This is very, very big:

Those are some of the most significant people that have put WordPress where it is right now. And this is a huge step towards breaking the Monopoly held by one of the project cofounders.

And I still don't know how and what does it means, but the Linux foundation backing it up feels huge.

yo fedi, how are you today?

I'm trying to find the absolute best, well-argumented (!) takedown blogpost you've read lately.. preferably related to software development.

Unfortunately my boss is on the hype-train (random glory posts in slack) and I'd like to counter him just a wee bit. Bring it on ๐Ÿ˜

Boosting appreciated for reach :boost_anim_vanilla:

2. We also did learn something new from the podcast. Jamie Reed is leaning into the hyper-conservative family values stuff, she at one point says that trans and queer people are destroying the American family with queer theory. Azeen has to interrupt to tell her, "You have an Anarchist tattoo!"

Just a short post to put it out there that I am pretty much always looking for new clients for ops consulting and systems maintenance, on projects big and small.

More than 25 years of experience building and running internet-connected servers and networks of all shapes and sizes for happy clients, some of whom have been with the company for more than 15 years.

Need your server(s) maintained? Want to move out of the US cloud? Upgrades? Migrations? Let me know! ๐Ÿ˜„

Boosts welcome ๐Ÿ™๐Ÿป

@silverpill I have found what I think is probably a bug, in Mitra but one of virtually no consequence. I thought you would like to know even if you decide not to fix it

I have been playing with Writefreely and the user name is the same as that of my Mitra instance apart from with a different subdomain :

chris@mitra.northumbria.me
Chris@writefreely.northumbria.me

The post is flagged as mentioning me, even though it doesn't. I suspect this is something to do with matching the username and will effect hardly anyone and not be important for anyone who is effected.

Metric fanatics take note: computers are not metric. Bits, nybbles, bytes, words, blocks and sectors, packets, allocation units, whatever, are far closer to traditional units of measure, where things are based on doubling and halving and even (often power of two) multiples: ounces, cups, pints, quarts, gallons, etc.

Computers are wildly and fundamentally not metric. K, M, G, T, P, you can't square a circle.

"Imperial" is simply when the ruling despots declared some random craftsmen's units were more popular and favorited then declared as "imperial".

Units of measure were populist ideas, they came out of skilled folk performing skilled tasks, and the units arose from need., not decree.

When you join a guild, you learn and accept it's systems. You don't claim allegiance with the closest Despot and defend their side.

Skill involves working in the world, and the world is messy and subjective and filled with people and their annoying and wonderful ideas. Fuck this idea of everything thing uniform. I want moar chaos. We certainly have too much order right now.

More interesting progress trying to make suitable for very busy sites!

I realized that (both with and ) is a *major* bottleneck. With TLS enabled, I couldn't cross 3000 requests per second, with somewhat acceptable response times (most below 500ms). Disabling TLS, I could really see the impact of a queue as opposed to one protected by a . With the mutex, up to around 8000 req/s could be reached on the same hardware. And with a lockfree design, that quickly went beyond 10k req/s, but crashed. ๐Ÿ˜†

So I read some scientific papers ๐Ÿ™ˆ ... and redesigned a lot (*). And now it finally seems to work. My latest test reached a throughput of almost 25k req/s, with response times below 10ms for most requests! I really didn't expect to see *this* happen. ๐Ÿคฉ Maybe it could do even more, didn't try yet.

Open issue: Can I do something about TLS? There *must* be some way to make it perform at least a *bit* better...

(*) edit: Here's the design I finally used, with a much simplified "dequeue" because the queues in question are guaranteed to have only a single consumer: dl.acm.org/doi/10.1145/248052.

Throuput curve of my latest stress test of swad (with ramp-up and ramp-down phase)Response times in percentiles. 97% stay below 10ms!

Btw at this point I don't know if anyone is reading or checking what I post here, as I'm new and have no contacts in the music communities I used to be more active in who I know are in Mastodon too. So it'd be nice if anyone can confirm I'm not talking alone with myself ๐Ÿ˜… or if there's any advice about how to get introduced to people and stuff, since I'm a bit... lost, I guess haha.

โ€œGet it right, and we deliver better programsโ€”for less money and quickly. But if we keep getting it wrong, services will continue to worsen, costs will keep going up, and Canadians may start to lose faith that the government can do anything right. And they would be justified in that cynicism.โ€ From @justinlingJustin Ling๐Ÿ†’๏ธ: thewalrus.ca/ottawa-tech-strat

Common theme in most of the sessions I've been on has been the necessity to integrate truly "private" vs. "public" frames - completely separate - on fediverse, and have that usability be both obvious and from a UX/UI perspective unable to get it wrong.

This has been true in conversations about note-taking, collaborative wiki's, personal social networks, and on and on.

@lcamtuflcamtuf :verified: :verified: :verified: Is that ("pick a large even number, subtract one prime from it, and get another for free") true often enough to be useful?

I checked for a couple of small numbers and e.g., there are 550 primes under 4000, but only 130 of them yield a second prime when subtracted from 4000. (24%) At 40000 it's only 18% of the time.

How do I teach myself to care more about writing efficient code? Coming from math I am happy if it simply always works and if you can read it and know why. But I would like to set a better example for my students. Unlike the math profs who taught me.

Dead simple but more theoretical things like search optimization might be a place to start?
