Interesting post here summarising Credit Suisse’s Global Wealth Report. Basically to be in the top 1% of the global wealthy, you need to have $712,000 USD in net assets. To be in the top 10%, you need to have over $82,000 in net assets.
One percent of 7 billion is 70 million. So basically there are 70 million people in the world with $712,000 USD or more in net assets.
[EDIT] Actually, having just read the report, the results are expressed in terms of the global population of adults, 4.5 billion in 2011.
There’s an interesting article over at Stanford Magazine about a new technique for reducing muscle fatigue in athletes. Apparently by rapidly cooling an athlete’s hand, the athlete can train much harder as the muscles don’t get as tired during repetitive exercise.
Time-boxing is an idea that I heard about a number of years ago. It’s only been fairly recently that I have tried to incorporate it as a regular part of my daily workflow. The general idea behind time-boxing is that you concentrate on working for a set periods of time through-out the day. I adjust the period of time to how motivated I feel. When I feel really motivated I work in blocks of 25 minutes. When I am just getting started on the day I work in blocks of 10-15 minutes.
I keep my finances in J Wiegley’s Ledger format, which means everything is in a flat text file, for easy editing. I recently decided to use Xero.com for both my company and personal accounts. Unfortunately, this means that I somehow needed to upload all my past transaction data. So I wrote a Python script to convert Ledger format account files to OFX. You can grab a copy of the source code over at GitHub.
I’ve just started using Evernote to make a note of things I find interesting on the web and to capture ideas or random thoughts. So far I love it!
What I wanted was an easy way to extract the notes and save them to my filesystem, where they become much more useful. Specifically I want to save the notes as text files to a place in my Dropbox repository, so they get synced across all my devices, and are backed up.
There’s a great article here on estimating correlations and means when you have missing data in your datasets. It uses the Expectation Maximisation algorithm to calculate the missing values, and what is interesting is how much the implied correlation changes after applying EM.
I just brought Maplin’s USB Digital Microsoft with 400x magnification, which is advertised as having Windows-only drivers. System Profiler identified the chipset as being from Vimicro Corporation. I went to the Driver Download section of their website and downloaded (and installed) the DRV_ZC0301PLus_070305 driver. I then opened up Photo Booth, and was able to select the Vimicro camera as the video source. What I should have done was just try and access the Microscope using Photo Booth before I installed the driver, as I half suspect that there was no actual need to install that driver.
Please try to use the microscope with Photo Booth first before downloading the driver, and let me know in the comments if that works.
