unzadunza··on Yes, it's OK to be mad about crime in San Francisco
I think people get scared and then panic. Not many folks are used to being around a person who is bleeding from a stab wound.

I was walking home through a park and saw a girl who was slumped over and it looked like she was dead. My heart started pounding, for some reason it scared me pretty badly. I went and found the police and they refused to even believe me. I then found another homeless person and asked her to check (part of the reason I didn't want to go near is that I'm a male).

Anyhow, I was scared.

unzadunza··on Moody's downgrades US banking: ‘rapidly deteriorating operating environment’
I just realized it’s really easy to upvote a comment accidentally while scrolling on my phone with my left thumb (I’m a lefty). But what the heck, I like that joke.
unzadunza··on Ask HN: Something you’ve done your whole life that you realized is wrong?
And my favorite one from my wife:

A modern day warrior Mean, mean stride Today's Tom Sawyer Mean, mean guy

unzadunza··on Ask HN: Something you’ve done your whole life that you realized is wrong?
Ha! This is another one of mine, but I had thought, for a while, that it was 'hey there Rodrigo'
unzadunza··on Ask HN: Something you’ve done your whole life that you realized is wrong?
For 30 years I sang "whoa-a, head waving" instead of "whoa-a, we're halfway there"
unzadunza··on Gattaca draft script (1997)
I guess you couldn't call it underrated (93% rotten tomatoes) but Vast of Night was my favorite sci-fi movie I saw this year.
unzadunza··on Ask HN: Are there any books that changed your life during college or school?
This is really high up on my list too. I came in with the same preconception about him that you describe. It was inspiring to see how he changed throughout the book.
unzadunza··on Ask HN: Are there any books that changed your life during college or school?
On the Road. Reading that gave me the kick I needed to get out of my home town, live in other places, join Peace Corps, and question my status quo.
unzadunza··on Talking to strangers can make us smarter?
I'm really reluctant to talk to strangers, but when I do... I use triangulation, where you don't talk about yourself (a stranger doesn't care) and you don't talk about them (it makes them uncomfortable), but instead you talk about a 3rd subject that maybe is visible to both of you, like the pretty fall leaves.

Actually, last year, right after I learned about triangulation, I was walking my dogs and stranger mentioned the pretty fall leaves to me. I then started telling him that he was using triangulation and explained what it is. He got uncomfortable and walked away. Derp.

unzadunza··on Why adults still dream about school
For me: time for finals and, oops, I didn’t attend a single class and I have no idea what the final will be about.

Maybe this dream is due to the fact that I missed at least half of all my classes because of basketball at the rec center.

unzadunza··on Using Nix on macOS
I just tried that and it resulted in a black screen. I suppose there is more to using that video driver than just that line in a nix configuration?
unzadunza··on Using Nix on macOS
Thanks for pointing out mitchellh/nixos-config. Do you have a config published for nixos with UTM? I’m having a heck of a time getting the screen resolution and font sizes where I want them and I’m kind of lost.
unzadunza··on Deepest infrared image of universe
I like this.

My 'bad' mental model is: In the beginning there was an infinite amount of space and somewhere within that space the Big Bang happened. The universe is all the matter and energy produced by the Big Bang and that universe is expanding at a maximum speed of C through the infinite amount of space.

But you are saying, I think, that before the Big Bang there was no space. The Big Bang produced all the matter, energy, and space itself. And space is expanding, NOT just the matter and energy expanding through the infinite pre-existing space that I imagined.

I still have a very hard time imagining 'no space' before the Big Bang and the concept of space being something besides 'nothing'. Because if space is expanding it must be something more than nothing.

unzadunza··on Deepest infrared image of universe
Let's say the universe is 14 billion years old and the galaxies in this image are 13 billion years old. The largest the universe could have been at the time is 2 billion light-years across if the universe expanded at the speed of light after the Big Bang. However, if we pointed the Webb in the exact opposite direction we would see galaxies that are 26 billion light years away from those in this image. How is this possible if the galaxy could have only been 2 billion light years across 13 billion years ago?

Also, if the Milky Way galaxy was somewhere within the 2 billion light year diameter sphere of the universe at that time (it wasn't because it isn't that old), the light from this image should have hit us a long time ago.

unzadunza··on Ask HN: What'd you do while HN was down?
I recorded a song on my guitar. It is so bad it makes me sick to my stomach.
unzadunza··on Why software engineers like woodworking
What kind of mill did you get? I've been interested in one but I don't have that much space and I've heard that benchtop mills are not that useful, I hope that's not true since it would be my only option.
unzadunza··on Ask HN: Where do you find your sense of purpose working in the private sector?
I worked at a national lab for 5 years and loved it, but I know exactly how you feel about the negative parts. I left and ended up at an ad-tech company and although I didn't like our mission at all, enjoyed the job just because of all the new skills I learned. Eventually I had to leave because I just never could feel good about what we were building.

Then I ended up at my current company. Our mission is to improve supply chains by monitoring vaccines (mostly in Africa at the moment) and perishable goods with our sensor devices. Especially with the vaccines, our mission is literally to save lives. I LOVE it here.

So, the private companies you are looking for are out there, so maybe just stay patient until you find something that you can feel good about.

unzadunza··on NASA says Webb’s excess fuel likely to extend its lifetime expectations
Nope, Han Solo is the first space bro.
unzadunza··on $2,295 5-port Ethernet Switch for Audiophiles
Even that site, though, feeds into audiophile irrationality. The DAC reviews, for example, throw a bunch of measurements at you, but there is no way a human could hear the difference in the best and worst DAC.
unzadunza··on Nextspace: a desktop environment that brings a NeXTSTEP look and feel to Linux
Does anyone know if Nextspace apps have emacs keybidings just like NeXTSTEP (and MacOS)? If so, this is the Linux desktop I've been craving.
unzadunza··on Ask HN: Have you picked up any new skill from scratch in your 40s or later?
At 48 I bought a TIG welder. It was difficult at first, but now I can weld steel, aluminum, and stainless and it usually doesn't look like crap. It's very fun.

Then last year at 49 switched from right handed to left handed guitar since I'm left handed and was never very good right handed. I've been practicing every day for at least an hour for 11 months now and enjoy it a lot.

unzadunza··on Second cable breaks at Puerto Rico’s Arecibo telescope
This observatory taught me a life lesson: after finally beating Trevelyan after 100s of attempts I learned I'll never be very good at video games.
unzadunza··on Volunteers spot almost 100 cold brown dwarfs near our sun
I had to look it up, because I'm curious too. It looks like volunteers are given images from NASA's Wide-field Infrared Survey Explorer (WISE) telescope. The volunteers then just look for moving objects. https://www.zooniverse.org/projects/marckuchner/backyard-wor...
unzadunza··on What Is Nix?
I don't know if it's beautiful, but here is one of mine.

It sets up me as a user: https://github.com/cswank/dotfiles/blob/master/nix/configura...

Sets up a hobby app I built via systemd: https://github.com/cswank/dotfiles/blob/master/nix/configura...

Defines a cron job that backs up my music files: https://github.com/cswank/dotfiles/blob/master/nix/configura...

Opens up ports in the firewall (they are all closed by default): https://github.com/cswank/dotfiles/blob/master/nix/configura...

The rest is pretty much boilerplate from the default configuration you get when starting from scratch.

unzadunza··on Why introductory chemistry is boring: a long-term historical perspective
I think it all comes down to the instructor. I took Organic the 1st time with a semi-famous professor who didn't want to be there and just sat next to an overhead projector and wrote down formulas for us to memorize. Boring! I squeaked by with a C. When I had to take it again for grad school because I failed the organic part of the entrance exams (imagine that) I had a completely different experience. The instructor obviously loved to teach and she taught us the principals as to why A+B=C rather than just memorizing. I loved that class and got an A.
unzadunza··on How Scientists Got Climate Change So Wrong
Speaking of consensus, someone happened to post https://stephenschneider.stanford.edu/Publications/PDF_Paper... (2003) today, in which it is argued that consensus science is not science at all.
unzadunza··on What Shape Is the Universe, Closed or Flat?
I read a book a long time ago (Poetry of the Universe: A Mathematical Exploration of the Cosmos, by Robert Osserman) about the shape of the universe. In it he talks about quasars. If you observe 2 of them in opposite directions, each 13 billions light years from earth, then they must be 26 billion light years from each other. But the universe is only a little less than 14 billion years old so how can this be? He argues that the universe must be a hypersphere.

I read this more than 20 years ago, and I'm no cosmologist, so forgive me if I butchered that summary.

unzadunza··on Tourists Heeding Utah’s ‘Mighty 5’ Campaign Overpower Moab
“No more cars in national parks. Let the people walk. Or ride horses, bicycles, mules, wild pigs--anything--but keep the automobiles and the motorcycles and all their motorized relatives out. We have agreed not to drive our automobiles into cathedrals, concert halls, art museums, legislative assemblies, private bedrooms and the other sanctums of our culture; we should treat our national parks with the same deference, for they, too, are holy places. An increasingly pagan and hedonistic people (thank God!), we are learning finally that the forests and mountains and desert canyons are holier than our churches. Therefore let us behave accordingly.” ― Edward Abbey, Desert Solitaire
unzadunza··on Paradise Lost: How Tourists Are Destroying the Places They Love
I had to create an account just to agree with you. I express the same opinion to my wife and whoever else will listen and so far every single one of them get mad at me. I just don't understand the attraction of traveling to some country where it's clear that most of the people don't like you. You are not alone.

However, there was that one time we went to Ireland and were the only Americans in a bar and the band found out we were from Colorado and played John Denver's "Rocky Mountain High" and the whole bar was singing along. That was one of the best nights of my life. So I guess it's more complicated than just saying "traveling is so overrated it's insane".
