  • If You Could Cut Your Meeting Times in ½ Would You?

    - by [email protected]
    By Brian Dayton on April 22, 2010 2:02 PM I know it sounds like a big promise. And what I'm thinking about may not cut a :60 minute meeting into :30 minutes, but it could make meetings and interactions up to 2X more productive. How? Social Media for the Enterprise, Not Social Media In the Enterprise Bear with me. I'm not talking about whether or not workers should or shouldn't have access to Facebook on corporate networks. That topic has been discussed @ length. I'm also not talking about the direct benefits of Social Networking tools like Presence (the ability to see someone online and ask a question in real-time), blogs, RSS feeds or external tools like Twitter. The Un-Measurable Benefits Would you do something that you believe will have a positive effect--but can't be measured? It's impossible to quantify the effectiveness of a meeting. However, what I am talking about would be more of a byproduct of all of the social networking tools above. Here's the hypothesis: As I've gotten more and more busy with work, family, travel and kids--and the same has happened to my friends and family--I'm less and less connected. But by introducing Facebook to my life I've not only made connections with longtime friends whom I haven't spoken to in years--but I've increased the pace and quality of interactions, on and offline, with close friends who I see and speak to every week. In some cases it even enhances the connections and interactions with those I see or speak to every day. The same holds true in an organization. Especially a larger one with highly matrixed organizational structures. You work with people on a project, new people come in with each different project and a disproportionate amount of time is spent getting oriented and staying current. Going back to the initial value proposition--making meetings shorter/more effective--a large amount of time is spent: - At Project Kick-off: Meeting and understanding team member's histories, goals & roles - Ongoing: Summarizing events since the last meeting or update email In my personal, Facebook life today I know that: - My best friend from college - has been stranded in India for 5 days because of the volcano in Iceland and is now only 250 miles from home - One of my co-workers started conference calls at 6:30 this morning - My wife wasn't terribly pleased with my painting skills in our new bathroom (disclosure: she told me this face to face too) Strengthening Weak Links A recent article in CIO Magazine, Three Dangerous Social Media Misconceptions (Kristen Burnham, March 12, 2010) calls out the #1 misconception as follows: 1. "Face-to-face relationships are far more valuable than virtual ones." While some level of physical interaction will always add value to relationships, Gartner says that come 2020, most relationships and teams will be based on "weak links"--that is, you may not have personally met a contact, but you'll know of or may have interacted with him via social sites like Facebook, LinkedIn and Twitter. The sooner your enterprise adopts these tools, the sooner your employees will learn them, and the sooner you'll begin to cultivate these relationships-of-the-future. I personally believe that it's not an either/or choice between face-to-face and virtual interactions. In fact, I'll be as bold as saying it doesn't matter. I can point to two extremely valuable work relationships that I've had over the past 5 years: - I shared an office with one of them - I met the other person, face-to-face, only once Both relationships were very productive. The dynamics were similar. The communication tactics differed immensely. What does matter is the quality, frequency and relevance of interactions. Still sound like too much? An over-promise? Stay tuned for my next post The Gap Between Facebook and LinkedIn. I'll also connect some of the dots with where Oracle Applications and technologies are headed.

  • JustMock and Moles – A short overview for TDD alpha geeks

    - by RoyOsherove
    People have been lurking near my house, asking me to write something about Moles and JustMock, so I’ll try to be as objective as possible, taking in the fact that I work at Typemock. If I were NOT working at Typemock I’d write: JustMock JustMock tries to be Typemock at so many levels it’s not even funny. Technically they work the same and the API almost looks like it’s a search and replace work based on the Isolator API (awesome compliment!), but JustMock still has too many growing pains and bugs to be usable. Also, JustMock is missing alot of the legacy abilities such as Non public faking, faking all types and various other things that are really needed in real legacy code. Biggest thing (in terms of isolation integration) is that it does not integrate with other profilers such as coverage, NCover etc.) When JustMock comes out of beta, I feel that it should cost about half as Isolator costs, as it currently provides about half the abilities. Moles Moles is an addon of Pex and was originally only intended to work within the Pex environment. It started as a research project and now it’s a power-tool for VS (so it’s a separate install) Now it’s it’s own little stubbing framework. It’s not really an Isolation framework in the classic sense, because it does not provide any kind of API built in to verify object interactions. You have to use manual flags all on your own to do that. It generates two types of classes per assembly: Manual Stubs(just like you’d hand code them) and Mole classes. Each Mole class is a special API to change and break the behavior that the corresponding type. so MDateTime is how you change behavior for DateTime. In that sense the API is al over the place, and it can become highly unreadable and unmentionable over time in your test. Also, the Moles API isn’t really designed to deal with real Legacy code. It only deals with public types and methods. anything internal or private is ignored and you can’t change its behavior. You also can’t control static constructors. That takes about 95% of legacy scenarios out of the picture if that’s what you’re trying to use it for. Personally, I found it hard to get used to the idea of two parallel APIs for different abilities, and when to choose which. and I know this stuff. I would expect more usability from the API to make it more widely used. I don’t think that Moles in planning to go that route. Publishing it as an Isolation framework is really an afterthought of a tool that was design with a specific task in mind, and generic Isolation isn’t it. it’s only hope is DEQ – a simple code example that shows a simple Isolation API built on the Moles generic engine. Moles can and should be used for very simple cases of detouring functionality such a simple static methods or interfaces and virtual functions (like rhinomock and MOQ do).   Oh, Wait. Ah, good thing I work at Typemock. I won’t write all that. I’ll just write: JustMock and Moles are great tools that enlarge the market space for isolation related technologies, and they prove that the idea of productivity and unit testing can go hand in hand and get people hooked. I look forward to compete with them at this growing market.

  • Want a headless build server for SSDT without installing Visual Studio? You’re out of luck!

    - by jamiet
    An issue that regularly seems to rear its head on my travels is that of headless build servers for SSDT. What does that mean exactly? Let me give you my interpretation of it. A SQL Server Data Tools (SSDT) project incorporates a build process that will basically parse all of the files within the project and spit out a .dacpac file. Where an organisation employs a Continuous Integration process they will likely want to automate the building of that dacpac whenever someone commits a change to the source control repository. In order to do that the organisation will use a build server (e.g. TFS, TeamCity, Jenkins) and hence that build server requires all the pre-requisite software that understands how to build an SSDT project. The simplest way to install all of those pre-requisites is to install SSDT itself however a lot of folks don’t like that approach because it installs a lot unnecessary components on there, not least Visual Studio itself. Those folks (of which i am one) are of the opinion that it should be unnecessary to install a heavyweight GUI in order to simply get a few software components required to do something that inherently doesn’t even need a GUI. The phrase “headless build server” is often used to describe a build server that doesn’t contain any heavyweight GUI tools such as Visual Studio and is a desirable state for a build server. In his blog post Headless MSBuild Support for SSDT (*.sqlproj) Projects Gert Drapers outlines the steps necessary to obtain a headless build server for SSDT: This article describes how to install the required components to build and publish SQL Server Data Tools projects (*.sqlproj) using MSBuild without installing the full SQL Server Data Tool hosted inside the Visual Studio IDE. http://sqlproj.com/index.php/2012/03/headless-msbuild-support-for-ssdt-sqlproj-projects/ Frankly however going through these steps is a royal PITA and folks like myself have longed for Microsoft to support headless build support for SSDT by providing a distributable installer that installs only the pre-requisites for building SSDT projects. Yesterday in MSDN forum thread Building a VS2013 headless build server - it's sooo hard Mike Hingley complained about this very thing and it prompted a response from Kevin Cunnane from the SSDT product team: The official recommendation from the TFS / Visual Studio team is to install the version of Visual Studio you use on the build machine. I, like many others, would rather not have to install full blown Visual Studio and so I asked: Is there any chance you'll ever support any of these scenarios: Installation of all build/deploy pre-requisites without installing the VS shell? TFS shipping with all of the pre-requisites for doing SSDT project build/deploys 3rd party build servers (e.g. TeamCity) shipping with all of the requisites for doing SSDT project build/deploys I have to say that the lack of a single installer containing all the pre-requisites for SSDT build/deploy puzzles me. Surely the DacFX installer would be a perfect vehicle for that? Kevin replied again: The answer is no for all 3 scenarios. We looked into this issue, discussed it with the Visual Studio / TFS team, and in the end agreed to go with their latest guidance which is to install Visual Studio (e.g. VS2013 Express for Web) on the build machine. This is how Visual Studio Online is doing it and it's the approach recommended for customers setting up their own TFS build servers. I would hope this is compatible with 3rd party build servers but have not verified whether this works with TeamCity etc. Note that DacFx MSI isn't a suitable release vehicle for this as we don't want to include Visual Studio/MSBuild dependencies in that package. It's meant to just include the core DacFx DLLs used by SSMS, SqlPackage.exe on the command line, etc. What this means is we won't be providing a separate MSI installer or nuget package with just the necessary build DLLs you need to run your build and tests. If someone wanted to create a script that generated a nuget package based on our DLLs and targets files, then release that somewhere on the web for easier integration with 3rd party build servers we've no problem with that. Again, here’s the link to the thread and its worth reading in its entirety if this is something that interests you. So there you have it. Microsoft will not be be providing support for headless build servers for SSDT but if someone in the community wants to go ahead and roll their own, go right ahead. @Jamiet

  • Inequality joins, Asynchronous transformations and Lookups : SSIS

    - by jamiet
    It is pretty much accepted by SQL Server Integration Services (SSIS) developers that synchronous transformations are generally quicker than asynchronous transformations (for a description of synchronous and asynchronous transformations go read Asynchronous and synchronous data flow components). Notice I said “generally” and not “always”; there are circumstances where using asynchronous transformations can be beneficial and in this blog post I’ll demonstrate such a scenario, one that is pretty common when building data warehouses. Imagine I have a [Customer] dimension table that manages information about all of my customers as a slowly-changing dimension. If that is a type 2 slowly changing dimension then you will likely have multiple rows per customer in that table. Furthermore you might also have datetime fields that indicate the effective time period of each member record. Here is such a table that contains data for four dimension members {Terry, Max, Henry, Horace}: Notice that we have multiple records per customer and that the [SCDStartDate] of a record is equivalent to the [SCDEndDate] of the record that preceded it (if there was one). (Note that I am on record as saying I am not a fan of this technique of storing an [SCDEndDate] but for the purposes of clarity I have included it here.) Anyway, the idea here is that we will have some incoming data containing [CustomerName] & [EffectiveDate] and we need to use those values to lookup [Customer].[CustomerId]. The logic will be: Lookup a [CustomerId] WHERE [CustomerName]=[CustomerName] AND [SCDStartDate] <= [EffectiveDate] AND [EffectiveDate] <= [SCDEndDate] The conventional approach to this would be to use a full cached lookup but that isn’t an option here because we are using inequality conditions. The obvious next step then is to use a non-cached lookup which enables us to change the SQL statement to use inequality operators: Let’s take a look at the dataflow: Notice these are all synchronous components. This approach works just fine however it does have the limitation that it has to issue a SQL statement against your lookup set for every row thus we can expect the execution time of our dataflow to increase linearly in line with the number of rows in our dataflow; that’s not good. OK, that’s the obvious method. Let’s now look at a different way of achieving this using an asynchronous Merge Join transform coupled with a Conditional Split. I’ve shown it post-execution so that I can include the row counts which help to illustrate what is going on here: Notice that there are more rows output from our Merge Join component than on the input. That is because we are joining on [CustomerName] and, as we know, we have multiple records per [CustomerName] in our lookup set. Notice also that there are two asynchronous components in here (the Sort and the Merge Join). I have embedded a video below that compares the execution times for each of these two methods. The video is just over 8minutes long. View on Vimeo  For those that can’t be bothered watching the video I’ll tell you the results here. The dataflow that used the Lookup transform took 36 seconds whereas the dataflow that used the Merge Join took less than two seconds. An illustration in case it is needed: Pretty conclusive proof that in some scenarios it may be quicker to use an asynchronous component than a synchronous one. Your mileage may of course vary. The scenario outlined here is analogous to performance tuning procedural SQL that uses cursors. It is common to eliminate cursors by converting them to set-based operations and that is effectively what we have done here. Our non-cached lookup is performing a discrete operation for every single row of data, exactly like a cursor does. By eliminating this cursor-in-disguise we have dramatically sped up our dataflow. I hope all of that proves useful. You can download the package that I demonstrated in the video from my SkyDrive at http://cid-550f681dad532637.skydrive.live.com/self.aspx/Public/BlogShare/20100514/20100514%20Lookups%20and%20Merge%20Joins.zip Comments are welcome as always. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Things to install on a new machine – revisited

    - by RoyOsherove
    as I prepare to get a new dev machine at work, I write the things I am going to install on it, before writing the first line of code on that machine: Control Freak Tools: Everything Search Engine – a free and amazingly fast search engine for files all over your machine. (just file names, not inside files). This is so fast I use it almost as a replacement for my start menu, but it’s also great for finding those files that get hidden and tucked away in dark places on my system. Ever had a situation where you needed to see exactly how many copies of X.dll were hiding on your machine and where? this tool is perfect for that. Google Chrome. It’s just fast. very fast. and Firefox has become the IE of alternative browsers in terms of speed and memory. Don’t even get me started on IE. TweetDeck – get a complete view of what’s up on twitter Total Commander – my still favorite file manager, over five years now. KatMouse – will scroll any window your hovering on, even if it’s not an active window, when you use scroll the wheel on it. PowerIso or Daemon Tools – for loading up ISO images of discs LogMeIn Ignition – quick access to your LogMeIn computers for online Backup: JungleDisk or BackBlaze KeePass – save important passwords MS Security Essentials – free anti virus that’s quoest and doesn’t make a mess of your system. for home: uTorrent – a torrent client that can read rss feeds (like the ones from ezrss.it ) Camtasia Studio and SnagIt – for recording and capturing the screen, and then adding cool effects on top. Foxit PDF Reader – much faster that adove reader. Toddler Keys (for home) – for when your baby wants to play with your keyboard. Live Writer – for writing blog posts for Lenovo ThinkPads – Lenovo System Update – if you have a “custom” system instead of the one that came built in, this will keep all your lenovo drivers up to date. FileZilla – for FTP stuff All the utils from sysinternals, (or try the live-links) especially: AutoRuns for deciding what’s really going to load at startup, procmon to see what’s really going on with processes in your system   Developer stuff: Reflector. Pure magic. Time saver. See source code of any compiled assembly. Resharper. Great for productivity and navigation across your source code FinalBuilder – a commercial build automation tool. Love it. much better than any xml based time hog out there. TeamCity – a great visual and friendly server to manage continuous integration. powerful features. Test Lint – a free addin for vs 2010 I helped create, that checks your unit tests for possible problems and hints you about it. TestDriven.NET – a great test runner for vs 2008 and 2010 with some powerful features. VisualSVN – a commercial tool if you use subversion. very reliable addin for vs 2008 and 2010 Beyond Compare – a powerful file and directory comparison tool. I love the fact that you can right click in windows exporer on any file and select “select left side to compare”, then right click on another file and select “compare with left side”. Great usability thought! PostSharp 2.0 – for addind system wide concepts into your code (tracing, exception management). Goes great hand in hand with.. SmartInspect – a powerful framework and viewer for tracing for your application. lots of hidden features. Crypto Obfuscator – a relatively new obfuscation tool for .NET that seems to do the job very well. Crypto Licensing – from the same company –finally a licensing solution that seems to really fit what I needed. And it works. Fiddler 2 – great for debugging and tracing http traffic to and from your app. Debugging Tools for Windows and DebugDiag  - great for debugging scenarios. still wanting more? I think this should keep you busy for a while.   Regulator and Regulazy – for testing and generating regular expressions Notepad 2 – for quick editing and viewing with syntax highlighting

  • SQLAuthority News – The Best Quotes of “Who Wrote This?” Contest

    - by pinaldave
    I am a frequent reader of Brent Ozar PLF, it is one of my favorite blogs. A recent post announced a “Who Wrote This?” contest to see if readers could tell their three contributors apart based on some writing samples. Here are my favorite lines from the sample paragraphs, from each of the three “mystery authors.” Topic 1: Working with Bad Managers Mystery Author A – “Working with bad managers means working against my own happiness, and I’ve come to learn that there’s no changing bad managers.” I love this line because, as anyone who has had a bad manager knows, often a lot of self-doubt rises up. We all have to remember that sometimes the problem is out of our control. Mystery Author B – “Mentor your manager just like you would mentor a junior DBA.” Having a bad manager can be extremely depressing, and we often feel out of control. But we all need to remember that our work is a two-way street, and that sometimes we can subtly influence those above us. Mystery Author C – “The trick to working for all bad managers is to remember that they aren’t your parent. Take charge of your career.” We all also need to learn not to play the blame game. Would you rather stay in a place where you are unhappy, or would you rather take charge of your life? I hope most people would pick the latter. Topic 2: Working with Remote Teams Mystery Author A – “Like almost anything else the key is to make sure that everyone on the team has an understanding of how and when communication will occur.” Communication is so important. I cannot over emphasize how much. And this one line captures how I feel and even communicates the idea clearly! Mystery Author B – “The key to remote team success is verifiable trust: feeling confident that invisible team members are doing the right amount of the right thing at the right time.” I think this line not only captures the key aspects of remote work – verifiable work and trust – but there were so many lines that followed that I loved and could not fit here. The whole paragraph is a list for successful remote work. Everyone could benefit from reading it. Mystery Author C – “What seems clear, precise, and specific in one time zone comes across as vague, soupy, and just plain weird in another.” You know what? I just love this description. The author is right – sometimes vague e-mails really do seem soupy and weird! Topic 3: Working with Your Nemesis Mystery Author A – “Every job is temporary, but your reputation stays with you.” Everyone needs to remember this. The workplace is meant to be a professional arena, and many people have the opinion that work is temporary and disposable. No one wants to work with co-worker like that. Mystery Author B – “Unhealthy conflict is going to lead to leaving three week old tuna fish sandwiches in someone’s desk drawer.” Sometimes humor really is the best policy! Mystery Author C – “Oh no, it’s that guy.” This might seem like a weird phrase to choose as my favorite from an entire paragraph. But the whole piece was written in the form of a story of co-workers getting drunk and plotting against a nemesis. It was too funny to overlook, but too long to post here. A must read!

  • Create Music Playlists in Windows 7 Media Center

    - by DigitalGeekery
    One of the new features in Windows 7 Media Center is the ability to easily create music playlists without using Media Player. Today we’ll take a closer look at how to create them directly in Media Center. Create Manual Playlists Open Windows Media Center and select the Music Library. From within the Music Library, choose playlists from the top menu.   Then select Create Playlist. Give your new playlist a name, and select Next. Choose Music Library and select Next.    Select “songs” from the top menu, choose the songs for your playlist from your library, and select Next when finished. You can also click Select All to add all songs to your playlist, or clear all to remove them. Note: you can also sort by artist, album, genre, etc. from the top menu.   Now you can review and edit your playlist. Click the up and down pointers to move songs up and down in the playlist, or “X” to remove them. You can also go back and add additional songs by selecting Add More. Click Create when you are finished.   Auto Playlists Windows Media Center also allows you to create six different auto playlists. These are dynamic playlists based on pre-defined criteria. Auto Playlists include All Music, Music added in the last month, Music auto rated at 5 stars, Music played in the last month, Music played the most, and Music rated 4 or 5 stars. These Auto Playlists will change dynamically as your library and listening habits change. Your new music playlists can be found under playlists in the music library. Select play playlist to start the music. Now kick back and enjoy the music from your playlist. Conclusion While earlier versions of WMC allowed you to create playlists, you had to do it through Windows Media Player. This is a nice new feature for music lovers who use WMC and prefer to do everything with a remote. Do you already have playlists that you’ve created in Windows Media Player? Windows Media Center can play those too. If your playlists are in the default Music folder, Media Center will detect them automatically and add them to your Music Library. Plus, any playlists you create in Media Center are also available for Media Player. For more on creating Playlists in Media Player, check out our previous articles on how to create a custom playlist in Windows Media Player 12, and how to create auto playlists in WMP 12.

  • How To Clear An Alert - Part 2

    - by werner.de.gruyter
    There were some interesting comments and remarks on the original posting, so I decided to do a follow-up and address some of the issues that got raised... Handling Metric Errors First of all, there is a significant difference between an 'error' and an 'alert'. An 'alert' is the violation of a condition (a threshold) specified for a given metric. That means that the Agent is collecting and gathering the data for the metric, but there is a situation that requires the attention of an administrator. An 'error' on the other hand however, is a failure to collect metric data: The Agent is throwing the error because it cannot determine the value for the metric Whereas the 'alert' guarantees continuity of the metric data, an 'error' signals a big unknown. And the unknown aspect of all this is what makes an error a lot more serious than a regular alert: If you don't know what the current state of affairs is, there could be some serious issues brewing that nobody is aware of... The life-cycle of a Metric Error Clearing a metric error is pretty much the same workflow as a metric 'alert': The Agent signals the error after it failed to execute the metric The error is uploaded to the OMS/repository, where it becomes visible in the Console The error will remain active until the Agent is able to execute the metric successfully. Even though the metric is still getting scheduled and executed on a regular basis, the error will remain outstanding as long as the Agent is not capable of executing the metric correctly Knowing this, the way to fix the metric error should be obvious: Take the 'problem' away, and as soon as the metric is executed again (based on the frequency of the metric), the error will go away. The same tricks used to clear alerts can be used here too: Wait for the next scheduled execution. For those metrics that are executed regularly (like every 15 minutes or so), it's just a matter of waiting those minutes to see the updates. The 'Reevaluate Alert' button can be used to force a re-execution of the metric. In case a metric is executed once a day, this will be a better way to make sure that the underlying problem has been solved. And if it has been, the metric error will be removed, and the regular data points will be uploaded to the repository. And just in case you have to 'force' the issue a little: If you disable and re-enable a metric, it will get re-scheduled. And that means a new metric execution, and an update of the (hopefully) fixed problem. Database server-generated alerts and problem checkers There are various ways the Agent can collect metric data: Via a script or a SQL statement, reading a log file, getting a value from an SNMP OID or listening for SNMP traps or via the DBMS_SERVER_ALERTS mechanism of an Oracle database. For those alert which are generated by the database (like tablespace metrics for 10g and above databases), the Agent just 'waits' for the database to report any new findings. If the Agent has lost the current state of the server-side metrics (due to an incomplete recovery after a disaster, or after an improper use of the 'emctl clearstate' command), the Agent might be still aware of an alert that the database no longer has (or vice versa). The same goes for 'problem checker' alerts: Those metrics that only report data if there is a problem (like the 'invalid objects' metric) will also have a problem if the Agent state has been tampered with (again, the incomplete recovery, and after improper use of 'emctl clearstate' are the two main causes for this). The best way to deal with these kinds of mismatches, is to simple disable and re-enable the metric again: The disabling will clear the state of the metric, and the re-enabling will force a re-execution of the metric, so the new and updated results can get uploaded to the repository. Starting 10gR5, the Agent performs additional checks and verifications after each restart of the Agent and/or each state change of the database (shutdown/startup or failover in case of DataGuard) to catch these kinds of mismatches.

  • Beware when using .NET's named pipes in a windows forms application

    - by FransBouma
    Yesterday a user of our .net ORM Profiler tool reported that he couldn't get the snapshot recording from code feature working in a windows forms application. Snapshot recording in code means you start recording profile data from within the profiled application, and after you're done you save the snapshot as a file which you can open in the profiler UI. When using a console application it worked, but when a windows forms application was used, the snapshot was always empty: nothing was recorded. Obviously, I wondered why that was, and debugged a little. Here's an example piece of code to record the snapshot. This piece of code works OK in a console application, but results in an empty snapshot in a windows forms application: var snapshot = new Snapshot(); snapshot.Record(); using(var ctx = new ORMProfilerTestDataContext()) { var customers = ctx.Customers.Where(c => c.Country == "USA").ToList(); } InterceptorCore.Flush(); snapshot.Stop(); string error=string.Empty; if(!snapshot.IsEmpty) { snapshot.SaveToFile(@"c:\temp\generatortest\test2\blaat.opsnapshot", out error); } if(!string.IsNullOrEmpty(error)) { Console.WriteLine("Save error: {0}", error); } (the Console.WriteLine doesn't do anything in a windows forms application, but you get the idea). ORM Profiler uses named pipes: the interceptor (referenced and initialized in your application, the application to profile) sends data over the named pipe to a listener, which when receiving a piece of data begins reading it, asynchronically, and when properly read, it will signal observers that new data has arrived so they can store it in a repository. In this case, the snapshot will be the observer and will store the data in its own repository. The reason the above code doesn't work in windows forms is because windows forms is a wrapper around Win32 and its WM_* message based system. Named pipes in .NET are wrappers around Windows named pipes which also work with WM_* messages. Even though we use BeginRead() on the named pipe (which spawns a thread to read the data from the named pipe), nothing is received by the named pipe in the windows forms application, because it doesn't handle the WM_* messages in its message queue till after the method is over, as the message pump of a windows forms application is handled by the only thread of the windows forms application, so it will handle WM_* messages when the application idles. The fix is easy though: add Application.DoEvents(); right before snapshot.Stop(). Application.DoEvents() forces the windows forms application to process all WM_* messages in its message queue at that moment: all messages for the named pipe are then handled, the .NET code of the named pipe wrapper will react on that and the whole process will complete as if nothing happened. It's not that simple to just say 'why didn't you use a worker thread to create the snapshot here?', because a thread doesn't get its own message pump: the messages would still be posted to the window's message pump. A hidden form would create its own message pump, so the additional thread should also create a window to get the WM_* messages of the named pipe posted to a different message pump than the one of the main window. This WM_* messages pain is not something you want to be confronted with when using .NET and its libraries. Unfortunately, the way they're implemented, a lot of APIs are leaky abstractions, they bleed the characteristics of the OS objects they hide away through to the .NET code. Be aware of that fact when using them :)

  • FluentPath: a fluent wrapper around System.IO

    - by Bertrand Le Roy
    .NET is now more than eight years old, and some of its APIs got old with more grace than others. System.IO in particular has always been a little awkward. It’s mostly static method calls (Path.*, Directory.*, etc.) and some stateful classes (DirectoryInfo, FileInfo). In these APIs, paths are plain strings. Since .NET v1, lots of good things happened to C#: lambda expressions, extension methods, optional parameters to name just a few. Outside of .NET, other interesting things happened as well. For example, you might have heard about this JavaScript library that had some success introducing a fluent API to handle the hierarchical structure of the HTML DOM. You know? jQuery. Knowing all that, every time I need to use the stuff in System.IO, I cringe. So I thought I’d just build a more modern wrapper around it. I used a fluent API based on an essentially immutable Path type and an enumeration of such path objects. To achieve the fluent style, a healthy dose of lambda expressions is being used to act on the objects. Without further ado, here’s an example of what you can do with the new API. In that example, I’m using a Media Center extension that wants all video files to be in their own folder. For that, I need a small tool that creates directories for each video file and moves the files in there. Here’s the code for it: Path.Get(args[0]) .Select(p => p.Extension == ".avi" || p.Extension == ".m4v" || p.Extension == ".wmv" || p.Extension == ".mp4" || p.Extension == ".dvr-ms" || p.Extension == ".mpg" || p.Extension == ".mkv") .CreateDirectory(p => p.Parent .Combine(p.FileNameWithoutExtension)) .Previous() .Move(p => p.Parent .Combine(p.FileNameWithoutExtension) .Combine(p.FileName)); This code creates a Path object pointing at the path pointed to by the first command line argument of my executable. It then selects all video files. After that, it creates directories that have the same names as each of the files, but without their extension. The result of that operation is the set of created directories. We can now get back to the previous set using the Previous method, and finally we can move each of the files in the set to the corresponding freshly created directory, whose name is the combination of the parent directory and the filename without extension. The new fluent path library covers a fair part of what’s in System.IO in a single, convenient API. Check it out, I hope you’ll enjoy it. Suggestions are more than welcome. For example, should I make this its own project on CodePlex or is this informal style just OK? Anything missing that you’d like to see? Is there a specific example you’d like to see expressed with the new API? Bugs?

  • Christian Radio Locator iPhone app

    - by Tim Hibbard
    For the last three months or so I've been working on an iPhone (and iPad) app in my spare time. It all started when I took the kids to Minneapolis and had a hard time finding radio stations to listen to on the trip. I looked in the App Store for an app that would use my GPS to show me Christian radio stations nearby, but there wasn't one. So I decided to build my own. Using public information from the FCC and a few other sources, I built a database in Google docs that contains the frequency for all Christian radio stations, where the tower is located and how far the tower can reach. I also included any streaming audio information and other contact information like Facebook or Twitter that I could find. Google spreadsheets publish in JSON format (yes, really) and Xcode can automatically deserialize JSON into a properly formatted entity. This is one area that Xcode is far superior to C#. In a just a few lines of code, I can have a list of in-memory strongly typed objects from a web-based JSON feed. To accomplish the same thing natively in .NET would be much more work and wouldn't feel nearly as clean when it was said and done. The snazzy icon shown above was built by my very talented wife. She hasn't yet provided any feedback on the app's user interface, which is why it is so plain and boring. I used a navigation view controller and EGO pull to refresh table view to construct the main window. Pulling down to refresh initiates a GPS lookup, which queries the database for radio stations in range (yes, you can pass parameters to Google spreadsheets and get a subset back in JSON). Pulling up on the table extends the range of the search and includes stations that may not be close enough to get clear audio. This feature is not that intuitive and the next version contains an update to that functionality. Tapping a cell will show a detail view that displays additional information about the station. The user can click to view the station on a map, click to listen to an online stream (if available) or click to see the station's Facebook or Twitter pages. Swiping back and forth on the table changes the information that is displayed on the right hand side of the table cell. It scrolls through the city where the tower is located, how far the phone is from the tower, the range of the tower and in the next version a signal strength indicator. This was pretty easy to implement once I figured out how to assign the gesture recognizer delegate.  Tapping and holding on a cell will jump the user to the map view screen. Which is pretty cool, but very hard for even a power user to discover. To tackle the issue of discoverability, the next version has a series of instructions displayed at the bottom of the screen to show the user the various shortcuts. Once the user has performed the swipes and long holds, the instructions disappear. I've learned a lot developing this app. Spending over a decade exclusively in .NET made the learning curve a bit steep, but once I learned the structure and syntax of Objective-C, I've learned to appreciate the power and simplicity of it. Here are a few screenshots. I would really appreciate any feedback and especially iTunes reviews. Technically it is open source and a smart googler could probably find it. I just haven't promoted it as open source.     Cross posted from timhibbard.com

  • Collation errors in business

    - by Rob Farley
    At the PASS Summit last month, I did a set (Lightning Talk) about collation, and in particular, the difference between the “English” spoken by people from the US, Australia and the UK. One of the examples I gave was that in the US drivers might stop for gas, whereas in Australia, they just open the window a little. This is what’s known as a paraprosdokian, where you suddenly realise you misunderstood the first part of the sentence, based on what was said in the second. My current favourite is Emo Phillip’s line “I like to play chess with old men in the park, but it can be hard to find thirty-two of them.” Essentially, this a collation error, one that good comedians can get mileage from. Unfortunately, collation is at its worst when we have a computer comparing two things in different collations. They might look the same, and sound the same, but if one of the things is in SQL English, and the other one is in Windows English, the poor database server (with no sense of humour) will get suspicious of developers (who all have senses of humour, obviously), and declare a collation error, worried that it might not realise some nuance of the language. One example is the common scenario of a case-sensitive collation and a case-insensitive one. One may think that “Rob” and “rob” are the same, but the other might not. Clearly one of them is my name, and the other is a verb which means to steal (people called “Nick” have the same problem, of course), but I have no idea whether “Rob” and “rob” should be considered the same or not – it depends on the collation. I told a lie before – collation isn’t at its worst in the computer world, because the computer has the sense to complain about the collation issue. People don’t. People will say something, with their own understanding of what they mean. Other people will listen, and apply their own collation to it. I remember when someone was asking me about a situation which had annoyed me. They asked if I was ‘pissed’, and I said yes. I meant that I was annoyed, but they were asking if I’d been drinking. It took a moment for us to realise the misunderstanding. In business, the problem is escalated. A business user may explain something in a particular way, using terminology that they understand, but using words that mean something else to a technical person. I remember a situation with a checkbox on a form (back in VB6 days from memory). It was used to indicate that something was approved, and indicated whether a particular database field should store True or False – nothing more. However, the client understood it to mean that an entire workflow system would be implemented, with different users have permission to approve items and more. The project manager I’d just taken over from clearly hadn’t appreciated that, and I faced a situation of explaining the misunderstanding to the client. Lots of fun... Collation errors aren’t just a database setting that you can ignore. You need to remember that Americans speak a different type of English to Aussies and Poms, and techies speak a different language to their clients.

  • Collaborate10 &ndash; THEconference

    - by jean-pierre.dijcks
    After spending a few days in Mandalay Bay's THEHotel, I guess I now call everything THE... Seriously, they even tag their toilet paper with THEtp... I guess the brand builders in Vegas thought that once you are on to something you keep on doing it, and granted it is a nice hotel with nice rooms. THEanalytics Most of my collab10 experience was in a room called Reef C, where the BIWA bootcamp was held. Two solid days of BI, Warehousing and Analytics organized by the BIWA SIG at IOUG. Didn't get to see all sessions, but what struck me was the high interest in Analytics. Marty Gubar's OLAP session was full and he did some very nice things with the OLAP option. The cool bit was that he actually gets all the advanced calculations in OLAP to show up in OBI EE without any effort. It was nice to see that the idea from OWB where you generate an RPD is now also in AWM. I think it makes life so much simpler to generate these RPD's from your data model. Even if the end RPD needs some tweaking, it is all a lot less effort to get something going. You can see this stuff for yourself in this demo (click here). OBI EE uses just SQL to get to the calculations, and so, if you prefer APEX, you can build you application there and get the same nice calculations in an APEX application. Marty also showed the Simba MDX driver used with Excel. I guess we should call that THEcoolone... and it is very slick and wonderfully useful for all of you who actually know Excel. The nice thing is that you leverage pure Excel for all operations (no plug-ins). That means no new tools to learn, no new controls, all just pure Excel. THEdatabasemachine Got some very good questions in my "what makes Exadata fast" session and overall, the interest in Exadata is overwhelming. One of the things that I did try to do in my session is to get people to think in new patterns rather than in patterns based on Oracle 9i running on some random hardware configuration. We talked a little bit about the often over-indexing and how everyone has to unlearn all of that on Exadata. The main thing however is that everyone needs to get used to the shear size of some of the components in a Database machine V2. 5TB of flash cache is a lot of very fast data storage, half a TB of memory gets quite interesting as well. So what I did there was really focus on some of the content in these earlier posts on Upward ILM and In-Memory processing. In short, I do believe the these newer media point out a trend. In-memory and other fast media will get cheaper and will see more use. Some of that we do automatically by adding new functionality, but in some cases I think the end user of the system needs to start thinking about how to leverage all this new hardware. I think most people got very excited about these new capabilities and opportunities. THEcoolkids One of the cool things about the BIWA track was the hand-on track. Very cool to see big crowds for both OLAP and OWB hands-on. Also quite nice to see that the folks at RittmanMead spent so much time on preparing for that session. While all of them put down cool stuff, none was more cool that seeing Data Mining on an Apple iPAD... it all just looks great on an iPAD! Very disappointing to see that Mark Rittman still wasn't showing OWB on his iPAD ;-) THEend All in all this was a great set of sessions in the BIWA track. Lots of value to our guests (we hope) and we hope they all come again next year!

  • Customize Team Build 2010 – Part 12: How to debug my custom activities

    In the series the following parts have been published Part 1: Introduction Part 2: Add arguments and variables Part 3: Use more complex arguments Part 4: Create your own activity Part 5: Increase AssemblyVersion Part 6: Use custom type for an argument Part 7: How is the custom assembly found Part 8: Send information to the build log Part 9: Impersonate activities (run under other credentials) Part 10: Include Version Number in the Build Number Part 11: Speed up opening my build process template Part 12: How to debug my custom activities Part 13: Get control over the Build Output Part 14: Execute a PowerShell script Part 15: Fail a build based on the exit code of a console application       Developers are “spoilt” persons who expect to be able to have easy debugging experiences for every technique they work with. So they also expect it when developing custom activities for the build process template. This post describes how you can debug your custom activities without having to develop on the build server itself. Remote debugging prerequisites The prerequisite for these steps are to install the Microsoft Visual Studio Remote Debugging Monitor. You can find information how to install this at http://msdn.microsoft.com/en-us/library/bt727f1t.aspx. I chose for the option to run the remote debugger on the build server from a file share. Debugging symbols prerequisites To be able to start the debugging, you need to have the pdb files on the buildserver together with the assembly. The pdb must have been build with Full Debug Info. Steps In my setup I have a development machine and a build server. To setup the remote debugging, I performed the following steps Locate on your development machine the folder C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger Create a share for the Remote Debugger folder. Make sure that the share (and the folder) has the correct permissions so the user on the build server has access to the share. On the build server go to the shared “Remote Debugger” folder Start msvsmon.exe which is located in the folder that represents the platform of the build server. This will open a winform application like   Go back to your development machine and open the BuildProcess solution. Start the Attach to process command (Ctrl+Alt+P) Type in the Qualifier the name of the build server. In my case the user account that has started the msvsmon is another user then the user on my development machine. In that case you have to type the qualifier in the format that is shown in the Remote Debugging Monitor (in my case LOCAL\Administrator@TFSLAB) and confirm it by pressing <Enter> Since the build service is running with other credentials, check the option “Show processes from all users”. Now the Attach to process dialog shows the TFSBuildServiceHost process Set the breakpoint in the activity you want to debug and kick of a build. Be aware that when you attach to the TFSBuildServiceHost that you debug every single build that is run by this windows service, so make sure you don’t debug the build server that is in production! You can download the full solution at BuildProcess.zip. It will include the sources of every part and will continue to evolve.

  • jQuery Context Menu Plugin and Capturing Right-Click

    - by Ben Griswold
    I was thrilled to find Cory LaViska’s jQuery Context Menu Plugin a few months ago. In very little time, I was able to integrate the context menu with the jQuery Treeview.  I quickly had a really pretty user interface which took full advantage of limited real estate.  And guess what.  As promised, the plugin worked in Chrome, Safari 3, IE 6/7/8, Firefox 2/3 and Opera 9.5.  Everything was perfect and I shipped to the Integration Environment. One thing kept bugging though – right clicks aren’t the standard in a web environment. Sure, when one hovers over the treeview node, the mouse changed from an arrow to a pointer, but without help text most users will certainly left-click rather than right. As I was already doubting the design decision, we did some Mac testing.  The context menu worked in Firefox but not Safari.  Damn.  That’s when I started digging into the Madness of Javascript Mouse Events.  Don’t tell, but it’s complicated.  About as close as one can get to capture the right-click mouse event on all major browsers on Windows and Mac is this: if (event.which == null) /* IE case */ button= (event.button < 2) ? "LEFT" : ((event.button == 4) ? "MIDDLE" : "RIGHT"); else /* All others */ button= (event.which < 2) ? "LEFT" : ((event.which == 2) ? "MIDDLE" : "RIGHT"); Yikes.  The content menu code was simply checking if event.button == 2.  No problem.  Cory offers a jQuery Right Click Plugin which I’m sure works for windows but probably not the Mac either.  (Please note I haven’t verified this.) Anyway, I decided to address my UI design concern and the Safari Mac issue in one swoop.  I decided to make the context menu respond to any mouse click event.  This didn’t take much – especially after seeing how Bill Beckelman updated the library to recognize the left click. First, I added an AnyClick option to the library defaults: // Any click may trigger the dropdown and that's okay // See Javascript Madness: Mouse Events – http: //unixpapa.com/js/mouse.html if (o.anyClick == undefined) o.anyClick = false; And then I trigger the context menu dropdown based on the following conditional: if (evt.button == 2 || o.anyClick) { Nothing tricky about that, right?  Finally, I updated my menu setup to include the AnyClick value, if true: $('.member').contextMenu({ menu: 'memberContextMenu', anyClick: true },             function (action, el, pos) {                 … Now the context menu works in “all” environments if you left, right or even middle click.  Download jQuery Context Menu Plugin for Any Click *Opera 9.5 has an option to allow scripts to detect right-clicks, but it is disabled by default. Furthermore, Opera still doesn’t allow JavaScript to disable the browser’s default context menu which causes a usability conflict.

Big Data with CEP and SOA - September 25, 2012 - 14:15 Speaker: Markus Zirn, Oracle and Baz Kuthi, Avocent The "Big Data" trend is driving new kinds of IT projects that process machine-generated data. Such projects store and mine using Hadoop/ Map Reduce, but they also analyze streaming data via event-driven patterns, which can be called "Fast Data" complementary to "Big Data". This session highlights how "Big Data" and "Fast Data" design patterns can be combined with SOA design principles into modern, event-driven architectures. We will describe specific architectures that combines CEP, Distributed Caching, Event-driven Network, SOA Composites, Application Development Framework, as well as Hadoop. Architecture patterns include pre-processing and filtering event streams as close as possible to the event source, in memory master data for event pattern matching, event-driven user interfaces as well as distributed event processing. Focus is on how "Fast Data" requirements are elegantly integrated into a traditional SOA architecture. Markus Zirn is Vice President of Product Management covering Oracle SOA Suite, SOA Governance, Application Integration Architecture, BPM, BPM Solutions, Complex Event Processing and UPK, an end user learning solution. He is the author of “The BPEL Cookbook” (rated best book on Services Oriented Architecture in 2007) as well as “Fusion Middleware Patterns”.

  • ASP.NET MVC for the php/asp noob

    - by dotjosh
    I was talking to a friend today, who's foremost a php developer, about his thoughts on Umbraco and he said "Well they're apparently working feverishly on the new version of Umbraco, which will be MVC... which i still don't know what that means, but I know you like it." I ended up giving him a ground up explanation of ASP.NET MVC, so I'm posting this so he can link this to his friends and for anyone else who finds it useful.  The whole goal was to be as simple as possible, not being focused on proper syntax. Model-View-Controller (or MVC) is just a pattern that is used for handling UI interaction with your backend.  In a typical web app, you can imagine the *M*odel as your database model, the *V*iew as your HTML page, and the *C*ontroller as the class inbetween.  MVC handles your web request different than your typical php/asp app.In your php/asp app, your url maps directly to a php/asp file that contains html, mixed with database access code and redirects.In an MVC app, your url route is mapped to a method on a class (the controller).  The body of this method can do some database access and THEN decide which *V*iew (html/aspx page) should be displayed;  putting the controller in charge and not the view... a clear seperation of concerns that provides better reusibility and generally promotes cleaner code. Mysite.com, a quick example:Let's say you hit the following url in your application: http://www.mysite.com/Product/ShowItem?Id=4 To avoid tedious configuration, MVC uses a lot of conventions by default. For instance, the above url in your app would automatically make MVC search for a .net class with the name "Product" and a method named "ShowItem" based on the pattern of the url.  So if you name things properly, your method would automatically be called when you entered the above url.  Additionally, it would automatically map/hydrate the "int id" parameter that was in your querystring, matched by name.Product.cspublic class Product : Controller{    public ViewResult ShowItem(int id)    {        return View();    }} From this point you can write the code in the body of this method to do some database access and then pass a "bag" (also known as the ViewData) of data to your chosen *V*iew (html page) to use for display.  The view(html) ONLY needs to be worried about displaying the flattened data that it's been given in the best way it can;  this allows the view to be reused throughout your application as *just* a view, and not be coupled to HOW the data for that view get's loaded.. Product.cspublic class Product : Controller{    public ViewResult ShowItem(int id)    {        var database = new Database();        var item = database.GetItem(id);        ViewData["TheItem"] = item;        return View();    }} Again by convention, since the class' method name is "ShowItem", it'll search for a view named "ShowItem.aspx" by default, and pass the ViewData bag to it to use. ShowItem.aspx<html>     <body>      <%        var item =(Item)ViewData["TheItem"]       %>       <h1><%= item.FullProductName %></h1>     </body></html> BUT WAIT! WHY DOES MICROSOFT HAVE TO DO THINGS SO DIFFERENTLY!?They aren't... here are some other frameworks you may have heard of that use the same pattern in a their own way: Ruby On Rails Grails Spring MVC Struts Django

  • How to Install Oracle Software on Remote Linux Server

    - by James Taylor
    It is becoming more common these days to install Oracle software on remote Linux servers. This issue has always existed but was generally resolved either by silent installs or by someone physically going to the server to install the software. This is becoming more difficult with the popular virtualisation and cloud deployment strategies. This post provides the steps involved to install Oracle Software using the GUI interface on a remote Linux server. There are many ways to achieve this, the way I resolve this issue is via Virtual Network Computing (VNC) as it is shipped with RedHat and OEL out of the box. For this post I’m using OEL 5 deployed on a OVM guest. If not already done so download and install a client version of VNC so you can connect to the server. There are many out there, for the purpose of this post I use UltraVNC. You can download a free version from http://www.uvnc.com/download/index.html By default VNC Server is installed in your RedHat and OEL OS, but it is not configured. The way VNC works is when started it creates a client instance for the user and binds it to a specific port. So if have an account on the Linux box you can setup a VNC Server session for that user, you don’t need to be root. For the purpose of this document I’m going to use oracle as the user to setup a VNC Session as this is the user I want use to install the software. However to start the VNC Service you must be root. As the root user run the following command: service vncserver start Starting VNC server: no displays configured                [  OK  ] Login to the Linux box as the user  you wan to install the Oracle software [oracle@lisa ~]$ Run the command to create a new VNC server instance for the oracle user: vncserver You will be ask to supply password information. This is what you will enter when connecting from your desktop client. This password is also independent of the actual Linux user password. The VNC Server is acting as a proxy to this instance. You will require a password to access your desktops. Password: Verify: xauth:  creating new authority file /home/oracle/.Xauthority New 'lisa.nz.oracle.com:1 (oracle)' desktop is lisa.nz.oracle.com:1 Creating default startup script /home/oracle/.vnc/xstartup Starting applications specified in /home/oracle/.vnc/xstartup Log file is /home/oracle/.vnc/lisa.nz.oracle.com:1.log As you can see a new instance lisa.nz.oracle.com:1 has been created. If you were to run the vncserver command again another instance lisa.nz.oracle.com:2 will be created. If you are going through a firewall you will need to ensure that the port 5901 (port 1) is open between your client desktop and the Linux Server. Depending on the options chosen at install time a firewall could be in place. The simplest way to disable this is using the command. You will need to be root. service iptables stop This will stop the firewall while you install. If you just want to add a port to the accepted lists use the firewall UI. You will need to be root. system-config-security-level Now you are ready to connect to the server via the VNC. Using the software installed in step one start the VNC Client. You should be prompted for the server and port. If connectivity is established, you will be prompted for the password entered in step 5. You should now be presented with a terminal screen ready to install software Go to the location of the oracle install software and start the Oracle Universal Installer

  • What's new in ASP.Net 4.5 and VS 2012 - part 2

    - by nikolaosk
    This is the second post in a series of posts titled "What's new in ASP.Net 4.5 and VS 2012".You can have a look at the first post in this series, here. Please find all my posts regarding VS 2012, here. In this post I will be looking into the various new features available in ASP.Net 4.5 and VS 2012.I will be looking into the enhancements in the HTML Editor,CSS Editor and Javascript Editor.In order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 2012 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine.I will work fine in Windows 7 as well so do not worry if you do not have the latest Microsoft operating system.1) Launch VS 2012 and create a new Web Forms application by going to File - >New Web Site - > ASP.Net Web Forms Site.2) Choose an appropriate name for your web site.3) I would like to point out the new enhancements in the CSS editor in VS 2012. In the Solution Explorer in the Content folder and open the Site.cssThen when I try to change the background-color property of the html element, I get a brand new handy color-picker. Have a look at the picture below  Please note that the color-picker shows all the colors that have been used in this website. Then you can expand the color-picker by clicking on the arrows. Opacity is also supported. Have a look at the picture below4) There are also mobile styles in the Site.css .These are based on media queries.Please have a look at another post of mine on CSS3 media queries. Have a look at the picture below In this case when the maximum width of the screen is less than 850px there will be a new layout that will be dictated by these new rules. Also CSS snippets are supported. Have a look at the picture below I am writing a new CSS rule for an image element. I write the property transform and hit tab and then I have cross-browser CSS handling all of the major vendors.Then I simply add the value rotate and it is applied to all the cross browser options.Have a look at the picture below.  I am sure you realise how productive you can become with all these CSS snippets. 5) Now let's have a look at the new HTML editor enhancements in VS 2012You can drag and drop a GridView web server control from the Toolbox in the Site.master file.You will see a smart tag (that was only available in the Design View) that you can expand and add fields, format the web server control.Have a look at the picture below 6) We also have available code snippets. I type <video and then press tab twice.By doing that I have the rest of the HTML 5 markup completed.Have a look at the picture below 7) I have new support for the input tag including all the HTML 5 types and all the new accessibility features.Have a look at the picture below   8) Another interesting feature is the new Intellisense capabilities. When I change the DocType to 4.01 and the type <audio>,<video> HTML 5 tags, Intellisense does not recognise them and add squiggly lines.Have a look at the picture below All these features support ASP.Net Web forms, ASP.Net MVC applications and Web Pages. 9) Finally I would like to show you the enhanced support that we have for Javascript in VS 2012. I have full Intellisense support and code snippets support.I create a sample javascript file. I type If and press tab. I type while and press tab.I type for and press tab.In all three cases code snippet support kicks in and completes the code stack. Have a look at the picture below We also have full Intellisense support.Have a look at the picture below I am creating a simple function and then type some sort of XML like comments for the input parameters. Have a look at the picture below. Then when I call this function, Intellisense has picked up the XML comments and shows the variables data types.Have a look at the picture below Hope it helps!!!

  • Is Agile the new micromanagement?

    - by Smith James
    This question has been cooking in my head for a while so I wanted to ask those who are following agile/scrum practices in their development environments. My company has finally ventured into incorporating agile practices and has started out with a team of 4 developers in an agile group on a trial basis. It has been 4 months with 3 iterations and they continue to do it without going fully agile for the rest of us. This is due to the fact that management's trust to meet business requirements with a quite a bit of ad hoc type request from high above. Recently, I talked to the developers who are part of this initiative; they tell me that it's not fun. They are not allowed to talk to other developers by their Scrum master and are not allowed to take any phone calls in the work area (which maybe fine to an extent). For example, if I want to talk to my friend for kicks who is in the agile team, I am not allowed without the approval of the Scrum master; who is sitting right next to the agile team. The idea of all this or the agile is to provide a complete vacuum for agile developers from any interruptions and to have them put in good 6+ productive hours. Well, guys, I am no agile guru but what I have read Yahoo agile rollout document and similar for other organizations, it gives me a feeling that agile is not cheap. It require resources and budget to instill agile into the teams and correct issue as they arrive to put them back on track. For starters, it requires training for developers and coaching for managers and etc, etc... The current Scrum master was a manager who took a couple days agile training class paid by the management is now leading this agile team. I have also heard in the meeting that agile manifesto doesn't dictate that agile is not set in stones and is customized differently for each company. Well, it all sounds good and reason. In conclusion, I always thought the agile was supposed to bring harmony in the development teams which results in happy developers. However, I am getting a very opposite feeling when talking to the developers in the agile team. They are unhappy that they cannot talk anything but work, sitting quietly all day just working, and they feel it's just another way for management to make them work more. Tell me please, if this is one of the examples of good practices used for the purpose of selfish advantage for more dollars? Or maybe, it's just us the developers like me and this agile team feels that they don't like to work in an environment where they only breathe work because they are at work. Thanks. Edit: It's a company in healthcare domain that has offices across US. It definitely feels like a cowboy style agile which makes me really not wanting to go for agile at all, esp at my current company. All of it has to do with the management being completely cheap. Cutting out expensive coffee for cheaper version, emphasis on savings and being productive while staying as lean as possible. My feeling is that someone in the management behind the door threw out this idea, that agile makes you produce more so we can show our bosses we're producing more with the same headcount. Or, maybe, it will allow us to reduce headcount if that's the case. EDITED: They are having their 5 min daily meeting. But not allowed to chat or talk with someone outside of their team. All focus is on work.

  • From the Tips Box: Pre-installation Prep Work Makes Service Pack Upgrades Smoother

    - by Jason Fitzpatrick
    Last month Microsoft rolled out Windows 7 Service Pack 1 and, like many SP releases, quite a few people are hanging back to see what happens. If you want to update but still error on the side of caution, reader Ron Troy  offers a step-by-step guide. Ron’s cautious approach does an excellent job minimizing the number of issues that could crop up in a Service Pack upgrade by doing a thorough job updating your driver sets and clearing out old junk before you roll out the update. Read on to see how he does it: Just wanted to pass on a suggestion for people worried about installing Service Packs.  I came up with a ‘method’ a couple years back that seems to work well. Run Windows / Microsoft Update to get all updates EXCEPT the Service Pack. Use Secunia PSI to find any other updates you need. Use CCleaner or the Windows disk cleanup tools to get rid of all the old garbage out there.  Make sure that you include old system updates. Obviously, back up anything you really care about.  An image backup can be real nice to have if things go wrong. Download the correct SP version from Microsoft.com; do not use Windows / Microsoft Update to get it.  Make sure you have the 64 bit version if that’s what you have installed on your PC. Make sure that EVERYTHING that affects the OS is up to date.  That includes all sorts of drivers, starting with video and audio.  And if you have an Intel chipset, use the Intel Driver Utility to update those drivers.  It’s very quick and easy.  For the video and audio drivers, some can be updated by Intel, some by utilities on the vendor web sites, and some you just have to figure out yourself.  But don’t be lazy here; old drivers and Windows Service Packs are a poor mix. If you have 3rd party software, check to see if they have any updates for you.  They might not say that they are for the Service Pack but you cut your risk of things not working if you do this. Shut off the Antivirus software (especially if 3rd party). Reboot, hitting F8 to get the SafeMode menu.  Choose SafeMode with Networking. Log into the Administrator account to ensure that you have the right to install the SP. Run the SP.  It won’t be very fancy this way.  Maybe 45 minutes later it will reboot and then finish configuring itself, finally letting you log in. Total installation time on most of my PC’s was about 1 hour but that followed hours of preparation on each. On a separate note, I recently got on the Nvidia web site and their utility told me I had a new driver available for my GeForce 8600M GS.  This laptop had come with Vista, now has Win 7 SP1.  I had a big surprise from this driver update; the Windows Experience Score on the graphics side went way up.  Kudo’s to Nvidia for doing a driver update that actually helps day to day usage.  And unlike ATI’s updates (which I need for my AGP based system), this update was fairly quick and very easy.  Also, Nvidia drivers have never, as I can recall, given me BSOD’s, many of which I’ve gotten from ATI (TDR errors).How to Enable Google Chrome’s Secret Gold IconHTG Explains: What’s the Difference Between the Windows 7 HomeGroups and XP-style Networking?Internet Explorer 9 Released: Here’s What You Need To Know
