  • Oracle to Join OECD Urban Roundtable for Mayors and Ministers

    - by caroline.yu
    Oracle is pleased to announce that Bastian Fischer, vice president and general manager for EMEA, Oracle Utilities, will participate in the 2010 Organisation for Economic Co-Operation and Development (OECD) Urban Roundtable for Mayors and Ministers on 25 May in France. The roundtable, hosted by OECD Secretary General Angel Gurría, will help determine how cities can contribute to green growth incentives and address the challenges to success. The OECD is developing a global Green Growth Strategy that will identify policies and approaches that can shift production and consumption towards a clean, low-carbon and sustainable economy. Already, more than 500 European cities have signed up to the 2020 carbon pledge to reduce carbon emissions by 20 per cent in ten years. This initiative is driving the adoption of innovative technologies such as the smart gird, which deliver substantial benefits to support this mission by allowing utilities to manage their distribution grids more efficiently, reducing emissions and lowering the risk of outages. A successful smart grid infrastructure will allow green cities to manage their energy usage and succeed in their pledge to meet European targets for carbon reduction, which will undoubtedly be a discussion topic at the roundtable. For more information, visit the OECD Web site.

  • Ubuntu 12.04 LTS loops the login screen unless you login as Guest

    - by Mário Silva
    I am running a VMWare Player with a Ubuntu 12.04 LTS Precise Pangloin as Guest on my Windows 7. Sometimes I get the shutdown blue screen error in Windows, this time it happened when I was running the Player. When I restarted everything Ubuntu gave the not so unfamiliar in this forum Login Loop in adminstrator login. I login and there's this black screen where I can only read: "piix4...smbus:0.0.0.07.3 Host Smbus controller not enabled" . When I go to the Prompt in root mode it fails to update and only upgraded, specially some plugins ( I think graphic plugins) which also appear in one an error message after quitting the prompt, but they´are successfully installed. They are not the error message. After that I have been working with the Fail/safe Mode recovery panel. When I try to update via Root I get errors like this: W:failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/release.gpg could not resolve 'extras/ubuntu.com There are 8 more like this referring to areas like: -archive/canonical.com -ppa.Launchpad.net -security.Ubuntu.com -Us.archive.ubuntu.com - release.gpg precise-updates/release.gpg precise_backport/release.gpg Final Message: some index files failed to download.....they have been ignored or old files are used. The black screens most of the time pass by too fast for me to pick up any information. But in general I think I have done everything I was able to in the recovery panel including updating network and graphic packages and recovering filesystem packages and the basic stuff ( I am a beginner regarding Linux ) in the root prompt. Now I am stuck in this screen with graphic options: - Run in low-graphics mode just for one session - Reconfigure Graphics - Troubleshoot the error - Exit to console login I am trying to choose to reconfigure graphics but the mouse disappears in the virtual machine screen and sometimes when options change ity´s only the first and last option. ut this happens from the blue without messages. This particular option menu is in the regular GUI style against a black screen in Terminal style. Really strange. Thanx in advance, all is welcome and appreciated.

  • JRockit R28 "Ropsten" released

    - by tomas.nilsson
    R28 is a major release (as indicated by the careless omissions of "minor" and "revision" numbers. The formal name would be R28.0.0). Our customers expect grand new features and innovation from major releases, and "Ropsten" will not disappoint. One of the biggest challenges for IT systems is after the fact diagnostics. That is - Once something has gone wrong, the act of trying to figure out why it went wrong. Monitoring a system and keeping track of system health once it is running is considered a hard problem (one that we to some extent help our customers solve already with JRockit Mission Control), but doing it after something occurred is close to impossible. The most common solution is to set up heavy logging (and sacrificing system performance to do the logging) and hope that the problem occurs again. No one really thinks that this is a good solution, but it's the best there is. Until now. Inspired by the "Black box" in airplanes, JRockit R28 introduces the Flight Recorder. Flight Recorder can be seen as an extremely detailed log, but one that is always on and that comes without a cost to system performance. With JRockit Flight Recorder the customer will be able to get diagnostics information about what happened _before_ a problem occurred, instead of trying to guess by looking at the fallout. Keywords that are important to the customer are: • Extremely detailed, always on, diagnostics information • No performance overhead • Powerful tooling to visualize the data recorded. • Enables diagnostics of bugs and SLA breaches after the fact. For followers of JRockit, other additions are: • New JMX agent that allows JRMC to be used through firewalls more easily • Option to generate HPROF dumps, compatible with tools like Eclipse MAT • Up to 64 BG compressed references (previously 4) • View memory allocation on a thread level (as an Mbean and in Mission Control) • Native memory tracking (Command line and Mbean) • More robust optimizer. • Dropping support for Java 1.4.2 and Itanium If you have any further questions, please email [email protected]. The release can be downloaded from http://www.oracle.com/technology/software/products/jrockit/index.html

  • Problems with both LightDM and GDM using DisplayLink USB monitor

    - by Austin
    When I use LightDM, it will auto-login to desktop just fine. The only problem is Compiz doesn't work, and menus don't work. I can't right-click the desktop, and I can't select program menus in the top bar (I.e clicking "File" does nothing). When I use GDM, I only get a blank blue screen and the mouse cursor. I can't Ctrl+Alt+Backspace to restart, but I can Ctrl+Alt+F1 and Ctrl+Alt+F7 to switch modes. I don't think it's auto-logging me in, but I'm not sure. It plays the login screen noise. Will update with more information when I get home! EDIT: Okay, so I did a fresh install, just to ensure I hadn't borked something playing in the console. I reconfigured my setup as I did before, with the same results. Here's what I followed. The only difference is that instead of setting "vga=normal nomodeset" I set "GRUB_GFXPAYLOAD_LINUX = text". Also I only have the DisplayLink monitor configured in my xorg.conf file. At this point I'm using the open radeon driver, although I used the proprietary ati driver before. I'm not sure if I'm having a problem with: - X configuration - Graphics driver - DisplayLink driver - Unity - LightDM - Compiz - Or something else The resolution of the monitor is 800x480, 16bit. I tried setting a larger virtual resolution of 1200x720 (because the real resolution is lower than the recommended resolution), but it causes Ubuntu to boot into low graphics mode. When I get home I'm going to install the fglrx driver and see if it enables virtual resolutions, which may further enable my window manager to function properly.

  • What are the boundaries between the responsibilities of a web designer and a web developer?

    - by Beofett
    I have been hired to do functional development for several web site redesigns. The company I work for has a relatively low technical level, and the previous development of the web sites were completed by a graphic designer who is self taught as far as web development is concerned. My responsibilities have extended beyond basic development, as I have been also tasked with creating the development environment, and migrating hosting from external CMS hosting to internal servers incorporating scripting languages (I opted for PHP/MySQL). I am working with the graphic designer, and he is responsible for the creative design of the web. We are running into a bit of friction over confusion between the boundaries of our respective tasks. For example, we had some differences of opinion on navigation. I was primarily concerned with ease-of-use (the majority of our userbase are not particularly web-savvy), as well as meeting W3 WAI standards (many of our users are older, and we have a higher than average proportion of users with visual impairment). His sole concern was what looked best for the website, and I felt that the direction he was pushing for caused some functional problems. I feel color choices, images, fonts, etc. are clearly his responsibility, and my expectation was that he would simply provide me with the CSS pages and style classes and IDs to use, but some elements of page layout also seem to fall more under the realm of "usability", which to me translates as near-synonymous with "functionality". I've been tasked with selecting the tools we'll use, which include frameworks, scripting languages, database design, and some open source applications (Moodle for example, and quite probably Drupal in the future). While these tools are quite customizable, working directly with some of the interfaces is beyond his familiarity with CSS, HTML, and PHP. This limits how much direct control he has over the appearance, which has lead to some discussion about the tool choices. Is there a generally accepted dividing line between the roles of a web designer and a web developer? Does his relatively inexperienced background in web technologies influence that dividing line?

  • Does waterfall require code complete before QA steps in?

    - by P.Brian.Mackey
    The process used at a certain company consists of: Create a layout according to some designs made in a web page design tool. (CSS, html) Requirements come in with "functional requirements". These consist of 100's of lines of business directions. E.G. Create a Table on page X. Column1 has numeric data. Column1 is the client code. Column2 is a string...etc. Write code to meet all functional requirements. When all code is checked in, send to QA (which is the BA that wrote the requirements) for inspection, bug finds and change requests. Punt back to developer with a list of X bugs and Y change requests. While bug finds or change requests 0 go to step 4. The agile development environments I have worked in allow, if not demand, early QA inspection and early user acceptance. So, pieces of the program can be refined and redefined before the entire application is in place. Not only that, but the process leaves little room for error or people changing their minds. Instead, those "change requests" come in at the last stage when they do the most damage. And being that a bug-fix's cost increases over time, this is a costly way to write code. I am no waterfall expert. As described, is this waterfall being mishandled in some way? How does waterfall address my concerns?

  • How do I stop someone using my domain for Spam emails?

    - by Vizioz Limited
    Hi Blog Readers,Every now and then I seem to have one of those low life Viagra sellers using my domain for spam emailing people.I have done everything I can think of to try and prevent then from doing this, but they seem to keep doing it. I just wondered if anyone out there new of a way to stop them?The headers from one of the bounce backs look like this:Return-Path: <[email protected]>Received: from rctp.telecomitalia.it (host49-133-dynamic.52-82-r.retail.telecomitalia.it[82.52.133.49]) by mx.google.com with SMTP id o8si307731weq.161.2010.07.23.05.33.53; Fri, 23 Jul 2010 05:33:59 -0700 (PDT)Received-SPF: fail (google.com: domain of [email protected] does not designate 82.52.133.49 as permitted sender) client-ip=82.52.133.49;Authentication-Results: mx.google.com; spf=hardfail (google.com: domain of [email protected] does not designate 82.52.133.49 as permitted sender) [email protected]: <[email protected]>Date: Fri, 23 Jul 2010 14:33:52 +0200From: Garnett Mckinnie <[email protected]>MIME-Version: 1.0To: NAME REMOVE <[email protected]>Subject: Where we are well established we areAs you can see from the headers, I have setup the SPF record and it is receiving a "hardfail"We are using Google Apps for our email hosting, so you'd kinda hope that they have got things pretty much secured down, so what I am missing? Or is it always going to be possible for other people to fake sending emails using another domain?

  • Central Ohio Day of .Net 2010 Slides and Files

    - by Brian Jackett
    This weekend I presented my “The Power of PowerShell + SharePoint 2007” session at the Central Ohio Day of .Net conference in Wilmington, OH this weekend.  This is the second year I’ve attended this conference, first time as a presenter.  For those unfamiliar Day of .Net conferences are a one-day conference on all things .NET organized by developers for developers.  These events are usually offered at no cost to anyone interested in .NET development.     The attendees of my session had some great questions and I hope they all got something worthwhile out of it.  Below are my slides and demo scripts (some of which I didn’t have time to demo) along with my sample profiles.  If you have any questions, comments, or feedback feel free to leave comments here or send me an email at [email protected].   Slides and Files SkyDrive link   Technology and Friends Interview Experience     On a side note, any of you familiar with one of my Sogeti co-workers in Detroit David Giard may know that he hosts a web series called Technology and Friends.  After my session David tracked me down and asked to interview me about PowerShell.  I was happy to oblige so we sat down and taped some material.  I don’t know when that interview will be going live, but look for it on www.davidgiard.com.   Conclusion     A big thanks goes out to all of the sponsors, speakers, and attendees for the Central Ohio Day of .Net conference.  Without all of them this conference couldn’t have been possible.  I had a great time at the conference and look forward to coming back next year whether that is as a speaker or attendee.       -Frog Out

  • Logical progressions through the job market

    - by Philluminati
    I'm 5 years out of a unrecognised university where I did Software Engineering. First job was VB.NET, one job was Python, Linux and Web development. I feel cast as a web developer. I'd love a role doing C but no one is interested in juniors if the applicant hasn't got 3 years of C development experience already. I've done some C and a drop of open source coding but I'll never have the confidence to convince someone I know absolutely what I'm doing. Do I just spend more and more time letting life pass me by as I sit in my room on a friday night writing a C problem "for the sake of learning more C" Basically I'm just not sure I want to continue my career if it's going to involve nothing but high level, machine abstracted, business logic and as interested as I am in low level development and enjoy reading books by Taunembaum I struggle to see how I can make the jump and I just feel life would be easier if I got a job in a cafe in Amsterdam rolling spliffs for customers. My ideal job, being a paid member of the Fedora development team seems so far away, without anyone to pay me to learn the skills to get there, and the only way would be to literally spend weeks and weeks of my life contributing code without recognition for free and without any guarentees at the end. Not that I've contributed anything at all so far. Are there any career paths that are logically set out so that jumping between roles is "correctly" incremental and where hard work and learning does eventually lead to the kind of places I might want to go? [ and also getting paid at the same time? ]

  • Wolfram is out, any alternatives? Or how to go custom?

    - by Patrick
    We were originally planning on using wolfram alpha api for a new project but unfortunately the cost was entirely way to high for what we were using it for. Essentially what we were doing is calculating the nutrition facts for food. (http://www.wolframalpha.com/input/?i=chicken+breast+with+broccoli). Before taking the step of trying to build something that may work in its place for this use case is there any open source code anywhere that can do this kind of analysis and compile the data? The hardest part in my opinion is what it has for assumptions and where it gets that data to power the calculations. Or another way to put it is, I cannot seem to wrap my head around building something that computes user input to return facts and knowledge. I know if I can convert the user input into some standardized form I can then compare that to a nutrition fact database to pull in the information I need. Does anyone know of any solutions to re-create this or APIs that can provide this kind of analysis? Thanks for any advice. I am trying to figure out if this project is dead in the water before it even starts. This kind of programming is well beyond me so I can only hope for an API, open source, or some kind of analysis engine to interpret user input when I know what kind of data they are entering (measurements and food).

  • Is my first employer expecting too much?

    - by priyank patel
    This is my first job as a programmer. I am working using the followig technologies: ASP.NET C# HTML CSS Javascript JQuery I work for a firm which develops software for small banking firms. Currently they have their software running in 100 firms. Their software is developed in Visual Fox Pro. I was hired to develop an online version of this software. I am the only developer. My boss is another developer, the only other developer in the firm. Therefore, my employer has a total of two developers. My boss does not have any experience with .NET development. I have been working on this project for 8 months. The progress is there, but has been very slow. I try my best to do what my boss asks. But the project just seems too ambitious for me. The company has not done have any planning for the project. They just ask me to develop what their older software provides. So I have to deal with front end, back end, review code, design architecture, and more. I have decided to give my best. I try a lot. But the project sometimes just seems to be overwhelming. Question: Is it normal for a beginner programmer to be in this place? Are my employers just expecting too much of a new programmer? As a programmer, am I lacking skills one needs to deal with this? I always feel the need to work in at least a small team, if not big one. I am just not able judge my condition. Also I am paid very low salary. I do work on Saturday as well. Please, help to clarify my judgment. Any suggestions are welcome.

  • Lexmark X5650 doesn't print (scanning works)

    - by unor
    I want to use a Lexmark X5650 under Ubuntu. When I connect it via USB, Ubuntu recognizes the device, but can't find a driver. On the Lexmark support site, you can select "Unix/Linux" and then "Ubuntu 9.04", "9.10", "10.04" and "10.10". However, all versions lead to the same driver: lexmark-08z-series-driver-1.0-1.i386.deb.sh.tar.gz (Last updated: 2012-04-13). While installing this driver, the installer asks me to connect the device. As soon as I connect it via USB, Ubuntu now adds the printer automatically. So after the installation completed, I had 2 printers set up. But I can't print anything (I tried it with both printer configurations). Scanning works fine, though. So I guess the driver installation and the device connection are successful. When I try to print something, the print job is listed in the printing queue, but nothing happens. After some time, I get an error message which starts a debug wizard, but in the end it reads something like "Sorry, couldn't find the reason". I had several different error messages (unfortunately, I didn't record them), one was approximately like "printer cannot communicate with computer". Another said that my color ink was low (which is true, but black is full). Another said there was an input/output error. I tried it with Ubuntu 11.10. Because I read that some people had success with 10.04., I installed it in QEMU and installed the driver there, too. Same problem, though. I'd like to upgrade to 12.04, if it should work there for any reason, but I read that for some people this printer stopped working in 12.04 :/ So, it would be best if the printer would work in 12.04. If that's not possible, I'd be fine with starting a QEMU virtual machine with any GNU/Linux distribution that works with my printer.

  • Rotating object along bezier curve: not rotating enough?

    - by Paul
    I tried to follow the instructions from the threads on the forum (Cocos2d rotating sprite while moving with CCBezierBy) with Unity, in order to rotate my object as it moves along a bezier curve. But it does not rotate enough, the angle is too low, it goes up to 6 instead of 90 for example, as you can see on this image (the y eulerAngle is at 6, I would expect it to be around 90 with this curve) : Would you know why it does this? And how to make the rotation toward the next point? Here is the code (in c# with Unity) : (I am comparing x and z to get the angle, and adding the angle to eulerAngles.y so that it rotates around the y axis) void Update () { if ( Input.GetKey("d") ) start = true; if ( start ){ myTime = Time.time; start = false; } float theTime = (Time.time - myTime) *0.5f; if ( theTime < 1 ) { car.position = Spline.Interp( myArray, theTime );//creates the bezier curve counterBezier += Time.deltaTime; //compare 2 positions after 0.1f if ( counterBezier > 0.1f ){ counterBezier = 0; cbDone = false; newpos = car.position; float angle = Mathf.Atan2(newpos.z - oldpos.z, newpos.x - oldpos.x); angle += car.eulerAngles.y; car.eulerAngles = new Vector3(0,angle,0); } else if ( counterBezier > 0 && !cbDone ){ oldpos = car.position; cbDone = true; } Thanks

  • Partner Webcast: Implementing on SOA - A Hands-On Technology Demonstration

    - by Thanos
    Service Oriented Architecture enables organizations to operate more efficiently and react faster to opportunities. How? By helping you create a flexible application architecture that supports greater business agility. You decide how quickly you want to move. You can start by implementing an application integration platform. Then, you can evolve your environment gradually by introducing business process management, business rules, governance and event processing. This unified but flexible approach also allows you to maximize the long-term cost reduction benefits of SOA and cloud-based applications. In this session, you dive into SOA Suite and you will see the usage of some advanced features. The topics covered range from adapters, automatic and custom business process correlation through service routing, rule based and manual decisions and to error handling, compensations and extending SOA Suite with your own Java code.

  • Running Non-profit Web Applications on Cloud/Dedicated Hosting [closed]

    - by cillosis
    Possible Duplicate: How to find web hosting that meets my requirements? I often times build web applications purely because I enjoy it. I like building useful tools or open source applications that don't come with a price tag. That being said, many of these applications can be quite complex requiring services beyond shared hosting (ex. specific PHP extensions). This leaves me with two options: Make the web application less complex and run on shared hosting. Fork out money for cloud or dedicated/VPS hosting. Considering the application is free (I don't make money off of it intentionally), the money for hosting comes out of my own pocket. I know I am not alone in this sticky situation. So the question is, what are the hosting options that provide more advanced features such as shell access via SSH, ability to install specific software/extensions (ex. if I wish to use a NoSQL DB such as Redis, MongoDB, or Cassandra), etc., at a free or low price point? I know free usually equates to bad/unreliable hosting -- but it's not always the case. There are a couple providers with free plans I know of: Amazon EC2 - Free micro-instance for 1 year AppHarbor - Cloud based .NET web application hosting w/ free plan. What else is available for hosting of non-profit applications?

  • Transient VO : Powerful J2EE Design Pattern

    - by Vijay Mohan
    We had a use-case wherein, the communication has to happen between regions residing under differenet taskfows. Essentially, they had a common set of parameters to be used. Initially, we resorted to the  use of pageFlowScope variables, but they are tightly coupled with the individual task flows. So, how the communication has to happen..?Some of the alternatives that we brainstormed into are - 1.usage of adf contextual event - This is a powerful feature indeed for such use-cases, but there is a considerable cost involved with it. So, before resorting to it, you have to make sure that you have good enough reason to use it.It actually does a server roundtrip and also the issue of an event and listening part to it is also something which requires your attention !!2.Use a transientVO with shared data control scope - with shared data control scope, the transient VO rows would be persistent across the task flows in your application. All you have to do is to create the attributes in the transientVO(prefereably with the same names - for the ease of conversion) and create some utility methods in VOImpl for creating row, updating row and deleting a row. You also have to make sure that the vo row is initialized per http request( this you can do in a bookmark method of your index.jspx - residing in adfc-config.xml), else the ui fields binded to the transient vo attributes won't render in UI.Hope, this helps and this should be a common use-case across apps.

  • Input handling between game loops

    - by user48023
    This may be obvious and trivial for you but as I am a newbie in programming I come with a specific question. I have three loops in my game engine which are input-loop, update-loop and render-loop. Update-loop is set to 10 ticks per second with a fixed timestep, render-loop is capped at around 60 fps and the input-loop runs as fast as possible. I am using one of the Javascript frameworks which provide such things but it doesn't really matter. Let's say I am rendering a tile map and the view of which elements are rendered depends on camera-like movement variables which are modified during key pressing. This is only about camera/viewport and rendering, no game physics involved here. And now, how can I handle input events among these loops to keep consistent engine reaction? Am I supposed to read the current variable modified with input and do some needed calculations in a update-loop and share the result so it could be interpolated in a render-loop? Or read the input effect directly inside the render-loop and put needed calculations inside? I thought interpreting user input inside an update-loop with a low tick rate would be inaccurate and kind of unresponsive while rendering with interpolation in the final view. How it is done properly in games overall?
