• Craftsmanship Tour: Day 3 &amp; 4 8th Light

  - by Liam McLennan

  Thursday morning the Illinois public transport system came through for me again. I took the Metra train north from Union Station (which was seething with inbound commuters) to Prairie Crossing (Libertyville). At Prairie Crossing I met Paul and Justin from 8th Light and then Justin drove us to the office. The 8th Light office is in an small business park, in a semi-rural area, surrounded by ponds. Upstairs there are two spacious, open areas for developers. At one end of the floor is Doug Bradbury’s walk-and-code station; a treadmill with a desk and computer so that a developer can get exercise at work. At the other end of the floor is a hammock. This irregular office furniture is indicative of the 8th Light philosophy, to pursue excellence without being limited by conventional wisdom. 8th Light have a wall covered in posters, each illustrating one person’s software craftsmanship journey. The posters are a fascinating visualisation of the similarities and differences between each of our progressions. The first thing I did Thursday morning was to create my own poster and add it to the wall. Over two days at 8th Light I did some pairing with the 8th Lighters and we shared thoughts on software development. I am not accustomed to such a progressive and enlightened environment and I found the experience inspirational. At 8th Light TDD, clean code, pairing and kaizen are deeply ingrained in the culture. Friday, during lunch, 8th Light hosted a ‘lunch and learn’ event. Paul Pagel lead us through a coding exercise using micro-pomodori. We worked in pairs, focusing on the pedagogy of pair programming and TDD. After lunch I recorded this interview with Paul Pagel and Justin Martin. We discussed 8th light, craftsmanship, apprenticeships and the limelight framework. Interview with Paul Pagel and Justin Martin My time at Didit, Obtiva and 8th Light has convinced me that I need to give up some of my independence and go back to working in a team. Craftsmen advance their skills by learning from each other, and I can’t do that working at home by myself. The challenge is finding the right team, and becoming a part of it.

• Friday Fun: Factory Balls – Christmas Edition

  - by Asian Angel

  Your weekend is almost here, but until the work day is over we have another fun holiday game for you. This week your job is to correctly decorate/paint the ornaments that go on the Christmas tree. Simple you say? Maybe, but maybe not! Factory Balls – Christmas Edition The object of the game is to correctly decorate/paint each Christmas ornament exactly as shown in the “sample image” provided for each level. What starts off as simple will quickly have you working to figure out the correct combination or sequence to complete each ornament. Are you ready? The first level serves as a tutorial to help you become comfortable with how to decorate/paint the ornaments. To move an ornament to a paint bucket or cover part of it with one of the helper items simply drag the ornament towards that area. The ornament will automatically move back to its’ starting position when the action is complete. First, a nice coat of red paint followed by covering the middle area with a horizontal belt. Once the belt is on move the ornament to the bucket of yellow paint. Next, you will need to remove the belt, so move the ornament back to the belt’s original position. One ornament finished! As soon as you complete decorating/painting an ornament, you move on to the next level and will be shown the next “sample Image” in the upper right corner. Starting with a coat of orange paint sounds good… Pop the little serrated edge cap on top… Add some blue paint… Almost have it… Place the large serrated edge cap on top… Another dip in the orange paint… And the second ornament is finished. Level three looks a little bit tougher…just work out your pattern of helper items & colors and you will definitely get it! Have fun decorating/painting those ornaments! Note: Starting with level four you will need to start using a combination of two helper items combined at times to properly complete the ornaments.

• Share OneNote 2010 Notebooks with OneNote 2007

  - by Matthew Guay

  OneNote is the new star of the Office Suite, and is included in every edition of Office 2010.  OneNote’s file format has been changed in the 2010 version, so here’s how you can still share your notebooks with those using OneNote 2007. Convert your OneNote Notebooks to 2007 Format If you open a notebook from OneNote 2010 in OneNote 2007, you may see this warning informing you that the notebook was created in a newer version of OneNote and cannot be opened. To make your 2010 notebooks compatible with OneNote 2007, you need to convert them inside OneNote 2010.  In OneNote 2010, open the File menu; this should open to the Info tab by default.  Select the Settings button beside the notebook you want to use in OneNote 2007, and select Properties. In the properties dialog, click “Convert to 2007”. You may see a warning that some formatting, content, and history that is incompatible with OneNote 2007 will be removed.  Click Ok to continue. OneNote will automatically convert everything in this notebook to 2007 format.  If your notebook is very large, this may take a few minutes. Once the conversion is completed, you can re-open the properties dialog to see the change.  The format is listed as OneNote 2007 format, and you have the option to convert to 2010.  Your 2007 formatted notebook is still fully usable in OneNote 2010, but you may not be able to use some of the newer features in it. Now that your notebook is in 2007 format, you can share it with OneNote 2007 users.  Here’s our notebook, the OneNote 2010 guide, open in OneNote 2007 after the conversion. Conclusion OneNote can be a great collaboration tool, and with this simple trick you can collaborate with those using older versions of OneNote.  Additionally, if you are currently running Office 2010 beta but plan to switch back to Office 2007 when the beta expires, then make sure to do this to any new notebooks you’ve created so you can still use them.

• Creating a bare bone web-browser: After the html parser, javascript parser, etc have done their work, how do I display the content of the webpage?

  - by aste123

  This is a personal project to learn computer programming. I took a look at this: https://www.udacity.com/course/viewer#!/c-cs262 The following is the approach taken in it: Abstract Syntax Tree is created. But javascript is still not completely broken down in order not to confuse with the html tags. Then the javascript interpreter is called on it. Javascript interpreter stores the text from the write() and document.write() to be used later. Then a graphics library in Python is called which will convert everything to a pdf file and then we convert it into png or jpeg and then display it. My Question: I want to display the actual text in a window (which I will design later) like firefox or chrome does instead of image files so that the data can be selected, copied, etc by the user of the browser. How do I accomplish this? In other words, what are the other elements of a bare bone web browser that I am missing? I would prefer to implement most of the stuff in C++ although if things seem too complicated I might go with Python to save time and create a prototype and later creating another bare bone browser in C++ and add more features. This is a project to learn more. I do realize we already have lots of reliable browsers like firefox, etc. The way I feel it is done: I think after all the broken down contents have been created by the parsers and interpreters, I will need to access them individually from within the window's code (like qt) and then decide upon a good way to display them. I am not sure if it is the way this should be done. Additions after useful comment by Kilian Foth: I found this page: http://friendlybit.com/css/rendering-a-web-page-step-by-step/ 14. A DOM tree is built out of the broken HTML 15. New requests are made to the server for each new resource that is found in the HTML source (typically images, style sheets, and JavaScript files). Go back to step 3 and repeat for each resource. 16. Stylesheets are parsed, and the rendering information in each gets attached to the matching node in the DOM tree 17. Javascript is parsed and executed, and DOM nodes are moved and style information is updated accordingly 18. The browser renders the page on the screen according to the DOM tree and the style information for each node 19. You see the page on the screen I need help with step 18. How do I do that? How much work do Webkit and Gecko do? I want to use a readymade layout renderer for step number 18 and not for anything that comes before that.

• The Complementary Roles of PLM and PIM

  - by Ulf Köster

  Oracle Product Value Chain Solutions (aka Enterprise PLM Solutions) are a comprehensive set of product management solutions that work together to provide Oracle customers with a broad array of capabilities to manage all aspects of product life: innovation, design, launch, and supply chain / commercialization processes beyond the capabilities and boundaries of traditional engineering-focused Product Lifecycle Management applications. They support companies with an integrated managed view across the product value chain: From Lab to Launch, From Farm to Fork, From Concept to Product to Customer, From Product Innovation to Product Design and Product Commercialization. Product Lifecycle Management (PLM) represents a broad suite of software solutions to improve product-oriented business processes and data. PLM success stories prove that PLM helps companies improve time to market, increase product-related revenue, reduce product costs, reduce internal costs and improve product quality. As a maturing suite of enterprise solutions, PLM is still evolving to realize the promise it can provide across all facets of a business and all phases of the product lifecycle. The vision for PLM includes everything from gathering early requirements for a product through multiple stages of the product lifecycle from product design, through commercialization and eventual product retirement or replacement. In discrete or process industries, PLM is typically more focused on Product Definition as items with respect to the technical view of a material or part, including specifications, bills of material and manufacturing data. With Agile PLM, this is specifically related to capabilities addressing Product Collaboration, Governance and Compliance, Product Quality Management, Product Cost Management and Engineering Collaboration. PLM today is mainly addressing key requirements in the early product lifecycle, in engineering changes or in the “innovation cycle”, and primarily adds value related to product design, development, launch and engineering change process. In short, PLM is the master for Product Definition, wherever manufacturing takes place. Product Information Management (PIM) is a product suite that has evolved in parallel to PLM. Product Information Management (PIM) can extend the value of PLM implementations by providing complementary tools and capabilities. More relevant in the area of Product Commercialization, the vision for PIM is to manage product information throughout an enterprise and supply chain to improve product-related knowledge management, information sharing and synchronization from multiple data sources. PIM success stories have shown the ability to provide multiple benefits, with particular emphasis on reducing information complexity and information management costs. Product Information in PIM is typically treated as the commercial view of a material or part, including sales and marketing information and categorization. PIM collects information from multiple manufacturing sites and multiple suppliers into its repository, but also provides integration tools to push the information back out to the other systems, serving as an active central repository with the aim to provide a holistic view on any product sold by a company (hence the name “Product Hub”). In short, PIM is the master of commercial Product Information. So PIM is quickly becoming mandatory because of its value in optimizing multichannel selling processes and relationships with customers, as you can see from the following table: Viewpoint PLM Current State PIM Key Benefits PIM adds to PLM Product Lifecycle Primarily R&D Front end Innovation Cycle Change process Primarily commercial / transactional state of lifecycle Provides a seamless information flow from design and manufacturing through the ultimate selling and servicing of products Data Primarily focused on “item” vs. “product” data Product structures Specifications Technical information Repository for all product information. Reaches out to entire enterprise and its various silos of product information and descriptions Provides a “trusted source” of accurate product information to the internal organization and trading partners Data Lifecycle Repository for all design iterations Historical information Released, current information, with version management and time stamping Provides a single location to track and audit historical product information Communication PLM release finished product to ERP PLM is the master for Product Definition Captures information from disparate sources, including in-house data stores Recognizes the reality of today’s data “mess” across information silos Provides the ability to package product information to its audience in the desired, relevant format to meet their exacting business requirements Departmental R&D Manufacturing Quality Compliance Procurement Strategic Marketing Focus on Marketing and Sales Gathering information from other Departments, multiple sites, multiple suppliers A singular enterprise solution that leverages existing information silos and data stores Supply Chain Multi-site internal collaboration Supplier collaboration Customer collaboration Works with customers, exchanges / data pools, and trading partners to provide relevant product information packaged the way the customer desires Provides ability to provide trading partners and internal customers with information in a manner they desire, continuously Tools Data Management Collaboration Innovation Management Cleansing Synchronization Hub functions Consistent, clean and complete commercial product information The goals of both PLM and PIM, put simply, are to help companies make more profit from their products. PLM and PIM solutions can be easily added as they share some of the same goals, while coming from two different perspectives: the definition of the product and the commercialization of the product. Both can serve as a form of product “system of record”, but take different approaches to delivering value. Oracle Product Value Chain solutions offer rich new strategies for executives to collectively leverage Agile PLM, Product Data Hub, together with Enterprise Data Quality for Products, and other industry leading Oracle applications to achieve further incremental value, like Oracle Innovation Management. This is unique on the market today.

• SQL SERVER – Automation Process Good or Ugly

  - by pinaldave

  This blog post is written in response to T-SQL Tuesday hosted by SQL Server Insane Asylum. The idea of this post really caught my attention. Automation – something getting itself done after the initial programming, is my understanding of the subject. The very next thought was – is it good or evil? The reality is there is no right answer. However, what if we quickly note a few things, then I would like to request your help to complete this post. We will start with the positive parts in SQL Server where automation happens. The Good If I start thinking of SQL Server and Automation the very first thing that comes to my mind is SQL Agent, which runs various jobs. Once I configure any task or job, it runs fine (till something goes wrong!). Well, automation has its own advantages. We all have used SQL Agent for so many things – backup, various validation jobs, maintenance jobs and numerous other things. What other kinds of automation tasks do you run in your database server? The Ugly This part is very interesting, because it can get really ugly(!). During my career I have found so many bad automation agent jobs. Client had an agent job where he was dropping the clean buffers every hour Client using database mail to send regular emails instead of necessary alert related emails The best one – A client used new Missing Index and Unused Index scripts in SQL Agent Job to follow suggestions 100%. Believe me, I have never seen such a badly performing and hard to optimize database. (I ended up dropping all non-clustered indexes on the development server and ran production workload on the development server again, then configured with optimal indexes). Shrinking database is performance killer. It should never be automated. SQL SERVER – Shrinking Database is Bad – Increases Fragmentation – Reduces Performance The one I hate the most is AutoShrink Database. It has given me hard time in my career quite a few times. SQL SERVER – SHRINKDATABASE For Every Database in the SQL Server Automation is necessary but common sense is a must when creating automation.

• Multiple file upload with asp.net 4.5 and Visual Studio 2012

  - by Jalpesh P. Vadgama

  This post will be part of Visual Studio 2012 feature series. In earlier version of ASP.NET there is no way to upload multiple files at same time. We need to use third party control or we need to create custom control for that. But with asp.net 4.5 now its possible to upload multiple file with file upload control. With ASP.NET 4.5 version Microsoft has enhanced file upload control to support HTML5 multiple attribute. There is a property called ‘AllowedMultiple’ to support that attribute and with that you can easily upload the file. So what we are waiting for!! It’s time to create one example. On the default.aspx file I have written following. <asp:FileUpload ID="multipleFile" runat="server" AllowMultiple="true" /> <asp:Button ID="uploadFile" runat="server" Text="Upload files" onclick="uploadFile_Click"/> Here you can see that I have given file upload control id as multipleFile and I have set AllowMultiple file to true. I have also taken one button for uploading file.For this example I am going to upload file in images folder. As you can see I have also attached event handler for button’s click event. So it’s time to write server side code for this. Following code is for the server side. protected void uploadFile_Click(object sender, EventArgs e) { if (multipleFile.HasFiles) { foreach(HttpPostedFile uploadedFile in multipleFile.PostedFiles) { uploadedFile.SaveAs(System.IO.Path.Combine(Server.MapPath("~/Images/"),uploadedFile.FileName)); Response.Write("File uploaded successfully"); } } } Here in the above code you can see that I have checked whether multiple file upload control has multiple files or not and then I have save that in Images folder of web application. Once you run the application in browser it will look like following. I have selected two files. Once I have selected and clicked on upload file button it will give message like following. As you can see now it has successfully upload file and you can see in windows explorer like following. As you can see it’s very easy to upload multiple file in ASP.NET 4.5. Stay tuned for more. Till then happy programming. P.S.: This feature is only supported in browser who support HTML5 multiple file upload. For other browsers it will work like normal file upload control in asp.net.

• SQL SERVER – Puzzle to Win Print Book – Explain Value of PERCENTILE_CONT() Using Simple Example

  - by pinaldave

  From last several days I am working on various Denali Analytical functions and it is indeed really fun to refresh the concept which I studied in the school. Earlier I wrote article where I explained how we can use PERCENTILE_CONT() to find median over here SQL SERVER – Introduction to PERCENTILE_CONT() – Analytic Functions Introduced in SQL Server 2012. Today I am going to ask question based on the same blog post. Again just like last time the intention of this puzzle is as following: Learn new concept of SQL Server 2012 Learn new concept of SQL Server 2012 even if you are on earlier version of SQL Server. On another note, SQL Server 2012 RC0 has been announced and available to download SQL SERVER – 2012 RC0 Various Resources and Downloads. Now let’s have fun following query: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, PERCENTILE_CONT(0.5) WITHIN GROUP (ORDER BY ProductID) OVER (PARTITION BY SalesOrderID) AS MedianCont FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY SalesOrderID DESC GO The above query will give us the following result: The reason we get median is because we are passing value .05 to PERCENTILE_COUNT() function. Now run read the puzzle. Puzzle: Run following T-SQL code: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, PERCENTILE_CONT(0.9) WITHIN GROUP (ORDER BY ProductID) OVER (PARTITION BY SalesOrderID) AS MedianCont FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY SalesOrderID DESC GO Observe the result and you will notice that MidianCont has different value than before, the reason is PERCENTILE_CONT function has 0.9 value passed. For first four value the value is 775.1. Now run following T-SQL code: USE AdventureWorks GO SELECT SalesOrderID, OrderQty, ProductID, PERCENTILE_CONT(0.1) WITHIN GROUP (ORDER BY ProductID) OVER (PARTITION BY SalesOrderID) AS MedianCont FROM Sales.SalesOrderDetail WHERE SalesOrderID IN (43670, 43669, 43667, 43663) ORDER BY SalesOrderID DESC GO Observe the result and you will notice that MidianCont has different value than before, the reason is PERCENTILE_CONT function has 0.1 value passed.

• A Small Utility to Delete Files recursively by Date

  - by Rick Strahl

  It's funny, but for me the following seems to be a recurring theme: Every few months or years I end up with a host of files on my server that need pruning selectively and often under program control. Today I realized that my SQL Server logs on my server were really piling up and nearly ran my backup drive out of drive space. So occasionally I need to check on that server drive and clean out files. Now with a bit of work this can be done with PowerShell or even a complicated DOS batch file, but heck, to me it's always easier to just create a small Console application that handles this sort of thing with a full command line parser and a few extra options, plus in the end I end up with code that I can actually modify and add features to as is invariably the case. No more searching for a script each time :-) So for my typical copy needs the requirements are: Need to recursively delete files Need to be able to specify a filespec (ie. *.bak) Be able to specify a cut off date before which to delete files And it'd be nice to have an option to send files to the Recycle bin just in case for operator error :-)(and yes that came in handy as I blew away my entire database backup folder by accident - oops!) The end result is a small Console file copy utility that I popped up on Github: https://github.com/RickStrahl/DeleteFiles The source code is up there along with the binary file you can just run. Creating DeleteFiles It's pretty easy to create a simple utility like DeleteFiles of course, so I'm not going to spend any talking about how it works. You can check it out in the repository or download and compile it. The nice thing about using a full programming language like C over something like PowerShell or batch file is that you can make short work of the recursive tree walking that's required to make this work. There's very little code, but there's also a very small, self-contained command line parser in there that might be useful that can be plugged into any project - I've been using it quite a bit for just about any Console application I've been building. If you're like me and don't have the patience or the persistence (that funky syntax requires some 'sticking with it' that I simply can't get over) to get into Powershell coding, having an executable file that I can just copy around or keep in my Utility directory is the only way I'll ever get to reuse this functionality without going on a wild search each time :-) Anyway, hope some of you might find this useful. © Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows  CSharp   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Do I need to match hardware on a Mac to my PC to get the same user experience?

  - by Darth

  I've been playing around with the thought of moving from a PC to a Mac. if you don't want to read this, skip to the "upgrade options" My current setup Most of my time I spent moving back and forth between Linux and Windows. During the last upgrade to Vista, I got myself pc with Core 2 Quad, 8GB of RAM and GeForce 9800GTX+. Currently I'm running dual boot between Ubuntu 10.04 and Windows Vista x64. Most of my work, around 80%, I can do on Ubuntu, which is mostly Ruby/Java programming. If that was all I needed, Ubuntu would be really great. However, I also do quite a lot of Photography and Design, which forces me to use Adobe software (not only Photoshop). I also work with Wacom Intuos4 tablet, which doesn't really have great support on Linux machines. I've tried virtualization both ways (Linux in Win and Win in Linux), but neither was anywhere near satisfying. These are those of many many reasons I want to move to OS X. Upgrade options This is how I see my upgrade options: Mac Mini - cheapest solution, but worst performance iMac - more expensive, better performing with second LCD for free Mac Pro - could match my current PC performance, currently outside of the price range When I compare the Mac hardware vs my current PC, it will be always worse, unless I decide to pump in a lot of money. The question that comes to my head, do I need to match my current PC hardware to get the same user experience with a Mac? If I look at it from the Vista point of view, 2GB RAM is as low as it gets, 4GB is usable ... and the 8GB runs very smoothly. PC HW != Mac HW? If I bought the Mac Mini for roughly the same price I paid for my PC (Core 2 Quad with 8GB RAM), I'd get Core 2 Duo with 4GB RAM. But I don't want to run Vista on it, so I can't compare the hardware directly. Say that I want to do the same things on the Mac Mini as I do on my PC, eg. open up 50 tabs in Google Chrome and start working with a large PSD in Photoshop (couple hundred MB), would running on Mac OS X compensate for the lower hardware performance? My point is, that if I'm about to upgrade, I wouldn't like to upgrade to hardware that runs a lot slower. Good analogy for this is Vista vs Ubuntu, where you can run Ubuntu smoothly on a low end laptop, but in Vista, you'd be happy to open a browser. Does the same principle apply to OS X?

• CQRS - Benefits

  - by Dylan Smith

  Thanks to all the comments and feedback from the last post I think I have a better understanding now of the benefits of CQRS (separate from the benefits of Event Sourcing). I’m going to try and sum it up here, and point out some areas where I could still use some advice: CQRS Benefits Sounds like the primary benefit of CQRS as an architecture is it allows you to create a simpler domain model by sucking out everything related to queries. I can definitely see the benefit to this, in general the domain logic related to commands is the high-value behavior in the software, but the logic required to service the queries would add a lot of low-value “noise” to the domain model that would dilute the high-value (command) behavior – sorting, paging, filtering, pre-fetch paths, etc. Also the most appropriate domain structure for implementing commands might not be the most optimal for implementing queries. To paraphrase Greg, this usually results in a domain model that is mediocre at both, piss-poor at one, or more likely piss-poor at both commands and queries. Not only will you be able to simplify your domain model by pulling out all the query logic, but at least a handful of commands in most systems will probably be “pass-though” type commands with little to no logic that just generate events. If these can be implemented directly in the command-handler and never touch the domain model, this allows you to slim down the domain model even more. Also, if you were to do event sourcing without CQRS, you no longer have a database containing the current state (only the domain model would) which makes it difficult (or impossible) to support ad-hoc querying and/or reporting that is common in most business software. Of course CQRS provides some great scalability benefits, not only scalability but I have to assume that it provides extremely low latency for most operations, especially if you have an asynchronous event bus. I know Greg says that you get a 3x scaling (Commands, Queries, Client) of your ability to perform parallel development, but IMHO, it seems like it only provides 1.5x scaling since even without CQRS you’re going to have your client loosely coupled to your domain - which is still a great benefit to be able to realize. Questions / Concerns If all the queries against an aggregate get pulled out to the Query layer, what if the only commands for that aggregate can be handled in a “pass-through” manner with the command handler directly generating events. Is it possible to have an aggregate that isn’t modeled in the domain model? Are there any issues or downsides to this? I know in the feedback from my previous posts it was suggested that having one domain model handling both commands and queries requires implementing a lot of traversals between objects that wouldn’t be necessary if it was only servicing commands. My question is, do you include traversals in your domain model based on the needs of the code, or based on the conceptual domain model? If none of my Commands require a Customer.Orders traversal, but the conceptual domain includes the concept of a set of orders belonging to a customer – should I model that in my domain model or not? I like the idea of using the Query side of the architecture as a place to put junior devs where the risk of them screwing something up has minimal impact. But I’m not sold on the idea that you can actually outsource it. Like I said in one of my comments on my previous post, the code to handle a query and generate DTO’s is going to be dead simple, but the code to process events and apply them to the tables on the query side is going to require a significant amount of domain knowledge to know which events to listen for to update each of the de-normalized tables (and what changes need to be made when each event is processed). I don’t know about everybody else, but having Indian/Russian/whatever outsourced developers have to do anything that requires significant domain knowledge has never been successful in my experience. And if you need to spec out for each new query which events to listen to and what to do with each one, well that’s probably going to be just as much work to document as it would be to just implement it. Greg made the point in a comment that doing an aggregate query like “Total Sales By Customer” is going to be inefficient if you use event sourcing but not CQRS. I don’t understand why that would be the case. I imagine in that case you’d simply have a method/property on the Customer object that calculated total sales for that customer by enumerating over the Orders collection. Then the application services layer would generate DTO’s off of the Customers collection that included say the CustomerID, CustomerName, TotalSales, or whatever the case may be. As long as you use a snapshotting implementation, I don’t see why that would be anymore inefficient in a DDD+Event Sourcing implementation than in a typical DDD implementation. Like I mentioned in my last post I still have some questions about query logic that haven’t been answered yet, but before I start asking those I want to make sure I have a strong grasp on what benefits CQRS provides.  My main concern with the query logic was that I know I could just toss it all into the query side, but I was concerned that I would be losing the benefits of using CQRS in the first place if I did that.  I want to elaborate more on this though with some example situations in an upcoming post.

• Multicast delegates in c#

  - by Jalpesh P. Vadgama

  In yesterday’s post We learn about Delegates and how we can use delegates in C#. In today’s blog post we are going to learn about Multicast delegates. What is Multicast Delegates? As we all know we can assign methods as object to delegate and later on we can call that method with the help delegates. We can also assign more then methods to delegates that is called Multicast delegates. It’s provide functionality to execute more then method at a time. It’s maintain delegates as invocation list (linked list). Let’s understands that via a example. We are going to use yesterday’s example and then we will extend that code multicast delegates. Following code I have written to demonstrate the multicast delegates. using System; namespace Delegates { class Program { public delegate void CalculateNumber(int a, int b); static void Main(string[] args) { int a = 5; int b = 5; CalculateNumber addNumber = new CalculateNumber(AddNumber); CalculateNumber multiplyNumber = new CalculateNumber(MultiplyNumber); CalculateNumber multiCast = (CalculateNumber)Delegate.Combine (addNumber, multiplyNumber); multiCast.Invoke(a,b); Console.ReadLine(); } public static void AddNumber(int a, int b) { Console.WriteLine("Adding Number"); Console.WriteLine(5 + 6); } public static void MultiplyNumber(int a, int b) { Console.WriteLine("Multiply Number"); Console.WriteLine(5 + 6); } } } As you can see in the above code I have created two method one for adding two numbers and another for multiply two number. After that I have created two same CalculateNumber delegates addNumber and multiplyNumber then I have create a multicast delegates multiCast with combining two delegates. Now I want to call this both method so I have used Invoke method to call this delegates. As now our code is let’s run the application. Following is a output as expected. As you can we can execute multiple methods with multicast delegates the only thing you need to take care is that we need to type for both delegates. That’s it. Hope you like it. Stay tuned for more.. Till then happy programming.

• Oracle Database 12c Spatial: Vector Performance Acceleration

  - by Okcan Yasin Saygili-Oracle

  Most business information has a location component, such as customer addresses, sales territories and physical assets. Businesses can take advantage of their geographic information by incorporating location analysis and intelligence into their information systems. This allows organizations to make better decisions, respond to customers more effectively, and reduce operational costs – increasing ROI and creating competitive advantage. Oracle Database, the industry’s most advanced database,  includes native location capabilities, fully integrated in the kernel, for fast, scalable, reliable and secure spatial and massive graph applications. It is a foundation for deploying enterprise-wide spatial information systems and locationenabled business applications. Developers can extend existing Oracle-based tools and applications, since they can easily incorporate location information directly in their applications, workflows, and services. Spatial Features The geospatial data features of Oracle Spatial and Graph option support complex geographic information systems (GIS) applications, enterprise applications and location services applications. Oracle Spatial and Graph option extends the spatial query and analysis features included in every edition of Oracle Database with the Oracle Locator feature, and provides a robust foundation for applications that require advanced spatial analysis and processing in the Oracle Database. It supports all major spatial data types and models, addressing challenging business-critical requirements from various industries, including transportation, utilities, energy, public sector, defense and commercial location intelligence. Network Data Model Graph Features The Network Data Model graph explicitly stores and maintains a persistent data model withnetwork connectivity and provides network analysis capability such as shortest path, nearest neighbors, within cost and reachability. It loads partitioned networks into memory on demand, overcomingthe limitations of in-memory analysis. Partitioning massive networks into manageable sub-networkssimplifies the network analysis. RDF Semantic Graph Features RDF Semantic Graph has native support for World Wide Web Consortium standards. It has open, scalable, and secure features for storing RDF/OWL ontologies anddata; native inference with OWL 2, SKOS and user-defined rules; and querying RDF/OWL data withSPARQL 1.1, Java APIs, and SPARQLgraph patterns in SQL. Video: Oracle Spatial and Graph Overview Oracle spatial is embeded on oracle database product. So ,we can use oracle installer (OUI).The Oracle Universal Installer (OUI) is used to install Oracle Database software. OUI is a graphical user interface utility that enables you to view the Oracle software that is installed on your machine, install new Oracle Database software, and delete Oracle software that you no longer need to use. Online Help is available to guide you through the installation process. One of the installation options is to create a database. If you select database creation, OUI automatically starts Oracle Database Configuration Assistant (DBCA) to guide you through the process of creating and configuring a database. If you do not create a database during installation, you must invoke DBCA after you have installed the software to create a database. You can also use DBCA to create additional databases. For installing Oracle Database 12c you may check the Installing Oracle Database Software and Creating a Database tutorial under the Oracle Database 12c 2-Day DBA Series.You can always check if spatial is available in your database using  "select comp_id, version, status, comp_name from dba_registry where comp_id='SDO';"   One of the most notable improvements with Oracle Spatial and Graph 12c can be seen in performance increases in vector data operations. Enabling the Spatial Vector Acceleration feature (available with the Spatial option) dramatically improves the performance of commonly used vector data operations, such as sdo_distance, sdo_aggr_union, and sdo_inside. With 12c, these operations also run more efficiently in parallel than in prior versions through the use of metadata caching. For organizations that have been facing processing limitations, these enhancements enable developers to make a small set of configuration changes and quickly realize significant performance improvements. Results include improved index performance, enhanced geometry engine performance, optimized secondary filter optimizations for Spatial operators, and improved CPU and memory utilization for many advanced vector functions. Vector performance acceleration is especially beneficial when using Oracle Exadata Database Machine and other large-scale systems. Oracle Spatial and Graph vector performance acceleration builds on general improvements available to all SDO_GEOMETRY operations in these areas: Caching of index metadata, Concurrent update mechanisms, and Optimized spatial predicate selectivity and cost functions. These optimizations enable more efficient use of: CPU, Memory, and Partitioning Resulting in substantial query performance improvements.UsageTo accelerate the performance of spatial operators, it is recommended that you set the SPATIAL_VECTOR_ACCELERATION database system parameter to the value TRUE. (This parameter is authorized for use only by licensed Oracle Spatial users, and its default value is FALSE.) You can set this parameter for the whole system or for a single session. To set the value for the whole system, do either of the following:Enter the following statement from a suitably privileged account:   ALTER SYSTEM SET SPATIAL_VECTOR_ACCELERATION = TRUE;Add the following to the database initialization file (xxxinit.ora):   SPATIAL_VECTOR_ACCELERATION = TRUE;To set the value for the current session, enter the following statement from a suitably privileged account:   ALTER SESSION SET SPATIAL_VECTOR_ACCELERATION = TRUE; Checkout the complete list of new features on Oracle.com @ http://www.oracle.com/technetwork/database/options/spatialandgraph/overview/index.html Spatial and Graph Data Sheet (PDF) Spatial and Graph White Paper (PDF)

• What have my fellow Delphi programmers done to make Eclipse/Java more like Delphi?

  - by Robert Oschler

  I am a veteran Delphi programmer working on my first real Android app. I am using Eclipse and Java as my development environment. The thing I miss the most of course is Delphi's VCL components and the associated IDE tools for design-time editing and code creation. Fortunately I am finding Eclipse to be one hell of an IDE with it's lush context sensitive help, deep auto-complete and code wizard facilities, and other niceties. This is a huge double treat since it is free. However, here is an example of something in the Eclipse/Java environment that will give a Delphi programmer pause. I will use the simple case of adding an "on-click" code stub for an OK button. DELPHI Drop button on a form Double-click button on form and fill in the code that will fire when the button is clicked ECLIPSE Drop button on layout in the graphical XML file editor Add the View.OnClickListener interface to the containing class's "implements" list if not there already. (Command+1 on Macs, Ctrl + 1 on PCs I believe). Use Eclipse to automatically add the code stub for unimplemented methods needed to support the View.OnClickListener interface, thus creating the event handler function stub. Find the stub and fill it in. However, if you have more than one possible click event source then you will need to inspect the View parameter to see which View element triggered the OnClick() event, thus requiring a case statement to handle multiple click event sources. NOTE: I am relatively new to Eclipse/Java so if there is a much easier way of doing this please let me know. Now that work flow isn't all that terrible, but again, that's just the simplest of use cases. Ratchet up the amount of extra work and thinking for a more complex component (aka widget) and the large number of properties/events it might have. It won't be long before you miss dearly the Delphi intelligent property editor and other designers. Eclipse tries to cover this ground by having an extensive list of properties in the menu that pops up when you right-click over a component/widget in the XML graphical layout editor. That's a huge and welcome assist but it's just not even close to the convenience of the Delphi IDE. Let me be very clear. I absolutely am not ranting nor do I want to start a Delphi vs. Java ideology discussion. Android/Eclipse/Java is what it is and there is a lot that impresses me. What I want to know is what other Delphi programmers that made the switch to the Eclipse/Java IDE have done to make things more Delphi like, and not just to make component/widget event code creation easier but any programming task. For example: Clever tips/tricks Eclipse plugins you found other ideas? Any great blog posts or web resources on the topic are appreciated too. -- roschler

• Getting Started with Prism (aka Composite Application Guidance for WPF and Silverlight)

  - by dotneteer

  Overview Prism is a framework from the Microsoft Patterns and Practice team that allow you to create WPF and Silverlight in a modular way. It is especially valuable for larger projects in which a large number of developers can develop in parallel. Prism achieves its goal by supplying several services: · Dependency Injection (DI) and Inversion of control (IoC): By using DI, Prism takes away the responsibility of instantiating and managing the life time of dependency objects from individual components to a container. Prism relies on containers to discover, manage and compose large number of objects. By varying the configuration, the container can also inject mock objects for unit testing. Out of the box, Prism supports Unity and MEF as container although it is possible to use other containers by subclassing the Bootstrapper class. · Modularity and Region: Prism supplies the framework to split application into modules from the application shell. Each module is a library project that contains both UI and code and is responsible to initialize itself when loaded by the shell. Each window can be further divided into regions. A region is a user control with associated model. · Model, view and view-model (MVVM) pattern: Prism promotes the user MVVM. The use of DI container makes it much easier to inject model into view. WPF already has excellent data binding and commanding mechanism. To be productive with Prism, it is important to understand WPF data binding and commanding well. · Event-aggregation: Prism promotes loosely coupled components. Prism discourages for components from different modules to communicate each other, thus leading to dependency. Instead, Prism supplies an event-aggregation mechanism that allows components to publish and subscribe events without knowing each other. Architecture In the following, I will go into a little more detail on the services provided by Prism. Bootstrapper In a typical WPF application, application start-up is controls by App.xaml and its code behind. The main window of the application is typically specified in the App.xaml file. In a Prism application, we start a bootstrapper in the App class and delegate the duty of main window to the bootstrapper. The bootstrapper will start a dependency-injection container so all future object instantiations are managed by the container. Out of box, Prism provides the UnityBootstrapper and MefUnityBootstrapper abstract classes. All application needs to either provide a concrete implementation of one of these bootstrappers, or alternatively, subclass the Bootstrapper class with another DI container. A concrete bootstrapper class must implement the CreateShell method. Its responsibility is to resolve and create the Shell object through the DI container to serve as the main window for the application. The other important method to override is ConfigureModuleCatalog. The bootstrapper can register modules for the application. In a more advance scenario, an application does not have to know all its modules at compile time. Modules can be discovered at run time. Readers to refer to one of the Open Modularity Quick Starts for more information. Modules Once modules are registered with or discovered by Prism, they are instantiated by the DI container and their Initialize method is called. The DI container can inject into a module a region registry that implements IRegionViewRegistry interface. The module, in its Initialize method, can then call RegisterViewWithRegion method of the registry to register its regions. Regions Regions, once registered, are managed by the RegionManager. The shell can then load regions either through the RegionManager.RegionName attached property or dynamically through code. When a view is created by the region manager, the DI container can inject view model and other services into the view. The view then has a reference to the view model through which it can interact with backend services. Service locator Although it is possible to inject services into dependent classes through a DI container, an alternative way is to use the ServiceLocator to retrieve a service on demard. Prism supplies a service locator implementation and it is possible to get an instance of the service by calling: ServiceLocator.Current.GetInstance<IServiceType>() Event aggregator Prism supplies an IEventAggregator interface and implementation that can be injected into any class that needs to communicate with each other in a loosely-coupled fashion. The event aggregator uses a publisher/subscriber model. A class can publishes an event by calling eventAggregator.GetEvent<EventType>().Publish(parameter) to raise an event. Other classes can subscribe the event by calling eventAggregator.GetEvent<EventType>().Subscribe(EventHandler, other options). Getting started The easiest way to get started with Prism is to go through the Prism Hands-On labs and look at the Hello World QuickStart. The Hello World QuickStart shows how bootstrapper, modules and region works. Next, I would recommend you to look at the Stock Trader Reference Implementation. It is a more in depth example that resemble we want to set up an application. Several other QuickStarts cover individual Prism services. Some scenarios, such as dynamic module discovery, are more advanced. Apart from the official prism document, you can get an overview by reading Glen Block’s MSDN Magazine article. I have found the best free training material is from the Boise Code Camp. To be effective with Prism, it is important to understands key concepts of WPF well first, such as the DependencyProperty system, data binding, resource, theme and ICommand. It is also important to know your DI container of choice well. I will try to explorer these subjects in depth in the future. Testimony Recently, I worked on a desktop WPF application using Prism. I had a wonderful experience with Prism. The Prism is flexible enough even in the presence of third party controls such as Telerik WPF controls. We have never encountered any significant obstacle.

• JCP.Next - Early Adopters of JCP 2.8

  - by Heather VanCura

  JCP.Next is a series of three JSRs (JSR 348, JSR 355 and JSR 358), to be defined through the JCP process itself, with the JCP Executive Committee serving as the Expert Group. The proposed JSRs will modify the JCP's processes  - the Process Document and Java Specification Participation Agreement (JSPA) and will apply to all new JSRs for all Java platforms.   The first - JCP.next.1, or more formally JSR 348, Towards a new version of the Java Community Process - was completed and put into effect in October 2011 as JCP 2.8. This focused on a small number of simple but important changes to make our process more transparent and to enable broader participation. We're already seeing the benefits of these changes as new and existing JSRs adopt the new requirements. The second - JSR 355, Executive Committee Merge, is also Final. You can read the JCP 2.9 Process Document .  As part of the JSR 355 Final Release, the JCP Executive Committee published revisions to the JCP Process Document (version 2.9) and the EC Standing Rules (version 2.2).  The changes went into effect following the 2012 EC Elections in November. The third JSR 358, A major revision of the Java Community Process was submitted in June 2012.  This JSR will modify the Java Specification Participation Agreement (JSPA) as well as the Process Document, and will tackle a large number of complex issues, many of them postponed from JSR 348. For these reasons, the JCP EC (acting as the Expert Group for this JSR), expects to spend a considerable amount of time working on. The JSPA is defined by the JCP as "a one-year, renewable agreement between the Member and Oracle. The success of the Java community depends upon an open and transparent JCP program.  JSR 358, A major revision of the Java Community Process, is now in process and can be followed on java.net. The following JSRs and Spec Leads were the early adopters of JCP 2.8, who voluntarily migrated their JSRs from JCP 2.x to JCP 2.8 or above.  More candidates for 2012 JCP Star Spec Leads! JSR 236, Concurrency Utilities for Java EE (Anthony Lai/Oracle), migrated April 2012 JSR 308, Annotations on Java Types (Michael Ernst, Alex Buckley/Oracle), migrated September 2012 JSR 335, Lambda Expressions for the Java Programming Language (Brian Goetz/Oracle), migrated October 2012 JSR 337, Java SE 8 Release Contents (Mark Reinhold/Oracle) – EG Formation, migrated September 2012 JSR 338, Java Persistence 2.1 (Linda DeMichiel/Oracle), migrated January 2012 JSR 339, JAX-RS 2.0: The Java API for RESTful Web Services (Santiago Pericas-Geertsen, Marek Potociar/Oracle), migrated July 2012 JSR 340, Java Servlet 3.1 Specification (Shing Wai Chan, Rajiv Mordani/Oracle), migrated August 2012 JSR 341, Expression Language 3.0 (Kin-man Chung/Oracle), migrated August 2012 JSR 343, Java Message Service 2.0 (Nigel Deakin/Oracle), migrated March 2012 JSR 344, JavaServer Faces 2.2 (Ed Burns/Oracle), migrated September 2012 JSR 345, Enterprise JavaBeans 3.2 (Marina Vatkina/Oracle), migrated February 2012 JSR 346, Contexts and Dependency Injection for Java EE 1.1 (Pete Muir/RedHat) – migrated December 2011

• Nokia vs. The World

  - by Michael B. McLaughlin

  I’m looking forward to the launch of the Nokia Lumia 920. Why? Well, it stacks up better than the competition for one thing. Then there’s also that security problem that certain other phones have. Mostly, though, it’s because I love my Lumia 900 and the 920, with Windows Phone 8, will be even better. Before I got my Lumia 900, I just took it as given that smart phone cameras couldn’t be good. The Lumia taught me that smart phone cameras can be good if the manufacturer treats them as an important component worth spending time and money on (rather than some thing that consumers expect such that they’d better throw one in). I’m extremely pleased with the quality of pictures that my Lumia 900 gives me as well as the range of settings it provides (you can delve in to tell it a film speed, an f-stop, and a whole range of other settings). And the image stabilization features in the Lumia 920 deliver far better results than the others. Nokia has had great maps for a long time and they continue to improve. Even better, they made a deal that puts many of their excellent maps into Windows Phone 8 itself. There are still Nokia-exclusive features such as Nokia City Lens, of course. But by giving the core OS a great set of fundamental map data and technologies, they help ensure that customers know that buying a Windows Phone 8 will give them a great map experience no matter who made the phone. I’ll be getting a 920, myself, but the HTC and Samsung devices that have been announced have some compelling features, too, and it’s great to know that people who buy one of these won’t need to worry about where their maps might lead them. I’m looking forward to the NFC capabilities and Qi wireless charging my Lumia 920 will have. With the availability of DirectX and C++ programming on Windows Phone 8, I’m also excited about all the great games that will be added to the Windows Phone environment. I love my Xbox Phone. I love my Office phone. I love my Facebook phone. I love my GPS phone. I love my camera phone. I love my SkyDrive phone. In short, I love my Windows Phone!

• What micro web-framework has the lowest overhead but includes templating

  - by Simon Martin

  I want to rewrite a simple small (10 page) website and besides a contact form it could be written in pure html. It is currently built with classic asp and Dreamweaver templates. The reason I'm not simply writing 10 html pages is that I want to keep the layout all in 1 place so would need either includes or a masterpage. I don't want to use Dreamweaver templates, or batch processing (like org-mode) because I want to be able to edit using notepad (or Visual Studio) because occasionally I might need to edit a file on the server (Go Daddy's IIS admin interface will let me edit text). I don't want to use ASP.NET MVC or WebForms (which I use in my day job) because I don't need all the overhead they bring with them when essentially I'm serving up 9 static files, 1 contact form and 1 list of clubs (that I aim to use jQuery to filter). The shared hosting package I have on Go Daddy seems to take a long time to spin up when serving aspx files. Currently the clubs page is driven from an MS SQL database that I try to keep up to date by manually checking the dojo locator on the main HQ pages and editing the entries myself, this is again way over the top. I aim to get a text file with the club details (probably in JSON or xml format) and use that as the source for the clubs page. There will need to be a bit of programming for this as the HQ site is unable to provide an extract / feed so something will have to scrape the site periodically to update my clubs persistence file. I'd like that to be automated - but I'm happy to have that triggered on a visit to the clubs page so I don't need to worry about scheduling a job. I would probably have a separate process that updates the persistence that has nothing to do with the rest of the site. Ideally I'd like to use Mercurial (or git) to publish, I know Bitbucket (and github) both serve static page sites so they wouldn't work in this scenario (dynamic pages and a contact form) but that's the model I'd like to use if there is such a thing. My requirements are: Simple templating system, 1 place to define header, footers, menu etc., that can be edited using just notepad. Very minimal / lightweight framework. I don't need a monster for 10 pages Must run either on IIS7 (shared Go Daddy Windows hosting) or other free host
