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.

Hacker Steals 900 GB of Cellebrite Data

An anonymous reader shares a Motherboard report: Motherboard has obtained 900 GB of data related to Cellebrite, one of the most popular companies in the mobile phone hacking industry. The cache includes customer information, databases, and a vast amount of technical data regarding Cellebrite’s products. The breach is the latest chapter in a growing trend of hackers taking matters into their own hands, and stealing information from companies that specialize in surveillance or hacking technologies. Cellebrite is an Israeli company whose main product, a typically laptop-sized device called the Universal Forensic Extraction Device (UFED), can rip data from thousands of different models of mobile phones. That data can include SMS messages, emails, call logs, and much more, as long as the UFED user is in physical possession of the phone. Read more of this story at Slashdot.

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.

Fewer People Are Dying of Cancer Than Ever Before

The number of Americans dying of cancer has dropped to a 25-year low, equaling an estimated 2, 143, 200 fewer deaths in that period, says the new annual report from the American Cancer Society. In that time, the racial and gender disparities that exist in cancer rates have also narrowed somewhat, but they remain wide in many places. From a report on The Outline: Though the incidence of cancer remained stable for women and dropped slightly — by 2 percent — in men, rates remain overall 20 percent higher in men while rate of death for men is 40 percent higher than in women. The rates of both incidence and death vary wildly based on the type of cancer. The data that the ACS is using run through the end of 2014 for incidents of cancer and through 2013 for deaths. Lung cancer remains the leading cause of cancer death in the United States for both men and women.. Read more of this story at Slashdot.

A Squishy Clockwork BioBot Releases Doses of Drugs Inside the Body

the_newsbeagle writes: Making micro-machines that work inside the body is tricky, because hard silicon and metal devices can cause problems. So bioengineers are working on soft and squishy gadgets that can be implanted and do useful work. Here’s a soft biobot that’s modeled on a Swiss watch mechanism called a Geneva drive. With every tick forward, the tiny gizmo releases a dose of drugs. Getting the material properties just right was a challenge. “If your material is collapsing like jello, it’s hard to make robots out of it, ” says inventor Samuel Sia.

Over 1,800 MongoDB Databases Held For Ransom By Mysterious Attacker

An anonymous reader writes: “An attacker going by the name of Harak1r1 is hijacking unprotected MongoDB databases, stealing and replacing their content, and asking for a 0.2 Bitcoin ($200) ransom to return the data, ” reports Bleeping Computer. According to John Matherly, Shodan founder, over 1, 800 MongoDB databases have had their content replaced with a table called WARNING that contains the ransom note. Spotted by security researcher Victor Gevers, these databases are MongoDB instances that feature no administrator password and are exposed to external connections from the internet. Database owners in China have been hit, while Bleeping Computer and MacKeeper have confirmed other infections, one which hit a prominent U.S. healthcare organization and blocked access to over 200, 000 user records. These attacks are somewhat similar to attacks on Redis servers in 2016, when an unknown attacker had hijacked and installed the Fairware ransomware on hundreds of Linux servers running Redis DB. The two series of attacks don’t appear to be related. Read more of this story at Slashdot.

Baby’s Skull Rebuilt With Help From A 3D Printer

schwit1 writes: A team at Stony Brook Children’s Hospital was able to use a 3-D printer to produce a replica of baby Vincent’s skull, which, in turn, allowed the medical team to fully rehearse the surgery long before they stepped into the operating room. Through a collaboration with Medical Modeling in Colorado, known now as 3D Systems, Egnor and Duboys were able to virtually plan the entire surgery in advance. Duboys said images from a CT scan of baby Vincent’s head were sent to the company, which then manufactured a model skull using the CT information as a template. The company also created a model of what Vincent’s skull should look like after surgery. Read more of this story at Slashdot.

Pull Requests Are Accepted At About The Same Rate, Regardless of Gender

An anonymous reader writes: Remember that story about how women “get pull requests accepted more (except when you know they’re women).” The study actually showed that men also had their code accepted more often when their gender wasn’t known, according to Tech In Asia — and more importantly, the lower acceptance rates (for both men and women) applied mostly to code submitters from outside the GitHub community. “Among insiders, there’s no evidence of discrimination against women. In fact, the reverse is true: women who are on the inside and whose genders are easy to discern get more of their code approved, and to a statistically significant degree.” Eight months after the story ran, the BBC finally re-wrote their original headline (“Women write better code, study suggests”) and added the crucial detail that acceptance rates for women fell “if they were not regulars on the service and were identified by their gender.” Read more of this story at Slashdot.
