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

@thomasfuchs I was curious where in the sky Andromeda is and how big it is, found this site: https://astrobackyard.com/andromeda-galaxy/

I wonder if it would be possible to capture it on a DSLR camera without a telescope (I have a 270mm lens)...

"a telephoto lens (or zoom-lens) will suffice" apparently yes! Waiting for a cloudless sky...

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

Oopsie...

PSA: #Linux 5.16 introduces an issue with #btrfs 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.

@hisham_hm When I'm where you are, what I do is start "ping 1.1.1.1" on the phone and then go and "tcpdump -i <interface>" on each "side" of the laptop forwarding to see what (if anything) is going on.

In your case I suspect you forgot ipv4/6 forwarding sysctl?

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 #cli 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?
