Hit off-by-1 errors in timing related tests when upgrading to Elixir 1.19. Turns out DateTime.diff changed subtly, it used to drop microseconds (everything rounded to seconds), now keeps them. Our tests relied on old behavior without realizing it. Hopefully saves ppl some debug time! 😅 #ElixirLang

Things that are unreasonably hard when running systems at scale: counting stuff accurately

Love this.

I would like to see a new benchmark on how well different LLMs are able to diagnose issues raised by Dialyzer. #myelixirstatus #elixir

Malleable software: Restoring user agency in a world of locked-down apps The original promise of personal computing was a new kind of clay. Instead, we got appliances: built far away, sealed, unchangeable. In this essay, we envision malleable software: tools that users can...

Wat heeft Faber nou eigenlijk bereikt? Dagblad @trouw.nl: Enkel dat de bestempeling van kwetsbare mensen tot zondebokken voor alles, hun reducering tot cijfers en “gelukszoekers” en het illegale afpakken van mensenrechten nu als normaal beleid beschouwd worden. En niet meer als moreel schandaal.

This is incredible!

Schrijnende constatering.

🧠 Both AI optimists and pessimists are missing the point. The real conversation should be about how we build trustworthy systems—not about sentience or superintelligence. Let's focus on practical risks and benefits instead of sci-fi scenarios.

There is one place, however, where Musk, with the help of his minions, achieved his goals. He did indeed shred U.S.A.I.D. Though a rump operation is now operating inside the State Department, the administration says that it has terminated more than 80 percent of U.S.A.I.D. grants. Brooke Nichols, an associate professor of global health at Boston University, has estimated that these cuts have already resulted in about 300,000 deaths, most of them of children, and will most likely lead to significantly more by the end of the year. That is what Musk’s foray into politics accomplished.

Musk should be asked about this in every interview he does now and forever. To ignore it is a dereliction of duty.

i think it should be a bigger story that the president held a meeting with a foreign head of state where he ranted about the most gutter white supremacist propaganda you can find on the internet

Have you come across the “I got a dog so I could talk to other strangers with a dog” folks yet?

Thanks for coming to my TED talk.

And teams that do build around microservices seem way more likely to start hating each other and throwing things over the fence as a result of the API contracts.

For the most part to me it seems like microservices make more sense when you have teams that hate each other and only want to communicate via API contracts.

It’s entertaining to me that our Turn.io app is the most network distributed application I’ve ever been part of building while also the largest monolith. Thanks to #elixirlang microservices aren’t a tax worth paying or even make sense to consider from an architecture standpoint.

Current Slack status:

I can only imagine the bailout package they are drawing up for themselves.

As the saying goes, privatize the profits, and socialize the losses.

Reminds of growing up in countries where having the picture of the president or other persons of authority visibly present at your place of business or work was a requirement. Performative signs of loyalty just to keep afloat. 🚩

Go Julia!!! 🙌 🙌
