• Swap partition not recognized (The disk drive with UUID=... is not ready yet or not present)

  - by ladaghini

  I think I had an encrypted swap partition, because I chose to encrypt my home directory during the installation. I believe that's what the line with /dev/mapper/cryptswap1 ... in my /etc/fstab is all about. I did something to bork my swap because on the next boot, I got a message (paraphrased): The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present. Wait to continue. Press S to skip or M to manually recover. (As a side note, pressing S or M seemed to do nothing different from just waiting.) Here's what I've tried: This tutorial on how to fix the swap partition not mounting. However, in the above, the mkswap command fails because the device is busy. So I booted from a live USB, ran GParted to reformat the swap partition (which showed up as an unknown fs type), and chrooted into the broken system to try that tutorial again. I also adjusted /etc/initramfs-tools/conf.d/resume and /etc/fstab to reflect the new UUID generated from formatting the partition as a swap. That still didn't work; instead of /dev/mapper/cryptswap1 not present, "The disk drive with UUID=[swap partition's UUID] is not ready yet or not present..." So I decided to start afresh as though I never had created a swap partition in the first place. From the Live USB, I deleted the swap partition altogether (which, again showed up in GParted as an unknown fs type), removed the swap and cryptswap entries in /etc/fstab as well as removed /etc/initramfs-tools/conf.d/resume and /etc/crypttab. At this point the main system shouldn't be considered broken because there is no swap partition and no instructions to mount one, right? I didn't get any errors during startup. I followed the same instructions to create and encrypt the swap partition, starting with creating a partition for the swap, though I think fdisk said a reboot was necessary to see changes. I was confident the 3rd process above would work, but the problem yet persists. Some relevant info (/dev/sda8 is the swap partition): /etc/fstab file: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

• Can an expert examine my .NET MVC 4 application? [on hold]

  - by Till Death Developer

  Problem Definition: I need an expert to examine my application not for errors but have a look at how my implementation goes and tell me whether am doing a good job or am just creating a huge mess, and please me with suggestion on how i should improve my work? Points of Concern: Neat Solution(Can find the thing you are looking for easily). Low Redundancy. Efficiency (Load time, Speed, etc...) Data Access Implementation. Authentication System Implementation. Data Services Implementation. Note: Application is just a playground for testing new implementation approaches so it may seem meaningless because it is, however not the subject any way i just need to know if am doing things in a good way(Nothing is the right way but there is good and bad).

• Ubuntu does not work with Nvidia drivers, gives random squares after logging in

  - by jimbo

  I tried installing both with wubi and by booting from a usb drive. After I tried both it was the same. Ubuntu tried to login, but after a while, a weird pattern with squarely shapes appeared. At one point, after using recovery mode and then the low graphics one (i don't remember how it was called exactly) i managed to get in. It still didn't display at correct resolution, and the mouse was invisible at times. However, after rebooting once, because i tried downloading the nvidia drivers, i didn't manage to get in again, so i have the same problem... I have no idea what to try to become unstuck. The main problem is that after the login, ubuntu crashes, with a screen full of randomly coloured squares. Should I just give up?

• Alt+F2 (Run Application) doesn't work for custom commands

  - by Felix

  In order to speed up Android development, I've edited my ~/.bashrc to add some paths to PATH: export PATH=${PATH}:/opt/android-sdk/tools:/opt/android-sdk/platform-tools This works just fine from the command line (I can just type android and, no matter where I am, the Android SDK and AVD Manager will start up just fine. However, if I try to type android in the Alt+F2 dialog (Run Application), it gives the following error: Could not open location 'file:///home/felix/android' Error stating file '/home/felix/android': No such file or directory Why is that? What PATH does the Run Application dialog use?

• Unable to Install GRUB in /dev/sda on raid drives

  - by Henry

  I'm trying to install 12.04LTS on a server but keep running into the unable to install grub error like so "Unable to Install GRUB in /dev/sda". The drives are in raid1 and I'm using fakeraid on a supermicro motherboard, which according to the manual is fully supported. I've tried installing both from USB and CD-R but still no luck. I'm not dual booting with any other OS, just using 2x320gb drives and have been choosing to install using the entire disk. Any ideas what I'm doing wrong or can do to fix this? Thanks

• Slow internet browsing in Ubuntu

  - by Mark

  I have a dual boot set up with windows and ubuntu, when I'm using windows internet browsing is a lot faster than when I'm using ubuntu and I don't know why. It's like there's just a big latency rather than the maximum speed is lower, there's a big delay before anything happens when using Ubuntu, it happens with all websites all the time. I've never configured the internet connection because it just worked straight away. I have broadband connection through a router shared with some other computers, when we set up the router and internet connection everything was done with windows. Any ideas on what I could do to fix this? Thanks to anyone who replies.

• Power management issues on an Asus N55

  - by Andrea Borga

  I noticed that with respect to Win7 on my Asus N55 Ubuntu 12.04 tend to overheat the system. After startup the fan controller takes control of the fan, I could here it slowing down, after a few second following a login the fan increases its speed again. Though there are no processor hungry process: top shows only Xorg consuming 4%. Even with the system monitor the CPUs load look ok. Is it a power management related problem? This can cause battery life troubles in general, and electronics is never happy to be overheated. Is there a better tool to root the cause of the issue?

• Platformer Starter Kit - Collision Issues

  - by Cyral

  I'm having trouble with my game that is based off the XNA Platformer starter kit. My game uses smaller tiles (16x16) then the original (32x40) which I'm thinking may be having an effect on collision (Being it needs to be more precise). Standing on the edge of a tile and jumping causes the player to move off the the tile when he lands. And 80% of the time, when the player lands, he goes flying though SOLID tiles in a diagonal fashion. This is very annoying as it is almost impossible to test other features, when spawning and jumping will result in the player landing in another part of the level or falling off the edge completely. The code is as follows: /// <summary> /// Updates the player's velocity and position based on input, gravity, etc. /// </summary> public void ApplyPhysics(GameTime gameTime) { float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; Vector2 previousPosition = Position; // Base velocity is a combination of horizontal movement control and // acceleration downward due to gravity. velocity.X += movement * MoveAcceleration * elapsed; velocity.Y = MathHelper.Clamp(velocity.Y + GravityAcceleration * elapsed, -MaxFallSpeed, MaxFallSpeed); velocity.Y = DoJump(velocity.Y, gameTime); // Apply pseudo-drag horizontally. if (IsOnGround) velocity.X *= GroundDragFactor; else velocity.X *= AirDragFactor; // Prevent the player from running faster than his top speed. velocity.X = MathHelper.Clamp(velocity.X, -MaxMoveSpeed, MaxMoveSpeed); // Apply velocity. Position += velocity * elapsed; Position = new Vector2((float)Math.Round(Position.X), (float)Math.Round(Position.Y)); // If the player is now colliding with the level, separate them. HandleCollisions(); // If the collision stopped us from moving, reset the velocity to zero. if (Position.X == previousPosition.X) velocity.X = 0; if (Position.Y == previousPosition.Y) velocity.Y = 0; } /// <summary> /// Detects and resolves all collisions between the player and his neighboring /// tiles. When a collision is detected, the player is pushed away along one /// axis to prevent overlapping. There is some special logic for the Y axis to /// handle platforms which behave differently depending on direction of movement. /// </summary> private void HandleCollisions() { // Get the player's bounding rectangle and find neighboring tiles. Rectangle bounds = BoundingRectangle; int leftTile = (int)Math.Floor((float)bounds.Left / Tile.Width); int rightTile = (int)Math.Ceiling(((float)bounds.Right / Tile.Width)) - 1; int topTile = (int)Math.Floor((float)bounds.Top / Tile.Height); int bottomTile = (int)Math.Ceiling(((float)bounds.Bottom / Tile.Height)) - 1; // Reset flag to search for ground collision. isOnGround = false; // For each potentially colliding tile, for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { // If this tile is collidable, ItemCollision collision = Level.GetCollision(x, y); if (collision != ItemCollision.Passable) { // Determine collision depth (with direction) and magnitude. Rectangle tileBounds = Level.GetBounds(x, y); Vector2 depth = RectangleExtensions.GetIntersectionDepth(bounds, tileBounds); if (depth != Vector2.Zero) { float absDepthX = Math.Abs(depth.X); float absDepthY = Math.Abs(depth.Y); // Resolve the collision along the shallow axis. if (absDepthY < absDepthX || collision == ItemCollision.Platform) { // If we crossed the top of a tile, we are on the ground. if (previousBottom <= tileBounds.Top) isOnGround = true; // Ignore platforms, unless we are on the ground. if (collision == ItemCollision.Impassable || IsOnGround) { // Resolve the collision along the Y axis. Position = new Vector2(Position.X, Position.Y + depth.Y); // Perform further collisions with the new bounds. bounds = BoundingRectangle; } } else if (collision == ItemCollision.Impassable) // Ignore platforms. { // Resolve the collision along the X axis. Position = new Vector2(Position.X + depth.X, Position.Y); // Perform further collisions with the new bounds. bounds = BoundingRectangle; } } } } } // Save the new bounds bottom. previousBottom = bounds.Bottom; } It also tends to jitter a little bit sometimes, I'm solved some of this with some fixes I found here on stackexchange, But Ive only seen one other case of the flying though blocks problem. This question seems to have a similar problem in the video, but mine is more crazy. Again this is a very annoying bug! Any help would be greatly appreciated! EDIT: Speed stuff // Constants for controling horizontal movement private const float MoveAcceleration = 13000.0f; private const float MaxMoveSpeed = 1750.0f; private const float GroundDragFactor = 0.48f; private const float AirDragFactor = 0.58f; // Constants for controlling vertical movement private const float MaxJumpTime = 0.35f; private const float JumpLaunchVelocity = -3500.0f; private const float GravityAcceleration = 3400.0f; private const float MaxFallSpeed = 550.0f; private const float JumpControlPower = 0.14f;

• Recover files from NTFS drive with bad sectors

  - by Martin

  A few nights ago I have created a backup of my data on an external 500 GB NTFS USB hard drive. I have then formatted my computer, reinstalled Ubuntu and started transferring back the data from the external HDD. Unfortunately some files have became corrupted and Ubuntu is unable to copy them over. The same issue happens if I login using Windows 7. Disk Utility detects with SMART that there are "a few bad sectors". Some of files are perfectly intact, but other files cannot be accessed (nor read, copied...) although they are displayed within nautilus and show the correct file size. Is there anything I can do to recover this data? I have thought of using TestDisk but this utility seems more useful for repairing lost partitions or deleted files. I have also thought of using ddrescue so I could at least have a low level copy of the disk but I am not sure what use to make of it in order to recover the data!!!

• updater stuck on downloading python files

  - by Tim

  However i am a java programmer is consider myself as a linux noob. So i could use a little help here... I am trying to update my ubuntu from version 10.04 to 12.04.1 (LTS). The downloading start and runs at around 10MB/s untill i am somewhere near 26% and the speed just drops to 0. I figured i could use the command "do-release-update" so i could see what it was doing. Again the same occured: the downloading stucked on 26% at "http://nl.archive.ubuntu.com/ubunutu/ precise/main python-qt4 1386 4.9.1-2ubuntu1". It says it downloaded 41% of that file/package. It also tries another wget on the same file every X seconds. Help? Greetings Tim, Holland.

• Used DBAN to wipe Lenovo u410 then installed Ubuntu. Need to install windows 8, but I get an error.

  - by David

  When I try to boot from my windows 8 USB (tested on a separate PC), I get this error text "The boot configuration data for your pc is missing or contains errors." I want to install windows again so I can fix a battery issue I'm having. Lenovo's power management app has an option to keep the battery at 60% if the laptop stays plugged in most of the time. I enabled this, then formatted without changing it back. I think there might be a raid setup that I may need to remove or something. I don't mind removing Ubuntu and starting fresh. I would just love some help with all this, I'm a noob when it comes to Linux.

• Atheros 9250 wireless card keeps on disconnecting

  - by Vizi Balázs

  So I bought a Lenovo G575 laptop for learning purposes and found that the connection just simply disconnects if i'ts in use for downloading and it also does disconnect in every 2-5 minutes while browsing.I tested the card with Win7, it worked nicely.Since then I searched through all the topics connected to this card, also tried using older distros, Maverick ended up with the same results as the actual 12.04 distribution.I dont think it's the router cause i could access it from Win7.It's causing me a trouble using an external usb, cause it's taken from another PC in the house.I would be really grateful if someone could explain what should i do to fix it. Thanks in advance for the help

• How to forward an Internet connection to another network?

  - by Naveen

  Can somebody please make a shot & sweet tutorial telling how to forward an Internet connection to different network interfaces in Ubuntu...? This is the idea: I'm using a 3G usb modem to get Internet on my laptop ,which is: ppp0 IP=10.225.174.70 My Wifi device is: wlan0 MAC=78:e4:00:d4:3d:85 These devices are determined from ifconfig command. I want to share ppp0's internet connection with wlan0 device, so I can connect any other device to wlan0 and browse internet from that device. Making a Hotspot using Network settings GUI doesn't do the trick because the other device won't receive Internet, it just connects to wlan0. I heard iptables can do this, but I'm totally confused by the alien commands seen online. I'm no expert in networking. Please compose a clear & simple answer using the above devices. This is a huge annoying problem for iPhone & tablet users came to Ubuntu from Windows.

• Silverlight Cream Monday WP7 App Review # 2

  - by Dave Campbell

  Today's Review (alphabetic order): GooNews, Grocery Shopping List, Need for Speed, SurfCube, and United Nations News. I'm a day late if these are going to be 'Monday' posts, but there are lots of apps, lots of goodness, and lots of email, so I might try to do 2 a week, we'll see. So once again I've got a small review of 5 apps that are either on my phone or have been. Disclaimers at the end. In this Issue:   GooNews is a very cool app from Shawn Wildermuth (AgiliTrain). I don't know if he uses this as a demo during his instruction, but it definitely serves a purpose... wanna pick up the top news items from Google on a never-ending basis? ... this is it. You can add your own keyword searches, and send stories to InstaPaper or share via email. I like this because it brings me the news quickly and updated, and works great. GooNews is by AgiliTrain and is Free This was a request by the author, and actually surprised me. I'm a big one for lists, but I would have just done a OneNote list to SkyDrive and to my phone. This app is a lot more than that, but will take you some setup to make it be 'yours'. For obvious reasons, there are no unit prices on things, so you have to set that up to get some idea of the cost of what you're shopping for. But if you do that, you'll get a nice total. Lots of thought went into the various categories and you can add your own. There's a bit of animation on the category selection that's nice. He seems to have covered all the bases necessary to use this, even shopping 'plans' that can be saved, and emailing of lists. As I said, I'm more of a raw list person, but if you take the time to set this up, it should work very nicely for you. Grocery Shopping List is by Grocery Shopper and is $0.99 ($1.99 after Feb 1) with a free trial. This was my 2nd commercial game I bought, and the one I've played the most. I ran the trial, thought it worked great, and bought it. I've had a lot of fun with this... there's no gas pedal.. your foot is in the carbeurator from the GO!, and unless you wanna tap the screen and brake like a little girl, just hang onto the steering wheel (the phone), and guide your way through. Hours of fun and challenges here. I like this because it's got some challenge to it, and the cars seem to be very realistic in their reactions. Need for Speed Undercover is by Electronic Arts is $4.99 and has a free trial. SurfCube Browser is another app by the folks that did the GuitarTuner I reviewed on Monday. You have to see SurfCube to believe it. You've probably seen the YouTube video, if not check SilverlightCream number 1017. The app works very solid, and just as the video demonstrates. I downloaded and tried this, and it immediately did 2 things: bought it, and pinned it to my start page. I like this because it's fun to work with, and it works great as a browser. I'm about *this* close to replacing the IE tile on my front page with SurfCube. SurfCube Browser is by Kinabalu Innovation Limited and is $1.99 and has a free trial. Coming in with another News app is United Nations News by Justin Angel. This is definitely a news aggregator for 'grown ups'... news, photos, videos, and radio broadcsts from the international community all in one very slick app. This is an amazingly well thought-out and complete app. Even better yet, Justin has the code on CodePlex. A very well-done International news aggregator. United Nations News is by Justin Angel and is Free. A few disclaimers: Feel free to write me about your app and tell me about it. While it would be very cool to receive a whole bunch of xap files to review, at this point, for technical reasons, I'm unable to side-load my device. Since I plan on only doing this one day a week (twice if I find time), and only 5, I may never get caught up, so if you send me some info, be patient. Re: games ... remember I'm old... I'm from the era of Colossal Cave and Zork. Duke-Nukem 2D and Captain Comic were awesome. I don't own an XBOX or any other game system, so take game reviews from my perspective -- who knows, it may be refreshing :) I won't pay for an app or game just to try it. If you expect me to test-drive your app, it's going to have to have a Free Trial. I'm still playing with the format, comments are welcome. I decided I should alphabetize the list today... so there's no order implied Let me know what you think of the idea of doing reviews, or the layout/whatever, and Stay in the 'Light!

• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• HTG Explains: What Is Open-Source Software and Why You Should Care

  - by Chris Hoffman

  Geeks often describe programs as being “open source” or “free software.” If you’re wondering exactly what these terms mean and why they matter, read on. (No, “free software” doesn’t just mean that you can download it for free.) Whether a program is open-source or not doesn’t just matter to developers, it ultimately matters for users, too. Open-source software licenses give users freedoms they would not otherwise have.

• Hadoop and Object Reuse, Why?

  - by Andrew White

  In Hadoop, objects passed to reducers are reused. This is extremely surprising and hard to track down if you're not expecting it. Furthermore, the original tracker for this "feature" doesn't offer any evidence that this change actually improved performance (unless I missed it). It would speed up the system substantially if we reused the keys and values [...] but I think it is worth doing. This seems completely counter to this very popular answer. Is there some credence to the Hadoop developer's claim? Is there something "special" about Hadoop that would invalidate the notion of object creation being cheap?

• First of all...

  - by devboy00

  First of all, this is going to be about my long (hopefully not) and painful (most definitely) climb back into the saddle after spending all of the intervening years between .NET 1.1 and now being a PHB.  I've half-heartedly attempted to get back up to speed a couple of times, but THIS time I actually have some coding to do, AND the geeks are so amped up about all of the new technologies, I really have to do this. So...  Once again, .NET 1.1.  Right now I'm getting ready to work on a site that incorporates Fluent nHibernate, MVC, Spark, and some conventions based coding practices.  Along the way, I'll have to learn about Lambda expressions and other cool stuff that I've missed out on in the last bazillion years since I seriously coded.  Hopefully this will be a guide, or a warning for those of you who feel the need to get off the sidelines and get back into the game. Yeah, that's it for now.
