  • Interview with Geoff Bones, developer on SQL Storage Compress

    - by red(at)work
    How did you come to be working at Red Gate? I've been working at Red Gate for nine months; before that I had been at a multinational engineering company. A number of my colleagues had left to work at Red Gate and spoke very highly of it, but I was happy in my role and thought, 'It can't be that great there, surely? They'll be back!' Then one day I visited to catch up them over lunch in the Red Gate canteen. I was so impressed with what I found there, that, three days later, I'd applied for a role as a developer. And how did you get into software development? My first job out of university was working as a systems programmer on IBM mainframes. This was quite a while ago: there was a lot of assembler and loading programs from tape drives and that kind of stuff. I learned a lot about how computers work, and this stood me in good stead when I moved over the development in the 90s. What's the best thing about working as a developer at Red Gate? Where should I start? One of the great things as a developer at Red Gate is the useful feedback and close contact we have with the people who use our products, either directly at trade shows and other events or through information coming through the product managers. The company's whole ethos is built around assisting the user, and this is in big contrast to my previous development roles. We aim to produce tools that people really want to use, that they enjoy using, and, as a developer, this is a great thing to aim for and a great feeling when we get it right. At Red Gate we also try to cut out the things that distract and stop us doing our jobs. As a developer, this means that I can focus on the code and the product I'm working on, knowing that others are doing a first-class job of making sure that the builds are running smoothly and that I'm getting great feedback from the testers. We keep our process light and effective, as we want to produce great software more than we want to produce great audit trails. Tell us a bit about the products you are currently working on. You mean HyperBac? First let me explain a bit about what HyperBac is. At heart it's a compression and encryption technology, but with a few added features that open up a wealth of really exciting possibilities. Right now we have the HyperBac technology in just three products: SQL HyperBac, SQL Virtual Restore and SQL Storage Compress, but we're only starting to develop what it can do. My personal favourite is SQL Virtual Restore; for example, I love the way you can use it to run independent test databases that are all backed by a single compressed backup. I don't think the market yet realises the kind of things you do once you are using these products. On the other hand, the benefits of SQL Storage Compress are straightforward: run your databases but use only 20% of the disk space. Databases are getting larger and larger, and, as they do, so does your ROI. What's a typical day for you? My days are pretty varied. We have our daily team stand-up meeting and then sometimes I will work alone on a current issue, or I'll be pair programming with one of my colleagues. From time to time we give half a day up to future planning with the team, when we look at the long and short term aims for the product and working out the development priorities. I also get to go to conferences and events, which is unusual for a development role and gives me the chance to meet and talk to our customers directly. Have you noticed anything different about developing tools for DBAs rather than other IT kinds of user? It seems to me that DBAs are quite independent minded; they know exactly what the problem they are facing is, and often have a solution in mind before they begin to look for what's on the market. This means that they're likely to cherry-pick tools from a range of vendors, picking the ones that are the best fit for them and that disrupt their environments the least. When I've met with DBAs, I've often been very impressed at their ability to summarise their set up, the issues, the obstacles they face when implementing a tool and their plans for their environment. It's easier to develop products for this audience as they give such a detailed overview of their needs, and I feel I understand their problems.

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Thomas was voted, by his peers,  the most Innovational person in Oracle Direct EMEA of Q1, the first quarter of this fiscal! Thomas, a Business Development Consultant at Oracle Direct’s Applications Team, taught himself how to use and leverage the power of social engagement consistent with Oracle’s Social Media Policy.  From these learning's he provided both his and other applications teams in Dublin with huge amounts of training and has presented his findings to the teams on more than one occasion. It is important to recognise that this isn't just a great idea....it actually works! The results speak for themselves. Thomas is engaging with customers and prospects via their preferred channel of communication and creating a strong personal social brand. We congratulate Thomas for his efforts of raising Social Media to the next level within Business Development Group. He put a lot of work into Social Selling, as one of the first within the BDG and set the example for a new innovative approach on how to sell anno 2013. He deserves to be recognized for this. His contribution to social media has been a great inspiration for all Business Development Consultants or Business Relationship Consultants. He knows what he talks about and has great conversion rates out of his social media campaigns. And he doesn't mind sharing his knowledge with everybody. Great effort in searching for new ways of communication and social selling. Thomas has shown great initiative towards leveraging the social media and networks (twitter, linkedin) to find new business opportunities in a previously way. He has shown great out-of-the-box thinking while addressing new companies and prospects and has shared those experiences and ideas to help his colleagues use the same approach. This included a presentation, informational emails and a general helpful attitude from him. He also shared his success stories from his innovational approach.  Thomas is showing initiative with an innovative and fresh character, truly helping people to try something new  with a focus on selling across channels and working for the CRM team which is focused on selling social. We think the way Thomas positions social, by using social is innovative and inspirational. What better way to tell your clients do social, by engaging with them on a social platform? Going always the extra mile, we believe, that Thomas Brits, is an innovator from the day he walked into Oracle Direct. The way Thomas operates on the work floor by introducing new ideas to find the best opportunities as possible shows he runs the extra mile for coming up with new ideas around how to engage with customers more efficiently for instance via Social Media. Thomas also organises power hours/days for the team.

  • A .NET Developers day with the iPad.

    - by mbcrump
    The Apple iPad is currently getting a lot of buzz because of the app store, the book store and of course iTunes. I had the chance to play with one and this is what I have learned about the device. Let’s get this out of the way first, the iPad is awesome. It is the device for media consumption and casual web browsing. But how does it measure up to those of us with .NET on our brains all days. Let’s find out… Main Screen – you can customize everything on this page. I guess I should replace that image with a C# or VS logo. Its pretty standard stuff if you have an iPhone.   Programming Books If you have a subscription to Safari Books Online, then you are in luck, its very easy to read the books on the iPad. Just fire up Safari web browser and goto the Safari Books Online. The biggest benefit that I can see with the iPad is the ability to read books wherever and not have to worry about purchasing books that I already have the .PDF for. Below is a sample from Code Complete 2nd Edition. Below is a PDF of the ECMA-334 C# Language Specification. As you can see its very readable and you should have no problem reading actual code.   Example of Code shown below: It is however easier to read the PDF and store them with a 3rd party PDF reader. I have seen several for .99 cents or less. You can however switch the screen to vertical to get more viewing space as shown below: I was disappointed with the iBooks application. I could not find a single .NET programming book anywhere. I was able to download the excellent sci-fi book “A memory of Wind” for free though. If I just overlooked them, then please email me with the names and titles. I couldn’t even find a technology category in the categories list. Web Surfing – Technical Sites Below is an example of my site in Safari. The code is very readable and the experience was identical to viewing it in Firefox. I tried multiple programming site and the pages looked great except those that used flash and of course it did not display on those pages.   News Apps - Technical Content The standard NY Times and USA Today looked great, but the Technical Content was lacking. It would probably be better to use Google Reader for online technical news.     YouTube Videos – Technical Content  Since its YouTube, we already know that a lot of technical content exist and it plays great on the iPad. I watched several programming videos and could clearly see the code being written. Taking Technical Notes The iPad comes with a great notepad for taking notes. I found that it was easy to take notes regarding projects that I am currently working on.   Calendar The calendar that ships with the iPad is great for organizing. You can setup exchange server or manually enter the information. Pretty standard stuff.    Random Applications that I like: TweetDeck.   and Adobe Ideas. Adobe Ideas is kinda like SketchFlow except you use your finger to mock up the sketches.  Don’t forget that the iPad is great for any type of podcasting. That pretty much sums it up, I would definitely recommend this device as it will only get better. I believe the iOS4 comes out on the 24th and the iPad will only get more and more apps. You could save a few bucks by waiting for the 2nd generation, but that’s a call that only you can make.

  • In a Rails unit test, how can I get a User fixture to load its associated Profile?

    - by MikeJ
    In the documentation concerning Fixtures (http://api.rubyonrails.org/classes/Fixtures.html) they provide the following example of using label references for associations: ### in pirates.yml reginald: name: Reginald the Pirate monkey: george ### in monkeys.yml george: name: George the Monkey pirate: reginald So following their lead, I have a User model that has_one :profile, a Profile model that belongs_to :user, and tried to set up fixtures per their example: ### in users.yml reginald: id: 1 login: reginald ### in profiles.yml reginalds_profile: id: 1 name: Reginald the Pirate user: reginald (Note: since my association is one-way, the User fixture doesn't have a "profile: reginalds_profile" association--putting it in causes an error because the SQL table has no profile_id attribute.) The problem is, in my unit tests everything seems to load correctly, but users(:reginald).profile is always nil. What am I missing?

  • Finding specific pixel colors of a BitmapImage

    - by Andrew Shepherd
    I have a WPF BitmapImage which I loaded from a .JPG file, as follows: this.m_image1.Source = new BitmapImage(new Uri(path)); I want to query as to what the colour is at specific points. For example, what is the RGB value at pixel (65,32)? How do I go about this? I was taking this approach: ImageSource ims = m_image1.Source; BitmapImage bitmapImage = (BitmapImage)ims; int height = bitmapImage.PixelHeight; int width = bitmapImage.PixelWidth; int nStride = (bitmapImage.PixelWidth * bitmapImage.Format.BitsPerPixel + 7) / 8; byte[] pixelByteArray = new byte[bitmapImage.PixelHeight * nStride]; bitmapImage.CopyPixels(pixelByteArray, nStride, 0); Though I will confess there's a bit of monkey-see, monkey do going on with this code. Anyway, is there a straightforward way to process this array of bytes to convert to RGB values?

  • How to recursively serialize an object using reflection ?

    - by Tony
    I want to navigate to the N-th level of an object, and serialize it's properties in String format. For Example: class Animal { public String name; public int weight; public Animal friend; public Set<Animal> children = new HashSet<Animal>() ; } should be serialized like this: {name:"Monkey", weight:200, friend:{name:"Monkey Friend",weight:300 ,children:{...if has children}}, children:{name:"MonkeyChild1",weight:100,children:{... recursively nested}} } And you may probably notice that it is similar to serializing an object to json. I know there're many libs can do this, can you give me some instructive ideas on how to write this?

  • How to find the maximum value for each key in a List of Dictionaries using LINQ?

    - by Argos
    I have a List of Dictionaries that have keys of type string and values that are ints. Many of the dictionaries have the same keys in them but not all of them. So my question is: using LINQ how would I find the maximum value associated with each distinct key across all of the dictionaries? So for example given the following input: var data = new List<Dictionary<string, int>> { new Dictionary<string, int> {{"alpha", 4}, {"gorilla", 2}, {"gamma", 3}}, new Dictionary<string, int> {{"alpha", 1}, {"beta", 3}, {"gamma", 1}}, new Dictionary<string, int> {{"monkey", 2}, {"beta", 2}, {"gamma", 2}}, }; I would like some kind of collection that contains: {"alpha", 4}, {"gorilla", 2}, {"gamma", 3}, {"beta", 3}, {"monkey", 2} (I'm currently looping through the list and keeping track of things myself, really just wondering if there is a nicer LINQ-esque way of doing it) EDIT: I also don't know what the string keys are in advance

  • How do polymorphic inline caches work with mutable types?

    - by kingkilr
    A polymorphic inline cache works by caching the actual method by the type of the object, in order to avoid the expensive lookup procedures (usually a hashtable lookup). How does one handle the type comparison if the type objects are mutable (i.e. the method might be monkey patched into something different at run time). The one idea I've come up with would be a "class counter" that gets incremented each time a method is adjusted, however this seems like it would be exceptionally expensive in a heavily monkey patched environ since it would kill all the PICs for that class, even if the methods for them weren't altered. I'm sure there must be a good solution to this, as this issue is directly applicable to Javascript and AFAIK all 3 of the big JS VMs have PICs (wow acronym ahoy).

  • Best way to search for a saturation value in a sorted list

    - by AB Kolan
    A question from Math Battle. This particular question was also asked to me in one of my job interviews. " A monkey has two coconuts. It is fooling around by throwing coconut down from the balconies of M-storey building. The monkey wants to know the lowest floor when coconut is broken. What is the minimal number of attempts needed to establish that fact? " Conditions: if a coconut is broken, you cannot reuse the same. You are left with only with the other coconut Possible approaches/strategies I can think of are Binary break ups & once you find the floor on which the coconut breaks use upcounting from the last found Binary break up lower index. Window/Slices of smaller sets of floors & use binary break up within the Window/Slice (but on the down side this would require a Slicing algorithm of it's own.) Wondering if there are any other way to do this.

  • Why use threading data race will occur, but will not use gevent

    - by onlytiancai
    My test code is as follows, using threading, count is not 5,000,000 , so there has been data race, but using gevent, count is 5,000,000, there was no data race .

  • Developer’s Life – Every Developer is a Spiderman

    - by Pinal Dave
    I have to admit, Spiderman is my favorite superhero.  The most recent movie recently was released in theaters, so it has been at the front of my mind for some time. Spiderman was my favorite superhero even before the latest movie came out, but of course I took my whole family to see the movie as soon as I could!  Every one of us loved it, including my daughter.  We all left the movie thinking how great it would be to be Spiderman.  So, with that in mind, I started thinking about how we are like Spiderman in our everyday lives, especially developers. Let me list some of the reasons why I think every developer is a Spiderman. We have special powers, just like a superhero.  There is a reason that when there are problems or emergencies, we get called in, just like a superhero!  Our powers might not be the ability to swing through skyscrapers on a web, our powers are our debugging abilities, but there are still similarities! Spiderman never gives up.  He might not be the strongest superhero, and the ability to shoot web from your wrists is a pretty cool power, it’s not as impressive as being able to fly, or be invisible, or turn into a hulking green monster.  Developers are also human.  We have cool abilities, but our true strength lies in our willingness to work hard, find solutions, and go above and beyond to solve problems. Spiderman and developers have “spidey sense.”  This is sort of a joke in the comics and movies as well – that Spiderman can just tell when something is about to go wrong, or when a villain is just around the corner.  Developers also have a spidey sense about when a server is about to crash (usually at midnight on a Saturday). Spiderman makes a great superhero because he doesn’t look like one.  Clark Kent is probably fooling no one, hiding his superhero persona behind glasses.  But Peter Parker actually does blend in.  Great developers also blend in.  When they do their job right, no one knows they were there at all. “With great power comes great responsibility.”  There is a joke about developers (sometimes we even tell the jokes) about how if they are unhappy, the server or databases might mysteriously develop problems.  The truth is, very few developers would do something to harm a company’s computer system – they take their job very seriously.  It is a big responsibility. These are just a few of the reasons why I love Spiderman, why I love being a developer, and why I think developers are the greatest.  Let me know other reasons you love Spiderman and developers, or if you can shoot webs from your wrists – I might have a job for you.

  • My VS 2010 and ASP.NET 4 Talks Online

    - by ScottGu
    The past 7 years I’ve done an annual all day event in Arizona – organized by the most excellent Scott Cate (who always does a phenomenal job organizing the event and making it a great one). Earlier this month I visited and presented 4+ hours of content covering VS 2010, ASP.NET 4 and ASP.NET MVC 2.  NextSlide.com – a great .NET shop local to Arizona who has a great product for sharing presentations – volunteered to record the talks and publish them for free using their online presentation tool.  The recordings they did turned out really, really great – and their online player (which combines slides + camera of me + demos in one experience) is awesome.  Below you can watch the first two segments of my event – which cover VS 2010 and ASP.NET 4 – for free online using the NextSlide.com player experience.  I’ll post a link to my ASP.NET MVC 2 segment a little later in a separate blog post.  If you’ve never seen my present these talks before and are interested in the content then I’d recommend checking them out – as these recordings do a really good job capturing them. Part 1 - VS 2010 This is a 49 minute segment that starts the event and covers a bunch of the new improvements in VS 2010.  You can launch the presentation directly here or watch it inline below.  You can download powerpoint versions of my slides here. Part 2- ASP.NET 4 This 61 minute segment comes next and drills into some of the framework improvements with ASP.NET 4.  It also goes further on some of the web specific tooling improvements in VS 2010 – and towards the end demonstrates some of the great new end-to-end web deployment features provided with VS 2010 (which work for both ASP.NET Web Forms and ASP.NET MVC applications). You can launch the presentation directly here or watch it inline below: Learning More about VS 2010 and ASP.NET 4 I’ve been working on a series of blog post about VS 2010 and .NET 4.  Many of the features I covered in my two talks above are described in more detail in posts within the series.  You can read all of them here. I’ll be continuing adding to the series via my blog, so stay tuned for more in-depth posts about a bunch more new features. Hope this helps, Scott P.S. People often ask whether they can re-use the slides+demos I use in my talks for talks of their own.  The answer to this is always absolutely! No need to ask permission.  Feel free to re-use all of my slides for talks of your own. P.P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links.

  • New Themes New Benefits (WinForms)

    We believe that working hard on something can be great fun at the end when everything is done and the seeds have resulted in the sweetest fruits. This is the case with the new Theming Mechanism and the new Visual Style Builder which we introduced as of Q1 2010.   I am not going to dive into any details on the new concepts behind all this stuff, but will simply focus on the numbers: both in terms of loading speed and memory usage. As you may already know, the new approach we use to style our controls uses the so called Style Repository which stores style settings that can be reused throughout the whole theme. As a result, we have estimated that the size of our themes has been significantly reduced. For instance, the size of all XML files of the Desert theme sums up to 1.83 MB. The case with the new version of the Desert theme is drastically different. Despite the fact that the new theme consists of more XML files compared to the old, its size is only 707 KB!   Furthermore, we have performed a simple performance test since the common sense tells us that such a great improvement in terms of memory footprint should be followed by a great improvement in terms of speed. We have estimated that loading and applying the new Desert theme to a form containing all RadControls for WinForms takes roughly 30% less time compared to the same operation with the old version of the Desert theme. The following screenshots briefly demonstrate the scenario which we used to estimate the loading time difference between the old and the new Desert theme:     Here, the old Desert theme is applied to all controls on the Form which takes almost 1,3 seconds.     Applying the new Desert theme (based on the new Theming Mechanism) takes about 0,78 seconds.   On top of all these great improvements, we can add the fact that the new Visual Style Builder significantly reduces the time needed to style a control by entirely changing the approach compared to the old version of this tool. You can be sure that we have already prepared some great new stuff for Q1 2010 SP1 that will simplify things further so that designing themes with the new VSB will become more fun than ever!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

This is the case with the new Theming Mechanism and the new Visual Style Builder which we introduced as of Q1 2010.   I am not going to dive into any details on the new concepts behind all this stuff, but will simply focus on the numbers: both in terms of loading speed and memory usage. As you may already know, the new approach we use to style our controls uses the so called Style Repository which stores style settings that can be reused throughout the whole theme. As a result, we have estimated that the size of our themes has been significantly reduced. For instance, the size of all XML files of the Desert theme sums up to 1.83 MB. The case with the new version of the Desert theme is drastically different. Despite the fact that the new theme consists of more XML files compared to the old, its size is only 707 KB!   Furthermore, we have performed a simple performance test since the common sense tells us that such a great improvement in terms of memory footprint should be followed by a great improvement in terms of speed. We have estimated that loading and applying the new Desert theme to a form containing all RadControls for WinForms takes roughly 30% less time compared to the same operation with the old version of the Desert theme. The following screenshots briefly demonstrate the scenario which we used to estimate the loading time difference between the old and the new Desert theme:     Here, the old Desert theme is applied to all controls on the Form which takes almost 1,3 seconds.     Applying the new Desert theme (based on the new Theming Mechanism) takes about 0,78 seconds.   On top of all these great improvements, we can add the fact that the new Visual Style Builder significantly reduces the time needed to style a control by entirely changing the approach compared to the old version of this tool. You can be sure that we have already prepared some great new stuff for Q1 2010 SP1 that will simplify things further so that designing themes with the new VSB will become more fun than ever!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Nokia vs. The World

    - by Michael B. McLaughlin
    I’m looking forward to the launch of the Nokia Lumia 920. Why? Well, it stacks up better than the competition for one thing. Then there’s also that security problem that certain other phones have. Mostly, though, it’s because I love my Lumia 900 and the 920, with Windows Phone 8, will be even better. Before I got my Lumia 900, I just took it as given that smart phone cameras couldn’t be good. The Lumia taught me that smart phone cameras can be good if the manufacturer treats them as an important component worth spending time and money on (rather than some thing that consumers expect such that they’d better throw one in). I’m extremely pleased with the quality of pictures that my Lumia 900 gives me as well as the range of settings it provides (you can delve in to tell it a film speed, an f-stop, and a whole range of other settings). And the image stabilization features in the Lumia 920 deliver far better results than the others. Nokia has had great maps for a long time and they continue to improve. Even better, they made a deal that puts many of their excellent maps into Windows Phone 8 itself. There are still Nokia-exclusive features such as Nokia City Lens, of course. But by giving the core OS a great set of fundamental map data and technologies, they help ensure that customers know that buying a Windows Phone 8 will give them a great map experience no matter who made the phone. I’ll be getting a 920, myself, but the HTC and Samsung devices that have been announced have some compelling features, too, and it’s great to know that people who buy one of these won’t need to worry about where their maps might lead them. I’m looking forward to the NFC capabilities and Qi wireless charging my Lumia 920 will have. With the availability of DirectX and C++ programming on Windows Phone 8, I’m also excited about all the great games that will be added to the Windows Phone environment. I love my Xbox Phone. I love my Office phone. I love my Facebook phone. I love my GPS phone. I love my camera phone. I love my SkyDrive phone. In short, I love my Windows Phone!

  • SQLAuthority News – A Quick Note on @Pluralsight Video – Call Me Maybe Developer Way

    - by pinaldave
    I write a lot about how important learning and training is.  Any of my readers will know that I think the key to success is staying current with your education and taking very opportunity to increase your “tool kit” of skills.  I hope that I have not made the impression that it is all in the employees hands to make sure they are happy and satisfied at their jobs. I also firmly believe that a good boss will make good employees.  A boss who is good at communicating,  and leading, who knows how to nip problem in the bud and allocate resources wisely will have a well-oiled machine.  This means happy employees and a great work environment. It is important to have a healthy work environment because you will not succeed without one.  Successful business will always have the type of environment that fosters creativity and has efficient employees.  A healthy environment doesn’t force employees to produce results, but allows them to progress and create the results themselves. The result of a healthy work environment is that employees will enjoy their work and then work harder.  This can bring the company more revenue, and hopefully the employees will see the result of their hard work in bonuses and raises.  However, money is important but it is certainly secondary – the important part is the dedication of the employees to their work and to their company.  This is the true key to success. Any employee who recognizes this description as their working environment should consider themselves fortunate.  They are allowed to grow and do better, and employees being treated fairly can be a rarity in this world.  One company that I believe adheres to this principle is Pluralsight – as evidenced by this fun video. I have blogged about it earlier. (check out my cameo at 0:37). It was great fun to work with the employees at Pluralsight while making this video.  They are a great bunch and clearly have a great work environment – we wouldn’t have had this much fun if not!  I have to tell you a little bit about making this video.  My wife shot it with her mobile phone, which was certainly a different but exciting experience!  It was hard to get the look of the video right, since I was trying to portray a body builder – this was a little outside of my own personal experience.  I have what I like to call a “healthy” body type, so trying to look extremely fit like some of the other “actors” in this video was a challenge – but I do hope that you all think I succeeded.  All in all, it was great fun to participate in this video and I hope to see my friends at Pluralsight again soon.

  • SQL SERVER – Free eBook Download – EPUB, MOBI, PDF Format

    - by pinaldave
    Microsoft has released recently free eBooks on various Microsoft Technology. The best part is that all these books are available in ePub, Mobi and PDF. You can download them to your local machine or eBook reader and read them. This is a great start as many important subjects are now covered and converted into an eBook. I personally read through a few of the books and found they are very comprehensive and and detailed. The goal is not to cover complete technology in a single book but rather pick a single topic and discuss it in detail. The source of the book is white paper, Technet wiki as well book online and it is clearly listed right bellow the book title. Following are the books available for SQL Server Technology and I encourage all of you to have a look at them as they are great resources. Master Data Services Capacity Guidelines Microsoft SQL Server AlwaysOn Solutions Guide for High Availability and Disaster Recovery Microsoft SQL Server Analysis Services Multidimensional Performance and Operations Guide QuickStart: Learn DAX Basics in 30 Minutes SQL Server 2012 Transact-SQL DML Reference You can download above eBooks from here. This is indeed a great attempt as each book talks about the a single subject in depth keeping author focus on the single and simple subject. I have previously written two books by focusing on the same subject and I had great pleasure writing it as well. Writing on focus subjects gives complete freedom to author to explore the a single subject without having burden to cover everything which is associated with that technology at large. Just like eBooks mentioned earlier my SQL Server Wait Stats was inspired from my article series on SQL Wait Stats. The latest book SQL Server Interview Question and Answers was derived from my article series on SQL Interview Q and A. Writing book is an absolutely different concept than writing blog posts. When I was converting my blog posts to books, I ended up writing 50% new material and end up removing many repetitive content which shows up in blog series. It was indeed fun to focused book at the same time it was a great learning experience as an individual.

  • JUDCon 2013 Trip Report

    - by reza_rahman
    JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

  • OpenWorld in Small Bites

    - by Kathryn Perry
    Fifty thousand attendees -- that's bigger than the cities some of us live in. Monday morning it took 20 minutes to get from Hall D in Moscone North to a conference room in Moscone South -- the crowds were crushing! A great start to a great week! Larry is as big a name as ever on the program schedule and on the Moscone stage. People were packed in Hall D and clustered around every big screen TV. He stayed on script as he laid out Oracle's SaaS, PaaS, and IaaS strategies. Every seat in Chris Leone's Fusion Apps Cloud Overview was filled on Monday morning. Oracle employees who wanted to get in were turned away. And the same thing happened in the repeat session on Wednesday. Our newest suite of apps is hot! Speaking of hot, the weather was made to order. Then it turned very San Francisco-like on Wednesday afternoon. Downright cold for those who trusted SF temps to hold in the 80's. Who did you follow on Twitter during the conference? So many voices, opinions, and convos! Great combo of social media and sharp minds. Be sure to follow @larryellison, @stevenrmiranda, and @Oracle for updates and MyPOVs. Keywords for the Apps customers at the conference were cloud, mobile, and social. Every day, every session, every speaker. Wednesday afternoon, 4 pm at the Four Seasons hotel. A large roomful of analysts and influencers firing questions at a panel of eight Fusion customers. Steve Miranda moderating. Good energy and a great exchange of information and confidence. Word on the street is that OpenWorld has outgrown San Francisco -- but moving it seems unthinkable. The city isn't just a backdrop for an industry conference - it's a headliner right up there with Larry Ellison and Pearl Jam. As you can imagine, electrical outlets were in high demand at every venue. The most popular hotels and bars near Moscone designed their interiors around accessible electrical power strips. People are plenty willing to buy a drink while they grab a charge. Wednesday afternoon, 4 pm at the Four Seasons hotel. A large roomful of analysts and influencers firing questions at a panel of eight Fusion customers. Steve Miranda moderating. Good energy and a great exchange of information and confidence. Treasure Island in the dark. Eddy Vedder has an amazing voice! And Kings of Leon over delivered on people's expectations. It was cold. It was windy. It was very fun. One analyst said it's the best customer appreciation party in the industry.

  • HTML: Creating tool in HTML which enables to mark on an image

    - by A.Amidi
    I am creating an online survey-monkey for conducting a research. Participants are asked to mark the preferred places for building the parking on the map (image). In other words, participants should be able to mark on the image (map) wherever they want and subsequently I could have an access to the saved locations after survey. I am writing to know how I can provide tools for participants to draw or mark on the map by using HTML codes.

  • What's New in 5.6 RC and more from MySQL Connect conference

    - by Rob Young
    Keeping with the tradition of great MySQL Community events, the first annual MySQL Connect conference is now in the books.  It was great to see so many familiar faces in the crowd and at the podium sharing their ideas and thoughts on the evolution of MySQL under Oracle. The headliner of the conference was Tomas' keynote announcement of the fully featured and fully enabled MySQL 5.6 Release Candidate.  This new article on the MySQL DevZone summarizes all of the great new features ready for Community adoption, all MySQL Engineering blogs and where and how to download all of the bits. As always, early adoption and feedback on the 5.6 RC is appreciated and the sooner we get your feedback the sooner we release the "ready for production" sanctioned GA product.    Also available now, Cluster 7.3 provides support for Foreign Keys, node.js NoSQL access to underlying data and a new Auto Installer that helps you quickly and easily get up and running with Cluster 7.2 and 7.3.  The 7.3 downloads are provided in the first 7.3 Development Milestone Release (under "Development Releases" tab) and via the MySQL Labs. Oracle also announced key new additions to MySQL Enterprise Edition: New policy-based compliance Auditing. MySQL Enterprise Edition Audit adds policy-based auditing compliance to existing MySQL applications without the need to change any code.  This new plugin is available for MySQL 5.5.28 and higher; existing MySQL Enterprise Edition customers can download the upgrade from the My Oracle Support portal and all can download for evaluation from Oracle's Software Delivery Cloud. New MySQL Enterprise High Available additions provide even more options for ensuring MySQL applications remain available and running a their peak: Oracle Linux + DRBD Oracle Solaris Clustering for MySQL All in all, the first MySQL Connect conference was a great success and with refinements planned in response to attendee, sponsor and speaker feedback we expect it to grow and improve going forward. As always, thanks for your continued support of MySQL!

  • Schedule for my session at MIX10

    - by Laurent Bugnion
    Microsoft has published the schedule for the MIX10 sessions. I have a sweet spot, and I dearly hope that it stays this way (Last year I had a great spot, but it was changed last minute and then I had a much better one, “competing” against Vertigo and their Playboy app… yeah try to explain to a bunch of geeks that MVVM is better than Playboy… good luck with that ;) Anyway, this year my sweet spot is on the very first day of the conference (there are workshops on Sunday, but this qualifies as pre-conference), Monday after the keynote which should get everyone pumped and excited. Schedule and location I would be really happy to meet y’all at Understanding the Model-View-ViewModel Pattern in Lagoon F on Monday at 2:00 PM http://live.visitmix.com/MIX10/Sessions/EX14 See you in Vegas (or in video…) Everything I saw so far hints that this should be a very, very exciting edition of MIX, maybe the most electrifying ever. The great news is that everything will be available even if you cannot make it: The keynotes are typically streamed live, and if you remember last year’s experience at PDC, it is a really good alternative. Built with Silverlight, the feed uses smooth streaming (adjusting the quality according to your bandwidth automatically), possibility to pause and rewind if you miss something, and a great picture quality. As for the sessions, the message at MIX is that the videos will be available online approximately 24 hours after the session is being held. This is a great feat! So, see you in Vegas (or in video)! Cheers, Laurent

  • Microsoft turning into a toothless tiger?

    <b>Technology & Life Integrationt:</b> "Many moons ago ( and I am not talking about those drunken moons at passing cars :), while the IT jungle was still fresh and green. There was a big blue king of the jungle. This top monkey position was usurped by an up and coming tiger that, while the tigers name seemed small and soft, it wasn't afraid to show its teeth."
