• Running sites on "localhost" is extremeley slow.

  - by seanxe

  Hello all, Having real trouble using my local host to test sites. It runs extremely slow! Sometimes up to a minute to load a page. I'm using firefox and the sites i'm testing run fine on other developers in my office local machines/ on the production server. I've gone through the normal things :- Disabled IPv6 Not running in debug mood Put the site in the highest app pool (High Isolated) on IIS 6. Taking of firewalls etc. The problem only seems to occur when hitting pages which contain some form of .net code in the code-behind. Appreciate that this a little bit of a vague topic / stab in the dark but would appreciate any sort of advice - it's horrible waiting a minute each refresh to try out a change! Cheers, Sean.

• How to change the default Help browser for VS2010?

  - by Scott Bilas

  Visual Studio 2010 changed the help system to run a little daemon and launch the system default web browser to view it. I'm using Firefox for my system browser but would like to use Chrome for VS help. Is there an option to change the Help browser that I'm not seeing in Tools|Options? If not, is there a workaround or registry setting to do this? As a backup I've been using H3Viewer but I'd like to be able to get context-sensitive F1 help from within the VS IDE.

• Is there a server side API for Team Foundation Server?

  - by Ralph Shillington

  It would seem there is precious little documentation on programming against a TFS 2010 instance. What bits I have found, have next to nothing in the case of documentation beyond barebones listing of client access classes and their members, most likely autogenerated from the code comments. As I'm interested in building a silverlight client against TFS, I will need access to a server side API. Ideally the silverlight app will talk to my server (mainly for work items) and my server will in turn talk to the TFS server for the goods. Where is the doumentation (if any) for this kind of TFS integration?

• designing multi module J2EE application

  - by user728947

  Might be my question is abstract or out of context, but i am asking here since i have little idea how this happens. I am wondering how big application/ platform break down there application in to multiple module and how they able to manage modules dependencies. For example in some E-commerce application they tend to break down it in various modules like pricing,promotions,shipping.import/export and many more. when we develop those application we hardly think about the underlying modules and how they have been designed to provides functionalists. Most of those module are not web-applications but are standalone module and not deployed in the web-app as jar files. can any one help me to understand how they break up things or is there any standard way to do this.any help/resources to get insight will really be helpful

• Teaching a kid to type in order to start programming

  - by at

  My 5 year old wants to start programming, but he doesn't yet know how to type without looking for each letter 1 at a time. I know it's going to frustrate him to go so slow because of his typing speed. And it's not going to be fun looking for all the letters constantly... So what's the best way to get him to type fast? Clearly he'll need to type a lot of punctuation like semicolons, colons and symbols. So his little hands will have to get used to spreading over the keyboard... I did some google searches and found some very poor looking apps that focused on the letters.

• Opinions sought on the best way to organise classes in PHP

  - by jax

  I am pretty much set on using the Java package naming convention of com.website.app.whatever but am unsure about the best way of doing this in PHP. Option 1: Create a directory structure com/ mysite/ myapp/ encryption/ PublicKeyGenerator.class.php Cipher.class.php Xml/ XmlHelper.class.php XmlResponse.class.php Now this is how Java does it, it uses the folders to organize the heirarchy. This is however a little clumsy in PHP because there is no native support for it and when you move things around you break all includes. Option 2 Name classes using a periods for the package, therefore sames are just like in Java but can all be in the same directory making __autoload a breeze. classes/ com.mysite.myapp.encription.PublicKeyGenerator.class.php com.mysite.myapp.encription.Cipher.class.php com.mysite.myapp.xml.XmlHelper.class.php com.mysite.myapp.xml.XmlResponse.class.php The only real disadvantage here is that all the classes are in a single folder which might be confusing for large projects. Opinions sought, which is the best or are there other even better options?

• Rails 3 routes and using GET to create clean URLs?

  - by Hard-Boiled Wonderland

  I am a little confused with the routes in Rails 3 as I am just starting to learn the language. I have a form generated here: <%= form_tag towns_path, :method => "get" do %> <%= label_tag :name, "Search for:" %> <%= text_field_tag :name, params[:name] %> <%= submit_tag "Search" %> <% end %> Then in my routes: get "towns/autocomplete_town_name" get "home/autocomplete_town_name" match 'towns' => 'towns#index' match 'towns/:name' => 'towns#index' resources :towns, :module => "town" resources :businesses, :module => "business" root :to => "home#index" So why when submitting the form do I get the URL: /towns?utf8=?&name=townname&commit=Search So the question is how do I make that url into a clean url like: /towns/townname Thanks, Andrew

• Conditionally required jsf validation in a4j form

  - by volothamp

  Hello, I'm having a little problem with using conditionally evaluated expression in jsf/a4j Here's my code <a4j:form> <h:inputText id="id1" value="#{mybean.myvalue}" size="1" required="#{not mybean.condition}" rendered="#{not mybean.condition}" requiredMessage="Put a number in here" /> <h:selectBooleanCheckbox value="#{mybean.condition}"> <a4j:support event="onclick" reRender="id1"/> </h:selectBooleanCheckbox> <a4j:commandButton action="#{mybean.myaction}" value="Do something" /> </a4j:form> The boolean checkbox conditionally enable/disable the validation. This doesn't work: the a4j:commandButton simply skip the validation. Thanks.

• can rails send data to browser chunk by chunk?

  - by Nik

  Hello all, I have a very large dataset (100,000) to be display, but any browser I tried that on including chrome 5 dev, it make them choke for dozens of seconds (win7 64bit, 4gb, 256gb ssd, c2duo 2.4ghertz). I did a little experiment by some_controller.rb def show @data = (1..100000).to_a end show.html.erb <% @data.each do |d| % <%= d.to_s % <% end% as simple as that it chokes the browsers. I know browsers were never built for this, so I thought to let the data come in chunk by chunk, I guess 2000 per chunk is reasonable, but I wouldn't want to make 50 requests each time this view is called, any ideas? It doesn't have to be chunk by chunk if it can be sent all at once. Best,

• jQuery colorbox plugin isn't loading inline content

  - by Summer

  Hi, I'm trying to use the jQuery colorbox plugin to show a little warning when a warning icon is clicked. Check out the problem: - Go to http://dev.imagineelection.com/browse/zip/10011 - Click on one of the warning icons (scroll down to see one). See how the colorbox that pops up is empty? I've tried to isolate the problem: - If you click "View Source" -- the div id="address-alert" is in there - If you click "View Generated Source" (for example, with Firefox Web Developer plugin) -- the div id="address-alert" has been taken out, but it has not been replaced inside the new div id="cboxCurrent" that colorbox has put at the top of the page The jQuery call I'm doing is: if (jQuery().colorbox) { $(".warning-class").colorbox({width:"50%", inline:true, href:"#address-alert"}); } What is going on? Why won't the inline content work?

• Jquery .html and .load

  - by Jack Pilowsky

  I'm trying to teach myself jQuery and I'm a little stomped with the load() method. I'm working on eBay listings. Yes, I know includes are not allowed on ebay. However, there is a workaround that has been around for a few years and ebay doesn't seem to be cracking down on it. var ebayItemID='xxxxxxxxxxxxxx'; // This is eBay code. I cannot edit it. <h1 id="title"> TO BE REPLACED</h1> $(document).ready(function(){ var link = "http://www.ebay.com/itm/" + ebayItemID + "?item=" + ebayItemID + &viewitem=&vxp=mtr"; var newTitle = $('#title').load(link + "#itemTitle"); $('#title').html(newTitle); }); What's the point of this. I want to show the item title on the description, but I want to do so dynamically,

• Dynamically reducing image dimension as well as image size in C#

  - by hanesjw

  I have an image gallery that is created using a repeater control. The repeater gets bound inside my code behind file to a table that contains various image paths. The images in my repeater are populated like this <img src='<%# Eval("PicturePath")' %>' height='200px' width='150px'/> (or something along those lines, I don't recall the exact syntax) The problem is sometimes the images themselves are massive so the load times are a little ridiculous. And populating a 150x200px image definitely should not require a 3MB file. Is there a way I can not only change the image dimensions, but shrink the file size down as well? Thanks!

• Creating Ruby applications for Windows.

  - by Omega

  I want to develop a Windows application. Honestly I care little about cross-platforms for now (but still would be good) I want to use Ruby, since it has quite a simple syntax and is so.. well, simple and easy to learn. My application is like a "game level creator", where you can design your own level and then run it with another application which is a "game level player" by reading the project file created by the creator app. You get the idea. Now, I got a new PC and is completely clean. Absolutely no trace of my old Ruby experiments and fails. First of all, I will need to choose a GUI platform for my Ruby application! Can you recommend me one? I have heard of Shoes and Tk, but want to know what you think.

• Which programming language is easiest to get a junior position in?

  - by markle976

  I do not have a CS degree but I have lots of intermediate experience with many languages (PHP, C#, Objective-C, Java, VBScript, Actionscript, Javascript, Ruby, etc), mostly freelance or pastime. I have a little experience with Linux (Ubuntu), and a decent bit with Windows. When I look at different languages I find that am interested in most (except maybe VB), but I am not sure what to focus on. So what would be the easiest language to get a job in? Java? PHP? Or would it be easier to get a job as a Junior DBA if I learned Oracle or SQL Server in my spare time?

• Why it is necessary to put comments on check-ins? [closed]

  - by Mik Kardash

  In fact, I always have something to put in when I perform a check-in of my code. However, the question I have is - Is it really so necessary? Does it help so much? How? From one point of view, comments can help you to keep track of changes performed with every check-in. Thus, I will be able to analyze the changes and identify a hypothetic problem a little bit quicker. On the other hand, it takes some time to write useful information into check-in. Is it worth it? What are the pros and cons of writing comments to every check-in? Is there any way to write "efficient" check-in comments?

• How to programmatically deactivate the AirPort?

  - by mystify

  I want to make a small utility to programmatically deactivate the AirPort of my mac. I have networking problems which couldnt be resolved by expensive experts. I need to deactivate and reactivate the mac AirPort once every half hour. So a little utility which does that automatically would be great. I think I wouldn't need an UI for this either. Just the most simple possible kind of application to automatically stop and start the AirPort. Maybe even apple automator code?

  I have had this problem for too long time: package-manager not working or very unstable, examples here. Now suppose my laptop has very little precious stuff.

• Really basic Django E-commerce? Where do I start

  - by Andrew

  I'm trying to set up a really basic e-commerce site with Django, and am trying to figure out the best place to start. I am relatively comfortable with the framework itself, but have never done any sort of e-commerce development in any language, so I want to learn about some best practices so I don't make any huge or obvious mistakes. I've looked at Satchmo, and even went as far as installing and playing around with it, but it looks like way more than I want. I basically want to show users a list of things, and let them click a button to buy one. No cart, no shipping, just click a button, connect with Authorize.net (or something similar) to do the transaction, and then display a confirmation page. Any suggestions or online tutorials people have found helpful? Even perhaps a tutorial in another language. Or maybe a really lightweight Django plugin that doesn't try to do everything like Satchmo? I've been coming up with very little so far. Thanks!

• Find the min max and average of one column of data in python

  - by user1440194

  I have a set of data that looks like this 201206040210 -3461.00000000 -8134.00000000 -4514.00000000 -4394.00000000 0 201206040211 -3580.00000000 -7967.00000000 -4614.00000000 -7876.00000000 0 201206040212 -3031.00000000 -9989.00000000 -9989.00000000 -3419.00000000 0 201206040213 -1199.00000000 -6961.00000000 -3798.00000000 -5822.00000000 0 201206040214 -2940.00000000 -5524.00000000 -5492.00000000 -3394.00000000 0 I want to take the second to last column and find the min, max, and average. Im a little confused on how to use split when the columns are delimited by a space and -. i Figure once i do that i can use min() and max function. I have written a shell script to do the same here #!/bin/ksh awk '{print substr($5,2);}' data' > /data1 sort -n data1 > data2 tail -1 data2 head -1 data2 awk '{sum+=$1} END {print "average = ",sum/NR}' data2 Im just not sure how to do this in python.

• Fix internal links in JS

  I just created a script which extracts the article out of a webpage via server-side JS. (If your interested: it's used for http://pipes.yahoo.com/fb55/expandr .) I just got a little problem with internal links. Some pages include links like: /subfolder/subpage.html What I would need to do is fixing them and setting there root, like this: protocol://secondlevel.firstlevel/subfolder/subpage.html I'm using E4X for processing the page. I don't want to show my current creepy try, it's buggy and slow. Does anybody have a solution for me?

• How can I change my code in Excel 2003 to allow me to paste to multiple cells?

  - by PikeCoAL

  Ran in to a little problem. If I try to paste to multiple cells that are in the range in the code below, I get a run time error 13, type mismatch. The cells in the range may have data other than X but I only want the hyperlink to appear if the cell contains X. It works fine if I just type an X in the cell or if I paste to one cell at a time. I will have times when I want to paste other text to mutiple cells in this range. Thanks to Remnant for his help on the original code. This one last hurdle will put me in the clear. Thx. Private Sub Worksheet_Change(ByVal Target As Range) Dim rangeLimit As Range Set rangeLimit = Range ("B9:B37,C9:C37,D9:D37,E9:E37,F9:F37,G9:G37,H9:H37,I9:I37,J9:J37,K9:K37,L9:L37,M9:M37") If Not Intersect(rangeLimit, Target) Is Nothing Then If Target = "x" Or Target = "X" Then Target.Hyperlinks.Add Anchor:=Target, Address:="", SubAddress:="Exceptions!A1", TextToDisplay:=Target.Value End If End If End Sub

• Grabbing Data From Controls In Code Behind

  - by MKell43

  Hopefully this is a pretty simple question for someone to answer. I have a drop down list control that I need to pull the value from in the code behind of the page, modify it and redisplay it. The modifying and redisplaying I've got no problem with, it's grabing the value from the drop down control. Examples in C# would be appreciated as this web app I've been handed is already coded that way. I'm pretty new to .Net so be gentle and I already did some searching via Google and a little bit on the site here, but couldn't find anything that stood out as being the direction to go in to do this.

• (Re)Enabling JavaScript debugger in IE7 with Visual Studio 2008

  Visual Studio 2008 comes with nice javascript debugging features. But I have played a little with NetBeans debugger wich has installed an ugly Script Debugger from Microsoft to my IE... Normally IE should ask what do I want to use for debugging, but now I can't start debugging with Visual Studio, the Script Debugger is started automatically... After uninstalling the Script Debugger I can't debug in IE at all. Even attaching to iexplore.exe process doesn't helps... Has installed the Script Debugger again... :((((( How can I get back my Visual Studio debugging working in IE again?

• Does cache absolute expiration guarantee that the cache is eliminated at the exact time?

  - by Fabio Milheiro

  I am using the HttpRuntime cache to store lists of objects and in our current project it was specified that the objects should be cached until midnight, so I am using DateTime.Today.AddHours(24) in order to set the absolute expiration date to midnight. For example, if today is May 26th, the absolute expiration time will be set to May 27th 0:00. But somehow, when I change the clock of my computer, the objects are still in cache. Should I wait a little (the CacheItemPriority is set to Normal)? Am I forgetting something? Thank you
