did you apt update beforehand ? it is weird that it’s trying to install lower level libc6

before getting a pocketbook I was using ReadEra and it worked alright (for badic reading)

don’t know the details but my general IT knowledge says that: single unicode character/glyph can take up to 4 bytes instead of 1 (ascii).

have been eyeing elixir for a while, should give it another try. the whole beam/otp/erlang is a bit scary though

Little bits and pieces but mostly bug fixes - I like my shit working but maintenance is not my strong suit, more of a traveling contributor or drive-thru fixer.
I believe I fixed calling in one electron messenger.com wrapper before - that was fun but these days I usually try to help the game BAR whenever I have extra time.

Edit: Keep forgetting but I am also maintaining few apps on AUR, nothing big except for maybe one helper tool/calculator for EVE online

Linux has kind of two forms of memory pages (entries in RAM), one is a file cache (page cache) and the other is “memory allocated by programs for work” (anonymous pages).

When you look at memory consumed by a process you are looking at RSS, page/file cache is part of kernel and for example in btop corresponds to Cached.

Page cache can never be moved into swap - that would be the same as duplicating the file from one place on a disk to another place on a (possibly different) disk.
If more memory is needed, page cache is evicted (written back into the respective file, if changed). Only anonymous pages (not backed by anything permanent) can be moved into swap.

So what does “PostgreSQL heavily relies on the OSs disk cache” mean? The more free memory there is, the more files can be kept cached in RAM and the faster postgres can then retrieve these files.

When you add zram, you dedicate part of actual RAM to a compressed swap device which, as I said above, will never contain page cache.
In theory this still increases the total available memory but in reality that is only true if you configure the kernel to aggressively “swap” anonymous pages into the zram backed swap.

Notes: I tried to simplify this a bit so it might not be exact, also if you look at a process, the memory consumed by it is called RSS and it contains multiple different things not just memory directly allocated by the code of the program.

Had to solve the same problem few months ago, user provided content and so, user provided translations.
We use postgres everywhere and we had to support 3 languages initially with one more eventually, so we decied to use json fields for anything that could be translated (which wasn’t too much). Mind you, this was basically a (temporarily permanent) prototype project but (fresh) postgres has a good support and operators for json so it worked alright.

EDIT: I remembered that hstore might be a good alternative too, I think it was slightly less “heavy” and had better operators for the kind of access we needed

keychron? most of their kbs can be ordered barebones

it’s not just Let’s Encrypt, it’s because of https://certificate.transparency.dev/

Flameshot: screenshotting tool with everything you would ever need for screenshots

have it on dietpi (pi 4) + tailscale at home to monitor my dedics

Best bet would be that something reloaded/changed the underlying ip/nftables bypassing ufw (ufw is just a frontend, I do not know if it periodically verifies the current rules are correct and it would feel extraneous to me if it did). Or it didn’t apply it correctly.

You can get the actual rules with iptables-save (dunno about respective nftables command)

If your primary usecase is going to be music (so a need for realtime capabilities for stuff like recording, VSTs and DAWs) then I do not reccomend immutable distros for a simple reason: you will probably/eventually need to hack something up to get it to work and at that moment, the immutability is just extra work.

As far as I have tried fiddling with the music stack on Linux (which is not that much), the whole pipewire/JACK/carla stack is a bit messy and I can’t imagine it working with flatpacks due to the sandboxing/permissions.

in that case you can grab any of the other distros that are Arch-based, EndeavourOS/Garuda/CachyOS and so on. You will get the benefits of rolling-release like fresh-er software without the need to setup & configure it yourself.

One is trying Bazzite the other one is just classic fedora

Two of my friends switched recently.
They had none to very little experience with anything Linux before, their previous win11 installs just over bloated and the copilot bullshit pushed them over. Both (indie/non-pop shooters) gamers btw.

This is the year of linux.

Unsure how well known it is, but flameshot (screenshot tool).

I prefer CLI usually, so: zoxide, the zsh git plugin for aliases (e.g.: gst is git status), fzf zsh plugin and the tldr command comes in handy sometimes.

Also, this might be useful just for me, but due to orientation of my living space, I have to fiddle with monitor brightness at least three times a day so I made myself a little Qt tray wrapper around ddcutil’s ddcquery which can change standard vesa monitors brightness/contrast (DDC/CI communication).
There is also ddcui/gddccontrol GUI that does the same thing.

For cli oriented folks, ncdu is a great cli alternative of QDirStat

Friend just hopped to Bazzite from Windows.
I was hoping the atomocity would be a great boon - you kind of can’t break it right.

Well, he wanted to configure RGB lighting on his mouse but the flatpak openrgb did not work, supposedly the udev rules included in bazzite by default, are not up to date or there was some other problem.
As such we had to install openrgb the usual system-wide way, with rpm-ostree in terminal - something I was hoping he would never had to do.

Unless the vendor is rolling something super custom, for the communication TO the keyboard, it should use USB HID.

Start Wireshark, filter for hid, connect the KB and the first message should be a HID descriptor of the KB, look for Output Reports (it’s meant from the POV of the usb master) or Feature Reports.
Though, this will probably not yield much insight - vendors love to do the easy thing, reserve opaque 32x8 bytes as a “downlink” Output communication in the Vendor Usage Page and stuff their own protocol/encoding in there.

On linux I can recommend hid-tools for working with this, in windows I believe your only solution is Wireshark.

Happy Hacking!

E: About the already reversed software, for logitech (and more) stuff, there is piper but you will want to look into the underlying daemon libratbag, there is also solaar
