marchdown··on Ask HN: What weird or hard problems are you trying to solve?
Unethical Thought Experiments: what if Twitter shrank the retweet button or hid it under the fold to but the brakes on the viral spread?

Put amplification behind a trivial inconvenience that would make knee-jerk retweets less frequent and allow the whole chain reaction to cool down.

marchdown··on Millitext – A subpixel text encoding font
Since no one has presented a version of the dotsies bookmarklet, which is actually necessary to use them in practice, I'll go and make one with the proper mapping for v3.

If there is one already, let me know.

Actually, looks like all the permutations in the bookmarklet only allow you to use glyphs in Dotsies.tff, and there are some possible glyphs missing. I'll have to edit the font file.

marchdown··on Surviving Jonestown
This sounds interesting. Do you remember the essay or more details so that I could google it?
marchdown··on So You Want to Open a Small Press Bookstore/Artist-Run Space? A Cautionary Tale
I'd be interested in seeing your list.
marchdown··on The terrible 'what if': how OCD makes every day a matter of life or death
I might offer some insight here. I’m slightly obsessive about not inconveniencing other people. I try hard to put things in their proper places, not to eat the last bite of anything without asking or being offered, not making noise, not leaving electronics in misconfigured states, not leaving my own stuff lying around, I could go on.

It’s worse than the few obsession I’ve had around my own preferences, because I lack the introspection when it comes to people other than myself. I don’t know if they are sensitive to this or that particular nuisance and my priors seem to be dialed up to eleven.

I end up trying not to be around other people do that I won’t fall into these obsessive patterns as often.

marchdown··on I'm Scott Aaronson, quantum computing/computational complexity researcher. AMA
What are some research areas complementary to the quantum computing/computational complexity where additional effort would remove roadblocks in QC research?
marchdown··on Vladimir Voevodsky has died
Oh no! I was following his work closely and had high hopes for him delivering on his vision: type theory and constructive notion of equality not getting in the way of doing mathematics with computer, but helping us along. It will hopefully will be picked up by his collaborators.
marchdown··on iPhone X
This does ring true, but I can't think of any reliable sources backing that up. I'd appreciate it if you mentioned some.
marchdown··on Ask HN: I feel like helping somebody out, what can I help you with?
Thank you!

I've just send a note of appreciation to the Centre for Effective Altruism. Let's hope that's a first step. I'll try keeping track of them @ https://mastodon.xyz/web/accounts/75086

Use the positive feeling to propel myself forward, you say? I'll go help my housemates with the chores and do a writeup on formal correctness proofs.

Sure beats feeling bad about not applying for jobs here more aggressively.

I'll keep in mind your suggestion of starting tiny, starting over instead of staying stuck, and not overemphasizing the big picture. I'm grateful you took the time to answer.

marchdown··on Ask HN: I feel like helping somebody out, what can I help you with?
I could use some encouragement and life advice. I apologize if this ends up being long and whiny.

I feel like I'm stuck on the outside of the part of society where all the meaningful intellectual work happens.

Since I was a child I have always aspired to learn from the scientists and engineers and humanitarians so that I could be like them one day. I've read Hamming, Feynman, Norvig, Herbert Alexander Simon, and felt that those were the people who have gotten it right, that that's what life should be about. Explore the world, do hard, honest work of figuring things out and building something new that helps people realize their potential and live better. Find the math behind the mundane and harness it to improve the human condition.

But I've been struggling with depression for years and I'm ashamed of how I spent my time in university. I feel that I haven't found a mentor or path of my own. I've constantly felt overwhelmed and let down by myself and by the system. I feel that I don't have the skills or the resolve to just plow ahead and do things. I feel that whenever I try to do research, or write, or even think out loud it ends up with a mockery of the real thing.

Right now I've graduated from a five-year course in computational linguistics, did half a year of antidepressants, half a year of advanced math seminars and moved to Israel for a change of scenery. I would really like to find a collective here where I could learn and solve real problems. Join a startup or do a PhD.

I still have a crippling case of impostor syndrome and occasional panic attacks. If any of you here have suggestions — however specific or general, — I would really appreciate it.

marchdown··on IHaskell – A Haskell kernel for Jupyter
I want to get involved with an open source project, I am familiar with Haskell and enthusiastic about making it more accessible. I've just completed an educational project where I've used iPython with my students and I would have used Haskell if the tooling were a bit smoother.

So far the entry barrier was too high for me but I want to reach out and ask if anyone is willing to hold my hand a little so that I might get over the initial hurdles. Could you suggest some entry points for me? A bug tracker, an IRC channel, a github issues page? Should I just hack on it on my own until I have a specific unit of work to contribute, or is there someone who could use my help with the coding and provide guidance as to the organizational side of things?

marchdown··on David Bowie Has Died
> The vast majority of people wish to belong to the tribe of “The vast majority of people.”

This is not obvious to me at all. Would someone please explain?

marchdown··on Today's world is amd64, armv7, and soon aarch64. Everything else is dead
ARM has notoriously low energy dissipation due to low voltage.
marchdown··on The category design pattern
What are some examples of good pedagogy in programming?

I would point to pretty much anything by Norvig, Knuth, Sedgewick, and maybe to Zed Shaw's agressive tutorials.

marchdown··on The Ashley Madison Database Was Leaked
Consistency is shooting yourself in an even number of feet. How is it ethical to dox people that are being made into villains?
marchdown··on What’s the best way to spend $20K to help the common good?
Thank you for that. That's the stance that I naturally gravitate to, but one I have been doubting lately. Your comment is encouraging.

This might not be the most effective way to steer your resources towards common good, but there's this persnickety failure scenario where a man in need may receive material support but still lack a human connection and a sense of belonging.

Of course, you're still literally trading off human lives for a warm fuzzy feeling of personal involvement.

I'm looking forward to Peter Singer's upcoming Coursera lectures on effective altruism, I want to see him develop this position with rigor. Meanwhile http://www.givewell.org/ has a good analysis.

marchdown··on Show HN: Explore 16 Years of Green Card Applications
What is notable here is the low approval rate.
marchdown··on Show HN: PreTeX, a LaTeX preprocessor to make math typesetting easier
It is meant for those who are already familiar with LaTeX but do not have a handy unicode input method. Emacs has a feature that allows you to literally type \alpha or \in or any of hundreds of other LaTeX commands and have it substituted with the appropriate unicode character right in the plain text buffer you're editing.
marchdown··on Amazon Echo
Now, replace "Alexa" with "Hey Siri" and you don't need another device.
marchdown··on Readmill shuts down, team joins Dropbox
Take a look at http://marvinapp.com. It has some fancy typographic and organizing features. I found it not to my taste, but YMMV.
marchdown··on A Geometric Review of Linear Algebra [pdf]
I would love to see your take on this dependency graph, no matter how subjective and incomplete it turns out to be.
marchdown··on People with nothing to hide
What you missed is that "nuhhuh, you do, too, here are some things you didn't think about" is not always the adequate response to "I have nothing to hide, or at least I can't think of anything". There's also the matter of public policy, accountability of government, misuse of neutral data by your adversaries, discrimination, and a whole lot more.
marchdown··on People with nothing to hide
That's far from the only reason to encourage privacy.

I don't really know how to respond to here. I believe that I see your point, but even though I wouldn't mind my answers to that questionnaire being made public, I still feel that both communal and personal interests of members of society would benefit from institutional pressure in support of privacy, and strong crypto for that matter.

marchdown··on Confirmed: The NSA is Spying on Millions of Americans
You can do that, I tried.
marchdown··on As Math Grows More Complex, Will Computers Reign?
Thanks.
marchdown··on As Math Grows More Complex, Will Computers Reign?
I'm not sure that it's appropriate to ask, but I would love to see the paper.
marchdown··on Google Announces $1,299 Chromebook Pixel With 2560×1700px Touchscreen
the cloud part was the point; the old hardware was supposed to be cheap enough for casual use, or for casual replacement for that matter.
marchdown··on Slate: a Mac OS X window manager for power users
Emacs 24.2.1 here, no matches for "ns-toggle fullscreen".

Edit: no luck with the latest pretest (24.2.93.1) either.

marchdown··on Slate: a Mac OS X window manager for power users
How do you get true fullscreen mode in Emacs on OS X?
marchdown··on Introducing Boxen
There's nothing keeping you from using the same X11 apps on OS X as you do on Linux.
