Blaugust Wrap-Up

2026-09-01 08:00:00

August is over, and that means Blaugust 2026 has ended. This was my first time participating, and I set myself the goal of writing 15 posts this month (the silver tier), which I'm happy to say I managed! Two of them ("tech sucks" and "I used to be excited about tech", links below) went kind of viral and made the rounds on Bubbles and Hacker News, which is always a bit scary. But I got a number of really nice and thoughtful responses, and the "tech sucks" posts also generated a number of blog posts in response, which I've linked at the bottom of that post.

Overall it was a nice challenge. I was surprised that I always managed to find topics to talk about without running out of ideas or writing about things that didn't really interest me just for the sake of getting a post out.

The only thing that's a bit of a shame is that I wasn't involved in the community too much because their platform of choice is Discord which I'm not a fan of, so I unfortunately missed that part. It was still great reading the posts from others that showed up in my feed, and there were so many participants that I couldn't possibly follow them all. I linked the posts that resonated with me in my weekly linkdumps.

A big thank you goes out to Krikket and the others for organizing! I'm looking forward to participating again next year.

For completeness' sake here's a list of all my posts from this month. Thanks everyone for reading and following and getting in touch with me!

My new old Micro Hi-Fi

2026-08-31 08:00:00

A couple of weeks ago I bought an old Walkman, because I felt like listening to some tapes again; something that I hadn't done in at least 25 years. This set me on a path to look a bit more into old Hi-Fi equipment. Not old as in from the 70s and 80s, but older than what we have today, which is essentially just Bluetooth or Wifi speakers and not much else (unless you want to go high end). Something that can still play tapes and CDs (I haven't owned a proper CD player in probably two decades, either), doesn't take up too much space, looks nice and isn't too expensive. And so I bought this.

The JVC UX-P3R in my living room

This is the JVC UX-P3R from 2001. I wish I could find the original product page from the JVC homepage from back then, but I've had no luck. It seems to be gone forever.

I bought this because I like the early 2000s design, it has a CD player and a tape deck, and it's small and light. Exactly what I was looking for.

I got it from eBay for 27 Euros including shipping, and it was described as fully tested and working. Which turned out to be a very optimistic description of the actual condition.

The belt in the tape drive had disintegrated, but that was something I had expected from a 25 year old drive and I was pretty sure that the seller hadn't tested this, because who still plays tapes these days. You know, apart from some weird people who also still write blogs... What I didn't expect though was what I saw after I opened the device. First, it was incredibly dusty. But then there was this:

A crack in the board

There was a huge crack in the board near the speaker terminals. I'm going to go out on a limb here and say that this device was maybe not very thoroughly tested, because that should have been noticed. Though to be fair, this could have also happened in transit. The remote was also missing, even though it was included in the eBay auction.

The seller was very nice though when I got in touch with him. He gave me a 50% discount on the price, and he also sent me the remote in the post. Which turned out to be just as dirty, full of crusty battery acid from a leaked battery, and before handing it over the postman charged me three Euros because the guy had bought the wrong postage stamp... the usual eBay madness.

The stereo cleaned up well though, and after a disassembly and a good clean the remote worked, too, and had not taken any damage from the leaked battery. I put a new belt into the tape drive and stabilized the crack in the board with some super glue and patched the broken solder traces with wires and a few solder bridges. Thankfully the crack was in the corner and there were just a handful of broken traces, so that was an easy fix.

The crack in the board fixed

My biggest worry was that the CD player would refuse to play any CDs, because that's hard to fix if it can be fixed at all, but it turned out to be working fine.

Overall, after cleaning and repairing it, the stereo turned out really nice. It didn't come with any speakers, which is fine because I already have a good pair of living room speakers which I could connect it to. It was also really easy to open and take apart and get to all the components. Techmoan recently made a video in which he tried to repair a Sony micro Hi-Fi from the same era, which turned out to be a complete disaster. But this one was well put together and great to work on. I don't know if this is true for all JVC devices, but it is for this.

One thing I want to mention if you're thinking about buying some vintage (or just older) Hi-Fi gear: Do some research before you buy and check if you can find not only the user manual available online, but also the service manual. For this device I found both, and the service manual is really detailed and comprehensive and was really helpful for the repair. It contains parts lists, schematics, block diagrams, board layouts and even diagrams about what the output of the CD player's laser unit should look like on an oscilloscope. So when the CD player inevitably fails at some point (hopefully not soon), I can go in and see what's wrong and maybe even adjust some things to get it working again.

And now, with the stereo fully working, I can finally do what someone on Mastodon suggested in a response to my Walkman post: Record some mixtapes to listen to on the go.

an animated 90s style GIF that has the word Links in green font on black background

Last week I posted a link to a news aggregator website, which collects links to all different kinds of news articles and blog posts. It was brought to my attention that one of the links on this site pointed to a post titled "Stop Making TUIs", which advocates for abandoning text-based user interfaces in favour of vibe-coded GUIs.
Needless to say, I am deeply horrified by this inexcusable oversight of mine, and I owe a massive apology to anybody who was rightfully offended by me linking to a site linking to such obscene content. In no way do the ideas expressed in this article represent my own views, and I want to make it very clear that I fully understand the impact of what I've done here and how wrong it was. I make no excuses for this type of carelessness and I take full responsibility for the consequences of my actions. Most of all I want to apologise to everyone using text-based interfaces to do their daily work. I understand how hurtful this has been to you and I need to take accountability for my actions. The only way for me to regain your trust is through action, and I promise to choose my links more carefully in the future. I know better now, and you have my word that this kind of thing will never, ever happen again. 1

5 Albums

2026-08-26 08:00:00

A few weeks ago, Noisy Deadlines posted a list of 5 albums that shaped her taste in music. I was going to write a post like this too, but it completely slipped my mind. Today she published another post about 5 books that shaped her, which reminded me of the 5 albums. So here's my list, these are 5 albums that had a huge influence on me.

AC/DC - Highway to Hell (1979)

This one I'm pretty sure is the first "heavy" album I bought. Before this I listened to mostly pop music from the 60s, 70s and 80s, or stuff that was on the radio. Then in my late teens I discovered this album and it was my gateway drug into the world of Hard Rock and Heavy Metal, music generes I still love and listen to to this day. I already wrote a review of this album (and all other AC/DC albums), so I'm not going to repeat myself here too much. It's a fantastic album and I love it.

Judas Priest - Priest...Live! (1987)

This album, particularly the live video version of it, shows Priest at their absolute peak. Halford had quit drinking and smoking and his voice was at it's absolute best during this era. Tipton and Downing's dual guitar attack is legendary, and just look at the clothes and the hair! It's peak 80s Priest. They're one of my favourite bands ever, and this album was on heavy rotation for a long time after I discovered it.

Candlemass - Epicus Doomicus Metallicus (1986)

This one is a masterpiece. Candlemass is a Swedish Doom Metal band which plays music very much inspired by 70s Black Sabbath, with heavy riffs and dark lyrics, but more melodic and operatic vocals than what Sabbath did at the time. This is their debut album, and they were only in their early 20s when they recorded this, which makes it even more impressive that it's so good. If you look up any list of "The X best Heavy Metal Albums of All Time", this album is almost always included, and usually at least in the top 20. And for good reason, because it's just perfect. I listened to it countless times and I know pretty much every lyric, guitar part and drum fill by heart. I even know where all the little mistakes are, of which there are a few because they recorded on a tight budget. And I even have the album cover tattooed on my arm. That's how much I love this album.

Black Sabbath - Paranoid (1970)

Any number of the old Black Sabbath albums could be in this spot, but this one has Paranoid on it, and Paranoid is amazing. Full review is here in my Black Sabbath post. I play electric guitar and Tony Iommi's riffs are a huge influence on my; so much so that I own his signature Epiphone SG guitar which I've had for I guess 15 years or so, and I played it every single time I've played live with my band. And it's still my main guitar that I play almost every day.

Uriah Heep - The Best of... (1975)

Again, I could put any number of the old Uriah Heep albums from the 70s here, but I think the first one I heard was the Best of, the European edition which was released in 1975. Lady in Black is on there, which is incredible and I've loved this song ever since I first heard it as a child. It's just so good. What I love about Uriah Heep is the blend of Hard Rock music and operatic vocals with intricate multi part harmonies. This was later picked up and refined by many other bands, most notably of course Queen. They perfected it, but Uriah Heep came before and their music was hugely influential for me when I was young. I've also seen them live numerous times and they are still a force to be reckoned with.


And there we go. I could add another 10, but these are the first that came to mind; and of course it's not just these particular albums but the bands in general that had a huge influence on me. I've seen all of them live at least once; some have since retired and/or lost key members, others are still out on the road and I hope to catch them again when I have the chance.

How I use AI

2026-08-25 08:00:00

I linked this article by JA Westenberg in my last linkdump, and in it she mentions that she has a "How I AI" section on the about page of her blog. A different post I read this week talks about the authenticity of digital art in an age where everybody can just slop generate everything with a few prompts. And then there's this line I read somewhere, I forgot where: "If you can't be bothered to write it, I can't be bothered to read it". And so I thought I'd put together my thoughts on AI usage on this site.

Plain and simple, this is a blog written by a human for humans. This means that everything you read here has been written by me (with a few exceptions in the past that I'm not going to repeat going forward 1).

I don't use AI to generate ideas, I don't use AI to write posts or generate images or write code.

I use a few tools though, and some might be or are AI powered:

  • Spell check and grammar check. I write in Obsidian and use the integrated spell checker and recently started using Harper as a grammar checker. I don't think that's AI powered, but I'm not 100% sure. In any case it just makes suggestions, but doesn't write for me.
  • I'm not a native English speaker, so if a sentence just doesn't feel right to me and I can't get it to sound right, I might put it into an AI writing assistant to see how it reformulates that sentence. This happens maybe once every handful of posts. In that case the ideas and words are still mine, but AI helped to make it more readable.
  • I don't use AI to generate code, but I sometimes use it instead of using a search engine for looking something up. For example, if I don't remember how to split a string at a particular delimiter in python, instead of putting that into google a search engine that isn't horrible and reading through Substack posts, I might also put it into AI as a prompt ("How to split a string in python by a delimiter") and use this as a lazy way to get the answer instead of searching through the python docs. I have had the experience though that this can give me subtly wrong answers, so on a number of occasions I've also given up on this approach and just did what I should have done from the start - read the docs. (I use duck.ai, because I don't know anything else and that at least promises some privacy protection)

And that's it. So in short, this blog is written by me and what you see and read here comes out of my own brain. When I use AI, I use it the same way I would "use" a person sitting next to me - to ask it a question when I'm stuck and see if it can help me out. I think that's an acceptable way to use it.

I used AI to generate parts of the text in these two posts, and I also experimented with automatically translating my posts from German to English, but abandoned the idea pretty quickly after almost everyone told me that they prefer my imperfect English over the automatic translation.

an animated 90s style GIF that has the word Links in green font on black background

We had a solar eclipse here in Europe last week. I didn't see it this time, but I've seen I think two partial eclipses before and they were always fascinating to witness. We had a total solar eclipse that was visible in South Germany where I live back in 1999. I remember watching this from the roof of my school with a couple of friends and teachers. We saw the eclipse begin and the moon move in front of the sun, and everybody was hyped up and excited - but about half an hour before totality clouds started moving in, and by the time it got dark the sky was completely overcast and we couldn't see anything. It was incredibly disappointing. Still fascinating to see it get dark and then light again in the middle of the day, but man… a once-in-a-lifetime opportunity ruined by clouds. Actually, maybe twice in a lifetime, because the next total eclipse will be visible here in 2081, when I will be 99 years old. Make sure you get subscribed so you don't miss my review of it!
