I've sent my first Rust RFC PR out for review! Take a look 🦀 Unnamed enum variants let you reserve discriminants as valid - very useful for FFI, serialization, and embedded. If you put `_ = ..` on an enum to reserve the rest of the discriminants, you can `as` cast from the backing integer! #rust

this is blowing up some so for some context: - this is because ultimateframedata.com got an email from Capcom telling them to take down hitboxes from SF6 and so all SF6 info is gone from the site - officially Capcom's problem is that they do not allow using "unauthorized methods" to obtain game data

The details are now public, as of two hours ago. bugzilla.mozilla.org/show_bug.cgi... The secret P-384 keys for these intermediate CAs are all zeros except the last 8 bits. All not-updated software can be MITM'ed now. IOT boxes that can't or don't update are now trivially MITM'able forever.

If you make HTTPS requests or have other TLS clients and care about MITM attacks, you need to update today. If you run Go: go get go@1.27.3 If you run Homebrew: brew update brew install ca-certificates If you run Linux, maybe stay off the internet for now.

Anthropic found the origin of the NIST elliptic curve seeds: they were generated with drand48()! No one was seriously worried, but this should put some FUD to rest, completing the NIST ECC rehabilitation arc… just in time to be retired in favor of PQ. Also, we raised $36 Ki for ISRG. Yay!

That was actually Google's policy circa 2009: if you had a problem with trans people using the gendered bathrooms, then you were invited to use the single stall gender neutral toilets yourself.

Look at the shabby state and increasingly authoritarian trajectory of the country and ask yourself if we can endure 2 more years of a lawless Trump administration wreaking havoc with no check from Congress, then vote accordingly. This is not the time for a protest vote or purity politics.

When I voted for Joe Biden in 2020 I told everyone who would listen that the Democrats had failed to make the primary about finding someone who could beat back the growing fascist threat. I said that while I was willing to vote to kick the can down the road a few years, that was all we were doing.

Two months ago I reported on Amy Acton’s anti-trans turn and fears Dems would go the way of Labour. Some mocked me for it. Now that list is up to 28 major dem elected officials and entire state governments.

Rather than cover the cost of gender affirming care for trans youth under medicaid, Colorado is voluntarily enacting the republican "taper and detransition" policy for youth on medicaid and dropping coverage. WTF.

If we want to regulate AI, why not start with a simple law forcing LLMs to use "Meesa" instead of "I"? Easy to build, easy to verify and deflates a hype while still allowing people to use chatbots (so no one can claim we are limiting anything)

I need to decide if 1KB means 1,000 bytes or 1,024 bytes in all of my software I was leaning 1,024 but it looks like macOS and Windows both define KB as 1,000 these days I want whatever people are most likely to understand (I do not think most people know what KiB or MiB means)

"do you want a code sent via text or via email?" idk both protocols have arbitrary transit delays and imperfect spam filters, so why don't you send the same code to both and we'll see which wins

As hospitals across the country cave to the Trump administration’s threats to cut federal funding and abandon trans youth, actor Elliot Page speaks out. In New York City, NYU Langone, Mount Sinai, and NewYork-Presbyterian abruptly ended care for trans kids in response to these threats.

State-level anti-discrimination is a worthless protection when the feds are the bigots Every one of those doctors that refuses to provide care is a coward rather than standing in solidarity with trans people. I frankly don't care what their independent legal counsel says: make them fight

Dude thinks he's appealing to "moderates" (really just a handful of right-wing podcasters) and can't stop printing out receipts that say "Gavin ain't got that dog in him." His veto may as well have been sent from another planet where Republicans don't instantly breach every supposed norm.

It is extremely, EXTREMELY, insensitive to descendants of the Holocaust to in any way downplay the seriousness of talking about people being "sent to camps", a statement that should not be normalized in any way at all. Ever. Because of all the people that died, Aaron.

this is an…unbelievable paragraph. yeah, what could be the difference between the court overturning a duly-passed and signed law and the court overturning an executive memo that violates the law?

Tom Scocca@tomscocca.bsky.social

The paragraph before seems equally detached from events—this would-be stumper of a question about the Court overturning executive orders is a lot less of a stumper when the executive orders keep violating laws passed by Congress!
