C++ Coding Standards Part 0: Automated Code Analysis

Automated analysis is the main advantage to working with a modern statically typed compiled language like C++. Code analysis tools can inform us when we have implemented an operator overload with a non-canonical form, when we should have made a method const, or when the scope of a variable can be reduced.

Practical Cryptographic Release Branch Validation

One of the problems I've been thinking about recently is how to get reasonable cryptographic validation of release sources and artifacts without destroying usability. There are several randomly-assorted problems here:

SHA-1 is relatively easy to collide, and thus signed Git commits and tags are insufficient
Maintaining an auditable and relatively tamper-proof list of trusted signatures is hard
"Strong crypto" is generally (and accurately) equated with "not human usable"
