A fatal error occurred: Unable to verify flash chip connection (No serial data received.)
Published: 2024-01-10 11:49:50

Recently, I acquired an ESP32-S3 UNO, and upon receiving it, I proceeded to test its functionality. Although it powered on normally, I encountered an issue while attempting to upload my code, receiving the error message: "A fatal error occurred: Unable to verify flash chip connection (No serial data received.)"


Assuming a potential fault with one of the boards, I tested a second, identical board, only to encounter the same error. 


This led me to conclude that the issue might lie elsewhere.

I experimented with various Type-C cables, connected to different ports, and ensured that the correct board was selected in the Arduino IDE. Despite these efforts, the issue persisted.

Numerous solutions found online proved unhelpful. However, during my research, I came across a discussion on the Arduino Forum related to a similar issue Arduino Forum Link. While the forum provided valuable insights, none of the suggested solutions seemed to work. Nonetheless, it's worth exploring these resources as your situation might differ.

Importantly, I want to note that there was no issue with my codes. I had a simple blinking LED program as follows:

``` c++

int ledPin = 12;


void setup() {
pinMode(ledPin, OUTPUT);

}

void loop() {

digitalWrite(ledPin, HIGH);
delay(200);
digitalWrite(ledPin, LOW);
delay(200);

}
```


In my continued troubleshooting efforts, I discovered a resolution that worked:

I changed the upload speed in the Arduino IDE tools settings from **921600** to **115200** and it worked.

Introducing Nightly and Beta Rust Crates
Tags: opensource, database, rust, data
Published: 2024-01-10 11:43:56

We are pleased to announce two additional Rust crates, `surrealdb-nightly` and `surrealdb-beta`. These crates are designed to complement the `surrealdb` crate. Starting with `v1.1.0` we plan to publish a stable release on the second Tuesday of every month. These stable releases are only published to the stable `surrealdb` crate. 

If you use SurrealDB in production, this is the ideal crate for you. You can add it to your project using `cargo add` or by simply adding a line like this one to your dependencies section:
​
```toml
surrealdb = "1"
```
​
## Nightly Crate
​
If you prefer living on the bleeding edge, this crate is perfect for you. It follows our development branch very closely. It’s automatically published every night but only when there are new changes to the development branch. It makes it easy to test new features as an embedded library or as a client when running a nightly binary on the server.
​
When using nightly or beta crates, we recommend adding a line similar to this one to your dependencies section in Cargo.toml:
​
```toml
surrealdb = { version = "1", package = "surrealdb-nightly" }
```
​
This makes it easy to switch between the three crates by simply changing the package name. You could start your development using `surrealdb-nightly` if the nightly version has a feature you want that hasn’t stabilised yet, later switch to `surrealdb-beta` once it reaches beta and finally switch to `surrealdb` once it’s stable. All this by simply changing the package name. This way you won’t have to update your feature flag names if you have features that activate SurrealDB features. For example `memory = ["surrealdb/kv-mem"]`.
​
## Beta Crate
​
Every month we will freeze features on the development branch by creating a new branch which will only receive bug fixes from that point onwards. This gives us a month to polish our releases before they hit the stable crate. Updates in that branch are pushed to the `surrealdb-beta` crate. New features in this crate are not guaranteed to reach the stable crate. Such features may be reverted to give them more time to develop if we think they are not ready to stabilise yet.
​
## Conclusion
​
The nightly and beta crates are great for testing new features and bug fixes. However, these are, by definition, pre-releases. Use them responsibly 😄.
Understand The Concept Of Alpha-Beta Pruning
Tags: webdev, gamedev, java, beginners
Published: 2024-01-10 11:37:33

**[Alpha-Beta Pruning](https://www.javatpoint.com/ai-alpha-beta-pruning)** is an optimization technique used in game-playing algorithms, especially in minimax search algorithms, to reduce the number of nodes evaluated in the search tree. It is commonly employed in games like chess, checkers, and tic-tac-toe.

The basic idea behind **Alpha-Beta Pruning** is to eliminate the evaluation of nodes in the search tree that are guaranteed to be irrelevant for the final decision. The algorithm maintains two values, alpha and beta, representing the minimum score the maximizing player is assured of and the maximum score the minimizing player is assured of, respectively.

During the search, if the algorithm finds a move that leads to a position worse than what the opposing player already has (beta cut-off for the maximizing player or alpha cut-off for the minimizing player), it stops evaluating further moves under that node, as they won't affect the final decision. This pruning helps reduce the time complexity of the search.

In summary, **Alpha-Beta Pruning** is a clever optimization that allows the minimax algorithm to search more efficiently by avoiding the evaluation of unnecessary branches in the game tree, making it feasible to explore deeper levels and improve the algorithm's performance in game-playing scenarios.

Conditional logging
Published: 2024-01-10 10:58:58

As your codebase grows and your system increases in complexity you need to add logs to be able to understand how your program state varies across execution.

When debugging your system you can use a debugger or add some on-off console.log to understand what is happening in your program execution.
The problem with this approach is that you need to instrument your code to be effective in solving or understanding what is going on.

## Conditional Logging

Another way to solve this is to have the logs in place, but only enable them conditionally.
If you enable all the logs are the time, you only get a lot of noise that won't help you.
If you are using JavaScript, you can use the package [debug](https://github.com/debug-js/debug) to add logs that are active by the DEBUG environment variable.


![debug](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/z16vehjdok5iuy08dhgm.png)

## What to log conditionally?

HTTP requests can be conditionally logged, so you understand what requests your program is doing and which parameters and responses.
Conditionally logging Event-Driven events can be useful for understanding what events are being emitted in which part of the code.

## In short
Instrumenting your codebase gets more important as the size and complexity of your product grows.
Use conditional logging to enable only useful logs for your needs.

TIP: how to boost your app's performance with (Angular) computed signals
Published: 2024-01-10 10:53:34

> This is an Angular Tip but works with other frameworks/libs that use signals

# 🎓 INTRO
Every time a signal changes, all dependent computations are re-triggered.
This can be a performance bottleneck.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/z565t3qgz0f5asf0v5gl.png)

Consider a counter signal and a computed signal that returns a boolean to indicate if the counter isZero or not.

```ts
isZero = computed(() => this.counter() === 0);
```

This computed signal is used to change a color based on its value.
The color turns red when the counter is zero, and green otherwise.

Usage:
```html
<span [style.color]="isZero() ? 'red' : 'green'">
```

The `isZero()` function is called every time counter changes.




---
# ❌ ALTERNATIVE VERSION

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2foqzumcqzzj7mhqklrg.png)

You may also simplify the template creating a new computed Signal to set the color:

```ts
isZeroColor = computed(
 () => this.counter() === 0 ? 'red' : 'green'
);
```

Usage:
```html
<span [style.color]="isZeroColor()">
```

This setup works, but there's a catch!

The `isZeroColor()` function is called every time counter changes, even when not necessary.
I.e. from 2 to 3, from 3 to 4, since the value is always false.

---
# 🚀 What if we could minimize the computations?
💡 How? Creating a computed signal from another computed signal.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/03bjfch6ee3cux351cez.png)



```ts
isZeroColor = computed(() => this.isZero() ? 'red' : 'green');
```

🔑 Key Benefit: `isZeroColor` is recalculated only when isZero changes.
This means if counter changes from 1 to 2, isZeroColor doesn’t recompute since isZero remains false. It only recomputes when counter goes from 1 to 0, changing isZero from false to true.

🌟 Result: We've just optimized our application! This approach reduces unnecessary computations, leading to better performance.

🤔 Why This Matters: In complex applications, such optimizations can significantly reduce the workload on the browser, leading to smoother and faster UIs.

# What is Copilot?

GitHub Copilot is an AI-powered code suggestion tool that helps developers write code faster. To use it, you should need an eligible subscription on GitHub, such as GitHub Pro, Team or Enterprise. Once you're subscribed, you can enable it in supported code editors like VS Code. You can install the Copilot extension in your supported code editor and sign in with your GitHub account.

# Is it for you?

GitHub Copilot can help beginners who are learning to code by showing examples and giving suggestions. But if you're newbie to coding and don't know any coding language, Copilot might be too advanced.

If you're just starting to learn, it's a good idea to begin with beginner-friendly coding classes or tutorials. While there are many websites to learn coding from, I suggest starting with w3schools.com.

Once you gain the basics of coding, Copilot can make learning easier and improve your coding skills.

So, Copilot best for people, who already know a little bit about coding. If you're a beginner, it's smart to start learn programming before trying out Copilot.
Terraform Fundamentals

Published: 2024-01-10 10:03:01

**Terraform Workflow:**

**Init**: This step initializes a working directory containing the Terraform configuration files. This is the first step you should run after writing a new Terraform configuration.

**Validate**: This step validates the Terraform configuration files in the working directory to ensure they are syntactically valid and internally consistent.

**Plan**: This step creates an execution plan that shows what Terraform will do to your infrastructure if you apply the configuration.

**Apply**: This step applies the changes required to reach the desired state of the configuration. By default, the application scans the current directory for the configuration and applies the changes appropriately. It will ask for confirmation before destroying it.

**Destroy**: This step destroys the Terraform-managed infrastructure. I hope this helps! Let me know if you have any other questions about Terraform.
