It is going to be highly radioactive at some point (when it's in use), so it does need shielding for that point.

It needs to be able to survive any kind of catastrophic detonation/break-up/crash landing you can think of, because the alternative is spreading a large amount of radioactive material directly into the atmosphere/onto the Earth's surface. For example, the Challenger orbiter itself was fine, but when the SRB blew up it took up the orbiter with it. So if there'd been any nuclear materials in the orbiter, even if they weren't used at launch, they still would've needed serious shielding.

And it doesn't matter if the consequences of said radioactive material release aren't actually that bad in the grand scheme of things (like Fukushima looks not to have been) -- what matters is that the public reaction to such an event would preclude the possibility of ever launching it again.

I 100% agree. *Note to anyone quitting caffeine for anxiety reasons, it takes about a month to notice the benefit.

Another pet theory I have is that a confounding variable in these studies is often the amount of work someone has to do, and the type of work.

Someone drinking 4+ cups of coffee likely has a reason to be that productive. Which may result in more intellectual stimulation, a higher income, and other differences that makes the two groups very different.

I'd like to see studies where the same individual both drank 4+ cups of coffee everyday for 6 months, and then quit caffeine entirely for 6 months and measure the changes in health, and output collectively but on an individual basis.
I've just tried on the YOAST generated sitemaps for Wordpress and.... it works.

But it just shows you a nested tree based on url depth using / as a delimiter - what it doesn't do is traverse the site or anything.

Still, it's quite pretty tho. I guess if you had a really deep url structure on your site, it would help you visualise it somewhat.

Nazism, which formed the ideological foundation of modern white supremacy, killed millions just a few generations ago. To argue that white supremacy doesn't have the potential to kill millions simply ignores not-to-distant history. We cannot ignore what has already happened many times before.
St. Paul in the late 90s, there was a series of underground (literally) parties, known as the "rave in a cave". They took place in the Wabasha caves: https://en.m.wikipedia.org/wiki/Wabasha_Street_Caves

The entrance to where the parties were being held has been sealed, but there are other various entrances near the river. Every few years some kids get stuck, and the city tries to restrict entrance. Caves are just too interesting.
> I don't get how the narrative has turned against SO

We win friends by being compassionate, empathetic, supportive, and nurturing; by applying gentle correction. Leading by example. Helping each other up. Leading from the front.

I was a manager of a high-performance team; made up of people that knew a lot more than I did, and I kept us together, working as a tightly-coupled unit, for decades. I have some prior art in carrots over sticks.

One of the big problems, these days, is that documentation is just awful. People think that "more is good." That's not true at all. It just means that the SNR is much lower, and we waste time, reading irrelevance. We are also under a lot of pressure to get results fast. No time to look stuff up. Start coding.

Finding answers, in an efficient manner, is a real pain.

SO is a marvelous idea, and I totally support it. Ironically, I suspect that the "gamification" that has made it so successful, is also contributing to the issues it is facing. I do not have the answer. I think removing the gamification would also destroy the utility of the site.

I like the idea of the SO Story. Here's mine: https://stackoverflow.com/story/chrismarshall

I love SO. It is a big "go to" for me, and I have also asked twice as many questions than I have provided answers. I think that I ask very good questions. Sometimes, I'm wrong, and I don't mind finding that out. I become right by being wrong, and learning differently.

But people seem to be terrified to ask questions. I have no idea why. I am constantly asking questions; even "stupid" ones.

Reading some of the meta conversations, and seeing so many high-score members with single-digit question counts, says a lot. Whenever there is an election, my principal coefficient is the candidates' question count. I don't want to vote for people that think asking questions is something to be ashamed of.

I have over 35 years of shipping software. I have a great deal of knowledge and experience; far more than many folks on SO, but I also am constantly trying out new stuff that I don't know how to do. That makes me a n00b, all the time (I write about that, here: https://medium.com/chrismarshallny/thats-not-what-ships-are-...). I don't always know the best places to look for answers, and appreciate RTFM responses.

What I don't appreciate, is some person telling me that the fact I didn't watch some well-known (to them) video, or read some well-known (to them) article, makes me a "lesser person," or (an SO fave), "lazy" (anyone that actually knows me, knows that "lazy" is not a word that can be applied to me). I appreciate being directed to the video or article, but the nasty sauce is not a condiment that I prefer.

UPDATE: I removed some stuff from this response that was probably not necessary to the conversation, and would not be constructive. I hope someone was taking notes. That's how we do it.

Why do we only serve user interfaces over the web via HTML/JS interpreter inside the browser? If you can somehow provide some isolation (something docker like) and not yet thinking about delta changes, why would we not able to load e.g. a native QT application over the network (i.e. using DNS but instead of serving HTML over the webserver, serve a native application)?

Hi, this is great. A few bits of feedback - let people skip lessons (those variable declarations are very tedious if you know what you're doing).
It would also be good to automatically highlight the value field after creating a new frame variable. It takes about 4 keyboard actions to enter the value which is a bit frustrating. I get the forced restart is helpful for newbies to learn but I also found it a bit frustrating coupled with the interface.

I don't see where you're getting "extreme-left white anti-capitalist" from the police description "white racially motivated violent extremists."

'round these parts at least, what they're describing is our local rural and suburban militia-types trying to false-flag violence to kick off what they perceive as an inevitable race war. By their own admission, the people who get caught burning cop cars and such are about as far away from left-wing as you can get.

Yes there is. Server platforms are connected to more storage, higher bandwidth networking and more exotic sockets (more than one CPU). It is one thing to support lots of PCI express lots on paper. It is another thing to have a working solution that doens't suffer degraded performance when all the PCI express slots are in use at the same time.

None of this is rocket science but it takes money and engineers time to make these things happen. Intel has more of both at the moment.
It may not be something we know yet -- based on reading the available materials it doesn't seem like we got past the stage of designing the engine on its own.
But the study itself is a model, so it's theory rather than practice.

I had hoped that the article would be about real world results, but it's really about comparing different results theoretically. Which is also helpful, but not nearly so helpful as data.

Actually gathering data is hard. The effects of sugar in the diet take decades to show up, and there are millions of variables and compounding factors. So it's not really a surprise that the article is theoretical rather than practical, but it is disappointing that the headline doesn't make that more prominent.

The real-world experiments will be policy, and those policies will have to be driven by these models ahead of there being experimental results. So we have to do it. But we won't know how good they were for a long time.
> Caffeine is 33 times more soluble in hot water!

On the other hand, you "boil" your coffee for 2 minutes, not 2880 minutes (48h). But I'm no chemist, so you might still be right, despite the different orders of magnitude.
Also, we're not factoring in the water/steam pressure.

Anybody volunteers for extracting coffee with an espresso machine for 48h?

> Hardly anyone is doing that. But, evidently, a lot of gamers want that.

Not enough really, we've had the Deus Ex reboot (Human revolution), Dishonored, Prey and their respective sequels, they're all great games but they didn't do amazingly, they mostly did "ok", they're all now on hiatus with their studios working on other franchises.

I think these games (immersive sims) are actually pretty difficult to make and the reward just isn't there vs other genres out there right now.
And sadly that attitude is why you got the Bunga Bunga Parties scandal that VW and IG Metal Where involved in.
Transporting fissile material with chemical rockets is dangerous, it's making a dirty bomb and hoping it explodes in one direction. That hasn't always worked for transporting people.

If we say there's no life on the Moon, we still plan to be there. The fallout could affect the use of the Moon, which is far more important.

If you have stomach or acid reflux issues due to coffee but want to still feel the effects, you should absolutely look into low acid brewing techniques, you'll find that cold brew / toddy style brewing is much less harsh on your stomach and can be purchased at most coffee shops, at a grocery, or created at home with a super simple glass jar and a simple paper or cloth filter and time.

Toddy / cold brew is not the same as iced coffee (iced coffee does not have the low-acid properties that toddy / cold brew does. There are also different types of beans and a dark roast is lower acidity.

Finally, if that still doesn't work, switch to matcha. You can get culinary grade from ippodo rather than the finest grade and it's the same quality.

I try to view these things differently: we shouldn't tax sugar, fat, alcohol, tobacco, etc., because they are sins that we try to reduce the use of for moral reasons. We should tax them to help mitigate the extra burden the consumers of these products put on the public healthcare system statistically speaking. I speak of course from the perspective of a country with good public healthcare, i.e. most of the developed world.

Ages 0-22: zero times, basically never sick, never had strep or a sinus infection even once. Maybe, maybe had very mild cases of the flu once or twice when very young but then never got it again in that age range, despite never bothering with the vaccine or taking any precautions whatsoever. I'd get my "annual sniffles" when I felt slightly off and had a slightly runny nose for about 36 hours. That's as sick as I got.

After that, once a year in a good year, twice in a bad one, and I get the flu every other year or so, even with the vaccine. If I get the flu it also gives me a sinus infection more often than not. Nose slightly stuffy 100% of the time, now. Almost all my strep and sinus infections trend toward landing me in the ER, on saline, if I don't get antibiotics—rarely do they just go away. Haven't made it quite that far yet but I've been damn close.

All I can figure is HGH is a hell of a drug. I was also super-fit (looking, plus solidly healthy-range BP) until about the end of that age range, despite eating ~2x my on-paper "maintenance" calories of pure garbage food every day. Go figure. I eat much less and much better now, am fatter, and get sick sometimes rather than never getting sick. Getting old sucks.
Open IP over VHF/UHF
Advancing HTML is indeed something that the w3c members aren't super interested in. There are a few reasons for this:

1) Changes to HTML can create security issues, especially if it results in a change to the HTML parser. You have to consider that non-browser use cases still need to be able to parse HTML correctly. Since we opted to make HTML versionless with <!doctype html> it became harder to do.

2) Big changes are harder to get consensus on. This is one of the reasons why they opt to do smaller, less controversial changes.

3) w3c and whatwg are dominated by large corporations, who hire thousands of engineers to work on their web properties. They are able to overcome the shortcomings of HTML easier than small teams and single-developer websites.

I agree though, this is a major problem. HTML is essentially a dead language, no major changes have been made in almost a decade.

That's not an objective value. If it's relatively simple to tax and direct funds from 'A' to treatments...like cigarettes. We can (and do) tax lots of sources of cancer, but convenience is relevant to forming public policy.
There's no margin in micropayments in general due to transaction costs.

Nuclear-thermal rockets still require a "fuel tank". They heat up a reaction mass (typically LH2) and then throw it out the back. So they can't burn continuously, they'd run out of reaction mass.

You're thinking of nuclear-electric, which uses an ion engine just like solar does. It can burn continuously, but it has incredibly low thrust.

edit: (Note that I'm basically saying the same thing as baq, just in a different way)

edit 2: except for the part where I'm wrong.
Delayed gratification means that you are willing to work on tasks that are not immediately fun or are frustrating or when manager is not looking. It means that you are more likely to keep doing tasks whose benefit is in the future (like writing tests). It means that you dont need pat on the back and managerial supervision so often to keep motivating.

Lack of healthy respect for authority typically means more fights about who will do which task and more likely to unilaterally refuse to follow random parts of code standards. It may mean refusal to close jira tasks or open them. It may mean that analysts have much harder time to convince that one person to do what is needed, again.

Software development is typically strongly team work and requires quite a lot of coordination among people with opinions. When one person decides he does not accept authority of analyst, architect or manager, yes there are consequences for whole team.
Yep!

I can’t drink much coffee. Maybe it’s the acids? I don’t know. I find it’s super harsh on my stomach.

I usually just munch whole cocoa beans these days, or drink cocoa powder in hot water with milk and a small amount of sugar. Way more food-like as it’s very high in protein and fats, high in magnesium and anthocyanins, so results in an overall smoother stimulant effect and is way more nutritious.
A Pre-WWDC Post: Put the Moon in Orbit with Reality Composer
I agree that when they make a mistake in the form of applying the rules inequitably, get called out, and fix it, that's a mistake.

But I claim that when they make a mistake in the form of applying the rules inequitably, get called out, and double down on applying the rules inequitably, that is not a mistake, that is capricious.

There may only be a small number of times they have been capricious, but they are not "making a mistake." They are applying the rules capriciously.

And while nobody is getting killed, the principle of justice is the same here as in our society. Injustice anywhere is a threat to justice everywhere.

One person imprisoned for a crime they didn't commit and the police knew they didn't commit taints the entire justice system. It removes confidence for everyone.

It's the same principle here. Mistakes, fine. But applying the rules inequitably and doubling down on that even once taints the system for everyone.

TL;DR I agree that the system usually works. But for a mistake to be a mistake, Apple has to be prepared to fix the mistake, not double down on continuing to have different rules for different developers.

Like many things in life, this isn't a black and white issue. Higher education isn't for everyone, some people benefit greatly, for others it is a waste of time and money. It shouldn't be a requirement for moving up in life but one of the options. There should be different paths for acquiring the skills required to advance in life. For some it should be university level higher education programs, for others it should be vocational schools and apprenticeships, etc.
very very fair.

mDNS is just the method of communicating what traffic should be sent where. The "switchboard" listens for mDNS broadcasts that tell it what services want traffic routed to them under what conditions. A "node" (which was a bad choice of words) is the other side of that, a program broadcasting one of those mDNS resources (e.g. send traffic that's been sent to the domain "example.test" to this machine on port 8080)

Worth noting that Fugaku has no GPU/accelerator; all the compute is located in-core (cpu). The core itself has some GPU-like qualities, of course, since it's more optimized for semi-uniform compute throughput than a "normal" CPU is.
I really like the German higher education system. Unfortunately, the USA conflates universities and applied universities.

Most people who go to university in the USA, go to what would be closer to a Fachhochschule. Smaller colleges and universities that don't grant PhDs and whose professors have research output is closer to "write a paper in the summer" than "run a research lab".

Most people who have negative views toward their university experience in the USA, I think, feel that way because they thought they were going to a
Fachhochschule but actually went to a university (or vice versa).

I don't quite understand how the USA can look at our education system, look around the world, and then conclude that technology will be our salvation. No. Just build a system that works like the perfectly functional and affordable systems in much of Europe.
Denoising Diffusion Probabilistic Models
Sometimes being too cautious can cause harm too. It's not so clear cut as you might think. For instance, pushing mammograms earlier in life causes over diagnosis (around 20% in one study), leading to invasive surgeries that were not actually required, and they're not without risk. It can be pretty intense having a cancer scare, too.

So if we spend more money on these and we do them more often yet they don't actually improve mortality, is it worth it? There's a trade up there which your doctor should be making.
If you enjoyed Masters of Doom, I highly suggest Blood, Sweat, and Pixels. Not as laser-focused on a single studio, but great reporting on the industry, both positives and negatives.
That makes sense - thank you for your reply!
Is this an argument against my concern? I can't tell. I think poor education is a major issue in our (world) society and makes people more vulnerable to things like disinformation which is rampant today.
