California is weaning itself off fossil gas, fast. Gas-fired electricity generation in California fell by 26% in the first half of 2026, as utility-scale solar, batteries and the new SunZia wind project feed power in via a dedicated transmission line. buff.ly/QWQoLPc #ShareGoodNewsToo

A cutaway view of a stone tower containing an elaborate water-powered medieval geared machine. Rising out of the machine is a rainbow-tinted, pixelated God with the robes, beard and all. To one side of this scene is a cluster of tiny people in Jesus-era robes, falling about themselves in religious ecstasy all over a stone staircase, atop of which stands a robed priest with his hands upraised. The background is a set of shining golden rays, emanating from pixel-God.

Meme of Calvin's dad from Calvin and Hobbes explaining concurrency primitives.

"Playing with threads? I'll show you something interesting. The two kinds of concurrency are green threads and coroutines. Erlang? green threads. Python? Coroutines; Javascript? Green threads. C++ and Rust? Coroutines. Despite being called goroutines, Go uses green threads."

Update: iddqd is now formally verified*! * with limitations that are fundamental to this kind of formal verification, making it a complement to the existing layers of validation For more, see: oxide.computer/blog/iddqd-u...
Update 2026-06-16: Since publication, we’ve used Soteria to verify that iddqd's no-duplicate-index invariant holds under arbitrarily adversarial Hash and Ord implementations. Soteria is similar to Kani in spirit, though with different internals that make it more compatible with iddqd. Soteria is implemented as a symbolic execution engine that lets you declare points of nondeterminism in your code. (For example, within iddqd, we represent an adversarial Hash or Ord return value as nondeterministic, since we want to model adversarially bad user code.) Then, it:

Compiles the Rust program into a form suitable for formal verification.
Interprets this form until it reaches a point of nondeterminism, treating each such point as a symbol rather than a concrete value.
Branches at each point where control flow depends on a symbol, validating that there is no UB and that the invariants specified by the program are upheld. A lot of the cleverness lies in how the possibility space is collapsed down to something manageable. For example, Soteria doesn’t have to enumerate every possible Hash value; rather, it only has to fork in places where control flow depends on the Hash value.

Here's the serious bit for anyone who'd rather skip the 4000 words of jokes
Because the truth is, tech doesn't have an image problem. It doesn't have a message problem. It has an intention problem. What's wrong with the axe murderer who broke into my house is not that he hasn't successfully persuaded me to buy into his narrative. What's wrong is that he's trying to kill me with an axe. Similarly, when you launch a product that's designed to put millions of people out of work, block access to sources of verifiable truth, replace human creativity with slop, and lower the barriers to every sort of atrocity, the problem isn't that you haven't told the public a good story about those things. The problem is that you are trying to do them. (
There are things in the world that are more important than money. The fact that you seem not to believe this, that you seem to think any motive beyond ruthless acquisitiveness is fake, dishonest, or childish, is the heart of your problem. Your attitude is not by any means unique to tech, but the
