The sea, if it teaches nothing else, does at least compel a submission to the inevitable; which resembles patience.

jpm_sd··on Lost Silk Road Cities Discovered High in the Mountains of Central Asia

Modern historians are now pretty sure there never was a "Silk Road"

jpm_sd··on Ask HN: How do you organize your electronic components?

You don't have to keep everything. Decide which parts are too cheap and easily replaceable to bother with, and throw them out.

Pre made resistor and capacitor kits are a nice way to keep a selection on hand that's pre-organized for you.

Lots of people are suggesting 3D printed bins but I'd recommend something anti-static, for example:

jpm_sd··on Show HN: I 3D scanned the tunnels inside the Maya Pyramid Temples at Copan

It's called "social media"

jpm_sd··on Turn your Android phone into a modern ham radio transceiver

Very neat project. How are you dealing with FCC certification?

jpm_sd··on The Remarkable Life of Ibelin

I didn't find it bleak at all. Brought tears to my eyes though.

I'm glad your condition is less severe, or better managed, than his. Keep living your best life!

jpm_sd··on Civilization VII recommends 16 cores and 32GB RAM for 4K gameplay

Yeah but look at these graphics. The term "cinematic" is overused but wow. https://www.youtube.com/watch?v=Tc3_EO6Bj2M

I put hundreds of hours into the original Civilzation and Civ2 but I haven't played in years. This might actually draw me back in.

jpm_sd··on Why does man print "gimme gimme gimme" at 00:30? (2017)

I like the way you phrased this. Maybe someday academics will refer to Bullock's net the same way we talk about Occam's razor, or Maxwell's demon, today.

jpm_sd··on Manna – Two Views of Humanity's Future (2003)

(2003)

This is 20yr old and wasn't that good in the first place. Star Trek and Iain Banks did it better IMHO

jpm_sd··on Cooking items in your home are linked to cancer-causing chemicals

Replace your plastic utensils and delicate nonstick cookware with metal spatulas, wooden spoons and cast iron pans. Problem solved!

jpm_sd··on TSMC execs allegedly dismissed OpenAI CEO Sam Altman as 'podcasting bro'

At this point it's become clear that Sam Altman is an Emissary of the Eschaton (in the Strossian sense)

jpm_sd··on Octopuses seen hunting together with fish

I can't wait for OctoPunch, the turn-based combat video game! You play as the octopus, of course, and build your party from a selection of fishy characters, each with their own personality and special hunting skills.

jpm_sd··on Jetstream: Shrinking the AT Protocol Firehose by >99%

"those things" meaning the all-new Iridium constellation, launched in the late 2010s?

jpm_sd··on Jetstream: Shrinking the AT Protocol Firehose by >99%

Iridium satellite modems too.

jpm_sd··on A lonely man in his 30s found welcome and community at spin class

I go for long solo bike rides pretty frequently, have done some group rides from time to time. I've met a few genuinely friendly people and a lot of passive-aggressive gear snobs.

jpm_sd··on Tell HN: Burnout is bad to your brain, take care

Getting a new job at a big, slow moving company can be a good way to recover while not becoming destitute

jpm_sd··on Origami-Inspired Phased Arrays Are Reshaping the Future of Antennas

This is extremely academic. Reinventing flex circuits on a 3D printer??

AFAICT they built exactly one "unit cell" and there's no way that SPI interconnect scales to an array

jpm_sd··on One Laptop per Child

As has been widely publicized, this project was a total[0] failure[1]. Can anyone from the "developing world" <eyeroll emoji> comment on what has succeeded in its place? Mobile phones? Chromebooks?

Here in Massachusetts, USA we're on the One Chromebook Per Child plan. Seems to mostly work OK.

jpm_sd··on Ethernet History Deepdive – Why Do We Have Different Frame Types?

I think this is a terrible idea. Daisy chain multi drop is so last century. Switched point to point networks are so much better!

jpm_sd··on New doctoral thesis proposes Buckminster Fuller was a 'charlatan'

Today, he would be either a Silicon Valley VC investor or living in a homeless encampment in Oakland.

jpm_sd··on Share of total health spending, by percentile

https://www.healthsystemtracker.org/chart-collection/health-...

Don't assume high spending necessarily means poor overall health. Two people in my household are on modern fancy drugs for autoimmune conditions (upadacitinib and etanercept). They work spectacularly well and cost our insurance company thousands of dollars a month. And the family members taking them are doing great!

jpm_sd··on Ask HN: What does RISC-V custom chips for under $100K mean?

I took a look at your blog[0]. You aren't going to need a custom CPU. You'll be much better off with something that's already in production, in the market, well-documented and well-tested. Also it sounds like you have a pretty steep learning curve ahead of you.

jpm_sd··on Show HN: After 2 months my project management software is finally finished

Yep, 2 months is "I've almost started"... Anyway, once people actually begin using it, the real work begins.

jpm_sd··on Sam Altman is not on YC's board. So why claim to be its chair?

Sam Altman is a pathological liar

jpm_sd··on First look at the upcoming Starlink Mini

Don't assume a conspiracy where the underlying mathematics are a sufficient explanation! Centralized systems use RF bandwidth MUCH more efficiently.
