The point isn’t which startups to found, it’s how to find a startup idea if you don’t have one or aren’t sure if your idea is good.

People who are building what they want to see in the world don’t need this article and would likely not even read it. This is for the “entrepreneur as a lifestyle” folks who want more to be entrepreneurs than they want to see a better world.

These people are trying to maximize the chances they’re going to get to keep being entrepreneurs, which is a wholly different problem than what you’re talking about.
> Let's not even mention the fact they charge as much as some PC's just for some more RAM.

It's really just market segmentation. A charitable way to think about it is that it lets the wealthy (who will buy Apple products with the best specs) somewhat subsidize less wealthy people buying Apple products on the lower end of the scale.

If they didn't do this, their profit margins would be flat across the product line, which would price some people out of Apple products while leaving some potential profit on the floor for richer users who would have still bought it at a higher price.

Whether this is a morally good practice overall or not is debatable, of course.

The system does not care for their well being because they are redundant. Drug use was frowned upon during the Cold War because we needed people to win a industrial war against a much bigger enemy. We don't need them anymore, so the system does not care if they end overdosing in an alleyway. It is all connected, culture, social and economical.
I don't love the fact that everything is being watched and analyzed, but it's actions taken based on that data gathering that I'm worried about

Of course we understand that the only reason to watch and analyze all of this data is to be able to take actions based on it

I am definitely in favor of preventing the gathering to guarantee preventing the actions. No one should trust that data is being collected without any intention of using it.

Sorta yes, but mostly no.

You can absolutely just sit down, read the classics, and then read discussions of them. You can gather ideas, and it's not impossible that you could get your own thoughts published.

However, you'll miss a lot of the point. The classics aren't a set of facts you can memorize and apply, the way you can with programming or the hard sciences. They're a set of world-views, different from your own and from other people. Even when you bring your own world view to it, even by reading what other people have thought of it, you'll still miss that dialectic. You'll miss the skill of listening and challenging your own ideas.

It would be a bit like trying to learn to dance from reading books. You can, but you really can't. You need the eye of somebody experienced to tell you what you can't see or feel for yourself because you have only your own perspective.

You can easily find yourself a book group or other discussion forum. Ideally, it would be more than just casual readers, but people who were dedicated to the domain you're studying. That might be bulletin boards or listservs or other places where scholars gather. If you're not challenging yourself against the specialists, you're going to miss out on a lot of the real insights.

Ultimately, there's no real substitute for the liberal arts education process, where you work with other students, guided by an instructor. Personally, I like the idea of Signum University, which is working on taking that idea as seriously as a brick-and-mortar college but entirely online. It's much, much cheaper, and presents the opportunity to do real scholarship.
Ask HN: Does there exist a read-optimized distributed K-V store?
I have a large-ish (right now ~billions of keys, ~100TB) immutable/append-only dataset, with rare inserts (~1GB chunks, once every few minutes) done only by background bulk insert, and no need for any kind of consistency (i.e. inserted data isn't "from" users, and so nobody is expecting inserted data to be reflected immediately; and keys inserted together don't even need to become visible atomically, as clients will retry to fetch dependent keys.)

And I need to serve huge numbers (~trillions) of single-key point queries out of this dataset, out to many consumers over the Internet, with each fetch having as little per-fetch read latency as possible — ideally, with round-trip times resembling e.g. a Redis GET.

Basically, I want the performance properties that you'd get in a single-node scenario from using LMDB and dedicating all your RAM to OS disk cache — but "in the large", with data being sharded into vnodes and then those vnodes being spread+replicated across an elastically auto-scaled set of compute replicas.

You'd think the answer would be a thing that calls itself something like a "distributed KV store", "serverless NoSQL store", etc.

But it seems that all the big "distributed KV store" products and services — DynamoDB, BigTable, Cassandra, Riak KV, FoundationDB, CockroachDB, ScyllaDB, etc. — are all built to optimize for write throughput in a many-distributed-writers use-case, with little concern for per-read latency. They're all "LevelDB in the large", not "LMDB in the large."

Does HN know of any system that would suit my use-case? Or, if not, any ideas why nobody has built one?

If you’re passionate about something doesn’t the problem come naturally?

It seems to me this ideation thing seems unique to people who are stuck in the ideology of “I just want to be a growth entrepreneur in startups”.

The world does not NEED startups, or entrepreneurs, or exponential growth software startups.

People need solutions to their problems, and there are very many worthy problems that will never generate exponential growth or billion dollar valuations - but the current startup culture ignores these.

I agree that government records should be open and are good for transparency. The problem comes when people don't realize that something they're doing would put all of the personal information they've submitted into the public record, or when it's required to do this to access a service.

In Washington, and Seattle specifically, doing something as simple as reserving a park space or signing up for a constituent newsletter means a public record has been created. Data brokers and people who want to "just reach out for a simple conversation" and political parties routinely make grabs for this data to populate mailing lists and the like.

That's annoying and shouldn't be a function of public records laws. We exempt utility billing records, even when the utility is owned by a city, and library card data and so on. Asking for a service from the government should be wholly exempt.
Unfortunately we also agreed to have dmca.

Calling companies that hold a patent you find valuable and aren't distributing it's use how you personally see fit a "patent troll" isn't just inaccurate, it's an intentional mischaracterization for the purpose of eliciting a negative emotional response solely to spread your narrative. It cheapens the meaning and lowers any engagement to fight for the same cause when you realize it's a facade driven entirely by sour grapes and a lack of understanding of the patent system being criticized.

I guess it's okay here though, because [passionate story about side project idea using eink that could be tinkered on but never actually idealized into something].

In practice they generally were semi-optional, because title-less posts were somewhat common, particularly on Tumblr (which always straddled the worlds of "proper" blogging software and twitter-type things a little uncomfortably); how gracefully readers dealt with this varied.

Not sure on that, but I am in favor of replacing the horrible current billboards utilizing LEDs. So much light pollution, and a imo adds another distraction from focusing on the road.

Ironically: US EPA Cafe standards drive the increasing vehicle size.

https://www.meche.engineering.cmu.edu/_files/images/research...

The cheapest way to meet the EPA MPG requirements is to INCREASE the vehicle wheelbase and make it larger. This is much easier than making it lighter or adding fuel efficient engines and technology. Plus, Americans have shown a preference for larger cars.

It's a win-win until people can't afford the tin

Back in 2019, RISC-V was 15-20% smaller than x86 (up to 85% smaller in some cases) and was 20-30% smaller than ARM64 (up to 50% smaller in some cases).

https://project-archive.inf.ed.ac.uk/ug4/20191424/ug4_proj.p...

Since then, RISC-V has added a bunch more instructions that ARM/x86 already had which has made RISC-V even smaller relative to them.

I think it's a little weird to assume that's how everything is "supposed" to be just because that's how it's been. There's really no "supposed to"; there's what there is, and what we can do and change and build.

I do agree that some people take this to far: worrying so much about death that they forget to enjoy life, pouring their lives into life-extension measures and leaving precious little time to live. (Then again, the people who pour their lives into life-extension could end up benefiting countless others; how's that for big-picture thinking?) But I'd hardly call it a "tragedy" that humans want to live longer (or even forever).

I don't particularly fear death, I don't think (at least not any more than your average human), but I am supremely bummed out that (assuming humanity doesn't destroy itself first) I'm going to miss out on things like advanced spaceflight, viable long-term colonization of other planets and moons in our solar system, and -- if we can figure out that pesky speed of light issue -- travel to and colonization of other solar systems. And that's without getting into more "out there" stuff like mind uploading and catoms and whatnot. Humanity has so much potential, and we're still a childishly young species that has so much room to grow. To me, the tragedy is that I won't get to see what happens with all that.

I think the bottom line is that we should stop judging people for how they use their time. I'm sure there are some people who would scoff at some of the things you or I do with our time; who are we to criticize someone for working to lengthen the human lifespan?
That only works if the cup and donut have the same area.
I'm sure the fashion cabal as you say is able to come with a bunch of different looks every 6 months. Of course everyone is more or less sensitive to these stuff, but overall it works extremely well (and if like me, you think "this stuff doesn't work at all in me, I don't give a shit about clothes", be sure that someone in the cabal have thought of you and decided what people who don't give a shit would wear too)
As a devops / platform guy, I would have typically made something like this by gluing a bunch of cloud / data tools together. e.g. like an ETL tool, orchestrator tool, maybe some process that dumps a DB, run a custom script, etc.

After working with extensions more, I really feel like some of these postgres-internal options should be assessed instead of always defaulting to the cloud tools or custom scripting stuff. In a lot of cases, it's way easier and cheaper to just use an extension, and there's really no big risk since it's just using the extension for an ETL job basically.
I have made a few RISC-V cores for FPGAs personally, and I would say that the C extensions are 100% not worth your time to implement unless you need absolutely minimum RAM size.

The most interesting part of this story is the potential legal risk of holding onto the records that were improperly disclosed.

Had the author not notified the city that they had royally screwed up by divulging far more sensitive information than they had realized, they likely would have never realized the error, and he would have been free to do whatever he liked with the data.

But once he notified them of their error, and they realized that the data was now in the hands of someone who should not have been given access to it, there is an interesting legal question about whether he has the right to keep it.

If this were physical property, or money, then there is a lot of case law around what happens when you find yourself in possession of something that was given to you by what was clearly a mistake. If a car dealer accidentally drops off a new car at your address, but later realizes it was intended for another address, you don't get to keep the car. Likewise, if $100,000 shows up in your bank account because it was mistakenly deposited there, that's gonna get clawed back.

But what about data? Mere information? I think there is a pretty good legal argument that there are categories of data (e.g. trade secrets) that a person can be ordered not to possess. So I think the author made the right call by agreeing to cooperate with the city's request, even if it was the city's own colossal error that put him in that position.

Nevertheless, it would have been nice for the city to reward him for his bringing the issue to their attention, rather than immediately trying to threaten him if they didn't help clean up their mess.
> I would rather doctors hedged their advice/proclamations a bit, then to be definitive when they shouldn't be.

Medicine, like science, is based on available data. I have no problem with them admitting they were wrong based on new data.
I don't really disagree with any of your points either.

> one trick ponies are the order of the day. So that would mean shedding staff, which looks bad

What I think I'm arguing is that most companies really don't need dedicated full-time staff in that way. Agency models work well in many industries that are built around one-trick ponies, which I'm arguing is what most development really is.

In those industries there really isn't a negative connotation to ending a project, shipping it, saying goodbye and thanks for the hard work to the team who did it. If they did a good job and the activity was successful, many of them will likely be hired back for the next job anyways.
Linux phones have a different threat model. Saying they lack any form of security implies you know nothing about them: https://source.puri.sm/Librem5/community-wiki/-/wikis/Freque...
I like to think through example use cases from the perspective of the assumed customer segment.

From your example: I am from a vulnerable group and I am uncomfortable handing over my phone to authorities. If I am uncomfortable with handing over my phone, why would I digitize my license where I would then be forced to do so? If I was looking for an alternative solution to this problem, it would need to be more convenient than just carrying my existing ID, since the whole advantage of digitizing my ID is so that I don't have to risk losing it. If I have to carry a separate device, that advantage is lost.

Also I would actually talk to the people in the vulnerable groups to validate these assumptions before getting too invested in the narratives. They may not be as concerned as you think or may not have considered the risks.
Finally, a power button! Talk about burying the lede. That's a big improvement for most casual users. Yes, you've been able to use a GPIO pin, a momentary switch, and a special daemon, but this works out of the box.

Most businesses need to buy their raw materials to produce their products. With Meta, the raw material is consumer data, which users have been giving away to Meta freely.

This brings me right back to June of 2009, as the markets started to spoil and the derivative markets fells to shambles. A few hapless souls in Baltimore would be tasked with manning 2 standing 12 hour shifts for as many weeks as it would take to properly reconcile what could only be described as a tsunami of unreconciled data for a single large custody player in the sub-prime markets. It took about 4 months, and went through several phases of rebalance but we got it done. As I look across the landscape of LLM, the word "context" screams back at me. I think the processing power involved to make all the poor choices necessary to find the right choices and wonder how that could've been done without a teams of people thinking about the same problem from many perspectives.

I'm perfectly fine with the git CLI and IntellJ for local review work, and Gitlab web UI for the communicative part of a code review.

Only thing I agree with is, I (sometimes) hate the three-way unified diff in IntelliJ for merge/rebase conflicts.
Other times (harmless conflicts), I love it over using the CLI.

Personally, I found the example for the desired diff format confusing.

I prefer split to unified diffs though.
