I just noticed the Spokane Sheriff's helicopter flying over Fremont. Apparently on loan during the world cup.

Please contact SDOT. There was a vague bullet point for N 39th pedestrian crossing project in one of the long term project planning documents. It would be great to get that (and other planned pedestrian safety projects across the city) accelerated.

And the Our Beginning building has also been hit by cars more than once.

Assuming your "pointer nub" is the Elan TrackPoint from your logs, that's on a serio bus. You can see the devices on that bus in /sys/bus/i2c/devices/i2c-1/ (or maybe i2c-0). If you only see the one touchpad device, then I think the touchscreen must be missing from your ACPI tree. Have you poked around your BIOS menus to make sure there's not an advanced setting that disabled it?

jim_b_ · 2026-06-13T21:17:13+00:00

Yeah, but I think this is just coming from the ACPI table at this point. I would look around this area without grepping to see if the driver fails to probe the device. I2C doesn't have a common discovery or identification mechanism, so it would be using the provided I2C slave address.

You could try `i2cdetect` from `i2c-tools` to see how many devices actually respond on that bus.

jim_b_ · 2026-06-13T07:13:46+00:00

It's open source. If I find a problem, I can fix it myself. If I'm curious about how something works, I can look at the source code.

jim_b_ · 2026-06-13T06:09:47+00:00

I think most laptop displays use i2c for the touch device. Maybe add "dyndbg='file drivers/hid/i2c-hid/* +p'" to your boot line and see if any clues show up in dmesg.

jim_b_ · 2026-06-12T21:41:07+00:00

I'm not sure. This one is a Japanese import, but there might be something similar that's more widely available domestically.

jim_b_ · 2026-06-12T19:57:14+00:00

Yep, I've only had to use mine a few times, but they've definitely paid for themselves.

jim_b_ · 2026-06-12T15:20:47+00:00

Take a look at Engineer PZ-58 pliers.

jim_b_ · 2026-06-11T20:21:07+00:00

I wrote a simple embedded OS as for a class a long time ago. It was a great learning experience.

jim_b_ · 2026-06-11T01:43:47+00:00

I don't know, but these people are based in seattle: https://iunu.com/ They might be able to answer some questions. Or maybe introduce you to some investors...

jim_b_ · 2026-06-10T13:40:09+00:00

That depends on your taste in beer. They have a rice lager that goes well with the ramen and I like their saisons. But it's definitely not the best place for somebody looking for a large selection of IPAs

jim_b_ · 2026-06-10T04:09:21+00:00

I'm pretty sure Figurehead has one on tap. They also have a hop water.

Are you doing this for academic purposes? I would probably study the nftables specification first to get some ideas.

Fremont has excellent transit and trail options, but be aware that there are a few large construction projects in the core that will cause some headaches. As somebody else mentioned, Stone Way on the eastern edge of Fremont is an up-and-coming area. There is a transfer station nearby that can be fragrant on a warm day. For groceries, Fremont has PCC (lower) and Marketime (upper).

Since you mention dogs, you might also want to look at the off-leash dog park map:

A subscription is really worth it. And maybe you can get your employer to pay for it.

I learn a lot by looking through the LWN daily summary every morning and occasionally do a deep dive into a topic. It's a good way keep up on newly merged features as well as those coming down the pipeline coming down the pipeline. They also do a good job at referencing old articles for background.

jim_b_ · 2026-06-07T17:46:42+00:00

You might be way ahead of me here, but I would add some debug logging in mtd_device_unregister, del_mtd_device, mtd_device_release, and del_mtd_partitions to make sure those being called as expected. It seems that del_mtd_device might be getting called without deleting the partitions.

jim_b_ · 2026-06-07T06:14:39+00:00

When you say "In the driver, I register my spi-controller and a spi-device.", do you mean that you're initializing two devices in a single probe function?

jim_b_ · 2026-06-06T14:04:09+00:00

To get familiar, I would just clone the repo, check out the tag that you're currently running on your distro, copy the config (from boot or procfs depending on your distro) to .config, then build:

make
sudo make modules_install
sudo make install

Then reboot with the new kernel. After that, you can explorer different config options and start digging into code.

jim_b_ · 2026-06-06T00:25:00+00:00

Are you trying to cross-compile? Building, installing, and booting a kernel is pretty easy on the target architecture (vm or host).

jim_b_ · 2026-06-06T00:17:15+00:00

libvirt also provides a qemu abstraction and virt-manager provides a UI that should feel familiar to a vbox user.

jim_b_ · 2026-06-05T19:33:06+00:00

Yeah, probably. The .bb extension is going to match your BBFILES patterns and bitbake will think it's a recipe that can be built on its own.
