• Installing RVM on 11.10

  - by Guided33

  I have been trying to get RVM properly installed on my system for 10 hours. The problem is, that when ever I run the command to download the install script I get this: edu@edu-VirtualBox:~$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer) mkdir: cannot create directory `/usr/share/ruby-rvm': Permission denied If I run the command with sudo, I can get it installed, but then that leads to a whole host of other issues. Every tutorial I read says that you should not be installing rvm with sudo for a single user install. Why can I seem to get it installed without running sudo?

• ASP.NET Website Security Tips and Tricks

  This is a tutorial on how to secure your ASP.NET Mono website. Securing an ASP.NET website that runs in Mono is very different from securing an ASP.NET website hosted in a Windows environment because an ASP.NET Mono website runs on a non-Windows server such as Apache or Lighttpd and on an operating system such as Linux Unix. Thus the principles of securing a website in Apache server can be applied to securing an ASP.NET that runs in Mono.... Comcast?

• I need advice on creating animal 3D walk cycles in XNA

  - by Zetar

  I want to purchase a number of 3D models from TurboSquid and animate them in an XNA game. I wrote a lot of games from 1985-1999 and have recently become involved with XNA. Now I would like to port one of my old games to the XBOX. I do have a background in 3D animation; but that was years ago. What is the current method for animating a walk cycle with a 3D model and using it inside XNA? Is there a book, software or a tutorial that you can recommend? Thanks in advance and sorry for such a broad and currently naive question.

• Dual boot windows 8.1 acer V3-571G with Ubuntu 13.10

  - by tara512

  I am trying to dual boot my acer which came with windows 8 pre-installed. I tried using the tutorial here doing it the simple way but when I load Ubuntu from my transcended flash drive it says that there is no other operating system installed. I tried partitioning my hard drive but I seem to have 3 recovery partitions and even though I have 485GB free I can only allocate 100GB to the new partition. I would like to have most of my hard drive allocated to Ubuntu and just use the windows for programs like microsoft office.

• Is it only possible to display 64k vertices on the monitor with 16bit?

  - by Aufziehvogel

  I did the first 3D tutorial over at riemers.net and stumbled upon that my graphic card only supports Shader 2.0 (Reach profile in XNA) which means I can only use Int16 to store the indices (triangle to vertex). This means that I can only store 2^16 = 65536 vertices. Also I read on the internet that you should prefer 16-bit over 32-bit because not all hardware (like mine) does support 32-bit. Yet, I am wondering: Do really all game scenes get along with only so little vertices? I though already faces of people used a lot of polygons (which are made up of vertices?). It’s not relevant for me yet, but I am interested: Do game scenes use only 65536 vertices? Do you use some trade-off to display more (e.g. 64k in GPU buffer rest on RAM) Is there some method to get more into the GPU buffer? I already read on some other posts that there seems to be a limit of 64k per mesh too, so maybe you can compact stuff to meshes?

• Is there a consolidated API reference for the Firefox browser.xul?

  - by cxw

  I have used Greasemonkey many times and am stepping up to Firefox extension development. Is there a consolidated reference for the variables, functions, and anything else that is available to overlays on browser.xul? Besides gBrowser, I note from the source that there are at least gNavToolbox, gURLBar, and gNavigatorBundle and would like more information about what services they provide. I have looked through the XUL School and XUL Tutorial on MDN, searched MozillaZine, and browsed the Jetpack documentation without finding anything but references to gBrowser. I have also looked at the code snippets referenced elsewhere (e.g.) and found specifics, but nothing that puts all the information together in one place. Is there such a reference?

• iOS: game with facebook challenges

  - by nazz_areno

  I created a game for iPad and I want to challenge my facebook friends. I follow the iOS tutorial in "facebook dev docs", with the "Smash game", but it doesn't explain how to challenge a friend directly to a game. I will explain with an example: I want to start a new match and I want challenge a friend on facebook. Then I send him a request to install the app and when I detect that its app is installed I send him a request to play vs me. Then, when I finish the match I sent him my result and my friend do the same thing. But if I and my friend don't finish the match it is not possible to send another challenge. This scenario is not explained by facebook sdk. Is it necessary to use another instrument to do this situation?

  I must write a multiplayer pong game for the school. Where are thousand of rooms and where two players can go in to a room and play together and collect points.

• How to speak to a computer

  - by SalemSeven

  I am a self taught.. NEW..programmer. The language I chose was Objective-C so I can write for Apple products. I have learned the hard way that Objective-C has a steep learning curve but have forced myself to look at it over and over until I get it. I feel I am completing one major step and that is becoming very comfortable with the syntax and now as I enter the next big step...finding out what is possible with a computer language - I am thinking that all software is just developed within the confines of classes-loops-booleans-IF/OR statements-variables-etc. Is that a true assessment? When thinking of software in my head do I just need to learn to convert it all to arrays-loops/variables/classes - IF/OR statements - etc? Sorry if this question sounds funny but I am just learning how to take the language in my head and talk (what I think is) the language of a computer. Is there a good book or tutorial that helps illustrate how to speak computer speak?

• What is the standard way of delivering HTML5 games to portals and such?

  - by Bane

  Let me explain what I mean by "standard way of delivering"... Think about Flash games sites. Flash games can be delivered as a single file, either hosted by the site, or, I guess, provided by someone else. HTML5 games, on the other hand, don't have something so standard. Usually, they have their own page, and portals just link to that page. I think that it greatly hinders the purpose of that portal, because, well, you want people to stay on your site and look for other games. Now, I think that a some kind of iframe way of delivering games would help solve this problem greatly. I saw some games doing that, and they were often included on tutorial sites to show a live example, which is obviously a great thing. So, is there a standard at all? Any suggestions? Can you create a game that just preloads itself in an iframe (I heard something about a "single document" or something)?

• How to create a simple side scroller game

  - by D34thSt4lker

  I'm still pretty new to game programming and any tutorial that I have worked with stuck to only games with the initial screen. I want to start creating my own games but there are a few things that I still need to learn. One of them is how to create a game that side-scrolls. For example; Mario... Or ANY type of game like that... Can anyone give me a small example to create something like that. I'm not asking for any specific language because currently in school I am learning javascript but I know some c++/java/processing/objective-c as well. So any of those languages would be fine and I could probably implement it in any of the others... I have been searching for some help with this for a while now but could never actually get any help on it. Thanks in advance!

• Career in Artificial Intelligence [closed]

  - by Rohit S

  AI has many branches and seems like it has a bigger scope. I have seen a tutorial of Neural Networks and I'm a little confused whether Neural Networks is another branch of AI or it is a technique which is being used in branches of AI. I am mainly interested in creating software like Neural Networks that can be trained for doing a task. I like to make things automated with programming languages. So can I start with Neural Networks? And also a very important matter: what will be the scope of a job in future and in which companies?

• Hadoop:Only master node does the work

  - by user287722

  I've setup a Hadoop 2.2 cluster with 1 master node(namenode and secondary namenode) and 3 slave nodes(datanode and namenode on each one).All of the machines use Linux Mint 64bit. When I run my MapReduce program, writen in Java, I can only see that master node is using extra CPU and RAM. Slave nodes are not doing a thing. I've checked the logs from all of the namenodes and there is nothing wrong with the namenodes on slave nodes. Resource Manager is running and all of the slave nodes can see the Resource Manager. I used this http://n0where.net/hadoop-2-2-multi-node-cluster-setup/ tutorial to configure my nodes. Datanodes are working in terms of distributed data storing but I can't see any indication of distributed data processing. Do I have to configure the xml configuration files in some other way so all of the machines will process data while I'm running my MapReduce Job?

• Implementing RAID 1 in Ubuntu 10.04 Desktop [closed]

  - by Dibyendra

  I found many resources on implementing RAID 1 using two disk drives. But, I am confused while implementing RAID 1 using 4 RAID disks. Can we use two disks for storage and two for mirroring using RAID 1? I couldn't find the way to create RAID disk using gparted tool in Ubuntu 10.04 Desktop version. Maybe, the desktop version doesn't support RAID. I am trying to implement RAID on the existing Ubuntu installation? I have added 4 X 2TB HDD in the system and I want RAID 1 to be implemented in these 4 drives with 2 drives for storage and 2 devices for mirroring. Any help would be appreciated. Thanks! Updated: I installed Ubuntu 12.04 LTS and followed the following tutorial and it works now: www.youtube.com/watch?v=z84oBqOxsD0

• How to learn an API

  - by inovaovao

  When I find some interesting project (e.g. on GitHub) I often would like to use it and try it out to see how it works, but if there isn't a good documentation or some kind of tutorial it's hard to figure out how to use it. So my question is: how do you approach such a situation? How do you figure out which classes are important and how to chain them to put them to use? What would you look at first? An advice I found is to look at the tests (if there are any). But if there are unit tests for every class, how do you know which ones to look at first?

• phishing attack. Where do I start the cleanup?

  - by Suz

  I'm a newbie webmaster. I've got a domain and a site... and no clue about the web (I'm OK with files and programs... ) I got a message from google that my site is a possible phishing site, with a link the the suspect page: http://www.mydomain.com/~phishers/Paypal/us/Confirm.php needless to say, I didn't put that up. Can someone point me to a good tutorial on what to do now? I'd like to figure out what happened so I can defend against it the next time around. How do I identify what kind of attach this is? Also, what is the tilde doing in the URL path? I couldn't find any path like this on my hosting account, so I'm not entirely sure how to delete it.
