what trying do: my bash shell script contains modprobe -a $modulename . loading module fails , modprobe statement gets stuck. never returns , hence, script stuck too. what want this: call modprobe -a $modulename , wait 20 secs , if command not return , script remains stuck 20 secs, call failure , exit ! i looking @ possible options that. know timeout one, allow me timeout after time. thinking : timeout -t 10 modprobe -a $modulename if [ "$?" -gt 0 ]; then echo "error" exit fi but problem $? can > 0 , not because of timeout, because of error while loading module , want handle 2 cases differently. any ideas using timeout , without using timeout welcome. according timeout(1), timeout exits specific code (124 in case) if command times out. it's highly unlikely modprobe exit code, check changing condition: ... ret="$?"; if [[ "$ret" = "124" ]]; echo timeout; other command; elif [[

eclipse deployed cvs client plugin default. why there no svn source control clients bundled default? there's discussion sheds light on potential problems integrating various svn plug-ins exist eclipse. from tigris' status of eclipse svn proposal : one final factor in decision [to withdraw proposal] licensing. subversion plug-in going depend on either subversion's javahl library or svnkit pure java library. svnkit's license rejected eclipse, , in case of subversion planning review code before allowing use library. subversion has dependencies on libraries neon , bdb have licenses not typically accepted eclipse. had question whether able include javahl or svnkit our plug-in. again, maybe turn out not issue subversive. so various licensing problems appears crux of including existing svn plug-in default.

i have javascript function goes this: function change_one() { var 1 = document.getelementbyid("one").value; document.getelementbyid("tag").value=one; } it works fine until there 2 elements same id. i'm using php fetch stuff mysql , while it's looping thru, it's echoing input tags have same id value. how javascript code apply of input tags have id equal "one"? "it works fine until there 2 elements same id." that's invalid. best solution change php code use classes, or way distinguish. may find helpful use javascript library find elements matching class. edit: using jquery, tag , one classes: function change_one() { $(".tag").val($(".one").val()); }

what's difference between ob_flush() , flush() , why must call both? the ob_flush() reference says: this function send contents of output buffer (if any). the flush() reference says: flushes write buffers of php , whatever backend php using (cgi, web server, etc). however, continues say: [it] may not able override buffering scheme of web server… so, seems me use ob_flush() of time. however, strange results when that. explain in simple terms what's going on here? ob_flush sends application-initiated buffer. there may multiple nested ob_start() 's in php script. ob_flush passes current content upper layer. php might (at own discretion) buffer output. depends on back-end. fastcgi has socket buffer on own. therefore flush() needs invoked send current content web server. and web server might implement buffering scheme ( mod_deflate or content filter), have no influence over. seldom, needs configured specifically. anyway,

i'm novice programmer trying automate repetitive workplace tasks should done clever script instead of humans. i've done vba , java, basic stuff. we have data generated validated online form gets emailed mailbox, , filter in mail client (outlook 2010) puts particular folder. intention write vba when triggered check contents of folder, , each mail item, message body text string, create array, , write array contents .csv file. i'll have app (imacros firefox) read csv , interact in-house corporate webapp rest. i think can of except write array contents csv. i work best looking @ code examples (i try understand ms object model documentation), best can find writing vba array csv like: 'save file open sfilename output #7 n = 0 ubound(myarray, 1) print #7, format(myarray(n, 0), "0.000000e+00") next n close #7 i think vb , not vba, general idea here valid? or if else has code sample me started or other pointers i'd grateful. ps have se

i've created visual studio 2010 asp.net mvc project template vsix package i'd upload visual studio gallery, every time try tells me path long... locally, installs , works without issue... the structure of project (zipped t.zip try , reduce length) standard mvc structured project, caveat needs (well, doesn't need makes sense there) installs web sub-folder under c# language, path inside vsix package projecttemplate\csharp\web . is there way around limitation, or doing wrong? there check when upload vs gallery see if path length might end being long when installed on users machine. check includes not files directly in vsix, files embedded inside zip file. (this because templates unzipped on disk before used instantiating new project.) unfortunately, think option shorten-up paths of files in template itself.

django comes unicode support out of box , supports utf-8 default. have developed, debugged , tested site bunch of django apps in utf-8. steps required painless migration different encoding, latin-1 ? wish need setting default_charset = 'latin-1' , changing encoding of database somehow doubt simple. for sake of discussion can ignore migration of stored utf-8 data in database; i'm interested in required checks , changes in django code database , web server configuration. you shouldn't need make significant changes django codebase. though working characterset utf-8, data stored in database using database's chosen encoding. do have really reason moving utf-8 latin-1? if you're concerned character encoding of output, want deal using referenced setting, rather @ database level may lose data. there's more info here: http://docs.djangoproject.com/en/dev/ref/unicode/

i have document library list. created folders in list , uploaded files sub folders. how these files in sub-folders in document library list using spquery ? if want query folders , sub folders of list or document library, have define query options. if working object model have set viewattributes property of spquery object follows: qry.viewattributes = "scope='recursive'";

in our project use jai showing parts of image, rotating image , basic zooming in applet. observe applet takes lot of time load - around 20 seconds first time. subsequently, takes 3 seconds (which quite high). jai development seems have frozen since 2007.atleast not find download post 2007 on java website. has encountered loading issues , solved them in context of jai ? there performant alternative jai ? images using in tiff format , can have multiple images in 1 physical file. any pointers appreciated. the first application startup (cold startup) require lot of time, need load tons of libraries including jai. second , next application startups (warm startup) faster runtime classes cached in classes.jsa . then, image processing require cpu , in order paint it, graphics card. modern computers image processing (basic operations!) , handling (zoom, pan) trivial , fast jai. we have developed , image reviewing application jai + image i/o , zoom , panning extremely f

i making geometry library , confused, should return type of function calculates intersection of segment segment. returned value point , segment (overlap case) , empty set. per thinking there 3 ways tackle per follows: 1. return union (segment, null, point) 2. return segment first point == second point when intersection single point , both points nan when intersection empty set 3. return vector (with 0 elements empty set, 1 element pnt , 2 elements segment) please let me know if there alternates possible , pros , cons of each of design. design supposed design , why. interested in making robust architecture lets single pipe-lining , no rewriting of code scalable (in terms of adding functionality , handling edge cases) following code reference (whose return type vector) vector<pnt> seg::inter(seg z){ vector<pnt> ans; if(p1==p2){if(z.doesinter(p1)){ans.pb(p1);}} else if(z.p1==z.p2){ if(doesinter(z.p1)) ans.pb(z.p1);} else{ pnt p1p2=(p2-p1); pnt q1=p1p2*pnt(0,1); long

i'm talking library allow me log events different machines , align these events on "global" time axis sufficiently high precision. actually, i'm asking because i've written such thing myself in course of cluster computing project, found terrifically useful, , surprised couldn't find analogues. therefore, point whether exists (and better contribute it) or nothing exists (and better write open-source analogue of solution). here features i'd expect such library: independence on clock offset between different machines timing precision on order of @ least milliseconds, preferably microseconds scalability thousands of concurrent logging processes, @ least several megabytes of aggregated logs per second soft real-time operation (t.i. don't want collect 200 big logs 200 machines , compute clock offsets , merge them - want see happens "live", perhaps small lag 10s) facebook's contribution in matter called ' scribe &#

i have requirement need play audio file in receiver mode(earpiece).i not sure whether higher versions of android sdk supports receiver mode.i went through links said 1.5/1.6 having changes in these audio apis , hence not sure. :( can please help? thanks. i believe long play audio file using mediaplayer , direct audio proper place (i.e. use ear piece output if headset connected etc.). could you're looking setspeakerphoneon(true) function in audiomanager class: sets speakerphone on or off. this method should used applications replace platform-wide management of audio settings or main telephony application.

i have image don't want drag-able or selectable no drag other places on page. how done? it impossible prevent store image (or other resources) on computer others have mentioned. but trick make harder (impossible inexperienced people guess) use css , background images: <div style='background: url("myimage.gif");'></div> the image on background of <div> block , cannot dragged or right clicked in order save it. using coding knowledge possible ind out myimage.gif part, can added after base url in order download image , save it. example if html page @ http://www.example.com/mypage.html image found @ http://www.example.com/myimage.gif as mentioned still possible save image, inexperienced people lot harder. note : in example image put in html tag, proper use of css file, harder find inexperienced people.

it possible declare class without defining (forward declaration) long defined later on within translation unit. in case of functions, 1 can declare function without defining within translation unit, , linker link definition in different translation unit. possible same class declarations? (if not possible, there any use forwardly declared class without definition in current tl, or error?) something this, except doesn't compile: mymain.cpp: class myclass; // declare without defining myclass::myclass(); void myclass::barf(); int main() { myclass *m = new myclass(); m->barf(); return 0; } myclass.cpp: #include <iostream> class myclass { // define implementation public: myclass(); void barf(); }; myclass::myclass() { } //empty constructor void myclass::barf() { std::cout << "barfing\n"; } it possible forward-declare class, pointers , references forward-declared classes can used. can't use actual object of forwa

in ruby, there way determine files loaded , defined/modified particular class? i don't think there's easy way correctly, approximation in 1.9 find source_location methods in class: class class def source_files methods.collect { |method_name| method(method_name).source_location[0] # filename, not line number } | instance_methods.collect { |method_name| instance_method(method_name).source_location[0] } end end this give files defining methods inherited superclass or included modules, i'm not sure whether want. there ways modify class besides defining methods in it, doesn't detect them, it's not perfect.

i'm new asp.net mvc. i created default asp.net mvc project in vs , can see when make call controller's action this: "http://localhost:2528/home/about" home controller has action method "about" returning about.aspx view. seeing not seeing .aspx extension in browser's url. , when try browse "http://localhost:2528/home/about.aspx" 404 error. i have requirement need create .aspx page passed arguement via url this: "http://... /myaspxpagehere.aspx?argname=myarg" i'm not sure how asp.net mvc. and/or code examples appreciated. thanks asp.net mvc not use .aspx extension in client-facing urls. if want accept arguments querystring, should add parameters action methods.

i'm looking tips implement binary --version provide information version compiled from. the project using autotools build system, , stored in git repo acts svn frontend. what have inside binary is: compilation time svn commit acts base last git commit id , time if possible last commit affects specific binary you'll want write source code use #defined constant version string. can pass in through build -dmy_version=... option. that'll let embed default value in code, too, wrapped in #ifndef , in case! #ifndef my_version #define my_version 0.0.1-alpha #endif print_version() { printf("my product: %s\n", my_version); } a nice way handle on build process side make intermediate build product makefile snippet my_version = "..." . again adds redundancy letting distribute project version file created, build doesn't have depend on presence of scm. you can create version string like, example: echo -n 'my_version = "

i'm gathering light statistics of exif data large collection of photos , i'm trying find simplest way (i.e. performance doesn't matter) of translating exposure time values to/from usable data . there (as far can find) no standard values camera manufacturers might use i.e. can't scan web random images , hard-code map. here sample set of values i've encountered ( " indicates seconds): 279", 30", 5", 3.2", 1.6", 1.3", 1", 1/1.3, 1/1.6, 1/2, 1/2.5, 1/3, 1/4, 1/5, 1/8, 1/13, 1/8000, 1/16000 also take consideration i'd find average (mean) ... should 1 of actual shutter speeds collected , not arbitrary number. edit: usable data mean sort of creative? numbering system can convert to/from performing calculations. thought multiplying 1,000,000 except fractions when divided quite exotic. edit #2: clarify, i'm using exposuretime instead of shutterspeed because contains photographer friendly values e.g. 1/50.

i have square matrix of size 'n' made of numbers (1 n) irregular clustered.for example 7's together, 10's together, etc, irregularly. using "image , colormap" command matrix each cluster colored differently square edges.. want ruffle edges there smooth boundary between each color. need ramps in place of steps! beginner in matlab. pl help........... you can convolve array kind of low-pass (i.e. smoothing) filter. if want ramps straight lines, can use average filter; if want ramps sigmoidal, can use gaussian filter. size of filter window determines width of ramp. for example, use 3x3 average filter (which give ramps of width 3 pixel), you'd following: %# pad image twice replicating borders avoid border effects %# use padarray instead if have image processing toolbox tmp = img([1 1 1:end end end],[1 1 1:end end end]); %# apply convolution. normalize filter sum %# of pixels in filter 1, , use 'valid' option %# automatically discar
