So weird, I literally updated bash minutes before seeing this post about bash. I followed these instructions to enable it as default https://johndjameson.com/blog/updating-your-shell-with-homeb...

Just watched the How it works video. When the coupon increases as more people use it, doesn't that hurt the merchant? Or is the goal to just get more people to buy?

Is there a reason why it appears more populated and dense in the middle as opposed to the upper or lower regions? Is that the plane of our galaxy, or something to do with the light?

Yes, it's the plane of our galaxy. If you click show constellations and objects, you can see where we are in the spiral, bottom left.

What is the "shadow" that appears to go across the plane in a very irregular manner? Is there a local dust cloud obscuring parts of the main plane?

It's the Great Rift http://en.wikipedia.org/wiki/Great_Rift_(astronomy)

Interesting, I haven't seen this clustering from looking at the sky before - is it because this is more sensitive than the naked eye?

This is one of the downsides of living in a heavily populated area. It's quite visible once you get away from the light pollution around cities.

It's called the Milky Way!

In general, you can't see it if you're anywhere near an urban area.

You can see it in areas with little light pollution (although not quite like this image), otherwise most of the stars are too faint.

It's a side view of the milky way - our galaxy. You can see it at night if you look up, and you live far away enough from a large city or light polluted area.

The flip of this would be Yelp retroactively charging users for looking at reviews. It's ridiculous.

Wouldn't it be even more of an engineering battle if the drivers were replaced with computers?

A lot of NASCAR fans argue that F1 is just that - driving skill has been replaced by technology. I think that's nonsense. Better cars are an advantage, but ultimately, it's the driver's nerve and imagination that wins. I'd choose a lesser car with a greater driver any day.

Completely agree. On Top Gear they have a segment where they have a celebrity drive a 'reasonably priced car'. They had to create a separate scoreboard for F1 drivers, because they are all so much faster than anybody else.

They also note that the F1 drivers take certain turns differently from every other driver.

I wouldn't. Not in F1, at least. Not if you wanted to regularly come in the points. You could stick Vettel in a Marussia, and he'd still finish near the back of the pack.

Vettel won his first race with Toro Rosso. While he may not be able to win in dry conditions in a Marussia he could certainly get the most out of the car, and help the team build it over time.

True, but then you have the teammates to compare. Vettel / Webber, Alonso / Massa, etc. Same cars, very different records.

There will certainly be a driverless racing circuit one day.

Soon, if Google's automatic cars ever become available.

It will probably start out as an underground thing.

Well the closest today is the DARPA Grand Challenge http://en.wikipedia.org/wiki/DARPA_Grand_Challenge.

That would be great. Though, it probably wouldn't be as popular. People like to see people compete. It would be fun to program one of those things.

http://opensignal.com Don't know how accurate it can be.

It has no useful relationship to reality. It relies on a self-selecting group of people to download and run their app to collect data, and then presents that data in what I'm sure is a precise but utterly inaccurate form.

If you believe it, there is no signal from any carrier at either my current home in Washington, nor my previous home in Santa Clara. And there is certainly no T-Mobile, AT&T, or other GSM carrier signal to be found anywhere near my current home (my AT&T iPhone stubbornly insists on working regardless).

Yes. I use BitBucket because it allows free private repositories. No problems at all.

Oh, one byte is fine for the level. No one will ever come close to reaching anything higher!

Well, two bytes is quite the challenge then, isn't it?

I like the lowercase b because it translates to bit. And it looks like a coin.
