<p>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?<p>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.</p>

<p>I usually write my user documentation using DocBook. For my recent applications built on top of Qt (e.g. PaletteWB (www.palettewb.com)), I needed something that generates in-app help pages. db2qthelp does this.<p>Any criticism or interest is appreciated.</p>

<p>Hello there!<p>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.<p>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 fractions and optional interpolation. That's fine. But usualy indices with more or less than 256 entries are not easy to understand, as colors get pruned or do not show up...<p>Second, the fact that you can have up to 65536 color entries does not make life simpler, in contrary. Some of the algorithms, like e.g. repetition patterns (which already were on HN, <a href="http://www.krajzewicz.de/blog/stretching-the-c64-palette.php" rel="nofollow">http://www.krajzewicz.de/blog/stretching-the-c64-palette.php</a>), easily generate vast palettes. How to limit the user, here? One implemented solution is that you have to set a maximum palette size using an extra option in the settings... Are there better ways?<p>And, third, what is the best way to promote it - besides posting it here?<p>Sincerely,
Daniel</p>
