Weeknotes 2026 W30: Spectacularly bad

July 20​–​26, 2026
 

Quick bits

  • Another heat wave? Fuck. Meanwhile, it hasn’t rained in London for a month. My experience of London so far does not align at all with the stereotypical image of a cold, windy, and rainy place. It’s been tropical, even.

  • I am recovering, slowly, from my cold/flu/COVID. I’m low on energy, and I’ve channelled most of that energy into just working. The coughing and sneezing have not fully disappeared yet.

    I tried going for a nice long walk, but was out of breath before even leaving the house. That long walk will have to wait.

    It’s a little strange that I’m finally living in London, and I’m not doing much — barely leaving the house, even. But I’m giving myself the time I need, and there is always tomorrow.

  • I still get occasional traumatic flashbacks from my time in Berlin. It will take me a long time to recover from the trouble I’ve experienced in Berlin.

  • Apparently, being able to put your foot on your head is considered being flexible. I can do that. I can even facepalm with my foot. Or should I say… facesole?

  • Mitchell Hashimoto’s Everyone Should Know SIMD made me curious about using SIMD in my TomatenMark implementation. Preliminary results show an overall improvement of about 400%. Not too shabby, though more experimentation is needed. I’m grateful for Zig making SIMD much easier; I cannot imagine doing the same work with C.

  • I bought a vacuum cleaner! It sucks hahaha.

Quick London bits

  • I don’t get how London has the reputation for being antisocial and unfriendly. Coming from Berlin, London feels chatty and smiley.

  • Apparently, taking parcels for your neighbours is not common in London. The Amazon delivery person was confused. The neighbour was confused. And when the parcel arrived, it was open, which I suppose didn’t help either in making me come across as a friendly neighbour. Perhaps London does expect me to be a little more… antisocial.

  • I’ve started looking for new places to live. My current abode doesn’t cut it, for reasons I’ve talked about before. And now that my nose is cleared up, I can clearly smell the mould in the bathroom.

  • Moving to a new place is financially tricky. I’m running low on cash. I’d have to put down a deposit without even having got back my Berlin deposit. I’d have to pay rent in two places for a while, too. And on top of that, the move itself — even if it’s just a man-with-a-van setup — will cost me, too. My next flat will have to be something where I can reasonably stay for a few years.

  • I had some viewings scheduled for the coming week, but most of them have already been cancelled. The rental market moves fast. I wasn’t able to do any viewings last-minute because of illness, but from now on, I think I’ll jump on every worthwhile viewing opportunity ASAP.

  • There is an early 2000s aesthetic that runs through so many properties in London. Metal rods and curved glass. It’s pervasive and I don’t like it.

  • My credit score has dropped to “poor.” It’s supposedly normal because I have a thin credit file. I’m considering getting a credit card and paying it off every month (I would have no issues with that) to build up a credit score. Is that worth the effort, though? Should I just let it run its course and let my credit score rise by not doing anything at all — minimum effort, maximum gain?

  • I still am not used to shops being open on Sundays. It’s unnatural! Der Sonntag soll ein Ruhetag sein!

Shower thoughts

  • “Emily” is short for “electronic mily.”

Bad automation

A bug in Linear made it connect newly opened GitHub pull requests to random Linear issues. The broken behind-the-scenes automation assigned me to random issues (even from the backlog of other teams) which then ended up being auto-closed. I pissed off some coworkers, and undoing the damage I indirectly and inadvertently caused took some effort.

But the real culprit is presumably an LLM that is spectacularly bad at its job.

What annoys me most about this, perhaps, is that the automation made the changes to these random issues of other teams in my name, with no indication that there was an automation involved. The log of changes made it look as if I deliberately chose to fuck with other teams.

I’m not against automation, but this went wrong on multiple fronts.

Creatively stuck

When it comes to creative work, I am perpetually indecisive about the medium that I want to work in. I started another game development project (putting aside the idea I was working on previously), one that’s much more focused on writing, and especially dialogue. But I also got it into my head that I could learn how to do pixel art. Like I don’t have enough to do yet. No wonder I keep burning out on hobby projects.

It’d be much easier if I could be satisfied with writing short stories or even flash fiction. I’d learn a lot by sitting down and getting it over with, improving steadily rather than trying to think about all the things that I am not doing instead. The perpetual desire to do other things leads me to not do anything. Highly suboptimal.

That said, I’m about to head out to a Shut Up & Write meetup, and my plan there is to continue the work on an interactive fiction game I’ve been prototyping. The social pressure will get me working on it without distractions for a while, and hopefully I’ll not loudly hear that good old constant question in the back of my head: “are you sure that you are using your time wisely?”
