A physical jumper or switch to enable/disable writing to the firmware flash could end a lot of these kinds of problems.

Despite seeing code early in the series, didn't see any code that would actually put pixels on a screen, or even to write a static image into a file, at least not within the first 6 or 7 units. Somewhere around that point there is some

Playing around with classic three layer feed-forward classifier networks decades ago, it became apparent that successful networks tended to converge on a sort of standard solution: layer 1 would be various linear discriminators - each node

Years ago I tried starting out with 5 wpm and 'working up', and just barely passed the 13 wpm test to get the 'Advanced' ticket. Only thing that stopped me getting Extra was that 20 wpm code test, that was still a thing

The kind of logic cell used uses very little power to maintain itself in one state or the other, but it costs a little energy to flip between states. The faster you clock the CPU, the more often those flips happen. Heat can only flow out of

You'd need something like a 'stop' state, distinct from reset. The system power supply would have to release the STOP line to allow the computer to continue processing, and the power supply would also have to assert STOP on e

It's kind of maddening, after having the space to Just Think during the WFH days, to be back in the office and any time you stop typing for more than 30 seconds risk being interrupted by co-workers who think you're Not Busy.

FDCs were tricky things. When reading you had to pick up a byte every 8 usec, when writing you had to be ready with the next byte in the same amount of time, and a whole sector's worth would need to be dealt with without interruption.

It's especially useful when you have several processes that communicate with TCP or UDP. 'lsof -i :<port>' will quickly show if you have the connections you expect to have.

I sometimes use tar when I need to transfer a bunch of files using a USB stick. Most USB sticks I encounter are FAT (or rarely, NTFS) and the permissions get trashed if bare files are copied. Tar saves me from having to repair the perms on

'lsof' is another one that I can't do without.

Maybe tree covered ground makes a more effective source of the rising-up component of this process. That relatively warm, negatively ionized rising air might be much diminished over a frozen lake or open plain. Otoh, it'd probably be

And then of course, there are the "ice making" sounds that do come from below. And different lakes and ponds even seem to have somewhat different voices in that way.

Not sure they mean reliability in the sense that the floppy is inherently reliable, but rather, reliable relative to "cloud" storage. Presumably any tec that depends on one's own attention to maintenance, rather than the co

When you find yourself putting a sticker that says 2030 on your license plate, chances are 30s won't mean 1930s very much longer.

The "ohs". Twenty-ohs. Rhymes with that oaty breakfast cereal.

by greenbit 2y ago
How about the 20-ohs? Think of how individual years are named. Back in for example 2004, "two thousand and four" was probably the most prevalent style. But "two thousand and .." is kind of a mouthful, even if you omit th

When a 10 year old can notice that certain sodas induce a nasty stomach ache, and that the thing all of those had in common was BVO, and that ones without it did not .. makes you wonder why BVO was ever considered safe. (I've been ac

The thing I never found satisfying was this notion that the air over the top moves faster because it has further to go - in what way does the length of a path that lies in the air's future have any effect on its speed now ? As if th

I'll pile on with a dose of "people keep overestimating ability of these things". They do a good job at imitating the ramblings of human beings (you are what you eat!) but computer code that needs to do anything more serious

Wondering, is the resulting coffee thick because a certain amount of the grounds are pulverized enough to pass the filter? Would be interesting to centrifuge some and see if that's the case. Anyway, might not actually be an issue, give

Wasn't there a way to tell BASIC to save in ASCII, rather than tokenized? Something like sticking ",A" onto the end of the save command? Or maybe I'm thinking of gwbasic ..

Heh - 'core 2 duo' .. that's about 2005 vintage isn't it? Should be nice and smooth on modern hardware.

It's kind of feeling a bit like an intruder? There probably is a name for that.
