This is my final year project for my bachelors degree in Electronic Engineering. The Conference Pi project involves designing a Raspberry Pi based voice conferencing system using mostly off the shelf components. The case, which houses the microphone array was designed in Autodesk Inventor and printed on a Makerbot Replicator 2. The design was inspired by existing VoIP devices.

How Universities Work
In one of my recent posts, I made passing mention of “increasing research productivity” at universities. This is a pretty vague concept, and touches upon a often misunderstood topic: How Universities Work. This post is likely to paint only a partial picture, but I’ve seen that it can sometimes be downright confusing to outsiders, so it bears writing up.

I've surrendered my passport to the Kazakhstan officials.
I surrendered my passport today. Any seasoned traveller knows: Never let someone take your passport. Stay out of trouble, and never disobey local laws. So if it turns out that local laws require you to surrender your passport to the police for the duration of your stay, that's a bit of a ...

This has been around for a decade, but I've just come across it for the first time: a delightful mock-kōan on the similarities between objects and closures in programming languages:

-----

The venerable master Qc Na was walking with his student, Anton. Hoping to prompt the master into a discussion, Anton said "Master, I have heard that objects are a very good thing - is this true?" Qc Na looked pityingly at his student and replied, "Foolish pupil - objects are merely a poor man's closures."

Chastised, Anton took his leave from his master and returned to his cell, intent on studying closures. He carefully read the entire "Lambda: The Ultimate..." series of papers and its cousins, and implemented a small Scheme interpreter with a closure-based object system. He learned much, and looked forward to informing his master of his progress.

On his next walk with Qc Na, Anton attempted to impress his master by saying "Master, I have diligently studied the matter, and now understand that objects are truly a poor man's closures." Qc Na responded by hitting Anton with his stick, saying "When will you learn? Closures are a poor man's object." At that moment, Anton became enlightened.

On reflection (and being a bit in two minds about this), I feel that the decision to disclose the sensitive information about the red-meat study is the right one. Academic integrity demands reproducible results; academic freedom allows us to research and disclose without fear or prejudice. Both principles are served by the full disclosure of data.

Anonymity of data is an exception governed by very specific rules -- the use of proprietary data in research, for example; or voluntarily disclosed data governed by the rules of research ethics (e.g. patient data). Neither of these apply to the red-meat study.

Academia exists to discover and disseminate. Exceptions to this should be rare (please, no puns...)

My post on today's activities at the Karaganda State Technical University in Kazakhstan.
Today was down to business with our hosts at the Karaganda State Technical University. Although we came prepared to give lectures, it turns out that the other main reason for our invitation was to explore collaboration opportunities. Most of the day was spent in meetings with professors, ...

A thought-provoking piece on how the rise of MOOCs will encourage universities to focus more on the dissemination of practical knowledge.
