  • lightweight publish/subscribe framework in java

    - by mdma
    Is there a good lightweight framework for java that provides the publish/subscribe pattern? Some ideal features Support for generics Registration of multiple subscribers to a publisher API primarily interfaces and some useful implementations purely in-memory, persistence and transaction guarantees not required. I know about JMS but that is overkill for my need. The publish/subscribed data are the result of scans of a file system, with scan results being fed to another component for processing, which are then processed before being fed to another and so on.

  • Why Kiln is based on Mercurial, and not other (D)VCS

    - by Jakub Narebski
    What were the reason for chosing Mercurial as a basis of FogCreek Kiln, a source control management system with tightly integrated code review, and FogBugz integration? Why Mercurial, and not other (distributed) version control system, like Bazaar, Git or Monotone, or creating own version control system like Fossil (distributed software configuration management, including bug tracking and wiki) did? What were features that make FogCreek choose Mercurial as Kiln engine?

  • scroll/search JList when user starts typing

    - by alex
    I would like to implement one of the fanciest features I every now and then. I would like to allow a user to click on a JList and if words are typed, do a query and advance the caret to the next match (prefix). Is there and example of such an implementation in Java somewhere? I'm thinking a combination of key listeners, getNextMatch() and setSelectValue().

  • [Zend YouTubeAPP] failed to upgrade a token

    - by kwokwai
    Hi all, I was testing Zend Gdata 1.10.1 in my localhost. I downloaded Zend Gdate from this link: http://framework.zend.com/download/webservices Inside the Zend Gdata zip file, there was a folder called demos. I extracted it and used the YouTudeVideoApp to upload a sample video to Youtube. But every time after I logged into Youtube, before it redirected me to my localhost, I received a warning message like this warning message: localhost: This website is registered with Google to make authorization requests, but has not been configured to send requests securely. We recommend that you continue the process only if you trust the following destination: localhost:8080/youtube/operations.php So I googled on how to resolve the problem of getting this warning message when I saw some people suggesed changing the value of $secure to True in operation.php. Here is the script mentioned: function generateAuthSubRequestLink($nextUrl = null) { $scope = 'http://gdata.youtube.com'; $secure = true; $session = true; if (!$nextUrl) { generateUrlInformation(); $nextUrl = $_SESSION['operationsUrl']; } $url = Zend_Gdata_AuthSub::getAuthSubTokenUri($nextUrl, $scope, $secure, $session); echo '<a href="' . $url . '"><strong>Click here to authenticate with YouTube</strong></a>'; } After I altered the value of $secure to True, I found that the warning message changed to this: localhost: Registered, secure. This website is registered with Google to make authorization requests The new warning message is somehow shorter and looks better than the previous warning message. But once I pressed the Allow Access button, it turned out to be this: ERROR - Token upgrade for CI3M6_Q3EOGkxoL-___wEYjffToQQ failed : Token upgrade failed. Reason: Invalid AuthSub header. Error 401 ERROR - Unknown search type - '' I don't know why this happened. Could you help me solve the problem please?

  • getting maps to accept a dynamically generated KML file?

    - by arc
    Hi. I have a button that launches the google maps app on my device via an intent. I want to be able to pass it a php page that generates a KML file. I have done this on a website before using the googlemaps api in JS - but it doesn't seem to work on Android. My php file is as follows; <?php echo '<kml xmlns="http://www.google.com/earth/kml/2">'; echo '<Placemark>'; echo '<name>Google Inc.</name>'; echo '<description>1600 Amphitheatre Parkway, Mountain View, CA 94043</description>'; echo '<Point>'; echo '<coordinates>-122.0841430, 37.4219720, 0</coordinates>'; echo '</Point>'; echo '</Placemark>'; echo '</kml>'; ?> Launching with: final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse("geo:0,0?q=http://website.com/kml_gen.php")); startActivity(myIntent); It launches maps, finds the file - but won't display it 'because it contains errors'. Is this just not possible, or are there other ways to construct the intent that might work?

  • Updating a local sqlite db that is used for local metadata & caching from an service?

    - by Pharaun
    I've searched through the site and haven't found a question/answer that quite answer my question, the closest one I found was: Syncing objects between two disparate systems best approach. Anyway to begun, because there is no RSS feeds available, I'm screen scrapping a webpage, hence it does a fetch then it goes through the webpage to scrap out all of the information that I'm interested in and dumps that information into a sqlite database so that I can query the information at my leisure without doing repeat fetching from the website. However I'm also storing various metadata on the data itself that is stored in the sqlite db, such as: have I looked at the data, is the data new/old, bookmark to a chunk of data (Think of it as a collection of unrelated data, and the bookmark is just a pointer to where I am in processing/reading of the said data). So right now my current problem is trying to figure out how to update the local sqlite database with new data and/or changed data from the website in a manner that is effective and straightforward. Here's my current idea: Download the page itself Create a temporary table for the parsed data to go into Do a comparison between the official and the temporary table and copy updates and/or new information to the official table This process seems kind of complicated because I would have to figure out how to determine if the data in the temporary table is new, updated, or unchanged. So I am wondering if there isn't a better approach or if anyone has any suggestion on how to architecture/structure such system?

  • Content management system similar to StackOverflow.com

    - by Ghostrider
    I'm looking content management system that would have features similar to stackoverflow: Users can ask and answer/questions. Users can search within existing threads. The system is access controlled - so some users can be readers/writers/admins. Some or all QnA threads should be visible only to logged in users. So far I've mostly used wordpress as CMS but it looks like it's not well-suited for this particular task

  • Problems compiling libjingle/gtk+-2.0 for Mac OS X

    - by mindthief
    Hi All, I'm trying to compile libjingle on Mac OSX Snow Leopard. The INSTALL file said to './configure', 'make' and 'make install', as usual. But make fails for me. Initially it gave some messages indicating that I didn't have pkg-config installed (I guess OSX doesn't come with it installed?), so I downloaded pkg-config from http://pkgconfig.freedesktop.org/releases/ Now I get this message: Package gtk+-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk+-2.0' found I tried to install gtk by using the script at SourceForge: http://sourceforge.net/projects/gtk-osx/ (this is the website pointed to by the gtk website) Running the script didn't really seem to do anything, here is the output: $./gtk-osx-build-setup.sh Checking out jhbuild (2.27.3) from git... From git://git.gnome.org/jhbuild * tag 2.27.3 -> FETCH_HEAD Installing jhbuild... Installing jhbuild configuration... Installing gtk-osx moduleset files... Done. $ And I still get that error message about "Package gtk+-2.0 not found" while make-ing libjingle. Help will be appreciated, thanks!

  • pure as3 benefits to compiling with flex4 instead of flex3?

    - by jedierikb
    If I have a pure as3 project that I have been compiling with flex3 from mxmlc, is there any reason to switch to using the mxmlc with flex4? I can use all of the flash 10 language features like Vector, 3D, etc., so that is not a reason to switch (or is there something I can't do?). But maybe there is a performance boost? Or is the exact same compiling tool and the flex code base is the only difference?

  • Trying to write up a C daemon, but don't know enough C to continue

    - by JamesM-SiteGen
    Okay, so I want this daemon to run in the background with little to no interaction. I plan to have it work with Apache, lighttpd, etc to send the session & request information to allow C to generate a website from an object DB, saving will have to be an option so, you can start the daemon with an existing DB but will not save to it unless you login to the admin area and enable, and restart the daemon. Summary of the daemon: Load a database from file. Have a function to restart the daemon. Allow Apache, lighttpd, etc to get necessary data about the request and session. A varible to allow the database to be saved to the file, otherwise it will only be stored in ram. If it is set to save back to the file, then only have neccessary data in ram. Use sql-light for the database file. Build a webpage from some template files. $(myVar) for getting variables. Get templates from a directory. ./templates/01-test/{index.html,template.css,template.js} Live version of the code and more information: http://typewith.me/YbGB1h1g1p Also I am working on a website CMS in php, but I am tring to switch to C as it is faster than php. ( php is quite fast, but the fact that making a few mySQL requests for every webpage is quite unefficent and I'm sure that it can be far better, so an object that we can recall data from in C would have to be faster ) P.S I am using Arch-Linux not MS-Windows, with the package group base-devel for the common developer tools such as make and makepgk. Edit: Oupps, forgot the question ;) Okay, so the question is, how can I turn this basic C daemon into a base to what I am attempting to do here?

  • HTML5 enabled browser for Windows Mobile 6

    - by Herberth Amaral
    I did some research on Google but I couldn't find any HTML5 browser for Windows Mobile 6. The main resource I'm looking for in HTML5 is WebDatabase and/or localStorage. With a little research I found Iris (http://www.freewarepocketpc.net/ppc-download-iris-browser.html), a Webkit based browser with some HTML5 features, but localStorage and Web Database doesn't work on it. Does anyone know any browser with storage capability for Windows Mobile 6?

  • WCF service consuming passively issued SAML token

    - by Neillyboy
    What is the best way to pass an existing SAML token from a website already authenticated via a passive STS? We have built an Identity Provider which is issuing passive claims to the website for authentication. We have this working. Now we would like to add some WCF services into the mix - calling them from the context of the already authenticated web application. Ideally we would just like to pass the SAML token on without doing anything to it (i.e. adding new claims / re-signing). All of the examples I have seen require the ActAs sts implementation - but is this really necessary? This seems a bit bloated for what we want to achieve. I would have thought a simple implementation passing the bootstrap token into the channel - using the CreateChannelActingAs or CreateChannelWithIssuedToken mechanism (and setting ChannelFactory.Credentials.SupportInteractive = false) to call the WCF service with the correct binding (what would that be?) would have been enough. We are using the Fabrikam example code as reference, but as I say, think the ActAs functionality here is overkill for what we are trying to achieve.

  • PHP .htaccess issue, specific/dynamic keywords

    - by Kunal
    Here goes my .htaccess file's content. Options +FollowSymLinks RewriteEngine On RewriteRule ^online-products$ products.php?type=online RewriteRule ^land-products$ products.php?type=land RewriteRule ^payment-methods$ payment-methods.php RewriteRule ^withdrawal-methods$ withdrawal-methods.php RewriteRule ^deposit-methods$ deposit-methods.php RewriteRule ^product-bonuses$ product-bonuses.php RewriteRule ^law-and-regulations$ law-and-regulations.php RewriteRule ^product-news$ product-news.php RewriteRule ^product-games$ product-games.php RewriteRule ^no-products$ no-products.php RewriteRule ^page-not-found$ notfound.php RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^casinos/(.*)$ product.php?id=$1 RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ cms.php?link=$1 ErrorDocument 404 /notfound.php What I am trying to achive here is that the first set of rules apply to some specific keywords which should redirect to specific hard coded pages. But anything else parat from those keywords should redirect to cms.php as a parameter as you can see. But the problem is that every keyword is getting redirected to cms.php. Whereas I want any other keyword apart from which are already hard coded in .htaccess file should go cms.php. Not just every keyword. Example: www.sitename.com/online-products -> www.sitename.com/products.php?type=online www.sitename.com/about-the-website -> www.sitename.com/cms.php?id=about-the-website www.sitename.com/product-news -> www.sitename.com/product-news.php Also another issue I am facing is I can not use any keyword with space. Like "online-products" is fine, but I can't use "online products". Please help me out with your expert knowledge. Many thanks in advance for your kind help. Appreciate it.

  • How to store multiple cookies through PHP Curl

    - by Ahmad
    'SOUP.IO' is not providing any api. So Iam trying to use 'PHP Curl' to login and submit data through PHP. Iam able to login the website successfully(through cUrl), but when I try to submit data through cUrl, it gives me error of 'invalid user'. When I tried to analysed the code and website, I came to know that cUrl is getting values of only 1-2 cookies. Where as when I open the same page in FireFox, it shows me 6-7 cookies related to 'SOUP.IO'. Can some one guide me how to get all these 7 cookies values. Following cookies are getable by cUrl: soup_session_id Following cookies are shown in Firefox (not through cUrl): __qca, __utma, __utmb, __utmc, __utmz Following is my cUrl code: $cookie_file_path = getcwd()."/cookie/cookie.txt"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://www.soup.io'); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_HEADER, TRUE); curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate'); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) FirePHP/0.4'); curl_setopt($ch, CURLOPT_MAXREDIRS, 10); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $result = curl_exec($ch); curl_close($ch); print_r($result); ? Can some one guide me in this regards Thanks in advance

  • Facebook new js api and cross-domain file

    - by vondip
    Hi all, I am building a simple facebook iframe application. I've decided since the code is separate from facebook none the less, I will also create a connect website as well. In my connect website I'm trying to figure out the following: I am using facebook's new api and I am calling the init function. I can't seem to figure out where I combine my cross-domain file. There's no mention of it in their documentation either. http://developers.facebook.com/docs/reference/javascript/FB.init I am referring to these lines of code: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({appId: 'your app id', status: true, cookie: true, xfbml: true}); }; (function() { var e = document.createElement('script'); e.async = true; e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; document.getElementById('fb-root').appendChild(e); }()); </script>

  • How to process AJAX requests more securely in PHP?

    - by animuson
    Ok, so I want to send AJAX requests to my website from my Flash games to process data, but I don't want people downloading them, decompiling them, then sending fake requests to be processed, so I'm trying to figure out the most secure way to process in the PHP files. My first idea was to use Apache's built in Authorization module to require a username and password to access the pages on a separate subdomain of my website, but then you'd have to include that username and password in the AJAX request anyway so that seems kind of pointless to even try. My current option looks pretty promising but I want to make sure it will work. Basically it just checks the IP address being sent using REMOTE_ADDR to make sure it's the IP address that my server runs on. <? $allowed = new Array("64.120.211.89", "64.120.211.90"); if (!in_array($_SERVER['REMOTE_ADDR'], $allowed)) header("HTTP/1.1 403 Forbidden"); ?> Both of those IP addresses point to my server. Things I'm worried about: 1) If I send a request from Flash/ActionScript, will that affect the IP address in any way? 2) Is it possible for malicious users to change the IP address that is being sent with REMOTE_ADDR to one of my IP addresses? Any other ways you would suggest that might be more secure?

  • How do I track down sporadic ASP.NET performance problems in a production environment?

    - by Steve Wortham
    I've had sporadic performance problems with my website for awhile now. 90% of the time the site is very fast. But occasionally it is just really, really slow. I mean like 5-10 seconds load time kind of slow. I thought I had narrowed it down to the server I was on so I migrated everything to a new dedicated server from a completely different web hosting company. But the problems continue. I guess what I'm looking for is a good tool that'll help me track down the problem, because it's clearly not the hardware. I'd like to be able to log certain events in my ASP.NET code and have that same logger also track server performance/resources at the time. If I can then look back at the logs then I can see what exactly my website was doing at the time of extreme slowness. Is there a .NET logging system that'll allow me to make calls into it with code while simultaneously tracking performance? What would you recommend?
