which is, ironically, the kind of Big Government bullshit the right-wing in this country claims to want less of. it's hypocritical.
The appendix relates this +/1 (Z2) phase factor to the so called "cat states" of the spin system. There are deeper ways to understand its more general consequences through a type of math called cohomology theory but it's not possible to make general statements about time per se. Now, if you're interested in how information moves in spin systems with respect to time I urge you to explore the fascinating topic of Lieb-Robinson bounds, but I feel like this overview might boil down for you what the paper is trying to accomplish more idiomatically: http://www.condmatjournalclub.org/jccm-content/uploads/2016/...

There will be no strike at anyones achilles heel, at least not if we are talking about mayor world powers like the US, Russia and China.

The most any one of these powers will do (and all of them do it) is trying to subvert and destroy weak governments that are friendly to the adversary.

There's not even a chance that one power might try to pit the two others against each other (I'm talking about a real war) because all of them are guaranteed to wipe out all of the others if the survival of their own state is sufficiently threatened.

The reasoning for this goes something like this: If we are destroyed and only one superpower survives this (because they didn't take part in it) they'd be in a position to dominate all of what remains. Very cynical but that's how MAD works.

Even Israel which is much weaker than any of those three has a similar deterrence strategy. It entails striking the West, even if they were overrun by Arabs, not Western powers.

I don't like how this all works (I'm not a Sociopath) but it seems to have been very effective over the last decades because the actors were all rational.

The reason why Muslim countries acquiring WMD's is so much more heavily opposed is that many strategists do believe that their ideology could threaten MAD. It is not inconceivable that some of these governments could launch an all out attack if they had the capability believing that they will all go to heaven for taking out what they perceive to be "the great Satan".

Even if the mutation was part of the original soup of bacteria, the process in the video still shows evolution. Either at time=0 or some point in the future, a strain of bacteria was more fit to survive and produce viable offspring than the others that died off in the presence of the antibiotic doses.
What would be really powerfull is a dual markup/WYSIWYG UI, like WPF in visual studio

WordPerfect had this in the '80s. It's a conventional word processor, but you could press the "Reveal Codes" function key and get a split-screen. The lower half would show all the markup. You could see and delete a tag explictly, and its matching one would also go away. Though of course, the markup was not indented.

My mother, -- a secretary -- used it all the time. But when she met other secretaries who came from an MS-Word backround, they hated the very existence of the feature. I think the last few editions of WP removed it (in order to cargo cult Word?).

Then they went out of business.
I'm sorry, would you care to answer the question of how many times you've put on a seatbelt versus how many times you've BASE jumped? For me, that ratio is whatever 50000 divided by zero is.

Cost of installation is by no means the only factor or cost in making a safety feature. In another comment, you appeal to the many number of paratroopers who have jumped out of planes as prof that it can be cost-effectively, as if the cost of a paratrooper's jump could be reduced to the cost of a parachute.
Democracy is how we determine what laws to pass. Universal rights are how we determine if a law is just. Just as we have a universal right to not be enslaved, we have a universal right to not have our private property and privacy violated, and an income or sales tax does both.

>I also don't understand the distinction for private trade, in that without a functioning government to support a marketplace, such trade would not exist.

Private trade refers to trade amongst exclusively private entities, as opposed to trade amongst several entities, one or more of which are public (government).

Your speculation that private trade wouldn't exist without services rendered by government, even if it were accurate, would not disqualify trade amongst private parties as private.

> Reminder that in America high voter turnout almost always favors Democrats

Wrong; the effect is mixed. http://www.factcheck.org/2016/06/sanders-shaky-turnout-claim...

> Republicans are very good at gerrymandering and taking control of state governments

Both sides gerrymander as much as possible. But Democratic votes already naturally clump geographically in a state, causing them to say, win 90% in an urban district and loose 40% in a bunch of others. https://www.bloomberg.com/view/articles/2014-09-08/why-democ...

Most analyses just look at total votes and resultant state representation, while forgetting that most of the effect is a natural consequence of Democratic geopolitics, rather than some Republican superiority in gerrymandering acumen.

> They [Republicans] use this power to restrict voting rather than make it easier

Maybe the media favors that story in the past 12 months, but that is not a trend.

The Voting Rights Act had better support by Republicans than by Democrats. In fact, the Democratic majority had fillibustered the bill in the Senate until the Republican minority leader stepped in.

Remember the voting rights case where a federal court concluded there was "a systematic and deliberate attempt to reduce black political opportunity. Such an attempt is plainly unconstitutional. It replaces a system in which blacks could and did succeed, with one in which they almost certainly cannot...The inference of racial motivation is inescapable."

Whom did that case convict? The original President Clinton.

Both sides play these dumb games.

> voter fraud, which statistically doesn't actually occur in the first place.

Probably. While it's often repeated that there are very few "credible" cases of voter fraud, that doesn't necessarily say much.

Remember that George Bush won the presidency in 2000 by 0.009% of the Florida vote. The Democrats were sure counting the beans then.

The fleet of Tesla cars on road is an advantage that Uber and Lyft have over Google. They can deploy cars with a lot of sensors on the road AND make money off of it for the most part!

If data is the differentiating factor in this game, Google has less of it! Which is interesting position for Google to be at!
Got your idea? Great, now you need write it up and tell everyone about it so you can find your teammates and supporters

Reads to me as: got an idea? Form a political party.

I predict internal politics will destroy this idea because any group that believes it is immune to politics is already infected but in denial.

We can't escape politics. It's what we do. It's the fundamental fractured structure of the human experience.

We need politics because it's the best and least harmless place to put those criminals we call politicians.

Also, amusing the domain is .camp. The word camp shares the same origins as the German word kamf which means to struggle. Yep, politics sure is a struggle.

You made an emotional argument that seems angry at a certain group ("Silicon Valley kids").

However, the work that will not be done by those people who can do it but don't want to will still need to be done. The solution will then be to hire people at higher wages.

But since these higher wages are not a result of increased productivity, the employers won't be able to sell more. The result is that prices will go up, generating price inflation. And we know inflation is the worst of all taxes, as it affects the poorest the most.

In the long run, the money received via BI won't be able to sustain the "comfortable living" that it was supposed to.
It took me a huge time to get through Rendezvous with Rama. (I stopped reading and then finished it almost an year later). Even though it is a pretty short book. For me, it just too much hard-SF with none of the character development. The ending doesn't help with that either.

But then, I didn't like Eon either (Greg Bear), so maybe hard-SF isn't really for me.
I see everyone talking about Andrew Ng's ML course and having some difficulty with octave. Why is no one trying the new ML with Python series by UW on Coursera? It seems pretty well structured.
This is obviously valuable work in general, because a lot of people don't read science fiction, blogs, dream about technology, etc. I question how valuable this is to the HN audience who spends much of their time thinking about these topics, though. I spotted nothing that stood out from a skim through this article. Maybe the full report has more, but most of what it covers seems to be things along the lines of "who will have liability when a self-driving car kills someone?"...

Thanks for the constructive critique - fixed suggested points.
It's actually a resource for another project but haven't found a recent list of brands/models.
Maybe so, I'm not privy to their methods, but I wouldn't be surprised that they use, e.g. statistical models, computed on machines, to help them figure out whether or not to look more closely at a given taxpayer.

But however unpleasant it may be, an audit is not a punishment. (Someone is abusing their power if so.) Not anymore than being selected for jury duty is a punishment.

Also, you used the word "probabilistically". We should not be assigning sentences based on the roll of a die, eh?

Insurance companies use machines and statistical models to set rates. But they also have strong feedback to improve accuracy. They lose money if they get it wrong.

Here we are talking about judgement.

I know far too much about computers to ever credit the idea that these machines can replace a human judge. The people who have put these things into practice are deeply incompetent and should be voted out of office and replaced by folks who won't devolve to crude machine-worship.
It's the tooling, not the size of the data. Using "big data ecosystem" tools allows you to use all kinds of useful things like Airflow for pipeline processing, Presto to query the data, Spark for enrichment and machine learning etc... all of that without moving the data, which simplifies greatly metadata management which has to be done if you're serious about things like data provenance and quality.
Ask HN: Which language(s) should I learn to do one-man projects and earn money?

2) I don't intend to work for other startups/companies, just want to build my own projects and monetize them.

3) I like iOS/android programming, but I'd need to learn Swift+Java for both, and cross-platform solutions don't seem alright.

4) I also like web-apps, but I hate JS, and frankly, don't like any imperative lang for backend (python, ruby, ...)

Yes, I think we agree on a lot of this. Where we seem to disagree is on the prospects for a "silver bullet". As much respect as I have for Fred Brooks, I have always thought he was too quick to dismiss the potential of AI (though admittedly, when he first wrote that essay, AI was much better known for its failures than its successes). In particular, this dismissive, oddly moralistic quote from Turski, that you've requoted, I think is absolute horseshit. (For one thing, I'd wager that the biotech people will actually solve the hair loss problem within the next 10 years. I sure hope so :-)

But we agree that it's essential to understand what has been proven to be impossible. There will be no algorithm (in the sense of an effective procedure that works on any input) for computing correctness of programs. Indeed, all the familiar tools of computer science are inadequate: languages, logics, indeed formalisms of any kind. They may all have roles to play, but none of them can be the silver bullet in and of itself. It is exactly as you say, that the breakthrough, if there is to be one, must come through empirical analysis of actual programs.

But we now live in a world where, at long last, a machine has beaten the world champion Go player. Many experts thought that wouldn't happen for decades. If we can do that, I think that means we are finally starting to have solutions to problems of perception and pattern-matching that have been stymieing us this whole time. I am very excited.

I probably came out sounding a little too combative at the beginning. I think you've written an excellent summary here (modulo the Turski quote :-), and I think it's kicked off a very interesting conversation. (Even Animats, I think, doesn't disagree with us as much as he/she initially appears to.)

> In my job, I formally specify and verify large, complex distributed systems.

I am actually working on a project to put some code where my mouth is: to build a reasoning system that uses AI and ML and learns to reason about programs. It's a long-term thing and I'm probably a couple of years from having anything to demo, but I'd love to learn more from you about the problems you encounter. Are you by any chance in Silicon Valley? If so, let's get together. My email is in my profile.
We don't hear much talk about quantum computing and AI, is this because general purpose QP is considered unrealistic? Another interesting aspect in the podcast is that "doctors can't be replaced because they are able to interact with a patient", yet boston dynamics have shown us some pretty interesting progress in robotics, and we have some pretty amazing imaging and recognition software. The final thing I find interesting that people often refute on is that there isn't access to a good training set on humanity to start to understand us, well, I'd suggest that the WWW is an good collection of human knowledge.

Fine, let's say the singularity could happen. How do you know what form it will take and thus how to prepare for it? We don't have any evidence or examples of artificial human intelligence or something beyond us. Everything we humans build falls apart, there is nothing remotely resembling self-perpetuation of any sort. Where is the evidence that tech can do this? This singularity talk sounds, at best, like imagining flying ships in the 14th century. It might happen. But we have a long, long way to go and we have no idea how it will work.

As an experienced wilderness traveler, I consider teaching people about the potential risks to be the responsible thing to do. It might scare them off but that's better than them getting hurt or worse.

Besides, in my opinion being aware of the risks, no matter how minor, is considerably less scary than not being aware of them. People who are prepared will be more at ease and as a result they will enjoy the activity more. We are not talking about taking a six-month course on wilderness survival. We're talking about having some basic knowledge and equipment, neither of which is expensive or time-consuming to acquire.
> Building one or two very beefy machines is 1000x faster, and a lot cheaper than a Hadoop setup.

You have a few petabytes of data and your working set is 50 TB. You put it on two machines. All your data is now on these SGI UV 3000s or whatever. You now need a bunch of experts because any machine failure is a critical data loss situation, and a throughput cliff situation. Took a fairly low-stakes situation (disk failure, let's say) and transformed it into the Mother of All Failures.

And then you've decided that next year your working set won't be over the max for the particular machine type you've decided on. What will you even do then? Sell this and get the new bigger machine? Hook them both up and run things in a distributed fashion?

And then there's the logistics of it all. You're going to use tooling to submit jobs on this machine, and there's got to be configurable process limits, job queues, easy scheduling and rescheduling, etc. etc.

I mean, I'm firmly in the camp that lots of problems are better solved on the giant 64 TB, 256 core machines, but you're selling an idea that has a lot of drawbacks.
My only major complain with the book is that very often it uses particle physics as hand-wavy magic to break any rules it wishes to, and that breaks suspension of disbelief for me.
> The Voting Rights Act had better support by Republicans than by Democrats. In fact, the Democratic majority had fillibustered the bill in the Senate until the Republican minority leader stepped in.

The Voting Rights Act was passed in 1965, which was before the Southern Strategy. After the Southern Strategy, the Voting Rights Act's requirement for majority-minority districts resulted in packing black voters into a fewer number of districts, which is a form of gerrymandering that benefits Republicans.

Here's a technical explanation.[1] But here's an example of triggering crystal formation in a supersaturated solution.[2] Classic high school chemistry experiment. Dropping a solid crystal into the supersaturated solution causes the whole liquid to turn into a solid in seconds.

That's the basis of single-crystal casting. The solidification process relies on operating very close to the melting point of the material. The idea is to create an alloy mixture that's ready to crystallize, then starting the process by dropping in a crystal and letting the liquid crystallize in a very controlled way. The heated zone is moved through the liquid, as in zone refining (or the solid is pulled from the heated zone, or gas cooling is used) so that the crystal growth takes place in only a narrow layer.

This is decades old, and one of the reasons jet engines last a long time now.

This is actually one of the great gaps in available tools. For camping, there are some pretty good crowd-sourced websites that will help you find boondocking spots; these are not necessarily the most beautiful (though reading reviews will often tell you if there's something amazing nearby to check out while camping). A lot of it is targeted to folks who can't afford to camp in RV parks or campgrounds, but wants to get out into the wild.

This one is probably the best for finding BLM and National Forest options for camping: https://freecampsites.net/

All Stays is OK, too, but has a lot of noise in the form of Walmart parking lots and rest areas and such, as well as commercial campgrounds, (which are also great if you live in an RV and need a place to park for the night on your way somewhere): http://www.allstays.com/Campgrounds/

I wish there were a really good website that combined all of my favorite things: Public lands, free/cheap camping, and beautiful or interesting scenery. But, I kinda piece together my travel itinerary once I know where I'm going; I'll google a bunch the day or two before I start driving. Usually I'll have a pretty good idea of the places I want to stop, and how long I want to stay, based on reviews and the information I've found. And, sometimes there are surprises. When I'm on my way places, I'll sometimes stop at all of the public sites along the way (as best I can figure out where they are), and camp at the ones I like the best.

I'd start with what you already know. Depending on the project, different languages will be a better fit.

If you are just starting out and are focusing on web development, I'd recommend JavaScript since all you need to get going is a browser and a text editor.
I would be. I would find it much more likely that the IRS uses some sort of much cruder algorithm in tax auditing, which is what is intended to detect fraud and appears to be non-functional at this point.
Some people have moral objections to voting. For example the Voluntaryists believe that all human action should be voluntary, and therefore refuse to compel people to vote, and also reject the institution of law itself.
