somewhat related, I live un Budapest which is quite full of homeless people.

There is a program by which they distribute a magazine[0], mainly about the homeless life, and in theory with articles written by them.

It's still a begging of sort, so not as good as a proper job, but I've always felt it was much more dignified than panhandling.
And from the other side, it gives you the idea that people handing out the newspaper are at least putting in some effort
rather than just sitting on the corner (not saying they'd do, just talking fo perception).

No, it means (local) Lorentz invariance violation (LIV) under the Standard Model Extension (SME) in curved spacetime.

In SME you write down an observer Lagrangian incorporating tensors, spinors, covariant derivatives, and so forth, and SME coefficients: L = L_gravity + L_SM + L_LIV + ... where SM is the Standard Model.

You can write down an L_LIV that is an extension of GR with or without torsion. The second you introduce nonvanishing torsion you are no longer in Riemann spacetime. Without torsion, however, you can keep yourself in a Lorentzian manifold and still introduce e.g. spontaneous (and thus preserving geometrical identities) Lorentz breaking in the L_LIV, as in Bumblebee models.

In General Relativity, Lorentz invariance is what you get when you put a metric with a signature of (-+++) or (+---) into the Einstein Field Equations and then look at the local isometries induced on the tangent spaces and find the O(3,1) group. But you could just as easily plug any signature into the EFEs - there's no mathematical restriction, and there are researchers who use all sorts of signatures (e.g. (+++++), which is manifestly not Lorentz invariant).
Fosh. Dude is a scumbag. You know that meeting he just put together for/with Trump, with all the tech. leaders, centered around tech. employment? You know, the one with people like Jeff Bezos, Larry Page, Sheryl Sandberg, Tim Cook, Elon Musk, Ginni Rometty, Brian Krzanich...and Alex Karp.

Hmm, let's see.

Amazon employs 250k+ people;
Alphabet employs 60k+;
Facebook employs 15k+;
Musk's companies employ 30k+;
IBM employs 350k+;
Intel employs 100k+;
...
Palantir employs around 2000, but Alex Karp got to go to that meeting. I wonder who Palantir's biggest shareholder is...hmm?

P.S. The meeting also had Satya Nadella (Microsoft), Chuck Robbins (Cisco), and Safra Catz (Oracle)..and all three of Trump's children - who took seats from companies like HP, Dell, all telecomms, Xerox, and more. Seriously: fuck Peter Thiel.
Fiction HN: Monthly Book Recommendations from HN
Hello Hacker News! I don't read enough fiction and I'd love to get your input on some good books, be it science fiction or otherwise, that have expanded your mind, made you think or that you think are a fantastic read.

Feel free to just add a title/author or even a short review.

Happy Christmas!
Where do I make that judgement? You're turning it around again. Read my comment, there is no judgement of people whatsoever, only the claim that you should not have kids if you're unable to enjoy the joy of others. Because otherwise, yes, they are likely to make you feel like you're subject to an 18 year prison sentence.

You were right if it would take a lot of resourses to make things fast. But most of the time it doesn't.

I made a lot of sites fast(er) in maybe 4 hours time. Yes, slow frameworks are slow so you cannot change that in 4 hours time. But most frameworks arent that slow.
My work involved: rewriting a slow query used on every page, changing PNGs to JPEG and reducing the resolution, moving an event that is fired on every DOM redraw, and so on.

And every single time I was just fixing someone's lazy programming.

Ofcourse I agree that there should be a limit to optimizations, but most of the time simple fixes will reduce seconds.
think you're commenting on the wrong article
It would be dangerous if everybody not poor wanted nothing to do with poor areas and poor people. All kinds of poverty counted. That is the direct route to segregated communities and cultures of poor and rich, as seen already many places, except that right now, in 2016, most know that there is "lesser" communities and cultures next to theirs, having experienced them themself. If the fortunate communities would shield themself from the "truth beyond the wall" for a long enough time, kids would grow up only hearing tales of these other cultures, and at last, not even hearing the tales anymore. Rich communities - or modern, as the would be called - would be tight bound around themself, governments would work to shield the truth from their citizens. A future that has been depicted by many a movie, many a tv show, for many a year.

It's horrible future, but a future to come if people dont "want nothing to do with it", it being the very reality that they have diced a 6 on, and somebody lesser fortunate being born beyond the wall has diced a 1 on, only guilty of having another mother and father.

Some say it's a future only distant in the eyes of the rich. I think that is, sadly, very much true.

Having all my photos in Google Photos feels like I have super powers. I've managed to find so many photos I was looking for without any specific search criteria I knew would work 100%. But Google Photos tends to do a pretty good job at finding them.

Seattle has a similar newspaper. The newspaper has licensed vendors, who buy the newspapers at a rate around $1 (I think it's $1.15) and sell for $2. The articles are written and edited by and for the homeless community, and cover all sorts of city business and activities from a unique perspective.

Damn iOS auto-correct...that was suppose to say "compatible".
I’m not trying to say it will go one way or another—just that the variables in the equation have all changed (expectations, the nature of access to the Internet, ubiquity, &c.), so results from several years ago are obsolete (I’d even call results from over a year ago obsolescent) and we need new figures for credibility.

People don’t necessarily become more demanding; maybe in the earlier days they said, “I don’t need this, it’s taking too long, I’ll just give up,” whereas now they are resigned to the Internet being slow.

Also of interest would be making a site massively faster (e.g. by an apposite service worker implementation), but A/B test on the rollout of it. Over several months, ideally.
Sorry, I don't understand. Could you give an example?
Digital Signal Processing is a fundamental field in electronics and always will be as long as we have any form of electronic communication or signals. Most modern active electronics parts (even many power converters!) fall under either analog or digital signal processing so it's a core field of study. Technically, your CPU is just a power hungy multipurpose DSP but we don't refer to them as such to maintain precision in the jargon.

Proper DSP chips are highly specialized processors just like GPUs except they contain lots of silicon for low latency and low power math. Your wifi or cellular radios, for example, are highly specialized DSP chips that only deal with a few protocols.

Your first article debates the efficacy of current attempts to investigate infertility:

Recent years have seen many similar reports of falling human sperm counts, but there has been much debate over whether the problem is real. “The principal trouble has been selection bias,” says Joëlle Le Moal, an environmental health epidemiologist at the Institut de Veille Sanitaire in Saint Maurice, France, and joint first author of the new article with colleague Matthieu Rolland. She explains that few studies have involved sperm samples collected from randomly selected members of the general population; for the few that did, only a small percentage of men agreed to be included, and the studies were run in restricted areas. So most studies have had to rely on sperm donors or couples coming to fertility clinics, which do not represent the general population.

That article focuses on France, which is rarely counted among developing worlds. The second article is paywalled. The third two could easily be considered Submarine Articles[0] for male supplements and stimulants.

I like to think of IQs using a car analogy.

You can have someone with an 8000 HP motor for a brain cranking away like a nitromethane dragster. These people don't have a ton of practical utility, but if you point them in the right direction and let 'em rip, they shred through certain problems like chainsaws through logs.

If you want to be successful, be a Porsche. Optimize for driving well on the most practical terrain that can take you the most places.
Poker Square
Our story focuses on resisting anathemas of Poker Gossip. Isn't doing something with strategy not accepted as smartness in the world of Poker? Its all in the mind. Its takes an expert to know the delicacies of Poker. As royal as it stands it is indeed a game of the smart and brainy.

With the aim of bringing a user friendly on line app to those set of poker enthusiastic users our team had started working on a gaming application called "Poker Square" here at Zigbee Apps. With creative ideas, engagement strategies and streamlined technologies we have structured this concept of poker into an online platform of interaction. This helps the Poker players to participate in championships and leagues Anytime, anywhere in the most famous Texas Hold'em like never before.

This is a complete misunderstanding of US nuclear policy and weapons systems. It's designed to enable the president to launch missiles at any target as rapidly as possible, not to doublecheck or safeguard against him.

You might say "sure, but there are people who have to actually execute those orders." But give the Pentagon some credit--those are people who have been systematically selected because they follow orders quickly and without question. For example, consider what happened to Harold Hering when it became obvious that he was not one of those people.
Okay, so you disagree with their world view on a number of points, but many in the other camp would say that they are taking a principled stand in those actions and attempt to claim the same moral high ground. As an example, take what you view as "openly deceiving" the public on climate change. Right or wrong, it can be (and is) argued not entirely disingeniously that there is a totalitarian undercurrent in the course proscribed to resolve the looming crisis. The debate often devolves into name-calling and pushes back from actual meaningful communication.
I feel like the phraseology and the casting of every single issue in the current political discourse into an absolute moral / ethical question is the poison that is killing our system. We now have mass media echo chambers of all sides and flavours that can reinforce and magnify the differences between any two not entirely dissimilar world views instead of focusing us on the commonalities between them and guiding us to communicate. Take climate change again, there is an entire spectrum of belief regarding what it is and how to solve it. There are people who advocate ignoring global warming as a hoax and some who want to reduce global populations and roll back industrial production, and thousands of different areas in between and elsewhere. In each of their worldviews, most of them genuinely hold their beliefs and when presented with an existential threat to those beliefs, rather than seeing it as two sides of a coin the habit is to resort to good vs evil etc. The solution IMHO is to work on improving the arguments of all sides and the art of debate in general. If a person advocates that there has been no warming at all, which contravenes quite a bit of research, holders of different views should focus on improving their presentation of fact through argument, rather than what I feel in most cases is the more typical practice of customarily calling each other kooks and crossing the street.
Fluctuation theorem

Maybe it's just because I only just woke up, but somehow I managed to read that sentence without even realising it wass awkwardly worded.
Let me just elaborate on the ‘complex motivations’ idea, because I certainly think that ‘orthogonality’ is the weak point in the AGI doomsday story.

Orthogonality is defined by Bostrom as the postulate that a super-intelligence can have nearly any arbitrary goals. Here is a short argument as to why ‘orthogonality’ may be false:

In so far as an AGI has a precisely defined goal, it is likely that the AGI cannot be super-intelligent. The reason is because there’s always a certain irreducible amount of fuzziness or ambiguity in the definition of some types of concepts (‘non-trivial’ concepts associated with values don’t have necessary definitions). Let us call these concepts, fuzzy concepts (or f-concepts).

Now imagine that you are trying to define the goals that will let you specify that you want an AGI to doprecisely, but it turns out that for certain goals there’s an unavoidable trade-off: trying to increase the precision of the definitions reduces the cognitive power of the AGI. It’s because non-trivial goals need the aforementioned ‘f-concepts’, and you can’t define these precisely without over simplifying them.

The only way to deal with f-concepts is by using a ‘concept cloud’ – instead of a single crisp definition, you would need to have a ‘cloud’ or ‘cluster’ of multiple slightly different definitions, and it’s the totality of all these that specifies the goals of the AGI.

So for example, such f-concepts (f) would need a whole set of slightly differing definitions (d):

F= (d1, d2, d3, d4, d5, d6…)

But now the AGI needs a way to integrate all the slightly conflicting definitions into a single coherent set. Let us designate the methods that do this as <integration-methods>.

But finding better <integration methods> is an instrumental goal (needed for whatever other goals the AGI must have). So unavoidably, extra goals must emerge to handle these f-concepts, in addition to whatever original goals the programmer was trying to specify. And if these ‘extra’ goals conflict too badly with the original ones, then the AGI will be cognitively handicapped.

This falsifies orthogonality: f-concepts can only be handled via the emergence of additional goals to perform the internal conflict-resolution procedures that integrate multiple differing definitions of goals in a ‘concept-cloud’.

In so far as an AGI has goals that can be precisely specified, orthogonality is trivially true, but such an AGI probably can’t become super-intelligent. It’s cognitively handicapped.

In so far as an AGI has fuzzy goals, it can become super-intelligent, but orthogonality is likely falsified, because ‘extra’ goals need to emerge to handle ‘conflict resolution’ and integration of multiple differing definitions in the concept cloud.

All of this just confirms that goal-drift of our future descendants is unavoidable. The irony is that this is the very reason why ‘orthogonality’ may be false.

> I really want more evidence of the importance of performance in web systems (to justify my hobby, if for no other reason), but things from ten years ago just don’t cut it.

> Can we please stop citing articles from ten years ago and cite some studies that aren’t more than two years old?

Could you explain why? New data is good, sure but why should we disregard old data? I think instead of asking for people to simply discard old data, you should point out the issues you believe the data has so that they can be addressed (with newer data if necessary).

Anyhow, from https://riteproject.files.wordpress.com/2014/10/fact-sheet.p...:

- "In 2008 the Aberdeen Group found that a 1-second delay in page load time costs 11% fewer page views, a 16% decrease in customer satisfaction, and a 7% decrease in searches that result in new customers."

- In 2009 Microsoft Bing found that introducing 500ms extra delay translated to 1.2% less advertising revenue.

I also found a whitepaper from 2010 done by Gomez.com that shows how speed impacts various metrics: https://github.com/JasonPaulGardner/po4ux/blob/master/InfoPa...

There's also an article from 2013 that's only loosely related but shows that reducing TTFB latency can increase search result rankings: https://moz.com/blog/how-website-speed-actually-impacts-sear...

> Also I’d be interested in more geographically diverse results.

I'd love these too, let me know if you find them.
Basically there is no sharp division, but the more the observation spreads, the harder it is to reverse. For one isolated particle, it's easiest. Anything we can reliably read is basically permanent, like a bit flip in a computer.

So once a photon is detected, like by making a mark on a screen or camera, it's permanent. In the delayed-choice experiment this happens twice, once for the "interference pattern" and again after the choice.

If you accept that, which I think is intuitive, then it makes the DCQE much easier to grasp. If you want to understand the experiment better, I would recommend this thread:

An alternative choice for Android KitKat users with non-rooted phones/netpads, is to use/try the "NoRoot Firewall" app by "Grey Shirts", imho its one of the best firewall, which uses kitkat-specific internal-VPN-routing module to process & filter network trafffic packets. VPN network traffic filtering process works locally inside the device, no external servers/cloud etc are used. It allows to create multiple (outbound) TCP protocol based rules for each app, based on outbound external/remote domain-names, domains with wildcard subdomains, IP-address, some IP-Net ranges, specific single port, etc. Can show reverse domain names of outbound traffic IP-address, etc. It does not use any excessive or Privacy violating or intrusive Permissions. And, it does not support IPv6 net-pkt filtering, cannot handle ICMP, UDP, MultiCast, etc packets, cannot set inbound specific rules, cannot handle multi ports in same rule, etc. It does crash sometime too often, if there are too many outbound traffic. All mentioned features (and limitations) included & available for use, for free :)
> Or try out Thinkpads or XPSses with some flavour of Linux but I don't have high hopes for their touchpads and screens / HiDPI software support.

Touchpads generally work perfectly out of the box, with any Linux distribution that uses libinput instead of one of the older drivers. HiDPI screens also tend to work perfectly out of the box, though you may wish to tweak them to your tastes. (For instance, I don't want to treat a 1440p screen as 2x 720p, I want to treat it as 1440p with only slightly enlarged fonts.)
You miss a key point in what Hilary was saying

>And to all of the little __girls__ who are watching this, never doubt that you are valuable and powerful and deserving of every chance and opportunity in the world to pursue and achieve your own dreams."

No woman has ever got the position she was after. It may be a little disheartening as a female to see the only woman who has ever come close lose the way Hilary lost. Males have no trouble finding a role model for the position. You're finding a problem where none exists - males don't need role models for that job but females do.
Amazon 3P seller/manufacturer here: this is what they mean and do when they say your margin is their opportunity.

It means people can't just go to China, lock down a manufacturer, and sit easy for years flipping the same old product without actively trying to push the product forward. Amazon will play the same game with you, and they have the advantage of sales data + a willingness to drive traffic over profits.

In a similar spirit, they also do this to distributors who basically order case packs from manufacturers then list them on Amazon -- once you reach a certain volume Amazon contacts the manufacturers themselves and cut you out.

I wouldn't be surprised if Amazon starts building their own factories after awhile to replace out manufacturers -- vertical integration is their playbook.
