I thought my CS education at UC Davis was pretty worthwhile. Just learning C and C++ in those two intro courses was really useful for understanding everything built on top of those in a modern stack. The seams show all the time.

That said, I spent a lot of time building extracurricular websites in my spare time, which was also a huge leg up in my future career.
It's funny to see a blog post on HN almost every day where somebody rediscovers the power of columnar query answering engines which are almost the opposite of graph databases.

I've lost count of how many columnar SQL databases have been donated to the apache project and there are so many systems like Actian and Alteryx where data analysts hook together relational operators with boxes and lines.

I had a prototype of a stream processing engine that passed RDF graphs along the lines between the boxes that enable an "object-relational" model, you could eliminate the need for hard-to-maintain joins but I found that firms that had bought multiple columnar processing database companies believed in performance at all cost and couldn't care less for any system that couldn't be implemented with SIMD instructions.
>Over the years I've observed brilliant students who do very poorly in IQ-type tests. But they write brilliant long-form essays.

And how big of a sample size are you talking about? SATs and IQ tests are highly correlated. Same for school performance and IQ.

I've been using the 2030 scenario throughout.

Can you provide a source for hydrogen electrolyzer cost? My quick google didn't show obvious results, though there's plenty to dig into.

Certainly nuclear looks bad if you use the worst costs available. My claim is that South Korea, for example, has achieved much lower costs in production, so our issues are more with mismanagement than the technology itself.

If I plug your hydrogen cost into the scenarios in my other new comment, it lowers the cost at which nuclear starts to appear on the US grid, but there's still a point within the range of the world's production nuclear costs where nuclear takes over.
Do you still have interest in other things like reading, movies or exercising? Or its a general dullness?
Nice! I wrote something similar for Next.js a while ago. The pattern is so much more ergonomic than everything else I've used before.

author of the piece here! I think these tools are best understood as a step in an artist workflow that people will use to varying degree. Many painters use photography or sampled images to audition compositions, for example. Musicians use samples to spark an idea or set a palette for them to create within. The satisfaction of creating on a blank canvas won't change, but most artists use tools to help them realize what they want to create, and these are incredibly powerful to that end.

I think that typing to create imagery is cool, but also agree that the ability to instantly create convincing images (with those images being considered the final work) is not the most exciting/rewarding part, at least when those images are isolated as singular works to consider(like in painting) and not part of a greater narrative. This perspective was part of our motivation to frame the subject differently!
I think we'd all be better off with more of this kind of thing. Basing your business on "ownership" of ideas or insider knowledge about some topic which can be trivially shared is a poor quality base for profit. So much of our economy is based on charging a lot to do something which would be quite trivial if the "how to do it" information was open.
Always thought the 'nudges' often referred to in these experiments would only work if participants were unaware of their existence. If participants become aware of the fact that they're being 'nudged' one way or the other, then their reaction will depend on whether or not they have issues with authority, whether they value their freedom enough to fight for their right to have an independent opinion free from manipulation by other actors, and probably a few other factors.
If you currently work for a tech company that runs on VC cash, the time to look for an established profitable enterprise to work for is yesterday.

>we are literally clicking on images filled with text as a way to share… text.

In this case, it sounds like the original post was removed, so the only thing left would be images types of things. Also, does an image/screengrab add any more validity to something rather than text quoted on another page/site?

Correct me if I'm wrong, but it seems like Stripe just nuked the whole of Plaid's platform and value proposition from orbit.

Plaid just went from a decacorn to a cheap acquisition target for PayPal, Square, Shopify, etc.

I can understand this being absolutely gut wrenching for the founders and early employees that are still on board. It must feel like having tangible dreams crushed. Not as bad as a cancer diagnosis, but certainly worse than a rejection from your dream school.

100% this. People often ask me "How do you stick with keto? It's such a strict diet." I always answer: "It's actually one of the easiest diets: the answer to most 'can I eat this?' question is 'no'."

There isn't a persistently high cognitive load on deciding what you can eat, once you master the foundational knowledge of eating low-carb.

The author's post aligns with a lot of ADHD narrative. If the author is reading, consider getting evaluated.

That said, why do we spend so much time not being productive? Because we're not obligated to be productive 24/7. It's ok that you're browsing youtube instead of being productive!

You're demanding too much from yourself -- not because you can't live up to it, but because the expectations are too damn high.
I spend many hours on the internet because it is endless source of information plus I listen music when I'm doing research. I can also say I'm not enjoying it 10/10 but I'm addicted to information and I'm in pursuit of knowledge.
No worries – and ultimately, you are absolutely right, it's all down to what you want out of it.

The two things I wanted to flag were

1) watches can have surprising value fluctuations, so they're worth being appraised professionally: just because you have "a model X from company Y dating back to Z" doesn't mean you'll get the valuation right if you try. If Papa were a desk diver at COMEX instead of Arthur Andersen I'd have likely ended up with a 5514 instead, and my six figure watch would be in a safe somewhere, not on my wrist.

2) many companies, when repairing, will not hesitate to add modern components. Rolex is apparently notorious for this, but others do it as well. In the opinion of Rolex, a watch is a watch: your GMT-Master with a Bakelite bezel is no different from a GMT-Master from 2022, it's just out of spec and needs a refresh.

The combination of this has lead to horror stories where people send their watch in for what they expect to be a fairly routine service (cleaning, oiling, etc.) and end up with an entirely different watch.
Nowadays the Reddit admins order the moderators around like unpaid employees and make the mods responsible for enforcing the sitewide rules.
If you’re going to try to formalize the arguments, people aren’t arguing over whether they’re independent variables (or correlated as you say), it’s what they’re conditionally independent based on. If the causal graph is (race —> parents income —> kids education —> kids intelligence), then no shit they’re correlated. But if, conditional on parents income (as a random example, not intended to be exhaustive), race and kids intelligence are independent, then the fact that they’re not (unconditionally) independent is fucked up and needs equity.

There’s plenty of evidence of mediating variables like that that are making things inequitable.
I don't see any inconsistency. Universities still have multi-user unix servers for students in 2022 - at Bordeaux there's a few 64/128 thread ones with as many gigabytes of RAM, which leaves a lot of room for doing work during class. (And most likely they would be running some Debian LTS like Jessie or Stretch)

To do so would be an extraordinary lapse from the principle of central bank independence. Evidence is required.
Unpaywall is based on Crossref DOIs (one-to-one records), and adds information about publicly accessible versions of each work. In theory publishers can register metadata about whether articles are OA or not with Crossref, but the quality and coverage of this metadata is poor in general.

Unpaywall will both check if articles are actually available from the publisher (by following the DOI and parsing the landing page), and by looking for other versions elsewhere on the web (eg, a pre-print). It is simple in theory, but doing this reliably for millions of DOIs from thousands of publishers is a lot of work!
It's common.

We tend to keep doing what we are already doing (an inertia of sorts). If we are eating, we keep on eating (even if we are not hungry anymore) until an external factor stops us (e.g. the food is over).

Changing states (starting/stopping) is the hardest part, but if you trick yourself somehow to stop it's easy to just put the food aside. The question that remain is how do you stop yourself from doing what you are currently doing? Some people use an "1,2,3 technique", where you just count to yourself and once you reach three you start doing what's needed. Mindfulness also helps, where you take a breath and think exactly what you are doing and why (I am eating, I am putting my hand in the bag of chips, I am bringing the chip to my mouth even if I am not hungry and don't even enjoy it that much, this would just make me feel fat afterwards).
Slack is great for resiliency, but it obviously can't be unbounded. The CEO in the article can't have 100 secretaries just in case. One of the great things about approaches like linear programming (programming in the sense of industrial engineering and not CS) is that it helps quantify how much that slack is worth. It can then be put into context of whether the risk tradeoff is worth the extra slack.

I don't think anything policy does is going to cause a recession. We've got a whole lot of QE to wind down before anything like that happens. If a recession hits now, it's going to be due to supply factors: the aftermath of the pandemic and the global situation more recently. Of course, any move towards sustained inflation is also dangerous; it would be good to avoid that.
> Maybe we should have explicitly reached out to them to discuss this upcoming launch so that they could privately express any concerns they had.

A thousand times no. Companies privately discussing launches with each other to avoid stepping on each other's toes is bad for the consumer. In addition, it may actually cross the line into illegal market allocation.

I am glad that Stripe developed and released a product that they thought would benefit their consumers.

I do not want companies feeling they have to consult another company before entering a market. (which once again may actually be illegal).

EDIT:

Maybe I am being paranoid, but the tone of the Plaid founder and the apologetic nature of this post, kind of brought back memories of Steve Job's indignant emails about other companies hiring, and their apologetic response which ended up leading to an illegal agreement not to hire each other's workers. I don't want any "gentlemen's agreement" about market allocation and collusion about what products/services will be released.

This is terrible advice. Any fads are. Ketogenic diets are not good for you in any way.

Bad behaviour starts with acknowledgement and the best way to do that is to track what you eat and learn to adapt slowly and develop self discipline. Use a tracker app and set a reasonable daily break even nutritional target and start thinking about what you eat. Slowly substitute better choices in. Eventually you will develop self control.

People want quick fixes but keto just breaks other things.

There is something in the animal brain that enjoys _variable reinforcement_ more than other kinds of behavioral reinforcement.

I am not an expert, but if something gives you a reward _partially randomly_ -- e.g., the one cool (or otherwise captivating) post on Facebook that sometimes comes out of the 200 you scrolled through -- this kind of reinforcement produces the behaviors most resistant to extinction.

See "Effects of different types of simple schedules" on https://en.wikipedia.org/wiki/Reinforcement.
This sounds like a major depressive episode. A very experienced psychologist recently told me that even folks with no hint of mental health trouble started having a hard time with motivation and mood in the pandemic, but many with existing tendencies towards depressive states were plunged straight into oblivion. Talk therapy and medication can be a big help, but CBT exercises can also help if you're against using medication and can't imagine going into a deep dive about your feelings with a therapist. Even if it's not depression, this poster should talk to a psychologist. They're not able to right the ship themselves which doesn't bode well for it improving on its own. Finding a therapist sucks but telemedicine is more accessible than ever at this point.

As an aside— folks love dismissing mental health concerns by saying things like "everybody has a hard time getting motivated." That completely ignores the scope of the problem— it's no different from telling someone their motorcycle accident is no big deal because kids fall off their bikes all the time. There's a boatload of peer reviewed research out there that discusses the debilitating effects of depression. Go read it if you're skeptical— I'm not your research assistant.
I agree with this. The time spent in app is roughly proportional to the number of ads watched and the revenue.

I noticed this shift shortly after when the internet connectivity become ubiquitous, in late 2000s. The older software designed to work offline may be clunky by the modern standards, but it honestly tried to meet the needs. There was an economic incentive for that too: a satisfied user is more likely to buy the next version or recommend the program to friends.

The connectivity and easy online payments have created new sources of revenue that are tied to how an app is used - the microtransactions and ads. It is inevitable that the dark patterns have followed. It is admirable when a business chooses a more ethical business model at the cost of revenue, even if the most users may not recognize it. But it will never be widespread until the structure of incentives changes. Zerodha has a better standing to do this choice because the stock brokers have revenue largely independent of the engagement.
> If he's not a genius, then no musician is a genius.

Maybe there’s no such thing as genius. Maybe what we call genius is the synthesis of many people’s work, or luck, or both.

Not to say Paul isn’t an incredible musician. Just that maybe the Beatles were genius, not any single member.
What are the qualities of a startup engineer?
Sure, I'm using a multi-user Unix server right now in another window. The key point was that there was just one server for all the undergraduates. (And that they had to worry about a private install of GCC using up their disk quota.)
I likewise broke it, bravo!
> so, what was the answer, from the lecture? what had you missed?

He never told me and I was too flustered at the time to ask. Which was agonizing because I replayed that damn interview in my head for weeks afterward wondering where I went wrong. (Aside from slightly losing my cool, obviously.)

I didn't get the sense that the answer he was looking for was, "find someone else who can help," or, "bin the whole server and rack a new one," because I remember it being either stated or strongly implied that the hypothetical server did have some problem that could be resolved by a tech at my level. But I could be mis-remembering things, it was a long time ago.

But like I said, in the end it turned out to be a good thing that I didn't get that particular job. At least the interview itself was a very valuable learning experience and I'm grateful for that.
Ask HN: At what point do you expect companies to failover cloud infra?
Google Cloud has been having a major outage for more than 10 hours now. Some products built on Google Cloud have been down that long, too. Considering the outage was only 1 region, at what point, if ever, should we expect the products built on Google Cloud to fail over to another region to mitigate impact?
Is VC cash "debt dependent", though? My impression is that it is not.
> Asian students whose average SAT scores are roughly 20% higher than the population average

This wasn’t always the case. For a long time Asians scored below White Americans. However the former’s average scores have surged while the latters have stagnated at best. I don’t think there’s a single clear explanation for the surge in Asian SAT scores, but cultural issues like enthusiastic parenting as well as test prep and tutoring are almost certainly significant contributors. The effect of tutoring on academic achievement is massive, as much as two sigma.

Whatever it is, Asians found a way to greatly improve their average scores, so if we want to increase diversity without lowering standards it would be best for other groups to adopt similar or better preparatory strategies.
Spin. Everything that has gravity eventually spins, so spin produces gravity and gravity produces spin. Even the moon spins, so I must be right.

Also, if you spin someone in a barrel, it produces a force that is indistinguishable from gravity, for the person in the barrel. Simple, but scientists like to make things complicated and confusing. Probably makes them sleep better at night.

See Newtons bucket argument. Spin is relational to the universe. If something spins, it produces gravity gradients. These come from differing frames of reference to time, or more specifically, variance in the pace of causality.

> Why do you waste so much time on the internet?

Because our brain doesn't like to get bored. We need to constantly do things. Also, the brain doesn't really like to start doing the right thing because that feels too much like work, even though once we start being productive we do feel good and enjoy it.
Making mistakes is painful. Risking judgment is painful. Respect to everyone who is able to walk through the pain even for a little while.

“Flamingo does feel slightly conscious these days”
Anecdotally I know a lot of people who are too ashamed to admit they're mining on it in their spare time but know that leaving a money printer that makes $5 a day sitting idle is stupid. ;)

(even today, a 3090 is still profitable even with absurd $0.30/kWh electricity or whatever - if you are around the national average of 10c they're still doing like $3 a day. Not "buy 10 of them and build a rig" profitable anymore, but at the peak they could do ~$11 a day after electricity and for a long time they were $5 a day after electricity. Pre-LHR 3080s were a beast too, almost the same hashrate as a 3090.)

Anyway the backlash against mining and miners in the 2021 timeframe was real and intense. I'm not saying there aren't legitimate reasons - it's a waste of electricity, it's screwing up the market for everyone else, etc - but I think a huge number of gamers who bought cards in the 2020-2021 timeframe mined on them when they weren't using them and just don't want to admit it.

Unfortunately, crypto is a memeplex, it's like a corporation, it's a self-reinforcing living entity that supports itself (maintains homeostasis) through a series of rules and incentives, and now that it's been created it can't be easily killed. Every individual is financially incentivized to keep playing their part, so everyone would have to collectively agree to not make money by taking part, and as people fall out the incentives become steeper and steeper to participate. Would you mine on your card for $100 a day? $1000 a day?

Even if you pulled the plug on the exchanges, crypto is far enough along that it would be self-sustaining simply based on the black market. And the existence of PoS paradoxically makes it impossible to ever kill the PoW coins, because they can be traded on decentralized exchanges even if the real money exchanges ban them.

We will just have to live with destroying our planet, because now that it's been created it's virtually impossible to kill. That was the whole point. With apologies to Alien: it’s biologically engineered to be a survivor... the perfect predator (of certain other memeplexes).
Exactly? Did he? Looking at the site that is linked or quoted to doesn't exactly instill confidence.

I don't think OP is implying all time on the internet is wasted. Or that we are meant to always be productive.

Speaking personally, I think all of the time I spent gaming and "hanging out" in specific internet/gaming circles when I was younger was hugely valuable. I think some portion of the time I currently spend reading HN is valuable.

But there are absolutely times where I want to be doing something productive, to be accomplishing a task, but I mindlessly browse the internet instead.
