modify data. Everything is perfect. The business grows after a couple of years, and you have millions of customers.
If that one database was to be deleted by mistake or if the server goes down at some point. Your entire business is crumbled.
This can easily be mitigated by having secondary databases that take over whenever the primary database is down. Additionally, all the databases can work together to serve requests.
That’s why Database Replica is a crucial strategy for your database management.
**Database replication** is copying data from one database on a server to one or more replica databases on other servers. The databases then become synced.
#### **How does database replication work?**
Database replication is supported in many database systems, usually with the master/slave relationship. The master or primary database syncs data to the slave/secondary databases. A popular configuration is the master processing data-modifying operations like insert, update, and deletes.
The master then syncs the data to the slaves, which supports data read operations since applications require a much higher ratio of reads to writes; thus, the number of slaves should always be higher to scale and process most of the requests.
In this setup, if the master database goes offline, a slave database will be promoted as the new master to process data modifying requests and sync data to the slaves. However, in production, promoting a new master can be complicated as the slave data might not be up to date.
The missing data needs to be updated by running recovery scripts. If only a single slave database is available and it goes down, the read operations will be directed to the master database. Immediately after the issue is found, a new slave database will replace the old one, and data will be synced.
If our architecture has multiple slave databases, read operations will be directed to the healthy ones.
#### **Types of database replication**
We just described a master-slave replication in which one database is designated as the master and others as slaves.
The master receives all the write operations, whereas the slaves handle the read operations. Other types of database replication are:
1. Multi-Master replication: In this setup, we have more than one master database and one or more slaves. The masters receive write operations, then the changes are synced to the other databases. A [load balancer](https://masteringbackend.com/hubs/system-design/load-balancers?utm_source=newsletter.masteringbackend.com&utm_medium=referral&utm_campaign=understanding-database-replication) distributes the traffic to the masters.
2. Master-Master(Peer-to-peer) replication: All the databases acts as both a master and a slave, the data is replicated across all nodes in a peer-to-peer fashion.
3. One-Way Replication: In this type of replication, data is replicated from a master database to one or more slave databases in one direction only. This is useful for backup and reporting purposes. It is also known as data mirroring, where complete backups are maintained when the primary database fails. Mirrors act as hot standby databases.
#### **Advantages of database replication**
1. **High Availability — ** Your system will remain available if your primary database fails.
2. **Improved Scalability-** The traffic is distributed to the replicas, so the system can effectively handle a surge in traffic.
3. **Lower latency-** Database replication can improve latency by reducing the time it takes to access data. When data is replicated to multiple databases, it can be accessed from a database geographically closer to the user, reducing the time it takes to access the data.
4. **Disaster recovery:** Database replication can create a disaster recovery site in a separate location. In a disaster, the replicated data can restore operations quickly.
#### **Disadvantages of database replication**
1. **Complexity:** Database replication can be complex to set up and maintain, especially for multi-master replication scenarios. Configuration, management, and monitoring can require additional resources and expertise.
2. **Consistency:** With replication, there is a risk of inconsistent data if updates are made to different database copies simultaneously. This can lead to conflicts that need to be resolved.
3. **Performance impact:** Replication can have a performance impact on the database, especially during heavy write operations. This is because each update needs to be propagated to all the replicas, which can cause delays and increase system load.
4. **Cost:** Replication can require additional hardware and software licenses, increasing costs. Maintaining multiple copies of the data can also require additional storage and bandwidth.
5. **Security:** Replication can increase the risk of data breaches or other security issues. Each copy of the data is a potential target for attacks, so additional security measures may be required to protect the replicated databases.
Database replication aims to provide redundancy and fault tolerance in case of hardware or software failure.
It also improves application performance by reducing the load on the primary database server and distributing read requests across multiple replicas, improving your application performance, scalability, and availability.
Additionally, replication can be used for data mirroring, where complete backups are maintained when the primary database fails.
That will be all for this week. I like to keep this newsletter short.
Today, I discussed Database Replication, how it works, and the types, advantages, and disadvantages of database replication.

Instead they... | 0 | 2024-06-05T11:35:31 | https://dev.to/tharindufdo/understanding-dependency-injection-in-spring-boot-2ll0 | dependencyinjection, java, springboot, programming | In simple terms DI means that objects do not initiate their dependencies directly. Instead they recive them from an external source.
- When class A uses some functionality of class B, then its said that class A has a dependency of class B.
**What is DI in Spring Framework?**
Dependency Injection (DI) is a fundamental concept in Spring Framework that makes it possible to develop loosely coupled and easily testable code. In this blog, we'll explore what dependency injection is, how it works in Spring Boot, and provide examples to illustrate its usage.
There are three main types of dependency injection:
1. Constructor Injection
2. Setter Injection
3. Field Injection
## Constructor Injection
This is the most recommended way to acheive DI in Spring.It ensures that the dependency is not null and makes the class immutable.
```
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class TestService {
private final TestRepository repository;
@Autowired
public TestService(TestRepository repository) {
this.repository = repository;
}
public void performService() {
repository.doSomething();
}
}
```
In the example above, **TestService** class declares a dependency on **TestRepository**. The dependency is injected via the constructor, which is annotated with @Autowired.
## Setter Injection
Setter injection allows the dependency to be injected through a setter method. This method is less preferred than constructor injection because it allows the object to be in an incomplete state.
```
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class TestService {
private TestRepository repository;
@Autowired
public void setTestRepository(TestRepository repository) {
this.repository = repository;
}
public void performService() {
repository.doSomething();
}
}
```
In this example, TestService class has a setter method setTestRepository, which is used to inject the TestRepository dependency.
## Field Injection
Field injection is the least preferred method because it makes the class less testable and harder to maintain. It involves annotating the dependency field directly with @Autowired.
```
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class TestService {
@Autowired
private TestRepository repository;
public void performService() {
repository.doSomething();
}
}
```
Here, TestRepository is injected directly into the field of TestService using @Autowired.
## Qualifiers
When there are multiple beans of the same type, you can use @Qualifier to specify which bean should be injected.
```
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
@Service
public class TestService {
private final TestRepository myRepository;
@Autowired
public TestService(@Qualifier("specificRepository")TestRepository repository) {
this.repository = repository;
}
public void performService() {
repository.doSomething();
}
}
```
In this example, @Qualifier("specificRepository") specifies that a particular implementation of TestRepository should be injected.
## Conclusion
Dependency Injection is a powerful pattern that helps to create loosely coupled, maintainable, and testable applications. Spring Boot leverages dependency injection to manage the lifecycle and configuration of application components, making development more straightforward and efficient. By understanding and applying constructor, setter, and field injection, as well as using qualifiers when necessary, you can create robust Spring Boot applications.

1,877,980 | Day 14 of 30 of JavaScript | Hey reader👋 Hope you are doing well😊 In the last post we have seen an introduction of OOPs. In this... | 0 | 2024-06-05T11:33:44 | https://dev.to/akshat0610/day-14-of-30-of-javascript-145a | webdev, javascript, beginners, tutorial | Hey reader👋 Hope you are doing well😊
In the last post we have seen an introduction of OOPs. In this post we are going to know about objects in JavaScript, we are going to start from very basic and take it to advanced level.
So let's get started🔥
## What are Objects?
**In JavaScript, an object is a collection of properties**, where each property is associated with a key (also known as a name or identifier) and a value. Objects can be used to store related data and functionalities together, allowing for more organized and modular code.
Example -:
`const man={
name:"John",
age:45,
nationality:"Indian",
country:"India"
}`
So this is a `man` object which has name, age, nationality and country as its properties.
These properties are key-value pair the entity present on left side of colon is key and the entity to the right of colon is value.
The object can contain methods too.
The objects are dynamic in nature i.e. properties and methods can be added or deleted at any time.
But you may be thinking that earlier we have defined objects as instace of classes but here we are defining it in other way?? 🤔
The reason is simple we are using objects in different ways due to the flexible nature of JavaScript. JavaScript is not class based OOPs but it does support class based OOPs in ES6.
## Creating a JavaScript Object
**Using `new()`**
**Object Literal**
**Using Constructor**
Constructor Function is used to initialize the properties of a class or function.
So here to create person1 object we will call constructor function with name and age as arguments , the name key in constructor function will get value provided by us.
Using constructor function we can define different objects of same type.
These are the four ways through which we can create JavaScript object.
## Accessing and Modifying Properties
We can the property of Object using `.`(dot) notation or `[]`(bracket) notation.
Nearly everything in JavaScript is object, we have arrays as objects, maps as objects,dates as objects and many more are there.
## Object Prototype
In simple terms, **the object prototype in JavaScript is like a blueprint or template that defines properties and methods that all objects inherit by default.** It's a way for objects to share behavior and functionality without duplicating code.
Example-:
Here you can see that we have defined a template for animal and later used this as prototype and with the help of this created a dog object.
Now you may be thinking that we have constructor function through which we can create different objects of same type then why we are in need of this Prototype?🤔
So here are some reasons-:
- Prototypes allow for more memory-efficient code. When you create objects using a constructor function, each instance gets its own copy of methods defined within the constructor. In contrast, methods defined on a prototype are shared among all instances, reducing memory usage.
In this case, person1 and person2 each have their own sayHello method, which consumes additional memory for each instance.
In this case, person1 and person2 both reference the same sayHello method defined on the prototype. This means that the method is stored only once in memory and shared among all instances, leading to memory savings.
- Prototypes enable you to add or modify properties and methods dynamically, even after objects have been created.
- You can extend built-in JavaScript objects, such as Array, String, and Object, by adding custom methods to their prototypes. This enables you to enhance the functionality of these objects to suit your specific needs.
This is it for Objects I hope you have understood it well. In the coming blogs we will learn more about the objects. In the next blog we are going to learn about `this` keyword. Till then stay connected and don't forget to follow me .
Thankyou🤍

As explained in [Rails association reference](https://guides.rubyonrails.org/association_basics.html#methods-added-by-has-many), defining a `has_many` association gives **17** methods.
We'll focus on the `collection_singular_ids=(ids)` part.
```rb
class Book
has_many :book_genres
has_many :genres, through: :book_genres
end
class Genre
has_many :book_genres
has_many :books, through: :book_genres
end
# the tie model
class BookGenre
belongs_to :book
belongs_to :genre
end
```
Given a `book`, we'd get a `genre_ids=` (from `has_many :genres`). This method is very powerful. It's designed in such a way that you can use the value as-is straight from controller params in mass-assigment, and only the genres you specified would remain. Yes, `genre_ids=` will take care of identifying assocs being removed and new ones being added and only apply the change, not touching unchanged records!
```rb
book.genre_ids #=> [1, 2]
# this will delete the BookGenre record tying this book to genre 1
# and create a new one tying it to genre 3, leaving tie to 2 unchanged!
book.update!(genre_ids: ["2", "3"])
book.genre_ids #=> [2, 3]
```
This only leaves validation errors. Say you want to validate that every book has at least one genre specified.
Easy, you can even use a macro validation:
```rb
Book.validates :genre_ids, length: { minimum: 1, message: :at_least_one_required }
```
The last piece of the puzzle is how will the form react. You may need to align what field/helper you are using, so validation errors color the field nice and red on any problems.
```rb
<%= f.input :genre_ids %>
# or maybe
<%= f.association :genres %>
```
Just make sure the param being submitted is `:genre_ids`, so mass-assignment works.
For StrongParams you may need to do this:
```rb
params.require(:book).permit(
:title, genre_ids: []
).
```

As [Emmy Cao](https://www.linkedin.com/in/emmycao/) (Developer Advocate, Wix) says, **our brain is plastic and fantastic** – it’s really good at changing and adapting.
Also, it’s very efficient—if you do something every day, that behavior will become automatic.
Let’s apply that to programming.
## Do, repeat – and be intentional!
What’s the best new programming thing to learn or the best framework to use at the moment?
Well, maybe that’s not THE question. For Emmy, the number one skill for developers is not tactical **but the ability to learn**. And for learning, repetition is the key.
> When thinking about repetition and practice in programming, it’s important to be intentional. Consider the difficulty and context of your tasks. Are you challenging yourself? Are you improving within the same context or trying new ones?
>
> A common issue is **getting stuck in ‘tutorial hell** ‘, where you keep doing tutorials because they’re easy. To truly grow, you need to apply your knowledge, not just repeat it.
In programming, adds Emmy, it’s often said, “If your GitHub doesn’t look like this, what are you doing?” But the best approach depends. “Are you focusing on one repository or multiple projects? Working long-term on one project hones specific skills while tackling various projects broadens your experience across different contexts.”
## Find the right challenge for your brain
In addition to repetition, we should use proven methods from psychology and cognitive science to learn: **test our knowledge, add new challenges, and practice in varied contexts**.
“[Pair programming](https://shiftmag.dev/pair-programming-benefits-challenges-563/) is beneficial because it exposes you to different workflows and thought processes. Rubber duck programming works because explaining your code linearly helps you understand it better”, says Emmy and adds:
_Flow and focus states are crucial for productivity, and creativity often comes passively. Flow usually occurs when you’re really good at something but also find it challenging. It’s about finding the right challenge for your brain._ Other factors include **well-defined challenges, time constraints, and personal interest.**
> The brain has two states of thinking: the default mode network and the task-positive network, or focus and diffuse states. Focused thinking is good for solving highly technical problems, while diffuse thinking allows for creativity and random thoughts. Taking breaks is important because it allows for diffuse thinking, leading to creative solutions.
And don’t forget the Dunning-Kruger effect: **the loudest, most confident people often lack experience**. As you go deeper, you realize how much you don’t know. Beginners tend to be the most confident, while experts and intermediates often feel they’ll never master it all.

Does your monthly AWS bill make Ebenezer... | 0 | 2024-06-05T11:20:42 | https://dev.to/abhiram_cdx/channel-your-inner-scrooge-with-redshift-reserved-instances-slash-your-cloud-bill-like-a-boss-4kl1 | redshift, aws | ## Feeling the pinch of ever-growing cloud costs?
Does your monthly AWS bill make Ebenezer Scrooge look like a free spender? Fear not, data wizard! Redshift Reserved Instances (RIs) are here to unleash your inner penny-pinching champion and transform you into a cloud cost-cutting crusader!
But what are Redshift RIs, you ask? Imagine Redshift clusters as your personal data warehouse – a digital vault overflowing with precious information. RIs are like pre-paying rent on those virtual warehouses. Commit to using them for a set period (think one or three years), and Amazon rewards you with significant discounts – like a savvy shopper who snags a bulk discount on storage units!
## The Benefits of This Reserved Warehouse Strategy:
- **Slash Your Cloud Bill:** Get ready to see those cloud costs plummet! RIs offer substantial savings compared to the standard on-demand pricing for Redshift clusters. The longer you commit, the deeper the discounts – the more upfront time you rent the warehouse, the cheaper the monthly rate.
- **Predictable Spending, Happy Budgeting:** RIs bring predictability to your cloud expenses. No more bill shock at the end of the month – it's like having a fixed rent for your data warehouse, allowing you to plan and budget your data analysis endeavors with laser focus.
- **Guaranteed Warehouse Availability:** With RIs, you secure the data storage space you need, ensuring your Redshift clusters are always at your beck and call. No more scrambling for storage space at the last minute – it's like reserving specific rooms in your data warehouse, guaranteeing you have the space to store all your analytical treasures.
But hold on to your data goggles! Before you dive headfirst into RIs, there are a few things to consider:
- **Commitment is Key:** RIs lock you into a usage term, so make sure your Redshift needs are predictable. Don't be like an overzealous apprentice who rents a giant warehouse to store a single potion – ensure your data workload justifies the RI investment.
- **Pick the Right Warehouse Size:** Just like choosing the right cauldron size for your potion, selecting the appropriate RI type (size and configuration) is crucial. Picking the wrong size warehouse for your data storage needs could lead to inefficiencies – don't try to cram a mountain of information into a tiny storage unit.
Redshift RIs can be your golden ticket to cloud cost savings, but a little planning goes a long way. By understanding your data usage patterns and selecting the optimal RIs, you can transform yourself into a master of cloud cost optimization. Remember, with the right approach, your data analysis projects won't just be insightful – they'll be downright frugal!

These cells are in constant contact with airborne pathogens and pollutants on a daily basis. These cells are part of regular research and are used in disease modeling, drug discovery, and tissue engineering. Researchers use these cells to test drugs for their aerosol transmission capabilities and effectiveness. These cells are collected when a donor agrees to tracheal tissue biopsies, which plays a crucial role in their availability. Hence, getting high-quality primary cells from a cell manufacturer that follows the strict guidelines for cell isolation, expansion, and delivery is the next best step.
As an alternative, induced pluripotent stem cells (iPSCs) are used. However, it takes a long time to get the cells to look, act, and be characterized like tracheal epithelial cells. To expedite our research and get reproducible results that will lead to reproducible results in "in vivo systems" as well, you can turn to primary cells that have the same physiological signaling rather than testing it in an induced system.

---
In large commercial projects or for indie developers who have numerous apps already developed, the biggest problem is always managing multiple versions of Flutter for all these projects. It is normal for frameworks to evolve, and with this, problems occur. We don't always have the time to migrate all projects to the latest version, or we have dependencies that need more time to be adapted to the latest version. This is where the solution provided by FVM, developed by Leo Farias, comes into play. FVM allows for the management of multiple Flutter installations and the ability to switch between them easily through a practical CLI.
## What is FVM?
FVM is an open-source tool designed to make Flutter version management easier. It allows developers to install, manage, and switch between different Flutter versions seamlessly. Whether you are working on multiple projects that require different versions of Flutter or collaborating with a team, FVM ensures consistency and reduces the overhead of version conflicts.
## Key Features of FVM
1. **Version Isolation**: Keep project dependencies isolated by specifying a Flutter version for each project.
2. **Team Collaboration**: Ensure all team members use the same Flutter version, avoiding "it works on my machine" issues.
3. **Easy Version Switching**: Quickly switch between Flutter versions without the hassle of manually downloading and configuring them.
4. **Global and Local Versions**: Set global Flutter versions for all projects or override them with specific local versions per project.
5. **Fast Setup**: Install and set up specific Flutter versions quickly using simple commands.
## Instalation
The installation steps are for operating systems, but it is available on the most common tools on each platform. It can be installed as a Flutter dependency, but this is the least recommended option since we want FVM to be an independent operating system tool for managing versions.
### macOS
```sh
brew tap leoafarias/fvm
brew install fvm
```
### Windows
```sh
choco install fvm
```
### Linux
```sh
curl -fsSL https://fvm.app/install.sh | bash
```
### Dart
```sh
dart pub global activate fvm
```
The project already has documentation on how to integrate management with the two main IDEs used, Android Studio (IntelliJ) and VS Code. It detects and indicates what needs to be configured in the project through a command:
```sh
fvm doctor
```
## Effortless Version Switching
Switching between Flutter versions is hassle-free with FVM. Whether you’re testing a new Flutter release or maintaining an older project, FVM allows you to switch versions with a single command.
```sh
fvm install 3.19.2
fvm use 3.19.2
```
This command sets Flutter version 3.19.2 for your current project, ensuring everyone on your team is using the same version. That's the config `.fvmrc` file generate inside the project folder.
```json
{
"flutter": "3.19.2"
}
```
This sets the global Flutter version to 3.22.0, which will be used across all your projects unless overridden locally.
```sh
fvm global 3.22.0
```
## For teams
In the case of teams, it is always interesting to have a way to ensure that everyone on the team knows the correct library version required for the project. Once the local version is within the project directory, it can be easily configured with just one command.
```sh
fvm install -s
```
## Beta
Another case is to check if the application continues to exhibit the same behavior in the **beta** version of the library. Mobile applications, in particular, benefit greatly from always using the latest version, which typically brings improvements that can help enhance their performance in app stores.
```sh
fvm install beta -s
```
## Conclusion
As the Flutter development environment grows and becomes a productivity tool for developers, it is normal for the ecosystem tools that allow us to manage and maintain high performance in projects to grow as well. FVM is a very interesting tool that every Flutter developer should keep an eye on.

1,877,922 | The Wizard's Guide to GORM and PostgreSQL: Upsert with Ease | Interesting story. You have two PostgreSQL tables related to each other in a one-to-many... | 0 | 2024-06-05T11:13:45 | https://dev.to/kochurovro/conquering-postgresql-challenges-upserting-records-with-gorm-magic-1mnd | Interesting story. You have two PostgreSQL tables related to each other in a one-to-many relationship.
```
type Availability struct {
ID int64 `gorm:"column:id;primaryKey"`
ProductID int64 `gorm:"column:product_id"`
Enabled bool `gorm:"column:enabled;not null"`
Dates []*Dates `gorm:"foreignKey:AvailabilityID"`
}
type Dates struct {
ID int64 `gorm:"column:id;primaryKey"`
AvailabilityID int64 `gorm:"column:availability_id;foreignKey:Availability" json:"availability_id"`
Date string `gorm:"column:date"`
}
```
And such an index product_availability_dates_uindex(AvailabilityID, date) in the Dates table. You need to update the Enabled field in the Availability table using GORM. If such a record does not exist, create it.
```
func (that *AvailabilityRepo) Upsert(ctx context.Context, pa []*model.ProductAvailability) error {
for _, a := range pa {
tx := that.db.WithContext(ctx).Model(&model.ProductAvailability{}).
Where("product_id = ?", a.ProductID).
Update("enabled = ?", a.Enabled)
if tx.Error != nil {
return fmt.Errorf("%w: failed to update product availability", tx.Error)
}
if tx.RowsAffected == 0 {
if err := tx.Create(&a).Error; err != nil {
return fmt.Errorf("%w: failed to create product availability", err)
}
}
return nil
}
}
```
Problem 1. We need to return the ID if the field is updated. Currently, the ID is not being returned. We try to pass the instance of the object directly in the Model. This method seems to work, but not for me.
```
func (that *AvailabilityRepo) Upsert(ctx context.Context, pa []*model.ProductAvailability) error {
for _, a := range pa {
tx := that.db.WithContext(ctx).Model(&a).
Where("product_id = ?", a.ProductID).
Update("enabled = ?", a.Enabled)
if tx.Error != nil {
return fmt.Errorf("%w: failed to update product availability", tx.Error)
}
if tx.RowsAffected == 0 {
if err := tx.Create(&a).Error; err != nil {
return fmt.Errorf("%w: failed to create product availability", err)
}
}
return nil
}
}
```
Why the above update did not work for me. The first reason, it makes me want to wash my hands after such an approach. The second reason is that the tables are connected through a unique index. And GORM, by some internal magic, returns an error because the uniqueness index is triggered. You didn't touch the dates field, but the error will be related to this index.
How I solved the problem for myself:

It felt good to retrospect and I'm also pretty proud of them, so I'll be reposting some of them here...._
I'm 11 weeks into coding bootcamp and my mind is turning towards a subject for my next blog. This weekend is a little different from the previous ones - all the code challenges have been taken and passed, next week we continue working on our paired projects and then its onto the final module, the one where all our learning comes together in projects we will conceive and build by ourselves.
We have all written and given our Flatiron School Presents presentations. There are no labs to be done in preparation for a week of lectures on an entirely new topic. It feels like the first real chance to breathe since this whole intense experience began, a brief moment of calm before module 5 kicks off. Unsurprisingly my mood is somewhat reflective.
We had a presentation in our first module, a key theme of which was perspective. It is only after you've travelled a way down a road that you can pause to take a look over your shoulder to see where you've been, to look at the same place from the opposite direction and with the wisdom and benefit of hindsight.
I don't come from a computer-literate family, in the sense that lots of developers often seem to. In junior school we had a single BBC Micro computer in the classroom that we could take turns playing Podd on, then when the Gameboy came out me and my sister would spend hours playing Tetris and Super Mario Brothers, but I wasn't involved in anything deeper than switching a console on or typing 'Podd can jump'. I didn't have any idea what programming was or how the games were made but I did love breaking things apart and putting them back together, so I ended up becoming a car mechanic.
So when I found myself changing careers many years later, my family (and at first myself) were surprised at my choice but supportive nonetheless. (My amazing mum was still playing with my Mod1 CLI game way after everyone else had drifted out of the room.) Catching up over dinners at the weekend they say "so what are you learning at the moment?". I take a breath and think about how best to describe the stuff I'd just learned that week and wasn't even sure how well I understood it yet.
Explaining something to someone else is a great way to check your own grasp on a subject. It's one of the reasons we write blogs during bootcamp and beyond. I often need to relate what I'm learning to something tangible, which means my conversations with my family go something like this:
"I'm learning about how the internet works; what happens when you press a button on a webpage; how the front and back end interact."
"The what and the what?"
"Frontend and Backend? Well, you know when you come to ours for dinner, you all sit at the table and I'm in the kitchen still, and I usually stick my head through the hatch and ask you if you want any condiments? Well you're at the front end, the fridge is the back end, and I'm whats called a server. When you ask me for mustard, or click on a link to go to a new webpage, that's a request from the frontend, or the 'client'. You requested mustard so I have a look in the fridge, which is a database where all the condiments - or web pages (more specifically all the text, pictures and instructions for how to style them) are stored. Once I find it, I take it back to the hatch, stick my arm through and pass it to you… that's the job of the server - go get the thing the client (browser) asked for, and serve it up to them so it can be looked at on the computer screen. Or in your case, spread onto your steak."
There's also a story about what variables are and how (and why) we pass them, explained in the context of Mum and Dad writing the Christmas cards. I'll save that for another time.
When I realise I'm losing them, I adjust my approach but smile inwardly because I also realise that I'm getting it. The coding journey started for me when I went to my first Girls Code MK meetup just a year ago: I always thought coding was beyond me but within the hour they'd helped me display a picture of kitten, and I even knew how to change the colour of the border. I can't wait to go back there in a few weeks armed with my newfound knowledge, and perhaps use it to help another woman or girl get started on her journey. I might need to work on my stories though. | calier |

What if common knowledge is actually more nuanced, and old familiar things like Double\-checked locking are quite controversial? Examining the code of real projects gives this kind of thought\. In this article, we'll discuss the results of the examination\.
## Introduction
Not so long ago, as part of my work routine related to checking open\-source projects using PVS\-Studio, I checked the newly released 24th version of the well\-known [DBeaver](https://github.com/dbeaver/dbeaver) project\. I was pleasantly surprised by the quality of its code — the fact that developers use static analysis tools doesn't go to waste\. However, I kept digging and found some suspicious code fragments that caught my eye\. They were so conspicuous that I've decided to dedicate an article to each of them\. So, welcome to the first part of the series\.
## Thread\-unsafe programming
### What am I talking about?
Parallel programming has many pitfalls\. Of course, not only in Java, as its evil \(or good :\) \) twin brother C\# can easily make you stumble when using [events](https://pvs-studio.com/en/docs/warnings/v3083/) in parallel scenarios\. Asynchronous and multithreaded errors are often the most difficult to catch\.
Below, we'll look at three types of such errors\. The first one is the non\-atomic change of volatile variables\.
### What's volatile again?
The [documentation](https://docs.oracle.com/javase/tutorial/essential/concurrency/atomic.html) tells what the *volatile* keyword does:
1. It prevents each cache from being used by different threads\. This ensures that changes to a variable are immediately visible to all threads\.
1. It sets a happens\-before relationship between a variable and read/write, thus prohibiting optimizations based on changing the order of operations\.
You can see how this keyword works with a simple example of a thread waiting for a variable to change:
```cpp
private static volatile String str;
public static void main() throws InterruptedException {
new Thread(() -> {
while (str == null) { }
System.out.println(str);
}).start();
Thread.sleep(1);
str = "Hello World!";
}
```
If we remove *volatile*, the loop becomes infinite\. At least in my case\. The result can be highly dependent on the JVM and hardware\.
<spoiler title="How can we see happens-before in action, though?">
If we change the example a bit by adding a bound variable, the happens\-before mechanism becomes clearer:
```cpp
private static String str;
private static volatile boolean flag = false;
public static void main() throws InterruptedException {
new Thread(() -> {
while (!flag) { }
System.out.println(str);
}).start();
Thread.sleep(1);
str = "Hello World!";
flag = true;
}
```
If we had **only** a visibility guarantee, the compiler or processor could reverse the order of assigning operations to the *str* and *flag* variables\. Then we'd have a chance to get into *System\.out\.println\(str\)* when *str* is still *null*\.
However, the happens\-before principle ensures that the write that precedes the write in the volatile variable remains where it's supposed to be\.
</spoiler>
### Race
Even though we have variable visibility, it's certainly not enough to get parallel threads to operate properly:
```cpp
private static volatile int counter = 0;
private static void increment() {
Thread.sleep(1);
counter++;
}
public static void main() {
var threads = Stream.generate(() -> new Thread(Main::increment))
.limit(100)
.toList();
threads.forEach(Thread::start);
while (threads.stream().anyMatch(Thread::isAlive)) {
Thread.yield();
}
System.out.println(counter);
}
```
Such code always returns a number less than 100\. This isn't surprising, since the increment operation isn't atomic, and one thread can squeeze through the other\. This can happen between the operations of taking the old *counter* value and incrementing it by 1\. There can be two fixes, one easier than the other:
<spoiler title="Atomic types">
Let's use special data types that provide a ready\-made interface for working from multiple threads\. In this case, it's *AtomicInteger*\.
```cpp
private static final AtomicInteger counter = new AtomicInteger(0);
private static void increment() {
Thread.sleep(1);
counter.incrementAndGet();
}
```
</spoiler>
<spoiler title="Synchronization">
Let's just add the *synchronized* keyword \(or the *synchronized* block\)\. This ensures that only one thread can perform operations in this method\.
```cpp
private synchronized static void increment() {
Thread.sleep(1);
counter++;
}
```
</spoiler>
### Case study
If you thought that this is basic knowledge and nobody would make the above mistake in real projects, then\.\.\. you're almost right\. I found three fragments in DBeaver where the *volatile* variables of primitive types are handled\. And, as it often happens in real life, the cases aren't so simple\. A dangerous situation may occur in some of them, but for the most part nothing terrible can happen\. Nevertheless, here are these three fragments:
<spoiler title="Counting active operations">
```cpp
public class MultiPageWizardDialog extends .... {
....
private volatile int runningOperations = 0;
....
@Override
public void run(....) {
....
try {
runningOperations++; // <=
ModalContext.run(
runnable,
true,
monitorPart,
getShell().getDisplay()
);
} finally {
runningOperations--; // <=
....
}
}
}
```
The PVS\-Studio warnings:
* [V6074](https://pvs-studio.com/en/docs/warnings/v6074/) Non\-atomic modification of volatile variable\. Inspect 'runningOperations'\. MultiPageWizardDialog\.java\(590\)
* [V6074](https://pvs-studio.com/en/docs/warnings/v6074/) Non\-atomic modification of volatile variable\. Inspect 'runningOperations'\. MultiPageWizardDialog\.java\(593\)
We have two warnings for the price of one, and it's also the only fragment of code where there's a tangible risk\. It would seem that we have a reference case that is almost identical to the artificially created example above\. However, if we take a closer look at the name of the class and the method where everything happens \(*MultiPageWizardDialog* and *run*, respectively\), it becomes clear that we're dealing with UI\. It's very unlikely, if at all possible, that a real race condition can occur here\.
However, if we imagine that the *run* method would be executed simultaneously by multiple threads, the value of *runningOperations* could easily be incorrect\.
</spoiler>
<spoiler title="Progress drawing">
```cpp
private volatile int drawCount = 0;
....
private void showProgress() {
if (loadStartTime == 0) {
return;
}
if (progressOverlay == null) {
....
painListener = e -> {
....
Image image = DBeaverIcons.getImage(
PROGRESS_IMAGES[drawCount % PROGRESS_IMAGES.length]
);
....
};
....
}
drawCount++;
....
}
```
The PVS\-Studio warning:
[V6074](https://pvs-studio.com/en/docs/warnings/v6074/) Non\-atomic modification of volatile variable\. Inspect 'drawCount'\. ProgressLoaderVisualizer\.java\(192\)
Looks like the least dangerous code snippet: *drawCount* is used as a progress image selector, providing a cyclic scrolling index\. Firstly, it seems that the cost of making a mistake in such a code fragment isn't the highest\. Secondly, the very fact of accessing drawing from multiple **parallel** threads sounds questionable\. If the latter assumption is correct, then the *volatile* modifier is redundant here\.
</spoiler>
<spoiler title="Tracking number of initializations">
The analyzer issues a warning for the following code:
```cpp
private volatile int initializedCount = 0;
....
public CompareObjectsExecutor(CompareObjectsSettings settings)
{
....
initializeFinisher = new DBRProgressListener() {
@Override
public void onTaskFinished(IStatus status)
{
if (!status.isOK()) {
initializeError = status;
} else {
initializedCount++;
}
}
};
....
}
```
The PVS\-Studio warning:
[V6074](https://pvs-studio.com/en/docs/warnings/v6074/) Non\-atomic modification of volatile variable\. Inspect 'initializedCount'\. CompareObjectsExecutor\.java\(130\)
This fragment looks more dangerous then the others\. For now, however, we lack any context, so we need to look at where *initializeFinisher* and *initializecCount* are used:
```cpp
this.initializedCount = 0;
for (DBNDatabaseNode node : nodes) {
node.initializeNode(null, initializeFinisher);
....
}
while (initializedCount != nodes.size()) {
Thread.sleep(50);
if (monitor.isCanceled()) {
throw new InterruptedException();
}
....
}
```
This is what we have:
1. the counter is reset;
1. its increment is triggered in *node\.initializeNode*;
1. next, all nodes are checked for being initialized\. Otherwise, the thread sleep occurs for 50 milliseconds\.
It would seem to be a reference case: if two threads increment a counter at the same time, all logic breaks\. Right? No, there are no threads in *node\.initializeNode*\. There's nothing at all in there :\)
```cpp
public boolean initializeNode(
DBRProgressMonitor monitor,
DBRProgressListener onFinish
) throws DBException {
if (onFinish != null) {
onFinish.onTaskFinished(Status.OK_STATUS);
}
return true;
}
```
Anyway, while *DBRProgressListener* is indeed used in parallel scenarios, this isn't the case\. For *initializedCount*, *volatile* just seems redundant, as does the loop that checks the number of initializations\.
</spoiler>
### Unexpected twist
Earlier, we looked at simple examples with primitive types\. Is it enough to mark the reference type field as volatile to ensure similar behavior? Nope\. You can learn more [here](https://wiki.sei.cmu.edu/confluence/display/java/CON50-J.+Do+not+assume+that+declaring+a+reference+volatile+guarantees+safe+publication+of+the+members+of+the+referenced+object)\. By modifying the previous example a bit, we can easily get an infinite loop again:
```cpp
private static class Proxy {
public String str;
}
private static volatile Proxy proxy = new Proxy();
public static void main() throws InterruptedException {
var proxy = Main.proxy;
new Thread(() -> {
while (proxy.str == null) { }
System.out.println(proxy.str);
}).start();
Thread.sleep(1);
proxy.str = "Hello World!";
}
```
One possible fix is to mark the *str* field as volatile, and then everything will work as before\. As for the *proxy* field, there's no point in marking it in any way\.
<spoiler title="Here's the fixed code:">
```cpp
private static class Proxy {
public volatile String str;
}
private static Proxy proxy = new Proxy();
public static void main() throws InterruptedException {
var proxy = TaskRunner.proxy;
new Thread(() -> {
while (proxy.str == null) { }
System.out.println(proxy.str);
}).start();
Thread.sleep(1);
proxy.str = "Hello World!";
}
```
</spoiler>
So, is there a point in marking the reference field as volatile? This is where we finally come to the Double\-checked locking pattern\.
## Double\-checked locking
### Why?
This [pattern](https://java-design-patterns.com/patterns/double-checked-locking/) is used as a high\-performance way to implement lazy initialization in a multi\-thread environment\. The idea is quite simple: a normal check is performed before the "heavy" check in the synchronized block\. The control flow continues only if the requested resource hasn't been created yet\. The implementation seems really simple:
```cpp
public class HolderThreadSafe {
private volatile ResourceClass resource;
public ResourceClass getResource() {
if (resource == null) {
synchronized (this) {
if (resource == null) {
resource = new ResourceClass();
}
}
}
return resource;
}
}
```
The pattern is most often used to create singletons and for delayed initialization of heavy objects\. Is it really that simple, though?
### Is it an anti\-pattern?
This pattern has a rather amusing feature\. [It doesn't work](https://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html)\. At least if you're about the same age as dinosaurs, and you're using a Java version lower than 5\. Stay tuned, though\! In fact, this is a key point in our story :\)
So, what has changed in JDK 5? This is when developers added the *volatile* keyword\. Now, you can immediately catch me out and say that in the example above, the *resource* is marked as volatile\. However, if I were you, I'd take a step back and look at the code\. What exactly is the issue here? Here's the order of actions:
1. *resource* is checked for *null*\. This point can be traversed by multiple threads simultaneously;
1. The synchronized block is accessed\. Only one thread can get in there:
* in the second check, the first thread that did this makes sure that *resource* isn't created yet and then creates it;
1. The other threads that passed the first check access the synchronized block one at a time:
* they see that *resource* is already created, and they go out of there;
1. Everybody's satisfied and happy\.
Why do we need *volatile* if we use synchronization to control the access to the field? The thread value visibility isn't an obstacle here, really, but we have two issues:
* the operation of creating an object **isn't atomic** \(there are no issues with primitive types, except for the 64\-bit ones\);
* by default, both the compiler and lower\-level systems are allowed to **override the operation order**\.
This means that the consequences of such optimizations can be unpredictable\. For example, the compiler can inline the constructor and change the order of field initialization in any way possible\. As a result, an object may be marked as created\. Another thread sees this, starts using it, and finds uninitialized fields there\. The happens\-before principle described above saves us from this\. Thanks to the volatile variables, double\-check locking works since the fifth version of Java\.
### So, is it a pattern after all?
What made me delve so deeply into the theory? It was another analyzer warning that has been issued for the next method of the DBeaver project:
```cpp
private List<DBTTaskRun> runs;
....
private void loadRunsIfNeeded() {
if (runs == null) {
synchronized (this) {
if (runs == null) {
runs = new ArrayList<>(loadRunStatistics());
}
}
}
}
```
[V6082](https://pvs-studio.com/en/docs/warnings/v6082/) Unsafe double\-checked locking\. The field should be declared as volatile\. TaskImpl\.java\(59\), TaskImpl\.java\(317\)
It's funny that the [pattern collection](https://java-design-patterns.com/patterns/double-checked-locking/#applicability) I mentioned earlier lists the following drawback:
> Complex implementation can lead to mistakes, such as incorrect publishing of objects due to memory visibility issues\.
Obviously, this is exactly what happened in this case :\)
Let's return to the question I asked in the theoretical part of the article:
> So, is there a point in marking the reference field as volatile?
Back then, I cheated and deliberately omitted the obvious thing\. When we change an object field, we don't touch the variable containing the object reference in any way\. However, when the variable is **overwritten**, all information specified in that section becomes relevant again\. So, even with the aforementioned limitations \(a volatile field doesn't guarantee the safe publication for the members of the object it references\), there are use cases, and this is one of them\.
### Or is it, though?\!
It seems that the fix in this case is obvious: just mark the *runs* list as the volatile variable\. This resolves the issue\. However, I suggest that you remember the purpose of the pattern:
> The Double\-Checked Locking pattern aims to reduce the overhead of acquiring a lock by first testing the locking criterion \(the 'lock hint'\) without actually acquiring the lock\. Only if the locking criterion check indicates that locking is necessary does the actual locking logic proceed\.
So, we have a pattern that's designed for optimization\. What could be the issue here? Here's a hint: do you remember my comment about dinosaurs? :\)
This pattern was born a **long** time ago, when *synchronized* methods were very slow\. Today, both JVM and hardware performance have advanced significantly\. So, the risk of such errors makes it expensive to use this \(micro\)optimization\. If we talk only about singletons, initializing them as a class field is sufficient for the thread safety:
```cpp
class Holder {
static SomeSingleton singleton = new SomeSingleton();
}
```
In other cases, we can just use synchronized methods, unless everything else is already optimized\.
By the way, since I've mentioned C\# before, I'll do it again\. Funny enough, the exact same issue exists there too, as we've [written about before](https://pvs-studio.com/en/blog/posts/csharp/0715/)\.
### Another unexpected twist
Should we use synchronized methods? What if the developers are already doing this? In that case, the *volatile* field would simply be redundant\. It's used in 20 code fragments, let's look at a random three:
<spoiler title="One">
```cpp
void addNewRun(@NotNull DBTTaskRun taskRun) {
synchronized (this) {
loadRunsIfNeeded();
runs.add(taskRun);
while (runs.size() > MAX_RUNS_IN_STATS) {
runs.remove(0);
}
flushRunStatistics(runs);
}
TaskRegistry.getInstance().notifyTaskListeners(....);
}
```
Okay, we immediately found a fragment where it's used four times, but there's also a *synchronized* block here\.\.\.
</spoiler>
<spoiler title="Two">
```cpp
private void loadRunsIfNeeded() {
if (runs == null) {
synchronized (this) {
if (runs == null) {
runs = new ArrayList<>(loadRunStatistics());
}
}
}
}
```
Here we have three more for the price of one and *synchronized* again\. Have I really just been messing with your heads all this time?
</spoiler>
<spoiler title="Three">
```cpp
@Override
public void cleanRunStatistics() {
Path statsFolder = getTaskStatsFolder(false);
if (Files.exists(statsFolder)) {
....
}
if (runs != null) {
runs.clear();
}
flushRunStatistics(List.of());
TaskRegistry.getInstance().notifyTaskListeners(....);
}
```
Gotcha\! If we follow the uses of this method, there's no synchronization anywhere above\. So, we've found what we've been looking for\. By the way, this fragment isn't the only one\.
</spoiler>
What was the need for this performance if I could just show you a snippet without synchronization? This is just another [potential vulnerability](https://pvs-studio.com/en/docs/warnings/v6102/)\. Its presence alone can cause a race condition in addition to making possible the consequences of a double\-check locking error\.
So, it'll take a little more effort to fix that code fragment, because while we were analyzing one bug, another bug was found\.
## Conclusion
I hope you enjoyed diving into the wonderful world of parallel programming pitfalls with me\. Many people claim that if you've ever had to use volatile variables or the double\-checked locking pattern, you've already done something wrong\. Or you're an expert and you knew exactly what you were doing :\)
Still, I think this note sums up the content of the whole article pretty well: the rabbit hole is deep, indeed\. At least it's deep enough to be twice as careful when dealing with the topic of the article\.

1,877,921 | Abstract Syntax Tree In TypeScript | Hello everyone, السلام عليكم و رحمة الله و بركاته Abstract Syntax Trees (ASTs) are a fundamental... | 0 | 2024-06-05T11:08:33 | https://dev.to/bilelsalemdev/abstract-syntax-tree-in-typescript-25ap | programming, typescript, javascript, webdev | Hello everyone, السلام عليكم و رحمة الله و بركاته
Abstract Syntax Trees (ASTs) are a fundamental concept in computer science, particularly in the realms of programming languages and compilers. While ASTs are not exclusive to TypeScript, they are pervasive across various programming languages and play a crucial role in many aspects of software development.
### Importance of ASTs
1. **Compiler Infrastructure**: ASTs serve as an intermediary representation of code between its textual form and machine-executable instructions. Compilers and interpreters use ASTs to analyze, transform, and generate code during the compilation process.
2. **Static Analysis**: ASTs enable static analysis tools to inspect code for potential errors, security vulnerabilities, or code smells without executing it. Tools like linters, code formatters, and static analyzers leverage ASTs to provide insights into code quality and maintainability.
3. **Language Features**: ASTs facilitate the implementation of advanced language features such as type inference, pattern matching, and syntactic sugar. By manipulating ASTs, language designers can introduce new constructs and behaviors into programming languages.
### ASTs in TypeScript
While ASTs are not specific to TypeScript, they are integral to the TypeScript compiler's operation and ecosystem. TypeScript's compiler (tsc) parses TypeScript code into an AST representation before type-checking, emitting JavaScript, or performing other compilation tasks. ASTs in TypeScript capture the syntactic and semantic structure of TypeScript code, including type annotations, generics, and other TypeScript-specific features.
### How ASTs are Used in TypeScript
1. **Type Checking**: TypeScript's type checker traverses the AST to perform type inference, type checking, and type resolution. AST nodes corresponding to variable declarations, function calls, and type annotations are analyzed to ensure type safety and correctness.
2. **Code Transformation**: TypeScript's compiler API allows developers to programmatically manipulate ASTs to transform TypeScript code. Custom transformers can be applied to modify AST nodes, enabling tasks such as code optimization, polyfilling, or code generation.
3. **Tooling Support**: IDEs and code editors leverage ASTs to provide rich language services for TypeScript developers. Features like code completion, refactoring, and error highlighting rely on ASTs to understand code context and provide accurate feedback to developers.
4. **TypeScript Ecosystem**: Various tools and libraries within the TypeScript ecosystem utilize ASTs to enhance developer productivity and enable advanced tooling capabilities. For example, tools like ts-migrate and tslint rely on ASTs to automate code migrations and enforce coding standards.
### Example
Suppose we have the following TypeScript code:
```typescript
function greet(name: string): void {
console.log("Hello, " + name + "!");
}
greet("Mohamed");
```
We can use TypeScript's Compiler API to parse this code into an AST and traverse the tree to inspect its structure.
Here's how you can do it programmatically:
```typescript
import * as ts from "typescript";
// TypeScript code to parse
const code = `
function greet(name: string): void {
console.log("Hello, " + name + "!");
}
greet("Mohamed");
`;
// Parse the TypeScript code into an AST
const sourceFile = ts.createSourceFile(
"example.ts",
code,
ts.ScriptTarget.Latest
);
// Recursive function to traverse the AST
function traverse(node: ts.Node, depth = 0) {
console.log(
`${" ".repeat(depth * 2)}${ts.SyntaxKind[node.kind]} - ${node.getText()}`
);
ts.forEachChild(node, (childNode) => traverse(childNode, depth + 1));
}
// Start traversing the AST from the source file
traverse(sourceFile);
```
When you run this code, it will output the AST structure of the TypeScript code:
```
SourceFile -
FunctionDeclaration - function greet(name: string): void {
console.log("Hello, " + name + "!");
}
Identifier - greet
Parameter - name: string
Identifier - name
StringKeyword - string
VoidKeyword - void
Block - {
ExpressionStatement - console.log("Hello, " + name + "!");
CallExpression - console.log("Hello, " + name + "!")
PropertyAccessExpression - console.log
Identifier - console
Identifier - log
StringLiteral - "Hello, "
BinaryExpression - name + "!"
Identifier - name
StringLiteral - "!"
ExpressionStatement - greet("Mohamed")
CallExpression - greet("Mohamed")
Identifier - greet
StringLiteral - "Mohamed"
```
In this output:
- Each line represents a node in the AST.
- The indentation indicates the parent-child relationship between nodes.
- The text after the node type (e.g., `FunctionDeclaration`, `Identifier`) represents the actual TypeScript code corresponding to that node.
This example demonstrates how TypeScript's Compiler API can be used to parse TypeScript code into an AST and traverse the tree to inspect its structure programmatically.
### Conclusion
In summary, Abstract Syntax Trees (ASTs) are a fundamental concept in programming language theory and compiler construction. While not specific to TypeScript, ASTs play a crucial role in the TypeScript ecosystem, enabling type checking, code transformation, and advanced tooling capabilities. Understanding ASTs is essential for developers seeking to leverage TypeScript's features effectively and contribute to the TypeScript ecosystem's growth and evolution. | bilelsalemdev |

1,877,918 | Collection Interface - Quick Overview | The Collection interface is a part of the Java Collections Framework, which provides a unified... | 0 | 2024-06-05T11:03:29 | https://dev.to/dhanush9952/collection-interface-quick-overview-hgc | java, programming | The Collection interface is a part of the Java Collections Framework, which provides a unified architecture for storing and manipulating collections of objects. It is the root interface in the hierarchy and provides basic methods for adding, removing, and inspecting elements in a collection.
_[Download image here](https://drive.google.com/file/d/1a9Ry9Fb8Ptw-lNAas2_NxFAna5QUbOF6/view?usp=sharing)_
The Collection interface has several subinterfaces that specify different types of collections, each with specific characteristics:
**List:**An ordered collection (also known as a sequence). Lists can contain duplicate elements. Some common implementations are ArrayList, LinkedList, and Vector.
**Set:**A collection that cannot contain duplicate elements. This is implemented by classes like HashSet, LinkedHashSet, and TreeSet.
**Queue:** A collection designed for holding elements prior to processing. Queues typically, but do not necessarily, order elements in a FIFO (first-in-first-out) manner. Examples include PriorityQueue and LinkedList (which also implements List).
**Deque:** A double-ended queue that allows elements to be added or removed from both ends. Examples include ArrayDeque and LinkedList.
## List Interface
**ArrayList:**
- Provides random access to elements.
- Fast iteration and size operations.
- Inefficient for inserts and deletes, except at the end of the list.
- Not synchronized.
```
List<String> arrayList = new ArrayList<>();
arrayList.add("Apple");
arrayList.add("Banana");
```
**LinkedList:**
- Doubly-linked list implementation.
- Efficient for inserts and deletes.
- Implements both List and Deque interfaces.
- Not synchronized.
```
List<String> linkedList = new LinkedList<>();
linkedList.add("Apple");
linkedList.add("Banana");
```
**Vector:**
- Synchronized and thread-safe.
- Generally slower due to synchronization overhead.
- Uses a dynamic array to store elements.
- Support Enumeration(Legacy interface)
```
List<String> vector = new Vector<>();
vector.add("Apple");
vector.add("Banana");
```
## Set Interface
**HashSet:**
- Backed by a hash table.
- Stores elements in HashTable based on the order of hashcode.
- No guarantees on the hashcode order of elements.(So its Random order)
- Allows null elements.
- Does not allow duplicates
```
Set<String> hashSet = new HashSet<>();
hashSet.add("Apple");
hashSet.add("Banana");
```
**LinkedHashSet:**
- Maintains a linked list of the entries in the set, in the order in which they were inserted.
- Provides predictable iteration order.
- Does not allow duplicates
```
Set<String> linkedHashSet = new LinkedHashSet<>();
linkedHashSet.add("Apple");
linkedHashSet.add("Banana");
```
**TreeSet:**
- Sorted according to the natural ordering of its elements or by a comparator provided at set creation time.
- Sorted in ascending order By default.
- Implements NavigableSet.
- Does not allow duplicates and NULL(because by default it sorts elements in ascending order using comparator<T>. So, if there are NULL values in comparing it throws exception).
```
Set<String> treeSet = new TreeSet<>();
treeSet.add("Apple");
treeSet.add("Banana");
```
## Queue Interface
**PriorityQueue:**
- An unbounded priority queue based on a priority heap.
- Orders elements according to their natural ordering or by a comparator provided at queue construction time.
```
Queue<String> priorityQueue = new PriorityQueue<>();
priorityQueue.add("Apple");
priorityQueue.add("Banana");
```
**LinkedList:**
- Implements both List and Deque interfaces.
- Can be used as a queue by utilizing methods like offer, poll, and peek.
```
Queue<String> linkedQueue = new LinkedList<>();
linkedQueue.offer("Apple");
linkedQueue.offer("Banana");
```
## Deque Interface
**ArrayDeque:**
- Resizable-array implementation of the Deque interface.
- Not thread-safe.
- Faster than LinkedList for adding and removing elements at both ends.
```
Deque<String> arrayDeque = new ArrayDeque<>();
arrayDeque.addFirst("Apple");
arrayDeque.addLast("Banana");
```
**LinkedList:**
- Doubly-linked list implementation of the Deque interface.
```
Deque<String> linkedDeque = new LinkedList<>();
linkedDeque.addFirst("Apple");
linkedDeque.addLast("Banana");
```
The Collection interface and its various implementations provide a robust framework for working with groups of objects in Java. Understanding the differences between the various collection types, their implementations, and the scenarios for their use is crucial for effective and efficient programming.

Aqui somos defensores fevorosos do Home Office, sendo o presencial só para nos reúnirmos pra conversar e comer um churrasco. Claro, temos nosso escritório presencial para quem preferir ou quiser ir trabalhar presencialmente, fica **a escolha da pessoa**, não é e jamais será obrigatório.
## Camera ligada ou desligada
Aqui seguimos esse formato:
- Nas daily calls, plannings, conversas tecnicas, fica a sua escolha ligar ou não, é 100% opcional, já que o foco não é "em você", mas sim no problema e solução que estão sendo discutidas
- Nas calls 1-1, feedback, onde o foco é conversar mesmo sobre você, suas opniões, experiências, expectativas, etc, é obrigatório ligar a webcam, porque o foco é em você
## Code Review
Sem frescura bicho: Nome de variavel tem q estar descritivel baseado no escopo dela. Sem comentário de "troca de contactList pra listContact", "Faz essa função aqui receber um parametro em cada linha ao inves de todos na mesma linha", sem essas frescuras.
Code Review é pra ver se:
- A implementação segue a especificação
- O código não tem falhas de segurança
- O código está seguindo a arquitetura do projeto
- O código não tem problemas de performance
Se não estiver descrito nessa lista acima, então não faz parte do code review e não pode bloquear um PR.
## Scrum / Agile
Scrum, story points, user story, planning poker, scrum master, são todos termos **PROIBIDOS** aqui. Trabalhamos com prazos, com tasks, com features e com especificação tecnica.
Nosso workflow é melhor explicado [nesse artigo](https://dev.to/henriqueleite42/the-right-development-flow-better-than-agile-871), caso você tenha curiosidade.
## Microsoft
Sempre evitamos qualquer coisa da Microsoft: Abominamos Teams, Outlook, Windows, Azure, etc.
As únicas coisas que se salvam no meio disso (pelo menos por enquanto) são o GitHub e o VSCode. Todas as outras ferramentas da Microsoft nós **jamais** usaremos.
Todas as nossas documentações oficiais, configurações para rodar os projetos, comandos, etc, são todos feitos e pensados **exclusivamente para Linux**, e é esperado que nosso desenvolvedores saibam trabalhar com linux, tendo pelo menos um [dual boot](https://www.youtube.com/watch?v=6D6L9Wml1oY&ab_channel=Diolinux).
## Qualidade (de verdade!)
Foco sempre em qualidade, performance, desafios e coisas bem feitas. Aqui sempre deixamos tudo bem especificado, bem documentado e bem executado. Entendemos o que fazemos, porque fazemos e debatemos sobre podemos melhorar ainda mais.
Aqui muuuuuuito raramente teremos casos onde "faz de qualquer jeito pra entregar" ou "Como faço isso? Não encontro os detalhes no ticket".
## Alinhamento de objetivos
Sabemos que cada pessoa tem seus próprios objetivos, suas proprias metas e seus próprios sonhos, e que nem sempre eles estão ligados a empresa, o que está corretíssimo! Temos que dar prioridade pra fámilia, amigos, saúde e coisas que são importantes pra gente.
Mesmo tendo objetivos que não sejam 100% alinhados, gostamos de manter pelo menos alguns deles combinados:
- Aprimoramento: Sempre focar em melhorar, aprender mais, buscar conhecimento, fazer o melhor possivel nas condições que temos.
- Comunicação saudavel: Ter discussões amigaveis, sempre focando em construir o melhor produto possivel para nossos usuários.
- Passar conhecimento: Ensinar aquilo que você sabe para seus colegas, ajuda-los a melhorar, compartilhar conhecimento.
Tendo esses objetivos como importantes, então você e a Anuntech vão se dar muito bem! 😄

Many build tools such as Cargo, Pip, NPM were not designed to protect from them ([NPM example](https://wildwolf.name/secure-way-run-npm-ci/), [Cargo-related discussion](https://internals.rust-lang.org/t/about-supply-chain-attacks/14038)). At the same time maintainers' tools such as Nix, Guix, RPM and DEB build systems successfully mitigate such attacks. These tools precisely control what files are downloaded over the network before the build starts and prohibit any network access during the build phase itself. In this article we introduce a tool called [Cijail](https://github.com/staex-io/cijail) that allows you to adopt similar rules for developers' build systems such as Cargo, Pip, NPM. This tool is based on Linux [Seccomp](https://man7.org/linux/man-pages/man2/seccomp.2.html), can be run inside CI/CD pipelines, and does not require superuser privileges. It protects from data exfiltration over DNS via deep packet inspection effectively limiting the damage supply chain attacks can cause. The tool is open source and written in Rust.

## <a name="why"></a>Why protect from supply chain attacks?
Supply chain attacks are become popular with introduction of developers' tools that manage project's dependencies. In contrast to maintainers' tools they do not block network access during build phase, and hackers use this seemingly minor breach to exfiltrate secrets by bundling malicious scripts with the dependency and executing these scripts during build phase. It takes only one popular dependency to be compromised to run these scripts on a multitude of developers' computers and CI/CD pipelines and steal private keys. This is unlikely event but the damage it may cause is catastrophic: private keys might give access to a cryptowallet (on a developer's machine), to a server via SSH, to a static website via cloud upload endpoint etc. From our perspective protecting from them by default is like using the seat belt: no one expects a car crash when one uses a seat belt, but expects the belt to save one's life in an unlikely catastrophic situation.
## <a name="what"></a>What is a supply chain attack?
Supply chain attack starts with hacker getting access to a repository of a popular software package. The hacker can use social engineering, zero-day vulnerabilities in operating systems or breaches in repository management system itself. Usually two-factor authentication can protect from the attack on this phase.
If the hacker was able to get access to the repository, he or she proceeds with making a malicious commit or (most likely) making a new release archive that contains malicious code. Usually signed commits and signed releases/packages/archives protect from the attack on this phase.
Then the attacker waits until dependent software packages download new release of the breached dependency and execute the malicious code in their CI/CD pipelines or on the developers' computers. In order to exfiltrate the secrets the hacker would obscure the traffic as DNS for example and setup a DNS server to collect the secrets.
## <a name="how"></a>How the data is exfiltrated over DNS?
Data exfiltration over DNS works as follows. A malicious actors sets up a DNS server for his/her domain. Then it encodes secrets as subdomains of this domain and eventually the DNS lookup request reaches the hacker's DNS server via other perfectly secure and legit publicly available DNS servers. This exfiltration uses DNS as a side channel. This is one of many side channels that hackers might use (the other popular one being ICMP protocol).
Conveniently DNS traffic is not blocked anywhere because other software uses DNS. One way to protect from this attack is to either allow to resolve only certain domains via deep packet inspection or block Internet access altogether. Maintainers' tools use the latter while Cijail adopts the former approach because developers' tools were not designed to block the traffic during build phase.
## <a name="how-to"></a>How we can protect ourselves from supply chain attacks?
Cijail protects from supply chain attacks via whitelisting domain names, IP addresses and ports as well as URLS that a script is allowed to access. This is implemented using Seccomp and MITM HTTPS proxy server. Cijail launches the supplied command in a child process with Seccomp jail and `SECCOMP_RET_USER_NOTIF` flag. Simultaneously the control process is launched that receives notifications from the jailed process and decides if the resource can be accessed via `SECCOMP_IOCTL_NOTIF_SEND` flag. Finally, a MITM HTTPS proxy is launched as the third process. This process decrypts all HTTPS requests to check that the corresponding URL is allowed. For MITM HTTPS proxy to work the CA SSL certificate is automatically installed in the operating system as trusted.
```bash
# no traffic is allowed
🌊 cijail dig staex.io @1.1.1.1
[Sun Apr 04 17:28:22 2024] cijail: deny connect 1.1.1.1:53
# DNS request (connection to DNS server is allowed whereas name resolution is not)
🌊 env CIJAIL_ENDPOINTS='1.1.1.1:53' cijail dig staex.io @1.1.1.1
[Sun Apr 04 17:28:22 2024] cijail: allow connect 1.1.1.1:53
[Sun Apr 04 17:28:22 2024] cijail: deny sendmmsg staex.io
# DNS request and name resolution is allowed
🌊 env CIJAIL_ENDPOINTS='1.1.1.1:53 staex.io' cijail dig staex.io @1.1.1.1
[Sun Apr 04 17:28:22 2024] cijail: allow connect 1.1.1.1:53
[Sun Apr 04 17:28:22 2024] cijail: allow sendmmsg staex.io
... dig output ...
```
### <a name="example-cargo"></a>Example: Cargo + Github (Cijail itself)
We tried to use Cijail for building itself. In order to use Cijail in your Github Actions you need to add the following line to your Dockerfile.
```dockerfile
COPY --from=ghcr.io/staex-io/cijail:0.6.8 / /usr/local
```
Then you have to prepend cijail to every command in every step because Github Actions do not respect Docker's `ENTRYPOINT`. Then all you need to do is to add `CIJAIL_ENDPOINTS` environment variable with the list of allowed URLS and other endpoints. The resulting workflow specification for Cijail looks like the following.
```yaml
variables:
CIJAIL_ENDPOINTS: |
https://github.com/lyz-code/yamlfix/ # git
https://pypi.org/simple/ # pip
https://files.pythonhosted.org/packages/ # pip
https://static.crates.io/crates/ # cargo
https://index.crates.io/ # cargo
https://uploads.github.com/repos/staex-io/cijail/releases/ # github
https://api.github.com/repos/staex-io/cijail/releases # github
steps:
- name: Lint
run: cijail ./ci/build.sh
```
### <a name="example-npm"></a>Example: NPM + Gitlab (static web site)
For Gitlab the approach is similar. This time you might consider adding `ENTRYPOINT ["/usr/local/bin/cijail"]` to your `Dockerfile` to not prepend `cijail` to every command in your pipeline. The resulting workflow specification for a static web site looks like the following.
```yaml
CIJAIL_ENDPOINTS: |
https://registry.npmjs.org/ # npm
https://github.com/lyz-code/yamlfix/ # git
https://pypi.org/simple/ # pip
https://files.pythonhosted.org/packages/ # pip
9.9.9.9:53 # rsync
staex.io:22 # rsync
```
### <a name="caveat-cargo-deny"></a>Caveat: cargo-deny via HTTPS proxy
One particular problem that we encountered is the fact that some programs bundle trusted root CA certificates in their binaries. This is the case for cargo-deny. This tool uses webpki-roots crate that bundles root CA certificates as byte arrays directly in the cargo-deny binary. It is impossible to add Cijail's root certificate to such a program. The current workaround is to run cargo-deny without Cijail.
```bash
# our MITM proxy failed to trick cargo-deny :-(
🌊 cijail cargo deny check
[ERROR] error trying to connect: invalid peer certificate: UnknownIssuer
# a workaround
🌊 cijail cargo deny check --disable-fetch || true # a warm-up (download dependencies)
🌊 cargo deny check # run without cijail 😮
```
### <a name="caveat-npm"></a>Caveat: NPM via HTTPS proxy
Another problem comes from the fact that NPM usage behind HTTPS proxy is not as reliable as without it. In some cases it creates thousands of connections to download a few dependencies. The workaround that we found is to specify `maxsocket=1` in NPM's configuration.
```bash
# 1000+ connections for 340 dependencies?
🌊 cijail npm install
[Fri May 24 07:02:13 2024] cijail: allow connect 127.0.0.1:39317
[Fri May 24 07:02:13 2024] cijail: allow connect 127.0.0.1:39317
[Fri May 24 07:02:13 2024] cijail: allow connect 127.0.0.1:39317
... the message repeats 1000+ times
npm ERR! code ECONNREFUSED
# a workaround
🌊 npm config set maxsockets 1
```
## <a name="conclusion"></a>Conclusion
To summarize, most CI/CD pipelines are vulnerable to data exfiltration via DNS because developers' tools like Cargo, NPM and PIP do not block network access during build phase in contrast to maintainers' tools like Nix, Guix, RPM and DEB build systems that do.
The best way to protect from any data exfiltration is to split building the package into download and build phase. During download phase the dependencies are downloaded but no scripts are executed and no packages are built. During build phase the scripts are executed and the packages are built, but the network access is disabled. This simple technique will protect from any type of data exfiltration without the need for deep packet inspection.
The major problem with implementing such a split in developers' tools is the fact that it might break some packages. Another problem is that blocking network access in a Docker container might require additional privileges that are not present by default. Below is the example of how to do this manually for NPM and Cargo.
```bash
# cargo example
🌊 cargo download # only download dependencies
🌊 unshare -rn cargo build # build packages and run scripts without network access (will not work in a Docker container)
# npm example
🌊 npm clean-install --ignore-scripts # only download dependencies
🌊 unshare -rn npm rebuild # build packages and run scripts without network access (will not work in a Docker container)
```

If not, you can read all about it in my [application journey.](https://dev.to/ndutared/my-outreachy-application-journey-28m1)
In this post, I share my progress this far.
## Week 1
Week 1 was a roller coaster for me. I spent some time refreshing my Python and Django knowledge, but honestly there was still a lot to learn.
I spent the first week going through some tutorials, as I had already done the project set up during the contribution phase.
The tutorials were okay, and I started to understand the project somewhat.
Truth be told, OpenStack is a mammoth.
### Task 1
I had my first meeting and it was apparent that we would need Angular to work with Glance, as there had been a transition. I have never written any Angular in my life, so that was quite a punch in the stomach.
So what next?
My mentors advised to start with Python/Django, so now the focus moved to Cinder(the initial plan was to work with Glance).
So, we set up the first task. And I realized that I had not even come across Cinder code even after spending some time going through the code.
My mentors were kind enough to go point me in the right direction.
The first task was fixing a really small bug.
### Blockers
I was excited that my mentors wanted me to start small. My mentor had fixed the bug in like five minutes. I was like, okay, maybe it'll take me an hour tops.
When I actually sat down to write the code, I was quite lost. It took me quite a while to find the right files.
I then spent hours going through volumes code. I went through the classes, trying to understand what each was doing, and noting the ones responsible for the bug I was going to fix.
### Murky waters
Somewhere along the way, I realized that the volumes code was not 100% mapped to Django file structure.
I couldn't find the templates responsible for that particular code. And after many hours I was in very muddy waters. I couldn't just figure out the connection between some files.
I went to bed without any sense of accomplishment.
### Asking for help
I however was honest about not making some connections, and my mentor sent more resources my way.
### Out of the Woods
It helps to work on code when my mind is settled. So I read through my mentors resources. One of them was a tutorial I already gone through.
I stepped back and tried to apply my experience getting lost with the resources. I was also able to narrow down to the specific code where the bug was.
## Submitting my review
It took me a while to remember the steps I needed to take. I had copied and pasted a doc with some steps, but I couldn't trace its source.
I finally found it, and decided to write down the [submitting a review steps](https://github.com/AgnesNM/OpenStack-Horizon/blob/main/review.md) for my future self, and hopefully, for someone else.
## Forging onward
For now, there's still a long way to go, and I hope for many good days, without getting too lost in the woods.
## Speaking OpenStack if you are coming from AWS
I've found it helpful to think about OpenStack in terms of AWS, since that's what I understand a little better. So here is "AWS-translated OpenStack"
There's much more, of course, these are just some main concepts.

These metrics... | 0 | 2024-06-05T10:56:24 | https://dev.to/kammarianand/evaluation-metrics-machine-learning-models-lg5 | python, machinelearning, ai, datascience | Evaluation metrics are crucial in assessing the performance of machine learning models. These metrics help us understand how well our models are performing and where they might need improvement. In this post, we'll dive into evaluation metrics for two primary types of machine learning tasks: regression and classification. We'll also provide code examples using scikit-learn and its datasets.
## What are Evaluation Metrics?
Evaluation metrics are quantitative measures used to evaluate the performance of machine learning models. They provide insights into how well the model is making predictions and help in comparing different models to select the best one for a given task.
## Regression vs. Classification
* Regression: This involves predicting a continuous value. Examples include predicting house prices, stock prices, or temperature.
* Classification: This involves predicting a discrete label. Examples include classifying emails as spam or not spam, identifying the species of an iris flower, or detecting fraudulent transactions.
## Regression Evaluation Metrics
**1. Mean Absolute Error (MAE)**
The Mean Absolute Error is the average of the absolute differences between predicted and actual values.
Formula : `MAE = (1/n) * Σ|y_i - ŷ_i|`
```python
from sklearn.metrics import mean_absolute_error
from sklearn.datasets import load_boston
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
# Load dataset
data = load_boston()
X, y = data.data, data.target
# Split data
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# Train model
model = LinearRegression()
model.fit(X_train, y_train)
# Predict
y_pred = model.predict(X_test)
# Evaluate
mae = mean_absolute_error(y_test, y_pred)
print(f'Mean Absolute Error: {mae}')
```
**2. Mean Squared Error (MSE)**
The Mean Squared Error is the average of the squared differences between predicted and actual values.
Formula: `MSE = (1/n) * Σ(y_i - ŷ_i)^2`
```python
from sklearn.metrics import mean_squared_error
# Evaluate
mse = mean_squared_error(y_test, y_pred)
print(f'Mean Squared Error: {mse}')
```
**3. Root Mean Squared Error (RMSE)**
The Root Mean Squared Error is the square root of the average of the squared differences between predicted and actual values.
Formula: `RMSE = √((1/n) * Σ(y_i - ŷ_i)^2)`
```python
import numpy as np
# Evaluate
rmse = np.sqrt(mse)
print(f'Root Mean Squared Error: {rmse}')
```
**4. R-squared (R²)**
R-squared is the proportion of the variance in the dependent variable that is predictable from the independent variables.
Formula:`R² = 1 - (Σ(y_i - ŷ_i)^2 / Σ(y_i - ȳ)^2)`
```python
from sklearn.metrics import r2_score
# Evaluate
r2 = r2_score(y_test, y_pred)
print(f'R-squared: {r2}')
```
## Classification Evaluation Metrics
**1. Accuracy**
Accuracy is the ratio of correctly predicted instances to the total instances.
Formula:`Accuracy = (Number of correct predictions) / (Total number of predictions)`
```python
from sklearn.metrics import accuracy_score
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
# Load dataset
data = load_iris()
X, y = data.data, data.target
# Split data
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# Train model
model = RandomForestClassifier()
model.fit(X_train, y_train)
# Predict
y_pred = model.predict(X_test)
# Evaluate
accuracy = accuracy_score(y_test, y_pred)
print(f'Accuracy: {accuracy}')
```
**2. Precision**
Precision is the ratio of correctly predicted positive observations to the total predicted positives.
Formula:`Accuracy = (Number of correct predictions) / (Total number of predictions)`
```python
from sklearn.metrics import precision_score
# Evaluate
precision = precision_score(y_test, y_pred, average='weighted')
print(f'Precision: {precision}')
```
**3. Recall**
Recall is the ratio of correctly predicted positive observations to the all observations in actual class.
Formula:`Recall = TP / (TP + FN)`
```python
from sklearn.metrics import recall_score
# Evaluate
recall = recall_score(y_test, y_pred, average='weighted')
print(f'Recall: {recall}')
```
**4. F1 Score**
The F1 Score is the weighted average of Precision and Recall.
Formula:`F1 Score = 2 * (Precision * Recall) / (Precision + Recall)`
```python
from sklearn.metrics import f1_score
# Evaluate
f1 = f1_score(y_test, y_pred, average='weighted')
print(f'F1 Score: {f1}')
```
**5. Confusion Matrix**
The confusion matrix is a summary of prediction results on a classification problem. The correct and incorrect predictions are summarized with count values and broken down by each class.
Code Example:
```python
from sklearn.metrics import confusion_matrix
import seaborn as sns
import matplotlib.pyplot as plt
# Evaluate
cm = confusion_matrix(y_test, y_pred)
# Plot
sns.heatmap(cm, annot=True, fmt='d', cmap='Blues')
plt.xlabel('Predicted')
plt.ylabel('Actual')
plt.show()
```

That's why robust testing frameworks have become so important for web developers. Among the plethora of available tools, Cypress and Playwright have emerged as two of the most popular choices for automating end-to-end testing.
In this Cypress versus Playwright comparison guide, we'll explore the strengths and weaknesses of the two tools, their features, and their differences.
Cypress or Playwright? Find out which best suits your needs!
## Introduction to Cypress and Playwright
Cypress and Playwright are both open-source, JavaScript-based, popular end-to-end testing frameworks for browser automation. While the two libraries have certain key differences, they share some features and most use cases.
Time to get a better understanding of the two web browser automation frameworks.
## What Is Cypress?
[Cypress](https://www.cypress.io/) is a modern, frontend, end-to-end testing framework built for web applications. It allows you to write and maintain efficient tests, and can run tests written in JavaScript directly in the browser. In other words, it can test and interact with anything running in a browser. The target audience for this technology is developers or QA engineers who build web apps using modern JavaScript frameworks.
The types of tests supported by Cypress are:
- **End-to-end tests:** Validate the entire flow related to real-world user case scenarios.
- **Component tests:** Verify the functionality of single UI components in isolation.
- **Integration tests:** Ensure that different modules or components work together seamlessly.
- **Unit tests:** Test the behavior of individual functions or methods in isolation.
These tests are nothing more than JavaScript files that follow the [Mocha](https://mochajs.org/) BDD syntax and use [Chai](https://www.chaijs.com/) as the assertion engine. Cypress comes with a local GUI tool built into Electron that makes it easier to set up, run, and debug tests. Alternatively, you can use Cypress CLI to launch tests headlessly. To write the test logic, you will need a JavaScript IDE.
Here are some stats on Cypress (up-to-date at the time of writing):
- **GitHub stars:** 45k+
- **npm weekly downloads:** 4.8m+
- **Contributors:** 480+ individuals
- **First release:** September 10, 2017
## What Is Playwright?
[Playwright](https://playwright.dev/) is an end-to-end testing framework developed by Microsoft and available in multiple programming languages. Its focus is on cross-browser testing, using Chromium as the default browser. To perform the test logic on a Chromium-based browser, it controls and instructs a browser instance to perform desired actions via the DevTools Protocol.
Thanks to its intuitive API and many available features, [Playwright has gained a lot of traction](https://blog.appsignal.com/2023/07/12/an-introduction-to-playwright-for-nodejs.html) in the IT community, even though it has only been around since 2020. Web developers now use it for both testing and other browser automation tasks, such as web scraping.
Playwright supports end-to-end testing, integration testing, unit testing, and even visual regression testing. That involves automatically detecting and reporting any visual differences or discrepancies between two versions of the same web application. Playwright's default recommended programming language is TypeScript, which means that test scripts are usually `.ts` files.
As of writing, some key statistics for Playwright include:
- **GitHub stars:** 62k+
- **npm weekly downloads:** 4.6m+
- **Contributors:** 500+
- **First release:** January 31, 2020
## What Playwright and Cypress Have to Offer
A Cypress versus Playwright comparison article wouldn't be complete without a list of features offered by the two tools.
### Cypress: Main Features
These are the most important [Cypress features](https://docs.cypress.io/guides/overview/why-cypress#Features):
- **Batteries included:** The framework offers everything needed to write, run, and debug tests effectively without having to install external dependencies.
- **Cross-browser testing:** You can run tests locally in Firefox and all Chrome-family browsers (including Chrome, Chromium, Brave, Edge, and Electron).
- **Simple debugging:** Debug directly in Developer Tools thanks to the [`.debug()`](https://docs.cypress.io/guides/guides/debugging#Using-debug) method. Cypress also provides readable errors and stack traces specifically designed to facilitate debugging.
- **Automatic waits:** Cypress automatically waits for a fixed timeout for commands and assertions to be successful before moving on. That allows you to avoid adding explicit sleep instructions to your tests, which makes them flaky.
- **Time traveling:** Cypress takes snapshots as your tests run, adding them to the [command log](https://docs.cypress.io/guides/core-concepts/cypress-app#Command-Log) so that you can understand what happens at each step.
- **Network traffic control:** Stub local network traffic without changing your server's logic.
- **Screenshots and videos:** Configure your tests to produce screenshots or video recordings when run from the CLI.
- **Clock, time, and date control:** Modify your application's time or manipulate `Date` objects, and `setTimeout()`, `clearTimeout()`, `setInterval()`, and `clearInterval()` functions.
- **Function spies:** Make sure that a function is called with the right arguments or a certain number of times. You can also verify that a function returns the expected value and is called in the right context.
- **Extensible via plugins:** Cypress can be extended via plugins developed by the community.
- **Cypress Cloud:** An online platform that enhances Cypress test automation capabilities by providing parallel test execution, smart orchestration, flake detection in CI pipelines, video replays, and more.
### Playwright: Main Features
These are some of the most useful features offered by Playwright:
- **Cross-browser support:** Playwright allows testing across multiple browsers, including Chrome, Firefox, WebKit, Edge, and all Chromium-based browsers.
- **Available in multiple programming languages:** The default language supported by Playwright is TypeScript. It also supports Python, Java, C#, and JavaScript.
- **Parallel test execution:** By default, [Playwright runs tests in parallel](https://playwright.dev/docs/test-parallel) to improve test suite performance and reduce overall execution time. For even greater parallelization, you can also scale test execution on multiple machines.
- **Visual Studio Code extension for debugging:** A dedicated extension to debug your tests right in Visual Studio Code, see error messages, set breakpoints, and step through your test logic.
- **Videos, screenshots, and visual comparisons:** Record videos of test execution, generate screenshots, and visually compare screenshots to conduct visual regression testing.
- **Automatic test generation:** Let the tool generate tests for you as you perform actions in the browser.
- **Different result reporters:** Set up the reporter that best suits your needs to produce test results as a list, in HTML, as an image, in JSON, and more.
- **Network interception:** Stub and manipulate network requests to simulate different scenarios without having to modify your server.
- **Device emulation:** Run testing without the need for physical devices thanks to [emulated devices](https://playwright.dev/docs/emulation), including mobile devices.
- **Automatic waiting:** Playwright automatically waits for UI elements to be ready, eliminating the need for manual wait commands and reducing flakiness.
- **Full browser interaction:** Interact with the browser to open new tabs, navigate between pages, and handle context switches. Also, you can [mock experimental browser APIs](https://playwright.dev/docs/mock-browser-apis).
## Cypress vs. Playwright: Similarities and Differences
Let's now analyze what the two tools have in common and where they differ.
### Similar Aspects
Playwright and Cypress are both open-source frameworks designed for end-to-end testing through browser automation. Their goal is to validate the functionality of a web application on various browsers. To achieve that, the two tools offer rich APIs to simulate user interactions, including clicking buttons, filling out forms, and navigating between pages.
In addition, both tools focus on developer experience by providing an intuitive API for writing and maintaining test scripts. Quality-of-life features like automatic waiting improves test reliability by eliminating the need for boilerplate code. Plus, request stubs make it easier to mock and manipulate AJAX requests without having to touch the server. When it comes to setting up the test suite, both tools offer guided procedures to get you started in minutes. At the same time, configuring the frameworks and browsers to get the desired result can take a while.
The two libraries also offer extensive debugging capabilities, including inspection of test execution, screenshot capabilities, and video recording. To run tests on CI, they support launching browsers in [headless mode](https://developer.chrome.com/blog/headless-chrome), without the GUI.
### Main Differences
An effective way to see the Playwright versus Cypress differences is to look at their syntax. Suppose you want to submit a login form with "myusername" and "mypassword" credentials and verify that it redirects users as expected. This is how you can do it in Cypress:
```javascript
describe("Login form test", () => {
it("should log in successfully", () => {
// visit the login page
cy.visit("/login");
// type the username into input field
cy.get("#username").type("myusername");
// type the password into input field
cy.get("#password").type("mypassword");
// submit the form
cy.get("form").submit();
// verify that the app redirect you to the dashboard page
cy.url().should("include", "/dashboard");
});
});
```
Here's how you can achieve that in Playwright:
```javascript
import { test, expect } from "@playwright/test";
describe("Login form test", () => {
it("should log in successfully", async () => {
// visit the login page
await page.goto("http://example.com/login");
// type the username into input field
await page.fill("#username", "myusername");
// type the password into input field
await page.fill("#password", "mypassword");
// submit the form
await page.click('form [type="submit"]');
// verify the app redirect you to the dashboard page
expect(page.url()).toContain("/dashboard");
});
});
```
Although both frameworks are based on Mocha's syntax for structuring tests, their APIs are quite different. This difference in syntax impacts readability and ease of test writing, depending on developer preference. Note that Playwright's API is richer because it also allows you to control browser tabs, which isn't supported by Cypress.
Another significant difference is in their parallelization capabilities. Playwright natively supports parallel test execution out of the box. On the contrary, Cypress doesn't support parallelization by default. In this case, developers need to rely on plugins like [`cypress-parallel`](https://www.npmjs.com/package/cypress-parallel).
While Cypress can be expanded with plugins, Playwright comes with more built-in features. At the same time, [Cypress Cloud](https://www.cypress.io/cloud) rounds out the offerings with interesting additional functionality. Unfortunately, not all of them are free.
## Which to Choose — Playwright or Cypress?
Whether you use Playwright and Cypress depends on a project's specific requirements and context. There's no one-size-fits-all answer, as each framework has strengths and weaknesses.
For use cases where simplicity is paramount, Cypress may be the best choice. Its focus on developer experience and ease of debugging makes it well-suited for teams with limited experience in test automation or small projects with simpler testing requirements.
In contrast, Playwright shines in scenarios that require cross-browser testing or complex automation. Similarly, it's great if you are unsure which language to write your tests in. Its flexibility makes it preferable for larger projects or those with specific requirements not fully covered by Cypress's capabilities, such as visual regression testing. However, Cypress is better for other scenarios, such as component testing.
Let's summarize some of the pros and cons of each tool.
### Cypress: Pros and Cons
**👍 Pros**
- Automatic waits for commands and assertions.
- Captures snapshots during test execution.
- Plugin support.
**👎 Cons**
- Available only in JavaScript.
- No support for multi-tabs.
- Can't control two browsers at the same time.
### Playwright: Pros and Cons
**👍 Pros**
- Cross-browser and cross-language support.
- A lot of features, such as reporting, automatic test generation, and VS Code debugging.
- Out-of-the-box parallel execution.
**👎 Cons**
- Can't be extended via plugins.
- Still relatively new.
- No support for function spies.

## Setting Up Your Development Environment
To initiate the development of a [real-time chat application using Laravel Reverb and Vue 3](https://qirolab.com/posts/building-real-time-chat-applications-with-laravel-reverb-and-vue-3), start by installing Laravel 11 with the Composer command:
```
composer create-project laravel/laravel:^11.0 laravel-reverb-react-chat
cd laravel-reverb-react-chat/
```
Following the installation, configure Laravel Reverb by executing the command:
```
php artisan install:broadcasting
```
This command facilitates the installation of Laravel Reverb and builds the necessary Node dependencies for broadcasting. Ensure that the environment variables specific to Reverb are correctly set in the `.env` file, including `BROADCAST_CONNECTION=reverb`, `REVERB_APP_ID`, `REVERB_APP_KEY`, and others.
Next, proceed to configure the `reverb.php` and `broadcasting.php` files located in the config directory. These configurations are crucial for establishing a connection to Reverb, where the Reverb "application" credentials play a pivotal role in verifying client-server requests.
For the frontend setup with Vue 3, begin by installing Vue CLI globally using:
```
npm install -g @vue/cli
```
Then create a new Vue project with vue create client. Navigate to the client directory and start the development server with `npm run serve`. Integrate Vue 3 into your Laravel project by updating the `src/App.vue` file with your desired components and layouts, and make API requests to the Laravel backend using Axios or similar HTTP client libraries.
Lastly, incorporate Tailwind CSS for styling by installing it via npm and configuring it in your project to enhance the UI of your chat application 10.
## Building the Backend
### Creating Models, Migrations, and Controllers
To establish the foundation of the backend, one starts by generating a model along with its corresponding migration and controller using the command:
```
php artisan make:model Message -mcr
```
This command efficiently sets up the necessary files, enabling the creation of the messages database table and the establishment of CRUD operations within the controller.
### Defining Routes and Blade Views
Next, the routes are defined in the `web.php` file, ensuring that they are correctly set up to handle incoming requests. For instance, routes for different settings pages are meticulously mapped to their respective controllers 18. Concurrently, Blade views are created and linked to these routes, allowing for dynamic content rendering based on the passed route parameters.
### Handling Real-Time Broadcasting with Laravel Reverb
Finally, to handle real-time broadcasting, Laravel Reverb is integrated by setting up the necessary broadcasting configurations and creating events that trigger real-time updates. Commands like `php artisan install:broadcasting` are used to configure Laravel Reverb. Events are then defined to broadcast updates to the client, ensuring seamless real-time communication within the chat application.
## Developing the Frontend
### Designing the Chat Interface with Vue 3
In the development of the chat interface using Vue 3, the App.vue component orchestrates the core functionalities such as fetching chat messages and managing user interactions. The design integrates a Messages component that displays chat messages in a list, where each message includes the sender's name, avatar, and text. This setup ensures that the latest messages are immediately visible through the use of a bottomRef, which Vue's onUpdate lifecycle function automatically scrolls to upon message arrival.
### Using Vue Components for Real-Time Interactivity
To enhance real-time interactivity, the Input component in Vue allows users to input text and send messages. This component does not send messages directly but triggers a callback when the send button is clicked, which then communicates with the backend to process the message. The seamless integration of components like `ChatMessages.vue` within the Vue application facilitates efficient data handling and user interaction, leveraging the Axios library for asynchronous data transfer.
Managing Chat Messages and Notifications
Effective management of chat messages and notifications is crucial for a responsive user experience. Utilizing WebSockets, the frontend can receive notifications pushed from the server, addressing concerns about performance and connection management. Additionally, the Messages component is designed to differentiate messages sent by the user from those received, enhancing the clarity and usability of the chat interface.
## Testing and Running Your Chat Application
###Starting the Laravel Event Broadcasting Server
To initiate the Laravel event broadcasting, utilize the command `php artisan reverb:start` to activate the WebSocket server, ensuring real-time communication capabilities. This setup is crucial for managing live interactions within the chat application.
### Compiling Assets with Laravel Vite
During development, compile your assets using Vite by running `npm run build`. This command assembles the frontend resources, integrating them seamlessly with Laravel through the Vite configuration. Ensure that the Vite development server is correctly configured to handle HTTPS connections if required.
### Performing End-to-End Testing
For comprehensive testing, execute end-to-end tests by setting up a testing environment that mimics production settings. Utilize the php artisan serve command to run the application and verify its functionality by logging in as different users and interacting within the chat. This process helps in identifying and resolving any issues before the final deployment.
## Conclusion
Throughout this article, we’ve navigated the intricate process of building a [real-time chat application using Laravel Reverb](https://www.youtube.com/watch?v=8ykxcM0-3Yg) and Vue 3, highlighting the strengths and synergies of these technologies.

1,877,907 | Sachin Dev Duggal - Future Employment and AI: Moving Beyond Technological Displacement | AI has transformed how we work, leading to a complete overhaul of the employment landscape. Besides... | 0 | 2024-06-05T10:44:54 | https://dev.to/triptivermaa01/sachin-dev-duggal-future-employment-and-ai-moving-beyond-technological-displacement-lf6 | ai, beginners | AI has transformed how we work, leading to a complete overhaul of the employment landscape. Besides AI displacing some jobs, it also creates new ones and enhances current ones. As AI evolves, we must understand its implications for tomorrow's workforce and how to transition from technological replacement to a more teaming workplace environment.
**Automation and Job Displacement**
The significant impact of AI on employment is automation. The fear of losing jobs has emerged with artificial intelligence (AI) systems that have become more capable of "thinking," like humans, being able to perform tasks previously performed by human beings. In manufacturing, the customer service industry, data entry, and other routine automated tasks are changing the available job types. Nevertheless, it must be borne in mind that while AI may replace some jobs, there will also be new career opportunities demanding skills in AI development, data analysis, and machine learning. [Sachin Dev Duggal](https://zeenews.india.com/india/exploring-innovations-in-fintech-app-development-with-builder-ai-2745981.html) the co-founder of Builder.ai, artificial intelligence (AI) will augment human potential while also leading to a change in employment positions that are more focused on creativity and innovation. Rather than being afraid that AI would cause job displacement, he advises embracing it as a tool for empowerment and teamwork.
**Augmentation and Collaboration**
Rather than replacing humans entirely, AI is often used to augment human abilities and promote collaboration through machines. AI systems can process and interpret massive volumes of data, providing practical knowledge that people can use to make better decisions. Various fields, such as healthcare finance or marketing, are being transformed using AI-enhanced human intelligence. The globally acclaimed entrepreneur Sachin Dev Duggal, believes AI has the potential to revolutionize industries by improving procedures and streamlining undertakings, and optimizing operations. For example, in the finance landscape, financial decision-making can get support from machines in finance; and strategies can be optimized using this technology like ML coupled with AI. The automation and optimization brought by AI allows employees to manage complex activities involving emotional intelligence, critical thinking, and creativity, thereby leading to greater efficiency and productivity within the evolving workforce.
**Reskilling and Upskilling**
AI's impact on the job market shows that continuous learning and adaptability are necessary. People must evolve their skills as roles change and new skills are demanded to remain competitive. This necessitates improving current know-how in line with technology (upskilling) and acquiring new ones for different positions (reskilling). Organizations, educational institutions, and governments have developed programs, workshops, and online platforms to assist employees with AI, data analysis, programming, and digital literacy training.
**Valuing Creative Contributions**
[Sachin Dev Duggal](https://www.northernirelandworld.com/arts-and-culture/ai-is-threatening-150000-irish-jobs-set-to-be-displaced-within-the-decade-what-experts-say-4653026)'s vision revolves around creative contributions rather than routine tasks. Such a method understands that AI can automate repetitive chores, leaving time for human resources; subsequently, they can engage in tangible activities requiring creativity, critical thinking, and emotional intelligence. We could encourage this uniqueness in people to cultivate a culture within organizations where workers feel valuable and essential parts of an AI-driven labor market that changes over time.
**Broader Implications for the Future Workforce**
The future workforce must be flexible, resilient, and knowledgeable about AI technologies. With AI emerging into an intelligent automation era where trivial duties are automated to enable people to concentrate on more meaningful jobs, we should no longer work like we used to but develop new skills, enabling us to fit today's changing employment world. Workers must upskill themselves proactively or reskill themselves to retain relevance in an AI-dominated economy. By emphasizing growth at the personal level and flexibility, the audience should feel confident enough when it comes to dealing with forthcoming job markets.
AI is changing the job market by automating routine tasks while giving space for creativity, critical thinking, and emotional intelligence. For one's success, one must be adaptable, resilient, and well-versed in cutting-edge technologies related to AI. Serial entrepreneurs like Sachin Duggal have championed shaping work towards valuing creative contributions and have provided training and support for the workforce to leverage AI opportunities. | triptivermaa01 |

1,877,904 | What is MANUAL TESTING its DRAWBACKS and BENEFITS. | Manual testing is a fundamental process in software testing where testers manually execute test cases... | 0 | 2024-06-05T10:39:46 | https://dev.to/s1eb0d54/what-is-manual-testing-its-drawbacks-and-benefits-4830 | Manual testing is a fundamental process in software testing where testers manually execute test cases without the aid of automation tools. It involves a human tester interacting with the software application, exploring its features, and verifying its behavior against predefined test scenarios. Manual testing is essential for ensuring the quality and functionality of software products and is often complemented by automated testing methodologies. Let's delve into the benefits and drawbacks of manual testing with examples and diagrams.
### Benefits of Manual Testing:
1. **Human Insight and Intuition:**
- Human testers can leverage their intuition and domain knowledge to identify potential issues that automated tests might overlook. For instance, a tester might detect a usability flaw that impacts the overall user experience, which automated tests may not capture.
- *Example:* During manual testing of a web application, a tester notices that a critical button is not responsive on certain mobile devices due to a design oversight.
2. **Flexibility and Adaptability:**
- Manual testing allows testers to adapt quickly to changes in requirements or features. Testers can explore the software organically, responding to real-time feedback and adjusting their testing approach accordingly.
- *Example:* A tester performs ad-hoc testing on a newly implemented feature, uncovering unexpected behavior and providing valuable feedback to the development team.
3. **Exploratory Testing:**
- Manual testing enables exploratory testing, where testers explore the software dynamically without predefined test cases. This approach can uncover complex issues and edge cases that automated tests may not cover.
- *Example:* A tester explores various combinations of user inputs in a search functionality, discovering a bug that occurs only under specific search criteria.
### Drawbacks of Manual Testing:
1. **Time and Resource Intensiveness:**
- Manual testing can be time-consuming and labor-intensive, especially for large or complex applications. Testers must repeat test cases across different environments and configurations manually, leading to longer testing cycles.
- *Example:* In a manual regression testing phase for a web application, testers spend significant time retesting each functionality to ensure no regressions occur after a software update.
2. **Human Error and Variability:**
- Manual testing is susceptible to human error, and testing results may vary between different testers. This variability can lead to inconsistencies in testing coverage and potentially overlook critical defects.
- *Example:* Two different testers may interpret the same test case differently, leading to inconsistent testing outcomes and potentially missing critical defects.
3. **Scalability Challenges:**
- As the size and complexity of the software project increase, manual testing becomes less scalable. It may not be feasible to perform comprehensive testing manually within reasonable timeframes.
- *Example:* In a large-scale enterprise application with hundreds of features, manually testing every functionality for each release becomes impractical and resource-intensive.
### Summary:
Manual testing offers unique advantages such as human insight, flexibility, and exploratory testing capabilities. However, it also presents challenges in terms of time, scalability, and human error. To mitigate these drawbacks, organizations often adopt a balanced approach by combining manual testing with automated testing techniques. By leveraging the strengths of both methodologies, software development teams can ensure comprehensive test coverage while optimizing testing efforts and resources. | s1eb0d54 | |
1,877,903 | Understanding Type Casting in Java: Importance, Usage, and Necessity | Introduction In Java programming, data types are fundamental, ranging from primitive types... | 0 | 2024-06-05T10:39:20 | https://dev.to/fullstackjava/understanding-type-casting-in-java-importance-usage-and-necessity-p8f | java, webdev, programming, tutorial |
### Introduction
In Java programming, data types are fundamental, ranging from primitive types like integers and floats to complex types like objects and arrays. Often, there is a need to convert a variable from one type to another to ensure compatibility and accuracy. This process is known as type casting. Type casting in Java enhances flexibility, efficiency, and precision. This blog will explore what type casting is in Java, its importance, how it is used, and why it is needed.
### What is Type Casting in Java?
Type casting in Java is the process of converting a variable from one data type to another. This can be done implicitly by the compiler or explicitly by the programmer. Java supports two main types of type casting:
1. **Implicit Type Casting (Widening Conversion):** The compiler automatically converts a smaller data type to a larger data type.
2. **Explicit Type Casting (Narrowing Conversion):** The programmer manually converts a larger data type to a smaller data type using casting operators.
### Importance of Type Casting
Type casting in Java is essential for several reasons:
1. **Data Compatibility:** Ensures that data types are compatible with various operations and methods.
2. **Precision and Accuracy:** Maintains the precision and accuracy of data during arithmetic operations.
3. **Resource Management:** Efficiently manages memory and processing resources.
4. **Interoperability:** Facilitates data exchange between different systems or components.
### Usage of Type Casting in Java
#### Implicit Type Casting (Widening Conversion)
Implicit type casting happens automatically and involves converting a smaller data type to a larger one. For example:
```java
int a = 10;
double b = a; // 'a' is implicitly cast to double
System.out.println(b); // Output: 10.0
```
In this example, the integer `a` is implicitly converted to a double to match the data type of `b`.
#### Explicit Type Casting (Narrowing Conversion)
Explicit type casting requires the programmer to specify the conversion. This is common when converting from a larger data type to a smaller one. For example:
```java
double a = 9.8;
int b = (int)a; // Explicitly cast double to int
System.out.println(b); // Output: 9
```
Here, `a` is explicitly cast to an integer, truncating the decimal part.
### Type Casting with Objects
Java also supports type casting with objects, particularly when dealing with inheritance and interfaces. This involves converting between superclass and subclass types or between interface and implementing class types.
#### Upcasting
Upcasting is converting a subclass type to a superclass type. This is implicit:
```java
class Animal {}
class Dog extends Animal {}
Dog d = new Dog();
Animal a = d; // Upcasting Dog to Animal
```
#### Downcasting
Downcasting is converting a superclass type to a subclass type. This requires explicit casting:
```java
Animal a = new Dog();
Dog d = (Dog)a; // Downcasting Animal to Dog
```
### Need for Type Casting
1. **Avoiding Errors:** Prevents type errors during execution, ensuring data compatibility.
2. **Enhanced Functionality:** Enables type-specific operations, enhancing functionality.
3. **Data Manipulation:** Essential for transforming and processing data effectively.
4. **Interfacing with APIs and Libraries:** Ensures data type compatibility when working with external APIs or libraries.
### Best Practices for Type Casting in Java
1. **Use Explicit Casting When Necessary:** Avoid ambiguity and make the code more readable by using explicit casting.
2. **Check for Data Loss:** Be mindful of potential data loss when casting between types with different precision or range.
3. **Validate Data:** Always validate data before casting to ensure it is in a format that can be safely converted.
4. **Understand Language-Specific Behavior:** Familiarize yourself with Java’s specific casting rules and behavior.
### Examples of Type Casting in Java
#### Implicit Casting
```java
short s = 100;
int i = s; // Implicit casting from short to int
long l = i; // Implicit casting from int to long
float f = l; // Implicit casting from long to float
double d = f; // Implicit casting from float to double
System.out.println("short: " + s);
System.out.println("int: " + i);
System.out.println("long: " + l);
System.out.println("float: " + f);
System.out.println("double: " + d);
```
#### Explicit Casting
```java
double d = 100.04;
long l = (long)d; // Explicit casting from double to long
int i = (int)l; // Explicit casting from long to int
System.out.println("double: " + d);
System.out.println("long: " + l);
System.out.println("int: " + i);
```
### Conclusion
Type casting is a powerful feature in Java that ensures data compatibility, precision, and efficient resource management. By understanding and utilizing type casting effectively, programmers can write more robust and versatile code. Whether working with simple data conversions or complex object casting, mastering type casting is essential for any Java developer.
By leveraging type casting appropriately, you can handle data accurately, efficiently, and without errors, making it a vital skill in your programming toolkit. | fullstackjava |

Little (or not so little) pessimist in me also want to say "We can also always do worse!"
But do not listen to him! Let's see how we might make this better.
### Best code is the one you do not write!
You can actually totally remove Backend service and have client make all the calls, problem is that you will have your API keys exposed and there is no other way to authenticate api calls as of now for Open AI and Eleven Labs.
### Cache 💵 because all cool kids are doing it!
Cache! We are making call to fetch our CMS data on each request, this might not be needed as our data for CV does not change often if at all. This can also save costs because in the example I am using Hygrpah which has a free tier but can eventually reach its free quota.
### Maybe if we use **_please_** word more in our prompt? 🤓 (do not fail to note sarcasm in the quote)
Better prompting, if you explore LlamaIndex there are ways how one can make their promoting yield better and more accurate responses. You can create custom Prompt template, or make have clear instructions about how system should behave.
## Outro 👋
This was a lot, please feel free to look at the code base and ask any question you might have.
I would also welcome any improvements that one is willing to share.
And lastly, if you make all the way, thank you so much I hope you had some fun and learn something in the process.

1,877,811 | Digital Shield: How to Protect Yourself in the World of Information Threats | Hi all! Quite often I go online and don’t even suspect that danger could be lurking at literally... | 0 | 2024-06-05T09:15:06 | https://dev.to/gerda/digital-shield-how-to-protect-yourself-in-the-world-of-information-threats-3okg | Hi all! Quite often I go online and don’t even suspect that danger could be lurking at literally every step. Today I will try to explain to you the basics of information security.
Information security today plays a huge role in the life of every person. After all, we store a lot of personal information on the Internet: from financial data to personal photos. And it can become the target of attacks from cybercriminals who are ready to use this information to harm us.
In order to protect yourself and your data, you must follow a few simple but very important rules. First, use strong passwords to access your online accounts. Remember that "123456" or "qwerty" are not secure passwords!
Secondly, pay attention to the addresses of the sites you go to. Check SSL certificates to make sure you're on a secure site and not a fake one designed to steal your data.
Also keep an eye on software updates on your devices. Often, developers release patches to fix discovered vulnerabilities in the system, and it is necessary to install them in order to be protected from new types of attacks.
It is also important to remember to back up your data regularly. Back up your information so that in the event of loss or a cyber attack, you can quickly restore your data. This will give you an additional level of protection and confidence in the safety of your valuable files and documents.
Don't forget to use antivirus software and firewalls. These tools will help protect your devices from malware and hacker attacks. Update your antivirus software regularly so it can detect and block new threats that appear online.
Educating yourself and your loved ones about cybersecurity is also important. Communicate with children and older relatives about what information should be avoided online, what threats can lurk on the Internet, and how to properly respond to suspicious situations. This will help not only you, but also those around you to be more secure online.
Remember that information security is an ongoing process that requires attention. Follow best internet security practices and you can reduce your risk of becoming a victim of cybercrime. Do not neglect this issue, because your security and confidentiality of information should remain a priority.
And of course, do not share personal information with suspicious people on the Internet. Do not respond to suspicious emails or follow suspicious links - this may lead to the theft of your data or infection of your device with viruses.
Information security is an integral part of our digital life. Keep this in mind and follow these simple rules to protect yourself and your data from cyber threats. Don't ignore security issues - your personal information is worth much more than it seems at first glance.

We have three parts: Fetch Relevant... | 27,606 | 2024-06-05T10:34:15 | https://dev.to/nmitic/making-your-cv-talk-how-to-combine-open-ai-text-stream-response-with-eleven-lab-web-socket-streaming-in-typescript-n50 | elevenlabs, openai, typescript | Let's briefly refer back to this part of our system design.
We have three parts:
1. Fetch Relevant CMS data
2. Fetch stream from Open AI
3. Feed Web socket audio stream api with text stream from Open AI
Eleven Labs uses web socket api to enable for audio stream, open AI uses rest api to return text stream.
What is important here to achieve is that we do not want to wait for the open AI response before we can start streaming audio from eleven labs.
> This means we need a way to send first chunk of Open AI stream as soon as possible to eleven labs.
But we have a problem, Open AI or any other LLM api (Groq as well) returns chunks which do not represent any meaningful words which eleven labs requires in order to work as intended.
This means that we need to buffer chunks into words from Open AI and only when we have our first word buffered we send a message to web socket of Eleven Labs and start streaming audio.
For this purpose I wrote `textChunker` which is TS version of Python example Eleven Labs has in their docs. 🔗🔗🔗 [Click here to see Python version ](https://elevenlabs.io/docs/api-reference/websockets#example-voice-streaming-using-elevenlabs-and-openai)

1. Get buffered chunk
2. Write to response object
And it looks like this.
```
onChunkReceived: (chunk) => {
const buffer = Buffer.from(chunk, "base64");
res.write(buffer);
},
```
I will talk more about onChunkReceived method in the next section. Long story short, it it accepts a callback with chunk that come from web socket api. This is implementation details of how to work with Eleven Labs API.
Each time web socket sends an event that chunk is received it will write to response object and return chunk to the client.
This is the simplest way to combine express js with web socket api.

1,877,734 | Making your CV talk 🤖 How to send text stream from Express JS? | Here we have stream coming from Open AI. We need to read chunks and stream it back as soon as chunk... | 27,606 | 2024-06-05T10:33:59 | https://dev.to/nmitic/making-your-cv-talk-how-to-send-text-stream-from-express-js-1d3 | express, streaming, node | Here we have stream coming from Open AI. We need to read chunks and stream it back as soon as chunk is ready. In a way we are streaming a stream.
One can make a case that this is not needed, however I am doing this in order to hide API keys for Groq, Open AI and Hygraph headless CMS. As I do not want them to be exposed to the client.
Route handler for `/api/ask` route:
```
export const route = async (req: Request, res: Response) => {
const { question } = req.query;
if (typeof question !== "string") {
return res
.status(400)
.send(`Client error: question query not type of string`);
}
try {
const answerSource = await getAnswerSource();
const answerChunks = await getAnswerChunks(answerSource, question, false);
for await (const chunk of answerChunks) {
console.log(chunk.response);
if (req.closed) {
res.end();
return;
}
res.write(chunk.response);
}
} catch (error) {
return res.status(500).send(`Server error: ${error}`);
}
res.end();
};
```
Let's dissect it a bit:
```
const answerSource = await getAnswerSource();
```
Here we are getting all our relevant data, CV, blog posts plus any pages you would like your AI clone to be aware of.
```
const answerChunks = await getAnswerChunks(answerSource, question, false);
```
Here we are feeding out LLM with our custom data and question. And getting stream back as a response.
```
for await (const chunk of answerChunks) {
console.log(chunk.response);
if (req.closed) {
res.end();
return;
}
res.write(chunk.response);
}
```
Here we simply iterate over chunks and make sure we close connection in case client do so as well.
And our streamception is done! 🎏

1,877,733 | Making your CV talk 🤖 How to have Open AI api answer based on your custom data? | I used https://ts.llamaindex.ai/. As somebody who is just starting out with generative AI, I have... | 27,606 | 2024-06-05T10:33:55 | https://dev.to/nmitic/making-your-cv-talk-how-to-have-open-ai-api-answer-based-on-your-custom-data-4ie4 | openai, customdata | I used https://ts.llamaindex.ai/.
As somebody who is just starting out with generative AI, I have found LlamaIndex to be of a huge help.
They help you cut the corners and reduce need for a deep understanding about how LLM work in order to be productive. Which is something I need as a beginner.
One thing to note is that TS version tend to be unstable in terms of API at the time of writing, versions keep introducing new functions and classes signatures and their docs sometimes fails to follow up.
So be patient, I believe TS version will reach maturity soon. They are doing a great job.
Code is rather simple:
```
export const getAnswerChunks = async (
source: string,
question: string,
useGroq: boolean = false
) => {
if (useGroq) {
// Update llm to use Groq
Settings.llm = new Groq({
apiKey: process.env.GROQ_API_KEY,
model: "llama3-8b-8192",
});
}
// Create Document object
const document = new Document({
text: `Nikola Mitic - life story: ${JSON.stringify(source)}`,
});
// Create storage from local file
const storageContext = await storageContextFromDefaults({
persistDir: "./index-storage",
});
// Split text and create embeddings. Store them in a VectorStoreIndex
const index = await VectorStoreIndex.fromDocuments([document], {
storageContext,
});
// gets retriever
const retriever = index.asRetriever({ similarityTopK: 5 });
const chatEngine = new ContextChatEngine({
retriever,
chatModel: Settings.llm,
});
// Get stream chunks
const chunks = await chatEngine.chat({
message: `
You are Nikola Mitic AI clone.
You answer the question as if you are Nikola Mitic.
If question is related to work experience, the correct and complete answer can be found under "nikola_mitic_resume_cv_work_experience"
Bellow id the question:
-------------------------------------------------
${question}
-------------------------------------------------
`,
stream: true,
});
return chunks;
};
```
Let's dissect it a bit:
```
if (useGroq) {
// Update llm to use Groq
Settings.llm = new Groq({
apiKey: process.env.GROQ_API_KEY,
model: "llama3-8b-8192",
});
}
```
Here we are adding a flag that will instruct LlamaIndex to use Groq instead of Open AI which is its default settings. Important to note, regardless of Groq usage, we will still need to use Open AI as Groq does offer embeddings models at the time of writing.
However, Groq API seems to be free as of time of this writing, so one can save a lot.
```
// Create Document object
const document = new Document({
text: `Nikola Mitic - life story: ${JSON.stringify(source)}`,
});
// Create storage from local file
const storageContext = await storageContextFromDefaults({
persistDir: "./index-storage",
});
// Split text and create embeddings. Store them in a VectorStoreIndex
const index = await VectorStoreIndex.fromDocuments([document], {
storageContext,
});
// gets retriever
const retriever = index.asRetriever({ similarityTopK: 5 });
```
Here we are creating our document, creating file system storage context for future retrievals.
Creating our vector store and finally retriever. Please note, playing with `similarityTopK` is important here, it is choice between faster response time and more accurate and content rich full answer.
```
const chatEngine = new ContextChatEngine({
retriever,
chatModel: Settings.llm,
});
// Get stream chunks
const chunks = await chatEngine.chat({
message: `
You are Nikola Mitic AI clone.
You answer the question as if you are Nikola Mitic.
If question is related to work experience, the correct and complete answer can be found under "nikola_mitic_resume_cv_work_experience"
Bellow id the question:
-------------------------------------------------
${question}
-------------------------------------------------
`,
stream: true,
});
```
Finally we make use of LlamaIndex chat interface and construct our prompt. You should play with the prompt, I find out this to be very tricky and results very on which LLM is used.
So have fun with it. ✌️

1,877,727 | Making your CV talk 🤖 Explaining the concept and system design👨💻 | Explaining the concept (in non technical terms) Here are where things finally gets to be... | 0 | 2024-06-05T10:33:50 | https://dev.to/nmitic/making-your-cv-talk-explaining-the-concept-and-system-design-33no | softwareengineering, systemdesign | ### Explaining the concept (in non technical terms)
Here are where things finally gets to be more interesting. To make it very simple to understand I will simplify concept so that we can understand it easier and build on top of it later.
Imagine we have a house with 3 floors, each flow unlocks something new.
1. First flor is called Question floor.
2. Second flor knowledge flor.
3. Third flor Speech flor.
### Question floor ❓
Now let's imagine you enter the first flow. Here you can ask your question. **This represents our web page with chat and audio interface.**
### Knowledge floor 📚
You can take a piece of paper and write you question down. But you want an answer. Getting the answer requires knowledge. Problem is, you do not have time to wait. You tried to enter next flow, knowledge room but it takes so long for you to find an answer write it down and go back to you question room, where you can ask more.
So instead, you bring a friend with you, this friend will take your question look for the answer and as _soon_ it has something that _might_ be an answer to you question he will write it down, on multiple papers, each containing part of the answer, and will give it to you so that you can read one by one and not wait until he write the complete answer.
**Knowledge floor is our Interview AI backend service leveraging Open AI (or Groq or any other LLM service of your choice) being aware of our CV data**.
But wait there is one more flow to unlock! Speech floor. This is because you got tired of reading and talking, you want to ask using questions using your voice and you want answer to be voice as well!
### Speech floor 🗣️
Speech floor is where we have our cloned voice! And all it does is take paper with text written on it and start talking whatever is written. And here, just as in knowledge floor, you want to hear the voice as soon as answer is available!
So you have a third friend who is very loud and can speak in volume that you from the first floor can hear. You friend in knowledge room is now giving papers with chunked answer (text stream in tech term) to your friend in speech room, who start reading them to you part by part (paper by paper) as soon as he gets the first paper. (Audio stream in tech terms) **Speech floor is our Eleven Labs voice clone API.**
## System design - How it all comes together?
[Click here for link to diagram](https://excalidraw.com/#json=XobHjKxjVPrno51o-_MY5,GLe_8Eh1fNbsZOVN9gwVQA)
Ok back to our world of ones and zeros. You can get yourself familiar with our system design using the diagram above.
It looks more complicated than it actually is.
We have 5 main components:
1. Client - Next JS
2. Express JS - server with two routes (/api/talk and api/ask)
3. Headless CMS - Hygraph
4. Open AI API (and Groq API as a second choice for reduced costs)
5. Eleven AI api
The name of the game here is STREAM. 🏄♂️
Express JS always return stream of either text chunks or audio chunks. Both Eleven AI and Open AI support streaming which are in a way just proxied through our custom Express JS server.
One tricky part here is how to feed Eleven Lab web socket with stream from Open AI. We will talk about that in the following chapters.
Here is what happens when user type question in chat interface:
1. Client makes an API call to Backend service via `/api/ask` path
2. Backend service makes a call to headless CMS to get latest data
3. Once CMS data is returned Backend makes another request towards Open AI to get answer in a form of stream.
4. and finally Backend returns stream to the client.
Here is what happens when user type ask question using audio interface:
1. Client converts audio into text using client speech recognitions API.
2. Client makes an API call to Backend service via `/api/talk` path.
3. Backend service makes a call to headless CMS to get latest data.
4. Once CMS data is returned Backend makes another request towards Open AI to get answer in a form of stream.
5. As soon as first chunk of streamed data is returned, backend will create a buffer, represents array of words needed for Elevent labs web socket api.
6. Backend makes request towards Eleven Labs web socket API as soon as first buffered word is ready.
7. Eleven Labs returns audio stream to Backend.
8. Backend returns the stream and exposes a route which can be played in client using audio web api.
I won't go in to details about each part of the system and how to implement, however there are certain problems you will face regardless of tech stack of choice, and would like to share how I went about solving them.

1,877,723 | Making your CV talk 🤖 Product mindset first 🧠 Defining features | Getting our hands dirty 🏋️♂️ First things first. How does this even work? Higher level... | 27,606 | 2024-06-05T10:33:36 | https://dev.to/nmitic/making-your-cv-talk-product-mindset-first-defining-features-1hp9 | uxdesign, ui, buildinpublic | ## Getting our hands dirty 🏋️♂️
First things first. How does this even work? Higher level concept is actually very simple, but it is important to be understood before jumping into the actually implementation. As understanding it better, means one will able to challenge it, come up with something better and it means actual implementation will be streamed from a place of understanding allowing us to avoid hitting road blocks where we really should not.
I like to approach designing concepts from well defined requirements. I also like to distinguish 3 main type of requirements:
I call it Semaforoments (My wife will understand 😂)
1. Business requirements (What I want) 🔴 STOP
2. Product requirements (What I need) 🟡 READY
3. Engineering requirements (What I must) 🟢 GO
One is streamed from the another. Just like in traffic light, order must be respected. It is simple flow of information.
### Business requirements
> I WANT to save time and be able to take more interviews with higher possibility of a potential match!
### Product requirements
> I NEED a frictionless user interface which will allow hiring manager and recruiters to bypass initial candidate interview.
I need interface to be as human as possible to imitate real interview, thus responses and tone of it needs to be genuine, real and absolutely authentic.
### Engineering requirements
> I MUST build a responsive web app, working across device sizes and computing power. I must stream the information and interview responses in chunks in order have frictionless experience.
I must be able to develop and release continuously. I must dedicated service for each one respectively:
> - Content data
> - Handling of interview responses
> - Web app hosting
In my humble opinion (which lately is become less and less humble 🤪), exact features to be built are a marriage between product and engineering requirements, as I believe building great software product is possible where developers and product owners are working **_WITH_** each other not **_FOR_** each other.
### Features
1. I can see online CV using the link I can share.
2. I can edit the content of CV without having to write any code.
3. I can feed CV content data to any consumer that is interested in it.
4. I can chat with CV and responses will be streamed so that waiting time is reduced.
5. I can talk to CV and it will respond me in candidate real human authentic voice.
6. I can see tweet like blog post from candidate to get more insights about their thinking.
7. I can ask question related to candidate views outside of work experience getting to know the candidate personality and way of thinking.
8. I can save PDF document of chat conversation.
9. I can save PDF document of CV.
From here we will focus on the following two:
**Chat interface**
> I can chat with CV and responses will be streamed so that waiting time is reduced.
**Audio / Talk interface**
> I can see tweet like blog post from candidate to get more insights about their thinking

1. Online CV https://nikola-mitic.dev/cv/patient21
2. Blog / Tweet like interface https://nikola-mitic.dev/tiny_thoughts
3. Chat interface to let people chat to your CV https://nikola-mitic.dev/ai_clone_interview/chat
4. And finally audio interface to give your CV voice and let people talk to your CV https://nikola-mitic.dev/ai_clone_interview/talk
Entire source code:
1. [Backend Service AI related code](https://github.com/nmitic/ai-interviewer)
2. [Client using Next JS](https://github.com/nmitic/nikola.mitic.dev)
## Preamble
It's the year 2024 and tech word is going crazy. Somehow you find yourself in a need for a new job. You start applying for jobs. And you keep applying, and you apply some more, and more, and even more.
But that right job offers does not come!
And you start asking yourself what are you doing wrong, and how can you optimise your job search, since by now your figure it out it is a numbers game! As market is saturated with us developers (especially us web frontend developers).
This is where I am at the moment, and where I was for the past 2 years.
There is much I can say about this topic, and hopefully help others, as well as get off my chest all the unfairness going around job market at the moment. But I won't.
Instead I want to share what help me optimise and reduce the amount of interviews I am having which otherwise should not even happen as they bring no job opportunities.
> Simply put I want to clear out all the processes which are not a match, while also increasing amount of processes which are more likely to be a match.
By now you already experiences automatic CV filtering, where some sort of AI will scan your CV and you would be marked as match or not. You might not like it, I know I do not, but it makes sense. I wanted to do the same with companies.
Ex coworker of mine, said.
> This is like playing uno reverse card on companies using AI to filter our job applications, we should just let their AI bots talk to our AI bots.
To make it clear, that was never a goal. But it does sounds funny. Tech interviews are known to be ridiculously long. 6 rounds seems to be the norms nowadays. So let's do some basic math (the only one I know), if you have 10 interviews a week (which has been a norm for me), and half of it is first round where they ask basic questions, and if one interview as such lasts 30 minutes, you just save yourself 7.5 hours per week! You got almost a full work day back.
Not too bad!
Solution is rather simple:
Have an AI be aware of you resume, build a simple chat interface, where hiring managers and recruiters can ask questions which they usually asked on first initial calls.
## Before we start
I won't be explaining line by line, after all how you do things is up to you. However, I will explain the concept, give you the blueprint, give you detailed solution to a common problems you will encounter and share the whole repo to the relevant code for guidance.
I believe you can learn a lot and have fun in the process.
## Prerequisites
- For the concept itself nothing, you do not even need to be a developer. If you are not a developer and fail to understand, it is up to me! I did a bad job explaining it.
- For implementation you can choose your own stack, I went with
1. NextJS with TS - For CV implementation
2. Tailwind CSS - For styling
3. Node JS - For the one and only BE service we will be writing
4. Llamaindex TS - To easy out working with LLM
5. Open AI api - For both LLM and embedding model
6. Groq API - For LLM, optimal, but at the time of writing it is free
7. Eleven labs API - For voice cloning and streaming
8. Hygraph - For content hosting
9. Vercel - For deployment CV hosting / deployment
10. Renderer for Node JS service hosting / deployment
## But wait how much will I have to pay for this? 💸
Almost nothing! Except for Open AI all of the tools have generous free tiers, limits you will hardly surpass, considering that this is your online CV it really should not be getting a tone of visitors

To understand the power of such functions you can read some of our previous articles about the subject.

* [The Sickest B2B sales AI Chatbot you have Ever Seen](https://ainiro.io/blog/the-sickest-b2b-sales-ai-chatbot)
You can also try out our AI functions by for instance asking our chatbot to <a href="#" onclick="ainiro_faq_question(event); return false;">How's the weather today?</a>
## How an AI function work
If a user asks a question we've got an AI function for, we instruct OpenAI to return a _"function invocation"_. A function invocation for our AI chatbot looks as follows.
```
___
FUNCTION_INVOCATION[/modules/openai/workflows/workflows/web-search.hl]:
{
"query": "Who is the World Champion in Chess",
"max_tokens": 4000
}
___
```
If the AI function takes arguments, and the user has not specified values for these arguments, OpenAI will ask the user for values for these argument. You can see this process in the following screenshot.
<img alt="Asking our AI chatbot about the weather" src="https://ainiro.io/assets/images/blog/asking-our-ai-chatbot-about-the-weather.png" style="max-width: 550px;margin-left: auto;margin-right: auto;">
The whole training snippet for our weather logic looks like this.
**Prompt**
How is the weather tomorrow?
**Completion**
```
Retrieves the weather for some specified location by searching DuckDuckGo
and scraping its resulting URLs. If the user asks about the weather,
then construct a search [query] likely to return the weather and respond
with the following:
___
FUNCTION_INVOCATION[/modules/openai/workflows/workflows/web-search.hl]:
{
"query": "[query]",
"max_tokens": "[max_tokens]"
}
___
It is very important that you put the FUNCTION_INVOCATION parts and the JSON
payload inside of two ___ lines. Always use 4000 for the above [max_tokens].
If the user does not provide you with a location, such as a city or a country,
then ask the user for a location before you respond with the above. Explain to
the user what you're about to do before returning the above.
```
If you look carefully at the above screenshot, you will see how I didn't provide a location first, so the chatbot asks the user for a city or a country before it actually returns the function invocation.
When OpenAI returns, we check if it returned `___` (3 underscore characters), and if it did, we check if there are any function invocations in one of its sections. If there are function invocations, and these are declared on the specific type/model, we execute these functions, and invoke OpenAI afterwards with the result of the function invocation.
This allows us to have OpenAI dynamically assemble _"code"_ that executes on your cloudlet, for then to transmit the result of executing the code bask to OpenAI again, and have it answer your original question. The last part is important to understand, since when an AI function is invoked, the backend actually invokes OpenAI _twice_. Once to generate the function invocation _"code"_, and another time to answer the original question based upon whatever the function invocation returned.
The cloudlet again will transmit the result of the function invocation as JSON to OpenAI, allowing OpenAI to semantically inspect it, and answer the original query, using the function invocation's result as its primary source for information required to answer the question.
You can actually see this process in your History tab (starting from version 19.7.2, not yet released) by seeing you've got multiple requests for a single question, resembling the following.
* [1] - Larnaca
* [2] - Larnaca
The first history request above is when the user answers _"Larnaca"_, and this invocation returns the function invocation. The second request is the result OpenAI generated based upon the JSON payload the function transmitted to OpenAI that was created by invoking the function. You can see how this should look like in your history tab in the following screenshot.
<img alt="How an AI functionm creates TWO history requests" src="https://ainiro.io/assets/images/blog/how-an-ai-function-generates-two-history-requests.png" style="max-width: 850px;margin-left: auto;margin-right: auto;">
**Notice** - The above screenshot illustrates a feature not yet released, scheduled for being released next Sunday.
Since we are keeping up to a maximum of 15 session items while invoking OpenAI, this allows the user to ask follow up questions based upon the result of a function invocation, such as for instance _"How is the UV index for tomorrow?"_
## How to declare an AI function
AI functions _have_ to be declared on your type/model. This is a security feature, since without this, anyone could prompt engineer your chatbot, and have OpenAI return malicious functions, that somehow harms your system. There are 3 basic ways to declare functions on your type, these are as follows.
1. Using the UI and clicking the _"Add function"_ on your type while having selected the training data tab in your machine learning component
2. Manually create a training snippet that contains a function declaration resembling the above training snippet
3. Adding a system message rule to your type's configuration
Number 1 and 2 above are probably easily understood, and illustrated in the above example code for an AI function training snippet. However, it should resemble the following.
<img alt="AI function training snippet for asking how the weather is" src="https://ainiro.io/assets/images/blog/weather-training-snippet-as-ai-function.png" style="max-width: 750px;margin-left: auto;margin-right: auto;">
## Adding AI Functions to your System Message
Having AI functions as training snippets is probably fine for most use cases. The above training snippet for instance will probably kick in on all related questions, such as ...
* How's the weather today?
* How is the weather going to be tomorrow?
* Check the weather in Oslo?
* Etc ...
However, for some _"core AI functions"_, it might be better to add these as a part of your system instruction instead. Examples can be for instance _"Search the web"_ or _"Scrape a website"_, etc. These are _"core"_ functions, and you might imagine the user asking questions such as.
* Search for Thomas Hansen Hyperlambda and create a 2 paragraph summary
The above might not necessarily be able to find a training snippet with a prompt of _"Search the web"_, so it might be better to add such AI functions into your system message, as a core part of your chatbot's instructions. On our AI chatbot we have done this with the following rule added to our system message.
```
**How to search the web**
If the user asks you to search the web, then inform the user of what you
are about to do, and create a search query that is relevant to the user's
request, and do not return follow up questions, but instead end your
response with the following:
___
FUNCTION_INVOCATION[/modules/openai/workflows/workflows/web-search.hl]:
{
"query": "[query]",
"max_tokens": 4000
}
___
It is very important that you put the FUNCTION_INVOCATION parts and the
JSON payload inside of two ___ lines. If the user does not tell you what
to search for, then ask the user for what he or she wants to search for
and use as [query] before responding with the above.
```
To add the above as a part of your system message, just click your machine learning type's _"Configuration"_ button, and make sure you add the above text at a fitting position into your chatbot's system message field. Below is a screenshot of how we did this for our search the web function.
<img alt="AI functions in your system message" src="https://ainiro.io/assets/images/blog/ai-functions-as-system-messages.png" style="max-width: 850px;margin-left: auto;margin-right: auto;">
## Low-Code and No-Code AI functions
In addition to manually constructing AI functions, you can also use our No-Code and Low-Code parts to automatically add AI functions to your type.
1. Click training data
2. Filter on the type you want to add a function to
3. Click _"Add function"_
This brings up a form resembling the following.
<img alt="No-Code and Low-Code AI functions" src="https://ainiro.io/assets/images/blog/no-code-ai-functions.png" style="max-width: 850px;margin-left: auto;margin-right: auto;">
These are pre-defined AI functions, and what functions you've got in your cloudlet depends upon what plugins you've installed. However, the core of Magic has a list of basic AI functions, such as the ability to sending the owner of the cloudlet an email, etc.
If you need more AI functions, check out your _"Plugins"_, and install whatever plugin happens to solve your need for AI functions. Notice, documenting AI functions in plugins could be improved. If you're looking for a specific AI function, you can [send me an email](mailto:thomas@ainiro.io), and I will show you which plugin you need, and/or create a new AI function for you that solves your problem.
## Creating your own AI functions
In addition to the above, you can also create your own AI functions using [Hyperlambda workflows](https://docs.ainiro.io/workflows/). A Hyperlambda workflow is basically the ability to dynamically create Hyperlambda code, without having to manually write code, using Low-Code and No-Code constructs. You _can_ manually write code, and add to your workflow, but coding is optional.
Creating a Hyperlambda Workflow is outside of the scope of this article, but as long as you put your Hyperlambda file inside a module folder named _"workflows"_, the above _"Add function to type/model"_ dialogue will allow the user to automatically install your AI function into a type/model. If you want to know more about Hyperlambda workflows you can check out the following tutorial.
* [Create a registration API in 15 minutes](https://ainiro.io/blog/create-a-registration-api-in-15-minutes)
Notice, when you create your Hyperlambda workflows you need to _think_. Because by default any anonymous user can execute the workflow's code on your cloudlet, so you need to make sure the user is not allowed to execute code that somehow might be maliciously constructed by prompt engineering your chatbot. The above is a really great example of how to create a workflow, but it's also a _terrible_ example of an AI function, since allowing people to register in your AI chatbot, is probably not a good idea - At least not the way it's implemented in the above tutorial.
## Prompt Engineering and AI is the Real No-Code Revolution
Most of the work related to creating AI functions is in fact prompt engineering and not coding. This allows you to leverage your prompt engineering skills to construct really complex functionality, arguably replacing your coding abilities with your prompt engineering skills.
In the future I anticipate that 90% of the work related to AI functions, and creative use cases, will not originate from software developers, but rather from prompt engineers and No-Code devs, that are able to intelligently assemble and combine pre-defined functions together, to solve complex problems, without having to code.
However, to facilitate for this revolution, we (devs) need to create basic building block functions, that No-Code devs can assemble together, without having to code. This allows No-Code devs to prompt engineer our basic building blocks together, creating fascinating results with complex functionality. Below is an example of how prompt engineering can be used inside of the chatbot itself, to create _"complex functionality"_, leveraging AI to generate some result.
<img alt="Using our AI functions to compare HubSpot to AINIRO" src="https://ainiro.io/assets/images/blog/ainiro-versus-hubspot-ai-function-invocation.png" style="max-width: 650px;margin-left: auto;margin-right: auto;">
The above is probably an example that is within reach of 90% of the world's _"citizens"_ to understand, arguably becoming the _"democratisation of software development"_, which again of course is the big mantra of the No-Code movement.
> The No-Code revolution isn't about No-Code, it's about AI and prompt engineering
## Wrapping up
I haven't had this much fun since I was 8 years old. AI functions is the by far coolest thing I've worked on for a very, very, very long time. By intelligently combining AI functions together, we can basically completely eliminate the need for a UI, having the AI chatbot completely replace the UI of at least in theory any application you've used so far in your life.
Then later as we add the Whisper API on top of our AI chatbot, you're basically left with _"an AI app"_ you can speak to, through an ear piece, completely eliminating the need for a screen.
AI functions is something we take very seriously at AINIRO, and definitely one of our key focal areas in the future - Due to the capacity these have for basically becoming a _"computer revolution"_, where your primary interface for interacting with your comnputer becomes your voice, and/or natural language.
In addition, our AI functions feature also makes _"software development"_ much more available for the masses, including those with no prior coding skills - So it becomes a golden opportunity for software developers and No-Coders to collaboratively work together, to create complex functionality, solving real world problems, while democratising software development for the masses.
To put the last statement into perspective, realise that roughly 0.3% of the world's population can create software, while probably 95% of the world's population can prompt engineer, and apply basic logic to an AI chatbot, creating beautiful software solutions in the process. Hence ...
> The No-Code Revolution **is** AI and prompt engineering, and we're in the middle of it all ... 😊

1,877,893 | Advanced Linux Shell Scripting: Unlocking Powerful Capabilities | Advanced Linux Shell Scripting: Unlocking Powerful Capabilities Shell scripting is a... | 0 | 2024-06-05T10:27:22 | https://dev.to/iaadidev/advanced-linux-shell-scripting-unlocking-powerful-capabilities-4ien | devops, linux, bash, shellscirpting | ### Advanced Linux Shell Scripting: Unlocking Powerful Capabilities
Shell scripting is a fundamental skill for any Linux user, system administrator, or DevOps engineer. While basic scripts are great for simple automation tasks, advanced shell scripting techniques allow you to create more robust, efficient, and powerful scripts. This blog will delve into advanced concepts like functions, error handling, debugging, and integrating with other tools. By the end, you'll be equipped to tackle complex automation challenges with ease.
#### 1. Functions: Organizing and Reusing Code
Functions are reusable blocks of code that make scripts more modular and easier to maintain. Here’s a quick refresher on defining and using functions in a shell script:
```bash
#!/bin/bash
# Define a function
greet() {
local name=$1
echo "Hello, $name!"
}
# Call the function
greet "Alice"
greet "Bob"
```
In this example, `greet` is a function that takes one argument (`name`) and prints a greeting message. Using `local` ensures the variable scope is limited to the function, preventing unexpected behavior in larger scripts.
#### 2. Error Handling: Making Scripts Robust
Error handling is crucial for creating reliable scripts. Using `set -e` ensures the script exits immediately if any command fails:
```bash
#!/bin/bash
set -e
mkdir /some/directory
cd /some/directory
touch file.txt
echo "All commands executed successfully!"
```
For more granular control, use `trap` to catch errors and execute a specific function:
```bash
#!/bin/bash
trap 'echo "An error occurred. Exiting..."; exit 1;' ERR
echo "Executing command..."
false # This command will fail
echo "This line will not be executed."
```
In this script, if any command fails, the `trap` command will print an error message and exit the script.
#### 3. Debugging: Finding and Fixing Issues
Debugging shell scripts can be tricky, but tools like `set -x` can help by printing each command before it is executed:
```bash
#!/bin/bash
set -x
echo "This is a test script."
false # Intentional failure to demonstrate debugging
echo "This will not be printed."
```
By running this script, you’ll see each command printed to the terminal, making it easier to identify where things go wrong.
#### 4. Working with Arrays: Managing Complex Data
Arrays allow you to store multiple values in a single variable, which is useful for handling lists and other complex data structures:
```bash
#!/bin/bash
# Declare an array
fruits=("Apple" "Banana" "Cherry")
# Access array elements
echo "First fruit: ${fruits[0]}"
# Loop through the array
for fruit in "${fruits[@]}"; do
echo "Fruit: $fruit"
done
```
This script demonstrates how to declare an array, access individual elements, and iterate through all elements.
#### 5. Advanced Text Processing: Using `awk` and `sed`
`awk` and `sed` are powerful text processing tools that can manipulate text files and streams efficiently:
```bash
#!/bin/bash
# Using awk to print specific columns
echo -e "Name\tAge\nAlice\t30\nBob\t25" | awk '{print $1}'
# Using sed to replace text
echo "Hello World" | sed 's/World/Shell/'
```
In this example, `awk` prints the first column from a tab-separated list, and `sed` replaces "World" with "Shell" in the input string.
#### 6. Script Parameters: Enhancing Flexibility
Scripts can accept parameters to increase their flexibility and usability:
```bash
#!/bin/bash
if [ $# -lt 2 ]; then
echo "Usage: $0 <name> <age>"
exit 1
fi
name=$1
age=$2
echo "Name: $name, Age: $age"
```
This script checks if at least two parameters are provided and then uses them within the script.
#### 7. Integrating with Other Tools: Combining Power
Advanced scripts often integrate with other command-line tools and utilities. Here’s an example of using `curl` to fetch data from an API and `jq` to parse JSON:
```bash
#!/bin/bash
# Fetch weather data for a given city
city="London"
api_key="your_api_key_here"
response=$(curl -s "http://api.openweathermap.org/data/2.5/weather?q=$city&appid=$api_key")
# Parse and display the temperature
temp=$(echo $response | jq '.main.temp')
echo "The temperature in $city is $temp Kelvin."
```
This script uses `curl` to retrieve weather data and `jq` to extract the temperature from the JSON response.
#### 8. Background Jobs: Running Tasks Concurrently
Running tasks in the background allows scripts to perform multiple operations simultaneously:
```bash
#!/bin/bash
# Run tasks in the background
sleep 5 &
pid1=$!
sleep 10 &
pid2=$!
# Wait for all background jobs to complete
wait $pid1
wait $pid2
echo "All background tasks completed."
```
This script runs two `sleep` commands in the background and waits for both to complete before proceeding.
#### Conclusion
Advanced shell scripting in Linux unlocks a world of possibilities for automation, system management, and efficient workflow execution. By mastering functions, error handling, debugging, arrays, text processing, script parameters, tool integration, and background jobs, you can create powerful scripts that tackle complex tasks with ease. Start experimenting with these advanced techniques and see how they can enhance your scripting capabilities!

1,877,859 | How to Read/Write from Credential Manager in .NET 8 | How to Read/Write from Credential Manager in .NET 8 Credential Manager is a secure storage... | 0 | 2024-06-05T10:15:05 | https://dev.to/issamboutissante/how-to-readwrite-from-credential-manager-in-net-8-1ag | dotnet, credentialmanager, secretkeydotnet, csharp | ## How to Read/Write from Credential Manager in .NET 8
Credential Manager is a secure storage solution for sensitive information, such as usernames and passwords. It provides a way to manage credentials for various applications securely. In this article, we will walk through the steps to read, write, update, and delete credentials in .NET 8 using the Meziantou.Framework.Win32 library, which also works in .NET 6 and 7.
### Setting Up the Project
Before we dive into the code, ensure you have the following NuGet package installed in your .NET project:
```shell
dotnet add package Meziantou.Framework.Win32
```
### Writing Credentials to Credential Manager
To securely save credentials, we can use the `CredentialManager.WriteCredential` method. Here is a step-by-step guide:
1. **Define the Credential Information:**
- `applicationName`: A unique identifier for the application.
- `userName`: The username associated with the credential.
- `secret`: The password or sensitive information.
- `comment`: A description for the credential.
- `persistence`: Determines how the credential is stored (Session, LocalMachine, Enterprise).
```csharp
using Meziantou.Framework.Win32;
using System;
public class CredentialManagerHelper
{
public static void SaveCredential(string applicationName, string userName, string secret, string comment, CredentialPersistence persistence)
{
CredentialManager.WriteCredential(
applicationName: applicationName,
userName: userName,
secret: secret,
comment: comment,
persistence: persistence);
}
}
```
2. **Usage Example:**
```csharp
class Program
{
static void Main(string[] args)
{
string appName = "MyApp";
string userName = "user123";
string password = "P@ssw0rd!";
string comment = "User login information";
CredentialManagerHelper.SaveCredential(appName, userName, password, comment, CredentialPersistence.LocalMachine);
Console.WriteLine("Credential saved successfully.");
}
}
```
### Reading Credentials from Credential Manager
To retrieve the stored credentials, use the `CredentialManager.ReadCredential` method:
```csharp
public class CredentialManagerHelper
{
public static Credential ReadCredential(string applicationName)
{
var credential = CredentialManager.ReadCredential(applicationName);
if (credential == null)
{
Console.WriteLine("No credential found.");
return null;
}
Console.WriteLine($"UserName: {credential.UserName}");
Console.WriteLine($"Secret: {credential.Password}");
Console.WriteLine($"Comment: {credential.Comment}");
return credential;
}
}
```
### Updating Credentials
Updating a credential is straightforward. Simply call the `SaveCredential` method again with the same `applicationName`:
```csharp
public static void UpdateCredential(string applicationName, string newUserName, string newSecret, string newComment)
{
SaveCredential(applicationName, newUserName, newSecret, newComment, CredentialPersistence.LocalMachine);
}
```
### Deleting Credentials
To remove a credential, use the `CredentialManager.DeleteCredential` method:
```csharp
public class CredentialManagerHelper
{
public static void DeleteCredential(string applicationName)
{
try
{
CredentialManager.DeleteCredential(applicationName);
Console.WriteLine("Credential deleted successfully.");
}
catch (Exception ex)
{
Console.WriteLine($"Error deleting credential: {ex.Message}");
}
}
}
```
### Understanding Credential Persistence
The `CredentialPersistence` enumeration defines how credentials are stored:
- **Session**: Credentials are only available for the current session.
- **LocalMachine**: Credentials are saved for the current user on the local machine and are not accessible by other users.
- **Enterprise**: Credentials are available to all authenticated users on the domain.
```csharp
public enum CredentialPersistence : uint
{
Session = 1,
LocalMachine,
Enterprise,
}
```
### Full Example
Here is a complete example that demonstrates creating, reading, updating, and deleting credentials:
```csharp
using Meziantou.Framework.Win32;
using System;
public class CredentialManagerHelper
{
public static void SaveCredential(string applicationName, string userName, string secret, string comment, CredentialPersistence persistence)
{
CredentialManager.WriteCredential(
applicationName: applicationName,
userName: userName,
secret: secret,
comment: comment,
persistence: persistence);
}
public static Credential ReadCredential(string applicationName)
{
var credential = CredentialManager.ReadCredential(applicationName);
if (credential == null)
{
Console.WriteLine("No credential found.");
return null;
}
Console.WriteLine($"UserName: {credential.UserName}");
Console.WriteLine($"Secret: {credential.Password}");
Console.WriteLine($"Comment: {credential.Comment}");
return credential;
}
public static void UpdateCredential(string applicationName, string newUserName, string newSecret, string newComment)
{
SaveCredential(applicationName, newUserName, newSecret, newComment, CredentialPersistence.LocalMachine);
}
public static void DeleteCredential(string applicationName)
{
try
{
CredentialManager.DeleteCredential(applicationName);
Console.WriteLine("Credential deleted successfully.");
}
catch (Exception ex)
{
Console.WriteLine($"Error deleting credential: {ex.Message}");
}
}
}
class Program
{
static void Main(string[] args)
{
string appName = "MyApp";
string userName = "user123";
string password = "P@ssw0rd!";
string comment = "User login information";
// Save credential
CredentialManagerHelper.SaveCredential(appName, userName, password, comment, CredentialPersistence.LocalMachine);
Console.WriteLine("Credential saved successfully.");
// Read credential
CredentialManagerHelper.ReadCredential(appName);
// Update credential
CredentialManagerHelper.UpdateCredential(appName, "newUser", "NewP@ssw0rd!", "Updated user login information");
// Read updated credential
CredentialManagerHelper.ReadCredential(appName);
// Delete credential
CredentialManagerHelper.DeleteCredential(appName);
}
}
```
### Conclusion
In this article, we've covered how to read, write, update, and delete credentials using the Credential Manager in .NET 8. This approach ensures that sensitive information is stored securely, leveraging the built-in capabilities of the Windows operating system. By following these steps, you can manage your application's credentials securely and efficiently.
