"An urgent warning about the open web’s shrinking commons"
Vint Cerf,Cindy Cohn,Jon Stokes (ars technica),and me. a take:
"remake the connective tissue—technical, legal, and economic—that made the web an engine for learning and civic life.
Keep the network interoperable.
Safeguard libraries.
Restore competition.
If the open web can still be a place where truth moves farther and faster than lies, the next chapter can still be written with those principles in mind."

@amin it's really nice, and it's a forgiving non-stressful recipe. Takes a while for all the baking steps, but most steps are independent and don't require a lot of attention. It's hard to mess up. And, it's impressed just about everybody I've ever served it to. It punches far above its weight in terms of impressiveness to difficulty. You can even use canned enchilada sauce if you're in a hurry, it turns out fine.

You need to set your clocks back again.

Multitasking On The Humble Z80 CPU
Multitasking is something we take for granted these days. Just about every computer we use, from our desktops to our phones, is capable of multitasking. It might sound silly to implement multitasking on lower-spec machines from many decades ago, given their limited resources, but it can be done, as [bchiha] demonstrates on a Z80-based machine.
[bchiha] has achieved pre-emptive multitasking on the TEC-1G Z80 computer, a modern reimagining of the classic Talking Electronics TEC-1 from the 1980s. The proof of concept code allows running up to eight separate tasks at once. Task switching runs on interrupts, triggered at approximately 50 Hz. When an interrupt fires, the CPU registers are transferred onto that task’s stack, and the next task’s stack is swapped to the stack pointer to allow execution of the new task to proceed. There is an overhead, of course, with [bchiha] noting that the task swapping routine itself takes about 430 clock cycles to run in between tasks.
Multitasking took some time to appear on home computers for good reason—it’s not very useful unless you have a machine with enough power to practically run multiple tasks at once. While a Z80 machine like this can do multitasking, you’d better hope each task is pretty tiny to avoid each individual task taking forever to run.
[bchiha] has made the simple multitasking code available on Github for the curious. We’ve featured multitasking work on other unconventional platforms before, too, like the Arduino Uno. Video after the break.

@argv_minus_one @MelissaBearTrix Red and Green are the most common colourblindness, I've heard people with that kind rely on the position of the lights (top/bottom or left/right) rather than the colour. Yellow shouldn't be too bad because it should show up a lot brighter than the other two, but I agree that green should be more blue (and in some countries it is). Violet wouldn't be great because our eyes are much less sensitive that far over in the spectrum.
