  • Workflow: Deploy Oracle Solaris 11 Zones

    - by Owen Allen
    One of the new workflows that we've introduced, which is a pretty good example of what workflows can do for you, is the Deploy Oracle Solaris 11 Zones workflow. This workflow was designed to show you everything you need to do in order to create and manage an environment with zones. It tells you what roles are needed, and it shows you the process using this image: The left side shows you the prerequisites for deploying Oracle Solaris 11 Zones - you need to have Ops Center configured on Oracle Solaris 11, have your libraries set up, and have your hardware ready to go. Once you've done that, you can begin the workflow. If you haven't provisioned Oracle Solaris 11, you do so, then create one or more zones, and create a server pool for those zones. Each one of these steps has an existing How-To, which walks you through the process in detail, and the final step of the workflow directs you to the next workflow that you're likely to be interested in - in this case, the Operating Zones workflow.

  • Web Developer interview questions

    - by Baba
    I read an article today that listed some basic questions about web development: Describe how POST data was submitted to a server by a browser. Explain a number of HTTP status codes (except maybe 404 and 500). Explain SOLID or name a design pattern. Explain ways to improve a page load speed or user experience. The author says "if you can’t answer the questions above there are a lot of people who wouldn’t think of you as a Senior Web Developer." My questions are: How relevant are these questions in respect to real life web programming and scalability? How true is that statement? In other words, do you consider this knowledge a requirement to be considered a Senior Web Developer? I was able to answer all the questions, too easily it seemed, so I'm wondering whether it is effective to use these or similar questions to screen developers rather than asking them to write sample code.

  • Linux installation on Acer Aspire One D270

    - by ronnie
    I was planning to buy Acer Aspire One D270 within a few days and as everybody installs linux on their netbook I was also planning to do that. Now, my question is how is Acer's hardware compatibility with linux and specifically in respect to the new Acer Aspire One D270. Has anybody tried installing linux on these new netbooks. It will be a great help if a D270 user can share his/her experience with linux usage. I read on some forums that there is some linux driver issue with Intel GMA 3600 and that people are not able to adjust their brightness. So, as I am a linux noob is this a major issue or not. Specs: RAM : 2Gb DDR3 Processor: Intel N2600(Cedar Trail) Graphics: Intel GMA 3600 HardDisk: 320Gb 5400 rpm

  • What is the best way to learn how to develop drivers?

    - by Kenneth
    At some point in my career I would definitely like to get involved in some embedded programming. I was thinking that starting out with developing some drivers would be a good place to develop my abilities in the regard. I'm open to doing so on either windows or linux platform (eventually will want to probably attempt both). What tools would you recommend that I look into to get me started on this project? Any other resources that you have found to be helpful (i.e. books, websites, programs, etc)? Any advice/recommendations? Thanks!

  • Learning c++ by contributing to open source projects

    - by user1189880
    I have some general programming experience with a few different languages, my most skilled being php. I want to spend a lot of time over the next year learning c++ in much more depth and then eventually get to a good enough level to find a job as a junior developer working in c++. I really struggle to find things to develop as toy programs so want to contribute to an open source project in c++ to get really stuck in to. But the projects I see on github in c++ are very large and will require a lot of knowlege to even get started. Are there any smaller projects that I can contribute to or are there any other good ideas for learning c++ from a practical level.

  • Why isn't Java more widely used for game development?

    - by Anto
    I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

  • Developing payment gateway.

    - by kmaxat
    Hello, I have an idea of developing internet payment gateway similar to PayPal or Webmoney. Since i'm only sophomore at Computer Science, and i've only taken intermediate programming classes, i've no idea where to search for general information about this topic. I do understand that this kind of project is CLEARLY too much to handle for sophomore. Since, it's forum for Pro Webmasters, and probably some of you can point direction of study. What book/source/article would you suggest to read to understand fundamentals of internet payment? What book/source/article would you suggest to read to understand fundamentals internet security? What language is most commonly used for developing payment security of website? I appreciate any help. Thank you.

  • My integer overfloweth

    - by darcy
    While certain classes like java.lang.Integer and java.lang.Math have been in the platform since the beginning, that doesn't mean there aren't more enhancements to be made in such places! For example, earlier in JDK 8, library support was added for unsigned integer arithmetic. More recently, my colleague Roger Riggs pushed a changeset to support integer overflow, that is, to provide methods which throw an ArithmeticException on overflow instead of returning a wrapped result. Besides being helpful for various programming tasks in Java, methods like the those for integer overflow can be used to implement runtimes supporting other languages, as has been requested at a past JVM language summit. This year's language summit is coming up in July and I hope to get some additional suggestions there for helpful library additions as part of the general discussions of the JVM and Java libraries as a platform.

  • ubuntu integrated graphics suspend + hybrid graphics

    - by kapad
    My laptop uses a hybrid graphics hardware. Using the vgaswitcheroo I am able to power off either card and switch between them correctly. The issue is that the system wakes up/resumes from suspend correctly only when using the discrete graphics, or atleast the discrete graphics must be powered on even if the display is connected to the onboard intel card. Has anyone faced this issues? Is there any workaround? I only want to use the integrated card and not the discrete amd card. System Info Intel HD 3000 ATI mobility radeon HD 7600M Ubuntu 12.10

  • When there's no TCO, when to worry about blowing the stack?

    - by Cedric Martin
    Every single time there's a discussion about a new programming language targetting the JVM, there are inevitably people saying things like: "The JVM doesn't support tail-call optimization, so I predict lots of exploding stacks" There are thousands of variations on that theme. Now I know that some language, like Clojure for example, have a special recur construct that you can use. What I don't understand is: how serious is the lack of tail-call optimization? When should I worry about it? My main source of confusion probably comes from the fact that Java is one of the most succesful languages ever and quite a few of the JVM languages seems to be doing fairly well. How is that possible if the lack of TCO is really of any concern?

  • Performance tracking/monitoring in games

    - by vitaliy kotik
    Let's say I have an online game with a downloadable client / browser plugin. I want to track performance of my software and automatically send summary to the server. Let it be fps, latency, load time, physics step calc. time, whatever... I also want tools to perform data analysis: per session stats, per hardware stats, avgs, totals, diagrams, etc. So that I could see what are the real world hotspots / bottlenecks. Is there any common out-of-the-box / SaS solution?

  • What do you do when you realize your job requires you to do something out of your depth?

    - by Billy ONeal
    For a large software project recently, I was really out of my depth. And I did actually know this; and that the only reason I was employed was mostly a lack of other qualified candidates. The job was to build a large application on top of PHP/MySQL, a system I had little experience with. (I did advise the employer of this beforehand -- I've been spoiled by C# ASP.NET/MVC and MSSQL Server) The main reason I applied was location, location, location -- on campus jobs which actually have any programming component are relatively rare. For almost a year and a half I've slogged through this, and I think I can say I know (at least somewhat) what I'm doing now. I've made some mistakes, torn out some hair, and moved on. (I'm still working on this system nowadays, but I no longer feel completely lost) In the future though, I'd like to keep my personal and professional self a little healthier than what occurred in this case. So I'm curious -- what's the best way to handle a situation like this?

  • Java EE at JavaOne - A Few Picks from a Very Rich Line-up

    - by Janice J. Heiss
    A rich and diverse set of sessions cast a spotlight on Java EE at this year’s JavaOne, ranging from the popular Web Framework Smackdown, to Java EE 6 and Spring, to sessions exploring Java EE 7, and one on the implications of HTML5. Some of the world’s best EE architects and developers will be sharing their insight and expertise. If only I could be at ten places at once!BOF4149 - Web Framework Smackdown 2012    Markus Eisele - Principal IT Architect, msg systems ag    Graeme Rocher - Senior Staff Engineer, VMware    James Ward - Developer Evangelist, Heroku    Ed Burns - Consulting Member of Technical Staff, Oracle    Santiago Pericasgeertsen - Software Engineer, Oracle* Monday, Oct 1, 8:30 PM - 9:15 PM - Parc 55 - Cyril Magnin II/III Much has changed since the first Web framework smackdown, at JavaOne 2005. Or has it? The 2012 edition of this popular panel discussion surveys the current landscape of Web UI frameworks for the Java platform. The 2005 edition featured JSF, Webwork, Struts, Tapestry, and Wicket. The 2012 edition features representatives of the current crop of frameworks, with a special emphasis on frameworks that leverage HTML5 and thin-server architecture. Java Champion Markus Eisele leads the lively discussion with panelists James Ward (Play), Graeme Rocher (Grails), Edward Burns (JSF) and Santiago Pericasgeertsen (Avatar).CON6430 - Java EE and Spring Framework Panel Discussion    Richard Hightower - Developer, InfoQ    Bert Ertman - Fellow, Luminis    Gordon Dickens - Technical Architect, IT101, Inc.    Chris Beams - Senior Technical Staff, VMware    Arun Gupta - Technology Evangelist, Oracle* Tuesday, Oct 2, 10:00 AM - 11:00 AM - Parc 55 - Cyril Magnin II/III In the age of Java EE 6 and Spring 3, enterprise Java developers have many architectural choices, including Java EE 6 and Spring, but which one is right for your project? Many of us have heard the debate and seen the flame wars—it’s a topic with passionate community members, and it’s a vibrant debate. If you are looking for some level-headed discussion, grounded in real experience, by developers who have tried both, then come join this discussion. InfoQ’s Java editors moderate the discussion, and they are joined by independent consultants and representatives from both Java EE and VMWare/SpringSource.BOF4213 - Meet the Java EE 7 Specification Leads   Linda Demichiel - Consulting Member of Technical Staff, Oracle   Bill Shannon - Architect, Oracle* Tuesday, Oct 2, 5:30 PM - 6:15 PM – Parc 55 - Cyril Magnin II/III This is your chance to meet face-to-face with the engineers who are developing the next version of the Java EE platform. In this session, the specification leads for the leading technologies that are part of the Java EE 7 platform discuss new and upcoming features and answer your questions. Come prepared with your questions, your feedback, and your suggestions for new features in Java EE 7 and beyond.CON10656 - JavaEE.Next(): Java EE 7, 8, and Beyond    Ian Robinson - IBM Distinguished Engineer, IBM    Mark Little - JBoss CTO, NA    Scott Ferguson - Developer, Caucho Technology    Cameron Purdy - VP Development, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin II/IIIIn this session, hear from a distinguished panel of industry and open source luminaries regarding where they believe the Java EE community is headed, starting with Java EE 7. The focus of Java EE 7 and 8 is mostly on the cloud, specifically aiming to bring platform as a service (PaaS) providers and application developers together so that portable applications can be deployed on any cloud infrastructure and reap all its benefits in terms of scalability, elasticity, multitenancy, and so on. Most importantly, Java EE will leverage the modularization work in the underlying Java SE platform. Java EE will, of course, also update itself for trends such as HTML5, caching, NoSQL, ployglot programming, map/reduce, JSON, REST, and improvements to existing core APIs.CON7001 - HTML5 WebSocket and Java    Danny Coward - Java, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin IThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform.

  • How do you react to non-programmers with ideas of 'The Next Big Thing' ?

    - by jiceo
    Recently and quite often, people with no programming background come and say they have this great idea that can be the next big thing and that the idea(s) is worth a fortune by itself. Then as they know I'm a programmer, they ask me if I'm willing to "code it up" for them or find someone willing to do it for next to nothing. Judging from the enthusiasm, it's like they're drunk on their idea and that that by itself is the most important thing, but they just need a programmer. My response to them, depending on my mood and their general attitude towards what we do, is something along the lines of: "Having the core of an idea is one thing. Developing it to the point that it becomes a platform that changes the world in which it lives is another, and you're going to be willing to pay proportionately to how big you think your idea is worth." Have you been approached by these business type entrepreneurs (with no technical/developer's knowledge) with such a proposal and how do you react to them?

  • Game server for an android/iOS turn-based board-game

    - by Cyril
    I am currently programming an iPhone game and I would like to create an online multiplayer mode. In the future, this app will be port to Android devices, so I was wondering how to create the game-server? First at all, which language should I choose? How to make a server able to communicate both with programs written in objective-c and Java? Then, how to effectively do it? Is it good if I open a socket by client (there'll be 2)? What kind of information should I send to the server? to the clients?

  • Executing Shell Commands - PHP or Python?

    - by chadpeppers
    I know basically two languages: Python and PHP. I am primarily a Drupal developer. I have a great idea in creating a command line program that will help some of the mundane tasks and bring my efficiency up quite a bit. The concept is that of a complete console program, almost like the days when I learned C++ using stdin/out. I want to use this came concept but for this program. I am going to be executing shell commands (mainly drush commands, if you are familiar with drush its drupals way of doing tasks like installing drupal, clearing cache, and other things). I am also wanting to do a database and save/execute through multiple objects and site profiles. My general question is this. Which language would be better suited to handle command line code? Drupal is written in PHP so I am leaned more towards that,but I know python seems to handle console programming a bit easier. Any help would be great!
