Chuck Hull of 3D Systems invented the first-ever 3D printer in the early 1980s. The first thing he printed? A tiny cup that could serve as an eye wash, according to a CNN interview. The printer worked similarly to its descendants today: a laser seals together particles of material to build an object layer by layer.

T-Mobile(s tmus) customers with a fear of commitment will be able to upgrade their handset at any time thanks to modifications of the carrier’s Jump plan. Starting later this month, the 6-month waiting period for phone upgrades will be dropped but not without a catch: Under the new terms, T-Mobile will only cover half of the old phone’s remaining balance.

The updated plan details were first spotted by T-Mo News on on Thursday. The site then published a T-Mobile PR statement on Friday with the following details:

T-Mobile sparked a revolution in the wireless industry in 2013, beginning with the elimination of service contracts and a call for ‘Contract Freedom.’ Our innovative JUMP! handset upgrade program is an important cornerstone of our Un-carrier movement, and soon (starting February 23) you will be able to upgrade as many times as you like:

Microsoft’s(s msft) marketing chief Tami Reller gave the impression to some at Goldman Sachs’ technology conference Thursday that Office for non-Windows platforms isn’t go to happen. That’s a direct contradiction of statements by then-CEO, Steve Ballmer, in September of last year. So which is it: Is Office for iPad(s aapl) coming or not?

Microsoft watcher Mary Jo Foley says it is and perhaps sooner even than a Metro or touch-friendly version of Office for Windows 8.1. In a post on Friday, Foley shared information from her sources, saying the code name for the software is “Mirimar” and that it’s expected in the first half of 2014.

There’s no information yet on how the software would be made available, but I agree with Foley: It’s sure to tie in directly to Microsoft OneDrive, which is the new name for SkyDrive. And it could even require a Microsoft Office 365 subscription…

Even critics of massive open online courses, better known as MOOCs, shouldn’t deny the value of the student data those courses generate. Teachers can only gather insights into how engaged students really are with the material and how well they’re understanding it if they’re using a platform designed specifically to capture that data. MOOCs do this very well, and now University of Michigan meteorology professor Perry Samson (who also co-founded Weather Underground) has developed software to let his peers in lecture halls do the same.

The platform is called LectureTools, and it has some obvious benefits around helping ensure students engage with a course more than is naturally possible in a room full of 250 people. While class is in session, LectureTools lets professors quiz students using a variety of different formats, lets students submit questions and note when a slide confuses them, and even lets professors…
