THE CULT OF PAIN

Computing is indeed a very special field of engineering. Whereas everyone else in the whole known world tries to improve upon his tools in order to make his craft more efficient, software engineers do the literal and complete opposite. Every little problem that can exist is meticulously described, standardised, and almost religiously cherished, with enormous temples of shit erected around them for support and in order to stop everything for falling apart. Imagine if civil engineers used concrete recipes from Ancient Rome. The Pantheon still stands, after all, so the old mix must be good for something. Right? Only if you disregard the fact that everything around The Pantheon has long since fallen apart.

But in computing industry, this approach isn't only frowned upon, it in fact thrives. Teachers force the knowledge of old and laughably bad tools onto their students, when even a mediocre university student can come up with better and more apt instruments. The problems of old instruments are instead put on the pedestal and surrounded with a cult. THE CULT OF PAIN AND SUFFERING. The ability to overcome this pain and move on is celebrated instead of being ridiculed like it should in any sane world. Any attempt to improve the situation is met with hostility. Have you ever seen discussion threads about adding support for Rust into the Linux kernel? Half of self-proclaimed C developers hate even the notion of such desecration of their sacred cow, even though the kernel code quality is already far from ideal and will only become worse with time. I'm not sure bringing Rust in will help the situation, it just might be too late. I'm hopeful it is, because enough is enough.

In fact, the situation around Eunuchs[1] OS family and C programming language might just be the best manifestation of this cult. Consider the following example: one of the famous yet peculiar quirks in C is that variables are not initialised by default. In fact, using a value from an uninialised variable is undefined behaviour, meaning your program is incorrect and your compiler can just throw your code out of the window and replace is with a bag of dicks. There is no sane program that would depend on any sort of behaviour that a code like this results in. Yet, in the 50 years since C was conceived, this feature has not only not been elimited entirely, it has carefully been preserved. Compilers give warnings that a variable might not be initialised. Static code analysers are created and sold as commercial software to allow detecting this kind of errors. Numerous CVEs[2] exist because of someone somewhere having forgotten to initialise a variable. Dynamic tracing and various undefined behaviour sanitisers are used to find the bugs caused by this.

But have you ever wondered, how much it would take to eliminate undefined behaviour caused by uninialised variables in C? About a week's worth of time for a not-so-bad programmer who knows how compilers work. Per compiler, probably, which gives us about a month for all relevant C compilers today. That's it. Tracking variable initialisation and reads in compile time via SSA[3] and adding zeroing in case of uninitialised read is all it would take. And since uninitialised variables containing zeroes would totally fit the description of undefined behaviour, no sane code would be broken by this addition. Yet, it has not happened yet. Not by default and not in a popular compiler, at least. Instead, "features" like this one are celebrated by C programmers. They are considered challenges that one must overcome and learn to deal with in order to become the true programmer. Imagine, if instead of an airbag your car had shrapnel that was launched in your face in the event of collision. Sure, people would drive more carefully, but the idea is stupid and probably nobody would want this.

Lose no hope though. The situation is improving, albeit slowly. Just as it is in science, the adepts of old ways die of old age. Linux was forced to adopt Rust not because it is a better language than C, but because C programmers are retiring en masse and nobody else wants the job. Maybe, the cult will die out just as all cults do.

Just been looking at Substitoot by @virtulis https://substitoot.kludge.guru/

A really neat alternative to #FediFetcher: It's an extension for Firefox or Chrome, that will load missing replies from the home server, when looking at specific posts.

Unfortunately my daily driver is actually Safari (and I use mostly apps for mastodon these days, anyway), so it's not for me, but I think it's pretty cool.

Bit of a long shot, but could my good mastodon follower folk give me some boosts?

I'm starting work on a documentary podcast series about the future of space; renewable/sustainable technologies, commercialism in the sector and the public's perception of it all.

I'm hoping to connect with people who know space to complement my client's contacts, so any signal boosting would be appreciated!

Huge news 🥳

WordPress now has 3,000 ActivityPub plug-in installs.

Which means that on a per node basis, WordPress’s install base is appr. 25% comparative to the size of Mastodon’s install base.

If I were to hazard a guess, WordPress is now the 2nd largest Fediverse server software in terms of active nodes.

In terms of Fediverse server installs, it’s more than possible that WordPress could overtake Mastodon.

My dude. The fact that America doesn’t have functional governance at any level doesn’t detract from the humor of a billionaire sticking his entire $44b shoe in his mouth and chewing on it while dril dunks on him repeatedly.

#Tunng's "Comments of the Inner Chorus" is literal magick.

When I first heard it, in 2006, it was so fresh and wonderful, I still listen to it in awe.

I wish they kept making music this brave.

Sorry, but you can't convince me that the test of a reusable rocket system is supposed to involve destroying the launch site—which was reusable on every prior generation of space flight technology—and launching debris thousands of feet away.

#SpaceX is not a serious company, it's a clown show, and it should not have a single dollar in government funding, much less billions.
