What 3D Printing Is Like When You’ve Never Done It Before


Gigaom

I thought it would be as easy as hitting print. Then, voila a miniature robot! A pencil holder! A pair of stunner shades! A Bulbasaur planter!

3D printing has the potential to change everything in our world: the Army is considering using it as an easy way to replace parts during war, and NASA even just sent a printer to space. So when I was given the chance to try printing an object for the first time, of course I wanted to try it.

Then I opened the lid on the 3D printer and saw a wet tangled mess of lasered plastic. Oh. 3D printing, it turns out, is not the perfect life-changing tool I had imagined.

While my colleague Signe Brewster can tell the difference between objects that came off a really great 3D printer and those produced by a mediocre one, I looked down at a lump of…

A “Privacy Checkup” From Facebook


Gigaom

Facebook has rolled out its long-awaited privacy “checkup” button. The checkup is exactly what it sounds like — a way to quickly scan your activity on the site and see who can view your activity.

This Is Who/What Facebook Thinks You Are/Like


Last quarter, Facebook made $2.8 billion off our personal information. Starting this summer, the social network is letting us see exactly what pieces of our online identities it reveals to advertisers.

Learn how, find out why you’ve been targeted and check what else Facebook thinks you like

Facebook has spent years mining from your online activity, against which it sells hyper-targeted advertising. If you are one of Facebook’s 204 million users in the United States and Canada, the social network made about $5.79 in advertising revenue off you last quarter.

On some level, we all know that Facebook does this, and on some level we all accept it. But starting this summer, Facebook is letting us lift the curtain and see exactly what pieces of our online identities it reveals to advertisers. If you hover over the top, right-hand corner of any Facebook ad, you can access a dropdown menu that will let you hide certain ads, rate ads as helpful, or — this is the interesting part — see why a particular advertiser chose to target you.
Among the potential reasons: your age, your gender, your location, pages you’ve liked, pages your friends have liked, your propensity to click on similar ads, where you shop online, what kind of phone you have, your inferred hobbies … or “other reasons”.TIME
