Hmm… I'm becoming increasingly tempted to pull the plug on a potential 1.0 release any time soon. There's things I want the app to be able to do that don't fit within the current semi-flexible pipeline approach, and it would be painful to put out a release and have to maintain compatibility.

Hmm… I suppose I need to decide whether to release @pixel-processor.bsky.social in the macOS App Store. There's additional assets and prep required, and based on my inability to generate any interest, I suspect sales would be at or close to zero if you had to pay for it. Or indeed if it was free. 🤔

Doing more typings of late - trying to move towards a 1.0 release, although there’s still lots to do. It’s fair to say that it’ll always be a (very, very) niche app, but hopefully it’ll be useful to some

Next up is something long overdue - The Great UI Tidy-Up™ has finally begun. Although it’s mainly just putting things in boxes. 🤔
A screen from an in-development macOS showing a large image of a magic 8-ball sitting on a table, rendered as if it was on a late 80’s computer and TV.  To the right of the image are some user interface controls, but they’re not particularly relevant or indeed exciting.

The fate of Pixel Processor will soon become evident - I think it would take an awful lot of energy to get any kind of uptick in interest, and that’s something I sadly don’t have. Still, it’s not far away from being complete enough for the macOS App Store, even if that’s only in its current form.

Beta three brings news from afar, the headline being that video conversion is now supported. 🥳 You can now also use Pixel Processor on macOS 13 (Ventura) and up, rather than needing Sequoia. Join the TestFlight via pixelprocessor.co.uk

Retrospecs first appeared in the App Store twelve years ago today, which is a long time by anyone’s standards. There’s not been much in the way of new features recently, but I’ve been slowly working away on some bits and pieces. Here’s a sneak preview of what’s coming later this year.

Condemning riots isn't enough. We need policy action, including an immediate appraisal of X as a vehicle for coordinating far-right disorder. And we need political leadership, to challenge white nationalism as an idea, not to validate it daily and then complain when it turns violent.

I’ve been gradually working away on a re-write of the “engine” that generates the image conversions in Retrospecs, and that work is now largely complete. Whilst the original goal was purely to replicate the existing functionality, there’s also some new bits and pieces to play with. So that’s nice.
