It is November, and that means "Butt Sumo" (尻つみ祭り) time again at the local shrine here in Ito, #Japan. Contestants stand back-to-back on a raised dais and, at the signal, attempt to bump their opponent off. The winners are sometimes surprising.

Halloween 🎃 is appearing more and more in Japan.

Yesterday's silliness involved replacing the garish LENOVO BIOS logo on my old ThinkPad with the Tokyo Linux User Group emblem.

School kids have been practicing their drumming for the past two weeks for their ride in the float. Our community's dashi was hit by an elderly driver while making the rounds on Saturday, putting one neighbor in the hospital with broken ribs. We sat out most of Sunday's festivities.

It was festival weekend in Ito. More than a dozen illuminated floats with musicians are pulled and pushed around the neighborhood.

For the past 3 years, I've been using the Open Source SilverBullet PKMS to organize my notes in Markdown files. Its major feature is how programmable it is (first in JavaScript, now in Lua). SilverBullet's author is publishing a series of tutorials on YouTube.

Wow, it's been years since I encountered a "you can only use this site with MSIE" alert... except now it is Safari or Chrome.

JG1GPY showed off a clever, compact multi-band antenna at the SOTA JP booth at the Japan Ham Fair this weekend. A switch allows selection of direct feed (for 1/4 wave on 40m, with trailing counterpoise) or through a 49:1 transformer for end-fed on higher bands.

This weekend is the Japan Ham Fair 2025 at Ariake GYM-EX (the 2020 Olympics Gymnastics venue). A chance for the big commercial vendors to show off previews of their new equipment and a flea market to allow users to recycle older gear.

My SatNOGS station disappeared a few days ago. I get the RPi down from the pole, plug it in to the LAN and it is fine. It turned out the 2.4GHz radio had stopped on the crucial access point. (Everything else was on 5GHz, so I never noticed.)

NZART (The New Zealand Association of Radio Transmitters) is the only amateur radio organization I am a member of that still insists on publishing its magazine on paper. The March issue has just arrived. It still punches above its weight for a small organization, but I wish it were digital.

Ito is hosting a ramen festival for the next four weekends. Within a five-minute walk, I can try 28 different kinds of ramen from around Japan.

I managed to get my @washingtonpost.com Keyword score back under 7. (It is harder to work on the average time statistic, since this is a "second screen" game.)

A group of New Zealand ham radio operators has a VoIP interface to some of their digital voice reflectors. I have built a webapp that shows real-time Asterisk extension status using Go and SSE. github.com/DigitalVoice...

I updated my old ex-lease Lenovo X1 Thinkpad to Fedora Silverblue 42 without issue. Thanks to everyone that is making this so seamless.
