• How to Boot from iRAM Solid State Drive on Ubuntu

  - by quickshiftin

  I've got an iRAM solid state drive. I'd like to use this to store a linux root filesystem; the trouble is the device is not recognized as a hard drive to the BIOS. It only shows up if a live CD environment is loaded and the scsi drivers are available (may be other drivers needed as well). I've heard of Boot to Ram and wonder if some variation of that could work here and I could run a linux install off the iRAM??

  - by evolvd

  Laptop: HP Compaq 6710b I can boot from usb just fine with the following usb flash drives: Cruzer micro 4GB HP 4GB The flash drive that will not boot: Flash Voyager 8GB To knock out variables I did the following: Using Hard Disk Low Level Format Tool I performed a low level format Full erase with Flash Memory Tookit In windows 7 I formated the drive to fat32 Used USB-Boot-Tester to write to the drive Also used uNetbooting with various distros to see if that would make a difference My guesses on what could be preventing the drive from booting: The laptop does not support booting to usb flash drives larger than 4GB The drive is defective in some way

• Is OOP hard because it is not natural?

  - by zvrba

  One can often hear that OOP naturally corresponds to the way people think about the world. But I would strongly disagree with this statement: We (or at least I) conceptualize the world in terms of relationships between things we encounter, but the focus of OOP is designing individual classes and their hierarchies. Note that, in everyday life, relationships and actions exist mostly between objects that would have been instances of unrelated classes in OOP. Examples of such relationships are: "my screen is on top of the table"; "I (a human being) am sitting on a chair"; "a car is on the road"; "I am typing on the keyboard"; "the coffee machine boils water", "the text is shown in the terminal window." We think in terms of bivalent (sometimes trivalent, as, for example in, "I gave you flowers") verbs where the verb is the action (relation) that operates on two objects to produce some result/action. The focus is on action, and the two (or three) [grammatical] objects have equal importance. Contrast that with OOP where you first have to find one object (noun) and tell it to perform some action on another object. The way of thinking is shifted from actions/verbs operating on nouns to nouns operating on nouns -- it is as if everything is being said in passive or reflexive voice, e.g., "the text is being shown by the terminal window". Or maybe "the text draws itself on the terminal window". Not only is the focus shifted to nouns, but one of the nouns (let's call it grammatical subject) is given higher "importance" than the other (grammatical object). Thus one must decide whether one will say terminalWindow.show(someText) or someText.show(terminalWindow). But why burden people with such trivial decisions with no operational consequences when one really means show(terminalWindow, someText)? [Consequences are operationally insignificant -- in both cases the text is shown on the terminal window -- but can be very serious in the design of class hierarchies and a "wrong" choice can lead to convoluted and hard to maintain code.] I would therefore argue that the mainstream way of doing OOP (class-based, single-dispatch) is hard because it IS UNNATURAL and does not correspond to how humans think about the world. Generic methods from CLOS are closer to my way of thinking, but, alas, this is not widespread approach. Given these problems, how/why did it happen that the currently mainstream way of doing OOP became so popular? And what, if anything, can be done to dethrone it?

• When failure is a feature

  Warning: this post is going to be slightly off-topic and non-technical. Well, not computer science technical at least. I was reading an article in SciAm this morning about the possibility of a robot uprising. Dont laugh yet, this is a very real, if still quite remote possibility. The main idea that was described was that AI could rise one day to self-awareness and to an ability to improve itself through self-replication beyond human abilities to control it. Sure, thats one possibility, and some...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• SSH access failure from Ubuntu 12.04 LTS VM

  - by begueradj

  I installed 2 VMs on VirtualBox. VM 1: Windows XP with FreeSSHd and PuTTY installed.IP address: 10.0.0.2 VM 2: Ubuntu 12.04 LTS Server Edition with OpenSSH installed.IP address: 10.0.0.3 From VM 1, I run PuTTY with the IP address of VM 2 (10.0.0.3) and port number 22. I get prompted to input the username and password of VM 2 and everything works fine.From VM 2, I run on the terminal (Ubuntu): ssh [email protected] , I get prompted to enter the password of VM 1. I do so, but it says my password is invalid (while it is the correct one). I even deactived the Firewall on VM 1, but still the problem is here: my password is not accepted from VM 2. Is this due to some settings maybe I must do on VM 1 (Windows XP) so as I can access it with SSH ? Maybe it has something to do with the Firewall of Windows XP ?Important information: ping 10.0.0.2 from VM 1 and ping 10.0.0.3 from VM 2 are working successfully.

• Shuttle FB51 mobo does not boot with external USB drive attached [closed]

  - by user127236

  I am repurposing an old Alienware desktop as a home media server. The PC is based on the Shuttle FB51 motherboard. The BIOS is a Phoenix Version 6.00 PG, release date 12/16/2002. I have loaded Ubuntu 12.04 LTS on the internal hard drive. I am using a Western Digital WD Elements 1.5 TB USB 2.0 Desktop External Hard Drive for media storage. When the external drive is plugged in and the PC is powered on, it freezes very early in the BIOS self-test, even before it begins the memory test. If I unplug the drive, the self-test proceeds without further problems. I can plug the USB drive back in when the self-test is complete, and Ubuntu will boot and find the external drive normally. I've tried several changes to the BIOS setup without finding a cure for the boot issue. Any assistance gratefully accepted. JGB

• Partitioning a 128GB SSD and 500GB HDD

  - by Gladen

  So I have a 128GB SSD and 500GB HDD. I want to reïnstall my laptop and put Ubuntu 12.10 on this setup. I already looked around on the internet and came up with this partitioning schema: about 2GB of swap on the SSD (I got 4GB of RAM in my laptop) / using the rest of that space /home on the HDD So I was wondering, are there any better schemes or extra partitions that I should consider putting on a particular drive? Thanks in advance! :)

• Black frame around screen after HDMI connection failure

  - by Wolter Hellmund

  I was trying to watch a movie in my computer through the TV, so I connected both with an HDMI cable. I was unable to have a successful setup (the colors were all weird on the TV and the screen size, incorrect), I tried many resolutions using the nvidia-settings application and somehow my screen got framed by a black border and after that I have been unable to remove it, even after restarting the computer and not being connected to the HDMI cable anymore. I am using Ubuntu 11.10 amd64, my GPU is an nVidia GeForce 8600M GT and I am using the propietary driver version 280. The problem is due to some setting with my account only. I logged in to the guest session and the resolution is right there. Also, my desktop "thinks" the resolution is right (i.e. 1280x800), but it must be right in another scale because there is pixel area occupied by the black frame.

• Cannot read/write a second drive in MBP 13

  - by Carlos

  I changed my original HDD for a SDD earlier this year and I just got one more SSD for my MBP 13 (2012) that I used to replace DVD drive. I'm using Mountain Lion. The SSD looks to be recognized allright, but I can't format it. Then I removed the main drive and tried the new one as the main drive and did the boot using a USB drive with MAC OS and everyhing worked as it should (like I just had one drive). However when I bring the first drive back together with the second they both show up but I can't use it. Seems like I have no permission, but when I look at it's properties it says I can read and write to it. Any ideas? Thanks a lot!

• Modern OpenGL context failure [migrated]

  - by user209347

  OK, I managed to create an OpenGL context with wglcreatecontextattribARB with version 3.2 in my attrib struct (So I have initialized a 3.2 opengl context). It works, but the strange thing is, when I use glBindBuffer e,g. I still get unreferenced linker error, shouldn't a newer context prevent this? I'm on windows BTW, Linux doesn't have to deal with older and newer contexts (it directly supports the core of its version). The code: PIXELFORMATDESCRIPTOR pfd; HGLRC tmpRC; int iFormat; if (!(hDC = GetDC(hWnd))) { CMsgBox("Unable to create a device context. Program will now close.", "Error"); return false; } ZeroMemory(&pfd, sizeof(pfd)); pfd.nSize = sizeof(pfd); pfd.nVersion = 1; pfd.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL | PFD_DOUBLEBUFFER; pfd.iPixelType = PFD_TYPE_RGBA; pfd.cColorBits = attribs->colorbits; pfd.cDepthBits = attribs->depthbits; pfd.iLayerType = PFD_MAIN_PLANE; if (!(iFormat = ChoosePixelFormat(hDC, &pfd))) { CMsgBox("Unable to find a suitable pixel format. Program will now close.", "Error"); return false; } if (!SetPixelFormat(hDC, iFormat, &pfd)) { CMsgBox("Unable to initialize the pixel formats. Program will now close.", "Error"); return false; } if (!(tmpRC=wglCreateContext(hDC))) { CMsgBox("Unable to create a rendering context. Program will now close.", "Error"); return false; } if (!wglMakeCurrent(hDC, tmpRC)) { CMsgBox("Unable to activate the rendering context. Program will now close.", "Error"); return false; } strncpy(vers, (char*)glGetString(GL_VERSION), 3); vers[3] = '\0'; if (sscanf(vers, "%i.%i", &glv, &glsubv) != 2) { CMsgBox("Unable to retrieve the OpenGL version. Program will now close.", "Error"); return false; } hRC = NULL; if (glv > 2) // Have OpenGL 3.+ support { if ((wglCreateContextAttribsARB = (PFNWGLCREATECONTEXTATTRIBSARBPROC)wglGetProcAddress("wglCreateContextAttribsARB"))) { int attribs[] = {WGL_CONTEXT_MAJOR_VERSION_ARB, glv, WGL_CONTEXT_MINOR_VERSION_ARB, glsubv,WGL_CONTEXT_FLAGS_ARB, 0,0}; hRC = wglCreateContextAttribsARB(hDC, 0, attribs); wglMakeCurrent(NULL, NULL); wglDeleteContext(tmpRC); if (!wglMakeCurrent(hDC, hRC)) { CMsgBox("Unable to activate the rendering context.

  I have logged into ubuntu one using a browser successfully. But using the very same login email address and password in the windows client 3.02 gets me an 'authentication failed' message. I am 100% sure I used the same email address and password. My password does not contain any non-ascii characters. Someone suggested to use an older version of the client. Where could i possibly download a complete installer?

• Have optical drive connectors changed in the last year?

  - by Zippityboomba

  In early 2010 my motherboard freaked out, and I was able to drop in a new board and connect my two DVD drives that were initially bought in 2005. Tonight my new components arrived to build my next system, and I figured I'd just reuse the old DVD drives. Surprise, the long flat connector cable has no mate on the new motherboard. Reckon I'll just pick up a new DVD drive for $25, but what gives? Thanks!

• What happens to the storage capacity when I uninstall Ubuntu?

  - by shole1202

  I used the wubi installer for Ubuntu 12.04. After having trouble with getting the Operating System to boot, I tried uninstalling it with wubi. From 'My Computer' (in Windows 7), I noticed the maximum capacity of my hard drive drop from 256gb to 238gb. I have tried using some methods with the command prompt to locate the missing storage, but Windows now only recognizes that the storage on the disk to have 238gb instead of the original 256. Is there any way to recover that memory?

• Boot failure on Ubuntu 11.04

  - by B Seven

  I was using my laptop with Ubuntu without problem for a few months. I did not update any software or install any OS updates. This morning when it started, I got error: no such device:.... error: no such disk error: you need to load the kernel first. Press any key to continue... Then takes me back to GRUB menu. Both Ubuntu option and recovery mode option show the same thing (above). What does this mean? How do I fix it? Since I did not install anything new, does it mean the SSD is dying (again)? How to check the SSD to and fix any file system errors? Ubuntu 11.04 EDIT: Just remembered something: when the system was shutting down, it did not turn off. There were a bunch of weird output statements, and I assumed the system had shut down so I turned it off with the power button. Perhaps something got corrupted because of that.
