  • Working with Temporal Data in SQL Server

    - by Dejan Sarka
    My third Pluralsight course, Working with Temporal Data in SQL Server, is published. I am really proud on the second part of the course, where I discuss optimization of temporal queries. This was a nearly impossible task for decades. First solutions appeared only lately. I present all together six solutions (and one more that is not a solution), and I invented four of them. http://pluralsight.com/training/Courses/TableOfContents/working-with-temporal-data-sql-server

  • The importance of Unit Testing in BI

    - by Davide Mauri
    One of the main steps in the process we internally use to develop a BI solution is the implementation of Unit Test of you BI Data. As you may already know, I’ve create a simple (for now) tool that leverages NUnit to allow us to quickly create Unit Testing without having to resort to use Visual Studio Database Professional: http://queryunit.codeplex.com/ Once you have a tool like this one, you can start also to make sure that your BI solution (DWH and CUBE) is not only structurally sound (I mean, the cube or the report gets processed correctly), but you can also check that the logical integrity of your business rules is enforced. For example let’s say that the customer tell you that they will never create an invoice for a specific product-line in 2010 since that product-line is dismissed and will never be sold again. Ok we know that this in theory is true, but a lot of this business rule effectiveness depends on the fact the people does not do a mistake while inserting new orders/invoices and the ERP used implements a check for this business logic. Unfortunately these last two hypotesis are not always true, so you may find yourself really having some invoices for a product line that doesn’t exists anymore. Maybe this kind of situation in future will be solved using Master Data Management but, meanwhile, how you can give and idea of the data quality to your customers? How can you check that logical integrity of the analytical data you produce is exactly what you expect? Well, Unit Testing of a DWH or a CUBE can be a solution. Once you have defined your test suite, by writing SQL and MDX queries that checks that your data is what you expect to be, if you use NUnit (and QueryUnit does), you can then use a tool like NUnit2Report to create a nice HTML report that can be shipped via email to give information of data quality: In addition to that, since NUnit produces an XML file as a result, you can also import it into a SQL Server Database and then monitor the quality of data over time. I’ll be speaking about this approach (and more in general about how to “engineer” a BI solution) at the next European SQL PASS Adaptive BI Best Practices http://www.sqlpass.org/summit/eu2010/Agenda/ProgramSessions/AdaptiveBIBestPratices.aspx I’ll enjoy discussing with you all about this, so see you there! And remember: “if ain't tested it's broken!” (Sorry I don’t remember how said that in first place :-)) Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Silverlight User Group of Switzerland (SLUGS)

    - by Laurent Bugnion
    Last Thursday, the Silverlight Firestarter event took place in Redmond, and was streamed live to a large audience worldwide (around 20’000 people). Approximately 30 if them were in Wallisellen near Zurich, in Microsoft Switzerland’s offices. This was not only a great occasion to learn more about the future of Silverlight and to see great demos, but also it was the very first meeting of the Silverlight User Group of Switzerland (SLUGS). Having 30 people for a first meeting was a great success, especially if we consider that it was REALLY cold that night, that it had snowed 20 cm the night before! We all had a good time, and 3 lucky winners went back home with a prize: One LG Optimus 7 Windows Phone and two copies of Silverlight 4 Unleashed. Congratulations to the winners! After the keynote (which went in a whirlwind, shortest 90 minutes ever!), we all had pizza and beverages generously sponsored by the Swiss DPE team, of which not less than 5 guys came to the event! Thanks to Stefano, Ronnie, Sascha, Big Mike and Ken for attending! We decided to have meetings every month. Stay tuned for announcements on when and where the events will take place. We are also in the process of creating various groups online where the attendees can find more information. For instance, I created a group on Flickr where the pictures taken at events will be published. The group is public, and the pictures of the first event are already online! We also have the already known page at http://www.slugs.ch/, check it out. A national group Even though the first event was in Zurich, and that 3 of the founding members live nearby, we would like to try and be a national group. That means having events sometimes in other parts of Switzerland, collaborating with other local user groups, etc. Stay tuned for more Join! We want you, we need you If you are doing Silverlight, for a living or as a hobby, if you are interested in user experience, XAML, Expression Blend and many more topics, you should consider joining! This is a great occasion to exchange experiences, to learn from Silverlight experts, to hear sessions about various topics related to Silverlight, etc. If you want to talk about a topic that is of interest to you, If you want to propose a topic of discussion Or if you just want to hang out then go to http://www.slugs.ch and register!

    - by kasparov
    Other than Indie game development, C# is also used for in house tool development at large studios. I have two questions -: 1) Is microsoft planning to release a native C# compiler sharing the backend code generator with the C++ compiler? http://www.compilerjobs.com/db/jobs_view.php?editid1=648 2) If microsoft IS planning a native C# compiler, then can C# replace C++ as the industry standard in AAA vedio games?

  • ISO Mount for Windown 7 and/or Server 2008

    - by Eric Johnson
    Apparently it's hard to locate a free ISO mapper these days.  Like most people I've use Microsoft's Virtual CD ROM to mount ISO images on XP and server 2003 machines.   This will not work in Windows 7 and Server 2008 machines.  Therefore, I recommend people try out magic ISO instead.   It's freeware and can be downloaded from the following URL. http://www.magiciso.com/tutorials/miso-magicdisc-history.htm

  • Search files blazing fast

    If you know there is a file somewhere on your machine, but you cannot find it with the default Windows Search Tools (that why they tend to call it Windows Search and not Windows Find ) then switch to a tool that really works. Go to http://www.voidtools.com/ to download your copy of Everything. The download is only small (350KB), it indexes fast (within 5 mins) and searches my complete computer even faster then I can type. I only blame David Carpenter for not spreading the word more aggressively and for not developing this earlier.

  • Large File Upload in SharePoint 2010

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Okay this is a big BIG B-I-G problem. And with SP2010 it’s going to be more prominent, because atleast at the server side, SharePoint can support large files much much better than SharePoint 2007 ever did. The issue with very large files being uploaded through any browser based API are - Reliably transferring gigabyte or bigger files without breakages over a protocol like HTTP, which is better suited for tiny transfers like images and text. Not killing your browser because it has to load all that in memory Not killing your web server because All that you upload through HTTP post, first gets streamed into IIS Memory, w3wp.exe memory before the ENTIRE FILE finishes uploading .. before it is stored. Which means, You cannot show an accurate and live progress bar of the upload, IIS gives you no such accurate metric of an upload. All the counters it gives you are approximate. Your w3wp.exe eats up all server memory – 4GB of it, for a 4GB upload. A thread is kept busy for the entire duration of the upload, thereby greatly limiting your web server’s capability to serve newer requests. Kills effective load balancing. Not killing your content database because, As you are uploading a very large file, that large file gets written sequentially into the DB, and therefore for a very large file very severely impacts the database performance. I had put together another video showing RBS usage in SharePoint 2010. I talked about many practical ramifications of using RBS in SharePoint in that video. Note that enabling large file support will never ever be a point and click job, simply because there are too many questions one needs to ask, and too many things one needs to plan for. However, one part that will remain common across all large file upload scenarios, in SharePoint or outside of SharePoint is to do it efficiently while not killing the web server. In this video, I describe using the Telerik Silverlight Upload control with SharePoint 2010 to enable efficient large file uploads in SharePoint. Presenting .. The video Comment on the article ....

  • What is the usage of Splay Trees in the real world?

    - by Meena
    I decided to learn about balanced search trees, so I picked 2-3-4 and splay trees. What are the examples of splay trees usage in the real world? In this Cornell: http://www.cs.cornell.edu/courses/cs3110/2009fa/recitations/rec-splay.html I read that splay trees are 'A good example is a network router'. But from rest of the explanation seams like network routers use hash tables and not splay trees since the lookup time is constant instead of O(log n).

  • How to perform feature upgrade in SharePoint2010 part1

    - by ybbest
    Once your custom SharePoint solution went into production. Any changes made to it require you to perform feature upgrade. Today, I’d like to show you how to perform feature upgrade. For the first version of my solution, I deploy a document library with a custom document set content type. You can download the solution here. Once you extract your solution, the first version is in the original folder. In order to deploy the original solution, you need to run the sitecreation.ps1 in the script folder. Next, I will modify the solution so that I will index the application number in the document library I just created in my original solution. 1. Modify the ApplicationLibrary.Template.xml as highlighted below: 2. Adding the following code into the feature event receiver. public override void FeatureUpgrading(SPFeatureReceiverProperties properties, string upgradeActionName, System.Collections.Generic.IDictionary<string, string> parameters) { base.FeatureUpgrading(properties, upgradeActionName, parameters); SPWeb web = GetFeatureWeb(properties); switch (upgradeActionName) { case "IndexApplicationNumber": SPList applicationLibrary = web.Lists.TryGetList(ApplicationLibraryNamesConstant.ApplicationLibraryName); if (applicationLibrary != null) { SPField queueField = applicationLibrary.Fields["ApplicationNumber"]; queueField.Indexed = true; queueField.Update(); } break; } } 3. Package your solution and run the feature upgrade PowerShell script. $wspFolder ="v1.1" $scriptPath=Split-Path $myInvocation.MyCommand.Path $siteUrl = "http://ybbest" $featureToCheckGuid="1b9d84cd-227d-45f1-92d4-a43008aa8fe7" $requiredFeatureVersion="0.0.0.0" $siteUrlOfFeatureToBeChecked="http://ybbest" AppendLog "Starting Solution UpgradeSolutionAndFeatures.ps1" Magenta & "$scriptPath\UpgradeSolutionAndFeatures.ps1" $siteUrl $wspFolder $featureToCheckGuid $requiredFeatureVersion $siteUrlOfFeatureToBeChecked Write-Host AppendLog "All features updated" "Green" Note: If you have not version your feature explicitly , your feature version will be 0.0.0.0 .

Let me know if you have questions, which ones you find useful, or how you altered these to suit your own needs. Send email to a list of recipient addresses: import-csv users.csv | % { send-email -to $_.email -from [email protected] -subject "Important Email" –message "Hello World!" -server 10.0.1.1 } Show the access control list for a specific Exchange folder: get-imap -server $mymailserver -cred $mycred -folder INBOX.RESUMES –acl Add look and read permissions on an Exchange folder, for a list of accounts pulled from a CSV file: import-csv users.csv | % { set-imap -server -acluser $_.username $mymailserver -cred $mycred -folder INBOX.RESUMES –acl “lr”  } Sync system time with an Internet time server: get-time -server clock.psu.edu –set To remotely sync the time on a set of computers: import-csv computers.csv | % { Invoke-Command -computerName $_.computer -cred $mycred -scriptblock { get-time -server clock.psu.edu –set } } Delete all emails from an Exchange folder that match a certain criteria.  For example, delete all emails from [email protected]: get-imap -server $mailserver –cred $mycred | ? {$_.FromEmail -eq [email protected]} | %{ set-imap -server $mailserver –cred $mycred-message $_.Id -delete } Update Twitter status from PowerShell: get-http –url "http://twitter.com/statuses/update.xml" –cred $mycred -variablename status -variablevalue "Tweeting with NetCmdlets!" A test-path that works over FTP, FTPS (SSL), and SFTP (SSH) connections: get-ftp -server $remoteserver –cred $mycred -path /remote/path/to/checkfor* Don't forget the *.  Also, to use SSL or SSH just add an –ssl or –ssh parameter.

  • SQL SERVER – Display Datetime in Specific Format – SQL in Sixty Seconds #033 – Video

    - by pinaldave
    A very common requirement of developers is to format datetime to their specific need. Every geographic location has different need of the date formats. Some countries follow the standard of mm/dd/yy and some countries as dd/mm/yy. The need of developer changes as geographic location changes. In SQL Server there are various functions to aid this requirement. There is function CAST, which developers have been using for a long time as well function CONVERT which is a more enhanced version of CAST. In the latest version of SQL Server 2012 a new function FORMAT is introduced as well. In this SQL in Sixty Seconds video we cover two different methods to display the datetime in specific format. 1) CONVERT function and 2) FORMAT function. Let me know what you think of this video. Here is the script which is used in the video: -- http://blog.SQLAuthority.com -- SQL Server 2000/2005/2008/2012 onwards -- Datetime SELECT CONVERT(VARCHAR(30),GETDATE()) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),10) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),110) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),5) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),105) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),113) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),114) AS DateConvert; GO -- SQL Server 2012 onwards -- Various format of Datetime SELECT CONVERT(VARCHAR(30),GETDATE(),113) AS DateConvert; SELECT FORMAT ( GETDATE(), 'dd mon yyyy HH:m:ss:mmm', 'en-US' ) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),114) AS DateConvert; SELECT FORMAT ( GETDATE(), 'HH:m:ss:mmm', 'en-US' ) AS DateConvert; GO -- Specific usage of Format function SELECT FORMAT(GETDATE(), N'"Current Time is "dddd MMMM dd, yyyy', 'en-US') AS CurrentTimeString; This video discusses CONVERT and FORMAT in simple manner but the subject is much deeper and there are lots of information to cover along with it. I strongly suggest that you go over related blog posts in next section as there are wealth of knowledge discussed there. Related Tips in SQL in Sixty Seconds: Get Date and Time From Current DateTime – SQL in Sixty Seconds #025 Retrieve – Select Only Date Part From DateTime – Best Practice Get Time in Hour:Minute Format from a Datetime – Get Date Part Only from Datetime DATE and TIME in SQL Server 2008 Function to Round Up Time to Nearest Minutes Interval Get Date Time in Any Format – UDF – User Defined Functions Retrieve – Select Only Date Part From DateTime – Best Practice – Part 2 Difference Between DATETIME and DATETIME2 Saturday Fun Puzzle with SQL Server DATETIME2 and CAST What would you like to see in the next SQL in Sixty Seconds video?

  • Chroot into a 32 bit version of ubuntu from a 64 bit host

    - by Leif Andersen
    I have a piece of software that only runs on 32 bit linux (Xilinx webPack 10.1, apperently it 'has' to be the old version because that's the latest one compatible with their boards), anyway, this version is only compatible with 32 bit linux. So, I head off to this page to see what I can do: https://help.ubuntu.com/community/32bit_and_64bit Of the 4 options (listed at the bottom): I already installed ia32-libs, and it's still not working I could do that one if needed (which I ended up doing). No, I don't want to be working from a vm all of next semester, that would be painful and I'd rather just reinstall my whole computer to a 32 bit os (which I don't want to do). It didn't sound like it was the best option based on what I've seen. So I went off to do #2, and set up a chroot for 32 bit ubuntu. It linked to this tutorial: https://help.ubuntu.com/community/DebootstrapChroot As I'm running ubuntu 10.10 I made the lucid and newer version changes. Which is to say I wrote: [hardy-i386] description=Ubuntu 8.04 Hardy for i386 directory=/srv/chroot/hardy-i386 personality=linux32 root-users=leif type=directory users=leif to /etc/schroot/chroot.d/hardy-i386 (Note though that I did save it once before I had the file properly formatted, I saved the correct version moments later though). I then ran: $ sudo mkdir -p /srv/chroot/hardy_i386 $ sudo debootstrap --variant=buildd --arch i386 hardy /srv/chroot/hardy_i386 http://archive.ubuntu.com/ubuntu/ Then I ran: $ schroot -l And it showed the proper chroot, but then when I ran: $ schroot -c hardy-i386 -u root I got the following error: E: 10mount: error: Directory '/srv/chroot/hardy-i386' does not exist E: 10mount: warning: Mount location /var/lib/schroot/mount/hardy-i386-80359697-2164-4b10-a05a-89b0f497c4f1 no longer exists; skipping unmount E: hardy-i386-80359697-2164-4b10-a05a-89b0f497c4f1: Chroot setup failed: stage=setup-start Can anyone help me figure out what the problem is? Oh, by the way: /srv/chroot/hardy-i386 most certainly exists. I've also tried it replacing all references with hardy to lucid, to no avail. Oh, one more thing, I did set up the chrome os environment a month back or so: http://www.chromium.org/chromium-os/developer-guide and it had me use something with chmod. So, can anyone figure out what the problem is? Thank you.

  • JRockit R28/JRockit Mission Control 4.0 is out!

    - by Marcus Hirt
    The next major release of JRockit is finally out! Here are some highlights: Includes the all new JRockit Flight Recorder – supersedes the old JRockit Runtime Analyser. The new flight recorder is inspired by the “black box” in airplanes. It uses a highly efficient recording engine and thread local buffers to capture data about the runtime and the application running in the JVM. It can be configured to always be on, so that whenever anything “interesting” happens, data can be dumped for some time back. Think of it as your own personal profiling time machine. Automatic shortest path calculation in Memleak – no longer any need for running around in circles when trying to find your way back to a thread root from an instance. Memleak can now show class loader related information and split graphs on a per class loader basis. More easily configured JMX agent – default port for both RMI Registry and RMI Server can be configured, and is by default the same, allowing easier configuration of firewalls. Up to 64 GB (was 4GB) compressed references. Per thread allocation profiling in the Management Console. Native Memory Tracking – it is now possible to track native memory allocations with very high resolution. The information can either be accessed using JRCMD, or the dedicated Native Memory Tracking experimental plug-in for the Management Console (alas only available for the upcoming 4.0.1 release). JRockit can now produce heap dumps in HPROF format. Cooperative suspension – JRockit is no longer using system signals for stopping threads, which could lead to hangs if signals were lost or blocked (for example bad NFS shares). Now threads check periodically to see if they are suspended. VPAT/Section 508 compliant JRMC – greatly improved keyboard navigation and screen reader support. See New and Noteworthy for more information. JRockit Mission Control 4.0.0 can be downloaded from here: http://www.oracle.com/technology/software/products/jrockit/index.html <shameless ad> There is even a book to go with JRMC 4.0.0/JRockit R28! http://www.packtpub.com/oracle-jrockit-the-definitive-guide/book/ </shameless ad>

    When you use the .NET Framework’s String.Equals and String.Compare methods do you use an overloStringComparison enumeration value? If not, you should be because the value provided for that StringComparison argument can have a big impact on the results of your string comparison. The StringComparison enumeration defines values that fall into three different major categories: Culture-sensitive comparison using a specific culture, defaulted to the Thread.CurrentThread.CurrentCulture value (StringComparison.CurrentCulture and StringComparison.CurrentCutlureIgnoreCase) Invariant culture comparison (StringComparison.InvariantCulture and StringComparison.InvariantCultureIgnoreCase) Ordinal (byte-by-byte) comparison of  (StringComparison.Ordinal and StringComparison.OrdinalIgnoreCase) There is a lot of great material available that detail the technical ins and outs of these different string comparison approaches. If you’re at all interested in the topic these two MSDN articles are worth a read: Best Practices For Using Strings in the .NET Framework: http://msdn.microsoft.com/en-us/library/dd465121.aspx How To Compare Strings: http://msdn.microsoft.com/en-us/library/cc165449.aspx Those articles cover the technical details of string comparison well enough that I’m not going to reiterate them here other than to say that the upshot is that you typically want to use the culture-sensitive comparison whenever you’re comparing strings that were entered by or will be displayed to users and the ordinal comparison in nearly all other cases. So where does that leave the invariant culture comparisons? The “Best Practices For Using Strings in the .NET Framework” article has the following to say: “On balance, the invariant culture has very few properties that make it useful for comparison. It does comparison in a linguistically relevant manner, which prevents it from guaranteeing full symbolic equivalence, but it is not the choice for display in any culture. One of the few reasons to use StringComparison.InvariantCulture for comparison is to persist ordered data for a cross-culturally identical display. For example, if a large data file that contains a list of sorted identifiers for display accompanies an application, adding to this list would require an insertion with invariant-style sorting.” I don’t know about you, but I feel like that paragraph is a bit lacking. Are there really any “real world” reasons to use the invariant culture comparison? I think the answer to this question is, “yes”, but in order to understand why we should first think about what the invariant culture comparison really does. The invariant culture comparison is really just a culture-sensitive comparison using a special invariant culture (Michael Kaplan has a great post on the history of the invariant culture on his blog: http://blogs.msdn.com/b/michkap/archive/2004/12/29/344136.aspx). This means that the invariant culture comparison will apply the linguistic customs defined by the invariant culture which are guaranteed not to differ between different machines or execution contexts. This sort of consistently does prove useful if you needed to maintain a list of strings that are sorted in a meaningful and consistent way regardless of the user viewing them or the machine on which they are being viewed. Example: Prototype Names Let’s say that you work for a large multi-national toy company with branch offices in 10 different countries. Each year the company would work on 15-25 new toy prototypes each of which is assigned a “code name” while it is under development. Coming up with fun new code names is a big part of the company culture that everyone really enjoys, so to be fair the CEO of the company spent a lot of time coming up with a prototype naming scheme that would be fun for everyone to participate in, fair to all of the different branch locations, and accessible to all members of the organization regardless of the country they were from and the language that they spoke. Each new prototype will get a code name that begins with a letter following the previously created name using the alphabetical order of the Latin/Roman alphabet. Each new year prototype names would start back at “A”. The country that leads the prototype development effort gets to choose the name in their native language. (An appropriate Romanization system will be used for countries where the primary language is not written in the Latin/Roman alphabet. For example, the Pinyin system could be used for Chinese). To avoid repeating names, a list of all current and past prototype names will be maintained on each branch location’s company intranet site. Assuming that maintaining a single pre-sorted list is not feasible among all of the highly distributed intranet implementations, what string comparison method would you use to sort each year’s list of prototype names so that the list is both meaningful and consistent regardless of the country within which the list is being viewed? Sorting the list with a culture-sensitive comparison using the default configured culture on each country’s intranet server the list would probably work most of the time, but subtle differences between cultures could mean that two different people would see a list that was sorted slightly differently. The CEO wants the prototype names to be a unifying aspect of company culture and is adamant that everyone see the the same list sorted in the same order and there’s no way to guarantee a consistent sort across different cultures using the culture-sensitive string comparison rules. The culture-sensitive sort would produce a meaningful list for the specific user viewing it, but it wouldn’t always be consistent between different users. Sorting with the ordinal comparison would certainly be consistent regardless of the user viewing it, but would it be meaningful? Let’s say that the current year’s prototype name list looks like this: Antílope (Spanish) Babouin (French) Cahoun (Czech) Diamond (English) Flosse (German) If you were to sort this list using ordinal rules you’d end up with: Antílope Babouin Diamond Flosse Cahoun This sort is no good because the entry for “C” appears the bottom of the list after “F”. This is because the Czech entry for the letter “C” makes use of a diacritic (accent mark). The ordinal string comparison does a byte-by-byte comparison of the code points that make up each character in the string and the code point for the “C” with the diacritic mark is higher than any letter without a diacritic mark, which pushes that entry to the bottom of the sorted list. The CEO wants each country to be able to create prototype names in their native language, which means we need to allow for names that might begin with letters that have diacritics, so ordinal sorting kills the meaningfulness of the list. As it turns out, this situation is actually well-suited for the invariant culture comparison. The invariant culture accounts for linguistically relevant factors like the use of diacritics but will provide a consistent sort across all machines that perform the sort. Now that we’ve walked through this example, the following line from the “Best Practices For Using Strings in the .NET Framework” makes a lot more sense: One of the few reasons to use StringComparison.InvariantCulture for comparison is to persist ordered data for a cross-culturally identical display That line describes the prototype name example perfectly: we need a way to persist ordered data for a cross-culturally identical display. While this example is 100% made-up, I think it illustrates that there are indeed real-world situations where the invariant culture comparison is useful.

    whenever try to mount ntfs partition it says Error mounting: mount exited with exit code 1: helper failed with: Unprivileged user can not mount NTFS block devices using the external FUSE library. Either mount the volume as root, or rebuild NTFS-3G with integrated FUSE support and make it setuid root.
