Something I've been wondering about for a while now... Would it be possible to train an algorithm to identify similar characteristics of data from different schema? Looking at the actual data, I mean, and inferring a translation table or the like?

I have a background in data engineering and don't really know where I'd get started. But if you could figure out a way to throw differently schema'd data at an algorithm and have it try to create a universal schema, you'd be wealthy.

There would be a ton of challenges, but the problem you described seems like a societally valuable one to solve.

The customs union is a dream, it even makes dealing with countries outside of the EU much easier

How does imposing high tariffs and onerous non-tariff barriers make dealing with countries outside the EU easier? The advantages of the Customs Union for internal EU trade are clear, but this is the first time I've ever seen someone argue that it's advantageous for external trade as well.
They're not included in 'unemployment' as commonly cited, but they're regularly counted.

The labor force participation rate describes how many people of working age are trying to work. 'NEET' stats remove from that number education or vocational training students.

And economists use multiple definitions of unemployment accounting for many different things. U3 is commonly cited, but misleading for this purpose. U4 captures people who want to work but assume it isn't available, U5 captures other unattached workers, and U6 even adds part time workers seeking full time work.
I have a question about this.

Articles like http://blog.llvm.org/2011/05/what-every-c-programmer-should-... have convinced me that even if C or C++ reads logically like it is safe, there is a possibility that the compiler can rewrite your code in an acceptable way according to the standards such that the checks that are clearly visible in your code disappear, opening up the very problems that you thought you were protected against.

Is there any possibility that after an aggressive compiler gets done with inlining and optimization that that could happen here in some way? Can it be proven that if the compiler works according to the standard that this won't happen..even if the programmer accidentally trips on undefined behavior?

A while back i was in a hostel in England. I met someone who claimed they were an IBM consultant. After testing his technical prowess verbally there were a few holes but he was very apt. He seemed legit or he was able to fool me. I always wondered what an IBM consultant is doing in a hostel unless he is from India and he wanted to keep his cost down. England is pretty expensive. That is what i was doing. This doesn't mean he is ineffective at his job. It just means there was an Indian person claiming to be an IBM consultant while staying in a hostel. :)
The last few XPRIZE announcements have been really confusing to me.

I don't take any issue with the sentiment; they want to advance specifically commercial domains by incentivizing them to accomplish moonshots.

The problem I have is that the moonshots (quite literally in the case of the Google Lunar XPRIZE) are so ambitious that the only people that have the resources to even come close to accomplishing these goals would never be interested in prize amounts this small. They would almost definitely end up losing money with the purses the size that they are and quite honestly winning an XPRIZE just doesn't carry enough prestige to counter the capital losses.

The amount of R&D needed to get a robotic avatar to the level proposed here is staggeringly larger than $10mil.

I just don't see the point.

I've always thought of "ambivalent" as indicating fairly strong mixed feelings. I think it's actually the word you want. For the first meaning, I would go with "indifferent".
I found this graph helpful[1]. U6 has come down along with the other unemployment numbers, but it also shows how historically bad the recession was. For those affected by it, that's six years they will never get back - they might be "employed" now, but with prospects that are far worse than if the crash hadn't happened.

I read the concern more as "what do you do to stop someone from cURLing an .iso a million times from someone's S3 account".
I’m pretty sure this was the exact example of “rent-seeking” in my economics textbook.
If I build 92 of these things and they communicate with each other over sockets, files, streams, or messages, how does Coherence (a) help me visualize and debug that network, (b) transition the processing graph to a new state safely (blue/green deployments to one or more collaborating components)?

The problem that I have with these Serverless stacks is that they all demo pretty well for the trivial case of "it sends emails / transcodes video / puts files in S3" but then jump to "run your entire business on this" without clearly showing how its possible to do that with a complex system.

I find this a really flawed logic, just because someone doesn't have an alternative doesn't mean he just accepts whatever is thrown at it. There are many situations where "I don't know" is acceptable.
all the alternatives are fairly mediocre, I tried them all. The closest thing is google spreadsheets, which really is not designed for RDBMS / light database work. You can read my review on alternativeto.net as well.

That's exactly why I described how you could build a system that accounts for that.

>thousands of pages of internet arguments with those best at brigading or astroturfing

Brigading on a platform for direct democracy is a feature, not a bug. Astroturfing and most other forms of uncivil discourse can be pretty much eliminated by tying your account to your identity and with a few fairly basic moderation rules.
the question is just moved from 'what is the value' to 'why are you willing to give'.
There are. AFAIK, it's never been applied.
> It's not. You want to know the most probable value of A.

Nah, it's really not that simple. When I've done this in the past, I've needed both the mean (which is the mode for Normal distributions) and the variance, so I can make confidence ellipses. I don't just care about the most probable location.

I already have a set of techniques for working with Kalman filters. The only reason I would want to understand applying the Bayes' theorem in this context is if it offers insight into a wider class of problems (non-Gaussian PDFs) or if it helps me communicate with others. In both of those cases, I'd like to understand the thing first before I hand-waive the denominator away.
Yes, but there will be a liquid market in such nodes. Finding them will never be a problem.
I have no idea why I'm replying to you, because as I noted I don't really think you're interested in anything except confirming your bias, but:

People are listing "telling the time (duh)" because it's OBVIOUSLY a watch. I guess I could assemble a face that doesn't include the time, but I certainly haven't wanted to. Obviously I consult it for the time several times a day. Obviously, that's the primary role of a wristwatch.

I suspect people here, like myself, have omitted "telling the time" when outlining reasons the Apple Watch is useful are doing so because, duh, it's a watch. It tells time.

Incidentally, there remain no small number of manual-wind watches in use that require daily winding. Are they also examples of the worst watches ever made?

There's an extraordinary difference between you being entitled to a company being forced to exist to serve whatever arbitrary need or approach you wish, and there being an open market such that a competitor can set up shop.

If you were entitled to alternatives, that means the tax payer has to reasonably fund every possible alternative that could exist, or at a minimum a vast array of them, and most likely at perpetual losses. It'd be extraordinarily dumb and would become an epic cost for the government and would breed corruption (failed businesses, bleeding vast red ink, perpetually subsidized no matter what they do).

No, but if you're someone who wants to see Bitcoin succeed then you probably don't want to use a scaling solution which only works if you assume Bitcoin will never achieve mainstream adoption.
There's no rule of thumb that git beginners start with their own repositories. Maybe they clone a big project like linux or git, or start working as a junior dev at a company with an established code base. It's important that git work sensibly by default without you needing to know there's a --simple.

Also --oneline --graph can get really nasty on even small repos, particularly those made by beginners who are doing redundant merging.

But yes, all of those are technically solvable, e.g. git itself could fall back on the simpler view given some heuristic, but I think given the principle of least astonishment it makes sense for all the commands to work sensibly by default whatever the complexity of the repo.
This is precisely it.

(Employed / seeking employment) is the U3 employment rate - it's a perfectly legitimate statistic for understanding how the job search is going. When economists want to count the temporarily discouaged, they use U4. And when they want to count those not working for other reasons, they use U5. It's annoying that we treat U3 as "the unemployment rate" for political discourse, but it's a perfectly reasonable metric for economic analysis, and I wish people would stop pretending it's some kind of trick.
But what happens if a watchdog has an outage? I need multiple backup watchdogs then, and no watchdog will work for free. So I'm now paying multiple entities to securely transact money to other people that themselves also need watchdogs to watch their channels. This sounds not like it will result in low fees. Transaction fees, maybe, but overall fees including middlemen will be quite a bit higher.

Exercises, I want Exercises, no I need Exercises.

In order for me to learn anything, I need some form of "homework". If you want to teach me a new language, a new framework, I need to "get my hands dirty".

I'm pretty sure inflation under these circumstances occurs independently of further fed intervention, the classical economic theory being that competition for labor (under low unemployment) drives an increase in salaries unaccompanied by an increase in productivity, resulting in inflation

Oh cool, I didn't know you could do that.
TL;DR; use smart pointers, RAII semantic and STL containers/iterators. Though, I'd have a few criticism...

> Rules to ensure memory safety

These "rules" only protect you against object's lifetime issues, not overflow / underflows, and other kind of memory issues.

> ‘owning’ pointers are obtained only from operator new

no, you shall be using std::make_{unique,shared}(...) which will protect you against leaking memory if exceptions are raised.

> Calling a function passing the pointer as a parameter, is ok.

Correct, but you can still shoot yourself in the foot. Best is to pass a [const] reference to the function called.

> This only leaves us with functions such as strchr()

Don't use C API. The STL should provide you with enough API to use the proper C++ types, either std::string or std::string_view in C++17 if possible.

> and also prohibits C-style cast and static_cast with respect to pointers

IIRC, you can't static_cast<> a pointer, you'd have to reinterpret_cast<> it, which the document does mention.

> For arrays, we can always store the size of the array within our array collection, and check the validity of our ‘safe iterator’ before dereferencing/indexing

use std::array.

You shouldn't blame deluge of new laws on the users. It's kinda like victim blaming as though they made the laws themselves. Instead of asking "what caused governments to make new regulations" instead ask "what caused governments to use regulations instead of alternatives (including doing nothing)". You point out problems, but that's not fair to say that they caused the specific solutions more than the solution presenters themselves.

> Yes, but there will be a liquid market in such nodes.

How? You need to trust those nodes to provide not only a secure but also reliable service that will be online 24/7. A single outage, even if its only a minute long, can possibly lose you all your money in all channels. This means that centralization will happen almost immediately as high-availability is a very complex topic that is not achievable by amateurs. Especially when you are talking about more than 5 nines and actually mean 100%.

I suspect you don't know this, but: the Watch provides tactile "nudges" about turns one way or the other. For more complete directions -- and, obviously, a map -- you still have your phone, which is orchestrating the navigational prompts on your wrist.

It's useful, when navigating, to be free of the need to stare at one's phone or a map the whole time. That's the boon here.

But, again, I note you're the guy who seems really invested in hating the watch -- even to the point of dismissing as invalid reasons another poster enjoys it! -- so it's not clear why I'm replying.
Thanks!

Our cold-start times have a way to go, they're around 1 minute on the first invocation of some set of binaries and less than 20 seconds on subsequent invocations.

We've done a lot more work on optimizing the subsequent invocations time, including even running a forked version of docker (it reduces docker save time by 100x or more)

This is a primary scenario for us though and there's a lot of room for further optimization. We'll be posting figures and progress regularly post-launch.

EDIT:

I missed some of your questions, we need to upload your project's binaries only (not package manager binaries). So languages with larger binary sizes will have longer cold start times. Overall this comes down to the factoring of the project though.

We should be able to support Go since the binary is static linked, but it has less portability than other managed languages so we've targetted those first as lower hanging fruit.
The last time the US was at or near full employment per the U6 was 2006-2007, when it hit around 8%, courtesy of an extreme housing bubble.

Before that it got below 8% in the late 1990s because of an extreme stock market bubble, which was fleeting to say the least.

Not very good comparisons frankly.
Early adopters are beta testers ;)

I think until about 2014 (3.4) Python 3 just wasn't really ready. Then maybe it took another two years for library and tooling support to firm up around that. In 2016 I did start a new project, but a mix of familiarity and gevent support kept me on 2.7.

Also, until recently the runtime had no real advantage over 2.7, but there have been some incremental improvements (dict shared keys and so forth) that are a win you get in Python 3 for free basically.

Working on a new project in 3.6 now and it's looking good so far.

That's enough to handle the blockchain size increasing by one order of magnitude. I just talked about a scenario where it could conceivably increase by 3.

His explanation, actually first given by Michael Faraday in 1859, was later found to be wrong. According to a 2005 article "Why Is Ice Slippery" published on Physics Today, even when a layman is wearing a pair of skating blades, his/her weight can only lower the melting point of water by about three to four degrees. Yet skating is still possible when the temperature of the ice surface is as low as -30 degrees Celcius. Pressure melting cannot explain why skating blades can make ice surface slippery enough in this scenario.
> I am skeptical of this pervasive claim because it is effectively unfalsifiable; claiming kids from Asia are “just good at tests” and that thus we don’t need to worry about our education system ignores the fact that most European countries do better on standardized tests too (the UK, Germany, Finland, etc.).

That's not what I said (though you may be commenting on my response and not responding directly to me). I claim that the Chinese and Indian systems have a lot more memorization than the US or European systems and that they often produce students that excel at a skill that doesn't always correlate (but isn't uncorrelated either) with what I want STEM graduates to be. I freely admit the US system is bad, if not terrible, but I'd rather look to Europe for inspiration than Asia here.

As far as I'm aware, if you stay within the confines of smart pointers (and don't drop down to the raw pointer it owns) you will never encounter undefined behavior. You may have crashes if you try to double free something, but these are defined to crash rather than letting the compiler optimize out checks.
