ramenbytes··on My mental model of setf was wrong
Do you have this list typed up somewhere?
ramenbytes··on My mental model of setf was wrong
> Now maybe my mental model of self is wrong and I need to learn LISP and create a mental model for setf and that will lead me to an awakening of a correct mental model of self?

ramenbytes··on The Input Tube [pdf]
> Part one of the less popular and much more brief third edition of the Radiotron Designers Handbook [0] is probably my favorite writeup but is very dense and covers a good deal of stuff in those ~80 pages.

I'll have to check out the RDH section. So far I've been working through "Theory and Application of Electron Tubes" by Reich, which as a physics person I've quite enjoyed. I'm guessing the RDH section is a compact summary of the stuff in Reich's book.

> Aiken Amps White Papers [1] is pretty good and the first amplifier I designed (and built) was completely done through those pages, still have that amp and have sold it twice and bought it back twice.

I'd already stumbled across his stuff before, but didn't realize there was a nice organized listing of everything, so thanks for that. Looks like he has a useful bibliography too, from which I just found several interesting reads: https://aikenamps.com/index.php/a-bibliography-of-must-have-...

Aside, another bibliography I've found useful (complete with PDFs): http://www.tubebooks.org/

About a year ago I submitted the book this is from, and a user, @fuzzfactor, offered to provide more relevant info on the linked section if desired (https://news.ycombinator.com/item?id=34299135). I saw that comment after the reply window closed, so I'm submitting just that section to hopefully catch their attention and generate some discussion on it.

Thanks!

Can you recommend any good books or resources for learning polyphonic compositional methods and/or about the other known methods?
ramenbytes··on Safe Operating Area Issues Thermal issues in MOSFETs operating in linear mode
I've been sorting out what mosfets are suitable for linear use since I've heard rumors that modern ones are less capable in that regard, and I found this article to be a good resource on the issue.
ramenbytes··on Learn in Public (2018)
Reminds me of a favorite quote from Fahrenheit 451:

> Man, when I was younger I shoved my ignorance in people’s faces. They beat me with sticks. By the time I was forty my blunt instrument had been honed to a fine cutting point for me. If you hide your ignorance, no one will hit you and you’ll never learn.

ramenbytes··on The unexpected poetry of PhD acknowledgements
Woah. That helps visualize it, thanks.

For those like myself wondering how a regular wave could do this, the article says it was something colloquially termed a "sneaker wave." Like a rogue wave, but on the shoreline. It also sounds like they all got hit by the wave, and only Charity survived.

Edit: National Weather article on Sneaker Waves: https://www.weather.gov/safety/sneaker-waves

Apparently the cold water and other complications make things worse.

ramenbytes··on We need visual programming. No, not like that
The sort of visual programming the author talks about seems like it could benefit from the concepts of presentations and semantic graphical output as seen in projects like CLIM (the Common Lisp Interface Manager).
ramenbytes··on $1B gift to make Johns Hopkins medical school free for most
> I don't like the financial aid system in general, it's really bad for young adults with rough backgrounds. Not everyone has a good relationship with their parents.

Having gone through the community college and state university system, it wasn't that uncommon to hear students say "my parents make too much for me to get aid, but they don't contribute to my schooling" when discussing financial stuff.

ramenbytes··on Ask HN: Is there any software you only made for your own use but nobody else?
At least with GPS, I've found a reasonable substitute to be an honest-to-god map. Here in LA the Thomas Guide is fantastic, but other places have "road atlases" that function similarly to my knowledge. In some ways I find it better than Google maps, because it's actually designed to be a map instead of a robot overlord dictating what you do.
ramenbytes··on Overleaf: An open-source online real-time collaborative LaTeX editor
Usually right before deadlines.
ramenbytes··on Overleaf: An open-source online real-time collaborative LaTeX editor
> The big hurdle now becomes that all collaborators now need to know emacs;-)

As God intended. ;) They actually don't though, if they prefer to remain heathens see bottom of this reply.

> Although I am curious as to how clicking on TeX leading to scrolling the PDF to the corresponding location in the PDF would work (and vice-versa).

Could be wrong, but I think the synchtex files produced by builds are for that. I usually have the PDF open in one Emacs buffer (you can view pdfs in Emacs), and the TeX file open in another. Ctrl-left click in the PDF jumps to the spot in the text buffer for that spot in the PDF, and in the TeX buffer there is a keybinding to do the reverse. Probably a way to click and get there too, but I use the keybinding.

> I'm assuming you need to host an emacs server

No, Emacs runs locally and interfaces with the cloned git repo on your machine. Your collaborators could use Notepad for all Emacs cares, as long as they work in the same repo and push to the shared remote.

ramenbytes··on Overleaf: An open-source online real-time collaborative LaTeX editor
> Maybe other tools do some of these things, but having all of them in place is nice.

Emacs. I have almost everything you mentioned out of the box with doom Emacs, and the other stuff should be trivial if it doesn't already exist.

Like a sibling comment mentioned, it sucks for synchronous work with colleagues. Async is fine though.
ramenbytes··on Overleaf: An open-source online real-time collaborative LaTeX editor
Yup. When I was using it, I don't think it was literally every keystroke but it was something pretty granular so that if your contributors were working on the document it was a nightmare to get anything pushed since it kept changing under your feet and causing conflicts. Finish a merge, and another one is waiting.
ramenbytes··on CriticGPT: Finding GPT-4's mistakes with GPT-4
Politics and related stuff is what I had in mind, yeah. To a lesser extent technical topics as well. But, I meant "good faith" in the sense of both believing what they're saying and also approaching the argument open to the possibility of being wrong themselves and/or treating you as capable of understanding their point. I've had arguments where the other person definitely believed what they were saying, but didn't think I was capable of understanding their point or being right myself and approached the discussion thusly.
ramenbytes··on CriticGPT: Finding GPT-4's mistakes with GPT-4
> I completely agree with that, but the problem is finding a supply of people to argue with on niche subjects.

Beyond just subject-wise, finding people who argue in good faith seems to be an issue too. There are people I'm friends with almost specifically because we're able to consistently have good-faith arguments about our strongly opposing views. It doesn't seem to be a common skill, but perhaps that has something to do with my sample set or my own behaviors in arguments.

ramenbytes··on CriticGPT: Finding GPT-4's mistakes with GPT-4
> I'll ask it a question about temporal logic or something, it'll say something that sounds accurate but is ultimately wrong or misleading after looking through traditional documentation, and I can fight with it, and see if it refines it to something correct, which I can then check again, etc. I keep doing this for a bunch of iterations and I end up with a pretty good understanding of the topic.

Interesting, that's the basic process I follow myself when learning without ChatGPT. Comparing my mental representation of the thing I'm learning to existing literature/results, finding the disconnects between the two, reworking my understanding, wash rinse repeat.

ramenbytes··on A new RISC-V Mainboard from DeepComputing
Will schematics be available to repair shops for this mainboard too? I wonder if it being developed by a partner changes anything.
ramenbytes··on Workshop on the Psychological Reality of Lisp (1981)
The comment below reminded me of this article, but I haven't been able to find it (the article) again until now.

Solid, actionable advice. Thank you, and good luck!
ramenbytes··on Why "Structure and Interpretation of Computer Programs" matters (2011)

After you finish that, I recommend queuing up Friedrich Nietzsche by Klaus Schulze.

ramenbytes··on Experts vs. Imitators
Soon-to-be grad student here. Could you expand a bit? Is there anything you recommend doing ahead of time to weed out some of these tarpits, or is the already mentioned heuristic the best we've got so far?

Check.

As an Android user, I'd counter "Signal". Which I think would bring things back to what another comment mentioned about preferences in messaging platforms.
