  • Outbound ports to allow through firewall

    - by dunxd
    This question was asked before, but in a rather general way. I'm asking more specifically based on my current requirements. We have a number of remote offices made up of a bunch of PCs and an ASA 5505 which is used as firewall and VPN termination point. In the offices we share the internet connection with one or more other organisations over whom we have very little control, asides from the config on the ASAs. For a bunch of reasons I'd like to lock down these ASA 5505s to only allow outbound traffic to ports used by applications we know we need. I'm putting a standard config to roll out to all the ASAs, and if we need to open up ports for the other orgs we can do it on request. But I want to leave open the most commonly required ports so we can get up and running without waiting on other folks technical staff to get back. I plan to allow the following TCP ports to support commonly required resources: POP3 (110 and 995) HTTP (80 and 443) IMAP4 (143 and 993) SMTP (25 and and 465) The question really is, what other ports do I need to leave open to allow for "normal" working. I've seen UDP port 53 for DNS as one. Are there any others that would be worth opening up? Just to note - I'll also be setting up monitoring systems to keep an eye on the ports we do allow. Any of the above could be misused of course. We'll also back all this up with signed agreements. But I'm aiming for a technical solutions where I don't have to start out with the full requirements of everyone we share connections with. See also: outbound ports that are always open

  • Cloud Based Load Testing Using TF Service &amp; VS 2013

    - by Tarun Arora [Microsoft MVP]
    Originally posted on: http://geekswithblogs.net/TarunArora/archive/2013/06/30/cloud-based-load-testing-using-tf-service-amp-vs-2013.aspx One of the new features announced as part of the Visual Studio 2013 Ultimate Preview is ‘Cloud Based Load Testing’. In this blog post I’ll walk you through, What is Cloud Based Load Testing? How have I been using this feature? – Success story! Where can you find more resources on this feature? What is Cloud Based Load Testing? It goes without saying that performance testing your application not only gives you the confidence that the application will work under heavy levels of stress but also gives you the ability to test how scalable the architecture of your application is. It is important to know how much is too much for your application! Working with various clients in the industry I have realized that the biggest barriers in Load Testing & Performance Testing adoption are, High infrastructure and administration cost that comes with this phase of testing Time taken to procure & set up the test infrastructure Finding use for this infrastructure investment after completion of testing Is cloud the answer? 100% Visual Studio Compatible Scalable and Realistic Start testing in < 2 minutes Intuitive Pay only for what you need Use existing on premise tests on cloud There are a lot of vendors out there offering Cloud Based Load Testing, to name a few, Load Storm Soasta Blaze Meter Blitz And others… The question you may want to ask is, why should you go with Microsoft’s Cloud based Load Test offering. If you are a Microsoft shop or already have investments in Microsoft technologies, you’ll see great benefit in the natural integration this offers with existing Microsoft products such as Visual Studio and Windows Azure. For example, your existing Web tests authored in Visual Studio 2010 or Visual Studio 2012 will run on the cloud without requiring any modifications what so ever. Microsoft’s cloud test rig also supports API based testing, for example, if you are building a WPF application which consumes WCF services, you can write unit tests to invoke the WCF service, these tests can be run on the cloud test rig and loaded with ‘N’ concurrent users for performance testing. If you have your assets already hosted in the Azure and possibly in the same data centre as the Cloud test rig, your Azure app will not incur a usage cost because of the generated traffic since the traffic is coming from the same data centre. The licensing or pricing information on Microsoft’s cloud based Load test service is yet to be announced, but I would expect this to be priced attractively to match the market competition.   The only additional configuration required for running load tests on Microsoft Cloud based Load Tests service is to select the Test run location as Run tests using Visual Studio Team Foundation Service, How have I been using Microsoft’s Cloud based Load Test Service? I have been part of the Microsoft Cloud Based Load Test Service advisory council for the last 7 months. This gave the opportunity to see the product shape up from concept to working solution. I was also the first person outside of Microsoft to try this offering out. This gave me the opportunity to test real world application at various clients using the Microsoft Load Test Service and provide real world feedback to the Microsoft product team. One of the most recent systems I tested using the Load Test Service has been an insurance quote generation engine. This insurance quote generation engine is,   hosted in Windows Azure expected to get quote requests from across the globe expected to handle 5 Million quote requests in a day (not clear how this load will be distributed across the day) There was no way, I could simulate such kind of load from on premise without standing up additional hardware. But Microsoft’s Cloud based Load Test service allowed me to test my key performance testing scenarios, i.e. Simulate expected Load, Endurance Testing, Threshold Testing and Testing for Latency. Simulating expected load: approach to devising a load pattern My approach to devising a load test pattern has been to run the test scenario with 1 user to figure out the response time. Then work out how many users are required to reach the target load. So, for example, to invoke 1 quote from the quote engine software takes 0.5 seconds. Now if you do the math,   1 quote request by 1 user = 0.5 seconds   quotes generated by 1 user in 24 hour = 1 * (((2 * 60) * 60) * 24) = 172,800   quotes generated by 30 users in 24 hours = 172,800 * 30 =  5,184,000 This was a very simple example, if your application requires more concurrent users to test scenario’s such as caching, etc then you can devise your own load pattern, some examples of load test patterns can be found here.  Endurance Testing To test for endurance, I loaded the quote generation engine with an expected fixed user load and ran the test for very long duration such as over 48 hours and observed the affect of the long running test on the Azure infrastructure. Currently Microsoft Load Test service does not support metrics from the machine under test. I used Azure diagnostics to begin with, but later started using Cerebrata Azure Diagnostics Manager to capture the metrics of the machine under test. Threshold Testing To figure out how much user load the application could cope with before falling on its belly, I opted to step load the quote generation engine by incrementing user load with different variations of incremental user load per minute till the application crashed out and forced an IIS reset. Testing for Latency Currently the Microsoft Load Test service does not support generating geographically distributed load, I however, deployed the insurance quote generation engine in different Azure data centres and ran the same set of performance tests to measure for latency. Because I could compare load test results from different runs by exporting the results to excel (this feature is provided out of the box right from Visual Studio 2010) I could see the different in response times.

  • Conducting Effective Web Meetings

    - by BuckWoody
    There are several forms of corporate communication. From immediate, rich communications like phones and IM messaging to historical transactions like e-mail, there are a lot of ways to get information to one or more people. From time to time, it's even useful to have a meeting. (This is where a witty picture of a guy sleeping in a meeting goes. I won't bother actually putting one here; you're already envisioning it in your mind) Most meetings are pointless, and a complete waste of time. This is the fault, completely and solely, of the organizer. It's because he or she hasn't thought things through enough to think about alternate forms of information passing. Here's the criteria for a good meeting - whether in-person or over the web: 100% of the content of a meeting should require the participation of 100% of the attendees for 100% of the time It doesn't get any simpler than that. If it doesn't meet that criteria, then don't invite that person to that meeting. If you're just conveying information and no one has the need for immediate interaction with that information (like telling you something that modifies the message), then send an e-mail. If you're a manager, and you need to get status from lots of people, pick up the phone.If you need a quick answer, use IM. I once had a high-level manager that called frequent meetings. His real need was status updates on various processes, so 50 of us would sit in a room while he asked each one of us questions. He believed this larger meeting helped us "cross pollinate ideas". In fact, it was a complete waste of time for most everyone, except in the one or two moments that they interacted with him. So I wrote some code for a Palm Pilot (which was a kind of SmartPhone but with no phone and no real graphics, but this was in the days when we had just discovered fire and the wheel, although the order of those things is still in debate) that took an average of the salaries of the people in the room (I guessed at it) and ran a timer which multiplied the number of people against the salaries. I left that running in plain sight for him, and when he asked about it, I explained how much the meetings were really costing the company. We had far fewer meetings after. Meetings are now web-enabled. I believe that's largely a good thing, since it saves on travel time and allows more people to participate, but I think the rule above still holds. And in fact, there are some other rules that you should follow to have a great meeting - and fewer of them. Be Clear About the Goal This is important in any meeting, but all of us have probably gotten an invite with a web link and an ambiguous title. Then you get to the meeting, and it's a 500-level deep-dive on something everyone expects you to know. This is unfair to the "expert" and to the participants. I always tell people that invite me to a meeting that I will be as detailed as I can - but the more detail they can tell me about the questions, the more detailed I can be in my responses. Granted, there are times when you don't know what you don't know, but the more you can say about the topic the better. There's another point here - and it's that you should have a clearly defined "win" for the meeting. When the meeting is over, and everyone goes back to work, what were you expecting them to do with the information? Have that clearly defined in your head, and in the meeting invite. Understand the Technology There are several web-meeting clients out there. I use them all, since I meet with clients all over the world. They all work differently - so I take a few moments and read up on the different clients and find out how I can use the tools properly. I do this with the technology I use for everything else, and it's important to understand it if the meeting is to be a success. If you're running the meeting, know the tools. I don't care if you like the tools or not, learn them anyway. Don't waste everyone else's time just because you're too bitter/snarky/lazy to spend a few minutes reading. Check your phone or mic. Check your video size. Install (and learn to use)  ZoomIT (http://technet.microsoft.com/en-us/sysinternals/bb897434.aspx). Format your slides or screen or output correctly. Learn to use the voting features of the meeting software, and especially it's whiteboard features. Figure out how multiple monitors work. Try a quick meeting with someone to test all this. Do this *before* you invite lots of other people to your meeting.   Use a WebCam I'm not a pretty man. I have a face fit for radio. But after attending a meeting with clients where one Microsoft person used a webcam and another did not, I'm convinced that people pay more attention when a face is involved. There are tons of studies around this, or you can take my word for it, but toss a shirt on over those pajamas and turn the webcam on. Set Up Early Whether you're attending or leading the meeting, don't wait to sign on to the meeting at the time when it starts. I can almost plan that a 10:00 meeting will actually start at 10:10 because the participants/leader is just now installing the web client for the meeting at 10:00. Sign on early, go on mute, and then wait for everyone to arrive. Mute When Not Talking No one wants to hear your screaming offspring / yappy dog / other cubicle conversations / car wind noise (are you driving in a desert storm or something?) while the person leading the meeting is trying to talk. I use the Lync software from Microsoft for my meetings, and I mute everyone by default, and then tell them to un-mute to talk to the group. Share Collateral If you have a PowerPoint deck, mail it out in case you have a tech failure. If you have a document, share it as an attachment to the meeting. Don't make people ask you for the information - that's why you're there to begin with. Even better, send it out early. "But", you say, "then no one will come to the meeting if they have the deck first!" Uhm, then don't have a meeting. Send out the deck and a quick e-mail and let everyone get on with their productive day. Set Actions At the Meeting A meeting should have some sort of outcome (see point one). That means there are actions to take, a follow up, or some deliverable. Otherwise, it's an e-mail. At the meeting, decide who will do what, when things are needed, and so on. And avoid, if at all possible, setting up another meeting, unless absolutely necessary. So there you have it. Whether it's on-premises or on the web, meetings are a necessary evil, and should be treated that way. Like politicians, you should have as few of them as are necessary to keep the roads paved and public libraries open.

  • Secure Your Wireless Router: 8 Things You Can Do Right Now

    - by Chris Hoffman
    A security researcher recently discovered a backdoor in many D-Link routers, allowing anyone to access the router without knowing the username or password. This isn’t the first router security issue and won’t be the last. To protect yourself, you should ensure that your router is configured securely. This is about more than just enabling Wi-Fi encryption and not hosting an open Wi-Fi network. Disable Remote Access Routers offer a web interface, allowing you to configure them through a browser. The router runs a web server and makes this web page available when you’re on the router’s local network. However, most routers offer a “remote access” feature that allows you to access this web interface from anywhere in the world. Even if you set a username and password, if you have a D-Link router affected by this vulnerability, anyone would be able to log in without any credentials. If you have remote access disabled, you’d be safe from people remotely accessing your router and tampering with it. To do this, open your router’s web interface and look for the “Remote Access,” “Remote Administration,” or “Remote Management” feature. Ensure it’s disabled — it should be disabled by default on most routers, but it’s good to check. Update the Firmware Like our operating systems, web browsers, and every other piece of software we use, router software isn’t perfect. The router’s firmware — essentially the software running on the router — may have security flaws. Router manufacturers may release firmware updates that fix such security holes, although they quickly discontinue support for most routers and move on to the next models. Unfortunately, most routers don’t have an auto-update feature like Windows and our web browsers do — you have to check your router manufacturer’s website for a firmware update and install it manually via the router’s web interface. Check to be sure your router has the latest available firmware installed. Change Default Login Credentials Many routers have default login credentials that are fairly obvious, such as the password “admin”. If someone gained access to your router’s web interface through some sort of vulnerability or just by logging onto your Wi-Fi network, it would be easy to log in and tamper with the router’s settings. To avoid this, change the router’s password to a non-default password that an attacker couldn’t easily guess. Some routers even allow you to change the username you use to log into your router. Lock Down Wi-Fi Access If someone gains access to your Wi-Fi network, they could attempt to tamper with your router — or just do other bad things like snoop on your local file shares or use your connection to downloaded copyrighted content and get you in trouble. Running an open Wi-Fi network can be dangerous. To prevent this, ensure your router’s Wi-Fi is secure. This is pretty simple: Set it to use WPA2 encryption and use a reasonably secure passphrase. Don’t use the weaker WEP encryption or set an obvious passphrase like “password”. Disable UPnP A variety of UPnP flaws have been found in consumer routers. Tens of millions of consumer routers respond to UPnP requests from the Internet, allowing attackers on the Internet to remotely configure your router. Flash applets in your browser could use UPnP to open ports, making your computer more vulnerable. UPnP is fairly insecure for a variety of reasons. To avoid UPnP-based problems, disable UPnP on your router via its web interface. If you use software that needs ports forwarded — such as a BitTorrent client, game server, or communications program — you’ll have to forward ports on your router without relying on UPnP. Log Out of the Router’s Web Interface When You’re Done Configuring It Cross site scripting (XSS) flaws have been found in some routers. A router with such an XSS flaw could be controlled by a malicious web page, allowing the web page to configure settings while you’re logged in. If your router is using its default username and password, it would be easy for the malicious web page to gain access. Even if you changed your router’s password, it would be theoretically possible for a website to use your logged-in session to access your router and modify its settings. To prevent this, just log out of your router when you’re done configuring it — if you can’t do that, you may want to clear your browser cookies. This isn’t something to be too paranoid about, but logging out of your router when you’re done using it is a quick and easy thing to do. Change the Router’s Local IP Address If you’re really paranoid, you may be able to change your router’s local IP address. For example, if its default address is 192.168.0.1, you could change it to 192.168.0.150. If the router itself were vulnerable and some sort of malicious script in your web browser attempted to exploit a cross site scripting vulnerability, accessing known-vulnerable routers at their local IP address and tampering with them, the attack would fail. This step isn’t completely necessary, especially since it wouldn’t protect against local attackers — if someone were on your network or software was running on your PC, they’d be able to determine your router’s IP address and connect to it. Install Third-Party Firmwares If you’re really worried about security, you could also install a third-party firmware such as DD-WRT or OpenWRT. You won’t find obscure back doors added by the router’s manufacturer in these alternative firmwares. Consumer routers are shaping up to be a perfect storm of security problems — they’re not automatically updated with new security patches, they’re connected directly to the Internet, manufacturers quickly stop supporting them, and many consumer routers seem to be full of bad code that leads to UPnP exploits and easy-to-exploit backdoors. It’s smart to take some basic precautions. Image Credit: Nuscreen on Flickr

  • Silverlight 4 Released

    - by ScottGu
    The final release of Silverlight 4 is now available. What is in the Silverlight 4 Release Silverlight 4 contains a ton of new features and capabilities.  In particular we focused on three scenarios with this release: Further enhancing media support Building great business applications Enabling out of the browser experiences On Tuesday I gave a 60 minute keynote about Silverlight 4 which showed off many of the new features and capabilities now available.  You can watch my keynote to learn more about Silverlight 4 and see a ton of great demos of it in action. Also check out these three great posts by Tim Heuer that talk about the new features and provide a guide to the new Silverlight 4 capabilities: Silverlight 4 Beta – A Guide to the New Features Silverlight 4 RC – What was updated Silverlight 4 Released Also read David Anson’s great Silverlight 4 Toolkit post to learn more about the new controls and functionality also available within the Silverlight Toolkit release we also made available today.  Also visit this page to learn more about the new Pivot functionality in Silverlight 4 – which makes it really easy to visualize and interact with collections of images using Silverlight. Lastly – make sure to visit the www.silverlight.net web-site and visit the “Get Started” section to find free tutorials that you can use. Download and Install Silverlight 4 Tools for VS 2010 To develop Silverlight 4 applications you should first download and install Visual Studio 2010 or download and install the free Visual Web Developer 2010 Express edition. Then install the Silverlight Tools RC2 for Visual Studio 2010.  This setup includes the Silverlight 4 Developer Runtime, Silverlight 4 SDK, RIA Services, and VS 2010 tools support.  Once installed you can do File->New Project and choose Silverlight Application to create your first Silverlight 4 project.  You can then use the new WYSIWYG Silverlight designer in Visual Studio 2010 to design and build rich Silverlight 4 applications. Important: If you previously installed the Silverlight 4 Beta or RC build on your machine, please make sure to go into Add/Remove programs and uninstall the “Update for Visual Studio 2010 (KB976272)” package prior to installing the Silverlight Tools RC2 for Visual Studio 2010 setup.  Note that while Silverlight 4 is released, the “Silverlight 4 Tools for VS 2010” is currently in “RC2” mode (meaning we are going to keep an eye out for any remaining issues before finally calling it done).  We’ll update the tools to be “final” in a few weeks once we verify that no last minute issues/bugs remain. Download and Install Expression Blend 4 Release Candidate You can also download and install the Expression Blend 4 RC to create and design great Silverlight 4 applications.  Blend contains “Sketchflow” support – which makes it really easy to rapidly prototype ideas and applications.  To learn more about Sketchflow watch this 90 second video of it in action. Summary Today’s release is the fourth release of Silverlight that we’ve shipped in the last 2.5 years.  The team has done a great job of advancing it quickly and staying focused.  We think today’s Silverlight 4 release opens up a ton of new opportunities to build great solutions for both consumers and business scenarios.  We are looking forward to seeing what you build with it! Hope this helps, Scott

  • Cocos2d-xna memory management for WP8

    - by Arkiliknam
    I recently upgraded to VS2012 and try my in dev game out on the new WP8 emulators but was dismayed to find out the emulator now crashes and throws an out of memory exception during my sprite loading procedure (funnily, it still works in WP7 emulators and on my WP7). Regardless of whether the problem is the emulator or not, I want to get a clear understanding of how I should be managing memory in the game. My game consists of a character whom has 4 or more different animations. Each animation consists of 4 to 7 frames. On top of that, the character has up to 8 stackable visualization modifications (eg eye type, nose type, hair type, clothes type). Pre memory issue, I preloaded all textures for each animation frame and customization and created animate action out of them. The game then plays animations using the customizations applied to that current character. I re-looked at this implementation when I received the out of memory exceptions and have started playing with RenderTexture instead, so instead of pre loading all possible textures, it on loads textures needed for the character, renders them onto a single texture, from which the animation is built. This means the animations use 1/8th of the sprites they were before. I thought this would solve my issue, but it hasn't. Here's a snippet of my code: var characterTexture = CCRenderTexture.Create((int)width, (int)height); characterTexture.BeginWithClear(0, 0, 0, 0); // stamp a body onto my texture var bodySprite = MethodToCreateSpecificSprite(); bodySprite.Position = centerPoint; bodySprite.Visit(); bodySprite.Cleanup(); bodySprite = null; // stamp eyes, nose, mouth, clothes, etc... characterTexture.End(); As you can see, I'm calling CleanUp and setting the sprite to null in the hope of releasing the memory, though I don't believe this is the right way, nor does it seem to work... I also tried using SharedTextureCache to load textures before Stamping my texture out, and then clearing the SharedTextureCache with: CCTextureCache.SharedTextureCache.RemoveAllTextures(); But this didn't have an effect either. Any tips on what I'm not doing? I used VS to do a memory profile of the emulation causing the crash. Both WP7.1 and WP8 emulators peak at about 150mb of usage. WP8 crashes and throws an out of memory exception. Each customisation/frame is 15kb at the most. Lets say there are 8 layers of customisation = 120kb but I render then onto one texture which I would assume is only 15kb again. Each animation is 8 frames at the most. That's 15kb for 1 texture, or 960kb for 8 textures of customisation. There are 4 animation sets. That's 60Kb for 4 sets of 1 texture, or 3.75MB for 4 sets of 8 textures of customisation. So even if its storing every layer, its 3.75MB.... no where near the 150mb breaking point my profiler seems to suggest :( WP 7.1 Memory Profile (max 150MB) WP8 Memory Profile (max 150MB and crashes)

  • This Week in Geek History: Gmail Goes Public, Deep Blue Wins at Chess, and the Birth of Thomas Edison

    - by Jason Fitzpatrick
    Every week we bring you a snapshot of the week in Geek History. This week we’re taking a peek at the public release of Gmail, the first time a computer won against a chess champion, and the birth of prolific inventor Thomas Edison. Gmail Goes Public It’s hard to believe that Gmail has only been around for seven years and that for the first three years of its life it was invite only. In 2007 Gmail dropped the invite only requirement (although they would hold onto the “beta” tag for another two years) and opened its doors for anyone to grab a username @gmail. For what seemed like an entire epoch in internet history Gmail had the slickest web-based email around with constant innovations and features rolling out from Gmail Labs. Only in the last year or so have major overhauls at competitors like Hotmail and Yahoo! Mail brought other services up to speed. Can’t stand reading a Week in Geek History entry without a random fact? Here you go: gmail.com was originally owned by the Garfield franchise and ran a service that delivered Garfield comics to your email inbox. No, we’re not kidding. Deep Blue Proves Itself a Chess Master Deep Blue was a super computer constructed by IBM with the sole purpose of winning chess matches. In 2011 with the all seeing eye of Google and the amazing computational abilities of engines like Wolfram Alpha we simply take powerful computers immersed in our daily lives for granted. The 1996 match against reigning world chest champion Garry Kasparov where in Deep Blue held its own, but ultimately lost, in a  4-2 match shook a lot of people up. What did it mean if something that was considered such an elegant and quintessentially human endeavor such as chess was so easy for a machine? A series of upgrades helped Deep Blue outright win a match against Kasparov in 1997 (seen in the photo above). After the win Deep Blue was retired and disassembled. Parts of Deep Blue are housed in the National Museum of History and the Computer History Museum. Birth of Thomas Edison Thomas Alva Edison was one of the most prolific inventors in history and holds an astounding 1,093 US Patents. He is responsible for outright inventing or greatly refining major innovations in the history of world culture including the phonograph, the movie camera, the carbon microphone used in nearly every telephone well into the 1980s, batteries for electric cars (a notion we’d take over a century to take seriously), voting machines, and of course his enormous contribution to electric distribution systems. Despite the role of scientist and inventor being largely unglamorous, Thomas Edison and his tumultuous relationship with fellow inventor Nikola Tesla have been fodder for everything from books, to comics, to movies, and video games. Other Notable Moments from This Week in Geek History Although we only shine the spotlight on three interesting facts a week in our Geek History column, that doesn’t mean we don’t have space to highlight a few more in passing. This week in Geek History: 1971 – Apollo 14 returns to Earth after third Lunar mission. 1974 – Birth of Robot Chicken creator Seth Green. 1986 – Death of Dune creator Frank Herbert. Goodnight Dune. 1997 – Simpsons becomes longest running animated show on television. Have an interesting bit of geek trivia to share?

  • What is Agile Modeling and why do I need it?

    What is Agile Modeling and why do I need it? Agile Modeling is an add-on to existing agile methodologies like Extreme programming (XP) and Rational Unified Process (RUP). Agile Modeling enables developers to develop a customized software development process that actually meets their current development needs and is flexible enough to adjust in the future. According to Scott Ambler, Agile Modeling consists of five core values that enable this methodology to be effective and light weight Agile Modeling Core Values: Communication Simplicity Feedback Courage Humility Communication is a key component to any successful project. Open communication between stakeholder and the development team is essential when developing new applications or maintaining legacy systems. Agile models promote communication amongst software development teams and stakeholders. Furthermore, Agile Models provide a common understanding of an application for members of a software development team allowing them to have a universal common point of reference. The use of simplicity in Agile Models enables the exploration of new ideas and concepts through the use of basic diagrams instead of investing the time in writing tens or hundreds of lines of code. Feedback in regards to application development is essential. Feedback allows a development team to confirm that the development path is on track. Agile Models allow for quick feedback from shareholders because minimal to no technical expertise is required to understand basic models. Courage is important because you need to make important decisions and be able to change direction by either discarding or refactoring your work when some of your decisions prove inadequate, according to Scott Ambler. As a member of a development team, we must admit that we do not know everything even though some of us think we do. This is where humility comes in to play. Everyone is a knowledge expert in their own specific domain. If you need help with your finances then you would consult an accountant. If you have a problem or are in need of help with a topic why would someone not consult with a subject expert? An effective approach is to assume that everyone involved with your project has equal value and therefore should be treated with respect. Agile Model Characteristics: Purposeful Understandable Sufficiently Accurate Sufficiently Consistent Sufficiently Detailed Provide Positive Value Simple as Possible Just Fulfill Basic Requirements According to Scott Ambler, Agile models are the most effective possible because the time that is invested in the model is just enough effort to complete the job. Furthermore, if a model isn’t good enough yet then additional effort can be invested to get more value out of the model. However if a model is good enough, for the current needs, or surpass the current needs, then any additional work done on the model would be a waste. It is important to remember that good enough is in the eye of the beholder, so this can be tough. In order for Agile Models to work effectively Active Stakeholder need to participation in the modeling process. Finally it is also very important to model with others, this allows for additionally input ensuring that all the shareholders needs are reflected in the models. How can Agile Models be incorporated in to our projects? Agile Models can be incorporated in to our project during the requirement gathering and design phases. As requirements are gathered the models should be updated to incorporate the new project details as they are defined and updated. Additionally, the Agile Models created during the requirement phase can be the bases for the models created during the design phase.  It is important to only add to the model when the changes fit within the agile model characteristics and they do not over complicate the design.

  • BI and EPM Landscape

    - by frank.buytendijk
    Most of my blog entries are not about Oracle products, and most of the latest entries are about topics such as IT strategy and enterprise architecture. However, given my background at Gartner, and at Hyperion, I still keep a close eye on what's happening in BI and EPM. One important reason is that I believe there is significant competitive value for organizations getting BI and EPM right. Davenport and Harris wrote a great book called "Competing on Analytics", in which they explain this in a very engaging and convincing way. At Oracle we have defined the concept of "management excellence" that outlines what organizations have to do to keep or create a competitive edge. It's not only in the business processes, but also in the management processes. Recently, Gartner published its 2009 market shares report for BI, Analytics, and Performance Management. Gartner identifies the same three segments that Oracle does: (1) CPM Suites (Oracle refers not to Corporate Performance Management, but Enterprise Performance Management), (2) BI Platform, and (3) Analytic Applications & Performance Management. According to Gartner, Oracle's share is increasing with revenue growing by more than 5%. Oracle currently holds the #2 market share position in the overall BI Software space based on total BI software revenue. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 Gartner has ranked Oracle as #1 in the CPM Suites worldwide sub-segment based on total BI software revenue, and Oracle is gaining share with revenue growing by more than 6% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 The Analytic Applications & Performance Management subsegment is more fragmented. It has for instance a very large "Other Vendors" category. The largest player traditionally is SAS. Analytic Applications are often meant for very specific analytic needs in very specific industry sectors. According to Gartner, from the large vendors, again Oracle is the one who is gaining the most share - with total BI software revenue growth close to 15% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 I believe this shows Oracle's integration strategy is working. In fact, integration actually is the innovation. BI and EPM have been silo technology platforms and application suites way too long. Management and measuring performance should be very closely linked to strategy execution, which is the domain of other business application areas such as CRM, ERP, and Supply Chain. BI and EPM are not about "making better decisions" anymore, but are part of a tangible action framework. Furthermore, organizations are getting more serious about ecosystem thinking. They do not evaluate single tools anymore for different application areas, but buy into a complete ecosystem of hardware, software and services. The best ecosystem is the one that offers the most options, in environments where the uncertainty is high and investments are hard to reverse. The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them "upperware". Many are active in the BI and EPM space. Big players can offer a lot, but there are always many areas that are covered by specialty vendors. Oracle openly embraces those technologies within the ecosystem as well. Complete, open and integrated still accurately describes the Oracle product strategy. frank

  • SharePoint OCR image files indexing

    Introduction This article describes how to setup indexing of the image files (including TIFF, PDF, JPEG, BMP...) using OCR technology. The indexing described below utilizes Microsoft IFilter technology and as such is not specific to SharePoint, but can be used with any product that uses Microsoft indexing: Microsoft Search, Desktop search, SQL Server search, and through the plug-ins with Google desktop search. I however use it with Microsoft Windows SharePoint Services 2003. For those other products, the registration may need to be slightly different. Background  One of the projects I was working on required a storage of old documents scanned into PDF files. Then there was a separate team of people responsible for providing a tags for a search engine so those image documents could be found. The whole process was clumsy, labor intensive, and error prone. That was what started me on my exploration path. OCR The first search I fired was for the Open Source OCR products. Pretty quickly, I narrowed it down to TESSERACT (http://code.google.com/p/tesseract-ocr/). Tesseract is an orphaned brain child of HP that worked on it from 1985 to 1995. Then it was moved to the Open Source, and now if I understand it correctly, Google is working on it. With credentials like that, it's no wonder that Tesseract scores one of the highest marks on OCR recognition and accuracy. After downloading and struggling just a bit, I got Tesseract to work. The struggling part was that the home page claims that its base input format is a TIFF file. May be my TIFFs were bad, but I was able to get it to work only for BMP files. Image files conversion So now that I have an OCR that can convert BMP files into text, how do I get text out of the image PDF files? One more search, and I settled down on ImageMagic (http://www.imagemagick.org/). This is another wonderful Open Source utility that can convert any file into image. It did work out of the box, converting any TIFF files into bitmaps, but to get PDF files converted, it requires a GhostScript (http://mirror.cs.wisc.edu/pub/mirrors/ghost/GPL/gs864/gs864w32.exe). Dealing with text PDFs With that utility installed, I was cooking - I can convert any file (in particular PDF and TIFF) into bitmap, and then I can extract the text out of the bitmap. The only consideration was to somehow treat PDF files containing text differently - after all, OCR is very computation intensive and somewhat error prone even with perfect image quality and resolution. So another quick search, and I have a PDFTOTEXT (ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.02pl4-win32.zip) - thank God for Open Source! With these guys, I can pull text out of PDF in an eye blink. However, I would get nothing for pure image PDFs, but I already have a solution for that! Batch process It took another 15 minutes to setup a batch script to automate the process: Check the file extension If file is a PDF file try to extract text out of it if there is more than certain amount of text in the file - done! if there is no text, convert first page into bitmap run OCR on the bitmap For any other file type, convert file into bitmap Run OCR on the bitmap Once you unzip the attached project, check out the bin\OCR.BAT file. It will create a temporary file in the directory where your source file is with the same name + the '.txt' extension.Continue span.fullpost {display:none;}

  • SQLAuthority News – Android Efficiency Tips and Tricks – Personal Technology Tip #003

    - by pinaldave
    I use my phone for lots of things.  I use it mainly to replace my tablet – I can e-mail, take and edit photos, and do almost everything I can do on a laptop with this phone.  And I am sure that there are many of you out there just like me.  I personally have a Galaxy S3, which uses the Android operating system, and I have decided to feature it as the third installment of my Technology Tips and Tricks series. 1) Shortcut to your favorite contacts on home screen Access your most-called contacts easily from your home screen by holding your finger on any empty spot on the home screen.  A menu will pop up that allows you to choose Shortcuts, and Contact.  You can scroll through your contact list and then just tap on the name of the person you want to be able to dial with a single click. 2) Keep track of your data usage Yes, we all should keep a close eye on our data usage, because it is very easy to go over our limits and then end up with a giant bill at the end of the month.  Never get surprised when you open that mobile phone envelope again.  Go to Settings, then Data Usage, and you can find a quick rundown of your usage, how much data each app uses, and you can even set alarms to let you know when you are nearing the limits.   Better yet, you can set the phone to stop using data when it reaches a certain limit. 3) Bring back Good Grammar We often hear proclamations about the downfall of written language, and how texting abbreviations, misspellings, and lack of punctuation are the root of all evil.  Well, we can show all those doomsdayers that all is not lost by bringing punctuation back to texting.  Usually we leave it off when we text because it takes too long to get to the screen with all the punctuation options.  But now you can hold down the period (or “full stop”) button and a list of all the commonly-used punctuation marks will pop right up. 4) Apps, Apps, Apps and Apps And finally, I cannot end an article about smart phones without including a list of my favorite apps.  Here are a list of my Top 10 Applications on my Android (not counting social media apps). Advanced Task Killer – Keeps my phone snappy by closing un-necessary apps WhatsApp - my favorite alternate to Text SMS Flipboard - my ‘timepass’ moments Skype – keeps me close to friends and family GoogleMaps - I am never lost because of this one thing Amazon Kindle – Books my best friends DropBox - My data always safe Pluralsight Player – Learning never stops for me Samsung Kies Air – Connecting Phone to Computer Chrome – Replacing default browser I have not included any social media applications in the above list, but you can be sure that I am linked to Twitter, Facebook, Google+, LinkedIn, and YouTube.

  • Observations From The Corner of a Starbucks

    - by Chris Williams
    I’ve spent the last 3 days sitting in a Starbucks for 4-8 hours at a time. As a result, I’ve observed a lot of interesting behavior and people (most of whom were uninteresting themselves.) One of the things I’ve noticed is that most people don’t sit down. They come in, get their drink and go. The ones that do sit down, stay much longer than it takes to consume their drink. The drink is just an incidental purchase. Certainly not the reason they are here. Most of the people who sit also have laptops. Probably around 75%. Only a few have kids (with them) but the ones that do, have very small kids. Toddlers or younger. Of all the “campers” only a small percentage are wearing headphone, presumably because A) external noise doesn’t bother them or B) they aren’t working on anything important. My buddy George falls into category A, but he grew up in a house full of people. Silence freaks him out far more than noise. My brother and I, on the other hand, were both only children and don’t handle noisy distractions well. He needs it quiet (like a tomb) and I need music. Go figure… I can listen to Britney Spears mixed with Apoptygma Berzerk and Anthrax and crank out 30 pages, but if your toddler is banging his spoon on the table, you’re getting a dirty look… unless I have music, then all is right with the world. Anyway, enough about me. Most of the people who come in as a group are smiling when they enter. Half as many are smiling when they leave. People who come in alone typically aren’t smiling at all. The average age, over the last three days seems to be early 30s… with a couple of senior citizens and teenagers at either end of the curve. The teenagers almost never stay. They have better stuff to do on a nice day. The senior citizens are split nearly evenly between campers and in&outs. Most of the non-solo campers have 1 person with a laptop, while the other reads the paper or a book. Some campers bring multiple laptops… but only really look at one of them. This Starbucks has a drive through. The line is almost never more than 2-3 cars long but apparently a lot of the in&out people would rather come in and stand in line behind (up to) 5 people. The music in here sucks. My musical tastes can best be described as eclectic to bad, but I can still get work done (see above.) I find the music in this particular Starbucks to be discordant and jarring. At this Starbucks, the coffee lingo is apparently something that is meant to occur between employees only. The nice lady at the counter can handle orders in plain English and translate them to Baristaspeak (Baristese?) quite efficiently. If you order in Baristaspeak however, she will look confused and repeat your order back to you in plain English to confirm you actually meant what you said. Then she will say it in Baristaspeak to the lady making your drink. Nobody in this Starbucks (other than the Baristas) makes eye-contact… at least not with me. Of course that may be indicative of a separate issue. ;)

  • What’s the use of code reuse?

    - by Tony Davis
    All great developers write reusable code, don’t they? Well, maybe, but as with all statements regarding what “great” developers do or don’t do, it’s probably an over-simplification. A novice programmer, in particular, will encounter in the literature a general assumption of the importance of code reusability. They spend time worrying about DRY (don’t repeat yourself), moving logic into specific “helper” modules that they can then reuse, agonizing about the minutiae of the class structure, inheritance and interface design that will promote easy reuse. Unfortunately, writing code specifically for reuse often leads to complicated object hierarchies and inheritance models that are anything but reusable. If, instead, one strives to write simple code units that are highly maintainable and perform a single function, in a concise, isolated fashion then the potential for reuse simply “drops out” as a natural by-product. Programmers, of course, care about these principles, about encapsulation and clean interfaces that don’t expose inner workings and allow easy pluggability. This is great when it helps with the maintenance and development of code but how often, in practice, do we actually reuse our code? Most DBAs and database developers are familiar with the practical reasons for the limited opportunities to reuse database code and its potential downsides. However, surely elsewhere in our code base, reuse happens often. After all, we can all name examples, such as date/time handling modules, which if we write with enough care we can plug in to many places. I spoke to a developer just yesterday who looked me in the eye and told me that in 30+ years as a developer (a successful one, I’d add), he’d never once reused his own code. As I sat blinking in disbelief, he explained that, of course, he always thought he would reuse it. He’d often agonized over its design, certain that he was creating code of great significance that he and other generations would reuse, with grateful tears misting their eyes. In fact, it never happened. He had in his head, most of the algorithms he needed and would simply write the code from scratch each time, refining the algorithms and tailoring the code to meet the specific requirements. It was, he said, simply quicker to do that than dig out the old code, check it, correct the mistakes, and adapt it. Is this a common experience, or just a strange anomaly? Viewed in a certain light, building code with a focus on reusability seems to hark to a past age where people built cars and music systems with the idea that someone else could and would replace and reuse the parts. Technology advances so rapidly that the next time you need the “same” code, it’s likely a new technique, or a whole new language, has emerged in the meantime, better equipped to tackle the task. Maybe we should be less fearful of the idea that we could write code well suited to the system requirements, but with little regard for reuse potential, and then rewrite a better version from scratch the next time.

  • The Evolution Of C#

    - by Paulo Morgado
    The first release of C# (C# 1.0) was all about building a new language for managed code that appealed, mostly, to C++ and Java programmers. The second release (C# 2.0) was mostly about adding what wasn’t time to built into the 1.0 release. The main feature for this release was Generics. The third release (C# 3.0) was all about reducing the impedance mismatch between general purpose programming languages and databases. To achieve this goal, several functional programming features were added to the language and LINQ was born. Going forward, new trends are showing up in the industry and modern programming languages need to be more: Declarative With imperative languages, although having the eye on the what, programs need to focus on the how. This leads to over specification of the solution to the problem in hand, making next to impossible to the execution engine to be smart about the execution of the program and optimize it to run it more efficiently (given the hardware available, for example). Declarative languages, on the other hand, focus only on the what and leave the how to the execution engine. LINQ made C# more declarative by using higher level constructs like orderby and group by that give the execution engine a much better chance of optimizing the execution (by parallelizing it, for example). Concurrent Concurrency is hard and needs to be thought about and it’s very hard to shoehorn it into a programming language. Parallel.For (from the parallel extensions) looks like a parallel for because enough expressiveness has been built into C# 3.0 to allow this without having to commit to specific language syntax. Dynamic There was been lots of debate on which ones are the better programming languages: static or dynamic. The fact is that both have good qualities and users of both types of languages want to have it all. All these trends require a paradigm switch. C# is, in many ways, already a multi-paradigm language. It’s still very object oriented (class oriented as some might say) but it can be argued that C# 3.0 has become a functional programming language because it has all the cornerstones of what a functional programming language needs. Moving forward, will have even more. Besides the influence of these trends, there was a decision of co-evolution of the C# and Visual Basic programming languages. Since its inception, there was been some effort to position C# and Visual Basic against each other and to try to explain what should be done with each language or what kind of programmers use one or the other. Each language should be chosen based on the past experience and familiarity of the developer/team/project/company and not by particular features. In the past, every time a feature was added to one language, the users of the other wanted that feature too. Going forward, when a feature is added to one language, the other will work hard to add the same feature. This doesn’t mean that XML literals will be added to C# (because almost the same can be achieved with LINQ To XML), but Visual Basic will have auto-implemented properties. Most of these features require or are built on top of features of the .NET Framework and, the focus for C# 4.0 was on dynamic programming. Not just dynamic types but being able to talk with anything that isn’t a .NET class. Also introduced in C# 4.0 is co-variance and contra-variance for generic interfaces and delegates. Stay tuned for more on the new C# 4.0 features.

  • F# WPF Form &ndash; the basics

    - by MarkPearl
    I was listening to Dot Net Rocks show #560 about F# and during the podcast Richard Campbell brought up a good point with regards to F# and a GUI. In essence what I understood his point to be was that until one could write an end to end application in F#, it would be a hard sell to developers to take it on. In part I agree with him, while I am beginning to really enjoy learning F#, I can’t but help feel that I would be a lot further into the language if I could do my Windows Forms like I do in C# or VB.NET for the simple reason that in “playing” applications I spend the majority of the time in the UI layer… So I have been keeping my eye out for some examples of creating a WPF form in a F# project and came across Tim’s F# Twitter Stream Sample, which had exactly this…. of course he actually had a bit more than a basic form… but it was enough for me to scrap the insides and glean what I needed. So today I am going to make just the very basic WPF form with all the goodness of a XAML window. Getting Started First thing we need to do is create a new solution with a blank F# application project – I have made mine called FSharpWPF. Once you have the project created you will need to change the project type from a Console Application to a Windows Application. You do this by right clicking on the project file and going to its properties… Once that is done you will need to add the appropriate references. You do this by right clicking on the References in the Solution Explorer and clicking “Add Reference'”. You should add the appropriate .Net references below for WPF & XAMl to work. Once these references are added you then need to add your XAML file to the project. You can do this by adding a new item to the project of type xml and simply changing the file extension from xml to xaml. Once the xaml file has been added to the project you will need to add valid window XAML. Example of a very basic xaml file is shown below… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF WPF Form" Height="350" Width="525"> <Grid> </Grid> </Window> Once your xaml file is done… you need to set the build action of the xaml file from “None” to “Resource” as depicted in the picture below. If you do not set this you will get an IOException error when running the completed project with a message along the lines of “Cannot locate resource ‘window.xaml’ You then need to tie everything up by putting the correct F# code in the Program.fs to load the xaml window. In the Program.fs put the following code… module Program open System open System.Collections.ObjectModel open System.IO open System.Windows open System.Windows.Controls open System.Windows.Markup [<STAThread>] [<EntryPoint>] let main(_) = let w = Application.LoadComponent(new System.Uri("/FSharpWPF;component/Window.xaml", System.UriKind.Relative)) :?> Window (new Application()).Run(w) Once all this is done you should be able to build and run your project. What you have done is created a WPF based window inside a FSharp project. It should look something like below…   Nothing to exciting, but sufficient to illustrate the very basic WPF form in F#. Hopefully in future posts I will build on this to expose button events etc.

  • Monitoring the Application alongside SQL Server

    - by Tony Davis
    Sometimes, on Simple-Talk, it takes a while to spot strange and unexpected patterns of user activity, or small bugs. For example, one morning we spotted that an article’s comment count had leapt to 1485, but that only four were displayed. With some rooting around in Google Analytics, and the endlessly annoying Community Server admin-interface, we were able to work out that a few days previously the article had been subject to a spam attack and that the comment count was for some reason including both accepted and unaccepted comments (which in turn uncovered a bug in the SQL). This sort of incident made us a lot keener on monitoring Simple-talk website usage more effectively. However, the metrics we wanted are troublesome, because they are far too specific for Google Analytics to measure, and the SQL Server backend doesn’t keep sufficient information to enable us to plot trends. The latter could provide, for example, the total number of comments made on, or votes cast for, articles, over all time, but not the number that occur by hour over a set time. We lacked a baseline, in other words. We couldn’t alter the database, as it is a bought-in package. We had neither the resources nor inclination to build-in dedicated application monitoring. Possibly, we could investigate a third-party tool to do the job; but then it occurred to us that we were already using a monitoring tool (SQL Monitor) to keep an eye on the database. It stored data, made graphs and sent alerts. Could we get it to monitor some aspects of the application as well? Of course, SQL Monitor’s single purpose is to check and monitor SQL Server, over time, rather than to monitor applications that use SQL Server. However, how different is the business of gathering and plotting SQL Server Wait Stats, from gathering and plotting various aspects of user activity on the site? Not a lot, it turns out. The latest version allows us to write our own custom monitoring scripts, meaning that we could now monitor any metric in the application that returns an integer. It took little time to write a simple SQL Query that collects basic metrics of the total number of subscribers, votes cast, comments made, or views of articles, over time. The SQL Monitor database polls Simple-Talk every second or so in order to get the latest totals, and can then store and plot this information, or even correlate SQL Server usage to application usage. You can see the live data by visiting monitor.red-gate.com. Click the "Analysis" tab, and select one of the "Simple-talk:" entries in the "Show" box and an appropriate data range (e.g. last 30 days). It’s nascent, and we’re still working on it, but it’s already given us more confidence that we’ll spot quickly trends, bugs, or bursts of ‘abnormal’ activity. If there is a sudden rise in comments, we get an alert, and if it’s due to a spam attack, we can moderate or ban the perpetrator very quickly. We’ve often argued that a tool should perform a single job well rather than turn into a Swiss-army knife, but ironically we’ve rather appreciated being able to make best use of what’s there anyway for a slightly different purpose. Is this a good or common practice? What do you think? Cheers, Tony.

  • Exception Handling Frequency/Log Detail

    - by Cyborgx37
    I am working on a fairly complex .NET application that interacts with another application. Many single-line statements are possible culprits for throwing an Exception and there is often nothing I can do to check the state before executing them to prevent these Exceptions. The question is, based on best practices and seasoned experience, how frequently should I lace my code with try/catch blocks? I've listed three examples below, but I'm open to any advice. I'm really hoping to get some pros/cons of various approaches. I can certainly come up with some of my own (greater log granularity for the O-C approach, better performance for the Monolithic approach), so I'm looking for experience over opinion. EDIT: I should add that this application is a batch program. The only "recovery" necessary in most cases is to log the error, clean up gracefully, and quit. So this could be seen to be as much a question of log granularity as exception handling. In my mind's eye I can imagine good reasons for both, so I'm looking for some general advice to help me find an appropriate balance. Monolitich Approach class Program{ public static void Main(){ try{ Step1(); Step2(); Step3(); } catch (Exception e) { Log(e); } finally { CleanUp(); } } public static void Step1(){ ExternalApp.Dangerous1(); ExternalApp.Dangerous2(); } public static void Step2(){ ExternalApp.Dangerous3(); ExternalApp.Dangerous4(); } public static void Step3(){ ExternalApp.Dangerous5(); ExternalApp.Dangerous6(); } } Delegated Approach class Program{ public static void Main(){ try{ Step1(); Step2(); Step3(); } finally { CleanUp(); } } public static void Step1(){ try{ ExternalApp.Dangerous1(); ExternalApp.Dangerous2(); } catch (Exception e) { Log(e); throw; } } public static void Step2(){ try{ ExternalApp.Dangerous3(); ExternalApp.Dangerous4(); } catch (Exception e) { Log(e); throw; } } public static void Step3(){ try{ ExternalApp.Dangerous5(); ExternalApp.Dangerous6(); } catch (Exception e) { Log(e); throw; } } } Obsessive-Compulsive Approach class Program{ public static void Main(){ try{ Step1(); Step2(); Step3(); } finally { CleanUp(); } } public static void Step1(){ try{ ExternalApp.Dangerous1(); } catch (Exception e) { Log(e); throw; } try{ ExternalApp.Dangerous2(); } catch (Exception e) { Log(e); throw; } } public static void Step2(){ try{ ExternalApp.Dangerous3(); } catch (Exception e) { Log(e); throw; } try{ ExternalApp.Dangerous4(); } catch (Exception e) { Log(e); throw; } } public static void Step3(){ try{ ExternalApp.Dangerous5(); } catch (Exception e) { Log(e); throw; } try{ ExternalApp.Dangerous6(); } catch (Exception e) { Log(e); throw; } } } Other approaches welcomed and encouraged. Above are examples only.

  • Podcast Show Notes: Collaborate 10 Wrap-Up - Part 1

    - by Bob Rhubart
    OK, I know last week I promised you a program featuring Oracle ACE Directors Mike van Alst (IT-Eye) and Jordan Braunstein (TUSC) and The Definitive Guide to SOA: Oracle Service Bus author Jeff Davies. But things happen. In this case, what happened was Collaborate 10 in Las Vegas. Prior to the event I asked Oracle ACE Director and OAUG board member Floyd Teter to see if he could round up a couple of people at the event for an impromtu interview over Skype (I was here in Cleveland) to get their impressions of the event. Listen to Part 1 Floyd, armed with his brand new iPad, went above and beyond the call of duty. At the appointed hour, which turned out to be about hour after the close of Collaborate 10,  Floyd had gathered nine other people to join him in a meeting room somewhere in the Mandalay Bay Convention Center. Here’s the entire roster: Floyd Teter - Project Manager at Jet Propulsion Lab, OAUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Mark Rittman - EMEA Technical Director and Co-Founder, Rittman Mead,  ODTUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Chet Justice - OBI Consultant at BI Wizards Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Elke Phelps - Oracle Applications DBA at Humana, OAUG SIG Chair Blog | LinkedIn | Oracle Mix | Book | Oracle ACE Profile Paul Jackson - Oracle Applications DBA at Humana Blog | LinkedIn | Oracle Mix | Book Srini Chavali - Enterprise Database & Tools Leader at Cummins, Inc Blog | LinkedIn | Oracle Mix Dave Ferguson – President, Oracle Applications Users Group LinkedIn | OAUG Profile John King - Owner, King Training Resources Website | LinkedIn | Oracle Mix Gavyn Whyte - Project Portfolio Manager at iFactory Consulting Blog | Twitter | LinkedIn | Oracle Mix John Nicholson - Channels & Alliances at Greenlight Technologies Website | LinkedIn Big thanks to Floyd for assembling the panelists and handling the on-scene MC/hosting duties.  Listen to Part 1 On a technical note, this discussion was conducted over Skype, using Floyd’s iPad, placed in the middle of the table.  During the call the audio was fantastic – the iPad did a remarkable job. Sadly, the Technology Gods were not smiling on me that day. The audio set-up that I tested successfully before the call failed to deliver when we first connected – I could hear the folks in Vegas, but they couldn’t hear me. A frantic, last-minute adjustment appeared to have fixed that problem, and the audio in my headphones from both sides of the conversation was loud and clear.  It wasn’t until I listened to the playback that I realized that something was wrong. So the audio for Vegas side of the discussion has about the same fidelity as a cell phone. It’s listenable, but disappointing when compared to what it sounded like during the discussion. Still, this was a one shot deal, and the roster of panelists and the resulting conversation was too good and too much fun to scrap just because of an unfortunate technical glitch.   Part 2 of this Collaborate 10 Wrap-Up will run next week. After that, it’s back on track with the previously scheduled program. So stay tuned: RSS del.icio.us Tags: oracle,otn,collborate 10,c10,oracle ace program,archbeat,arch2arch,oaug,odtug,las vegas Technorati Tags: oracle,otn,collborate 10,c10,oracle ace program,archbeat,arch2arch,oaug,odtug,las vegas

  • Archiving SQLHelp tweets

    - by jamiet
    #SQLHelp is a Twitter hashtag that can be used by any Twitter user to get help from the SQL Server community. I think its fair to say that in its first year of being it has proved to be a very useful resource however Kendra Little (@kendra_little) made a very salient point yesterday when she tweeted: Is there a way to search the archives of #sqlhelp Trying to remember answer to a question I know I saw a couple months ago http://twitter.com/#!/Kendra_Little/status/15538234184441856 This highlights an inherent problem with Twitter’s search capability – it simply does not reach far enough back in time. I have made steps to remedy that situation by putting into place two initiatives to archive Tweets that contain the #sqlhelp hashtag. The Archivist http://archivist.visitmix.com/ is a free service that, quite simply, archives a history of tweets that contain a given search term by periodically polling Twitter’s search service with that search term and subsequently displaying a dashboard providing an aggregate view of those tweets for things like tweet volume over time, top users and top words (Archivist FAQ). I have set up an archive on The Archivist for “sqlhelp” which you can view at http://archivist.visitmix.com/jamiet/7. Here is a screenshot of the SQLHelp dashboard 36 minutes after I set it up: There is lots of good information in there, including the fact that Jonathan Kehayias (@SQLSarg) is the most active SQLHelp tweeter (I suspect as an answerer rather than a questioner ) and that SSIS has proven to be a rather (ahem) popular subject!! Datasift The Archivist has its uses though for our purposes it has a couple of downsides. For starters you cannot search through an archive (which is what Kendra was after) and nor can you export the contents of the archive for offline analysis. For those functions we need something a bit more heavyweight and for that I present to you Datasift. Datasift is a tool (currently an alpha release) that allows you to search for tweets and provide them through an object called a Datasift stream. That sounds very similar to normal Twitter search though it has one distinct advantage that other Twitter search tools do not – Datasift has access to Twitter’s Streaming API (aka the Twitter Firehose). In addition it has access to a lot of other rather nice features: It provides the Datasift API that allows you to consume the output of a Datasift stream in your tool of choice (bring on my favourite ultimate mashup tool J ) It has a query language (called Filtered Stream Definition Language – FSDL for short) A Datasift stream can consume (and filter) other Datasift streams Datasift can (and does) consume services other than Twitter If I refer to Datasift as “ETL for tweets” then you may get some sort of idea what it is all about. Just as I did with The Archivist I have set up a publicly available Datasift stream for “sqlhelp” at http://datasift.net/stream/1581/sqlhelp. Here is the FSDL query that provides the data: twitter.text contains "sqlhelp" Pretty simple eh? At the current time it provides little more than a rudimentary dashboard but as Datasift is currently an alpha release I think this may be worth keeping an eye on. The real value though is the ability to consume the output of a stream via Datasift’s RESTful API, observe: http://api.datasift.net/stream.xml?stream_identifier=c7015255f07e982afdeebdf1ae6e3c0d&username=jamiet&api_key=XXXXXXX (Note that an api_key is required during the alpha period so, given that I’m not supplying my api_key, this URI will not work for you) Just to prove that a Datasift stream can indeed consume data from another stream I have set up a second stream that further filters the first one for tweets containing “SSIS”. That one is at http://datasift.net/stream/1586/ssis-sqlhelp and here is the FSDL query: rule "414c9845685ff8d2548999cf3162e897" and (interaction.content contains "ssis") When Datasift moves beyond alpha I’ll re-assess how useful this is going to be and post a follow-up blog. @Jamiet

  • The Oracle Retail Week Awards - most exciting awards yet?

    - by sarah.taylor(at)oracle.com
    Last night's annual Oracle Retail Week Awards saw the UK's top retailers come together to celebrate the very best of our industry over the last year.  The Grosvenor House Hotel on Park Lane in London was the setting for an exciting ceremony which this year marked several significant milestones in British - and global - retail.  Check out our videos about the event at our Oracle Retail YouTube channel, and see if you were snapped by our photographer on our Oracle Retail Facebook page. There were some extremely hot contests for many of this year's awards - and all very deserving winners.  The entries have demonstrated beyond doubt that retailers have striven to push their standards up yet again in all areas over the past year.  The judging panel includes some of the most prestigious names in the retail industry - to impress the panel enough to win an award is a substantial achievement.  This year the panel included the likes of Andy Clarke - Chief Executive of ASDA Group; Mark Newton Jones - CEO of Shop Direct Group; Richard Pennycook - the finance director at Morrisons; Rob Templeman - Chief Executive of Debenhams; and Stephen Sunnucks - the president of Gap Europe.  These are retail veterans  who have each helped to shape the British High Street over the last decade.  It was great to chat with many of them in the Oracle VIP area last night.  For me, last night's highlight was honouring both Sir Stuart Rose and Sir Terry Leahy for their contributions to the retail industry.  Both have set the standards in retailing over the last twenty years and taken their respective businesses from strength to strength, demonstrating that there is always a need for innovation even in larger businesses, and that a business has to adapt quickly to new technology in order to stay competitive.  Sir Terry Leahy's retirement this year marks the end of an era of global expansion for the Tesco group and a milestone in the progression of British retail.  Sir Terry has helped steer Tesco through nearly 20 years of change, with 14 years as Chief Executive.  During this time he led the drive for international expansion and an aggressive campaign to increase market share.  He has led the way for High Street retailers in adapting to the rise of internet retailing and nurtured a very successful home delivery service.  More recently he has pioneered the notion of cross-channel retailing with the introduction of Tesco apps for the iPhone and Android mobile phones allowing customers to scan barcodes of items to add to a shopping list which they can then either refer to in store or order for delivery.  John Lewis Partnership was a very deserving winner of The Oracle Retailer of the Year award for their overall dedication to excellent retailing practices.  The business was also named the American Express Marketing/Advertising Campaign of the Year award for their memorable 'Never Knowingly Undersold' advert series, which included a very successful viral video and radio campaign with Fyfe Dangerfield's cover of Billy Joel's 'She's Always a Woman' used for the adverts.  Store Design of the Year was another exciting category with Topshop taking the accolade for its flagship Oxford Street store in London, which combines boutique concession-style stalls with high fashion displays and exclusive collections from leading designers.  The store even has its own hairdressers and food hall, making it a truly all-inclusive fashion retail experience and a global landmark for any self-respecting international fashion shopper. Over the next few weeks we'll be exploring some of the winning entries in more detail here on the blog, so keep an eye out for some unique insights into how the winning retailers have made such remarkable achievements.

  • Algorithm to Find the Aggregate Mass of "Granola Bar"-Like Structures?

    - by Stuart Robbins
    I'm a planetary science researcher and one project I'm working on is N-body simulations of Saturn's rings. The goal of this particular study is to watch as particles clump together under their own self-gravity and measure the aggregate mass of the clumps versus the mean velocity of all particles in the cell. We're trying to figure out if this can explain some observations made by the Cassini spacecraft during the Saturnian summer solstice when large structures were seen casting shadows on the nearly edge-on rings. Below is a screenshot of what any given timestep looks like. (Each particle is 2 m in diameter and the simulation cell itself is around 700 m across.) The code I'm using already spits out the mean velocity at every timestep. What I need to do is figure out a way to determine the mass of particles in the clumps and NOT the stray particles between them. I know every particle's position, mass, size, etc., but I don't know easily that, say, particles 30,000-40,000 along with 102,000-105,000 make up one strand that to the human eye is obvious. So, the algorithm I need to write would need to be a code with as few user-entered parameters as possible (for replicability and objectivity) that would go through all the particle positions, figure out what particles belong to clumps, and then calculate the mass. It would be great if it could do it for "each" clump/strand as opposed to everything over the cell, but I don't think I actually need it to separate them out. The only thing I was thinking of was doing some sort of N2 distance calculation where I'd calculate the distance between every particle and if, say, the closest 100 particles were within a certain distance, then that particle would be considered part of a cluster. But that seems pretty sloppy and I was hoping that you CS folks and programmers might know of a more elegant solution? Edited with My Solution: What I did was to take a sort of nearest-neighbor / cluster approach and do the quick-n-dirty N2 implementation first. So, take every particle, calculate distance to all other particles, and the threshold for in a cluster or not was whether there were N particles within d distance (two parameters that have to be set a priori, unfortunately, but as was said by some responses/comments, I wasn't going to get away with not having some of those). I then sped it up by not sorting distances but simply doing an order N search and increment a counter for the particles within d, and that sped stuff up by a factor of 6. Then I added a "stupid programmer's tree" (because I know next to nothing about tree codes). I divide up the simulation cell into a set number of grids (best results when grid size ˜7 d) where the main grid lines up with the cell, one grid is offset by half in x and y, and the other two are offset by 1/4 in ±x and ±y. The code then divides particles into the grids, then each particle N only has to have distances calculated to the other particles in that cell. Theoretically, if this were a real tree, I should get order N*log(N) as opposed to N2 speeds. I got somewhere between the two, where for a 50,000-particle sub-set I got a 17x increase in speed, and for a 150,000-particle cell, I got a 38x increase in speed. 12 seconds for the first, 53 seconds for the second, 460 seconds for a 500,000-particle cell. Those are comparable speeds to how long the code takes to run the simulation 1 timestep forward, so that's reasonable at this point. Oh -- and it's fully threaded, so it'll take as many processors as I can throw at it.

  • IIS Logfile Visualization with XNA

    - by BobPalmer
    In my office, I have a wall mounted monitor who's whole purpose in life is to display perfmon stats from our various servers.  And on a fairly regular basis, I have folks walk by asking what the lines mean.    After providing the requisite explaination about CPU utilization, disk I/O bottlenecks, etc. this is usually followed by some blank stares from the user in question, and a distillation of all of our engineering wizardry down to the phrase 'So when the red line goes up that's bad then?'   This of course would not do.  So I talked to my friends and our network admin about an option to show something more eye catching and visual, with which we could catch at a glance a feel for what was up with our site.    He initially pointed me out to a video showing GLTail and Chipmunk done in Ruby.  Realizing this was both awesome, and that I needed an excuse to do something in XNA, I decided to knock out a proof of concept for something very similar, but with a few tweaks.   Here's a link to a video of the current prototype:   http://www.youtube.com/watch?v=jM_PWZbtH2I   Essentially this app opens up a log file (even an active one) and begins pulling out the lines of text.  (Here's a good Code Project link that covers how to do tail reading from an active text file: http://www.codeproject.com/KB/files/tail.aspx).   As new data is added, a bubble is generated in the application - a GET statement comes from the left, and a POST from the right.  I then run it through a series of expression checkers, and based on the kind of statement and the pattern, a bubble of an appropriate color is generated.   For example, if I get a 500, a huge red bubble pops out.  Others are based on the part of the system the page is from - i.e. green bubbles are from our claims management subsystem, and blue bubbles are from the pages our scheduling staff use to schedule patients.  Others include the purple bubbles for security and login, and yellow bubbles for some miscellaneous pages.   The little grey bubbles represent things like images, JS, CSS, etc - and their small size makes them work like grease to keep the larger page bubbles moving.   The app is also smart enough that if it is starting to bog down with handling the physics and interactions, it will suspend new bubbles until enough have dropped off that performance can resume (you can see this slight stuttering in the sample video).   The net result is that anyone will be able to look up on the wall monitor, and instantly get a quick feel for how things are going on the floor.  Website slow?  You can get a feel for both volume and utilized modules with one glance.  Website crashing?  Look for a wall of giant red bubbles.  No activity at all?  Maybe the site is down.  Now couple this with utilization within a farm, and cross referenced with a second app showing the same kind of data from your SQL database...   As for the app itself, it's a windows XNA project with the code in C#.   The physics are handled by the Farseer physicis eingine for XNA (http://www.codeplex.com/FarseerPhysics) which is just pure goodness.  The samples are great, and I had the app up and working in two evenings (half of that was fine tuning, and the other was me coding with a kid in my lap).   My next steps include wiring this to SQL (I have some ideas...), and adding a nice configuration module.  For example, you could use polygons, etc to tie to your regex - or more entertaining things like having a little human ragdoll to represent a user login.     Once that's wrapped up and I have a chance to complete some hardening, I will be releasing the whole thing into the wild as opensource.     Feel free to ping me if you have any questions! -Bob

In real life, we are willing to pay a price for performance –i.e. to have information at our fingertips. We have run into customers opting to store a document folder path as a document metadata field. They have their reasons, half of the ECM community will agree with them, and the other half would raise an eye brow. In the end, they are getting creative to achieve their document management goals. The below steps outlines how to create a Global Rule that would store a document’s folder path in a custom metadata field: Create a Global Rule via Configuration Manager > Rules Tab > Add Then check “Is global rule with priority”. Then check “Use rule activation condition”. The go to “Edit” and check the actions for this Script Properties: Then click OK, and the following rule activation condition will appear: Then Goto to the Fields Tab and add a Rule Field: Select the target Custom Metadata Field and click Ok, then check the “Is derived field”, then “Edit”, then go to the Custom Tab in the Script Properties window and enter the below custom script: <$if #active.dCollectionPath$> <$dprDerivedValue=#active.dCollectionPath$> <$else$> <$dprDerivedValue=#active.xCollectionIDPath$> <$endif$> For more information on the dCollectionPath property, check Section 8.2 Folder Services from the Oracle® Fusion Middleware Services Reference Guide for Oracle Universal Content Management 11g Release 1 (11.1.1) http://docs.oracle.com/cd/E21043_01/doc.1111/e11011/c08_folders002.htm The above rule will keep the Custom Metadata Field updated with the Folder Path information when a document is checked in via the Content Server (CS) Web Interface or the Desktop Integration Suite (DIS).
