Why is processing a sorted array faster than processing an unsorted array?
...I'm thinking of situation of array that looks like: [1,2,3,4,5,...998,999,1000, 3, 10001, 10002] ? will this obscure 3 increase running time? Will it be as long as unsorted array?

Is async HttpClient from .Net 4.5 a bad choice for intensive load applications?
...estion, I recently created some new ones involving much fewer HTTP calls (5000 compared to 1 million previously) but on requests that took much longer to execute (500 milliseconds compared to around 1 millisecond previously). Both tester applications, the synchronously multithreaded one (based on Ht...
How does data binding work in AngularJS?
...onsidered as "instant".
Limited — You can't really show more than about 2000 pieces of information to a human on a single page. Anything more than that is really bad UI, and humans can't process this anyway.
So the real question is this: How many comparisons can you do on a browser in 50 ms? Th...

What do 'statically linked' and 'dynamically linked' mean?
...sn't know the memory address of printf. So the compiler just writes CALL 0x0000, and adds a note to the object file saying "must replace this 0x0000 with the memory location of printf".
Static linkage means that the linker program (the GNU one is called ld) adds printf's machine code directly to yo...
Algorithm to compare two images
...matches are known beforehand. If for example in your test data you have 1,000 images where 5% of them match, you now have a reasonably reliable benchmark. An algorithm that finds 10% positives is not as good as one that finds 4% of positives in our test data. However, one algorithm may find all t...
Tactics for using PHP in a high-load site

Microsecond timing in JavaScript
... It returns the number of microseconds in the fractional (e.g. a value of 1000.123 is 1 second and 123 microseconds).
now() is monotonically increasing. This is important as Date.getTime() can possibly jump forward or even backward on subsequent calls. Notably, if the OS's system time is updated (...
