Hello everyone 👋 I am full stack javascript developer, I've been working as software engineer for more then 5 years. I started as self-taught student and I worked for 7 companies, if you are in the beginning, just know nothing is impossible

Learn Database Technical interview question: What's wrong with this table? How would you improve it? Let's imagine that a teacher: speaks several languages and teaches several subjects.

@codewithmercy Sorry, but MacBook

ThinkPad or Dell? 👀 Which one are you choosing?

@csaba_kissi @Prathkum Yes, even before the AI era

@Prathkum Writing code is like 5% or even less

AI made many people realize that engineering is far more than just writing code.

If you, as a developer, already understand what p95 latency means, congratulations, you work with high load p95 latency = the time within which 95% of requests fall. This is a better metric than the average over a given period, because a few very fast or very slow requests can significantly skew the "average"

@eddiejaoude I would like to do pair programming, human communication is underrated for developing

Do you still do pair programming? Or has AI replaced this?

Learn Database In PostgreSQL, the text and varchar data types use almost the same amount of memory for the same value. For example: “hello” = 5 bytes of data for both text and varchar(255) — the same If the string is 200 bytes: text ≈ 204 bytes varchar(255) ≈ 204 bytes There is no difference in terms of memory efficiency. The difference is in: text — no limit varchar(n) — with maximum length check In Postgres, there is no performance difference between text and varchar. There is no point in choosing varchar(n) for the sake of memory optimization.

@eddiejaoude Good question, I think, when we ask, we understand that coding should be driven by developers, who actually know what antipatterns are, and actually, software design patterns. And validation is required always when we generate something using AI

@DevMoroh yeah I did, I burnt some tokens to do it but why does it come up with the better solution from the beginning?

AI generated nested ternaries 🤮. I had to refactor to switch statements 🤓. Which do you prefer? 👇

The JavaScript community is demanding static types There is an officially open ECMAScript proposal: Type Annotations. The idea is not to "turn JavaScript into TypeScript" but to implement erased type syntax within the language itself. Erased type syntax refers to types in the code that exist for static analysis and are completely erased before execution. There is no need to compile anything, type annotations are added directly to the JS code. Type checking should be performed by external type checker, not the JS runtime itself

@vishaltweetup Who said that AI writes 90% of the code? Where did you get this number? I think it is not true. The more code you generate, the more you need to review and test

If AI writes 90% of the code, what do we call developers now?

@Aditya_181105 We can't say the strongest, because stack is tool designed to solve a specific problem. Node.js is a good solution for apps with many concurrent connections, whereas Go is for CPU-intensive backend workloads and so on

Which backend stack has the strongest future? >Java + Spring >Node.js >Go >.NET

Too soon for the first BBQ of the year? 🌞🍔🍻

@Adidotdev Did you steal my site? How dare you 😅

Here is list of My projects have a look: Https://localhost:3000/ Https://localhost:3001/ Https://localhost:3002/ Https://localhost:3003/ which one is best?

JavaScript Learn JS got a small but very practical addition: Promise.try() This is exactly the kind of feature that looks minor until you hit a function that can: - throw synchronously - or fail asynchronously One entry point, one promise chain, one .catch() for both sync throw and async reject. This is not some revolutionary new API. It is just a cleaner way to normalize uncertain code paths.

Why does the term "vibecoding" cause so much hate and annoyance among programmers? Reddit has even shut down discussions and hype surrounding AI on its developer-focused subreddits. Probably because when vibe coders are asked to show what they’ve done, it often looks good on the surface, but under the hood there’s chaos — a result of blind code generation.

@codewithmercy IntelliJ IDEA: I have been using this IDE for a long time. I like that it's free for non-commercial usage, and we don't need to install a ton of extensions like for VSCode

What's your first editor?

@denicmarko I think any social platform is good. It depends on you, as a creator and as an author. I believe you can produce useful content for dev community everywhere

What's the best social network for developers?

@Mr_Salio I disagree because designers are not just drawing UI graphics. It requires a very deep understanding of context and business communication. In terms of implementing the end prototype, it could really help, but don't replace designers of course

@DevMoroh Gpt latest model Cooked designers 💀

Is there any AI better than Chat gpt for coding right now?

My work as a developer has long gone beyond simply closing issues in Jira. I could set my sights on career advancement, but I enjoy sharing my experience and working on projects that help other developers
