...nce seen in the first method is likely because the result string must be reallocated 200 times, and memory allocations can be slow. After two iterations you have "testingtesting". After three iterations, that string is thrown away and memory with enough room for "testingtestingtesting" is allocate...

...oftware/rdfc/index-en.html RDFC is probably not the fastest, but it does allocate data blocks. The absolutely fastest would have to use lower level API to just obtain cluster chains and put them into MFT without writing data. Beware that there's no silver bullet here - if "creation" returns insta...

... tell you, so long as the program gives the same answers. It might allocate some temporary Objects on the stack. It may optimize some variables or method calls totally out of existence replacing them with constants. It might version methods or loops, i.e. compile two versions of a meth...

... form (or near source, a form in which keywords were represented by 1-byte tokens, and line #'s by 2-byte binary ints, but the rest was just ASCII). So in fact a 'goto' would take different amounts of time depending on how many source lines it had to search through looking for the matching destinati...

...oduce this is beyond the scope of this answer but the TL;DR is that secret_token.rb conflates configuration and code as well as being a security risk since the token is checked into source control history and the only system that needs to know the production secret token is the production infrastruc...

....h> char* concat(const char *s1, const char *s2) { char *result = malloc(strlen(s1) + strlen(s2) + 1); // +1 for the null-terminator // in real code you would check for errors in malloc here strcpy(result, s1); strcat(result, s2); return result; } This is not the fastest wa...

...in multithreaded applications, or is there a significant risk that smaller allocations in other threads fail because of it? … presumably only if your arrays were just small enough to be allocated, but left nothing for anyone else. – PJTraill Jun 11 '15 at 14:...

...er("") to set the delimiter to an empty string. This will cause next() to tokenize into strings that are exactly one character long. So then you can repeatedly call next().charAt(0) to iterate the characters. You can then set the delimiter to its original value and resume scanning in the normal w...

...ed in will not be modified. Once you create a string "foo", some memory is allocated to store the value "foo". This memory will not be altered. If you modify the string with, say, substr(1), a new string is created and a different part of memory is allocated which will store "oo". Now you have two s...

...E has spaces unless they are already escaped. You'll get one line with two tokens each and then [UP] for every two space-separated tokens in your variable and then a single line at the end with your line text minus the total length of your input string. So be careful, since this could lead to intere...
