Let's not be so dramatic as to say that the general aviation fleet is single handedly responsible for poisoning the world with lead.

When leaded car gas was still in use it resulted in 4-5 million tons of lead emissions per year.[1]

The use of leaded aviation fuel contributes 500 tons per year according to the EPA[2]. Compared to 5,000,000 tons for cars historically.

Of course, any lead is not good and we should be shooting for zero. Which is the goal of the unleaded G100UL aviation fuel. But let's not try to say that personal aviation is evil when it's contributing a fraction of a percent of lead contamination. Frankly, we have bigger pollution problems to worry about than a very small amount of lead emissions from an ever shrinking fleet of piston powered aircraft.

Mind you that general aviation is more than rich people flying around in their planes. It's medical flights, it's training future airline pilots, it's aerial surveying, and many more critical tasks for society.

The cost of imprisoning people is subsidized by the government. Who profits off of their labor though?

When my mother was in prison she worked for a private company for well below our states minimum wage. So her employer profited off of her nearly free labor.

I rather like the first article. It resonates with my own perspective on the absurdity of some steps in the Drake Equation which seems to assume that there should be some kind of deterministic drive towards exactly our kinds of technology.

If nothing else, for me this resolves the Fermi Paradox in a satisfactory manner. We don't find aliens, because we are not really looking for aliens. Just for a glimpse of ourselves in a cosmic mirror.

I guess that's what can happen when you stare into the Rule 30 abyss for 40 years.

Can you elaborate? How is critical theory affecting the policy advocated by left wing political candidates? Which left wing ideology did they promote previously which you could vote for, but are unable to now because of which specific policy? Can you give me an example of critical theory expressed by the left wing candidates in your elective district? And why these examples in particular make it so that you can’t vote for them?
That's an example of a badly thought-out hierarchy. The pseudo-directories should be something like "This PC/My Files/Documents".

The extended Apple+IBM Taligent demo I saw in early-1990s was impressive and also stylish.

It let you do things that seemed beyond the current convention with OO GUI toolkits and application frameworks. And there was also a bit of humor: I recall some demo of example application for some business approval workflow having something like an animation of a rubber stamp thumbs up, which was a real crowd-pleaser.

(This was around when a handful of Internet nerds and university students started trying Mosaic (maybe Netscape Navigator was also out?), but Web browsers at the time were mostly just a subset of LaTeX article.sty hypertext on a gray background, without even tables or frames, much less JS and CSS. So even those aware of the Web were still thinking non-Web-browser desktop applications, or writing a Web hypertext browser.)
That was true for runescape too, but it seemed like its ended entirely when you were able to sell membership bonds for in game gp on the grand exchange. Now its like, why go with a scammer website where they will scrape your info when you can give jagex $8 and have 60 mill in game in a few moments? Brilliant way to get around the issue imo and it practically acts like a stimulus package for the players so they don't have to run flax like I did for hours 15 years ago.
The Staples Center in L.A. Is being renamed the Crypto.com Arena or something like that, I'm not aware of any other crypto companies paying to have sports stadiums named after them though.
Crypto in general contains a lot less uncollateralized debt, surprising chains of counterparty risk, and so on than traditional finance. This is because those defi protocols and exchanges that want to survive have process margin calls and liquidations quickly or be wiped out. 3AC may leave some counterparties in bad situations, but those counterparties are totally insignificant compared to the entities one hears about in traditional finance.
Crypto companies put their names on stadiums. If they go bankrupt the names will have to change.
I'm no finance expert, but Tesla being down twice as much as Apple is not what I'd call a positive sign.

We'll see how Telsa's finances go once competition heats up. A major source of profit for them is selling emissions credits to other companies. Which a) undercuts Tesla's claims to eco-goodness, and b) will surely decline as others EV sales pick up. We'll also see how much that profit is affected by recalls and lawsuits.

In many cases, high customer satisfaction is indicative of a good future, but I'm not sure that's the case here. One, their satisfaction is in the same range as a lot of car companies, including BMW and Honda [1], so it's not a competitive advantage. And two, their current user base is a technophile, early-adopter niche. It's not clear that Tesla can cross Moore's Chasm and serve a mass audience that doesn't care who Musk is.

I look forward to seeing how it turns out. But given the way Musk is flaming out in his attempts to buy Twitter, his success is clearly not guaranteed. And that's before we account for him being distracted by trying to run 3 big companies at once.

There is absolutely no need for deserts to site solar farms, so the premise is nonsense.

Solar farms are wholly compatible with agriculture. Look up "agrivoltaics".
Not a crypto fan but regarding the 51%+ attack that is sort of covered by game theory. By performing the double spend they doom the network itself so it will either be forked so it may continue or entirely die out.

Either way the party carrying out the attack is unlikely to be able to benefit from it, especially if a prerequisite of the viability of the attack is the network already being incredibly week.
Ask HN: What are your go-to tools/books/blogs for cloud?
I'm looking for some practical, reusable cloud solutions. I'm a backend developer; however, sometimes, I have to create a new service using AWS services. Terraform is good in general.

My main problem is I sometimes miss a small detail which causes a production issue. It happened 2-3 times in the past few years.

Is there any good tool or practical book/blog to help me? I found a couple of Terraform generator solutions, but those are basic.
Most blog posts I've checked describe the high-level concepts and don't go into details.

Any suggestions? Thanks in advance.
Your analogies fall down in that they in no way relate to the tone of what's written there. Unless you mean the second response is analogous to screaming.
A startup named Crypto.com bought naming rights to the Staples Center in Los Angeles and renamed it to Crypto.com Arena. If Crypto.com goes out of business maybe the building will get renamed again.
Interesting. Was he the originator, or reacting to others?
What kind of washing or baiting is this called?
Technically you are right, but I think it would have to be a really widespread issue before the government tried to do anything about it.
Furthermore, there is strictly negative benefit to siting solar farms in deserts. It makes them run hot, thus less efficiently, and shortens their lifetime.

Siting solar on farmland increases farm yield and cuts water loss.

Note that the dot-com bubble lost about $1.7T [edited from B] in market cap, off a total of roughly $3T for the sector:

https://money.cnn.com/2000/11/09/technology/overview/

In the grand scheme of things crypto is still relatively small, another dot-com bubble or not even that. It's going to be a sideshow for the bloodbath that happens in the public equity and corporate debt markets (and eventually, the housing market), which is just getting started.
It makes sense that when a giant makes some movements or shifts it’s posture, that it can seriously damage or squash the little guys all around. Especially when that ecosystem of little guys is something the giant knowingly created around itself.

An example of suppression and silencing is: twitter! https://lidblog.com/twitter-censors-conservatives/. There are, of course, many other examples. Twitter silenced the hunter biden scandal at election time. The story turned out to be true and could have swung the election. Youtube has been restricting, shadowbanning and explicit banning conservatives for a long time as well:

Open lying is harder to prove. Who admits they openly lied? But we can at least show many, many, examples of leftist media being factually incorrect. Here's one: https://www.city-journal.org/exposing-the-washington-post-on....

It's always great when all the falsehoods are attributed to "anonymous sources".

A culture war is fought by winning hearts and minds, one by one, and also taking back influence, institutions, and power.

A non-leftist political opinion would be that the 2020 riots were worse for our country than January 6. an NFL coach recently got fined $100,000 and faced severe backlash for expressing this opinion: https://www.dailywire.com/news/nfl-coach-jack-del-rio-apolog....

Yes that's the entire point of contention here. Twitter is a company, its management can choose to treat it more like a town square or more like a closed network with stricter content mediation rules. Elon wants it to be more like a town square.

But to their culture, you're not a very good whatever to not be willing to sacrafice yourself for the betterment of the group.

Everything is a matter of perspective. You believe that the gods they believe(d) in are not real, but to them, it was. They were happy in their ways of life until the foreigners came in and forced their beliefs on them. Are/were they better off being forced to stop? No way to know. Soldiers in ancient times thought it was better to die in combat than escape to fight another day.
I liked his talks a lot, ended up using a rudimentary event sourcing system in my own hobby project.

It's not super big, but there are over 30 million events in there. It's all just running on mariaDB so no fancy software in there, there's this `stored_events` table and it just keeps on trucking. Software running fine :)

It's quite nice to keep history. I never made tables for actual payments, but I did store paypal events in this table.

Only recently did I realize this data is actually useful for me as support for my users so I made a UI loosely based on this query, and it just works

SELECT somestuff FROM stored_events WHERE event_type='paypalIPNSuccessfulEvent';

I made this event easily over 5 years ago, today the data is useful. Thank you event sourcing!

Edit: Oh and I shouldn't forget that in between this time I was constantly thinking about how big of an architectural mistake this was. I was just keeping a bunch of data, not using it, using some abstraction sold to me by some guy on YouTube...

Well, it has its advantages, but the biggest issues lied with how I thought the table had large performance issues. Turns out it doesn't really have performance issues, I just didn't know how to use indices :|

The aforementioned SELECT statement runs in milliseconds, where there are a couple thousand of that specific event out of 30m+

This article perfectly bookends my abandoned physics degree.

1. This reminds me a bit of the delayed-choice quantum eraser, which is one of the weirdest scientific outcomes and is the sort of thing that inspired me to pursue a physics degree. It implies a certain kind of time travel is possible, in the sense that in the present moment we can cause some past moments to collapse.

2. As my TA, Frank Wilczek successfully scared me off that physics degree by simply being so smart and having complicated things come so easily to him. Being confronted with the kind of horsepower needed to be successful in academic physics was eye-opening.
The reality is that transportation operations involve multiple events, each of which have a specific timing factor and variance.

There's arrival and departure (to the gate, platform, or quay) of the vehicle / vessel itself.

There's ticketing and check-in time, if those are required. Possibly security screening for air travel. And for aircraft, gate arrival time vs. wheels-down / wheels-up, where the latter includes taxi and takeoff queue time. Add to this the reliability or unreliability of actual travel times --- busses and shared-route transit must deal with traffic and delays, aircraft with weather and airport conjestion, ships with dock and pilot availability as well as weather factors, for example.

Schedules are written from several points of view --- the operator (when must vehicles be at specific points or departing from them), passengers, port or terminal operators, etc. Each has different needs. Learning how to interpret the published schedule to your own planning is key to effective use of such systems.
They're paying the penalty of crime. At least they're being given something productive to do, and easing the burden on taxpayers.

Just read about an Illinois father who drowned his three young children to keep his wife from taking them. You think it's slave labor for this man to work below minimum wage while being given a roof, bed, bathroom, and food, at the expense of our taxes?

I am surprised that rejection of an order could be grounds for instant dismissal in the UK. In Germany that would involve a lengthy process of legal letters to an employee. Something like 3 strikes. Also you can't just order anything from an employee. It's not the military, right?
Hopefully this time, we get some regulator action so we're never back here again. Each time the cycle gets bigger, the tendrils work their way into traditional finance - and more people get hurt. This time, the Quebec public servants are getting rekt on their investment into Celsius [1]. Now it's hurting pensioners, not just a bunch of degenerate gamblers and moonbois.

It's fine for a bunch of pokemon card traders to get rekt - but by the time you get to 3AC scale, it's time for regulators to put the kibosh on the whole space. They're securities. They either get registered or you go to Club Fed.

With all due respect, fingers crossed, this time it does not work out.

3AC is a hedge fund that actively traded shitcoins on centralized and decentralized exchanges and bought locked tokens from newish projects (like a VC).
A level of performance / ability where you can interview, get a job and the salary you deem indicative of your skill. This varies from person to person obviously.

For instance, for a while I had a CS degree and was solidly above average, but I didn't quite meet the bar because I sucked at leetcode and didn't have enough experience. So I accepted this, improved, and now have a higher paying job.
None of it has ever happened before during a recession. Crypto basically didn’t exist the last time the world had one. Being religious and so sure about the way something is going to turn out should be a warning sign to the self.
Tulip analogies are always apt & forever welcome. But looking at those ancient Dutch trading charts, there appears to be a single 99% crash, that occured in a single trading session I believe. BTCUSD has collapsed 70%+ at least 7 times.

It's global. There's always a new pool of money coming new.

And tulip bulbs are really only good for one thing. Extremely perishable, fungible, analog and centralized stores of value ;)

I have an issue with trying to make a profit off of a person who you decided to jail and who did not get to make upkeeping decisions.

If a person is paying for these services shouldn't they be a decision maker? The salaries of the guards, warden, the food, types of lighting/heat are all costs that the inmates should decide what level of funding they want to provide.
1. Look at the rate at which hedge funds hire people from ivy-league schools, compared to the rate at which other businesses hire from ivy-league schools. What explanations do we have for these different rates? (There’s a long discussion here which I’m omitting. There’s more than one explanation, but the basic hypothesis is that hedge funds value ivy-league credentials more than other industries, because ivy-league credentials are more valuable to hedge funds, and if they were just after skills, they would probably make different hiring decisions.)

2. Look at what happens when a hedge fund fails. What kind of business decisions are scrutinized (and which are not)? How are decisions justified? Are those justifications founded? (Another long discussion which I’m omitting. The basic theory is that you need to CYA for the inevitable failures. If you CYA and then the fund fails, investors may give you another shot. If you don’t CYA, you get replaced.)

I only save citations about a subject if I’m writing an article. If I were writing an article, I would post from my other account.
There were huge projects started to site solar farms in Africa, serving Europe.

They collapsed. The reason they collapsed was that there turns out to be less than zero value in siting solar farms in the desert, and solar panels have got so cheap that you do better posting more of them nearby instead of paying for the long cable.

The reason solar farms in the desert have negative value, vs. siting nearby, is that panels in the desert get hotter, so run less efficiently than over water or plant life, and last many fewer years. Furthermore, panels in farmland improve yield and water demand.
I think there's some % chance that this collapse will hit outside the crypto world. I'm not going to be shocked when we find out through some stupid chain pensions were invested and the like.

Could wind up with major governmental oversight moving forward, basically making damn sure it's barely ever adopted. Everyone always talks about "satoshi's vision" and what not, but crypto isn't going to be worth shit if you are forced to make trades in black market scenarios because it shit the bed so bad it took down serious stuff with it.

Granted this is probably worst case which i'd put at very low odds.
I think every cycle has dramatic stories. To me this is just another downturn where I buy with confidence and wait till the tides shift. I maybe wrong and that's fine. But history often rhymes.

Collison and Cowen are asking the right questions but are unserious about finding answers. We need better data, a journal, forecasting competitions, etc. Podcasts and twitter cliques aren't going to cut it. Orthodox economics isn't going to cut it. A Humanities-based approach isn't going to cut it.

Even more seriously, they've almost framed the inquiry as unanswerable from the start. What kind of answer or new discovery might they accept as an advance? What are the criteria for success?

"Through much, much trial and error and a lot of scientific article research, I've found the most consistent way to ..." etc..

Unless one has done proper, randomized, medical trials, I don't see how anyone could use such unambiguous language.

These n=1 experiences lacking in objectivity and also likely proper measures might help us discover new ground for things that might work (i.e. the basis for a trail), but without any testing it's not something any reasonable person should be walking around saying 'works', unless you mean to indicate you're referring to the literature.
