  • Keyboard Mouse Problem

    - by Zachary K
    I just installed Ubuntu on my laptop (Core 2 Duo Sony Vaio) and am having a problem with the external keyboard and mouse. When I first logged in the left mouse button does not work, this can be solved by unplugging the external keyboard/mouse's USB connector and then plugging it back in again. But Then randomly other problems happen. (Shift gets stuck, keys don't work etc) The keyboard and mouse are a generic brand wireless (A4 Tech) that I got for cheap. Both work OK under windows so this is a major pain.

  • How To Install and Use ADB, the Android Debug Bridge Utility

    - by Chris Hoffman
    ADB, Android Debug Bridge, is a command-line utility included with Google’s Android SDK. ADB can control your device over USB from a computer, copy files back and forth, install and uninstall apps, run shell commands, and more. We’ve covered some other tricks that require ADB in the past, including backing up and restoring your smartphone or tablet and installing Android apps to your SD card by default. ADB is used for a variety of geeky Android tricks.

  • OpenID implementation - PHP, Javascript, MySQL

    - by Marc A.
    Hello, I've started doing some research on the technologies that I will need for my website. I'm trying to implement a really simple website with OpenID user registration. The website will store a block of text for each user. I imagine this means that I will need a database with: User ID Open ID url Data Having said that, I'm still having trouble deciding what I really need to do this. I know that I will need the following for the actual site: Javascript JQuery CSS But on the back end, I'm kind of lost at the moment. I've been looking at the OpenID-Selector, which is coded in Javascript. It seems like it's exactly what is used on this site. Will I actually need PHP? MySQL for the data and user registration? Thanks for the kickstart!

  • What are the things you can do to maximize your chances of hitting good programmers in the campus?

    - by Graviton
    I'm thinking about approaching my lecturers in my university for student recommendation for me to hire. So far the emails I sent are not very encouraging. The lecturers either coming back to me, saying that they couldn't get good students, or just ignore my mail. I tried to be as polite as I could in the email, so I think it's not etiquette issue that turn them off. Still, I plan to visit my campus. What are the things I can do to maximize your chances of hitting good programmers in the campus? Any experience you can share?

  • Should I get my masters in Game Design and Development or Computer Science?

    - by Christopher Stephenson
    I am a recent grad with a B.S. in IT while I didn't minor in Game Desgin and development, I took few classes in it. During my job search I have seen that most gaming companies seems to want someone that majored in C.S, mathematics, or physics. During my undergrad I never had to take physics nor did I learn much about data structures and algorithms. These seem to be really important when searching for a job in game development. So I am thinking about going back to school to get my masters in either CS, or GDD. The problem though is which one? I am really not looking to create my own games, I just want to work on games.

  • Calling all developers building ASP.NET applications

    - by Laila Lotfi
    We know that developers building desktop apps have to contend with memory management issues, and we’d like to learn more about the memory challenges ASP.NET developers are facing. To be more specific, we’re carrying out some exploratory research leading into the next phase of development on ANTS Memory Profiler, and our development team would love to speak to developers building ASP.NET applications. You don’t need to have ever used ANTS profiler – this will be a more general conversation about: - your current site architecture, and how you manage the memory requirements of your applications on your back-end servers and web services. - how you currently diagnose memory leaks and where you do this (production server, or during testing phase, or if you normally manage to get them all during the local development). - what specific memory problems you’ve experienced – if any. Of course, we’ll compensate you for your time with a $50 Amazon voucher (or equivalent in other currencies), and our development team’s undying gratitude. If you’d like to participate, please just drop me a line on [email protected].

  • When can I be sure a directed graph is acyclic?

    - by Daniel Scocco
    The definition for directed acyclic graph is this: "there is no way to start at some vertex v and follow a sequence of edges that eventually loops back to v again." So far so good, but I am trying to find some premises that will be simpler to test and that will also guarantee the graph is acyclic. I came up with those premises, but they are pretty basic so I am sure other people figured it out in the past (or they are incorrect). The problem is I couldn't find anything related on books/online, hence why I decided to post this question. Premise 1: If all vertices of the graph have an incoming edge, then the graph can't be acyclic. Is this correct? Premise 2: Assume the graph in question does have one vertex with no incoming edges. In this case, in order to have a cycle, at least one of the other vertices would need to have two or more incoming edges. Is this correct?

  • Unity launcher autohide leaves "ghost" behind?

    - by Hailwood
    In 12.04 I had the launcher set to autohide, which worked perfectly. However in 12.10 I am getting a strange "ghost" issue. Take this screenshot, with me having a maximised google chrome window, mousing over the back button. As well as this, I also get another ghosting issue when I have the panel set with an opacity, whereby whatever is in approximately the middle left of the screen gets mirrored up to to panel, but only when I move/switch to a window. But that one is not so annoying as the autohide bug, how can I fix that?

  • Alternative way of developing for ASP.NET to WebForms - Any problems with this?

    - by John
    So I have been developing in ASP.NET WebForms for some time now but often get annoyed with all the overhead (like ViewState and all the JavaScript it generates), and the way WebForms takes over a lot of the HTML generation. Sometimes I just want full control over the markup and produce efficient HTML of my own so I have been experimenting with what I like to call HtmlForms. Essentially this is using ASP.NET WebForms but without the form runat="server" tag. Without this tag, ASP.NET does not seem to add anything to the page at all. From some basic tests it seems that it runs well and you still have the ability to use code-behind pages, and many ASP.NET controls such as repeaters. Of course without the form runat="server" many controls won't work. A post at Enterprise Software Development lists the controls that do require the tag. From that list you will see that all of the form elements like TextBoxes, DropDownLists, RadioButtons, etc cannot be used. Instead you use normal HTML form controls. But how do you access these HTML controls from the code behind? Retrieving values on post back is easy, you just use Request.QueryString or Request.Form. But passing data to the control could be a little messy. Do you use a ASP.NET Literal control in the value field or do you use <%= value % in the markup page? I found it best to add runat="server" to my HTML controls and then you can access the control in your code-behind like this: ((HtmlInputText)txtName).Value = "blah"; Here's a example that shows what you can do with a textbox and drop down list: Default.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="NoForm.Default" %> <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="NoForm.Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form action="" method="post"> <label for="txtName">Name:</label> <input id="txtName" name="txtName" runat="server" /><br /> <label for="ddlState">State:</label> <select id="ddlState" name="ddlState" runat="server"> <option value=""></option> </select><br /> <input type="submit" value="Submit" /> </form> </body> </html> Default.aspx.cs using System; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; namespace NoForm { public partial class Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //Default values string name = string.Empty; string state = string.Empty; if (Request.RequestType == "POST") { //If form submitted (post back) name = Request.Form["txtName"]; state = Request.Form["ddlState"]; //Server side form validation would go here //and actions to process form and redirect } ((HtmlInputText)txtName).Value = name; ((HtmlSelect)ddlState).Items.Add(new ListItem("ACT")); ((HtmlSelect)ddlState).Items.Add(new ListItem("NSW")); ((HtmlSelect)ddlState).Items.Add(new ListItem("NT")); ((HtmlSelect)ddlState).Items.Add(new ListItem("QLD")); ((HtmlSelect)ddlState).Items.Add(new ListItem("SA")); ((HtmlSelect)ddlState).Items.Add(new ListItem("TAS")); ((HtmlSelect)ddlState).Items.Add(new ListItem("VIC")); ((HtmlSelect)ddlState).Items.Add(new ListItem("WA")); if (((HtmlSelect)ddlState).Items.FindByValue(state) != null) ((HtmlSelect)ddlState).Value = state; } } } As you can see, you have similar functionality to ASP.NET server controls but more control over the final markup, and less overhead like ViewState and all the JavaScript ASP.NET adds. Interestingly you can also use HttpPostedFile to handle file uploads using your own input type="file" control (and necessary form enctype="multipart/form-data"). So my question is can you see any problems with this method, and any thoughts on it's usefulness? I have further details and tests on my blog.

  • Auto-Invoke Update Manager to update everything and shutdown after system idle for x minutes?

    - by unknownthreat
    I have Ubuntu 10.10 installed on a machine for my parents. The thing is they never request updates from Update Manager even the manager itself prompted them so. Moreover, when they are done with whatever they are doing on Ubuntu, they always leave the computer on. And I always have to come back and shut the machine down. Sometimes, the computer even sit idle for hours. So I want to know whether this is possible in Ubuntu. I am thinking of a script that will be activated after the machine is idle for x minutes. When x minutes have elapsed, Update Manager will automatically update everything listed. (I recall that you need the admin password for this, so is there a workaround?) After all the updates are done, the machine will automatically shutdown. Is this possible?

  • The entire content of my Wordpress page has disappeared

    - by John Catterfeld
    I have a blog installed on my site using Wordpress. Last week I upgraded Wordpress from 2.6 to 3.0.4 (I had to do this manually). All went well, or so I thought, but I have just noticed that the content of an existing page has vanished. The page URL still works, but all content has disappeared - doctype, html tags, body tags, everything. Please note, this is specific to pages - posts are still displaying fine. I have since created a brand new page which does not display the content either. Things I have tried include Switching to a freshly installed theme Deactivating all plugins Setting the problem page to draft, and back again Deleting the .htaccess file I suspect it's a database problem and have contacted my hosting company who have said the only thing they can do is restore the DB from a backup, but that I should consider it a last resort. Does anyone have any further ideas what to try?

  • Hide all normal windows shortcut is not working in Ubuntu 13.10

    - by Vladislav Ivanishin
    Hide all normal windows shortcut is not working. It is currently set to Alt+Ctrl+D. And changing the shortcut doesn't help (tried Super+D, Alt+Esc). However other shortcuts work fine (even from the same Navigation tab). I guess the question is a duplicate of this which is unanswered. Update: It works exactly one time after reboot. I can minimize windows and even bring them back using the combination but only once. Also switching keyboard layout shortcut stopped working, but as I can see it's a known bug.

  • How to close lid without triggering standby one time only

    - by Ian Mackinnon
    Related: How can I tell Ubuntu to do nothing when I close my laptop lid? I have my laptop set to activate standby when I close the lid. I want to keep this as the default for both battery and AC power. But occasionally I want to close the lid without triggering standby (eg. while just listening to audio). Is there someway I can tell Ubuntu, "I'm going to close the lid now. Don't stand by this time", without altering the defaults (because I almost always forget to change them back).

  • How can I reduce the number of spammers registering with my phpBB site?

    - by Jayapal Chandran
    I have a site which runs phpBB, on this site I have enabled user authentication through email when registering enabled captcha However I still get spam users every 20 to 30 minutes. Is there anything I can do to prevent this with the ucp.php file? I have already loaded a large list of IP addresses yet there are spam users registering all the time. One thing I can do is I can check the bounce mail to find the username and can pipe bounced mails to a php script and immediately delete that user, but I have not got any bounce back from hotmail or some other email clients. So this way it will catch hold of a certain percent of spam users but there are still a huge amount of users spamming. What else can I do to prevent spammers abusing my phpBB site?

  • Unity Desktop not loading and ccsm method not working

    - by slimy-spork
    I installed Ubuntu 13.04 x86_64 on my HP Pavillion DV7-6c60us. It installs fine and works until I update. I run the software updater and reboot as it requests after. When my computer comes back on I get the desktop background but the rest of the Unity desktop doesn't load. I've tried the ccsm method and re-enabling but it just de-enables itself. I've also tried installing the gnome desktop but that does nothing for me either. I really want to switch to Ubuntu but this is causing issues. P.S. I've also tried using 12.10 and 12.04 with no dice.

  • statistics for checking imported data?

    - by user1936
    I'm working on a data migration of several hundred nodes from a Drupal 6 to a Drupal 7 site. I've got the data exported to the new site and I want to check it. Harkening back to my statistics classes, I recall that there is some way to figure out a random number of nodes to check to give me some percentage of confidence that the whole process was correct. Can anyone enlighten me as to this practical application of statistics? For any given number of units, how big must the sample be to have a given confidence interval?

  • Minecraft Fullscreen not working

    - by Straemer
    I upgraded to Quantal recently, and Minecraft seems to not want to run in fullscreen. When I go to fullscreen it, the screen will go black for a second, as if it was about to go fullscreen normally, but then it just restores back into its window. So far I have tried: using different JREs (I've tried openjdk 6 and 7, as well as oracle7). Oracle's jre wouldn't even run Minecraft (I just got a black screen after logging in) switching graphics drivers (tried nvidia-current, nvidia-current-updates, and xserver-xorg-video-nouveau) updating minecraft bin files updating lwjgl libraries separately from the lwjgl site None of this seemed to work at all. I am running Minecraft with the command java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame Graphics card is GeForce 9500 GS/PCIe/SSE2. Everything was working fine a few days ago when I was on 12.04.

  • Why does Live-USB boot freeze at the moving dots?

    - by Caleb
    I am currently trying to boot into Ubuntu 12.04 x86 using a USB. I used Untetbootin to do all that boot crap and what not. But for some reason Ubuntu wont load pass that screen with the dots and the purple background. What happens is the dots all light up once, then they go back to white then they all light up at the same time and then it just gets stuck there. Ive even tried using an x64 copy (since my CPU supports it) but have no luck with that either. Ive even tried different DISTRIBUTIONS of Linux and all have failed with loading. Please help

  • Lenovo e530 no wireless Ubuntu 13.04

    For some reason my wireless will not work on my Lenovo e530. I am dual booting ubuntu and windows 8 and my wireless works in windows. I saw online that I should run rfkill. I did that but only bluetooth shows up. There is no difference when I press the wireless fn key either, but it does block bluetooth (as it should). I'm really wanting to get into Ubuntu but this is holding me back. To clarify the wireless device does not show at all after running rfkill.

  • Arabic disappeared after 12.04 upgrade!

    - by Aboubakr
    Well, I was amongst the 12.04 Beta upgraders, and since then I've lost the ability to write in Arabic, and I've been using Ubuntu since 2008 as an only OS without any issues, and been upgrading since then as well, except on this machine, which received one upgrade from 11.10 to 12.04 and it got messed up. I've added Arabic like usual, but it doesn't change with the keyboard's short-cut, and when I do it manually with the Mouse, then it just doesn't work, and it keeps writing in English instead. I've tried to install some iBus things, and added Arabic-kbd (m17n) but it still remains messy, let alone not having the same layout, and all I want is to get to NORMAL. So, please, is there any way to reset or initialize these keyboard related settings, so I can get back to normal and stop using the Mac just to type in Arabic, or so often using XP over Vbox? And please, no Re-install option! I just can't backup all my work right now, and there are a lot of tasks waiting for me to get them done. Thanks for any kind of support :)

  • How to stop getting too focused on a train of thought when programming?

    - by LDM91
    I often find myself getting too focused on a train of thought when programming, which results in me having what I guess could be described as "tunnel vision". As a result of this I miss important details/clues, which means I waste a fair amount of time before finally deciding the path I'm taking to solve the task is wrong. Afterwards, I take a step back which almost always results in me discovering what I've missed in a lot less time.. It's becoming really frustrating as it feels like I'm wasting a lot of time and effort, so I was wondering if anyone else had experienced similar issues, and had some suggestions to stop going down dead ends and programming "blindly" as it were!
