> I think the opposite? Ie most problems are far more intractable using string theory

It's a better framework for some problems as a model of other (comparatively mundane) quantum phenomena. But yes, generally you're far better off sticking with QFT or GR separately for observable physics.

In theory, future technology will be able to observe some of the regimes string theory (and other attempts at unification) throw at us. But this of course requires experimenting in places where quantum and specifically general relativistic effects (QFT already incorporates special relativity) are both strong. We don't really have any places where we can observe distinctly GR effects that aren't on some sort of literally astronomical scale (the closest we can go is Earth's orbit with timing for satellites). Since QM likes to stick with the small, this puts us in a real bind until we can do something crazy energy-wise.

> It seems like there's some lack of imagination here, like physics is "done", there's nothing more to answer

Physics isn't more done than any of the other sciences: there's an incredible breadth of active research that makes up most of the fields of physics (condensed matter, quantum information, atomic/molecular/optic). We might have a formulation of most of the fundamental ground rules, but then so do biologists and chemists by the same token. I think the unofficial motto of condensed matter physics sums up the opportunity for exploration pretty clearly: "More is different".
Monorails typically use rubber wheels, which DO have a lot of advantages (maximum grade, sound, stopping distance), but I'm also unclear why that couldn't be applied to birails. Monorails might also have a smaller turn radius?

Ultimately I feel like the problem with monorail is that public transit is primarily a political, not technological, phenomena, and so while there might be a good idea in monorails, or iterations where it could be combined with birails to make something truly technologically superior, but it just doesn't matter.
What are we talking about with "philosophy"? And what is "physics"? Are physicists featureless spheres unable to be "philosophers"? https://www.edge.org/conversation/a-philosophy-of-physics

What "philosophers" are we talking about here? Lakatos? Chomsky? Newton? Logicians? Or do we have some composite postmodern blowhard in mind? (Like any industry's products, philosophy's product quality varies with factors like producer. So specifics are important.)

There's a bias in physics culture against philosophy. (It's no doubt elsewhere too, but very apparent in physics.) But fortunately, there's many exceptions who like to take a step back and think about what they're doing.
That's basically the whole point of the scientific method and that's how it evolved during the Renaissance when we went from philosophers and logic to scientists and experimental data. Few scientists have the delusion that our theories are anything but crude aproximations of the real world, each requiring extensive caveats and each with its own domain, outside of which they're useless (i.e. Newtonian mechanics is useless for high velocities and relativity is useless at the quantum level).
Any chance you plan on supporting UI's for Unity3d?
> To be very clear, I don't actually believe this is what happened, but I quite like the idea...

I think that's the basic difference between a conspiracy crackpot[1] and a novelist.

1) sadly, as I read more history, a lot more of the "crackpot" than I am comfortable with was actually the truth. People do some strange things for some very odd reasons with some seriously poor logistic skills.
I think the 'Asooka' is aware of this, and was not offering advice. Rather, he was proposing that the world would be simpler if the specs were changed so that signed addition never resulted in undefined behavior. In this simpler counterfactual world, his test would work. In our current easier to optimize world, it would not.
It's almost as if autism is a spectrum...
That's my thinking too. When trying to define what philosophy is, I have settled on this: Philosophy is the reasoning about poorly defined things, using similarly fuzzy steps. This is not a value judgement.

Once we get a better grip on an area, then, finding more proper definitions for its concepts, we branch it off as a subject of its own.
Now it's "your house doesn't matter, because you'll be spending nights and weekends in the office. But it's OK, we have free meals and beanbag chairs."
Yeah, I like it too :-) Philosophy has surely delivered unicorns: Mathematics, Physics, Biology, Chemistry, Computer Science! The question is, can Philosophy deliver another one?
Probably not. However, an OS is a tool, and your tools inevitably shape the way you view what you are working on. I'm going to revise my comment to tone it down, but the fact remains that network-native multiuser OSes (Unix, Plan9) encourage a very different view of the world than desktop-centric single-user OSes (Windows, in particular). That's not really something that needs further explanation if you've seriously used both, and the differences were much, much starker in the late 90s.
I would imagine that people would think that's a serious waste of money given the odds. Of course after it happens, someone will go "See!!!".
There are two main advancements beyond "classic" honeypots:

1. Honeypots are easy to fingerprint (see our blackhat talk, https://www.youtube.com/watch?v=Pjvr25lMKSY )

2. Most honeypots just "sit on the network", waiting to be scanned. By using breadcrumbs (AKA honeytokens) as part of deception stories you're actively hunting the attackers in the network, by influencing their decision process.

> The reason Aristotle didn't get anywhere in the Metaphysics was partly that he set off with contradictory aims: to explore the most abstract ideas, guided by the assumption that they were useless.

Alchemy is a good example. Alchemists dabbled in chemisty but they also took for granted that chemistry has deep symbolic and semantic meaning. Figure it out and chemistry will crack.

It turned out to not be the case, time after time.

There's no inherent meaning in how substances interact. There are laws, they're consistent but devoid of any meaning, on human level.

That's why I'm deeply scetical towards any New Age-style ideas.

Because negotiations (thus salary negotiations) aren't about spreading disagreement, but about making an agreement with which both sides can cope.

Thus if you add the personality trait "aggressive and disagreeable" to a typical aspie, you'll get a termination of negotiation instead of a strongly suboptimal (for the aspie) negotiation result.
> The problem with physics today is rationalism - constructing theories with only partial reference to experimental data. Some fields, like psychology, have the opposite problem - empiricism - where they accumulate countless statistical correlations but fail to integrate them into consistent theories.

"Rationalism" is still serving us very well in pretty much every other field of physics except unification theories. We're still coming up with great new theoretical models based on working with the laws we have, sometimes driven by the need to explain existing experimental results and sometimes to look for new places to do fruitful experiments. There's a much better balance between the two for physics as a whole than you're making it out to be.

I'm not sure how wrapping in Ayn Rand's theories with all their politics is going to streamline physics.
Avoiding undefined behavior is good, and a good programmer tries to avoid undefined behavior. The fallacy is that there exists a population of C and C++ programmers who are skilled enough to always recognize and avoid undefined behavior. While you could define "a good programmer" as one who always recognizes and avoids undefined behavior, the unhelpful result would be concluding that very few good C or C++ programmers exist, possibly none.
Well, sure. How much depends on what you're working with. Adding a single design or code review step in an otherwise feature-driven company is shown to knock out all kinds of issues. DAO came down pretty quickly. That much time for review with some bug bounties might have prevented some issues it had. They could still be developing on it in the process. Just not putting money in for real until it passed what peer review they could get.

Of course, it's an example where there's all kinds of potential for problems that could take a serious amount of time to work out. Can't keep innovation pace high with something like that plus ensure quality. So, the trick is usually to leverage as much proven stuff in one's innovation as possible. Easy to do with software at least.
I feel if you haven't figured out where "home" is, you would be a lot more open to the idea of moving. But as soon as you add family to the mix, "home" becomes more defined.

When you're younger, you switch jobs a lot more often to figure out what you want to do and to try something new. I wouldn't be surprised if that extended into moving more often. E.g. I want to try city living, then suburb living, etc.

Funny thing about the Bay Area, though, is that it can get hard to move around because if you've lived here for more than a couple years, you are now renting or owning a place so cheap (in comparison to market prices) that you can't justify moving.
A 250 mile circle around NYC has a lot of stuff. The Adirondocks, various flavors of Atlantic shore stuff, etc. Lack of things to do outside isn't a reason that holds water :)

To me, California is where you go if you hate winter and like outdoorsy stuff. The unique Californy things are unbelievable, but the reality is most people are living in generic developments and driving to generic office parks, and doing very little else. You can do that in Toledo.

"I am surrounded by people who like to spend our free time outside."

Spending free time outside pretty much defines the bay area. We're here because it's always sunny and not too hot so we can spend our time outside.
Queasy nerds make SJWs uncomfortable because they are perceived as much more likely to display shockingly inappropriate sexual behavior. Since women have the right not to fear for their lives or chastity, the reasoning goes, they have the right not to have any contact with queasy nerds, and so they must be expunged from the places in society where they nest (computing, gaming) in order to create "safe spaces" for women.

This is also a subtext in the upcoming 2016 Ghostbusters film: the villain is a queasy nerd who summons ghosts to Manhattan as revenge for getting the mockery and rejection he deserved; so it is up to the Empowered Womyn Ghostbusters to exorcise him so NYC can become a safe space again.

Hey, you're supposed to incorrectly call it sharing economy. Hmm... somebody sharing a car with you... somebody driving you around... sound like it's the same thing... Offering a service is obviously the same as offering access to a resource... except it's not so why do online newspapers call it sharing economy? Do they want to show off their lack of competence that much?
> Because those crimes are (for anything above the baseline for people in general at the same poverty levels) are results of centuries of being abused, held down and denied opportunities.

Yet no matter where you look on this planet, no matter what the history of that location is, no matter how far back in history you go, the pattern (of violence such as murder and rape) stays the same - and even more so when those places are absent of the other races/groups.
Cleaner, more elegant, and wrong
Yeah, many of the 'popular' discussions of Quantum Mechanics that show up here on HN do often diverge well into philosophical directions and away from hard science.

It's true that science and philosophy did come from a common discipline (my undergrad uni originally had a Natural Philosophy dept that only became a physics department somewhere between 100-150 yrs ago).

Though I thought one of the physics professors when I was in grad school said it best : "Physics is philosophy with integrals".
Seeing as Cert Pinning bypassing doesn't currently work with XPosed on Android versions greater than 4.2.2, I'm not so sure about that.

Google has offices everywhere - New York, London, Dublin... who knows where else (well, Google do). I wouldn't say you have to be in the Bay Area in order to work for companies like that.

In any case, I don't see why working for a company that is becoming increasingly profitable is a positive for me, unless I see significant dividends from it.

You're unlikely to get it there either.

Do there exist any good tools for identifying undefined behavior in C or C++ code? Compiler warnings are getting better, and "sanitizers" can catch undefined behavior that actually happens at runtime, but I still haven't found anything that consistently catches unwanted optimizations based on compiler assumptions of "no undefined behavior".

Stack (https://css.csail.mit.edu/stack/) is the best tool that I've found, and while it's a great start, it's extremely difficult to install, clumsy to use, doesn't appear to have been touched in years, and only catches a limited subset of constructs. Is there anything else out there? If not, is it because it's perceived as too difficult to do, or is it just not perceived as a need?
Hey all!

Originally this library existed as a module within https://github.com/AtheMathmo/rusty-machine but I've finally got around to separating this from the machine learning stuff.

Despite being around for a while it is definitely still an early stage library. I'm hoping that by separating it I can speed up development a little and pull in some people who care about the linear algebra and not so much machine learning.

I'd love to answer any questions about rulinalg or rusty-machine. I also welcome any feedback.
If you plan on doing that, it might be worth looking into a similar project that uses the XPosed framework to bypass certificate pinning at a low level:

https://github.com/iSECPartners/Android-SSL-TrustKiller

Although it only works with Android versions up to 4.2.2, due to limitations of the XPosed framework.
I disagree, I think it's a reflection of young people having different priorities to older ones. As you age you start caring about having space for children, good schools, etc etc. Life priorities change, and that's nothing new.

Thinks like the Andrew File System and Coda were actually developed to try and work around this, to provide resilience and allow one to have "soft" state in the presence of outages. The interest was not there, certainly not when most people were working on standalone Windows boxes or Macs, and didn't have any idea of the sort of power that was available in research labs via X and Ethernet.

It's a shame, because not only did research groups think about these issues, 20 solid years ago, but also several strong contenders for solutions were implemented. Society did not see the value in supporting further work on the projects and so the researchers moved on.

Pike is not an idiot. He is a pragmatist.
Not if the scientists are working on string theory. I'd rather have philosophers 100:1 in that case.

That's a bit silly. His perspective is that of someone who watched tractable solutions to the cached-state and resync/reconciliation problems be implemented and then marginalized, since no one at the time saw the point. Now, 20-30 years later, it's starting to dawn on people, and the response is essentially a kludge.

I'm disappointed, and I was never at Bell Labs. I imagine Pike is being diplomatic, to be honest. Research is incredibly frustrating when it depends so much on fashion.

Sun not adapting to market changes. Who wants a Solaris SPARC box if a X86 PC with Linux is cheaper?

Remember the network computer Sun made with Java OS that was supposed to take on Microsoft? Nobody wanted one.
One way is to probe them indirectly. For example, string cosmology makes testable predictions (verifiable by observation, e.g. of the CMB). Conceivably, evidence could be found of something that happened in the early universe that is most easily explained within the string theory.
I think that this is pretty interesting. It seems like Sun couldn't keep up with Linux. but still screw java adware
Theoretically, yes. If you set up billions (maybe even trillions) of powered electromagnets in a stable, very precise orbit around the sun and injected particles into the loop. However, this is hugely impractical and the sources of error would be huge. Electromagnet misalignments (with the error compounding over stellar distances), stray asteroids and comets, cosmic rays, etc would all effect the particle beam.
There are pros and cons.

Pros to comingling:

1. Makes customers happier to get their item sooner

2. You don't need to label your items, which either saves you time or saves you the 20 cents per item fee Amazon charges

3. Your items get processed quicker. If your items are in between warehouses, they can still be "shipped" to the customer.

Cons:

1. Counterfeit possibility. This varies by item. Amazon claims to track which seller inventory was sold from.

2. Bad returns, may hurt your account or require time to deal with.

Basically sometimes it makes sense and sometimes it doesn't. I use a prep center which labels for me, and when I send in items myself I have Amazon label them.
If they wanted to capitalize on this some more they should add an option to turn a location into a pokestop.

Or, in the event that a connection was lacking, local state would be maintained only as long as required to allow usable work to get done. Google "coda" or "intermezzo" or "andrew file system". You might be surprised how many people worked on these things. I was, and I worked on some of them.

Somewhat, but not wholly, tangential: when I read research papers, one of the first things I do is to look at how old their oldest references are. If the references are less than 50 years old, one of two things is usually true (sometimes 0, rarely 2, but usually 1):

1) The field is quite new (e.g. CRISPR-Cfp1 gene editing)

2) The authors don't have experienced mentors to guide them through the enormous literature, particularly in mathematics, physics, and chemistry.

It is very rare to see Option 1 in practice. It is incredibly rare for someone of Pike's experience to fall into category 2. This interview is not a research paper; nonetheless, Pike did quite a bit of distributed systems research and is familiar with all of what I mentioned. Networks weren't always ubiquitous or reliable, but the fundamental idea of efficient compute resource sharing has always been attractive enough to view this as a complication rather than a deal-breaker.
In my opinion Copenhagen is just as much philosophy as many-worlds, but I think many-worlds is at least more elegant.
Thanks! If you come up with an example I'd love to see it.

Generally, even though `\w` in Rust's regex library supports Unicode, it shouldn't result in a slow-down compared with the non-Unicode `\w`, assuming you're using find_iter. (Of course, Unicode support isn't free, but the primary cost here is memory and compile time, not matching performance.)

If you were indeed emitting `String` (a new allocation for every match) instead of `&str`, then that could certainly be a possible explanation for the slow down.
And calling philosophy navel-gazing is navel-gazing.

The philosophy of information is a great example of where it's incredibly important [1]. I seriously, seriously doubt that information theory would have come about without many of the philosophical underpinnings that came before it. It's not just about structure.

Hm i wonder why someone thought there is some invisible, unobservable dark matter instead connecting gravitational waves with super massive black holes in center of every galactic.
