• 12 days to go for Messenger!

  - by TATWORTH

  In just over twelve days from now, the Messenger space probe will go into orbit around our innermost planet, Mercury. See http://messenger.jhuapl.edu/index.php for latest mission timings. After 2405 days in space and 15+ circuits of the sun (see http://messenger.jhuapl.edu/whereis/index.php), it about to go into orbit around Mercury. It has flown by Earth, Venus and Mercury in order to change velocity sufficiently to be able to go into orbit without requiring a massive amount of propellant.

• TOP 25 Most Dangerous Software Errors for 2010

  - by TATWORTH

  A top 25 most dangerous list of software errors has been published at http://www.sans.org/top25-software-errors/ Insterestingly the top error listed was cross site scripting. So what do you do if have to accept HTML input? I suggest that write a white list filter function to allow through only acceptable mark-up. A basis for such a function can be found in the common filter function at http://commonfilter.codeplex.com/

• XHTML fix solution republished

  - by TATWORTH

  As a post VS2010 SP1 installation activity, I am recompiling all my open source projects. The first is XHTMLFIX at http://xhtmlfix.codeplex.com/ This LGPL project has simple fixes to ASP.NET 2.0/4.0 to achieve XHTML compliance as measured by the W3C tests at http://validator.w3.org/ The XHTML project shows as untrue the commonly held belief that MVP or MVC are necessary for producing XHTML compliant web pages. Incidentally the other supposed advantage of MVP and MVC over web forms of easier testing is also very dubious as web forms can be tested by systems such as Selenium or WaTiN. I have used NUnitASP (alas sadly discontinued) with web forms and found it be more effective than unit testing MVP. Now if you prefer the MVP and / or MVC approach over Web forms then fine, that is your preferance. Now if you can find an example where ASP.NET 4.0 Web forms properly written do not produce XHTML compliant markup, I would be glad of your example and will look at ways of modifying the markup to be XHTML compliant.

• Free book from Microsoft: - Exploring CQRS and Event Sourcing

  - by TATWORTH

  At http://www.microsoft.com/en-us/download/details.aspx?id=34774, Microsoft are providing a free book on Exploring CQRS and Event Sourcing"This guide is focused on building highly scalable, highly available, and maintainable applications with the Command & Query Responsibility Segregation and the Event Sourcing architectural patterns. It presents a learning journey, not definitive guidance. It describes the experiences of a development team with no prior CQRS proficiency in building, deploying (to Windows Azure), and maintaining a sample real-world, complex, enterprise system to showcase various CQRS and ES concepts, challenges, and techniques. The development team did not work in isolation; we actively sought input from industry experts and from a wide group of advisors to ensure that the guidance is both detailed and practical. "

• Tales from the Coalface - A Software Hero I have met.

  - by TATWORTH

  I use the word Hero to describe my friend, who wrote a word processor program that did not use a keyboard. This program was used by a 34-year woman who previously was unable to communicate. The first thing she wrote after she learned how to use it was "Nicole loves Mum". The details of this heroic act are documented in the Hansard (record of proceedings) of the Australian House of Parliament. A copy is available at http://masonsoft.co.uk/hansard.pdf

• Help file formats - MSHA files v CHM files

  - by TATWORTH

  Recently I was tasked with producing a help file from a C#/WPF/Crystal Reports application using Sandcastle. I have previously blogged about the problems in doing that and the change that is going into the next version of Sandcastle that allows the vagaries of Crystal (this missing BusinessObjects.Licensing.KeycodeDecoder) to be handled. At http://social.msdn.microsoft.com/Forums/en-US/devdocs/thread/0b110502-f5bb-4c56-96a5-4347a2a7a68a/, I describe how I tried each of the formats. Two of the formats could not be built and the error messages were not exactly helpful as to the cause. These two formats turned out to be obsolete. The MSHA format worked but was not suitable for a standalone application, so that left me with the older CHM format. I therefore asked on that thread "will the HTML Help 1 (CHM) format continue to be supported for the foreseeable future?".Rob Chandler, MVP in help systems, gave a very helpful answer, to the effect that there is not yet a replacement for the CHM format.

• Apress "Pro DLR in .NET 4' - ISBN 978-1-430203066-3 - Conclusion

  - by TATWORTH

  Having finished Pro DLR in .Net 4, I have concluded that this is a book that needs to be read through several times and the examples worked through.  Since the Dynamic Language Runtime is as much a radical change as the the original Common Language Runtime, this is hardly surprising. Ultimatly the DLR will enable more niche programming languages, hence I recommend this book to Dot Net teams for when they have a requirement that justifies the effort.

• Fiddler - A useful free tool for checking Web Services (and web site) traffic

  - by TATWORTH

  Recently I had reason to be very glad that I had Fiddler. I was able to record some web service traffic and identify a problem as Fiddler can record both the call to a web service and response from the web service. By seeing the actual data traffic I was able to resolve a problem found in testing in less time than it has taken me to write this blog entry! This tool is also useful for studying general web site traffic. Fiddler is available from http://www.fiddler2.com/fiddler2/ There are training videos available on the above site.

• What is the R Language?

  - by TATWORTH

  I encountered the R Language recently with O'Reilly books and while from the context I knew it was a language for dealing with statistics, doing a web search for the support web site was futile. However I have now located the web site and it is at http://www.r-project.org/R is a free language available for a number of platforms including windows. CRAN mirrors are available at a number of locations worldwide.Here is the official description:"R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS."

• From the Coalface - 4 - Getting a connection string

  - by TATWORTH

  Creating a connection string by hand is quite difficult, however you create a connection string as follows: 1) Create an empty text file in windows explorer and rename it to X.UDL 2) Double click on it and the datalink provider dialog will appear. 3) Select the provider tab. Find the provider for your data access method and click next. 4) Select your source  5) Test the connection and save it. 6) Open X.UDL with a text editor to see your connections string. You can also look at http://www.connectionstrings.com/ for examples of connection strings.

• Tales from the Coal Face - Reporting errors

  - by TATWORTH

  One of the questions that comes up frequently, is "Is it worthwhile to report errors?".Last weekend, after installing the latest StyleCop I loaded up my copy of Power Collections. I found that StyleCop was now correctly picking up a lot of missing "this." statements, however there were now a number of false positives. Anticipating the need to submit sample code, I cleaned the solution and zipped it up.I reported this at http://stylecop.codeplex.com/discussions/357319.  The stylecop administrator promoted this report to a work item (see http://stylecop.codeplex.com/workitem/7285) and I uploaded the previously prepared Zip file. The StyleCop team was able to locate the problem and it is "Fixed in upcoming 4.7.27".The conclusion:Report errors!  Prepare sample code illustrating the error.

• Apress Books - 3 - Pro ASP.NET 4 CMS (ISBN 987-1-4302-2712-0) - Final comments

  - by TATWORTH

  This book is more than just  a book about an ASP.NET CMS system -  it has much practical advice and examples for the Dot Net web developer. I liked the use of JQuery to detect that JavaScript was not enabled. One chapter was about MemCached - this one chapter could justify the price of the book if you run a server farm and need to improve performance. Some links to get you started are: Windows Memcache at http://code.jellycan.com/memcached/ Dot Net Access Library at http://sourceforge.net/projects/memcacheddotnet/ The chapters on scripting, performance analysis and search engne optimisation all provide excellent examples. This certainly is a book that should be part of every Dot Net Web Development team library. Congratulations to the author and to Apress for publishing this book!

• "From the Coal Face" - 1 - What ILDASM can reveal!

  - by TATWORTH

  In a place far, far away, there was a project where the Architect decided on using embedded TSQL in a Dot Net application, rather than use stored procedures. I located ILDASM.EXE (my Framework 3.5 version lives at C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin on my home development PC) and created a shortcut to it in the SendTo folder. Now I could set about doing a simple demonstration to the Architect by taking one of the Dot Net EXE's with the embedded TSQL and sending it to ILDASM.  Since I had written most of the embedded TSQL, it was a matter of seconds before I located the embedded TSQL within the Exe. The TSQL that was supposed to be safely hidden within the EXE was easily located and and copied. (It should also be noted that we could have encrypted the stored procedures on loading them to the database.)

• Gallery of Exoplanets

  - by TATWORTH

  Space.com have put together a gallery of exoplanets (planets outside our solar system) at http://www.space.com/13986-gallery-smallest-alien-planets-exoplanets.htmlSome exoplanets have been discovered by monitoring the red/blue shift of the star, whereas others have been found by the transit method. The kepler space telescope is continuously monitoring a small patch of the sky for transits.Here are some of the more interesting (and eye-catching pictures). Remember so far the best image of an extra-solar planets has been a diffraction blur, but even just as artist's impressions based upon the best current evidence, they are very impressive. Have a look at the Gallery at http://www.space.com/13986-gallery-smallest-alien-planets-exoplanets.html, it is very impressive.

• How to ask questions on the Forums

  - by TATWORTH

  Based upon answering many questions on forums such as forums.asp.net, here are some tips on getting your questions answered, once you have exhausted searching on your own. Choose a concise but meaningful title but avoid words like "urgent" Post to the correct section of the forum - some people specialise in a particular section of a given forum Make it clear that you have already made an effort to answer yourself. Summerise the environmental context of your question e.g. If using SQL then state the version e.g. SQLExpress 2008 If you need to post a code or markup sample, tidy it up by removing extraneous blank lines and set the tab spacing to 2 rather than 4. Take your time composing the question so that it is set out as clearly as possible. Remember that the majority of people providing answers do so in their own time. Be very polite and thank those that help you.
