  • Share buttons vs sharer urls

    - by TeeOh
    As some people might know, adding share buttons from Facebook and Twitter can cause a page to slow down. I've seen many sites pass on the common iframe implementations that these sites offer and simply create icons that link to a sharer url for better control of page performance. http://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fwww.cnn.com%2F&t=CNN%26s+website%27 However, I've also read that Facebook is dropping support for these links. For example, this link now redirects to the Like Button. http://www.facebook.com/facebook-widgets/share.php Here is an article noting that Facebook is deprecating/has deprecated it's share functionality and is sticking with the Like button. http://www.barbariangroup.com/posts/7544-the_facebook_share_button_has_been_deprecated_called_it I'm assuming this is the same for the sharing url. If the sharer url is no longer a reliable option, what other methods are there besides using 3rd party widgets (like Addthis)?

  • What to do when there are no logical user stories but separate development tasks?

    - by Alex. S.
    We need to generate a release in 3 weeks, and for the planning we are doing today we don't have coherent logical user stories from the backlog tasks. Is valid to match say each development task is equivalent to an user story? Methodologically what is the correct way of handling this?, because anyway we are going to have standup meetings and we are going to control the progress of the project against those development tasks. For example, we have things like: . Adapt ETL to process numeric lists . Adjust licensing component . Remove DTC and so on. So, for the planning poker and iteration planning is valid to use those tasks? if not, what is the alternative?

  • Starting application in same window with XFCE4 Terminal and i3

    - by Luke
    Since recently I'm enjoying the i3 tiled window manager. I did install the XFCE4 Terminal since it gives greater control over my terminal look and feel however but I have noticed an issue with starting GUI based applications. When I execute a GUI based application I want it take over the current terminal window. To do this I use exec, as in: exec eclipse This will open a new window and leave the terminal I started the application in open as well. In normal circumstances this is not much of a problem since I can easily do an Alt-W on the GUI app's window. However, for some applications, like a file manager, it is necessary to open in the same window. How can I make GUI application open in the same window rather than opening a new one?

  • Problems using PHP on a Plesk Windows dedicated server

    - by wpsmdouble
    I'm having a few issues with my dedicated Windows server that has a Plesk panel: 1.) I can't send e-mail via PHP's mail() function, it always returns the following error: SMTP server response: 550 Requested action not taken: mailbox unavailable or not local Which setting should I alter in order to enable sending mail? 2.) The exec() and passthru() PHP functions don't work; their outputs are blank even when I try to run simple commands such as dir. Is there an option that I can toggle in the control panel to enable this functionality?

  • How to achieve 'forward' movement (into the screen) using Cocos2D?

    - by lemikegao
    I'm interested in creating a 2.5D first-person shooter (like Doom) and I currently don't understand how to implement the player moving forward. The player will also be able to browse around the world (left, right, up, down) via gyroscope control. I plan to only use 2D sprites and no 3D models. My first attempt was to increase the scale of layers to make it appear as if the player was moving toward the objects but I'm not sure how to make it seem as if the player is passing around the objects (instead of running into them). If there are extensions that I should take a look at (like Cocos3D), please let me know. Thanks for the help! Note: I've only created 2D games so was hoping to get guided into the right direction

  • Running Mixed Physical and Virtual Exalogic Elastic Cloud Software Versions in an Exalogic Rack is now Supported

    - by csoto
    Although it was not supported on older versions, now as of EECS 2.0.6, an Exalogic rack can be configured in a mixed-mode: half virtual and half physical Linux: Flexibility to have physical and virtual environments on same rack. For example, production on physical and test/dev on virtual. Exalogic Control manages the virtual compute nodes on the rack. Physical compute nodes are managed manually (including PKeys). Option to change full physical to hybrid and hybrid to full virtual rack. User has an option to choose either the top or bottom nodes for physical or virtual deployment. For further information about how the compute nodes can be split up on the rack (into bottom or top half) to run either Oracle Virtual Server (OVS "hypervisor") or Oracle Linux, please take a look at MOS Note 1536945.1. Note: Solaris is not yet supported in the mixed configuration.

  • Avoiding null in a controller

    - by Kevin Burke
    I'm trying to work through how to write this code. def get(params): """ Fetch a user's details, or 404 """ user = User.fetch_by_id(params['id']) if not user: abort(404) # Render some template for the user... What's the best way to handle the case where the lookup fails? One principle says you should avoid returning null values from functions. These lead to mistakes and AttributeErrors etc. later on in the file. Another idea is to have fetch_by_id raise a ValueError or similar if no user exists with that id. However there's a general principle that you shouldn't use exceptions for control flow, either, which doesn't help much. What could be done better in this case?

  • Adding PPA on install

    - by trampster
    I have a app I am packaging for ubuntu. I don't like the idea that if included in the ubuntu repositories I will have no control over updating that application. I don't want my users stuck on an out dated version for up to 6 months. I also do not want my users to have to manually add a PPA themselves to get updates as the target user will not have the technical know how to do this. Is it OK to have my .deb add a PPA on install. So that I can roll out stable updates to my ubuntu users.

  • How Data Transfers differ on Smart Phones: Iphone vs. Android vs. Windows Phone

    - by MCH
    I am interested in how each individual smart phone is allowed to handle data transfers within a third-party app. I am interested in designing apps that allow customers to update, transfer, download, etc. data from their smart phone to their personal computer and vice-versa. (Ranging from just text, to XML, to a Relational Database) I only have experience with the Ipod Touch before and one particular app that maintained all the data on an online server, so to update the data on your pc or iphone you had to go online, are there other ways to do it? Like bluetooth, wireless LAN, USB, etc? I believe Apple has certain policies on this in order to control the App Store and individual Iphones. I suppose each company has a particular policy on how an app is allowed to transfer data to another system, does anyone have a good understanding of this? Thank you.

  • Getting Started with ADF Mobile Sample Apps

    - by Denis T
    Getting Started with ADF Mobile Sample Apps   Installation Steps Install JDeveloper 11.1.2.3.0 from Oracle Technology Network After installing JDeveloper, go to Help menu and select "Check For Updates" and find the ADF Mobile extension and install this. It will require you restart JDeveloper For iOS development, be on a Mac and have Xcode installed. (Currently only Xcode 4.4 is officially supported. Xcode 4.5 support is coming soon) For Android development, have the Android SDK installed. In the JDeveloper Tools menu, select "Preferences". In the Preferences dialog, select ADF Mobile. You can expand it to select configure your Platform preferences for things like the location of Xcode and the Android SDK. In your /jdeveloper/jdev/extensions/oracle.adf.mobile/Samples folder you will find a PublicSamples.zip. Unzip this into the Samples folder so you have all the projects ready to go. Open each of the sample application's .JWS file to open the corresponding workspace. Then from the "Application" menu, select "Deploy" and then select the deployment profile for the platform you wish to deploy to. Try deploying to the simulator/emulator on each platform first because it won't require signing. Note: If you wish to deploy to the Android emulator, it must be running before you start the deployment.   Sample Application Details   Recommended Order of Use Application Name Description 1 HelloWorld The "hello world" application for ADF Mobile, which demonstrates the basic structure of the framework. This basic application has a single application feature that is implemented with a local HTML file. Use this application to ascertain that the development environment is set up correctly to compile and deploy an application. See also Section 4.2.2, "What Happens When You Create an ADF Mobile Application." 2 CompGallery This application is meant to be a runtime application and not necessarily to review the code, though that is available. It serves as an introduction to the ADF Mobile AMX UI components by demonstrating all of these components. Using this application, you can change the attributes of these components at runtime and see the effects of those changes in real time without recompiling and redeploying the application after each change. See generally Chapter 8, "Creating ADF Mobile AMX User Interface." 3 LayoutDemo This application demonstrates the user interface layout and shows how to create the various list and button styles that are commonly used in mobile applications. It also demonstrates how to create the action sheet style of a popup component and how to use various chart and gauge components. See Section 8.3, "Creating and Using UI Components" and Section 8.5, "Providing Data Visualization." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 4 JavaDemo This application demonstrates how to bind the user interface to Java beans. It also demonstrates how to invoke EL bindings from the Java layer using the supplied utility classes. See also Section 8.10, "Using Event Listeners" and Section 9.2, "Understanding EL Support." 5 Navigation This application demonstrates the various navigation techniques in ADF Mobile, including bounded task flows and routers. It also demonstrates the various page transitions. See also Section 7.2, "Creating Task Flows." Note: This application must be opened from the Samples directory or the Default springboard option must be cleared in the Applications page of the adfmf-application.xml overview editor, then selected again. 6 LifecycleEvents This application implements lifecycle event handlers on the ADF Mobile application itself and its embedded application features. This application shows you where to insert code to enable the applications to perform their own logic at certain points in the lifecycle. See also Section 5.6, "About Lifecycle Event Listeners." Note: iOS, the LifecycleEvents sample application logs data to the Console application, located at Applications-Utilities-Console application. 7 DeviceDemo This application shows you how to use the DeviceFeatures data control to expose such device features as geolocation, e-mail, SMS, and contacts, as well as how to query the device for its properties. See also Section 9.5, "Using the DeviceFeatures Data Control." Note: You must also run this application on an actual device because SMS and some of the device properties do not function on an iOS simulator or Android emulator. 8 GestureDemo This application demonstrates how gestures can be implemented and used in ADF Mobile applications. See also Section 8.4, "Enabling Gestures." 9 StockTracker This application demonstrates how data change events use Java to enable data changes to be reflected in the user interface. It also has a variety of layout use cases, gestures and basic mobile patterns. See also Section 9.7, "Data Change Events."

  • Are "skip deltas" unique to svn?

    - by echinodermata
    The good folks who created the SVN version control system use a structure they refer to as "skip deltas" to store the revision history of files internally. A revision is stored as a delta against an earlier revision. However, revision N is not necessarily stored as a delta against revision N-1, like this: 0 <- 1 <- 2 <- 3 <- 4 <- 5 <- 6 <- 7 <- 8 <- 9 Instead, revision N is stored as a delta against N-f(N), where f(N) is the greatest power of two that divides N: 0 <- 1 2 <- 3 4 <- 5 6 <- 7 0 <------ 2 4 <------ 6 0 <---------------- 4 0 <------------------------------------ 8 <- 9 (Superficially it looks like a skip list but really it's not that similar - for instance, skip deltas are not interested in supporting insertion in the middle of the list.) You can read more about it here. My question is: Do other systems use skip deltas? Were skip deltas known/used/published before SVN, or did the creators of SVN invent it themselves?

  • Silverlight 4 + RIA Services - Ready for Business: Authentication and Personalization

    To continue our series,  In real business applications our data is often very valuable and as such we need to know who is accessing what data and control certain data access to only users with privilege.  Luckily this is very easy to do with RIA Services.  For example, say we want to let only authenticated users access our data in this example.   That is as easy to accomplish as adding an attribute, see line 2 below.    1: [EnableClientAccess] 2: ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Can you be a programmer and Business manager at the same time?

    - by the_knight5000
    Hello all, I think I'm struggled in some situation! We are a new start-up with 5 employees (2 Programmers). I'm the Technical Manager and that was so fine! Now I can see the fingers point to me to take the control of everything, as I've the big vision of what our organization do and play the role of CEO or General Manager! I want to, but I've no idea if it would be risky to our organization to make such a decision? How would managerial interrupts affect the technical productivity? Any tips or previous experience about such situation would help :) Thanks in advance!

  • What issues are there for doing freelance work?

    - by Telos
    I'm considering doing some contract work on the side of my normal job. I know that it will kill my free time, but I figure I can control when I'm doing projects and then get a little extra money or even eventually make it my full time job. But as I've never done this before, I'm wondering what issues people face to do this kind of work. For instance: how do you find customers? What difficulties do you normally face on a project? How do you deal with projects that are too large for one programmer to effectively complete? What about projects that need other skill sets (for instance web design for a web app?)

  • Is there a formal name for gradually activating software changes?

    - by g .
    At times when we develop new features or functionality, we gradually "turn it on" to ensure a smooth transition and minimal impact for users. Instead of one big sudden change, we are able to control with the configuration aspects of the functionality that make it more or less intrusive to the user. This is all done in the same release/version of the software, so no software development changes are required (unless bugs turn up that need to be fixed). For example, initially we may only perform logging or analysis of data without acting upon it. Or we make something optional for a period of time before it becomes compulsory. The idea is that this reduces the potential for problems either on the technical side as well as unexpected changes by the user. The question is, is there a formal name for this approach?

  • How to redirect keeping the referral without server-side redirects?

    - by sergilazaro
    I have an HTML page hosted in Dropbox that some external websites link to. I want to redirect to a different page using only HTML or Javascript, since I can't use any server-side redirects. My goal is to be able to keep the original referral information for analytics. I've tried different ways but they all end up showing up with no referral. So if a blog that I have no control over (B) links to my public static page on Dropbox (D), and I want a redirect to the new page hosted elsewhere (N), I would like for the analytics for N to be shown as B, not D. Is that even possible?

  • Should I understand SVN before I jump to GIT?

    - by John Isaacks
    I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

  • What Would You Consider Best Practice Workflow Tools For Web Application (PHP) Development?

    - by Zenph
    I'm really hoping somebody with more experience can edit the question as per my examples of answers: • using version control • test driven development • debugging code (xdebug for php) • use of UML diagrams • use of OOP for maintainable, reusable code • use of frameworks (like Zend Framework for php) for rapid application development Anything else or an elaboration of what I mentioned above? Basically, I'm in the middle of forming a team of developers (I'm a developer myself) and I'd like some advice on how professional programmers/designers etc should work together and what standards/paradigms they should use. Also, if anybody has any books or links on the subject I'd welcome that! I did find this which I guess satisfies what I'm looking for, or at least part thereof: http://www.ibm.com/developerworks/websphere/library/techarticles/0306_perks/perks2.html

  • GUI app for Bandwidth Shaping (Internet Speed Limiter)

    - by Luis Alvarado
    This is a similar question as this one: Limit internet bandwidth but in this case I am looking for a GUI app. The other question was 2+ years ago so a GUI might be available that I could use to not only monitor but also change the maximum speed at which clients can download. A WebApp or a GUI app will help. It needs to work on 12.04 or newer. Just to give an idea, I am looking for something similar to NetLimiter that gives me the control to know: How much Download/Upload speed an IP/Mac has (Assuming this is a LAN) Limit the Download/Upload speed for an IP/Mac. Option to say I what time a speed can be limited or not. Can cap when a certain amount has been downloaded/uploaded (Like 250MB per day)

  • Try/Catch or test parameters

    - by Ondra Morský
    I was recently on a job interview and I was given a task to write simple method in C# to calculate when the trains meet. The code was simple mathematical equation. What I did was that I checked all the parameters on the beginning of the method to make sure, that the code will not fail. My question is: Is it better to check the parameters, or use try/catch? Here are my thoughts: Try/catch is shorter Try/catch will work always even if you forget about some condition Catch is slow in .NET Testing parameters is probably cleaner code (Exceptions should be exceptional) Testing parameters gives you more control over return values I would prefer testing parameters in methods longer than +/- 10 lines, but what do you think about using try/catch in simple methods just like this – i.e. return (a*b)/(c+d); There are many similar questions on stackexchnage, but I am interested in this particular scenario.

I was reading an article in SciAm this morning about the possibility of a robot uprising. Dont laugh yet, this is a very real, if still quite remote possibility. The main idea that was described was that AI could rise one day to self-awareness and to an ability to improve itself through self-replication beyond human abilities to control it.
