Floppy reliability dropped of a cliff in the mid-90s. It came to a point where it wasn't unusual to see I/O errors even on completely new floppies.
But with older drives and older media, produced to a higher standard, they were pretty reliable. (After all, IBM invented them to store CPU microcode, they had to be.)
I'm sad that the building instructions link doesn't work. I'd love to see them.
Nothing to do with the VM. The game was designed that way, navigation is part of the puzzle.
I think that's out of date. The banner at the top of the page says "you can request a free license for version 5.4 from us." According to archive.org that was added later than the text you quoted, somewhere between 2022 and 2024.
In the early 90s Microsoft distributed the full Win32 API documentation as a WinHelp file. It felt very much as hyperlinked man-pages. Super fast too, even on machines of the time. WIN32.HLP can still be easily found, but modern Windows versions no longer ship WinHelp :(
"Shipping" wouldn't be a problem, they could just run it from a network drive. Their PCs were networked, they needed to test deathmatches after all ;)
And the compilation speed difference wouldn't be small. The HP workstations they were using were "entry level" systems with (at max spec) a 100MHz CPU. Their Alpha server had four CPUs running at probably 275MHz. I know which system I would choose for compiles.
Even then it was not universal. For example, that Apple I ad that got posted a few days ago mentioned that "the system is expandable to 65K". https://upload.wikimedia.org/wikipedia/commons/4/48/Apple_1_...
Even in computing the binary definition is only used with memory sizes. E.g. storage, network speeds, clock rates use the standard definition.
All of Microsoft's applications used to do that! The 16-bit versions of Word, Excel, PowerPoint, etc all were implemented using bytecode. That technology was only integrated in Microsoft C and made public in 1992 [1], before that the Microsoft applications group used their own private C toolchain. A copy of it can be found in the Word 1.1 source release [2] ("csl").

Rosetta uses software emulation for x87 floating point. That's slow, but in practice that doesn't matter much. Mac software never had a reason to use x87 FP, every Intel Mac had at least SSE3 support.
The signedness of `char` is implementation-defined, it is signed on x86 but unsigned on ARM. So assigning a plain char to a wider integer type is suspicious, did the programmer expect sign-extension or zero-extension?
The Nintendo GameCube and Wii also had IBM CPUs.
I wouldn't assume ABCL runs on Android. It's not listed as a supported runtime on their website.
A lot of game devs of that era sadly treated the Adlib/SoundBlaster OPL2 chip as nothing more than a very poor MIDI synth, but it was capable of much better. For example, listen to some of Stéphane Picq's music. https://vgmrips.net/packs/composer/stephane-picq
In those days malloc would use sbrk to allocate memory. And yes, mmap was designed to memory map files. Using it to allocate anonymous pages came later.
Are they in widespread use? They were deprecated in 1995.
I always wondered how secure AS/400 actually is. The original implementation might have checked tag bits in hardware (I don't know), but the current (PowerPC) implementation relies on the compiler generating a "check tag bits" every time a pointer is dereferenced [1]. So it seems that any arbitrary code execution vulnerability would be absolutely devastating. And the "SLIC" is not a small microkernel -- it also contains the compilers, the database and other system components. It'd be hard to believe there would no exploitable bugs in there.
Debian woody (2002) shipped gnustep. I tried it back then, but as far as I remember, it was weird enough that anybody who didn't have NEXTSTEP experience would bounce right off. The floating menus, the weird scrollbars, etc. There were also no non-trivial applications that I can remember.
People back then were looking for something that would be familiar to Windows/Mac users. GNUStep (at least at the time) was not interested in being that.
Security researchers rarely fix bugs. They don't see it as their job, and it requires a very different skill set than finding or exploiting them anyway.
From that article:
While similar, it is not the widely reported Asrock motherboard problem, as the motherboards we use are of a different make
The Windows 2000 launch is closer to the release of Altair 8800 than it is to today :/
Right, people forget that the xz-utils backdoor happened to a very traditional no-dependencies C project.
zlib comes with a basic ZIP implementation (libminizip).
As a user you can only use the polyfill to replace the XSLTProcessor() JavaScript API. You can't use the polyfill if you're using XSLT for XML Stylesheets (<?xml-stylesheet … ?> tags).
(But of course, XML Stylesheets are most widely used with RSS feeds, and Google probably considers further harm to the RSS ecosystem as a bonus. sigh)
It's disheartening that this Chrome dev in the comments shows himself to be completely unaware of the RSS ecosystem...
With an old and conservative project like Emacs, the reason could just as likely be that it was done that way for the NEXTSTEP port in the early 90s and that nobody revisited it since then. Oftentimes the reason is just legacy, limited manpower and "don't fix what ain't broken".
Somebody spent time and money to make vim posix-compliant: https://vimhelp.org/vi_diff.txt.html#posix
Another fascinating aspect of COBOL is that it's the one programming language that actively rejected ALGOL influence. There are no functions or procedures, no concept of local variables. In general, no feature for abstraction at all, other than labelled statements. Block-structured control flow (conditionals and loops) was only added in the late 80s.
The decision to now show seconds dates back to Windows 95. Back then the motivation was not power saving, but rather to allow the code related to the clock and text rendering to be swapped out to disk on a 386 with 4MB RAM...
