• Xubuntu all Icons disappeared

  - by user1392185

  I'm running Xubuntu 12.04.1 with kernel Xen4.1-amd64 and the following problem is mine: Nearly all icons have been replaced by the default "no icon available"-icon, even on the login screen and the all icons in software like e.g. Firefox and the icons I manually assigned to launchers, too. Changing the icon theme does not seem to affect this. The only icons that did not disappear are: LibreOffice, gThumb, Simplescan, Ristretto and in the XFCE menu office, tools and graphics. How could I bring the icons back? EDIT: When I tried to use Ristretto the following error showed up: Could not load image-loader module /usr/lib/x68_64-linux-gnu/gdk-pixbuf-2.0/2.12.0/loaders/libpixbufloader-png.so Unable to open shared-object-file I/O error (Had to translate this to English.)

• Cannot type '^' (caret) in native KDE apps

  - by nebukadnezzar

  I cannot type the caret character '^' in native KDE apps, such as plasmoids, editors (Kate, KWrite), etc. It worked in previous (older) versions of KDE (3.5, I think). I believe it may be related to the fact that I'm using a keyboard with a german layout, however, it would seem farfetched - I can type the caret character just fine in non-KDE apps (such as chrome, firefox, etc). I tried switching keyboard layouts, but no cigar. What's going on? What do I have to change to get the caret character back?

• Rollback in Oracle and SQL Server

  - by CatherineRussell

  I have an Oracle background. It was interesting to see how rollback handled in Oracle and SQL Server. There is no begin trans in Oracle.  What oracle does is it will store the data in a temporary area called the rollback segments. Untill your issue the commit command the records will be kept there. You can even rollback your update statement by issuing the rollback command. When you issue the commit command the records in the rollback segments are written to the redo log files. The same logic for insert is also applicable except that there is no mirror image of the record kept.   In SQL Server, if you want to be able to roll back statement, you neet to start your statement with a "begin tran" . Then, you can rollback a transaction, if this is needed. begin tran update Person set FirstName = 'Arthur' where PersonId = 10 -- select firstname from Person rollback

• error: you need to load kernel first

  - by Angelos318

  I made a clean install on my Sony Vaio laptop, of Ubuntu 11.10 and when the installation was ready, it prompted to remove the usb I was installing the distro from, and press enter to reboot. After this reboot the first thing I got was the following error: error: couldn't read file error: you need to load the kernel first Press any key to continue.. After that it throws me back to the Grub select screen: Ubuntu, with linux 3.0.0-14-generic-pae recovery mode previous linux versions (none since I made a clean install) memory test If i choose the first option it shows only a black screen and never loads anything. If i reboot the same thing happens. Could I repair this using boot-repair? Is there any other way? Note: I know nothing about linux code so i am a total noob on this one Update: boot-repair did not help Grub.cfg here: http://pastebin.com/GKLuDuhM Boot Info Script: http://pastebin.com/indARkKJ

• How to obtain a list of installed packages based on a backup?

  - by ujjain

  I have made a backup of my entire computer and I reinstalled the OS right now. I know I should have listed dpkg -l to obtain a list of packages, but I have not done so. I only made a tarball of the entire disk. I wonder how I can find a list of packages based on this data. I would like to have the same packages installed that I had on my previous set-up. But there seems no longer a way to gain a list of packages, since I already reinstalled Ubuntu on the computer and only have the tarball back-up.

• Unleash the Power of JavaFX

  - by Angela Caicedo

  It seems that it was just yesterday that we were getting ready for JavaOne 2012.  Now it's over, but it's definitely a great time to go back and watch the sessions you missed, and learn some of the latest news about Java.   For this JavaOne, I presented two sessions and one HOL, all of them related to JavaFX: JavaFX Extreme GUI Makeover Building JavaFX Interfaces with the Real World Unleash the power of JavaFX If you couldn't join us for these sessions, just follow the links and you can watch the videos on demand. For the HOL I've created a repository at GitHub, as many of the attendees wanted to keep the material.   In this repository you can find the lab document, the NetBeans projects for each exercise and it's appropriate solution.  Hope you enjoy! I created and presented a HOL called:  Unleash the power of JavaFX.  In this blog entry I would like to provide you

• Openjdk-7-jdk some commands not recognized?

  - by function

  I installed openjdk-7-jdk using apt-get install. However, when I type 'javac', the terminal says, 'bash: /usr/bin/javac: No such file or directory'. I think the link is broken, but how can I fix it? Note: I installed openjdk-7-jdk before, but then I removed openjdk and installed sun-java. Now I deleted sun-jdk and want to go back to openjdk, but javac is not recognized. I'm using Ubuntu 11.10. Edit: Recognized: java; Not Recognized: javac, javadoc, appletviewer, ...

• What do you do when one thinks the code isn't complicated enough?

  - by Chris

  After six months of development on a project, our stakeholders have had a "gut check" and have decided that the path that we've been walking (a custom designed application framework and data access layer) is holding us (the developers) back from quickly developing the features they would like to see. After several days of debate management and the development team have decided to scrap the current incarnation and start over using ASP.net MVC, with Entity Framework as the bases of the a 'quick and dirty', lets just get it done project. In days following, our senior developer who has never worked with MVC or Entity Framework has finally gotten into a sample project and done some work. His take on ASP.net MVC, "this is not software engineering". So my question is this; what do you do, when one doesn't think the code is complicated enough?

• SQL Server 2008 R2: StreamInsight changes at RTM: Event Flow Debugger and Management Interface Secur

  - by Greg Low

  In CTP3, I found setting up the StreamInsight Event Flow Debugger fairly easy. For RTM, a number of security changes were made. First config: To be able to connect to the management interface, your user must be added to the Performance Log Users group. After you make this change, you must log off and log back on as the token is only added to your login token when you log on. I forgot this and spent ages trying to work out why I couldn't connect. Second config: You need to reserve the URL that the...(read more)

• DrRacket icon doesnt work?

  - by Laurie

  I installed DrRacket from the Ubuntu Software Center. All went well and an icon appeared however nothing happened when I clicked the icon so I removed it.

The DrRacket icon came back in Dash Home but again clicking it nothing appears to happen. How do I start DrRacket? I am running Ubuntu 12.04 LTS dual boot on a 64 bit Dell

• Problems with NAT Adapater since upgrade to Ubuntu 12.10

  - by jjesse

  I was running Ubuntu 12.04 w/ VirtualBox installed. I was using the NAT interface to connect to everything. Basically running VBOX for testing some things and a Windows VM for Netflix.. Was back to working in my VMs today and noticed that I was unable to connect to the internet. In the VM settings I'm using the NAT adapter, however I noticed there is no NAT adapter in the Network Settings under Preferences in VBOX. Not quite sure what happened but wonder what is going on? I noticed there are some posts about changes DNSMASQ and configuring a bridge mode, but this worked out of the box under 12.04 and since the upgrade this no longers work. Need some help please

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• What is the relevance of resumes in the age of GitHub, Stack Exchange, Coursera, Udacity, blogs, etc.?

  - by davidk01

  My resume is no longer relevant. It can no longer contain an adequate description of my technical abilities. One can get a much better sense of what I am capable of by looking at my GitHub repositories, my Stack Exchange profiles, and the various courses that I am taking at Udacity and Coursera. The problem is that I have no idea how to tell employers that those are the places to look if they want an accurate description of what I can do. Every time a recruiter contacts me I gently nudge them towards all the resources I just mentioned and I also provide a link to a publicly visible Google doc that contains my resume along with links to all those resources. Yet, they keep coming back asking for a more descriptive resume. How can I make it even more blatantly obvious that if somebody wants to hire me then they can save themselves a whole bunch of trouble by just clicking on a few links and browsing around?

• How can I have a Bluetooth Keyboard Auto-Connect at Startup?

  - by Grant

  I have a bluetooth keyboard for my HTPC. I pair it with my computer via bluetooth, and it works fine. However, when I turn off the keyboard or my computer, it has to connect again (which requires me entering a passcode on the computer and keyboard) when I turn them back on. I've looked through many forums and through that I have found that I'm missing some seemingly vital bluetooth files: /etc/default/bluetooth /etc/init.d/bluetooth /etc/bluetooth/hcid.conf In the instructions that I've found online so far, I must change certain lines in any of these files. I am unable to, since they do not exist. Am I missing a dependency or something? I've also tried installing Blueman but that didn't help at all. I'm running Ubuntu 10.10 (Maverick). Original post: http://ubuntuforums.org/showthread.php?t=1643386&highlight=bluetooth

• Ubuntu multiple issues (blank screen)

  - by Donavon

  Computer Specs I am having difficulties, to get Ubuntu 11.10 to work. For the 11.10 version, if I click install, or if I click try Ubuntu, I only get a blank screen, that just stays there. If I use "nomodeset", it changes to a loading screen and after about 2 minutes it goes back to black screen - however, before it goes black, i get a few errors, like: bad target number, or passwd error mode (something like that). I've also tried (xforcevesa, i915.modeset=0, nomodeset, radeon.modeset=0, i915.modeset=1) I have also tried the alternate installation, which installed fine, however when I boot up, select it from "grub", it goes black. I did manage to install 10.04, however the screen resolution was 800x600 and I couldn't fix it to 16:9 (my resolution). I don't wanna use 10.04, because I would like the new one 11.10, and would like to use it. Any help would be GREATLY appreciated. Thank you

• Compiz window decorator randomly disappears

  - by adjfac

  I know people have posted this problem before such as http://askubuntu.com/users/authenticate/?s=9b515fe8-5da2-4bb9-ba01-dcea538b9b9c&dnoa.userSuppliedIdentifier=https%3A%2F%2Fwww.google.com%2Faccounts%2Fo8%2Fid&openid.mode=cancel&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0 but i am looking for a more permanent solution right now. It happens to me at least once a day and when that happens, I usually go to compiz, uncheck and check window decorator and it will bring it back. But it's sort annoying and just wonder if there is a permanent fix out yet? I am using gnome (not unity), on a bran-new thinkpad t520.

• The Return of Oracle Wikis: Bigger and Better

  - by oracletechnet

  The Oracle Wikis are back - this time, with Oracle SSO on top and powered by Atlassian's Confluence technology. These wikis offer quite a bit more functionality than the old platform. For example, wikis are now associated with groups/spaces, as opposed to an open free-for-all, and space owners have curative responsibility (for approving new members, moderating comments, and so on). All in all we're confident that you will be pleased with the experience. Of course, we'll be on the hunt for bugs/issues for a while, and if you find any yourself we encourage you to report them here.

• Most effective marketing strategy to promote a casual iOS game?

  - by user1114968

  So I posted this on another forum yesterday but that forum got suspended for malware so gotta wait for the webmaster to fix the site. Here's the basics: We've released a press release through PRMac that included a video review. Submitted and followed up on all the big iOS review sites. None of them replied back with interest. A lot of them just told me that their editors are volunteers who will review games that are "interesting to their readers" and that they would put my app "into consideration" The only site that reviewed our app and promoted virally was iPhoneAppReview.com which we paid. We promoted on the top iOS forums We are now doing in-app advertising through inMobi and are integrating the SDK code into our app to start doing Tapjoy We posted up our gameplay videos on YouTube Any marketing strategies that anyone can suggest or recommend that we haven't used yet? If anyone wants to try out our game and give feedback on the game or the site or anything, that would be great! Our target countries are Japan, China, and the US.

• Did Google Delete my index?

  - by Sei

  I have a website that I haven't had much time to take care of. I updated it 4 times since last October, the contents are all original and informative. I can see those cache from Way back Machine and the site was indexed in Yahoo, but not in google. Did I get my index on Google deleted because I did not update it often? Normally Google crawl often and index fast, I just got really worried if I did something wrong. Is it possible that I set something wrong in the hosting or something? Please help me

• How best to take a users signature online? (UK law orientated) [closed]

  - by Ben Griffiths

  Not sure if this is the best place to ask, but I can't seem to find any of the other SE sites that would fit better (unless there's a law one?) I'm building an application that will replace an existing paper based form, and this form would normally be signed by the person filling it in. Looking around, it's hard to find a good definitive resource to explain what I can and cannot accept as far as a signature goes. It looks like some UK government online forms accept just your name typed into a box, but I've also heard you should back up with an email - so that process would be type name into a box along with providing an email address, send out an email, then make them click a link within the email to finally complete the verification. Involving email seems very long winded and leaves the system open to spam filters blocking emails, forgotten emails that just sit in inbox's etc. So, does anyone have any knowledge in this department? Personally, I'd love to just get them to type their name into a box and be done with it!

• How do I get Catalyst 11.10 with ATI Radeon Mobility HD 5470 working on an HP DV7?

  - by S Kumar

  I have a HP DV7 with a HD 5470 512M card. Installation of the Catalyst 11.10 is repeatedly failing on a fresh install of Ubuntu 11.10. Catalyst 11.8 proprietary drivers were working well with Ubuntu 11.04. I have tried installing directly from the .run and generating the distribution specific packages. Nothing has worked. After installation which goes through successfully, the system hangs on reboot after the flashing dots. I have to replace the /etc/X11/xorg.conf to get the X working. I have followed instructions as per the http://wiki.cchtml.com/index.php/Main_Page wiki. Request for support to ATI/AMD gives the response that this model is unsupported on Linux by HP :). Updated 14-Nov I have reverted back to the open source drivers which work well enough for me.

• Why is my content database so large?

  - by PeterBrunone

  If your SharePoint site collection hasn't grown, but your content database has, the most likely culprit is versioning.  If a list -- or worse, a library -- has versioning enabled, the default is to keep every single one.  That means that every time someone edits and checks in a document, its storage footprint increases by the size of the document (and probably a little more).The solution?  It could be a bit painful, but you'll need to go back into each library and restrict the number of versions to keep (three is sufficient for most uses, but your needs may vary).  I suggest keeping only major versions as well, since minor versions are really just stopping points on the way to a published document.Of course if you have a real business need to keep all those versions around, then you'll want to look into an archiving solution that will take the old versions out of the content database but still make them available if necessary.
