Why would an archaeologist be more qualified to guess how they built the pyramids than an engineer who studied the pyramids for years?

Or are you saying we should just dismiss all of the content because you don't like the organization that published it?

I question your belief that you can evaluate information based on the organization that provides it. Or at least that some popular or well-respected organization can be trusted to provide good information. In fact, oftentimes the most widely trusted organizations have the most invested in maintaining the status quo, which makes facts subservient to that core need to sustain the venerable order of things.
The pyramids were actually not built by slaves. There's quite a bit of evidence that would suggest this.
I see so many random terrain generation posts, like it's some sort of a hard problem that's being solved on a weekly basis. This one isn't even impressive.
Were they slaves? I've often seen reference that they were citizens working on the pyramid as payment of taxes in the form of manual labour, add to that your boss and the building were being built for, who to them was, a God.

I'd say whatever the most simple explanation is the answer I could see either rubble or ramps.
There was one down the road from me until just last year:

I don't think it had been used for years, but it was a notable part of the Gloucester landscape.
The slope of the lines indicates how big an impact different incomes have. Contrast India and Nigeria, for example. A Nigerian needs a lot more to have the same incremental in increase in satisfaction as an Indian.
Interestingly, Germany, Russia and India seem to be about parallel, even though the income ranges are different. Is that just coincidence? Or is there an underlying cause?
Also, how well does the question itself translate among different languages and societies? Can the same concept be put across effectively?
Not to be too US centric, but the time standard should be set around New York City. Bankers in London and San Fran all work on NYC time.
Historically speaking, Lisp was the de-facto language of AI for quite a bit of time. That's only been the case for classical AI research, however. People working on AI and machine learning these days aren't necessarily all working in Lisp -- they're usually working in high-performance languages, or in interpreted languages with high-performance libraries (e.g. Python plus numpy or scipy or what have you).

This is exactly the sort of problem that convinced me that consciousness/mind must be a fundamental part of the (multi/uni)verse, and not something that "emerges" from matter.

I find it terribly unconvincing that a specific arrangement of matter, or even an algorithm in software, just simply "spawns" a discrete consciousness from nothing. It might make sense if there was an underlying "consciousness field" or some such concept that the matter-arrangement tapped into in some manner.
Sure, you would have to know that. But you have to look up if the business you want to contact is open on Sunday anyway, even if they are local. Or what time they close today.

Or you have to try to figure out the whole no work on Friday thing in the middle east and Monday being part of the weekend.
You always have to look it up.

What made this dream cool in the digital age is I could just have hours that I'm available and if I wanted to work late at night, I could. I considered myself a 'hardcore hacker' in '98 and what appealed was how well this lined up with my natural inclination to hack on code from 10pm to 5am every day, despite being in high school.

I didn't care or need to know where my IRC friends were. We could collaborate none the less.
Interesting logical fallacy they're employing: by inverting the inequality such that the upside is capped, they're strongly implying that the value is non-zero. This shifts the conversation away from the value being, in fact, zero.

At most 1 person may have been killed by the official making that statement.

At most 1 child may have been abducted by journalists mentioning Snowden's name.

Nice trick. Wonder if it'll catch on with other officials?
I would personally choose not to over complicate things and simply make this the app "for when you absolutely, positively, have to be there." If there's a possibility of cancellation, well—you're looking for another app, then. I realize this will decrease the number of times the app is used, but I'd say complicating it would be worse.
Beyond the usual security/freedom dichotomy we can go on for ages about, there's also a question about effectiveness.

We tell ourselves that having security cameras will deter criminals, because we say "well, it won't entice them will it? ". But there are two points about this:

- How effective is this? If installing cameras all over the city of London stopped one person from being mugged, is it worth it?

The big issue with trying to measure this is two-fold. Firstly, the notion of "stopped" is a bit hard to measure. Obviously, the number of people caught thanks to evidence on the cameras counts, but if there were eyewitnesses as well, does it still count? Inversely, what about the chilling effect brought on by the cameras? How do you count the number of people who don't even think about mugging thanks to the cameras? And who's to say that the crime isn't simply displaced? Society is pretty bad at figuring out general supply demand curves (an example: We would think that raising wages would entice people to work more, but a decent amount of arguments exist to say that after a certain wage level, increasing the wage would decrease the number of hours we work (substitution effect with leisure) (http://en.wikipedia.org/wiki/Backward_bending_supply_curve_o...)

-How do we measure effectiveness? I get mugged and lose a $200 phone. I think I would be slightly irked by it, and quantifying this as merely a $200 loss might insult me (especially considering I'm not very used to being mugged and I would consider it a traumatic experience).

A terrorist attack has a similar quantification problem, there are widespread psychological effects (even just the loss of loved ones, beyond the macro "security theater" stuff which induces circular reasoning). And the economic damage can be longterm.
jacko0 and ksrm [EDIT: and icecreampain], you seem to be under some kind of ban - what you write appears gray, and is invisible when I log out - despite them appearing to be perfectly valid contributions.

I really hate this whole banning on HN - the fact that people get banned and continue posting without knowing it (sometimes for months) - seems to me like the elementary school bullying technique of putting a post-it on someone's back and letting them walk around with it.

Because routing is the bottleneck.
nice but sadly no AI and no other players :(
Mostly because... I have no idea why. I mean we've discovered something very close to spears being used by people since ... well forever in terms of modern history.

And hunting being very important to the needs of certain homo sapiens sapiens populations would very much agree with your assessment. One advantage that we hold over primates is our ability to throw. Combine that with making spears and our ancestors quickly becoming apex predators makes sense.
When people say Bitcoin is a money standard for the internet, it reminds me of this. A time standard for the internet, similar to UTC but human-friendly.

A few things worked against its adoption.

First, it was too proprietary. A modern initiative based on open standards would have a much better chance of gaining a foothold in niche communities, much like Bitcoin.

Second, it was before its time (no pun intended). The web was already popular, but not very real-time. There was some chat, but it was pretty geeky, not like Skype or Facebook IM now. And hardly any videoconferencing or live-streaming. And not as much distance working as happens now. So there wasn't that much demand for syncing time.

Third, digital phones were locked down by the manufacturers and carriers (watches too). It would be hard for a grassroots movement to grow if no-one could make apps supporting the new time standard.
Go to Twitter settings and remove the access for that app. Bypassed. Uninstall or flight mode might be another idea.

Seriously, all those todo/productivity/alarm apps that try control you are just bullshit. At least as a techie you could circumvent them all. In the end, it's all about your habit and your will and going to bed earlier etc. and the use of that app is, if any, only some creative reminder. It's important to get that the app itself doesn't solve anything for you.

Also note that if there is any unjustified punishment (in this case e.g. a huge traffic jam, canceled trains, ...) or just misbehavior of the app or the hardware itself (e.g. no location data) the effect might be rather counter-productive.

Probably by the php extension in c :) I would think that phalcon router will be faster too.
this is buggy on my computer. only white moves and white moves everywhere, killing stones like in chess, no matter which color.
How feasible is it to even float massive stone blocks by attaching animal skin balloons to them as is done in the video? I would have figured that you would need many more than are shown. Also, how would you protect the balloons from pushing out of their restraints as they rub against the upper diagonal wall of the near-vertical channels?
Yes. I thought the same exact thing. Also, I was wondering exactly how the water was magically moved around a the top of the pyramid? I can see evacuating sections, but then you would have to wait for the next rains to refill them. That would take an incredibly long time. Imagine how much work would be required to bring more water to the top of that pyramid to refill the sections AND the leaking flotation columns. Heck, imagine the PSI of water at the bottom of the pyramid columns when they were reaching a hundred feet high?
There appears to be a single main diagonal that includes China, Russia, Italy, France, and Germany.

Above that diagonal are countries where it takes less money to achieve that same satisfaction as those on the main diagonal. Apparently, Brazil, Mexico, India, and Nigeria get more satisfaction for the same level of income. That leaves Japan and Iran as the outliers where you get far less satisfaction for a given income level.

The slope of the lines is also interesting. Nigeria and Brazil stand-out as two places where income matters less it does others. The US and UK are also flatter (less income elastic) than the main diagonal.
Honest question: how do hipsters behave? Wthey have appeared in mass just the last year here in Spain(just very unusual before ). So I've had no oportunity to interact with them (just with some friends that are in a rock group, they have to keep an "attitude", but I think is mostly to keep the artist behaviour that people expect)
Greenwich wasn't arbitrary at all.

I pray to god if he gives the speech, it is filmed and made public.
Density of limestone is about 2.5, so the volume of floats would be about 2.5 times the blocks.
I like that. It seems that git-flow is a good match for weekly/monthly releases and github-flow is a good match for daily/multiple times a day releases.

As far as I can tell the only real difference is the existence of a develop branch in git-flow that allows integration testing before a batch release.
This seems like a great channel for spammers, but I suppose Apple/Google would permanently ban the user's account quickly.

In a mass used platform a single user should never be able to receive 100% visibility by a simple action.
My favorite theory is that the blocks where cast in place.

The part where they float the blocks up the side seems dubious to me.
That speech was awesome and if I was the RSA, I would be reconsidering asking him, considering what he could say.
Auditing != code review. Static analysis and fuzzing count as auditing in general (and fuzzing works on closed source too).

@cromwellian's citation of Snowden on weak endpoint (OS, PCs running Windows especially) security is on target. Security is never done, and there are too many levels and spots to attack for users, open source projects, and even big companies to be able to afford defense everywhere. (Get a load of https://www.openssl.org/news/secadv_hack.txt if you haven't seen it.)

The browser cannot be excluded from this analysis. It presents a large attack surface, and top browsers have wide unverified binary distribution nets.

Adding exploits to Linux open source has been attempted but detected. We don't of course know of undetected successful attempts.

The risk of coercing a browser vendor is hard to quantify. Ladar Levison of Lavabit was brave enough to speak up pre-gag-order and shut down his business.

Have the principals of other companies been that tough? We don't know in some cases, but in others the answer is "no".

Even excluding what some such company principals didn't know but should have known (oops, unencrypted data over telco dark fiber), the bigs knew enough pre-Snowden to make a public stink. None did; many (AT&T, e.g. -- there are other examples) were complicit for decades.
Self-publishing has been around for more or less as long as there has been books.

Personally, I hope it doesn't become 'mainstream' otherwise every Tom, Dick and Harry who thinks they can write will be churning out their own 'masterpiece', and then wondering why no-one is interested in it. There is something to be said for budding authors to get their 10,000 hours in in 'publishing silence', and then produce something actually worthwhile reading.

That said, if someone has produced a guide that will benefit good writers that otherwise might flounder a bit with the self-publication process, more power to them. And the creator of this approach does note, to his credit, that this won't make you a better writer. I wonder how many will take serious note of this point!
Dates would be the same day forever. Financial quarters would be even and easily divided. Never print a new calendar. Etc.
I was a 14 year old who attended the initial launch at MIT. I remember at the time thinking: why have a random synthetic time, perhaps we can just accept GMT as internet time.

I still don't understand why you'd have Beil Mean Time - perhaps I haven't grown.
I think computer programming can be a much more accessible way to learn problem solving and general thinking skills than other fields. Computers don't need to cost a lot of money these days. So one computer can provide a lab with infinite interactive experiments. Programming gives more feedback than mathematics.
It's interesting to see implementations of algorithms in languages. Terrain generations is a fun problem with a few algorithms and nice visible results.

Maybe you should consider showing some stuff that you've made instead of being snarky about stuff that other people have made and shown.
Question is: why would he be speaking at RSA conference.

Imagine him speaking at PyCon closing. Why would he go there? It just makes the conference more like high school / college graduation where you invite someone interesting/outstanding to talk about what it means to be successful person. Do we need someone else to tell us how terrible X is doing? What public policy is bad? How to become a successful person in the industry? I mean come on... I reserve my conservatism here. If someone else needs to mock RSA / Python / Ruby whatnot, let someone else in the tech community do it?

Greg says he wrote his first LISP interpreter in FORTRAN, around the early 1970's. I was thinking that NEST might have code that emulates certain properties of LISP, I've heard of many LISP interpreters being written in other languages over the ages.
The reason why people can't do that calculation in their heads is because of our reliance on computers and calculators.

In fact you can pull up articles with a quick search about how people can attain pretty good mental math capabilities through training. It's hard work, but it's proof of the adaptability of the human mind.

I don't know I already thought the computer was the first "lever" for the mind that we've had. The computer has been pretty game changing for society, has it not?

I'm a little skeptical of the conclusions drawn from these questions, especially when they're phrased in terms of surveillance data directly preventing specific attacks. From experience elsewhere it seems (I claim no expertise here) that you rarely begin looking a terrorist's or potential terrorist's communications at just the right time (neither too early nor too late) to discover a planned terrorist attack for the first time. What happens more often, apparently, is that you start looking at someone's communications and you gather information useful to turning them or someone else into an informer. Then you discover attack plans drawn up in the future because your double agent calls you up and tells you about them directly.

If the US is in fact using domestic surveillance effectively to generate informers, and thus prevent terror attacks, then US alphabet-soup spokesmen might plausibly be very slow to mention much about it in response to questions asked about specific attacks being directly detected through surveillance, both because a) the question as phrased doesn't cover such operations and b) you want at almost any cost to say nothing about them. Though on the other hand, if you aren't having success in those operations you wouldn't feel like saying much about it anyway, partly because it means you're failing at counter-terrorism ...
That sounds like a great option for in app purchases.

Jan 1 is a entirely arbitrary demarcation that's not actually terribly useful to the way we actually experience time and the year. IMO a better place would be one of the solstices or equinoxes (I'm partial to the spring equinox).

Also breaking the year into quarters, from equinox to solstice would be a better match for to scale we live an think on. Also it's just the right amount of time for a good portion of a large one-man project.
The MSP430 has a constant generator register, which depending on the access mode used will generate offsets and zero. I'm sure there are a few others.
He made this film so people could travel to the city of London without being there. I bet he did not expect it would be used by people 100 years in the future to travel back in time.
I agree with you cosmically, but January first has real meaning for me because its the start of a new tax year.

(I have no idea what I'm doing...) how much does 1 cu-foot of water weigh compared to 1 cu-foot of limestone? water is about 63Lbs / cu-foot. limestone is 163 Lb / cu-foot. So, 1cuf stone in water is 163-63=100Lb (it's already partially buoyant because it's IN water). Then you need to evacuate water using air bags that are ABOUT 1.5 times the blocks size. So, the whole payload would be 1 unit block with 1.5 units of air. or 2.5 units total. Much bigger than the video suggested. But not unreasonable.
You presume every shop in the town/city will accept this BitCoin plan. If not, then punters will just switch to the shop that operates with dollars, and accepts the risks/drawbacks the shops in this article do, and you're business will fail.
And I can't seem the find features of C# in Python.

Which features of C# are you looking for in Python that you can't find?

Also, keep in mind that something that is written in good, idiomatic C# might need to use different idioms in Python in order to make sense as a Python program (and vice versa).
If you're a C# programmer and you want to stay one, then stay one. There are many startups out there that would love to have a skilled C# programmer, I'm sure.

It might depend on where you're living, I'm not sure.

Also, afaik C# is open source, check out Mono. (somebody correct me if wrong)
Thumb-2 immediate encoding is even more gleeful--in addition to allowing rotation, it also allows for spaced repetition of any 8-bit pattern (common in low level hack patterns, like from [1]) to be encoded in single instructions.

Maybe I'm missing something, but I don't see either this or the original even remotely as a difficult question.

Making 80% of the median income is completely within normal ranges; it seems to me it would be barely noticeable in both cases. On the other hand, the difference between US$100,000 and US$800,000 is gigantic, it's a complete change in lifestyle and security.

Seriously, does anyone here actually find either question to pose a true dilemma?

People become acclimatised to 'new wealth'. One thing I learned from life experience, and then actually understood after studying Buddhist philosophy, is that it's very easy to enter a repetitive cycle of desire, some achievement, then more desire ... one yearns to make more money, makes it (via payrise or other successful project), gets used to having that money, wants more, makes more, and so on. The trick is to be satisfied / happy with what you have; it's not practical or very likely that your income will keep increasing 'forever'.

I can honestly state that I'm happier now making less money, not owning a house, nor having many of the trappings of 'success' that I had 10 years ago. I admit, however, some ill-placed desire to see if I might be happier now 'making money' than I was in the past; my healthier (IMO) life outlook might be simply as a result of more wisdom rather than less money.
