The question is, who is "you" and when does that checking happen? I don't do a lot of work in Python, Ruby, etc. and all of the programmers that I know who do are fairly young and working on fairly small projects so they don't have a good answer for refactoring.

If I change the arguments to a method in a statically type language any place where I forgot to change the call to that method will be exposed at compile time. As far as I've been able to learn so far, in most dynamically typed languages that check won't happen until runtime. The pat answer to that is "you should have unit tests that cover everything" - but getting complete code coverage is hard and for large projects, the test suite takes a non-trivial amount of time to run - usually much, much longer than compile time. So, you wind up with bugs at runtime. Or is there a better solution?

OK, that's bullshit.

Technically, I see how it works but why would a merchant accept this thing? It doesn't look like a credit card and it's missing all of the anti-fraud elements built into the physical cards. According to their FAQ, Coin is trying to substitute an image on your smart phone plus their gadget for your physical card but I don't see that any of the actual credit card issuers are actually endorsing this. As a merchant you might be in violation of your merchant agreement by accepting this thing.

The Blu-ray disc needs to be mounted before it can be accessed. The ratio of robotic mechanisms to discs becomes important. If you need to mount ten discs, it takes ten times as long (if they're all using the same arm) whereas you could spin up ten hard drives simultaneously.

I've worked with large scale robotics since the late 80's. The performance of the arms has not increased significantly since then. When you're dealing with scientific datasets or backups it's not as much of a problem. In random access storage, though, it starts to be an issue.

Don't whiz on the electric fence!

Things like pricing can always be messed with. I think the maintenance issue, as the network grows, will become challenging. We'll see, though.

And in 1900 the same arguments applied against gasoline cars and you could get food for your horse, have a stable to keep it in, find a blacksmith to put new shoes on your horse, etc. just about anywhere.

The technology for EVs is still pretty early and just starting to improve. Give it another 10 years and it will probably address most of your concerns.

Superchargers aren't "free" - you pay $2K for access and then it's "free" for the lifetime of the car. This guy thinks that Tesla actually makes money on the program

Some people like nested virtual machines, some people like candy colored buttons. What else are you going to do with all those resources? :-)

Despite the name, DOS was not an operating system

It's kind of silly but no worse than network file systems. And, containers don't have that virtualization overhead.

It might keep a few out but there are people who get their jollies out of trolling and the outrage that they create and might be willing to pay a few bucks for their hobby. It's been going on at least since Usenet (mid 80's).

I do enjoy small scale discussion on Facebook. I usually limit people who can post on my comments to friends of friends and that keeps the discussions more civil and usually more relevant. Perhaps the real problem is just that the number of people who can post a comment on many discussions is just too large. There is the risk of living in an echo chamber, though. Maybe a discussion site that creates groups with a representative sample of views, etc.

They get an unlimited bonus structure so that there's no limit to how much they will sell. Sales people are greedy bastards and they will follow the money trail management creates, regardless of whether it is good or bad for the company. Structuring the sales compensation is very important - I've seen many instances where the salespeople are doing things that are not good for the company but maximize their payoffs.

Why do sales people wind up in charge? Because they sell everyone else on how wonderful they are. If you don't have a management team with some real knowledge of the business you will wind up with self-promoters running everything.

Mmmm hmmm...don't bitch when the suits take advantage of you then.

See, if you were smarter you would talk more and work less and get paid more (I've been telling myself this for years. I think my line of bullshit is finally getting to corporate grade).

Yes, the business guys are often fond of telling everybody just what geniuses they are. I like to point out that when we were in college, we never talked about how smart the business majors were.
