The CIA Just Dumped 12 Million Declassified Documents Online

After years of fighting with FOIA requesters, the CIA has finally uploaded over 12 million documents to its website . While many of the documents have been declassified for some time, the pages were intentionally hard to access, and only available on a few computers sitting at the National Archives. But now, anyone can… Read more…

Thousands Of Cubans Now Have Internet Access

There’s been a dramatic change in one of the world’s least-connected countries. An anonymous reader quotes the AP: Since the summer of 2015, the Cuban government has opened 240 public Wi-Fi spots in parks and on street corners across the country… The government estimates that 100, 000 Cubans connect to the internet daily. A new feature of urban life in Cuba is the sight of people sitting at all hours on street corners or park benches, their faces illuminated by the screen of smartphones connected by applications such as Facebook Messenger to relatives in Miami, Ecuador or other outposts of the Cuban diaspora… Cuban ingenuity has spread internet far beyond those public places: thousands of people grab the public signals through commercially available repeaters, imported illegally into Cuba and often sold for about $100 — double the original price. Mounted on rooftops, the repeaters grab the public signals and create a form of home internet increasingly available in private rentals for tourists and cafes and restaurants for Cubans and visitors alike. The article also points out that last month, for the first time ever, 2, 000 Cubans began receiving home internet access. Read more of this story at Slashdot.

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’s New Compression Tool Uses 75% Less Bandwidth Without Sacrificing Image Quality

An anonymous reader quotes a report from The Next Web: Google just released an image compression technology called RAISR (Rapid and Accurate Super Image Resolution) designed to save your precious data without sacrificing photo quality. Claiming to use up to 75 percent less bandwidth, RAISR analyzes both low and high-quality versions of the same image. Once analyzed, it learns what makes the larger version superior and simulates the differences on the smaller version. In essence, it’s using machine learning to create an Instagram-like filter to trick your eye into believing the lower-quality image is on par with its full-sized variant. Unfortunately for the majority of smartphone users, the tech only works on Google+ where Google claims to be upscaling over a billion images a week. If you don’t want to use Google+, you’ll just have to wait a little longer. Google plans to expand RAISR to more apps over the coming months. Hopefully that means Google Photos.

MIT Unveils New Material That’s Strongest and Lightest On Earth

A team of MIT researchers have created the world’s strongest and lightest material known to man using graphene. Futurism reports: Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions. But there’s one drawback: while notable for its thinness and unique electrical properties, it’s very difficult to create useful, three-dimensional materials out of graphene. Now, a team of MIT researchers discovered that taking small flakes of graphene and fusing them following a mesh-like structure not only retains the material’s strength, but the graphene also remains porous. Based on experiments conducted on 3D printed models, researchers have determined that this new material, with its distinct geometry, is actually stronger than graphene — making it 10 times stronger than steel, with only five percent of its density. The discovery of a material that is extremely strong but exceptionally lightweight will have numerous applications. As MIT reports: “The new findings show that the crucial aspect of the new 3-D forms has more to do with their unusual geometrical configuration than with the material itself, which suggests that similar strong, lightweight materials could be made from a variety of materials by creating similar geometric features.” Read more of this story at Slashdot.

Feds may let Playpen child porn suspect go to keep concealing their source code

Enlarge (credit: ullstein bild / Getty Images News) Rather than disclose the source code that the FBI used to target a child porn suspect, federal prosecutors in Tacoma, Washington recently  dropped their appeal in United States v. Michaud . The case is just one of  135 federal prosecutions nationwide involving the Tor-hidden child porn website Playpen.  The vast effort to bust Playpen has raised significant questions about the ethics, oversight, capabilities, and limitations of the government’s ability to hack criminal suspects. In United States v. Michaud , Jay Michaud of Vancouver, Washington allegedly logged on to Playpen in 2015. But unbeknownst to him at that point, federal investigators were temporarily operating the site for 13 days before shutting it down. As authorities controlled Playpen, the FBI deployed a sneaky piece of software (a “network investigative technique (NIT),” dubbed by many security experts as malware), which allowed them to reveal Playpen users’ true IP addresses. With that information in hand, identifying those suspects became trivial. Read 7 remaining paragraphs | Comments
