How is Node.js inherently faster when it still relies on Threads internally?
...first of which (poor tuning) I believe is the real explanation for all the tests I've seen so far. ([edit], actually, the more I think about it, the more I'm wondering if the memory used by vast numbers of stacks might be significant here. The default stack sizes for modern threads tend to be pretty...
What is memory fragmentation?
...ures or unexpectedly causes the system to run low on memory (catch this in testing, for preference!).
The standard libraries are no worse than anything else that allocates memory, and standard containers all have an Alloc template parameter which you could use to fine-tune their allocation strategy ...
Using @property versus getters and setters
...re
whether the attribute is read-only or read-write. Properties fail this test
if the attribute writable.
There is no need for the user to define an extra variable underlying the function, so we don't need the __init__ or setattr in the code. The variable just exists by the fact we've created this...
Hibernate vs JPA vs JDO - pros and cons of each? [closed]

How to make my custom type to work with “range-based for loops”?
...null_sentinal_t) {
return false;
}
};
live example of this.
Minimal test code is:
struct cstring {
const char* ptr = 0;
const char* begin() const { return ptr?ptr:""; }// return empty string if we are null
null_sentinal_t end() const { return {}; }
};
cstring str{"abc"};

How does libuv compare to Boost/ASIO?
...ar-real-time applications. If hard numbers are desired, libuv's benchmark test may serve as a starting point.
Additionally, while profiling should be done to identify actual bottlenecks, be aware of memory allocations. For libuv, the memory allocation strategy is primarily limited to the allocato...
Is non-blocking I/O really faster than multi-threaded blocking I/O? How?
... writes must be of a size which is a multiple of the page size. I have not tested it, but it sounds like this could also affect write performance positively for buffered synchronous and asynchronous writes.
The steps 1 to 7 you describe give a good idea of how it works. On Windows the operating sys...
Why do people say there is modulo bias when using a random number generator?
...ng choice, the bugs it introduces are subtle and almost impossible to unit test. Compared to just using the proper tool (such as arc4random_uniform), that's extra work, not less work. Doing more work and getting a worse solution is terrible engineering, especially when doing it right every time is e...
When do you use Git rebase instead of Git merge?

@jpeskin That's not what I'm seeing. I just did a quick test to verify. Create a directory with a text file, init a new repo, add the file and commit. Checkout a new feature branch (checkout -b feature.) Change the text file, commit and repeat so that there are two new commits on ...
