Google Season of Docs

I only saw the suggestion from Bergi just now, so this is a placeholder. He’s a fine coder with loads of experience, I’ve done lots of docs. I strongly think the rdf-ext work is worthwhile.

Not Climbing : Washing Machine Belay

I’ve not had a functioning washing machine for several years. Not a major inconvenience. I’ve always been lazy about washing clothes, nowadays can justify for green reasons. As long as I have a clean shirt if I’m going out anywhere, that much is hand-washable. Girlfriend Mari has kindly been doing bits for me for the past couple of years. But...

Not Climbing : Shiny Things

Do you remember when you first saw an LED? Ok, I don’t remember seeing any LED for the first time, it would have been in a watch or calculator in the 1970s, slightly obscured by a screen that cut it’s brilliance. But I do remember seeing the component on it’s own for the first time when I was about 14,...

Create your own Synths/VSTs in Windows

tl;dr – get the demo of SynthEdit This is historical as far as I’m concerned, I’ve avoided MS software like the plague for a very long time now. But this was a case in a closed-source environment where things worked very well for me. Was about 10 years ago, so YMMV, but I’ve no reason to think it’s not still...

Clarinet Craziness

Mouthpiece Let me get this out of the way first: a few days ago, I was chatting with me owd Furniture College mate Jim, he’d noted my bright red clarinet. Knowing his keyboards, he remarked that they were probably a good fit alongside synths. I responded, yeah, and that I thought clarinets produced (something you could approximate with) a sawtooth...

Certbot Renew Pain

Something’s been driving me mad the last few days… tl;dr : certbot certonly -vvv –debug-challenges –webroot -w /opt/lampp/htdocs -d hyperdata.it I can’t remember if I wrote this up anywhere, but I had a real nightmare getting HTTPS support working on this site. Until some kind soul pointed me to Let’s Encrypt. It still took a little while thanks to XAMPP...

Drawing a logo in Logo

I intend to make a video on this, but I’ve not played with screen recording, things to learn. But I will need some kind of chronology so a rough write-up before I forget. Code is over here. If you can do me a better version – any language – I will be made happy. I watch so many YouTube videos...

Global Artificial Life

Caveat : I am very prone to approaching research & experimentation back to front. I’ll have an idea on something I know little about and without doing much/any searching of the literature (Web) I’ll start implementing blindly. In my defence, it’s not always obvious what terms to search for without having a play. Without exception the idea will have been...

Javascript Templating

Text templating/substitution (also known as string interpolation) is really nice to have. I’ve found this very useful in Javascript when building simple browser apps that call a SPARQL server. In fact I recently wrote this up as a paper, with a couple of little demos, proposing a pattern I call Sparql Diamonds. However, I missed a trick. I used the...

Upgrading to Ubuntu 21.10, Impish Indri

Apparently an Indri is a kind of lemur. I’d already done the upgrade on a couple of other machines without any problem, decided it was time for it on my main (office desktop) box. This time there were issues – it said it hadn’t completed. But keeping going at apt upgrade (and whatever else it suggested) without rebooting got there...
