by Hugo Barra (former Head of Oculus at Meta) Friends and colleagues have been asking me to share my perspective on the Apple Vision Pro as a product. Inspired by my dear friend Matt Mullenweg̵…
What if everyone could do robotics? That would be great, right? We should make a software framework so that non-roboticists can program robots.This idea is so close to a correct idea that it's hard to tell why it's a mistake.
I’ve had the curiosity to explore radio communication protocols for a few years now, ever since I’ve started fiddling around with an RTL-SDR dongle. I always had the goal of figuring out how data is transmitted in remote controls (car key fobs particularly), trying replay attacks, and other possible attack vectors.
Silicon lottery. Now that the Raspberry Pi 5s been readily available (at least in most regions) for a few months, more people started messing with clocks, trying to get the most speed possible out of their Pi 5s. Unlike the Pi 4, the Pi 5 is typically comfortable at 2.6 or even 2.8 GHz, and some Pi 5s can hit 3.0 GHz…
A famous blockprint by Hokusai titled “Mount Fuji Seen from the Mountains of Totomi,” showing a crew of sawyers rip-sawing a timber into boards using maebiki ooga saws, one man on top a…
Improving the performance of a PC cooling system by writing a custom control loop in Python, and monitoring the results with Grafana.
A few months ago I introduced you to one of the more notable Apple pre-production units in my collection, a late prototype Macintosh Porta...
Malcolm has analyzed the Finnish 1992 sauna ventilation study profile to improve sauna ventilation in his own backyard sauna.
Revision 4 is the new version of the Starlink user terminal. As of February 2024, the new version is only available in the US. I decided to test the new hardware and compare it to the well-known REV3 (a.k.a. Gen2/V2 or “Standard Actuated”).
Today, I’m going to write a bit about our GPU cluster machine we call cogito at Driveline Baseball. I’m going to timebox these blog posts so I get them out and also save my sanity, so t…
Welcome to the blog. As a way to kick things off, here’s a single-page version of my thread on the F-35C tailhook.
Despite otherwise seeming to work correctly, I can't monitor a Back-UPS BX1600MI in Linux without seeing a constant stream of spurious battery detach/reattach and power fail/restore events that last less than 2 seconds each. I've tried multiple computers and multiple UPSes of that model. It doesn't happen in their own…

Enabling and using xDCI controller on ThinkPad X1 Carbon 6th Gen
A couple of years ago, I was in an incident that reduced the strength in my left shoulder. I’ve been waiting for an operation to restore the function to that shoulder, but we were warned the post-operative recovery period would be several months. So I started looking for keyboard options...
INTRO: The output Impedance of headphone sources is one of the most common reasons the same headphones can sound different depending on wha...
Keeping a Raspberry Pi online and working with zero intervention for weeks, months, or years is somewhat of an art form. Several classes of things can go wrong, and you need to consider how your Pi will recover from each of them.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Extract metrics from your GoodWe solar PV system, and improve its security too
For years, the M1 has only supported OpenGL 4.1. That changes today – with our release of full OpenGL® 4.6 and OpenGL® ES 3.2! Install Fedora for the latest M1/M2-series drivers.
Symbolic of the transfer of power from IBM to Microsoft?
This cube manages to balance itself on a corner, and can simultaneously rotate around its axis in a controlled manner. It does so using clever controls and a set of three reaction wheels.
I am trying to capture “through the optics” pictures of the AVP, and it is unveiling both interesting information on how the AVP works and the second test pattern I tried “broke&#…
Getting 'low level' with Nvidia and AMD GPUs
The Apple Vision Pro is a disappointment for productivity, in part because of choices made to deliver a remarkable entertainment experience. Plus, the future of AR/VR for Apple and Meta.
Just as the AGBT hype cycle was firing up (with me contributing multiple sparks), serial entrepreneur Jonathan Rothberg's latest sequencing ...
I'm currently typing this blog post in a floating window in the middle of snow-covered Yosemite. I am a floating body manifested into the transcendental Tim Cook matrix. I look into the sky and follow the soft clouds as they pass overhead. They slowly part, revealing Steve Jobs' smiling face watching over me from the…
