What science can tell us about C and C++'s security
There are not a lot of very strong empirical results in the field of programming languages . This is probably because there’s a huge amount of variables to control for, and most of the subjects available to researchers are CS undergraduates.

Subresource Integrity Addressable Caching

jQuery file size
Note: The gzipped and Zopflinated file sizes refer to the total byte size of the file after compressing it using gzip or Zopfli with the default settings .

How to C in 2016
