I have set up a fundraiser for the SequenceME genetic research project into #MECFS and #LongCovid. I'd be hugely grateful for contributions and shares.

My retro CPU app is now out. Lots of information on your favourite 8-bit and 16-bit processors. It’s all free too - so give it a look! Instruction sets, pin-outs, sample code and more!

Sure it costs thousands of dollars per developer each month but at least you’re getting software that you don’t understand how it works with dubious legality for it.

Once again, Pi Day rolls around, and once again I forget to actually do anything substantial to promote PCalc.

Even worse, I added Tau in the latest releases, and the Pi people and the Tau people have been at war for decades. Don't ask…

But the current iOS version is 3.14.x and so Pi wins for today!
