Except SpaceX "competing and replacing NASA" is ... also a meme. SpaceX is essentially the same kind of commercial provider as always, except that they didn't sit on laurels of 1960s ICBM work, and among other things built th

Fun fact - recently it was declared that both Tesla and CCP EVs are to be treated as completely untrusted and not accepted in any semi-secure facilities in Poland (so including pretty much any military location)

Fun thing - SGI specifically used 256 color mode a lot, to reduce memory usage even if you used 24bit outputs. So long as you used defaults of their Motif fork, everything you didn't specifically request to use more colors would use 25

This was the main driver of VGA memory size for a time - if you spent money on 2MB card instead of a 1MB, you could have higher resolution or bit depth. if you had a big enough framebuffer in your display adapter, though, X11 could display

USB4 actually provides both USB 1/2 and 3 tunnelling, but it's incorrect to say it behaves like a hub because it involves needing an appropriate endpoint on the other end. Effectively a virtual cable, iirc, though there are at lea

In my experience[1], the fsck for given filesystem will happily replicate the errors, sometimes in random ways, because often it cannot figure which road to take in face of inconsistency. If anything, OpenZFS built upon that by now document

Probably because optical PCI-E is an old thing by now. In fact, "zero~th generation" of thunderbolt used optical link, too. Also both thunderbolt and DisplayPort reuse a lot of common elements from PCI-E

USB4 is essentially thunderbolt with some new features and some features being optional instead of mandatory.

ZFS-Lustre operates this way. Main issue with opening it further is lack of DMU-level userland API, especially given how syscall heavy it could get (and iouring might be locked out due to politics)

Quite probably should work just fine. The secret is that ZFS actually implements an object storage layer on top of block devices and only then implements ZVOL and ZPL (ZFS POSIX filesystem) on top of that. A "zfs send" is essentia

Apparently it depends to a little bit on how the motherboard is designed, theoretically SP5100 watchdog which is part of the CPU logic in recent ryzens, apparently, is supposed to be enabled if the motherboard is designed with IPMI in mind.

My understanding is that issues in scaling 68k line were already well known by then, same as with VAX (even if crucial people at Digital didn't want to believe). The difference is that 68k was ubiquitous, reasonably cheap 32bit capable

Finder has a lot of signs of being actually a MacOS Classic application - not just the internal presence of Classic-style paths (with ":" separators) but also how Dock was originally developed on MacOS 9.x because the principal de

The missing part is the editor - similarly windows lacked (or hid it way too well) the icon editor, unlike OS/2 where I recall spending hours as small kid making custom icons for games like MSFS

There's generally at least one watchdog device available in most PCs delivered in last decade, but it's not always utilized. Essentially at one point an intel southbridge integrated a basic watchdog on all models, and it started t

A lot of "fun" with those documents is that some of them quite probably were archeological digs on Microsoft side too. For example, the MAPI specs have references to valid parts of the protocols and data structures that are not us

IPv6 explicitly supports all sorts of transitional technology, including being able to map v4 addresses to v6 that are used with translation gateways connecting from v6 to v4 (widely used in mobile networks to provide any v4 access). That s

The firewall is very much a separate thing, and part of the efforts to make v6 properly available for home customers was introducing somewhat standard firewall setup that replicates what people think NAT does for security (and what NAT d

The problem is that the scheduled end of ipv4 was reached in 1990 . But attempts at providing replacement were stymied - IETF went not-invented-here finally getting v6, while USGOV went with CLNS, and meanwhile vendors hemmed and hewed to

It was not possible to make a "superset" of IPv4, if only because one of the early major blockers was that BSD Sockets suck by leaking low-level details of addressing so you'd have exactly the same argument of "why shoul

They also had IPv9 with 20 byte addresses (160 bits) though some of that was consumed for common prefix announcing "this is a TUBA address". It was even something that was already supported by some hardware and software, as it was

Multiple networks do the same - Both T-Mobile (at least in EU) and Orange no longer actually support v4 other than through funky 464 and by funky I mean really funky at times.

US government has finally learnt from how vendors break the mandates and there's now IPv6 mandate if you want to sell to federal government, and waivers are only available for buyers not vendors, and individually every time.
