I know several top-level mathematicians (International Math Olympiad medalists) and not all of them are working as Quants. Some of them compose music, some of them are working as machine learning experts, VC funds, etc. They may be slight outliers but it's possible to do whatever you want as long as you posses the intellect and drive. I think Mathematics definitely help with developing your logic skills that are applicable to anything.
> Helping businesses collude to drive up prices and increase profits really should not be the role of government.

Well, that's one way to look at it. Another way is to say it stabilizes a strategically important sector and establishes a minimum wage for dairy farmers. I'd rather pay more for milk than have desperate farmers killing themselves at record rates. There's a societal cost to that as well.
The funny thing is that Google was the first to introduce Differential Privacy to a production service into Chrome . Also differential Privacy was first created at Microsoft. Apple just followed Google and publicized it much more
what is even more important is that your infrastructure should be consistent and self documenting (thanks to Configuration Management this is really easy).

Having a solid infrastructure with failure mode and behaviour that is expected saves a ton of hassle and makes ops "easier".

most of the time, having everything redundant to the level that stuff doesn't break is simpely not possible, so its better to make it break reliably. (a good example of this is hard crashing applications on errors which could manipulate data, instead of trying to continue. This makes your failure behaviour consistent across the enviroment).

> With regards to stability, I had no issues with either AWS, Softlayer or Hetzner. However, when running a long task (the benchmark with Tensorflow-GPU) on GCE, the job abruptly stopped after a few days without showing any errors, and I couldn’t figure out why. A repeated attempt also resulted in the same failure.

I encountered same error with google cloud ML engine. No errors on warning when shutting down. Any idea why?
That would depend entirely on the stock. I'm sure there are many, many companies whose stock trades at less daily volume than BTC. Actually, I'd think few companies' stock trades at BTC's volume.
I suggest that you build on top of the Riak Core from Heinz Gies. That's what we are using in some of our new projects.
Because it's better than being on a trajectory where BTC hitting $1m is a real possibility. That world will be terrifying, and it's important for us to think about ways of mitigating or stopping it.
I think they just simply think "how can I minimize what I pay in taxes". They might think of police, roads, etc but that's after they finish thinking about themselves and their own accounting. So it means pretty much they never think of it.
My memory of reading Bamford's book was that it was an APPROVED proposal, which was made obsolete by the Cuban Missile Crisis. The DOJ approved that plan, and many of the people involved in that are still on the scene today. But, I read that book a decade or more ago so maybe I'm misremembering.

And a possible 1a: Tell them you'll be happy to give them your source code, and everything else to boot, if they'll buy your company.

This way you get to jump straight to your exit, and can maybe also structure the deal so that you and your employees get jobs at the BigCo (if you want them). Feel free to set the selling price as high as you like -- they would want the deal more than you would, so you have a lot of leverage in the negotiation.

And if they balk? Hey, they asked for terms to see the source code, you gave them terms! It's not your fault if they don't like them :-D
Python only because it's the string class that I've used that always has everything I need. QString from Qt is pretty good, too. std::string is, like you say, painful. Since QString exists, works great with a long history, so why is std::string so limited? Design-wise, I'd say the few changes which QString has had demonstrates the solidity of the design.

Off the top of my head, what I use frequently (and which is unavailable in std::String) is:

- replace(search, new). std::string can do it, but first you have to find the index of the start, then you call replace() to replace a set of bytes. Too low level.

- endswith() and beginswith() are surprisingly helpful. endswith() in particular. s.index("prefix") == 0 is pretty clear, but s.index("suffix") == s.size() - "suffix".size() is not very clear.

- toupper()/tolower()/isspace()/isslanum()/isupper()/etc. are not something you use every day, but you really don't want to have to write proper handling of every language's idiosyncracies yourself, and it's not worth it to find a library, so probably only European languages will work initially.

- proper unicode handling. std::wstring (UTF16) is not it (to be fair, that wasn't clear at the time of design), plus I don't think it works well with either Microsoft's or Apple's UTF16

- making a string from a number. QString does this well, Python 2's str(num) is not really flexible enough. I don't want to have to create a stringstream just because I need a numeric string.

- create a string from a printf list. I know stringstream is supposed to do that, but I never seem to be able to do exactly what I want (e.g. %.3f), and regardless, I never can remember the correct syntax for the modifiers (e.g. hex(), precision()), despite it appearing like it ought to be obvious.

I pretty much expect all the above in a string. std::string is basically a veneer over an array of bytes. Maybe that was okay in 1998 when it was designed, but the first thing I have to do is add all that in now, every time I do anything UI-related with text.

I also would like split(), it makes simple parsing a lot easier.
> These are the arguments underlying an “open science” reform movement that was created, in part, as a response to a “reproducibility crisis” that has struck some fields of science.

Because social scientists continue to make giant claims that fail to be supported by the evidence, and those claims are used to enact sweeping policies based on quackery.

Stereotype Threat. The Implicit Association Test. The Bystander Effect. Power Posing. These are examples of "science" that is based more on rhetoric and emotion than reality. But it is having real effects on policy.

If your claims are made up and based on shoddy principles, they deserve scrutiny.

> objective knowledge is not enough to resolve environmental controversies.

This article is literally trying to build a case of "feels" over "reals". Transparent objective facts should guide the debate, not twisted political rhetoric masquerading as "science". If your position is incorrect and does not match reality, it must be dropped, even if you would prefer it to be true to push a point.

I think you're conflating several different things here. Their vulnerability to hackers is not at all related to the extent to which they are willing to cooperate with the US Government or to exactly how their GMail ads work. You have to define exactly what your threat model is, and no service can really be the best at all of them. It's perfectly consistent with the worst interpretation of your other assertions that Google is still the gold standard for making sure that no hacker can ever compromise your GMail account, reset your passwords to your services, and hold your data and accounts on other services hostage.

Edited: [long paragraph about vfx but the reddit link covers it exactly]

I came across the same model when working with an architecture firm and it makes me wonder if maybe all client services, given the power disparity and need to please, isn't like this. Architecture is far more regulated of course but in the design stages I heard from people that were pissed that they were going to take a bath on a project (and look bad and have their numbers look bad) because an executive wanted to make sure that client was happy (such that they cut a mansion renovation down by 50%) or won't do an add service after a client completely throws stuff out the window and changes the scope of a project.

At least in VFX there was OT and DT. I felt bad for architects that were highly educated, with subsequent loans, and working a lot of overtime but not being compensated for it.

I'll stick with IT, even though that has its own issues.

It sucks that this may be happening in farming, which isn't a 'sexy' industry like architecture or film, but our greater society as a whole seems more cutthroat and bargain-driven these days.
Nothing has that value if you look at a long enough time span. Gold, a traditional store of value, gained >100% and then lost >50% in the course of a decade.

Obviously this is not even noise compared to bitcoin; but my point is that bitcoin has shown to be an exceptional store of value for a long term hold.

Beyond that, I think most people who believe in bitcoin as a long term store of value expect that when it reaches a mature global-level market cap; the swings should be less severe.
I have not run into issues like this, but I would at least make an attempt to meet them in the middle. NDA's and the such are not something I would be confident in, particularly given that this customer can throw a lot more money and effort into legal.

Regarding meeting them in the middle, I would put together a presentation that describes how your algorithm works at a high level. I'd do your best to split the balance between being transparent and focused on the customer, and not divulging what you consider to be differentiating parts of your implementation.

If you get push back for the above, I think you're dealing with either brain rape, or some pretty unprofessional contacts in your customer's organization. If it's the latter, you should do your best to navigate around those contacts.

> For instance, when the EPA was preparing to set new limits on particulate pollution in the 1990s, industry groups pushed back against the research and demanded access to primary data (including records that researchers had promised participants would remain confidential) and a reanalysis of the evidence. Their calls succeeded and a new analysis was performed. The reanalysis essentially confirmed the original conclusions, but the process of conducting it delayed the implementation of regulations and cost researchers time and money.

If the data had been open from the start, this wouldn't have been a problem.

Also, why don't we just sow an equal measure of uncertainty in the studies showing that these drugs/chemicals/externalities are safe? I bet if you demanded that the pro-industry studies should be "sound," you would discover a lot.
My understanding is that the problem is not really with pacemaker/corosync. Those tools also are always consistent as ZK/etcd/Consul. There is also SONITH to make sure the node that goes down can't cause damage once it is back.

The problem is not these tools, but implementing what is the right thing to do during an outage or even properly detecting one (what happened with github). Your solution might work 99 cases out of 100 but that remaining 1 case might cause your data loss.

When there is a human required to do the switch it typically he/she can investigate what happened and make the right decision.

It's theoretically possible to have a foolproof solution that always works right, but that's extremely hard to implement, because you need to know in advance what kind of issues you will have, and if you miss something, that's one case where your tool might make a wrong decision.
It's great when it works as expected. When it doesn't... then the fun begins. I've found it quite fragile, components versions sensitive, configuration sensitive, etc. Most of the time I've seen Pacemaker gone crazy Pg itself was happy to cooperate once the Pacemaker was out of the way. The unknown/weird Pacemaker failure modes were a real (and scary) problem.

I guess the lesson here is not to rely entirely on some HA black magic and always have procedures in place for the 'HA black magic failed us' moments. And team trained to deal with situation like this. It's only software so it will break sooner or later.
Yea they completely brushed over the likes of VRBO and other competitors.

I think the biggest similarity is consumer mindshare and the art of turning your brand into a verb.

Even if I'm ordering a Lyft, in conversation I'll say I'm "ubering".

Likewise when booking an "AirBnB", I'll browse all sorts of alternative sites just to spot check locations/prices/etc.

The real limit to the market is how many players are in the game.

Remember when Austin Texas had a fingerprinting law that prevented Uber/Lyft from operating inside the city? There were a million and one alternative services, but generally both drivers and riders would recommend and use one or two based on personal experience/word of mouth recommendations. (ie- Ride with a driver that provides a good experience and who talks about which ones he or she uses and likes, then you will tend towards those apps rather than the smattering of others)

In markets like these where both the buyer and seller are using a 3rd party to accomplish a secured transaction, there seems to be only room for a few. This generally is down to mindshare of both the buyers and sellers, which comes down to marketing and getting your name out there.

Uber and AirBnB are in the same boat. They have the market's mindshare and brand name recognition... and thats about it.

Yeah, which is why many will "break ranks" and include a higher transaction fee even if there is a previous spend in the mempool.

The Masterpiece Bakery SCOTUS case begs to differ. The bakery owner is arguing expression whereas the couple are arguing discrimination. Actually you should read about the case; I feel like you'll learn a lot.

I guess we're both right though? It's not like some rights are never balanced against other ones, but some are more often balanced against each other than others. But expression/religion vs. discrimination is a really common balance, and we get it wrong almost every time.

But I do think I have a right to be free of some speech in some places, and most people do. When protests are organized they have to register with local governments. They don't go into homes, they don't go into workplaces, they don't go into schools or churches. Aside from homes, these are all relatively public places, but protestors don't have a right to protest in them.

In other words, this is the basic concept of negative rights. Positive rights are things like freedom to practice religion, but negative rights are things like freedom from unwarranted search and seizure, "freedom to" and "freedom from".

I also think there is a right to be free from racist speech, though it hasn't been recognized (maybe it has re: dignity). We have a right to be free from violent and threatening speech, for example, and I think racist speech is on the spectrum of violence -- if only because the history of racism is overtly violent. But aside from that, the Supreme Court has (kind of) recognized a right to dignity and racist speech in the public square clearly impugns Americans' right to dignity on a fundamental level. See https://supreme.justia.com/cases/federal/us/576/14-556/opini... .

Fair enough, but it seems arbitrary and capricious to single out debt collection as the one and only business function that you're not allowed to outsource. Just like accounting, payroll, advertising, lawyering, etc., it requires a specialized body of skill and knowledge that many businesses would rather not have to develop in-house.
This is a false dichotomy. Read Matt's testimony.

We can have immediate results and reduced errors from electronic voting while simultaneously having a perfect, affirmative paper record.
Well, that's what it is today. But if BTC has no fundamental value, you might argue the price fluctuations are the price-discovery function of markets screaming "there is no correct price because there is no actual value", or something like that.

All other fiat currencies have some fundamental value. In the past they were backed by gold. Most common today, you have to pay your taxes using them, which means for example everybody who owes US taxes needs USD.

Does Valve really needs more than 0 confirmations? double-spending doesn't seems like a big issue for them since Steam is DRM and they have some level of control over the software people have in their libraries (and total control in the case of online games). If the concern is whether some people would just download games, double-spend before getting one confirmation and then keep Steam offline forever (or copy the game files from the steam folder), I think people can already do something similar as they let users "return" games during the firsts 24 hours after the purchase.

> Nothing can grow at such an insane rate and be a stable, long-lasting thing.

That sounds like common sense, but common sense is not neccessarily right.

Imagine a German in the 1920s looking at the price of US dollars in Reichsmark. That can't be true, $1 for 1000 RM? Now 10000 RM? Nothing can grow at such an insane rate. Surely there is a dollar bubble, and it is going to crash.

What our German friend didn't realize was that his own currency was (hyper-)inflatory. USD were not overvaluated, they were stable. The current situation is similar, except instead of our currency being inflatory, the other one is being deflatory - this has the same effect on the exchange rate. It does not neccessarily mean there is tulip fever going on (although, to be honest, I can't disprove that).
There is zero reason to believe that, and I'd even go so far as to say it WILL happen again, and probably soon.

There are solutions being worked on, but they are not ready for primetime yet.
