Is there a max array length limit in C++?
...ine this number, so I don't see how this metric can be relied upon beyond knowing your theoretical limits in a vacuum.

Virtual Memory Usage from Java under Linux, too much memory used
...te segment that contains global per-process data for the library (I don't know what the segment with no permissions is; I've only seen it on x64 Linux). The read-only portion of the library can be shared between all processes that use the library; for example, libc has 1.5M of virtual memory space t...

It's not a general case, and you are justified in your s...
What is the most ridiculous pessimization you've seen? [closed]
We all know that premature optimization is the root of all evil because it leads to unreadable/unmaintainable code. Even worse is pessimization, when someone implements an "optimization" because they think it will be faster, but it ends up being slower, as well as being buggy, unmaintainable, etc...
In C#, why is String a reference type that behaves like a value type?
...another string and thus, unlike a true value type, the compiler could not know beforehand how much space to allocate to store the string value. For instance, an Int32 is always 4 bytes, thus the compiler allocates 4 bytes any time you define a string variable. How much memory should the compiler all...
Need a simple explanation of the inject method
...2, 3, 4].inject(0) { |6, 4| 6 + 4 }
Step :5 [1, 2, 3, 4].inject(0) { |10, Now no elements left in the array, so it'll return 10 from this step| }
Here Bold-Italic values are elements fetch from array and the simply Bold values are the resultant values.
I hope that you understand the working of th...

Shortcut for creating single item list in C#

Of course, if you know you'll be adding a bunch of stuff later it may not be a good idea, but still worth mentioning once.
