  • Option Trading: Getting the most out of the event session options

    - by extended_events
    You can control different aspects of how an event session behaves by setting the event session options as part of the CREATE EVENT SESSION DDL. The default settings for the event session options are designed to handle most of the common event collection situations so I generally recommend that you just use the defaults. Like everything in the real world though, there are going to be a handful of “special cases” that require something different. This post focuses on identifying the special cases and the correct use of the options to accommodate those cases. There is a reason it’s called Default The default session options specify a total event buffer size of 4 MB with a 30 second latency. Translating this into human terms; this means that our default behavior is that the system will start processing events from the event buffer when we reach about 1.3 MB of events or after 30 seconds, which ever comes first. Aside: What’s up with the 1.3 MB, I thought you said the buffer was 4 MB?The Extended Events engine takes the total buffer size specified by MAX_MEMORY (4MB by default) and divides it into 3 equally sized buffers. This is done so that a session can be publishing events to one buffer while other buffers are being processed. There are always at least three buffers; how to get more than three is covered later. Using this configuration, the Extended Events engine can “keep up” with most event sessions on standard workloads. Why is this? The fact is that most events are small, really small; on the order of a couple hundred bytes. Even when you start considering events that carry dynamically sized data (eg. binary, text, etc.) or adding actions that collect additional data, the total size of the event is still likely to be pretty small. This means that each buffer can likely hold thousands of events before it has to be processed. When the event buffers are finally processed there is an economy of scale achieved since most targets support bulk processing of the events so they are processed at the buffer level rather than the individual event level. When all this is working together it’s more likely that a full buffer will be processed and put back into the ready queue before the remaining buffers (remember, there are at least three) are full. I know what you’re going to say: “My server is exceptional! My workload is so massive it defies categorization!” OK, maybe you weren’t going to say that exactly, but you were probably thinking it. The point is that there are situations that won’t be covered by the Default, but that’s a good place to start and this post assumes you’ve started there so that you have something to look at in order to determine if you do have a special case that needs different settings. So let’s get to the special cases… What event just fired?! How about now?! Now?! If you believe the commercial adage from Heinz Ketchup (Heinz Slow Good Ketchup ad on You Tube), some things are worth the wait. This is not a belief held by most DBAs, particularly DBAs who are looking for an answer to a troubleshooting question fast. If you’re one of these anxious DBAs, or maybe just a Program Manager doing a demo, then 30 seconds might be longer than you’re comfortable waiting. If you find yourself in this situation then consider changing the MAX_DISPATCH_LATENCY option for your event session. This option will force the event buffers to be processed based on your time schedule. This option only makes sense for the asynchronous targets since those are the ones where we allow events to build up in the event buffer – if you’re using one of the synchronous targets this option isn’t relevant. Avoid forgotten events by increasing your memory Have you ever had one of those days where you keep forgetting things? That can happen in Extended Events too; we call it dropped events. In order to optimizes for server performance and help ensure that the Extended Events doesn’t block the server if to drop events that can’t be published to a buffer because the buffer is full. You can determine if events are being dropped from a session by querying the dm_xe_sessions DMV and looking at the dropped_event_count field. Aside: Should you care if you’re dropping events?Maybe not – think about why you’re collecting data in the first place and whether you’re really going to miss a few dropped events. For example, if you’re collecting query duration stats over thousands of executions of a query it won’t make a huge difference to miss a couple executions. Use your best judgment. If you find that your session is dropping events it means that the event buffer is not large enough to handle the volume of events that are being published. There are two ways to address this problem. First, you could collect fewer events – examine you session to see if you are over collecting. Do you need all the actions you’ve specified? Could you apply a predicate to be more specific about when you fire the event? Assuming the session is defined correctly, the next option is to change the MAX_MEMORY option to a larger number. Picking the right event buffer size might take some trial and error, but a good place to start is with the number of dropped events compared to the number you’ve collected. Aside: There are three different behaviors for dropping events that you specify using the EVENT_RETENTION_MODE option. The default is to allow single event loss and you should stick with this setting since it is the best choice for keeping the impact on server performance low.You’ll be tempted to use the setting to not lose any events (NO_EVENT_LOSS) – resist this urge since it can result in blocking on the server. If you’re worried that you’re losing events you should be increasing your event buffer memory as described in this section. Some events are too big to fail A less common reason for dropping an event is when an event is so large that it can’t fit into the event buffer. Even though most events are going to be small, you might find a condition that occasionally generates a very large event. You can determine if your session is dropping large events by looking at the dm_xe_sessions DMV once again, this time check the largest_event_dropped_size. If this value is larger than the size of your event buffer [remember, the size of your event buffer, by default, is max_memory / 3] then you need a large event buffer. To specify a large event buffer you set the MAX_EVENT_SIZE option to a value large enough to fit the largest event dropped based on data from the DMV. When you set this option the Extended Events engine will create two buffers of this size to accommodate these large events. As an added bonus (no extra charge) the large event buffer will also be used to store normal events in the cases where the normal event buffers are all full and waiting to be processed. (Note: This is just a side-effect, not the intended use. If you’re dropping many normal events then you should increase your normal event buffer size.) Partitioning: moving your events to a sub-division Earlier I alluded to the fact that you can configure your event session to use more than the standard three event buffers – this is called partitioning and is controlled by the MEMORY_PARTITION_MODE option. The result of setting this option is fairly easy to explain, but knowing when to use it is a bit more art than science. First the science… You can configure partitioning in three ways: None, Per NUMA Node & Per CPU. This specifies the location where sets of event buffers are created with fairly obvious implication. There are rules we follow for sub-dividing the total memory (specified by MAX_MEMORY) between all the event buffers that are specific to the mode used: None: 3 buffers (fixed)Node: 3 * number_of_nodesCPU: 2.5 * number_of_cpus Here are some examples of what this means for different Node/CPU counts: Configuration None Node CPU 2 CPUs, 1 Node 3 buffers 3 buffers 5 buffers 6 CPUs, 2 Node 3 buffers 6 buffers 15 buffers 40 CPUs, 5 Nodes 3 buffers 15 buffers 100 buffers   Aside: Buffer size on multi-processor computersAs the number of Nodes or CPUs increases, the size of the event buffer gets smaller because the total memory is sub-divided into more pieces. The defaults will hold up to this for a while since each buffer set is holding events only from the Node or CPU that it is associated with, but at some point the buffers will get too small and you’ll either see events being dropped or you’ll get an error when you create your session because you’re below the minimum buffer size. Increase the MAX_MEMORY setting to an appropriate number for the configuration. The most likely reason to start partitioning is going to be related to performance. If you notice that running an event session is impacting the performance of your server beyond a reasonably expected level [Yes, there is a reasonably expected level of work required to collect events.] then partitioning might be an answer. Before you partition you might want to check a few other things: Is your event retention set to NO_EVENT_LOSS and causing blocking? (I told you not to do this.) Consider changing your event loss mode or increasing memory. Are you over collecting and causing more work than necessary? Consider adding predicates to events or removing unnecessary events and actions from your session. Are you writing the file target to the same slow disk that you use for TempDB and your other high activity databases? <kidding> <not really> It’s always worth considering the end to end picture – if you’re writing events to a file you can be impacted by I/O, network; all the usual stuff. Assuming you’ve ruled out the obvious (and not so obvious) issues, there are performance conditions that will be addressed by partitioning. For example, it’s possible to have a successful event session (eg. no dropped events) but still see a performance impact because you have many CPUs all attempting to write to the same free buffer and having to wait in line to finish their work. This is a case where partitioning would relieve the contention between the different CPUs and likely reduce the performance impact cause by the event session. There is no DMV you can check to find these conditions – sorry – that’s where the art comes in. This is  largely a matter of experimentation. On the bright side you probably won’t need to to worry about this level of detail all that often. The performance impact of Extended Events is significantly lower than what you may be used to with SQL Trace. You will likely only care about the impact if you are trying to set up a long running event session that will be part of your everyday workload – sessions used for short term troubleshooting will likely fall into the “reasonably expected impact” category. Hey buddy – I think you forgot something OK, there are two options I didn’t cover: STARTUP_STATE & TRACK_CAUSALITY. If you want your event sessions to start automatically when the server starts, set the STARTUP_STATE option to ON. (Now there is only one option I didn’t cover.) I’m going to leave causality for another post since it’s not really related to session behavior, it’s more about event analysis. - Mike Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Is there a way to track data structure dependencies from the database, through the tiers, all the way out to a web page?

    - by Sean Mickey
    When we design applications, we generally end up with the same tiered sets of data structures: A persistent data structure that is described using DDL and implemented as RDBMS tables and columns. A set of domain objects that consist primarily of data structures, usually combined with business-rule level logic, that are implemented in a programming language such as Java. A set of service layer interfaces that directly support use case implementations (which use the domain data structures as parameters), implemented as EJBs or something equivalent in another programming language. UI screens that allow users to C reate, R etrieve, U pdate, and (maybe) D elete all manner of data structures and graphs of data structures, with numerous screens and with multiple UI widgets, all structured to support the same data structures. But if you want to change the data structures in any of these tiers, it always seems extremely difficult to assess the impact(s) the change will have across the application. UML can help, but tracing through diagram after diagram is not a real solution to this problem. The best I have ever seen was a homespun data tracking spreadsheet document that listed all of the data structures and walked the relationships from tier-to-tier. Is there a tool or accepted approach that makes it easy to identify a data structure in any tier and easily obtain a list of all dependent: database table and column data structures domain object data structures service layer interface methods and parameter data structures screen & UI component data structures

  • How can I recover data after mistakenly clean-installed 12.04 over 11.10?

    - by T.Kannan
    I recently got a Ubuntu 12.04 LTS i386 DVD Rom and Ubuntu 12.04 LTS alternate cd from the zyxware.com because I don't have a broadband personal connection at home, I am using only the office INTERNET. I have a Dell Inspiron Laptop core 2 duo Processor with 2GB Ram dual boot of Ubuntu 11.10 and Windows Vista. I tried to upgrade My existing fully equipped streamlined Ubuntu 11.10 OS with lot of documents and socialized application packages which have been frequently used by me for the last one year. First I tried to install upgradation from the Ubuntu 12.04 LTS alternate cd while ubuntu 11.10 is on, but every time I got a error message and I couldn't upgrade either thro desktop or through terminal. Then I tried Ubuntu 12.04 LTS i386 DVD the boot option to DVD, I tried to upgrade from existing 11.10 to 12.04 LTS Option, then Upgrading Installation started well and finally got a message Installation completed successfully, Asked for reboot, I rebooted then I have hot a Ubuntu 12.04 LTS Login and I logged on, I have got a big shock that there is everything washed away in the home folders ( all datas, Music collections and vedios etc), all the application installed early in 11.10 were gone nothing left. Now I have got only 12.04 LTS, even It is asking for me to update around 350 mb through net connection. How It was a crazy Ubuntu, It is not a up-gradation, new installation is not it? I loosed everthing, at the end I got the same desktop screen like Ubuntu 11.10. Anybody knows about what gone wrong and if any possibility to recover my datas? Please help me. I want to Know that which method is stable to Upgrade existing Ubunt11.10

  • gl_PointCoord always zero

    - by Jonathan
    I am trying to draw point sprites in OpenGL with a shader but gl_PointCoord is always zero. Here is my code Setup: //Shader creation..(includes glBindAttribLocation(program, ATTRIB_P, "p");) glEnableVertexAttribArray(ATTRIB_P); In the rendering loop: glUseProgram(shader_particles); float vertices[]={0.0f,0.0f,0.0f}; glEnable(GL_TEXTURE_2D); glEnable(GL_POINT_SPRITE); glEnable(GL_VERTEX_PROGRAM_POINT_SIZE); //glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE);(tried with this on/off, doesn't work) glVertexAttribPointer(ATTRIB_P, 3, GL_FLOAT, GL_FALSE, 0, vertices); glDrawArrays(GL_POINTS, 0, 1); Vertex Shader: attribute highp vec4 p; void main() { gl_PointSize = 40.0f; gl_Position = p; } Fragment Shader: void main() { gl_FragColor = vec4(gl_PointCoord.st, 0, 1);//if the coords range from 0-1, this should draw a square with black,red,green,yellow corners } But this only draws a black square with a size of 40. What am I doing wrong? Edit: Point sprites work when i use the fixed function, but I need to use shaders because in the end the code will be for opengl es 2.0 glUseProgram(0); glEnable(GL_TEXTURE_2D); glEnable(GL_POINT_SPRITE); glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE); glPointSize(40); glBegin(GL_POINTS); glVertex3f(0.0f,0.0f,0.0f); glEnd(); Is anyone able to get point sprites working with shader? If so, please share some code.

  • My Optimized Adam &amp; Eve

    - by MarkPearl
    Today I had a few minutes in the evening to go over my original Adam and Eve code… what I wanted to see tonight was if I could optimize the code any further… which I was pretty sure could be done. Ultimately what I wanted to find from the experiment was a balance between optimized code an reusable code. On the one hand I can put everything into a single function and end up with a totally unusable function that is extremely compressed, which would have big comebacks when making modifications at a later stage. Alternatively I could have many single line functions that are extremely loosely coupled but sparsely spaced and so would almost be to fragmented to grok. Ultimately I found with my current iteration something that I consider readable, yet compressed. Code below… // Learn more about F# at http://fsharp.net open System let people = [ ("Adam", None); ("Eve", None); ("Cain", Some("Adam", "Eve")); ("Abel", Some("Adam", "Eve")) ] // // Prints the details // let showDetails(person : string * (string * string) option) = let ParentsName = let parents = snd(person) match parents with | Some(dad, mum) -> "Father " + dad + " and Mother " + mum | None -> "Has no parents!" let result = fst(person) + Environment.NewLine + ParentsName result // // Searches an array of people and looks for a match of names // let findPerson(name : string, people : (string * (string * string) option) list) = // Try and find a match of the name let o = Seq.tryFind(fun person -> match name with | firstName when firstName = fst(person) -> true | _ -> false) people // Show the details based on the match result match o with | Option.Some(x) -> showDetails(Option.get(o)) | _ -> "Not Found" Console.WriteLine(findPerson("Cains", people)) Console.ReadLine()

  • How should you approach supporting rapidly-updating web browsers?

    - by Schnapple
    Today, Firefox 5 was released. If all goes according to plan, Firefox 7 will be out by the end of the year. Firefox has adopted the Google Chrome development model wherein version numbers are largely unimportant and so just supporting "the latest (publicly available) one" is probably the best strategy. But how do you best test that? As my QA guys have pointed out, if you tell the client that you support "the latest version" but a version comes out that breaks your site, then you have a problem because now you've stated you support a web browser you don't. And since both Firefox and Chrome now update themselves automatically, the average person probably has no clue or care what version they're running. And having them either not upgrade or roll back is nontrivial. I'm finding there are a number of organizations that mandate their employees use IE (the head of IT subscribes to the Microsoft school of thought), or mandate their employees use Firefox (the head of IT subscribes to the IE-is-insecure school of thought), so Chrome updating constantly was a non-issue. But now that Firefox is a member of that club, I can see this becoming a bigger issue soon. My guess, in the case of Firefox, would be that the Aurora channel is the key, but what is the best way to approach testing it? Should we fix anything that comes up as an issue in Aurora, or should we wait until closer to the scheduled release? Do people automate this sort of thing?

  • The 'desktops' move to Oracle

    - by [email protected]
    The move to Oracle has been most interesting.  Here we have an organization who are interested in what they are interested in.  Not so much in things that aren't 'core'. The legacy Sun desktop products are things that Oracle is interested in.  To that end there are some changes coming to policies and products - and from my perspective they are all good. Very good. One of the changes to the Product suite is that we are now referred to as part of the Virtualization team, falling under Oracle's Chief Corporate Archtiect, Edward Screven.  Edward says that the Products were a 'gem' found inside the great pile of stuff that was Sun. Another change is that while StarOffice/Open Office has been certainly endorsed by Oracle, and it also falls under Edward's purview, and here has been a push on to use it as opposed to... well... you know.    It is not, however, part of the Virtualization team's product suite any more. There are some other really interesting changes coming that you will hear about quite soon.  The big message for today, though, is that Sun Rays, Secure Global Desktop, VirtualBox, and Oracle VDI software are all still alive and kicking and moving forward.  Infact, at the Oracle earnings call last week, Charles Phillips announced more significant wins with Sun Rays in the US Federal Governmnet space.  He could have talked about all kinds of legacy Sun products, but chose to mention Sun Rays in the first Quarterly statement since the acquisition of Sun - you should see this as a very good sign indeed. More soon - until then...

  • New Trusted Status awarded to first Mobile Java Developer

    - by Jacob Lehrbaum
    Java Verified has just announced that GameLoft is the first developer to receive its new Trusted Status!  Java Verified is an industry-recognized Java testing and signing program backed and funded by companies such as AT&T, LG, Motorola, Nokia, Oracle, Orange, Samsung and Vodafone, and chartered with making it easier for mobile developers to certify and deploy applications for use across the billions of mobile handsets that run the Java ME.  Because of its breadth and diversity, Java ME provides an unmatched opportunity to reach more than 3 billions consumers, but at the same time, developers are faced with the challenge of working with multiple distribution channels and a range of handsets. To this end, the Java Verified program provides a suite of tests that help to validate identity, functionality, integrity, and quality.  Since its rebirth in 2010 as an independent organization, the Java Verified program has been actively working to make it even easier to create and distribute Java ME apps.  Example initiatives include updates to the Unified Testing Criteria to make it easier to test "Simple Apps," community outreach to better understand and address developer pain-points  and a new "Trusted Status."  In the words of the Java Verified Program, Trusted Status is:a privileged status to be granted to developers who will have proven that the quality of their Java ME apps is of a consistently high standard. These are developers who will have earned the trust of Java Verified by demonstrating unfailingly that testing to the UTC standard is a crucial part of their product development activityThe first developer to be awarded this status is GameLoft.  By achieving Trusted Status Gameloft can now test their applications to the Java Verified standard without needing to provide Java Verified with the evidence.  The apps then automatically get signed with the Java Verified signature enabling GameLoft to benefit from reduced costs and time-to-market for their new Java ME applications from here on out.  Learn more about the exciting news or apply now for Trusted Status!

  • What Is A Software Architect&rsquo;s Job Today?

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/10/25/what-is-a-software-architectrsquos-job-today.aspx It was 2001 when a project manager first put my job title as architect on a statement of work.  A lot has changed over the last twelve years.  The concepts around what an architect is has evolved.  In the early days I would have said that they just rebranded the role of the system analyst.  Now we have a multitude of architect titles: application, solution, IT, data, enterprise.  Whatever the title the goals are the same.  An architect takes the business needs and maps them to the solutions that are needed and at the same time works to ensure the quality of the solution and its maintainability. One of the problems I see these days is that we are expecting every developer to have architect skills.  That in itself is not a problem.  This reduces the need for dedicated architects.  Not every developer though is going to be able to step up to this level.  Some are just good at solving small problems instead of thinking in the larger abstract. Another problem is the accelerating speed and breadth of new technologies and products.  For an architect to be good at his job he needs to spend large amounts of personal time studying just to stay relevant. In the end I don’t think the main objectives of an architect has changed, just the level of commitment needed to stay of value to your company.  Renew your commitment to your profession and keep delivering great solutions.

  • What makes a Software Craftsman?

    - by Liam McLennan
    At the end of my visit to 8th Light Justin Martin was kind enough to give me a ride to the train station; for my train back to O’Hare. Just before he left he asked me an interesting question which I then posted to twitter: Liam McLennan: . @JustinMartinM asked what I think is the most important attributes of craftsmen. I said, "desire to learn and humility". What's yours? 6:25 AM Apr 17th via TweetDeck several people replied with excellent contributions: Alex Hung: @liammclennan I think kaizen sums up craftmanship pretty well, which is almost same as yours Steve Bohlen: @alexhung @liammclennan those are both all about saying "knowing what you don't know and not being afraid to go learn it" (and I agree!) Matt Roman: @liammclennan @JustinMartinM a tempered compulsion for constant improvement, and an awareness of what needs improving. Justin Martin: @mattroman @liammclennan a faculty for asking challenging questions, and a persistence to battle through difficult obstacles barring growth I thought this was an interesting conversation, and I would love to see other people contribute their opinions. My observation is that Alex, Steve, Matt and I seem to have essentially the same answer in different words. It is also interesting to note (as Alex pointed out) that these definitions are very similar to Alt.NET and the lean concept of kaizen.

  • IASA South East Florida Chapter Meeting Recap - June 2011

    - by Sam Abraham
    Erik Russell and Giles Marino were our speakers for the June 2011 IASA South East Florida Chapter meeting.    Attendees filled all available seats at the Microsoft office conference room where the event was held. This highlights the high interest in Enterprise Architecture as a career track and chartered project role. Also in attendance were our Board of Directors and Alex Funkhouser, President, Sherlock Technology.   Rainer Habermann, Chapter President, kicked off the meeting by introducing our speakers and Board of Directors.   Alex Funkhouser, President of South Florida’s staffing firm Sherlock Technology spoke briefly about available Software Architect positions in the area. Alex also congratulated and presented this week’s Sherlock Raffle winner with $500 in cash.   Our speakers Giles and Erik then proceeded with their talk. Erik presented a business case in the government sector where Enterprise Architecture helped a government entity cut costs and streamline its various business operations. Technologies leveraged in Erik’s demonstrated project were Java-based.   Giles then followed with a thorough demonstration of the Architecture patterns he used to migrate a complete backend system for an insurance company to the .Net Platform.   Audience was very engaged with our speakers as evidenced by the large number of follow-up questions asked at the end of the talk.   We greatly enjoyed Giles and Erik’s talk and look forward to having them share with us more of their adventures as Enterprise Architects in the near future.   Below are some photos of the event.   Sam Abraham Secretary- IASA South East Florida Chapter. http://www.iasaglobal.org/iasa/South_East_Florida.asp Chapter President - Rainer Habermann kicks off our meeting.   Sherlock Technology President Alex Funkhouser holding Sherlock's weekly cash prize.

  • Retro Video Game Collection

    - by Matt Christian
    Recently I've decided, in true nerd fashion, to collect either comic books or video games.  Considering I'm much more versed in the technological arts and not in ACTUAL art, I thought collecting old video games would be an interesting venture.  After all, I am a self-described compulsive shopper (my bank statement at the end of the month has a purchase every few days).  (Don't worry, I'm not in debt and still pay my bills on time!) I went to a local video game store in Stevens Point called Gaming Generations which is a neat little shop with loads of old games for great prices.  For example, any NES cartridge on the shelf (not behind glass) is, at most, $4.99 with the cheaper ones around $1.99.  During my first round at GG, I picked up the following: NES: - Fester's Quest - Adventures of Link (Zelda 2, grey cart) - Little Nemo - Total Recall - The Goonies 2 PSX: - Galerians N64: - Mission: Impossible - Hybrid Heaven I was a little cautious, would I even like collecting old games?  As soon as I popped a few of those games in I knew right away the answer was an astounding YES!  Not only is it fun to bring back memories of all these old games, but searching for them in stores is also a blast and saying 'I have that one, I need the second one.' After finding such joy in buying these games, I decided to go search through 4-5 stores in Wausau for old games as well.  While the prices were a bit higher and selection smaller, the search was still fun.  I found the following: NES: - Maniac Mansion - T&C Surf - Chip N Dale: Rescue Rangers - TMNT (the first one) - Mission: Impossible N64: - Turok - Turok 2 Genesis: - Sonic the Hedgehog Dreamcast: - Shenmue And I found a Gamegear for $5!  Now I just need to find games for it... Tonight I will go on one more small expedition into the used, once again stopping at GG and another second hand store to see if I can find any items for my collection.

    by Peter Reiser  - Social Business Evangelist, Oracle WebCenter  Tom Petrocelli of Enterprise Strategy Group published a report recently, “Oracle Social Network: The Social Glue for Enterprise Applications”, on Oracle Social Network (OSN) and how traditional social products create social silos whereas OSN is the “social glue” for enterprise applications.  This report supports the point of Oracle’s Social Business Strategy to seamless integrate social capabilities into the main business processes. Quote from report: “Oracle has adopted the correct approach to creating a social layer and socially enabled applications. Oracle Social Network is not simply another enterprise social network product; it is a complete social layer for the enterprise application stack. This approach will serve Oracle users well in the future.” OSN allow to capture the related Conversations of a business process right where it’s happens – within the respective Business application.  Fusion CRM is an excellent example for this approach. Quote from report: “Oracle’s new software, Oracle Social Network, is an example of a solution to the silo problem. While Oracle fields a typical enterprise social network application with microblogging, file sharing, shared documents or wikis, and activity streams, the front-end application is only a small part of what Oracle Social Network does. Instead, Oracle Social Network is a platform that provides social features as a service to other enterprise applications. In effect, Oracle Social Network socially enables all of Oracle’s enterprise applications—all enterprise applications really—with not only the same features, but also the same conversations. As a result, the social conversations act as a conduit for inter-application communication and collaboration.” Source: ESG Research Report, Oracle Social Network: The Social Glue for Enterprise Applications, August 2012.

  • Looking ahead at 2011-with Paul Greenberg

    - by divya.malik
    It is almost the end of 2010, rather unbelievable how fast this year has gone by. It is always interesting to read what our CRM gurus have to say about the coming year. So here is CRM luminary, Paul Greenberg’s  forecast for 2011. Mobile CRM growth accelerates. CRM and “Social” companies continue to integrate their capabilities as a few suites begin to emerge. Social “rankings”, as a measure of customer engagement, will become a standard public measure. Analytics exhibits the most significant growth of any area with Customer Insight apps leading the way. Marketing apps mature with social marketing becoming an integral part of the application offering. Customer service begins to redefine itself with greater emphasis on service communities, web self-service and customer knowledge capture. Knowledge management replaces enterprise content management as a core requirement for large businesses. Customer experience reasserts itself loudly as the core of CRM and SCRM - This one is kind of a no-brainer in a way. Co-creation and customer driven product innovation becomes more than just an advanced idea. Microsoft Azure emerges as a true cloud provider at the level of Amazon as cloud computing considers its rise to becoming a primary technology infrastructure. Application marketplaces will become commonplace as companies look to platform providers to fill ecosystem needs, not just CRM. I do encourage you to read the details of his forecasts, that are split into two blog posts. For Part I click here and for Part II, click here. Technorati Tags: oracle,siebel CRM,scrm,paul greenberg

  • Escaping Generics with T4 Templates

    - by Gavin Stevens
    I've been doing some work with T4 templates lately and ran into an issue which I couldn't find an answer to anywhere.  I finally figured it out, so I thought I'd share the solution. I was trying to generate a code class with a T4 template which used generics The end result a method like: public IEnumerator GetEnumerator()             {                 return new TableEnumerator<Table>(_page);             } the related section of the T4 template looks like this:  public IEnumerator GetEnumerator()             {                 return new TableEnumerator<#=renderClass.Name#>(_page);             } But this of course is missing the Generic Syntax for < > which T4 complains about because < > are reserved. using syntax like <#<#><#=renderClass.Name#><#=<#> won't work becasue the TextTransformation engine chokes on them.  resulting in : Error 2 The number of opening brackets ('<#') does not match the number of closing brackets ('#>')  even trying to escape the characters won't work: <#\<#><#=renderClass.Name#><#\<#> this results in: Error 4 A Statement cannot appear after the first class feature in the template. Only boilerplate, expressions and other class features are allowed after the first class feature block.  The final solution delcares a few strings to represent the literals like this: <#+    void RenderCollectionEnumerator(RenderCollection renderClass)  {     string open = "<";   string close =">"; #>    public partial class <#=renderClass.Name#> : IEnumerable         {             private readonly PageBase _page;             public <#=renderClass.Name#>(PageBase page)             {                 _page = page;             }             public IEnumerator GetEnumerator()             {                 return new TableEnumerator<#=open#><#=renderClass.Name#><#=close#>(_page);             }         } <#+  }  #> This works, and everyone is happy, resulting in an automatically generated class enumerator, complete with generics! Hopefully this will save someone some time :)

  • Ground Control by David Baum

    - by JuergenKress
    As cloud computing moves out of the early-adopter phase, organizations are carefully evaluating how to get to the cloud. They are examining standard methods for developing, integrating, deploying, and scaling their cloud applications, and after weighing their choices, they are choosing to develop and deploy cloud applications based on Oracle Cloud Application Foundation, part of Oracle Fusion Middleware. Oracle WebLogic Server is the flagship software product of Oracle Cloud Application Foundation. Oracle WebLogic Server is optimized to run on Oracle Exalogic Elastic Cloud, the integrated hardware and software platform for the Oracle Cloud Application Foundation family. Many companies, including Reliance Commercial Finance, are adopting this middleware infrastructure to enable private cloud computing and its convenient, on-demand access to a shared pool of configurable computing resources. “Cloud computing has become an extremely critical design factor for us,” says Shashi Kumar Ravulapaty, senior vice president and chief technology officer at Reliance Commercial Finance. “It’s one of our main focus areas. Oracle Exalogic, especially in combination with Oracle WebLogic, is a perfect fit for rapidly provisioning capacity in a private cloud infrastructure.” Reliance Commercial Finance provides loans to tens of thousands of customers throughout India. With more than 1,500 employees accessing the company’s core business applications every day, the company was having trouble processing more than 6,000 daily transactions with its legacy infrastructure, especially at the end of each month when hundreds of concurrent users need to access the company’s loan processing and approval applications.

  • Ingredient Substitutes while Baking

    - by Rekha
    In our normal cooking, we substitute the vegetables for the gravies we prepare. When we start baking, we look for a good recipe. At least one or two ingredient will be missing. We do not know where to substitute what to bring same output. So we finally drop the plan of baking. Again after a month, we get the interest in baking. Again one or two lack of ingredient and that’s it. We keep on doing this for months. When I was going through the cooking blogs, I came across a site with the Ingredient Substitutes for Baking: (*) is to indicate that this substitution is ideal from personal experience. Flour Substitutes ( For 1 cup of Flour) All Purpose Flour 1/2 cup white cake flour plus 1/2 cup whole wheat flour 1 cup self-rising flour (omit using salt and baking powder if the recipe calls for it since self raising flour has it already) 1 cup plus 2 tablespoons cake flour 1/2 cup (75 grams) whole wheat flour 7/8 cup (130 grams) rice flour (starch) (do not replace all of the flour with the rice flour) 7/8 cup whole wheat Bread Flour 1 cup all purpose flour 1 cup all purpose flour plus 1 teaspoon wheat gluten (*) Cake Flour Place 2 tbsp cornstarch in 1 cup and fill the rest up with All Purpose flour (*) 1 cup all purpose flour minus 2 tablespoons Pastry flour Place 2 tbsp cornstarch in 1 cup and fill the rest up with All Purpose flour Equal parts of All purpose flour plus cake flour (*) Self-rising Flour 1½ teaspoons of baking powder plus ½ teaspoon of salt plus 1 cup of all-purpose flour. Cornstarch (1 tbsp) 2 tablespoons all-purpose flour 1 tablespoon arrowroot 4 teaspoons quick-cooking tapioca 1 tablespoon potato starch or rice starch or flour Tapioca (1 tbsp) 1 – 1/2 tablespoons all-purpose flour Cornmeal (stone ground) polenta OR corn flour (gives baked goods a lighter texture) if using cornmeal for breading,crush corn chips in a blender until they have the consistency of cornmeal. maize meal Corn grits Sweeteners ( for Every 1 cup ) * * (HV) denotes Healthy Version for low fat or fat free substitution in Baking Light Brown Sugar 2 tablespoons molasses plus 1 cup of white sugar Dark Brown Sugar 3 tablespoons molasses plus 1 cup of white sugar Confectioner’s/Powdered Sugar Process 1 cup sugar plus 1 tablespoon cornstarch Corn Syrup 1 cup sugar plus 1/4 cup water 1 cup Golden Syrup 1 cup honey (may be little sweeter) 1 cup molasses Golden Syrup Combine two parts light corn syrup plus one part molasses 1/2 cup honey plus 1/2 cup corn syrup 1 cup maple syrup 1 cup corn syrup Honey 1- 1/4 cups sugar plus 1/4 cup water 3/4 cup maple syrup plus 1/2 cup granulated sugar 3/4 cup corn syrup plus 1/2 cup granulated sugar 3/4 cup light molasses plus 1/2 cup granulated white sugar 1 1/4 cups granulated white or brown sugar plus 1/4 cup additional liquid in recipe plus 1/2 teaspoon cream of tartar Maple Syrup 1 cup honey,thinned with water or fruit juice like apple 3/4 cup corn syrup plus 1/4 cup butter 1 cup Brown Rice Syrup 1 cup Brown sugar (in case of cereals) 1 cup light molasses (on pancakes, cereals etc) 1 cup granulated sugar for every 3/4 cup of maple syrup and increase liquid in the recipe by 3 tbsp for every cup of sugar.If baking soda is used, decrease the amount by 1/4 teaspoon per cup of sugar substituted, since sugar is less acidic than maple syrup Molasses 1 cup honey 1 cup dark corn syrup 1 cup maple syrup 3/4 cup brown sugar warmed and dissolved in 1/4 cup of liquid ( use this if taste of molasses is important in the baked good) Cocoa Powder (Natural, Unsweetened) 3 tablespoons (20 grams) Dutch-processed cocoa plus 1/8 teaspoon cream of tartar, lemon juice or white vinegar 1 ounce (30 grams) unsweetened chocolate (reduce fat in recipe by 1 tablespoon) 3 tablespoons (20 grams) carob powder Semisweet baking chocolate (1 oz) 1 oz unsweetened baking chocolate plus 1 Tbsp sugar Unsweetened baking chocolate (1 oz ) 3 Tbsp baking cocoa plus 1 Tbsp vegetable oil or melted shortening or margarine Semisweet chocolate chips (1 cup) 6 oz semisweet baking chocolate, chopped (Alternatively) For 1 cup of Semi sweet chocolate chips you can use : 6 tablespoons unsweetened cocoa powder, 7 tablespoons sugar ,1/4 cup fat (butter or oil) Leaveners and Diary * * (HV) denotes Healthy Version for low fat or fat free substitution in Baking Compressed Yeast (1 cake) 1 envelope or 2 teaspoons active dry yeast 1 packet (1/4 ounce) Active Dry yeast 1 cake fresh compressed yeast 1 tablespoon fast-rising active yeast Baking Powder (1 tsp) 1/3 teaspoon baking soda plus 1/2 teaspoon cream of tartar 1/2 teaspoon baking soda plus 1/2 cup buttermilk or plain yogurt 1/4 teaspoon baking soda plus 1/3 cup molasses. When using the substitutions that include liquid, reduce other liquid in recipe accordingly Baking Soda(1 tsp) 3 tsp Baking Powder ( and reduce the acidic ingredients in the recipe. Ex Instead of buttermilk add milk) 1 tsp potassium bicarbonate Ideal substitution – 2 tsp Baking powder and omit salt in recipe Cream of tartar (1 tsp) 1 teaspoon white vinegar 1 tsp lemon juice Notes from What’s Cooking America – If cream of tartar is used along with baking soda in a cake or cookie recipe, omit both and use baking powder instead. If it calls for baking soda and cream of tarter, just use baking powder.Normally, when cream of tartar is used in a cookie, it is used together with baking soda. The two of them combined work like double-acting baking powder. When substituting for cream of tartar, you must also substitute for the baking soda. If your recipe calls for baking soda and cream of tarter, just use baking powder. One teaspoon baking powder is equivalent to 1/4 teaspoon baking soda plus 5/8 teaspoon cream of tartar. If there is additional baking soda that does not fit into the equation, simply add it to the batter. Buttermilk (1 cup) 1 tablespoon lemon juice or vinegar (white or cider) plus enough milk to make 1 cup (let stand 5-10 minutes) 1 cup plain or low fat yogurt 1 cup sour cream 1 cup water plus 1/4 cup buttermilk powder 1 cup milk plus 1 1/2 – 1 3/4 teaspoons cream of tartar Plain Yogurt (1 cup) 1 cup sour cream 1 cup buttermilk 1 cup crème fraiche 1 cup heavy whipping cream (35% butterfat) plus 1 tablespoon freshly squeezed lemon juice Whole Milk (1 cup) 1 cup fat free milk plus 1 tbsp unsaturated Oil like canola (HV) 1 cup low fat milk (HV) Heavy Cream (1 cup) 3/4 cup milk plus 1/3 cup melted butter.(whipping wont work) Sour Cream (1 cup) (pls refer also Substitutes for Fats in Baking below) 7/8 cup buttermilk or sour milk plus 3 tablespoons butter. 1 cup thickened yogurt plus 1 teaspoon baking soda. 3/4 cup sour milk plus 1/3 cup butter. 3/4 cup buttermilk plus 1/3 cup butter. Cooked sauces: 1 cup yogurt plus 1 tablespoon flour plus 2 teaspoons water. Cooked sauces: 1 cup evaporated milk plus 1 tablespoon vinegar or lemon juice. Let stand 5 minutes to thicken. Dips: 1 cup yogurt (drain through a cheesecloth-lined sieve for 30 minutes in the refrigerator for a thicker texture). Dips: 1 cup cottage cheese plus 1/4 cup yogurt or buttermilk, briefly whirled in a blender. Dips: 6 ounces cream cheese plus 3 tablespoons milk,briefly whirled in a blender. Lower fat: 1 cup low-fat cottage cheese plus 1 tablespoon lemon juice plus 2 tablespoons skim milk, whipped until smooth in a blender. Lower fat: 1 can chilled evaporated milk whipped with 1 teaspoon lemon juice. 1 cup plain yogurt plus 1 tablespoon cornstarch 1 cup plain nonfat yogurt Substitutes for Fats in Baking * * (HV) denoted Healthy Version for low fat or fat free substitution in Baking Butter (1 cup) 1 cup trans-free vegetable shortening 3/4 cups of vegetable oil (example. Canola oil) Fruit purees (example- applesauce, pureed prunes, baby-food fruits). Add it along with some vegetable oil and reduce any other sweeteners needed in the recipe since fruit purees are already sweet. 1 cup polyunsaturated margarine (HV) 3/4 cup polyunsaturated oil like safflower oil (HV) 1 cup mild olive oil (not extra virgin)(HV) Note: Butter creates the flakiness and the richness which an oil/purees cant provide. If you don’t want to compromise that much to taste, replace half the butter with the substitutions. Shortening(1 cup) 1 cup polyunsaturated margarine like Earth Balance or Smart Balance(HV) 1 cup + 2tbsp Butter ( better tasting than shortening but more expensive and has cholesterol and a higher level of saturated fat; makes cookies less crunchy, bread crusts more crispy) 1 cup + 2 tbsp Margarine (better tasting than shortening but more expensive; makes cookies less crunchy, bread crusts tougher) 1 Cup – 2tbsp Lard (Has cholesterol and a higher level of saturated fat) Oil equal amount of apple sauce stiffly beaten egg whites into batter equal parts mashed banana equal parts yogurt prune puree grated raw zucchini or seeds removed if cooked. Works well in quick breads/muffins/coffee cakes and does not alter taste pumpkin puree (if the recipe can handle the taste change) Low fat cottage cheese (use only half of the required fat in the recipe). Can give rubbery texture to the end result Silken Tofu – (use only half of the required fat in the recipe). Can give rubbery texture to the end result Equal parts of fruit juice Note: Fruit purees can alter the taste of the final product is used in large quantities. Cream Cheese (1 cup) 4 tbsps. margarine plus 1 cup low-fat cottage cheese – blended. Add few teaspoons of fat-free milk if needed (HV) Heavy Cream (1 cup) 1 cup evaporated skim milk (or full fat milk) 1/2 cup low fat Yogurt plus 1/2 low fat Cottage Cheese (HV) 1/2 cup Yogurt plus 1/2 Cottage Cheese Sour Cream (1 cup) 1 cup plain yogurt (HV) 3/4 cup buttermilk or plain yogurt plus 1/3 cup melted butter 1 cup crème fraiche 1 tablespoon lemon juice or vinegar plus enough whole milk to fill 1 cup (let stand 5-10 minutes) 1/2 cup low-fat cottage cheese plus 1/2 cup low-fat or nonfat yogurt (HV) 1 cup fat-free sour cream (HV) Note: How to Make Maple Syrup Substitute at home For 1 Cup Maple Syrup 1/2 cup granulated sugar 1 cup brown sugar, firmly packed 1 cup boiling water 1 teaspoon butter 1 teaspoon maple extract or vanilla extract Method In a heavy saucepan, place the granulated sugar and keep stirring until it melts and turns slightly brown. Alternatively in another pan, place brown sugar and water and bring to a boil without stirring. Now mix both the sugars and simmer in low heat until they come together as one thick syrup. Remove from heat, add butter and the extract. Use this in place of maple syrup. Store it in a fridge in an air tight container. Even though this was posted in their site long back, I found it helpful. So posting it for you. via chefinyou . cc image credit: flickr/zetrules

  • ASP 3.0 Folder/File Permissions Settings (ASP Classic)

    - by ASP Pee-Wee
    Dear Stack Exchange, Hi, I have built a form input page in HTML that has an action to post to an ASP handler/processor .asp file. The form handler/processor .asp file contains only <% Insert VBScript Here % and no HTML output whatsoever. The .asp file was never intended to be a "web viewable" .asp file like an .asp home page file or html file would. It's supposed to be for my eyes only- not the public's however it does need to take info posted by the public and do something with it on it's end. I have used VBScript/ASP3.0 to build the form handler/processor file and would like to know how to keep someone from viewing the actual VBScript in the handler/processor .asp file. I am aware of obfuscation but I would like to know how to keep prying eyes from even being able to take a look at the obfuscated code in the handler/processor file. I realize that the server executes the .asp file first before outputting anything to the browser so I guess that my main concern is mostly that someone may could "download" the form handler/processor .asp file, then view it's contents on their machine. Assuming the form handler .asp file is where it is, behind the root, and is on a windows server (no htaccess approach) how could one protect it so that it could never be viewed or simply pulled down via anonymous ftp or something like that? Is there something like "script only" permissions that the system administrator could set up for a particular folder? Remember, with shared hosting I can't go above the root. If so, would the form still be able to post? How would any of you guys go about protecting the asp file in addition to obfuscation? Any help would be greatly appreciated. Thanks, ASP Pee-Wee

  • Imperative vs. LINQ Performance on WP7

    - by Bil Simser
    Jesse Liberty had a nice post presenting the concepts around imperative, LINQ and fluent programming to populate a listbox. Check out the post as it’s a great example of some foundational things every .NET programmer should know. I was more interested in what the IL code that would be generated from imperative vs. LINQ was like and what the performance numbers are and how they differ. The code at the instruction level is interesting but not surprising. The imperative example with it’s creating lists and loops weighs in at about 60 instructions. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace;

In fact if you have ReSharper installed you’ll see a squiggly (technical term) in the imperative code that says “Hey Dude, I can convert this to LINQ if you want to be c00L!” (or something like that, it’s the 2010 geek version of Clippy). What about the fluent version? As Jon correctly pointed out in the comments, when you compare the IL for the LINQ code and the IL for the fluent code it’s the same. LINQ and the fluent interface are just syntactical sugar so you decide what you’re most comfortable with. At the end of the day they’re both the same. Now onto the numbers. Again I expected the imperative version to be better performing than the LINQ version (before I saw the IL that was generated). Call it womanly instinct. A gut feel. Whatever. Some of the numbers are interesting though. For Jesse’s example of 50 items, the numbers were interesting. The imperative sample clocked in at 7ms while the LINQ version completed in 4. As the number of items went up, the elapsed time didn’t necessarily climb exponentially. At 500 items they were pretty much the same and the results were similar up to about 50,000 items. After that I tried 500,000 items where the gap widened but not by much (2.2 seconds for imperative, 2.3 for LINQ). It wasn’t until I tried 5,000,000 items where things were noticeable. Imperative filled the list in 20 seconds while LINQ took 8 seconds longer (although personally I wouldn’t suggest you put 5 million items in a list unless you want your users showing up at your door with torches and pitchforks). Here’s the table with the full results. Method/Items 50 500 5,000 50,000 500,000 5,000,000 Imperative 7ms 7ms 38ms 223ms 2230ms 20974ms LINQ/Fluent 4ms 6ms 41ms 240ms 2310ms 28731ms Like I said, at the end of the day it’s not a huge difference and you really don’t want your users waiting around for 30 seconds on a mobile device filling lists. In fact if Windows Phone 7 detects you’re taking more than 10 seconds to do any one thing, it considers the app hung and shuts it down. The results here are for Windows Phone 7 but frankly they're the same for desktop and web apps so feel free to apply it generally. From a programming perspective, choose what you like. Some LINQ statements can get pretty hairy so I usually fall back with my simple mind and write it imperatively. If you really want to impress your friends, write it old school then let ReSharper do the hard work for! Happy programming!

  • Looking Back at MIX10

    - by WeigeltRo
    It’s the sad truth of my life that even though I’m fascinated by airplanes and flight in general since my childhood days, my body doesn’t like flying. Even the ridiculously short flights inside Germany are taking their toll on me each time. Now combine this with sitting in the cramped space of economy class for many hours on a transatlantic flight from Germany to Las Vegas and back, and factor in some heavy dose of jet lag (especially on my way eastwards), and you get an idea why after coming back home I had this question on my mind: Was it really worth it to attend MIX10? This of course is a question that will also be asked by my boss at Comma Soft (for other reasons, obviously), who decided to send me and my colleague Jens Schaller, to the MIX10 conference. (A note to my German readers: An dieser Stelle der Hinweis, dass Comma Soft noch Silverlight-Entwickler und/oder UI-Designer für den Standort Bonn sucht – aussagekräftige Bewerbungen bitte an [email protected]) Too keep things short: My answer is yes. Before I’ll go into detail, let me ask the heretical questions whether tech conferences in general still make sense. There was a time, where actually being at a tech conference gave you a head-start in regard to learning about new technologies. Nowadays this is no longer true, where every bit of information and every detail is immediately twittered, blogged and whatevered to death. In the case of MIX10 you even can download the video-taped sessions shortly after. So: Does visiting a conference still make sense? It depends on what you expect from a conference. It should be clear to everybody that you’ll neither get exclusive information, nor receive training in a small group. What a conference does offer that sitting in front of your computer does not can be summarized as follows: Focus Being away from work and home will help you to focus on the presented information. Of course there are always the poor guys who are haunted by their work (with mails and short text messages reporting the latest showstopper problem), but in general being out of your office makes a huge difference. Inspiration With the focus comes the emotional involvement. I find it much easier to absorb information if I feel that certain vibe when sitting in a session. This still means that I have put work into reviewing the information later, but it’s a better starting point. And all the impressions collected at a (good) conference combined lead to a higher motivation – be it by the buzz (“this is gonna be sooo cool!”) or by the fear to fall behind (“man, we’ll have work on this, or else…”). People At a conference it’s pretty easy to get into contact with other people during breakfast, lunch and other breaks. This is a good opportunity to get a feel for what other development teams are doing (on a very general level of course, nobody will tell you about their secret formula) and what they are thinking about specific technologies. So MIX10 did offer focus, inspiration and people, but that would have meant nothing without valuable content. When I (being a frontend developer with a strong interest in UI/UX) planned my visit to MIX10, I made the decision to focus on the "soft" topics of design, interaction and user experience. I figured that I would be bombarded with all the technical details about Silverlight 4 anyway in the weeks and months to come. Actually, I would have liked to catch a few technical sessions, but the agenda wasn’t exactly in favor of people interested in any kind of Silverlight and UI/UX/Design topics. That’s one of my few complaints about the conference – I would have liked one more day and/or more sessions per day. Overall, the quality of the workshops and sessions was pretty high. In fact, looking back at my collection of conferences I’ve visited in the past I’d say that MIX10 ranks somewhere near the top spot. Here’s an overview of the workshops/sessions I attended (I’ll leave out the keynotes): Day 0 (Workshops on Sunday) Design Fundamentals for Developers Robby Ingebretsen is the man! Great workshop in three parts with the perfect mix of examples, well-structured definition of terminology and the right dose of humor. Robby was part of the WPF team before founding his own company so he not only has a strong interest in design (and the skillz!) but also the technical background.   Design Tools and Techniques Originally announced to be held by Arturo Toledo, the Rosso brothers from ArcheType filled in for the first two parts, and Corrina Black had a pretty general part about the Windows Phone UI. The first two thirds were a mixed bag; the two guys definitely knew what they were talking about, and the demos were great, but the talk lacked the preparation and polish of a truly great presentation. Corrina was not allowed to go into too much detail before the keynote on Monday, but the session was still very interesting as it showed how much thought went into the Windows Phone UI (and there’s always a lot to learn when people talk about their thought process). Day 1 (Monday) Designing Rich Experiences for Data-Centric Applications I wonder whether there was ever a test-run for this session, but what Ken Azuma and Yoshihiro Saito delivered in the first 15 minutes of a 30-minutes-session made me walk out. A commercial for a product (just great: a video showing a SharePoint plug-in in an all-Japanese UI) combined with the most generic blah blah one could imagine. EPIC FAIL.   Great User Experiences: Seamlessly Blending Technology & Design I switched to this session from the one above but I guess I missed the interesting part – what I did catch was what looked like a “look at the cool stuff we did” without being helpful. Or maybe I was just in a bad mood after the other session.   The Art, Technology and Science of Reading This talk by Kevin Larson was very interesting, but was more a presentation of what Microsoft is doing in research (pretty impressive) and in the end lacked a bit the helpful advice one could have hoped for.   10 Ways to Attack a Design Problem and Come Out Winning Robby Ingebretsen again, and again a great mix of theory and practice. The clean and simple, yet effective, UI of the reader app resulted in a simultaneous “wow” of Jens and me. If you’d watch only one session video, this should be it. Microsoft has to bring Robby back next year! Day 2 (Tuesday) Touch in Public: Multi-touch Interaction Design for Kiosks & Architectural Experiences Very interesting session by Jason Brush, a great inspiration with many details to look out for in the examples. Exactly what I was hoping for – and then some!   Designing Bing: Heart and Science How hard can it be to design the UI for a search engine? An input field and a list of results, that should be it, right? Well, not so fast! The talk by Paul Ray showed the many iterations to finally get it right (up to the choice of a specific blue for the links). And yes, I want an eye-tracking device to play around with!   The Elephant in the Room When Nishant Kothary presented a long list of what his session was not about, I told to myself (not having the description text present) “Am I in the wrong talk? Should I leave?”. Boy, was I wrong. A great talk about human factors in the process of designing stuff.   An Hour with Bill Buxton Having seen Bill Buxton’s presentation in the keynote, I just had to see this man again – even though I didn’t know what to expect. Being more or less unplanned and intended to be more of a conversation, the session didn’t provide a wealth of immediately useful information. Nevertheless Bill Buxton was impressive with his huge knowledge of seemingly everything. But this could/should have been a session some when in the evening and not in parallel to at least two other interesting talks. Day 3 (Wednesday) Design the Ordinary, Like the Fixie This session by DL Byron and Kevin Tamura started really well and brought across the message to keep things simple. But towards the end the talk lost some of its steam. And, as a member of the audience pointed out, they kind of ignored their own advice when they used a fancy presentation software other then PowerPoint that sometimes got in the way of showing things.   Developing Natural User Interfaces Speaking of alternative presentation software, Joshua Blake definitely had the most remarkable alternative to PowerPoint, a self-written program called NaturalShow that was controlled using multi-touch on a touch screen. Not a PowerPoint-killer, but impressive nevertheless. The (excellent) talk itself was kind of eye-opening in regard to what “multi-touch support” on various platforms (WPF, Silverlight, Windows Phone) actually means.   Treat your Content Right The talk by Tiffani Jones Brown wasn’t even on my planned schedule, but somehow I ended up in that session – and it was great. And even for people who don’t necessarily have to write content for websites, some points made by Tiffani are valid in many places, notably wherever you put texts with more than a single word into your UI. Creating Effective Info Viz in Microsoft Silverlight The last session of MIX10 I attended was kind of disappointing. At first things were very promising, with Matthias Shapiro giving a brief but well-structured introduction to info graphics and interactive visualizations. Then the live-coding began and while the result was interesting, too much time was spend on wrestling to get the code working. Ending earlier than planned, the talk was a bit light on actual content, but at least it included a nice list of resources. Conclusion It could be felt all across MIX10, UIs will take a huge leap forward; in fact, there are enough examples that have already. People who both have the technical know-how and at least a basic understanding of design (“literacy” as Bill Buxton called it) are in high demand. The concept of the MIX conference and initiatives like design.toolbox shows that Microsoft understands very well that frontend developers have to acquire new knowledge besides knowing how to hack code and putting buttons on a form. There are extremely exciting times before us, with lots of opportunity for those who are eager to develop their skills, that is for sure.
