Bitcoin nodes only need to work with the state of existing spendable coins.

The need to track previously used stuff in some other systems to prevent transaction replay is a design flaw that Bitcoin avoided.

The vast majority of the blockchain data is digital signatures which you don't need anymore once you've validated them (except to help other people sync up).

I see, interesting point. Thank you :)
All the nodes (even the old ones) run on the rule that the longest chain (the one with more work) is the valid one so the chain with the one invalid block won’t be longest because no one will build on it. As a result even the old nodes which don’t know the new rules won’t accept the blocks based on the longest chain rule.
Leaked Documents Confirm Second Iranian State-Sponsored Ransomware Operation
Not a Dane; 1% is very low compared to where I am, which is about 2.7% for 20 year. Is that subsidized by the government at all or just a different market?
Death rate is calculated as deaths per billion miles driven, so I don't see how the respective populations matter here. One could make the argument that population density is important to consider, but in the US the less populated states have higher death rates IIRC.
Yes, I think the implication is that there's some sort of weird, inconsistent behavior. (Which is consistent with something like voltage transients that are mentioned in the article.)

My mom died of lung cancer (actually brain cancer which often is the end result) but never smoked; however her father smoked all his life, and my dad smoked for decades before quitting. We never did figure out where the original cancer came from. End stage lung/brain cancer is a terrible way to go, which is why I have zero idea why anyone smokes at all.
Automation implies boosting productivity. Who gets to keep the surplus (profit)?

During New Deal and Great Society, Capital shared that surplus with Labor. Since the mid 1970s, not so much.

Instead of automating, we could simply eliminate huge swathes of work. Squint a bit, and all the bureaucratic burden (bullshit jobs) just look like very complicated rent seeking.
I'm not sure it would be so easy to find a fifty-year-old who had been in the Tiananmen Square protests and who was playing WOW or Starcraft, but fair enough.

My post explicitly said that Clubhouse's combination of existing technology is what makes it unique - voice chat, topic/person discovery, search. All of those things are possible through other mash-ups of existing technology. Hell, you could conceivably clone Clubhouse with a Minecraft server and Discord.

But CH has the overall experience that reduces friction. And now it also has network effects, since enough interesting people are on it that the experience is just that much better.

I, likewise, share the concern that the CCP will use its heavy hand to destroy CH. I hope the founders are smart enough to divest from CCP-controlled tech ASAP.
Where in my comment did you read the word subsidies? I was talking about the idea of internalizing "external costs" which I think is impractical and also somewhat impossible because at least some external costs do not occur at the point of production but at the point of consumption.

edit: Now I get it. You must have misunderstood my point. Let me reiterate. Health care cost are part of the external costs of food. But they occur non-linearly, based on the amount of consumption. But they can only be priced linearly. So someone who eats a little meat would effectively pay the external costs of someone who eats a lot of meat.
Jeff Bezos will testify in front of congress that he will cease to be innovative if required to pay taxes.
My great grand mother died from lung cancer and never smoked one cigarette in her life. She was a humble and very sober woman. (no alcohol, no tobacco or drugs, just her medication). The reason, why she died of lung cancer is, that the area, where she grow up, was near coal mine & chemistry plant. LVL 89 tho, nice age anyways. RIP Grandma.
On the other hand, my neighbor from the rural area, where my mother was born & raised, lived all the way up to LVL 93. He had one shot of hard liquor every day and smoked exactly 3 cigarettes a day. His calm live and routines granted him a superior lifespan. He died from age, calmly in the bed, with relative good health for his level.

That in group includes mainstream media journalists who report on it and influential people who read it and make decisions based on it. I can't believe you're making that argument with a straight face. We just had the Twitter president (who's been kneecapped by the Twitter ban, if you need another example of its power).

And sometimes you just screw your product up by not listening to what customers need, or by assuming that you know it better than them.
For now i refused to do custom branches, instead the product is made more and more configurable. And it's more successful approach so far than trying to maintain a separate version for every customer.
We could have a tax on documents which are non-public.

For example, the tax could be 1 cent per page per day which is non-public.

It would apply to source code, images, or anything else that might be reasonably printed on a page.

Then companies could pay the government to keep their employees work secret, or publish it.

It should help innovation as far more work done by humans gets made available for others to build from.
Startups have a duty to their shareholders to make money, whereas Bitcoin has at least a nominal duty to its inventor[0] and its whitepaper.

I don't make judgements on whether a global phenomenon is "stupid" or not, because frankly I think doing so is stupid itself. If everybody goes in a stupid direction, you can pretend it doesn't matter, but you'll be wrong.

Just because it isn't important and profound to you personally doesn't mean it's stupid. Whatever you mean by that word anyway.
It would indeed offer no security if the hashes weren't signed (which they are).

The question is rather why distribute a separate file with hashes and their signatures, rather than just the signatures themselves, seeing how all useful cryptographic signatures contains the hash anyway?

I suspect the answer is that it is somehow more convenient for the build and release process to distribute one file with all hashes, rather than lots of individual signatures for each artifact. The release process is quite elaborate with several parties independently reproducing that exact build. But someone would have to correct me on that.

That's probably also why they don't consider the broken Windows certificate important enough to stall the release. Relying on a single CA does not provide them with the type of security they are looking for.
Ask HN: Why is there no adopted standard for web scraping?
I feel many sites benefit from scraping, or are happy to allow it within certain bounds. My question is why have no standards emerged around how data is structured and accessed for web scraping?

I am aware of standards such as Open Graph - is this the closest we have gotten to a standard of machine accessible data on the web?

yep, the thematic entries are nothing like cryptics; the only similarity is that they both involve wordplay. the wordplay here is closer to jokes like "what fruit wanted to conquer the world?" "alexander the grape!" - that is, while the answer will not be a real word or phrase as would be required in a cryptic, it will be logically derivable from the theme and the clue.

one interesting thing about the non-thematic entries in an american crossword is that the only form of wordplay they allow is what in cryptic parlance would be called a "cryptic definition", that is, a clue which is a straight definition in which the words need to be read laterally. the nyt cryptic definitions are as good as any i've seen in the guardian, particularly my all-time favourite,

For this specifically, Musk was so immature and inexperienced that he was either kept away or removed from higher posts, but since the ideas themselves materialized and were successful (see Zip2. X dot com), he walked away with millions. He was the definition of failing upwards. And once you have 200 bars of walkaway money, it's really, really hard to fail.

Per Wikipedia: "Within the merged company [PayPal], Musk returned as CEO. Musk's preference for Microsoft software over Linux created a rift in the company and caused Thiel to resign. Due to resulting technological issues and lack of a cohesive business model, the board ousted Musk and replaced him with Thiel in September 2000."
I agree but there's one practical problem with this: other markets (e.g. the EU) need to nationalize or reproduce it too or else the US is getting significant geopolitical leverage.
Chains like McDonald's do in fact waste large quantities of food (in absolute terms). I think this is largely caused by the even larger quantities they sell. But to a certain degree it is down to completely artificial and arguably pointless metrics:

1. They produce (or used to, this practice has been removed in Germany, I think) a large amount of food on stock and kept it warm. If it isn't sold after a few minutes (15?) it gets trashed. This is to optimize the speed of sales.

2. They hand out bizarrely large quantities (especially soft drinks, but also cheap stuff like fries) that often the customer won't eat completely. This is for a reason that I don't understand. Might be a US thing, though.

>"Browsers... "fast", with great results."

Are you joking?

I have seen progressively worse performance from even the best browsers, and page load times that should be instant often literally take minutes or never load unless I completely kill the browser process and return. The slowdown is nearly inexorable, with occasional improvements in some versions before resuming the dismal trend.

Simple word processing and spreadsheets are so laggy on keystrokes as to be almost unusable, and by unusable, unresponsive on a level hundreds of times worse than DECADES ago, on computers orders of magnitude less powerful. Simple cursor movements are so laggy that I must set aside my train of thought to attend to the tool.

And this is on a very solid CAD-level computer, FIOS connection, etc.

It is disgusting and unforgivable. I quit software career 15 years ago for a new industry in no small part because I saw this trend of ever more complex "tools" & "frameworks", etc. creating a situation of building castles on shifting sands, with serious declines in the ability to reason about debugging, performance, or security. It is only worse now, probably exponentially. Worse yet, it seems to have yielded no perceptable "programmer productivity".

It is one thing to architect and program to take advantage of upcoming advances in hardware. It is quite another thing to ignore it and assume that the hardware builders will save you from the bloatware that you foist on the world without a serious thought.

But that is cross-language, which is not ideal but not an internal problem if you work in one code base. (O)Caml also has `let` and is quite a bit older than JS.
I have a Maytag washing machine & dryer from 1955 that still run and the only thing either ever needs is a new belt every 15 years or so.

I've seen the inside of modern washing machines and the difference between the two is stark.

Both machines are actually extremely simple, but the Maytag is incredibly overengineered. Every last component is quality.

Modern machines do everything in the PCB but every component had maximum cost squeezed out of it.

> ... that are focused on user privacy. ... Currently it only supports Chrome or Chromium

To me, that is an obvious contradiction.
I feel like making one more note. I said that “mutable references” was a misnomer and that it’s actually about unique references, but even that’s a bit of a misnomer, because it’s not quite about uniqueness, but uniqueness of access. You can have multiple &mut borrows to the same thing, but only one of them is accessible at any given time:

let mut x = 1;
let y = &mut x;
let z = &mut *y;
*z += 1;
*y += 1;
assert_eq!(x, 3);

z and y both point to x, but only one is accessible at any point in time. Touching y finishes the z borrow; if you swapped the increment lines, it wouldn’t compile.

My memory is fuzzy (this was quite some years back), but I have a vague feeling that this lack of precision in the use of the word “unique” was a factor in some baulking at the proposed change. (“You’re trying to fix something that we admit is strictly wrong, but you’re not even making it right!”)
Likewise in Larnaca, Cyprus when when I was there 16 months ago.

Good for hobby or personal projects, but not if you’re building something for work. Many of these “free” tiers are designed to vendor lock you before they walk you off a pricing cliff.

Take Auth0. Free for up to 7,000 user but then it jumps to about $250/month. Migrating from Auth0 is a pain. You should really only consider these “free” services if you think you’ll always be in the free tier, and if you’d use the service even if it wasn’t free.
It’s often important that the BCC’d folk can see who the overt recipients were, though.

On the Cosmological Emptiness of Liberalism
I like having a window into the distant past because it's interesting. I don't see how that could be a bad thing. Sure, we should live in the present, but doing so isn't necessarily at odds with looking back. In fact, even if you're focusing on looking forward, you still need to consider the past and learn from it.
Oh, I remember that incident. Since then I've become suspicious of any translations from English to Polish.

I invent the toaster and sell the patent to Cuisinart. They decide not to produce it and sit on it for 15 years. Then the patent expires and anyone can make toasters. Now Cuisinart has lost out on growing a reputation for making toasters. That's their loss and the public benefits because they have toaster technology. And, the original inventor was rewarded and can go on to invent more things or inspire others to invest time in inventing because it pays off.
Yea, it accumulates in the food chain.
Ask HN: Basic Tools for a Small Company
I've been running a new company for a year now and it seems that the company is starting to take off. When running a company there are a set of basic tools that you will take in use and can't change easily afterwards. Some general considerations should also be ease of managing all the tools so that adding or removing user does not take whole day.

What basic tools does HN recommend?

Hosting email: I've been using Office 365 but I find unsatisfactory. The email service should be able to handle automated emails that I'm using to provide my service.

Simple task manager: I feel GitLab is a bit overkill. I would like to manage a few different teams.

File sharing: Once again, I'm using Office 365 but it is shitty service. Preferably I I would like to host some files in git (or git-like solution) if there would be tool with a simple enough user interface. Or should I start using Dropbox or some other dedicated service?

Messaging service: Is WhatsApp enough. Slack? Teams?
