Installed an IRC client on my phone. The constant connect/disconnect as I was changing networks forced me to stare into the abyss that is IRC tooling such as bouncers...

ZNC looks nice so far

What happened to my Thinkpad? While the T440s never had an amazing screen (ghosting, brightness, etc), I've never observed such backlight issues before.

PSA: 5.16 introduces an issue with where btrfs-cleaner might "spin forever", cause 100% cpu load and issue a ton of writes [1]. My 256GB NVME drive got rewritten 10x over in less than a day before I figured out what's going on. There's a series of patches being worked out [2] but in the meanwhile what worked for me was turning off 'autodefrag' in /etc/fstab.

Looking forward to SQLite 3.38.0, JSON will become default built-in, and new '->' and '->>' JSON operators operators compatible with PostgreSQL and MySQL.

My favorite americanism: "ɜmɜnɜ" (IPA-ish) as a shortcut for "I'm gonna" which itself is a shortcut for "I'm going to". Desperately trying to shorten it up, not accepting that "I'll" is even shorter...

I find that the best way to experiment with new libraries with C API is using LuaJIT FFI. Throw in a bit of ffi-reflect [2] and inspect [3] and it's the perfect REPL combo to try out a new library (let's be honest, code extracted documentation a-la doxygen is rarely a good how-to guide).

Oh wow, this random shop I found is super friendly:

$ curl 'https://<domain>/shop/product-list' -X POST --data-raw '{"jsonrpc":"2.0","method":"call","params":{"ppg":1000,"pg":1,"category_id":2753},"id":0}' | jq '.result.page.products[] | {name:.name, price:.prices.new_price, features: [.features[] | {name:.name, value:.values[].name} ]}'

I just *had to* leave a mark on the internet that day, didn't I?

Getting closer, this time with a zoom lens...

Needs shorter individual shot duration (currently 5 sec might be too much) since the stars are still oval.

My first adventure into - Orion (+nebula visible).

Canon EOS 1300D with f/1.8 35mm lens, 15 min total time, 5s per image. Stacked with DeepSkyStacker, postprocess in GIMP.

I captured the usual lights + darks + flats + bias pictures, but shooting from my balcony clearly shows a lot of light pollution (+ neighbor deciding now is the best time to heat up with wet wood ruins a lot of pictures).

I need to get better with focusing, and maybe I'll try a different zoom lens later.

From me who runs a computer as a server home 24/7 for self-hosting 🙂 I should switch to a solar-powered Raspberry Pi like solar.lowtechmagazine.com/powe
