The API is. By faaaaaaaaaar the most work is going to be to learn all the NS_xxx classes and how you write and plug together an IOS app. The language on which this is built is small in comparison. The libraries and APIs and things that you manipulate is where the action is.

Same goes for Java. the Java APIs are waay more work than Java, the language. If you learn Groovy or Clujure, which both run on the Java platform, you still need to learn the APIs or you won't achieve much.

And so on for Ruby and any other language.

That said, I would shoot for Swift if I was a beginnner.

And you also have to schlep out to Hamburg's airport, which takes 30 minutes. And check-in. Which takes another 30 minutes.

In München Franz-Josef-Strauss airport is about 40 minutes per train from the inner city. Which means you have ore than an hour to your final destination.

So that took about 2.5 hours + the hour flight. Sure a bit faster, but much, much more hassle.

This is the case, yes. As afar as I recall the noise has something to do with a shockwave when the trains enters or exits a tunnel.

Tunnels and shockwaves are also the reason the high-speed trains are pressurised. Deutsche Bahn (who also runs 300+ kph trains) advertised a while ago for a physicist who is an expert on shock waves.

Look at the value of an actual business. The hardware on which the database runs is cheap. The data is the product of all the work of all the people who worked there for the last 10-15 years, in the case of companies that do not manufacture things. Do you really think thay paying a couple of thousand Dollars even compensates for that? If you pay an average worked 60000 per year, and you have 200 of them, that is a 1.2 mil per year, and over ten years you gave out 120 million bucks. In comparison to that, the datastorage container is a joke.

My father had a one man business (a drugstore). He once moanes about eh price he had to pay for replacing his borked backup tape drive. Until I pointed out that if his HDD fails without a backup HE WILL LOSE HIS BUSINESS. He saw the light real quick.

Oracle is the same for medium to large businesses.

Thanks for keeping the OSS Oracle/Apple/MS haters in the real world. Oracle does have attributes that PostgreSQL can't match, for large datasets. The problem is that a almost none of the hackers here work with really large datasets. The other problem is that hardware is cheap. The data stored on them is so expensive as be irreplacable.

That said, I use PostgreSQL for most projects because I don't HAVE really large datasets (I have a lot of small ones).

What do they define as a "sign-up" site. This can range from simple to horrendously complicated. The large project I worked on was also a sign-up site but for a federated society with branches all over the world, and each of those branches had different membership rules and products that they wanted to sell through or with the part I worked on.

It can also be a get-your-name-and-put-it-into-a-database kind of deal, which is not complicated at all.
