I just completed all 12 days of Advent of Code 2025! #adventofcode https://adventofcode.com/ Day 9 part 2 and Day 11 part 2 were hacks custom coded to the particular problems, but it worked in the end!

I learned that my #openstreetmap planet.osm.obf snapshot that I have processed in my Postgis does not yet have the features that I'm interested in; they've been added relatively recently. Nooooo... Anyway, guess who's downloading another 86GB on an old DSL connection?

It's quite cold outside, but seeing Orion just above the horizon I had to pull up the camera and climb to the roof. While I was waiting for the exposure, I saw a "falling star", so the frozen fingers were worth it. #astrophoto

For some reason image-only content warnings on my homeserver get their CW removed. When posting text-only or mixed text + image CW then the CW gets applied, but if I post image-only + CW then the CW does not get applied. Good to know! #mastoadmin

#adventofcode Day 9 - Nasty [hint]

Today my 5yo showed me that there's a THX-sounding goat horn in #minecraft

Train service in Austria Sitting in otherwise smooth ride I noticed a little bit stronger shaking, so I pulled out my phone to check the speed. The train is trying to cancel a 6 minute delay on a 9 hour trip. Which I'm thankful for, since I don't want to miss my followup connection :)

Just lost the #whamageddon I went all the way through the christmas markets in city center only to lose while browsing a shoe shop...

Heard news about upcoming RAM price increases, saw DDR5 prices increase 200% over few months ago everywhere... Then I found a store that still forgot to increase prices for a lower-rated 5600 CL40 sticks, so I grabbed 64GB out of FOMO. I guess I'm building an AM5-based machine soon.

I think I'm pretty happy with the result of replacing the screen on my #thinkpad T440s to "B140HAN01.1 1NV140FHM-N41 N140HCE-EAA 14'' Lcd screen For Lenovo L440 T440S T440P T450 T450S IPS 1920x1080 HD Laptop LCD Screen FHD IPS 45NTSC, 14.0INCH": - More consistent backlight - More vivid colors - […]

I was looking at #3dprint #itx case and found this nice looking project from 2018: https://eclecti.cc/hardware/fully-parametric-3d-printable-computer-case The name looked a bit familiar, so I checked the project page: https://github.com/eclecticc/ParametricCase And indeed - it's from the […]

Could you boost this post for copious Federationings? No reason. I just love watching the fediverse go brrrrr (and my server go aaaaa) :drgn_sparkle:

RE: https://toot.kottman.xyz/@michal/115220577218654094 $ uptime ... up 49 days, 11:04, 3 users, load average: 2.15, 1.81, 1.66 It turns out no proper wiring is required, it's powered straight from aligator clips as pictured.

I've spent way too much time investigating why my #ws2812 RGB LED strip driven by #esp8266 with #wled firmware is only lighting up roughly half way. I was checking wiring guides and signal strength, modding the level shifter as per […] [Original post on toot.kottman.xyz]

The intentions, the nuanced hints, the subtle nudges are somehow not getting through #cats

What is my #esp8266 trying to tell me? Did I give it brain injury by some unexpected overvoltage somewhere?

The main gripe I have with #lua is not the 1-indexing, not the non-"mainstream falsiness", not the "weird" definition of table/array length, not the keyword-based lexical blocks, not the global-by-default... But the fact that relational operators are not as virtualizable as e.g. arithmetic […]

ZIP archive created in 2024, using an encoding I last saw when I was a kid. The things I have to deal with...

I'm trying to upgrade the screen on my #Thinkpad T440s. I'm following this guide: https://www.ifixit.com/Guide/Lenovo+Thinkpad+T440s+Display+(Full-HD+no+touch)+Replacement/63644 The guide did not mention one crucial detail - that the screen background is […] [Original post on toot.kottman.xyz]

A very useful #3dprint that allows the Parkside 20V tool battery to power my DIY boom box: https://www.printables.com/model/404396-lidl-parkside-battery-20v-xt60-adapter

Hafo kafo => happy end

I thought I had a bunch of ESP32-S3 Zero boards in my parts drawer, but it turns out they are RP2040 Zero, and I need the wifi :-(

Typical... #aurora everywhere, people posting beautiful pictures, but no, we'll be getting low clouds and light pollution instead...

Finally managed to get #wled firmware working on a good old #esp8266 board that was lying in the part box unused. I need more #rgb in my life!

#aurora ribbons from cockpit of a flight heading to Fort MacMurray #alberta as major solar storm hits earth.

I was testing out the "Mini 560 PRO" buck converter (the 5V voltage started breaking down past 2A of load) While doing that my BT-305 power supply started smoking! It was delivering just 500mA ish at 12V so not that much power...

The feature I like most from #mastodon 4.5 is actively pulling comments from posts I'm reading, not just showing the ones that happened to fly by my homeserver.

I'm trying to unlock a #xiaomi phone bootloader, I already have their social network account with 30 days of activity, and I have the option to unlock the bootloader. But apparently there are daily quotas, that open up at midnight GMT+8. I missed it by 5 minutes, and apparently the quotas for […]

I'm using #mautrix to bridge family #whatsapp chat groups to my #matrix instance. I noticed that I'm missing a few weeks of messages. I checked the logs and found an error message. A quick web search later I found a FAQ entry which contains the error message verbatim, what it means, why it […]

My wife needed help installing an app on her laptop, so I'm compiling a recent version of glibc... A day in the life of #linux user

https://www.tomshardware.com/pc-components/storage/server-dram-prices-surge-50-percent I guess I'll have to wait with the upgrade until after the crash then...

I bought a portable 14" monitor which connects over USB-C and HDMI, to help with setting up my SBCs (manually setting the focus on Pi camera lens over network is very inconvenient due to the latency). I gave it to my wife as an extra monitor for her 4yo laptop running stock Ubuntu 24 LTS. I […]

#immich added OCR in v2.2, this will take a while...

Yesterday I banged my middle finger on left hand by a rock, and today I was complaining to my wife that I think it feels colder than the other fingers (it doesn't hurt now and I can still feel everything). She said I'm only imagining it but thermal camera tells a different story.

When you're so bleeding edge (VLLM) that not event the latest official driver (intel oneAPI) is fresh enough: /opt/intel/2025.3/compiler/2025.3/lib/libur_loader.so.0: version `LIBUR_LOADER_0.11' not found (required by /code/vllm/.venv/lib/python3.12/site-packages/torch/lib/../../../../libsycl.so.8)

Why is this now considered "normal"? $ curl -LsSf https://astral.sh/uv/install.sh | sh (this is not a curl rant!)

Memories were not working for me in #immich, and issues like https://github.com/immich-app/immich/issues/23239 are being auto-closed by a bot as duplicates without specifying duplicate of *what*... But I found out you can trigger memory generation manually […] [Original post on toot.kottman.xyz]

> With just 8 bits [per color channel], you have more 9's than AWS this year! Burn. Seen in comments on HN about dithering.

Why did we standardize on Ah (mAh) as the metric for "capacity" of battery storage (phones, power banks)? Wh (mWh) would have been a lot easier to reason about.

I was building the Adafruit 3D printed case for my #RaspberryPi 4 + HQ Camera. https://www.printables.com/model/32718-raspberry-pi-hq-camera-case I only have M3 and M2 standoffs / screws. It turns out the Pi uses M2.5 (!?!) - the M3s are too thick, and my […] [Original post on toot.kottman.xyz]

I accidentally left the windows open the whole afternoon. Lessons learned: it takes ~10 minutes to let out the majority of moisture. However it takes another hour to match the outside moisture level.

Reminder that if you are calling into North American time zone-anchored meetings from Europe, the meetings are an hour early this week. (Unusually only for one week this time.)

RFC/thinking out loud: Powering Portable Projects I want to power several 1m long #ws2812 RGB strips from power bank(s) for not a lot of money. The LED specs say 60 LEDs per meter and 60mA max power draw per LED. That's 3.6A/m (18W at 5V). Affordable USB-C […] [Original post on toot.kottman.xyz]

Yay! Guide for minimum downtime #postgres upgrades! https://stanislas.blog/2025/03/postgres-major-upgrade/

I've been trying a lot to use #freecad recently (v1.0.2), but it's crashing constantly for me, especially around mouse interactions. Latest one: /usr/include/c++/15.2.1/bits/stl_queue.h:359: void std::queue<_Tp, _Sequence>::pop() [with _Tp = SoMouseButtonEvent; _Sequence = std […]

Hurray! My 3d printer is running again after nozzle replacement and unblocking the feeder!
