haliax··on A free, complete guide to Technical Analysis
Actually, I don't believe this is correct. The weak form EMH claims that any information provided by the price history of a security should already be incorporated into the current price. You can claim that Technical Analysis (construed as patterns in charts and the like) isn't valid and that weak form EMH doesn't hold, if you believe that charting fails to correctly incorporate the relevant information from the price history.
haliax··on Exploding Offers Suck
How would you advise someone to learn how to negotiate and get better at negotiation?
haliax··on Anti-ageing compound set for human trials after turning clock back for mice
> But anti-intellectualism is not cool. Saying "she did a little dance and that's all there is to it" or even "she's just being young" is more obnoxious than the fact that she did it.

It isn't anti-intellectual to question the validity of any analysis. Your argument, taken to its conclusion, provides as much protection for the previously mentioned analysis of Miley Cyrus's dance being a grounded argument to make, as it does for my claim that she was subconsciously invoking the goddess Kali.

I'm a coder with a strong synthetic bio interest. (I've done some stuff at GenSpace in NYC. Email: devan.lochees@gmail.com -- please get in touch!
haliax··on Tell HN: How we bootstrapped to the #1 rated mattress on Amazon.com
Literary knowledge has little to do with measuring people's enjoyment of a book.

Mattress quality has a great deal to do with measuring their enjoyment of a mattress.

haliax··on Satoshi Nakamoto is probably Nick Szabo?
I'm guessing this has something to do with your username, so what is the better unix? BSD? Minix?
haliax··on Don't trust me: I might be a spook
You're using a very specific definition of backdoor there. I can think of others that at least seem plausible to introduce at the compiler level.

Timing attacks for instance, could plausibly fall out of optimizations that terminate a loop when it's clear that the value being computed won't change (e.g. is false and is repeatedly getting anded with things). This would probably be even worse for power consumption or other side channels. For a potentially easier to measure side channel, you might try introducing some state-dependent delay (short and caused by something like that loop optimization) in a bit of code preceding a packet send.

Alternately, introducing (via incorrect optimizations) the right kinds of buffer overruns or race conditions that corrupt a pointer just right, could get you a nice stack smashing exploit with certain (very abnormal) inputs -- and remote access to the machine in question.

haliax··on The 1975 Buffett memo that saved the Washington Post's pension
> For 100 stock fund managers buying and selling stocks, statistics tells us that 50 of them will do better than the market averages (and 50 will do worse).

50 will do better/worse than the MEDIAN of that GROUP OF 100 fund managers, not the market averages.

haliax··on No, really—consciousness is worth thinking about
Why should it matter whether or not "qualitative experience is fundamentally no different to the state of a Turing machine"? I don't see a claim anywhere that a Turing machine can't be conscious.

"but it must exist because my subjective perception tells me it does." seems like a rhetorical trick, consciousness is the underlying mechanism of perception, so it's not my perception of it that tells me it exists, it's the fact that I have perception at all.

As for a null hypothesis, how about this: "If my qualitative experience is no different to the state of a Turing machine, it should be possible to temporarily modify my mental state to remove all qualia -- so that I perceive nothing, but am still able to process everything" (In short, if I'm running code like sensoryData.processWithFeedbackTo(consciousness.Perception), it should be possible to do sensoryData.processWithFeedbackTo(null) temporarily)

haliax··on Obama to release FISA court opinion that ruled NSA surveillance unconstitutional
I have to take issue with the point about negative statements, surely it's no more fruitful to say "Prove there IS an invisible ball of undetectable mass swirling in my hand."

Wouldn't it be more accurate to say that it's fruitless to place the burden of proof on a statement which is syllogistically isolated from any statement known to be true?

haliax··on Keep Mozilla from hijacking the Internet
Upvoted to draw attention to this dishonest piece of astroturfing.
haliax··on The theory of relativity in words of four letters or less
This is phenomenal, does anyone have sources of more physics concepts explained simply?

Scott Aaronson's Quantum Physics is one: http://www.scottaaronson.com/democritus/lec9.html

haliax··on Food Practices Banned in Europe But Allowed in the US
Is there a good way to buy only products that avoid use of these chemicals?
haliax··on NASA has three smartphones orbiting the earth as mini-satellites
What sort of analysis was used to figure out the power and protection requirements you needed to make these viable?

Are these within reach of an individual to build, if not to launch?

If I build one, how do I launch it?

Why do the signals need to be crowdsourced over Ham?

What are your personal favorite/most cool applications for lots of cheap satellites?

Seems like a promising approach. Does anyone know about this?

If you could build a sufficiently cheap robot capable of navigating rough terrain would that do the trick?
haliax··on Robot Dragonfly
Typically, you'll have something like the following: - The government funds the research - The developers get first refusal on patenting - If they refuse, the government can patent - If they patent, the government is given a perpetual free license to use the technology
haliax··on Oil Espionage: Traders Spy on Hub With Satellites, Sensors and Infrared Cameras
That sounds really interesting. How hard do you think it would be to automate that kind of analysis of newspapers and such? Would love to hear what you think. Email's in my profile.
haliax··on LOOM 4k short film by Ridley Scott & son goes online
There's no reason you can't innovate within representational art, and your "freed itself from almost every constraint imaginable" is someone else's "descended into idiotic gibberish".
haliax··on Show HN: Music for Geeks and Nerds
I think that that's what the chapter on primitives -- introducing csound is for. Also, I think that experimenting with musical conventions and the like is really interesting. If you want to talk about this sort of thing further, my email's in my profile.

haliax··on With Kickstarter, Who Needs the National Endowment for the Arts?
It's possible that the art in question is ahead of its time, or expresses radically unpopular ideas.

I'm not saying that a piece of art that no one ever cares about after it's created is valuable, but it's hard to judge the value of art based on current popularity. Plus, the judgement of popularity is influenced by the culture at a given time, and the existence of a given work or works might have a pretty big impact on the course of that culture's evolution -- regardless of its initial ability to gain funding.

There are also the practical difficulties of making sure that the funding request gets in front of the people who'd appreciate the work in question, and that they have the money to be able to afford to donate, and that they're not disinclined from donating for reasons that have nothing to do with the artwork in question (e.g. they think kickstarter is some phishing site, or think there's no point since they can only give a very little bit).

haliax··on Ask HN: Python as a Trading Platform
I get data from Y! finance, using urllib2, and then use csv.DictParser to get the daily price series. From there I write code that takes in those series for a given basket, and buys/sells and keeps track of P&L, then use matplotlib to view results. Email's in my profile if you want to talk more.

Can you go into more detail on your setup? I've been using Python to simulate interday ETF strategies -- which is a relatively simple matter, but haven't really done anything to complex with it yet.
