To proceed with the deployment to S3, we will install these plugins: ember-cli-deploy-s3-index: It uploads the index.html to S3 with revision information, and activates it ember-cli-deploy-s3: It uploads the assets (js, css and other media files) to S3 As they are Ember addon you can easily i...

ROT13 is a special case of Caesar cipher, with a 13 shift. Only letters are changed, and white-space and special characters are left as they are. What is interesting is that ROT13 is a reciprocal cipher : applying ROT13 twice will give you the initial input. Indeed, 2 * 13 = 26, the number of lette...

Below is an example of Gstreamer pipeline embedded in a simple gtk window. When run, a small window should appear like this: import gi gi.require_version('Gtk', '3.0') gi.require_version('Gst', '1.0') from gi.repository import Gtk, Gst Gst.init(None) Gst.init_check(None) class GstWidg...

When the select statement is executed, it displays the given items prefixed with a number and then displays the PS3 prompt: export PS3=" To choose your language type the preceding number : " select lang in EN CA FR DE; do # check input here until valid. break done

Encapsulating an OpenGL object in C++98/03 requires obeying the C++ rule of 3. This means adding a copy constructor, copy assignment operator, and destructor. However, copy constructors should logically copy the object. And copying an OpenGL object is a non-trivial undertaking. Equally importantly,...

Here's how to translate objects in P3D: size(200, 200, P3D); //Starting P3D renderer fill(255, 0, 0, 150); //transparent red rect(10, 10, 100, 100); //first rectangle fill(0, 0, 255, 150); //transparent blue translate(50, 50, 50); //translate x, y and z by 50 pixels rect(0, 0, 100, 100); //sec...

There are three functions for 3D rotation: rotateX(angle), rotateY(angle) and rotateZ(angle) for rotation in their respective axes where angle is in radians. size(200, 200, P3D); //Starting P3D renderer fill(255, 0, 0, 150); //transparent red translate(width/2, height/2);//translate to centre, ie...

(Note: There are many IDE, toolchain and library which are ready-to-use with STM32. The following setup requires minimal effort to get it work, but it is only one of the many. Feel free to explore others, it is not the purpose of this example to force anyone to use the tools that will be used here.)...
