As to smell, that was a stupid way to do it.

We can detect levels of lots of different things. Instead of 1 or 0 over time it would have made a lot more sense to say Ok, I need to be able to encode 140 characters with 37 choices (alpha-numeric + Space).

There is a humidity sensor, a Carbon monoxide sensor, an oxygen sensor, and a Carbon dioxide sensor. All are really cheap.

If you a tube and 37 levels that you release water, carbon monoxide, oxygen, and carbon dioxide to. You now have the ability to send. 4 characters at a time. Since alcohol sensors are cheap, we can use that for "parity" so we know that the message was sent correctly.
No, the Express genuinely is that crazy, you could create the same panel of images for conspiracies about Princess Diana being murdered. But, other than the Mail, it's not at all representative of the rest of the British press.
because the electricity company will still need the full capacity of the grid in power plants spinning idle to be able to react to renewble output changes. So not much savings on existing infrastructure.

That combines with selling 50-60% less in the limited deployment case, 90-95% less.

That means prices will need to increase by a factor 3 in the limited deployment case, factor 10-20 in the green's "dream scenario" case.

The gov't asked for specific access to specific account(s), those were not complied with, so they requested that the ssl certs be handed over so that they could get access to the specific individuals they needed. None of this is illegal.
Distributed power generation can never match the efficiency of centralized, for obvious reasons.

This may not matter for renewables, as there's no fuel burned ... but ... I doubt it will turn out that way. So a larger cost will be much more efficiently distributed amongst it's users.
My tutorial for setting up fish on Mac OS X and Ubuntu: http://hackercodex.com/guide/install-fish-shell-mac-ubuntu/

I've never had any trouble using chsh to make fish the default shell. Bash scripts in crontabs still run under bash -- not sure why anyone would think otherwise. Plus, changing the shell command for iTerm/Terminal won't help with remote servers, so using chsh everywhere means you always get a consistent shell experience, no matter whether you're using your terminal locally or remotely.

ltrace is also pretty neat; it shows library calls (as opposed to system calls) - so you should be able to see the missing "strcmp()"s alluded to in the article.
Eh, that doesn't contradict the official death toll. Did you even read it. It reckons that some people think there might be thousands by 2065... which is a little silly, since there would be thousands dead by then anyway and there is no way to link the deaths to the disaster.

The problem with describing that as a problem is that there's no mandated way to operate a business (other than lawfully)

Levison didn't design it to make it harder for the govt specifically, he designed it that way to make it stronger for his users as against the rest of the world and would then make exceptions for the govt (which they turned down when he offered to custom-tailor a solution)

Bullshit. Would you also argue that it's okay to ask how many white men work there if you were a white man? If it is a job where things like race, gender, age etc have no effect on the work itself, any of those questions are completely inappropriate regardless of who is asking.

I can't claim to know anything about naval nuclear engineering. My intuition tells me that avoiding runaway criticality and avoiding crew contamination are high priorities. Based on this I can think of 4 significant questions off the top of my head:

1. How might they ever know to avoid a massive radiation plume they weren't expecting? Particularly if the plume is very large and expanding faster than they can move the ship?

2. How much of the crew would be informed of such a situation? Would there be a risk of panic or mutiny, if all of the crew were permitted to fully understand such circumstances?

3. Given that this is a military vessel, if they are ordered into harm's way (or perhaps ordered to assist since they've already unwittingly suffered irreparable harm), would they say no? Would careers be protected and defended if orders were obeyed?

4. Would it be possible to fake 70 cases of thyroid polyps, leukemia, testicular cancer and uterine bleeding so bad it requires transfusions?

...and as an aside, given that we're introducing the idea that everything might be a hoax, one more question: Given what we've learned about the NSA and Facebook over the past year, how probable is it that a Navy-nuke Facebook group might be astroturfed into an echo chamber aligned with a particular agenda?
Mobile phone numbers cannot be ported from one mobile network in China to another.* Therefore, people are extremely reluctant to switch networks. Otherwise Apple fans would have all switched to China Unicom long ago.

Several of my friends use iPhones on China Mobile. They don't get 3G data speeds because China Mobile uses a different 3G standard, supported only by specific handsets. There are lots of Android-based choices.

Actually, 16/32-bit — the 68000's data bus and ALU were 16-bit, but the instruction set and register set were fully 32-bit.
What is the power utilities number one priority? Profit? Supplying power? Providing reliable power? Serving its customers? Buying back power from PV arrays?

If you answered any of these, you're wrong. The number one priority (at least in the utility I contracted at) was safety. Safety was front and centre in almost all design decisions related to power system control, and was the dominant company culture. Even "low" voltage distribution of 230v is dangerous without the correct equipment and training.

Let's put aside the issues with local transformers and substations - at the end of the day, AC power are relatively straightforward systems (though they are far from simple). The control of those systems is, actually, quite complex, and deals with multiple failure states. Adding PV supply into the mix is problematic. Though well studied, it appears that without better electical signalling (for example, overlaid at the local sub/transformer), Islanding will continue to be an issue.

How do the people who've reached this consensus react to the statement that the lawyers made that they've got at least 70 sailors who are really sick, half of whom have some kind of cancer? Do they think the lawyers are just making that part up? Do they have some alternate explanation for the illnesses, something that doesn't involve all that radiation?

It's interesting that these people you're describing are so concerned with the part that's hard to prove or disprove. The number of sick people seems rather more significant.

pg. 115 - Levison's lawyer has trouble arguing his points with the Judge

He is trying to make it clear that this is not about a system that was designed to make it hard to get snowden's data in the sense that Levison is actually ever arguing that snowden's data is or should be protected or is difficult to retreive. It only becomes difficult to retreive ONLY snowden's data and that is why the govt should be restrained in its options without violating the privacy of 399k others.
I would just point out that most of modern philosophy is not really like this. I think most people think philosophers spend there time arguing about ethics, when this is only one tiny part of philosophy. A good chunk of the current discussion in philosophy of science, for example, centers around epistemology to varying degrees as it relates to current discoveries in genetics and neuroscience. The top philosophers in these fields are far from armchair scientists.

The overlap in philosophy of the mind and computer science is also particularly striking. I studied both in university and often found myself taking what amounted to the same class at the same time, but in two different departments. I work quite a bit with machine learning nowadays, and I learned 90% of the background I needed in my higher level philosophy courses, not my CS courses. I have often thought of CS as something along the lines of "applied philosophy".

Obviously, this is not meant to be disparaging towards CS. I love CS and it is what I have made a career in; I think they are different, but equally interesting and useful.
> This isn't a 'presentation' app, it's not PowerPoint. It's a 'pitch' app. In this context, who gives pitches? That's right, a younger, more casual audience, not 50+ execs.

A pitch is a very popular term in the financial and investment banking(IB) industry. Granted the people making pitches in finance are relatively young, but the audience is usually older. Pitches are usually paired with pitch books[0].

Now it's true that people have a sense of humor. But in these settings you have to let the person being pitched usually make the first move to open the stage for humor or animated language. The risk of offending the people being pitched is usually too great (even in a non IB setting).

I know quite a few teachers/professors/etc. who like using interactive tools who would love this app. Most have a good sense of humor, unfortunately I doubt they would take risks of suggesting intercourse in their classes either (I'd have to ask 'em to confirm).

Aubrey De Grey is younger than I am, but he looks old and haggard, much older than I look (and much older than my younger sister who is almost exactly his age looks). I don't know why people take anti-aging advice from Aubrey De Grey. His advice has meager uptake or support in reliable sources on human medicine.

AFTER EDIT: I see the first reaction to this comment was a silent downvote, which evokes my desire to learn. Now that we've established that you disagree with me, would it be all right for me to ask what facts I should consider to change my opinion that Aubrey De Grey's anti-aging advice is not correct? What positive rationale can you provide for taking his writings on his favorite topic seriously? What evidence can you provide that he is on to something that the National Institute of Aging[1] isn't researching adequately already without him?

[1] http://www.nia.nih.gov/

ONE MORE EDIT: Thanks for the replies. I think the most helpful to me was

As far as I know, Aubrey has not claimed to have invented any working anti-aging treatments so far

because I've been curious for a long time why Aubrey De Grey receives so much mention here on Hacker News whenever research on aging comes up, but so little mention in any of the extensive medical literature I read. So he is one guy with some interesting ideas (interesting to people here, at least) but perhaps just one guy among thousands working on anti-aging ideas. I wish anyone well who is devoting time and attention to reducing the harm of aging processes in human beings, but I try to cast my net searching for information more in the waters of medical reports than among people with a famous online presence as such. Thanks for the follow-up, and for letting me know what you really think about the unedited version of my comment, which still appears at the top here.
strace is one of my favourite tools. I don't need it that often, but it's comforting to know that it's there. Documentation can lie or just not answer my question, the source code might be unavailable or unreadable, but if I have a question that strace can answer, I can rely on it to answer.

Well, there are obvious limits to that argument. Even a hundred years ago, it was common to die in your 60s. Taking on a new career or new relationship at the age of 60 would be ridiculous. Today, it's still a bit unusual but not unheard of.

Given a longer life, I think we would come up with new ways to motivate ourselves, and new challenges. This isn't an insoluble problem, it's a business opportunity for Tony Robbins.

That said I'm not sure a human being could ever fully escape ennui, so maybe there is some upper limit. I don't think 80 years is even close though.

No. This research addresses just one cause of ageing; there are many others.

> It is also interested because it is adding rather fundamental features to it like maps. Yes, yes, all the modern languages have them and Erlang is about to them too!

I don't know whether I'd say Erlang didn't have (hash-)maps before.

Each Erlang process has always had a "process dictionary." If you think of these as equivalent to another language's thread-local variables, this seems like a wrong comparison--and people tend to avoid using the process dictionary for this reason.

But if you think of processes as Erlang's objects, in the OOP sense[1], then the an object's process dictionary is equivalent to that object's "slots", in the Python/Javascript/Lua sense. And so, if you want a (automatically concurrency-safe!) map, you just make a new "map server" object that responds to get and set messages by manipulating its process dictionary. Which is exactly how you'd expect a mutable hashmap object to work in any other language.

Or, you can avoid this low-level stuff by using ETS tables instead, if the difference between O(log N) and O(1) performance doesn't much matter to you... but if you think about it, ETS tables are basically just doing this same thing: creating a separate object/process that responds to messages to hold your mutable state, rather than representing it as an on-stack data structure.

[1] Alan Kay was probably describing something closer to Erlang (or Simula) processes, than Java "objects", with OOP. Here's the unabridged quote: http://userpage.fu-berlin.de/~ram/pub/pub_jf47ht81Ht/doc_kay... . Note especially this part: "I thought of objects being like biological cells and/or individual computers on a network." Both of those conceptions necessarily involve concurrent computation on the part of each "object."

Ask HN: I'm bored with programming, what should I do?
I've been coding for a living for about 15 years and, while there are plenty of days where I learn something new, overall, I'd say I'm actually pretty good at it, and generally quickly earn the respect of my peers wherever I work.

The problem is, I've lost my spark and enthusiasm for the job, BUT, I can't afford NOT to work, and with 3 young kids, I have some pretty significant overheads to meet each month.

I still read HN and other tech sources avidly, so I still have enthusiasm for the industry, in fact, I dream one day of running my own successful tech business. I'm just finding the physical and mental act of programming for a living draining, having done it for several years, I'm in need of a change, and, if I don't change something, I fear I'll burn out.

So, turning to HN for some inspiration. What should I do?
it is exactly that, unfortunately...
The new regulations certainly step up the engineering game, going into uncharted territories. I'm not sure that as a motorsport spectator I like these changes, though; there's something about the sound of the V8s or their predecessor V10s, revving at 20k RPM. It's a large part of what makes motorsport exciting. Compared to that, a 15k RPM 1.6L V6 seems pretty dull, regardless to how well it performs.

It depends on which attack vector you're defending against.

If you're trying to defend against the cellphone (or chasis microphone) attack vector, then you can defintely defend with human audible noise. Your cellphone is going to have an aggressive low pass filter prior to the ADC to prevent aliasing. This will limit the cellphone range to roughly human audible range. The difficulty is in generating sufficient noise at the frequencies required. As the FAQ on the page points out the majority of this lies in +10kHz, so using normal music won't be too effective, but artificial noise is certainly possible.

The Q&A on the linked site answers all sorts relevant questions and is quite enlightening.

In the actual paper is maddening non-specific about how widespread audible range attacks are. Ultrasonic attacks are likely viable against nearly all unprotected machines, however the paper only says that 'some' machines are vulnerable to audible spectrum attacks.
