Sure there's lots of fraud, excitement, and ignorance right now in cryotocurrencies, but there are also fundamental problems with the current attempts. Distributed consensus means eventual consistency and/or slow unreliable transactions, I'm not convinced that's a good idea for a payments network.

The article makes the point that many people putting money into these schemes know nothing about the tech involved or the possible applications/drawbacks, they're gambling based on hearsay.

As with most bubbles, what comes after probably won't resemble what got everyone excited, and early investors will lose their money. So it's understandable many are sceptical.
I was recently invited over a friends house to get together with a few others to discuss bitcoin and bitcoin opportunities. All mid 30s, non tech day jobs and people I would consider intelligent. They had no experience with equities, no experience with forex, and were heavily researching bitcoin mining systems. It seemed as if bitcoin just popped up on their radar and really had no understanding of bitcoin or other cryptocurrencies and I got the sense that they felt like they were getting in on the ground floor. Maybe?

Hardware in human eyes is actually pretty bad. Modern cameras can record and process more information in higher resolution and dynamic range.

The advantage is mainly in software. For example, I have a spot on my daily commute where I need to yield, but thick vegetation blocks the line of sight. I have to look for the signs of a moving car through the bush where there are some clearings, then wait to give the cars that I can't see the time to appear on the other side, if they exist, and proceed only then. I seriously doubt an image recognition system can do this.
> among relatively well-off 40-ish Australians

The same is true in the US. Note the ages and geographic locations of the people mentioned in this article.

Among well-off middle-aged (40+) Americans, in my experience it's more typical for people to compete to pay the ENTIRE bill, every single time, rather than attempting to share. Generally it's bad form to seem like you're competing to pay the bill, but very socially desirable to be known as someone who will pay the bill (and thus must have the money to do so).

Communism isn't genocidal. You should read up on what it actually is instead of relying on pro-capitalism propoganda. "Somebody died because Stalin/Mao" holds no candle compared to capitalism's "somebody died because housing, hospitalizing, and feeding the poor wasn't profitable".
I find the recent popularity of cryptocurrencies very interesting as I spent a lot of time in 2009^ studying and researching Bitcoin from the academic perspective of economics (My undergraduate degree).

In 2009^ I downloaded a BTC miner and had everything set up but then never started the machine because I was running folding@home and thought that was a better use of my distributed compute. Doh!

In my mind you can look at cryptocurrencies, and the idea of blockchain generally, in two ways. Either you evaluate it as how well it acts as Money or what it can do as a distributed ledgering system.

In the former case you need a comprehensive understanding of:

1. The history of money, which comes down to war and politics,

2. A deep understanding of what makes money work in it's three uses (store of value, medium of exchange, unit of accounting)

3. How it forms a scaffold in a modern economy.

The cryptocurrency-as-money perspective fundamentally has no legs, for numerous reasons, but primarily because it has no coercive power behind it enforcing it's use like all other currencies. A few people are trying it but it's no serious contender for legal tender anytime soon.

All of the "coin" that is created in these markets is effectively derivatives trading and should be avoided at all costs in my opinion.

From the digital ledger perspective there seems to be real value in that use case.

I have never heard of this (Wide Band FM Siren Noise) and I think it's a fantastic idea. Why don't we do this in the US?
> In that case you'd need an app on your Android phone to relay SMSes between the phone network and your web app.

I'm fine with that.

> The advantage of doing it via the carrier is that the phone is taken out of the loop and you're directly sending to the carrier via the internet.

The disadvantage of doing that is you than need to stay with that carrier. I'd rather be able to change if my carrier starts doing things that are shifty without needing to change the way I interact with my phone.

Sodium Benzoate Nonsense
Exactly. It takes the first mover to discover there's some value in new space, like early social media or Bitcoin. Because there's no roadmap, they early efforts often fail, and the later arrivals take the core, good idea and learn from the failures.

I think in the crypto space, much of the value will not actually be in P2P cash systems, but in P2P decentralised apps that will enable a decentralised web to emerge, and early adopters and network users will capture most of the value in these networks (instead of large centralised companies).

Also, having a new funding model (crowd funded token sales) could unlock massive amounts of capital to fund new projects. The implications of this could be unprecedented - so many ideas and talent, particularly outside the US, currently goes unfunded. I doubt that anybody, up till a few years ago expected to see a way that traditional funding models for new companies would emerge, literally out of the ether. Turns out there's a torrent of speculative cash waiting for founding teams (yes, at some point there will be a massive crash, but like venture funding post the dotcom, lessons will be learned and the valuable ideas retained).

> Covariance and contravariance are just monotonicity and anti-monotonicity

I am confused. It seems that monotonicity is a property of the function itself, that is, how it is implemented and what (type) it returns depending on what (type) it gets. In other words, we vary input value (real) type and observe what happens with the output value (real) type. Only one function is involved - monotonicity is its inherent property.

But covariance/contravariance is about '<:' relation between function signatures (the contract, not how it is implemented). Once this relation has been somehow defined, we can check, for example, if one function can be safely applied instead of another function. In other words, we vary signatures by changing input/output declared types and then decide about the relation among them.

Why do you say that monotonicity is similar or equivalent to covariance? They seem to be different properties.
Yeah that's true. Think of the npm ecosystem, the burgeoning Go ecosystem, etc. All full worlds with their own repos, etc.
But you can paint the car you are riding but do not own!

Ah yes, the narrative where libertarians finally see the value in politicians and crawl to them for help. Unfortunately for your fantasy, that's the opposite of what's happening. We're leaving the politicians at home and building technical solutions. What a world huh?
1000W m^2 is actualy closer to high noon at Kansas on a fully clear day (this is equivalent to 2,000 umol/cm^2/s-1) Equatorial solar irradiance is actually higher (closer to 1,050W/m^2) because the equator is just a bit closer to the sun.
If this is your fear how do you use any software?

MS could update your OS to do anything tomorrow, Canonical could hide some literal malware in any number of packages for Ubuntu tonight, Intel could write a backdoor into your machine in it's next microcode update.

And OSS doesn't fully prevent this either. GCC could add some kind of nefarious exploit in the next version of it's compiler (knowingly or otherwise). Just take a look at the underhanded c competition for just how scary easy it is to hide exploits in plain sight!

I can't even fathom the amount of work it would be to personally review every line of code that goes into your machine from the microcode up to the newest NPM module (even if it were all open and it was possible to do). At some point you need to trust someone else.
For that much data rclone might be better.
Possibly by someone trying to do good. More likely by someone just following their rational incentives. Very few people are 'evil' actors but most follow incentives.
Very few early adopters did any of those things.
For an OSS business application, Rundeck (http://rundeck.org/) is very polished and has a clean architecture. The concepts for setting up jobs, schedules, ACLs, etc, is clearly thought out and flexible.
Yeah, exactly. That's exactly how I feel.

If someone grabs a tab and sends me a Venmo bill, I'll happily send them their money. I would have rather grabbed the tab the next time. I won't be doing both.

(And vis a versa - If I say "I've got the tab" and the person sent me money, I'd be much less likely to invite them out in the future. I'd rather they just invited me out and grabbed a round.)

Comma.ai wasn't originally going to be open-source, Comma.ai intended was going to be a $999 proprietary retro-fit product. NHTSA (National Highway Traffic Safety Administration) asked Hotz to delay the launch on safety grounds.

He then open-sourced the software specifically to avoid regulation and safety standards.

"NHTSA only regulates physical products that are sold,” Hotz said.
“They do not regulate open source software, which is a whole lot more like speech.”

If the gig economy does not provide for self control of hours then I'd say the central pillar of the gig economy's value proposition to labor is gone and at that point it needs to be readdressed.

To date, thats literally the way people are attracted into the gig labor force and is central to what it means to be gigging.
I'm not from the USA as I see you've probably presumed, also labour markets and internal politics are vast and different form country to country.

You stated very explicitly "Each and every employee law" which I contrasted with a very simple observation of the legislation process. It was my intention to stress that the law making process is anything but direct and is full of noise, corruption and, yes, interest groups with narrow interests. In many countries of the former eastern bloc in Europe, bloated public sector with the backing of public worker unions are efficiently blocking any reform incentive of the governement and the labour market.

Qouting a few examples is barking at the wrong tree since I never contrasted that employee law may arise from horrible working conditions. I only gently contrasted the "Each and every" part which is a very strong and, dare I say, ignorant statement.
If you think you can't get caught because you use Tor, I know of a few people who can testify otherwise. See, e.g., Ross Ulbricht and Christopher Grief, to name a few.

"Avoid highway braking" was drilled into us as 15 year olds in drivers ed. That still is one sacred rule i swear by.

Chain reaction braking, unnecessarily has caused many accidents (witnessed by me). Driving on I-95 in Florida you have (upgrades) where bridges are were built (limiting sight). Heavy congestion causes unnecessary braking. Several rear ends were witnessed on a trip north from the keys.

Never highway brake.

Im glad you posted this because it is good to know what cars may not respond the way a human was trained.

This "200+ mph self-driving cars" thing gets repeated a lot on HN but I've never seen anything to suggest that it would be remotely fuel-efficient. There is a reason why today's high-speed rail rarely exceeds 200mph / 320km/h, namely that around that value, wind resistance starts to exhibit cubic growth. Even with ultra-dense automated slipstream driving, I can't imagine this being very efficient. Some citations would be greatly appreciated.

Tyres might be an even bigger problem. See the Bugatti Veyron: "It uses special Michelin PAX run-flat tyres, designed specifically to accommodate the Veyron's top speed [258mph / 415 km/h], and cost US$25,000 per set. The tyres can be mounted on the wheels only in France, a service which costs US$70,000" from https://en.wikipedia.org/wiki/Bugatti_Veyron

> What's preventing people to host German sites from an entity outside of Germany though?

Nothing at all, that's the thing German legislators seem completely ignorant about like a lot of other facts about the Internet. But what German news company would go that route? Not a single one because it would make them look like they want to "break the law on purpose".

So they all keep on hosting in Germany and moderating their comments or sometimes do not allow them at all because certain topics are way too much effort to moderate.

Keep in mind: This has been the state of things for decades and if you ask any regular ass German about this they wouldn't even know about it and instead keep on complaining how it's media companies who are censoring them and their opinions, even tho these companies are pretty much forced to do so by German laws, at least if they want to prevent massive legal issues for themselves.

It's a very comparable system to how Germany censors/bans media like movies, music or video games. It's not the German government "banning" certain media, the German government merely puts very heavy restrictions on certain media, which, for all purpose and effect, makes it impossible to sell them.

That's how you create an system of censorship even when your Grundgesetz (German constitution) quite clearly states "There shall be no censorship", just don't call it censorship but rather "youth protection" and you are a-okay.
I disagree that it's flamebait, but I do think this is all off-topic. But I just can't keep my dumb mouth shut when someone says that enforcing one's private religious views on others via the government is just fine.
Ever heard of these things called "hashes" a.k.a. "dictionaries"? They are
magical boxes for elements that are indexed by name. You build such a magical
box of seen elements while going through the checking loop and you get the
time complexity of O(n) or O(n log(n)) instead of your current O(n^2), so it
won't explode when you get more elements passing through the code.

Note that this was conceived in just a few minutes of reading your code,
deciphering syntax only remotely familiar, and figuring out what was it
supposed to do, all with cold start (I haven't written much today yet).
Something went wrong with your thought process.

Needing to assume that the contract author didn't make a trivial mistake (like leaving off `internal`) that makes all your tokens fall on the floor seems like a pretty sizable chunk of trust - and that's also assuming everybody involved isn't malicious.

Since you'd be the only owner of the S-Corp, according to my CPA, they can be issued at-will (you don't need to hold a meeting with yourself).

Sure, you CAN verify Turing machines, but verifying languages that AREN'T Turing complete is sufficiently simpler. So why not make your verification work easier by using a total language? The only real argument against that would be "we can't do what we want in a total language".

I don't buy the argument that what people want to do with smart contracts requires Turing-completeness. In fact, as time goes on I become more and more convinced that Turing completeness is highly overrated. Almost all code wants to do finite and/or structurally inductive operations. The only case that doesn't fall in that are things like request loops where you want to "infinitely" wait, process request, loop back to waiting. But even those things can be done in total languages via co-induction, so exactly why do we want to make our analysis/verification work more difficult by using a non-total language for things like Ethereum?
Subjective in the sense that something you find morally wrong i could find it morally right, or morally neutral. E.g. for the specific issue of this thread, I consider what they did to be morally neither bad or good. The developer has no obligation(moral or legal) to check with me before commiting stuff in the repo he controls. He doesn't owe me anything. In fact I could say that I owe him (morally, by my moral standards, because I 've been using his code). But that's just my view.
Doesn't the Bitcoin network depend on miners to process transactions? Like, no miners = no transactions processed?
So a discipline that isn't able to conduct repeatable studies to support its key principles, can be computerized? OK.

Plenty of cheap inverters - design your system to run at higher voltages. Run your panels in series to get to ~120V first, then get a simple switch inverter since you're already matching (in North America where I am) your mains voltage, those inverters are cheaper and usually more efficient. Then you feed that into your MPPT, which should have the step-down for 12V battery charging and cleaning the input 120VAC power..

this almost throwaway line at the end caught my eye: "The safest bet, then, is for automakers to use an array of sensors, in order to build redundancy into their systems."

experienced engineers know that redundancy is a double-edged sword. what do you do when the data from redundant systems disagree? having more data sources means dealing with more edge cases. a single reliable data source (as in the limitations and biases are well known) is better than two less predictable ones.

i'm not saying that that's necessarily the case here, but it's not as obvious as this line suggests that the answer is just to add more kinds of sensors (and thereby add more diverse data sources).
I agree with you. The one silver lining is that the autonomous car will (hopefully) have super human reflexes and will be able to brake in time for some of those...hopefully...
>"It marked Paint as 'deprecated' in a list of apps and features that may be removed from the software, meaning the app is 'not in active development and might be removed in future releases'."

Not quite "killing" just yet. I imagine that either Paint3D or a similar program will be phased in to replace it, though. Microsoft is pushing the creator angle on their in-house PC designs, and I wouldn't be surprised if they have a more serious "prosumer" application in the works.
In the usa, most 'non-profit' are specifically orged for making huge profits. AAA would be a prime example. The church of towing cars some call it for using the loopholes.
The 5 stops I use most are (in order of use):

- 53rd Street Metra (bicycle/coffee shop)

- Randolph Street Metra Station (~8 or 9 shops of various kinds)

- Merchandise Mart Brown Line (attached to a mall)

- Clark & Lake CTA in the Loop (entered via 2 different shopping centers or the street)

- Randolph/Wabash CTA in the Loop. No shopping at this one as it is an old, small elevated stop. That said, in the little space it does have available there is vending so it has been commercialized.

The red/blue lines are good examples of what I mean by not having space. Where would you put shops that would generate enough revenue for the work of putting them in to be valuable? The 95th street station used to have a newstand in it but doesn't anymore, I assume because they couldn't find tenants.
That author was me with bitcoin, I perhaps understood it on a technical level better than my friends, but I thought it was silly, they didn't and now they're bitcoin millionaires.
There are many shops in the red line. They are only open during the day/rush hour. Some of them used to be good (like a mini c-store or a Dunkin donuts) but often they replace them with something stupid like a popcorn stand, or closed them all together.

Obviously there is also the pedway at Lake St, and merchmart, etc but that's not really what we're talking about.
