• What guidelines are best suited for leveraging automatic deployments?

  - by Scott

  We are hoping to leverage a static code analysis tool (Sonar) as part of our continuous integration server, and are hoping to determine some useful guidelines to serve as a base for allowing the deployment to continue. What conditions should we make mandatory before allowing a build to proceed to the next set of testing? The obvious answers include that it compiles and the unit tests are successful. But what are some other things we should require before allowing a build to not be rolled back?

• C# 5: At last, async without the pain

  - by Alex.Davies

  For me, the best feature in Visual Studio 11 is the async and await keywords that come with C# 5. I am a big fan of asynchronous programming: it frees up resources, in particular the thread that a piece of code needs to run in. That lets that thread run something else, while waiting for your long-running operation to complete. That's really important if that thread is the UI thread, or if it's holding a lock because it accesses some data structure. Before C# 5, I think I was about the only person in the world who really cared about asynchronous programming. The trouble was that you had to go to extreme lengths to make code asynchronous. I would forever be writing methods that, instead of returning a value, accepted an extra argument that is a "continuation". Then, when calling the method, I'd have to pass a lambda in to it, which contained all the stuff that needed to happen after the method finished. Here is a real snippet of code that is in .NET Demon: m_BuildControl.FilterEnabledForBuilding(     projects,     enabledProjects = m_OutOfDateProjectFinder.FilterNeedsBuilding(         enabledProjects,         newDirtyProjects =         {             // Mark any currently broken projects as dirty             newDirtyProjects.UnionWith(m_BrokenProjects);             // Copy what we found into the set of dirty things             m_DirtyProjects = newDirtyProjects;             RunSomeBuilds();         })); It's just obtuse. Who puts a lambda inside a lambda like that? Well, me obviously. But surely enabledProjects should just be the return value of FilterEnabledForBuilding? And newDirtyProjects should just be the return value of FilterNeedsBuilding? C# 5 async/await lets you write asynchronous code without it looking so stupid. Here's what I plan to change that code to, once we upgrade to VS 11: var enabledProjects = await m_BuildControl.FilterEnabledForBuilding(projects); var newDirtyProjects = await m_OutOfDateProjectFinder.FilterNeedsBuilding(enabledProjects); // Mark any currently broken projects as dirty newDirtyProjects.UnionWith(m_BrokenProjects); // Copy what we found into the set of dirty things m_DirtyProjects = newDirtyProjects; RunSomeBuilds(); Much easier to read! But how is this the same code? If we were on the UI thread, doesn't the UI thread have to block while FilterEnabledForBuilding runs? No, it doesn't, and that's the magic of the await keyword! It cuts your method up into its constituent pieces, much like I did manually with lambdas before. When you run it, only the piece up to the first await actually runs. The rest is passed to FilterEnabledForBuilding as a continuation, which will get called back whenever that method is finished. In the meantime, our thread returns, and can go back to making the UI responsive, or whatever else threads do in their spare time. This is actually a massive simplification, and if you're interested in all the gory details, and speed hacks that the await keyword actually does for you, I recommend Jon Skeet's blog posts about it.

• Database Snapshot in Sql Server 2005

  A database snapshot is a read-only, static view of a database (called the source database). Each database snapshot is transactionally consistent with the source database at the moment of the snapshot's creation. When you create a database snapshot, the source database will typically have open transactions. Before the snapshot becomes available, the open transactions are rolled back to make the database snapshot transactionally consistent.

• Focusing on Mobile @ Oracle OpenWorld

  - by Carlos Chang

  Plenty of exciting trends in the industry today: Cloud, Big Data, Mobile, etc. The first two are amazing of course, but for me, it's mobile, mobile and... MOBILE.   Why? Think back to the mozilla browser (Marc Andreessen's mozilla, not today's mozilla.org), Netscape and the nascent beginnings of the World Wide Web. Amazing times. Companies were just starting to set up their home pages, basic HTML, hyperlinks, images, ooooh, aaaah.  Yahoo! was *the* search engine back then. :-\   Anywhoo, I would pose that mobile today, we are in a similar junction. Sure, there's millions of apps on Apple's App Store and Google Play, but within the enterprise, it's just getting started. I'm talking about going beyond the simple, tactical apps such as calendaring, contacts or directory service lookup. And while mobile first a common mantra, I'm referring to mobile plus which includes and looks upon the whole enterprise holistically and adds new parameters, such as your GPS location, perhaps even your vital signs. (Apple's health kit?)  Everything is going mobile. Everything connected. But with the enterprise - scalability, security, integration, app management, user management, etc. Amazing times ahead. Ok, got that off my mind. Oracle OpenWorld 2014 - Going Mobile!  If you're coming to the big dance, I've highlighted some key mobile sessions below. And if you see me around, and there's a bar within reach, high five me for a beer. I mean, if you read this far, and didn't already jump to the list below, I think you deserve one.   Cheers!  Monday, 9/29/14 at 10:15 AM - General Session: Time for You to Rethink Mobile?

• Loading another domain's content in a modal iframe - acceptable?

  - by user568458

  Is it okay to load another page in an iframe in a modal pop-up window - in terms of legal and ethical standards around displaying 3rd party content? I remember a few years ago there was controversy and a debate about whether it was okay to load another domain's page content on your domain in a full-width iframe, with your site providing a masthead with controls for favouriting, linking etc (e.g. like StumbleUpon). I seem to recall that the consensus was, that it was okay so long as you were clearly in no way claiming ownership of the 3rd party content or attempting to modify the content and so long as there was a 'go to site' button or equivalent; and that sites could ask you to exclude them, but generally speaking, it's an acceptable practice. How acceptable would it be considered to be to load another site's page within a modal (lightbox-like) popup box (following all the above principles: clear attribution and a prominent button that kills the iframe and gives them the 3rd party original)? My expectation would be that it would follow the same principles, and be acceptable so long as these conditions were met. Note that I'm asking about the likely legitimate responses of the 3rd party sites and possible legal position, not about usability or UX. I'm aware that this should never ever ever ever ever be the standard way external links are loaded, and that 99% of the time linking to external content like this would be terrible for usability. My specific use case is one of those 1% of cases where loading a separate page in this tab actually wouldn't be the expected behaviour of a link: an interactive data visualisation tool that also acts as a 'browser' of external content (science papers underlying the data it navigates). All other links within the interactive will change something while staying on the same page. If the user clicked one of these external links by mistake (as people often do, even when they are clearly, noisily labelled) and then had to back-button back, they would lose their fine-grained position in the interactive tool (jquery bbq hashchanges being not appropriate for all elements of the tool). New window/tab will simply open the target page on the 3rd party domain. Opening a new window/tab would also be an alternative option (and has its own disadvantages) - my question is, whether this is an alternative that could be considered (in terms of acceptable practice around intellectual property etc), irrespective of which option is best for UX: which is something we'll decide the proper way, based on actual UX testing.

• Is there a way to manage my Grub menu options from with the GUI/desktop?

  - by Neil Trodden

  With each kernel update, a new entry is placed in Grub to provide a way to boot that specific kernel version. I have about 5 at the moment and, to be honest, once I have confirmed I can boot into the new kernel version, I never go back to a previous version. I'd like to manage the items in this list from the desktop rather than edit the file, is there a way to do this using the GUI from within Ubuntu itself?

• How to make Unity's Dash save the results filtering?

  The dash can remember the settings for filtered results for the entire session, but not beyond that. Once the profile is logged out and back in the results would reset to their original settings; displaying all the results without filtering. How can I make the results filtering more permanent? IE: How to make the photo lens for instance always show photos from "This Computer" and not from Picasa or Facebook across sessions and not just temporarily?

• What languages are the kids of today actually programming in? Does anyone have real data?

  - by Gaz Davidson

  Back in the 80s colleges were teaching Pascal because it is easy to learn, while myself and many others like me were learning BASIC because it was not only easy to learn but accessible and also fashionable (for an extremely liberal definition of fashion) It has just occurred to me that empirical data on the actual programming languages kids are choosing to use should be a good indicator of which language would be the ideal first choice for educators. Please note that this question is not "what do you think is a good programming language for kids?"

• Expanding Influence and Community

  - by Johnm

  When I was just nine years of age my father introduced me to the computer. It was a Radio Shack TRS-80 Color Computer (aka: CoCo). He shared with me the nuances of writing BASIC and it wasn't long before I was in the back seat of the school bus scribbling, on a pad of paper, the code I would later type. My father demonstrated that while my friends were playing their Atari 2600 consoles, I had the unique opportunity to create my own games on the Coco. One of which provided a great friend of mine hours and hours of hilarity and entertainment. It wasn't long before my father was inviting me to tag along as he drove to the local high school where a gathering of fellow Coco enthusiasts assembled. In these meetings all in attendance would chat about their latest challenges and solutions. They would swap the labors of their sleepless nights eagerly gazing into their green and black screens. Friendships were built and business partners were developed. While these experiences at the time in my pre-teen mind were chalked up to simply sharing time with my father, it had a tremendous impact on me later in life. This past weekend I attended the Louisville SQL Saturday (#45). It was great to see that there were some who brought along their children. It is encouraging to see fresh faces in the crowd at our  monthly IndyPASS meetings. Each time I see the youthful eyes peering from the audience while the finer details of SQL Server is presented, I cannot help but to be transported back to the experiences that I enjoyed in those Coco days. It is exciting to think of how these experiences are impacting their lives and stimulating their minds. Some of these children have actually approached me asking questions about what was presented or simply bragging about their latest discovery in programming. One of the topics that arose in the "Women in Technology" session in Louisville, which was masterfully facilitated by Kathi Kellenberger, was exploring how we could ignite the spark of interest in databases among the youth. It was awesome to hear that there were some that volunteer their time to share their experiences with students. It made me wonder what user groups could achieve if we were to consider expanding our influence and community beyond our immediate peers to include those who are simply enjoying their time with their father or mother.

• Configuring mouse buttons

  I am using a HP NK527AA Wireless mouse with two side buttons. His mouse wheel is half broken: I can scroll but I can't click it. In windows I configured the side buttons as 3rd mouse button but unfortunately the only available drivers are for windows. Ubuntu treats the side-buttons as back\forward buttons and it's really annoying. Is there a way to configure the buttons if though the is no driver?
