  • Transactions in LINQ to SQL applications

    - by nikolaosk
    In this post I would like to talk about LINQ to SQL and transactions.When I have a LINQ to SQL class I always get asked this question, "How does LINQ treat Transactions?". When we use the DeleteOnSubmit() method or the InsertOnSubmit() method, all of those commands at some point are translated into T-SQL commands and then are executed against the database. All of those commands live in transactions and they follow the basic rules of transaction processing. They do succeed together or fail together...(read more)

  • Parsing Extended Events xml_deadlock_report

    - by Michael Zilberstein
    Jonathan Kehayias and Paul Randall posted more than a year ago great articles on how to monitor historical deadlocks using Extended Events system_health default trace. Both tried to fix on the fly the bug in xml output that caused failures in xml validation. Today I've found out that their version isn't bulletproof either. So here is the fixed one: SELECT CAST ( xest.target_data as XML ) xml_data , * INTO #ring_buffer_data FROM     sys.dm_xe_session_targets xest    INNER...(read more)

  • What kind of things are easy in Haskell and hard in Scala, and vice versa?

    - by Daniel C. Sobral
    There has been some intermingling of Scala and Haskell communities, and I have noticed now and then people commenting on stuff that's supposed to be easy in Haskell and hard and Scala. Less often (maybe because I read Scala questions, not Haskell ones), I see someone mentioning that something in Scala is easier than in Haskell. So. I'd like to know from people who are knowledgeable in both what kind of things are easy in Haskell and hard in Scala, and, conversely, what kind of things are easy in Scala and hard in Haskell.

  • Silverlight Cream for April 03, 2010 -- #829

    - by Dave Campbell
    In this Issue: Scott Marlowe, Nokola, SilverLaw, Brad Abrams, Jeff Wilcox, Jesse Liberty, Alexey Zakharov, ondrejsv, Ward Bell, and David Anson. Shoutouts: Bart Czernicki has a post up about the latest with HTML5: HTML 5 is Born Old - Quake in HTML 5 I was sent a link to shoebox360 a while back and had to sign up to see the Silverlight use, but it does work very nice. I like the panoramic carousel in the viewer: shoebox360 Jeff Handley has a post up on RIA Services - Documentation Guidance and Community Samples... the team is looking for feedback from all of us Shawn Wildermuth posted his My MIX Talks' Source Code Laurent Bugnion posted his Sample code and slides for my TechDays10 (Belgium) talks From SilverlightCream.com: Silverlight to WCF Cross Domain SecurityException Scott Marlowe wrote an article about an often-encountered security exception having to do with cross-domain policies. He details the problem, the response, the solution, and yet another problem/solution associated... good stuff, Scott! Simple Functions for HTML Interop You've seen Nokola's graphic work... how about some HTML Interop from him? He's exposing the code he uses in his work. New Video: ChildWindow Styling - Silverlight 3 SilverLaw has a new video tutorial on Silerlight 3 ChildWindow Styling up - in German - but the video is language-agnostic :) Silverlight 4 + RIA Services - Ready for Business: Exposing WCF (SOAP\WSDL) Services Brad Abrams' continuation in his RIA series is this one demonstrating exposing RIA Services as a Soap\WSDL service Silverlight 4: New parser implementation. New parser features. Jeff Wilcox has a post up highlighting some of the new features in Silverlight 4 such as a new parser implementation with new XAML features. New Video Series – Getting Started With Silverlight Jesse Liberty is starting a new video tutorial series that's going to build out to be a "complete survey of Silverlight programming". The first two are in this post and are Getting Started and Adding Controls to a Silverlight App... looks like good material, Jesse, and all the source is there for the taking as well. Silverlight layout hack: Centered content with fixed maxwidth Alexey Zakharov has a quick tip up on creating centered content with fixed maxwidth. He calls it a dirty trick... looks like code to me :) Silverlight DataForm’s autogenerated fields send empty strings to database ondrejsv points up a problem he had with the Toolkit's DataForm, and his solution to it... with code for all of us following along behind :) DevForce Extensibility With MEF InheritedExport Ward Bell has a post up describing how they got DevForce MEF'd up, and looks like a good post to get you all excited about MEF as well... lots of external links and good info. Tip: Read-only custom DependencyProperties don't exist in Silverlight, but can be closely approximated David Anson's latest Tip is about Read-only custom DependencyProperties in Silverlight -- which strictly is not possible, but he has a code example up that gets close.

  • Visio Forward Engineer Addin for Office 2010

    - by AlbertoFerrari
    Most of my database model are written with Visio. I don’t want to start a digression whether Visio is good or not to build a simple data model: Visio is enogh for my modeling needs and customers love its colours and the ability to open the model with Office when I need to discuss it with them. When I have finished modeling, I generate the database and everything works fine. Nevertheless, Microsoft seems not to like the forward engineer capabilities of Visio.

    ( originally posted on DNNDaily ) So I have been trying to figure out how best to do this blog post for a while now, though I think I will be better off doing it as a series of blog posts rather than one individual one. So this post will be the starting point for the conversion. I will update it with links to the other blog posts in the series as they get created and added. Background (all in my opinion and based on my memory, as inaccurate as that may be) : Back in the early days of ASP.NET there...(read more)

  • SQL Server v.Next (Denali) : Deriving sets using SEQUENCE

    - by AaronBertrand
    One complaint about SEQUENCE is that there is no simple construct such as NEXT (@n) VALUES FOR so that you could get a range of SEQUENCE values as a set. In a previous post about SEQUENCE , I mentioned that to get a range of rows from a sequence, you should use the system stored procedure sys.sp_sequence_get_range . There are some issues with this stored procedure: the parameter names are not easy to memorize; it requires multiple conversions to and from SQL_VARIANT; and, producing a set from the...(read more)

  • Mercurial Conversion from Team Foundation Server

    - by mhawley
    I’m using Twitter. Follow me @matthawley One of my many (almost) daily tasks when working on the CodePlex platform since releasing Mercurial as a supported version control system, is converting projects from Team Foundation Server (TFS) to Mercurial. I'm happy to say that of all the conversions I have done since mid-January, the success rate of migrating full source history is about 95%. To get to this success point, I have had to learn and refine several techniques utilizing a few different tools… (read more)

  • Product Naming Conventions - Does it make sense

    - by NeilHambly
    Maybe it’s just me, but with some of the MS Products being released in 2010 with "2010" in their product name, is the naming of the SQL Server product suite being released with product name that doesn’t make sense, our latest SQL Server Release which is now just about to be released is "SQL Server 2008 R2" My question is do you think this product name is ?

Anyway this database has sat happily on the production server for the past 4 years I guess, we've finally made the upgrade to SQL 2008 and the ASPState database has also been upgraded. It seems most likely that the performance increase of our upgrade tipped the usage of this database into...(read more)

  • Developer’s Life – Disaster Lessons – Notes from the Field #039

    - by Pinal Dave
    [Note from Pinal]: This is a 39th episode of Notes from the Field series. What is the best solution do you have when you encounter a disaster in your organization. Now many of you would answer that in this scenario you would have another standby machine or alternative which you will plug in. Now let me ask second question – What would you do if you as an individual faces disaster?  In this episode of the Notes from the Field series database expert Mike Walsh explains a very crucial issue we face in our career, which is not technical but more to relate to human nature. Read on this may be the best blog post you might read in recent times. Howdy! When it was my turn to share the Notes from the Field last time, I took a departure from my normal technical content to talk about Attitude and Communication.(http://blog.sqlauthority.com/2014/05/08/developers-life-attitude-and-communication-they-can-cause-problems-notes-from-the-field-027/) Pinal said it was a popular topic so I hope he won’t mind if I stick with Professional Development for another of my turns at sharing some information here. Like I said last time, the “soft skills” of the IT world are often just as important – sometimes more important – than the technical skills. As a consultant with Linchpin People – I see so many situations where the professional skills I’ve gained and use are more valuable to clients than knowing the best way to tune a query. Today I want to continue talking about professional development and tell you about the way I almost got myself hit by a train – and why that matters in our day jobs. Sometimes we can learn a lot from disasters. Whether we caused them or someone else did. If you are interested in learning about some of my observations in these lessons you can see more where I talk about lessons from disasters on my blog. For now, though, onto how I almost got my vehicle hit by a train… The Train Crash That Almost Was…. My family and I own a little schoolhouse building about a 10 mile drive away from our house. We use it as a free resource for families in the area that homeschool their children – so they can have some class space. I go up there a lot to check in on the property, to take care of the trash and to do work on the property. On the way there, there is a very small Stop Sign controlled railroad intersection. There is only two small freight trains a day passing there. Actually the same train, making a journey south and then back North. That’s it. This road is a small rural road, barely ever a second car driving in the neighborhood there when I am. The stop sign is pretty much there only for the train crossing. When we first bought the building, I was up there a lot doing renovations on the property. Being familiar with the area, I am also familiar with the train schedule and know the tracks are normally free of trains. So I developed a bad habit. You see, I’d approach the stop sign and slow down as I roll through it. Sometimes I’d do a quick look and come to an “almost” stop there but keep on going. I let my impatience and complacency take over. And that is because most of the time I was going there long after the train was done for the day or in between the runs. This habit became pretty well established after a couple years of driving the route. The behavior reinforced a bit by the success ratio. I saw others doing it as well from the neighborhood when I would happen to be there around the time another car was there. Well. You already know where this ends up by the title and backstory here. A few months ago I came to that little crossing, and I started to do the normal routine. I’d pretty much stopped looking in some respects because of the pattern I’d gotten into.  For some reason I looked and heard and saw the train slowly approaching and slammed on my brakes and stopped. It was an abrupt stop, and it was close. I probably would have made it okay, but I sat there thinking about lessons for IT professionals from the situation once I started breathing again and watched the cars loaded with sand and propane slowly labored down the tracks… Here are Those Lessons… It’s easy to get stuck into a routine – That isn’t always bad. Except when it’s a bad routine. Momentum and inertia are powerful. Once you have a habit and a routine developed – it’s really hard to break that. Make sure you are setting the right routines and habits TODAY. What almost dangerous things are you doing today? How are you almost messing up your production environment today? Stop doing that. Be Deliberate – (Even when you are the only one) – Like I said – a lot of people roll through that stop sign. Perhaps the neighbors or other drivers think “why is he fully stopping and looking… The train only comes two times a day!” – they can think that all they want. Through deliberate actions and forcing myself to pay attention, I will avoid that oops again. Slow down. Take a deep breath. Be Deliberate in your job. Pay attention to the small stuff and go out of your way to be careful. It will save you later. Be Observant – Keep your eyes open. By looking around, observing the situation and understanding what your servers, databases, users and vendors are doing – you’ll notice when something is out of place. But if you don’t know what is normal, if you don’t look to make sure nothing has changed – that train will come and get you. Where can you be more observant? What warning signs are you ignoring in your environment today? In the IT world – trains are everywhere. Projects move fast. Decisions happen fast. Problems turn from a warning sign to a disaster quickly. If you get stuck in a complacent pattern of “Everything is okay, it always has been and always will be” – that’s the time that you will most likely get stuck in a bad situation. Don’t let yourself get complacent, don’t let your team get complacent. That will lead to being proactive. And a proactive environment spends less money on consultants for troubleshooting problems you should have seen ahead of time. You can spend your money and IT budget on improving for your customers.
