I can’t get my heart rate up on the bike, even when I feel I’m pushing hard. I grind up hills, spin through flats, and yet it’s hard to get above 120–130 bpm. I run at 160 bpm and race at 170-180. Cycling is a very muscle‑specific sport. Unlike running, where your whole body (and the … Read more
(warning: I’m not trying here to explain something to folks outside computer science, but more summarize something awesome I’m learning that is changing how I write code) As software systems grow increasingly complex and automated, ensuring correctness becomes a monumental challenge. In a future of automatically generated code, certainty is both elusive and critical. Enter … Read more
Hello Gemini Robotics! Google surprised me a couple weeks ago with some cool tech. I’m watching carefully for the events that get AI into hardware and Vision Language Action has a lot of promise in creating more general and adaptable robots. It’s a good name — intelligence that integrates vision, language, and action—allowing robots to … Read more
Training for a Half Ironman (70.3) is equal parts endurance, nutrition, and smart pacing. Over the last few months, I’ve spent countless hours in the pool (plus on the bike and run) to prepare. Below is the nutrition and timing strategy I’m trying out for race day. I normally like to show my work, but … Read more
Aging makes running harder: recovery slows, endurance wanes, and managing weight is tougher. Stress from increased work responsibilities compounds these challenges. My last job pushed my stress levels high, prompting me to seek relief through distance running—a hardship chosen and controlled, providing a welcome contrast to life’s uncontrollable demands. In that spirit, I did a … Read more
I manage my own webserver via docker and have a wordpress blog for each of my kids (eg lauren.theboohers.org) Yea dad! Well, I noticed that loading my son’s blog (david.theboohers.org) would occasionally redirect. I’m sharing how I dealt with this so you might save some time and pain. What is the problem? Over the past … Read more
My son was jumping around the neighborhood on his 2019 Men’s Stumpjumper ST Comp Alloy 29 and noticed his chain sticking on the back of his bike. He was jumping around and noticed that the rear gears and chain were binding. You can see this below: I took off the derailleur and noticed the notch … Read more
One of the coolest challenges in robotics is to enabling machines to grasp the bigger picture from a small bit of human control. Imagine an operator guiding a single robot in a complex environment—the robot isn’t just executing isolated commands, but is part of a larger, dynamic mission. This is where multi-agent goal inference steps … Read more
You can’t build anything big and important without a solid foundation. In security, hardware acts as that unyielding foundation, the basis for all other defenses. While fancy encryption and zero-trust principles can safeguard data in an environment where software is inherently untrusted, they ultimately rely on hardware’s immutable security properties. Companies are partnering with cloud … Read more
Tracking and categorizing financial transactions can be tedious, especially when it comes to Amazon orders. With Amazon’s new data policies, it’s harder than ever to retrieve detailed purchase information in a usable format. Amazon is so broad that a credit card charge could be for a digital or physical product, a whole foods purchase. The … Read more
