> Even without proof of stake, it's possible to make transactions low-cost.

only at the cost of reversibility.

the central thesis of proof of work is that an attacker must expend more energy than the "main" chain, across the duration of time they want to be able to reverse a transaction (older transactions require more time).

The amount of energy expended is determined by mining rewards - over time, mining profit will converge to zero, miners will expend however much energy the mining rewards buy.

as such - any reduction in energy expenditure (i.e. a reduction in mining rewards) will lead to a reduction in security, making it easier to reverse transactions.
Signing attestation by itself wouldn’t work because of double spending. You would need either a centralised database of who owns what or a blockchain.

If you google search every title of the contents you will find 10 stackoverflow pages with answers for each of them. Source: I've done all of that. The author didn't try to describe hard things, like, say, how to do distributed encoding of a single video. etc.
Can you elaborate on how you'd use update/delete?

It sounds like you might be able to do that using range partitioning instead, similar to the example in the blog post. Then just delete entire partitions when they are older than x days.
So, you could quite easily cause someone to be stuck in a time loop, if they didn't know about the meta-time nature of things.... interesting!

Step 1 - Allow random users to dump random files onto your website.

Step 2 - Random users dump random files on your website.

Step 3 - Create an outrage, OMG, OMG!!! Google killed my site!!!

Step 4 - Post on HN, generate more outrage and sympathy

Step 5 - When the real thing comes to light, oh yeah, I did allow random users to upload random files to my website. Let me write a blog and tell what lessons I learned and still claim "How Google killed my site".

Step 6 - Kachinnng, look at all the attention and internet points me and my website earned!!!

We had a similar episode where this guy https://news.ycombinator.com/user?id=dcurtis created an uproar and outrage about Apple only to be proven[1] that he was the one at fault and not Apple. Now that the reality came to light, he's no where to be seen, not even an apology. We'll see him back during his next episode of outrage and attention seeking.

ECC (curve 25519) would be preferable.
Incarceration rate is an invalid indicator. You need to look at the crime rate, the release rate, and the rehabilitation rate.

There are cycles of poverty and culture causing this but the government’s actions turn SF into both a honeypot and an accelerant for crime. It does this by turning a blind eye to crime both in talk and action.

Criminals know that SF is a great place to commit crime. This draws them in from all over and they commit more crime.

The DA is selling the narrative of rehabilitation but the criminals are just taking advantage of it to just commit more crime.

Typically you'll need to work 30 hours per week to get health insurance. That is 75% of the 40-hour week. Assuming you do that, and not treating holidays as anything special, here are the numbers:

You're seeking $66.67 per hour. It's $104354.29 per year. (75% of $139139.05 per year)

That seems a bit high for a front-end developer unless you stay in the SF Bay Area.
Same for me. Extending an internal API with simple queries took me half a day to get my mind around to. Learning about a warehouse system with a bazillion schemas, toggles and cogs and endless conditionals can while a few days of mine and I came out feeling happy and content, and wanted to do more, nonstop.
I've been looking into those Avago/Broadcom dot matrix displays recently. I don't think it'd be too hard to recreate something similar with tiny SMD LEDs on a PCB and a slightly intelligent driver board, for much cheaper. Would there be a market for something like that?
That is too cold a temperature for a hot and humid climate. If you don't believe the flesh saying this, then consider that it invites condensation and costs far more to maintain that temperature than it's worth.
I’m a bit late to the party on this but the article fundamentally misunderstands DDD. DDD explicitly doesn’t concern itself with implementation details. It doesn’t have an opinion on DB servers, how you should partition data, etc.

DDD is a way of modelling your business logic. Your domain doesn’t care about databases or servers, these are details at the edges of your application.

If your domain does need to care about the details of how it runs on servers and databases, then perhaps DDD is not the right tool for the job.
> But with something like CryptoPunks you're essentially paying for digital beanie babies, which are worse than real ones since anyone can display and enjoy the image you paid for.

It seems like the obvious counterpoint is that perhaps all of these “collectible” scarce physical things which are bought and sold for huge amounts of money (art, coins, relics, etc.) are in fact being used simply as a way to identify a unique “token” that is good for generating hype among a group of people and exchanging value among that group because it has a story attached to it and isn’t easily counterfeitable. It’s pretty obvious that a decent reproduction of most of these things would deliver the raw surface aesthetic experience to the vast majority of interested people and would cost much less. For many famous paintings it’s easy to understand why someone would want a reproduction in their house for decoration. It’s less obvious to me why someone would want a reproduction of an old coin with a minting flaw, but perhaps that’s just me.

I tend to agree. It's difficult to draw a good shell around what I call myself. Yes, there is the body, the brain, some part there somewhere that is "Me", but I also have children, and ideas that are part of my identity.

I tend to draw the border of self a little looser than most. I'm a human, a living being, and a piece of me extends both forward and backward in time far beyond the start and end of this meat bag at a keyboard.

> Do triangles exist? Is the definition of triangle "bereft of any definition that can be objectively measured"?

Certainly not, the definition of a triangle is quite a rigorously defined mathematical construct.

> Is the Ship of Theseus fundamentally different than a triangle, or is it merely a difference of degree?

It is not a difference of quantity but quality. A triangle is an objectively defined, mathematical concept; identities are as I said “You know it when you see it, and different men see it differently.”. — you will not find many mathematicians disagreeing on what is, and is not a triangle.

Another fundamental difference is that a triangle is an abstract reasoning tool, not an empirical one, and no mathematician would suggest that real life objects are, or are not, triangles.

> Ask any random human to define some extremely complex mathematical entity, and you'll get various fuzzy answers.

A lay human being with no mathematical understanding perhaps, but all of these entities have been defined rigorously in mathematical terms.

> Does that mean complex math doesn't really exist?

You were the one who speaks in such terms as “existence”. I will not have you put words in my mouth.

All I said is that one has an objective, rigorous definition such that you will find that every single educated man in the field agrees on what is, and what is not a triangle, such that a machine proof assistant can be fed this definition, and verify machine-level proofs that reason about them, and that the other lacks this such that you find that nigh any man, expert or not, has a different definition of what constitutes the identity of a physical object, and where a new object starts.

Not many care about monopolies. We care and want fair competition. Each of the companies mentioned in your comment don't matter except where they are anticompetitive (FB is based on what Mark says alone and Amazon appears to be based on their Amazon basics and similar patterns, as I recall Apple has right to repair related issues tangent to this and Google and Apple colluded on fixing salaries, not sure about the details here...). None of this has to do with monopolies.

Im not a hacker of networks, but I had to learn how stuff words when I had a pirate bay chatroom manager go to reddit and other places and do as much slandering as he/she could.
I still dont know what he /she did that against me?
Im even politically kinda on their side. So it baffled and still baffles me why so much personal hate against me. I now discover that entire internet relay chat, and hacktivist cultures online, are blindly on pirate bay side, because they dont use their own judgements as independent humans (independent of the need to have a leader or a superstar to follow...). Its sad that intelligent people cannot keep a neutral ground for themselves and even judge their own friends from a neutral perpective. I have been severely harassed by a pirate bay admin and still I dont hate the pirate bay, I try to investigate what made the manager of the pirate bay today harass me with such devotion. But then I see that people who follow the pirate bay mindsets and politics aren't exactly free thinking individuals. They come from the extreme-leftist political area where violence is JUSTIFIED always if its used against ''the enemies''. And im their enemy apparently. Im not even a fuc...cen journo lady.Im a NOBODY.
> Uber really shines in countries with a culture of haggling and gouging tourists.

> It’s the ultimate travel “screw remover”.

So why do you think this is? Are you aware that western capitalist firms fuck/screw these countries up, before their citizens fuck (with) us? [1] [2]

Their dishonesty is based on having to survive to survive this original (and ongoing) exploitation.

Do you really look at the global south and not see this?

I'm not saying Uber doesn't help serve as an attempt at a digital system that helps sustain reputation (although it is one that can grossly exploit the driver). [3]

Sure, but Wordpress is still running PHP files for every page load and back-end query. Dolt would help offload some of the code’s complexity, but that would still leave a significant attack surface area.

In other words, by itself Dolt couldn’t solve the problem of Wordpress not being run mostly from static assets on a server (plus an API).

Fiction drives home unrealistic standards or extremes.

I found the data to be dubious ofcourse. Just like we can extrapolate all sorts of nonsense from data - movies aabout relationships might not mean anything at all.

Considering that life is 90% boring routine and fiction does not show or truly represent that boringness in order to sell the story. They need drama. Thats why writers wont write about a perfectly normal day with a couple talking about tiles for an hour dialog near the kitchen sink.
Ask HN: Mobile-first” databases that sync to a central server?
I keep hitting the following problem over & over again:

- Build a mobile app (mostly some sort of CRM/ERP kind of app), where ALL the features need to work offline
- This means that all the data (for the currently logged-in user) needs to reside on the mobile device.
- This also means that any CRUD operation needs to hit the local data-store first, and should be synced in the background with a remote data-store.
- This also means that if the user signs into another mobile device, a relevant subset of the remote datastore should be "restored" on the mobile device.
- Probably a few other subtleties that I haven't thought through yet.

Is there any stable/production-grade DB that solves this problem? Bonus points if it's an RDBMS, because building reports for a CRM/ERP is 10x easier on top of an RDBMS vs a document/JSON DB.

Many of the author's points are worth consideration (especially regarding use of 7-segment displays for anything other than digits), but come on:

> A bespoke display panel was used; itwould have been safer, easier to read, more versatile, andcheaper had a hi-res display been used

Obviously the author has never actually tried to design a product both ways. Displays are expensive, and I'm not just talking about the panel itself. Usually you must go up a level or two on your processor hierarchy: a 7-segment display or matrix can be driven by a 4-bit microcontroller. A VGA-resolution display will require a high-end microcontroller, usually a 32-bit Cortex-M3 or M4 these days. A true "hi-res" display, which has admittedly drifted up in quality since the author wrote this, will push you into application processor (i.MX) territory.

That may not sound like much, but typical costs for those levels including supporting circuitry are in the neighborhood of $1, $10, and $100. This is because the tiny microcontroller needs nothing; the fancy apps processor needs DDR SDRAM, NAND flash, a PMIC, and is probably a BGA you have to route on an 8-layer board, with GHz MIPI signalling flying around, and don't even get me started on the software complexity.... You can do all of these things, and if it genuinely makes your product better, you should. But do not pay the cost if your product does not benefit.

A coworker of mine likes to tell a story about cutting the sales price of a medical device from $5,000 to $500. The main source of that savings would have been removing the display. (Yes, really. Medical displays are expensive.) This was rejected by product management, on the reason that "The people who buy this stuff are not the people who use it. The people who buy it like shiny-looking things. It is much easier to sell a product that looks complicated and expensive to a procurement officer than one that looks simple and possibly less advanced, even if they are the same inside. That display does do something -- it sells units."

In operation, the display had a bunch of whiz-bang crap that could have been deleted with no consequence, and two touch buttons for "arm" and "stop". Of course, you had to use a physical button to actually activate it; IEC 60601 wouldn't allow using just a touchscreen to start or stop a medical procedure! So the display really didn't do anything functional....

So, no, high-res displays are not always the answer. Think carefully about the cost!

What?
I’m gonna have to disagree here. The average coffee cup is 118ml and the average tea packet contains 1.5-2g of tea (from a quick google.) When I make morning tea I use a packet for 1 coffee cup of hot water, so that’s basically the standard. It is very drinkable, as I do it every morning. Any more water and it starts to taste like water as opposed to tea.
Is there anything like this for coffee?

Why would owning the NFT give you any rights over the goods? If I've understood correctly, you just own a token. It has no inherent value by itself anf you basically own a link to something.
Key quote for me:

> The trap, then, is that creators can get hooked on creating these. Buyers with a sunk cost get hooked on making the prices go up, unable to walk away. And so creators and buyers are then hooked in a cycle, with all of us up paying the lifetime of costs associated with an unregulated system that consumes vast amounts of precious energy for no other purpose than to create some scarce digital tokens.

Tangentially, this resembled me of troubled financial markets (minus energy expenditure). Companies are hooked on making their stock go up, even if it requires distorting reality to hide fundamental problems. Like creators who become more about NFTs and their value than art, companies become more concerned with inflating valuations than actual business. Stock buyers are hooked on making stocks go up, not selling even if fundamental indicators are suffering to the point where viability of the business should be in question. Banks are hooked on making stocks go up… A vicious circle all around.
Only if you can get them listed at Digi-Key/Mouser/etc. Even if it's under a "maker" brand like Adafruit, Sparkfun, etc. Anyone who can replacement TIL311 and friends displays in there, and advertise them, will sell quite a few.

They're not hard to make, but they're the sort of thing that no one really wants to make in-house, since they're a means to an end rather than an end in themselves. Great thing to sell, though!

It sounds like brewing tea in this way at home would be a misunderstanding of the standard:

> This standard is not meant to define the proper method for brewing tea intended for general consumption, but rather to document a tea brewing procedure where meaningful sensory comparisons can be made. An example of such a test would be a taste-test to establish which blend of teas to choose for a particular brand or basic label in order to maintain a consistent tasting brewed drink from harvest to harvest.

On the other hand, it's very strange to me that the type of tea is not specified. Pouring boiling water over anything other than black tea typically destroys the aroma completely, and green tea in particular turns bitter and extremely taninnous. Also, 6 minutes of infusion sounds extreme for green or oolong or white tea.

For green tea, the nicest taste I've gotten by far is from very short brews with medium temperature (~80C) water with large quantities of tea, drinking 2-4 infusions from the same leaves. I've never measured the quantity in grams, but after the tea expands, it would typically fill the brewing pot.
