Zyxel PMG3000-D20B firmware image files

The firmware of this GPON ONT SFP module can be updated using the web interface (Management | Update Software):

The web interface only accepts image files with a special header. These can be created by adding the header to a flash dump.

Implementing a jq REPL with fzf

Update: I created jq-zsh-plugin that does this.

One of my favourite tools of my trade is jq. It essentially enables you to process json streams with the same power that sed, awk and grep provide you with for editing line-based formats (csv, tsv, etc.).

Another one of my favourite tools is fzf.

Real depth in OpenGL / GLSL

http://olivers.posterous.com/linear-depth-in-glsl-for-real

So, many places will give you clues how to get linear depth from the OpenGL depth buffer, or visualise it, or other things. This, however, is what I believe to be the definitive answer:

This link http://www.songho.ca/opengl/gl_projectionmatrix.html gives a good run-down of the projection matrix, and the link between eye-space Z (z_e below) and normalised device coordinates (NDC) Z (z_n below). From there, we have

A   = -(zFar + zNear) / (zFar - zNear);

B = -2zFarzNear / (zFar - zNear);
