This is several years old now, but it is an overview of a (failed) attempt to replace Linux's existing random implementation with Fortuna, an improved variant of the Yarrow algorithm used by FreeBSD, and a comparison with Linux's existing r

There's no reason mobile phones with GPS-only chipsets can't be sold in Russia -- they just get hit with ~25% import duties that phones with GLONASS-supporting chipsets don't have. I wouldn't be surprised at all if China does something simi

Such a thing doesn't exist. For one, neither Beidou nor Galileo are operational GNSSes, so there is no economic incentive to create receivers that work with those services. Also, the Chinese government only just today published Beidou's ICD

Many reasons (very incomplete list): - There is significantly less spectrum available for upstream channel use than downstream channel use. (Something like 37 MHz vs. 500-800 MHz.) This means cable operators have to be very frugal with

If you have a machine with a UTF-8 terminal and a recent-ish Perl (tested on Perl 5.10 + Mac OS X 10.6), you can play along at home by running: perl -e '$ |= 1; binmode(STDOUT, ":utf8"); while (1) { print chr(9585.5 + rand()); select(
