• How does rc job work / order of (contradicting) "start on ..." and "stop on ..." stanzas

  - by Binarus

  Hi, I just can't understand how Upstart's rc job definition in Natty 11.04 works. To illustrate the problem, here is the definition (empty lines and comments are left out): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL Let's suppose we currently are in runlevel 2 and the rc job is stopped (that is exactly the situation after booting my box and logging in via SSH). Now, let's assume that the system switches to runlevel 3, for example due to a command like "telinit 3" given by root. What will happen to the rc job? Obviously, the rc job will be started since it is currently stopped and the event runlevel 3 is matching the start events. But from now on, things are unclear to me: According to the manual $RUNLEVEL evaluates to the new runlevel when the job is started (that means 3 in our example). Therefore, the next stanza "stop on runlevel [!$RUNLEVEL]" translates to "stop on runlevel [!3]"; that means we have a first stanza which will trigger the job, but the second stanza will never stop the job and seems to be useless. Since I know that the Ubuntu / Upstart people won't do useless things, I must be heavily misunderstanding something. I would be grateful for any explanation. While trying to understand this, an additional question came to my mind. If I had contradicting start and stop triggers, for example start on foo stop on foo what would happen? I swear I never will do that, but I am nevertheless very interested in how Upstart handles that on the theoretical level. Thank you very much! Editing the question as a reaction on geekosaur's first answer: I can see the parallelism, but it is not that easy (at least, not to me). Let's assume the job aurrently is still running, and a new runlevel event comes in (of course, the new runlevel is different from the current one). Then, the following should happen: 1) The job is single instance. That means that "start on ..." won't be triggered since the job is currently running; $RUNLEVEL is not touched. 2) "stop on ..." will be triggered since the new runlevel is different from $RUNLEVEL, so the job will be aborted. 3) Now, the job is stopped and waiting. I can't see how it is restarted with the new runlevel. AFAIK, initctl emits events only once, so "start on ..." won't be triggered and the new runlevel won't be entered. I know that I still misunderstanding something, and I am grateful for explanations. Thank you very much!

• Failed 12.04 installation

  - by Rob Sayer

  I tried installing Ubuntu 12.04 today. Not an upgrade, a new installation. It didn't work. My computer specs: Computer: Compaq presario CQ-104CA OS: Windows 7 Home 64 bit CPU: AMD V140 BIOS: latest Graphics: amd m880g with ati mobility radeon hd 4250 Wireless: atheros ar9285 Internal HD:SATA I wasn't connected to the internet at the time ... I know of a number of people who have installed ubuntu unconnected and just updated later. It seemed to go normally until I got to the part where I chose to install dual boot linux/windows. Then, the screen went black and the following test appeared (I left out the [OK]'s): checking battery state starting crash report submission daemon stating cpu interrupts balancing daemon stopping system V runlevel compatibility starting configure network device security stopping configure network device security stopping cold plug devices stopping log initial device creation starting enable remaining boot-time encrypting devices starting configure network device security starting save udev log and update rules stopping save udev log and update rules stopping enable remaining boot-time encrypted block devices checking for running unattended-upgrades acpid: exiting speech-dispatcher disabled: edit /etc/default/speech-disorder At this point, the CD is ejected. Then nothing. If I press the return key, it boots Windows. I don't think that's what's supposed to happen. Thinking the cd media or dvd drive may have been faulty, I downloaded the .iso again and made a bootable USB stick, as per your instructions. This time there was no cryptic crash screen. It just booted windows. I can't find any log files it may have left. Thinking the amd64 version may have been the wrong one, I tried downloading the x86 version. Same thing, both from cd and usb drive. Note I downloaded both files twice. I doubt it was a corrupted d/l. This is supposed to be a simple, transparent install. I went to the time and trouble of looking up my devices and drivers re ubuntu beforehand, and was prepared to do some configuration, though I know someone who has the same wireless device and his worked righted out of the box. But I spent over 3 hours trying to install it with only the above to show for it.

• Games at Work Part 2: Gamification and Enterprise Applications

  - by ultan o'broin

  Gamification and Enterprise Applications In part 1 of this article, we explored why people are motivated to play games so much. Now, let's think about what that means for Oracle applications user experience. (Even the coffee is gamified. Acknowledgement @noelruane. Check out the Guardian article Dublin's Frothing with Tech Fever. Game development is big business in Ireland too.) Applying game dynamics (gamification) effectively in the enterprise applications space to reflect business objectives is now a hot user experience topic. Consider, for example, how such dynamics could solve applications users’ problems such as: Becoming familiar or expert with an application or process Building loyalty, customer satisfaction, and branding relationships Collaborating effectively and populating content in the community Completing tasks or solving problems on time Encouraging teamwork to achieve goals Improving data accuracy and completeness of entry Locating and managing the correct resources or information Managing changes and exceptions Setting and reaching targets, quotas, or objectives Games’ Incentives, Motivation, and Behavior I asked Julian Orr, Senior Usability Engineer, in the Oracle Fusion Applications CRM User Experience (UX) team for his thoughts on what potential gamification might offer Oracle Fusion Applications. Julian pointed to the powerful incentives offered by games as the starting place: “The biggest potential for gamification in enterprise apps is as an intrinsic motivator. Mechanisms include fun, social interaction, teamwork, primal wiring, adrenaline, financial, closed-loop feedback, locus of control, flow state, and so on. But we need to know what works best for a given work situation.” For example, in CRM service applications, we might look at the motivations of typical service applications users (see figure 1) and then determine how we can 'gamify' these motivations with techniques to optimize the desired work behavior for the role (see figure 2). Description of Figure 1 Description of Figure 2 Involving Our Users Online game players are skilled collaborators as well as problem solvers. Erika Webb (@erikanollwebb), Oracle Fusion Applications UX Manager, has run gamification events for Oracle, including one on collaboration and gamification in Oracle online communities that involved Oracle customers and partners. Read more... However, let’s be clear: gamifying a user interface that’s poorly designed is merely putting the lipstick of gamification on the pig of work. Gamification cannot replace good design and killer content based on understanding how applications users really work and what motivates them. So, Let the Games Begin! Gamification has tremendous potential for the enterprise application user experience. The Oracle Fusion Applications UX team is innovating fast and hard in this area, researching with our users how gamification can make work more satisfying and enterprises more productive.

• Developing for Windows CE platform?

  - by grmbl

  I'm looking in creating some applications for workers to use on the workfloor. They'll be using Psion NEO devices running Windows CE 5.0. My skillset allows for C#, PHP, ASP.Net (+ webservices). Application requirements: should connect to our ERP system running on IBM iSeries (AS400). should be run in fullscreen (effectively hiding the OS). usability touch functionality. I have tried the following: Full winform application ran through RDP session: [+] easy deployment using .rdp file. [+] application can be run on desktop environment too. [+] rdp host can easily access DB2 using IBM drivers. [+] GUI works ok on small screen. [-] environment = terminal server. (which is already under heavy use) Full winform application running on device OS: [+] environment = local. [+] responsive. [-] must use a webservice to access DB2. [-] deployment... [-] fixed platform (no desktop) Console application running on device OS: [+] environment = local. [+] very responsive. [-] must use a webservice to access DB2. [-] no fullscreen or other window options? [-] deployment... [-] fixed platform (no desktop) I'm considering creating a web application but it seems the OS comes with IE 5? I don't want to alter the OS in any way! (install other browsers etc.) I would like to have an application that's responsive, easy to deploy, fullscreen and optionally multiplatform. I have seen handheld devices using terminal (emulation?) with a console like interface. This seems to be native to the device but I'm afraid this requires modest knowledge of C++? It seems that using RDP is the way to go but, I came here for advice and look for people that have been in the same situation willing to share their experience. There does not seem to be many "best practices" on the web that could help me decide the best way of working. Greetings

• How do I prevent having to log in on 3 separate prompts every time I start my machine?

  - by JC

  Ubuntu 11.04 Natty Narwhal, Ubuntu Classic desktop Each time I start my machine, I have to log in 3 times. I spent a week in IRCFreenode#ubuntu and got nothing but condescension. I've searched on the official Ubuntu fora for similar problems, tried every recommendation, and still get 3 login screens. As a workaround, I have reset login such that I get a login screen at startup, which I'd prefer not to get since this machine is accessible by no one but me, physically. I have gone into System Preferences Passwords and Encryption Keys, set first 'Passwords: default' to 'Default' and unlocked it, and unlocked the 'Passwords: login' key, too. Next, since that changed nothing, I set 'Passwords: login' to 'Default', and checked to make sure it was still unlocked. Again, no change, still get 3 login prompts at startup. I've checked twice to insure that I am the owner of the files; I am. At the suggestion of several people in #ubuntu, I've deleted first one, then the other password key in 'Passwords and Encryption Keys'. Still get 3 login prompts. I changed from the Unity desktop to Ubuntu Classic. While that didn't fix the above problem, it is a much more elegant desktop than Unity, and I'll keep it. From what I've read, this seems to be a Seahorse issue, but beyond that, no one seems to have a solution that works. I'm lost. This shouldn't be this difficult or annoying. I'm trying to help our local Old Time music collective get their machines switched over to Ubuntu in order to save them some money which they can use to promote their DRM-free music. But from what I've seen of Ubuntu so far on my own machine, I can't really recommend that they make this switch. I hope to be proved wrong on that point. But as it stands, if I was out of town or out of country and they ran into a problem, they'd have no way of fixing it as they're all less experienced than even I am. I'm not trying to cast aspersions on Ubuntu or Linux, but it seems pretty clear that KNOWLEDGEABLE, HELPFUL support for Ubuntu is lacking barring any desire on the problem-experiencing-user's part to avoid condescension. Having worked with, and run, several non-profits over the past 20 years, I know that getting volunteers to act professionally can be like herding cats. But an organization's reputation can be denigrated by sarcastic behaviors on the part of those who serve, effectively, as its public face. Thank you all for your help and support. Now...does anyone have a solution to my problem?

• My Graduate Experience at Oracle by Mayuri Khinvasara

  - by david.talamelli

  My experience at Oracle. I still vividly remember the day, when my name was announced in the campus hiring list of Oracle at my college. I was proud of myself but at the same time, I was getting goose bumps!!! A new world had arrived before me and the anxiousness of whether I could survive it or not had gripped me. Nervous about moving into an unknown city, I came to visit Hyderabad with my father. One look at the Oracle Campus and I felt some kind of magnetism pulling me towards it. And then, I joined Oracle in June 2009, with a lot of apprehensions in my mind. The HR Rep made us really comfortable in the first week itself. I met so many new people, managers, HR folks and most importantly 20 other Campus Hires like me. Then we had our team bonding sessions, team parties etc. I didn’t realize when the transition from campus to corporate happened. And I had started loving it. The confidence the HR Reps gave us and the bonding our managers imbibed in us, made us all ready for the new life ahead. Then started the rigorous training sessions, the excitement about our new work, new cubicles, new desktops, our first business cards, our first conference call and so on. I made new friends which were now my extended family, the freedom and courage of living alone. I was enjoying all that. As I was getting totally immersed into my regular work schedule I started getting to know the innumerable Oracle products, their functionalities, implementations and realizing the brand that Oracle is. Work pressure started increasing and so did the challenges to understand and deliver. I Didn’t realize how days and soon months passed by. Then came a golden chance to visit the Oracle Headquarters in US for 45 days training in November 2009. Once again, the excitement was enormous about the counter team-mates in HQ, the trainings ahead, the US work culture and my stay there. I felt so privileged for the company I was working. Boarding an international flight for the first time and visiting famous US cities which I had just seen in movies, was now a reality. It was a totally amazing experience. Work pressure kept me really busy, with learning new things every day, the immense satisfaction of delivering something, the nightmares of debugging a mistake, only to realize how silly it was.  I was enjoying the process. Soon a year passed by. I had transformed into this corporate software professional, I couldn’t believe I could be. Today, I complete 1 year and 8 months at Oracle and continue to look forward to the enriching experience I will have here. Truly one of the Top Companies in the World. Mayuri Khinvasara

• Difference between the terms Material & Effect

  - by codey

  I'm making an effect system right now (I think, because it may be a material system... or both!). The effects system follows the common (e.g. COLLADA, DirectX) effect framework abstraction of Effects have Techniques, Techniques have Passes, Passes have States & Shader Programs. An effect, according to COLLADA, defines the equations necessary for the visual appearance of geometry and screen-space image processing. Keeping with the abstraction, effects contain techniques. Each effect can contain one or many techniques (i.e. ways to generate the effect), each of which describes a different method for rendering that effect. The technique could be relate to quality (e.g. high precision, high LOD, etc.), or in-game-situation (e.g. night/day, power-up-mode, etc.). Techniques hold a description of the textures, samplers, shaders, parameters, & passes necessary for rendering this effect using one method. Some algorithms require several passes to render the effect. Pipeline descriptions are broken into an ordered collection of Pass objects. A pass provides a static declaration of all the render states, shaders, & settings for "one rendering pipeline" (i.e. one pass). Meshes usually contain a series of materials that define the model. According to the COLLADA spec (again), a material instantiates an effect, fills its parameters with values, & selects a technique. But I see material defined differently in other places, such as just the Lambert, Blinn, Phong "material types/shaded surfaces", or as Metal, Plastic, Wood, etc. In game dev forums, people often talk about implementing a "material/effect system". Is the material not an instance of an effect? Ergo, if I had effect objects, stored in a collection, & each effect instance object with there own parameter setting, then there is no need for the concept of a material... Or am I interpreting it wrong? Please help by contributing your interpretations as I want to be clear on a distinction (if any), & don't want to miss out on the concept of a material if it should be implemented to follow the abstraction of the DirectX FX framework & COLLADA definitions closely.

• Good, simple reasons for having a multiple environments

  - by smp7d

  Throughout my career I had worked at companies that had a collection of different environments for different purposes. We always had more or less our desktop environment, a test environment, a QA environment, a staging environment and a production environment. This went for both servers/applications and any data sources we were using. When I started at my current company I found that 90% of the apps were either developed on a desktop environment against production data sources or developed directly on the production server depending on the platform. I wasn't phased because I was hired in part to make changes to improve the way the development team functioned, which was clear from my interview process. We slowly started to turn the philosophy and pretty soon, most of the apps could be run in either a desktop, test or production environment. Not too long after that staging came around as well. Now most of our developers see the benefit of this methodology and defend it vigilantly. However, we have a number of legacy apps that never got migrated. We also have a number of legacy programmers who think of this as a waste of time. Unfortunately, we got lip service but never full buy-in from management. We got what we thought was a commitment to invest substantially in this about a year ago, but nothing materialized despite the considerable planning that we put into it. Now we are finding that we need more and more environments. We need help from the server/network administration teams for setup and we need participation from the business stakeholders to support the release cycle. We are at a place now where a project can function what I consider "normally" only if you have the right people on the project and the time to set up the proper environments. I'd love to present a complete argument, but management really has no time and interest in hearing me out until there is a critical issue. I cant really articulate the benefits simply as it always just seemed second nature to me. I was wondering if there are any good, simple, irrefutable reasons for the separation of environments that would get managers with no development experience to get behind this idea. Are there any good resources/literature on the topic?

• XNA Moddable Game - Architecture Design and Reflection

  - by David K

  I've decided to embark on an XNA moddable game project of a simple rogue style. For all purposes of this question, I'm going to not be using a scripting engine, but rather allow modders to directly compile assemblies that are loaded by the game at run time. I know about the security problems this may raise. So in order to expose the moddable content, I have gone about creating a generic project in XNA called MyModel. This contains a number of interfaces that all inherit from IPlugin, such as IGameSystem, IRenderingSystem, IHud, IInputSystem etc. Then I've created another project called MyRogueModel. This references MyModel project, and holds interfaces such as IMonster, IPlayer, IDungeonGenerator, IInventorySystem. More rogue specific interfaces, but again, all interfaces in this project inherit from IPlugin. Then finally, I've created another project called MyRogueGame, that references both MyModel and MyRogueModel projects. This project will be the game that you run and play. Here I have put the actual implementation of the Monster, DungeonGenerator, InputSystem and RenderingSystem classes. This project will also scan the mods directory during run time and load any IPlugins it finds using reflection and override anything it finds from the default. For example if it finds a new implementation of the DungeonGenerator it will use that one instead. Now my question is, in order to get this far, I have effectively 2 projects that contain nothing but interfaces... which seems a little... strange ? For people to create mods for the game, I would give them both the MyModel and MyRogueModel assemblies in which they would reference. I'm not sure whether this is the right way to do it, but my reasoning goes as follows : If I write 1 input system, I can use it in any game I write. If I create 3 rogue like games, and a modder writes 1 rendering system, that modder could use the rendering system for all 3 games, because it all comes from the MyModel project. I come from a more web based C# role, so having empty interface projects doesn't seem wrong, its just something I haven't done before. Before I embark on something that might be crazy, I'd just like to know whether this is a foolish idea and whether there's a better (or established) design principle I should be following ?

• CAM v2.0 ships – all new foundation version

  - by drrwebber

  The latest release of the CAM editor toolset is now available on Sourceforge.net – search NIEM. In this all new version the support from Oracle has enabled a transformation of the editor underpinning Java framework and results in 3x performance improvement and 50% better memory utilization. The result of nearly six months of improvements are catalogued in the release notes. http://sourceforge.net/projects/camprocessor/files/CAM%20Editor/Releases/2.0/CAM_Editor_2-0_Release_Notes.pdf/download However here I’d like to talk about the strategic vision and highlight specific new go to features that make a difference for exchange schema designers and with a focus on the NIEM community. So why is this a foundation version? Basically the new drag and drop designer tool allows you to tailor your own dictionary collection of components and then simply select and position those into your resulting exchange structure. This is true global reuse enabled from a canonical domain dictionary collection. So instead of grappling with XSD Schema syntax, or UML model nuances – this is straightforward direct WYSIWYG visual engineering – using familiar sets of business components. Then the toolkit writes the complex XSD Schema for you, along with test samples, documentation, XMI/UML models, Mindmaps and more. So how do you get a set of business components? The toolkit allows you to harvest these from existing schema collections or enterprise data models, or as in the case of NIEM, existing domain dictionary collections. I’ve been using this for the latest IEEE/OASIS/NIST initiative on a Common Data Format (CDF) for elections management systems. So you can download those from OASIS and see how this can transform how you build actual business exchanges – improving the quality, consistency and usability – and dramatically allowing automated generation of artifacts you only dreamed of before – such as a model of your entire major exchange collection components. http://www.oasis-open.org/committees/documents.php?wg_abbrev=election So what we have here is a foundation version – setting the scene and the basis for changing how people can generate and manage information exchanges. A foundation built using the OASIS CAM standard combined with aspects of the NIEM Naming and Design Rules and the UN/CEFACT Core Components specifications and emerging work on OASIS CIQ name and address and ANSI/ISO code list schema. We still have a raft of work to do to integrate this into SOA best practices and extend the dictionary capabilities to assist true community development. Answering questions such as: - How good is my canonical component collection? - How much reuse is really occurring? - What inconsistencies and extensions are there in the dictionary components? Expect us to begin tackling these areas now that the foundation is in place. The immediate need is to develop training and self-start materials – so we will be focusing there for the next couple of months and especially leading up to the IJIS industry event in July in New Jersey, and the NIEM NTE event in August in Philadelphia. http://sourceforge.net/projects/camprocessor

• More on PHP and Oracle 11gR2 Improvements to Client Result Caching

  - by christopher.jones

  Oracle 11.2 brought several improvements to Client Result Caching. CRC is way for the results of queries to be cached in the database client process for reuse.  In an Oracle OpenWorld presentation "Best Practices for Developing Performant Application" my colleague Luxi Chidambaran had a (non-PHP generated) graph for the Niles benchmark that shows a DB CPU reduction up to 600% and response times up to 22% faster when using CRC. Sometimes CRC is called the "Consistent Client Cache" because Oracle automatically invalidates the cache if table data is changed.  This makes it easy to use without needing application logic rewrites. There are a few simple database settings to turn on and tune CRC, so management is also easy. PHP OCI8 as a "client" of the database can use CRC.  The cache is per-process, so plan carefully before caching large data sets.  Tables that are candidates for caching are look-up tables where the network transfer cost dominates. CRC is really easy in 11.2 - I'll get to that in a moment.  It was also pretty easy in Oracle 11.1 but it needed some tiny application changes.  In PHP it was used like: $s = oci_parse($c, "select /*+ result_cache */ * from employees"); oci_execute($s, OCI_NO_AUTO_COMMIT); // Use OCI_DEFAULT in OCI8 <= 1.3 oci_fetch_all($s, $res); I blogged about this in the past.  The query had to include a specific hint that you wanted the results cached, and you needed to turn off auto committing during execution either with the OCI_DEFAULT flag or its new, better-named alias OCI_NO_AUTO_COMMIT.  The no-commit flag rule didn't seem reasonable to me because most people wouldn't be specific about the commit state for a query. Now in Oracle 11.2, DBAs can now nominate tables for caching, either with CREATE TABLE or ALTER TABLE.  That means you don't need the query hint anymore.  As well, the no-commit flag requirement has been lifted.  Your code can now look like: $s = oci_parse($c, "select * from employees"); oci_execute($s); oci_fetch_all($s, $res); Since your code probably already looks like this, your DBA can find the top queries in the database and simply tune the system by turning on CRC in the database and issuing an ALTER TABLE statement for candidate tables.  Voila. Another CRC improvement in Oracle 11.2 is that it works with DRCP connection pooling. There is some fine print about what is and isn't cached, check the Oracle manuals for details.  If you're using 11.1 or non-DRCP "dedicated servers" then make sure you use oci_pconnect() persistent connections.  Also in PHP don't bind strings in the query, although binding as SQLT_INT is OK.

• Unexpected results for projection on to plane

  I want to use this projection matrix: GLfloat shadow[] = { -1,0,0,0, 1,0,-1,1, 0,0,-1,0, 0,0,0,-1 }; It should cast object shadows onto the y = 0 plane from a point light at 1,1,-1. I create a rectangle in the x = 0.5 plane glBegin( GL_QUADS ); glVertex3f( 0.5,0.2,-0.5); glVertex3f( 0.5,0.2,-1.5); glVertex3f( 0.5,0.5,-1.5); glVertex3f( 0.5,0.5,-0.5); glEnd(); Now if I manually multiply these vertices with the matrix, I get. glBegin( GL_QUADS ); glVertex3f( 0.375,0,-0.375); glVertex3f( 0.375,0,-1.625); glVertex3f( 0,0,-2); glVertex3f( 0,0,0); glEnd(); Which produces a reasonable display ( camera at 0,5,0 looking down y axis ) So rather than do the calculation manually, I should be able to use the opengl model transormation. I write this code: glMatrixMode (GL_MODELVIEW); GLfloat shadow[] = { -1,0,0,0, 1,0,-1,1, 0,0,-1,0, 0,0,0,-1 }; glLoadMatrixf( shadow ); glBegin( GL_QUADS ); glVertex3f( 0.5,0.2,-0.5); glVertex3f( 0.5,0.2,-1.5); glVertex3f( 0.5,0.5,-1.5); glVertex3f( 0.5,0.5,-0.5); glEnd(); But this produces a blank screen! What am I doing wrong? Is there some debug mode where I can print out the transformed vertices, so I can see where they are ending up? Note: People have suggested that using glMultMatrixf() might make a difference. It doesn't. Replacing glLoadMatrixf( shadow ); with glLoadIdentity(); glMultMatrixf( shadow ); gives the identical result ( of course! )

• Remote Task Flow vs. WSRP Portlets

The remote task flow is accessed either from a direct browser GET request or, when called from another ADF application, through the task flow call activity. For more information about how to invoke remote task flows from a task flow call activity see chapter 15.6.4 How to Call a Bounded Task Flow Using a URL of the Oracle Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework at http://docs.oracle.com/cd/E23943_01/web.1111/b31974/taskflows_activities.htm#CHDJDJEF Compared to WRSP portlets, remote task flows in Oracle JDeveloper 11g R1 and R2 have a functional limitation in that they cannot be embedded as a region on a page but require the calling ADF application to navigate off to another application and page. The difference between a remote task flow call using the task flow call activity and a simple redirect to a remote Java EE application is that the remote task flow has a state token attached that allows to restore the state of the calling application upon task flow return. A use case for a remote task flow call activity is a "yellow page lookup" scenario in which different ADF applications use an remote task flow to lookup people, products or similar to return a selected value to the calling application. Note that remote task flow calls need to be performed from a bounded or unbounded top level task flow of the calling application. If called from a region (using the parent call activity) in a page, the region state is not recovered upon task flow return. ADF developers recently have identified remote task flows as an architecture pattern to partition their ADF applications into independently deployed Java EE applications. While this sounds like a desirable use of the remote task flow feature, it is not possible to achieve for as long as remote task flows don't render as an ADF region.

• RIM's current BB7 developer toolset is a joke

  - by mbrit

  tl;dr - RIM's current developer toolset is not fit for purpose.Background to this is that I'm currently working on a PhoneGap/Cordova project for a client that has to run on BlackBerry. The tooling is so ridiculous to use that even though I had a gentle dig at them in a Guardian piece it's worth having a more full-on attack.At the moment, RIM's pitch is that apps are built for the current BBOS7 devices using WebWorks. This is an HTML-based toolset. Essentially a browser is spun up in a native app container and your app is powered by JavaScript. Specific JavaScript libraries exist that thunk down to native capabilities no the device. I happen to use PhoneCap/Cordova in combination with this.The tooling is non-existent. I'm using TextMate, Ant, and Terminal to develop the app. There's no "console.log" output, and no debugging. The only way to instrument the app is to put "alert" calls in your code.Apart from the fact that that's *not* fine in 2012, how about this… every time you deploy a new app to the device, the device has to reboot. This process takes six minutes on a relatively modern BlackBerry device. How about this as well - in order to get a file into the package it has to be signed. My small app over here has 100 different files (75 or so generated). Signing doesn't happen locally, it happens on RIM's servers in Waterloo. Thus whenever you deploy the app you have this utility have to call RIM's servers 100 times. More to the point, sometimes during the day these servers have "micro-downtime" moments where they're unreachable for five or ten minutes, normally two or three times a day. Oh yes, you'll also get an email sent to you per signing on success or failure. 100 inbound emails, per deployment.(I started this post at the beginning of one of these cycles, by the way. That's how long it takes to build and deploy *once*. By the way, the change I made didn't work.)To clarify:* Change the script,* Build it using Ant,* Ant will spin up a Java app that talks to RIM's servers to sign it.* Receive 100 emails, assuming the server is up.* App deployed - takes about 30 seconds.* BlackBerry device restarts - takes about six minutes.* Find and open the app. Go through security prompts.* Test the app, with no "console.log" output and no debugger."Why not use the simulator?" I hear you ask. Well, apart from the fact that the simulator refused to reach any network service over HTTPS that I happen to own? (Some people suggest changing DNS settings for this known issue.) Admittedly, the simulator does show you console.log, but you still have the "six minute" restart issue on the simulator.Developers will understand this problem. Breaking concentration for six-plus minutes every time you want to deploy an app turns developing into a nightmare. Combining that with no worthy debugging tools turns the toolset into a joke.

• Media server...serving files...............for a limited time only

  - by Craig

  I’m new to Ubuntu and am seeking help with a media server I have built. I have a couple of HTPCs in my house running XBMC. I wanted to build one for the family room working double duty as a HTPC, and media server to share movies, TV shows, music, etc. on my Windows network. So using some spare old parts I had lying around I decided to go CRAZY and build my first Linux box. I used Ubuntu because it seemed to be the most user friendly variant, especially for people that are new to Linux. I had to do a few things to get the media files shared properly on my network: Made sure my two media drives auto-mount every time I boot the computer by editing the “fstab” file – “sudo nano /etc/fstab” Installed Samba - “sudo apt-get install samba” Set a password for Samba - “sudo smbpasswd –a USERNAME” Edited the Samba configuration file to make sure the computer was in my networks workgroup – “sudo nano /etc/samba/smb.conf” In the file manager (not sure if that’s the right name for it), I right-clicked my media folders and set the sharing and permissions. The sharing was done without guest access, and permissions were set to; Owner, Group, and Others - Access: Create and Delete Files. Adjusted the Power Management settings to never put the system into sleep mode. I checked to see if I had access to the files from a Windows 7 machine and I did (Woo Hoo!). But when I tried to play any of my video files from the Windows machine (using VLC media player), they would only play for about 2-5 minutes and then they would stop with an error message saying that the file could not be accessed (Booo...). I tried playing some files through XBMC running in Windows and they worked for a bit longer (about 10-15mins), but they also stopped playing. I installed the Linux version of XBMC on the server and played the files locally with no problems. It doesn’t seem to be an issue with the files themselves, it seems to be a sharing problem on my network. So my question to the Ubuntu gurus out there is: Did I miss adding/editing something in the Samba configuration file? Did I use the right method to share my media files (file manager vs. using the terminal)? Is it possible for the computer to still go to sleep without the screen going black (does that even make sense?). Are there any special settings in Ubuntu that I should be using since this computer as a media server (is there a media server mode?...!...?). Any help on this matter would be greatly appreciated. Thanks

• An Epic Question "How to call a method when the page loads"

  - by Arunkumar Ramamoorthy

  Quite often, there comes a question in OTN, with different subjects, all meaning "How to call a method when my ADF page loads?". More often, people tend to take the approach of ADF Phase Listener by overriding before/afterPhase methods.In this blog, we will go through different options in achieving it.1. Method Call Activity as default activity in Taskflow :If the application is built with taskflows, then this is the best suited approach to take. 1.a. Calling a Data Control Method :To call a Data Control method (ex: A method in AMImpl exposed as client interface), simply Drag and Drop the method as Default Method Call Activity, then draw a control flow case from the method to your page. Once after this, drop the taskflow as region in main page. When we run the main page, the Method Call Activity would be called first, and then the page will be rendered.1.b. Calling a Method in Backing Bean: To call a method in the backing bean before pageload, we can follow the similar approach as above. Instead of binding the Method Call Activity to an action/method binding in pagedef, we bind to the method. Insert a Method Call Activity (and make it as default) from the Component Palette. Double click on to select a method to bind. This approach can also be used, to perform some action in backing bean along with calling a method Data Control (just need to add bindings code in backing bean to execute DC method). 2. Using invokeAction Executable :If the application is built with pages and no taskflows are involved, then this option can be taken into consideration.In the page definition of the page, add an invokeAction Executable and bind it to the method needed to be executed. 3. Using combination of Server and Client Listeners : If the page does not have any page definition, then to call a method in backing bean, this approach can be taken. In this, a serverListener would be added at the document level, which would be calling the method in backing bean. Along with this, a clientListener would be added with "load" type (i.e will be triggered when the page loads), which would queue a serverEvent to trigger the method. 4. Using Page Phase Listener :This should be the last resort. Care should be taken when using this approach since the Phase Listener would be called for each request sent by the client.Zeeshan Baig's blog covers this scenario.

• Please Stop Voting Against a Candidate

  - by Brian Lanham

  DISCLAIMER:  This is not a post about “Romney” or “Obama”.  This is not a post for whom I am voting.  This is simply a post to address an issue that I cannot ignore any longer.  This two-party system that we have allowed to establish a foothold is killing this country.    More than 2 Options I was recently asked, “If you had to choose Romney or Obama who would you pick?”  I replied “Non sequiter.  The founders of this nation ensured that I never have to pick from only two candidates.”  But somehow that is the way this country’s citizens think.  I told someone last week that there are around 20 candidates for president and she was genuinely surprised.  (There are actually 25 candidates.)  She had no idea there were that many and, even though she knew there are more, she didn’t know any names beyond Romney and Obama.  Well, I am going to try and educate people like her on other options. Vote for a Candidate, not against another Candidate So this post is the first in a series with a little bit of information about each candidate for president.  I implore you…I beg you, please do your civic duty and conduct a little bit of investigation and research on your own to find the right candidate for you.  Hey, if your candidate is Romney or Obama, that’s fine.  As long as it’s an educated decision.  But please…stop voting against a candidate.  Start voting for a candidate. A List of CandidatesAs I mentioned, I am going to write a little something about each candidate and I’m going to go by alphabetical order by PARTY, then by CANDIDATE LAST NAME so as to not show any bias. P.S. – If you want to know the candidate I selected I am happy to tell you.  But that’s not what this series is about.PARTYCANDIDATEAmerica's Party   Tom HoeflingAmerican Third Position PartyMerlin MillerAmericans Elect PartyNo candidates met the requirement to enter into the online caucus.Constitution PartyVirgil GoodeDemocratic Party   Barack ObamaGrassroots Party   Jim CarlsonGreen Party   Jill SteinIndependent American Party   Will ChristensenJustice PartyRocky AndersonLibertarian Party   Gary JohnsonObjectivist PartyTom StevensPeace and Freedom Party   Roseanne BarrReform PartyAndre BarnettRepublican PartyMitt RomneySocialism and Liberation PartyPeta LindsaySocialist Equality PartyJerry WhiteSocialist Party USAStewart AlexanderSocialist Workers PartyJames HarrisIndependent Candidates Jeff BossRichard DuncanJerry Litzel Dean Morstad Jill Reed Randall TerrySheila Tittle Michael Vargo

• Recovering an Ubuntu installation - Ubuntu eats itself after 'sudo apt-get install -f'

  - by Tony Martin

  Updater (I assume) put a no entry style alert icon on the panel which informed me that certain package dependencies were not up to snuff. Upgrades were thereafter only partial. The dialogue advised that I sudo apt-get install -f. I did this hoping that app-get would fulfil dependencies and replace corrupted files and watched it systematically remove every component of linux, both the stuff I had installed and the core ubuntu packages. I could only assume at this stage that this was in preparation for a fresh install but, of course, I know better now - if you find yourself with apt-get warning you that you are about to remove several hundred packages and asking you to type an involved confirmation string seek advice before proceeding. I digress. This was a 64 bit install of 12.04. All that is left is grub pointing to a couple of windows recovery partitions on the hard drive. Thankfully the Ext4 partition is reachable from a stick boot. EDIT: I've logged onto the machine with a 64 bit stick and can see the file structure left behind by apt-get after {ahem} fixing. My first instinct was to run install from the stick but it seemed to want to do another install rather than a repair. My question then: is there a way to recover the current installation so that if I reinstall the packages I had they will pick up the original settings? I'm particularly worried about losing email from evolution - the rest I could probably lash back together. As for the use of PPA I'm not sure what you're driving at. I generally use Ubuntu Software Centre to install software, though I have used terminal scripts to add new repositories and software successfully following guidance on various websites. The most recent change I made was a downgrade of Wine in an attempt to install and run excel2007 (a necessity, I think, as I have VBA work to do). The installer had stalled and had to be killed. I wonder if that corrupted whatever database holds a model of the package installation structure. I would also be interested to know how this disaster came about. I see people in the know recommending the sudo apt-get install -f as a fairly innocuous cure in similar circumstances. Thanks for your attention, Tony Martin p.s. Do please forgive the rant aspects of the original post. It's hard to write rationally with a large hole in the pit of your stomach.

• Commerce, Anyway You Want It

  - by David Dorf

  I believe our industry is finally starting to realize the importance of letting consumers determine how, when, and where to interact with retailers.  Over the last few months I've seen several articles discussing the importance of removing the barriers between existing channels. Paula Rosenblum of RSR first brought the term omni-channel to my attention back in September. She stated, "omni-channel retail isn’t the merging of channels – rather, it’s the use of all possible channels (present and future) to enhance the customer experience in a profitable way." I added to her thoughts in this blog posting in which I said, "For retailers to provide an omni-channel experience, there needs to be one logical representation of products, prices, promotions, and customers across all channels. The only thing that varies is the presentation of the content based on the delivery mechanism (e.g. shelf labels, mobile phone, web site, print, etc.) and often these mechanisms can be combined in various ways." More recently Brian Walker of Gartner suggested we stop using the term multi-channel and begin thinking more about consumer touch-points. "It is time for organizations to leave their channel-oriented ways behind, and enter the era of agile commerce--optimizing their people, processes and technology to serve today's empowered, ever-connected customers across this rapidly evolving set of customer touch points." Now Jason Goldberg, better known as RetailGeek, says we should start breaking down the channel silos by re-casting the VP of E-Commerce as the VP of Digital Marketing, and change his/her focus to driving sales across all channels using digital media. This logic is based on the fact that consumers switch between channels, or touch-points as Brian prefers, as part of their larger buying process. Today's smart consumer leverages the Web, mobile, and stores to provide the best shopping experience, so retailers need to make this easier. Regardless of what we call it, the key take-away is that "multi-channel" is not only an antiquated term but also an idea who's time has passed.  Today, retailers must look at e-commerce, m-commerce, f-commerce, catalogs, and traditional store sales collectively and through the consumers' eyes.  The goal is not to drive sales through each channel but rather to just drive sales -- using whatever method the customer prefers.  There really should be just one cart.

• Upstart: How does rc job work / order of (contradicting) "start on ..." and "stop on ..." stanzas

  - by Binarus

  Hi, I just can't understand how Upstart's rc job definition in Natty 11.04 works. To illustrate the problem, here is the definition (empty lines and comments are left out): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL Let's suppose we currently are in runlevel 2 and the rc job is stopped (that is exactly the situation after booting my box and logging in via SSH). Now, let's assume that the system switches to runlevel 3, for example due to a command like "telinit 3" given by root. What will happen to the rc job? Obviously, the rc job will be started since it is currently stopped and the event runlevel 3 is matching the start events. But from now on, things are unclear to me: According to the manual $RUNLEVEL evaluates to the new runlevel when the job is started (that means 3 in our example). Therefore, the next stanza "stop on runlevel [!$RUNLEVEL]" translates to "stop on runlevel [!3]"; that means we have a first stanza which will trigger the job, but the second stanza will never stop the job and seems to be useless. Since I know that the Ubuntu / Upstart people won't do useless things, I must be heavily misunderstanding something. I would be grateful for any explanation. While trying to understand this, an additional question came to my mind. If I had contradicting start and stop triggers, for example start on foo stop on foo what would happen? I swear I never will do that, but I am nevertheless very interested in how Upstart handles that on the theoretical level. Thank you very much! Editing the question as a reaction on geekosaur's first answer: I can see the parallelism, but it is not that easy (at least, not to me). Let's assume the job aurrently is still running, and a new runlevel event comes in (of course, the new runlevel is different from the current one). Then, the following should happen: 1) The job is single instance. That means that "start on ..." won't be triggered since the job is currently running; $RUNLEVEL is not touched. 2) "stop on ..." will be triggered since the new runlevel is different from $RUNLEVEL, so the job will be aborted. 3) Now, the job is stopped and waiting. I can't see how it is restarted with the new runlevel. AFAIK, initctl emits events only once, so "start on ..." won't be triggered and the new runlevel won't be entered. I know that I still misunderstanding something, and I am grateful for explanations. Thank you very much!

• Software monetization that is not evil

  - by t0x1n

  I have a free open-source project with around 800K downloads to date. I've been contacted by some monetization companies from time to time and turned them down, since I didn't want toolbar malware associated with my software. I was wondering however, is there a non-evil way to monetize software ? Here are the options as I know them: Add a donation button. I don't feel comfortable with that as I really don't need "donations" - I'm paid quite well. Donating users may feel entitled to support etc. (see the second to last bullet) Add ads inside your application. In the web that may be acceptable, but in a desktop program it looks incredibly lame. Charge a small amount for each download. This model works well in the mobile world, but I suspect no one will go for it on the desktop. It doesn't mix well with open source, though I suppose I could charge only for the binaries (most users won't go to the hassle of compiling the sources). People may expect support etc. after having explicitly paid (see next bullet). Make money off a service / community / support associated with the program. This is one route I definitely don't want to take, I don't want any sort of hassle beyond coding. I assure you, the program is top notch (albeit simple) and I'm not aware of any bugs as of yet (there are support forums and blog comments where users may report them). It is also very simple, documented, and discoverable so I do think I have a case for supplying it "as is". Add affiliate suggestions to your installer. If you use a monetization company, you lose control over what they propose. Unless you can establish some sort of strong trust with the company to supply quality suggestions (I sincerely doubt it), I can't have that. Choosing your own affiliate (e.g. directly suggesting Google Toolbar) is possibly the only viable solution to my mind. Problem is, where do I find a solid affiliate that could actually give value to the user rather than infect his computer with crapware? I thought maybe Babylon (not the toolbar of course, I hate toolbars)?
