Vibe coding solves the wrong problem
Vibe coding gets the job done, but at what cost? The "boring work" AI replaces is where real understanding comes from.

This morning I got around to implementing stack frames. The change was rather simple and so was testing it.
Turned out, my instruction set was complete enough to verify if stackframes are there or not

The other day, I finally achieved something I've been trying for a long time: Implementing my own programming language.

Finally found some time to do some programming.
I had built a few applications with Cursor the other day, almost exclusively relying on the agent mode.
Getting stuff done with it is easy, but it's difficult to get into the code and make manual changes.
Its much easier to just have the agent do it

It's impressive you can get from zero to something working within minutes, based on a few sentences of vague description.
But it's not sustainable (yet) long term if you don't keep an eye on the changes

Using those AI tools for programming, I'm noticing it's easy to sit back and let them do the work.
But it's also a certain way to chaos down the road if the code becomes an absolute mess

I'm really impressed by cursor. The tool I'm working on right now I almost exclusively let cursor + claude 3.7 write the code. It's good overall but found a few corners where it kept generating methods over and over again that are never called

I used to draw a lot. Recently, I picked up the pencil again to come up with this after reading a blog post talking about the learning journey.
I enjoyed coming up with this, it was good practice.

I've been trying Cursor for a minute now and it's a mixed bag. For now, it saves me a lot of time with boilerplate. On the other hand, I lose all the savings because it keeps getting in the way with unnecessary changes and random glitches

I had originally used Redux for state management for coverletter.video. But I think I've reached a point where it just became very unwieldy.
I just started to convert the first components to zustand + react-query and omg it makes it much more maintainable.

My computer was about to stop working. Suddenly the "Force Quit" dialogue kept opening itself.
Once I read what it said, it turned out I had run out of memory. The list showed all big consumers, and the biggest one was Perplexity with over 100GB.

I found out about Perplexity the other day and it's such a productivity booster. It's able to browse the internet which is a big help.

Working video recording and video preview for Coverletter.video and I'm debugging the weirdest errors. For some reason a recorded video doesn't show in the video element, and instead it keeps giving me a preview of what's been recorded.

Currently working on an onboarding wizard for coverletter.video and I'm just grateful that I built user interfaces on Windows early on and I can transfer a lot of patterns from C# to TypeScript.
I'm using redux right now to manage state and it's very similar to MVVM /w WPF back then

we started building coverletter.video a year ago. At least that's when we started to build a first prototype.
Since then, it's grown quite a bit and came a long way in terms of design and features.
What really helped getting it off the ground: relying on boring tech.
