Why doesn't JavaScript support multithreading?
...he internal mechanism (aka callback/promise/async-await)
if you need to do CPU bound ops, then use worker threads.
Worker threads are intended to be long-living threads, meaning you spawn a background thread and then you communicate with it via message passing.
Otherwise, if you need to execute a...
What are the differences between a UIView and a CALayer?
...ore. Working with UIViews happens on the main thread, it means it is using CPU power.
CALayer: Layers on other hand have simpler hierarchy. That means they are faster to resolve and quicker to draw on the screen. There is no responder chain overhead unlike with views. Layers are drawn directly on t...

Context switching is when a CPU stops processing on one thread and starts processing on another. I.E. the CPU switched it's context from one thread to another. This happens constantly in PCs, it gave us the illusion of multitasking before there were m...
Python 3.x rounding behavior
...
I saw that. And my first reaction: Who is using a 16-bit CPU that is incapable of representing all permutations of "2.67x" ? Saying that fractions can't be expressed in float seems like a scapegoat here: no modern CPU is that inaccurate, in ANY langauge (except Python?)

Spark java.lang.OutOfMemoryError: Java heap space
...uch mem you're using)
Try using more partitions, you should have 2 - 4 per CPU. IME increasing the number of partitions is often the easiest way to make a program more stable (and often faster). For huge amounts of data you may need way more than 4 per CPU, I've had to use 8000 partitions in some c...
Why are C character literals ints instead of chars?
...A' from this main memory into a register, which one would you read?
Some CPUs may only directly support reading a 16 bit value into a 16 bit register, which would mean a read at 20 or 22 would then require the bits from 'X' be cleared out, and depending on the endianness of the CPU one or other wo...
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 ...
How to free memory in Java?
...new in the last six years) G1 collector is a low-pause model; it uses more CPU overall, but does it's best to never force a hard-stop on execution. Since server CPUs now almost all have multiple cores, this is A Really Good Tradeoff to have available.
Look at your flags tuning memory use. Especial...
