    An interesting idea. Gave it a try and it seems to work. There’s more info about it on the Github repo.

  • Just placed the exit on Level 3-2 on my Godot game. The level still needs prettying up but the critical path is now done. I’ll think this will be the last level I build. There’s still so much work to do: polishing, backdrops, menus, etc. But no more content. Kind of want to put a pin in this one.

  • 🔗 Simon Willison: How Rob Pike got spammed with an AI slop “act of kindness”

    Rob Pike (that Rob Pike) is furious […] Rob got a 100% AI-generated email credited to “Claude Opus 4.5 AI Village” thanking him for his contributions to computing. He did not appreciate the gesture.

    Got a lot of emotional swings while reading this: outrage that someone would use AI agents to send spam like this, understanding as to what actually happened, then distaste with those responsible in their belief that the time wasted receiving emails like this is an acceptable external cost.

    But really, the whole experiment seems irresponsible. I can understand the want to see what these models could do, but come on: don’t given them access to a computer open to the Internet without any supervision. Rob Pike, a notable computer scientist that would be known to all these models, is right to be outraged. I would be too if I received this sort of unsolicited slop.

  • 🔗 Weird Medieval Guys: How birds got human names

    Magpies were originally known simply as “pies” until the nickname “Mag”, short for Maggie, short for Margaret was added to the front sometime in the Middle Ages. Before it began to be treated as a single word, it was rendered as “Mag Pie”, a sort of fanciful full name for the creature.

    Fascinating. This is, shall we say, the “money” quote of the linked post, but the rest is still quite an interesting read.

  • 2025 Song of the Year

    Once again, a need to play something during Christmas Eve Mass has come around, so it’s time to elect 2025’s Song of the Year. No obvious song stood out this year, unlike 2023 and 2024. Looking back on what new music I listened to, it was mainly a lot of Enya and Lee Rosevere, with a bit of Anders Enger Jensen. Near the end of the year I also started listening to Jon Hopkins, in addition to one or two other artists featured in the “medleys” published on Music For Programming. Continue reading →

  • TIL that you can make a call to someone, put them on hold, then start a second call to that same person, and the POTS network supports this without any issues. You can even merge the two calls, resulting in two active calls to the one recipient.

  • The place I’m staying in has a drip-coffee machine. Normally I shun such contraptions (I’m a Melburnian with Italian herritage, damnit!) but ultimately, I don’t mind using them. In fact, I prefer them over the pod-coffee machines: the coffee is better and there’s less waste.

  • In my last post I mentioned that I heard AI music in the past. I’ve tried a service to generate this music a couple of times, but I’ve never really liked what it produced. It all sounds vapid. It’s got the surface criteria of a music: it’s chromatically correct, there what appears to be build up of tension. Yet, it all sounds like fluff to my ears.

    My theory is that good music needs to have repetative elements, but enough variation to avoid it sounding boring. It could be variations to one or more theme; could be lyrics (chorus as verses); could also be the orchestration, where instructions come and go. AI music has none of this: none of the music has a central theme one can use as a hook, nor is there any variation to the instrumentation. I’ve only tried generating instrumentation songs so maybe music with lyrics sound better. But nah, not for me.

  • Current day renditions of classic and modern Christmas songs are really bad. I don’t know what compels artists, which I assume are contemporary, to release this rubbish. Honestly, I’d rather listen to AI generated music, and I’ve heard AI generated music.

  • Found another 20 cent coin from Singapore in my washing the other day. I now think they did come from my 2023 trip to Singapore, as I checked my cash box to see if it was the same coin as last time and I found a $1 SGD coin in there too.

    Three Singapore coins are placed in a row on a textured surface, with one $1 coin from 2012 and two 20 cent coins.

  • I just got an email to view my LinkedIn Year In Review.

    Why is that a thing....No one wants that.

    Greg Morris https://mastodon.social/@greg_morris/115735615183681546

    Got curious and took a look at my LinkedIn “Year In Review”. Well okay, I opened it. But when I found out it featured an animated slide show (is this how Instagram Stories work?) that I couldn’t quickly swipe through, I closed it again. Didn’t help that the first slide was “you joined LinkedIn in 2011”.
