• Designing a social network with CQRS, graph databases and relational databases in mind

  - by Siraj Mansour

  I have done quite an amount of research on the topic so far, but i couldn't come up with a conclusion to make up my mind. I am designing a social network and during my research i stumbled upon graph databases, i found neo4j pretty interesting for user relations and traversing through nodes. I also thought of using a relational database such as MS-SQL or MySQL to store entity data only and depending on neo4j for connections between entities. Of course this means more work in my application to store and pull data in and out of 2 different sources. My first question : Is using this approach (graph + relational) a good approach for designing my social network keeping in mind that users on social networks don't have to in synch with real data by split second ? What are the positives and negatives of this approach ? My Second question : I've been doing some reading on CQRS and as i understood it is mostly useful for collaborative environments, and environments where users see a lot of "stale" data. social networks has shared comments, events, etc .. and many users query or update the same data. Could CQRS be a helpful approach ? Would it give any performance/scalability benefits or non-useful complexity ? Is it fairly applicable with my possible choice of (graph + relational) databases approach mentioned in the question above ? My purpose is to know if the approaches i have mentioned above seem good enough for the business context.

• Speaking at DevReach

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Next week, I will be speaking at Devreach on the following topics - Authoring custom WCF services in SharePoint Sahil Malik, Level 400 We live in a different world today! Gone are the times when you built your webparts around postbacks! Welcome silverlight, jquery, bing maps, google maps, and many others! And there are many enhancements in SharePoint 2010 that let you build such applications, the question is which is right for you? In this session Sahil compares WCF REST Services in SharePoint, The client object model, and custom WCF services, and then dives deep into the WCF aspects of SharePoint. All code, very few slides!   Scalability and Performance of SharePoint 2010 Sahil Malik, Level 400 If there is a topic that has more misinformation than anything else, it has to be the scalability and performance aspects of SharePoint. Did you know, SharePoint 2010 has some real world, under the covers improvement that help it perform and scale better? This session involves taking a deep look under the covers into the specific improvements Microsoft has made between SharePoint 2007 and SharePoint 2010 that truly qualifies SharePoint 2010 as an enterprise scalable product. This doesn't mean the product doesn't have limits - but this session is a lot more than just limits written on a powerpoint slide. This presentation is a true under the scenes look at specific improvements!   Devreach is a premier conference, check out their very impressive speaker and sessions line up.

• Slide-decks from recent Adelaide SQL Server UG meetings

  - by Rob Farley

  The UK has been well represented this summer at the Adelaide SQL Server User Group, with presentations from Chris Testa-O’Neill (isn’t that the right link? Maybe try this one) and Martin Cairney. The slides are available here and here. I thought I’d particularly mention Martin’s, and how it’s relevant to this month’s T-SQL Tuesday. Martin spoke about Policy-Based Management and the Enterprise Policy Management Framework – something which is remarkably under-used, and yet which can really impact your ability to look after environments. If you have policies set up, then you can easily test each of your SQL instances to see if they are still satisfying a set of policies as defined. Automation (the topic of this month’s T-SQL Tuesday) should mean that your life is made easier, thereby enabling to you to do more. It shouldn’t remove the human element, but should remove (most of) the human errors. People still need to manage the situation, and work out what needs to be done, etc. We haven’t reached a point where computers can replace people, but they are very good at replace the mundaneness and monotony of our jobs. They’ve made our lives more interesting (although many would rightly argue that they have also made our lives more complex) by letting us focus on the stuff that changes. Martin named his talk Put Your Feet Up, which nicely expresses the fact that managing systems shouldn’t be about running around checking things all the time. It must be about having systems in place which tell you when things aren’t going well. It’s never quite as simple as being able to actually put your feet up, but certainly no system should require constant attention. It’s definitely a policy we at LobsterPot adhere to, whether it’s an alert to let us know that an ETL package has run successfully, or a script that generates some code for a report. If things can be automated, it reduces the chance of error, reduces the repetitive nature of work, and in general, keeps both consultants and clients much happier.

• That Escalated Quickly

  - by Jesse Taber

  Originally posted on: http://geekswithblogs.net/GruffCode/archive/2014/05/17/that-escalated-quickly.aspxI have been working remotely out of my home for over 4 years now. All of my coworkers during that time have also worked remotely. Lots of folks have written about the challenges inherent in facilitating communication on remote teams and strategies for overcoming them. A popular theme around this topic is the notion of “escalating communication”. In this context “escalating” means taking a conversation from one mode of communication to a different, higher fidelity mode of communication. Here are the five modes of communication I use at work in order of increasing fidelity: Email – This is the “lowest fidelity” mode of communication that I use. I usually only check it a few times a day (and I’m trying to check it even less frequently than that) and I only keep items in my inbox if they represent an item I need to take action on that I haven’t tracked anywhere else. Forums / Message boards – Being a developer, I’ve gotten into the habit of having other people look over my code before it becomes part of the product I’m working on. These code reviews often happen in “real time” via screen sharing, but I also always have someone else give all of the changes another look using pull requests. A pull request takes my code and lets someone else see the changes I’ve made side-by-side with the existing code so they can see if I did anything dumb. Pull requests can facilitate a conversation about the code changes in an online-forum like style. Some teams I’ve worked on also liked using tools like Trello or Google Groups to have on-going conversations about a topic or task that was being worked on. Chat & Instant Messaging  - Chat and instant messaging are the real workhorses for communication on the remote teams I’ve been a part of. I know some teams that are co-located that also use it pretty extensively for quick messages that don’t warrant walking across the office to talk with someone but reqire more immediacy than an e-mail. For the purposes of this post I think it’s important to note that the terms “chat” and “instant messaging” might insinuate that the conversation is happening in real time, but that’s not always true. Modern chat and IM applications maintain a searchable history so people can easily see what might have been discussed while they were away from their computers. Voice, Video and Screen sharing – Everyone’s got a camera and microphone on their computers now, and there are an abundance of services that will let you use them to talk to other people who have cameras and microphones on their computers. I’m including screen sharing here as well because, in my experience, these discussions typically involve one or more people showing the other participants something that’s happening on their screen. Obviously, this mode of communication is much higher-fidelity than any of the ones listed above. Scheduled meetings are typically conducted using this mode of communication. In Person – No matter how great communication tools become, there’s no substitute for meeting with someone face-to-face. However, opportunities for this kind of communcation are few and far between when you work on a remote team. When a conversation gets escalated that usually means it moves up one or more positions on this list. A lot of people advocate jumping to #4 sooner than later. Like them, I used to believe that, if it was possible, organizing a call with voice and video was automatically better than any kind of text-based communication could be. Lately, however, I’m becoming less convinced that escalating is always the right move. Working Asynchronously Last year I attended a talk at our local code camp given by Drew Miller. Drew works at GitHub and was talking about how they use GitHub internally. Many of the folks at GitHub work remotely, so communication was one of the main themes in Drew’s talk. During the talk Drew used the phrase, “asynchronous communication” to describe their use of chat and pull request comments. That phrase stuck in my head because I hadn’t heard it before but I think it perfectly describes the way in which remote teams often need to communicate. You don’t always know when your co-workers are at their computers or what hours (if any) they are working that day. In order to work this way you need to assume that the person you’re talking to might not respond right away. You can’t always afford to wait until everyone required is online and available to join a voice call, so you need to use text-based, persistent forms of communication so that people can receive and respond to messages when they are available. Going back to my list from the beginning of this post for a second, I characterize items #1-3 as being “asynchronous” modes of communication while we could call items #4 and #5 “synchronous”. When communication gets escalated it’s almost always moving from an asynchronous mode of communication to a synchronous one. Now, to the point of this post: I’ve become increasingly reluctant to escalate from asynchronous to synchronous communication for two primary reasons: 1 – You can often find a higher fidelity way to convey your message without holding a synchronous conversation 2 - Asynchronous modes of communication are (usually) persistent and searchable. You Don’t Have to Broadcast Live Let’s start with the first reason I’ve listed. A lot of times you feel like you need to escalate to synchronous communication because you’re having difficulty describing something that you’re seeing in words. You want to provide the people you’re conversing with some audio-visual aids to help them understand the point that you’re trying to make and you think that getting on Skype and sharing your screen with them is the best way to do that. Firing up a screen sharing session does work well, but you can usually accomplish the same thing in an asynchronous manner. For example, you could take a screenshot and annotate it with some text and drawings to illustrate what it is you’re seeing. If a screenshot won’t work, taking a short screen recording while your narrate over it and posting the video to your forum or chat system along with a text-based description of what’s in the recording that can be searched for later can be a great way to effectively communicate with your team asynchronously. I Said What?!? Now for the second reason I listed: most asynchronous modes of communication provide a transcript of what was said and what decisions might have been made during the conversation. There have been many occasions where I’ve used the search feature of my team’s chat application to find a conversation that happened several weeks or months ago to remember what was decided. Unfortunately, I think the benefits associated with the persistence of communicating asynchronously often get overlooked when people decide to escalate to a in-person meeting or voice/video call. I’m becoming much more reluctant to suggest a voice or video call if I suspect that it might lead to codifying some kind of design decision because everyone involved is going to hang up the call and immediately forget what was decided. I recognize that you can record and archive these types of interactions, but without being able to search them the recordings aren’t terribly useful. When and How To Escalate I don’t mean to imply that communicating via voice/video or in person is never a good idea. I probably jump on a Skype call with a co-worker at least once a day to quickly hash something out or show them a bit of code that I’m working on. Also, meeting in person periodically is really important for remote teams. There’s no way around the fact that sometimes it’s easier to jump on a call and show someone my screen so they can see what I’m seeing. So when is it right to escalate? I think the simplest way to answer that is when the communication starts to feel painful. Everyone’s tolerance for that pain is different, but I think you need to let it hurt a little bit before jumping to synchronous communication. When you do escalate from asynchronous to synchronous communication, there are a couple of things you can do to maximize the effectiveness of the communication: Takes notes – This is huge and yet I’ve found that a lot of teams don’t do this. If you’re holding a meeting with  > 2 people you should have someone taking notes. Taking notes while participating in a meeting can be difficult but there are a few strategies to deal with this challenge that probably deserve a short post of their own. After the meeting, make sure the notes are posted to a place where all concerned parties (including those that might not have attended the meeting) can review and search them. Persist decisions made ASAP – If any decisions were made during the meeting, persist those decisions to a searchable medium as soon as possible following the conversation. All the teams I’ve worked on used a web-based system for tracking the on-going work and a backlog of work to be done in the future. I always try to make sure that all of the cards/stories/tasks/whatever in these systems always reflect the latest decisions that were made as the work was being planned and executed. If held a quick call with your team lead and decided that it wasn’t worth the effort to build real-time validation into that new UI you were working on, go and codify that decision in the story associated with that work immediately after you hang up. Even better, write it up in the story while you are both still on the phone. That way when the folks from your QA team pick up the story to test a few days later they’ll know why the real-time validation isn’t there without having to invoke yet another conversation about the work. Communicating Well is Hard At this point you might be thinking that communicating asynchronously is more difficult than having a live conversation. You’re right: it is more difficult. In order to communicate effectively this way you need to very carefully think about the message that you’re trying to convey and craft it in a way that’s easy for your audience to understand. This is almost always harder than just talking through a problem in real time with someone; this is why escalating communication is such a popular idea. Why wouldn’t we want to do the thing that’s easier? Easier isn’t always better. If you and your team can get in the habit of communicating effectively in an asynchronous manner you’ll find that, over time, all of your communications get less painful because you don’t need to re-iterate previously made points over and over again. If you communicate right the first time, you often don’t need to rehash old conversations because you can go back and find the decisions that were made laid out in plain language. You’ll also find that you get better at doing things like writing useful comments in your code, creating written documentation about how the feature that you just built works, or persuading your team to do things in a certain way.

• Would You Like It In Green?

  - by steve.diamond

  OK, so admittedly, this is already a TIRED and HACKNEYED term, but it applies here, so please endure the following. If you would like it in green, then yes, "We have an app for that!" In the soon-to-be-introduced next release of Oracle CRM On Demand, organizations gain unprecedented flexibility in their ability to optimize the look and feel of the Oracle CRM On Demand user interface. So if you want it in green, you can have it in green. And on this topic, I must say...our product development team seems to be taking unabashed pleasure in displaying this new color flexibility. Their demos are increasingly displaying a color palette that would make Martha Stewart hurl. And when I offer any feedback in my typically "direct" manner, they respond with, "Well Diamond, we can't show red or blue now, can we? It would just look like...everything else!" Yeah....but....but...I'm wearing a white shirt today, just like the white shirt I wore yesterday. And my wife has a fondness for "Shabby Chic," which is an interior design style deploying mostly white backdrops. Therefore, I guess I'm not the best one to critique. In all seriousness, although we'll be profiling far meatier features in the next release of Oracle CRM On Demand, this is important for organizations that want to match the look and feel of their CRM application to their corporate branding standards. Oh, and Happy St. Patrick's Day.

• Static objects and concurrency in a web application

  - by Ionut

  I'm developing small Java Web Applications on Tomcat server and I'm using MySQL as my database. Up until now I was using a connection singleton for accessing the database but I found out that this will ensure just on connection per Application and there will be problems if multiple users want to access the database in the same time. (They all have to make us of that single Connection object). I created a Connection Pool and I hope that this is the correct way of doing things. Furthermore it seems that I developed the bad habit of creating a lot of static object and static methods (mainly because I was under the wrong impression that every static object will be duplicated for every client which accesses my application). Because of this all the Service Classes ( classes used to handle database data) are static and distributed through a ServiceFactory: public class ServiceFactory { private static final String JDBC = "JDBC"; private static String impl; private static AccountService accountService; private static BoardService boardService; public static AccountService getAccountService(){ initConfig(); if (accountService == null){ if (impl.equalsIgnoreCase(JDBC)){ accountService = new JDBCAccountService(); } } return accountService; } public static BoardService getBoardService(){ initConfig(); if (boardService == null){ if (impl.equalsIgnoreCase(JDBC)){ boardService = new JDBCBoardService(); } } return boardService; } private static void initConfig(){ if (StringUtil.isEmpty(impl)){ impl = ConfigUtil.getProperty("service.implementation"); // If the config failed initialize with standard if (StringUtil.isEmpty(impl)){ impl = JDBC; } } } This was the factory class which, as you can see, allows just one Service to exist at any time. Now, is this a bad practice? What happens if let's say 1k users access AccountService simultaneously? I know that all this questions and bad practices come from a bad understanding of the static attribute in a web application and the way the server handles this attributes. Any help on this topic would be more than welcomed. Thank you for your time!

• CIC 2010 - Ghost Stories and Model Based Design

  - by warren.baird

  I was lucky enough to attend the collaboration and interoperability congress recently. The location was very beautiful and interesting, it was held in the mountains about two hours outside Denver, at the Stanley hotel, famous both for inspiring Steven King's novel "The Shining" and for attracting a lot of attention from the "Ghost Hunters" TV show. My visit was prosaic - I didn't get to experience the ghosts the locals promised - but interesting, with some very informative sessions. I noticed one main theme - a lot of people were talking about Model Based Design (MBD), which is moving design and manufacturing away from 2d drawings and towards 3d models. 2d has some pretty deep roots in industrial manufacturing and there have been a lot of challenges encountered in making the leap to 3d. One of the challenges discussed in several sessions was how to get model information out to the non-engineers in the company, which is a topic near and dear to my heart. In the 2D space, people without access to CAD software (for example, people assembling a product on the shop floor) can be given printouts of the design - it's not particularly efficient, and it definitely isn't very green, but it tends to work. There's no direct equivalent in the 3D space. One of the ways that AutoVue is used in industrial manufacturing is to provide non-CAD users with an easy to use, interactive 3D view of their products - in some cases it's directly used by people on the shop floor, but in cases where paper is really ingrained in the process, AutoVue can be used by a technical publications person to create illustrative 2D views that can be printed that show all of the details necessary to complete the work. Are you making the move to model based design? Is AutoVue helping you with your challenges? Let us know in the comments below.

• Silverlight Firestarter 2010 Keynote with Scott Guthrie: Silverlight has a bright future!

  - by Jim Duffy

  If you didn’t get chance to watch the Silverlight Firestart event live during the webcast it is available online to view now. If you’re a Silverlight developer or perhaps a shop actively planning on developing a Silverlight application then you’re going to want to watch this video. The Silverlight 5 feature set unveiled during the keynote is fantastic! I particularly like Scott’s approach and comments on the future of Silverlight. I appreciated his open and direct acknowledgment that there has “been a lot of angst on this topic in the last few weeks” and he took the bull by the horns and stated “Let me say up front that there is a Silverlight future, and we think it’s going to be a very bright one.” That comment drew applause from the local audience and in our local viewing event held in Raleigh, NC. Of course my first question was when can we get our grubby little hands on Silverlight 5 and start working with it. The answer unfortunately wasn’t “right now” but they did announce the Silverlight 5 beta will be available in the first half of 2011. Of course the following is pure speculation on my part but I wouldn’t be surprised if they made it available at a certain event in April 2011. Additional information about the Silverlight 5 announcement is available on Scott’s blog. Have a day.

• Are there any font rendering libraries for games development that support hinting?

  - by Richard Fabian

  I've used angel code's bitmap font generator quite a bit and though it's very good, I wondered if there would be a way of using the hinting information to provide a better readable result by using hinting to provide differing thickness based on size/pixel coverage. I imagine any solution would have to use the distance field tech presented in the valve paper on smoothing fonts while maintaining or reducing asset size. (http://www.gamedev.net/community/forums/topic.asp?topic_id=494612) but I haven't found any demos of it being used with hinting information turned on or included in the field gradients in any way. Another way of looking at this is whether there are any font bitmap generators that will output mipmaps that still maintain their readability in the face of pixel size. I think the lower mip levels would try to guarantee fill and space where it is necessary to maintain readability/topology over maintaining style/form (the point of hinting). In response to "Is there a reason you can't just render the size you want", the problem lies in the fact that font rasterisers currently don't render in 3D, and hinting information would be important in different amounts due to the pixel density being different along different axes, even differing in importance along the length of a string due to the size reducing over distance. For example, I only want horizontal hinting in a texture that is viewed from the side, and only really want vertical hinting in a font that is viewed from below or above. This isn't meant to be a renderer that tries to render a perfect outline as accurately as possible, as hinting distorts the reality of the font, instead this is meant to be a rendering solution for quite static scenes, but scenes that have 3D transformed and warped text layout. In this case the legibility is important, more important than the accuracy of representation of the polygon shape.

• How to Setup an Active Directory Domain-Week 26

  - by OWScott

  Today's lesson covers how to create an Active Directory domain and join a member server to it. This week's topic takes a slightly different turn from the normally IIS related topics, but this is key video to help setup either a test or production environment that requires Active Directory. Part of being a web administrator is understanding the servers and how they interact with each other. This week’s lesson takes a different path than usual and covers how to create an Active Directory domain and how to join a member computer to that domain. In less than 13 minutes we complete the entire process, end to end. An understanding of Active Directory is useful, whether it’s simply to setup a test lab, or to learn more so that you can manage a production domain environment. This week starts a mini-series on web farms. Today’s lesson is on setting up a domain which is a necessary prerequisite for next week which will be on Distributed File System Replication (DFS-R), a useful technology for web farms. Upcoming lessons will cover shared configuration, Application Request Routing (ARR), and more. Additionally, this video introduces us to Vaasnet (www.vaasnet.com), a service that allows the web pro to gain immediate access to an entire lab environment for situations such as these. This is week 26 (the middle week!) of a 52 week series for the Web Pro. Past and future videos can be found here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.

• Writing a Book, and Moving my Blog

  - by Ben Nevarez

  I started blogging about SQL Server here at SQLblog back in July, 2009 and it was a lot of fun, I enjoyed it a lot. Then later, after a series of blog posts about the Query Optimizer, I was invited to write an entire book about that same topic. But after a few months I realized that it was going to be hard to continue both blogging and writing chapters for a book, this in addition to my regular day job, so I decided to stop blogging for a little while.   Now that I have finished the last chapter of the book and I am working on the final chapter reviews, I decided to start blogging again. This time I am moving my blog to   http://www.benjaminnevarez.com   Same as my previous posts I plan to write about my topics of interest, like the relational engine, and basically anything related to SQL Server. Hopefully you find my new blog interesting and useful.   Finally, I would like to thank Adam for allowing me to blog here.

• "Has Oracle written the script for CRM success?" - Anthony Lye on Customer Experience at BAFTA

  - by Richard Lefebvre

  Anthony Lye showcased Oracle Fusion CRM at a BAFTA gathering, and MyCustomer.com covered the story under the title of "Has Oracle written the script for CRM success?' According to MyCustomer.com, "Oracle's SVP of CRM Anthony Lye set the scene for the event, suggesting products are becoming commoditized, so that the only way to differentiate is through the relationship with the customer. But he warned that "customers are more and more in control of that relationship, so you have to provide great experiences for them." "The quickest win within your organization to create a single view is to connect your marketing organization with your selling organization, align goals, processes, people and technology," Anthony explained.   "And this is a transition that is already happening - "VPs of marketing have started turning up in the same meetings as VPs of sales, we have started to see that they want to work together" - but this convergence needs nurturing." "In Fusion there are capabilities to align the organisation - we enable marketing on the same platform to build campaigns connected to sales stages. It can affect leads and opportunities at the top end of the funnel. And the selling organisation can take advantage of marketing content - the materials that are exclusively within marketing can now be used by sales. Your sales teams have been campaigning forever, but it's usually by email, it isn't aligned with the corporate message and it's being sent to people it shouldn't. By aligning them we can increase output and the quality of that output." Anthony concluded: "Operating in a disconnected fashion having two distinct systems will cost you time and money. So we feel there's a material advantage in a solution like this." Enjoy the full story at http://www.mycustomer.com/topic/marketing/has-oracle-written-script-crm-success/139958

• GPLv2 - Multiple AI chess engines to bypass GPL

  - by Dogbert

  I have gone through a number of GPL-related questions, the most recent being this one: http://stackoverflow.com/questions/3248823/legal-question-about-the-gpl-license-net-dlls/3249001#3249001 I'm trying to see how this would work, so bear with me. I have a simple GUI interface for a game of Chess. It essentially can send/receive commands to/from an external chess engine (ie: Tong, Fruit, etc). The application/GUI is similar in nature to XBoard ( http://www.gnu.org/software/xboard/ ), but was independently designed. After going through a number of threads on this topic, it seems that the FSF considers dynamically linking against a GPLv2 library as a derivative work, and that by doing so, the GPLv2 extends to my proprietary code, and I must release the source to my entire project. Other legal precedents indicate the opposite, and that dynamic linking doesn't cause the "viral" effect of the GPL to propagate to my proprietary code. Since there is no official consensus that can give a "hard-and-fast" answer to the dynamic linking question, would this be an acceptable alternative: I build my chess GUI so that it sends/receives the chess engine AI logic as text commands from an external interface library that I write The interface library I wrote itself is then released under the GPL The interface library is only used to communicate via a generic text pipe to external command-line chess engines The chess engine itself would be built as a command-line utility rather than as a library of any sort, and just sends strings in the Universal Chess Interface of Chess Engine Communication Protocol ( http://en.wikipedia.org/wiki/Chess_Engine_Communication_Protocol ) format. The one "gotcha" is that the interface library should not be specific to one single GPL'ed chess engine, otherwise the entire GUI would be "entirely dependent" on it. So, I just make my interface library so that it is able to connect to any command-line chess engine that uses a specific format, rather than just one unique engine. I could then include pre-built command-line-app versions of any of the chess engines I'm using. Would that sort of approach allow me to do the following: NOT release the source for my UI Release the source of the interface library I built (if necessary) Use one or more chess engines and bundle them as external command-line utilities that ship with a binary version of my UI Thank you.

• MSCC: Purpose and benefits of Version Control Systems (VCS)

  Unfortunately, there was no monthly meetup during May. Which means that it was even more important and interesting to go forward with a great topic for this month. Earlier this year I already spoke to Nayar Joolfoo about doing a presentation on version control systems (VCS), and he gladly agreed since then. It was just about finding the right date for the action. Furthermore, it was also a great coincidence that Avinash Meetoo announced on social media networks that Knowledge 7 is about to have a new training on "Effective git" - which correlates to a book title Avinash is currently working on - all the best with your approach on this and reach out to our MSCC craftsmen for recessions. Once again a big Thank you to Orange Ebene Accelerator on providing the venue for us, and the MSCC members involved on securing the time slot for our event. Unfortunately, it's kind of tough to get an early confirmation for our meetups these days. I'll keep you posted on that one as there are some interesting and exciting options coming up soon. Okay, let's talk about the meeting and version control systems again. As usual, I'm going to put my first impression of the meetup: "Absolutely great topic, questions and discussions on version control systems, like git or VSO. I was also highly pleased by the number of first timers and female IT geeks. Hopefully, we will be able to keep this trend for future get-togethers." And I really have to emphasise the amount of fresh blood coming to our gathering. Also, during the initial phase it was surprising to see that exactly those first-timers, most of them students at various campuses here on the island, had absolutely no idea about version control systems. More about further down... Reactions of other attendees If I counted correctly, we had a total of 17 attendees this month, and I'd like to give you feedback from some of them: "Inspiring. Helped me understand more about GIT." -- Sean on event comments "Joined the meetup today with literally no idea what is a version control system. I have several reasons why I should be starting to use VCS as from NOW in my projects. Thanks Nayar, Jochen and other participants :)" -- Yudish on event comments "Was present today and I'm very satisfied.I was not aware if there was a such tool like git available. Thanks to those who contributed for this meetup.It was great. Learned a lot from this meetup!!" -- Leonardo on event comments "Seriously, I can see how it’s going to ease my task and help me save time. Gone are the issues with files backups.  And since I’ll be doing my dissertation this year, using Git would help me a lot for my backups and I’m grateful to Nayar for the great explanation." -- Swan-Iyah on MSCC meetup : Version Controls Hopefully, I'll be able to get some other sources - personal blogs preferred - on our meeting. Geeks, thank you so much for those encouraging comments. It's really great to experience that we, all members of the MSCC, are doing the right thing to get more IT information out, and to help each other to improve and evolve in our professional careers. Our agenda of the day Honestly, we had a bumpy start... First, I was battling a little bit with the movable room divider in order to maximize the space. I mean, we had 24 RSVPs and usually there might additional people coming along. Then, for what ever reason, we were facing power outages - actually twice in short periods. Not too good for the projector after all, but hey it went smooth for the rest of the time being. And last but not least... our first speaker Nayar got stuck somewhere on the road. ;-) Anyway, not a real show-stopper and we used the time until Nayar's arrival to introduce ourselves a little bit. It is always important for me to get to know the "newbies" a little bit, and as a result we had lots of students of university - first year, second year and recent graduates - among them. Surprisingly, none of them was ever in contact with version control systems at all. I mean, this is a shocking discovery! Similar to the ability of touch-typing I'd say that being able to use (and master) any kind of version control system is compulsory in any job in the IT industry. Seriously, I'm wondering what is being taught during the classes on the campus. All of them have to work on semester assessments or final projects, even in small teams of 2-4 people. That's the perfect occasion to get started with VCS. Already in this phase, we had great input from more experienced VCS users, like Sean, Avinash and myself. git - a modern approach to VCS - Nayar What a tour! Nayar gave us the full round of git from start to finish, even touching some more advanced techniques. First, he started to explain about the importance of version control systems as an essential tool for software developers, even working alone on a project, and the ability to have a kind of "time machine" that allows you to inspect and revert to a previous version of source code at any time. Then he showed how easy it is to install git on an Ubuntu based system but also mentioned that git is literally available for any operating system, like Windows, Mac OS X and of course other Linux distributions. Next, he showed us how to set the initial configuration values of user name and email address which simplifies the daily usage of the git client while working with your repositories. Then he initialised and added a new repository for some local development of a blogging software. All commands were done using the command line interface (CLI) so that they can be repeated on any system as reference. The syntax and the procedure is always the same, and Nayar clearly mentioned this to the attendees. Now, having a git repository in place it was about time to work on some "important" changes on the blogging software - just for the sake of demonstrating the ease of use and power of git. One interesting question came very early: "How many commands do we have to learn? It looks quite difficult at the moment" - Well, rest assured that during daily development circles you will need less than 10 git commands on a regular base: git add, commit, push, pull, checkout, and merge And Nayar demo'd all of them. Much to the delight of everyone he also showed gitk which is the git repository browser. It's an UI tool to display changes in a repository or a selected set of commits. This includes visualizing the commit graph, showing information related to each commit, and the files in the trees of each revision. Using gitk to display and browse information of a local git repository And last but not least, we took advantage of the internet connectivity and reached out to various online portals offering git hosting for free. Nayar showed us how to push the local repository into a remote system on github. Showing the web-based git browser and history handling, and then also explained and demo'd on how to connect to existing online repositories in order to get access to either your own source code or other people's open source projects. Next to github, we also spoke about bitbucket and gitlab as potential online platforms for your projects. Have a look at the conditions and details about their free service packages and what you can get additionally as a paying customer. Usually, you already get a lot of services for up to five users for free but there might be other important aspects that might have an impact on your decision. Anyways, moving git-based repositories between systems is a piece of cake, and changing online platforms is possible at any stage of your development. Visual Studio Online (VSO) - Jochen Well, Nayar literally covered all elements of working with git during his session, including the use of external online platforms. So, what would be the advantage of talking about Visual Studio Online (VSO)? First of all, VSO is "just another" online platform for hosting and managing git repositories on remote systems, equivalent to github, bitbucket, or any other web site. At the moment (of writing), Microsoft also provides a free package of up to five users / developers on a git repository but there is more in that package. Of course, it is related to software development on the Windows systems and the bonds are tightened towards the use of Visual Studio but out of experience you are absolutely not restricted to that. Connecting a Linux or Mac OS X machine with a git client or an integrated development environment (IDE) like Eclipse or Xcode works as smooth as expected. So, why should one opt in for VSO? Well, one of the main aspects that I would like to mention here is that VSO integrates the Application Life Cycle Methodology (ALM) of Microsoft in their platform. Meaning that you get agile project management with Backlogs, Sprints, Burn-down charts as well as the ability to track tasks, bug reports and work items next to collaborative team chats. It's the whole package of agile development you'll get. And, something I mentioned briefly during the begin of our meeting, VSO gives you the possibility of an automated continuous integrated (CI) process which builds and can run tests of your source code after each commit of changes. Having a proper CI strategy is also part of the Clean Code Developer practices - on Level Green actually -, and not only simplifies your life as a software developer but also reduces the sources of potential errors. Seamless integration and automated deployment between Microsoft Azure Web Sites and git repository But my favourite feature is the seamless continuous deployment to Microsoft Azure. Especially, while working on web projects it's absolutely astounishing that as soon as you commit your chances it just takes a couple of seconds until your modifications are deployed and available on your Azure-hosted web sites. Upcoming Events and networking Due to the adjusted times, everybody was kind of hungry and we didn't follow up on networking or upcoming events - very unfortunate to my opinion and this will have an impact on future planning of our meetups. Because I rather would like to see more conversations during and at the end of our meetings than everyone just packing their laptops, bags and accessories and rush off to grab some food. I was hoping to get some information regarding this year's Code Challenge - supposedly to be organised during July? Maybe someone could leave a comment on that - but I couldn't get any updates. Well, I'll keep digging... In case that you would like to get more into git and how to use it effectively, please check out Knowledge 7's upcoming course on "Effective git". Thanks Avinash for your vital input into today's conversation and I'm looking forward to get a grip on your book title very soon. My resume of the day Do not work in IT without any kind of version control system! Seriously, without a VCS in place you're doing it wrong. It's like driving a car without seat belts attached or riding your bike without safety helmet. You don't do that! End of discussion. ;-) Nowadays, having access to free (as in cost) tools to install on your machine and numerous online platforms to host your source code for free for up to five users it's a no-brainer to get yourself familiar with VCS. Today's sessions gave a good overview on how to start using git and how to connect to various remote services like github or VSO.

• How to explain my 5 burnt-out years off to a new employer?

  - by user17332

  Five years ago, I lost my ability to concentrate long-term, and therefore ability to code with professional efficiency. I know why it happened, I understood how it happened, and on top of being able to re-create my calm and thus relaxed focus, I overcame the original (rooted in childhood) reason why my mind tilted on the overall situation back then; My understanding isn't rooted in words that a psychologist told me, I actually grokked them first-hand. I'm pretty much confident to be able to churn out productivity, possibly even more so than pre-burnout. I also never lost my interest in code nor did I stray from trying to get my abilities back; I kept my knowledge up to date (I could always relatively painlessly learn things coding-related, just not apply them) and thus can say that I'm a better developer than before, even if my average LOC-count over those years is abysmally low. On the other hand, now I have a biography that includes more time on the dole than in a job. What would convince you, as an employer, to give my application a chance? I don't believe I should just keep the whole topic out of it.

• CRM at Oracle Series: Do Not Call & Do Not Email

  - by tony.berk

  Who you gonna call? Or not call! Sorry, just kidding, this isn't a movie blog! Do Not Call is an important topic for all businesses as there are government regulations that can lead to significant fines, and of course, possible damage to your brand. Oracle leverages Siebel CRM to develop an effective solution to address the Do Not Call and Email Permissible Use requirements. The application uses the Contacts functionality to manage communication preferences, which when defined, centrally synchronizes all contact records that share the same phone number and email address. Additionally, the relevant information is masked so Oracle employees cannot accidentally reach out to the contact. Therefore, the solution ensures that we are compliant with regulations, enables us to respect individuals' communication preferences and provides an audit trail of changes to their preferences. Today's CRM at Oracle slidecast discusses the requirements, highlights benefits and provides screen shots of the solution. CRM at Oracle Series: Do Not Call & Do Not Email Click here to learn more about Siebel CRM and other Oracle CRM products. Are you enjoying the CRM at Oracle Series? We are working on more topics for this year, but if there is a particular CRM area or function which you'd like to hear how Oracle implemented it internally, leave us a comment and we'll try to get it on our list.

• SQL SERVER – A Funny Cartoon on Index

  - by pinaldave

  Performance Tuning has been my favorite subject and I have done it for many years now. Today I will list one of the most common conversation about Index I have heard in my life. Every single time, I am at consultation for performance tuning I hear following conversation among various team members. I want to ask you, does this kind of conversation happens in your organization? Any way, If you think Index solves all of your performance problem I think it is not true. There are many other reason one has to consider along with Indexes. For example I consider following various topic one need to understand for performance tuning. ?Logical Query Processing ?Efficient Join Techniques ?Query Tuning Considerations ?Avoiding Common Performance Tuning Issues Statistics and Best Practices ?TempDB Tuning ?Hardware Planning ?Understanding Query Processor ?Using SQL Server 2005 and 2008 Updated Feature Sets ?CPU, Memory, I/O Bottleneck Index Tuning (of course) ?Many more… Well, I have written this blog thinking I will keep this blog post a bit easy and not load up. I will in future discuss about other performance tuning concepts. Let me know what do you think about the cartoon I made.

• Is “Application Programming Interface” a bad name?

  - by Taylor Hawkes

  Application programming interface seems like a bad name for what it is. Is there a reason it was named such? I understand that people used to call them Advanced Programming Interfaces and then renamed to Application Programming Interface. Is that why it is poorly named? Why is it not named Application (to) Programmer Interface. I guess I'm just confused of the meaning behind that name? I write more about my confusion around the name here: BREAKING DOWN THE WORD “APPLICATION PROGRAMMING INTERFACE” This is a very confusing word. We mostly understand what the word Interface means, but “Application Programming”, what even is that. Honestly I'm confused. Is that suppose to be two words like “Application”, “Programming” and then the “Interface” is suppose to mean between the two? Like would a “Computer Human Interface” be an interface between a “Computer” and a “Human” (monitor , keyboard, mouse ) or is a “Computer Human” a real thing - perhaps the terminator. So a CHI is our boy Kyle Reese who is the only way we are able to work with the computer human. I think more likely “Application Programming Interface” was simply poorly named and doesn't really make sense. It was originally called an “Advanced Programming Interface” , but perhaps being a bit to ostentatious merged into the now wildly accepted “Application Programming Interface”. So now, not wanting to change an acronym has confused the living heck out everyone.... Any thoughts or clarification would be great, I'm giving a lecture on this topic in a month, so I would prefer not to BS my way through it.

• DTrace for Oracle Linux news: new beta release and conference appearances

  - by Lenz Grimmer

  A new set of RPM packages of our port of DTrace for Linux has just been published on the Unbreakable Linux Network. This is another beta release of our ongoing development effort to bring the DTrace framework to Linux. This release includes the following changes: The packages are now based on the final public release of the Unbreakable Enterprise Kernel Release 2 (2.6.39). The previous beta drop was based on a development version of the 2.6.39 kernel; there is no new functionality specific to DTrace in this release. The primary goal was to get the code base in sync with the released kernel version. Based on the feedback we received from some users in how their applications interact with dtrace, libdtrace is now a shared library. However, the API/ABI is not fully stabilized yet and may be subject to change. As a result of the ongoing QA testing, some test cases were reorganized into their own subdirectories, which allows running the test suite in a more fine-grained manner. As reminder, we have a dedicated Forum for DTrace on Linux, to discuss your experiences with this release. This week, the Linux DTrace team also attendeded the second dtrace.conf in San Francisco, to talk about their work. The sessions were streamed live and recordings are also available. You can watch Oracle's Kris Van Hees' talk below: Video streaming by Ustream We would like to thank the dtrace.conf organizers for the speaking opportunity and for organizing this event! This Wednesday (April 4th), Kris and Elena Zannoni also spoke on this topic at the Linux Foundation Collaboration Summit 2012 in San Francisco, CA. The slides are now available for download (PDF).

• BIEE Drilling Down and then Across

  - by Tim Dexter

  Slightly off topic today but if you are working with OBIEE in conjunction with BIP its not that far off. Some of you may know, I now get to play with the whole BI suite, I have been for nearly 2 years. Today, I was working with BIEE and wanted to share what I thought was a neat trick. I have to thank Rob Lindsley on our team for the pointers to get it working. The problem I had was that I had set up a drill down hierarchy that took the user down a couple of levels to the bottom project number level. I needed for the user to then be able to click the project number to navigate across to another more detailed report on that project. By default, there is no link, you are at the bottom of a hierarchical drill! There is nothing you can do in the data model (that Im aware of) but you can use a neat trick to get BIEE to allow you to navigate from the bottom rung of the hierarchy. Add the bottom level column to an Answer report. Go into the column properties and set the navigation target. The trick is to then set the current column properties as the system-wide default for that column. You can then actually delete the column from your report. Now as you drill down the hierarchy and reach what was the bottom you will still have a link for the user to punch over to the detail report, sweeeet! The other benefit is that whenever you add the column to a report the link will be available to the detail report, unless you want to override it of course.
