Erlang Solutions: Guess Less with Erlang Doctor
BEAM languages, such as Erlang and Elixir, offer a powerful tracing mechanism, and Erlang Doctor is built on top of it. It stores function calls and messages in an ETS table, which lowers the impact on the traced system, and enables querying and analysis of the collected traces. Being simple, always available and easy to use, it encourages you to pragmatically investigate system logic rather than guess about the reason for its behaviour.

I completely forgot that DVD-RAM was a thing once. Found my old disks and they still work. 🤯 The data on them is from 2008, so they’re not that old. Still impressive.

The disks are two-sided. On the photo, that particular side of the disk on the left appears to be completely unused. 🤔

And then I read on Wikipedia that DVD-RAMs aren’t produced anymore at all today. Huh.

(I refuse to tag this as “retrocomputing”. Read/write DVDs that you can use just like a harddisk, thanks to UDF, are still “new and fancy” in my book. 😂)
