Just watched an old episode of #ufo after a long time. Can we just stop for a second to admire this kick-ass intro? Those fast cuts and the music. Just wow. I had to rewind it a couple of times just to watch the intro again. https://youtu.be/YPhDvaZ7GUc #scifi #GerryAnderson #tv #nostalgia

@vga256 As a former long time user of Google Workspace to remind others that such services are replaceable. 😜 Sorry for trolling.

I created this cable organizer in #FreeCAD some time ago. It's a modular design of stackable boxes with variable widths. Wrote a FreeCAD macro, which makes the process incredibly efficient to export many widths and styles to STL with a single click. Even the […] [Original post on oldbytes.space]

I am playing TIS-100 by Zachtronics on #linux right now. It's a game where you need to program parallel nodes with low level assembly in order to solve different puzzles. Very cool. https://www.zachtronics.com/tis-100/ #games #indiegame #coding

This week, I created this dispenser for AA and AAA batteries in #freecad. The FreeCAD file and STL can be found on Printables. https://www.printables.com/model/1676944-ultimate-dual-aa-aaa-battery-dispenser #freecadfriday #diy #3dprinting #cad

I encountered this CAPTCHA today. Boy, did I have a hard time solving it. Maybe I am a machine?

Well, I just asked #claude where I can download it's source code. It denies everything. 🤣 But the wayback machine had me covered. https://web.archive.org/web/20260331152215/https://pub-aea8527898604c1bbb12468b1581d95e.r2.dev/src.zip

#freecad 1.1 is out. Those new features are awesome 😍. https://www.youtube.com/watch?v=bYdobpjTypg

Just watched #startrek #starfleetacademy episode 8: The Life of the Stars. What a pile of 💩. Real cringe. And the worst Star Trek character of all time is back.

I run a small business and over the last couple of months, I’ve been working hard on reducing my dependencies on U.S. providers and #techbros. Latest step: Email and docs are no longer on #GoogleWorkspace. I’ve moved everything to #mailboxorg and #Nextcloud […] [Original post on oldbytes.space]

It was bothering me that the date format on my #Fedora / #KDE system was kind of wrong. I am Austrian, and we are used to dd.mm.yyyy. But on my system it was always displayed as dd.mm.yy (two‑digit year instead of four). I thought surely it could be […] [Original post on oldbytes.space]

Doing #adventofcode again. Working my way through 2020 and playing with numbers again.

Printed an E10 light bulb socket designed in #freecad. Files are on #printables: https://www.printables.com/model/1548066-e10-socket-for-mini-light-bulb #3dprinting #freecadfriday

Mapping out which USB ports are in which IOMMU group of my motherboard and can be safely used for PCI passthrough to a VM running on #proxmox. #linux

I completed #AdventOfCode 2021 today by finishing day 25. I did it in #TypeScript, which was ok, but it’s missing some important features I’m used to, such as object equality and comparison mechanisms. The same goes for tuples, which can’t be compared by value […] [Original post on oldbytes.space]

Doing #adventofcode 2021 day 24 the easy way. Wrote C++ code that uses all cores to look for the solution while I think of a better way. Let's see who will get the solution first, my brain or the program.

Didn't I say I am glad, that #adventofcode was shorter this year? Look at me doing AoC 2021 now. 🫣 https://github.com/nharrer/AdventOfCode/blob/main/2021/day19/solve-day19.ts

I’ve been a long time #Windows user (since 3.11). And I also use #Linux a lot for server stuff. But my working machine has always been windows. But this year is the year. About a month ago, I completely switched to Linux, and I went all in. I’m now running a […] [Original post on oldbytes.space]

My current machine is an AM4‑based Ryzen 5 3600 with 32GB of RAM that I built in 2019. I’m running #proxmox, where one VM with PCI passthrough is my main/daily work horse. Works like a dream. I planned on getting myself a new machine around this time, but with those RAM prices, no thanks. Grrr […]

Also, a shoutout and high‑five to a few fellow Mastodons who posted incredible stuff, interacted with me, or are just plain awesome: @jochie @movq @alrj @tipiak75 @RogerBW @jeff @everythingalsocan @psf @papajohn @sol_hsa @mina @Tipa @psychotimmy @teotwaki @mnvr Thanks, #adventofcode was just […]

Some thoughts about #adventofcode 2025: So that's it, folks, for this year. It has been huge fun again. As usual, I'm sad that it's over, but also a bit glad it was shorter. It can be quite a burden with family, kids, work, the Christmas season, and AoC on top of it. Altogether, I feel good […]

#AdventOfCode Day 12: Christmas Tree Farm Sigh. I wasted the whole morning rotating patterns, throwing away identical patterns, pattern matching, and stuff. Then, on a hunch, I just entered the number of rows that could be solvable (eliminating those where […] [Original post on oldbytes.space]

#AdventOfCode Day 11: Reactor Wow, turned out to be the almost shortest and fastest code of this year. Enduring so many past AoC graph puzzles has finally paid off. I even finished both parts before breakfast. Okay, I’ll stop bragging now. There is still one […] [Original post on oldbytes.space]

#AdventOfCode Day 10: Factory Part 1 was easy, and I did it before breakfast. But Part 2: Oh my! I tried to do it with combinatorics first, and it was too slow, even after countless optimizations. There is probably a dynamic programming way to do it, but […] [Original post on oldbytes.space]

#AdventOfCode Day 09: Movie Theater Oh boy, did I get lost on part 2 by trying to solve it through fragmenting the area into rectangles. While it was getting more and more complicated, it occurred to me that I could just compress the input and brute force it […] [Original post on oldbytes.space]

A tip for people doing #adventofcode in #csharp: use a checked block, or better yet, add true to your .csproj. Otherwise, overflow errors will not be thrown. A classic AoC trap, when the example input works but the real input doesn’t.

#AdventOfCode Day 08: Playground Another fun puzzle. I was afraid that building all the pairs would be too slow, but actually 1000*999/2 is not very much, and the code completes in a quarter of a second, so good enough. Today I refrained from structuring […] [Original post on oldbytes.space]

#AdventOfCode Day 07: Laboratories What a cool puzzle! I love that the solution represents a beautiful Christmas tree. On the second part, I first thought about recursions. But then, wait a second... It's way easier. On a side note: I switched from Windows […] [Original post on oldbytes.space]

#AdventOfCode Day 06: Trash Compactor I first solved the puzzle it with a couple of loops. Even though functional code is ugly in C#, I took my time today to unroll all the loops into a functional style, which makes the code pretty compact. With 20 lines […] [Original post on oldbytes.space]

#AdventOfCode Day 05: Cafeteria Alrighty. Today was about has hard (or easy) as yesterday for me I'd say. But I am not complaining. The hard stuff is coming soon enough! With 21 lines of code, this has been my smallest solution so far this year. #CSharp […] [Original post on oldbytes.space]

#AdventOfCode Day 04: Printing Department Today was good. I was done in about 10-15 minutes, which is phenomenal for me because I am a rather slow person. I spent some time improving the code and noticed that the functional methods like .Count and .Sum are […] [Original post on oldbytes.space]

It's amazing how many people are tooting about #adventofcode on #mastodon this year. I remember that 2–3 years ago, it was only a handful of regular people. I almost felt lonely here. Last year, I was at least able to look through all the toots of the day with the #AdventOfCode hashtag every […]

#AdventOfCode Day 03: Lobby Today was right up my alley. I think that is the kind of problem that really occurs in a developer’s everyday work When I was done, I also tried to do it in a more functional way, but it looked so complicated. In the end, two […] [Original post on oldbytes.space]

#adventofcode Day 02: Secret Entrance It took me a bit longer than yesterday, but this time both answers were correct on the first try. Nice! #csharp code is here: https://github.com/nharrer/AdventOfCode/blob/main/dotnet/2025/Day02/Day02.cs Puzzle: https://adventofcode.com/2025/day/2

#AdventOfCode Day 01: Secret Entrance Oh man, I really fumbled my way through part 2. It sounded easier than it actually was. I kept yelling to myself: "Hey it's day 1, you should be finished by now!". #CSharp code is here […] [Original post on oldbytes.space]

I almost forgot about #AdventOfCode this year. Well, It's on tomorrow! Last year I did it in #Rust just to learn the language, but I haven’t used Rust since, so I’m feeling very rusty 🫤. Since I probably won’t have much time this year, I think I’ll pick […] [Original post on oldbytes.space]

Thin sheets of printed TPU almost behave like leather. I repaired my son's lunch box after a lid broke off. It's not the prettiest fix, but my son likes it for some reason. It does have a bit of a steampunk vibe. I tried to glue it on, but neither CA glue nor […] [Original post on oldbytes.space]

I absolutely love #opensource software. I use #OctoPrint with Octolapse to create time-lapses of my 3D prints. However, sometimes I want to decide whether to print with or without a time-lapse right when I start printing a piece, as having time lapses enabled […] [Original post on oldbytes.space]

Printing silly stuff for the kids. #3dprinting

I upgraded three servers to #debian Trixie yesterday. As usual, it went smoothly. However, one #docker container running Nagios showed significant performance issues after the upgrade, with the CPU stuck at 100%. Updating the Docker image to the latest version did not help either. #linux #docker

Sehr cool und nostalgisch. Das ASM gehörte zu meiner Kindheit. Genau so wie PowerPlay, 64er und Happy Computer. Habe eben die aktuelle Ausgabe #9 der Neuauflage bekommen. #retrogaming #retrocomputing #retro

I had this unusual box to print, which would always have an overhang, no matter which direction you printed it. The good old print at a 45° angle trick worked like a charm. Of course, it was designed in #FreeCAD. This was the first time I used the Thickness […] [Original post on oldbytes.space]

Earlier this week, a guy from sales (no kidding!) came in very proud, telling us he doesn't need us developer guys anymore. It was a really really simple thing: he set up a PHP page that displayed some sales data read from an Excel sheet, all vibe coded. Setting aside his questionable choice of […]

Got myself this gorgeous #mechanicalkeyboard last week. It's an #Evo80 with linear switches. Typing almost sounds like raindrops. I love it!! I've been typing for over 40 years on all kinds of keyboards now, but I never actually learned to type properly. I […] [Original post on oldbytes.space]

I created a ramp for my robot vacuum to overcome a big step between rooms. While many ramp models already exist, I needed one which is higher on the left side than the right. So I designed a parametric #FreeCAD model where you can set the length, width, and […] [Original post on oldbytes.space]

Fixed my wife’s umbrella handle with #FreeCAD. Usually, I just use a thread from the Fastener workbench, but this one wasn’t a standard at all. Cutting it out with the Subtractive Helix tool was so easy that I might just use that method all the time from now […] [Original post on oldbytes.space]

Does anyone have a suggestion for a good alternative to #Postman? I never liked it much, but got used to it because a team I was part of used it heavily. It's a prime example of #enshittification. I’ve also used Talend API Tester, which isn’t bad. However […] [Original post on oldbytes.space]

Replaced the battery in my #car. Gee, it used to be so simple: Old battery out, new battery in. But nooo. In modern cars, you're supposed to keep the voltage present at all times so all kinds of stored sensor values stay intact. I did that using a power supply […] [Original post on oldbytes.space]

My keyboard has an USB port on it's right side. That is just the perfect spot for a fingerprint sensor. No more passwords for logins. Nice.
