  • Through the Virtual Microscope–SQL Server and Hyper-V

    - by GavinPayneUK
    In my recent SQLBits conference session, Through the Virtual Looking Glass available to watch here , I spoke about monitoring SQL Server in a virtualised environment.  We looked at good and bad contention, where resource pressures which can adversely affect SQL Server might come from and most importantly how we can monitor the environment to detect them. Since then, I’ve been in discussions with some of the Microsoft product team who are focussed on optimising Windows 8 Hyper-V and SQL Server...(read more)

    - by Mala Narasimharajan
     It’s always good to hear feedback from practitioners – the ones who are in the trenches who have experienced both the good and the bad sides of enterprise software.   Gartner recently released a report which surveyed 260 data quality professionals from around the world and found that most expressed considerable satisfaction as a whole from their data quality tool vendors.  However, a couple of key findings stand out which include, Datanomic (acquired by Oracle), leading the pack in terms of overall customer satisfaction among data quality tools.  Read all about it right here http://bit.ly/Ay45SG

  • Using URL Rewrite with QDIG

    - by The Official Microsoft IIS Site
    One of the applications that I like to use on my websites it the Quick Digital Image Gallery (QDIG) , which is a simple PHP-based image gallery that has just enough features to be really useful without a lot of work on my part to get it working. (Simple is always better - ;-] .) Here's a screenshot of QDIG in action with some Bing photos: (Click to enlarge photo.) The trouble is, QDIG creates some really heinous query string lines; see the URL line in the following screenshot for an example:...(read more)

This is useful to do when we write if{} else {} statement and this is not helpful on that case. 7.

  • Nvidia Proprietary Drivers

    - by Ben
    I have an X79 motherboard and a GTX 670. I have tried to install every combination of Ubuntu 11.10, 12.04, 12.10, Linux Mint 13 and the Nvidia Driver 304.43, 295.xx, etc. I have read everything and pretty much tried everything...drivers from the site, PPAs, some random scripts, editing the xorg.conf file. It has been four days of futile effort. Should I just wait...or something? Has anyone gotten hardware like this to work?

  • Setting Up CDN...beginner questions

    - by RRN
    I am using MediaTemple web hosting and they are using Edgecast's CDN network. I am planning to join CDN service, so I read through the guide, but I am confused about the 'Update your code' section: Does the CDN apply to my website automatically (without editing HTML) after I updated the DNS zone file? How can I control which files going through the CDN or not? Also, I need to make sure it won't affect the Google Analytics results.

  • Identifying which pattern fits better.

    - by Daniel Grillo
    I'm developing a software to program a device. I have some commands like Reset, Read_Version, Read_memory, Write_memory, Erase_memory. Reset and Read_Version are fixed. They don't need parameters. Read_memory and Erase_memory need the same parameters that are Length and Address. Write_memory needs Lenght, Address and Data. For each command, I have the same steps in sequence, that are something like this sendCommand, waitForResponse, treatResponse. I'm having difficulty to identify which pattern should I use. Factory, Template Method, Strategy or other pattern. Edit I'll try to explain better taking in count the given comments and answers. I've already done this software and now I'm trying to refactoring it. I'm trying to use patterns, even if it is not necessary because I'm taking advantage of this little software to learn about some patterns. Despite I think that one (or more) pattern fits here and it could improve my code. When I want to read version of the software of my device, I don't have to assembly the command with parameters. It is fixed. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. To read a portion of the memory (maximum of 256 bytes), I have to assembly the command using the parameters Len and Address. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. To write a portion in the memory (maximum of 256 bytes), I have to assembly the command using the parameters Len, Address and Data. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. I think that I could use Template Method because I have almost the same algorithm for all. But the problem is some commands are fixes, others have 2 or 3 parameters. I think that parameters should be passed on the constructor of the class. But each class will have a constructor overriding the abstract class constructor. Is this a problem for the template method? Should I use other pattern?

  • BI Beginner: Why to Use Excel 2013 Now

    - by John Paul Cook
    Most corporations and many individuals are slow to adopt new versions of Microsoft Office, particularly if the upgrade to the previous version was very recent. Excel 2013 is a special case and offers significant productivity enhancements. If you do business intelligence work or otherwise make your living with Excel, adding (notice I didn’t say upgrading to) Excel 2013 now makes a lot of sense. The Power View feature in Excel 2013 is a completely sufficient reason to add Excel 2013. It has to be enabled,...(read more)

  • Google Chrome Loses ASP.NET Sessions - Need FavIcon

    - by nannette
    I had programmed a brilliant web page in ASP.NET 4.0 and lo and behold, this one page lost its sessions in Google Chrome. I could run it locally in debug and could not reproduce the issues in Chrome. Didn't happen in IE or Firefox, only Chrome on the published server. I finally found in a forum where someone mentioned that Google Chrome looks for favicons and if it doesn't find one it will throw a 302 redirect and kill the session. http://stackoverflow.com/questions/8247842/session-data-lost-in-chrome...(read more)

  • ClearTrace for SQL Server 2012

    - by Bill Graziano
    I’ve updated the beta for ClearTrace that support SQL Server 2012.  This requires SQL Server 2012 to be installed on the computer where ClearTrace is running.  It will read traces from SQL Server 2008 R2, SQL Server 2008 and SQL Server 2005. It includes some minor improvements in performance and handling large SQL statements. It should also give better errors. If you do find any of those errors, please report them in the support forum.

  • TechEd 2014 Day 3

    - by John Paul Cook
    There is some confusion about durability of data stored in SQL Server in-memory tables, so some review of the concepts is appropriate. The in-memory option is enabled at the database level. Enabling it at the database level only gives you the option to specify the in-memory feature on a table by table basis. No existing tables or new tables will by default become in-memory tables when you enable the feature at the database level. If you choose to make a table an in-memory table, by default it is...(read more)

  • Bringing Alerts and Operators together with Notifications

    - by fatherjack
    I have covered SQL Server Alerts (Alerts are good, arent they?) on this blog before and I more recently did a post regarding Notifications (Are your Jobs talking to you) and how they should be configured. Now we need to check that these things are linked up so that when an Alert condition is met that you get the appropriate Notifications sent to Operators. Straight into the code we need and then a review of what it does ... DECLARE @ChosenOperator SYSNAME DECLARE @FailSafeOp TABLE ...(read more)

  • Checking timeouts made more readable

    - by Markus
    I have several situations where I need to control timeouts in a technical application. Either in a loop or as a simple check. Of course – handling this is really easy, but none of these is looking cute. To clarify, here is some C# (Pseudo) code: private DateTime girlWentIntoBathroom; girlWentIntoBathroom = DateTime.Now; do { // do something } while (girlWentIntoBathroom.AddSeconds(10) > DateTime.Now); or if (girlWentIntoBathroom.AddSeconds(10) > DateTime.Now) MessageBox.Show("Wait a little longer"); else MessageBox.Show("Knock louder"); Now I was inspired by something a saw in Ruby on StackOverflow: Now I’m wondering if this construct can be made more readable using extension methods. My goal is something that can be read like “If girlWentIntoBathroom is more than 10 seconds ago” 1st attempt if (girlWentIntoBathroom > (10).Seconds().Ago()) MessageBox.Show("Wait a little longer"); else MessageBox.Show("Knock louder"); So I wrote an extension for integer that converts the integer into a TimeSpan public static TimeSpan Seconds(this int amount) { return new TimeSpan(0, 0, amount); } After that, I wrote an extension for TimeSpan like this: public static DateTime Ago(this TimeSpan diff) { return DateTime.Now.Add(-diff); } This works fine so far, but has a great disadvantage. The logic is inverted! Since girlWentIntoBathroom is a timestamp in the past, the right side of the equation needs to count backwards: impossible. Just inverting the equation is no solution, because it will invert the read sentence as well. 2nd attempt So I tried something new: if (girlWentIntoBathroom.IsMoreThan(10).SecondsAgo()) MessageBox.Show("Knock louder"); else MessageBox.Show("Wait a little longer"); IsMoreThan() needs to transport the past timestamp as well as the span for the extension SecondsAgo(). It could be: public static DateWithIntegerSpan IsMoreThan(this DateTime baseTime, int span) { return new DateWithIntegerSpan() { Date = baseTime, Span = span }; } Where DateWithIntegerSpan is simply: public class DateWithIntegerSpan { public DateTime Date {get; set;} public int Span { get; set; } } And SecondsAgo() is public static bool SecondsAgo(this DateWithIntegerSpan dateAndSpan) { return dateAndSpan.Date.Add(new TimeSpan(0, 0, dateAndSpan.Span)) < DateTime.Now; } Using this approach, the English sentence matches the expected behavior. But the disadvantage is, that I need a helping class (DateWithIntegerSpan). Has anyone an idea to make checking timeouts look more cute and closer to a readable sentence? Am I a little too insane thinking about something minor like this?
