Most of my knowledge about FPGAs come from ex-FPGA people, so take this with a grain of salt: First off, clock rates on an FPGA run at about a tenth that of CPUs, which means you need a 10× parallelism speedup just to break-even, which can

Tariffs done well could be a boon for a sector. But they are tricky to do well, and the current administration doesn't show the slightest hint of being capable of doing it well. You have to treat tariffs not as a moat to protect an i

This is a rather tediously long article. The summary as I see it: 1. OpenAI hemorrhages money (on the order of $10's of billions a year). 1a. A subargument that this hemorrhaging is rather fundamental--OpenAI isn't anywhere close

The idea of pure functional programming is that you can really go quite far if you think of your program as a pure function f(input) -> outputs with a messy impure thing that calls f and does the necessary I/O before/after that

I don't have much experience with writing a custom gcc backend, but my experience with LLVM is that its model ends up being a somewhat poor fit for smaller or weirder architectures. For example, LLVM has this annoying tendency to reall

It would get more expensive in the US, which means there's going to be less demand for it, which means the wholesale producer price is likely to fall due to oversupply.

Synthetic wine is the name for people who are trying to create wine from its chemical ingredients rather than from the natural process of fermentation. There was an article several years back about one of these groups trying to get regulato

The problem with this worldview is that it dramatically underestimates the harm of "natural" products compared to "artificial" products. You see, if it's fermented grape juice, it's "natural", and so

There are, in isolation, arguments that someone could give for these actions to levy a rational basis. But given that the administration's own statements are frequently inconsistent with its actions, the best explanation for this is al

This isn't short-term pain for long-term gain; it's short-term pain for long-term catastrophe. The tariffs aren't some carefully-devised scheme to work out how to reshore manufacturing to the US; they're a slapdash schem
