• When page loads display 1st image text - hide all other text

  - by Jonah1289

  Hi I have created http://techavid.com/design/test3.html and when you load the page you see there are 3 images. The sun image is focused(in color), while the others are greyed out until clicked. That is how it should be for the images. Also when you load the page you see under each image it's own text(i.e. 1st: Sun, 2nd: Airplane, 3rd: Nano), but on page load I only want 1st:Sun to display and hide all other text until their respective image is clicked. Any idea how to do this? thanks :) J

• Bypass OpenID. Please give us a simple login form.

  - by Florin

  Can I kindly ask that we're allowed to login without the OpenID nonsense? This system is so popular that stack-overflow is the only place that I use it. If it is the policy of stack-overflow to prevent people to login, they've succeeded. I am a passive reader. For some reasons, I really don't like the idea of having one Id for all sites. To me, this system is dead in the water. Unless used within organizations I will never use it. Of course, until the government decides to reign us all in. Will you give them a hand? Until then, can we simply have a login form as in 1995? Thank you for your consideration.

• CoreDumpDirectory isn't working on ubuntu; getting segmentation fault with php

  - by siran

  I'm trying to solve a segmentation fault. This message appears in my apache-error.log: [notice] child pid 3979 exit signal Segmentation fault (11) I've tried disabling some apache and php modules but I'm still getting the same error. I've also tried putting this in apache2.conf: CoreDumpDirectory /tmp/apache2-gdb-dump and then chmod 777, chown www-data... so that the server can write. I can see no core-dump files to give me a hint on the error. Does anybody have an idea why CoreDumpDirectory isn't working on Ubuntu?

• Ask StackOverFlow : Canny a LightWeight Authorization library in Java

  - by eltados

  In the course of my work i need to develop an authorization engine ( i'm already authenticated and i check access of a user to an action ) in order to store all the authorization logic inside a same place and be able to reuse it and i have created the mini library. http://github.com/eltados/canny (updated) what do you think about it? What are the limits of my approch ? Do you understand the benefit or it? Is there any lightweight Authorization engine library i could have a look at? I had a look at spring security and it does not really answer my requirement. The main idea is that i want to be able to reuse the same code to controll access in the controllers and the views.

• TCP Server to push data to a Web Browser

  - by isurulucky

  Hi, I have a TCP server, which is connected to a web page via a Web browser. It is easy to send a request to the TCP server by the web page via the Web Browser, but is there a way that TCP server can push data to the web browser, without waiting for a request from browser side?? My initial idea was that this is impossible, since a browser is stateless. But I was told there are ways to do that... Any ideas? Thank You!!

• core-plot and NSDate (iPhone)

  - by Urizen

  I wish to plot a line graph where the x-axis is defined as a number of days between two dates and the y-axis is a value that varies on each of the days. I can plot the y values as an NSNumber but I have no idea how to set the ranges and the markup on the x-axis. I have looked at the date example in the "examples" directory of the core-plot distribution but have found it a little confusing. Does anyone know of a tutorial, or code sample, which might asist me in this regard? Thank you in advance.

• Keep a Google Maps v3 Map Hidden, show when needed

  - by Dr1Ku

  Is there a way of preventing Google Maps (JS, v3) of being displayed from the get-go ? I do some pre-processing and would like to show my 'Loading' spinner until everything is good to go (more eloquently put, hide the map -- e.g. the container div -- until all preprocessing is complete -- at which point, show the map). Hooking to the map's 'idle' event doesn't help that much, since the map is already displayed when this event hits. I know that the container div gets inline-styled by GMaps after loading, my first idea is to clear out the style attr (whilst listening to 'idle'), but it would be interesting to see if there is a way of creating the map and not displaying it until all pre-processing is done. Maybe by using an argument to the new google.maps.Map constructor, or a MapOption ? Any thoughts on this ? Thank you in advance !

• Presentation to under privileged students about what programming is. How? Any ideas.

  - by Quigrim

  Next week I have to give a presentation to a group of under privileged college students about the possibilities of a career in software development. These students have no exposure to programming what-so-ever. I have a good idea of how to tackle the non-technical, general portion of the presentation. However, notwithstanding my decade of experience, I am finding myself at somewhat of a loss how to convey the concept of programming in a meaningful way in under 20 minutes. Do I demonstrate actual simple code, or do I stick with concepts? I need to be able to scratch the surface of the vastness of the programming realm, to create just enough of a handle to those students, to peak the interest of those who might have the aptitude for it. Any ideas that are concise and clear would be greatly appreciated. Also, if anybody knows of online resources that addresses this topic, please share. Looking forward to some great input from this community. Thank you.

• Javascript global variable not working properly?

  - by Fabian

  My jQuery code: $(document).ready(function() { chrome.extension.sendRequest({get: "height"}, function(response) { height = response.value; }); $("#id").css("height", height+"px"); }); You don't have to be concerned about the chrome.extension.sendRequest(), basically it communicates with a background page to fetch the value for "height" from localStorage and stores the value in global variable height. The problem lies in $("#id") not being assigned the height value. However if I were to modify it such that it is now: $(document).click(function() { $("#id").css("height", height+"px"); }); it works. Any idea why?

• XCode won't open: "Mac OS X platform is missing"

  - by Jan Hettich

  XCode won't open. I had it running fine a couple of weeks ago. Now I get the following error message when XCode tries to open: Internal Error File: /SourceCache/DevToolsBase/.../XCPlatformSpecification.m Line: 438 Object: <XCPlatformSp(ecification> Method: loadAllPlatforms The Mac OS X platform is missing - cannot set a default platform. Any idea what caused this or how I can recover? Changes I have made to my system (Snow Leopard) in the last couple of weeks include (a) allowing Software Update to run and (b) installing Eclipse IDE. But the problem may or may not be related to these changes.

• Fast parsing of PHP in C#

  - by Jessica Shea

  Hello there, I've got a requirement for parsing PHP files in C#. We essentially require some of the devs in another country to upload PHP files and once uploaded we need to check the php files and get a list of all the methods and classes/functions etc. I thought of using a regex but I can't workout if a function belongs to a class etc, so I was wondering if theres already something 'out there' that will parse out PHP files and spit out its functions (I'm trying to avoid writing a full blow AST implementation). Does anyone have any idea? I looked at Coco/R but I couldn't find a PHP grammar file. I'm using .NET 2.0 and C#.

• How can I use MVC ideas without using classes?

  - by jpjp

  As of right now, I am still shaky on classes, so I don't want to use any classes for my site. I'm still practicing with classes. But how can I implement the MVC idea without classes? Would this work for a MVC? index.php (the view) index_controller.php index_model.php Is this right for what a MVC should be? View: show html, css, forms Controller: get $_POST from forms and any data from the user, get info from db Model: do all the functions, insert/delete in db, etc Basically separate the HTML/css for the view, all the data collecting for the controller, and the logic for the model. And just connect them all using require_once.

• jquery cycle plugin using RSS feed images?

  - by Chris

  This could well be a terribly ignorant question, if so please forgive me: I'm using jquery cycle plugin to create an image rotator of recently posted images. Im using drupal 6.x and created an RSS feed of the recent images using the views module. I have no idea how to connect the two. Any suggestions? I have a feeling an RSS feed might not be the best way to go about this, but it's all I could come up with. Thanks for the help.

• Git is ignoring .git directories in subdirectories

  - by Danny

  I'm using git as a backup tool and 'roaming profile' for my $HOME directory between laptop and desktop. My problem is that under my $HOME I have a Development directory with multiple git projects I'm working on. Git will not allow me to add the subdirectories .git folders. So to commit to these projects I have to push the changes into my $HOME git repo, pull on laptop (where they were created and .git dir exsits) and commit. I've read about submodules, but it's not really what I want. I just want the children .git folders to be treated like any old directory so I can move them around and back them up. Has anyone done this or have an idea how I would?

• C++: Platform independent game lib?

  - by Martijn Courteaux

  Hi, I want to write a serious 2D game, and it would be nice if I have a version for Linux and one for Windows (and eventually OSX). Java is fantastic because it is platform independent. But Java is too slow to write a serious game. So, I thought to write it in C++. But C++ isn't very cross-platform friendly. I can find game libraries for Windows and libraries for Linux, but I'm searching one that I can use for both, by recompiling the source on a Windows platform and on a Linux platform. Are there engines for this or is this idea irrelevant? Isn't it that easy (recompiling)? Any advice and information about C++ libraries would be very very very appreciated!

• how to add a meta tag to the page template from Wordpress plugin?

  - by detj

  I want to add a meta tag like this one: <meta name="key" content="value" /> to some of the pages in Wordpress. I know, I can add this into my template and it will show up. But the thing is, I am not allowed to even touch the template. It's totally template independent. So, I have to add the meta tag only by doing something in my plugin code. I have tried wp_head action hook, but it is not working. Any idea of a workaround or anything to get the meta tag inside the head tags of the pages dynamically.

• Android - LinearLayout Horizontal with wrapping children

  - by kape123

  Is there a property to set for Android's LinearLayout that will enable it to properly wrap child controls? Meaning - I have changeable number of children and would like to lay out them horizontally like: Example: Control1, Control2, Control3, ... I do that by setting: ll.setOrientation(LinearLayout.HORIZONTAL); foreach (Child c in children) ll.addView(c); However, if I have large number of children, last one gets cuts off, instead of going to next line. Any idea how this can be fixed?

• port binding "problem" with Eclipse, Java, & Windows

  - by Jay

  Hi All, I use eclipse to develop a web based java application. My normal course of business is grab the next task tracking ticket. If there is a problem that needs to correcting, I run the application locally, which loads of a Jetty webserver, and binds to port 8080. After verifying the problem, I fix the problem, rebuild, and the re-run the application. The problem is, I far too often forget to close the jetty server before re-running. This generates the Java bind error: WARNING: failed [email protected]:8080: java.net.BindException: Address already in use: JVM_Bind I work in Windows, and was looking to see if there is command I could run to un-bind the port, but couldn't find an answer there. Does anyone here have a good idea of how to fix my problem, other than remember to shut down the old jetty instance before starting a new one? Thanks, Jay

• How can I asynchronously monitor a file in Perl?

  - by Hussain

  I am wondering if it is possible, and if so how, one could create a perl script that constantly monitors a file/db, and then call a subroutine to perform text processing if the file is changed. I'm pretty sure this would be possible using sockets, but this needs to be used for a webchat application on a site running on a shared host, and I'm not so sure sockets would be allowed on it. The basic idea is: create a listener for a chat file/database when the file is updated with a new message, call a subroutine the called subroutine will send the new message back to the browser to be displayed Thanks in advance.

• How would you go about tackling this problem? [SOLVED in C++]

  - by incrediman

  Intro: EDIT: See solution at the bottom of this question (c++) I have a programming contest coming up in about half a week, and I've been prepping :) I found a bunch of questions from this canadian competition, they're great practice: http://cemc.math.uwaterloo.ca/contests/computing/2009/stage2/day1.pdf I'm looking at problem B ("Dinner"). Any idea where to start? I can't really think of anything besides the naive approach (ie. trying all permutations) which would take too long to be a valid answer. Btw, the language there says c++ and pascal I think, but i don't care what language you use - I mean really all I want is a hint as to the direction I should proceed in, and perhpas a short explanation to go along with it. It feels like I'm missing something obvious... Of course extended speculation is more than welcome, but I just wanted to clarify that I'm not looking for a full solution here :) Short version of the question: You have a binary string N of length 1-100 (in the question they use H's and G's instead of one's and 0's). You must remove all of the digits from it, in the least number of steps possible. In each step you may remove any number of adjacent digits so long as they are the same. That is, in each step you can remove any number of adjacent G's, or any number of adjacent H's, but you can't remove H's and G's in one step. Example: HHHGHHGHH Solution to the example: 1. HHGGHH (remove middle Hs) 2. HHHH (remove middle Gs) 3. Done (remove Hs) -->Would return '3' as the answer. Note that there can also be a limit placed on how large adjacent groups have to be when you remove them. For example it might say '2', and then you can't remove single digits (you'd have to remove pairs or larger groups at a time). Solution I took Mark Harrison's main algorithm, and Paradigm's grouping idea and used them to create the solution below. You can try it out on the official test cases if you want. //B.cpp //include debug messages? #define DEBUG false #include <iostream> #include <stdio.h> #include <vector> using namespace std; #define FOR(i,n) for (int i=0;i<n;i++) #define FROM(i,s,n) for (int i=s;i<n;i++) #define H 'H' #define G 'G' class String{ public: int num; char type; String(){ type=H; num=0; } String(char type){ this->type=type; num=1; } }; //n is the number of bits originally in the line //k is the minimum number of people you can remove at a time //moves is the counter used to determine how many moves we've made so far int n, k, moves; int main(){ /*Input from File*/ scanf("%d %d",&n,&k); char * buffer = new char[200]; scanf("%s",buffer); /*Process input into a vector*/ //the 'line' is a vector of 'String's (essentially contigious groups of identical 'bits') vector<String> line; line.push_back(String()); FOR(i,n){ //if the last String is of the correct type, simply increment its count if (line.back().type==buffer[i]) line.back().num++; //if the last String is of the wrong type but has a 0 count, correct its type and set its count to 1 else if (line.back().num==0){ line.back().type=buffer[i]; line.back().num=1; } //otherwise this is the beginning of a new group, so create the new group at the back with the correct type, and a count of 1 else{ line.push_back(String(buffer[i])); } } /*Geedily remove groups until there are at most two groups left*/ moves=0; int I;//the position of the best group to remove int bestNum;//the size of the newly connected group the removal of group I will create while (line.size()>2){ /*START DEBUG*/ if (DEBUG){ cout<<"\n"<<moves<<"\n----\n"; FOR(i,line.size()) printf("%d %c \n",line[i].num,line[i].type); cout<<"----\n"; } /*END DEBUG*/ I=1; bestNum=-1; FROM(i,1,line.size()-1){ if (line[i-1].num+line[i+1].num>bestNum && line[i].num>=k){ bestNum=line[i-1].num+line[i+1].num; I=i; } } //remove the chosen group, thus merging the two adjacent groups line[I-1].num+=line[I+1].num; line.erase(line.begin()+I);line.erase(line.begin()+I); moves++; } /*START DEBUG*/ if (DEBUG){ cout<<"\n"<<moves<<"\n----\n"; FOR(i,line.size()) printf("%d %c \n",line[i].num,line[i].type); cout<<"----\n"; cout<<"\n\nFinal Answer: "; } /*END DEBUG*/ /*Attempt the removal of the last two groups, and output the final result*/ if (line.size()==2 && line[0].num>=k && line[1].num>=k) cout<<moves+2;//success else if (line.size()==1 && line[0].num>=k) cout<<moves+1;//success else cout<<-1;//not everyone could dine. /*START DEBUG*/ if (DEBUG){ cout<<" moves."; } /*END DEBUG*/ }

• generate images with labels from a database

  - by Duncan Benoit

  hi there I need to have some images into my database, and the thing is that i need that images to have certain file names, dimensions and text on it. I know how to generate some images using the opencv lib, but this means that i need to install the lib and do just that job(which sounds as reinventing the wheel). Do you think is worth to do that or maybe you have a better idea? ps: the images are for testing stage of a software application, so i don;t need anything fancy or artistic.
