@llewelly Standing in front of the sign with my camera... I NEVER NOTICED THAT! I think you're right!

I'm going to chalk this up as "street signs that I don't understand." Is that a hula hoop?

The Hacker Factor Blog: The Big Bulleted List of C2PA Issues
hackerfactor.com/blog/index.ph
I'm often asked if I have a list of C2PA problems. Yes, yes I do. Here's the current 27-page bulleted list. Any one of these issues should make companies reconsider any C2PA adoption plans. 27 pages? They should be running away.

My cellphones (with unlisted numbers) are getting tons of spam calls today. Is it just me, or are other people seeing this?

The Hacker Factor Blog: The Sideways Sidecar

C2PA permits storing authentication information in an external file. However, this approach fails to validate media and enables undetectable alterations.

Sheesh... I asked ChatGPT if it knew of any citations for a specific technology. It said yes, then it provided 3 FAKE citations. Why does anyone trust AI responses?

Really glad I stocked up on M5StampS3 embedded CPUs for IoT devices. The vendor has a big banner about new tariffs: m5stack.com/. I can't justify paying $75 extra for a $7.50 item.

Yesterday a bunch of items in my Amazon "wish list" increased in price. (The biggest was $21 increased to $44.) Today? Many of the items are "Currently unavailable."

Wow. I have a list of items at Amazon in my "wish list". Not that I plan to buy them, but I want to watch how prices change. Some of the items just increased in price by nearly 50%. And some of the "guaranteed delivery" dates increased to a month.

@mike805 Yikes!
Fortunately, my RAID finished after 3.5 hours with no problems.

2025-04-22

Ugh... One of my raids had a bad disk. So I replaced the disk. It recovered, but decided that it needs to reboot and run e2fsk. At best, this will take hours. Fortunately, it only impacts me, and not my users, clients, or anyone else.

OMG, this is huge news, incredible news, news that shows you really can teach an old dog new tricks! As of March 31, ARIN and the other RIRs turned off "ftp://"! Now you need to use "https://" to retrieve files from them.

@thedarktangent I'll take a guess: From left to right: Raekwon, Method Man, Masta Killa, and GZA. (With Jeff Moss in the middle, filling in for Ghostface Killah.). Am I close?
