• Ed Burns' Servlet 4/HTTP 2 Session at JavaOne 2014

  - by reza_rahman

  For the Java EE track at JavaOne 2014 we are highlighting some key sessions and speakers to better inform you of what you can expect, right up until the start of the conference. To this end we recently interviewed Ed Burns. Ed is a veteran of Sun and now Oracle. He has been and is instrumental in pushing the JSF ecosystem forward as specification lead. Besides his specification lead work Ed is well regarded as an author and speaker on his own right. In addition to carrying the JSF torch Ed will be co-leading the key Servlet 4 specification for Java EE 8, along with Servlet specification guru Shing Wai Chan. The primary goal of Servlet 4 is to enable the fundamentally important changes in HTTP 2 for the entire server-side Java ecosystem. We wanted to talk to Ed about his Servlet 4 session at JavaOne 2014 and HTTP 2 generally: The details for the Servlet 4 session can be found here. Ed has several other key sessions on the track that we hope to talk to him about separately in the near future: What’s Next for JSF?: In this key session, Ed will be sharing the next steps for the continued evolution of the JSF specification in Java EE 8. Where’s My UI? The 2014 JavaOne Web App UI Smackdown: The UI space for web applications, especially in the Java ecosystem continues to be as hotly contested as ever. This is especially true with the (re)introduction of JavaScript based rich client frameworks like AngularJS. This lively panel brings together experts representing the diverse schools of thought for web UIs. Ed will be representing JSF of course. Neal Ford will moderate the panel as an independent and hopefully reasonably neutral party. Adopt-a-JSR for Java EE 7 and Java EE 8: Adopt-a-JSR has been a reasonable success for Java EE 7. With Java EE 8 we are planning to strengthen it far more as away of getting grassroots level participation in the specification efforts. This session will introduce Adopt-a-JSR, share how it worked for Java EE 7 and what we plan to do with it in Java EE 8. Ed will be sharing his perspectives on Adopt-a-JSR for both Java EE 7 and Java EE 8. Besides Ed's sessions, we have a very strong program for the Java EE track and JavaOne overall - just explore the content catalog. If you can't make it, you can be assured that we will make key content available after the conference just as we have always done.

• Handling permissions in a MVP application

  - by Chathuranga

  In a windows forms payroll application employing MVP pattern (for a small scale client) I'm planing user permission handling as follows (permission based) as basically its implementation should be less complicated and straight forward. NOTE : System could be simultaneously used by few users (maximum 3) and the database is at the server side. This is my UserModel. Each user has a list of permissions given for them. class User { string UserID { get; set; } string Name { get; set; } string NIC {get;set;} string Designation { get; set; } string PassWord { get; set; } List <string> PermissionList = new List<string>(); bool status { get; set; } DateTime EnteredDate { get; set; } } When user login to the system it will keep the current user in memory. For example in BankAccountDetailEntering view I control the controller permission as follows. public partial class BankAccountDetailEntering : Form { bool AccountEditable {get; set;} private void BankAccountDetailEntering_Load(object sender, EventArgs e) { cmdEditAccount.enabled = false; OnLoadForm (sender, e); // Event fires... If (AccountEditable ) { cmdEditAccount.enabled=true; } } } In this purpose my all relevant presenters (like BankAccountDetailPresenter) should aware of UserModel as well in addition to the corresponding business Model it is presenting to the View. class BankAccountDetailPresenter { BankAccountDetailEntering _View; BankAccount _Model; User _UserModel; DataService _DataService; BankAccountDetailPresenter( BankAccountDetailEntering view, BankAccount model, User userModel, DataService dataService ) { _View=view; _Model = model; _UserModel = userModel; _DataService = dataService; WireUpEvents(); } private void WireUpEvents() { _View.OnLoadForm += new EventHandler(_View_OnLoadForm); } private void _View_OnLoadForm(Object sender, EventArgs e) { foreach(string s in _UserModel.PermissionList) { If( s =="CanEditAccount") { _View.AccountEditable =true; return; } } } public Show() { _View.ShowDialog(); } } So I'm handling the user permissions in the presenter iterating through the list. Should this be performed in the Presenter or View? Any other more promising ways to do this? Thanks.

• The Windows 8 and Ubuntu 12.04 Dual Boot NIghtmare

  - by Steve

  I have done some research as to how to go about this dual-boot, and I am close, but I need some guidance with booting into Windows 8 (Ubuntu is installed). I have a Lenovo Ideapad y510p. I will go over what I have done to dual-boot this laptop, with windows 8 pre-installed, with Ubuntu 12.04: I followed every instruction to the letter for the 97-vote response here, and everything worked fine up until after the repair boot section: Installing on a Pre-Installed Windows 8 System (UEFI Supported) I ran into the following error upon restarting after the repair boot section: error: invalid arch independent elf magic. This error (a grub issue) disabled me from booting into Ubuntu :( After a little googling, I followed the instructions in the reactivating grub 2 section to resolve the error: http://kb.acronis.com/content/1686 I found a possible solution to fixing the Windows 8 boot issue, and tried it: http://webcache.googleusercontent.com/search?q=cache:i9JMyXzzRpYJ:askubuntu.com/questions/279275/dual-boot-problem-windows-8-ubuntu-12-04+&cd=1&hl=en&ct=clnk&gl=us&client=ubuntu I thought the above solution worked, but when I attempt to boot into Windows 8, I get the following missing file error: File: \Boot\BCD Status: 0xc000000e Info: The Boot Configuration Data for your PC is missing or contains errors. Here is some other information that may be useful: I have 3 partitions devoted to Ubuntu. The first, sda8, has a flag bios_grub (1049 kb). The second, sda9, is where everything else is (96.6 GB). The last, sda10, is for swap (8299 MB). My question is: How do I fix the boot configuration for Windows 8? Any help would be greatly appreciated :) Update 1: When I attempt to boot into UEFI mode, I get the following error: invalid arch independent elf magic (the same error I saw in step 2). Update 2: A useful link here I found: Dual booting Ubuntu 12.04: UEFI and Legacy So, this is my 4th time installing Ubuntu on the laptop, and it looks like I need to install it in UEFI mode. Should I scrap it all again, and reinstall? Or is there ANY way of salvaging my installation? At this point, I can't even boot into Windows (although I have an installation cd to fix the windows boot issue, that would ultimately screw over ubuntu). Update 3: After doing a little more browsing around, I found a cool way around this messy grub stuff, using rEFInd. Rod Smith's post here saved me! Installing ubuntu 12.04.02 in uefi mode Now, I am able to dual-boot Windows 8 and Ubuntu and boot into both operating systems :) I have another issue (relating to the boot configuration in the bios) that I will post as a separate question :)

• Securing User Account Details with MySQL

  - by Antoinette O'Sullivan

  Keeping user account details secure is always at the forefront of a Database Administrator's mind. However, users want to get up and running as soon as possible without complex login procedures. You can learn more about this and many other topics in the MySQL for Database Administrator course. For example, MySQL 5.6.6 introduced a new utility: mysql_config_editor, which makes secure access via MySQL client applications much easier to establish, while still providing a good measure of security. The mysql_config_editor stores a user's authentication details in an encrypted login file called mylogin.cnf. This login file is readable and writable for the user who invokes the utility, and invisible to everyone else. You can use it to collect all your hard-to-remember server locations and paswords safe in the knowledge that your passwords are never invoked using clear text. The MySQL for Database Administrators course is a 5-day instructor-led course which is available as a: Training-on-Demand: Start training within 24 hours of registration, following lecture material at your own pace through streaming video and booking time on a lab environment to suit your schedule. Live-Virtual Event: Attend a live event from your own desk, choosing from a selection of events on the schedule to suit different timezones.

• Programming and Ubiquitous Language (DDD) in a non-English domain

  - by Sandor Drieënhuizen

  I know there are some questions already here that are closely related to this subject but none of them take Ubiquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with mixed languages anyway. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options? UPDATE Today, about year later, having dealt with this issue on a daily basis, I have to say that option 3 has worked out pretty well for me. It wasn't as tedious as I initially feared and translating in real time while talking to the client wasn't a problem either. I also found the following advantages to be true, based on my experience. Translating the UL makes you pay more attention to defining the UL and even the domain itself, especially when you don't know how to translate a term and you have to start looking through dictionaries etc. This has even caused me to reconsider domain modeling decisions a few times. It helps you make your knowledge of the English language more profound. Obviously, your code is much more pleasant to look at instead of being a mind boggling obscenity.

• JWT Token Security with Fusion Sales Cloud

  - by asantaga

  When integrating SalesCloud with a 3rd party application you often need to pass the users identity to the 3rd party application so that  The 3rd party application knows who the user is The 3rd party application needs to be able to do WebService callbacks to Sales Cloud as that user.  Until recently without using SAML, this wasn't easily possible and one workaround was to pass the username, potentially even the password, from Sales Cloud to the 3rd party application using URL parameters.. With Oracle Fusion R8 we now have a proper solution and that is called "JWT Token support". This is based on the industry JSON Web Token standard , for more information see here JWT Works by allowing the user the ability to generate a token (lasts a short period of time) for a specific application. This token is then passed to the 3rd party application as a GET parameter.  The 3rd party application can then call into SalesCloud and use this token for all webservice calls, the calls will be executed as the user who generated the token in the first place, or they can call a special HR WebService (UserService-findSelfUserDetails() ) with the token and Fusion will respond with the users details. Some more details  The following will go through the scenario that you want to embed a 3rd party application within a WebContent frame (iFrame) within the opportunity screen.  1. Define your application using the topology manager in setup and maintenance  See this documentation link on topology manager 2. From within your groovy script which defines the iFrame you wish to embed, write some code which looks like this : def thirdpartyapplicationurl = oracle.topologyManager.client.deployedInfo.DeployedInfoProvider.getEndPoint("My3rdPartyApplication" )def crmkey= (new oracle.apps.fnd.applcore.common.SecuredTokenBean().getTrustToken())def url = thirdpartyapplicationurl +"param1="+OptyId+"&jwt ="+crmkeyreturn (url)  This snippet generates a URL which contains The Hostname/endpoint of the 3rd party application Two Parameters The opportunityId stored in parameter "param1" The JWT Token store in  parameter "jwt" 3. From your 3rd Party Application you now have two options Execute a webservice call by first setting the header parameter "Authentication" to the JWT token. The webservice call will be executed against Fusion Applications "As" the user who execute the process To find out "Who you are" , set the header parameter to "Authentication" and execute the special webservice call findSelfUserDetails(), in the UserDetailsService For more information  Oracle Sales Cloud Documentation , specific chapter on JWT Token OTN samples, specifically the Rich UI With JWT Token Sample Oracle Fusion Applications General Documentation

• Remote synchronization

  - by Tomas Mysik

  Hi all, today we would like to show you another improvement we have prepared for NetBeans 7.2. Today, let's talk a little bit about remote synchronization. If you already use our simple (S)FTP client, this enhancement could be useful for you. Simply right click on Source Files and select Synchronize. Please notice that the remote synchronization works better only on the whole project (it means that the Source Files must be selected). The Synchronize action is also available on individual files (more files can be selected at once) but the suggested operation (download, upload etc.) does not work so precisely. Also please notice that the suggested operations are not 100% reliable since the timestamps provided by FTP servers are not exact. Once the remote files (their names and paths only, of course) are fetched, the main dialog appears: As you can see, NetBeans tries to suggest you operations (upload, download etc.) which should be done for each individual file of your project. If you are interested only in some particular changes, you can simply filter the list: Since we have a file conflict, we need to resolve it first. Fortunately this is very easy because we just select the desired file and click the Diff button . The remote version of our file is downloaded and compared with the local version. The resut is displayed in the dialog where you can easily apply and/or refuse the remote changes or even simply type manually to the local version of the selected file: Once we are done with our changes, the operation for the selected file changes to Upload and the file is marked with * (since we made some changes). Please notice that if you now click the Cancel button, in fact no changes are done in our local file. As you can see, if we have one or more files selected, we can change their operation to: no operation (file won't be synchronized) download upload delete (both local and remote file) reset (the operation is resetted to the original one suggested by NetBeans and also all changes done via Diff action are discarded) Now we are ready to synchronize our project. NetBeans will show us the synchronization summary (this dialog can be omitted, see the Show Summary checkbox on the previous image). The synchronization itself starts and we can see its progress and of course its result. As always, all the operations can be reviewed in the Output window. That's all for today, as always, please test it and report all the issues or enhancements you find in NetBeans BugZilla (component php, subcomponent FTP support).

• Review: Backbone.js Testing

  - by george_v_reilly

  Title: Backbone.js Testing Author: Ryan Roemer Rating: $stars(4.5) Publisher: Packt Copyright: 2013 ISBN: 178216524X Pages: 168 Keywords: programming, testing, javascript, backbone, mocha, chai, sinon Reading period: October 2013 Backbone.js Testing is a short, dense introduction to testing JavaScript applications with three testing libraries, Mocha, Chai, and Sinon.JS. Although the author uses a sample application of a personal note manager written with Backbone.js throughout the book, much of the material would apply to any JavaScript client or server framework. Mocha is a test framework that can be executed in the browser or by Node.js, which runs your tests. Chai is a framework-agnostic TDD/BDD assertion library. Sinon.JS provides standalone test spies, stubs and mocks for JavaScript. They complement each other and the author does a good job of explaining when and how to use each. I've written a lot of tests in Python (unittest and mock, primarily) and C# (NUnit), but my experience with JavaScript unit testing was both limited and years out of date. The JavaScript ecosystem continues to evolve rapidly, with new browser frameworks and Node packages springing up everywhere. JavaScript has some particular challenges in testing—notably, asynchrony and callbacks. Mocha, Chai, and Sinon meet those challenges, though they can't take away all the pain. The author describes how to test Backbone models, views, and collections; dealing with asynchrony; provides useful testing heuristics, including isolating components to reduce dependencies; when to use stubs and mocks and fake servers; and test automation with PhantomJS. He does not, however, teach you Backbone.js itself; for that, you'll need another book. There are a few areas which I thought were dealt with too lightly. There's no real discussion of Test-driven_development or Behavior-driven_development, which provide the intellectual foundations of much of the book. Nor does he have much to say about testability and how to make legacy code more testable. The sample Notes app has plenty of testing seams (much of this falls naturally out of the architecture of Backbone); other apps are not so lucky. The chapter on automation is extremely terse—it could be expanded into a very large book!—but it does provide useful indicators to many areas for exploration. I learned a lot from this book and I have no hesitation in recommending it. Disclosure: Thanks to Ryan Roemer and Packt for a review copy of this book.

• If unexpected database changes cause you problems – we can help!

  - by Chris Smith

  Have you ever been surprised by an unexpected difference between you database environments? Have you ever found that your Staging database is not the same as your Production database, even though it was the week before? Has an emergency hotfix suddenly appeared in Production over the weekend without your knowledge? Has your client secretly added a couple of indices to their local version of the database to aid performance? Worse still, has a developer ever accidently run a SQL script against the wrong database without noticing their mistake? If you’ve answered “Yes” to any of the above questions then you’ve suffered from ‘drift’. Database drift is where the state of a database (schema, particularly) has moved away from its expected or official state over time. The upshot is that the database is in an unknown or poorly-understood state. Even if these unexpected changes are not destructive, drift can be a big problem when it’s time to release a new version of the database. A deployment to a target database in an unexpected state can error and fail, potentially delaying a vital, time-sensitive update. A big issue with drift is that it can be hard to spot and it can be even harder to determine its provenance. So, before you can deal with an issue caused by drift, you’ll need to know exactly what change has been made, who made it, when they made it and why they made it. Those questions can take a lot of effort to answer. Then you actually need to decide what to do. Do you rollback the change because it was bad? Retrospectively apply it to the Staging environment because it is a required change? Or script the change into version control to get it back in line with your process? Red Gate’s Database Delivery Team have been talking to DBAs, database consultants and database developers to explore the problem of drift. We’ve started to get a really good idea of how big a problem it can be and what database professionals need to know and do, in order to deal with it.  It’s fair to say, we’re pretty excited at the prospect of creating a tool that will really help and we’ve got some great feedback on our initial ideas (see image below).   We’re now well underway with the development of our new drift-spotting product – SQL Lighthouse – and we hope to have a beta release out towards the end of July. What we really need is your help to shape the product into a great tool. So, if database drift is a problem that you’d like help solving and are interested in finding out more about our product, join our mailing list to register your interest in trying out the beta release.

• ADF Code Guidelines

  - by Chris Muir

  During Oracle Open World 2012 the ADF Product Management team announced a new OTN website, the ADF Architecture Square.  While OOW represents a great opportunity to let customers know about new and exciting developments, the problem with making announcements during OOW however is customers are bombarded with so many messages that it's easy to miss something important. So in this blog post I'd like to highlight as part of the ADF Architecture Square website, one of the initial core offerings is a new document entitled ADF Code Guidelines. Now the title of this document should hopefully make it obvious what the document contains, but what's the purpose of the document, why did Oracle create it? Personally having worked as an ADF consultant before joining Oracle, one thing I noted amongst ADF customers who had successfully deployed production systems, that they all approached software development in a professional and engineered way, and all of these customers had their own guideline documents on ADF best practices, conventions and recommendations.  These documents designed to be consumed by their own staff to ensure ADF applications were "built right", typically sourced their guidelines from their team's own expert learnings, and the huge amount of ADF technical collateral that is publicly available.  Maybe from manuals and whitepapers, presentations and blog posts, some written by Oracle and some written by independent sources. Now this is all good and well for the teams that have gone through this effort, gathering all the information and putting it into structured documents, kudos to them.  But for new customers who want to break into the ADF space, who have project pressures to deliver ADF solutions without necessarily working on assembling best practices, creating such a document is understandably (regrettably?) a low priority.  So in recognising this hurdle, at Oracle we've devised the ADF Code Guidelines.  This document sets out ADF code guidelines, practices and conventions for applications built using ADF Business Components and ADF Faces Rich Client (release 11g and greater).  The guidelines are summarized from a number of Oracle documents and other 3rd party collateral, with the goal of giving developers and development teams a short circuit on producing their own best practices collateral. The document is not a final production, but a living document that will be extended to cover new information as discovered or as the ADF framework changes. Readers are encouraged to discuss the guidelines on the ADF EMG and provide constructive feedback to me (Chris Muir) via the ADF EMG Issue Tracker. We hope you'll find the ADF Code Guidelines useful and look forward to providing updates in the near future. Image courtesy of paytai / FreeDigitalPhotos.net

• Silverlight Cream for March 07, 2011 -- #1055

  - by Dave Campbell

  In this Issue: Max Paulousky, Chris Rouw, David Anson, Jesse Liberty, Shawn Wildermuth, Simon Guindon, and Dhananjay Kumar. Above the Fold: Silverlight: "Faster Databinding in WPF and Silverlight using OptimizedObservableCollection" Simon Guindon WP7: "Phoney Tools Updated (WP7 Open Source Library)" Shawn Wildermuth From SilverlightCream.com: Problems With Sharing Windows Phone 7 Applications Within A Large Group Of Beta Testers Max Paulousky has a post up discussing the issues surrounding beta testing a WP7 app with a large group of testers... and how to pull it all off. WP7 Insights #1: Consuming REST APIs within a WP7 app Chris Rouw is beginning a WP7 series based on his recent experience of getting a client's app into the marketplace. This first in his series is on consuming REST APIs ... lots of good code and explanations. Improving Windows Phone 7 application performance is even easier with these LowProfileImageLoader and DeferredLoadListBox updates David Anson has an update to his LowProfileImageLoader and DeferredLoadListBox after issues brought up by readers... so we all win with the great feedback from alert devs. When Isolated Storage Isn’t Enough Jesse Liberty started looking at Jeremy Likness' Sterling with this post in the WP7 From Scratch series. He starts with downloading it from CodePlex ... great way to get into Sterling if you haven't already. Phoney Tools Updated (WP7 Open Source Library) Shawn Wildermuth has the latest drop of his Phoney Tools up... this is the last Alpha. I've added a tag for it as well. He's fixed some things, added others... check out the post and go grab the code. Faster Databinding in WPF and Silverlight using OptimizedObservableCollection Simon Guindon is a blogger I've not been following, but this post on an OptimizedObservableCollection caught my eye. He added an AddRange() to the ObservableCollection to get a speed enhancement when adding items... and a pretty good speed enhancement it is. Reading files asynchronously using WebClient class in Silverlight Dhananjay Kumar is another prolific blogger that I've not been following, so we'll start with his latest... a step-by-step guide to reading an XML file asynchronously.

• Web 2.0 Solutions with Oracle WebCenter 11g &ndash; Book Review

  - by juan.ruiz

  Recently I obtained a copy of the book Web 2.0 Solutions with Oracle Web Center 11g from Packt Publishing, right away I noticed that one of the authors of this book is a good and long time colleague of  mine Plinio Arbizu, whom I have joined for different developer events in Latin America in the past. In this entry you will find my review of the book. Chapter 1: What's Oracle WebCenter? Provides you with basic knowledge to understand the pieces of WebCenter and the role that these pieces play in the overall Oracle Fusion Middleware strategy. Chapter 2 and 3: Will guide you through installation process and set up instructions, required to start developing Web2.0 applications. The screenshots are very helpful. Chapter 4: The chapter will guide you through a series of steps for creating a basic HelloWorld application that uses ADF/Webservices/WebCenter framework to understand the relevant pieces that are part of the architecture in large Web2.0 solutions for WebCenter. One caveat on this chapter is that the use HTML in combination with ADF Faces is not a recommended practice, because in some cases (not in this one) HTML code generated by the components can conflict with existent HTML code place on the same page... so be careful. Chapter 5: Describes the basics to understand the usage of ADF Faces Rich Client Components, with templates and ADF Business components. Chapter 6: This chapter explains how to encapsulate, deploy and consume ADF UIs as JSR 168 portlets in a declarative way Chapter 7: Explains some of the WebCenter services and the different ways that these services can be integrated within WebCenter applications. Chapter 8: Goes over how to include a series of  WebCenter services provided out-of-the-box within applications. This chapter presents a simple and clear way of how to include RSS feeds, search capabilities, tagging and discussions using practical samples that are easy to follow. Chapter 9: Presents an important component of Oracle WebCenter - the composer. Through the composer and Oracle Metadata Services the composer adds all the functionality to perform end-user personalizations, which is a very common user case when working with portals. The concept is self-explanatory when running over the practice developed in this chapter. Chapter 10: Provides an introduction to WebCenter spaces, explaining common concepts about installation, administration (role creation, group creation, etc) and through a sample, the readers can put everything in practice on their own environments. Summary: This book would provide the reader with a fast start to work with Oracle WebCenter 11g  and its different components. In my opinion the book targets the developer audience, rather than the Portal type of audience, or content generator. For the readers of this book I recommend that to better understand the concepts discussed, first you need to understand the basics on Oracle Application Development Framework. Believe me you can thank me later!

• Why learn Flash Builder 4 (Flex) when I can just use Flash Professional?

  - by Jason McKenna

  I want to learn Flash Builder 4 (Flex) because I see so many jobs requesting experience with it. I also just like knowing stuff. I am also very interested in focusing on RIA development now. BUT... can anyone tell me CLEARLY why the heck I would ever use FLEX over Flash Pro? It is a time investment, so is it worth it? All I read are misguided posts about how Flash Pro is for games and banner ads, and Flex is for programmers and RIAs blah blah... this simply isn't so from my 9 years of contracting experience. I'm 99.9% certain that I can build anything a flex developer can build, but using Flash Pro. I can build powerful AS3-driven apps for the desktop, mobile device, or browser, and I can link to databases with XML and I can import text files and communicate with ColdFusion and everything. The advantage with Flash Pro is that I can also easily and clearly animate transitions and build custom elements that look the way I want/need them to look for my specific client. Why would I want to use a bunch of pre-built components that drive my file sizes to the moon? Who is happy with a drag-n-drop button? Is Flex just a thing made for programmer people with no artistic inclination? What is the advantage of using it? It takes me back to Visual Basic class. Seems like a pain to have to use multiple tools to import crap from Flash Pro into Flex and yada yada... why when I can do it all nicely in Flash Pro to begin with. Am I clueless, or missing some major piece of the puzzle? Thanks for any clarity. PS, I couldn't care less about the code editors. It ain't that bad people. They make it out like the thing doesn't even respond to keyboard input or something. Does everything I need it do anyways. Please help out here. If I just don't need to learn it, I don't want to waste the time.

• Repository/Updating/Upgrading Issue

  - by Jakob

  The other day I was asked to upgrade from 13.04 to 13.10, at the time I was busy and hit no. I can not upgrade/update at this point, I get (error -11) or a 404 in terminal. In the software updater I get 'failed to download repository information.' I have tried changing my "Download From" setting to "Best" to "Main" and even a few other countries. And in "Other Software" I have tried disabling packages, but doesn't seem to help what so ever. I have tried several of the other commands to try and fix it, such as -fix missing or sudo apt-get update clean. P.S. This has also affected my thunderbird client, I cannot send/receive emails. Here is my error log when trying to upgrade: jakob@Skeletor:~$ sudo update-manager -d gpg: /tmp/tmpvejqvl/trustdb.gpg: trustdb created gpg: /tmp/tmpnayby6/trustdb.gpg: trustdb created Traceback (most recent call last): File "/usr/lib/python3/dist-packages/defer/__init__.py", line 483, in _inline_callbacks result = gen.throw(excep) File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 86, in commit True, close_on_done) File "/usr/lib/python3/dist-packages/defer/__init__.py", line 483, in _inline_callbacks result = gen.throw(excep) File "/usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py", line 158, in _run_in_dialog yield trans.run() aptdaemon.errors.TransactionFailed: Transaction failed: Package does not exist Package linux-headers-3.8.0-33 isn't available gpg: /tmp/tmp3kw_hl/trustdb.gpg: trustdb created. And let me throw in my sudo apt-get update too. Which this has been working variably too, but I don't know what to change my repositories to, and disabling does not effect: E: Some index files failed to download. They have been ignored, or old ones used instead. This is the short version, but looks exactly like this fairly consistently. Sometimes it downloads, sometimes it doesn't. Sometimes it tells me I have an update, and doesn't do anything. If it helps, I have recently had issues trying to install Samba as well, and connecting to the office's NAS Drive. Which works now, but I had to edit /etc/fstab/ and a few other things trying to get that to work as well. I understand it could also be a DNS problem, but this has been going on for a few days, as well as I've already tried changing my DNS server via my computer, however I am not allowed to alter the DNS on our company's router.

• Script For Detecting Availability of XMLHttp in Internet Explorer

  - by Duncan Mills

  Having the XMLHttpRequest API available is key to any ADF Faces Rich Client application. Unfortunately, it is possible for users to switch off this option in Internet Explorer as a Security setting. Without XMLHttpRequest available, your ADF Faces application will simply not work correctly, but rather than giving the user a bad user experience wouldn't it be nicer to tell them that they need to make some changes in order to use the application?  Thanks to Blake Sullivan in the ADF Faces team we now have a little script that can do just this. The script is available from https://samplecode.oracle.com here - The attached file browserCheck.js is what you'll need to add to your project.The best way to use this script is to make changes to whatever template you are using for the entry points to your application. If you're not currently using template then you'll have to make the same change in each of your JSPX pages. Save the browserCheck.js file into a /js/ directory under your HTML root within your UI project (e.g. ViewController)In the template or page, select the <af:document> object in the Structure window. From the right mouse (context) menu choose Facet and select the metaContainer facet.Switch to the source code view and locate the metaContainer facet. Then insert the following lines (I've included the facet tag for clarity but you'll already have that):      <f:facet name="metaContainer">        <af:resource type="javascript"                      source="/js/browserCheck.js"/>        <af:resource type="javascript">           xmlhttpNativeCheck(                     "help/howToConfigureYourBrowser.html");        </af:resource>      </f:facet>Note that the argument to the xmlhttpNativeCheck function is a page that you want to show to the user if they need to change their browser configuration. So build this page in the appropriate place as well. You can also just call the function without any arguments e.g. xmlhttpNativeCheck(); in which case it will pop up default instructions for the user to follow, but not redirect to any other page.

• Proxy settings do not promulgate to fat or thin clients

  - by solizin47

  I work in Hertfordshire schools, which use a proxy eg http://wf1.thegrid.org.uk on port 80 to allow graded access by all users, within the schools, to the Internet. I have Ubuntu 10.04LTS successfully running and I want to set up 12.04LTS to replace it. Many other replies to this question have answered questions about stand-alone computers and not addressed the LTSP server and its clients. I have come to a complete stop over the problem of the proxy server settings not promulgating over the local network to Ubuntu 12.04 thin or fat clients. When you input this setting (there are others for HTTPS and FTP) into the System Settings/Network Manager GUI on the server, then when a user logs into the server, both Firefox and Chrome can read the settings and will gain access to the Internet. HOWEVER, these settings are not promulgated to either thin or fat clients on the local network. Their System Settings/Network Manager GUI remains stubbornly blank. I have rebuilt the image after inputting the proxy settings, but it appears they are not part of the image. /etc/environment (on the server) already has: PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" http_proxy="http://wf1.thegrid.org.uk:80/" https_proxy="https://wf1.thegrid.org.uk:80/" ftp_proxy="ftp://proxy.intra.thegrid.org.uk:3128/" I have also tried this export http_proxy="http://wf1.thegrid.org.uk:80" export https_proxy="http://wf1.thegrid.org.uk:80" export ftp_proxy="http://proxy.intra.thegrid.org.uk:3128" within /etc/environment, and that had no effect, either. etc/apt/apt.conf also has: Acquire::http::proxy "http://wf1.thegrid.org.uk:80/"; Acquire::https::proxy "https://wf1.thegrid.org.uk:80/"; Acquire::ftp::proxy "ftp://proxy.intra.thegrid.org.uk:3128/"; The clients still have no proxy settings in their Network Manager, and no client user can access the Internet from Firefox or Chrome. Three questions: Why doesn't the “Apply system wide” button work? It does on 10.04, and every new user, and all existing users have access to the internet through the proxy without problem. How can I set up proxy settings that work for all the 12.04 clients? I noticed that if user West input the settings himself, they would follow him around the clients. However, this is not secure, because there are grades of settings which prevent visits to various sites, eg wf3 allows fewer sites than wf2 or wf1, so I can't allow users to input this setting themselves. Since the proxy setting followed the user around the clients, the setting must be somewhere in the user profile, since none of the other users have the proxy settings. Do you know where, and how I could fix the setting for users, or better, groups? The setting must then be unchangeable by the user, with no access to the Network Manager. If either 2. or 3. can't be done, then the Ubuntu 12.04LTS server is simply no use to us...

• Advantages and disadvantages of building a single page web application

  - by ryanzec

  I'm nearing the end of a prototyping/proof of concept phase for a side project I'm working on, and trying to decide on some larger scale application design decisions. The app is a project management system tailored more towards the agile development process. One of the decisions I need to make is whether or not to go with a traditional multi-page application or a single page application. Currently my prototype is a traditional multi-page setup, however I have been looking at backbone.js to clean up and apply some structure to my Javascript (jQuery) code. It seems like while backbone.js can be used in multi-page applications, it shines more with single page applications. I am trying to come up with a list of advantages and disadvantages of using a single page application design approach. So far I have: Advantages All data has to be available via some sort of API - this is a big advantage for my use case as I want to have an API to my application anyway. Right now about 60-70% of my calls to get/update data are done through a REST API. Doing a single page application will allow me to better test my REST API since the application itself will use it. It also means that as the application grows, the API itself will grow since that is what the application uses; no need to maintain the API as an add-on to the application. More responsive application - since all data loaded after the initial page is kept to a minimum and transmitted in a compact format (like JSON), data requests should generally be faster, and the server will do slightly less processing. Disadvantages Duplication of code - for example, model code. I am going to have to create models both on the server side (PHP in this case) and the client side in Javascript. Business logic in Javascript - I can't give any concrete examples on why this would be bad but it just doesn't feel right to me having business logic in Javascript that anyone can read. Javascript memory leaks - since the page never reloads, Javascript memory leaks can happen, and I would not even know where to begin to debug them. There are also other things that are kind of double edged swords. For example, with single page applications, the data processed for each request can be a lot less since the application will be asking for the minimum data it needs for the particular request, however it also means that there could be a lot more small request to the server. I'm not sure if that is a good or bad thing. What are some of the advantages and disadvantages of single page web applications that I should keep in mind when deciding which way I should go for my project?

• How do I set up nvidia graphics adapter to put out 1080p, it seems to be using interlace mode>

  - by keepitsimpleengineer

  After upgrading to 12.04, my mythbuntu client/server seems to be running in 1080i, the clue comes from: [ 1176.117] (II) NVIDIA(0): Setting mode "1920x1080_60i" [ 1231.340] (II) NVIDIA(0): Setting mode "DFP-1:1920x1080_60@1920x1080+0+0" This is from Xorg.0.log. This whole thing started from video tearing when watching Mythtv recordings. It didn't happen in 10.10. Should I use "TVStandard" "HD1080p" in the screen section since this is a dedicated HTPC?

• How to get my IR remote to work? Lirc can't see it

  I'm using Ubuntu 11.10 (amd64) and I'm trying to get my infrared remote control working. The IR device is a part of a DVB-T USB stick (Based on a RTL2832u chip). I'm using these drivers - it's the only way of getting this device to work under 11.10 that I found. It's a big impromevent from previous Ubuntu version, where I had to edit the driver's code. The device works quite great - and the IR part of it works, too. The driver's page says that the code it's in alpha stage, but I'm pretty sure that my issue has nothing to do with that. If, and only if driver's module is loaded with parameter rtl2832u_rc_mode=2 (which means "use NEC protocol for IR") the remote kind of works, I can see this by running cat /dev/.. ../input6 - when I press a button, random letters appear. The remote works just like a keyboard, but keys are totally messed up - when I press '5' the volume goes down, etc. I would like to use Lirc to fix that, but Lirc can't detect my device (i.e. irw shows nothing). I suspect, it's because something gets into control of the device and sets it up as a keyboard. Lirc seems to be working, it's KDE settings module works too, but it just doesn't detect the device. The Lirc page describes this issue, but since 2009 - the last year when that page was updated, Ubuntu moved from HAL (described there) to DeviceKit, rendering provided instruction useless. I had a similar issue with my previous remote, but the keys were not messed up so much - the remote was usable, so I gave up trying to get Lirc working. I tried the answer provided here, but it changed nothing. I also tried forcing lircd to use my device, but this didn't work too: for i in /sys/class/input/input* ; do echo -n "$(basename "$i"): "; cat "$i/name"; done shows input0: Power Button input1: Power Button input2: Logitech Logitech USB Keyboard input3: A4Tech PS/2+USB Mouse input6: IR-receiver inside an USB DVB receiver But when I run: lircd -n --device=name='IR*' as root (also tried with the full name) I always see: lircd-0.9.0[3983]: lircd(default) ready, using /var/run/lirc/lircd lircd-0.9.0[3983]: accepted new client on /var/run/lirc/lircd lircd-0.9.0[3983]: could not get file information for name=IR* lircd-0.9.0[3983]: default_init(): No such file or directory lircd-0.9.0[3983]: Failed to initialize hardware So, how to set up Lirc with devinput driver in such case?
