• Upcoming Enhancements in AngularJS Integration in NetBeans IDE

  - by Geertjan

  New bleeding edge enhancements in AngularJS support in NetBeans IDE enable many more controllers to be found than in NetBeans IDE 7.4. The next version of NetBeans IDE parses all JavaScript files and checks for defined AngularJS controllers, such as the below: All recognized AngularJS controllers are offered in code completion, as shown below. In other words, code completion works better in finding AngularJS controllers. Another improvement is in the "Go To Declaration" feature. When you click Ctrl+Mouse over the name of a controller inside an NG-controller directive, you will be navigated to the related controller declaration. More accurate results can be shown in code completion mainly because there are changes in the generation of JavaScript virtual sources in an AngularJS page.

• Upgrade from 10.10 to 11:04 to 11.10. X starts, Unity desktop not there

  - by Stefan Lasiewski

  I upgraded my Ubuntu Desktop 10.10 system to 11.04 and then 11.10. Now, when I start Ubuntu, the Unity desktop doesn't start correctly. Here's what I do: Start computer I log in via the GUI login screen The X Window System starts. I can see an arrow icon for the mouse, and can move it around the screen. Nothing else starts. There are no desktop icons, no launcher, no taskbar, etc. Right clicking on desktop does nothing. I've tried some common keyboard shortcuts ("Alt-tab" "Ctrl-Alt-T" "Ctrl-Alt-Backspace") but nothing happens. If I go to another Virtual Console, and run the command unity, the Unity desktop will start on my primary X desktop. However I'm seeing many problems like windows which are only half-drawn, some applications run without the familiar "Minimize, Maximize, Close" What's happening here? It seems that the X Window System started, but Unity did not start? How can I debug this?

• Destroy guest OS using php

  - by Alee

  I am using libvirt-php to manage my virtual machines, and I need to shutdown/destroy domU. For this I used the following php script: < ? php $conn=libvirt_connect("xen:///"); $name=libvirt_domain_lookup_by_id($conn,4); $dest=libvirt_domain_destroy($name); echo $dest; ? When I run this on xampp server i get the following output: Warning: libvirt_domain_destroy() [function.libvirt-domain-destroy]: operation virDomainDestroy forbidden for read only access in /opt/lampp/htdocs/xampp/byname.php on line 5.

• Ubuntu user credentials, file permissions

  - by user9843

  I am using Ubuntu 10.10 for web development by using the symfony framework. Normally I install Ubuntu Lamp (Turnkey edition), log in as root and configure all the necessary software in the server needed to work with symfony. (Samba, symfony etc) The problem is when I am root the file permissions are not set right for the Samba and symfony systems. All things I do/create in the terminal (CLI) of Ubuntu create file permissions for the user root. Off course I know how to change them afterwards but that takes up time I could spend programming. When ready I am using the box via my network, creating several site directorys directly from my pc on the server. There are multiple sites on this developer server as directorys under /var/www/ there are no virtual hosts. My question is how to create or set a user after installation of Ubuntu with the right credentials and rights?

• Licensing Theme Music from other games

  - by HS01

  As part of my game, I thought it would be fun to make a hidden level that pays tribute to Mario Bros (one of the earliest games I ever played). It would be themed in that way with 8-bit graphics and question mark blocks and completing the level would say "Thank you but the princess is in another castle" or such. For the sound track, I'm thinking of just overlaying the standard mario theme music by playing it on a virtual keyboard using a different instrument/timing or something. My question is, am I legally safe? I'm not using anyone else's actual music, I'm just playing the same tune in a different way myself. Do I have to get licensing for this?

• Logic in Entity Components Systems

  - by aaron

  I'm making a game that uses an Entity/Component architecture basically a port of Artemis's framework to c++,the problem arises when I try to make a PlayerControllerComponent, my original idea was this. class PlayerControllerComponent: Component { public: virtual void update() = 0; }; class FpsPlayerControllerComponent: PlayerControllerComponent { public: void update() { //handle input } }; and have a system that updates PlayerControllerComponents, but I found out that the artemis framework does not look at sub-classes the way I thought it would. So all in all my question here is should I make the framework aware of subclasses or should I add a new Component like object that is used for logic.

• When to decide to introduce interfaces (pure abstract base classes) in C++?

  - by Honza Brabec

  Assume that you are developing a functionality and are 90% sure that the implementation class will stay alone. If I was in this position in Java I would probably not use the interface right now to keep the things simple. In Java it is easy to refactor the code and extract the interface later. In C++ the refactoring is not always so easy. It may require replacing values with smart pointers (because of the introduction of polymorphism) and other non-trivial tasks. On the other hand I don't much like the idea of introducing virtual calls when I am 90% sure they won't be needed. After all speed is one of the reasons to prefer C++ over simpler languages.

• How do I get write access to ubuntu files from Windows?

  - by Steven

  I'm running Ubuntu 11.10 on my Virtual Machine as a web server. I've mounted the W:/ drive in Win 7 to my /www folder in Ubuntu. I can read the files, but I'm not able to write to the files. In Samba, I have created the following user: <www-data> = "<www-data>" And given guest ok for the www folder: [www] comment = Ubuntu WWW area path = /var/www browsable = yes guest ok = yes read only = no create mask = 0755 ;directory mask = 0775 force user = www-data force group = www-data I've also run sudo chmod -R 755 www to make ensure correct rw access. What am I missing in order to get write access to my ubuntu files from Windows?

• Windows 2008 R2, UDDI 3.0 and No Admin Links

  - by Andy Morrison

  Windows 2008 R2 might end up giving me a heart attack at some point. Yesterday I installed and configured UDDI 3.0 as part of an ESB 2.0 install & config.  After configuring UDDI 3.0, if I browsed to the localhost/uddi virtual directory from IIS, all of the links would show up in UDDI.  If opened up IE and went to the UDDI site only the Home and Search links would show up. You've probably already guessed at what the "fix" was... I had to Run IE as Administrator.  Then when I browse to the UDDI site all of the links show up.

• Xubuntu 14.04 black screen after monitor off/on

  - by Sampo Smolander

  I have a HP desktop machine with Ubuntu 14.04, with also Xubuntu and Gnome desktops installed. I mostly use the Xubuntu session. When using the Xubuntu session, when I power off my monitor, and power it back on, the screen stays black and I cannot do any work. With ctrl-alt-f6 I can open another virtual terminal, and then the screen works again, but if I to go back to the desktop session with ctrl-alt-f7, all I have is a black screen. But, if I login to Unity (the Ubuntu default session), or to Gnome, and turn the monitor off and back on, everything works ok. Also, if I log out, and while in the lightdm greeter, turn the monitor off and back on, everything works ok. What could be the cause for this, and how to fix this?

• 4 Places To Find Up-To-Date Antivirus Test Results Online

  - by Chris Hoffman

  Do you know how effective your antivirus programs is? A variety of organizations regularly compare antivirus programs, throwing a large amount of malware samples at them, seeing how they perform, and ranking them in comparison to each other. It would be very time-consuming to test 30 different antivirus programs in virtual machines with a large amount of malware samples yourself, which is why these test results are so useful.

• How should I select continuous integration tool?

  - by DeveloperDon

  I found this cool comparison table for integration servers on Wikipedia, but I am a little uncertain how to rank the tools vs. my needs and interests. The chart itself seems to have a lot of boxes marked unknown, so if you are comfortable updating it on Wikipedia, that could be great too. Are there a few top performing products so I can quickly narrow down to four or five options? Which products seems to have the largest user communities and most ongoing enhancements and integration with new tools? Are the open source offerings best, or are there high quality tools that can be a great deal for a single user at home? Will use of multiple systems (primary desktop, local only home network server, personal and work notebooks, multiple virtual machines spread across all) create problems and how can they be managed?

• How to link subprograms to a main program's game loop?

  - by Jim

  I recently discovered Crobot which is (briefly) a game where each player codes a virtual robot in a pseudo-C language. Each robot is then put in an arena where it fights against other robots. A robots' source code has this shape : /* Beginning file robot.r */ main() { while (1) { /* Do whatever you want */ ... move(); ... fire(); } } /* End file robot.r */ You can see that : The code is totally independent from any library/include Some predefined functions are available (move, fire, etc…) The program has its own game loop, and consequently is not called every frame My question is roughly : how does it work ? It seems that each robot's code is compiled by the main program and then used in a way I cannot understand. I thought it could yields a thread for each robot, but I have not any proof of this and it seems a bit complicated to achieve it. Any idea how it could work, someone ?

• What's the correct MAAS DHCP configuration?

  - by k to the z

  I've set up a MAAS controller by following this documentation: http://maas.ubuntu.com/docs1.4/cluster-configuration.html However, when I got to the DHCP configurations I was a little puzzled. The controller I created is at 172.16.142.61. It looks like that's the address for the "IP" text field. Going down the rest of the list I'm unsure of though. Should I just put in the subnet/broadcast/router (is that the gateway?) that the MAAS server resides in or am I suppost to just list the static address of the MAAS server and then define my own "virtual" subnet in the fields below?

• SOA Suite 11g: Unable to start domain (Error occurred during initialization of VM)

  - by Chris Tomkins

  If you have recently installed SOA Suite, created a domain and then tried to start it only to find it fails with the error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. the solution is to edit the file <domain home>\bin\setSOADomainEnv.cmd/sh (depending on your platform) and modify the line: set DEFAULT_MEM_ARGS=-Xms512m -Xmx1024m to something like: set DEFAULT_MEM_ARGS=-Xms512m -Xmx768m Save the file and then try to start your domain again. Everything should now work at least it does on the Dell Latitude 630 laptop with 4Gb RAM that I have. Technorati Tags: soa suite,11g,java,troubleshooting,problems,domain

• Turn based battle and formula

  - by Mark Chapman

  I'm building a game called DVP(Digimon Virtual Pet), and in this game other than taking care of your digimon, You can also battle and breed them. I'm working on the battle system (making it first cause the actual pet system will be easy compared to the netplay, or 39DLL)but here is the problem I don't want it to be "too" simple or "too" complicated, but I do want to go by a certain formula. There are str, def, spd, and int. Strength: How hard the attacking digimon is hitting Defense: How much damage your digimon can defend when being attacked Speed: The chance of you missing the enemy Intelligence (battle knowledge): The chance of you hitting a critical hit or defending a critical hit. I can make a super simple turn based example, but I don't know how exactly to make the formulas for what I've explained above, any help?

• Intermittent Copy/Paste Problem in RDP

  - by Tara Kizer

  If you use RDP to remotely connect to your servers, you've probably encountered a clipboard issue where copy/paste stops working.  A quick Google search on the problem indicates you can easily fix the problem by logging out/logging back in or killing/restarting rdpclip.exe on the remote server.  Here's an article which covers this topic. But what do you do when copy/paste is intermittent?  It works one second, stops working for 5-30 seconds, and then on its own starts working again.  This is what’s occurring in our new non-production environment.  The DBA team is setting up 16 new physical servers and 5 new virtual machines.  I haven’t found a server where this ISN’T happening.  This intermittent copy/paste issue is driving me crazy!

• How to set up bridged networking in Xen?

  - by Joe Carr

  I have 2 domU virtual machines installed on a 11.10 Oneiric Dom0. My internal network is on the 192.168.1 subnet, and when the domU's start, they get ips on the 192.168.122 subnet. I have attempted to follow the instructions here : http://wiki.kartbuilding.net/index.php/Xen_Networking xend-config.sxp is configured correctly, but neither of my domU's have a config file in /etc/xen to modify. ifconfig reports that I have the following devices : eth0, lo, tap3.0, vif3.0, vif4.0, virbr0 bridge-utils is installed. I also just attempted to follow these steps : http://serverfault.com/questions/233201/bringing-the-xenbr0-interface-up-on-xen-under-ubuntu-8-04 sudo brctl addbr xenbr0 sudo brctl addif xenbr0 vif3.0 device vif3.0 is already a member of a bridge; can't enslave it to bridge xenbr0. Any ideas on next steps are greatly appreciated!

• Multiple Monitors using nvidia-prime or bumblebee on Ubuntu 13.10

  - by user205626

  I've been unable to get multiple monitors to work with Ubuntu 13.10 using nvidia-prime or bumblebee. Could someone point me in the right direction? With nvidia-prime, I've tried the xorg.conf here http://us.download.nvidia.com/XFree86/Linux-x86/319.12/README/randr14.html, but I boot into "low graphics" mode and have to revert to get a desktop back. Any suggestions would be appreciated. Thanks. Edit: I've given up on nvidia-prime; I missed the fact that it never turns off the discrete card... So, I'm back to trying to get VIRTUAL displays working with Bumblebee.
