11:46 PM | Testing: Lenovo Yoga 3 Pro Laptop
We're at a bit of a crossroads for Windows-based laptops. With Windows 10 coming out next year, the laptops on sale this holiday may be the last new generation to be designed with Windows 8.1 in mind, with all of the OS's quirks and shortcomings (touch on the Desktop and high DPI screen management still not perfected). My hope is that laptops like Lenovo's new Yoga Pro 3 to thrive in Windows 10--I can't wait for that virtual desktop manager--but you don't buy a laptop today to unlock its […]

10:24 PM | In Brief: Good Tips for 3D Printing Adhesion Problems
The base cause of most 3D printing failures is some sort of problem with adhesion. If that first layer of plastic doesn't stick to your print bed, it's almost inevitable that the print will fail. I love this list of tips and tricks to improve adhesion that Make posted. It's got several of my personal favorites--level that build platform, ensure the print head is the right distance from the bed, and always wipe the print surface with isopropyl or acetone to remove fingerprint oil--but they also […]

In past episodes of Still Untitled and most recently in the video with animator Marty Cooper, Adam has talked about the influence of his father's cartoons and animations on his life and art sensibilities. We got glimpses of the work of Lee Savage did for shows like Sesame Street, and Adam shares more of his memories in this guest post for AV Club to commemorate the show's 45th anniversary. It's a touching tribute.

The gallery is accompanied by a few video clips of the finished animation sequences, some behind-the-scenes […]

2:54 AM | Veterans Day
Veterans Day is a federal holiday, but, at Harvard classes go on.  This year, the holiday is observed for staff, but we'll be teaching.I can't easily find out when the practice of having classes on Veterans Day became standard.  I found this Crimson article from 2004, but it makes it sound like holding classes (it seems to just mention sections, not actual lectures) was not official policy.  I also am not sure when this dichotomy of the day being a staff holiday, but classes are […]

11:17 AM | [Twitter Studies] Rewriting history in 140 characters
What is the role of historians on Twitter? To share historical content on social media has become common, exacerbated this year by the commemorations of the First World War. But strategy and rigor (and therefore the quality of cultural mediation) are highly variable. The analysis proposed here offers some remarks on “best practices”, developed in three typologies: Engagement typology: a measure is already a classification Content typology: what do we put in […] The […]

4:35 PM | The first ever Robust PCA applied in Imaging
One of the first ever analog Robust PCA applied in imaging happened in 1838 as Louis Daguerre took this photo. From wikipedia:"Boulevard du Temple", taken by Daguerre in 1838 in Paris, includes the earliest known candid photograph of a person. The image shows a street, but because of the over ten-minute exposure time the moving traffic does not appear. At the lower left, however, a man apparently having his boots polished, and the bootblack polishing them, were motionless enough for […]

6:00 PM | Battery Life on Android: Does the mAh Rating Tell the Whole Story?
Smartphones have gotten faster and larger over the years, but we still often struggle with battery life even on flagship Android devices with gigantic batteries. The device in your pocket is more powerful that supercomputers in the early 90s and might have four times as many pixels as your TV, but most of them still beg for a charger in a day or so. Is it really worth it? More importantly, can you tell how well a phone will perform based solely on the size of the battery? Let's take a look at […]

Today we have a mix of interesting papers, some of which will be featured at NIPS 2014 A differential equation for modeling Nesterov's accelerated gradient method: theory and insights by Weijie Su, Stephen Boyd, Emmanuel J. CandesWe derive a second-order ordinary differential equation (ODE), which is the limit of Nesterov’s accelerated gradient method. This ODE exhibits approximate equivalence to Nesterov’s scheme and thus can serve as a tool for analysis. We show that the […]

9:30 PM | The Terminator and the Legacy of Stan Winston's Designs
With photos and story details of the upcoming Terminator reboot coming to light, we wanted to take a look back at the original film and examine how and why it still holds up after all these years. Like a lot of movies that became cultural touchstones and phenomenons, The Terminator was under-estimated, dismissed by Orion Pictures as a low budget drive-in film that would come and go in a week. Yet The Terminator became a major sleeper that connected with audiences in a big way. It was the top […]
