I personally know people that work at SpaceX (because my wife works there). Reusable rockets weren't a cheap marketing ploy. I don't have personal contact with anyone at the Boring Company, but it's located right across the street from SpaceX in Hawthorne, and I know that many of the people there are from SpaceX. In fact, I just drove past the test tunnel there this morning, as I dropped her off at work.

I might be biased given where my friends work, but how do you know that calling it a "marketing ploy" isn't an overly-cynical view of things? After all, Musk sees more cost reductions coming, and his track record has been pretty good (if a bit late at times).

I also have some questions for you that I hope can resolve things:

1. Do you believe it is possible to do better than the infrastructure projects in other countries that you cite?

2. Do you agree that it would be a good thing if they succeed in making tunnels far cheaper than they are anywhere else in the world?

Finally, I hope that my tone does not come across to you as being negative in any way. I do not mean to sound strident, overconfident, or for any of the above to come across as a put-down. I mean no harm!

Theoretically yes. But in practice most possibly no. OpenType tables just feature fixed length strings matching. It can't match to more powerful regular expressions. You would need an infinite number of OT rules. [0] If you'd have a well defined set, maybe it could work, but it would still be overwhelming fast.

I have no idea who downvotes such a wonderfully worded and inspiring comment, but surely, those willing to follow the space path and those willing to remain here on Earth should neither deny the other side of their dream nor enact "rules" that forbid it.

In fact, I'm pretty sure both "sides" would benefit greatly from cooperating. It might even be that these aren't "sides" but just different cousins of the family with different outlooks on their own life, and we need a little bit of everything, and everyone, to make a world.
Can anyone explain to me what the benefit of this is over Lombok annotations? I like the Lombok builder syntax which this seems to lack.
Absolutely. NSA has its own fab to guarantee security and ensure secrecy. No reason why we can’t have a corporation that pushes semiconductor tech forward.

I'm sure he was a nice man, and I'm sure you've all derived a lot of pleasure from time spent with his work, much like so many engineers over the years have spent so much time and earned so much of their livings from FORTRAN and COBOL. Because, it must be said, FORTRAN and COBOL are to Computer Science as Lord of the Rings is to English Literature.

So I hope this man rests in blissful peace as earnestly as I could wish it of any good man. But let me go even further and say, if it turns out that if after we pass instead of sleep we are instead subjected to involuntary cage-fighting in our area of expertise, I earnestly hope that this nice man is not put in the cage with the recently departed literary critic and scholar Harold Bloom, may he also rest in peace having left us a cultural hole that's more than 6 feet in every dimension, but not as big as the "new ones" he and his friends tore in Lord of the Rings.

IMO, to whatever extent the reverence exists, it is unjustified. The films are about as good as one can reasonably expect from big budget blockbusters, but to me they are somewhere between mediocre and merely decent cinema, with bombastic manipulative music, jarringly incongruent moments of lowbrow humor, lots of very fake-looking CGI, over-the-top almost comedically grotesque orcs, cheaply emptionally manipulative scenes like the Gondorian charge against Osgiliath, etc. They also have many good moments and many good filming decisions, but I wouldn't hold them up anywhere near the pinnacle of cinema. Don't get me wrong, I think that the books have many flaws too, although I like them a lot. I wouldn't say the books, good as they are, are at the pinnacle of literature either, although they may certainy be near the pinnacle of worldbuilding and are, I think, much much better than the films.
Show HN: A monadic reasoning around function composition in Golang
The satellite is in orbit. It requires significantly more energy to put something in orbit than merely reachin that altitude. Satellite killers are relatively small rockets that can use a small supersonic fighter jet as first stage, while it requires a much bigger rocket to put a satellite in space (it would depend on the orbit of course).

It is true that spacex can put a significant amount of satllites in orbit witha single launch though, so it probably evens it out.

At this point, this is one of those policies which is both environmentally friendly and makes piles of economic sense. Even without clean energy subsidies, coal is rapidly becoming a bad investment. The cost of running existing coal plants has exceeded the cost of building new solar & wind power plants. Over the next few years, demand for coal is likely to implode.

As bankers and insurers start to internalize this idea, the number of people willing to continue investing, insuring, or financing coal operation is going to vanish and the industry will collapse completely.

> It’s not showing up in fatality rates.

Fair, it does seem like the overall statistics don't show this. I'm having trouble squaring this with the data showing that these technologies are preventing accidents.

> Granted, driver behaviors may be getting worse

I wonder whether the top quartile is getting significantly better (thus resulting in the great "crashes avoided" numbers that these technologies claim) while everyone else is getting more distracted with their cell phones, causing an overall increase in the average number of crashes.

This goes into a bit more detail, suggesting that pedestrian fatalities due to more SUVs could also be driving the increase in fatalities: https://www.theverge.com/2018/10/3/17933536/traffic-death-cr...

So it could also be a "safer for me, more dangerous for you" situation too with these new vehicles.

Agreed. Assuming we avoid extinction, it's not obvious we'll be able to recognise ourselves a few hundred years from now, never mind a few thousand. And a gulf of a few million years would be utterly incomprehensible.

In fact I'd be very suspicious if recognisable alien life appeared and knocked on our door, because it would literally be so astronomically unlikely I'd be skeptical about taking it at face value.
Oh cool. I hadn't heard of any of that. Thanks I'm going to check out some of this old school tabletop revival.
Big Bertha is roughly 25x the size of boring company's tunnel borer. And, while your math it totally wrong for Big Bertha, it should be 0.5 miles/yr. But if you account for the 2 years that it wasn't running for repairs then it does end up at roughly 1.3 miles/yr.

Why not compare against a tunnel borer of the same size?

The world's fastest tunnel borer of that size was for the tunneling of the blue mountains (described here: https://www.therobbinscompany.com/the-worlds-fastest-tbm/). That was more than 25 years ago and even at it's average speed over the whole project, it was doing 1800ft 4 times faster than Boring company's "amazingly fast" borer.

A more typical example boring through very hard rock does ~700 ft per month: https://www.therobbinscompany.com/midhalton/

Or how about a larger tunnel w/ 160gal/s of water inflow doing 1600ft in a month: https://www.therobbinscompany.com/gerede-breakthrough/

If there's something special about the Boring company (unlikely) it's definitely not its boring ability. They just buy a used boring machine and they don't even have the expertise to do anything interesting with it.

> One of the things that Game of Thrones got right is to realize that a novel corresponds to a dozen hours of screen time, not three.

But if LoTR hadn't accomplished what it did in its three hours, I don't think GoT would have GOTTEN its dozen hours. I think people underestimate how massively speculative fiction movies (especially fantasy and comic book adaptations) have improved in the last 20 years.

If you compare Jackson's LoTR to Ralph Bakshi's 1978 adaptation, they simply don't play in the same league at all.

It's important to note that the torpedoes Japanese generally used we powered by compressed pure oxygen, making them faster & giving them more range.

But it also turned them into even bigger explosion hazard than normal torpedoes when the ship caring them is hit. As a result many Japanese ships are documented going down after what would normally be minor hits due to their oxygen torpedoes exploding and causing massive damage.
Yes!

On the plus side, SpaceX is making launches much bigger and cheaper, which will make space-based telescopes much more affordable. Cheaper launches = more, cheaper satellites.

ML was better than most of its successors, including Java, which held programming back. Milner's ML avoided some of Java's glaring mistakes (e.g. exception specifications, lack of generics, non-uniform treatment of types, lack of higher-order functions, lack of pattern matching) from the start. Xavier Leroy showed how efficiently to compile ML in the 1990s.

The main thing ML lacked (w.r.t sequential computing), was a good integration with OO and HKTs. That was solved by Scala.
Respectfully, with full benefit of hindsight, do you think it would have been better if you had stayed at Mozilla, forcing them to either fire you (which would have been illegal) or learn to deal with dissent? I ask not to criticize but to strategize.

If you use a migration tool that works at the database level rather than the model level, the the migration handling of views will be automatically supported.

Some people are also mourning the absence of Tom Bombadil. Maybe Jackson was saving him up for a separate movie.

Do you mean using something like `pg_cron` instead of calling it through Scenic and a cron fired at the app level?

I personally don't like having my cron distributed in different areas. All my crons are in one place/system like easycron.com or setcronjob.com or whenever. Performance is not a consideration when deciding to run the job directly from the DB or the App.

I answered the question sentence directly, but maybe that's not what you were asking?
> Thinking about the fact that people like this are out there makes me paranoid about my hiring all over again.

To be honest, I was 100% trolling or troll-baiting "for the lulz" - I wouldn't actually ever apply my "advice". And I don't think there's actually a significant chance of coming across people thinking this way in your business unless you work in very specific areas.

I mean, sure, some of us enjoy to destroy/break things or to make them fail or fall apart for either "the fun of it" or "to leave space for future better things", but we do it in "special controlled environments" to get our kicks, not in our business/work. Unless you're in the military or a similar business you wouldn't ever be in the position or hiring people expected to manifest their selective-destructive tendencies at work and have the risk of them also occasionally turning the gun in the wrong direction.

The biggest problem for a business imo is people who actually do this but do it subtly and unconsciously: like the developers picking "interesting" architectures and technologies that end up destroying the possibility of integration with legacy services and indirectly forces an expensive rewrite of those legacy systems, the managers that adopt "novel" management systems that end up pushing valuable people out of the company etc.

People that are consciously doing sabbotage and destructive action (even if it's "to make the world a better place" in their views) are easy to spot and handle (eg. legally), and those with the competence to really do things stealthly are always more motivated to apply such skills in other areas... the other "damaged apples" doing it without fully realizing are dangerous for businesses and you need to worry about them when hiring...
I may be wrong, but I think they are all different forms of clinical trials.
Coming from scala, I consider this an essential language feature, and I don't want to have to depend on a third-party library / compiler plugin / annotation processor to get it.

I don't have an answer to that question. At least, not a better one than than some vague "it will build character." Do you have another answer in mind?

Something I've been wondering about is the effect of typewriters and word processors on the development of penmanship. Has the average penmanship of a highschool graduate improved or declined with the proliferation of these technologies in schools? Has anybody researched this matter? I have my suspicions, but they're only suspicions.

Supposing it got worse though, would that matter? Maybe the dexterity/coordination skills are transferable. But if that's the case, has that manifested in any apparent way? And if not, does it really matter?
You're absolutely right and I should've stated the caveat that you have to know your body. There's a difference between some discomfort and something really being wrong. I have enough experience to know when it's the former and when it's really time to pack it up and go home. If I can't execute with perfect form, I stop. And I'm always reducing the load a lot when I'm rehabing something minor. Never be a cowboy.

You really just have to know yourself. It's easy to just to convince yourself to refrain with the excuse that you're injured or whatever when really it's just laziness - only you can know the reality if you're honest with yourself. Also, just because you can't deadlift doesn't mean you can't do SOMETHING else. It's rare that you cannot move at all and some movement is better than nothing.

Been there and I see it time and time again with other people, usually when they have back problems. It's sad to see. I'm empathetic and understand why people feel that way, but "putting your feet up" for an extended period of time is almost always the worst thing for you. If/when I get some minor tweak, I make sure to get back to moving as quickly as possible.

(Though I suppose two probes would have to accidentally land on the same planet to lead to that outcome.)
Goes to show we just don't have the Math to understand large scale solutions to differential equations for the N-body problem.
But some of us are using the word 'consciousness' to refer to the existence of subjective experience. It may be impossible even in principle to get very far on most of the deepest questions about consciousness in this sense. But it's still real, it still matters a great deal, and we still make important decisions based on our best guesses.

(Why should I care what happens to other people, and try to avoid harming them? Because they're clearly conscious, capable of joy, suffering, etc. What about other animals, like dogs and cows and chickens? That seems pretty obvious too, given our biological and behavioral similarities. What about molluscs? Hmm, there are some potentially important differences there. What about rocks? I can't know, but they have none of the features I usually associate with consciousness, and if they do have internal experience I have no idea what determines it, so I might as well continue to assume not.)

As soon as you define consciousness in functional terms, you make it tractable, but you also detach it from the thing we were originally wondering about. (The problem is that purely materialist or functionalist explanations always run into the question 'but why does there have to be internal subjective experience associated with these things/events/systems, and not others?'. Consciousness itself, in the 'qualia' sense, never plays a functional role in these explanations -- and if we weren't already assuming its existence, they would give us no hint that it exists.)
could they put an LCD in front of it, and block the relevant pixels as a satellite passes?
The spine is the central structural pillar of the body not only mechanically, but electrically as well. Messages are passed between body parts using electrical signals through nerve fibers, which run from the brain down through the spine branching out to the rest of the body. When these things get messed with, even a little bit, it creates enormous effects.

The spine is surrounded by a system of muscles, all of which work in concert to support your body as you put it through various positions and movements. Depending on how these things work together, certain areas of your body may experience more stress and strain and break down. Muscles become tight and overworked, soft tissue cushioning degrades, and nerves become pinched, stretched, or otherwise compromised.

The way that this manifests in any individual's body depends a ton on that unique individual. There is a bell curve distribution to the way that people's bodies work, but just like taking general technical advice and applying it to a specific problem without understanding what makes the advice applicable to a specific set of circumstances can have disastrous results, so too can it here. Taking general purpose mobility, posture, and injury prevention advice without understanding the mechanics of my body is actually what led to my back injury.

The mental factor of the condition is certainly the biggest hurdle. What helped me deal with two major herniations at L4-L5 and L5-S1 was becoming educated on not how all back pain works, but on how my specific back pain works. It makes you feel as if you own the injury, not like it owns you.
The author's later paper describing the Alto OS they built:

The distinctive features of the Alto OS are
Its open design, which allows any part of the system to be re­placed by client program ..."
If it is deserved, that is, based on truth, then it is not an insult. It is up to the individual to be honest about it instead of feeling offended. I do agree that merely saying they are bad programmers is not enough and it is more productive to also show them how they can improve.
I can tell you exactly how it happened: someone thought that this was the most expedient way to do something they wanted to do, they unfortunately had rights to do it, and they just did it without considering for a minute the consequences. Happens all the time.
Indeed. My wife broke her back in college before we met. Since then she'd had chronic back pain and she figured that's just what she'd have to live with. What fixed it for her was hip thrusters, which are targeted toward the glutes, but also work the lower back to some extent.

To that last, I've wondered how much glute weakness is the factor in back pain. I don't know why it necessarily would be, but a long time ago I saw a study where high school kids with chronic back pain were 100% cured by quadruped hip extensions. Of course, those also work the back to some extent, but it's another exercise that's prescribed for the glutes.
