• How and where do you store your private work/source codes?

  - by Amir Rezaei

  I have worked as developer for over 10 years now. Over the time I have had my own small projects where I have developed tool/application and games. I have not found any robust solution to store my work. It’s always fun to get back to your code and see how you did before and how you would do it now. It’s just a work that is unfortunate to get lost. There are SVN solution such as Google’s Project Hosting. However I’m not interested in sharing my code or making it open source. Currently I’m hosting my own SVN server. So here comes my question. How and where do you store your private work/source codes? Requirements: Source code versioning Backup Prefers free

• Problem with MVC3 application

  - by Pravin Patil

  I am working on MVC3 application. I use entity framework, NInject, Fluent Validation and some more Nuget packages. I am using Tortoise SVN for versioning. Recently I changed the structure of my SVN repository, so my working copy of MVC3 app was moved to some different folder in the repository. Now when I checked out the copy from SVN, all the references that I had added through Nuget were lost(EF, NInject and rest nuget packages were showing yellow missing icon in references). This had happened to me prior to this also, when I tried to check out the app from svn to some other folder. I had to manually add all the references again through Nuget again. Am I doing anything wrong? Please guide. I hope I could explain my problem properly.

• Type dependencies vs directory structure

  - by paul

  Something I've been wondering about recently is how to organize types in directories/namespaces w.r.t. their dependencies. One method I've seen, which I believe is the recommendation for both Haskell and .NET (though I can't find the references for this at the moment), is: Type Type/ATypeThatUsesType Type/AnotherTypeThatUsesType My natural inclination, however, is to do the opposite: Type Type/ATypeUponWhichTypeDepends Type/AnotherTypeUponWhichTypeDepends Questions: Is my inclination bass-ackwards? Are there any major benefits/pitfalls of one over the other? Is it just something that depends on the application, e.g. whether you're building a library vs doing normal coding?

• Getting that buzz back?

  - by kyndigs

  I have been working in development for a good company for a while now since graduating from university, I really enjoy it and have some great fun in the office and enjoy everything I am doing. But recently I have lost that old buzz, I cant bring myself to code outside of work, a while back I could be outside of work and come up with a nice idea and go away and develop that idea, but I feel that buzz has gone, I still love developing and technology but I just cant find the energy to do it when I am not at work. Has anyone else gone through a phase like this? What did you do to combat it and get that energy and buzz back? Maybe I need a new tehcnology, or a holiday!

• Weird unexpected image compression on a web server running Apache on Ubuntu?

  - by Billy Bob Thornton

  I have a weird problem on my production web server running Apache on Ubuntu: it compresses my images thereby dramatically lowering their quality! Actually I have two virtual hosts running, each located in a different folder. Wether I display .gif images by navigating on the two sites, or acceding them directly by their url, their size and quality are invariably degraded. I tried with three different browsers: same problem. Using them on other sites on the Web: no problem. Of course I disabled mod_deflate on the server (which should not compress images anyway), but the phenomenon remains. On my local développement server, running the same configuration, everything is Ok. Now I'm completely lost! For the record, my configuration: Ubuntu 10.04, Apache 2, Php 5.

• 2D basic map system

  - by Cyril

  i'm currently coding a 2D game in Java, and I would like to have some clues on how-to build this system : the screen is moving on a grander map, for instance, the screen represent 800*600 units on a 100K*100K map. When you command your unit to go to another position, the screen move on this map AND when you move your mouse on a side or another of the screen, you move the screen on the map. Not sure that i'm clear, but we can retrieve this system in most RTS games (warcraft/starcraft for example). I'm currently using Slick 2D. Any idea ? Thanks.

• 12.04 Dual Monitor Configuration changes to "Mirrored" automatically

  - by Josef

  After installing 12.04 on my Samsung X120 Notebook (with Intel GMA 4500 internal graphics card) i have a Problem with the configuration off my 2nd monitor. Its a 22" with 1680 * 1050 Pixel connected via HDMI. I use the display configuration and set internal display=off and external display=main display. That works fine. After rebooting i still have that configuration, but after a while (often when i press a button on the keyboard), the configuration automatically changes to "Mirror Screen" and the internal display switches on. Both displays then have a bad resolution. When i do the manual display configuration again, everything is fine for the duration of that session. What could be the problem, that this display configuration gets lost / resets?

• When is a Use Case layer needed?

  - by Meta-Knight

  In his blog post The Clean Architecture Uncle Bob suggests a 4-layer architecture. I understand the separation between business rules, interfaces and infrastructure, but I wonder if/when it's necessary to have separate layers for domain objects and use cases. What added value will it bring, compared to just having the uses cases as "domain services" in the domain layer? The only useful info I've found on the web about a use case layer is an article by Martin Fowler, who seems to contradict Uncle Bob about its necessity: At some point I may run into the problems, and then I'll make a Use Case Controller - but only then. And even when I do that I rarely consider the Use Case Controllers to occupy a separate layer in the system architecture. Edit: I stumbled upon a video of Uncle Bob's Architecture: The Lost Years keynote, in which he explains this architecture in depth. Very informative.

• Turn off laptop display and have monitor

  - by Ryan B

  My laptop display has stopped working and is unfixable! Anyway, I got a full HD monitor and plugged that into the HDMI port of the laptop. I have changed the power settings so that I can close the lid and still have the monitor on, and this all works. However because it is on "mirror displays", I cannot get the full 1080p resolution that the monitor supports, and when I turn off mirror displays and switch off the laptop screen, the monitor will also switch off! I'm really stuck, as I can only get the monitor to display its full resolution if I have it with the laptop screen turned on, and I dont want this because (as the laptop display does not work) things get lost on that side of the screen. HELP. (Dell Studio 1537 Monitor is Samsung SA300 Connected through HDMI Ubuntu 11.10)

• Adding an LOV to a query parameter (executeWithParams)

  - by shay.shmeltzer

  I showed in the past how you can use the executeWithParams operation to build your own query page to filter a view object to show specific rows. I also showed how you can make the parameter fields display as drop down lists of values (selectOneChoice). However this week someone asked me if you can have those parameter fields use the advanced LOV component. Well if you just try and drag the parameter over, you'll see that the LOV option is not there as a drop option. But with a little bit of hacking around you can achieve this. (without actual Java coding). Here is a quick demo:

• What is more preferable, Creating dedicated domains for mobile apps that shares different content or associate them with folders in one domain?

  - by Abdullah Al-Khalidi

  I want to consult you in an SEO matter which i am completely lost with, I've built a social mobile application that allows users to share text content and made all the content that appears on the application available via the web through dedicated links, however, those links cannot be navigated through the website but they are generated when users shares content through the app to social media networks. I've implemented this method on three applications with totally different content, and I've directed all generated URLs to be from the main company website which is http://frootapps.com so when users shares something, the url will change to http://frootapps.com/qareeb/share.aspx?data=127311. My question, which one is more preferable, a dedicated website for each app that uses such method? or it is ok to keep doing it the same way I am doing it?

• How do you update copyright notices?

  - by James

  So now it's 2011, and as I carry on coding on our active projects it's time to update some copyright notices. eg. Copyright Widgets Ltd 2010 to Copyright Widgets Ltd 2010, 2011 My question is when do you update the copyright notices? Do you change the notice in the head of a file the first time you work on that file? Since a module is one piece of code consisting of many files that work together, do you update all notices in that module when you change a single file in that module? Since a program is one piece of code (maybe consisting of many modules), do you update all notices in that program when you change a single file in that program? Or do you just go through and change en-mass over your morning coffee on the grounds your about to start programming and updateing things?

• Is there value in having technical authors in a software team?

  - by Desolate Planet

  During my 5 years in IT as a software developer, I've noticed that developers have a strong distaste towards doing any documentation. The act of taking screenshots and creating documentation seems to be a painful and time consuming experience. In one company I worked for, we had a technical documentation team with two technical authors and they developed all the user guides for our customers. In other companies where I've suggested hiring a technical author, I've been told they are not worth the money, but I'm a little unsure if that rings true. Is it better to have developers stop coding and take half a day to do screenshots and create the various guides or is it worth hiring someone who handles such tasks?

• Why did Ubuntu and Windows start hanging mysteriously after I took a vacation?

  - by Ashrey Goel

  I installed Ubuntu alongside my Windows 7, after partitioning my HDD using Easeus partitioning manager. It was working perfectly, no problems, no data lost or corruption. Then I went away for 2 days and in my absence I don't know what happened in that period, now both Windows 7 and Ubuntu keep hanging continuously, like when you paint and change a brush it'll hang, I mean on very simple commands and I know my computer does not hang on such petty things. I use it for developing music and the specification are: Model: DELL-XPS Processor: Intel i5, 2.53 GHz RAM/Memory: 4GB Hard disk size: 500GB HDD Windows 7 partition: 417 GB Ubuntu Partition: 50 GB Please Help.

• How is architectural design done in an agile environment?

  - by B?????

  I have read Principles for the Agile Architect, where they defined next principles : Principle #1 The teams that code the system design the system. Principle #2 Build the simplest architecture that can possibly work. Principle #3 When in doubt, code it out. Principle #4 They build it, they test it. Principle #5 The bigger the system, the longer the runway. Principle #6 System architecture is a role collaboration. Principle #7 There is no monopoly on innovation. The paper says that most of the architecture design is done during the coding phase, and only system design before that. That is fine. So, how is the system design done? Using UML? Or a document that defines interfaces and major blocks? Maybe something else?

• How can I create and animate 2D skeletons for HTML5 Javascript games? [on hold]

  - by user414209

  I'm trying to make a 2D fighting game in HTML5(somewhat like street fighter). So basically there are two players, one AI and one Human. The players need to have animations for the body movements. Also, there needs to be some collision detection system. I'm using createjs for coding but to design models/objects/animations, I need some other software. So I'm looking for a software that can: easily make custom animation of 2d objects. The objects structure(skeleton etc.) will be same once defined but need to be defined once. Can export the animations and models in a js readable format(preferably json) Collision detection can be done easily after the exported format is loaded in a game engine. For point 1, I'm looking for some generic skeleton based animation. Sprite-sheet based animations will be difficult for collision detection.

• Game-a-Week One Completed

  - by Matt Christian

  Last night I finished my Game-a-Week One and felt and extreme sense of accomplishment with what I finished in a single week. I removed all traces of the JigLibX code since it wasn't working properly due to my implementation and got my collision working thanks to some BoundingSpheres and Riemer's tutorials.  However, since the characters are Corndogs a rectangle bounding box would have made more sense although the bullets are only able to move forward currently. While developing it in a week was a challenge, developing it in a week while maintaining proper coding standards and clean, reusable code was damn near impossible.  It's possible my next step will be to either refactor it or move onto Game-a-Week Two. I will post a link to the game ZIP in the future.

• Where to find a mentor?

  - by Fanatic23

  I have been looking around for resources that discuss about mentors, including questions in the stackexchange network. I see that the general response has been to join open source projects and/or check out local user groups if there exists any. Are we sure that joining open source project can get me a mentor? It can grab eyeballs, yes, if the project is exciting enough but a mentor? I am not so sure. What do you guys think? Finally, I'd want my mentor to be in a specific domain as opposed to just being a coding wizard and that makes the search even more difficult. Suggestions?

• Is the abundance of Frameworks dumbing down programmers?

  - by Gratzy

  With all of the frameworks available these days ORM's DI/IoC etc. I find that many programmers are losing or don't have the problem solving skills needed to solve difficult issues. I've seen many times unexpected behaviour creep into applications and the developers unable to really dig in and find the issues. It seems to me that deep understanding of whats going on under the hood is being lost. Don't get me wrong, I'm not suggesting these frameworks aren't good and haven't moved the industry forward, only asking if as a unintended consequence developers aren't gaining the knowledge and skill needed for deep understanding of systems.

• Is reference to bug/issue in commit message considered good practice?

  - by Christian P

  I'm working on a project where we have the source control set up to automatically write notes in the bug tracker. We simply write the bug issue ID in the commit message and the commit message is added as a note to the bug tracker. I can see only a few downsides for this practice. If sometime in the future the source code gets separated from the bug tracking software (or the reported bugs/issues are somehow lost). Or when someone is looking in the history of commits but doesn't have access to our bug tracker. My question is if having a bug/issue reference in the commit message is considered good practice? Are there some other downsides?

• How can a student programmer improve his teamwork skill?

  - by xiao

  I am a student right now. Recently, I am working in a project as a leader with three other students. Due to the lack of experience, our project is progressing slowly and our members are frustrated. They do not feel sense of accomplishment in the project. I am pressured and frustrated, too. But as a team leader, I think I need to push them. But I do not know how to do. Do I help them solve coding problem or just encouragement? But if I pay too much attention on it, it would slow down my own progress. It is a not technical question, but it is very common in software development. I hope veteran programmers would give me some suggestions. Thanks!

• How to coach a developer with dyslexia to improve his spelling and grammar capabilities?

  - by Uwe Keim

  Just having read this question regarding developers with dyslexia, I still have some open questions on how to deal with it: I am working on a project sinc approx. 6 month with a new developer who just finished university. I see that the code quality is high, what he's missing is the ability to write texts (even short ones) in an error-free manner (both, syntax and grammar errors). He is working on some UI stuff (VS.NET 2010, ASP.NET 4) and, beside coding, has to write short text for labels, buttons, grid view headers, page titles, etc. Since even those texts have errors inside, no matter how much I try to discuss the need for a professional, text-error-free UI, he seems to not manage to get this right, although he really tries. So my questions are: Are there any hints how he (or I) should proceed to enhance the text quality? Do you know any tools (like inline spell checkers) for VS.NET to highlight syntax and grammar errors? (We are working on a German-only UI, if this is important to know)
