If a mind mapper is wasting too much space and an outliner is too restricted, try TreeSheets.
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.

If you want to return anything in Java, you usually use Object – with Java 5 and autoboxing, this even allows to return primitive types.
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" );

Mark Menard blogged about a hidden gem in Groovy which might be useful when you use closures a lot: Binding properties to a closure after the closure was created.
Remember, it’s simple to bind properties to a closure when those properties exist before the closure is created: Just define them. But how could you create a library of closures for user to consume?
def c = {
println a // a isn't know here
}
def a = "Hello"
def binding = new Binding ()
binding.setVariable ("a", a)
c.setBinding (binding)
c.call()
As you can see, the property a isn’t known at the time the closure is defined. The binding allows to “inject” it later.
Groovy!

Some concepts are easier to understand when you see a graph. With HTML5, a lot of data and a bit of time, you can build a system that can visualize things like “live span over number of children” or the sources of energy over time. Interesting that nuclear power, renewable energy and energy from crude oil is about the same level today.
This view seems to indicate that the GDP of a country starts to kick off as soon as each family has two or fewer children. But maybe it just shows that after financial constructs like derivatives and bonds allow to accumulate enormous wealth in a short time. “Correlation does not imply causation“

Q&A for professional and enthusiast programmers
Time for a little celebration: My reputation on Stackoverflow.com no longer fits into 16 bits. Yay ^_^
If you’ve been living under a rock: SO is the Q&A site for software developers. If you write software but don’t have an account there is like being a rock star who refuses to perform before an audience 😉
Stackexchange has now 74 sites for many topics: Photography, playing games or writing them, role playing, Unix/Linux, Ubuntu, writing, physics, astronomy, mathematics, English/German/Japanese/French/Spanish language, (La-)TeX, cooking, home improvement, SciFi and Fantasy, parenting, economics, and many more plus more than 450 proposed sites on Area 51.

If you have an ugly flickering screen when booting openSUSE 11.4 on a HP ProBook 5320m, then do this:
xorg-x11-proto-devel” to build the driver (zypper install xorg-x11-proto-devel)cd xf86-video-intel-2.15.0./configure --prefix=/usr --libdir=/usr/lib64makemake install/boot/grub/menu.lst” Add “nomodeset” to ever line which starts with “kernel” and which doesn’t already have itNote: Do this remotely from a second PC – your eyes will be thankful. ssh and wget are your friends.
