• Working with Lightweight User Interface Toolkit (LWUIT) 1.4

  - by janice.heiss(at)oracle.com

  Vikram Goyal's informative and practical article, "Working with Lightweight User Interface Toolkit (LWUIT) 1.4," shows developers how to best take advantage of LWUIT 1.4. LWUIT is a user interface library designed to bring uniformity and cross mobile interface functionality to applications developed using Java Platform, Micro Edition (Java ME). Version 1.4 offers support for XHTML, multi-line text fields, and customization to the virtual keyboard.Goyal notes in the article that, "Perhaps the most important feature of this release is the ability for LWUIT to support XHTML. Specifically, it now supports XHTML MP (Mobile Platform) 1.0, a version of XHTML designed for mobile phones. To be even more specific, it now supports CSS styling for the HTMLComponent within the LWUIT library through Wireless Application Protocol CSS (WCSS)." Read the entire article here.

• Performance cost of running Ubuntu from external hard drive

  - by dandan78

  A friend just complained to me about Ubuntu being slow. Although I've noticed a certain lack of snappiness with Linux vs Windows in the past, I really can't say I've had much to grumble about with the recent distributions of Ubuntu. That said, his objections seem much worse than the ones I used to have and I know that his current setup is significantly more powerful than my laptop. And then it turned out he is running Ubuntu off an external HDD hooked up via USB2.0. The HD enclosure is USB3.0 but apparently he can't manage to get it to boot on USB3.0 so he switched to one of the USB2.0 ports or whatever and that works, albeit not very well. Now I would expect USB to add some overhead to communication between the computer and the HDD; SATA is after all designed to get the maximum out of a hard drive, whereas USB is, well, universal. What are your expreriences with booting off external HDDs? Edit: Does anybody know just how much of a slowdown can be expected?

  On HTML5 Boilerplate they use this code for jQuery: <!-- Load jQuery with a protocol relative URL; fall back to local if offline --> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></scrip> <script>window.jQuery || document.write('<script src="js/libs/jquery-1.7.2.min.js"><\/script>')</script> The question is simple, what's more readable: if (!jQuery) document.write( -local jQuery- ); or window.jQuery || document.write( -local jQuery- );

• Time/duration handling in strategic game

  - by borg

  I'm considering developing a space opera game, having already done some game design. Technically, though, I'm coming from a business applications background. Hence I don't really know how I should handle time and duration. Let's state the matter clearly: what if something is bound to happen in 5 hours and on which other events depend. For example the arrival of some space ship in some system where some defense systems are present, hence a fight would start. Should I use some kind of scheduler (like Quartz in my java land) to trigger the corresponding event when due (I plan to use events for communication)? Something else?

• Cowboy Agile?

  - by Robert May

  In a previous post, I outlined the rules of Scrum.  This post details one of those rules. I’ve often heard similar phrases around Scrum that clue me in to someone who doesn’t understand Scrum.  The phrases go something like this: “We don’t do Agile because the idea of letting people just do whatever they want is wrong.  We believe in a more structured approach.” (i.e. Work is Prison, and I’m the Warden!) “I love Agile.  Agile lets us do whatever we want!” (Cowboy Agile?) “We’re Agile, but we use a process that I’ve created.” (Cowboy Agile?) All of those phrases have one thing in common:  The assumption that Agile, and I mean Scrum, lets you do whatever you want.  This is simply not true. Executing Scrum properly requires more dedication, rigor, and diligence than happens in most traditional development methods. Scrum and Waterfall Compared Since Scrum and Waterfall are two of the most commonly used methodologies, a little bit of contrasting and comparing is in order. Waterfall Scrum A project manager defines all tasks and then manages the tasks that team members are working on. The team members define the tasks and estimates of the stories for the current iteration.  Any team member may work on any task in the iteration. Usually only a few milestones that need to be met, the milestones are measured in months, and these milestones are expected to be missed.  Little work is ever done to improve estimates and poor estimators can hide behind high estimates. Stories must be delivered every iteration, milestones are measured in hours, and the team is expected to figure out why their estimates were wrong, even when they were under.  Repeated misses can get the entire team fired. Partially completed work is normal. Partially completed work doesn’t count. Nobody knows the task you’re working on. Everyone knows what you’re working on, whether or not you’re making progress and how much longer you think its going to take, in hours. Little requirement to show working code.  Prototypes are ok. Working code must be shown each iteration.  No smoke and mirrors allowed.  Testing is done in lengthy cycles at the end of development.  Developers aren’t held accountable. Testing is part of the team.  If the testers don’t accept the story as complete, the team can’t count it.  Complete means that the story’s functionality works as designed.  The team can’t have any open defects on the story. Velocity is rarely truly measured and difficult to evaluate. Velocity is integral to the process and can be seen at a glance and everyone in the company knows what it is. A business analyst writes requirements.  Designers mock up screens.  Developers hide behind “I did it just like the spec doc told me to and made the screen exactly like the picture” Developers are expected to collaborate in real time.  If a design is bad or lacks needed details, the developers are required to get it right in the iteration, because all software must be functional.  Designers and Business Analysts are part of the team and must do their work in iterations slightly ahead of the developers. Upper Management is often surprised.  “You told me things were going well two months ago!” Management receives updates at the end of every iteration showing them exactly what the team did and how that compares to what' is remaining in the backlog.  Managers know every iteration what their money is buying. Status meetings are rare or don’t occur.  Email is a primary form of communication. Teams coordinate every single day with each other and use other high bandwidth communication channels to make sure they’re making progress.  Email is used only as a last resort.  Instead, team members stand up, walk to each other, and talk, face to face.  If that’s not possible, they pick up the phone. IF someone asks what happened, its at the end of a lengthy development cycle measured in months, and nobody really knows why it happened. Someone asks what happened every iteration.  The team talks about what happened, and then adapts to make sure that what happened either never happens again or happens every time.   That’s probably enough for now.  As you can see, a lot is required of Scrum teams! One of the key differences in Scrum is that the burden for many activities is shifted to a group of people who share responsibility, instead of a single person having responsibility.  This is a very good thing, since small groups usually come up with better and more insightful work than single individuals.  This shift also results in better velocity.  Team members can take vacations and the rest of the team simply picks up the slack.  With Waterfall, if a key team member takes a vacation, delays can ensue. Scrum requires much more out of every team member and as a result, Scrum teams outperform non-Scrum teams working 60 hour weeks. Recommended Reading Everyone considering Scrum should read Mike Cohn’s excellent book, User Stories Applied. Technorati Tags: Agile,Scrum,Waterfall

• Licensing Options for a dead project

  - by Russell Durham

  I'm currently working on a project where the original author informally told me that he didn't want to publish the source. Since then, the original author has gone leaving me to be the sole developer on the project. I've tried to contact him several times about making the project open source so that I can have other developers assist me but he is not responding to any communications. I'm not planning on trying to make money of the software, I just want a general license that allows me to put the code on GitHub or BitBucket so that other people in the community can assist me with the development. Can I do this since he is gone and not responding to any form of communication? Is there a time period I need to wait? I know what I asking for is legal advice, I just have no idea where to start looking to find the answer so I decided to start here.

• Looking for reading material on application architecture with web UI

  - by toong

  I'm looking for articles (or other reading material) on the topic of fat client applications with a web UI layer. Open-source projects that use this architecture would be very interesting too. Such an application would embed one (or more) browser-window(s) (chromiumembedded for example). You would need bidirectional communication between your web-UI and your domain model/services. I think this allows quick prototyping the UI, a clean separation between logic and UI and potentially easier portability across platforms (compared to WinForms for example). But that is just my view, I was looking for the view of people who have been on that road. An example of an application using a web-ui layer is Light Table. Unfortunately it is not open source (at this point?).

• Ubutu 14.04 triple screen, third screen black and X cursor

  - by Horse

  I am having some issues getting my third screen working properly. I had triple screens working fine on 12.04, using 2 nvidia cards. Did a fresh install of 14.04 and having no end of problems getting it working. It either will just be disabled, or the screen is black with the cursor as an X. I can only enable it from the nvidia server settings tool. The Ubuntu native display settings won't even show the 3rd screen. I tried copying the xorg.conf from my old install, which upon restarting X worked fine on the login screen, but then it just sat there after I logged in and didn’t do anything (mouse was still working). I am using gnome-session-fallback instead of unity if that makes any difference. Still having these issues if I try unity though. How do I get my 3rd screen working and displaying a desktop?

• Server Side Developer Prerequisites

  - by Jking

  I am new to server side development and am currently learning node.js. What sort of networking information should I be familiar with to allow for a smooth learning curve with server side development. Could anyone provide resources pertaining to the information required to get into server programming? To give you a better idea of my standpoint: I do not know how a server interacts with a database [Q: How does a NoSQL database, or database in general, communicate with a server?] I am unsure of how a web stack works [Q: I have heard of LAMP but do not know how Apache, MySQL, and PHP interact. Hopefully this applies to other stacks as well. How do the components of a stack work together? Also, is a MEAN stack an alternative, or is it completely irrelevant to this] I have trivial knowledge of internet protocol [however extremely inefficient][Q: What resources are beneficial when learning about networking, and how much/what knowledge should I acquire to program on the server side] I am unsure of what I am unsure of concerning networking information necessary to start development Information on how the client-server model works would be greatly appreciated

• Oracle VM RAC template - what it took

  - by wcoekaer

  In my previous posting I introduced the latest Oracle Real Application Cluster / Oracle VM template. I mentioned how easy it is to deploy a complete Oracle RAC cluster with Oracle VM. In fact, you don't need any prior knowledge at all to get a complete production-ready setup going. Here is an example... I built a 4 node RAC cluster, completely configured in just over 40 minutes - starting from import template into Oracle VM, create VMs to fully up and running Oracle RAC. And what was needed? 1 textfile with some hostnames and ip addresses and deploycluster.py. The setup is a 4 node cluster where each VM has 8GB of RAM and 4 vCPUs. The shared ASM storage in this case is 100GB, 5 x 20GB volumes. The VM names are racovm.0-racovm.3. The deploycluster script starts the VMs, verifies the configuration and sends the database cluster configuration info through Oracle VM Manager to the 4 node VMs. Once the VMs are up and running, the first VM starts the actual Oracle RAC setup inside and talks to the 3 other VMs. I did not log into any VM until after everything was completed. In fact, I connected to the database remotely before logging in at all. # ./deploycluster.py -u admin -H localhost --vms racovm.0,racovm.1,racovm.2,racovm.3 --netconfig ./netconfig.ini Oracle RAC OneCommand (v1.1.0) for Oracle VM - deploy cluster - (c) 2011-2012 Oracle Corporation (com: 26700:v1.1.0, lib: 126247:v1.1.0, var: 1100:v1.1.0) - v2.4.3 - wopr8.wimmekes.net (x86_64) Invoked as root at Sat Jun 2 17:31:29 2012 (size: 37500, mtime: Wed May 16 00:13:19 2012) Using: ./deploycluster.py -u admin -H localhost --vms racovm.0,racovm.1,racovm.2,racovm.3 --netconfig ./netconfig.ini INFO: Login password to Oracle VM Manager not supplied on command line or environment (DEPLOYCLUSTER_MGR_PASSWORD), prompting...

• modifying openssl library code

  - by Nouar Ismail

  I am ordered to check the availability to customize an encryption algorithm the IPsec protocol use in Ubuntu, if anyone have any suggestion about this point?. I've read that the encryption operation occur in libcrypto in openssl. when I tried to compile and install OpenSSL from source ..I had everything ok with the installation, but when to check the version installed on the system, with "dpkg -s openssl", it didn't seem that it's the version i had already installed, maybe it had been installed successfully, but the question is: would it be the version the system use for encryption operations? would it overwrite the old version? and would my changes in code have effects ? any help please? thank you in advance.

• What to choose API based server or Socket based server for data driven application

  - by Imdad

  I am working on a project which has a Desktop Application for MAC/COCOA, a native application for iPhone another native application in iPad. All the application do almost same thing. The applications are data driven applications. Every communication to server is made via a restful API developed in PHP. When a user logs in a lot of data is fetched from server. And to remain in sync with server pooling is done. As there are lot of data to pool it makes application slower and un-reliable. A possible solution that comes into my mind is to use Socket based server. My question is that will it reasonably improve the performance? And which technology (of sockets) will be good as a server side solution for data driven application? I have heard a lot about Node.js. Please give your suggestions.

• How to obtain a S/MIME certificate for e-mail encryption?

  - by mghg

  There are parties, e.g. enterprises, that uses S/MIME certificates for e-mail encryption. To my understanding Thunderbird has support by default for S/MIME. But I have not found a way to obtain a personal S/MIME certificate to be used on a Ubuntu system. Thus my question: How to obtain a S/MIME certificate for e-mail encryption? Moreover, is it correct to believe that Thunderbird has support by default for S/MIME? I am fully aware of PGP, GnuPG and OpenPGP for public-key cryptography and secure e-mail communication. In my opinion, it is very useful that OpenPGP is installed by default on Ubuntu systems. But I need to find a method to communicate securely with parties that use S/MIME and not PGP/GnuPG/OpenPGP.

• How these files can be accessed?

  - by harsh.singla

  The files can be accessed from every artifact, such as .bpel, .mplan, .task, .xsl, .wsdl etc., of the composite. 'oramds' protocol is used to access these files. You need to setup your adf-config.xml file in your dev environment or Jdeveloper to access these files from MDS. Here is the sample adf-config.xml. xmlns:sec="http://xmlns.oracle.com/adf/security/config" name="jdbc-url"/ name="metadata-path"/ credentialStoreLocation="../../src/META-INF/jps-config.xml"/ This adf-config.xml is located in directory named .adf/META-INF, which is in the application home of your project. Application home is the directory where .jws file of you application exists. Other than setting this file, you need not make any other changes in your project or composite to access MDS. After setting this up, you can create a new SOA-MDS connection in your Jdev. This enables you to have a resource pallet in which you can browse and choose the required file from MDS.

Microsoft vient à la fois de confirmer l'existence d'une tablette Courier, et d'en annoncer la mort. Voici donc un rival de moins pour l'iPad d'Apple. C'est Frank Shaw, chargé de communication pour Microsoft, qui a fait -il y a à peine quelques heures- la déclaration suivante aux médias américains : «A tout moment, de nouvelles idées sont expérimentées, testées et incubées. C'est dans l'ADN de Microsoft. Le projet «Courier» en est un exemple. Sa technologie sera évaluée pour un usage futur, mais nous ne prévoyon...
