• View Images and Videos in 3D in Firefox

  - by Asian Angel

  Different websites have their own format for viewing images and videos, but may not be a lot of fun to use. The Cooliris extension for Firefox lets you view those same images and videos in a dynamic 3D format. Before For our example we conducted a search for nature photos at Flickr. You could view them in a static format or even as a slideshow but what about something more dynamic looking? After As soon as the extension has finished installing, you will notice a new toolbar button used for launching the Cooliris tab. When you launch the Cooliris tab you will have an expandable menu system in the upper left corner. A speed dial setup in the center. And a small toolbar in the lower right corner Before going further you should check and make any desired adjustments in the preferences to enhance your viewing experience. In the upper right corner you can start your search by selecting from the available sources. The same search for nature images is more focused and clean looking this time. Clicking on an image will bring it forward and enlarge it. You can use the slider tool at the bottom of the tab to browser left or right through the images and videos. And when you find one that interests you, click on the popout button to open it in a new tab. Conclusion The Cooliris extension makes viewing images and videos fun and interactive with its’ 3D style format.

• Open World Day 3

  - by Antony Reynolds

  A Day in the Life of an Oracle OpenWorld Attendee Part IV My third day was exhibition day for me!  I took the opportunity to wander around the JavaOne and OpenWorld exhibitions to see what might be useful for me when selling WebLogic, Coherence & SOA Suite.  I found a number of interesting vendors and thought I would share what I found here.  These are not necessarily endorsements, but observations on companies that I thought had interesting looking products that fill a need I have seen at customers. Highly Available EBS Upgrades A few years ago I worked with a customer that was a port authority.  They wanted to tie E-Business Suite into their operations to provide faster processing of cargo and passengers.  However they only had a 2 hour downtime window to perform upgrades.  This was not a problem for core database and middleware technology, this could accommodate those upgrade timescales easily.  It was a problem for EBS however so I intrigued to find Rapid E-Suite Inc offering an 11i to 12i upgrade service that claims to require no outage.  This could be a real boon to EBS customers like my port friends that need to upgrade without disruption to their business. Mobile on WebLogic I have come across a number of customers who want a comprehensive mobile solution, connected and disconnected operation and so forth.  ADF only addresses part of these requirements currently so I was excited to discover mFrontiers Inc offering an apparently comprehensive solution that should integrate easily with Oracle SOA Suite to mobile enable a SOA infrastructure.  The ability to operate without a network is important for many applications, particularly in industries that require their engineers to enter buildings to perform maintenance or repairs, because network access is not always available – many of my colleagues don’t have mobile access from their homes because they live in the middle of nowhere – and disconnected support is crucial in these situations. Sharepoint Connector for WebCenter Content Obviously Sharepoint is an evil pernicious intrusion into a companies IT estate but it is widely deployed and many people like it but also would like to take advantage of Oracle products such as WebCenter Content.  So I was encouraged to see that Fishbowl Solutions have created a connector for Sharepoint that allows it to bring in content from WebCenter, it looks like a valuable way to maintain the Sharepoint interface end users are used to but extend the range of content by pulling stuff (technical term for content) from WebCenter.   Load Balancing The Enterprise Deployment Guides are Oracles bible on building highly available FMW environments, and each of them requires a front end load balancer.  I have been asked to help configure F5 Load Balancers on a number of occasions over my time at Oracle and each time I come back to it I find more useful features have been added to the BigIP line of load balancers that F5 sell, many of their documents are tailored to FMW.  I like F5, they provide (relatively) easy to use products that do what they say on the side of the box.  They may not have all the bells and whistles of some of their more expensive competitors but they do the job and do it well!  Besides which I like their logo! Other Stuff I saw lots of other interesting products and services, such as a lightweight monitoring tool for Coherence, Forms migration services, JCAPS migration services and lots of cool freebies to take home to the children! A Quiet Night Wednesday night was the partner appreciation event and I had decided to go back to the hotel and have an early night.  I decided to attend the last session of the day – a Maven/Hudson/WebLogic tutorial.  I got the wrong hotel for the session and snuck in 20 minutes late at the back and starting working on the hands on workshop.  One of my co-attendees raised his hand for help and as the presenter came over to help he suddenly stopped and yelled – “Is that Antony”!  It was my old friend Steve Button who used to be based in Redwood Shores but is now a WebLogic guru PM in Australia.  It was good to catch up with him.  As he yelled out a guy with really bad posture turned around to see who he was talking to, this turned out to be my friend Simon Haslan, Oracle ACE from the UK.  After the tutorial Simon and I retired to the coffee shop to catch up and share stories.  2 and half hours later we decided it was time to retire, so much for an early night but great to renew old friendships and find out what real customers are worrying about.

• It's intellisense for SQL Server

  - by Nick Harrison

  It's intellisense for SQL Server Anyone who has ever worked with me, heard me speak, or read any of writings knows that I am a HUGE fan of Reflector.    By extension,  I am a big fan of Red - Gate   I have recently begun exploring some of their other offerings and came across this jewel. SQL Prompt is a plug in for Visual Studio and SQL Server Management Studio.    It provides several tools to make dealing with SQL a little easier for your friendly neighborhood developer. When you a query window in a database, the plugin kicks in and gathers the metadata for the database that you are in.    As you type a query, you get handy feedback like a list of tables after you type select.    You can select one of the tables, specify * and then tab to expand the select clause to include all of the columns from the selected table.    As you are building up the where clause, you are prompted by the names of columns in the selected tables. If you spend any time writing ad hoc queries or building stored procedures by hand, this can save you substantial time. If you are learning a new data model, this can greatly cut down on your frustration level. The other really cool thing here is Format SQL.   I have searched all over the place for a really good SQL formatter.    Badly formatted  SQL is so much harder to read than well formatted SQL.   Unfortunately, management studio offers no support for keeping your SQL well formatted.    There are many tools available to format your SQL.   Some work better than others.    Some don't work that well at all.   Most will give you some measure of control over how the formatted SQL looks.    SQL Prompt produces good results and is easy to configure. Sadly no tool is perfect, and what would we be without a wish list.    There are some features that I would like to see: Make it easier to paste SQL in and out of code.    Strip off string builder, etc Automate replacing hard coded values with bind variables or parameters In addition to reformatting SQL, which is a huge refactor, support for other SQL refactors would be nice.    Convert join to sub query and vice versa come to mind Wish list a side, this is a wonderful tool that easily saves me an hour or more on most weeks.

• Why is there nobody talking about an alternative to HTML & CSS? [closed]

  - by Nic

  HTML is such an old and cumbersome language, which was intended just to markup text. Today it's very rare to see a static HTML website, or a site with only text or a very simple layout. As a web developer I find it inconvenient to use HTML & CSS, very repetitive and cumbersome. I think that for a lot of website it could be simplified a lot. Tim Berners-Lee (W3) wrote a document named "The World Wide Web: Past, Present and Future" in August 1996 ... though HTML will be considered part of the established infrastructure (rather than an exciting new toy), there will always be new formats coming along, and it may be that a more powerful and perhaps a more consistent set of formats will eventually displace HTML. So, more than 15 years later, HTML is still here and it's here to stay. Why? Why searching for xml alternatives brings so much relevant result, but searching for html alternatives brings almost none relevant results? Answers like "it's too hard to change a standard" aren't answering the question since a lot of new standards emerged since the initiation of the web. I'm also not searching for answers that suggest using tools to simplify the process or formats that anyhow depends on HTML or CSS, technologies that currently require a plugin and not even trying to become an open standards (like Flash) aren't an answer neither. BTW, here are 2 articles written more than two years ago as food for thought, it might help with writing a better answers. "HTML, CSS, and Web Development Practices: Past, Present, and Future" describing a very related problem, by Jens O. Meiert. "A Brief History of HTML" by Scott Reynen, Here is a quote from the end: So now you can answer questions about HTML5 without even looking at the draft, which is handy, because the draft is 400+ pages long. Why is there a new tag in HTML5? Because some browser vendor (maybe the one that also owns a large video site) wanted it. Why are there so many scriptable interface elements in HTML5? Because some browser vendor (maybe the one selling phones without Flash support) wants them. Why is there no support for RDFa in HTML5? Apparently no browser vendor wanted it. Is that the future?

• Somewhere to get inspiration - Pair up the creative with the tech

  - by Morten Bergfall

  I am a somewhat green developer; some work experience, last year of school. As most of you, I am constantly working on an assortment of personal projects. Since my mind often has a somewhat drifting characteristic; I am not always able to keep the projects in check. After some time they all exhibit the moral fiber of Vikings, harlots and chain-letter-knitters. This includes constant forking, round-abouting, eating of school assignments of rather mundane, and hence pretty yawn-inducing, specifications, and of course quite a bit of gathering of folder dust. Well, on to my question....is there a place, forum... or something with the purpose of linking people with ideas to the people actually being able to bring said ideas to life? Of course, I know of the professional ones, like rent-a-coder and such. And there seem to be a lot of open source projects available for participation. What I'm looking for doesn't really fit into any of those categories....the form would be somewhat like rent-a-coder, but this is ideas&inspiration, not bubble-sort-my-quarterly-for-a-buck. The possibilities for developing bonds, spicy code, and plain old fun seem quite possible.As I see it, the main benefit would be that we (that is the tech-flipside of the proverbial eCoin) get something worthwhile to do, rather than squeeze the last creative grain out of our code-heavy brains.To give it some perspective...: My last project consists of an absurd jQuery-plugin that includes animated png-robots migrating from Google Earth to drag a html-element of your choosing onto the map, where it gets color, for so to be dragged back by this poorly animated robot.... Often, the line between the creative and the tech is blurred, to say the least. I wouldn't think that would be a problem. Think someone who has developed a nifty little windows application, then sees possibility for a broader use, perhaps some sort of networking functionality. This fellow sadly lacks the skill to implememet this. So he, she or it would then seek a developer with the know-how and they could complete this project together. So, do any of you know of such a place, or can nudge in the right direction? And yes, I understand completely that I should be dedicating myself to doing school work, or applying for mundane developer positions, so please.... :-) UPDATE Sadly, I'm situated in Oslo, Norway, and the number of developers are somewhat limited...and I have had quite some ahem personality issues with the ones who are available ;-) So I feel I must go deeper; search the multitude of the web...

• Easy Profiling Point Insertion

  - by Geertjan

  One really excellent feature of NetBeans IDE is its Profiler. What's especially cool is that you can analyze code fragments, that is, you can right-click in a Java file and then choose Profiling | Insert Profiling Point. When you do that, you're able to analyze code fragments, i.e., from one statement to another statement, e.g., how long a particular piece of code takes to execute: https://netbeans.org/kb/docs/java/profiler-profilingpoints.html However, right-clicking a Java file and then going all the way down a longish list of menu items, to find "Profiling", and then "Insert Profiling Point" is a lot less easy than right-clicking in the sidebar (known as the glyphgutter) and then setting a profiling point in exactly the same way as a breakpoint: That's much easier and more intuitive and makes it far more likely that I'll use the Profiler at all. Once profiling points have been set then, as always, another menu item is added for managing the profiling point: To achieve this, I added the following to the "layer.xml" file: <folder name="Editors"> <folder name="AnnotationTypes"> <file name="profiler.xml" url="profiler.xml"/> <folder name="ProfilerActions"> <file name="org-netbeans-modules-profiler-ppoints-ui-InsertProfilingPointAction.shadow"> <attr name="originalFile" stringvalue="Actions/Profile/org-netbeans-modules-profiler-ppoints-ui-InsertProfilingPointAction.instance"/> <attr name="position" intvalue="300"/> </file> </folder> </folder> </folder> Notice that a "profiler.xml" file is referred to in the above, in the same location as where the "layer.xml" file is found. Here is the content: <!DOCTYPE type PUBLIC '-//NetBeans//DTD annotation type 1.1//EN' 'http://www.netbeans.org/dtds/annotation-type-1_1.dtd'> <type name='editor-profiler' description_key='HINT_PROFILER' localizing_bundle='org.netbeans.eppi.Bundle' visible='true' type='line' actions='ProfilerActions' severity='ok' browseable='false'/> Only disadvantage is that this registers the profiling point insertion in the glyphgutter for all file types. But that's true for the debugger too, i.e., there's no MIME type specific glyphgutter, instead, it is shared by all MIME types. Little bit confusing that the profiler point insertion can now, in theory, be set for all MIME types, but that's also true for the debugger, even though it doesn't apply to all MIME types. That probably explains why the profiling point insertion can only be done, officially, from the right-click popup menu of Java files, i.e., the developers wanted to avoid confusion and make it available to Java files only. However, I think that, since I'm already aware that I can't set the Java debugger in an HTML file, I'm also aware that the Java profiler can't be set that way as well. If you find this useful too, you can download and install the NBM from here: http://plugins.netbeans.org/plugin/55002

• Javascript Implementation Patterns for Server-side MVC Websites

  - by tmo256

  I'm looking for information on common patterns for initializing and executing Javascript page by page in a "traditional" server-side MVC website architecture. A few months ago, my development team began, but abandoned, a major re-architecture of our company's primary web app, including a full front-end redesign. In the process, there was some debate about the architecture of the Javascript in the current version of the site, and whether it fit into a clear, modern design pattern. Now I've returned to the process of overhauling the front end of this and several other MVC websites (Ruby on Rails and MVC.net) to implement a responsive framework (Bootstrap), and in the process will again need to review then revamp and update a lot of Javascript. These web applications are NOT single-page Javascript applications (in fact, we are ripping out a lot of Ajax) or designed to require a Javascript MVC pattern; these apps are basically brochure, catalog and administrative sites that follow a server-side MVC pattern. The vast majority of the Javascript required is behavioral, pre-built plugins (JQuery and Bootstrap, et al) that execute on specific DOM nodes. I'm going to give a very brief (as brief as I can be) run-down of the current architecture only in order to illustrate the scope and type of paradigm I'm talking about. Hopefully, it will help you understand the nature of the patterns I'm looking for, but I'm not looking for commentary on the specifics of this code. What I've done in the past is relatively straight-forward and easy to maintain, but, as mentioned above, some of the other developers don't like the current architecture. Currently, on document ready, I execute whatever global Javascript needs to occur on every page, and then call a page-specific init function to initialize node-specific functionality, retrieving the init method from a JS object. On each page load, something like this will happen: $(document).ready(function(){ $('header').menuAction(); App.pages.executePage('home','show'); //dynamic from framework request object }); And the main App javascript is like App = { usefulGlobalVar: 0, pages: { executePage: function(action, controller) { // if exists, App.pages[action][controller].init() }, home: { show: { init: function() { $('#tabs').tabs(); //et. al }, normalizeName: function() { // dom-specific utility function that // doesn't require a full-blown component/class/module } }, edit: ... }, user_profile: ... } } Any common features and functionality requiring modularization or compotentizing is done as needed with prototyping. For common implementation of plugins, I often extend JQuery, so I can easily initialize a plugin with the same options throughout the site. For example, $('[data-tabs]').myTabs() with this code in a utility javascript file: (function($) { $.fn.myTabs = function() { this.tabs( { //...common options }); }; }) Pointers to articles, books or other discussions would be most welcome. Again, I am looking for a site-wide implementation pattern, NOT a JS MVC framework or general how-tos on creating JS classes or components. Thanks for your help!

• Split Internet Explorer into Dual-Panes

  - by Asian Angel

  If you have a wide screen monitor then you may want to make better use of Internet Explorer’s browser window area. Now you can split the browser window into dual-panes as needed with the IE Split browser plugin. Note: Requires .NET Framework 2.0 or higher (link provided below). IE Split in Action If you are using an older version of this software here is something to keep in mind before upgrading to the 2.0 release. Once you have installed IE Split you will notice a new toolbar added to your browser. As seen here, you can condense it down tightly and access it using the drop-down bar. A closer look at the drop-down bar. Notice the address bar…this will be for the left pane when you split the browser window. Here is our browser split into dual-panes. There are two address bars and two tab/title bars each corresponding to their appropriate pane. It may look slightly backwards at first but is not hard to get used to. A better view of the left pane with the IE Split navigation & title bars showing. Note: The title bar can be hidden if desired. And the right pane. You can also have multiple “split” tabs open if needed. There is nothing quite like getting double the value for the same amount of space. When you no longer need dual-panes open just click on the “x” to close IE Split down. All back to normal again. Conclusion While might not be for everyone this can still be useful for those who need side-by-side access to websites without using multiple separate windows.

• Ubuntu on Pandaboard giving me troubles

  - by Jeroen Jacobs

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

• Walmart and Fusion Apps

  - by ultan o'broin

  Photograph: Misha Vaughan I attended Fusion Apps (yes, I know I am supposed to say "Oracle Fusion Applications", but stuffy old style guides are a turn-off in interwebs conversations) User Experience Advocate (FXA) training in Long Beach, California last week; a suitable location as ODTUG KSCOPE 11 was kicking off and key players were in the area. As a member of Oracle's Apps-UX team I know the Fusion Apps messaging, natch, and done some other Fusion Apps go-to-market content work too. For the messaging details themselves, see Lonneke Dikmans (@lonnekedikmans) great blog, by the way. However, I wanted some 'formal' training combined with the opportunity to meet and learn from people already out there delivering those messages. The idea in me reaching out to Misha Vaughan, Apps-UX FXA maven, to get me onto this training was that in addition to my UX knowledge, I could leverage my location in EMEA and hit up customer events more quickly and easily. Those local user groups do like to hear the voice of locals too you know (so I need to work on that mid-Atlantic accent). I'm looking forward to such opportunities. The training was all smashing stuff, just the right level of detail, delivered professionally and with great style and humor. I was especially honored to be paired off for my er, coaching with Debra Lilley (@debralilley), who shared with everyone all kinds of tips and insights from her experiences of delivering the message and demo. For me, that was the real power of the FXA event--the communal, conversational aspect--the meeting up with people who had done all this for real, the sharing in their experiences, while learning along with other newbies. Sorry, but that all-important social aspect doesn't work so well with remote meetings. Katie Candland (Apps-UX) gave us a great tour of the Fusion Apps demo and included some useful presentational tips too (any excuse to buy that iPad). It's clear to me that the Fusion Apps messaging and demos really come alive with real-world examples that local application users will recognize, and I picked up some "yes, that's my job made easier" scene-stealers from Debra and Karen Brownfield too, to add to the great ones already provided. This power of examples shouldn't surprise anyone, they've long been a mainstay of applications user assistance, popular with users. We'll offer customers different types of example topics in the Fusion Apps online help too (stay tuned), and we know from research how important those 3S's (stories, scenarios, and simulations) are to users when they consume and apply information. Well, we've got the simulation, now it's time for more stories and scenarios. If you get a chance to participate in an FXA event (whether you are an Oracle employee or otherwise), I'd encourage it. It's committing your time and energy for sure, but I got real bang for the buck from it for my everyday job too. Listening to the room's feedback on the application demo really brought our internal design work to life, and I picked up on some things that I need to follow up on (like how you alphabetically sort stuff in other languages). User experience is after all, about users. What will I be doing next, and what would I like to see happen? Obviously, I need to develop my story-telling links with the people I met in Long Beach and do some practicing with the materials, and then get out there and deliver them at a suitable location. The demo is what it is right now, and that's a super-rich demo that I know everyone will want to see and ask questions about. Then, as mentioned by attendees at the FXA event, follow up on those translated and localized messages for EMEA (and APAC), that deal with different statutory or reporting requirements of the target markets. Given my background I would say that, wouldn't I? However, language is part of the UX, and international revenue is greater than US-only revenue for Oracle, so yes dear, we all need to get over the fact that enterprise apps users don't all speak, or want to speak, American-English. Most importantly perhaps, the continued development of a strong messaging community between Oracle and partners and customers where we can swap and share those FXA messaging stories and scenarios about Fusion Apps in a conversational way. The more the better, a combination of online and face-to-face meetings. I must also mention the great dinner after the event at Parker's Lighthouse, and the fun myself and Andrew Gilmour (Apps-UX) had at our end of the table talking about just about everything except Fusion Apps with Ronald Van Luttikhuizen and Ben Prusinski (who now understands the difference between Cork and Dublin people. I hope). Thanks to all the Apps-UXers who helped bring the FXA training to town, and to Debra and all the others that I am too jetlagged to mention right who were instrumental in making it happen for me. Here's to the next one. And the Walmart angle? That was me doing my Robert Scoble (ScO'bilizer?)-style guerilla smart phone research in Walmart in Long Beach, before the FXA event. It's all about stories for me. You can read more about it on the appslab blog (see the comments).

• Ubuntu won't suspend automatically any more

  - by Sparhawk

  In the last month or so, Ubuntu (12.04) has stopped sleeping automatically. I've gone to System Settings Power, and verified (and toggled) "suspend on inactive for" to 5 minutes (for both battery and "when plugged in"), but the system stays awake. I've also tried used code similar to $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 300 $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 300 to set the timeout values. I've also verified these in dconf Editor. Previously, I could set this quite low to make my computer sleep quickly, but now it no longer works either. I'm not sure if this is relevant, but under old versions of Ubuntu, if I wanted my computer to never suspend (via the CLI), I would also have to set $ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac false At some point, this seemed to have been depreciated (and also gave me the error "No such key 'sleep-inactive-ac'"). I found that it it was enough to set sleep-inactive-ac-timeout to 0. This worked for a while, but at some point auto-suspend stopped working as stated above. Oddly enough, the sleep-inactive-ac key is still present when I look via dconf editor. However, when I click it, it says "no schema", and the summary, etc. fields are blank. To test if the dconf power plugin was working, I tried playing around with other settings in the schema. Idle-dim-time and idle-dim-ac work as expected . However, setting sleep-display-ac to 5 seconds has no effect. I'm also not sure if this is relevant, but I've uninstalled gnome-screensaver, and installed xscreensaver. I have tried killing xscreensaver and re-installing gnome-screensaver, but this did not help. I've also had some trouble with DPMS. I'm not sure if this is related, but I'll put the information here, just in case. Using xscreensaver, I set Power Management to enabled, with standby and suspend timeouts to 10 minutes. I've verified these settings in ~/.xscreensaver and xset q. However, the screen blanks after about 30 seconds. If I turn off DPMS (either via xscreensaver GUI or modifying ~/.xscreensaver), it won't blank at all, so I know that DPMS is partially reading the xscreensaver settings. -- edit I've attempted more troubleshooting, by creating a new user account, then logging out of the main account and into the new account. I've tried modifying the timeouts via dconf, but get the same results as above (i.e. it doesn't work, nor does sleep-display-ac, but idle-dim-time and idle-dim-ac work). Also, the depreciated sleep-display-ac key is not visible, so I think that this is probably unrelated. -- edit I've since moved to gnome-shell instead of unity, and still have this problem, so I guess that it's something to do with gnome-power-manager.

• How do you manage extensibility in your multi-tenant systems?

  - by Brian MacKay

  I've got a few big web based multi-tenant products now, and very soon I can see that there will be a lot of customizations that are tenant specific. An extra field here or there, maybe an extra page or some extra logic in the middle of a workflow - that sort of thing. Some of these customizations can be rolled into the core product, and that's great. Some of them are highly specific and would get in everyone else's way. I have a few ideas in mind for managing this, but none of them seem to scale well. The obvious solution is to introduce a ton of client-level settings, allowing various 'features' to be enabled on per-client basis. The downside with that, of course, is massive complexity and clutter. You could introduce a truly huge number of settings, and over time various types of logic (presentation, business) could get way out of hand. Then there's the problem of client-specific fields, which begs for something cleaner than just adding a bunch of nullable fields to the existing tables. So what are people doing to manage this? Force.com seems to be the master of extensibility; obviously they've created a platform from the ground up that is super extensible. You can add on to almost anything with their web-based UI. FogBugz did something similiar where they created a robust plugin model that, come to think of it, might have actually been inspired by Force. I know they spent a lot of time and money on it and if I'm not mistaken the intention was to actually use it internally for future product development. Sounds like the kind of thing I could be tempted to build but probably shouldn't. :) Is a massive investment in pluggable architecture the only way to go? How are you managing these problems, and what kind of results are you seeing? EDIT: It does look as though FogBugz handled the problem by building a fairly robust platform and then using that to put together their screens. To extend it you create a DLL containing classes that implement interfaces like ISearchScreenGridColumn, and that becomes a module. I'm sure it was tremendously expensive to build considering that they have a large of devs and they worked on it for months, plus their surface area is perhaps 5% of the size of my application. Right now I am seriously wondering if Force.com is the right way to handle this. And I am a hard core ASP.Net guy, so this is a strange position to find myself in.

• WebSocket API 1.1 released!

  - by Pavel Bucek

  Its my please to announce that JSR 356 – Java API for WebSocket maintenance release ballot vote finished with majority of “yes” votes (actually, only one eligible voter did not vote, all other votes were “yeses”). New release is maintenance release and it addresses only one issue:  WEBSOCKET_SPEC-226. What changed in the 1.1? Version 1.1 is fully backwards compatible with version 1.0, there are only two methods added to javax.websocket.Session: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 /** * Register to handle to incoming messages in this conversation. A maximum of one message handler per * native websocket message type (text, binary, pong) may be added to each Session. I.e. a maximum * of one message handler to handle incoming text messages a maximum of one message handler for * handling incoming binary messages, and a maximum of one for handling incoming pong * messages. For further details of which message handlers handle which of the native websocket * message types please see {@link MessageHandler.Whole} and {@link MessageHandler.Partial}. * Adding more than one of any one type will result in a runtime exception. * * @param clazz   type of the message processed by message handler to be registered. * @param handler whole message handler to be added. * @throws IllegalStateException if there is already a MessageHandler registered for the same native *                               websocket message type as this handler. */ public void addMessageHandler(Class<T> clazz, MessageHandler.Whole<T> handler); /** * Register to handle to incoming messages in this conversation. A maximum of one message handler per * native websocket message type (text, binary, pong) may be added to each Session. I.e. a maximum * of one message handler to handle incoming text messages a maximum of one message handler for * handling incoming binary messages, and a maximum of one for handling incoming pong * messages.

Short and not precise version: to support Lambda expressions as MessageHandlers. Longer and slightly more precise explanation: old Session#addMessageHandler method (which is still there and works as it worked till now) does rely on getting the generic parameter during the runtime, which is not (always) possible. The unfortunate part is that it works for some common cases and the expert group did not catch this issue before 1.0 release because of that. The issue is really clearly visible when Lambdas are used as message handlers: 1 2 3 session.addMessageHandler(message -> { System.out.println("### Received: " + message); }); There is no way for the JSR 356 implementation to get the type of the used Lambda expression, thus this call will always result in an exception. Since all modern IDEs do recommend to use Lambda expressions when possible and MessageHandler interfaces are single method interfaces, it basically just scream “use Lambdas” all over the place but when you do that, the application will fail during runtime. Only solution we currently have is to explicitly provide the type of registered MessageHandler. (There might be another sometime in the future when generic type reification is introduced, but that is not going to happen soon enough). So the example above will then be: 1 2 3 session.addMessageHandler(String.class, message -> { System.out.println("### Received: " + message); }); and voila, it works. There are some limitations – you cannot do 1 List<String>.class , so you will need to encapsulate these types when you want to use them in MessageHandler implementation (something like “class MyType extends ArrayList<String>”). There is no better way how to solve this issue, because Java currently does not provide good way how to describe generic types. The api itself is available on maven central, look for javax.websocket:javax.websocket-api:1.1. The reference implementation is project Tyrus, which implements WebSocket API 1.1 from version 1.8.

• Cloud service and IM protocol advice, for a backend to group chat mobile app

  - by Jonathan

  Overview I’m going to develop an app on Android and iOS. It will allow users to set up group ‘chat rooms’ and talk on chat rooms set up by other users. The service needs to be highly scalable, such that it could accommodate a massive increase in users overnight (we can only dream). Chat requirements The chat protocol used should be flexible: it should allow me to determine who can view/post on ‘chat rooms’ based on certain other factors, as determined by the first poster/creator of the particular ‘chat room’. It should also allow for users to simply install the app and begin using the service, after only providing a simple nickname (which could be changed later). Chat protocol plans Having looked around I think the XMPP protocol is the best candidate. In particular the Multi-user chat extension looks like what I’ll need. Would this be most suited to my requirements, or do you know another potential solution? Cloud service I have been deciding between Amazon Web Services, Google App Engine and Windows Azure. I’m coming to the conclusion that Azure will be best, as it is easier to manage than AWS (ease of scalability will be a key factor in the design), I think it may be less restricted than GAE, plus Azure will soon have toolkits to allow easy interfacing with both Android and iOS phones. Is this the decision you would have made, or would you recommend/look into other cloud services? General project philosophy I have only recently started looking into this project’s feasibility, and am no expert on any of its aspects. So wherever possible I will leave the actual implementations to experts, i.e. choosing a higher-level cloud service, using a well-documented plugin of a, proven reliable, group chat protocol etc. My background I have some programming knowledge from a computer science degree. Main languages I’ve used have been Java and Python, but I don’t want this to affect design decisions for the project. The most appropriate languages for the task should be used, i.e. I don’t mind learning a lot of new skills (my current programming levels are relatively basic anyway). Thank you Thanks for reading, and any advice you have about any aspect would be greatly appreciated :-)

• Issue 56 - Super Stylesheets Skinning in DotNetNuke 5

  May 2010 Welcome to Issue 56 of DNN Creative Magazine In this issue we show you how to use the powerful new Super Stylesheets skinning feature in DotNetNuke 5. Super Stylesheets are ideal for both beginner and experienced skin designers, they provide skin layouts using CSS. The advantage of Super Stylesheets is that you can easily create a skin layout which works in all browsers without the need to learn complex CSS techniques. They are also very quick to build and you can change a skin layout in a matter of minutes rather than hours. We show you how to build a skin from the very beginning using Super Stylesheets, we show you how to create various skin layouts, as well as multi-layouts. We also show you how to style the skin, how to add tokens such as the logo, menu, login links etc. and walk you through how to create a fully working skin from scratch. Following this we continue the Open Web Studio tutorials, this month we demonstrate how to create an installable DotNetNuke PA module using OWS. This is an essential technique which allows you to package up the OWS applications that you have created and build them into an installable zip package. The zip file is then installable as a standard DotNetNuke module which means you can easily install your OWS applications on other DotNetNuke installations by simply installing them as a standard DotNetNuke module. To finish, we have part six of the "How to Build a News Application with DotNetMushroom Rapid Application Developer (RAD)" article, where we demonstrate how to create a News Carousel using RAD, JQuery and the JCarousel plugin.

• Why would more CPU cores on virtual machine slow compile times?

  - by Sid

  [edit#2] If anyone from VMWare can hit me up with a copy of VMWare Fusion, I'd be more than happy to do the same as a VirtualBox vs VMWare comparison. Somehow I suspect the VMWare hypervisor will be better tuned for hyperthreading (see my answer too) I'm seeing something curious. As I increase the number of cores on my Windows 7 x64 virtual machine, the overall compile time increases instead of decreasing. Compiling is usually very well suited for parallel processing as in the middle part (post dependency mapping) you can simply call a compiler instance on each of your .c/.cpp/.cs/whatever file to build partial objects for the linker to take over. So I would have imagined that compiling would actually scale very well with # of cores. But what I'm seeing is: 8 cores: 1.89 sec 4 cores: 1.33 sec 2 cores: 1.24 sec 1 core: 1.15 sec Is this simply a design artifact due to a particular vendor's hypervisor implementation (type2:virtualbox in my case) or something more pervasive across more VMs to make hypervisor implementations more simpler? With so many factors, I seem to be able to make arguments both for and against this behavior - so if someone knows more about this than me, I'd be curious to read your answer. Thanks Sid [edit:addressing comments] @MartinBeckett: Cold compiles were discarded. @MonsterTruck: Couldn't find an opensource project to compile directly. Would be great but can't screwup my dev env right now. @Mr Lister, @philosodad: Have 8 hw threads, using VirtualBox, so should be 1:1 mapping without emulation @Thorbjorn: I have 6.5GB for the VM and a smallish VS2012 project - it's quite unlikely that I'm swapping in/out trashing the page file. @All: If someone can point to an open source VS2010/VS2012 project, that might be a better community reference than my (proprietary) VS2012 project. Orchard and DNN seem to need environment tweaking to compile in VS2012. I really would like to see if someone with VMWare Fusion also sees this (for VMWare vs VirtualBox compartmentalization) Test details: Hardware: Macbook Pro Retina CPU : Core i7 @ 2.3Ghz (quad core, hyper threaded = 8 cores in windows task manager) Memory : 16 GB Disk : 256GB SSD Host OS: Mac OS X 10.8 VM type: VirtualBox 4.1.18 (type 2 hypervisor) Guest OS: Windows 7 x64 SP1 Compiler: VS2012 compiling a solution with 3 C# Azure projects Compile times measure by VS2012 plugin called 'VSCommands' All tests run 5 times, first 2 runs discarded, last 3 averaged

• Managing Joomla via Android

  Surprisingly, it was only today that I actually looked for possible solutions to write more content for my blog. Since quite some time I'm using my Samsung Galaxy Tab 10.1 for all kind of social media activities like Google+, FB, etc. but also for my casual mail during the evening hours. And yes, I feel a little bit guilty about missing the chance to use my tablet to write some content here... OK, only a little bit. ;-) These are not the droids you are looking for But those lazy times are over! While searching the Play Store with the expression 'joomla' I got three interesting hits: - Joomla Admin Mobile! - Joooid - Joomla! Security Checklist After reading the reviews I installed the two later apps. Joomla! Security Checklist The author clearly outlines here that the app is primarily for his personal purpose to have safety checklist at hand at anytime. I guess that any reader of this article has an Android based smartphone or tablet, so that simple app should be part of your toolbox when using Joomla! for your websites. Joooid plugin & app Although I was looking for an app that could work with the default XML RPC interface of Joomla I have to admit that this combination of an enhanced Web service suits me better, mainly due to performance reason. The official website has not only the downloads for Joomla versions 1.5 - 2.5 but also very good and easy to follow step-by-step instructions to prepare your server for the Android app. It will take you less than 5 minutes to get it up and running. For safety reasons, I recommend that you should configure your Web server to have an additional authentication layer on the plugins folder. The smartphone app has the ability to run against HTTP authentication. Personally, I like the look and feel of the app. It is a little bit different compared to the web UI but still easy to use. In fact, this article is the first one written in the Joooid app. At the moment, I only miss the ability to have list tags. Quick and easy Writing full-fledged articles with images, a couple of hyperlinks and some styling here and there should be left to the desktop. At least for the moment. Let's see whether I'm going to change my mind on this during the upcoming months... I'll give it a try, and hope to publish at least once per month to write some content using Joooid. Actually, it would be great to have some feedback about other Joomla! clients in the wild.

• Develop web site from existing software or cherry pick and use a web framework?

  - by erisco

  A small team and I are tasked with developing a web site. The client has referenced a particular open source project (we'll call it X) when describing some of the features. Because of this, the team wants to start with X and adapt it to satisfy the client. I have looked at X and its code and, in my opinion, it would be unwise. However, my experience is limited, and could really benefit from the insights of others so that I can figure out what I should be asserting as the right direction for the team. My red flags are going up and this is why. X was developed in the earlier days of PHP; 500 line blocks of code are the norm; global variables are abundant; giant switch cases are the norm for switching between which page is shown. There is no clear mapping between URL and where the code for that page sits. From a feature-set standpoint, X is actually software specialized for a different task and has dozens of features we don't need or have use for that come as core assumptions. We will be unable to adapt X through its plugin system. That said, there are a few features which can be mapped, with some modification, to suit our purposes. I believe this is the attraction the team feels. I would feel comfortable if, instead of using X directly, we lifted what is salvageable and useful to us. We can then use that code, and the same 3rd party libraries X is using, in a new code base built on top of a PHP web framework (particularly Agavi, so you understand what I mean by 'web framework'). The web framework gives us a strong MVC structure and provides the common facilities for web development, or adapters to work with 3rd party libraries that do so. We will also have a clean slate feature-wise to work from, which means we can work additively instead of subtractively. Because the code base is better structured, and contains none of what we don't need, it will be easier to document, which is a critical requirement of our client. So to summarize, the team wants to use X, whereas I want to take the bits we can from X and use a web framework instead. I want to bounce this opinion off of other's experiences so that I can be more informed. Thanks for your insight.

• Block-level deduplicating filesystem

  - by James Haigh

  I'm looking for a deduplicating copy-on-write filesystem solution for general user data such as /home and backups of it. It should use online/inline/synchronous deduplication at the block-level using secure hashing (for negligible chance of collisions) such as SHA256 or TTH. Duplicate blocks need not even touch the disk. The idea is that I should be able to just copy /home/<user> to an external HDD with the same such filesystem to do a backup. Simple. No messing around with incremental backups where corruption to any of the snapshots will nearly always break all later snapshots, and no need to use a specific tool to delete or 'checkout' a snapshot. Everything should simply be done from the file browser without worry. Can you imagine how easy this would be? I'd never have to think twice about backing-up again! I don't mind a performance hit, reliability is the main concern. Although, with specific implementations of cp, mv and scp, and a file browser plugin, these operations would be very fast, especially when there is a lot of duplication as they would only need to transfer the absent blocks. Accidentally using conventional copy tools that do not integrate with the FS would merely take longer, waste some bandwidth when copying remotely and waste some CPU, as the duplicate data would be re-read, re-transferred and re-hashed (although nothing would be re-written), but would absolutely not corrupt anything. (Some filesharing software may also be able to benefit by integrating with the FS.) So what's the best way of doing this? I've looked at some options: lessfs - Looks unmaintained. Any good? [Opendedup/SDFS][3] - Java? Could I use this on Android?! What does [SDFS][4] stand for? [Btrfs][5] - Some patches floating around on mailing list archives, but no real support. [ZFS][6] - Hopefully they'll one day relicense under a true Free/Opensource GPL-compatible licence. Also, 2 years ago I had a go at an attempt in Python using Fuse at the file-level to be used over the top of a typical solid FS such as EXT4, but I found Fuse for Python underdocumented and didn't manage to implement all of the system calls. My first post here, so I can't post more than 2 links until I get over 10 rep: [3]: http://www.opendedup.org/ [4]: https://en.wikipedia.org/w/index.php?title=SDFS&action=edit&redlink=1 [5]: https://en.wikipedia.org/wiki/Btrfs#Features [6]: https://en.wikipedia.org/wiki/ZFS#Linux

• My 2011 Professional Development Goals

  - by kerry

  I thought it might be a good idea to post some professional goals for 2011.  Hopefully, I can look at this list at the end of the year and have accomplished most of them. Release an Android app to the marketplace – I figured I would put this first because I have one that I have been working on for a while and it is about ready.  Along with this, I would like to start another one and continue to develop my Android skills. Contribute free software to the community – Again, I have an SMF plugin that will fill this requirement nicely.  Just need to give it some polish and release it.  That’s not all, I would like to add a few more libraries on github, or possibly contribute to an open source project. Regularly attend a user group meetings outside of Java – A great way to meet people and learn new things. Obtain the Oracle Certified Web Developer Certification – I got the SCJP a few years ago and would like to obtain another one.  One step closer to Certified Enterprise Architect. Learn scala – As a language geek, I like to stick to the Pragmatic Programmer’s ‘learn a new language every year’ rule (last year was Ruby).  Scala presents some new concepts all wrapped in a JVM-based OOP language.  Time to dig in. Write an app using JSF – New JEE 6 features are pretty slick.  I want to really leverage them in an app. Present at a user group meeting – Last but not least, I would like to improve my public speaking and skills in presenting.  Also, is a great reason to dig in to some latest and greatest tech. Use git more, and more effectively – Trying to move all my personal projects from Subversion to Git. That’s it.  A little daunting, but I am confident I can at least touch on most of these and it’s a great roadmap to my professional development.

• RTS Game Style Application [closed]

  - by Daniel Wynand van Wyk

  My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!
