  • Linux Lightweight Distro and X Windows for Development

    - by Fernando Barrocal
    Heyall... I want to build a lightweight linux configuration to use for development. The first idea is to use it inside a Virtual Machine under Windows, or old Laptops with 1Gb RAM top. Maybe even a distributable environment for developers. So the whole idea is to use a LAMP server, Java Application Server (Tomcat or Jetty) and X Windows (any Window manager, from FVWM to Enlightment), Eclipse, maybe jEdit and of course Firefox. Edit: I am changing this post to compile a possible list of distros and window managers that can be used to configure a real lightweight development environment. I am using as base personal experiences on this matter. Info about the distros can be easily found in their sites. So please, focus on personal use of those systems Distros Ubuntu / Xubuntu Pros: Personal Experience in old systems or low RAM environment - @Schroeder, @SCdF Several sugestions based on personal knowledge - @Kyle, @Peter Hoffmann Gentoo Pros: Not targeted to Desktop Users - @paan Don't come with a huge ammount of applications - @paan Slackware Pros: Suggested as best performance in a wise install/configuration - @Ryan Damn Small Linux Pros: Main focus is the lightweight factor - 50MB LiveCD - @Ryan Debian Pros: Very versatile, can be configured for both heavy and lightweight computers - @Ryan APT as package manager - @Kyle Based on compatibility and usability - @Kyle -- Fell Free to add Prós and Cons on this, so we can compile a good Reference. -- X Windows suggestion keep coming about XFCE. If others are to add here, open a session for it Like the distro one :)

  • TextMate tips for Rails Development

    - by Ganesh Shankar
    Working on Rails code for a bit has started me on the spiral into obsessively customising my dev environment (I say obsessive as at the last Rails meetup I went to there was some guy who was raving about shaving milliseconds off each line of code and therefore upto half an hour a day... I hope I don't become that guy...) I spend most of my time in TextMate so it seemed like a great place to start the optimising... So far I've added a few TextMate bundles like Git Bundle, Project Plus and the theme from Railscasts. I've noticed some of the other TextMate users I've come into contact with using heaps of nifty keyboard shortcuts and other plugins to help make their dev environment more friendly. Looking around the net, I was a bit overwhelmed by the amount of shortcuts and plugins available... So I was hoping to hear from other Rails developers out there: What are some good keyboard shortcuts and plugins that I should be aware of for TextMate with specific reference to Rails Development? I've read this question on SO: http://stackoverflow.com/questions/99807/what-are-some-useful-textmate-shortcuts but I was wondering if there was something a bit more specific to Rails development.

  • How do you apply a Theme to a Silverlight 3 application?

    - by skb
    I am trying to build a Silverlight website, using standard Silverlight controls. I read that Silverlight 3 comes with 9 proffessionally design Themes. I really want to use them, but everywhere I look just talks about making you own theme, or other tangential topics. Can anyone tell me how to apply one of the out-of-the-box themes? Or, if there is any tribal knowledge that those themes suck, where some other standard themes can be found?

  • Should Development / Testing / QA / Staging environments be similar?

    - by Walter White
    Hi all, After much time and effort, we're finally using maven to manage our application lifecycle for development. We still unfortunately use ANT to build an EAR before deploying to Test / QA / Staging. My question is, while we made that leap forward, developers are still free to do as they please for testing their code. One issue that we have is half our team is using Tomcat to test on and the other half is using Jetty. I prefer Jetty slightly over Tomcat, but regardless we using WAS for all the other environments. My question is, should we develop on the same application server we're deploying to? We've had numerous bugs come up from these differences in environments. Tomcat, Jetty, and WAS are different under the hood. My opinion is that we all should develop on what we're deploying to production with so we don't have the problem of well, it worked fine on my machine. While I prefer Jetty, I just assume we all work on the same environment even if it means deploying to WAS which is slow and cumbersome. What are your team dynamics like? Our lead developers stepped down from the team and development has been a free for all since then. Walter

  • New to web development - backend questions

    - by James
    I'm new to web development although I'm confident in the roadmap for the front-end. I need direction on two things: Basic architecture Back-end technologies For architecture, what do I need to get started? From what I know, its: Get a domain name registered (godaddy?) Find a web host ??? anything else? or start developing the site? I don't think its that easy, there must be something I'm missing, right? For the back-end technologies, I have application development experience with Java and Python, but how likely is it to find a back-end hosting site that supports these languages over PHP? Is PHP a better choice? If I stick with what I know for the back-end, am I sabotaging myself later on? If I need help, how is the market for a python/java developer vs. a php developer? What do I need to know about databases? I have some basic SQL experience. Do hosting sites have limitations on the type of databases or bandwidth I need to worry about? I'm working through some of the common sites: StackOverflow, Sitepoint forums, Google, etc...are there other resources I should use?

  • Silverlight Vs. WPF Vs. Winforms What is good for specifically my purpose?

    - by Cyril Gupta
    I am about to start a new Windows applications and the contenders for the platform are: Windows Forms WPF Silverlight Now my experience with WPF at least in my last application was not very encouraging (the app failed to run on the deployment machines and I had to re-do it in Winforms). So my confidence is shaken here. My app is for mass-distribution (the last version had some 100,000+ installations). So I want to make absolutely sure that my users will be able to use it and enjoy it without any problems. I would love to create a nice interface, going the next step like a Flex or Silverlight, iPhone app, with animations and effects. So I would really like to go with WPF or Silverlight if I can. My needs are Good support for visuals and animation effects. Support for database connectivity. Support for printing (Is there an equivalent of PrintDocument in Silverlight) Must not suffer from deployment troubles. Silverlight is universal, but does it have printing support and good controls toolset? WPF has printing support and a nice toolset, but can I depend on it? Winforms is dated already and is not so impressive, but should I go with it anyway? Your advice would be appreciated

  • IronPython 2.6.1 for .NET 4.0 RC targeting Silverlight?

    - by Fastidious
    Since the 2.6.1 .NET 4.0 RC release of IronPython (found @ http://ironpython.codeplex.com/releases/view/40146) does not include Silverlight binaries I am wondering if anyone has had any success getting it working themselves. I'd assume it would not be too hard to recompile the source against Silverlight but I can't seem to locate it on Codeplex. EDIT: Per the IronPython team, Silverlight 4 is not yet a stable release so no fully compatible binaries have been released.

  • Cobol web development/hosting resources

    - by felixm
    Hello, I'm employed at a fairly big company here in Germany and got the job to create the main website for it which will feature: Static contents; Information and Presentations An employee area (around 6000 employees) featuring various things from calenders, job descriptions, some sort of groups Too many other dynamic things I can't list here I have decided to use COBOL for the job, it may be very underrated but it is a very powerful language, especially for business apps and, as my co-workers say, web (2.0) development too. I also need to use COBOL because all the backend and transactions system of the company is programmed in it (some small parts were programmed in LISP too, idk exactly why). I also have received an API that makes it possible to use COBOL with MySQL easily. This is a big project and it will probably take more than 2 months programming it. What do I have to expect when building a huge web app in COBOL? Are there web frameworks for COBOL available? Some sort of MVC? Are there any good resources for practical web-development with COBOL? Thanks in advance

  • Should I use MEF or Prism for my Silverlight project?

    - by Daniel
    Hi! My team(3 developers) will be building a Silverlight LOB application. This is the first Silverlight project for us. We've been doing mostly Winforms. We'll be using Silverlight4 / VS2010 / possibly WCF RIA Services, and ASP.NET Web application to handle authentication and host the silverlight pages. We need a way to.. Modularize the silverlight project so we can work in different parts of the application, then integrate them. Dynamically load different parts of the application, so the initial download size of the xap file wouldn't be too large. After some research, I found out that Prism and MEF are possible solutions to these goals. Can you give me advice on which framework to use? or possibly another solution? We don't have much experience on Silverlight and the project needs to be finished in 3 months, so the learning curves for frameworks should be considered. Thank you for reading! Any inputs will be much appreciated.

  • Binding ComboBoxes to enums... in Silverlight!

    - by Domenic
    So, the web, and StackOverflow, have plenty of nice answers for how to bind a combobox to an enum property in WPF. But Silverlight is missing all of the features that make this possible :(. For example: You can't use a generic EnumDisplayer-style IValueConverter that accepts a type parameter, since Silverlight doesn't support x:Type. You can't use ObjectDataProvider, like in this approach, since it doesn't exist in Silverlight. You can't use a custom markup extension like in the comments on the link from #2, since markup extensions don't exist in Silverlight. You can't do a version of #1 using generics instead of Type properties of the object, since generics aren't supported in XAML (and the hacks to make them work all depend on markup extensions, not supported in Silverlight). Massive fail! As I see it, the only way to make this work is to either Cheat and bind to a string property in my ViewModel, whose setter/getter does the conversion, loading values into the ComboBox using code-behind in the View. Make a custom IValueConverter for every enum I want to bind to. Are there any alternatives that are more generic, i.e. don't involve writing the same code over and over for every enum I want? I suppose I could do solution #2 using a generic class accepting the enum as a type parameter, and then create new classes for every enum I want that are simply class MyEnumConverter : GenericEnumConverter<MyEnum> {} What are your thoughts, guys?

  • Reorganizing development environment for single developer/small shop

    - by Matthew
    I have been developing for my company for approximately three years. We serve up a web portal using Microsoft .NET and MS SQL Server on DotNetNuke. I am going to leave my job full time at the end of April. I am leaving on good terms, and I really care about this company and the state of the web project. Because I haven't worked in a team environment in a long time, I have probably lost touch with what 'real' setups look like. When I leave, I predict the company will either find another developer to take over, or at least have developers work on a contractual basis. Because I have not worked with other developers, I am very concerned with leaving the company (and the developer they hire) with a jumbled mess. I'd like to believe I am a good developer and everything makes sense, but I have no way to tell. My question, is how do I set up the development environment, so the company and the next developer will have little trouble getting started? What would you as a developer like in place before working on a project you've never worked on? Here's some relevant information: There is a development server onsite and a production server offsite in a data center . There is a server where backups and source code (Sourcegear Vault) are stored. There is no formal documentation but there are comments in the code. The company budget is tight so free suggestions will help the best. I will be around after the end of April on a consulting basis so I can ask simple questions but I will not be available full time to train someone

  • Am I fundamentally misunderstanding how Silverlight runs? (debugging issues)

    - by SP
    I've got a vs2010 solution containing an ASP.Net 4 website, and a Silverlight 4 project. The website is linked to the Silverlight project ('Map') and the ClientBin folder contains a Map.xap file. The Map project is very simple. It contains the default App.xaml and App.xaml.cs files. The MainPage.xaml file looks like this <UserControl x:Class="Map.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="380" d:DesignWidth="800"> <Canvas x:Name="MainCanvas" Width="800" Height="380"> <Canvas.Background> <ImageBrush ImageSource="map.png" Stretch="None"/> </Canvas.Background> </Canvas> The code behind for that looks like this: public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); throw new Exception(); } } Inside one of the website pages I have the default object pointing to my Silverlight xap When I run the website, I see my background image on the Canvas in the Silverlight window, so I know it's working in that sense. However, I cannot break on any breakpoints set in the MainPage.xaml.cs file (in IE). I have checked the correct settings for Silverlight debugging. And see that Exception I'm throwing in the MainPage constructor? I'm not seeing that either. In fact, nothing I put in there seems to be run at all, but I know the xaml is rendering because I can see my canvas background. What am I not getting here?

  • How to disable silverlight (when creating sites) in SharePoint 2010?

    - by Jay

  • Silverlight and MV(VM) Pattern - No Code-Behind - Is this possible?

    - by user118190
    I am working on Silverlight 3.0 and currently using code-behind in my Views. I would like to implement the MV(VM) pattern into my project as the project is growing. I have seen some WPF projects where the code-behind has NO CODE except for the InitializeComponent method, which I believe is the right way to go and just looks clean. Is this possible in Silverlight 3.0, that is, no code-behind? Can anyone point me to some good Silverlight (3.0) MV(VM) tutorials / articles?

  • Does Silverlight require the .NET framework to be installed?

    - by Mohit Deshpande
    I have been exploring the possibilities of Microsoft Silverlight and how it runs in web browsers. I just wonder if Silverlight requires the .NET framework? Meaning that Mac or Linux users cannot run Silverlight. I will be making the application using the .NET framework 3.5. Will this application run in any web browser, or just major ones like Internet Explorer, Firefox, or Safari?

  • Setting the size of a silverlight window at runtime automatically?

    - by dilbert789
    I need to be able to change the size of my Silverlight object at run time because I have content that changes in size dramatically between pages, and I'd rather not show a Silverlight scroll bar inside the browser scroll bar. I was able to do the following to get it to work: In the aspx page hosting the silverlight control: - Set your Div to the starting size you need it to be - Set the Silverlight Obejct to width=”100%” height=”100%” In your Main page add this: public static void ChangeSize(string height) { var myDiv = HtmlPage.Plugin.Parent; while (myDiv.TagName != "div") myDiv = myDiv.Parent; myDiv.SetStyleAttribute("height", height); } Anywhere you want to now change the size of the page do this: string newHeight = (App.Current.Host.Content.ActualHeight + 75).ToString(); MainPage.ChangeSize(newHeight + "px"); //App.Current.Host.Content.ActualHeight will get the current actual height of the object Is there a way that I can set this to re-size automatically so that I do not have to specify the amount to change? Currently using SL 2, interested in if there is another way in a different version though.

  • Win a Free License for Windows 7 Ultimate or Silverlight Spy at Our West Palm Beach .Net User Group

    - by Sam Abraham
    Shervin Shakibi, Microsoft Regional Director, ASP.Net MVP and Microsoft Certified Trainer will be our speaker at our West Palm Beach .Net User Group May meeting,  Shervin founded the FlaDotNet Users Group Network to which our West Palm Beach .Net User Group belongs. Shervin will be talking to us about the new features of Silverlight 4.0. I am personally looking forward to attending this event as I have always found Shervin's talks fun and a great learning experience.   At the end of our meeting, we will be having a free raffle. We will be giving away 1 free Windows 7 Ultimate license and 2 free Silverlight Spy licenses as well as several books and other giveaways. Usually, everybody goes home with a freebie.  We will also continue having ample networking time while enjoying free pizza/soda sponsored by Sherlock Technology and SISCO Corporation who is a new sponsor of our group.   Koen Zwikstra, Silverlight MVP and Founder of First Floor Software has kindly offered the West Palm Beach .Net User Group several free licenses of Silverlight Spy to raffle during our meetings. We will start by raffling two copies during our May meeting.   Silverlight Spy is a very valuable tool in debugging Silverlight applications. It has been mentioned at MIX10 ( http://firstfloorsoftware.com/blog/silverlight-spy-at-mix10/) as well as by Microsoft Community Leaders (http://blogs.msdn.com/chkoenig/archive/2008/08/29/silverlight-spy.aspx)   I am using Silverlight Spy myself and will probably be using it to demonstrate Silverlight internals during my talks. I think Koen's gift to our group will bring great value to our fortunate members who end up winning the licenses. Thank you Koen for your kind gift and looking forward to meeting you all on May 25th 2010 6:30 PM at CompTec (http://www.fladotnet.com/Reg.aspx?EventID=462)   Sam Abraham Site Director - West Palm Beach .Net User Group

  • Beginning Game Development on iPhone/iPad [closed]

    - by Ilya Knaup
    I'm willing to begin learning iPhone Game development. The problem is that I've found many resources for older models of iPad and iPhone. As you know now both have retina displays and amazingly fast graphics processors (Older resources don't take advantage of it). So I'm here to ask you for help on how to kickoff the development. Any recent tools, libraries, standards etc. Is there anything you can recommend? Ideally game should work on both iPad and iPhone, Retina and non Retina. It's going be a 2d / cartoon graphics based game with intense touching (So detecting touches quiet fast is a must have). Any advice, everything you that could help us started is very much appreciated.
