say have list this hello1 hello2 hello3 hello4 goodbye hello6 hello7 hello8 how can remove goodbye , print everything else besides goodbye? use unset , array_search this: $array = array('hello1','hello2','hello3','hello4','goodbye','hello6','hello7','hello8'); if(($key = array_search('goodbye', $array)) !== false) unset($array[$key]); this 2 things in 1 if statement: if assigned value of $key (the return value of array_search ) truthy, proceed , use index, otherwise, don't anything. necessary because if return value of array_search false , resulting $array[false] not intended behavior @ all.

greetings by using pymssql library, want write data mssql database encounter encoding issues. here sample code write db: # -*- coding: utf-8 -*- import _mssql .... connection info data here .... def mssql_connect(): return _mssql.connect(server=host, user=username, password=pass, database=db, charset="utf-8") con = mssql_connect() insert_ex_sql = "insert mydatabsae (id, programname, programdetail) values (1, 'test characters ÜŞiçÇÖö', 'löşüiiğĞü');" con.execute_non_query(insert_ex_sql) con.close() sadly data written db corrupted: the collacation of mssql db is: turkish_ci_as how can solved? here possible solution : the key insert_ex_sq.encode('your language encoder') . try instead: con.execute_non_query(insert_ex_sq.encode('your language encoder'))

i idea of using compressed folders containers file formats. used libreoffice or dia. if want define special purpose file format, can define folder , file structure , zip root folder , have single file data in single file. imported files live originals inside compressed file. defining binary file format 0 features lot of work. now question: there applications using compressed folders file formats , versioning inside folder? benefits great. commit state in project file , versioning decorated functions own application. diffs presented own way. libraries working compressed files , versioning available. used versioning system should distributed system, repository lives inside working folder , not seperate example subversion client-server model. what think? i'm sure there applications out there using approach, couldn't find one. or there major drawback in approach? sounds interesting idea. know many applications claim have "unlimited" undo , redo, that...

hi i'm trying using vlc broadcast udp stream within lan, making tv channel. i used command line launch vlc vlc ok run = cvlc --repeat filename.avi --sout '#standard{access=udp,mux=ts,dst=239.255.12.42:8001} problem works on network, , have problem receiving on network without router! question: magical address "239.255.x.x" ? network hardware require udp broadcast besides switches , cables? wireless can accept udp broadcast? thanks answers! the 239.255.x.x addresses part of multicast address space, ranging 224.0.0.0 239.255.255.255 (and there specific-use areas in there). you've correctly noted doesn't work without router. because basic ip stack still wants know how route addresses determine interface send them on. can either add static route multicast (that address or multicast addresses), or put in default gateway.

what regex find text#2? pattern it's first occurance of "z=" after c. text want rest of line after z=. i'm using regex in .net a x b x z=text#1 x c x z=text#2 .*c.*z=([^\n]*).* you'll need turn on . matching newlines ( regexoptions.singleline below). here's c# code generated my regex tester : using system; using system.text.regularexpressions; namespace myapp { class class1 { static void main(string[] args) { string sourcestring = "source string match pattern"; regex re = new regex(@".*c.*z=([^\n]*).*",regexoptions.singleline); matchcollection mc = re.matches(sourcestring); int midx=0; foreach (match m in mc) { (int gidx = 0; gidx < m.groups.count; gidx++) { console.writeline("[{0}][{1}] = {2}", midx, re.getgroupnames()[gidx], m.groups[gidx].value); } ...

so have object getting rotated translated , rotated again. storing matrix of these translations object member. when come object picking need know 3d world coords of object. currently have been able position of object so coords[0] = finalmatrix[12]; coords[1] = finalmatrix[13]; coords[2] = finalmatrix[14]; this giving me correct positions of objects want take rotations account well. any great... the matrix 4x4 matrix, you've got single dimensional matrix appears elements arranged follows: [0] [4] [8] [12] [1] [5] [9] [13] [2] [6] [10] [14] [3] [7] [11] [15] the rotation part top left 3x3 matrix see here , in case elements [0]-[2] , [4]-[6] , [8]-[10]

when start tomcat server console using startup.bat script, new command window opens filled java logging statements. i use console2 leverages tabs each open console window. possible let java system create new tab within console2 instead of opening new command window? this has nothing java, merely down way catalina.bat called startup.bat catalina.bat can called either "start" argument or "run" argument. run start catalina in current window start start catalina in separate window so open startup.bat, scroll bottom should see "%executable%" start %cmd_line_args% change "%executable%" run %cmd_line_args% exit i add exit after close calling window.

what build system (make, extutils::makemaker , module::build , ...) use in perl subsystem (e.g. perl bindings, or auxillary command implemented in perl), , how connect build system of main project. project uses make build system. perl subsystem in separate subdirectory. we can assume if there perl installed, @ least version 5.8.3. for 5.8 eumm okay. connect main makefile straight-forward way, write perl-binding target contains usual incantation .

if have 2 mysql_query commands in single php file, way combine them? for example, have: $a=mysql_query(select * table1); $b=mysql_query(select id table3); but want combine them single mysql_query, more efficient? faster? multiple queries not supported in mysql_query descripted on php manual , can't combine both query in php mysql_query way here reference php manual notes : executed multiple queries @ once, mysql_query function return result first query. other queries executed well, won't have result them.

someone said utf8 has variable length encoding 1 3 bytes. so why still use latin1? if same thing stored in utf8 1 byte, utf8 has advantage can adapt larger character set. is hidden reason uses latin1? what disadvantages of using utf8 vs. latin1? iso 8859-1 (at least de facto) default character encoding of multiple standards http (at least textual contents): when no explicit charset parameter provided sender, media subtypes of "text" type defined have default charset value of "iso-8859-1" when received via http. data in character sets other "iso-8859-1" or subsets must labeled appropriate charset value. the reason iso 8859-1 chosen it’s superset of us-ascii fundamental character set internet based technologies. , world wide web invented , developed @ cern in geneva, switzerland, might reason choose characters of western european languages 128 remaining characters. when unicode standard developed, character set of iso 8859-1 ...

how increment nsnumber? i.e. mynsnumber++ update: fyi, boltclock's , darkdusts's one-line answers better. they're more concise, , don't require additional variables. in order increment nsnumber , you're going have value, increment that, , store in new nsnumber . for instance, nsnumber holding integer: nsnumber *number = [nsnumber numberwithint:...]; int value = [number intvalue]; number = [nsnumber numberwithint:value + 1]; or nsnumber holding floating-point number: nsnumber *number = [nsnumber numberwithdouble:...]; double value = [number doublevalue]; number = [nsnumber numberwithdouble:value + 1.0];

i had argument today 1 of collegues regarding fact compiler change semantics of program when agressive optimizations enabled. my collegue states when optimizations enabled, compiler might change order of instructions. that: function foo(int a, int b) { if (a > 5) { if (b < 6) { // } } } might changed to: function foo(int a, int b) { if (b < 6) { if (a > 5) { // } } } of course, in case, doesn't change program general behavior , isn't really important. from understanding, believe 2 if (condition) belong 2 different sequence points , compiler can't change order, if changing keep same general behavior. so, dear users, truth regarding ? if compiler can verify there no observable difference between two, free make such optimizations. sequence points conceptual thing: compiler has generate code such behaves as if semantic rules sequence points followed. generated code doesn't have f...

what fastest way this: var firstarray = enumerable.range(1, 10).toarray(); // 1,2,3,4,5,6,7,8,9,10 var secondarray = enumerable.range(9, 3).toarray(); // 9,10,11,12 var thirdarray = enumerable.range(2, 3).toarray(); // 2,3,4,5 //add these arrays expected output 1,2,3,4,5,6,7,8,9,10,11,12 is there linq way this. quite have huge list of array iterate. example var firstarray = enumerable.range(1, 10).toarray(); // 1,2,3,4,5,6,7,8,9,10 var secondarray = enumerable.range(12, 1).toarray(); // 12,13 //add these arrays expected output 1,2,3,4,5,6,7,8,9,10,12,13 note: prefer function work on date ranges. .union give distinct combination of various sequences. note: if working custom type, need provide overrides gethashcode/equals inside class or provide iequalitycomparer<t> type in overload. bcl types such int or datetime , fine. example: var sequence = enumerable.range(0,10).union(enumerable.range(5,...

i have following.. <span class="error">@model.errormessage</span> the problem css error class makes yellow box showing when errormessage empty. is there best practice handling this? thinking of @if (using razor) seems odd have logic in view. it seems odd have logic in view. view have view logic in it. mvc not mvp or mvvm code behind discouraged. believe having if in view quite normal. alternative have model (view model) have property set css class of span . if error empty, css class have display:none;

what's best way let ipad user browse documents folder, documents displayed grid of icons captions? (like events view in iphoto , files , folders in place of events.) there no built-in control sort of ui. either use aqgridview (on github) or build own subclassing uiscrollview.

i need tool scan c++ project see if there includes not being referenced or being referenced redundantly. thanks. you don't want this. want include header declares/defines used cpp file you're writing. if remove "redundant" headers included you're including when minor changes you'll editing files on damn place. use proper header guards make sure don't break one-definition rule.

i'm gathering basic metadata images - dimensions, although it'd nice other available metadata well. image formats i'm interested in png, jpg, , gif. i'm using pil @ moment, occurred me there may simpler way doesn't involve external dependencies or binary libraries. there one? answer: no there not simpler way using external library. if going care 1 , 1 file format only, yes. it's easy implement specific that. if want generic, need support lot of file formats, , don't want work yourself. to simplify install of pil, might @ pillow, friendly fork§ makes pil easy_installable.

take @ following image - see clouds in background have annoying seam: http://simoneschbach.com/seam.png this seam occurring when wrap around occurs, supplying texture coordinates programmatically following code: gbackgroundpos += 0.0003f; // gbackgroundpos climbs indefinitely... glfloat bgcoords[] = { gbackgroundpos, 1.0, gbackgroundpos + 0.5f, 1.0, gbackgroundpos, 0.0, gbackgroundpos + 0.5f, 0.0 }; i have enabled texture wrapping during texture init follows: gltexparameteri(gl_texture_2d, gl_texture_wrap_s, gl_repeat); gltexparameteri(gl_texture_2d, gl_texture_wrap_t, gl_repeat); does know can here rid of visible seam? the problem have solved technique, extremely simple implement: http://vcg.isti.cnr.it/~tarini/no-seams/ there open-source demo @ link, exposes used fragment shader. the trick easy adopt without complete understanding of why works, explained in journal of graphic tools article: "cylindrical ,...

disclaimer: know how classes loaded in jvm , how , when unloaded. question not current behaviour, question is, why jvm not support "forced" class/classloader unloading? it have following semantics: when classloader "forced unloaded", classes loaded marked "unloaded", meaning no new instances created (an exception thrown, "classunloadedexception"). then, instances of such unloaded classes marked "unloaded" too, every access them throw instanceunloadedexception (just nullpointerexception). implementation: think, done during garbage collection. example, compacting collector moves live objects anyway, can check if class of current object "unloaded" , instead of moving object change reference guarded page of memory (accessing throw abovementioned instanceunloadedexception). make object garbage, too. or done during "mark" phase of gc. anyway, think technically possible, little overhead when no "unloading...

short answer: yes, fullscreenevent temporarily adds 1 child stage. long rant: how that.. i'm not crazy.. don't know if documented - it's true. little message pops saying 'you can press esc exit full-screen' adds single child stage temporarily , keeps on top level until fades out. sudden intrusion of indexes messed me up.. there's answer, guess. need figure out how around slight annoyance. searching phantom child: tried find child, suggested, in project using stage.getchildat(11)+" "+stage.getchildat(10)+ ..etc etc.. , stage.getchildat(11).name+" "+stage.getchildat(10).name+ ..etc etc..(a quick sloppy way trace text box on stage..) couldn't tie specific name.. name came 'instance(whatever number in line created was)'. type interesting though because null .. don't know if that's normal or anything, if 1 of things had made, [object sprite] or similar.. odd indeed. furthermore, when trying information adobe live...

i in process of creating ui configuration tool pet project. 1 aspect of tool lets end user define orchestration. need save orchestration definition database. there executable version of definition in running system. executable version created dynamically on-demand. idea separate definition executable version have flexibility choose runtime version among bpmn or jpdl or pojo based workflow solution (beanflow). limitation : can't use bpmn editors come frameworks jbpm, activiti etc wan't use own ui specific domain. i need suggestions on how persist definition. should use rdbms tables? if so, there db schema can borrow close orchestration concepts? should serialize definition bpmn/jpdl xml instance document? are there other simple formats can use? by "orchestration" i'm assuming mean finite state machine . current state dictates transitions can followed other states. representation of states , transitions edges , vertices produces directed a...
