McLaren road cars and carbon fibre

This is a brief and much abbreviated story of the McLaren road cars.
1998 - Scepticism about performance and safety:
McLaren was the first manufacturer to bring out a full carbon fibre monocoque chassis production car, the F1 in 1998. It, also used gold foil as heat reflector, titanium, kevlar and magnesium and unique McLaren F1 technology to a road car. It was a radical idea then. But success after success the McLaren F1 proved the sceptics wrong, by its performance/safety and became the fastest production car in 1998 (390 km/hr) and still remains the fastest naturally aspirated production car in the world. I think a true turning point in automotive history.
2009 - Scepticism about profitability:
Mercedes and BMW even after collaborating with McLaren in the past (mostly to produce its engine) did not fully pick up on the idea. BMW convinced itlself that experimentation in carbon fiber would never be cost effective to be profitable. I think BMW even made a public statement to that effect. There was a carbon fibre Mercedes Mclaren SLR though. BMW stuck to traditional manufacturing processes and played it safe.
Then again, McLaren stuck to its guns of no compromise and against all conventional wisdom in 2009 produced the MP4-12C a full carbon fiber chassis and a car fully designed and built by McLaren this time. Then the P1 followed and the rest is history. In just 6 years, the company has surpassed performance expectations and profit expectations. This was a kind of success story unheard of in consumer automotive history. This, shook the industry to the point, where well established manufacturers Audi, BMW are now scrambling to jump on the carbon fibre band wagon, setting up plants helter skelter to cash in and trying to replicate the success of McLaren.
What's even more impressive is that, a manufacturer in almost its first iteration, literally starting from scratch produced a road car the McLaren P1, that compares to the top models (carbon fibre monocoque and hybrid) Porsche 918, Ferrari LaFerrari from manufacturers whose road car production lineage spans decades.

¬∀ r ∈ Robots: r = Bad

Its interesting how, any discussion about AI or robots never misses terminator or "us vs robots" scenarios, but, generally misses the many "not so bad" robots in fiction. I guess, to some extent the more popular the movie, bigger the influence. These fears may not be baseless though. After all, I have heard that most of the robotics/AI research is usually funded by the military.

When one asks questions like, is steel good or bad? It depends on how it is used by us. But, this analogy may not quite work with robots when (and if) they reach the point of matching our intelligence. Then it may not be us, who decide how they should be used. Personally, I think the majority cannot be destructive as, it is not self sustaining. Anything that "survives" the various tests, that, nature throws at it, eventually has to have a majority in numbers of the constructive or the productive kind.

My favorite robots in fiction (and one real).

Spirit (Mars Rover): This fellow has been working all alone on mars since January 4, 2004. He surpassed all expectations of him and worked 21 times more, than what was planned for him. Day after day collecting analyzing samples and diligently sending its finding back to us, till he finally got stuck in Martian sand. Last we heard from him was on 1st May 2010. No bleep from him since.

How Viable is Technological Singularity?

Guest post by Anna Miller.

Now I don’t claim to be smarter than Ray Kurzweil, and I do realize that I’m throwing down some sort of a gauntlet by debating the viability of technological singularity on a blog that promotes synthetic life and progress in this field. But I still raise the question – how viable is technological singularity, the concept that technology will progress rapidly over the next few years, and that because human beings are incapable of pushing their brains and intelligence beyond a certain limit, machines will start to build machines that are more capable than them, and this recursive cycle will lead to a new race of super-intelligent machines.

Believe it or not, the first time I heard of this concept from a friend, I immediately thought, “Terminator”. Didn’t they make a sci-fi movie with this idea more than a decade or so ago? And do they not see the doom that technological singularity spells for the human race? If machines became more intelligent than the human race, how would we survive? And what kind of a world would Earth become if it was populated with machines that had no human emotions whatsoever?

No matter how advanced technology becomes, and no matter how intelligent machines become, it is going to be impossible to recreate the human brain. This is one organ that is beyond comprehension, let alone duplication or improvement. It boggles the mind to think of all that the human brain can do, and if Ray Kurzweil or anyone else think that they can make a machine do much more than the human brain can, well, they’re dead wrong.

Sure, a machine can be programmed to work for eternity without breaking down from fatigue; it can be taught to make decisions based on an accumulation of facts; and it can even be created to resemble a real flesh-and-blood human being. But then, can a machine make decisions that are based on emotion and not reason? Can it think intuitively and using a humane approach as needed during most crises? Or can it replicate human touch to generate comfort, pleasure and warmth?

Thanks, but no thanks; even if technological singularity was viable even 100 years from now, I would still prefer that the world we leave behind for our children not comprise monstrosities that we call technological advancement!

"Synthetic" Life



Most of us have heard in school, of life starting in a primordial soup from the inanimate - Abiogenesis. Then there was the experiment where they tried to recreate the conditions of how this happened billions of years ago - the Miller Urey experiment. It did not succeed in creating living cells but, it did succeed in showing that many essential items to produce life can be synthesized from non living things. It was only a matter of time when an actual living cell was created from the non living in a laboratory. Well, this is it. Not, exactly the same as recreating the conditions of the primordial soup - that would also need lots of time maybe billions of years to evolve. This - a shortcut by creating an artificial DNA and transplanting it into a new cell.

They call it synthetic life. But, I think this blurs the line between natural and synthetic.

An interesting aside - When studying Computation Theory, there was one thing that intrigued me then. When discussing about machines producing machines. There was an argument something like this -A machine that produces another machine is supposed to be more complex than the machine it creates. Because, a machine cannot be more complex than itself it cannot reproduce. But, then we went about discussing how a machine can get a description of itself and use that description in any way it pleases - to replicate or to adapt etc. The gist - the assumption ,that, a machine cannot reproduce is wrong. To think about it - imagine if we had a world of robots, what would the robots term as artificial or natural. For that they would have to have some absolute machine from which all other machines were derived. The most complex machine. But then, that is what had to be a wrong assumption.

Another digression - consider relative velocity - There is no absolute velocity. This is relative and is measured in reference to something else. I mean, if one measures one velocity against the other, to find the absolute, one has to measure that velocity against another. Eventually, hoping to find something that is at stillness or in motion in the absolute sense. Then one looks at light hoping to find the absolute - and the most amazing weirdness follows. Its speed in vacuum being constant in the absolute sense. But, no matter on which planet or moving body you measure it or from which "inertial" frame of reference you view the light on the moving body, this speed remains the same. And, no matter what its source an incandescent lamp or a star this speed remains the same. Now how do you measure the absolute velocity, when you cannot measure it against the speed of light.

Some thoughts to ruminate over.

Conan O'Brian @ Google


Yes, I am still alive, to the disappointment of some (Undead from the perspective of some of the more active readers). I have some unfinished posts in the works, so no fret [yelp... ].

Among the many interesting talks at Google, I think this stands out.

The Scheme of things

With the pipeline (SICP 6.001) at MIT, producing the most seasoned schemers, replaced with a one churning out seasoned pythons@ (6.00) - the population of schemers is bound to dwindle with time. Reasoned Schemers look on, on how their kind gets fewer and fewer. consing, caring, cdring and letting with lambda the ultimate produced a structured mind only to watch scheming go into obsoleteness? Even a reasoning mind is unable to fathom the reasons behind this move. But, MIT must have had good reasons for their transitions. I guess this is how a beautiful language fades into oblivion.

I am being bit over dramatic and this is old news. Scheme is a very interesting language, but "The Times They Are A-Changing". I guess for the little schemers it will be boredom of Java for a living§. Now run* and get freshρ. You may want to first run1, run2 ... so on, till you can run*. All that running made you hungry? - well have some tofu. What you had a (cons tofu (cons cheese (cons pizza (quote()))))? What are the health benefits of that? Don't askφ.

Petman prototype

Judgment day not too far ... Just kidding. I am pro robots. At least, till the day when they try to smack the living day lights out of humans. This is amazingly close to a "human walk". Interesting and cool.

Got me self a Donut

Got my self the android 1.6 update. New features like the Quick Search (across history, contacts, bookmarks, web etc), Gestures, test to speech and more.
Update 1.6 highlights

As before get it here:
HTC Developer Centre

Interestingly note that the radio image is the same for 1.5 and 1.6. So one can skip this part if one is already updated to 1.5.
download the SDK
download the radio image
download the system image
sudo ./adb devices
connect device using USB. But, DONOT mount from phone
sudo ./adb push ../../ota-radio-2_22_19_26I.zip /sdcard/update.zip
sudo ./adb shell sync
start phone in recovery mode:
press HOME button while restarting
Alt+l
Alt+s
HOME + BACK
done!

NOTE: had to erase the user partition this time as many apps did not work after the update.
enter fastboot mode (hold the BACK key while starting)
sudo ./fastboot erase cache
sudo ./fastboot update signed-dream_devphone_userdebug-img-14721.zip -w


to get to the settings menu (to enable wifi) without having a data connection in the FASTBOOT mode try this:
sudo ./adb shell
$ am start -a android.intent.action.MAIN -n com.android.settings/.Settings
Starting: Intent { act=android.intent.action.MAIN cmp=com.android.settings/.Settings }

My Android Dev Phone 1


Ah! finally a unlocked phone with an open OS that seems to be going somewhere. First, impressions are impressive. No branding of any kind on the phone. No mention of the word Google or HTC on the outside of the phone, except for the Android robot on a polygonized terrain. Opening the cover reveals HTC mentioned on the battery. For a first cut OS release, Android rocks.

Functions are intuitive and has very good integration with Google applications. One can't initially start the phone without creating/having a Google account. Plethora of applications are available on the android market place. And, I think a lot more will be coming soon. Apart from the default applications I downloaded the following free applications from the market place and gave them a try. Decent...
http://www.android.com/market/free.html

Compare Everywhere: Barcode scanner which returns comparative pricing of the items scanned.
GPS Status: Shows the satellites the GPS has connected to. Also, shows other information from the Compass and sensors on the phone. Pretty decent to have.
GpS Tracker: Can track GPS coordinates real time. Also, has a functionality to get activated by SMS sent to the phone.
Homer Soundboard: DOH!
Barcode Scanner: Another barcode scanner.
Last.Fm: Yups they already have an official application for Android.

Opera: I will make this clear. The default browser Chrome on Android sucks on Edge connection.
Phonalyzer: Various statistics one always wants to know from one's call history/log.
SkyMap: This tool is awesome. It uses the phones GPS, compass etc. to show you the starmap with the names of the stars and constellations in front of you.
Screenshot: This is what I will use to post some screen shots soon. Does not work
SMS Backup: One needs this. Backs up the SMS'es to gmail.

Updating to Android 1.1

Recently, update 1.1 was released. Below is my summary of how to update Android. Don't follow these without first going through the complete official instructions here. Then again consider yourself warned.
