Disappointingly superficial. New York City has huge issues building anything underground, and the coordination issues mentioned in passing here are a huge reason why. But all the most well resourced newspaper on earth can muster about its home city is "the street markings look like abstract art"?

Behind the Mysterious Symbols Spray-Painted on Our Streets (Gift Article)
All over New York’s sidewalks and sewers, colored markings hide in plain sight, telling construction crews where to dig and creating accidental art.

Really nice work by Celeste Barnaby and colleagues at #PLDI on active learning for program synthesis. Various synthesizers, including LLMs, can produce multiple candidate programs given an underspecified intent. This system figures out multiple choice questions to ask the user to disambiguate.
Slide screenshot. Title: "Choose, Don't Label: Multiple Choice Query Synthesis for Program Disambiguation". What is this paper about? A. An active learning framework using multiple choice queries. B. An approach for synthesizing informative and interpretable queries. C. A new tool called Socrates that improves accuracy and usability. D. All of the above (checked). QR code to Try Socrates

picked this back up and turned it into a tool that can estimate within 10% the compile cost of functions. Think of it like cargo llvm-lines that rolls up to functions in your crate

i've been enjoying my time using jj, but i have to say, i've never 'lost' so much work since starting with jj. the anonymous commits, optional descriptions and lack of locally tracking bookmarks means i end up with tons of "temporary" commits lost on my tree i can never find again.

I think it would be politically difficult to ban all these major social media platforms overnight, but X is one that should go now — not just over Grok and deepfakes, but also the way Elon Musk has leveraged it to push far-right politics. disconnect.blog/x-shows-why-...
While I may not think a total ban of US-based social media platforms (and TikTok) makes sense in the short term, that doesn’t mean I feel that way about X. We need to remember that the influence of X has long been exaggerated because it was where politicians and the media hung out, and that position has been even further eroded since Musk’s takeover. Given that it is actively enabling the creation of non-consensual deepfakes and child sexual abuse material, not to mention its broader amplification of right-wing narratives, the only real option in my mind is for people to leave, if not for governments to ban it, so that influence is eroded even further. Replacing X is a much less of an ordeal than finding an alternative to Facebook or Instagram.

Greenland is happening. Not a joke, not trolling, not a distraction. He has already made up his mind and nobody who matters in the inner circle will try to talk him out of it. Some of them want it precisely because it will destroy NATO. There are no adults in the room. They really mean to do it.

I’m howling.
Recently, Clifford "Buzz" Grambo decided to upgrade his electric scooter. The old one he had purchased online only reached 16 mph and wasn't cutting it anymore. He needed to go faster to keep up with the US Immigration and Customs Enforcement cars he chases around Baltimore. So, Grambo bought a Segway MAX G3, which features a 2,000-watt motor and can get up to 28 mph.
"The first time I caught up to them, I could tell that they already knew who I was," he told me when we first spoke on the phone in late October. "They had seen me before, so they thought they were just going to speed away. I was like, ha-ha bitches, I got a new scooter!"
