if you're celebrating people getting laid off from one of the very few companies that was consistently contributing to a fully open source product, because you think that css cascades are really that important, really take a long hard look at your priorities

Historically, we've focused a lot on the brutal actions of authoritarian regimes, and today is no different.
Using imagery online of the shooting by an ICE agent in Minneapolis, we’ve created an animated sequence which highlights the approximate positioning of officers and vehicles at the scene. The red dot represents the agent who fired the shots. Yellow dots are other agents who arrived at the scene.

we've actually priced in all the externalities of car ownership but instead of having car owners pay for asthma treatment and environmental cleanup, it's a money transfer from idiots to local cartels

what if zod or another parser introduced a way to parse into rich types? effect already has some of this: schema can serialize & deserialize a rich duration type instead of having some ambiguous integer which could me milliseconds.
could be cool?

Okay, folks. I’ve been asked by a lot of friends who aren’t following the AI discourse to sort of clarify what the main camps are arguing, how they approach the issues, etc. As a thoughtful observer, I’m happy to provide this orienting service. No questions or comments, please. Hope it helps!

all right i'll lose my mind over this but as someone who has actually read abundance (the book) in full, i can report that the book spends five paragraphs on ceqa and all of them are about the law being used by nimby groups and none of them are about the law being used by environmentalists
![Then, in 1972, came a case called Friends of Mammoth v. Board of Supervisors of Mono County. A developer had proposed to build six buildings’ worth of condominiums and shops and restaurants near Mammoth Lakes, one of California’s beloved ski resort areas. Friends of Mammoth, a homeowners’ association, sued to stop the build, arguing that it would strain water and sewage resources. The novelty of their argument was that they sued under CEQA. The legislation, as passed, held that government entities in California needed to produce environmental impact reports before embarking on major new projects. But the developer of the proposed Mammoth Lakes condos was not an arm of the California state, and this was not a public project. The argument of the Mammoth homeowners held that yes, actually, it was, because any development that required public permits to be built was inherently a public project.
Friends of Mammoth lost the case in the lower courts but appealed up to the state Supreme Court, which ruled in their favor in a 6-to-1 decision. CEQA, the court held, applies “not only [to] situations in which the government itself engages in construction, acquisition or other development, but also [in] those instances in which the state regulates private activity.”70 That meant it applied to, well, almost anything that anyone might try to build in the state of California. As a lobbyist for the Sierra Club put it, CEQA now covered “anybody engaged commercially in putting two sticks of wood together.”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:bxmukjuf2e6z6tvpmklbbern/bafkreifthk4imvte5d3oszzhmvzjxbsjukvicbytzdsludp3aatdi6g3ri@jpeg)

i had a databases class in college in which we were designing a users table and the professor guided us to use (firstname, lastname) as the primary key, and i asked what we'd do if there were two people with the same name, and they said to include the social security number, i think of this a lot
