how to measure #performance of virtual machines, including #LuaJIT and #V8; Laurie Tratt argues that current #VMs are slow in part because of Goodhart’s Law: people engineer their VMs to do well on their benchmarks, but the benchmarks are unrepresentative.
the GraalVM is licensed under GPLv2 with the classpath exception, just like the JVM #java #vms #licensing
#politics story about how the government of #Taiwan got a photo op with some US state legislators who passed resolutions in Taiwan’s favor; depressing to think it might have raised false hopes among Taiwan’s voters
Laurie Tratt explains how #Rust does traits, very similar to #Golang interfaces, but not duck-typed

Simon Tatham has written a really nice collection of puzzle #games of the class including Minesweeper, the 15-puzzle, peg solitaire, Master Mind, SameGame, and Sudoku, some 39 games in all, written in portable C, a bit over 100 KLOC of it.
Wanda Lenius claimed to have taken #chloroquine with her husband to prevent #covid because Trump said it was okay. He died. They supported the Democrats; now she’s being investigated for murder.
thoughts on computational #reproducibility and why it isn’t simple to achieve
the #covid study that found really high seroprevalence in Santa Clara county has been revised downward as of 2020-05-11; now they estimate 2.8% rather than 2.5–4.2%. Still seems too high to me.

Igor Troitski’s 1996 patent on laser damage imaging #bubblegrams says that typically in glass you can put your points 200–300μm apart inside the glass; this suggests a bit density on the order of 30 bits per cubic millimeter without using position (presence or absence of bubbles at predetermined lattice sites) or potentially an order of magnitude greater just using displacements
