Flashmob daily scrum

I think our team is too big to hold a daily scrum meeting, so I turned to a couple of people near me on Wednesday and asked "What did you do yesterday? What are you doing today? What's holding you up?"
I answered as well.
The next day, I did the same again with a different group of people, announcing "Flash-mob scrum" as we started.
Today I rounded up a couple of people from previous days and we "flash-mob scrummed " by two new people. I'm hoping it might just work.
This was done in a spirit of TCC, larking about, but based on previous practice, which is vital for TCC. The team seem to be talking to each other bit more too. 

TCC - the precursor to TDD

TCC - the precursor to TDD

I gave a (very short) lightning talk at #ACCU2012 about TDD - test driven deletion.
In a zombie state when I got back from the conference the telly was doing a retrospective on Tommy Cooper.

I reckon, before we do TDD, we should look at TCC (Tommy Cooper coding), but with the safety of high test coverage, maybe of the requirements rather than any exisiting code, which we are clearly going to delete. I will expand on the ideas here, and hopefully manage to buy suitable props to demonstrate this as a talk one day.

Mocking in C++

ACCU London's July 2011 talk was about mocking in C++, given by Ed Sykes and hosted by 7 City.

Ed talked about MockItNow and Hippomocks. He pointed out, as has been said many times before Mocks aren't Stubs.

I can no longer remember all the details so will have to try these out for myself to see how they work.

Many thanks to Ed for a great talk, though.

Power series for PCA

The book says estimate the value of the eigenvector, then iterate.
But my vector cycled as transpose(1,1), transpose(-1, 1), transpose(1, 1) which is a bit of a problem.
Oh for precise instructions.
I'll report back when I find a suitable estimate for the starting value.
