• How to upgrade a 1.4.3 TortoiseSVN created repository to 1.6.x?

  - by SiegeX

  A few years ago we deployed TortoiseSVN 1.4.3 to our software development team and we used this client to create a repository on a share point. We are now looking at upgrading to the latest 1.6.x version of TortoiseSVN. I had hoped this would be transparent as the additional features and modifications will all be client-side. For the most part this is true except for a very important feature -- merging. When I try to merge a feature branch back into truck I get a "Merge tracking not supported error." So now the question becomes, how does one upgrade a 1.4.3 TortoiseSVN created repo to be compatible with the latest 1.6.x version of TortoiseSVN? As a follow up question, if we were to successfully upgrade the repo such that the 1.6.x client works flawlessly, will we still be backwards compatible with a 1.4.x client?

• What was the most surprising failure of your 'Engineer's intuition'?

  - by Bubba88

  Hi! This may seem as an open-ended question but I'll surely accept the most impressive and upvoted answer ;) Basically, I could describe my own case - I just fail 5 times a day with my intuition cause very frequently I can be just not up-to-the-speed with my requirements/manager/team/etc. and I just have to make code quickly - that's why proper formalization in many cases stands aside. I want to gather some experience of yours - what was the most epic failure when you did rely on you implicit reasoning/intuitive knowledge/immediate perception etc. of course everything you describe should be related to programming/computers. It's mostly just to measure the danger of using that 'it's obvious..' words. I've made it com. wiki to be properly transformed after gathering enough views count. Thank you!

• How do I properly load the jQuery fullcalendar plugin in a hidden div

  - by Jens Alm

  I'm using the jQuery tools tabs to divide my page into tabs. One of those tabs contain a jQuery Fullcalendar. Because I load JavaScript last in the page for speed and to avoid flash of unstyled content, I hide the initially unseen tabs using display:none. When doing this, the fullcalendar doesn't render properly. It shows the proper buttons, but until I press the today-button, no calendar is shown. If I allow it to render into a visible div, it displays properly. I can work around this using the tab-select events to render the calendar or by moving the calendar and tab scripts to the head, but I'd rather if there was a more proper solution.

• Continuous integration with .net and svn

  - by stiank81

  We're currently not applying the automated building and testing of continous integration in our project. We haven't bothered this far as we're only 2 developers working on it, but even with a team of 2 I still think it would be valuable to use continous integration and get a confirmation that our builds don't break or tests start failing. We're using .Net with C# and WPF. We have created Python-scripts for building the application - using MSbuild - and for running all tests. Our source is in SVN. What would be the best approach to apply continous integration with this setup? What tool should we get? It should be one which doesn't require alot of setup. Simple procedures to get started and little maintanance is a must.

• Looking for a jQuery Developer [closed]

  - by Caroline Pires

  Hi, We are currently looking for a jquery developer, experienced specifically with flowplayer, to integrate a video player into our web application prototype. The player interface is being built in html and has to be wired to the flash player using the flowplayer jquery library. We also hope to be able to overlay some html elements on top of the video. A few extra jquery tools (scrollable and overlay) should be integrated with our page design as well. We are under a tight deadline and need to start work on this ASAP. For any further details please contact me on: [email protected] Thank you, Caroline

• Customizing scrollable plugin with prevpage and nextpage over the image? (see mock up)

  - by aaandre

  Hi, I am implementing a scrollable for a portfolio gallery. (scrollable = scrollable plugin from http://flowplayer.org/tools/index.html ) There will be one item visible at a time. By default, scrollable positions the prev/next buttons outside of the image area and clicking on the current image advances the scrollable content. I would like to have the prev/next render within the image area. I would like to have an image caption appear when mousing over the lower part of the image. Mock-up: http://i303.photobucket.com/albums/nn160/upstagephoto/mockups/scrollable_mockup.jpg Any ideas on how to achieve one or both of these? Thank you!

• Looking for an elegant way to store one-to-many relationship in coredata when order is important

  - by Eric Schweichler

  I've been trying to come up with a way to solve my problem, but every solution I can think of is messy and makes me want to retch. I have a one-to-many relationship, consisting of a Team object that can have many Member objects. When I built my data model using Xcode, I was given the default NSSet in which to store the member objects, Unfortunately Sets are not ordered and I need to preserve the order of the Member objects and I need to know if there are empty spaces between Members. I thought of Using an NSArray in place of the NSSet and creating a dummy Member object in my data store that I could use to mark vacant a spot between to Member objects, but that solution really feels like too much of a hack to me. Since I'll always have to filter out this dummy Member from any queries. An NSDictionary would be perfect as I could store the Member object references and their positions as Object-Key pairs, (taking care of both order and vacancies) but apparently CoreData does not support NSDictionary. Has anyone had a similar need, and devised a simple solution?

• Automated testing of a website for IE7 javascript errors?

  - by Andreas Bonini

  This week I decided to add a new element to a javascript array by copying a similar one from a previous line; unfortunately I forgot to remove the comma so the end result was something like var a = [1, 2, 3,]. The code went live late Friday afternoon just before everyone left for the week-end, and it completely broke everything in Internet Explorer 7 (and lower I assume) since it's such a great browser. Since there was no one to read emails (week-end) it went unnoticed for quite a while, and I really don't want something like this to happen again (especially in my code).. This is not the first of weird IE7 problems; I was wondering if there was a way to automatically test key pages looking for javascript or css errors, or really anything that IE8 would output in its new console in development tools. If there isn't, what do you usually do? You test the website after every change with all the browsers you support? (Something I'll do from now, at least for IE, if there is no way to run automated tests)

• Integration Testing an Entire *Existing* Application (w/ automatic execution of test suite)

  - by Ev

  Hi there, I have just joined a team working on an existing Java web app. I have been tasked with creating an automated integration test suite that should run when developers commit to our continuous integration server (TeamCity), which automatically deploys to our staging server - so really the tests will be run against our staging web app server. I have read a lot of stuff about automated integration testing with frameworks like Watir, Selenium and RWebSpec. I have created tests in all of these and while I prefer Watir, I am open to anything. The thing that hasn't become clear to me is how to create an entire test suite for an application, and how to have that suite execute in it's entirety upon execution of some script. I can happily create individual tests of varying complexity, but there is a gap in my knowledge about how to tie everything together into something useful. Does anyone have any advice on how to create a full test suite and have it execute automatically? Thanks!

• sproutcore or cappucino for web app development?

  - by swami

  I recently found out about the sproutcore and capuccino frameworks for web app development as proper MVC approach to creating Desktop-like applications. As far as I could understand, the main difference between the two frameworks is that Cappucino abstracts away the HTML+CSS+Javascript to Objective-J - a new programming language developed be the creators of Capuccino that adds OO capabilities to Javascript, whereas Sproutcore uses HTML5,CSS,Javascript. After lots of pondering, I thought it's probably best to go with technologies we know, so I downloaded the Sproutcore tools and did the tutorials, and I have to say I was very impressed. Just the kind of thing I was looking for, for organizing a complex web app. However, I just stumbled across the following link: http://charlesjolley.sys-con.com/node/1341228 in which Charles Jolley (the creator of Sproutcore) syas that he's tired of waiting for the HTML5 and ECMAScript5 specs to get finalized, and announces that from version 1.1 onwards they will be switching to Objective-J ! So now the question is - what will actually differentiate Sproutcore and Capuccino - and which one should I choose now? Kind Regards Swami

• Release build in MVS 2010 professional v/s express for C

  - by yCalleecharan

  Hi, recently I discovered that "executing" a C program as a release build instead of a debug build optimizes the code and makes it run much faster. This is accessed through project properties configuration manager menu. I would like to know if this feature is the same in the professional version and the express edition of MVS 2010 in terms of speed optimization. I have the express edition. Also, I would like to know if C programs run with the same speed as in both the professional and express editions. I understand that the professional edition has many "software" tools for the serious programmer. Thanks a lot..

• How to debug a process using Visual Studio?

  - by Ian Boyd

  If an application† crashes: i hit "Debug" and Visual Studio is my currently registered Just-In-Time (JIT) debugger: Visual Studio appears, but there's no way to debug anything: i do not see any disassembly. i do not see any symbols i do not see reconstructed source code from reflection i do not see any registers the call stack is empty Other JIT debugger products are able to show disassembly, but they are either command-line based (Debugging Tools for Windows), or do not support symbols (OllyDbg, Delphi). Additionally, my question is about debugging using Visual Studio, since i already have it installed, and is already my registered JIT. How do you debug a program using Visual Studio? Alternatively: has anyone written a graphical debugger that supports the Microsoft symbol server? † not, necessarily, written in Visual Studio Edit: Changes title to process rather than application, since the latter somehow implies "my application."

• Mongrel with Ruby 1.9.

  - by JussiR

  When starting the server, I get this strange error after updating to Ruby 1.9: " [BUG] cross-thread violation on rb_gc() ruby 1.8.6 (2008-08-11) [i386-mswin32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. " My mongrel version is 1.1.6, which should be compatible with Ruby 1.9. I also still have the Ruby 1.8.6 installation, so i assume that for some reason mongrel tries to access that and kills ruby? My rails version is 2.3.4, in case it matters.

• dynamics CRM performance question

  - by tomo

  Hello Dynamics CRM gurus :) My boss asked me to do a research on available CMSes on market because cms we are using currently is rather a mess. For me as a .NET developer it would be great to choose and implement Dynamics CRM because of extensibility and perfect integration with .NET environment and well-known tools. All marketing blahbla sounds great but I'd like to know about common DISADVANTAGES, ISSUES concerning this system. The most important is how it is performing in a company with about 150 concurrent and very active users. I heard that is't really slow comparing to competitors system. Thanks in advance Best regards, Tomasz.

• First time unit testing (in silverlight)

  - by Jakob

  Hi I've searched some other posts, but most of them assumed that people knew what they were doing in their unit testing, and frankly I don't. I see the idea behind unit testing, and I'm coding an silverlight application much in the blind right now, and I'd like to write some unit tests to kind of be sure I'm on the right path. I'd like to be able to use the SL4 vs 2010 silverlight unit test project template, to keep it simple and not use external tools. So what I need an answer for are questions like: what are the methods of unit testing? what are the differences between unit tests, and automated unit tests? How do I meaningfully unit test in silverlight? What should I be aware of while unit testing (in silverlight) ? Also should I implement some kind of IRepository pattern in my silverlight app to make unit testing easier?

• Using Delphi or FFMpeg to create a movie from image sequence

  - by Hein du Plessis

  Hi all My Delphi app has created a squence called frame_001.png to frame_100.png. I need that to be compiled into a movie clip. I think perhaps the easiest is to call ffmpeg from the command line, according to their documentation: For creating a video from many images: ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi The syntax foo-%03d.jpeg specifies to use a decimal number composed of three digits padded with zeroes to express the sequence number. It is the same syntax supported by the C printf function, but only formats accepting a normal integer are suitable. From: http://ffmpeg.org/ffmpeg-doc.html#SEC5 However my files are (lossless) png format, so I have to convert using imagemagick first. My command line is now: ffmpeg.exe -f image2 -i c:\temp\wentelreader\frame_%05d.jpg -r 12 foo.avi But then I get the error: [image2 @ 0x133a7d0]Could not find codec parameters (Video: mjpeg) c:\temp\wentelreader\Frame_C:\VID2EVA\Tools\Mencoder\wentel.bat5d.jpg: could not find codec parameters What am I doing wrong? Alternatively can this be done easily with Delphi?

• Database Modeling - Either/Or in Many-to-Many

  - by EkoostikMartin

  I have an either/or type of situation in a many-to-many relationship I'm trying to model. So I have these tables: Message ---- *MessageID MessageText Employee ---- *EmployeeID EmployeeName Team ---- *TeamID TeamName MessageTarget ---- MessageID EmployeeID (nullable) TeamID (nullable) So, a Message can have either a list of Employees, or a list of Teams as a MessageTarget. Is the MessageTarget table I have above the best way to implement this relationship? What constraints can I place on the MessageTarget effectively? How should I create a primary key on MessageTarget table?

• What are some good books on software testing/quality?

  - by mjh2007

  I'm looking for a good book on software quality. It would be helpful if the book covered: The software development process (requirements, design, coding, testing, maintenance) Testing roles (who performs each step in the process) Testing methods (white box and black box) Testing levels (unit testing, integration testing, etc) Testing process (Agile, waterfall, spiral) Testing tools (simulators, fixtures, and reporting software) Testing of embedded systems The goal here is to find an easy to read book that summarizes the best practices for ensuring software quality in an embedded system. It seems most texts cover the testing of application software where it is simpler to generate automated test cases or run a debugger. A book that provided solutions for improving quality in a system where the tests must be performed manually and therefore minimized would be ideal.

• turning on Greasemonkey live editing

  - by Delirium tremens

  On Firefox, I click Tools, Addons, Extensions, Greasemonkey, Options, select my user script, click Edit, change the source code, reload one of the included pages, but the script is the unchanged version. On User Scripts, logged in, I click my username, Script Management, my script's name, Admin, Edit Code Online, change the source code, click save, the link to the install page, install and the script is the changed version. How did you turn on Live Editing? While following Greasemonkey tutorials, this feature is not working... Are you going to use the "works on my computer" excuse? Should this be on the Stack Overflow sister site Super User?

• Setting up a web developer lab for learning purposes

  - by Saleh Al-Abbas

  I'm not a developer by profession. Therefore, I'm not exposed to real world technical problems that face professional developers. I read/heard about web farms, integration between different systems, load balancing ... etc. Therefore, I was wondering if there are ways for the individual developer to create an environment that simulates real world situations with minimal number of machines like: web farms & caching simulating many users accessing your website (Pressure tests?) Performance load balancing anything you think I should consider. By the way, I have a server machine and 1 PC. and I don't mind investing in tools and software. PS. I'm using Microsoft technologies for development but I hope this is not a limiting factor. Thanks

• how to deploy wcf-service on iis 6.0

  - by Walter

  I have IIS 6.0 on Windows Server 2003. I installed .Net 3.5 and 4 beta 2. "Normal" asp things are working (perfect). But when I try to navigate to my service (/myServer/MyService.svc) I got a 404. Page not found. To be exact, I got a 404 2 "Web service extension lockdown policy prevents this request." I used ServiceModelReg.exe /ia to make sure that the extension I known and I checked the configuration using: admin-Tools, iis, home-tab, configuration, executable-box, and there: extension: .svc, path: c:\windows\microsoft.net\framework\v4.0.210... verbs: all verbs So everything seems ok. But I still get a 404-2

• How can I prevent users from taking screenshots of my application window?

  - by Midday

  What are some methods to prevent screenshots from being taken, if any? I've considered setting the "Print Screen" button as a hotkey, which makes the window fuzzy. However, there would be the problem of other 3rd party screenshot tools. How can I prevent their use? Why would I want such a thing? The idea is to create a chat client which you can't share the chatted information with others, not by copy & paste nor by print screen... Looking for general ideas or suggestions rather than actual code.

• OutOfMemoryException, stack size is huge, large number of threads

  - by Captain Comic

  Hello, I was profiling my .net windows service. I was trying to discover OutOfMemoryException and discovered that my stack size is huge and is growing because the the number of threads keeps growing. Each thread gets 1024 KB on Windows x64 machine. Thus when my app has 754 threads the stack size would be 772 MB. The problem for me is that i don't know where these thread come from. Initially my app has a very limited number of threads and they keep growing with time. I have two suspicions - either these threads are created by WCF or by database connection. My application uses both WCF and datasets. Also I tried to profile my app in Ants do Trace i can see large number of System.ServiceModel.Channels.ClientReliableDuplexSessionChannel and this number is increasing with time. I can see thousands of these objects created. So what I want to know is who is creating threads (tools to discover, profilers) and if it is WCF who is creating these threads.

• From interpeted to native code: "dynamic" languages compiler support

  - by Daniel

  First, I am aware that dynamic languages is a term used mainly by a vendor; I am using it just to have a container word to include languages like Perl (a favorite of mine), Python, Tcl, Ruby, PHP and so on. They are interpreted but I am interested here to refer to languages featuring strong capability to support the programmer efficiency and the support for typical constructs of modern interpreted languages My question is: there are dynamic languages can be compiled efficiently in native executable code - typically for Windows platforms? Which ones? Maybe using some third part ad-hoc tools? I am not talking about huge executables carrying with them a full interpreter or some similar tricks nor some smart module able to include its own dependances or some required modules, but a honest, straight, standard, solid executable code. If not, there is some technical reason inhibiting the availability of such a best-of-both-world feature? Thanks! Daniel
