• Android change Tab image (not backgound)

  - by user1143989

  I am using a TabHost which has 3 tabs. Each tab has a image + text. spec = tabHost.newTabSpec("MyTasks") .setIndicator(Html.fromHtml("<b><H2>My Tasks</H2></b>"), getResources().getDrawable(R.drawable.task )) .setContent(intent); tabHost.addTab(spec); I want to change image when I select a tab. I used following code to change it ... TabWidget tw = getTabWidget(); View leftTabView = tw.getChildAt(0); leftTabView.setBackgroundDrawable(getResources().getDrawable(R.drawable.tab1_drawable)); tab1_drawable is a xml (selector and items for each state). THIS IS SETTING AND CHANGING BACKGROUND NOT THE IMAGE I SET. How can I change it?

• Jquery: Setting permanent height to an specific tab & resize plugin

  - by charlieCodex

  I am working with jquery sliding tabs. I have found a resize plugin that helps the tabs adjust to expanding content. The only thing is that i want to set a permanent height to tab 1(st_content_1). The code i have below works but it is a bit faulty. Should place in the function if statements? Check for the height of the first tab and then set it? Or a any better solution? You can check my EXAMPLE. Jquery $('.st_tab_view').resize(function() { var height = 250 $('div#st_content_1').css('height', height+'px'); var $this = $(this); $this.closest('.st_view').css('height', $this.height()); });

• I have a tab delimeted file that I want to convert into a mysql table

  - by user320835

  I have a tab delimeted file that I want to convert into a mysql table. there are 25 tab delimeted fields in the text file. I can get the values in when I construct the SQL statement word by word and get each value individually stated in the VALUES part but when I try to get the list as a whole it does not work. Here is the code. I couldn't figure it out. Any ideas? lines=open(path, "r").readlines() for line in lines[1:]: linex=line.strip().split("\t") linex.insert(0,'sometextindex') try: cursor.execute('INSERT INTO variants VALUES(%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)',linex) except: print 'line number=',a,linex

• Is there any event sent to window when new tab opens from parent tab on click a anchor tag with target _blank?

  - by Justin John

  I need to write callback function on clicking an anchor with target="_blank". <a rel="external" href="http://twitter.com/" target="_blank"> <img src="twitter.png"> </a> I think, following code block will do it. $("a[target='_blank']").click(function() { // action required }); Is there any other way where we can get an event with new tab opens? For example: The unload event is sent to the window element when the user navigates away from the page. If I think same perspective, Is there any event sent to window when a new tab opens.

• How can I get Kubuntu to use my Multimedia keys

  - by tbruf13

  I have tried to get Kubuntu to use my multimedia keys, and I cannot figure out how to do this. This feature is default in Ubuntu and in Linux Mint. They just work. I have followed the KUbuntu wiki post on Multimedia keys. I tried to enable Multimedia maps with xmodmap. It did not work. I tried to use the KDE GUI and could not seem to make the function I wanted work. The functions I am trying to get to work are fn+F12 = skip song fn+F11 = previous song fn+F10 = stop fn+ F9 = play/pause. I know this is possible because it worked in Ubuntu and in Mint, but it does not work in Kubuntu. I have submitted a bug report on this issue. Disclaimer: I am using Kubuntu 12.04 I have looked at this post, but Is there a way to enable Ubuntu Keyboard shortcuts in Kubuntu? do not know what to call the keys in that program.

• How to make unity unresponsive in Unity session in precise?

  - by Anwar Shah

  Recently I wanted to test the a keyboard shortcut, which is supposed to kill X server (hence very useful when you have a crash). That shortcut is not dependent on any particular window manager (like lxde, unity, kwin etc). So, it must work, even when you have unresponsive window manager (as opposed to Alt+Ctrl+Backspace which kills the session, and bring you a login screen). That's why I interested to make my WM (unity) unresponsive. Is past, it was very easy. Opening a terminal, typing unity --replace and then force close the terminal, was the simplest procedure. But unfortunately, This is not true in Ubuntu 12.04, (they make it very robust) Because whenever I kill the terminal, Unity automagically restart itself. I also tried compiz --replace but wasn't successful. My question is: How can I make Unity unresponsive while I am in Unity session, so that window manager does not recognize any keyboard shortcut.

• How can I make gitosis distinguish between two users with the same username

  - by bryan kennedy

  I have a gitosis system that seems to be working correctly except for a common problem we run into where I can't distingush permissions between two users who have the same username, but different hosts. For example: [email protected] 's SSH key is in the key folder. And so is [email protected] 's SSH is also in the key folder. These two jsmith's are two different people on two different computers. However, when I configure them in the gitosis.conf file with the usernames jsmith@computer or jsmith@machine, it seems like each user just gets the same permission. Can gitosis not distinguish the full username (name and host)? If not, how do I deal with multiple users accessing our system with common usernames? Thanks for any help.

• Text selection CTRL+SHIFT+Cursor Keys?

  - by mark

  Hi, I'm used to this Windows behavior that using CTRL+SHIFT+Cursor Keys I can select text word-wise. CTRL+Cursor Keys jumps word-wise and I use that a lot in combination with SHIFT to select text. This seems to be a "Windows thing" because it just works in all application. Now turning to Ubuntu 10.04, it doesn't work. CTRL+SHIFT+Cursor Keys just behaves like CTRL+Cursor Keys, i.e. I jump between the words but I can't select them that way. Another gotcha: I use CTRL+Cursor Keys to move fast between words, press down SHIFT, release CTRL and move the Cursor Keys to select text char by char and it doesn't work either. I need to release both keys complete. Is there a way to enable this?

• keymapping when ssh-ing from mac to linux

  - by Yair

  I'm using Lion to ssh -X to a linux machine and work on some code thats located on it. I open up an editor on the remote machine (usually matlab) and program on it. My problem is that in the linux there is no concept of the command key. So if I want to copy some text from a local window to the editor that runs on the remote, I need to to command-c to copy, and then control-v to paste. This obviously drives me nuts. I was wondering if there is a way to change the keymapping such that the command key will be recognized as a control key on the remote processes. Or is this something I need to change on my local (mac) X configuration?

• Getting error while running apt-get update

  - by pradeepchhetri

  I am getting the following error while running apt-get update on all of the servers. W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8B48AA6247928553 W: Some index files failed to download, they have been ignored, or old ones used instead. The solutions available are: To login into each of the server and run the following command to import the gpg key for that repo. sudo gpg --keyserver hkp://subkeys.pgp.net --recv-keys 8B48AA6247928553 sudo gpg --export --armor 8B48AA6247928553 | sudo apt-key add - But this requires logging into all of the individual servers and run the above two commands. I am looking for a way to correct by working on apt-repo server. Is there any way to do that.

• Launch Rhythmbox using a Keyboard shorcut

  - by palerdot

  I use Rhythmbox all the time in my Ubuntu. Is it possible to have a custom shortcut like Ctrl+R in Ubuntu, which can launch the Rhythmbox window, even if it is playing in the background ? Since, the emphasis of Linux OS flavors is to use keyboards as much as possible instead of mouse, i thought this functionality might tremendously help me in my Ubuntu environment. The Keyboard shortcuts sections asks for a command; So, I'm not able to figure out how to give a custom keyboard shortcut to a program like Rhythmbox. I'm using 12.04 if that helps. Thanks.

• Creating encrypted database for work

  - by Baldur

  My boss posed this problem to me: Encrypted: We need an encrypted database for miscellanious passwords we use at work that are currently only in people's head. Easily accessable: Someone needs to be able to quickly access specific passwords, possibly at hectic moments. This requires any sort of public key management (keeping it on a USB key in a sealed envelope?) to be relatively easy. Access control: The system should have groups of passwords where only specific people have access to specific groups. Recoverability: We need to make sure passwords from one group aren't lost even if the only users with direct access quit or pass away—hence we need some way where (for example) any two members of senior management may override the system (see the treshold link below) and retrieve all the passwords with their key. The first thing that jumped into my mind was some form of threshold and asymmetric cryptography but I don't want to reinvent the wheel, are there any solutions for this? Any software should preferrably be free and open-source.

• How to set Fn+F2 to show battery's status throug OSD and not power statistics?

  - by papukaija

  In natty pressing Fn+F2 on my Samsung NC10 opened a new notification with the remaining battery power. After upgrading to Oneiric, it opens the power statistics. Is the a way to revert this change? Checking the battery status with the notification is much faster than finding it from the power statistics. I know that the remaining battery time can be set to be shown on the panel but I'm used to Fn+F2.

• OSX launchd plist for node forever process

  - by lostintranslation

  I am trying to write a launchd.plist file for my node server. I am using forever to run my node server. I would like the server to start on boot. I would also like to wait for the mongodb launchd plist to run first. I installed mongobb using homebrew and it came with a launchd.plist already. I have executed the following: $ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist plist for mongodb is: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>homebrew.mxcl.mongodb</string> <key>ProgramArguments</key> <array> <string>/usr/local/opt/mongodb/mongod</string> <string>run</string> <string>--config</string> <string>/usr/local/etc/mongod.conf</string> </array> <key>RunAtLoad</key> <true/> <key>KeepAlive</key> <false/> <key>WorkingDirectory</key> <string>/usr/local</string> <key>StandardErrorPath</key> <string>/usr/local/var/log/mongodb/output.log</string> <key>StandardOutPath</key> <string>/usr/local/var/log/mongodb/output.log</string> <key>HardResourceLimits</key> <dict> <key>NumberOfFiles</key> <integer>1024</integer> </dict> <key>SoftResourceLimits</key> <dict> <key>NumberOfFiles</key> <integer>1024</integer> </dict> </dict> </plist> If I shutdown the computer and restart mongodb fires up as it should. However my node server is not starting. Any ideas? <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <dict> <key>SuccessfulExit</key> <false/> </dict> <key>Label</key> <string>com.test.app</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/forever</string> <string>-a</string> <string>-l</string> <string>/var/log/app/app.log</string> <string>-e</string> <string>/var/log/app/app_error.log</string> <string>/data/server/app.js</string> </array> <key>RunAtLoad</key> <true/> <key>StartInterval</key> <integer>3600</integer> </dict> </plist> EDIT: writing to log file and I see this: env: node: No such file or directory I think this means that the node binary cannot be found. I can echo $PATH and /usr/local/bin is in my path. I can start node from the terminal. Ideas?

• How do I get the window id and tab number of a Terminal window using AppleScript via the ScriptingBr

  - by Gavin Brock

  I can open a Terminal tab using the following AppleScript: tell application "Terminal" set myTab to do script "exec sleep 1" get myTab end tell This returns a string like: tab 1 of window id 3263 of application "Terminal". This is great, I can see the window id 3263 and tab number 1 (although I don't know how to query myTab to get only these values). In the Cocoa ScriptingBridge, I can do: SBApplication *terminal; SBObject *tab; terminal = [SBApplication applicationWithBundleIdentifier:@"com.apple.terminal"] tab = [terminal doScript:@"exec sleep 1" in:nil] How do I get the window id and tab number from the tab object?

• Ensuring uniqueness on a varchar greater than 255 in MYSQL/InnoDB

  - by Vijay Boyapati

  I have a table which contains HTML entries for news pages. When I initially designed it I used URL as the primary key. I've learned the error of my ways because left-joining is super slow. So I want to redesign the table with an integer (id) primary key, but still keep the rows unique based on the URL. The problem is that I've found URLs longer than 255 characters, and MySQL isn't letting my create a key on the URL. I'm using an InnoDB/UTF8 table. From what I understand it's using multiple bytes per character with a limit of 766 bytes for the key (in InnoDB). I would really love suggestions on an elegant way of keeping the rows unique based on URL, while using an integer primary key. Thanks!

• Stuck part-way through installation of windows 7, upgrade product key, cannot cancel or finish installation

  - by user326520

  I'm trying to install Windows 7 (to get rid of Windows 8). I started the installation, cleared the minefield Microsoft has put in to stop me uninstalling 8, but forgot that my Windows 7 disk is an upgrade. So now I'm part-way through the 7 install. Can't go back, can't convince Microsoft that I have a valid key; I tried stopping the Windows 7 install and booting XP first, but I can't either - the unfinished Windows 7 install prevents that. Where's the way out? Update: Having spent some time with a Microsoft operative, I know why I can't install XP; this recent computer doesn't support IDE SATA mode, only AHCI. So the problem is: - straight install - key not valid - XP first before upgrade - XP cannot install due to newer HDD interface.

• Upgrade to Win7 with upgrade key and full disc

  - by Jamin

  I just ordered a retail copy of Windows 7 Professional Upgrade to finally upgrade my work computer from Vista. It's not scheduled to be delivered until Monday, though, and I was hoping to take my computer home and upgrade over the weekend. I already have a full retail (non-upgrade) disc for the same edition that I'd bought for myself, though. So can I use that disc to perform the install, and then just enter my upgrade key on Monday when it comes in? Will that make everything activate properly? Or do I need to wait till I get my actual upgrade-specific disc before I try to use my upgrade-specific key? Thanks in advance.

• Configure a wireless network that accepts any WPA2-PSK network key

  - by Michel

  I recently bought a UART WiFi module ( this one ) and configured it with right SSID but wrong password( and I don't know what it is ). The problem is that I can't reset this module to its manufacture settings and I can't connect to this module via serial port to configure it with some wire or cable. But I'm sure that my module is trying to connect my access point but with wrong network key ( because in logs of my access point I can see my module that trying to connect but it can't ) So, I wonder to know is there any way to create or configure a network (using some access point or something else) based on WPA2 Personal security that accepts any WPA2-PSK passwords ? Or is there any other solution for this problem ? If no, is there anyway to see what password this module using to connect to that network ? ( If yes, then I can change password of my network to that password and access to this module's admin panel ) I tried create an open network ( without any security key ) but my module just searches for WPA2 based networks ( I think ).

• Chinese IME - Shape toggle key won't save

  - by Mikhail Sayapin

  Hello everyone, Whenever I use Google IME or other IMEs like Sogou, I always encounter the same problem: half/full-width toggle. It's easy to set half-width by default in ime prefs, but toggle key is maintained by Windows, and here the fun begins. I use Win7 x64 Ultimate. Open the "Text services and input languages", go to "Advanced key settings". Here I see "Chinese (Simplified) IME - Shape Toggle" is set to "Shift+Space". When I try to change it, it appears as if it has changed, but if you click on "Apply" instead of "OK", or just open the window again, you can see it's still "Shift+Space". The same happens with disabling this toggle - disables and goes back on Apply or reopen. Not sure if it's a bug in Win7, so asking here. Please save me. :) Thanks!
