Raley's on Freeport
by Brian E. Lavender 18 Jan '26

18 Jan '26

Future meeting location ideas. Does anyone hang out at the Raley's on the Freeport? They have the mezzanine area. I was thinking we could do a social there. I realized that I could actually bring another monitor and plug it into my system. That way we could just have people on both sides of the table. -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

January Meeting
by Brian E. Lavender 11 Jan '26

11 Jan '26

January General Meeting We will continue at Kupros for January. If anyone has a different location in mind for February, please let me know. https://www.saclug.org/articles/2026/january-2026.html When: Tue January 20, 2026 06:30 PM to 08:30 PM Speaker: You Location: Kupros We will meet back at Kupros for this meeting! The last meeting we had, some noted that it was too loud. I had been thinking about a different location, but I didn’t investigate, so we will continue at Kupros for now. Bring your gadgets, laptop, etc., and we will discuss, evangelize and strategize the upcoming meetings. We usually congregate on the second floor. Look for a penguin printout or hackers with their laptops open. Brian -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

btrfs subvolumes
by Brian E. Lavender 17 Dec '25

17 Dec '25

We were discussing separate partitions for / and /home in an installation and I noticed that my two separate partitions shared the same space. btrfs to the rescue! https://fedoramagazine.org/working-with-btrfs-subvolumes/ So where do the home and root subvolumes in Fedora Linux come from? These are created by the installer at install time. Traditional installations would often include a separate filesystem partition for the / and /home directories. During boot, these are then appropriately mounted to assemble one full filesystem. But there is an issue with this approach: Unless you use technologies such as lvm, it is very hard to change a partitions size at some point in the future. As a consequence you may end up in a situation where either your / or /home runs out of space, while the respective other partition has lots of unused, free space left. Since Btrfs subvolumes are all part of the same filesystem, they will share the space that the underlying filesystem offers. Remember when we created the subvolumes above? We never told Btrfs how big they are: A subvolume can take up all the space the filesystem has, by default nothing keeps it from doing so. However, we could dynamically impose size limits via Btrfs qgroups, which can also be modified during runtime (And we’ll see how in a later article in this series). -- Brian Lavender https://www.brie.com/brian/ "There are two ways of constructing a software design.

AI news
by Kevin B 06 Dec '25

06 Dec '25

Now that you are all informed about AI due to my presentation! In the news this month there are two AI companies one US bound one from the UK they have released some impressive open source models. One is Mistral from the UK https://mistral.ai/ On Huggingface they have 8 billion parameter model - this fits 8gb GPU memory space by Unsloth https://huggingface.co/collections/unsloth/ministral-3 Another from the US is AllenAi https://allenai.org/olmo Huggingface 8 billion parameter model by Unsloth https://huggingface.co/unsloth/Olmo-3-7B-Instruct-GGUF Why is this cool well for one thing the Chinese Deepseek and Qwen models have been the dominant opensource models to date. What is cool about the Olmo models is not only is the model open source but the training data is too. Huge win for them in regards to transparency From a coding aspect UC Davis allows us to use Chat GPT 5 at work. With Visual Studio Code you run a tool called Codex with Chat GPT. In the last week or so I have automated a bunch of jobs and and deployments with it. Yes, I understand the code, but it does it faster than myself. I'm on a serous automation kick at work. Not only has the tool helped with automation but it helps me understand the code base on how some of these apps work that I have to trouble shoot. Franklin was a great place to work but tough to get anything done. It's been a breath of fresh air working at UC Davis, they let me fix and improve as needed. I feel super productive. I hope everyone had a nice Holiday feast week last week and look forward to seeing you all at the next meetup! Kevin

Wayland and Fedora
by Linus Sphinx 01 Dec '25

01 Dec '25

Has anyone seen it wake up? Just logging in it sits and the mouse cursor dies for 45 seconds, it lags all over the place. Now Fedora and Wayland both suck. Switching to Arch.

something got me thinking about Usenet
by Brian E. Lavender 01 Dec '25

01 Dec '25

I see that Sonic offered Usenet service until 2016 https://sonicstatus.com/2016/09/09/usenet-service-ended/ I haven't connected to a Usenet server for I believe around ten years!
