There is also the true story from the first Scientology vs. Internet clash, someone trolled them that their files were being hosted on 127.0.0.1, under a court ordered deposition they tried to find out who was running this server with their secret files (because yes, they'd looked, and they were there)
True that! Keith Henson's legendary alt.religion.scientology loopback trolling story, with hilarious deposition transcript, in which he patiently explains how 127.0.0.1 works to astonished Scientology lawyers:
>Just be glad you didn't have to explain an in joke about ftp sites, the local loopback address, and a troll, in a deposition, under oath, to Scientology lawyers, like Keith Henson did.
[...]
>Henson: (patiently) It's at 127.0.0.1. This is a loop back address. This is a troll.
>Lieberman: what's a troll?
>Henson: it comes from the fishing where you troll a bait along in the water and a fish will jump and bite the thing, and the idea of it is that the internet is a very humorous place and it's especially good to troll people who don't have any sense of humor at all, and this is a troll because an ftp site of 127.0.0.1 doesn't go anywhere. It loops right back around into your own machine.
>Lieberman [not getting it]: So the idea here was to make the church think that this person had an ftp site and to take action against him and, in fact, he didn't have it; is that your point?
>Henson: Oh, it's really humorous, and I picked up on it and instantly added something to extend the troll. Extending the trolls like this is an art form of the highest order.
>Lieberman (acidly): I see. So this is part of your art form where you say, "don't you expect the 'ho to blow a gasket?"
Trolling is typically done on lakes with fishing lines cast from the back of a boat. A trolling motor sets the boat speed. Trawling usually takes place at sea, with larger boats and wide nets.
Trawling is done by dragging nets along the seabed causing massive damage with huge inefficient polluting fuel-guzzling 1000 horsepower diesel engines.
Trolling is as the other guy says where you putter along with minimum effort and a tiny engine pulling a couple of baited lines through the water, seeing if you pass through a patch where anyone bites.
Trawling is far more analogous to the AI scrapers, hammering the absolute shit out of the ecosystem and throwing almost everything they scoop up away with no regard for the consequences.
Foxley gives the manual procedure for sizing the lost+found directory on the aforementioned page 52.
I have the 1986 edition of Fielder's and Hunter's UNIX System Administration and it does not mention any such command in its discussion of lost+found in chapter 3. It references AT&T Unix System 5 Release 2 (or 'UNIX 5.2' as the book puts it).
But Google Books tells me that their later 1991 update, referencing Release 4 and with an updated title to match, does indeed mention mklost+found. So that looks like something that appeared in Release 3 or 4.
I used to port Unix for a living (V6 thru SysVr3) I know it was in Vr2, and I have a man page that says "(last mod. 1/15/87)" which would likely make it SysVr1 or earlier
My guess is that it was undocumented until Release 3 or 4, so the book authors simply never found out about it. Andrew Tanenbaum knew about it at the same time as the first Hunter and Fielding book, but likely this was word-of-mouth stuff.
The cache coherency protocols that sit between the CPUs and DRAM always essentially "use a mutex": when a cpu wants to write it broadcasts to all the other CPUs and either gets the latest copy from whoever wrote it last and shoots down any read-only copies in other CPUs or reads it from DRAM (or converts a read only copy to be writeable)
This happens on every memory access, so the thing you want to avoid is ping ponging writeable cache lines between CPUs (especially before you have a chance to actually write it) - LL/SC instructions sit on top of these protocols and allow instructions to tell is a cache line had been "stolen" before you have a chance to write it
When I first started doing chip design my boss paid more for tools per year than he paid me ... now days open source tool chains are leaping ahead ... I don't need a boss (or VCs) in order to design chips
I'm not sure they're all that simpler, the basic plumbing probably hasn't changed much, it's just that modern fabrication tech means you can hide all the complexity inside
Doesn't matter. In Scotland, we have variously a former BBC news reader who was married to a politician and a Gaelic child actor (often on BBC made programmes) whose father was MP for the Outer Hebrides and whose uncle was a BBC news reporter. You could argue neither of those were political roles. It comes over as very cliquey and nepotistic to me. There are millions of people in NZ, many of whom can't get into these circles, and folk at the top of politics and media hang around with each other. Then the public wonders why they come over as out of touch.
Ardern's ?uncle was also a big noise in the Mormon church. Used to run the Pacific region, where it has major influence in countries like Samoa and Tonga. She's well connected.
I lived on Dana St in Oakland at the Berkeley border, we continually found lost and confused people - the street continued down our block and stopped, reappeared after a jog a half block away, numbers got smaller as it went south, over the border numbers got smaller as the went north and the street disappears for 3 blocks as it crosses Telegraph Ave (literally where the telegraph was installed in a straight line) diagonally - 4-5 pieces with numbers going in opposite directions.
Even wore our portion was originally in Berkeley, the border was moved 100 years or so ago so that someone could open the closest bar to the campus when Berkeley had more stringent liquor licensing
If you can print small enough with this technology I'm pretty sure you can make transistors - sort of 1980 era transistors, not very dense, but if you are printing bulk materials you can build in 3D rather than 2D, make interesting numbers of transistors, cpus in everything!
