What's a good rate limiting algorithm?
...ng, you definitely do not want to use time.clock(), which measures elapsed CPU time. CPU time can run much faster or much slower than "actual" time. You want to use time.time() instead, which measures wall time ("actual" time).

...p into your build/deployment scripts. The advantages are:
It requires no CPU for Apache to gzip the content when the file is requested.
The files are gzipped at the highest compression level (assuming gzip -9).
You're serving the file from a CDN.

Difference between static memory allocation and dynamic memory allocation
...ister' variables. As expected, register variables should be allocated on a CPU's register, but the decision is actually left to the compiler. You may not turn a register variable into a reference by using address-of.

Remember the hardware makes it all possible. Study the hardware. You won't regret it.

What are Transient and Volatile Modifiers?
...le variable will be read from the computer's main memory, and not from the CPU cache, and that every write to a volatile variable will be written to main memory, and not just to the CPU cache.
2) transient keyword cannot be used along with static keyword but volatile can be used along with static.

Is inline assembly language slower than native C++ code?
...ion scheduling, for example, is very hard to tune by hand) and modern CISC CPUs have very long pipelines too.
For some complex microcontrollers even system libraries are written in C instead of assembly because their compilers produce a better (and easy to maintain) final code.
