HackLab.TO is having a job fair!

We know a lot of people who work in various tech fields. Some people are looking to fill positions at their companies, some are looking for new jobs, and others are finishing university and looking to break into the field. We’d like to help get you in touch with each other.

Bring your resume: we’ll have representatives from companies actively looking to hire people. Bring your business cards: we’ll have a lot of people from the local tech community who are interested in professional networking.

Attendance is free to people who are job hunting, although we ask that people use our ticketing system to RSVP– our space is limited, and we don’t want to be overwhelmed! The event will run from 10AM to 4PM on April 4th, with no registration for specific time slots.

Spread the word, especially for companies recruiting or people looking for contract work– the more job opportunities available at the fair, the bigger of a success it will be.

During last week’s python class we got to the part in our wonderful textbook where the concept of recursion is introduced.  My friend Susan posted a witty line to my facebook feed regarding the teaching of recursion:

I normally teach recursion by checking to see whether they understand recursion, and if not, teaching recursion.

Within the class we have a variety of levels of experience with programming in general, and recursion in particular.  I’m curious to hear peoples’ favourite recursion teaching tools, examples, or other witticisms.  What’s your favourite programming problem to solve recursively?

After a few hours or hacking the old Red Roomba, and failing to fix or workaround the cliff hanger sensor it was time to get some success.

Elmood went out and got me a ULN2803AP chip, which I could use to glue together the Arduino and the tri colour LED bar. I then used some of the arduino examples to pulse and colour and mess around a bit.

The next step, perhaps using I2C to control individual bars (I have 10) and line them up on the stairway!

We now have a webcam pointed at the sign….

Andrew has written a detailed blog post about making the LED sign work.
