Snorkelling at Perth    Posted:


I was in Perth for linux.conf.au 2014 and for a place that I've heard sucks, I'm mostly seeing the opposite.

Like Dirk Hohndel's talk, this post is not so much about technology as it is about the sea. I meant to write this post before I had even left Perth but I ended up getting sidetracked by LCA and general horseplay.

After Kate Chapman's enjoyable keynote I decided to blow that popsicle stand and snorkel at Cottesloe Reef (pdf) which is a FHPA (Fish Habitat Protection Area) just 30 minutes from the conference venue by bus.

TLDR: Getting a SSL Certificate Fingerprint in Python    Posted:


For a project I am working on I need to know the SHA1 hash (the fingerprint) of a DER encoded (binary) certificate file. I found it strange that nobody had offered up a here's a hunk of code for something so simple. Any novice programmer would probably eventually arrive at this solution on their own but for the sake of those Googling, here it is.

The Mark of Un-Authenticity    Posted:


With 3D objects getting increasingly easy to scan and print, and print quality increasing, I think accusations of counterfeiting and unlicensed production are going to start coming thick and fast. Should we start marking 3D printed objects clearly as non-original, different, alternative, un-official to help defend against these claims?

An "Unofficial" mark.

linux.conf.au 2014 - I'm Going    Posted:


Last week (or there-abouts) I registered for linux.conf.au 2014, booked flights and accommodation and then gave away literally all my savings to pay for it all. The conference itself is cheap, it's all the extra things that really cost money.

I have a feeling I will particularly enjoy LCA2014 because I'm keen to chase down some people who have some similar interests. Python, private email and federated social networking are on my agenda. I will also get my act together and take part in the keysigning (which I assume will happen) because it's been shown that building a web of trust is now more important than ever.

There are probably some other things I will do in Perth while I am there. Hopefully I can get some savings together and do the extra little things that make the trip worth it.

Anonymous Authentication With Public Key Cryptography    Posted:


I was looking at BrowserID which is an awesome decentralised authentication system that allows anybody with an email address to authenticate with a single identity. However, what if you don't want the service you are authenticating with to know your email address? What if you want several "single identities"? What if you want to be anonymous?

I've come up with a system which should help separate your personal identity from the account & data.
