The primary issue here is that it is expensive to move data between processing units, and having them share memory has all the common problems with race conditions and cache invalidation. So while we can continue to squeeze more onto a smal

RISC-V is a variable-length instruction ISA, where instructions are a multiple of 16-bits.

If you exclude AVX-512, the number is probably less than half that. And since Intel locked AVX-512 out of alder-lake processors, if you want a consume grade processor which supports it you would buy a Zen4 from AMD.

I think "do something simple" is going to get phased out and replaced by "do something useful" over time. Consider if you want to load a 64-bit immediate into a register under the current RISC-V spec. Takes so many instr

That's not what a middleman means. When you buy eggs from your local farmer, is your farmer a middleman between your dollars and the eggs? No. They're a seller and you are a buyer. With a usd/btc trade, you are either the sel

I put 6 hours of work into Bitcoin in 2011. That's now a year and a half's salary. Gutted that I didn't put my life savings into it back then, although I pretty much have now (~95% of my net worth).

Bitcoin was never advertised as an 'investment'. People who think of it as such should go and re-read the whitepaper until it clicks. Those who consider bitcoin a ponzi have a view of bitcoin given to them by people who never unde

Quad-precision floats will be widespread before applications that use >256TiB of memory are common. In that case, we can NaN-box the quad float and have up to 112 bits of pointer space to play with. Lets assume we double the number of po

A relational DB can store data however it wants, including columnar formats. The interface presented to the programmer (SQL) just abstracts away the details. ECS are more similar to the relational model than OOP is, and do not necessarily s

One of the main goals of ECS is to improve the use of the cache and reduce the amount of dereferencing. An alternative approach, which does not sacrifice the more common OOP style: https://www.doc.ic.ac.uk/%7Escd/Shapes

You can do dependency injection with dynamic binding. See another post in this thread: https://news.ycombinator.com/item?id=32085346 An approach to do it statically is with implicit parameters. Scala has them, for example.
