  • Ubuntu 11.10 won't boot on Dell XPS 8300

    - by Phil Gorman
    I have a brand new Dell Studio XPS 8300 desktop with 17-2600 cpu, H67 chipset, 8GB DDR3, 2 1TB HDDs in mirrored RAID, and AMD Radeon 6770. Dell doesn't support Ubuntu here in Australia so it came with Windows 7 and Windows software. Yes I had to pay for an O.S. and software I didn't want to get hardware I did want, all at a greatly inflated price. It's not all beer and skittles in the land of Oz. I changed boot priorities in the BIOS to DVD and ran Ubuntu 11.10 64bit from the ISO with NOMODESET. The installation reformatted all partitions to rid me of the dreaded Windows. All was well until until reboot. The BIOS does its thing, then its "The Black Screen of Death" with a blinking cursor; no boot screen, no Grub, no keyboard, no mouse. I've searched Dell and Ubuntu forums in vain. Can you help? I would be really grateful for any advice which can help turn my big expensive paperweight into a really useful machine. Thank you in anticipation kind people. Phil

  • ecryptfs - decrypt and mount at boot with USB key

    - by Josh McGee
    I have a system running Ubuntu Server as a testbed for some services that I want to get familiar with. I decided to let the installation procedure set up encryption. I knew all along that I would have to decrypt it with the passphrase in order to get the system booted, but I assumed it wouldn't matter since it will only boot once or twice a month. However, my brother has informed me that he is a victim of power outages at the residence where this server is located. This means we have to explain to his girlfriend how to turn on the computer, attach a keyboard, connect a monitor (she just can't understand that she can type to the computer without a display, so whatever) and input the passphrase for us, while we are at work. I have arrived at the conclusion that I should just put together a USB key that can be plugged in before powering on the computer, to avoid all the trouble. Is this possible with ecryptfs? Is there a tutorial or simple list of instructions available so that I can knock this out and focus back on the stuff I care about? EDIT: I am aware that this is possible with LUKS and dm-crypt, but unfortunately the magical encryption that Ubuntu hands you during the installation is only ecryptfs so my question is specific to that.

  • 10 Tech Products Ahead of Their Time [Video]

    - by Jason Fitzpatrick
    Sometimes a product just can’t help but be too far ahead of it’s time to be adopted. Check out these 10 products that had their moment of glory a moment (or a decade) too soon. At Mashable they’ve gathered up 10 products that hit the market too soon for people to really appreciate them. Among them, as seen in the video above, a super simple internet-focused computer. At the time it hit the market people simply didn’t get the value of having a cheap, easy to use internet terminal. It probably didn’t help much that the 1990s internet didn’t have the plethora of powerful and useful web-based applications we have now. None the less we now have tons of lightweight and “underpowered” devices focused on the internet experience (like netbooks, iPads, smart phones, chromebooks, and more). Hit up the link below to see the 9 other gems from their collection of products ahead of their times. 10 Tech Products Ahead of Their Time [Mashable] How to Make and Install an Electric Outlet in a Cabinet or DeskHow To Recover After Your Email Password Is CompromisedHow to Clean Your Filthy Keyboard in the Dishwasher (Without Ruining it)

  • Is /home encryption useful on a server?

    - by Dennis
    I've got a question about the use of encryption: I set up a Ubuntu 12.04 server to use it as a router, file server for backups and webserver. Of course, it is probably not the best idea to put backups on the same system as a web server, but it is only for private usage and I don't want to spend too much money. So I thought it is not a bad idea to set up /home-encryption for the backup-user-account with which I do my backups. But in the same moment, another quesiton arises: Does it still makes sense? Via SSH, root login is disabled. And access to the /home-folder of that user is reduced to the user itself. So the only scenario to access the /home-folder is to connect keyboard/display to the server, login as root and change to /home. Or have I overseen a scenario? In case I am right, you can only access the /home-folder from "outside" as the backup-user. But than, encryption also doesn't make sense anymore. Am I right about that thoughts? Or do you still see a way to access the /home-folder of the backup user so that encryption still makes sense? Thanks for your help in advance!

  • Nexus 7 Possibly Bricked

    - by user214186
    I have a 1st gen Nexus 7 (32GB). I used the steps at https://wiki.ubuntu.com/Nexus7/Installation to successfully install Ubuntu 13.04 desktop onto the tablet. It was working fine and then I decided to upgrade to Ubuntu Touch. I booted the tablet into fast boot mode but the commands 'adb devices' and 'sudo fastboot devices' would not see the device. I am performing these steps from an Ubuntu 12.04 desktop PC. Prior to installing 13.04 the device was seen fine. I made the mistake of performing the 'Device factory reset' step from https://wiki.ubuntu.com/Touch/Install - Step 2. Now when I try to boot the device I get the following: mount: mounting /dev on /root/dev failed: no such file or directory mount: mounting /dev on /root/sys failed: no such file or directory mount: mounting /proc on /root/proc failed: no such file or directory Targe filesystem doesn't have requested /sbin/init. No init found. Try passing init= bootarg. BusyBox v1.20.2 (Ubuntu 1:1.20.0-0ubuntu1) built-in shell (ash) Enter help for a list of built-in commands. (initramfs) I have searched the web but every reference to this problem is from people who still have ADB access to the device so they can recover by flashing the tablet again. I can attach a keyboard to the USB port and access the BusyBox console but I don't know what steps to do to recover from my error. Any suggestions would be helpful. Thanks

  • How to Uninstall Internet Explorer 10 in Windows 8

    - by Taylor Gibb
    We previously explained why so many geeks hate Internet Explorer, and even though Internet Explorer 9 and 10 are greatly improved, and on par with the competition, we’re still going to explain how to uninstall it from Windows 8 if you should want to do so. Uninstalling Internet Explorer 10 Press the Win + R keyboard combination and type appwiz.cpl into the run box, then hit enter. When the Programs and Features window opens, you are going to want to click on the “Turn Windows features on or off” hyperlink on the left hand side. Next, find Internet Explore and uncheck it. You will then be given a warning, you can just click yes to continue. Now click on the OK button, and then reboot your machine. Once you machine has restarted, you will see that Internet Explorer is no longer in the taskbar You should also notice that the Metro version of Internet Explorer has also been removed. That’s all there is to it.

  • CPU Wars Is a Trump-Style Card Game Driven by Chip Stats

    - by Jason Fitzpatrick
    If you’re looking for the geekiest card game around, you’d be hard pressed to beat CPU Wars–a top-trumps card game built around CPU specs. From the game’s designers: CPU Wars is a trump card game built by geeks for geeks. For Volume 1.0 we chose 30 CPUs that we believe had the greatest impact on the desktop history. The game is ideally played by 2 or 3 people. The deck is split between the players and then each player takes a turn and picks a category that they think has the best value. We have chosen the most important specs that could be numerically represented, such as maximum speed achieved and maximum number of transistors. It’s lots of fun, it has a bit of strategy and can be played during a break or over a coffee. If you’re interested, you can pick up a copy for £7.99 (roughly $12.50 USD).

  • Tinkerforge Rotation/LCD & JavaFX Plans

    - by Geertjan
    The first time I integrated two Tinkerforge bricklets, the day before yesterday, was pretty cool: import com.tinkerforge.BrickMaster; import com.tinkerforge.BrickletLCD20x4; import com.tinkerforge.BrickletRotaryPoti; import com.tinkerforge.IPConnection; import java.util.Calendar; public class TFConnectionDemo { private static final String HOST = "localhost"; private static final int PORT = 4223; private static final String MASTERBRICKUID = "somethingabc"; private static final String LCDUID = "somethingabc"; private static final String ROTIUID = "somethingabc"; private static IPConnection ipc; private static BrickMaster master = new BrickMaster(MASTERBRICKUID); private static BrickletLCD20x4 lcd = new BrickletLCD20x4(LCDUID); private static BrickletRotaryPoti poti = new BrickletRotaryPoti(ROTIUID); public static void main(String[] args) { try { ipc = new IPConnection(HOST, PORT); ipc.addDevice(master); ipc.addDevice(lcd); ipc.addDevice(poti); poti.setPositionCallbackPeriod(50); poti.addListener(new BrickletRotaryPoti.PositionListener() { @Override public void position(short position) { lcd.clearDisplay(); Calendar cal = Calendar.getInstance(); lcd.writeLine((short) 0, (short) 0, cal.getTime().toString()); lcd.writeLine((short) 1, (short) 0, "Rotation: " + position); } }); } catch (Exception e) { } } } The result is that the display text in the LCD bricklet changes while I turn the rotation bricklet: Now imagine that you have some JavaFX charts and, while you turn the rotation bricklet (i.e., the dial thing that I'm turning above), the values of the charts change. That would be pretty cool because you'd be able to animate the JavaFX charts by rotating an object externally, i.e., without even touching the keyboard. That would be pretty cool to see and shouldn't be hard to implement.

  • Calculating collision force with AfterCollision/NormalImpulse is unreliable when IgnoreCCD = false?

    - by Michael
    I'm using Farseer Physics Engine 3.3.1 in a very simple XNA 4 test game. (Note: I'm also tagging this Box2D, because Farseer is a direct port of Box2D and I will happily accept Box2D answers that solve this problem.) In this game, I'm creating two bodies. The first body is created using BodyFactory.CreateCircle and BodyType.Dynamic. This body can be moved around using the keyboard (which sets Body.LinearVelocity). The second body is created using BodyFactory.CreateRectangle and BodyType.Static. This body is static and never moves. Then I'm using this code to calculate the force of collision when the two bodies collide: staticBody.FixtureList[0].AfterCollision += new AfterCollisionEventHandler(AfterCollision); protected void AfterCollision(Fixture fixtureA, Fixture fixtureB, Contact contact) { float maxImpulse = 0f; for (int i = 0; i < contact.Manifold.PointCount; i++) maxImpulse = Math.Max(maxImpulse, contact.Manifold.Points[i].NormalImpulse); // maxImpulse should contain the force of the collision } This code works great if both of these bodies are set to IgnoreCCD=true. I can calculate the force of collision between them 100% reliably. Perfect. But here's the problem: If I set the bodies to IgnoreCCD=false, that code becomes wildly unpredictable. AfterCollision is called reliably, but for some reason the NormalImpulse is 0 about 75% of the time, so only about one in four collisions is registered. Worse still, the NormalImpulse seems to be zero for completely random reasons. The dynamic body can collide with the static body 10 times in a row in virtually exactly the same way, and only 2 or 3 of the hits will register with a NormalImpulse greater than zero. Setting IgnoreCCD=true on both bodies instantly solves the problem, but then I lose continuous physics detection. Why is this happening and how can I fix it? Here's a link to a simple XNA 4 solution that demonstrates this problem in action: http://www.mediafire.com/?a1w242q9sna54j4

  • Activate Your Monitor via Motion Trigger

    - by ETC
    Most people are in the habit of jiggling their mouse or tapping their keyboard when they want to wake their monitor. This clever electronics hack adds a sensor to your computer for motion-based monitor activation. At the DIY and electronics blog Radio Etcetera they tackled an interesting project and shared the build guide. Their local volunteer fire department needed a monitor on for quick information checks but they didn’t need it on all the time and they didn’t want to have to walk over and activate the monitor when they needed it. The solution involved hacking a simple infrared security sensor and wiring it via USB to send a mouse command when motion is detected in the room. Fire fighter walks in, monitor turns on and displays information; fire fighter leaves and the monitor goes back to sleep.

  • Ubuntu...I love you, I hate you

    - by gregarobinson
     I have been working on seeing if a .NET 3.5 application will port over to Linux, Ubuntu to be specific. I started with version 9.01, then 9.10 and now 10.04 as I find more and more that I need from Mono. I have a dual boot on a dev box, Windows 7 and Ubuntu. An upgrade from Ubuntu 9.01 to 9.10 caused my mouse and keyboard to lock up. I was able to boot from a 9.10 cd. Then, I upgraded to 10.04 as I needed Mono 2,2. Upgrade worked, lost my windows boot though. it seems grub somehow jumped in and messed up the windows boot. After Googlign liek crazy and trying this and that, these 2 links finally got me my windows boot back:http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Boot_Sector http://support.microsoft.com/kb/927392So, I am now thinking about trying SuSe instead as I hear\read it's more stable. I think a lot of my pains have been related to learning and getting use to Linux.

  • What feature is at play when Ctrl+Shift+Alt+U,E "types" an unprintable hex 000E?

    - by Peter.O
    I tend to use Ctrl+Shift+Alt for my customized system-wide keybindings. When I tried Ctrl+Shift+Alt+U it printed an underscored u and waited for more keyboard input!... Some keys were accepted and some were not... eg. Numbers were accepted and they too were underlined, but only a few keys allowed me to break out. I then tried Ctrl+Shift+Alt+U immediately followed by Ctrl+Shift+Alt+E. This produced an unprintable hex 000E(?) and broke out of the loop... The unprintable character got me thinking that this may be Unicode related. If so, how so? What is happening here? Is this underscored u a trigger for an Input Method Editor? This behaviour occurs: Here (as I type), "gedit", text-edit fields... (but not in the Terminal)... and "gvim" reported "pattern not found"...

  • 2D/Isometric map algorithm

    - by Icarus Cocksson
    First of all, I don't have much experience on game development but I do have experience on development. I do know how to make a map, but I don't know if my solution is a normal or a hacky solution. I don't want to waste my time coding things, and realise they're utterly crap and lose my motivation. Let's imagine the following map. (2D - top view - A square) X: 0 to 500 Y: 0 to 500 My character currently stands at X:250,Y:400, somewhere near center of 100px above bottom and I can control him with my keyboard buttons. LEFT button does X--, UP button does Y-- etc. This one is kid's play. I'm asking this because I know there are some engines that automate this task. For example, games like Diablo 3 uses an engine. You can pretty much drag drop a rock to map, and it is automatically being placed here - making player unable to pass through/detect the collision. But what the engine exactly does in the background? Generates a map like mine, places a rock at the center, and checks it like: unmovableObjects = array('50,50'); //we placed a rock at 50,50 location if(Map.hasUnmovableObject(CurrentPlayerX, CurrentPlayerY)) { //unable to move } else { //able to move } My question is: Is this how 2D/Isometric maps are being generated or there is a different and more complex logic behind them?

  • Presenting the Cloud in a Different Way

    - by BuckWoody
    I had the honor of presenting the Developers at the Portland PASS chapter, and decided to go a different way than just using PowerPoint Slides…. (click on any picture to enlarge) The point is that when you need to get a point across, it’s OK to change tactics to make sure the information sticks. In this case, I decided to make the audience the PowerPoint. I used a few props to show the various paradigms we use to describe what the industry uses for the word “cloud” First, we talked about Infrastructure as a Service. I picked a gentleman who didn’t quite fit the hard hat and safety vest I picked out for him. Notice our “user” as she accesses our “Server” (complete with tray and glass) which has been virtualized.    Software as a service comes next. In this case, the user and potentially even customers just access software (represented here as a Windows ME box…) remotely – everything is virtualized. Finally, Platform as a Service – Yup, Platform shoes as a necklace, and a tie-dye shirt to represent the 70’s – a decade when mainframes used stateless programming as well. Notice also the components of Windows Azure – Compute (Keyboard) Application Fabric (Toy Bus) and Storage (Bucket).   And at the end of the day, it’s all about serving those customers…

  • An unexpected pleasure from Windows 8

    - by eddraper
    This post is certainly on the more nuanced side of all the goodness that is Windows 8, but it’s about something that’s really changed my PC usage experience for the better. Besides being a geek and the enjoying all the techno-thrills and chills that go along with sitting in front of a keyboard all day, I really love the forest.  Trees have always been special to me.  The feeling of being in the forest with all the sounds and ambiance, the broken light, the fragrance of the air… it’s paradise to me. As I can’t get there often, due to work, and quite often the heat here in Texas, I’ve found something that can at least partially fill the gap…  When you install Windows 8, you’ll have an app called “Naturespace” from http://www.naturespace.com/ .  It boasts a number of predefined loops in what they call “holographic audio.”  They’re essentially high-tech 3D sound fields recorded in natural environments. After checking them out, I really liked the sound of the “Daybreak” selection: A great benefit is that you don’t have to be in Metro/Modern/Windows App Store mode, in order to keep the sound playing.  To start the day, I click on Daybreak, start it, then go back to the desktop and fire up VS, Chrome, etc. As I work and play, I’m surrounded by this delightful background ambiance which relaxes me and puts my mind at ease. Give it a try.  I think you’ll like it.  And no, you don’t need ear buds or headphones to get the benefit.

  • Installer gets stuck with a grayed out forward button.

    - by TRiG
    I have a CD with Ubuntu 10.10 and a laptop with Ubuntu 8.10. The laptop had all sorts of crud on it, and anything I wanted to keep was backed up on an external drive, so I was happy to do a wipe and reinstall instead of an update. So after a bit of faffing about trying to work out how to get the thing to boot from the CD drive, I did that. So the screen comes up with the choice: the options are Try Ubuntu and Install Ubuntu. I choose to install and to overwrite my current installation. So far so good. I then get a progress bar labelled something like copying files (I forget the exact wording) and further options to fill in for my location, keyboard locale, username and password. On each of these screens there are forward and back buttons. On the last screen (password), the forward button is greyed out. Well, I think to myself, no doubt it will become active when that copying files progress bar completes. The progress bar never completes. It hangs. And the label changes from copying files to the chirpy ready when you are. The forward button remains greyed out. The back button is as unhelpful as you'd expect it to be. And there's nothing else to click. We have reached an impasse. I tried restarting the laptop, to test whether it actually was properly installed. It wasn't. I tried to run Ubuntu live from the CD, to test whether the disk was damaged. That wouldn't work either, but I suspect it's just because the laptop is old and has a slow disk drive. I'm typing this question on another computer using the Ubuntu live CD and it's working fine. So there's nothing wrong with the CD.

  • How do I install Ubuntu 12.04 PPC on a PowerPC G4 from commands line or fix the graphical mode?

    - by Gerardo Rodríguez
    Good afternoon. I'm new to this Linux world so I hope someone can help me . I recently got a Mac as a gift, a PowerPC G4 , which has 1GB of RAM but came with no optical drive or hard drive. So I put a dvd burner and a hard drive of 40 GB I got. Then download an iso of Ubuntu 12.04 for PowerPC and burned onto a CD. I'm trying to install from Open Firmware ( as I haven't a Mac keyboard, I use one standard ) . Finally, the Installation CD boots , but on live mode and after the Ubuntu 12.04 screen I get a message that there is a problem with my graphics adapter but I can continue with minimal graphics and give me the command line . My question is that how do I install through a text or if there is any way to fix this problem to run the graphical mode and so can continue the installation of Ubuntu, and if once installed Ubuntu the problem will be fixed or what? I would appreciate if you help me , as I mentioned before, there is almost nothing of Ubuntu but I think it will be easier than trying to get the Mac OS X proper . Spend good.

  • PowerBroker (Likewise-Open) + Ubuntu 13.04 -> 13.10 Upgrade

    - by JoBu1324
    I just upgraded Ubuntu from 13.04 to 13.10, and now I can't log into Active Directory; my system is integrated using PowerBroker Identity Services (PBIS), which used to be called Likewise-Open. So far I have identified the following symptoms: I am able to log in with my credentials via ssh. The screen goes black when attempting log into my account via the login screen. I've tried leaving the domain, purging PBIS, and re-installing the latest version of PBIS. I've been trying the troubleshooting section I found here, but I haven't had any success.

  • Desktop switcher appears to be broken for quick double-switches

    - by Jon Blackburn
    I'm wondering if anyone else has seen this. I have three virtual desktops aligned in a horizontal row. In the middle desktop I have only a single application window. I have keyboard shortcuts mapping to navigate between the desktops. Obviously, I never use the up/down arrows because I only have one row of workspaces. Here's the problem, which only started to happen after I installed 12.04.1: When I rapidly hit to go from workspace 1 to workspace 3, the window on workspace 2 gets moved to workspace 1. I have checked using both Unity and Gnome3, and the behavior is the same under both. If I change back to the default workspace setup (a 2x2 grid of desktops) things seem to settle down (i.e., no wandering windows). Not every type of application window behaves the same way. I couldn't get a Chrome browser to jump from 2 to 1, but both Terminal and Terminator exhibit the behavior. Any thoughts? Better workarounds? Thanks in advance.
