Firefox problem with Ubuntu

Following up on Jammy Jellyfish and System Updates I have been using Tyrone, my newer Ubuntu 22.04 system, for my daily work. In doing so I found an issue with Firefox: The “Save page as” “Print/Save to PDF” commands were not working on that machine under Ubuntu. I tried various Firefox troubleshooting options, but they did not help. The commands work fine with Firefox under Windows, and also with Firefox under Ubuntu 22.04 on another system (Donegal), which, however is an upgrade from 20.04 rather than a clean install. I even tried uninstalling and reinstalling Firefox

On Thursday, Sept. 1, Mia McDavid and I drove to Chicago for Chicon 8: The 80th World Science Fiction Convention at the Hyatt Regency Chicago . This was our 5th Chicon. Previously we had attended:

Despite some glitches, we really enjoyed the Con, and visiting downtown Chicago again.

Installed ChromeOS Flex

I have a Lenovo ThinkPad X130e laptop. It came with Windows 10 Home Edition, which does not work nearly as well for me as the Profession Edition I have on other systems. It hangs frequently. I have also installed Ubuntu Linux on it, which does better.

These days Chromebooks are everywhere, so I have become curious about Google’s Chrome OS Flex, the installation of which can turn an ordinary old (but not too old) PC into a Chromebook. Continue reading

A Windows Memory Leak Problem

Recently there were a few times when I was using VS Code under Windows and the response time got worse and worse. A reboot would fix it temporarily, but the problem would come back. A look at task manager showed that the Shell Infrastructure Host, sihost.exe, was using a lot of CPU. I thought about killing the process, but the dire warnings about system instability deterred me the first time.

College Reunion

I spent the weekend of June 16-19 at Carleton College. The occasion was my 50 year class reunion, for which I was a member of the gift committee, which in turn was a part of the overall planning committee. Mia (my wife) and I had a room on the third floor of Watson Hall, “3rd Watson” was how we would have referred to it back in the day. I don’t know if the current students refer to campus locations like that. I lived on “6th Watson” my senior year.

Time in Windows and Linux

By default, Windows assumes that the local system clock is set to local time, and updates it accordingly. Ubuntu Linux assumes that the clock is running UTC (essentially Greenwich Mean Time) and will update it on that assumption. Since it knows your location (you specified it at installation, and hopefully updated it when you moved) it will display the correct local time just like windows.

The problem comes when you have a dual boot (Linux and Windows) system. When you reboot from one OS into the other the new OS will assume the system clock is behaving according its own rules, even though the other OS was following its rules. To fix this:
