I find this rather confusing. I have some chops, but I have nothing public in open source. I have always been employed to do what I do. Also, I am really not going to put something on github now... my time is really expensive (I'd have to apply for a budget internally of non-billable hours. It really is pretty expensive).

Are you telling us or the line cook? :)

Expecting at 36, I disagree with you. It's given us less time. There is no way to wait until you have managed away all the risks.

Under discussion.

"June 30, 2015 5:05 am Greece’s IMF payment: When is a default not a default?"

You'd be mad not to at least be seen to negotiate with Russia though, at least to make your own hand look stronger.

Who says sovereign bonds need to be risk free anyway?

Absolutely! Default, and we'll just charge more next time. Whatever. Move on.

The motivation for this extremely anti-default push has not been clearly enough laid out, methinks. Bonds, government or not, are an investment. You think I am 100% the stocks I bought in a Ukrainian egg farm will not go bust? Hell no. All who invested in Greek government bonds should have done their homework.

No, no, no, no. That is exactly how a C64 tape cassette worked. Loading, loading, loading.

I remember getting further than ever before in Midnight Resistance (which sounded less rapey to me at the time), and then waiting for the next level, loading, loading, loading...

He who works for free, never gets thanked, as a wizened truck driver once told me.

Your work and your input will not be respected without a consideration.

(I just ego-surfed my hn name. The twitter guy is somebody else.)

Isn't it? I haven't enjoyed somebody being disliking a comment of mine so much :). I've been reading these all day.

1. What the question is and why it is important.

2. Broadly, what area of mathematics was used - how did they go about solving it.

3. Do we have a concrete proof? For a general case?

4. Where are we now and what is next?

Four extra lines in a nice IMRaD format would have been a nice addition to start the discussion. It looks like the reader still has a lot of work to do.

In mobile? I've shut so many sites down in the last two weeks because I couldn't read on my iphone over the ad. It happens less to me in this period on android devices I notice.

Python is better for programming, R is better for statistics. A lot of data analysis packages require a bit of both, so I usually use a bit of both, and C++ underneath when something has to run faster.

To expand, R has every cool statistical model (outside finance) to hand. It's deadly buzz. It's finicky as hell to program in though. Classes are a bit crap. Brackets are all over the shop. Arrows? Really? Meh. Statistical models take ages to program and test, though, and the academic paper that was published last week has had the model as an R package for 6 months.

Python is a beautiful programming language, especially for anything involving transferring data from here to there and possibly back again. I particularly like it when working with a diverse team of context experts, who would think nothing of laying a faecal nugget in your code-base, to save the time it takes to drink a cup of coffee. It's a lot harder to write crap code in Python than in many other languages.

So, in our local technical landscape, R is used for prototyping, and is used in a slave fashion for running complex stats models. Python is used as the "Controller" of the program, and also for database type operations, web-scraping, calling QuantLib, ...

What does take a bath mean in this context? I keep hearing it.

Oh, but the funded think-tanks?

I think linkedin's groups solve it a bit better. The problem with circles is that the people in a given circle don't necessarily have me in a circle. I can really just group the input feed, not the output feed. It's more consumption than distribution focused.

That sounds neat. Have you got a reference to it handy?

When used with caution, perhaps. Separation from a god-belief coincided with the start of my depression, so prayer would be super-not-helpful.

Nah. Least squares is necessarily optimal under a normal distribution, but that does not imply that it does not work if the distribution is not normal. It might even be optimal for some other distributions, I just cannot remember, and I have to watch the frying pan.

Laplace and Gauss were in mad competition to find a general rule for the pattern of errors for measurements in astronomy. It's around 1800, and the medium of exchange is letters.

Laplace has recently shown that the integral of minus t squared, where t goes from minus to plus infinity has a definite answer.

Gauss starts a paper, basically says, let's just run with the arithmetic average, the usual mean, as the go-to best estimate, from a big series of measurements of a single thing, each of which has errors, because, yeah, why not.

Moments later the guy shows that squaring the errors makes it equivalent to that thing Laplace did, and we now have a general rule. His argument follows by supposing each repeated error due to a specific cause has an expected error of zero, with no particular rule of distribution, but that as the number of specific causes goes to infinity, the Law of large numbers applies (go Euler, fair play). Hence, wiggley wiggley, Laplace's thing.

Beautiful piece of work, and resting on Laplace and Euler too, two other heroic oddballs.

The best thing is the underlying explanation: Take a nearly-infinite number of different measurements of a thing, each measurement with its own pattern of rubbishness, and the average of those measurement will approach having this distribution. That bit is what makes it so broadly applicable.

A good argument, to be fair.

Hmmm. I think it has well evolved beyond being a medical term of any kind and is now just an expression for somebody who is being stupid. There is a big difference being somebody who is stupid (something I would never say someone is), and somebody who is being stupid, which most of us do at least once a day.

Do the 20-something-year-old MBAs know either? Gosh, no. But they can whip up a MECE and crunch some numbers in their heads which look totally plausible.

I think it provides some value, but I am not a huge fan. In my experience, the devil is in the details and the failures come during the implementation, and the management consultancies in the Marvin Bower tradition explicitly side-step implementation.

Feel free to expand those explanations... :)

How is Erlang these days? It is on my to do list (Kanban board) to check up on whether I need to check up on it.

And really just flesh-hacker in an engineering accent.

The guide to python (and I am currently training up a few folks in python) seems to be a guide for complete retards to learn python. It's woeful.
