Greater Toronto Area BSD Users' Group


GTABUG is an assortment of IT hobbyists and professionals in the Greater Toronto Area who enjoy the BSD family of computer operating systems. We've been meeting since 1999, and we're very informal.


Invited: Anybody who's interested in BSD and/or the open-source software community. No previous IT knowledge or experience is required, but is certainly welcome.

Where: Olympic 76 Pizza Cafe at 8 Gloucester Street, Toronto. We're usually in the back corner of the restaurant.

When: Third Wednesday of every month. We meet around 19:00 (7:00 PM), although some hungry people will typically arrive closer to 18:00 (6:00 PM). Want our iCalendar file?

Topics: Anything. We socialize, discuss technical issues, share stories, solicit jobs, use our brainpower in silly ways, and sometimes we even talk about BSD.

Cost: Including tax and tip, each 10% slice of a 40.64cm-diameter "spicy special" vegetarian pizza costs $4.25, and each 591mL glass of draught beer costs $8.65. Other food and beverage options are available too.

BSD Introduction

BSD (Berkeley Software Distribution) was a computer operating system that was forked in 1977 from UNIX, which began development in 1969. BSD evolved into 386BSD, and today, BSD has four main open-source descendants under active development:

The BSD family's source code has undergone decades of public scrutiny, testing, and refinements by governments, businesses, acadamia, non-profits, enthusiasts, and others. All this work has enabled BSD's source code to become some of the most clean, secure, reliable, efficient, portable, and powerful available. BSD licences are very permissive, which makes it much easier to incorporate BSD source code into other projects.

A few examples of projects that have benefited from using BSD source code in part or in whole:

BSD is used quite extensively by the vast majority of modern computers and IT services, but it's ingrained so deeply that most people use it unknowingly. For example, the device you used to access this website probably uses the BSD TCP/IP stack. If you've ever watched Netflix, then you've used a service that's powered by a BSD operating system.
