What does “Auto packing the repository for optimum performance” mean?
... "If you let Git finish", and it can... fatal: Out of memory, malloc failed (tried to allocate 79610689 bytes) error: failed to run repack -- this is what I get for sticking our entire codebase into one git repo. Guess I'm going to kill apps and force repack "manually"

TCP: can two different sockets share a port?
...Most kernels (incl. linux) doesn't allow you a second bind() to an already allocated port. It weren't a really big patch to make this allowed.
Conceptionally, we should differentiate between socket and port. Sockets are bidirectional communication endpoints, i.e. "things" where we can send and rece...
scala vs java, performance and memory? [closed]
...
Well, Rex's solution preallocates the memory for the array, which will make the compiled code run faster (because with your approach, you let the JVM periodically reallocate your array as it grows). Even though there was more typing involved, perfor...
Choose File Dialog [closed]
... that the .setFileEndsWith() doesn't work at all, because the file list is allocated in the constructor. You need to change the constructor to accept multiple input and then change the line: "boolean endsWith = fileEndsWith != null ? filename.toLowerCase().endsWith(fileEndsWith) : true;" to properly...
What is the difference between `sorted(list)` vs `list.sort()`?
... that you busted a myth too quickly. The fact remains that sorted() has to allocate a new list object and copy the references; the rest of the code paths are identical. See if you can run the same tests with larger lists. Compare it with just creating copies of lists and see if you can replicate the...
Parallel.ForEach vs Task.Factory.StartNew
... to complete. Shivprasad's approach focuses more on object creation/memory allocation than on computing itself. I made a research calling the following method:
public static double SumRootN(int root)
{
double result = 0;
for (int i = 1; i < 10000000; i++)
{
result += ...
Why does the 260 character path length limit exist in Windows?
...tion used that defined value.
My structure is correctly defined, and only allocates 592 bytes total. That means that i am only able to receive a filename that is less than 260 characters. Windows promised me that if i wrote my application correctly, my application would continue to work in the futu...
Objective-C ARC: strong vs retain and weak vs assign
... don't point to it anymore"
in other words " I'am the owner, you cannot dealloc this before aim fine with that same as retain"
You use strong only if you need to retain the object.
By default all instance variables and local variables are strong pointers.
We generally use strong for UIViewControlle...
Setting variable to NULL after free
... int *nPtr=NULL;. Now, I would agree that this would be redundant, with a malloc following right in the next line. However, if there is code between the declaration and the first initialization, somebody might start using the variable even though it has no value yet. If you null-initialize, you get ...
Why not use Double or Float to represent currency?
...y don't call for a lot of math, the operations consist of adding things or allocating amounts to different buckets. Introducing floating point and rounding just complicates things.
