Optimizing DOM Memory Usage in Senc...
String, StringBuffer, and StringBuilder
...nce from a String may carry an unacceptable performance penalty, either in CPU time or memory (obtaining substrings is CPU efficient because the data is not copied, but this means a potentially much larger amount of data may remain allocated).
You use StringBuilder when you need to create a mutable ...
Efficient Algorithm for Bit Reversal (from MSB->LSB to LSB->MSB) in C
...ttention since it deals with a simple problem that requires a lot of work (CPU cycles) even for a modern CPU. And one day I also stood there with the same ¤#%"#" problem. I had to flip millions of bytes. However I know all my target systems are modern Intel-based so let's start optimizing to the ex...
How can I store my users' passwords safely?
...usually stored together with the password hash" any additional storage and CPU requirements for a per-user salt are so microscopic, that they need not even be mentioned...)

How does Go compile so quickly?
...sform the text into binary.
The Go compiler targets only a small number of CPU architectures, while the GCC compiler targets a large number of CPUs
Compilers which were designed with the goal of high compilation speed, such as Jikes, are fast. On a 2GHz CPU, Jikes can compile 20000+ lines of Java co...
Does anyone have benchmarks (code & results) comparing performance of Android apps written in Xamari
...droid nativly comes with multipe forms to execute code in:
RenderScript (CPU and GPU)
Java (SDK)
C++ (NDK)
OpenGL (GPU)
It is quite obvious that when executing code the more native the solution the faster it will be. A run-time based language will never beat a language that directly runs on the ...

Under what circumstances are linked lists useful?
...retty fast, because the array is filled sequentially (plays very nice with CPU cache).
Not to mention that a chaining hash table is expensive in terms of memory - and this "trick" cuts "pointer sizes" in half on x64.
Essentially, many linked lists are stored in an array. (one for each bucket used...
What are the pros and cons of performing calculations in sql vs. in your application

don't push the database to its CPU limits with complex, concurrent calculations (in favour of pulling data into application memory and performing calculations there)
In my experience, with a decent DBA and some decent knowledge about your decent database...
How are everyday machines programmed?
...have 8 or 16 pins on the chip - compared to scores of pins in your regular CPU socket.
So the workflow is write some code (say, in C), compile it on your desktop machine. That compiler generates machine code for the embedded chip. Then that code is loaded onto the microprocessor (and you need speci...
