i have page displays image, along metadata it. image , metadata should centered in page. i'd div containing metadata wide image. sorta so: unfortunately, it's not possible me reliably determine image's width before serving page. right i'm using listener on load: $('.image-container img').one('load', function() { $('.image-container, .image-container *').css('max-width', $(this).width()); }); this works, if image large , takes while load, page looks crappy until finishes. i'm looking either: a way use css express container should wide image inside it. an event fires browser gets enough information know image's width (which pretty on, can see). thanks! this quite easy without jquery. set container display:inline-block this: div {display:inline-block; margin:0; padding:0;} example in fiddle (image size 600px x400px)

i'm using netbeans 7.4 java ee project school. when open netbeans, background scanning of project takes ages. if check ide log, see alot of info netbeans not beeing able read symbolic links files in library. these links files in frameworks folder. before, netbeans scanned folder named tex in de library, deleted that, since didn't need anymore, deleting frameworks folder don't trust much. since netbeans keeps scanning, can't run project. can me?

i'm working on making spare raspberry pi headless bittorrent box, using deluge. most guides on setting deluge on linux include custom startup script run @ boot. however, when you're ssh'd pi, can start deluged daemon typing in "deluged". however, when wrote basic bash script ran command, put in /etc/init.d/ , added using update-rc.d, didn't work. nano /etc/init.d/startdeluged.sh chmod 755 /etc/init.d/startdeluged.sh update-rc.d startdeluged.sh defaults the bash script contained this: #!/bin/sh deluged exit i'm new setting startup scripts on linux, , i'm wondering why special script necessary when running command in terminal has same effect. have user entering command? you must add begin init infos after #!/bin/sh . looks : ### begin init info # provides: scriptname # required-start: $remote_fs $syslog # required-stop: $remote_fs $syslog # default-start: 2 3 4 5 # default-stop: 0 1 6 # short-descript

so having bit of bother combining 2 columns one. have 2 columns of ages, split child , adolescent columns. example: child adolescent 1 na 12 2 na 15 3 na 12 4 na 12 5 na 13 6 na 13 7 na 13 8 na 14 9 14 15 10 na 12 11 12 13 12 na 12 13 na 13 14 na 14 15 na 14 16 12 13 17 na 14 18 na 13 19 na 13 20 na 14 21 na 12 22 na 13 23 12 15 24 na 13 25 na 15 26 na 12 27 na 15 28 na 15 29 na 13 30 na 12 31 13 15` now combine them 1 column called "age" , remove na values. when try following code, encounter problem: age<- c(na.omit(data$child),na.omit(data$adolescent)) the problem being original data has 514 rows, yet when combine 2 columns, removing nas, somehow end 543 values, not 514 , don't know why. so, if possible, explain firstly why getting more values planned, , secondly might better way combine 2 columns. edit: looking this age 1 12 2 15 3 12 4 12 5 13 6 13 7 13 8 14

i want add on existing project sockets nodejs , socket.io. have 2 servers : an api restful web service, storage , manage datas. a public web service return html, assets (js, css, images, ...) on first try, create socket server on public one. think better if create other 1 handle socket query. what think ? it's idea or useless add more problem solve (maybe duplicate intern lib, ..) also, i'm using token communicate between public , api, have create communication between socket , api ? or can use same 1 ? ------[edit]------ as nobody didn't understand me have create schema infrastructure thinking about. it way proceed ? the public server , socket server have same ? or can separate ? do must create socket connection between api , socket server each client connected ? thank ! thanks explaining better. first of all, while seems reasonable, way of using socket.io not common one. biggest advantage of using socket.io keeps channel open 2-way

please use code reference telling how giving ascii output int main() { char c; printf("enter character: "); scanf("%c",&c); /* takes character user */ printf("ascii value of %c = %d",c,c); return 0; } the line printf("ascii value of %c = %d",c,c); will show value of c in 2 ways. firstly character, secondly number. whether or not ascii value, depends on c is, because ascii standard not encompass all of 256 values representable char or unsigned char . depends on system settings such code page, language, etc. moreover, not of ascii characters printable - terminal or console outputs use printable representation of number rather using control - although 7 might ring bell!

if want submit fields of nested resources instead of parent. how can this? i've got 2 models: product , product_details. =form_for @product |f| =f.fields_for product_details |ff| =ff.radio_button :price, ff.price =f.submit so need submit form above product_details_controller instead of products_controller. if form_form product_details got "to_key" undefined.. what best way this? accepts_nested_attributes_for can you. for example:- class project < activerecord::base has_many :tasks accept_nested_attributes_for :tasks, :allow_destroy => true end in view <% form_for @project |project_form| %> <% project_form.fields_for :tasks |task_form| %> <p> <div> <%= task_form.label :name, 'task:' %> <%= task_form.text_field :name %> </div> </p> <%end%> <%= project_form.submit %> <% end %> so @project.save save c

i don't understand buffer doing , how it's used.

below code playing audio in project.when click on play button changes pause button , playing audio through init() method inside application class.the issue facing after clicking on play button takes few seconds(5-10 seconds) after play button changes pause.but should change pause button first statement inside onclick() holder.pause.setvisibility(view.visible); . if comment out init method call line projectapplication.getinstance().init(mctxt, lmoment.getprojectmedialoc(), holder.lvisualizerview, laudioprogressbar,holder.image,holder.image2); changes pause button init method required playing audio.if use postdelayed() method , call init() method after 2 seconds works expected .but fail understand why init() method creating problem in changing visiblity of play , pause buttons init method() called after changing visiblity. holder.play.setonclicklistener(new view.onclicklistener() { @override public void onclick(view view)

there pitch , duration , sample rate fs "pitch" vector of note pitch in semitones (with 0 indicating silence), "duration" vector of note duration in seconds, "fs" sample rate of output wave signals playback. pitch= [55 55 55 55 57 55 0 57 60 0 ]; duration=[23 23 23 23 23 35 9 23 69 18 ]/64; fs=16000; i want use above info return audio signal in matlab. can teach me? thx this requires thought , might take time write down before working. personally, i'd split task multiple functions in mind involve: 1. semitone frequency 2. time sample number 3. frequency , sample number output waveform and if possible should add array involves level further progress later on/ helps simplify problem stages. as im not sure semitone scaling using have confirm need sort of converter/look table (formulas according physics of music website ): function [frequency] = semitone2frequency(semitone) %your input how many semitones above middle

how can make jfilechooser filter filter "file.txt", can make filter ".txt" thats not want. i'm going have string[] of files filter such as string[] filters = new string[filterscount]; string[0] = "file.txt"; string[1] = "text.txt"; string[2] = "uncaptext.txt"; i want able browse files exact names, capitalization count "uncaptext.txt" accepted "uncaptext.txt" or "uncaptext.txt" won't. this seems easy question couldn't find topic on it. i suggest writing filter checks for... return arrays.aslist(filters).contains(file.getname()); in other words, make list out of array (to have nice "contains" method) , ask list if name of file contained in it.

does tfs 2010 support new non-xml automatic package restore introduced of nuget 2.7. or (as suspect) 2013 upwards. as tfs 2010 on 5 years old there no new functionality added. so, no. not support advances since last update in 2011. you should consider upgrading tfs 2013 or preferably vso 2010 falls out of mainstream support in few months. http://nakedalm.com/its-that-time-again-get-ready-to-upgrade-to-tfs-2015/ if still on tfs 2010 question competency of whomever supporting tfs. that's long time behind when there no cost upgrading time. if common problem in organisation vso better solution.
