  • 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? SQL Track Speaker: Jacob and Pinal at TechEd India 2012 SQL Community: Pinal, Tejas, Nakul, Jacob, Balmukund, Manas, Sudeepta, Sahal at TechEd India 2012 Star Speakers: Amit and Balmukund at TechEd India 2012 TechED Rockstars: Nakul, Tejas and Pinal at TechEd India 2012 I guess TechEd is a mix of family affair and culture for me!

    Respected all, As many know testing can be mainly classified into manual and automated testing. With regard to this certain questions come to mind. Hope you can help... They include: What is the basic difference between the two types of testing? What are the elements of challenges involved in both manual and automated testing? What are the different skill sets required by a software tester for manual and automated testing respectively? What are the different job prospects and growth opportunities among software testers who do manual testing automated testing respectively? Is manual testing under rated to automated testing in anyway(s)? If yes, kindly specify the way. How differently are the manual testers treated in comparison to automated testers in the corporate world?( If they truly are differentiated in any terms as such ) I hope you can share your knowledge in answering these questions..

  • Can you over-normalize?

    - by drsql
    Now, don’t get too excited and grab your pitchforks and torches. Clearly, it is extremely possible to overdo something in the design, but very often normalization takes the rap as being the culprit. In my “Database Design Fundamentals” presentation, one of my favorite things to do is ask “What is the most important normal form?” 9 out of 10 times, someone answers “Third”. When I ask what they have against fourth, the usually say that it makes the database work too slow. But when they find out that...(read more)

  • Configuring 12voip with a sip softphone in Ubuntu

    - by Joey
    I want to change my work PC to Ubuntu but one thing is in my way... We use 12voip since we didn't find lower calling rates in Europe. The thing is 12voip doesn't have a Linux program :-(. I tried to set it up with instructions from this page (under 'Software configuration') with almost all clients that the software center of Ubuntu offers, but the best results i got to had a lot of echo. Now i must admit this echo exists also with the Windows version of the program, but there- once you use headphones its gone, while on the Ubuntu sip phones it stays and its worst in general. I don't know if my problem has to do with codecs or something else, and i was hoping someone can help check it and tell me which sip phone i can work with, and instructions on how to configure it correctly. Btw i tried Google, and all i could find were questions like mine or similar, no good answers. Thanks!

  • As a game developer, which data structure use for develop the game? [duplicate]

    - by Rizwanabbasi
    This question already has an answer here: When should vector/list be used? 5 answers We are developing a game for bank robbery. The game plots a bank robbery. Lots of people witness that robbery. Our game will load the lists of suspected offenders while the players (witnesses) will have to identify the offenders of this robbery. Game should load list of offenders to identify the one as quickly as possible. Admin can add/remove offenders in the lists and two or more lists of offenders can also be merged into one (to show it to the player). As a game developer, which data structure we should use for develop the game? Justify your selection with solid arguments. Remember the most critical requirement is that the list should load super fast.

  • Why use apt-get upgrade instead of apt-get dist-upgrade?

    - by jimirings
    I usually use apt-get update && apt-get upgrade to run my updates and upgrades instead of the GUI because it seems to run more quickly. However, I've noticed lately that I often get a message that one of my upgrades was held back. I then usually run dist-upgrade to run it through and it works fine. As far as I can tell after reading this question and its answers, dist-upgrade does all the same things and then some. So, my question is: Why use apt-get upgrade at all? Why not use apt-get dist-upgrade all the time? Why does apt-get upgrade even exist?

  • How do I let programmers know something useful?

    - by Shane
    Quite often I go through pain to discover how to do something useful, in this case how to get PHP running on Google App Engine without the 'resin.jar too big' problem, but I have nowhere to let people know. In this particular case, the web answers were incomplete, outdated or plain wrong. I could create a blog, but it's overkill. I just want let programmers know a quick solution/approach. I'm not sure it's the done thing to ask a question and then answer it. In short, it'd be nice to be able to just dump a sort of combined question/answer/snippet, then let others comment as usual, shoot it down, like it, whatever. How do the rest of you approach this? Cheers, Shane

  • Running your own GAE server

    - by h2g2java
    The question http://stackoverflow.com/questions/2505265/how-difficult-is-it-to-migrate-away-from-google-app-engine triggered me to think about this issue again. I have read of someone running, production-wise, Google app engine development version on their own server. My questions are: Are there any security issues running GAE development on your own server in production mode and exposing it to the www? If so how to mitigate them? Can GAE dev be run on Amazon? Is it possible to port my GAE apps running on Google servers to a GAE running on Amazon, without code changes, but without changing any reference in using other gdata services such as google docs, youtube, gmail, etc. How to configure GAE dev server to use my own hadoop? Or to use Amazon's hadoop?

  • Fullscreen Still Has Taskbars at Top and Bottom

    - by MugenDraco
    I'm using Ubuntu 12.04 and running the Gnome Classic desktop. Whenever I go fullscreen, the taskbars at the top and bottom which hold the menus, notifications, etc. are still visible. This only happens when I'm in a browser or trying to play a game. I've tried it in both Firefox and Chromium, and get the same result no matter which one I use. Videos I watch using VLC however do not have the bars at the top and bottom. I found only one post about this in the questions, but there were no answers that worked for me. I wasn't sure if commenting my problem into the 5 month old post would move it to the top where it could be seen, so I made this one.

  • 301 redirect www to non-www [duplicate]

    - by Claudiu
    This question already has an answer here: Removing non-www support 4 answers I understand that it is better to make a 301 redirect to make sure that all your links are seen the same on Google. Until now I always used erasmus-plus.ro without the www. for my website. Is it ok to make a redirect from www. to non-www. From my search on Google all users spoke about it the other way around. And somewhere I read that redirects are not good for seo. Is 301 an exception?

  • Using Visual Studio as a Task-Focused IDE

    - by Jay Stevens
    Are there patterns or libraries or any official Microsoft SDK for using Visual Studio as a specifically Task-Focused UI? For example, both Revolution R (IDE for the R language) and SQL 2012 (and I think SQL 2008 and possibly 2005) use Visual Studio as the underlying IDE framework. Is there an officially supported SDK and/or examples/samples for doing this type of thing? I am building a language Parser for an existing language - whose only available IDE is INSANELY expensive - using Irony (and eventually will generate a Language Service as well). Any direct or indirect suggestions/answers are appreciated.

  • Making an interface for input in C - How?

    - by tloszk
    I have a big question. I started to develop a simple 3D engine (or should I call it framework?). I use OpenGL for rendering and it is developed for Windows. It is all written in C. But I don't know, how to write an "interface" for the keyboard/mouse input. I would like to keep it as simple as possible and nice - what the Win32 "native" input system is not. If anyone has suggestions about the topic, please, tell me. Thanks for everyone, who answers to my question!

  • SQL SERVER – Columnstore Index and sys.dm_db_index_usage_stats

    - by pinaldave
    As you know I have been writing on Columnstore Index for quite a while. Recently my friend Vinod Kumar wrote about  SQL Server 2012: ColumnStore Characteristics. A fantastic read on the subject if you have yet not caught up on that subject. After the blog post I called him and asked what should I write next on this subject. He suggested that I should write on DMV script which I have prepared related to Columnstore when I was writing our SQL Server Questions and Answers book. When we were writing this book SQL Server 2012 CTP versions were available. I had written few scripts related to SQL Server columnstore Index. I like Vinod’s idea and I decided to write about DMV, which we did not cover in the book as SQL Server 2012 was not released yet. We did not want to talk about the product which was not yet released. The first script which I had written was with DMV - sys.column_store_index_stats. This DMV was displaying the statistics of the columnstore indexes. When I attempted to run it on SQL Server 2012 RTM it gave me error suggesting that this DMV does not exists. Here is the script which I ran: SELECT * FROM sys.column_store_index_stats; It generated following error: Msg 208, Level 16, State 1, Line 1 Invalid object name ‘column_store_index_stats’. I was pretty confident that this DMV was available when I had written the scripts. The next reaction was to type ‘sys.’ only in SSMS and wait for intelisense to popup DMV list. I scrolled down and noticed that above said DMV did not exists there as well. Now this is not bug or missing feature. This was indeed something can happen because the version which I was practicing was early CTP version. If you go to the page of the DMV here, it clearly stats notice on the top of the page. This documentation is for preview only, and is subject to change in later releases. Now this was not alarming but my next thought was if this DMV is not there where can I find the information which this DMV was providing. Well, while I was thinking about this, I noticed that my another friend Balmukund Lakhani was online on personal messenger. Well, Balmukund is “Know All” kid. I have yet to find situation where I have not got my answers from him. I immediately pinged him and asked the question regarding where can I find information of ‘column_store_index_stats’. His answer was very abrupt but enlightening for sure. Here is our conversation: Pinal: Where can I find information of column_store_index_stats? Balmukund: Assume you have never worked with CTP before and now try to find the information which you are trying to find. Honestly  it was fantastic response from him. I was confused as I have played extensively with CTP versions of SQL Server 2012. Now his response give me big hint. I should have not looked for DMV but rather should have focused on what I wanted to do. I wanted to retrieve the statistics related to the index. In SQL Server 2008/R2, I was able to retrieve the statistics of the index from the DMV - sys.dm_db_index_usage_stats. I used the same DMV on SQL Server 2012 and it did retrieved the necessary information for me. Here is the updated script which gave me all the necessary information I was looking for. Matter of the fact, if I have used my earlier SQL Server 2008 R2 script this would have just worked fine. SELECT DB_NAME(Database_ID) DBName, SCHEMA_NAME(schema_id) AS SchemaName, OBJECT_NAME(ius.OBJECT_ID) ObjName, i.type_desc, i.name, user_seeks, user_scans, user_lookups, user_updates,* FROM sys.dm_db_index_usage_stats ius INNER JOIN sys.indexes i ON i.index_id = ius.index_id AND ius.OBJECT_ID = i.OBJECT_ID INNER JOIN sys.tables t ON t.OBJECT_ID = i.OBJECT_ID GO Let us see the resultset of above query. You will notice that column Type_desc describes the type of the index. You can additionally write WHERE condition on the column and only retrieve only selected type of Index.

  • Thoughts on moving to Maven in an enterprise environment

    - by Josh Kerr
    I'm interested in hearing from those who either A) use Maven in an enterprise environment or B) tried to use Maven in an enterprise environment. I work for a large company that is contemplating bringing in Maven into our environment. Currently we use OpenMake to build/merge and home-grown software to deploy code to 100+ servers running various platforms (eg. WAS and JBoss). OpenMake works fine for us however Maven does have some ideal features, most importantly being dependency management, but is it viable in a large environment? Also what headaches have/did you incur, if any, in maintaining a Maven environment. Side note, I've read http://stackoverflow.com/questions/861382/why-does-maven-have-such-a-bad-rep, http://stackoverflow.com/questions/303853/what-are-your-impressions-of-maven, and a few other posts. It's interesting seeing the split between developers.

  • Ubuntu 12.04 doesn't start after installing with LiveUSB

    I need help! I installed Ubuntu with my LiveUSB, and it said restart to use your system, so I restarted. Now I am just stuck in a completely black screen with a blinking _ I'm already waiting 10 minutes for something to happen, but there's nothing. I don't know what the problem could be, but maybe the message I got during installation that said 'APT couldn't be configured, so no additional apps will be installed' was the problem? I'm still waiting.. Fast answers please :) thanks.

  • Exporting the frames in a Flash CS5.5 animation and possibly creating the spritesheet

    - by Adam Smith
    Some time ago, I asked a question here to know what would be the best way to create animations when making an Android game and I got great answers. I did what people told me there by exporting each frame from a Flash animation manually and creating the spritesheet also manually and it was very tedious. Now, I changed project and this one is going to contain a lot more animations and I feel like there has to be a better way to to export each frame individually and possibly create my spritesheets in an automated manner. My designer is using Flash CS5.5 and I was wondering if all of this was possible, as I can't find an option or code examples on how to save each frame individually. If this is not possible using Flash, please recommend me another program that can be used to create animations without having to create each frame on its own. I'd rather keep Flash as my designer knows how to use it and it's giving great results.

  • CodeGolf: Brothers

    - by John McClane
    Hi guys, I just finished participating in the 2009 ACM ICPC Programming Conest in the Latinamerican Finals. These questions were for Brazil, Bolivia, Chile, etc. My team and I could only finish two questions out of the eleven (not bad I think for the first try). Here's one we could finish. I'm curious to seeing any variations to the code. The question in full: ps: These questions can also be found on the official ICPC website available to everyone. In the land of ACM ruled a greeat king who became obsessed with order. The kingdom had a rectangular form, and the king divided the territory into a grid of small rectangular counties. Before dying the king distributed the counties among his sons. The king was unaware of the rivalries between his sons: The first heir hated the second but not the rest, the second hated the third but not the rest, and so on...Finally, the last heir hated the first heir, but not the other heirs. As soon as the king died, the strange rivaly among the King's sons sparked off a generalized war in the kingdom. Attacks only took place between pairs of adjacent counties (adjacent counties are those that share one vertical or horizontal border). A county X attacked an adjacent county Y whenever X hated Y. The attacked county was always conquered. All attacks where carried out simultanously and a set of simultanous attacks was called a battle. After a certain number of battles, the surviving sons made a truce and never battled again. For example if the king had three sons, named 0, 1 and 2, the figure below shows what happens in the first battle for a given initial land distribution: INPUT The input contains several test cases. The first line of a test case contains four integers, N, R, C and K. N - The number of heirs (2 <= N <= 100) R and C - The dimensions of the land. (2 <= R,C <= 100) K - Number of battles that are going to take place. (1 <= K <= 100) Heirs are identified by sequential integers starting from zero. Each of the next R lines contains C integers HeirIdentificationNumber (saying what heir owns this land) separated by single spaces. This is to layout the initial land. The last test case is a line separated by four zeroes separated by single spaces. (To exit the program so to speak) Output For each test case your program must print R lines with C integers each, separated by single spaces in the same format as the input, representing the land distribution after all battles. Sample Input: Sample Output: 3 4 4 3 2 2 2 0 0 1 2 0 2 1 0 1 1 0 2 0 2 2 2 0 0 1 2 0 0 2 0 0 0 1 2 2 Another example: Sample Input: Sample Output: 4 2 3 4 1 0 3 1 0 3 2 1 2 2 1 2

  • Transferring at a large software company: ask boss before or after?

    - by ZNZ
    Out of college I joined a large, well-known software company's consulting arm. I've gained lots of experience with some of the company's products but would like to start doing more development work rather than implementation work (traveling less would be nice, too!). The company has some product development positions that I think I could be a good fit for, but I'm unsure of how to bring it up with my manager. After a bit Googling, there are many conflicted answers on how best to handle transferring departments. When should I tell my current manager that I am interested in pursuing other positions in the company? Before or after applying?

  • Keyring Password, Unity in 11.10

    - by Collin Owens
    Login to 11.10 I input my password and shortly afterward I am asked for a keyring password. I realize that I was asked for this during installation (second time lucky!) and I did enter a password (what a mistaka to maka). This now entails my having to input the keyring password on every boot up! Looking at previous answers it would seem that the applications - accesories - password and encryption keys - was the suggested route. However I assume that was in Gnome (At this stage I look back in fondness!!!) Certainly, I don't get the same route in Unity! I saw a reference to seahorse in a terminal - but this results in several error reports and a sub windows which does not seem to open. The objective in this exercise is to log in using the login password and not also the keyring password! any help would be appreciated - thank you
