No one has asked yet, so I guess I have to: is the Perl binary written in Perl?

-----


No. The article says:

> The only compiled code in this Perl/Linux system is: Linux Kernel (not currently built with this project), perl, and uClibc.

The Perl 5 compilers that currently exist all produce code that still needs to be linked to the perl library, which itself is written in C, not Perl. (I don't know the current situation for Perl 6).

-----


Rakudo Perl 6 runs on Parrot, which is written in C. Niecza Perl 6 runs on .NET/mono, and its libraries are a mix of Perl 6 and C# code.

Anything I would use Perl for, I use Ruby instead.

A fall when a bunch of people can suddenly sell is a normal thing.

And those insiders should sell parts of their positions. They are very heavily invested in FB and need to diversify, even if they believe FB is a very wise investment. Many insiders probably have more than 90% of their portfolio in FB stock.

All of this "giving away" of stuff has stopped our society from reinventing the wheel.

Unfortunately, the people "giving away" spend a lot of time reinventing fantastically-different but only-very-marginally-better wheels. Every week I see on HN about some new language or framework someone has invented that fragments the market even more. If you aren't being compensated in dollars, being compensated with being "the inventor of X" can come close, so there's a big supply of this.

Several times I've been a company that says "the way the rest of the industry does X is stupid."

Sometimes we broke the rest of the market, sometimes we captured a really big piece, sometimes we had to give up and do what they all do.

"Missing stop signs" is one place where a google car would be great, since they pre-map the area and would know a stop sign has disappeared. Knowing that would cause them to slow down and be even more careful.

Autonomous cars never get distracted, have 360 degree vision, look at all things all the time, and can react in tens of milliseconds versus hundreds of milliseconds. I'd trust that over a "professional driver."

There's a classic science fiction story that I cannot remember now where people do exactly that.

If it becomes a problem, the car can transmit images of the jaywalkers to the police.

The people doing this have talked about how their autonomous car met another company's autonomous car. There didn't seem to be a problem.

Really, when there are more autonomous cars on the road, each and every one will get better from their neighbors. They can directly share the data they see and what they are doing. The network effects will be huge.

The 4-way stop was something they had to change from the ideal setup. The google car was obeying the law and waiting its turn and never getting it. They made it get more aggressive the longer it waits and now it gets through them just fine.

I think $10,000 is a big over-estimate, but even that would be spread out over the life of the car. I'd happily pay $1000 a year to not have to worry about driving.

I'd happily pay $1000 a year for a car that doesn't drive itself.
