    Joshua Pearce, a prolific engineer at Michigan Tech, has been working on developing an affordable metal 3D printing technology. The project involves hacking a CNC router kit and an metal inert gas (MIG) welder to create a low-cost GMAW metal 3D printer.

  • 3D Printed, Open Source Glia Stethoscope Receives Clinical Validation

    Dr. Tarek Loubani spent some time working in hospitals in the Gaza Strip during the worst of the chaos and violence that is unfortunately still going on there. Due to a long-standing blockade, medical supplies were scarce in the region – so scarce that doctors could often not find a stethoscope when they needed one. So Dr. Loubani came up with his own solution – he 3D printed a stethoscope, for about 30 cents.

Security: 17 Things

Filed under

A list for protecting yourself and others from the most common and easiest-to-pull-off security crimes.

I spend a lot of time giving information security advice, such as why RMF (Risk Management Framework) is too top-heavy for implementing risk management practices in small or R&D-focused organizations, what the right Apache SSL settings really are or how static analysis can help improve C code. What I'm asked for the most though isn't any of those things; it's the everyday stuff that even non-technical people can do to protect themselves from the looming but nebulous threat of an information security accident.

  • Univa Taps Open Source Community to Bolster Enterprise HPC

    Univa is looking to the open source community to help evolve its Navops Launch platform for enterprises migrating high-performance computing (HPC) workloads to the cloud. The open source efforts will run under the Project Tortuga banner, with access available through an Apache 2.0 license model.

    Rob LaLonde, general manager and vice president for Navops at Univa, explained that the open source plan will focus on general purpose cluster and cloud management frameworks. This includes the ability to automate the deployment of clusters in local on-premises, cloud-based, and hybrid-cloud configurations. These will be applicable to applications like HPC, big data frameworks, Kubernetes, machine learning, and deep learning environments.

  • Univa Open Sources Project Tortuga

    Univa, a leading innovator in on-premise and hybrid cloud workload management solutions for enterprise HPC customers, announced the contribution of its Navops Launch (née Unicloud) product to the open source community as Project Tortuga under an Apache 2.0 license to help proliferate the transition of enterprise HPC workloads to the cloud.

  • Google Open-Sources Impressive AI Camera Tools

    People use smartphones for lots of different reasons. Some folks like to browse the web. Some like to listen to music. Some like to spend infinite money on bad mobile games. And some people even still like to make phone calls. But one of the biggest selling points of a modern phone is the quality of its camera. Gone are the dark ages of blurry flip-phone images. Phones these days can take pictures professional enough to be screened in theaters or advertised in subway stops. And manufacturers are always looking to get an edge on the competition.

Best Linux distros for small businesses in 2018

Filed under

Running a small business is no easy task. The last thing you need is extra complexity in your IT infrastructure – so why turn to Linux?

Well, it could (if you're lucky) actually turn out to be a less complex choice for many tasks, depending on the distribution you select. And, critically, Linux is free; at least if you don't figure in support costs. That's an overhead ticked off the list.

  • Canonical Releases Spectre/Meltdown Patches for Ubuntu 17.10 for Raspberry Pi 2

    Canonical published two security advisories on Thursday to announce the availability of Spectre mitigations for the ARM64 (AArch64) hardware architecture on its Ubuntu 17.10 and Ubuntu 16.04.4 LTS systems.

    In January, Canonical released several kernel updates for Ubuntu 17.10 (Artful Aardvark) and other supported Ubuntu releases with software mitigations against the Spectre and Meltdown security vulnerabilities. These patches were first released for 64-bit (amd64) architectures, and then for 32-bit (i386), PPC64el, and s390x systems.

    Today, the company announced the availability of new kernel updates that address both the Meltdown and Spectre security vulnerabilities for the ARM64 (AArch64) hardware architecture, patching the Raspberry Pi 2 kernel for Ubuntu 17.10, as well as its derivatives.

  • Oracle Patches Spectre for Red Hat

    The Red Hat community has patiently awaited a retpoline kernel implementation that remediates CVE-2017-5715 (Spectre v2) and closes all Meltdown and Spectre vulnerabilities that have captured headlines this year.

    Red Hat's initial fixes rely upon microcode updates for v2 remediation, a decision that leaves the vast majority of AMD64-capable processors in an exploitable state. Intel's new microcode has proven especially problematic; it performs badly and the January 2018 versions were plagued with stability issues that crashed many systems. It is a poor solution to a pressing problem.

  • ​Meet the Scarlett Johansson PostgreSQL malware attack

    t's not the first time an image has been used to give a victim malware, but it may be the first time it's been used so narrowly. According to the security firm Imperva, their StickyDB database management system (DBMS) honeypot has uncovered an attack that places malware, which cryptomines Monero, on PostgreSQL DBMS servers. Its attack vector? An image of Hollywood star Scarlett Johansson.

    Now, you might ask, "How many PostgreSQL DBMS servers are out there on the internet to be attacked?" The answer: "More than you'd expect." A Shodan search revealed almost 710,000 PostgreSQL servers ready to be hacked. It appears there are so many of them because it's way too easy, especially on Amazon Web Services (AWS), to set up PostgreSQL servers without security.

  • This Black Box Can ‘Unlock Your iPhone’ For Cops; Images Leaked

    The debate whether law enforcement agencies should be given exclusive access to iOS-powered Apple devices started when the FBI was unable to unlock San Bernardino shooter’s iPhone. Eventually, FBI found other ways to get inside Apple’s secured digital fortress, through an Israel-based company called Cellebrite.

    In the latest news, we have come across about a new iPhone unlocking device called GrayKey that can be used by law enforcement guys to harvest passcode of an iPhone and other iOS-powered devices such as iPads and iPods.

  • Development Versions of Oracle Linux UEK now available on GitHub

    The source for UEK has always been available at, as a git repository with full git history. Starting now, we'll also be posting the UEK source on By doing so, we intend to increase the visibility for our work and to make it even easier for people to access the source for UEK. We will also use this repository for working with developers at partner companies and in the Linux community. The repository contains the source for the Unbreakable Enterprise Kernel including a small number of Oracle additions which have not yet been accepted into the mainline Linux kernel source tree.

    The Unbreakable Enterprise Kernel (UEK) is a Linux kernel built by Oracle and supported via Oracle Linux support. Its focus is performance, stability, and minimal backports by tracking the mainline source code as closely as is practical. UEK is well-tested and used to run Oracle's Engineered Systems, Oracle Cloud Infrastructure, and large enterprise deployments for Oracle customers.

  • Defining the Spectrum of Cloud Deployment Technologies

    “Cloud computing” has been a catch-all phrase over the past decade to describe anything that’s a shift away from hardware servers. However, the term has become nebulous in recent times with the growing diversity in how many different ways you can leverage the cloud.

    We’ve come far from a simplistic separation between on-premises and cloud. Today, it’s about on-premises versus a range of different cloud options. Indeed, the cloud can be a confusing place for newcomers and veterans alike, with new options cropping up every few months, and the landscape always shifting towards the newer and better.

    But how do you choose between good, better and best? Let’s compare the various cloud deployment technologies available today and find the common ground and what separates them from each other.

Software: Goto, Dry, QEMU, GStreamer

  • Goto – Quickly Navigate to Aliased Directories with Auto-Completion Support
    In a recent article, we talked about Gogo – a tool to create shortcuts for long paths in a Linux shell. Although gogo is a great way to bookmark your favorite directories inside a shell, however, it has one major limitation; it lacks an auto-completion feature. Because of the above reason, we went all out to find a similar utility with auto-completion support – where the shell can prompt with suggestions of the available aliases (shortcuts to long and complicated paths) and luckily, after crawling through Github, we discovered Goto.
  • Dry – An Interactive CLI Manager For Docker Containers
    Docker is a software that allows operating-system-level virtualization also known as containerization. It uses the resource isolation features of the Linux kernel such as cgroups and kernel namespaces, and others to allows independent containers to run within a single Linux instance. Docker provides a way to run applications securely isolated in a container, packaged with all its dependencies and libraries.

  • The Internet Archive Just Uploaded a Bunch of Playable, Classic Handheld Games
    The non-profit Internet Archive is perhaps best known for its Wayback Machine that takes snap shots of web sites so you can see what they looked like in the past. However, it also has a robust side project where it emulates and uploads old, outdated games that aren’t being maintained anymore. Recently, the organization added a slew of a unique kind of game that’s passed into memory: handheld LCD electronic games. The games–like Mortal Kombat, depicted above–used special LCD screens with preset patterns. They could only display the exact images in the exact place that they were specified for. This meant the graphics were incredibly limited and each unit could only play the one game it was designed to play. A Game Boy, this was not.
  • Internet Archive emulator brings dozens of handheld games back from obscurity
    Over the weekend, the Internet Archive announced it was offering a new series of emulators. This time, they’re designed to mimic one of gaming’s most obscure artifacts — handheld games. When I say a “handheld game,” I don’t mean the Game Boy or the PSP — those are handheld consoles. These are single-game handheld or tabletop devices that look and feel more like toys. The collection includes the very old, mostly-forgotten games sold in mini-handhelds from the 80s onward.
