OpenCV Face Recognition

Tuesday, May 15th, 2018


OpenCV is an Open Source computer vision library that, among other things, can recognize faces, including eyes and smiles.

I set out a few weeks ago to build some prototypes with the library, to get an idea of how it works. I have created 3 prototypes, one that detects faces, one that detects eyes and one that detects smiles. All the projects are on GitHub here and they all use Python 3.


OpenBSD 6.2 VPN Endpoint for iOS and macOS

Sunday, February 25th, 2018


The following instructions describe how to remotely connect to a network over an IPsec / L2TP VPN through an OpenBSD server, using native clients on macOS and iOS.

There are many VPN appliances commercially available that provide a nice UI and often come with an expensive support contract. If you are willing to roll up your sleeves a little and don’t mind using the command line, it is possible to create your own VPN server with OpenBSD.


OpenBSD 6.0 VPN Endpoint for iOS and OSX

Saturday, December 10th, 2016

Being able to remotely connect to my home network over VPN has always been on my ‘nice to have’ list. It allows easier access to resources and direct ssh (rather then hoping through the gateway). I have recently updated the OpenBSD server I used for VPN to 6.0 and thought I would share the configuration and settings.


Laser Cut USB Key Case

The Why

I have a collection of USB keys each different version of OS X and Ubuntu so that I can do a complete reinstall from scratch. The collection was rattling around in my desk drawer, which was annoying.

What I really wanted was to put them in a case, ideally one that matched the other dvd and cd cases.

Messing around with a Kinect, OpenNI, NiTE led me to a node.js app called Nuimotion.

In an effort to document successful install of all the required packages I created these instructions.


Burning cds in OS X from the Command Prompt

Saturday, January 5th, 2008

Looking for a quick way to burn an ubuntu linux cdrom, I found this quick way of burning an iso image from the command line:

hdiutil burn cdrom-image.iso

Apparently this will also do OS X dmg image files too.

For those like myself who like the command line tools, this is a good one to know about.
