  • How to set density for each shape in PhysX 3.1

    - by hywei
    I'm using PhysX 3.1 as my game's physics engine. One requirement is that I need set different density for each shape(there are server shapes for my single rigid actor). I know that the shape's density can be set by NxShapeDesc::density in PhysX 2.8, but I can't find such interface in PhysX 3.1. I know that the mass properties can be set in PhysX 3.1 just as the snowman example in the SDK, but I don't know whether there exists a direct interface to set density for each shape.

  • Wifi is connected but internet not working?

    - by Philip
    I have a lenovo x230 running ubuntu 12.04lts. I've been using it just fine for a while, but all of a sudden the internet's stopped working. It's connected to the router just fine (I can see the antenna bars saying it's connected) but when I try to go to a webpage, it's just loading forever. I've tried the fix listed here (http://ubuntuforums.org/showthread.php?t=1985079) but it hasn't done anything (the instructions are a little confusing though). I'm booting windows 7 right now and the internet works just fine when I'm on windows, so I know it must be a problem with ubuntu. I haven't touched any network settings before this problem happened, and I've been using it just fine for months, so I don't know why I'm getting this problem all of a sudden. Oh and I haven't updated anything in a few weeks (you know when the update manager pops up every so often listing all the things there's an update for) so I know it's not some update that broke it.

  • Can't ping external websites

    - by Frantumn
    I can't ping google.com with my virtual ubuntu 12.04 server. I have set up a proxy URL in my /etc/apt/apt.conf file and it says Aquire::http::proxy http://urlname.com:9999; Now, I don't know a lot about how the proxy works, but I do know when we use it on windows VMachines it's a pac script that we place in internet explorer LAN settings and it automatically detects the script and gives internet access. I tried including the 9999/proxy.pac in the apt.conf URL and it didn't seem to work any better. Would ubuntu know how to handle a proxy.pac assuming it was created for windows? Should my URL include the .pac or just end after the port numbers? I've tried both without sucess, but I would like to know. A quick test to ping a fellow co-workers' PC was sucessful. So I can see network computers, but not google. or other internet sources.

  • Consultant in a firm that doesn't understand the tech!

    - by techsjs2012
    I got the job as a Consultant in a firm that has 3 other programmers. My job is to rewrite all the old system in Java, Spring etc but the staff programmers only know perl and the manager does not know any programming. I am trying to get them to understand that I have 6 projects to rewrite here but no one has design docs or spec. the staff programmers never had to write any documents. Plus I cant get the manager to understand the new java tech stuff.. he keeps asking some of the staff for views on things but the staff don't know it or understand it. Where do I go from here to make the manager understand that the staff programmers or someone has to write a design document so I know what to build. or if I have to write the documents how do I get the information?

  • How do you write a macro for a special character in LibreOffice?

    - by JasperKov
    Does anyone know how to write a macro for a special character? I know LibreOffice currently doesn't have a way to set a special character to a keyboard shortcut. However, I want to work around this with a macro. My plan is to create a macro for a special character then set a keyboard shortcut to that macro. Problem is I don't know the first thing about writing a macro. Any one have a template or something that works? I also know about the compose key, but I guess I am lazy and want to actually insert special characters with as few keys as possible.

  • How do I fix a terrible system error on ubuntu 12.04

    - by Anonymous
    I don't know what happened, but one day my computer had some sort of a system error and could no longer update itself. The software center will not open, it will begin to initialize and then a message pops up saying theres a system error and needs to shut down the software center. Then another box pops up after I go to report it saying it was unable to identify source or package name. I also can't extract a zipped folder to anything, or reinstall Ubuntu from a USB boot drive anymore, it keeps telling me my my computer isn't compatible when I know for a fact it is, because thats how I got Ubuntu on here in the first place. the only thing I know about this error is that a message popped up after I went to check for updates saying to report the problem and include this message in the report: 'E:malformed line 56 in source list /etc/apt/sources.list (dist parse)' it also called it a bug. I just want to know how to either get rid of the bug completely or find some way to be able to reinstall Ubuntu again. I know it's not a lot of information, but It's all I can give. Sorry.

  • How to overwrite Ubuntu with Windows 7?

    - by Will Cowled
    So I have a Windows DVD and it works. But when it gets to the part when it says "Upgrade" or "Custom" I click on custom and at the bottom it says cannot install over it because Windows 7 can only be installed on an NTFS drive? I know that Ubuntu formatted my partitions into one big on that's an ext4. What can I do? I know that I can maybe create a 30-50 GB partition that's an ntfs then when I go into windows I can format the Ubuntu one and combine them but I don't know how to make a partition much less make a big partition in the "GParted" program? So any ideas would be very helpful. I know how to do anything with a hard drive using the default program that comes with Windows 7 but I feel like a mouse in a maze when I open GParted.

  • Most supported/easiest to get started gamedev language?

    - by user1009013
    In what language are the most libraries/frameworks (like lwjgl for Java, XNA for C#)? What language is the easiest to start making a game (very easy to get a 3D-environment rendered)? What language has the friendliest learning curve? Say I want to make a game and I don't know any programming languages, I want to develop for any platform(so don't give the answer "the one you know best/the platform you are working on"), then what is the best language to start with. I get this question a lot "I have this and that ideas for a game and want to make it, what language should I use"(mostly asked by beginning programmers), but I don't know how to answer that. The answer "use the one you are most familiar with", because sometimes they don't even know a language yet... I am not asking for someone's personal opinion, but an objective list of what languages are the easiest/most supported/have the most/best libraries/frameworks to get started with gamedevelopment.

  • Defining and selecting an area from an image

    - by meth0d_
    I want to create a game, where the world is loaded from an image file, much like Paradox Interactive does it for their games. If I have this image: Then the red, green, blue, cyan, magenta, white, black and grey should be different provinces. I know how to loop through them, and check if it's a new province, the problem is that I don't know how to define the region of the province for selection: I don't know how I can load in data, to make sure you can click anywhere on that province, and make sure it gets selected.

  • What is the package name for JVM?

    - by JohnMerlino
    If I want to know if skype is installed, I would type this: viggy@ubuntu:~$ apt-cache policy skype skype:i386: Installed: 4.0.0.8-1 Candidate: 4.0.0.8-1 Version table: *** 4.0.0.8-1 0 100 /var/lib/dpkg/status Or if Eclipse is installed: viggy@ubuntu:~$ apt-cache policy eclipse eclipse: Installed: (none) Candidate: 3.7.2-1 Version table: 3.7.2-1 0 But let's say I want to know if the Java Virtual Machine is installed. How would I know what to pass to apt-cache policy? For example, you might not know what to pass to apt-cache policy for some programs: viggy@ubuntu:~$ apt-cache policy java N: Unable to locate package java viggy@ubuntu:~$ apt-cache policy JVM N: Unable to locate package JVM

  • How do I install the latest version of Mupen64?

    - by Uikri
    Alright, I can't figure out how to install Mupen64 on Ubuntu 12.04. I'm gonna be moving in ~2 days with no internet connection for an indefinite amount of time, so that's why I'm asking for answers here instead of figuring it out myself (I don't have time right now to sit and fiddle with figuring out emulators). I'd like to know how to properly install the latest version of Mupen64 (Stable. No beta or anything like that) and how to be able to use a controller with it. I've heard rumor that the latest version of M64 no longer has a GUI, but that there are ways to add a GUI to it after installation, so I'd also like to know how to add the Mupen64Py UI to it. I am not totally Ubuntu savvy. I do not know how to compile stuff from source, I don't necessarily know a lot of terminology, I'm not very handy with the terminal, etc. So it would be helpful if you explain each step in an easy to understand manner. Thanks in advance to anybody who helps out. EDIT: I've already seen How do I install mupen64plus?, just so you guys know. I just need instructions that are more detailed. Also, thanks for the edit, Jorge Castro! I guess I really should have properly formatted my question ^^;

  • What are the app file size limitations for different smartphone OSes & carriers?

    - by Nick Gotch
    I know the iPhone App Store limits how large an app can be in general and there are also limitations with AT&T over the size it can be to transmit over a data plan vs WiFi. I have no idea what, if any, these limits are for Android apps and what I'm finding online is a mix of different numbers. Does anyone know these numbers definitively? The Android game I'm porting is in the 20-30MB range and we'd like to know if we need to further reduce its size.

    - by nore
    There is a guy who calls himself c/c++ programmer, but what does he actually know? What knowledge about c++ does he have because there are so much to know about c/c++. So he knows the core language? He knows visual c++? He knows how to program with WIN API? He knows how to program in linux with gtk? Network programming? The real question is: What do you need to know, to be called a c/c++ programmer ,because I know c and I really do not feel like I own the power of programming... please illuminate my path.

  • UI font has rendering glitches in GNOME Shell

    - by user353889
    I don't really know how to describe this problem in English. A picture can say more words - look at the tabs at the top of the linked image. The current font settings are shown as well. I don't know what basic info I should provide so if something missing, please tell me. Ubuntu 12.04 GNOME Shell 3.4.1 I know, a reboot can make everything normal but I'm looking for a more permanent solution that can fix this problem (or bug). Update Thanks for Fitoschido, I finally know what keyword I could use for googling. I think it's a bug of gnome shell. https://bugs.archlinux.org/task/34847

  • Mahout - Clustering - "naming" the cluster elements

    - by Mark Bramnik
    I'm doing some research and I'm playing with Apache Mahout 0.6 My purpose is to build a system which will name different categories of documents based on user input. The documents are not known in advance and I don't know also which categories do I have while collecting these documents. But I do know, that all the documents in the model should belong to one of the predefined categories. For example: Lets say I've collected a N documents, that belong to 3 different groups : Politics Madonna (pop-star) Science fiction I don't know what document belongs to what category, but I know that each one of my N documents belongs to one of those categories (e.g. there are no documents about, say basketball among these N docs) So, I came up with the following idea: Apply mahout clustering (for example k-mean with k=3 on these documents) This should divide the N documents to 3 groups. This should be kind of my model to learn with. I still don't know which document really belongs to which group, but at least the documents are clustered now by group Ask the user to find any document in the web that should be about 'Madonna' (I can't show to the user none of my N documents, its a restriction). Then I want to measure 'similarity' of this document and each one of 3 groups. I expect to see that the measurement for similarity between user_doc and documents in Madonna group in the model will be higher than the similarity between the user_doc and documents about politics. I've managed to produce the cluster of documents using 'Mahout in Action' book. But I don't understand how should I use Mahout to measure similarity between the 'ready' cluster group of document and one given document. I thought about rerunning the cluster with k=3 for N+1 documents with the same centroids (in terms of k-mean clustering) and see whether where the new document falls, but maybe there is any other way to do that? Is it possible to do with Mahout or my idea is conceptually wrong? (example in terms of Mahout API would be really good) Thanks a lot and sorry for a long question (couldn't describe it better) Any help is highly appreciated P.S. This is not a home-work project :)

  • How to create a large level game?

    - by Siddharth
    I want to know how to create a large game which has more than one level in it and those levels are loaded from the xml file. In my game I have many objects for each different level which I have to load when use click on it. At present for example my game contain 20 levels and now I was loading all the graphic object for all 20 levels. But the correct way was that only load graphic of that particular level only. So I don't know how to do that. So please explain this by providing game example. At present I was creating a class for each my game object image by extending sprite to it. I know it was not a suitable way so provide guidance on it. Basically I want to know how to create large games in andengine? Please help me about that because it will provide help to other community member also because andengine did not have proper documentation for learning developer about how to manage large game?

  • Taking too long to get skills for entry level programmer position [closed]

    - by greenonion
    I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

  • Mac OS X: How to change the color label of files from the Terminal

    - by Svish
    Is there a way I can set the color label of a file to some color when in the Terminal? I know that the following command lists some info about what the color currently is, but I can't figure out how to do something about it. Like change it. mdls -name kMDItemFSLabel somefile.ext The reason I would like to know is that I want to recursively mark all files in a folder of a certain type with a certain color label (in my case gray). I know how to do the finding: find . -name "*.ext" And I know how I can run the command afterwards for each file using -exec, but I need to know how to do the actual labeling... I would like a solution that only involves commands built-in to Mac OS X. So preferably no 3rd party stuff, unless there is no other way.

  • How to start working in a team on a project? [closed]

    - by Adio
    Ok, for the first time in my life I am going to work in a team. The problem is that all the team members including me are junior developers and for all of us this is the first time we are working in a team. The problem is that we do not know how to start the project. We know a little about scrum and agile development, we have our user stories in place and our created project - which does not have even one piece of code - and now we are stuck and don't know how and what to do? All scrum books talk about scrum development but lack of the details like how to start. How my team will know what object I am using? How we will push the first piece of code and what it will be? Any help will be great. Books, articles, advice, or anything.

  • Which C# Book to take?

    - by Fischkopf
    I was searching for a book to learn C#, but now i'm kinda stuck. I found many people asking the same question, and many people gave answers, but there are so many books about C# that it is really hard to decide which one to take. Now i reduced my choice on two books, but I just can't decide between them. Namely, there are: Programming C# 4.0 and C# 4.0 In A Nutshell The first thing I want to know, are these good choices? I'm not completely new to programming, but I just didn't find the right language until know, but i think C# is the one I was searching for. I know all the bassic stuff from Delphi/Java/Python so I think i'm not a complete beginner in programming. Is there anyone out there that read both books and can cleary explain whats the difference between them? I haven't found many reviews and sort of, so I just don't know which one to chose. Or is there any book that is better suiting me?

  • What computer science topic am I trying to describe?

    - by ItzWarty
    I've been programming for around... 6-8 years, and I've begun to realize that I don't really know what really happens at the low-ish level when I do something like int i = j%348 The thing is, I know what j%348 does, it divides j by 348 and finds the remainder. What I don't know is HOW the computer does this. Similarly, I know that try { blah(); }catch(Exception e){ blah2(); } will invoke blah and if blah throws, it will invoke blah2... however, I have no idea how the computer does this instead of err... crashing or ending execution. And I figure that in order for me to get "better" at programming, I should probably know what my code is really doing. [This would probably also help me optimize and... err... not do stupid things] I figure that what I'm asking for is probably something huge taught in universities or something, but to be honest, if I could learn a little, I would be happy. The point of the question is: What topic/computer-science-course am I asking about? Because in all honesty, I don't know. Since I don't know what the topic is called, I'm unable to actually find a book or online resource to learn about the topic, so I'm sort of stuck. I'd be eternally thankful if someone helped me =/

  • `this` in global scope in ECMAScript 6

    - by Nathan Wall
    I've tried looking in the ES6 draft myself, but I'm not sure where to look: Can someone tell me if this in ES6 necessarily refers to the global object? Will this object have same members as the global scope? If you could answer for ES5 that would be helpful as well. I know this in global scope refers to the global object in the browser and in most other ES environments, like Node. I just want to know if that's the defined behavior by the spec or if that's extended behavior that implementers have added (and if this behavior will continue in ES6 implementations). In addition, is the global object always the same thing as the global scope? Or are there distinctions? Update - Why I want to know: I am basically trying to figure out how to get the global object reliably in ES5 & 6. I can't rely on window because that's specific to the browser, nor can I rely on global because that's specific to environments like Node. I know this in Node can refer to module in module scope, but I think it still refers to global in global scope. I want a cross-environment ES5 & 6 compliant way to get the global object (if possible). It seems like in all the environments I know of this in global scope does that, but I want to know if it's part of the actual spec (and so reliable across any environment that I may not be familiar with). I also need to know if the global scope and the global object are the same thing by the spec. In other words will all variables in global scope be the same as globalobject.variable_name?

  • Should I learn two (or more) programming languages in parallel?

    - by c_maker
    I found entries on this site about learning a new programming language, however, I have not come across anything that talks about the advantages and disadvantages of learning two languages at the same time. Let's say my goal is to learn two new languages in a year. I understand that the definition of learning a new language is different for everyone and you can probably never know everything about a language. I believe in most cases the following things are enough to include the language in your resume and say that you are proficient in it (list is not in any particular order): Know its syntax so you can write a simple program in it Compare its underlying concepts with concepts of other languages Know best practices Know what libraries are available Know in what situations to use it Understand the flow of a more complex program At least know most of what you do not know I would probably look for a good book and pick an open source project for both of these languages to start with. My questions: Is it best to spend 5 months learning language#1 then 5 months learning language#2, or should you mix the two. Mixing them I mean you work on them in parallel. Should you pick two languages that are similar or different? Are there any advantages/disadvantages of let's say learning Lisp in tandem with Ruby? Is it a good idea to pick two languages with similar syntax or would it be too confusing? Please tell me what your experiences are regarding this. Does it make a difference if you are a beginner or a senior programmer?
