After mentioning DOS in Programming in Pascal I Downloaded Free DOS1.3 from FreeDOS 1.3. I had previously installed VirtualBox on Ubuntu 22.04 system using Synaptic Package Manager. For the installation I followed How to install FreeDOS on VirtualBox. It seems that I have a later version of VirtualBox than the video, so I did not see exactly what is in the video, but it was close enough. Per the video I used the VDI file type for the VM file. The installation was successful. A couple notes:
Back in 2021 I wrote about APL, a computer language that I used early in my career. I have not used it in the last 30 years, but it is still around.
Recently I read that Apple Just Released Code for Its 40-Year-Old “Lisa” Computer.
Much of the code is written in Pascal, an early programming language dating back to 1970, which was also used for some of the Mac’s early software.
- Under History/Early Modern History added Religion in the Scottish Highlands: 1600-1670. Like other pages under that heading, I wrote it for Clann Tartan‘s newsletter.
- Under Physics and Astronomy added two essays from my old web site:
- Under Miscellaneous, added a short page about UFOs and Extraterrestrials, to replace a dead link in Extraterrestrial Intelligence (Spoiler: I am a skeptic)
I fixed some dead links and made other minor corrections and updates, but did not make any drastic changes in the longer pieces, so their style reflects the times when they were written, years or even decades ago. However, I think they are still relevant to the subjects being discussed.
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
Back in August “I upgraded my Ubuntu 20.04 (Focal Fossa) systems to 22.04.1 (jammy jellyfish).” At that time I noted:
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.
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.
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
- 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.
