# 3 Linear Time

mathr.co.uk/blog

is my blog, no longer updated.

# 4 Social

post.lurk.org/@mathr

is my microblog on the Fediverse.

# 5 Code

https://code.mathr.co.uk hosts some of my git repositories. I code a lot. Too many bad robots, so web browse is forbidden. Using the git tool to clone repositories should still work ok.

Some projects are also on Codeberg: https://codeberg.org/mathr
