While it's been coming for a long time, it's still frustrating to see the cgi module go. It's going to create a load of busy work to rewrite some low-traffic scripts. Modules being removed [edit: in 3.13]: https://

This is a great video. A summary for those who don't want to wade through it: The main message is that if the knot is slightly loose, or messy, the strands pinch unevenly in a fall, and it can be really hard to untie (depending on the

I used to use `unbuffer` which comes with expect, and might be what you used too. I now use the following hack, which works faster: Create isatty.so like this: echo "int isatty(int fd) { return 1; }" | gcc -O2 -fpic -shared

There's also math-inclined partner juggling. See the "social siteswaps" DVD, and https://passist.org/ for example. Oh, and of course: https://www.juggle.me.uk/passing/ (RIP Aidan Burns)

For juggling in particular, it's also my experience that teaching complete novices is easier. People who've juggled a bit often listen less, and get frustrated with breaking things down, and just go back to doing what they know. A

I originally learned to 3 balls from the Klutz juggling book as a kid, and still have largely fond memories of it. I have a slight sour taste from the very end of the book, which discourages people from trying to go to higher numbers such a

Numerical implementations of functions often use look-up tables, and there's sometimes a trade-off between number of operations and memory access. (Large look-up tables aren't cache-friendly.) This blog-post is from someone who pr
