is there way free memory used required gems? rails app grows in memory usage , use gems when need them , after free them up, if possible. thanks! the whole purpose of memory managed programming language (ruby) avoid developers having concern such issues. if memory become sticking point, you'll need profile memory using following tools ruby/ruby on rails memory leak detection although control on memory limited ensuring memory leaks avoided , overall architecture inline best practices. example imagemagick takes excessive memory, rather having images being converted rails mongrels/passengers, restricting conversion dedicated ruby services, avoid large memory footprint.

in php layer i'm receiving error codes strings ("not_found", "expired", etc). it's small list of possible strings, perhaps dozen. what's efficient way of dealing these? using switch-case against string constants stored in class, or should parse them numbers (or something) first? or php smart enough doesn't matter? you might want consider using constants? let's have class error , define error codes there this: class error { const not_found = 0; const expired = 1; // , forth } and can use them in code accessing them error::not_found , switch statement wouldn't need compare strings has plain ints without downgrading readability.

hi how design nested grids in extjs please provide samples(how use rowexpander in extjs gridpanel) try this: //create row expander. var expander = new ext.ux.grid.rowexpander({ tpl : new ext.template('<div id="myrow-{id}" ></div>') }); //define function called when row expanded. function expandedrow(obj, record, body, rowindex){ //absid parameter http request absence details. var absid = record.get('id'); var dynamicstore = //the new store nested grid. //use id give each grid unique identifier. id used in row expander tpl. //and in grid.render("id") method. var row = "myrow-" + record.get("id"); var id2 = "mygrid-" + record.get("id"); //create nested grid. var gridx = new ext.grid.gridpanel({ store: dynamicstore, striperows: true, columns: [ //columns ], height: 120, id...

i display yes/no in different languages according boolean variable. there generic way format according locale passed it? if there isn't, standard way format boolean besides boolvar ? resources.yes : resources.no . i'm guessing boolvar.tostring(iformatprovider) involved. assumption correct? the framework not provide (as far know). translating true/false yes/no not strike me more common other potential translations (such on/off , checked/unchecked , read-only/read-write or whatever). i imagine easiest way encapsulate behavior make extension method wraps construct suggest in question: public static class booleanextensions { public static string toyesnostring(this bool value) { return value ? resources.yes : resources.no; } } usage: bool somevalue = getsomevalue(); console.writeline(somevalue.toyesnostring());

i'm reasonably new web programming, , i'm still struggling grips fact server has terrible short term memory, forgetting what's on screen time see it. i'm trying create custom control allows edit data fields inside repeater. depending on format of fields (the elementformat property), either text box or drop down list should generated. inside markup of page have: <custom:editfieldcontrol id="editfieldcontrol" runat="server" elementid='<%#eval("id")%>' elementvalue='<%#eval("value")%>' elementformat='<%#eval("format")%>' visible="false" /> control code-behind looks this: public class editfieldcontrol : webcontrol { private textbox textbox; private dropdownlist dropdownlist; protected override void createchildcontrols() { switch (the format of field...

i hope today, query simple 1 searching open source ecommerce solution can extended own modules etc. after scouring google there loads of open source solutions , different websites recommend different solutions. i trust community of stack far more random websites on google, can please make recommendations on systems have used , how found them on overall. thanks in advance. for big application, take @ magento : it's robust solution, both community , entreprise version. another idea (that might lighter) might prestashop . might suggest oscommerce , it's old software -- , if had success years ago, doesn't anymore (i've never used myself, colleagues of mine have worked -- , have since switched magento) .

i'm trying create android application process camera frames in real time. start off with, want display grayscale version of camera sees. i've managed extract appropriate values byte array in onpreviewframe method. below snippet of code: byte[] pic; int pic_size; bitmap picframe; public void onpreviewframe(byte[] frame, camera c) { pic_size = mcamera.getparameters().getpreviewsize().height * mcamera.getparameters().getpreviewsize().width; pic = new byte[pic_size]; for(int = 0; < pic_size; i++) { pic[i] = frame[i]; } picframe = bitmapfactory.decodebytearray(pic, 0, pic_size); } the first [width*height] values of byte[] frame array luminance (greyscale) values. once i've extracted them, how display them on screen image? not 2d array well, how specify width , height? you can extensive guidance opencv4android sdk . available examples, tutorial 1 basic. 0 android camera but, in case, intensive image processing, slower accep...

is possible implement tail recursive version of quick sort algorithm (via continuation pattern)? , if is, how 1 implement it? normal (not optimized) version: let rec quicksort list = match list | [] -> [] | element::[] -> [element] | pivot::rest -> let ``elements smaller pivot``, ``elements larger or equal pivot``= rest |> list.partition(fun element -> element < pivot) quicksort ``elements smaller pivot`` @ [pivot] @ quicksort ``elements larger or equal pivot`` direct style: let rec quicksort list = match list | [] -> [] | [element] -> [element] | pivot::rest -> let left, right = list.partition (fun element -> element < pivot) rest in let sorted_left = quicksort left in let sorted_right = quicksort right in sorted_left @ [pivot] @ sorted_right my first, naive translation similar laurent's version, except indented bit weirdly make apparent ...

i developing iphone application use existing code published under lgpl. because of nature of apple’s app store application not open source , charge amount (either $0.99 or $1.99) in order cover expanses publishing in store. have studied lgpl , know allows use of code proprietary software if using library. however, code in question written in javascript need convert objective-c, believe make considered “derivative work” , guess requires must open-sourced (please correct me if wrong). question if translating library language makes “derivative work”, , if enough open-source library, or must entire application using published under lgpl well? i have sub-question. there exists previous version of library has been translated several languages, including objective-c. however, written while library released under gpl (which prohibits using in closed-source software). in mean time license changed lgpl (for original javascript version), affect translated versions or still pure gpl? ...
