I got a PhD in a related field at an American university, and can give my 2c:

- It sounds like you're conflating getting a PhD with working in academia. There are _many_ jobs in the industry that prefer PhDs, especially in AI/learning. The PhD can be a credibility boot if you're looking at entering a field with many PhDs in industry.

- Many of the applications will ask for a personal statement as well as a research statement. My advice is to go ahead and write these statements and maybe things will become clearer. If you're still unsure, go ahead and submit the applications.

- If you're going to get a PhD, it is better to do it now rather than after a few years working (it's hard to go back to a small paycheck)

- Many schools offer a masters along the way to the PhD, and from what I've seen getting a masters helps a lot with industry work

- If your goal is to maximize lifetime earnings, work experience is more valuable than the extra 3-5 years of school (but the masters is probably still worth it)

Don't feel like you have to figure it all out before you graduate. I was unsure all the way until I secured funding for my research. At that point I decided to pursue the PhD because it was interesting and a once-in-a-lifetime opportunity. It's happened to be good for my career too, but I think it was worthwhile in itself.
I've seen a lot of articles like this one about big companies being dysfunctional on hiring and management recently. To the people that went through multiple companies like that, if you were 25 right now, where would you go, and why? Or more generally, what would you look for in a company, how do you evaluate them?

ROI heavily depends on the student. A college can be expensive and provide everything required for a good ROI (name brand, education opportunities, networking, internships) but still result in a low ROI if the student just expects to be handed a 6 figure job upon graduation while coasting and partying for 4 years.

It starts with who is let in the doors, and to some extent, it’s garbage in garbage out. Putting ROI solely on the institution is not right. Maybe you can say it should be the institution’s job to only bring in motivated students, but there are only so many of those to go around.

> Economics is the study of the statistical, game theoretic, and computational properties of a market.

I was taught in my Econ 1 textbooks that Economics is the study of scarcity. Game theory and stats didn't enter into it until much later.

Either way, it's just a semantics question about what "economics" means. The author has a real point about what's actually scarce here, and the contrast with people's expectations is a good one.
SLS pork is spread to all 50 states. Texas gets a good chunk of it. A small fraction of $2B is more than all of $10M.
I'm a CS professor and chair at a primarily undergraduate college. I've advised several students over the years who have gone on to be admitted to PhD programs at top-20 schools.

Here's what I would tell one of my students: If you're wondering whether you should do a PhD, the answer is no. At least not right away. Slouching into grad school without a strong commitment and a plan is a bad idea.

The most challenging parts of grad school aren't the academics. It's the long process, low pay, getting older, and uncertain outcomes that wear people down. If you aren't sure (yet) that you really want to do a graduate degree, you should try something else for a few years, then think about returning to grad school if you still have a desire to do research.

I worked for a few years between finishing my first degree and entering a PhD program. Those years were helpful in shedding the "undergraduate student" mentality and thinking of myself as a professional. Industry can also expose you to new problems and research areas that you never encountered in your undergrad program.

In terms of careers, you don't need a PhD for industry, outside of a small percentage of research positions. Academia is a different game and a PhD is required, but there are many different types of institutions that are looking for different things from their faculty. Teaching and advising students is the largest part of my job. We have publishing requirements for tenure, but the research culture isn't as grinding as it would be at a top-tier R1 department.
This would be true perhaps if this wasn’t SpaceX. They already moved the goalpost with Falcon

And I don’t think the author wrote what you said. His main point was that not one of NASA’s powerpoints even as much acknowledges that something like Starship might come round. The new constraints by Starship are a game changer.
If you had the skill to do some algebra and understand soem physics I could link some simple video that would prove that CO2 causes global warming , but I assume you don't believe the data in physics and math books either.
Perhaps Librem 5 can help you, which is a smartphone running desktop Linux. It even works with an external screen and keyboard if necessary.
I actually go against the grain here and say I like touchscreens.

Being able to draw on screenshots with my finger (I that a lot for work) is really nice.

At least it has the killer feature of having the ability to be completely ignored, unlike other "trendy" features on new laptops :)

Also, I can never find a good use case for the folding tablet modes.

Maybe it's because I'm not an artist, and don't my computer much for pure media consumption, but almost everything on the computer is designed around having a keyboard.

I find it silly to type on a software keyboard 5x slower than the keyboard already attached to the device.
Exactly. Thanks, I had forgotten where I had read that, this is a nice source.

Here's the TL'DR: The placebo effect is maybe not quite as powerful as it is sometimes made out to be. And the reason is spontaneous remission or reversion to the mean.

1. Initially, researchers tested a treatment, and when the patients got healthier, it was assumed that it was the treatment.

2. Then researchers got smarter, and tested a treatment against a placebo (control), ideally double blind and randomised etc., and when the control group got better, it was assumed to be the placebo effect, and when the treatment group got even better, the difference was the treatment effect.

3. Then researchers got even smarter, and tested a treatment against a placebo (control) and against no treatment at all, and when the no-treatment group got better, it was assumed to be reversion to the mean or spontaneous remission; when the control group got even better, that difference was the placebo effect; and when the treatment group got even better, that difference was the treatment effect.

Going from 1. to 2., it was realised that many treatments are not quite as potent as hoped, and that the placebo effect is quite strong. However, going from 2. to 3., it was realised that the placebo effect is not quite as potent either, and that there is considerable spontaneous remission or reversion to the mean.
Then clearly you need to read more. I suggest starting with "Power for All." Words matter. They create worlds. Narratives matter. They enable myths to persist.

Again. These are properties of human behavior.

Have you tried geometry nodes? It lets you use meshes from any object, allowing you to build up modifiers non linearly. I would say it covers 90% of the feature you're proposing.
The entire space reporting has the problem that simultaneously there is an established genre of fanboy fawning about space x, which is kinda unconnected to space x actually starting to disrupt space.

Right now, it looks like one could save a few billions if Artemis is not green lit a decade ago. However, private launches were still rare at that time, so in absence of a, likely expensive, time machine that's just not an option.

So looking at the planned timelines, Artemis I will circle the moon next year, and a crewed landing is planned for 2024, while star ship does not have a planned launch to orbit yet.

Also on a personal note, I am utterly astonished that there will be people on the moon before the subway station down the street is operational.
Great so nobody ever researches anything and we still all live in the stone age.

But at least we are pure in our hearts that we didn't mis-allocate resources when people were starving.

That this mindset exists blows my mind.

> Like, if you can't fix war at the level of horses, bayonets and canons, maybe not go for inventing aircrafts and tanks and machine guns just yet

Aside from the practical, problem of "Great way to get killed by people with guns that you don't have".

The underlying philosophy is equally flawed. Its like picking out of the technology bucket only things you don't like.

The same things that made those things possible also made a huge number of other things possible that would otherwise not have existed at all.
Not really, unless you're trying to build up a private fingerprint collection which can't be used for criminal cases anyway.
Is "takes one to know one" too childish for this?
Related: I've had this hunch for a while that the way we teach evolution in high-school biology is flawed because it still tends to implicitly be presented in progressivist terms. That is to say: as if things evolve towards something "better", and will eventually reach some kind of global optimum. And I think a part of that is that people aren't used to think in non-transitive properties, outside of Rock-Paper-Scissors and Pokemon perhaps. Maybe these dice could be used as an abstract demonstration of ecological niches being context-dependent.

> the flash controller is internal to the M1 SoC

Okay, it was part of the T2 chip before. And they were able to put replaceable SSDs into the Mac Pro. Those only contained the NAND chips and were proprietary, but still.

The problem I have with soldered SSDs is that flash memory has a limited lifespan in terms of writes. Once you're out of writes, then what? This is aggravated by the fact that M1 can't boot even from external media if the internal SSD isn't working.
Agreed, for some reason I thought we'd hit 1.5c by 2100 or something like that. It was very eye opening to see we're already at 1.1c

I'm confident that eventually we'll collectively respond but by that time the expense of the recovery will be huge and the devastation will already be here.

Don't assume that launches for refueling operations happen during the launch window. The window is really as long as you want it to be for refueling. Yes, there are engineering challenges associated with having fuel in orbit over a longer period.

I'll agree there is a shortage of plans and an excess of hope in what you're going to ship to Mars in the near term. But I can also see where others are saying -- something this big requires a slow organization like NASA to start planning now.
Latest post is more of a continuation of this one: https://caseyhandmer.wordpress.com/2021/03/04/sls-what-now/

I'm going to presume what author thought and quote him:

------

What does NASA do with teams that cost a few billion dollars a year to feed and whose main expertise is building rockets and space probes whose entire architectural philosophy is threatened by current launch costs, let alone the order of magnitude improvement that’s in the pipeline?

The Perseverance Mars rover cost $2.4 billion, which works out to a few thousand salaries for just under a decade. Thousands of people are needed to build this rover because landing stuff on Mars is so hard that subsystem masses must be tracked to a tenth of a gram, on a system that weighs a tonne. The whole thing is meticulously handcrafted from custom silicon, PCBs, titanium tubes, motors, cameras, and other awe-inspiring instruments. Starship will be able to land 100 of them per flight. Now what? How can NASA feed a team that makes one feather light rover per decade for a billion dollars if the demand just jumped by a factor of a thousand and the unit cost fell by the same amount? Set up a production line? Work out how to make them with a team of ten? Build one every two weeks?

In short, in a world where SLS’s ongoing failure is justified and/or ignored while Starship races towards transformational capabilities, NASA needs to think very deeply about its place in a human spaceflight program that appears poised to proceed without NASA at its center.

-----

So the point is it seems to be a question - what is NASA planning to do AT ALL in the world where Starship is flying?
This is a distressingly common technique for making studies say what you want them to say. I've dug into several dietary studies over the years claiming how this or that diet is good or bad for you, and a lot of them basically involve feeding the worst-possible $DIET_X to one set of mice and the best possible $DIET_Y to the other, and lo, $DIET_Y wins. So, for instance, you can feed a "low carb" diet that fills in the fats with a ton of transfats or with good fats, and you can feed a "high carb" diet that has a lot of whole grains or has a whole lot of bleached, refined flour, and produce whichever results you want. This is a non-trivial part of the reason why "peer reviewed" studies keep continuously putting out what seems like contradictory results.

Unfortunately, it means just "trusting a peer reviewed study" is even harder than it should be. You have to dig into the study to see if it even makes any sense which can be very difficult. And you have to follow the money, not "even" if the study says what you think it ought to say, but especially when it says what you want it to say.

Very disappointing when you go digging in.
You also didn't mention where to work. In my country a React job will get you 50k a year at most as a junior, and almost nobody recruits you if you don't have a master's degree.
> NASA is right to not put all of its eggs in the Starship basket.

The problem is that not only are they not putting any eggs into the Starship basket, they aren't even aware (or admitting) that the basket even exists.
Congrats to the team!

>Even worse, they only blocked people from Germany that didn't know how to use a VPN. German courts really don't get how the internet works.

I wouldn't make that assumption at all. As with many other examples, such as GDPR-related geofencing, a good faith attempt to restrict access usually goes a long way even if it's possible for a savvy user to get around the blocks.
If you are suggesting that there is a conspiracy to keep inexpensive drugs from being used to treat covid, then I would like to point out that corticosteroids - an inexpensive and widely available generic medication - are an accepted part of treatment for people hospitalized with covid, and has been for some time now. There is no conspiracy.
But isn't this just a question of how one truncates the expression for the sum?
You also see writers who clearly want to direct films or make video games but stick to writing because you can write a novel without fundraising and organizing a team first.
PSA: Widespread Remote Working Scam Underway
I'm building an application in this fashion at the moment in Go, and honestly, I think it's kinda painful. At some point I already merged the persistence with the domain model, so it's just the domain model with SQL related struct tags. I am tempted to merge it with the HTTP model as well, add JSON tags to it.

But everyone is telling me it's a bad idea, so I'm really not sure. A more convenient way to copy properties over would be nice.
Musk has promised that eventually they will use synthetic methane to launch Starship, so net emissions will be zero.

Awesome!
The author is a physicist, not an engineer and shows in all of his articles.

Physicists are trained to check whether a concept passes the constraints of the current theoretical models. If it does, the rest is just an engineering problem - i.e. take the theoretical upper limits of mechanics and material science and extrapolate from there.

No concern for the pesky 10% that take up 90% of the development time and make or break a product.

In this context: sure, there's equipment that can work in space. But all of this equipment needs to be operated and maintained by humans and there's where your problem starts.

Remote operation is impractical beyond the Earth-Moon system.
>That's not how monetary policy works but ok ...

Modern QE, for example, is not traditional monetary policy anyway, but ok. Nor is playing with such a huge percentage of the GDP, or facilitating lending to the already rich, to use to stock their fireplaces, VC bets, and in general, getting richer on a cheap supply of money...

>So you don't like some things the government does and therefore anything the government does is bad and we can have no argument about what spending is good and what is bad?

On the contrary, I like government. I just with it did things as a government of/for the people, as opposed as a lackey to oligarchs. You know, reigning on them, instead of high fiving them and being in their pockets. Or printing money to keep the bubble alive, so they can play with their phallic rockets.
LOL. Usually "diamond hands" isn't used for the kind of holders that lose everything.

But I really like those examples. Decreases the survivorship bias you have when this term is usually referred to.
Congratulations! This is the highest compliment that could be paid to you and your project, I'm quite jealous. In all likelihood, this Parrot language will go nowhere. That's not saying anything about Parrot, but a fact of life for most languages out there (including Gravity tbf, sorry). My suggestion is to not pay this a second thought and just keep working on your language. Every second you spend on this non-issue is a second you're not spending making Gravity language better.
The same principle applies how voting district borders are fought over in some countries.

You try to make the borders so for your party that you will lose by a big margin in one district while winning with a small margin in many other districts.
That’s a typo, it should be (3,5,7) every number should appear only once. My bad.
Again, what I'm telling you is that the government already has extraordinary power to take away your freedoms. Look into American incarceration rates for instance. The bad part of government power I'm supposed to be worried about is already here.

I guess putting ads in the security check area works? If I were the buyer, I would be wondering if people would associate my brand with the negative experience which is airport security.
It depends on whether it's advertising advertising, or just a sticker or maker's mark - you know, the ones these trays and other products in use at airports and security checkpoints already have.
Go first dice are cool but I don't think they are non-transitive. In particular they claim that each ordering is equally likely, and for any pair of players (Jack and Jill, say) we can observe that across all orderings we should find Jack preceding Jill exactly half the time. This would mean that no pair of dice should exhibit the kind of edge that exhibits non-transitivity in non-transitive dice.
I use Pi-Hole + Unbound forwarding to Cloudflare/Quad9 over TLS.

It would be nice if all servers supported DoT/DoH + DNSSEC and you could roll your own recursive DNS server and have more trust in traffic not being intercepted.

I don't know for sure that requests to Cloudflare or Quad9 are being surveilled.

Agreed. The argument seems to be I’ll be happy with Intel if IPC etc is competitive as I want the raw power and don’t care about battery life etc. Which might just be true for a very small section of the laptop buying market but leads to a much less useful product for the very large majority.
