FYI -- [Micro-aggression warning: undecidability lurks below.] Sheesh! Talk about heavy handed; Palo Alto could simply have bounded time and/or space for its Turing Machines. But NOoooh! they've prohibited *stacks* (no CF), and probably even finite state machines. I presume that this is another attack on encryption technology (it IS aimed at Palantir -- which occupies much of Palo Alto -- among other companies), but perhaps that is just paranoia. I believe that the zoning ban also applies to macros -- code-producing code -- and compilers. Perhaps it's time to resurrect Google's Ark -- Google's plan to station a floating high-tech development platform off-shore to get around H1B visa hiring restrictions. http://www.siliconbeat.com/2016/08/31/no-coding-palo-alto-city-takes-silicon... No coding in Palo Alto? The birthplace of Hewlett Packard and Xerox Parc and founding place of Facebook is now considering whether to enforce a zoning regulation banning firms whose "primary business is research and development, including software coding," according to the New York Times. Palo Alto Mayor Patrick Burt told the Times: "Big tech companies are choking off the downtown. ItÂ’s not healthy." "For many of the 66,000 residents of Palo Alto, all this coding and innovation may be a bit too much." "But Palo Alto may not want the jobs either. Making coding off-limits in certain sections, however that is enforced, sends that message." http://www.nytimes.com/2016/08/30/us/spotty-cell-reception-in-the-heart-of-s... "the mayor [of Palo Alto] is looking to enforce, in some form, an all-but-forgotten zoning regulation that bans companies whose primary business is research and development, including software coding."
