• Dropbox indicator icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• Web Application Nat Traversal

  - by pbreault

  We are deploying web applications in java using tomcat on client machines across the country. Once they are installed, we want to allow a remote access to these web applications through a central server, but we do not want our clients to have to open ports on their routers. Is there a way to tunnel the http traffic in a way that the central server can access the web application that is behind the firewall ? The central server has a static ip address and we have full control over it. We don't need to access the filesystem, we only want to access the web application itself through a browser.

• Mount to /dev/sdb1 without password

  - by Jarmo

  I am unable to mount a USB drive (or SD card) to my system without root access. When I plug in a USB drive, it is visible in the left column of Nautilus, but when I click on it to open it, I receive the error message Unable to mount 2.1 GB Filesystem Error mounting: mount exited with exit code 1: helper failed with: mount: only root can mount /dev/sdb1 on /media/sdb1 I am able to mount the drive using sudo mount -w /dev/sdb1, but this causes problems for operations such as creating startup discs, which requires unmounting and remounting the drive. I suspect this problem may be caused by the fact that when I upgraded from 11.10 to 12.04, I had an SD card plugged in. This caused the system to stall during later startups, as it could not find this drive. I remedied this by editing a line of /etc/fstab to read /dev/sdb1 /media/sdb1 vfat noauto 0 0 However, I am dual booting Ubuntu with Windows XP, and I have no problem mounting the C: drive of the Windows system without root access, so I feel that this is a problem related to the mount point rather than mounting in general.

• MySQL - are FK's useful / viable in a web app?

  - by yoda

  Hi all, I've encountered this discussion related to FK's and web applications. Basically some people say that FK's in web applications doesn't represent a real improvement and can even make the application slower in some cases. What do you guys think, what's your experience? -- A quote from Heikki Tuuri, creator of InnoDB engine, founder and CEO of Innobase: InnoDB checks foreign keys as soon as a row is updated, no batching is performed or checks delayed till transaction commit Foreign keys are often serious performance overhead, but help maintain data consistency Foreign Keys increase amount of row level locking done and can make it spread to a lot of tables besides the ones directly updated

• Best sites to find good .NET Developers

  - by Mag20

  I am looking for good sites to post a position for a .NET developer. I already tried: Craig's list got about 10 resumes, but most couldn't answer our technical questions StackOverflow Careers no responses What sites did you have success with finding good developers? UPDATE 1: Wanted to provide some more information: My company is in NJ. We are a small startup. Less then 10 people. Monster, Dice, CareerBuilder all charge like $500 a month per posting. Seems a bit much. Also only Dice is specifically targeting technical positions. With monster and career builder I am a bit worried about having to go through hundreds of resumes that don't apply.

• Besides EAR and EJB, what do I get from a J2EE app server that I don't get in a servlet container li

  - by dacracot

  We use Tomcat to host our WAR based applications. We are servlet container compliant J2EE applications with the exception of org.apache.catalina.authenticator.SingleSignOn. We are being asked to move to a commercial J2EE application server. The first downside to changing that I see is the cost. No matter what the charges for the application server, Tomcat is free. Second is the complexity. We don't use either EJB nor EAR features (of course not, we can't), and have not missed them. What then are the benefits I'm not seeing? What are the drawbacks that I haven't mentioned? Mentioned were... JTA - Java Transaction API - We control transaction via database stored procedures. JPA - Java Persistence API - We use JDBC and again stored procedures to persist. JMS - Java Message Service - We use XML over HTTP for messaging. This is good, please more!

• No boot loader found - dual booting Windows 8 with Ubuntu 14.04

  - by Sriram

  I have been trying in vain to dual boot my computer with Windows 8 Pro (pre-installed) and Ubuntu 14.04 64-bit. I have been able to successfully install Ubuntu 14.04, but the option to start Ubuntu does not appear on startup. This is after having taken all steps as mentioned in Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported). I even tried the boot repair option and ended up with this error log. My questions are: How do I solve for No boot loaders found in /dev/...? Are there any other recommendations that will help me solve this? Other points that may be important: Booting into Ubuntu from a live USB shows all Ubuntu partitions on the hard drive.

• Skype does not save user configuration

  - by varsketiz

  On Ubuntu 10.10, I have recently started to experience this problem: For some reason Skype won't save any settings except "Sign in on startup". When Skype starts and tries to sign in it is unsuccessful (it shows incorrect password, in red) every time (I have provided the correct password). I always have to click to show contacts in groups, it does not remember it. Every time I have to go to options and update some notification settings. I know all these things should be "remembered" by Skype - this problem started only recently. I don't recall fiddling with any permissions that could have likely caused that. Do you know what the problem might be? I uninstalled (marking for complete configuration removal) and re-installed Skype, but it still remembers my username (why??). Can I find Skype configuration files on the filesystem somewhere and change permissions for them - or even better - edit the files to set what I want?

• How to make sure web services are kept stable from one release to the next?

  - by Tor Hovland

  The company where I work is a software vendor with a suite of applications. There are also a number of web services, and of course they have to be kept stable even if the applications change. We haven't always succeeded with this, and sometimes a customer finds that a service is not behaving as before after upgrading. We now want to handle this better. In general, web services shouldn't change, and if they have to, at least we will know about it and document the change. But how do we ensure this? One idea is to compare the WSDL files with the previous versions at every release. That will make sure the interfaces don't change, but it won't detect that the behavior changes, for example if a bug is introduced in some common library. Another idea is to build up a suite of service tests, for example using soapUI. But then we'll never know if we have covered enough cases. What are some best practices regarding this?

• Dual Boot Windows 8 UEFI and Ubuntu 12.10

  - by 0x4a6f4672

  I have got a new Samsung Series 7 laptop with Windows 8 where I tried to install Ubuntu. It is a 64-Bit system which uses UEFI and has "Secure Boot" switched on in the BIOS by default. After I switched if off (and set it to "UEFI and CSM OS") I was able to install Ubuntu (Ubuntu 11.10, which recognized Windows as Windows Vista, although it is Windows 8), by booting from CD with Settings/Change PC Settings/General/Advanced Startup in Windows 8. But after the installation and the restart of the machine somehow ignored Ubuntu and booted only Windows 8. Then I tried to reinstall Ubuntu 12.10. It still only boots Windows 8. Then I tried Boot Repair, which was not really helpful. Any ideas how I can create a dual boot system with Windows 8 and Ubuntu 12.10 ? Here is the link that Boot Repair generated: http://paste.ubuntu.com/1368624/ Is it necessary to create an extra EFI partition with GParted?

• How much code should I be responsible for?

  - by Mick

  Through colleagues and exit interviews, I have heard that at my small company I am "responsible" for anywhere from 3-10 times more code than I would be at another job. I'm trying to look for some sort of fuzzy metric that I can use to compare my workload with others in my field. By "code responsibility", I don't mean "I'm the only one who knows area X of the code base" (though sadly, it's often true in a startup environment), but rather am referring to a number like "code_base_size/number_of_developers". Are there any resources I can use to help me more accurately measure my work load than just counting lines of code?

• Collaboration platforms

  - by Thomas

  Are there any good collaboration platforms for game development? This would include the following features: Easy way to find various people you need to build games (programmer, artist etc) and forming a team like for example codeplex Online portfolio for users where they can offer their services (either paid or free) Posibility to create a game specific blog or site with social media integration to show the world what's being created Easy way to manage game content / resources with sufficient online storage, version control and if possible source control Manage all phases of game development (startup, creating concept, finding a team, creating proof of concept, production phase etc) and publish specific information for each phase also on social media etc. Manage asset creation flow (request for specific content like a sound, production of sound, uploading the sound, notification to the requester, implementation of the file, retouching in several cycles etc)

• Changing DisplayMode seems not to update Input&Graphic Dimension

  - by coding.mof

  I'm writing a small game using Slick and Nifty-GUI. At the program startup I set the DisplayMode using the following lines: AppGameContainer app = new ... app.setDisplayMode( 800, 600, false ); app.start(); I wrote a Nifty-ScreenController for my settings dialog in which the user can select the desired DisplayMode. When I try to set the new DisplayMode within this controller class the game window gets resized correctly but the Graphics and Input objects aren't updated accordingly. Therefore my rendering code just uses a part of the new window. I tried to set different DisplayModes in the main method to test if it's generally possible to invoke this method multiple times. It seems that changing the DisplayMode only works before I call app.start(). Furthermore I tried to update the Graphics & Input object manually but the init and setDimensions methods are package private. :( Does someone know what I'm doing wrong and how to change the DisplayMode correctly?

• Operating System for first production windows server code?

  - by Unkwntech

  I'm getting ready to purchase a server for me to deploy my first windows based (C# .NET) application but I'm not familiar with using windows for hosted applications. I have the choice of the following versions of windows: Windows Server 2003 Windows Server 2003 Web Windows Server 2003 Enterprise Windows Server 2008 Windows Server 2008 Web Windows Server 2008 Enterprise Would one of these be better for deploying a C# .NET application? EDIT: There will be 3 applications deployed but each will basically be the same, they will be services that are driven from data being brought in from a website that will likely run on the same server. http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx

• Xcode5 post-archive script for Sparkle package no longer works

  - by Flyingdiver

  Xcode 5 seems to have changed the way it stores the build application package (xxx.app) such that ditto no longer works. In the ../BuildProductsPath/Release/ directory, the app is actually a symlink to .../InstallationBuildProductsLocation/Applications/... MyApp.app - ~/Library/Developer/Xcode/DerivedData/MyApp-emwilkqhlayanxahjpexlpbbkato/Build/Intermediates/ArchiveIntermediates/MyApp/InstallationBuildProductsLocation/Applications/MyApp This breaks the ditto command I was using to create a zip file of the application to put on my Sparkle update server. Anyone have an updated script for building the Sparkle XML and ZIP files? Or know what environment variable I need to use to locate my actual binary after the Archive phase?

• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• Is Alpha Five Version 10 really all that its reported to be?

  - by Gary B2312321321

  I came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database devlopment tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding. The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?

• Chaning coding style due to Android GC performance, how far is too far?

  - by Benju

  I keep hearing that Android applications should try to limit the number of objects created in order to reduce the workload on the garbage collector. It makes sense that you may not want to created massive numbers of objects to track on a limited memory footprint, for example on a traditional server application created 100,000 objects within a few seconds would not be unheard of. The problem is how far should I take this? I've seen tons of examples of Android applications relying on static state in order supposedly "speed things up". Does increasing the number of instances that need to be garbage collected from dozens to hundreds really make that big of a difference? I can imagine changing my coding style to now created hundreds of thousands of objects like you might have on a full-blown Java-EE server but relying on a bunch of static state to (supposedly) reduce the number of objects to be garbage collected seems odd. How much is it really necessary to change your coding style in order to create performance Android apps?

• Why does my health bar disappear whenever my character takes amage?

  - by iQue

  Im making health bar for my game that looks like this: public void healthBar(Canvas canvas) { float healthScale = happy.getHP() / happy.getMaxHP(); Rect rect = new Rect(20, 20,(120 * (int)healthScale), 40); Paint paint = new Paint(); paint.setColor(Color.RED); canvas.drawRect(20, 20, 220 * healthScale, 40, paint) } this is called every time my game renders. When the game starts it's where I want it, but as soon as my character (happy) takes any damage, it dissapears. And I know that his hp only gets subtracted by 5 every time he gets hit. So this should not happen? example: @Startup: happy.getHP() == 100, happy.getMaxHP == 100. when damaged HP -=5, -> happy.getHP() == 95 -> healthscale == 0,95 -> 220 * 0,95 == new width for Rect(?)
