• Latency on mobile networks (Android)

  - by Meep3D

  I am planning to give mobile phone development a shot and was thinking about making some simple multiplayer games. I know latency over local wifi is probably fine but what are the issues with latency over GPRS/3G? I've searched and the best I've seen is someone saying it was 'high', without presenting any concrete numbers. I suppose latency fluctuations are important as well - does anyone have any info on this?

• What is this GUI principle called?

  - by ripper234

  "Prefer to design UI that guides the user to provide correct input before submitting a form over presenting an error message when he submits it incorrectly" Is there a canonical link that explains this (similar to KISS)?

• The Data Scientist

  - by BuckWoody

  A new term - well, perhaps not that new - has come up and I’m actually very excited about it. The term is Data Scientist, and since it’s new, it’s fairly undefined. I’ll explain what I think it means, and why I’m excited about it. In general, I’ve found the term deals at its most basic with analyzing data. Of course, we all do that, and the term itself in that definition is redundant. There is no science that I know of that does not work with analyzing lots of data. But the term seems to refer to more than the common practices of looking at data visually, putting it in a spreadsheet or report, or even using simple coding to examine data sets. The term Data Scientist (as far as I can make out this early in it’s use) is someone who has a strong understanding of data sources, relevance (statistical and otherwise) and processing methods as well as front-end displays of large sets of complicated data. Some - but not all - Business Intelligence professionals have these skills. In other cases, senior developers, database architects or others fill these needs, but in my experience, many lack the strong mathematical skills needed to make these choices properly. I’ve divided the knowledge base for someone that would wear this title into three large segments. It remains to be seen if a given Data Scientist would be responsible for knowing all these areas or would specialize. There are pretty high requirements on the math side, specifically in graduate-degree level statistics, but in my experience a company will only have a few of these folks, so they are expected to know quite a bit in each of these areas. Persistence The first area is finding, cleaning and storing the data. In some cases, no cleaning is done prior to storage - it’s just identified and the cleansing is done in a later step. This area is where the professional would be able to tell if a particular data set should be stored in a Relational Database Management System (RDBMS), across a set of key/value pair storage (NoSQL) or in a file system like HDFS (part of the Hadoop landscape) or other methods. Or do you examine the stream of data without storing it in another system at all? This is an important decision - it’s a foundation choice that deals not only with a lot of expense of purchasing systems or even using Cloud Computing (PaaS, SaaS or IaaS) to source it, but also the skillsets and other resources needed to care and feed the system for a long time. The Data Scientist sets something into motion that will probably outlast his or her career at a company or organization. Often these choices are made by senior developers, database administrators or architects in a company. But sometimes each of these has a certain bias towards making a decision one way or another. The Data Scientist would examine these choices in light of the data itself, starting perhaps even before the business requirements are created. The business may not even be aware of all the strategic and tactical data sources that they have access to. Processing Once the decision is made to store the data, the next set of decisions are based around how to process the data. An RDBMS scales well to a certain level, and provides a high degree of ACID compliance as well as offering a well-known set-based language to work with this data. In other cases, scale should be spread among multiple nodes (as in the case of Hadoop landscapes or NoSQL offerings) or even across a Cloud provider like Windows Azure Table Storage. In fact, in many cases - most of the ones I’m dealing with lately - the data should be split among multiple types of processing environments. This is a newer idea. Many data professionals simply pick a methodology (RDBMS with Star Schemas, NoSQL, etc.) and put all data there, regardless of its shape, processing needs and so on. A Data Scientist is familiar not only with the various processing methods, but how they work, so that they can choose the right one for a given need. This is a huge time commitment, hence the need for a dedicated title like this one. Presentation This is where the need for a Data Scientist is most often already being filled, sometimes with more or less success. The latest Business Intelligence systems are quite good at allowing you to create amazing graphics - but it’s the data behind the graphics that are the most important component of truly effective displays. This is where the mathematics requirement of the Data Scientist title is the most unforgiving. In fact, someone without a good foundation in statistics is not a good candidate for creating reports. Even a basic level of statistics can be dangerous. Anyone who works in analyzing data will tell you that there are multiple errors possible when data just seems right - and basic statistics bears out that you’re on the right track - that are only solvable when you understanding why the statistical formula works the way it does. And there are lots of ways of presenting data. Sometimes all you need is a “yes” or “no” answer that can only come after heavy analysis work. In that case, a simple e-mail might be all the reporting you need. In others, complex relationships and multiple components require a deep understanding of the various graphical methods of presenting data. Knowing which kind of chart, color, graphic or shape conveys a particular datum best is essential knowledge for the Data Scientist. Why I’m excited I love this area of study. I like math, stats, and computing technologies, but it goes beyond that. I love what data can do - how it can help an organization. I’ve been fortunate enough in my professional career these past two decades to work with lots of folks who perform this role at companies from aerospace to medical firms, from manufacturing to retail. Interestingly, the size of the company really isn’t germane here. I worked with one very small bio-tech (cryogenics) company that worked deeply with analysis of complex interrelated data. So  watch this space. No, I’m not leaving Azure or distributed computing or Microsoft. In fact, I think I’m perfectly situated to investigate this role further. We have a huge set of tools, from RDBMS to Hadoop to allow me to explore. And I’m happy to share what I learn along the way.

• Microsoft Business Intelligence Seminar 2011

  - by DavidWimbush

  I was lucky enough to attend the maiden presentation of this at Microsoft Reading yesterday. It was pretty gripping stuff not only because of what was said but also because of what could only be hinted at. Here's what I took away from the day. (Disclaimer: I'm not a BI guru, just a reasonably experienced BI developer, so I may have misunderstood or misinterpreted a few things. Particularly when so much of the talk was about the vision and subtle hints of what is coming. Please comment if you think I've got anything wrong. I'm also not going to even try to cover Master Data Services as I struggled to imagine how you would actually use it.) I was a bit worried when I learned that the whole day was going to be presented by one guy but Rafal Lukawiecki is a very engaging speaker. He's going to be presenting this about 20 times around the world over the coming months. If you get a chance to hear him speak, I say go for it. No doubt some of the hints will become clearer as Denali gets closer to RTM. Firstly, things are definitely happening in the SQL Server Reporting and BI world. Traditionally IT would build a data warehouse, then cubes on top of that, and then publish them in a structured and controlled way. But, just as with many IT projects in general, by the time it's finished the business has moved on and the system no longer meets their requirements. This not sustainable and something more agile is needed but there has to be some control. Apparently we're going to be hearing the catchphrase 'Balancing agility with control' a lot. More users want more access to more data. Can they define what they want? Of course not, but they'll recognise it when they see it. It's estimated that only 28% of potential BI users have meaningful access to the data they need, so there is a real pent-up demand. The answer looks like: give them some self-service tools so they can experiment and see what works, and then IT can help to support the results. It's estimated that 32% of Excel users are comfortable with its analysis tools such as pivot tables. It's the power user's preferred tool. Why fight it? That's why PowerPivot is an Excel add-in and that's why they released a Data Mining add-in for it as well. It does appear that the strategy is going to be to use Reporting Services (in SharePoint mode), PowerPivot, and possibly something new (smiles and hints but no details) to create reports and explore data. Everything will be published and managed in SharePoint which gives users the ability to mash-up, share and socialise what they've found out. SharePoint also gives IT tools to understand what people are looking at and where to concentrate effort. If PowerPivot report X becomes widely used, it's time to check that it shows what they think it does and perhaps get it a bit more under central control. There was more SharePoint detail that went slightly over my head regarding where Excel Services and Excel Web Application fit in, the differences between them, and the suggestion that it is likely they will one day become one (but not in the immediate future). That basic pattern is set to be expanded upon by further exploiting Vertipaq (the columnar indexing engine that enables PowerPivot to store and process a lot of data fast and in a small memory footprint) to provide scalability 'from the desktop to the data centre', and some yet to be detailed advances in 'frictionless deployment' (part of which is about making the difference between local and the cloud pretty much irrelevant). Excel looks like becoming Microsoft's primary BI client. It already has: the ability to consume cubes strong visualisation tools slicers (which are part of Excel not PowerPivot) a data mining add-in PowerPivot A major hurdle for self-service BI is presenting the data in a consumable format. You can't just give users PowerPivot and a server with a copy of the OLTP database(s). Building cubes is labour intensive and doesn't always give the user what they need. This is where the BI Semantic Model (BISM) comes in. I gather it's a layer of metadata you define that can combine multiple data sources (and types of data source) into a clear 'interface' that users can work with. It comes with a new query language called DAX. SSAS cubes are unlikely to go away overnight because, with their pre-calculated results, they are still the most efficient way to work with really big data sets. A few other random titbits that came up: Reporting Services is going to get some good new stuff in Denali. Keep an eye on www.projectbotticelli.com for the slides. You can also view last year's seminar sessions which covered a lot of the same ground as far as the overall strategy is concerned. They plan to add more material as Denali's features are publicly exposed. Check out the PASS keynote address for a showing of Yahoo's SQL BI servers. Apparently they wheeled the rack out on stage still plugged in and running! Check out the Excel 2010 Data Mining Add-Ins. 32 bit only at present but 64 bit is on the way. There are lots of data sets, many of them free, at the Windows Azure Marketplace Data Market (where you can also get ESRI shape files). If you haven't already seen it, have a look at the Silverlight Pivot Viewer (http://weblogs.asp.net/scottgu/archive/2010/06/29/silverlight-pivotviewer-now-available.aspx). The Bing Maps Data Connector is worth a look if you're into spatial stuff (http://www.bing.com/community/site_blogs/b/maps/archive/2010/07/13/data-connector-sql-server-2008-spatial-amp-bing-maps.aspx).

• AJI Report #19 | Scott K Davis and his son Tommy on Gamification and Programming for Kids

  - by Jeff Julian

  We are very excited about this show. John and Jeff sat down with Scott Davis and his son Tommy to talk about Gamification and Programming for Kids. Tommy is nine years old and the Iowa Code Camp was his second time presenting. Scott and Tommy introduce a package called Scratch that was developed by MIT to teach kids about logic and interacting with programming using sprites. Tommy's favorite experience with programming right now is Lego Mindstorms because of the interaction with the Legos and the development. Most adults when they get started with development also got started with interacting more with the physical machines. The next generation is given amazing tools, but the tools tend to be sealed and the physical interaction is not there. With some of these alternative hobby platforms like Legos, Arduino, and .NET Micro Framework, kids can write some amazing application and see their code work with physical movement and interaction with devices and sensors. In the second half of this podcast, Scott talks about how companies can us Gamification to prompt employees to interact with software and processes in the organization. We see gamification throughout the consumer space and you need to do is open up the majority of the apps on our phones or tablets and there is some interaction point to give the user a reward for using the tool. Scott gets into his product Qonqr which is described as the board game Risk and Foursquare together. Scott gets into the different mindsets of gamers (Bartle Index) and how you can use these mindsets to get the most out of your team through gamification techniques.

• MonoDroid Article in Visual Studio Magazine

  - by Wallym

  The February edition of Visual Studio magazine is now online.  In it, my article regarding MonoDroid, the implementation of C# and .NET for Android devices, is online.  I can't thank Michael Desmond enough for the opportunity.  Its fitting now that Android is the most popular smartphone platform.  This article is available online at: Intro to MonoDroid Part 1. Intro to MonoDroid Part 2. Along with the article, check out this short video that I did regarding MonoDroid on the Mac. The article(s) were written based on MonoDroid Preview 9.1, so there are a few updates necessary, but I think this gets the basics out.  I hope you enjoy the article(s). And yes, we're still working on our book on MonoDroid.  I've got a great author group and am excited about the book. If you get a chance, come to AnDevCon in San Francisco in March.  I'll be presenting on MonoDroid there.

• Validating SSL clients using a list of authorised certificates instead of a Certificate Authority

  - by Gavin Brown

  Is it possible to configure Apache (or any other SSL-aware server) to only accept connections from clients presenting a certificate from a pre-defined list? These certificates may be signed by any CA (and may be self-signed). A while back I tried to get client certificate validation working in the EPP system of the domain registry I work for. The EPP protocol spec mandates use of "mutual strong client-server authentication". In practice, this means that both the client and the server must validate the certificate of the other peer in the session. We created a private certificate authority and asked registrars to submit CSRs, which we then signed. This seemed to us to be the simplest solution, but many of our registrars objected: they were used to obtaining a client certificate from a CA, and submitting that certificate to the registry. So we had to scrap the system. I have been trying to find a way of implementing this system in our server, which is based on the mod_epp module for Apache.

• Slides and links for Looking at the Clouds through Dirty Windows :-)

  - by Eric Nelson

  Tomorrow (Friday 23/4/2010) I am delivering a session at the Cloud Grid Exchange in London at SkillsMatter (A top training company and superb supporter of development communities). To be perfectly honest – I’m more interested in attending than presenting as the sessions and speaker line up look great. But in the middle of all that I will be doing the following (rather cheekily named) session: Looking at the Clouds through dirty Windows Many developers assume that the Microsoft Windows Azure Platform for Cloud Computing is only relevant if you develop solutions using Microsoft Visual Studio and the .NET Framework. The reality is somewhat different. In the same way that developers can build great applications on Windows Server using a variety of programming languages, developers can do the same for Azure. Java, Tomcat, PHP, Ruby, Python, MySQL and more all work great on Azure. In this session we will take a lap around the services offered by the Azure PaaS and demonstrate just how easy it is to build and deploy applications built in .NET and other technologies. The session will be a mix of slides and demos – currently I plan to demo .NET and Ruby on Rails running on Azure – but I may flex that depending on how the morning sessions go and who turns up.

What does this really mean for CRM software? Is it Dead or Alive? Listen to Mark’s view from Oracle and its customers.                  Location- Westbourne 2, Level –1. Also stop by the Oracle booth at the demogrounds.  The event looks promising with some great content from the Gartner analysts and from what the Gartner folks just told me, the event is oversold. And the weather in London town? As expected…slight showers on Monday with a high of 49 degrees F and partly cloudy on Tuesday, with a high of 50 degrees F.

• Test Driven Development (TDD) in Visual Studio 2010- Microsoft Mondays

  - by Hosam Kamel

  November 14th , I will be presenting at Microsoft Mondays a session about Test Driven Development (TDD) in Visual Studio 2010 . Microsoft Mondays is program consisting of a series of Webcasts showcasing various Microsoft products and technologies. Each Monday we discuss a particular topic pertaining to development, infrastructure, Office tools, ERP, client/server operating systems etc. The webcast will be broadcast via Lync and can viewed from a web client. The idea behind the “Microsoft Mondays” program is to help you become more proficient in the products and technologies that you use and help you utilize their full potential.   Test Driven Development in Visual Studio 2010 Level – 300 (  Intermediate – Advanced ) Test Driven Development (TDD), also frequently referred to as Test Driven Design, is a development methodology where developers create software by first writing a unit test, then writing the actual system code to make the unit test pass.  The unit test can be viewed as a small specification around how the system should behave; writing it first helps the developer to focus on only writing enough code to make the test pass, thereby helping ensure a tight, lightweight system which is specifically focused meeting on the documented requirements. TDD follows a cadence of “Red, Green, Refactor.” Red refers to the visual display of a failing test – the test you write first will not pass because you have not yet written any code for it. Green refers to the step of writing just enough code in your system to make your unit test pass – your test runner’s UI will now show that test passing with a green icon. Refactor refers to the step of refactoring your code so it is tighter, cleaner, and more flexible. This cycle is repeated constantly throughout a TDD developer’s workday. Date:   November 14, 2011 Time:  10:00 a.m. – 11:00 a.m. (GMT+3)  http://www.eventbrite.com/event/2437620990/efbnen?ebtv=F   See you there! Hosam Kamel Originally posted at

• just curious if anybody every tried this- hyper-v r2

  - by tony roth

  I have a server that san boots that I want to p2v. I have many options disk2vhd, scvmm etc but I was thinking about cloning the lun (flexclone, netapp) presenting it to my hyper-v r2 server. Within the hv manager do a create new disk then have it copy the cloned lun to a vhd file. Then do the bcdedit\bootsect stuff to it. Should work right? I'm also curious if anybodys booting vhd's that are on bootable luns? I've booted native vhd's just fine was just curious about the running them off a bootable lun. I think that this has quite a few advantages like instant p2v etc.. any thoughts on this? hmm dang as I was typing this I realized that I should not use the hv manager new disk copy routine, I should just disk2vhd the mounted lun. This has advantages in that it should be a lot faster!! thanks

• Windows Update can't install Windows Vista SP1

  - by Harry Johnston

  If you install Windows Vista RTM and run Windows Update, many updates are offered and will successfully install. Once all other updates are installed, Windows Vista service pack 1 is offered. When you attempt to install Windows Vista service pack 1, the service pack installation wizard appears, presenting the license agreement and so on. However, shortly after the installation starts the wizard disappears. Windows Update says that the update was installed successfully. However, service pack 1 is not in fact installed, and will be detected as needed again on the next update check. Repeat ad nauseum. On checking the Windows Update log, error 0x80190194 appears near the beginning of an update check, associated with the URL http://update.microsoft.com/vista/windowsupdate/redir/vistawuredir.cab. Why won't service pack 1 install properly and how do I fix it?

• Worldwide Web Camps

  - by ScottGu

  Over the next few weeks Microsoft is sponsoring a number of free Web Camp events around the world.  These provide a great way to learn about ASP.NET 4, ASP.NET MVC 2, and Visual Studio 2010. The Web Camps are two day events.  The camps aren’t conferences where you sit quietly for hours and people talk at you – they are intended to be interactive.  The first day is focused on learning through presentations that are heavy on coding demos.  The second day is focused on you building real applications using what you’ve learned.  The second day includes hands-on labs, and you’ll join small development teams with other attendees and work on a project together. We’ve got some great speakers lined up for the events – including Scott Hanselman, James Senior, Jon Galloway, Rachel Appel, Dan Wahlin, Christian Wenz and more.  I’ll also be presenting at one of the camps. Below is the schedule of the remaining events (the sold-out Toronto camp was a few days ago): Moscow May 19-19 Beijing May 21-22 Shanghai May 24-25 Mountain View May 27-28 Sydney May 28-29 Singapore June 04-05 London June 04-05 Munich June 07-08 Chicago June 11-12 Redmond, WA June 18-19 New York June 25-26 Many locations are sold out already but we still have some seats left in a few of them.  Registration and attendance to all of the events is completely free.  You can register to attend at www.webcamps.ms. Hope this helps, Scott

• LobsterPot Solutions in the USA

  - by Rob Farley

  We’re expanding! I’m thrilled to announce that Microsoft Gold Partner LobsterPot Solutions has started another branch appointing the amazing Ted Krueger (5-time SQL MVP awardee) as the US lead. Ted is well-known in the SQL Server world, having written books on indexing, consulting and on being a DBA (not to mention contributing chapters to both MVP Deep Dives books). He is an expert on replication and high availability, and strong in the Business Intelligence space – vast experience which is both broad and deep. Ted is based in the south east corner of Wisconsin, just north of Chicago. He has been a consultant for eons and has helped many clients with their projects and problems, taking the role as both technical lead and consulting lead. He is also tireless in supporting and developing the SQL Server community, presenting at conferences across America, and helping people through his blog, Twitter and more. Despite all this – it’s neither his technical excellence with SQL Server nor his consulting skill that made me want him to lead LobsterPot’s US venture. I wanted Ted because of his values. In the time I’ve known Ted, I’ve found his integrity to be excellent, and found him to be morally beyond reproach. This is the biggest priority I have when finding people to represent the LobsterPot brand. I have no qualms in recommending Ted’s character or work ethic. It’s not just my thoughts on him – all my trusted friends that know Ted agree about this. So last week, LobsterPot Solutions LLC was formed in the United States, and in a couple of weeks, we will be open for business! LobsterPot Solutions can be contacted via email at [email protected], on the web at either www.lobsterpot.com.au or www.lobsterpotsolutions.com, and on Twitter as @lobsterpot_au and @lobsterpot_us. Ted Kruger blogs at LessThanDot, and can also be found on Twitter and LinkedIn. This post is cross-posted from http://lobsterpotsolutions.com/lobsterpot-solutions-in-the-usa
