> Car fuel tanks are made of something like 1-2mm steel.

Many, many car fuel tanks are made of plastic.

It's the position of the tank in the car rather than the material involved that's important.

This is a hard problem for Tesla to solve because their batteries are bigger by volume, really heavy, don't get lighter as they discharge, and don't shape as easily as a liquid, so the bottom of the car is the only really good place for one.

That's why Tesla used the "heavy armor" approach and actually -do- have several mm of metal located beneath the battery, but no armor is perfect.
Right, stationary hands means less energy expended means less stress and less strain. It's just tough to get used to the "nub", it's like learning how to ride a bike at the age of 25, hehe :-)
And whether this is "the big one" or not, with this attitude, we'll never be ready for anything that actually does go seriously wrong. "It hasn't happened before, so it can't happen now" makes for nothing but a great epitaph.

Does it need 25 tons of force or 3 inch hole to get the battery to catch fire?

If the battery container is blend out of shape a bit, would it potentially cause small short in part of the battery somehow? Would that start a fire for the rest of the battery.

If this is the case, wouldn't the probability of car catch fire might be higher?

An easy test might be take a few batteries and start shoot them with nail gun and see it get shorted/heatup/catch fire?

If it does catch fire, put a 5 mm sheet there and see how many nails and how big nails can get it to heat up / catch fire?

If any of the above tests can get the battery catch fire, I would be very concern if I am an Tesla owner.

If it's not too tacky, I'd like to give a plug for the talk I gave at CascadiaJS called "Stop Breaking the Web":

http://m.youtube.com/watch?feature=plpp&p=PLLiioAbFTbKP9CxF9...

If you're developing web apps using JavaScript, especially Angular or Backbone, I'd ask you to take 25 minutes to watch it and understand how important URLs are to the web, and how many JS developers currently treat them as an afterthought.

I work on Ember.js and lots of my thinking stems from that. Even if you don't use Ember, though, you can take these ideas back to your particular JS ecosystem. It's obvious to me that JavaScript is the future of the web, so we need to make sure we're doing our part to be good web citizens.
at this thickness it would be something like aluminum, not steel. Good as a frame material, while softness make it not that good for point penetration resistance (it would be somewhere like 1mm steel equivalent, so seems i was wrong above). 5mm Al cover for 10ftx6ft battery would weight 80kg - doesn't look like there is much room for increasing.

So it doesn't sound like they did a screwy job - that's good to hear (as i said i'm a fanboy of Tesla and think nothing can stop them but their own hubris - when/if it appears), yet it also may mean that there is no easy, "low hanging fruit", way out.

I never sought your approval. You just came out of the blue and told me I was wrong.

> Your usage was wrong.

You are wrong. I don't know why this is so hard for you to accept. Unlike you, I have presented actual academically acceptable evidence for my claim — you might take that as a clue for who's right in this situation.

> If you don't like that, go find another opinion.

I did get another opinion — I looked the word up in the Oxford English Dictionary and it confirmed that I used the word correctly.

The plan is a mail server where the hardware/storage is in my home, opening reverse ssh tunnels for ports 25 and 465 to inexpensive VPSes regularly created and destroyed via APIs, with DNS MX records updated automatically. That way my world-visible MX endpoint will regularly change IP address, and move between US, European, and Australian based datacenters. The VPSes are configured to not store or log anything, and to always attempt to initiate SSL/TLS connection (with STARTSSL SMTP messages).

I'll know which VPS providers I have accounts with (and anybody curious could also find out by watching my zonefile updates), but at any time I won't care where the remote end of the ssh tunnels is or where the MX records are currently pointing.
An End to Modern Medicine As We Know It
Antibiotic overuse and misuse are making these medicines resistant and thereby ineffective. Not long ago, infections that were curable and heretofore took lives now could kill again.
I've flown into Copenhagen, Amsterdam, Cologne, Hanover, Paris, and London, and I do not recall seeing anything like this. I'd think I would remember as it is very alarming-looking.
Yeah you have. Just not physically.

When you exit the secure area of the airport, you usually pass through a corridor with tons of CCTV cameras and a TSA employee. Those cameras and that employee are to keep you from turning around and re-entering the terminal once you've begun the process of exiting.
Engineering lets you model things without having to do experiments. It's possible to know that a car design is more likely to catch fire just by analyzing it. You don't have to wait for thousands of cars to catch fire.

If I were a braver man, I would stand in the middle of a crowded airport security line and yell "BOOM". There are so many potential points of vulnerability in an open society that eternally fighting the last war is absurd.

As it is, I quietly protest in the only way I know: I avoiding flying unless it's impossible, and take road trips instead, despite the dramatically higher safety risks. I've come to deeply loathe the airport experience.
Dear Winamp, thank you for XMMS. Adios!
Sorry but in this scenario maintaining a 5-person skilled IT department was/is imperative. The TCO should of the IT department, even if you hire D. Hartmeier[1] to configure the firewalls, should be negligible compared to the operation's TCO.

That said, in this case I believe that the software to manage the centrifuges is made by Siemens (Germany) and it's written on Windows. So partially it wasn't the consumer's choice to use windows. Even if they used linux, is not hard to think that the NSA could have written a Linux clone worm. The only thing that can keep away such threats is "security" as Schneir mentions here[2] "security is a process" and that process can secure any operating system out there imho.

Well, to quote the article, you can see things like "p is absolutely continuous with respect to the Lebesque measure on En" and hundreds of variable names and sub/superscripts, none of which are intuitively named. It's really hard to argue that anyone who is not in academia would understand this without passing through it multiple times.

That being said, I think mathematicians should be perfectly permitted to do this, seeing as most people who read their papers are themselves, mathematicians. Thus spelling out every dumb detail would probably just be a waste of their time for the one case that the brave soul who is a programmer tries to decipher it.
> Suppose a "hidden truth" turned out not to have been intended by the author — would that make it less true?

Yes, it's not true.

Unless it was a side effect, like if they came from a repressed society X and those effects bleed through to the story. Then there might be unintentional hidden meanings.

The concept art and culture is whatever the user sees it as is a cop out. (Unless the artist intended it that way)

And everything I said is just wrong, before there is no check for living the restricted area.
Thats a great idea. But how to apply this in supper market?

You could only check it after buying, and slapping the so called bio-butcher, if he sells you antibiotic meat, with the meat he sold.
You might want to retest that assumption. Call it a "Big Data" tool and see how you go.

The AI Winter was a long time ago now.
onetwofiveten is not saying that poor black men are unable to make choices. He/she is saying that those choices are made in a context in which "bad" choices -- choices that you and I would not make -- nonetheless seem to make sense to them.

That context is not something we can control, but we as a society do have some impact on it through our public policy choices.

As for the parole violation, I don't think we can evaluate it as "bad behavior" without knowing what restriction he was under and why he was under it. Did it really serve some valid purpose, or was it somewhat arbitrary?

what are the differences? Just a one liner overview would be great, if your time is scarce : ))

Before I knew the word “UI” even existed, I loved making skins for Winamp and various other applications (my 2004 skin, Impulse[1], still shows up on their site). It was a fun, approachable way to create functional pieces of art, and in retrospect taught me a lot about creating a product from start to finish. It was exciting to make something in my bedroom that hundreds of thousands of people around the world would use.

Saddest to me, is that I can’t think of today’s equivalent, a widespread and useful app that encourages its users to tinker and easily modify the interface.

Well in this case, you can also do the normal, in other words adding the differences. The poster asked about finding the differences between points in N-dimensional space in general (he didn't specify for the author's example). But the idea is that your means wouldn't be bucketed into just a couple of values, but have a larger distribution. In any case, it doesn't matter much for this problem, but if you scored it by word count rather than a simple 1 or 0, it would matter.
How smart are these things? Presumably the inside door won't open while someone is in between. Otherwise, I just need to double-tailgate, or simply hire two accomplices.

A large iron maiden (floor-to-ceiling revolving gates, like NYC subways) seems to be a much better, cheaper solution.
The ozone layer survives because people caught it in time and banned the chemicals causing the problem.

We could do the same thing with antibiotic overuse and it would indeed prevent disaster. That's pretty much what every article about the problem advocates, explicitly or implicitly. Well that, and funding more research on new antibiotics, which we're not doing much of right now.

Just waving our hands and trusting to the magic of technology and ingenuity isn't going to get us out of this. We have to actually do something about it.
> Hate the game, not the players.

What about when the players made the rules you hate? The patent system was never intended to be used like this; it has been transformed into this by the very players you are telling us not to hate.
The main difference being that cancer treatment saves your life while eating meat shortens it.

Yes, locked. The point is that you have to wait for one door to close before you can open the other.
Just to explain this a bit, it has to do with relative growth/shrinkage and the base of the positional-numbering system you're using. If you have a random starting value (X) multiplied by a second random factor (Y), most of the time the result will start with a one.

You're basically throwing darts at logarithmic graph paper! The area covered by squares which "start with 1" is larger than the area covered by square which "start with 9".

When I saw the comment, the story had 6 points i.e 5 upvotes.

Even making the huge assumption and leap that it was all MS employees and no one else voted on it who thought it was interesting news, I don't know if 5 counts as a "large contingent".

To be clear, I am not in favor of this campaign and I did not upvote the story.

Why Snapchat is actually undervalued
I think you're glossing over the fact that for a non-trivial problem, you have the pick the right machine learning algorithm from a large set of possibilies, and typically you have to set a number of parameters to make it work. On top of that you have to follow proper methodology to get meaningful results; e.g., to determine whether the accuracy you're getting generalizes to other data as well. I think all of this contributes to making applied machine learning a non-trivial skill. And indeed, AI is just the right background for that, but the point is that you need such a background.
pumping them full of antibiotics under factory farm conditions seems like an awful hack anyway.

it's like running eighty concurrent webserver processes and killing them 100 times per second round-robin because if you don't kill them constantly they will bring down the whole system.

I mean maybe this setup "works" but aren't we really stretching the definition of that word?
Silly, airports can't catch fire.

This was a great post because I've heard of "k-means" but assumed it required more math than my idle curiosity would be willing to handle. I love algorithms, though, and now I feel like I have a handle on this. That's awesome!

However, the higher level point of the post "ML is easy!" seems more than a little disingenuous. Knowing next to nothing about machine learning, obvious questions still come to mind:

Since you start with random points, are you guaranteed to reach a global maximum? Can it get stuck?

How do you know how many clusters you want? How do I pick K?

This assumes that distance in the vector space strongly correlates to "similarity" in the thing I'm trying to understand. How do I know my vector model actually does that? (For example, how does the author know "has some word" is a useful metric for measuring post similarity?)

I like what I got out of the post a lot, but the "this is easy" part only seems easy because it swept the hard part under the rug.
Err, you know the "yelling fire in a movie" is the famous example of speech that is not protected by the First Amendment, right?

MPD ftw
I use to love Amarok back in the 1.4.x days, but after Amarok messed everything up with 2.0, I swore it off and wrote my own XMMS2 client. Clementine wasn't out yet and I decided that the only way to get something that I wouldn't hate would be to write it myself.

These days I just use zsh and mplayer though. Apparently all of my use-cases sum up to "play one or more albums, perhaps shuffling them first". I've given Clementine a shot, and it is quite like Amarok use to be, but now it all seems like clutter.
I am routinely amazed at the improvements the modding community makes even for games that are designed to be unfriendly to mods.

Take Mass Effect 3 for example. The game ships with Origin, which is EA's wannabe Steam online-store/community/DRM. The me3 executable is validated when origin starts up in an attempt to ensure that there's no way to play a modified version of the executable. Modders found a way around this that basically involves playing musical chairs with executable files, and proceeded to mod the heck out of the game from there. The game is not terribly friendly to mods so there's nothing like what you'll see for a game where a toolset has been released, but basic things like texture upgrades (and changes), unlocking and repurposing game assets, modifying weapons, unlocking the in-game console, etc.. (I'm a particular fan of enabling the flycam so you can fly around levels and see how they're built, dynamically loaded, and how they achieve optical effects).

Other games are more mod-friendly. Bethesda's games are one of the standard bearers, and stepping back into one of their games after a year or two can be a completely different experience with the right mods! There are mods that completely rework combat mechanics, add entirely new spell systems, total interface overhauls, you name it! If there's something you don't like about a Bethesda game, odds are you can completely replace it! This raises the replay value of their games tremendously, and all they have to do is release a devkit and be a little bit friendly!

Every once in a while, a botched and buggy game with tremendous potential will be buffed and polished by an obsessed modding community, revealing a classic that the developers were never given time to realize. Games like Troika's Vampire: Bloodlines or Obsidian Entertainment's KOTOR2 are still evolving online. I've been holding off replaying KOTOR2 for years because I know it just keeps getting closer to the game it was meant to be every year.

I'm rambling, but I really respect and love the PC modding community. It truly is something special, and I wish more game companies (EA, I'm looking at you!) would give it the respect (and cooperation) it deserves!
All those companies are there precisely as cover for the few that really drive the lobbying efforts, so that people like you can pop up on the internet and say how it is not just a minority of companies perverting the law in their own favor. You can fall for it or you can see through it (assuming you are not a paid shill in the first place) - I think we should see through it and call it for what it is: a small minority of enormous companies manipulating laws in their own favor and to the detriment of the people.

Regarding 2: even if it has been documented for a while, I don't think it's very widely known. I still see a lot of

models.CharField(max_length=x)

in Django code, where x is usually an arbitrary value only chosen because CharField requires it.
For a 65% to 80% jump, I'd say it depends on the subfield. With NLP (which is basically applied machine learning), it's not uncommon to see algorithms with >80% accuracy.
FTFA:

If you want to change the max length to be larger, postgres will have to rewrite the table, which can take a long time and requires an exclusive table lock for the entirety of the operation.

As of (IIRC) 9.2, this is no longer true. If you alter a varchar column to be narrower than it currently is, you'll rewrite the table. If you make it wider, or convert from varchar(n) to text, you won't.

EDIT: And if you're willing to hack the system catalogs instead of using an ALTER TABLE, you can even get around the rewrite to narrow a varchar(n) column. See: http://stackoverflow.com/a/7732880
> legal rights follow natural rights

Legal rights, as I said previously, may be motivated by beliefs about natural/moral rights, but they are, purely and simply, a decision by the State to use coercive measures to exclude some actions. And they may also not be motivated by any belief about "natural rights". Natural rights, except as a rhetorical device to claim the moral high ground in arguments about what decisions the State should make in terms of imposing coercive power on behalf of one or the other conflicting claimants in a class of actual or hypothetical disputes, don't actually have any direct bearing on, really, anything.

> As you can apply use to the area around you, you can use your natural rights in order to claim property and protect it through force.

You can use your physical capacity to exclude people from actions (whether or not they relate to an entity in which you claim a property right, and whether or not any "natural rights" exist or have any bearing on the situation). You belief about the existence and scope of natural rights might have an impact on where you choose to exercise that physical capacity, but, again, that's pretty much beside the point.

> When you join in a community, you give up some of your natural rights to the state

That's a rather controversial claim; many of those who believe in the existence of "natural rights" also believe that a fundamental distinguishing feature of "natural rights" is that they are inalienable -- that is, they cannot be transferred or surrendered.
I like what this guy is doing :)

I've personally stopped buying any game that is a port just because of past experiences lol. Also it's probably us PC gamers who have certain standards that are more demanding than consoles. An example is the feel of an FPS (half life and the like set that bar)... or just as in the article, the graphics settings.

I've actually been a bit sad lately, because I think the industry has changed so much in the last 10 years. The '95 to '05 run of PC games was awesome [1]... small to mid-sized companies churning out great stuff (especially in some of my favorite genres, like strategy). Then around 2004, I got engulfed in HL2 (+ mods) and WoW, and emerged a few years later to find quite a different PC games market. To me, it was basically now only Blizzard/Valve, with everyone else gone... or making the 'cool' games for console (I guess console gfx finally caught up). Good to see indie/kickstarter stuff lately though!

I miss the days when I would go into a random games store and find gems in the PC games aisle (and I'm not even that old). Last time I tried that it was basically all ports of console games and then the 25 WoW expansions lol.

[1] Some of my favorites from that time: Age of Empires/Mythology, NOLF, Blizz games, Unreal Tournament, Command & Conquer, Red Alert, Valve games, Battlefield, Dungeon Siege, Far Cry, Call of Duty 1, The Sims, Baldur's Gate, Quake... can't remember any more haha.
