• Google search preview shows content not on the website

  - by SDG

  My website google search entry is messed up. In the preview in google search results, I get things like cracks, serials, random ip addresses. I scanned all files and my computer for viruses and malware and could not find anything. I also tried to download and reupload all content from a friend's computer and still that content persists. I also scanned the source code of all files, but the content does not appear in any file. Google also does not detect any malware on the website, as seen in their webmaster tools. I have searched using the same keywords in other search engines such as bing and yahoo and the search results there are fine. I am quite clueless as to what the causes would be for this and what would be a possible remedy.

• Blank lines between sourcecode [closed]

  - by manix

  I'm so confused with a strange behaviour. Actually I have edited some php files remotely with my PhpDesigner8 (a php editor). Everything goes right, but when my teammates reopen the files that I have edited the source code have blank lines like below: class AdminController extends Controller { function __construct() { parent::__construct(); if (!$this->session->can_admin()) { show_error('Solo para administradores.'); } $this->load->library('backend'); } } Instead of class AdminController extends Controller { function __construct() { parent::__construct(); if (!$this->session->can_admin()) { show_error('Solo para administradores.'); } $this->load->library('backend'); } } Did you have experience these kinds of problems?

• How do I disable auto-away for online presence?

  - by Will

  I am using Natty with with classic GNOME desktop. I use Empathy and sometimes Skype. Both these get the online state from the system itself somehow. If I don't touch my keyboard for a few minutes - even when watching a YouTube clip or something - the inactivity triggers an auto-away state on my messaging apps. It's synchronized so I imagine its coming coordinated from the system, and not the two apps making the same decision individually. How can I disable this? I want manual control - I'm only away when I set it to away in a messaging app.

• Why do I get this error trying to compile libxml2?

  - by bfaskiplar

  Although, I installed libxml2 once and reinstalled it for a few times. I cannot compile c-source code because compiler cannot find where the header file is. I am able to locate where it is (in the folder where I downloaded the tar.gz package) but I had a feeling in my guts that this package isn't installed correctly because when I tried to sudo make install, it says /bin/bash: /home/bfaskiplar/Downloads/tar.gz: No such file or directory make[2]: *** [install-libLTLIBRARIES] Error 127 make[2]: Leaving directory `/home/bfaskiplar/Downloads/tar.gz packages/libxml2-2.8.0' make[1]: *** [install-am] Error 2 make[1]: Leaving directory `/home/bfaskiplar/Downloads/tar.gz packages/libxml2-2.8.0' make: *** [install-recursive] Error 1 that's why I installed synaptic package manager and reinstalled it, but in this case, isn't it supposed to put header files in default directory where gcc normally searches in currently, I am able to compile it with -I option, but I wonder why do I have to copy headers manually even if I used synaptic for installation and why I am getting Error 1 and Error 2 when trying to install the package manually. thanks in advance

• Opinion : quel avenir pour Firefox ? Le design et la communication l'ont-ils emporté sur les problématiques techniques ?

  Opinion : quel avenir pour Firefox ? Le design et la communication l'ont-ils emporté sur les problématiques techniques ? Historiquement connu comme un grand projet open source, dont la communauté a été secouée à plusieurs reprises (donnant naissance à quelques forks, dont Iceweasel), Firefox fait désormais la une comme un des grands acteurs de la navigation Web. Et ce n'est pas volé ! Outre les problématiques de sécurité, desquelles il s'est occupé très tôt, les innovations y ont été légion et nul doute que les navigateurs ne seraient pas ce qu'ils sont aujourd'hui sans cet acteur légendaire. Pourtant, depuis la version 3, une frénésie de sorties m'appelle à me poser de vraies questions s...

• Good places for starting to learn Lua scripting [closed]

  - by Cascalho

  I want to start learning to script in lua for game development. I could start with the official Lua tutorials, but I would rather study scripts that were written specifically for games and learn the syntax from there as I believe this is faster and more related to what I want. Can you recommend tutorials in video or text that are very detailed in explaining the code? Or some open source game with heavily commented code? What I want is something detailed that walks me through it, so I start understanding both the syntax and how each piece relate to each other, like "First of all, install this, this and that." "So, here we are defining a new function that will make the player jump." "This is the main script that calls the other ones. It defines these variables." "This function tests if the player is alive."

• No sound in World of Goo?

  - by user37805

  I installed WorldOfGooSetup.1.41.deb and it didn't work. There was a segmentation fault error (core dumped) in terminal. I fixed that with: sudo cp /usr/lib/x86_64-linux-gnu/libvorbis.so.* /opt/WorldOfGoo/libs32 sudo cp /usr/lib/x86_64-linux-gnu/libvorbis.so.* /opt/WorldOfGoo/libs64 That error is new for me as I have never had it before with previous releases of Ubuntu. The game starts now but no sound effects or music is played. I can hear music with my computer, videos, etc, so it is not a volume control problem. I am using ubuntu 12.04 final release.

• Unity LifeTimeManager for WCF

  I really love DI-frameworks. One reason is that it allows me to centralize life-time management of objects and services needed by others. Most frameworks have options to control the lifetime and allows objects to be created as Singletons, ThreadStatics, Transients (a new object everytime) etc. Im currently doing some work on a project where Unity [...]...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• nVidia GT 220 not working properly with Ubuntu 12.10

  - by Glaedr

  I used to enable proprietary nVidia drivers on every previous Ubuntu release to get it working properly (elseway I was forced to a very low resolution and no graphic acceleration), and everything worked fine then. In particular, I noticed - still I don't know why - that the GPU fan on every OS gets noisy until the video drivers are loaded (runlevel 5, it seems, in Linux), and then slows down to a normal speed. Today I installed 12.10. Running the Live CD, surprisingly, everything was working fine: full resolution, acceleration, silent fan, and so on. The running driver was nvidia-current (GT 216). After installing and booting I found that the fan was overrunning. The installed driver is nouveau. I tried installing nvidia-current, or any other proprietary driver, even installing the kernel headers & source and then the drivers (as suggested here), but all I'm getting with proprietary drivers is, the irony, low resolution, noisy fan and no acceleration (thus obviously unity and compiz refusing to start). Does anybody know a way out?

• Should we use python 2.6 or 2.7 or 3.x?

  - by lamwaiman1988

  The version of python which I am using is 2.6, and there is a 2.7 and 3.x. Usually I use python for some trivial program/snippet. I realize there are some major difference between 2.x and 3.x. I would really like to know, if I am going to make a bigger project with python, which version of python should I use? Should I upgrade to 2.7, or go to 3.x or stay with 2.6? The decision should be based on these terms: Number of user in the internet as a community. More users mean more open-source package and help from them. Functionality. Support from official development team. Compatibility for existing module/package. Thanks!

• Full screen: launchbar + panel overlaps when showing a dialog box

  - by user85921

  I'm developing a program for 12.04 that will run on full-screen, so I would like to have full control of what appears on the screen. However, when I show another window (possibly a dialog/message box), the Uunity Panel and Launcher appears on the top and left side of the screen. I've experienced this behavior with other applications (Firefox, Gnubg) as well when in full-screen mode. I tried to play with the settings, now my dialog box is hidden from the the taskbar, set to float on it's parent, which is my full screen window. The problem still exists. Is there a way to prevent these panels from showing up, when the new window isn't shown in taskbar, or it's parent is a full-screen window? Or do I need to completely disable them?

• Is there a mouse trail option?

  - by Tarlung

  I have intermittent blindness in my right eye. Windows had a great mouse option that made a trail of cursors behind the one that's functional. It made my mouse easier to see. The control button helps me find my mouse, but I need something to help me track it as it moves. Any help appreciated. Thanks in advance! PS: I prefer bash shell installs, copy paste easier then having to read small download link on websites.

• Moving two objects proportionally

  - by SSL

  I'm trying to move two objects away from each other at a proportional distance, but on different scales. I'm not quite sure how to do this. Object A can go from position 0.1 to 1. Object B has no limits. If object B is decreasing, then Object A should be decreasing at rate R. Likewise, if Object B is increasing, then Object A increases at rate R. How can I tie these two Object positions together so that in an update loop, they automatically update their positions? I tried using: ObjA.Pos += 0.001f * ObjB.VelocityY; //0.001f is the rate This works but there's an error each time it runs. ObjA starts off at its max position 1 but then the next time it will stop at 0.97, 0.94, 0.91 etc.. This is due to the 0.001f rate I put in. Is there a way to control the rate, yet not end up with the rounding error?

• Do ALL your variables need to be declared private?

  - by shovonr

  I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly loose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

• Javascript Only Search Method [on hold]

  - by user2118228

  I need to put a search function on a website that is going to be on a CD-ROM with no access to the internet. It has 80 pages, and about 500 'items', so I'd prefer to not have to hard code 100's of 'if statements if possible. I've found a few programs you can buy that will index and generate results (Zoom Search, JSS Index, The German Guys') but there are odd quirks with each one. Plus I would rather code it myself to get complete control over it, and to really understand what it's doing. Basically searching for a few words would display the product image and description; clicking on that would take you the related URL. This is kind of complicated, I can't find an easy solution not dealing with hundreds of if Statements. Has anyone ever created anything like this or know a better method? I'm not really sure a better way to go about this. I've used PHP/MYSQL for search results before, but this cannot run any php.

• Improve Your Database Unit Testing Skills and Win Free Stuff

  As the SQL Developer community grows to embrace the benefits of test-driven development for databases, so the importance of learning to do it properly increases. One way of learning effective TDD is by the use of code kata – short practice sessions that encourage test-first development in baby steps. I have a limited number of licences for SQL Test to give away free – just for practicing a bit of TDD and telling me about it. Keep your database and application development in syncSQL Connect is a Visual Studio add-in that brings your databases into your solution. It then makes it easy to keep your database in sync, and commit to your existing source control system. Find out more.

Did below but made no difference. sudo apt-get install bcmwl-kernel-source sudo modprobe -rv brcmsmac sudo modprobe -v wl What I do next? I tried Software&Updates and it showed 1 proprietary driver in use. This sounds like a WPA/WPA2 issue? Wifi works when I tried Zorin OS 7.1, wifi always worked in windows 7.

• C++ game architecture

  - by rxc

  I'm trying to make a game, but I'm not sure of the best way to set up the main loop and classes. For really small games, I could put everything in the main() loop, including event handling, collision checking, etc. However, for large games, that's seems like a highly inefficient way to get things done. The architecture I want is kind like the way the Minecraft coders did it (I quote Minecraft code because I've seen the source code when downloading MCP). They have objects entity classes EntityCow and EntityChicken and they have methods like onDeath(), onLivingUpdate(); and item classes like ItemSword have methods like onItemUse(). I've never seen these methods get called directly, but apparently, they get stored in a class called DataWatcher, which, I think "watches" all the data (as the name implies) and calls the appropriate methods in the objects. Is that how most games do it? If so, how is the DataWatcher class implemented? Any help or alternate suggestions is really appreciated.

• How can I prevent another site from trying to phish my customers by cloning the look and feel of my site?

Godaddy's staff said there is nothing they can do to prevent that site cloning the look and feel of my site. Is there anything I can do to stop another site from effectively cloning my site? How can I keep my customers from being duped by this?

• Software Design and documentation – what do people use that has proved valuable?

  - by eddyparkinson

  When creating software, what do you use to design, document and visualize. Looking for evidence/examples. e.g. Use cases, Pseudo code, Gantt chats, PERT charts, DFD, decision trees, decision tables (Answers maybe used to help teach students) What do you use to help with creating software. Also why; when has it proved valuable? --- Edit -- Proved valuable: The pattern so far suggests that the style of UML tool used is linked to an objective. e.g. "get it straight in MY head", explain to business mangers, quality control.

• Ubuntu 12.04 edit grub

  - by J. R. Crocker

  I just install Ubuntu 12.04. I want to change the boot order of grub. Previous versions of grub.cfg I was able to change the permissions and the do a gedit. After reloading 12.04, I was able to change permissions for grub.cfg, but gedit will not let me save it. I am a little irritated that Ubuntu is suppose to be open source. However someone has chosen to lock one out of a file. I do realize that some people have no business doing a edit on grub. I am a long time user of Unix and Linix.

• New Development Snapshot

  I finished all the .NET 4.0 security model changes. If you build from source, you can now (optionally) build on .NET 4.0 and get native .NET 4.0 assemblies that use the new .NET 4.0 security model (and also experimental class gc support). The .NET 2.0 binaries also work on .NET 4.0. This is probably the final development snapshot before the first 0.44 release candidate and it has been tested more than a typical development snapshot.
