  • How do I set up nvidia graphics adapter to put out 1080p, it seems to be using interlace mode>

    - by keepitsimpleengineer
    After upgrading to 12.04, my mythbuntu client/server seems to be running in 1080i, the clue comes from: [ 1176.117] (II) NVIDIA(0): Setting mode "1920x1080_60i" [ 1231.340] (II) NVIDIA(0): Setting mode "DFP-1:1920x1080_60@1920x1080+0+0" This is from Xorg.0.log. This whole thing started from video tearing when watching Mythtv recordings. It didn't happen in 10.10. Should I use "TVStandard" "HD1080p" in the screen section since this is a dedicated HTPC? It only connects to an HDTV (1080p) via hdmi. Here is the current xorg.conf file: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 270.29 (buildd@allspice) Fri Feb 25 14:42:07 UTC 2011 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup # InputDevice "Keyboard0" "CoreKeyboard" # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup # InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "Files" FontPath "unix/:7100" EndSection # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup #Section "InputDevice" # # generated from default # Identifier "Mouse0" # Driver "mouse" # Option "Protocol" "auto" # Option "Device" "/dev/psaux" # Option "Emulate3Buttons" "no" # Option "ZAxisMapping" "4 5" #EndSection # commented out by update-manager, HAL is now used and auto-detects devices # Keyboard settings are now read from /etc/default/console-setup #Section "InputDevice" # # generated from default # Identifier "Keyboard0" # Driver "kbd" #EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "SAMSUNG" HorizSync 26.0 - 81.0 VertRefresh 24.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GT 240" Option "TripleBuffer" "1" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "DFP: nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection After a little digging, the question changes slightly, to wit... Per Chapter 19 of nvidia README... "If the EDID for the display device reported a preferred mode timing, and that mode timing is considered a valid mode, then that mode is used as the "nvidia-auto-select" mode." The EDID for my HDMI connected LCD monitor says use first device as preferred. Prefer first detailed timing : Yes Also: (--) NVIDIA(0): EDID maximum pixel clock : 230.0 MHz The list: (from startx -- -verbose 6 ) (--) NVIDIA(0): Detailed Timings: (--) NVIDIA(0): 1920 x 1080 @ 60 Hz (--) NVIDIA(0): Pixel Clock : 148.50 MHz (--) NVIDIA(0): HRes, HSyncStart : 1920, 2008 (--) NVIDIA(0): HSyncEnd, HTotal : 2052, 2200 (--) NVIDIA(0): VRes, VSyncStart : 1080, 1084 (--) NVIDIA(0): VSyncEnd, VTotal : 1089, 1125 (--) NVIDIA(0): H/V Polarity : +/+ This is the actual mode selected: (from xorg.0.log) (--) NVIDIA(0): 1920 x 1080 @ 60 Hz (--) NVIDIA(0): Pixel Clock : 74.18 MHz (--) NVIDIA(0): HRes, HSyncStart : 1920, 2008 (--) NVIDIA(0): HSyncEnd, HTotal : 2052, 2200 (--) NVIDIA(0): VRes, VSyncStart : 1080, 1084 (--) NVIDIA(0): VSyncEnd, VTotal : 1094, 1124 (--) NVIDIA(0): H/V Polarity : +/+ (--) NVIDIA(0): Extra : Interlaced (--) NVIDIA(0): CEA Format : 5 So my HTPC is down-converting to 1080i and then the Monitor is up-converting to 1080p How can I fix this, please?

  • Data Structures for Logic Games / Deduction Rules / Sufficient Set of Clues?

    - by taserian
    I've been cogitating about developing a logic game similar to Einstein's Puzzle , which would have different sets of clues for every new game replay. What data structures would you use to handle the different entities (pets, colors of houses, nationalities, etc.), deduction rules, etc. to guarantee that the clues you provide point to a unique solution? I'm having a hard time thinking about how to get the deduction rules to play along with the possible clues; any insight would be appreciated.

  • Monitor reset itself and now I can't set the resolution/settings back to how it was before

    - by verve
    I've had my LG 24" widescreen monitor since 2009 and 2 weeks ago I noticed the monitor turned itself off (never had it done this before) so I switched it back on to find all the settings like gamma, resolution etc. different = looked like it had been reset. Everyone in the house swears they never unplugged and plugged it back in. When I opened a webpage the fonts and zoom on the pages were different and my desktop was strange too; fonts of the icons were different etc. The screen seems blurry and when I watch movies the faces look distorted so I thought I would try to first figure out the resolution it used to be but when I go under "Adjust screen resolution" none of the options work and there is no recommended resolution marked; all the options stretch out the screen and looks terrible so right now I have it set to the least distorted one. Then since the resolution wasn't working I set the other manual settings(done by physical buttons on the monitor) back to how it used to be (luckily, I had written these down). The monitor looks better but the resolution makes it a strain to use. I thought maybe some Windows update caused this crap so I tried to System Restore: didn't work. What went wrong? A few questions: 1) What was the likely cause of the monitor shutting down itself and screwing up the settings I have been using since the day I bought the monitor? 2) Why have the fonts changed everywhere unless this is a HDD/video card problem? 3) How do I find the perfect resolution it used to be? The monitor wants me to set it to 1920 x 1080 but that isn't one of the options although I don't remember what resolution I used before. I use the 16:9 setting while I try the available resolution options but nothing looks good! How do I find what it used to be?

  • Code Analysis Rule Sets in Visual Studio 2010

    - by Anthony Trudeau
    Microsoft Visual Studio 2010 introduces the concept of rule sets when configuring code analysis.  This is a valuable change from Visual Studio 2008 that I didn't even realize I wanted.  Visual Studio 2008 by default selected all rules and then you had to remove rules on an item by item basis. The rule sets fall into logical groups including "Microsoft All Rules", "Microsoft Basic Correctness Rules", "Microsoft Security Rules", et al.  And within the project properties you can select one rule set, multiple rule sets, or you can define your own rule set based upon another. Selecting a single rule set is obviously the easiest option.  The default rule set when you create a new project is the "Microsoft Minimum Recommended Rules".  However, in my opinion the recommended rules are just too permissive.  For that reason you might want to change your rule set to "Microsoft All Rules" until you get around to creating your own rule set; or alternately you can select multiple rule sets which is an option from the rule set combo box.  The Visual Studio documentation has comprehensive help on what is contained within the rule sets. Creating your own rule set is easy if not obvious.  You need to start a rule set from an existing rule set.  To get started select a rule set in the combo box within the Code Analysis tab of the project properties.  I selected the "Microsoft All Rules" for my rule set, but you may find it easier to start with the "Microsoft Minimum Recommended Rules" if your rules are on the more permissive side. Once your rule set is selected click the Open button.  This will display a dialog that is similar in composition to the rules selection from Visual Studio 2008.  Browsing through the tree view you can select or deselect individual rules within their categories; and you can indicate that the rules are flagged as errors instead of the default which is a warning.  A nice touch to the form is that you get a help pane when you select an individual rule.  That helped me considerably when I first configured my rule set. Once you have finished selecting your rules click the Save tool button, specify a location and name, and click the Save button on the Save As dialog.  Once you're back on the Code Analysis tab you'll choose the Browse option within the combo box and open the file you just created.

  • Why should I Use ASP.NET Membership security model?

    - by ListenToRick
    I'm updating my website at the moment and figure that if I am to update my login/security mode, now is a good time. I have looked through the Membership model which is included in ASP.NET but I'm convinced that it will provide any benefit apart from being familiar to other .NET deevlopers. There seems to be quite a lot of documentation for it, but little discussion for why its worth the effort. Can anybody shed some light upon this?

  • How to modify/replace option set file when building from command line?

    - by Heinrich Ulbricht
    I build packages from a batch file using commands like: msbuild ..\lib\Package.dproj /target:Build /p:config=%1 The packages' settings are dependent on an option set: <Import Project="..\optionsets\COND_Defined.optset" Condition="'$(Base)'!='' And Exists('..\optionsets\COND_Defined.optset')"/> This option set defines a conditional symbol many of my packages depend on. The file looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <DCC_Define>CONDITION;$(DCC_Define)</DCC_Define> </PropertyGroup> <ProjectExtensions> <Borland.Personality>Delphi.Personality.12</Borland.Personality> <Borland.ProjectType>OptionSet</Borland.ProjectType> <BorlandProject> <Delphi.Personality/> </BorlandProject> <ProjectFileVersion>12</ProjectFileVersion> </ProjectExtensions> </Project> Now I need two builds: one with the condition defined and one without. My attack vector would be the option set file. I have some ideas on what to do: write a program which modifies the option set file, run this before batch build fiddle with the project files and modify the option set path to contain an environment variable, then have different option sets in different locations But before starting to reinvent the wheel I'd like to ask how you would tackle this task? Maybe there are already means meant to support such a case (like certain command line switches, things I could configure in Delphi or batch file magic).

  • How to set a key binding to make Emacs as transparent/opaque as I want?

    - by Vivi
    I want to have a command in Emacs to make it as opaque/transparent as I want (refer to the fabulous question that pointed out that transparency is possible in Emacs, and the EmacsWiki page linked there which has the code I am using below). The EmacsWiki code sets "C-c t" to toggle the previously set transparency on and off: ;;(set-frame-parameter (selected-frame) 'alpha '(<active> [<inactive>])) (set-frame-parameter (selected-frame) 'alpha '(85 50)) (add-to-list 'default-frame-alist '(alpha 85 50)) enter code here(eval-when-compile (require 'cl)) (defun toggle-transparency () (interactive) (if (/= (cadr (find 'alpha (frame-parameters nil) :key #'car)) 100) (set-frame-parameter nil 'alpha '(100 100)) (set-frame-parameter nil 'alpha '(85 60)))) (global-set-key (kbd "C-c t") 'toggle-transparency) What I would like to do is to be able to choose the % transparency when I am in Emacs. If possible, I would like a command where I type for example "C-c t N" (where N is the % opaqueness) for the active frame, and then "M-c t N" for the inactive window. If that can't be done like that, then maybe a command where if I type "C-c t" it asks me for the number which gives the opaqueness of the active window (and the same for the inactive window using "M-c t"). Thanks in advance for your time :) Below are just some comments that are not important to answer the question if you are not interested: I really want this because when I told my supervisor I was learning Emacs he said TexShop is much better and that I am using software from the 80's. I told him about the wonders of Emacs and he said TexShop has all of it and more. I matched everything he showed me except for the transparency (though he couldn't match the preview inside Emacs from preview-latex). I found the transparency thing by chance, and now I want to show him Emacs rules! I imagine this will be a piece of cake for some of you, and even though I could get it done if I spent enough time trying to learn lisp or reading around, I am not a programmer and I have only been using Emacs and a mac for a week. I am lost already as it is! So thanks in advance for your time and help - I will learn lisp eventually!

  • Engine Rendering pipeline : Making shaders generic

    - by fakhir
    I am trying to make a 2D game engine using OpenGL ES 2.0 (iOS for now). I've written Application layer in Objective C and a separate self contained RendererGLES20 in C++. No GL specific call is made outside the renderer. It is working perfectly. But I have some design issues when using shaders. Each shader has its own unique attributes and uniforms that need to be set just before the main draw call (glDrawArrays in this case). For instance, in order to draw some geometry I would do: void RendererGLES20::render(Model * model) { // Set a bunch of uniforms glUniformMatrix4fv(.......); // Enable specific attributes, can be many glEnableVertexAttribArray(......); // Set a bunch of vertex attribute pointers: glVertexAttribPointer(positionSlot, 2, GL_FLOAT, GL_FALSE, stride, m->pCoords); // Now actually Draw the geometry glDrawArrays(GL_TRIANGLES, 0, m->vertexCount); // After drawing, disable any vertex attributes: glDisableVertexAttribArray(.......); } As you can see this code is extremely rigid. If I were to use another shader, say ripple effect, i would be needing to pass extra uniforms, vertex attribs etc. In other words I would have to change the RendererGLES20 render source code just to incorporate the new shader. Is there any way to make the shader object totally generic? Like What if I just want to change the shader object and not worry about game source re-compiling? Any way to make the renderer agnostic of uniforms and attributes etc?. Even though we need to pass data to uniforms, what is the best place to do that? Model class? Is the model class aware of shader specific uniforms and attributes? Following shows Actor class: class Actor : public ISceneNode { ModelController * model; AIController * AI; }; Model controller class: class ModelController { class IShader * shader; int textureId; vec4 tint; float alpha; struct Vertex * vertexArray; }; Shader class just contains the shader object, compiling and linking sub-routines etc. In Game Logic class I am actually rendering the object: void GameLogic::update(float dt) { IRenderer * renderer = g_application->GetRenderer(); Actor * a = GetActor(id); renderer->render(a->model); } Please note that even though Actor extends ISceneNode, I haven't started implementing SceneGraph yet. I will do that as soon as I resolve this issue. Any ideas how to improve this? Related design patterns etc? Thank you for reading the question.

  • How do you set up the directory structure for a multilingual site without duplicating content?

    - by Ricardo
    I want to make a website in two languages. I've looked around and settled on the directory option of separating both languages. How do I make it work? Let's say I have the following three files for the landing homepage, the English page and the Spanish page: http://www.domain.com/index.html http://www.domain.com/en/index.html http://www.domain.com/es/index.html Let's also say that /index.html will be in English, with a link to /es/index.html. In turn, /es/index.html will have a link to the English version. Would this be back to /index.html or to /en/index.html. How do I get both English versions (the one at the root and the one in the directory) to actually be the same file in the same directory? I'm new to this, so I'm not using any scripts yet. To me, the obvious solution is to duplicate both English versions and have the one at the root point to files under the /en/ directory, but I'm not a fan of duplication and I've learned that search engines really frown upon that. Anyone point me in the right direction?

  • How to set Monday as the first day of the week in GNOME Calendar applet?

    - by Jonik
    What is the recommended way to change the first day of the week to Monday (instead of Sunday, as in the screenshot below)? I couldn't find anything related in Clock Preferences, nor in System - Preferences, or System - Administration. This probably has something to do with tweaking locales, so here's (possibly relevant) output from locale: LANG=en_US.utf8 LC_CTYPE="en_US.utf8" LC_NUMERIC="en_US.utf8" LC_TIME="en_US.utf8" ... LC_ALL= NB: I want to keep English as the UI language both in GNOME and on command line. Dates are currently displayed like this (e.g. ls -l): 2010-10-06 15:32, and I also want to keep that as it is.

  • Where can I find information on the Get, Set and Address methods for multidimensional System.Array i

    - by Rob Smallshire
    System.Array serves as the base class for all arrays in the Common Language Runtime (CLR). According to this article, For each concrete array type, [the] runtime adds three special methods: Get/Set/Address. and indeed if I disassemble this C# code, int[,] x = new int[1024,1024]; x[0,0] = 1; x[1,1] = 2; x[2,2] = 3; Console.WriteLine(x[0,0]); Console.WriteLine(x[1,1]); Console.WriteLine(x[2,2]); into CIL I get, IL_0000: ldc.i4 0x400 IL_0005: ldc.i4 0x400 IL_000a: newobj instance void int32[0...,0...]::.ctor(int32, int32) IL_000f: stloc.0 IL_0010: ldloc.0 IL_0011: ldc.i4.0 IL_0012: ldc.i4.0 IL_0013: ldc.i4.1 IL_0014: call instance void int32[0...,0...]::Set(int32, int32, int32) IL_0019: ldloc.0 IL_001a: ldc.i4.1 IL_001b: ldc.i4.1 IL_001c: ldc.i4.2 IL_001d: call instance void int32[0...,0...]::Set(int32, int32, int32) IL_0022: ldloc.0 IL_0023: ldc.i4.2 IL_0024: ldc.i4.2 IL_0025: ldc.i4.3 IL_0026: call instance void int32[0...,0...]::Set(int32, int32, int32) IL_002b: ldloc.0 IL_002c: ldc.i4.0 IL_002d: ldc.i4.0 IL_002e: call instance int32 int32[0...,0...]::Get(int32, int32) IL_0033: call void [mscorlib]System.Console::WriteLine(int32) IL_0038: ldloc.0 IL_0039: ldc.i4.1 IL_003a: ldc.i4.1 IL_003b: call instance int32 int32[0...,0...]::Get(int32, int32) IL_0040: call void [mscorlib]System.Console::WriteLine(int32) IL_0045: ldloc.0 IL_0046: ldc.i4.2 IL_0047: ldc.i4.2 IL_0048: call instance int32 int32[0...,0...]::Get(int32, int32) IL_004d: call void [mscorlib]System.Console::WriteLine(int32) where the calls to the aforementioned Get and Set methods can be clearly seen. It seems the arity of these methods is related to the dimensionality of the array, which is presumably why they are created by the runtime and are not pre-declared. I couldn't locate any information about these methods on MSDN and their simple names makes them resistant to Googling. I'm writing a compiler for a language which supports multidimensional arrays, so I'd like to find some official documentation about these methods, under what conditions I can expect them to exist and what I can expect their signatures to be. In particular, I'd like to know whether its possible to get a MethodInfo object for Get or Set for use with Reflection.Emit without having to create an instance of the array with correct type and dimensionality on which to reflect, as is done in the linked example.

  • Can I set my Optimus Nvidia card to run Unity3D with bumblebee?

    - by manuhalo
    I'd like to know whether I can run compiz on my Nvidia card to speed things up. It's a Dell XPS15 laptop but I'm mostly using it as a desktop, so battery life is not important.

  • Is there a quasi-standard set of attributes to annotate thread safety, immutability etc.?

    - by Eugene Beresovksy
    Except for a blog post here and there, describing the custom attributes someone created, but that do not seem to get any traction - like one describing how to enforce immutability, another one on Documenting Thread Safety, modeling the attributes after JCIP annotations - is there any standard emerging? Anything MS might be planning for the future? This is something that should be standard, if there's to be any chance of interoperability between libraries concurrency-wise. Both for documentation purposes, and also to feed static / dynamic test tools. If MS isn't doing anything in that direction, it could be done on CodePlex - but I couldn't find anything there, either. <opinion>Concurrency and thread safety are really hard in imperative and object-languages like C# and Java, we should try to tame it, until we hopefully switch to more appropriate languages.</opinion>

  • Do we set the bar too high by requiring that code tests not suffer from buffer overflow?

    - by brice
    We are currently recruiting for a Junior Developer position working mainly in C on Linux. As part of the process, we require candidates to complete a code test at their leisure in C. So far we have rejected two candidates on the basis that their code, although readable and in one case rather idiomatic, suffered from buffer overflow errors due to unbounded buffer writes. Are buffer overflows acceptable from a graduate developer? Are we setting the bar too high? What is the expected capability of graduate/Junior engineers? [Edit]: We explicitly ask for error-checked, production quality code. We provide a test & build framework for the candidates

  • How to set up an environment for android app development?

    - by The Dark Knight
    I have been researching for sometime now regarding the process to install android sdk and associated tools . After visiting Android Developers page, i first installed the android sdk and then installed eclipse plugins for my indigo version from the install softwares options.However, it is mentioned in the developers page : Download the Android SDK. Install the ADT plugin for Eclipse (if you’ll use the Eclipse IDE). Download the latest SDK tools and platforms using the SDK Manager. I have downloaded the sdk and installed the adt plugins for eclipse.I just need to point the eclipse towards the location of the sdk. However, i am stuck at the last step which is asking me to download the latest tools using the sdk manager. The manager interface pops up and i see a lot of options there. I don't know which ones i must select and install. If some one can help me out here and tell me which options to choose and install(if possible, with a screen shot), it will be very beneficial for me.

  • Limit JavaScript and CSS files on ASP.NET MVC 2 Master Page based on Model and View content

    - by Zack Peterson
    I want to include certain .js and .css files only on pages that need them. For example, my EditorTemplate DateTime.ascx needs files anytimec.js and anytimec.css. That template is applied whenever I use either the EditorFor or EditorForModel helper methods in a view for a model with a DateTime type value. I've put this condition into the <head> section of my master page. It checks for a DateTime type property in the ModelMetadata. <% if (this.ViewData.ModelMetadata.Properties.Any(p => p.ModelType == typeof(DateTime))) { %> <link href="../../Content/anytimec.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/anytimec.js" type="text/javascript"></script> <% } %> This has two problems: Fails if I have nested child models of type DateTime Unnecessarily triggered by views without EditorFor or EditorForModel methods (example: DisplayForModel) How can I improve this technique?

  • How do you retrieve the array adapter currently set for a spinner? Android OS, Droid

    - by Sean
    Looking to create a menu toggle that switches between two possible arrays for a spinner. For example, if the spinner is set to show array A, then when I press this menu button, I want the spinner to be set to array B. If I press it again, I want it to be set back to array A. I can handle the if/then statements and all, but how do I call the spinner's array adapter? I know how to call its value using getSelectedItemPosition(); but is there a similar method for retrieving WHICH array it is currently set to?

  • How can I specify resources in an MVVM view model?

    - by gix
    Suppose I want to show list of objects where each object should have a name and a suitable image (for example MenuItems with Icons, or buttons with text and image). All examples and programs exposed the image in the viewmodel as a path to a PNG file and then bound the Source of an Image to that. But what if I want to use vector images (for example as a DrawingImage in a local ResourceDictionary)? Exposing the DrawingImage from the view model seems bad because I would have to store a reference to the application/window/user control/... (and it is advised to not expose such XAML objects from view models). So a better approach would be to use a string identifier in the view model and then somehow select the appropriate resource. If that identifier is the resource key this snippet looks tempting but does not work: <Image Source="{StaticResource {Binding Icon}}"/> I found two workarounds for that though they did not work for me. The first one was using a normal binding to the icon with a converter that looked up the resource in Application.Current. This does not work if the resource is stored somewhere else I think (and the situation where I initially bumped into this problem had no Application running yet since it was a Window choosing the Application to launch!). The second workaround was using a markup extension derived from StaticResourceExtension that fetched its ResourceKey from the passed binding: <Image Source="{local:BindableStaticResource {Binding Icon}"/> This one looks really neat because it could use local resources, also be used for other things. But when using it I always got an exception ("Resource named {FooIcon} could not be found.", showing the correct XAML file and position of the extension). Even an empty resource extension derived from StaticResourceExtension that just passed the resource key to the base constructor did not work and I cannot explain why. Just using StaticResourceExtension worked just fine. Any ideas how I could fix the second approach, or even better solutions? Edit I noticed that it does work when used directly like this: <Window> <Window.Resources> <DrawingImage x:Key="SomeIcon"/> </Window.Resources> <Image Source="{BindableStaticResource {Binding Icon}}"/> </Window> but fails for example in a DataTemplate. Though a normal StaticResourceExtension works on both occasions so I am puzzled what is going wrong.

  • How do you use technology to memorize set of terms?

    - by user49767
    Always there are few set of items needs to be memorized in short span of time. Here are my following cases. 1) My Job requires some set of items needs to be memorized. 2) I am a developer who has to learn 150+ tags within next 3 days. 3) Fix developer/support has to remember minimum of 125+ tags (set of possible values). 4) It is better if team's SQL developer knows all the table and columns in my database. 5) When guys join new department or job. Memorizing few related items will definitely gives some benefit. Most of the cases, I suggest people to understand the domain better and nothing wrong in using google (but remember correct search-word). But recently I came across a junior developer who took lot of effort in memorizing set of things (150+ table structures, fix protocol tags, almost 300+ configuration items from property file) and was very very successful in his job and was swift in responding for support queries. Needless to say he is smart worker too (not a dumb guy). When I try to recollect some of the successful employees I met, they were so good in remembering entire schema and they did in short span of time. But I don't argue that memorizing alone gives success, but it greatly helps when situation demands. Here my question is, I am not good at remembering things, but it shouldn't be lame excuse. Hence I am evaluating using technolgies better to memorize set of items. Not very much interested in memory techniques (mnemoninc, photography memory, etc..). Even I have recorded 100+ items and listen to that whenever I found free time, defintely there were some fruitful result. Now I need your suggestion about what are all the ways to exploit technology to memorize. There could be so many reason why guys remember a subject (passionate, essential, author, creator, responsbile). Not interested in dissecting why guys remeber. Rather much interested in using ways, and techniques (cheat sheet...) to remember a set of itmes. Note : I appreciate, encourage people who could rephrase my question better. Note : I have kept couple of cheat-sheet close to my monitor, honestly it did not help me :).

  • How can I set up FakeRAID/SoftRAID using mdadm without losing data?

    - by Danatela
    There is RAID0 of 2 drives connected through Silicon Image 3132 SATA SoftRAID controller. Under Windows it was partitioned as one dynamic GPT-disk having 4 TB NTFS volume. There is a lot of music and movies on the drive. I'm trying to get him to be seen under Ubuntu as a single disk, not as 2 by 2 terabytes. I tried to read it through dmraid, had no success, it is not displayed in /dev/mapper. Also tried to configure the kernel, but did not find anything suspicious, the driver for my controller was on. There is also a driver from the manufacturer, but it is only available for RHEL and SLES. Here it's reported that SoftRAID is supported by the kernel, but apparently not completely. If I thrust drives in the AMD controller, built into the motherboard, the drive is seen as a single, but the data is lost. I know about mdadm that it is able to ditch all the information on the disks. So, is it possible to somehow create an array without actually recording information on used drives and to make the system correctly identify sections on it later? Information about the array: /dev/sdf - Disk 0 /dev/sdg - Disk 1 Array type: Stripe Block Size: 64KB Also, a device /dev/md1 is created using command mknod /dev/md1 b 9 1
