• SQL Authority News – FalafelCON 2014: 2 days with the Best Developers in the World

  - by Pinal Dave

  I love presenting at various forums on various technologies. I am extremely excited that I got invited to speak at Falafel Conference 2014 in San Francisco. I will present two technology sessions on SQL Server. If you are into web development or if you just want to attend a conference with the best of the industry speakers, this may be the right conference for you. What set apart this conference from other conference is technology presented as well as speakers. Usually one has to attend very expensive and high scale event when they have to hear good speakers. At this conference, you will find quite a many industry legends are available to present on the bleeding edge technology. Here are few of the reasons why I believe you should attend this conference: Choose from four tracks covering Web, Mobile development and testing, Sitefinity, and Automated Testing, or attend sessions from all four! Learn from the best developers and testers in the business in an intimate setting. Surround yourself with your peers and the opportunity to network Learn about the latest platforms and technologies including Kendo UI, AngularJS, ASP.NET MVC, WebAPI, and more! Here are the details for the sessions which I am going to present at Falafel Conference. Secrets of SQL Server: Database Worst Practices Abstract: Chances are you have heard, or even uttered, this expression. This demo-oriented session will show many examples where database professionals were dumbfounded by their own mistakes, and could even bring back memories of your own early DBA days. The goal of this session is to expose the small details that can be dangerous to the production environment and SQL Server as a whole, as well as talk about worst practices and how to avoid them. Shedding light on some of these perils and the tricks to avoid them may even save your current job. After attending this session, Developers will only need 60 seconds to improve performance of their database server in their SharePoint implementation. We will have a quiz during the session to keep the conversation alive. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Additionally, all attendees of the session will have access to learning material presented in the session. The Unsung Hero Abstract: Slow Running Queries are the most common problem that developers face while working with SQL Server. While it is easy to blame the SQL Server for unsatisfactory performance, however the issue often persists with the way queries have been written, and how Indexes has been set up. The session will focus on the ways of identifying problems that slow down SQL Server, and Indexing tricks to fix them. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. Register Now! I have learned from the Falafel Team that they are running out of tickets and soon they will close the registration.  For next 10 days the price for the registration is only USD 149. Trust me, you can’t get such a world class training and networking opportunity at such a low price. Click to Register Here!

• SEO, Social Media & Skinny Jeans

  No longer is social media just the "cool thing" to do - like rocking an 80's inspired flat top hairdo in 2010. Social networking now has a definitive effect on your SEO efforts, and as such, it must be monitored closely. While previous social networking efforts were generally tied to connecting with a business's customer base, Google is now including real-time social media into their search results - resulting in increased (and practically effortless) SEO opportunities.

• How do I write code that doesn't suck? [closed]

  - by Afnan

  My friends and I would like to write a C# desktop application, and would like some guidance on how to make sure the code base is professional and well-kept. Should we use classes or interfaces for our inheritance patterns (which is better)? What are the best practices for professional applications? How do we know what sloppy code looks like, and how do we avoid creating sloppy code? Are there any best practices regarding the design of Winforms applications?

• SQLAuthority News – Live Virtual Classroom New Trend in Technology

  - by nupurdave

  This blog post is by Nupur Dave, who is housewife and works from home. Changing times and a super busy lifestyle have rendered most of us powerless when it comes to doing what we love to do. I feel that a man never ceases to learn and his sole aim is to seek knowledge, and keep growing. However, our tight schedules and packed calendars mean that we really have to struggle to take some time out and follow the path towards learning. Like all working professionals with a family to take care of, I hardly found time to pursue my interests. However, it was getting increasingly important for me to upgrade my skills, not only for my personal quest for knowledge but to also substantiate my professional standing. When I came to know about Koenig Live Virtual Classroom from friends, it piqued my interest. I felt like it was the answer to all my concerns. Without wasting a single minute, I contacted Koenig for a demo class. Here are some of the highlights of Koenig LVC which instantly struck a chord in me: Online Training – Koenig offers 1-on-1 Online Training with the instructor at the other end. Doesn’t matter where I am sitting, in my office or at home, I can connect to my trainer from anywhere. Flexible Timings – The most comfortable part is you get to choose the time that suits you best. Economical -  No need to travel a thousand miles, the experts are right here on your computer screen. So no extra cost of travel, lodging and meals. 24X7 Lab Access: This is again a great feature that proved to be very beneficial in gaining a practical understanding of the subject. Powered by a data center, this facility offers students much to look forward to. 300+ Full Time Certified Experts: Be assured that you are learning from the best people in the industry. Customized Courses: Course material and training delivery is completely customized to suit your specific requirements. Official Courseware: The instructor teaches from official courseware of the vendor, depending on which course you have applied for – be it Microsoft, Cisco, Oracle or any other certification. Take Exam from Anywhere: Post completion of your IT training, you can take your certification exam from anywhere. Again, no need to travel a thousand miles to earn certified status. No Pre-Recorded Sessions: For those who still need clarification, it will be a live online classroom with trainers instructing you in real time. So you won’t get any surprises of getting pre-recorded sessions in place of your live instructor. Koenig’s Live Virtual Classroom methodology greatly exceeded my expectations. The instructor was highly skilled and very professional. I had concerns about the quality of AV on the computer screen, and whether I’ll be able to understand each topic in detail. However, the quality of video and sound, and the learning methodology used was impeccable. If you’re also facing time crunch and other commitment issues which are getting in the way of your professional development, LVC is the best solution to learn and grow.

• Need a bounding box for CCSprite that includes all children/subchildren

  - by prototypical

  I have a CCSprite that has CCSprite children, and those CCSprite children have CCSprite children. The contentSize property doesn't seem to include all children/subchildren, and seems to only work for the base node. I could write a recursive method to traverse a CCSprite for all children/subchildren and calculate a proper boundingbox, but am curious as to if I am missing something and it's possible to get that information without doing so. I'l be a little surprised if such a method doesn't exist, but I can't seem to find it.

• SQL Server v.Next (Denali) : Breaking change to fn_virtualfilestats

  - by AaronBertrand

  Yesterday I posted a general warning about changes to Denali that will potentially break your existing code base, with a strong suggestion to grab the summer CTP as soon as it is available and start testing. I posted an example of a breaking change that will not be documented since it affects a commonly-used but undocumented DBCC command (DBCC LOGINFO), and also mentioned a couple of other changes in passing (). Today it occurred to me that it may be more useful if, when I come across a potential...(read more)

• PASS summit 2013. We do not remember days. We remember moments.

  - by Maria Zakourdaev

    "Business or pleasure?" barked the security officer in the Charlotte International Airport. "I’m not sure, sir," I whimpered, immediately losing all courage. "I'm here for the database technologies summit called PASS”. "Sounds boring. Definitely a business trip." Boring?! He couldn’t have been more wrong. If he only knew about the countless meetings throughout the year where I waved my hands at my great boss and explained again and again how fantastic this summit is and how much I learned last year. One by one, the drops of water began eating away at the stone. He finally approved of my trip just to stop me from torturing him. Time moves as slow as a turtle when you are waiting for something. Time runs as fast as a cheetah when you are there. PASS has come...and passed. It’s been an amazing week. Enormous sqlenergy has filled the city, filled the convention center and the surrounding pubs and restaurants. There were awesome speakers, great content, and the chance to meet most inspiring database professionals from all over the world. Some sessions were unforgettable. Imagine a fully packed room with more than 500 people in awed silence, catching each and every one of Paul Randall's words. His tremendous energy and deep knowledge were truly thrilling. No words can describe Rob Farley's unique presentation style, captivating and engaging the audience. When the precious session minutes were over, I could tell that the many random puzzle pieces of information that his listeners knew had been suddenly combined into a clear, cohesive picture. I was amazed as always by Paul White's great sense of humor and his phenomenal ability to explain complicated concepts in a simple way. The keynote by the brilliant Dr. DeWitt from Microsoft in front of the full summit audience of 5000 deeply listening people was genuinely breathtaking. The entire conference throughout offered excellent speakers who inspired me to absorb the knowledge and use it when I got home. To my great surprise, I found that there are other people in this world who like replication as much I do. During the Birds of a Feather Luncheon, SQL Server MVP Ted Krueger was writing a script for replicating the food to other tables. I learned many things at PASS, and not all of them were about SQL. After three summits, this time I finally got the knack of networking. I actually went up and spoke to people, and believe me, that was not easy for an introvert. But this is what the summit is all about. Sqlpeople. They are the ones who make it such an exciting experience. I will be looking forward to the next year. Till then I have my notes and new ideas. How long was the summit? Thousands of unforgettable moments.

• C++ and SDL resource management for 2D game

  - by KuruptedMagi

  My first question is about stateManagers. I do not use the singleton pattern (read many random posts with various reasons not to use it), I have gameStateManager which runs the pointer cCurrentGameState-render(), etc. I want to make a transitioning game, this engine should ideally cover both a platformer and a bird's eye RPG (with some recoding, I just mean the base engine), both of which will load different levels and events, such as world map, dungeon, shops, etc. So I then thought, rather then having to store all this data within all the states, I would break the engine into gameStates, and playStates... when gameState reaches gameStatePlay(), gameStatePlay simply runs the usual handleInput, logic, and render for the playStates, just as the low level gameStateManager does. This lets me store all the player data within the base playstate class without storing useless data in the gameStates. Now I have added a seperate mapEditor, which uses editorStates from gameStateEditor. Is this too much usage of the gameState concept? It seems to work pretty well for me, so I was wondering if I am too far off a common implementation of this. My second question is on image resources. I have my sprite class with nothing but static members, mainly loadImage, applySurface, and my screen pointer. I also have a map pairing imageName enums with actual SDL_Surface pointers, and one pairing clipNumber enums with a wrapper class for a vector of clips, so that each reference in the map can have different amounts of clips with different sizes. I thought it would be better to store all these images, and screen within one static body, since 20 different goblins all use the same sprite sheet, and all need to print to the same screen, and of course, this way I do not need to pass my screen reference to every little entity. The imageMap seems to work very well, I can even add the ability to search through the map at creation of entity type to see if a particular image at creation, creating if it doesnt exist, and destroying the image if the last entity that needs it was just destroyed. The vectored clip map however, seems to take too long to initialize, so if i run past the state that initializes them to fast, the game crashes <. Plus, the clip map call is half of this line =P SPRITE::applySurface( cEditorMap.cTiles[x][y].iX, cEditorMap.cTiles[x][y].iY, SPRITE::mImages[ IMAGE_TILEMAP ], SPRITE::screen, SPRITE::mImageClips[IMAGE_TILEMAP]->clips.at( cEditorMap.cTiles[x][y].iTileType ) ); Again, do I have the right idea? I like the imageMap, but am I better off with each entity storing its own clips? My last question is about collision detection. I only grasp the basics, will look at per-pixel and circular soon, but how can I determine which side the collision comes from with just the basic square collision detection, I tried breaking each entity into 4 collision zones, but that just gave me problems with walking through walls and the like <. Also, is per-pixel color collision a good way to decide what collision just occured, or is checking multiple colors for multiple entities too taxing each cycle?

• When will java change to 64bit addressing and how can we get there faster?

  - by Ido Tamir

  Having to work with large files now, I would like to know when the java libraries will start switching to long for indexing in their methods. From Inputstreams read(byte[] b, int off, int len) - funnily there is long skip(long) also - to MappedByteBuffer to the basic indexing of arrays and lists, everything is adressed as int. Is there an official plan for enhancment of the libraries? Do initiatives exist to pressure oracle into enhancing the libraries, if there is no official plan yet?

• Develop web site from existing software or cherry pick and use a web framework?

  - by erisco

  A small team and I are tasked with developing a web site. The client has referenced a particular open source project (we'll call it X) when describing some of the features. Because of this, the team wants to start with X and adapt it to satisfy the client. I have looked at X and its code and, in my opinion, it would be unwise. However, my experience is limited, and could really benefit from the insights of others so that I can figure out what I should be asserting as the right direction for the team. My red flags are going up and this is why. X was developed in the earlier days of PHP; 500 line blocks of code are the norm; global variables are abundant; giant switch cases are the norm for switching between which page is shown. There is no clear mapping between URL and where the code for that page sits. From a feature-set standpoint, X is actually software specialized for a different task and has dozens of features we don't need or have use for that come as core assumptions. We will be unable to adapt X through its plugin system. That said, there are a few features which can be mapped, with some modification, to suit our purposes. I believe this is the attraction the team feels. I would feel comfortable if, instead of using X directly, we lifted what is salvageable and useful to us. We can then use that code, and the same 3rd party libraries X is using, in a new code base built on top of a PHP web framework (particularly Agavi, so you understand what I mean by 'web framework'). The web framework gives us a strong MVC structure and provides the common facilities for web development, or adapters to work with 3rd party libraries that do so. We will also have a clean slate feature-wise to work from, which means we can work additively instead of subtractively. Because the code base is better structured, and contains none of what we don't need, it will be easier to document, which is a critical requirement of our client. So to summarize, the team wants to use X, whereas I want to take the bits we can from X and use a web framework instead. I want to bounce this opinion off of other's experiences so that I can be more informed. Thanks for your insight.

• The Benefits of Doing Proper Keyword Research

  First of all, let's get one thing straight: keyword research is the hands down the absolute base for any marketing or search engine optimization campaign. You can't get absolutely anything done without doing proper keyword research first. The simple reason behind this fact is that you will be needing the results provided by keyword services for everything from the actual content of your website, to future search engine optimization campaigns, pay per click campaigns, and so on.

• Turnkey with LightSwitch

  - by Laila

  Microsoft has long wanted to find a replacement for Microsoft Access. The best attempt yet, which is due out in, or before, September is Visual Studio LightSwitch, with which it is said to be as 'easy as flipping a switch' to use Silverlight to create simple form-driven business applications. It is easy to get confused by the various initiatives from Microsoft. No, this isn't WebMatrix. There is no 'Razor', for this isn't meant for cute little ecommerce sites, but is designed to build simple database-applications of the card-box type. It is more clearly a .NET-based solution to the problem that every business seems to suffer from; the plethora of Access-based, and Excel-based 'private' and departmental database-applications. These are a nightmare for any IT department since they are often 'stealth' applications built by the business in the teeth of opposition from the IT Department zealots. As they are undocumented, it is scarily easy to bring a whole department into disarray by decommissioning a PC tucked under a desk somewhere. With LightSwitch, it is easy to re-write such applications in a standard, maintainable, way, using a SQL Server database, deployed somewhere reasonably safe such as Azure. Even Sharepoint or Windows Communication Foundation can be used as data sources. Oracle's ApEx has taken off remarkably well, and has shaken the perception that, for the business user, Oracle must remain a mystic force accessible only to the priests and acolytes. Microsoft, by comparison had only Access, which was first released in 1992, the year of the Madonna conical bustier. It looks just as dated. Microsoft badly needed an entirely new solution to the same business requirement that led to Access's and Foxpro's long-time popularity, but which had the same allure as ApEx. LightSwitch is sound in its ideas, and comfortingly conventional in its architecture. By giving an easy access to SQL Server databases, and providing a 'thumb and blanket' migration path to Access-heads, LightSwitch seems likely to offer a simple way of pulling more Microsoft users into the .NET community. If Microsoft puts its weight behind it, then it will give some glimmer of hope to the many Silverlight developers that Microsoft is capable of seeing through its .NET revolution.

• Why are source control systems still mostly backed with files?

  - by Andy

  It seems that more source control systems still use files as the means of storing the version data. Vault and TFS use Sql Server as their data store, which I would think would be better for data consistency as well as speed. So why is it that SVN, I believe GIT, CVS, etc still use the file system as essentially a database, (I ask this question as we had our SVN server just corrupt itself during a normal commit) instead of using actual database software (MSSQL, Oracle, Postgre, etc)?

• What are the problems with a relatively large common library?

  - by Sam Pearson

  As long as the code in the base library is as loosely coupled as splitting it up into separate libraries, what's the problem? In general, having a lot of assemblies composing a .NET solution is painful.
