Tor Onion Browser’s Creator Explains Free Version For iOS

The free iOS version of the Tor browser “sparked a tidal wave of interest” after its release in December, according to Silicon.co. Mickeycaskill writes: The cost has been scrapped due to developer Mike Tigas’ worries that the price was limiting access to anonymous browsing for those who need it most. “Given recent events, many believe it’s more important than ever to exercise and support freedom of speech, privacy rights, and digital security, ” Tigas wrote in a blog post. “I think now is as good a time as ever to make Onion Browser more accessible to everyone.” “I’m still a little terrified that I’ve made this change, ” Tigas adds. For four years the Tor Onion browser was available on the Apple App Store for $0.99, the lowest non-free price allowed by Apple, providing a “reliable” income to Tigas which helped him move to New York for a new job while allowing him “the economic freedom to continue working on side projects that have a positive impact in the world.” Tigas also writes that “there’s now a Patreon page and other ways to support the project.” Last month the Tor Project also released the first alpha version of the sandboxed Tor Browser.

Open Source Codec Encodes Voice Into Only 700 Bits Per Second

Longtime Slashdot reader Bruce Perens writes: David Rowe VK5DGR has been working on ultra-low-bandwidth digital voice codecs for years, and his latest quest has been to come up with a digital codec that would compete well with single-sideband modulation used by ham contesters to score the longest-distance communications using HF radio. A new codec records clear, but not hi-fi, voice in 700 bits per second — that’s 88 bytes per second. Connected to an already-existing Open Source digital modem, it might beat SSB. Obviously there are other uses for recording voice at ultra-low-bandwidth. Many smartphones could record your voice for your entire life using their existing storage. A single IP packet could carry 15 seconds of speech. Ultra-low-bandwidth codecs don’t help conventional VoIP, though. The payload size for low-latency voice is only a few bytes, and the packet overhead will be at least 10 times that size. Read more of this story at Slashdot.

Google turns Toontastic into a 3D storytelling app

Google Education has launched a 3D version of Toontastic, almost two years after Mountain View bought the company that created it. The new Toontastic stays true to the original version: it’s still a storybook app, except now kids can work with 3D characters and environments. They can animate short three-dimensional movies by customizing characters and placing them in interactive scenarios, or they can use the tool to make projects for school. Google describes the updated Toontastic as some sort of a digital puppet theater. The app is now out on the App Store and on Google Play for phones, tablets and select Chromebooks. Mountain View’s Education division regularly works on projects kids can learn from and enjoy, such as initiatives that teach them how to code . Last year, it developed a way to make exploring the Himalayas online more fun with the help of a friendly jetpack-riding yeti named Verne. It also once offered a $30, 000 scholarship prize for a Google Doodle contest featuring K-12 students in the US. Source: Google Education

The amazing whistling language of Greek shepherds

In the village of Antia on Greece’s Evia island, shepherds use whistling to communicate over long distances. This isn’t a code but rather a real language. “Whistles let shepherds communicate between distant hillsides because a whistled sound wave travels farther than spoken words.” ( Scientific American )

Private company says it is fully funded for mission to the Moon

An artist’s concept of Moon Express’ MX-1 lander on the surface of the Moon. (credit: Moon Express) Any organization wishing to accomplish a major spaceflight goal must address two basic sets of problems—rocket science and political science. And while the technical challenges of spaceflight are considerable, it’s arguable that political science remains the greater of these two hurdles. Building spacecraft and rockets requires lots of money, after all, and due to international law they can’t just be launched from anywhere to anywhere. So it is no small achievement for the private, US-based Moon Express to have conquered the political science part of sending a rover to the Moon. Last August, after a lengthy regulatory process, the company received permission from the US government to send a commercial mission beyond low Earth orbit. And on Friday, the company announced that it has successfully raised an additional $20 million, meaning it has full funding for its maiden lunar mission. “Now it’s just about the rocket science stuff,” said company co-founder and Chief Executive Bob Richards. That, he realizes, remains a formidable challenge. Moon Express is one of five entrants in the Google Lunar X Prize competition to finalize a launch contract. Each of the teams is competing to become the first to send a rover to the lunar surface by the end of this year, have it travel 500 meters, and transmit high-definition imagery back to Earth. First prize is $20 million. Read 6 remaining paragraphs | Comments
