That SpaceX continues to exist despite now launching approximately half of everything to space by both tonnage and discrete launches — as in, beating not just all the other US launchers combined, but also the combined national/international launches from the EU, India, China, Russia, etc. — says that SpaceX has, in fact, dropped the price to orbit. Likely by more than implied by the price tag on the website, even though the price tag on the website is itself a significant price reduction from most everything else.

"""NASA’s space shuttle had a cost of about $1.5 billion to launch 27,500 kg to Low Earth Orbit (LEO), $54,500/kg. SpaceX’s Falcon 9 now advertises a cost of $62 million to launch 22,800 kg to LEO, $2,720/kg.""" - https://ntrs.nasa.gov/citations/20200001093 (Publication Date, July 8, 2018)

The current price on their website is slightly more for slightly less, $67 million for a 22,000 kg on a Falcon 9[0], and doesn't list the Falcon Heavy; the older archive.org version of the same page says the Heavy costs $97 million for 63,800 kg to LEO, which is $1520/kg, which is (to a rounding error) the number used by other reporters[2][3].

Also just in general the idea of at least being worst case optimal (polynomial faster multi way join-project w.r.t. input rows, assuming fixed query (but those polynomials are given by concepts like the "fractional hypertree width" of a query) but pathologically connected/connecting input rows to the join):

the simplest example is a simple two-column table of a directed graph's edges, e(from, to). Then:
Triangle(a, b, c) := e(a, b), e(b, c), e(c, a).

#Triangle <= c * (#e)^1.5, for a small c. (I think c = 3 in this case, but I'm not sure.)

Using binary joins for pathological input will however take O((#e)^2). If you do row-granularity lookup using an auxiliary index (actually 2 in the simplified way, but they can be merged by pushing the post-lookup choice down to index creation) along with indexing e twice (once for each of the two columns), you can do it in O((#e)^1.5):

Create auxiliary indices eaux1 and eaux2:
eaux1(from, (#e(from, to))).
eaux2(to, (#e(from, to))).

Iterate over e(a, b):
Look up eaux1(b, ?countbc) and eaux2(a, ? countca).
If countbc < countca, then:
expand through point lookup e(b, ?c). Filter those resulting e(?a, b), e(b, ?c) candidates using a point membership query suitable index of e(c, a).
else:
expand through point lookup e(?c, a). Filter those resulting e(a, ?b), e(?c, a) candidates using a point membership query suitable index of e(b, c).

Done.

As can be seen, the trick is to select between the current options for "next table to join current partial row against" at each nesting level of the generally nested-loop-join structured query execution, using premade indices that reveal the iteration count of the upcoming inner nested loop in O(1) time.
Really? Then why does it always end up making headlines whenever a company does so?

I wouldn't be surprised if his internship offer came with a long contract full of small print, one line saying that they can withdraw the offer at any time for any reason with no compensation due. You can usually recover "thousands" on small claims, but I find it very unlikely for that to actually happen - Tesla will claim that the intern should have got something temporary (hotel, motel, airbnb) until he was actually working on the internship.

Vanguard supports accounts that holds mutual funds (most of their focus/business) but also has accounts that can hold individual stocks.

In the individual stock case, Vanguard absolutely has to allow those share owners to vote their shares.

In the mutual fund case, Vanguard is the investor in the shares and Vanguard is the one who should cast the vote for those shares. End investors are invested in the mutual fund, and so could vote on mutual fund proxies, but IMO, should not be permitted to vote on the underlying shares that the mutual fund is invested in.

>SQL is a cool solution for a set of problems that has a very non-zero xor with a set of problems that we actually have.

My usual problems are:

1) Running queries manually, where SQL is much more friendly than writing bytecode by hand.
2) Running queries using a clueless ORM that has no idea how to optimize them, so leaving this job to the database makes sense.

I believe the actually rare problem is "writing hyper-optimized complex queries tailored to the current state of the database", where bytecode would help. But that is a very unusual usecase.

Maybe there are shops that use databases very differently from me, but it makes sense that SQL is optimized for the common use case.

And since db internals are very different, it's hard to make a single bytecode standard that makes sense to use across different databases. You can probably write something specialized for sqlite or postgres, but since nobody did, probably it's not as useful for other people too.
I think we are saying the same thing: based on IQ tests my father, on average, could easily beat people on their 20s and this is not related to any advanced math or language education. He has a better education and, probably, better epoch for learning than, in average, young people now.

I don't want to focus on his math mental skills but his overall education was better. He can also beat people in language/words associations.
A coworker of mine was punched on NYCT. Went to the cop in the station, who did nothing, and was sore for a week. This is a case where it was ‘reported’, but the cop said they couldn’t do anything if he wasn’t seriously hurt. My other NY coworkers have similar stories of other people they know.

Maybe random minor violence is up, but major violence is down… but the number of people I’ve heard of getting assaulted has definitely increased since COVID.

The number of ‘we can’t do anything’ stories I’ve heard have skyrocketed. If anything pre-Covid cops were to quick to go after people. I got jumped after high school by kids I didn’t know and just got a black eye; the cops went and roughed up the gang of guys based purely on me saying ‘that’s them’ as we drove past.

Fully agree. This person states how they have joined and left many social media networks over the last 30 years. They often quote the same reasons for leaving them (comment toxicity, it not being 'fun' anymore, etc). However they dont seem to have identifdied the common factor here, they they themselves dont like anonymous negative comments about their posts and content.

As you have pointed out, there are tools and ways to mitigate this, primarily blocking replies from people you dont follow.

I've used XMPP ~2 years ago and also set up my own server (prosody), it was a really good experience.
Lightweight, Fast, reasonably secure way to chat with some friends.

But I switched to Matrix a year later, not because I liked Matrix more, but because there was no one using XMPP besides me and some friends, everyone else (foss projects and maintainers) was on Matrix.

I really would love to use XMPP again, as prosody was a brease to set up, never made problems and was really lightweight compute and storage wise.
My Matrix homeserver (Synapse) uses 10x to 500x more RAM and CPU ( + the added CPU and RAM of my postgres istance) than prosody did, and its database is at least 10GB now (prosody used couple of MBs). Receiving and Sending via XMPP was also way faster than Matrix and large rooms on XMPP did not take 60+ seconds to load after you didn't check for a while.
Similar to OP if information is low density like a legal contract I can do 1200wpm after a few hours of getting used to it. Daily normal is 600wpm, if the text is heavy going enough I have to drop it down to 100 wpm and put it on loop.

But then we do operate trains in our atmosphere so this is a solvable problem. The advantage outside of our atmosphere is of course that aerodynamics don't matter, which indeed would make things more energy efficient. Also there would be no weather (or very little of it on Mars), no humidity.

> eSpeak NG uses a "formant synthesis" method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings. It also supports Klatt formant synthesis, and the ability to use MBROLA as backend speech synthesizer.

I've been using eSpeak for many years now. It's superb for resource constrained systems.

If not did you goto one of the top strip clubs in America? that sounds insane. Haven't been to a strip club in a real long time myself tho (absolutely don't have the income nor desire).

I think top golf is an interesting metric; I'd be concerned about linking it to two things so addictive - golf addicts and alcohol consumtion. But with the prices at top golf and how much the drinks cost it's probably a good indicator of the sector.

One of the downsides of it might be it only targetting people in upper income brackets (golf is an expensive game per se, def not as everyman and top golf isn't really accessible).

Then again I can't think of any metric that wont be "inflated" by more well off people consuming something cheaper and less well off people having to use another option (aka mcdonalds).

> A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease.

With viruses and bacteria the immune system eventually catches up and vaccinating tends to be done before the host is infected (rabies vaccination is an outlier since it still works even after infection during the latent period). With cancer the immune system usually doesn’t recognize the threat which is why vaccinating after the fact is still effective.

> because his generation had a better general education in math than the people at 20s.

Which we hear a lot these days but which is extremely difficult to prove. Formal education only helps you so far and only for some small percentage of students.

I had access to what you mean by good math education through school and University, had private tutors at school and so on. I can say that with my peers there is a huge spectrum of innate math abilities. Only about 5% probably absorbed naturally everything we've been tutored through the school (1-2 persons in a class of 30).

I am not gifted with math, so I have OK formal knowledge, however few of my friends who worked in humanities all their life are much better at "head math" than I ever was.

Also, I live in a country which have aggressive math curriculum from young age. Looking how my kid goes through it I can say for sure, that it is massive waste of kids energy to be pushed for general population.

I think this is why they are moving into robotics. They're close enough to solving autonomous driving that they've sign-posted that it's a tractable problem for everyone else. We can reasonably expect the other major manufacturers to catch up and once the technology is widespread and EVs are the norm, Tesla has much less of a competitive edge in their core market.

There will be tipping points where it's consistently better than humans so long as there's someone supervising, and then again when it's better without someone supervising. Beyond that point it's just incremental changes.

Inverted pyramid structure is a useful tool.

Sometimes it's inappropriate, and ultimately the author is the best judge of this.

If you view text composition as a UX problem, it will help you figure out when to use the tool and when not to.

Examples where it isn't used (clickbait headlines, recipe blogs with three pages of meandering before they get to the ingredients, SEO "optimised" youtube videos) are, IMO, examples of dark UX patterns more often than not. But your use-case may be valid.

(This comment written using an inverted pyramid structure).
Yes. That is true. There are a lot of stable points, and gov/corp configurations. Really, across history, there are a lot of different forms society can take.

I'm just reacting to the current push in the US to drive down the lower and middle classes, and funnel so much wealth to just a few. A lot of this is done by wage suppression, so that corps can have higher profit.

Jaunt Labs | Full-Time | Full-stack engineer | REMOTE

Jaunt Labs is in the process of disrupting the professional content sharing landscape, focusing on documents, presentations, and more. Currently in our alpha launch phase, our momentum is building rapidly. Plus, our founders come with a track record, having successfully built and sold a startup in a similar domain. We aspire to become the platform which democratises knowledge and discussions around it.

We're actively seeking full-stack engineers to join our distributed team. With Django at our core, we're building scalable apps that can handle the demands of our network. On the frontend, it's all about ES6, no frameworks required.

Here's the structure: while autonomy is key, we touch base a few times weekly, typically around 9AM PST. You'll need at least an hour or two of overlap during these meetings.

Why consider us? Beyond the exciting work we're doing, you'll be part of a cohesive team, tackling challenges collaboratively and driving real change.

Interested in being part of our journey? Drop us a line about why you would like to join us at troy [at] jauntlabs.com or reach out directly to our founder at jon [at] jauntlabs.com. Let's build something remarkable together.

Excuse me but what is HN about if not sharing your work that you worked on?

Oh, it's also about startups. And about funding them. And building stuff people want.

I don't know man. Every time I put in a lot of work (a decade, say) and build something major and substantial to improve the world, and document it, linking to third party reputable sources for everything I'm claiming and saying, and give it away for free... if I share the link on HN, I often get downvoted. It's almost as if talking out of your ass and NOT doing anything to solve the problem, is far more appreciated.

Like how people regularly complain about everything related to extreme centralization of control, surveillance capitalism, etc, and I built open source and free software give you an alternative, attracted millions of people in over 100 countries, and give it away for free to you here if you only look::

Web2: https://github.com/Qbix/Platform

Web2 Documentation: https://community.qbix.com

Web3: https://github.com/Intercoin

Web3 Documentation: https://intercoin.org/applications

But it gets downvoted because "hey I saw the word web3!" or "hey you're selling me... um... something". This is the "TLDR" generation.

Don't like it? Don't use it. Or use the part you like. But how about the 99% of the useful, substantive information which doesn't involve selling anything at all?
Yes: on Earth I imagine this isn't possible (the required centrifugal force to generate the friction needs you to be travelling much faster than a human can run), though I haven't done any calculations.
Possibly dumb question, but if you wore weighted vests (for example) to match the same force due to gravity on earth for that individual, would that be equivalent to existing on earth without the vest? Ignoring e.g. the difference in exact distribution of the weight.

afaict this is novel research that has found a “default application loop(?)” in our brains that is associated with being awake … and differs from goal oriented states - i have wondered if/when such an inner loop would be found since it is quite easy to turn consciousness on/off (sleep, anaesthetics, drugs ymmv) and then fMRI can be used to find differentiated activity patterns. This is pretty good evidence that Panpsychism is bollocks, if you needed it.
