• Ubuntu 12.4.1 failing in vm both Vbox and Vmware on new HP Envy 4t-1000

  - by Chas

  Brand new to Linux, getting frustrated trying to get an environment up with Ubuntu. My primary goal is to learn Linux and Apache/PHP development. I need to keep my Windows OS as main on my machine for work, so i'm trying to virtualize Ubuntu 12.4.1 without luck (many attempts). I have a new HP Envy 4t-1000 with 16gb ram, and 32 gb ssd caching with 500gb spindle hard drive. Graphics card is an Intel HD 3000 with AMD Radeon 7670M. With installing Ubuntu desktop in VBox, I'm getting this result: https://forums.virtualbox.org/viewtopic.php?f=6&t=51939 With VMware workstation 7 (patched), I complete the install of Ubuntu, it reboots, purple desktop briefly flashes then it drops to command line. I bought a beginning Ubuntu book, and it recommends trying to manually configure graphics if this happens. So I tried doing a safe boot holding shift - I get to the first screen (GRUB) loads fine, and I choose recovery mode. After choosing the recovery mode, I get the recovery mode options, and can arrow down to what the book suggests 'Run in fail safe graphic mode.' Once I select this option, I get a black screen with a large white dialogue box, at the top it says "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." Then there is an ok button way down at the bottom. When I select 'ok' I get a menu for a few options, book recommended 'reconfigure graphics.' When I try this, I get a menu of two options: 1) "Use generic (default) configuration or 2) use backup. I've tried both options several times, hitting ok just refreshes screen and nothing more. Rebooting at this point just goes back to command line as before. I don't know what to do at this point, I've spent too many hours this weekend trying in both VBox and VMware to get Ubuntu going. Isn't there like a very basic graphic display or something I can use to at least get into the desktop? I explored the GRUB some more, and tried to look at the startup and xserver logs - both are blank. No help there I guess? When I try to choose 'Edit the configuration file, then 'ok' screen just refreshes on same menu options, nothing happens. thx for any advice. I really need to focus on learning Linux, Apache and PHP, so perhaps Ubuntu just won't work on my hardware? Any other suggestions? I will need to virtualize - THANKS for any help/advice.

• Set and Verify the Retention Value for Change Data Capture

  - by AllenMWhite

  Last summer I set up Change Data Capture for a client to track changes to their application database to apply those changes to their data warehouse. The client had some issues a short while back and felt they needed to increase the retention period from the default 3 days to 5 days. I ran this query to make that change: sp_cdc_change_job @job_type='cleanup', @retention=7200 The value 7200 represents the number of minutes in a period of 5 days. All was well, but they recently asked how they can verify...(read more)

• Make sudoers work with only certain parameter?

  - by Evan

  I'm trying to make my sudoers file allow a user to adjust the backlight without having to enter in the password. This is what I have: # User alias specification Cmnd_Alias ADJBL = /usr/bin/su -c "echo 150 >/sys/class/backlight/intel_backlight/brightness" # For our user.. ouruser HOME=(root) NOPASSWD:ADJBL .. but it doesn't seem to be working, I still get prompted for the password when I try and run that command with sudo. Apparently there is something I'm missing here, any ideas?

• What is the difference between the 'sudo' and 'admin' group?

  - by ændrük

  I noticed that two groups are granted similar-looking permissions in /etc/sudoers: # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL My user account with "Administer the system" privileges is in the admin group, and there don't appear to be any users in the sudo group. What are these two groups for?

• Running CLOC (count lines of code) on Windows...or alternative

  - by Chelonian

  I'm trying to use CLOC on Windows (XP) to count lines of code, and I can't get it to work. I downloaded the latest Win installer for CLOC 1.5.6, ran it (which caused a "DOS" window to open, scroll with text rapidly, then close before I could read anything) and then wrote cloc at the cmd prompt...and Windows doesn't recognize it as a command. Or if there is another easy-to-use lines of code counter that one could recommend (that runs on Windows), I'd be happy to try that.

• How to use multiple search keys?

  - by user32565

  I have a database wherein the files are named abcd100.00b, abcd101.00b, etc. I need a code where when the user enters abcd separate then 100 to 110, all the files with the name abcd and in the range 100 to 110 should get displayed now the following code can display only the first four characters. How do I implement this? <?php //capture search term and remove spaces at its both ends if the is any $searchTerm = trim($_GET['keyname']) ; //check whether the name parsed is empty if($searchTerm == "rinex_file") { echo "Enter name you are searching for."; exit(); } if($searchTerm == "rinex_file") { echo "Enter name you are searching for."; exit(); } //database connection info $host = "localhost"; //server $db = "rinex"; //database name $user = "m"; //dabases user name $pwd = "c"; //password //connecting to server and creating link to database $link = mysqli_connect($host, $user, $pwd, $db); //MYSQL search statement $query = "SELECT * FROM rinexo WHERE rinex_file LIKE '%$searchTerm%'"; $results = mysqli_query($link, $query) ; /* check whethere there were matching records in the table by counting the number of results returned */ if(mysqli_num_rows($results) >= 1){ echo '<table border="1"> <tr> <th>rinex version</th> <th>program</th> <th>date</th> <th>maker name</th> <th>maker number</th> <th>observer</th> <th>agency</th> <th>position_X_Y_Z</th> </tr>'; while($row = mysqli_fetch_array($results)){ echo '<tr> <td>'.$row['rinex_version'].'</td> <td>'.$row['pgm'].'</td> <td>'.$row['date'].'</td> <td>'.$row['marker_name'].'</td> <td>'.$row['marker_no'].'</td> <td>'.$row['observer'].'</td> <td>'.$row['agency'].'</td> <td>'.$row['position_X_Y_Z'].'</td> </tr>'; } echo '</table>'; }else{ echo "There was no matching record for the name " . $searchTerm; }

• Disable Dash Home Shortcut in 12.04

  - by kunigami

  I'm using Ubuntu 12.04 in VirtualBox on a MacBook. The current shortcut for the dash home launcher is the Command key (Super). I'm trying to disable it. First, this option is not present in the shortcuts preferences. I have already tried: Changing it through gconf-editor Changing it through ccsm Even though when I press Super or Super+F it still launches the dash home. Any ideas on what I can still try?

• How does the fstab 'defaults' option work? Is relatime recommended?

  - by hushs

  I know the fstab defaults option means this: rw,suid,dev,exec,auto,nouser,async. But what if I want to add one more option, for example relatime, should I still add defaults too or they are applied anyway? Is it needed to add at least one option? Some examples: 1. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults 0 2 2. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 0 2 3. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults,relatime 0 2 4. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 relatime 0 2 Is the (2) correct(no option at all)? Are the (1) and (2) the same? Are the (3) and (4) the same? Furthermore, I read in the Ubuntu Community Documentation that in Ubuntu 8.04 relatime was used as default for linux native file systems. Is it still true for 12.04? If yes, then why do I see this if I use the mount command: /dev/sda2 on / type ext4 (rw,errors=remount-ro) If no, why not? It isn't recommended to use relatime now? I just wanted to apply it to my non system partitions, it is a good idea? EDIT: I found an other command to list the mounted partitions and their options: cat /proc/mounts This is the result of a partition mounted with the defaults option in fstab: /dev/sdb2 /media/adat ext3 rw,relatime,errors=continue,barrier=1,data=ordered 0 0 This is the output of mount for the same partition: /dev/sdb2 on /media/adat type ext3 (rw) And here is both result if the same partition mounted from Nautilus as a non-root user: /dev/sdb2 /media/adat ext3 rw,nosuid,nodev,relatime,errors=continue,barrier=1,data=ordered 0 0 /dev/sdb2 on /media/adat type ext3 (rw,nosuid,nodev,uhelper=udisks) So it looks like relatime is used if we mount an ext partition in 12.04. So it is unneeded to add it manually. So my problem is broadly solved. But I still can't see why the options that should be in the defaults are not listed even with the cat /proc/mounts. Maybe there is a third and even better method to list the partition mount options :)

• Map caps-lock key to middle mouse click

  - by Stefano Palazzo

  Since I rarely use caps-lock, I'd like to map the key to a middle mouse click instead. I would also like to map Alt+Caps Lock to the original function of the caps lock key, should I ever need it. I can map any keyboard shortcut to xdotool click 2, but the Gnome Keyboard Shortcuts dialog won't let me assign a command to the caps-lock key, even with modifiers. I know this is a bit of a strange undertaking; How would I go about doing it?

• Play Framework Plugin for NetBeans IDE

  - by Geertjan

  The start of minimal support for the Play Framework in NetBeans IDE 7.3 Beta would constitute (1) recognizing Play projects, (2) an action to run a Play project, and (3) classpath support. Well, most of that I've created already, as can be seen, e.g., below you can see logical views in the Projects window for Play projects (i.e., I can open all the samples that come with the Play distribution). Right-clicking a Play project lets you run it and, if the embedded browser is selected in the Options window, you can see the result in the IDE. Make a change to your code and refresh the browser, which immediately shows you your changes: What needs to be done, among other things: A wizard for creating new Play projects, i.e., it would use the Play command line to create the application and then open it in the IDE. Integration of everything available on the Play command line. Maybe the logical view, i.e., what is shown in the Projects window, should be changed. Right now, only the folders "app" and "test" are shown there, with everything else accessible in the Files window, as can be seen in the screenshot above. More work on the classpath, i.e., I've hardcoded a few things just to get things to work correctly. Options window extension to register the Play executable, instead of the current hardcoded solution. Scala integrations, i.e., investigate if/how the NetBeans Scala plugin is helpful and, if not, create different/additional solutions. E.g., the HTML templates are partly in Scala, i.e., need to embed Scala support into HTML. Hyperlinking in the "routes" file, as well as special support for the "application.conf" file. Anyone interested, especially if you're a Play fan (a "playboy"?), in joining me in working on this NetBeans plugin? I'll be uploading the sources to a java.net repository soon. It will be here, once it has been made publicly accessible: http://java.net/projects/nbplay/sources/nbplay Kind of cool detail is that the NetBeans plugin is based on Maven, which means that you could use any Maven-supporting IDE to work on this plugin.

• Building an ASP.Net 4.5 Web forms application - part 3

  - by nikolaosk

  ?his is the third post in a series of posts on how to design and implement an ASP.Net 4.5 Web Forms store that sells posters on line.Make sure you read the first and second post in the series.In this new post I will keep making some minor changes in the Markup,CSS and Master page but there is no point in presenting them here. They are just minor changes to reflect the content and layout I want my site to have. What I need to do now is to add some more pages and start displaying properly data from my database.Having said that I will show you how to add more pages to the web application and present data.1) Launch Visual Studio and open your solution where your project lives2) Add a new web form item on the project.Make sure you include the Master Page.Name it PosterList.aspxHave a look at the picture below 3) In Site.Master add the following link to the master page so the user can navigate to it.You should only add the line in bold     <nav>                    <ul id="menu">                        <li><a runat="server" href="~/">Home</a></li>                        <li><a runat="server" href="~/About.aspx">About</a></li>                        <li><a runat="server" href="~/Contact.aspx">Contact</a></li>                          <li><a href="http://weblogs.asp.net/PosterList.aspx">Posters</a></li>                    </ul>                </nav> 4) Now we need to display categories from the database. We will use a ListView web server control.Inside the <div id="body"> add the following code. <section id="postercat">       <asp:ListView ID="categoryList"                          ItemType="PostersOnLine.DAL.PosterCategory"                         runat="server"                        SelectMethod="GetPosterCategories" >                        <ItemTemplate>                                                    <a href="http://weblogs.asp.net/PosterList.aspx?id=<%#: Item.PosterCategoryID %>">                            <%#: Item.PosterCategoryName %>                            </a>                            </b>                        </ItemTemplate>                        <ItemSeparatorTemplate> ----- </ItemSeparatorTemplate>                    </asp:ListView>             </section>        Let me explain what the code does.We have the ListView control that displays each poster category's name.It also includes a link to the PosterList.aspx page with a query-string value containing the ID of the category. We set the ItemType property in the ListView to the PosterCategory entity .We set the SelectMethod property to a method GetPosterCategories. Now we can use the data-binding expression Item (<%#: %>) that is available within the ItemTemplate . 5) Now we must write the GetPosterCategories method. In the Site.Master.cs file add the following code.This is just a simple function that returns the poster categories.        public IQueryable<PosterCategory> GetPosterCategories()        {            PosterContext ctx = new PosterContext();            IQueryable<PosterCategory> query = ctx.PosterCategories;            return query;        } 6) I just changed a few things in the Site.css file to style the new <section> HTML element that includes the ListView control.#postercat {  text-align: center; background-color: #85C465;}     7) Build and run your application. Everything should compile now. Have a look at the picture below.The links (poster categories) appear.?he ListView control when is called during the page lifecycle calls the GetPosterCategories() method.The method is executed and returns the poster categories that are bound to the control.  When I click on any of the poster category links, the PosterList.aspx page will show up with the appropriate Id that is the PosterCategoryID.Have a look at the picture below  We will add more data-enabled controls in the next post in the PosterList.aspx page. Some people are complaining the posts are too long so I will keep them short. Hope it helps!!!

  When the web was at infant stage, the search engine field was at nascent stage too and not dominated by any search engines as today. You could easily count the names of search engines, for example AltaVista, Excite, Lycos, Infoseek, HotBot and WebCrawler. The drawback of the absence of a good search engine was that you had to submit a query to all the search engines and hope for best.

• What are the advantages of storing xml in a relational database?

  - by Chris

  I was poking around the AdventureWorks database today and I noticed that a number of tables (HumanResources.JobCandidate and Sales.Individual for example) have a column which is storing xml data. What I would to know is, what is the advantage of storing basically a database table row's worth of data in another table's column? Doesn't this make it difficult to query off of this information? Or is the assumption that the data won't need to be queried and just needs to be stored?

• Unable to boot into 11.10 in normal (get a black screen) OR recovery (get just a flashing cursor, no cli)

  - by user1092284

  Okay, so I had a dual boot of Tango Studio (based on Ubuntu 10.04) and Windows XP. Yesterday I downloaded the .iso for Ubuntu 11.10 and attempted to install from a USB (my BIOS won't normally boot from USB but I had PLOP boot manager on a CD). I booted up Ubuntu from the USB and then from there formatted the partition with Tango on and installed Ubuntu 11.10. On booting up I came into Grub rescue mode. So I booted up from the USB again and used boot-repair to reinstall Grub. After this I would see the normal Grub menu, but on choosing Ubuntu I would come to a black screen. On choosing recovery mode it would begin starting normally with no obvious errors but instead of coming to a cli I would just get a blank screen with a flashing cursor on the top left, not accepting any input. I have since reformatted and reinstalled from a CD rather than USB and had the exact same problem. I used boot-repair again and the result is the same. Output of the most recent boot-repair is at http://paste.ubuntu.com/869805/ I have also tried editing the ubuntu grub entry and replacing quiet with text nomodeset as I saw in an answer to another question. This got me a bit further - I saw the purple ubuntu loading screen but still came to a blank screen after that. Anyway, in most of the other questions in which that is brought up the user is still able to boot into recovery, while I am not. Can anyone help? Thanks in advance, let me know if there's any more info I need to provide! EDIT FOR MORE INFO: I read something saying it's quiet splash that should be replaced with nomodeset. Earlier I had left splash in the line. So i tried it this way and it froze after displaying the following text: fsck from util-linux 2.19.1 mountall: Plymouth command failed mountall: Disconnected from Plymouth /dev/sda5:clean, 139359/1741488 files, 745830/6961125 blocks From a bit of googling it doesn't look like plymouth is essential, but I've checked and I do have the most current versions of mountall and plymouth installed so I don't know why there's a problem EDIT FOR MORE INFO AGAIN: I used dkpg --reconfigure plymouth cause I saw it mentioned in another forum and it still says plymouth command failed on boot

  I'm trying to use the Awesome window manager with GNOME, i.e. running gnome-session --session=ubuntu on login, and it works great for the most part, except for the fact that the notification area/systray is missing a battery indicator.
