Can anyone recommend a MOOC that covers using KDB+ on financial time-series?
Yes, as I said in this comment [1]; my real issue here is lengthy GC pauses, which cause peaks in response times.

Regarding overall performances, I'm not really convinced that the reflect calls affect them that much (there's 2 reflect calls per Read() or Write() call), but I honestly just don't know, I'd have to bench to be sure.
Although, if it turns out to actually be an issue, you can still use Pointer() to keep references to your unmanaged heap and you'll be able to work with your data without GC nor reflection overhead.

Has anyone noticed recently how Russia is clamping down on file-sharing and such? Often in very extreme draconian ways.

I was wondering why does the Russian government give a shit about copyright infringement, most of the content being infringed upon is not made in Russia, so in a way infringement means less imports for them.

I'm not usually a conspiracy nut but I genuinely think they are using piracy as a scapegoat so they can just clamp down in general and establish a more totalitarian regieme. They are also clamping down on gay people, feminists etc.

That + keep their American buddies happy I guess.
That's a terrible argument.

You're talking about public debt, which is a small fraction of all US wealth holdings (household + corporate + government), and can be trivially managed. Further, unlike a lot of countries, the US has significant spare taxing capability (it rests in the middle tier globally on taxation). The US could easily raise $200 billion in new annual income taxes on the top 25% and not miss a beat - that single move alone would handle any potential issues from the public debt cost. Or better yet: the US can constrain its spending growth (as it has been), allowing income and assets to continue to outrun the problem.

And of course the US owns the global reserve currency, which enables it to export inflation to the rest of the world as a means to reduce the domestic hit of things like QE (which is why the Eurozone's QE hasn't been as effective). When the US uses the dollar to improve its fiscal circumstances, the rest of the world foots a big part of the bill. While that's sort of like cheating, it's an advantage the US possesses that nobody else does.
I know it's anecdotal, but what you describe doesn't seem to have anything to do with the world I live in. You really need sources for a claim like that.
If "gold standard" had one narrow definition (something like each printed currency unit is back by a specific amount of gold and that amount doesn't float), then yes, it would render it meaningless.

But if the amount of currency issued can float relative to the gold reserves held, then the values of currencies relative to each other could still flow significantly.

Put another way, it's an issue of trust. If currency X and currency Y are both theoretically backed by gold, but it's far easier or more reliable to convert X into gold than Y, then X as a reserve would be more valuable than Y.

> except that 3 does not fix as much as 6

On the logical flipside, 3 also doesn't alter nearly as much as 6. It was intended (and largely functions) as an iteration - not a backwards incompatible re-write.

It's not an irrelevant comparison, but I feel like it's an overstated one.
So he is saying that we need more expert system? I can't help but finding it a bit obvious.
The thing people who harp on debt miss is that it's a zero-sum game, not an absolute competition.

Yes, the US has debt, but if the market believes it's stronger than any of the alternatives... the US dollar still holds value.
I am a borderline narcoleptic. I can basically will myself to pass the narcolepsy test, and so I've had the diagnosis overturned. As a result of this, I have some experience with sleep studies and I received some information from doctors about sleep. This information should cause one to be a bit skeptical about the sort of "sleep hacks" that come up often on HN.

The test for narcolepsy I took consists for lying in bed the morning-after of the overnight part of the sleep test, and falling asleep 4 times. If you can fall asleep 4 times, and if you go too quickly into REM sleep every single time, then you are a narcoleptic. Narcoleptics can fall asleep very easily and tend to go very quickly into REM, but they do not go very easily into the deepest stage of sleep, which is the stage the brain uses to rid itself of certain materials. So narcoleptics have a bit of a problem. Often, we can get what many would call a "decent" span of sleep. However, we may only spend a couple of minutes in the deepest stage of sleep, where we might really want more.

I own a Zeo sleep monitor, and the data that I got out of it corroborated what the sleep studies indicated: I get only a fraction as much of the deepest stage of sleep, compared to the average for my age.

So here's the problem: These "sleep hacks" that allow you to enter into REM sleep very quickly for "power naps" may be harmful to you in the long term. You may well never enter the deepest levels of sleep that serves important physiological functions for your brain.

> I'm not against polygamy or polyandry

Pedantic, perhaps, but while its generally acceptable to use "polygamy" to mean "polygyny" when you aren't discussing "polyandry" (because virtually all real-world polygamy is polygyny), if you are explicitly discussing both forms, its should be "polygyny and polyandry", "polygamy" includes both.

> On the other hand, we've long had a tradition of traditional married couples where the man keeps a mistress on the side, usually in secret (though secrets don't tend to last very long).

Its really weird to call monogamous marriages "traditional" when comparing them to the polygynous marriages, since while the latter have fallen out of favor progressively in the last several centuries, they have quite a long tradition pretty much everywhere.

That said, its actually in many places a long tradition for kept mistresses, particularly of powerful men, to be fairly open.

There really isn't much information there (or at least I can't find it). I'm not attacking here, just giving my impression as a potential donor, albeit with some skepticism.

I was able to find information on the Ford-Mozilla Open Web Fellows program[1] and a list of events[2]. Funding for the first is obvious, for the second it seems like many of the events either aren't run by Mozilla, just recognized by them, or the funding isn't directly called out.

It would be great to see broken down what funding actually goes to. mozilla.org, as I said, seems to just be banking mostly on the Mozilla name (the phrase "Donate to Mozilla, the non-profit behind Firefox" doesn't exactly keep things clear). The donate page has no information on the subject, the Donate FAQ is a wiki page with no information on the subject.

As an example, the EFF has a great "Our Work" page[3], with a nice overview of a bunch of projects and big icons leading to really in-depth coverage of their work in each of six areas. The page also doubles as a nice portal into the subjects of interest themselves, if you want to know more.

Hello Xefer -

Could we talk about your project-"Wikipedia Radical Graph"? Thank you!
I have a few objections to the evidence presented.

Keeping in mind that I don't disagree with the statement. Test coverage is an objective metric, and test Effectiveness is a... what is it again? How many bugs you'll find with it? Obviously the two are separate concepts.

This is my first objection: The paper seems to say that Mutation Testing is test effectiveness, but Mutation testing is merely another metric. They cite other papers, but papers that attempt to demonstrate that this metric is correlated with test "effectiveness".

Metric against metric, is that meaningful?

She presents graphs of results that seem to demonstrate linear correlation between test suite size/test suite coverage/and mutation testing (called "effectiveness") This is addressed later, "isn't this what we would expect?" yah! And the explanation for why it's unexpected sailed fully over my head. (I admit it! I'm dumb.)

finally, many test suites are generated on the presumption of achieving code coverage, is this test valid without also having test suites that were made without that goal in mind? Could such a suite exist?

so summary of my objections

* is mutation testing a meaningful measure of effectiveness?

* can you measure one metric against another another, get a linear relationship, and conclude any meaningful differences?

* does the presence of code coverage as a target spoil the conclusion?

I'd love to hear input on this.
English seems more appropriate than French in some domains, but when it comes to social communication, I prefer French.

The lack of masculine/feminine, and the "you" that either represent one or multiple persons[1] makes communication, especially texting, more ambiguous than in French.

> For instance, in higher-order set theory a (very strong) form of the axiom of choice asserts that there is a function "epsilon : set -> set", such that "epsilon x \in x" for x not empty

Such higher-order statements are easily expressible in TLA+ as long as you specify the domain of the sets on which you operate, which you should always be able to do when specifying real programs, even higher-order programs. Here it is in TLA+:

∃ epsilon ∈ [SUBSET S → S] : ∀x ∈ SUBSET S : epsilon[x] ∈ x

You just need to specify S (or parameterize it).

> Saying "I'll just use ZFC" is exactly the same as a programmer exclaiming "I'll just use COBOL".

I don't think it's the same at all, considering that 99.9% of math is done with "just ZFC". I don't doubt that type theory may let us explore other logics, but as a practical way for specifying real programs today I fail to see a case in favor of dependent types. Sure, I believe dependent types may let you define all sorts of modal logic, but in practice, temporal logic has proven a good way to specify algorithms. So I think that a more suitable analogy would be, "Why confine your thinking to von-Neumann machines when you can use a meta-logic to specify programs for Quantum computers and other computational models". In that case, "I'll just use a von-Neumann machine" seems like a very reasonable choice for any work that isn't theoretical.

I think "assholes" might be people who personally care AND practice direct challenges, but do so in a way that shame and blame individuals. Calling out mistakes is fine, as long as you don't assign biased blame to the person making the mistake. Startups are already difficult endeavors without the added pressures of being directly on the hook for a mistake. Teams should accept the suffering from an individual's mistakes with the assumption mistakes will be made by team members. If a given team member makes too many mistakes, then perhaps a review is necessary, but otherwise, it's a team mistake which can be learned from and used to improve the team and product.

> No exactly the same, but it is becoming more common for women in the United States to have children to multiple different men in quick succession. Definitely a form of polygamy.

While sometimes people refer to "serial polygamy", and there are some contexts where its actually reasonable to view that as a kind of polygamy, here, where the focus is on formal, recognized marriage structures and whether men have the opportunity to enter into them, it isn't the kind of polygamy that is at issue, both:

(1) because its not a formal, recognized marriage structure, and
(2) because even if it were, it would be polyandrous, and the paper is comparing polygyny (not "polygamy" more generally) to monogamy, so this would be driving past monogamy on to the opposite side, if it were relevant at all.

I'd definitely say that the absence of coverage is a problem. My view is that coverage is necessary but not sufficient for good testing.

We talked a bit about classifying tests but didn't do it in the end because it's surprisingly hard to do. I do know of one paper that looked at different kinds of tests, called "The Effect of Code Coverage on Fault Detection under
Different Testing Profiles": http://goo.gl/nnxgwE. The authors found differences between tests for error cases vs. tests for normal operation and between functional tests vs. random tests. IIRC, they had undergrads do a term project that had to pass 1200 tests before the final submission, and the professors themselves wrote the tests, so categorization was a bit easier.
