None of issues you listed matter at all if launching stuff to space is cost prohibitive.

Without cheap space access they are not even worth properly researching.

> One where all of the waste we produce can be reused to create new drinkable water, air and food, and to reliably continue to do so between Mars launch windows.

None of that is as big of an issue if you can launch often and a lot of stuff. In the limit you don't need to recycle anything and everything has multiple spares. You can also launch outside direct constraints of Hohmann transfer orbit. Again, payload limitations and time are the main reasons we use Hohmann transfer orbits.

> The second biggest is probably avoiding contamination of Mars, if we actually care about exploring one of the biggest mysteries of life - has it arisen only on Earth? Are there other modes of life possible, and what do they look like?

We will not avoid contamination. It's impossible to do. Where humans go our microbiome will follow.

I personally think we should intentionally seed all celestial bodies with life as soon as possible anyway.

If we find life in our solar system (especially life independent from Earth) we should become a lot more aggressive with space settlement, because it would make "great filter" ahead of us hypothesis a lot more likely. Settlement outside solar system should become one of humanity priorities as a matter of survival.

Going to Mars can be a suicide mission and you will still find people who will be willing to go.

Not a showstopper for the willing.

Maybe the commenter was just sarcastic? My 10yo daughter always tells me: when you like something, you remark it so much, dad. I just think it is important to celebrate other people accomplishments: it has good effects on the world.
There are still some cases where you will need to eject (if you want to embed as a view in an unmanaged app for example).
If you don't mind ~3m resolution you could pay Planet labs for a roughly once a day (weather dependent) Google Earth.

However, large parts of google earth uses aerial (i.e. non satellite) imagery.

So yeah, way of.

Also, if you do a quick back of the napkin math, it's a lotta data.
It depends on what you are trying to do. If you goal is to host some hello world apps, you shouldn't even think about it. But if you are going to build micro services that scale, k8s should be one of the choices. Anywhere in between? There are most likely better options.
I've seen my comments come back from -4, and being flagged. Apparently, 'unflag' action cancels one 'flag' action. Thus, local oblivion is not irrecoverable.
Great points! I am still trying to figure out how to best use functional programming with JavaScript. I've found writing performance critical parts imperatively while being conscious about shared mutable state is a decent compromise.

> My second advice is to not use recursion to process arrays languages (like JavaScript) that have a very limited call stack size.

Can also confirm this, here was my process on the some of the harder days in Advent of Code:

1. I wonder if I can solve this in a pure functional style with JavaScript

2. Yay, it works on the example input

3. Oh, I hit the call stack limit on the real input

4. Time to rewrite the recursion as a loop lol
Not dying just because we can't, yet, would be pretty important.
And suddenly you care a lot about the "how", not just the "what". Voiding the whole "but it's declarative!" argument.

At least in imperative code the "how" is explicit. In functional code it's implicit and you need intimate knowledge about compiler and/or runtime to know what's going to happen.
The Uranus Experiment (1999)
Yep! If the methods create new objects, and leave the method arguments unchanged, you'll likely be writing code that's vaguely functional.
Sure. My point is simply people can be referring to lacto-fermented cucumbers without realising it. The vinegar is often added for shelf stabilisation of fermented cukes is my understanding.
Ego and hubris matter as much in physics as anything else.

The contention here I think is missing the possibility of a breakthrough or two.

We are making 'step functions' now and again in a lot of things, it's not entirely infeasible that a couple of step functions makes space just a lot easier. Maybe in superconducting or power generation or wireless energy transfer. Maybe if energy is super cheap and light, we really can haul a couple of orders of magnitudes more mass up into space, the 'close system' of keeping humans alive equation shifts enough to where it becomes much more feasible.
> rotating section to simulate gravity.

thats an interesting one. Humans can only just about tolerate rotation rates of about 1 rev/min or slower or get dizzy. That means the radius of such a rotating habitat has to be quite large to achieve any meaningful acceleration, which leads to its own challenges.

For example, to achieve 0.5g at rotation rate of 1/60 per second requires an arm length of 0.5 x 9.81 x 60^2 or about 10 miles. If you tentuple the rotation speed, ie 10 revs / min, you still need a radius of 180m
Investment Banks, Management Consulting, Big Law, not so much either...granted, a Harvard grad with 3.5 will get more slack than a kid from Random State School with similar grades and major.

But still, many of the companies mentioned above still just look at the GPA - not so much at the actual content. Career coaches for places like that will advise college students to focus on maximizing grades, at the cost of intellectually demanding classes (or anything, really!) because in the end - recruiters don't care whether you took Introduction to Theater, or Math 55 at Harvard.

So yes, at least big tech - even though the technical interviews can be tough - are indeed making the opportunities more accessible. You're not getting blanket rejections based on your freshman grades.
Not liking the result because of a conflict of interest is still not liking it.
Human civilization is only 5000 years old; Homo Sapiens is 300,000 years old. We have 5,000,000,000 years to plan for this eventuality.
I think the most interesting thing about C++ in 2022 is that big C++ names at Google are saying in public that if you can use Rust instead of C++, you should.
https://github.com/carbon-language/carbon-lang/blob/trunk/do...
Its a bit disappointing that the C++ community and stakeholders haven't found a way to address perceived shortcomings and (why not) reinvigorate and generate excitement about the ecosystem. The fact that people choose to embark on enormous investments to build alternatives from scratch (e.g Rust) might suggest that the cost calculus between maintaining compatibility with legacy code and future-proofing the language has now shifted decidedly against the former. C++ does not feel like the kind of beast that is destined to become the new COBOL. Its continuing popularity in game development is just one of the areas that could see enormous growth and evolution.
Remove the word ‘environmental’ and your statement gets better.
Just another request to stop citing Tiobe. This index is misleading and harmful.

52 with at least a million native speakers according to https://en.wikipedia.org/wiki/Languages_of_Europe . Of course, limiting it by number of speakers will exclude languages with strong political or cultural presence, just to mention a few, Maltese, Icelandic or Welsh.
Is that meant not really small talk-80 control the hardware, up, interrupt? Barebones?
Fair enough. This may be where there is nothing more to say. But just in case - why is it necessary to centralise the decision for making risk-to-benefit ratio assessments? Everyone has different risk profiles and may have reasonable disagreements about how dangerous the risks are vs the benefits. We've learned that several widely used vaccines were more damaging than the health authorities realised, but nearly nobody has a problem with them having been rolled out to the masses. This suggests the standards of the health authorities are unreasonably high. When they lowered their standards for COVID there was barely any extra damage done, we're measuring the incidents in single digit cases per million.

A lot of people - dare I say most - have a higher tolerance for risk than the health authorities do. Why is it necessary to hold back progress because of nervous bureaucrats? We could make faster progress by letting people willing to take risks take risks.
Ah yeah, probably. Misread it. I didn’t sleep that well. :)
It has something to do with genetics. Maybe you understand, once you have children?
MacBook Pro 16” with Screens.

Almost always with 2x 27” 4K Displays.

Nothing fancy, just the Dell range and whatever I can get a good price on.

I’d prefer 24” but you can’t get them at a sensible price. I’d use Apple displays but they are out of my budget range!

I tried 32” 4K displays, but they are too big for me!

Almost never gets used as a laptop. It just moves from desk to desk.

I get the 16” as when I do need to work directly on the MacBook, I want as much space as I can get!
“It turns out there’s a reason behind our cravings. Cheese contains casein. It also contains casein fragments called casomorphins, a casein-derived morphine-like compound. Basically, dairy protein has opiate molecules built in. When consumed, these fragments attach to the same brain receptors that heroin and other narcotics attach to.”
I think the original statement doesn't really get to the truth of it. High density and vibrant communities are positives for property value. People objecting to these changes either aren't thinking logically or they aren't objecting to the value part. They want to preserve the character of the area they moved in to.
> In finance or medicine, it's often illegal[0] to delete customer information before the end of an expiration period (minimum several years).

There are also laws that require you to delete customer information. For instance patient data in situations where consent is withdrawn. So either way you can’t rely on “it’s often”. And on the flip side of things the legal requirements you are referring to are typically the audit requirements, which are still better served using audit tables, since it’s not enough to have a “current data” and “data that is currently not active”, since you need logs of who changed the data when, and you can easily run into situations where something is soft deleted, then restored, then soft deleted again.
Your individual->team->organization breakdown is an excellent way to look at it. Simple, short, perfect. Thanks.
Pre-allocating the size of the array lowers that number even more.

Persistent data structure are really useful, and are (often) magnitudes more efficient than DIY-immutable data structures.

Imperative ones however, like you mentioned, are often (comparatively) near ideal by virtue of being imperative.
Yeah that's definitely an understandable feeling. But on the other hand, if representation matters (as others in this thread claim), it seems hard to please everyone? Supposing you had a group that's 100% white by accident, and they know representation matters. Because they're 100% white, they're starting from a disadvantage: If you want representation, it helps to have representation already! So from this perspective, being 10% nicer to non-whites who join the group seems like a natural solution, to overcome the chicken-and-egg problem.

Maybe the right compromise is to just be especially careful not to be rude to people who are underrepresented in the group, and not worry about it beyond that?
I hope you'll recover during the day! Take it easy :)
Maybe the sport is sending them there? It was tried with Australia, so maybe Mars is the new frontier?

Assume humans are the VN machine. We can make space suits and greenhouses etc., so it's not crazy.

Assume reproduction such that population doubles every 25 years. Fast, but not insane.

(1000/25) = 40 doubling periods

8e9 * 2^40 * 100kg = 2.7 Mercury masses, or 12 lunar masses, or 1.3 Mars masses

That's a worst-case bound using a biological anchor. Dedicated VN machines can plausibly be faster: even if it's something weird like staying with biology and uplifting dogs, that's now 75 years, a plausible but currently hypothetical self-replicating 3D printer could make the timescales even shorter.

The sun provides enough power to do it in a week or two, though anything less than decades may have thermodynamics issues.
Sounds like there was a bit of misunderstanding on my part. Apologies if I came off antagonistic, it’s been a hell of year.
> that doesn't mean fiction cannot contain facts

I never said "cannot contain facts". You're arguing with your strawman.

> I don't think anyone is saying you should cite fiction alone

Just about everyone arguing with me is trying to justify citing "The Jungle" as valid source all by itself. It's a work of fiction.

How about we just continue to have robots colonize Mars? Just get increasingly sophisticated machines down there to build up the infrastructure. Maybe in 200 years they might have built some nice domes and have earth like gravity/atmosphere inside that animals and plants can be brought to Mars. And maybe then some humans might see it as an attractive destination.

In the mean time, we can colonize difficult places like under the ocean, the Sahara desert, Antarctica, maybe even the moon.
Another important piece of the puzzle here is that politicians commonly update their positions in response to polls. (E.g. "politician X saw a drop in their polls after they said Y") So if polls become unreliable, that is potentially a big loss.

Here in EU the solution we have is to simply have formal rules that a university can only give 10% As, 25% Bs, etcetera.

This isn't enforced per class, but should prevent grade inflation. It might get weird in competition with people from US schools though, when someone with straight As is found to be a C+ student.
There's a noticeable difference in my abilities at the start and end of the day.

At the start I have more processing power and short term memory grunt. At the end I have far more knowledge loaded into cache.

The next level of coordination is scheduling your time to take advantage of the morning horsepower, and end of day creativity.
> Why did I get to talk to the admissions officers? I played sports. Even D3 schools had a former admissions officer or dedicated one who gave the coaches reads on everyone pre-admission. I got these reads from them.

How come sports have such important role in the US school system? Between this and all the scholarships I hear or read about, I feel that sports are effectively a "cheat code" for academic success - why learn anything when you can play all day and still get into the best universities because of athletic accomplishments?
Ugh that's terrible. The College I went to the professors seemed to have the attitude of this program is hard and our students need all the help we can give them. I think half the students dropped out.

Grade inflation always seems weird to me since they stamped it out in my program 40 years ago by enforcing grading on a curve and not allowing students to drop out and retake classes after the first two days. Grading on a curve was real. I once got a B with a score of 13/50.
Of course driver breaks are important but when automated driving is here it'll be just a nuisance.

Over time, the competition to get into these schools have gotten tougher and competition is now on a global scale for schools such as Harvard. If you don't grade on a curve, would it not be normal to see students do better? There are more past exam papers, more prep before you even join the school and more onus on the students to do well because they attend such a great school.

I think its fairly obvious they've hit some problems. I know they lost a lot of key people in their silicon development team so perhaps thats the reason.

Whatever it is they're struggling to get the performance they need for a Mac Pro level machine.

I'd imagine part of it is going to be that they'll want to continue using Nvidia or AMD GPU's to allow for higher performance. That can't be an easy or simple thing to get working with their custom ARM based architecture.
Being self sufficient isn’t nearly enough on it’s own to ensure survival.

I don't know if I got in me to write out a ton here--I probably owe this sort of thing a blog post or write up at some point--but I'll just say that marketing _really_ likes terms like "unlimited", sales loves to sell committed and contractual spend, and engineers love to automate (particularly in a PLG motion).

So you get things like...a lot of compute or bandwidth spend. (You know, I tried to think of other examples, but at some point it really does come back to the compute and bandwidth.)

And in a up-or-out kind of growth mentality, it's easy to handwave a lot of that away as just growth spending. But if the returns don't kick in big time at the end, you've just accelerated your runway.
Getting to the moon or mars is trivial compared to stable self sufficiency.
You are wrong by 3 digits.
The “Ones and Tooze” podcast covered this well in their most recent (12/30) podcast.

Basically, this is to be expected. Home owners looking to sell put off their sell when conditions turn sour. The construction industry is historically fast reacting and bipolar. The good times feel slowed by bottlenecks (their word) and the bad times like abyss.

Importantly, the mortgage backed securities which made 2008 so bad have largely been sidelined. That at least won’t be the thing that turns this downturn into a repeat of 2008.
This is on the "cheap" model 3 version, right ?

No problem. They will fix it with an OTA update. /s
XServe would probably be pretty popular with the recent shift to ARM based servers for their lower power consumption. The problem would be their insistance for them to run full blown macOS instead of a dedicated Linux based server OS.
Generally yes. I've been interviewing people in tech for about half a decade, and it never occurred to me to ask about their grades. It is irrelevant compared to testing how well the applicants know what they need to know for work.

Besides, partially thanks to grade inflation and partially due to arbitrary syllabi, universities grade students very unreliably. I can imagine a scenario where a recruiter or an interviewer would bother to work out what grades mean in one or two local universities if they recruit most of their employees from there. But in large tech companies that recruit regionally or globally, there is simply no way I, as an interviewer, will spend the time investigating how some professor in a college or university I have never heard about tends to grade their students and on what subject matter. Just think about how ridiculous that sounds.

The universities do not prepare people for work in tech anyways. There are tremendous practical knowledge gaps fresh graduates have compared to anyone who has been in tech for barely a year. A dropout candidate genuinely interested in the practicalities of work in their tech segment will easily outperform a 4.0 GPA BSc graduate who fails to engage with the subject matter.

More and more candidates are skipping BSc degrees and instead spending time building their portfolios targeting specific companies (using the appropriate frameworks, programming languages, and tools). They tend to be good hires and often want to prove themselves more than university grads. This works out for the team (the employee shows more engagement with work and more effort) and the employee (higher work satisfaction).

I am not saying that a university degree or your GPA is meaningless. I am sure some companies care about the latter, and many still care about the former. But compared to actual know-how, just undergrad degrees and 4.0 GPAs do not stand a chance.
>Apple was the only company shipping them [that I could find] at the time.

Last I checked, they still are. What other company makes a 3m TB4 cable?
Yeah, but that's kind of how human progress works. For each Edison or SpaceX which successfuly commercialised a technology, there are Nicola Teslas and Apollo programs which did it way before both the tech and the society were ready for it, in a one-shot way that's a bit difficult to replicate.
mankind is heading for space ~ this is unstoppable. colonising mars makes a lot of sense as its the only other semi habitable planet in the solar system. short term ~ there might be some interesting mineable ores on mars. medium term ~ lower gravity makes it easier to launch ships into space / build a space elevator. long term terraformation of mars is a possibility.
