The editors' hall of mirrors and trickery

Little Nuggets of Good Advice:

• Don't use prototypes until you fully understand the issues in Tom Christiansen's article about them.
• Don't get preoccupied with performance; your time is more valuable than the machine's.
• Don't use indirect object notation.

Perl Annoyances (yeah, it has a few.)

• if (%hash) { ... } won't work as expected with a tied hash.
• There is no easy way to reliably determine whether a reference is a reblessed qr//
• Two argument open is used with <> (and subsequently with -p and -n) resulting in potential security issues.
• You need no warnings 'qw'; to do qw/ # / quietly.
• sub x { 1 for 1 } returns !1 instead of 1 like you might expect.
• Requiring values or keys to reset the each iterator is ridiculous. In fact, each sucks in general.

Some Insteresting Nodes

The wonderful series, Meditations on Programming Theory, by mstone:

1. MOPT-01 - assumptions and spaces
2. MOPT-02 - substitution and formal systems
3. MOPT-03 - identification, part 1
4. MOPT-04 - identification, part 2

Some Opinions

On Node Retitling

This summary is taken from a reply to Tanktalus somewhere under Consider this: What makes a good node title?:

The best titles are not the ones you think are best. In fact, the whole concept of best in this instance is a local optimization and a function of the searcher. Retitling nodes in an effort to bring them closer to our preconceived notions of what makes an ideal title is necessarily introducing inefficiency. Good search coverage is, essentially, an emergent phenomenon. The assumption that we can help it along by retitling nodes is fallacious.

A lot of &bull; ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••
