Here’s an example of what I mean, an interactive svg-only graph: https://gist.githubusercontent.com/ruuda/b84e94c3394f740d05b...

I was hoping this was something interactive using only svg. For example, one can do interactive charts with moving tooltips and a vertical cursor etc. fully in svg, using only hover states. (I thought Pygal [1] did this, but now that I chec

There are two types of software: those that everybody complains about, and those that nobody uses.

Not exactly, but it looks similar. With what I was talking about you can have as many versions around as you need. An example would be using (TVar (HashMap k v)) in Haskell.

Here's one design that's nice to do for servers in GC'd functional languages, and hard to achieve without GC. Have the state of your application be a persistent data structure (one that you can efficiently update such that bo

How recently? I remember there was a referendum to make the age equal in 2017 or 2018, but the proposal was rejected at the time.

The new Nix command syntax that was there up to 2.3 was always marked as experimental, but it worked fine for many years, I used it in many projects ... until it got deleted and replaced with flakes. I really hope they don't do that ag

Imagine this happened a few years ago, and the EU had instead demanded micro-USB. Then we would still be flipping plugs twice, and I wouldn't be able to use my laptop charger to charge my phone. It's not clear to me that USB-C is

The input is 9139 lines long, each anomaly probably occurs dozens of times.

It is built by https://lumi.guide/portfolio-items/p-route-bicycle-utrecht/ , I just happen to know some people who worked there. The Haskell community is pretty small :)

Fun fact, the signs that show how many parking spaces are left run NixOS!

Yeah exactly, generate json instead. I now have some GitHub Actions config in Python, and some in Nix. Nix is actually really nice for this. Like yaml it has less line noise than json and it support comments, but unlike yaml the language is

It also regularly repeats the same line number. E.g. it numbers them 120, 121, ..., 131, 132, 120, 121, ...

Also a fun one is the "on" key that specifies when the workflow should run. "on" is magic in yaml, and some implementations will convert it to the string (!) "True" when it occurs as a key (I'm not talking

If you use MPV, you can pass it ffmpeg filters, and ffmpeg has many ways of compressing the dynamic range. See [1] for the set of audio filters. Here are the settings I use [2]. If you can't run your video through ffmpeg, I guess you c

The result is one bit wider, so it does not overflow.

The comment in part I that b-trees are not appropriate because Git does not do “live updating” of the packfiles also felt a bit misplaced to me. Writing small objects and then aggregating them into larger ones when we get too many of them,

It works fine for applying the patch, but then you have to manually follow all of the build steps, turn it into a distribution package, etc. With Nix it is easy to edit an upstream package that already knows how to build the software, to in

by ruuda 4y ago
If the upstream project does not want to merge your fix, but it's an obvious improvement and a non-controversial patch, then one option is to have packagers carry the patch instead. For example in Nixpkgs, it is quite easy to patch an

Yes, that's a fair summary. Performance is not something I'm worried about for my app, maybe a few dozen people would use it at the same time, and I run everything at serializable isolation level anyway. But I can imagine that for

This looks nice, but it doesn't enforce in the schema that all transaction lines sum to zero. Is that a problem in practice? Or is it one of those things where if you get it wrong, you tend to notice immediately because everything brea

I would like to know about this as well. I struggled with this for a while for a prediction market app that I'm building. Eventually I ended up with [1]. I am somewhat pleased with it, but it does feel unwieldy to work with. I have som

I wonder, when sampling to shrink the set of bad titles, it samples uniformly. But wouldn't it be better to take the n worst titles (with the least upvotes)? After all, titles near the good/bad threshold are a bit arbitrary and sh

Well, can you imagine how much more upvoted it would have been with a good title?
