I'm in a well regarded sociology department and there's a huge gap between the sociologists who take technical things seriously (programming, stats) and those who don't. People have actually rolled their eyes in classes when we read papers about simulations. I was lucky: we have a core group of students who program and gather data using modern tools, but I gather this is rare both within my discipline and without.
Eeeh, that looks awfully cramped. Especially for anyone a little overweight.
Here's my problem with the idea that you'll always get the best candidates from referrals:

You're the hiring manager. I'm a professional programmer who works with you. Let's say I personally know and can vouch for the ability of 100 programmers. There are 7 billion people on the planet. What's more likely? That your best candidate will come from my 100-person address book, or that it will be one of the other 6,999,999,900 people in the world you're not looking at?

Now it is likely that someone from my address book will be, on average, a better candidate than a random selection from the rest of the world, but all that shows is that professional references will produce "above average" candidates.

EDIT:
I suppose the difference is whether you want the "best way to find good people," what the parent said, or a "good way to find the best people" which I argue referrals might not be.

I think a "profit sharing" system for a restaurant would be pretty complicated. Plus tipping to me is somewhat like a price discrimination system. Cheap skates don't tip or pay the minimum, people that can afford tip more, drunks tip the most. So the same service is being provided at different prices. If you throw that out the window, you might never get those dollars back.
Same. Can someone explain the context/significance of this?
Traditional trains have wheels and engines, which are quite heavy. And with a traditional train you're trying to minimize losses due to air resistance, which is not an issue in a low pressure tunnel.
The Tokaido shinkansen serves commuters in a very dense area. Also, Tokyo to Nagoya will run you a hundred bucks last time I rode.

Why would anyone want to live in LA and commute to SF, or vice versa? Even if ticket prices are low, property prices on both sides are very high. It would make much more sense to build a hyperloop to nowhere economically, and turn that area into a bedroom community.
From the pictures, 1.10m heigth with 1.35m width looks more right; in any case, there's no simple typo:

If the feet are correct, (6.11 ft), then it should be 1.86m, not 1.10m (or 2.10m as you suggest.)

If the meters are correct (1.10m), it should be 3.61 ft (not 6.11 ft).
You'd still have to pour the foundation in place though, right? Or can you make foundations off-site and then drive them into the ground?
Can anyone explain this like I'm 5? I'm really not following what's going on here.
I'm one of the co-founder. We're in Belgium, Brussels.

Basically, we are building a platform for the nightlife.

The global idea is to provide a fast, easy, reliable, honest, accessible website to find parties in your city.

Accessible in multiple languages and devices, without mandatory login to find a party.

We're using the most complete and up-to-date source of information for parties (Facebook) and make them available in a clear and easy manner.

We provide multiple tools for nightclubs and events promoters. Analytics, viral promotion tools (http://bit.ly/1eFm7A9), customization,... And we're working on a ticketing solution dedicated to nightclubs.

Our bet is local clubbing guides aren't reliable because of their financial dependance on events promoters. Our premium features for nightclubs are paying, but at a very low price. (even free when possible) to avoid to become dependent of them.

Our business model is to sell nightlife oriented tools and presence on our platform to brands. (white labeling, contests, "spot" events,...)

Our MVP is released since june and we're looking for feedbacks.

Thanks for your help!
I'm not so sure it's a side-issue, in that the northeast corridor train routes don't just allow people in, say, NY to go to Washington, but also people in Philadelphia and Baltimore to go there as well, since those cities are on the Acela route.

And, if your city is not on the Acela route, you may well be able, due to the area's density, to take a commuter rail or another train to get to a city that is on the Acela route.

Similarly for Acela's Boston-NY route -- New Haven is on the route, so people from Connecticut can likely get to it.

And, of course, people in NJ can easily pop into NYC and grab Acela as well.

By contrast, the lack of density in CA would mean that aside from LA - SF (and a bit of traffic to and from Sacramento), you wouldn't likely have that sort of potential passenger-base.
I studied marketing (with an emphasis on e-commerce) at Uni. In a professional capacity I've put together and executed campaigns for various online and offline businesses.

Tl;dr - Start by mimicking your competitors (or the next best thing), test whatever you do, and document whatever you do. If you're looking for a book I'd check out Steve Blank's "The Four Steps to the Epiphany," which contains useful worksheets, including one to develop channel strategy and pricing model. You can preview the first few chapters of this book for free at Stanford's website [1]. An aside: Blank also published a sequel to this book called, "The Startup Owner's Manual," which I haven't read, but which I've heard includes updated and electronic versions of the worksheets [2].

Marketing is similar to engineering in the sense that you need well-honed problem solving skills if you want to drive predictable and repeatable results. The process by which you achieve these results will vary depending upon your product, your competitors (if you have competitors -- or substitutes or compliments, if you don't), your target market, your industry (or industry segment), the economic climate, the tools at your disposal, among other things.

More concretely here are a few things I like to keep in mind when planning and executing a campaign:

1. Quoting Stravinsky, "Lesser artists borrow; great artists steal."

If you're not first to market study your competitors. Become their customer. Find out how they market to their customers. Hypothesize what might [be|not be] working for them. Mimic what you think might work.

If you /are/ first to market use the above approach to study complimentary products or services, or substitutes.

2. Always be testing

Once you've found a promising idea, test it. Ideally tests would achieve statistical significance, but this is not always possible. Furthermore, commit yourself to multiple tests (e.g. A/B tests, multivariate tests), but don't be afraid to trust your gut if something is obviously [working|not working].

Use whatever analytics tools are appropriate for the job and create reports for yourself based on these data (e.g. Google AdWords, Optimizely, etc.). See below for more on the latter half of this point.

3. Keep data organized

Have a written plan when you begin. And think of marketing your product like you would the code base for a well-written and long-lasting program. Comment your steps along the way so your "future self" will know exactly how you achieved certain results. (Note: documenting what didn't work can be as important as documenting what did (think of a bug tracker as an analogy).)

In essence, your marketing documentation and data should serve as a compendium of what worked and didn't work so you can build on successes and prevent unnecessary mistakes. And like code comments it can help bring someone else up to speed if your product is successful and you add to the team.

I'm still really sad that the Etoile OS project died out. (http://etoileos.com/etoile/) Maybe it can start up again if GNUStep catches up to 10.6.
The lack of fine-grained permissions per app is Android's fault, not Facebook's (not that they aren't benefiting).

Android application manifests means that if even just one user of your app might want to use a feature that requires elevated permissions, your entire app must be given these permissions for all users at installation time.

Which is obviously a huge security issue. What if I want to use the Facebook app but deny it permission to my address book? Not possible out of the box.

E.g. There's a feature to see if any of your phone contacts already have Facebook accounts. To service the potential people that wants this feature to work so they can easily "friend" these people on Facebook, the app must have this permission for everyone who installs it.
I would gleefully slap another $50-100 onto every plane ticket I ever bought to ensure that there was nobody anywhere on the plane under the age of 16. I can't be the only one...
I'm not lazy. I'm time poor. I would love to have time to learn how to code but I don't. That's why tools like Macaw and others are a great asset to me.

I see tools like Macaw actually being the death of front end development. To me its a waste of time going from Photoshop to code.

Designing in the browser and exporting the code removes the need for front end development.

Sure it might be rough and dirty now but its early days.
JSON makes me think of the Argonauts. They should probably change the name to something like "Language-agnostic hash-based data interchange format" or something.

In all seriousness, if you're familiar with protobuf the name seems reasonable enough. If you aren't, I guess you're not entirely the target audience.
We really do have arguably the best freight rail system in the world. http://business.time.com/2012/07/09/us-freight-railroads/
My first thought was also reflected in the comments section... You could easily rewrite the headline as 'Near-death experiences indicated by surge of brain activity'.
Those are just signatures, what is going on inside the boxes?

Also, how does one encode iterative computation, like a data-flow analysis, in Haskell? And symbol tables? Is it sufficient that the symbol table is encapsulated within compile even if it involves dictionary read/writes? I'm genuinely curious.
I'd just like to plug the Dictionary of Numbers chrome extension at this point which provides context for all of the numbers in this thread. For example, did you know that $14 billion [≈ net worth of Steve Ballmer, CEO of Microsoft]?
Depending on your industry and location, recognition doesn't always come easy. Considering that a majority of employers will have a non-technical HR employee only makes things worse. I think that there is definitely a spot in the market for a company that can successfully break this barrier and improve the marketability and recognition of job seekers. The key is that a service like this isn't the be-all and end-all, but instead should serve as a supplemental indicator of a candidate's ability.
Because there's something inherently useless about it, or because you personally don't care about the NeXTStep/Cocoa APIs? If it's the second, then it's totally irrelevant to the discussion.

The point of this is:

1) to have a working Cocoa port on Unix, Linux and Windows platforms.

2) to provide a way for programmers creating ObjC/Cocoa apps (and with iOS and the Mac App Store those are hundrends of thousands) to port their apps to Linux/Windows.

3) To move the GnuStep project forward.

4) To provide an additional set of nice, modern APIs on Linux. E.g. GTK3 is nowhere as good or feature complete as Cocoa (even 10.6 Cocoa).

5) To eventually give the possibility for cross-platform development of Mac/iOS apps (e.g games).

You're not supposed to be able to embed messages inside of bitcoin transactions. But this person who claims to be Satoshi did just that. He/she/them embedded a git commit that fixes a bug in the Electrum server. This bug is perhaps what allowed the non-standard transaction to slip through.

Hope this helps.
That would be great, all you need is 1 country somewhere in the world to prove viable and it becomes a much safer political prospect elsewhere.

Only one question -- can you take this on a plane?

A while ago I had a cell phone where the battery charging circuitry went out. The battery was 3.6v, so I hooked up (via Velcro) a AAA battery holder and used rechargable NiMH batteries. However I was told (when I called the airline I was traveling) that it most likely wouldn't make it past TSA.
What is the estimated man-hours required to complete this project?
I was thinking utilities in terms of electricity, gas, water or sewer.
Exactly, my experience with regional rail commuting in Philly was the same. Regional rails frequently have the sort of trip lengths that we are talking about here, and I have never seen a regional train that has facilities.

No. So take it with a big grain of salt.
Looks like a good idea, but the major glaring technical point that seems to be missing is the issue of horizontal stability within the tube.

When you get very low friction, high speed and no tracks, you're going to start having attitude problems without the right control surfaces available. Don't want to be spinning passengers around the roof of that tunnel!
A speech is literally the exception to this rule.

Keep in mind that GP's advice isn't aimed towards well-practiced speechwriters and eloquent speechmakers. It's to people who are nervous even about joining Toastmasters.
I think this would be much like disabling jobs for (or heavily taxing) rich people. When you reach the top, it is much easier to continue ascending, just the same as a larger lion has an easier time finding a mate, and gets fed first.

C'est la vie
> I would image the tubes will be joined with automated friction stir welding or something similiar, but that will still require a fair amount of post weld machining which has its own pitfalls

The document mentions standard orbital seam wlelding, plus specialized machining equipment that travels along the tube to smooth out the gliding surface.

The capsules are only 60% the diameter of the tube, or 36% it's area (68/47% for the vehicle-carrying version), it doesn't seem to require tight tolerances for operation. I got the idea that tube distortion and movement is taken into account into the system.
Here's an idea that has been on my list for years that is doable in a short time but I just haven't gotten around to it:

Build a URL shortener for directions to physical addresses. Huh?

1) get a domain, say http://right.to (I'll give that to you if you build this)

2) Users can register a nickname and location:

daves_house

123 Main St, City CA, 90210

3) When someone requests http://right.to/daves_house the page uses HTML5 to get the requestor's location and responds with a map with a route (and turn by turn directions if you wish) from where the requestor is at that moment, to the address that is registered. The directions come from Google or Bing maps or any other open directions API that your back-end fetches.

The value is that I (your customer) will have a URL that I can always give to people for directions to my house or business no matter where they are.

Bonus points: A phone app that sends SMS or email messages containing the URL http://right.to/p/xxxxx.yyyyy where xxxxx and yyyyy are not previously registered nicknames but rather encoded lat/long of the sender. Huh?

1) I launch the app on my phone. It gets my GPS coordinates and creates the encoded xxxxx, yyyyy. It opens my SMS interface with a pre-populated message: "I'm right here: http://right.co/p/xxxxx.yyyyy"

2) I enter the recipients for the text and hit send.

3) Each recipient, when they click on the link, gets located through their browser and shown directions from wherever they are, to wherever I am.

value: With a few clicks I just sent a bunch of people directions from them to me without knowing where I am, or where they are. Or maybe I tweeted that. Every viewer gets a custom route right to me.

This idea was inspired by https://news.ycombinator.com/item?id=2093261 wherein I discovered that an app I wanted to build already existed, so I tweaked it a little (directions instead of just locations).

Let's say you've serialized a tree structure of versioned data as JSON. Branches are arrays and leaves are objects.

data OTree = Obj Object | Node (Data.Vector.Vector OTree)

instance FromJSON OTree where
parseJSON (Array as) = Node <$> traverse parseJSON as
parseJSON (Object o) = return (Obj o)
parseJSON _ = fail "OTrees are objects and arrays"

instance ToJSON OTree where
toJSON (Node as) = Array (fmap toJSON as)
toJSON (Obj o) = Object o

Now some of these objects have keyed "version"s which are arrays of semantic versioning numbers. Write a function which decodes and re-encodes a new tree with each of these semantic versioning numbers incremented at the patch level. If the version isn't in that format, just ignore it.

In Haskell you'd want to write a generic traversal over the objects of the tree useful whenever you want even access to the contained elements.

eachObj :: Traversal' OTree Object
eachObj inj (Obj o ) = Obj <$> inj o
eachObj inj (Node as) = Node <$> traverse (eachObj inj) as

And then here's the finale, the actual lens code specific to the task.

upgrade = _JSON . eachObj . ix "version" . _Array . ix 2 . _Number +~ 1
> Does it destroy the utility of a crypto currency for exchanges and processors to be required to detect e.g. money laundering?

It introduces a mandatory third party (the government) to transactions where only two parties are intended.

Such a virtual currency could be designed, and I don't believe it would be successful.

The Bitcoin protocol allows two parties to transact without any outside interference. If governments can restrict using a protocol remains to be seen.
Bitcoin Transaction
I don't "insist on assuming the US government is going to abuse all of the power it has", and I haven't stated that "the US is absolutely and irrevocably corrupt" - so there's your hyperbole. I suggested that in the government, as in any political organizations, scopes tend to expand. I've pointed out several examples of this, including an example in the very issue we're discussing. You also equated this with "convicting the government of thought crimes" - and I still have no idea how you made that hyperbolic connection. You're obviously incredibly upset about this so let's just drop it. It doesn't even seem like we're speaking the same language because I have no idea where you're getting these ideas about what I've said.
There are iOS mods (jailbroken) which currently enable keyboard commands and mouse use for the iPad right now. Multitasking is a big weakness that other tablet OS's are addressing or moving in the direction to address.

Let's hypothesize a 25" tablet, suspended from a monitor arm, with support for keyboard commands, mouse, and multitasking. That is effectively a desktop. The downside is processing power, which I am assuming will continue on an exponential upward trend in addition to seeing CPU intensive processing offloaded to remote servers (compiling, rendering 3D images, converting video, stuff that already is often done remotely today.) The part of this vision I find hardest to believe is a 25" tablet, so I assume it will have to wait for an advance in display tech leading to lightweight/fold-able/roll-able/etc.

Sure, Apple is going in one direction today, but if iOS falls too far behind the feature/usability curve their tablet dominance will fall.
I honestly doubt the higher cost projections would change the vote -- when talking about that much money, most voters -- myself included -- can't really discern the impact of the difference between $10 billion and $70 billion.

The only hope would be that the anti-rail side could point to the growth of projections as either incompetence or out of control budgeting, which could both sway the vote. But I think if you go back to 2008 and say, "This will cost $100 billion," the vote would be the same.
"the department says it wants to make sure Bitcoin company customers’ funds are “safe and sound,” expressing concern about consumer complaints “about how quickly virtual currency transactions are processed.”"

So, are they saying there are complaints that the transactions are processed too quickly? Because I've never had a BitCoin transaction take more than an hour or so to complete where as my regular bank routinely takes about 3 business days. Makes you wonder what their motivations are.
But regardless, it's still an interesting transaction.

>> I'm kind of shocked there hasn't been a horrified response from HN Haskell fans.

"What an ignorant fool?! How could he abandon the holy grail of Haskell?!" -- like that? :)

For someone who wrote a lot of compiler and program analysis code in Haskell I can hardly imagine myself writing the same in C++. That said, I can totally understand the author's perspective. As the author writes, "I really wanted to like Haskell. [...] But when it comes down to it, I am an object-oriented programmer, and Haskell is not an object-oriented language." And I think that's the core of his troubles. I can imagine it's hard to write Haskell with an OOP mindset and expect it to be easy. I'm not saying pure functional programming is superior to imperative object-oriented programming -- they are just different and require different mindsets. Before I learned Haskell in the university the only language I had done any substantial amount of programming in was C++. And I had to make quite a switch in how I think of algorithms. I remember a lot of my classmates struggled with writing even the simplest programs in Haskell. But after some time I've really started understanding the Haskell way of thinking and, to me, it's easier to program in this language than in C++ which I regard as unnecessarily verbose and baroque.

Personally, I wouldn't even think about writing a compiler in C++ unless I was feeling masochistic. That said, I have never written a compiler in C++. So, should my experience in writing compilers in C++ have been greater and my experience with Haskell lower, it would have made sense for me to use the tool I knew how to use best (C++). Since I don't know how to write a correct compiler in C++ as fast as in Haskell, the only feeling I can express towards the author is pure and unadulterated awe.

PS: On that note, I've been shocked to discover that a horrified response from Haskell fans is expected. Haskell community is one of the friendliest and non-opinionated I've known, so I wonder why Haskellers are perceived as being akin to closet trolls.
