Broken link from

http://250bpm.com/

current leads to ribosome.ch, which is now a shop, rather than to

http://sustrik.github.io/ribosome/

which I infer based on authorship and style is the intended target.

The broken link was removed between:

https://web.archive.org/web/20170101000000*/http://250bpm.com/

and

https://web.archive.org/web/20171009164632/http://250bpm.com/

Typo in

http://250bpm.com/blog:93

dept instead of the probably-intended debt.
