i'm trying find find relative merits of 2 small functions in c. 1 adds loop, 1 adds explicit variables. functions irrelevant themselves, i'd teach me how count cycles compare algorithms. f1 take 10 cycles, while f2 take 8. that's kind of reasoning do. no performance measurements (e.g. gprof experiments) @ point, old instruction counting. is there way this? there tools? documentation? i'm writing c, compiling gcc on x86 architecture. http://icl.cs.utk.edu/papi/ papi_get_real_cyc(3) - return total number of cycles since arbitrary starting point

i'm new coffeescript, looking forward writing javascript code in more akin ruby. what 2-3 resources can recommended tutorials or screencasts , running coffeescript? [ update : have book coming out pragprog, coffeescript: accelerated javascript development . also, latest version of coffeescript 1.1.0, though introduced few changes; mainly, it's bugfix release.] the official documentation @ http://coffeescript.org up-to-date place you're going find. right now, latest release of coffeescript 1.0.1. there lot of changes in 1.0. orbit linked 2 other resources nice dated. tongue-in-cheek 7 reasons gonna hate it presentation way when assignment done using : instead of = . nettuts+ tutorial written when latest release 0.9.6 and, think , doesn't touch on that's changed since (such classes). so, might want go through nettuts+ tutorial, official docs, start reading real-world source code. see http://github.com/jashkenas/coffee-script/wiki/in-the-wild ...

i’m creating web app school using asp.net , sql 2008. have page users view course descriptions. part of course description include list of topics covered. topics different every course , there different amount of topics every course. data bind topics ordered list in repeater. need provide search functionality on web app. elegant , normalized way of storing topics in sql? want avoid writing vb or using client side scripting. i’ve considered: •entering values separated commas in field named topics. don’t want have programmatically separate values repeater , i’m not sure if elegant solution db. •using xml data type field named topics. think may not necessary , more complex needs be. •creating separate table each course pk , field named topics. don’t want have create tables! not trying lazy efficient! when designing databases helps work core objects/entities , see how relate each other. try , have normalized tables, never de-normalize until need to. in above exam...

i've got bash script defines array of file globs containing * wildcards. the script executes python script passing each of these globs parameter. on command line can quote entire glob, , python happy it. in bash script, if quote globs, python's os.path.realpath seems confused quotes - passed in script itself. e.g. bash script: backup_paths=("/root/backups/db-dump-*" "/root/backups/*_backup.tar.bz2") path in "${backup_paths[@]}" /usr/local/bin/python2.7 /usr/local/bin/clean.py \'$path\' $max_files done python: os.path.realpath(path) # results in like: /usr/local/bin'/root/backups/db-dump-*' how can make them play together? thanks instead of \'$path\' , use "$path" . double-quotes allow contents of variable $path substituted, prevent wildcard expansion , ensure path passed single argument.

i'm using ttcatalog , creating ttbutton using following: ttbutton *button = [ttbutton buttonwithstyle:@"toolbarbutton:" title:@"click button"]; i tried adding target , action that, doesn't work. how use it? you missing "[". ttbutton *button = [ttbutton buttonwithstyle:@"toolbarbutton:" title:@"click button"]; [button setuserinteractionenabled:yes]; [button addtarget:self action:@selector(buttonpressed:event:) forcontrolevents:uicontroleventtouchupinside]; then set button properties, use target/action set event handler.

what difference between html.label , html.display ? html.label() renders html markup <label /> can used model entity's attrubute. for eg, <%= html.label("full name", model.fullname) %> would render <label for="fullname">full name </label> html.display() on other hand renders html markup entire entity based on specified templates. eg. if have person entity multiple attributes, define template markup how render person , html.display() uses template render person objects across views. phil haack has excellent post on display templates.

maybe fits in math.stackexchange.com, since programing in opengl, shall ask here. i had idea of spaceship game world confined in surface of 4-d hypersphere (also called 3-sphere). thus, in seeing inside, 3-d world, navigating in every direction, never leave limited volume of 3-sphere. to represent 3-shpere "flat" 3-d space, use stereographic projection, simple implement glsl shader, need divide input vector 1 minus w coordinate. to represent vertices of objects using normalized 4d vectors, such x²+y²+z²+w²=1, keeping them inside 3-sphere. the first problem solve rotation. figured out ordinary 3d rotation matrices suffice rotate world around viewer in 3d projection, since not mess w coordinate (pretty rotating sphere around z-axis rotate stereographic projection). then figured out rotating along w-axis equivalent of translation inside 3d projection (just not commutative, ordinary 3d translations on "flat" spaces), translate along axis using simple aroun...

i want run following on table of 12 million records. alter table t1 add c1 int null; alter table t2 add c2 bit not null default(0); i've done in staging , timing seemed fine, before in production, wanted know how locking works on table during new column creation (especially when default value specified). so, know? whole table locked, or rows locked 1 one during default value insertion? or different altogether happen? yes, lock table. a table, whole, has single schema (set of columns, associated types). so, at minimum , schema lock required update definition of table. try think how things work contrariwise - if each row updated individually, how parallel queries work (especially if involved new columns)? and default values useful during insert , ddl statements - if specify new default 10,000,000 rows, default value has applied of rows.

supposing have following public class foo { private map<integer,someobject> mymap; public foo() { this.mymap = new hashmap<integer,someobject>(); } private class runner implements runnable { public void run() { someobject someobj = new someobject(); foo.this.mymap.put(10,someobj); //'soobj' null upon retrieval later... } } } if create thread runnable of type 'runner' , start thread, run. in run method, create instance of 'someobject' , place in map of outer class. however, when attempt value 'mymap' later on, 'someobject' instance null. can't understand why have placed reference map 'mymap' still lives on in heap after thread finishes. there way around this?! thanks much it problem way objects instantiated. should be: foo foo = new foo(); thread thread = new thread(foo.new runner()); thread.start();

i working on c++ library split multiple namespaces. since trying avoid "using" directive in header files forced alternative "namespace::class" variables, returns , parameters. can imagine messy. so, tried putting using statement inside namespace decloration (see below) , seemed trick, doesn't appear visible in files including file. namespace project { namespace utility { class a; } namespace system { using utility::a; class b { *a; // instead of utility::a *a }; } } my question is, okay instead? // header namespace project { namespace utility { class a; } namespace system { using utility::a; class b { *a; // instead of utility::a *a }; } } // end header class {}; int main() { using namespace project::system; a; } test.cpp:25:5: error: reference 'a' ambiguous a; ^ test.cpp:20:7: note: candidate found name lookup 'a' class {}; ^ test.cpp:9:20...

i trying adjust position of fancybox jquery: $('#fancybox-wrap').css("top", "200px !important"); and wasn't working @ !important bit. if css, it's ok deal: #fancybox-wrap { top: 200px !important; } which leaves me curious: there inside fancybox' codes that's preventing me changing wrapper's css via javascript? the css function put styles in style attribute. navigators seem not allow usage of !important in inline style. inline style should overpass css rule if "important". so $('#fancybox-wrap').css("top", "200px"); should work?
