How prevalent is computer simulation in macro-economic research and forecasting?
The question revolves around another motivating question: How does economics become more effective at predicting the behavior of the macro economy? For example, how does economics develop methods that allow it to predict with some certainty, more certainty than current methods provide, that a recession in country A will occur?

How much is simulation used by economists and institutions? I know that the Federal Reserve in the US conducts bank 'stress tests', which are a sort of simulation. I'm wondering if this approach has been expanded and scaled to answer other sorts of economic questions.

Are there any institutions or researchers developing simulations as a core part of their research?
Hi jv22222, we don't get ramen off of this project. We plan to add paying functionalities some day if they make sense.

Set up milestones. If he hits those milestones, he gets pre-agreed upon tranches of equity. If he doesn't hit those milestones, he doesn't.
It's also cheaper and uses a lot less power, which is pretty surprising.
"Geeky" is the wrong word to use here. Educated people with ""good"" jobs have children later - geeks that work in software/STEM/medicine are included.

Plenty of my non-geek friends with good income careers are just now trying to settle down at 30.
I do not dispute the claim about the existence of a quantum computer which surpasses its classical brethren. Scott is correct.

I do disagree that it is exponentially more difficult to add a qubit. Coherence times are something to optimize, and densely packing qubits is also difficult with coherence times, but the notion of adding a qubit to a system doesn't come with an inherent exponential difficulty.

Regarding whether it is useful or not to learn quantum computing for your profession, if it's true that systems can be built that grow with exponential power, then they'll be relevant faster than one might think.
It just shifts your traffic egress location to a cloud provider, but this is valuable because all of the last mile Internet providers in the US colluded with the government to get permission to use your internet traffic to sell ads, so if you care about privacy, and not allowing your ISP to inspect your traffic, it's a huge benefit.

AWS will make no secondary use of customer data. The ISPs have told us they will, and the FCC gave them permission to do so. Which one will you trust? I know I would trust AWS any day over the ISPs...
ProtonMail announces VPN service
I've been considering just buying a few prepaid SIM cards just for services like this. I'd love some throwaway phone number/ SMS-forwarding services, but most get blacklisted within a few months because spammers immediately jump all over them.
I use vim (or vi on some antiquated machines). Others in the company use Emacs, Visual Studio, Qt Creator, Sublime, and so on. When the company was more startup-ish, it was a matter of individual taste, influenced by their IDE/editor. Giant checkins of mostly whitespace changes eventually became an issue, and were banned. Years later, and the code it mostly spaces, but I see places in the code with random tabs in between, every now and then.

For my case, vim handles a bunch of auto-format and auto-indent options turned on, and replaces the tab key with 4 spaces, unless I'm editing a Makefile (where commands to execute are preceded by a tab character).
Algo isn't that much better than any other VPN - arguably it's slightly better security wise, though I'd argue Wireguard tops it by far on cipher choices and security margins.

Ultimately VPNs just aren't for hiding anything that could cause you significant problems. If you want that, Tor, i2p, or piles of hacked boxes are your only options really if you must interact with the clearnet.
60+ million urban Americans don’t have access to or can’t afford broadband
If a washing machine waits up to say 30 minutes unless you click the fast button, that's still quite a bit of time shifting in aggregate. Same for home heating/cooling, you might be willing to shift an extra 1-2 degrees if it will save a few dollars a month and you don't need to pay attention. However, if your willing to spend a few extra dollars a month that directly pays for grid storage.
The two language problem is more specific to scientific computing where literally every popular library is written in more then one language - fast C/C++/Fortran and convenient high-level R/Matlab/Python. NumPy, SciPy, Caffe, Theano, Tensorflow to name a few. I once had to rewrite Matlab + C code (for face tracking) to pure Julia - not only the resulting code was almost twice smaller, it also ran ~20% faster.
I'm not sure if with foamglass they mean an aerogel made of glass. That stuff has wild thermal properties.

How to start being a web developer
Unlike adding RAM, adding each extra qubit is also exponentially harder, since maintaining coherence of all the qubits becomes more and more difficult. That's why scaling from the tiny quantum computers we have today (which are not useful) to a useful quantum computer remains a decades long research agenda.
I know right? I noticed this too and it really put me off the platform.
The per-socket performance might be a nice "marketing hack", since a lot of big-iron software is sold and licensed as "per-socket".

IIRC, Windows Server is sold per-core however. So lots of cores may rise the total-cost of ownership in the case of Windows Server.
Many pieces of Daala are being folded into AV1, which is an industry effort supported by most large software and hardware companies to produce an HEVC replacement. This post summarizes the results of the different experiments: https://people.xiph.org/~jm/daala/revisiting/

Unfortunately some of the most innovative techniques around frequency-domain prediction ended up not panning out. :(
Except that "regular" is left foot leading and "goofy" is right foot leading.

In my experience learning to ride "switch" is only a matter of practice, and not much at that.

Anyone who juggles, or plays keepy-up (aka foot juggling) knows the importance of practicing evenly on both sides

Tying CEO Compensation to Stock Price Isn't Always Smart for Business
It's logical from a financial perspective for many people. When I think of older first time parents I think 30+. In the past upper 20s might be considered older because people would get married in young 20s and have children shortly after.

You want to be able to afford the increasingly higher costs of having children. You want your marriage to not be stressed from added financial responsibility. People tend to make more as they get older so many wait. That played a role in my decision to wait for sure.

The physical component you suggested is certainly a logical argument for having them younger. That pressure is higher for women too because they consider the risks of pregnancy (as you noted) and the possibility they may not be able to conceive if they wait too long.

I understand your decision but to me - having a kid at 30 over the physical concern is not logical. Sure I'd be 48 when they're 18 but even at that point, I don't have physical concerns. In fact, that would provide additional motivation to remain healthy. If I was considering physical capability for grandkids then that might enter my decision. My wife just talks about how we'd be the older parents in our kid's class which doesn't concern me.

Everyone's situation is different though. I just think finances is a big driver for those that wait and honestly I think it's a good one. If you're married and don't have your finances in order, there's a good chance your marriage won't last and you'll rack up more stress which isn't good for you or your kids.
Not everyone in on Windows 10.
Thanks, my link only works for me...
I would agree, but there appears to be a 15% to 20% improvement of efficiency. Meaning, the processing power per watt is worth more.
Perhaps. My dad was 36 when he had me and was deep into ham radio, and computers. I was influenced by all of that.
While the idea of donating to a library is always good, I doubt the usefulness of giving a library books on completely outdated technology that 0.0001% of people still use. Have you ever been to a used book store or library? Their tech section is nearly useless. I would honestly not want more tech books from 2002 unless they're well respected and in some way still useful.

I'd find a way to recycle them. The sad part about tech books is that most of them become useless after five years, if not before.
Bandwidth isn't really imgur's problem now.

So long as you have users, you have bandwidth, you have revenue.

The problem is now storage. As users and revenue may decline the bandwidth bill declines too... but the storage bill always increases and never declines.

This is the real problem with image hosting, keeping alive old images and storage costs always growing regardless of current usage and revenue.
I know this is exactly on topic but I thought it was an interesting angle to look data for simulations from.

AMD Unveils EPYC Server Processor Models and Pricing Guidelines
Not sure if the apparent stop start observation, and also one strand sometimes getting synthesized while the other isn't would actually occur in-vivo. This is a pretty cool technology but a heavily artificial in-vitro system at the end of the day.
On the subject of direction word trivia, the Sanskrit word for right, a cognate of Latin "dexter", is "dakshina." In this case, however, it eventually came to mean "south".

Why? It makes sense when you realize that the the word for ahead/in-front "purva" came to mean east, the word for back/behind "paschima" came to mean west, and the common word for north "uttara" can mean left. So the words imply an eastward-facing world orientation, which itself probably has its origin in worship of the rising sun.

It's literally true for what we are doing right now in this moment: emitting information through a keyboard.

But even then, it feels like we are doing much better than that. Maybe because we use implicit cross-referencing all the time.

Of course the Internet should be archived.

A large portion of the Internet will be archived regardless. Not archiving all of it just allows a more distorted picture of what happened.

Any piece of information that's produced is not simply "content" having "merit" but evidence for the structure of this society as a whole. The most ridiculous content still sheds light on other content and gives an explanation for the origin of still other content and even events.

And, of course, even if information has a set merit, it won't necessarily survive or die on that merit but rather on a combination of merit, who it money for, purely random factors and so-forth.
Ask HN: As a lazy but concerned user, how do you run your own email server?
What the easiest to have secure email server (open source & auto-updated, not necessarily free) running on a VPS. I've been looking into:

* https://yunohost.org/ (has email server, open source and free, GNU AGPL v.3)

* sandstorm.io which hinted at email server, but seems to be stalling

* http://cloudron.com/ which seems interesting but couldn't find much reviews

Yunohost covers the bill, but I'm surprised it has no tracktion on HN, no comments/reviews.

Are there alternatives I'm missing? What are your recommendations?

Background: Given how important email has become as authorization and how sometimes account access is hacked or revoked + how the email data usually stays with the provider I'd like to run my own server.
This is for an SRE role who would need to work during on call, or for whatever reason decide to WFH.

Bay Area (Between SF and SJC):

- Mass transit is awful. This doesn't have to be the way but because of nimbyism and politics it is. Electrify caltrain? Extend BART? Improve service levels? Queue years of arguments...

- If a public good can be privatized, a VC has already jumped on that idea... creating what feels like a technocratic society.

- Lack of diversity. Go out in NYC and you'll rub shoulders with people from all walks of life. Go out in SF and you'll be around mostly techies because non-techies can't afford to live here.

- Housing prices are insane and new construction is consistently blocked due to nimbyism.
There used to be a long running joke (I think perhaps Linus even coined it?) that the kernel codebase grew about as fast as CPU performance improved. I guess that died around the time AMD released their dual core CPUs..
That was expected, since Apple are part of MPEGLA cartel and they strongly oppose free codecs. But it doesn't really mean anything, since everyone else would have to pay arm and leg to use it, so the pressure to adopt free codec is still here. I hope AV1 will come out soon enough. Daala itself isn't really ready as is.

> Which, of course, leaves a trail of forum posts, comments, etc, with broken images and links.

I remember this from long long ago, when I was a student and helped running a vBulletin on the side for fun. When I noticed this trend while browsing older posts that had the a lot of imageshack embeds (they apparently deleted old files which weren't accessed that often, also the url format might have changed once) I cobbled together a plugin that would save all posted images locally and then serve those instead. This lead to some protest however by people who had those fancy dynamic images in their signature that would show the currently playing song or similar, so those had to be excluded...
It annoys me when IT folks despise recruiters and refuse to acknowledge how lucky they are for being stalked by recruiters.

It was kind of flattering until I realized most of them never works for me.

They'll call, ask a lot, ask me to submit a cv although my updated profile is already on LinkedIn. They'll ask about salary expectations and then I won't hear from them again.

(BTW: Yes, I walk from one nice job to the next, can't complain. But I've found that for me talking to recruiters is pointless most of the times. FTR: I got my current job through a recruiter, first time in ten years I actually got a job through a recruiter.)
The security of Wireguard is completely unknown. Sure, it might be more secure after a formal release and a security evaluation.

They even state themselves that they should not be used if security is required.

Machiavelli misunderstood
At low bit-rate, lame applies a low-pass and resamples to a lower sampling rate. If it didn't to that, MP3 would end up completely starved of bits (trying to code all frequencies) and have really atrocious artefacts. Based on personal experience and the results from a few listening tests I saw, I think you can assume that Opus can now give you about the same quality as MP3 for about 60% of the bits. For example, 76 kb/s Opus should be around the same quality as 128 kb/s MP3.

I might be wrong, but this looks very much like penny lick ice cream glasses: https://i2.wp.com/www.oldlondon.net/wp-content/uploads/2016/...

(If you haven't heard of them: in the 1800s London, one happy customer would get their ice cream, lick the glass clean and return it to the vendor, who would refill it and give it to the next customer. Perhaps the best way to spread tuberculosis, which the Penny lick did very well on until it was banned in 1899.)
Cray CTO on the Cambrian Compute Explosion
Welcome to the science of fire. If you pump energy into a system faster than you are removing it then you are heating it up, if you pump energy out faster than you are adding it then you are cooling something down.

This is how hay bales that are a little moist will catch fire, the digestive process (which is slow but exothermal) of the bacteria in the center of the slightly rotting bale of hay are so well insulated from the outside world by the rest of the hay that the temperature will at some point exceed the ignition temperature of the hay and then you have spontaneous combustion.

Something very similar can happy to driers if the exit ducts become more clogged than a certain percentage.

And let's not even talk about gas fired dryers (does anybody still use those other than dry cleaning services?).
This needs to be an out-of-sample test.
No harm taken, the service is not perfect yet and it lacks a lot of functionalities, that we can agree on.

It works on android phones with chrome, but like you said I wouldn't remember the generated addresses, so we think the extension is a big part of the service, and unfortunately, extensions are not available on mobile. We're working on the subject to find the best solution possible.
We learned about hereditary traits long before gene sequencing even existed. You do not need to know how something works on a genetic level to make strong conclusions about heritability.

That being said, this specific case looks like bad reporting about a tepid study, so I wouldn't be surprised if it were totally wrong.

Sadly, Google is trying to patent AV1, and only giving a patent license to users of its implementation.

If you want to build your own implementation, either to implement it in hardware, or to release it under a different license, then you’ll be fucked.
60x is just ludicrously wrong.

I said that FP16 performance is at least 60x worse, which it absolutely is. The cores on the GT102 do not natively support FP16, so each FP16 operand has to be converted to FP32 and then processed, with significant overhead. The P100 can use FP16 directly yielding not only double the processing speed (because the FP32 cores are really dual FP16 cores, like registers on an x86), but a major memory savings. The 1080(Ti) is crippled at FP64 as well, again dramatically slower than the P100. It's a consumer GPU and FP16 and FP64 just aren't usually a consumer need.

These aren't just the same thing, with one having a sucker price. They are dramatically different chips, and many applications require the P100.

just like P100 and 1080 before.

Comparing the P100 and 1080Ti as if the latter is the consumer version of the former is not useful. They are profoundly different chips.

I run my own email server and have done for ~25 years, but what do you mean by 'secure'?

SMTP isn't a secure transport.

Having your email stored on someone else's computers (ie the cloud) is not necessarily 'secure'.

Having a well-constructed and well-managed host somewhere you physically control seems to me the most 'secure' arrangement, which is what I have always had. Currently for the cost of a Raspberry Pi and occasional 'apt-get update' etc.
If you look up Sorkin's earlier articles, he'd also posted recently on some failed / dismantled conglomerates -- the use here quite probably refers to that, which his regular readers might get.

There's a lot of invective in this HN thread that is directly addressed (Berkshire-Hathaway, etc.) within the article itself. This suggests things.

I'm well aware that ngrams aren't absolute proof and that language itself changes (quite particularly in business and finance). But it is a datapoint to be considered. Answering it from ignorance isn't a particularly strong counter.

Hi dmitrygr, the idea is not new, but the link you gave is for disposable email addresses, which are public. That's a different use-case from nBox, where the addresses are private.

IOT security is a nightmare, I don't expect self driving cars to be much better in this respect, they're essentially a griefers wet dream.
As mentioned, we have had collaborative editing with full history for Jupyter notebooks since 2014 in https://cocalc.com, which is open source by the way. We've written and rewritten this functionality 3 times now, culminating most recently with a complete front and backend rewrite of Jupyter from scratch for CoCalc. See http://blog.sagemath.com/jupyter/2017/05/05/jupyter-rewrite-... for more details. We also still support collaborative editing using Classical Jupyter.

This change probably won't make me any more or less likely to use Uber. The main thing that keeps me away from Uber is their terrible UX.

Getting a ride is way too streamlined - every single time I have used the Uber app (infrequently), I was not sure if I had committed to requesting a ride yet. This is the most annoying thing. Also there is no obvious means of scheduling a pickup time.

Lyft UX is a lot better and the company seems to not be run by assholes, so I like to support that whenever I can.
I thought the whole problem with patent trolls was that holding a patent with no intent of commercializing it was perfectly legal.
But you said "When one unit of resource doubles your computational capacity" which I believe is what your parent comment rightly called bullshit.
For now they still have trouble staying in their lane, I don't see any lack of reasons to pull them over, in fact I'd love to see them taken off the roads entirely until such bugs have been ironed out. Public roads are not the place to beta test software.
