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

As I mentioned in Slackware Diary, I installed Free42 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 – 2

Continuing from Slackware Diary – 1

Fixed the prompt by copying .bashrc and .profile (renamed as .bash_profile) from my primary Ubuntu system. This works and I have nice color prompts in Slackware. Need to see if I have scripts from my previous Slackware days to add environment variables, aliases, etc. Life in Slackware means a lot of time on the command line.

The next task on my list was to install Flatpak so I could use apps from Flathub

Installing Slackware 15.0

Back in February I looked at the Slackware Linux web site. After years of working with Ubuntu, and occasionally its parent Debian, I decided to see if I could install Slackware and get it to work. I used it a lot in the first years of the current century. Could I still manage it now, or had the comforts of the Ubuntu installation process dulled my edge? From Slackware 15 – The old brigade:

Slackware is deployed using an ncurses interface, with a set of menus where you must make intelligent choices, including partitioning and package selection. And then, there’s LILO the bootloader. Not GRUB, mind! Feels a bit daunting, but then, if you’re careful and methodical, there should be no issues. That said, the approach automatically precludes Slackware from being a typical desktop choice, as most people would have no idea what to do with the installer.

More about Zoom under Windows

As I wrote in September, my HP EliteDesk 705 G2 SFF desktop with an AMD PRO A4-8350B R5 processor was giving me messages about limited computer resources when using Zoom under Windows 10, though not under Linux. These sitll occur, even though I have added memory, taking it from 8GB to 24GB. This last time, I finally remembered to bring up Task Manager. It showed me that there was no memory problem, but that Zoom was using a lot of CPU. Why this occurs with Windows but not Linux is puzzling. For now I will have to have all of my Zoom sessions on that system under Linux rather than Windows.

More Storage Upgrades

I got a new 1TB SSD drive for Christmas. I used it to replace the 512GB drive that I had installed on my HP EliteDesk 705 G2 SFF system. That 512GB drive in turn went back to the old laptop I had taken it from. In both cases the copying was done by Macrium Reflect Free. There were no problems at all with the HP desktop, but the laptop refused to boot afterwards. So I got out my Linux USB boot repair stick and booted from that, ran the boot repair utility and everything was fine. Both Windows 10 and Ubuntu Linux 20.04 booted cleanly.

So I now have two extra 256GB SSD drives. Don’t really know what I will do with them. For now they are mounted in enclosures with USD 3.x connections.
