i've been trying implement video camera. never worked because of mysterious error (-16) on recorder.start(). here code: private void initrecorder(int width, int height) { recorder.setaudiosource(mediarecorder.audiosource.camcorder); recorder.setvideosource(mediarecorder.videosource.camera); parameters params = camera.getparameters(); list<size> sizes = params.getsupportedpreviewsizes(); size optimalsize = getoptimalpreviewsize(sizes, width, height); params.setpreviewsize(optimalsize.width, optimalsize.height); camcorderprofile cphigh = camcorderprofile .get(camcorderprofile.quality_low); recorder.setprofile(cphigh); file mediafile = null; if (environment.getexternalstoragestate().equals( environment.media_mounted)) { mediafile = new file( android.os.environment.getexternalstoragedirectory() + &qu

i attempting generalize test code in solution mvc project. because we're writing same test each controller, thought use generics make 1 test needed. unfortunately, i'm getting error: error 1 type 'trepo' must reference type in order use parameter 't' in generic type or method 'moq.mock<t>' here's relevant code. can provide more if needed. testbase.cs public class testbase<tcontroller, tobject, trepo> tcontroller : irmccontroller<tobject> trepo : irmcrepository { public mock<trepo> repo { get; set; } } companiestest.cs public class companiestest : testbase<companiescontroller, company, icompanyrepository> thanks help. in moq, mock<t> class has class constraint on generic type. here's how it's defined: public class mock<t> : mock t : class so if intend use in class must define same class constraint in addition irmcrepository : public class testbase<tcontroll

i need plot multiple markers on google map , having trouble placing more 1 marker. this works: https://maps.google.com/maps?q=26.549431,-81.847559 this not: https://maps.google.com/maps?q=26.549431,-81.847559&q=26.549579,-81.847757 is there way send 2 coordinates google maps , return 2 markers? using staticmap in google map api did trick: http://maps.google.com/maps/api/staticmap?zoom=9&size=640x480&maptype=roadmap%20&markers=label:1|26.785,-82.045&markers=label:2|26.651,-82.0&markers=label:3|26.7,-81.75634&markers=label:4|26.6,-81.89&markers=label:5|26.475,-81.79&markers=label:6|26.41,-81.76&markers=label:7|26.42,-81.78&markers=label:8|26.43,-81.80&markers=label:9|26.44,-81.82&markers=label:10|26.45,-81.84&sensor=false

i have view i'd declare in hbs: {{view app.componentview title="text field" optionstemplate="textfieldoptions" }} {{view app.componentview title="static label" optionstemplate="statiffieldoptions"}} then in view definition i'd following: app.componentview = ember.view.extend({ templatename="blah", attributebindings:["data-type", "draggable", "title", "rel", "data-trigger", "data-content"], optionstemplate:null, "data-content": function() { var renderedoptionstemplate = em.xxx(this.get("optionstemplate")); return renderedoptionstemplate; }.property(), //snip }); what i'm looking should put in place intead of em.xxx call there. possible? can using either partial or template or whatever...

i have field logo=models.imagefield(upload_to="restaurant_detail/restaurant_detail", help_text = "upload restaurant logo") this returns error, data truncated column 'logo' @ row 1 so go ahead fix statement alter table my_table modify logo varchar(500) (i increase characters.) this works everytime reset database have again and when try , execute alter statement above , insert data, still fails data truncated column 'logo' @ row 1 error. how permanently fix without having alter table time? change field definition to: logo = models.imagefield(max_length=500, upload_to="restaurant_detail/restaurant_detail", help_text="upload restaurant logo") i added max_length kwarg tells django how many chars field can store , cause database field created appropriately.

i have imput field in form multiple(two) backgrounds this: background: url(framework/images/search.png) no-repeat 6px 7px, /*this magnifying glass icon - important later */ rgba(200,200,200,0.1); then i've got transition: transition:background 0.2s linear, box-shadow 0.5s linear; and on focus of input field: input:focus, { background:rgba(0,0,0,0.1); box-shadow:0px 1px 0px rgba(0,0,0,0.1) inset; } basically (or should) when input field active background changes darker color transitions. box shadow makes inner effect of inside border. case when background of 1 element (only background color). when added icon on higher layer background wont change, box-shadow works. think browser confused how change color of bitmap image. my question is: there way transition 1 layer of background (address somehow), bitmap image stay same , color change? thank you. edit: jsfiddle -> http://jsfiddle.net/8drtt/ http://jsfiddle.net/8drtt/1/ input:focus

i'm running code, consist in find average values. in ~6 million lines csv (ssm_resnik.txt), first row 1 reference, second row , third value 'distance' between 2 references. such distances arbitrarly defined biological criteria not important issue. of the references versus... of references, hence huge csv more 6 millions of lines. in csv (all_spot_uniprot.txt) have ~3600 spot's (first column), each of them 1 or more reference (third column). values same of huge csv. need compare each of 3600 of spot ref of second file other 3600-1 ref's in same file. of possible combinations, if exists, in first, huge csv file (ssm_resnik.txt). all_spot_uniprot.txt, each 2 spot ref's serve iterator correspondent reference (in third column) , iterate on huge csv file that, if exists, show value 2 "vs" reference. what problem code? well... 10 seconds each iteration, 3600 *3600 *10 = 129.600.000 seconds = 1500 days (almost 5 years). happens in core i3, in mac. below

so have element behind another, it's still visible(its covered partially element itself, otherwise covered margin attribute of element above). want trigger mouse event when mouse over, doesn't passed because of element in front. know how calculate if on , how point it, don't know how send event onmouseover or hover or onmouseout . if helps pointing @ using document.getelementbyid("<calculated id>") . know works because it's id based off of location within grid, have calculate position of mouse , relate grid. also event supposed happen(but isn't because of things in front of it), :hover triggers simple transition animation via css. document.getelementbyid('elementinfront').addeventlistener('mouseenter', function(){ document.getelementbyid('elementbehind').doyourstuff(); });

i'm trying method work: that.model.save(null, // i'm calling that.model because nested in method { url: 'some url', success: function(model, response) { // update stuff }, error: function(model, response) { // throw error. } }); but reason not call success method or error method. comments i'm calling methods... don't want specifics of methods i'm calling. save method works, not call eater of methods. also if try , call method alrady made like: success: that.somemethod() javascript throws: uncaught typeerror: illegal invocation any appreciated. the method looks fine uses same arguments backbone describes: model.save([attributes], [options]) the scenario success/error handlers being overridden somewhere prototype chain , not calling handlers.

some background: i'm using oncfcrequest() handle remote cfc calls separately regular cfm page requests. allows me catch errors , set mime types cleanly remote requests. the problem: i accidentally set of remote cfc functions public access instead of remote , realized still working when called remotely. as can see below, implementation of oncfcrequest() has created gaping security hole entire application, an http request used invoke public method on http-accessible cfc. repro code: in application.cfc: public function oncfcrequest(string cfc, string method, struct args){ cfc = createobject('component', cfc); return evaluate('cfc.#method#(argumentcollection=args)'); } in cfc called remotely: public function publicfunction(){ return 'public function called remotely!'; } question: i know check meta data component before invoking method verify allows remote access, there other ways approach pro

i trying use c program (via dynamic libraries) python , ctypes module. several constants defined in header file important me, unsure of how enum being used set values. the obvious ones, think understand like: enum{thing1, thing2, thing3}; thing1=0, thing2=1, thing3=3 but, this? enum{thing1=-1, thing2, thing3}; is result: thing1=-1, thing2=1, thing3=2 ? what one? enum{thing1=1, thing2, thing3, thing4=-1} ? i don't have easy way test this, hoping can explain way enum works in context. c books looked in seemed cover either first case or case each value explicitly defined, not mixed case. many in advance! the value of first enum constant 0, unless specified otherwise. the value of other enum constant 1 more value of previous, unless explicitly specified. so enum{thing1=-1, thing2, thing3}; sets thing2 = 0, thing3 = 1 , and enum{thing1=1, thing2, thing3, thing4=-1} sets thing2 = 2, thing3 = 3 (and thing4 = -1 explicitly given).

if have input type="file" somewhere, , on click of link triggers click on file input. user picks file. in ie8/9 if user clicks on button type="submit" first click clears data in file input, second submits blank form. how allow submission of input type="file" post javascript click trigger. some notes: the click triggered consequence of click event. within event. the input type="file" not set display: none. no attempt manipulate user input done ideas? i've been struggling same problem, , i'm yet come across clean solution. i have however, discovered work-around. please note the solutions below disregard best practices (in humble opinion) , if has better, more standards-compliant way of doing this, please post here. fixing button click event after fair amount of research, seems lot of people using trick whereby absolutely position <input type="file" /> on button, , set opacity zero. means

question why random ascii character selector function outputting fours, , significance of number 4 in context? why not recieving error message? remember, question not how solve issue, why particular number output. background , code i trying creating basic email client. thought cool password box show random characters instead of obvious *. so, created function chose random ascii letter. import random import string def random_char(): char_select = random.randrange(52) char_choice = string.ascii_letters[char_select] return char_choice when run in interactive terminal, spits out random letter. but, when run through widget self.password = entry (self, show = lambda: random_char()) i met bunch of fours. extra credit if have time, please visit related question, how have tkinter entry box repeat function each time character inputted? the show parameter accepts value not callback. tkinter taking callback object , trying convert string , when typ

i'm attempting use jquery waypoints plugin greasemonkey script, , can't seem basic tests work. know of reason waypoints wouldn't work user script? @require lines: // @require http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js // @require http://cdn.jsdelivr.net/jquery.waypoints/2.0.2/waypoints.min.js script: $('div.container').waypoint(function(){ alert('you hit bottom'); },{ offset: 'bottom-in-view' }); interestingly, if div "container" class exists, script breaks, , code outside statement not run. if change selector find non-existent element, rest of script runs fine. does have idea what's going on here? i'm banging head against wall. thanks! ps. i've tried pasting waypoints plugin code directly script (instead of using cdn), , same results. unfortunately, extension not written many other jquery extensions. uses this , , jquery in, let's say, "unfortunate" way

mysql provides fulltext indexes, can retrieved match (col1,col2,...) against (expr [search_modifier]) construct. there several full-text search variants, 1 of them (and default one) natural language full-text search . so maximal possible value of match ('...' in natural language mode)? example: this query select courses.id, courses.title, match (coursedata.title) against ('basketball') relevance courses join coursedata on coursedata.id = courses.coursedata_id match (coursedata.title) against ('basketball') > 0 returns result table column relevance , we're storing relevance value of coursedata.title rows 'basketball' . or relevance value of 'basketball' coursedata.title rows? anyway, we're storing there output of match(...) function. in case i'm geting values 0 3.695953130722046 . there not small limit possibilities of query output. instead of reaching huge limit, freeze down

i want keep track of values of instance variable, , breakpoint starts @ static method. can't check instance variable value. there way that? searched on google, found no clue. is because instance can't accessed in static method? you pass variable tracking method. although make note every time can remove when done testing. but honestly, if don't have access variable within method, won't change time have exited method, unless have multiple threads. therefore, can set breakpoint after/before method called.

i have chef, workstation , nodes provisioned through hosted chef. need work on nodes in ruby script, not cookbook/recipe, using chef::search query them. i have array of chef::nodes in script, , want handle on each node's chef-client can run recipe on each one. remember not doing regular chef run, need mimic chef run does: pulls down nodes, expands run_lists , run recipes on them needed. why? because, not provisioning; need check status of nodes , select particular 1 run recipe on. nodes provisioned mongo , need maintenance replica set. cannot run sequential recipes , cannot run 1 of nodes. so need is: given chef::node got form chef::search::query , how 1 chef-client or load new chef::client ? i have extensively looked @ api , chef::client class doesn't seem telling me how. there initialize , loadnode nothing takes node. i think can lot of asking using knife-exec . allows you, if have api key, manipulate data on chef server ruby script. inc

git push used push changes remote repository. git diff shows changes made since last pull operation remote repository. git diff synonymously used git patch . after getting difference, patch applied through git am or git apply repository updation. so, these 2 commands fundamentally same or there difference between git diff , git push ? git push push changes made in file repository. last step make add change project. git diff used see changes made different files since last commit. shows line added or removed project. the basic flow goes this. you make changes in project. -> git add -> git diff if want see changes have been made -> commit using git commit -> push committed changes repository using git push . if new git, learn interactive tutorial http://try.github.com/

what happens if there 2 people sending same query @ same time database , 1 makes other query return different? i have shop there 1 item left. 2 or more people buy item , query arrives @ exact same time on mysql server. guess queue if so, how mysql pick first 1 execute , can have influence on this? sending same query @ same time queries not run in parallel it depends on database engine. myisam, every query acquires table level lock meaning queries run sequentially queue. of other engines may run in parallel. echo_me says nothing happens @ exact same time , cpu not @ once that's not true. it's possible dbms run on machine more 1 cpu, , more 1 network interface. it's very improbable 2 queries arrive @ same time - not impossible, hence there mutex ensure paring/execution transition runs single thread (of execution - not necesarily same light weight process). there's 2 approaches solving concurent dml - either use transactions (where each user g

i'm making windows 8 store app using html, javascript, , css. app allows user make lists, , manage items inside of lists. i've managed edit lists , want, problem once close app, reset, because none of changes dom made (such elements added or removed) saved, , lose of lists , items made. possible edit dom in such way edits actual html file, did still there once open app again? if not, alternate methods saving user data once app closed? thanks, daniel this may late hope helps. you can use html local storage.with local storage, web applications can store data locally within user's browser. before html5, application data had stored in cookies, included in every server request. local storage more secure, , large amounts of data can stored locally, without affecting website performance. unlike cookies, storage limit far larger (at least 5mb) , information never transferred server. local storage per origin (per domain , protocol). pages, 1 origin, can store

i'm trying use custom font in rails app, can't figure out i'm doing wrong. i've created folder called fonts in assets folder 2 fonts i'm using. , call 2 fonts in css file called home.css.scss.erb css: @font-face { font-family: 'proxima nova'; src: url('<%= asset_path(/assets/fonts/proximanova-regular.otf) %>', font); font-weight: normal; font-style: normal; } @font-face { font-family: 'gotham'; src: url('<%= asset_path(/assets/fonts/gotham-medium.ttf) %>', font); font-weight: normal; font-style: normal; } then in config folder in application.rb i've added config.assets.paths << "#{rails.root}/app/assets/fonts" but still doesn't seem working.. ideas why? i've used custom fonts before never need use asset_path helper. using relative path in css should enough. settings similar these: # config/application.rb config.assets.paths << rails.root.join("asset

in appdelegate.m file have created following button style: uiimage *backbtnimage = [uiimage imagenamed:@"back.png"]; [[uibarbuttonitem appearance] setbackbuttonbackgroundimage: backbtnimage forstate: uicontrolstatenormal barmetrics: uibarmetricsdefault]; [[uibarbuttonitem appearance] setbackbuttonbackgroundimage: backbtnimage forstate: uicontrolstatehighlighted barmetrics: uibarmetricsdefault]; for reason background image shows on each view after space button is tapped once - loads everytime each view after that. i've tried cleaning project no avail. hmm, if running on simulator, try reseting content , settings, if doesnt work, know ios devices have issues caching, try changing photo name.png in both actual file , reference in xcode.

i spawning processes popen (python 2.7, shell=true) , sending sigint them. appears process group leader python process, sending sigint pid returned popen, pid of bash, doesn't anything. so, there way make popen create new process group? can see there flag called subprocess.create_new_process_group, windows. i'm upgrading legacy scripts running python2.6 , seems python2.6 default behavior want (i.e. new process group when popen). bash not handle signals while waiting foreground child process complete. why sending sigint not anything. behaviour has nothing process groups. there couple of options let child process receive sigint : when spawning new process shell=true try prepending exec front of command line, bash gets replaced child process. when spawning new process shell=true append command line & wait %- . cause bash react signals while waiting child process complete. won't forward signal child process. use shell=false , specify full paths
