  • Where to find GUI code

    - by muffinz
    I've been rummaging through Unity's source code (Shell Interface) and I was a little curious about something; where in the code are you supposed to find positional code? I'll clarify a bit with some examples. How do you find in the code what tells the Launcher to sit on the left side of the screen? Where in the code does it tell the "Session" button on the panel (top) to sit at the very right of the screen? I guess my real question is how do I find this out for myself? I've looked through a big portion of the source code and can't find anything related to the actual position of these items, only their sub-items like text-align. Any guidance on this would be much appreciated.

  • How can I authenticate Ubuntu Software Center with user password?

    - by user71852
    I would like to be able to use the password associated with this account to install packages with the GUI. Ideally, I would change the settings so that any user with sudo permissions could install packages. If that is not possible, I would like to be able to list all users that should be able to install. I know that this involves making changes to Policy Kit, and I have read a page with a similar question. However, I must need information specific to my own problem, because all my attempts so far have failed.

  • Nouvelle étude de la répartition des systèmes d'exploitation mobiles, un graphique s'y penche par constructeur plutôt que par OS

    Nouvelle étude de la répartition des systèmes d'exploitation mobiles, un graphique s'y penche par constructeur plutôt que par OS C'est une question qui fait rage depuis toujours et à laquelle il est difficile d'apporter LA réponse, d'autant plus que les chiffres diffèrent suivant s'ils proviennent des éditeurs de systèmes d'exploitation ou bien des fabriquants de terminaux mobiles. Saura-t-on un jour avec certitude quel OS mobile domine le marché ? Un cabinet d'analystes tente d'apporter des statistiques claires et réalistes à ce sujet. En effet, quand il s'agit de l'observation des parts de marché par les utilisateurs de systèmes, c'est Android qui sort vainqueur (à 29% devant RIM et Apple qui son ex-aequo à 27 %).

  • how to use version control

    - by ptamzz
    I'm developing a web site in php in localhost and as modules of it gets completed, I upload it on the cloud so that my friends can alpha test it. As I keep developing, I've lots of files and I lose track of which file I've edited or changed etc. I've heard of something as 'version control' to manage all those but am not sure how it works. So, my question is: Is there an easy way/service/application available to me to track all the edits/changes/new files and manage the files as I develop the website. As Soon as I'm done with a module, I want to upload it on the cloud (I'm using Amazon Cloud Service). If something happens to the new files, I might want to get back to the old file. And maybe, in a click or two, I get to see the files which I've edited or changed since the last one I've uploaded?

  • Connect divs with (non-straight) lines [migrated]

    - by Snailer
    I'd like to develop my site with a layout that looks somewhat like houses with connected plumbing, or multiple computers connected to a network. Basically, the will be boxes floating in space, with lines connecting some of the boxes. I'd like these lines to have some turns in them as well (just simple 90 degree corners) rather than just a straight line. My question is what is the best way to achieve this, and perhaps a small example. My thoughts were to use: PHP and CSS: I could create a background grid and then, with some complicated algorithms, draw paths using the grid's borders. This would be more dynamic, but I'm not sure I can plot the math all by myself. just CSS: Perhaps this is as simple as making some pre-drawn lines like L-shapes and T-junctions, then just placing and scaling them. But I don't believe there's a way to scale an image by slicing it.. so the line width would be scaled and thus each image would look different. Any thoughts?

  • How to create a map-like (clouds) texture [duplicate]

    - by user16547
    This question already has an answer here: How do you generate tileable Perlin noise? 9 answers If you place a map of the world on a sphere, it will look like the image is continuous. Basically the left end of the image is sort of a continuation of the right end. You won't be able to see any cuts. I'm trying to create a clouds texture to add to my planet such that it will seem it has clouds. I managed to create the clouds in GIMP, however, I can't figure out how to make sure the left end of my image is a smooth continuation of the right end. For example if you were to map the below image to your sphere (I removed transparency to make it clearer), there would be a very obvious transition from the right end of the image back to the left end on your sphere. How would I create a texture such that I get rid of that? Sorry for my lack of terminology.

  • Is the php method md5() secure? Can it be used for passwords? [migrated]

    - by awiebe
    So executing a php script causes the form values to be sent to the server, and then they are processed. If you want to store a password in your db than you want it to be a cryptographic hash(so your client side is secure, can you generate an md5 using php securely( without submitting the user:password pair in the clear), or is there an alternative standard method of doing this, without having the unecrypted pasword leaving the clients machine? Sorry if this is a stupid question I'm kind of new at this. I think this can be done somehow using https, and on that note if a site's login page does not use https, does that mean that while the databse storage is secure, the transportation is not?

    I think that this question may not be suitable for this forum. But I need your help. I am planning to buy a remote pointing (not only just pointing, we will be able to track the slides) device for my powerpoint presentations. I always use Ubuntu and powerpoint with libreoffice impress. I have been looking products on amazon, most of them are either for Windows or MAC. I am not sure whether they will work on Ubuntu. I think that at least some of of you have been using a device for presentations on Ubuntu. It would be great if you share one that will work seamlessly with Ubuntu. Thanks.

  • Simple BizTalk Orchestration & Port Tutorial

    - by bosuch
    (This is a reference for a lunch & learn I'm giving at my company) This demo will create a BizTalk process that monitors a directory for an XML file, loads it into an orchestration, and drops it into a different directory. There’s no real processing going on (other than moving the file from one location to another), but this will introduce you to Messages, Orchestrations and Ports. To begin, create a new BizTalk Project names OrchestrationPortDemo: When the solution has been created, right-click the OrchestrationPortDemo solution name and select Add -> New Item. Add a BizTalk Orchestration named DemoOrchestration: Click Add and the orchestration will be created and displayed in the BizTalk Orchestration Designer. The designer allows you to visually create your business processes: Next, you will add a message (the basic unit of communication) to the orchestration. In the Orchestration View, right-click Messages and select New Message. In the message properties window, enter DemoMessage as the Identifier (the name), and select .NET Classes -> System.Xml.XmlDocument for Message Type. This indicates that we’ll be passing a standard Xml document in and out of the orchestration. Next, you will add Send and Receive shapes to the orchestration. From the toolbox, drag a Receive shape onto the orchestration (where it says “Drop a shape from the toolbox here”). Next, drag a Send shape directly below the Receive shape. For the properties of both shapes, select DemoMessage for Message – this indicates we’ll be passing around the message we created earlier. The Operation box will have a red exclamation mark next to it because no port has been specified. We will do this in a minute. On the Receive shape properties, you must be sure to select True for Activate. This indicates that the orchestration will be started upon receipt of a message, rather than being called by another orchestration. If you leave it set to false, when you try to build the application you’ll receive the error “You must specify at least one already-initialized correlation set for a non-activation receive that is on a non self-correlating port.” Now you’ll add ports to the orchestration. Ports specify how your orchestration will send and receive messages. Drag a port from the toolbox to the left-hand Port Surface, and the Port Configuration Wizard launches. For the first port (the receive port), enter the following information: Name: ReceivePort Select the port type to be used for this port: Create a new Port Type Port Type Name: ReceivePortType Port direction of communication: I’ll always be receiving <…> Port binding: Specify later By choosing “Specify later” you are choosing to bind the port (choose where and how it will send or receive its messages) at deployment time via the BizTalk Server Administration console. This allows you to change locations later without building and re-deploying the application. Next, drag a port to the right-hand Port Surface; this will be your send port. Configure it as follows: Name: SendPort Select the port type to be used for this port: Create a new Port Type Port Type Name: SendPortType Port direction of communication: I’ll always be sending <…> Port binding: Specify later Finally, drag the green arrow on the ReceivePort to the Receive_1 shape, and the green arrow on the SendPort to the Send_1 shape. Your orchestration should look like this: Now you have a couple final steps before building and deploying the application. In the Solution Explorer, right-click on OrchestrationPortDemo and select Properties. On the Signing tab, click “Sign the assembly”, and choose <New…> from the drop-down. Enter DemoKey as the Key file name, and deselect “Protect my key file with a password”. This will create the file DemoKey.snk in your solution. Signing the assembly gives it a strong name so that it can be deployed into the global assembly cache (GAC). Next, click the Deployment tab, and enter OrchestrationPortDemo as the Application Name. Save your solution. Click “Build OrchestrationPortDemo”. Your solution should (hopefully!) build with no errors. Click “Deploy OrchestrationPortDemo”. (Note – If you’re running Server 2008, Vista or Win7, you may get an error message. If so, close Visual Studio and run it as an administrator) That’s it! Your application is ready to be configured and fired up in the BizTalk Server Administration console, so stay tuned!

  • Can Tutorial "Dual Boot Windows 7 & Ubuntu 12.04" Used for Dual Booting Windows 8 & Ubuntu 12.10?

    - by Shyuan
    I previously used this tutorial to dual boot Windows 7 and Ubuntu 12.04 perfectly. Now I have upgraded my Windows 7 to Windows 8. And I would like to do a fresh install (and start all over again like the tutorial) of Ubuntu 12.10 replacing existing Ubuntu 12.04. I like the way the tutorial presents thus can anyone kindly let me know if the tutorial is compatible with what I wanna do now? I have tried doing little research whether this has been asked, but all I got are not too similar to my question, if there are topics like this I do apologise and feel free to close it. Hope to hear from the community. Thank you so much. :)

  • Testing complex compositions

    - by phlipsy
    I have a rather large collection of classes which check and mutate a given data structure. They can be composed via the composition pattern into arbitrarily complex tree-like structures. The final product contains a lot of these composed structures. My question is now: How can I test those? Albeit it is easy to test every single unit of these compositions, it is rather expensive to test the whole compositions in the following sense: Testing the correct layout of the composition-tree results in a huge number of test cases Changes in the compositions result in a very laborious review of every single test case What is the general guideline here?

  • Updating NVIDIA drivers from 295.40: What will happen to TwinView?

    - by Spice
    Right now, I have the NVIDIA proprietary drivers enabled without the Ubuntu-X repo, so the driver version is 295.40 (which is on the official Ubuntu repo) instead of the current 304.64 for my card, but I want to update to the current (using the Ubuntu-X repo). From what I heard, after 302.xx, NVIDIA started supporting RandR and removed TwinView. My question is, I have TwinView enabled for two monitors. If I update to the new version, what will happen to my TwinView settings? Will there be any extra work to do to migrate to the new driver?

  • Is there a language that allows this syntax: add(elements)at(index);

    - by c_maker
    Does a language exist with such a syntax? If not, what are some of the limitations/disadvantages to this syntax in case I want to write a language that supported it? Some examples: sort(array, fromIndex, toIndex); vs sort(array)from(index1)to(index2); Method signature would like this: sort(SomeType[] arr)from(int begin)to(int end){ ... } Update: Because there might be some confusion, I'd like to clarify... I meant this question as a general idea like this (not specific to sorting and possibly using keywords like from and to): In JAVA(like language): void myfancymethod(int arg1, String arg2){ ... } myfancymethod(1, "foo"); In imaginary language: void my(int arg1)fancy(String arg2)method{ ... } my(1)fancy("foo")method;

  • "Mega Menus" for SEO [duplicate]

    - by Thought Space Designs
    This question already has an answer here: How do I handle having to many links on a webpage because of my menu 4 answers I'm using the term "Mega Menus" loosely here. I'm redesigning my WordPress site (it's going to be responsive), and as part of the redesign, I was debating incorporating some sort of descriptive menu setup. For example, normal navigation drop down menus come in the form of unordered lists of links like so: <nav> <ul> <li> <a href="#">Link1</a> </li> <li> <a href="#">Link2</a> </li> <li> <a href="#">Link3</a> <ul> <li> <a href="#">Sub Link1</a> </li> <li> <a href="#">Sub Link2</a> </li> <li> <a href="#">Sub Link3</a> </li> </ul> </li> <li> <a href="#">Link4</a> </li> </ul> </nav> What I'm looking to do is build my drop down menus with more information than your standard menu. For example, I have a top level link named "Team", and under that link, I want to make a large drop down that contains head shots, headers (in the form of styled p tags) and brief (<100 words) descriptions of each team member (only 2 currently). I want to accompany this with a "Read More" link that takes you to their actual team page. This is just one example, of course, and the other top level links would also have descriptive drop downs in the same fashion. On mobile, I was planning on hiding the "mega menu", and delivering a standard unordered list of links. Here's what I was thinking for overall structure and syntax: <nav> <ul> <li> <a href="#">Home</a> </li> <li> <a href="#">About</a> </li> <li> <a href="#">Team</a> <ul> <!-- DESKTOP --> <li class="mega-menu row"> <a class="col-sm-6" href="#"> <div class="row"> <div class="col-sm-4"> <img src="#" alt="Team Member 1" /> </div> <div class="col-sm-8"> <p class="header">Team Member 1</p> <p>Short description goes here.</p> </div> </div> </a> <a class="col-sm-6" href="#"> <!-- OTHER TEAM MEMBER INFO --> </a> </li> <!-- END DESKTOP --> <!-- MOBILE --> <li> <a href="#">Team Member 1</a> </li> <li> <a href="#">Team Member 2</a> </li> <!-- END MOBILE --> </ul> </li> <li> <a href="#">Contact</a> </li> </ul> </nav> Can anybody think of any potential SEO ramifications of doing this? I'm not going to be loading these menus full of links, so it shouldn't hurt page rank, but what are the effects of having a good bit of text and maybe even forms within nav elements? Is there such a thing as overloading nav with HTML? EDIT: Here's an example of what the menu would look like rendered on desktop. I'm currently hovering the "Team" menu, but you can't see because my mouse went away when I took the screenshot. EDIT 2: This question is not a duplicate. I'm not going to have "too many" links in my menus. I'm wondering how having images and text inside of header navigation will affect my menus. Also, I don't just want "yes, this is bad" answers. Please cite your sources and be specific with reasoning.

  • Can Questions be Reopened After They've Been Closed by Some Self Appointed Gestapo Moderators? [migrated]

    - by GenericJam
    This is obviously begging to be shut down right away and have all my privileges revoked or whatever but why do some people feel they have the right to shut down legitimate discussion? Who decides what is a "real" question or topic of interest? If you don't think it's valid, just click somewhere else but it is really getting to me on this site and StackOverflow how many really useful questions are shut down because people are asking opinions not textbook facts. Questions like this one are genuinely useful. Don't shut them down. You are making this site less useful for everyone else. Do people get their kicks by just wandering around the site closing questions? It seems many of the same names appear on the "closed down" box. Just go to a different page, don't ruin everyone else's education the way they choose it.

  • What should I learn next?

    I am a CS major. I've taken 2 courses in C (Intro to C and CS1) and 1 introductory course to OOP with Java. I really like Java and feel that I have a firm understanding of OOP concepts. I am really interested in web development and would like to learn a programming language that can be used to build dynamic web applications. My question is what language should I learn? I've narrowed it down to python or ruby. Also, I want to learn a programming language that will help me get a job upon graduating. So essentially, I will use this particular language to build applications that will help me get a job in the future.

  • Multiple copies of JBoss acting as one? [migrated]

    - by scphantm
    I have a few ideas how to solve the problem, but one question about jboss clustering. Please, keep in mind these applications were written very poorly, that is why they require so much memory and there is nothing i can do about that right now. So, I have clustered applications on Jboss where the application was small enough to run on one box. Meaning that one machine could handle the load. But, the current problem is that i have been asked to run several systems on the same environment. Our machines are virtuals and due to limited hardware, are restricted to 8 GB RAM, which gives jboss about 7GB to itself. Unfortunately, that isn't enough to run the group of applications. Im constantly getting heap errors and crashes. If i cluster 2 or 3 jboss instances together, can i run applications that consume more resources than a single box can handle?

  • Force Gnome 3 to work

    - by nkg5
    I have Ubuntu 12.10 on dual-boot with windows XP. My PC specifications are AMD Sempron 2800+ 1,6GHz with 512 MB ram and ATI Radeon 9250 graphic card with 128 MB memory. As Unity works slow and I don't like it's look, I installed gnome-shell. But as you know, Gnome 3 won't work on it. But gnome classic without effects works great. Thing is, when I turn off windows (by holding the power button or pressing restart button) my resolution on Linux is changed to 1024x768, and I can only change it by turning off the PC and turning off it's power source. But it is not the problem. The problem is that it runs Gnome 3 after one restart, it also runs better than Unity. My question is: Can I somehow force gnome 3 to work always and disable some of it's effects so it can run better?
