  • Why Mobile Patents are Such a Mess

    Our patent system is so under-funded, its mission, criteria and processes so broken and ill-suited to today's economy that the best solution is to just dismantled the patent office and start over.

  • Allowing client to select data to return via REST interface

    - by CMP
    I have a rest service that is essentially a proxy to a variety of other services. So if I call GET /users/{id} It will get their user profile, as well as order history, and contact info, etc... all from various services, and aggregates them into one nice object. My problem is that each call to a different service has the potential to add time to the original request, so we would rather not get ALL the data ALL of the time if a particular client does not care about all of the pieces. A solution I have arrived at is to do something like this: GET /users/{id}?includeOrders=true&includeX=true&includeY=true... That works, and it allow me to do only what I need to, but it is cumbersome. We have added enough different data sources that there are too many parameters for that style to be useful. I could do something similar with a single integer and a bitmask or something, but that only makes it harder to read, and it does not feel very Restful. I could break it down into multiple calls so they would need to call /users/{id}/orders and /users/{id}/profile separately, but that sort of defeats the purpose of an aggregating proxy, who's purpose is to make clients jobs easier. Are there any good patterns that can help me return just enough data for each client, without making it too difficult for them to filter and select what they want?

  • Mobile (Portable) Website

    - by johnny_s
    I have an online presentation to do next week and I have it all ready to go. The website is html and css only (no db), and currently resides on my shared hosting account. Now although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives; host my site on two different domains or servers (but what about domain name)? have a portable XAMPP version on a USB (again, domain name)? possible fail-over site/location? Any advice or suggestions are welcome. Update Presentation will be carried out on their laptop, not mine. So I am unable to install any software.

  • Collision for mobile game

    - by zemiguel12
    I'm writing a little game in as3 using Starling, and I need to check collision between 2 boats that can rotate. I don't need the pixel perfect collision, but bounds collision is not enough too. The boat look more or less like this: I was thinking about create one square on the back of the boat and a triangle on the front, than for each boat, check if the square collide with the other boat square or triangle, and the same for the triangle. I just don't know how to do that, I don't know if it's possible with the Shape.hitTest, or if it's the best way to do that. What can I do?

  • How do I solve this indexOutOfBoundsException in my server send/receive thread?

    - by Stefan Schouten
    I am creating a multiplayer game in Java with a server and multiple clients. Everything runs perfectly, until I press the Kick-button in the server to kick a client. Error at receive thread of server, after kicking the first person who joined out of three: java.lang.IndexOutOfBoundsException: Index: 2, Size: 2 at java.util.ArrayList.rangeCheck(ArrayList.java:604) at java.util.ArrayList.get(ArrayList.java:382) > at networktest.Server$3.run(Server.java:186) at java.lang.Thread.run(Thread.java:722) The pointed line is the ois = new ObjectInputStream where I send datatype.

  • Configuring Novel iPrint client on ubuntu 13.10

    - by Mahdi Sadeghi
    Recently I have struggled a lot to make Novel iPrint client to work on my laptop. I need it to use Follow Me printers in our university(you can take your print form any printer). Using this tutorial from Novel, I tried to convert the rpm package and install it on Ubuntu 13.04 & 13.10. The post install script from installing generated deb package had a typo which I saw in post install messages and I fixed that. Now I have the client running. To see the client UI I installed cinnamon desktop(because unity does not have system tray and old solutions did'nt work to whitelist Novel clinet). I have iPrint plugin installed on firefox as well(I copied the shared object files to plugin directories). I try installing printers from provided ipp URL(which lists available printers on the server) with no success. After clicking the printer name I see this: I have various errors: Formerly firefox used to asked my network username/password for installing SSL printer but now it returns this: iPrint Printer - The printer is currently not available. However I can install non-SSL version but the printer location is either empty or points to: file:///dev/null even if I change it to the exact address which I see on working machines still it prints nothing. I have tried the novel command line tool, iprntcmd to print. It is being installed at: /opt/novell/iprint/bin/ msadeghi@werkstatt:/opt/novell/iprint/bin$ ./iprntcmd --addprinter ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me\ -\ IPP iprntcmd v05.04.00 Adding printer ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me - IPP. Added printer ipp://iprint.rz.hs-offenburg.de/ipp/Follow-me - IPP successfully. It adds the printer with empty location and again no print. What I found interesting is the log file at ~/.iprint/errors.txt with strange errors which I hope somebody here can understand. When I try to install the SSL printer I receive these logs(note that HP is my local printer and has nothing to do with iprint): Thu Oct 31 11:02:03 2013 Trace Info: iprint.c, line 6690 Group Info: IPRINT-lib Error Code: 4096 (0x1000) User ID: 1000 Error Msg: iPrint Lib - Bad URI type supplied (not IPP:, HTTP:, or HTTPS:).

It worked for me on linux mint maya with my old laptop as well. Is there anybody out there who can help me to solve these problems? I am really disappointed with Novell and our university support. PS. I had the same problemwith 13.04. No matter if I am within the network or I connect with VPN, I have the same issues.

  • Official and unofficial apps in the iOS, WP7, and Android marketplaces

    - by Bil Simser
    The last few months have seen people complaining about the lack of "official" apps in the Windows Phone marketplace. In fact a couple of months ago I wrote about this very thing here and if we really needed these official apps or could get by with third-party solutions. Recently a list of "Top 100 Mobile Apps" crossed my desk and it was curious. 40 iPhone apps, 40 Android apps, 10 WP7 apps, and 10 BlackBerry apps. Really? 10 for WP7? So I wondered if the media was just playing this up and maybe continuing to do what I think most vendors are doing which is treating Windows Phone as the red-headed step-child you keep in the basement while all along there's nothing wrong with them. I put together the list and went digging to see how many of the top 40 iOS and Android apps were also on the Windows Phone platform (sorry BlackBerry, you should just shut your doors right now). Here's the results. Note, these are all *free* apps. There might be other pay apps that have official representation across all mobile devices, I just chose to hunt these ones down because I'm cheap. In the top 40, I easily plucked out 20 that had official apps on all three platforms. These were: Amazon Mobile, ESPN Score Centre, Evernote, Facebook, Foursquare, Google Search, IMDB, Kindle, Shazam, Skype (yes, I know, in beta on WP7), SlackerRadio, The Weather Channel, TripIt, Twitter, Yelp, Flixster, Netflix, TuneIn Radio, Dictionary.com, Angry Birds, and Groupon. Hey, that's pretty good IMHO. 20 or so apps, all free, and all fully functional and supported (and in some cases, even better looking on the Windows Phone platform than the other platforms). A dozen or so more apps had official apps on some platforms but not all, so yes, there are gaps here. Here's a rundown of the hangers-on: Adobe Photoshop Express This looks great on the iOS platform and there's even an official version on droid. Hope Adobe brings this to WP7. There are other photo editing programs though if you go looking (maybe we can get Paint.NET to be ported to the phone?) BBC News A few apps offer news feeds but nothing official on the Windows Phone. The feeds are good but without video this app needs some WP7 love. Dropbox Again Windows Phone looses out here with no official app. There are a few third party ones that will help you along and offer most of the functionality that you need but no integration that an official app might bring. Epicurious Droid seems to be the trailer here as there are apps for it but nothing official (from what I can tell). Both iOS and WP7 have them. Flipboard It's sad with Flipboard as it's such a great newsreader. The only offiical app is for iOS but frankly the iPhone version looks horrible so without a tablet the experience here isn't that hot. Maybe with WP8. Currently there's nothing even remotely similar to this on the other platforms. Google+ Is anyone still using this? No official app for WP7 but some clones. Apparently there's no API so people are just screen scraping. Ugh. Mint.com This app has all kinds of buzz and a lot of votes on the application requests site. Official apps for iOS and droid. No WP7 love (yet). TED Quite a few TED apps on WP7 but nothing official. I think the third party ones suffice and some are pretty nice looking, taking advantage of the Metro interface and making for a good show. WebMD There's a third party app on WP7 here but nothing official. It seems to contain all the same information and functionality the official apps do so not sure if an official one is needed but its here for inclusion. The other apps in the top 40 were either very specific to the platform (for example all three of them have a "Find my Phone" app). There are others that are missing out on the WP7 platform like ooVoo, Words With Friends, and some of the Google apps (Google Voice for example). Since you can integrate your GMail account right into the Windows Phone (via linked inboxes) I'm not sure if there's a need for an official GMail app here. Looking at the numbers Windows Phone still gets the worst of the deal here with half a dozen highly popular "offical" apps that exist on the other mobile platforms and in some cases, nothing even remotely similar to the official app to compare. This doesn't include things like Instagram, PInterest, and others (don't get me started on those). Still, with over 20+ highly popular free apps all represented on all three mobile platforms I don't think it's a bad place to be in. The Windows Phone platform could get a little more love from the vendors missing here, or at least open up your APIs so the third party crowd can step in and take up the slack. P.S. these are just my observations and I might have got a few items wrong. Feel free to chime in with missing or incorrect information. I am after all human. Well, most of me is.

  • Example WCF XML-RPC client C# code against custom XML-RPC server implementation?

    - by mr.b
    I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side (server side PHP runs, by the way), what I would like to accomplish is to create a simplest possible client in C# using WCF. Let's say that Contract for service exposed via XML-RPC is as follows. [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. What's next? Thanks for reading! P.S. I have done my homework of googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big) classes, which implement correct IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

  • Desktop.getDesktop().browse(uri); will open web page on server or client side?

    - by Milan
    Hello everybody, I have a JSF application and when user click on button I want to open a web page. Desktop.getDesktop().browse(uri); probably opens a web page on server side, how to do it on client side? when i try Desktop.getDesktop().browse(uri); it works, but maybe its because I open the JSF application on localhost so I dont know if the opened uri is on server side or client side. In the specification for getDesktop() its written: getDesktop() Returns the Desktop instance of the current browser context. Thanks!

  • How to know when the Client is disconnected from Server in C#?

    - by menacheb
    Hi, I have a Client-Server program in C#. Here is the Server's code: ... String dataFromClient = ""; NetworkStream networkStream; TcpClient clientSocket; bool transfer = true; ... while (transfer) { networkStream = clientSocket.GetStream(); networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize); dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom); dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$")); .... } I want to make a condition that stop the loop when the Client is disconnected. How can I do that? Many thanks,
