Excellent post. Would have left a comment on the original article but I'm not about to give permissions to a new app just to leave a comment. Please consider an alternate comment system.

Why does it require so many permissions?

"Access your data on all website Access your tabs and browsing history"

I hadn't seen that, thanks for the link.

When you reach a certain size, no amount of due diligence on your part can ensure that your changes aren't going to break something in some other part of the code base without automated tests. Do you think Google or Amazon gets by without unit tests?

It's interesting but I don't know if I agree with the conclusion that writing this small function in C would make maintenance too hard. How often do you expect to have to change it?

Hmm I remember seeing that video before. Extremely clever technology.

Looks very cool. There are a few typos littered throughout the page that the author should fix:

accessility -> accessibility maet -> met

I second the design comment. Extremely easy to jump in and start, no log-in bs, nothing to get in your way. The minimalist aesthetic is nice as well. If only I knew how to play chess..

Someone named Alex posted a good rebuttal to the hash function example. Very nice explanation of how hash tables work.

Pretty cool. The rectangular select tool doesn't work on my system (Chrome 9.0.597.107, Mac OSX10.6). I see tons of visual artifacts where it hasn't repainted correctly. See http://grab.by/9hPv

exactly the example I was going to cite. In Scala this would be

val b = a.exists(str=>str.forall(_.isLowerCase))

or

val b = a.exists(x=>x.toLowerCase() == x)

There's no way I'd start using functional programming in Java if it's this clunky. Just stick with Scala.

#2 can be replaced with a 'tree' command

#3 doesn't work for me on Mac OSX with Bash; the ! is interpreted as the last command. Not sure if this works in other shells

#4 is clever, but I would think if you're doing something that complex that you need to recall time and time again you'd make an alias for it.

#8 is clever. I love AWK. But not sure when I'd ever use this.

The rest were pretty bleh to me. Always looking for new shell kung fu but unfortunately this list did nothing for me.

So weird, my Kindle 3 crashed twice yesterday, something that's not happened in the 3~ months I've owned it. And I have a leather cover. Curious if this is why.

You didn't learn any lessons about.. how well it works? I had very poor success in my apartment, but I'd like to try it outside.

"Why be stuck in two dimensions when you can fly in three!". I don't know about the rest of you, but given how awful people drive while constrained to two dimensions, I'd be truly terrified to see the state of things if travel like this became ubiquitous.

Nice piece of data visualization there. +1 for using great circles instead of straight lines.

Agreed, that's very annoying behavior.

This is awesome. But the colors seem to interact badly with the terminal backgrounds in Mac OSX. I also can't get any of the function shortcuts (F8 = pastebin) to work; I just get gibberish instead. Also I get a crash when I resize the window:

I don't understand what the title of this post is supposed to mean. If this some tortured reference to the analogy portion of the SATs? If so, that's not the correct form. If not, please elaborate what that is supposed to mean.
