My snowperson is learning to limbo in preparation for their dream vacation to Trinidad. (Over the weekend, Ito got its first significant snow in six years.)

A hard disk failed in a cheap (i.e. old) server at OVH Canada (Quebec). They were able to swap in a replacement within 45 minutes of my opening a ticket. RAID rebuild takes longer. Admittedly, the new drive is even older than the one it replaced, but I can live with that given their response time.

Thank you, Phil O'Brien and Simon Morris, for the wacky and occasionally brilliant "Matinee Idle" that has livened up Kiwi summers for over 20 years. A fun way to be introduced to some "music" I would never have discovered. www.rnz.co.nz/life/culture...

The hosts of the divisive show say goodbye, sharing a thoughtful message about AI as the broadcaster draws the programme to a close in its current form.

After 16+ years, the Open Education Resource Foundation is on the verge of closing as the current fiscal host pulls out. This has the potential to close WikiEducator which has been around even longer.

I was back in my old Kichijoji / Mitaka neighborhood and noticed there is a new vending machine offering gyoza, steamed buns, sesame balls, and more.

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.

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.

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.)
