  • GUI is not displayed anymore

    - by mdobrinin
    I am running 12.04 LTS on a VM. I encountered a problem with the screen being black and the familiar orange background showing for a fraction of a second when clicking or resizing the screen. I had to shutdown the machine and now I have no GUI. I only get a black command-line interface. As some other posts suggest, I attempted: sudo service lightdm restart This doesn't work for me because it gets stuck at this point: Skipping profile in /etc/apparmor.d/disable: user.bin.firefox Skipping profile in /etc/apparmor.d/disable: user.sbin.rsyslogd * Starting AppArmor profiles [ OK ] Any ideas?

  • Windows user moving to Ubuntu 12.04. Where are the system tools, or equivalents?

    - by Big Endian
    I am a Windows user who has begun experimenting with Ubuntu. Ubuntu seems great, but for all the things it seems like I CAN'T do. How do I get to advanced administration stuff, like the list of drivers, all of the installed software, and something equivalent to Windows' Device Manager. I always heard that Linux was supposed to be very raw, and you had to have lots of computer experience to make it work. This seems just the opposite. Ubuntu seems very modern and user friendly, better in some regards than any operating system I have seen. Unfortunately, I can't find any of the guts of this system beneath all of the user friendly frosting... gunk... crap... stuff. I'm reminded more and more of an Apple computer (except Linux is more affordable :). So how do I peel back this layer and start using the computer? A solution other than installing Gnome 3 would be appreciated.

  • Getting State of Modifier Keys Compact Framework

I want to be able to determine if the following keys are pressed or locked: Shift CTRL ALT and for the Psion Teklogix machines Orange Blue Although I may be able to work this out, if I can determine the others. I want to create my own on-screen indicator panel and want to poll the keys, not using events. Thanks Colin

  • Fixing LOD gaps, T-junctions

    - by Jaka Jancar
    I'm creating a heightmap renderer. One of the examples for solving gaps when doing LOD I found is this: (from Game Programming Gems 2 - Greg Snook - Simplified Terrain using Interlocking Tiles) Wouldn't this still produce a gap, if the three vertices encircled with red were not co-linear? Shouldn't the middle triangle be split into two, as I marked with the orange line? Am I misunderstanding the problem, or is there a mistake in the example?

  • Any Naive Bayesian Classifier in python?

    - by asldkncvas
    Dear Everyone I have tried the Orange Framework for Naive Bayesian classification. The methods are extremely unintuitive, and the documentation is extremely unorganized. Does anyone here have another framework to recommend? I use mostly NaiveBayesian for now. I was thinking of using nltk's NaiveClassification but then they don't think they can handle continuous variables. What are my options?

    - by skb
    I would like to have fuzzy looking border around my Canvas control. Basically, I am creating a Print Preview screen, and I want it to look almost exactly like the one in Word 2010. In this, there is a thin gray line, a thin orange line and then a fuzzy gradient around the outside of the page. Check it out and you will see what I mean. Can anyone tell me how I can do this with my Canvas control?

  • How to set clickable and highlightable a ViewStub?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • CSS to Replace Table Layout for Forms

    - by Erick
    I've looked at other questions and am unable to find the solution to this. Consider this image: I want to wrap divs and stack them vertically. The GREEN div would be a wrapper on a line. The BLUE div would contain an html label and maybe icon for a tooltip. The ORANGE div would contain some sort of entry (input, select, textarea). Several of these would be stacked vertically to make up a form. I am doing this now, but I have to specify a height for the container div and that really needs to change depending on the content - considering any entry could land there. Images and other stuff could land here, as well. I have a width set on the BLUE div and the ORANGE is float:left. How can I get rid of the height on divs and let that be determined by content? Is there a better way? Changing all to something else would be difficult and would prefer a way to style all elements or something. The code I'm using is like: <div class=EntLine> <div class=EntLbl> <label for="Name">Name</label> </div> <div class=EntFld> <input type=text id="Name" /> </div> </div> The CSS looks like: .EntLine { height: 20px; position: relative; margin-top: 2px; text-align: left; white-space: nowrap; } .EntLbl { float: left; width: 120px; padding: 3px 0px 0px 3px; min-width: 120px; max-width: 120px; vertical-align: text-top; } .EntFld { float: left; height: 20px; padding: 0px; width: 200px; } Thanks!

  • Getting XML data from a external page and parsing it with PHP

    - by James P
    I'm trying to create a database of World of Warcraft gems. If I go to this page: http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items And go to View Source in Firefox, I see a tonne of XML data which is exactly what I want. I wrote up this quick script to try and parse some of it: <?php $gemUrls = array( 'Blue' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=blue&searchType=items', 'Red' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=red&searchType=items', 'Yellow' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=yellow&searchType=items', 'Meta' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=meta&searchType=items', 'Green' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=green&searchType=items', 'Orange' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=orange&searchType=items', 'Purple' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items', 'Prismatic' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items' ); // Get blue gems $blueGems = file_get_contents($gemUrls['Blue']); $xml = new SimpleXMLElement($blueGems); echo $xml->items[0]->item; ?> But I get a load of errors like this: Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: Entity: line 20: parser error : xmlParseEntityRef: no name in C:\xampp\htdocs\WoW\index.php on line 19 Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: if(Browser.iphone && Number(getcookie2("mobIntPageVisits")) < 3 && getcookie2( in C:\xampp\htdocs\WoW\index.php on line 19 I'm not sure what's wrong. I think file_get_contents() is bringing back data that isn't XML, maybe some Javascript files judging by the iPhone parts in the errors. Is there any way to just get back the XML from that page? Without any HTML or anything? Thanks :)

    - by Mike
    I'm trying to sort a GLibc hash table by id that looks something like: key - id { "Red", 2, "BLue", 4, "Yellow", 5, "Orange", 8 } I'm just not sure how to approach this because GLibc does not have a sort method. I was thinking to use qsort or GCompareFunc Any ideas will be appreciate it!

  • How to limit results in a SharePoint XSL query

    - by David
    Hello all, I am creating a SharePoint site that we will use to report issues with trucks used in our business. Linked to the list I have created will be a page that will display an overview of the trucks and a little truck icon will show the trucks current status. Green and the truck is okay (no open issues), Red and the truck have an open issue with status "Undrivable", Orange and there is two issues open that requires the user to look further into the truck before using it and finally a Gray truck for when there is a new issue created that has not been looked into (not sure if it is drivable or not). I have managed to create the "Dashboard" and with my limit XSL/XPATH knowledge been able to add a truck and replicate the description above but... in my test I have created 4 issues, for example if three of them are changed to status Closed and one left to Undrivable I will get four icons on the page, three with Green trucks and the last one Red. So in theory it works but I obviously only want to see the last truck, one truck. I am not interested in seeing the others. <xsl:template name="dvt_1.rowview"> <xsl:variable name="CountReport" select="count(/dsQueryResponse/Rows/Row[@Highloader='GGEU12' and @Status!='Closed'])" /> <xsl:variable name="MoreThan" select="$CountReport &gt; 1" /> <xsl:variable name="NoReports" select="$CountReport = 0" /> <xsl:variable name="Closed" select=" @Highloader='GGEU12' and @Status='Closed'" /> <xsl:choose> <xsl:when test="$MoreThan"> <div class="ms-vb"><img title='More than one report exist!' border='0' alt='In Progress' src='highloader/Library/hl-orange.png' /></div> </xsl:when> <xsl:otherwise> <div class="ms-vb"><xsl:value-of disable-output-escaping="yes" select="@Icon" /></div> </xsl:otherwise> </xsl:choose> </xsl:template> My hope is that someone with slightly more knowledge can find the last piece of the puzzle for me! Thanks for reading and asking questions to fill any gap I left above. David

  • T-SQL: Omit/Ignore repetitive data from a specific column

    - by Dsyfa
    Hi, For my question lets consider the following sample table data: ProductID    ProductName    Price   Category 1                Apple                 5.00       Fruits 2                Apple                 5.00       Food 3                Orange               3.00       Fruits 4                Banana                 2.00       Fruits I need a query which will result in the following data set: ProductID    ProductName    Price   Category 1                Apple                 5.00       Fruits 3                Orange               3.00       Fruits 4                Banana                 2.00       Fruits As you can see ProductID 2 has been omitted/ignored because Apple is already present in the result i.e. each product must appear only once irrespective of Category or Price. Thanks

  • Coding Conventions - Naming Enums

    - by Walter White
    Hi all, Is there a document describing how to name enumerations? My preference is that an enum is a type. So, for instance, you have an enum Fruit{Apple,Orange,Banana,Pear, ... } NetworkConnectionType{LAN,Data_3g,Data_4g, ... } I am opposed to naming it: FruitEnum NetworkConnectionTypeEnum I understand it is easy to pick off which files are enums, but then you would also have: NetworkConnectionClass FruitClass Also, is there a good document describing the same for constants, where to declare them, etc.? Walter
