Adventures of putting 16 GB of RAM in a motherboard that doesn’t support it
A while ago, I put 16 GB of RAM into one of my computers. The computer is using a Foxconn P55MX motherboard with a Core i5 750. It’s old and could probably be replaced, but it still works for what I need.

How to liberate a Chromebook
Google is about as open as a clam. Over the holidays, I found a Chromebook that Samsung had given me to evaluate about six years ago and which had been gathering dust ever since. Coincidentally, Laura’s sister Annie had just told me that she needed a laptop. Hmm… Well, there was no way I was going to give her a Google…

ARM and Intel have different performance characteristics: a case study
In my previous post, I reviewed a new fast random number generator called wyhash. I commented that I expected it to do well on x64 processors (Intel and AMD), but not so well on ARM processors. Let us review again wyhash: uint64_t wyhash64_x; uint64_t wyhash64() { wyhash64_x += 0x60bee2bee120fc15; __uint128_t tmp; tmp…

“It's done in hardware so it's cheap” (2012)
This is one of these things that look very obvious to me, to the point where it seems not worth discussing. However, I've heard the idea that "hardware magically makes things cheap" from several PhDs over the years. So apparently, if you aren't into hardware, it's not obvious at all.
