  • OAuth request token for an installed application

    - by Andres
    Hi all I'm trying to use/understand Google request token mechanism. I intend to use it for an application I've start to develop to access Orkut data using OpenSocial API. I read this document that explains the steps to obtain a token for an installed application. This document tells you to use the OAuthGetRequestToken method from Google OAuth API to acquire a request token . Accessing the manual of this function (available here). But the parameter oauth_consumer_key, which is required, asks for the "Domain identifying the third-party web application", but I don,t have a domain, it is an installed application. So my question is, what should I put in this parameter in that case? I'm using oauth_playground to run my tests. Thx

  • Can the opensocial API remotely search for users in orkut etc.?

    - by Martin
    Does anyone know if (and how) I can build an application (Java/Ruby/whatever) doing REST or RPC calls to a social network like Orkut (using opensocial) to search for a user by name or email address? So far I know that I can list all friends for a particular user ID, but I want to search among all users. Would I need to code it as an app/gadget running inside the google sandbox or is there a way to get a list of matching user ID via REST? So far I got this one to work: http://code.google.com/p/opensocial-ruby-client/wiki/GettingStarted. But with this API and the gadget linked there I only get people that are already linked to me... Thanks for answers, Martin

  • "return false" is ignored in certain browsers for link added dynamically to the DOM with JavaScript

    - by AlexV
    I dynamically add an <a> (link) tag to the DOM with: var link = document.createElement('a'); link.href = 'http://www.google.com/'; link.onclick = function () { window.open(this.href); return false; }; link.appendChild(document.createTextNode('Google')); //someDomNode.appendChild(link); I want the link to open in a new window (I know it's bad, but it's required) and I don't want to use the target attribute. My code works well in IE and Firefox, but the return false don't work in Safari, Chrome and Opera. By don't work I mean the link is followed after the new window is opened.

  • Convert DVD to MKV (et al) without transcoding/recompression

    - by Oli
    Like a lot of people, I have a lot of DVDs. But we also have a stupid amount of disk space and a media centre (Boxee) so the DVDs are getting less and less use. It would be nice to convert our DVDs into something more relevant to our needs. I've dabbled with DVD ripping before but whereas I'd usually transcode down to a smaller picture size with a better video compression algorithm, this takes a silly amount of time. I don't have a couple of hours available for each disk. (Sidebar: is there dedicated, Linux-friendly hardware to improve h264 encoding performance?) So I was wondering if there's anything that take the DVD filesystem, De-CSS it, and then stitch together any the VOBs that make up the main part of the film and package that up in a wrapping format like MKV. A bonus would be if it could grab the subtitles and stick them in too but that's not a requirement as Boxee can grab the subtitles online if it needs to.

  • How can I generate a 2d navigation mesh in a dynamic environment at runtime?

    - by Stephen
    So I've grasped how to use A* for path-finding, and I am able to use it on a grid. However, my game world is huge and I have many enemies moving toward the player, which is a moving target, so a grid system is too slow for path-finding. I need to simplify my node graph by using a navigational mesh. I grasp the concept of "how" a mesh works (finding a path through nodes on the vertices and/or the centers of the edges of polygons). My game uses dynamic obstacles that are procedurally generated at run-time. I can't quite wrap my head around how to take a plane that has multiple obstacles in it and programatically divide the walkable area up into polygons for the navigation mesh, like the following image. Where do I start? How do I know when a segment of walk-able area is already defined, or worse, when I realize I need to subdivide a previously defined walk-able area as the algorithm "walks" through the map? I'm using javascript in nodejs, if it matters.

  • How to achieve a Gaussian Blur effect for shadows in LWJGL/Slick2D?

    - by user46883
    I am currently trying to implement shadows into my game, and after a lot of searching in the interwebs I came to the conclusion that drawing hard edged shadows to a low resolution pass combined with a Gaussian blur effect would fit best and make a good compromise between performance and looks - even though theyre not 100% physically accurate. Now my problem is, that I dont really know how to implement the Gaussian blur part. Its not difficult to draw shadows to a low resolutions buffer image and then stretch it which makes it more smooth, but I need to add the Gaussian blur effect. I have searched a lot on that and found some approachs for GLSL, some even here, but none of them really helped it. My game is written in Java using Slick2D/LWJGL and I would appreciate any help or approaches for an algorithm or maybe even an existing library to achieve that effect. Thanks for any help in advance.

  • GWT UIBinding cannot find zero-arg constructor

    - by aarestad
    I'm trying my hand at the new GWT 2.0 UIBinder capability, and I have a ui XML that looks like this: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:my='urn:import:com.mystuff.mypackage'> <g:VerticalPanel> <!-- other stuff --> <my:FileUploadPanel.ValidatingFileUpload styleName="field" ui:field="fileUpload" /> </g:VerticalPanel> ValidatingFileUpload is a non-static inner class contained in FileUploadPanel. It has an explicit zero-arg constructor that simply calls super(). However, when GWT starts up, I get this error: 00:00:18.359 [ERROR] Rebind result 'com.mystuff.mypackage.FileUploadPanel.ValidatingFileUpload' has no default (zero argument) constructors. java.lang.NoSuchMethodException: com.mystuff.mypackage.FileUploadPanel$ValidatingFileUpload.<init>() Any idea what might be going wrong here?

  • Async actions inside Silverlight Method - returning the value

    - by tyndall
    What is the proper way to call an Async framework component - wait for an answer and then return the value. AKA contain the entire request/response in a single method. Example code: public class Experiment { public Experiment() { } public string GetSomeString() { WebClient wc = new WebClient(); wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted); Uri u = new Uri("http://news.google.com/news?pz=1&cf=all&ned=us&hl=en&topic=t&output=rss"); wc.DownloadStringAsync(u); return "the news RSS from Google"; } private void wc_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) { //don't really see how this callback method makes it able // to return the answer I'm looking for on the return // statement in the method above. } } MORE INFO: The reason I'm asking this that I have a project I'm working on where I'd like JavaScript code in the browser to use Silverlight like a Facade/Proxy to Web services and complex calculations & operations. I'd like to make the calls to the [ScriptableMembers] in Silvelight synchronously. I don't want Silverlight to callback into the browser's JavaScript

  • Is finding graph minors without single node pinch points possible?

    - by Alturis
    Is it possible to robustly find all the graph minors within an arbitrary node graph where the pinch points are generally not single nodes? I have read some other posts on here about how to break up your graph into a Hamiltonian cycle and then from that find the graph minors but it seems to be such an algorithm would require that each "room" had "doorways" consisting of single nodes. To explain a bit more a visual aid is necessary. Lets say the nodes below are an example of the typical node graph. What I am looking for is a way to automatically find the different colored regions of the graph (or graph minors)

  • Unity Dash/Lens - Auto-completion based on recent search strings

    - by Anant
    Sometimes, I find myself typing the same (or quite similar) search strings inside a Unity Lens. So, I thought whether it's possible for the Lens to remember previous searches, and provide a drop-down menu of possible suggestions (based on the past) when I start typing my new query. With Lenses for sites like Wikipedia and DuckDuckGo, the search strings are getting longer, and this feature would lend a helping hand in filling out queries faster. This could be something applicable to all Lenses, with later versions allowing individual Lenses to run their own auto-completion algorithm.

  • Efficient way to sort large set of numbers

    - by 7Aces
    I have to sort a set of 100000 integers as a part of a programming Q. The time limit is pretty restrictive, so I have to use the most time-efficient approach possible. My current code - #include<cstdio> #include<algorithm> using namespace std; int main() { int n,d[100000],i; for(i=0;i<n;++i) { scanf("%d",&d[i]); } sort(d,d+n); .... } Would this approach be more efiicient? int main() { int n,d[100000],i; for(i=0;i<n;++i) { scanf("%d",&d[i]); sort(d,d+i+1); } .... } What is the most efficient way to sort a large dataset? Note - Not homework...

  • Regex to find external links from the html file using grep

    - by Amar
    hello, From past few days I'm trying to develop a regex that fetch all the external links from the web pages given to it using grep. Here is my grep command grep -h -o -e "\(\(mailto:\|\(\(ht\|f\)tp\(s\?\)\)\)\://\)\{1\}\(.*\?\)" "/mnt/websites_folder/folder_to_search" -r now the grep seem to return everything after the external links in that given line Example if an html file contain something like this on same line GoogleYahoo then the given grep command return the following result http://www.google.com">Google</a><p><a href='https://yahoo.com'>Yahoo</a></p> the idea here is that if an html file contain more than one links(`irrespective in a,img etc`) in same line then the regex should fetch only the links and not all content of that line I managed to developed the same in rubular.com the regex is as follow ("|')(\b((ht|f)tps?:\/\/)(.*?)\b)("|') with work with the above input but iam not able to replicate the same in grep can anyone help I can't modify the html file so don't ask me to do that neither I can look for each specific tags and check their attributes to to get external links as it addup processing time and my application doesn't demand that Thank You

  • How should I replan A*?

    - by Gregory Weir
    I've got a pathfinding boss enemy that seeks the player using the A* algorithm. It's a pretty complex environment, and I'm doing it in Flash, so the search can get a bit slow when it's searching over long distances. If the player was stationary, I could just search once, but at the moment I'm searching every frame. This takes long enough that my framerate is suffering. What's the usual solution to this? Is there a way to "replan" A* without redoing the entire search? Should I just search a little less often (every half-second or second) and accept that there will be a little inaccuracy in the path?

  • Android NDK Question

    - by Kyle
    The NDK does not contain very many shared libraries for you to access. As a result, I must build many sources myself and link them into my shared library via static/shared libraries. I want to compile libpng as a Static Library. Trouble is, I have absolutely no idea how, nor does google instruct you how to do so in their NDK. I'm no expert on the NDK even after reading everything I can find, so I would really appreciate someone who actually knows how this is done. I do have the Android.mk file for libpng, as google's Android OS source contains it. Infact, I got the entire directory on the android OS source for libpng and it's dependent libraries. It was somewhat of a shortcut instead of making one myself. I don't know how to make a particular directory which contains this file, though. Thanks for reading!

  • Including libraries in project. Best practise.

    - by mridang
    Hi guys, I'm writing a Python open-source app. My app uses some open source Python libraries. These libraries in turn use other open-source libraries. I intend to release my code at Sourceforge or Google Code but do I need to include the sources of the other libraries? Is this a good practice? ...or should I simply write this information into a README file informing the use about the other required libraries. I've placed all these libraries into a libs sub folder in my source directory. When checking my code into SVN, should I use something called svn:externals to link to other sources? Is there a way to dynamically update my libraries to the latest version or is this something I have to do manually when I release a new version. My sincerest apologies if my question sounds vague but I'm pretty lost in this matter and I don't know what to Google for. Thanks all.

  • A* Jump Point Search - how does pruning really work?

    - by DeadMG
    I've come across Jump Point Search, and it seems pretty sweet to me. However, I'm unsure as to how their pruning rules actually work. More specifically, in Figure 1, it states that we can immediately prune all grey neighbours as these can be reached optimally from the parent of x without ever going through node x However, this seems somewhat at odds. In the second image, node 5 could be reached by first going through node 7 and skipping x entirely through a symmetrical path- that is, 6 -> x -> 5 seems to be symmetrical to 6 -> 7 -> 5. This would be the same as how node 3 can be reached without going through x in the first image. As such, I don't understand how these two images are not entirely equivalent, and not just rotated versions of each other. Secondly, I'd like to understand how this algorithm could be generalized to a three-dimensional search volume.

  • Mapstraction: Changing an Icon's image URL after it has been added?

    - by Paul Owens
    I am trying to use marker.setIcon() to change a markers image. However it appears that although this changes the marker.iconUrl attribute the icon itself is using marker.proprietary_marker.$.icon.image to display the markers image - so the markers icon remains unchanged. Is there a way to dynamically change the marker.proprietary_marker.$.icon.image? Add a marker. Check the icon's image url and the proprietary icon's image - they're the same. Change the icon. Again check the Urls. Now the Icon Url has changed but the marker still shows the old image which is in the proprietary marker object. <head> <title>Map Test</title> <script src="http://maps.google.com/maps?file=api&v=2&key=Your-Google-API-Key" type="text/javascript"></script> <script src="mapstraction.js"></script> <script type="text/javascript"> var map; var marker; function getMap(){ map = new mxn.Mapstraction('myMap','google'); map.setCenterAndZoom(new mxn.LatLonPoint(45.559242,-122.636467), 15); } function addMarker(){ marker = new mxn.Marker(new mxn.LatLonPoint(45.559242, -122.636467)); marker.addData({infoBubble : "Text", label : "Label", marker : 4, icon: "http://mapscripting.com/examples/mashups/richter-high.png"}); map.addMarker(marker); } function changeIcon(){ marker.setIcon("http://assets1.mapufacture.com/images/markers/usgs_marker.png"); } function showIconURL(){ alert(marker.iconUrl); } function showProprietaryIconURL(){ alert(marker.proprietary_marker.$.icon.image); } </script> </head> <body onload="getMap()"> <div id="myMap" style="width:627px; height:412px;"></div> <div> <input type="button" value="add marker" OnClick="addMarker();"> <input type="button" value="change icon" OnClick="changeIcon();"> <input type="button" value="show icon URL" OnClick="showIconURL();"> <input type="button" value="show proprierty icon URL " OnClick="showProprietaryIconURL();"> </div> </body> </html>

  • Why can't we use a Translucent system bars with and ActionBar

    - by Waza_Be
    While updating my apps to Kitkat, I just wanted to give them a gorgeous look on KitKat using the Translucent property: Translucent system bars You can now make the system bars partially translucent with new themes, Theme.Holo.NoActionBar.TranslucentDecor and Theme.Holo.Light.NoActionBar.TranslucentDecor. By enabling translucent system bars, your layout will fill the area behind the system bars, so you must also enable [fitsSystemWindows][4] for the portion of your layout that should not be covered by the system bars. My only concern is that I would like to use an ActionBar which sounds the opposite of what Google wants (both theme have NoActionBar: Theme.Holo.NoActionBar.TranslucentDecor Theme.Holo.Light.NoActionBar.TranslucentDecor As I don't plan to use some hacks or tricks to make it work, I just wanted to know if there was some correct way to achieve this or if this would be against Google guidelines.

  • Reverse horizontal and vertical for a HTML table

    - by porton
    There is a two-dimensional array describing a HTML table. Each element of the array consists of: the cell content rowspan colspan Every row of this two dimensional array corresponds to <td> cells of a <tr> of the table which my software should generate. I need to "reverse" the array (interchange vertical and horizontal direction). Insofar I considered algorithm based on this idea: make a rectangular matrix of the size of the table and store in every element of this matrix the corresponding index of the element of the above mentioned array. (Note that two elements of the matrix may be identical due rowspan/colspan.) Then I could use this matrix to calculate rowspan/colspan for the inverted table. But this idea seems bad for me. Any other algorithms? Note that I program in PHP.

  • Can a user connect to my web site using an Orkut account ? Like Facebook Connect but for Orkut

    - by preguntón
    Can a user connect to my web site using an Orkut account ? Just like Google Friend Connect or Facebook, but with Orkut. The idea is, the user goes to my web site, I have a "Connect using Orkut" button there, on click takes him to the Orkut login page, once s/he logins and grants access to my app, get's redirected to my web site with the Orkut ID as a parameter. The same procedure that works for Google Friend Connect and also Facebook Connect.... I haven't seen an example of this with Orkut. Can it be done ? Is there an Orkut Connect or similar ? If there is one such example could you please give me a link to it ? A sample in c# would be excellent, but I would be happy with a sample in any language. Any help will be appreciated

  • How can Swift be so much faster than Objective-C?

    - by Yellow
    Apple launched its new programming language Swift today. In the presentation, they made some performance comparisons between Objective-C and Python. The following is a picture of one of their slides, of a comparison of those three languages performing some complex object sort: There was an even more incredible graph about a performance comparison working on some encryption algorithm. Obviously this is a marketing talk, and they didn't go into detail on how this was implemented in each. I leaves me wondering though: how can a new programming language be so much faster? In this example, surely you just have a bad Objective-C compiler or you're doing something in a less efficient way? How else would you explain a 40% performance increase? I understand that garbage collection/automated reference control might produce some additional overhead, but this much?
