I'm not sure this is a useful framing.

If the chemicals used to make an aerogel are carbon sinks, the aerogel will be as well unless the energy use is higher than the sunk carbon.

If it's not biological, it's usually not a carbon sink. There are exceptions.

And as for outgassing, in my experience any polymer that you do gas sampling over in a closed container will be show some offgassing of something. It's just the nature of solids to release vapor, if there is zero in the gas phase then there's a lot of entropic force to drive there to be at least one in the gas phase. Like, a huge entropic driving force. Everything outgasses.

Whether there's a lot of outgassing depends on the chemicals that are broken down and the volatility and the temperature, I think this will almost always be low but measurable for long chain polymers, and modest for short chain and low density polymers (think how foam insulation smells when it gets heated in the sun if you've ever seen it). What is outgassed is definitely more important, so it really just is super case by case to do an actual safety analysis to compare them, and it would depend on the use conditions (temperature, sunlight, etc).

I don't know anything about jsmol or pymol, I don't think a software suite is necessary here. These processes are pretty basic and you can just look up relative volatilities and breakdown products for a given case. You definitely don't want to try to simulate the thermal breakdown of a polymer (which you'd define statistically with potentially hundreds of thousands of atoms each) -- especially not quantum mechanically -- into the gas phase. There are a lot of opportunities for much more basic issues than software libraries; like how you model the gas around the solid surface and what the structure of the solid surface is. Does gas move due to outside flow? Does it also carry away heat?

It's a hugely complex thing to actually calculate (and even for a few atoms QM simulations are horrific and easy to mess up) so instead I personally would just rely on the rules of thumb I talked about first and then look up actual data from bulk materials property measurements. I definitely wouldn't touch a simulation when real bulk property measurements are easily available.
I do think the question of "how should bots that do static analysis work" is an important one, but in the meantime, people are gonna bot and repo managers are gonna complain.
Doesn't pretty much all closed-source proprietary software prohibit reverse engineering and redistribution?
If you eat meet which has been raised on ground where trees have been felled for the sole purpose of creating that meat then yes the amount of carbon released is going to be insane. Here in the UK (nearly?) all the meat we consume is grown nationally, i.e. doesn't originate from places like the Amazon.

And on the methane front, they eat the carbon in the grass which has literally just captured a bit of carbon from the atmosphere. They fart it up and then it comes back down in a reasonable period of time and goes back into the grass they are grazing upon.

The cycles and definitely complex and opaque but we need to get better at working with nature rather than engineering new ways to ignore the real issues.
Furthermore, collapse doesn't happen everywhere the same, nor all at once. It's more like things break down slowly, and never get fixed rather than explosions on the street, until one day you are a third world country.

And third world countries still have very nice neighborhoods, and very rich people. But everything around gets much worse.
You know, it's kind of amusing to see people shout inflation inflation but really, the only things that are consistently getting more expensive are monopolies or pseudo monopolies (tuition, healthcare). Instead of everything falling apart, I my opinion we are very close, so incredibly close to getting everything right and everything working out in the end.

Imagine if housing wasn't such a drag. Would there be so much to complain about?

Healthcare? It's a nonissue in Germany. People get a perfectly reasonable amount of healthcare. Americans might insist that doctors shouldn't be overbooked or something but arguing how the boomers had better healthcare is ridiculous.

Tuition? It's only a problem if you want it to be. If the degree gets you a job it's worth it, if not then seek a cheaper college.

What educational materials are you referring to? In Florida, the responsibility for choosing educational materials, negotiating with publishers, etc, was at the school district level.

Schools need to adhere to the Common Core subject areas, but what materials they use in teaching that was up to the district.

Recently, Florida's state-level Department of Education has been restricting the textbooks that school districts can use, but this is more of a reject list, than an accept list.

I vaguely remember computer magazines in the early 2000s talking about that: some lawyers suggested that EULAs were of questionable enforcability because they were negotiated solely by one party with legal resources and signed by one party without. The general status quo seems to have been "make threats and settle out of court" ever since, avoiding any sort of legal precedent being set.

I'm not a lawyer, so perhaps I'm unaware of a high profile case where such a thing happened, but as far as I'm aware EULAs are very similar to the state of DMCA takedowns: widely used as a cudgel against the little guy, since most people don't have the resources to fight it out in court, and in the rare cases of resistance they go for an out of court settlement.

Indeed, if "{value} is bad" can be automatically f-stringed by an external program automatically --- then why can't Python do this automatically -- so we can get rid of the f-string type as a required explicit declaration? After all, we don't specifically add a type to a number like 42 or 3.14159 --- those are implicitly 'int' and 'float' types.

I would use such a feature, as I always use f-strings when formatting.

There's a book, "Nonviolent communication: a language of life", 3rd ed, which writes about this.

From what I remember, if you can talk and listen to the kid, and understand what underlying needs drive the behavior, and then mention this to him -- then he'll feel understood, and notice that you're listening and care. And that was, from what I remember, the most important thing, in solving a conflict. (I.e. being listened to and understood.) The other things then, afterwards, tended to be comparatively simple to solve together.
I know it is pre-tax. I also know that there are benefits in Europe that simply do not exist in the US - minimum of 25 days of actual vacation and not that "you may travel for a few days, but you are still on-call" thing that people in the US call "holidays", Elternzeit, etc...

But still, no one would claim that is easy to get a 90k€ salary in Germany, or that "if you are not asking that much then what are you doing". For 150, you have to be way above average or you have to running your own business.
Ok, but my question was for more detail on how such an appraisal would work and then what the second order effects would be. For something this big we need to think through several generations worth of downstream consequences. We already have many examples of how such revolutionary economic changes can lead to disaster and mass death when people get caught up with the spirit of the idea and don't sit down and do the hard math to work out all of the details ahead of time.
I don't think we disagree, but what you describe is not necessarily a result of collusion -- maybe the business just doesn't work with higher-paid workers (i.e., product costs more than market is willing to pay) and scales with number of workers, in which case the owner might take whatever workers they can get at cost X, but can't hire any at cost X+1.

Only a profit-averse business owner would turn away revenue-exceeding-costs work merely because it involves paying workers more -- that business will likely not last super long unless there are special circumstances in play.
I don't even put much faith in those. I've seen enough that I was sure they were BS... they're just noise to me.

That's pretty sweet, but it's an entire additional layer of unnecessary complexity. Plus it still requires everyone to implement a new protocol into their apps. Why not use one purpose-built for it?

Also, WebSockets bring some nontrivial complexity. This can bite you with things like proxies and custom backends, which have to implement a special code path from normal HTTP to handle WebSockets.
I'm still not sure I'm understanding you. What I'm asking about is the question of compensation conditional on experience and skill being identical. So by definition, I'm taking experience/skill differences out of the picture. So we have

Alice: backend engineer in London, able to get $120K from UK companies
Alicia: backend engineer in NYC, able to get $250K from US companies

with identical skill/experience. And we say for the sake of argument that cost of living is identical in London and NYC.

Now suppose Alicia's company wants to hire Alice.

Certainly, I agree that it makes perfect sense in a free labor market for the US company to try to get Alice for $120K.

But the company I work for (a well-known US tech company) makes many claims about how "fair" its compensation program is. So what I'm inviting you to discuss is whether or not that company would have a hard time making an argument that adjusting according to the local labor market is actually "fair".

Essentially, Alice is being penalized for happening to be in a locality where her skills are valued less. But that is out of her control. Would it not be "fairer" for a company to adjust compensation as follows:

1. Firstly, according to skill / experience

And then, either

2a. That's it, end of story: skill / experience only.

or

2b. By local cost of living, within equivalent skill levels.

> Their parents bought houses in rural suburbia.

I bought a 3,000+ sqft house in a desirable part of my city 5 years ago. My friends spent 10% more money 1 year ago and got a 1,800 sqft house that's newer, recently renovated. It's a few blocks away.

This is not an issue of generational expectations. Prices for the same type of house with the same standard of living have skyrocketed compared to real income.

I wonder if Robinhood could have changed their GME margin requirements?
Not sure if that's allowed, but surely that would have allowed them to unwind some (margin call everyone who is leveraged long), and some customers who were willing to put up 100% to cover their GME buys could keep buying.
Thanks both for a thoughtful discussion.

Just one important nuance -- VCs like me who come in early and stay with portfolio companies for 5-10 years are both on the "buy" and "sell" side of the market.

So yes, a slower VC funding environment does impact valuations favorably for VCs, for net new investments (the "buy" side), so I'm talking my book to some extent.

BUT net new investments is only a part of the job (<50% for sure) for a VC like me. Most of my time is spent working with my existing portfolio (sitting on boards, etc). And a harsher environment is bad news for my existing portfolio (and/or anyone's portfolio), and me (and/or investors like me) as a result. Like a lot of VCs, I've looked like a "genius" for the last couple of years as many of my investments became unicorns, with huge paper markups. Now it's likely that the pace of markups is going to slow down significantly. Perhaps we're entering a world of flat valuations - or even downrounds? No markups is not a good look for VCs - makes it harder to raise the next funds, etc.

So yes, in the long term, it's good for VCs if we're able to invest in (the right) companies in the 2022-2023 cohort at lower valuations. But that will take 8-10 years to manifest into concrete results, by the time those companies become very big. In the meantime, VCs won't have a lot of fun navigating a flat round/downround environment (if it does indeed materialize) with their existing portfolio.

> This is another way of saying Robinhood did not have the capital reserves required to fulfill their obligations as a broker-dealer to their customers.

That's basically how the entire financial system works. You're supposed to be able to withdraw deposits as cash, but if everybody does it (from say, an internet meme event), the banks obviously wouldn't be able to "fulfill their obligations [...] to their customers". It's also unreasonable to have 100% of deposits as cash on hand on the unlikely chance that occurs.

>Also, it is not correct that they "didn't have enough money to buy GME". Restricting trading of GME was a choice they made to post less collateral, which they didn't have.

I don't get what distinction you're trying to make here? That "money" doesn't mean "collateral"? Those seem fairly interchangeable in this context.

One feature a few of us toyed with for years that I'd love to see tried seriously someday (or does it already exist?) would be intelligent tag trees or maps that stuff could be plugged into, ideally that could also be shared and mixed too. More specific tags would have parent/child/sibling relationships with more generic tags, and a single tag would then pull in all the others as far as searching. So for example if I have a photo of one of my cats, and I tag it Cat Name having set that up, "calico" or "tabby", breed, plain old "cat" and anything else associated with the specific tag would all be hits. And up the stack, if I tag a picture "calico" it should show up under the "cat" tag as well automatically with no further effort. Conditionals could be incorporated too, like if there is a character who in a series has long hair, tagging "short hair" could automatically pull in "alternative hairstyle".

My big problem with typical tagging is that it's a lot of grunt work to be comprehensive. AI can help but has its own issues. While getting the UI/UX right would take some work, a universal system-wide multi-dimensional tag map could allow a lot more metadata a lot more easily. Even more so with sharing, communities could curate tag maps around areas of interest and one could stay synced with tag maps of "aircraft" or "trees" or the like which would bring in lots of technical depth to explore in a distributed fashion. Eventually maybe community AI recognition models could be an optional part of that too to help identify specific given subjects (and one would be free to then not have other kinds of things identified or shared).
I grew up in the US, my parents are very blue collar, neither of them went to college, and they worked hard to give me and my sibling a decent childhood. I went to the cheapest college I could (a local university you've never heard of) to get a BS in Computer Science.

I worked my ass off, grinding on interview studying, working internships and jumping companies whenever I could get a better offer. I'm about to turn 30 and I made 430k (200k of which is salary) in 2021 working at a big company in the US.

I would not consider my background to be particularly privileged and I don't consider myself to be all that smart, but I managed to get here just by working hard and never getting comfortable. Yes, if you get comfortable in the first tech job you land and just sit around enjoying your life, then you probably won't naturally end up in a place making lots of money.

Obviously being privileged and getting everything handed to you makes landing a nice cushy job much easier, but there are still plenty of paths to these high paying jobs if you're willing to work hard.

Also, as mentioned by another person in this thread, this totally does take a toll on your mental health and you absolutely have to sacrifice things. I gave up a lot of things that would have given me a better quality of life, but those were choices I was willing to make.
