Nice idea, and I wish them well, but I suspect it will take more than a free gym for every 50,000 people to put a significant dent in Brazil's inequality and health problems.

"If GML was an infant, SGML is the bright youngster who far
exceeds expectations and made its parents too proud, but
XML is the drug-addicted gang member who had committed his
first murder before he had sex, which was rape." -- Erik Naggum

GML is from the late 1960s and is, arguably, easier to read. SGML from the 1980s expanded upon this. XML is essentially just an offshoot of SGML and much less readable than SGML is. For example, here is a valid SGML document:

<anthology>
<poem>
<title>The SICK ROSE
<stanza>
<line>O Rose thou art sick.
<line>The invisible worm,
<line>That flies in the night
<line>In the howling storm:
<stanza>
<line>Has found out thy bed
<line>Of crimson joy:
<line>And his dark secret love
<line>Does thy life destroy.
<poem>
<!-- more poems go here -->
</anthology>

Aside from XML's lineage, there is no shortage of markup languages available with varying levels of readability.
Weird side point, but I'd be really interested to hear how people weight the importance of Wikipedia text vs media vs history. For me the first is 99% of the point, but clearly others feel differently.
Moto E is US$130 now, and will likely go down a decent amount when it's not brand new.

An operating system can retain its memory between reboots using only RAM, as long as the reboots are not "cold" reboots (that is, machine powered off and then back on, or reset through hardware instead of software).

It of course depends on hardware support, but it can be done even today on select platforms.
I prefer not letting people know I'm reading their emails. It's a privacy thing :)
I really really really want a better security model for chrome extensions. As an example, I'd be happy to install this extension if it didn't "have access to" my gmail content, but was somehow able to add DOM matching and mutating callbacks that were run under Gmail. The matching part would be under my control and couldn't be updated by the extension. For example I'd be happy to let this extension mutate any img tag. I'm sure you can find a million holes in this idea, but it would be better than what we have today.
>Maybe we're operating with different notions of "the question of consciousness", but I have to disagree that a perfect simulation of a human mind would dissolve the problem.

Because human brains are magic?

> And by "the problem" I mean the Hard Problem of Consciousness, the issue of how the hell the subjective experience of being arises in a lump of bloody meat (or in anything, really).

You have your answer, the effect of consciousness clearly arises from physical matter that is subject to natural laws of physics and shaped blindly by natural selection. That should tell you that it is quite possible. For example, for a related concept of Free Will, I think we can confidently say that for all intents and purposes we don't have any, and yet our brains produce a very powerful subjective feeling of having it. This is why I think Consciousness is a much simpler problem than it really is. We have a cognitive bias for seeing the world in a very specific way, just as we have a cognitive bias in visualizing 3-dimensional spaces and we have incredible problems visualizing higher dimensions (heck, we can't even visualize a 2-D or 1-D space without embedding it in a 3-D space).

Consciousness and free will are very powerful illusions hard-wired into our brains, unless you think the particles that make us up, somehow don't follow deterministic (or random in case of QM) natural laws?
There are multiple companies/exchanges that can convert BTC to USD, yet prominent merchants only use Coinbase. That's the centralization.
Indeed; a reminder that crony capitalism is not isolated to the US.
Interesting tidbit: a while ago, I was talking about memristors with a physics trained person. And he told me something that really stuck:

It is impossible to make an inductor (coil) without resistance and without capacitance. It is impossible to make a capacitor without some inductance and a little bit of leakage. It is impossible to create a resistor that does not have self-inductance or a bit of capacitance.

If you followed all that and you agree with it (because you've done some electronics) or you've heard of 'parasitic capacitors' and such, then you can see that it must somehow follow that parasitic mem-resistance must have been with us all along, but is such a small effect that we simply failed to notice it. No resistors, capacitors or coils that we normally use exhibits this effect in such a way that we adapt our designs to it to minimize it.

That's in part the reason why it took so long to manifest in a usable form, if the effect would be as devastating as resistance on powerlines, as capacitance on wiring, as induction on large capacitors then we'd have exploited it long ago.

So it's going to be something exceedingly subtle when and if it comes to market.
So the idea is to use a big monolithic multi-API thing as opposed to modular plug-in based system?
But you do have a different word for "think", right?

Google Translate shows multiple, but these three seem most applicable:

ajatella: propose, consider, think about, weigh, cogitate, think
miettiä: think about, think, consider, reflect, contemplate, ponder
luulla: think, believe, suppose, imagine, expect, suspect

The difference between "think" and "compute" is the important distinction being made, and I tend to agree that moving the goal posts does nothing to help decide whether a computer is really capable of thought.
As a lot of things here in Brazil, this looks like not very thought through.

"When you consider the fact that Brazilian diets are commonly high in fat – meat is often eaten for all three meals of the day – it’s no surprise that hypertension, diabetes, cancer, obesity and cardiovascular disease are on the rise."

What about all the serious recent research showing little correlation between fat in diet and all the diseases? EDIT: also, I would add that meat is often eaten in upper classes meals. Meat is a luxury for the better part of our population.

Actually, I believe that there is research showing that physical activities has, at the most, an indirect effect on obesity. Although I can't cite any study here.

Another strange passage:

"What really convinces politicians and funders is evidence. "

Not sure this is true, in Brazil or any other democracy. What really convinces politicians are projects that generate good publicity. Which this one proved it can.

Said that, I think this is indeed a good project and it is a good thing that it is running. But I am inclined to say that the answer to "Can a grand vision of 4,000 free public gyms overcome inequality and fight Brazil’s health crisis? " is no.

I don't see why, from an economics perspective. Sure, the person who lives real close to one school and very distant from the other schools may not have other options so good that they overcome the cost difference of travel, however, the people who live halfway between the two schools will still have that choice. This still ensures that there is competitive pressure on the schools. The thing about competition is that it tends to improves the quality/cost ratio of all offerings, even those that don't "win" the competition.

> cjdns will never be a workable solution for the general public, and I wish people would stop recommending it.

I disagree...I believe in its current state it is not catering to the general public, but it's basically alpha software with a small bootstrapped network. Long-term, the idea is to make things more user friendly and appeal to a wider audience, but it's inaccurate to say it will "never be workable". Recommending it to a highly-technical targeted audience like HN seems entirely appropriate.

I'm using two HAProxy machines and keepalived to ensure that if one goes down, the other takes over.

Because HTTP in general and with that HAProxy is very stateless, this is really easy and safe to do. I've had the opportunity to fail over multiple times already (mainly for software updates, once because of a hardware issue) and I never had any problems with the setup.

I'm a Brazilian and I've seem near my home those 'open gyms' coming up in the latest years.

I never see any instructor, but there is this square just across the street of my house that got some 'gym equipment' for everyone to use.

It's a lovely idea, but (IMHO) this move solely doesn't do much towards better health results. It's nice to bundle some equipment to do better workout where we already exercise, but in the end I feel like it would be more efective to make more of those areas. There is really few good places to workout around here or take a long walk for instance.

I would love to move around in the city in a bicycle. But there is almost no bicycle path, and facing the transit with buses passing centimeters to you is just for the brave.

I think there's STILL debate about whether you can actually make a REAL memristor, or whether you can merely make something that behaves exactly as a memristor would.

So, in theory you can't make one, but in practice you can. Something like that.
Ask HN: My Job or my startup?
I have been working on a start-up the last 10 months or so with a team of two other founders. We have done problem interviews with around 50 target market users, done price anchoring, and have developed part of our MVP. We are currently pursuing getting target users into the app and using it on a daily basis while finishing the MVP, one of the features we are still working on was the #1 problem in the interviews. At what point does it make sense to quit my full time job and focus on building stronger user relationships and finishing development on the app with the ultimate goal of converting the beta users to paying users?
Hello,

Beautiful work.

What is that dot you have over the images that references a product info modal. Where did that concept come from? Did you make it?
strong AI would "render the question of consciousness meaningless"; that's a far stronger claim, and in my opinion, unrealistic.

That's actually a great point many people misunderstand, largely due to nobody pinning down a definition for "Strong AI."

I prefer the term "computational consciousness" instead of Strong AI. It gets the point across better about future AI actually _thinking_ and _experiencing_ instead of having people misconceive AI as just a clever if/else decision tree.

Strong/Hard AI (and human consciousness) is a combinations of algorithms and data. People have hard-wired algorithms for processing data from their senses. Some people have better hard-wired algorithms than others. But, if you take the smartest person alive today back in time and raise them in an isolated environment (i.e. limit their data intake), they won't be the same person and they won't be able to think the same thoughts.

Summary: AI = mostly data, with algorithms to help organize/cluster/recall things. You can't have recall and intent of agency without a self-directed consciousness controlling the internal state<->external world feedback gradient.
"Said that, I think this is indeed a good project and it is a good thing that it is running."

But is it a billion dollars of good?

Especially if the most likely outcome obtains and these turn into 4,000 underused and eventually neglected gyms, eventually resulting in almost all 4,000 being sold at fire sale prices once the government's priorities move on?
WebCL community is geared towards exposing platform OpenCL backed by GPU, that would be stealing their fire.

Though it might still be the smartest thing to do given the poor state and lack of recent progress of GPU OpenCL drivers. Even desktop apps that would like to use OpenCL are just barely limping along. See eg. Blender.
Nice, but I wouldn't confuse static images with the underlying semantic graph of live objects that's not visible in pictures.

Is there an online anthology of C Northcote Parkinson's essays?

My battered 1961 copy contains 10 essays of which the preface says 3 appeared in the Economist and "certain of the others" in Harper's and The Reporter.

My favourites are:

The essay on how to word a job advert: "the perfect advertisement would attract only one reply". Examples are given of job ads that hope to prove sufficiently offputting to the wrong candidates.

The piece about councils. Ideal number of members: 5; any council with more than 20 members is an ineffective showpiece. Illustrated with a historical look at the Privy Council and the size of Cabinets in countries around the world.

The piece on time spent per item in financial meetings, which introduced us to the bike shed. (In the original essay, the bike shed is not the most trivial item on the agenda -- that is the question of whether to serve coffee at meetings, which gets an hour and a quarter's debate, to the bike shed's mere 45 minutes.)

Interestingly, this is exactly what the chief of HP labs said in this video [1]: That lots of papers noted the effect and talked about anomalies, but no-one made the connection to the memristors before them. He also says that the effect is only really noticeable at nano scales (because it needs incredibly high electric fields).

EDIT: on second thought, that's not the case, because the HP memristor is not a memristor in the sense of the of the original paper describing it - it has nothing to do with the magnetic flux. It can only be described with the same set of equations, so, it behaves like a memristor, but is not "actually" a memristor that completes the set [2]. That is, if I understood the video correctly (but I think I did, as the speaker himself talked about a "trick" in the beginning of the video).

Nice to see confirmation of that theory from that high up.

It seemed extremely logical to me when I heard it the first time and like everything else, in retrospect it is blindingly obvious.

I'd hate to see a memristor dropped into a circuit design and being handed the task of 'fixing' spice to produce the correct output. But by the looks of it the usefulness of individual memristors will be quite limited.
You don't need to tell me that companies who've been doing eye tracking for years are ahead of my little homebrew project. I know that, obviously. But if I can prevent even one patent that claims "eye tracking like before, BUT IN A VR HEADSET NOW", I'll consider that a win.
Mutable data does not give you any ability to analyse actions over a period of time. For example: "How many people were active during the month of the Indian Elections?" Can't tell you today, because all the data has been mutated away.

Secondly, mutable data also means that you have less scope of drawing new insights from historic data. (Primarily because you never have historic data)

It's a lesson that doesn't seem to get learned, even after decades of research saying that people start internalizing negative stereotypes, 'reasons' they have been abused, and statements indicating low expectations of them. When people hear 'math is hard', many people don't even try to learn it. When people who consider themselves part of 'group X' hear 'group X is bad at whatever', they don't do 'whatever'. And when 'group Y' hears that they won't amount to anything, many just give up trying. It's destructive, it's horrible, and it is real.

There are a few important things to realize here. Some of those who say these horrible things often don't understand the topics very deeply. As a former, and still peripheral member of various social justice 'communities' (and I quote that because the 'communal' part is often centered around unfocused anger), I see and have seen so many people come to discussions with only talking-point-level understanding who run with it (or are simply running on 'cached thoughts', rather than situational ones.) The other thing, which the author likely knows well, is that in the Oppression Olympics, the author is in the biggest loser group, so is going to be cared about the least. Despite endless blog posts and pleas to end the OO, internecine attacks, ally-bashing, purity tests, knee-jerk responses, and all the other wonders of the SJW world, it goes on. I don't blame the author for exiting. It's part of what made me sideline myself, and many other former dedicated members of these communities.
Depending on skills and inclination, pursuing the right degree at the right university has an expected value very much in excess of $100k over what you might otherwise do. E.g. if you want to be a lawyer and could use this money to pay your way to $PRESTIGIOUS, instead of going to $PODUNK, consider that. (Or, as patio11 says, if you'd otherwise not learn how to code, consider that.)

(Be careful, though - American higher education can consume a lot of money and leave you with very little value. Be doubly careful with law in particular.)
Ford, (NYSE:F), my largest personal holding, reported $1.4 billion dollars in Q1 2014. They currently trade at a valuation of around $67 billion.

Facebook reported (according to Siegler), $642 million last quarter.

So if his argument stands, that a company that earns .64 billion dollars in one quarter should be valued at $168 billion, I should be celebrating an impending 65-bagger, as clearly Ford is soon to be valued at $4.3 TRILLION!
