Zetta is the new Peta, or Zebi

The prefix after tera- should be 10005, or peta-. Therefore, after terabyte comes petabyte. Next is exabyte, then zettabyte and yottabyte. Those are powers of 100010 not 102410 ( which is (210)10). Really we should be saying gibibyte (102410)3 or (210)30, tebibyte (102410)4 or (210)40, pebibyte (102410)5 or (210)50, exbibyte (102410)6 or (210)60, zebibyte (102410)7 or (210)70, and yobibyte (102410)8 or (210)80.  From What Comes After Terabyte? | Britannica

Zoom on Mint / MATE 20201106

UPDATE 2020-11-09

Zoom got back to me promptly. The dialog box they also fixed. In My Humble Opinion this GNU/Linux Zoom Client is one of the finest examples of cross-platform software any company has developed and the customer service has been excellent in response time and punctually correcting software issues. Buy their annual subscription.

My difficulty installing they have provided instructions to correct, which work perfectly, and the installed client performs better as well. In the Linux Mint distro version zoom cannot use a virtual background, even though it can with Windows on the same hardware BUT in the provided “lastest version” it works in Linux almost as well as in windows. I am impressed.

The application “Zoom“ you installed from “Software Manager“, is a Flatpak format and is not published by us (Zoom company) but by a third-party publisher.
To fix this issue, uninstall the “Zoom“ in “Software Manager“, then download the deb package from https://zoom.us/client/latest/zoom_amd64.deb, install using the following commands:

  1. cd ~/Downloads
  2. sudo dpkg -i zoom_amd64.deb
  3. sudo apt-get install -f

The third command will fix the dependency issue.
Please let me know if you have any more questions and I will be happy to help in any way I can.


This post is written November 6, 2020 and applies to Linux Zoom Client 5.4.1 (53350.1027). This is a paid account, so if you are using a “free” account your mileage may vary. If Zoom Support contacts me with more information I will update this post accordingly.
Zoom is a popular conferencing app. A rare but notable trait is that Zoom works in any web browser, or as an installed Client App on Mac, Windows, and Linux. Several Linux versions are available at https://zoom.us/download.

The windows client works fine from this download page but when I chose the Linux Debian client for my Mint / MATE desktop it was missing two libraries, ibus and linxcb-xtest0. Maybe I should have tried the Ubuntu or Mint flavors, might not be their fault, but choosing Debian, Mint, or Ubuntu generally has worked the same for me as they all hail back to Debian…. The install failed, apt –fix-broken install did not fix it, and no other installs could be performed until I purged zoom with apt purge zoom. It purged nicely.

Zoom is in the Mint repos and installing through the Mint / MATE Software Manager worked flawlessly. So advice #1 is install from the repos with Software Manager.

Second. Most of it works flawlessly but some of the Settings i/f needs adjusting:

  1. The Settings dialog box covers up anything else, requiring me to drag the settings dialog box off the screen to the side to see and use the dialog boxes that it spawns. It also covered my Conky status monitor and task bar which are always on top.
  2. My system dual boots Linux Mint / MATE and Windows 10 from SSD, and I store all large data on separate spinning media. Clicking Change to change the storage location of the Zoom Video Recording provides a dialog box as one would expect, however when one browses to the desired folder the Open button is inactive and cannot be used to select the location. Choosing a specific file name will work, however one would desire a file name for a recording based upon some automatically determined text, such as the date and time the recording started.The edit box containing the path to the location in which to store the recording is not editable.
  3. I could not locate the Zoom configuration text file, if there is one: it was not a dot file in the user home folder, nor was it a hidden folder in the user home folder, nor could I find a trace in /etc, /var/* or /usr/*. The instinct is to merely edit the text config file and fix it but a better approach is to simply use a soft link. Zoom defaults the recording storage location to ~/Documents/Zoom.
    1. Using the GUI or command line
    2. Delete ~/Documents/Zoom
    3. Create a folder where you want the recordings stored
    4. Create a link to that folder (right click / create link with the GUI or ln -s <path-to-new-folder> ~/Documents/Zoom using command line)
    5. Cut and paste the link into ~/Documents (if you are using the GUI)
    6. Rename the link Zoom (if you are using the GUI, note the capital Z)
  4. Shouldn’t need to do this but it is a solution to a problem that should eventually go away.

Post Script: It still doesn’t fix the problem: when you finish a meeting Zoom says it must convert the video and then presents a dialog box to select a storage location, HOWEVER the Open button on the dialog box is always gray so it cannot be clicked, and there is no place to designate a file name for the recording.


Programmer Humor

I don’t normally post comics, but I grew up with the computer industry and programming. This just spoke to me. Actually “Sacramento” came a lot later – mainframes were only owned by the largest banks, who rented time on them to others, and the programs were loaded from large reels of magnetic tape placed onto tape drives and manually threaded almost like a movie projector.

XKCD.COM comic today, June 25.

This is a bit newer history than when I started. Prompt 80, Southwest Tech 6800, Smoke Signal Broadcasting, mother boards covered with molex pins into which daughter boards were plugged (there were no son boards), eventually the Atari 400 and then the 800, the Apple 2e, the Commodore, Sinclair ZX-80, the Tandy, and the Texas Instruments 99/4.

Skilz was getting a successful load or save with the cassette tape player (whence you stored and loaded your programs) with careful timing between the play / record buttons with one hand and your other hand on the keyboard to start the tape and computer together at exactly the right time. And they ran on CP/M, not DOS, so you had to re-compile your own since the hardware and I/O addresses changed between each production run for every computer made.

Ah! Those were the days! Then came the single sided five inch square 160K “Floppy Disk”! What a revolution!


Texas Virus chart 4/19

Joe here is the xlsx spreadsheet Data charted from https://dshs.texas.gov/coronavirus/additionaldata/ Accessible Dashboard Data – Updated Daily. Note peak around 4/15 should be back at March 15 levels around May 5. IF TESTING increases it will show as a jump in cases BUT the overall slope on the chart will still be working downward – in other words a bunch of people *have* had the virus & recovered but were not in the count before, so at the day they are added it looks like a huge jump.
