that feeling when you're tracing code to find out why value changed somewhere between the lasagna layers and you find a custom scripting language you weren't aware of

#softwarearcheology

Someone extracts the oldest surviving copy of UNIX from the tapes Warren Toomey had been given by Dennis Ritchie in 1997, after Ritchie had already stored them for 25 years (!), and gets a 53 year old operating system running on a PDP-11/20 emulator.

Mindblowing

If you are interested in the proper usage and concepts of #subversion (or #svn) I can highly recommend this book. Pragmatic Version Control using Subversion, by Mike Mason.

I was digging into version control history during the holidays, as I started using #jj aka #jujutsuvcs in addition to git and wanted to know more about the concepts it is designed with. I had the luck of being able to start my version control life with git, so I never worked with Subversion a lot (some people might say fortunately). But as many people seem to hold it in high regard, I wanted to understand why.

This books takes you through all you need to know to use it. As an "normal being" just using it. Handling normal things, releases, branches. But also from an administration side, handling and organizing repositories. Backing them up. Splitting and uniting them.

And all of that written in a very enjoyable way.

As one does between the years, I have started digging into #subversion (the version control system) to learn more about its concepts. Because, why not? At least it helps me to be grateful for the ease of use I have with #git (sorry subversion...).

In case you want to have a look, I built a #vagrant setup to easily play around with Subversion:

As I am on a reading spree, #Mercurial will be next. And no, before you ask, I will not get into CVS after that...

I really enjoyed this post by @chadaustin where he goes deep into the history (and related mistakes) of introducing 8-bit and 24-bit support in SGR sequences. Fantastic blast to the past!
