Java nowadays is mostly used for business applications, where developer productivity is more important than runtime performance. Java being memory safe is a huge part of that, whic…

While Google's support was definitely a factor, Go also had some important language features going for it. Most importantly it is targeting a relatively empty niche in the programm…

Rails was the first of that type of web framework. Django and all similar frameworks are Rails clones. At that time Rails was the killer app for Ruby. Unfortunately for Ruby the ot…

AFAIK the Google cache is just that: a cache. If a page is deleted, the cached version will also expire after some time. For permanent record, you need the wayback machine, but tha…

And since a filesystem is an ad hoc, informally-specified (or unspecified, how long did it take before linux could read ntfs?), slow (for some things: no indexes), bug-ridden (FAT …
