tony_cannistra··on Ancient Greek terms worth reviving
I have been several times confused by the word "arete" - because in French (arête) it's a kind of rock formation and has been taken up by the rock climbing community, and in Greek (ἀρετή) it's "excellence."

There's a coffee shop near me, attached to and co-operated by a climbing gear store, called arête. The proximity to the climbing store suggests one interpretation, but it is an excellent coffee shop.

that's pretty short for a "heyday," IMO.

tony_cannistra··on How Facebook and Instagram became marketplaces for child sex trafficking
Look, it's clear you don't like Meta. Frankly neither do I. But the reality is that the article at the URL that you linked in your original comments contains evidence that supports my point that PR is all that matters.

Namely: "KrebsOnSecurity later found that reporting the abusive Facebook groups to a quarter-million followers on Twitter was the fastest way to get them disabled."

Frankly it does seem that you don't appear to have read or understood the information presented in the link you posted.

tony_cannistra··on How Facebook and Instagram became marketplaces for child sex trafficking
This is nonsense.

It is obvious to me that any bad PR is orders of magnitude worse for the business than the potential benefit of having even hundreds of thousands of criminals "engaging" on the platform.

Not sure what you think about this, but I'd wager that this fellow posted his detailed architecture diagram for transparency and maybe even to solicit some constructive criticism or feedback.

It sounds like you'd be well positioned to offer some feedback, but I'd recommend against that without your practicing some empathy for the stage he's in with his education.

tony_cannistra··on Pirate Weather
Yeah, they do actually. There's a bar at the bottom with the time on it.

windy.com is a good one for that.

I love the attitude of this guy. From the "Background" section:

> "This project started from two points: as part of my PhD, I had to become very familiar with working with NOAA forecast results. Separately, an old tablet set up as a "Magic Mirror,” and was using a weather module that relied on the Dark Sky API, as well as my Home Assistant setup. So when I heard that it was shutting down, I thought, "I wonder if I could do this.” Plus, I love learning new things, and I had been looking for a project to learn Python on, so this seemed like the perfect opportunity! Spoiler alert, but it was way more difficult than I thought, but learned a lot throughout the process, and I think the end result turned out really well!"

tony_cannistra··on Show HN: An all-in-one app designed for deep work and to build atomic habits
This surprised me too, and not in a good way. I got that scary old feeling from the early-2000s when a surprise exe appeared.
tony_cannistra··on Who Blew Up Nord Stream? Investigators Focus on Mysterious Passengers on a Yacht
I won't lie, I'm a little envious of whomever secured the undoubtedly very exciting job to plan this whole thing. Every new emergence reads like a scene in a movie. I can imagine the scene where the sailboat pulls up in tiny, unsuspecting Wiek and gets loaded with explosives in the middle of the night.
tony_cannistra··on 20% of Sierra Nevada conifer forests are stranded in habitats that are too warm
perhaps more ergonomic to use in the context of a population of trees.
tony_cannistra··on 20% of Sierra Nevada conifer forests are stranded in habitats that are too warm
Original scientific article: https://academic.oup.com/pnasnexus/article/2/2/pgad004/70590...

This work is part of a larger body of research that seeks to understand whether organisms (like these conifers) will be able to respond to changing environments in a way that avoids their extinction. It is particularly interesting to study in vegetation, where movement is limited by dispersal and reproduction.

A frequent limitation to these studies, which this one shares, is that often it is assumed that these conifers' future climatic "ideal" (known as their "niche") is static, predicted by their historical niches.

However, there are several modalities among which conifers may change their climatic niche that we may not have been able to observe yet, namely: phenotypic plasticity and evolutionary adaptation. We don't know very much about how conifer species exhibit plastic responses to environmental stress, nor about how evolutionary adaptation may enable conifers to exist in novel (to them) environments.

These studies are useful, but as usual should be taken in light of their limitations.

tony_cannistra··on Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners
There is a pricing section on the website.
tony_cannistra··on Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners
not OP. My understanding is that situations like these really require installation of the (IMO, ugly) wall units ("mini-splits").

Current air-source heat pumps can't produce hot water at temperatures necessary to drive radiators.

tony_cannistra··on Launch HN: Electric Air (YC W23) – Heat pump sold directly to homeowners
The holistic approach is nice to see.

There are obviously already several major players in the industry (notably, Mitsubishi, but also more "DIY"-focused brands like "Mr. Cool") offering heat pump systems with air handlers, such as this.

But this approach seems to be much more integrated in ways that actually might make a difference.

tony_cannistra··on The tech downturn seen through Hacker News comments
That's interesting. To me it actually looks like the opposite. The share of remote work eligible postings as a fraction of total postings seems to be higher than before?
tony_cannistra··on Junkyard computing – repurposing discarded smartphones to minimize pollution
I'd imagine you're asking like, how did they _physically_ do it? That is an interesting question, I'd love to see pictures.

But from an infrastructural standpoint I'd imagine that just putting a bespoke Linux distro on each of the phones and connecting them to the same network would enable the same kinds of orchestration you'd do in a "regular cloud."

tony_cannistra··on Low Antarctic continental climate sensitivity due to high ice sheet orography
> the model seems to be just simple buffering: lots of sub-freezing deep ice can absorb lots of heat without appreciable changes in surface temperature.

Sorry, but I don't think you've interpreted the study well. You're right about the lack of interior warming - that's the premise of the study. But the study attributes this to the orographic effect of the relatively high elevation of the Antarctic Ice Sheet (AIS) - not any effect of heat buffering in the ice.

To determine this, they "flattened" (e.g. removed all influence of terrain from) the AIS, and ran global climate models over this modified terrain.

They determined that the terrain _itself_, which is the progenitor of orographic effects in the atmosphere, was responsible for the lack of interior temperature rise. Orographic effects at synoptic/continental scales can have a substantial impact on latent heat transport – they showed that here.

Perhaps thermal buffering has a place in the conversation too, but it's not mentioned in this paper.

tony_cannistra··on Netflix has job with almost $1M listed salary range, to comply with new CA law
Maybe, but I don't buy that a FAANG would hire a fresh-out-of-school grad at L5 with a $90k salary.
tony_cannistra··on Netflix has job with almost $1M listed salary range, to comply with new CA law
Yes it is.

Perhaps Netflix is not _breaking_ a law, which itself may have been written by "dilettantes", but this action certainly disabuses us of the notion that Netflix has any intention to adhere to the spirit of the law, which was to reduce racial and gender-based salary gaps.

tony_cannistra··on Netflix has job with almost $1M listed salary range, to comply with new CA law
Colorado has a similar law, but I've never observed this kind of "range-hacking." Why would this happen in CA but not CO?
tony_cannistra··on Netflix has job with almost $1M listed salary range, to comply with new CA law
You're right but I think you're missing the point. Offering a range that broad in the job listing is just an effort to flaunt a law. That law was put into place to help the people you're talking about.

tony_cannistra··on ‘Wealth is a curse’: Hobby Lobby founder says he’s giving away his company
I'd say a move toward a co-op would be too risky of a step for a billion-dollar company. The whole intent behind the Patagonia decision was to dethrone shareholder primacy while still maintaining some control / centralized governance.
tony_cannistra··on ‘Wealth is a curse’: Hobby Lobby founder says he’s giving away his company
As with the the Chouinard / Patagonia situation, the "giving away company" line is unfortunately just another example of bad headline writing.

One really must examine the individuals making this decision + their track record before we make judgments about the merits of this choice for folks other than the family. Does Yvon's track record with Patagonia align with my values and make me trust his choice as being truly "beneficial" for the planet? Yes.

Did the Chouinard family also avoid $700 million in taxes by "giving away the company" (e.g. putting the shares in one or more trusts, like Hobby Lobby family will). Also yes. [0]

tony_cannistra··on Tesla stock falls again, toward longest losing streak in more than 4 years
They have?
tony_cannistra··on Paper-Thin Solar Makes Any Surface Photovoltaic
As they mention in the article though, there are lots of applications that aren't space-limited but are structurally-limited (warehouses) in that they can't support the weight of solar panels without more engineering.

I did think it was strange that they obfuscated the W/m^2 statistic by only presenting W/kg and kg/m^2. I suppose focusing on watts per kilogram better aligns with a breakthrough in installations with poor structural support for heavy panels.

tony_cannistra··on Doors of McMurdo
I was thinking about this playing Cities Skylines today. I feel like I hate "master-planning" things when I start the game, but then my cities end up being chaos and needing lots of demolishing to fix broken stuff.

I might just be bad at Cities Skylines.

tony_cannistra··on Overture Maps Foundation
This is particularly true for governments. I know the United States Geological Survey wanted to use OSM data for portions of their cartography, but can't because it's not public domain (as their products must be).

Not OP, but in my experience:

Jupiter Intelligence (https://jupiterintel.com/)

Descartes Labs (https://descarteslabs.com/)

Microsoft Planetary Computer (https://planetarycomputer.microsoft.com/)

Coiled (managed Dask - python HPC) (https://www.coiled.io/)
