Check out IHaskell - https://github.com/gibiansky/IHaskell

It lets you do multiline stuff, and you get to see the output right away. You don't need let, or to repeat the "main = do ..." every time you want to run a block of code.

I think it's really helpful when you're starting out.

Actually it could be. Let's say there's this beacon software that lets you look a bit into how someone interacts. Say you get to know what 'spending tier' they're in - high, medium, or low. You also get to see how much 'social influence' they have - again, high, medium, low. Why would you give a free hot dog to someone in the low-low tier? You probably wouldn't, but right now you have to carpet bomb free stuff. Select who gets your free stuff so you can maximize your influence. Have it pop up when someone is walking down your street, at a particular time of day.

When the big spender with a lot of friends walks by, drunk, at 2:30 in the morning home from the bar, send him a free sandwich coupon when he hits your street. Throw in a bag of chips and a pop, make it 'special'. Perfect advertisement to target the perfect people.

Your software lets companies deliver freebies to 'important' people when they're nearby. Have some automated identity finders - find them on fb, g+, twitter, see how much reach they have. Give them some free stuff, see if they tweet about it, put them a bit higher in the ranks because they gave a good word (or any word at all).

That's an awesome chord keyboard - http://www.youtube.com/watch?v=yJDv-zdhzMY#t=2039 I've always wondered why more people don't use them. It seems significantly less prone to errors - instead of fat fingers or incorrect placement, you have to coordinate the timing between the fingers.

It's pretty amazing how much that video demonstrates. I wonder what the next version of that video will be. Hopefully it's not computer related.

I wish there was more of this type of information about injection molding, that seems like more of a dark art than electronic assembly.

What do you guys think of having the component manufacturer source the parts? I've seen some that purchase parts directly from Digikey, but I'm not sure if they pool together orders for discounts, or if they just handle the purchasing so you don't have to. It seems like they could get a better deal than I could (I always assumed that a manufacturer would try to source locally in China and get stuff for dirt cheap, but they buy from Digikey too - seems kind of strange).

Does anyone know any good US based contract manufacturers? All the ones I've seen are ridiculously expensive ($17 for a 4" x 1" board with ~60 components, as opposed to ~$6 at Myro (thanks theunixbeard for catching that error)). I'd love to get something made here in the US, but I can't eat another $10 for my lights - especially for a service like assembly (where the quality seems like it won't matter that much - the light will work or it won't work). I've been toying with the idea of a stretch goal on Kickstarter to assemble some delta bots to do the electronic assembly (it'd be about $1200 for a single bot, whereas contract manufacturing is about $2000, but I'd have something to show for that money with a pick and place machine). Having a machine where you could throw a stenciled PCB on in any orientation, then pick and place the parts onto, and cook it on the spot (moving the camera up and watching for reflow) would be pretty awesome.

It's sticky being in the 'middle' - big enough where you need to use services rather than hand assembly, but small enough where you don't really have any purchasing power. The road to production has a big no man's land in the middle.

Ch00f has a great write up on the process of going through with contract manufacturing, and some of the hurdles he saw with the process - http://ch00ftech.com/2013/04/16/making-55-of-something-witho...

Can anyone explain to me how they're worth $3 billion dollars? They haven't produced anything, they haven't advanced humanity, they have the eyeballs of teens - for the moment, until something cooler comes along. Are they really that valuable? It doesn't seem like there's any show stoppers for creating a snapchat clone (rather than having X users at the moment), and if snapchat were to start making money - say by sending ads to endorse a product rather than a user generated picture, people would probably start leaving the platform towards the newest green pasture.

I recently got a new phone, and I got hooked in to all the services my friends were talking about in recent memory - instagram's dead, twitter's dead, snap chat is in flux. Not for all users, but in my group of friends these services aren't used as much. There isn't really anything keeping you from moving onto something new - your digital life isn't really that valuable. It's probably better to not read the conversations you had a year ago. The pictures are always nice, that's probably the only thing that people would care about, but with Snapchat they're gone (unless you hit save). I'm not sure what I'm getting at, but this company isn't worth $3 billion dollars.

That's kind of interesting. They seem to be tracking the expected delivery date really well. At first, it says 1-2 business days. Then it went to November 5th, then it moved to November 8th. The black 16gb is moving the quickest at the moment.

What's the point of having google.com/nexus/5, when people are going to be purchasing it from the play store (splitting traffic, rather than sending it all to the store)?

Edit: www.google.com/nexus/5 is live now.

That sounds nice actually. It might not be for a little bit yet (got some more design to do first), but send me an email (in my profile) to touch base.

That wasn't intended to be the final one, but I made it and it worked. It was printed with support material that peeled off a little too strongly, exfoliating the back surface. The orientation is kind of tricky as there's a lip/groove interface between the front and back of the case which needs to be cosmetically clean to ensure a snug fit, so the only way to get that to work well is to print it with the back down, but there's a 'hood' over the ethernet connector that disallows printing directly onto the back. Slicing with slic3r.

That's something I only put a little bit of thought into, as I'm not very worried about my bike getting stolen.

It would be non-functional if someone stole it without stealing the magnet and reed switch as well, but they wouldn't know that.

There's a bit of a trade off, as you're going to want to remove the light to charge it up, in that if you want it to remove easy, it will be easy to steal, and if you want it to be hard to steal, it will be a pain to charge. I don't have any solutions for that yet.

I actually went to the local university - they said that you can't use university resources for personal gain (I was trying to print a case on their 3D printer). I'm sure there would be some people in the engineering department willing to give me some pointers, there's also a local prototyping company (I've emailed them a few times). Nothing too serious though - I guess I don't really have much of a plan yet, and didn't want to rush into getting roped into sticky situations.

Thanks for asking the questions - I just reached out to a friend who said he'd help me before, maybe this thing will start rolling :).
