• How to open the JavaScript console in different browsers?

  - by Šime Vidas

  Chrome: Press CTRL + SHIFT + I to open the Developer Tools. Click on the "Open console." icon in the bottom left corner. Safari: Press CTRL + ALT + I to display the Web Inspector. Click on the "Open Console." icon in the bottom left corner. Note: this only works if the "Show Develop menu in menu bar" check box in the Advanced tab of the Preferences menu is checked! IE9: Press F12 to open the developer tools. Open the Script tab, click the "Console" button on the right. Firefox 4: Press CTRL + SHIFT + K to open the Web console. What about Opera 11? Clarification: By console I mean the JavaScript console that lets you input and execute JavaScript code.

• Ubuntu slow on HP 2000 notebook with Apu e1-1200

  - by user169861

  I am using HP 2000 notebook which initially came with Windows 7 64bit. It has 4gb ram, AMD APU E1-1200 (1.4ghz) with Radeon 7310. With Windows it worked ok, so I decided to switch to Ubuntu. I installed 13.04 64bit at first, but responsiveness wasn't that good (opening windows, menus, Firefox, dash search) even if it was way better during the testing from live USB. I tried different kind of drivers for graphic card, 13.6beta, 13.4, fgrlx proprietary, upgraded kernel but the situation was the same. Then I tried installing 32bit version but the results were identical. After that I tried LTS version 12.04 and Xubuntu 13.04.. Responsiveness wasn't that different at all. Not sure what to do, and I wouldn't want to go back to Windows. This machine is not a beast, but it should be enough to deal with Unity or Xfce without troubles. Oh yes, I have insydeH20 BIOS with not so many options at my disposal. Thanks and best regards,

• Google explique son abandon du codec H.264, pour répondre aux critiques de ses concurrents

  Google répond aux critiques de ces concurrents en justifiant son choix sur le WebM le 17/01/2011 Google l'avait annoncé la semaine dernière, il abandonnait le codec H.264 sous Chrome pour passer au WebM. Une décision sur laquelle certains de ses concurrents ne se sont pas gênés pour le titiller. Google a décidé de répliquer avec son directeur de produit Mike Jazayeri, qui a expliqué que jusqu'alors, aucun codec n'était considéré comme un standard d'utilisation pour les vidéos en HTML5. FireFox lui même utilise le codec WebM au lieu du H.264 et ne reçoit pas de critiques. Google rajoute qu'il trouve regrettable que « les diffus...

• Is it possible to get a Proxy Authentication Dialog with Ubuntu Server?

  - by Johnny Bigoode

  I've got a VM Virtual Box with Ubuntu Server. I'set the http_proxy variable using export http_proxy="http://1234:linux@proxy:8080" The problem is that Ubuntu will constantly try to connect to the internet, even when I'm not logged in my company's account, so everyday I need to reset my password since Ubuntu will constantly try to access the internet. Also, it's always a problem when I need to authenticate the proxy with a different user/password. Can't I just set it to make a small prompt when it tries to connect to the proxy and fails? Like Firefox, Chrome and every app I have installed with Windows 7? I get this small dialog box that asks for a username and password when it can't access the internet. The Ubuntu Server doesn't need constant internet connection, specially since it's only online for tests over LAN.

• Keyword does not work in dash

  - by sev

  Since the last update of my OS ubuntu 11.10, I am not able to type in the dash. In any other application (like Firefox for this message), the keyboard is working fine, but in the dash "window" of unity (I am not sure what it is called officially), the keyboard is buggy. Sometimes I manage to enter one or two characters, but most of the time nothing appears as if the key-press signal was not received. Before the update, I actually was working with gnome-classic (I had removed unity from oneiric). The update seemed to have reinstalled unity, but something apparently is missing or damaged. Does anybody have a clue about what could be done to repair the dash?

• Is there a general rule of thumb for which browsers to optimize your site for?

  - by Christian

  I have a site (recently relaunched it with a new design) that I have put off optimizing for ie7 for far too long. I was just never too worried about it. The site is optimized for ie8-10, Firefox, Chrome, Opera, Safari, etc.. Then I asked myself, is it even worth it? I checked traffic over the last couple months before the relaunch and about 1.3% of the traffic is coming from ie7. So, is there a general cuttoff percentage when you would not optimize for a specific browser?

• In a browser, is it best to use one huge spritesheet or many (10000) different PNG's?

  - by Nick

  I'm creating a game in jQuery, where I use about 10000 32x32 tiles. Until now, I have been using them all separately (no sprite sheet). An average map uses about 2000 tiles (sometimes re-used PNG's but all separate divs) and the performance ranges from stable (Chrome) to a bit laggy (Firefox). Each of these divs are positioned absolutely using CSS. They do not need to be updated every tick, just when a new map is loaded. Would it be better for performance to use spritesheet methods for the divs using CSS background-positioning, like gameQuery does? Thank you in advance!

• Page not found in browsers

  - by Chetan

  I'm using ubuntu 12.04.1, last upgraded from 12.04 I'm using mts mblaze to access internet. Two days ago, I was using vpn on my system, suddenly cisco disconnected & my system hung while I was accessing my office system. I didnt' have any other idea, so I forcibly shut down the system. After that, connection is made, but firefox or chromium both don't find any page. I think there's some problem with the system package. Please let me know a good solution. Regards, Chetan

• Resize broswer window below 400px on OS X

  - by David

  Resizing Firefox windows (by dragging) works fine, up until the window is about 400 px wide, at which point the width of the web page content cease to follow the window with. I'm pretty sure it's not a CSS issue, and the same thing goes for Chrome and Safari as well (they won't even let me resize the window < 400 px wide). I can't understand where this limitation comes from. Is it a setting in the browser? A bug? A limitation of the OS?

• Uninstall Calibri font, installed from Windows' font directory

  - by donkeydown

  I use e PC with both Ubuntu and Windows-7 OSs. I tried to install the Calibri font for Ubuntu in this way: I did open the calibri.ttf file in the Windows/Fonts directory using Font Viewer and clicked on the Install button. Now I need to disintall that font but I can't. Font Viewer shows me "Calibri Regular" font is installed but does not allow me to disintall it. Font Manager does not show Calibri in the font list. Character Map does not show Calibri in the font list. Ubuntu Software Center and Synaptic don't find anything like "calibri". There is no calibri file in those directories: usr/share/fonts usr/local/share/fonts ~/.fonts The font is visible to LibreOffice, Chrome, Firefox.

• Minimum to install for a visual web browser in Ubuntu Server

  - by Svish

  I have set up a machine with Ubuntu Server. Some of the server software I want to run on it has web based user interfaces for setting it up et cetera. I know I could connect to it from a different machine which has a graphical user interface, but in this case I would rather do it on the box. So, from a fresh Ubuntu Server installation, what is the minimum I need to install to be able to launch a web browser I can use for this? For example chromium, firefox or arora.

• Why can we delete some built-in properties of global object?

  - by demix

  I'm reading es5 these days and find that [[configurable]] attribute in some built-in properties of global object is set to true which means we can delete these properties. For example: the join method of Array.prototype object have attributes {[[Writable]]:true, [[Enumerable]]: false, [[Configurable]]: true} So we can easily delete the join method for Array like: delete Array.prototype.join; alert([1,2,3].join); The alert will display undefined in my chromium 17,firefox 9 ,ie 10,even ie6; In Chrome 15 & safari 5.1.1 the [[configurable]] attribute is set to true and delete result is also true but the final result is still function(){[native code]}. Seems like this is a bug and chromium fix it. I haven't notice that before. In my opinion, delete built-in functions in user's code is dangerous, and will bring out so many bugs when working with others.So why ECMAScript make this decision?

• How do I provide arguments to an application launcher in kde?

  - by bobdobbs

  So I can create launchers in a quicklaunch thing on the kde desktop. The launchers are easy to create, and work most of the time. What I haven't figured out, is how to pass arguments to the applications that I want to launch. I want to launch the firefox profile manager and I also want to add a launcher for an emacsclient frame. For emacsclient, I've tried these: emacsclient -c "emacsclient -c" 'emacsclient -c' None of them work. When I click the launcher, the tiny emacs logo appears attached to the mouse pointer, and stays there for at least a couple of minutes, but no new frame opens. So, how can I actually open an emacsclient frame, or any other application with an argument from quicklaunch?

• Remove Kernel 3.1

  - by chazdg

  Is there a way to remove kernel 3.1 from Oneiric? I downloaded and upgraded to 3.1 with these instructions: Open the terminal and run these two commands for both 32-bit and 64-bit versions of Ubuntu 11.10/11.04: wget http://kernel.ubuntu.com/~kernel-ppa...241006_all.deb sudo dpkg -i linux-headers-3.1.0-030100_3.1.0-030100.201110241006_all.deb Ubuntu (64-bit) For Ubuntu 11.10/11.04 (64-bit), issue these commands: wget http://kernel.ubuntu.com/~kernel-ppa...1006_amd64.deb sudo dpkg -i linux-headers-3.1.0-030100-generic_3.1.0-030100.201110241006_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa...1006_amd64.deb sudo dpkg -i linux-image-3.1.0-030100-generic_3.1.0-030100.201110241006_amd64.deb Everything went well. I was able to reboot quickly, but Firefox and Chrome constantly crash with Kernel 3.1. I am using Gnome 3.2 and saw improvement with 3.0.0.13 provided by ppa. Any help with 3.1 or just removing it would be helpful. Thanks to all that reply.

• Google: What does a return to PR 'Unranked' mean?

  - by UpTheCreek

  One of my sites is very new (about 3 months). When first launched it's pages had (unsurprisingly) a Google PR of 'Unranked' [From Google toolbar stats, via the firefox SearchStatus plugin]. After a few weeks these changed to PR0. Just recently I noticed that they are showing PR 'Unranked' once more in Google Toolbar. As far as I know I'm following the Google guidelines. Results for the site still seem to be showing for its keywords. What could this mean?

• How can menu bars that require a right click be activated?

  - by Amos Annoy

  I've noticed that NetworkManager only has a single, left or right, click menu and no longer has an About menu option to show it's splash screen. In fact all the top bar mini short cut icons have been amputated and crippled leaving them with no rights. This severely impacts on our custom aps., similar to FireFox bookmarks, which can no longer be right clicked to bring up a context menu. It is possible to disengage FF's File|Edit|... menu bar from the top by running it in safe-mode so the menu bar is resident in a window, restoring right clicks, but our aps. do not have "safe modes". How can right clicks in menu bars be restored? reference

• How to Tweak the Low Battery Action On Your Windows 7 Laptop

  If you’ve got a netbook with really great battery life, you’ll probably still have loads of time left even with only 10% of the battery remaining. Here’s how to tweak the settings so it alerts you or goes into sleep mode at a more reasonable time.

• Moonlight stopped working on tvp.pl

  - by Oliverka

  Hello, I'm watching The Bold and the beautiful on the site: http://www.tvp.pl/seriale/obyczajowe/moda-na-sukces/wideo Yesterday I wanted to view next episode, however it didn't work. I checked various episodes from other points in time and none works. The "dots" that appear when a Silverlight video is loading are present, but after them there is only black screen (of death). I'm using Ubuntu Lucid Lynx 32 bit with GNOME2 and firefox 3.6. I have all updates done. Could somebody check if any video is working for them and tell me their setup, please? I'm using Moonlight 3. Two days ago everything was fine but later this problem appeared.

• Desktop interface crashes after software updates

  - by N.C. Weber

  Recently, after installing Ubuntu software updates on the evening of December 7th, 2012, my desktop interface crashes regularly leaving me with a command line screen with a long string of automated commands showing (I assume what goes on behind the pretty desktop). At first, I thought it was only crashing whenever I played DirectX games in WINE, but now it crashes if I open the native Firefox browser or if it's doing nothing at all but sitting there. Apport attempts to report the bugs after restart, but often they crash as well. I've done a SMART check on the hard drive, and everything report OK. No read errors, no bad sectors. I am using an Acer Extensa 4620Z Memory: 2.0 GiB Processor: Intel Pentium Dual CPU T2370 @ 1.73GHz x 2 GraphicsL: Intel 965GM x86/MMX/SSE2 OS: Ubuntu 12.10 32-bit Disk: 116.0 GB with 33.4 GB Available

• Is there a way to group 2 or 3 gui windows so that they don't get lost behind other open windows?

  - by Gonzalo

  For instance floating panels and main window in Gimp are independent windows. If I change focus to a full window (e.g. Firefox by doing Alt-Shift) and go back to the main Gimp window I don't get back the floating panels also (I have to change to them as well in order to see them). It would be great if the 3 windows can be "tied" (or linked) together in order that they don't get lost behind other open windows when I change back to (make active window) any of them? I think this configuration (if it exists) should show itself more obviously in the gnome environment. This question seems to address the same problem but it doesn't seem to be accurately answered.

• Ubuntu 12.04. Compiz Failure. Computer has nothing to use

  - by Teddy

  I updated to Ubuntu 12.04 with Compiz..now Compiz is failing and I have no tool bars or ways of getting to applications except for firefox from a link presented from sending an error report. How am I supposed to: Fix this mess with no navigation to get to the terminal, or software center. When will this problem be fixed? When I updated the system why didn't it change me back to the crappy Unity interface (No offense). If it can't be fixed how do I get my files back?

• Tor Vidalia Browser Problem

  - by SDW_1980

  So Vidalia is up and running fine but the browser has not installed properly, like it has before. Before I just clicked on the onion icon, it would say launching Tor..., You are now connected, the browser would start up and inform me I am connected to network with the browser page. Now, when I click Vidalia in the menu the onion icon appears at the top of my screen, which informs me I'm connected to the network. I can view a drop daown menu telling me about the network map and control panel but no browser to surf the tor network with. Is it because its a new version and using firefox normally is basically the same thing, because everything is now going through the tor network that way? Prob need to alter something or download the Browser seperatly don’t know. Thanks
