nebula··on Man arrested for filming Boston police with cellphone camera sues city, officers
True in most cases, but I think there might be exceptions like when dealing with an emergency like a hostage situation.

Pretty much every other cop movie that I watched had LAPD in it. I wrongly(?) inferred from that were good.
nebula··on Spirit Gets Stuck, Makes a Big Discovery
Wipers sounds like a good idea. Not sure why they didn't implement it in the first place.

Now that actually makes NASA look bad if they go around claiming that here was a problem that we could have taken care of by just adding a good old windshield wiper, but guess what? we didn't. But luckily we got saved by the fact that Martian sandstorms had been doing this job for us, which by the way we didn't know until we actually went there .... That doesn't sound very PR savvy to me.

A very interesting TED talk on Mars rovers: http://www.ted.com/talks/charles_elachi_on_the_mars_rovers.h...

Apparently NASA didn't expect them to function this long; on the dusty Martian surface, the solar panels should have been covered with dust completely, leaving the rovers dead long ago. It's a lucky coincidence that "sand devils" on Mars had been cleaning the solar panels and keeping the rovers alive.

Well, can't they be just disconnected? may be cut the wires off?
nebula··on Ask HN: Why not log into web sites via email without any password?
Generally, password reset links will have a timeout associated with them. Also, if someone does manage to use the password reset link in your mailbox and reset the password before it expires, you will come to know that your password is not working anymore, and you can act on it. It's not same as someone silently logging into your account through your email. This doesn't in anyway mean that it's safe to send password reset links to your mailbox if it's already compromised, though.

nebula··on The Amazon rain forest may be largely a human artifact
Interesting. I can't say I know Indian history thoroughly, but from what I know India never had slavery like America did. There were other social mechanism that were used to exploit human labor in India though.

can you elaborate on what people you are referring to here when you say they came to India and called themselves Indians.

AFAIK, there is a lot of controversy surrounding the history 'Aryan invasion of India', but I haven't come across any history text that suggests that Aryans turned the natives into slaves.

nebula··on The Amazon rain forest may be largely a human artifact
I guess the 'Indian' here is referring to native Americans.

It amazes me that a bunch of Europeans occupy the Americas, call themselves Americans, and call the people who have been living there Indians.

I'd much prefer to read blogs via an NNTP reader

If you use Thunderbird RSS reader to read blogs, you pretty much get the Same look and feel. I was used to Thunderbird NNTP client, when I started adding blog subscriptions to Thunderbird, the transition was seamless

nebula··on The Nobel Prize in Physics 2009
While I agree with the "test of the time" point of view, I don't think the other part of your argument makes much sense:

1)better alternative model: generally it would not be that hard to guesstimate the possibility of a significant improvement in the very near future. And even if someone comes along and proposes a better alternative next year, I don't think there is anything to feel humiliated about, as long as the original work that was recognized by the award is really Nobel material.

2) Disproving the original model/theory: Do you know of any theory/model in physics that was considered proven to be correct, and later disproved? improvements, enhancements, yes but disproved?

nebula··on VMware May Be Microsoft’s Top Rival After Google
it(MSFT) is competing in too many different arenas

That is one of the reasons I don't like them. Whenever someone comes up with something innovative, MSFT jumps into that area, copies the concepts; uses the financial muscle and its huge presence the existing markets to kill the competition. Netscape is only an example of that strategy. It's a bad thing for a lot of potential startups.

You are absolutely right. Look at http://storagezilla.typepad.com/storagezilla/2009/08/vmwares...

For some perspective on Vmware's strategy in this area.

nebula··on The Hacker Survey
The data being collected is purely demographic. And I don't think that the data set would be very big either. Around a thousand entries even if most of the HNers take interest?

I am not able to imagine anything significant that can be done by using this data as training set in a machine learning algorithm. Is it possible for you to elaborate a little bit on what you intend to train your algorithms to achieve?

nebula··on Hacking a Google Interview - MIT's guide to Google interviews
Any definition of polymorphism should at least mention something about the method that is invoked depends on runtime data, and is not resolved (or known) at compile time.

At least in C++ world, it's not true. There things like compile time polymorphism, and run-time polymorphism.

And by the way, why do you think polymorphism should be based on run-time data? simpler things can be achieved at compile time with static analysis, which many OO languages do [C++, and Java for sure].

Just because it's simple to do, you don't have to declassify it from being polymorphic.

Linking to such a thing is a bad idea: i) people can accidentally click on it ii) you might be contributing to its Page Rank iii) The fact that it's linked from HN, gives it certain credibility.

can you please consider making it text, instead of hrefed?

nebula··on How do you scale your web application?
What are the effective strategies to use when the bottleneck is disk I/O? We have memcached to cache data that is frequently accessed. However our usage pattern is such that repeated access of data in a short span of time is rare.

nebula··on Checking out of 'Hotel America'
Are you kidding? or do you have a stone for your heart?

An innocent eleven year old kid died because her parents are morons, and you respond to that with a wisecrack taken out of context.

<quote>

The night before she died - and she would have been in intense discomfort - her parents called the founder of a religious website and prayed with him on the telephone. But they did not call a doctor.

If Kara had been taken to hospital, even at that late stage, insulin could have saved her. She could have been home in a few days and chirpy by the end of the week, as my son was.

nebula··on Light slowed down to 38 mph
<quote>Einstein and just about every other physicist insisted that light travels 186,000 miles a second in free space, and that it can't be speeded-up or slowed down. But in 1998, Hau, for the first time in history, slowed light to 38 miles an hour, about the speed of rush-hour traffic. <quote>

I wouldn't have been surprised if a newspaper journalist used dramatization that indicated as if Einstein is proven wrong. I didn't expect that kind of dramatization when reporting scientific matters on news.harvard.

Of course, Einstein is still right. All these experiments slow down the speed of light when it's traveling in special matter at special temperatures. Constant speed of light in free space is a necessary condition for Theory of Relativity be correct. If that condition is found to be incorrect, our current understanding of the universe completely goes for a toss;

nebula··on Why IT Happened in Southern India, an Unorthodox Explanation
Factually completely incorrect.

1. IISc was setup by Tatas, a private company, not by Indian Govt. Also IISc, then called Tata Institute of Science was established long before (around 50 years) British left India; nobody at that time had any clue that there was going to be Pakistan forked out of India, much less that it's going to have nukes.

2. Narayan Murthy didn't work in any of the organizations (IISc, DRDO, HAL) that you have mentioned. In fact he hadn't worked in Bangalore before Infosys was setup.

3. Patni, and TCS were there long before Infosys was founded. Narayan Murthy was working in Patni when he decided to start Infosys.

From the article:

"This is an extraordinary game and certainly not representative of the average revenue from other paid apps in the App Store. But it also isn’t even currently on the top list of paid apps, and it continues to pull in substantial dollars, spiking, we hear, to as much as $60,000 per day."

<quote> One time I sat down in a bath where there was a beautiful girl sitting with a guy who didn’t seem to know her. Right away I began thinking, “Gee! How am I gonna get started talking to this beautiful nude babe?”

I’m trying to figure out what to say, when the guy says to her, I’m, uh, studying massage. Could I practice on you? </quote> :)

nebula··on Microsoft Internet Explorer 8 at the height of cynicism
Or better, can someone quickly release an FF extension which can beat this? That would be an interesting counter strike :)
nebula··on Microsoft Internet Explorer 8 at the height of cynicism
I wonder if they are checking the firefox version number

I guess not. I use FF 3.0.x and they said "old Fire Fox". It looks like many people are actually downloading IE8 to participate in this. Hopefully, this actually may not change the market share of IE vis-a-vis its competitors. If you are an FF user, even if you download IE8 and participate in this contest, you are most likely to stick to FF. IOW I'm hoping that the downloads won't actually translate to conversions from other browsers. One good thing that might come out of this is some IE6 upgrades to IE8.
