Recover Server Again

bediger8@gmail.com (Bruce Ediger) — Sat, 03 Oct 2026 19:33:00 -0600

A pickup truck crashed into an electric pole just down the road yesterday. The pole fell partway over, held aloft by the power cables. The electrical mains power dropped abruptly. My Dell R530 and Qotom fanless server are powered through an uninterruptible power supply, but only the R530 has the USB connection and runs apcupsd to get notifications that the UPS is running out of energy.

Trapped Some Web Scrapers

bediger8@gmail.com (Bruce Ediger) — Sat, 03 Oct 2026 19:16:16 -0600

Recently, I found On Bots, an interesting project from 2006-05-03. Someone constructed 2 billion numbered web pages, arranged as a binary search tree via hyperlinks. They tracked accesses of the web pages for a year. It looks like they were interested in how much of their binary trees got explored, and in what order more than anything else.

Have you ever eaten lunch at an Indian food buffet? If you haven’t, you really should go to one the next time you go out for lunch. They’re amazing.

When you’ve gone a little ways down the buffet line, have you ever discovered something you really like, but you don’t have a good place to put it on your plate?

Compose Bijective Base 10 string for an integer

bediger8@gmail.com (Bruce Ediger) — Fri, 28 Aug 2026 07:55:22 -0600

I found a fairly fast way to convert strings representing Base 10 numbers to strings that represent Bijective Base 10 numbers. That’s a string-to-string conversion, no integer type is involved. What happens if you have an integer type variable and you want a Bijective Base 10 string representing it?

Earth's Obliquity

A paper I read on astronomically calibrating pre-Cambrian sediments to get a more accurate chronology of important evolutionary events led me to look up where Earth’s rotational axis has pointed over geological time.
