In a sense that's definitely true. In another it seems to also depend on the cursive system. I recently went to Freud's museum and was able to read his letters without problems. Over a hundred years of using the same cursive system. It's beautiful, elegant and to a degree a form of art - Western calligraphy, if you will. The synergy of fine motor skills, art, history, neatness, self-expression and cultural transmission in conjunction with expressing yourself seem to be worth something. It's perhaps not even the cursive itself, but the training, persistence and effort that goes into creating something useful through your own hands that teaches so many valuable lessons. Easy is not always better - especially patience with oneself and persistent effort in mastering a skill could perhaps be beneficial for the next generation.

I can understand being able to discuss a complex issue over voice, but can you explain how this is possible?

> it is far easier to work through something even remotely complicated with voice instead of text

I find that this is the exact opposite. Trying to explain an error message (or have an error explained to me), or providing numbers, a name, an address, etc. is always a nightmare on the telephone.

"I'm sorry was that a 'e' or a 'z'?"

"Was that a 9 or a 5?"

Maybe it's just a bad phone connection where we can't hear each other properly. But even in the impossible crystal clear reception circumstances:

"What are you seeing right now?"

"Navigate to this address: http://<unnecessarily long url> "

"I talked to someone before and they said..."

"Please hold"

These are all limitations of the platform, or maybe limitations with how it's implemented.

How exactly are you able to work through 'complex issues' better through a phone?

> Chinese gets even more complicated being a language without an alphabet.

If I could be very pedantic for a moment...

Mandarin can be written in many alphabets. Almost every single native speaker one earth uses an alphabet to input chinese characters on computers and phones. And almost every native speaker learns their language using an alphabet - at least initially.

> If we weren't around, an American could demand a (significantly) higher wage.

This is exactly correct. I'm a US citizen and work at a high paying tech job. Amazon calls me at least once a month to try to convince me to work for them. The problem is that their highest allowed salary is lower than what I'm already making, and I also get gobs of stock bonuses worth at least as much as their stock bonuses. So they really aren't even trying to compete here. If they really wanted people of my caliber who were US citizens, they'd have to improve their compensation.
SpaceX got money from the US taxpayer. It wasn't a lot by the standard of rocket development, and Musk put in a lot of his own money, but SpaceX wouldn't have survived without the government. Elon Musk is very up front about that.

Boeing gets a lot of support from various levels of government as well. They get cushy tax deals at the state and local level. And what is a virtually-guaranteed military contract for cargo and tanker aircraft worth when you're developing a new air frame?

Uhhhhh, so this guys "brilliant" attack vector that he came up with was a 51% attack?

The same attack that is literally spelled out in the bitcoin whitepaper and has been known about from day one?

He didn't even add anything interesting on top of it. He just said "get 51% of miners, and then double spend".

Nor did he even discuss the ways of mitigating a 51% attack. If the network was being attacked, what I would do is wait for more than 6 Transactions to go on the network, before considering them "final".

In a worse case scenario of a sustained 51% attack, the users could simply change the Proof Of Work algorithm (which is a hard fork).

It wouldn't be 'great' but it allows the currency to survive. Now the government has to spend more and more money going on the attack.

Bitcoin works because of this economic game theory. Yes, it is possible to attack the network. This is well known. The reason why it doesn't happen is because attacking the network is EXPENSIVE, and can't last forever.
And probably why no one cares, especially when Unicode was limited to 16-bit.
Anyone can track Bitcoin transactions; That IS the blockchain. Undoing them will just result in a chain that they are still in the original wallets keys, you STILL cant steal them. And the window for doing this is likely an hour or 2 at tops, but still very unlikely.

An exchange might credit you on a few confirmed blocks, but after 6 (an hour) its pretty much confirmed, and any withdraws on the same chain will fail once the 51% attack is over.

You could move to Singapore, where a full-time (24x6) "domestic helper" costs about 400 USD per month. They'll cook meals for you, help care for your kids, buy groceries, do laundry, etc. Some people I know say they'd never move back to the US because of this.

For comparison, that cost is roughly 15-20% of typical rent.

I have an aunt and uncle who do this, but they aren't desperate, they're retired. They travel around the country, visiting places they'd like to see, and taking seasonal jobs as something to do and to help defray expenses. They still own their own house, but they choose not to live there, renting it out to their kids / their kid's friends. They've worked as lighthouse keepers, Amazon warehouse pickers, and as bookkeeping/maintenance for a sugar-beet picking operation (they're a little old for field work). Currently they're wintering over at the Grand Canyon while working at the general store in an rv park.

The point is not all of these nomads are forced into it by desperation or financial necessity; some of them just want to spend their retirement traveling and don't mind a little work along the way.

My aunt and uncle have a blog detailing their travels if anyone is interested: https://whatsnewell.blogspot.com/
Not really. A theory is useful if it makes accurate predictions and explains phenomena in the domain to which it applies.

Theories in physics has always been useful even though they are incomplete to this day.
That is a fair point. I don't know how to handle healthcare because it is a good with almost infinite demand (who doesn't want to live longer or be healthier), and a finite supply (of doctors, nurses and other folks who can provide services to help us live longer healthier lives). What happens when you have demand with limited supply?

Prices go up.

I don't think so. 'Language' per se is inherently abstract-symbolic and serial. Other types of thought rely on non-symbolic types of metaphor, often quite concrete ones, and on more graph-like connections between ideas. Sometimes the relationships between nodes are very fuzzy and inexplicit.

The best you'll get with 'language' is poetry and puns and outline-style hierarchies, but these don't cover anywhere near all types of thought. As stark examples, I don't think you can classify e.g. sculptures or textile patterns or mechanical designs as 'language'.
I don't know if he's using this as a proof of concept or if he actually plans on making a functioning city. If it's the latter, I doubt it'll succeed.

Ideas for "utopian" planned cities have existed for centuries (Like Walt Disney's original vision for Epcot) but they almost never get built. If they do, they end up being not much more than a novelty before becoming abandoned.
Would be great if he decides to forgo the capital appreciation, with a lease only policy. If this is successful, speculation in property is the disease we'd like to avoid.

Otherwise we'd get another property bubble and inflated costs soon enough.
I don't think anyone should have to live like this, and I'm not blaming anyone for being poor.

But I don't believe that purchasing, repairing, and fueling an RV so you can live paycheck to paycheck is easier or more affordable than sleeping on your (yes, possibly also poor) child's couch.

I get that there are people who are truly alone and have no other option - but the people with adult children seem to be indulging a stubborn desire to live independently, when what they should be doing is pooling resources.

I'm not saying it's right that there are people so poor that they have to live in multi-generational homes just to survive, but I also won't be shocked into sympathy for people trying to live like this when it's not their best available option.

I've seen plenty of older people refuse to move in with family when its time to, it always ends in disaster, and it's infuriating.

It wouldn't surprise me if a significant portion of these poor boomer nomads didn't actually have to live like this.

Fantastic. If someone can figure out a better way to implement the constantly dug up and paved infrastructure, early childhood education, and basic services of the modern economy (electricity, internet, water, sewer and maybe gas) that would help everyone in every city.
I would say Snapchat is more similar to Twitter than it is to Google or to Facebook. Question is, what is there to incentivize a user to stay on the platform for a couple extra of minutes? I personally have no clue why Snapchat the company is so large — does it really need that many engineers or marketers to maintain an app that is essentially a messenger? The failed Spectacles experiment just seems to scream that this is a company with a lot of money and no clue what to do with it.

Disagree. Master planned communities are nothing new. This is the same thing, just with some "celebrity" behind it and 21st century features. I expect to see more and more of this.
Odd that there's no mention of mass transit for a sustainable city, just a new freeway connecting it to Phoenix.

Perhaps you could inflict more mayhem by shutting down the miners under your control for two weeks, waiting for the difficulty to drop, and then undoing all transactions from the prior month.

The problem with Hiya as I understand it is that it is limited by CallKit list size. I'm not 100% sure of this, but I think Apple's implementation requires a fully offline call list so that your phone calls are not sent to a public server and could be logged. This means that the number of phone numbers that Hiya can call spam must be downloaded ahead of time and loaded into CallKit. What I see often is that a phone number will not be flagged as spam, but if I query the number through the app later, it will correctly show it as spam. Someone correct my if I am wrong, but I think this is the problem.
This might be a dumb question, but what’s the best way to actually use this to make a real application? I’m talking speak to a database and hook up a backend. I’ve enjoyed using vue from a “this is a neat way to make components” but I’ve never successfully been able to do anything with it. I understand it’s just the “view” and not a full MVC like rails but I want that to exist. I want it super opinionated and favor convention over configuration.

I haven’t found anything nice for a guide in building a real world application like this. Maybe it would involve multiple things vue + ? + Postgres or Mongo or some other option. But I want love something that would hold my hand start to finish connecting the dots.
You didn't steal them for you, you stole them for the original owner who tried to transfer them to the exchange.

In theory with 51% hashing power you could undo exchanges going back as long as you want, as long as you dedicated your entire hashing power to doing so from the point you are trying to revert to. You will get the longer chain so once you publish it it will take over. In practice I'm not sure if there are controls against very old forks from coming in and becoming the 'right one'.
No doubt. This example however, is low on the injustice scale, 87 people once and has been "described as a humanitarian gesture to save the lives of starving native people".
> the users could simply change the Proof Of Work algorithm

"Simply"? You're saying that an attacker having >51% hashing power on current system wouldn't benefit further from: a) user base splitting between forks (if block structure was changed), or b) all current ASICs dropping off the network (if the using method was changed).

> Now the government has to spend more and more money going on the attack.

They would have direct access to chip fabs and money to throw at it. Or just laws available to stop production (mining is illegal now).

Try to frame it in terms of $/user/mo over the next n months.

So $50k up front is ~$4K/mo for 1 year (or $5/user/month).

If you monetize, what would be your expected $/user/month? Your buyer certainly has some figure in mind already, and they're no-doubt low-balling you.

Is user growth rate positive or negative? What percentage growth have you seen MoM or YoY?

I would spend some time modeling the various scenarios to put the $50K into perspective. For example, if you plan on running this site for the next 5 years and you make $x/user/month and you have positive user growth (say 1% net user growth each year), etc.

I've always been infinitely curious about how Walt Disney's original vision for Epcot would've turned out. I'll be watching this with interest.
My exact same feeling. Even if the Han Character, as in the Han unification are the same, the glyph matters a lot in context.

It a little like replacing every french word / character à with just a. And à is only accessible with variant fonts which is not supported by most OS, and if you have your system locale as French every English word would have à instead of a.
1728 Bitcoin are minted a day right now (next halving in 2020 ), lets say you have 50% mining so ~900 btc a day. Thats ~4.5M at a 5k BTC. Sure you double the transaction confirmation time but the transactions won't be undone. You might have a chance to mine blocks twice as quick after the difficulty adjusts, but still no long term effects.
Ask HN: Database for efficiently storing many numpy arrays
I'm looking for a database that can store dense N-dimensional numpy arrays. Query performance is not as important as storage efficiency, the arrays are dense but mostly 0's and 1's and compress well.

I tried pg's array support (very slow) and storing it in pg's JSON field (also quite slow, but more acceptable)

I should also add, we're going to be writing a lot more than reading -- potentially for many processes, so anything with ACID-like support would be great.

But there must be dedicated databases out there for dense numerical data like this?
Calling for prices... outside of very special circumstances, no thank you!

Well, I probably can afford it, but if I have to ask for the price then the business is asking more from me than I am of them. I'll go with whatever competitor doesn't seem to be actively hiding something from me, thanks.
Did it work out for them?
+1 to this comment. It is a reasonably sized body of research, too. On top of this, scientific workflow scheduling maps to the classic scheduling problem, which is known to be NP-hard - the fact that the authors infer that automating the traversal is all that is necessary suggests that they have an incomplete understanding of the problem at hand.

For those interested, a nice list of workflow managers, engines, and even languages can be found at https://github.com/pditommaso/awesome-pipeline.

You were already given some solid advice.

If it generates no revenue and you don't want to be bothered by monetizing, the offer is definitely a no brainer and you should accept it!

There are two major advantages.

First, you will learn about selling a business.

Second, you will have money to bootstrap your next venture.

The amount you were offered is not a life changing amount aka fuck you money, but the entire experience is absolutely a gamechanger.

Articles like these frighten me. In my thirties, I am deeply worried about retirement, if that ever comes, and surviving in my old age. So much can go wrong.
