all the machinery of the SR is valid only on the background of the fixed spacetime. Once you start to massage the spacetime itself, the SR is only approximation which is good only to the extent of how good fixed spacetime model is approximation of your real spacetime.
Edit: Nevermind - I just read to the end, Piwik can auto-update to latest 1.12. Missed that when cross-reading and trying it myself while reading.

The guide and the mentioned Github repo use Piwik 1.5.1. There are several security issues with this version (perhaps many more): http://www.cvedetails.com/vulnerability-list/vendor_id-9612/...
Latest version is 1.12 - I advise against this "simple" solution to use Piwik. Perhaps there is a github repo with the latest Piwik?

I've been trying to find an outside security camera for years my only two requirements are 1. resolution greater than 640x480 2. able to be used outside in temperatures lower than 0°C (preferably -20°C).

There's nothing out there and anything close is thousands of dollars and commercial/industrial only.
Is the newspaper report non-factual? It even mentions the researcher's caveat not to use cocaine during pregnancy.

"Hurt, who is also a professor of pediatrics at the University of Pennsylvania, is always quick to point out that cocaine can have devastating effects on pregnancy."
Also because they want a phone that is also suitable to be someones main computing device. So if they can get smartphone hardware makers a reason to push into higher spec'ed devices by demonstrating a market and providing a blueprint, that'd be a big win for them as it creates a bigger need for Ubuntu vs. "just" Android or alternatives.
Besides the C# compiler being able to infer types in almost every situation.
I've set up my own home security monitoring in the past using a camera, Zoneminder, and other tools.

Zoneminder is not that great, and I would love to have a packaged commercial solution which isn't too locked down from it's owner. I think there are nice opportunities for business in this area.

That all said, I hate gimicky javash*t websites like this. If I have to noscript-enable sites like jquery.com, your site probably is too sleazy for me to look at. Stop hiding your product behind cheesy effects.
Yeah, your right to an extent. The point I was trying to make is not that C# is better than those other languages. More that I was looking to those languages thinking C# was the problem when in fact it was the libraries I was using that were the problem.
When I had an analyst job straight out of school I found myself collaborating and getting involved with a lot of different projects to get my programming 'fix'. Once I become a full-time developer those side-projects slowly vanished and now I find myself doing one-off programs that help me be more efficient.
>I'd be much more optimistic about the plausibility of a proposed warp technology that only lets you go FTL relative to the implicit reference frame of the distant stars.

That sounds like a stationary ether; where there is some 'true' reference frame in the universe. The main intuition behind relativity is that there is no preferred reference frame.

This is a bit of a caricature, but the way I see it is there is a valley between two hills. The free speech guys are at the top of one hill, and the social conservatives are at the top of the other. Neither group realizes that the other group lives exclusively on the opposing hill, because to them, anybody they've ever met from the valley seems just like the people who live on the other hill. So they're both afraid of sliding down the slope into oblivion. (Imagine what will happen if we let our girls go to school! Imagine what will happen if we don't let people advocate genocide!) Meanwhile a lot of us are calling up from the valley and saying, "Hey, it's really pretty nice down here, and your hills don't seem that big anyway, so why don't you join us?"
> Harold G. White, a NASA physicist, gets ideas for his warp field from a Star Trek starship concept.

It is ridiculous to think that physicists get any ideas from science fiction. It happens the other way around. All he did was use it in a presentation. I'm nerd raging like hell here.

Why do you think they have poor reading skills? Perhaps they wanted to throw in a little extra, but not the next tier up at $10,000.

Remember, you can donate at any level you want. If someone donated $1000, they would probably chose the $830 option to give more people a chance to get the $600 option.

Remember, you shouldn't think of Kickstarter or Indiegogo projects as a pre-order. It's a donation to a project that you think is worthy; where you may get a substantial reward if that project goes well.

Fascinating.

Definitely several things we can learn from here. We have to do something similar, though we're still at a much smaller scale. That said, the wall'o'scaling is looming large and we're finding that even initial steps of building our own hardware is paying dividends.

I'm quite interested in the Disk I/O lesson's you've learned, specially when dealing with large amounts of RAM. We have to store large indexed data stores (NoSQL, usually Redis) for persisten, extremely high-speed access. A lot to learn here from what you did with SSD's to back that up, especially the lack of RAID.
I don't see your moral high ground here. Snapchat never opened their service and then closed it on you leaving you stranded. They have a service that you reverse engineered knowing it was a closed service and they sent you a pretty nice letter asking you to stop. Should they have made their service more secure? Yes. Does that give you the moral high ground? Hell no.

But, I personally wouldn't worry about it. If they really felt strongly they would send something to GitHub asking to have your project removed. If GitHub takes it down that means they are either being douchey and covering their butts, or they believe the request has legal merit.
We didn't raise any angel or non-institutional rounds -- Series A was our first round of funding.
PetaPoco is awesome and I tested against it for performance (it's a little bit faster).

Some things this has that PetaPoco doesn't are expression visitors for the where clauses and the concept of referenced objects or child collections.
Yes, the instructions specifically say that a transcript is sufficient documentation. Most universities have an easy way to request one (often online), and they usually keep the paperwork even if you didn't graduate, at least if you attended in the post-digitized-records age. Searching for [site:uni.edu transcript request] should turn up the instructions.
I already allowed for that case; I said (several levels upthread) if there's a benefit to the mother that outweighs the risk of harm to the child, then the alcohol use is justified.

That said, AFAIK whatever benefits have been found for alcoholic beverages are not due to the alcohol, but to some other substance that happens to be in the beverage (for example, antioxidants in red wine). If there is a way to get the other substance without the alcohol, that would seem to be preferable since it eliminates the risk without sacrificing the benefit.
Does Upton have any way of dealing with JavaScript or ajax calls? For a lot of the scraping I do in Python, this is crucial for me. I use Selenium's Webdriver (along with beautiful soup or lxml) now for that - definitely open to other options.
Hold on a second: ... "how Greg KH should be tougher on people who contribute patches to -stable" ...

I don't know about you but bar for patches going into stable is that much higher. If people futzing about making crap code they can use it on their own servers, but when patching stable - they should fall in line or submit their code to development branches.

Adding code to the kernel might be fine if you futzing about with your own server, but I sure as hell don't want Linus & Co. letting their guard down because they might hurt someone's feelings.

I've worked with kind of Linus and I have learned from them far more than from most of considerate and gentle minded people(there are exceptions though).

That's no excuse for an $800 price tag. It just means they're charging customers for their bad decisions (as in not using others' hardware).

Cloudflare is a CDN with extra bells and whistles.

A CDN is a way to off-load the bulk of the requests to your webserver by moving the content as close as possible to your end-users, thus reducing the number of hops required to get to the content, which in return increases end-user satisfaction with your product due to a decrease in page load time.

The theory is that if a user gets a snappy service they are more willing to spend their money, and so e-commerce sites and sites that tend to monetize their users in some way find benefits in using services like these.

I hope that explains it adequately. To label cloudflare a mere CDN is a dis-service to them but for explanation purposes it might as well be, I'm sure someone from CloudFlare is able to give a much better explanation of just why their offering is not just an ordinary CDN but goes much further than that.
>You imply that we can't speak ill of Marissa Mayer because she is a woman.

No, you can speak all the ill of Marissa Mayer you want. Effectively saying, "She's a woman," as a way to speak ill of her is bogus, though.

>Now, you, on the other hand, reduce Marissa Mayer to a gender. Someone weak that needs to be protected and treated with care in comment fields.

Nobody is being "protected," least of all Marissa Mayer. Women who aren't in the industry because of pervasive sexism obviously can't speak for themselves to combat that sexism, so other people have to do it.
People really get their pants in a bunch about Linus' abrasive personality. I wouldnt want to work for him, but on an open source project that he has lead for over a decade I think its a pretty clear cut case of 'vote with your feet'.

Somehow with this management style he has managed to produce the largest open source OS project in the wild... I agree with everyone doesnt need to be a dick just because linus is but we definitely cant claim this kind of approach cant work

Snapchat probably does not want to break all of their deployed-and-delivered apps.

If they shipped the app/service without a "force the user to update" feature, they would risk leaving thousands of users in the dark.

And if they did modify their protocol, it would probably get reverse-engineered again, either by the OP or somebody else.
C&D's are usually courtesies to avoid prosecution, rather than legally required. (DMCA takedown notices have particular effect with regard to safe harbor, which -- because the DMCA is involved -- may be what you are thinking of, but this isn't a safe harbor issue; it would be if they were trying to get github to take it down, but that's not what is going on here.)
Just like trying to fix code...

I'd rather see an explosion when I'm wrong and nothing when I'm right rather than the opposite.
I just want to mention that Cron archiving really does wonders for performance.

I've got a site that is receiving nearly 10,000 daily uniques since Google's last [panda|penguin|whatever] update in May, and while Piwik's performance was not terrible, setting up the cron a few weeks ago made the whole experience very snappy.

I've recently experimented with using functional reactive programming to handle the events of a game. I've found it allows for a greater degree of abstraction than an event loop with callbacks, in the same way that higher-level functions like map/filter/reduce provide an abstraction over iteration.
Your third paragraph is a nice way to think about FTL. Actually it causes quite interesting problems to define FTL, since nothing special happens locally.

> But one thing I could not really figure out is whether this so-called FTL travel has the potential to violate causality, because I don't fully understand how causality and FTL are related.

They are not directly related, as I wrote above, nothing special happens except you find a 'shortcut.' So at every point there is still a nice lightcone ( locally) and every event is caused by events in its past lightcone. However, you can have global causality violation, that is closed timelike curves, a fancy way to talk about timetravel. The idea is, that you travel always forward in time and you reach the same space time point at which you started. Much in the same way that you can travel always forward on a tire (torus) and still reach your starting point. Something like this may or may not happen on a metric which permits FTL, for example the Alcubierre metric does not permit travel on such curves. [1] But it would actually be easy to perform the same analysis on a Godel solution [2], which would permit closed timelike curves.

Edith: Added the comment about the Godel solution.

FWIW I have absolutely NO interest in contributing to any project Linus is managing - I will not do it. The only reason is his behavior which is unnecessary and of little honor.
Yeah, that's part of the reason why I said that "we'll be able to solve a greater number of problems by 'defin[ing] your goal, and that's about it'". Progress will happen at a steady rate, but the problem space will expand even faster.
Is RethinkDB suitable for CRUD applications?
No one is suggesting they let their guard down. You can keep your guard up and still maintain quality.

> I've worked with kind of Linus and I have learned from them far more than from most of considerate and gentle minded people(there are exceptions though).

That's because it's easier to act that way for most individuals. It takes real talent to balance the two.
Yeah, that's been my billionaire fantasy for a while now. The goal line could be just a design that a panel of esteemed physicists and engineers deems workable.
AFAICT, YQL can only handle scraping individual pages that way.

Upton can scrape a whole set of pages. If you have a page that lists the pages you're interested in; suppose you're interested in HN commenters on front page posts, you could specify the front page URL and a selector for links to comment pages, and Upton would automatically scrape those pages and return them to you.

Upton could even write the commenter names to a CSV for you with just a filename and a CSS selector/XPath expression.

It's not stuff you couldn't do with YQL or Python/BeautifulSoup. But it's stuff that I didn't want to have to write over and over each time I wrote a new scraper.
Nope. Sorry. :)

While I'm sure this would be possible, I think a node.js scraper would probably be a better fit for that sort of a project.
If the handedness decision really was "arbitrary" and OpenGL had set a precedent, why select the exact opposite handedness for a brand new system? Given Microsoft's vicious competitiveness in the 1990s, I can't help but think that they wanted to make code portability much more difficult for software developers. Is it really a surprise that "all other graphics authoring tools adopted the right handed coordinate system standard to OpenGL"?
I think this looks really cool and interesting (esp. given that I'm looking for a home security system right now).

However, please can you make your website simpler and just have a regular scroll? The javascript scroll effect makes it really difficult for me to explore how this works and the benefits / features. I'm on ubuntu linux & chrome and using my scroll wheel is super slow and painful. The js scroll effect is taking away from letting me figure out how this works.

Subtype polymorphism + runtime (single or multiple) dispatch.

Multiple dispatch is one of the things I really miss about Common Lisp. I do like OOP, but often the most intuitive way to think about something is multiple dispatch, and trying to shove it into a single dispatch model can produce some really ugly code. I'm pretty sure that is the main reason there are so many anti-OOP zealots in the world.

Also, I didn't realize Dylan had multiple dispatch. I should take a look at it sometime.
Yeah I'd agree with you there.
Nice strawman. I certainly don't believe that.

That's good to know. And I'm not saying that you specifically do believe that... it's more that your earlier post just seems to fit into a meme that seems to be becoming more and more prevalent around here, in which everything becomes attributable to "luck". Perhaps I over-reached in lumping your post into that category. Probably I'm just overly sensitive on this topic. :-)

Environment plays a huge role, even within America. Health plays a huge role, even in America. Anyone that is successful has been very fortunate, and a lot of smart hard workers have not been fortunate. It's important to recognize that.

I mean, yeah, in a sense... but you can work backwards from any success and find ways to attribute that success to luck. I mean, we're all "lucky" that a huge asteroid didn't strike the Earth yesterday and cause a worldwide cataclysm that might have killed us all. But focusing on that isn't, IMO, terribly useful, exactly because those things are out of our control.

OTOH, unless one rejects the idea of "free will" (which is certainly a valid point of debate), then you can control your own choices and actions - and I tend to believe that it's more important to focus on those things which are subject to (at least a degree of) control by us as individuals.

I found the comparison of the iPhone to a "Star Trek" communicator a bit off topic. Even 40 years ago, I don't think anyone would have argued that something like an iPhone would be possible in the future. The idea didn't violate any known physics. Hand-held two-way radios were already commonplace. The fact that we achieved sufficient advances in circuit miniaturization and battery technology to build a hand-held smartphone does not in any way imply that we'll be able to build a warp drive for a spacecraft.
