  • SharePoint 2010 Workflow for Multiple Items (Architecture)

    - by erobillard
    I had the question today of whether SharePoint 2010 supports workflow on multiple items, since Groove's workflow apparently supported multiple items and that model disappeared when Groove Workspaces were amalgamated into SharePoint Sites and SharePoint Workspace (the client utility). It's a great question, the short answer is that yes, it's possible. You could brute-force it in 2007 and that strategy should still carry over to 2010, and 3 new features (that I can think of) support multi-item scenarios...(read more)

  • Rule of thumb for enemy art design in 2D platformer

    - by Terrance
    I'm at the early stages of developing a 2D side scrolling open ended platformer (think Metroidvania) and am having a bit of difficulty at enemy design inspiration for something of a scifi, nature, fantasy setting that isn't overly familar or obvious. I haven't seen too many articles, blogs or books that talk about the subject at great length. Is there a fair rule of thumb when coming up with enemy art with respect to keeping your player engaged?

  • Book Review (Book 11) - Applied Architecture Patterns on the Microsoft Platform

    - by BuckWoody
    This is a continuation of the books I challenged myself to read to help my career - one a month, for year. You can read my first book review here, and the entire list is here. The book I chose for April 2012 was: Applied Architecture Patterns on the Microsoft Platform. I was traveling at the end of last month so I’m a bit late posting this review here. Why I chose this book: I actually know a few of the authors on this book, so when they told me about it I wanted to check it out. The premise of the book is exactly as it states in the title - to learn how to solve a problem using products from Microsoft. What I learned: I liked the book - a lot. They've arranged the content in a "Solution Decision Framework", that presents a few elements to help you identify a need and then propose alternate solutions to solve them, and then the rationale for the choice. But the payoff is that the authors then walk through the solution they implement and what they ran into doing it. I really liked this approach. It's not a huge book, but one I've referred to again since I've read it. It's fairly comprehensive, and includes server-oriented products, not things like Microsoft Office or other client-side tools. In fact, I would LOVE to have a work like this for Open Source and other vendors as well - would make for a great library for a Systems Architect. This one is unashamedly aimed at the Microsoft products, and even if I didn't work here, I'd be fine with that. As I said, it would be interesting to see some books on other platforms like this, but I haven't run across something that presents other systems in quite this way. And that brings up an interesting point - This book is aimed at folks who create solutions within an organization. It's not aimed at Administrators, DBA's, Developers or the like, although I think all of those audiences could benefit from reading it. The solutions are made up, and not to a huge level of depth - nor should they be. It's a great exercise in thinking these kinds of things through in a structured way. The information is a bit dated, especially for Windows and SQL Azure. While the general concepts hold, the cloud platform from Microsoft is evolving so quickly that any printed book finds it hard to keep up with the improvements. I do have one quibble with the text - the chapters are a bit uneven. This is always a danger with multiple authors, but it shows up in a couple of chapters. I winced at one of the chapters that tried to take a more conversational, humorous style. This kind of academic work doesn't lend itself to that style. I recommend you get the book - and use it. I hope they keep it updated - I'll be a frequent customer. :)

  • SQLAuthority News – Presented Soft Skill Session on Presentation Skills at SQL Bangalore on May 3, 2014

    - by Pinal Dave
    I have presented on various database technologies for almost 10 years now. SQL, Database and NoSQL have been part of my life. Earlier this month, I had the opportunity to present on the topic Performing an Effective Presentation. I must say it was blast to prepare as well as present this session. This event was part of the SQL Bangalore community. If you are in Bangalore, you must be part of this group. SQL Bangalore is a wonderful community and we always have a great response when we present on technology. It is SQL User Group and we discuss everything SQL there. This month we had SQL Server 2014 theme and we had a community launch of SQL Server. We have the best of the best speakers presenting on SQL Server 2014 technology. The event had amazing speakers and each of them did justice to the subject. You can read about this over here. In this session I told a story from my life. I talked about who inspired me and how I learned to speak in public. I told stories about two legends  who have inspired me. There is no video recording of this session. If you want to get resources from this session, please sign up my newsletter at http://bit.ly/sqllearn. Well, I had a great time at this event. We had over 250 people showed up at this event and had a grand  time together. I personally enjoyed a session of Amit Benerjee, Balmukund Lakhani and Vinod Kumar. Ken and Surabh also entertained the audience. Overall, this was a grand event and if you were in Bangalore and did not make it to this event. You did miss out on a few things. Here are a few photos of this event.

  • Change CSS EMs to Percentage Automatically.

    - by Zachary Brown
    I cheated on a small site I was working on and used a site builder (Web Dwarf by Virtual Mechanics) to save time. I didn't realize it at the time, but this builder specifies the width, height and positions using CSS EMs. Is there an automated tool out there that will read through the CSS and convert each EM to a percentage so it will display correctly on wide screens as well? Any help would be great! Thanks. Here is the CSS: http://pastebin.de/14055

  • Time to Check Your Servers

    - by fatherjack
    Do you know how to find the time that your SQL Server started? Since SQL Server 2008 you can use: SELECT sqlserver_start_timeFROM sys.dm_os_sys_info On one of my servers this gives me: This is great, and can be used in lots of ways. I happened across the [sys].[dm_exec_requests]view the other day and out of curiosity ran the query SELECT MIN(start_time) AS [start time]FROM [sys].[dm_exec_requests] AS der And I was surprised to see the result as: Almost exactly an hour different. Now as...(read more)

  • Top 10 CV Tips - update

    - by simonsabin
    Three years ago I wrote a blog post about my top 10 CV tips. http://sqlblogcasts.com/blogs/simons/archive/2007/01/09/TOP-10-CV-Tips.aspx The world has changed slightly since then and one item I would add is that if you are active on the forums, stack overflow etc then put a link to your profile. This is a great way for recruiters to see some of your knowledge and importantly how you respond and interact with people. The latter is something that is crucial when employing someone but is very difficult...(read more)

  • S#arp Architecture 1.5.1 released

    - by AlecWhittington
    So far we have had some great success with the 1.5 release of S#arp Architecture, but there were a few issues that made it into the release that needed to be corrected. These issues were: Unnecessary assemblies in the root /bin and SolutionItemsContainer folders Nant folder removed from root /bin - this was causing issues with the build scripts that come with the project if the user did not have Nant installed and available via a path variable VS 2010 template - the CrudScaffoldingForEnterpriseApp...(read more)

  • The SPARC SuperCluster

    - by Karoly Vegh
    Oracle has been providing a lead in the Engineered Systems business for quite a while now, in accordance with the motto "Hardware and Software Engineered to Work Together." Indeed it is hard to find a better definition of these systems.  Allow me to summarize the idea. It is:  Build a compute platform optimized to run your technologies Develop application aware, intelligently caching storage components Take an impressively fast network technology interconnecting it with the compute nodes Tune the application to scale with the nodes to yet unseen performance Reduce the amount of data moving via compression Provide this all in a pre-integrated single product with a single-pane management interface All these ideas have been around in IT for quite some time now. The real Oracle advantage is adding the last one to put these all together. Oracle has built quite a portfolio of Engineered Systems, to run its technologies - and run those like they never ran before. In this post I'll focus on one of them that serves as a consolidation demigod, a multi-purpose engineered system.  As you probably have guessed, I am talking about the SPARC SuperCluster. It has many great features inherited from its predecessors, and it adds several new ones. Allow me to pick out and elaborate about some of the most interesting ones from a technological point of view.  I. It is the SPARC SuperCluster T4-4. That is, as compute nodes, it includes SPARC T4-4 servers that we learned to appreciate and respect for their features: The SPARC T4 CPUs: Each CPU has 8 cores, each core runs 8 threads. The SPARC T4-4 servers have 4 sockets. That is, a single compute node can in parallel, simultaneously  execute 256 threads. Now, a full-rack SPARC SuperCluster has 4 of these servers on board. Remember the keyword demigod.  While retaining the forerunner SPARC T3's exceptional throughput, the SPARC T4 CPUs raise the bar with single performance too - a humble 5x better one than their ancestors.  actually, the SPARC T4 CPU cores run in both single-threaded and multi-threaded mode, and switch between these two on-the-fly, fulfilling not only single-threaded OR multi-threaded applications' needs, but even mixed requirements (like in database workloads!). Data security, anyone? Every SPARC T4 CPU core has a built-in encryption engine, that is, encryption algorithms cast into silicon.  A PCI controller right on the chip for customers who need I/O performance.  Built-in, no-cost Virtualization:  Oracle VM for SPARC (the former LDoms or Logical Domains) is not a server-emulation virtualization technology but rather a serverpartitioning one, the hypervisor runs in the server firmware, and all the VMs' HW resources (I/O, CPU, memory) are accessed natively, without performance overhead.  This enables customers to run a number of Solaris 10 and Solaris 11 VMs separated, independent of each other within a physical server II. For Database performance, it includes Exadata Storage Cells - one of the main reasons why the Exadata Database Machine performs at diabolic speed. What makes them important? They provide DB backend storage for your Oracle Databases to run on the SPARC SuperCluster, that is what they are built and tuned for DB performance.  These storage cells are SQL-aware.  That is, if a SPARC T4 database compute node executes a query, it doesn't simply request tons of raw datablocks from the storage, filters the received data, and throws away most of it where the statement doesn't apply, but provides the SQL query to the storage node too. The storage cell software speaks SQL, that is, it is able to prefilter and through that transfer only the relevant data. With this, the traffic between database nodes and storage cells is reduced immensely. Less I/O is a good thing - as they say, all the CPUs of the world do one thing just as fast as any other - and that is waiting for I/O.  They don't only pre-filter, but also provide data preprocessing features - e.g. if a DB-node requests an aggregate of data, they can calculate it, and handover only the results, not the whole set. Again, less data to transfer.  They support the magical HCC, (Hybrid Columnar Compression). That is, data can be stored in a precompressed form on the storage. Less data to transfer.  Of course one can't simply rely on disks for performance, there is Flash Storage included there for caching.  III. The low latency, high-speed backbone network: InfiniBand, that interconnects all the members with: Real High Speed: 40 Gbit/s. Full Duplex, of course. Oh, and a really low latency.  RDMA. Remote Direct Memory Access. This technology allows the DB nodes to do exactly that. Remotely, directly placing SQL commands into the Memory of the storage cells. Dodging all the network-stack bottlenecks, avoiding overhead, placing requests directly into the process queue.  You can also run IP over InfiniBand if you please - that's the way the compute nodes can communicate with each other.  IV. Including a general-purpose storage too: the ZFSSA, which is a unified storage, providing NAS and SAN access too, with the following features:  NFS over RDMA over InfiniBand. Nothing is faster network-filesystem-wise.  All the ZFS features onboard, hybrid storage pools, compression, deduplication, snapshot, replication, NFS and CIFS shares Storageheads in a HA-Cluster configuration providing availability of the data  DTrace Live Analytics in a web-based Administration UI Being a general purpose application data storage for your non-database applications running on the SPARC SuperCluster over whichever protocol they prefer, easily replicating, snapshotting, cloning data for them.  There's a lot of great technology included in Oracle's SPARC SuperCluster, we have talked its interior through. As for external scalability: you can start with a half- of full- rack SPARC SuperCluster, and scale out to several racks - that is, stacking not separate full-rack SPARC SuperClusters, but extending always one large instance of the size of several full-racks. Yes, over InfiniBand network. Add racks as you grow.  What technologies shall run on it? SPARC SuperCluster is a general purpose scaleout consolidation/cloud environment. You can run Oracle Databases with RAC scaling, or Oracle Weblogic (end enjoy the SPARC T4's advantages to run Java). Remember, Oracle technologies have been integrated with the Oracle Engineered Systems - this is the Oracle on Oracle advantage. But you can run other software environments such as SAP if you please too. Run any application that runs on Oracle Solaris 10 or Solaris 11. Separate them in Virtual Machines, or even Oracle Solaris Zones, monitor and manage those from a central UI. Here the key takeaways once again: The SPARC SuperCluster: Is a pre-integrated Engineered System Contains SPARC T4-4 servers with built-in virtualization, cryptography, dynamic threading Contains the Exadata storage cells that intelligently offload the burden of the DB-nodes  Contains a highly available ZFS Storage Appliance, that provides SAN/NAS storage in a unified way Combines all these elements over a high-speed, low-latency backbone network implemented with InfiniBand Can grow from a single half-rack to several full-rack size Supports the consolidation of hundreds of applications To summarize: All these technologies are great by themselves, but the real value is like in every other Oracle Engineered System: Integration. All these technologies are tuned to perform together. Together they are way more than the sum of all - and a careful and actually very time consuming integration process is necessary to orchestrate all these for performance. The SPARC SuperCluster's goal is to enable infrastructure operations and offer a pre-integrated solution that can be architected and delivered in hours instead of months of evaluations and tests. The tedious and most importantly time and resource consuming part of the work - testing and evaluating - has been done.  Now go, provide services.   -- charlie

  • Favorite moments of JavaOne

    - by Tori Wieldt
    There are so many events and sessions to attend at JavaOne, it's unfair to ask people to choose just one thing they liked, but here are some favorite moments: I loved meeting many open source contributors and friends I have not met in person before and seeing that projects like e.g. Hudson are alive and kicking and have a great future ahead of them. -Manfred Moser My "The Problem with Women" session. It had LOADS of interactivity from the audience, who really helped to make that session.  I came out if it with a real sense of optimism - we love our jobs, we love what we do, and we should be proud of telling everyone about it to attract different talent into the industry. (Read her blog JavaOne: The Problem With Women - A Technical Approach for details.) -Trish Gee My kudos to Oracle for making the presentation materials quickly available to the public. Some of them were already available during JavaOne. Lots of slide decks are already there, and in some cases you may even find the video recordings too. Go to http://www.oracle.com/javaone and select JavaOne Technical Sessions.  -Yakov Fain I loved that not only was James Gosling present at the Community Keynote (which felt more like the keynotes of old times [big space, big screens, fun and tech]) but he was also found wandering the halls of the Hilton the day prior. Bring back James! Add back the toys section in the Community Keynote. Let the t-shirt tossing begin anew. These are "small" things that really fire up the community. -Andres Almiray Seeing James Gosling at JavaOne was a real shot in the arm for Java.  He needs to be there every year. -Frank Greco +42 on having James and the T-shirt tossing. -Stephan Janssen The session "Integrate Java with Robots, Home Automation, Musical Instruments, and Kinect." Fabiane Nardon explained connecting Jenkins to jHome to a truck horn placed in their sysadmin's bedroom. She dubbed it "extreme feedback."  -Tori Wieldt The User Group Forum [on Sunday] was a success! Congratulations Bruno Souza and John Yeary and everybody that were involved. I believe it really helps to increase community participation! There were lots of interesting talks, and great discussion with JUG leaders and members. Thank you Oracle for supporting that! -Yara Senger What was your favorite moment? Please comment!
