  • Open Source Innovation Could Put a 3D Bioprinter in Your Living Room

    3D bioprinting traditionally requires high-level expertise, proprietary technology and a five-figure investment. A team of researchers from Carnegie Mellon University setout to change all that. In a paper published earlier this month in HardwareX, the group released the design of a fully functional 3D bioprinter it built by altering a widely available desktop 3D machine. The team’s innovation could be a game changer in terms of the overall accessibility of bioprinting.

    As desktop 3D printers become more robust, reliable, and feature-rich, we are seeing a definite shift in professional use-cases from prototyping to producing final products.

  • Unlock & Talk: Open Source Bootloader & Modem

    Since [Tom Nardi] introduced Hackaday readers to postmarketOS, the team has made progress on compiling a standard bootloader for MediaTek System-on-Chip (SoC) processors. Many Android phones use the MIT-licensed Little Kernel as the base of their bootloader and then apply custom closed-source modifications. [McBitter] has worked to eliminate this closed-source code by porting Little Kernel to the MT6735P used in the Coolpad Modena 2. By understanding the modifications MediaTek used for this particular SoC, the postmarketOS team hopes to use their modified, open-source Little Kernel bootloader with other MediaTek-based devices. While progress has been difficult and attempts at using emulators to probe bootloader memory have failed, [McBitter] was able to decode the DRAM configuration settings by searching for a leaked portion of the configuration strings. Now that he can set up the DRAM, there should be few barriers to running Little Kernel.

Single-unit version of Odroid-MC1 cluster computer adds flexibility

Hardkernel has launched a stackable single-unit Solo version of its 4-board Odroid-MC1 cluster computer. The system runs Linux on a octa-core Samsung Exynos5422 based Odroid-XU4S SBC.

Hardkernel has spun a single-unit version of its four-unit, 32-core Odroid-MC1 cluster computer for running Docker Swarm, Build Farm, and other parallel computing applications. The octa-core Odroid-MC1 Solo costs $48 instead of $220 for the original. The design offers greater flexibility, enabling users to combine Odroid-MC1 Solo units for a “single unit, 2, 3, 4, 5, 6, or n stackable cluster” or combine one or more Solo units with the original 4-unit MC1 to act as a single cluster,” says Hardkernel.

Calamares Pinebook

Hardware

But there is an under-appreciated bit regarding images for an ARM laptop — or pre-installed Linux distro’s in general. And that’s the first-run experience. The Netrunner Pinebook image is delivered so that it boots to the Plasma 5 desktop, no passwords asked, etc. The user is called “live”, the password is “live”, and nothing is personalized. It’s possible, though not particularly secure, to use the laptop this way in a truly disposable fashion. A first-run application helps finalize the configuration of the device by creating a named user, among other things.

One of the under-documented features of Calamares is that it can operate as a first-run application as well as a system installer. This is called “OEM Mode“, because it’s of greatest interest to OEMs .. but also to distro’s that ship an image for users to flash onto (micro)SD card for use in a device.

While some IoT devices can be evaluated from a purely software standpoint (perhaps reverse engineering the mobile application is sufficient for your needs), a lot more can be learned about the device by interacting with all the interfaces available (often including ones not intended for access, such as debug and internal interfaces).

Ubuntu

Kontron’s “ACE Flight 1600 Gateway Router” avionics computer runs Linux on a Bay Trail Atom, and provides a 5-port, L2-managed GbE switch, 4G LTE Advanced-Pro, 802.11ac, and DO-160G compliance.

Kontron’s has added to its ACE Flight product line with a compact low-end router computer designed for small commercial jets and business jets. The fanless ACE Flight 1600 Gateway Router is a small form factor avionics networking platform that consolidates wireless connectivity, switching, routing, and security features. “A typical routing application is the secure interface from client devices onboard the aircraft to SATCOM or Air-To-Ground connectivity links,” says Kontron.

The user then writes configuration objects to capture the workflow logic.

  • The developer of Helium Rain gave an update on their sales, low overall sales but a high Linux percentage
    Helium Rain [Steam, Official Site], the gorgeous space sim from Deimos Games is really quite good so it's a shame they've seen such low overall sales. In total, they've had around 14,000€ (~$17,000) in sales which is not a lot for a game at all. The good news, is that out of the two thousand copies they say they've sold, a huge 14% of them have come from Linux. It's worth noting, that number has actually gone up since we last spoke to them, where they gave us a figure of 11% sales on Linux.

  • IRS Website Crash Reminder of HealthCare.gov Debacle as OMB Pushes Open Source
    OMB is increasingly pushing agencies to adopt open source solutions, and in 2016 launched a pilot project requiring at least 20 percent of custom developed code to be released as open source – partly to strengthen and help maintain it by tapping a community of developers. OMB memo M-16-21 further asks agencies to make any code they develop available throughout the federal government in order to encourage its reuse. “Open source solutions give agencies access to a broad community of developers and the latest advancements in technology, which can help alleviate the issues of stagnated or out-dated systems while increasing flexibility as agency missions evolve over time,” says Henry Sowell, chief information security officer at Hortonworks Federal. “Enterprise open source also allows government agencies to reduce the risk of vendor lock-in and the vulnerabilities of un-supported software,” he adds.
  • Migrations: the sole scalable fix to tech debt.

    Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order of magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. This isn't because they're bad processes or poor tools, quite the opposite: the fact that something stops working at significantly increased scale is a sign that it was designed appropriately to the previous constraints rather than being over designed.

    A mobile application built by a third party for the RSA security conference in San Francisco this week was found to have a few security issues of its own—including hard-coded security keys and passwords that allowed a researcher to extract the conference's attendee list. The conference organizers acknowledged the vulnerability on Twitter, but they say that only the first and last names of 114 attendees were exposed.

    In a yet-to-be peer-reviewed study published on Freedom To Tinker, a site hosted by Princeton's Center for Information Technology Policy, three researchers document how third-party tracking scripts have the capability to scoop up information from Facebook's login API without users knowing. The tracking scripts documented by Steven Englehardt, Gunes Acar, and Arvind Narayanan represent a small slice of the invisible tracking ecosystem that follows users around the web largely without their knowledge.
