Amusingly similar to the much more recent slide decks about the x86 port, e.g. https://vmssoftware.com/docs/State_of_Port_20171006.pdf

Don't use die.net! The manpages there were last updated 10+ years ago. It's very unfortunate that that site does so well on Google.

I know this is a completely unimportant tangent. But I'm always amused that systemd skeptics insist on the "SystemD" spelling. Where does that come from? I never see anybody talk about NtpD, InetD or VsftpD. But somehow syste

Debian does not ship the AAC codec, due to legal quagmire surrounding the necessary code. The same probably goes for Ubuntu. That might be the cause of at least some of your problems. https://tookmund.com/2024/02/a

IXI was bought by SCO, and they shipped X.Desktop with their Unix releases. See e.g. https://en.wikipedia.org/wiki/OpenServer

That was very lucky then. USB parallel ports adapters are only intended to work with printers. They fail with any hardware that does custom signalling over the parallel port.

They might just be encrypted with a customer-specific key. That wouldn't surprise me.

That's not really true. If you link a shared library that was compiled with -ffast-math, that will affect the entire program. https://moyix.blogspot.com/2022/09/someones-been-messing-wit...

This chess piece likely predates the introduction of the bishop. The set would have had elephants instead, which would have been depicted with two tusks. See e.g. https://www.thehistoricgamesshop.co.uk/early-medieval-chess..

I think they must be referring something in an unstable-series kernel. I don't remember anything like that, but I only ever used the stable kernels. (Back then, there were separate stable (2.2.x, 2.4.x) and unstable (2.3.x, 2.5.x) bran

I've used nip2 when dealing with giant images. It's a weird tool, but it's designed for that kind of work. https://github.com/libvips/nip2

That makes sense when you realize that what C folks care about more than anything else is _ABI compatibility_. Changes to language or toolchain are acceptable as long as they don't change the ABI. E.g. consider the hemming and hawing a

And it's a very poor rendering of a man page. man can generate HTML or PDF output if you want it: man -Thtml ls > ls.html man -Tpdf ls > ls.pdf

The cited RCS paper is actually somewhat contentious among Unix greybeards. They claim the paper compared RCS against an obsolete version of SCCS. Supposedly a contemporary SCCS would have easily outperformed RCS. Of course, RCS was freely

Lots of software links both liblzma and libcrypto. As I read Andres Freund's report, there is still a lot of uncertainty: "There's lots of stuff I have not analyzed and most of what I observed is purely from observation rathe

Flagged: How is this "via a project dev"? Which project? The guy doesn't seem to have anything to do with the discovery of this backdoor, and he just summarizes Andres Freund's announcement.

Focusing on sshd is the wrong approach. The backdoor was in liblzma5. It was discovered to attack sshd, but it very likely had other targets as well. The payload hasn't been analyzed yet, but _almost everything_ links to libzma5. Firef
