      I do like Harold Lloyd better, but his ideas on #Copyright and protecting his films have landed him in obscurity compared to other artists who were more lenient (or lost their copyright due to interfering management)

      Never mind what happens when you try to distill your own alcohol - it's even illegal to own the equipment to do it!

      That's my point - try to buy alcohol somewhere else, and *armed guards* at the border will take it away and throw you in jail for bringing in more than what they figure will have a minimal impact on government revenue.

      That's because you live in #Ontario, where #alcohol sales are a government-controlled and -owned monopoly. Because alcohol sales are a revenue-generator for the government they set the price *way* above production costs. After all, how much could it possibly cost to let some potatoes ferment in a bucket?

Cryptography and Security Events in Kitchener-Waterloo

Posted by Bob Jonkman on October 9th, 2013

The months of October and November are shaping up to have some great lectures and presentations on cryptography, security and privacy.

Keysigning materials

Yesterday started off with an informal keysigning at the KWLUG meeting. The presentation was on the Scratch programming environment, nothing to do with GnuPG/PGP or cryptography. But a few of us exchanged little slips of paper with our key fingerprints, verified that the name with the fingerprint matched the person we knew, signed the keys, and so improved our standing in the Web of Trust. I hope that this becomes a regular part of all KWLUG meetings. The more people that participate, the more confident we can be about the validity of keys we may not have verified ourselves.

Today I attended the first UofW CSClub lecture on Security and Privacy by Sarah Harvey. If you’ve been following the news about the Snowden revelations you’ll know why security and privacy is important. The room was full of computer science, math and cryptography students, so the discussions were deep and technical.

There was a vacancy in the November KWLUG meeting so I asked Sarah if she would repeat her lecture. Let’s see what the KWLUG bosses have to say

There are more CSClub lectures scheduled, check the schedule on the CSClub site.

I’ve volunteered to do a presentation on Encrypting E-mail with GnuPG, Thunderbird and Enigmail, followed by a formal keysigning. I’m developing the presentation notes and keysigning procedure on the KWCrypto Interest Group Wiki that was set up after the Kwartzlab keysigning party last year. Please join me on the Wiki and the mailing list — I’d appreciate the help.

–Bob.
