Everything ultimately manifests as a restriction on the set of assembler instruction series you are permitted to execute. A GOTO that is restricted from leaping outside of its local scope is a limitation. A language with no GOTO is even more limited. A language that only permits tail calls is yet more limited. You don't have GOTO unless you have a full, unrestricted JMP, and if all your language has are tail calls, you do not have a full unrestricted JMP. If you have "pointers" but can't perform arithmetic on them, you don't really have "pointers".

All of these things are restrictions, as well as features. The idea that "features == more power" is not accurate... features and power have a complicated relationship, the moreso since there's more than one useful definition of power, but they are almost no matter what neither strictly in opposition, nor strictly working together. But pretty much every useful high level feature is some restriction on what code sequences you can cause to run with the language, together with something built on top of that restriction that would be either harder or less safe without the restriction.

Certain topics are taboo like Gamergate or Sexisim in STEM.

They lead to flamewars and bring in trolls.

Sure we all want equal pay for equal work and more diversity in STEM, but these sexist issues just bring in the SJW trolls and then the topic goes from bad to worse.

It is something that shouldn't be discussed on Hacker News, because it is more political than technical.
With the caveat that at the tech level required to launch such an attack, destruction of one's home planet would constitute something closer to vandalism of a historic site than destruction of one's species.

Of course, if you're thinking of a scenario where aliens at that tech level launch such an attack against us 21st-century humans, yes, we'd be toast.

You don't need to expose a pointer datatype to offer a reference equality check operation. Java, JavaScript, C#, etc, all do reference equality by default for user-defined classes.

...and the governments will then be virtually the only ones who can still inspect traffic, since they can still get CAs to issue certificates for them. Moving everything to HTTPS dependent upon CAs only makes the whole Internet more centralised, which is horrible for privacy and anonymity.

They will all say it's "for your security", and arguably having this centralised root of trust does lower risk of attacks from random groups, but at the same time it's allowing them more power. To CAs and governments, a lot of things around encryption seem to be oriented in the direction of "if we don't have control over it, we disapprove." Self-signed certs are only one example of this; see all the other issues surrounding mobile device encryption. It's only good encryption to them if they are the ones in control of it.

Quite frankly, to me it seems random hacker groups have a lower chance of cooperating and tracking you in the same way that governments can.

I believe the relevant quote in this situation is again the classic "those who give up freedom for security deserve neither."
What sites are disabling TLS 1.0? According to the SSL Pulse report[1] it's the most-supported version of SSL/TLS by far (99.7% support). TLS 1.1 and 1.2 are disabled by default in older versions of Internet Explorer so not supporting 1.0 would lose those viewers which is enough reason to keep it enabled for almost all HTTPS sites.

OP here. Excited to start showing this stuff to the world. We think identity and login are really broken today, especially on devices that are becoming smarter (mobile, TV, etc.), and we are hoping to provide a solution that lets you take an identity with you wherever you want/need it.

Since we're not a social network, we can avoid a lot of the risk and confusion about how to use the product without accidentally sharing too much information, and really focus on building a first-class identity product.

We're happy to answer questions if you have them. There's more to come, soon!

"Claiming you can't have a perfect circle because pi is irrational makes no sense. The physical world isn't built on the decimal system."

Irrationality does not depend on the base it is expressed in. It means that a number can not be expressed as a ratio of two integers. Even if you declare yourself to be in "base pi", in which pi is "10" (if it is anything at all, irrational bases get... weird. or, if you prefer, "fun"), pi is still irrational.

Edit a few seconds later: On a whim, look what pops up as the first hit in Google for "irrational base": http://en.wikipedia.org/wiki/Golden_ratio_base Synchronicity strikes again, sorta.

I think the negative reaction is more due to the fact that it doesn't seem to be a well thought-out opinion. There are all sorts of bad things you can say about JavaScript, but I'm not sure that "It permits code obfuscation" makes sense to include on the list.
> The cert problem is a fixable problem, but it's not fixable while unencrypted HTTP exists.

Sure it is. Whether or not HTTP exists has zero bearing on solutions to the cert problem; the cert problem is independent of the unencrypted problem (whereas the unencrypted problem is dependent on the cert problem, since the cert problem is precisely why the unencrypted problem currently exists).

Over building renewables and transport capacity would probably be worse than the status quo in terms of cost and carbon generation. Peak power, which is dictated by people's general schedule, dictates both the generation and capacity requirements. It doesn't make any sense to over build renewables when everyone is using power after the sun went down or when you can't control when the wind blows. In ERCOT, (Texas) the price of electricity overnight (when the wind is blowing) often goes negative meaning that the power producer pays you to use electricity.

This is why the next generation of battery technology is going to be so groundbreaking. It will allow batteries to become more economical feasible both on a small and large scale. It simply cause renewables to become more societally efficient.

> But labeling it as "as secure as a self-signed cert" when a self-signed certificate provide no authentication (or an unpractical one at best) is uncalled for.

It's perfectly called for. The CA system is based on arbitrary trust. An actually-effective system should not rely on trust at all.

Even something like what Namecoin does - using a Bitcoin-style blockchain as a public ledger, but for SSL certs instead of DNS entries - would be a massive step in the right direction in comparison to the current CA system.
Kaspersky says that if you decide to write or download a program that executes arbitrary bytecode written to the blockchain it would be possible for somebody to put malicious bytecode on the blockchain that you could then execute if you decided to point to those transactions.

Fortunately there's a fix - don't do that. Nobody does that.
Out of interest, and I've done no research into this yet, how is your SQL editor/code complete working? Does it use SQLite's engine itself to get the AST or some such?
Yes, that's how Unicorn works. But HAProxy isn't designed to inherit another process's current state (see this other comment: https://news.ycombinator.com/item?id=9371064), and it's probably quite complicated and error-prone.

If you're going down that route, it's probably much easier to write the code required to simply re-read the config and apply a diff to the internal data structures.
It's the satirization of the idea that 'mother nature' is some kind of right thinking steward of life on this planet that you commonly find amongst people who call fossil fuels meth.

On its own, probably not; web-of-trust is one of those things about PGP that was awesome on paper, but in practice ended up being a significant pain point.

A cryptographic ledger, on the other hand (think Namecoin), would probably be at least slightly more effective; it would effectively confer the same benefits (decentralized registration authority) without the logistical nightmare of a web-of-trust.
The recent articles on Artificial Superintelligence have got me thinking about interstellar MAD. It seems that once you have ASI you really have the capability to do anything within the laws of physics because if there's anything you don't know how to do, you just add intelligence until you do. If so, it seems that primitive civilizations can become enormous, exponentially expanding threats to established civilizations in relatively no time at all, and in fact they are extremely vulnerable if they choose not to, not only to established players but to any new ones that come along.

A bit closer to the original source: https://securelist.com/blog/research/69488/blockchain-techno... (can't see a paper or slides associated with the talk at BlackHat Asia, there is a very short video demonstration included).

As far as I can tell, the point of this demonstration is that you can store bytes representing a piece of malware in the blockchain. That is, just treat the blockchain as a storage medium for your malware code, since it is in the end a distributed database. You still need some other piece of malware to read this bytes and execute them, which makes this not really a "vulnerability". As far as I can tell it's more a case of "append-only publicly-writable distributed DB operating as intended".

I could be missing something, though...
If we forget about the percentages they own and focus on the value of their stock we see that their stock goes likes this:

I suspect that the founder ownership percentages are actually lower than you've suggested and that right now they own somewhere around 20 to 30% which is still valued at $110m to $165m.

It seems like this would still have one of the issues SSL has where it's easy to get wrong and then it's no better than not having it, except that people think they're safe. E.g. use a weak hash function and someone can write a malicious script that hashes to the same value.
Having multiple code generators is not mutually exclusive, and this effort does not mean MSFT is ditching any existing AOT (or for that matter JIT) compiler projects.

One of LLILC's major objective is give the community an MSIL frontend for LLVM.

This allows a JIT or an AOT compiler to take any C# program written for the .NET Core class libraries to run on any platform that CoreCLR can be ported to and that LLVM will target.
The QR code on the sign accomplishes essentially the same thing.

While the solar wind gets stronger closer to the sun, it's an r-square law that balances the r-squared force of gravity. Fun fact: If a solar sail could be in a fixed position at Mercury orbit then it could also be in fixed position a Neptune orbit.

Quoting from http://en.wikipedia.org/wiki/Solar_sail, the "total force exerted on an 800 by 800 meter solar sail, for example, is about 5 newtons (1.1 lbf) at Earth's distance from the Sun".

The Orion space capsule is ~25 sq meters. I'll round that up to 100 sq meters (I'm being generous), giving a breaking force of 5/64 N on the waste barge.

The capsule mass is 20 tons. Assuming the waste barge were the same mass (I'm being generous) gives a solar gravitational force in Earth orbit of 120 newtons. This far exceeds the push from solar wind, even with wildly optimistic numbers. (Note: there's some 50,000 tons of high-level nuclear waste in the US.)

So no, you couldn't lose a lot of velocity just braking against the solar wind. Not unless you've also developed effective solar sail technology.

Like Synroc I came here for my undergraduate studies and work for a company in SF. I have no intention of leaving unless i am forced to do so.

I spent 5 (4 years of school + 1 year OPT) amazing years in this country and made many american friends, dated american girls lived in two of the most vibrant american cities (SF and NYC) and really adjusted to the American life style. It really hurts to be forced out after experiencing all these great memories. I deserve to stay here..

And now I am sitting in front of my computer refreshing by browser every 30 seconds waiting for an email from my companies legal department.

A bi-elliptic transfer is used for transferring between two orbits around the same body. In some situations, this is more efficient than a straightforward Hohmann transfer, at the cost of taking much, much longer.

For a Hohmann transfer, you reduce the ship's orbital velocity relative to the sun, reducing the orbit's perihelion to somewhere inside the sun. That requires cancelling out almost all of the Earth's orbital velocity.

For a bi-elliptic transfer, you first increase the ship's orbital velocity relative to the sun, increasing the orbit's aphelion to somewhere in the outer solar system. That's your first Hohmann transfer, going apparently the wrong direction, but requires less than 40% as much energy as dropping it into the sun did. Then, at aphelion, when the ship's orbital velocity is lowest, you reduce the ship's orbital velocity to drop it's perihelion inside the sun. From that far out, and at such an eccentric orbit, that requires only a fraction of the energy it did from Earth's orbit.

The entire manuever, potentially, could be far more efficient than a direct transfer. It just takes far longer, and if the ship fails to make the second maneuver, it'll be left in an orbit that crosses Earth's orbit.
Well yes, it could be fuel in the future.

But at current in the US it is stored in holding pools all over the country. None of those are getting any larger, although they are frequently reworked to allow better use of the volume available.

Very little of it is 'weapons grade' and not many people have access to the equipment to weaponize it into a nuclear weapon. But turning any of it into a dirty bomb is trivial if you can steal it.

There is also the problem of accidents, why by definition are unavoidable.

So, you really do want to get rid of the fuel. Launching it into space is impractical. But it should be stored in a difficult to access facility where the chance of it escaping is minimal. The US federal government collected billions for the construction of such a facility, but it was never completed. So as a result, we have fuel scattered all over the US.

Absolutely wrong. Renewables are pretty much cost competitive without subsidies now. What you are saying may have been true 5 or 10 years ago but is not any longer.

A tax on carbon would just be a nudge over an already existing tipping point. It would turn a cost/benefit analysis that could go either way into a no brainer. That's what we want.

I don't want to spoil it for future readers, but the basic premise is: the solution to the Fermi paradox is that intelligent life is fairly common in the galaxy, but instead of nuking themselves off, most species that achieve complex technology wreak their native planet's environment and trigger a civilization collapse.

Later on, some species are able to bounce back and rebuild a somewhat advanced civilization, but the mix of taboos against 'rapid growth' and lack of highly concentrated energy sources make those civilizations much more conservative, and the common memes of Scifi (e.g. the "technology indistinguishable from magic" thing) are never realized.

Think a sort of cross over between Dune and the Hunger Games.

The golden ratio is easy to demystify for journos or non-designers observing the continuos wave of photoshopped crap trying to $ fit --force the spiral inside random images/works. But designers of school (industrial, architectural, engineering etc), know that it has been used for ages. It's there in the books, even in ancient books, period. And it is just another tool for achieving pleasant proportion and cadence.

Design has been prostituted lately, specially with the boom in the software industry, and seems like fitting the spiral in works that weren't built using the tool properly in the first place are destroying its real utility/credibility as design pattern. Fact is that fibonacci (as a mathematical pattern) is useful and can actually be found in several fields from the stock market [0] to physics [1][2]... so it's not just a "design thing".

Is it the "holy number" that many people praise in order to sell their designs? definitely not...

Is it useful as a design tool and could it be an unexplored and practical numerical constant? definitely yes...
