• At $20/month Windows Azure host my website with 99.97% uptime

  - by Gopinath

  Couple of years ago a reliable and decent performing Windows hosting was not affordable to many enthusiastic developers who want to try a startup idea or build a hobby site. I tried to start an ASP.NET website few years ago to provide services like – Mobile Tracing, Vehicle Tracing. But due to high cost of Windows hosting I developed those services using PHP (not an easy task for .NET developer) and hosted on them Linux servers.  But with recent evolution of Windows Azure, hosting ASP.NET websites on highly reliable servers is affordable. Today anyone can host a high responsive and available ASP.NET website for just $20/month using Windows Azure. My website coziie.com is running on Windows Azure and serves close to quarter millions visitors a month with 99.97% of uptime and most of the page load times are less than 3 seconds. All I spend to run this website is just around $20, if you translate it to India rupees its roughly Rs.1000. The web sever of coziie.com is powered by a single Extra Small Web role instance and the backend is powered by a SQL Azure instance. Azure is quite impressive to provide 99.97% of uptime. Response times during peak are around 3 seconds and on nomarl loads it is around 1.5 seconds. Here is the report of uptime provided by Royal Pingdom over last one year For just $20/month Windows Azure takes care of the following apart from hosting Patches up Windows OS to the latest version Upgrades ASP.NET to the latest version – coziie.com is running on ASP.NET MVC 3 and soon I’ll upgrade it to ASP.NET MVC 4 Hosts data on latest and best version Sql Server database SQL Azure maintains 3 copies of database and automatically recovers in case of server failures and disasters. I never worry about database backups/restore. Provides staging environment for deploying applications for testing purpose and move them to production – I upgrade  twice a month on average With Windows Azure I no longer focus on server maintenance or data backups. They are taken up by Microsoft team and I just focus on building my website. Wish there is a low cost Linux version of Windows Azure so that I can stop worrying about server maintenance of this blog!! If you are looking for a Windows hosting, look no further than Windows Azure. If you find $20/month is a bit expensive to start with you may explore Azure Website (sort of shared hosted environment) which is free to start with and as your traffic grows you can move to paid hosting.

• Building a Solaris 11 repository without network connection

  - by user12611852

  Solaris 11 has been released and is a fantastic new iteration of Oracle's rock solid, enterprise operating system.  One of the great new features is the repository based Image Packaging system.  IPS not only introduces new cloud based package installation services, it is also integrated with our zones, boot environment and ZFS file systems to provide a safe, easy and fast way to perform system updates. My customers typically don't have network access and, in fact, can't connect to any network until they have "Authority to connect."  It's useful, however, to build up a Solaris 11 system with additional software using the new Image Packaging System and locally stored repository. The Solaris 11 documentation describes how to create a locally stored repository with full explanations of what the commands do. I'm simply providing the quick and dirty steps.  The easiest way is to download the ISO image, burn to a DVD and insert into your DVD drive.  Then as root: pkg set-publisher -G '*' -g file:///cdrom/sol11repo_full/repo solaris Now you can to install software using the GUI package manager or the pkg commands.  If you would like something more permanent (or don't have a DVD drive), however, it takes a little more work. After installing Solaris 11, download (on another system perhaps) the two files that make up the Solaris 11 repository from our download site Sneaker-net the files to your Solaris 11 system Unzip and cat the two files together to create one large ISO image. The file is about 6.9 GB in size zfs create rpool/export/repoSolaris11 zfs set atime=off rpool/export/repoSolaris11 zfs set compression=on rpool/export/repoSolaris11 (save some space) lofiadm -a sol-11-1111-repo-full.iso /dev/lofi/1 mount -F hsfs /dev/lofi/1 /mnt You could stop here and set the publisher to point to the /mnt/repo location, however, this mount will not be persistent across reboots. Copy the repository from the mounted ISO image to a permanent, on disk location. rsync -aP /mnt/repo /export/repoSolaris11 pkgrepo -s /export/repoSolaris11 refresh pkg set-publisher -G '*' -g /export/repoSolaris11/repo solaris You now have a locally installed repository for adding additional software packages for Solaris 11.  The documentation also takes you through publishing your repository on the network so that others can access it.

• Sync Google Calendar with SharePoint Calendar

  - by dataintegration

  The ADO.NET Providers for Google and SharePoint make it easy to retrieve and update data in both Google's web services and SharePoint. This article shows how the SQL interface to data makes it easy to build applications that need to move data from one source to another. The application described here is a demo Windows application that synchronizes calendar events between Google and SharePoint, but the RSSBus Providers can be used to achieve integrations on both the .NET and the Java platforms, including more sophisticated features like full automation. Getting the Events Step 1: Google accounts can have several calendars. Obtain a list of a user's Google Calendars by issuing a query to the Calendars table. For example: SELECT * FROM Calendars. Step 2: In order to get a list of the events from a given Google Calendar, issue a query to the CalendarEvents table while specifying the CalendarId from the Calendars table. The resulting events can be further filtered by using the StartDateTime or EndDateTime columns. For example: SELECT * FROM CalendarEvents WHERE (CalendarId = '[email protected]') AND (StartDateTime >= '1/1/2012') AND (StartDateTime <= '2/1/2012') Step 3: SharePoint stores data in Lists. There are various types of lists, e.g., document lists and calendar lists. A SharePoint account can have several lists of the same type. To find all the calendar lists in SharePoint, use the ListLists stored procedure and inspect the BaseTemplate column. Step 4: The SharePoint data provider models each SharPoint list as a table. Get the events in a particular calendar by querying the table with the same name as the list. The events may be filtered further by specifying the EventDate or EndDate columns. For example: SELECT * FROM Calendar WHERE (EventDate >= '1/1/2012') AND (EventDate <= '2/1/2012') Synchronizing the Events Synchronizing the events is a simple process. Once the events from Google and SharePoint are available they can be compared and synchronized based on user preference. The sample application does this based on user input, but it is easy to create one that does the synchronization automatically. The INSERT, UPDATE, and DELETE statements available in both data providers makes it easy to create, update, or delete events as needed. Pre-Built Demo Application The executable for the demo application can be downloaded here. Note that this demo is built using BETA builds of the ADO.NET Provider for Google V2 and ADO.NET Provider for SharePoint V2, and will expire in 2013. Source Code You can download the full source of the demo application here. You will need the Google ADO.NET Data Provider V2 and the SharePoint ADO.NET Data Provider V2, which can be obtained here.

• Getting Started Plugging into the "Find in Projects" Dialog

  - by Geertjan

  In case you missed it amidst all the code in yesterday's blog entry, the "Find in Projects" dialog is now pluggable. I think that's really cool. The code yesterday gives you a complete example, but let's break it down a bit and deconstruct down to a very simple hello world scenario. We'll end up with as many extra tabs in the "Find in Projects" dialog as we need, for example, three in this case:  And clicking on any of those extra tabs will, in this simple example, simply show us this: Once we have that, we'll be able to continue adding small bits of code over the next few blog entries until we have something more useful. So, in this blog entry, you'll literally be able to display "Hello World" within a new tab in the "Find in Projects" dialog: import javax.swing.JComponent; import javax.swing.JLabel; import org.netbeans.spi.search.provider.SearchComposition; import org.netbeans.spi.search.provider.SearchProvider; import org.netbeans.spi.search.provider.SearchProvider.Presenter; import org.openide.NotificationLineSupport; import org.openide.util.lookup.ServiceProvider; @ServiceProvider(service = SearchProvider.class) public class ExampleSearchProvider1 extends SearchProvider { @Override public Presenter createPresenter(boolean replaceMode) { return new ExampleSearchPresenter(this); } @Override public boolean isReplaceSupported() { return false; } @Override public boolean isEnabled() { return true; } @Override public String getTitle() { return "Demo Extension 1"; } public class ExampleSearchPresenter extends SearchProvider.Presenter { private ExampleSearchPresenter(ExampleSearchProvider1 sp) { super(sp, true); } @Override public JComponent getForm() { return new JLabel("Hello World"); } @Override public SearchComposition composeSearch() { return null; } @Override public boolean isUsable(NotificationLineSupport nls) { return true; } } } That's it, not much code, works fine in NetBeans IDE 7.2 Beta, and is easier to digest than the big chunk from yesterday. If you make three classes like the above in a NetBeans module, and you install it, you'll have three new tabs in the "Find in Projects" dialog. The only required dependencies are Dialogs API, Lookup API, and Search in Projects API. Read the javadoc linked above and then in next blog entries we'll continue to build out something like the sample you saw in yesterday's blog entry.

• Gaming on Cloud

  - by technomad

  Sometimes I wonder the pundits of cloud computing are way to consumed with the enterprise applications. With all the CAPEX / OPEX, ROI-talk taking the center stage, an opportunity to affect masses directly is getting overlooked. I am a self proclaimed die hard gamer. I come from the generation of gamers who started their journey in DOS games like Wolfenstein 3D and Allan Border Cricket (the latter is still a favorite pastime). In the late 90s, a revolution called accelerated graphics started in DirectX and OpenGL. Games got more advanced. Likes of Quake III and Unreal Tournament became the crown jewels of the industry. But with all these advancements, there started a race. A race of GFX giants ATI and NVIDIA to beat each other for better frame and image quality. Revisions to the graphics chipsets became frequent. Games became eye candies but at the cost of more GPU power / memory. Every eagerly awaited title started demanding more muscle power in graphics and PC hardware. Latest games and all the liquid smooth frame rates became the territory of the once with deep pockets who could spend lavishly on latest hardware. Enthusiasts like yours truly, who couldn’t afford this route, started exploring over-clocking, optimized hardware cooling... etc. to pursue the passion. Ever rising cost of hardware requirements lead to rampant piracy of PC games. Gamers were willing to spend on the latest titles, but the ones with tight budget prefer hardware upgrades against a legal copy of the game. It was also fueled by emergence of the P2P file sharing networks. Then came the era of Xbox and PS3s. It solved the major issue of hardware standardization and provided an alternative to ever increasing hardware costs. I have always admired these consoles, but being born and brought up in a keyboard/mouse environment, I still find it difficult to play first person shooters with a gamepad. I leave the topic of PC v/s Consol gaming for another day, but the bottom line is… PC gamers deserve an equally democratized solution. This is where I think Cloud Computing can come to rescue. It can minimize hardware requirements. Virtually end the software piracy and rationalize costs for gamers. Subscription based models like pay-as-you-play. In game rewards, like extended subscription credits for exceptional gamers (oh yes, I have beaten Xaero on nightmare in Quake III, time and again!) Easy deployment for patches and fixes. Better game AI. The list goes on and on… Fortunately, companies like OnLive are thinking in the same direction. Their gaming service is all set to launch on 17th June 2010 in E3 2010 expo in L.A. I wish them all the luck. I hope they will start a trend which will bring the smiles back on the face of budget gamers with the help of cloud computing.

• SEO effects of intermix of WP blog, custom PHP site and FB app game

  - by melbournetechlover

  We're a melbourne tech company in the process of building a custom site in PHP. We plan to launch a "pre-launch" page which is also custom coded (CSS3 on twitter bootstrap framework + HTML5 front end and PHP back end). On that site will be a link to a blog - the idea behind this is to build up ranking for a variety of relevant keywords prior to the full site going live (given the majority of the site is a member only community anyway so the blog is really the main way we'll be able to execute on-site SEO. Ideally, we would like to install wordpress in a subdirectory on our servers and just customise the header to look the same as the landing page of the website. But some questions and concerns... Is there any detrimental effect on SEO efforts in having two separate systems (one custom PHP, the other an installation of wordpress) to manage the blog vs the rest of the site? Are there any benefits or detriments to installing on a sub domain such as blog.sitename.com vs. sitename.com/blog. My preference would be sitename.com/blog as it feels neater - but open to suggestions based on knowledge of Google preferences. Separately, we are building a Facebook app which is under another site name. Again because we are launching this app first, from an SEO perspective, would it actually be better to run it from a sub domain on the main site - e.g. gamename.mainsitename.com instead of on app.gamename.com? Currently we have it on app.gamename.com, but if there are SEO benefits to moving it to the other domain and server then we'll do it. Basically we don't want to have our SEO efforts divided - will Google algorithms prefer two sites heavily referring traffic, or is it better to focus our efforts on one. I guess that's the crux of the issue. But the other one is - does Google care about traffic accessing a page built for the Facebook app iFrame - does that count toward rankings? Sorry I hope these questions aren't too complex - but we're in the tech world every day and still can't seem to find a good answer to these ones...hence I'm taking to the forums!! Free beer for whoever can give me a solid answer!

• Getting Help with 'SEPA' Questions

  - by MargaretW

  What is 'SEPA'? The Single Euro Payments Area (SEPA) is a self-regulatory initiative for the European banking industry championed by the European Commission (EC) and the European Central Bank (ECB). The aim of the SEPA initiative is to improve the efficiency of cross border payments and the economies of scale by developing common standards, procedures, and infrastructure. The SEPA territory currently consists of 33 European countries -- the 28 EU states, together with Iceland, Liechtenstein, Monaco, Norway and Switzerland. Part of that infrastructure includes two new SEPA instruments that were introduced in 2008: SEPA Credit Transfer (a Payables transaction in Oracle EBS) SEPA Core Direct Debit (a Receivables transaction in Oracle EBS) A SEPA Credit Transfer (SCT) is an outgoing payment instrument for the execution of credit transfers in Euro between customer payment accounts located in SEPA. SEPA Credit Transfers are executed on behalf of an Originator holding a payment account with an Originator Bank in favor of a Beneficiary holding a payment account at a Beneficiary Bank. In R12 of Oracle applications, the current SEPA credit transfer implementation is based on Version 5 of the "SEPA Credit Transfer Scheme Customer-To-Bank Implementation Guidelines" and the "SEPA Credit Transfer Scheme Rulebook" issued by European Payments Council (EPC). These guidelines define the rules to be applied to the UNIFI (ISO20022) XML message standards for the implementation of the SEPA Credit Transfers in the customer-to-bank space. This format is compliant with SEPA Credit Transfer version 6. A SEPA Core Direct Debit (SDD) is an incoming payment instrument used for making domestic and cross-border payments within the 33 countries of SEPA, wherein the debtor (payer) authorizes the creditor (payee) to collect the payment from his bank account. The payment can be a fixed amount like a mortgage payment, or variable amounts such as those of invoices. The "SEPA Core Direct Debit" scheme replaces various country-specific direct debit schemes currently prevailing within the SEPA zone. SDD is based on the ISO20022 XML messaging standards, version 5.0 of the "SEPA Core Direct Debit Scheme Rulebook", and "SEPA Direct Debit Core Scheme Customer-to-Bank Implementation Guidelines". This format is also compliant with SEPA Core Direct Debit version 6. EU Regulation #260/2012 established the technical and business requirements for both instruments in euro. The regulation is referred to as the "SEPA end-date regulation", and also defines the deadlines for the migration to the new SEPA instruments: Euro Member States: February 1, 2014 Non-Euro Member States: October 31, 2016. Oracle and SEPA Within the Oracle E-Business Suite of applications, Oracle Payables (AP), Oracle Receivables (AR), and Oracle Payments (IBY) provide SEPA transaction capabilities for the following releases, as noted: Release 11.5.10.x -  AP & AR Release 12.0.x - AP & AR & IBY Release 12.1.x - AP & AR & IBY Release 12.2.x - AP & AR & IBY Resources To assist our customers in migrating, using, and troubleshooting SEPA functionality, a number of resource documents related to SEPA are available on My Oracle Support (MOS), including: R11i: AP: White Paper - SEPA Credit Transfer V5 support in Oracle Payables, Doc ID 1404743.1R11i: AR: White Paper - SEPA Core Direct Debit v5.0 support in Oracle Receivables, Doc ID 1410159.1R12: IBY: White Paper - SEPA Credit Transfer v5 support in Oracle Payments, Doc ID 1404007.1R12: IBY: White Paper - SEPA Core Direct Debit v5 support in Oracle Payments, Doc ID 1420049.1R11i/R12: AP/AR/IBY: Get Help Setting Up, Using, and Troubleshooting SEPA Payments in Oracle, Doc ID 1594441.2R11i/R12: Single European Payments Area (SEPA) - UPDATES, Doc ID 1541718.1R11i/R12: FAQs for Single European Payments Area (SEPA), Doc ID 791226.1

• Caching factory design

  - by max

  I have a factory class XFactory that creates objects of class X. Instances of X are very large, so the main purpose of the factory is to cache them, as transparently to the client code as possible. Objects of class X are immutable, so the following code seems reasonable: # module xfactory.py import x class XFactory: _registry = {} def get_x(self, arg1, arg2, use_cache = True): if use_cache: hash_id = hash((arg1, arg2)) if hash_id in _registry: return _registry[hash_id] obj = x.X(arg1, arg2) _registry[hash_id] = obj return obj # module x.py class X: # ... Is it a good pattern? (I know it's not the actual Factory Pattern.) Is there anything I should change? Now, I find that sometimes I want to cache X objects to disk. I'll use pickle for that purpose, and store as values in the _registry the filenames of the pickled objects instead of references to the objects. Of course, _registry itself would have to be stored persistently (perhaps in a pickle file of its own, in a text file, in a database, or simply by giving pickle files the filenames that contain hash_id). Except now the validity of the cached object depends not only on the parameters passed to get_x(), but also on the version of the code that created these objects. Strictly speaking, even a memory-cached object could become invalid if someone modifies x.py or any of its dependencies, and reloads it while the program is running. So far I ignored this danger since it seems unlikely for my application. But I certainly cannot ignore it when my objects are cached to persistent storage. What can I do? I suppose I could make the hash_id more robust by calculating hash of a tuple that contains arguments arg1 and arg2, as well as the filename and last modified date for x.py and every module and data file that it (recursively) depends on. To help delete cache files that won't ever be useful again, I'd add to the _registry the unhashed representation of the modified dates for each record. But even this solution isn't 100% safe since theoretically someone might load a module dynamically, and I wouldn't know about it from statically analyzing the source code. If I go all out and assume every file in the project is a dependency, the mechanism will still break if some module grabs data from an external website, etc.). In addition, the frequency of changes in x.py and its dependencies is quite high, leading to heavy cache invalidation. Thus, I figured I might as well give up some safety, and only invalidate the cache only when there is an obvious mismatch. This means that class X would have a class-level cache validation identifier that should be changed whenever the developer believes a change happened that should invalidate the cache. (With multiple developers, a separate invalidation identifier is required for each.) This identifier is hashed along with arg1 and arg2 and becomes part of the hash keys stored in _registry. Since developers may forget to update the validation identifier or not realize that they invalidated existing cache, it would seem better to add another validation mechanism: class X can have a method that returns all the known "traits" of X. For instance, if X is a table, I might add the names of all the columns. The hash calculation will include the traits as well. I can write this code, but I am afraid that I'm missing something important; and I'm also wondering if perhaps there's a framework or package that can do all of this stuff already. Ideally, I'd like to combine in-memory and disk-based caching.

• How can I achieve a 3D-like effect with spritebatch's rotation and scale parameters

  - by Alic44

  I'm working on a 2d game with a top-down perspective similar to Secret of Mana and the 2D Final Fantasy games, with one big difference being that it's an action rpg using a 3-dimensional physics engine. I'm trying to draw an aimer graphic (basically an arrow) at my characters' feet when they're aiming a ranged weapon. At first I just converted the character's aim vector to radians and passed that into spritebatch, but there was a problem. The position of every object in my world is scaled for perspective when it's drawn to the screen. So if the physics engine coordinates are (1, 0, 1), the screen coords are actually (1, .707) -- the Y and Z axis are scaled by a perspective factor of .707 and then added together to get the screen coordinates. This meant that the direction the aimer graphic pointed (thanks to its rotation value passed into spritebatch) didn't match up with the direction the projectile actually traveled over time. Things looked fine when the characters fired left, right, up, or down, but if you fired on a diagonal the perspective of the physics engine didn't match with the simplistic way I was converting the character's aim direction to a screen rotation. Ok, fast forward to now: I've got the aimer's rotation matched up with the path the projectile will actually take, which I'm doing by decomposing a transform matrix which I build from two rotation matrices (one to represent the aimer's rotation, and one to represent the camera's 45 degree rotation on the x axis). My question is, is there a way to get not just rotation from a series of matrix transformations, but to also get a Vector2 scale which would give the aimer the appearance of being a 3d object, being warped by perspective? Orthographic perspective is what I'm going for, I think. So, the aimer arrow would get longer when facing sideways, and shorter when facing north and south because of the perspective. At the same time, it would get wider when facing north and south, and less wide when facing right or left. I'd like to avoid actually drawing the aimer texture in 3d because I'm still using spritebatch's layerdepth parameter at this point in my project, and I don't want to have to figure out how to draw a 3d object within the depth sorting system I already have. I can provide code and more details if this is too vague as a question... This is my first post on stack exchange. Thanks a lot for reading! Note: (I think) I realize it can't be a technically correct 3D perspective, because the spritebatch's vector2 scaling argument doesn't allow for an object to be skewed the way it actually should be. What I'm really interested in is, is there a good way to fake the effect, or should I just drop it and not scale at all? Edit to clarify without the help of a picture (apparently I can't post them yet): I want the aimer arrow to look like it has been painted on the ground at the character's feet, so it should appear to be drawn on the ground plane (in my case the XZ plane) which should be tilted at a 45 degree angle (around the X axis) from the viewing perspective.

• Social HCM: Is Your Team Listening?

  - by Mike Stiles

  Does integrating Social HCM into your enterprise make sense? Consider Sam and Christina. Sam is a new hire at a big company. On the job 3 weeks, a question has come up on how to properly file an expense report to get reimbursed. It was covered in the onboarding session, but shockingly enough, Sam didn’t memorize or write down every word of the session. The answer is probably in a handout, in a stack of handouts 2 inches thick. It also might be on the employee web site…somewhere. Christina is a new hire at a different big company. She has the same question. She logs into her company’s social network, goes to the “new hires” group, asks her question and gets an answer in seconds. Christina says, “Cool!” Sam says, “Grrrr.” It’s safe to say the qualified talent your company wants is accustomed to using social platforms to communicate and get quick answers. As such, Christina is comfortable at her new company, whereas Sam is wondering what he’s gotten himself into. Companies that cling to talent communication and management systems that don’t speak to talent’s needs or expectations put themselves at risk. Right from the recruiting stage, prospects can determine if a company has embraced the communications tools of the 21st century. If they don’t see it, alarm bells go off. With great talent more in demand than ever, enterprises should reconsider making “this is the way we do it, you adapt to us” their mantra. Other blogs have clearly outlined that apart from meeting top recruits’ expectations, Social HCM benefits the organization itself in terms of efficiency, talent performance & measurement. Recruiting: Jobvite shows 64% of companies hired using social. 89% of job seekers are using social in their search. Social can give employers access to relevant communities of prospects and advance the brand. Nucleus Research found general hiring software can provide over 1,000% ROI by reducing churn and improving screening. Social talent acquisition should perform at least as well. Learning & Development:Employees, learning from the company or from peers, can be kept on top of the latest needed skillsets and engage in self-paced training so as to advance within the company. Performance Management:Just as gamers are egged on by levels and achievements, talent can reach for workplace kudos, be they shout-outs from peers & managers or formally established milestones. Plus employee reviews become consistent and fair as managers have access to the cumulative feedback social offers. Workflow and Collaboration:With workforces dispersing in terms of physical location, social provides a platform that helps eliminate drawbacks that would have brought just 10 years ago. Finding and connecting with just the right colleague to get the most relevant info at any given time has never been more possible…or expected. While yes, marketing has taken the social lead inside the enterprise, HCM (with the word “human” right there in its name) is the obvious locale for the next big integration of social in business. The technology is there. At Oracle, Fusion HCM apps are deeply embedded with Social HCM…just one example of systems taking social across the enterprise. Christina’s company is communicating with her in ways she’s used to. Sam’s company may as well be trying to talk to him using signal flags. @mikestilesPhoto via stock.xchng

• Per-pixel collision detection - why does XNA transform matrix return NaN when adding scaling?

  - by JasperS

  I looked at the TransformCollision sample on MSDN and added the Matrix.CreateTranslation part to a property in my collision detection code but I wanted to add scaling. The code works fine when I leave scaling commented out but when I add it and then do a Matrix.Invert() on the created translation matrix the result is NaN ({NaN,NaN,NaN},{NaN,NaN,NaN},...) Can anyone tell me why this is happening please? Here's the code from the sample: // Build the block's transform Matrix blockTransform = Matrix.CreateTranslation(new Vector3(-blockOrigin, 0.0f)) * // Matrix.CreateScale(block.Scale) * would go here Matrix.CreateRotationZ(blocks[i].Rotation) * Matrix.CreateTranslation(new Vector3(blocks[i].Position, 0.0f)); public static bool IntersectPixels( Matrix transformA, int widthA, int heightA, Color[] dataA, Matrix transformB, int widthB, int heightB, Color[] dataB) { // Calculate a matrix which transforms from A's local space into // world space and then into B's local space Matrix transformAToB = transformA * Matrix.Invert(transformB); // When a point moves in A's local space, it moves in B's local space with a // fixed direction and distance proportional to the movement in A. // This algorithm steps through A one pixel at a time along A's X and Y axes // Calculate the analogous steps in B: Vector2 stepX = Vector2.TransformNormal(Vector2.UnitX, transformAToB); Vector2 stepY = Vector2.TransformNormal(Vector2.UnitY, transformAToB); // Calculate the top left corner of A in B's local space // This variable will be reused to keep track of the start of each row Vector2 yPosInB = Vector2.Transform(Vector2.Zero, transformAToB); // For each row of pixels in A for (int yA = 0; yA < heightA; yA++) { // Start at the beginning of the row Vector2 posInB = yPosInB; // For each pixel in this row for (int xA = 0; xA < widthA; xA++) { // Round to the nearest pixel int xB = (int)Math.Round(posInB.X); int yB = (int)Math.Round(posInB.Y); // If the pixel lies within the bounds of B if (0 <= xB && xB < widthB && 0 <= yB && yB < heightB) { // Get the colors of the overlapping pixels Color colorA = dataA[xA + yA * widthA]; Color colorB = dataB[xB + yB * widthB]; // If both pixels are not completely transparent, if (colorA.A != 0 && colorB.A != 0) { // then an intersection has been found return true; } } // Move to the next pixel in the row posInB += stepX; } // Move to the next row yPosInB += stepY; } // No intersection found return false; }

• MPI Cluster Debugger launch integration in VS2010

  Let's assume that you have all the HPC bits installed and that you have existing MPI code (or you created a "Hello World" project using the MPI project template). Of course, you create a single MPI application and at runtime it will correspond to multiple processes (of the same app) launched on multiple nodes (i.e. machines) on the cluster. So how do you debug such a situation by simply hitting the familiar "F5" keystroke (i.e. Debug - Start Debugging)?WATCH IT INSTEAD OF READING ABOUT ITIf you can't bear to read through all the details below, just watch this 19-minute screencast explaining this VS2010 feature. Alternatively, or even additionally, keep on reading.REQUIREMENTWhen you debug an MPI application, you would want the copying of resources from your client machine (where Visual Studio is installed) to each compute node (where Windows HPC Server is installed) to take place automatically for you. 'Resources' in the previous sentence includes your application binary, plus any binary or data dependencies it may have, plus PDBs if needed, plus the debug CRT of the correct bitness, plus msvsmon for remote debugging to work. You would also want, after copying is complete, to have your app and msvsmon launched and attached so that you can hit breakpoints back in Visual Studio on your client machine. All these thing that you would want are delivered in VS2010.STEPS TO F51. In your MPI project where you have placed a breakpoint go to Project Properties - Configuration Properties - Debugging. Ensure the "Debugger to launch" combo box value is set to MPI Cluster Debugger.2. There are a whole bunch of properties here and typically you can ignore all of them except one: Run Environment. By default it is set to run 1 process on your local machine and if you change the number after that to, for example, 4 it will launch 4 processes of your app on your local machine.You want this to run on your cluster though, so go to the dropdown arrow at the end of the Run Environment cell and open it to expose the "Edit Hpc node" menu which opens the Node Selector dialog:In this dialog you can enter (or pick from a list) the cluster head node name and then the number of processes you want to execute on the cluster and then hit OK and… you are done.3. Press F5 and watch your breakpoint get hit (after giving it some time for copying, remote execution, attachment and symbol resolution to take place).GOING DEEPERIn the MPI Cluster Debugger project properties above, you can see many additional properties to the Run Environment. They are all optional, but you may want to understand them in order to fine tune your cluster debugging. Read all about each one of these on the MSDN page Configuration Properties for the MPI Cluster Debugger.In the Node Selector dialog above you can see more options than just the Head Node name and Number of Process to run. They should be self-explanatory but I also cover them in depth in my screencast showing you an example of why you would choose to schedule processes per core versus per node. You can also read about these options on MSDN as part of the page How to: Configure and Launch the MPI Cluster Debugger.To read through an example that touches on MPI project creation, project properties, node selector, and also usage of MPI with OpenMP plus MPI with PPL, read the MSDN page Walkthrough: Launching the MPI Cluster Debugger in Visual Studio 2010.Happy MPI debugging!

• Common SOA Problems by C2B2

  - by JuergenKress

  SOA stands for Service Oriented Architecture and has only really come together as a concrete approach in the last 15 years or so, although the concepts involved have been around for longer. Oracle SOA Suite is based around the Service Component Architecture (SCA) devised by the Open SOA collaboration of companies including Oracle and IBM. SCA, as used in SOA suite, is designed as a way to crystallise the concepts of SOA into a standard which ensures that SOA principles like the separation of application and business logic are maintained. Orchestration or Integration? A common thing to see with many people who are beginning to either build a new SOA based infrastructure, or move an old system to be service oriented, is confusion in the purpose of SOA technologies like BPEL and enterprise service buses. For a lot of problems, orchestration tools like BPEL or integration tools like an ESB will both do the job and achieve the right objectives; however it’s important to remember that, although a hammer can be used to drive a screw into wood, that doesn’t mean it’s the best way to do it. Service Integration is the act of connecting components together at a low level, which usually results in a single external endpoint for you to expose to your customers or other teams within your organisation – a simple product ordering system, for example, might integrate a stock checking service and a payment processing service. Process Orchestration, however, is generally a higher level approach whereby the (often externally exposed) service endpoints are brought together to track an end-to-end business process. This might include the earlier example of a product ordering service and couple it with a business rules service and human task to handle edge-cases. A good (but not exhaustive) rule-of-thumb is that integrations performed by an ESB will usually be real-time, whereas process orchestration in a SOA composite might comprise processes which take a certain amount of time to complete, or have to wait pending manual intervention. BPEL vs BPMN For some, with pre-existing SOA or business process projects, this decision is effectively already made. For those embarking on new projects it’s certainly an important consideration for those using Oracle SOA software since, due to the components included in SOA Suite and BPM Suite, the choice of which to buy is determined by what they offer. Oracle SOA suite has no BPMN engine, whereas BPM suite has both a BPMN and a BPEL engine. SOA suite has the ESB component “Mediator”, whereas BPM suite has none. Decisions must be made, therefore, on whether just one or both process modelling languages are to be used. The wrong decision could be costly further down the line.

• Releasing the new Sample Browser Phone app

  - by Jialiang

  Originally posted on: http://geekswithblogs.net/Jialiang/archive/2014/06/05/releasing-the-new-sample-browser-phone-app.aspx Starting its journey in 2010, Sample Browser is achieving its tetralogy by releasing a Windows Phone version Sample Browser today. The new Windows Phone app is the fourth milestone of Sample Browser since we released the desktop version and the Visual Studio version in 2012 and the Windows Store version in 2013. This time, by providing a sample browser designed for a ‘walking’ platform in response to MVPs’ suggestions during last year’s MVP Global Summit, we are literally putting a world of code samples "at developers’ fingertips”. If you like to have a code gallery of over 7000 quality code samples in your pocket, then click here to download our Windows Phone Sample Browser and start a fantastic mobile experience. With Windows Phone version Sample Browser and the Internet, you can search for code samples on MSDN at anytime and anywhere you want, 24/7 and–even to bed. You can also check code sample details and share them with your friends. Compared to the other 3 pieces in the tetralogy (desktop version, Visual Studio version, and the Windows Store version), the Windows Phone version Sample Browser sells itself for convenience and instant connectivity. For those who need to reach code samples under mobile circumstances where no PCs is available, Windows Phone version Sample Browser will definitely be the right service you are seeking for. Aside from sharing samples via emails as the other 3 do, the Windows Phone version Sample Browser also allows you to share the sample via SMS and Near Field Communication (NFC).   What's Next Currently, the Windows Phone Sample Browser only supports online MSDN code searching, but we already plan to upgrade Sample Browser to allow users to do ‘Bing code search’, and add and manage their private code snippets.  We will also upgrade the app to universal app. Universal App is a new concept brought up in the Microsoft Build Developer Conference 2014. It is a new development model that allows for a single app to be deployed across multiple Windows devices such as Windows Phone, Windows 8.1, and XBox. Therefore, once we finish upgrading Sample Browser to a universal app, you can synchronize your own code snippets across different devices; You can also mark a code sample as favorite on your Windows Phone and continue to study the sample when you are on your desktop. By then, sharing data between platforms will be a piece of cake. Also, the user experience of Sample Browser on different platforms will be more consistent.  The best is yet to come!   We sincerely suggest you give Sample Browser a try (click here to download). If you love what you see in Sample Browser, please recommend it to your friends and colleagues. If you encounter any problems or have any suggestions for us, please contact us at [email protected]. Your precious opinions and comments are more than welcome.

• Microsoft Azure News: Capturing VM Images

  - by Herve Roggero

  Originally posted on: http://geekswithblogs.net/hroggero/archive/2014/05/21/microsoft-azure-news-capturing-vm-images.aspxIf you have a Virtual Machine (VM) in Microsoft Azure that has a specific configuration, it used to be difficult to clone that VM. You had to sysprep the VM, and clone the data disks. This was slow, prone to errors, and stopped you from being productive. No more! A new option, called Capture, allows you to easily select a VM, running or not. The capture will copy the OS disk and data disks and create a new image out of it automatically for you. This means you can now easily clone an entire VM without affecting productivity.  To capture a VM, simply browse to your Virtual Machines in the Microsoft Azure management website, select the VM you want to clone, and click on the Capture button at the bottom. A window will come up asking to name your image. It took less than 1 minute for me to build a clone of my server. And because it is stored as an image, I can easily create a new VM with it. So that’s what I did… And that took about 5 minutes total.  That’s amazing…  To create a new VM from your image, click on the NEW icon (bottom left), select Compute/Virtual Machine/From Gallery, and select My Images from the left menu when selecting an Image. You will find your newly created image. Because this is a clone, you will not be prompted for a new login; the user id/password is the same.

• Obtaining the correct Client IP address when a Physical Load Balancer and a Web Server Configured With Proxy Plug-in Are Between The Client And Weblogic

  - by adejuanc

  Some Load Balancers like Big-IP have build in interoperability with Weblogic Cluster, this means they know how Weblogic understand a header named 'WL-Proxy-Client-IP' to identify the original client ip.The problem comes when you have a Web Server configured with weblogic plug-in between the Load Balancer and the back-end weblogic servers - WL-Proxy-Client-IP this is not designed to go to Web server proxy plug-in. The plug-in will not use a WL-Proxy-Client-IP header that came in from the previous hop (which is this case is the Physical Load Balancer but could be anything), in order to prevent IP spoofing, therefore the plug-in won't pass on what Load Balancer has set for it.So unfortunately under this Architecture the header will be useless. To get the client IP from Weblogic you need to configure extended log format and create a custom field that gets the appropriate header containing the IP of the client.On WLS versions prior to 10.3.3 use these instructions:You can also create user-defined fields for inclusion in an HTTP access log file that uses the extended log format. To create a custom field you identify the field in the ELF log file using the Fields directive and then you create a matching Java class that generates the desired output. You can create a separate Java class for each field, or the Java class can output multiple fields. For a sample of the Java source for such a class, seeJava Class for Creating a Custom ELF Field to import weblogic.servlet.logging.CustomELFLogger;import weblogic.servlet.logging.FormatStringBuffer;import weblogic.servlet.logging.HttpAccountingInfo;/* This example outputs the X-Forwarded-For field into a custom field called MyOriginalClientIPField */public class MyOriginalClientIPField implements CustomELFLogger{ public void logField(HttpAccountingInfo metrics,  FormatStringBuffer buff) {   buff.appendValueOrDash(metrics.getHeader("X-Forwarded-For");  }}In this case we are using 'X-Forwarded-For' but it could be changed for the header that contains the data you need to use.Compile the class, jar it, and prepend it to the classpath.In order to compile and package the class: 1. Navigate to <WLS_HOME>/user_projects/domains/<SOME_DOMAIN>/bin2. Set up an environment by executing: $ . ./setDomainEnv.sh This will include weblogic.jar into classpath, in order to use any of the libraries included under package weblogic.*3. Compile the class by copying the content of the code above and naming the file as:MyOriginalClientIPField.java4. Run javac to compile the class.$javac MyOriginalClientIPField.java5. Package the compiled class into a jar file by executing:$jar cvf0 MyOriginalClientIPField.jar MyOriginalClientIPField.classExpected output is:added manifestadding: MyOriginalClientIPField.class(in = 711) (out= 711)(stored 0%)6. This will produce a file called:MyOriginalClientIPField.jar This way you will be able to get the real client IP when the request is passing through a Load Balancer and a Web server before reaching WLS. Since 10.3.3 it is possible to configure a specific header that WLS will check when getRemoteAddr is called. That can be set on the WebServer Mbean. In this case, set that to be X-Forwarded-For header coming from Load Balancer as well.

• Running Built-In Test Simulator with SOA Suite Healthcare 11g in PS4 and PS5

  - by Shub Lahiri, A-Team

  Background SOA Suite for Healthcare Integration pack comes with a pre-installed simulator that can be used as an external endpoint to generate inbound and outbound HL7 traffic on specified MLLP ports. This is a command-line utility that can be very handy when trying to build a complete end-to-end demo within a standalone, closed environment. The ant-based utility accepts the name of a configuration file as the command-line input argument. The format of this configuration file has changed between PS4 and PS5. In PS4, the configuration file was XML based and in PS5, it is name-value property based. The rest of this note highlights these differences and provides samples that can be used to run the first scenario from the product samples set. PS4 - Configuration File The sample configuration file for PS4 is shown below. The configuration file contains information about the following items: Directory for incoming and outgoing files for the host running SOA Suite Healthcare Polling Interval for the directory External Endpoint Logical Names External Endpoint Server Host Name and Ports Message throughput to be simulated for generating outbound messages Documents to be handled by different endpoints A copy of this file can be downloaded from here. PS5 - Configuration File The corresponding sample configuration file for PS5 is shown below. The configuration file contains similar information about the sample scenario but is not in XML format. It has name-value pairs specified in the form of a properties file. This sample file can be downloaded from here. Simulator Configuration Before running the simulator, the environment has to be set by defining the proper ANT_HOME and JAVA_HOME. The following extract is taken from a working sample shell script to set the environment: Also, as a part of setting the environment, template jndi.properties and logging.properties can be generated by using the following ant command: ant -f ant-b2bsimulator-util.xml b2bsimulator-prop Sample jndi.properties and logging.properties are shown below and can be modified, as needed. The jndi.properties contains information about connectivity to the local Weblogic Managed Server instance and the logging.properties file controls the amount of logging that can be generated from the running simulator process. Simulator Usage - Start and Stop The command syntax to launch the simulator via ant is the same in PS4 and PS5. Only the appropriate configuration file has to be supplied as the command-line argument, for example: ant -f ant-b2bsimulator-util.xml b2bsimulatorstart -Dargs="simulator1.hl7-config.xml" This will start the simulator and will keep running to provide an active external endpoint for SOA Healthcare Integration engine. To stop the simulator, a similar ant command can be used, for example: ant -f ant-b2bsimulator-util.xml b2bsimulatorstop

• How do I take responsibility for my code when colleague makes unnecessary improvements without notice?

  - by Jesslyn

  One of my teammates is a jack of all trades in our IT shop and I respect his insight. However, sometimes he reviews my code (he's second in command to our team leader, so that's expected) without a heads up. So sometimes he reviews my changes before they complete the end goal and makes changes right away... and has even broken my work once. Other times, he has made unnecessary improvements to some of my code that is 3+ months old. This annoys me for a few reasons: I am not always given a chance to fix my mistakes He has not taken the time to ask me what I was trying to accomplish when he is confused, which could affect his testing or changes I don't always think his code is readable Deadlines are not an issue and his current workload doesn't require any work in my projects other than reviewing my code changes. Anyways, I have told him in the past to please keep me posted if he sees something in my work that he wants to change so that I could take ownership of my code (maybe I should have said "shortcomings") and he's not been responsive. I fear that I may come off as aggressive when I ask him to explain his changes to me. He's just a quiet person who keeps to himself, but his actions continue. I don't want to banish him from making code changes (not like I could), because we are a team--but I want to do my part to help our team. Added clarifications: We share 1 development branch. I do not wait until all my changes complete a single task because I risk losing some significant work--so I make sure my changes build and do not break anything. My concern is that my teammate doesn't explain the reason or purpose behind his changes. I don't think he should need my blessing, but if we disagree on an approach I thought it would be best to discuss the pros and cons and make a decision once we both understand what is going on. I have not discussed this with our team lead yet as I would prefer to resolve personal disagreements without getting management involved unless it is necessary. Since my concern seemed more of personal issue than a threat to our work, I chose to not bother the team lead. I am working on code review process ideas--to help promote the benefits of more organized code reviews without making it all about my pet peeves.

• Generate MERGE statements from a table

  - by Bill Graziano

  We have a requirement to build a test environment where certain tables get reset from production every night.  These are mainly lookup tables.  I played around with all kinds of fancy solutions and finally settled on a series of MERGE statements.  And being lazy I didn’t want to write them myself.  The stored procedure below will generate a MERGE statement for the table you pass it.  If you have identity values it populates those properly.  You need to have primary keys on the table for the joins to be generated properly.  The only thing hard coded is the source database.  You’ll need to update that for your environment.  We actually used a linked server in our situation. CREATE PROC dba_GenerateMergeStatement (@table NVARCHAR(128) )ASset nocount on; declare @return int;PRINT '-- ' + @table + ' -------------------------------------------------------------'--PRINT 'SET NOCOUNT ON;--'-- Set the identity insert on for tables with identitiesselect @return = objectproperty(object_id(@table), 'TableHasIdentity')if @return = 1 PRINT 'SET IDENTITY_INSERT [dbo].[' + @table + '] ON; 'declare @sql varchar(max) = ''declare @list varchar(max) = '';SELECT @list = @list + [name] +', 'from sys.columnswhere object_id = object_id(@table)SELECT @list = @list + [name] +', 'from sys.columnswhere object_id = object_id(@table)SELECT @list = @list + 's.' + [name] +', 'from sys.columnswhere object_id = object_id(@table)-- --------------------------------------------------------------------------------PRINT 'MERGE [dbo].[' + @table + '] AS t'PRINT 'USING (SELECT * FROM [source_database].[dbo].[' + @table + ']) as s'-- Get the join columns ----------------------------------------------------------SET @list = ''select @list = @list + 't.[' + c.COLUMN_NAME + '] = s.[' + c.COLUMN_NAME + '] AND 'from INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk , INFORMATION_SCHEMA.KEY_COLUMN_USAGE cwhere pk.TABLE_NAME = @tableand CONSTRAINT_TYPE = 'PRIMARY KEY'and c.TABLE_NAME = pk.TABLE_NAMEand c.CONSTRAINT_NAME = pk.CONSTRAINT_NAMESELECT @list = LEFT(@list, LEN(@list) -3)PRINT 'ON ( ' + @list + ')'-- WHEN MATCHED ------------------------------------------------------------------PRINT 'WHEN MATCHED THEN UPDATE SET'SELECT @list = '';SELECT @list = @list + ' [' + [name] + '] = s.[' + [name] +'],'from sys.columnswhere object_id = object_id(@table)-- don't update primary keysand [name] NOT IN (SELECT [column_name] from INFORMATION_SCHEMA.TABLE_CONSTRAINTS pk , INFORMATION_SCHEMA.KEY_COLUMN_USAGE c where pk.TABLE_NAME = @table and CONSTRAINT_TYPE = 'PRIMARY KEY' and c.TABLE_NAME = pk.TABLE_NAME and c.CONSTRAINT_NAME = pk.CONSTRAINT_NAME)-- and don't update identity columnsand columnproperty(object_id(@table), [name], 'IsIdentity ') = 0 --print @list PRINT left(@list, len(@list) -3 )-- WHEN NOT MATCHED BY TARGET ------------------------------------------------PRINT ' WHEN NOT MATCHED BY TARGET THEN';-- Get the insert listSET @list = ''SELECT @list = @list + '[' + [name] +'], 'from sys.columnswhere object_id = object_id(@table)SELECT @list = LEFT(@list, LEN(@list) - 1)PRINT ' INSERT(' + @list + ')'-- get the values listSET @list = ''SELECT @list = @list + 's.[' +[name] +'], 'from sys.columnswhere object_id = object_id(@table)SELECT @list = LEFT(@list, LEN(@list) - 1)PRINT ' VALUES(' + @list + ')'-- WHEN NOT MATCHED BY SOURCEprint 'WHEN NOT MATCHED BY SOURCE THEN DELETE; 'PRINT ''PRINT 'PRINT ''' + @table + ': '' + CAST(@@ROWCOUNT AS VARCHAR(100));';PRINT ''-- Set the identity insert OFF for tables with identitiesselect @return = objectproperty(object_id(@table), 'TableHasIdentity')if @return = 1 PRINT 'SET IDENTITY_INSERT [dbo].[' + @table + '] OFF; 'PRINT ''PRINT 'GO'PRINT '';

• OData &ndash; The easiest service I can create

  - by Jon Dalberg

  I wanted to create an OData service with the least amount of code so I fired up Visual Studio and got cracking. I decided to serve up a list of naughty words and make them read-only. Create a new web project. I created an empty MVC 2 application but MVC is not required for OData. Add a new WCF Data Service to the project. I named mine NastyWords.svc since I’m serving up a list of nasty words. Add a class to expose via the service: NastyWord 1: [DataServiceKey("Word")] 2: public class NastyWord 3: { 4: public string Word { get; set; } 5: }   I need to be able to uniquely identify instances of NastyWords for the DataService so I used the DataServiceKey attribute with the “Word” property as the key. I could have added an “ID” property which would have uniquely identified them and would then not need the “DataServiceKey” attribute because the DataService would apply some reflection and heuristics to guess at which property would be the unique identifier. However, the words themselves are unique so adding an “ID” property would be redundantly repetitive. Then I created a data source to expose my NastyWord objects to the service. This is just a simple class with IQueryable<T> properties exposing the entities for my service: 1: public class NastyWordsDataSource 2: { 3: private static IList<NastyWord> words = new List<NastyWord> 4: { 5: new NastyWord{ Word="crap"}, 6: new NastyWord{ Word="darn"}, 7: new NastyWord{ Word="hell"}, 8: new NastyWord{ Word="shucks"} 9: }; 10:   11: public NastyWordsDataSource() 12: { 13: NastyWords = words.AsQueryable(); 14: } 15:   16: public IQueryable<NastyWord> NastyWords { get; private set; } 17: }   Now I can go to the NastyWords.svc class and tell it which data source to use and which entities to expose: 1: public class NastyWords : DataService<NastyWordsDataSource> 2: { 3: // This method is called only once to initialize service-wide policies. 4: public static void InitializeService(DataServiceConfiguration config) 5: { 6: config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); 7: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 8: } 9: }   Compile and browse to my NastWords.svc and weep with joy Now I can query my service just like any other OData service. Next time, I’ll modify this service to allow updates to sent so I can build up my list of nasty words. Enjoy!

When looking into the future, the discussion starts with a historical look to better prepare for what comes next.   As shown in the image below, one of the next frontiers after mobile and cloud integration is a deeper level of direct "enterprise to customer" interaction.  Much of this relates to the Internet of Things.  Examples of IoT from the perspective of SOA and integration is also covered in the session. For example, early adopter Turkcell and their tracking of mobile phone users as they move from point A to B to C is shown in the image the right.   As you look into more "smart services" such as Location-Based Services, how "future ready" is your application infrastructure?  . . . Check out the replay by clicking the video image below to learn about these three challenges and solution including how to "future ready" your application infrastructure:

• Creating a shared library that might be used with desktop applications and web projects

  - by dreza

  I have been involved in a number of MVC.NET and c# desktop projects in our company over the last year or so while also managing to kept my nose poked into other projects (in a read-only learning capacity of course). From this I've noticed that across the various projects and teams there is a-lot of functionality that has been well designed against good interfaces and abstractions. Because we tend to like our own work at times, I noticed a couple of projects had the exact same class, method copied into it as it had obviously worked on one and so was easily moved to a new project (probably by the same developer who originally wrote it) I mentioned this fact in one of our programmer meetings we have occasionally and suggested we pull some of this functionality into a core company library that we can build up over time and use across multiple projects. Everyone agreed and I started looking into this possibility. However, I've come across a stumbling block pretty early on. Our team primarily focuses on MVC at the moment and we have projects mainly in 2.0 but are starting to branch to 3.0. We also have a number of desktop applications that might benefit from some shared classes and basic helper methods. Initially when creating this DLL I included some shared classes that could be used across any project type (Web, Client etc) but then I started looking at adding some shared modules that would be useful in our MVC applications only. However this meant I had to include a reference to some Microsoft Web DLL's in order to leverage some of the classes I was creating (at this stage MVC 2.0). Now my issue is that we have a shared DLL that has references to web specific libraries that could also possibly be used in a client application. Not only that, our DLL referenced initially MVC 2.0 and we will eventually move onto MVC 3.0 for all projects. But alot of the classes in this library I expect to still be relevant to MVC 3 etc Our code within this DLL is separated into it's own namespaces such as: CompanyDLL.Primitives CompanyDLL.Web.Mvc CompanyDLL.Helpers etc etc So, my questions are: Is it OK to do a shared library like this, or if we have web specific features in it should we create a separate web DLL only targeted at a specific framework or MVC version? If it's OK, what kind of issues might we face when using the library that references MVC 2 in a MVC 3 project for example. I would be thinking that we might run into some sort of compatibility issue, or even issues where the developers using the library doesn't realize they need MVC 2.0 libraries. They might only want to use some of the generic classes etc The concept seemed like a good idea at the time, but I'm starting to think maybe it's not really a practical solution. But the number of times I've seen copied classes and methods across projects because they are proven tested code is a bit unnerving to be perfectly honest!

• The Growing Importance of Network Virtualization

  - by user12608550

  The Growing Importance of Network Virtualization We often focus on server virtualization when we discuss cloud computing, but just as often we neglect to consider some of the critical implications of that technology. The ability to create virtual environments (or VEs [1]) means that we can create, destroy, activate and deactivate, and more importantly, MOVE them around within the cloud infrastructure. This elasticity and mobility has profound implications for how network services are defined, managed, and used to provide cloud services. It's not just servers that benefit from virtualization, it's the network as well. Network virtualization is becoming a hot topic, and not just for discussion but for companies like Oracle and others who have recently acquired net virtualization companies [2,3]. But even before this topic became so prominent, Solaris engineers were working on technologies in Solaris 11 to virtualize network services, known as Project Crossbow [4]. And why is network virtualization so important? Because old assumptions about network devices, topology, and management must be re-examined in light of the self-service, elasticity, and resource sharing requirements of cloud computing infrastructures. Static, hierarchical network designs, and inter-system traffic flows, need to be reconsidered and quite likely re-architected to take advantage of new features like virtual NICs and switches, bandwidth control, load balancing, and traffic isolation. For example, traditional multi-tier Web services (Web server, App server, DB server) that share net traffic over Ethernet wires can now be virtualized and hosted on shared-resource systems that communicate within a larger server at system bus speeds, increasing performance and reducing wired network traffic. And virtualized traffic flows can be monitored and adjusted as needed to optimize network performance for dynamically changing cloud workloads. Additionally, as VEs come and go and move around in the cloud, static network configuration methods cannot easily accommodate the routing and addressing flexibility that VE mobility implies; virtualizing the network itself is a requirement. Oracle Solaris 11 [5] includes key network virtualization technologies needed to implement cloud computing infrastructures. It includes features for the creation and management of virtual NICs and switches, and for the allocation and control of the traffic flows among VEs [6]. Additionally it allows for both sharing and dedication of hardware components to network tasks, such as allocating specific CPUs and vNICs to VEs, and even protocol-specific management of traffic. So, have a look at your current network topology and management practices in view of evolving cloud computing technologies. And don't simply duplicate the physical architecture of servers and connections in a virtualized environment…rethink the traffic flows among VEs and how they can be optimized using Oracle Solaris 11 and other Oracle products and services. [1] I use the term "virtual environment" or VE here instead of the more commonly used "virtual machine" or VM, because not all virtualized operating system environments are full OS kernels under the control of a hypervisor…in other words, not all VEs are VMs. In particular, VEs include Oracle Solaris zones, as well as SPARC VMs (previously called LDoms), and x86-based Solaris and Linux VMs running under hypervisors such as OEL, Xen, KVM, or VMware. [2] Oracle follows VMware into network virtualization space with Xsigo purchase; http://www.mercurynews.com/business/ci_21191001/oracle-follows-vmware-into-network-virtualization-space-xsigo [3] Oracle Buys Xsigo; http://www.oracle.com/us/corporate/press/1721421 [4] Oracle Solaris 11 Networking Virtualization Technology, http://www.oracle.com/technetwork/server-storage/solaris11/technologies/networkvirtualization-312278.html [5] Oracle Solaris 11; http://www.oracle.com/us/products/servers-storage/solaris/solaris11/overview/index.html [6] For example, the Solaris 11 'dladm' command can be used to limit the bandwidth of a virtual NIC, as follows: dladm create-vnic -l net0 -p maxbw=100M vnic0

Lynn Munsinger and her team worked hard to deliver this second part of the training as close to the release of the first installment as possible. This two part advanced ADF training provides you with a wealth of advanced ADF know-how and insight for you to adopt in a self-paced manner. Part 1 (though I am sure you have this bookmarked): http://tinyurl.com/advadf-part1 Part 2 (the new material): http://tinyurl.com/advadf-part2 Quoting Lynn: "This second installment provides you with all you need to know about regions, including best practices for implementing contextual events and other region communication patterns. It also covers the nitty-gritty details of building great looking user interfaces, such as how to work with (not against!) the ADF Faces layout components, how to build page templates and declarative components, and how to skin the application to your organization’s needs. It wraps up with an in-depth look at layout components, and a second helping of additional region considerations if you just can’t get enough. Like the first installment, the content for this course comes from Product Management. This 2nd eCourse compilation is a bit of a “Swan Song” for Patrice Daux, a long-time JDeveloper and ADF curriculum developer, who is retiring the end of this month.
