i have read posts on website using drawinrect instead of cgcontext draw methods. still draws upside down? thought using drawinrect print right side coordinate system originating @ top left? -(void) drawimage:(uiimage*) image atx:(float) x andy:(float) y withwidth:(float) width andheight:(float) height oncontext:(cgcontextref) context{ uigraphicspushcontext(context); [image drawinrect:cgrectmake(x, size.height-y-height, width, height)]; uigraphicspopcontext(); } notice i'm doing size.height-y-height , if don't doesn't go expect (assuming drawinrect using topleft coordinate system). renders in correct spot above code still upside down. help!!!!!! update thanks answer below working method -(void) drawimage:(uiimage*) image atx:(float) x andy:(float) y withwidth:(float) width andheight:(float) height oncontext:(cgcontextref) context{ uigraphicspushcontext(context); cgcontextsavegstate(context); cgcontexttranslatectm(context, 0, size.height); cgcontextscalectm(c

firstly, i'm using django. django provides gzip middleware works fine. nginx provides gzip module. make more sense use nginx's gzip module because implemented purely in c, or there other performance considerations i'm missing. secondly, django doesn't gzip under 200 bytes. because gzipping expensive have value when compressing output smaller that? thirdly, api i'm building purely dynamic little caching. gzipping expensive enough make unpractical use in situation (vs situation cache gzipped output on webserver)? 1) imagine 1 gzip compression enough , nginx faster, although haven't benchmarked yet. gzipmiddleware utilizes few built-ins, might optimized, too. # http://www.xhaus.com/alan/python/httpcomp.html#gzip # used permission. def compress_string(s): import cstringio, gzip zbuf = cstringio.stringio() zfile = gzip.gzipfile(mode='wb', compresslevel=6, fileobj=zbuf) zfile.write(s) zfile.close() return zbuf.getval

people have found means make div scrollable on ios devices using css transforms. have issue iframes on ios safari, whereby if try , use css3 transforms scroll content in iframe, resulting content clipped rendered first on screen. works fine on android devices, , works on divs on ios, not iframes. appears bug in safari webkit implementation. i've tried increasing height of iframe larger content contained within, , ensured overflow enabled on iframe. has been able come workaround? i'm absolutely in-need of iframe remote content, last resort proxy content through server sided page, , inject javascript in order perform translate3d on child's body tag: seems work. images - after translate 3d (notice clipping) : sadly don't have answer you, general opinion seems to stay away iframes in ios safari; support buggy. second approach of using server side proxy remote content, assuming lock down trusted third party content. also aware of apparent width limit

class shape contains 2 methods drawcircle() , drawtriangle(). each function takes different set of arguments. @ present, invoke calling pde file directly. how pass these arguments html file directly if have control arguments being passed draw function? 1) example.html has (current version) <script src="processing-1.0.0.min.js"></script> <canvas data-processing-sources="example.pde"></canvas> 2) example.pde has class shape { void drawcircle(intx, int y, int radius) { ellipse(x, y, radius, radius); } void drawtriangle(int x1, int y1, int x2, int y2, int x3, int y3) { rect(x1, y1, x2, y2, x3, y3); } } shape shape = new shape(); shape.drawcircle(10, 40, 70); i looking in html file, can move functions separate file , call them different arguments draw different shapes (much similar how in java) a.html <script> shape shape = new sh

for example when filtering html file, if every line in kind of pattern: <a href="xxxxxx" style="xxxx"><i>some text</i></a> how can content of href , , how can text between <i> , </i> ? cat file | cut -f2 -d\" fyi: every other html/regexp post on stackoverflow explains why getting values html using other html parsing bad idea. may want read of those. this 1 example.

how close mysql persistent connection? what language using? php? persistent connects timeout if on non-interactive session based on wait_timeout variable in my.cnf. see http://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_wait_timeout if using php (just guessing here) take @ http://php.net/manual/en/function.mysql-pconnect.php , http://www.php.net/manual/en/features.persistent-connections.php there interesting discussions on use of persistent connections - http://www.mysqlperformanceblog.com/2006/11/12/are-php-persistent-connections-evil/

i want store array of 100 int elements in rows ie 1 row of 100 int datatypes.and every single element contains array of 100 objects.how in java or android. use collection, "list of list": list<list<yourtype>> matrix2d = new arraylist<list<yourtype>>(); this structure can store table 200 rows , 100 columns each element of type yourtype . otherwise - if size fixed , want store yourtype values, theres no need generics: int rows = 200; int columns = 200; yourtype[][] matrix2d = new yourtype[rows][columns];

i have python program spawns many threads, runs 4 @ time, , each performs expensive operation. pseudocode: for object in list: t = thread(target=process, args=(object)) # if fewer 4 threads running, t.start(). otherwise, add t queue but when program run, activity monitor in os x shows 1 of 4 logical cores @ 100% , others @ 0. can't force os i've never had pay attention performance in multi-threaded code before wondering if i'm missing or misunderstanding something. thanks. note in many cases (and virtually cases "expensive operation" calculation implemented in python), multiple threads not run concurrently due python's global interpreter lock (gil) . the gil interpreter-level lock. lock prevents execution of multiple threads @ once in python interpreter. each thread wants run must wait gil released other thread, means multi-threaded python application single threaded, right? yes. not exactly. sort of. cpy

i've editable unbounded datagridview. i'm changing value of new row programmatically. normally, when user types in field of new row, becomes dirty , new row inserted below it. but in case, when user comes in field of new row, i'm trapping function key , changing cell value programmatically. mygrid.currentcell.value = "xyz"; and doesn't insert new row below it. now work around tried on cellvaluechanged event handler. if (mygrid.newrowindex == e.rowindex) { mygrid.rows.insert(e.rowindex + 1, 1); } but throws error saying no row can inserted after uncommitted new row. . how tell mygrid i've made current row (which new row) dirty , there need of new row after it? i working on winforms datagridview. in case tried @isid solution, here aid in that, tried mygrid.notifycurrentcelldirty(true); mygrid.notifycurrentcelldirty(false); by making current cell dirty in not working, have commit cell also. in next command flaggi

here dynamic programming problem find maximum l(chess horse - 4 item) sum in given matrix (m x n) for example : 1 2 3 4 5 6 7 8 9 l : (1,2,3,6), (1,4,5,6), (1,2,5,8), (4,5,6,9) ... and biggest sum sum(l) = sum(7,8,9,6) = 30 what o(complexity) of optimal solution ? it looks problem (submatrix maximum sum) say items positive both positive , negative any ideas welcome! if l constant size (4 elements, say), compute sum on < n*m positions , find maximum one. repeat 8 different orientations have. that's o(nm) overall.

i hava linux server has 2g memory/ intel core 2 duo 2.4 ghz cpu, developing networking system. use libmemcached/memcache store , access packet info, want know how many requests libmemcached can handle in plain linux server ? thanks! there many things affect request rate (cpu speed, other hardware drivers, exact kernel version, request size, cache hit rate, etc ad infinitum). there's no such thing "plain linux server." since sounds you've got fixed hardware, best bet test hardware you've got, , see how performs under desired load.

it should not possible run multiple instances of application. therefore project source contains: createmutex (nil, false, pchar (id)); if (getlasterror = error_already_exists) halt; now want restart application programmatically. usual way be: appname := pchar(application.exename) ; shellexecute(handle,'open', appname, nil, nil, sw_shownormal) ; application.terminate; but won't work in case because of mutex. if release mutex before starting second instace won't work because shutdown takes time , 2 instance cannot run in parallel (because of common resources , other effects). is there way restart application such characteristics? (if possible without additional executable) thanks in advance. perhaps should think outside box. instead of futzing mutex / instance logic, create another executable waits app close starts again. added bonus, can later use mechanism to, example, update of main app's binaries. it's easier run elevated instead of
