good day all, ive been wondering, google searching , goign greyer quicker thinking if possible mod rewrite change specific symbol grabs url else? i.e. if url www.website.com/foo-bar using rewriterule can hyphen become forward slash? <?php $foobar = "foo-bar"; ?> <a href="/<?php echo $foobar; ?>">foo-bar</a> .htacces code have.. rewriterule ^([^/]+)$ index.php?page=$1 [l] so mod rewrite make url display on addressbar www.website.com/foo/bar if possible? regards, dan. have @ this: http://forum.modrewrite.com/viewtopic.php?t=2799

simple thing: "convert" e.g. float double . there 3 ways known me: float v = 4.2f; double u = (double)v; double u = double(v); double u = static_cast<double>(v); double u(v); edit: thought fourth option! are these identical or there subtle differences? suggest use? note question related basic types int, char, float, ... not pointers, pods or classes. double u = (double)v; , double u = static_cast<double>(v); equivalent because both cases standard conversion used. double u = double(v); creates temporary double object (which can optimized away anyway) used initialize u . since temporaty created anyway, using 3 kinds of casts, yeah, it's same. from 3 static_cast should preferred. it's couple of characters more typing, in long run it's better because first of explicitly specify cast type , since casting suspicious, in vivid manner

afaik java stores dates in long variables milliseconds. consequently someday there no value (cause long has maximum) correspond time of instant. know when happen? it's easy enough find out: public class test { public static void main(string[] args) { system.out.println(new java.util.date(long.max_value)); } } gives output (on box): sun aug 17 07:12:55 gmt 292278994 you may need subtract bit long.max_value cope time zone overflowing range of long, give reasonable ballpark :)

why use binary semaphores when same functionality can achieved simple variable ? because semaphore isn't simple variable, it's larger construct that. specifically, counting semaphore (which binary semaphore is, effectively, count of 1), there's added capability of blocking process/thread tries increment semaphore above maximum value. semaphores have additional facility state changed "atomically", means underlying memory surrounded logic ensure cpu caches , such flushed, , when value changed, it's changed "everyone". particularly important on modern multi-core processors. the semaphore appropriate use when trying guard shared resource on use. binary semaphore perfect resources can used 1 process/thread @ time.

i had number of signal processing filter classes identical apart few constants defining filter characteristic, decided change these template class maintainability , extensibility. there performance , memory management reasons preferring template on constructor arguments in case; embedded system. consequently have template class of form: template <int size, int scale_multiplier, int scale_shift> class cboxcarfilter { public: // allow access size @ runtime. static const int filter_size = size ; ... } which explicitly instantiate thus, example: template class cboxcarfilter<8, 1, 3> the problem when need access filter_size member requires: cboxcarfilter<8, 1, 3>::filter_size which rather makes access filter_size redundant since must repeated in arguments. solution problem this: // create alias filter #define cspecialistboxcarfilter cboxcarfilter<8, 1, 3> template class cspecialistboxcarfilter ; then can access filter_size thus: ...
