I feel like Tesla is a car company only because that's the only way that they can prove to the rest of the industry that their technical innovations work. I always kind of thought that the 'real money' for them wouldn't be in making cars, but licensing their tech to all of the larger automakers.

"Packetbeat agents sniff the traffic between your application processes, parse on the fly protocols like HTTP, MySQL or REDIS and correlate the messages into transactions.

For each transaction, the agents insert a JSON document into Elasticsearch where they are stored and indexed."

How much performance degradation could be expected from constantly inspecting every packet on your network with libpcap, correlating the packets into transactions and then storing information on every transaction in Elasticsearch?

Also: I noticed that the link to Elasticsearch on the "Getting Started" page is broken (it's missing the ":" after "http"). Here's a working link: http://www.elasticsearch.org

I can figure out my code and my gf in one stop?
There's a lot of talk about about Tesla being a startup or a tech company. In reality, they're a car company (albeit one that's doing a few things better/differently), and need to be looked at in that context.

I've been thinking about this a bit lately, more generally. My impression is that what counts as a "tech startup" in the past few years is more of a cultural question than a business, technological, or economic question. Now whether that's a good or bad thing is another question. There is something to the cultural resemblance, though I worry that it's papering over pretty significant differences, which might in some cases be more important than the cultural similarities.

Tech startups are, to some extent, just those new companies that culturally use the language of, and interact with, the social milieu of the startup scene. One has to have a general interest in technology, but it can range from deep to very superficial. Tech startups can be wholly based on developing novel technology; or their level of technology might not extend much further than "has an Android app". They could be bootstrapped capital-light companies, or capital-intensive companies in traditional industries. What seems to matter to the classification is more of a style or culture or attitude.

They aren't really distinguished by using technology, because everyone does that now. They aren't even distinguished by technology being their "thing", because many companies seen as tech startups culturally are actually pretty light on the technology— e.g. AirBnB doesn't really use technology more than any other travel-industry player does... they're mostly a new-business-model play, which happens to deploy the business model through a website, because nearly everything in travel has gone through a website for 10+ years now.

My guess is that we'll start to differentiate again a bit more in the coming years, based on more structural and less cultural factors.

Your Life Sentence (fiction)
"kinetic energy equal to that of ... a 5-ounce (142 g) baseball traveling at about 100 kilometers per hour (60 mph)"

Probably wouldn't notice a thing. You're mostly empty space (on a subatomic level), odds are it wouldn't hit anything, and would just release no more energy than getting hit by a baseball if it did. Sure it's a stunning amount of energy for such a small object, but not much on a human scale. Compare getting hit with a bullet: penetration is damaging only because of what it tears up in the process, when the energy involved (demonstrated by getting shot while wearing a bulletproof vest) is little more than a solid kick. A "hole" of subatomic width doesn't do much damage.

Virtually nothing, I think. I'm not a physicist but 7.5×10^14 eV converts to 120 microjoules. Wikipedia says that one Joule is the energy in a tennis ball moving at 23 km/h (14 mph). Another comparison I've heard is that a joule is about the energy in a strong handclap. This would be about a ten-thousandth of that.

Wolfram Alpha also gives the helpful comparison "0.06 times the mechanical work done pressing a key on a keyboard" so if that helps?

Actually Tesla would have to pay you to own the stock, since they lost money (negative earnings).
The fact that the earth has seen these bombarding us regularly for millions of years does rather imply that the whole "OMG the LHC will make a black hole" panic was unfounded
Ah, it's easy to see why it won't sound like white noise. The standard function is a Fourier series - a sum of sine waves. It's a power series where the b parameter must be an odd positive integer value 7 or greater. If we want the n = 0 case to map to 20 Hz (minimum of human hearing), and the maximum frequency we can hear is 20kHz (valid for children) then the highest term we can hear is the solution to 20000/7^n = 20; 7^n = 1000, n = 3.55, which means that we'll only be able to hear the first three terms.

This will sound quite interesting, but it's a really bad approximation of the Weierstrass function! http://www.wolframalpha.com/input/?i=sin%28x%29+%2B+0.9*sin%...
I likewise timeshift Formula 1 coverage so I can watch with my brothers, sometimes weeks later. This kind of timeshifted community to would be great to participate in.

Spoilers are generally hard to avoid. This year I've given in and accepted spoilers in exchange for following various communities. So far the participation has been worthwhile and knowing race outcomes and other highlights in some cases had made watching an even better experience.
From what I understand, there's a performance gain from doing the drawing directly.
I find it bizzare that people have such specific dreams. Why not just keep your dreams more abstract?

Like:

I want to be in the creative arts vs I want to be a rock star.

I want to own my own business vs I want to have a cupcake cafe.

The more abstract your dreams are the easier you can reach them and honestly the more realistic they are.
Interesting, I was not aware of that! In this case, they chose to downgrade me to a free account.

What happens when two Oh-My-God particles collide?
On my random forays into C++, I saw different things. Here were my three most important optimizations.

1. Replace strings with integers wherever possible. Create a mapping table, use the indexes.

2. Layout related objects close in memory. Even if it requires special data structures to do. Suppose that if I need A I am likely to need B soon. If B is physically close to A, then I am likely to find it in cache, which is about 10x as fast. So, for instance, don't store a tree as a bunch of random pointers. Store it as offsets inside of a fixed container of memory.

3. Process data according to how it is laid out in memory. For instance walk through a vector, don't do random access into it. Again this is all about trying to make sure that stuff is in cache as often as possible.

For the second and third points I found it was a case of do it perfectly or don't worry about it. For example if I am missing cache regularly in three places, fixing one only mades my code 50% faster. Fixing the second one almost doubled my speed. Getting the last one was an order of magnitude speed increase.

Don't be silly. It's probably Romulan ships with a faulty waveguide around the artificial singularity core. Vulcan warp signatures look entirely different, and mostly radiate into subspace.
Is 100K mps on 8 cores considered high for node/websockets microbenchmarking of the socket path?

That doesn't seem like much from past experience writing high-throughput messaging code, and all this is doing is spitting out length-framed messages to a socket.
I read "business friendly" as having a snide tone. Large swaths of the copy left community don't like the concept of business friendliness and I often hear it in the same sentences as "leeches" or "steal."

That said, copy middle, or permissive licenses, or whatever term you want to use, is at least a little more business friendly than copy left.

I personally don't allow copy left code into my applications so I can keep my IP rights clean. I do that for long term option value, aka business reasons.
Currently, the energy density of NiMH batteries is anywhere from 1/2-3/4 of LiIon batteries, so I wouldn't bet on them being used as traction packs for EVs anymore. It'll be interesting to see if more research is done on NiMH after the patents expire though.

> They are very prone to getting stuck in local minima.

That's quite a generalization. A GA's tendency to get stuck in local minima can be mitigated by adjusting population size, selection method/size and rate of mutation -- i.e. increase the randomness of the search.

I don't believe in dirty tricks like you describe, but it's my solemn belief that you're not negotiating unless your goal is to "fuck the other person over," or aim for an unreasonably good deal. Whether you get it or not is an entirely different matter, but that should be the starting point. You'll never get a great deal unless you try for it, or the guy you're negotiating with is an idiot (for which there is there is also a simple strategy).

I don't know why you think landlords try to fuck people over. I've been on both sides of that negotiation and it's almost entirely market driven. You must live in NYC, or maybe moved to SF in the last couple of years, and have encountered landlords who know they have you over a barrel.
Until now, Tesla was not considered an electric car in China for purposes of getting a license plate outside of the auction. They used this to encourage Shanghai consumers to buy domestic EVs. The law's intent at least appeared to encourage local jobs. Since Tesla found a reasonable way around this, sales should grow remarkably. Tesla is planning local production for that market, which probably explains the change in policy.

Also, most people who have cars in these markets prefer to be driven, rather than driving themselves. Vehicles for the Chinese market tend to emphasize back seat comfort and features. Tesla will likely try to make their features more back seat compatible.

PaintCode is meant to replace the need for images by giving you the equivalent code for basic images. Their initial claim to fame with version 1 was being "Retina ready," since the images are drawn in code instead of PNGs. It is a very good way to learn Quartz and CoreGraphics, but not necessarily the best way to learn ObjC.

I used PaintCode in a project I worked once, and it was a lot more work than I wanted for just asking my designer to give me an @2x image. If you work with designers who do vector art already, you're not going to gain much. The StyleKit class is slick, though, so I may revisit this once again.
No, you take the core of emacs and add a pretty shell around it that adds these features you are talking about. Such as quick way to open files, and so on. There is no need to re-invent core text editing.
Who cares how hard a language is to parse if a parser exists?
Why does each worker need a seperate store process? It seems on an 8 core machine max worker count can only be 3 (1 master, 3 workers, 3 stores). If workers had in-memory stores -or at least connect to a Redis server-, with 4 more workers performance should increase.

Here's the story of one guy who's head was in the path of a proton particle beam:

http://boingboing.net/2011/02/22/what-happens-when-yo-6.html

"The radiation absorbed by his head was in the region of 1000 gray. 5 gray worth of X-rays is generally considered fatal, but Bugorski survived and went on to complete his PhD (a proton beam moving near the speed of light has different characteristics from an X-ray!). The side of his face that was burned by the beam's exit has not visibly aged in the years since the accident. "

Note that such a beam contains millions (or a few orders of magnitude more?) of protons. I can't say whether millions of protons with a millionth of the energy as this particle do more or less damage.

This is just a guess, but it shouldn't impact your performance at all. It's just a passive network capture mechanism like wireshark. It will need resources to do all the logging/categorizing/displaying and such, but the rest of the production environment should be unaffected.

Thanks for letting me know though, my brain went with starting at the bottom for some reason rather than the letters.
while I agree with the general sentiment that the idea that the LHC will create a blackhole is silly, surely there is a difference between creating such a particle and simply being in the trajectory of a particle that has already been created.

Depending on the traffic, the CPU usage of the agent could indeed be significant. We're thinking to implement sampling to reduce the effect of this. On the other hand, the agent is not "in-line" so it cannot introduce any latency, only steal CPU time from them.

So, unless you have a single CPU core, it's pretty safe to run in production. It cannot affect the application performance by much.

Thanks for noticing the broken link, we fixed it.
I don't think that follows. The LHC is many, MANY orders of magnitude too weak to produce this kind of thing, but it can produce beams of many protons or, alternatively lead nuclei. Thus, it could conceivably create entirely different effects.
Ask HN: any Googlers here can explain why no Python 3?
None of Google's SDKs (i.e. for Compute Engine) support Python 3.

Are there any Googlers here on HN who can give insight as to why?

How far into the future do we have to go till Google SDKs provide Python 3 support?
Depends on your use. For open source work, Github's community probably makes it better. For closed source, personal work, as mentioned elsewhere, only being limited by size of repos is much better. For a business, I suppose it depends: Bitbucket is part of Atlassian, a company many development shops already interact with, however, the Github community can be a good source for recruiting.

On Death and Dying
by Elisabeth Kubler-Ross

Because my ex-wife of 21 years and the mother of my 3 children is quickly being taken away by cancer. I am a man of science and I recognized much of what was going down, and she wanted to know it all, every detail, she doesn't want us to hide a thing. It's horrifying to share such things with a woman I have loved for 30 years. But she trusts me not to lie to her, she wants to know so she can prepare. One of her sisters works in a breast cancer clinic and knows how this goes all too well. We've all tried hard to help her but the reality is that at some point it's just too late. I feel for the caretakers who deal with this on daily basis, I can barely handle one case I can’t imagine dealing with it daily and thousands of cases.

I have dealt with death in many forms, from instant "Oh by the way this person passed today" and over time. They all suck, but if you're lucky dealing with death over time can be a bittersweet gift for everyone involved. You have time to share and say goodbye and talk about things we all forget to say to each other each day. My children are devastated but again, none of us know when we'll go, a taxi driver could hit me while I’m walking to work tomorrow. The challenge is the balance, we each want and need to believe we live a life that includes tomorrow and these patients are told the number of tomorrows are much smaller then each of us assumes when we get up in the morning. It's the dichotomy of life, without death life means nothing, but with death comes so much grief, pain and sorrow.

This story touches me because I too understand what's ahead and as it has unfolded I want to hate myself for being right. There is the science of what is happening and the real human tragedy of it all.

This seems like a very strange article to run across on Hacker News and to be 100% honest I was here trying hard to avoid thinking about what is unfolding in my family’s life. All I can say is thank you to the poster for pointing this article out. I think there is an interesting juxtaposition between the knowledge every Hacker wants to know and how you can’t unlearn once you have learned something. Imagine the horror of understanding all the technical details of what’s happening to your loved one while being totally helpless to do anything about it. Some say that ignorance is bliss, and maybe it is for some people. I think the big question is do you want to know? Or do you choose ignorance? For me, knowing and understanding has always been a blessing with a certain weight that I am willing to carry, even if it means understanding how someone I’ve loved for 30 years is slowly dying. At least when she’s gone I will not have to guess what happened…
Wikipedia actually says the kinetic energy of the particle is 50 Joules (3*10^20 eV) or equivalent to slightly over quarter pound ball (142 grams) traveling at about 100 km/h.

Could increased solar radiation cause the rise in cancer?
I think longer lifespans also increase the risk of cancer, but is this also a possibility?
Total energy is not the only factor in determining damage. The rapid movement of a bullet through flesh does extra damage due to the shockwave it creates.

Similarly, if you drop a hard drive on carpet it's probably okay, but if you drop it on concrete, you're likely to have damaged it and even deformed the case, even though in both cases the total energy to stop the drive is the same.
Do you have a masters / 5 years of experience?
The idea that it would create a black hole isn't silly, it could well do. The silly bit is the thought that it would be dangerous if it did, given particle collisions at higher energies than the LHC happen regularly in the atmosphere and there is nothing particularly special about the LHC ones, bar the fact they are in a massive detector.
“I've come up with a set of rules that describe our reactions to technologies:
1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
2. Anything that's invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
3. Anything invented after you're thirty-five is against the natural order of things.”

It looks good, looks like you have put a lot of work into it. Why would I use this rather than the "Google Spreadsheet API"?

What would you expect it to do exactly? Remove all untagged images?
Not sure what you mean by this, since your comment has no context -- there are no limits or sums in the link. However, even the humble Riemann integral would be able to find the area under the graph of a bounded function on a compact interval which is continuous on a set of full Lebesgue measure. Any other function only has a "well-defined area" for some seriously stunted notion of area; you can integrate more functions with a different integral, but what one calls a "well-defined area" pretty much depends on what kind of integral you're using at that point.
