The optical private network from CERN to the tier 1 site where I work was upgraded from 10 Gb to 40 Gb between the first and second runs of the LHC. depending on what goes on during the second run that might need to be increased again. Building high bandwidth infrastructure for use by lots of (paying!) customers is probably more viable for large corporations than it is for science, where you have a budget at the start rather than having things pay for themselves over time

The storage will need to constantly increase in that time, too.
I will take the point of view of someone who went to college. Actually I just graduated from my 5th year(I think it's master degree) and going to PhD in computer science.
To understand what I want to explain, you need to know that I began college with 3 years of biology, and then switch to computer science. It is only in my 3rd year that I realised how much I loved computer science. I worked my ass off to get directly from 3rd year of biology to 4th year of computer science, so I basically learnt everything by myself too.
In the end, I felt that every "practical" classes were pointless. I don't need someone to learn a new language, and it seems you don't either. But it is when I tried some theoretical courses that I realized how much I had to learn in this domain.

I never learnt anything about advanced algorithmic, or graph theory before, or language semantics. But in the end, by knowing all that I really look at a problem with a different point of view than before. I am able to imagine some new tricky algorithm etc.

All of that to say : It depends on what you seek going to college. You will be bored if it's just learning some new language, because you either know them already, or you will go faster than the course. But if you want to learn some more theoretical knowledge, you will learn some new stuff for sure.
Then again, I don't know where you live, and college might be quite expensive in some country, so I can't tell if it's really worth the money (since you already have some years as a developper). But it is totally worth the time imo.
Since you work there.. why did you guys choose that approach for 2fa? Reading what's written on the help page about the master password, it sounds like you want the master password to serve as a recovery code. So why not just have recovery codes instead?

Also, since you would generate the recovery codes, there wouldn't be a need to explain why the master password should be long & random; and it would reduce the risk of customers using an easy master password (either from failing to change it, or failing to use sufficient length/randomness).

[Many services w/ 2fa support recovery codes.. here's github for example: https://help.github.com/articles/downloading-your-two-factor...]

Ask HN: Can community owned marketplace/exchange/protocol exist? Are there any?
Problem:
On a daily basis, people all over the world use various marketplaces on the Internet to exchange, buy or sell different things. From jobs to houses, everything is being traded online. There are companies which are competing to create their own marketplaces, but the more I use these, the more I feel there should be a common/better way.

Current situation:
Each marketplace has its own UI, app, API, rules to go through very similar "kinds" of information. And there are yet different ones for each geography although most of the information maintains very similar properties.

Each job site or house rental site or car sharing site or others have their own format. And then we have aggregators who make their own UI, app, API...

Thus my question:
Could there not be a common standard protocol to share demands or supply information? People who want add listings contribute together to bear the cost to maintain the information storage, search, retrieval. The cost per person or company would literally be pennies, since the population is very large. It could be P2P too, I am not particularly sure how to maintain this. But I want to understand if I am the only one seeing this issue.

Options Thinking in Today’s Morphing Economy
It seems like the vast majority of collisions with google's AVs are rear-end collisions at intersections. I'm surprised that they haven't put any technology in place to attempt to avoid, or at least reduce the impact of these collisions. Clearly, predicting the trajectory of other vehicles should be second nature for the AVs.

In the video, there appears to be a shoulder with plenty of escape room.

Is there any attempt made to un-distract the driver? Flashing brake lights? Horn?

The June report from Google (http://www.google.com/selfdrivingcar/reports/) contains some interesting language:

"The Google AV had been stopped for about 11 seconds at the time of the impact"

The cynic in me thinks they are intentionally avoiding technology to address these types of accidents so that they can unequivocally prove the the AV had no fault (i.e., had been stopped for x seconds).
Cool tricks. This lead me to read about the subject of frames in python (http://farmdev.com/src/secrets/framehack/index.html).

Can anybody suggest advanced Python books to dig out more in such matters?
The grinding could probably be automated somehow; might actually be easier to get 'random' movements that way too..

I imagine a X/Y/R table with the blank (or tool, alternatively) and the tool mounted on top on a semi flexible arm that applies pressure mostly on the center, so it gets to 'rock' a little...

Put a spoon of grit on the blank, place the tool on top, press the timer and go have a beer :-)

But yeah, that's also a project that'll stick to the back of the queue for quite a while ;-)
For your eyes - I recommend installing a software that will remind you to give your eyes a bit of relax (years ago when I was on WinXP the software was called EyeCare, when I google for it now there is a plethora of projects so you will need to test what suits you best)

For productivity - what helped me a lot was to block myself on my home router from accessing all distractive web pages I used to pop in every now and then (i.e. playok.com for just one chess game, linkedin, facebook, ycombinator :-) ) - I found that my brain loves to be distracted and it is not that simple to keep focused, blocking distractors helped. Having that said I was also allowing emails in certain hours in the morning and in the evening (no emails during the day).

Also I completely cut on my favorite games (even during the weekend) like HalfLife, CS, starcraft... Was hard to make this decision but in the end appeared to be a great time saver.
The Physics of Wall Street covers the history of math from Bernoulli through Mandelbrot and how we arrived at modern algorithmic trading.

I always feel so uncomfortable about my car considering how old it is, and I know nothing about it or how it works. Everyone around me just cracks open their hoods and fixes their car, swaps tires, etc. I can't just move stuff around without actually understanding what anything is. I honestly have been wanting to learn more about cars. It also helps keep up with mechanics when they tell me things I don't fully understand, I don't imagine they want to sit around all day answering my questions, they probably have other people to work for. I only vaguely understand the things that have gone wrong with my car and the symptoms.

Thanks for such a beautiful website, and for everyone else sharing some interesting links. Being computer savvy is not entirely helpful when it comes to the mysteries of cars (not entirely anyway).

Btw I would love for there to be an Android app if possible. :)
The authorities have a tendency of being creative with numbers. It could mean anything really. Maybe they received 215k GET requests.
It depends - the amounts of data involved are mammoth by today's standards, but the idea is that we will develop new methods and tools to make the project feasible. The announcement and funding of the SKA will probably help this process along too, as specific challenges are addressed throughout the programme

One of the problems with the DRIP bill was that because normal parliamentary process was not followed the press and public did not have time to get into the meat of the bill prior to it being passed. With for example the snoopers charter (version 1.0) there was time for the implications to be discussed in public.

There's been quite a few hurd articles lately. I wonder what the interest is?

Maybe focusing on only the drivers needed to make it run well in VMware or openbox would improve the usability story. I've always thought it was interesting, but a lot of people wrote it off after linux took off. I can't help but think that hardware performance has improved to the point that the supposed perf penalties of microkernels wouldn't matter.

Hey Ryan!

This is an awesome tool, I'd love to use this on my workflow. But right now I'm not sure I can use it, a "normal" user today is into more than one Slack and surely has a lot more than one website on his GA account.

Do you plan to develop a way for your users to choose which Slack they want to post to and which website they want stats from?

From the article:

There will be far too much data for it all to be simply recorded.
The plan is to "use an algorithm to reduce that data down to a
smaller magnitude that you can then process further on a super

This is exactly what I have found myself going through since making an attempt to switch to 3d video game development. Specifically with the game I'm currently building and some other things I've wanted to get involved with (I've taken an interest in AI lately... like everyone else). I can see how having more math in my past would help greatly.

That said I've been studying algorithms and supplementing my math with books from the library. I also have a list of bookmarks to various CS courses. I just need to block out time and watch them.
But you'll get maliciously prosecuted for guessing a sequential URL and typing it into your address bar thanks to CFAA...

Well, no. It's a bit more complex than that.
That's not the same thing at all. The benefits of a destructive pursuit don't make it a more attractive thing to do. They're in opposition to the negatives of the original action. The side effects of a constructive pursuit do make it a more attractive thing to do because they are in addition to the already positive result of the original action.
I actually am an alumni, though I left before the end. I'd characterize your gut as accurate.

Loosecubes was the first VC-backed started I ever worked at. And it taught me a lesson (Lots of lessons, actually! Fantastic experience with amazing people.) that I would then be taught at a few other startups as well: When you take that money, you need to be prepared to return it 100 times over. That's why they are investing in you. Not to get it back with a 10% return but to get it back 10x or 100x.

After more than a year of co-working, I had this idea, too. I don't know if it is like that everywhere, but it is hard to connect with people - they are just focusing on work, and often aren't very talkative. Which I find very weird.

I'm very curious how this works out.
one wonders what horrendous blackmail GCHQ have over the politicians that support them. we arent governed by these puppets, we are governed by 'the market' and large corporations. every political party is 'the business party' - we should have let the banks collapse when they were going to. and all this is why im packing up, selling everything and leaving the UK forever! fuck these bastards who fucked my country up.
It's one of those cases where condensed matter physicists study a system which satisfies equations known from (more) fundamental theories. Other recurring examples are "black holes" in the lab [1] and "AdS/CFT" (of string theory fame) in solid state and quark-gluon plasma physics [2].

That aside, there is a mathematically well-defined sense in which Weyl fermions are the most "fundamental" fermions: the other kinds you hear about, Dirac and Majorana, can all be written as combinations of Weyl fermions. To make a Dirac, you take two Weyls of opposite helicity and couple them with a common mass term. To make a Majorana, you impose an additional algebraic condition on the two Weyls (take the complex conjugate of Weyl #2, reshuffle it a bit, and you get Weyl #1).

The most significant thing here is the mass term. When you look at the equations, it's immediately obvious that what the mass term does is mix the two Weyls in a Dirac: even if you prepare a pure state of one Weyl, as soon as you set the clock ticking, the mass term will turn it into a mix of two Weyls... unless the mass is exactly 0.

So a less mystifying way to describe the achievement of "making Weyl fermions" is simply "making massless fermions".

Kind of funny that it resembles old diesel injectors. There's a piston fuel pump for each combustion cylinder. The stroke is constant but if you don't need the full volume, you just let some of the flow go back.

Nowadays diesels don't use that anymore, they've moved to a very high pressure common rail and electronic valves.

Well, we do have eavesdropping laws. You can record and publish a conversation as long as one party is aware of the recording. You need a wiretap warrant if you're a third party listening in. I don't think the same applies to photo/video, but I'm not sure how it differs if it does.
Hey guys,
I've been a lurker of HN for a while and thought I'd post up a Show HN thread for my new Android/Web app geared towards tracking body measurements rather than body weight.

This is a super early release so there are bound to be issues (see: http://genius.com/4126912/Genius-the-genius-isms/Take-the-ro...).

Really interested in getting some early feedback, so your comments are very much appreciated.

The plan is to focus on next implementing goal tracking and then to add some simple social elements (a la Instagram).

Cheers!

While we're here, the article you linked recommends equality comparison w.r.t. "the maximum number of possible floating-point values between the two values".

Any idea on how to go about this in JavaScript? The binary representation of the float isn't as easy to come by (compared to C, for example), but I wonder if you couldn't get a decent approximation with Math.log2.
Maybe I made more than one mistake in my description (I definitely made one: the third "a" in "banana" is of course a schwa, not the vowel in "arm") -- but the "a"s I put in "Banach" are (modulo incompetence) pretty much exactly the ones you'll find by clicking the "listen" link after Banach's name at the start of his Wikipedia page. So I'm not sure what you mean about "a foreign import that actually asks for it". And I just checked the etymology of "banana", and the likely Wolof original has exactly one /ɑː/ in it, in the same place as I put one. But, see above, I misdescribed how I say "banana" so I may have caused confusion.

This comes at the right time, as the Tories are also trying to pass much worse surveillance legislation where they want to bypass the judges and only have the Home Secretary sign the "warrants" for mass surveillance (so even worse than the rubber-stamping secret FISA Court in the US).

This ruling specifically says that it's illegal because the investigations aren't vetted by judges or independent third party bodies, among other reasons.

Reading email sent by a human requires NLP features that I don't see in this example. Sure, headers have clear meanings and delimiters, but bodies are pure speech. Don't be fooled by the fact that they arrive as strings:

"Hey I saw you had a table for sale, I need one. I can give you like $30 for it and a puppy." <= in which the sender has sent mail to a list instead of a person and does not have a table for sale, even though it matches the regexp and provides a parseable price.

"The table is A QueeN Anne style repro abouT $0 years old, I think five hundred is a fair price but we can haggle." <= in which the seller holds down a shift key a little too early and the program will register a price of free rather than $500.

You've heard that it isn't a good idea to parse HTML with regexps? Natural human languages are worse.

https://en.wikipedia.org/wiki/Utility

>"The St. Petersburg paradox was first proposed by Nicholas Bernoulli in
1713 and solved by Daniel Bernoulli in 1738. D. Bernoulli argued that
the paradox could be resolved if decision-makers displayed risk aversion
and argued for a logarithmic cardinal utility function. The first
important use of the expected utility theory was that of John von
Neumann and Oskar Morgenstern, who used the assumption of expected
utility maximization in their formulation of game theory."
