Fulltime freelance provider of outreach and enhancement in maths ... I talk a lot. About maths.

I talk about other stuff too, like ballroom dancing, juggling, unicycling, education, engineering, software, and "other things".

But mostly about maths.

I tend to follow back, but only if you have something in your profile.

Something I don't get about #eduroam is that I'm typing my own password into a wireless access point controlled by another university.
Is it just inertia that has prevented it from moving to a web-based SSO process where I log in to my own university's website, and they pass a signed token on to the institution I'm connecting to eduroam from?

@christianp I had a problem with EduRoam when I was in Canada several years ago. Each institution kept passing the blame to the other, so with the timezone difference, each email took 12 hours to get a response, which was always ... "Ask them".

I had an off-the-record conversation with one of the parties who said: Having to get buy-in from the computer science departments of multiple universities, it's a miracle it exists, let alone occasionally works.

I wonder if interested people should just implement a parallel system that actually works and is competently designed.

@christianp I'll be interested to see the responses from people who actually know about these things.

I'll chart this later.

Holding fire to see whether or not a trailing "s" was needed ... that did the trick here.

Despite the efforts of my children and the Tyne and Wear Metro system (84% of trains on time last month!), I managed to catch the train to Durham I was aiming for, with three minutes to spare.

Often, when I am reading a good book, I stop and thank my teacher. That is, I used to, until she changed her number.

Woo Hoo !!!

There were some tricky bits in this one, but again, a little bit of lookahead did the trick.

Happy with this.

@ngons Absolutely. As with all these things, some are harder than others, and sometimes you're just lucky.

I like this game.
