Installed the latest version of Android today. One obvious change: the calculator app displays fractions in the result. And there’s no way to turn it off.

This… doesn’t appeal to me. Not enough for me to change apps, at least not yet. But I wish there was a setting to change it back to decimals.

Spent some time today building a site for my Go utility packages. A feature I’ve decided to add is a Go template playground, where you can test out Go templates in the browser. Not something I’ll use everyday but I’ve occasionally wished for something like this before. Could be useful.

Project update for Mainboard Madness. Well, today’s the deadline for getting the thing code complete, and what a surprised, it’s not finished.

To be fair, it’s pretty close. All the levels are more or less done, and the beats of the in-game lore have been added. It all just needs tightening up a little. I spent today working on the end-game phase, which mainly involved coding up the credit sequence, and making sure I include credits for those involved in the original game (and who’s artwork I lifted).

The work remaining is to finish one or two game elements, adding a proper app icon, and finishing off the website. I’m wondering whether to add sound, but I feel bad enough taking the artwork from the original game, I rather not take the sound effects as well. That will mean the game will remain silent for the time being, but I can probably live with that for now.

I think we’re still on track for getting this finished by this time next week. Last dash to the finish line, then I can put this 9 year project to rest for a while.

Working on my Chips Challenge “fan game” this morning. Added the notion of “lower thirds,” which will show text at the bottom of the play field. I’m hoping to use it for narrative or way-finding, like here in this hub level:

Also working on puzzle design. There’s about 19 or so “real” puzzles but I’m wondering if it’s worth adding a few tutorial ones for those that have never played the original Chip Challenge before. I’ve done about 5 such puzzles and I think I need to add maybe 3 or 4 more to cover everything I’m hoping to demonstrate. I wish I liked puzzle design more than I like tinkering on the engine.

Of course, the big question is why I’m working on this at all. There is, for lack of a better word, a vision for this, in terms of narrative and structure, but this project has been in development on and off for about 9 years or so, and I’m wondering if it’s time to just stop working on it altogether. I really am starting to get sick of it, in a way. And yet, this project has shown remarkable staying power over that time that I feel like if I don’t actually wrap it up, it’ll just continued to be worked on. It feels like the only way to end this project is to finish it, in one way or another.

So I’ll set myself a dead-line: something releasable in two weeks, and actually released a week after that. After that, no more! I’ll work on something else.

Attempting to design an app icon for a Chips Challenge fan game I’m working on. Going for something that looks like the fireball sprite in the original game with a hint more realism and tinted in the colour blue. For reference, here’s the original fireball sprite:

And here’s my attempt:

I started with Stable Diffusion to get the base image:

Then imported into Acorn to rotate it, colourise it, and distort it to look a bit closer to the original sprite.

Desaturating the original image got rid of the purple centre, then applying the Glowhoo and Hue Adjust effect recolourised it to the blue I was looking for (I’m not sure what the Glowhoo effect does, but it seems to adjust the colour based on the pixel intensity, so it was good enough for what I wanted). Finally, I added a Twirl Distortion effect to achieve the slight warp in the star.

And yeah, it’s not going to win any design awards, but it’s good enough for now.

Oh, and just for kicks, here was my first attempt of producing the sprite using Affinity Designer.

That’s definitely not going to win any design awards. 😂

I’ve been working on Micropub Checkins over the last week. It’s been a bit of a rush trying to get it into a usable state for an upcoming trip. And by “usable”, I mean a form that I can tolerate, and when it comes to projects like this, I can tolerate quite a lot. It can have a really dodgy UI (which this does) and miss some really important features that are annoying to work around; but if it works, and doesn’t loose data, I’ll be fine with it.

The last week was dedicated to making the act of checking in distinct from publishing it. Until now, check-ins were published the minute they were entered, meaning that you cannot check-in somewhere unless you’re comfortable with people knowing where you are the minute you do. Yes, some people like it that way, but not me. And I’m aware that this’ll only be the case if people are following my check-in blog, which I’m doubtful of.

So pressing the floating action button and choosing a check-in type now starts the flow of a new check-in that will get saved in an SQLite database. You can edit the check-in whenever you like, so long as it’s not published. Currently there’s no real way of deleting a check-in unless it’s been published. This is a bit dodgy, but it’s a good example of how tolerant I am with working around these feature gaps for the moment.

Check-ins can be published by tapping the upward facing button on the main screen. Any check-in with a lock is private and will not be published until you toggle the “Ready to publish” switch in the properties. Doing so will not change the date of the check-in: it will still have the date and time that check-in was created.

On the subject of publishing, I had some issues with Dart’s date and time methods. The method on the DateTime class used to produce an ISO-8501 date-stamp don’t include the time-zone if the date and time is not in UTC. This is important as I want the post date and time to be as close to the check-in time as possible, and in the time-zone of the phone. DateTime knows all this, including what the time-zone we’re in. So why didn’t the developers include it in the ISO-8501 date-time string?

This is really strange. Fortunately, ChatGPT stepped in to help out, writing a function which will add the time-zone offset to the ISO-8501 date-time string:

String formatTimeZoneOffset(Duration offset) {
  String sign = offset.isNegative ? '-' : '+';
  int hours = offset.inHours.abs();
  int minutes = (offset.inMinutes.abs() % 60);

  return '$sign${_padZero(hours)}:${_padZero(minutes)}';
}

Honestly, ChatGPT has been so helpful over the past week with this project, I probably should give it a credit if I get this polished enough to release.

I got a little bored today so I added task progress indicators to this Obsidian roadmap thing I built for work.

When a task is created, but is not yet scheduled, it appears as an outlined rectangle. It turns into a grey rectangle when it’s added to the sprint. It then changes colour as the task progresses through the software lifecycle; turning purple while it’s being developed, blue while it’s being tested, and finally green when it’s ready for release.

They’re implemented as embedded SVG images, added directly to the note much like the span element used for status labels.

It’s nice being able to add embellishments like this. Obsidian treating notes as regular files on the file-system is a huge advantage for these sorts of automations. No need to learn how to make a plugin; just write a shell script¹ that’ll output Markdown, schedule it to run a couple of times a day, and you’re good to go.

Back working on Micropub Checkin. Re-engineered the home page to now include a list of what would eventually be check-ins — both historical and soon to be published — complete with the check-in type emoji as the icon:

The same list of emoji icons now adorn the check-in type picker as well (except for the airplane one which seems to always be shown as what I can only describe as the “Wingding” representation):

I went around a bit trying to work out how best to use these emojis icons in the leading slot of the ListTile widget. I expored trying to convert them to IconData, but it turns out just using a Text widget with a large font worked well. I wrapped in in a Widget type with a fixed font-size and so far it looks quite good, at least in the emulator:

class EmojiIcon extends StatelessWidget {
  final String emoji;

  const EmojiIcon({super.key, required this.emoji});

  Widget build(BuildContext context) {
    return Text(emoji, style: TextStyle(fontSize: 26.0));
  }
}

Also started working on a Cubit to handle state for the main page. I had a bit of trouble working ont where the soon-to-be database call to get the list of checkins should go in the cubit. After asking ChatGPT, it looks like the initializer is the best place for it:

class CheckinListCubit extends Cubit<CheckinListState> {

  CheckinListCubit(): super(LoadingCheckinListState()) {
    loadCheckinList();
  }

  void loadCheckinList() async {
    var listOfCheckins = await read_database(); 
    emit(FoundCheckinListState(checkins));
  }
}

I’ve got some scaffolding code in place to simulate this, and so far it seems to work.

I need to start working on the database layer and having the ability to edit and delete check-ins before they’re published. I think I’ll tackle that next.

Remember in Gödel, Escher, Bach when they were saying that a (then) theoretical AI is less like a calculator and more akin to the human mind; and just like the human mind is likely to produce errors in the answers it gives? Well…

For reference, macOS Ventura is the current latest release.

Update: Turn’s out the reason for this is that ChatGTP’s data-set only goes back to Nov 2021. See follow-up post.

Here’s a bit of a blast from the past. I managed to get ccedit working again. This was the original level editor for workingset.net/2022/12/2… my Chips Challenge “fan game” I’ve been working on.

I’ve been designing a few levels for it recently, but since moving to a new Mac, the level editor I was using was going to be difficult to port. It’s QT application and the QT bindings were a pain to setup, and I rather not go through that again. I was using a Mac at the time I started working on it, but I wasn’t yet ready to go all in on MacOS. So to hedge my bets, I decided to go with QT as the UI toolkit.

This was 5 years ago and I’m unlikely to go back to Linux, so choosing QT was a bit of a bad decision. I think if I had my time again, I’d go with something like AppKit.

Anyway, the level editor still works but I have to log into a screen share to use it. I’d like to be able to edit levels on the machine I’m using now.

The code for the original level editor was still around but it hasn’t been touched in ages. It’s basically an SDL application — the same graphics library I’m using for the actual game itself — and the SDL v2 bindings I’m using are still maintained, so updating those were quite easy¹.

One thing I did have to pull out was the Lua VM². The editor was using old C Lua bindings. Better Lua VMs written in pure Go are now available, so I didn’t want to keep using these old bindings anymore. In fact, I didn’t want to use Lua at all. Lua was originally used for the level scripts, but I replaced this in favour of another language (which is no longer maintained 😒, but I’m not changing it again).

So far the editor boots up, but that’s about it. I can move the cursor around but I can’t add new tiles or load existing levels. There seems to be some weird things going on with the image name lookup. I originally thought image name were case insensitive, but after looking at the image name lookup logic in the game itself, I’m not so sure.

How much time I’d like to spend on this is still a bit of a question. It all depends whether I’d like to release the game itself in some fashion. There are still questions about whether I’m allowed to, given that the graphics are not my own. Still need to think about that.

But in any case, good to see the old editor again.
