q845712··on Plans to plant billions of trees threatened by undersupply of seedlings
In all fairness it's really hard to make money off of "reduce" and "reuse," and we've decided to use money as the system for allocating all of our resources.

q845712··on Is shareholder capitalism a suicide pact?
> the growth obsession is a product of the Reagan-era

I hear you, but uncle Karl names and shames the growth-obsession in Das Kapital which predated Reagan by over 100 years. It's a part of the system that many people have incentive to deny, hide, or minimize, but endless growth seems to be a requirement of "the system of organizing our resources that prioritizes turning capital into more capital" aka capital-ism.

q845712··on Is shareholder capitalism a suicide pact?
It feels a little inevitable though, given the other rules of the system: Companies don't become more valuable by having a steady earnings forecast, they become more valuable by having an _increase_ in earnings that is forecast to continue increasing. How can everything always increase? Well when you reach market saturation on one product, start a new product in a different market. What if all the markets seem saturated? Find a new thing to commoditize, a new market to create... Any system where unlimited growth is rewarded is going to try to take over everything it possibly can.

q845712··on 2048 Bit RSA and the Year 2030
I mean like the incentives aren't aligned. So maybe you're giving an example but i'm honestly not sure. :)

in the space of cve or malware detection, the user wants a safe/secure computing experience with minimal overhead, but the antivirus / cve-scan vendor wants to claim that they're _keeping_ the you safe. so they're motivated to tell you all about the things they scanned and possible attacks / vectors they found. You probably would've been safe responding to only a subset of those alerts, but they have no incentive to minimize the things they show you, because if they ever missed one you would change vendors.

in the space of cryptography, the user wants secure communications that are unbreakable but with minimum hassle and overhead, but the advisory boards etc. are incentivized to act like they have important advice to give. So from the user perspective maybe it makes sense to use 2048 bit encryption for a few more decades, but from the "talking head" authority figure perspective, they can't afford to ever be wrong and it's good if they have something new to recommend every so often, so the easiest for them to do is to keep upping the number of bits used to encrypt, even if there's 99.99% odds that a smaller/shorter/simpler encryption would've been equally as secure.

q845712··on C++23: The Next C++ Standard
I could be wrong as I was young and not yet in the field, but my impression has always been that sometime in the 80s/90s as the whole "networking, world wide web, wowie!" moment happened, there was this idea that "maybe on a local computer everything is files, but on the network everything is streams. Hey, maybe everything is streams!?" and C++ just happened to be creating itself in that zeitgeist, trying to look modern and future-thinking, so somebody decided to see what would happen if all the i/o was "stream-native".

IDK, it'll probably make more sense in another 15 years as we clear away the cruft of all the things that tried to bring "cloud native" paradigms into a space where they didn't really fit...

q845712··on 2048 Bit RSA and the Year 2030
I have no specialist knowledge in this subfield, but after reading the article's arguments that basically if you could sic the entire bitcoin network on 2048 RSA it would take 700+ years, I have to wonder about perverse incentives.

Another thing that's missing is the lifetime expectancy, e.g. "for how many years does something encrypted in 2030 need to be unbreakable?"

The author doesn't seem to be a big authority, so has little to lose by staking their reputation on "you don't need it to be that good," whereas by the very nature of their authority, anyone in the resource you link is going to be motivated to never be wrong under any circumstances. So if someone with some reputation/authority/power to lose think there's a 0.001% chance that some new incremental improvements will allow for fast-enough breaking of 2048 bit encryption created in 2030 within a window where that would be unacceptable, then they're motivated to guess high. The authority in this case doesn't directly bear the costs of too high of a guess, whereas it could be very bad for, i dunno, some country's government, and by extension the org or people that made that country's standards recommendations, if some classified information became public 15 or 50 years earlier than intended just because it could be decrypted.

q845712··on Closure, from why the lucky stiff (2013)
I said this elsewhere too -- while in general I like things _like_ the poignant guide, and appreciate its existence, I never actually finished reading it.

To me it's an interesting touchstone work showing/reminding that the "invisibly neutral" tone we've collectively adopted is still an editorial choice and cultural moment.

I'm sure writing and communication styles will drift back and forth over the next few decades. Sometime soon (if not already) another generation of younger developers will coalesce around some document that feels authentically counter-cultural, like their own late-night jokes and dreams have been given just enough coherence to hook them in, and then I probably still won't get it because I'll be out of touch.... :)

q845712··on Closure, from why the lucky stiff (2013)
Honestly at the time I remember getting weird twee/precious vibes from the Ruby community and I wasn't particularly interested in it or Rails. I only discovered _why's poignant guide later after I had to learn Rails on the job, and to be honest I never finished it.

I still strongly prefer the worldview, circumstances, mindset, etc. where that kind of content is written, read, and celebrated over today's focus on Influence and Professionalism.

q845712··on Why is desalination so difficult?
it's probably a good starting position to assume that since we all the share the same closed-ish system called planet earth, there's interconnections between different systems. Certainly the border areas between desert and not-desert aren't very crisply defined. Certainly (reference in other threads) nutrients can be blown by the winds from desert into non-desert areas far away. Certainly there exist some animals who go in and out of desert regions (birds, butterflies, ...). It's a really good idea to assume that things on this planet are connected to each other.
q845712··on Anti-ageing protein injection boosts monkeys’ memories
"animal models" is a fairly standard phrase in research: When people research depression, alzheimers, cancer, etc., they generally start with mice and work their way up through monkeys before coming to human trials. For many conditions there's specific "lines" of mice that have been bred or even genetically modified to exhibit those conditions in a reliable or extreme way. Depression is particularly challenging since you can't ask an animal how it's feeling, and frankly nearly all animals used in laboratories are understimulated, removed from their natural habitat, and probably a little "depressed". (see e.g. the "rat park" studies (https://www.psychiatrictimes.com/view/what-does-rat-park-tea...) that showed that rats were much less likely to self-administer cocaine if they were in an environment that let them have a more enjoyable/fulfilling/natural life otherwise.)

So anyway "animal models" just means "an animal mice/rats/monkeys/etc. that we have decided has enough of the same symptoms of the human disease that we can use it to study treatments of that disease", and it's fairly common for something to work in mice but fail in monkeys, or even to work in both mice and monkeys but not work or have very undesirable side-effects in humans. (side note: one of the least discussed things in pharma is how they source the first humans for trialling a new treatment, which does carry non-trivial risk to the human "guinea pigs" - it's generally people who are poor and desperate.)

but there's a premium on our youth -- The people who complain that it's harder to find a job in their 50s and 60s can't _all_ be wrong or mistaken. I feel like we like to imagine that these treatments would extend our 20s and 30s, but what if they extend our 60s instead?

q845712··on A one-person oral history of Geocities HTML Chat (2022)
Geocities HTML chat was my first chatroom experience. IIRC my friend found it because they had purchased "chat.com" and had it forwarding to some chatroom? But I could be wrong about that honestly, curious if anyone else remembers.

I did pay it an homage at a couple of points, before slack completely took over, by writing a simple unsanitized HTML chatroom, hosting it on my own work computer, and telling my coworkers to all go to 192.168.x.y/chat or something -- the kind of thing you can do at small companies when you only have a couple dozen coworkers. It was incredibly entertaining to me (and some others) and I did it at two companies, but I was a little surprised that nobody ever said "hey this reminds me of geocities chat"!

q845712··on Suit alleges recreation.gov cluttered with junk fees, seeks millions in refunds
as someone else is already saying -- Arizona basically already has this for DMVs. There's a parallel system of privately owned and operated offices where you can make an appointment to e.g. get your drivers license. You show up right around your appointment time, there's somebody ready to help you within minutes, and everything is streamlined / easy. Most pleasant experience I've ever had of getting a license in a new state. In that case it was never clear to me whether I paid extra for the private service or not, but whatever I paid seemed unremarkable.
q845712··on Messages that can only be understood under the influence of psychedelics
check section 3 of this review: https://www.asc.ohio-state.edu/golubitsky.4/reprintweb-0.5/o...

or for a narrower slice this paper is reference [6]: https://www.researchgate.net/publication/11500666_What_Geome...

The full mathematics are quite challenging, but the gist of the result (iirc) is basically: many common hallucinatory experiences, including the geometric patterns reported from both psychedelics and migraines, can be explained by the inherent connectivity patterns in the visual cortex. Consistent with this idea, there's other strains of research (sorry, too lazy to look up more citations) that show that psychedelics tend to decrease input from the primary sense organs, so that during a trip we really are literally turning inward. (if you want to look it up, iirc the effect is called "thalamic gating" or something? the senses all come up the spinal nerves into the thalamus which helps gate our attention, but during psychedelic experiences all thalamic input is turned down.)

So what happens when you turn down the dimmer on external senses, is that you "see" only from the "higher" cortical areas: suddenly the neurons that are several synapses removed from primary sense activity are the 'loudest' in our experience. This is why "set and setting" are so important in a trip, because you're going to literally experience your mood and emotional state more strongly than usual, since it won't be mediated as much by external sensory events. That's not to say there's no external senses- most people report experiencing a sort of psychedelic remix of ordinary reality. But back to the geometric patterns -- sometimes what you see really does seem to be based on the fundamental connectivity matrix. it's like in absence of strong input, the visual cortex just has activity rippling across it along its own wiring.

anyways hopefully this rambling with a few sources cited helped a little.

q845712··on The Rise and Fall of Getting Things Done (2020)
:) it is also a big part of buddhism. IMO the intersections between several systems are very interesting as they tend to be the most fruitful even if pursued without the context of the rest of the system (ie if you think you can cherry-pick the good parts out of a religion or philosophical system, start by looking at where many of them agree)
q845712··on The Rise and Fall of Getting Things Done (2020)
Just sharing my own experience, but the more time I've spent contemplating death the easier time I've had with it: Every beginning implies an end. Every birth and growth implies a decline and death. All coming-together results in eventual separation. Etc.

IMO there's nothing wrong with finding the beginnings more fun and enjoying the fun parts, but part of what prevents us from moving towards utopia is a blindness to the whole cycle, an unwillingness to engage in the difficulties of endings and change. This isn't to say we need to celebrate "the end" either, but just that in some sense, contentment _is_ utopia, and contentment requires making peace with both beginnings and ends.

q845712··on Am I the Unethical One?
depends on the situation but generally most people aren't that enthusiastic to be your UX guinea pigs, and it isn't that much fun to administer the same test so many times in a single day (think of how bored your optometrist sounds as they ask you which lens is better). I worked at a shop that had a target of 3-5 users for any given UX testing because usually it starts to get repetitive after that - you tend to hit the diminishing returns portion of the curve.

So if you assume that the UX tests were short (20-30 minutes) you're still talking ~15 total hours spent on UX testing, or two full work days. That would be a surprising amount of time.

As someone else said, it's conceivable that they ran very short studies on a large number of people in the context of having a party or a couple of small gatherings, but it does seem unlikely overall.

q845712··on Researchers treat depression by reversing brain signals traveling the wrong way
I was hoping you were going to link to a DIY tms, so i will: https://www.instructables.com/Transcranial-Magnetic-Stimulat...

Note the disclaimers, especially "TOUCHING THE DEVICE WRONG DURING ASSEMBLY CAN INSTANTLY KILL YOU. THIS DEVICE COULD KILL YOU OR MAIM YOU OR BREAK YOUR MIND."

However the other things you're posting are alternative chemical treatments. People with resistant depression have already tried the approved chemical remedies. While I broadly agree that there's evidence in favor of both psilocybin and ketamine being potent chemical anti-depressants, I also think there's a number of valid reasons for someone to reach a point where they don't want to try any other chemical remedies, and ECT / TMS become more compelling options.

q845712··on Rational Magic
in the interest of pluralism and live/let-live though: I've found it more rewarding and interesting to learn and participate in some relatively ancient rituals than to track and attend sports games. I don't think these things need to be exclusive, and in fact it's kind of great that there's a diverse set of offerings that appeal to a diverse array of people. Of course, one hopes that we mostly recognize that we're mostly after the same or similar things, rather than talking derisively about "ball sports" or "candle ceremonies."
q845712··on Rational Magic
I'm not a proponent of either, but as I understand creationism there's a "divine plan" and as I understand simulationism there's just a "vast parameter search" so imo being inside a simulation would be disappointing to someone who wants an activist/interventionist/personally-interested creator-god.
q845712··on Rational Magic
imo part of the goal is to convince you that "reason" is ...

- an illusion

- an affectation of the bourgeoisie

- an incomplete and imperfect tool

- only effective within a limited and hard-to-bound domain

- a tool of oppression

- capable of being claimed or colonized by any number of objectionable belief systems

q845712··on What if we covered every warehouse in the mountain West with solar panels?
it seems easy to undervalue undeveloped land. I think the argument being made is that we have land that's already connected to the electrical grid, already has roads and routes for servicing, already has fire mitigation and contingency plans in place, already has disrupted whatever ecological processes would have been happening if it were left undeveloped, and is just missing the last piece of solar panels, which we may as well add since we've done the rest of the development process.
q845712··on Public Money, Public Code
> > Open sourcing code is also extra work that has to be done and will make the software more expensive to make and maintain.

> Not if there is an established standard and practice of writing code in an open source way.

I've worked on closed source corporate software most of my career and then primarily corporate-sponsored open source in the last two years. In my own limited experience, it is strictly less work to have closed-source software. There's less concern / hesitations / hand-wringing over mover quickly when you have the illusion of privacy, and relatedly having a requirement that (almost) everything (eventually) becomes public only adds steps. Certain things always have to happen privately (examples include: internal discussions that include organizationally privileged information, certain CVE handling steps, fully secured builds with proper corporate attestations, and internal project-tracking) so you wind up with a private set of systems to maintain as well as the public ones.

Maybe there's some orgs out there that "do it right" in terms of having OSS projects not add overhead, but I doubt it's possible in orgs with as much need for privacy and security as most fortune 1k co.s and governments.

q845712··on Framework Laptop Cupholder Expansion Card
YMMV but both my macbooks occasionally display evidence that they were awake while they were asleep (e.g. if i close the hing at 10pm and open it at 8am, it might show 2:14am for a few seconds before catching up, but also they show new unread messages even before connecting to wifi). Weirdly my 2013 macbook is much much better at going to sleep and waking up with nearly the same battery capacity, whereas my 2019 (work laptop) will often run down 15-40% of its battery over the weekend while completely closed.
