These 'from the ground up' totally all-new-code approaches to DBs are just a scary proposition. Think of the thousands of man-years of effort that went into building MySQL, testing its codebase, and perfecting it's robustness (fail-proof-ness). What does MongoDB bring that couldn't have 'built on top' of MySQL codebase, and used MySQL transational layer as it's underpinnings. Sure, MongoDB gets all its performance gains from delaying writes to the DB (eventually consistent), caching in memory, and dispensing with ACID, however there is nothing about MongoDB that couldn't have been written to use the DB layer of MySQL at the point where it actually does its writes to disk. In this way, MongoDB would have revolutionized the world rather than mostly "fragmenting" the storage space.

I guess there are those who will say that even using batch-commits, that MongoDB could never have achieved the performance it currently does (by bypassing any ACID) if it was built on top of MySQL. But regardless, why not focus efforts on improving MySQL batch processing performance rather than throwing it all out, starting from scratch, and writing directly to disk. I know MongoDB became a success, but I think that is 'in spite of' their decision to start from scratch and not 'because of' it. Also think of the power that would be available if there were some relational table capability (true real MySQL ACID) right inside MongoDB whenever it was needed, if they were the 'same animal', rather than having to use two totally and completely separate DBs if you need NoSQL and also ACID in an app, which 99% of apps DO NEED, at some point, once an app grows beyond the round-one funding startup-toy phase and MongoDB falls flat in it's RDB capabilities.
I'm not saying to avoid those in C++. I'm just giving that as evidence that writing C++ is more difficult than Go. Sounds like we're in agreement.

> Could be, that you can just mount an extra volume and use rsync, not sure.

You can't mount an extra volume on the cheapskate servers - I tried recently (in order to test my contribution to their open source efforts, of all things...) and only found out after it had shutdown, backed up, and created the new volume.

The backup disk, and the extra one I couldn't mount meant my bill went up to ~€5 for the month.

Would've been nice if on creating the extra volume it said "Are you sure? You don't have a server you can attach this too at the moment" or something.
Publication bias is a gigantic problem for amateur FinTech.

How many hundreds of engineers tried the same thing and won't get an article on the front page of HN because no one wants to read about mediocre performance? I don't want to sound too skeptical, quantitative HFT is absolutely the future, but if enough people try something that's effectively gambling, some of them are bound to succeed, and those people will get dramatically disproportionate exposure.

I have been in an environment, where there is some legacy Perl scripts that run, everyone is terrified to update it even tho it's a PHP shop. I looked at the code thinking it would be a nightmare, but no. It's actually good clean code. So it's not nonsense, some folks absolutely refuse to engage in new adventures. They would be ready to hack all over it if it was node, but Perl? won't touch with a 10 feet pole.
here is a stupid argument for privacy that i just invented based off of the article's mentioning of 1776:

if the british colonists had no privacy, the american revolution would never have happened. troublemakers would have been either nipped in the bud, or never even thought that they could successfully challenge the existing power structure.

what god-fearing amurican is going to argue against privacy when you frame it as a patriotic issue? sure, there's no logic or graceful rhetoric here, but who needs logic when you have emotional arousal?

those of us who have enough brain cells to rub together need to start thinking about how to slam the idiots with arguments they can't get around while maintaining a veneer of nationalism. "you're unamerican if you're against privacy, because we needed privacy to execute the most hallowed event in our civic religion: revolution against the british." that kind of garbage.

it's time to discard clean argumentation and jump into the mud-- it's the only way to make people care about an abstract issue that people have been taught to disregard like privacy.

You're right in that it's hard to create a new billion dollar privacy company. But there are plenty of opportunities to create "small businesses" focused on privacy. Basecamp sized companies. In fact, that's the advantage small founders have now: is to not be big, but be intentionally small.
Another obvious example is actuaries and any number of other analysts in the insurance industry. According to Google[1], actuaries earn an average of just over $97k/year. While this may not strictly be an "investing area," it's a clear target for automation.

The Intel Atom C2000 Series Bug – Why It Is So Quiet
> Take a step back and ask yourself, what is the goal of the FSF?

The name suggests that, but the substance of their advocacy and actions suggests something slightly different; their goal is not to promote Free software, instead, it is to fight against non-Free software.

Which is why they generally argue that licenses which they recognize as Free but which allow non-Free derivatives are dangerous: more Free software is not their goal, less non-Free software is the goal.
This is true for just about any superficial community, which reddit is full of. Clickbait driven logic.
I was thinking about this lately. Can universal health care be solved by the free market, if the free market decides to enforce checks and balances on itself?

That is to say, could someone start a not-for-profit health insurance company that offers excellent coverage for affordable rates, and build it from the ground up with a culture of clarity and transparency? At a bare minimum they should have a searchable database where you can type in "broken arm" and find out what price this company has negotiated for casts, x-rays, and doctor time, and what it will cost you in co-pay.

It seems like insurance companies are so universally bad and corrupt that there would be no trouble signing up a critical mass of users by simply being a little better than the norm, and once it's the biggest insurance provider in the US, start applying muscle to hospital administration.

Yes, I know I'm oversimplifying it. Can anyone think of a way that it might be possible, though?

It's a matter of amounts, not of yes/no. Of course they pay rent and buy food, but in what comparative amounts? If you send half of your money outside the country, where very little of it makes its way back to supporting the US economy, that's worse than if your salary was given to someone who was going to use it all inside the US. If you disagree with that, please provide some numbers for us to use as examples.

Also, please point me to these Americans who save their money. The average domestic savings rate is 5.7% and almost all of that is money stored in US bank accounts and stocks, which in turn is used to help the US economy.

"What is preventing legislation that simply opens borders / trade for filling prescriptions?"

US suppliers sell to Canada at a different price than they sell in the US.

If 'borders were open' - the price in US would go down, the price in Canada would go up, roughly to the same price.

I understand that it seems odd, but I reject the idea that it's 'corrupt' to sell to one country at a different price than another.

Drugs are essentially IP, so it would be like the US selling Canada the 'Superbowl' and then Canada selling and broadcasting it to the rest of the world at a discount.

I think something should be done about that - but drugs are not like most goods. And of course, many goods have different controls and regimes.

Another aspect: it's not really 'free trade' when a government entirely regulates the economy for a good. So when gov of Canada 'sets prices' for a good, it kind of flies in the face of regular trade rules and potentially gives one side or another advantages, so it really doesn't fit well under things like WTO or NAFTA.

Surely we could have some new thinking about this though ...
Incumbent banks have been incredibly bad at creating modern digital user experiences. To analyse my spending, I have to login to my online bank with a fob and various passwords, download statements in .csv format (month by month, no batch download) and plot them in excel. It's not great.

That is certainly true, but it's not as if the shiny new fintech startups are necessarily any better. You'd think it would be business finance 101 to be able to reconcile money that a payment service collects from your customers and then deposits in your bank account with the money you expected them to be collecting, but unless there's been yet another API change lately, none of the services we use support a simple, reliable way to do this.

It's funny how we attribute human qualities to animals that literally lack the neurological capacity. Sharks are not ferocious, dogs do not love you, cats are not independent.

There's nothing wrong with reasoning by analogy, and to be perfectly honest I don't know enough about animals to argue convincingly that cats don't, on some level, want to be alone, but we should understand that having this discussion is mostly just anthropomorphism.
I ended up switching to Emacs after having spent quite a bit of time in Visual Studio, Kate, and Geany (in approximately that order). I've since tried Sublime and Atom, but they don't feel right to me. My '.emacs' turns Emacs into my editor rather than someone else's editor that I happen to use.

Basically: I don't really care about the out-of-the-box environment. I care about an environment that's tailored to my use-cases and programming style. This will cause me to frequently gravitate toward Emacs or something very similar.

I also happen to like Lisp, so there's that. TRAMP also helps considerably for editing remote files, and very few non-Emacs IDEs/editors offer any real equivalent.
Factorio is great, but word of warning, I can't get it running on Linux at a decent frame rate without DRI_PRIME=1 LD_PRELOAD=somepath, which makes it predictably yet horrifyingly unstable.
I think a lot of people get hung up on how humans make decisions, with the expectation that you need to be able to understand the same ideas to perform the task.

Even if a computer can't figure out the stats you mention, maybe it doesn't matter? Maybe just reacting fast enough to what people in the market are doing is good enough? Maybe simple sentiment analysis on articles on Disney around the web is a good enough proxy for share price increase.
> Except all of the actual journalism being done on

I don't believe the journalists are incompetent. I believe there is actual malice there. No amount of incompetance can explain how they always say "muslim ban" and "7 muslim countries" instead of ever referring to the 'Visa Waiver Program Improvement and Terrorist Travel Prevention Act of 2015' [1], where all of those countries were originally classified as 'countries of concern'.

The 'journalism' shows large amounts of malice. It's not just incompetence.

These algorithms are only good at front running the reaction of the market, which is fairly predictable in the short term when a relevant piece of news is published. They are nowhere for making long term investment decisions.

AI everywhere is as naive as software everywhere. It costs a lot of money to develop and maintain software professionally. It's uneconomical to staff an IT team to replace every routine job there is with software.

It will be the same with AI. If you apply enough bright people's mind for long enough, we can possibly automate certain niche jobs, but that's going to be completely uneconomical. You need to pay these AI specialists, and retain them so that you can adapt your algos as the problem moves, and there needs to be more than one in case one goes or is ill. You can easily spend more that the salaries you are going to spare.

Other problems are I believe too vast and open ended for AI to come up with anything useful. What company will be successful in 5 years? What is the right level of renumeration for the management of that company? Where is innovation going next? You really think that AI is anywhere near answering that kind of questions?

AI will shine in similar areas where software shines. Problems that are simple enough to be understood by computer scientists (and that narrows down this vast world quite a bit), and that are broad enough to justify the economics of making high investments to build data, or where there is already ample of existing and relevant data. Driving a car. Cleaning or building a house. Replicating certain hand movements. Things like that. I doubt an expert on a narrow and specialised domain has much to fear from AI.
I wonder how many engineers have replicated the payoff of a dynamically hedged short option without understanding that was what was happening.
That's the WTF for me here. I don't store anything valuable on the Windows 8 PC I run at home, but when I set it up, I remember feeling quite uneasy about the way the Microsoft account and the local user login apparently are one and the same. I assumed that surely it's just convenience and gaining access to the MS account isn't sufficient to give access to my PC - that would be insane, right?

Is this being reported correctly? This sounds completely nuts.

Good luck, and I sincerely hope it works. This time.
There's definitely a lot of incompetence, but I don't think it's the whole story. The fact that the White House explicitly clarified to DHS that green card holders were included, for example, suggests malice.

My question is are the jobs disrupted really stolen..

according to Mr Klarman(see the NYTime article) this automation trends lead to more inefficiency in markets not less and thus give opportunities to some traders to bet long term in the other direction..

Or are those disrupted jobs just getting re-deployed as new trading businesses betting on some long term stuff..
While I do agree with you to some extent, as opposed to gambling, stock market requires technical knowledge. I strongly believe that individual traders stand no chance agains the big players and there may be a combination of luck + favorable stock picks in this case.

Having recently had my first major experience with US law, Im starting to understand (not agree with. Understand) why this happens.

The US civil laws really only apply to middle class suckers. Rich people can use their lawyers to work around it. Poor people are "judgment proof". If you don't have a house, you're working under the table, and your bank account is empty, there's fuck all people can do against you. With criminal law on the other hand...

There's only so many times you can hit someone who's judgement proof before you start wishing you could get them tossed in jail.

I recently had someone who screwed me over from about a very large amount of money. He was laughing at me in the face making sure I remembered that even if I won a lawsuit against him, I'd never be able to collect. He was unfortunately quite right.
> I don't expect my compiler to go ahead and run step 3 first.

You would be surprised[0]. In low level code (in some cases) you'll need memory barriers[1] to ensure the proper order of instructions execution.

Even in higher level code your compiler's optimization algorithm may decide that it's faster to execute step 3 first if it thinks the result would be the same.

Probably because there has been a lot of development in distributed databases in the last few years. Raft is fairly new, for one.

Taking really old code and trying to make it do new things is very very hard. After you've invested all that time and effort making mysql better, it's still a database owned by oracle.

Universal healthcare is already possible.[1] Reducing waste is a noble goal but this is a startling sentence from a health tech startup team.
