  • Large, high performance object or key/value store for HTTP serving on Linux

    - by Tommy
    I have a service that serves images to end users at a very high rate using plain HTTP. The images vary between 4 and 64kbytes, and there are 1.300.000.000 of them in total. The dataset is about 30TiB in size and changes (new objects, updates, deletes) make out less than 1% of the requests. The number of requests pr. second vary from 240 to 9000 and is dispersed pretty much all over, with few objects being especially "hot". As of now, these images are files on a ext3 filesystem distributed read only across a large amount of mid range servers. This poses several problems: Using a fileysystem is very inefficient since the metadata size is large, the inode/dentry cache is volatile on linux and some daemons tend to stat()/readdir() it's way through the directory structure, which in my case becomes very expensive. Updating the dataset is very time consuming and requires remounting between set A and B. The only reasonable handling is operating on the block device for backup, copying, etc. What I would like is a deamon that: speaks HTTP (get, put, delete and perhaps update) stores data it in an efficient structure. The index should remain in memory, and considering the amount of objects, the overhead must be small. The software should be able to handle massive connections with slow (if any) time needed to ramp up. Index should be read in memory at startup. Statistics would be nice, but not mandatory. I have experimented a bit with riak, redis, mongodb, kyoto and varnish with persistent storage, but I haven't had the chance to dig in really deep yet.

  • my cpu won't start. all fan were spinning for a second then nothing happen

    - by Tommy
    I need help about this.. I'm from Malaysia.. Back then my cpu is all okay..and it's 4 year old.. I think this question is answered before but i'm still don't understand.. when i plugged my cpu..turn it on and all of the fan (graphic card, mobo fan and PSU fan) were spinning just for a second than nothing happen.. I don't know if it is because of the PSU or my mobo.. I sent my cpu to the shop and they said it must be the mobo.. They tell me to change my mobo and PSU also..and it cost over 100 buck (rm300 in Malaysia). and i'm real 'dry' right now. My whole data is inside the HDD. School projects, photos, games, and many..I really-really need my cpu back alive.. My mobo is MSI MS-7529 with dual core chips. My PSU is ATX-480W. the PC store guy said i need to change to new ASUS mobo if I want. I dont know what type it is but Then he tell me to change my PSU also because he don't think my old PSU (ATX-480W) ain't compatible to the new mobo.. I was very need a help from you techie guys.. sorry for my terrible English..

  • Batch converting video from avc1 to xvid

    - by Tommy Brunn
    I need a way to batch convert 720p video files from avc1 to xvid in Ubuntu 10.04. I'm not terribly concerned about file size, but I do wish to retain the picture quality as much as possible. I believe the audio is encoded as aac, which is fine for my purposes. What would be the best and easiest way to do this? I've tried using Handbrake. During my first attempt, I had it using ffmpeg to convert to MPEG-4, but that just gave me a super-low quality video at twice the file size. Trying h.264 now, so we'll see how that works out. But just in case it doesn't pan out so well, what other ways do you recommend? I was thinking I'd write a bash script to reencode the files one by one, but the problem is that I have very little knowledge about codecs and containers and whatnot - so I wouldn't know what parameters I would pass ffmpeg/mencoder.

  • Keyboard no longer works when entering BIOS

    - by Tommy
    I am trying to boot from USB so I can install a couple different Linux distros. I can enter the BIOS, but as soon as I enter the BIOS the keyboard lights switch off (Num Lock and Caps Lock) and I cannot use the keyboard to do anything in the BIOS or even exit or restart the PC using Ctrl+Alt+Del or do anything at all with the keyboard. But as soon as I boot back into Windows, everything is fine... I've never had this problem before and some Googling hasn't helped. I've tried using a few other keyboards and simply unplugging/replugging the keyboards, but it didn't work. Is there anything I can do in Windows to maybe find out why the keyboard isn't working in the BIOS screen? In the Device Manager, all the drivers are up to date and there are no conflicts.

  • SharePoint 2010: CheckSuspiciousPhysicalPath exception

    - by Tommy Jakobsen
    I just installed SharePoint 2010 on my Windows Server 2008 R2 x64 server with SQL Server 2008. Everything is installed on this single server, and I configured SharePoint 2010 as described here: http://sharepoint.microsoft.com/blogs/fromthefield/Lists/Posts/Post.aspx?ID=112 Everything installed correct, and the SQL databases were created. But when I try to access the administration site through http://server:47632/_admin/adminconfigintro.aspx, I get the following exception: [HttpException] at System.Web.Util.FileUtil.CheckSuspiciousPhysicalPath(String physicalPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.HttpContext.GetFilePathData() at System.Web.Configuration.CustomErrorsSection.GetSettings(HttpContext context, Boolean canThrow) at System.Web.HttpResponse.ReportRuntimeError(Exception e, Boolean canThrow, Boolean localExecute) at System.Web.HttpRuntime.FinishRequest(HttpWorkerRequest wr, HttpContext context, Exception e) The same error occurs when accessing http://server:47632/. Do you have any ideas whats causing this? I haven't been able to find anything about this issue. Edit 1: I just tried reinstalling SharePoint 2010 while monitoring the error log.

  • AssemblyCleanup() after test fail/exception

    - by Tommy Jakobsen
    Hello, I'm running a few unit tests that requires a connection to the database. When my test project get initialized, a snapshot of the database is created, and when tests are done the database gets restored back to the snapshot. Here is the implementation: [TestClass] public static class AssemblyInitializer { [AssemblyInitialize()] public static void AssemblyInit(TestContext context) { var dbss = new DatabaseSnapshot(...); dbss.CreateSnapshot(); } [AssemblyCleanup()] public static void AssemblyCleanup() { var dbss = new DatabaseSnapshot(...); dbss.RevertDatabase(); } } Now this all works, but my problem arise when I have a failing test or some exception. The AssemblyCleanup is of course not invoked, so how can I solve this problem? No matter what happens, the snapshot has to be restored. Is this possible?

  • Given a large set of vertices in a non-convex polygon, how can i find the edges?

    - by tommy chheng
    I have a set of vertices(called A) and I want to find all the border vertices such that this border vertices set is an outline of the shape. Many of the vertices in A are redundant because they are inside the shape, I want to get rid of these vertices. My question is similar to http://stackoverflow.com/questions/477867/best-algorithm-to-find-the-edges-polygon-of-vertices but i need it to work for a non-convex polygon case.

  • How to control docking order in C# WinForms

    - by Tommy
    As the title states, I'm looking for a way to control the order in which the items dock to the top of my control. I've played with the windows form designer, and i cant seem to find what the RightClick->Order->SendToFront is doing, because thats exactly what I want to happen. As far as I can get to happen, as I add my contents to my control, the newest contents is always at the top, and I'd like for the Newer contents to be on the bottom, and the oldest contents to be at the top. Summery: Is there an easy way in WinForms (C#), to control the order in which things dock to the sides of controls?

  • Checking existence of file types via extensions bash.

    - by Tommy
    Hi, I need to test if various file types exist in a directory. I've tried $ [ -f *.$fileext] where fileext is the file extension but that does not seem to work. Both of these methods work function checkext() { fileext=$1 ls *.$fileext>/dev/null 2>&1 if [ $? -eq 0 ] then echo "We have $fileext files!" else echo "We don't have any $fileext files!" fi } and function checkext2() { extention=$1 filescheck=(`ls *.$1`) len=${#filescheck[*]} if [ $len -gt 0 ] then echo "We have $extention files!" else if [ $len -eq 0 ] then echo "We don't have any $extention files!" else echo "Error" fi fi } The second method is less tidy as any ls error is shown so I prefer method 1. Could people please suggest any improvements, more elegant solutions e.t.c

  • .NET MVC Ajax Form - How do you hide it?

    - by Tommy
    Ok, everything is 'functionally' working with what I am attempting to accomplish and once again, I am sure this is something dumb, but I cannot figure out how to do this one thing. I have an edit form for an entity, lets say a car. This 'car' can have 0 - many passengers. So on my edit form, I have all the fields for the car, then a list view showing each passenger (partial). I also have a 'add new passenger' button that will render a new partial view that allows you to enter a passenger. This has a cancel link and an add button to submit an Ajax form. When you add a passenger, the passenger is automatically added to the list, but I need the enter passenger form to go away. I have tried using the onSuccess and onComplete functions to hide the div that the form is in, but both render just the partial view HTML elements (white screen, text) and not the partialView in the context of the entire page. Sources: 1) Main Edit View <script type="text/javascript"> Function hideForm(){ document.getElementById('newPassenger').style.display = 'none'; } </script> <h2>Edit</h2> <%-- The following line works around an ASP.NET compiler warning --%> <%= ""%> <%Html.RenderPartial("EditCar", Model)%> <h2>Passengers for this car</h2> <%=Ajax.ActionLink("Add New Passenger", "AddPassenger", New With {.ID = Model.carID}, New AjaxOptions With {.UpdateTargetId = "newPassenger", .InsertionMode = InsertionMode.Replace})%> <div id="newPassenger"></div> <div id="passengerList"> <%Html.RenderPartial("passengerList", Model.Passengers)%> </div> <div> <%= Html.ActionLink("Back to List", "Index") %> </div> 2) AddPassenger View. The cancel link below is an action that returns nothing, thus removing the information in the div. <% Using Ajax.BeginForm("AddPassengerToCar", New With {.id = ViewData("carID")}, New AjaxOptions With {.UpdateTargetId = "passengerList", .InsertionMode = InsertionMode.Replace})%> <%=Html.DropDownList("Passengers")%> <input type="submit" value="Add" /> <%=Ajax.ActionLink("Cancel", "CancelAddControl", _ New AjaxOptions With {.UpdateTargetId = "newPassenger", .InsertionMode = InsertionMode.Replace})%><% end using %>

  • Using R in Processing through rJava/JRI?

    - by tommy-o-dell
    Hi guys, Is it possible to run R in Processing through rJava/JRI? If I deployed a Processing app on the web, would the client need R on their system? I'm looking to create an interactive information dashboard that I can deploy on the web. It seems that Processing is probably my best bet for the interactive/web part of things. Unfortunately, it doesn't look like there are many math/stats functions built-in. And there aren't any libraries for plotting data either. I've been using R and gpplot2 for a few months and am thrilled (amazed) at how easily it manipulates and plots data. So I'm wondering now if can get the best of both worlds and run R through a Processing applet. From the JRI website: JRI is a Java/R Interface, which allows to run R inside Java applications as a single thread. Basically it loads R dynamic library into Java and provides a Java API to R functionality. It supports both simple calls to R functions and a full running REPL. In a sense JRI is the inverse of rJava and both can be combined (i.e. you can run R code inside JRI that calls back to the JVM via rJava). The JGR project makes the full use of both JRI and rJava to provide a full Java GUI for R. JRI uses native code, but it supports all platforms where Sun's Java (or compatible) is available, including Windows, Mac OS X, Sun and Linux (both 32-bit and 64-bit). Thanks for the advice :)

  • How to set initial window size in Java OpenGL

    - by tommy-susanto
    Hi guys... I just built a Java OpenGL application in Eclipse... and when i was trying to export the application using EclipseP5Exporter, it requires me to initialize the window size (not viewport size, a window may contain several viewports). I already googled some solutions in the net but I can't seem to get anything useful.. I've tried the method : "glutInitWindowSize(int width, int height);" but it seems to work only in C and python openGL. even if i append the glut before the method (glut.glutInitWindowSize()) eclipse doesn't recognize that method.. So if you guys have any suggestions please let me know... Thank you....

  • Execution time of ALTER COLUMN

    - by Tommy Jakobsen
    Having a table with 60 columns, and 200 rows. Altering a BIT column from NULL to NOT NULL, now has a running execution time of over 3 hours. Why is this taking so long? This is the query that I'm execution: ALTER TABLE tbl ALTER COLUMN col BIT NOT NULL Is there a faster way to do it, besides creating a new column, updating it with values from the old column, then dropping the old column and renaming the new one? This is on MS SQL Server 2005.
