Perl's "Regular Expression" Engine is one of the most flexible and powerful pattern matching and manipulation tools. "Easy" and "powerful" often behave like magnetic poles of the same kind: They can't be together. But the "s" and "m" suffix modifiers supported by the Perl RegEx engine aren't that complicated to understand but still very powerful.

Some errors are really hard to find: They appear only sometimes or only on live systems or within complex source that can't run manually using a debugger. Adding debug output might help, but might also be confusing as the DBI error code 4 "statement contains no result" does.
Data::ObjectDriver is a great ORM. It's easy to configure and easy to use, but not as powerful as DBIx::Class (which isn't that easy to learn and I actually prefer using a wrapper instead of "native" DBIx::Class, but that's another story). There is one major thing I missed with Data::ObjectDriver: JOINing foreign tables.
Eine der Funktionen, die ich selbst auf anderen Blogs sehr gerne nutze, aber bei MovableType bisher vermisst habe, war die Email-Benachrichtigung bei neuen Kommentaren. Jetzt (nachdem ich das entsprechende Plugin schon vor Wochen heruntergeladen hatte) funktioniert das auch hier wieder.
Perl has a great asynchronous library: AnyEvent. (There may be even more great asynchronous libraries, but it decided to use AnyEvent.) I recently had to lookup a lot of different hostnames and didn't want to do it sequentially (because every single DNS server might be down or wait until the reply is received).
DKIM may be called as PGP successor: PGP has been used by many people for signing their emails at a time when mostly technical related people had been using the internet. Today, few people still use PGP to sign their emails, but email servers took over this part using a technology called DKIM.
MovableType is still using the old, deprecated Digest::SHA1 module in some versions. Using the newer Digest::SHA is recommended and MT will switch in future versions, but Digest::SHA1 is currently still required for commentor logins in some versions.
I'm used to use dedicated or at least virtual servers for projects, but currently, I'm working on two projects which are using simple webspace instead without SSH access. A cgi-bin directory is all you need for Perl, but what happens, if a script dies without an error message?
I tried MovableType just before setting up WordPress for this blog. It didn't offer the features I wanted (okay, WordPress still doesn't have them, but it promised to have them and so it won). After trying out MT again, I want to have it. But what about my existing articles, comments, settings? That's (the only reason) why I'm still using WordPress.
Immer mal wieder werde ich gefragt, wie schwer eine WordPress-Installation ist oder ob ich ein Plugin für dieses und jenes kenne. Anno 2011 habe ich schon einmal eine Checkliste gepostet, jetzt ist es Zeit für ein Update.
