Only started with Perl4 and Perl5 in 1995. I was doing AWK etc for 12 years before that, and resisted switching. I've been doing OO since before C++ hit bigtime, with Objective-C and SmallTalk, so I really like the (no longer new) Perl5 OO style; and the Lispish Map style is also an old friend. What do I hack with Perl? All data that passes my way; systems monitoring scripts at $DayJob, weather data at night, and I cheat on NPR word puzzles.

Only wimps read the release notes first ... Memoes to Self

[ #27290 ]

Memoes to self:

1. Always read the release notes carefuly before and during and upgrade.

Luckily there wasn't anything important on the server that I tried to update from Debian 3.0/Woody to 3.1/Sarge withough following the recommended procedure in the platform-specific release note. For the DEC-Alpha platform, it's a just a wee bit more involved than the Ubuntu "just do it". (On DEC-Alpha, everything is a wee bit more complicated ... except Perl is 64bit out of the box, hence my fascination with it.) I tried to just do it and hosed the Alpha ... but since it was a standby system with nothing on it, which is why I was upgrading it first, no harm done expect I had to re-install 3.0 to try the upgrade again.

Upgrading Ubuntu 5.04 Hoary Hedgehog to 5.10 Breezy Badger was pretty slick. Not even in comparison, just slick.

2. If on a ADSL "broadband" not real broadband, doing one upgrade-over-internet is quite enough, don't try to do two different ones at the same time.

3. Math helps with KVM Switches

Knowing modular arithmetic makes using a KVM switch easier ... -1 mod 4 = 3, so to go BACK 1 step on the KVM, advance 3 to wrap around back ... sort of like two wrongs don't make a right, but three lefts do.
