Be wary this may play havoc with your branch prediction.

Why is volatile needed in C?
...ut that requirement, it would be difficult to write code which generated a predictable sequence of reads.

Why do people still use primitive types in Java?
...bad design choices. Autoboxing is a complete failure, it's neither robust, predictable or portable. I really really wonder what they were thinking ... instead of fixing the dreaded primitive-object duality they managed to make it worse than in the first place.

Default implementation for Object.GetHashCode()
... good approach for generating a hash - it tends to lead to a lot of common/predictable collisions - for example if Prop1 = Prop2 = 3.

0.1 float is greater than 0.1 double. I expected it to be false [duplicate]
... than or less than 0.1, so without looking at the actual values, you can't predict whether the single precision or double precision approximation is greater.
Here's what the double precision value gets rounded to (using a Python interpreter):
>>> "%.55f" % 0.1
'0.1000000000000000055511151...
Smart pointers: who owns the object? [closed]
...id objects destruction, mostly), and that the life duration of objects are predictable (RAII is your friend, again).
In this model, raw pointers are freely circulating and mostly not dangerous (but if the developer is smart enough, he/she will use references instead whenever possible).
raw pointers...
How to check if a string “StartsWith” another string?
...rform the operation. Apart from that, modern javascript engines use branch prediction, so the test strings should be different in each iteration.

Can someone explain this 'double negative' trick? [duplicate]
...y would you bother? Because it makes functions like the one you show more predictable. If it didn't have the double negative in there, it might return undefined, a Function object, or something not entirely unlike a Function object. If the caller of this function does something weird with the ret...
Create array of regex matches
... @Liv, If your pattern tends to produce matches with a fairly predictable size, and depending on whether the pattern matches sparsely or densely (based on the the sum of the lengths of allMatches vs yourStringHere.length()), you can probably precompute a good size for allMatches. In my...
