After a long journey getting AMD graphics cards working on the Raspberry Pi 5, we finally have a stable patch for the amdgpu Linux kernel driver, and it works on AMD RX 400, 500, 6000, and (current-generation) 7000-series GPUs.

With that, we also have stable Vulkan graphics and compute API support.

When I wrote about getting a Radeon Pro W7700 running on the Pi, I also mentioned AMD is not planning on supporting Arm with their ROCm GPU acceleration framework. At least not anytime soon.

Luckily, the Vulkan SDK can be used in its place, and in some cases even outperforms ROCm—especially on consumer cards where ROCm isn't even supported on x86!

On April 8, there will be a Total Solar Eclipse covering an large swath of the US, offering hundreds of millions of people the opportunity to witness one of the most spectacular displays of our sun.

I wrote two blog posts about the recent 2017 eclipse, as well—check those out:

• Photographing the 2017 Total Solar Eclipse
• DIY threaded solar filter

For this year, I was considering going all-in on a custom Raspberry-Pi-based solar tracking system, recording video and images... but Will Whang already built a custom solar imaging setup that would put anything I build to shame.

Since I've done this four times now... and each time it's just a session of reading the docs, searching the forums, etc. until I get everything configured just so, I thought I'd document how I bring up a new MikroTik switch.

I personally love the CRS309-1G-8S+IN, and have three of them running in my homelab. They're less than $250, with 8 10 Gbps SFP+ ports, a 1 Gbps RJ45 port, and a serial console port.

But the best thing for my home use is they are fanless. Blissful silence, outside of a couple beeps the first time you plug it in.

I recently wrote a post detailing how to set up Drupal 8 on a Raspberry Pi using the Drupal Pi project (the same setup which is currently powering www.pidramble.com!) on the Acquia Developer Center blog: Drupal and the Raspberry Pi.

Hopefully people will find more and more useful ways to use Drupal 8 on the Raspberry Pi for automation, for interactivity, and most of all for fun and experimentation!

One of the first questions I'm asked by those who see the Dramble is, "How do I build my own?" Since I've been asked the question many times, I put together a detailed parts list, and maintain it on the Dramble's project wiki on GitHub: Raspberry Pis and Accessories.

For a little over $400, you can have the exact same setup, with six Raspberry Pi 2s, a network switch, a rack inside which you can mount the Pis, microSD cards for storage, a 6-port USB power supply, and all the required cables and storage!

I've watched a few episodes of 'The Minecraft Project' on YouTube for inspiration, and I occasionally play Minecraft for an hour or two as a diversion (it's like LEGOs on a computer, but much more fun, because there are zombies!).

My humble little Minecraft farm.

One thing I've always liked is The Minecraft Project's look and feel, mostly due to syndicate's use of the DokuCraft Light texture pack. However, getting that texture pack to work along with other mods and patches (especially the automatic tool switcher mod) took some work on my Mac, and I thought I'd post my process for getting everything to work here, for the benefit of others having the same troubles (especially those getting the 'Use the patcher noob' messages where water, lava, etc. are supposed to appear):

Over in the Articles section, I posted a detailed tutorial/guide on how to replace the hard drive inside a 24" Intel iMac with an aluminum enclosure (the process is similar on other aluminum iMacs). It's a rather intricate process, so in addition to a few illustrations, I posted a video of the process on YouTube (it's embedded in the article as well!).
