Just My Imagination

by

There’s always been a few lines in that song that I could never quite figure out what the exact lyrics were. Using the video above was quite a revelation. I do not pretend to know why I thought what I heard made any sense.

Why does Joe Saylor sing before Patrick Bartley comes in?

by

I stumbled upon this video from George Collier’s Youtube channel and I’ve now listened to this a countless number of times. Since it’s so popular on Youtube, there are several commentaries and reactions to this, even one by Patrick Bartley himself.

But I don’t think I’ve seen anyone address why Joe Saylor starts singing at the very end of his drum solo. The video link above should take you to 12:50 in the video. He’s definitely singing part of the lick Patrick is about to play.

So is he singing because Patrick missed it? Was Joe early?

I see Patrick looking back to see where the bassist and trumpeter are so it feels like a cue was missed somewhere, but that’s what this makes this so fascinating. The band continues seamlessly and song continues and everything still sounds great. How do professional jazz musicians do this?

NASA APOD

by

I wanted the very cool images from JWST as my desktop background. And I figured that NASA’s Astronomy Picture of the Day (APOD) would contain a lot of these and so I looked around for utilities that would modify the background by pulling new APOD images.

I found https://github.com/randomdrake/nasa-apod-desktop but decided to fork it into https://github.com/kaytat/nasa-apod-desktop. There are some minor updates for Python 3, a script usable via cron, and some small feature enhancements related to aspect ratio.

Jurassic Park

by

I knew that many of the filming locations for the very first Jurassic Park were set in Hawaii. And I’ve always wondered about the location where the helicopter first approaches Isla Nublar.

Most Google searches suggest the Na Pali Coast on Kauai but I couldn’t find the little rock island that you see on the left in the video above. And by “find” I mean using the 3D view on Google maps and examining the entire Kauai coastline.

And that’s because this shot is not from Kauai, but Maui. This spot is known as Keopuka Rock or Jurassic Rock.

R.I.P. All my pictures … almost

by

I’ve kept all of my digital photos on an external hard drive. And that hard drive crashed – Linux just wouldn’t mount it. I let out an audible gasp after realizing the drive won’t come back.

Luckily I had dejadup running and I was able to restore the photos. Phew. But I didn’t backup everything on that drive and so I was wondering if I could get back all the other miscellaneous files I had on there. I don’t know what they were but now I was curious.

The error message in /var/log/syslog was:

The messages indicate that sectors 56 – 63 were bad but I was hoping the rest of the drive was ok. Since this was an older drive with no SMART capabilities, I couldn’t use any of those diagnostics. Since I couldn’t mount it, I couldn’t run any of the command-line tools. But I did have a lot of other HDD space free and so I attempted to create an image of the disk and repair the image.

After some Googling, I found these two sites:

Using a combination of ddrescue, losetup, and xfs_repair, I was able to remount the image. Success!

ddrescue -f -n /dev/sdf /mnt/external_hdd/bad_hdd.img ~/ddrescue.log
sudo losetup –offset 32256 /dev/loop2 /mnt/external_hdd/bad_hdd.img
sudo xfs_repair /dev/loop2
