• Introducing .NET 4.0 with Visual Studio 2010 by Alex Mackey - Book review

  - by Malisa L. Ncube

  Alex (http://simpleisbest.co.uk/) does a very good job in covering the new features of .NET 4.0 and Visual Studio 2010. His focus is on the developers that have experience in development using previous versions of Visual Studio, more specifically Visual Studio 2008.     The following are my views towards his book. 1. Scope / Coverage Even as the book is labeled as introduction, it is covers a broad spectrum of technologies, features and references that are focused into helping a developer quickly decide what to use in the new .NET framework. a. Content The content included covers as much as possible the new additions that are included in the new .NET version 4.0. He shows the Visual Studio 2010 new features and quickly shows how to extend it using Managed Extensibility Framework. Some of my favorites are parallel debugging enhancements. The author delves into JQuery, which Microsoft has decided to support. Some of the very interesting content is on the out-of-band releases including ASP.NET MVC, Windows Azure Silverlight 3 and WCF Data Services. b. What is not included? Windows Phone 7 Series. This was only talked about in the MIX10. The data may not have been available at the time of writing. Microsoft Pinpoint (Microsoft code name "Dallas") Windows Embedded development. c. Table of Contents Chapter 1: Introduction Chapter 2: Visual Studio IDE and MEF Chapter 3: Language and Dynamic Changes Chapter 4: CLR and BCL Changes Chapter 5: Parallelization and Threading Enhancements Chapter 6: Windows Workflow Foundation 4 Chapter 7: Windows Communication Foundation Chapter 8: Entity Framework Chapter 9: WCF Data Services Chapter 10: ASPNET Chapter 11: Microsoft AJAX Library Chapter 12: jQuery Chapter 13: ASPNET MVC Chapter 14: Silverlight Introduction Chapter 15: WPF 4.0 and Silverlight 3.0 Chapter 16: Windows Azure 2. Depth Avoids getting into depth on the topics presented, to present the new concepts in assumption of the developer’s existing knowledge. Code samples are on book and exist mostly as snippets and very easy to follow. There are no downloadable examples. 3. Complexity The book is written in a very simple way and easy to follow. There are no irrelevant intimidating details. So it’s a book that you can grab and never put down until you’ve finished reading the entire book. 4. References The author includes reference links to blogs, Wikis and a lot of online resources including the MSDN documentation, which is a very convenient strategy to avoid flooding the reader with details which may not be of interest to them. Most sites do not use url routing and that is really not nice. There are notes from interviews between the author and people behind the new technologies, in which they explain what some specific areas that need clarifications and what their future views are in relation to the features they are working on. 5. Target The author targets experts that want to make a transition from .NET 3.5 to 4.0. Some obvious 3.5 features have been purposely excluded from the text 6. Overrall It is evident that the author has made extensive research into the breadth of what MS is working on, in relation to .NET and Visual Studio and has also been watching the online community. What I would like to see in the next edition are some details on OData protocol, Expression Blend 4 and Embedded development and Windows Phone development. I should say I’m one of the beneficiaries of this book. Excellent work Alex.   Technorati Tags: .NET,Book-Review,Visual Studio

• Redirect all access requests to a domain and subdomain(s) except from specific IP address? [closed]

  - by Christopher

  This is a self-answered question... After much wrangling I found the magic combination of mod_rewrite rules so I'm posting here. My scenario is that I have two domains - domain1.com and domain2.com - both of which are currently serving identical content (by way of a global 301 redirect from domain1 to domain2). Domain1 was then chosen to be repurposed to be a 'portal' domain - with a corporate CMS-based site leading off from the front page, and the existing 'retail' domain (domain2) left to serve the main web site. In addition, a staging subdomain was created on domain1 in order to prepare the new corporate site without impinging on the root domain's existing operation. I contemplated just rewriting all requests to domain2 and setting up the new corporate site 'behind the scenes' without using a staging domain, but I usually use subdomains when setting up new sites. Finally, I required access to the 'actual' contents of the domains and subdomains - i.e., to not be redirected like all other visitors - in order that I can develop the new site and test it in the staging environment on the live server, as I'm not using a separate development webserver in this case. I also have another test subdomain on domain1 which needed to be preserved. The way I eventually set it up was as follows: (10.2.2.1 would be my home WAN IP) .htaccess in root of domain1 RewriteEngine On RewriteCond %{REMOTE_ADDR} !^10\.2\.2\.1 RewriteCond %{HTTP_HOST} !^staging.domain1.com$ [NC] RewriteCond %{HTTP_HOST} !^staging2.domain1.com$ [NC] RewriteRule ^(.*)$ http://domain2.com/$1 [R=301] .htaccess in staging subdomain on domain1: RewriteEngine On RewriteCond %{REMOTE_ADDR} !^10\.2\.2\.1 RewriteCond %{HTTP_HOST} ^staging.revolver.coop$ [NC] RewriteRule ^(.*)$ http://domain2.com/$1 [R=301,L] The multiple .htaccess files and multiple rulesets require more processing overhead and longer iteration as the visitor is potentially redirected twice, however I find it to be a more granular method of control as I can selectively allow more than one IP address access to individual staging subdomain(s) without automatically granting them access to everything else. It also keeps the rulesets fairly simple and easy to read. (or re-interpret, because I'm always forgetting how I put rules together!) If anybody can suggest a more efficient way of merging all these rules and conditions into just one main ruleset in the root of domain1, please post! I'm always keen to learn, this post is more my attempt to preserve this information for those who are looking to redirect entire domains for all visitors except themselves (for design/testing purposes) and not just denying specific file access for maintenance mode (there are many good examples of simple mod_rewrite rules for 'maintenance mode' style operation easily findable via Google). You can also extend the IP address detection - firstly by using wildcards ^10\.2\.2\..*: the last octet's \..* denotes the usual "." and then "zero or more arbitrary characters", signified by the .* - so you can specify specific ranges of IPs in a subnet or entire subnets if you wish. You can also use square brackets: ^10\.2\.[1-255]\.[120-140]; ^10\.2\.[1-9]?[0-9]\.; ^10\.2\.1[0-1][0-9]\. etc. The third way, if you wish to specify multiple discrete IP addresses, is to bracket them in the style of ^(1.1.1.1|2.2.2.2|3.3.3.3)$, and you can of course use square brackets to substitute octets or single digits again. NB: if you're using individual RewriteCond lines to specify multiple IPs / ranges, make sure to put [OR] at the end of each one otherwise mod_rewrite will interpret as "if IP address matches 1.1.1.1 AND if IP address matches 2.2.2.2... which is of course impossible! However as far as I'm aware this isn't necessary if you're using the ! negator to specify "and is not...". Kudos also to SE: this older question also came in useful when I was verifying my own knowledge prior to my futzing around with code. This page was helpful, as were the various other links posted below (can't hyperlink them all due to spam protection... other regex checkers are available). The AddedBytes cheat sheet's useful to pin up on your wall.

• Do NOT Change "Copy Local” project references to false, unless understand subsequences.

  - by Michael Freidgeim

  To optimize performance of visual studio build I've found multiple recommendations to change CopyLocal property for dependent dlls to false,e.g. From http://stackoverflow.com/questions/690033/best-practices-for-large-solutions-in-visual-studio-2008 CopyLocal? For sure turn this offhttp://stackoverflow.com/questions/280751/what-is-the-best-practice-for-copy-local-and-with-project-referencesAlways set the Copy Local property to false and enforce this via a custom msbuild stephttp://codebetter.com/patricksmacchia/2007/06/20/benefit-from-the-c-and-vb-net-compilers-perf/BenefitBenefitMy advice is to always set ‘Copy Local’ to falseSome time ago we've tried to change the setting to false, and found that it causes problem for deployment of top-level projects.Recently I've followed the suggestion and changed the settings for middle-level projects. It didn't cause immediate issues, but I was warned by Readify Consultant Colin Savage about possible errors during deploymentsI haven't undone the changes immediately and we found a few issues during testing.There are many scenarios, when you need to have Copy Local’ left to True.The concerns are highlighted in some stack overflow answers, but they have small number of votes.Top-level projects:  set copy local = true.First of all, it doesn't work correctly for top-level projects, i.e. executables or web sites.As pointed in the answer http://stackoverflow.com/a/6529461/52277for all the references in the one at the top set copy local = true.Alternatively you have to change output directory as it's described in http://www.simple-talk.com/dotnet/.net-framework/partitioning-your-code-base-through-.net-assemblies-and-visual-studio-projects/If you set ‘ Copy Local = false’, VS will, unless you tell it otherwise, place each assembly alone in its own .\bin\Debugdirectory. Because of this, you will need to configure VS to place assemblies together in the same directory. To do so, for each VS project, go to VS > Project Properties > Build tab > Output path, and set the Ouput path to ..\bin\Debugfor debug configuration, and ..\bin\Release for release configuration.Second-level  dependencies:  set copy local = true.Another example when copylocal =false fails on run-time, is when top level assembly doesn't directly referenced one of indirect dependencies.E..g. Top-level assembly A has reference to assembly B with copylocal =true, but assembly B has reference to assembly C with copylocal =false. Most likely assembly C will be missing on runtime and will cause errors E.g. http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1Copy local is important for deployment scenarios and tools. As a general rule you should use CopyLocal=True and http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1 Unfortunately there are some quirks and CopyLocal won't necessary work as expected for assembly references in secondary assemblies structured as shown below.MainApp.exe MyLibrary.dll ThirdPartyLibrary.dll (if in the GAC CopyLocal won't copy to MainApp bin folder)This makes xcopy deployments difficult . .Reflection called DLLs  dependencies:  set copy local = true.E.g user can see error "ISystem.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."The fix for the issue is recommended in http://stackoverflow.com/a/6200173/52277"I solved this issue by setting the Copy Local attribute of my project's references to true."In general, the problems with investigation of deployment issues may overweight the benefits of reduced build time. Setting the Copy Local to false without considering deployment issues is not a good idea.

• How do NTP Servers Manage to Stay so Accurate?

  - by Akemi Iwaya

  Many of us have had the occasional problem with our computers and other devices retaining accurate time settings, but a quick sync with an NTP server makes all well again. But if our own devices can lose accuracy, how do NTP servers manage to stay so accurate? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Photo courtesy of LEOL30 (Flickr). The Question SuperUser reader Frank Thornton wants to know how NTP servers are able to remain so accurate: I have noticed that on my servers and other machines, the clocks always drift so that they have to sync up to remain accurate. How do the NTP server clocks keep from drifting and always remain so accurate? How do the NTP servers manage to remain so accurate? The Answer SuperUser contributor Michael Kjorling has the answer for us: NTP servers rely on highly accurate clocks for precision timekeeping. A common time source for central NTP servers are atomic clocks, or GPS receivers (remember that GPS satellites have atomic clocks onboard). These clocks are defined as accurate since they provide a highly exact time reference. There is nothing magical about GPS or atomic clocks that make them tell you exactly what time it is. Because of how atomic clocks work, they are simply very good at, having once been told what time it is, keeping accurate time (since the second is defined in terms of atomic effects). In fact, it is worth noting that GPS time is distinct from the UTC that we are more used to seeing. These atomic clocks are in turn synchronized against International Atomic Time or TAI in order to not only accurately tell the passage of time, but also the time. Once you have an exact time on one system connected to a network like the Internet, it is a matter of protocol engineering enabling transfer of precise times between hosts over an unreliable network. In this regard a Stratum 2 (or farther from the actual time source) NTP server is no different from your desktop system syncing against a set of NTP servers. By the time you have a few accurate times (as obtained from NTP servers or elsewhere) and know the rate of advancement of your local clock (which is easy to determine), you can calculate your local clock’s drift rate relative to the “believed accurate” passage of time. Once locked in, this value can then be used to continuously adjust the local clock to make it report values very close to the accurate passage of time, even if the local real-time clock itself is highly inaccurate. As long as your local clock is not highly erratic, this should allow keeping accurate time for some time even if your upstream time source becomes unavailable for any reason. Some NTP client implementations (probably most ntpd daemon or system service implementations) do this, and others (like ntpd’s companion ntpdate which simply sets the clock once) do not. This is commonly referred to as a drift file because it persistently stores a measure of clock drift, but strictly speaking it does not have to be stored as a specific file on disk. In NTP, Stratum 0 is by definition an accurate time source. Stratum 1 is a system that uses a Stratum 0 time source as its time source (and is thus slightly less accurate than the Stratum 0 time source). Stratum 2 again is slightly less accurate than Stratum 1 because it is syncing its time against the Stratum 1 source and so on. In practice, this loss of accuracy is so small that it is completely negligible in all but the most extreme of cases. Have something to add to the explanation? Sound off in the comments.

• From the Tips Box: Pre-installation Prep Work Makes Service Pack Upgrades Smoother

  - by Jason Fitzpatrick

  Last month Microsoft rolled out Windows 7 Service Pack 1 and, like many SP releases, quite a few people are hanging back to see what happens. If you want to update but still error on the side of caution, reader Ron Troy  offers a step-by-step guide. Ron’s cautious approach does an excellent job minimizing the number of issues that could crop up in a Service Pack upgrade by doing a thorough job updating your driver sets and clearing out old junk before you roll out the update. Read on to see how he does it: Just wanted to pass on a suggestion for people worried about installing Service Packs.  I came up with a ‘method’ a couple years back that seems to work well. Run Windows / Microsoft Update to get all updates EXCEPT the Service Pack. Use Secunia PSI to find any other updates you need. Use CCleaner or the Windows disk cleanup tools to get rid of all the old garbage out there.  Make sure that you include old system updates. Obviously, back up anything you really care about.  An image backup can be real nice to have if things go wrong. Download the correct SP version from Microsoft.com; do not use Windows / Microsoft Update to get it.  Make sure you have the 64 bit version if that’s what you have installed on your PC. Make sure that EVERYTHING that affects the OS is up to date.  That includes all sorts of drivers, starting with video and audio.  And if you have an Intel chipset, use the Intel Driver Utility to update those drivers.  It’s very quick and easy.  For the video and audio drivers, some can be updated by Intel, some by utilities on the vendor web sites, and some you just have to figure out yourself.  But don’t be lazy here; old drivers and Windows Service Packs are a poor mix. If you have 3rd party software, check to see if they have any updates for you.  They might not say that they are for the Service Pack but you cut your risk of things not working if you do this. Shut off the Antivirus software (especially if 3rd party). Reboot, hitting F8 to get the SafeMode menu.  Choose SafeMode with Networking. Log into the Administrator account to ensure that you have the right to install the SP. Run the SP.  It won’t be very fancy this way.  Maybe 45 minutes later it will reboot and then finish configuring itself, finally letting you log in. Total installation time on most of my PC’s was about 1 hour but that followed hours of preparation on each. On a separate note, I recently got on the Nvidia web site and their utility told me I had a new driver available for my GeForce 8600M GS.  This laptop had come with Vista, now has Win 7 SP1.  I had a big surprise from this driver update; the Windows Experience Score on the graphics side went way up.  Kudo’s to Nvidia for doing a driver update that actually helps day to day usage.  And unlike ATI’s updates (which I need for my AGP based system), this update was fairly quick and very easy.  Also, Nvidia drivers have never, as I can recall, given me BSOD’s, many of which I’ve gotten from ATI (TDR errors).How to Enable Google Chrome’s Secret Gold IconHTG Explains: What’s the Difference Between the Windows 7 HomeGroups and XP-style Networking?Internet Explorer 9 Released: Here’s What You Need To Know

• Backing up my Windows Home Server to the Cloud&hellip;

  - by eddraper

  Ok, here’s my scenario: Windows Home Server with a little over 3TB of storage.  This includes many years of our home network’s PC backups, music, videos, etcetera. I’d like to get a backup off-site, and the existing APIs and apps such as CloudBerry Labs WHS Backup service are making it easy.  Now, all it’s down to is vendor and the cost of the actual storage.   So,  I thought I’d take a lazy Saturday morning and do some research on this and get the ball rolling.  What I discovered stunned me…   First off, the pricing for just about everything was loaded with complexity.  I learned that it wasn’t just about storage… it was about network usage, requests, sites, replication, and on and on. I really don’t see this as rocket science.  I have a disk image.  I want to put it in the cloud.  I’m not going to be be using it but once daily for incremental backups.  Sounds like a common scenario.  Yes, if “things get real” and my server goes down, I will need to bring down a lot of data and utilize a fair amount of vendor infrastructure.  However, this may never happen.  Offsite storage is an insurance policy.   The complexity of the cost structures, perhaps by design, create an environment where it’s incredibly hard to model bottom line costs and compare vendor all-up pricing.  As it is a “lazy Saturday morning,” I’m not in the mood for such antics and I decide to shirk the endeavor entirely.  Thus, I decided to simply fire up calc.exe and do some a simple arithmetic model based on price per GB.  I shuddered at the results.  Certainly something was wrong… did I misplace a decimal point?  Then I discovered CloudBerry’s own calculator.   Nope, I hadn’t misplaced those decimals after all.  Check it out (pricing based on 3174 GB):   Amazon S3 $398.00 per month $4761 per year Azure $396.75 per month $4761 per year Google $380.88 per month $4570.56 per year   Conclusion: Rampant crack smoking at vendors.  Seriously.  Out. Of. Their. Minds. Now, to Amazon’s credit, vision, and outright common sense, they had one offering which directly addresses my scenario:   Amazon Glacier $31.74 per month $380.88 per year   hmmm… It’s on the table.  Let’s see what it would cost to just buy some drives, an enclosure and cart them over to a friend’s house.   2 x 2TB Drives from NewEgg.com $199.99   Enclosure $39.99     $239.98   Carting data to back and forth to friend’s within walking distance pain   Leave drive unplugged at friend’s $0 for electricity   Possible data loss No way I can come and go every day.     I think I’ll think on this a bit more…

• Launch Webcast Q&A: Oracle WebCenter Suite 11g - The Platform for the Modern User Experience

  - by howard.beader(at)oracle.com

  Did you have a chance to watch the Oracle WebCenter Suite 11g Launch Webcast yet? Andy MacMillan presented some great information on the webcast and answered quite a few of your questions in the Q&A session as well. For your reading pleasure we have captured a number of the questions and answers and they are summarized below: Question: Can you tell me what should our Portal strategy be for integrating and extending our Oracle enterprise applications? Answer: We recommend that you look at this in two steps, the first would be to ensure that you have a good understanding of our common user experience architecture. Internally our product teams at Oracle are already investing in this quite heavily today for Fusion Applications and this is driving natural convergence from a UX strategy standpoint. The second step would be to look at how best to componentize the back office applications so that the business users across your organization can take advantage of these -- don't make it just about putting a new skin on top of what you already have from an application standpoint, instead look at how best to embed the social computing capabilities as part of the solution for your business users. Question: We are currently using the BEA WebLogic Portal now, should we stay on WLP or should we be looking at moving to WebCenter or when should we move to WebCenter? Answer: Our strategy has been called "Continue & Converge", this theme means that you can continue to use WebLogic or Plumtree portals until your organization is ready to move to WebCenter and in the mean time you can continue to deploy what you need to in your organization of WLP or WCI Portals with the full support of Oracle. In addition WebCenter Services can be leveraged for social computing to complement what you are already doing today and enable your organization to take advantage of some of the latest and greatest social computing capabilities. We have migration scripts and conversion capabilities available as well as programs where Oracle can help you evaluate your options to decide how best to move forward. WebCenter provides the best of the best capabilities and will enable you to take advantage of new capabilities that may not exist in your current portal today. In the end though it's up to you as a customer as to when you want to make the transition to Oracle WebCenter Suite. Question: Can you tell me how is Oracle leveraging WebCenter internally and for its Application and Middleware product UX strategies? Answer: Internally, Oracle is leveraging WebCenter for our employees and thus far we are seeing significant updates with our users taking advantage of the business activity streams, team spaces and collaboration capabilities. From a product strategy standpoint, our product teams are taking advantage of the common user experience architecture and leveraging WebCenter to provide social and collaborative capabilities to the Oracle Applications and providing new types of composite applications with what is coming with Fusion Applications. WebCenter also provides a common user experience across all the products in the Oracle Fusion Middleware family as well. Question: Our organization is currently using SharePoint, but we are also an Oracle Applications customer, how should we be thinking about WebCenter as we move forward? Answer: Great question. Typically, we are seeing organizations using SharePoint for its core use cases of small team collaboration and file server replacement. WebCenter can connect to SharePoint as a content source to feed into WebCenter quite easily and it leverages the robust Oracle ECM product under WebCenter as well. In addition, SharePoint team sites can be connected to WebCenter utilizing our SharePoint connector. With Oracle WebCenter though, we are really targeting business users and enterprise applications, thus affecting positive change on the processes that drive the business to improve productivity across your organization. Question: Are organizations today using WebCenter as a Web platform for externally facing public websites? Answer: Yes, we are seeing a convergence around web content management and portal types of websites with customers converting them from just broadcasting content to making it a much richer personalized experience and also exposing back-office applications as well. Web Content Management capabilities are already embedded in WebCenter so that organizations can take advantage now of the benefits a personalized web experience provides for your customers. This is simply a short summary of a few of the questions addressed on the webcast, please tune in now to learn more about Oracle WebCenter, the user experience platform for the enterprise and the web!

• Wipe, Delete, and Securely Destroy Your Hard Drive’s Data the Easy Way

  - by The Geek

  Giving a computer to somebody else? Maybe you’re putting it out on Craigslist to sell to a stranger—either way, you’ll want to make sure that your drive is completely wiped, scrubbed, and clean of any personal data. Here’s the easy way to do it. If you only have access to an Ubuntu Live CD or thumb drive, you can actually use that instead if you prefer, and we’ve got you covered with a full guide to securely wiping your PC’s hard drive. Otherwise, keep reading. Wipe the Drive with DBAN Darik’s Boot and Nuke CD is the easiest way to permanently and totally destroy every bit of personal information on that drive—nobody is going to recover a thing once this is done. The first thing you’ll need to do is download a copy of the ISO image, and then burn it to a blank CD with something really useful like Imgburn. Just choose Burn image to Disc at the start screen, select the little file icon, grab the downloaded ISO, and then go. If you need a little more help, we’ve got you covered with a beginner’s guide to burning an ISO image. Once you’re done, stick the disc into the drive, start the PC up, and then once you boot to the DBAN prompt you’ll see a menu. You can pretty much ignore everything on here, and just type… autonuke And there you are, your disk is now being securely wiped. Once it’s all done, you can remove the CD, and then either pack the PC up to sell, or re-install Windows on there if you feel like it. More Advanced Method If you’re really paranoid, want to run a different type of wipe, or just like fiddling with the options, you can choose F3 or hit Enter at the prompt to head to the advanced selection screen. Here you can choose exactly which drive to wipe, or hit the M key to change the method. You’ll be able to choose between a bunch of different wipe options. The Quick Erase is all you really need though.   So there you are, easy PC wiping in one package. What about you? Do you make sure to wipe your old PCs before giving them away? Personally I’ve always just yanked out the hard drives before I got rid of an old PC, but that’s just me.

• Create a Search Filter List in Google Chrome

  - by Asian Angel

  Are you tired of unwanted and/or non-relevant results cluttering up the search results at Bing, Yahoo, and Google? With the Search Filter extension for Chrome you can easily remove the unwanted “chaff” from your search results. Note: The extension only works on Bing, Yahoo, and Google at this time. Before For our example we conducted a search for “anime wallpapers” at Yahoo Singapore, Bing Singapore, and Google. In each set of results we decided to focus on results that would display either a yellow or red warning color from WOT. You can see our targeted result for Yahoo Singapore… The one for Bing Singapore… And the targeted result from Google. Search Filter in Action As soon as you install the extension you should take a quick look at the “Options”. At first the “Filters List Area” will be empty but will not remain so for long as you create your own filter list. The second part may or may not be of interest to you…the ability to opt into the filter service. If you opt in your filter list will be connected to your “Google Account” and will be available on any of your Chrome installs with the extension installed (and set to “Opt In”). Keep in mind that if you choose this option the filter list that you create will be aggregated anonymously and have a GUID number attached to it. After installing the extension we refreshed each of our three search pages…notice the small red circle button beside each search result link. Clicking on the red circle button will cause the entire browser window area to “shade out” temporarily while you decide between adding that website to the filter list or cancelling the action. If you add a website to the filter list that result will immediately disappear from the search results list without refreshing the webpage. Looks like we have another website at the bottom that we could add to the filter list… Click, click, click! After adding one website from each of the three search services you can see that our filter list has gotten off to a nice start. If for some reason you accidentally add a website to the list or change your mind about a website simply click on the red circle button to remove that particular listing. Conclusion If you are looking for an easy way to create a search filter list then this is definitely an extension that is worth taking the time to look at.

I'd like to introduce a new member of the Oracle WebCenter Team, Christian Finn. We decided to let him do his own intros today. Look for his guest posts next week and he'll be a frequent contributor to WebCenter blog and voice of the community. Hello (Oracle) World! Hi everyone, my name is Christian Finn. It’s a coder’s tradition to have “hello world” be the first output from a new program or in a new language. While I have left my coding days far behind, it still seems fitting to start my new role here at Oracle by saying hello to all of you—our customers, partners and my colleagues. So by way of introduction, a little background about me. I am the new senior director for evangelism on the WebCenter product management team. Not only am I new to Oracle, but the evangelism team is also brand new. Our mission is to raise the profile of Oracle in all of the markets/conversations in which WebCenter competes—social business, collaboration, portals, Internet sites, and customer/audience engagement. This is all pretty familiar turf for me because, as some of you may know, until recently I was the director of product management at Microsoft for Microsoft SharePoint Server and several other SharePoint products. And prior to that, I held management roles at Microsoft in marketing, channels, learning, and enterprise sales. Before Microsoft, I got my start in the industry as a software trainer and Lotus Notes consultant. I am incredibly excited to be joining Oracle at this time because of the tremendous opportunity that lies ahead to improve how people and businesses work. Of all the vendors offering a vision for social business, Oracle is unique in having best of breed strength in market (or coming soon) in all three critical areas: customer experience management; the middleware and back-end applications that run your business; and in the social, collaboration, and content technologies that are the connective tissue between them. Everyone else can offer one or two of the above, but not all three unified together. So it is a great time to come board and there’s a fantastic team of people hard at work on building great products for you. In the coming weeks and months you’ll be hearing much more from us. For now, we’ll kick things off with some blog posts here on the WebCenter blog. Enjoy the reads and please share your thoughts with me over Twitter on @cfinn.

• Test and Report Add-on Compatibility in Firefox

  - by Asian Angel

  Now that the new version of Firefox is out you probably have a favorite extension or two that has not updated yet. You can get that extension working again, test it, and report back to Mozilla on how well it does with the Add-on Compatibility Reporter extension. Before For our example we chose a great extension that unfortunately has not been updated yet. As you can see here Firefox is refusing to let the extension install. After As soon as you install Add-on Compatibility Reporter you will be presented with an information page on how the extension works and what you can do with it. You should definitely take a moment to read this as it is very helpful. After trying our non-compatible extension again we were able to proceed with the install process. Notice at the bottom that “compatibility checking” has been overridden. Success! As soon as we restarted our browser it was easy to see the “non-compatible icon” in the “Add-ons Manager Window”…but the extension did install though (terrific!). Clicking on the extension’s entry will reveal a new button in the lower right corner. Using the “Compatibility Drop-Down Menu” you can report if the extension is working as well as before or if it is actually having problems. The extension that we used for our example had no problems whatsoever so good news there. Whichever option you choose you will be presented with a small “Report Window” with information about the extension, your browser’s version number, and your operating system. Click “Submit Report” to send it on its’ way. You will see a confirmation message letting you know that your report was successfully submitted. While the extension itself has not been altered in any form at least you have it working again and have helped verify whether it still works well or not. Notice the “notation” present now in place of the “Compatibility Button” that lets you know that you have already taken care of that particular extension. Looking great… Conclusion If you have a favorite extension that you miss using in the newest release of Firefox then this is definitely an extension to add to your browser. Not only will your extension start working again but you can let Mozilla know how well it is working and (hopefully) help get the extension updated.

• Dynamically creating meta tags in asp.net mvc

  - by Jalpesh P. Vadgama

  As we all know that Meta tag has very important roles in Search engine optimization and if we want to have out site listed with good ranking on search engines then we have to put meta tags. Before some time I have blogged about dynamically creating meta tags in asp.net 2.0/3.5 sites, in this blog post I am going to explain how we can create a meta tag dynamically very easily. To have meta tag dynamically we have to create a meta tag on server-side. So I have created a method like following. public string HomeMetaTags() { System.Text.StringBuilder strMetaTag = new System.Text.StringBuilder(); strMetaTag.AppendFormat(@"<meta content='{0}' name='Keywords'/>","Home Action Keyword"); strMetaTag.AppendFormat(@"<meta content='{0}' name='Descption'/>", "Home Description Keyword"); return strMetaTag.ToString(); } Here you can see that I have written a method which will return a string with meta tags. Here you can write any logic you can fetch it from the database or you can even fetch it from xml based on key passed. For the demo purpose I have written that hardcoded. So it will create a meta tag string and will return it. Now I am going to store that meta tag in ViewBag just like we have a title tag. In this post I am going to use standard template so we have our title tag there in viewbag message. Same way I am going save meta tag like following in ViewBag. public ActionResult Index() { ViewBag.Message = "Welcome to ASP.NET MVC!"; ViewBag.MetaTag = HomeMetaTags(); return View(); } Here in the above code you can see that I have stored MetaTag ViewBag. Now as I am using standard ASP.NET MVC3 template so we have our we have out head element in Shared folder _layout.cshtml file. So to render meta tag I have modified the Head tag part of _layout.cshtml like following. <head> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script> @Html.Raw(ViewBag.MetaTag) </head> Here in the above code you can see I have use @Html.Raw method to embed meta tag in _layout.cshtml page. This HTML.Raw method will embed output to head tag section without encoding html. As we have already taken care of html tag in string function we don’t need the html encoding. Now it’s time to run application in browser. Now once you run your application in browser and click on view source you will find meta tag for home page as following. That’s its It’s very easy to create dynamically meta tag. Hope you liked it.. Stay tuned for more.. Till then happy programming.

• Announcing the ASP.NET and Web Tools 2012.2 Release Candidate

  - by ScottGu

  This week the ASP.NET and Visual Web Developer teams delivered the Release Candidate of the ASP.NET and Web Tools 2012.2 update (formerly ASP.NET Fall 2012 Update BUILD Prerelease). This update extends the existing ASP.NET runtime and adds new web tooling to Visual Studio 2012. Whether you use Web Forms, MVC, Web API, or any other ASP.NET technology, there is something cool in this update for you. You can download and install the RC today: http://www.asp.net/vnext. Great ASP.NET Enhancements This update adds new ASP.NET templates and features, including: New ASP.NET MVC templates. Creating Facebook applications just became easier using the new Facebook Application template. In just a few easy steps you can create a Facebook application that gets data from the logged in user as well as integrates with their friends. A new Single Page Application template allows developers to build interactive client-side web apps using Knockout, jQuery, and ASP.NET Web API. Real-time communication support with ASP.NET SignalR.  This enables you to easily take advantage of the new WebSocket support in .NET 4.5, while also automatically degrading to long-polling and other protocols for older clients.  If you haven’t tried SignalR yet you should – it is awesome. New ASP.NET Web API functionality, including support for OData, integrated tracing, and automatically generating help page documentation for your API. New ASP.NET Friendly URL functionality. This new feature makes it very easy for Web Forms developers to generate cleaner looking URLs (without the .aspx extension). The Friendly URLs feature also makes it easier for developers to add mobile support to their applications with support for mobile .ASPX pages and  supporting switching between desktop and mobile views. It can be used with existing ASP.NET v4.0 applications. Visual Studio 2012 Web publishing enhancements. Web site projects now have the same publish experience as web application projects (including to Windows Azure Web Sites), and you can selectively publish files, see the differences between local and remote files, and update local to remote files or vice versa. Visual Studio 2012 Page Inspector enhancements. JavaScript selection mapping is now supported, and you can CSS updates in real-time. Visual Studio 2012 editor support for Knockout IntelliSense and pasting JSON as a .NET class (which makes it even easier to consume Web APIs from others). Visual Studio 2012 Project Template updates, including the latest versions of jQuery, jQuery UI, jQuery Validation, Modernirz, Knockout and more… How it is delivered You can download and install an integrated setup that contains the above enhancements today from http://www.asp.net/vnext. The new runtime functionality is delivered to ASP.NET via additional NuGet packages. This means that installing this update does not make any changes to the existing ASP.NET binaries, and thus does not cause any compatibility issues with existing projects. New projects will contain the new functionality and existing projects can be updated with the new NuGet packages. Summary Web development is changing, and ASP.NET is rapidly delivering new capabilities to developers that help them take full advantage of new capabilities.  The ASP.NET and Web Tools 2012.2 update installs in minutes without altering the current ASP.NET run time components. For a complete description see the Release Notes. Next week I plan to publish a tutorial showing how to build a cool Facebook application using the new Facebook template. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• How Exactly Is One Linux OS “Based On” Another Linux OS?

  - by Jason Fitzpatrick

  When reviewing different flavors of Linux, you’ll frequently come across phrases like “Ubuntu is based on Debian” but what exactly does that mean? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader PLPiper is trying to get a handle on how Linux variants work: I’ve been looking through quite a number of Linux distros recently to get an idea of what’s around, and one phrase that keeps coming up is that “[this OS] is based on [another OS]“. For example: Fedora is based on Red Hat Ubuntu is based on Debian Linux Mint is based on Ubuntu For someone coming from a Mac environment I understand how “OS X is based on Darwin”, however when I look at Linux Distros, I find myself asking “Aren’t they all based on Linux..?” In this context, what exactly does it mean for one Linux OS to be based on another Linux OS? So, what exactly does it mean when we talk about one version of Linux being based off another version? The Answer SuperUser contributor kostix offers a solid overview of the whole system: Linux is a kernel — a (complex) piece of software which works with the hardware and exports a certain Application Programming Interface (API), and binary conventions on how to precisely use it (Application Binary Interface, ABI) available to the “user-space” applications. Debian, RedHat and others are operating systems — complete software environments which consist of the kernel and a set of user-space programs which make the computer useful as they perform sensible tasks (sending/receiving mail, allowing you to browse the Internet, driving a robot etc). Now each such OS, while providing mostly the same software (there are not so many free mail server programs or Internet browsers or desktop environments, for example) differ in approaches to do this and also in their stated goals and release cycles. Quite typically these OSes are called “distributions”. This is, IMO, a somewhat wrong term stemming from the fact you’re technically able to build all the required software by hand and install it on a target machine, so these OSes distribute the packaged software so you either don’t need to build it (Debian, RedHat) or they facilitate such building (Gentoo). They also usually provide an installer which helps to install the OS onto a target machine. Making and supporting an OS is a very complicated task requiring a complex and intricate infrastructure (upload queues, build servers, a bug tracker, and archive servers, mailing list software etc etc etc) and staff. This obviously raises a high barrier for creating a new, from-scratch OS. For instance, Debian provides ca. 37k packages for some five hardware architectures — go figure how much work is put into supporting this stuff. Still, if someone thinks they need to create a new OS for whatever reason, it may be a good idea to use an existing foundation to build on. And this is exactly where OSes based on other OSes come into existence. For instance, Ubuntu builds upon Debian by just importing most packages from it and repackaging only a small subset of them, plus packaging their own, providing their own artwork, default settings, documentation etc. Note that there are variations to this “based on” thing. For instance, Debian fosters the creation of “pure blends” of itself: distributions which use Debian rather directly, and just add a bunch of packages and other stuff only useful for rather small groups of users such as those working in education or medicine or music industry etc. Another twist is that not all these OSes are based on Linux. For instance, Debian also provide FreeBSD and Hurd kernels. They have quite tiny user groups but anyway. Have something to add to the explanation? Sound off in the the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

• Willy Rotstein on Supply Chain Planning

  - by sarah.taylor(at)oracle.com

  Each time a merchandiser, buyer or planner in Retail makes a business decision around assortment, inventory, pricing and promotions there is an opportunity to improve both Profitability and Customer Service. Improving decision making, however, has always been a tricky business for retailers.  I have worked in this space for more than 15 years. I began my career as an academic, at Imperial College London, and then broadened this interest with Retailers, aiming to optimize their merchandising and supply chain decisions. Planning the business and optimizing profit is a complex process. The complexity arises from the variety of people involved, the large number of decisions to take across all business processes, the uncertainty intrinsic to the retail environment as well as the volume of data available for analysis.  Things are not getting any easier either. The advent of multi-channel, social media and mobile is taking these complexities to a new level and presenting additional opportunities for those willing to exploit them. I guess it is due to the complexities of the decision making process that, over the last couple of years working with Oracle Retail, I have witnessed a clear trend around the deployment of planning systems. Retailers are aiming to simplify their decision making processes. They want to use one joined up planning platform across the business and enhance it with "actionable" data mining and optimization techniques. At Oracle Retail, we have a vibrant community of international retailers who regularly come together to discuss the big issues in retail planning. It is a combination of fashion, grocery and speciality retailers, all sharing their best practice vision for planning and optimizing merchandise decisions. As part of the Retail Exchange program, at the recent National Retail Federation event in New York, I jointly hosted a Planning dinner with Peter Fitzgerald from Google UK, Retail Division. Those retailers from our international planning community who were in New York for the annual NRF event were able to attend. The group comprised some of Europe's great International Retail brands.  All sectors were represented by organisations like Mango, LVMH, Ahold, Morrisons, Shop Direct and River Island. They confirmed the current importance of engaging with Planning and Optimization issues. In particular the impact of the internet was a key topic. We had a great debate about new retail initiatives.  Peter highlighted how mobility is changing retail - in particular with the new "local availability search" initiative. We also had an exciting discussion around the opportunities to improve merchandising using the new data that is becoming available from search, social media and ecommerce sites. It will be our focus to continue to help retailers translate this data into better results while keeping their business operations simple. New developments in "actionable" analytics and computing capacity make this a very exciting area today. Watch this space for my contributions on these topics which will be made available through this blog. Oracle Retail has a strong Planning community. if you are a category manager, a planner, a buyer, a merchandiser, a retail supplier or any retail executive with a keen interest in planning then you would be very welcome to join Oracle Retail's Planning Community. As part of our community you will be able to join our in-person and virtual events, download topical white papers and best practice information specifically tailored to your area of interest.  If anyone would like to register their interest in joining our community of retailers discussing planning then please contact me at [email protected]   Willy Rotstein, Oracle Retail

• Employee Info Starter Kit: Project Mission

  - by Mohammad Ashraful Alam

  Employee Info Starter Kit is an open source ASP.NET project template that is intended to address different types of real world challenges faced by web application developers when performing common CRUD operations. Using a single database table ‘Employee’, it illustrates how to utilize Microsoft ASP.NET 4.0, Entity Framework 4.0 and Visual Studio 2010 effectively in that context. Employee Info Starter Kit is highly influenced by the concept ‘Pareto Principle’ or 80-20 rule. where it is targeted to enable a web developer to gain 80% productivity with 20% of effort with respect to learning curve and production. User Stories The user end functionalities of this starter kit are pretty simple and straight forward that are focused in to perform CRUD operation on employee records as described below. Creating a new employee record Read existing employee record Update an existing employee record Delete existing employee records Key Technology Areas ASP.NET 4.0 Entity Framework 4.0 T-4 Template Visual Studio 2010 Architectural Objective There is no universal architecture which can be considered as the best for all sorts of applications around the world. Based on requirements, constraints, environment, application architecture can differ from one to another. Trade-off factors are one of the important considerations while deciding a particular architectural solution. Employee Info Starter Kit is highly influenced by the concept ‘Pareto Principle’ or 80-20 rule, where it is targeted to enable a web developer to gain 80% productivity with 20% of effort with respect to learning curve and production. “Productivity” as the architectural objective typically also includes other trade-off factors as well as, such as testability, flexibility, performance etc. Fortunately Microsoft .NET Framework 4.0 and Visual Studio 2010 includes lots of great features that have been implemented cleverly in this project to reduce these trade-off factors in the minimum level. Why Employee Info Starter Kit is Not a Framework? Application frameworks are really great for productivity, some of which are really unavoidable in this modern age. However relying too many frameworks may overkill a project, as frameworks are typically designed to serve wide range of different usage and are less customizable or editable. On the other hand having implementation patterns can be useful for developers, as it enables them to adjust application on demand. Employee Info Starter Kit provides hundreds of “connected” snippets and implementation patterns to demonstrate problem solutions in actual production environment. It also includes Visual Studio T-4 templates that generate thousands lines of data access and business logic layer repetitive codes in literally few seconds on the fly, which are fully mock testable due to language support for partial methods and latest support for mock testing in Entity Framework. Why Employee Info Starter Kit is Different than Other Open-source Web Applications? Software development is one of the rapid growing industries around the globe, where the technology is being updated very frequently to adapt greater challenges over time. There are literally thousands of community web sites, blogs and forums that are dedicated to provide support to adapt new technologies. While some are really great to enable learning new technologies quickly, in most cases they are either too “simple and brief” to be used in real world scenarios or too “complex and detailed” which are typically focused to achieve a product goal (such as CMS, e-Commerce etc) from "end user" perspective and have a long duration learning curve with respect to the corresponding technology. Employee Info Starter Kit, as a web project, is basically "developer" oriented which actually considers a hybrid approach as “simple and detailed”, where a simple domain has been considered to intentionally illustrate most of the architectural and implementation challenges faced by web application developers so that anyone can dive into deep into the corresponding new technology or concept quickly. Roadmap Since its first release by 2008 in MSDN Code Gallery, Employee Info Starter Kit gained a huge popularity in ASP.NET community and had 1, 50,000+ downloads afterwards. Being encouraged with this great response, we have a strong commitment for the community to provide support for it with respect to latest technologies continuously. Currently hosted in Codeplex, this community driven project is planned to have a wide range of individual editions, each of which will be focused on a selected application architecture, framework or platform, such as ASP.NET Webform, ASP.NET Dynamic Data, ASP.NET MVC, jQuery Ajax (RIA), Silverlight (RIA), Azure Service Platform (Cloud), Visual Studio Automated Test etc. See here for full list of current and future editions.

• Fill a Flash Drive with Portable Software using Lupo PenSuite

  - by Asian Angel

  A flash drive full of portable software is helpful to have along wherever you go. The Lupo PenSuite lets you choose from three different versions to get the best fit for your everyday needs. Note: If running the full version you will need a 512 MB USB flash drive or larger. Using Lupo PenSuite The one window to watch for during the setup process is where you have the opportunity to add a specific language pack if needed. Outside of that all that you need to do is sit back and wait for the suite to be extracted. Note: Extraction times will vary based on version and extraction location. Here we browsed to our flash drive to extract it to… Once the setup process is complete locate and double click the Lupo_PenSuite.exe file. This one time window will present you the opportunity to start using the suite immediately, or go directly into the options. When the suite is active you will have a new system tray icon that operates as a start menu button. At the bottom you can monitor the remaining room on your flash drive, and use the close button to exit the suite (may display as a power button based on menu theme). A quick look at the set up inside the suite. There is a pre-configured area for organizing and storing your personal files. Prefer a classic style menu? Just select for it in the options (various tab) and enjoy a smaller streamlined look. Note: You can also change the theme for the regular menu and add a user pic. The suite provides access to your portable software and online sites. You get to enjoy the best of both as shown in the following examples. Websites will open using the suite’s portable Firefox install. VLC is ready to play your downloaded videos. The suite also has some very nice photo editing programs added in. Installing Additional Apps If one of your favorite programs is not included in the suite version, it only takes a few minutes to add it in. Go to the Additional Apps webpage, download the app(s), and extract them onto your hard-drive. Note: Link for additional apps webpage provided below. Add the extracted app(s) to the MyApps folder in the suite’s folder hierarchy. Click on ASuite in the suite’s start menu. Drag and drop the portable app’s exe file into the MyApps section in the ASuite window. Your new software’s shortcut should display as shown here. Close this window when finished. Checking the suite’s start menu will show your new software ready to be used. Conclusion If you need a good portable software collection to carry with you on a flash drive then Lupo PenSuite is definitely worth taking a look at. We tested Lupo PenSuite on XP, Vista, and Windows 7 and it works great on all three. Another popular choice is PortableApps and you can check out our Review of that too they are essentially the same thing, each is just packaged differently.

• Stay on Schedule in Chrome with DayHiker

  - by Matthew Guay

  Do you keep your schedule and tasks in Google Calendar?  Here’s a handy extension for Google Chrome that can keep you on top of your appointments without having to open Google Calendar in another tab. Integrate Google Calendar with Chrome DayHiker is a handy extension for Google Chrome that can help you stay on schedule in your browser.  Desktop applications typically can keep you notified easier with popups or alerts, but webapps require you to visit them to view your information.  DayHiker takes the best of both, and can make your Google Calendar work more like a desktop application. To get started, open the DayHiker page from the Chrome Extensions Gallery (link below), and click Install.  Confirm you wish to install it at the prompt. Now you’ll have a new extension button in your Chrome toolbar.  Click the calendar icon to view your Google Calendar.  You’ll need to be signed into your Google account for your calendar to display; click the key icon to select your account if it doesn’t show your appointments automatically. If you’re signed into multiple Google accounts, such as your public Gmail and a Google Apps account, you can select the calendar you wish and click Continue. Now you can quickly see your upcoming appointments.  Simply hover over the icon to see your upcoming events.  Or, just glance at it to see if there are any appointments coming up, as the indicator icon will change colors to show how long you have until your next appointment. Click the icon to see more information about your appointments. Or, click the Add link to add a new appointment.  If you need to edit the appointment details, click Edit Details and the appointment will open in Google Calendar for you to edit. You can also view and manage your tasks in Google Calendar.  Click the checkmark icon, and then add or check-off tasks directly from the extension pane. You can also set an alarm clock in DayHiker.  Click the green circle icon, and then enter the time for the alarm to go off.  Strangely it will only chime if the extension pane is left open, so if you click anywhere else in the browser or even switch to another program it will not chime.   If you’d like to customize DayHiker’s settings, right-click on it and select Options, or select Options in the Chrome Extensions page.  Here you can customize your badges and the DayHiker icon, or enter a custom domain for your Google Apps Pro calendar.   Conclusion If you rely on Google Calendar to stay on top of your schedule, DayHiker can help you stay scheduled and know what’s coming up.  We wish DayHiker supported multiple calendars so we could combine our Google Apps calendars with our personal Google Calendar, but even still, it is a very useful tool.  Whether you’re a tightly scheduled person or just like to jot down to-dos and keep track of them, this extension will help you do this efficiently with familiar Google tools.

• MySQL Cluster 7.3: On-Demand Webinar and Q&A Available

  - by Mat Keep

  The on-demand webinar for the MySQL Cluster 7.3 Development Release is now available. You can learn more about the design, implementation and getting started with all of the new MySQL Cluster 7.3 features from the comfort and convenience of your own device, including: - Foreign Key constraints in MySQL Cluster - Node.js NoSQL API  - Auto-installation of higher performance distributed, clusters We received some great questions over the course of the webinar, and I wanted to share those for the benefit of a broader audience. Q. What Foreign Key actions are supported: A. The core referential actions defined in the SQL:2003 standard are implemented: CASCADE RESTRICT NO ACTION SET NULL Q. Where are Foreign Keys implemented, ie data nodes or SQL nodes? A. They are implemented in the data nodes, therefore can be enforced for both the SQL and NoSQL APIs Q. Are they compatible with the InnoDB Foreign Key implementation? A. Yes, with the following exceptions: - InnoDB doesn’t support “No Action” constraints, MySQL Cluster does - You can choose to suspend FK constraint enforcement with InnoDB using the FOREIGN_KEY_CHECKS parameter; at the moment, MySQL Cluster ignores that parameter. - You cannot set up FKs between 2 tables where one is stored using MySQL Cluster and the other InnoDB. - You cannot change primary keys through the NDB API which means that the MySQL Server actually has to simulate such operations by deleting and re-adding the row. If the PK in the parent table has a FK constraint on it then this causes non-ideal behaviour. With Restrict or No Action constraints, the change will result in an error. With Cascaded constraints, you’d want the rows in the child table to be updated with the new FK value but, the implicit delete of the row from the parent table would remove the associated rows from the child table and the subsequent implicit insert into the parent wouldn’t reinstate the child rows. For this reason, an attempt to add an ON UPDATE CASCADE where the parent column is a primary key will be rejected. Q. Does adding or dropping Foreign Keys cause downtime due to a schema change? A. Nope, this is an online operation. MySQL Cluster supports a number of on-line schema changes, ie adding and dropping indexes, adding columns, etc. Q. Where can I see an example of node.js with MySQL Cluster? A. Check out the tutorial and download the code from GitHub Q. Can I use the auto-installer to support remote deployments? How about setting up MySQL Cluster 7.2? A. Yes to both! Q. Can I get a demo Check out the tutorial. You can download the code from http://labs.mysql.com/ Go to Select Build drop-down box Q. What is be minimum internet speen required for Geo distributed cluster with synchronous replication? A. if you're splitting you cluster between sites then we recommend a network latency of 20ms or less. Alternatively, use MySQL asynchronous replication where the latency of your WAN doesn't impact the latency of your reads/writes. Q. Where you can one learn more about the PayPal project with MySQL Cluster? A. Take a look at the following - you'll find press coverage, a video and slides from their keynote presentation  So, if you want to learn more, listen to the new MySQL Cluster 7.3 on-demand webinar  MySQL Cluster 7.3 is still in the development phase, so it would be great to get your feedback on these new features, and things you want to see!
