jmkr··on Suicide rates highest ever among middle-aged men
I keep wanting to say the same thing. In fact, how other people describe hobbies is why I don't like the term hobbies.

I think music is a good example of sometimes you need to not have fun to have fun. Practice isn't really fun, but if you can put up with it you can have a lot of fun. So you can say that the not fun parts are part of the fun parts because it's what gives you the payoff. But when people then go and send you a Suno generated song, and say it's better than yours, it is them devaluing the "not fun" parts you had to put up with. I've had people do similar things to code projects I've done. It's a real buzz kill.

I also really value when musicians critique my songs, even when I feel defensive about it. Because then it's not about them devaluing my time, it's about them helping me grow, and they know how it feels to go through that process.

jmkr··on Recreational Programming
This is how I feel, I like to share the cool thing I did and be part of creative spaces with other people, but I feel those spaces have gotten smaller, or changed.
jmkr··on As AI eats the web, the internet’s collective memory is disappearing
No, but I think a lot is, and it makes it (more) difficult to discover new music. There's still in person music, which is what it's about anyway.
jmkr··on As AI eats the web, the internet’s collective memory is disappearing
Indeed, I also don't listen to music after 2024. I'm also not interested in anything my friends have made (with claude or others). Or how so much of creativity is now a prompt away.

A lot of our culture is disappearing before our eyes and people are defending it.

jmkr··on Wayland set the Linux Desktop back by 10 years?
Pretty much every vst, clap, etc plugin on Linux requires X calls because of how windows get created and then managed by the host.

I've moved to running Bitwig in an Ubuntu distrobox container. Hope you're enjoying 6, it seems they fixed a lot with the piano roll.

I had to set mouse warping off in my tiling manager for yabridge/wine plugins.

jmkr··on Beyond has dropped “meat” from its name and expanded its high-protein drink line
Costco and similar do have them at a decent price, currently see them 20$ for 10. I think most people just look at the 2 packs, which are more expensive.
jmkr··on Why can't you tune your guitar? (2019)
I play with generally lighter strings. 8.5-40 mighty slinky fender scale. I noticed when I switched my fingers pay much more attention to pressure, and being in tune with microbends.

Been thinking of going a bit lighter recently, and also getting a classical.

jmkr··on Ask HN: What Are You Working On? (Nov 2025)
I have been building music theory/midi related vst plugins in JUCE.

It's mostly targeted at me, or others that make music, but are not piano players.

There isn't much to show currently, but I have a rhythm generator, and have been working on a chord builder. The main thing that has taken time has been trying to decide which things to add to a user interface to make it worth actually building.

jmkr··on We'll need a universal basic income (UBI) in an AI-driven world
Isn't it that you sign up for Star Fleet, go through school, take tests, and then get assigned to a position?

Not everybody is in Star Fleet, so I assume people want the ability to travel the stars and they'd be happy enough scrubbing torpedo tubes.

jmkr··on Slow
I think in the western world, Art, and music are both long term projects. So much so that we seem to have "reinvented" music at least twice. Once after the Greeks into classical western music, then again when jazz went into tonal harmony.

At least parts of it are "scientific" and "directed," see the Lydian Chromatic concept for example https://en.wikipedia.org/wiki/Lydian_Chromatic_Concept_of_To...

jmkr··on Show HN: Convert from MIDI file to ASCII tablature (and more)
Awesome OP. I'll give it a shot because I've been considering doing something similar for chord charts. Glad to see abc notation support.
jmkr··on Beyond Meat fights for survival
This is a really important point that I think a lot of people who aren't vegan don't get. There might be an understanding that food is culture (lets order chinese, or italian), but realizing that's not a culture you experience but a culture you live.

The first thing many new vegans ask is "what do I eat now?" The replacement food comes first, and beyond hits the mark a lot more than seitan does because we don't culturally eat seitan.

And even more so, I think beyond has made it so an entire generation realized they could go vegan. A black bean burger just never hit the same way.

jmkr··on A Lisp adventure on the calm waters of the dead C (2021)
I think Lisp is more on the liberal arts side of programming languages.

That the "enlightenment" of Lisp is that you can use functions everywhere. Write macros that look like functions and modify behavior, and build your code as a language.

Things like monads are more on the evolution of functional languages, and I also fall off the bike. It's as difficult as you want it to be, and I find scheme and lisp to be easier high level languages than javascript or python and makes more sense.

The forward and preface to SICP is good reading.

https://mitp-content-server.mit.edu/books/content/sectbyfn/b...

The Dan Friedman books are pretty good in general: "The Little Schemer," and the sequel "The Seasoned Schemer" which are both more "recursion" books. He also has another book "Scheme and the Art of Programming." Which I think is a great comp sci book that's not too difficult and doesn't seem too well known.

How to Design Programs is supposed to be a pretty good comp sci intro:

jmkr··on Long live Xorg, I mean Xlibre
A few weeks ago I was looking into `XReparentWindow` because certain things use it (DAW Plugins). I don't think Wayland can do something similar (but I guess XWayland works), GTK and Qt both seem to have their own version.

Looking more into plugin libraries, a lot of it is based specifically on X, I don't think that's going to be rewritten anytime soon.

I've felt for a while stuck between X and Wayland. Same with Pipewire and Jack/Pulse.

jmkr··on Just Fucking Code
Shut up n play yer guitar.

You can practice playing over the changes, or you can go to the bar, watch netflix, or do anything else.

But in 10 years are you going to be able to play over the changes?

If you remove llms from the article everything is still the same.

jmkr··on Compressed music might be harmful to the ears
My Bitwig template: limiter on master track. My Renoise template: limiter on master track.

Now I have no fear of loading random presets.

jmkr··on Ask HN: What are you working on? (April 2025)
One of my goals for this years was to get a jazz teacher, specifically for guitar.

A layoff killed that goal for the foreseeable future.

Theory has helped me practice like I think you're supposed to. More structured, more analysis. It also tickles the same part of the brain the certain comp sci topics do.

I think it came from wanting to learn how to improv, and then wanting to make my own songs. So I make a few tracks a week, of different genres, depending on what I'm interested in at the time. I've seen improvement, and I take notes about what I learned/what works.

jmkr··on Ask HN: What are you working on? (April 2025)
A midi sequencer, which does or is supposed to do what you expect.

In the process of adding stuff like euclydian sequences, and trying to figure out how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory behind it.

It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.

jmkr··on Benn Jordan's AI poison pill and the weird world of adversarial noise
Yes this is pretty much it and it's obvious to me.

There's a big corollary to FOSS and gpl, but a lot of people seem to miss it. This future isn't for our culture, it's for business. And since our culture requires making money to make things adjacent to art, less culture will be made.

A lot of generated music is good enough to wind up in playlists. Lots of live bands already fake it, and lots of music venues have already replaced live music. That doesn't mean music will die, it just means it's harder to discover new music and go see a show.

I think there's some European countries that have some kind of basic income/stipend for artists. If this is the direction of the future we need to ensure something like this exists.

jmkr··on What's in that bright red fire retardant? No one will say, so we had it tested
I really hate that companies are allowed to use "natural flavors" and I refuse to buy any products that say that unless they are able to specifically tell me what's not in it.

Lots of people don't realize that "natural" can mean pretty much anything that's not produced in a lab.

There is a trend though where some companies include in the nutrition facts the sources of their ingredients. That's how it should be.

In the US you can write "modified food starch" and that can mean a million different things. In Europe they have specific numbers for different types of "modified food starch."

jmkr··on Erica Synths DIY Eurorack Modules
> Musicians love a good trend to dump money into.

If I get just one more thing my music will sound good :)

Euroracks will not go out of style in any serious way, in the same way guitar has not gone out of style over the years even though there were fads.

A few months ago I bought a https://www.dreadbox-fx.com/erebus-reissue/ (semi) and within an hour I decided modular was cool.

Funny enough I was just looking at the Erica Synths github the other day. There's been a few synth and audio posts on HN the past few months. Pretty cool to see it.

jmkr··on A deliberate practice app for guitar players who want to level up
> This is why learning guitar when I was younger was so difficult to me

I agree. The downvoted op is right in a way. Guitarists have a way to make things difficult. Just learn to play the 1 octave major scale/arpeggio, and triads, then 7th shells. The guitar is relative, a 1 octave scale on a guitar is the same, on keyboard it's positional.

However it's worth mentioning that I think Berklee does teach patterns, and a few jazz guitarists say to learn it too. It almost seems like learning guitar is not as worked out as other instruments. Everybody that gets good winds up having to learn all the things other guitarists have had to figure out over years after they rote learned it.

jmkr··on Numbering should start at zero (1982)
A symbol being arbitrary doesn't influence the reality of the meaning behind a thing. I've always thought about `zero` while counting, it never was about `0`.

I observe zero.

I don't think zero is an absence of quantity. I don't think zero is the null set.

You can write types in a programming language, but there are other type theory books that do include zero in the natural numbers. And type theory comes from number/set theory. So it's ok if you decide to exclude it, but this is just as arbitrary.

In fact I'd be happy to write `>=0` or `>0` or `=0` any day instead of mangling the idea of zero representing 0 and zero representing something like `None`, `null` or any other tag of that sort. I don't think the natural world has anything like "nothing" it just has logical fallacies.

jmkr··on Numbering should start at zero (1982)
+1 for peano arithmetic club.

I never realized it was controversial. I think I've always included 0 in the nat numbers since learning to count.

But there are some programming books I've read, I want to say the Little Typer, or similar, that say "natural number" or "zero". Which makes actually confuses me.

jmkr··on Unsafe Rust is harder than C
Thanks. Yeah that makes sense for low hanging fruit. Going through the gcc flags it does seem like a lot of tradeoffs have to be made so you can't cover everything. A quick look through compiling Rust it seems it does at least some of this checking at MIR. I'll have to read more about it.
jmkr··on Unsafe Rust is harder than C
Thanks that's helpful I'll take a look at model checking.
jmkr··on Unsafe Rust is harder than C
Can you explain what that low hanging fruit is (or refer me to docs), and also explain it being a decision problem a bit more thoroughly. I will accept that if you have to run a program to decide if it's memory safe then that fits the criteria, but from my understanding static analysis doesn't run the program, and a compiler is parsing and lexing anyway so it should be able to catch at least some things (the low hanging fruit)?

Since I have actually started using C I realized how easy it is to be lazy and not handle memory right so it makes Rust and maybe C++ seem more appealing, but trying to figure out random segfaults it seems like address sanitizer and valgrind catches more than I would have assumed is a low hanging fruit.

I guess I should look more into how Rust manages that safety or understand what memory safety is trying to accomplish more formally. I've taken GC for granted for years until I needed to care about memory.

jmkr··on Holding a Program in One's Head (2007)
I think this is addressed in the link under that section

https://paulgraham.com/power.html

> I think that the main reason we take the trouble to develop high-level languages is to get leverage, so that we can say (and more importantly, think) in 10 lines of a high-level language what would require 1000 lines of machine language.

...

> 5. Write rereadable code. All programmers know it's good to write readable code. [...] If you're writing for other people, you may not want to make code too dense. Some parts of a program may be easiest to read if you spread things out [...] Whereas if you're writing code to make it easy to reload into your head, it may be best to go for brevity.

jmkr··on Holding a Program in One's Head (2007)
This is probably a common; lisp/scheme type of thought. Dan Friedman also said something about how he only likes code that he can hold in his head to think about in the shower. I forgot the source, but it's in one of the talks. I think Sussman has also said something similar.
jmkr··on Holding a Program in One's Head (2007)
There's some idiom that says something like "you don't understand something if you can't explain it." I think this is the real point of code review. To make a case for why your code is valuable. If it's just a blob of 1000 lines of "refactor" or "adding feature." It means nothing. A good commit has some kind of abstract tailored to what work was done.

Then a review becomes something like "the claim was made this function does this, does it look like the function does what it says it does?" If you can understand it in context, then you've added trust and knowledge of how it works.

However it seems to often be the case a review turns into "I like this word better than that word" so back to the explaining it point, it becomes a bit of a self review with the hope it might be helpful to somebody else in the future.
