The Battle Of The Sexes

By , 17 December 2014

Once upon a time eggs and sperm where the same size. Or more correctly, once upon a time there were no eggs and no sperm. Just gametes. Equal in size and equal in cost these gametes could reproduce with each other in a happy and fair trade.

Then one day an individual chanced upon a mutation that would change the world forever. His small, undersized gametes gave him a reproductive advantage, allowing him to have more offspring at a lower cost. He was the first male.

His family flourished with the advantage of cheap sex and further mutations drove his gametes smaller and smaller - until one day something unexpected happened: His family could no longer reproduce successfully. Their gametes were too small to create viable offspring.

Meanwhile, on the other side of the pond lived another individual who acquired a mutation that led to large gametes. Costly and burdensome her large gametes were a reproductive disadvantage. Her family was small and struggling. She was the first female.

List of 10,000 Famous People for PAO

9 December 2014

Recently I've taken up mnemotechnics which I've been using for music and lucid dreaming. One useful mnemonic tools is called PAO or Person-Action-Object. This tool encodes numbers into memorable unique scenarios. For example I have mapped the number 6 to 'Jesus walking on water'. You can then recombine these sequences the encode longer numbers.

If you don't know exactly how PAO works you probably want to read the Art Of Memory wiki first.

Yan from mentathlete.com generously posted a list of 10,000 famous people to use for your PAO system. I've forked his list and resorted it by <First Initial, Last Initial> to make it easier to find people for two digit numbers. I'm planning on updating and maintaining this list and will keep this page updated with the latest version.

Efficient Market or Predictable Patterns?

By , 25 November 2014

I'm doing Yale's "Financial Markets" course on Coursera at the moment and for one of the assignments we had to review a paper by Eugene Fama defending his theory of efficient markets. It was kind of interesting, so I wanted to post my summary here for you guys...

In "Market efficiency, long-term returns, and behavioral finance", Eugene Fama reports that anomalies which appear to contradict the Efficient Market Hypothesis are in fact predicted by the hypothesis itself. The hypothesis is therefore not falsified by the observation of these anomalies.

Fama discusses several patterns that have been published and seem to reflect an inefficient market:

  • Past winners tend to be future losers and visa versa (DeBondt and Thaler, 1985)
  • Long term returns are poor on IPOs and seasoned equity offerings (Ritter, 1991; Lougran and Ritter, 1995)
  • Stocks with high returns over the past year tend to have high returns over the following three to six months (Jagadeesh and Titman, 1993)
  • Divesting firms post above-average returns
  • Firms doing a stock-split post above-average returns.

Opportunity Only Knocks Once

By , 1 November 2014

I had been running up and down a flight of 500 stairs for half an hour listening to music on my phone. As a result, my shirt was drenched in sweat and clung to my chest as I jogged along the wharf on my way home.

When I first saw her she took my breath away. She was walking towards me, alone, dressed beautifully and ... well I've never seen breasts quite like that before. I didn't look at her directly as we got closer, but I could see her eyes shift from my face to my body and a shy smile forming on her face.

She was checking me out.

Possibly the most beautiful woman I have ever seen was checking me out.

So I ran straight past.

My brain was screaming at me to stop.

But I didn't.

The next evening I went back to the place I had seen her and waited. Just maybe it was her regular route home. There was no sign of her. She was gone.

Gone.

Gone.

Gone.

Progressing from the open string exercises, here is my transcription of Alison's first finger exercises for violin written in Sam's Mobile Music Notation. First, her tutorial:

And my transcription of the exercises (G3=1) with the images I use to remember the music.

Sam's Mobile Music Notation

By , 4 October 2014

This is how I write down music so I can read it from my phone or notepad or scrap of paper or whatever. I really really don't like traditional notation because it uses absolute pitches which makes everything very complicated.

Okay, so here are the basics:

  • beats are represented by spaces
  • bars are represented by a colon :
  • pitches are represented by scale degree number
  • chords are also represented by number
  • held notes are represented by ~
  • rests are represented by 0
  • downstrums are \
  • upstrums are /

Alison Sparrow's Violin Exercises - Open Strings

By , 4 October 2014

I've started learning the violin. It's something I always told myself I'd do 'later' (which is a pretty bad way to learn something new). So yeh... I just went to the shop, bought the stupid thing and started.

I found a good set of violin tutorials by Alison Sparrow on YouTube and have written down the first set of drills for you from tutorial 5 (I just prefer my notation to sheet music). There are six exercises and I use an image to remember each one as you'll see below. Firstly, here is the original tutorial:

How To Calculate Your ROI The Easy Way

By , 3 June 2014

Most people don't know if they're making money on their investments. We rely on heuristics, like "I sold it for twice what I bought it" or "The fund reported a 13% return this year". Neither of these statements give you a real answer to how hard your money is working for you. The first completely ignores how long you were invested and the second uses an arbitrary time span which has nothing to do with the amount and timing of YOUR investment.

We don't calculate return on investment because the math gives us a headache. Here's why. This is the conventional formula for calculating Return on Investment that you learn in high school or from some spammy website:

  ROI = profit / amount invested / time

It's not that the formula is incorrect (although the simple version above doesn't take into account any compounding over time), it is that the formula just doesn't represent the real world. We usually don't just invest a lump sum then cash out after x number of years. Most investments involve continuous give and take. We invest a bit, then some more, maybe we sell down or take dividends (or reinvest them) or spend money on capital improvements - and we do this at all sorts of random time intervals.

How To Ignore Hot Chicks

By , 5 May 2014

It is difficult to recall a single approach I have done recently that hasn't been followed by an instant date, day two, number-close or (god forbid) a facebook-close. So what is the problem with that? Well for me, there are two.

Firstly, I'm trying to work. Dating is huge time sink and distraction for me because it triggers my creative mode that leaves me day-dreaming about dating even when I'm not actually on a date. Although I can get away without working for long periods of time, I actually love my work and it gives me a big sense of satisfaction.

Secondly, there aren't enough hours in the week to meet, date and close all of those girls you see on the street. Opening is fun and rewarding and a phone full of messages from cute chicks is very validating but not ultimately what you want. What you really want is to be the man she gives herself to and craves sexually. Or to put it another way, you want to spend the whole week fucking each other, leaving the house only to stock up on food, drink and contraceptives.

So here is what I am doing to get a hold of this problem.
