last month i enrolled for META FRONTEND DEVELEOPER PROFESSIONAL CERTIFICATE. It Comprises of 9 course series. Today marks the completion of my first Course Series out of 9. This beginner Course gave me a surface level idea of Frontend Development. Starting from HTML | CSS | React | Internet | DOM | Bootstrap . It gave a really good basic understanding of how the websites work and how to make user-friendly and responsive websites.
the total estimated time given by coursera is around 7 months if we go by 6 hr per week (which is quite slow according to me), we can easily do this complete course in 45 days (1.5 months) by working around 5-6 hr a day depending on your individual learning schedule. I look forward to make a successful career i
Error Handling in Rust: A Robust Guide with Practical Examples
Tags: rust, errors
Published: 2024-02-05 05:53:30

In Rust, effective error handling is crucial for building reliable and maintainable applications. Unlike languages with garbage collection, Rust enforces ownership and memory safety, requiring explicit handling of potential errors that could arise during program execution.

**Key Concepts:**

* **`Result`**: The primary type for representing success (with a value of type `T`) or error (with a value of type `E`).
* **`match`**: A powerful expression for handling different cases, including success and error variants of `Result`.
* **`?` (question mark) operator**: Propagates errors up the call stack, simplifying error handling flow.
* **Custom Error Types**: Define your own error types to provide more meaningful context and error handling options.

**Example: File Processing:**

```rust
use std::fs::File;
use std::io::Read;

fn read_file(filename: &str) -> Result<String, std::io::Error> {
    let mut file = File::open(filename)?;
    let mut contents = String::new();
    file.read_to_string(&mut contents)?;
    Ok(contents)
}

fn main() {
    let result = read_file("existing_file.txt");
    match result {
        Ok(contents) => println!("File contents: {}", contents),
        Err(err) => println!("Error reading file: {}", err),
    }
}
```

- `read_file` returns a `Result<String, std::io::Error>` to indicate either success with a string or failure with an `io::Error`.
- `?` propagates errors up the call stack, returning early from `main` if `read_file` fails.
- `match` handles both success and error cases appropriately.

**Advanced Practices:**

* **Chaining Operations:** Use `?` to chain operations and propagate errors efficiently.
* **Custom Errors:** Define specific error types for better error handling granularity.
* **Error Recovery:** Implement logic to recover from certain errors if possible.
* **Error Propagation Control:** Decide when to handle errors locally or propagate them further.
* **Testing:** Rigorously test error handling scenarios to ensure robustness.

**Benefits of Effective Error Handling:**

* **Increased Reliability:** Prevents unexpected crashes and ensures program stability.
* **Improved Maintainability:** Makes code easier to understand and debug.
* **Enhanced User Experience:** Provides informative error messages to users.
* **Stronger Security:** Detects and handles potential security vulnerabilities.

Remember, error handling is not just about preventing crashes; it's about designing programs that can gracefully handle any situation, offering informative feedback to users and making your code more resilient and user-friendly.
Record and Pattern Matching in C# 9
Tags: csharp
Published: 2024-02-05 07:15:09

C# 9, the latest version of the widely-used programming language, introduces powerful new features that can greatly simplify your code and make it more expressive. Two of the most exciting additions are C# Record and Pattern Matching.

C# Record is a new reference type that provides a concise and immutable way of declaring classes. It combines the benefits of classes and structs, offering built-in equality, immutability, and value-based equality semantics. With Records, you no longer need to write boilerplate code for equality checks. The compiler generates it for you, making your code cleaner and more maintainable.

To define a record in C# 9, you simply use the `record` keyword followed by the name of the record and its properties. Here's an example that defines a `Person` record with `Name` and `Age` properties:

```csharp
public record Person(string Name, int Age);
```

With this small amount of code, you automatically get features such as value-based equality, value-based comparison, pattern matching, and deconstructing. The generated equality and comparison methods compare all properties by default, making it easy to check if two instances of a record are equal.

Pattern Matching is another powerful feature introduced in C# 9 that allows you to perform complex pattern-based operations on your data. It simplifies conditional checks and enables you to extract data from objects in a more concise and readable way.

An example of pattern matching is using the `is` keyword to check if an object matches a particular pattern. Let's say you have a list of people, and you want to find all the adults:

```csharp
List<Person> people = GetPeople();

foreach (var person in people)
{
    if (person is Person { Age: >= 18 })
    {
        Console.WriteLine($"{person.Name} is an adult");
    }
}
```

In this code snippet, we iterate over the list of `People` and use pattern matching to check if each person is an adult (age greater than or equal to 18). We can access the `Age` property directly within the pattern, simplifying the code and making it more readable.

Pattern matching also works well with records. You can easily check if two records have the same values for certain properties:

```csharp
Person person1 = new Person("John", 25);
Person person2 = new Person("John", 25);

if (person1 is person2)
{
    Console.WriteLine("person1 and person2 have the same values");
}
```

In this example, the `is` pattern matches `person2` against `person1`, allowing us to determine if both records have the same values for all properties.

C# 9's Record and Pattern Matching features provide a powerful combination for simplifying and enhancing your code. They offer concise syntax, improved readability, and reduced boilerplate code. By using these features, you can write cleaner and more maintainable code, saving time and effort in the long run. So, dive into C# 9 and start taking advantage of these exciting new features in your projects!
Oxylabs Go SDK
Tags: oxylabs, go, news, api
Published: 2024-02-05 09:22:16

Hey everyone! We've created an Oxylabs Go SDK that'll allow users to more easily utilize the Oxylabs SERP APIs (and more later) via a Golang library.

You can find it here: https://github.com/mslmio/oxylabs-sdk-go

This is just an MVP and we'll be working on improving it over time with more features.

Would appreciate if Oxylabs users could try it out and give their feedback so we can start addressing it and improving the SDK.

Here's a quick start example:

```go
package main

import (
	"fmt"

	"github.com/mslmio/oxylabs-sdk-go/serp"
)

func main() {
	// Set your Oxylabs API Credentials.
	const username = "username"
	const password = "password"

	// Initialize the SERP realtime client with your credentials.
	c := serp.Init(username, password)

	// Use `google_search` as a source to scrape Google with adidas as a query.
	res, err := c.ScrapeGoogleSearch(
		"adidas",
	)
	if err != nil {
		panic(err)
	}

	fmt.Printf("Results: %+v\n", res)
}
```

It works with both the real-time and async integration methods and makes it especially easy to use the latter method which is otherwise quite tedious.

Please see detailed documentation at https://pkg.go.dev/github.com/mslmio/oxylabs-sdk-go

## O que é Grid de 8 pontos

O grid de 8 pontos é uma técnica que tem sido amplamente utilizada no mundo do design e da programação nos últimos anos. O grid de 8 pontos é quando usamos múltiplos de 8 para definir tanto o espaçamento, quanto o tamanho dos elementos da página em que estamos construindo.

A utilização de números como 8 para dimensionar e espaçar elementos torna o dimensionamento para uma ampla variedade de dispositivos. Além disso, a maioria dos tamanhos de tela populares é divisível por 8, o que facilita o ajuste. O princípio do grid de 8 pontos é usar múltiplos de 8 para layout, dimensões, preenchimento e margem dos elementos.

## Grid de 8 pontos na prática

Utilizar o grid de 8 pontos em espaçamentos nos projetos é tão simples quanto parece. Simplesmente vai fazer com que a distância de um elemento para o outro seja múltipla de 8.

Geralmente usamos uma certa distância para espaçamento entre elementos que fazem parte do mesmo conteúdo e o dobro desse espaçamento para separar novos conteúdos. Veja no exemplo abaixo:

2024-02-02: Rearing for Launch
Tags: devjournal
Published: 2024-02-06 05:25:34

This week was dedicated to preparing for our launch.

Our CEO and CSO had gone and created a UAT doc full of bugs that should be fixed before we launch, so the offshore team was busy all week fixing the stuff that I'm not specialized in, i.e. the non-LLM stuff.

Otherwise, I did a bunch of research on RAG and persistent memory for the application. As it stands, the bot doesn't remember anything between page reloads, which is definitely not ideal. I'm going to have to work on making that a reality eventually.

I also looked into our ElevenLabs implementation, since it was taking an abnormally long time to generate messages. Even though it was already on a stream, which is what I thought was the culprit, it was being sent back to the frontend as a packet instead of as part of the websocket. So I deferred that to the offshore team again.

That same day I also did some research into prompt injection prevention, and found out there are several libraries for this, so I'm going to do that as well eventually down the line. We really do not want people gaming the system.

The next day, I worked on fixing an issue with the bot not sending a proper message after onboarding was finished. Before, the bot did not understand that it was being thrusted into its "main prompt" after coming out of the onboarding process, so it would think there was some weird hiccup. I managed to fix that by having an entirely different prompt in the system for that based off the original. I also partially parameterized that prompt so there isn't too much repetition. It will lay down the pipes for future refactoring.

The next day, Thursday, I took some time in a meeting to explain the inner intricacies of the LLM app, or at least my understanding of it since a lot of it was spaghetti. I would really like to get time to refactor the whole thing but we are in a time crunch.

After that, I set out to fix up some latter issues with regard to the LLM functionality. The first one was that the "reason" field for the todo list creation kept sticking itself into the todo list for some reason. I didn't get to finish by end of day on Friday, so I'm looking to finish that as soon as possible this week.

Anyway, that's all. Till next week, cheers.
