• What does the `dmesg` error: "composite sync not supported" mean?

  - by M. Tibbits

  Question: I see [ 20.473125] composite sync not supported and several such entries when I run dmesg. What do they mean? Background: I'm trying to debug a problem where my laptop won't suspend. Since acpi seems happy and I can suspend easily from the command line, I've turned to tracking down all boot-up errors/warnings. So I run dmesg | grep not and, amongst other shtuff, I get: 728:[ 17.267120] composite sync not supported 733:[ 18.009061] composite sync not supported 740:[ 18.159289] registered panic notifier 749:[ 18.162500] vga16fb: not registering due to another framebuffer present 757:[ 18.598251] composite sync not supported 776:[ 20.473125] composite sync not supported 777:[ 20.932266] composite sync not supported 778:[ 28.350231] composite sync not supported 779:[ 28.924913] composite sync not supported 780:[ 35.480658] composite sync not supported And the full log for the few lines right around that first appearance (line 728) is listed at the bottom of my post (I'd happily include anything else). Any ideas what could be causing this? I've read several sites: Ubuntuforums #1 IRC Chat #1 One post talks about ??Adobe flash?? causing this error? Some others also suggest that it might be an nvidia related problem, but I've got a Dell Latitude D630 with an integrated Intel graphics -- so nvidia isn't the problem.

• Repository and Ticket management in a Windows Environment

  - by saifkhan

  I’ve been using AxoSoft’s bug tracking application for a while, although and excellent piece of software I had some issues with it ·         It was SLOOOW (both desktop and web). I don’t care what Axosoft says, I tired multiple servers etc. I’ve been long enough in this field to tell you when something is not right with an app. ·         The cost! It’s not feasible for a small team.   I must say though, that they have some nice features which are not commonly found on other bug tracking software. I wouldn’t go on to list any here. I would prefer you download and try their app and see for yourself. In my quest to find a replacement, I tried a few. The successor had to satisfy the following ·         A 99.99% Windows Environment. ·         Bug Tracking. ·         Ticket Management (power users and project managers can open tickets on projects). ·         Repository (I decided to merge bug tracking and repository to get my team to be more productive). ·         Unlimited users. ·         Cost. Being the head of IT security for the firm I work for, making the decision to move data offsite was a hard decision to make, but turned out to be one I am not regretting so far. My choice was down to Altassian JIRA and codebaseHQ. I ended up going with the latter… (I still love the greenhopper from Altassian…its freaking cool!) CodebaseHQ is nice and simple and has all the features I needed. I’ve been using them for a few months now and very happy. Their pricing…well, see for yourself. I was also able to get our SVN data… (Yes, SVN! I don’t go near the Visual Sourcesafe thing…it’s not that safe (pardon the pun). I am hearing some nice things about TFS 2010) over to codebaseHQ. We use VisualSVN to access repositories. …so if you are a Windows developer (or team) codebaseHQ is worth checking out!

• Why learn Flash Builder 4 (Flex) when I can just use Flash Professional?

  - by Jason McKenna

  I want to learn Flash Builder 4 (Flex) because I see so many jobs requesting experience with it. I also just like knowing stuff. I am also very interested in focusing on RIA development now. BUT... can anyone tell me CLEARLY why the heck I would ever use FLEX over Flash Pro? It is a time investment, so is it worth it? All I read are misguided posts about how Flash Pro is for games and banner ads, and Flex is for programmers and RIAs blah blah... this simply isn't so from my 9 years of contracting experience. I'm 99.9% certain that I can build anything a flex developer can build, but using Flash Pro. I can build powerful AS3-driven apps for the desktop, mobile device, or browser, and I can link to databases with XML and I can import text files and communicate with ColdFusion and everything. The advantage with Flash Pro is that I can also easily and clearly animate transitions and build custom elements that look the way I want/need them to look for my specific client. Why would I want to use a bunch of pre-built components that drive my file sizes to the moon? Who is happy with a drag-n-drop button? Is Flex just a thing made for programmer people with no artistic inclination? What is the advantage of using it? It takes me back to Visual Basic class. Seems like a pain to have to use multiple tools to import crap from Flash Pro into Flex and yada yada... why when I can do it all nicely in Flash Pro to begin with. Am I clueless, or missing some major piece of the puzzle? Thanks for any clarity. PS, I couldn't care less about the code editors. It ain't that bad people. They make it out like the thing doesn't even respond to keyboard input or something. Does everything I need it do anyways. Please help out here. If I just don't need to learn it, I don't want to waste the time.

• My Dog, Cross-Channel Shopping, and Fusion SCM

  - by Kathryn Perry

  A guest post by Mark Carson, Director, Oracle Fusion Supply Chain Management I was walking my dog Max in an open space behind my house. As we tromped through the tall weeds I remembered it is tick season and that I should get Max some protection. While he sniffed merrily in the tick infested brush, I started shopping in the middle of an open field on my phone. I thought it would be convenient to pick up the tick medicine from a pet store on the way home. Searching the pet store website I saw that they had the medicine, but there was no information on whether the store had any in stock and there were no options for shipping it to the store for pickup. I could return it, but not pick it up which seamed kind of odd. I really didn't feel like making calls to the local stores to find out if they had it. Since the product is popular, I tried one of the large 'everything' stores. Browsing its website I could see that it could be shipped to me, shipped to the store for free, and that the store nearest to me had it in stock. Needless to say, this store became a better option. This experience is a small example of why retailers, distributors, and manufactures have placed a high priority on enabling 'cross-channel commerce.' Shoppers like you and me expect to be able to search, compare, buy and return products on-line and over the phone using a variety of devices including PDAs, tablets and in-store kiosks. The pet store lost my business because its web channel had limited information about its stores. I have spoken with many customers and prospects about cross-channel commerce. They all realize the business implications and urgency behind cross-channel commerce but recognize there are challenges to enable it. New and existing applications must be integrated together globally through a consistent cross-channel business process. Integration is required between applications that provide the initial shopping experience and delivery applications associated with warehouses, stores, and partners. The enablement must be accomplished in a flexible way to react to fast-changing product portfolios and new acquisitions, while at the same time minimizing costs through reuse of existing systems. Meanwhile, the business must continue to grow and decision makers need to balance new capability with peak seasons. The challenges above are not unique to retail. Any customer in any industry who has multiple points for capturing orders and multiple points for fulfilling orders will face these challenges. With this in mind, we had a unique opportunity in Fusion SCM to re-think how to build a set of modular and flexible applications in the order management space that would make these challenges easier to conquer. The results are Fusion Distributed Order Orchestration and Global Order Promising. These applications can help companies, such as the pet store, enable true cross-channel commerce. The apps provide highly adaptable and flexible business processes to automate order orchestration across multiple cross-channel systems. They also show a global view of supply across warehouses, stores, and partners for real-time availability and more accurate order promising. Additional capability includes a standards-based integration framework for seamless execution and the ability to reuse existing systems for faster and lower cost implementations. OK, that was a mouthful of features and benefits. As Max waited to cross the street (he can do basic math too), I wondered if he could relate. He does not care about leash laws, pick-up courtesy, where he can/can't walk, what time of day it is, or even ticks. He does not care about how all these things could make walking complicated. He just wants to walk. Similarly, customers just want to shop and companies just want to make it easier to sell and deliver. You can learn more about Distributed Order Orchestration and Global Order Promising in cross-channel here.

• Programmatically updating one update panel elements from another update panel elements

  - by Jalpesh P. Vadgama

  While taking interviews for asp.net candidate I am often asking this question but most peoples are not able to give this answer. So I decided to write a blog post about this. Here is the scenario. There are two update panels in my html code in first update panel there is textbox hello world and another update panel there is a button called btnHelloWorld. Now I want to update textbox text in button click event without post back. But in normal scenario It will not update the textbox text as both are in different update panel. Here is the code for that. <form id="form1" runat="server"> <asp:ScriptManager ID="myScriptManager" runat="server" EnableCdn="true"></asp:ScriptManager> <asp:UpdatePanel ID="firstUpdatePanel" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:TextBox ID="txtHelloWorld" runat="server"></asp:TextBox> </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel ID="secondUpdatePanel" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:Button ID="btnHelloWorld" runat="server" Text="Print Hello World" onclick="btnHelloWorld_Click" /> </ContentTemplate> </asp:UpdatePanel> </form> Here comes magic!!. Lots of people don’t know that update panel are providing the Update method from which we can programmatically update the update panel elements without post back. Below is code for that. protected void btnHelloWorld_Click(object sender, System.EventArgs e) { txtHelloWorld.Text = "Hello World!!!"; firstUpdatePanel.Update(); } That’s it here I have updated the firstUpdatePanel from the code!!!. Hope you liked it.. Stay tuned for more..Happy Programming.. Technorati Tags: UpdatePanel,ASP.NET

• Ubuntu on Pandaboard giving me troubles

  - by Jeroen Jacobs

  I'm trying to install the OMAP4 extras for ubuntu on my pandaboard. For some reason, a few packages can't seem to be agree with eachother. This what I did so far: installed on Ubuntu 11.10 on sd card Powered on Pandaboard and let it finish it's initial install Did an "apt-get update" and "apt-get upgrade", to install updates So far, everything went fine, and I was quite happy with my Pandaboard, but then I made the mistake of typing this: apt-get install ubuntu-imap4-extras At first, everything seemed ok, and it started downloading and installing. But then after a while it just crashed. I tried it again but then it gave me this: Reading package lists... Done Building dependency tree Reading state information... Done ubuntu-omap4-extras is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: gstreamer0.10-openmax : Depends: gstreamer0.10-plugins-bad but it is not going to be installed gstreamer0.10-plugin-ducati : Depends: gstreamer0.10-plugins-bad but it is not going to be installed ubuntu-omap4-extras-multimedia : Depends: gstreamer0.10-plugins-bad (>= 0.10.22-2ubuntu4+ti1.5) but it is not going to be installed E: Unmet dependencies.

• SSIS Technique to Remove/Skip Trailer and/or Bad Data Row in a Flat File

  - by Compudicted

  I noticed that the question on how to skip or bypass a trailer record or a badly formatted/empty row in a SSIS package keeps coming back on the MSDN SSIS Forum. I tried to figure out the reason why and after an extensive search inside the forum and outside it on the entire Web (using several search engines) I indeed found that it seems even thought there is a number of posts and articles on the topic none of them are employing the simplest and the most efficient technique. When I say efficient I mean the shortest time to solution for the fellow developers. OK, enough talk. Let’s face the problem: Typically a flat file (e.g. a comma delimited/CSV) needs to be processed (loaded into a database in most cases really). Oftentimes, such an input file is produced by some sort of an out of control, 3-rd party solution and would come in with some garbage characters and/or even malformed/miss-formatted rows. One such example could be this imaginary file: As you can see several rows have no data and there is an occasional garbage character (1, in this example on row #7). Our task is to produce a clean file that will only capture the meaningful data rows. As an aside, our output/target may be a database table, but for the purpose of this exercise we will simply re-format the source. Let’s outline our course of action to start off: Will use SSIS 2005 to create a DFT; The DFT will use a Flat File Source to our input [bad] flat file; We will use a Conditional Split to process the bad input file; and finally Dump the resulting data to a new [clean] file. Well, only four steps, let’s see if it is too much of work. 1: Start the BIDS and add a DFT to the Control Flow designer (I named it Process Dirty File DFT): 2, and 3: I had added the data viewer to just see what I am getting, alas, surprisingly the data issues were not seen it:   What really is the key in the approach it is to properly set the Conditional Split Transformation. Visually it is: and specifically its SSIS Expression LEN([After CS Column 0]) > 1 The point is to employ the right Boolean expression (yes, the Conditional Split accepts only Boolean conditions). For the sake of this post I re-named the Output Name “No Empty Rows”, but by default it will be named Case 1 (remember to drag your first column into the expression area)! You can close your Conditional Split now. The next part will be crucial – consuming the output of our Conditional Split. Last step - #4: Add a Flat File Destination or any other one you need. Click on the Conditional Split and choose the green arrow to drop onto the target. When you do so make sure you choose the No Empty Rows output and NOT the Conditional Split Default Output. Make the necessary mappings. At this point your package must look like: As the last step will run our package to examine the produced output file. F5: and… it looks great!

• Using lookahead assertions in regular expressions

  - by Greg Jackson

  I use regular expressions on a daily basis, as my daily work is 90% in Perl (legacy codebase, but that's a different issue). Despite this, I still find lookahead and lookbehind to be terribly confusing and often unreadable. Right now, if I were to get a code review with a lookahead or lookbehind, I would immediately send it back to see if the problem can be solved by using multiple regular expressions or a different approach. The following are the main reasons I tend not to like them: They can be terribly unreadable. Lookahead assertions, for example, start from the beginning of the string no matter where they are placed. That, among other things, can cause some very "interesting" and non-obvious behaviors. It used to be the case that many languages didn't support lookahead/lookbehind (or supported them as "experimental features"). This isn't the case quite as much, but there's still always the question as to how well it's supported. Quite frankly, they feel like a dirty hack. Regexps often already are, but they can also be quite elegant, and have gained widespread acceptance. I've gotten by without any need for them at all... sometimes I think that they're extraneous. Now, I'll freely admit that especially the last two reasons aren't really good ones, but I felt that I should enumerate what goes through my mind when I see one. I'm more than willing to change my mind about them, but I feel that they violate some of my core tenets of programming, including: Code should be as readable as possible without sacrificing functionality -- this may include doing something in a less efficient, but clearer was as long as the difference is negligible or unimportant to the application as a whole. Code should be maintainable -- if another programmer comes along to fix my code, non-obvious behavior can hide bugs or make functional code appear buggy (see readability) "The right tool for the right job" -- I'm sure you can come up with contrived examples that could use lookahead, but I've never come across something that really needs them in my real-world development work. Is there anything that they're really the best tool for, as opposed to, say, multiple regexps (or, alternatively, are they the best tool for most cases they're used for today). My question is this: Is it good practice to use lookahead/lookbehind in regular expressions, or are they simply a hack that have found their way into modern production code? I'd be perfectly happy to be convinced that I'm wrong about this, and simple examples are useful for examples or illustration, but by themselves, won't be enough to convince me.

• Does Your Customer Engagement Create an Ah Feeling?

  - by Richard Lefebvre

  An (Oracle CX Blog) article by Christina McKeon Companies that successfully engage customers all have one thing in common. They make it seem easy for the customer to get what they need. No one would argue that brands don’t want to leave customers with this “ah” feeling. Since 94% of customers who have a low-effort service experience will buy from that company again, it makes financial sense for brands.1 Some brands are thinking differently about how they engage their customers to create ah feelings. How do they do it? Toyota is a great example of using smart assistance technology to understand customer intent and answer questions before customers hit the submit button online. What is unique in this situation is that Toyota captures intent while customers are filling out email forms. Toyota analyzes the data in the form and suggests responses before the customer sends the email. The customer gets the right answer, and the email never makes it to your contact center — which makes you and the customer happy. Most brands are fully aware of chat as a service channel, but some brands take chat to a whole new level. Beauty.com, part of the drugstore.com and Walgreens family of brands, uses live chat to replicate the personal experience that one would find at high-end department store cosmetic counters. Trained beauty advisors, all with esthetician or beauty counter experience, engage in live chat sessions with online shoppers to share immediate advice on the best products for their personal needs. Agents can watch customer activity online and determine the right time to reach out and offer help, just as help would be offered in a brick-and-mortar store. And, agents can co-browse along with the customer helping customers with online check-out. These personal chat discussions also give Beauty.com the opportunity to present products, advertise promotions, and resolve customer issues when they arise. Beauty.com converts approximately 25% of chat sessions into product orders. Photobox, the European market leader in online photo services, wanted to deliver personal and responsive service to its 24 million members. It ensures customer inquiries on personalized photo products are routed based on agent knowledge so customers get what they need from the company experts. By using a queuing system to ensure that the agent with the most appropriate knowledge handles the query, agent productivity increased while response times to 1,500 customer queries per day decreased. A real-time dashboard prevents agents from being overloaded with queries. This approach has produced financial results with a 15% increase in sales to existing customers and a 45% increase in orders from newly referred customers.

• Producing a smooth mesh from density cloud and marching cubes

  - by Wardy

  Based on my results from this question I decided to build myself a 3D noise map containing float values in place of my existing boolean point values. The effect I'm trying to produce is something like this, rather than typical rolling hills; which should explain the "missing cubes" in the image below. If I render my density map in normal "minecraft mode" (1 block per point in the density map) varying the size of the cube based on the value in my density map (floats in the range 0 to 1) I get something like this: I'm now happy that I can produce a density map for the marching cubes algorithm (which will need a little tweaking) but for some reason when I run it through my implementation it's not producing what I expect. My problem is that I'm getting something like the first image in this answer to my previous question, when I want to achieve the effect in the second image. Upon further investigation I can't see how marching cubes does the "move vertex along the edge" type logic (i.e. the difference between the two images on my previous link). I see that it does do some interpolation, but I'm not convinced I have the correct understanding of what I think it should do, because the code in question appears to give the same result regardless of whether I use boolean or float values. I took the code from here which is a C# implementation of marching cubes, but instead of using the MarchingCubesPrimitive I modified it to accept an object of type IDrawable, containing lists for the various collections (vertices, normals, UVs, indices), the logic was otherwise untouched. My understanding is that given a very low isovalue the accuracy level of the surface being rendered should increase, so in short "less 45 degree slows more rolling hills" type mesh output. However this isn't what I'm seeing. Have I missed something or is the implementation flawed and need to be fixed? EDIT: A little more detail on what I am seeing when I "marching cube" the data. Ok so firstly, ignore the fact that the meshes created by the chunks don't "connect" (i'll probably raise another question about this later). Then look at the shaping of the island, it's too ... square, from the voxels rendered as boxes you get the impression there's a clean soft gradual hill and yet from the image there are sharp falling edges even in the most central areas where the gradient in the first image looks the most smooth. The data is "regenerated" each time I run this so no 2 islands come out the same, and it's purely random so not based on noise, but still, how can it look so smooth in 1 image and so not smooth in the other?

• #OOW 2012: Big Data and The Social Revolution

  - by Eric Bezille

  As what was saying Cognizant CSO Malcolm Frank about the "Futur of Work", and how the Business should prepare in the face of the new generation  not only of devices and "internet of things" but also due to their users ("The Millennials"), moving from "consumers" to "prosumers" :  we are at a turning point today which is bringing us to the next IT Architecture Wave. So this is no more just about putting Big Data, Social Networks and Customer Experience (CxM) on top of old existing processes, it is about embracing the next curve, by identifying what processes need to be improve, but also and more importantly what processes are obsolete and need to be get ride of, and new processes put in place. It is about managing both the hierarchical and structured Enterprise and its social connections and influencers inside and outside of the Enterprise. And this does apply everywhere, up to the Utilities and Smart Grids, where it is no more just about delivering (faster) the same old 300 reports that have grown over time with those new technologies but to understand what need to be looked at, in real-time, down to an hand full relevant reports with the KPI relevant to the business. It is about how IT can anticipate the next wave, and is able to answers Business questions, and give those capabilities in real-time right at the hand of the decision makers... This is the turning curve, where IT is really moving from the past decade "Cost Center" to "Value for the Business", as Corporate Stakeholders will be able to touch the value directly at the tip of their fingers. It is all about making Data Driven Strategic decisions, encompassed and enriched by ALL the Data, and connected to customers/prosumers influencers. This brings to stakeholders the ability to make informed decisions on question like : “What would be the best Olympic Gold winner to represent my automotive brand ?”... in a few clicks and in real-time, based on social media analysis (twitter, Facebook, Google+...) and connections link to my Enterprise data. A true example demonstrated by Larry Ellison in real-time during his yesterday’s key notes, where “Hardware and Software Engineered to Work Together” is not only about extreme performances but also solutions that Business can touch thanks to well integrated Customer eXperience Management and Social Networking : bringing the capabilities to IT to move to the IT Architecture Next wave. An example, illustrated also todays in 2 others sessions, that I had the opportunity to attend. The first session bringing the “Internet of Things” in Oil&Gaz into actionable decisions thanks to Complex Event Processing capturing sensors data with the ready to run IT infrastructure leveraging Exalogic for the CEP side, Exadata for the enrich datasets and Exalytics to provide the informed decision interface up to end-user. The second session showing Real Time Decision engine in action for ACCOR hotels, with Eric Wyttynck, VP eCommerce, and his Technical Director Pascal Massenet. I have to close my post here, as I have to go to run our practical hands-on lab, cooked with Olivier Canonge, Christophe Pauliat and Simon Coter, illustrating in practice the Oracle Infrastructure Private Cloud recently announced last Sunday by Larry, and developed through many examples this morning by John Folwer. John also announced today Solaris 11.1 with a range of network innovation and virtualization at the OS level, as well as many optimizations for applications, like for Oracle RAC, with the introduction of the lock manager inside Solaris Kernel. Last but not least, he introduced Xsigo Datacenter Fabric for highly simplified networks and storage virtualization for your Cloud Infrastructure. Hoping you will get ready to jump on the next wave, we are here to help...

• Graduate Life in Oracle by Ramakrishna Nalabothula

  - by david.talamelli

  Preparation for the BIG interview: I prepared in both technical and logical aspects to face the Oracle Interview. I had to cover almost all main areas in technical and many types of problems in logical areas. We attended mock- interviews and written tests at our college, browsed websites and communities. Having started with such a rigorous preparation before Oracle visited the college; it was possible for me to make it into the list of final selection. I put in a big effort to reach this position and I am very happy to achieve this. Why I chose Oracle: Oracle is one of the best technology providers and has a large customer base. I think it is not an easy job to offer services to that many customers. So, the company needs young and dynamic people and I wanted to be one among them. This gave me spirit and led me to walk into Oracle. I am working on different technologies and learning something new in the field. Having many customers is challenging Oracle and my work is challenging me. I am confident enough that customers to both me and Oracle will never lose their faith. Learning at Oracle: The style of learning is good and never resembles a classroom session in a college. It is always fun to learn here. There is no exam to track the performance. There is enough time until we completely learn it. There is no concept of stiff competition. Peers help through KT (Knowledge Transfers) and there are good resources in the Oracle to learn. People are always there to direct you to those. There are lots of opportunities for Web learning too! My Work Area: My team gives me a great opportunity to offer service to the entire product. There were no situations when I got tense with my work or targets and deliverables. I work with a Global Team and my manager is based in the UK. I have a lot of freedom and flexibility. I use the work from home option in case of any disturbances in the city or due to personal problems. I have a weekly meeting with my manager and use Instant Messenger for status updates. My manager plans very well to give me enough time to complete tasks. I have good coordination from the team towards our deadlines. My work has also brought me close to many people across various technology and product teams. I am glad to make many friends across Oracle. I am enjoying my time and work here. I cover all the major activities in the team. I am thankful to everyone from the Development and Quality Assurance Team to have high confidence in me by assigning such big responsibilities. Primary tasks are maintaining the environments that are very unstable at times. This really requires big time and effort to trace the root causes. I am working and still learning on all these areas. The happiest thing is I got chances to travel to USA & UK for training and for supporting a few customer demo projects. I have got to explore more across two countries and got sponsored to visit the places around due to Oracle's policies. I am very much thankful for these what I have from Oracle and for the cooperation there from other colleagues. Fun at Work: Oracle has a club from Employees to conduct games and events. I had an opportunity to participate in competitions, tournaments inside Oracle and Inter-Corporate for all games. I thank Oracle for providing me all these opportunities and I would like to extend my thanks to Senior Management for their confidence in me. I thank Oracle HR Recruiting Team too for selecting me into Oracle and giving me this opportunity to share my experience and feelings. Ramakrishna Nalabothula

• Oracle Employees Support New World Record for IYF Children's Hour

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 960 students ‘crouched’, ‘touched’ and ‘set’ under the watchful eye of International Rugby Referee Alain Roland, and supported by Oracle employees, to successfully set a new world record for the World’s Largest Scrum to raise funds and awareness for the Irish Youth Foundation. Last year Oracle Employees supported the Irish Youth Foundation by donating funds from their payroll through the Giving Tree Appeal. We were the largest corporate donor to the IYF by raising €3075. To acknowledge our generosity the IYF asked Oracle Leadership in Society team members to participate in their most recent campaign which was to break the Guinness Book of Records by forming the World’s Largest Rugby Scrum. This was a wonderful opportunity for Oracle’s Leadership in Society to promote the charity, support education and to make a mark in the Corporate Social Responsibility field. The students who formed the scrum also gave up their lunch money and raised a total of €3000. This year we hope Oracle Employees will once again support the IYF with the challenge to match that amount. On the 24th of October the sun shone down on the streaming lines of students entering the field. 480 students were decked out in bright red Oracle T-Shirts against the other 480 in blue and white jerseys - all ready to form a striking scrum. Ryan Tubridy the host of the event made the opening announcement and with the blow of a whistle the Scum began. 960 students locked tight together with the Leinster players also at each side. Leinster Manager Matt O’Connor was there along with presenters Ryan Tubridy and George Hook to assist with getting the boys in line and keeping the shape of the scrum. In accordance with Guinness Book of Records rules, the ball was fed into the scrum properly by Ireland and Leinster scrum-half, Eoin Reddan, and was then passed out the line to his Leinster team mates including Ian Madigan, Brendan Macken and Jordi Murphy, also proudly sporting the Oracle T-Shirt. The new World Record was made, everyone gave a big cheer and thankfully nobody got injured! Thank you to everyone in Oracle who donated last year through the Giving Tree Appeal. Your generosity has gone a long way to support local groups both. Last year’s donation was so substantial that the IYF were able to spread it across two youth groups: The first being Ballybough Youth Project in Dublin. The funding gave them the chance to give 24 young people from their project the chance to get away from the inner city and the problems and issues they face in their daily life by taking a trip to the Cavan Centre to spend a weekend away in a safe and comfortable environment; a very rare holiday in these young people’s lives. The Rahoon Family Centre. Used the money to help secure the long term sustainability of their project. They act as an educational/social/fun project that has been working with disadvantaged children for the past 16 years. Their aim is to change young people’s future with fun /social education and supporting them so they can maximize their creativity and potential. We hope you can help support this worthy cause again this year, so keep an eye out for the Children’s Hour and Giving Tree Appeal! About the Irish Youth Foundation The IYF provides opportunities for marginalised children and young people facing difficult and extreme conditions to experience success in their lives. It passionately believes that achievement starts with opportunity. The IYF’s strategy is based on providing safe places where children can go after school; to grow, to learn and to play; and providing opportunities for teenagers from under-served communities to succeed and excel in their lives. The IYF supports innovative grassroots projects operated by dedicated professionals who understand young people and care about them. This allows the IYF to focus on supporting young people at risk of dropping out of school and, in particular, on the critical transition from primary to secondary school; and empowering teenagers from disadvantaged neighborhoods to become engaged in their local communities.

• Where and how to mention Stackoverflow participation in the résumé?

  - by Sandeepan Nath

  I think I have good enough reputation on SO now - here is my profile - http://stackoverflow.com/users/351903/sandeepan-nath. Well, this may not be that much as compared to so many other users out there but I am happy with mine. So, I was thinking of adding my profile link on my résumé. (Just the profile link and not that "I have this much reputation on SO"). Those who haven't seen, can see this question Would you put your stackoverflow profile link on your CV / Resume?. How would this look like? Forums/Blogs/Miscellaneous others No blogging as yet but active participant in Stackoverflow. My profile link - http://stackoverflow.com/users/351903/sandeepan-nath I think of putting this section after Project Details and Technical Expertise sections. Any tips/advice? Thanks Update MKO has made a very good point - "do you really want a potential employeer to be able to evaluate in detail everything you've ever written on SO". I thought of commenting but it would be too long - In my questions/answers I put a lot of statements like - "AFAIK ...", "following are my assumptions so far ...", "am I correct to conclude that... ?", "I doubt if it is possible to ..." etc. when I am not sure about something and I rarely involve in fights with other users. However I do argue on topics sometimes if I feel it is necessary and if I have a valid point. I do accept my mistakes and apologize for the same. As we all know nobody is perfect. I must have written many things which may be judged as wrong by a potential employer. But what if the same employer notices that I have improved in the quality of content by comparing old content with new one? Isn't that great? I also try to go back to older questions/answers and put corrective comments etc. when I feel I was wrong or if I can improve my post. Of course there are many employers who want you (potential employees) to be correct each and every time. They immediately remove you from consideration when you say a single incorrect thing. I have personally met such an interviewer few months back. He didn't even care to listen to any good thing I had done after he found a single wrong thing. Now the question is do you really care to work with such people? Or do you like those people who give value to the fact that you are striving to improve every day. I personally prefer the latter.

• Tuning Default WorkManager - Advantages and Disadvantages

  - by Murali Veligeti

  Before discussing on Tuning Default WorkManager, lets have a brief introduction on What is Default WorkManger Before Weblogic Server 9.0 release, we had the concept of Execute Queues. WebLogic Server (before WLS 9.0), processing was performed in multiple execute queues. Different classes of work were executed in different queues, based on priority and ordering requirements, and to avoid deadlocks. In addition to the default execute queue, weblogic.kernel.default, there were pre-configured queues dedicated to internal administrative traffic, such as weblogic.admin.HTTP and weblogic.admin.RMI.Users could control thread usage by altering the number of threads in the default queue, or configure custom execute queues to ensure that particular applications had access to a fixed number of execute threads, regardless of overall system load. From WLS 9.0 release onwards WebLogic Server uses is a single thread pool (single thread pool which is called Default WorkManager), in which all types of work are executed. WebLogic Server prioritizes work based on rules you define, and run-time metrics, including the actual time it takes to execute a request and the rate at which requests are entering and leaving the pool.The common thread pool changes its size automatically to maximize throughput. The queue monitors throughput over time and based on history, determines whether to adjust the thread count. For example, if historical throughput statistics indicate that a higher thread count increased throughput, WebLogic increases the thread count. Similarly, if statistics indicate that fewer threads did not reduce throughput, WebLogic decreases the thread count. This new strategy makes it easier for administrators to allocate processing resources and manage performance, avoiding the effort and complexity involved in configuring, monitoring, and tuning custom executes queues. The Default WorkManager is used to handle thread management and perform self-tuning.This Work Manager is used by an application when no other Work Managers are specified in the application’s deployment descriptors. In many situations, the default Work Manager may be sufficient for most application requirements. WebLogic Server’s thread-handling algorithms assign each application its own fair share by default. Applications are given equal priority for threads and are prevented from monopolizing them. The default work-manager, as its name tells, is the work-manager defined by default.Thus, all applications deployed on WLS will use it. But sometimes, when your application is already in production, it's obvious you can't take your EAR / WAR, update the deployment descriptor(s) and redeploy it.The default work-manager belongs to a thread-pool, as initial thread-pool comes with only five threads, that's not much. If your application has to face a large number of hits, you may want to start with more than that.Well, that's quite easy. You have  two option to do so.1) Modify the config.xmlJust add the following line(s) in your server definition : <server> <name>AdminServer</name> <self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min> <self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max> [...] </server> 2) Adding some JVM parameters Add the following system property in setDomainEnv.sh/setDomainEnv.cmd or startWebLogic.sh/startWebLogic.cmd : -Dweblogic.threadpool.MinPoolSize=100 -Dweblogic.threadpool.MaxPoolSize=100 Reboot WLS and see the option has been taken into account . Disadvantage: So far its fine. But here there is an disadvantage in tuning Default WorkManager. Internally Weblogic Server has many work managers configured for different types of work.  if we run out of threads in the self-tuning pool(because of system property -Dweblogic.threadpool.MaxPoolSize) due to being undersized, then important work that WLS might need to do could be starved.  So, while limiting the self-tuning would limit the default WorkManager and internally it also limits all other internal WorkManagers which WLS uses.So the best alternative is to override the default WorkManager that means creating a WorkManager for the Application and assign the WorkManager for the application instead of tuning the Default WorkManager.

• ATI (fglrx) Dual monitor / laptop hot-plugging

  - by Brendan Piater

  I feel like I've gone back 5 years on my desktop today. I'll try not dump to much frustration here... I been running 12.04 since alpha with the ATI open source drivers and the gnome 3 desktop. I been generally very happy with them with only small issues along the way. Now of course it does not support 3D acceleration 100%, so games like my newly purchased Amnesia from the Humble bundle would not play. OK, no worries, the ATI driver is in the repos so let me have a go I thought. With all this testing that's been done with multi-monitor support, what could go wrong...? How I use my computer: It's laptop, with a HD 3670 card in it. I spend about 50% of the time working directly on the laptop (at home) and about 50% of the time working with an additional display connected (at work), multi desktop environment. What happening now: installed drivers things seemed to working, save some small other bugs (not critical) this morning I take my machine and plug the additional monitor into it, and nothing happens... ok fine. open "displays" try configure dual display, won't work open ati config "thing" (cause it is a thing, a crap thing) and set-up monitors there reboot it says (oh ffs, really.... ok) reboot, login and wow, I got a gnome 2 desktop (presume gnome 3 fall back) and no multi-monitor...great. (screenshot: http://ubuntuone.com/5tFe3QNFsTSIGvUSVLsyL7 ) after getting into a situation where I had to Ctrl + Alt + Del to get out of a frozen display, I eventually manage to set-up a single display desktop on the "main" monitor ok.. time to go home... unplug monitor... nothing happens.. oh boy here we go... try displays again, nothing, just hangs the display.. great. crash all the apps and reboot... So it's been a trying day... What I really hope is that someone else has figured out how to avoid this PAIN. Please help with a solution that: allows me run fglrx (so I can run the games I want) allows me to hot-plug a monitor to my laptop and remove it again allows me to change the display so include the hot-plugged monitor (preferable automatically like it did with the open drivers) Next best if that's not possible: switch between laptop only display and monitor only display easily (i.e. not having to reboot/logout/suspened etc) Really appreciate the time of anyone that has a solution. Thanks in advance. Regards Brendan PS: I guess I should file a bug about this too, so some direction as to the best place to file this would be appreciated too.

• Encrypting your SQL Server Passwords in Powershell

  - by laerte

  A couple of months ago, a friend of mine who is now bewitched by the seemingly supernatural abilities of Powershell (+1 for the team) asked me what, initially, appeared to be a trivial question: "Laerte, I do not have the luxury of being able to work with my SQL servers through Windows Authentication, and I need a way to automatically pass my username and password. How would you suggest I do this?" Given that I knew he, like me, was using the SQLPSX modules (an open source project created by Chad Miller; a fantastic library of reusable functions and PowerShell scripts), I merrily replied, "Simply pass the Username and Password in SQLPSX functions". He rather pointed responded: "My friend, I might as well pass: Username-'Me'-password 'NowEverybodyKnowsMyPassword'" As I do have the pleasure of working with Windows Authentication, I had not really thought this situation though yet (and thank goodness I only revealed my temporary ignorance to a friend, and the embarrassment was minimized). After discussing this puzzle with Chad Miller, he showed me some code for saving passwords on SQL Server Tables, which he had demo'd in his Powershell ETL session at Tampa SQL Saturday (and you can download the scripts from here). The solution seemed to be pretty much ready to go, so I showed it to my Authentication-impoverished friend, only to discover that we were only half-way there: "That's almost what I want, but the details need to be stored in my local txt file, together with the names of the servers that I'll actually use the Powershell scripts on. Something like: Server1,UserName,Password Server2,UserName,Password" I thought about it for just a few milliseconds (Ha! Of course I'm not telling you how long it actually took me, I have to do my own marketing, after all) and the solution was finally ready. First , we have to download Library-StringCripto (with many thanks to Steven Hystad), which is composed of two functions: One for encryption and other for decryption, both of which are used to manage the password. If you want to know more about the library, you can see more details in the help functions. Next, we have to create a txt file with your encrypted passwords:$ServerName = "Server1" $UserName = "Login1" $Password = "Senha1" $PasswordToEncrypt = "YourPassword" $UserNameEncrypt = Write-EncryptedString -inputstring $UserName -Password $PasswordToEncrypt $PasswordEncrypt = Write-EncryptedString -inputstring $Password -Password $PasswordToEncrypt "$($Servername),$($UserNameEncrypt),$($PasswordEncrypt)" | Out-File c:\temp\ServersSecurePassword.txt -Append $ServerName = "Server2" $UserName = "Login2" $Password = "senha2" $PasswordToEncrypt = "YourPassword" $UserNameEncrypt = Write-EncryptedString -inputstring $UserName -Password $PasswordToEncrypt $PasswordEncrypt = Write-EncryptedString -inputstring $Password -Password $PasswordToEncrypt "$($Servername),$($UserNameEncrypt),$($PasswordEncrypt)" | Out-File c:\temp\ ServersSecurePassword.txt -Append .And in the c:\temp\ServersSecurePassword.txt file which we've just created, you will find your Username and Password, all neatly encrypted. Let's take a look at what the txt looks like: .and in case you're wondering, Server names, Usernames and Passwords are all separated by commas. Decryption is actually much more simple:Read-EncryptedString -InputString $EncryptString -password "YourPassword" (Just remember that the Password you're trying to decrypt must be exactly the same as the encrypted phrase.) Finally, just to show you how smooth this solution is, let's say I want to use the Invoke-DBMaint function from SQLPSX to perform a checkdb on a system database: it's just a case of split, decrypt and be happy!Get-Content c:\temp\ServerSecurePassword.txt | foreach { [array] $Split = ($_).split(",") Invoke-DBMaint -server $($Split[0]) -UserName (Read-EncryptedString -InputString $Split[1] -password "YourPassword" ) -Password (Read-EncryptedString -InputString $Split[2] -password "YourPassword" ) -Databases "SYSTEM" -Action "CHECK_DB" -ReportOn c:\Temp } This is why I love Powershell.

• How to debug Infopath2010 using VS2010

  - by ybbest

  In InfoPath 2010 , you can only use VSTO to write code for your form. However , when you try to debug you will see no attach to process option in the VSTO Project. In order to debug your InfoPath form , you have to do the following steps and debug using Visual Studio 2010. However , if you are not using InfoPath form services with SharePoint2010 and only using InfoPath Filler , you can see how to debug here. 1. You need to go to VSTO Project properties >> Build >> Advanced option >> Set the debug info to Full. (As shown below.) 2.Republish your form,this will rebuild your VSTO Project using the new build configurations. 3. Deploy the infopath form from the central admin and activate your form template to a site collection. If you have already deployed the form before , you need to do some clean up steps :     a.Delete all the infopath forms from the form library where you use your infopath form template as a content type     b.Remove the contentType from this form library     c.Deactivate the contype feature from the site collection features.     d.Delete the infopath form template from the central admin     e.Upload the new form template from from the central admin , you need to uncheck Upgrade the form template if it already exists     f.Activate the form template to the site collection and asscociate the contentType with your form library again. If the Above steps does not work , you need to delete the site collection and create a new one. 4. Open the FormCode.cs file you would like to debug in Visual studio 2010(just the file not the whole project),attach the w3wp.exe processes and set a breakpoint in the FormEvents_Loading event. Now if you add a new form to the form liabrary , the breakpoint should be hit.(See screenshot below) As mentioned above , if it does not hit.You might need to delete the site collection and create a new one.Delete the form template and reupload it again remember to uncheck Upgrade the form template if it already exists .Then you should be able to debug your infopath form.I do not see why debugging in InfoPath2010 is so much harder,but here we go.Happy SharePointing and InfoPathing .

• Ubuntu Install 11.10 doesn't recognize Windows 7 installation with new HDD

  - by arlendo

  Replaced my crashed HDD with a Seagate 2TB Sata (bought from a company who pulled it from a working computer, OS unknown) and did a fresh install of Windows 7. Windows shows 100MB boot partition (bootable NTFS) and 200GB Windows partition (NTFS), the rest is unallocated. Win7 Disk Management says the partitioning type is Master Boot Record. Win7 boots and runs fine. Ubuntu 11.10 Install procedes to Allocate Drive Space screen and should say This computer currently has Windows 7 on it. What would you like to do? Instead, it says something like Install doesn't detect any existing OS on this computer. When I click on Something else, the partition table shows only the unallocated space of 1.8TB. Ubuntu Disk Utility says Partitioning: Master Boot Record, but GParted Live says Partition Table: gpt. It was my original intention to have the Windows boot partition and application partition, then install Ubuntu 11.10 using boot, root, swap, and home partitions, and maybe another partition just for data (mostly photos). Currently, I would be happy if I could just get Ubuntu installed along with Win7. I am aware of the MBR limits of 3 Primary partitions and 1 Extended partition. I suspect that my new HDD is partitioned for GPT and that is why Ubuntu can't see the Win7 installation. Am I on the right track? I was going to use Windows Disk Management to convert GPT to MBR but I only have the one drive on my AMD-64 mini-computer and it says I have to empty the drive of all partitions before I can access the Convert command. And I can't find any bootable software that would allow me to do that conversion. Here is the result of sudo fdisk -l: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 224 heads, 19 sectors/track, 918004 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xd4a68c18 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 419637247 209715200 7 HPFS/NTFS/exFAT ubuntu@ubuntu:~$ Keep in mind that I'm a definite newbie to screwing around with the inner workings of Ubuntu. I previously had Ubuntu 10.04 running with Vista and I don't remember even having to partition anything that wasn't automatic in the install. Thanks for taking a look here.

• Getting Started with Kinect for Windows.

  - by Vishal

  Hello folks,      Recently I got involved in a project for building a demo application for one of our customers with Kinect for Windows. Yes, something similar what Tom Cruise did in the movie Minority Report. Waving arms, moving stuff around, swipes, speech recognition, manipulating computer screens without even touching it. Pretty cool!!! The idea in the movie showed us how technology would be after 50 years from that day.   Minority Report Movie clip.           Well, that 50 years of time frame got squeezed and recently on Feb 1st 2012, Microsoft released the official Kinect for Windows SDK. That’s just 10 years from the movie release. Although, the product is in it early stages but with developer creativity and continuously improving hardware, those features shown in the movie are not very far away from becoming a reality. Soon after releasing the SDK, Microsoft again announced in March the release of its new Kinect for Windows SDK version 1.5 which is coming out in sometime May. More history about Kinect. Anyways, so for a newbie with Kinect, where would you start. Here is what I would suggest you can do. Watch the Kinect for Windows Quick start Series by Den Fernandez. Download the Kinect for Windows SDK and start playing around with the demos in it. It also comes with some basic Kinect documentation. Coding4Fun Kinect Projects | Lot many more videos and open sources projects information. Kinect for Windows Session at Techdays NL demo by Jesus Rodriguez. Book: Beginning Kinect Programming with the Microsoft Kinect SDK.  | I did go through few of the chapters in this book and based on that, it does talk deeply about core Kinect concepts but in very easy to understand way. I would definitely suggest this book for any Kinect developers. I liked the way it explained the Gestures recognition in Chapter 6. Buy your Kinect device from either Amazon or NewEgg. You will get it cheaper then buying it from Microsoft Store. Personally, I love Newegg.com as I never had any order related or shipping issues with them. I always hate developing UI application but well, you would need to get your hands dirty with WPF too in order to work with Kinect. So get started with WPF concepts too. I will keep adding stuff to the list once I come across them but so far the above list would definitely get you started building your first Kinect apps. Till then Happy Kinecting…!!!!! Thanks, Vishal Mody

• Using INotifyPropertyChanged in background threads

  - by digitaldias

  Following up on a previous blog post where I exemplify databinding to objects, a reader was having some trouble with getting the UI to update. Here’s the rough UI: The idea is, when pressing Start, a background worker process starts ticking at the specified interval, then proceeds to increment the databound Elapsed value. The problem is that event propagation is limeted to current thread, meaning, you fire an event in one thread, then other threads of the same application will not catch it. The Code behind So, somewhere in my ViewModel, I have a corresponding bethod Start that initiates a background worker, for example: public void Start( ) { BackgroundWorker backgroundWorker = new BackgroundWorker( ); backgroundWorker.DoWork += IncrementTimerValue; backgroundWorker.RunWorkerAsync( ); } protected void IncrementTimerValue( object sender, DoWorkEventArgs e ) { do { if( this.ElapsedMs == 100 ) this.ElapsedMs = 0; else this.ElapsedMs++; }while( true ); } Assuming that there is a property: public int ElapsedMs { get { return _elapsedMs; } set { if( _elapsedMs == value ) return; _elapsedMs = value; NotifyThatPropertyChanged( "ElapsedMs" ); } } The above code will not work. If you step into this code in debug, you will find that INotifyPropertyChanged is called, but it does so in a different thread, and thus the UI never catches it, and does not update. One solution Knowing that the background thread updates the ElapsedMs member gives me a chance to activate BackgroundWorker class’ progress reporting mechanism to simply alert the main thread that something has happened, and that it is probably a good idea to refresh the ElapsedMs binding. public void Start( ) { BackgroundWorker backgroundWorker = new BackgroundWorker( ); backgroundWorker.DoWork += IncrementTimerValue; // Listen for progress report events backgroundWorker.WorkerReportsProgress = true; // Tell the UI that ElapsedMs needs to update backgroundWorker.RunWorkerCompleted += ( sender, e ) => { NotifyThatPropertyChanged( "ElapsedMs" ) }; backgroundWorker.RunWorkerAsync( ); } protected void IncrementTimerValue( object sender, DoWorkEventArgs e ) { do { if( this.ElapsedMs == 100 ) this.ElapsedMs = 0; else this.ElapsedMs++; // report any progress ( sender as BackgroundWorker ).ReportProgress( 0 ); }while( true ); } What happens above now is that I’ve used the BackgroundWorker cross thread mechanism to alert me of when it is ok for the UI to update it’s ElapsedMs field. Because the property itself is being updated in a different thread, I’m removing the NotifyThatPropertyChanged call from it’s Set method, and moving that responsability to the anonymous method that I created in the Start method. This is one way of solving the issue of having a background thread update your UI. I would be happy to hear of other cross-threading mechanisms for working in a MCP/MVC/MVVM pattern.
