• Unable to install MS Office, wine1.7, and getting updates

  - by spirit

  I am a new ubuntu user, just installed 12.04 LTS. Learned a lot from ubuntu users suggestions on the webs. I am a student and frequent user of MS office. However, I am unable to install MS Office as failing to get updates plus installing wine1.7. sudo apt-get update shows something about unable to connect archive.ubuntu.com and some files failed to download, they have been ignored or older ones have been used instead. sudo apt-get install wine1.7 shows something about unmet dependencies and broken packages.

  - by user205996

  I really searched for information to this problem but none of the guides or threads on forums have helped, either i cant search or this havent come up. No nomodeset, forcevesa, turning brightness up or anything have worked.... I bought the laptop with ubuntu 13.04 preinstalled, bumblebeedrivers were on it but primusrun broke on the ubuntu 13.10 update.

• How do I allow Ubuntu to use more space on my computer?

  - by anonymous

  Ubuntu currently won't use more than 4GiBs on my computer, but I need more space. My computer can hold much more than 4GiBs. How do I allow Ubuntu to use more? Please give step-by-step instructions in plain English. Update: I'm referring to my Ubuntu operating system. I installed it using Wubi through Microsoft Windows. I deleted Wubi from my Windows desktop after installation. All I want is to expand my Ubuntu operating system. I plan to gradually transition from Windows to Ubuntu and so I'll need to transfer more files and programs from Windows to Ubuntu in the future. Right now, I already need more GiBs for Ubuntu. I can barely use Ubuntu right now because there's almost no space left. I simply want Ubuntu to use what space I need it to use. People, please quit complicating this issue and inform me how to make Ubuntu use more space.

• How can a regular user be notified of a required reboot?

  - by Andre

  I am administrating multiple machines on which I am admin and the users have not admin-rights. The machines are configured to pull and install updates automatically. A new kernel will require a reboot. On Ubuntu Precise this was made visible to the user through the color change of the shutdown-menu in the upper right corner (it turned red). Now, on Ubuntu Trusty, there is not color change anymore. Also, the Update Manager will not pop up for regular users reminding them of an outstanding reboot. How can a regular user know that a reboot is required?

• Blank Screen ... No Bios Loading Screen Either

  - by SwissStar

  I don't even know how long it's been but I had given up. until now. My screen does not come on AT ALL, not even and the Bios loading screen. I have to connect it to my TV in order to see. But there's one thing that has always started it back up, and that is by running a hard ware Diagnostics * Provided by DELL* . It is definitely has something to do with Ubuntu. I know that for sure, because I remember running an update and BAM . That was it for the screen. How could I restore my screen back to Life ? I have a Nvidia Graphics Card.

• Internet (HTTP) is not working on Sony Viao

  - by vijay

  I switched my sony viao laptop from XP to ubuntu 10.04 recently. I have it connected through router at home. The internet was working fine with XP. With ubuntu, i am not able to connect to interenet. I am able to update using apt, and i am able to ping too. It seems like there is a DNS issue, when i try to goto sites from firefox, it doesn't work. I tried disabling the ipv6 in firefox config, it doesn't work. My router is on 192.168.2.1 instead of 192.168.1.1 any ideas on what config i might need to change to make this work? or could this be a drive issue?

• WiFi is painfully slow, sometimes stops altogether

  - by Zelda64fan

  Lately my WiFi connection has been quite slow, and sometimes I lose my internet connection altogether (but the computer does not actually disconnect from the WiFi network). This only affects my laptop and only when it's running Ubuntu, so I think it must be a problem with Ubuntu. I haven't changed anything recently; this is on 12.10 64-bit. What could it be? Update: It's doing this now. The connection isn't completely dead, it's just staying under 5 kB/s. Still frustrating though. It also seems to affect all users.

• Announcing an Upgrading How-To Technical Paper for WebLogic 11g

  - by Oracle Retail Documentation Team

  Oracle Retail has published a document on My Oracle Support (https://support.oracle.com) that provides you with guidance on how to upgrade from WebLogic11g 10.3.3 to WebLogic11g 10.3.4. The goal of this document is not to be a substitute for WebLogic documentation but to illustrate how Oracle Retail approached and performed its upgrade.   Doc ID: 1432575.1This document provides information about how to upgrade to WebLogic 10.3.4 and how to complete related component upgrades as well. Upgrading from WebLogic 10.3.3 to WebLogic 10.3.4 (rather than performing a separate WLS 10.3.4 installation) is recommended so that you do not have to port information and custom settings from your 10.3.3 installation. The paper addresses the following topics: High Level Steps for Applying WLS 10.3.4 Patch and 1.1.1.4.0 Patch Set JRockit Upgrade (optional for Linux and Sun OS only) WLS 10.3.4 Upgrade using Upgrade Installer SOA 11.1.1.4 Upgrade Forms 11.1.1.4 Upgrade Update DB Patch Assistant Post Patch Instructions Validation

• Random Cache Expiry

  - by mahemoff

  I've been experimenting with random cache expiry times to avoid situations where an individual request forces multiple things to update at once. For example, a web page might include five different components. If each is set to time out in 30 minutes, the user will have a long wait time every 30 minutes. So instead, you set them all to a random time between 15 and 45 minutes to make it likely at most only one component will reload for any given page load. I'm trying to find any research or guidelines on this topic, e.g. optimal variance parameters. I do recall seeing one article about how Google (?) uses this technique, but can't locate it, and there doesn't seem to be much written about the topic.

• Entity Framework, Code First: where is the database?

  - by Marko Apfel

  With Entity Framework 5 in Visual Studio 2012 the code first feature could let you come to the question “Where is the automatically created database located?” I run in the question after changing the model which throws during the next run this error: “The model backing the 'MyContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).” Okay – clear I thought “delete the database”. But where is the database and what type is it??? In this constellation the frameworks generates a localDB. You could access this database via SQL Server Object Explorer. For the first time you have to add this localDB. The server name is “(localdb)\v11.0”: And so we could browse through the content of this database. It got the same name like the context class.

• SDL: How would I add tile layers with my area class as a singleton?

  - by Tony

  I´m trying to wrap my head around how to get this done, if at all possible. So basically I have a Area class, Map class and Tile class. My Area class is a singleton, and this is causing some confusion. I´m trying to draw like this: Background / Tiles / Entities / Overlay Tiles / UI. void C_Application::OnRender() { // Fill the screen black SDL_FillRect( Surf_Screen, &Surf_Screen->clip_rect, SDL_MapRGB( Surf_Screen->format, 0x00, 0x00, 0x00 ) ); // Draw background // Draw tiles C_Area::AreaControl.OnRender(Surf_Screen, -C_Camera::CameraControl.GetX(), -C_Camera::CameraControl.GetY()); // Draw entities for(unsigned int i = 0;i < C_Entity::EntityList.size();i++) { if( !C_Entity::EntityList[i] ) { continue; } C_Entity::EntityList[i]->OnRender( Surf_Screen ); } // Draw overlay tiles // Draw UI // Update the Surf_Screen surface SDL_Flip( Surf_Screen); } Would be nice if someone could give a little input. Thanks.

• Black screen on Ubuntu 12.04

  - by user1648371

  I've just upgraded to Ubuntu 12.04 and I'm experiencing some problems. The first thing I noticed is that when I click the Workspace switcher all I get is a black screen (I can guess where the different workspaces are located and clicked on them, not a practical solution though). In addition when I lock the screen or suspend the laptop (a Vaio VPCEB4M1E) I get a shifted screen (I see the right most vertical stripe on the left size of the monitor and nothing about all the rest, to put it clearly I can see the gear that allows me to turn the pc off, etc, but not much more..) when I go to the additional driver menu I see the "ATI/AMD proprietary FGLRX graphics driver" are installed and the post-release update version is available. I don't know if the problem is driver related, so before doing anything I'd like to get some suggestions from you guys. Thanks you!

• Networking Icon Keeps Disappearing

  - by Zelda64fan

  Almost every time I unlock my computer the networking icon and the Bluetooth icons are missing from the panel. They also disappear if I disable networking with the 'hardware switch', even though before they would just switch to a 'disabled' look. I know I can get the networking one back by running nm-applet, but I'd rather just find a way to make it stop disappearing. What causes this? This is on 12.10 64-bit, if it matters. UPDATE: I ran it from terminal, and got this: $ nm-applet ** Message: applet now removed from the notification area ** Message: PID 31340 (we are 28924) sent signal 15, shutting down... And then it exited. So it thinks it's supposed to quit...? I haven't been able to figure out what process had that ID.

• ubuntu 12.04 sound not working in applications

  - by user109887

  I run Ubuntu on a DELL Vostro 3500 laptop. Everything was working perfectly since this morning, after an update... I can't play any multimedia sound anymore, that includes youtube and others, mp3 in Rythmbox, sound of video in VLC. I can see my device in the setting window and I can play tests sound, but nothing else. Any idea? EDIT: I'm switching very often from to HDMI output, which is deconnected right now. I've tried running VLC, and in the audio menu, you can choose the output so now I can listen to music via VLC but not with other programs. Looks like ubuntu is not totally switching the audio device after unplugging the HDMI cable. Is there any command line which can do so?

• How to avoid movement speed stacking when multiple keys are pressed?

  - by eren_tetik

  I've started a new game which requires no mouse, thus leaving the movement up to the keyboard. I have tried to incorporate 8 directions; up, left, right, up-right and so on. However when I press more than one arrow key, the movement speed stacks (http://gfycat.com/CircularBewitchedBarebirdbat). How could I counteract this? Here is relevant part of my code: var speed : int = 5; function Update () { if(Input.GetKey(KeyCode.UpArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } else if(Input.GetKey(KeyCode.UpArrow) && Input.GetKey(KeyCode.RightArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } else if(Input.GetKey(KeyCode.UpArrow) && Input.GetKey(KeyCode.LeftArrow)){ transform.rotation = Quaternion.AngleAxis(315, Vector3.up); } if(Input.GetKey(KeyCode.DownArrow)){ transform.Translate(Vector3.forward * speed * Time.deltaTime); } }

• How should I define my Java Objects?

  - by HonorGod

  I have a data grid where I sort of show the following information - All Guests Total Adults = 22 Total Children = 27 Confirmed Total Adults = 9 Total Children = 13 Country = Germany Total Adults = 5 Total Childres = 6 Friends Adults = 2 Children = 2 Relatives Adults = 3 Children = 4 Country = USA Total Adults = 4 Total Childres = 7 Friends Adults = 2 Children = 5 Relatives Adults = 2 Children = 2 Tentative Total Adults = 13 Total Children - 14 Country = Australia Total Adults = 7 Total Childres = 8 Friends Adults = 2 Children = 3 Relatives Adults = 5 Children = 5 Country = China Total Adults = 6 Total Childres = 6 Friends Adults = 2 Children = 4 Relatives Adults = 4 Children = 2 And in the database what I have is data at the lowest level which is Friends / Relatives and the corresponding countries set as a look-up value which in indirectly connected to another look-up that can tell me if they fall under confirmed or tentative. I guess my question is how do I layout my Java Object and perform the aggregations and give it back to the client. I am not sure if I am clear with my question, but feel free to comment so I can update the question accordingly.

• E-Mail Center: How to Debug Auto-Processing Issues

  - by LuciaC

  Do you use E-mail Center Auto-Processing functionality?  Auto-processing rules can be defined which will process an email and initiate actions such as sending an auto-reply, auto-acknowledgement or service request update or creation.  If you're using auto-processing in your environment, then you will have noticed that, when things go wrong, often the only indication that there is an issue is if the email goes to the Supervisor Queue for manual processing instead of being sent.  Oracle Development has developed a script to help you debug when an email is meant to be auto-processed but is failing. There are scripts for R12.0.6 through to R12.1.3. See Doc ID 1427925.1 for details of the script and how to use it.

• Comparisons of Javascript 'data grids'?

  - by Joe

  I've found plenty of questions between here and StackExchange of people asking for the 'best' data grid / data table, or one that has a particular feature, and plenty of lists out there (of various ages) listing the various data grid implementations ... but is anyone aware of any matrix of what features the various solutions implement? (eg, allow shift-click to select multiple; support checkboxes for selection; can update a regular table in-place; allow editing of cells; support websql or indexeddb for local caching; which browsers they support; infinite scroll; etc.) There's a generic 'javascript framework' comparison on wikipedia, which would be the sort of thing I'm looking for, but it doesn't go into detail on data grids. (which makes sense, as so many are extensions, not core features of those frameworks, and in the case of jQuery, there's lots of 'em.)

• How can I track a falling ball with a camera?

  - by Jason

  I have been trying to get my camera to follow a falling ball but with no success. here is the code float cameraY = (FrustumHeight / 2)+((ball.getPosition().y) /2) - (FrustumHeight /2); if (cameraY < FrustumHeight/2 ) cameraY = FrustumHeight/2; camera.position.set(0f,cameraY, 0f); Gdx.app.log("test",camera.position.toString()); camera.update(); camera.apply(Gdx.gl10); batch.setProjectionMatrix(camera.combined); batch.begin(); batch.draw(backgroundRegion, camera.position.x - FrustumWidth / 2, -cameraY - (FrustumHeight/2) , 320, 480); batch.draw(ballTexture, (camera.position.x - FrustumWidth / 2) + ball.getPosition().x,-cameraY + ball.getPosition().y - (FrustumHeight/2) , 32, 32); I'm sure I am doing this completely wrong - what is the correct way to do this?

• Ubuntu 12.04 x64 doesn't boot anymore after a power failure

  - by Felix

  I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive?
