It’s driving me crazy. Not a smoke alarm, not the computer. I can’t echo-locate it. Cant really hear it much outside the room, but very distracting within it. Any ideas?

Turned out to be the UPS. Off to Frys to replace it.

Spent about $60 for 425 VA. It’s charging now, meanwhile, I’m just operating without one. Peace and quiet.
Generally, my need for them isn’t that great. My machine can survive a sudden power loss, and most of the stuff I do backs up automatically periodically. The main reason to have one these days, for me, is to keep my internet alive. The main fiber router in the garage has its own UPS, but I need to keep my wireless routers up if I want to use a laptop with power out.
Could be a lamp.
Turned out to be my UPS. Probably a dying battery.

Any idea why the UPS was making that noise? If it was coming from the speaker some UPS have, you might have RF interference from something else. Just a guess.
BTW, if you’re still trying to troubleshoot the comment-delay issue that sometimes occurs on your blog, I just spotted what might be a clue; the main page showed 3 replies, though non were visible on the screen that gives reply capability. Also, your update appears on the main page but not this one, so I’m guessing it’s a caching issue; we’re seeing, sometimes, cached copies.
I assume it’s a warning signal that the battery is dying, and needs to be replaced.
The problem will go away if you install the free plug-in available at this website:

I’ve always found it amusing that the only people who can actually hear that dog whistle is leftists.
Speaking of delays, I noticed it takes about 45 minutes for your blog server to generate a “next” link to a new post. I’ve had to change the way I read your blog to accommodate this.
Hmmmm…I’m overdue on updating WordPress. Maybe that will fix it.
