About a year and a half ago, I wrote about a $12 “Gongkai” cell phone (pictured above) that I stumbled across in the markets of Shenzhen, China. My most striking impression was that Chinese entrepreneurs had relatively unfettered access to cutting-edge technology, enabling start-ups to innovate while bootstrapping…

After all they have been working on Swift for the past 4 years and we have just learned about it last week. HFS+ is seriously old HFS+ was released in 1998, in the era of Mac OS…
Programmers trying to make crypto run fast often say things like "Why can't the CPU designer just add a 128-bit multiplication instruction?" Sometimes these questions turn into academic papers analyzing the cycle counts that would be obtained from various instruction-set extensions. What's missing from most of these…
