At home we have a 7kW charger (the most we could get without having to change either the main fuseboard in the house, or have stuff dug up).

That gives the Zoe a charge-time of just over three hours (as we have a 22kWh battery) versus over 13 hours for the Model X. That's 35 miles of charge an hour for the Zoe, and 21 miles of charge an hour for the Model X.

The Zoe can fast-charge at up to 43kW on motorway service stations, whilst the Model X and charge at 120kW. In the UK there are way more locations with fast-chargers the Zoe can use than there are Tesla superchargers.

If all/lots of the miners pulled out, then wouldn't the work factor decrease so that regular people could run it on their desktop machines? That is what happened at the start of bitcoin, right? Are miners that required?

> If it's faster, they can benchmark before and after

That goes bad very fast. I've worked with someone who tried winning arguments with one-line microbenchmarks; They even tried to convince me that I should always use undefined over null in JS since one is faster than the other (forgot which).

> Introduce them to the concept of static single assignment form

I failed with this as well; some coders don't trust the compiler/runtime at all. I had people tell me that garbage collectors don't deal with cyclic dependencies or that "simple comparisons" (<, >, ==) are faster than "compound comparisons" (<=, >=).
This should save anyone else a few clicks: https://www.amazon.com/dp/B073CPP581
Totally agree. There's no way I could've afforded a Tesla when we got the Zoe, four years ago. Including the battery rental the Zoe was £225/month, with a first payment of £5,000.

I've only been able to get the Model X because I've been irresponsible with money, and because we IT folk get paid more than we're worth to society.

Absolutely correct. Also, in the case of Vanguard, they're known as an "At-Cost" company. This means that they take no profit from the investors, and instead will return any excess money in the form of higher returns. This makes it very difficult to operate a profitable business in this space.

The "click bait headlines" are part of their substance. And, in many instances, it is the substance -- as it's the only part of the article people do read.
While not consistent with the aesthetic of the average Miami house, here is an example of integrating solar panels in to traditional roof covering: http://www.zepbv.nl/ . Look at the pictures in the carousel; one is a protected monument for which they got permission to put these tiles on.

So solar panels don't necessarily have to be large rectangles floating over the existing roof. Especially in a new build, you'd integrate them into the roof.
From anecdotal evidence, I understand that the algorithm has since been changed
Clearly Gef was a regular old European Tailypo. ;)

I love stories like these, where it seems like a legend gets perpetuated not out of malice or for personal gain, but maybe a sense of being “in too deep”. Assuming there was no Gef, there was no way to admit it while saving face, and the ruse wasn’t hurting anyone, so they just kept it going.
> It is interesting to see but I think Solidity is the first software language/framework that people with no experience writing it or running it, comment and write about it on hackernews as if they did.

It's interesting to see how the first virtualmachine specification for the first financial smart contract platform has overlooked all the pitfalls of the language-design industry and it doesn't look that a redesign is going to be addressed very soon because of the difficulty of the redeployment (as naturally backwards compatibility must be the first concern).

> Its hard to read the "I told you so replies", when the price of ETH has remained relatively stable during the news

Haha, so if the price is stable, this means that Solidity is not embarrassing? I'm sorry but this just means that people only care about security when their funds are the ones affected. Not about "potential" security problems or "design flaws" which sound too technical to them.
Parity is one of the core Ethereum clients, it is vetted just as much as geth is. The code that has this mistake was written by Ethereum co-founder Gavin Wood, in Ethereum's programming language called Solidity which was made by Gavin Wood as well.

I know you got burned in MtGox, but this has nothing to do with third parties or storing assets in some insecure manner. This is a fundamental issue with Ethereum and its community.

I wonder if malaria was really unexpected, since parts of Europe were malarious, too.

In Italy about one third of the country was affected[0]. Even Switzerland had serious problems with malaria, especially near the Lake of Bienne, because the alluvial sands caused the Aare river to repeatedly flood the plains between Murten and Solothurn, turning agricultural land into marsh[1].

In Scandinavia pollock is part of the traditional cuisine. Some people fry it up [1], but it's mostly found in things like fish balls [2] and fish cakes [3] where the meat has been turned into a paste (other types of fish such as haddock are also used).

According to the first article, pollock is low-fat/high-protein, is sustainably harvested in Scandinavia, and is also one of the cheapest fish you can buy.

My thoughts exactly.

The movie depicts a future in which nourishment has become purely functional -- not by choice, but because food resources are so scarce. (And to top it off, the function is served by the worst "waste" imaginable).

Now, instead of food, the scarce resource seems to have become time.

I understand that Soylent serves a purpose to some, but I believe we should strive to move away from that dystopian nightmare, instead of succumbing to it.
Why are solar panels reflecting light at all? Wouldn't that immediately lower the efficiency? Is it just that glass or whatever material is in use is the cheapest method of protection while letting in some light, or does physics say that all transparent materials must reflect something?
First of all, AWS is very very expensive and tries hard not to compete on price with other players. They are there to make high-margin profits, not to give you efficient and resilient storage. They don't actually care about efficiency, to the point, that they probably aren't even doing reed-solomon yet.

Second, hardware-level reliability doesn't actually matter for any distributed storage, reliability is achieved on the higher level with software. It's all about software. Decentralized global internet network is also better than any centralized equivalent, it has orders of magnitude more capacity and resilience. Ever noticed how bittorrent can saturate any link and how even google global caches sometimes have problems serving youtube videos for like months?

Other than that I don't believe decentralized laptop/desktop storage could even exist, for the same reasons why people don't mine cryptocurrencies on excess capacity on their laptops/desktops in the background. It can only be attractive to run it on dedicated storage nodes working 24/7 with good bandwidth.

Probably true, but 'twice exceptional' is the established term that describes what you are saying [1]. For example, someone who has 'genius' IQ (of 98th percentile) along with an uncommon neurotype (ADHD, autism-spectrum, dyslexia). These people often don't fit the stereotype of 'genius' nor their neurotype - and so are double 'misfits'. Probably the term 'twice exceptional' was chosen as more tact than 'double misfit', as these people often not accepted to normal society, especially as youth.

Ternary is the only option if you are using "B ? X : Y" as an expression, want to get the value of X or Y.

If-else is the only option if you want to have multiple statements in a {} block, instead of only one function call.

So it seems more consistent to use ternary for expressions and if-else for statement control flow.

I think it depends a lot on the market you're going after.

If your market is price-sensitive, either because you're selling to consumers or because you're selling to small businesses who are usually stingier, then competing on price can work, and to the extent that you can be the product that these guys get compared to you may be able to ride their coat tails as they spend on marketing the category.

If your market is not cost-sensitive, consider open sourcing your software and then selling consulting services for it; your customers may even contribute patches back. This will probably set a ceiling for how successful you can be since contracts will naturally top out at some value because companies can always take your open source code, but it may let you compete.

There are probably other strategies if you want to compete, but realise that you will have to compete and you will have to tailor your strategy to you customers.

It's been around a long time and bitcoin hasn't been changed to take advantage of it.

Ultimately, the community seems to have a big say in bitcoin and it's not limited to a proportional share. The community includes at least {holders, merchants, miners}. It's in their mutual interest to preserve stability but if one group acts in their exclusive interest to the detriment of the others, it makes sense for the others to consider a fork.

> I was wondering, why the bitcoin owners themself cant't decide. ... should have more to say about it.

Ultimately that sounds a little aristocratic and bitcoin itself seems more egalitarian. Regardless of philosophy, the blockchain is defined to be a consensus of a set of computers running software. Anyone of us could write new software to take the bitcoin blockchain into a new direction with new features. If we could convince some folks to run our new software, we would have our own fork. If the features are compelling enough, we could take the majority of nodes with us. Decentralized and fairly democratic -- you can have your blockchain and we can have ours.

Right, I am saying the analogy I responded to is flawed. Ethereum doesn't invite people to violate the intended use of the contract. It's like claiming that if a corporation got hacked due to lax security, then those hacking are in the clear because that corporation invited them in

If we are building homes "solar first," as opposed to tacking them on existing homes, there is a lot of options to better integrate the panels into the design of the house. For example, part of my roof is not visible from the ground, that part of the house has cheaper roofing material that isn't aesthetically appealing whereas the part of the roof that is visible has nice shingles. You could easily add some solar panels to the non visible part and nobody would even notice.

There's also the mere-exposure effect that will play out, people tend to develop a liking to things just because they are familiar with them.
I will never understand why these examples are considered abuse as they exhibit standard behavior.

It's just as if I were to write the following JavaScript:

I'm simply using a ternary and a bit of reflection, but the arguments regarding "correctness" this engenders...
> it ends up pricing working and middle class families out of homes in the long run

Considering the locality, I wouldn't be surprised if that was part of their underlying agenda.
actually the best practice is not writing your own code and using thoroughly audited industry standards. Writing your own smart contracts for things that other people have already done and secured is akin to rolling out your own cryptography. Obviously, just like it's happened with openssl in the cryptography equivalency, this can also go wrong, but it's less likely.

If you write your own you should get your code audited by a specialist, or many, before deploying.

All price-related articles should not be upvoted and/or should be flagged. They serve absolutely no purpose (at least on a platform like HN) other than to get those who have already invested in that certain coin to benefit from other buying it later when they see the news that the "price is rising" because of the fear or missing out.

People should be submitting and upvoting only technology-related articles about the coins. But this is just my opinion.

> Are miners that required?

Yes, we need miners. But yes, you're right, the difficulty is adjustable, so ultimately either we need miners[0] or we need miners[i].

If there's any value to be had for a coin and the PoW matches existing hardware, it's likely that miners will show up.
That's awful

What are people expecting with that?
Yes because that would still be a crime. Expanding on your analogy - if I declare right now that it's ok to murder me, it's still not ok to come and murder me. Same principle applies to EULAs and Terms of Service, you're not bound to it just because it's in there.

If the hacker was entitled to those funds based on the agreement between the concerned parties (implicit OR explicit in the contract) it would not be theft. But it clearly isn't their Ether and the implicit agreement behind the contract stands.

Basically human ethics, morals and the legal system will always trump code.

This isn't a particularly good introduction to quantum computing. The fact that we can't scale down transistors into the quantum realm doesn't have much to do with the real motivation behind making quantum computers. The real motivation for making a quantum computer is that it allows us to perform algorithms that exploit the quantum behaviour of qubits.

To give a concrete example of this, there is a basic quantum logic gate called a Hadamard gate. This takes a qubit in the state |0> and transforms it into a qubit in the state (|0> + |1>)/sqrt(2). The resultant state is what is known as a superposition state - namely a superposition of both the |0> and |1> states. You can think of the |0> and |1> states as being analogous to the 0 and 1 states of a traditional bit. What this means is that when the qubit is measured (read queried) it will return a value of 0 or 1 with equal probability.

The point I'm making is that this is radically different to traditional computing and isn't simply just the next step along in 'valve transistor -> semiconductor -> ?'
