• Computer crashes on resume from standby almost every time

  - by Los Frijoles

  I am running Ubuntu 12.04 on a Core i5 2500K and ASRock Z68 Pro3-M motherboard (no graphics card, hd is a WD Green 1TB, and cd drive is some cheap lite-on drive). Since installing 12.04, my computer has been freezing after resume, but not every time. When I start to resume, it starts going normally with a blinking cursor on the screen and then sometimes it will continue on to the gnome 3 unlock screen. Most of the time, however, it will blink for a little bit and then the monitor will flip modes and shut off due to no signal. Pressing keys on the keyboard gets no response (num lock light doesn't respond, Ctrl-Alt-F1 fails to drop it into a terminal, Ctrl-Alt-Backspace doesn't work) and so I assume the computer is crashed. The worst part is, the logs look entirely normal. Here is my system log during one of these crashes and my subsequent hard poweroff and restart: Jun 6 21:54:43 kcuzner-desktop udevd[10448]: inotify_add_watch(6, /dev/dm-2, 10) failed: No such file or directory Jun 6 21:54:43 kcuzner-desktop udevd[10448]: inotify_add_watch(6, /dev/dm-2, 10) failed: No such file or directory Jun 6 21:54:43 kcuzner-desktop udevd[10448]: inotify_add_watch(6, /dev/dm-1, 10) failed: No such file or directory Jun 6 21:54:43 kcuzner-desktop udevd[12419]: inotify_add_watch(6, /dev/dm-0, 10) failed: No such file or directory Jun 6 21:54:43 kcuzner-desktop udevd[10448]: inotify_add_watch(6, /dev/dm-0, 10) failed: No such file or directory Jun 6 22:09:01 kcuzner-desktop CRON[9061]: (root) CMD ( [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {} 2>/dev/null \; -delete) Jun 6 22:17:01 kcuzner-desktop CRON[22142]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Jun 6 22:39:01 kcuzner-desktop CRON[26909]: (root) CMD ( [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {} 2>/dev/null \; -delete) Jun 6 22:54:21 kcuzner-desktop kernel: [57905.560822] show_signal_msg: 36 callbacks suppressed Jun 6 22:54:21 kcuzner-desktop kernel: [57905.560828] chromium-browse[9139]: segfault at 0 ip 00007f3a78efade0 sp 00007fff7e2d2c18 error 4 in chromium-browser[7f3a76604000+412b000] Jun 6 23:05:43 kcuzner-desktop kernel: [58586.415158] chromium-browse[21025]: segfault at 0 ip 00007f3a78efade0 sp 00007fff7e2d2c18 error 4 in chromium-browser[7f3a76604000+412b000] Jun 6 23:09:01 kcuzner-desktop CRON[13542]: (root) CMD ( [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -mindepth 1 -maxdepth 1 -type f -cmin +$(/usr/lib/php5/maxlifetime) ! -execdir fuser -s {} 2>/dev/null \; -delete) Jun 6 23:12:43 kcuzner-desktop kernel: [59006.317590] usb 2-1.7: USB disconnect, device number 8 Jun 6 23:12:43 kcuzner-desktop kernel: [59006.319672] sd 7:0:0:0: [sdg] Synchronizing SCSI cache Jun 6 23:12:43 kcuzner-desktop kernel: [59006.319737] sd 7:0:0:0: [sdg] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK Jun 6 23:17:01 kcuzner-desktop CRON[26580]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Jun 6 23:19:04 kcuzner-desktop acpid: client connected from 29925[0:0] Jun 6 23:19:04 kcuzner-desktop acpid: 1 client rule loaded Jun 6 23:19:07 kcuzner-desktop rtkit-daemon[1835]: Successfully made thread 30131 of process 30131 (n/a) owned by '104' high priority at nice level -11.

• Add a Sleep Timer to Windows 7 Media Center

  - by DigitalGeekery

  Do you make it a habit of falling asleep at night while watching Windows Media Center? Today we are going to take a look at the MC7 Sleep Timer for Windows 7 Media Center. This simple little plugin allows you to schedule an automatic shutdown time in Media Center. Note: At this point MC7 Sleep Timer doesn’t work with extenders. If you’re using ClamAV or Panda it may detect this plugin as a virus, we’ve tested it and this is a false positive for these two antivirus apps. Installation and Usage Download and install MC7 Sleep Timer. (See download below) After the installation is finished, you will find MC7 Sleep Timer located in the Media Center Extras Library. Click on the tile to open the timer and configure your settings. The MC7 Sleep Timer will open in full screen mode. You can choose to shutdown the PC after 30 or 60 minutes, create a custom length shutdown timer at any 5 minute interval, or select the exact time you want the PC to shutdown.  After setting your PC to shutdown, you’ll get an audio confirmation. To set a custom timer length, scroll to the “Custom timer” option and click right or left on your Media Center remote or, the right or left arrow keys, to choose how many minutes before shutdown. To schedule a shutdown for a certain time, browse to the “Shutdown at time” button, and scroll right or left with the arrow keys on the keyboard or remote. When you’ve chosen your time, hit “Enter” on the keyboard or “OK” on the remote.   Clicking the “Monitor Off” button will turn off only the monitor and “Cancel Timer” will cancel your shutdown request. Conclusion If you often find yourself falling asleep every night watching Media Center and then fumbling and stumbling in the middle of the night to shutdown your computer, MC7 Sleep timer might just be a perfect addition to your Media Center setup.

• DevConnections jQuery Session Slides and Samples posted

  - by Rick Strahl

  I’ve posted all of my slides and samples from the DevConnections VS 2010 Launch event last week in Vegas. All three sessions are contained in a single zip file which contains all slide decks and samples in one place: www.west-wind.com/files/conferences/jquery.zip There were 3 separate sessions: Using jQuery with ASP.NET Starting with an overview of jQuery client features via many short and fun examples, you'll find out about core features like the power of selectors to select document elements, manipulate these elements with jQuery's wrapped set methods in a browser independent way, how to hook up and handle events easily and generally apply concepts of unobtrusive JavaScript principles to client scripting. The session also covers AJAX interaction between jQuery and the .NET server side code using several different approaches including sending HTML and JSON data and how to avoid user interface duplication by using client side templating. This session relies heavily on live examples and walk-throughs. jQuery Extensibility and Integration with ASP.NET Server Controls One of the great strengths of the jQuery Javascript framework is its simple, yet powerful extensibility model that has resulted in an explosion of plug-ins available for jQuery. You need it - chances are there's a plug-in for it! In this session we'll look at a few plug-ins to demonstrate the power of the jQuery plug-in model before diving in and creating our own custom jQuery plug-ins. We'll look at how to create a plug-in from scratch as well as discussing when it makes sense to do so. Once you have a plug-in it can also be useful to integrate it more seamlessly with ASP.NET by creating server controls that coordinate both server side and jQuery client side behavior. I'll demonstrate a host of custom components that utilize a combination of client side jQuery functionality and server side ASP.NET server controls that provide smooth integration in the user interface development process. This topic focuses on component development both for pure client side plug-ins and mixed mode controls. jQuery Tips and Tricks This session was kind of a last minute substitution for an ASP.NET AJAX talk. Nothing too radical here :-), but I focused on things that have been most productive for myself. Look at the slide deck for individual points and some of the specific samples.   It was interesting to see that unlike in previous conferences this time around all the session were fairly packed – interest in jQuery is definitely getting more pronounced especially with microsoft’s recent announcement of focusing on jQuery integration rather than continuing on the path of ASP.NET AJAX – which is a welcome change. Most of the samples also use the West Wind Web & Ajax Toolkit and the support tools contained within it – a snapshot version of the toolkit is included in the samples download. Specicifically a number of the samples use functionality in the ww.jquery.js support file which contains a fairly large set of plug-ins and helper functionality – most of these pieces while contained in the single file are self-contained and can be lifted out of this file (several people asked). Hopefully you'll find something useful in these slides and samples.© Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET  jQuery

• An XEvent a Day (20 of 31) – Mapping Extended Events to SQL Trace

  - by Jonathan Kehayias

  One of the biggest problems that I had with getting into Extended Events was mapping the Events available in Extended Events to the Events that I knew from SQL Trace. With so many Events to choose from in Extended Events, and a different organization of the Events, it is really easy to get lost when trying to find things. Add to this the fact that Event names don’t match up to Trace Event names in SQL Server 2008 and 2008 R2, and not all of the Events from Trace are implemented in SQL Server 2008...(read more)

• Pro ASP.NET MVC Framework Review

  - by Ben Griswold

  Early in my career, when I wanted to learn a new technology, I’d sit in the bookstore aisle and I’d work my way through each of the available books on the given subject.  Put in enough time in a bookstore and you can learn just about anything. I used to really enjoy my time in the bookstore – but times have certainly changed.  Whereas books used to be the only place I could find solutions to my problems, now they may be the very last place I look.  I have been working with the ASP.NET MVC Framework for more than a year.  I have a few projects and a couple of major deployments under my belt and I was able to get up to speed with the framework without reading a single book*.  With so many resources at our fingertips (podcasts, screencasts, blogs, stackoverflow, open source projects, www.asp.net, you name it) why bother with a book? Well, I flipped through Steven Sanderson’s Pro ASP.NET MVC Framework a few months ago. And since it is prominently displayed in my co-worker’s office, I tend to pick it up as a reference from time to time.  Last week, I’m not sure why, I decided to read it cover to cover.  Man, did I eat this book up.  Granted, a lot of what I read was review, but it was only review because I had already learned lessons by piecing the puzzle together for myself via various sources. If I were starting with ASP.NET MVC (or ASP.NET Web Deployment in general) today, the first thing I would do is buy Steven Sanderson’s Pro ASP.NET MVC Framework and read it cover to cover. Steven Sanderson did such a great job with this book! As much as I appreciated the in-depth model, view, and controller talk, I was completely impressed with all the extra bits which were included.  There a was nice overview of BDD, view engine comparisons, a chapter dedicated to security and vulnerabilities, IoC, TDD and Mocking (of course), IIS deployment options and a nice overview of what the .NET platform and C# offers.  Heck, Sanderson even include bits about webforms! The book is fantastic and I highly recommend it – even if you think you’ve already got your head around ASP.NET MVC.  By the way, procrastinators may be in luck.  ASP.NET MVC V2 Framework can be pre-ordered.  You might want to jump right into the second edition and find out what Sanderson has to say about MVC 2. * Actually, I did read through the free bits of Professional ASP.NET MVC 1.0.  But it was just a chapter – albeit a really long chapter.

• Minimal set of critical database operations

  - by Juan Carlos Coto

  In designing the data layer code for an application, I'm trying to determine if there is a minimal set of database operations (both single and combined) that are essential for proper application function (i.e. the database is left in an expected state after every data access call). Is there a way to determine the minimal set of database operations (functions, transactions, etc.) that are critical for an application to function correctly? How do I find it? Thanks very much!

• CDN on Hosted Service in Windows Azure

  - by Shaun

  Yesterday I told Wang Tao, an annoying colleague sitting beside me, about how to make the static content enable the CDN in his website which had just been published on Windows Azure. The approach would be Move the static content, the images, CSS files, etc. into the blob storage. Enable the CDN on his storage account. Change the URL of those static files to the CDN URL. I think these are the very common steps when using CDN. But this morning I found that the new Windows Azure SDK 1.4 and new Windows Azure Developer Portal had just been published announced at the Windows Azure Blog. One of the new features in this release is about the CDN, which means we can enabled the CDN not only for a storage account, but a hosted service as well. Within this new feature the steps I mentioned above would be turned simpler a lot.   Enable CDN for Hosted Service To enable the CDN for a hosted service we just need to log on the Windows Azure Developer Portal. Under the “Hosted Services, Storage Accounts & CDN” item we will find a new menu on the left hand side said “CDN”, where we can manage the CDN for storage account and hosted service. As we can see the hosted services and storage accounts are all listed in my subscriptions. To enable a CDN for a hosted service is veru simple, just select a hosted service and click the New Endpoint button on top. In this dialog we can select the subscription and the storage account, or the hosted service we want the CDN to be enabled. If we selected the hosted service, like I did in the image above, the “Source URL for the CDN endpoint” will be shown automatically. This means the windows azure platform will make all contents under the “/cdn” folder as CDN enabled. But we cannot change the value at the moment. The following 3 checkboxes next to the URL are: Enable CDN: Enable or disable the CDN. HTTPS: If we need to use HTTPS connections check it. Query String: If we are caching content from a hosted service and we are using query strings to specify the content to be retrieved, check it. Just click the “Create” button to let the windows azure create the CDN for our hosted service. The CDN would be available within 60 minutes as Microsoft mentioned. My experience is that about 15 minutes the CDN could be used and we can find the CDN URL in the portal as well.   Put the Content in CDN in Hosted Service Let’s create a simple windows azure project in Visual Studio with a MVC 2 Web Role. When we created the CDN mentioned above the source URL of CDN endpoint would be under the “/cdn” folder. So in the Visual Studio we create a folder under the website named “cdn” and put some static files there. Then all these files would be cached by CDN if we use the CDN endpoint. The CDN of the hosted service can cache some kind of “dynamic” result with the Query String feature enabled. We create a controller named CdnController and a GetNumber action in it. The routed URL of this controller would be /Cdn/GetNumber which can be CDN-ed as well since the URL said it’s under the “/cdn” folder. In the GetNumber action we just put a number value which specified by parameter into the view model, then the URL could be like /Cdn/GetNumber?number=2. 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Mvc; 6:  7: namespace MvcWebRole1.Controllers 8: { 9: public class CdnController : Controller 10: { 11: // 12: // GET: /Cdn/ 13:  14: public ActionResult GetNumber(int number) 15: { 16: return View(number); 17: } 18:  19: } 20: } And we add a view to display the number which is super simple. 1: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<int>" %> 2:  3: <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> 4: GetNumber 5: </asp:Content> 6:  7: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 8:  9: <h2>The number is: <% 1: : Model.ToString() %></h2> 10:  11: </asp:Content> Since this action is under the CdnController the URL would be under the “/cdn” folder which means it can be CDN-ed. And since we checked the “Query String” the content of this dynamic page will be cached by its query string. So if I use the CDN URL, http://az25311.vo.msecnd.net/GetNumber?number=2, the CDN will firstly check if there’s any content cached with the key “GetNumber?number=2”. If yes then the CDN will return the content directly; otherwise it will connect to the hosted service, http://aurora-sys.cloudapp.net/Cdn/GetNumber?number=2, and then send the result back to the browser and cached in CDN. But to be notice that the query string are treated as string when used by the key of CDN element. This means the URLs below would be cached in 2 elements in CDN: http://az25311.vo.msecnd.net/GetNumber?number=2&page=1 http://az25311.vo.msecnd.net/GetNumber?page=1&number=2 The final step is to upload the project onto azure. Test the Hosted Service CDN After published the project on azure, we can use the CDN in the website. The CDN endpoint we had created is az25311.vo.msecnd.net so all files under the “/cdn” folder can be requested with it. Let’s have a try on the sample.htm and c_great_wall.jpg static files. Also we can request the dynamic page GetNumber with the query string with the CDN endpoint. And if we refresh this page it will be shown very quickly since the content comes from the CDN without MCV server side process. We style of this page was missing. This is because the CSS file was not includes in the “/cdn” folder so the page cannot retrieve the CSS file from the CDN URL.   Summary In this post I introduced the new feature in Windows Azure CDN with the release of Windows Azure SDK 1.4 and new Developer Portal. With the CDN of the Hosted Service we can just put the static resources under a “/cdn” folder so that the CDN can cache them automatically and no need to put then into the blob storage. Also it support caching the dynamic content with the Query String feature. So that we can cache some parts of the web page by using the UserController and CDN. For example we can cache the log on user control in the master page so that the log on part will be loaded super-fast. There are some other new features within this release you can find here. And for more detailed information about the Windows Azure CDN please have a look here as well.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• SQLAuthority News – Social Media Series – YouTube and Movies

  - by pinaldave

  Pinal Dave on Youtube! Some people might not know it, but YouTube is actually more than a place to watch funny cat videos and people singing their favorite pop songs – it’s actually a social media site.  When you are a member of YouTube you can follow people who regularly post videos, post video responses of your own, and even gain a following for your own videos.  I myself was not aware of YouTube’s potential until recently, when I started to make SQL Server in Sixty Seconds videos. YouTube is very different than other types of social media, and a big factor is that anyone can look at videos without being a member.  Unlike other social media sites, like Twitter and Facebook, you have to have an account in order to participate.  But on YouTube you are even more anonymous.  To make and post videos you need an account, but anyone who comes to the site can look at what you’ve made without signing in or leaving any trace of having seen your material.  This makes YouTube very anonymous and hard to track. However, we should not overlook the power of video on the internet.  Over the past few months I have been making SQL Server in Sixty Second videos and have come to love it.  It is very exciting to be able to talk about a subject that mostly I write about, and for many people video is far more accessible and easy to understand.   I have really enjoyed diving into something new, and would love to have more people check out these videos and give me feedback.  You can find me at www.youtube.com/user/pinaldave. I am very excited with all the possibilities on YouTube and it might just be the technology evangelist in me, but I would love for other people to discover how fun and exciting this site can be, too.  Don’t think of it as just a place to find funny videos and waste a few minutes of your time, think of it as a place to learn and interact with interesting people.  Come watch a few of my videos, while you’re there.  Remember, everything is free and there are no contracts to sign, but I hope that you get as excited as I am and join up.  We need more people creating good content on this site!

• SQL SERVER – Weekly Series – Memory Lane – #051

  - by Pinal Dave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Explanation and Understanding NOT NULL Constraint NOT NULL is integrity CONSTRAINT. It does not allow creating of the row where column contains NULL value. Most discussed questions about NULL is what is NULL? I will not go in depth analysis it. Simply put NULL is unknown or missing data. When NULL is present in database columns, it can affect the integrity of the database. I really do not prefer NULL in the database unless they are absolutely necessary. Three T-SQL Script to Create Primary Keys on Table I have always enjoyed writing about three topics Constraint and Keys, Backup and Restore and Datetime Functions. Primary Keys constraints prevent duplicate values for columns and provides a unique identifier to each column, as well it creates clustered index on the columns. 2008 Get Numeric Value From Alpha Numeric String – UDF for Get Numeric Numbers Only SQL is great with String operations. Many times, I use T-SQL to do my string operation. Let us see User Defined Function, which I wrote a few days ago, which will return only Numeric values from Alpha Numeric values. Introduction and Example of UNION and UNION ALL It is very much interesting when I get requests from blog reader to re-write my previous articles. I have received few requests to rewrite my article SQL SERVER – Union vs. Union All – Which is better for performance? with examples. I request you to read my previous article first to understand what is the concept and read this article to understand the same concept with an example. Downgrade Database for Previous Version The main questions is how they can downgrade the from SQL Server 2005 to SQL Server 2000? The answer is : Not Possible. Get Common Records From Two Tables Without Using Join Following is my scenario, Suppose Table 1 and Table 2 has same column e.g. Column1 Following is the query, 1. Select column1,column2 From Table1 2. Select column1 From Table2 I want to find common records from these tables, but I don’t want to use the Join clause because for that I need to specify the column name for Join condition. Will you help me to get common records without using Join condition? I am using SQL Server 2005. Retrieve – Select Only Date Part From DateTime – Best Practice – Part 2 A year ago I wrote a post about SQL SERVER – Retrieve – Select Only Date Part From DateTime – Best Practice where I have discussed two different methods of getting the date part from datetime. Introduction to CLR – Simple Example of CLR Stored Procedure CLR is an abbreviation of Common Language Runtime. In SQL Server 2005 and later version of it database objects can be created which are created in CLR. Stored Procedures, Functions, Triggers can be coded in CLR. CLR is faster than T-SQL in many cases. CLR is mainly used to accomplish tasks which are not possible by T-SQL or can use lots of resources. The CLR can be usually implemented where there is an intense string operation, thread management or iteration methods which can be complicated for T-SQL. Implementing CLR provides more security to the Extended Stored Procedure. 2009 Comic Slow Query – SQL Joke Before Presentation After Presentation Enable Automatic Statistic Update on Database In one of the recent projects, I found out that despite putting good indexes and optimizing the query, I could not achieve an optimized performance and I still received an unoptimized response from the SQL Server. On examination, I figured out that the culprit was statistics. The database that I was trying to optimize had auto update of the statistics was disabled. Recently Executed T-SQL Query Please refer to blog post  query to recently executed T-SQL query on database. Change Collation of Database Column – T-SQL Script – Consolidating Collations – Extention Script At some time in your DBA career, you may find yourself in a position when you sit back and realize that your database collations have somehow run amuck, or are faced with the ever annoying CANNOT RESOLVE COLLATION message when trying to join data of varying collation settings. 2010 Visiting Alma Mater – Delivering Session on Database Performance and Career – Nirma Institute of Technology Everyone always dreams of visiting their school and college, where they have studied once. It is a great feeling to see the college once again – where you have spent the wonderful golden years of your time. College time is filled with studies, education, emotions and several plans to build a future. I consider myself fortunate as I got the opportunity to study at some of the best places in the world. Change Column DataTypes There are times when I feel like writing that I am a day older in SQL Server. In fact, there are many who are looking for a solution that is simple enough. Have you ever searched online for something very simple. I often do and enjoy doing things which are straight forward and easy to change. 2011 Three DMVs – sys.dm_server_memory_dumps – sys.dm_server_services – sys.dm_server_registry In this blog post we will see three new DMVs which are introduced in Denali. The DMVs are very simple and there is not much to describe them. So here is the simple game. I will be asking a question back to you after seeing the result of the each of the DMV and you help me to complete this blog post. A Simple Quiz – T-SQL Brain Trick If you have some time, I strongly suggest you try this quiz out as it is for sure twists your brain. 2012 List All The Column With Specific Data Types in Database 5 years ago I wrote script SQL SERVER – 2005 – List All The Column With Specific Data Types, when I read it again, it is very much relevant and I liked it. This is one of the script which every developer would like to keep it handy. I have upgraded the script bit more. I have included few additional information which I believe I should have added from the beginning. It is difficult to visualize the final script when we are writing it first time. Find First Non-Numeric Character from String The function PATINDEX exists for quite a long time in SQL Server but I hardly see it being used. Well, at least I use it and I am comfortable using it. Here is a simple script which I use when I have to identify first non-numeric character. Finding Different ColumnName From Almost Identitical Tables Well here is the interesting example of how we can use sys.column catalogue views and get the details of the newly added column. I have previously written about EXCEPT over here which is very similar to MINUS of Oracle. Storing Data and Files in Cloud – Dropbox – Personal Technology Tip I thought long and hard about doing a Personal Technology Tips series for this blog.  I have so many tips I’d like to share.  I am on my computer almost all day, every day, so I have a treasure trove of interesting tidbits I like to share if given the chance.  The only thing holding me back – which tip to share first?  The first tip obviously has the weight of seeming like the most important.  But this would mean choosing amongst my favorite tricks and shortcuts.  This is a hard task.

• Getting Current with Visual Studio 2010 for Web Developers

  - by plitwin

  I don't know about you, but I find it kind of crazy at times figuring out if I have the latest of everything there is for the Visual Studio 2010 developer from Microsoft. (This does not include any third-party components, just recommended updates from Microsoft.) And the be honest, the msn.microsoft.com and asp.net sites are not that helpful in figuring this out.In an effort to help, I have enumerated here what the latest VS 2010 setup should include, complete with download links. When you install everything here, you will be able to develop ASP.NET 4.0 Web Forms and ASP.NET MVC 3 applications and web sites in addition to the other stuff your version of Visual Studio supports (e.g., Silverlight, WPF, etc.). These downloads will also include NuGet and the Entity Framework 4.1, so there is no need to download this software separately.Visual Studio 2010. First of all, you need to purchase and install Visual Studio 2010 itself. For the free Express version, you can download it from Visual Web Developer 2010 ExpressVisual Studio Service Pack 1 (released Spring 2011).This is a must-have download that fixes a bunch of bugs and a number of enhancements too including preliminary support for HTML5 and CSS3. See #4 below for better support of these web technologies. Download and install from VS 2010 SP1 download page. You can find details on the features of the service pack here. ASP.NET MVC3 Tools Update (released Spring 2011)If you are using ASP.NET MVC 3, then you should also download install this update for Visual Studio from ASP.NET MVC3 Tools Update download page. This update improves Visual Studio's support for MVC 3, including better scaffolding, NuGet, Entity Framework 4.1, and more. A good overview of the updates can be found in Phil Haack's blog post.Web Standards Update for Microsoft Visual Studio 2010 SP1 (released June 2011)This is an update to VS 2010 SP1 that "brings VS 2010 intellisense & validation as close to W3C specification as we could get via means of an extension". Download and install from Web Standards Update download page. A good description of the changes can be found in the Visual Web Developer Team blog post.Note: I don't control these download pages, so it is possible they will change. If so, I will do my best to update these links. This information was current as of June 24, 2011.

• Control Your Favorite Music Player from Firefox

  - by Asian Angel

  Do you love listening to music while you browse? Now you can access and control your favorite music player directly from Firefox with the FoxyTunes extension. FoxyTunes in Action Once you have installed the extension and restarted Firefox you will see the FoxyTunes Toolbar located in the “Status Bar”. The default media app is Windows Media Player but can be easily changed. Here are the buttons/items available with the default settings: Search, FoxyTunes Main Menu, Show Player, Select Player, Previous Track, Play, Next Track, Mute On/Off, Volume, Play File, Twitty Tunes, Foxy Tunes Search/Explore, Open FoxyTunes Planet, & Toggle Visibility/Drag and drop to move. Note: You can hide or show individual buttons/items using the “FoxyTunes Menus”. Curious about the media players that FoxyTunes works with? Here is a complete listing…that definitely looks terrific! Notice that the currently selected media app is “bold and blue”. For our example we chose Spotify which we have previously covered. Keep in mind that you may or may not need to have your favorite media app open prior to “starting” FoxyTunes up (i.e. Play Button). Here is a good look at the “FoxyTunes Main Menu” and “Controls Sub-Menu”. The “Extras Menu”…if you click on skins you will be taken to the FoxyTunes Skins webpage. Here is a closer look into the “Configurations Menu” and one of the sub-menus. You do not need to look for options in the “Add-ons Manager Window”…everything you need is contained in these menus. If you do not like having FoxyTunes in the “Status Bar” you can easily drag and drop it to another toolbar. You can also condense the appearance of FoxyTunes using the small “triangle buttons” that are located in different spots throughout the “FoxyTunes Toolbar”. With just a click or two you can greatly reduce its’ impact on your UI. Conclusion If you love listening to music while browsing then the FoxyTunes extension will let you take care of everything right from your browser. Links Download the FoxyTunes extension (Mozilla Add-ons) Download the FoxyTunes extension (Extension Homepage) *Note: FoxyTunes add-ins for Internet Explorer and Yahoo! Messenger available here.

• Command line mode only -- successful login only brings me back to login screen

  - by seth

  whenever I log in the screen goes black, I see a glimpse of terminal-esque text, and then it brings me back to the log in screen (Ubuntu 12.04). I can enter and log in via the command line. The guest account works find. I think this happened because I edited some Xorg related file trying to make an external monitor work with my laptop. I copy pasted from a forum post so I dont recall the file or what i put in the file. Can't find the forum post again and my bash history wasn't recorded from that session. I tried reinstalling Xorg and ubuntu-desktop, nvidia, resetting any configs I could find... I'm really at a loss of what to do.

• Video on Architecture and Code Quality using Visual Studio 2012&ndash;interview with Marcel de Vries and Terje Sandstrom by Adam Cogan

  - by terje

  Find the video HERE. Adam Cogan did a great Web TV interview with Marcel de Vries and myself on the topics of architecture and code quality.  It was real fun participating in this session.  Although we know each other from the MVP ALM community,  Marcel, Adam and I haven’t worked together before. It was very interesting to see how we agreed on so many terms, and how alike we where thinking.  The basics of ensuring you have a good architecture and how you could document it is one thing.  Also, the same agreement on the importance of having a high quality code base, and how we used the Visual Studio 2012 tools, and some others (NDepend for example)  to measure and ensure that the code quality was where it should be.  As the tools, methods and thinking popped up during the interview it was a lot of “Hey !  I do that too!”.  The tools are not only for “after the fact” work, but we use them during the coding.  That way the tools becomes an integrated part of our coding work, and helps us to find issues we may have overlooked.  The video has a bunch of call outs, pinpointing important things to remember. These are also listed on the corresponding web page. I haven’t seen that touch before, but really liked this way of doing it – it makes it much easier to spot the highlights.  Titus Maclaren and Raj Dhatt from SSW have done a terrific job producing this video.  And thanks to Lei Xu for doing the camera and recording job.  Thanks guys ! Also, if you are at TechEd Amsterdam 2012, go and listen to Adam Cogan in his session on “A modern architecture review: Using the new code review tools” Friday 29th, 10.15-11.30 and Marcel de Vries session on “Intellitrace, what is it and how can I use it to my benefit” Wednesday 27th, 5-6.15 The highlights points out some important practices.  I’ll elaborate on a few of them here: Add instructions on how to compile the solution.  You do this by adding a text file with instructions to the solution, and keep it under source control.  These instructions should contain what is needed on top of a standard install of Visual Studio.  I do a lot of code reviews, and more often that not, I am not even able to compile the program, because they have used some tool or library that needs to be installed.  The same applies to any new developer who enters into the team, so do this to increase your productivity when the team changes, or a team member switches computer. Don’t forget to document what you have to configure on the computer, the IIS being a common one. The more automatic you can do this, the better.  Use NuGet to get down libraries. When the text document gets more than say, half a page, with a bunch of different things to do, convert it into a powershell script instead.  The metrics warning levels.  These are very conservatively set by Microsoft.  You rarely see anything but green, and besides, you should have color scales for each of the metrics.  I have a blog post describing a more appropriate set of levels, based on both research work and industry “best practices”.  The essential limits are: Cyclomatic complexity and coupling:  Higher numbers are worse On method levels: Green :  From 0 to 10 Yellow:  From 10 to 20  (some say 15).   Acceptable, but have a look to see if there is something unneeded here. Red: From 20 to 40:   Action required, get these down. Bleeding Red: Above 40   This is the real red alert.  Immediate action!  (My invention, as people have asked what do I do when I have cyclomatic complexity of 150.  The only answer I could think of was: RUN! ) Maintainability index:  Lower numbers are worse, scale from 0 to 100. On method levels: Green:  60 to 100 Yellow:  40 – 60.    You will always have methods here too, accept the higher ones, take a look at those who are down to the lower limit.  Check up against the other metrics.) Red:  20 – 40:  Action required, fix these. Bleeding red:  Below 20.  Immediate action required. When doing metrics analysis, you should leave the generated code out.  You do this by adding attributes, unfortunately Microsoft has “forgotten” to add these to all their stuff, so you might have to add them to some of the code.  It most cases it can be done so that it is not overwritten by a new round of code generation.  Take a look a my blog post here for details on how to do that. Class level metrics might also be useful, at least for coupling and maintenance.  But it is much more difficult to set any fixed limits on those.  Any metric aggregations on higher level tend to be pretty useless, as the number of methods vary pretty much, and there are little science on what number of methods can be regarded as good or bad.  NDepend have a recommendation, but they say it may vary too.  And in these days of data binding, the number might be pretty high, as properties counts as methods.  However, if you take the worst case situations, classes with more than 20 methods are suspicious, and coupling and cyclomatic complexity go red above 20, so any classes with more than 20x20 = 400 for these measures should be checked over. In the video we mention the SOLID principles, coined by “Uncle Bob” (Richard Martin). One of them, the Dependency Inversion principle we discuss in the video.  It is important to note that this principle is NOT on whether you should use a Dependency Inversion Container or not, it is about how you design the interfaces and interactions between your classes.  The Dependency Inversion Container is just one technique which is based on this principle, but which main purpose is to isolate things you would like to change at runtime, for example if you implement a plug in architecture.  Overuse of a Dependency Inversion Container is however, NOT a good thing.  It should be used for a purpose and not as a general DI solution.  The general DI solution and thinking however is useful far beyond the DIC.   You should always “program to an abstraction”, and not to the concreteness.  We also talk a bit about the GRASP patterns, a term coined by Craig Larman in his book Applying UML and design patterns. GRASP patterns stand for General Responsibility Assignment Software Patterns and describe fundamental principles of object design and responsibility assignment.  What I find great with these patterns is that they is another way to focus on the responsibility of a class.  One of the things I most often found that is broken in software designs, is that the class lack responsibility, and as a result there are a lot of classes mucking around in the internals of the other classes.  We also discuss the term “Code Smells”.  This term was invented by Kent Beck and Martin Fowler when they worked with Fowler’s “Refactoring” book. A code smell is a set of “bad” coding practices, which are the drivers behind a corresponding set of refactorings.  Here is a good list of the smells, and their corresponding refactor patterns.

• Easier ASP.NET MVC Routing

  - by Steve Wilkes

  I've recently refactored the way Routes are declared in an ASP.NET MVC application I'm working on, and I wanted to share part of the system I came up with; a really easy way to declare and keep track of ASP.NET MVC Routes, which then allows you to find the name of the Route which has been selected for the current request. Traditional MVC Route Declaration Traditionally, ASP.NET MVC Routes are added to the application's RouteCollection using overloads of the RouteCollection.MapRoute() method; for example, this is the standard way the default Route which matches /controller/action URLs is created: routes.MapRoute(     "Default",     "{controller}/{action}/{id}",     new { controller = "Home", action = "Index", id = UrlParameter.Optional }); The first argument declares that this Route is to be named 'Default', the second specifies the Route's URL pattern, and the third contains the URL pattern segments' default values. To then write a link to a URL which matches the default Route in a View, you can use the HtmlHelper.RouteLink() method, like this: @ this.Html.RouteLink("Default", new { controller = "Orders", action = "Index" }) ...that substitutes 'Orders' into the {controller} segment of the default Route's URL pattern, and 'Index' into the {action} segment. The {Id} segment was declared optional and isn't specified here. That's about the most basic thing you can do with MVC routing, and I already have reservations: I've duplicated the magic string "Default" between the Route declaration and the use of RouteLink(). This isn't likely to cause a problem for the default Route, but once you get to dozens of Routes the duplication is a pain. There's no easy way to get from the RouteLink() method call to the declaration of the Route itself, so getting the names of the Route's URL parameters correct requires some effort. The call to MapRoute() is quite verbose; with dozens of Routes this gets pretty ugly. If at some point during a request I want to find out the name of the Route has been matched.... and I can't. To get around these issues, I wanted to achieve the following: Make declaring a Route very easy, using as little code as possible. Introduce a direct link between where a Route is declared, where the Route is defined and where the Route's name is used, so I can use Visual Studio's Go To Definition to get from a call to RouteLink() to the declaration of the Route I'm using, making it easier to make sure I use the correct URL parameters. Create a way to access the currently-selected Route's name during the execution of a request. My first step was to come up with a quick and easy syntax for declaring Routes. 1 . An Easy Route Declaration Syntax I figured the easiest way of declaring a route was to put all the information in a single string with a special syntax. For example, the default MVC route would be declared like this: "{controller:Home}/{action:Index}/{Id}*" This contains the same information as the regular way of defining a Route, but is far more compact: The default values for each URL segment are specified in a colon-separated section after the segment name The {Id} segment is declared as optional simply by placing a * after it That's the default route - a pretty simple example - so how about this? routes.MapRoute(     "CustomerOrderList",     "Orders/{customerRef}/{pageNo}",     new { controller = "Orders", action = "List", pageNo = UrlParameter.Optional },     new { customerRef = "^[a-zA-Z0-9]+$", pageNo = "^[0-9]+$" }); This maps to the List action on the Orders controller URLs which: Start with the string Orders/ Then have a {customerRef} set of characters and numbers Then optionally a numeric {pageNo}. And again, it’s quite verbose. Here's my alternative: "Orders/{customerRef:^[a-zA-Z0-9]+$}/{pageNo:^[0-9]+$}*->Orders/List" Quite a bit more brief, and again, containing the same information as the regular way of declaring Routes: Regular expression constraints are declared after the colon separator, the same as default values The target controller and action are specified after the -> The {pageNo} is defined as optional by placing a * after it With an appropriate parser that gave me a nice, compact and clear way to declare routes. Next I wanted to have a single place where Routes were declared and accessed. 2. A Central Place to Declare and Access Routes I wanted all my Routes declared in one, dedicated place, which I would also use for Route names when calling RouteLink(). With this in mind I made a single class named Routes with a series of public, constant fields, each one relating to a particular Route. With this done, I figured a good place to actually declare each Route was in an attribute on the field defining the Route’s name; the attribute would parse the Route definition string and make the resulting Route object available as a property. I then made the Routes class examine its own fields during its static setup, and cache all the attribute-created Route objects in an internal Dictionary. Finally I made Routes use that cache to register the Routes when requested, and to access them later when required. So the Routes class declares its named Routes like this: public static class Routes{     [RouteDefinition("Orders/{customerName}->Orders/Index")]     public const string OrdersCustomerIndex = "OrdersCustomerIndex";     [RouteDefinition("Orders/{customerName}/{orderId:^([0-9]+)$}->Orders/Details")]     public const string OrdersDetails = "OrdersDetails";     [RouteDefinition("{controller:Home}*/{action:Index}*")]     public const string Default = "Default"; } ...which are then used like this: @ this.Html.RouteLink(Routes.Default, new { controller = "Orders", action = "Index" }) Now that using Go To Definition on the Routes.Default constant takes me to where the Route is actually defined, it's nice and easy to quickly check on the parameter names when using RouteLink(). Finally, I wanted to be able to access the name of the current Route during a request. 3. Recovering the Route Name The RouteDefinitionAttribute creates a NamedRoute class; a simple derivative of Route, but with a Name property. When the Routes class examines its fields and caches all the defined Routes, it has access to the name of the Route through the name of the field against which it is defined. It was therefore a pretty easy matter to have Routes give NamedRoute its name when it creates its cache of Routes. This means that the Route which is found in RequestContext.RouteData.Route is now a NamedRoute, and I can recover the Route's name during a request. For visibility, I made NamedRoute.ToString() return the Route name and URL pattern, like this: The screenshot is from an example project I’ve made on bitbucket; it contains all the named route classes and an MVC 3 application which demonstrates their use. I’ve found this way of defining and using Routes much tidier than the default MVC system, and you find it useful too
