FatActor··on Windows 98 icons are great (2015)
It is common in English to make statements like this that are attempting to assert a general hypothesis, and are not expected to pedantically account for every individual human being.
FatActor··on Common Hall-effect sensor myths (2022)
> calibration uncertainty

What is the uncertainty? I thought you just need to zero each ADC after it stabilizes on boot before powering up the load?

FatActor··on Common Hall-effect sensor myths (2022)
#1 is weird. I would never look at a bipolar sensor with a wide hysteresis and think "latch", but after re-reading it that's totally what it is and makes me rethink my idea of a latch. And here I just thought they were for non-intrusively measuring current.

I remember reading someone (Steve Albini?) who said, paraphrased, "Your musical tastes as an adult were defined when you were 14."
FatActor··on Toxicity in Open Source Discussions
> If you can't ignore negative comments and move on without getting worked up

Expecting everyone to have your opinion is literally entitlement.

Perhaps consider empathizing and addressing the complexities root cause rather than just shrugging it off as, "boys will be boys."

FatActor··on EPA proposes to strengthen air quality standards
Good point.

I guess in that instance--if had to argue--people think by just stepping away from the path of the diesel exhaust solves the problem and don't have to think about it anymore except in the context of "boy that one car sure was polluting."

But I see what you are saying it's like a sort of a collective "shrug" and what's worse some cynics well say something I find absolutely idiotic: "Well, everything causes cancer," or, "We're all gonna die anyway." smh.

FatActor··on EPA proposes to strengthen air quality standards
All of your examples have one thing in common: a very long feedback loop.

Human brains weren't designed to comprehend feedback loops that aren't a few days (hunter/gatherer), weeks (exertion), or a few years at most (gestation, agriculture).

Feedback loops with half a lifetime or more are just impossible unless you practice thinking that way. American's can't even figure out interest rates or long term saving (it is an entirely different argument as to WHY our culture forces people to save for retirement, but I digress). I think most people are too busy or lack the capability to think in terms of long feedback loops.

Or it is the horror of knowing the consequences that cause some people to just shut down and go lalalalalafakenews

FatActor··on EPA proposes to strengthen air quality standards
> Cars are pure freedom

I think this is more a statement about your priorities than a generality about cars.

FatActor··on EPA proposes to strengthen air quality standards
I live in Portland. 70% of my friends don't have cars. My friends are in the 40-60 age range.

If you live in rural or poorly design burbs, cars are necessary by design. If you live in a city, like the vast majority of the world, you don't really need a car.

100x already assumes the answer, which isnt the case for the majority of the world.

FatActor··on Ask HN: Do you hate software engineering but love programming?
What you are describing is:

Hobby vs. career.

You basically want all the fun creative parts without the process and review and maintenance required for a product that has responsibilities.

It's like building a shed in your back yard vs. building a skyscraper in a city.

FatActor··on Heat exchanger header with fractal geometry
> True fractals are self-similar regardless of scale.

That's not true: the coastline of England is a well-known fractal and it has zero self-similarity. Self-similarity can be a property of some fractals, but it is not a requirement to be a fractal.

FatActor··on Heat exchanger header with fractal geometry
Is that really fractal in the sense of fractional dimension? Or is it just self-similar? I watched a video on this for 3b1b and it undid 30 years of thinking I knew what "fractal" meant and now I know nothing.
FatActor··on Makefiles for web work
Just making a bunch of phony rules is writing a shell script with extra steps.

How about converting electron-forge-webpack-ts to make. That would be epic.

FatActor··on Makefiles for web work
Not only that, but look at any advanced-age project that uses make. There are layers of includes, and defines and rules are smeared across multiple files.

I think many modern web-build tools were made by people who thought "hey, I can do better than make" (or worse, "What's make?" and reinvented the wheel) and then wound up in a similar conundrum.

FatActor··on whoarethey: Determine Who Can Log in to an SSH Server
Well, yeah, but I just got a chill realizing if I'm just dinking around trying to ssh into a random addresses that I'll be sending my public keys for auth which can be correlated.

Not a big deal, but I forgot about that leak, so "expose" made me read further and be reminded that clearly I am not a blackhat, or any color hat for that matter.

FatActor··on Pirate Weather: A free, open, and documented forecast API
If you asked me 25 years ago, "Wanna bet hackers will be excited about a weather API in the future?" ... Sink me ... I would have lost that bet.
FatActor··on The number of banks willing to do business with the crypto industry is shrinking
Back in the late 1990's I had a laptop and was working in a cafe and the barista asked me if I worked in tech - I said I did - and then proceeded to excitedly go on about how Transmeta was going to dominate the x86 market. Yes, a barista (not knocking baristas but they are not known for their deep vertical knowledge in subjects outside of coffee, except maybe english lit). This was the level of enthusiasm at the time for one of the first techno disrupters. It very much reminds me of crypto a few years ago spinning off a cloud of so many a non techie person with a deep-seated, poorly-informed opinion backed up by a Robin Hood account full of DOGE.
FatActor··on Learn Lisp the Hard Way
Do you speak multiple human languages? I speak English and French. There are subjective future tenses in French that can be transliterated, but don't really capture the spirit of the writer: one needs to elaborate in English with such verbosity that it takes a page in English to explain a sentence in French. I'm sure the reverse is true were I a native French speaker. My theory as to why so many existentialists were french was because the language was made for it. :)

Same goes for computer languages. I use LISP when I have computer science-y things I want to explore. For example, I was working on a path finding algorithm for fun years ago and I went to LISP because it is much more natural at conceptual programming. But I wouldn't use LISP to create a GUI, even though it can, nor would I try to write performant 3D graphics. But I would use it to craft a game engine (I wrote a frame language in the early 2000's as part of a game engine that I never finished because once i got the agents decision making working I felt satisfied enough).

The right tool for the right job...

Need to munge a file? PERL

Need to write an embedded application? C

Need to write a GUI? A JS framework (or Qt, or Motif/X if I'm feeling nostalgic)

Need to write a fast loop? ASM

Need to write a something stats-related? Python, R, JMP

Need to explore a computer science problem? LISP, SmallTalk (I don't know Haskell)

Need to work on a project that you're forced to? C++ :)

FatActor··on Please don’t film me in 2023
> Unless laws are passed to make filming others in public, this is unlikely to ever stop.

Assuming you mean the USA, the problem is you need people to enforce those laws or succeed with lawsuits (and dodge endless appeals or ascension to the SCOTUS). We can't even begin address gun violence in this country, I highly doubt we'll get consent-to-be-filmed-in-public-laws passed.

This walkthrough is a amazing and covers a lot of what you just said:

This is why programmers tend to faceplant when confronted with analog circuits, it is absolutely black magic that can't be brute-forced. :)

FatActor··on Playing Zork with AI-generated imagery [video]
> "We never got to see zork..."

Well... There have been so many visualizations of Zork over the decades. I still default to the InvisiClues images from the early 80's, which I think are far better than the first graphical attempts of the white house (Zork Zero).

However, this is extremely cool. It's like real-time Myst (yes, I know that exists, but that's a raytraced version of the original, not this). The meta data optimization was unexpected.

The video ended too soon.

FatActor··on Guitar Effects Guidebook, Vol. 20 [pdf]
OP here. Would be great to see some actual schematics of new ones. Can you point me to some? Here's the 80's pedal:

https://www.hobby-hour.com/electronics/s/boss-ce2-chorus-sch...

But can't find a modern Boss one. I guess they went to CE-5 after 1990:

http://thermionic-studios.com/wiki/images/2/26/Boss_CE-5Sche...

Guess I'll spend the next few days figuring out the diff.

My point is, you've provided just opinion. If you could have told me a thing or two about the actual circuits I might think you know what you're talking about. But rather than helping, you're just filling space with words in an attempt to sound knowledgeable.

FatActor··on Using Qt 6 under LGPLv3
Are we talking about the same thing? An OTA firmware update of 100MB seems about 100X what I'm used to in the Cortex-M space.
FatActor··on Using Qt 6 under LGPLv3
> (e.g. OTA update and the like).

What's linux FOTA like? It's dirt simple for most M-class devices, and most use MCUboot with two banks. I've not used it on Linux, but I can't imaging updating the kernal/distro OTA since it is so big, but I'm guessing just the application gets updated???

FatActor··on Guitar Effects Guidebook, Vol. 20 [pdf]
Would be great if we could get some actual screenshots of the boards rather than speculating. That's why I'm curious to see if 1985 is the same as 2023. Without data we're just guessing.
FatActor··on Guitar Effects Guidebook, Vol. 20 [pdf]
When I starting learning circuit analysis in college in the 80's I would draw out the pedal schematics via hand-inspection of the board itself and try to figure out wtf they were doing. I didn't have access to part #s until I was in college (you couldn't just google a datasheet for whatever 8-pin DIP was on the board, you had to look through giant catalogs of them from each manufacturer).

Two things immediately jumped out at me ... first, that undergrad circuit analysis does not help understanding circuits designed by wizened experts ... and second, that even the simplest circuits require all kinds of considerations beyond the y=H(x) transfer functions (and that linear systems don't begin to describe what i was seeing). Humbling.

It would be interesting to see how the Chorus schematic from 1985 compares to the Chorus schematic of 2023.

ANC gives me a whopping headache from the pressure, even since the early Bose days.
FatActor··on Ask HN: What sub $200 product improved your 2022
Winco fish spatula. Super flexy and thin. I can now make eggs the way I like them (over easy, zero browning) without destroying the egg or chasing it around the skillet like when I use bigger spatulae. Plus also much better for fish, oddly enough: the flexibility matters a lot.
