A brilliant book dealing with several cognitive biases and our understanding of risk. Many interesting ideas are explored within and they raise even more questions. I think I’ll do a dedicated post on this later.

Baudolino By Umberto Eco

This book was a slight deviation from what I was expecting after Name of the Rose and Foucault’s Pendulum, but still fascinating in its own way. The plot is woven into various historical events in the Middle Ages. The novel has an interesting point to make about the accuracy of historical texts and the authenticity of artifacts and relics. That is, people who “recorded” history may have not written down what really happened but altered it to manipulate the opinions of future historians.

Fatal Misconception: The Struggle to Control World Population By Matthew Connelly

The intricate history of the population control movement. This is a well written, comprehensive book on the subject. Although the author has a bias, and declares so himself, I felt he did a great job in presenting the facts and events objectively. The history of this movement reads like a soap opera at times, with interest groups, NGOs, the church, and governments all vying for control and influence. While I don’t necessarily agree with some of the author’s conclusions, I do think it is very important to note, in the authors own words: The only factor that has consistently and convincingly been found to correlate with lower fertility is increasing women’s education.

The Fortune Tellers: Inside Wall Street’s Game of Money, Media and Manipulation By Howard Kurtz

An interesting, though dated, book which outlines why you should not trust any analyst you see on TV or any of the personalities appearing on financial channels such as CNBC. While historically interesting I would not characterize this as essential reading, although its central arguments remain true today.

The Last River: The Tragic Race for Shangri-la By Todd Balf

Unfortunately I did not get to see Solo at the International Documentary Film Festival Amsterdam but I’m sure it would have been a good companion to this book, which documents the tragic 1998 kayaking expedition to the Yarlung Tsangpo gorge. One of the most remote places on Earth. It provides an interesting glimpse into the psyche of adventurers and practitioners of extreme sports.

The Arraignment By Steve Martini

A legal thriller / mystery novel. While entertaining, I wouldn’t recommend it.

I will not go into the details, except to say that phages are just viruses that infect specific bacteria. Similarly, the full history of phage therapy is long and interesting but beyond the scope of this post.

Back in 1997 the BBC program Horizon (episode “The Virus that Cures”) introduced many people to phage and sparked much interest in the West. So here we are 11 years later and it seems that very little has happened. So where did things go wrong?

First it must be realized that a phage is VERY specific in which bacteria strain it targets. This property is very useful medically but very problematic for companies looking to deploy phage based treatments. The specificity leads to two possible types of treatment:

1. The first would be a highly personalized approach where the particular strain affecting a patient is determined and a phage collection is checked to see if there is an existing phage which targets that particular bacteria. If the matching phage is not in the existing collection, a new lytic phage must be found, although this could take quite some time.
2. The second option is to just create a cocktail of different types of phages for common bacteria, and hope you get lucky. This would probably be very effective for a majority of cases. Of course if your cocktail is ineffective, you would have to go to the personalized approach.

Now it important to note that it is very difficult to get the FDA to approve a cocktail. In the domain of personalized treatments, it is not exactly clear how a company would have to get approval from the FDA (which takes about 12 years on average) if they wanted to treat a single person with a brand new phage. Add to this that fact that single biophages can not be patented and you get a perfect regulatory storm.

My research seems to indicate that several pharmaceutical companies which have tried to test the FDA waters (Targanta Therapeutics [formerly PhageTech] and Exponential Biotherapies) have met with little success. Although the FDA has allowed the use of phages on meat products in the food industry to prevent food poisoning.

So from an investor’s perspective the best policy seems to be just sitting back and waiting for some big changes in FDA regulation. In the mean time it would be a good idea to keep an eye on developments outside the US, particularly on countries with much more relaxed regulation. Depending on the exact change in regulation which will come inevitably, a company’s large collection of phages may go from being just scientifically priceless to a valuable capital asset as well. Of course this change in policy may only come about once the antibiotic resistance situation is way out of control. Until then, the bacteria will divide as they always do and the FDA will sleep as it always does.

Here are the companies I looked at:

• BioControl Ltd. (UK) http://www.biocontrol-ltd.com

• Biophage, Inc. (Canada) http://www.biophagepharma.net/index.html

• Eliava Foundation (Georgia) http://www.eliava-institute.org

• Gangagen (India) http://www.gangagen.com

• Intralytix, Inc. (USA) http://www.intralytix.com

• Lucigen Corp. (USA) http://www.lucigen.com

• Neurophage Ltd. (USA) http://www.neurophage.com

• Novolytics Limited (UK) http://www.novolytics.co.uk

• Phage Biotech, Ltd. (Israel) http://www.phage-biotech.com

• Special Phage Services Pty Ltd (Australia) http://www.specialphageservices.com.au

Here is a quick guide to help you through the procedure. It will assume you are starting on a brand new laptop with Vista pre-installed. If this is not a new laptop then backup, backup, backup.

1. Remove all the useless bloatware which Sony has installed.
2. Create recovery DVDs. Sony does not provide any recovery disks so you should make some in case….
3. Use the Start Menu > Computer > Manage > Disk Management to “Shrink Volume” of the main system partition. Note that Sony will have a 9 Gb EISA recovery partition at the start of the drive (I would recommend leaving this alone).
4. Yes, the Shrink Volume feature will only let you shrink it to about half, if you want to get by this then disable system restore, the pagefile, and hibernaion. With these disabled you can shrink the Vista partition to 48 Gb after defragmenting the drive. This allowed me to have the following partition setup on a 250 Gb drive:
   1. 9 Gb EISA recovery partition
   2. 48 Gb Vista partition
   3. 30 Gb FAT32 partition to share data between Windows and Ubuntu (created using Visa)
   4. 140 Gb Ext3 Linux partition (created by Ubuntu installer)
   5. 6 Gb Linux SWAP space (created by Ubuntu installer)
5. If you want to be able to read your Linux data from Vista have a look at http://www.fs-driver.org/ or http://sourceforge.net/projects/ext2fsd
6. Download the Ubuntu ISO for 64bit AMD and Intel computers from http://www.ubuntu.com/getubuntu/download
7. Although you could burn it to a CD to install it, I would recomend using a USB key:
8. Download UNetbootin from http://unetbootin.sourceforge.net/
9. Get a USB key that is at least 1 Gb and backup the data on it.
10. Run UNetbootin, point it to the Ubuntu ISO you just downloaded, and select the location of the USB key.
11. Once UNetbootin has created the bootable USB key reboot the computer.
12. Ubuntu will go into live CD mode.
13. Select Install and follow the instructions.
14. Selecting the manual partition choice will allow you to create the 140 Gb Ext3 partition which will be mounted as root and the 6 Gb Linux Swap partition (double the RAM size).
15. If all goes well you will see the Grub menu upon restart. Select the first choice.
16. The Grub menu will have two identical choices listed at the bottom. The second to last choice is pointing to the VAIO recovery partition. This confusion can be cleared up by changing the Grub menu using “su gedit /boot/grub/menu.lst”
17. Go down until you see:
    

    title Windows Vista/Longhorn (loader)

    root (hd0,0)

18. Change the title to “VAIO Recovery Center EISA Partition” to clear up any confusion.

Next we come to Sony VAIO specific problems in Hardy Heron (Ubuntu 8.04):

1. The backlight is stuck at full intensity.
2. Download the xbacklight package using the System > Administration > Synaptic Packag Manager
3. Write a small script which has the following two lines:
   

   xrandr –output LVDS –set BACKLIGHT_CONTROL native

   xbacklight -set 50

   where 50 is the percentage intensity.

4. Headphones dont work without some modifications. Add the folowing line at the end of the file /etc/modprobe.d/alsa-base
   

   options snd-hda-intel model=vaio

5. To get mic working edit your /etc/init.d/alsa-utils as described here: http://ubuntuforums.org/showpost.php?p=4502727&postcount=4
6. Switch to the internal mic then enable Capture in the volume control panel and set your mic recording level as explained here: http://ubuntufs.wordpress.com/2006/06/08/trouble-with-your-microphone/
7. Get your Motion Eye Webcam working by following the steps outlined at this site: http://www.palmix.org/r5u870-en.html

Enjoy Ubuntu!

This book has come with very high recommendations from several people I’ve met while travelling. Earlier this year I heard that a big-budget movie was being developed based on the book and knowing Hollywood’s terrible track record for movie adaptations, I definitely wanted to read the book before any movie came out. While short at under 180 pages, the book certainly lived up to its expectations. The plot centers around the journey of a boy as he journeys in search of a treasure in Egypt. Along the way he meets many interesting characters and learns some important lessons about life. An excellent read, highly recommended.

The Future of an Illusion By Sigmund Freud (1927) (http://en.wikipedia.org/wiki/The_Future_of_an_Illusion)

James Strachey 1961 Translation

An excellent essay by Freud on the nature of religion and why it is needed (for now) to ensure the survival of civilization. Although this was written in German originally, even in English the ideas presented are integrated into a beautiful smooth structural flow. Freud is able to predict many of the criticisms the reader may develop and address them. Perhaps Freud’s biggest strength is his ability to logically take on subjects which to this day are somewhat taboo in society (eg. People’s fear of death).

Slipping into Paradise: Why I Live in New Zealand By Jeffrey Moussaieff Masson

An interesting book comparing life and society in New Zealand with the rest of the world.

A Shortcut Through Time: The Path to the Quantum Computer By George Johnson

A generalized introduction to quantum computers, the problems where they would succeed over classical computers, and some of the algorithms developed for these problems.

Hacking Matter: Levitating Chairs, Quantum Mirages, and the Infinite Weirdness of Programmable Atoms By Wil Mccarthy

Perhaps a bit old now, this book gives an overview of the research being done towards the goal of creating a type of programmable matter which would allow us to fully control a variety of properties normally in the hands of nature.

• gds2pov (http://atchoo.org/gds2pov/)
• POV-Ray (http://www.povray.org/)
• KLayout (optional) (http://www.klayout.de)
• LayoutEditor (optional) (http://layout.sourceforge.net)

First, begin by exporting your model in GDSII format. I have found that for best results the exported GDSII model should be a single cell (flatten the hierarchy if necessary). Both KLayout and LayoutEditor can be used to view the GDSII file, which will look something like this:

Next the process file used to fabricate the device must be written. Each layer is described in a similar fashion:

LayerStart: POLY0 (layer name)
Layer: 13 (the layer number in the GDSII file)
Height: 2000 (uses the same units as the GDSII file; starting height of the layer)
Thickness: 5000
Red: 1
Green: 0.9
Blue: 0.75
Filter: 0
Metal: 0
Show: 1
LayerEnd

Once you have written your process file, run gds2pov from the command line:

> gds2pov -i model.gds -o model.pov -p process.txt

This will generate a .pov file for your model. Open this using POV-Ray and set the render image size under the “Render > Edit Settings” menu. Finally, set your camera angles in the pov file:

camera {
location <188,257,-279>
sky <0,0,-1>
look_at <8,27,0>
}

The camera angles may need some adjustments based on your particular model. Running the script will render the model as seen from the camera angle chosen. This is the final rendering of the layout shown above:

Enjoy!

Adventure Capitalist by Jim Rogers (http://www.jimrogers.com)

Good book chronicling one of the world’s longest road-trips by famed investor Jim Rogers at the turn of the millennium. While overall a great read, some countries are only briefly mentioned and he could have added more discussion on the various predictions and conclusions he makes as a result of the trip including:

• The new commodity bull market has started.
• The twenty-first century will belong to China.
• There is a dramatic shortage of women developing in Asia.
• Pakistan is on the verge of disintegrating.
• India, like many other large nations, will break into several countries.
• The Euro is doomed to fail.
• There are fortunes to be made in Angola.
• Nongovernmental organizations (NGOs) are a scam.
• Bolivia is a comer after decades of instability, thanks to gigantic amounts of natural gas.

Tai-Pan by James Clavell

A true classic which is hard to put down once started. A fascinating look at the opium trade, founding of Hong Kong, and international relations with China in the 1800s all wrapped around an excellent plot. It also got me looking at the history of Malaria (http://www.malariasite.com/MALARIA/History.htm).

Freakonomics by Steven D. Levitt and Stephen J. Dubner (http://freakonomics.blogs.nytimes.com)

I first heard about this when Prof. Steven Levitt went on the Daily Show to discuss some of his interesting findings. Simply put, when given access to rare types of datasets an economist can come up with many interesting insights into the world.

White Gold: The Extraordinary Story of Thomas Pellow by Giles Milton

In early April there was an article titled “Freedom of the Cyber Seas” over at CSO Online (http://www.csoonline.com/article/print/329164) which compared piracy on the high seas in the late 18th century with the current security problems on the internet. This book provides further insight into how the European powers attempted to deal with the Barbary states and centers around the story of Thomas Pellow who was captured on the high seas and served Sultan Moulay Ismail for over 20 years.

Ambassador without Credentials by Sergei Snegov

Written in 1977 by Soviet SF author Sergei Snegov, this is a collection of 12 short stories exploring various ideas being researched by two brilliant brothers as they attempt to solve various mysteries. One of the stories lays out the same fundamental ideas explored in Michael Crichton’s Sphere over 10 years later.

Heart of Darkness by Joseph Conrad

The inspiration for the film Apocalypse Now, follows a journey up a river in the Congo to an ivory trading station. Complex, dark, psychological, it succeeds in putting the reader into the same state of mind Conrad must have experienced in his own journey up the Congo River in 1890.

Coalescent by Stephen Baxter

Average SF book exploring the possibility of humans using a hive type social structure as seen in beehives or ant colonies.

Tales from the White Heart by Sir Arthur C. Clark

A great collection of short stories centered around discussions at a small London bar in the 1950s.

Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps, and the 10th Dimension by Michio Kaku (http://www.mkaku.org)

An excllent look at the historical development and implications of theories based on a multidimensional universe.

The Fourth Protocol by Frederick Forsyth

Good thriller centered around a plot by the Soviets to destabilize the UK government.

Hunting Al Qaeda by Anonymous

An account of the time spent in Afghanistan by a special forces unit of the US National Guard which tends to focus on the bureaucratic nightmare they encountered.

Chasing Shakespeares by Sarah Smith

A fictional book about two scholars investigating the Shakespeare authorship question in London. (http://en.wikipedia.org/wiki/Shakespeare_authorship_question)

The Trudeau Vector by Juris Jurjevics

A good thriller about an epidemiologist sent to determine the vector for a pathogen which is killing researchers at a remote Arctic station.

The Camel Club by David Baldacci

A decent thriller about a high-level conspiracy in Washington.

The Broker by John Grisham

Another decent thriller about a Washington lawyer being chased by various intelligence services.
