NextVR 6x6K Omnidirectional Camera Rig

Engadget reports on an omnidirectional camera system made of 6 synchronized RED EPIC Dragons with 6K resolution (6144x3160) each, by NextVR. Used to broadcast live events with look-around capabilities (only horizontal). Will need fisheye lenses to provide overlapping views for stitching.

Transcript: Feynmann Lectures on Physics

Io9 and Open Culture report that some Lecture Transcripts of Richard Feynmann, famed physicist and explainer, have been completed by Caltech. Previously, 7 lecture videos had been made available.

Open Source Game Clones

A surprising number of classic games have open source clones: Zelda (Solarus), Super Mario (Mega Mario), Paradroid (FreeDroid), Syndicate (FreeSynd) and of course, Counter Strike (Urban Terror).

Metal Gear Solid V: Character Making-Of

Hideo Kojima's team shows a making-of video for the female character "Quiet": markerless 3D scanning of a real person's face, and subsequent modeling. For the Cyberpunk 2077 trailer (making-of) from Platigue, a similar but denser camera array was used by Infinite Realities.

Thomas Piketty's Capital

Boingboing reports on the "Capital in the 21st century" book by Thomas Piketty: 300 years of Europa/USA economic data are analyzed on how much bigger capital gains (r) are than work gains (g). While r > g always holds true, large-scale capital-destroying events reduce the effect, while quieter times mean more wealth concentration.

Linux Undelete with Grep

Alex Clemmer with a nice little trick to recover deleted text files under Linux: Just use grep on /dev/mypartion. Seems obvious once you heard it... and will even work on encrypted partions with /dev/mapper/mycrypt.

IRIS: Solar Flare in Detail

Io9 points to a NASA report on the IRIS satellite (2013), recording a solar flare up close in the ultraviolet spectrum: Looking at a sunspot from the side, some coronal loops visible, then the solar flare (size: about 4 earths) erupting before the accompanying CME (coronal mass ejection). In related news: Io9 on the earth's magnetic field via ESA Swarm (3 satellites).

Busier than Ever

The Atlantic examines the development of leisure (USA only) -- overall work hours have declined, but there is one exception: A very long education leads to more work than previously in history, and only shorter educations lead to more leisure. Related: Business Insider writes on the perception of time by different cultures; and Quora discusses common management mistakes.

Input Device: Hover-Swipe Keyboard

Microsoft Research has built a prototype keyboard with built-in touchpad: Between the keys, infrared sensors (96 in total) track any hovering fingers, and a machine learning algorithm determines whether and which swipe gesture has occured. In unrelated news: Why you should not interrupt a programmer (comic).

Luke Arm: Production Ready

Slashdot points to a Makezine article on FDA approval of the DEKA ("Luke") arm, meaning that the prosthetic arm is production-ready (not only a DARPA prototype). It reads EEG signals and has 12 pre-programmed modes for basic grips, e.g. "insert and turn key", "open marmelade jar", providing highly specialized manual actions.

SSH Kung-Fu

The Tyblog summarizes useful SSH operations, among them: Reverse SSH to overcome NAT'ed hosts; SSH tunneling to work around restricted port ranges; and mounting remote filesystems with sshfs.

On Latency: TCP vs UDP

The 1024 monkeys blog writes about TCP vs. UDP networking for games: While implementing custom persistency with UDP is always reliably faster, TCP may be already good enough -- if the slightly flawed congestion control strategy can be tolerated.
