The post doesn't really shed much light on it, it feels like a missed opportunity to explain things well.

There's two main effects:

- Negative expected value (EV)[1]. The games are set up in a way that on average you're likely to lose money. This is true for every game where you play against the house, otherwise the game wouldn't be there. Poker is different because your EV depends on how you play relative to other people.

- Bankroll management and risk of ruin[2]. Even in a fair game, if you start with a short bankroll, you're likely to go broke. For example, let's say two of us flip a completely fair coin and bet $1 on each flip. The expected value for both players is $0. Now if one of us starts with $5 and the other $1000 and we play repeatedly, the person with the smaller amount is almost guaranteed to go broke in a long series of flips. This what happens when you play against the house and it's the main reason why people lose money when they gamble in casinos.

I'm no expert, but is extending broadband to the areas that have none really more important than or offering competition in areas that have one? Won't this bring the ability to wfh to areas where people who need to wfh have already left?

I remember reading several years ago that the cost of a 1gb connection in Seoul was $20/mo. There are lots of places in the US where 1/10 of that costs 3x that. If we're going to subsidize infrastructure (and pretend that municipal broadband is evil), that seems like a better target.
Is "we" the united states sending a bill to other countries?
I don't have much data points to share. But I've been seeing responses to people working FB have been horrible since for a while now.

It has been a common trend that when someone I know posts a job position in FB, nobody replies to it. At least not publicly (publicly means replying to tweet, replying to slack message in a well knit/known group of people). Even if they are replying personally and privately, that in itself shows a problem.

When I see someone working in FB, I can't deny that I am judging them. At this point, there is no reason to give a benefit of the doubt to how bad FB is to people, democracy and humanity in general. Sure, you can argue with technical meritocracy of some tech they produce. But how long can you sell yourself that excuse really when on the other side, adverse effects are mounting up?

As nerdy and smart as tech workers are, we are still in need of validation from others right? There definitely should be some effect on people being perceived as a bad person for working for a bad company even if it is paying a ton. FAANG engineers should be more than equipped to look elsewhere because of it.
> We just call this “note taking” in college

Note-taking is just one aspect of the entire process, I even have a sub-heading for that. Calling the entire process just that doesn't do justice to it.

I am extremely cynical about this after Clinton’s national broadband initiative resulted in telecom companies taking $100 billion and not doing anything.

I didn’t see any mention of municipal broadband.
"Want to replace fossil fuels with cleaner energy sources? It won't happen until those alternatives are cheaper"

We are going to go extinct with that attitude - the laws on nature do not owe us a cheaper method of producing energy.

>I think regular GPS is only ~10 ft accuracy

This has not been true for quite a while. The equipment used on surveying, farming, and construction equipment is much more accurate thanks to the availability of multiple GNSSs (e.g., GPS, GLONASS, Galileo, BeiDou) and terrestrial base stations to remove error (WAAS, DGPS).

Hi HN!

I built this website last year for family members who enjoy playing jigsaw puzzles on their computers. I decided to build it because I frequently heard complaints about how slow some of the more popular jigsaw apps are and how they are filled with annoying advertisements.

The site is completely free to use. No advertisements and no selling of user data. However, I do offer a paid tier for users that want more jigsaw puzzles and difficulty options.

On the technical side, I'm using Svelte on the frontend with a tiny bit of wasm, and Rust for a few backend APIs. I hope the site feels snappy, it's one of the main reasons why I decided to build it.

There's a demo puzzle linked on the home page for anyone who doesn't want to sign up! I'd recommend trying it on a computer or tablet as mobile is still a little rough around the edges.

Happy to answer any questions about it!
Got it. Thanks for clarifying. Thought there might be some kind of clever sharding or tooling I was missing.

Hmm... with "reason to exist" I meant the reason why they were "created" in the first place. This is an interesting article that expands on how corporation "rights" have changed since foundation (take the historical data points more than the underlying political bias): https://www.americanbar.org/groups/crsj/publications/human_r...

> Agreed. But i think it's a problem in the system itself. The us have a binary choice between hilary/biden and trump with no middle ground.

Indeed! I believe the problem in the system is even deeper. Regardless of your values or your preferred policies, I really feel hilary/biden/trump is a very poor display for the United States. The selection process that brought them there is not working. Smart people avoid going into politics in the first place because of this selection process. People don't want to spend their days arguing with a guy with bogus claim that is only trying to bring them down.

If your goal is to be good at LeetCode, then save yourself the time and just go straight to LeetCode. Nobody cares if you actually understand the stuff.

If you're interviewing for senior positions, it is worthwhile to read through Designing Data Intensive Systems. This will prepare you for System Design interviews where you do need to actually understand stuff.

I find the writing style in CLRS to be quite readble. Sure the book is huge but so maybe pick and choose chapters but each chapter can be read "cover to cover". Perhaps some of the stack details you are looking for are left to exercises in CLRS? Most good "textbooks" will do this. Perhaps you don't want a general textbook on data structures but want a deep dive article on stacks.

I admit I haven't explored many other books on this topic but CLRS is very good in my opinion.
Chrome, Gmail, drive, Chromecast, duo, call screening. There are plenty of entirely home grown products that have succeeded. Discounting products which have had the vast majority of their growth and featureset built out while under Google is also a but dismissive of it's role in making them successful.
Please stop spreading misinformation.

Vaccines prevent infection, as evidenced by the drastically lower COVID case numbers in the vaccinated. You can’t spread it if you don’t have it. If you do contract it, you are less infectious.

This is no different to instituting lockdowns before vaccines became available.
You still have the problem that this is a textbook Public Good¹, and a textbook Collective Action Problem².

As in, if someone pays $1B to decarbonize, the entire world benefits from it. So everyone is incentivised to make someone else pay for it.

Empirically, things like these tend to be very underfunded.

Are there any public companies actually working on this? The last time I looked it seemed like the answer was “Chevron, kinda”, but that doesn’t seem like the right spirit.
Well no one cares about spread to vaccinated people. No one truly cares about spread except as it affects the health care system. If everyone was vaccinated, all cases would be mild and life could go on as normal. But unvaccinated people are filling hospitals causing disruption to the healthcare system and that effect snowballs.
> Facebook presents an existential threat to the business of most traditional news media and they have a platform that actively promotes misinformation.

I think just as much as that budgets are a big driver. If a game costs a bazillion dollars to make, and making it cross-platform is relatively straightforward, making it an exclusive doesn't make a lot of sense unless the platform holder is handing you a bag of money.
> Obviously the entire reason for a companys' existence is to make money why should we expect anything else?

The way this is supposed to work is that you make flour and I want flour so I give you money and you give me flour. Then you make more money by automating the production of flour so you can sell it to me for a lower price even though you now have higher margins. And try to take market share from competitors who are doing the same thing. The profit motive increases efficiency. This is growing the pie.

The nefarious way to make money is to swipe somebody else's piece. This is rent seeking. It causes prices to increase with no increase in value. It is to be destroyed.

Does instapaper have HN formatting service now (or) do you manually send HN story through it? 'Send to Kindle' extension of Amazon can do the same if anyone is looking for a free option, But 'HN to Kindle' formats the HN page and sends as a book.

Before Obsidian, I tried 'Kindle 2 Notion'[1] to sync My clippings.txt from Kindle to notion, But Notion is too heavy for my liking and I didn't use it for any other purpose.

Obsidian is built upon self-hosting principles, The obsidian-kindle-plugin referenced in the post is useful for anyone to self-host a read-wise type setup.

(Assuming there was anything to take a picture of to begin with:)

At this point in time, how would we authenticate such an image if it did appear? I think the US Government could open a museum display of recovered artifacts and even have things inexplicable and test-able and it would still be reasonable to doubt anything they had to say of its provenance.
Show HN: Morning Brief – Track any topic on HN, Reddit and others
TL:DR - https://morningbrief.ai/setup

Hi, HN --

We're two indie cofounders who bootstrapped a new product to scratch our own itch: there's so much great content out there, but it's hard to find it. Sites like HN serve us like-minded people, but there are many more topics in other non-HN niches.

Our idea is this: an email you get once a day, filled with only top articles (posted to HN, Reddit, etc) that match your specific interests. You can specify which interests, and how many links you want. Ranked by our signal score.

<tech-info>

To start, we built an ingestion engine. In the first few weeks we only processed HN posts (1k/day) then we added Reddit posts (1m/day) then we added some other sites like Indie Hackers and relevant Twitter accounts.

Then we added semantic tagging. To start we used a generalized tagging service, but then quickly realized we needed to build our own layer because they don't understand many of the current trendy topics.

Next up we wanted to add thumbnails to worthy articles (about 10k/day). It became apparent this was going to cost over $1k/month using a commercial API. So we built our own service using headless chrome, Laravel & puppeteer.

Our original plan was to just show headlines, HN-style. But after initial feedback users asked for article summaries. To start we used a 3rd party commercial summarizer. Aside from the cost (appx. $400/month for our needs) we were not super happy with the 3rd party results so we built our a summarizer.

Here's an example of a brief with summaries - https://morningbrief.ai/sent/24960b76-4d494be1-ae822280-14274649 - this example is crypto focused with no thumbnails (keep in mind every brief is 100% custom). Here is another example of a more eclectic brief without summaries - https://morningbrief.ai/sent/377f08da-18f04407-a655d594-b1b3043b

Our stack right now is Python for link processing and summaries, Laravel to grab screenshots, send emails, and be the web app. We use SaltStack to orchestrate infrastructure. We run 13 servers on AWS with a cost of approx. $300/month.

</tech-info>

When we started out we thought this would be a weekend project! Turns out solving timely, personalized, summarized, quality controlled, content aggregation at scale (in a cost effective way) is quite a difficult problem. That's how we managed to soak up 6+ months of our side project time just getting it ready for this Show HN!

Our early users have told us that we've sent them important articles that they missed -- which is exactly why we built this.

You can check out how the brief builder works (without registering): https://morningbrief.ai/setup. We're still experimenting with pricing, but we're trying a 2-week free trial, then $5/mo (annual).

Any feedback would be appreciated!

I'm not sure that's true. For example the video about serving 5 petabytes of data took 11 years to come out: https://news.ycombinator.com/item?id=29082014
moving the pieces cause them to rotate (to the correct position). Doesn't that make the puzzle super easy if you know how everything is oriented?

My a1502 still has Mojave, and I'm not planning on returning to MacOS until they reinstate 32-bit support.

Unfortunately real Martian “soil” is very high in perchlorates, which makes it difficult to grow much of anything in it.
I noticed that:
1. Android phones run a little bit faster after restoring to factory settings and """NOT""" installing apps updates and system updates. Of course they will be obsoleted, but the phone probably will run faster. Hypothesis: [Are apps and system updates too heavy for phones?]
2. Sometimes phones run faster after battery replacement. Hypothesis: [Are phones becoming slower because they do CPU underclocking/undervolting to work with degraded battery?]

His point isn't about the superiority of one method or another; it's that PC games all support controllers and many players choose to use them to play. Microsoft made a pretty hard push for that with the Xbox 360/One controllers.
My understanding of IQ is that its not fully heritable... an individual's potential is maximized by their environment, up to some limit. This alone gives a strong argument for improving public schools especially where students may be falling behind. So I am still not understanding the complacency aspect fully. I suppose a bigoted person could say "well those kids are dumb, they're expected to do bad." But the counter to that is, "they can do much better than they're doing," and the science would support it.

There are many biological and geological processes that remove CO2 from the atmosphere. Many of which could be sped up.

Care to elaborate on what you mean? Surely you don’t consider all IT and Infrastructure employees to be “non-technical”.
There is a moral hazard here, but the reality is that we’ve passed the point where emissions reductions alone can get us where we want to be. We will need both reductions and removal.
> 0xA000 started out as an experiment in trying to create a pixel font with greyscale squares for anti-aliasing.

What does that mean? Aren't all fonts using grey pixels for AA while pixels are, well, squares (or close enough)? I know about "sub-pixel AA" done using colors but I don't think they're referring to this.

Or do they mean that the font has no AA at all and is just one using regular pixels, all of the same colors? (FWIW I'm using a version of the Terminus font that does just that: "pixel perfect" rendering at several sizes, no AA)
Well it probably is...

Yes. Nothing stresses me out more than talking to other people. Going on an hour long walk by myself (hopefully in a nature setting) is what I need. But when I work in an office there is a stigma against just getting up and walking away for awhile. Butts in seats. This is one of the reasons I love working from home. My mental health has improved infinity fold since starting to work from home.

It's more plausible to me when you think about centralization vs decentralization.

Sure, it would clearly be cheaper to emit less if the emissions were mostly coming from a small number of controlled facilities.
But when the sources are millions of tailpipes and smokestacks across the globe, it's at least plausible that a centralized, new recapture solution would be cheaper than decreasing emissions in millions of old places.
Yeah, this is something I'm considering still. I've heard from a few users that they don't like the pieces being rotated at all, and some would rather have click-to-rotate to make it more difficult.

I might have to make this an option, but waiting to hear from more users on this before deciding.
For a long time I wanted to create a daily dev journal, but really wanted something super low friction. At one point I was just using markdown and putting in a git repo, but the process of saving was tedious. I was able to quickly import all the markdown files into Notion, and aside from giving each entry a title that has little semantic value, it's met and exceeded all my expectations.
