Encryption --- along with unenlightening file naming, etc. --- seems like it would make this pretty trivial to bypass. Share the encrypted file and share the keys somewhere else.
There's nothing handwavy about the liquidity argument. Improving liquidity reduces the cost of trading for almost everyone in the market and thus makes almost everyone just a little wealthier. That means ordinary people, like schoolteachers and custodians, retire with a bit more money, and are a bit more comfortable; it means lots of people can donate just a bit more money to charitable causes without crossing whatever financial safety line they have, &c.

It's hard to make the same kind of argument about adtech.
Can you elaborate on number 1? For instance Numbeo summarizes:

Cost of living in Barcelona is 35.00% lower than in ____

You would figure it is really only 25% cheaper? Are you comparing just some itemized costs you incur on a business trip or are you actually moving to these places as a resident and making that observation? I ask because a 10% margin of error hasn't been my experience.

none, their goal is to optimize profits. They haven't gotten to a point where investing in cutting edge tech only research is seen by them as a value add. Also for such projects they stay away from open source collaboration with outside world - so that would be really slow to develop something useful. Hope that will change in future.(very few exceptions - as someone commented pandas - pandas creator at two sigma actually is pushing for open-source, i think it is great but i hope it is not just a gimmick to attract better talent).
>"My startup had to deal with payment processing (at least initially before I pivoted) so I thought I needed it."

You generally don't need a payment processor when starting out. The first ~200k in revenue can be done manually. Payment processing is something that takes time to do and most likely you will need to tweak it a few time as you figure out your business model.

>Paying for dev/design work by hour for a new startup is an insane concept to me now. There are always gonna be bugs, something that doesn’t work, something that needs to be added, etc.

Tech products are very complex. There are thousands of bugs and edge cases that needs to be resolved for a high quality product.

>And ideally, especially if you’re a non-tech founder like me, PARTNER.

One of the worst idea is to have non-technical people try to create a tech business without a strong technical co-founder. Imagine starting a dentistry office without any prior knowledge or a partner who is a dentist. Imagine trying to start a restaurant without a chef, etc. Creating a tech business is not a get rich plan. It takes a lot of skill, knowledge, and luck to get a business off the ground. Unfortunately, the media stories that we read make creating a great product or fundraising millions of dollars super easy. The reality is that running a start-up is probably one of the hardest things that one can do.

The biggest obstacle you'll face is that depending on how you present yourself a savvy manager will assume that you'll get a "better" job as soon as you can and leave them high and dry.

Besides that the best advice i think is that getting a "blue collar" job is no different then getting most others. It's about who you know and how much shit you're willing to eat. I've done ever from hanging drywall to writing R code. If you're personable and willing to roll up your sleeeves you can usually get something.

I don't get this sentiment. Boomers weren't all born in the same year, right now the "bubble" of US population is 50-60. because they do start dying off after that. But the trick is medical advances are likely to push the 40-50 year olds now (respectively, 50-60s make up 7% of the population while 40-50s make up 6%) to live longer and die slower, meaning they will probably still fit in the currently emerging retirement markets meant for older boomers who are going to die sooner.

The difference is 1%, though. Millions of people isn't a small amount, but considering how the country had to adapt before to growing and shrinking classes of population before it isn't going to be catastrophic, and like I said, it is likely the current 40-50 year olds will live longer and fill out the healthcare market for current boomers.
Not any given quantum computer -- Scott Aaronson debunks the D-Wave "quantum" annealers that aren't actually shown to be harnessing the quantum power.

IBM's machine by contrast is a genuine quantum computer -- the kind Scott Aaronson would probably have no problem with. But the number of qubits is too tiny to do anything interesting.
Although a HEPA filter can be very helpful, it does not remove most of the pollutants in car exhaust (CO, NOx, SOx).
From what I've heard this is false, since for large javascript and css libraries the parsing is faster with minification.
Dude, seriously...you have to stop peddling this ebay recommendation. No one is going to be competitive with data purchased on an auction website.

In case anyone is wondering where they should actually get data to be competitive, I can personally speak for these two:

* Nanex NxCore

* CBOE Livevol

I haven't purchased data from here, but I have heard it well recommended from people I trust:

* TickData

* QuantQuote

There are likely others, but bear in mind that the higher the data quality, the higher the price. For most strategies you'll likely want vetted intraday data, preferably at minute resolution or lower. Tick data is better, but it's going to be huge (my drives are near 100TB). You can reformat it into custom bar sizes if you have data on the actual trades/quotes.
Cool, thanks, that's what I was hoping to learn about.
Have you ever tried sales? It should be fairly easy to get a sales job at any retail store near where you live. Spend a year or two getting good at it, then get hired as a technical sales engineer. Sales is a versatile skill and somebody with both sales chops and programming skills is hard to come by.
> Anyone have hard numbers on if/by how much quants outperform old fashioned techniques

From the article, "In the past five years, quant-focused hedge funds gained about 5.1% a year on average. The average hedge fund rose 4.3% a year in the same period."
IMHO there's nothing inherently wrong with a cyclist "running" a red light. Cyclists are likely to be more aware of traffic conditions than motorists, and they have a strong interest in ensuring intersections are clear before entering. As with anything else, judgment matters. It's unfortunate that occasionally motorists will be sitting at a red light when they see a cyclist carefully approach the intersection and cross when it's safe to do so, rather than when the light turns green. That experience will be frustrating, but they'll have to get over it.
This saga goes back to Sun Microsystems and Apache Harmony. Harmony, as originally announced was to be an Apache 2.0 License cleanroom reimplementation of the Java platform, complete with the standard library and a VM [1]. There was a lot of confusion [2] going forward, because copyleft folks like GNU were working on Classpath, a similar project, under the GPLv2, and none of that code was license-compatible with the Apache License. This was one of the high-profile catalysts of the harmonization of open-source licenses that happened later, contributing to the future GPLv3.

Harmony ran into plenty of other challenges, but despite the odds it managed to produce a working J2SE 5 implementation. It was speculated that Sun was theoretically okay with a copyleft open source Java, but not one that wasn't copyleft, like Harmony. Specifically, they laid out conditions in the license for the Java Compatibility Kit, the conformance test suite needing to be passed to claim that you're "Java", that disallowed certain "Field[s] of Use" i.e. natures of deployment [3][4].

The "Field of Use" restrictions that Sun has imposed restrict software certified with the TCK to "general computing devices" which would for instance restrict use on kiosks or mobile devices. [5]

The Field of Use restrictions limiting J2SE 5 implementations to "General Purpose Computing Devices" and excluding special-case appliances, kiosks, mobile computing devices and other interesting applications constitutes an "additional restriction" that would be unacceptable to us (the ASF), and equally to the FSF (by the GPL's no-additional-restrictions policy). [6]

Oracle initially supported Apache on the matter, but reversed their stance once they bought Sun [7]. Reading Sun's Field of Use restrictions heavily insinuates that covert, embedded, non-copyleft deployments -- like the future Android, a mishmash of old Harmony code, various other open source code, and closed source code -- are the exact kind of application they were hoping to curtail. Instead, Sun released OpenJDK under the copyleft GPLv2.

When I was a homeschooling parent, it occurred to me that kids in public school were "done" when the school year ended, even if they had not read every page of every textbook issued to them. Up until then, we had been struggling with this sense of failure or something for not finishing all textbooks or whatever. After that, I began deciding on certain metrics for "done" and then coming up with small rituals to give us all closure. When they were no longer below grade level, I had them pack up the phonics program they hated so I could mail it to their cousin. That way they knew they were "done" and could be happy with it.

You can do whatever floats your boat here. You are probably the best judge of which pieces have residual value worth preserving in some manner and which things are just basically leeching your time, energy, mental space and hard drive space (or whatever).

At one point Disney acquired the movie rights to "Myths of Miami" for Clive Barker who was going to make a "Bloody Mary" movie out it similar to his "Candyman" movies, so presumably it is a work of fiction. But like how "Candyman" highlighted the real horrors of housing projects in addition to the supernatural elements, the movie presumably would have highlighted the real problem of homeless children.
Yes. I'm not sure what your point is. Do you mean "they already pay a lot of tax!". I think things like this:

https://en.wikipedia.org/wiki/Double_Irish_arrangement

Point to the fact that global corporations spend a lot of effort making sure they get away with paying less than they should. If there was a fair taxation of corps at the level they should be taxed, they would be paying more. Obviously the corporations keep getting bigger and richer, and the 1% wealthier, yet we see countries struggling with welfare state. Doesn't seem right.
> In California at least, it's technically a motorcycle if it goes past 20 mph

No longer true! New laws [0] went into effect at the beginning of this year. There is now such a thing as a Class 3 e-bike that can provide assistance up to 28mph. (I find that's about as fast as I want to go anyway.) When I have to mix it up with cars, the extra speed is a big help.

As for weight, it's really a matter of how much money you want to spend. My e-bike is a converted touring bike, with an EcoSpeed mid-drive, and the weight is very reasonable. I usually bike in to work using leg power (there's a shower at the office) and cruise home with the motor in the evening. There's probably somebody building e-bikes that are also good bicycles; if not, do your own conversion. -- Oh! I just went to the Gigabyke web site. Those aren't e-bikes; those are electric mopeds! Maybe technically they can get away with calling them e-bikes, but they obviously have much heavier frames and wheels. 180 lb, yikes! Okay, I just weighed my bike, and it's 54 lb with battery -- certainly not light by bicycle standards, but entirely tolerable for pedaling.

My bike has a steel frame, so I have no trouble with traffic light sensors. I'm very surprised you do, with 180 lb of metal underneath you!

Have you considered going back to school to get a degree in something else that could land you a better job?
The question I have has several parts, but fundamentally I wonder if the housing supply could even be increased enough to materially affect housing prices.

Not saying that the housing supply isn't excessively restricted, but how much can restrictions be decreased and how much difference would it make?

An analogy is building freeways to relieve traffic congestion. What regularly happens is that additional roads or adding lanes to existing roads provides temporary respite from traffic jams. But before too long the roads are jam-packed again, the problem isn't solved, just have more cars clogging traffic.

I suspect adding more housing won't lower housing prices, just bring some more people into the area. BTW this is what's happening here in Portland OR, where a building boom has been going on for years. The area population has increased, housing prices are still out of range for many people.
Most communities will be filled with e-bikes long before they get a subway.

There are a few reasons.

1. Almost all buyers are institutional funds or individuals with the means to trade as well-informed investors. To put it succinctly, they're in it as serious business, because it's incredibly expensive. They have no incentive to make the edge they just purchased for five - six figures public.

2. These vendors go to various lengths to protect the data, including steganographic "trap streets" to identify the account the data belongs to.

3. There are significant legal liabilities inherent to releasing the data without a redistribution license. You agree to these explicitly by buying the data.

I agree, the stigma is a bummer (though from my point of view not unwarranted; my dad has never walked the same after his accident).

I'm fairly excited about the Arcimoto SRK[1], which is supposed to be available in small quantities this year. It's supposed to be snappy and stable, goes up to highway speeds, and should be a fair bit safer than a motorcycle with the frame and roll cage. At $12k base, you're definitely paying a premium for the electric aspect, but I think it's reasonable. It's at least close to electric motorcycles (like Zeros[2]). How the weirdness of a three-wheeled vehicle (I see them around, but not often) will stack up against safety stigma remains to be seen.

One reason Japanese women don't have children because they are forced to quit their jobs if they have a kid. Letting these women keep their jobs and providing great childcare is one way to help the economy and encourage bigger families.

The section of the article labeled "The new world of work" discusses this issue, although it doesn't go into much details about the pressure on new mothers to quit their jobs.
I'm glad the author likes hers, and it enables her to commute.

I don't care who rides what on a street. What I do care about is people riding them on small narrow paths made for cycling at best speeds, at 24-28 mph. As someone who raced for 10+ years and still rides 120ish miles a week, I don't even ride that fast around bike paths. It's just too dangerous with joggers, strollers, kids on bikes, whatever. When I see e-bikes zip past, I don't get jealous... I get pissed off. I can drop into my small cogs and ride that fast too - I just don't because it's dangerous.

And on trails, I'm sorry - I hold the stance that you can just go find a motocross trail. Mountain bikers put too much effort for too many years into getting what few trails we have built, and inexperienced people on motorcycles do nothing for keeping those trails.

So, if you want it to replace your car, then great, have it. Whether you just want to be eco-minded or got yourself a DUI - I don't care, have fun. But stop trying to use it in places we've fought to get for bicycles.

I am not saying Dark Matter is something that actually exists that cannot be ruled out by other explanations (a revision of GR would be ideal IMO), just that this phenomenon makes the approach much trickier.
That's the sort of thing I'm talking about. Good implementations of known-good crypto.

I don't doubt that Google's trying to come up with new, novel cryptographic methods as well, but those take a long time to develop, test, and get reviewed. RSA didn't show up over-night and SHA3 has taken some time to get ready for production.
The pieces of knowledge I learn on HN never ceases to amaze me.
My point is that data is not competitive. If you give me an example of a strategy you use with that data, I'll illustrate the issues with using data at the resolution ebay sells (to say nothing of things like survivorship bias...).

If you insist on data at this price point, why not just scrape Yahoo Finance? There are literally GitHub projects that obviate this for you.

This is a myth which seems to have cropped up recently among the American right wing - that Japan is choosing its population decline as a show of defiance against multiculturalism, and that it would somehow rather die off than taint its racial or cultural purity, or that it has some magical "solution" involving "automation."

Japan doesn't, by the way, plan on avoiding immigration. It's doing just the opposite, trying to make it easier[0,1] for skilled foreign workers to immigrate, because they may be xenophobic, but they're not stupid. And most of those immigrants are coming from other China and other Asian countries, not Sub-Saharan Africa.

Don't make Japan out to be a martyr for your anti-immigration agenda. That's just another form of Orientalism.

True, CO2 capture from power plants and cement kilns is not yet reality.

That said, this process should work (if perhaps less efficiently) with less pure streams, since it should just depend on the partial pressure of CO2. Other gases like oxygen and water vapor should just be spectators in the process.
