I am pressing them by accident when scrolling

Because I express my creativity through shitcode, I named my development hardware appropriately.

It's actially xn--og8h8z because /etc/hostname is allowed to contain only ASCII Latin characters, numbers, and dash, but converting emojis to Punycode using command idn 🌈💩 does the job.

I can log into my Raspberry using command ssh user@🌈💩 however Bash login shell still shows untranslated Punycode hostname instead of rainbow poop symbols, so the support is not yet fully there, and avahi-resolve-address shows hex codes of UTF-8 emojis.

I'm using Debian 13 btw.

When I open Lemmy Connect, I see this. No frontpage posts are loading, however I can open my profile and read my own posts.

I am posting this from a mobile web browser like a savage. Please help!

Components:

• ESP32-S3-Zero with RGB LED. I've selected it over more energy efficient ESP32-C6 because bigger chip looks better, and it's placed symmetrically.
• two CR1220 3V batteries.
• copper wire from Ethernet cable (single-strand obviously).
• lead-free solder (it's a ring, don't wear lead on your fingers).
• hot glue gun, because I could not make a battery holder using just wire.
• a piece of small diameter heat-shrink tube for copper wire.
• a jewellery file (optional, only needed if you actually going to wear the thing).

Instructions:

• flash the firmware first, because batteries will obstruct the USB port.
• it is recommended to file off all sharp edges on the board before you start soldering, it will be harder to smoothen the edges afterwards without scratching the copper wire.
• smoothen your wire, wrap it around some finger-size object like a tube of flux, cut the wire spiral into rings.
• solder wire rings into one side of the board, use every hole except for 5V and GND, and TX/RX on the other side.
• put the board onto your finger, measure and cut the other side of the wire rings to match your finger size, solder wire rings to the board.
• Glue two batteries together in sequence, then glue them to the top of the USB connector. Watch out for polarity - CR1220 has positive charge on the body and negative charge on the contact plate, you need to put the negative electrode onto the USB connector.
• wrap a stripped copper wire around another wire with isolation on it.
• bend both wires so that the stripped wire will go into 5V hole, and the isolated wire will go into GND and RX holes. The isolated wire is only needed as a mechanical support, because you should not solder another end of 5V wire to the TX or RX hole, or you risk frying the chip.
• add a piece of heat-shrink tube to the stripped wire. You need to make contact with the battery at the top and prevent the wire from contacting the battery at the bottom. You can try to leave a bit of isolation on the wire, but it's easier to use the tube.
• solder wires to the board.
• do not to make a common mistake of connecting 3V3 and GND together, or GND and 5V, like I did. 3V3 wire goes under the board onto the finger, GND wire goes above the board to hold the batteries.
• keep wire ends from sticking out of the mounting holes when soldering, they are going to scratch you when you wear the ring. You can file them off afterwards, but it's easier to not make them stick out in the first place.

Firmware: https://github.com/pelya/esp32-led-cycle-colors

The only thing it does is cycle LED with random colors. It shuts off power by pressing BOOT button or after 5 minutes. To turn it back on, press RESET button. There's no WiFi, Bluetooth, or LCD screen, but at least the LED is bright.

I did not measure how long will these two batteries last. When they are empty, I'll need to rip off hot glue blobs from the board, which would be pretty easy since I only put hot glue onto metallic surfaces.

And it's absolutely not waterproof, hopefully the finger grease will keep to the underside of the board and won't short the battery.

I am sorry, two random Internet users in Korea and Germany, your IP addresses are simply special.

Google had removed my X server app from Play Store, because it was too old (is 2022 too old?)

But no more! I have recompiled it for the newest Android version and published it back. And you can use it to run GUI apps from Termux. Launch X server first, then run these commands in Termux, then switch back to X server:

pkg install x11-repo
pkg install xfce4
export DISPLAY=127.0.0.1:0
export PULSE_SERVER=tcp:127.0.0.1:4713
xfce4-session

Termux now has it's own X server, my app is pretty similar, except that it's landscape by default.

I have mixed sour cream with Marmite to make it spread more evenly over banana, and the taste is... not good. The salt overpowers all other components. It's even worse than plain Marmite banana, because you can actually taste the banana before Marmite diffuses over your tongue. The best combination was cream banana without Marmite, to no surprise.

Marmite cream oat cookie is a surprising discovery. The overpowering saltness of Marmite is balanced by the overpowering sweetness of the oat cookie, the same way salted caramel works. I don't think the cream is even necessary, you can rub Marmite on the cookie's hard surface much easier than on the soft banana.

If combining two things from a fridge could be called a new recipe. It tastes good, I promise.

The shop also had regular sprink bottles with the same cologne, but this bottle is shaped like a fuel can, so it looked manlier to me. It contains 80% alcohol, so it's also a disinfectant and an after-shave.

I don't need any fancy tiling window managers. One fullscreen window per desktop, and 12 virtual desktops, that was my workflow for 10 years. Then I incorporated KDE activities into my workflow, which are exactly like virtual desktops but switched with Meta-Tab not with Ctrl-F1 - Ctrl-F12. Wonderful!

And then, Plasma devs broke it. Switching activities now puts my foreground fullscreen window (one per desktop) into background, and switches keyboard focus to the desktop. Give me back my keyboard shortcuts, and you could also rename Plasma back to KDE while you're at it, thank you very much.

At least there is a bug opened, but it's doubtful that Plasma devs will fix it before Debian 13 release. I can't even find motivation to update my OS anymore.

Also works for searches 'Times new roman' and 'Courier new font', but not for 'Lucida console font' or 'Dejavu sans font'.
