• Font rendering in Firefox is blurry

  - by Mehrdad

  A picture is worth a thousand words... so does anyone know how to fix this font blurriness in Firefox? (You'll need to right-click the picture below go to View Image to view it full-size; it's too small to see anything here.) Note: My other applications (and the Firefox non-client area, as you can see in the screen) are completely fine, so obviously going to System-Appearance and changing the font settings isn't fixing the situation. Edit: Not letting web pages to use their own fonts also doesn't help: See how the upper one is still sharper? Also, Firefox's own menu bar doesn't render the same way as the page content (menu bar below, page content above). They're both Segoe UI:

• Few specific questions on how games are developed

  - by russ

  When it comes to programming games from the old school sega games like sonic to indie games or angry birds or even to more advance games like Diablo, how exactly is level design done? As in, are the levels sometimes designed straight out of code in an IDE? Or do they create a visual level design editor where things can be placed at the click of a mouse button? I'm imagining old school games or very simple ones like indies are done via code, where extremely complicated ones require a visual editor. Is this correct? Also, when it comes to libraries like SDL or XNA, how often are these used rather than just utilizing OpenGL or DirectX? What about creating your own game engine vs utilizing one already made? Do most use already built engines? This question is directed toward the whole gaming spectrum of indie/big game development. Thanks.

• How to set x509 Certificate private key access rights for AppPoolIdentity

  - by ChrisD

  If your website uses the AppPoolIdentity and requires access to the private key of an x509Certficate, you’ll need to grant the read permissions to the iis application pool.   To grant permissions to the AppPoolIdentity: Run Certificates.MMC (or Start->run->mmc.exe, Add Certificate Snap-In for LocalMachine) Select the certificate (Personal node on the certificate tree) , right click and Manage Permissions. Add a new user to the permissions list. Enter "IIS AppPool\AppPoolName" on the local machine". Replace "AppPoolName" with the name of your application pool.

• How to report a bug to developers? A programmers quest to educated on bug reporting.

  - by Ryan Detzel

  I'm hoping to get some tips and advice on how to educate the rest of the company on how to submit proper bug reports. Currently we get tickets like: When I click this link I get a 404. (They include the page that 404s and not the page that caused it) Sometimes the right column flows into the button column. (no screenshot or additional information) Changes to xxx does seem to be working right. (EOM) Does anyone have a bug submission process/form that guides users into submitting as much information as possible?

• Command line method to find disk usage of camera mounted using gvfs

  - by Hamish Downer

  When my camera was mounted on /media I could use the standard tools (df) to see the disk usage of the card in my camera. However now the camera is mounted using gvfs, and df seems to ignore it. I've also tried pydf and discus to no avail. The camera is definitely available through nautilus, and when I select the camera in nautlius, the status bar tells me the amount of disk free. I can also open the ~/.gvfs/ folder in nautilus and right click on the camera folder and get the disk usage in a graphical way. But that is no use for a script. Are there command line tools that are the equivalent of df for gvfs filesystems? Or even better, a way to make df report on gvfs filesystems?

• Problems with opening CHM Help files from Network or Internet

  - by Rick Strahl

  As a publisher of a Help Creation tool called Html Help Help Builder, I’ve seen a lot of problems with help files that won't properly display actual topic content and displays an error message for topics instead. Here’s the scenario: You go ahead and happily build your fancy, schmanzy Help File for your application and deploy it to your customer. Or alternately you've created a help file and you let your customers download them off the Internet directly or in a zip file. The customer downloads the file, opens the zip file and copies the help file contained in the zip file to disk. She then opens the help file and finds the following unfortunate result:     The help file  comes up with all topics in the tree on the left, but a Navigation to the WebPage was cancelled or Operation Aborted error in the Help Viewer's content window whenever you try to open a topic. The CHM file obviously opened since the topic list is there, but the Help Viewer refuses to display the content. Looks like a broken help file, right? But it's not - it's merely a Windows security 'feature' that tries to be overly helpful in protecting you. The reason this happens is because files downloaded off the Internet - including ZIP files and CHM files contained in those zip files - are marked as as coming from the Internet and so can potentially be malicious, so do not get browsing rights on the local machine – they can’t access local Web content, which is exactly what help topics are. If you look at the URL of a help topic you see something like this:   mk:@MSITStore:C:\wwapps\wwIPStuff\wwipstuff.chm::/indexpage.htm which points at a special Microsoft Url Moniker that in turn points the CHM file and a relative path within that HTML help file. Try pasting a URL like this into Internet Explorer and you'll see the help topic pop up in your browser (along with a warning most likely). Although the URL looks weird this still equates to a call to the local computer zone, the same as if you had navigated to a local file in IE which by default is not allowed.  Unfortunately, unlike Internet Explorer where you have the option of clicking a security toolbar, the CHM viewer simply refuses to load the page and you get an error page as shown above. How to Fix This - Unblock the Help File There's a workaround that lets you explicitly 'unblock' a CHM help file. To do this: Open Windows Explorer Find your CHM file Right click and select Properties Click the Unblock button on the General tab Here's what the dialog looks like:   Clicking the Unblock button basically, tells Windows that you approve this Help File and allows topics to be viewed.   Is this insecure? Not unless you're running a really old Version of Windows (XP pre-SP1). In recent versions of Windows Internet Explorer pops up various security dialogs or fires script errors when potentially malicious operations are accessed (like loading Active Controls), so it's relatively safe to run local content in the CHM viewer. Since most help files don't contain script or only load script that runs pure JavaScript access web resources this works fine without issues. How to avoid this Problem As an application developer there's a simple solution around this problem: Always install your Help Files with an Installer. The above security warning pop up because Windows can't validate the source of the CHM file. However, if the help file is installed as part of an installation the installation and all files associated with that installation including the help file are trusted. A fully installed Help File of an application works just fine because it is trusted by Windows. Summary It's annoying as all hell that this sort of obtrusive marking is necessary, but it's admittedly a necessary evil because of Microsoft's use of the insecure Internet Explorer engine that drives the CHM Html Engine's topic viewer. Because help files are viewing local content and script is allowed to execute in CHM files there's potential for malicious code hiding in CHM files and the above precautions are supposed to avoid any issues. © Rick Strahl, West Wind Technologies, 2005-2012 Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Will my new HTML5 website decrease my Google ranking?

  - by Joshua

  Hi, I have a traditional HTML website that loads pages/sections of the site when people click on menu items. Pretty standard. Currently, I'm working on relaunching my website with a brand new HTML5 code & jquery that loads the whole thing, and just slides from one section to the next, sort of like this website: http://www.mino.pl/ My concern is that this will affect my ranking with google and websiteoutlook.com because it may seem like the website only has one page now instead of 8, making it look like I have less pageviews and making my site less relevant for search engine rankings. Are my concerns legit? If so, do you have suggestions on how to avoid it? I really like the idea of working with a page that 'slides' to different sections better than having pages load all the time. Any suggestions/thoughts would be very much appreciated. Thanks.

• New release of &quot;OLAP PivotTable Extensions&quot;

  - by Luca Zavarella

  For those who are not familiar with this add-in, the OLAP PivotTable Extensions add features of interest to Excel 2007 or 2010 PivotTables pointing to an OLAP cube in Analysis Services. One of these features I like very much, is to know the MDX query code associated with the pivot used at that time in Excel: You can find all the details here: http://olappivottableextend.codeplex.com/ It was recently released a new version of the add-in (version 0.7.4), which does not introduce any new features, but fixes a significant bug: Release 0.7.4 now properly handles languages but introduces no new features. International users who run a different Windows language than their Excel UI language may be receiving an error message when they double click a cell and perform drillthrough which reads: "XML for Analysis parser: The LocaleIdentifier property is not overwritable and cannot be assigned a new value". This error was caused by OLAP PivotTable Extensions in some situations, but release 0.7.4 fixes this problem. Enjoy!

• Blank space on right side of screen with XMonad/Gnome

  - by Andrew

  Fresh install of 11.10 x64. I set up XMonad with gnome-session as I did before on 11.04, following the guide on the Arch wiki. Everything works, but there's this weird vertical space about the size of a scrollbar on the side of the screen. The space is also above xmobar (the battery system tray icon is hidden behind it and I can't click it). XMonad weird space (since I can't post images) Is there some weird XMonad or Gnome option I'm missing? I don't even know where to begin to look.

• Is the 'C' in MVC really necessary?

  - by Anne Nonimus

  I understand the role of the model and view in the Model-View-Controller pattern, but I have a hard time understanding why a controller is necessary. Let's assume we're creating a chess program using an MVC approach; the game state should be the model, and the GUI should be the view. What exactly is the controller in this case? Is it just a separate class that has all the functions that will be called when you, say, click on a tile? Why not just perform all the logic on the model in the view itself?

• Firefox zombie process problem

This problem occurs with four computers (2 laptops and 2 desktops running ubuntu 10.04, 11.10, precise beta 1 and beta 2) I also have this same problem with other distros like Fedora 16, Linux mint 12, Debian 6 and Arch Linux. Thunderbird is also affected by this zombie process problem. Firefox safe mode does NOT help! Can someone help me to fix this problem?

• How can I prevent HTTPS on another domain from wrongly showing on my HTTP-only domain?

  - by Earlz

  So, I have a blog at domain.com. This blog is HTTP-only because I would gain almost nothing from adding SSL support. I have a web service now that I want to enable SSL support on that runs on the same server and IP address as my blog. I got it all working pretty easily, but not if I go to https://domain.com I will see a huge warning about an SSL certificate error and then if I click "ok" through the warning, I'll see the web service with SSL support, not my blog. My biggest fear with this scheme is Google indexing an HTTPS version of it and penalizing my blog because the content between the two doesn't match. How can I somehow for my blog's domain to either not serve anything on HTTPS, or to redirect back to my HTTP blog, or to serve my blog, but with an invalid SSL certificate? What can I do, preferably without buying another dedicated IP for my website?

• DNS slowdowns on development environment

  - by Sequenzia

  I have a local development environment setup on my Mac. I am running an Ubuntu Web Server inside of a Virtual Box VM. I setup a host file on my Mac that points my dev site to the IP of the Ubuntu Virtual Server. Everything works good other than the fact a lot (not all) of the time it takes more than 5 seconds to load a page. I used firebug to track down where the problem is and when it's slow the DNS part of my request is taking over 5 seconds. Like I said it's not all the time. Sometimes it resolves and loads the page within milliseconds. The same page one click will be super fast and then the next time it takes over 5 seconds. It's really slowing me down and I am not sure what is causing it. Anyone have any ideas? Any help would be great. Thank

• How to switch 'default' sound device controlled by hardware keys in Xubuntu?

  - by Ruth

  I installed xubuntu-desktop on a 12.04 Ubuntu upgrade after finding Gnome3 lacking. I've mostly been happy, but I've found an odd and frustrating bug. My laptop has two sound 'outputs' - an HDMI-out plug I never use, and the onboard speakers/headphones. For some reason, the hardware keys have been mapped to the HDMI output, even if I set it as 'fallback' in pavucontrol, and notify-osd only displays changes in the HDMI output (though the panel indicator volume control controls onboard sound). I'd ideally like both hardware keys and notify-osd to be looking at the onboard sound, though if I can't get notify-osd it's an acceptable loss. Having to click through a bunch of stuff to change volume is driving me crazy, though. Googling suggested that it /may/ be a Pulseaudio/ALSA conflict, but the hardware keys seem to change at least indicated volume in pavucontrol for HDMI as expected (I don't have an HDMI cable to test actual sound output)

• Bug unsubscribing from Ubuntu One Mobile

  - by rhino

  Hi guys, I have an Ubuntu One Mobile subscription, which I can see in my subscriptions page: one.ubuntu.com/account/subscription/756082 I no longer need my Ubuntu One Mobile subscription, so click the link to cancel the Mobile service subscription: one.ubuntu.com/account/cancel/756082/ Then confirm that request to cancel: one.ubuntu.com/account/cancel/756082/confirm/ But the process ends there showing a "Something has gone wrong page", and my subscription remains active :( The same problem occurred when I attempted the same a few weeks back, so not a temporary problem I'm thinking. Any input gratefully received. I would like to report this problem directly to the maintainer of this part of the Ubuntu site but cannot see how to do that.

• Ubuntu on AMD based Sony Vaio VPCY B15AG

  - by Gaurav

  Last week I bought a AMD E350 (AMD Fusion platform) based Sony VAIO (VPCYB15AG) having AMD Radeon HD 6310 graphics, I removed Windows that came along with and installed Ubuntu 10.10 (AMD64) using USB drive. During installation my touchpad was not working, I managed through keyboard, but after completing installation & restarting the machine still there was no touchpad support. Also there's no proper graphic card drivers. Even I tried connecting the USB mouse to it but the left key is not working and had to configure the mouse as left-hand to get the left click enabled. I tried searching for any possible solutions for these but found nothing helpful, is there any hope? What should I do to enable i) enable touch pad support ii) get higher resolution 1366x768, etc?
