dryriver shares a report from Science Alert: According to a new study, it’s possible that all iron-based weapons and tools of the Bronze Age were forged using metal salvaged from meteorites. The finding has given experts a better insight into how these tools were created before humans worked out how to produce iron from its ore. While previous studies had found specific Bronze Age objects to be made from meteoric metal — like one of the daggers buried with King Tutankhamun — this latest research answers the question of just how widespread the practice was. Albert Jambon, from the National Centre for Scientific Research (CNRS) in France, studied museum artifacts from Egypt, Turkey, Syria, and China, analyzing them using an X-Ray Fluorescence Spectrometer to discover they all shared the same off-world origins. “The present results complementing high quality analyses from the literature suggest that most or all irons from the Bronze Age are derived from meteoritic iron, ” writes Jambon in his published paper. “The next step will be to determine where and when terrestrial iron smelting appeared for the first time.” Read more of this story at Slashdot.

schwit1 shares a report from Seeker: An ice-free corridor between the Americas and Asia opened up about 12, 500 years ago, allowing humans to cross over the Bering land bridge to settle what is now the United States and places beyond to the south. History books have conveyed that information for years to explain how the Americas were supposedly first settled by people, such as those from the Clovis culture. At least one part of the Americas was already occupied by humans before that time, however, says new research on the skeleton of a male youth found in Chan Hol cave near Tulum, Mexico. Dubbed the Young Man of Chan Hol, the remains date to 13, 000 years ago, according to a paper published in the journal PLOS ONE. How he arrived at the location remains a great mystery given the timing and the fact that Mexico is well over 4, 000 miles away from the Bering land crossing. For the new study, Gonzalez, Stinnesbeck, and their colleagues dated the Young Man of Chan Hol’s remains by analyzing the bones’ uranium, carbon, and oxygen isotopes, which were also found in stalagmite that had grown through the pelvic bone. The scientists believe that the resulting age of 13, 000 years could apply to at least two other skeletons found in caves around Tulum: a teenage female named Naia and a 25-30-year-old female named Eve of Naharon. Gonzalez said that the shape of the skulls suggests that Eve and the others “have more of an affinity with people from Southeast Asia.” He and his team further speculated that the individuals could have originated in Indonesia.

According to iClarified, a hacker by name of “xerub” has posted the decryption key for Apple’s Secure Enclave Processor (SEP) firmware. “The security coprocessor was introduced alongside the iPhone 5s and Touch ID, ” reports iClarified. “It performs secure services for the rest of the SOC and prevents the main processor from getting direct access to sensitive data. It runs its own operating system (SEPOS) which includes a kernel, drivers, services, and applications.” From the report: The Secure Enclave is responsible for processing fingerprint data from the Touch ID sensor, determining if there is a match against registered fingerprints, and then enabling access or purchases on behalf of the user. Communication between the processor and the Touch ID sensor takes place over a serial peripheral interface bus. The processor forwards the data to the Secure Enclave but can’t read it. It’s encrypted and authenticated with a session key that is negotiated using the device’s shared key that is provisioned for the Touch ID sensor and the Secure Enclave. The session key exchange uses AES key wrapping with both sides providing a random key that establishes the session key and uses AES-CCM transport encryption. Today, xerub announced the decryption key “is fully grown.” You can use img4lib to decrypt the firmware and xerub’s SEP firmware split tool to process. Decryption of the SEP Firmware will make it easier for hackers and security researchers to comb through the SEP for vulnerabilities. Read more of this story at Slashdot. 
sombragris writes: July 17 marked the 24th anniversary of Slackware Linux, the oldest GNU/Linux still in active development, being created in 1993 by Patrick Volkerding, who still serves as its BDFL. Version 14.2 was launched last year, and the development version (Slackware-current) currently offers kernel 4.9.38, gcc 7.1, glibc 2.25, mesa 17.1.5, and KDE and Xfce as official desktops, with many others available as 3rd party packages. Slackware is also among the Linux distributions which have not adopted systemd as its init system; instead, it uses a modified BSD init which is quite simple and effective. Slackware is known to be a solid, stable and fast setup, with easy defaults which is appreciated by many Linux users worldwide. Phoronix has a small writeup noting the anniversary and there’s also a nice reddit thread. Read more of this story at Slashdot. 
Slashdot reader midwestsilentone tipped us off to a growing problem. Lifehacker reports: New technology allows telemarketers to leave ringless voicemail messages, and it’s a method that’s gaining traction. While there are laws to regulate businesses when they call consumers, some groups argue that ringless voicemail shouldn’t count. The New York Times reports, “ringless voicemail providers and pro-business groups…argue that these messages should not qualify as calls and, therefore, should be exempt from consumer protection laws that ban similar types of telephone marketing”… After receiving a petition from a ringless voicemail provider, the Federal Trade Commission has started to collect public comments on this issue. So what can you do about it? First, you can head here to leave your public comment and if you’re getting these voicemails, you can file a complaint with the FCC here. Presumably that only applies if you’re in the U.S. But I’d be curious to hear how many Slashdot readers have experienced this. Read more of this story at Slashdot. 
An anonymous reader writes: Monday marks the seven-year anniversary of Bitcoin Pizza Day — the moment a programmer named Laszlo Hanyecz spent 10, 000 bitcoin on two Papa John’s pizzas. More important than the episode being widely recognized as the first transaction using the cryptocurrency is what it tells us about the bitcoin rally that saw it break through the $2, 100 mark on Monday. Bitcoin was trading as high as $2, 185.89 in the early hours of Monday morning, hitting a fresh record high, after first powering through the $2, 000 barrier over the weekend, according to CoinDesk data. Throughout the weekend, the value of cryptocurrency was looming around $2, 000. Read more of this story at Slashdot.
