  • In Ubuntu Linux, how do I list packages installed from the “universe” repository?

    - by Nate
    On an Ubuntu 10.04 LTS server, I want to list installed packages and see what repository they come from. It’s easy to list installed packages, but it does not include the name of the repository (such as “main” or “universe”). And this information isn’t in /var/lib/dpkg/status, so dpkg-query doesn’t show it either. I want to get a list of “unsupported” software—that is, software that doesn’t come from the “main” repository, and for which Ubuntu does not guarantee security updates. Note: This is a server. It does not have X, GNOME or KDE installed.

  • Applications on my laptop crashees every 10-20 minutes [closed]

    - by user1731110
    In my windows 7 home premium, several of my application crashes after some minutes even wehn I am not touching system. For example I have outlook 2007, that works fine, but suddenly crashes. The same about visual studio 2012. It is also crashes after some minute no matter if I am working on a project or I am not touching it. the same behaviour is there, for other applications (skype, oovoo and ...). I use Microsoft security essential and there is no virus on my system. I also checked my system with Sophos anti root kit and there is no root kit there. What would be the problem?

  • Mysql loses its root password

    - by RubyDev
    I am having a strange problem, my mysql loses/resets the root password automatically. By which I mean that it resets it to none. It has happened twice this month. I am worried that it can be a security issue as data is open waiting only for someone trying no password! Here is the version: mysql --version mysql Ver 14.14 Distrib 5.1.56, for redhat-linux-gnu (i386) using readline 5.1 Any help would be appreciated. Update: Output of select user, host, password from mysql.user; how it looks after the password got reset | root | localhost | | root | 127.0.0.1 | | | localhost | | | admin | localhost | ################################# | (I have removed the actual output with #) So all the passwords are blank, except for for another user named 'admin'

  • Is there good FAT driver for FUSE? (Lightweight, not mountlo)

    - by Vi.
    FUSE filesystem list show some FuseFat and FatFuse. Both are old, FatFuse is read-only , FuseFat is non-buildable and probably depends on glib. Now I'm using mountlo for the task (mounting USB drives in generic way without root access or suid things (except of fusermount itself)), but it looks too big for such task. Using FUSE to mount external storage devices is good both for security and for flexibility reason: the kernel sees only block reads and writes while actual code that deals with filesystem details runs with user privileges, allowing user to use custom filesystems and preventing from kernel filesystem exploits. Is there good vfat FUSE driver?

  • IIS 6.0 :: SSL certificate install :: issue

    - by BSI Support
    Certificate request process works fine. Once the certificate is received from VeriSign, the installation process also works fine (no errors.) However, once installed, the new certificate is not "assigned." Meaning, when I view the IIS instance security properties, it still shows the previous certificate start & end dates. Thoughts? Windows 2003, Web Edition. I have 3 other Win2003WE machines, configured nearly the same, and do not have this problem.

  • How can I exclude a file in a folder from basic auth (regex help)?

    - by simon180
    Hi I have a folder on my site which contains admin files and I've added basic auth following a little unwanted attention. This works fine however a couple of the admin functions won't work through basic auth as they handle file uploads and so I want to exclude these files from the auth. It shouldn't have any security implications as any rogue user wouldn't be able to access the pages that could create a session to use these functions. I am using the following basic code to exclude a file: <FilesMatch "(index.php\/myadminfolder\/myurl\/myaction/someotherstuff?)$"> Satisfy Any Order allow,deny Allow from all Deny from none </FilesMatch> The URL exclusion is not working. The URL to exclude is in the form: index.php/directory/subdirectory/action/uniqueid/blah What is the correct URL string to add to FilesMatch to exclude any files that start with the pattern of index.php/directory/subdirectory/action - regardless of what comes after action? Thanks Simon

  • "Clear Text Credential Access Enabled" field

    - by Dave
    Searching for answers about the "Clear Text Credential Access Enabled" field, I found a question on an oracle forum that was my exactly what I was trying to find out. Thinking that my answer would soon be found, I happily click on the link only to find zero replies. All hope was lost. I am posting the question here, hoping that someone on this site will know the answer. Can somebody please explain the usage of "Clear Text Credential Access Enabled" checkbox under "-Security-Advanced tab for Weblogic 11g? What is the difference if we set or unset this flag? If I dont set this flag I get an exception like "Access to sensitive attribute in clear text is not allowed due to the setting of ClearTextCredentialAccessEnabled attribute in SecurityConfigurationMBean" when I try to set a value for the "Credential" field. But what should be the value for "Credential" field if I dont set the "Clear Text Credential Access Enabled"flag?

  • What's the best practice for taking MySQL dump, encrypting it and then pushing to s3?

    - by HalogenCreative
    This current project requires that the DB be dumped, encrypted and pushed to s3. I'm wondering what might be some "best practices" for such a task. As of now I'm using a pretty straight ahead method but would like to have some better ideas where security is concerned. Here is the start of my script: mysqldump -u root --password="lepass" --all-databases --single-transaction > db.backup.sql tar -c db.backup.sql | openssl des3 -salt --passphrase foopass > db.backup.tarfile s3put backup/db.backup.tarfile db.backup.tarfile # Let's pull it down again and untar it for kicks s3get surgeryflow-backup/db/db.backup.tarfile db.backup.tarfile cat db.backup.tarfile | openssl des3 -d -salt --passphrase foopass |tar -xvj Obviously the problem is that this script everything an attacker would need to raise hell. Any thoughts, critiques and suggestions for this task will be appreciated.

  • Is there any IP which refers to the internet?

    - by victorferreira
    Hello, guys, good morning. 127.0.0.1 is the local IP, isnt it? Is there a IP that I can use in order to refer to the any user in the internet? The thing is: i want to block a specific file to be accessed by the internet using IIS6. but i doesnt show me a clear way to do this. But i can define some security rules, for example: give IP restrictions for some file. So, i can deny for everybody (using that IP i am asking about) and allow for the internal IP. any suggestions?

  • Local System Account in Windows Server 2008

    - by user31676
    Hi, Have the security persmission or anything else changed for the Local System Account in Windows Server 2008 versus Windows Server 2003? We have a service, that logs on as the Local System Account, that creates folders on the server (same server as the service is installed). It works perfectly when installed on Windows Server 2003 however when installed in Windows Server 2008 the folders do not get created. It appears as if the Local System Account does not have persmission to create the folders. Any insight that anyone can provide is greatly appreciated. Thanks, Scott

  • Ubuntu server 9.10 freezes up after ~10 minutes - unconventional

    - by L33tCh
    There is a topic by essentially the same name, but my answer leads to another question which I would like answered so... My case is as follows: I connect through SSH to my server... no problems for many months on Ubuntu Server 9.04. Eventually I decided to updgrade and straight away I get the 10 minutes freeze problem. I went through all the possible fixes (many can be found here but my quick fix, the only that worked, leaves me with no real answer as to why and how to properly correct it... As ridiculous as it sounds... while I leave a keyboard plugged in... it runs without flaw. Can anyone make sense of this? For the sake of completeness, (although none of the following made any difference upon subsequent completion), some of the permanent changes I have made while trying to correct the issue are: replacing samba config file with 9.04 backup, booting with noapic and modifying sysctl.conf, just uncommenting additional settings for enhanced security.

  • Windows 7 100% Memory Usage (without any process listed as using that much memory)

    - by Paul Tarjan
    When I plug my external USB 2TB hard drive into my windows 7 box, my RAM usage climbs up to all 4 Gigs (but in task manager it shows that all process are small) and the hard drive is churning like crazy. My CPU is only about 20% utilized All I can think of is there is a Virus scanner or an indexer running like crazy. I've tried to kill all virus scanners (AVG and Windows Security Essentials) and it still keeps going. My computer is completely unusable as everything is constantly swapping. I've tried leaving it on for 2 days now and it still hasn't finished whatever it was doing. Any ideas?

  • Seperating paid and free users on SQl Server 2008 R2

    - by Alex
    Right now we have hundreds of "free demo" trial users on the same db server/database with our paid mission critical users. I see this as both a security risk and a load issue. I have also seen cases where demo users run large reports and crash the server.. Does it make sense to separate these users into separate databases on SQL? Rather than just have one DB for all users? My thinking is so one group of users has no effect on the other? Can one group still pose a risk if we do this? I plan to have them on separate web servers also (windows 2008 r2, iis 7, .net 4.0)

  • Is it normal that Software installs in Admin user folder?

    - by RoToRa
    I've got a new computer with Windows 7, which I'm using for the first time. For security I decided to create a standard user for everyday work instead of using an admin account. However when I install programs logged in as the standard user (such as Aptana right now) they always try to install in the admin's user folder (C:\Users\Admin\AppData...). I'd expect the programs to install to the standard user's folder or Progran Files as in XP. This also leads to that I need to grant admin rights whenever I start such a program. Of course I could just change the installation path every time, but I find this behavior strange. Ist it normal, or did I somehow mess up the Windows 7 installation?

  • What is the equivalent of domain admin on Sharepoint 2010?

    - by user54266
    I have to support Sharepoint on a daily basis but do not have the equivalent of domain access so I'm constantly having to ask the guy in charge of Sharepoint to add me to a new security group to complete my task. Rather than having to bug him all the time (he is only somewhat technical) it would be easier to simply have the equivalent of domain admin access for Sharepoint (I'm a sys admin and have domain admin access already but this doesn't seem to carry over to FOSS). What is the equivalent of domain admin access on Sharepoint 2010? Thanks in advance.

  • Automate the process of looking for CVE (new vulnerabilities) related to our infrastructure

    - by skinp
    Is there any service available where you simply list the services, programs and versions you use, and when some CVE comes out about it, you automatically get alerted? Also, is there any other place to look for this kind of information. Do some people release security vulnerabilities to other places than CVE? So in general, how do you guys keep up to date with what might be vulnerable in your infrastructure? Edit: Since I've been asked, we are a Unix shop with mostly Red Hat and some HP-UX. I would still prefer a high level solution which are OS independent. What happens if we use software versions which are not in the official repositories of Red Hat/HP/... or simply not supported by them.

  • I missed allowing ".NET Runtime Optimization Service" while installing a game — could there be any problems?

    - by MDLss
    I'm using ESET Smart Security 4 on Windows 7. I selected Interactive Mode so it asks me when something needs to connect to my PC. So when I was installing a game named League of Legends, I was away from my computer. When I came back, I saw that the download was finished but ESET was asking whether to allow .NET Runtime Optimization Service to connect my computer using port 80 TCP. So I selected Allow but It was too late because the download was already finished. I can play the game, but could it be bugged or broken or something?

  • Administrators: People interaction and Working hours?

    - by sanksjaya
    Do admins get to meet a lot of new people on a daily basis at work? And what kind of people domain do they interact with? Secondly, I've had this myth for a long time that unlike programmers, Network/System/Security Admins get locked-up in a den and juiced up late nights and early mornings. Most of the time they had to slip out of work without being noticed. How true and often does this happen for you? I understand there is no specific answer to this question as it depends on the type of working organization. But just looking out for answers from your experience. Thanks :) Clarification: I've had the question posted on to stackoverflow and they closed it. So I posted it here.

  • How to Upgrade Your Netbook to Windows 7 Home Premium

    - by Matthew Guay
    Would you like more features and flash in Windows on your netbook?  Here’s how you can easily upgrade your netbook to Windows 7 Home Premium the easy way. Most new netbooks today ship with Windows 7 Starter, which is the cheapest edition of Windows 7.  It is fine for many computing tasks, and will run all your favorite programs great, but it lacks many customization, multimedia, and business features found in higher editions.  Here we’ll show you how you can quickly upgrade your netbook to more full-featured edition of Windows 7 using Windows Anytime Upgrade.  Also, if you want to upgrade your laptop or desktop to another edition of Windows 7, say Professional, you can follow these same steps to upgrade it, too. Please note: This is only for computers already running Windows 7.  If your netbook is running XP or Vista, you will have to run a traditional upgrade to install Windows 7. Upgrade Advisor First, let’s make sure your netbook can support the extra features, such as Aero Glass, in Windows 7 Home Premium.  Most modern netbooks that ship with Windows 7 Starter can run the advanced features in Windows 7 Home Premium, but let’s check just in case.  Download the Windows 7 Upgrade Advisor (link below), and install as normal. Once it’s installed, run it and click Start Check.   Make sure you’re connected to the internet before you run the check, or otherwise you may see this error message.  If you see it, click Ok and then connect to the internet and start the check again. It will now scan all of your programs and hardware to make sure they’re compatible with Windows 7.  Since you’re already running Windows 7 Starter, it will also tell you if your computer will support the features in other editions of Windows 7. After a few moments, the Upgrade Advisor will show you want it found.  Here we see that our netbook, a Samsung N150, can be upgraded to Windows 7 Home Premium, Professional, or Ultimate. We also see that we had one issue, but this was because a driver we had installed was not recognized.  Click “See all system requirements” to see what your netbook can do with the new edition. This shows you which of the requirements, including support for Windows Aero, your netbook meets.  Here our netbook supports Aero, so we’re ready to go upgrade. For more, check out our article on how to make sure your computer can run Windows 7 with Upgrade Advisor. Upgrade with Anytime Upgrade Now, we’re ready to upgrade our netbook to Windows 7 Home Premium.  Enter “Anytime Upgrade” in the Start menu search,and select Windows Anytime Upgrade. Windows Anytime Upgrade lets you upgrade using product key you already have or one you purchase during the upgrade process.  And, it installs without any downloads or Windows disks, so it works great even for netbooks without DVD drives. Anytime Upgrades are cheaper than a standard upgrade, and for a limited time, select retailers in the US are offering Anytime Upgrades to Windows 7 Home Premium for only $49.99 if purchased with a new netbook.  If you already have a netbook running Windows 7 Starter, you can either purchase an Anytime Upgrade package at a retail store or purchase a key online during the upgrade process for $79.95.  Or, if you have a standard Windows 7 product key (full or upgrade), you can use it in Anytime upgrade.  This is especially nice if you can purchase Windows 7 cheaper through your school, university, or office. Purchase an upgrade online To purchase an upgrade online, click “Go online to choose the edition of Windows 7 that’s best for you”.   Here you can see a comparison of the features of each edition of Windows 7.  Note that you can upgrade to either Home Premium, Professional, or Ultimate.  We chose home Premium because it has most of the features that home users want, including Media Center and Aero Glass effects.  Also note that the price of each upgrade is cheaper than the respective upgrade from Windows XP or Vista.  Click buy under the edition you want.   Enter your billing information, then your payment information.  Once you confirm your purchase, you will directly be taken to the Upgrade screen.  Make sure to save your receipt, as you will need the product key if you ever need to reinstall Windows on your computer. Upgrade with an existing product key If you purchased an Anytime Upgrade kit from a retailer, or already have a Full or Upgrade key for another edition of Windows 7, choose “Enter an upgrade key”. Enter your product key, and click Next.  If you purchased an Anytime Upgrade kit, the product key will be located on the inside of the case on a yellow sticker. The key will be verified as a valid key, and Anytime Upgrade will automatically choose the correct edition of Windows 7 based on your product key.  Click Next when this is finished. Continuing the Upgrade process Whether you entered a key or purchased a key online, the process is the same from here on.  Click “I accept” to accept the license agreement. Now, you’re ready to install your upgrade.  Make sure to save all open files and close any programs, and then click Upgrade. The upgrade only takes about 10 minutes in our experience but your mileage may vary.  Any available Microsoft updates, including ones for Office, Security Essentials, and other products, will be installed before the upgrade takes place. After a couple minutes, your computer will automatically reboot and finish the installation.  It will then reboot once more, and your computer will be ready to use!  Welcome to your new edition of Windows 7! Here’s a before and after shot of our desktop.  When you do an Anytime Upgrade, all of your programs, files, and settings will be just as they were before you upgraded.  The only change we noticed was that our pinned taskbar icons were slightly rearranged to the default order of Internet Explorer, Explorer, and Media Player.  Here’s a shot of our desktop before the upgrade.  Notice that all of our pinned programs and desktop icons are still there, as well as our taskbar customization (we are using small icons on the taskbar instead of the default large icons). Before, with the Windows 7 Starter background and the Aero Basic theme: And after, with Aero Glass and the more colorful default Windows 7 background.   All of the features of Windows 7 Home Premium are now ready to use.  The Aero theme was activate by default, but you can now customize your netbook theme, background, and more with the Personalization pane.  To open it, right-click on your desktop and select Personalize. You can also now use Windows Media Center, and can play-back DVD movies using an external drive. One of our favorite tools, the Snipping Tool, is also now available for easy screenshots and clips. Activating you new edition of Windows 7 You will still need to activate your new edition of Windows 7.  To do this right away, open the start menu, right-click on Computer, and select Properties.   Scroll to the bottom, and click “Activate Windows Now”. Make sure you’re connected to the internet, and then select “Activate Windows online now”. Activation may take a few minutes, depending on your internet connection speed. When it is done, the Activation wizard will let you know that Windows is activated and genuine.  Your upgrade is all finished! Conclusion Windows Anytime Upgrade makes it easy, and somewhat cheaper, to upgrade to another edition of Windows 7.  It’s useful for desktop and laptop owners who want to upgrade to Professional or Ultimate, but many more netbook owners will want to upgrade from Starter to Home Premium or another edition.  Links Download the Windows 7 Upgrade Advisor Windows Team Blog: Anytime Upgrade Special with new PC purchase Similar Articles Productive Geek Tips How To Upgrade from Vista to Windows 7 Home Premium EditionAnother Blog You Should Subscribe ToMysticgeek Blog: Turn Vista Home Premium Into Ultimate (Part 3) – Shadow CopyUpgrade Ubuntu from Breezy to DapperHow to Upgrade the Windows 7 RC to RTM (Final Release) TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 Get Your Delicious Bookmarks In Firefox’s Awesome Bar Manage Photos Across Different Social Sites With Dropico Test Drive Windows 7 Online Download Wallpapers From National Geographic Site Spyware Blaster v4.3 Yes, it’s Patch Tuesday

  • Netflix, jQuery, JSONP, and OData

    - by Stephen Walther
    At the last MIX conference, Netflix announced that they are exposing their catalog of movie information using the OData protocol. This is great news! This means that you can take advantage of all of the advanced OData querying features against a live database of Netflix movies. In this blog entry, I’ll demonstrate how you can use Netflix, jQuery, JSONP, and OData to create a simple movie lookup form. The form enables you to enter a movie title, or part of a movie title, and display a list of matching movies. For example, Figure 1 illustrates the movies displayed when you enter the value robot into the lookup form.   Using the Netflix OData Catalog API You can learn about the Netflix OData Catalog API at the following website: http://developer.netflix.com/docs/oData_Catalog The nice thing about this website is that it provides plenty of samples. It also has a good general reference for OData. For example, the website includes a list of OData filter operators and functions. The Netflix Catalog API exposes 4 top-level resources: Titles – A database of Movie information including interesting movie properties such as synopsis, BoxArt, and Cast. People – A database of people information including interesting information such as Awards, TitlesDirected, and TitlesActedIn. Languages – Enables you to get title information in different languages. Genres – Enables you to get title information for specific movie genres. OData is REST based. This means that you can perform queries by putting together the right URL. For example, if you want to get a list of the movies that were released after 2010 and that had an average rating greater than 4 then you can enter the following URL in the address bar of your browser: http://odata.netflix.com/Catalog/Titles?$filter=ReleaseYear gt 2010&AverageRating gt 4 Entering this URL returns the movies in Figure 2. Creating the Movie Lookup Form The complete code for the Movie Lookup form is contained in Listing 1. Listing 1 – MovieLookup.htm <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Netflix with jQuery</title> <style type="text/css"> #movieTemplateContainer div { width:400px; padding: 10px; margin: 10px; border: black solid 1px; } </style> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="App_Scripts/Microtemplates.js" type="text/javascript"></script> </head> <body> <label>Search Movies:</label> <input id="movieName" size="50" /> <button id="btnLookup">Lookup</button> <div id="movieTemplateContainer"></div> <script id="movieTemplate" type="text/html"> <div> <img src="<%=BoxArtSmallUrl %>" /> <strong><%=Name%></strong> <p> <%=Synopsis %> </p> </div> </script> <script type="text/javascript"> $("#btnLookup").click(function () { // Build OData query var movieName = $("#movieName").val(); var query = "http://odata.netflix.com/Catalog" // netflix base url + "/Titles" // top-level resource + "?$filter=substringof('" + escape(movieName) + "',Name)" // filter by movie name + "&$callback=callback" // jsonp request + "&$format=json"; // json request // Make JSONP call to Netflix $.ajax({ dataType: "jsonp", url: query, jsonpCallback: "callback", success: callback }); }); function callback(result) { // unwrap result var movies = result["d"]["results"]; // show movies in template var showMovie = tmpl("movieTemplate"); var html = ""; for (var i = 0; i < movies.length; i++) { // flatten movie movies[i].BoxArtSmallUrl = movies[i].BoxArt.SmallUrl; // render with template html += showMovie(movies[i]); } $("#movieTemplateContainer").html(html); } </script> </body> </html> The HTML page in Listing 1 includes two JavaScript libraries: <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="App_Scripts/Microtemplates.js" type="text/javascript"></script> The first script tag retrieves jQuery from the Microsoft Ajax CDN. You can learn more about the Microsoft Ajax CDN by visiting the following website: http://www.asp.net/ajaxLibrary/cdn.ashx The second script tag is used to reference Resig’s micro-templating library. Because I want to use a template to display each movie, I need this library: http://ejohn.org/blog/javascript-micro-templating/ When you enter a value into the Search Movies input field and click the button, the following JavaScript code is executed: // Build OData query var movieName = $("#movieName").val(); var query = "http://odata.netflix.com/Catalog" // netflix base url + "/Titles" // top-level resource + "?$filter=substringof('" + escape(movieName) + "',Name)" // filter by movie name + "&$callback=callback" // jsonp request + "&$format=json"; // json request // Make JSONP call to Netflix $.ajax({ dataType: "jsonp", url: query, jsonpCallback: "callback", success: callback }); This code Is used to build a query that will be executed against the Netflix Catalog API. For example, if you enter the search phrase King Kong then the following URL is created: http://odata.netflix.com/Catalog/Titles?$filter=substringof(‘King%20Kong’,Name)&$callback=callback&$format=json This query includes the following parameters: $filter – You assign a filter expression to this parameter to filter the movie results. $callback – You assign the name of a JavaScript callback method to this parameter. OData calls this method to return the movie results. $format – you assign either the value json or xml to this parameter to specify how the format of the movie results. Notice that all of the OData parameters -- $filter, $callback, $format -- start with a dollar sign $. The Movie Lookup form uses JSONP to retrieve data across the Internet. Because WCF Data Services supports JSONP, and Netflix uses WCF Data Services to expose movies using the OData protocol, you can use JSONP when interacting with the Netflix Catalog API. To learn more about using JSONP with OData, see Pablo Castro’s blog: http://blogs.msdn.com/pablo/archive/2009/02/25/adding-support-for-jsonp-and-url-controlled-format-to-ado-net-data-services.aspx The actual JSONP call is performed by calling the $.ajax() method. When this call successfully completes, the JavaScript callback() method is called. The callback() method looks like this: function callback(result) { // unwrap result var movies = result["d"]["results"]; // show movies in template var showMovie = tmpl("movieTemplate"); var html = ""; for (var i = 0; i < movies.length; i++) { // flatten movie movies[i].BoxArtSmallUrl = movies[i].BoxArt.SmallUrl; // render with template html += showMovie(movies[i]); } $("#movieTemplateContainer").html(html); } The movie results from Netflix are passed to the callback method. The callback method takes advantage of Resig’s micro-templating library to display each of the movie results. A template used to display each movie is passed to the tmpl() method. The movie template looks like this: <script id="movieTemplate" type="text/html"> <div> <img src="<%=BoxArtSmallUrl %>" /> <strong><%=Name%></strong> <p> <%=Synopsis %> </p> </div> </script>   This template looks like a server-side ASP.NET template. However, the template is rendered in the client (browser) instead of the server. Summary The goal of this blog entry was to demonstrate how well jQuery works with OData. We managed to use a number of interesting open-source libraries and open protocols while building the Movie Lookup form including jQuery, JSONP, JSON, and OData.
