  • Errors happen when using World.destroyBody( Body body )

    - by minami
    on Android application using libgdx, when I use World.destroyBody( Body body ) method, once in a while the application suddenly shuts down. Is there some setting I need to do with body collision or Box2DDebugRenderer before I destroy bodies? Below is the source I use for destroying bodies. private void deleteUnusedObject( ) { for( Iterator<Body> iter = mWorld.getBodies() ; iter.hasNext() ; ){ Body body = iter.next( ) ; if( body.getUserData( ) != null ) { Box2DUserData data = (Box2DUserData) body.getUserData( ) ; if( ! data.getActFlag() ) { if( body != null ) { mWorld.destroyBody( body ) ; } } } } } Thanks

  • Terminal line glitches

    - by foxy
    I installed Ubuntu 11.10 mini + LXDE and wanted to make my command line different in terminal (than just plain white), so I added blue color to path line (everything until $ sign) and it works fine but I have two strange glitches now: When i write a line which is longer than terminal window, instead of starting at next line it starts at the same one, overwriting everything which was in there. Sometimes while navigating over previous commands (up/down arrow keys) some part of command gets stuck and is treated as part of prompt (the blue text), but it is white and is non-deletable and is not taken as part of command when i press enter. What could I mess up? The bad thing is that I don't remember what exactly did I change, but i'm sure I changed only one line in bashrc

  • Strategy for building an application to replace a large spreadsheet

    - by Dan Walmsley
    I'm working on an application that is going to replace a rather large spreadsheet. The spreadsheet is used to budget purchases and things like that. It is the largest spreadsheet I have ever seen, and it required a lot of manual data entry, so this application is going to automate much of that. But as I'm working on this I've noticed its slow going. And I got to thinking this must be a common thing to do many companies will start with something like a spreadsheet, then when they get too big to maintain that, they will get a custom application built. So is there anything out there ( a framework or similar ) that does this sort of thing, migrating a spreadsheet to a custom application. I've had a quick Google but not really seen the kind of thing that I'm looking for. It's too late for this project, but I thought it would be worth having a look for next time. How do you guys tackle this problem?

  • Why was libhal removed in Ubuntu 13.10?

    - by I-Jo
    After installing 13.10, I realized libhal was no longer a sudo apt-get install away... in fact it was no longer anywhere to be found (except in the Raring Repos). And installing libhal from the raring repos is not the best option. It is the best workaround for not having it. Why was it removed? Was it an accidental removal, or is it no longer going to be included in the repos, even in the next LTS? I ask because Amazon (and other services) require it to be installed.

  • On a queue, which end is the "head"?

    - by Aidan Cully
    I had always thought that the "head" of a queue as the next element to be read, and never really questioned that usage. So a linked-list library I wrote, which is used for maintaining queues, codified that terminology: we have a list1_head macro that retrieves the first element; when using this library in a queue, this will be the first element to be removed. But a new developer on the team was used to having queues implemented the other way around. He described a queue as behaving like a dog: you insert at the head, and remove at the tail. This is a clever enough description that I feel like his usage must be more widespread, and I don't have a similarly evocative description of my preferred usage. So, I guess, there are two related questions: 1, what does the "head" of a queue mean to you? and 2, why do we use the word "head" to describe that concept?

  • Interactive training site for Javascript complete with code challenges [closed]

    - by Chase Florell
    A few months ago I discovered a cool course called Rails for Zombies. This is a great site that allows us to write code and see the results. It takes us through the paces to get us up to speed with Rails. You have to pass each level (including code challenges) before being taken to the next level, and it gets you grounded in the fundamentals of Rails. I'm wondering if an interactive tutorial site exists for Javascript? One that will walk me through the paces of writing better Javascript, and challenge me along the way.

  • On github (gist) what is the star-button used for?

    - by user unknown
    On github::gist what is the star-button used for? For example here: https://gist.github.com/1372818 I have 3 Buttons in the headline, they are edit download (un)star With the last one changing from star to unstar. My first idea was: Upvote system. But I can star my own code, and I didn't mention some star appearing somewhere. Next idea: a favorite, a bookmark. I can select 'starred gists' but the page came up even before I starred it. Reading the Help didn't let me find something about 'star', and the searchbox is for searching in code, in pages - not to search the helppages of github::gist.

  • Web Developer Portfolio - Role Definition

    - by GSTAR
    I'm just putting together a portfolio that lists all the websites I have developed / worked on during the past year. Now this has become quite a long list - simply because 60% of the websites I have listed are ones where I have developed certain sections of the site, or maybe re-developed a certain section of an existing site - but not actually developed the whole site. So basically you could say I made a 20-50% contribution on those particular sites. I don't want to give the false impression to a potential employer that I have actually fully developed all the sites listed on my portfolio. Therefore I am after a neat way to indicate this fact. On the websites that I have fully developed, I have put a small label next to the name which reads "Lead Developer". What would be the equivalent label to put on the sites I have partially developed, or projects where I have been amongst multiple people developing? I suppose what I'm asking is, how would you define, in 2-3 words a non-lead developer role within a project?

  • Digikam: What's the problem?

    - by Unapiedra
    I installed Digikam by using the Philip5-PPA. When I run it I get the error below. This is by running it through gdb: Starting program: /usr/bin/digikam /usr/bin/digikam: error while loading shared libraries: libcxcore.so.2.1: cannot open shared object file: No such file or directory [Inferior 1 (process 29894) exited with code 0177] What should I do to find the error and fix it? I can see that somehow libcxcore.so.2.1 is wanted but not found. Is this an error of the PPA, or can I simply point it in the right direction? Can I raise an issue with the PPA creator through launchpad? Some next steps would be quite helpful.

  • Integrating Azure ServiceBus and SharePoint 2010

    - by Sahil Malik
    SharePoint 2010 Training: more information My new article is finally online. I had been waiting for this for a while. The thing is, AppFabric became .NET 4, and left SharePoint 2010 behind. But fear not, we have REST API. But that brings up interesting challenges of how we can integrate Azure Service Bus with SharePoint 2010 (yes 2010, not vNext – I’m not giving NDA information out you fool), the design patterns you can use, figuring out challenging issues like security, sessions, and just app design patterns instead. Well, I hope you like my next article, SharePoint Applied: Azure ServiceBus and SharePoint 2010 Enjoy! Read full article ....

  • Brightness issues on MSI GT683

    - by Mitu
    I'm experiencing brightness related issues on my MSI GT683 (Intel Core i5-2410M, nVidia GeForce GTX 560M, Ubuntu 12.04 LTS x64, nVidia driver version 295.40). To start with, when I open brightness settings, the slider is working incorrectly - screen is the dimmest on about 1/3 of a bar, moving it to the left side increases brightness. Next, while pressing the keyboard buttons (Fn+up, Fn+down), brightness changes incorrectly - sometimes 2 steps up/down, but sometimes it's totally irregular - ex. in order to set the lowest brightness, I have to set the maximum, then hit Fn+down, then Fn+up. (after 2 moves from 8 to 2... What's even more strange, while changing brightness from keyboard on boot and on login screen, it works perfect. Tried adding acpi related switches to GRUB, but the brightness settings wouldn't work at all. Any help appreciated.

  • Mount an image created from ddrescue

    - by oshirowanen
    I know this question has been asked before, but following those answers does not seem to work for me. I have created an image of a USB stick this is on my laptop harddrive. How do I mount this image? The command I used to create the image was: ddrescue --no-split /dev/sdb usb_recovered usb_recovery_log What am I supposed to do next? Mount it? Fix it then mount it? Mount it then fix it? And how? UPDATE: What I want to recover are the files in the image. How? I don't know as I have tried testdisk and it can't find partitions, and I have tried fdisk and it can't find a partition table in the image either.

  • How a .NET Programmer learn Big Data/Hadoop? [on hold]

    - by Smith Pascal Jr.
    I have been ASP.NET developer for sometime now and I have been reading a lot about Big Data- Hadoop and its future as to how it is the next technology in IT and how it would be useful to create million of jobs in US and elsewhere in the world. Now since Hadoop is an open source big data tool which is managed by Apache Server Foundation Group, I'm assuming I have to be well aware of JAVA - Correct me if I'm wrong. Moreover, How a .NET programmer can learn Big Data and its related technologies and can work professionally full time into this technology? What challenges and opportunities does a .NET professional face while changing the technology platform? Please advice. Thanks

  • What's missing in ASP.NET MVC?

    - by LukaszW.pl
    Hello programmers, I think there are not many people who don't think that ASP.NET MVC is one of the greatest technologies Microsoft gave us. It gives full control over the rendered HTML, provides separation of concerns and suits to stateless nature of web. Next versions of framework gaves us new features and tools and it's great, but... what solutions should Microsoft include in new versions of framework? What are biggest gaps in comparison with another web frameworks like PHP or Ruby? What could improve developers productivity? What's missing in ASP.NET MVC?

  • Login crash loop

    - by dawmail333
    After about the second/third batch of updates on a fresh install of Ubuntu 12.04, I end up getting stuck in an infinite login loop: I enter my password, screen goes black and shows me the end of the initialisation messages (including things like CUPS initialising), and then the greeter reappears. Kicker is, as I'm using gnome-shell, I just decided to uninstall LightDM, ubuntu-desktop and unity-greeter, using GDM as my manager, and the problem still happens in exactly the same manner. I'm lost even as to where to start looking - Xorg logs, LightDM logs (before I removed it), syslog and dmesg logs have held no unusual information at all. I have a TeX assignment due next week, and reinstalling Ubuntu every time I want to work on it is not going to work (nor is using TeX on Windows ;). Anything else I should try?

  • 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.

  • Great User Group if based near Gloucester + Links from Entity Framework 4.0 session

    - by Eric Nelson
    I had a really fun evening doing “my final” EF 4.0 session last night (26th May 2010) at GL.NET based out of Gloucester (although secretly I made it into a IronRuby and Windows Azure session). They are a great crowd and Jimmy makes for a fantastic host + it is a very nice venue (Symantec offices in Gloucester, lots of parking, good room etc) + free pizza + free SWAG + trip to pub afterwards (the topics were very varied!). What more could you ask for? The next session is June 16th and will be on multi-tenanted ASP.NET MVC and comes highly recommended.

  • What's new with Java technology? Java Embedded

    - by hinkmond
    As this article points out, Java Embedded is a safer, more robust and easier to develop platform for small networked devices. So, get ready for good things to come from Java Embedded... See: Java Embedded: Next New Thing Here's a quote: Through the past few years the industry as we know it has seen a big boom with the mobile and cloud revolution. Today, there has been an enormous amount of buzz around machine to machine (M2M) or the "Internet of Things," since we are moving into a state where everything is going to have to be interconnected and will have to properly communicate together... Today, Java Embedded provides that platform. I like it! As long as there's no Zombie Apocalypse, I think Java Embedded has a great future! Hinkmond

  • New Exam Score Report Process Coming Soon

    - by Paul Sorensen
    Hi Everyone! I want to give you a preview of a process change that will be coming in the next few weeks. We will soon announce a change in the way that Oracle certification candidates receive their exam scores and score reports (after they take an exam). Once the change occurs you will need to have an Oracle Web Account (in order to access your exam score). This is the account that is used to log into the Oracle website for things such as OTN access, software downloads and other Oracle services. If you already have an Oracle Web Account then you are already in good shape! If you do not have an Oracle Web Account the you should create one now (in preparation for this change)!  Look for additional announcements and detailed information in the coming weeks. Thanks,
