ChaCha12-256 (without the usual security margin) has about the same #performance as AES-128 on several generations of Intel #hardware, because it’s good at #vectorization of #crypto, and will get faster now that Intel is exposing their 52-bit multipliers as #djb requested in 2002. Also apparently Intel is adding inversion in GF(256).
Amateur #sociology on why subcultures eventually died through inundation with poseurs until about 2000.
Meredith comments on #Appelbaum.
Simulating water ripples efficiently with integer #DSP time-space filtering: d[i] = ((s[i-1]+s[i+1]+s[i-320]+s[i+320]) >> 1) - d[i]; d[i] -= d[i] >> 5;. #graphics
#PDF of #Tandem tech report TR-89.3, explaining the programming API of the Transaction Monitoring Facility, which supports transactions distributed across requester and long-lived server processes.
#Arduino compatible #hardware with Freescale #ARM Cortex-M0s (MK20DX128 and MK20DX256) running at 48MHz or 72MHz, but it costs US$20
#Introduction to #GDB, or really the interfaces it uses, by Julia Evans
Zero-abstraction-cost #futures in #Rust since it no longer has “green threads”, with sequential composition, lifting functions, and AND and OR ("join" and "select") for them. Seems a lot like E promises. #concurrency
60 lawyers killed in a hospital bombing in Quetta, capital of Baluchistan, #Pakistan; credit for the attack is claimed by #Taliban and #Daesh.
Undercover FBI agent, whose identity remains secret, encouraged Elton Simpson to shoot up the Draw Muhammad event in Garland, #Texas, on 2015-05-03, where they wounded one security guard in the ankle and killed nobody. Does this qualify as #false-flag #terrorism?
