Why does the order of the loops affect performance when iterating over a 2D array?
...ht?
No: because of caches. Data from your memory gets brought over to the CPU in little chunks (called 'cache lines'), typically 64 bytes. If you have 4-byte integers, that means you're geting 16 consecutive integers in a neat little bundle. It's actually fairly slow to fetch these chunks of memory...

Go to Matching Brace in Visual Studio?
Is there a way in Visual Studio 2008 to go from a closing brace to its opening brace? I've found a fair amount of stuff about highlighting the brace, but nothing about moving the cursor to it.

The OutputPath property is not set for this project
... In my case, building a proj file, the difference between any cpuand anycpu was the issue, but your post helped me see that.

Why would introducing useless MOV instructions speed up a tight loop in x86_64 assembly?
...ome work in that area. But we're talking a minimum of 5-10 minutes of 100% CPU to compile, and the resulting optimizations would probably be CPU core model and even core or microcode revision specific.

Time complexity of Euclid's Algorithm
...rations is linear in the number of input digits. For numbers that fit into cpu registers, it's reasonable to model the iterations as taking constant time and pretend that the total running time of the gcd is linear.
Of course, if you're dealing with big integers, you must account for the fact that ...
How efficient is locking an unlocked mutex? What is the cost of a mutex?
...bugging. Simple table:
Less locks means more contentions (slow syscalls, CPU stalls) and lesser parallelism
Less locks means less problems debugging multi-threading problems.
More locks means less contentions and higher parallelism
More locks means more chances of running into undebugable deadlock...
Purpose of memory alignment
...y subsystem throughput tightly bound to the execution unit throughput (aka cpu-bound); this is all reminiscent of how PIO mode was surpassed by DMA for many of the same reasons in hard drives.
The CPU always reads at its word size (4 bytes on a 32-bit processor), so when you do an unaligned address...
