Embarking on a Full-Stack Adventure
Published: 2023-12-22 15:11:40

Stepping into the realm of full-stack development is like setting off on an epic quest. It's a journey that will challenge your skills, creativity, and problem-solving abilities, taking you through the frontiers of both front-end and back-end development. As a solo adventurer, you are the architect, the builder, and the visionary, crafting each component of your application from the ground up. Whether it's a personal passion project or a solution to a problem you've encountered, your first solo full-stack project is more than just coding; it's a manifestation of your ideas and abilities, a tangible expression of your determination to create something entirely yours.

**Navigating the Stack: A Symphony of Technologies**

Full-stack development is like conducting a symphony of technologies, each playing a crucial role in the final performance. On the front end, you'll weave together HTML, CSS, and JavaScript, creating the user interface and experience that will draw people into your application. Here, your design skills come to life, shaping how users interact with your creation. Transitioning to the back end, you'll architect databases, manage servers, and ensure that your application can handle the tasks it's designed for. Languages like Python, Ruby, or JavaScript (via Node.js), and frameworks like Express or Django, will become your tools for building robust, scalable systems. And let's not forget about the crucial middleware, connecting front and back with seamless, efficient communication.

**The Triumph of Creation and the Path Ahead**

Completing your first solo full-stack project is an achievement of both technical skill and personal growth. It's a testament to your ability to learn, adapt, and overcome challenges. Throughout this journey, you'll encounter bugs, face architectural decisions, and make countless choices about the best tools and practices for your project. But with each challenge comes an opportunity to learn and improve. As you deploy your application, you're not just launching a set of code into the ether; you're releasing a piece of yourself, a story of your journey in learning and creation. And as you reflect on this journey, remember that this is just the beginning. The skills, insights, and experiences gained from your first solo full-stack project lay the foundation for all the future projects to come, each one an opportunity to explore new technologies, solve new problems, and continue shaping your path as a full-stack engineer.

Tips for styling React apps in JavaScript
Tags: webdev, javascript, react, programming
Published: 2023-12-22 15:02:40


![ react and Javascript ](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/scpgqttozk0gxvptb346.png)

While many developers still use CSS to style their React apps, writing styles in JavaScript has become an increasingly popular practice as it gives all of the conveniences of CSS preprocessors without the need to learn a new language.

Most CSS-in-JS libraries involve creating a JavaScript object of styles. As an example, this is what a style object looks like using my preferred library, Aphrodite.

```
const styles = StyleSheet.create({
  container: {
    position: 'relative',
    width: 40,
    height: 50,
  },
)}
```

## Variables

Many best practices from SASS/LESS workflows still apply when using JavaScript styles. Colors fonts, and other constants can be stored as variables, which can be used like so:

```
// colors
const YELLOW = '#FFF83C';
// fonts
const BOLD = 700;
const TIMES_NEW_ROMAN = '"Times New Roman", Georgia, Serif';
// shared constants
const border = `1px solid ${YELLOW}`;
const styles = StyleSheet.create({
  textBox: {
    color: YELLOW,
    fontFamily: TIMES_NEW_ROMAN,
    fontWeight: BOLD,
    border, 
  },
)}
```
New ES6 language features come are handy for sharing styles cleanly. In the above example, border is referenced with the object literal shorthand notation.

## Use JS objects in place of mixins

The spread operator (…) is particularly useful when defining a commonly-used sequence of styles (in this example the rules needed to add an ellipsis to overflowing text).

```
const textEllipsis = {
  whiteSpace: 'nowrap',
  textOverflow: 'ellipsis',
  overflow: 'hidden',
  width: '100%',
};
const styles = StyleSheet.create({
  textBox: {
    ...textEllipsis,
    backgroundColor: 'gray',
  },
)}
```

## Create helper functions for more complex motifs

More complicated sequences of rules can be abstracted behind helper functions. For example, when styling placeholder text, I use a function that returns an object of styles:

```
const getPlaceholderStyles = obj => ({
  '::-webkit-input-placeholder': obj,
  '::-moz-placeholder': obj,
  ':-ms-input-placeholder': obj,
  ':-moz-placeholder': obj,
  ':placeholder': obj,
});
const styles = StyleSheet.create({
  input: getPlaceholderStyles({ color: RED }),
)}
```

## Be consistent about naming schemes

One of biggest advantages of writing styles in JavaScript is that classNames are scoped to each component by default. This means that conventions like BEM are unnecessary. Still, it is helpful to be consistent with a naming scheme for classNames. For example, I use container for the outermost className of each React component.

Beginner's TypeScript #5
Tags: programming, typescript, tutorial, beginners
Published: 2023-12-22 15:00:00

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6j07onust7ffxiycfuyi.png)

⭐ **Assigning Types to Variables** ⭐

We have an interface that represents a user within our system:

```ts
interface User {
  id: number;
  firstName: string;
  lastName: string;
  isAdmin: boolean;
}

```

A function called **getUserId** takes in a **user**, and returns its **id**.

```ts
const defaultUser = {}

const getUserId = (user: User) => {
  return user.id;
}

getUserId(defaultUser)
```

We have an error because it calls **getUserId** and passes in a **defaultUser** that does not match the **User** contract.

We will check the [TypeScript docs](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html) and determine how to change defaultUser.

👉 **Solution:**

By adding **: User** to **defaultUser**, we tell TypeScript that we want it to conform to our **User** interface.

```ts
const defaultUser: User = {}
```

Now TypeScript will display errors at the line where **defaultUser** is declared.

We also benefit from autocompletion for the properties!

The same **: Type** syntax can be used with other types, including **numbers** and **functions**:

```ts
let a: number = 1
```

👉 **Summary:**

As we write TypeScript, we need to think about where we want our contracts to be, and what needs to be done to meet them.

description: Our mission to manage flaky unit tests
tags: 
---
If you have a company of 200 engineers and they each waste 1 hr per week waiting to retry flaky tests, you are probably losing $500,000 per year. I can't even tell you how often it is that deploys fail due to flaky tests at most companies where I have worked.

I've set out on a mission to reduce flaky tests by 80-90%. I'm working on a general purpose flaky test management tool that anybody can use no matter how you run your tests, what programming language you use, or what test framework you are using. If you have flaky tests in your codebase, this post is for you.

When a test goes bad at your company, you usually find yourself in a position where dozens of engineers are all trying to fix the same problem at the same time, but in isolation. Each person think that they somehow broke a test and only later after someone in Slack realizes that they are all fixing the same thing does the team realize how much of a loss you're taking.

I've been working on something I call [Flaptastic](https://www.flaptastic.com/) now for 5 months or so. I invite you to give it a look at to ping me if you'd like to try it.

Flaptastic can instantly detect when a unit test has flaked so that you avoid wasting any time trying to fix code you didn't break. It uses pattern matching to figure out if the test failed because it had merit, or if it the root cause was flaky test problems.

The "killer" feature is a checkbox that will instantly disable any unit test across all feature branches and pull requests. In other words, you don't need to wait for everybody to rebase before a test gets marks as skipped. Flaptastic's unique approach allows for the unit test to be disabled instantly for everybody.

I can't find anything quite like it. I heard of an internal tool used at Google which is vaguely similar but is not setup to integrate with existing projects. So far the people who have tried this love it. We aren't charging for it at this time because we want to focus on making this as useful as possible and get the features right.

If you have flaky unit tests in a big company, please ping me and I'll work with you to help come up with a strategy to increase your test health even if you don't end up using this tool.

In the event you want to use Flaptastic, your only requirement is that your code is stored on GitHub and bonus points if your team uses Slack.

Tips for better AWS re:Invent experience
Tags: aws, reinvent, cloud
Published: 2023-12-22 14:29:46

Hello Everyone! 

This blog post is based on my experience at last year's AWS re:Invent. A few tips to make your experience better.

- Try to book your sessions as soon as the session registration opens. I did this ~2 hours later and there were no available seats for a few interesting sessions. However there could some available seats (I think that there are some reserved and there may be someone who has booked a seat but didn't show) , so if you go earlier in front of the session room you can manage to get a seat.

- Book the hotel in which you have the majority of the sessions.

- Arrive a few days earlier. The event started on Monday but I arrived in Vegas on Friday. This helped me to adjust to the time zone difference which was 10 hours. I also went to the Grand Canyon and booked 1 day trip to Los Angeles.

- Get the AWS Events app on your phone. Useful to track and manage your sessions and there is also a map.

- Use the organised by AWS shuttle bus to travel between the hotels. If you decide to walk you will lose valuable time and get tired.

- Do not underestimate the distance between the hotels.

- You should have at least 30 minutes between the sessions if there are in different hotels. After a session you need to have the time to go to the bus, a few minutes to get to the other hotel and then walk to your session.

- Meet new people and talk to them. Talk with the other attendees, presenters after the sessions and company representatives in the Expo. 

- Go to at least 1 keynote and be there early. It was very nice seeing Adam Selipsky speaking. 

- There are some free events with food and drinks organised by the companies attending the conference. You can check them and reserve a spot [here](https://conferenceparties.com/). Make sure that you do this earlier.

- Go to the Expo and get some swag for your colleagues and friends. T-shirts, stickers and many more.

- Go to the AWS party on the last day of the conference. You don't want to miss it.

- And the most important is to have fun! :)
🚀 AI Predictions: What to Expect in 2024, According to Stanford Experts?
Tags: ai, news, productivity, discuss
Published: 2023-12-22 14:25:33

Next year, 2024, will be exciting for Artificial general intelligence (AGI) or just put it simple – **AI**! Experts from Stanford University share some interesting things we can expect.

### AI Trends for 2024

- Be prepared for a wave of disinformation and deepfakes. The spread of fake videos and false information will become a major issue;
- We'll see the first AI agents that can actually do things for us, not just provide help as assistants. AI will become more integrated into our daily tasks;
- There might be a shortage of GPUs, which are essential parts needed for running LLMs, leading to new inventions in computer tech and hardware;
- Both the EU and the USA might implement new regulations for a safer and more ethical use of AI. Watch for in-depth discussions on AI's ethical implications and its impact on our daily lives;
- Regulatory efforts in AI may hit a deadlock due to the challenge of "super alignment" – aligning superintelligent AI's outcomes with human goals.

---

### While the other points are straightforward, let's see a bit deeper into the last prediction – alignment of AI systems

- The current methods of alignment (ensuring AI goals match human intentions) may fail with the emergence of superintelligent AI;
- The advent of superintelligent AI, surpassing human intellect in most economically valuable tasks, is drawing closer;
- Without new methods of "super alignment," significant challenges could arise once these AI entities emerge;
- To address this, OpenAI and Eric Schmidt have jointly announced a $10 million grant program. Admirable, though it may seem like a PR move.

For more information on these AI predictions, as always, follow me and stay tuned for updates.

Git bash for Windows users PS1 variable (aka prompt) customization
Tags: gitbash, msys, terminal, shell
Published: 2023-12-22 14:09:17

This assumes that you are located in `%USERPROFILE%` (File Explorer), otherwise, init Git bash for Windows shell session at `cd ~`: once you are there, touch `.bash_profile` via Git the bash session. Following these third-party guidelines (see [link](https://devtut.github.io/bash/customizing-ps1.html#colorize-and-customize-terminal-prompt)) we can customize our PS1 as we want to:

```bash
MY_ALIAS="vanillacamp"
export PS1='\e[0;32m$MY_ALIAS@\[\033[35m\]$MSYSTEM \[\033[33m\]\w\[\033[36m\]`__git_ps1`\[\033[0m\]\n$ '
```

> Let's clarify the snippet above:
> 
> * `MY_ALIAS` is a bash variable, that later on will be referred to using a dollar sign as the following: `$MY_ALIAS`
>     
> * the `export` keyword makes sure the PS1 will be valid among sessions (system-wise)
>     
> * PS1 variables follow ANSI-escaping standards for colouring and formatting including some special escape sequences such as `\u` for system (admin) username, or relevant
>     
> * the `$MSYSTEM` is part of MSYS2 toolchain; depending on platform `$MSYSTEM` most likely be one of the following values: [MINGW32|MINGW64|MSYS](https://www.msys2.org/docs/environments/)
>     
> * `__git_ps1` is part of Git version control that, essentially, provides the current branch as part of your prompt, thus PS1 variable you currently trying to modify
>     

Happy modifying, cheers!
