this question has answer here: how use decimal range() step value? 26 answers the documentation says range must behave implementation (for positive step ): def range(start, stop, step): x = start while true: if x >= stop: return yield x x += step it says arguments must integers. why that? isn't definition valid if step float? in case, esp. needing range function accepts float type step argument. there in python or need implement own? more specific: how translate c code directly python in nice way (i.e. not doing via while -loop manually): for(float x = 0; x < 10; x += 0.5f) { /* ... */ } you use numpy.arange . edit: docs prefer numpy.linspace . thanks @droogans noticing =)

is there true difference in performance between number, number(3) , number(10)? doesn't rdbms use 32 bits store value regardless, , limit length of data when looked @ string? a colleague debated was, example, more efficient use number(10) vs number/number(11), thinking n number of bytes rather length of data in characters. i'd agree limit column size if number of rows guaranteed not exceed 10^n or so, particular database limit number of rows literally "as many possible", e.g. 2^32 or ~4 billion, though we'd never reach amount. coming "lowest maximum" situation seems pointless , waste of time , thought using number without specifying length simpler , incur no penalties. correct? technically, don't define length, precision , scale. the same numeric value (eg 100, 4.3) takes same internal value irrespective of precision , scale defining column. the maximum value column can hold determined both precision , scale. can store value 100 i...

i have case branch represents new version in there refactored data layer, of bug fixes applied trunk. doing oppsite way since of documentation have encountered refer merging branch trunk. still keep version branch , bug fixes in sync, how can done easily? if there conflicts due fact version branch has many changes it's directory hierarchy , files. best practice in case? subversion knows scenario of "feature branch": http://svnbook.red-bean.com/en/1.1/ch04s04.html#svn-ch-4-sect-4.4.2 i think applies degree situation. idea there changes trunk branch later easier re-integrate trunk. experience subversion not run smoothly like. other systems git or mercurial supposedly better job this.

i'm thinking of best way design achievements system use on site. database structure can found @ best way tell 3 or more consecutive records missing , thread extension ideas developers. the problem have lots of talk badges/achievement systems on website -- it's talk , no code. where's actual code implemention examples? i propose here design hope people contribute , create design coding extensible achievement systems. i'm not saying best, far it, it's possible starting block. please feel free contribute ideas. my system design idea it seems general consensus create "event based system" -- whenever known event occurs post created, deleted, etc calls event class so.. $event->trigger('post_created', array('id' => 8)); the event class finds out badges "listening" event, requires file, , creates instance of class, so: require '/badges/' . $file; $badge = new $class; it calls default event passing d...

i want use entity framework , autogenerated classes in application. i'm not interested on: persistance ignorance testing i care 1 thing: keep application organized keep things simple i read domain drive design , i'm interested on because claim simplify complex applications. when read code real application example shocked complexity of approach. my idea use partial classes extend classes generated ef. ther try approach , can give me advice? so, if understand correctly, hoping use data access tool, entity framework in particular, implement application. it sounds not in fact interested in doing domain driven design project. i think that's fine position in. ddd incorporates ideas , patterns , tools useful outside of ddd. however, others, caution going half way down ddd road. true concept of domain model. once begin attempting implement true domain model, practically need rest of pieces of ddd in order make work you. find without piece...

i've got little problemo. in codeigniter controller i'm loading same view many times array. each view assigned value, in turn added $data array pass view. i'm having problems getting data out of $data array in master template view. here's how created array: $data['views'][$current_value][$counter] = $this->load->view('sub_view', $data, true);` this inside while loop cycles through $counter until i've got data need. finished array have views, have many current values, each have many counters. what code should use try , out of array in master view? i've tried many different methods! it's not playing ball. has got ideas. cheers! sparkles okay, i've fixed it. turns out quite simple mistake, turns out knowledge of multi-dimensional arrays in codeigniter not bad. byeee x

i send lot of data through jquerys getjson method, example of function is function dosomething(sid){ if(sid){ $.getjson("ajax/ajaxdosomething.php",{sid:""+sid+""}, function(data){ //alert(data); if(data.success == true){ $('#add_vote_div').html('vote received'); $('#list_data_div').html(data.html); } else{ $('#add_vote_div').html(data.message); } }); } }` the problem can @ source , see location of php file sending data to, therefore point browser there , append data url. checks on data make sure right data type, dont want users able go url @ all. i thought maybe put ajax files behind main document root work jquery can't link absolute paths like $.getjson("var/www/ajax/dosomething.php",{sid:""+sid+""} (main document root var/www/html/) if made $.postjson work better, doesn't exist, ...

i have in html page, element appears several times, , running same js. problem is, want specific function if first 1 run (his siblings never ran - yet). i need semaphore sync between them. unable know how declare variable , semaphore in way in js. there lots of approaches. you need put flag somewhere . in absense of else, can put on window , use name that's unlikely conflict else. then javascript quite straightforward: if (!window.myuniquenameflag) { window.myuniquenameflag = true; // processing } but again, putting things on window not ideal if can avoid it, although it's very common practice. (any function or variable declare @ global scope property of window .) if function declared @ global scope (and therefore occupying symbol), can avoid creating second symbol. instead of: function foo() { // ...your processing... } do this: var foo = (function() { var flag = flase; function foo() { if (!flag) { fla...

i'm using ajax request (using jquery) compile ziparchive in php. files have zipped 1 gb, tooks long time zip these files. due timeout think ajax request callbacks internal server error (500). when i'm compiling zip archive of 50 mb working, when became bigger doesn't work anymore. when execute page manually error occured too, has ziparchive function in php. does know how problem can occured , how solve it? php ini settings high (so not solution) thanks check apache's rlimitmem setting, bit php's memory_limit . also try different combinations doing ajax upload without zipping , zipping without upload. try different compression (e.g. gzip), if debug system.

as title describes - looking opengl es resources. lot of seeing beyond level of startup... looking resources build knowledge - starting off simple , working complex topics. any suggestions appreciated! good luck that... opengl documentation downright comical. have used gl es in 3 android projects far, , while it's quite easy once you've got hang of it, can't recommend particular online source. i invested in opengl superbible , worked through first 4 chapters or so, , knew enough projections , textures etc pick needed pretty quickly.
