Diving deep into topics is worth it even more in the AI era
When you talk with people, they can feel it
You know your sh*t
And they know you know it
- Easy to find opportunities on the market
- Easier to negotiate offers
- Easier to become irreplaceable

Is it even legal to have live coding with basically a whiteboard these days?
I thought it was all gone, but turns out it's not
People who are still doing it are losing talent

Been digging through all the tooling that we have to run Node.js with TypeScript
Turns out, this field is not as simple as it might look like, especially with all the recent advancements in Node.js itself with native TypeScript support 🧵

I like how nicely Claude Code integrated with Webstorm. When you use the normal mode, Claude will first ask you if changes should be applied
Instead of having to deal with those diffs in the terminal, we can do that directly in the IDE with all the powerful tooling it has

I've seen people dunking on the latest updates with the Claude Code syntax highlight, but I don't get it
The product is not only about the raw power and speed. UX/DX is important

Really love how VS Code can restart extensions separately from restarting the editor
Something that I wish WebStorm and other JetBrains IDEs had
Why do I have to restart the whole IDE just to get the updated version of a single plugin? Cmon

Wow, the Terminal view mode in WebStorm/IntelliJ is a banger
I was always feeling like there was just not enough space, and I wanted to have a terminal and editor in separate windows/workspaces
Just found out that you can easily do that with Window view mode 🔥

Just came back from a Singapore trip
The city is amazing. Clean, well-organized, safe
I haven't seen a single homeless or a stray dog/cat during my stay there
The best subway that I've been to so far
Highly recommend

I was curious about why I don't hear about UDP servers in Node.js much
Turns out there are reasons for that, especially when we're talking about the high-throughput servers that have to handle a decent load
There are many reasons for that, but I identified 2 big ones: 🧵

I'm pretty happy with how WebStorm is doing right now with its AI assistant
The best refactoring toolset on the market, combined with good autocompletion from AI
Hard to imagine a better combo, especially if they get their AI offering close to the market leaders' level

Got a standing desk about a week ago
The huge benefit that I've noticed so far is the state of alertness
When you work from the comfort of your chair, it's easy to feel lazy at times, but I haven't felt anything like that while standing

You purchase the JetBrains AI assistant for a year

Just moved to a new place with enough space for a home office
It is a game-changer. Have never worked this comfortably from home in a looong time
In terms of comfort, it's better than any coworking. Though the coworking vibe is unmatched when you have like-minded people around

I rarely see advanced Node.js courses
Most of them are about the same things: a weather app, streams, buffers, connect to the database, and do basic operations
Don't get me wrong, those are all valuable skills, but they are not enough for building production-ready apps...

Still, there is no editor/IDE that comes close to JetBrains products in terms of refactoring things.
AI can make up for that part, at least not on the same level of convenience.
Even this feature alone is enough for me to justify the costs and keep using their IDEs.

Feels like sticking with JetBrains as one of the main IDEs was the right move
IDE-wise it is still unbeatable and rapidly catching up with AI development
Wouldn’t be surprised if at the end of the year their AI offering will be on pair or even better that the Cursor

Do you know why your Node.js app connects to `localhost 3000` for local communication?
That's called a TCP loopback, and there's a completely different way to start a server that doesn't use ports at all.
Let me explain both 🧵

~50% latency difference.
It is the exact number I got after doing testing with 2 types of sockets for Node.js server: TCP socket and Unix domain socket.
The TCP setup was done via TCP loopback, and the Unix socket was a simple socket file. The results are quite common ↓

I was interested in how Node.js handles networking when we create a new server or call `server.listen`
I dug through the source code and am now ready to show you how things are working from the inside, starting from the server creation and all the way down to kernel sockets ↓

At this point, starting a small pet project using serverless feels like the best option, especially with generous free tiers from AWS and the like.
Initially, I considered using Terraform to provision the entire infrastructure, but then I discovered AWS SAM...

Out of all the deep research features that I've tried so far, Claude is the best
They rolled it from Beta recently, and the results are amazing
It parses 500+ sources before getting back to you with results. Just because of the sheer number of parsed resources, it can't be bad

I've been playing paddle for the past month or so
Feels like it's easier than tennis and more fun since you have at least 4 people playing
The community is welcoming. One of the best activities for socializing that I've found so far

I feel like videocoding in its initial form is fading away.
People understand that AI won't create an app from scratch for you.
Instead, they focus on how to strategically leverage it to increase productivity by 20-30%.
That's a realistic goal.
