Timelies all!

Yay, Jilli!

We've got a big trip coming up in August. Worldcon is in London this year, so we decided to extend our trip a bit. We'll be in London for a couple of days after the con, then we head to Dublin for a couple days. Never been to Dublin, so that should be fun. (Yeah, we went to London last summer, but there are plenty of things we still want to see. Plus, we don't have to worry about my folks keeping up with us this time.)

I am waiting for Big Work News, and it is killing me! I'd better hear tonight.

Yay, billy! Have an echidna.

Don't mind if I do! [link]

Jilli! I’m so happy for you. I know how stressful this has been. Hurray!

Have fun in Ecuador, fellow travelers! I spent my first day in Northern Ireland today. It’s gorgeous; really reminds me of rural Connecticut in many ways. ND gets in tomorrow morning, and we have all kinds of fun planned with the family. I was doing well powering through the 8-hour time shift after flying in this morning until I lay down this afternoon “just for a quick nap” and woke up at 9. Oops. But I think I’m tired enough that I should fall asleep again pretty soon and wake up at a decent hour tomorrow, so my hope is that that will be the extent of my jet lag. It’s just shy of midnight here right now.

level 20 of the Euclid game

I had smooth sailing until level 19. Now I shall have to puzzle a bit.

Is 20 the last level, or are there more?

20 is the last level. I got the solution, but I'm still not sure why it worked. I was able to work out the beginning of the solution by myself, but then after that, I tried a few things that seemed logical but didn't work, and then just started trying things, and one of them ended up working.

I need to figure out where to go on vacation. Someplace rural and quiet.

Vermont! Beer and cheese.

My travels are much less exciting. I got back from Columbus late last night and am going back for another week starting Monday.

20 is the last level. I got the solution, but I'm still not sure why it worked.

For my solution, I basically had to puzzle out two steps: first, how to find the point of intersection between the tangent line and the line through the two circles' centres; and then how to construct a line passing through a given point and tangent to a given circle. That second part stumped me until I remembered a result about right-angled triangles from Geometry of the Circle in Year 9 (which I mostly remember as being immensely fun and taught out of an atrociously formatted textbook).

What approach did you take to get it?

I was able to find the point of intersection between the tangent line and the line through the circles' centers pretty quickly, but then figuring out how to construct the tangent line was where I was stumped. I don't totally remember the train of thought that eventually got me to the solution.
