Where would you introduce the trajectory-correcting algorithm?

In General Relativity, fundamental particles are simply taking shortest paths through spacetime, and where there are multiple short paths, the one that extremizes the timelike distance is favoured.

In a perturbative theory of gravitation, you introduce corrections on the particles by way of graviton interactions.

Worse, whether a local patch of energy-density amounts to a particle is observer-dependent; in both approaches above an accelerated observer sees more particles than an unaccelerated one does. That includes more gravitons in the latter approach.

It would be a lot of work to write down a theory in which particles (whose count isn't global) decide on corrections to their own trajectories that return themselves to a path similar to one along a smooth manifold even though they are "really" travelling along a non-smooth one, so long as you are trying to match well-tested results of General Relativity. (A theory which doesn't reproduce those results is maybe an interesting toy; "cheating" by using a nearly-but-not-quite minimal length that has no direct observables is an uninteresting toy, and is not really a good argument for the existence of Simulators (or Creator Gods or whatever).)

In particular, the non-linear contributions of gravity will likely lead you into an explosion in the amount of knowledge that a particle would have to acquire in order to assess its trajectory; you'd probably also want to propose an explanation of how it goes about adjusting its trajectory when it discovers it's not on the "right" one. Don't forget to make this correct for all possible observers, including the ones that will see no particle and those that will see two or more particles.

In practice, attempts to do away with infinitesimals of length that do not clearly fail to reproduce known physics also tend to produce infinities of state in matter and/or additional gauge fields, and the infinities don't succumb to information-reduction techniques like renormalization by power-set counting.

If you're looking to encode that knowledge somewhere, like in a spacetime-permeating field, the gravitational field of General Relativity is right there and already serving that purpose in a non-toy theory that (in explorable parts of the known universe) behaves completely correctly with quantum field theories of matter, including The Standard Model. :-)

Best of all, in a block universe model, the whole thing is "pre-rendered", and there is no difference between the block universe model and an initial-values-surface formalism in the presence of determinism. So you only have to fully render one frame, and you get all the others, past and future. (Quantum mechanics as we know it is deterministic -- that's unitarity.)

Ask HN: I bought a server for research. How should i configure it?
64 GB RAM, 1 TB SSD, 8 TB HDD, Nvidia 1080 is my configuration. What OS should I install? How should I partition my hard disks?

By research, I mean trying out GPU based databases, deep learning etc.
Have you heard of anyone running BrainFuck in production?
What about "earnest, blunt, non-sugar-coated feedback" that is useless, uninformed, and counterproductive to researchers? I was under the impression that that was the concern here.

Just because someone says something non-sugar-coated doesn't mean it has any truth or value to it. In my experience, a lot of the people who publicly congratulate themselves on never pulling any punches and telling it like it is and keeping it real, etc., aren't motivated because they feel like they have valuable feedback to offer (they usually don't), but rather it's just a way to act out and maintain a tough-guy public persona that they want everyone to believe in.

I'm 100% in favor of public peer review, I just question the value of stereotypical Linus Torvalds-style "I'm just telling it like it is, you idiot" feedback that some people fetishize in these parts. The best course of action here is by definition whatever leads to more and better research, with whatever the appropriate amount of public and private peer review is that leads to that outcome.
I would be nice if they would continue to maintain the big endian PowerPC branch of Go, as that appears to have atrophied in recent years.

From a software quality standpoint, testing on older Apple PowerPC gear is probably the cheapest (PowerMac and Xserve G5's are in the $100-300 range on the used market) and highest performance big endian systems available, and they're still natively supported by a lot of mainline distros, Ubuntu in particular.

The only other BE systems out there of comparable performance are SPARC systems which either are very expensive or have low-single threaded performance (T1 and T2 based).
It might not be exactly what you had in mind as 'in production', but it's probably worth noting that Unity uses Mono as a core component, and it seems to be fairly popular on non-Windows platforms.

Another Wally post that gets many comments. Perhaps I am the only HN poster with actual working experience at wally - in the retail area too. So let me react to others' posts.

The Walmart worker image I seem to read by comments are the sales floor and cashier type associate. Yes, there are Some that you wonder if they can be employed elsewhere. But that is not even close to a majority at the store I know about.

Can a Walmart worker work at a Starbucks? Of course!! Can a Starbucks worker work at Wal-Mart? Sure. But retail sucks at times and I would bet more Starbucks -> Wally failures than the other way around.

Many wally workers have been there decades. They earn 50 -125% more than the $10/hr publicised. First level managers Get the 48k required to avoid overtime when the new law takes effect.

Since the new wage hike in my store there has not been any "ventilation" of out with the old and in with better employees. Its really really hard to hire anybody now. Heartbeat? You are hired.

Promotions come at such a rapid pace it is truly wonderful to see. 20 year old given 4 Promotions in 18 months to become assist the manager at 48k. It happens. On another site Many posts about how rapidly promotions occur. Many store managers who make 130-250+ and more started out selling dirt alongside those "can't be employeed elsewhere" associates. In many cases it only takes 10 years to get to that level.

Retail is its own form of servitude. It's hard. Takes work and a special person to succeed. Once off the clock you can not work.

The "$10" pay more to employees was a brilliant move. The press ate it.

I'll finish by my own transformation. I used to think Wally workers were in a class of their own. I worked at Costco too. There is no difference. There are substantially fewer Costcos than Wally. And Costco has much less need for employees. So you don't see the "can't work anywhere else" types.
Not trying to shout "think of the children" but for the sake of discussion would it still seem strange if the crime was hypothetically murder?

To me it seems clearer cut in a case which is more obviously criminal.

Now unbalanced extradition, which is the case for us in UK with regard to the US, seems odder to me. Our politicians should sort that out.
Yeah may be but who knows what the future holds!!
>In my experience this problem could be alleviated if it were possible for a worker to work a 50-60 hour week at a single job without incurring additional expenses for their employer.

How would working more without any more wages actually help the worker? Or do you mean the worker would receive their normal hourly wage without the "additional expense" of time-and-a-half overtime rates?

This scheme sounds insane, a recipe for slave-driving and exploitation of the worst kinds.

Kroger and Publix both seem to offer ~50,000 items in their larger stores.

They don't have a full department store and will thus likely have a greater variety of groceries than the Walmart, but they don't have greater variety overall. I would argue that they are a 3rd variety of big box (along with mega stores and club stores), not the same as Walmart.
I agree that it has wide room for improvements, but I still find it very comparable to Eagle, for example.

But it is in a steady improvement route, while operating in a much harder segment to attract the resources they need than most free/open-source projects: their best users aren't high-level programmers, neither UX experts, and UX experts and high-level programmers aren't their typical users[1].

I still use Altium for my most complex designs, even for reasons beyong those you've posted, but it surely can be used for professional projects beyond the simplest ones, even taking advantage of the automation by learning a few simple patterns.

[1] Except, of course, by coincidence. As a primarily hardware engineer, I'm trying to help by re-learning desktop programming, something I haven't done in years.
I'm not sure what you mean by non-popular. Much that is popular on HN is unknown to most people. My take:

* Multiping: Simple utility that pings multiple hosts, and displays the results on a zoomable side-scrolling graphs that sync by time. Thus you can immediatley see, for example: At 08:06:33, of the hosts on my route to the Internet, the local firewall responds, as does my ISP's gateway, but the next hop and everything past it are timing out; and the same thing happened 4 times in the last week for periods of 2, 18, 6, and 11 minutes, always around 8am.

Just look at a screenshot (I'm talking about the three horizontal graphs in the middle, you can have a many as you want of those):

http://www.multiping.com/images/multiping_screenshot_big1.pn...

* OpenBSD: I just installed it for the first time. Despite it's reputation as an ubergeek tool, it's shockingly, exceptionally, elegantly easy to install (for technical folks who know what DHCP and MBR are). The documentation is amazing, so far, and if the rest of the experience is like the install, I'll be very happy. A pleasure to drive.
I don't think any creator of any "secure" messaging product would claim something like this.

But, given the possibility of something like this happening either way, this is why clean open protocols are more important for decentralized software, than reference clients.

> It just means that you now have to spend more effort keeping all your petty graft secret at the low end

The problem is that secrecy doesn't purely serve 'petty graft', but also allows politicians to actually make deals and get things done.

The thesis that 'raising the cost of secrecy' is always a good thing is unproven. Plus, Assange et al are less a neutral information source, but rather an active participant in politics with their own, hidden motivations.

Over the last 30 years, we've repeatedly seen the reform of politics in the US aimed at eliminating graft and taking power away from politicians and putting it in the hands of voters. Over the same period of time, politics here as gotten more and more dysfunctional.

Relevant:
http://www.theatlantic.com/magazine/archive/2016/07/how-amer...

I submit that voters are often unable to effectively make compromises and form voting blocs with others. It used to fall to politicians to negotiate behind closed doors to hash out a deal. In Assange's secret-less world, that won't be possible.
Bioinformatician here. All my formal training is in biology, but I've spent most of my research hours learning CS, statistics, etc, rather than biology.

> An astonishing amount of biology is rather mechanistic, systematic, and logical.

I disagree vehemently. Or, to be more precise, it is very likely that this is true in reality, but in terms of the dominant way it's viewed in both clinical and research practice, it's very much not.

The average paper's findings are qualitative, not quantitative, in nature. Of course, numbers, statistics, etc, will be used -- but they will be used to get p-values to support a qualitative conclusion, rather than to work towards a quantitative, systematic understanding of biology.

There are exceptions, of course -- a decent amount of biochemistry is quantitative enough -- but when you get to topics like cell signalling, "cell biology", etc, it is almost never quantitative.

I have a favorite question I like to use in seminars when someone is presenting findings along the lines of "protein A regulates protein B". The question is: "Among the various regulators of B, how important is A? Is A a key regulator of B, or simply one of many?". Or, even more simply, "What is the most important regulator of B?" I invariably get blank looks, as if this is an unreasonable or impossible question to answer. Of course it is, as long as your models are qualitative. The point of the question is to get the speaker to think about that, but so far, no luck.
Could I burden you for a link to that, if possible?
Why not? programs as Training sets can do it I guess. Atleast for the mundane tasks in software like a large chunk of devops and UI stuff.
I'm impressed that they were able to find 24 references to cite.

I basically agree with everything you said, and I don't think we contradict each other. If I were to start an electronics company today, I would almost certainly choose KiCad and use it until I had some serious revenue.

But if demanding electronics are your bread and butter and you have several million Euro revenue per year, saving a couple thousand Euro in license fees by not having a professional EDA tool is hard to justify. KiCad just isn't there yet, though it might be in a few years.

I won't claim it hasn't improved. I will claim there are a lot of rediscoveries.

Still, your point is fair. The section on secondary key retrieval is very high level. Bloom filters get just two paragraphs.

I think the biggest change in cs is the view towards memory. In much of TAOCP, care is given to the memory footprint. Much of day to day programming is completely ignorant of memory. Scarily so.
The extension can be used apart from Redux, with any architecture which handles the state. Just connect to it and send actions and states. There's an implementation for MobX [1], for Angular ngrx [2], for RethinkDB Horizon [3].

Some (maybe) lesser known gems for Windows machines:

You and I have similar interests. I write documentation and perform other community evangelism tasks.
Up until the mid-2000s, if you wanted an easy up-and running web application environment without paying Microsoft, PHP plus MySQL was the only game in town. There were alternatives, but they invariably involved maintaining your own server and doing quite a bit of legwork yourself. The was no Heroku, no AWS, and tooling for python, ruby, and other environments required much more expertise to simply get an app responding on port 80.

Almost any big app you can point to that is built in PHP today was bootstrapped in this environment.

I did a lot of PHP from the late '90s up until 2008. Maybe things have changed in the intervening eight years, but I cant say I miss it.
You also work in a place where it is not acceptable to be performing a task for the first time, as they are of importance enough to require prior experience, and hence usually do not evolve quickly. Software is constantly changing and software developers are much more likely to completely overhaul a product than a physical design. They will also deal with changing dependencies due to updates and, in things like Javascript land, what way the wind happened to blow that day. Software developers are constantly on adapting and uneven ground for most products which strive to keep very up to date.

At places where true software engineering work is required, like mission critical systems, the type of planning that you may be used to will be more common. However even for large companies like Oracle, things like the healthcare site can go wrong [1]. That is just the nature of having to constantly adapt. If things just stayed stagnant, we could get the same level of safety and generations of consistent improvement that things like cars have received, which does happen with maybe Unix or C perhaps. But that does not change the fact that most day-to-day software development is all about hiring someone who knows slightly better than you, but, more importantly, knows how to learn how to get many reasonably new things done which involve parts of what he knows. We don't have the luxury of using safety or danger as a warning, usually.

I don't fully understand how paying worker's more money makes the stores cleaner, have brighter lighting, or ensures that the shelves are stocked. Much of that has to do with spending money to remodel stores, paying more money to ensure that enough staff are employed to clean the stores (McDonald's is famous for cleanliness thanks to the leadership of its founder), and improving logistics and ensuring there is enough staff to put items on shelves. I'm glad people are getting more money, but I see a correlation with higher wages not a causation, and I don't see they changes in budgets for the stores which may account for the higher sales per store.

According to Megan McArdle's article on Walmart and Costco [1], Walmart has one employee for every $211,000 in revenue while Costco has one employee for every $620,000 in revenue. For each dollar of revenue, Walmart hires 3 people compared to 1 for Costco, which has 107,000 employees.

Thus, if Costco were using Walmart's metrics, they would hire about 215,000 additional employees, most of whom would need only a high school education, at that. Jobs that can be done with little education are the jobs that are being exported to Mexico and China.

Interestingly, articles on paying higher wages never seem to focus on the number of people employed.

Indeed!

However, history suggests that translating that laudable sentiment into actual resource-allocating policy and social organization is upon occasion slightly less than maximally clear, obvious, or straightforward.
The article mentions:

That one of the people with criminal charges is an employee of the library who tried to get the guard to stop assaulting a member of the public:

> Both the librarian and the patron face criminal charges.

That the guard had ignored their instructions about not interfering with people who pose no risk of harm to the other guests:

> According to the library, as part of the agreement nobody was to be prevented from asking a controversial question and the security team would consult with library officials before ejecting any nonviolent patrons.

That the question asker had offered to leave if asked?

> Rothe-Kushel can be heard saying, “Ask me to leave [and] I will leave.”

and so on.

I mean, this ...

> When he bounced out of the chair onto the floor, the guards forced him back into the chair, and handcuffed him.

... is a criminal offence in England.
Local and state governments and their elected representatives in the United States are soon going to get an earful from constituents about stunts like this.

Another thought: The FAA will soon be involved regulating drone advertising. I guess they already have some oversight over skywriters and blimps and airplanes dragging banners, but this takes things to a new level.
Wikipedia:

> The circular economy is a generic term for an industrial economy that promotes greater resource productivity aiming to reduce waste and avoid pollution by design or intention, and in which material flows are of two types: biological nutrients , designed to reenter the biosphere safely, and technical nutrients, which are designed to circulate at high quality in the production system without entering the biosphere as well as being restorative and regenerative by design. This is contrast to a Linear Economy which is a 'take, make, dispose' model of production

It is a mess and I pity the fools who have to implement it.
Another way is how WinCo does it, each employee can become an owner as it is majority employee owned, and it is a very well run place. Yes you can buy stock in Wal-mart or Costco and Costco has profit sharing, but there is something about owning a part of the company you work at that helps productivity, responsibility and caring what happens to the company. Personally I like shopping there because I know people there value it and more money is going to the workers.

One example of how this may be better is a lower performing store that is still making a profit may stay open, other larger chains may remove stores and cut lower performing stores even though profit is made. Not a flawless system but owning shares, ownership and being a part of the company in this way makes the best work come out of skilled people.

Yes price reductions lead to new demand, hence new jobs.

But what if for almost every human supplied product/service there's a good enough machine substitue, or even just a human substitue that demands very little labor ? couldn't we reach a stable state of high unemployment ?
New Zealand & Australia having a higher percentage of people working 50+ hour weeks over the US seems unintuitive.

Update - Getting downvoted, so here's explanation:

This doesn't align with the culture over there at all. I think this source is questionable.

For example, if you compare the average hours worked per worker over a year (descending), the U.S. is #18 with 1,789 hours while Australia is much lower at #27 with 1,664 hours [1].

Sure. But I was specifically speaking about these higher-paying jobs at Wal-Mart. The fewer jobs at Wal-Mart are more then offset by increased jobs elsewhere.
