 Time measurements taken with the [time](https://man7.org/linux/man-pages/man1/time.1.html) tool, using 1M samples. But different implementations use different algorithms and, occasionally, different time measuring methodologies (for the C, Nim and Lua implementations, I run the program 100 times and take the mean). Their speed was also measured under different loads in my machine. So I think that these time estimates are accurate within maybe ~2x or so.
 
-Note that the number of lines is much shorter for Squiggle and SquigglePy because I'm just counting the lines needed to get Squiggle and SquigglePy to output a model, not the lines inside them.

 Although the above paragraphs were written in the first person, the C code was written together with Jorge Sierra, who translated the algorithmic improvements from nim to it and added the initial multithreading support.
 
+### squiggle.c
+
+squiggle.c is a minimalistic version of squiggle focused on understandability and being self-contained. You can see the code [here](https://git.nunosempere.com/personal/squiggle.c), and the code for the specific example [here](https://git.nunosempere.com/personal/squiggle.c/src/branch/master/examples/02_many_samples_time_to_botec).

 ### NodeJS and Squiggle
 
 Using [bun](https://bun.sh/) instead of node is actually a bit slower. Also, both the NodeJS and the Squiggle code use [stdlib](https://stdlib.io/) in their innards, which has a bunch of interleaved functions that make the code slower. It's possible that not using that external library could make the code faster, but at the same time, the js approach does seem to be to use external libraries whenever possible.
