Why were old games programmed in assembly when higher level languages existed? -

-

i noticed if not nes / atari, etc games coded in assembly, @ time, c, cobol, , fortran existed think make easier code right? why did choose assembly on these available higher level languages?

those games had 8-bit cpu chips , microscopic memories, like, 2kb. answer take on half ram.

compiled code out of question. on 8-bit cpu's "large" memories, "64k" (whee!) compiled code difficult use; not routinely seen until 16-bit microprocessors appeared.

also, potentially useful language c , had not yet taken on world. there few if c compilers 8-bit micros @ time.

but c wouldn't have helped much. games had horribly cheap hacks in them pretty required timing-specific instruction loops ... e.g., sprite's y-coordinate might depend on when (in video scan) control register written. (shudder...)

now there was nice interpreted-bytecode language around time or perhaps little bit later: ucsd pascal running on ucsd p-system. although i'm not big pascal fan, way ahead of else processors. wouldn't fit on game or run fast enough game play, though.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
