  • Can't boot ubuntu 12.04, stuck in busybox. Can't view files from ubuntu trial disc, or windows partition

    - by Maura
    So, I'm slightly computer literate, and find myself frustrated and overwhelmed. My computer is a acer laptop, extensa 5620-6572. I have a dual boot with windows vista and ubuntu 12.04. The ubuntu 12.04 I got was from an upgrade, not a disc. I tried to load ubuntu 12.04, and it gets stuck in the "busybox", and I don't know how to proceed from there. I went to my windows partition and downloaded Ex2 from http://sourceforge.net/projects/ext2fsd/ and thought I'd try access my files and save them to a external HD. Then when I restarted my computer and went to windows, it always freezes after it loads the OS. So then, I downloaded and burned a ubuntu 12.04 boot disk, and the disk works fine. But I still can't figure out how to view files on my harddrive.

  • how to focus the desktop on unity

    - by user25119
    I'm using Ubuntu 11.10 (unity 4.24.0) and I can't seem to focus the desktop. For example, if I press Mod4+D, the window I had opened stays focused, but the image is see is my wallpaper. If I minimize all windows one by one, the last window I minimize is still focused when the desktop finally appears. This means I can't add desktop icons, nor use the mouse in it. I thought about reporting a bug, but everything works fine on other computers with the latest version of Ubuntu I've used, so I'm wondering about what's happening. Before, when I pressed Mod4+D, the Unity Top Menu would say "Desktop - File Edit ..." and I could use the desktop properly. Thanks in advance!

  • Moving two objects proportionally

    - by SSL
    I'm trying to move two objects away from each other at a proportional distance, but on different scales. I'm not quite sure how to do this. Object A can go from position 0.1 to 1. Object B has no limits. If object B is decreasing, then Object A should be decreasing at rate R. Likewise, if Object B is increasing, then Object A increases at rate R. How can I tie these two Object positions together so that in an update loop, they automatically update their positions? I tried using: ObjA.Pos += 0.001f * ObjB.VelocityY; //0.001f is the rate This works but there's an error each time it runs. ObjA starts off at its max position 1 but then the next time it will stop at 0.97, 0.94, 0.91 etc.. This is due to the 0.001f rate I put in. Is there a way to control the rate, yet not end up with the rounding error?

  • Can't interact with windows after first login

    - by evilpie
    Every time I restart my computer and login into my ubuntu account for the first time, I can't click on anything besides the bar on the left. So I can start Firefox from there, but I am not able to click on the new tab button etc. Same will all other apps. I can start the Terminal via the keyboard, but I can't move it around. So I have to logout via the keyboard and login again. Usually everything works fine now. Just waiting doesn't help. The only obvious change I made to Ubuntu was to move the /home directory.

  • Checking a record is due based on the 'occuring' field

    - by andy
    I have records that have dates against them and an occurring field that contains none,yearly and monthly id status note date last_updated occurring 1 open --- 01/01/2011 01/02/2010 yearly 2 open --- 05/05/2011 03/05/2011 monthly 3 open --- 06/06/2011 05/06/2011 none Now I need to be able to check if a record is due (the date set has passed) which works perfect if occurring is set to none but I'm unsure of how to approach it when it's set to yearly or monthly (IE: This day in the year/month has passed) So with the above records, if I had a method on the record called due? providing the status is 'open' it needs to return true every year when it's passed that date if it's not been updated within the year yet. I apologise if this is confusing but it's melting my brain just trying to think of it, let alone put it into words.

  • C++ unmanaged inside winform

    - by Gosso
    First: I am using C# and C++ on windows 7. I have created a basic rendering engine in c++ with directx 10. It works good as a stand alone application. But, when I sending the Form.Handle of a WinForm I want to render inside to the engine it crashes during D3D10CreateDeviceAndSwapChain with the following error: HRESULT: 0x887a0001 (2289696769) Name: DXGI_ERROR_INVALID_CALL I get the handle from the winform during loading of the form. unsafe { void *ptr=m_view.Handle.ToPointer(); uint v = (uint)ptr; lhandle = v.ToString(); };

  • using per pixel collision for an elastic response

    - by Codejoy
    I realize this might be open ended ended but curious if I just did some over kill... I had this http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and i reworked it to work with my animation code in XNA and what not. It works well, but now I want to use this to decide if there was a collision and to have the items (characters) bounce off eachother elastically. Was the per pixel too much and I could of just used a bounding box ? (in fact would that of been preferred for what needs to be calculated in the response for an elastic collision?) Looking for guidance really.

  • Rendering trillions of "atoms" instead of polygons?

    - by Baring
    I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

  • How do I turn off WLAN automatically when LAN is connected?

    - by derroman
    I use my Thinkpad laptop with a docking station. The docking station is connected to my router via LAN. When I walk around the house I use my laptop with WLAN. Is it possible (and how) to manage these devices with a script or something to work like this: If a LAN-Connection is up, the OS should turn off Wifi and if LAN-Connection gets lost (undocking) Wifi should turn on automatically. I use Ubuntu 11.04 64bit with Gnome 2. The system works on an Lenovo ThinkPad R500 with. WLAN-Device: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] LAN-Device: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02) Any help would be appreciated. Thanks.

  • Google Analytics Request URI to Event advanced filter

    - by confidentjohn
    I have a query string attached to a Request URI. Whilst I can see this data within the pages report and it works, I was thinking about setting up an advanced filter to convert the request URI to an Event, with the hope this would clean up my pages report and sit this query with related events in my data. I can see in advanced filters that this is possible, but seems limited to specifying a single event area, so Cat, action or Label, not all 3. Does any one know how I could set up an advanced filter to find any URIs that contain a specific query string, say example below. www.example.com?querystring=123 and convert this into an event, where I can set the Cat, action and label.

  • Introduction to Agile Development

    - by Grant Fritchey
    Even though my current job is a little weird, I still consider myself to be a DBA. I didn’t start that way in IT. I came through support and into development. I loved development. There was a constant struggle to attempt to improve your code, your understanding, and, most importantly, the process of development itself. Development can be slow and tedious. Left alone, developers can simply disappear to build a project and not come back for two years, at which time they deliver it. But, maybe that software isn’t what you wanted, or it’s no longer needed, or who knows what. So developers are constantly attempting to improve their processes in order to deliver more relavent software quicker (something DBAs could learn about). I really admire it. One of the many processes that has come out of that constant striving is known as Agile. As the name implies, Agile development attempts to come up with a quick, fast turning, business aware, well, for want of a word, agile, process that is more responsive to the needs of the business. There are tons and tons of books and blogs and videos on the subject that can get you going. But, Agile isn’t easy (note, Easy is not part of the name). Agile processes can be hard. I’ve worked on multiple agile teams, some successful, some not. The two principal differences between the teams were their discipline and their knowledge of the process. Discipline, that comes from within. But knowledge, ah, well there I can help. Red Gate is bringing a series of free instructional events to the United States in a few weeks time focused primarily on SQL Server (click here right now to register while there’s still space). We’re also offering some .NET instruction too. That’s a full day, free, with top experts in the business. But, the next day, there’s a full day session introducing Agile. You can go to this and learn how to do Agile. Develop that knowledge that will enable you to successfully use the Agile process. Go to this web site to check it out. No, this event is not free, but not everything can be. And it’s not just for developers. DBAs, you need to learn this stuff too. Management could also benefit from understanding these processes (because you guys can help to enforce discipline). It’s really for everyone involved in the development process.

  • Keeping application backend and UI synchronised

    - by Deanna
    Hi all. I have an app that works with a list of objects so has one central keyed list. The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading. Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit. I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way. I can also do it lazily and repopulate the tree each time or periodically (very hackish). Does anyone have any better thoughts on how to structure this? This is being done in C# 2.0 but the concepts apply to any environment. Thanks

  • Machine check error on ASUS while booting from USB

    - by user100453
    I put the last Ubuntu iso on my USB stick using UNetBootin, after formatting it to fat32. I've already done that before with other operating systems and it worked. I can't actually boot Ubuntu from USB since I get a black screen with the error "Machine check error" on top the an automatic reboot happens. The error appears right after the boot, I can't see anything else before. I'm using my ASUS X54L latop. Does anybody know how to solve this? Installation from CD/DVD works.

  • unable to start regionservers in HBase

    - by amsal
    I have a problem starting regionservers on slave PCs. When I enlist only master PC in conf/regionservers everything works fine but when I add two more slaves to it the hbase does not start. If I delete all hbase folders in the tmp folder from all PCs and then start regionserver (with 3 regionservers enlisted) the hbase gets started but when I try to create a table it again fails (gets stuck). I am using hadoop 0.20.0 which is working fine and hbase 0.92.0. I have 3 PCs in cluster, one master and two slaves. Also tell that is DNS (both forward and backward lookup working) necessary for hbase in my case? Is there any way to replicate hbase table to all region servers? I.e. I want to have a copy of table at each PC and want to access them locally (when I execute map task they should use their local copy of hbase table).

  • "Collection Wrapper" pattern - is this common?

    - by Prog
    A different question of mine had to do with encapsulating member data structures inside classes. In order to understand this question better please read that question and look at the approach discussed. One of the guys who answered that question said that the approach is good, but if I understood him correctly - he said that there should be a class existing just for the purpose of wrapping the collection, instead of an ordinary class offering a number of public methods just to access the member collection. For example, instead of this: class SomeClass{ // downright exposing the concrete collection. Things[] someCollection; // other stuff omitted Thing[] getCollection(){return someCollection;} } Or this: class SomeClass{ // encapsulating the collection, but inflating the class' public interface. Thing[] someCollection; // class functionality omitted. public Thing getThing(int index){ return someCollection[index]; } public int getSize(){ return someCollection.length; } public void setThing(int index, Thing thing){ someCollection[index] = thing; } public void removeThing(int index){ someCollection[index] = null; } } We'll have this: // encapsulating the collection - in a different class, dedicated to this. class SomeClass{ CollectionWrapper someCollection; CollectionWrapper getCollection(){return someCollection;} } class CollectionWrapper{ Thing[] someCollection; public Thing getThing(int index){ return someCollection[index]; } public int getSize(){ return someCollection.length; } public void setThing(int index, Thing thing){ someCollection[index] = thing; } public void removeThing(int index){ someCollection[index] = null; } } This way, the inner data structure in SomeClass can change without affecting client code, and without forcing SomeClass to offer a lot of public methods just to access the inner collection. CollectionWrapper does this instead. E.g. if the collection changes from an array to a List, the internal implementation of CollectionWrapper changes, but client code stays the same. Also, the CollectionWrapper can hide certain things from the client code - from example, it can disallow mutation to the collection by not having the methods setThing and removeThing. This approach to decoupling client code from the concrete data structure seems IMHO pretty good. Is this approach common? What are it's downfalls? Is this used in practice?

  • Silverlight 3.0 and ADO.NET data service framework(An error occurred while processing this request)

    - by ybbest
    Today , I try to write a Silverlight app that talks to SharePoint 2010 using the REST API.However after deploy the silverlight app and run the code , I got the following error.In order to fix this I need to make the target framework of your caller application to 4.0,in this case I need to use Silverlight 4.0 instead 3.0.After I have done that and redeploy the solution to the SharePoint.It works like a charm.   Exceptions details: System.Data.Services.Client.DataServiceQueryException: An error occurred while processing this request. Request version ’1.0′ is too low for the response. The lowest supported version is ’2.0′. However , if you got the error like this: Could not load type ‘System.Data.Services.Providers.IDataServiceUpdateProvider’ from assembly ‘System.Data.Services, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′,then you need to install ADO.NET Data Services Update for .NET Framework 3.5 SP1 ,you can download here (for windowns 7 and server 2008 r2 ) or here (for windows vista of server 2008).

  • programming can be taken as specialization - but what will I do still unclear [closed]

    - by C4CodeE4Exe
    I am bit confusing about my goals although whole motivation thing is $$$ but still there is something pushing me to pursue higher studies(being frustrated from boot-licking attitudes of peers and lottery system here in India for promotions,pay hikes and onshore opportunities). I am afraid I do not have any goals.I am software developer mainly in JAVA, but an ECE graduate.I want to work in programming languages. My problem is that I am not even Jack of all trades.I have experience in programming and thats where I am good(self-pro-claimed or atleast people say this treating them as a critics). I have decided to go with the wind and applying for programming languages as my specialization.But I know how to code,write test cases,how Perosnal and commercial IT insurances solution works.What I do not know is how to show that what I will do during my masters.I have no idea about what to showcase, how would my work ex will help me. totally oblivious thoughts... thanks waiting for replies....

  • What exactly is a chroot? Is it similar to a simultaneous dual boot?

    - by mathematician1975
    It has been suggested to me that the use of a chroot might solve my problem of building an application that must run on an embedded device. I have inferred from this description that it is somehow similar to creating the embedded environment locally on my machine which I can then use to develop on from my desktop development machine. Is this the right way to look at the functionality or have I totally misunderstood? In order to get some idea of how it works I read this https://wiki.ubuntu.com/DebootstrapChroot which I will attempt to make a chroot for an old Ubuntu version on my machine. However, as I am a total linux novice, I am a bit concerned that as I do not entirely know what I am doing is there anyway that I could end up with an unusable system?? Is this something that a novice should even attempt???

  • How do I prevent the Sleep button from locking the screen

    - by elmicha
    My keyboard has a Sleep button. I defined a shortcut in System Settings, Keyboard Shortcuts own settings (or similar), so that the Sleep buttons runs a script. That works. But since my upgrade to Oneiric, something also locks the screen (in the same way the screen is locked when I press Ctrl+Alt+L). Can I disable that behaviour? What's the name of that lock screen? I tried hiding gnome-screensaver and /etc/acpi/ and I looked in gconf-editor /apps/gnome-power-manager/buttons. I didn't find anything related in dconf-editor.

  • Delete all traces of windows from Ubuntu

    - by TheOm3ga
    I used to have a dual boot in one of my hard disk drives - Ubuntu and Windows 7. Then, I added a SSD which is now my main hard disk drive, and I'm using it for Windows 7 completely, keeping Ubuntu in the old HD. I restored the Grub so everything works ok, except for one thing. Everytime I update the grub, it detects two windows: Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 Obviously, I don't want it to detect the Windows on sdb1. Because I no longer use it (I manually deleted the files). What can I do about that without wiping out completely the partition?

  • Is there a prohibition against scaling collision shapes at runtime?

    - by Almo
    So, I have a StaticMeshComponent attached to an Actor: Begin Object Class=StaticMeshComponent Name=StaticMeshComponentObject StaticMesh=StaticMesh'QF_Art_Powers.Mesh.GP_ForcePush' CollideActors=true BlockActors=false //Scale3D=(X=5, Y=1.5, Z=3) // ALMODEBUG End Object CollisionComponent=StaticMeshComponentObject Components.Add(StaticMeshComponentObject) Ordinarily, the actor gets spawned, anything touching it gets bumped, and the actor despawns itself. If I set the Scale3D as a default property, everything works as I expect. But I want to scale it at runtime, like this: function SetImpulseComponentTemplate(QuadForceBoxImpulseComponent Value) { Local Vector ScaleVec; ScaleVec.X = Value.Length; ScaleVec.Y = Value.Width; ScaleVec.Z = Value.Height; CollisionComponent.SetScale3D(ScaleVec); } When I do this, the thing only collides as if it were not scaled. If I leave the actor spawned so I can see it, it is scaled. If I also "show collision", the collision displays correctly as well. Is there a prohibition against scaling collision shapes at runtime?

    I have a VM I am trying to run under Hyper-V on Windows 8 Pro. I am using an Asus PDE-N15 adapter on the host machine. When I run Windows 8 in the VM it connects to the network and everything works. When I use Linux (Ubuntu 13.04 32-bit, Ubuntu 13.04 64-bit, Fedora, CentOS) it will not connect to the network. When I run ifconfig I see the adapter show up as eth0 with the correct HWaddr. I see that TX bytes 0, and RX bytes == 0. Could anyone help me figure out how to get this to work?
