The document criticizes various aspects of Java and the JVM such as pointers not being available which requires more complex instructions, garbage collection sometimes causing headaches in debugging, and the tedium of creating wrappers for different data types when other languages allow direct passing of data. It concludes that it's best not to take on extra work just because a technology is new and that it's often easier to implement functionality yourself from the beginning rather than relying on frameworks.

1. Or how I learned to stop worrying
and hate the JVM

2. In the beginning...

3. But hey, no pointers!
Pointers are a tool that points to where something
is located in memory rather than by its name
For example, saying hey you in seat 8 instead of
someones name in a class
Java will handle these for you!

4. The JVM is horrible and you should
hate it

5. This makes the jvm bad for things
Bad for big equations and complicated
instructions, basically anything you want to do at
a high level

6. Its garbage day

7. Garbage collectors just make
headaches
They sound handy, but they can drive you insane
looking for bugs that don't exist.

8. Wrappers

9. It gets old fast
Having to write a new wrapper for every
combination of data gets tedious when you can
just pass it in other languages

10. But the documentation is good!

11. And there are tons of communities
available

12. What I've learned from becoming a
bitter java veteran
Doing more work than
you have to just
because something is
shiny and new is
kinda dumb
It's much easier just to
do the job yourself the
first time

13. Questions?
