If you read Vitalik's post it'll give a very good run down on side chains. http://bitcoinmagazine.com/12349/side-chains-challenges-pote...

Sidechains have issues in the current incarnation that we have been shown; they need to be mined and a 51% attack on Bitcoin will enable the miner to gain access to the coins that are in the Bitcoin blockchain waiting for release via the two way peg.

If these issues cannot be solved then Vitalik may be correct that Ethereum based side chains might actually be a better way as it seems Ethereum is designed to handle this type of advanced contract.

Either way, whatever coin (bitcoin or ether) implements these side chains safely and correctly will likely win as being the foundation for the future of cryptocurrency/platforms.

The side chain idea allows the native cryptocurrency to compete and win out over other competitors. Want faster confirms? Use side chains. Want Zerocash anonymous transactions, peg into Zerocash and peg back out again. I believe the future will be a battle between Bitcoin and Ethereum with a major war zone being sidechains.

Also consider this: If cryptocurrency can have on top of itself many other applications built (decentralised: {web hosting,web app hosting, databases, information, computing engines: {search, math, compute}, contracts, code}) then does that coin itself eventually gain 'intrinsic' value via being the foundation of all these new systems?

Imagine a TOR that is based entirely on the greed incentive and not just good will, where the entire system is an Ethereum contract. Imagine an open source google search where the code is run entirely on top of the nodes and each search costs 1 cent in ether to be paid to the nodes for hosting and running the code.

If this happens, that coin becomes pegged to a brand new internet running on top of blockchains. Just something to think about.

Rust will never be a 'gold rush'. The human brain will always be the limiting factor no matter how good a language is. The true gold rush will be when computers have strong A.I. and create everything for us, from concept to implementation.

The World's Most Toxic Money Pit
There's no platonic ideal of Security that exists in a vacuum, unaffected by the economic/convenience/performance/etc costs. The clearest example here is post-9/11 security, but this trade-off exists in EVERY security system, far from being an "issue" with certain projects. As far as I'm aware, this is considered a pretty fundamental tenet of security in a pedagogical context. Now of course there's still room to disagree with the level to which each project sets its security/cost-avoidance slider, but it's hardly black-and-white.
This technology was unavailable to the public - until now!

I'm somewhat surprised that they didn't go for bare die versions of ICs like the MCU, since COF is another quite-established technology for cheap flexible electronics.

> Criminals may not CARE about breaking into someone's computer or router, but that doesn't mean they're capable of doing so.

The problem with this line of reasoning is that it covers such a small number of people. The only people your argument covers are serious criminals who a) are too stupid to be able to download a simple tool to exploit routers with unpatched vulnerabilities from last year and yet b) are still competent enough to use Tor without doing anything that would reveal their identity.

And that also excludes the most serious criminals because the set of people who can break into the computers of large organizations to commit crimes is essentially a superset of the set of people who can break into an unpatched consumer-level router.
Are you calling Anandtech a mysterious, unnamed source?

No, I was referring to the general claim by articles that "sources" from "inside Qualcomm" gave them such information.

However Anand's comment was...dubious. Qualcomm doesn't generally publish a roadmap, and there was a single leak of uncertain origin that actually showed Qualcomm's own 64-bit IP (their own designed cores) in Q4 of 2014. So not only was Anand wrong about what the supposed roadmap contained, the roadmap itself has absolutely no credibility to begin with (even if it were made within Qualcomm, it could easily have been made by a division such as marketing that is going on the most certain of facts, while engineering may very well have had such a plan to adopt ARM's design for iteration 1, and then customize for iteration 2).

Making any broad claims about Qualcomm from that is ill-informed rumor mongering, which Anand is not always above.
Disruptor is an application of the pre-emptive threading model. It certainly it interesting but to put it in the same pedestal as CSP and Actor model is wrong. (Also the stability of Disruptor approach in face of competing applications on the same machine was an issue last I checked.)

i dont see how this belongs on hacker news, other then the fact that not mentioned in it is that the spike in wealth accumulation of the top 1% is in part largely do to the tech industry - whom are mostly liberal 'we are the world' people who actually don't really give anything back.

i dont know what the makeup of the population in the 1% is for certain, but i do remember that back in the late 90s bill gates had more wealth than the bottom 50%. fast forward to today, and you got the page, brin, zuckerberg, etc worth tens of billions of dollars each. new billionaire from whatsapp whom less than a year ago posted something along the lines 'hey bitches, check out my app'.

the wealth distribution is typical of such a boom, like the steal industry in the late 1800s. today's boom has an unprecedented 40-80 billion$ of month of free gun powder thrown under it by QE3. such reforms supported by those like krugman, yet he's the first in line to complain against those who are becoming easy billionaires off it.

Same here. By the way, I need this. I'd be particularly interested in seeing a wide range of devices in each form factor in order to illustrate the variability that exists in the ratio of CSS pixels to actual inches (for example, Kindle Fire HD 8.9 vs. Kindle Fire HDX). Also I need an option to include a variety of hands to covers a range of ethnicities but also hand sizes and ages to illustrate the (im)practicality of touch target sizes.
I've got mixed feelings about Steve Gibson. He's clearly very, very smart. But he does tend to be a little overdramatic, and I recall him railing against raw sockets in Windows XP a number of years ago.

I'm part of the team behind this project. Your guess is very much on the money on both counts - we can't deny we'd love to blow past it, and the fab process for many of the components is already set up.

One other factor is that our company, and our partners in this project, really want to get these technologies out in the open for people to use and play around with. There is a lot of innovation happening with Printed Electronics but unfortunately it has mainly been kept within R&D labs and B2B. Developing this project was an investment we were willing to make mostly internally.

Thank you so much for the enthusiasm!
A lot of this is over kill. FRP has a lot of complexity overhead before things get easier. For task like simple data binding as shown by author, your regular data binding library (angular, knockout) is enough. Doing the same with Bacon only makes it more complex.

FRP only starts to excel when you need to weave multiple signal sources together. Examples includes key combination for certain hot key. Or signal switching when implementing drag and drop.

Delphi – why won't it die? (2013)
There are people who find that complexity and bloat matter across the entire stack, from the lowest level to your piece of software on top of it all. With such philosophy, it does not matter that your product might be simple and elegant, if it stands on the shoulders of a wild behemoth.
I totally agree that all software sucks, but, unfortunately, we have to use something and the list of alternatives isn't really impressing (maybe because it's outdated, idk).

> C, Go, Limbo.

It reminds me of some story about OpenSSL and… well. Yeah, Python sucks, Ruby sucks, but we have to use something for scripting and everything else sucks more, so… Also, Rust is more appropriate in list of alternatives, I guess.

> Perl, Ruby. ->> rc, awk.

I guess it's only about text processing inside of shell, so, ok, but it's only because our best shells still are awful. I guess shell of the future is something more like iPython, that is, something that allows to do real programming, so there won't be need for cryptic-syntax text processing tools. Yeah, not unix-way. Rc? I doubt.

> GCC. ->> 8c, tcc.

clang, you mean?

> Tk, textual interfaces.

Just no. Textual interfaces are the best, surely, but not always enough. And Tk is simple, sure, but cannot do everything Qt can. So, again, everything sucks.

> Vim, Emacs, nano, Eclipse, ->> Acme, Sam, ed.

So why it happens I never heard of Acme or Sam before? Maybe "ed" in that list could provide some insights?

> UTF-8.

Sure, but unfortunately it's slow as you don't have static offsets, so sometimes you have to use UTF-32 while processing.

Everything sucks, alternatives aren't any better. Well, may be only a little.

You're very right, we should clarify. The technologies not previously available to the public refer to the printed electronics components: electrochromic displays, printed carbon-zinc batteries, LED die chips on film, printed polymer solar cells and printed light sensors.
This interview with Paul Krugman discusses why the United States is becoming an oligarchy with increased inherited wealth. He reviews the book "Capital in the Twenty-First Century" by Thomas Piketty. A few years ago, Piketty published detailed statistics on income inequality over the last century. In his new book, Picketty considers his data on wealth inequality since the French revolution. No other economist or social scientist in history has had data as comprehensive as this, so you can imagine Piketty has a few interesting things to say.

The interview is a fine, but Piketty's book with historical data is great:

An interesting and related article is this one by Paul Bohm from 2011:
http://paulbohm.com/articles/bitcoins-value-is-decentralizat...

His conclusion:
"Is there value in Bitcoin? Let me ask a counter question: Is decentralization valuable? If you think that we'll increasingly lose trust in the central authorities that manage the infrastructure we rely on, you might expect Bitcoins to rise a lot in value. If not, that is you believe that authorities will be able to tackle the challenges of the future better in centralized form, then from your perspective Bitcoins don't add value. We'll see."
The tired trope that "they" "the 1%" are keeping secret information from you. And that you need to wake up etc. It's not intelligent discourse.
You should have probably listened to the interview before jumping to conclusions about the subject matter. The crux of the matter is (according to Krugman and the book's author) is not so much the high incomes, but rather than inherited wealth which is now growing faster than the economy. The initial wave of oligarchy happened while the country was industrializing and hence was swallowed up by the greater growth of the overall economy, then staunched further by very progressive taxation during the New Deal and WWII. Today the economy is growing much more slowly and any talk of wealth redistribution is a dirty word.

I like Tim Daly's viewpoint that we shouldn't just be writing code, but we should write manuals - giving high level overviews of our problems and specifying their implementation details inside the manuals. His talk "Literate Programming in the Large"[1] covers why.

The example he gives in his talk is the Axiom algebra system[2], which was revised to use literate programming style - the source code, with usage examples, is contained entirely within the books.

I agree. Using setState within a nested component should be limited to UI-only functionality, such as tab views or toggling menus or the like.

Even then, if one were to have a single object that store the entire state of the application, this object could easily be saved to localStorage or pushed to the network for syncing to other clients. If the user were to reload the application or perhaps resume use on another device, they would be presented with exactly what they left behind. The infrastructure and code to do so would be very trivial.

The days of state being spread over and managed by a number of objects has come to an end, at least for me.

I'd willingly pay that price if it delivers on what they said in the marketing. But it appears we'll have to wait.
This is important advice for consumer-ish software. But in other areas, it works differently. A product "grows up" as its original user cohort grows up, and that's OK.

I saw this in the music creation software space. Products start simple out of necessity. They are a good fit for a cohort of users with simple needs. But as the user cohort advances, they need and want more powerful features. Typically companies add the features to create a "more professional" product, rather than see their existing users jump to a competitor.

Of course after (say) 5 years of this, the product is no longer such a great fit for "beginners". So it creates space for a new product to step in, and with a fresh approach. Of course that new product will eventually accrete more features, too. Some manage it better than others, but they all become more complex. And so the wheel turns again.

At the same time, plugins provide a safety valve, as well as a way to form partnerships. Plugins can be a way to give certain features an "audition" before maybe rolling them into the product itself (or bundling the plugin, maybe with somewhat tighter integration than before).

TL;DR Products have a natural cohort of users. If the users grow up, the products do, too. Also plugins.
Article advises setting policies about what is normal, and then tracking. How does this resemble an 'unlimited' policy in any way? It's nearly what we have at every company now: a company vacation policy.

No, instead I'd advise setting a vacation minimum ("Everybody has to chill for 2 weeks minimum!"), then saying "take more if family contingencies come up" such as debate tournaments, sick parent etc.

will specifically target those who install power generation systems on their property and sell the excess energy back to the grid.

Misleading title. They want to tax people who want to sell the solar energy back into the grid , since joe six pack has to rely on other people's equipment to transmit the energy he captured on his roof. Also there is the issue of joe synchronising his output with whatever is coming down the line from the normal generators.

Maybe it shouldn't be a tax, maybe a fee paid to whoever owns the power infrastructure.
> I'll go through it almost as fast as the demo, ex-knotty wood.

Yes, with a lot more effort. Did you see how lightly he was swinging it for the inner splits? Other commenters talking about the extreme accuracy, but that's easier when you are hitting it so lightly.

Look, I don't regularly split wood, but I've spent several summers splitting wood before. And I've split unseasoned gnarly pine with a wedge and sledge. I am not completely ignorant on the subject.

So my question is why you dismiss it outright just because the demo uses favorable wood? Is it really wise to assume it's just a gimmick before you even tried it?
Cool idea. But the engineering seems fixated on mechanically hooking everything together with heavy frameworks, even having cargo building where arriving pods get racked.

Turns out space is big; things don't go anywhere if you just put them nearby. So no need to have buildings to store them.

And thousands of independently-operating solar cells would work as well as a big rigid frame. Why not have each cell in a swarm beam its energy to a single large transmission facility? No need to wire-and-bolt them together.

Probably its improvements in compute power that made this inconceivable decades ago. But now it seems obvious.
Clearly it works very, very well on some wood - the video proves that. So it deserves a place in my tool rack in the shed.

Or it would, if it didn't cost hundreds of dollars! Maybe I'll make my own in the shop.

I consider it a "learning to walk before running" type of thing. It may not be interesting to a lot of beginners, many of which probably want to immediately start doing something "interesting", but these are the fundamental basics that anyone claiming to have a CS degree should know.

Starting with higher-level languages tends to breed more misconceptions, because the students get used to seeing things "seem to work like this", and having only a vague, superficial understanding, it is much harder to unlearn these than to learn the truth in the beginning.

It's also not as if things like logic, data representation, and the sequential nature of programs don't matter at higher levels --- whenever one uses conditional statements and loops, a good grasp of boolean logic is essential. Why numbers have a finite range, floating point values aren't exact, etc. all depend on knowing how data is represented. Not knowing these things will at best make it difficult to reason about code, and increase the chance of introducing bugs; at worst, it can lead to security flaws.
