  • Great Surprise &ndash; MSDN Ultimate

    - by MarkPearl
    So, I attended the Microsoft Community Evening. The attendance was better than I was expecting for December and we had our first Programming Languages Meeting where Gary did a great presentation on an intro to Ruby. The best surprize of the evening happened when I was about to leave, Robert MacLean asked me how we did our MS licensing – the fact being that we were about to reach the end of our empower license with Microsoft and that I had no idea how we were going to afford upgrading it early next year. Well, out comes a Microsoft Visual Studio Ultimate with MSDN 12 month subscription. An absolute awesome gift – thanks Robert! Best gift ever!

  • Migrating SQL Server Databases – The DBA’s Checklist (Part 1)

    - by Sadequl Hussain
    It is a fact of life: SQL Server databases change homes. They move from one instance to another, from one version to the next, from old servers to new ones.  They move around as an organisation’s data grows, applications are enhanced or new versions of the database software are released. If not anything else, servers become old and unreliable and databases eventually need to find a new home. Consider the following scenarios: 1.     A new  database application is rolled out in a production server from the development or test environment 2.     A copy of the production database needs to be installed in a test server for troubleshooting purposes 3.     A copy of the development database is regularly refreshed in a test server during the system development life cycle 4.     A SQL Server is upgraded to a newer version. This can be an in-place upgrade or a side-by-side migration 5.     One or more databases need to be moved between different instances as part of a consolidation strategy. The instances can be running the same or different version of SQL Server 6.     A database has to be restored from a backup file provided by a third party application vendor 7.     A backup of the database is restored in the same or different instance for disaster recovery 8.     A database needs to be migrated within the same instance: a.     Files are moved from direct attached storage to storage area network b.    The same database is copied under a different name for another application Migrating SQL Server database applications is a complex topic in itself. There are a number of components that can be involved: jobs, DTS or SSIS packages, logins or linked servers are only few pieces of the puzzle. However, in this article we will focus only on the central part of migration: the installation of the database itself. Unless it is an in-place upgrade, typically the database is taken from a source server and installed in a destination instance.  Most of the time, a full backup file is used for the rollout. The backup file is either provided to the DBA or the DBA takes the backup and restores it in the target server. Sometimes the database is detached from the source and the files are copied to and attached in the destination. Regardless of the method of copying, moving, refreshing, restoring or upgrading the physical database, there are a number of steps the DBA should follow before and after it has been installed in the destination. It is these post database installation steps we are going to discuss below. Some of these steps apply in almost every scenario described above while some will depend on the type of objects contained within the database.  Also, the principles hold regardless of the number of databases involved. Step 1:  Make a copy of data and log files when attaching and detaching When detaching and attaching databases, ensure you have made copies of the data and log files if the destination is running a newer version of SQL Server. This is because once attached to a newer version, the database cannot be detached and attached back to an older version. Trying to do so will give you a message like the following: Server: Msg 602, Level 21, State 50, Line 1 Could not find row in sysindexes for database ID 6, object ID 1, index ID 1. Run DBCC CHECKTABLE on sysindexes. Connection Broken If you try to backup the attached database and restore it in the source, it will still fail. Similarly, if you are restoring the database in a newer version, it cannot be backed up or detached and put back in an older version of SQL. Unlike detach and attach method though, you do not lose the backup file or the original database here. When detaching and attaching a database, it is important you keep all the log files available along with the data files. It is possible to attach a database without a log file and SQL Server can be instructed to create a new log file, however this does not work if the database was detached when the primary file group was read-only. You will need all the log files in such cases. Step 2: Change database compatibility level Once the database has been restored or attached to a newer version of SQL Server, change the database compatibility level to reflect the newer version unless there is a compelling reason not to do so. When attaching or restoring from a previous version of SQL, the database retains the older version’s compatibility level.  The only time you would want to keep a database with an older compatibility level is when the code within your database is no longer supported by SQL Server. For example, outer joins with *= or the =* operators were still possible in SQL 2000 (with a warning message), but not in SQL 2005 anymore. If your stored procedures or triggers are using this form of join, you would want to keep the database with an older compatibility level.  For a list of compatibility issues between older and newer versions of SQL Server databases, refer to the Books Online under the sp_dbcmptlevel topic. Application developers and architects can help you in deciding whether you should change the compatibility level or not. You can always change the compatibility mode from the newest to an older version if necessary. To change the compatibility level, you can either use the database’s property from the SQL Server Management Studio or use the sp_dbcmptlevel stored procedure.   Bear in mind that you cannot run the built-in reports for databases from SQL Server Management Studio if you keep the database with an older compatibility level. The following figure shows the error message I received when trying to run the “Disk Usage by Top Tables” report against a database. This database was hosted in a SQL Server 2005 system and still had a compatibility mode 80 (SQL 2000).     Continues…

  • C++ skills higher than C skills?

    - by h0b0
    I feel that the often seen C/C++ doesn't really describe my skills in my CV. So I'm planning to separate it into advanced C++ knowledge and mediocre C skills. Do you think this is confusing for the reader? She could think: "C is a subset of C++, so what is this guy trying to tel me?" Well, what I'm trying to tell is: I have done several real world C++ projects while pure C projects where just a hobby thing. Do you agree that a skilled C++ programmer not necessarily is a qualified C guy or do you think that this switch is done easily?

  • JPA/EclipseLink multitenancy screencast

    - by alexismp
    I find JPA and in particular EclipseLink 2.3 to be particularly well suited to illustrate the concept of multitenancy, one of the key PaaS features en route for Java EE 7. Here's a short (5-minute) screencast showing GlassFish 3.1.1 (due out real soon now) and its EclipseLink 2.3 JPA provider showing multitenancy in action. In short, it adds EclipseLink annotations to a JPA entity and deploys two identical applications with different tenant-id properties defined in the persistence.xml descriptor. Each application only sees its own data, yet everything is stored in the same table which was augmented with a discriminator column. For more advanced uses such as tenant property being set on the @PersistenceContext, XML configuration of multitenant JPA entities, and more check out the nicely written wiki page.

  • Did you miss the IIS7 FastCGI Update ?

    In case you did, there are some interesting improvements like. Monitor changes to a file. The module can be configured to listen for file change notifications on a specific file and when that file changes, the module will recycle FastCGI processes for the process pool. This feature can be used to recycle PHP processes when changes to php.ini file occur. To enable this feature use the monitorChangesTo setting in the <fastCgi> configuration element. Real-time tuning of MaxInstances setting....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Some New .NET Toys (Repost)

    - by Kevin Grossnicklaus
    Last week I was fortunate enough to spend time in Redmond on Microsoft’s campus for the 2011 Microsoft MVP Summit. It was great to hang out with a number of old friends and get the opportunity to talk tech with the various product teams up at Microsoft. The weather wasn’t exactly sunny but Microsoft always does a great job with the Summit and everyone had a blast (heck, I even got to run the bases at SafeCo field) While much of what we saw is covered under NDA, there a ton of great things in the pipeline from Microsoft and many things that are already available (or just became so) that I wasn’t necessarily aware of. The purpose of this post is to share some of the info I learned on resources and tools available to .NET developers today. Please let me know if you have any questions (or if you know of something else cool which might benefit others). Enjoy! Visual Studio 2010 SP1 Microsoft has issued the RTM release of Visual Studio 2010 SP1. You can download the full SP1 on MSDN as of today (March 10th to the general public) and take advantage of such things as: Silverlight 4 is included in the box (as opposed to a separate install) Silverlight 4 Profiling WCF RIA Services SP1 Intellitrace for 64-bit and SharePoint ASP.NET now easily supports IIS Express and SQL CE Want a description of all that’s new beyond the above biased list (which arguably only contains items I think are important)? Check out this KB article. Portable Library Tools CTP Without much fanfare Microsoft has released a CTP of a new add-in to Visual Studio 2010 which simplifies code sharing between projects targeting different runtimes (i.e. Silverlight, WPF, Win7 Phone, XBox). With this Add-In installed you can add a new project of type “Portable Library” and specify which platforms you wish to target. Once that is done, any code added to this library will be limited to use only features which are common to all selected frameworks. Other projects can now reference this portable library and be provided assemblies custom built to their environment. This greatly simplifies the current process of sharing linked files between platforms like WPF and Silverlight. You can find out more about this CTP and how it works on this great blog post. Visual Studio Async CTP Microsoft has also released a CTP of a set of language and framework enhancements to provide a much more powerful asynchronous programming model. Due to the focus on async programming in all types of platforms (and it being the ONLY option in Silverlight and Win7 phone) a move towards a simpler and more understandable model is always a good thing. This CTP (called Visual Studio Async CTP) can be downloaded here. You can read more about this CTP on this blog post. MSDN Code Samples Gallery Microsoft has also launched new code samples gallery on their MSDN site: http://code.msdn.microsoft.com/. This site allows you to easily search for small samples of code related to a particular technology or platform. If a sample of code you are looking for is not found, you can request one via the site and other developers can see your request and provide a sample to the site to suit your needs. You can also peruse requested samples and, if you find a scenario where you can provide value, upload your own sample for the benefit of others. Samples are packaged into the VS .vsix format and include any necessary references/dependencies. By using .vsix as the deployment mechanism, as samples are installed from the site they are kept in your Visual Studio 2010 Samples Gallery and kept for your future reference. If you get a chance, check out the site and see how it is done. Although a somewhat simple concept, I was very impressed with their implementation and the way they went about trying to suit a need. I’ll definitely be looking there in the future as need something or want to share something. MSDN Search Capabilities Another item I learned recently and was not aware of (that might seem trivial to some) is the power of the MSDN site’s search capabilities. Between the Code Samples Gallery described above and the search enhancements on MSDN, Microsoft is definitely investing in their platform to help provide developers of all skill levels the tools and resources they need to be successful. What do I mean by the MSDN search capability and why should you care? If you go to the MSDN home page (http://msdn.microsoft.com) and use the “Search MSDN with Big” box at the very top of the page you will see some very interesting results. First, the search actually doesn’t just search the MSDN library it searches: MSDN Library All Microsoft Blogs CodePlex StackOverflow Downloads MSDN Magazine Support Knowledgebase (I’m not sure it even ends there but the above are all I know of) Beyond just searching all the above locations, the results are formatted very nicely to give some contextual information based on where the result came from. For example, if a keyword search returned results from CodePlex, each row in the search results screen would include a large amount of information specific to CodePlex such as: Looking at the above results immediately tells you everything from the page views to the CodePlex ratings. All in all, knowing that this much information is indexed and available from a single search location will lead me to utilize this as one of my initial searches for development information.

  • Silverlight 5 &ndash; What&rsquo;s New? (Including Screenshots &amp; Code Snippets)

    - by mbcrump
    Silverlight 5 is coming next year (2011) and this blog post will tell you what you need to know before the beta ships. First, let me address people saying that it is dead after PDC 2010. I believe that it’s best to see what the market is doing, not the vendor. Below is a list of companies that are developing Silverlight 4 applications shown during the Silverlight Firestarter. Some of the companies have shipped and some haven’t. It’s just great to see the actual company names that are working on Silverlight instead of “people are developing for Silverlight”. The next thing that I wanted to point out was that HTML5, WPF and Silverlight can co-exist. In case you missed Scott Gutherie’s keynote, they actually had a slide with all three stacked together. This shows Microsoft will be heavily investing in each technology.  Even I, a Silverlight developer, am reading Pro HTML5. Microsoft said that according to the Silverlight Feature Voting site, 21k votes were entered. Microsoft has implemented about 70% of these votes in Silverlight 5. That is an amazing number, and I am crossing my fingers that Microsoft bundles Silverlight with Windows 8. Let’s get started… what’s new in Silverlight 5? I am going to show you some great application and actual code shown during the Firestarter event. Media Hardware Video Decode – Instead of using CPU to decode, we will offload it to GPU. This will allow netbooks, etc to play videos. Trickplay – Variable Speed Playback – Pitch Correction (If you speed up someone talking they won’t sound like a chipmunk). Power Management – Less battery when playing video. Screensavers will no longer kick in if watching a video. If you pause a video then screensaver will kick in. Remote Control Support – This will allow users to control playback functions like Pause, Rewind and Fastforward. IIS Media Services 4 has shipped and now supports Azure. Data Binding Layout Transitions – Just with a few lines of XAML you can create a really rich experience that is not using Storyboards or animations. RelativeSource FindAncestor – Ancestor RelativeSource bindings make it much easier for a DataTemplate to bind to a property on a container control. Custom Markup Extensions – Markup extensions allow code to be run at XAML parse time for both properties and event handlers. This is great for MVVM support. Changing Styles during Runtime By Binding in Style Setters – Changing Styles at runtime used to be a real pain in Silverlight 4, now it’s much easier. Binding in style setters allows bindings to reference other properties. XAML Debugging – Below you can see that we set a breakpoint in XAML. This shows us exactly what is going on with our binding.  WCF & RIA Services WS-Trust Support – Taken from Wikipedia: WS-Trust is a WS-* specification and OASIS standard that provides extensions to WS-Security, specifically dealing with the issuing, renewing, and validating of security tokens, as well as with ways to establish, assess the presence of, and broker trust relationships between participants in a secure message exchange. You can reduce network latency by using a background thread for networking. Supports Azure now.  Text and Printing Improved text clarity that enables better text rendering. Multi-column text flow, Character tracking and leading support, and full OpenType font support.  Includes a new Postscript Vector Printing API that provides control over what you print . Pivot functionality baked into Silverlight 5 SDK. Graphics Immediate mode graphics support that will enable you to use the GPU and 3D graphics supports. Take a look at what was shown in the demos below. 1) 3D view of the Earth – not really a real-world application though. A doctor’s portal. This demo really stood out for me as it shows what we can do with the 3D / GPU support. Out of Browser OOB applications can now create and manage childwindows as shown in the screenshot below.  Trusted OOB applications can use P/Invoke to call Win32 APIs and unmanaged libraries.  Enterprise Group Policy Support allow enterprises to lock down or up the sandbox capabilities of Silverlight 5 applications. In this demo, he tore the “notes” off of the application and it appeared in a new window. See the black arrow below. In this demo, he connected a USB Device which fired off a local Win32 application that provided the data off the USB stick to Silverlight. Another demo of a Silverlight 5 application exporting data right into Excel running inside of browser. Testing They demoed Coded UI, which is available now in the Visual Studio Feature Pack 2. This will allow you to create automated testing without writing any code manually. Performance: Microsoft has worked to improve the Silverlight startup time. Silverlight 5 provides 64-bit browser support.  Silverlight 5 also provides IE9 Hardware acceleration.   I am looking forward to Silverlight 5 and I hope you are too. Thanks for reading and I hope you visit again soon.  Subscribe to my feed CodeProject

  • B2B and B2C alike… but a little different – Oracle Commerce named Leader in Forrester B2B Commerce Wave

    - by Katrina Gosek
    We weren’t surprised to see Oracle Commerce positioned as a Leader in Forrester Research, Inc.’s first Commerce Wave focused on B2B, “The Forrester Wave™: B2B Commerce Suites, Q4 2013,” released earlier this month. We believe that the report validates much of what we’ve heard from our largest customers – the world’s largest distribution, manufacturing and high-tech customers who sell billions of dollars of goods and services to other businesses through their Web channels. More importantly, we feel that the report confirms something very important: B2B and B2C Commerce are alike… but a little different. B2B and B2C Commerce are alike… Clearly, B2C experiences have set expectations for B2B. Every B2B buyer is a consumer at home and brings the same expectations to a website selling electronic components, aftermarket parts, or MRO products. Forrester calls these rich consumer-based capabilities that help B2B customers do their jobs “table stakes”: front-office content, community, and commerce features that meet customer expectations for 24x7x365 ordering, real-time customer service, and expedited shipping — both online and on mobile devices: “Whether they are just beginning to sell online or are in the late stages of launching a next-generation site, B2B eCommerce operations today must: offer a customer experience standard comparable to what leading b2c sites now offer; address the growing influence that mobile devices are having in the workplace; make a qualitative and quantitative business case that drives sustained investment.” Just five years ago, many of our B2B customers’ online business comprised only 5-10% of their total revenue. Today, when we speak to those same brands, we hear about double and triple digit growth in their online channels. Many have seen the percentage of the business they perform in their web channels cross the 30-50% threshold. You can hear first-hand from several Oracle Commerce B2B customers about the success they are seeing, and what they’re trying to accomplish (Carolina Biological, Premier Farnell, DeliXL, Elsevier). It seems that this market momentum is likely the reason Forrester broke out the separate B2B Commerce Wave from the B2C Wave. In fact, B2B is becoming the larger force in commerce, expected to collect twice the online dollars of B2C this year ($559 billion). But a little different… Despite the similarities, there is a key and very important difference between B2C and B2B. Unlike a consumer shopping for shoes, a business shopper buying from a distributor or manufacturer is coming to the Web channel as a part of their job. So in addition to a rich, consumer-like experience this shopper expects, these B2B buyers need quoting tools and complex pricing capabilities, like eProcurement, bulk order entry, and other self-service tools such as account, contract and organization management. Forrester also is emphasizing three additional “back-end” tools and capabilities their clients say they need to drive growth in their B2B online channels: i) product information management (PIM), which provides a single system of record for large part lists and product catalogs; ii) web content management (WCM), needed to manage large volumes of unstructured marketing information, and iii) order management systems (OMS), which manage and orchestrate the complex B2B order life cycle from quote through approval, submission to manufacturing, distribution and delivery. We would like to expand on each of these 3 areas: As Forrester suggests, back-end PIM is definitely needed by B2B Commerce providers. Most B2B companies have made significant investments in enterprise-grade PIMs, given the importance of product data management for aggregation and syndication of content, product attribution, analytics, and handling of complex workflows. While in principle it may sound appealing to have a PIM as part of a commerce offering (especially for SMBs who have to do more with less), our customers have typically found that PIM in a commerce platform is largely redundant with what they already have in-place, and is not fully-featured or robust enough to handle the complexity of the product data sets that B2B distributors and manufacturers usually handle. To meet the PIM needs for commerce, Oracle offers enterprise PIM (Product Hub/Fusion PIM) and a robust enterprise data quality product (EDQP) integrated with the Oracle Commerce solution. These are key differentiators of our offering and these capabilities are becoming even more tightly integrated with Oracle Commerce over time. For Commerce, what customers really need is a robust product catalog and content management system for enabling business users to further enrich and ready catalog and content data to be presented and sold online.  This has been a significant area of investment in the Oracle Commerce platform , which continue to get stronger. We see this combination of capabilities as best meeting the needs of our customers for a commerce platform without adding a largely redundant, less functional PIM in the commerce front-end.  On the topic of web content management, we were pleased to see Forrester cite Oracle’s differentiated digital experience capability in this area and the “unique opportunity in the market to lead the convergence of commerce and content management with the amalgamation of Oracle Commerce with WebCenter Sites (formally FatWire).” Strong content management capabilities are critical for distributors and manufacturers who are frequently serving an engineering audience coming to their websites to conduct product research in search of technical data sheets, drawings, videos and more. The convergence of content, commerce, and experience is critical for B2B brands selling online. Regarding order management, Forrester notes that many businesses use their existing back-end enterprise resource planning (ERP) systems to manage order life cycles.  We hear the same from most of our B2B customers, as they already have an ERP system—if not several of them—and are not interested in yet another one. So what do we take away from the Wave results? Forrester notes that the Oracle Commerce Platform “has always had strong B2B commerce capabilities and Oracle certainly has an exhaustive list of B2B customers using the solution.”  What makes us excited about developing leading B2B solutions are the close relationships with our customers and the clear opportunity in the market – which we'll address in an exciting new release planned for the next 12 months. Oracle has one of the world’s largest B2B customer bases, providing leading solutions across key business-to-business functions – from marketing, sales automation, and service to master data management, and ERP.

Raymond James is a diversified financial services company, which provides financial planning, wealth management, investment banking, and asset management. They are using Oracle GoldenGate and Oracle Data Integrator to feed their operational data store (ODS), which supports application services across the enterprise. A major requirement for their project was low data latency, as key decisions are made based on the data in the ODS. They were able to fulfill this requirement due to the Oracle Data Integrator’s integrated solution with Oracle GoldenGate. Oracle GoldenGate captures changed data from different systems including Oracle Database, HP NonStop and Microsoft SQL Server into a single data store on SQL Server 2008. Oracle Data Integrator provides data transformations for the ODS. Leveraging ODI’s integration with GoldenGate, Raymond James now sees a 9 second median latency (from source commit to ODS target commit). The ODS solution delivers high quality, accurate data for consuming applications such as Raymond James’ next generation client and portfolio management systems as well as real-time operational reporting. It enables timely information for making better decisions. There are more benefits Raymond James achieved with this implementation of Oracle’s data integration solution. The software developers and architects of this solution, Tim Garrod and Ryan Fonnett, have told us during their presentation at OpenWorld that they also reduced application complexity significantly while improving developer productivity through trusted operational services. They were able to utilize CDC to generate alerts for business users, and for applications (for example for cache hydration mechanisms). One cool innovation example among many in this project is that using ODI's flexible architecture, Tim and Ryan could build 24/7 self-healing processes. And these processes have hardly failed. Integration processes fixes the errors itself. Pretty amazing; and a great solution for environments that need such reliability and availability. (You can see Tim and Ryan’s photo with the Innovation Award above.) The other winner of this year in the data integration category, Morrison Supermarkets, is the UK’s 4th largest grocery retailer. The company has been migrating all their legacy applications on to a new-world application set based on Oracle and consolidating all BI on to a single Oracle platform. The company recently implemented Oracle Exadata as the data warehouse engine and uses Oracle Business Intelligence EE. Their goal with deploying GoldenGate and ODI was to provide BI data to the enterprise in a way that it also supports operational decision making requirements from a wide range of Oracle based ERP applications such as E-Business Suite, PeopleSoft, Oracle Retail Suite. They use GoldenGate’s log-based change data capture capabilities and Oracle Data Integrator to populate the Oracle Retail Data Model. The electronic point of sale (EPOS) integration solution they built processes over 80 million transactions/day at busy periods in near real time (15 mins). It provides valuable insight to Retail and Commercial teams for both intra-day and historical trend analysis. As I mentioned in yesterday’s blog, the right data integration platform can transform the business. Here is another example: The point-of-sale integration enabled the grocery chain to optimize its stock management, leading to another award: Morrisons won the Grocer 33 award in 2012 - beating all other major UK supermarkets in product availability. Congratulations, Morrisons,on another award! Celebrating the innovation and the success of our customers with Oracle’s data integration products was definitely a highlight of Oracle OpenWorld for me. I look forward to hearing more from Raymond James, Morrisons, and the other customers that presented their data integration projects at OpenWorld, on how they are creating more value for their organizations.

  • Why hill climbing is called anytime algorithm?

    - by crucified soul
    From wikipedia, Anytime algorithm In computer science an anytime algorithm is an algorithm that can return a valid solution to a problem even if it's interrupted at any time before it ends. The algorithm is expected to find better and better solutions the more time it keeps running. Hill climbing Hill climbing can often produce a better result than other algorithms when the amount of time available to perform a search is limited, such as with real-time systems. It is an anytime algorithm: it can return a valid solution even if it's interrupted at any time before it ends. Hill climbing algorithm can stuck into local optima or ridge, after that even if it runs infinite time, the result won't be any better. Then, why hill climbing is called anytime algorithm?

  • how do you document your development process?

    - by David
    My current state is a mixture of spreadsheets, wikis, documents, and dated folders for my input/configuration and output files and bzr version control for code. I am relatively new to programming that requires this level of documentation, and I would like to find a better, more coherent approach. update (for clarity): My inputs are data used to generate configuration files with parameter values and my outputs are analyses of model predictions. I would really like to have an approach that allows me to associate particular configuration(s) with particular outputs, so that I can ask questions of my documentation such as "what causes over/under estimates?" or "what causes error 'X'"?

  • Apress Books - 4 - Introducing Visual C# 2010 - Initial comments

    - by TATWORTH
    Apress books Visual C# 2010 (ISBN 978-1-4302-3171-4) - http://www.apress.com/book/view/1430231718 is both an excellent introduction to C# programming and a manual for those with experiance. So far I have only been through a few chapters but I have been favourably impressed. In the chapter on Exceptions, I have posted an errata regarding the custom exception in  listing 14-17; it is missing an overload required by FXCOP     private CustomException(SerializationInfo info, StreamingContext context) : base(info, context)     {     } Aside of this minor point, I have no hesitation to recommending this book to anyone who wishes to learn C#.

  • SQL Server Master class winner

    - by Testas
     The winner of the SQL Server MasterClass competition courtesy of the UK SQL Server User Group and SQL Server Magazine!    Steve Hindmarsh     There is still time to register for the seminar yourself at:  www.regonline.co.uk/kimtrippsql     More information about the seminar     Where: Radisson Edwardian Heathrow Hotel, London  When: Thursday 17th June 2010  This one-day MasterClass will focus on many of the top issues companies face when implementing and maintaining a SQL Server-based solution. In the case where a company has no dedicated DBA, IT managers sometimes struggle to keep the data tier performing well and the data available. This can be especially troublesome when the development team is unfamiliar with the affect application design choices have on database performance. The Microsoft SQL Server MasterClass 2010 is presented by Paul S. Randal and Kimberly L. Tripp, two of the most experienced and respected people in the SQL Server world. Together they have over 30 years combined experience working with SQL Server in the field, and on the SQL Server product team itself. This is a unique opportunity to hear them present at a UK event which will: Debunk many of the ingrained misconceptions around SQL Server's behaviour    Show you disaster recovery techniques critical to preserving your company's life-blood - the data    Explain how a common application design pattern can wreak havoc in the database Walk through the top-10 points to follow around operations and maintenance for a well-performing and available data tier! Please Note: Agenda may be subject to change  Sessions Abstracts  KEYNOTE: Bridging the Gap Between Development and Production    Applications are commonly developed with little regard for how design choices will affect performance in production. This is often because developers don't realize the implications of their design on how SQL Server will be able to handle a high workload (e.g. blocking, fragmentation) and/or because there's no full-time trained DBA that can recognize production problems and help educate developers. The keynote sets the stage for the rest of the day. Discussing some of the issues that can arise, explaining how some can be avoided and highlighting some of the features in SQL 2008 that can help developers and DBAs make better use of SQL Server, and troubleshoot when things go wrong.   SESSION ONE: SQL Server Mythbusters  It's amazing how many myths and misconceptions have sprung up and persisted over the years about SQL Server - after many years helping people out on forums, newsgroups, and customer engagements, Paul and Kimberly have heard it all. Are there really non-logged operations? Can interrupting shrinks or rebuilds cause corruption? Can you override the server's MAXDOP setting? Will the server always do a table-scan to get a row count? Many myths lead to poor design choices and inappropriate maintenance practices so these are just a few of many, many myths that Paul and Kimberly will debunk in this fast-paced session on how SQL Server operates and should be managed and maintained.   SESSION TWO: Database Recovery Techniques Demo-Fest  Even if a company has a disaster recovery strategy in place, they need to practice to make sure that the plan will work when a disaster does strike. In this fast-paced demo session Paul and Kimberly will repeatedly do nasty things to databases and then show how they are recovered - demonstrating many techniques that can be used in production for disaster recovery. Not for the faint-hearted!   SESSION THREE: GUIDs: Use, Abuse, and How To Move Forward   Since the addition of the GUID (Microsoft’s implementation of the UUID), my life as a consultant and "tuner" has been busy. I’ve seen databases designed with GUID keys run fairly well with small workloads but completely fall over and fail because they just cannot scale. And, I know why GUIDs are chosen - it simplifies the handling of parent/child rows in your batches so you can reduce round-trips or avoid dealing with identity values. And, yes, sometimes it's even for distributed databases and/or security that GUIDs are chosen. I'm not entirely against ever using a GUID but overusing and abusing GUIDs just has to be stopped! Please, please, please let me give you better solutions and explanations on how to deal with your parent/child rows, round-trips and clustering keys!   SESSION 4: Essential Database Maintenance  In this session, Paul and Kimberly will run you through their top-ten database maintenance recommendations, with a lot of tips and tricks along the way. These are distilled from almost 30 years combined experience working with SQL Server customers and are geared towards making your databases more performant, more available, and more easily managed (to save you time!). Everything in this session will be practical and applicable to a wide variety of databases. Topics covered include: backups, shrinks, fragmentation, statistics, and much more! Focus will be on 2005 but we'll explain some of the key differences for 2000 and 2008 as well. Speaker Biographies     Kimberley L. Tripp Paul and Kimberly are a husband-and-wife team who own and run SQLskills.com, a world-renowned SQL Server consulting and training company. They are both SQL Server MVPs and Microsoft Regional Directors, with over 30 years of combined experience on SQL Server. Paul worked on the SQL Server team for nine years in development and management roles, writing many of the DBCC commands, and ultimately with responsibility for core Storage Engine for SQL Server 2008. Paul writes extensively on his blog (SQLskills.com/blogs/Paul) and for TechNet Magazine, for which he is also a Contributing Editor. Kimberly worked on the SQL Server team in the early 1990s as a tester and writer before leaving to found SQLskills and embrace her passion for teaching and consulting. Kimberly has been a staple at worldwide conferences since she first presented at TechEd in 1996, and she blogs at SQLskills.com/blogs/Kimberly. They have written Microsoft whitepapers and books for SQL Server 2000, 2005 and 2008, and are regular, top-rated presenters worldwide on database maintenance, high availability, disaster recovery, performance tuning, and SQL Server internals. Together they teach the SQL MCM certification and throughout Microsoft.In their spare time, they like to find frogfish in remote corners of the world.   Speaker Testimonials  "To call them good trainers is an epic understatement. They know how to deliver technical material in ways that illustrate it well. I had to stop Paul at one point and ask him how long it took to build a particular slide because the animations were so good at conveying a hard-to-describe process." "These are not beginner presenters, and they put an extreme amount of preparation and attention to detail into everything that they do. Completely, utterly professional." "When it comes to the instructors themselves, Kimberly and Paul simply have no equal. Not only are they both ultimate authorities, but they have endless enthusiasm about the material, and spot on delivery. If either ever got tired they never showed it, even after going all day and all week. We witnessed countless demos over the course of the week, some extremely involved, multi-step processes, and I can’t recall one that didn’t go the way it was supposed to." "You might think that with this extreme level of skill comes extreme levels of egotism and lack of patience. Nothing could be further from the truth. ... They simply know how to teach, and are approachable, humble, and patient." "The experience Paul and Kimberly have had with real live customers yields a lot more information and things to watch out for than you'd ever get from documentation alone." “Kimberly, I just wanted to send you an email to let you know how awesome you are! I have applied some of your indexing strategies to our website’s homegrown CMS and we are experiencing a significant performance increase. WOW....amazing tips delivered in an exciting way!  Thanks again”

  • html/css vs CMS

    - by Matt
    I am currently a CS student and an aspiring programmer/web developer. I am wondering whether it is worth taking the time to master html and css to make websites when these CMS services/wysiwyg editors (wordpress, squarespace) seem to be becoming more and more functional. Does anyone think these publishing services might eventually make the need to design websites from raw code unnecessary? If not, please explain why. If designing a website eventually becomes as simple as using Photoshop I would much rather invest my time in programming languages.

  • In general, are programmers or artists paid better?

    - by jokoon
    I'm in a private game programming school where there also are 3D art classes; sadly, there seems to be a lot more students in those latter classes, something like 50% or 100% more. So I was wondering: in the real video game industry, which of the artist/modeler or the programmer is more likely to be wanted in a company, so who will be paid more ? I'm sure there are artists which are obviously paid better than other programmers and I'm sure there are other sorts of jobs in the game industry (sound, management, testers), but I wanted to know if there is a general tendency for one or the other. And sometime I wonder even if an artist can happen to write scripts...

  • Ctrl + C doesn't abort programs in terminal

    - by jake
    I changed the keyboard shortcut in terminal so that Ctrl + C would copy text. I realized I can't abort a program I am running since Ctrl + C used to be the abort command. I know that Ctrl + Shift + C works but want it switched back. Is there a way to revert the keyboard shortcuts to the real defaults before I decided to mess with it? What is the abort command defined as in keyboard shortcuts? Not a big program if I can't but it would be nice to know.
