I assumed, at the beginning, that this was going to explain how
Hungarian notation made code look wrong. Instead he defends it,
despite having an inkling of what the /real/ way forward is:
"[Apps Hungarian was very valuable] ... where the compiler didn’t
provide a very useful type system."
He fails to develop that thought into reasoning that the best way
forward is to properly use typing. In his unsafe string example, what
he really wants is a "unsafe string" type*, that can not be directly
passed to his Write() method, but instead can only be written via a
write_unsafe method (that co-erces the "unsafe string" to whatever
With hungarian, it depends on the programmer to see "wrong code".
With effective typing, the compiler can automatically detect such bad
My bets would be on the latter to catch a lot more bad code than the

lack effective typing...
