• Quatre nouveaux Google Web Elements pour aider la création de Wikis ou de magasin en ligne, et le re

  Quatre nouveaux Google Web Elements Personnalisables par les développeurs Webs et le retour de Google Wave Google propose quatre nouveaux outils d'aide à la création de sites. Ils complètent son offre Google Web Elements. Si ces outils clefs en main sont à la base ciblent les débutants, ils sont également destinés aux développeurs. « Les Web Elements sont un excellent point de départ, car ils s'appuient sur des APIs qui vous donnent plus de contrôle sur le contenu ou la présentation », précise l'équipe du projet. La première de ces APIs, et certainement la plus intéressante, permet d'intégrer et d'adapter un Wiki à un site pré-existant Logiquement baptisé Side...

• GlassFish Community Event @ JavaOne - Save the date!

  - by alexismp

  The interest for having a GlassFish community event at JavaOne is still very strong both inside Oracle and in the community, so this year again we'll be hosting a get together on the Sunday prior to the main event. If you're in town and attending JavaOne, mark your calendars : Sunday 2nd, October 2011 - 12:30pm-4:30pm in the Moscone This will be an opportunity to discuss the community status (adoption of Java EE 6, GlassFish 3.1.x) and hear about future plans, mainly around Java EE 7 and the related GlassFish release(s). We'd also like to have several participants share their deployment stories as well as some time for an free-form unconference format and some team building activity. Of course, beyond all the content shared in slides, this should really also be a good excuse to meet folks from the community and from the core GlassFish team at Oracle. Here's a post on last year's event. And before anybody asks, we are still exploring the party situation :-)

• Good places for starting to learn Lua scripting [closed]

  - by Cascalho

  I want to start learning to script in lua for game development. I could start with the official Lua tutorials, but I would rather study scripts that were written specifically for games and learn the syntax from there as I believe this is faster and more related to what I want. Can you recommend tutorials in video or text that are very detailed in explaining the code? Or some open source game with heavily commented code? What I want is something detailed that walks me through it, so I start understanding both the syntax and how each piece relate to each other, like "First of all, install this, this and that." "So, here we are defining a new function that will make the player jump." "This is the main script that calls the other ones. It defines these variables." "This function tests if the player is alive."

• Keeping application backend and UI synchronised

  - by Deanna

  Hi all. I have an app that works with a list of objects so has one central keyed list. The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading. Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit. I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way. I can also do it lazily and repopulate the tree each time or periodically (very hackish). Does anyone have any better thoughts on how to structure this? This is being done in C# 2.0 but the concepts apply to any environment. Thanks

• Good way of handling class instances in game development?

  - by Bugster

  I'm a new indie game developer, and I've made a few games, but often times when coding I wonder "Is this the way most people do it? Am I doing it wrong?" because I'd like to become a game developer some day, and I really want to get rid of bad practices in time. The way I'm doing it right now is like this: #include <some libraries> #include "Some classes" int main() { Class1 a; Class2 b; Class3 c; a.init(); b.init(); c.init(); // game logic; } Now as I see the game grow, I have more and more classes to initialize and create instances of. This is clean but I'm not sure if this is standard practice. Is this a regular way of creating instances of your game classes or is there a cleaner and more efficient way to do it?

  - by cj333

  We have a site. our main servers is for blogs and freedom write. Our custom can submit their article in our site. But for ptotect the copywrite, we do not allow custom just do easy copy and parse a whole article from other site. At least they should write something by themselves.

  - by user254074

  Maybe I am missing something but all I want to do is be able to access and transfer files from one folder on my main computer to my htpc. Both computers are running Ubuntu 14.04.

I went into nautilus then Browse Network Windows Network Workgroup but I get an error and it won't let me access it. Is there something I am doing wrong?

• Why don't my Google Analytics custom segmentation visit numbers match up?

  - by Hates_

  I have three main areas of my site and want to track total usage as well as breakdowns of the three parts. I am trying to segment the "type" of use on each page using a custom variable as such: ['_setCustomVar',1,'Visitor Type','Unknown',1] Visitor type can be one of three values: "Unknown", "Reader" or "publisher". Every page has this value set. Now when I look at my analytics chart and chose all three segments, the individual values do not match the sum. I've double checked the pages to make sure the custom var is there.

• Ubuntu 12.04 x64 - Very slow response and sluggishness

  - by Murphy1138

  Recently updated to 12.04 x64 on my AMD HEX core 4GB system, over the last few days I feel that the overall system is sluggish/laggy , for instance hitting the dash button, the dash opens but the recent activity of files/videos etc is incredibly slow to populate, like wise in Nautilus and browsing my media, the file names are showing up but it takes an age to populate the "thumb" of the video, If I go into Gnome-shell the shell response is a little faster but again clicking on applications there is still a noticeable pause. I have the latest Nvidia Drivers loaded and I have very fast SATA drives, if I reboot into windows 7 the system is so much quicker in its response, I only use windows for games and Ubuntu is my main OS. 10.04/10.10/11.04 was Super quick and this was when the system still had a Duel Core Chip and a worse Nvidia card, 11.10 was pretty snappy, but 12.04 just feels bloated on each system I have installed it on. My hardware is more than up to the task so has anyone got any commands i can run to help diagnose the issue? Anyone else got the same problems? Thanks Murph

• .htaccess mobile redirect issues

  - by val

  I'm trying to set up a mobile redirect for a site with 2 subfolders, and I cannot get both to work at the same time. This is the structure of the site www.mysite.com/EN/ www.mysite.com/ES/ This is a bilingual site so each subfolder contains the files corresponding to each language version. Then I was using a 301 redirect, and setting up the index in /EN/ as the main index. Everything was getting redirected to it. I was using DirectoryIndex index.html Redirect /index.html http://www.mysite.com/EN/index.html and several Rewritecond to redirect mysite.com and old urls to the new URL. It worked fine before I decided to add a mobile version - m.mysite.com. I used the solution provided in http://stackoverflow.com/questions/3680463/mobile-redirect-using-htaccess, and it redirects my mobile version properly, but now the desktop is both working. Besides, my mobile version must be bilingual as well.

• Monitor screen size and programming ease

  - by rrazd

  I recently heard that a big part in successful/quick debugging and easing the process of programming is to use a big screen. I may be purchasing a new computer in the future and this has me wondering: 1)Is the aforementioned statement actually true or is it a bit of a stretch? 2)Have you noticed that this plays a significant enough part to buy a bigger screen if the bigger screen is significantly more expensive? 3)Is it common for developers to work on 13'' laptop screen as their main (and only) workstation (this is what I currently develop on) or is this actually disadvantageous? This may be subjective but any professional opinions/experiences would be greatly appreciated!

• Desktop in Kubuntu lacks bars and quite everything after trying to apply Plymouth fix for proprietary drivers

  - by Michcioperz

  I'm running Kubuntu 13.10, my computer's graphics card is Nvidia GT 520. I tried to fix that Plymouth's problem with proprietary graphics driver using an old script I found on the internet (it was coded for Natty, now that I think about it I shouldn't have done it). I ran that script and rebooted my computer. First incorrect behaviour I noticed was that Plymouth only displayed its text splash only on 1/4th of the screen, though when I pressed Esc key the logs were displaying correctly. Main problem appeared when I logged in. All my desktop's windows lack menu bar, can't be closed with Alt-F4, and they don't appear on the task bar. I tried fixing it by reinstalling GRUB a few times, purging /etc/grub.d and /boot/grub, but only the text splash issue was fixed. How can I fix that?

• Reliable method for google analytics tracking for print advertising campaign?

  - by chrisjlee

  A client is looking to track advertising clicks through a newspaper ad to measure success. They have rigid business requirements that it will be a unique domain... e.g. foowidgetsnews.net instead of foodwidgets.com/contact-form-page.php What is the most reliable method of building redirected url to a landing page so it will be tracked in google analytics as a direct hit from the newspaper? Finally, we would like to track the foowidgetsnews.net as the main url in google analytics because 301 redirect isn't tracked in google analytics like the way we would like it to.

• What to use for an event listing site? [on hold]

  - by Vykintas

  I have a site which lets users buy & sell tickets, but it's built on wordpress & buddypress. So it's very heavy and messy. I would like to re-do the whole site on something lighter, cleaner and solid. The main functionality for user would have to be as follows: Register or login via Facebook. Create events and sell tickets to them. See ticket sales statistics Upload photos and associate those with events. Buy event tickets, print pdf ticket. Comment, favourite and like events. What would be your suggestions? PHP framework? CMS? CMF? I must say that I'm a front-end dev so building a system from scratch on my own would take a while. I'd be interested more in a "skeleton" app solution or something similar.

• Code for Controlling the Bike in a bike game

  - by user1489257

  I'm new(ish) to Actionscript 3 and I was wondering what the code what would be like for controlling the bike in a game. I have a two main questions: Is Box2D the best physics engine to go with for this type of game? How would the animation of the bike work. Would I have to create a bike animation of the wheels moving and make it start and stop when the key to go forward is pressed. How would I go about it slowly stopping when the key to go forward is released? Thanks.

  - by user285982

  I am using Ubuntu 10.10 64 bit, and I can browse the internet fine. I am typing this using the machine.

• What would you choose for your project between .NET and Java at this point in time ?

  - by Basic

  You are just starting a new project and you have these two technologies to choose from, Java and .NET. The project you are working doesn't involve having features that would make it easy to choose between the two technologies (e.g. .NET has this that I need and Java does not) and both of them should work just fine for you (though you only need one of course). Take into account: Performance Tools available (even 3rd party tools) Cross platform compatibility Libraries (especially 3rd party libraries) Cost (Oracle seems to try and monetize Java) Development process (Easiest/Fastest) Also keep in mind that Linux is not your main platform but you would like to port your project to Linux/MacOs as well. You should definitely keep in mind the trouble that has been revolving around Oracle and the Java community and the limitations of Mono and Java as well. It would be much appreciated if people with experience in both can give an overview and their own subjective view about which they would choose and why.

• Implementing unlockable items on Android

  - by coder_For_Life22

  I know this would be a beginners question (some of you might think) but I would like to know different approaches for this. I have a game with lets say 20 unlockable items, at the main menu I have a button where the user can go to an activity and view the unlockable items. So I would like for it to have a "Locked image" and under it a text telling you what the item is and maybe how to unlock it. What is the best way of going about this? And then when the item is unlocked during the game, maybe put a variable in the shared preference and check at the beginning of the activity with the unlockabled items. Let me know what you guys think. Thanks.

• Sound Delay With AVAudio Player

  - by Will Youmans

  I'm using the following code in my viewDidLoad to load a sound: NSURL * url = [NSURL fileURLWithPath: [NSString stringWithFormat:@"%@/Moto - Hit Sound.mp3", [[NSBundle mainBundle] resourcePath]]]; NSError * error; hitSoundPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:url error:&error]; hitSoundPlayer.numberOfLoops = 0; Then I'm using this in a void method to play the sound: if(CGRectIntersectsRect(main.frame, enemy1.frame)){ [hitSoundPlayer play]; } This does seem to work, however the first time the sound is played there is a lot of lag and the game stops temporarily. I'm using this same method for when in an IBAction and it works fine, it must be the fact that it's also detecting a collision that makes the sound lag. If I want to be able to play sounds quickly and on the spot without any sort of lag am I doing the right thing? Do I want to use another method? I'm not using any frameworks like cocos2d. If you need to see any more code just ask.
