Sopel··on Page Table Memory Consumption
At least on windows zombie processes may use no memory but still keep >=32KiB page table. So in this [extreme case of an AMD iGPU driver bug](https://superuser.com/questions/1838566/how-to-identify-a-dr...) close to 100% of memory was used by page tables (or would if pushed far enough)
Sopel··on What algorithm did Windows XP use to choose your initial user picture?
yes, you would have to allocate space for up to 100 file paths, but the article says

> it’s more efficient because it reduces the amount of calls into the file system, which is where the bottleneck is

Upon reading it a few times I think the article is alluding to a crappy two-pass solution where you don't store a filename but instead an index into a directory, which is flawed anyway due to being racy.

Sopel··on Show HN: What if the speed of light was 5 km/h?
The cart is moving down faster than the light "bouncing" from the top of the cart towards your eyes. Whether the light can actually bounce this way I do not know. https://imgur.com/a/Aztdj4C
Sopel··on What algorithm did Windows XP use to choose your initial user picture?
I don't see how this is supposedly more efficient than the easier approach of listing all files and choosing a single random number in 1..n

AlphaZero does not exist, as far as modern computer chess is concerned

They could but it's pretty much meaningless. You're bound to find outliers in favor of either engine, and the landscape is pretty chaotic

don't care, it has all the right points
Sopel··on Further human + AI + proof assistant work on Knuth's "Claude Cycles" problem
chess is just a simple mathematical construct so that's not surprising

The ML techniques it uses are only about evaluation, but you were close

yes
