  • On Teaching Open Source Development

    <b>IT World:</b> "One of the constants in my interactions with the Linux and open source communities is that they--all of them--are out there, in the big wide world, while I remain ensconced in my fortress of solitude here in Northern Indiana."

  • PHP/MySQL Database application development tool

    - by RCH
    I am an amateur PHP coder, and have built a couple of dozen projects from scratch (including fairly simple e-commerce systems with user authentication, PayPal integration etc - all coded by hand from a clean page. Have also done a price comparison engine that takes data from multiple sites etc.). But I am no expert with OO and other such advanced techniques - I just have a fairly decent grasp of the basics of data processing, logic, functions and trying to optimize code as much as possible. I just want to make this clear so you have some idea of where I'm coming from. I have a couple of fairly large new projects on my plate for corporate clients - both require bespoke database-driven applications with complex relationships, many tables and lots of different front-end functions to manipulate that data for the internal staff in these companies. I figured building these systems from scratch would probably be a huge waste of time. Instead, there must be tools out there that will allow me to construct MySQL databases and build the pages with things like pagination, action buttons, table construction etc. Some kind of database abstraction layer, or system generator, if you will. What tool do you recommend for such a purpose for someone at my level? Open source would be great, but I don't mind paying for something decent as well. Thanks for any advice.

  • VMPlayer 9, Xubuntu 12.10, Rails Development - Freezing frequently

    - by douglasisshiny
    I have a new Vizio Ultrabook that came with Windows 7. I develop Rails applications, and it's a pain to do that in windows, so I setup a Xubuntu VM with 1GB ram and 2 CPU cores. I basically keep the VM open all the time and have enough memory not to worry. Sometimes I pause the VM. For the first few days, everything was fine. The fourth day, Xubuntu froze up while running a test (with Guard and RSpec). I didn't think much of it and restarted the VM and went on my way. The freezes started becoming more frequent, though. I don't think they are only when I run a test, but often they are. It'll happen quickly, too. Startup VM, save file, test runs, it freezes, all within 5 minutes. Of note: the VM is using a shared folder from Windows (where the code is). This may be the problem. Any other people experience something like this?

  • Oracle Java Olympics Between Russia, Ukraine, Belarus, Ukraine and Kazakhstan

    - by Tori Wieldt
    Last month, 151 universities in 11 locations (Saint-Petersburg, Moscow, Donetsk, Tomsk, Odessa, Rostov-on-Don, Ekaterinburg, Khabarovsk, Almaty, Kiev, and Samara) competed in the second round of the Oracle Java Olympics. For two weeks in February, the best university students from Russia, Ukraine, Belarus, Ukraine and Kazakhstan were invited to compete with each other and prove just how good they are in Java programming.  A team of engineers from Oracle Development center in Saint-Petersburg prepared the set of problems to solve during the competition. To win, participants needed to show deep knowledge of Java technologies from Classloader and NIO to Reflection and JavaDB. Students in each location had a PC with Oracle JDK 1.7u2 and Netbeans 7.1.  As a testing system, the organizers used the open source software Ejudge (with several tweaks specifically for the competition).  Participants submitted their solutions to the remote server where they were tested by prepared test harnesses. All results were posted in real-time. "I followed the competition coming in from the many sites, and it was a really exciting experience, like a horse race or football game!" exclaimed Java Evangelist Alexander Belokrylov. Congratulations to everyone who competed! The Olympic finals will on April 4th.

  • Projects to learn web development

    - by David McDavidson
    I'm trying to get a job as a web developer, but the great majority of jobs offers requires previous experience and a portfolio to prove you've got the required skills. Unfortunately I don't have any real experience or anything to show. The best way to learn is to try and tackle real world problems, so I'd like to know what would be some nice projects to learn stuff and that will look good in a portfolio?

  • Which version of Ubuntu is recommended for app developers?

    - by Wes
    I've searched around Ask Ubuntu and the App Developer site, but I can't seem to find the answers to my questions. I'm wanting to get back into programming, and I'd eventually like get into app development for Ubuntu, but I'm not sure where to get started. Which version of Ubuntu is currently recommended for app development, especially for those wanting to publish their apps to the Software Centre? Should app developers use the current LTS release, or, can any of the new releases be used? Should developers use the 32-bit or 64-bit edition of Ubuntu, or does this not matter? What effect would the above choices have on the eventual publication of an app? I'm truly sorry if this has been covered elsewhere. Cheers Wes

  • Software/Hardware Development?

    - by SwarthyMantooth
    Sincere apologies if this is the wrong place to ask this. I am a computer engineering student and I'm currently on my first co-op of the required 5 I have to take, and I've noticed that all I'm really given is software engineering jobs. I love developing software, but I don't want to lose out on the hardware aspect of computers, as having a hybrid knowledge of the two is why I chose this major in the first place. So I guess my question is: Are there any software engineering jobs that still allow you to handle and interface with hardware on a very low level? Or am I to be forced to choose which focus I love more?

  • Is there a Visual Studio style tool/IDE?

    - by Tim
    I have been developing in the windows space with Visual Studio for a while now with work, but I have also been using Ubuntu for a while and am keen to get into some software development for linux. I should also note. I am not looking for .NET and I am aware of mono. I am also familiar with c++ development and some python, so the language isn't so much relevant as the "all in one" aspect. I was interested to know if there is a useful all in one code/debug/design(gui) IDE similar to something like Visual Studio but for linux?

  • New Development Snapshot

    I've integrated OpenJDK 6 b18. If you're building IKVM from source, you need to download openjdk6-b18-stripped.zip. Changes: Integrated OpenJDK 6 b18. Fixed IKVM.Reflection bug in version number handling (for version parts 32K). Added support for generic parameter custom attributes to IKVM.Reflection (this is missing from June 2006 ECMA CLI spec). Fixed IKVM.Reflection Type.FullName bug. Nested types can also have a namespace...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Help me get started in TDD for web development

    - by Snow_Mac
    I've done a tiny, tiny bit of TDD in building an app for a company that I interned with. We used lots of mocking and wrote lots of assert statements, after reading lots of blogs, I'm convinced that TDD is the way to go, but how do you go about TDD web applications? My main framework is Yii in PHP. My main questions are: What do you test? Models? Controllers? Views? How do you know if the output is correct? All my web apps interact with a DB, are there cavets to that and gotchas? Can I do testing in Netbeans? Can you test form elements or just strictly objects & methods?

  • How can I ensure our project gets developed successfully, without having any project management experience? [migrated]

    - by Raven13
    I'm a web developer who is part of a three-man team that has been tasked with a rather large and complex development project. Other than some direction and impetus from management, we're pretty much on our own to develop the new website. None of us have any project management experience nor do my two coworkers seem like they would be interested in taking on that role, so I feel like it's up to me to implement some kind of structure to the development process in order to avoid issues down the road. What can I do as a developer without project management experience to ensure that our project gets developed successfully and avoid the pitfalls of developing a project without a plan?

  • Is agile about development or management?

    - by ashy_32bit
    On a debate over what Scrum is all about, I found that perhaps I totally misunderstood the agile thing. It appears to me that Scrum (which is certainly considered an Agile process) is all about managing features and sprints and roles and stuff with nothing to do with TDD, pair programming, CI, refactoring and other developer centric techniques and practices that I though (until now) are the heart of agile. Now I am facing a difficulty ! 1) Is Scrum agnostic to whether developers do agile practices? 2) Can you implement Scrum in a team that does not utilize automated tests? does not perform refactoring or does not adhere to the agile programming practices?

  • Webinar on Cross Platform Development with MonoTouch for the iPhone and Mono for Android on Wednesday

    - by Wallym
    The iPhone and Android are dominant in the marketplace. The two platforms currently have 85% of the smartphone marketplace and are continuing to grow that marketshare. Developers are being tasked with targeting these two platforms. In this session, we’ll take a high level look at how we can use c# and .NET knowledge to share code between iOS and and Android. We’ll look at linked files, using the Xamarin Mobile API, the challenges of running across platforms and frameworks, as well as other features of Visual Studio, Monotouch, MonoDevelop, and Mono for Android that allows us to write as much code that can run on both platforms.Here is the registration link: https://www302.livemeeting.com/lrs/8001676474/Registration.aspx?pageName=2w197495hzh0t56g

  • Software development, basics of design, conventions and scalability

    - by goce ribeski
    I need to improve my programming skills in order to achieve better scalability for the software I'm working on. Purpose is to learn the rules of adding new modules and features, so when it comes to maintaining existing ones there is some concept. So, I'm looking for a good book, tutorial or websites where I can continue to read about this. Currently, what I know and what I do is: to design relational database(3NF), make separate class for each table put that in MVC implement modular programming ...write code and hope for the best... I presume that next things I need to learn more deeply are: programming codex(naming, commenting, conventions...), organize functions building interfaces organizing custom made libraries, organizing API that I'm using, documenting, team work... ... At last what my job is, it does't need to affect your answer, PHP CodeIgniter developer.

  • Graphic demonstrating emphasis of front end in web apps

    - by sohail
    I remember stumbling across an amusing graphic a year or so ago which demonstrated the tiers of web development. The back-end was shown as a tiny box, but the front end was shown as a huge box crammed with lots of front-end technologies like AJAX, DHTML. This is all a vague recollection. Does anyone know where on the Intraweb this graphic might be? It was probably on a programming cartoon site, but I only view XKCD on a regular basis, and I couldn't find it on there. Although tagged as fun, my request does have a productive edge to it - it would be quite useful in driving home to my colleagues how UI top-heavy web application development has become.
