Since the cpu always accesses a full cache line (64 bytes) at a time, you might as well search the entire cache line (it’s practically free once the data is on-cpu). So I’d like to try a ‘binary’ search that tests all the values in the ‘middle cache line’ and then chooses to go left or right if none match. You can do the cache line search as a single 512bit simd instruction. A cache line is 64 bytes (or 32 16-bit integers); such a search might well be almost 32 times faster than simple binary search; at least it’ll do 32x less memory accesses, which will dominate in most realistic programs.

In Denmark there are no payphones. Like none. The copper network is being decommissioned.

I’m surprised how many places in the world measure rain in percentage chance. Must be a metropolitan concept. Here in Denmark, weather reports estimate mm/hr - the amount of rain. Maybe it’s our agricultural inheritance?

Interesting. When you give a third-party access to your GitHub repositories, you also have to trust that the third-party implements all of GitHub’s security policies. This must be very hard to actually assume.

Unfortunately that’s the case because large US-based companies can leverage their existing global sales / marketing / governance setup to rationalize very high exit valuations. In the EU we don’t have the large software shops that can do that. So for an EU based startup - it’s exit to a US-based company or go all the way to an IPO / profitability.

Copenhagen’s sewage system was built in the 1850s and it was indeed considered to build a two-pronged solution. There was much resistance against this because it would eliminate a whole industry of “night men” (poop collectors), as well as people drying and trading it as fertilizer. So they build a single-pronged solution that was initially only allowed to be used for rain water.
