BBC producing film based on the fall of Lehman Brothers, due this Autumn.

The BBC said on Wednesday that it is producing “The Last Days of Lehman Brothers,” a TV movie “inspired by the real events” of that September weekend, for its BBC Two channel...It isn’t clear when “The Last Days,” written by the BBC scribe Craig Warner, will come out, other than sometime this fall.

Android and iPhone Apps Cost About The Same, Except For Games And Dictionaries #1

The effect of competition

Washington Post figures the Apple App Store is cheaper in some instances because competition between the huge amount of similar apps has driven prices down. The Android market has much less apps available that Apple offers. At this time, the Android Market has about 6000 apps compared to 65,000 on the App Store. #1

Carbon Emission Comparison: Eurostar vs. Indian Railways

Rail travel is always projected as being the more fuel efficient transport - when compared to air travel anyway.


So anyway, this Sunday evening, a bug caught me and I began to wonder: Is it more fuel efficient to travel by high speed trains that are modern in design and run in western countries, or if it is cheaper in face to travel by slow moving mass carriers, such as trains in India.

At the face of it, it seems slower mass transport is bound to not only be cheaper, but also more fuel efficient and thus more 'green'. But lets not hypothesise over it, lets get some actual numbers out.

According to the Eurostar website: The carbon emissions per passenger distance travelled for the London-Paris round trip are 11 grams per passenger kilometre.

So lets see: there are no exact figures calculated for Indian Railways - at least none I want to depend on, so let me calculate it myself. I got access to the Annual Statistical Statements 2006-07 which is the latest year for which stats are available.

So I focused on two classes of stats:
  1. Total passenger kilometres (col.13 on pg. 12 of pdf)
  2. Fuel consumed for passenger services (col.3 on pg.4 of pdf)
The reports may appear confusing if you're unfamiliar with Indian Railways. They're divided into several zones (it is in fact the fifth largest network in the world) and stats are computed for each zone separately and then weighted averages calculated.

Anyway - so here are the figures I managed to dig out.

Total Passenger Kilometres: 694 billion kilometres ('a') = 694,000 million km.
Total fuel consumed (equivalent in coal): 759,140 tonnes ('b') = 759.14 million kg.

Coal used per passenger kilometre in 2006-07: 1.09 grams
Indian Railways: 1.09 grams
Eurostar: 11 grams

So effectively, Indian Railways is 10 times more carbon-efficient than the Eurostar's most efficient journey.

--- But before you say 'yay' read this:

If you would believe the stats offered by the Indian Railways, it is in fact the safest rail network in the world with the lowest accidents per million km:
Japan Railway Group: 0.65
Germany: 0.91
France: 0.84
Italy: 0.73
Indian Railway: 0.55

Of course this doesn't take into account fatalities or fatalities in suburban rail networks: with 20,000 people dead in Mumbai in rail accidents between Jan 2003-Dec 2007.

Not surprising. Youtube is full of videos like this one.

What happens when Twitter and Facebook collapse simultaneously?

So, Twitter has been down for over half an hour now. They've acknowledged this on their status blog.


Many users (including me) are reporting problems with Facebook too.

Is this the apocalyptic scenario when the world's social media collapses?

Maybe this is a Denial of Service or hack attack? What are the implications if the world's personal information lands up in the hands of some hackers, or even worse, an authoritarian government. After all, is it just a coincidence that this happens one day after Ahmadijenad was sworn in as Iran's President?

Update @15:28 BST. Livejournal is now down as well.

London's best street food: Whitecross Street. [TimeOut]

This week's TimeOut has an article on London's best street food and Whitecross Street behind Cass is featured.

www.timeout.com/london/restaurants/features/8332/5.html

Whitecross St, EC1Y (www.whitecrossstreet.co.uk). Old St tube/rail or Barbican tube. Speciality food market 11am-5pm* Thur-Fri; some stalls operate on other weekdays as well.

* Be aware that although the official opening times are from 11am to 5pm, we’ve found that most of the stalls pack up and leave soon after the lunch rush is over and the hordes have returned to their offices. We’d recommend getting there by 2pm for the best and freshest grub.

Collective wisdom and information overload.

Something about ants from the oldest magazine in the U.S.

www.scientificamerican.com/article.cfm?id=mindless-collectives-rational-decision-making

...these findings “underscore a nonintuitive point—getting lots of information about a problem may not help decision making if you have only limited computational capacity to process it. You might do better with a strategically limited set of information. The trick, of course, is knowing what information to use and what to exclude.”
