For anyone who wants to try out time-limited sessions, pam-session-timelimit is now in Debian unstable and Ubuntu lunar:

https://packages.debian.org/sid/pam-session-timelimit

I've also finished a patch to make pam_time integrate with pam_systemd, which after 20+ years makes it possible for pam_time to enforce the end of sessions and not just their start times:

https://github.com/linux-pam/linux-pam/pull/562

Started Mastodon API support, so you can use Mastodon-compatible apps to access #snac accounts. What works so far: login, private and public timelines, full post information (replies and ancestors), liking and boosting posts. Things that don't work yet but eventually will: following accounts, posting and replying to messages (I still have to figure out how some things work, like posting images), notifications (needs some internal support), the instance timeline (snac does not have one, but it can be simulated with not much effort) and probably many other things. Things that will never work: bookmarks, pinning, a federated timeline, many other things that I don't remember right now. Please note that if you want to use this API in your instance, you must add some lines to your HTTP proxy configuration, see the snac(8) (administrator documentation) manual page. I'm doing my tests using the #Tusky (which sometimes crashes, surely my fault), #AndStatus, #Fedilab and #Husky Android apps. Success or failure reports will be appreciated.

Fixed some buffer overflows (contributed by Saagar Jha).

Fixed overzealous rejection of some local boosts.

It's expensive to be poor. It's ironic but true. You get charges and fees for everything. Higher interest rates. Overdraft fees. Late fees. Having only enough to buy what you need right now instead of buying in bulk. Losing your job because you can't afford to get your car fixed. Losing your car because you don't have a job. Even your mental faculties are drained, as you are forced to continually eat low-nutrition foods, "sleep" in miserable conditions, and be exposed to toxins and lack of medical treatment. The lack of liquidity wipes you out. Life really does kick you while you're down.

You can't tell someone trapped in that vicious cycle to "just" get a job or "just" make responsible decisions. Sometimes, no amount of good decision-making can stop the vortex sucking them down. So the next time you are tempted to place moral judgment on someone who lives in poverty, think twice.

“The reason most public transportation is seen as ‘losing’ money is precisely because it charges for trips. If you don't charge fares, suddenly it can't ‘lose’ money. It just costs money, the same as the roads.”

The purge ttl for stray global objects has been shortened.

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?

Your work is impressive. I love it.

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.

Text (in interview format): MG: What would you say to those who feel they donated under a false pretense and might feel wronged? SM: To those who donated I would again stress this wasn't demanded of them. I'm sorry they feel wronged, but they chose to DONATE. It doesn't magically become a loan because they regret it now. And WHY do they? Because an Author told a Story? The only difference now vs before is I'm alive. They'd rather I be dead? Then they'd be happy about donating? That's what it seems like they're saying, they're cruelly wishing death on me.

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.
