• Bike maintenance.

Specifically, I failed to repair a rip near the valve stem of my inner tube. I thought I'd managed to patch it, but next time I tried to use my bike the tire had deflated again. So I got a replacement inner tube, and after putting it on the rear wheel yesterday I made a complete mess of attempting to put the wheel back on the bike. I attached the derailleur in the wrong place, and needed my friend to point out what I'd done. Then I twisted the chain, and when I couldn't work out how that had happened I gave up and untwisted it using a method that I was pretty sure was not the reverse of how it became twisted. That was stupid; eventually I had to re-twist and re-untwist it. Then I discovered I'd stripped a bolt, so I've got a replacement and I'll be trying again later today.

• Grade estimation.

I had expected my final year project to receive < 60%. I got 70% for it. I don't feel like I deserve it. I had also expected to get more than 70% for General relativity, although I didn't feel like I deserved it (I thought the exam had gone pretty well, but I don't grok GR); I actually got 61%. My other six modules were within expected bounds. My overall mark was high enough to be moderately surprising according to my priors, but not conditioning on my project and GR.

(At my university, >=70% is a first-class mark, which is an unusually good result; [60%, 70%) is a 2:1, which is a good result; [40%, 50%) and [50%, 60%) are a third and a 2:2 respectively, which are honours results but are not good. I don't know how universal this system is.)

• Job applications.

I've only sent off one recently; I then discovered that there are no H1B visas left for the year, so I can't get a job in Silicon Valley until next october at the earliest. I haven't sent any others off since, although I do have three places in Europe I'm planning to apply for.
