Right. Commercial "high purity" bromine is 99.5% purity, and easily available at reasonable cost. Semiconductor processes want 99.9999%. Merck offers that. [1] €2500/liter from a lab supply house. Very few companies offer the

At 4 bits, you could just have a hard-wired table lookup. Two 4 bit values in, 256 entry table. You can have saturating arithmetic and a post-processing function for free. Somebody must be building hardware like that.

This makes sense. The 1-bit model implies needing 2x as many neurons, because you need an extra level to invert. But the ternary model still has a sign, just really low resolution. (I've been reading the MMLU-Redux questions for electr

We're going to see much more of this. It's possible to get a lot done without actually knowing how to program now. Amusingly, this was with Unity, and didn't even involve AI. We're going to have a whole generation of dev

From the title, I thought this was going to be about customer support, or non-support. A good article about the costs of not listening to your customers would be useful.

No, there isn't likely to be a bromine shortage. The US is a major producer of bromine.[1] It's not at all rare. It's just that the cheapest source is the Dead Sea, because that's concentrated brine. There are bromine we

There were fourteen Nike sites in the Bay Area. We may see large numbers of local defense sites again, against drones and medium-range missiles. Israel and Iraq already have that.

Make sure that all your wall outlets in the area are actually grounded. Get an outlet tester at a hardware store and check. They cost about $10. Good first step. There are sometimes 3-prong outlets where the ground connection is not connect
