  • Thoughts of Cloud Development/Google App Engine

    - by jiewmeng
    I use mainly PHP for web development, but recently, I started thinking about using Google App Engine. It doesn't use PHP which I am already familiar with, so there will be a steeper learning curve. Probably using Python/Django. But I think it maybe worthwhile. Some advantages I see: Focus on App/Development. No need to setup/maintain server ... no more server configs Scales automatically Pay for what you use. Free for low usage Reliable, it's Google after all Some concerns though: Does database with no joins pose a problem for those who used App Engine before? Do I have to upload to Google just to test? Will it be slow compared to testing locally? What are your thoughts and opinions? Why would you use or not use App Engine?

  • Switching CSS to use asset pipeline in Rails?

    - by John
    I have a lot of legacy CSS files from what was a Rails 2.x app that got upgraded to Rails 3.2.8, and I want to switch over to using the Rails asset pipeline for stylesheets. The issue is, the CSS stuff is messy in terms of huge lines of code, duplicate file names, and unorganized folder structure. After looking through individual pages, and trying to add individual stylesheets and folders into the asset pipeline and spending some cycles debugging, I realized there's probably a better approach. Is there a way to test to make sure the old CSS matches up with the asset pipeline CSS? What are some good tools for testing and debugging CSS?

  • Accidentally uninstalled Ubuntu 14.04 system settings. How to get them back?

    - by Dan
    Somehow, cleaning up useless software (using software center), I uninstalled Ubuntu "system settings". I did this by mistake. Now I fail to find system settings application using software center (and there are so many items in history...). It seems strange to me because usually when I try to uninstall something critical (system testing for example), the dependencies manager tells me It will uninstall the whole desktop system then. I am sure I did not have that warning. So I need the name of the software to install or a command line command rather than a system restore to get it back. Very interesting thing. If you ever want to play with this and reproduce it, you will be confused to see Ubuntu Mobile system settings instead! Yes, mobile network and touchscreen settings! Happy pre-release viewing!

  • Using GridView and DetailsView in ASP.NET MVC - Part 1

    - by bipinjoshi
    For any beginner in ASP.NET MVC the first disappointment is possibly the lack of any server controls. ASP.NET MVC divides the entire processing logic into three distinct parts namely model, view and controller. In the process views (that represent UI under MVC architecture) need to sacrifice three important features of web forms viz. Postbacks, ViewState and rich event model. Though server controls are not a recommended choice under ASP.NET MVC there are situations where you may need to use server controls. In this two part article I am going to explain, as an example, how GridView and DetailsView can be used in ASP.NET MVC without breaking the MVC pattern.http://www.bipinjoshi.net/articles/59b91531-3fb2-4504-84a4-9f52e2d65c20.aspx

  • Font rendering in Firefox is blurry

    - by Mehrdad
    A picture is worth a thousand words... so does anyone know how to fix this font blurriness in Firefox? (You'll need to right-click the picture below go to View Image to view it full-size; it's too small to see anything here.) Note: My other applications (and the Firefox non-client area, as you can see in the screen) are completely fine, so obviously going to System-Appearance and changing the font settings isn't fixing the situation. Edit: Not letting web pages to use their own fonts also doesn't help: See how the upper one is still sharper? Also, Firefox's own menu bar doesn't render the same way as the page content (menu bar below, page content above). They're both Segoe UI:

  • In the Mobile and Tablet World, How Much is Too Much?

    - by andrewbrust
    The week of April 26th was a huge one in the world of mobile and tablet devices,  There were so many individual developments, announcements and solidifications of strategy, it’s almost impossible to believe they occurred in the same month, let alone the same week. Things started with Apple and Gizmodo having a Law and Order moment over the latter’s procurement of what appears to be the former’s 4th gen iPhone prototype.  We found out on the 26th that Gizmodo blogger Jason Chen’s apartment was raided by police and, honestly, that was a bit much. But Apple didn’t stop there.  They also published Steve Job’s critique of Adobe Flash and his explanation of Cupertino’s embargo of Flash on iPhones, iPods and iPads.  If you ask me, this too, was a bit much. Apple finished up the week by releasing the 3G version of its iPad product to the US market. I like (iLike?) my WiFi iPad.  The idea of getting a version of it that required a second 3G service monthly subscription, is, well, a bit  much. Microsoft was in the news too.  It killed a project it hadn’t even acknowledged the existence of: the Courier tablet.  That’s a bit much too.  If a tree falls in the woods, and Microsoft says they can’t hear it anyway, could they really have chopped it down? Maybe Microsoft Research should have licensed some of Courier’s technology from other parts of Microsoft.  Then maybe they could have kept the product alive.  Ask HTC: they’re going to be licensing technology from Microsoft because Redmond insists that Google’s Android operating system infringes on certain of their patents.  And since HTC now builds a number of handsets on Android, instead of being beholden, as they once were, to Windows Mobile, that means they can keep making their products.  Why does HTC have to pay the royalties, and not Google?  Maybe Microsoft decided that going after GOOG would have been a bit much, even for them. The agreement came not a moment to soon: HTC released their “Droid Incredible” (that name’s a bit much), an Android 2.1 handset with amazing hardware and HTC’s own Sense UI, on April 30th (this past Friday). This phone is very well-reviewed.  Maybe that’s why Google basically decided to beg off introducing a version of its Nexus One phone (also manufactured by HTC) on the Verizon Wireless network.  Google backing down?  That’s incredible, if not also a bit much. And that brings us to HP.  Which this week announced its acquisition of Palm and its webOS mobile phone touch-oriented operating system.  HP also killed its own Slate initiative.  Apparently HP realized that Windows 7, even with a proprietary HP touch UI added on top, is no match for the iPad.  I’m guessing they think webOS might work a bit better,  And I’m wondering if HP even wants to use webOS for phone handsets, beyond the Pre and Pixi.  Using it just for slate devices would be a bit extreme, but maybe not too much. Honestly, this was not Microsoft’s best week.  It killed a project and a close partner did likewise.  Then that same partner bought a competing OS product, while another partner released their new product that uses yet another competing OS platform. What did Microsoft actually produce this past week? An update to its Windows Phone 7 developer tools that actually works with the version of Visual Studio 2010 released on April 12th, and the version of Silverlight released three days later. That took three weeks to get synced up, and that’s a bit much too. But at least it happened. Windows Phone 7 is Microsoft’s best hope for a comeback in the SmartPhone market and to offer a credible touch-based tablet device.  This week, two of Microsoft’s slate initiatives died, and its only mobile phone victory was around its competitor’s operating system.  I hope the new platform gets Redmond out of the PC ghetto and into the classes of device that get people really excited today.  If it can’t, that would be a bit much; probably too much.  And, as the signs at the Lonestar Cafe in NYC used to say, too much ain’t enough.

  • Windows Phone 8 development on Windows 7 - is it or will be possible?

    - by Tiby
    I was trying to install Windows Phone 8 SDK on my Windows 7 machine and it hit me with the 'supported only on Windows 8' message. I actually wanted to develop Phone 7.5 apps on Visual Studio 2012, impossible thing with the 7.1 SDK, so I thought 8 SDK will do the job. As if it was not enough that the 8 SDK was controversial upon release, now that it's generally available, to me it seems like a horrible decision to make it available only for Windows 8, because in my humble opinion, no serious and sane developer will install Windows 8 ever, or at least in the near future, just because of the Metro UI. So, anyone knows any workarounds for developing Windows Phone 8 on Windows 7, or at least develop for 7.5 but using Visual Studio 2012?

  • Dude, where is my list instance?

    - by MOSSLover
    I saw an MSDN Forum post today, so I looked for a ListInstance Hidden property in SharePoint 2007 features.  There is none, but interestingly enough there is one in 2010.  I wondered what would happen if you did this: <Elements xmlns="http://schemas.microsoft.com/sharepoint/">   <ListInstance            FeatureId="00bfea71-de22-43b2-a848-c05709900100"            Title="Hidden List Test"            Description="Testing a hidden list."            TemplateType="100"            Hidden="TRUE"            OnQuickLaunch="FALSE"            Url="Lists/TestHidden" /> </Elements> It hides the entire list from SharePoint Designer and the browser, however you can hit the list by typing in the url in internet explorer.  Pretty cool stuff.  Enjoy guys.

  • Xubuntu: Disks utility (palimpsest) and Gparted not showing up anywhere after installation

    So I've downloaded Gparted and Disks from the software center. According to software center, they've both installed successfully... but they're nowhere to be found. Even in my terminal: $ palimpsest palimpsest: command not found I've looked in usr/bin... no "palimpsest", no "gnome-disk-utility". In usr/share/gnome-disk-utility there's a bunch of .ui files. According to Software Center, both programs are now installed in my computer, but it seems I've no way to find them. I've tried re-installing and restarting. I'm on Xubuntu 32 bit.

  • Submitting Java Code with Junit unit test

    - by LivingThing
    I have mostly work on simple java programs and compiled and run it with eclipse on Windows. So, i have no experience of using command prompt for compiling Java projects and do not have much info about what actually happens beneath the play button in Eclipse. Now i have to submit a Java application which will have basic operation on XML. My project also will have (JUnit) Unit Test. My question is related to submission of this Project. Which files would be necessary to submit the code. So, it executes properly? Does chosing eclipse as an IDE or junit as a unit testing framweork produces any dependenices i.e the executor of the program should have eclipse/libraries to execute the program on his machine?

  • New JDeveloper/ADF book hits the bookshelves

    - by Grant Ronald
    I've just received a nice new copy of Sten Vesterli's book Oracle ADF Enterprise Application Development - Made Simple.  I was one of the technical reviewers of the book but I'm looking forward to be able to read it end-to-end in good old fashioned book format this coming week. The book bridges the gap between those existing books that describe Oracle ADF features, and real world ADF development.  So, source control, bug tracking, estimating, testing, security, packaging etc are all covered.  Of course, every project and situation is different so the book could never supply a one-size-fits-all guide, but I think its a good addition to your ADF bookshelf.  I'll hopefully post a full review in the coming weeks. Oh, and congratulations Sten,  having gone through the pain of writing my own ADF book, I take my hat off to anyone who goes through the same journey!

  • 13.04 Gnome - removing icons from lower panel

    - by Mikey
    I use the stripped down Gnome UI for 13.04 (Gnome-no effects) and on the bottom there is a panel where you can put icons for app launchers, by dragging them from applications menu. This is probably a really dumb question, but I can't figure out how to REMOVE a launcher icon from that panel once I put there! How is this done? Note - I saw another answer that said click alt-super and right click on top panel - I clicked remove launcher and now my top Application and Places menus are gone! How do I get them back - all screwed up now.

  • Should the Joel Test be essential for every software company? [closed]

    - by Mahbubur R Aaman
    Joel Test has 12 steps for better code. They are: Do you use source control? Can you make a build in one step? Do you make daily builds? Do you have a bug database? Do you fix bugs before writing new code? Do you have an up-to-date schedule? Do you have a spec? Do programmers have quiet working conditions? Do you use the best tools money can buy? Do you have testers? Do new candidates write code during their interview? Do you do hallway usability testing? Should these steps mandatory for every software companies? While recruiting programmers, then programmers should ask the company, as they follow joel steps?

  • How do people deal with Android fragmentation?

    - by Bill
    I've spent the past few years working on iOS apps, and I'm now giving some serious consideration to creating an Android port of one of my apps. I'm sure that complaints about fragmentation are a frustrating cliche to experienced Android programmers, but as an iOS programmer, I'm quite honestly overwhelmed by the number of configurations and devices that my app might end up running on. There are literally thousands of Android devices in the wild, but I know there are successful Android developers in the world and I know they're not testing or developing for thousands of different devices. So how can a relatively small company deal with fragmentation? Is it possible to pick the five or six most popular devices, focus on those and prevent the app from being installed on any other devices? Are there any other strategies for practically dealing with the number of different configurations an app will face?

  • Should I reuse variables?

    - by IAdapter
    Should I reuse variables? I know that many best practice say you should not do it, however later when different developer is debugging the code and have 3 variables that look a like and only difference is that they are created in different places in the code he might be confused. unit-testing is a great example of this. However I do know that best practice are most of the time against it. For example they say not to "overide" method parameters. Best practice are even are against nulling the previous variables (in Java there is Sonar that has warning when you assign null to variable that you don't need to do it to call garbage collector since Java6. you cant always control what warnings are turned off, most of the time the default is on)

  • Visual Studio 2012 - Setting the target framework in C++ Projects

    - by Igor Milovanovic
    The Visual Studio 2012 doesn’t have a UI to set the Target Framework in C++ Projects.     Target Framework : 4.0   The online documentation does say to edit the .vcxproj project and change the TargetFrameworkVersion Tag. However, The C++ projects don’t have that tag by default. They just assume that the target framework is v4.0.   Instead, you have to add the TargetFrameworkVersion-Tag to the PropertyGroup Globals.   1: <PropertyGroup Label="Globals"> 2: ... 3: <RootNamespace>...</RootNamespace> 4: <TargetFrameworkVersion>v4.5</TargetFrameworkVersion> 5: </PropertyGroup>   When you reload the project, the target framework version in your project will be changed.

Eclipse is okay but i cant fold if/while blocks and slow. Gedit can be extended and i have tried it but still i could not fold code or show error. I currently use Geany but it doesn't inform me of syntax errors as i type. If you have ways to solve the problems with above editors they too are also welcome
