• Compiz and Clearlooks window border breaks active/inactive title bars

  - by jimbo1qaz

  When I turn on Compiz with the Compiz tray switcher and I use Clearlooks, Dust Sand, or possibly any title bar style that normally has window icons on right, some window title bars will not change. Instead, they stay selected or unselected randomly. Some windows, like Ubuntu Software Center and CCSM are unaffected. This problem only happens with GTK window manager. I am using the Malteworld compiz ppa for Emerald. The problem does not happen with plain Metacity, or a title bar style that normally has close button on right. Edit: It still happens with Emerald. Reinstalled with upgrade option (yeah, 11.04 to 11.04) and still same problem. So maybe faulty package?

• Best practice Java - String array constant and indexing it

  - by Pramod

  For string constants its usual to use a class with final String values. But whats the best practice for storing string array. I want to store different categories in a constant array and everytime a category has been selected, I want to know which category it belongs to and process based on that. Addition : To make it more clear, I have a categories A,B,C,D,E which is a constant array. Whenever a user clicks one of the items(button will have those texts) I should know which item was clicked and do processing on that. I can define an enum(say cat) and everytime do if clickedItem == cat.A .... else if clickedItem = cat.B .... else if .... or even register listeners for each item seperately. But I wanted to know the best practice for doing handling these kind of problems.

• Uninstalling GRUB from MacBook Air

  - by James Brooke

  So... I have a MacBook Air and I recently tried to install Ubuntu on my external HD. I booted Ubuntu from a flash drive and everything had gone fine. I turned off my computer and when I turned it on again I got a message of error and a "grub rescue" line to enter some code. I rebooted holding the "option" key and I selected the Mac partition and everything is fine with my system, but every time I start my system and I don't hold the "option" key, I get the same error and the grub rescue message. I just want things to go back to normal, as they were before I installed Ubuntu on my external HD (which, btw, presented a message that said there was no boot loader). What do I do?

• How to add sitemap of a blogger blog to Google webmaster tools?

  - by Chankey Pathak

  I have two blogs. Let's say http://name.blogspot.com/ and the other one is http://name2.blogspot.com/ For blog 1: While submitting sitemap to Google webmaster tool I selected the option and then added rss.xml at last. (http://name.blogspot.com/rss.xml) Sitemap added successfully. For blog 2: I followed the same procedure but it didn't work. Then I tried to open the url (http://name.blogspot.com/rss.xml). The url was showing the atom feeds. I tried same with the other blog but that url is redirecting to the feedburner feeds. I think this is the reason why the other blog's sitemap is not getting submitted. Help me with it.

• Ubuntu boot is slower than Windows 7

  - by Alex Bixel

  One of the reasons I installed Ubuntu (Wubi installer) was for a supposedly quick boot time. My boot time with Windows 7 is about 20-25 seconds, while my boot with Ubuntu is 30-40. I judged the boot times from the time after I selected the operating system on the initial selection menu and the grub menu, respectively. This is even after following all sorts of online guides to improve it. I've done driver profiling (and yes, I remembered to remove the "profile" edit in the grub file afterwards), I've cut a fair few startup programs out, and I've installed the preload package. But I'm still getting startup rates phenomenally slower than Windows 7. Any help here?

• mismatch of version of libkdcraw20 and libkdcraw-data

  - by naveen jankar

  I'm using Ubuntu 12.04 LTS. When I'm installlin digiKam, I'm getting a mismatch in the versions of libkdcraw20 and libkdcraw-data wanted by it and that available in the repositories. It wants version 4.8.5-0ubuntu0.2 (or in other words that is the latest version according to synaptic) but the available one is 4.8.5-0ubuntu0.3 in both cases. Is there a work-around? Or how do I request the Ubuntu managers to rectify this? addenda On Synaptic i selected digikam to be installed. it downloaded all the dependencies but the 2 in question were not found - the message it gave "W: Failed to fetch security.ubuntu.com/ubuntu/pool/main/libk/libkdcraw/… 404 Not Found [IP: 91.189.91.13 80]". I google-searched the 2 files in the repositories to find that the version available there is ubuntu0.3 instead of ubuntu0.2.

  - by user86458

• Unable to install 12.10 on asus r500v

  - by bmdr38

  I have been unable to get beyond the grub boot screen of the live dvd/usb. The Try Ubuntu without installing, Install Ubuntu, etc menu shows, and I have tried adding/replacing nomodeset and no splash with neither helping. Even "Check disc for defects" does not display anything when selected. I am at a complete loss as to how to fix this one. I have had many successful installs in the past, but this is definitely a first for me. Just as FYI, Gfx card: Geforce GT 635M I realize this particular card has Optimus on it, however even the alternative boot/command line install fails to load. Any help would be appreciated. I realize there have been multiple threads on this, but none of the methods within them have solved this yet. Thanks

• Random MongoDb Syntax: Updates

  - by Liam McLennan

  I have a MongoDb collection called tweets. Each document has a property system_classification. If the value of system_classification is ‘+’ I want to change it to ‘positive’. For a regular relational database the query would be: update tweets set system_classification = 'positive' where system_classification = '+' the MongoDb equivalent is: db.tweets.update({system_classification: '+'}, {$set: {system_classification:'positive'}}, false, true) Parameter Description { system_classification: '+' } the first parameter identifies the documents to select { $set: { system_classification: 'positive' } } the second parameter is an operation ($set) and the parameter to that operation {system_classification: ‘positive’} false the third parameter indicates if this is a regular update or an upsert (true for upsert) true the final parameter indicates if the operation should be applied to all selected documents (or just the first)

• SOLVED BleachBit: How to Completely Clear URL History in Firefox?

  - by tSquirrel

  14.04 / Firefox 29.0 I've been using Bleachbit to clear usage/file history, and for the most part it works great. However, it doesn't seem to clear the website hostnames out of the URL, at all. These addresses are not bookmarked. Also, the total URL isn't preserved, just the hostname. Visit site http://www.bluesnews.com/some_random_URL_string Exit Firefox Run Bleachbit, with ALL Firefox options selected Restart Firefox Check history: completely empty, other than bookmarked sites. www.bluesnews is NOT bookmarked Type "blue" which is Firefox automatically completes as "http://www.bluesnews.com/" Alternate Step #3: Use Firefox's built-in "Clear History" and select ALL entries with a time frame of "Everything". Same result as above. My inquiry in BB forums hasn't been responded to. I found Dan's proposed solution, however changing autocomplete in about:config only turns off the function, it doesn't actually stop storing URLs. SOLVED - See my comment in the "Answer" response from Tim

• Resolution Independent 2D Rendering in XNA

  - by AttackingHobo

  I am trying to figure out the best way to render a 2d game at any resolution. I am currently rendering the game at 1920x1200. I am trying scale the game to any user selected resolution without changing the way I am rendering, or game logic. What is the best way to scale a game to any arbitrary resolution? Edit: I am trying to achieve this: http://www.david-amador.com/2010/03/xna-2d-independent-resolution-rendering/ but I think the code he has is for a different version of XNA because I cannot find that method overload he uses.

• Where is Nautilus icon file located and how is it chosen?

  - by Steve

  When I plug my Garmin Nuvi 265 GPS device into my computer via a USB cable, it mounts as a drive with a blue triangle icon instead of the default gray hard drive icon. HOW does Nautilus know how to do this? After much laborious searching, I found that the icon info is stored in ~/.gconf/apps/nautilus/desktop-metadata/GARMIN@46@volume/gconf.xml -- but only when a custom icon is selected. So Where is this blue icon file? Why does Nautilus use it instead of the plain drive icon? Is there a way to have give each of my drives a custom icon -- so that when I stick in my various flash drives, they have a distinctive icon (i.e. a 'favicon.ico' file on root or such?) Using Gnome 2.30.2 on Ubuntu 10.04.

• WiFi AdHoc Network: Unable to access peer by ip

  - by Pranav

  I've set up a WiFi AdHoc network in Maverick and selected the IPv4 settings as "Shared to other computers". On the client computer, I joined the network with the same SSID and set IPv4 method to Manual and I gave it an IP 10.42.43.2 (As on the first computer, the auto generated IP was 10.42.43.1). From either of the computers, I'm not able to access the other using the IP (in browser). Any idea why? (If I browse to 10.42.43.1 from the first computer, it works) Thanks!

  I have Unity & Gnome 3.4 installed successfully. All Dell keyboard keys work perfectly with both. I installed kde - full via terminal. Everything is working great except for the hotkeys.

Therefore, can someone tell me which suits best? Please note that, this shared storage need to be accessed by the other physical machines in the network. How to implement the selected solution for question #1? Any tutorials / guidelines / ebooks will be a great help and highly appreciated. Thank you in advance :)

• Building Interactive User Interfaces with Microsoft ASP. ...

  The ASP.NET AJAX UpdatePanel provides a quick and easy way to implement a snappier, AJAX-based user interface in an ASP.NET WebForm. In a nutshell, UpdatePanels allow page developers to refresh selected parts of the page (instead of refreshing the entire page). Typically, an UpdatePanel contains user interface elements that would normally trigger a full page postback - controls like Buttons or DropDownLists that have their <code>AutoPostBack</code> property set to True. Such controls, when placed inside an UpdatePanel, cause a partial page postback to occur. On a partial page postback only the contents of the UpdatePanel are refreshed, avoiding the "flash" of having the entire page reloaded. (For a more in-depth look at the UpdatePanel control, refer back to the

• How to print over ssh?

  - by mit

  I have the following configuration: P == U ---------------- W P is a HP Laserjet, connected to U, which is an Ubuntu 10.04 desktop machine with a standard gnome setup from the live cd. I just selected the HP Laserjet in the gnome printer admin and it works, I can print locally. W is a remote windows machine, server 2003, and --- is an untrusted connection. I wonder if I can create an ssh tunnel between U and W, so W can print using U's printer service. Which ports will I need to forward and what kind of printer must I add then on the windows machine?

• Ubuntu One not syncing and not providing feedback

  - by Joe

  Firstly, I apologize for not being more specific with my problem, but Ubuntu One is just not providing me with any information. It appears to be working, it states that "syncronization in progress..." but it never actually syncronizes (by never I mean 3 days). When I first selected a folder to sync using Ubuntu One it took on the order of hours to sync over 500MB of files - it uploaded the folder hierarchy first and populated the folders over a few hours. That is not happening at all now. Please let me know if there is a way I can get more information out of Ubuntu One that I can post and hopefully resolve this issue. Thanks, Joe

• how to list opened nautilus tabs with qdbus?

  I am trying to dig into qdbus for nautilus to get a list of opened tabs; I managed to do this so far: sites=(`qdbus |grep nautilus -i`); for siteSrc in ${sites[@]};do list=(`qdbus $siteSrc`); for path in ${list[@]}; do qdbus $siteSrc $path |sed -r "s|.*|$siteSrc $path &|"; done; done |sort -u #|grep paths -i for ex.: I was able to get a list of selected files with qdbus org.gnome.NautilusApplication /org/nautilus_actions/DBus/Tracker/0 org.nautilus_actions.DBus.Tracker.Properties1.GetSelectedPaths but I cant find a clue for opened tabs locations? (so we can use on scripts to restore them later)

• How can I have only two specific keyboard layouts in my system without 'us'?

  - by ??O?????

  I want only two keyboard layouts in my system: us altgr-intl (USA International (AltGr dead keys) ) and gr (Greece), so this is what I've selected in System ? Preferences ? Keyboard ? Layouts. However, every time I begin a new Gnome session (reboot, logout/login), the us keyboard layout is automatically inserted at the top of the list. I created a small script called fixlang that ensures the desirable result: layouts='[us altgr-intl,gr]' # tab between us and altgr key=/desktop/gnome/peripherals/keyboard/kbd/layouts active_layouts="$(gconftool -g $key)" if [ "$active_layouts" != "$layouts" -o "$1" == -f ] then gconftool -t l --list-type=str -s $key "$layouts" fi which I run on login. However, this is a kludge. How can I ensure that Gnome does not mess with my keyboard layout selection?

• My Oracle Support 6.3 - Knowledge Highlights

  - by JanSyss

  My Oracle Support 6.3 was released over the weekend (13-Oct-2012), and with that we released 30+ enhancements and 60+ bug fixes. Most important changes Search Suggestions are auto-correcting spelling errors, more suggestions for 'how to' type questions, enhanced usability to see the suggested additional terms. Improved Knowledge Base region on the My Oracle Support dashboard: recent searches from this region now retain the search attributions (e.g. pre-selected products or release). Search Tip: if the Knowledge Base region doesn't show up as the first region in the right column on the My Oracle Support dashboard, consider personalizing your dashboard to put it first, so that you right there for searching. Specifying the product you are researching an issue for, with optionally version and task as well, makes searches in the majority of the cases more precise. for more information, see my comments in my previous blog on the topic: https://blogs.oracle.com/supportportal/entry/mos_6_2_release Better support for searches on ORA-600 & ORA-700: no longer a difference in results between searching on 'ORA-600 [Arg1]' and 'Ora-00600: Internal Error Code, Arguments: [Arg1]'.

• How to upgrade from 11.10 to 12.04?

  - by Marco

  I am using 11.10 and I really want to update to 12.04 but it's impossible. I cannot see it in the update manager (I did select the option for the releases). I tried sudo update-manager d, and sudo-apt get upgrade and sudo apt-get upgrade release d but nothing. And sudo do-release-upgrade is not working as well! (I get "no release found" message.) So finally I did put on a live USB and when I boot, I click on install, then it's telling me that I do have 11.10 and I can select for erase all and install Ubuntu 12.04 or I can install along 11.10 and the second option to update 11.10 to 12.04 is grey. I cannot selected it! Why? Am I running out of options? What else can I do to upgrade to 12.04?
