Top Posting

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?

It seems that major e-mail clients including Gmail encourage people to top-post and actively sabotage any other mode of operation. Recently I have discovered that with many top-posters the conversation is very inefficient, as top-posters when constructing their reply tend to stop reading after answering the first question in the original mail.

It is really hard to keep them focused on the whole mail, because for answering all the questions presented to them, they would have to scroll down and back again.

Perl6 - Rakudo

I have installed Fedora 14 Alpha in a virtual machine in order to test emerging technologies like systemd and Perl 6. I have not tried the Perl 6 language features yet, just did several small performance tests:

[root@nausicaa ~]# time perl -e 1

real	0m0.029s
user	0m0.012s
sys	0m0.018s
[root@nausicaa ~]# time perl6 -e 1

real	0m2.773s
user	0m2.137s
sys	0m0.635s
[root@nausicaa ~]# time perl -e 'for (1..10_000) { 42; }'

real	0m0.027s
user	0m0.008s
sys	0m0.019s
[root@nausicaa ~]# time perl6 -e 'for (1..10_000) { 42; }'

real	0m7.705s
user	0m6.779s
sys	0m0.922s

I know Rakudo Perl is not optimized yet, but taking over two seconds just to start the interpreter makes it unusable even for playing and trying.
