> Shills are easy to detect, as they out of character with the typical tone and style of messages on a particular forum. They also tend to have egregious flaws in reasoning and use emotional and heated personal attacks against the person or topic in question.

So in other words, you're claiming that non-accordance with the groupthink of that particular forum implies that the poster is a shill.

Furthermore, you claim that using "proper" reasoning and unemotional informational content is evidence that the poster is likely not a shill, as if it's that hard to actually shill for something without resorting to crackpottery or emotional appeals.

I don't accept either premise, and nor should you.

> Also, as many of you here on Hacker News should know, marginally ethical marketing techniques are commonly used by tech and other companies, including bought articles and opinion pieces, astro turfing, sock puppets, guerrilla marketing, software to assist in targeting specific forums and message boards, vote brigading etc. See:

The fact that "Commonly-used" techniques exist implies absolutely nothing by itself about whether a given comment is from a shill, unless you're willing to believe that the base rate for shill/non-shill is significantly biased towards shills and sockpuppets on a normal basis.

For instance, Ebola is "common" in Liberia, but someone coming in with the symptoms of fever and headache are still at least as likely to have flu (or even Lassa fever) as they are to have Ebola.

Considering how expensive stealth coatings are to maintain on airplanes, I wonder if this makes sense. Airplanes generally have more options about when they are exposed to the elements than tanks as well. I also wonder how many ISIS or Taliban soldiers have radar or thermal support.

I suppose it's meant to be a show of readiness against Russia, but there's no reason Russia can't adopt the tactics of ISIS and co (you could argue it already has).

There are tools that let you draw on the screen, no matter what other applications are running. At least there are such tools for Linux, but I'd guess there also would be one for Windows. Heck, I'd guess there is such a tool as a browser bockmarklet. If not, tell me and I write you one (would support Chrome and Firefox and maybe, just maybe, IE11 (canvas+pointer-events:none)).

> The alternative is choosing not to participate.

That's wrong.

I'm not participating, but I know that other people are posting pictures of me and reporting my whereabouts on facebook.

I've read somewhere that at some point in East Germany, 30% of the population were informants for the secret police / intelligence agencies. Today, wherever Facebook has traction, it's more like 80%, and they report MORE data than those 30% did (But I wouldn't blame them, because, well, 99% of people "reported on" are also reporting on themselves).

And I'm sure that every competent intelligence agency already has a live copy of the facebook database, whether by NSL or by bugging. If they didn't, they wouldn't be competent.

That's an unrealistic PSA at this point in time. Too many people are invested in Microsoft products to just walk away. Instead, a constructive and helpful PSA would be "Don't open attachments unless you both expect them and know who sent them, and even then, probably don't open them."
> More generally, "don't open files in random proprietary formats from strangers".

Disclosure and licensing of the format doesn't actually prevent any of the security issues, so I'm not sure that "proprietary" is meaningful here.

"Don't use software whose security profile you aren't confident in to open files" might be a better rule -- but then you could drop the "to open files" part off without any loss of validity.

"which incorporates technology that makes it invisible to enemy thermal imaging"

I call bullshit on this one. The US M1 Abrams has a 1500HP gas turbine engine. To develop 1500HP means producing at least another 1500HP in waste heat, if not more like 3000-5000HP. Let's conservatively say it's 1500HP * 732W/HP ~= 1MW

How in the world do they think they're going to hide a 1-5MW power plant? From the second video: Peltier plates on the exterior.

That's great, but it doesn't do jack to the huge plume of exhaust jetting out the back. And since they've got some kind of fancy exhaust cooling system they've got to be sucking up and discharging MASSIVE amounts of air to dissipate several megawatts without increasing the air temperature too much.

Even then, it's not too hard to turn up the sensitivity on the thermal systems a bit so you can spot these things.

Science is that if you work out all major groups of muscles with maximum intensity you use up all of the stored ATP energy and trigger anaerobic energy delivery mechanism which builds up lactic acid [0].

Do this for all major muscle groups and you get significantly raised metabolism throughout the day as your body deals with replenishing ATP, cleaning up lactic acid, and repairing small amount muscle micro tears.

> "The SIM card is your phone number"

It used to be a useful statement, but the US (and many other countries) now have phone number portability, and other stuff. I've changed my SIM to _stay_ with the same number from a different carrier in the past, after porting.
That's an odd definition of "forever", there. NetBSD gained its rc.d system at the end of 2000, with the release of NetBSD 1.5. FreeBSD started porting work in 2001, and that carried on through 2002. FreeBSD 5.0 with rc.d was released in 2003. OpenBSD didn't get the rc.d system until version 4.9, released in 2011. Is just 3 years ago "forever" in World Wide Web time, now? If so, does that make the 11-year gap between NetBSD and OpenBSD "almost quadruple forever"? (-:

Quite the opposite, Lua is one of the leanest and most efficient dynamic language implementations out there. Its design is actually really clean, if you take the time to learn it.

This is how I trade currencies, usually a Yen pair on a 30min timeframe. It does work and money can be made, but it is a lot less profitable then they claim (on the Yen pairs I trade). Generally, a very outsized event can erase quite a lot of gains. Even smaller ones can make you give back a bit (such as NY ebola news or surprise BoJ news). Over time those commissions/fees add up. Still, over time I would bet they could be profitable on this strategy on some timeframe. Of course, just profitability is a very different claim than their own.

Only if you buy the high end models though (930, 1020 or 1520). The other ones have good camera's for their price range, but don't blow away the iphone (except in low light conditions). The iphone does have one big advantage and that is the shutter speed. Lumia phones take a while to take a picture, whereas iphone does it instantly. For action shots, the iphone is a better camera.
It's unfortunate IMO that Lua didn't just adopt BitOp and its semantics. The different decisions made by the core Lua developers did not seem compelling to me.

For example, one of the differences is that you can shift by a negative number with Lua (making the shift go in the opposite direction). Who ever needs to do that?

This was all discussed at length on the lists, I don't have a link handy though.
Ask HN: How are markets initially bootstrapped given initial lack of liquidity?
I'm quite curious about is the process of bootstrapping an exchange like btc-e.com or vircurex.com. I know a little about market microstructure and orderbook dynamics seems really interesting from the perspective of having an efficient, scalable data structure that can accomodate an arbitrary number of added buys/sells and realtime modifications in a highly concurrent setting.
I think I understand the overall mechanics of an orderbook, but it seems like you would immediately (upon initial deploying or even during dev/testing) face the problem of "OK I will make the first trade of this new exchange" and submit a SELL order for 1 BTC for $351.5 (example figures), whereby nothing happens because you don't have any liquidity whatsoever... That is the first thing I am wondering about. Does every exchange just implement their own orderbook? I read this post that explained a good way to design an orderbook (http://www.quantcup.org/home/howtohft_howtobuildafastlimitorderbook) and it was useful in understanding how they work, but in the real world context of building a working application, I'm experiencing a disconnect in how to realistically get users that would be willing to use it early on when it's just running on testnet.
On a very superficial level this appears similar to the issue of any application that is dependent on a bidirectional relationship (Amazon has buyers and sellers, Airbnb has hosts and guests) but the unique aspect of an exchange web application is the fact that the orderbook concept doesn't really equivalently exist in other marketplace structures so the process of bootstrapping must be significantly different than what you'd do for a dating website (example).
I am looking for some input and just general thoughts about how the process of building out an exchange would entail with regard to making it a liquid market with a deep orderbook from as early on as possible.
Thank you in advance, I look forward to and would appreciate any feedback.
89% over 2 months. Not bad. My algorithm did 8,000% over 6 months using real money on real exchanges and I have the trade history to back it up.
That's why SMAC worked so much better in the far future (22nd century) without the burden of explicitly extrapolating current geopolitics and going all in on agenda/ideology driven factions. The current faction/sponsor selection looks way more nationality based and just seems to cater too much to the respective major digital game markets of today: US, Western Europe, Brazil, Australia, Eastern Europe, plus the token African Union, while all of Asia get's lumped in into one minus the Indian sub-continent. This just all feels like Oprah Winfrey driven game development («You, get a faction, you get a faction, everybody gets a faction»).
Maybe I just miss those cut scenes and quotes, they really set the tone in SMAC; Beyond Earth so far, is sadly enough an OK game, yet forgettable.

"In essence you are saying that you don't agree with Assange so his name should be smeared to keep his opinions from reaching the public."

Nope. And even if I did think smearing people was okay, there's no need for dishonest characterizations when the man is openly making a fool of himself. If honest discussion about what he's actually doing makes him look bad then the fault lies with him, and not the people who are simply noticing that he's losing the thread.

"You are claiming that you are able to parse and analyze his statements for their truthfulness, whereas the rest of the public will be hoodwinked"

Oh really? Do say where.

"Arguments should stand or fall based on merit,"

Well, at least you're right about one thing. And speaking of arguments falling on merit, yours begins by distorting something I said to assert something I neither said nor even implied, then departs even further from reality by asserting I'm "claiming" something about my own abilities in relation to those of "the rest of the public" even though I made precisely zero mention of either. Seriously, at this point you're just making shit up. So of all the faults in your position, I'd say basic dishonesty tops the list. And that's a bit rich coming from a guy who started by railing against "smears."

I see no mention of the spread, costs or even ability to put on a short position, exchange lag variability (huge issue when simulating even on modern exchanges, let alone fly-by-night bitcoin markets). Additionally, it is very easy to find trend-following signals that "work" but break down when conditions change very quickly. That seems to make up most of the prediction, along with an order book imbalance signal that might be more stable.

I think a better approach would be looking at order book features and lags vs. other markets. The costs are high on BTC markets so it would be pretty tough to overcome those though. Anyone with experience to do this is probably doing it somewhere more lucrative. I think BTC markets only trade a few million USD a day.
I some what agree on that. I don't subscribe to Mr. Greer's overly optimistic perspectives on aliens, to say nothing of his meditation group meetings and incessant and obnoxious name dropping in nearly all his speeches.

If you ask Mathematica whether x^n + y^n = z^n has solutions for n>2 and x,y,z>0, the system will simplify it to "False", displaying knowledge of Fermat's last theorem. This is taken from documentation (last example in http://reference.wolfram.com/language/ref/FullSimplify.html).

I asked about x^n + 1 = z^n, which is a simpler special case with y=1. The system no longer recognized it to be False. So the theorem was programmed as thoughtless pattern matching. I think one day computers might become authentic "creative" tools for mathematicians (as opposed to "computational" tools), but Mathematica's philosophy seems to be a dead end in this regard.
