Back in August “I upgraded my Ubuntu 20.04 (Focal Fossa) systems to 22.04.1 (jammy jellyfish).” At that time I noted:

Chicon 8
Thursday
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:
- Chicon 7 (2012)
- Chicon 2000 (2000)
- Chicon V (1991)
- Chicon IV (1982)
Despite some glitches, we really enjoyed the Con, and visiting downtown Chicago again.
Jammy Jellyfish
I upgraded my Ubuntu 20.04 (Focal Fossa) to 22.04.1 (jammy jellyfish), the current LTS release, last week. I simply followed the prompts from the Software Upgrader. The updates succeeded and the systems are completely useable, but there were a couple glitches.
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
Some Web Site Updates
- Added a brief bio.
- Consolidated my Ancient History and Early Modern History pages under a general History page, adding a new Medieval and Renaissance History page.
- On the three history subpages, and on the Computers and Physics and Astronomy added direct links to some of my more interesting (IMHO) blog posts in those fields.
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.
Keeping Slackware Current
What I wrote in Slackware Diary – 3 about keeping Slackware up to date is not correct:
slackpkg update gpg slackpkg update
Does not do the job. A closer look at told me that I had to also run
# slackpkg install-new # slackpkg upgrade-all # slackpkg clean-system
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:
Free42 on Ubuntu
I noted in Slackware Diary that I had installed Free42 under Slackware. As I wrote in 2006 I fell in love with HP calculators and their RPN notation back in the 1970s, and still find the conventional algebraic notation rather awkward. I no longer carry a physical calulator, but I have Free42 installed on my phone and my tablet, and on my Windows systems. Now I also have it on Slackware. So I circled back to see if I could install in on Ubuntu.
Slackware Diary – 3
Following up from last time:
gmcdavid@Tyrone:~$ flatpak uninstall com.visualstudio.code gmcdavid@Tyrone:~$ flatpak uninstall com.visualstudio.code-oss
I was prompted for the root password. I may come back to Flatpak on Slackware, but for now on to some other installations….
