It did, and he was (is).

Ctrl + D
Deletes the current line. By far my most frequently used shortcut in Eclipse.

Ctrl + Up Arrow, Ctrl + Down Arrow
Moves the current line up or down. Also very frequently used.

Ctrl + /
Sets the current line to be a comment. This works as a toggle: if the current line is already commented, this shortcut un-comments it making it active code.

If you type all the upper-case letters in the name of a class, then press Ctrl + space, Eclipse will replace it with the name of the class. If you type only some of the upper case letters, such that more than one class can match, Eclipse will open a list and allow you to select the class you need.
Focusing on memory is too narrow a scope for the concept of "expensive". Expensive means consuming more resources than we would prefer. The resource in question could be memory, but often we are talking about the time necessary to complete the task. Sometimes we're referring to bandwidth. Our application may depend on a remote service; calling that service might be expensive because our bandwidth is limited, or it might be expensive because the request takes a long time to serve. A database call could be expensive if we have a lot of logic and joins in our SQL, or if we're doing locking and managing transactions. We have to consider server resources in addition to just what the application needs to run locally.

It's worse even than that. When we "spring forward", they are in the dark again.

so this leads to the question, with so much daylight, what is this daylight "savings" supposed to do?

Save non-renewable energy.

So we're told, but in fact it doesn't do this:

This is something we would do in our application with colspan. Is that an outmoded approach?

Documentation is unclear, but I'm pretty sure that when a Backing Bean implements Converter, it's intended to make the backing bean as a whole self-converting. In other words, if BeanX implements Converter, I don't expect the conversion methods to be receiving/emitting anything that isn't a BeanX.

You are right! That´s why my bean doesn´t implement Converter!!
My Generic (BaseConverter) does!!

What's the advantage of a design like this? At first glance I would much rather have a separate, dedicated converter class that works on a specific type.

I'm not taking the time to tell you how terrible the experience was of clicking on a link. I'm taking the time to tell you that I agree with the OP: in my opinion those ads undermine Java Ranch's credibility.

And you would like for me to remove these ads because you might click on it again?

I know you don't care about that, and in your place I probably wouldn't either. I don't even really care that much: I clicked once, now I won't, the end. I never said you should remove the ads.

Because of my amazingly attractive prose that does not sound like advertising copy?

Because of its position at the bottom of a thread, on the same background color as the other thread posts, horizontally aligned to the other thread posts.

The down side for me is that somebody tricked me, so I trust them less than I did before.

Disingenuous. "I agree. Here's the link" is not advertising copy.

What you say is contradictory: if you believe we know they are ads, then why go to the trouble of making them look like forum posts? I'm with Joanne. I clicked on the zkoss banner ad because I was interested in their product. I clicked on the fake-post footer ad by accident, thinking it was a forum post. You know the saying, fool me twice? Well you fooled me once. And you successfully trained me never, ever to click on another fake-post footer ad on your site.
