In October, my Dad and I got to go behind the scenes at two St. Louis Blues (NHL hockey) games, and observe the massive team effort involved in putting together a modern digital sports broadcast.
I wanted to explore the timing and digital side of a modern SMPTE 2110 mobile unit, and my Dad has been involved in studio and live broadcast for decades, so he enjoyed the experience as the engineer not on duty!

Ever since the Raspberry Pi Compute Module 5 was introduced, I wondered why nobody built a decent laptop chassis around it.
You could swap out a low spec CM5 for a higher spec, and get an instant computer upgrade. Or, assuming a CM6 comes out someday in the same form factor, the laptop chassis could get an entirely new life with that upgrade.

Recently this post from @Merocle caught my eye:
I'm fixing my iFixit soldering station. I haven't used it for a long time and the battery has gone overdischarge. I hope it will come back to life. Unfortunately, there are no replacements available for sale at the moment.
Devices with built-in rechargeable batteries have been bugging me a lot lately. It's convenient to have a device you can take with you and use anywhere. And with modern Li-ion cells, battery life is remarkable.

A few weeks ago, I started hearing a slight crackle at the loudest parts of whenever sound was playing through my PreSonus Eris E3.5 speakers. It was very faint, but quite annoying, especially when editing my YouTube videos.
For a few days I thought it could be a hearing problem (at this point in my life, every year brings a new health adventure...), but after testing my wired headphones and another small computer speaker on the same output, I determined the problem was, indeed, coming from the PreSonus speakers.

After 16 years on the LAMP stack, I finished migrating this website from Drupal to Hugo a few weeks ago.
What's old is new, as this blog was originally built with Thingamablog, a Java-based Static Site Generator (SSG) I ran on my Mac to generate HTML and FTP it up to my first webserver (over 20 years ago!).
The main reason I moved from an SSG to Drupal was to add comments. I wanted my blog to have the same level of interactivity I had pre-Thingamablog, when I was (briefly) on Xanga.com.

Today Raspberry Pi launched their new $130 AI HAT+ 2 which includes a Hailo 10H and 8 GB of LPDDR4X RAM.
With that, the Hailo 10H is capable of running LLMs entirely standalone, freeing the Pi's CPU and system RAM for other tasks. The chip runs at a maximum of 3W, with 40 TOPS of INT8 NPU inference performance in addition to the equivalent 26 TOPS INT4 machine vision performance on the earlier AI HAT with Hailo 8.
