openSUSE zen-updater crashes

-
Today is the 2nd time I have encountered zen-updater crashes that shows the "Unhandled exception" dialog.
After a little googling, I found the solution here http://en.opensuse.org/Using_zen-updater#Why_zen-updater_crashes
Basically, it says that the zenworks database is corrupted and one way to fix it is to:
  1. kill the zmd and zen-updater processes
  2. delete the database at /var/lib/zmd/zmd.db
  3. restart zenworks and zen-updater.
For more details, please refer to the link above.

Repairing Roomba charging circuit

-
Image
Sometime ago, a colleague told me that she bought a Roomba 405 but the battery seems dead, unable to charge. Being the curious me and how I like to fix things, I made a deal that if I could fix it, I can use it to clean my house for 1 month :-) So, this post is a sharing and also a kind of documentation for myself on how I got the Roomba working again. Initial diagnosis.... So, the next day she brought the Roomba to me in office and I took it home. First step, I tried to charge it by connecting the AC-DC adapter to the robot. According to the user manual, it seems charging. The amber LED is blinking slowly. A few hours later, I detached the power and try to see if it moves by pressing the "Clean" button. Nope, it is dead as a log. So, next step, I took my multimeter, removed the battery and measured the battery terminal voltage. Huh, it reads approx 0.6V? Now, I gotta monitor the voltages while charging to figure out what's wrong. I attached 2 thin wires to the terminals,...

OpenCL on Ubuntu 24.04 with open source drivers only

-
Running OpenCL on Linux with older AMD GPU (not supported by ROCm) has been mostly disappointing. Recently, I've stumbled upon Rusticl which an OpenCL implementation on Mesa Galium driver. However, my current Ubuntu 24.04 does not come with latest mesa packages and I'd prefer to not install kisak-mesa PPA which can sometimes mess up the system when upgrading Ubuntu. It seems that Fedora comes with latest Mesa packages with rusticl enabled and I found this blog describing how to install the required packages: https://nullr0ute.com/2023/12/getting-started-with-opencl-using-mesa-rusticl/ Based on that, I've found a way to use OpenCL with rusticl within podman/docker container. Here's the Dockerfile: FROM fedora ENV RUSTICL_ENABLE=radeonsi ENV http_proxy=http://192.168.0.130:3128/ RUN dnf install -y mesa-libOpenCL mesa-dri-drivers spirv-llvm-translator spirv-tools-libs clinfo clpeak RUN cd /root && \     curl -L https://cdn.geekbench.com/Geekbench-6.3.0-Linux.tar....

It's a monster and it's a 12cm, 12V DC Fan!

-
I have just got a 12cm fan from my company's scrap parts. It is a poweful fan that I have just installed in computer. To do that I know a Dremel would be a great tool for case mod like this but I don't have one. Using a hacksaw, a plier and a set of files, I was able to cut a hole at the top of the casing and installed the fan. It wasn't great, but it works. I can't post any picture yet as I don't have a camera with me now and my camera phone was stolen :( Because the fan is so powerful, when it is powered at full speed, it will suck so much air out of the casing that it interrupted the air flow into the PSU. Therefore, I'll need to build a PWM controller circuit to control the fan speed.
