  • SQL SERVER – Video – Performance Improvement in Columnstore Index

    - by pinaldave
    I earlier wrote an article about SQL SERVER – Fundamentals of Columnstore Index and it got very well accepted in community. However, one of the suggestion I keep on receiving for that article is that many of the reader wanted to see columnstore index in the action but they were not able to do that. Some of the readers did not install SQL Server 2012 or some did not have good machine to recreate the big table involved in the demo. For the same reason, I have created small video for that. I have written two more article on columstore index. Please read them as followup to the video: SQL SERVER – How to Ignore Columnstore Index Usage in Query SQL SERVER – Updating Data in A Columnstore Index Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, PostADay, SQL, SQL Authority, SQL Index, SQL Performance, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology, Video

  • SQLAuthority News – #TechEdIn – TechEd India 2012 Memories and Photos

    - by pinaldave
    TechEd India 2012 was held in Bangalore last March 21 to 23, 2012. Just like every year, this event is bigger, grander and inspiring. Pinal Dave at TechEd India 2012 Family Event Every single year, TechEd is a special affair for my entire family.  Four months before the start of TechEd, I usually start to build the mental image of the event. I start to think  about various things. For the most part, what excites me most is presenting a session and meeting friends. Seriously, I start thinking about presenting my session 4 months earlier than the event!  I work on my presentation day and night. I want to make sure that what I present is accurate and that I have experienced it firsthand. My wife and my daughter also contribute to my efforts. For us, TechEd is a family event, and the two of them feel equally responsible as well. They give up their family time so I can bring out the best content for the Community. Pinal, Shaivi and Nupur at TechEd India 2012 Guinea Pigs (My Experiment Victims) I do not rehearse my session, ever. However, I test my demo almost every single day till the last moment that I have to present it already. I sometimes go over the demo more than 2-3 times a day even though the event is more than a month away. I have two “guinea pigs”: 1) Nupur Dave and 2) Vinod Kumar. When I am at home, I present my demos to my wife Nupur. At times I feel that people often backup their demo, but in my case, I have backup demo presenters. In the office during lunch time, I present the demos to Vinod. I am sure he can walk my demos easily with eyes closed. Pinal and Vinod at TechEd India 2012 My Sessions I’ve been determined to present my sessions in a real and practical manner. I prefer to present the subject that I myself would be eager to attend to and sit through if I were an audience. Just keeping that principle in mind, I have created two sessions this year. SQL Server Misconception and Resolution Pinal and Vinod at TechEd India 2012 We believe all kinds of stuff – that the earth is flat, or that the forbidden fruit is apple, or that the big bang theory explains the origin of the universe, and so many other things. Just like these, we have plenty of misconceptions in SQL Server as well. I have had this dream of co-presenting a session with Vinod Kumar for the past 3 years. I have been asking him every year if we could present a session together, but we never got it to work out, until this year came. Fortunately, we got a chance to stand on the same stage and present a single subject.  I believe that Vinod Kumar and I have an excellent synergy when we are working together. We know each other’s strengths and weakness. We know when the other person will speak and when he will keep quiet. The reason behind this synergy is that we have worked on 2 Video Learning Courses (SQL Server Indexes and SQL Server Questions and Answers) and authored 1 book (SQL Server Questions and Answers) together. Crowd Outside Session Hall This session was inspired from the “Laurel and Hardy” show so we performed a role-playing of those famous characters. We had an excellent time at the stage and, for sure, the audience had a wonderful time, too. We had an extremely large audience for this session and had a great time interacting with them. Speed Up! – Parallel Processes and Unparalleled Performance Pinal Dave at TechEd India 2012 I wanted to approach this session at level 400 and I was very determined to do so. The biggest challenge I had was that this was a total of 60 minutes of session and the audience profile was very generic. I had to present at level 100 as well at 400. I worked hard to tune up these demos. I wanted to make sure that my messages would land perfectly to the minds of the attendees, and when they walk out of the session, they could use the knowledge I shared on their servers. After the session, I felt an extreme satisfaction as I received lots of positive feedback at the event. At one point, so many people rushed towards me that I was a bit scared that the stage might break and someone would get injured. Fortunately, nothing like that happened and I was able to shake hands with everybody. Pinal Dave at TechEd India 2012 Crowd rushing to Pinal at TechEd India 2012 Networking This is one of the primary reasons many of us visit the annual TechEd event. I had a fantastic time meeting SQL Server enthusiasts. Well, it was a terrific time meeting old friends, user group members, MVPs and SQL Enthusiasts. I have taken many photographs with lots of people, but I have received a very few back. If you are reading this blog and have a photo of us at the event, would you please send it to me so I could keep it in my memory lane?

  • Ms Build publishing vs Visual Studio IDE publishing

    - by reggie
    I am currently working on ms build to publish my winform application based on the environment selected (Dev or Prod). I am using Ms Build Community Task and referencing this article to achieve this purpose. I had a few theoretical doubts based on publishing application. 1) Is there any difference in publishing through the visual studio ide and msbuild? 2) What do most developers prefer to use and why? 3) What are the advantages of using MsBuild to publish an application as compared to publishing through the visual studio IDE? 4) What is faster? I am using a .net 3.5 winform application developed in Csharp and my question is pertaining to clickonce windows applications only. Please help me clear these doubts

  • Coders For Charities

    Last weekend I had the opportunity to give back to the community doing what I love. As geeks we dont usually have this opportunity. The event is called Coders 4 Charities (C4C) and its a grueling weekend of coding for nearly 30 hours over the weekend. When you finish you get to present to the charity and all of the other groups what you have completed. From the site: Coders For Charities is a 3-day charity event that pairs charities and local software developers.

  • Oracle... and InfiniBand.

    - by jenny.gelhausen
    Beginning Sunday, 14th March 2010 the OpenFabrics Alliance has been hosting its annual conference in Sonoma, California. On Monday morning, Tim Shetler - VP of Product Management at Oracle - addressed a conference room full to the brim with the industry's InfiniBand luminaries. That same afternoon, Sumanta Chatterjee, Senior Director of Development at Oracle, was publicly lauded by moderator Bill Boas for being a long-standing, pivotal driver and crucial member of the community. A testament to InfiniBand's building momentum, it is no surprise to find it at the core of Oracle's flagship product, the Sun Oracle Database Machine. var gaJsHost = (("https:" == document.location.protocol) ?

  • Redehost Transforms Cloud & Hosting Services with MySQL Enterprise Edition

    - by Mat Keep
    RedeHost are one of Brazil's largest cloud computing and web hosting providers, with more than 60,000 customers and 52,000 web sites running on its infrastructure. As the company grew, Redehost needed to automate operations, such as system monitoring, making the operations team more proactive in solving problems. Redehost also sought to improve server uptime, robustness, and availability, especially during backup windows, when performance would often dip. To address the needs of the business, Redehost migrated from the community edition of MySQL to MySQL Enterprise Edition, which has delivered a host of benefits: - Pro-active database management and monitoring using MySQL Enterprise Monitor, enabling Redehost to fulfil customer SLAs. Using the Query Analyzer, Redehost were able to more rapidly identify slow queries, improving customer support - Quadrupled backup speed with MySQL Enterprise Backup, leading to faster data recovery and improved system availability - Reduced DBA overhead by 50% due to the improved support capabilities offered by MySQL Enterprise Edition. - Enabled infrastructure consolidation, avoiding unnecessary energy costs and premature hardware acquisition You can learn more from the full Redehost Case Study Also, take a look at the recently updated MySQL in the Cloud whitepaper for the latest developments that are making it even simpler and more efficient to develop and deploy new services with MySQL in the cloud

  • New Replication, Optimizer and High Availability features in MySQL 5.6.5!

    - by Rob Young
    As the Product Manager for the MySQL database it is always great to announce when the MySQL Engineering team delivers another great product release.  As a field DBA and developer it is even better when that release contains improvements and innovation that I know will help those currently using MySQL for apps that range from modest intranet sites to the most highly trafficked web sites on the web.  That said, it is my pleasure to take my hat off to MySQL Engineering for today's release of the MySQL 5.6.5 Development Milestone Release ("DMR"). The new highlighted features in MySQL 5.6.5 are discussed here: New Self-Healing Replication ClustersThe 5.6.5 DMR improves MySQL Replication by adding Global Transaction Ids and automated utilities for self-healing Replication clusters.  Prior to 5.6.5 this has been somewhat of a pain point for MySQL users with most developing custom solutions or looking to costly, complex third-party solutions for these capabilities.  With 5.6.5 these shackles are all but removed by a solution that is included with the GPL version of the database and supporting GPL tools.  You can learn all about the details of the great, problem solving Replication features in MySQL 5.6 in Mat Keep's Developer Zone article.  New Replication Administration and Failover UtilitiesAs mentioned above, the new Replication features, Global Transaction Ids specifically, are now supported by a set of automated GPL utilities that leverage the new GTIDs to provide administration and manual or auto failover to the most up to date slave (that is the default, but user configurable if needed) in the event of a master failure. The new utilities, along with links to Engineering related blogs, are discussed in detail in the DevZone Article noted above. Better Query Optimization and ThroughputThe MySQL Optimizer team continues to amaze with the latest round of improvements in 5.6.5. Along with much refactoring of the legacy code base, the Optimizer team has improved complex query optimization and throughput by adding these functional improvements: Subquery Optimizations - Subqueries are now included in the Optimizer path for runtime optimization.  Better throughput of nested queries enables application developers to simplify and consolidate multiple queries and result sets into a single unit or work. Optimizer now uses CURRENT_TIMESTAMP as default for DATETIME columns - For simplification, this eliminates the need for application developers to assign this value when a column of this type is blank by default. Optimizations for Range based queries - Optimizer now uses ready statistics vs Index based scans for queries with multiple range values. Optimizations for queries using filesort and ORDER BY.  Optimization criteria/decision on execution method is done now at optimization vs parsing stage. Print EXPLAIN in JSON format for hierarchical readability and Enterprise tool consumption. You can learn the details about these new features as well all of the Optimizer based improvements in MySQL 5.6 by following the Optimizer team blog. You can download and try the MySQL 5.6.5 DMR here. (look under "Development Releases")  Please let us know what you think!  The new HA utilities for Replication Administration and Failover are available as part of the MySQL Workbench Community Edition, which you can download here .Also New in MySQL LabsAs has become our tradition when announcing DMRs we also like to provide "Early Access" development features to the MySQL Community via the MySQL Labs.  Today is no exception as we are also releasing the following to Labs for you to download, try and let us know your thoughts on where we need to improve:InnoDB Online OperationsMySQL 5.6 now provides Online ADD Index, FK Drop and Online Column RENAME.  These operations are non-blocking and will continue to evolve in future DMRs.  You can learn the grainy details by following John Russell's blog.InnoDB data access via Memcached API ("NotOnlySQL") - Improved refresh of an earlier feature releaseSimilar to Cluster 7.2, MySQL 5.6 provides direct NotOnlySQL access to InnoDB data via the familiar Memcached API. This provides the ultimate in flexibility for developers who need fast, simple key/value access and complex query support commingled within their applications.Improved Transactional Performance, ScaleThe InnoDB Engineering team has once again under promised and over delivered in the area of improved performance and scale.  These improvements are also included in the aggregated Spring 2012 labs release:InnoDB CPU cache performance improvements for modern, multi-core/CPU systems show great promise with internal tests showing:    2x throughput improvement for read only activity 6x throughput improvement for SELECT range Read/Write benchmarks are in progress More details on the above are available here. You can download all of the above in an aggregated "InnoDB 2012 Spring Labs Release" binary from the MySQL Labs. You can also learn more about these improvements and about related fixes to mysys mutex and hash sort by checking out the InnoDB team blog.MySQL 5.6.5 is another installment in what we believe will be the best release of the MySQL database ever.  It also serves as a shining example of how the MySQL Engineering team at Oracle leads in MySQL innovation.You can get the overall Oracle message on the MySQL 5.6.5 DMR and Early Access labs features here. As always, thanks for your continued support of MySQL, the #1 open source database on the planet!

  • Scripting a sophisticated RTS AI with Lua

    - by T. Webster
    I'm planning to develop a somewhat sophisticated RTS AI (eg see BWAPI). have experience programming, but none in game development, so it seems easiest to start by scripting the AI of an existing game I've played, Warhammer 40k: Dawn of War (2004). As far as I can tell, the game AI is scripted with some variant of Lua (by the file extension .ai or .scar). The online documentation is sparse and the community isn't active anymore. I'd like to get some idea of the difficulty of this undertaking. Is it practical with a scripting language like Lua to develop a RTS AI that includes FSMs, decision trees, case-based reasoning, and transposition tables? If someone has any experience scripting Dawn of War, that would also help.

  • How can I improve overall system performance?

    - by Decio Lira
    What are your tips for improving overall system performance on ubuntu? Inspired by this question I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster. This is not meant to be application specific (e.g. make firefox load pages faster), but system wide. Preferably 1 tip per answer, with enough detail for people to implement it. A couple of mine would be: Install Preload (via Software Center or sudo apt-get install preload); Change Swappiness value - "which controls the degree to which the kernel prefers to swap when it tries to free memory"; What are yours? PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box.

  • GWB: 5 yr anniversary

    - by Theo Moore
    Wow, just realized it's my 5 year anniverary on GeeksWithBlogs. Hard to believe so much time has passed. I paged back through some of my early posts, curious what sort of things about which I used to post. It's also interesting to see how my focus has changed and what really hasn't. I was also reminded that Chris Williams and I have been friends for that long. I don't blog nearly as often now as I used to do, but I still really like the GWB community, and I am honoured to be allowed to continue to be a part of it. Another 5 years ahead (or more), I hope. :-)

  • Switching from Visual Studio to Eclipse [closed]

    - by Jouke van der Maas
    I've been using Visual Studio for about 6 years now, which is enough time to know most useful keyboard shortcuts and little features. I recently had to switch to Eclipse and java for school, and now I'm constantly searching for the right keys to press. I have searched around for a definitve guide on this, but I couldn't find any. Here's what I want to know: For any feature in Visual Studio, what is the equivalent feature in Eclipse called and what is it's default keyboard shortcut? Are there any things that work very differently in Eclipse, that one might misunderstand or do wrong at first when switching? Are there features in Visual Studio that Eclipse does not have, and is there a workaround? I hope we can create a guide to make life easier for future developers that have to make this switch. You can answer any of the three questions above (no need to do all three), and multiple per answer if you want. I can't mark questions as community wiki anymore, but I do think that's appropriate here.

    I'm trying to setup a network service for running saned (running the sane-test backend) on Ubuntu 12.10, running it on a virtualbox. I followed the directions found here: https://help.ubuntu.com/community/ScanningHowTo and i got to the point where if i use a front-end like xsane, or use the command scanimage -d test i get the desired behaviour. (i get the test image). But when i try to use the network demon to access the backend (from the localhost) i get Failed to connect. I used telnet on 127.0.0.1 6566 and i got the following error: saned: symbol lookup error: saned: undefined symbol: sanei_w_init I'm a linux newbie, so i could be making some stupid mistake.

  • Single python file distribution: module or package?

    - by DanielSank
    Suppose I have a useful python function or class (or whatever) called useful_thing which exists in a single file. There are essentialy two ways to organize the source tree. The first way uses a single module: - setup.py - README.rst - ...etc... - foo.py where useful_thing is defined in foo.py. The second strategy is to make a package: - setup.py - README.rst - ...etc... - foo |-module.py |-__init__.py where useful_thing is defined in module.py. In the package case __init__.py would look like this from foo.module import useful_thing so that in both cases you can do from foo import useful_thing. Question: Which way is preferred, and why? EDIT: Since user gnat says this question is poorly formed, I'll add that the official python packaging tutorial does not seem to comment on which of the methods described above is the preferred one. I am explicitly not giving my personal list of pros and cons because I'm interested in whether there is a community preferred method, not generating a discussion of pros/cons :)

  • Permission denied after creating home partition

    - by Magnus
    I have recently created a separate home partition following this tutorial https://help.ubuntu.com/community/Partitioning/Home/Moving. Since I’m still a newbie in the Linux (struggling to learn) I felt happy when every thing seemed to work smooth. How ever, I realised after a while that I had lost all permission to my subfolders in the my home folder. I still can read/write the files placed directly in /home/magnus but I'm denied access to any of the subfolders. I just realised one more disturbing thing, probably related to home-partition story above: When I try cd ~/Music/ I get the message bash: cd: /home/magnus/Music/: Permission denied When I try: sudo cd ~/Music/ I get the result sudo: cd: command not found Seems strange that the cd command have been lost? What have I done wrong and is there a way to fix this? btw: I use Ubuntu 12.04 LTS Thanks for all the help! Magnus

    I'm developing a big community/forum website and I'd like to upload my code to GitHub to have at least some sort of version control over it (because I have nothing other than a .rar file as a backup, not even SVN), to let others contribute to the project, and also perhaps using it to let my potential future employers see some of my code as some sort of curriculum. But what I'm wondering now, and I'm suprised I haven't seen anyone mention it before is the security aspect of it. Isn't publishing the code of a website a HUGE security hole? Is like giving a potential hacker or anyone who would like to find any potential exploit possible, even considering that the critical files aren't uploaded (database passwords, authentication scripts, etc.). Of course that there are millions of projects uploaded to GitHub and no one will find mine just 'by chance'. But if they look for it, it would indeed be there. Bottomline: my problem is not about copyright or licenses, but others finding exploits in my website. I'm I missing something here?
