• Debugging PHP in Aptana 2.0

  - by Nick Lowman

  I'm a real newbie when it comes to PHP debugging so forgive my stupidity. I have a simple html form that submits to a PHP script and I want to debug that script and see what's being sent from the form. My Aptana has two two PHP interpreters installed; Zend Debugger on port 10001 and XDebug on 9000 I have the Firefox Aptana Addon installed I have my HTML page on the following url, running locally; http://3i/latest.html In the IDE I open the PHP script and add some breakpoints, I then open the latest.html and I click on the debug button. It launches the HTML page in a local webserver running at; http://127.0.0.1:8000/3i/latest.html I then fill out the form and submit at which point the debugger tells me the JS Debugger has terminated but it doesn't stop at my break points. I've had a good read around and I can't find anything which helps me, which makes me think it's something pretty easy and I'm being a bit dumb.

• How to identify deadlock conditions in a third-party application?

  - by Imhotep is Invisible

  I am using a third-party application to handle batch CD audio extraction via multiple FireWire attached devices, but the application frequently (though non-deterministically) hangs during the extraction. I suspect that the multithreaded application is deadlocking over some shared resource. The developer, however, suspects the problem lies elsewhere but is not addressing the problem at this time. I would like to be able to do some legwork on my end to a) prove the condition exists and b) ideally point him in the right direction. The problems: while I used to be a programmer, it's been awhile and I need to shake off the dust (last work I did was back in '99 and it was under Solaris, while the application runs under XP). Rather than there being a dearth of information online, there's almost too much to digest. Are there any suggested guides or tutorials that might help me get back up to speed sufficient enough to help identify and/or diagnose the deadlock, or are there tools or approaches that I should study up on to aid me in my task? Many thanks for all suggestions!

• How do I ensure my abstract class's function can only operate on extenders of the same type as the c

  - by incrediman

  For example, let's say this is my abstract class: abstract class A{ int x; int y; void foo(A fooMe); } ...and B and C are two classes which extend A. What I want is for B to only be able to call foo() on other Bs, and for C to only be able to call foo() on other Cs. But I want this to be out of the hands of the programmer who's extending my A class - that is, I want a way to ensure this functionality within As code alone. What can I do? (If possible) I'd like to avoid any hack or generics solution that's too messy - I still want foo to be able to be called like this, for example: B b=new B(); B bb=new B(); bb.foo(b);

• Easily digestible UI tips for developers

  - by David

  What are some key UI design tips that every developer should know? While there are a number of UI resources for developers (for example, Joel Spolsky's User Interface Design for Programmers), I'm interested in more of a bullet list that can be communicated in 1 to 2 pages. I'm interested in more tactical, day-to-day UI tips, as opposed to overarching UI design goals that would be covered in a UI design meeting (presumably attended by at least one person with a good UI sense). A collection of these tips might cover about 80% of the cases that an everyday programmer would come across.

• How to get into android phone without having to press any buttons

  - by user2961092

  I'm not a programmer, so I'm not sure what I'd needed to answer my question. I'm wondering if it's possible to program a way to half wake your cell phone screen without having to press any buttons or using the sensors. Like I've found you can do on the blackberry z10, you have an option to wake the screen by swiping up from a locked screen. I love android and will use it regardless, but I had to use a z10 for work for a while and stumbled upon that feature. It would be fantastic to have that feature with Android as hitting a power button can get annoying. Thanks in advance

• String Manipulation in Bash

  - by user348000

  Hello- I am a newbie in Bash and I am doing some string manipulation. I have the following file among other files in my directory: jdk-6u20-solaris-i586.sh I am doing the following to get jdk-6u20 in my script: myvar=`ls -la | awk '{print $9}' | egrep "i586" | cut -c1-8` echo $myvar but now I want to convert jdk-6u20 to jdk1.6.0_20. I can't seem to figure out how to do it. It must be as generic as possible. For example if I had jdk-6u25, I should be able to convert it at the same way to jdk1.6.0_25 so on and so forth Any suggestions?

• Keep row of datagridview clicked by user selected

  - by user367509

  Hi All, I need the snipped code in C# to mantain selected the row from a datagridview after that row is double clicked. Right now I'm displaying data from a dataset and the selection mode is FullRowSelect. Any way to set this? There are two scenarios to deal with: 1) Everytime the timer ticks the selected row always go to the first row of datagridview. 2) Once a row is clicked, it is selected but after the timer ticks the selected row goes to the first one. Thanks for your help! A newbie programmer

• Explode URL Query String Issue

  - by Ian McAbee

  PHP newbie here.. I am trying to create a function where the user is redirected back to the previous page after adding an item to their cart. However, when they are redirected back with the code below it leaves a duplicate of the directory (ie. example.com/catalog/garden-tools/garden-tools function custom_add_to_cart_redirect() { $_SERVER['REQUEST_URI_PATH'] = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH); $url = explode('/', rtrim($_SERVER['REQUEST_URI_PATH'], '/')); return $url[3]; } A print_r reveals the following: Array ( [0] => [1] => thefarmshop [2] => catalog [3] => garden-tools [4] => gardening-glove ) What could the issue be?

• What do I need to learn to make a website that can make a text file?

  - by lala

  I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

• How do I "propagate" my VS2008 Data Sources window with a LINQ query table?

  - by Kent S. Clarkson

  I´m (professionally) creating a SQL Server database client by using Visual Studio 2008, C# - Windows Form(s). And I´m using all the built in stuff, provided by my friend VS Studio, dragging and dropping, creating SQL query tables in DataSet.xsd, and so on... I like that. But! I would like to try out LINQ, as I would like to have something that to me is more intuitive than pure SQL... And (here comes the newbie-problem to be solved)! I don´t know where to put the LINQ code to make a table "pop up" in the Data Sources window - meaning I´m completely stuck! How should I do it?

• Lightweight open source CMS - current situation

  - by patrikas

  Hello, It happened that I need to pick up PHP based open source CMS. I did a small research and found many candidates. CMS made simple seems to be right choice, but I am not sure what's the current state, I know it was widely used time ago. I need it to be fully compliant with web standarts, lightweight (especially interface). It needs to be as simple as possible - basically just style and page content editing (news, maybe some image gallery) is enough. Sure content and style have to be separated from each other since content will be edited by non-programmer. One of the main goals is SEO so I'd like it to have friendly URLs. I think CMSes like Joomla, Drupal and Wordpress are too big for this project. Are there any recommendations ?

• Is it possible to take a half done web application that has been started using VB.NET and continue u

  - by John ClearZ

  A guy came to me there recently with a half done web app that has been created using VB.NET, nothing major, just a normal site. His original programmer couldn't continue so he wants me to finish it. Problem is I don't program using VB.NET nor have I any intention of learning it for a project this small. Usually I would run from something like this but I need the cash. Should I take the project and continue it using C# or just leave it. Has anyone had a similar experience and how did it turn out.

• Getting automatic matching brace in vim

  - by Bob

  I spend WAY to much time fumbling around because vim doesn't handle closing braces like most IDEs do. Here's what I want to happen: type this: if( whatever ) { <CR> where <CR> mean hit the enter key and get this: if( whatever ) { | } where | is the position of the cursor. It's what Eclipse does. It's what Visual Studio does. And it's what I want Vim to do. I've seen a few plugins, tried a few, and none of them seem to give me this behavior. Surely I can't be the first programmer to want this.

• How to deal with a coworker who keeps asking instead of searching herself?

  - by mafutrct

  I'm lucky enough to share a room with 3 other people at work. One of them, a senior programmer who's very talkative in general, tends to ask me various questions throughout the day. While some of them are surely ' legitimate', many questions could have been answered by putting in just slightly more search effort on their part. I really don't mind be asked stuff, and I can also cope with beginner questions, but this is seriously interrupting my flow. I clearly remember Joel talking about how private offices increase productivity because they prevent too easy questions from being asked. How should I deal with this situation? Getting a private office is out of the question, sadly. It's difficult to approach him directly, and he blissfully ignored the slight hints I tried to give.

• TDD, Unit Test and architectural changes

  - by Leandro

  I'm writing an RPC middleware in C++. I have a class named RPCClientProxy that contains a socket client inside: class RPCClientProxy { ... private: Socket* pSocket; ... } The constructor: RPCClientProxy::RPCClientProxy(host, port) { pSocket = new Socket(host, port); } As you can see, I don't need to tell the user that I have a socket inside. Although, to make unit tests for my proxies it would be necessary to create mocks for sockets and pass them to the proxies, and to do so I must use a setter or pass a factory to the sockets in the proxies's constructors. My question: According to TDD, is it acceptable to do it ONLY because the tests? As you can see, these changes would change the way the library is used by a programmer.

• Programming DataEntry&Forms: Population of Official Common Data Lists

  - by rlb.usa

  As a programmer of data-entry forms of all kinds, I often find myself making fields for things like Country and State. Consider: Perhaps a list the 50 United States names is an easy thing to find (does one include DC?) , but the countries are not. Nearly every site you find has a differing list with all of the political goings on over the years, and they become outdated quickly. What's the best practice regarding population of these kinds of lists? Is there an official list somewhere that one uses to populate these kinds of formal/official fields? Where do you get this data from, when it's not exactly specified in the specs?

• ruby on rails sub directory inside in the 'Views' main directory

  - by Kum

  Hello, am a newbie in ruby on rails and am stuck with a simple problem of routing. I have my controller 'sub' and the 'Views' folder containing the add,edit,new erb files. In my routes file, i have 'map.resources :subs'. Until now, everything is fine. Problem: I moved the add,edit,new erb files into a subfolder called 'admin' inside the 'Views' main directory. I have no idea how to call those erb files from that 'admin' subdir. By default, it is looking for /app/views/subs/index.html.erb, and i want it to look in /app/views/subs/admin/index.html.erb Please can anyone tell me how to do this. Many many thanks

• Rails Routes Mappings

  - by rdasxy

  I'm a rails newbie, and I have a controller called resource_links that I've mapped to resources: resources :resources, :as => :resource_links, :controller => :resource_links And this works (basically /resources works as /resource_links). However, trying to go to /resources/tags does not work. To get around this, I added more mappings as: match 'resource_links/tag/:tag(.:format)' => 'resource_links#tag', :via => :get, :as => 'resource_links_tagged', :constraints => {:tag => /.*/} match 'resource_links/tags' => 'resource_links#tags', :via => :get, :as => 'resource_links_tags' Is there any way I can get /resources/tags to be mapped to /resource_links/tag?

• Stacking multiple slideshows using Jquery

  Hi, JQuery newbie here! I'm having difficulty stacking more than one slideshow with each it's own individual controls. The one slideshow works just fine. However, when I add another slideshow I lose the controls and title for that one. link: http://dl.dropbox.com/u/1466448/numbered/stack.html I read on other related posts about using a unique ID for each slideshow but I have very limited experience in jquery to understand that approach. Any help would be greatly appreciated. Thanks! -Thai

• Why do I have to give an identifier?

  - by Knowing me knowing you

  In code: try { System.out.print(fromClient.readLine()); } catch(IOException )//LINE 1 { System.err.println("Error while trying to read from Client"); } In code line marked as LINE 1 compiler forces me to give an identifier even though I'm not using it. Why this unnatural constrain? And then if I type an identifier I'm getting warning that identifier isn't used. It just doesn't make sense to me, forcing a programmer to do something unnecesarry and surplus. And after me someone will revise this code and will be wondering if I didn't use this variable on purpouse or I just forgot. So in order to avoid that I have to write additional comment explaining why I do not use variable which is unnecessary in my code. Thanks

• I need guidance in building my first C# project

  - by grokker

  Hi I'm a PHP developer and I have some experience with Java. I'm trying to learn C# and my first project would be a program that starts the timer on a PC by clicking a button on another PC in the network. The problem is, I don't know where to start? What do I need to read up on? The OS for both PCs is Windows XP so they're desktop apps. I'd appreciate any help from you C# gurus. I hope my start as a C# programmer would be successful. Thank you!

• OSGI bundle (or service)- how to register for a given time period?

  - by Alec

  Hello, all! Search did not give me a hint, how can i behave with the following situation: I'd love to have 2 OSGI implementations of the same interface: one is regular, the other should work (be active/present/whatever) on the given time period (f.e for Christmas weeks :)) The main goal is to call the same interface without specifying any flags/properties/without manual switching of ranking. Application should somehow switch implementation for this special period, doing another/regular job before and after :) I'm a newbie, maybe i do not completely understand OSGI concept somewhere, sorry for that of give me a hint or link, sorry for my English.
