this is pretty much how my conversations go when I tell people that I want to buy a 3d printer.


I could probably build a 3D printer from scratch, controller, actuators, and all, and I still ask myself the "What is this thing good for?" question.

Okay, sarcasm aside, it looks like these things are finally starting to slowly crack the door open on the realm of real-world usability. This realization dawned on me when I figured that some parts of the quadcopter I've been toiling over in recent days, might as well be 3D printed: the battery holder, maybe the motor mounts, etc. Gimbal parts would be pretty easy too.

And it dawned on me again yesterday, during SpaceX's dog and pony show for the Dragon 2, when they showed the 3D printed rocket engines.


That's precisely what makes me so excited about them (and physical computing in general). The next Jobs/Woz team is working on that stuff right now and it seems as weird to the layperson as PCs did back when the Berkley Homebrew Club was doing its thing.


One reason to justify Google's cut is that on an advertising deal where the Advertiser gets billed for each click (CPC) on his link on someone else website, having a reliable third party to count the clicks is very important.

Click fraud is what makes Tier 2 CPC networks really risky for advertisers even if CPC are much lower than Tier 1 (Adwords, Bing).

Regarding your Adsense example, was there not a mention like "Ads by Google," "Sponsored Links," or the AdChoices icon ? In that case, it makes clear that it's not a natural link.


Actually it goes like that:

You own a website, I own a website. I pay you $100 to show your visitors a link to my website. The link is presented as an organic, non paid link. =BAD

You own a website, I own a website. I pay you $100 to show your visitors a link to my website. The link is presented as a paid link, with a no follow attribute. =GOOD

On a side note, your breakdown of the Ad Revenue using Google as a middleman is wrong. If you pay Google 100$ (via Adwords) to decide to show ad on my site, I will get 68% of that 100$ and Google will get 32%

Bitcoin newbie here, so it's probably something obvious, but can I buy Bitcoin from this app ? I wasn't sure if the "receive Bitcoin" meant that.


No, you cannot use this app to buy bitcoins. So I'm afraid it does not solve one of the hardest challenges Bitcoin still faces, which is how to get any. You'll have to figure out the best/cheapest way depending on where you are.

If you happen, for example, to stand in front of a Bitcoin ATM, you can use that to turn fiat that you have in the form of cash into fiat that you have in your Bridgewalker account (by buying Bitcoin from the ATM and sending it to your Bridgewalker address), which you can then later spend wherever it says "Bitcoin accepted here".

A lot of exchanging back and forth for sure, but basically the idea of "Bitcoin only as tranfer mechanism" applied at every step. It's also just a technical prototype. In practice it might make sense to cut some of those exchange fees by having a more direct way to fund your account, at the cost of only being available in certain markets/countries. For this prototype I went with the easiest solution: only Bitcoin in, and Bitcoin out.


Presumably you can create a wallet and use this to send bitcoins to it?


Doesn't look like it. You fund it with bitcoins which it converts to euros


I prefered the 2012 version. The blue titles stood out more and made it easier to scan the articles of the front page in one go


A good way to avoid articles on those big companies is to start reading "region specific" startup blogs or "topic specific" startup blogs. Some of the blogs I follow:

by region

Arctic Startups (Scandinavia) http://www.arcticstartup.com/

Rude Baguette (France) http://www.rudebaguette.com/

Silicon Allee (Berlin) http://siliconallee.com/

by topic

Can someone explain why this is a significant decision ?


when you write Adsense, do you mean Adwords ?


No, I mean Adsense. Adwords is intent-driven search. Adsense is discovery. Pinterest is much more comparable to Adsense.


I thought AdWords was the interface for making ads for AdSense. The logo even says "Google AdWords." And the ads I made look a lot like AdSense.


They're different products. Adwords ads go on google.com, Adsense ads are put on the display network (blogs, gmail, etc.) Now you can create both through the Adwords tools, but they're still separate offerings.


AdSense is a product for publishers that allows to monetize their traffic. AdWords ia a product to place ads on google search and google display network which includes google properties (youtube, gmail). They are two sides of the same coin, directed on publishers and advertisers respectively.



AdWords is the portal but you can target search or the content network (aka AdSense).


blah the HN app I was using gave me no notification that a comment was posted. I wasn't trying to spam.


You will be forever shunned for this grievous error.


it sounds like they mean using AdWords but targeting the content network, which is effectively the AdSense network. That is different then search engine traffic that you can also buy through AdWords.


This is mostly semantics.

AdWords is the overall interface. Adssense is the website-owner-focused product that lets people put ads on their website. AdSense is for all intents & purposes google's display network, but is definitely served up through Google's AdWords platform.


I think he means 'Google Display Network', which is what puts adverts on sites using 'Google AdSense'.


I use http://ihackernews.com/ on my mobile. The only issue is that sometimes comments are not displayed because the app reach the api requests limit. Any similar issue with your app ?


Hmm. I have not experienced that with mine, but than I don't have that many users.


Speaking of their error page, they have a typo on there. "...to many requests" instead of "...too many".


It doesn't look like anyone knew... "Alcatel-Lucent's corporate representative, at the heart of its massive licensing campaign, couldn't even name the technology or the patents it was suing Newegg over."
