  • EL 3.0 Public Review - JSR 341 and Java EE 7 Moving Along

    - by arungupta
    Following closely on the lines of EL 3.0 Early Draft, the specification is now available for a Public Review. The JCP2 Process Document defines different stages of the specifications. This review period closes Jul 30, 2012. Some of the main goals of the JSR are to separate ELContext into parsing and evaluation contexts, adding operators like equality, string concatenation, etc, and integration with CDI. The section A.7 of the specification highlights the difference between Early Draft and Public Review. Download the Public Review and and follow the updates at el-spec.java.net. For more information about EL 3.0 (JSR 341), check out the JSR project on java.net. The archives of EG discussion are available at jsr341-experts and you can subscribe to the users@el-spec and other aliases on the Mailing Lists page.

  • AndEngine doesn't fill correctly an image on my device

    - by Guille
    I'm learning about AndEngine a little bit, I'm trying to follow a tutorial but I don't get to fill the background image correctly, so, it's just appear in one side of my screen. My device is a Galaxy Nexus (1270x768 I think...). The image is 800x480. The code is: public EngineOptions onCreateEngineOptions() { camera = new Camera(0, 0, 800, 480); EngineOptions engineOptions = new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new FillResolutionPolicy(), this.camera); engineOptions.getAudioOptions().setNeedsMusic(true).setNeedsSound(true); engineOptions.getRenderOptions().setMultiSampling(true);//.getConfigChooserOptions().setRequestedMultiSampling(true); engineOptions.setWakeLockOptions(WakeLockOptions.SCREEN_ON); return engineOptions; } I have been trying with several values in the camera, but it doesn't fill in all the screen, why?

  • 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).

  • Ars Technica .ars URL suffix -- Vanity or SEO Benefit?

    - by yc01
    The Technology website Ars Technica has adjusted their URL rewrite rules to end with a .ars. Traditionally, sites have taken advantage of this URL rewriting capability to completely eliminate file suffixes like .html, .php, .aspx etc, under the theory that this made for better SEO (since the content of the URL was more relevant to the content) Ars Technicas, though, look like this: http://arstechnica.com/science/news/2011/03/flow-from-the-poles-drive-sunspot-levels.ars So, is Ars Technica adding the .ars file suffix purely a vanity play? Or is it an SEO trick to improve the site's SEO by cleverly inserting their site name into every URL slug? And, if this is indeed an effective SEO trick, should other sites follow suit?

  • Better way to do AI Behavior in AS3/Flixel

    - by joon
    I'm making a game in Flixel and I need to program an NPC. It's rapidly turning more complex than I expected. I was wondering if there are any best practices, tutorials or examples that you can refer me to, to see how this is done. I can probably hack it together, which is what I always do, but it would be nice if I can make it maintanable and can add stuff later on. Here's screenshot to give you an idea: The butler will be an NPC that will follow you, or guide you, and talk to you the whole time. EDIT: More specifically: What I have now is a long list of IF statements in the update loop of the butler (about 8 different cases), and all I have covered is his walking behavior. I want him to comment on things and sometimes switch his main behavior to be more aggresive or distant,... Is there any way to keep track of this, or is complex code with many many nested if statements the way to go?

  • why not use unmanaged safe code in c#

    - by user613326
    There is an option in c# to execute code unchecked. It's generally not advised to do so, as managed code is much safer and it overcomes a lot of problems. However I am wondering, if you're sure your code won't cause errors, and you know how to handle memory then why (if you like fast code) follow the general advice? I am wondering this since I wrote a program for a video camera, which required some extremely fast bitmap manipulation. I made some fast graphical algorithms myself, and they work excellent on the bitmaps using unmanaged code. Now I wonder in general, if you're sure you don't have memory leaks, or risks of crashes, why not use unmanaged code more often ? PS my background: I kinda rolled into this programming world and I work alone (I do so for a few years) and so I hope this software design question isn't that strange. I don't really have other people out there like a teacher to ask such things.

  • Installing netflix, terminal is getting hung up

    - by Twiggins
    Just got Ubuntu up and running, I am attempting to follow the steps laid our here to install Netflix via Wine. I have done the 3 terminal commands, and I believe the package has downloaded. The commands: sudo apt-add-repository ppa:ehoover/compholio sudo apt-get update sudo apt-get install netflix-desktop After this the terminal spits out a user agreement, and I cannot get past this. Is there some way to minimize the window within the terminal? This is what I see: . Netflix is not yet in my dash. It also appears that a variety of other updates are being held up, I assume, because my terminal is midthought.

  • Subclassing to avoid line length

    - by Super User
    The standard line length of code is 80 characters per line. This is accepted and followed by the most of programmers. I working on a state machine of a character and is necessary for me follow this too. I have four classes who pass this limit. I can subclass each class in two more and then avoid the line length limit. class Stand class Walk class Punch class Crouch The new classes would be StandLeft, StandRight and so on. Stand, Walk, Punch and Crouch would be then abstract classes. The question if there is a limit for the long of the hierarchies tree or this is depends of the case.

  • Ubuntu GUI crash when LightDM enters, unable to login

    - by Cesar
    This issue happened spounteniously, i don´t know what could have cause it as i wasn´t using the PC when it happened. I ruled out any messing around with the setting as the user doesn´t know how to enter the BIOS, doesn´t have the sudo password and was only using firefox and libreoffice when it happened. After the plymouth sequence i get this error. https://www.dropbox.com/s/uf1xdkqkw9alvcu/IMAG0252.jpg And this option: https://www.dropbox.com/s/tpivkgjkx2spa3v/IMAG0253.jpg I follow each option and nothing happens after that. The issue persist after rebooting. I choose the other options to see if anything happens, i either get back to option 1 or doesn´t show anything anormal. (I have pictures i someone wants to know) What i found weird is that event though the error is possitioned in the chip, however ubuntu 10.04 and 12.04 run fine in a live CD I saw that some people are having issues when LightDM has a non default wallpaper, but i use a default one. Thanks in advance.

  • HDMI audio output problems with Radeon card

    - by Matt Robinson
    No matter how much advice I follow, I still cannot get any audio to come out through my HDMI connection. I've tried downloading the latest proprietary FGLRX graphics drivers, and I've also gone into /etc/default/grub and altered GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" into this GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" But still I cannot get any sound nor can I get HDMI sound output to show up in Sound Settings or Pulse Audio Volume Control. I can get video to show up just fine on my monitor through HDMI so I'm sure this problem is fixable! I know this is an old problem with Ubuntu, but any new strategies into the problem would be much appreciated. With that being said, here are some of my specs: Ubuntu 12.04 LTS AMD Radeon HD 7520G

  • How to clone a VirtualBox Disk

    - by [email protected]
     How to clone a VirtualBox DiskCopying the image of Virtual Disk (.vdi file) is a convenient way to duplicate the disk, in cases you want to avoid re-installing an operating system from scratch. However, simply copying the .vdi file into another location will make a verbatim copy of the virtual disk, including the UUID of the disk. If you try to add the copy in the Virtual Media Manager, you will get an error like this:In this case, you have to do is to clone the vdi disk: cd C:\Program Files\Sun\VirtualBox\C:\Program Files\Sun\VirtualBox>vboxmanage clonevdi G:\VMWARES\Database\11GR2onOEL5forVbox\11GR2_OEL5_32GB.vdi G:\VMWARES\Database\11GR2onOEL5forVbox\OEL5_32GB.vdi$ VBoxManage clonevdi Master.vdi Clone.vdiIn case you receive a error like this. It means that the disk is already a copy of other VirtualBox Disk.In that case you chould change the UUID before to clone the Disk.Follow the steps given here in order to do that.

  • Good practice about Javascript referencing

    - by AngeloBad
    I am fighting about a web application script optimization. I have an ASP.NET web app that reference jQuery in the master page, and in every child page can reference other library or JavaScript extension. I would like to optimize the application with YUI for .NET. The question is, I should put all the libraries reference in the master page or to compress all the JavaScript code in a single file, or I should create a file for every page that contains only the code useful to the page? Is there any guidance to follow? Thanks!

  • My ubuntu partition was deleted and I can't boot from either a DVD or USB

    - by ropudito
    It's my first time installing ubuntu. I have Windows 7 and 8 before in my laptop (Acer Aspire 4752z). After Ubuntu (12.04) installed in my laptop, the Windows boot loader didn't recognize my Ubuntu so I updated grub from a live USB. And after grub updated, Ubuntu was booting perfectly but my Windows wasn't listed in the grub menu. So I follow someone instruction to update grub again. And after reboot, the grub menu didn't show anymore. After searching about this problem on the net and trying to update grub again and again, I decided to delete the Ubuntu partition from live USB. And shortly after, I booted to Windows with Hiren boot and I used mbrfix. But i think it failed. Now i cant show my BIOS setup or boot from DVD or USB. After that, the only screen i can see after booting is: error: unknown filesystem grub rescue>

  • Acceptable GC frequency for a SlimDX/Windows/.NET game?

    - by Rei Miyasaka
    I understand that the Windows GC is much better than the Xbox/WP7 GC, being that it's generational and multithreaded -- so I don't need to worry quite as much about avoiding memory allocation. SlimDX even has some unavoidable functions that generate some amount of garbage (specifically, MapSubresource creates DataBoxes), yet people don't seem to be too upset about it. I'd like to use some functional paradigms to write my code too, which also means creating objects like closures and monads. I know premature optimization isn't a good thing, but are there rules of thumb or metrics that I can follow to know whether I need to cut down on allocations? Is, say, one gen 0 GC per frame too much? One thing that has me stumped is object promotions. Gen 0 GCs will supposedly finish within a millisecond or two, but if I'm understanding correctly, it's the gen 1 and 2 promotions that start to hurt. I'm not too sure how I can predict/prevent these.

  • What is the difference between Java 6 and PHP 5.4? [closed]

    - by Mashael
    First of all, let me explain the matter. I'm in a class where we learn Java 6 OOP fundamentals. However, my goal is to learn PHP (the last version) next. So, my question: Is there a big difference between PHP and Java 6 in OOP concepts? Meaning that after I finish the OOP class in Java will I find a lot of things that need to be learned in PHP regarding OOP? Update: *My goal of learning PHP next is to build dynamic sites* (I'm not sure of other options) and to follow OOP.

Kevin will be a regular contributor to this blog so stay tuned for more posts from him. When I speak to a room of IT administrators, I like to begin by asking them if they have implemented a complex password policy. Generally, they all nod their heads enthusiastically. I ask them if that password policy requires long passwords. More nodding. I ask if that policy requires upper and lower case letters – faster nodding – numbers – even faster – special characters – enthusiastic nodding all around! I then ask them if their policy also includes a requirement for users to regularly change their passwords. Now we have smiles with the nodding! I ask them if the users have different IDs and passwords on the many systems that they have access to. Of course! I then ask them if, when they walk around the building, they see something like this: Thanks to Jake Ludington for the nice example. Can these administrators be faulted for their policies? Probably not but, in the end, end-users will find a way to get their job done efficiently. Post-It Notes to the rescue! I was visiting a business in New York City one day which was a perfect example of this problem. First I walked up to the security desk and told them where I was headed. They asked me if they should call upstairs to have someone escort me. Is that my call? Is that policy? I said that I knew where I was going, so they let me go. Having the conference room number handy, I wandered around the place in a search of my destination. As I walked around, unescorted, I noticed the post-it note problem in abundance. Had I been so inclined, I could have logged in on almost any machine and into any number of systems. When I reached my intended conference room, I mentioned my post-it note observation to the two gentlemen with whom I was meeting. One of them said, “You mean like this,” and he produced a post it note full of login IDs and passwords from his breast pocket! I gave him kudos for not hanging the list on his monitor. We then talked for the rest of the meeting about the difficulties faced by the employees due to the security policies. These policies, although well-intended, made life very difficult for the end-users. Most users had access to 8 to 12 systems, and the passwords for each expired at a different times. The post-it note solution was understandable. Who could remember even half of them? What could this customer have done differently? I am a fan of using a provisioning system, such as Oracle Identity Manager, to manage all of the target systems. With OIM, and email could be automatically sent to all users when it was time to change their password. The end-users would follow a link to change their password on a web page, and then OIM would propagate that password out to all of the systems that the user had access to, even if the login IDs were different. Another option would be an Enterprise Single-Sign On Solution. With Oracle eSSO, all of a user’s credentials would be stored in a central, encrypted credential store. The end-user would only have to login to their machine each morning and then, as they moved to each new system, Oracle eSSO would supply the credentials. Good-bye post-it notes! 3M may be disappointed, but your end users will thank you. I hear people say that this post-it note problem is not a big deal, because the only people who would see the passwords are fellow employees. Do you really know who is walking around your building? What are the password policies in your business? How do the end-users respond?

    Do you follow any any conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term do you: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? Thanks for any replies.

  • Azure Table Storage Creation using Nov 2009 CTP

    - by kaleidoscope
    The new SDK introduces a new class - · The CloudTableClient : This new class enables us to create tables and test for the existence of tables. We need not need use this class for querying table storage, it's   more of an administrative class for dealing with table storage itself.   · Once we have got the account key and the account name from ConfigurationSetting, we can create an instance of the storage credentials and table client classes:   StorageCredentialsAccountAndKey creds = new StorageCredentialsAccountAndKey(accountName, accountKey);     CloudTableClient tableStorage = new CloudTableClient(tableBaseUri, creds);     CustomerContext ctx = new CustomerContext(tableBaseUri, creds);     //where tableBaseUri is the TableStorageEndpoint obtained from ConfigurationSetting Using the table storage class, we can now create a new table (if it doesn't already exist):     if (tableStorage.CreateTableIfNotExist("Customers"))     {        CustomerRow cust = new CustomerRow("AccountsReceivable", "kevin");         cust.FirstName = "Kevin";        cust.LastName = "Hoffman";        ctx.AddObject("Customers", cust);        ctx.SaveChanges();     } For a complete article on this topic please follow this link: http://dotnetaddict.dotnetdevelopersjournal.com/azure_nov09_tablestorage.htm Tinu, O
