Support? It's just showing weaknesses of LLM's. Which is a valid sort of research I would say?

New comment by jurgenkesker in "Ruby 4.0.0"

jurgenkesker — Thu, 25 Dec 2025 10:44:09 +0000

This year I also switched from Ruby to Kotlin on my hobby/light commercial backends. I just can't stand the way Ruby is not statically typed, and the resulting insecurity around if everything is actually doing what it should do. Kotlin gives me joy, and performance is actually better (trading memory requirements ofcourse, but that's not a big problem anymore). I still love Ruby, but only use it for simple scripts now.

I indeed really liked Ruby because of it's expresiveness, it being totally OO, the lovely readable and writeable syntax.

But yeah, that was 20 years ago. These days I find Kotlin to be the perfect fit for my projects, because of the static typing and its ergonomic syntax. I just don't feel confident about Ruby projects when they start growing. But, I still love the language, although mostly for small things.

KVM is just your Linux Kernel Virtual Machine. So you can manage VM's on Linux. It is not related to Docker.

I recently opened Pinterest after a year or so, and did look for some nice architecture / houses, and all results had the tag 'AI enhanced'. No I don't want AI houses, I want to see real architecture! Even though the tags are there, you can't filter on 'No AI'. So I stopped using it again.

So yeah, this is only really relevant for collecting logs from clickhouse. Not for logs from anything else. Good for them, and I really love Clickhouse, but not really relevant.

jurgenkesker — Mon, 09 Jun 2025 13:12:06 +0000

Yes, I would think that would work better indeed. As a augmentation or help tool. I would love to be able to say to MyFitnessPal that 'I ate this and that food, same as usual, and oh yeah drank this.' Just as a easier input interface. I wouldn't trust a pure AI solution without some proper database behind it.

Did you verify it sometimes how accurate it is? I would be wary of it to be honest.

Ah yes, and every small Android dev is banned from Play and Admob for tiny unknown reasons, with no recourse or way to communicate with Google. But Meta here probably won't get any problems at all. They should be temporarily banned!

Very well rounded and grounded article. Like it very much!

Indeed as someone else in the comments said, the personal touch is the best asset you have as indie. So talk with your customers.

I run a Android app, next to my day job, and I pride myself on always putting the customer first, and actually fixing their pain points or implementing their suggestions. Empathy is so important, and something a big company will struggle with.

I'll checkout the recommended books!

jurgenkesker — Tue, 22 Apr 2025 17:52:15 +0000

I really like Clickhouse. Discovered it recently, and man, it's such a breath of fresh air compared to suboptimal solutions I used for analytics. It's so fast and the CLI is also a joy to work with.

New comment by jurgenkesker in "Great things about Rust that aren't just performance"

jurgenkesker — Sun, 12 Jan 2025 18:56:04 +0000

I enjoy Rust, but have settled on Kotlin for my language of joy. I use it in my day job for Android, but also recently started converting personal project backends and APIs to it (mainly from Ruby). I really like the ease and joy Kotlin gives me, and if I need a very high performance or very low level project/library, I'll write it in Rust. Rust is too slow for me (when coding), so a bit too low level I guess. In Kotlin I can express everything I want.

Agree, we have some time in sprints to do whatever we want, and then you finally can fix those minor annoyances that are probably the users annoyance too. But in general I think more time should be there reserved for it. It's now once in x sprints.

When working on my own apps it's really obvious that non focused time leads to lots of improvements. Instead of only the business wishes. In that regard it seems that the potential of a dev is a bit diminished when you don't have time to do things according to your own priorities.

jurgenkesker — Tue, 12 Mar 2024 10:44:56 +0000

Or just use Clonezilla? Then you also copy only the actual data blocks, and it can autoresize your partitions as well. That's how I always do it.

True, I do always just take the NVME disk out of the laptop and put it in a highspeed dock.

New comment by jurgenkesker in "Options for genuine ECC RAM on the desktop in (early) 2024"

jurgenkesker — Sat, 17 Feb 2024 17:44:00 +0000

Normal Asrock Ryzen 5xxx motherboards also supported ECC, I used ECC RAM for my homesever with a normal 5900X and a Asrock B650M Pro4 motherboard.

The new Asrock Ryzen 7xxx motherboards unfortunately don't have that same ECC support.

Seeing there is no business model (or did I miss that?), how likely is it that this app is sending installed app lists to 3rd party for appstore analytics like Data.ai and similar services? Something needs to pay the bills?

New comment by jurgenkesker in "Thoughts on PostgreSQL in 2024"

jurgenkesker — Wed, 03 Jan 2024 00:12:06 +0000

Wondering why nothing is said about compression? For MySQL you have Rocksdb with high ZSTD compression. Is the Postgres solution to just use compressed filesystem like ZFS? I could not find much info when researching Postgress, except for Toast compression, which didn't seem very strong.

I have a huge DB which would take many TB but now runs on a 500GB footprint. Thanks to Rocksdb/MySQL. Pondering a move to Postgress, but seemed like a step down in this regard.

Currently around that price indeed on Steam Sale, and lower if you only look for Spy Fox bundle or Put Put or whatever you want. Very nice.
