I'm no physicist, so I am just guessing.

It could be some phenomenon similar to what we see in emission spectrums, where a pure source can emit photons at multiple precise energy levels. except that in the case of particles with mass(apparently neutrinos have a mass) this would result in a difference in speed. Not a big enough difference to be noticed on 700 km , but enough to make a 4 yr difference on 170kly.

Of course this is still wild speculation without much background.
Depends on who you mean by 'anyone except someone I explicitly want to share it with'. You will most likely be able to decide which fb users have access to it, but it will nevertheless be accessible (albeit in some condensed form) to advertisers.

My strategy: Have a bare minimum of servers (darn things are ridiculously cheap anyway) hosted somewhere reliable near where I live. Any NEW stuff goes into the cloud. So if I decide I need to service European customers I might rent an EC2 VM in Dublin,Ireland from Amazon and test it out. If that does well I may buy physical servers depending on economics. Any burst traffic would also be handled by virtual servers.

If you do the math, CPU in the cloud is just not cheap. Storage in the cloud may seem cheap, but that's only because enterprise storage is so expensive relatively speaking. If you're willing to put some time into it you can get 80-90% of "enterprise" functionality from your cheapo storage as well,thereby beating Amazon's economics.

But cloud is easy to provision and good for folks that don't want to deal with operating systems, networking, security, grumpy middle-aged sysadmins (that'd be me) etc etc.
This is a really important distinction; I see a lot of people claim they don't understand something because implementation is hard. Sometimes implementation is just hard. They should note this more often in schools rather than taking an extreme position of self-esteem/whatever.

I've heard good things about New Relic for performance testing.

MiniTest, which is built into ruby 1.9 has a full suite including performance tests. It's really cool because you can measure e.g. whether an algorithm scales linearly or not.
Should I Invest In Silver – Where’s The Smart Money Moving
I'm not an economist by any accounts, but this statement troubles me:

"The New York City experiment was designed to last three years, and the families participating knew that. In other words, the program inadvertently replicated some of the very instability it was designed to overcome. "

3 years of financial assistance, while not a long time, is hardly unstable. It's certainly enough time to make a lot of headway towards life when the program is up. The article makes the case that CCT programs simply didn't work because they didn't last forever. I'm not sure I buy that line of reasoning.
I know you were being a bit sarcastic with the history comment, but you can add things to the timeline. So theoretically you could go back add pictures from way before facebook's launch.
Meg Whitman Named CEO of HP

So, this board has recently brought in a software guy who doesn't seem a good fit for a company that does a lot of hardware, had him make a bunch of unpopular decisions, then quickly replaced him with somebody that's been on the board for quite some time, without reversing any of the previous "damage" that Apotheker is being blamed for.

Apotheker appears to be the fall guy for some unpopular decisions that the board wanted made anyway.
Ah, been a while since we had such an entertaining high profile trainwreck in progress to watch. What the hell is the board thinking?
Are they concerned with the possibility of data falsification?

This has happened in other fields.
Well, if you guess enough times...
Shoot me a message. brandon@brandoncordell.com

I have strong PHP experience (currently building enterprise level PHP apps) and I've done extensive payment gateway integration, including custom e-commerce platforms.

Very interested.
I think what happened was that the reference was passed to a function that (1) under most conditions (I think there was a fast-path added after the function had been around a while) accessed it directly, and (2) under all conditions turned it back into a pointer for another call. The way that function was called in this particular case was outside of those "most conditions", so the only thing that was done with the invalid reference was to turn it back into a pointer and then null-check it. And so while making the reference probably counts as "dereferencing" the pointer as far as language rules go, the memory that it pointed to was never actually accessed.

(Why yes, that does sound like something badly in need of refactoring. And illegal reliance on implementation details.)
A response to Joe Hewitt's "Web Technologies need an Owner"
Assuming you're talking about entanglement (an effect of quantum mechanics), then no. Since QM describes the behaviour of particles (such as the 'faster than light' neutrinos in this experiment), you can't use the behaviour of particles to describe QM.
Coroutines are more like reading multiple books, leaving bookmarks behind and returning to them as needed. I think of caching like moving the resources you're working with to be near at hand so it takes less time to get to them.

(When you're painting, for example, you keep pencil, eraser, brush, paints, and palette nearby, because they're in active use and it would take awhile to fetch them every time you needed them.)

Your other examples are great though. I worked in a kitchen for a couple of years and it's definitely all about concurrency.
There is a special place in hell for you.

Had me laughing though :)
You can read on various massively scalable webapps architecture. http://highscalability.com/ seems to aggregate those, and you can find articles and slides published by the developers of more services if you do some googling.

The key to speed and load tolerance is massive multilevel caching; every service does caching differently but they all do.
Meh. Steve Jobs wannabe.
Neutrinos released in type II supernova explosions are thermal, so they should have a broad spectrum unless pretty much everything we think we know about SNe is wrong.
I currently live ~1500 miles away from most of my closest friends. That's one good reason.

I also travel frequently for work, and I like the idea of remotely listening to and chatting about music with my daughter, since it's something she might actually dig doing with me.

All that being said, I can't see this being an everyday activity.
But why? Why are you so hesitant? Are you starting a website for battered women, a support group ex-Christian-fundamentalists, or a web-app to help Yakuza members leave their organizations?

And if your name is on everything, including DNS records, won't it be fairly trivial for someone to find out who you are?
I don't think the claimed potential result is that neutrinos always travel exactly 0.0025% faster than c, but that they can - perhaps under very specific and special circumstances. I agree with your skepticism and think we should approach this slowly, but your I don't think that your particular example disproves or contradicts the claim.
I'm not sure what you are saying. Sending a message in Objective-C just compiles down to a C function. Syntax has absolutely zero to do with the language choice or transition to another language. It sounds like you think adopting another language means you tack some different syntax on top of Objective-C and call it a day. This is incorrect.

Furthermore, when I hear a programmer make disparaging remarks about a language because of its syntax (or really any reason), I immediately know not to hire this person or trust any of their opinions; an experienced, rockstar programmer would never even hint at this sort of sentiment.
Time to accept bets on what the next screw-up will be.
Think of the wagon wheels, as seen in a western movie, turning back, or moving at bizarre speeds in either direction. It's not a perfect analogy, but it's a related phenomenon.

How To Enable Facebook Timeline Right This Second
I spent hours trying to help a friend in college "get" enough assembly language to not fail a class. I had already done assembly language development professionally and had previously gotten an A+ in the class, so I understood the concepts well, and I explained them from a dozen different directions.

I don't care what the OP says. This guy was simply not capable of understanding the concepts. Maybe at some level he was, and he had some kind of psychological blinders on that prevented him from getting what I was saying, but he really, really didn't get even the most basic concepts. And when it comes down to it, it doesn't matter whether he has some innate ability that he can't tap -- if he can't do it, even with lots of help, then he can't do it.

While I was helping him, others from the lab came over repeatedly to ask me for help, assuming I was the lab assistant. I WAS able to help a half dozen other students understand their program.

It was his third attempt at taking the class. He finally gave up and changed his major, IIRC.
I'm just citing personal experience. I would be very interested to see studies that clearly backed up or refuted my perceptions. The real machinery at work is probably more interesting than I imagine, and definitely more interesting than I make it out to be in the article.
I think they are just going after something people really don't want. People don't want to see what their friends are doing because chances are its nothing. This appeals to 5% (the scobles) of the social world. They aren't solving a problem that sally facebook has.

Oh Yes: In the 17th century Sir Issac Newton declared that light was corpuscular, that is, made of particles. Though there were some outstanding questions, this view was accepted for over 100 years. Then in 1803 Thomas Young proved that light produced an interference pattern after it passed through a narrow slit. Such an interference pattern is a distinctive indicator of a wave. His experiment, along with subsequent work by Fresnel, soon persuaded scientists that light must be a wave. In the 1860's James Clerk Maxwell produced some brilliant mathematics, today known as Maxwell's equations, and proved that electricity and magnetism were integrally related as one phenomenon. As a byproduct, his equations showed that there should exist a certain kind of wave, consisting of a special interlocked pattern of oscillating electric and magnetic waves, an electromagnetic wave. Based on other empirically known constants associated with electricity and magnetism, his equations yielded a calculated value for the speed of this electromagnetic wave. The speed was exactly the same as the velocity of light that had been calculated by other experiments. This remarkable discovery demonstrated that not only were electrify and magnetism one phenomena, but light, a phenomena seemingly quite unrelated, was also an aspect of the same electromagnetic phenomena. After these developments, and for a some time thereafter, scientists understandably had thorough confidence that light was indeed a wave.

Against the background of this solid conclusion of science, Blavatsky, writing in 1888 in the Secret Doctrine (volume I of the Secret Doctrine, called "Science and the Secret Doctrine Contrasted), gave her readers an intimation of the future when she hinted with a question.

True, the corpuscular theory of old is rejected, and the undulatory theory has taken its place. But the question is, whether the latter is so firmly established as not to be liable to be dethroned as was its predecessor? THIS HAS BEGAN!!
From my understanding, the timeline will feature your most recent activity and then summarize the rest of it. Therefore you only really drill down on the people you're interested in learning more about anyway. If it's just a random coworker, you'll focus on the above-the-fold recent activity.

It really makes sense to me... When you get down to the "show more" link at the end of a friend's profile what you really want is a summary of the important stuff beyond that. It actually reminds me of when you got the bottom of your feed on friendfeed and were presented with a "best of day" link.

Front End Developer
Description:

We are currently looking for an energetic and experienced front-end developer. You’ll be working with a world class team on a product that is renowned for putting usability first. You take pride in clean client markup, re-usable design elements and understand that the real world consists of a plethora of browsers and “standards” (i.e. test, test and test). You can multi-task and prioritize.

Requirements:

* 3+ years experience with (handcoded) HTML, CSS, JS
* Strong knowledge of Ruby, JavaScript including object-oriented JavaScript, DOM scripting, and AJAX.
* Ability to implement client-side libraries/frameworks such as Prototype and JQuery.
* Knowing your way around Rails views and Git is a big plus.

Please contact bishimckeand@gmail.com
I'm not an expert, but this is what I've cobbled together as a fellow Ruby/Rails startup person.

Fault Tolerance: Just use Heroku. We've seen maybe an hour of downtime in a few months?

Speed (and fault tolerance): Cache everything you can, assets on S3/CF.

Testing: Rails Test Prescriptions by Noel Rappin
[http://pragprog.com/book/nrtest/rails-test-prescriptions]. Then you can choose what you like, but I like Test::Unit, Mocha, FactoryGirl.

Code Abstraction: Rails is already pretty sensibly organized, and if MVC + tests + static assets is not a good fit for your webapp, you really should not be using it in the first place. One minor point: Noel and others will tell you to use skinny controllers.

Curious what other people consider best practice for Ruby/Rails startups.
The influx of posts about "how to scale" is noticeable. Are more startups having this need? Or are more of them prematurely optimizing?
Experimental error seems likely to me once again. 10ns at c is 3 meters, over 730km + uncertainty in time of particle generation and decay + detector uncertainty...I don't buy it.
From the project site: http://operaweb.lngs.infn.it/spip.php?rubrique41

OPERA needs an intense and energetic beam of muon neutrinos traveling a distance of hundreds of kilometers to seek for the appearance of oscillated tau neutrinos. A beam of this type is generated from collisions of accelerated protons with a graphite target after focussing the particles produced (pions and kaons in particular) in the desired direction. The products of their decays, muons and neutrinos, continue to travel in generally the same direction as the parent particle. Muon neutrinos produced in this way at CERN cross the earth crust reaching OPERA after a 732 km journey.

Sure many people will spend time curating their timeline, but I think that for most people an algorithm will just select the best stuff.

Many it seems. And the penis slaying dragon.

"Does this add value to the discussion?"

Nope.
I wonder how accurate their time measurements are. If nothing can exceed the speed of light, what makes them think they can rig together hardware that will accurately measure speed at that magnitude?
It's funny- I remember everyone saying that Facebook was victorious over MySpace because it didn't allow people to customise their profiles and put irritating music players on them.

Now, Facebook has a customisable header (effectively) and integrated music playing. I'm not trying to suggest that the implementation is the same as MySpace's, but it's funny how these concepts come back around again in time.

That's actually an issue I worry about. Sort of like how everyone's plumber is the best. I could be wrong but there's no good way to tell if a sysadmin is good. The sysadmins I know are the types where, if they're doing their job properly, you don't even know they are there or anything happened.
Totally agree. It lacks of basic features, modularity, extensibility, a proper community, and therefore support and external resources such as themes and plugins. Requires so weird technologies that finding and maintaining a suitable hosting for it is hard and expensive. There is absolutely no reason to use it.

Oh, wait...
Facebook Open Graph Protocol
This was the first time in awhile I got that "evil empire" vibe from something. Not to say that what Facebook is doing is inherently evil, but something about cataloging life into such a precise order seems...strange. From a technical standpoint, however, what Facebook has achieved is quite impressive. The design is gorgeous as is the interaction (and that's speaking without having actually used it). This definitely marks an exciting and encouraging time to be in this industry, but I hope it doesn't mean that we'll be living life via the timeline.
It's what Path is trying to capture, but they're such a new service that they don't have the problem of displaying multiple year's worth of data (in their case photos). If people keep using the service, I'm sure they will eventually have to come up with a better way to find the most interesting moments.

Assange is not, as far as I know, in favour of widespread breaches of privacy. He is in favour of breaching the privacy of governments and non-state organisations, etc for the public benefit.

Assange spent a large amount of his life (before wikileaks) working on technology that enables individuals to maintain their privacy and protect their personal information. It's important to understand that wanting to control his own autobiography is not a contradiction with respect to his work on government and corporate leaking.

I applied for Y-Combinator about a week ago, and I keep obsessively rereading my application because I'm not sure how to make myself stand out.

I'm really struggling with how to say everything about who we are as a team, and how to give our business justice in so few words. If anyone has applied before or has any sort of tips I would love to hear from you. I know we could be successful and that Y-Combinator would be great for us, I'm just worried that we are one of those companies that falls into that gray area where they just aren't sure of that's described in the "How to apply successfully" guide.

Again, any sort of general tips would be appreciated. Thanks.
