Inklings: a tumblelog

While I’ve been setting up SPF records like this, it’s never occurred to me that domains with an appropriate SPF record might also need DMARC and DKIM records to go along with it. I’ll be setting that up.

The C64 Saver 2 is an open-source project intended to make overvoltage protection available and easy to make for anyone interested in using the old Commodore power brick together with the C64. The power brick is 20-30 years old and it is known for failure with overvoltage. This is caused sometimes because of broken solder joints on the regulator or the regulator itself failing.

I’ve pretty much always had an aftermarket brick for my C64, as the original died a few years after I got my original. I don’t think I should trust the almost three decade old replacement brick, so if I power up my C64 again, I’d like to build something like this to put in line between it and the brick.

Pikchr (pronounced “picture”) is a PIC-like markup language for diagrams in technical documentation. Pikchr is designed to be embedded in fenced code blocks of Markdown or similar mechanisms of other documentation markup languages.

The song really kicks off properly at around 1m in.

Testing in production is a superpower. It’s our inability to acknowledge it that’s the trouble.

I’m slightly surprised the A7000 is still supported!

I have an Acorn A7000 to fix. The CMOS battery has leaked horribly and, even if it hadn’t, it needs to be replaced.

That’s being played through a piezoelectric buzzer that’s being rapidly flipped on and off to do pulse width modulation. But that’s not the clever bit: the clever bit is how the different tracks are being mixed together.

I haven’t turned mine on in years, and the stories I’ve heard of it frying people’s machines gives me pause. This is meant to be a very good replacement though, and not too bad pricewise.

That bass line’s a chonky boi!

I don’t use Twitter anymore, aside from the odd semi-automated tweet, but if I were, I still wouldn’t trust them not to screw this up again.

I would like use my Spectrum Next to mess around with CP/M at some point, playing with some classic software from back then. I have a few things to figure out before that—which might end up in a blog post—but there are lot of interesting things in that archive.

I’d never heard of LBR archives before, but I hunted down a file format specification for it.

I already do most of these. I’ve yet to set up MTA-STS though, and there are a few other bits and pieces I could tighten up. Well worth a look, however, if you’re running your own mailserver.

For when people get too hyped up about things.

Looks like it might be useful to help do some bookmark cleanup as I clear out my backlog.

Hadn’t heard of pot (and minipot) before now. They look super interesting! It’s a jail management tool and can be pair with nomad using a driver.
