I added a new disk, removed one on my workstation. It is running Ubuntu 20.04. Booted up, and the drive letters have changed, and the md number of a RAID 1 array changed. So I updated /etc/fstab and went to mount the /dev/md1 array. The mount command completes without error, but the disk did not mount. Turns out, needed to:
systemctl daemon-reload
Then the mount worked, and I could add the new disk to the RAID 1 array.
G.M.’s Cruise Moved Fast in the Driverless Race. It Got Ugly.
“Half of Cruise’s 400 cars were in San Francisco when the driverless operations were stopped. Those vehicles were supported by a vast operations staff, with 1.5 workers per vehicle. The workers intervened to assist the company’s vehicles every 2.5 to five miles, according to two people familiar with is operations. In other words, they frequently had to do something to remotely control a car after receiving a cellular signal that it was having problems.”

Levelized Cost of Energy
Summary Report on EVs at Scale and the U.S. Electric Power System.November 2019
“12 GW of dispatchable generating capacity is equivalent to the aggregate demand of nearly 6 million new EVs”
“Assuming each EV travels 12,000 miles annually, consuming approximately 300 Wh/mi of AC energy [1], and assuming 4.9 % system losses [14] for transmission and distribution, then each EV will require 3.8 MWh/year of energy generation. For the 2030 low, medium, and high EV sales scenarios, this translates into 1, 8, and 26 TWh of incremental energy generation, respectively. These increases in energy generation are relatively small compared to the 100 TWh range shown in Figure 3. As the figure confirms, historically, there have been periods of time when the grid added in excess of 25 million vehicles-worth of generation per year, the equivalent of roughly 150% of annual new light-duty vehicles sales in the U.S. today [15]. “

Mehdi Hasan Dismantles The Entire Foundation Of The Twitter Files As Matt Taibbi Stumbles To Defend Itby Mike Masnick
Matt Taibbi is a hack and a bullshitter, with receipts.
Using Firefox, go to the item page, open the Firefox Web Developer Tools (Menu -> More tools -> Web Developer Tools). Click on the Network tab in the Tools section, then on the web page click on the video and play it.
In the Network tab, requests for audio_128kb-0.m4s to audio_128kb-16.m4s appeared, and video_720p-0.m4s to video_720p-16.m4s. I copied the URL for the video and audio requests (all the same but with a different -0 to -16 segment), and used wget to download the files. Each was 1-2 MB:
wget https://video.ebaycdn.net/videos/v1/8f1e79501860a64d9e245434ffffec91/5/video_720p-0.m4s
After 32 wget commands, the entire video was present. I downloaded segments from 0 up until after number 16, I got a ‘not found’ message letting me know I had the last segment.
Then I concatenated the pieces together:
cat video_720p-0.m4s >> video_720p.m4s
cat video_720p-1.m4s >> video_720p.m4s
...
cat video_720p-16.m4s >> video_720p.m4s
And the same for the audio segments. I put the cat commands into a batch file “cat.txt” and ran them using “bash cat.txt”.
Then ffmpeg was used to combine them and convert to mp4 format:
ffmpeg -i video_720p.m4s -i audio_128kb.m4s -c copy ebay_720p.mp4
