  • How did I get here? My route to Android, iPhone, Windows Phone 7, and interest in Mobile Devices

    - by Wallym
    I get asked all the time how/why I got interested in mobile and jumped on this fairly early.  I tend to give half answers because it wasn't just one thing that took me to mobile, but a whole host of separate ivents culminating in a specific event where I wasdoing market research in May/June 2008.  Let me throw out the events and the facts about me: I tend to like new, different, cool stuff.  I jumped on .NET early on.  I jumped on Ajax early on.  I don't jump on every new technology that comes down the road, I'm probably the only person on the planet that doesn't "get" MVC, though I acknowledge that a lot of people do and it solves a number of problems in the default settings of ASP.NET WebForms. I remember buying an early Windows CE device. It was interesting, but dang, this stylus thing sucks. After I lost my third stylus, i just gave up.  I got my first mobile phone in early 1999.  Reception was crappy, but I could see the value in being mobile. In 1999, I worked on a manufacturing systems project.  One piece of the projects was a set of handheld devices on the shop floor.  While the UI was a crappy DOS based, yes I said DOS as in Disk Operating System Version 6.22, I could see that the wireless world was a direction I wanted to be in. In 2000, Microsoft released the first public alpha of .NET.  Very cool stuff indeed.  One piece of the puzzle was a set of mobile controls for ASP.NET.  I build numerous test apps as well as mobile version using these mobile controls.  Now, the mobile UIs of the time were based on WML, which was crap. I could real all the analysis of mobile and read all about growth rates.  Now, you have to realize that growth rates can be impressive when dealing with small numbers, but I knew it was a comer. In our first book, I got talked out of mobile because of the line from the publisher "Wally, mobile doesn't sell." Blackberry was the dominant device of the mid 2000s.  Its users were referred to as "Crackberry addicts."  Unfortunately, the mobile development experience for native apps was crap and the web experience was fairly rough as well, but if they could get the ecosystem started, other phones and better blackberryies would come out.  I finally jumped into using a blackberry. Sometime around 2006, I heard "Wally, mobile doesn't sell" again.  Now, anyone that knows me knows that someone saying something like this to me means I'll keep trying it. The phones of the mid 2000s were moving to be more graphical, but there were too many that had this idea that they had to use a stylus.  Stylus suck.  They get lost too easily. I worked on a project in 2007 and 2008 for a startup trying to answer the question of "What is there to do where I am at?"  For some reason, they wanted to be tied to PCs.  As it became obvious that they were having problems, their investor asked us to do some market research and to figure out what the marketplace did want.  One of the important things that I figured out was the we lived in a mobile world and if you had a mobile app, it need to be on a mobile device, not tied to a desktop/laptop/netbook device.  If there was any single event, this was it - I was doing some market research and sat and talked to people in a bar/restaurant in Atlanta called "The Grove" on Lavista.  The consensus of the people that I talked to was that they wanted their data where ever they were at, laptop, pc, mobile, whereever. In 2007, Apple released the iPhone.  Wow, what an impressive device, even with all the problems of a 1st generation device.  I bought an iPod Touch 1st generation to understand touch better, one of the best decisions I ever made. I decided in late 2008, to make a move into cloud, for a number of reasons.  I was working on an example app.  In April, 2009, one of my friends at Microsoft said "don't mention my name with this, but you need an iPhone front end for this app."  How do you get on the iPhone.  Well, there are a number of ways including: ObjectiveC.  Its hard to teach an old dog new tricks, and this dog knows .NET, not ObjectiveC. HTML, web, javascript optimized interface.  yeah, this is possible. PhoneGap.  Now, this is interesting, take an html interface and get it to run on the iPhone, Android, Blackberry, and other platforms.  I thought that this way made the most sense for me until......... MonoTouch.  In May/June 2009, Novell announced a way for .NET/c# developers to write apps for the iPhone.  This is the way that made the most sense to me. Titanium by Appcelerator.  This is similar in concept to PhoneGap.  I haven't played with this much but do want to learn more about it. In July, 2009, I emailed one of my contacts at Wrox to see if they would be interested in a short MonoTouch ebook in their Wrox Blox format.  I fully expected another  response along the lines of "Wally, mobile doesn't sell."  The response I got was "Wally, iPhone is H O T, get started immediately, can you have this to me before Labor Day."  Not quite the response I expected.  Thankfully, we didn't make the Labor Day, first draft date. I kept pushing back because I had a feeling that things were not going to be quite as polished and feature rich as necessary.  After all, Novell doesn't have the resouces of Microsoft's developer division. The ebook shipped on November 30, 2009. On about December, 15, 2009, my editor emailed and said "Your ebook is selling really well, lets do a full book and it by March 1 so get started."  Thankfully, guys like Craig Dunn and Chris Hardy were interested along with Martin and Ror joinged us later on. I bought my wife an iPhone 3Gs in early 2010 to go along with all my iPod Touch devices. I tried to pretend in 2010 that I wasn't that interested in mobile and still had interest in the desktop technologies.  I love the technologies and continue to use them today, but that isn't where my interest is right now.  I'm just about all mobile all the time with my energies.  Our book shipped in the beginning of July, 2010 right in the middle of the Apple FUD.I've been looking at Mobile Web as a way around the AppStores and Apple FUD problems of 2010. With all the Apple self FUD, we became interested in Android.I went up to Dino Esposito at DevConnections in Las Vegas at introduced myself. I've always tried to keep up with what Dino has been doing. I was shocked, he wanted to meet me.  We must have talked for 1.5 hours. It was way more time than I deserved. If you get a chance, go and introduce yourself to Dino. He's a great guy. Microsoft released Windows Phone 7 in the Fall of 2010.  I'm not doing development on that platform at this time.  I think they have a very interesting user interface.  The devices are being positively reviewed.  For my purposes, the devices are limited at this point in time.  We'll see what 2011 brings as far as updates to the operating system.  I need multitasking/background processing and html5 in the browser. Add that as well as acceptance in the marketplace and I'll be more interested in the device. Obviosuly, I'm now working on a MonoDroid book . I own Android and iPhone/iOS devices.  I am currently working on some startup ideas and am exploring as much in that area as I can. For 2011, I'm planning on speaking at Android Developer's Conference (AnDevCon) and Mobile Connections.  I'm really excited about this. I have a couple of magazine articles coming out in 2011 on Android and iPhone development with the Mono technologies.is Mono "The Answer"? What's "The Question?" I think it will work for me.  It might work for you, it might not.  it depends on your situation.  Its the current horse that I am riding. I might find a better horse tomorrow. So, that's how I got here.  I'm in love with mobile.  Mobile native apps on the device as well as mobile web.  I'm into all this cool stuff.  Where are you at?

  • Introducing the BizTalk Maturity Assessment

  • How is IntelliJ better than Eclipse?

    - by NickC
    I know there have been questions like What is your favorite editor/IDE?, but none of them have answered this question: Why spend the money on IntelliJ when Eclipse is free? I'm personally a big IntelliJ fan, but I haven't really tried Eclipse. I've used IntelliJ for projects that were Java, JSP, HTML/CSS, Javascript, PHP, and Actionscript, and the latest version, 9, has been excellent for all of them. Many coworkers in the past have told me that they believe Eclipse to be "pretty much the same" as IntelliJ, but, to counter that point, I've occasionally sat behind a developer using Eclipse who's seemed comparably inefficient (to accomplish roughly the same task), and I haven't experienced this with IntelliJ. They may be on par feature-by-feature but features can be ruined by a poor user experience, and I wonder if it's possible that IntelliJ is easier to pick up and discover time-saving features. For users who are already familiar with Eclipse, on top of the real cost of IntelliJ, there is also the cost of time spent learning the new app. Eclipse gets a lot of users who simply don't want to spend $250 on an IDE. If IntelliJ really could help my team be more productive, how could I sell it to them? For those users who've tried both, I'd be very interested in specific pros or cons either way.

  • C# via Java: Introduction

After all, the design of C# was based on Java 1.2, and both languages have continued to evolve since then, incorporating modern software engineering concepts and requirements. Exploring the differences and similarities between the two will (hopefully) give us a deeper understanding into why .NET is implemented the way it is, the trade-offs involved, and what choices were made when new features were designed and added to the language and framework. Among others, I'll be looking at differences in: Primitives Operators Generics Exceptions Accessibility Collections Delegates and inner classes Concurrency In my next post, I'll start off by looking at the type primitives available in each language, and how Java and C# actually incorporate two different concepts of primitive types in their fundamental language design and use. I'm also thinking of looking at the inner details of Java and the JVM in my blogs, as well as C# and the CLR. If you've got any comments or thoughts on this, please let me know.

  • SQL SERVER – 2000 – DBCC SQLPERF(waitstats) – Wait Type – Day 24 of 28

    - by pinaldave
    I have received many comments, email, suggestions and motivations for my current series of wait types and wait statistics. One of the questions which I keep on receiving almost every other day is whether all of the discussions I have presented so far are also applicable to SQL Server 2000. Additionally, I receive another question asking me if wait statistics matters in SQL Server 2000. If it is, then the asker wants to know how to measure wait types for SQL Server 2000. In SQL Server, you can run the following command to get a list of all the wait types: DBCC SQLPERF(waitstats) The query above will work in SQL Server 2005/2008/R2  because of backup compatibility. As you might have noticed, I have been discussing everything keeping SQL Server 2005+ in mind, but I have given little consideration on SQL Server 2000. However, I am pretty sure that most of the suggestions I have provided are applicable to SQL Server 2000. The wait types I have been discussing mostly exist in SQL Server 2000 as well. But the difference of the 2000 version is that it gets late recent releases, but it is worth it. Wait types are very essential to measure performance bottleneck. Because of this, I do not have to state that I am big fan of them just so I could identify performance bottleneck. Please read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussion of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

  • Anonymous Access and Sharepoint Web Services

    - by Stacy Vicknair
    A month or so ago I was working on a feature for a project that required a level of anonymity on the Sharepoint site in order to function. At the same time I was also working on another feature that required access to the Sharepoint search.asmx web service. I found out, the hard way, that the Sharepoint Web Services do not operate in an expected way while the IIS site is under anonymous access. Even though these web services expect requests with certain permissions (in theory) they never attempt to request those credentials when the web service is contacted. As a result the services return a 401 Unauthorized response. The fix for my situation was to restrict anonymous access to the area that needed it (in this case the control in question had support for being used in an ASP.NET app that I could throw in a virtual directory). After that I removed anonymous access from IIS for the site itself and the QueryService requests were working once more. Here’s a related article with a bit more depth about a similar experience: http://chrisdomino.com/Blog/Post/401-Reasons-Why-SharePoint-Web-Services-Don-t-Work-Anonymously?Length=4 Technorati Tags: Sharepoint,QueryService,WSS,IIS,Anonymous Access

  • 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

  • Intel graphics driver installer, now the CPU fan is rarely quiet

    - by Space monkey
    I have an Optimus chipset: Intel HD 4000 (i7-3635QM CPU) Geforce 640m I don't care about the NVIDIA card, so I didn't try to install any proprietary drivers for it. So: I was having a choppy+high CPU experience with gnome-shell on Ubuntu 14.04. Only happened when I tried moving a window around quickly. I used the Intel graphics installer hoping that it will fix the problem. It did fix the problem, now there is no choppyness or high CPU when I move windows around. However, there is a new problem now: The fan is rarely quiet, doing barely anything at all will cause the fan to go into loud mode quickly. That happens despite the CPU usage being at just around 4%. This wasn't the case before installing Intel drivers. It would normally only do that if, for example, I'm installing packages or doing something that puts some stress on the CPU. I set all CPU cores to "powersave" using cpufreq-set, but nothing changed. Also on Windows, the fans are really quiet when I'm in powersave mode. I believe they completely shut off for most of the time. I remember the installer giving me a report at the end as to which packages it installed. Unfortunately, I didn't save the report and I don't know where it would have saved it if it did. Any ideas or similar experiences?

  • Surface RT: To Be Or Not To Be (Part 1)

    - by smehaffie
    So the Surface RT has been out for 9 months and Microsoft just declared a $900 million dollar write-down. So how did this happen and what does it mean for Microsoft’s efforts to break into the tablet market? I have been thinking a lot about most of the information below since the Surface product line was released. If you are looking for a “Microsoft Is Dead” story, then don’t read any further. But if you want an honest look at what I think led Microsoft to this point and what I think can be done to make Surface RT devices better, then please continue reading. What Led Microsoft To The $900 Million Write-Down Surface Unveiling:Microsoft totally missed the boat when they unveiled the Surface product line on June 18th, 2012. Microsoft should’ve been ready to post the specifications of both devices that night. Microsoft should’ve had a site up and running right after the event so people could pre-order the devices. This would have given them a good idea what the interest was in each device.  They could also have used this data to make a better estimate for the number of units to to have available for the launch and beyond.  They also lost out on taking advantage of the excitement generated by the Surface RT and Surface Pro announcement. They could have thrown in a free touch keyboard to anyone who pre-ordered. The advertising should have started right after the announcement and gotten bigger as launch day approached. Push for as many pre-order as possible and build excitement for the launch. Actual Launch (Surface RT): By this time all excitement was gone from the initial announcement, except for the Micorsoft faithful. Microsoft should have been ready to sell the Surface in as many markets as possible at launch. The limited market release was a real letdown for a lot of people.  A limited release right after the initial announce is understandable, but not at the official launch of the product. Microsoft overpriced the device and now they are lowering it to what it should have been to start with. The $349 price is within the range I suggested it should be at before pricing was announced. (Surface Tablets: The Price Must Be Right). Limited ordering options online was also a killer. User should have been able to buy the base unit of each device and then add on whatever keyboard they wanted to (this applies more to the Surface Pro).  There should have also been a place where users could order any additional add-ins that they wanted to buy (covers, extra power supplies, etc.) Marketing was better and the dancing “Click In” commercial was cool, but the ads comparing the iPad with Siri should have been on the air from day one of the announcement (or at least the launch).  Consumers want to know why you tablet is better, not just that is has a clickable keyboard and built-in kickstand. They could have also compared it to some of the other mid-range tablets if they had not overprices it to begin with. Stock Applications (Mail, People, Calendar, Music, Video, Reader and IE): This is where Microsoft really blew it. They had all the time in the world to make these applications the best of breed and instead we got applications that seemed thrown together.  Some updates have made these application better, but they are all still lacking in features that should have been there from day one. This did not help to enhance a new users experience any. ** I will admit that the applications that were data driven were first class citizen’s and that makes it even more perplexing why MS could knock it out of the park with the Weather, Travel, Finance, Bing, etc.) and fail so miserably on the core applications users would use the most on a tablet. Desktop on Tablet: The desktop just is so out of place on the tablet  I understand it was needed for Office but think it would have been better to not have the desktop in Windows RT, but instead open up the Office applications in full screen mode, in a desktop shell (same goes for  IE11).That way the user wouldn’t realize they are leaving Metro and going to the desktop. The other option would have been to just not include Office on Windows RT devices. Instead they could have made awesome Widows Store Apps for Word, Excel, OneNote and PowerPoint. In addition, they could have made the stock Mail, People, and Calendar applications contain all the functions that Outlook gives desktop users. Having some of the settings in desktop mode and others under “Change PC Settings” made Windows RT seemed unfinished and rushed to market. What Can Be Done To Make Windows RT Based Tablets Better (At least in my opinion) Either eliminate the desktop all together from Windows RT or at least make the user experience better by hiding the fact the user is running Office/IE in the desktop. Personally I ‘d like them to totally get rid of it and just make awesome Windows Store Application version of Word, Excel PowerPoint & OneNote.  This might also make the OS smaller and give the user more available disk space. I doubt there will ever be a Windows Store App versions of Office, but I still think it is a good idea. Make is so users can easily direct their documents, picture, videos and music to their extra storage and can access these files from the standard libraries.  A user should not have to create a VM on their microSD card or create symbolic links to get this to work properly. Most consumers would not be able to do this. Then users get frustrated when they run out or room on their main storage because nothing is automatically save to their microSD card when saved to libraries.  This is a major bug that needs to be fixed, otherwise Microsoft’s selling point of having a microSD slot is worthless. Allows users to uninstall and re-install any of the Office product that come with the Surface. That way people can free up storage space by uninstalling the Office applications they do not need. Everyone’s needs are different, so make the options flexible. Don’t take up storage space for applications the user will not use. Make the Core applications the “Cream of the Crop” Windows App Store applications. The should set the bar for all other Store applications. Improve performance as much as possible, if it seems to be sluggish on a tablet consumer will not buy it. They need to price the next line of Surface product very aggressive to undercut not only iPad but also Android low end tablets (Nook, Kindle Fire, and Nexus, etc.) Give developers incentives to write quality applications for the devices. Don’t reward developers for cranking out cookie cutter, low quality applications. I’d even suggest Microsoft consider implementing some new store certification guideline to stop these type of applications being published. Allow users to easily move the recover disk “partition between their microSD card and main storage. My Predictions for the Surface RT and Windows RT I honestly think even with all the missteps MS has made since the announcement  about the Surface product line, that they are on the right path. I was excited the Surface tablets when they were announced, and I still am. The truth be told, Windows 8 on a tablet (aka: Windows RT) is better than both iOS and Android. My nephew who is an Apple fan boy told me after he saw and used Windows 8 (he got the beta running on his iPad), that Windows 8 kicked Apples butt as a tablet OS. So there is hope for all Windows RT based tablets. I agree with my nephew and that is why whenever anyone asks me about my Surface, I love showing it off and recommend it. The 6 keys to gaining market share in the tablet market are; Aggressive pricing by both Microsoft and their OEM’s Good quality devices put out by Microsoft and their OEM’s (there are some out there, but not enough) Marketing, Marketing, Marketing from both Microsoft and their OEM’s (Need more ads showing why windows based tablets are better than iPads and Android tablets) Getting Widows tablets in retails stores all over, and giving sales people incentive to sell them. Consumers like to try electronics out before they buy them, and most will listen to what the sales person suggest. Microsoft needs sales people in retail stores directing people to buy windows based tablets over iPads and Android tablets. I think the Microsoft Stores within Best Buy is a good start, but they also need to get prominent displays in Walmart, Target, etc.. Release a smaller form factor Surface, Hopefully the 8”-10” next generation Surface is not a rumor. Make “Surface” the brand name for all Microsoft tablets and hybrid devices that they come out with. They cannot change the name with each new release.  Make Surface synonymous with quality, the same way that iPad  is for Apple. Well, that is my 2 cents on the subject. Let me know your thoughts by leaving a comment below. Soon to follow will be my thought on the Surface Pro, so keep an eye out for it. var addthis_pub="smehaffie"; var addthis_options="email, print, digg, slashdot, delicious, twitter, live, myspace, facebook, google, stumbleupon, newsvine";

  • Some SharePoint NDA Information

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Many years ago, at the last to last to last MVP summit, Microsoft was kind enough to share with us what they were thinking wayyyyyyyyyyyy ahead! I specially remember John Durant talking about the specific enhancements planned for SharePoint 2010 development experience. If you haven’t seen John Durant talking on stage, the guy has more enthusiasm than tiger woods in Amsterdam! The energy of his presentations is simply amazing. So, I pulled out my phone, and I snapped a picture! And, I emailed that picture to everyone in the MVP land, and Microsoft land, saying “We have evidence”, i.e. here are the promises that were made, and dammit we’ll see by the time you release SP2010 how many of these do you actually release. Here is the picture ladies and gentlemen -     It’s a good karate chop action shot isn’t it? Of course, we were all immediately warned not to share any of this seriously strictly NDA information at the time. Well, now that the information is out in the world, I can finally share now, this small tidbit of how far ahead Microsoft is thinking in their plans. Frankly, I wouldn’t be surprised, if today that they have a very clear idea what SharePoint vNext will be all about, or should I say vNextvNext? Have fun! Comment on the article ....

  • CIC 2010 - Ghost Stories and Model Based Design

    - by warren.baird
    I was lucky enough to attend the collaboration and interoperability congress recently. The location was very beautiful and interesting, it was held in the mountains about two hours outside Denver, at the Stanley hotel, famous both for inspiring Steven King's novel "The Shining" and for attracting a lot of attention from the "Ghost Hunters" TV show. My visit was prosaic - I didn't get to experience the ghosts the locals promised - but interesting, with some very informative sessions. I noticed one main theme - a lot of people were talking about Model Based Design (MBD), which is moving design and manufacturing away from 2d drawings and towards 3d models. 2d has some pretty deep roots in industrial manufacturing and there have been a lot of challenges encountered in making the leap to 3d. One of the challenges discussed in several sessions was how to get model information out to the non-engineers in the company, which is a topic near and dear to my heart. In the 2D space, people without access to CAD software (for example, people assembling a product on the shop floor) can be given printouts of the design - it's not particularly efficient, and it definitely isn't very green, but it tends to work. There's no direct equivalent in the 3D space. One of the ways that AutoVue is used in industrial manufacturing is to provide non-CAD users with an easy to use, interactive 3D view of their products - in some cases it's directly used by people on the shop floor, but in cases where paper is really ingrained in the process, AutoVue can be used by a technical publications person to create illustrative 2D views that can be printed that show all of the details necessary to complete the work. Are you making the move to model based design? Is AutoVue helping you with your challenges? Let us know in the comments below.

  • SQL SERVER – Weekly Series – Memory Lane – #003

    - by pinaldave
    Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 This was the first year of my blogging and lots of new things I was learning as I go. I was indeed an infant in blogging a few years ago. However, as time passed by I have learned a lot. This year was year of experiments and new learning. 2007 Working as a full time DBA I often encoutered various errors and I started to learn how to avoid those error and document the same. ERROR Msg 5174 Each file size must be greater than or equal to 512 KB Whenever I see this error I wonder why someone is trying to attempt a database which is extremely small. Anyway, it does not matter what I think I keep on seeing this error often in industries. Anyway the solution of the error is equally interesting – just created larger database. Dilbert Humor This was very first encounter with database humor and I started to love it. It does not matter how many time we read this cartoon it does not get old. Generate Script with Data from Database – Database Publishing Wizard Generating schema script with data is one of the most frequently performed tasks among SQL Server Data Professionals. There are many ways to do the same. In the above article I demonstrated that how we can use the Database Publishing Wizard to accomplish the same. It was new to me at that time but I have not seen much of the adoption of the same still in the industry. Here is one of my videos where I demonstrate how we can generate data with schema. 2008 Delete Backup History – Cleanup Backup History Deleting backup history is important too but should be done carefully. If this is not carried out at regular interval there is good chance that MSDB will be filled up with all the old history. Every organization is different. Some would like to keep the history for 30 days and some for a year but there should be some limit. One should regularly archive the database backup history. South Asia MVP Open Days 2008 This was my very first year Microsoft MVP. I had Indeed big blast at the event and the fun was incredible. After this event I have attended many different MVP events but the fun and learning this particular event presented was amazing and just like me many others are not able to forget the same. Here are other links related to the event: South Asia MVP Open Day 2008 – Goa South Asia MVP Open Day 2008 – Goa – Day 1 South Asia MVP Open Day 2008 – Goa – Day 2 South Asia MVP Open Day 2008 – Goa – Day 3 2009 Enable or Disable Constraint  This is very simple script but I personally keep on forgetting it so I had blogged it. Till today, I keep on referencing this again and again as sometime a very little thing is hard to remember. Policy Based Management – Create, Evaluate and Fix Policies This article will cover the most spectacular feature of SQL 2008 – Policy-based management and how the configuration of SQL Server with policy-based management architecture can make a powerful difference. Policy based management is loaded with several advantages. It can help you implement various policies for reliable configuration of the system. It also provides additional administrative assistance to DBAs and helps them effortlessly manage various tasks of SQL Server across the enterprise. SQLPASS 2009 – My Very First SQPASS Experience Just Brilliant! I never had an experience such a thing in my life. SQL SQL and SQL – all around SQL! I am listing my own reasons here in order of importance to me. Networking with SQL fellows and experts Putting face to the name or avatar Learning and improving my SQL skills Understanding the structure of the largest SQL Server Professional Association Attending my favorite training sessions Since last time I have never missed a single time this event. This event is my favorite event and something keeps me going. Here are additional post related SQLPASS 2009. SQL PASS Summit, Seattle 2009 – Day 1 SQL PASS Summit, Seattle 2009 – Day 2 SQL PASS Summit, Seattle 2009 – Day 3 SQL PASS Summit, Seattle 2009 – Day 4 2010 Get All the Information of Database using sys.databases Even though we believe that we know everything about our database, we do not know a lot of things about our database. This little script enables us to know so many details about databases which we may not be familiar with. Run this on your server today and see how much you know your database. Reducing CXPACKET Wait Stats for High Transactional Database While engaging in a performance tuning consultation for a client, a situation occurred where they were facing a lot of CXPACKET Waits Stats. The client asked me if I could help them reduce this huge number of wait stats. I usually receive this kind of request from other client as well, but the important thing to understand is whether this question has any merits or benefits, or not. I discusses the same in this article – a bit long but insightful for sure. Error related to Database in Use There are so many database management operations in SQL Server which requires exclusive access to the database and it is not always possible to get it. When any database is online in SQL Server it either applications or system thread often accesses them. This means database can’t have exclusive access and the operations which required this access throws an error. There is very easy method to overcome this minor issue – a single line script can give you exclusive access to the database. Difference between DATETIME and DATETIME2 Developers have found the root reason of the problem when dealing with Date Functions – when data time values are converted (implicit or explicit) between different data types, which would lose some precision, so the result cannot match each other as expected. In this blog post I go over very interesting details and difference between DATETIME and DATETIME2 History of SQL Server Database Encryption I recently met Michael Coles and Rodeney Landrum the author of one of the kind book Expert SQL Server 2008 Encryption at SQLPASS in Seattle. During the conversation we ended up how Microsoft is evolving encryption technology. The same discussion lead to talking about history of encryption tools in SQL Server. Michale pointed me to page 18 of his book of encryption. He explicitly gave me permission to re-produce relevant part of history from his book. 2011 Functions FIRST_VALUE and LAST_VALUE with OVER clause and ORDER BY Some time an interesting feature and smart audience make a total difference in places. From last two days, I have been writing on SQL Server 2012 feature FIRST_VALUE and LAST_VALUE. I created a puzzle which was very interesting and got many people attempt to resolve it. It was based on following two articles: Introduction to FIRST_VALUE and LAST_VALUE Introduction to FIRST_VALUE and LAST_VALUE with OVER clause I even provided the hint about how one can solve this problem. The best part was many people solved the problem without using hints! Try your luck!  A Real Story of Book Getting ‘Out of Stock’ to A 25% Discount Story Available This is a great problem and everybody would love to have it. We had it and we loved it. Our book got out of stock in 48 hours of releasing and stocks were empty. We faced many issues and learned many valuable lessons. Some we were able to avoid in the future and some we are still facing it as those problems have no solutions. However, since that day – our books never gone out of stock. This inspiring learning story for us and I am confident that you will love to read it as well. Introduction to LEAD and LAG – Analytic Functions Introduced in SQL Server 2012 SQL Server 2012 introduces new analytical function LEAD() and LAG(). This function accesses data from a subsequent row (for lead) and previous row (for lag) in the same result set without the use of a self-join . It will be very difficult to explain this in words so I will attempt small example to explain you this function. I had a fantastic time writing this blog post and I am very confident when you read it, you will like the same.

  • Making a Case For The Command Line

    - by Jesse Taber
    Originally posted on: http://geekswithblogs.net/GruffCode/archive/2013/06/30/making-a-case-for-the-command-line.aspxI have had an idea percolating in the back of my mind for over a year now that I’ve just recently started to implement. This idea relates to building out “internal tools” to ease the maintenance and on-going support of a software system. The system that I currently work on is (mostly) web-based, so we traditionally we have built these internal tools in the form of pages within the app that are only accessible by our developers and support personnel. These pages allow us to perform tasks within the system that, for one reason or another, we don’t want to let our end users perform (e.g. mass create/update/delete operations on data, flipping switches that turn paid modules of the system on or off, etc). When we try to build new tools like this we often struggle with the level of effort required to build them. Effort Required Creating a whole new page in an existing web application can be a fairly large undertaking. You need to create the page and ensure it will have a layout that is consistent with the other pages in the app. You need to decide what types of input controls need to go onto the page. You need to ensure that everything uses the same style as the rest of the site. You need to figure out what the text on the page should say. Then, when you figure out that you forgot about an input that should really be present you might have to go back and re-work the entire thing. Oh, and in addition to all of that, you still have to, you know, write the code that actually performs the task. Everything other than the code that performs the task at hand is just overhead. We don’t need a fancy date picker control in a nicely styled page for the vast majority of our internal tools. We don’t even really need a page, for that matter. We just need a way to issue a command to the application and have it, in turn, execute the code that we’ve written to accomplish a given task. All we really need is a simple console application! Plumbing Problems A former co-worker of mine, John Sonmez, always advocated the Unix philosophy for building internal tools: start with something that runs at the command line, and then build a UI on top of that if you need to. John’s idea has a lot of merit, and we tried building out some internal tools as simple Console applications. Unfortunately, this was often easier said that done. Doing a “File –> New Project” to build out a tool for a mature system can be pretty daunting because that new project is totally empty.  In our case, the web application code had a lot of of “plumbing” built in: it managed authentication and authorization, it handled database connection management for our multi-tenanted architecture, it managed all of the context that needs to follow a user around the application such as their timezone and regional/language settings. In addition, the configuration file for the web application  (a web.config in our case because this is an ASP .NET application) is large and would need to be reproduced into a similar configuration file for a Console application. While most of these problems are could be solved pretty easily with some refactoring of the codebase, building Console applications for internal tools still potentially suffers from one pretty big drawback: you’d have to execute them on a machine with network access to all of the needed resources. Obviously, our web servers can easily communicate the the database servers and can publish messages to our service bus, but the same is not true for all of our developer and support personnel workstations. We could have everyone run these tools remotely via RDP or SSH, but that’s a bit cumbersome and certainly a lot less convenient than having the tools built into the web application that is so easily accessible. Mix and Match So we need a way to build tools that are easily accessible via the web application but also don’t require the overhead of creating a user interface. This is where my idea comes into play: why not just build a command line interface into the web application? If it’s part of the web application we get all of the plumbing that comes along with that code, and we’re executing everything on the web servers which means we’ll have access to any external resources that we might need. Rather than having to incur the overhead of creating a brand new page for each tool that we want to build, we can create one new page that simply accepts a command in text form and executes it as a request on the web server. In this way, we can focus on writing the code to accomplish the task. If the tool ends up being heavily used, then (and only then) should we consider spending the time to build a better user experience around it. To be clear, I’m not trying to downplay the importance of building great user experiences into your system; we should all strive to provide the best UX possible to our end users. I’m only advocating this sort of bare-bones interface for internal consumption by the technical staff that builds and supports the software. This command line interface should be the “back end” to a highly polished and eye-pleasing public face. Implementation As I mentioned at the beginning of this post, this is an idea that I’ve had for awhile but have only recently started building out. I’ve outlined some general guidelines and design goals for this effort as follows: Text in, text out: In the interest of keeping things as simple as possible, I want this interface to be purely text-based. Users will submit commands as plain text, and the application will provide responses in plain text. Obviously this text will be “wrapped” within the context of HTTP requests and responses, but I don’t want to have to think about HTML or CSS when taking input from the user or displaying responses back to the user. Task-oriented code only: After building the initial “harness” for this interface, the only code that should need to be written to create a new internal tool should be code that is expressly needed to accomplish the task that the tool is intended to support. If we want to encourage and enable ourselves to build good tooling, we need to lower the barriers to entry as much as possible. Built-in documentation: One of the great things about most command line utilities is the ‘help’ switch that provides usage guidelines and details about the arguments that the utility accepts. Our web-based command line utility should allow us to build the documentation for these tools directly into the code of the tools themselves. I finally started trying to implement this idea when I heard about a fantastic open-source library called CLAP (Command Line Auto Parser) that lets me meet the guidelines outlined above. CLAP lets you define classes with public methods that can be easily invoked from the command line. Here’s a quick example of the code that would be needed to create a new tool to do something within your system: 1: public class CustomerTools 2: { 3: [Verb] 4: public void UpdateName(int customerId, string firstName, string lastName) 5: { 6: //invoke internal services/domain objects/hwatever to perform update 7: } 8: } This is just a regular class with a single public method (though you could have as many methods as you want). The method is decorated with the ‘Verb’ attribute that tells the CLAP library that it is a method that can be invoked from the command line. Here is how you would invoke that code: Parser.Run(args, new CustomerTools()); Note that ‘args’ is just a string[] that would normally be passed passed in from the static Main method of a Console application. Also, CLAP allows you to pass in multiple classes that define [Verb] methods so you can opt to organize the code that CLAP will invoke in any way that you like. You can invoke this code from a command line application like this: SomeExe UpdateName -customerId:123 -firstName:Jesse -lastName:Taber ‘SomeExe’ in this example just represents the name of .exe that is would be created from our Console application. CLAP then interprets the arguments passed in order to find the method that should be invoked and automatically parses out the parameters that need to be passed in. After a quick spike, I’ve found that invoking the ‘Parser’ class can be done from within the context of a web application just as easily as it can from within the ‘Main’ method entry point of a Console application. There are, however, a few sticking points that I’m working around: Splitting arguments into the ‘args’ array like the command line: When you invoke a standard .NET console application you get the arguments that were passed in by the user split into a handy array (this is the ‘args’ parameter referenced above). Generally speaking they get split by whitespace, but it’s also clever enough to handle things like ignoring whitespace in a phrase that is surrounded by quotes. We’ll need to re-create this logic within our web application so that we can give the ‘args’ value to CLAP just like a console application would. Providing a response to the user: If you were writing a console application, you might just use Console.WriteLine to provide responses to the user as to the progress and eventual outcome of the command. We can’t use Console.WriteLine within a web application, so I’ll need to find another way to provide feedback to the user. Preferably this approach would allow me to use the same handler classes from both a Console application and a web application, so some kind of strategy pattern will likely emerge from this effort. Submitting files: Often an internal tool needs to support doing some kind of operation in bulk, and the easiest way to submit the data needed to support the bulk operation is in a file. Getting the file uploaded and available to the CLAP handler classes will take a little bit of effort. Mimicking the console experience: This isn’t really a requirement so much as a “nice to have”. To start out, the command-line interface in the web application will probably be a single ‘textarea’ control with a button to submit the contents to a handler that will pass it along to CLAP to be parsed and run. I think it would be interesting to use some javascript and CSS trickery to change that page into something with more of a “shell” interface look and feel. I’ll be blogging more about this effort in the future and will include some code snippets (or maybe even a full blown example app) as I progress. I also think that I’ll probably end up either submitting some pull requests to the CLAP project or possibly forking/wrapping it into a more web-friendly package and open sourcing that.

  • Weblogic domain scale up using EM Grid Control 11gR1

    - by dmitry.nefedkin(at)oracle.com
    As you know a weblogic domain consists of set of servers running independently or in a cluster mode, sharing the distributed resources. And in most environments weblogic  cluster consists of multiple managed servers running simultaneously and working together to provide increased scalability and reliability.  These servers can run on the same machine, or be located on different machines.  It's a common task to increase a cluster's capacity by adding new machines to the cluster to host the new server instances.  You can do it by manually installing weblogic binaries to the new host and use pack/unpack commands to add a managed server to this new host.  But with Enterprise Manager Grid Control 11gR1 (EMGC) there is  another way - Fusion Middleware Domain Scale Up  procedure. I'm going to show you how it works.Here is a picture of  my medrec_oradb weblogic domain, what is registered in EMGC. It contains an admin server and a cluster MedRecCluster with  the single managed server MS1. Both admin and managed servers are on the same host oel46-vmware, it's a virtual machine with OEL 4.6 that runs inside our Oracle VM infrastructure.  And here are the application deployments, note that couple of applications are deployed to the cluster.First of all I have to prepare a new machine that will host new managed sever of my cluster. I created new VM with OEL 5.4 using the corresponding Oracle VM template available in Oracle E-Delivery site for Oracle Linux and Oracle VM and named it wls1032. Next step is to install Oracle EM Grid Control 11gR1 Agent to this new host.  You can download it from the OTN page and install it manually,  or you can use Agent Installation Deployment procedure available in EMGC  (Deployments->Agent Installation->Install Agent). Anyway, when you agent is up and running on the new machine, you will see it in EMGC Console in the Targets->Hosts subtab.Now we are ready to scale up our weblogic domain. Click the Deployments tab in Oracle Enterprise Manager Grid Control, and then click Deployment Procedure. Select a Fusion Middleware Domain Scale Up procedure from the list, and click Schedule Deployment. The first page of the FMW Domain Scale Up Wizard is displayed and you can proceed with the deployment process.Select the domain from list, enter the working directory on the admin server host, and also fill the weblogic credentials for the administration server console and the OS credentials for the  admin server host.  Click Next button.  The next step allows you to configure you domain, to add a new manager server to the cluster you should select the cluster in the tree and click Add Server button. Select the newly added server in a tree, choose the target host and  enter the configuration details of your managed server. You can also add new machine and node manager details.  Please note that you cannot change the values in  Domain Location and Fusion Middleware Home fields, so these locations on the target host will be the same as for the admin server host.   Working directory on the target host should have enough free space to store FMW home binaries and domain configuration files.  In my experience the working directories should have at least 3 Gb of free space.  The last thing you should fill is the OS credentials for the target host. The next steps allows you to schedule the execution of the procedure, it is started immediately in my example. The last step is just a review the configuration for the domain scale up. Click Submit to launch the process. You can track the status of the procedure execution by selecting Deployments->Deployment Procedures->Procedure Completion Status in the EMGC Console.As you can see in the picture below, the procedure consists of the many steps, and I'm going to share my experience about the issues that I had at some of the steps. Please keep in mind that you can always continue the execution from the last successfully completed step by clicking Retry button.Check OUI Prerequisites  step may fail if the target host does  not pass prerequisites checks for Weblogic Server installation such as amount of RAM, linux packages installed, etc. Create FMW Clone Archive step may fail if you do not have enough free space in the working directory on the administration server host.Transfer cloning archive to targets  step  may fail if the EMGC agents on the admin server host or on target host are not secured.   You should secure the agent by issuing ./emctl secure agent  command from $AGENT_HOME/bin directory and entering the agent registration password.Both Transfer cloning archive to targets and Apply Clone at target hosts steps may fail if you do not have enough free space in the working directory on the target host.

  • Tips on debugging collections

    - by Vincent Grondin
    The "Quick Watch" feature of Visual Studio is an awesome tool when debugging your stuff...  I use it all the time and quite often I end up exploring hashtables or lists of all sorts...  One thing I hate is when I have to explore Collections...  Good god did I lose time trying to find the inner member that contains my stuff when exploring collections...  Most collections have the inside member that you can search for and find and explore to see the list of things you wanted to look at.  Something in the likes of this.    I've known a little trick for a while now and I give it to everyone I end up debugging something with so I figured that probably not many people know about this...  Here's the tip...  Send the collection into an ArrayList in the QuickWatch window!  Yes, you heard me right, just type    new ArrayList(yourcollectionhere) in my case:    new ArrayList(this.Controls) in the expresion textbox and here's the result when you hit reevaluate! Pretty neat trick to make your debugging experience less of a pain when dealing with collections...    Happy debugging all !

  • Rackspace Cloud Servers in Europe?

    - by mit
    We have setup a cloud virtual server at rackspace in the US, but we use it from Europe. I found out I am not quite happy with the response time. Of course I knew that there would be some latency. But I am not sure if it is the overseas latency (ping is 120ms) or also the minimal resources. It is the smallest machine, 256 MB, 10 GB, running a Mediawiki on Ubuntu 10.04 64 bit. The Instance lives in the rackspace ORD1 datacenter. As soon as they have opened their new facilities in the UK we plan moving the incstance there. But we are planing more machines already. The pricing is quite attractive. I don't really want to do some measuring and benchmarking and this stuff, so I am asking just for your opinions and it would be nice to hear what you can tell from your experience. Maybe someone who uses such small instances in the US. And what can we really expect if we upgrade to more resources.

  • Growing mobile developers inside a web development org

    - by Arkaaito
    I work for a "mature web startup" as a web developer (mainly using PHP). Our main site has about 8 million registered members at the moment. However, the site is basically impossible to use on anything that's not a real computer. One of our most-requested features, if not the most requested, is a mobile app or mobile version of the site. I think we need to do it. Management thinks we need to do it. In fact, everyone in the company thinks we need to do it. But it's nigh impossible to hire someone with iPhone/Android skills in the present market. I'm the only person at the company with any level of mobile development experience currently, and I'm not that good (yet), so I'm seeking comments on how to bootstrap a capacity for mobile development. Anything from general tips (should I focus on developing my personal skills first or try to pick up a more experienced mobile dev?) to specific recommendations on training, etc., may be helpful, as long as it doesn't reduce to "sucks to be you." :-)

  • Moving from Test Automation to Development

    - by avgvstvs
    I'm in an interesting quandary. I've been doing test automation using QTP for about 1.5 years, and am in the slow process of switching to a developer role in my same company. I also begin my Master's in CS this fall. An old friend is trying to recruit me for a Sr. Test Automation position that could potentially pay me $23k more for the exact same thing I do now. But obviously I would defer moving to development. The new company is much more technical overall (I would be moving from financial services to industrial automation, and they have MANY more software dev roles available. I know traditionally QA type jobs carry an odd "danger" tag, but test automation is really a different beast. Does anyone have any experience moving from test automation to development? Does the QA stigma exist? The extra $$ would be nice, but not at the expense of my career. I should note that my Master's will be on Systems/parallel programming, so one thought is that I'll get automatic consideraton for development upon completing my Master's. I also work 6hrs/wk doing game development with a friend.
