I like your optimism, but realistically self driving trucks on American highways are a long way off. How will the trucks refuel? How will they handle loading and unloading? How will they handle inclement weather? What is the insurance liability for putting them on public roads? Who will be sued when a driverless truck crashes into another car (at fault or not)?

Even Mercedes says in that article, "the Highway Pilot system could be launched into production trucks 'as early as 2025 if conditions permit'." Which is basically corporate speak for, "we have no idea if this will ever launch, but it will get investors excited now."
It's not sharing knowledge it's spreading "theories" that are well known to be incorrect. Spreading pseudo science, regardless of how much you believe in it, is not a good thing.

These people are great at constructing a narrative that everyone would love to believe. Wouldn't it be great if this single thing was the cause of ALL of these aliments? Unfortunately life doesn't work that way but our minds are great at drawing invalid correlations.

I know this might sound pretty stupid but at first glance it's not completely obvious that the words listed below the search box are the domain extensions. A lot of folks not in the domain industry have no idea there are so many possible extensions. I think it's because I'm used to seeing exts listed with the preceding dot.

Every TOS says something like that, and there are reasonable interpretations that don't include "we will silently break your shit". Even if he had read it, this particular failure case might not have occurred to him.

The third option, one between "you're stupid" and hiding the truth, is to not be a dick about it. The only way people get to the point of being experts is by making a lot of mistakes. If you'd like somebody to listen to your wisdom, there are better approaches than starting out with "that was pretty stupid of you". Especially when it was not in fact pretty stupid of him.
In other words, it equivocates: http://en.wikipedia.org/wiki/Equivocation Wikipedia concentrates on the fallacy angle... in this case it isn't a fallacy, it's sloganeering, since the point is to encourage the viewer to be confused and dig into the two different meanings being used. I think it's not likely to work too well, though.

> Do you know the difference between pseudoscience and a soft science? I don't think you do.

Science follows a well known process. There are no hard or soft sciences. There is one that follows evidence and another that's pseudo science bullshit. With great claims comes great evidence and your soft science example not only lacks proper, vetted scientific evidence but is actually complete bullshit that simply fits with your cultural belief.
I would like to know how they kept the battery alive for over a year with all that power-hungry stuff in there...
I believe the opposite should be true.

The knowledge that resides in my property, whether it be my head or my computer, is my own. I do not grant anybody the right to modify or delete that, and I would not force you to delete your memory or files either.

It is your responsibility to keep your privacy, and those who invade it illegally should be punished accordingly. However, once the information is out there, let it stay out there. The economic and moral-hazard cost of the kind of "data protection" scheme that the author espouses is detrimental.
So don't bother trying to make it better because it can never be perfect?

There are multiple orders of magnitude difference in the effort needed to completely rewrite an entire API implementation in this other language vs. adding some annotations to the existing code. Sure it can't catch some really dirty type abuse like that, but it would let you identify when it is happening so you can prioritize your focus accordingly.
It would be great if you could release the various native bindings (OpenGL etc.) as generic packages. They look very useful outside of Azul3D.
> If you would like to inform me of why it's complete bullshit, I would love to hear. Your comment as it stands adds no value which I think is the reason why you were downvoted (I didn't personally) -- not because people "take sides" with the article.

My problem with this is I would be on HN, Reddit and other places all day. With every extraordinary claim someone makes it can take actual science a few minutes to explain (this is why extraordinary claims should always come with extraordinary evidence otherwise you're just wasting everyone's time like this article). Pseudo science is incredibly easy to generate; you just find something that makes easy correlations (regardless of their validity) and fits within a narrative people love and you're done. Science then has to go through each item and explain why each one is wrong.

I shouldn't have to go through articles like this and look up and source each piece that's incorrect; if readers simply apply some critical thinking and do a little investigation on their own (and, hey, actually READ a REAL study once in a while so you can see what a good study and a bad study looks like) they can see right through it.

I don't have much experience with HN and pseudo science articles; because this crowd is usually really smart I kinda assumed it would have been really easy to tell this was bullshit.
> Build your own by computing the pairwise distance matrix of your entries, then reducing this matrix through PCA to an appropriate number of components (the length of your hash).

You are kidding right ? I cant imagine anyone seriously suggesting PCA on a half a million by half a million matrix, or evaluating this matrix in the first place.

This actually a fairly actively researched topic: whether edit distance can be embedded, even if approximately in a vector space. It has been surprisingly resistant to such efforts. Yes there are some results but nothing very satisfactory.

Edit distance is a metric, so it was believed it would easy to map individual strings to vectors, such that the distance between two vectors was same as, or close to the edit distance between the corresponding strings. What we want, then, is an (approximate) isomorphism between these two metric spaces. In addition, in the interest of size we would like these vectors to be of small dimension. If the required dimension is high it would defeat the purpose if the string to vector map needs to be stored. Unfortunately it seems edit distance is resistant to isomorphism to a low-dimensional vector space. There is also this question which metric do we use in the vector space, Euclidean, Manhattan...? there are some results on the L1, i.e. embedding on a vector space with Manhattan distances.

Fun story: was an intern in Google's spelling correction team once upon a time long ago. So I was explaining what I was doing, the person I was explaining it to was thoroughly unimpressed: "So whats the big deal, you know/hear the word and write down the spelling". It made me realize how difficult spelling in English is compared to some of the other languages. The variability in the map from phonemes to spelling is quite high in English. This person was Italian, he told me Italian has a lot less variability in this regard.

This paper seems to give an interesting perspective: http://intermodal.transportation.org/Documents/brown.pdf

It comes down to highway transportation being massively subsidized in the US, to the detriment of rail. So rail is cheaper but much higher latency than trucking, with the potential for long and unpredictable delays.
Wow. Neat!
You always need to make some assumption about the causal process before you can infer causality from evidence.

For example, take a randomized trial, where half of patients are given a drug, and half a placebo. If we define Y to be the outcome of interest, and X to be 0 when the patient received the placebo and 1 when they received the drug, then a positive outcome would be a correlation between X and Y. A person might object that "correlation does not imply causation", however, we know enough about the causal process involved, to infer that if Y and X are correlated, this must be because X caused Y.

There are many other ways that causation can be inferred, such as instrumental variables, regression discontinuity, or panel regressions. However all these methods require making an assumption about the causal process underlying the statistical distribution. Whether these assumptions are correct is often a matter for debate.
The points that differentiate us depend on your specific application. We have robust routing/turn by turn nav, offline maps, data visualization (heat maps) plus a whole bunch of other common features (custom styling, for example).

Definitely check out our dev site, which admittedly lacks some polish but is coming along (http://developer.skobbler.com/) and let me know if you'd like to talk to one of our SDK guys - they always want to talk to devs about their specific use cases.

> in the U.S., that would be 0.2 IQ points roughly per person..

These IQ points are not equally distributed. The poor and the very poor will suffer far more from these problems - they are likely a rather small minority in the U.S. Wikipedia says 13.5%: Then it would be at least 1 IQ point.

In reality a small but really poor minority will suffer far more from these problems because they don't have access to better alternatives or lack the education to even be able to assess their situation.

The problem with /almost no/ risk is that we don't know. In regards to chemical substances very small doses can also have an effect. Can't we be at least honest?

I don't know for sure if this would help or not but why don't we forbid chemicals for wider use until they are proven as not problematical? And why don't we keep an eye on pollution e.g. in flats as a requirement for renting them?

Is it unreasonable to be cautious in these matters? After learning about the history of industrialization?

As is it now it looks like a matter of class and income and education and this should really not be the case.

Those of us who studied philosophy seriously can tell from the content of the article that the author has not. Thus, it's pretty trivial that he misuses a technical logic term.
Great opportunity to clean the cabal hell I was in. This time I can install you, Vector module!
Automation doesn't mean having to solve every problem simultaneously. You can still pay a driver to stay with the truck, and handle the fueling and loading. Just being able to keep the truck moving while the driver is required by law to rest will be a huge win.

Prove the article wrong if you are so compelled to do so. Part of the reason I share things on HN is for the discussion it creates, which expands my knowledge so I can form educated opinions. I appreciate this aspect of HN, it's why I keep coming back so please, inform me with some links, resources, or research and relieve my of my pseudo-scientific ignorance or stop telling me I'm wrong.
Bandwagon, based in NY, has been doing this kind of ridesharing. They pointed out that Uber/Lyft's 'ridesharing' model wasn't really ridesharing (now it kinda is). See https://medium.com/@HiBandwagon

Yes, the author is describing the problem of induction. There are two major works of Hume that take on the subject, but the most recent popular work I've read is the black swan by nassim taleb.

I'm on my phone now, but I could give a short summery of the problem, and how I think it is intractable if people are interested.
How To Never Check Luggage Again
You don't seem to understand much about science. The way bad claims get dealt with in science is by providing better data and better analysis. A random anonymous dude pissing all over something doesn't qualify in either regard.

It's reasonable to think there's some cost to widespread use of various chemicals. E.g., lead's neurotoxicity is well studied. I think it's therefore reasonable to try to come up with a best estimate of the total cost. Nobody's expecting an estimate like this to be perfect. As long as it's better than the existing estimate, it's a useful contribution.

I don't even understand what your counter-claim is. That all industrial chemicals have zero neurological harm? That neurological harm exists but is entirely unestimatable? That the harm is estimatable but is significantly lower or higher?

By all means criticize, but just being a content-free dick isn't useful criticism. And following it up with name-calling isn't helping.
I was thinking also if they were covered by #3, but I am not sure:

>> 3) A lack of other plausible explanations

This means that there are not other parameters involved, satisfying the other two criteria, that can also plausibly "explain" the measured effect. In the example I gave, there may not be any such other available correlation.

That the analyst picked the plausible cause by hunting though a large number of others is by itself not a plausible explanation asked for by #3.
The collar sends its location every 3 hours = 7 times per day = 2555 times over a year, for a couple of seconds each time. If on average each wake up lasts 5 seconds, that's only 3.5 hours over the year, so definitely within the range of commercial batteries.
A deep man believes in miracles, waits for them, believes in magic, believes that the orator will decompose his adversary; believes that the evil eye can wither, that the heart's blessing can heal; that love can exalt talent; can overcome all odds.

Oh dear.

Let's start from the beginning, what is this well known process that science follows?
I don't think so, since many of the pesticides being blamed have been in use long before CCD appeared.

Elliptic curves offer plenty of side channel opportunities; they aren't intrinsic to RSA.

ECC is good, better than RSA, but what this paper militates for is leak-resistant cryptography implementations, not ECC in particular.
The Second Law of Thermodynamics only applies to closed systems. We have a giant nuclear star nearby bathing us in untold amounts of energy -- certainly enough to stave off disorder for a long, long time.
My semi-retired parents were lured in by the claims of making upwards of 80K a year if you worked hard enough. They did it for about three years and quit with more debt than when they started. You can only make decent money if you own your own rig, which costs as much as a house. Trucking is heavily regulated, but in ways that dump all the problems on the drivers. You are in competition with other drivers, which pretty much guarantees you're going to be cooking the books increasingly regulated-away ways, not to mention how dangerous it is.

There are exceptions to everything though, if you've been on the road long enough you make more money per mile as you build up a reputation, or you can make money money working for fedex or doing hazardous materials shipping, but it takes years of toiling in shit conditions for low pay to get to that point.

They also told me that they met a lot of people who clearly hadn't done the math, and were losing money instead of making it despite working very hard. The cost of the truck alone puts you in massive debt with no guarantee of work to pay it off.

As far as automating it, maybe in 20 years it will be viable. It's not useful to talk about that today.
The problem with many of these is that, as in everything else, the dose makes the poison. Fluoride is a perfect example: too little and your bones are weak & tooth decay sets in easily, too much and you get fluoridosis. Just the right amount (which is a reasonably large range) and you're healthy.

Maganese is the same, it's an essential trace nutrient for pretty much all living things, and you'll die without it, but too much will kill you.

The most dangerous agricultural pesticides are the neonicotinoids, and they're used in organic farming. They tend to decay quickly, so if the food is properly managed and they're not applied too late they won't be found in the food.

Now, not everything that is dangerous is necessary. There's no benefit from eating mercury, for example, but there are always safe exposure levels. Some compounds bio-accumulate, so the safe exposure levels have to be set for a lifetime. Most organic mercury compounds are of this sort, and due to their extreme toxicity the safe exposure levels are very low.
It does not use GTK+ on a Mac, it uses Cocoa, so it is fully native. Read the docs.
Not saying that fluoride is necessarily bad, but brushing and spitting toothpaste is different from drinking gallons of fluoridated water each week.
You won't make a lot of friends here with this kind of reasoning. Please refute the article in a way that is at least somewhat open to scrutiny from the wider audience. That should at least include concrete examples and preferably sourced rebuttal of said claims.

Calling something "pseudo science bullshit" because of "science"... is a lot more similar to pseudoscience than having an actual sourced debate based on concrete examples.
The author is pretty off-base by calling L. Sprague de Camp "strange."

It's a fun little book.
Great example really. Basically highlighting my message; it can be done (and can be awesome- machined parts are top-quality) but the Huayra costs $1.3M.
Spamcop retiring webmail service
The solution I'd like to see isn't payments but bonds. E.g., on every email I send I can offer $5. If the recipient thinks the email isn't worthwhile, they can claim the $5 for themselves. If the balance for my bond account doesn't have enough money to cover the bond, that's a great signal that the email is spam.

Legitimate email would still end up being free, but spammers would have a much harder time getting mail through. And large mailing lists would be forced to be pretty responsible. Or to offer very small amounts per mail, which would be a great signal to file something under "promotions".

By the way, for those that don't recognize the name, the "ultra-secure" email service is Lavabit, that was secure only by pinky-swear (that is, they just promised to encrypt the emails they were seeing).
It's using native Cocoa controls, so I'm not sure why you don't think it looks native.
Subject: Important Announcement about SpamCop Email Service Changes - Action Required
Date: Sat, 9 Aug 2014 21:46:21 -0400 (EDT)
From: SpamCop Email <questions@spamcop.net>
To: undisclosed-recipients:;

First of all, thank you for using SpamCop Email! We want to announce some important changes that will affect how you use your SpamCop Email account.

For over 12 years, Corporate Email Services has been partnering with SpamCop to provide webmail service with spam filtering via the SpamCop Email System for our users. Back then, spam filtering was rare. We heard story after story about how our service rescued people from unfiltered email. Nowadays, webmail service with spam filtering has become the norm in the general public. As such, the need for the webmail service with SpamCop filtered email has decreased.

Due to these reasons, we have decided to retire the SpamCop Email System and its webmail service; while SpamCop will continue to focus on providing the World's best spam reporting platform and blacklist for the community.

As of September 30, 2014 (Tuesday) 6pm ET, the current SpamCop Email service will be converted to email forwarding-only with spam filtered by SpamCop for all existing SpamCop Email users. Namely, all email received at a spamcop.net, cesmail.net, or cqmail.net address will be forwarded to your specified email address after spam filtering by SpamCop. You will be able to continue to use your email addresses like before, but you will need to read the email on your designated email account, instead of the SpamCop Email System webmail interface (https://webmail.spamcop.net). If you are already forwarding your email elsewhere, it will continue to work just like before. If your email program is set to download your email from the SpamCop system, after you start forwarding your email elsewhere, you will need to update your email program to download from there. SpamCop will no longer provide IMAP or POP service.

Please be informed that you will continue to be able to submit spam to SpamCop via the "Report Spam" feature on spamcop.net, or forward your spam using your dedicated spam submission address shown on your SpamCop reporting account. Indeed, you are highly encouraged to do so as your spam report will not only help improve spam filtering for your email; it also helps SpamCop to fight spam for the World!

In the meantime, it is important for you to set up a forwarding address on your SpamCop Email account by September 30, 2014 (Tuesday) 6pm ET. Otherwise, any email sent to your spamcop.net, cesmail.net, or cqmail.net address will be dropped and not be delivered. To register a forwarding address, please login via https://webmail.spamcop.net; click "Options" > "SpamCop Tools".

If you have any further questions or concerns, please send them to questions@spamcop.net
dang, please add "Don't make snarky and irrelevant claims about Reddit and its similarity to HN" to the guidelines.
