The perfect catch-22. Carrying a smartphone? It will be seized, searched and used against you. Not carrying a smartphone? This fact itself is used as evidence against you. This is something straight outta NKVD playbook, Beria would be proud.
Best system for calculators IMO. Especially if you need to add many numbers together (eg doing price calculations)—just enter all the numbers to the register, double-check for errors, then add together. Way less error prone than traditional calculators.
Blindsight by Peter Watts. It's the quintessential modern take on cosmic horror. First there is the "external" horror of a truly alien spaceship that is compared to a "crown of thorns" and "devil's baklava" with its strange inhabitants, and then there is the "internal" horror of musings about the nature and relationship between conciousness and intelligence. Then there is the transhuman main cast, including Jukka Sarasti the vampire and the AI of the ship Theseus. The sidequel Echopraxia is also great, expanding on the concepts and introduces concepts like human hivemind, militarized zombies and Portia-like alien intelligence.
Killing Star by Zebrowski and Pellegrino discusses the Dark Forest hypothesis with various subplots about scientific ambition gone wrong, personal loss, paranoia and religious zeal (some nutjobs cloned Jesus and Buddha, and the clones, after raising their eyebrow in amusement, went "Nah, we're outta here!"). The novel starts with 99.9% of humans and life on Earth wiped out in relativistic bombing, and then it gets worse. The attacking aliens and their technology is well thought out and the way they hunt down the last remnants of humanity is harrowing.
Leslie Fish is still writing music. Plus her old works from 1980-s (eg It's Sister Jenny's Turn to Throw the Bomb and Firestorm) are as relevant now as they were 40 years ago.
