mrkgnao··on 2017 is not just another prime number
Use the absolute value, maybe? You might have duplicates, but both n and -n can be special :)
mrkgnao··on Atom-in-orbit: Putting Atom in the browser
Wow, this is good. I'm guessing highlighting support could be improved -- I opened a Haskell file and it was just plain text.

One remarkable benefit for me is the fact that this plays nice with Vimperator.

mrkgnao··on Ask HN: What do you want to learn in 2017?
Math-wise, well, it's a matter of where I go to college, I figure it'll have a huge effect on basically everything that happens thereafter. I definitely want to continue on my path towards understanding the Weil conjectures and that kind of thing, so I plan to be able to compute sheaf cohomology for schemes by the end of the year and learn more algebraic number theory. (And maybe look at representation theory.)

CS-wise: learn enough ClojureScript to be able to make convincing mathematical (etc.) visualizations -- I recently got a taste of Figwheel+Reagent and I'm hooked! -- and be able to manipulate Haskell transformer stacks better.

Other than that, I'd like to learn some French (marathoning Engrenages was the best decision ever!) and not forget the little German I know.

It's fine :) How long is this supposed to take?

ray-test requires an argument.

No! I myself am a math enthusiast, as you can see :)

I'd love comments!
mrkgnao··on Show HN: Refinator, online lecture notes and PDFs with prerequisite lists
I haven't worked on this in a few months, so I figured I'd just show off the current state of the project since I'm unlikely to be able to work on it in the next couple of months (since I'm in my last few months of high school, and I'll have a lot of exams and such things to deal with). I posted this yesterday[-1], but it didn't get much attention so I figured I'd try one more time.

This is a really simple proof-of-concept for something I've often wished to be able to use myself. Among other things, I've often felt that prerequisite and "read alongside" lists (ideally based on (topic, sophistication) pairs instead of being specific books as it currently is) would be great to have when you're reading something technical. The about page[0] goes into more detail on this.

Please consider adding any documents you frequently refer to to the list: I've seen searches for, among other things, neural networks, modular forms, type theory, von Neumann algebras, and probability in my logs!

Contributions to the code[1] are welcome too! :)

I haven't worked on this in a few months, so I figured I'd just show off the current state of the project since I'm unlikely to be able to work on it in the next couple of months.

This is a _really_ simplistic proof-of-concept for something I've often wished to be able to use myself, although I should really support real books as well. Among other things, I've often felt that prerequisite and "read alongside" lists (ideally based on (topic, sophistication) pairs instead of being specific books as it currently is) would be great to have. The about page[0] goes into more detail on this.

Currently, I plan to integrate with MathOverflow/MSE's tag wikis, and maybe allow rep to transfer over in some sense from there by allowing you to link your accounts.

Any edits or additions would warm my heart. Contributions to the code[1] are welcome too! :)

I'm running Arch on a Chromebook (an Acer one).

That sounds like "Alexander". Interesting.
mrkgnao··on Why I still won’t review for or publish with Elsevier
Each journal focuses on a specific subfield of math/CS/$SUBJECT, so they can make more informed evaluations on the quality of the research than an expert in some other field can.
mrkgnao··on Dichronauts
I've just come here to say that I came here after literally finishing _Permutation City_ around two hours back. It was great.

I can't wait to try Schild's Ladder -- differential geometry, yay!

I wonder if there are any people who market homeopathy targeted at vocal training. How would that even work (I mean, in terms of similia similibus curentur or whatever)?

You should look into LatexMk[0].

I think Westworld naming the next episode "The Well-Tempered Clavier" could, somehow, lead to a resurgence in interest in GEB -- lots of people on /r/westworld seem to be interested, for sure! (For one, I've heard that the show's creators have admitted that they are creatively indebted to the book in some ways.)

I'm mostly interested in the kind of work a lot of Haskell/OCaml users do as "quants".

mrkgnao··on Don't Give Up on the Guitar, Fender Is Begging You
For me, nails are an on-and-off thing. My right hand has never hurt either way (and I haven't been playing for a long time).

> And people quit electric guitars more often than acoustic ones, he said, because of the pain factor: Steel strings hurt delicate hands.

Huh? I can only imagine that they meant s/acoustic/classical/, because both acoustics and electrics have steel strings (and, of course, steel strings on an acoustic have significantly higher tension than those on an electric). Classicals have nylon strings.

mrkgnao··on Gosubc – An implementation of the SubC language in Go
That's very similar to what I do now. I was looking for something more systematic than "hope you stumble across cool words" :)

I did not know that energy and lethargy come from the same Greek root, though, thanks!

mrkgnao··on Who Will Command the Robot Armies?
I wonder if the images are all that's on his slides when he gives a talk. It would certainly require a great deal of facility with public speaking to be able to pull that off. Kudos to 'idlewords if that is indeed the case.
