" why do they call them crypto-currencies then?"

They call then 'crypto currencies' because they are 'totally cool' and 'trendy' and full of 'hype and future' - to gloss over the actual facts of what they actually are, in financial terms.

Where there is undue investor sentiment, and an inability to map the real meaning of the financial instrument - then those issuing whatever-it-is have significant leverage.

The biggest story of the 2010's will relate to the fact that most in 'tech' are viewing crypto-currencies from a technological perspective, while not having sufficient background to see their relevance as financial instruments.

Yep, this is what always happens with these types of applications. There was a whole slew of these type of tools in the 90s dubbed '4GL' with the idea they were a level above traditional programming (3GL) where business people could drag &drop their way to a new app.

It was a disaster and none of those 4GLs are around anymore. There is no interface that's as easy as sending an email to a developer saying "I need an app that does this..."

I'm very skeptical of Magic Leap, but I really do hope they succeed.

Mostly I'm wondering how many examples we actually have of Magic Leap type situations actually ending up being a success.

While the iPhone was a breakthrough, it wasn't so much a breakthrough in pure technology (rather, it was mostly the innovative combination of existing tech). Furthermore, it had the weight and expertise of Apple behind it.

What examples do we have of companies similar to Magic Leap, where the success is dependent on true technical innovation in a space where they compete with some of the best and brightest working for BigCorps? Honest question. While I can think of many cases where the result proved to be 'vaporware', I can't think of many (if any) success-stories in this particular kind of situation.
Ask HN: For a dependable desktop Linux, is there anything other than Ubuntu?
I'm a long-time Windows dev looking to finally migrate to Linux for the long term, and hopefully get some advice along the way.

I'm looking for a solid, dependable desktop experience. If I was younger I'd just install Arch and tinker away, but now I want something that works first time, every time. (Basically, I don't want to spend three hours re-configuring ALSA just so I can watch Youtube.)

Ubuntu looks to be the best bet for this, but people always have their complaints and alternatives. So HN, can you recommend me a distro?
They do not have to. If Kaspersky blocks the CIA backdoors and McAfee blocks the FSB backdoors, it will be fine by me.
network calls for tracking and ads is already a huge performance problem on most sites, but it is still a thing
That's a simplistic view ignoring information asymmetries, externalities and natural monopolies.
I usually describe Arch as the simplest possible binary distribution. It's just a thin layer (pacman mostly) on top of vanilla packages. This reduces complexity a lot. I understand most of what is going on in my install because I explicitly configured everything, and packages don't contain weird patches.

While I love Arch's ethos, I think the next step in distributions is to embrace declarative configuration, non-destructive actions and reproducible packages. NixOS & GuixSD provide this. And luckily there's still a lot of Arch ethos in their implementations. Namely, that your base system is totally barebones and you need to add (declare!) whatever you want to have.
Second, facial features are more unique than fingerprints - according to apple's own presentation, there's a 1 in 10.000 chance that prints from different people would unlock it. With face ID, this becomes 1 in 50.000 (iirc).
This "configure and set up everything yourself" bit is overstated.

It's not like Ubuntu, or similar batteries-included distros, doesn't require configuration and tweaking to get it your personal liking, anyway. And it's not like you cannot make choices during installation that affect the final state of your system. The difference between the Arch manual installation process and Ubuntu's is simply that you use a CLI and start a few scripts instead of pointing and clicking.

The amount of configuration necessary is exaggerated, probably by people that want to portray Arch as this expert-user distro. Once you've done e.g. "pacman -S gnome gnome-extra sddm && systemctl enable sddm", you can just boot into your graphical desktop and start using it just the same as Ubuntu, no extra configuration steps needed.

And, like I've said, for the nth time, use Arch-Anywhere to get a similar installation to that of Ubuntu.

I've been very impressed by Arch. Yes, it's a rolling release, so you have to update your system now and then, but this is a good thing--install once and run an up-to-date system for years on end. Unlike Ubuntu, which is outdated already on install, and if you want to upgrade, good luck with that process if you've installed a sundry of packages. Eventually, with an Ubuntu system, I've always started suffering from package-related problems, breakage, dependency issues, etc.

I won't detail all the problems I've had with other distros, suffice to say I've had none of those using Arch.

These supposed to "just work" distros haven't lived up to that in my experience.

Ah, right. You are so brilliant that you don't need to study anything. You can just know that most of a field is bunk because you perceive the practitioners as "extreme-left fanatics". Fake science!

You also get to ignore any article about scientific research (even if it is written by a scientist) because of those darned politically biased journalists. Fake news!

You have constructed a nice, comfortable political bubble for yourself. One you're only willing to talk about under cover of anonymity. This could be because you are the true lone genius you see yourself as. Or it could be because you are picking and choosing anything that you find politically inconvenient. Perhaps, as a genius, you can guess which one I'm thinking here.

The issue is not forking. It is the build infrastructure to produce all the builds for each OS, architecture, and the desired plugins. This is added value that Caddy adds.
It would be great for a replicated infrastructure to materialize. If it is well maintained it is even likely to overtake Caddy in terms of users, because it would be free software.
Why? It isn't an ad. Most users block ads because they find ads annoying, not because of script bloat.
> Dropbox does not encrypt your data server side (or at the very least, can easily decrypt it).

I think claims like this need to be backed up.

Now, obviously a biased source, but Dropbox itself says this:

"Each file is split into discrete blocks, which are encrypted using a strong cipher. Only blocks that have been modified are synced. Each individual encrypted file block is retrieved based on its hash value, and an additional layer of encryption is provided for all file blocks at rest using a strong cipher. Both dedicated internal security teams and third-party security specialists protect these services through the identification and mitigation of risks and vulnerabilities. These groups conduct regular application, network, and other security testing and auditing to ensure the security of our back-end network. In addition, our responsible disclosure policy promotes the discovery and reporting of security vulnerabilities." [0]

So we have files that are broken apart, each part encrypted, then the whole combination encrypted again, then lots of security auditing in-house and outside, and with incentives for people that discover flaws to report them. That seems pretty industry-standard to me, but I'd like to know more.

I really have some difficulty imagining a company like Dropbox, which knows how important the documents it stores are, being careless with security. Not saying they may not be, but it's going to take more than an HN comment that includes some politicized perspective about the Bush administration to convince me.

Furthermore, this article [1] claims that Dropbox encrypts files on the server even stronger than Google does. It also points out that user behavior is usually the main security hole, which will always be true with any service.

If your marginal utility function is driven by money and career progression rather than a desire to write papers about your particular hobby horses, you don't become an academic economist, period.

If your particularly hobby horse is writing papers about economic elites ruining the world and mainstream economics being wrong then ample funding opportunities are available even from members of the economic elite, and your book will probably sell more copies too. And you probably don't prize the opportunity for tenure at Chicago that highly unless you actually admire the school's economists anyway.

When the most influential economists of all time are Marx and Keynes, and Stiglitz, Piketty and Krugman get more public attention than most of the rest of the profession put together, it's more than a little difficult to argue that academic economic discourse is highly constrained by the class interests of billionaire rentiers.

Nice catch. I have read several of the culture books and didn't put that together. Going to read Player of Games next now!
It depends on what you find enjoyable. If you find mining asteroids or mission running enjoyable, all the power to you. But that's not the way EVE is portrayed in news articles. Articles are about the betrayals, the massive battles, the wars. Few people will ever reach that level of meta-gaming and those massive battles don't happen on a daily basis but several months apart, neither are they very fun to participate in. Unless, of course, you consider listening to your fleet commander and pressing a button every few minutes fun.

For the non-EVE players: EVE has a system called Time Dilation, TiDi in short, that slows down the gameplay to give the server more time to process. It gets as slow as 10% of normal speed, which doesn't sound all that bad at first, except that stuff tends to no longer work as expected when the server load increases beyond what is manageable on that level. New commands are thrown on a stack and get worked down in order, which causes massive lags between giving a command and the game executing it, if it doesn't get lost somewhere along the way.

Those massive battles with thousands of players sound awesome in writing. They're very boring in reality.
Some places, yes. Unfortunately, in most places we don't. Usually wealthier neighborhoods get underground cables, but even then most long distance cables are up in the air, so if a hurricane destroys a long distance cable, you are screwed even if you have underground cables in your local neighborhood.
At a casino, you are paying ~5% on the dollar and getting some entertainment in return.

With ICOs, in the long run, you might end up paying ~100% on the dollar and getting nothing in return.

The asymmetry between those issuing 'coins' and those buying is considerably greater than the 'average losses' of 5-10% or whatever a gambler might have at a Casino.

Also - a lot of Casinos end up losing money because they have to 'give too much away' to consumers in terms of the experience, food, drinks.

More wealth-per-dollar will be transferred to investors from ICO's than at Casinos.

Which is why Hedge Funds are lining up to back ICOs - and not Casinos - it's a better return for them.

I meant more as in "as someone wanting to use something", rather than the security aspect.

Most AUR packages I have seen have been incredibly easy to read - if you really don't want to use them, it's still a good framework for making your own packages much more easily, so you can install from source without dumping unmanaged stuff into your system.

If you are interested in Arch but not the overhead it entails, you may wish to consider Antergos https://antergos.com/

It's basically a fully set up Arch with sane defaults. Lets you have the rolling updates and other benefits, without requiring as much energy to set up.
That is the underlying problem though. There is no "shopping around". Either your plan allows it, or does not. If you need a procedure, your choices are effectively limited to who is on your coverage list.

FWIW, I live in an area where there is ONE healthcare option (Racketeering/monopoly). I (as an independent consultant) pay $1640/mo for a $5,000 family deductible. So basically, I pay over $19,000/year for the PRIVILEGE of paying another $5,000 and that's assuming I only go to the doctors "they allow" me to go to. (it was $800/mo for a $1500 family deductible prior to ACA). Obama can EABOD.

The only people who like the ACA are the people who don't have to pay for it.

Edit: Also I was in an MVA in July, the Emergency Dept. didn't accept my insurance at all - so who gets the bill? I do. The MVA wasn't my fault, but that bill is still my responsibility.
That's just not true. My desktop is Arch and I run maybe 5 or so AUR packages - and they are all for dev tools. You can definitely run a completely functional desktop without them.

No, I don't think it's anyone's job to simply "get the best deal", at least not from an ideal-social standpoint. I think employers (whether government or not) should adequately compensate their employees. And I think employees get a much fairer shake in negotiating that compensation when they have the backing of a union.

What is "adequate" I can't say, but without knowing more I'm not prepared to simply swallow the line that $400k is somehow totally outrageous. A lot of less useful people make a lot more money for a lot less work and personal risk.

Anyway, $400k was only the last year of salary this guy made. The article is suspiciously quiet about what his compensation was over the course of his whole career.

I think your vision may be colored a bit because here on HN everyone seems to think that manufacturers can just sell direct to consumers easily by tossing up a Shopify page and letting nature take its course.

The true value of a middle man is connecting buyers and sellers who would otherwise have no idea the other existed, or otherwise facilitating the transaction.

Here's an example that I'm currently involved with. I was approached by someone to create a device that's needed on the market, but doesn't exist. I'm quite capable of building the thing and familiar with the domain, but never knew the thing was needed. Similarly, the company approaching me doesn't have the internal skills to build the device, but they can sell it. The market for this particular device isn't very large (it's only businesses who have machinery that was built using a particular older technology and need to have repairs done), and there are alternatives, so that explains why no one is building these.

In this case, the company that approached me -- the middle man -- has excellent knowledge of the market and its needs and how to best serve them. I, the producer, had no idea this product was needed, and even knowing that now, have no access to this segment of the market, and it's simply not large enough to make it worth my time to begin a marketing effort in that direction. Similarly, the end customers have never heard of me, and have no concept that such a device could even be built.

So there you are, a middleman has just added value by offering to buy something that I otherwise would not know to build, and by selling it (along with other products and services), to a very underserved market that otherwise would be forced to purchase newer equipment they otherwise don't need.
The same guy citing national security concerns for this block also proudly touted national secrets. Weird.

I've owned Photoshop since it was distributed on diskettes and I'm still befuddled every time I need its impressive power. (I'm not a professional graphics/photography person so I use the program only a few times per year now.)

I think this is a really good analogy to using pro-level text editing tools (e.g. Emacs or Vi). A mouse is great for poking around menus and operating sliders in a new or unfamiliar program, but Emacs and especially Vim are so fast to use without a mouse that it pains me to watch other programmers editing while using one.

ST is a fine editor, and I use IntelliJ for Java, but I've already spent the time (years) learning Emacs. Is it worth it for me to start over? No. I use IntelliJ for Java programming, but I use only its basic Emacs keybindings and the mouse for everything else (befuddled like I am in Photoshop).

As I said, it's a different definition of "just works" - obviously no non-technical person is going to run Arch - it's never going to be Ubuntu and it's not trying to be. I wasn't trying to make that claim.

As a power-user, Arch "just works" for me far more than other distros have, because I know the system and it's simple, I've never had a problem where I didn't have a handle on it.

"The point is that these services work via e.g. the ethereum blockchain (and the best of them will actually have something to gain by being decentralized and trustless). Good luck sending euros to an ethereum address.."

Nobody cares about the issue of decentralization, but a small group of people, moreover, their concerns are not practical, they are intellectual. (Unless they are trying to do something illegal, in which case their concerns would be practical)

From the average 'token user of Euros or Dollars' perspective - the current financial system has incredible integrity. There is zero advantage in 'decentralization'.

There is zero risk from short term holding of any major currency. And they're massively liquid, especially in the natural region of that currency.

100% of 'Ether-anything' are nearly useless to the average person anywhere, whereas dollars are amazingly useful to Americans and others, for example.

If there were a single, global, well thought-out 'Ehther' type currency, that were used in major and minor transactions - I can see some theoretical value in that. Conceptually, it's not crazy. But in practice, especially in terms of these small, one-off ICO's - they don't make any sense at all.
Some are. Manhattan is a noticeable case where pretty much the entire power grid is buried.

https://www.washingtonpost.com/news/wonk/wp/2012/07/25/why-m...

>All told, the Edison Electric Institute estimates (pdf) that some 18 percent of the country's distribution lines are buried. For the transmission system, only about 0.5 percent of lines sit beneath the surface. "Undergrounding an entire power system," says EIA, "is considered cost prohibitive." Instead, most utilities will just try to bury a few key lines.
