In a nutshell, TreeSheets is a mix between outliner, mind mapper and spread sheet. The documents use a nested structure of cells (like a spreadsheet where you can create work sheets inside of cells). Using this nesting, you can easily create outlines with multiple columns.

Using different rendering styles, you can recreate something very similar to a mind map, too.

And it needs only a little memory.

It’s too damn hot…

What I remember most is two things:

1. How long it took about 80 people around the pool to notice that a man was calling for help. He was calling and waving and a couple of people even waved back. But his plea for help somehow didn’t really register until I took the child from him and shouted as well.
2. The foam coming from the mount of the child as I dropped him on the ground outside of the pool.

Luckily, a doctor was close-by and managed to revive the child. He did first aid until the staff doctor from the hotel’s infirmary arrived. The staff of the hotel also called an ambulance that arrived only a few minutes later. All in all, when the near-death registered, professional help came quick.

If you have a child who loves to dive: Make sure they don’t take deep breaths before diving. They’ll lose consciousness without any prior warning sign – it’s called shallow water blackout. From the Wikipedia article:

Significantly, victims drown quietly underwater without alerting anyone to the fact that there is a problem and are typically found on the bottom[...]

Some tips for people who want to save lives:

• People who are about to drown don’t call for help – if they had the air, they wouldn’t be drowning in the first place. Look for signs of panic and utter silence. Playing children scream, shout and splash. Downing swimmers just splash.
• People move all the time. If you think something is odd, watch them for 10 seconds. If you don’t see any controlled movement in that time, call for help. Remember that water is never still. So if the hands float a bit, that’s not movement. Watch out of for leg movement, swimming moves, looking around (head movement). If in doubt, call for help – pulling someone out of water takes a lot of time.

I fondly remember this line from MAD magazine: If a student takes six hours to write a paper by hand, how long would it have taken had he used a pencil?

Maybe even longer:

In the next video, a couple of people had lots of books and lots of time and a lot of creativity went into it, too:

Some people only read books. Wimps! There is so much more you can do:

And last but not least: Something to enjoy like a great sunrise – “Seconds of Beauty“

But with Generics, you can do better: You can return whatever the caller wants.

How? Like so:

     public <T> T get() {
        @SuppressWarnings( "unchecked" )
        T result = (T) ...calculate the result...;
            
        return result;
     }

Use cases: Calling unknown methods or reading field values with the Reflection API. Instead of cluttering your code with casts, just write (where ReflectionUtils.invokeMethod() uses the trick above):

     Map<String, List<Map<String, String>> map = Maps.newHashMap();
     Set<List<Map<String, String>> entries = ReflectionUtils.invokeMethod( map, "entrySet" );

Cool, eh?

Unfortunately, Sun’s javac isn’t smart enough to determine a common upper bound between int and Object. So if you need to return int, you still need a cast:

     Map<String, List<Map<String, String>> map = Maps.newHashMap();
     int size = ReflectionUtils.invokeMethod( map, "size" );
