I've been trying to figure out whether the mainframe business is being spun off or retained as part of this split. Haven't been able to figure out whether IBM even manufactures this equipment. I know they outsource the chip fab no

20 kg of hydrogen is about 2400 Mj. The Class 319 has 1 MW of motors. So the hydrogen fuel will run the train for 40 minutes at max power. Maybe 3 or 4 hours in typical use? 20 kg may not seem like a lot, but hydrogen has three times the en

Maybe it's better now, but CUPS used to be a nightmare. I still avoid it whenever possible. Eric Raymond did a good job of describing just how bad it was. http://www.catb.org/~esr/writings/cups-horror.html

Original reddit shows me 12 threads "above the fold" (without scrolling). Current old.reddit shows me 8. New reddit shows me 3. The extra space is taken up by useless garbage like "give award", "share", and &qu

Varargs was not part of the language originally. If you look at the source code for printf() from Unix v7, I think you'll find it accesses its arguments by indexing off the address of the first one. I don't remember when varargs c

You know it outputs to stderr, right? Also if you give it the option "-o -" it doesn't do what you might expect. Other than that I grep the output of strace all the time and it works for me.

The comment "initialize the utmp structure" is wrong. You have declared the struct here but it is uninitialized. And there is no point in setting the locale, since your program never uses it.

You know what I don't get? Why is Edward Snowden, who exposed these crimes, being treated like a criminal?

Another fun fact I discovered the hard way is that many APC UPSes refuse to go back into bypass when they are supplied by a small generator with a dirty waveform. We had quite a few APC units in the 1990s and 2000s, and I had the impression

What's the problem with copyright? Assuming the rights owner can be found and midi transcriptions made of the piano rolls, why would it be legally any more complicated than publishing sheet music? Of course any public performace would

These were officially called "variant" links. Within Apollo R&D they were known as "deviant" links. They got the idea from Pyramid. Apollo's downfall was that they clung to their proprietary OS long after everyo

This is not a coincidence, nor is it an uncanny ability to see into the future. Tim Berners-Lee, who invented the URI/URL naming scheme, worked at CERN, which mostly used Apollos at the time. He modeled URLs after the Apollo naming sch
