• Why browser doesnt recognize jquery when <script src="...jquery.js> is on a html page served by Goo

  - by indiehacker

  jquery.js source code is not being recognised by browser using my page.html served by Google App Engine as a http:some_request to the SDK, BUT when I load the exact same page.html into the browser directly from my local hard drive as jquery.js all works OK, it is recognized, so I know my path is OK.... I don't understand? In the header of my page.html I have the following: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js" type="text/javascript"></script> I also tried without success in the header this: <script src="/static/jquery.js" type="text/javascript"></script> I am working along with the examples in the [Jquery tutorial][1]. I am sure there is something simple I dont understand about how .html pages served to the browser from app engine interact differently with the browser than what I normally would expect....but I frustratingly just cant get it.....everything else I have with my app engine app is working fine......would love some help so i can move forward....

• Are you using Virtual Machine as your primary development enviroment?

  - by Click Ok

  Recently I have purchased a notebook that cames with Windows Home Basic (that don't have with ASP.Net/IIS. I thought in upgrade the Windows version to one with ASP.Net/IIS, but I thought in another possibility: I have an Hard Disk Case with a 360Gb HD. I thought in create a virtual machine with Windows Ultimate (installing too ASP.Net, IIS and Visual Studio 2008) in this HD Case, then I can access my "development enviroment" in any computer that I will work on (my desktop machine and my notebook). But I was worried about the performance. I don't have experience working in Virtual Machines (I use it just to quick compatibility tests)... Are you using Virtual Machine as your primary development enviroment? What your finds? ==================== Thanks for your answers! It really did help me! I would like to know too about portability ie.: the virtual machine that I created in my laptop will work in the desktop? I will need re-activate Windows?

• Storing cvs data for further manipulation using Ruby

  - by ischnura

  I am dealing with a csv file that has some customer information (email, name, address, amount, [shopping_list: item 1, item 2]). I would like work with the data and produce some labels for printing... as well as to gather some extra information (total amounts, total items 1...) My main concern is to find the appropriate structure to store the data in ruby for future manipulation. For now I have thought about the following possibilities: multidimensional arrays: pretty simple to build, but pretty hard to access the data in a beautiful ruby way. hashes: having the email as key, and storing the information in different hashes (one hash for name, another hash for address, another hash for shopping list...) (getting the cvs data in to a Database and working with the data from ruby??) I would really appreciate your advice and guidance!!

• How can I impersonate the current user with IronPython?

  - by Ryan Montgomery

  I am trying to manage an IIS7 installation remotely using the Microsoft.Web.Administration library. I'm doing this in IronPython: import Microsoft.Web.Administration from Microsoft.Web.Administration import ServerManager manager = ServerManager.OpenRemote("RemoteServerName") for site in manager.Sites: print "Site: %(site)s" % { 'site' : site.Name } On the last line as it attempts to communicate with the remote server I get the following error: Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from machine devdealernetsvr failed due to the following error: 80070005. My research into the error lead me to believe that I do not have the proper credentials against the remote machine and so I would like to impersonate a user that does. I was hard pressed to find a way to do this with IronPython. Any help is much appreciated.

• How do I generate (and label) a random integer with python 3.2?

  - by An hero

  Okay, so I'm admittedly a newbie to programming, but I can't determine how to get python v3.2 to generate a random positive integer between parameters I've given it. Just so you can understand the context, I'm trying to create a guessing-game where the user inputs parameters (say 1 to 50), and the computer generates a random number between the given numbers. The user would then have to guess the value that the computer has chosen. I've searched long and hard, but all of the solutions I can find only tell one how to get earlier versions of python to generate a random integer. As near as I can tell, v.3.2 changed how to generate and label a random integer. Anyone know how to do this? Thanks!

• Performance problems when loading local JSON via <script> elements in IE8

  - by Jens Bannmann

  I have a web page with some JS scripts that needs to work locally, e.g. from hard disk or a CD-ROM. The scripts load JSON data from files by inserting <script> tags. This worked fine in IE6, but now in IE8 it takes an enormous amount of time: it went from "instantly" to 3-10 seconds. The main data file is 45KB large. How can I solve this? I would switch from <script> tags to another method of loading JSON (ideally involving the new native JSON parser), but it seems locally loaded content cannot access the XMLHttpRequest object. Any ideas?

• Is EF4 "Code Only" ready for production use?

  - by Tommy Jakobsen

  I've been looking at the new Entity Framework 4 Code Only features, and I really like them. But I'm having a hard time finding good resource on the feature. Everything seems to be spread around blongs here and there, so this make me wonder if it's ready to be used for a serious project? What do you think? Is it ready for production use or should I use the more traditional approach (EDMX designer, POCO objects)? Also, I would like to know if there are any features that Code Only does not support yet, compared to the EDMX designer? What do you think about the Code Only feature? Is it "mature" yet? Thank you.

• Integrate ClickOnce update in a setup

  - by Erick

  As recent decision in my team we decided to deploy a software we develop for some time now in ClickOnce. Previously it was deployed with a merge module in a setup project. We had in mind to actually deploy the ClickOnce setup/updater in the web server setup. The problem here would not exactly to integrate it but to make sure to limit the human work to integrate it. Normally I guess it would be necessary to "add - file" and select the folder containing the setup.exe + publish.htm + application files + .application, but I fear that for each time we publish a new version to the hard drive we have to update the setup project as well. Would someone have some insight to help that ? (especially to not have to add the program_[version] folder inside application files that is created each time a new publish is done).

• Accessing XAML Object Variables in XAML

  - by Asryael

  So, what I'm trying to do is access my Form's width and/or height to use in a storyboard. Essentially, I have a Translate Transform animation to slide what are essentially two pages. The animation works fine with hard coded From/To variables, however I need to use soft variables that enable the animation to start from the left/right of my form no matter what size it is. <Storyboard x:Key="SlideLeftToRight" TargetProperty="RenderTransform.(TranslateTransform.X)" AccelerationRatio=".4" DecelerationRatio=".4"> <DoubleAnimation Storyboard.TargetName="PageViewer" Duration="0:0:0.6" From="WindowWidth" To="0"/> <DoubleAnimation Storyboard.TargetName="BorderVisual" Duration="0:0:0.6" From="0" To="NegativeWindowWidth"/> </Storyboard> However, I have no idea how to do so. Any help is greatly appreciated. EDIT: I'm guessing it has something to do with: From="{Binding Width, Source=MainWindow}" However, when I attempt this, I don't know how to make it negative.

• Custom Django tag & jQuery

  - by pocoa

  I'm new to Django. Today I created some Django custom tags which is not that hard. But now I wonder what is the best way to include some jQuery or some Javascript code packed into my custom tag definition. What is the regular way to include a custom library into my code? For example: {% faceboxify item %} So assume that it'll create a specific HTML output for Facebox plugin. I just want to learn some elegant way to import this plugin into my code. I want the above definition to be enough for all functionality. Is there any way to do it? I couldn't find any example. Maybe I'm missing something.. Thank you.

• DLL response is too slow in Visual Studio [Resolved]

  - by magsto

  I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger? I found a setting that resolved my issue: Project Properties Debug Enable Debuggers select "Enable unmanaged code debugging". Now the DLL communication flowed smoothly. The DLL I use is a middleware between my app and a USB device. There is no Debug/Release version of the DLL.

• Passing javascript form variables into jQuery function not working

  - by Chase

  I am trying to pass some JavaScript variables that I have assigned to form variables into a query string used by a jQuery plug in called fancybox. If I hard code in the string that I want lightbox works great, however I need it to pass some form values in there to make it work as desire. <script type="text/javascript"> $(document).ready(function(){ var item = document.itemFinder.item; var zip = document.itemFinder.zip; var radius = document.itemFinder.radius; var dataString = "item=" + item + "&zip=" + zip + "&radius=" + radius; $("#various3").fancybox({ ajax : { type : "POST", data : dataString}, 'scrolling' : 'auto', 'overlayOpacity' : '0' } ); }); </script> What am I doing wrong?

• wordpress filters documentation? Trying to understand add_filter()

  - by Chris J. Lee

  I read over the documentation several times and have been having a hard time trying to figure out what is going on with the function. I'm more and more confused after looking at the documentation, looking over the source code as well. add_filter($tag, $hook, $priority, $args); it seems to me the new function extends the parent function. What puzzle's me is what parts of the hook becomes overridden. in some examples in the documentation i see that some variables are replaced with the $args in your new $tag. I almost understood it all here: http://www.andrewnacin.com/2010/05/18/rethinking-template-tags-in-plugins/ but then i couldn't figure out how you pass arguments and which eventually get overriden. thanks in advance.

• Why people do not like OOP? [closed]

  - by Gabriel Šcerbák

  I do not understand why people choose C++ over Smalltalk in past and why Java over Python or Ruby. What is it that ties people so much to the procedural programming and makes it so difficult to go "all the way" to object oriented programming? What makes OOP hard? Should not objects be an abstraction which is easier to grasp for people, i.e. a more natural one than procedures? Is education the problem (because people tend to learn procedural programming before object oriented)?

• Anchors within the document and their position.

  - by Jose Vega

  On the following website, www.josecvega.com, I have a navigation bar with years that link to sections on that same page. Unfortunately it is not working they way I hoped, when the user selects a year it moves to the section of the page, but puts that section on the top of the page. I have a fixed div on the top of the page that covers the sections and prevents it from properly displaying. What can I do for this to work? It hard to explain my situation, but it can be seen by going to www.josecvega.com and clicking one of the years.

• Find by include nil object error in rails

  - by SpyrosP

  I've been trying hard to solve this problem but i really don't know what is happening. I have this small piece of code : DiscoveredLocation.find_by_user_id(user.id, :include => [:boss_kills]) The models are : DiscoveredLocation(id, user_id, boss_location_id) BossKill(user_id, monster_id) and associations : Monster belongs_to :boss_location Monster has_many :boss_kills BossKill belongs_to :user BossKill belongs_to :monster DiscoveredLocation belongs_to :user DiscoveredLocation belongs_to :boss_location DiscoveredLocation has_many :monsters, :through => :boss_location DiscoveredLocation has_many :boss_kills, :through => :monsters When i executed the find_by i get this error : NoMethodError in BossesController#index You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each If i change the include option to any other model, like :monster, it works great. I'm pretty much owned by this problem :P. Maybe somebody can help me ? :)

• Planning a skillset for a fallback career [closed]

  - by Davy Kavanagh

  I'm not too certain this is a SO question, but I didn't think it belonged in meta either. Long story short, I am bioinformatics researcher. I like to code, it's my favourite part of the job. I have been thinking for a while that if academia is not kind to me, I might seek a career in software development. My current contract is for three years and I would like to spend some time over the next 3 three years learning and practicing software development as possible. Python seems like a popular language and it what I mostly use to do things for me, but I am also in heavy use of R. So my main question is: Are python and R good things to be learning with a sotfware dev goal in mind, and if so, is there any particular type of programming or software that might be useful to have experience with. Hard questions to answer I know, but I thought I would get the answer from people who are in the know. Cheers, Davy.

• Why does OSX document atoi/atof as not being threadsafe?

  - by Larry Gritz

  I understand that strtol and strtof are preferred to atoi/atof, since the former detect errors, and also strtol is much more flexible than atoi when it comes to non-base-10. But I'm still curious about something: 'man atoi' (or atof) on OS X (though not on Linux!) mentions that atoi/atof are not threadsafe. I frankly have a hard time imagining a possible implementation of atoi or atof that would not be threadsafe. Does anybody know why the man page says this? Are these functions actually unsafe on OS X or any other platform? And if they are, why on earth wouldn't the library just define atoi in terms of strtol, and therefore be safe?

• Are there any OSGi web service / SOAP clients out there?

  - by James Carr

  I'm looking for any webservice client that can be run inside an OSGi container and connect to a simple web service using SOAP, doesn't sound so hard does it? Oh, and it has to work under Java 1.5, so the JRE jax-ws wont be present. The problem is I've tried a few solutions now, and although each solution works in standard Java using it from within OSGi doesn't. the springsource JAX-WS bundles seem to have dependency issues the CXF bundles get me as far as calling the service, but then can seem to find the stub methods in the proxy Is there anyone out there who has successfully created an OSGi webservice client?

• How are a session identifiers generated?

  - by Asaf R

  Most web applications depend on some kind of session with the user (for instance, to retain login status). The session id is kept as a cookie in the user's browser and sent with every request. To make it hard to guess the next user's session these session-ids need to be sparse and somewhat random. The also have to be unique. The question is - how to efficiently generate session ids that are sparse and unique? This question has a good answer for unique random numbers, but it seems not scalable for a large range of numbers, simply because the array will end up taking a lot of memory.

• Visual Studio 2008 awful performance

  - by Nima

  Hi, I have ported a piece of C++ code, that works out of core, from Linux(Ubuntu) to Windows(Vista) and I realized that it works about 50times slower on VS2008! I removed all the out of core parts and now I just have a piece of code that has nothing to do with the hard disk. I set compiler parameters to O2 in Project Properties but still get about 10times slower than g++ in linux! Does anybody have an idea why it is this much slower under VS? I really appreciate any kind of hint! Thanks,

• Is nothing truly ever deleted in git?

  - by allenskd

  I'm currently learning git, usually I'm a bit skeptic of VCS since I have a hard time getting used to them. I deleted a branch called "experimental" with some tmp files, I saw the files removed in my working directory so I scratched my head and wondered if this is normal, can I bring it back in case I need it again, etc. I found the SHA making the commit of the tmp files and recreated the branch with the provided sha and saw it again with all the files and their current content. Everything I do in the working directory can be reverted once I commit it? Might seem like a silly question to many people, but it kinda intrigues me so I want to know the limits
