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.

Fabulous pass !!!

Clear enough to see it all the way ... wonderful to see it again.

OK, so I succumbed and marked all the words before committing. Just as well, as there were several traps, but I ended up with this:

Choosing what to leave out is always so difficult.

It's always useful to find out what other writers and artists think about their work. This, from Rosemary Sutcliff:

"The temptation is to try & use everything you’ve found out in…research. That can be fatal, because you…only need to use about 1/10. It’s…like an iceberg…It has to be there, because it gives you the freedom of the period. But you don’t use it.”

It has some relevance to my planning of embroidery projects, especially the #OpusAnglicanum. I need to know something about it, but I'm not trying to do a period-accurate one, so I have to be a bit careful about what I include of what I know.

Something I don't get about 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.

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.
