Visual programming environments need more fun backgrounds.

The #diy #keyer guide now includes a section on layout optimization. With ants 🐜!

I've built a tiny hand-held #keyboard. It's like Meta EMG wristband (www.youtube.com/watch?v=wteF...) but actually working.
Also comes with instructions on building your own one! github.com/mafik/keyer/

My mouse pointer seems to be possessed. Is this the proper way to exorcise your PC?

Here is a fun trick: signal handlers can perform surgery on the stack & registers for the interrupted thread. It can be used to inject fake function calls or steer the execution arbitrarily.
It's almost like a built-in programmatic debugger that can be triggered with a "signal()" call.

Skyrim Alchemy macro is ready!

Automat can now farm alchemy ingredients in Skyrim! It scans the shopkeeper's inventory, buying every "Giant's Toe" & "Creep Cluster". When done, performs inventory reset glitch & starts over.
Another step towards fully automated alchemy grinding.

Also for squiggly connections like this one. If I know the turn radius of the cable and horizontal displacement that I need to make, OtherLeg tells me how much vertical space the squiggly part will take.

Here I use it for placing the purple segments with fixed gaps (each segment is a pair of arcs with subtly different angles).

Here is a tiny but useful function. Given radius of a circle and length of a leg of an embedded triangle, it finds the length of the other leg. It may seem silly but it really makes it easier to think about geometric problems. It's like LERP for geometry.

Some of notes made while making sense of x86 conditions.
The worst part for me are the JB & JNB conditions which have dual use. They are used for comparing numbers and for "unsigned overflow" checking. This makes it hard to find a reasonable visual metaphor as it also has to exhibit this duality.

Do you know what's the difference between JA (jump above) and JG (jump if greater)?
Conditional instructions in x86 come in 16 variants with a bunch of interesting symmetries between them. Here is a visual language that attempts to exploit those symmetries to make their meaning more intuitive.

Self-modifying programs can store variables directly within their instructions. I guess this has some interesting implications.
