Indeed. Copper sulfate is persistent (it's copper!) and is often used not long before harvest. Meanwhile, glyphosate is used early before planting to kill off the weeds and so it's naturally degraded (to harmless CO2 and water) by

Top-of-the-line NMC cells have energy density around 250Wh/kg at the pack level. The newer solid-state batteries can reportedly increase this to 400Wh/kg. So a reasonable 75kWh battery pack is going to weigh around 300kg and in fu

Another fun happy iOS story: we were launching our app a year ago, with a self-imposed deadline. As usual, tons of bugs were being fixed in the last moment. And then our authentication stopped working on simulated iOS devices (while still w

I heard from several engineers several years ago that egress was metered because their network did not have enough switching capacity to make it truly unmetered at AWS scale. Looks like this might have been a part of the solution.

Yes, there are several other options. This is the first one that is not metered.

One interesting consequence of this is that it's now (for the first time!) possible to get unlimited AWS egress. It's not cheap, and it's limited to `us-east-1`, but it's at least _possible_ now via AWS Interconnect: ht

Congresspeople (or local legislators) do not have the expertise to evaluate the rules. Or even bandwidth. For example, the NEC is around 800 pages and is extremely technical. That's why these minutiae are delegated to agencies. But Con

Yeah, agreed. We need another word for that. Literally everybody in the industry is affected by this. Typically it goes like this: you make a good UI that users like and release your product. The product manager gets rightfully promoted and

Not really. 16-bit programs on x86 used 32-bit pointers (effectively 20-bit due to the segment mechanism). 8-bit microprocessors used 16-bit addresses.

Unless you want to create a thread in your zygote. Then it breaks down. Raw fork() is terrible. Instead we need a proper primitive to stop and make a snapshot of a process.
