I recently discovered gojq at work. I was looking to see if there was a pure Golang implementation of jq as a library to use from within Go code. Then I compared performance to native jq to make sure that it wouldn't be too much slower than the original when embedded in Golang.
It ran my complex jq script in ⇔ the time over the same data.
That was a nice free speedup!
Now my ~/bin/jq is a symlink to

Listened in to the Academy Software Foundation's virtual townhall about the Open Review Initiative. I knew that project because they provide very useful ffmpeg command lines and they're doing all the encoding tests to figure out good quality settings and obscure parameters.
Learnings from the presentation: prores by ffmpeg is sadly pretty crappy compared to the real prores from Apple. There's the OpenAPV codec that is gearing up to be an open-source alternative:

Woof. This made my brain hurt over a few weeks between delighting customers, but I persevered.
Firecracker is the tiny, lightweight VM technology behind AWS Lambda "serverless" Function as a Service. You can run these tiny, tiny, fast VMs on-premises if that solves a business problem.
Anyway, here is an actual working tutorial that I wrote as most of the major tutorials out there did not work for me. Enjoy.

I just drafted two more chapters for the PSI spec, on microprocessors and peripherals. Small and slow steps lead to the ultimate unterstanding of #compute #platforms. 🥳

Mastodon 4.4.0 looks interesting:

Since DJV went into a hiatus, I have tried #mrv2 more than once but it wouldn't do. Brought down my whole Linux desktop last time I tried, just by showing/hiding certain parts of the GUI.
So I've compiled #OpenRV but I really want something that loads faster than that clunky old player (even…

Really fast boot. Not for me. I'll stick to containers and the odd KVM VM using virt-manager.
