> All natural uranium today contains 0.720% of U-235. If you were to extract it from the Earth’s crust, or from rocks from the moon or in meteorites, that’s what you would find. But that bit of rock from Oklo contained only 0.717%.

Heh. The garbage web software developer me would have just called it good enough

Would be really interesting to know what the error bars on those figures look like

Per NIST[1], the value is 0.7204% +/- 0.0006%, with the uncertainty representing one standard deviation.

I don’t understand why PSA levels aren’t included as part of the standard blood work done with check ups.

teuobk · 3 months ago

Current evidence is that PSA tests don't actually save lives:

I wish they did, of course. I personally lost a close friend to prostate cancer last year. He was 41 and was, before the cancer, one of the healthiest and most athletic people I knew.

The first inkling he had that anything was wrong was a backache that wouldn't go away; a stage 4 diagnosis ensued. He held on for 21 months from the onset of symptoms before the cancer took him.

For what it's worth, /r/welding seems to think this claim is complete bunk:

"Epochalypse" is a nice coinage. Not a new one either, this 2017 article attributes it to Mikko Hypponen (of F-Secure). https://www.tomsguide.com/us/2038-bug-bh2017,news-25551.html

Goes back at least slightly before that, as I've had 2038epochalypse.com registered since March 2017, but I can't recall whether I thought I was being clever or whether I heard it somewhere else.

SEEKING WORK | Remote (based in Denver, Colorado, USA) EMBEDDED FIRMWARE and HARDWARE

Got an embedded programming or hardware design challenge you need solved? I'll solve it!

15 years of experience consulting, and I've seen it all; for the past decade I've been exclusively consulting independently. Past clients have included companies large and small, with everything from green-field ideas for new products to tricky situations with existing products they needed fixed. Comfortable working under regulatory constraints; many of the projects I've worked on have been medical devices.

C is my bread and butter on the embedded side, and Python is my go-to for developing PC utilities and scripts, but I'm comfortable working in a lot of languages from assembly all the way up to Javascript when needed. I can even patch embedded binaries by hand when needed.

Architectures? Well, these days it's mostly ARM Cortex, but I've done everything from 8051 and 6502 to STM8 to PIC16/24 to all of the modern stuff, plus a handful of really obscure things. Specific chip families that I've dealt with a lot lately include STM32, nRF5x, and PIC16, but again, I've successfully worked with MCUs from ST, Nordic, NXP, SiLabs, Renesas, Atmel, Microchip, and various other vendors.

Super comfy with Linux, though most of my practice is bare-metal or with true RTOSes.

Bespoke drivers need development? No problem. USB, I2C, SPI, CAN? Yup, all of those and more. BLE, LoRa? Expert. Power optimization for battery operation? That's a specialty of mine: I squeeze out every last nanoamp -- and quantify the improvement.

BS in EE. Designing analog and digital circuits, laying out PCBs, bringing up boards, debugging hardware, simulating designs (including EM simulations for antennas, transmission lines, etc.), and consulting on hardware improvements are all no problem. I have an extremely well equipped EE lab bench, including for RF out to 8 GHz, and am very comfortable doing fine-pitch soldering under a microscope as needed.

US citizen, masters from Stanford. Licensed professional engineer (PE) in Colorado.

Feel free to reach out and let's see if there's a good fit. Thanks!

Ultra-fast rise-time pulse generators! Yeah, hardware -- or, hooray, hardware!

A few months back, I got excited about pulse generators that had rise times on the order of 15 to 30 picoseconds. There aren't a lot of those available, and I was curious about what would go into their design. so I decided to build my own. https://voltative.com/pulser

Alternatively carefully curate your social media accounts. My reddit home page is all books and formula 1. I'm quick to hit 'show me less like this' when anything drifts in from the front page.

My Facebook feed is all friends and family who don't discuss politics and ads for nerd shirts. I've purchased a few. It is also easy and effective to hit show me less of this.

I agree about LinkedIn and don't go there unless I'm actively job hunting, something I hope never to do again. I don't feel any bitterness when I see friends and family on FB go on expensive vacations, but I do feel an unhealthy and indefensible jealousy sometimes when I see former coworkers getting new jobs or promotions.

teuobk · 7 months ago

Indeed. I've unsubscribed from all subreddits that have become infested with political content, and I've "unfollowed" all of my acquaintances on Facebook and LinkedIn who post anything political. So much more enjoyable.
