Sure, the physical reality of the singularity is a bit of a mystery as it comes up against the nature of gravity at an extreme which requires a quantum theory which includes general relativity, but that is a known unknown and not what any of this black hole physics is about.

Outside of the singularity, and definitely outside the event horizon, a black hole is a very real thing which has been seen and measured in "empirical reality" and theory has so far matched well with measurement.

Nobody is going to Euclid and claiming a point or line is a real physical entity, anything but a useful abstraction.

But man is it a huge PITA (especially when doing programmatic code generation of the SQL) compared to LATERAL joins

Someone familiar with the CockroachDB query planner showed me that a window function like this is what Cockroach turns LATERAL joins into for instance:

demo@127.0.0.1:26257/movr> explain select * from abc, lateral (select * from xyz where x = a limit 2);

• filter
│ estimated row count: 1
│ filter: row_num <= 2
│
└── • window
│ estimated row count: 2
│
└── • hash join
│ estimated row count: 2
│ equality: (x) = (a)
│
├── • scan
│ estimated row count: 6 (100% of the table; stats collected 2 minutes ago)
│ table: xyz@xyz_pkey
│ spans: FULL SCAN
│
└── • scan
estimated row count: 1 (100% of the table; stats collected 3 minutes ago)
table: abc@abc_pkey
spans: FULL SCAN
I don't know of any "how to write tech. books" kinds of books. I do have some recommendations of good examples of technical writing and right on top of the list is the C programming language closely followed by anything written by Brian Kernighan. The latters relaxed presentation with hard hitting examples drives home points in a way that no other book I've read does.

Like many other folks like the founders of CockroachDB and CoreOS, we read a Google research paper posted to HN.

That's fine, but then you shouldn't give your info to apple at all. Or google, or facebook, or microsoft, or amazon, or ycombinator, for that matter. The fact is, unless you want to be a luddite (which you aren't, you're here, with an account, at least) then you have to trust at least some of these companies. So the question is, which ones can generally be trusted, and which can't? I personally trust apple more than facebook, ycombinator more than amazon, etc. Your ordering might be different, and that's fine, but you're drawing a bright line there, which only hurts yourself.

I understand it's fake (what is the carbon source? it is stated to be CO_2 neutral) but I guess I don't understand the point or punchline.

edit: as pointed out below and elsewhere, the carbon source is CO2, and I misinterpreted the way CO2 neutral is used here, my bad. However there are serious questions to ask about how they are representing and overselling their process. It is a complete misrepresentation to present this as protein synthesis out of air (in fact, the nitrogen source is ammonia [0], NOT nitrogen fixation).

Why do social networks persist as “gateways” to information?

They offer a consistent experience. You’re less likely to be inundated with the random crap found on a random website. People prefer the mediocre, yet consistent, social media “meal” over the fancy meal with possible high degree of variability in quality.
Try to think how dystopian the meat industry feels to a vegetarian or vegan person.

Hooray! Yet another data point for Trino > Presto as far as I'm concerned ;^)
To me, you're overthinking the original comment. The particular line

>Also, steam should never even see the password, they should only ever see the hash.

is, if you interpret it generously, trivially true. There are 101 authentication mechanisms where Steam doesn't "need" to see a password (i.e. some secret information that is remembered by the user.) As you point out, the password can be hashed and even salted before transmission.

Alternatively, Steam could authenticate with e.g. a public/private keypair, in a way that means that it would be immune to replays of the authenication protocol, while never seeing or storing any sensitive info.

But I find it hard to believe that the original commenter's objection to Steam seeing your password is based on any of these alternatives. The comment didn't say "Steam should be using a protocol where they don't see your password", and I don't think many hackers have such an opinion about any service, given how prolific just basic username+password authentication is on the web.

My original reply was based on the interpretation that the commenter had misunderstood how username+password authentication interacted with password hashing, both of which are technologies used in 99.99% of web services - rather than a more esoteric approach which somehow justifies the idea that "Steam shouldn't see your password".
I see a number of people commenting on the size of the proof (roughly 900 pages) which is not uncommon in this particular sub-field of PDEs. For context, I had the distinct privilege of studying under Sergiu Klainerman for my PhD on this topic. My own dissertation was about 600 pages. From my personal experience, I have come to understand a few factors that contribute to large proof sizes.
1. A lot of work is on inequalities involving integrals with many terms. These are difficult to express without taking up substantial space on the page. Some inequality derivations themselves might take multiple pages if you want to go step-by-step to illustrate how they are done.
2. Writing a proof of this size is not unlike building a medium-to-large size codebase. You have a lot of Theorems/Classes that need to fit together, and by employing some form of separation of concerns you can end up with something quite large and complex.
3. Verifying this kind of proof isn't usually done all at once. A lot of verification happens on the individual lemmas before they're pieced together. Once the entire paper is written, verification is more of a process where you rely on intuition for what the "hard parts" of the proof are and drilling down on those. But when writing the paper, you must of course account for all the details regardless of whether they are "easy" or "hard", and there can be many.

Having said all this, I have not read their paper and it has been 5 years since I was in this space. This is a truly remarkable accomplishment and the result of decades of hard work!

I'll end with an amusing anecdote. A fellow grad student, when deciding between U of Chicago and Princeton for his PhD program was pitched by a U of Chicago professor who once said something like "Of course you could go to Princeton and write 700 page papers that nobody reads." When this story was shared during a conversation over tea at Princeton, another professor retorted, "Or you could have gone to U Chicago to work with him and write 70 page papers that nobody reads!"
We are another of Superblocks' early customers, and we've found it really useful for creating internal tools quickly. We still prefer to write some of our more heavyweight tools in React to leverage component reuse, etc, but we like this for lightweight tools that don't have a lot of complex frontend logic.
Google and Bing (and hence DDG etc) are no longer a search engines, they're "information the powers that be permit you to have" engines. Forums, blogs, and small independent websites have disappeared from indexes. Large walled garden platforms like Facebook are impossible to query.

I disagree that there isn't an upside.

In general, there would be more upward pressure on wages if information asymmetry went away. It's especially insidious for folks in the lower class, since they don't realize the extent to which they are being underpaid.
C is the most practical in the short term, because we don't have to understand the brain all that well to find out how to tell an embryo to make it bigger and denser. It will involve a lot of failures.

I do the support for my department's trino cluster. We move ~1tb (and growing) in ETL jobs and support interactive queries for the data scientists/analysts.

It would be super good if you guys added big query write support. Its really annoying to have to run a hive cluster in google to act as a proxy for this.
I've been in a lot of dysfunctional organizations and I've never seen one that took zero engineering estimates. Directors may set deadlines without it but that scope & timeline filters down to the engineering team and then the engineering team plans their time. It's at that point you pad your estimates. Stretch 40 hours of work into 50 hours of estimate and you look like you're killing it when you do 40 hours of work.

Even if engineering has literally 0 planning input at all they're still the ones doing the work. I've never seen a PM sit behind an engineer 45 hours a week and make sure their working. Just stop working and go home or take a longer lunch if you want to work less. They're not going to fire you. The logic doesn't make sense. Firing an engineer on a project behind schedule is going to make the problem worse. Not better.

If you are legitimately worried about being fired you're in the top 1% worst organizations and it's time to move on.

> Don't they realize that having money early in life is important for starting a successful company?

- this isn't necessarily something they want to optimize for

- there's a lot more to growing up wealthy than just the balance of your bank account (opportunities, education, connections, name recognition, not having to work from very young age)

- their children do have money early in life, lots of it too. People like Buffet or Gates have left their children multiple millions of dollars just not all the billions they have.
Not just “traditional SSDs”, which are block-addressable.

A byte-addressable Optane RAM would enable a database that no longer “thinks” in pages, but can independently persist much smaller pieces of its internal structures, possibly leading to new paradigms compared to what we have now. Perhaps write-ahead logs, B-Trees and other stuff can be implemented better when you are no longer limited to writing entire pages?
Any chance you have an overview of the architecture and operations support required? How many data sources are you pinging?
I discovered something like this recently when I tried the prompt "man throwing his smartphone into a river," and for the life of me I could not get DALL-E to render the phone separated from the hand (I tried "like a boomerang," "tossing," "into an ocean," "like a baseball," etc). And then it occurred to me that by the training data, there are virtually no pictures of a person and a phone where the phone is separated! So DALL-E might have thought that the phone was just an appendage to the body, the way the hand is (which, what does this say about society!). I might as well have asked DALL-E to render someone throwing their elbow into a river.

Another interesting case is animal-on-animal interactions. A prompt like, "small french bulldog confronts a deer in the woods" often yields weird things like the bulldog donning antlers! As far as the algorithm is concerned, it sees a bulldog, ticking the box for it, and it sees the antlers, ticking the box for "deer." The semantics don't seem to be fully formed.
I wonder why they had such a thing for pedants.
But even if US citizens dropped per capita consumption to that of avg Chinese citizen, it wouldn't make a difference if the absolute volume of emissions into the atmosphere from China still dwarfed the impact of that change in the US. The point is that, while restricting lifestyles and carbon emissions in the West is fair, it's ultimately pointless w.r.t climate change.
This was some really interesting reading, thank you internet stranger :)
Human intelligence = the standard intelligence we exhibit today as humans vs. machine intelligence from something like ML

Not asking for a normative judgement or a positive one, I asked about what you thought would be the logical progression (under the assumption that humanity would like to continue to evolve and become more prosperous and becoming more intelligent or building more intelligent tools seems and obvious way to help enable that)

Could be more than one, was just trying to give some large buckets, that's why I added D and asked for people to add their thoughts.

> Believing that the greater social structure of your society is controlled by conspiring entities who tend to work in their mutual self interest and to support the status quo will almost necessarily be seen negatively by those who merely support the status quo, which is basically everybody.

Lol… the founding documents of the United States are pretty explicit about not trusting government. Something like 80% of people don’t trust news media today.

I wouldn’t say everyone supports the status quo. In fact I think the vast majority of people don’t like the status quo. The discussion is always how to make it better.

All that said, “conspiracies” are real and everywhere. I have multiple active conspiracies with my friends to go on a trip this fall, wife doesn’t know yet. Lol

My point was actually that conspiracies are all around us. Being apart of them is common. That makes us apart of something and makes us happy. Social cohesion wasn’t exactly what I was discussing, but I don’t think cohesion is actually necessary - so long as everyone tolerates one another.

That said I do see your point. The search for truth is definitely key. But truth isn’t much different than faith. Imo believing truth is a willingness to accept constantly being wrong. You much always change your opinions.
can please help me where can I improve ? Always welcome for inputs.

Thank you.
General Relativity says there is a singularity, more than one depending on the metric and coordinate system chosen.

However GR is not a quantum theory and it is well known that it clashes with quantum mechanics in ways that would show up in a singularity so what the physical reality of space actually at and nearby the singularity is still a mystery because we don't yet have an accepted theory of quantum gravity.
You're probably going to lose it all by betting incorrectly.
Well things certainly get worse after the initial honeymoon ends and the optimistic investment money dries up. I think this is just a sign that it's time to find new hangouts online. Best not to stick around and get monetized as part of a desperate attempt by social networks to get profitable.
Hmm, obviously cyanobacteria like Spirulina[1] "utilize CO2 captured from air" along with "water and some minerals" and sunlight to make sugars and proteins which people can eat. Not sure I'd describe that as 'fermentation' though if you do anything in a big vat it's a bioreactor and not just... a big vat, apparently.

https://www.theverge.com/2021/12/10/22826695/apple-china-mou...

It's an open secret that Chinese authorities have access to all domestic iCloud data without a warrant, which is often used to profile political dissidents and the Uighur populations that Apple relies on to build their iPhones. This is only possible because Tim Cook agreed to move the nation's iCloud datacenters into Chinese territory. So, when Tim Cook says "Privacy is a human right", what he apparently implies is that not all humans are created equal. It's certainly an ugly hill to die on, but it also makes it incredibly hard to believe that Apple has an ideological attachment to privacy when they bend over backwards for China more than any other FAANG member.
Interesting how in `cgit` you can auto detect README files, but the default page for a repository isn't the readme, it's the commit summary history. I'd say it's more "traditional".

Hey ck_one that's a hard question to answer and not get into "benchmarketing" territory.

My suggestion is to try both under your own workloads and see the difference. Trino is also used by products like Athena (AWS) and Galaxy (Starburst) so if you want to play around and see how Trino performs without spending too much time on setting up clusters on your own, you can try these great products.

Having said that, I'd like to add that building a performant distributed query engine is just hard. Trino has been in development for ten years and used by major companies in very demanding environments, these environments is where the technology has been defined and makes it what it is today and it is a proof of its performance and stability.

(edited to add an important disclaimer that I work at Starburst)
Surely with hydrogen it's a fuel cell (and relatively v. small battery for regenerative braking and such), not a battery like a BEV? And as the hydrogen, using a tech like MOF, would be cheaper to store, and easier to store longer term ... the extra energy expense seems a priori to remove a lot of e- waste and reliance on mining in developing nations.

I'm not sure how the life-cycle overall energy usage compares, would be interested in reading a study of someone wants to link one.

I'm hoping that hydrogen storage will become easy enough that we'll use that for large scale excesses like those from nation-size grids during excess production. So we can do seasonal shifting at scale.

We’re Israel & Mario, cofounders of Neuraan (https://neuraan.com). It is difficult for natural language processing developers in LatAm to get their applications to have the same accuracy in Spanish as in English. We create an API that helps them correct those inaccuracies and increase the adoption of their solution.

We have +6 years of experience developing chatbots and voice assistants for large enterprises across LatAm and was very common to end up doing some research and developing algorithms to enhance the accuracy that the commercial solutions like Dialogflow, Watson, Amazon Lex, and Azure Cognitive deliver because they provide a general solution for non-English languages.

I'll like you to try or invite someone to try our API and share your feedback with us.
