LinkedBlockingQueue vs ConcurrentLinkedQueue
... call poll(), wait a bit if you hadn't found anything, and then poll again etc... leading to delays when a new item comes in, and inefficiencies when it's empty (due to waking up unnecessarily from sleeps).
From the docs for BlockingQueue:
BlockingQueue implementations are designed to be used p...
Why are nested weights bad for performance? Alternatives?
...the same attributes as LinearLayout(orientation, weightSum, layout_weight, etc.) and doesn't show message - "nested weights have bad for performance"
Example:

What is the difference between _tmain() and main() in C++?
...o program Windows is to define UNICODE. And some other adjustments for C++ etc., before including <windows.h>. Then use the Unicode functions like CreateWindow (in general with no W needed at the end).

Why does string::compare return an int?
... modern hardware) an integer of the same size as the system bus and/or the cpu registers, what is called the machine word. Therefore int is usually passed along faster than smaller types, because it doesn't require alignment, masking and other operations.
The smaller types exist mainly to allow RAM...
How to articulate the difference between asynchronous and parallel programming?
...nimation can also be considered as an individual task. If we have multiple CPUs/Cores or multiple machines available, we can render multiple frames in parallel to speed up the overall workload.

How does Google's Page Speed lossless image compression work?
...fullest, e.g. PNG8+a instead of PNG24+a, optimized Huffman tables in JPEG, etc.
Photoshop doesn't really try hard to do that when saving images for the web, so it's not surprising that any tool beats it.
See

ImageAlpha (lossy) for smaller PNG files (high-level descrip...
How can I determine whether a 2D Point is within a Polygon?
...cannot fit into the GPU memory, this method is slower than doing it on the CPU. If it would have to be huge and your GPU supports modern shaders, you can still use the GPU by implementing the ray casting shown above as a GPU shader, which absolutely is possible. For a larger number of polygons or a ...
