The joys of Duckworth-Louis

At first sight, the scorecard is hard to believe. Scotland made 152 in 30 overs, and yet the target for the Windies was a “revised” 165.

Turns out it’s due to the Duckworth Louis system, as the match suffered from two rain delays and was twice reduced in the first innings, first to 42 overs, then to 30. It does make sense, though – if a team knows there are only 30 overs to bat, they’ll be more aggressive.

As it turns out, the Windies just about survived.

Darth Vader to read the Declaration of Independence

James Earl Jones, whose lent his voice to the unforgettable Darth Vader, will read the Declaration of Independence at the National Constitution Center in Philadelphia, USA (via).

If only we could hear a slightly modified version… “When in the course of human events, it becomes necessary to dissolve Rebel scum…”

The iPhone

From The Economist:

The danger in developing a gadget that tries to be a phone, internet appliance and iPod all in one is that it can fail to accomplish each as well as it might… simply making a phone call is more cumbersome than it should be, requiring up to half a dozen different steps.

I use my phone for maybe minutes a day, and I’d really like to keep it that way. No matter how gorgeous the screen may be, does anyone really want to spent more than half an hour a day staring at a 3.5 inch screen? 95% of the calls I make from my phone require two clicks (speed-dials). By now, I can type an SMS without even looking at my phone (I have a 3 year old Nokia 7250i by the way). No matter how innovative or great looking a phone is, I feel it’s important to get the basics right.

If you really think about it – the iPhone is sort of an “attention hungry” device. Because it has no keys a user must use the touchscreen to operate it. Here’s a test – can I write an SMS with just one hand? Can I at least make a call? How about change the volume of the currently playing song? I suspect the answer is “probably not”. An innovative new interface doesn’t mean the old ones aren’t useful. What do you think of someone who uses the mouse to go to Edit->Copy and Edit->Paste instead of pressing Ctrl/Cmd + C and Ctrl/Cmd + V?

For a convergence device which is supposed to do “everything” and run OS X, I really hope Apple does provide a real programming interface for the iPhone other than web apps. I cannot understand their point of view that third-party apps are a security concern (after all, Windows mobile phones have been around without serious security issues for years, is Apple saying OS X is more insecure?). Not only are they preventing serious users (who want things like SSH) from buying the iPhone, they’re also pretty much trying to cut out a large part of the mobile-phone software industry, which is no good thing given that it’s a market that Apple has just entered.

It is quite probable though, that second generations (and smaller version) iPhones are already in the design stage and hopefully they’ll address some of the issues around the first-gen iPhone. I would certainly love to see an iPhone with full-fleged Safari running on hardware that has some basic keys as well as the touchscreen interface.

Games Indians Play, by V. Raghunathan

Games Indians Play

A great book. The author clearly feels that the Indian national character has some fundamental problems – we are free-riders, seek to serve self over society, are way too intelligent for our own good. These traits lead to the phenomena which plague Indian society – things like corruption and it’s general acceptance, unhealthy levels of public hygiene and pollution, the pathetic state of core systems like education, and the tendency to pursue loopholes relentlessly even when they do no good in the long run. These points, while perhaps not representing the complete picture (India has improved a lot, in my opinion) are still very hard to argue against.

He explains this in terms of a game-theory concept called Prisoner’s Dilemma (PD), which is basically a story about how two people have a choice to either co-operate with each other or betray – and it turns out that the overall best case scenario happens to be when both cooperate, although it could be argued that it would seem more self-serving for each to betray. Of course, the link is that Indians tend to betray (society) to achieve personal gains – like throw garbage on the road for personal convenience, or cut queues where ever possible – but which lead to a non-optimal society and thus reduced benefit for all.

The example is used convincingly to address a lot of issues; however the author stops at making any scientific claims (he says in the prologue itself that his ideas are not exactly backed by scientific data but could be valid hypotheses for constructing tests). However, he does talk about studies done to solve PD, and explains that entirely self-serving strategies tend not to do too well.

A classic example that I can think of (though not mentioned in the book) is the use of “water pressure amplifiers” in some communities. As all Indians know, water can be a big problem in India and it’s common for the water pressure to be low during summer. So someone installs this device which, when inserted into the plumbing, amplifies the pressure into your house – at the expense, of course, of slightly decreased pressure to everyone else. Short-term gain for sure – but soon enough everyone’s heard about the device and every household has it’s own. The end result? Back to square one, since there is only so much water pressure available, and everyone is now drawing it equally. Oh, except that everyone has spent a certain amount of money buying the device, and everyone is continuously paying electricity bills for it. And of course, nobody will dare stop using it because if you’re the only one without an amplifier, you can forget about getting any water at all in your house!

In the last chapter, he explains how this modern version of game theory ties in perfectly with ideas conveyed in the Bhagvad Gita. The Gita encourages one to just abide by “dharma” (or right action) – and promises that this will achieve the “highest good” – which is presumably the highest good in terms of society and even the person in the long term. Given a problem like PD, it turns out the most optimal actions are in fact those that are taken in good faith, and not ones immediately self-serving even though plausible arguments can be constructed that one stands to gain more in the short-term by taking the “selfish” action.

A very readable, short book, not only with interesting discussion on game theory but also on the state of India – the work is full of examples of just how much Indians can be self-seeking while ignoring the greater good. At once poignant, humourous and fascinating.

Math and the Mona Lisa by Bülent Atalay

Math and the Mona Lisa

The water you touch in a river is the last of that which has passed and the first of which is coming. Thus it is with time present. Life, if well spent, is long.

– Leonardo da Vinci

Science books are a lot of fun, and this one was no exception though it’s a bit different. It’s themes are Leonardo’s life and the confluence between the fields of arts and science.

It talks about how artistic intuition happens to agree very well with certain numbers (particularly the golden ratio), across generations from the egyptian pyramids to paintings to the Petronas towers. There’s also a discussion of how revolutions in artistic and scientific thinking sometimes take place in tandem.

Throughout the book though, Leonardo’s approach to science, art and learning remains an inspiring background. The reader is treated to an amazing being who excels at whatever he lays his hands to, yet his curiosity and desire for improvement and knowledge lead him to ever greater things. A consumate artist who made only about a dozen paintings, all masterpieces, each way better than the last. An amazing scientist who thought up concepts and experiments that wouldn’t be rediscovered until centuries later, but didn’t bother to publish his findings.

There’s also a bit of standard science history over the last millennium which most avid science readers will be familiar with but it never gets boring. The author writes in a conversational style that is very appealing. I’ve read quite a few science books but the art angle in the book was very refreshing.

I picked up the book totally at random from the library – turned out to be a totally great read. It may be slightly heavy on the mind though, in case you don’t like art or science much!

Safari meets the Jungle

Mike Elgan has written a wonderful piece in MacWorld analyzing the appearance of Safari for Windows. From the article:

The insular Apple universe is a relatively gentle place, an Athenian utopia where Apple’s occasional missteps are forgiven, all partake of the many blessings of citizenship, and everyone feels like they’re part of an Apple-created golden age of lofty ideas and superior design.

But the Windows world isn’t like that. It’s a cold, unforgiving place where nothing is sacred, users turn like rabid wolves on any company that makes even the smallest error, and no prisoners are taken. Especially the Windows browser market.

This is no Athens. This is Sparta.

Eating carbon

The Economist explains that companies in America are being forced to go green because of the inevitability of carbon-trading systems: if they want to have a say in the carbon market, they need to be lobbying for emission controls. A quote that cracked me up:

As Mr Rogers explains: “There’s a saying in Washington: if you’re not at the table, you’re on the menu.”

And here’s another priceless jab from another article in the same survey:

There are lots of energy-efficiency regulations in place already, and they are being tightened. Incandescent light bulbs are the top target at the moment. Both the European Union and Australia said earlier this year that they are planning to ban them. But the man in the vanguard of this green revolution is Fidel Castro, who started phasing them out two years ago.

Heartburn

For the first time since removing “Computer” from their name, Apple Inc. has shown us they mean business, finally releasing MacBook Pros that make my mouth water. How sad is it that I can’t even think of affording one!

Santa-Rosa support has been offered by almost all other manufacturers for a while now, so it was about time that Apple announced it too. But increasing the baseline memory across all models to 2 GB is real sweet.

Even though there’s still no sign of a “real” portable Mac, the 15″ MacBook Pro now is thinner than the Macbook (only an inch thick) and at 2.45 kgs, only 0.14 kgs heavier than the Macbook. Does anyone still want just a Macbook? And it’s only a quarter of a kilo heavier than the 12-inch Powerbook G4 that I’m typing this on!

The upgrade to Nvidia 8600M cards will mean the MBP is now virtually as good a gaming machine as any gaming desktop. Especially since you can actually use Bootcamp to run Windows on this thing. And it probably becomes easier to dualboot it with Linux. Apple is one of the first to introduce LED-backlit screens, I’ll wait for the reviews to evaluate that. There’s a insane 1920×1200 optional screen for the 17″ model which should be good for people who edit photos and have expensive houses to mortgage.

This weekend, by which time the new models should be in Singapore, I will do what I usually do – head down to the Apple store and ogle at them. Now I know why wise people say you shouldn’t desire things too much. It’d sure make life a lot easier right now.

About the only thing I can complain about – besides not having a 13″ MBP model (which would probably compel me to go rob a bank somewhere) – is the lack of an option to upgrade the 15″ screen from 1440×900 to 1680×1050.

Go ogle!
