Any tips on how to read and interpret the output from the umr utility to monitor the user mode registers?

I am trying to determine the bottleneck in my compute shader.

I just upgraded to 26.04 and I can no longer use vulkan?

$ sudo vulkaninfo
ERROR: [Loader Message] Code 0 : vkCreateInstance: Found no drivers!
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.

I use a Radeon RX 7600, and the kernel driver has been found:

I made a thing. It can record movies in colour.

I took my home-built camera out into the street to shoot footage of this bus with an ultra thin DoF.

Lens is from an old episcope: Pentacon 3.6 : 420mm. It sounds long, but this lens is actual normal angle on my camera, considering the 34x34cm ultra large format.

Quite a unique look, and I think I nailed the focus on the bus.

I wanted to share what footage is possible with an extreme camera setup.

My camera build was inspired by Zev Hoover, look him up if you want to learn more about LF filming.

Available light only, with sun rather low, roughly in my back. (Straight from camera, no edits other than flipping the image right side up.)

Let me know what you think of this look.

I have:

TP-Link EAP683 UR | Omada WiFi 6 AX6000 Wireless 2.5G Ceiling Mount Access Point

I would like to connect a device using WPS to it.

Can this access point do WPS? I don’t see a button for it on the device.

I saw GOU #3 Mercedes drive w high beams on, unlike his competitors.

Which makes me wonder… do high beams on, make the alternator take more engine power away?

I intend to get two wifi access points, and set them to the same ssid, same password, different channel, both in bridge mode.

Will my iPhone be smart enough to switch when I walk from downstairs to upstairs of my home?

Should I get wifi7 for this, or wifi6?

All the routing should be left to my separate home router, which is connected to my ISP’s fibre with 1gbps.

I want my devices to be able to roam, and get good signal on both floors, or maybe even three floors if I do the basement as well.
