I'd say the largest value add about Elon Musk is his ability to create a reality distortion field to convince large swathes of people to follow his dream.

I'm actually not being critical of Musk here. Jobs did this and you can see how transformative certain technologies have been as a result.

The Power of Simple CRUD
Ha! No, Microsoft--I was in the hardware supply chain group for a while, and The Goal was a common conversation topic there. I heard a few people call process bottlenecks "Herbies."
This is more obvious scenario.

Any invasion plans would require a ton of perpetration that would be seen months before.

The US Military is a logistic machine. No President would sit by and watch the preparations and do nothing. The death of a US carrier group in defense would ensure that the US would not backdown. Think of the US after Pearl Harbor. It would end with nukes and the US would “win” for some definition of the word win at that point. The Russians would op out hoping to come out the untouched as the US and a China destroy themselves. Because of this a well reasoned response risk wise would be for the US just to go nuclear day one and decapitate China before they saw it coming. That’s far more likely.
There are a raft of issues. The construction industry has not significantly benefited from large technological advancements that other industries have over the last century and is still human labor dependent. Wages have increased, we've decided it's not ok to kill people anymore, unions have removed exploitation in the immediate supply chains.

We also have more complicated, and are dependent on, soft and hard power structures to access and use capital. A great place to start looking into these issues is Bent Flyvbjerg at Said, Oxford

This makes sense. Our roads look like arteries. The universe is fractal. So it makes sense that there are arterial-like structures connecting galaxies.
Sorry! Thanks for moderating things.
Why, do you expect there is zero overlap between folks with an interest in science and those with an interest in spirituality?
Absolutely. Popularity is absolutely fallible.

But I don't take claims of "X language was better and should have won" claims very seriously, partly because it's claimed by advocates of so many different languages. Should ML have won, or should Pascal/Modula2/Oberon? I've seen that claim, here, just from different people and for different reasons.

But I also don't take such claims very seriously because, while popularity can be wrong, so can unpopularity. That one guy spouting off about how everyone else is wrong and he's right? Sometimes he is right - but not often. More often, that person who thinks they have the right answer is seeing less than the full picture. I mean, how many people use Java? Several million? Would ML really have been a better answer for the majority of those several million people?

I react the same in government, by the way. When someone says, "I know what you should want, and I'm going to make it happen, even if it isn't what you actually want", well, I trust the people to know what fits them better than someone who isn't in their shoes.
>If one hasn't studied at the university and read the real scientific papers and learned to compared the good ones to the bad ones in one's own field (and everywhere there are enough bad ones too) my impression one has no chance to be good at recognizing the difference.

True. Reading more papers seems to be more and more important.

>So it's really hard. The best bet is really learning to discover what the limits of he fields are, who are real experts in the field, then read what they write etc. It's never simple. But if you're just watching a TV where something is presented as a "debate" learn to recognize what's "behind" the two only people who are shown as two "sides": behind a real scientists could be the whole scientific community, effectively all the experts in their field, and behind the guy who "sounds" better in the show can be simply... money from some specific interest group which finances an "actor" who looks good.

I see. So basically try to look beyond the curtains even if it's a different field.

And thanks for the recommendations! Both War of Science and Merchants of Doubt look interesting!

>In short, there are definitely enough people who earn money by "selling" falsehoods. It was never an accident.

So people selling falsehoods is not limited to present era eh. I see!
Excluding certain securities doesn’t lower your expected return, it just raises the volatility very slightly because you are less diversified.
I think it's just a consequence of a free market/capitalism. Everyone is competing w/ everyone, so working as hard as possible, to beat the competition.

Remedies? Either cultural (it just becomes unthinkable to work beyond X, because that's taboo) or legal (limits on how much you're allowed to work).
Yep, not bad, but not in an epic sci-fi way like, say, Hyperion Cantos. It's funny and witty, kinda like a dramedy-political-thriller that just happens to be based in space.

I know another construct that has this structure: the brain.
I view large software packages like ERP systems as different from a tool. You're adopting the metaphors of the system. Sometimes those metaphors are flexible enough to accommodate some of the nuance of the origination you're in, but sometimes you strain them too much or more likely misunderstand what the system is really doing.

People who advocate for letting the ERP dictate the rules are using the phrase as a shorthand for, "If you want to customize the hell out of it you probably shouldn't use it".
Dragging out construction timelines drags out budgets. Developers (construction) got better at extracting value from clients and thus, time as well.
There is, but his description of the research process seems accurate at least for my partner (currently also in a structural biology lab for his PhD) whom I showed the blog to. In particular this depressing paragraph:

>Doing experiments is extremely tedious and usually trivial. Once you become familiar with some experiments, you do those experiments routinely and hardly learn anything new. Doing life science experiments requires extremely high concentration. If you made an error during experiment, say preparing a bottle of solution with incorrect concentration of some components, it could hardly be traced back. Your experiment results will thus be wrong and irreproducible. Some experiments cannot be fully automated by advanced instruments, and they require good hands to do fine operations. If you don’t have good hands, usually your experiment results would be inconsistent and untrustworthy. Experiments would usually take extremely long time to conduct. Unlike computer programs, they usually could not be “saved” in halfway. Many experiment materials and samples are fragile, sensitive to environments, such as temperature and light, and they have their “life cycles” as well. This means that the fresh experiment materials and samples should be used as soon as possible to ensure their quality. The same experiment material or sample is likely different to what it was two hours ago. If somehow you realize that anything went wrong in the experiments, usually you would have to start from scratch again, whereas for computer programs you could always start from somewhere in the middle as long as you saved it. This further means that your life will be managed by experiments and you will no longer have control over your own life. For example, once you started a scheduled 24-hour experiment, you would have to follow exactly to the experiment plan. If you scheduled to do something for the experiment, even if it was at 2:00 AM and there was storm outside, you would still need to show up in the lab and start to do experiment on time. Otherwise, the whole experiment might screw up, and you would need to restart the whole experiment on another day.

highlights a lot of the inefficiencies in doing lab research. The current setup of labs with PIs who own the resources and decide what experiments get done, seems to waste a lot of intellectual potential of grad students and postdocs. And also holding up this edifice is many, many undergrads and research technicians who exchange cheap labor for resume-building on their way to medical school and grad school applications.

Obviously there are advances happening in the field, but it clearly wasn't right for the author, or anyone who's not willing to play the game.
Given the publicly traded coal companies are cash flow positive they have little reason to tap the equity markets for capital. These are mature companies in the decline phase. For the most part they do not need incremental primary equity offerings. This isn’t like say, Tesla, which burns huge amounts of cash but has tons of things to invest in for future returns and is therefore heavily reliant on the demand for the shares. The coal companies are milking the cash flow in the decline phase for dividends and buybacks.

Therefore the decision/demand for the existing shares in the secondary market has little bearing on the company. So no - it doesn’t make a big difference.

Indeed, most are buying back shares in huge amounts.

The debt side of the equation makes a larger impact as the companies roll the debt and most lever the FCF to the equity. The aggregate demand for the bonds will have an impact on profitability... still not much of a difference.
Phase I is more “what is the highest dose that can be given safely?”
why are people so obsessed with dark mode?
My impression is that a lot of interesting "leads" are generated by ground based telescopes and only then examined in more detailed by space based telescopes. If you kill off the generating mechanism, then effectiveness of space telescopes could also decline a lot.
Speaking as someone who quit after medical school and codes professionally (going on 10 years), I'd suggest temperance on the recommendation. Debt is high but so is salary, if they are in it for the long haul they'll be just fine. If you think you want to be a physician, shadow some. If you like what they do, you might like being a physician. I met many doctors who I think would be happier not being a physician, but also many that I think wouldn't be happy doing anything else. I'm happy with my decision overall but frankly i couldn't imagine going back as an NP, PA, Dentist... or anything in the field that wasn't an MD. Those all have much better work life balance, but you need to realistically understand what it means to do each if you want to be happy, and select the one that feels right. (And if it doesn't feel right, Dentistry has the absolute best work life balance, pay, and ability to help people who legitimately need it).
It's not just the digging. It's the fit-out.

Channel Tunnel suffered significant delays and additional costs for instance because the brackets supporting cable and pipe runs needed to be taken down after everything had been installed because of a latent design defect and replaced.

Imagine how long it takes to pull 20+km of cable off the wall.

Also, compared to other construction sites, tunnels are a different beast, you often need to transport huge amounts of materials, people and equipment long distances to get to your work-front (and back again). It might be a straight line, but it's still far.

As much as I love the Channel Tunnel (my father was an engineer on it and I grew up during the construction) the actual outrun cost benefit ratio just isn't there. Extra ferries probably would have been more economical.
Where do they get new XP machines? I guess there are sellers out there with NOS machines but that has to be a heck of a racket.

For me the most valuable VM was one that ran Vista because it needed a certain compiler at a certain version that didn't run on anything else.

>Learning your first calling convention is like learning your first programming language. It seems complex and daunting at first, but it's really quite simple.

I will definitely read this as I'm also doing the Reverse Engineering for beginners, as well as getting sidetracked to learn Assembly with Programming From the Ground Up first.
Why motherfuckingwebsite.com is in my bookmarks
When I try to log into the wifi at Starbucks or the grocery store or whatever, usually it will send me to some internet portal to sign away all of my rights.

Usually the portal doesn't work correctly, which looks like 5 bars of wifi signal, and a privacy error when I try to visit any website.

I go to http://motherfuckingwebsite.com/ because it's delivered via http with no security cert, so I can get redirected to the shitty internet portal and continue using the free wifi.

This seems like a kind of sophisticated trick, and I can't imagine that the average soccer mom is doing that.

So what do most people do to get on the store wifi? Is there another trick that's better? Is the world full of people complaining that the wifi is broken when it's not? What do you guys do?

> The brick needs to be completely dried out to attain the maximum structural capacity (i.e., strength), but at the same time, drying stresses the bacteria and compromises its viability. To maintain structural function and ensure microbial survivability, the concept of optimum relative humidity and storage conditions is critical. Utilizing the humidity and temperature as physical switches, the researchers can control when the bacteria grow and when the material stays dormant to serve structural functions.

So it can't get wet.

> they use light from the sun to grow and proliferate with very little exogenous material needed for their growth

Do the bacteria just die after the initial nutrients run out?

Design System Checklist
I vaguely recall that the observable universe looks a lot like foam. And even more vaguely, that maybe this reflects inflationary expansion of random fluctuations in the early universe.

So maybe this apparent connectivity over implausible scales just reflects the fact that stuff used to be much closer together.

Edit: There's a great sequence on inflation in Takashi Miike's "God's Puzzle".

You can't have your PhD advisor at home, but consider how many people commute to jobs that could be done just as effectively from home/remotely. How many man-hours are lost to that.

Also, it seems like you're using public transport. You're lucky that that is a) a viable option and b) pleasant enough that you don't want to murder people after a few weeks of doing it. The majority of commuters around the world are using personal transport, which has a huge carbon cost and does not allow for doing other things while commuting.

Finally, there are plenty of studies demonstrating the link between longer commute and lower well-being and mental health. https://link.springer.com/article/10.1007/s11116-019-09983-9

Personally, I wouldn't mind a 40 minute train trip and a 5 minute walk either side, but a 40 minute drive is awful. I've gone from a 40 minute drive to a 10 minute drive, and I feel "free-er" because of it.

I've been using bash for nearly two decades, and I just found out that Bash is apparently the only shell whose built-in echo uses the -e option. I thought others used this too, but it seems every other shell's echo just implicitly interpolates escaped characters. POSIX actually says anything following '\' is undefined behavior. Apparently printf is the only portable way to interpolate escaped characters in output.

> As more and more people do it, it will decrease demand for equity in those companies and increase their cost of capital.

If I had to guess, Chevron, Exxon and Aramco doesn't have too many problems with cost of capital. All you're doing is making them cheaper for people like me who don't invest based on moral posturing.
How does that work? Is BlackRock starting new passive funds? The news stories I've seen don't say anything specific about what they're doing.
Your tone does come off as negative, especially the second question. I think virtually everyone agrees with that, so why bother asking unless you are questioning the intelligence of him (which I do not think you do, but you come off that way)?

Juul Scales Back Overseas Expansion
Nothing good comes out from playing videogames either, or archiving pictures of WWII guns, or ...

Collecting information (which is public by the way) is just yet another hobby, which can be used for good (training an ML algorithm), bad (annoying someone), or just be neutral (sitting in someone's archive). It does not mean that you use it to ruin someone's life.

Also, there is nothing wrong with stalking people, as long as you do not interact with them, let them know, or affect them in any way.
In a more convoluted scenario (cross sign) a server can really send you two (or more) chains so I'd take that "SHOULD" with a grain of salt.

For example, Let's Encrypt Authority X3 is signed by both ISRG Root X1 (their own root CA) and DST Root CA X3. The server could send you:

1. Server cert
2. Let's Encrypt Authority X3 (Signed by ISRG Root X1)
3. Let's Encrypt Authority X3 (Signed by DST Root CA X3)

Combined with:

4. ISRG Root X1
5. DST Root CA X3

If the client trusts 4, then it could form a path of 1-2-4. If it does not but trusts 5, then 1-3-5 would be viable.
But... the city is you! Without the trains that's more cars in your way when you drive your car.
