  • Silverlight Cream for January 11, 2011 -- #1024

    - by Dave Campbell
    1,000 blogposts is quite a few, but to die-hard geeks, 1000 isn't the number... 1K is the number, and today is my 1K blogpost! I've been working up to this for at least 11 months. Way back at MIX10, I approached some vendors about an idea I had. A month ago I contacted them and others, and everyone I contacted was very generous and supportive of my idea. My idea was not to run a contest, but blog as normal, and whoever ended up on my 1K post would get some swag... and I set a cut-off at 13 posts. So... blogging normally, I had some submittals, and then ran my normal process to pick up the next posts until I hit a total of 13. To provide a distribution channel for the swag, everyone on the list, please send me your snail mail (T-shirts) and email (licenses) addresses as soon as possible.   I'd like to thank the following generous sponsors for their contributions to my fun (in alphabetic order): and Rachel Hawley for contributing 4 Silverlight control sets First Floor Software and Koen Zwikstra for contributing 13 licenses for Silverlight Spy and Sara Faatz/Jason Beres for contributing 13 licenses for Silverlight Data Visualization controls and Svetla Stoycheva for contributing T-Shirts for everyone on the post and Ina Tontcheva for contributing 13 licenses for RadControls for Silverlight + RadControls for Windows Phone and Charlene Kozlan for contributing 1 combopack standard, 2 DataGrid for Silverlight, and 2 Listbox for Silverlight Standard And now finally...in this Issue: Nigel Sampson, Jeremy Likness, Dan Wahlin, Kunal Chowdhurry, Alex Knight, Wei-Meng Lee, Michael Crump, Jesse Liberty, Peter Kuhn, Michael Washington, Tau Sick, Max Paulousky, Damian Schenkelman Above the Fold: Silverlight: "Demystifying Silverlight Dependency Properties" Dan Wahlin WP7: "Using Windows Phone Gestures as Triggers" Nigel Sampson Expression Blend: "PathListBox: making data look cool" Alex Knight From SilverlightCream.com: Using Windows Phone Gestures as Triggers Nigel Sampson blogged about WP7 Gestures, the Toolkit, and using Gestures as Triggers, and actually makes it looks simple :) Jounce Part 9: Static and Dynamic Module Management Jeremy Likness has episode 9 of his explanation of his MVVM framework, Jounce, up... and a big discussion of Modules and Module Management from a Jounce perspective. Demystifying Silverlight Dependency Properties Dan Wahlin takes a page from one of his teaching opportunities, and shares his knowledge of Dependency Properties with us... beginning with what they are, defining them in code, and demonstrating their use. Customizing Silverlight ChildWindow Style using Blend Kunal Chowdhurry has a great post up about getting your Child Windows to match the look & feel of the rest of youra app... plus a bunch of Blend goodness thrown in. PathListBox: making data look cool File this post by Alex Knight in the 'holy crap' file along with the others in this series! ... just check out that cool Ticker Style Path ListBox at the top of the blog... too cool! Web Access in Windows Phone 7 Apps Wei-Meng Lee has the 3rd part of his series on WP7 development up and in this one is discussing Web Access... I mean *discussing* it... tons of detail, code, and explanation... great post. Prevent your Silverlight XAP file from caching in your browser. Michael Crump helps relieve stress on Silverlight developers everywhere by exploring how to avoid caching of your XAP in the browser... (WPFS) MVVM Light Toolkit: Soup To Nuts Part I Jesse Liberty continues his Windows Phone from Scratch series with a new segment exploring Laurent Bugnion's MVVMLight Toolkit beginning with acquiring and installing the toolkit, then proceeds to discuss linking the View and ViewModel, the ViewModel Locator, and page navigation.

Windows Phone 7 Animated Button Press Michael Washington took exception to button presses that gave no visual feedback and produced a behavior that does just that. Using TweetSharp in a Windows Phone 7 app Tau Sick demonstrates using TweetSharp to put a twitter feed into a WP7 app, as he did in "Hangover Helper"... all the instructions from getting Tweeetshaprt to the code necessary. Bindable Application Bar Extensions for Windows Phone 7 Max Paulousky has a post discussing some real extensions to the ApplicationBar for WP7.. he begins with a bindable application bar by Nicolas Humann that I've missed, probably because his blog is in French... and extends it to allow using DelegateCommand. How to: Load Prism modules packaged in a separate XAP file in an OOB application Damian Schenkelman posts about Prism, AppModules in separate XAPs and running OOB... if you've tried this, you know it's a hassle..

  • Pay Per Click Software

    - by Eddy Freeman
    What software do sites like www.shopzilla.com, www.become.com, www.kelkoo.com etc.. use for the Pay-Per-Click product listing campaigns they offer for their retailers. I am asking what kind of software do they use to know that a certain retailer's products has been clicked 50 times or 100 times(and then the cost of the click is deducted from his money-account) etc... Can someone point me to those kind of softwares? EDIT *Some Explanation :: * In a site like www.shopzilla.com, retailers will upload thier products(list their products on the site). Anytime a buyer clicks on a product to go the retailer's website, an amount of money(say $0.20) is deducted from his account(the money he has deposited in his account with shopzilla). A retailer can see how many times buyers have clicked on his products and how much money remains in his shopzilla accounts. Am looking for such softwares that comparison sites like shopzilla uses to run this type of campaigns. I hope it is clear now.

  • YouTube: Tips by Bitwise Courses on NetBeans

    - by Geertjan
    I really like the potential of YouTube in providing a platform for short info clips that take not much time to produce and about as much time to consume. Huw Collingbourne's Bitwise Courses channel is full of exactly this kind of YouTube clip. Several of his YouTube clips are about or make use of NetBeans. The related Twitter account is @bitwisecourses and the homepage is bitwisecourses.com. Here's a great example, the latest YouTube clip created by Bitwise Courses. Very clear and simple explanation, on a specific and narrow topic, and very short and sweet. And very useful! Didn't know about this feature myself. Direct link to the movie: https://www.youtube.com/watch?v=b0fKT_hFQpU Here's to more of these, they're wonderful. More such YouTube clips are needed, short and precise, on very specific topics. And I'm very happy to promote them, as you can see.

  • Slick and Timers?

    - by user3491043
    I'm making a game where I need events to happen in a precise amount of time. Explanation : I want that event A happens at 12000ms, and event B happens every 10000ms. So "if"s should looks like this. //event A if(Ticks == 12000) //do things //even B if(Ticks % 10000 == 0) //do stuff But now how can I have this "Ticks" value ? I tried to declare an int and then increasing it in the update method, I tried 2 ways of increasing it : Ticks++; It doesn't works because the update method is not always called every microseconds. Ticks += delta; It's kinda good but the delta is not always equals to 1, so I can miss the precise values I need in the if statements So if you know how can I do events in a precise amount of time please tell me how can I do this

    - by Gopinath
    YouTube is not only the best source of videos, but also for great music. Most of the Indian movie music albums are officially released on YouTube with high quality. I hear a lot of music on YouTube instead of streaming from dedicated music streaming websites as their quality is no match to YouTube. While it is possible to run YouTube in the background on desktop, it is not possible on smartphones and tablets as they stop the background YouTube app automatically. But a simple trick from tech guru labnol let you play YouTube videos on the background on iPhone/iPads running on the latest iOS 7. Here is a video demonstration of the trick Read detailed explanation of the trick at labnol and don’t miss to browse through hundreds of useful tips and tricks listed on the blog.

  • Where does this concept of "favor composition over inheritance" come from?

    - by Mason Wheeler
    In the last few months, the mantra "favor composition over inheritance" seems to have sprung up out of nowhere and become almost some sort of meme within the programming community. And every time I see it, I'm a little bit mystified. It's like someone said "favor drills over hammers." In my experience, composition and inheritance are two different tools with different use cases, and treating them as if they were interchangeable and one was inherently superior to the other makes no sense. Also, I never see a real explanation for why inheritance is bad and composition is good, which just makes me more suspicious. Is it supposed to just be accepted on faith? Liskov substitution and polymorphism have well-known, clear-cut benefits, and IMO comprise the entire point of using object-oriented programming, and no one ever explains why they should be discarded in favor of composition. Does anyone know where this concept comes from, and what the rationale behind it is?

  • In MATLAB, how can 'preallocating' cell arrays improve performance?

    - by Alex McMurray
    I was reading this article on MathWorks about improving MATLAB performance and you will notice that one of the first suggestions is to preallocate arrays, which makes sense. But it also says that preallocating Cell arrays (that is arrays which may contain different, unknown datatypes) will improve performance. But how will doing so improve performance because the datatypes are unknown so it doesn't know how much contiguous memory it will require even if it knows the shape of the cell array, and therefore it can't preallocate the memory surely? So how does this result in any improvement in performance? I apologise if this question is better suited for StackOverflow than Programmers but it isn't asking about a specific problem so I thought it fit better here, please let me know if I am mistaken though. Any explanation would be greatly appreciated :)

  • Will an Atheros AR928X work with WPA2?

    - by Tommy
    Basically I need only the answer to above question. Please think of that I am new to linux. For further explanation here is the full story: I have the following problem. My friends notebook (Vista) has got a trojan and refuses to work anymore. The Avira Rescue CD did not help either. So I tried an old (9.1) Ubuntu CD and backed up all the essential files. Since we have no Windows Install Disk we want to put Ubuntu on that notebook. But with the 9.1 version there is no WLAN. Systemtest tells me, that it finds an Atheros AR928X, but ifconfig does not show that and the network manager tells me there are no LAN/WLAN devices. So: does that work easier with the new Ubuntu version or is that network adapter a known troublemaker? And: if I get the adapter to work, will it work with the WPA2-network around here?

  • Ubuntu suddenly won't boot on a Mac

    - by emchristiansen
    I installed 11.10 in dual-boot mode following instructions here: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation Everything worked fine, until I recently updated from Mac OS 10.6.x to the latest 10.6.x (this was a minor update prompted by OS X). The update made the rEFIt screen disappear, so I ran Boot Repair and reinstalled rEFIt and everything worked. I accidentally left my computer without power while booted into Ubuntu, until it presumably died or hibernated itself. I have been unable to boot into Ubuntu since. I didn't see the GRUB screen when I selected Linux the rEFIt chooser. Then I reinstalled rEFIt and the Linux option disappeared from the rEFIt chooser. This is a link to the boot info collected by Boot Repair: http://paste.ubuntu.com/755543/ Any help would be appreciated, especially an explanation of what all these components are (EFI, MBR, GPT, GRUB), where they live on disk, how the system knows to find each component, and how they relate to each other. Thanks!

  • Permanently disabling touchpad in ubuntu 12.04

    - by Andreas
    I'm looking for a way to permanently disable the touchpad in ububtu 12.04 (my computer is a Lenovo Thinkpad Edge on which it isn't possible to disable it in the bios). I tried the applications GPointingDeviceSettings and synaptiks 0.8.1 as well as the applets touchpad-indicator and Jupiter. None of these does the trick of disabling the touchpad permanently. Jupiter comes closest - it remembers that I have disabled the touchpad after restart - but when I login after the computer has been in suspend mode, the touchpad is enabled again. Can anyone help me in disabling the touchpad possibly at a lower level so it won't in any way be enabled unless I choose to enable it? I'm totally new to linux so a detailed explanation would be much appreciated ... The links, so far, doesn't address my question. I have no problem turning the touchpad off and making it stay off after reboot but when I login after the computer has been in an altered power mode it's on again. Isn't there a way to permanently disable a device like touchpad?

  • Getting bank account information from a bank and displaying on a website [closed]

    - by Ali Syed
    Hello I am looking for a way to get bank account information (transactions and balance) from a financial institution and display it on a website. The question is vague intentionally.... Everything is open. I haven't chosen a bank, serverside technology or front end technology. The idea is to have a script run automatically periodically (once or twice a day) and get the latest account information from the bank server automatically. Probably something in the direction of OFX (Open financial exchange), HBCI (home banking c.. interface), fnts or something like it. Even working over a closed source API is not out of question: Wesabe or Mint or something. Paypal is not an option because it won't work in India or Pakistan. cheers *Explanation: I have an exclusive small club. My members make irregular payments. These transactions should be online for all MEMBERS (with login) to see *

  • Video Training Courses for Linux/Ubuntu?

    - by Anil
    I'm a software developer with more than 15 years of experience on Windows platform, focused on C#/.NET/SQL Server stack. Recently I decided to explore Linux and learn a new development technology stack which is completely unrelated to Microsoft. After a bit of (re)search/reading I picked Ubuntu as my starting point. As I'm really a Pluralsight addict, preferring video courses as a starting point for learning new stuff, I wanted to ask if there are any decent video courses for Linux generally or Ubuntu focused ones? Basically I'm searching for general explanation of OS structure, a bit of system administration, and maybe some considerations for development on Linux system.

  • Builder Pattern: When to fail?

    - by skiwi
    When implementing the Builder Pattern, I often find myself confused with when to let building fail and I even manage to take different stands on the matter every few days. First some explanation: With failing early I mean that building an object should fail as soon as an invalid parameter is passed in. So inside the SomeObjectBuilder. With failing late I mean that building an object only can fail on the build() call that implicitely calls a constructor of the object to be built. Then some arguments: In favor of failing late: A builder class should be no more than a class that simply holds values. Moreover, it leads to less code duplication. In favor of failing early: A general approach in software programming is that you want to detect issues as early as possible and therefore the most logical place to check would be in the builder class' constructor, 'setters' and ultimately in the build method. What is the general concensus about this?

  • What happens differently when you add a task Asynchronously on GAE?

    - by Ben Grunfeld
    Google's doc on async tasks assumes knowledge of the difference between regular and asynchronously added tasks. add_async(task, transactional=False, rpc=None) Asynchronously add a Task or a list of Tasks to this Queue. How is adding tasks asynchronously different to adding them regularly. I.e. what is the difference between using add(task, transactional=False) and add_async(task, transactional=False, rpc=None) I've heard that adding tasks regularly blocks certain things. Any explanation of what it blocks and how, and how async tasks don't block would be greatly appreciated.

  • What is Atomicity?

    - by James Jeffery
    I'm really struggling to find a concrete, easy to grasp, explanation of Atomicity. My understanding thus far is that to ensure an operation is atomic you wrap the critical code in a locker. But that's about as much as I actually understand. Definitions such as the one below make no sense to me at all. An operation during which a processor can simultaneously read a location and write it in the same bus operation. This prevents any other processor or I/O device from writing or reading memory until the operation is complete. Atomic implies indivisibility and irreducibility, so an atomic operation must be performed entirely or not performed at all. What does the last sentence mean? Is the term indivisibility relating to mathematics or something else? Sometimes the jargon with these topics confuse more than they teach.

  • How to change the sprite colors

    - by Mr_Qqn
    In my rhythm game, I have a note object which can be of different colors depending on the note chart. I could use a sprite sheet with all the different color variations I use, but I would prefer to parametrize this. (For information, a note sprite is compound with one main color, for example a red note has only red, light red and dark red.) So, how to change the colors of a sprite basing on a new color ? I'm working with opengl, but any algorithm or math explanation will do. :) Thanks

  • Rotate sphere in Javascript / three.js while moving on x/z axes

    - by kaipr
    I have a sphere/ball in three.js which I want to "roll" arround on a x/z axis. For the z axe I could simply do this no matter what the current x and y rotation is: sphere.roll_z = function(distance) { sphere.position.z += distance; sphere.rotation.x += distance > 0 ? 0.05 : -0.05; } But how can I roll it along the x axe? And how could I properly do the roll_z? I've found a lot about quateration and matrixes, but I can't figure out how to use them properly to achieve my (rather simple) goal. I'm aware that I have to update multiple rotations and that I have to calculate how far to rotate the sphere to match the distance, but the "how" is the question. It's probably just lack of mathematical skills which I should train, but a working example/short explanation would help alot to start with.

    I am using tags for my posts on my WordPress site. The content of my post is set in <article> tags, which is fine and now, I want to put the author link and tags in a <footer> tag, but I don't know if this is good for SEO reasons. I know that Googlebots are putting less weight if they see links in a footer, but will this effect my tag pages? Is there any harm? I would love to read a good explanation on this.

  • How do game programmers design their classes to reuse in AI, network and play and pass mode?

    - by Amogh Talpallikar
    For a two player game where, your opponent could be on the network, CPU itself or near you where you would play turn by turn on the same machine. How do people design classes for re-use ? I am in a similar situation and have no experience in making such complex games. But here is what I have thought, If I am a player object , I should only be interacting with the GameManager or GameEngine Singleton , from which I will get various notifications about the game status. I dont care where and who my opponent is, this GameManager depending upon the game mode, will interact with gameNetworkManager , or AI tell me what the opponent played. I am not sure about the scenario where we play and pass [turn by turn on same machine]. Hoping for a brief but clear explanation or at least a link to a similar resource.:)

  • What exactly is "Web API" in ASP.Net MVC4?

    - by James P. Wright
    I know what a Web API is. I've written API's in multiple languages (including in MVC3). I'm also well practiced in ASP.Net. I just discovered that MVC4 has "Web API" and without going through the video examples I can't find a good explanation of what exactly it IS. From my past experience, Microsoft technologies (especially ASP.Net) have a tendency to take a simple concept and wrap it in a bunch of useless overhead that is meant to make everything "easier". Can someone please explain to me what Web API in MVC4 is exactly? Why do I need it? Why can't I just write my own API?

  • How to hide Thinking at Work so that the Non-Programmers don't suspect Slacking?

    - by stesch
    Better programmers than me can write in essays about walking around with a coffee mug and call it programming. And it's perfectly accepted at a place that knows the business. Or see what Gregory House (TV show "House M.D.") does when he is thinking. But what about the other places where you are the only programmer? If you don't stare at boring stuff on the monitor for 8 hours straight, co-workers suspect you being a slacker. Yes, not the managers who see the output. Only the co-workers who see the process and can't relate to this kind of work. Yesterday I had to explain to a trainee of some other profession that software development is like flying. The explanation from the Hitchhiker's Guide to the Galaxy. I don't think she bought it.

  • Calculating instantaneous speed and acceleration for a simple Car software model

    - by Dylan
    I am trying to model a speedometer and tachometer for a simple software model of a car dashboard. I want this to be relatively simple, so for my purposes I won't likely simulate variables such as drag (or, assume that drag is a constant). But I would like to know the general formulas for: 1) Calculating the RPM, depending on a position of a graphical slider representing the accelerator. 2) Using this information to find the instantaneous speed (or, magnitude of instantaneous velocity?). I am not sure, in the case of 2), what other independent variables I need to consider. Do I need to consider the frequency of rotation of the wheels (assuming a fixed radius), in addition to the RPM? If anyone can give me a rough explanation plus relevant formulas, or alternatively direct me to other trusted resources online (I have had a hard time sifting through info and determining the accuracy), it would be much appreciated.
