I bought a very small laptop to use with radio work in the field, and the screen resolution is a bit small (1366x768). Pair the small display with current desktop environments' tendency toward chunky, touch-friendly interfaces, and it doesn’t allow one to cram much on the screen.
My desktop environment is Gnome, so I slimmed it down with some stylesheets:
headerbar {
margin: 0 1em 0 1em;
padding-top: 0;
padding-bottom: 0;
border-width: 0px;
font-size: 12pt;
min-height: 0px;
}
headerbar * {
margin: 0;
padding-top: 0;
padding-bottom: 0;
border-radius: 0;
border-width: 0px;
min-height: 0px;
}
headerbar box {
padding: 0.1em 0.5em 0.1em 0.5em;
}
WSJT-X is a QT app, so I scaled the fonts there to make everything fit better by setting the DPI in a launch script:
#!/bin/sh export QT_FONT_DPI=75 /usr/bin/wsjtx

Upon the release of Pop OS 20.10, my System76 laptop and my Arris router started having some disagreements. The laptop would drop connection every couple hours and not reconnect itself. I’d see the little question mark in the WIFI indicator, and I needed to manually turn WIFI off and back on to restore the connection.
I found mentions of this behavior in Ubuntu and in Pop OS forums, and supposedly newer NetworkManager from Gnome would fix it, so I suffered and waited for the beta of Pop OS 21.04 to be available. That didn’t fix it, so I started digging around some more in System76’s page for Troubleshooting Wireless.
I picked my way through the tips and applied some of them. Disabling band steering in the router finally seems to have fixed the problem. I’ve kept my WIFI connection up and running for days now. I didn’t need to name the 5GHz and 2.4GHz networks differently.

Ben’s birthday is approaching, so I picked up the inexpensive Amazon Fire Tablet from 2015. It’s running FireOS 5.1.x.
He played with it running stock for a week or so, using it to mostly read library books, and of course, to play some games from the Amazon Appstore.
Reading was the main purpose to have the tablet, but I also wanted it for communication and organization. That means getting the Google Apps installed on it. The only things available in the Amazon Appstore were these shell apps that were nothing more than a wrapper aronud a web pane, so I needed to proceed to install the Google Play framework and app store.
Before even buying the tablet, I had found some links, so I was pretty sure it could be done. I started with a post on XDA which got me the link to an all-in-one ZIP of everything I’d need.
It came with the APK files and directions to run a Windows BAT file, which obviously isn’t going to happen on any machine I have, so I cracked open the BAT, and followed the script running the important bits by hand:
Login to the tablet as the original login — Ben’s secondary login didn’t work.
Enable Developer Options — Settings → Device Options → tap serial number serveral times, and the Developer Options will appear.
Enable USB Debugging — Settings → Device Options → Developer Options → Enable ADB to Enabled
Enable Side Loading — Settings → Device Options → Developer Options → Enable Untrusted Sources
I was on a Mac, so the USB drivers were already good, and I had Android Developer Tools already installed.
Unpack the all-in-one ZIP.
Run the commands at the shell:
# see that tablet device is listed adb devices adb install com.google.android.gms-6.6.03_\(1681564-036\)-6603036-minAPI9.apk adb install GoogleLoginService.apk adb install GoogleServicesFramework.apk adb shell pm grant com.google.android.gms android.permission.INTERACT_ACROSS_USERS adb install com.android.vending-5.9.12-80391200-minAPI9.apk # disable ads on cheap tablet, though I already paid to have it disabled. adb shell pm hide com.amazon.kindle.kso
After those couple commands, I found I had the Play Store icon, and fired it up, did the Play Services upgrade, and started installing the Gmail, Calendar, Hangouts, and Keep. I did find Inbox would crash after setup, but Gmail was fine.
