• having a test debug app and a released debug app side by side

  - by Tristan

  Yo! When I download my app from the iStore, the latest test version installed to my phone gets over written. Does anyone know how to have two versions of the same app side by side? On a test project, I edited the build settings so that "realease" and "debug" have different product names. This seemed to solve my problem, however when I try this same trick on my actual project, the two overwrite each other again. Does anyone have a recommendation? I don't mind how it's done. Thanks! Tristan

• IE Specific JavaScript

  - by Banderdash

  This feels like a stupid question, or one that could be answered with a little trial and error and some Googleing--but I assure you I have tried both and several ideas and am not getting the results I'm after. Here are my JS includes for a site: <!-- JavaScript --> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script> <script type="text/javascript" src="js/accordian.js"></script> <!--[if IE 7]><script type="text/javascript" src="js/ie-accordian.js"></script><![endif]--> I'm simply trying to deliver the ie-accordian.js to IE 7 and accordian.js to all other browsers. Just not having any luck keeping IE 7 from using accordian.js as opposed to the one created especially for it. Any thoughts?

• How Do I Prevent a XSS Cross-Site Scripting Attack When Using jQueryUI Autocomplete

  - by theschmitzer

  I am checking for XSS vulnerabilities in a web application I am developing. This Rails app uses the h method to sanitize HTML it generates. It does, however, make use of the jQueryUI autocomplete widget (new in latest release), where I don't have control over the generated HTML, and I see tags are not getting escaped there. The data fed to autocomplete is retrieved through a JSON request immediately before display. I Possibilities: 1) Autocomplete has an option to sanitize I don't know about 2) There is an easy way to do this in jQuery I don't know about 3) There is an easy way to do this in a Rails controller I don't know about (where I can't use the h method) 4) Disallow < symbol in the model Sugestions?

• Interviewing - convincing young interviewers that my experience matters [closed]

  - by ritu

  As requested, I split this question from a two part question I asked at http://stackoverflow.com/questions/2482071/modern-web-development-general-question My question is how do i convince the young programmers who interview me that my years of system programming experience, MFC, Win32 programming are still relevant and I should not be automatically rejected because I don't know the differences between Drupal and <pick your technology>. It seems like I can ask a dozen question that these guys won't be able to answer but somehow because I don't know the latest fad counts against me. I do read, but if you don't use what you read in your daily work, you will never have expert knowledge of it. So bottom line: is the only way for me to take a .NET or Java job is for me to start at the bottom all over?

• ruby_threadptr_data_type error

  - by declan

  I'm starting up a new rails app with the latest version of rails (3.1.3). When I try to invoke the rails generator things get a little rough. First I fixed this bug, and now I'm getting this one /home/declan/.rvm/gems/ruby-1.9.3-p0@lcm/gems/ruby-debug-base19-0.11.25/lib/ruby- debug-base.rb:1:in `require': /home/declan/.rvm/gems/ruby-1.9.3-p0@lcm/gems/ruby- debug-base19-0.11.25/lib/ruby_debug.so: undefined symbol: ruby_threadptr_data_type - /home/declan/.rvm/gems/ruby-1.9.3-p0@lcm/gems/ruby-debug-base19-0.11.25 /lib/ruby_debug.so (LoadError) from /home/declan/.rvm/gems/ruby-1.9.3-p0@lcm/gems/ruby-debug-base19-0.11.25/lib/ ruby-debug-base.rb:1:in `<top (required)>' There's a discussion about this going on here, but I can't make enough sense of it to get things to work.

• How do you keep a balance between working, training, health and family?

  - by Jim Burger

  One trend I see in the awesome developers I've met, is that they devote inordinate amounts of time to coding at the expense of (usually) their health. Personally, I also find it hard to motivate myself to keep healthy. Every now and again, I meet a fantastic coder who has it clocked; they are up to date with the latest dev news, have time to read about good programming practices, and to finish it off, have happy wives/husbands and families. How do you guys/gals manage it in the short 24 hours a day that we all have?

• RegexKitLite Runtime Crash

  - by Hasan Can Saral

  I'm overlaying the mapview and using RegexKitLite. I couldn't make it work. I've downloaded .m and .h files and added to the project. Also I tried, adding libicucore.dylib or libicucore.A.dlib or adding -licucore to other compiler flags field. Still getting the error: 2012-04-01 19:38:04.633 sennerdeysen[907:15803] -[__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x88b6a00 2012-04-01 19:38:04.634 sennerdeysen[907:15803] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x88b6a00' Any idea? Latest Xcode but the sdk is 4.3 Without ARC or anything else that iOS 5.0 SDK provides.

• Linq to Sql saying that item by 'Customer' already exists. Choose a different name.

  - by Anthony Potts

  I have been going round and round with a linq to sql file while using svn for quite some time. The latest is that my dbml file shows as having an error which states that An item named "Customer" already exists. Please choose a different name. And then it repeats that again. In fact, it says it for almost every object. What is my fix? I have tried renaming the one named Customer, but that didn't fix it. I don't know where to go to fix this. I went to the .dbml file and don't see any duplication, and I went to the .dbml.layout file and didn't see any duplication there either.

• Setting the content-type of requests performed by jQuery jqGrid

  - by Nigel

  I am using the latest version of jqGrid: 3.6.4 This seems like a simple problem (or at least it did before I spent a few hours on it): When the grid sends a request to the server (to a controller action), its content-type is always: application/x-www-form-urlencoded; charset=UTF-8 and I would like it to be: application/json; charset=utf-8 but I can find no way of setting the content-type (there is no contentType option as you would find on a $.ajax call for example). So just to clarify, I am not asking how to set the content-type on a jQuery server request, but specifically using jqGrid, which does not provide an obvious option for doing this. Thanks, Nigel.

• Extracting dates from html meta data in FAST-ESP

  - by Neil

  During document processing I want to extract all dates from html meta data and then identify the latest date which will be used to populate a date field (dtgeneric1). <meta name="OriginalPublicationDate" content="2010/04/21 12:06:36" /> <meta name="LastModificationDate" content="2010/04/22 14:10:16" /> + other non-date meta data Inspection using spy stages shows that our pipeline already adds meta_* attributes but the meta data names will be different across documents from different sources. #### ATTRIBUTE meta_originalpublicationdate <class 'docproc.DocumentAttributes.TextChunks'>: 2010/04/21 12:06:36 #### ATTRIBUTE meta_lastmodificationdate <class 'docproc.DocumentAttributes.TextChunks'>: 2010/04/22 14:10:16 + other non-date meta attributes Ideally we would like to pass all the meta_* attributes to a Python stage and use that to work out which are dates and which is the largest but there seems to be no way of specifying "all meta attributes" as input. Has anyone done something similar and can offer any advice on the best way to do this. Thanks Neil

• Installing Django/Python on IIS6

  - by Sohrab Hejazi

  We are currently installing the latest version of Django and Python on IIS6. We have followed the instructions on the following site: http://code.djangoproject.com/wiki/DjangoOnWindowsWithIISAndSQLServer We are receiving a 403 error when trying to access our Django application via the IIS server. We have verified the python installation on IIS6 and it is working properly. We have also verified the Django installation. Our application runs fine under the built-in Django server, but we are having difficulties getting it to run under IIS. We presume we could be getting errors from "Linking Django to PyISAPIe" section of the instructions provided on the link above. Thanks.

• ASP.NET MVC Best Implementation Practices

  - by RSolberg

  I've recently been asked to completely rewrite and redesign a web site and the owner of the company has stressed that he wants the site to be made with the latest and greatest technology available, but to avoid additional costs. As of right now, I'm torn between looking into a CMS implementation and writing a new implementation with MVC. The site is mainly brochure ware, but will need to allow the visitors to submit some data through forms. There are quite a few lists and content features that are dynamic and should be treated as such. Since ASP.NET MVC is new, I don't want to bastardize the implementation if I go that way... Any recommendations on best implementation practices for a MVC website? Also, has anyone had their MVC implementation hosted anywhere that they would recommend?

• Random blank pages on Safari when developing webapp

  - by Ali

  Hey guys, I've been experiencing a safari problem while building a web application. The screen goes completely blank (white) and refreshing won't help. Going to another page on the site gives the same problem. Then magically, after a little while, everything goes back to normal and pages are rendered correctly! This started happening around the same time that I SUSPECT my hosting automatically upgraded from PHP 5.2.x to 5.3 (all of a sudden, we got 'deprecated function' errors and the error settings and handling were unchanged) I also have to mention that this doesn't happen in our dev environment (PHP 5.2.9, Apache 2) Settings Safari 4.0.2 and the latest one (don't know the version) Server side: PHP 5.3, MySQL 5.0.90, Apache is cPanel Easy Apache v3.2.0 Does anyone know why this is happening at all, or how to fix it? I appreciate any help or pointers you might have. Thanks!

• iphone OS 3.1.3 requires snow leopard upgrade

  - by unsorted

  itunes asked me to upgrade my iphone's OS to 3.1.3, so I complied naively. then xcode told me that the latest iphone OS version it could support was 3.1.2. So I went to download a new version from https://developer.apple.com/iphone/index.action#downloads, xcode 3.2.2 with iphone SDK. but when i went to install that, i was told I needed snow leopard 10.6.2 or later. so I'm just making sure that I am not misinterpreting anything when I say that, given that it is impossible to downgrade iphone OS versions without jailbreaking, I need to install a new version of the OS just so I can resume testing apps on my iphone?

• PHP array : simple question about multidimensional array

  - by Tristan

  Hello, i've got a SQL query which returns multiple rows, and i have : $data = array( "nom" => $row['nom'] , "prix" => $row['rapport'], "average" => "$moyenne_ge" ); which is perfect, but only if my query returns one row. i tried that : $data = array(); $data[$row['nom']]["nom"] = $row['nom'] ; ... $data[$row['nom']]['average'] = "$moyenne_ge"; in order to have : $data[brand1][nom] = brand1 $data[brand1][average] = 150$ $data[brand2][nom] = brand2 $data[brand2][average] = 20$ ... but when i do : json_encode($data) i only have the latest JSON object instead of all JSON object from my request as if my array has only one brand instead of 10. I guess i did something stupid somewhere. Thanks for your help

• Should I put my output files in source control?

  - by sebastiaan

  I've been asked to put every single file in my project under source control, including the database file (not the schema, the complete file). This seems wrong to me, but I can't explain it. Every resource I find about source control tells me not to put generated output files in a source control system. And I understand, it's not "source" files. However, I've been presented with the following reasoning: Who cares? We have plenty of bandwidth. I don't mind having to resolve a conflict each time I get the latest revision, it's just one click It's so much more convenient than having to think about good ignore files Also, if I have to add an external DLL file in the bin folder now, I can't forget to put it in source control, as the bin folder is not being ignored now. The simple solution for the last bullet-point is to add the file in a libraries folder and reference it from the project. Please explain if and why putting generated output files under source control is wrong.

• PHP File Exists Always False

  - by Joe

  I have a case where file_exists() is always returning false. My latest attempt was to just test to see if it would return true for $_SERVER["SCRIPT_FILENAME"] and then return the value of the path if it couldn't find the file which it does. The path while not necessarily relevant to solving the problem is: /Users/joe/Workspace/720/app/webroot/index.php I have obviously verified that the file is there, and am not even sure how it couldn't be there since php is serving it up. I should mention this is on an install of OS X Snow Leopard running PHP 5.3.0. Any ideas would be fantastic. CODE SAMPLE: if (!file_exists($_SERVER["SCRIPT_FILENAME"])) $errors[] = 'Cant find:'. $_SERVER["SCRIPT_FILENAME"];

• How do you tell if your migrations are up to date with migratordotnet?

  - by Lance Fisher

  I'm using migratordotnet to manage my database migrations. I'm running them on application setup like this, but I would also like to check on application startup that the migrations are up to date, and provide the option to migrate to latest. How do I tell if there are available migrations that need to be applied? I see that I can get the migrations that were applied like this var asm = Assembly.GetAssembly(typeof(Migration_0001)); var migrator = new Migrator.Migrator("SqlServer", setupInfo.DatabaseConnectionString, asm); var applied = migrator.AppliedMigrations; I like to do something like this: var available = migrator.AvailableMigrations; //this property does not exist.

• learning the Lower levels of computing

  - by Ben

  I am a software developer with four years experience in .Net development, I always like to keep up to date with the latest technologies (.net related normally) being released and love learning them. I didn't however go to university and learnt all I know through helpful colleagues, .Net courses, the internet and good old books. I feel that I am a good developer, but without learning the lower levels of a computer as you would in the first year of a computer related Uni course, I get lost when talking to people about a lot of more technical lower level computing. Is there a book(s) that anyone could recommend, that would cover the lower levels of what is going on when I click "Run" in Visual Studio? I feel out of my depth when my boss says to me "Thats running in the CPU cache" or "you're limited by disk reads there", and would like to feel more confident when talking about how the hardware talks to each other (CPU to RAM etc). Apologise if thats a vague question, or has been asked before (i did check and couldn't find anything on here that answers my question).

• how should I order my divs?

  - by aslum

  Here's the basic layout of a page I'm working on: What would be the best/easiest way to order the divs? C may or may not be visible (it's a news alert that only displays when there is news). A = Header, B = Menu, E&F = standard content columns, D = latest blog post. I'm thinking ABCEFD might make the most sense, but I could also see ABCDEF. Either of those should be fairly easy to do right using floats... is there a better way? Maybe put CEF inside a "middle column" div?

• Has there been a Firefox update recently?

  - by Rob Nicholson

  Trying again to ask a PROGRAMMING question because of the over-zealous closing off of what is equally a programming question before allowing the poster to clarify. The latest version of Firefox (v3.6.3) is breaking websites, mine included. I make heavy use of the Infragistic NetAdvantage controls. These, because of their heavy JavaScript reliance and occasional lack of quality control, tend to suffer through browser updates sometimes requiring a hotfix. So the question is... has there been a Firefox release recently that has either introduced a bug, tightening up of some standard, bug fix which might have broken a previous workaround (often the case) etc? I'm guessing around JavaScript but that's a guess hence the reason for asking a group of programmers...

• What is a robust jQuery Rich Text Editor with image upload capabilities?

  - by thinkswan

  I know this question has been asked countless times, but answers are mixed, so I thought I'd test the waters and see what the latest verdict is out in the development community. I need a [preferably jQuery] rich text editor plugin that simply attaches itself to <textarea> elements and supports image uploads. It doesn't need to be too advanced. Just alignment, bold, italic, styles and image support. I tried CKEditor (along with CKFinder for image uploads), but it just has too many features and is too heavy for what I need. This is going to be used for simple webpage editing.

• Microsoft Expression Web 3 clipboard bug

  - by Ghostrider

  There seems to be a rather annoying bug in MS Expression Web 3 (or perhaps an incompatibility with something else I have installed). Quite often HTML code editor would refuse to copy things into clipboard. You select some text, press Ctrl-C, Ctrl-Insert or use context menu and nothing happens. Then in 10..15 seconds it would start working again... Then again it would not work. It's rather annoying. Does anyone else have such a problem or knows how to fix it? I'm running Microsoft Expression Web 3 Service Pack 1 Version 3.0.3813.0 on Windows 7 Ultimate x64 with all latest updates and patches. I have Russian keyboard layout installed. Other than that my system is pretty much plain vanilla.

• How do you separate the template of a blog block in Drupal?

  - by Ralph

  Hi, In Drupal, I created a block using views. This block contains the latest blog entries. I've placed this on a specific page to display it as an archive. Now, as for the blog itself (for example when one of them is clicked), A blog template for it depends on node-blog.tpl.php. My problem is, when I style node-blog.tpl.php, the block I created for the archives (as it displays on the page) gets affected. For example if I add TEST on node-blog.tpl.php, I will also get that on the block for every entry. I think it's because it is associated to a blog entry? What I want is to have node-blog styled "alone" when blog entries are viewed individually and not get the other entries on the blocks on the archive page be affected. How should I do this?
