How to decide when to use Node.js?
...votes. There's no simple way to read one record at a time from a CSV file. Etc.
I love NodeJS, it is fast and wild and fun, but I am concerned it has little interest in provable-correctness. Let's hope we can eventually merge the best of both worlds. I am eager to see what will replace Node in t...
Undefined, unspecified and implementation-defined behavior
...many "things" are left
undefined, unspecified,
implementation-defined, etc. However,
that's easy to say and even to give
examples of, but hard to fix. It
should also be noted that it is not
all that difficult to avoid most of
the problems and produce portable
code.

Polymorphism in C++
...hosen at runtime based on config files, command line switches, UI settings etc.,
implementation varied at runtime, such as for a state machine pattern.
When there's not a clear driver for run-time polymorphism, compile-time options are often preferable. Consider:
the compile-what's-called aspec...
How does Java handle integer underflows and overflows and how would you check for it?
...r absolute value than the computer can actually represent in memory on its CPU. So underflow does not apply to Java Integers. @BalusC

How to sum up an array of integers in C#
...= arr.AsParallel().Sum(); a faster version that uses multiple cores of the CPU. To avoid System.OverflowException you can use long sum = arr.AsParallel().Sum(x => (long)x); For even faster versions that avoid overflow exception and support all integer data types and uses data parallel SIMD/SSE in...

AsyncTask threads never die
...xecution. How many will run at once is based on the number of cores of the CPU. AFAIK, the current algorithm is 2N+1 parallel threads, where N is the number of cores.

How much is the overhead of smart pointers compared to normal pointers in C++?
...plementation details and CPU architecture for write barriers, atomic locks etc. once listening you will never talk about this feature being cheap. If you just want a proof of the magnitude slower, skip the first 48 minutes and watch him running example code which runs upto 180 times slower (compiled...
Why is transposing a matrix of 512x512 much slower than transposing a matrix of 513x513?
...differ by a a multiple of 4096 have a false dependency on Intel SnB-family CPUs. (i.e. same offset within a page). This can reduce throughput when some of the operations are stores, esp. a mix of loads and stores.
