...nclude code that interfaces with the host system's OS, for example to use drawing and sound.
Considering the very slow performance of old video games (NES/SNES, etc.), emulation is quite easy on modern systems. In fact, it's even more amazing that you could just download a set of every SNES game ev...
Why does Python print unicode characters when the default encoding is ASCII?
...he same as case (4).
Conclusions:
- Python outputs non-unicode strings as raw data, without considering its default encoding. The terminal just happens to display them if its current encoding matches the data.
- Python outputs Unicode strings after encoding them using the scheme specified in sys.s...
Why is C so fast, and why aren't other languages as fast or faster? [closed]
...g portions of higher-level language code close to the performance level of raw C. But, for most applications, your program spends most of its time waiting on people or hardware, so the difference really does not matter.
Enjoy.

How do I get Windows to go as fast as Linux for compiling C++?
...0% of disk partitions is much faster than the rest of the disk in terms of raw transfer time. Narrower partitions also help minimize seek times.
Are you using RAID? If so, you may need to optimize your choice of RAID type (RAID-5 is bad for write-heavy operations like compiling)

Lossy compression, as its name implies, does not encode all the information of the file, so when it is recovered into an image, it will not ...

When to use LinkedList over ArrayList in Java?
...hough the CMS collector takes more resources and does not achieve the same raw throughput, it is a much better choice because it has more predictable and smaller latency.
ArrayList is only a better choice for performance if all you mean by performance is throughput and you can ignore latency. In m...
How do you convert a byte array to a hexadecimal string, and vice versa?
...u need to do these conversion, you tend to do them a lot. If someone needs raw speed, they just run the benchmarks with some appropriate test data in their desired computing environment. Then, tuck that method away into an extension method where you never look its implementation again (e.g., bytes.T...
Is it possible to print a variable's type in standard C++?
