Re:Ask HN: AI Depression on Friday February 13, 2026 @11:30AM (#47004555)
What I find really disturbing is the impossibility to catch up with the development - which agent system to use, which model, what are the right models for what tasks?

I do not fear that some agents will pollute my repos with their PR. In opposite, I suppose that we will end at a point where for each question, task, or problem, one will find many (AI-coded) solutions, making it impossible to choose a right, solid, reliable one. I recently thought about having a database of tools per task so that a comparison would be possible. But the maintenance costs of something like this are enormous when including benchmarks, comparisons, etc. on different qualities.

Hello there!

I though this may be interesting for linguistics fellows...

DBSCAN for grouping locations. Well, still slow...

Some recent tools, finished/improved this year:

- db2qthelp — a DocBook book to QtHelp project converter (https://github.com/dkrajzew/db2qthelp)

- grebakker: a private backup tool (https://github.com/dkrajzew/grebakker)

- gresiblos: a tiny static site builder (https://github.com/dkrajzew/gresiblos)

Currently, I work on a Desktop GLSL shader editor. Looks fine so far...

Hmm, my dollar: http://www.alsog.de/

Or see the examples page: http://www.alsog.de/feat_examples.php

Nope, but HackerNews get interested in one tiny blog article on c64 palettes some years ago: http://www.krajzewicz.de/blog/stretching-the-c64-palette.php
I like my web type setter written in Python very much: https://github.com/dkrajzew/degrotesque

It replaces common ASCII characters by their typographic counterpart, e.g. "Hello - I'm back" will get "Hello — I'm back"

:-) You insist...

Yeah, look, it's hacky, yes, and maybe runs only with a certain setting.

But, well, you may be right, when I think a second time about this. Thanks...

Yes, I know. But DocBook generates fine HTML and HTML is what QtHelp shows.
Oh, sorry, SUMO is a traffic simulation for research purposes.

Show HN: PaletteWB 2.0.0 Released

http://www.palettewb.com/

Hello there!I build a tool for playing with color palettes. I know, it's not really the first one but there are some special features, I would like to talk about.First, it supports not only 8bit palettes, but also ones with up to 65536 indices. And floating point palette indices. Now, floating point indices are smooth - the palette is stretched along the value range of 0.0 to 65535.0 including...

When being interested in traffic simulations, you may try https://www.eclipse.org/sumo/ as well.
Yes, I'd confirm that it's sufficient to say the truth :-) I like one of my pages (you have to scroll to the bottom for the legal stuff): http://www.palettewb.com/

Re:Conventions for Command Line Options on Saturday August 01, 2020 @04:04PM (#24023454)
Hello there!

Yep, it's some kind of an advertisement, but for an open source project.

I made some experience with parsing command line options when working on an open source traffic simulation named SUMO (http://sumo.dlr.de) and decided to re-code the options library. It works similar to Python's argparse library - the options are defined first, then you may retrieve the values type-aware.

You may find more information on my blog pages: http://krajzewicz.de/blog/command-line-options.php

The library itself is hosted on github: - cpp-version: https://github.com/dkrajzew/optionslib_cpp - java-version: https://github.com/dkrajzew/optionslib_java

Sincerely, Daniel
