setting up for programming using webGL - webgl

I am having problems for setting up my laptop to program using webGL.
I am using mint linux 16. I tried installing nodejs because the webGL is javascript program but it seems not working. I am reading a book called WebGL programming guide and try to run an example in the book to make sure that my laptop is set up for webgl. One of the very first example in the book uses javascript libraries such as webgl-utils.js, webgl-debug.js... but I can find those libraries. Can anyone help me please??

I'd check to see if your video card or browser is supported.

When using opencl with torch, lua uses integrated graphics not dedicated gpu

I am using Andrej Karpathy's code to train a rnn. When I give the flag "-opencl 1" to tell it to use an opencl gpu, it uses integrated graphics and nothing else.
I tried reinstalling cltorch and using different flags, but nothing has seemed to work. To add to this I can't see if my gpu is under load because I'm on macos. I looked through the code and I could't find any errors, but I have little experience with lua.
Code can be found here: https://github.com/karpathy/char-rnn.
I expect with the flag "opencl 1" or something to the like, my radeon pro 560x will be used to train on my dataset and not my cpu or integrated graphics.
When reading instructions I thought just -opencl flag needed to be used but it turns out -gpuid needs to be used in conjuction with it as well. This was also after a reinstall of torch and opencl drivers, so that could have been a problem as well.

opencv not able to run some advanced image processing code

i am using visual studio 15
some basic blurring and filters are running perfectly but on some codes such as blending and dct techniques are not running
Can anyone please help me
At this point its probably best to create your own compiled library tools for MicroSoft Visual Studio 15. Here's a how to guide. That guide covers all the steps and starts with the most current code on Github.
Also note there are many tutorials out there on OpenCV. Many parts of the OpenCV library have been update, or replaced. You have to be careful that the commands you are using are valid in OpenCV 3.x
Compile your own, run a few simple programs.
If you want specific help here, you MUST post your code, and the errors you are seeing.

WebGL troubleshooting

I am using ubuntu 12.10 OS. I would like to learn WebGL programming.
All at a sudden my WebGL stopped working. Initially firefox provided 3d way of looking at webpage elements. But now it's not working. Saying "Could not initialize Tilt, please check the
troubleshooting information available at http://get.webgl.org/troubleshooting" in an alert box.
Any help appreciated.
I had this problem, in my case while webgl.disabled=false, webgl.force-enabled=true helped.

porting wireshark to qnx based system

I am a newbie to industry and as a part of my internship I have been assigned the above project.I have no experience in how to go about porting a particular application to a different OS.
So far,i have tried to understand the basic structure of a component(thats what an application is called IOS-XR) but as far as I can understand,porting wireshark will also require porting the libpcap lib to XR.
Can someone please shed some light as to how should i go about approaching it?
I know nothing about QNX;
However, I will note that Wireshark has a lot of dependencies on various libraries:
Some examples;
libgLib
libgtk
libffi-5
libfontconfig-1
libfreetype-6
libintl-8
libjasper-1
libjpeg-8
liblzma-5
libpixman-1-0
libpng15-15
libtiff-5
libxml2-2
...
Are these libraries available on QNX ?
With respect to libpcap:
libpcap is needed for capturing files. If not available, it certainly would need to be ported. I could imagine that this might be a large effort given that presumably the code is presumably quite dependent upon the exact OS capabilities to get access to the network level data.
For information about developing Wireshark (on Windows and *nix) see the
Wireshark Developer's Guide.

Clojure iOS Development

Over the past months, I've pretty much fallen in love with Clojure and refuse to use anything else.
I am aware that there is ClojureScript, which uses Google Closure to compile a subset of Clojure to JavaScript.
Is there anything similar in the works for Objective-C/Cocoa?
I would love to be able to prototype applications in Clojure, and then get an iOS app out of it.
[I'm perfectly fine if this prevents me from all the low level details of iOS -- I don't need access to any low level details (say pointer arithmetic) that I can't do in Java -- I just want to be able to easily transform my Clojure Apps onto the iOS]
You can run clojure on iOS by compiling clojure to scheme, https://github.com/takeoutweight/clojure-scheme
There's one more option (warning: haven't tried it yet):
https://github.com/oakes/lein-fruit
This Leiningen plugin translates Java bytecode to native code for iOS. And there's even IDE that has it built-in:
https://github.com/oakes/Nightcode
I've just discovered las3r which is a Clojure port to the ActionScript (the language behind Flash) runtime. Since Flash/ActionScript can now develop for iOS (I'm in the process of writing a game right now. It's not wonderful, but it's quite usable), this may present a path to writing Clojure applications for iOS.
DISCLAIMER: I haven't tried this. I've just barely discovered las3r, haven't even downloaded it. and have no idea if it's good or terrible. I don't know how awful the speed will be. I know nothing.
Still - it's an intriguing idea, isn't it?
There is Re-Natal a simple command-line utility that automates most of the process of setting up a React Native app running on ClojureScript.
