I mean for the problem at hand ... not for anything, ever :) I think usually the argument for Spark and the like proceeds by just making the dataset bigger until whatever you’re comparing becomes absurd (e.g. command line vs Spark). It was

This is cool and all, but one could smash this out with gnu parallel and awk with no problem. Almost everything mentioned can be done on a stream including the aggregates with non of the Spark fanfare. You could also happily do this with Pi

I'm surprised that at the time of writing the word "portfolio" didn't seem to feature at all on this page. Why not curate the things that you've done on a portfolio page which you can use to evidence the extent of y

I think your statement sounds controversial but I’d be willing to argue that. I.e the opposite of formal is indeed intuitive. I’d start like this : if you’re explaining something in English then you’re invoking and reliant on the readers co

My point is formal language doesn’t mean “doesn’t require intuition”. By “intuition” I mean the appeal to something you expect the reader to believe without further proof. I hadn’t seen the Wikipedia article you point out but Peterson graph

Sure. Prove that a Peterson graph can’t have a Hamiltonian cycle. Often given as a paragraph of English. Actually I’ve only seen it that way personally. Of course you could (in this example) prove it deductively since Peterson graphs have a

This is also well studied in Philosophy. Even not that hard math proofs call on intuition pretty quickly, and I think it’s a legit question to ask when does it basically become empirical proof. To my understanding maths has a common basis i

I think the tldr here is that questions/challenges require significantly less energy than answers for many types of questions; and this is more true the more expertise the answers require. I think one problem is that expertise have bee

I think that you make some excellent points. I think we need to stop conflating maths and abstraction with genius and general intelligence: it's too important to be politicised. I also think we should assume that any healthy adult can

Octave is just great if you do a spot of computational maths for a living and need to smash stuff out quickly. It’s interactive, really well suited for matrix operations, has all the packages you’d expect for analysis, optimisation, etc. Li

This feels a bit overly specialised, and the average article is hard. I’m sure a maths researcher can handle it and all but it does seem rather taxing. I think for something like HN to be broadly interesting it needs volume and variety, bec

by usgroup 8y ago
Indeed. Besides, and anecdotally, I think it’s moreso give-a-f%%k that decreases rather than intelligence.... Anything that purports to measure “intelligence” will be confounded by give-a-f%%k. You can’t separate the two.

IQ tests are illegal: https://en.m.wikipedia.org/wiki/Griggs_v._Duke_Power_Co . I see the parallel you’re drawing but in this instance it’s important not to. IQ is divisive precisely by being made synonymous to performa

by usgroup 8y ago
I think that it’s illegal in the US if it is specifically an IQ test. Otherwise, if it’s basically an IQ test but not called an IQ test then it’s not illegal. Eg a logic type test or a mental maths test. IQ is very interesting on the first

Tbh I imagine their edge is more likely to be better data and a secret theory. Then the applied part of it is simple but different: different analysis, different theory, different data, extraordinary results. Edit: just read your article ..

by usgroup 8y ago
Remember reading an article by an ex rentech guy who says that linear regression is about as complex as the modelling gets; that the edge is not in making things hard.

I think at least caveating your advise with “learn as much applied maths as possible” may be an improvement . From there, “learn as much relevant applied maths as possible” would be more time efficient. And from there, “learn financial ma

As a textbook, I suggest Investment Science by Leunberger. It's concise and has great coverage, and you can just keep referencing it over time. As an initial focus, I suggest understanding discrete time models well. If you've got

Defs agree. I run my own business and work with other business all the time. The secret sauce formula is rarely heavily weighted towards general intelligence. All the dumb things will kill your business way before you have to be the smartes

Game theory itself has been applied to trading ad Infinitum . Indeed short squeezes, liquidity traps, algos that hunt algos, are all a common feature and motivated by a study of the competition. I’d venture to say that trading might just be

This is full of gems ; and a great compendium I wish I had 10 years ago. However, honest advise: if you actually really want to trade in this way, start with a solid course in mathematical finance. It’ll teach you how to model the space, th

Sure but we were talking about precision rather than throughput ; tbh the result is hardly surprising .

by usgroup 8y ago
I think you’re wrong about the ML precision. You need highly precise for most recursive machine learning tasks because you’re compounding errors otherwise. Typically you can’t even use floating point representation: not accurate enough.

Maybe I’m just simple but couldn’t you say it was always case that the human hive mind is a bit like a giant analog computer ? Not sure why the digital stuff is important for the analogy.

This looks like responsible disclosure of a partial breach to me. It’s required under the GDPR for example and the company likely already reported it to the information commissioners office of its equivalent. If you buy that this can happen
