• Thank you South Florida for a successful SPSouthFLA

  - by Leonard Mwangi

  I wanted to officially thank the organizers, speakers, volunteers and the attendees of SharePoint Saturday South Florida. Being the first event in South Florida the reception was phenomenon and the group of speakers from keynote by Joel Oleson to session’s speakers from well renowned speakers like John Holliday, Randy Disgrill, Richard Harbridge, Ameet Phadnis, Fabian Williams, Chris McNulty, Jaime Velez to organizers like Michael Hinckley amongst others. With my Business Intelligence (BI) presentation being on the last track of the day, I spent very quality time networking with these great guys and getting the insider scope on International SharePoint Community from Joel and his son which was mesmerizing. I had a very active audience to a point where we couldn’t accommodate all the contents within the 1hr allocated time because they were very engaged and wanted a deep dive session on news features like PowerPivot, enhancements on PerformancePoint, Excel Services amongst others in order to understand the business value and how SharePoint 2010 is making the self-service BI become a reality. These community events allows the attendees experience technology first hand and network with MVPs, authors, experts providing high quality educational sessions usually for free which is a reason to attend. I have made the slides for my session available for download for those interested http://goo.gl/VaH5x

• Applying WCAG 2.0 to Non-Web ICT: second draft published from WCAG2ICT Task Force - for public review

  - by Peter Korn

  Last Thursday the W3C published an updated Working Draft of Guidance on Applying WCAG 2.0 to Non-Web Information and Communications Technologies. As I noted last July when the first draft was published, the motivation for this guidance comes from the Section 508 refresh draft, and also the European Mandate 376 draft, both of which seek to apply the WCAG 2.0 level A and AA Success Criteria to non-web ICT documents and software. This second Working Draft represents a major step forward in harmonization with the December 5th, 2012 Mandate 376 draft documents, including specifically Draft EN 301549 "European accessibility requirements for public procurement of ICT products and services". This work greatly increases the likelihood of harmonization between the European and American technical standards for accessibility, for web sites and web applications, non-web documents, and non-web software. As I noted last October at the European Policy Centre event: "The Accessibility Act – Ensuring access to goods and services across the EU", and again last month at the follow-up EPC event: "Accessibility - From European challenge to global opportunity", "There isn't a 'German Macular Degernation', a 'French Cerebral Palsy', an 'American Autism Spectrum Disorder'. Disabilities are part of the human condition. They’re not unique to any one country or geography – just like ICT. Even the built environment – phones, trains and cars – is the same worldwide. The definition of ‘accessible’ should be global – and the solutions should be too. Harmonization should be global, and not just EU-wide. It doesn’t make sense for the EU to have a different definition to the US or Japan." With these latest drafts from the W3C and Mandate 376 team, we've moved a major step forward toward that goal of a global "definition of 'accessible' ICT." I strongly encourage all interested parties to read the Call for Review, and to submit comments during the current review period, which runs through 15 February 2013. Comments should be sent to public-wcag2ict-comments-AT-w3.org. I want to thank my colleagues on the WCAG2ICT Task Force for the incredible time and energy and expertise they brought to this work - including particularly my co-authors Judy Brewer, Loïc Martínez Normand, Mike Pluke, Andi Snow-Weaver, and Gregg Vanderheiden; and the document editors Michael Cooper, and Andi Snow-Weaver.

• How best to keep bumbling, non-technical managers at bay and still deliver good work?

  - by Curious

  This question may be considered subjective (I got a warning) and be closed, but I will risk it, as I need some good advice/experience on this. I read the following at the 'About' page of Fog Creek Software, the company that Joel Spolsky founded and is CEO of: Back in the year 2000, the founders of Fog Creek, Joel Spolsky and Michael Pryor, were having trouble finding a place to work where programmers had decent working conditions and got an opportunity to do great work, without bumbling, non-technical managers getting in the way. Every high tech company claimed they wanted great programmers, but they wouldn’t put their money where their mouth was. It started with the physical environment (with dozens of cubicles jammed into a noisy, dark room, where the salespeople shouting on the phone make it impossible for developers to concentrate). But it went much deeper than that. Managers, terrified of change, treated any new idea as a bizarre virus to be quarantined. Napoleon-complex junior managers insisted that things be done exactly their way or you’re fired. Corporate Furniture Police writhed in agony when anyone taped up a movie poster in their cubicle. Disorganization was so rampant that even if the ideas were good, it would have been impossible to make a product out of them. Inexperienced managers practiced hit-and-run management, issuing stern orders on exactly how to do things without sticking around to see the farcical results of their fiats. And worst of all, the MBA-types in charge thought that coding was a support function, basically a fancy form of typing. A blunt truth about most of today's big software companies! Unfortunately not every developer is as gutsy (or lucky, may I say?) as Joel Spolsky! So my question is: How best to work with such managers, keep them at bay and still deliver great work?

• New spreadsheet accompanying SmartAssembly 6.0 provides statistics for prioritizing bug fixes

  - by Jason Crease

  One problem developers face is how to prioritize the many voices providing input into software bugs. If there is something wrong with a function that is the darling of a particular user, he or she tends to want action - now! The developer's dilemma is how to ascertain that the problem is major or minor, and when it should be addressed. Now there is a new spreadsheet accompanying SmartAssembly that provides exactly that information in an objective manner. This might upset those used to getting their way by being the loudest or pushiest, but ultimately it will ensure that the biggest problems get the priority they deserve. Here's how it works: Feature Usage Reporting (FUR) in SmartAssembly 6.0 provides a wealth of data about how your software is used by its end-users, but in the SmartAssembly UI the data isn't mined to its full extent. The new Excel spreadsheet for FUR extracts statistics from that data and presents them in easy-to-understand forms. I developed the spreadsheet feature in Microsoft Excel, using a fair amount of VBA. The spreadsheet connects directly to the database which stores the feature-usage data, and shows a wide variety of statistics and tables extracted from that data.  You want to know what percentage of users have used the 'Export as XML' button?  No problem.  How popular is v5.3 is compared to v5.1?  There's graphs for that. You need to know whether you have more users in Russia or Brazil? There's a big pie chart for that. I recently witnessed the spreadsheet in use here at Red Gate Software. My bug is exposed as minor While testing new features in .NET Reflector, I found a usability bug in the Refresh button and filed it in the Red Gate bug-tracking system. The bug was labelled "V.NEXT MINOR," which means it would be fixed in the next point release. Although I'm a professional tester, I'm not much different than most software users when they discover a bug that affects them personally: I wanted it fixed immediately. There was an ulterior motive at play here, of course. I would get to see my colleagues put the spreadsheet to work. The Reflector team loaded up the spreadsheet to view the feature-usage statistics that SmartAssembly collected for the refresh button. The resulting statistics showed that only 8% of users have ever pressed the Refresh button, and only 2.6% of sessions involve pressing the button. When Refresh is used, it's only pressed on average 1.6 times a session, with a maximum of 8 times during a session. This was in stark contrast to what I was doing as a conscientious tester: pressing it dozens of times per session. The spreadsheet provides evidence that my bug was a minor one. On to more serious things Based on the solid evidence uncovered by the spreadsheet, the Reflector team concluded that my experience does not represent that of the vast majority of Reflector's recorded users. The Reflector team had ample data to send me back to my desk and keep the bug classified as "V.NEXT MINOR." The team then went back to fixing more serious bugs. If I'm in the shoes of the user, I might not be thoroughly happy, but I cannot deny that the evidence clearly placed me in a very small minority. Next time I'm hoping the spreadsheet will prove that my bug is more important. Find out more about Feature-Usage Reporting here. The spreadsheet is available for free download here.

• How to drastically improve code coverage?

  - by Peter Kofler

  I'm tasked with getting a legacy application under unit test. First some background about the application: It's a 600k LOC Java RCP code base with these major problems massive code duplication no encapsulation, most private data is accessible from outside, some of the business data also made singletons so it's not just changeable from outside but also from everywhere. no business model, business data is stored in Object[] and double[][], so no OO. There is a good regression test suite and an efficient QA team is testing and finding bugs. I know the techniques how to get it under test from classic books, e.g. Michael Feathers, but that's too slow. As there is a working regression test system I'm not afraid to aggressively refactor the system to allow unit tests to be written. How should I start to attack the problem to get some coverage quickly, so I'm able to show progress to management (and in fact to start earning from safety net of JUnit tests)? I do not want to employ tools to generate regression test suites, e.g. AgitarOne, because these tests do not test if something is correct.

• Detect Unicode Usage in SQL Column

  One optimization you can make to a SQL table that is overly large is to change from nvarchar (or nchar) to varchar (or char).  Doing so will cut the size used by the data in half, from 2 bytes per character (+ 2 bytes of overhead for varchar) to only 1 byte per character.  However, you will lose the ability to store Unicode characters, such as those used by many non-English alphabets.  If the tables are storing user-input, and your application is or might one day be used internationally, its likely that using Unicode for your characters is a good thing.  However, if instead the data is being generated by your application itself or your development team (such as lookup data), and you can be certain that Unicode character sets are not required, then switching such columns to varchar/char can be an easy improvement to make. Avoid Premature Optimization If you are working with a lookup table that has a small number of rows, and is only ever referenced in the application by its numeric ID column, then you wont see any benefit to using varchar vs. nvarchar.  More generally, for small tables, you wont see any significant benefit.  Thus, if you have a general policy in place to use nvarchar/nchar because it offers more flexibility, do not take this post as a recommendation to go against this policy anywhere you can.  You really only want to act on measurable evidence that suggests that using Unicode is resulting in a problem, and that you wont lose anything by switching to varchar/char. Obviously the main reason to make this change is to reduce the amount of space required by each row.  This in turn affects how many rows SQL Server can page through at a time, and can also impact index size and how much disk I/O is required to respond to queries, etc.  If for example you have a table with 100 million records in it and this table has a column of type nchar(5), this column will use 5 * 2 = 10 bytes per row, and with 100M rows that works out to 10 bytes * 100 million = 1000 MBytes or 1GB.  If it turns out that this column only ever stores ASCII characters, then changing it to char(5) would reduce this to 5*1 = 5 bytes per row, and only 500MB.  Of course, if it turns out that it only ever stores the values true and false then you could go further and replace it with a bit data type which uses only 1 byte per row (100MB  total). Detecting Whether Unicode Is In Use So by now you think that you have a problem and that it might be alleviated by switching some columns from nvarchar/nchar to varchar/char but youre not sure whether youre currently using Unicode in these columns.  By definition, you should only be thinking about this for a column that has a lot of rows in it, since the benefits just arent there for a small table, so you cant just eyeball it and look for any non-ASCII characters.  Instead, you need a query.  Its actually very simple: SELECT DISTINCT(CategoryName)FROM CategoriesWHERE CategoryName <> CONVERT(varchar, CategoryName) Summary Gregg Stark for the tip. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Book: DevOps for Developers

  - by Tori Wieldt

  We all know development and operations often act like silos, with "Just throw it over the wall!" being the battle cry. Many organizations unwittingly contribute to gaps between teams, with management by (competing) objectives; a clash of Agile practices vs. more conservative approaches; and teams using different sets of tools, such as Nginx, OpenEJB, and Windows on developers' machines and Apache, Glassfish, and Linux on production machines. At best, you've got sub-optimal collaboration, at worst, you've got the Hatfields and the McCoys.  The book DevOps for Developers helps bridge the gap between development and operations by aligning incentives and sharing approaches for processes and tools. It introduces DevOps as a modern way of bringing development and operations together. It also means to broaden the usage of Agile practices to operations to foster collaboration and streamline the entire software delivery process in a holistic way. Some single aspects of DevOps may not be new, for example, you may have used the tool Puppet for years already, but with a new mindset ("my job is not just to code, it's to serve the customer in the best way possible") and a complete set of recipes, you'll be well on your way to success. DevOps for Developers also by provides real-world use cases (e.g., how to use Kanban or how to release software). It provides a way to be successful in the real development/operations world. DevOps for Developers is written my Michael Hutterman, Java Champion, and founder of the Cologne Java User Group. "With DevOps for Developers, developers can learn to apply patterns to improve collaboration between development and operations as well as recipes for processes and tools to streamline the delivery process," Hutterman explains.

• JSR Updates - Multiple JSRs migrate to latest JCP version

  - by Heather VanCura

  As part of the JCP.Next reform effort, many JSRs have migrated to the latest version of the JCP program in the last month.  These JSRs' Spec Leads and Expert Groups are contributing to the strides the JCP has been making to enable greater community transparency, participation and agility to the working of the JSR development through the JCP program. Any other JSR Spec Leads interested in migrating to the latest JCP version, now JCP 2.9, as of 13 November, incorporating the Merged Executive Committee (EC), see the Spec Lead Guide for instructions on migrating to the latest JCP version.  For JCP 2.8 JSRs, you are effectively already operating under JCP 2.9 since there are no longer two ECs.  This is the difference for JCP 2.8 JSRs migrating to JCP 2.9 -- a merged EC.  To make the migration official, just inform your Expert Group on a public channel and email your request to admin at jcp.org. JSR 310, Date and Time API, led by Stephen Colebourne and Michael Nascimento and Oracle (Roger Riggs)  JSR 349, Bean Valirdation 1.1, led by RedHat (Emmanuel Bernard) JSR 350, Java State Management, led by Oracle (Mitch Upton) JSR 339, JAX-RS 2.0: The Java API for RESTful Web Services, led by Oracle, (Santiago Pericas-Geertsen and Marek Potociar) JSR 347, Data Grids for the Java Platform, led by RedHat (Manik Surtani)

• IE does not send NTLM domain

  - by Buddy Casino

  Hi! I have a problem with NTLM single-sign-on with IE8. We've got multiple domain controllers and users from multiple domains that we try to authenticate to a web application via NTLMv1 passthru. Somehow IE fails to send the user's domain in the NTLM Type 1 message. This has the effect that the webapp can not match users properly to their domain controllers, resulting in failed logon attempts, because a user from domain X tries to authenticate to domain controller Y. This problem does not occur with Firefox, as it always sends the correct domain header. So: how do I get IE to send the domain in the NTLM header? Grateful for any help, Michael

  I’m pleased to announce that a new XAML-Based User Group has started in Birmingham, Alabama. The group is being hosted by Michael Crump and Jonathan Marbutt. The reason is very simple: we feel that Birmingham needs a fresh start. We are both very passionate about .NET and are hoping to share our experiences with the community. We have created a site (http://allaboutxaml.net) and our first meetup is now scheduled. We are here to discuss all things that have to do with xaml. This includes Silverlight, WPF, Windows Phone 7, Surface, Lightswitch and Silverlight with SharePoint 2010. We: believe strongly in xaml and are passionate about what we talk about. believe in an open-forum. believe a user group should be FUN as well as educational. do not claim to be an expert on anything, we are here to share. record every presentation and put it on the web for others to benefit. meet monthly but are flexible on the actual date. do our events outside of technical colleges. have families and our meetings start and stop on time. welcome new speakers. welcome adult beverages. Our first meeting is going to be on February 15th, 2011 (6PM), at Logan's on HWY 280. It is going to be more of a meetup than a meeting. I would like to discuss current xaml-based projects that you are working on and get to know one another. If you are interested in coming then please sign up here so that we know how many to expect. Please visit our site to find out more about us: http://allaboutxaml.net.

• Force users to access SSL site using specific host header

  - by mwillmott

  Hi, So i am running IIS7 with one SSL site on it. I have a few different domains and subdomains that all point to my external IP. When using http they all direct to their respective sites using host headers. Whenever someone uses https on any of the domains they all point to my SSL site. I only want people who type in https://sub.domain.com (for example) to end up at my secure site and for anything else to just not go there, it can throw an error or direct to the http version, it doesn't matter. Is there a way of getting IIS7 to check the host header and throw an error if it doesn't match my specific subdomain? Thanks, Michael

  The battle between Java vs. C# has been a big debate amongst the development community over the last few years. Both languages have specific pros and cons based on the needs of a particular project. In general both languages utilize a similar coding syntax that is based on C++, and offer developers similar functionality. This being said, the communities supporting each of these languages are very different. The divide amongst the communities is much like the political divide in America, where the Java community would represent the Democrats and the .Net community would represent the Republicans. The Democratic Party is a proponent of the working class and the general population. Currently, Java is deeply entrenched in the open source community that is distributed freely to anyone who has an interest in using it. Open source communities rely on developers to keep it alive by constantly contributing code to make applications better; essentially they develop code by the community. This is in stark contrast to the C# community that is typically a pay to play community meaning that you must pay for code that you want to use because it is developed as products to be marketed and sold for a profit. This ties back into my reference to the Republicans because they typically represent the needs of business and personal responsibility. This is emphasized by the belief that code is a commodity and that it can be sold for a profit which is in direct conflict to the laissez-faire beliefs of the open source community. Beyond the general differences between Java and C#, they also target two different environments. Java is developed to be environment independent and only requires that users have a Java virtual machine running in order for the java code to execute. C# on the other hand typically targets any system running a windows operating system and has the appropriate version of the .Net Framework installed. However, recently there has been push by a segment of the Open source community based around the Mono project that lets C# code run on other non-windows operating systems. In addition, another feature of C# is that it compiles into an intermediate language, and this is what is executed when the program runs. Because C# is reduced down to an intermediate language called Common Language Runtime (CLR) it can be combined with other languages that are also compiled in to the CLR like Visual Basic (VB) .Net, and F#. The allowance and interaction between multiple languages in the .Net Framework enables projects to utilize existing code bases regardless of the actual syntax because they can be compiled in to CLR and executed as one codebase. As a software engineer I personally feel that it is really important to learn as many languages as you can or at least be open to learn as many languages as you can because no one language will work in every situation.  In some cases Java may be a better choice for a project and others may be C#. It really depends on the requirements of a project and the time constraints. In addition, I feel that is really important to concentrate on understanding the logic of programming and be able to translate business requirements into technical requirements. If you can understand both programming logic and business requirements then deciding which language to use is just basically choosing what syntax to write for a given business problem or need. In regards to code refactoring and dynamic languages it really does not matter. Eventually all projects will be refactored or decommissioned to allow for progress. This is the way of life in the software development industry. The language of a project should not be chosen based on the fact that a project will eventually be refactored because they all will get refactored.

• Happy Tau Day! (Or: How Some Mathematicians Think We Should Retire Pi) [Video]

  - by Jason Fitzpatrick

  When you were in school you learned all about Pi and its relationship to circles and turn-based geometry. Some mathematicians are rallying for a new lesson, on about Tau. Michael Hartl is a mathematician on a mission, a mission to get people away from using Pi and to start using Tau. His manifesto opens: Welcome to The Tau Manifesto. This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension. For millennia, the circle has been considered the most perfect of shapes, and the circle constant captures the geometry of the circle in a single number. Of course, the traditional choice of circle constant is p—but, as mathematician Bob Palais notes in his delightful article “p Is Wrong!”,1 p is wrong. It’s time to set things right. Why is Pi wrong? Among the arguments is that Tau is the ration of a circumference to the radius of a circle and defining circles by their radius is more natural and that Pi is a 2-factor number but with Tau everything is based of a single unit–three quarters of a turn around a Tau-defined circle is simply three quarters of a Tau radian. Watch the video above to see the Tau sequence (which begins 6.2831853071…) turned into a musical composition. For more information about Tau hit up the link below to read the manifesto.

• 12.04 WiFi issue on a particular access point

  - by user71706

  I have a WiFi access point that I connect to a PC to share its Internet connection with multiple machines, in a training environment. All the machines with 11.04 connect to this access point with no problem, and can access any server on the Internet. These machines have an Intel Wireless -N 1030 BGN chipset (as reported by lspci). Now, my problem is that I don't manage to connect 12.04 machines to this wireless network. The systems I tried do manage to connect (confirmed by Network Manager), but when I try to access a website like http://kernel.org, the browser shows "Connecting to kernel.org...", but displays a "The connection has timed out" error page. Other symptoms: Name resolution works (for example 'nslookup kernel.org') finds kernel.org's IP address 'ping kernel.org' doesn't work The same 12.04 machines have no problem at all with other wireless networks. So there is probably something weird in my access point (though the 11.04 machines are not impacted). Would you have any suggestions for investigating this issue? Thanks, Michael.

• Comparing Apples and Pairs

  - by Tony Davis

  A recent study, High Costs and Negative Value of Pair Programming, by Capers Jones, pulls no punches in its assessment of the costs-to- benefits ratio of pair programming, two programmers working together, at a single computer, rather than separately. He implies that pair programming is a method rushed into production on a wave of enthusiasm for Agile or Extreme Programming, without any real regard for its effectiveness. Despite admitting that his data represented a far from complete study of the economics of pair programming, his conclusions were stark: it was 2.5 times more expensive, resulted in a 15% drop in productivity, and offered no significant quality benefits. The author provides a more scientific analysis than Jon Evans’ Pair Programming Considered Harmful, but the theme is the same. In terms of upfront-coding costs, pair programming is surely more expensive. The claim of productivity loss is dubious and contested by other studies. The third claim, though, did surprise me. The author’s data suggests that if both the pair and the individual programmers employ static code analysis and testing, then there is no measurable difference in the resulting code quality, in terms of defects per function point. In other words, pair programming incurs a massive extra cost for no tangible return in investment. There were, inevitably, many criticisms of his data and his conclusions, a few of which are persuasive. Firstly, that the driver/observer model of pair programming, on which the study bases its findings, is far from the most effective. For example, many find Ping-Pong pairing, based on use of test-driven development, far more productive. Secondly, that it doesn’t distinguish between “expert” and “novice” pair programmers– that is, independently of other programming skills, how skilled was an individual at pair programming. Thirdly, that his measure of quality is too narrow. This point rings true, certainly at Red Gate, where developers don’t pair program all the time, but use the method in short bursts, while tackling a tricky problem and needing a fresh perspective on the best approach, or more in-depth knowledge in a particular domain. All of them argue that pair programming, and collective code ownership, offers significant rewards, if not in terms of immediate “bug reduction”, then in removing the likelihood of single points of failure, and improving the overall quality and longer-term adaptability/maintainability of the design. There is also a massive learning benefit for both participants. One developer told me how he once worked in the same team over consecutive summers, the first time with no pair programming and the second time pair-programming two-thirds of the time, and described the increased rate of learning the second time as “phenomenal”. There are a great many theories on how we should develop software (Scrum, XP, Lean, etc.), but woefully little scientific research in their effectiveness. For a group that spends so much time crunching other people’s data, I wonder if developers spend enough time crunching data about themselves. Capers Jones’ data may be incomplete, but should cause a pause for thought, especially for any large IT departments, supporting commerce and industry, who are considering pair programming. It certainly shouldn’t discourage teams from exploring new ways of developing software, as long as they also think about how to gather hard data to gauge their effectiveness.

• In the Aggregate: How Will We Maintain Legacy Systems? [closed]

  - by Jim G.

  NEW YORK - With a blast that made skyscrapers tremble, an 83-year-old steam pipe sent a powerful message that the miles of tubes, wires and iron beneath New York and other U.S. cities are getting older and could become dangerously unstable. July 2007 Story About a Burst Steam Pipe in Manhattan We've heard about software rot and technical debt. And we've heard from the likes of: "Uncle Bob" Martin - Who warned us about "the consequences of making a mess". Michael C. Feathers - Who gave us guidance for 'Working Effectively With Legacy Code'. So certainly the software engineering community is aware of these issues. But I feel like our aggregate society does not appreciate how these issues can plague working systems and applications. As Steve McConnell notes: ...Unlike financial debt, technical debt is much less visible, and so people have an easier time ignoring it. If this is true, and I believe that it is, then I fear that governments and businesses may defer regular maintenance and fortification against hackers until it is too late. [Much like NYC and the steam pipes.] My Question: Is there a way that we can avoid the software equivalent of NYC and the steam pipes?
