• How can I setup a svn subdomain so I can checkin/out without using svn+ssh?

  - by Martin

  I have a svn repository on my hosting account at ~/repository/. At the moment I have to create ssh keys to my server for users to checkin/out from the repository using a command like "svn+ssh://domain.com/project1/trunk". This is fine when there were 2 of us using the repository but now I have other people that might be doing work on the server that I cannot fully trust, hence I cannot give them ssh keys as then they will have access to my entire server. I would like to setup access to my svn repository via a subdomain e.g. svn.domain.com, so that users can checkin/out from this location using a command like: "svn co http://svn.domain.com/project1/trunk" - without using ssh. Can this be done and how? This should also help me solve my other issue of managing which users have access to which svn projects. Thanks for any help in advance!

• a problem in socket programing in perl

  - by isu

  I write this code : #!/usr/local/bin/perl use strict; use LWP::UserAgent; my $ua = new LWP::UserAgent(agent => 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.5) Gecko/20060719 Firefox/1.5.0.5'); $ua->proxy([qw(http https)] => 'http://203.185.28.228:1080' #that is just socks:port); my $response = $ua->get("http://www.google.com"); print $response->code,' ', $response->message,"\n"; but when i execute it i get this error: 500 Can't connect to 203.185.28.228:1080 (connect: timeout) what am i going to do ?

• selenium cannot find element with class in IE

  - by Rob

  I'm using selenium_client with cucumber, webrat + IE As you'd expect, Firefox works fine. I've tried the following: selenium.is_visible("css=#flash .flash_notice") selenium.is_visible("xpath=//*[@id='flash']/*[@class='flash_notice]") selenium.is_visible("xpath=//*[@id='flash']/*[contains(@class,'flash_notice]')") both cannot find the element. I think it must be something to do with IE, looking closer at the html selenium returns from IE... It looks like this: <UL id=flash> <LI className=flash_notice>Deleted</LI> </UL> Notice IE returns the class attribute as className, is this confusing selenium? How can I get round this so that I can use the same statement for selenium using IE and Firefox Just to confuse us even more, this example works, confirming its something to do with checking the class attribute selenium.is_visible("xpath=//*[@id='flash']/*[. =\'Deleted\']")

• What are the advantages of learning Go?

  - by Pangea

  What is so unique about Go? Over the 11 years of my career I've learnt Pascal, C, C++, COBOL and then Java. I always felt that going from C to C++ to Java was a incremental and value added progression. Now I see a proliferation of functional programming languages and I understand the benefit of learning few of them (like actors in scala etc). Now I was going through the Go programming language and was wondering why would I want to learn this? Is this going to simplify how I have been writing the code? What are its use cases? How can I make a case to promote it in my team? What is the next programming language that a Java team that builds business applications like us can benefit from? Appreciate your comments on this.

• Is a "Confirm Email" input good practice when user changes email address?

  - by dibson

  My organization has a form to allow users to update their email address with us. It's suggested that we have two input boxes for email: the second as an email confirmation. I always copy/paste my email address when faced with the confirmation. I'm assuming most of our users are not so savvy. Regardless, is this considered a good practice? I can't stand it personally, but I also realize it probably isn't meant for me. If someone screws up their email, they can't login, and they must call to sort things out.

• Database schema publishing with SQL Server 2005/2008

  - by Marconline

  Hi everybody, I've a question for you. We have built a software that has a single database for each customer. These databases are managed by SQL Server 2008. Now the problem is that when we build our software we, sometimes, need to change something on the schema (like adding table, modifying existing ones etc) and migrate these updates on all the customers' databases. Now this task is accomplished by hand: we generate update scripts and then, using T-SQL, we update each database. This is ok for a small set of customer, but we are now becoming bigger and bigger and we really don't know how to face it. We found Wizardby and it seems interesting, but quite difficult for us to learn in this exact moment. Do you have any other trick? Thanks a lot, Marco

• Why Microsoft not provide for C# a static Win32 class with the most native functions and structures

  - by Oleg

  Everybody who used P/Invoke of Windows API knows a long list of declarations of static functions with attributes like [DllImport ("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)] The declaration of structures copied from Windows headers like WinNT.h or from web sites like www.pinvoke.net take also a lot of place in our programs. Why we all have to spend our time for this? Why Microsoft not give us a simple way to include a line like in old unmanaged programs #include <windows.h> and we would be have access to a static class Native with all or the most Windows functions and structures inside?

• is PHP itself transforming into a framework?

  - by Elzo Valugi

  At the beginning PHP was a scripting language. But after the introduction and improvement of OOP I see more and more objects added to the core. They started with SPL which grew a lot, now we have DOMDocument family, DateTime family which should be part of PECL, Pear or Zend Framework or implemented by each one of us. Shouldn't be php only for build-in functions and all these objects passed to something else? Example. DateTime class is part of the core and I see it very similar with Zend_Date.

• What is it about Fibonacci numbers?

  - by Ian Bishop

  Fibonacci numbers have become a popular introduction to recursion for Computer Science students and there's a strong argument that they persist within nature. For these reasons, many of us are familiar with them. They also exist within Computer Science elsewhere too; in surprisingly efficient data structures and algorithms based upon the sequence. There are two main examples that come to mind: Fibonacci heaps which have better amortized running time than binomial heaps. Fibonacci search which shares O(log N) running time with binary search on an ordered array. Is there some special property of these numbers that gives them an advantage over other numerical sequences? Is it a density quality? What other possible applications could they have? It seems strange to me as there are many natural number sequences that occur in other recursive problems, but I've never seen a Catalan heap.

• Explain DLL Dependencies to a lay person

  - by wheaties

  This follows from a previous posting I made about lack of a clean test machine for software installations. I'm doing a bad job of explaining how DLL dependencies work and how some machines might not have the right libraries at the time of installation. The problem is that it's being viewed as a defect with the build process. I'm trying to educate the higher ups that it's not the build process per se but rather the installation process which is to blame. Here's a quote from my boss relating subcontractor work to our work to put it into perspective: I'm not a software person. All I see is that when they hand something to us it just works but when we hand something to the client there's all sorts of problems. There must be something wrong with how you're building the code. It's very easy to see how someone who is smart (scarily smart) could come to the wrong conclusion. So how would you explain the whole DLL dependency issue?

• I/O Asynchronous Completion

  - by lockedscope

  In the following, it is said that an I/O handle must be associated with the thread pool but i could not find where in the given example an handle is associated with the thread. Which function or code helps to bind the file handle in that example? Using asynchronous I/O completion events, a thread from the thread pool processes data only when the data is received, and once the data has been processed, the thread returns to the thread pool. To make an asynchronous I/O call, an operating-system I/O handle must be associated with the thread pool and a callback method must be specified. When the I/O operation completes, a thread from the thread pool invokes the callback method. http://msdn.microsoft.com/en-us/library/aa720215(VS.71).aspx

• What are the advantages of a distributed version control for a team that is effectively never distri

  - by Luke CK

  When working remotely, our team only has access to our source code by remote desktop into our office PCs so we never really work in offline mode. Does a distributed version control system like Mercurial or Git still give us advantages over our current centralized Subversion set up? If so, what are they? Are there any drawbacks or pitfalls? I've read in numerous places that shifting to distributed version control requires a change in thinking. Can someone explain what needs to change in this regard?

• Cannot create a VSPackage for Custom Editor in Visual Studio 2010

  - by user310291

  I followed the tutorial here http://msdn.microsoft.com/en-us/vstudio/Video/bb735001 which is for VS2005. I am on VS2010. After the Wizard finished, it says A project of same name is already opened in the solution. What's the matter? I tried several times changing the name of the vspackage to be sure but always same result. Update: I tried in Visual Studio 2008 and it doesn't occur so it's really a bug in VS2010 ! Did someone try ?

• Facebook javascript in address bar, possible to replicate?

  - by DoMx

  This is my first experience with stackoverflow and I'm afraid my question asks of a lot for a first. I was looking at this thread: http://stackoverflow.com/questions/2634159/javascrypt-in-the-adress-bar-is-this-malicious and as you will see SLaks has very kindly deobfuscated the javascript and left us with what appears as the Javascript behind the automatic facebook invite code. As I'm fairly new to javascript, I was wondering, what other components were needed to get this code to work? You of course have the functions there and they are called by the obfuscated javascript but how exactly? Would it be possible to replicate this on a page of my own using the information available or is there more to this script I am missing? I am willing to financially assist somebody who could compile a solution for me. Thank you in advance.

• Is it possible to center an image on both axis inside a div?

  - by Noor

  I have a script that loads in a div with images running jQuery Cycle Lite Plugin. I got the tip that I could us the "after" function in that plugin to make changes to the picture each time the image is refreshed. So I wrote this: $("#display div").css({ margin: "0 auto", "text-align": "center", }); The html built like this: <div id="display"> <div id="slideshow1"> <img ... /> </div> </div> This isn't working, whats wrong? ( this is supposed to center it horizontally, i need to center it vertically to )..

• Geocoding service for a startup?

  - by Sologoub

  I'm working on an idea for a service that uses geocoded data (lat/lng) form a US address. Google maps API v3 has been awesome, until I read the terms of service and acceptable uses a little closer. The problem is that the terms seem to prohibit use of the maps API for any commercial use where the site is not freely accessibly to the public, such as a subscription based service. The alternative offered is Google Maps API Premier, but at $10,000 per year minimum, it's just not possible at this time. Same goes for services offered by Yahoo! and MS - initial fees are small for enterprises, but for a very early stage startup (not even a finished prototype yet!) it's just not doable. Geocoding process needs to be real-time and volume would be very small - user would enter address at setup time and only update it if needed. Any help is greatly appreciated!

• What do we need for flash 10 development?

  - by user246114

  Hi, I'm looking to do some development in flash 10, specifically for the new file api (reading/writing files on the user's local machine). What do I need to develop for flash 10, just Flash cs4?: http://tryit.adobe.com/us/cs4/flash/c/?sdid=ETJMX& or is there some other ide? All I'm really interested in doing is: Make a small swf file which reads a file on the user's machine I will host it in an html file When file read is done, I just want to send its contents as a string to a javascript function for further processing. Not sure if I can get away with the free adobe air thing for this? I need it to run in a webpage but I don't intend to do any more development outside of the above, Thanks

• I want to use VI-like commands in Web Browser?

  - by Frank

  I love VI and I'm looking for a plugin of some sort that would allow me to input text in my browser (preferably Firefox or Chrome) using VI commands. It would save me an immense amount of time and at the same time when writing long emails. Can anyone think of any plugins that would allow me to do this? I was hopeful with Vimperator (https://addons.mozilla.org/en-US/firefox/addon/4891) but after installing it, I realized that it didn't do the one VI think I wanted to do: create or edit a text box with VI commands. It just allowed me to do Browser commands and scrolling in VI-style.

• Given a string of red and blue balls, find min number of swaps to club the colors together

  - by efficiencyIsBliss

  We are given a string of the form: RBBR, where R - red and B - blue. We need to find the minimum number of swaps required in order to club the colors together. In the above case that answer would be 1 to get RRBB or BBRR. I feel like an algorithm to sort a partially sorted array would be useful here since a simple sort would give us the number of swaps, but we want the minimum number of swaps. Any ideas? This is allegedly a Microsoft interview question according to this.

• Simplest way of creating java next/previous buttons

  - by Holly

  I know that when creating buttons, like next and previous, that the code can be somewhat long to get those buttons to function. My professor gave us this example to create the next button: private void jbtnNext_Click() { JOptionPane.showMessageDialog(null, "Next" ,"Button Pressed", JOptionPane.INFORMATION_MESSAGE); try { if (rset.next()) { fillTextFields(false); }else{ //Display result in a dialog box JOptionPane.showMessageDialog(null, "Not found"); } } catch (SQLException ex) { ex.printStackTrace(); } } Though, I do not really understand how that short and simple if statement is what makes the next button function. I see that the fillTextFields(false) uses a boolean value and that you need to initialize that boolean value in the beginning of the code I believe. I had put private fillTextFields boolean = false; but this does not seem to be right... I'm just hoping someone could explain it better. Thanks :)

• What is the preferred sql server column definition to use for a LINQ to SQL Version property?

  - by Mike Two

  We are using the IsVersion property on the ColumnAttribute on a property in a LINQ to SQL class for optimistic concurrency checks. What should the column definition be in the database? Currently we are using version_number int NOT NULL IDENTITY (1, 1) Do we need Identity? Can we get LINQ to SQL to update the version number for us? The only issue with Identity is that every row has a different number. We'd like to see the number increment by 1 when the row is updated.

• Flex 4.5 - to long build process

  - by Idob

  We are developing an app using flex 4.5. The app runs just fine (no performance issues at all) but it takes us forever to compile and build it. A minor change, like just add a comment or press enter in an mxml file and rebuild takes about 3 minutes. You just cant work that way. It is a large project with about 1300 files. We also use Parsley as IOC container and a beat of cairngorm navigation. We also use Maven (Flex mojos) but I am talking about a normal eclipse build (Ctrl + B). We separated some of the code to a different SWC and all of our graphics are stored in a different resource SWF. Please, Do you have any suggestions? Regards, Ido

• Dropdown in Access 2007 parameter query. Why not working

  - by waanders

  Hello, I want a Access parameter query to ask an user for a value (a location in this case). When I type [Enter location] in the Criteria field it works fine: I get a dialog box (Enter Parameter Value) with a textbox and my text (Enter Location). So far, so good. This works (the result also). But now I want a dropdown/combobox (instead of a textbox ) for the user to pick a location. I made a form and type Forms![Form1]![CmbLocation] in the Criteria field. Like this: http://office.microsoft.com/en-us/access/HA011170771033.aspx But I still get a textbox (with the reference as textlabel). What am I doing wrong? Has anybody any advice?
