  • Control Your SEO Efforts With a Link Tracker

    Link exchanges are great way to achieve visibility for your website but they can also be a monumental waste of time, effort, and money if you are not taking advantage of link tracker technology. For webmasters not familiar with exchanging links, they are a basic technique whereby you display another website's link on your website in return for your link on their site.

  • Control Media via Arduino

    - by Ohad
    I want to create an application that controls the volume, play next\last, stop\play and things like this (I don't know what they called) like in a keyboard. I have tried to find how to do this with Python\Java but I couldn't find how. The main idea is (if some-one knows what is arduino) to connect it to my PC (Ubuntu) and to get from it signals that gives me values and with this values to be able to change the volume and to do next song\video. Thanks to any one who help :)

  • Zend_Cache_Backend_Sqlite vs Zend_Cache_Backend_File

    - by Alekc
    Hi, Currently i'm using Zend_Cache_Backend_File for caching my project (especially responses from external web services). I was wandering if I could find some benefit in migrating the structure to Zend_Cache_Backend_Sqlite. Possible advantages are: File system is well-ordered (only 1 file in cache folder) Removing expired entries should be quicker (my assumption, since zend wouldn't need to scan internal-metadatas for expiring date of each cache) Possible disadvantages: Finding record to read (with files zend check if file exists based on filename and should be a bit quicker) in term of speed. I've tried to search a bit in internet but it seems that there are not a lot of discussion about the matter. What do you think about it? Thanks in advance.

  • XmlDocument caching memory usage

    - by mdsharpe
    We are seeing very high memory usage in .NET web applications which use XmlDocument. A small (~5MB) XML document is loaded into an XmlDocument object and stored in HttpContext.Cache for easy querying and XSLT transformation on each page load. The XML is modified on disk periodically so a cache has a dependency on the file. Such an application appears to be using hundreds of megabytes of RAM. I have experimented with requesting garbage collection on each request start, and this keeps the RAM usage far lower but I cannot imagine this is good practise. Does anyone have any suggestions as to how we can achieve the same goal but with lower RAM usage?

  • A scheme for expiring downloaded content?

    - by Chad Johnson
    I am going to offer a web API service that allows users to download and "rent" content for a monthly subscription fee. The API will either be open to everyone or possibly just select parties (not sure yet). Each developer must agree to a license, and they receive a developer key for their person. Each software application will have its own key as well. So then end-users will download the software which will interact with my service's API. Each user will have a key for each application as well (probably using OAuth). Content will be cached on first download and accessible offline via just the third-party application that cached the content. If a user cancels their subscription, I plan on doing the following: Deactivate the user's OAuth key for all applications. Do not allow the user's account to download new content via the API (and subsequently any software that uses the API). Now, the big question is: how do I make content expire if they cancel their subscription? If they cancel, they should not have access to content anymore. Here are ideas I've thought of (some of these are half-solutions, not yet fully fleshed out): Require that applications encrypt downloaded content using the user's OAuth key, making it available to only the application. This will prevent most users from going to the cache directory and just copying and keeping files. Update the user's key once a month, forcing content to re-cache on a monthly basic. Users could then access content for a month after they cancel their subscription. Require applications to "phone home" [to the service] periodically and check whether the user's subscription has terminated. If so, require in the API developer license that applications expire cache. If it is found that applications do not comply, their keys (and possibly keys for all developers) are permanently deactivated as a consequence. One major worry is that some applications may blatantly ignore constraints of the license. Is it generally acceptable to rely on applications abiding by the licensing constraints? Bad idea? Any other ideas? Maybe a way to make content auto-expire after x days? Something else? I'm open to out-of-the-box ideas.

  • How can I design a custom control in Javascript (possibly using jQuery)

    - by Mathieu Pagé
    I'd like to create a custom control in javascript. The goal is to create a building block that has methods, properties and events and render into a div. An example of one such control would be a calendar. It would render into a div, it would have properties that would define how it's displayed and what date is selected or highlighted, it would have methods to change the current month or to select some date and it would raise events when a day is clicked or the current month is changed by a user input. I can think of lots of way to implement this and I'm not sure what is the best way. I seem to remember that it's a bad thing to augment a DOM elements with properties and method, so I ruled that out. A jQuery plugin seems like a good idea, however I'm not sure if it's appropriate to create a plugin for each and every method my control would have so I could then use it like : $('#control').method1(); $('#control').method2(); And if I do use jQuery, where do I store the private data of my control? Another idea I got was to create a new kind of object that would have a reference to a div in which it could render it's elements. So what is the prefered way to do this. If I can I would like to do this as a jQuery plugin, but I'd need guidlines on how to create methods and where to store private data. I've loked at Plugins/Authoring on jQuery website and it did not helped that much in this regard.

  • PHP APC - Why is loading cached array op codes slow?

    - by Aaron Kreider
    I'm using APC to reduce my loading time for my PHP files. My files load very fast, except for one file where I define more than 100 arrays. This 270 kb file takes 200 ms to load. The rest of the files are full of objects, methods, and functions. I'm wondering: does OP code caching not work as well for arrays? My APC cache should be big enough to handle all of my classes. Currently 40% of my cache is free. My hit rate is 99%. apc.shm_size=32 M apc.max_file_size = 1M apc.shm_segments= 1 APC 3.1.6 I'm using PHP 5.2, Apache 2, and Windows Vista.

  • How to control an actor movement in UDK

    - by Mikalichov
    This might be very basic, but I couldn't find something relevant to what I need (see below). I am working on a very basic thing: a 3D environment with some buildings, and actors walking inside it. It looks like following: I mainly want to manage to have one actor standing around, idling, and another walking around the area. Right now, this is done through matinee + skeletal mesh groups, and forcing a looped animation on the actors: But I realize this is super caveman-level. So I've build an AnimTree, linking the idling and directional animations to the corresponding nodes. But then, I'm stuck. I added the AnimTree in the actors properties, but nothing happens. I've tried MoveToActor, but no success - is there a thing to set to allow an actor to move? Also, I place the actors on the map manually (they are supposed to be unique), should I spawn them instead? Every tutorial I find explains how to use an AnimTree for the player character, which is not what I want. I need a way to move the actors. I tried to look for AI tutorials, but only found UT3 bots-modifications, which is not what I need either. Since I have so much trouble finding how to do this through Kismet, I'm starting to suspect this has to be done through scripting/coding, but I would like to be sure there is no way to do it through Kismet before going that route. Every bit of answer about how to tell an actor something along the lines of "go in that direction as much as you can, then when you hit a wall turn 45° and continue" would be awesome. I'll be happy to move/edit the question if there is any problem with it

  • "Time Control" in a 2d Platformer

    - by Woody Zantzinger
    I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

  • Any advice for dynamic music control?

    - by Assembler
    I would like to be able to dynamically progress the score, and affect the volume levels of separate channels within the music. How could I do this? From my experience with mod music (olden days Amiga music, Mod Tracker, Scream Tracker, Fast Tracker II, Impulse Tracker etc etc), I believe this is the best way to tackle the problem, to allow the music to move from one loop to another, without anything mixed down. I want to do this in AS3, and am considering pulling apart Flod to make this happen

  • Mobile Web Framework that will only control rendering and page transitions

    - by rlemon
    I have been using jQueryMobile for a bit now, and there are some things I like about it and others I do not. First I will give a bit of background. I have a light weight mobile application that has a few configurations and 6 pages. Ideally I Would like to load all pages into the DOM (they interact with each other quite often and pages will be switched in the same frequency). The application will post for some JSON every n seconds and refresh the values on the page (yes it is primarily a information display app). with the jQuery Mobile framework the only real thing I like is how easy it is to have a standardized UI a crossed all devices and browsers, I'm really not using too much else out of the framework other than the basic page navigation (if you are familiar with the framework; a bare-bone multi-page design is all i need). Why I want to step away from jQueryMobile is how weighty it is. Not only do you need to include the mobile library, but also the base jQuery libraries. This I do not like because I'm not using jQuery anywhere else on the site. Any suggestions on light-weight mobile frameworks that have a similar rendering as jQueryMobile?

  • How To Remote Control Your Home Computer From Anywhere With VNC

    - by Chris Hoffman
    VNC allows you to remotely access a computer and use its desktop, either over the Internet or from another room in your house. Windows includes a Remote Desktop feature, but it’s only available in Professional editions of Windows. Some people may prefer TeamViewer or another service instead, but VNC allows you to install and manage your own server without using a centralized service. VNC clients and servers are available for all platforms, but we’ll be covering Windows here.

  • AMD control center doesn't save preferences

    - by Fault
    Everytime when I edit the monitor preferences in AMD to multi-monitor or to a multidesktop, when I press save or apply the program just closes with no errors and the preferences hasn't been saved. If I try to do it via the Displays app that is built-in in ubuntu 11.10 I get the following error: The selected configuration for displays could not be applied required virtual size does not fit available size: requested=(2560, 1024), minimum=(320, 200), maximum=(1280, 1280) I don't know if it helps but my graphics card is a ATI Radeon HD 4800 and my monitors are both 1280x1024. I'm running the proprietary driver without post-release updates because I always get an error trying to install that one.

  • Scuttlebutt Reconciliation from "Efficient Reconciliation and Flow Control for Anti-Entropy Protocols"

    - by Maus
    This question might be more suited to math.stackexchange.com, but here goes: Their Version Reconciliation takes two parts-- first the exchange of digests, and then an exchange of updates. I'll first paraphrase the paper's description of each step. To exchange digests, two peers send one another a set of pairs-- (peer, max_version) for each peer in the network, and then each one responds with a set of deltas. The deltas look like: (peer, key, value, version), for all tuples for which peer's state maps the key to the given value and version, and the version number is greater than the maximum version number peer has seen. This seems to require that each node remember the state of each other node, and the highest version number and ID each node has seen. Question Why must we iterate through all peers to exchange information between p and q?

  • How to control gnome-terminal from Python scrypt?

    - by user936401
    I am developing an application in PyGtk, and would like to launch a gnome-terminal and output commands to it. My user should then be able to modify the command, or maybe ignore using the up arrow ... etc. I have been able to launch a terminal, but can't work out how to send commands. This is how my application starts: class App(Gtk.Window): def __init__(self): Gtk.Window.__init__(self) process=subprocess.Popen(["gnome-terminal", "--class=App", "--name=app"], shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE) response,error=process.communicate()

  • Access Control Service V2 and Facebook Integration

    - by Your DisplayName here!
    I haven’t been blogging about ACS2 in the past because it was not released and I was kinda busy with other stuff. Needless to say I spent quite some time with ACS2 already (both in customer situations as well as in the classroom and at conferences). ACS2 rocks! It’s IMHO the most interesting and useful (and most unique) part of the whole Azure offering! For my talk at VSLive yesterday, I played a little with the Facebook integration. See Steve’s post on the general setup. One claim that you get back from Facebook is an access token. This token can be used to directly talk to Facebook and query additional properties about the user. Which properties you have access to depends on which authorization your Facebook app requests. You can specify this in the identity provider registration page for Facebook in ACS2. In my example I added access to the home town property of the user. Once you have the access token from ACS you can use e.g. the Facebook SDK from Codeplex (also available via NuGet) to talk to the Facebook API. In my sample I used the WIF ClaimsAuthenticationManager to add the additional home town claim. This is not necessarily how you would do it in a “real” app. Depends ;) The code looks like this (sample code!): public class ClaimsTransformer : ClaimsAuthenticationManager {     public override IClaimsPrincipal Authenticate( string resourceName, IClaimsPrincipal incomingPrincipal)     {         if (!incomingPrincipal.Identity.IsAuthenticated)         {             return base.Authenticate(resourceName, incomingPrincipal);         }         string accessToken;         if (incomingPrincipal.TryGetClaimValue( "http://www.facebook.com/claims/AccessToken", out accessToken))         {             try             {                 var home = GetFacebookHometown(accessToken);                 if (!string.IsNullOrWhiteSpace(home))                 {                     incomingPrincipal.Identities[0].Claims.Add( new Claim("http://www.facebook.com/claims/HomeTown", home));                 }             }             catch { }         }         return incomingPrincipal;     }      private string GetFacebookHometown(string token)     {         var client = new FacebookClient(token);         dynamic parameters = new ExpandoObject();         parameters.fields = "hometown";         dynamic result = client.Get("me", parameters);         return result.hometown.name;     } }

  • Detecting right-click on XAML GridView control item

    - by mbrit
    Leaving aside why you would ever want to do this in a touch-centric world, here's how you tell if the right-mouse button has been clicked on a GridView in XAML/WinRT/Metro-style. You have to retrieve a point relative to the UI element you're in, and then query its properties. void itemGridView_PointerPressed(object sender, PointerRoutedEventArgs e) { if (e.GetCurrentPoint(this).Properties.IsRightButtonPressed) { this.BottomAppBar.IsOpen = true; } } (The reason why you might want to do this can be explained by looking at any of the built-in Win8 apps. You can right-click any of the items on any list to bring up a context-sensitive AppBar.)

  • Using Queries with Coherence Read-Through Caches

    - by jpurdy
    Applications that rely on partial caches of databases, and use read-through to maintain those caches, have some trade-offs if queries are required. Coherence does not support push-down queries, so queries will apply only to data that currently exists in the cache. This is technically consistent with "read committed" semantics, but the potential absence of data may make the results so unintuitive as to be useless for most use cases (depending on how much of the database is held in cache). Alternatively, the application itself may manually "push down" queries to the database, either retrieving results equivalent to querying the cache directly, or may query the database for a key set and read the values from the cache (relying on read-through to handle any missing values). Obviously, if the result set is too large, reading through the cache may cause significant thrashing. It's also worth pointing out that if the cache is asynchronously synchronized with the database (perhaps via database change listener), that an application may commit a transaction to the database, then generate a key set from the database via a query, then read cache entries through the cache, possibly resulting in a race condition where the application sees older data than it had previously committed. In theory this is not problematic but in practice it is very unintuitive. For this reason it often makes sense to invalidate the cache when updating the database, forcing the next read-through to update the cache.

  • Allow non-sudo group to control Upstart job

    - by Angle O'Saxon
    I'm trying to set up an Upstart job to run on system startup, and that can also be started/stopped by members of a group other than sudo. With a previous version, I usedupdate-rc.d and scripts stored in /etc/init.d/ to get this working by adding %Group ALL = NOPASSWD: /etc/init.d/scriptname to my sudoers file, but I can't seem to get an equivalent working for Upstart. I tried adding %Group ALL = NOPASSWD: /sbin/initctl start jobname to the sudoers file, but trying to run the command start jobname produces this error: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.21" (uid=1000 pid=5148 comm="start jobname " interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") As near as I can tell, that's a complaint about how my user account isn't given the power to send 'Start' messages in the D-Bus config file for Upstart. I haven't been able to actually find any information on how to edit that file to give a group permission to access a specific service--does such an option exist? Is there a way to edit the Sudoers file so I can run the job without editing the config file? Am I better off just sticking with the previous version?

  • Structuring Access Control In Hierarchical Object Graph

    - by SB2055
    I have a Folder entity that can be Moderated by users. Folders can contain other folders. So I may have a structure like this: Folder 1 Folder 2 Folder 3 Folder 4 I have to decide how to implement Moderation for this entity. I've come up with two options: Option 1 When the user is given moderation privileges to Folder 1, define a moderator relationship between Folder 1 and User 1. No other relationships are added to the db. To determine if the user can moderate Folder 3, I check and see if User 1 is the moderator of any parent folders. This seems to alleviate some of the complexity of handling updates / moved entities / additions under Folder 1 after the relationship has been defined, and reverting the relationship means I only have to deal with one entity. Option 2 When the user is given moderation privileges to Folder 1, define a new relationship between User 1 and Folder 1, and all child entities down to the grandest of grandchildren when the relationship is created, and if it's ever removed, iterate back down the graph to remove the relationship. If I add something under Folder 2 after this relationship has been made, I just copy all Moderators into the new Entity. But when I need to show only the top-level Folders that a user is Moderating, I need to query all folders that have a parent folder that the user does not moderate, as opposed to option 1, where I just query any items that the user is moderating. Thoughts I think it comes down to determining if users will be querying for all parent items more than they'll be querying child items... if so, then option 1 seems better. But I'm not sure. Is either approach better than the other? Why? Or is there another approach that's better than both? I'm using Entity Framework in case it matters.
