linux kernel - Asynchronous Read/Writing with libraw1394 -

-

i'm trying 2 computers communicate each other on firewire. both of computers running ubuntu 9.10 , both have read/write access /dev/raw1394 node. i'm using firecontrol test sending read/write requests. if can work firecontrol, should able figure out how same in code.

on computer a, this:

computera $ ./commander
work now

no adapter specified!
got handle
current generation number (driver): 1
1 card(s) found
nodes on bus: 2, card name: ohci1394
using adapter 0
found: 2 nodes on bus, local id 1, irm 1
current generation number (adapter): 7

entering command mode
type 'help' more information!
command: w . 0 0 0xde
insufficient arguments operation!
command: w . 0 0 2 0xde
writing node 0, bus 1023, offset 000000000000 2 bytes:
00 de
write succeeded.
ack code: complete

since computer on node 1, send node 0. go computer b , read node 0 , this:

computerb $ ./commander

using adapter 0

current generation number (adapter): 9

entering command mode
type 'help' more information!
command: r . 0 0 1
reading node 0, bus 1023, offset 000000000000 1 bytes
read failed.
ack code: pending; response code: address error

i'm using same offset both of them. doing wrong , how supposed read/write from/to firewire nodes?

i have these same problems when try , use raw1394 in own code.

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...

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."
