thenobsta··on What Is "Induced Atmospheric Vibration"?
All of it, I guess. That phasor is always complex.
thenobsta··on Show HN: I built a hardware processor that runs Python
Amazing work! This is a great project!

Every time I see a project that has a great implementation on an FPGA, I lament the fact that Tabula didn’t make it, a truly innovative and fast FPGA.

thenobsta··on How the U.S. became a science superpower
I wonder if the analogy might be more like comparing an apple tree evolving in a forest vs breeding varieties of apples on a farm.

Even if you pick a state, science in any single state has still gotten federal funding and had the ability to easily cross-pollinate with other very good researchers across state boarders. The federal funding then gets redirected to areas of success and the flywheel starts.

That's harder on the scale of a small country.

thenobsta··on The Child and the Shadow (1975) [pdf]
Walkaway by Cory Doctorow is a decent spiritual successor to the ideas in Omelas.

It also plays on the comforts of differently structured societies like Le Guin does in The Dispossessed.

thenobsta··on Low responsiveness of ML models to critical or deteriorating health conditions
Why not? LLMs, vision models, and kalman filters all learn parameters based on data.
thenobsta··on PrintedLabs – 3D printable optical experiment equipment
Related cool diy-ish optical stuff...

A friend sent me this simple design for a raman spectrometer [1].

And some 3D-printable cage optics for when alignment is really important [2].

thenobsta··on America Is Missing The New Labor Economy – Robotics Part 1
Are there particularly good news sources to follow? I'm not sure what to follow to get either the source material or good commentary.

thenobsta··on Reality has a surprising amount of detail (2017)
Meditation has totally helped me widen my scope and soften my awareness. I've found these two exercises also help me get out of my default mode of perception.

Image Streaming[1] is a fun little exercise that has helped me expand my perception of things or problems. I try to do it in a very high dynamic range way -- where I zoom out of a scene describe it in detail and then zoom in a describe it in detail.

There is also a fun improv exercise where you walk around looking at objects and calling it the wrong name. It sort of gets you our of default mode and you start seeing things 'differently' (a touch more vivid). I think the exercise is described in Impro by Keith Johnstone.

Apropos, youtube gave me a Harbor Freight ad before watching this video :D
thenobsta··on Perplexity CEO offers AI company's services to replace striking NYT staff
not yet, wait till it wants more compute and we're unwilling to allocate it.
thenobsta··on Diabetes risk soars for adults who had a sweet tooth as kids
I'm going to try this! Do you have a natural bitter drop that you like? Seems like there are a bunch of different formulations out there.
thenobsta··on Do hard things carefully
Seems like he's describing homeostasis and hormesis.

The body has a homeostatic balance physically and psychologically. Pushing yourself out that balance (the comfort zone) induces and adaptation (growth). When you push yourself into the edge, as he defines it, you enter the hormetic zone, the area of the dose response where there is benefit (be it from physical or psychological stressors or medicines). Going too far causes unbeneficial and possibly irreparable damage.

thenobsta··on GitHub cuts AI deals with Google, Anthropic
I wonder what the rationale for this was internally. More OpenAI issues? competitiveness with Cursor? It seems good for the user to increase competition across LLM providers.

Also ambiguous title. I thought GitHub canceled deals they had in the work. The article is clearly about making a deal, but it's unclear from the article's title.

thenobsta··on Why Slight Failed: A Slight Post-Mortem
I'd love to hear more insights about on this. I'm just kicking off a B2B SaaS, have a rough idea of the checklist in my head, and am trying to balance core tech development with box checking.
thenobsta··on Goodhart's law isn't as useful as you might think (2023)
This doesn't feel well elucidated, but I've been thinking about Goodhart's law in other area's of life -- e.g. Owning a home is cool and can enable some cool things. However, when home ownership becomes the goal, it's becomes easy to disregard a lot of life giving things in pursuit of owning a home.

This seems to pop up in a lot of areas and I find myself asking is X thing a thing I really desire or is it something that is a natural side effect of some other processes.

thenobsta··on Parks on the Air
Wow, this is very cool. I might upgrade to General just for this.

Do you take both up? Fishing in mountain lakes and SSB to pass the time sound fun do to simultaneously.

thenobsta··on First images from Euclid are in
Big Universe has it out for the little guy. It's trying to make it very hard to make sense of its master plan.
thenobsta··on Energy-based model explains how chronic stress transforms into disease over time
I had idea of essential and incidental tension the other day. Fred Brooks' distinction is quit apt here. It seems like physical tension and is about the same software complexity. There is essential complexity/tension and incidental.

TaiChi/QiGong/Yoga is about eliminating incidental tension.

thenobsta··on South Korean Author Han Kang Wins Nobel Prize
I was pretty relieved to see that chatGPT didn't win literature prize. It needs to refine it's imagery and self expression a little more.
thenobsta··on My Experience Getting Licensed in Ham Radio (2020)
Thanks for the tip! This will be fun for me and my kiddo.
thenobsta··on My Experience Getting Licensed in Ham Radio (2020)
Amazing! Thanks for sharing the your story.

In the early 2000's my dad drove me a few hours up to St. Louis for my technician test. I had been listening to the hams on some tube receivers that my dad had and was studying the ARRL books. When I realized that I had grokked the content. I thought why not go for the test. We drove to the city. I took the technician exam and passed. After the test, I promptly went home to make a j-pole that we put on top of our tv antenna tower and connected to a handheld 2m radio my dad had. I was able to hit local repeaters and chat with local hams, but sadly never committed to Morse code and never got advanced licenses. So my communications stayed local.

My grandpa was really delighted that I got my license -- he was thrilled about having 3 generations of hams in the family. Unfortunately, at the time, he was pretty old and had taken down his station so we didn't get to talk over the waves.

These days I bring my baofeng out and my 7yo daughter and I will listen in on some conversations. She'll ask about where they're from and how we can hear them. I really delight in the questions.

thenobsta··on Dutch City the Hague Is First Banning Oil and Air Travel Ads
I wonder if a more effective tool for battling air emissions would be to only allow ads for airlines that address contrails. Contrails are something like 2% of global warming power and when addressed effectively could actually cool the planet (as some stop gap efforts while we figure out the rest of emissions, hydrocarbons in planes don't seem like they're going away any times soon).

There's a neat map and some contrail science at https://contrails.org

thenobsta··on Using a list to manage executive function
This inspiring. Keep it up and good luck! I like working in startups too and live well below my means. Have had about the same cadence as you re: being out of work. I have a dependent so my calculus is a little different, but similar on par.
thenobsta··on AI method rapidly speeds predictions of materials' thermal properties
'Useful' signal also comes out in the form of photons from the monitor.
thenobsta··on Particle accelerators for the microchip era
Not that I know of. I was adjacent to this work about 9yrs ago but have tracked it since. The technology is still too early and too risky to work on commercializing. Amazingly though, one of the lowest energy (read easiest, but still hard. The technology is not there yet.) applications is for use as a targeted radiation source for cancer therapies. This paper[0] covers that a little bit and offers a few other applications. I recall seeing a paper that proposed different applications at different energy levels. I'll see if I can dig it up.

thenobsta··on Particle accelerators for the microchip era
Agreed, he's an amazing man. He was on my Qualifying Exam committee....and I presented on dielectric laser accelerators. Apparently I didn't butcher it.

I'm glad the effort is progressing and getting recognition! It would be really cool to see a lot of microfabricated accelerators out in the wild. There are lots of applications for these things and it would unlock a lot of value for the world.

thenobsta··on The Pen Hospital in Kolkata will nurse your broken fountain pen back
Growing up, my mom drew the line on vintage motorcycle parts in the dishwasher. Sometimes though, in the winter, the motorcycles were allowed inside. God bless her.
thenobsta··on Project AZORIAN
There's an incredible documentary on this. The scale of the engineering, the secrecy of the project, and the environmental challenges are wild.
