Second this. I don't think most people on hn understand how powerful he is.

My version of this was a 10-week discrete RF circuits course in graduate school. We had to build a fully functional GHz transceiver out of small FR4 PCBs (< quarter wavelength) and…

This is terrifying. Our ability to think has been our biggest differentiator as a species. LLMs threaten this, and I'll die on that hill.

There are chip startups trying to address this exact issue. For example, Cornami: https://cornami.com . There is also a lot of research into lowering the power/compute penalty of F…

From my experience on this, the single biggest determining factor on one's opinion is whether you have kids (I have elementary-age kids). We have to work like mad to limit screens,…

I second that. 3b1b is fantastic for developing a more intuitive understanding of mathematics. In my experience, having that intuition makes all the difference.

Did you ride the Great Allegheny Passage?

Chipset developers like Silicon Labs* are developing very advanced but approachable security capabilities into their latest products (secure boot, secure debug, physical protection…

This reminds me of a great film on crafting quartz crystals for use in radios: https://youtu.be/wHenisSTUQY

Yup, it can get hot in the summer. On the flip side, winters are great! The best time of year is Mar/Apr and Oct/Nov. Absolutely gorgeous. There's a reason why SXSW and ACL are sch…

I am from Texas and currently live in Austin, but I also had the opportunity to live in many places in the world (Bay Area, China, Singapore, and Norway) spread out over a decade. …

I lived in Shenzhen from 2007-2011 and can confirm that large amounts of recyclables were shipped to China. Open-air facilities hired pickers to go through the material and pull ou…

Thank you, I purchased the book!

Thanks, I will start there!

I am looking to get started with d3 (https://d3js.org/). What is the best way to do this?

You might check out the EFR32BG22 from Silicon Labs. It has alot of great security functions, including a dedicated security core with secure boot, secure debug, and unique ID.

I have all the respect in the world for what Mr. Musk has accomplished, but it has come at an amazing cost to the people around him. He is worshiped from afar but reviled by many t…

Good questions. His techniques rely on building a relationship, empathy, and many other techniques. If you enter the process with a split the difference mentality, you invariably l…

I highly recommend reading Never Split the Difference, by Chris Voss. The book offers a different take to negotiation, written by a former FBI negotiator. In his words, he could ne…

Having spent my entire career in the chip industry designing and defining chips, I'm still amazed year after year.
