OpenBSD pkg_add -u has seen a huge improvement a few months ago by using the package quirks as a signature database, allowing to check for update without having to download each installed package signature on the mirror (the signature is contained at the beginning of the package file).

Unfortunately, I think this isn't working on 7.2 at the moment due to package quirks not being regenerated every time packages-stable has new packages, so the old strategy is used because quirks isn't up to date.

This should have worked for people upgrading from 7.1 to 7.2 because packages-stable didn't exist yet, because the quirks was correct.

This should be fixed in a few days (mirror propagation).

Now this is interesting: an ActivityPub server implementation by @grunfink written in C that only depends on `libcurl` and `libssl`:

Should be easy to package it up for Guix. Code looks nice too!

Is #RSS for #Gemini a thing?

It shold be.

Here on #Mastodon, I don't ask people to subscribe or #follow. I encourage people to *INTERACT* (following is one tool to facilitate that). My measure of enjoyment of the #Fediverse isn't my follower count; it's the kind of interactions I've had.

So to all the new people that follow me that I haven't interacted with: that's totally fine! But I'd love to hear from you - reply to this and say hi!

Mastodon smaller than Twitter, but the quality and FUN of interactions here is SO much higher!

Ah, the suffering.

So... what if:

1. #Tumblr adds #ActivityPub support as announced
2. Users choose Tumblr as a safe choice (because it's been there for more than a decade, what could go wrong?)
3. Tumblr feels satisfied with more users, and then starts to think AP support is redundant for them
4. They cut AP support
5. Ugh.

I was running #OpenBSD -current and changed my installurl to go to a mirror that had more recent snapshots than those on cdn.openbsd.org. When I switched to 7.2-release, I just copied over installurl from my backup.

Now I'm running firefox 107 on 7.2-release (with patches) and it barfs out these 9 MB core files (and sometimes dies) when I open Mastodon. The timestamps on the firefox.core files seem to match up with timestamps in /var/log/messages with messages like:

/bsd: firefox[925]: pledge "rpath", syscall 5

I haven't changed anything under /etc/firefox.

Anybody else experiencing this? And why is cdn.openbsd.org almost twenty days behind (at least regarding packages-stable) the other mirrors? Just another case of ``should have stuck with the defaults''?

I hate feeling really dumb about this, but how do I use a keyboard combo to make an "ñ" on #OpenBSD?

I can't help but notice many toots from helpful newbies encouraging you to support the Mastodon Patreon.

It's fine to do that but understand it goes to just two big instances and the official Mastodon dev team.

It does NOT trickle down to YOUR instance. If you want to support your server, donate to it directly. Nearly all the costs of the explosive growth of the past few weeks is borne by local instances.

Wow. This guy doesn't understand the first thing about what makes Ozark a great show:

"This is a show that has built its entire foundation on dislikeable characters – truly, truly despicable human beings. The Byrde family, from top to bottom, has little to no redeeming values."

#GordonShelly

https://influxmagazine.com/ozark-season-5-review/

#Ozark

I think this show works because the main characters are horrible persons (among other things, of course).

@angel
That's his line. It might make sense if you only watched the latest seasons. The genius of the show, like Breaking Bad, is that the main characters start off as normal and rather likable people, who are slowly but surely corrupted by the neverending series of trolly problems they face.

@angel
Remember, everything the Byrds do in the Ozarks happens because Marty's business partner got them into bed with the cartel without his knowledge. Ruth especially is a fundamentally good person, raised in an inescapably shitty hole, and almost everything she does is an attempt to pull herself and her cousins out of that hole.

I totally agree with you, it's their descensus ad inferos what make the show fascinating, as they start being good people and end up being cold monsters because of the circunstancies. The case for Ruth is specially heartbreaking because he is how she is due to poverty and family issues, she tries but never succeeds.

Here’s an idea: let’s call people “people” on the fediverse instead of “users” whenever we can.

Compare:

“There are 42 users on this instance.”

vs

“There are 42 people on this instance.”

Which acknowledges our humanity more?

Language matters. We don’t need to perpetuate mainstream technology’s othering/colonial framing of “us” – designers/developers/other “clever folks” – and “them” – the users (usually one step removed from “dumb user” and usually the ones who get used).

#peopleNotUsers

There is no univocal relation between users and people in this network (nor in any other, for that matter). Some 'users' may belong to the same person. Some 'users' may be bots.

What you have in you hard drives are users (or accounts), not people.

TIL that you can have a full-path soname in a dynamic library, so that binaries linked to it can find it even if it's in a non-standard place:

"...the problems with Twitter are not engineering problems. They are political problems. Twitter, the company, makes very little interesting technology; the tech stack is not the valuable asset.

I suggest that, instead of keeping the "thread" format as a chain of brief messages (which were used in Twitter to avoid one of its severe limitations), you move all your valuable information to a more suitable format, like a web page or a blog entry or somewhat similar.

Then you can publish here links to your creations for us to enjoy.

Fast character case conversion (or how to really compress sparse arrays):

Converting strings and characters between lower and upper cases is a very common need.

In particular, case conversion is often used to implement case-insensitive comparision, an operation that is often present on the program's fast paths as a part of data container lookups and content manipulation.

So it is usually desirable to make case conversions as fast as possible.

In this post we are going to look at one of the options - very fast case conversion using compressed lookup tables and also at some options for compressing these even further.

Stop writing Twitter threads! (Pierre Equoy):

So please, please, if you plan on writing something longer than a bad joke or a snarky comment, do not use Twitter. Your ideas, your findings, your knowledge deserve better. Put your thoughts on your own website or blog, and share it with the World using whatever social network you see fit.

https://pierre.equoy.fr/blog/posts/2022/10/stop-writing-twitter-threads/

One problem with the cinema business is that customers are supposed to pay for the product *before* they get to find out if it's any good. This skews the market towards safe and familiar productions, rather than brave and innovative ones. It forces film-makers to shoehorn experimental ideas into established "franchises", instead of being allowed to tell new stories, with new characters in new worlds, where their ideas can be judged on their own merits by an audience with no major expectations.

Insightful thought, but... doesn't this apply to mostly all artistic disciplines, e.g. books? You always pay before being able to know if you like it or not.

I was about to say it happens on music records at well, but the economic model has changed on this as you don't buy those things anymore.

Perceptual hashing (Matt Rickard):

Hashing algorithms map data to an arbitrary fixed-size value. Most hashing algorithms actively try to avoid collisions – e.g., minimizing the probability of two different keys having the same hash. Perceptual hashes do the opposite – they maximize collisions by creating some dimension of data locality – similar keys have similar hashes.

Something that needs to happen in Sci-Fi: Crew powers on the alien computer to be greeted with an obvious countdown timer under alien text.

Panic because countdown.

After the countdown has elapsed... no explosion. They look at the computer and it's finishing up playing a short animation before going to a login prompt.

And that's how they learn about alien bootloaders and OS selection timeouts.

No sé si será el caso, pero he visto que los programas hechos en Go ocupan locuras como esas.

Let's talk HTTP status codes and Service Workers. A 🧵.

4xx HTTP codes are "client error" codes: the server is telling the client (often the browser) that the client did something wrong: requested a resource that doesn't exist, or which is forbidden, for example.

5xx HTTP codes are "server error" codes: the server is informing the client that the server did a boo boo: some internal error, gateway timeout, etc.

Okay, which code should a Service Worker use when it itself fails?

#WebDev

1/n

My opinion is that it should return a 5xx as a way to tell the client they did not do anything wrong. If the client is a user-operated web browser there is not much to do about it, but if the client is a library it tells the programmer that the error is not their fault (i.e. packets are not malformed nor data missing and so).

Good question, anyhow.

Esto hay que, entre otras cosas, publicitarlo por aquí. Y tengo que ponerlo en mi servidor. 🙂
