The purge ttl for stray global objects has been shortened.

In the HTML interface, don't show the collapse widget for non-existent children.

Added support for HTTP signature pseudo-headers (created) and (expires), that are used by some ActivityPub implementations (e.g. Lemmy).

I don't see any threat here. They've written their own implementation of #ActivityPub that doesn't connect outside their network, well OK for them. They could have implemented any other protocol to connect their servers between. Why should we care, and what difference does it make for the Fediverse?

Jon Corbet (LWN.net) on the AI crap that is waiting for us in 2023:

Perhaps this flood of content will prove beneficial [...]. But that outcome does not seem highly likely in the near future. Instead, we're likely to see code submissions from "developers" who do not understand what they are posting; this code could contain no end of bugs and, potentially, license violations. Cut-and-paste programming has long been a problem throughout this industry. It is far from clear that automating the cutting and pasting is going to improve the situation.

AI-generated text has its own challenges. Our mailing lists and forum sites do not lack for people trying to appear authoritative on subjects they do not really understand; how many more will show up when it is easy to get a machine-learning system to produce plausible text with little effort? Even the most ardent believers in the "last post wins" approach to mailing-list discussions will get tired and shut up eventually; automated systems have no such limits. How long until we have a discussion on, say, init systems that is sustained entirely by bots?

Pobrecita. A ver si se le cura de una vez.

I'm thinking about adding some new features to snac, the minimalist ActivityPub server written in C. As these features are opinionated and probably even controversial, they will be off by default. These are the ideas:

First, add an option to automatically drop all announces (boosts). Unless your affinity with the people you follow is deep, boosts are just (usually) tangentially interesting, probably flooding your timeline and just forcing you to spend more and more time inside the social media space. A variant of this would be to make this option not global, but by actor, so that you can 'boost-mute' only those adorable but annoying fellows that are particularly trigger-happy to the boost button (implementing the option this way is more work for me, but not that much).

Second, add an option to drop all messages that are not public nor mentioning you. That is, filter out those infamous 'follower-only' messages. People use to engage in these follower-only conversations, so you only receive these chat fragments without context (unless you also follow all the people involved) and they are purely noise. In my opinion, follower-only messages are a very bad idea that just pollute the space (and this is why snac doesn't implement them and never will).

Third, add an option to drop all replies to your messages from people that you are not following. This would prove useful for very popular, mostly announce-only accounts. I agree that it's a bit elitist and probably toxic, but also helps in spending less time inside the social networks and more time painting or writing or taking the dog for a walk.

What do you think?

If you program in C, you've probably used what is called the ternary operator a million times in expressions like this:

    value = user_value ? user_value : default_value;

What you may not know is that, thanks to a gcc (and others) extension, you can abridge that expression to this:

    value = user_value ?: default_value;

I find the article interesting not only for C++ "peeps", but for us greybeard C programmers as well, who learnt the language in the eighties. Remarkable sections in the document are:

- Use struct wrappers for strong typing (I've never done this, but it's interesting; accessing the components inside the structs may become a bit tedious, though).
- Initialization in C99 (I haven't used this to its full potential).
- Don’t be afraid to pass and return structs by value (as an old fart, I always pass pointers to structs, and this section reasons otherwise for small structs).
- Named optional arguments (or, as the author more accurately describes this, the "option bag").

Researching mines in northern Spain I came across this curious object. It's a canary cage designed to keep the canary alive in the event of a gas leak. If a miner saw the canary laying at the bottom of the cage it was time to abandon everything and leave the mine, but not without first closing the latched glass door and opening the valve of the oxygen bottle to save the bird. A miner would do that on their way out and take the bird with them. It's a signifier of the miner's legendary sense of solidarity, no lives lost to the mine on a miners watch. A solidarity that was also crucial in the fight for workers rights, creating safer and more humane working conditions, achievements of unionization and solidarity that some of us still enjoy today.

Linux's strcmp() For The m68k Has Always Been Broken:

The m68 hand-written assembler version of strcmp() has always been broken: it returns the difference between the first non-matching byte done as a 8-bit subtraction.

That is _almost_ right, but is broken for the overflow case. The strcmp() function should indeed return the sign of the difference between the first byte that differs, but the subtraction needs to be done in a wider type than 'char'. Otherwise the ordering isn't actually stable.

Actual artists on Artstation, fed up with AI generators scraping their work, started posting "no AI" logos (the classic circle with a line through it) in protest.

And since "trending on Artstation" has become a common prompt among AI users, their results are all getting contaminated, as the algorithm just assumes the logos are part of the image. They're all upset about the "attack" now.

I've just released version 2.15 of snac, the simple, minimalistic ActivityPub instance server. This time is mostly bugfixes:

Fixed bug in message posting that may result in 400 Bad Request errors (contributed by tobyjaffey).

Fixed crash and a deletion error in the unfollow code.

Added configuration files and examples for running snac with docker (contributed by tobyjaffey).

Serve /robots.txt (contributed by kensanata).

Use the Fediverse sparingly and wisely.
