I admire the Go team's drive to improve build times. Many golang release announcements include bar charts—I wish more PLs did this.

TIL Tcl has a notion of 'safe interpreters', a mode where you can run untrusted code in a sandbox:

Not many programming languages have this, but it's way safer to include in the implementation than try to build as a userland library.
GNU Make defaults to a single worker, and newer build tools (e.g. ninja) default to the number of physical CPUs.I wish there was an option for 'leave me a little bit of my machine to do stuff'.
It's a small thing, but I'm much happier with the output of --version in the latest version of difftastic.
It shows the release version number, the commit hash, and the commit date. This gives you a sense of the age of release, but you still have a reproducible build (unlike build time).
It also shows OS, arch and compiler, because those are common requirements in bug reports.
