Raspberry Pi 101 – An Introduction to the Raspberry Pi GPIO

Filed under
Linux

An important feature of the Raspberry Pi is the row of GPIO pins, where GPIO stands for general purpose input/output. It will allow us to communicate between Pi and the outside world. We have 40pins on Pi, we count these pins from left to right out of which seventeen pins are GPIO pins. Different pins are used for the different functions and can be connected to a number of external peripherals such as buttons, lights, relays, sensors, etc.

Containers, the GPL, and copyleft: No reason for concern

Filed under
Linux
OSS

Though open source is thoroughly mainstream, new software technologies and old technologies that get newly popularized sometimes inspire hand-wringing about open source licenses. Most often the concern is about the GNU General Public License (GPL), and specifically the scope of its copyleft requirement, which is often described (somewhat misleadingly) as the GPL’s derivative work issue.

One imperfect way of framing the question is whether GPL-licensed code, when combined in some sense with proprietary code, forms a single modified work such that the proprietary code could be interpreted as being subject to the terms of the GPL. While we haven’t yet seen much of that concern directed to Linux containers, we expect more questions to be raised as adoption of containers continues to grow. But it’s fairly straightforward to show that containers do not raise new or concerning GPL scope issues.

Get ready to use Linux containers

Filed under
Server

One of the most exciting things to happen in the Linux world in the past few years is the emergence of containers — self-contained Linux environments that live inside another OS and provide a way to package and isolate applications.

They're not quite virtual systems, since they rely on the host OS to operate, nor are they simply applications. Dan Walsh from Red Hat has said that on Linux, "everything is a container," reminding me of the days when people claimed that everything on Unix was a file. But the vision has less to do with the guts of the OS and more to do with explaining how containers work and how they are different than virtual systems in some very interesting and important ways.

Samsung unveils 860 PRO and EVO SATA SSDs with improved Linux compatibility

Filed under
Linux

If you haven’t yet upgraded your operating system drive from a mechanical hard disk to a solid state drive, you are really missing out. Prices have dropped dramatically over the years, while at the same time, reliability has improved. Swapping an HDD for an SSD can be very easy too, thanks to cloning software that often comes with the drive.

Before you buy some random SSD, please know that they are not all the same. True, SATA models largely have equal speeds these days, but the brand really matters from a reliability standpoint. If you want a dependable solid state drive for your data, you should take a look at Samsung. Its offerings are top notch, and today the company launches its newest SATA models -- the 860 PRO and EVO.

DLP platform for 3D vision teams up with Raspberry Pi

Filed under
Linux

Keynote Photonics has launched a $499 “LC3000G2-Pi” light-steering and 3D vision add-on for the Raspberry Pi, and will soon ship a “LC3000G2-PRO,” which similarly offers TI’s DLP3000 chipset, but runs TI Lightcrafter APIs on its own DM365-based Linux board.

Texas Instruments’ Linux-driven DLP (digital light processing) technology was originally launched as a projection technology, and is still primarily used for projection applications ranging from pico projectors you can plug into your laptop to advanced digital cinema projection machines. Yet, the technology is increasing moving into machine vision.

  • Firefox’s continued Quantum transformation—more multithreading, tracking protection

    Firefox 58, out today, continues to deliver Project Quantum, Mozilla's far-reaching modernization effort that's boosting the browser's performance, security, and maintainability. The initiative allows Firefox to take better advantage of modern multicore processors and makes the browser better suited to the demands of today's Web applications.

  • WebRender capture infrastructure

    For over a year now, I’ve been hacking on WebRender. It was born in Servo as an experimental way to batch the painting and compositing of the web content on GPU. Today it’s a solid piece of engineering that’s going to mainline Firefox as the next big Rust-written component within the Quantum project. You can read more about WebRender on our team’s blog as well as this wonderfully illustrated article by Lin Clark.

  • The Different Types of Privacy Protection

    Many of your favorite sites keep track of what you do online. They may do it to understand if you’re interested in a particular article, item or activity. They may do it to make your experience of their site easier. They may also track you so they can try to sell you things.

    Online ads can be customized on the fly based on what you do. Been searching for a new pair of Chucks? Mega Shoe Company has a great deal for you. To serve those custom ads at just the right time, the shoe company needs to know where you go online. Is that bad? Some argue that customized (targeted) ads are much better than traditional billboards or radio spots. At least with targeted ads, there’s a good chance you’ve been looking for what they’re selling. But you may not want companies following you around the web.

  • Introducing the MDN Product Advisory Board: actions and impressions from our first meeting

    On January 11th, 2018, Mozilla held the first in-person meeting of the MDN Product Advisory Board (PAB) in London. The goal of the MDN Product Advisory Board, in collaboration with Microsoft, Google, and other industry leaders, is to provide guidance that helps MDN be the best reference for web developers.

    To that end, I’m pleased to announce that the web platform consultancy Bocoup, represented by Rick Waldron, will be joining the MDN Product Advisory Board starting in February. Bocoup brings a practitioner’s perspective to the the standards process and participates in a wide range of open source projects. Rick has actively contributed to MDN since May of 2011, writing documentation, reviewing contributions, and participating in the maintenance of the JavaScript Reference sub-articles. He’s written proposals and specifications for new JavaScript APIs and syntax, participated in ECMAScript® 2015, 2016, 2017 Language Specifications, and represents Bocoup at ECMA TC39 meetings. I’m very excited Rick will be adding his considerable industry knowledge and JavaScript focus to the board and look forward to him joining our next meeting.

Security Leftovers

Security
  • Security updates for Tuesday
  • Initial Retpoline Support Added To LLVM For Spectre v2 Mitigation

    The LLVM code has been merged to mainline for the Retpoline x86 mitigation technique for Spectre Variant 2. This will be back-ported to LLVM 6.0 and also LLVM 5.0 with an immediate point release expected to get this patched compiler out in the wild.

    The compiler-side work -- similar to GCC's Retpoline code -- is to avoid generating code where an indirect branch could have its prediction poisoned by a rogue actor. The Retpoline support uses indirect calls in a non-speculatable way.

  • Teen Hacker Who Social Engineered His Way Into Top-Level US Government Officials' Accounts Pleads Guilty To Ten Charges

    The teenage hacker who tore CIA director John Brennan a new AOL-hole is awaiting sentencing in the UK. Kane Gamble, the apparent founder of hacker collective Crackas With Attitude, was able to access classified documents Brennan has forwarded to his personal email account by posing as a Verizon tech. Social engineering is still the best hacking tool. It's something anyone anywhere can do. If you do it well, a whole host of supposedly-secured information can be had, thanks to multiple entities relying on the same personal identifiers to "verify" the social engineer they're talking to is the person who owns accounts they're granting access to.

    Despite claiming he was motivated by American injustices perpetrated around the world (Palestine is namechecked in the teen's multiple mini-manifestos), a lot of what Gamble participated in was plain, old fashioned harassment.

  • The Guardian view on cyberwar: an urgent problem [Ed: Lists several attacks by Microsoft Windows (but names neither)]

    The first known, and perhaps the most successful of these, was the joint US/Israeli Stuxnet attack on the Iranian nuclear programme in 2009. Since then there has been increasing evidence of attacks of this sort by Russia – against Estonia in 2009, and then against Ukraine, where tens of thousands of attacks on everything from power supplies to voting machines have opened an under-reported front in an under-reported war. Across the Baltic, the Swedish government has just announced a beefed-up programme of civil defence, of which the most substantial part will be an attempt to protect its software and networks from attacks. Meanwhile, North Korean state hackers are blamed by western intelligence services for the WannaCry ransomware attacks which last year shut down several NHS hospitals in the UK. Persistent reports suggest the US has interfered in this way with North Korea’s nuclear missile programme.

  • mesa 18.0-0-rc1

    The first release candidate for Mesa 18.0.0 is now available.

    The plan is to have one release candidate every Friday, until the anticipated

    The expectation is that the 17.3 branch will remain alive with bi-weekly
    releases until the 18.0.1 release.

    NOTE: Building the SWR with LLVM 3.9 is currently not possible. Please use
    newer LLVM version until the issue is resolved.

    Here are the people which helped shape the current release.

  • Mesa 18.0 Now Under Feature Freeze With 18.0-RC1 Premiere

    Feature development on Mesa 18.0 has now ended with the release today of 18.0-RC1 following the code-base being branched.

    Emil Velikov of Collabora just announced the availability of Mesa 18.0-RC1. As usual, he's planning on weekly release candidates until the 18.0.0 stable release is ready to ship. Velikov tentatively expects to ship Mesa 18.0.0 around 9 February, but as we know from past releases, it might end up slipping by some days.

Using Dual 4K Monitors Stacked With GNOME

Filed under
GNOME

The setup for my main production system that is still on Fedora Workstation 26 with GNOME Shell 3.24.3 has been working out fine. The two displays are the ASUS MG28UQ monitors that work out well on their own and do work with AMDGPU FreeSync on Linux. A GeForce GTX 1050 Ti is enough to power the dual 3840 x 2160 displays for desktop tasks mostly limited to many terminals, Firefox, Chrome, Thunderbird, and other GNOME desktop applications. Certainly that lower-end Pascal GPU isn't fast enough for 4K gaming, but it's not like I have the time for any gaming and for a purely desktop system it's working out fine paired with the 387.34 proprietary driver on Fedora 26 paired with Linux 4.14.

  • Become a mechanic and save the world in Iconoclasts, now on Linux

    It's not often I enjoy a game as thoroughly as Iconoclasts, there's so much about it to love it's something I will remember for a long time.

    Disclosure: Key provided by the developer and GOG. Also, GOG links are affiliate links.

    Iconoclasts took a long time to make, the developer said it took seven years of full time development to make it happen, the end result is something quite remarkable. A game that would have fit rather nicely on the classic Sega Mega Drive, yet it feels fresh, fun and absolutely full of life.

    The final release of Godot 3.0 is getting closer and closer! We had a first Release Candidate (RC) last week, quite stable already but with some remaining blockers and late regressions.

    After a week of bugfixing with a tight control of what gets merged and what must wait for the 3.1 development cycle, we should now have a pretty good RC 2.

  • Valve Releases Big SteamOS Update with Linux Kernel 4.14, New Nvidia/AMD Drivers

    Valve released today a new stable update of its Debian-based SteamOS gaming operating system that brings a new kernel version, new Nvidia and AMD drivers, and lots of up-to-date components.

    SteamOS 2.148 is now the newest stable release of the Linux-based operating system that ships pre-installed on Steam Machines. While it remains based on the Debian GNU/Linux 8 "Jessie" operating system series, SteamOS 2.148 is powered by the latest Linux 4.14.13 kernel, which includes patches for Spectre and Meltdown flaws.

    Additionally, SteamOS 2.148 includes new Nvidia, AMD, and Intel graphics drivers. It uses the Nvidia 387.22 proprietary graphics driver for Nvidia GPUs, as well as the open-source Mesa 17.2.4 graphics stack for AMD Radeon and Intel GPUs. Other than that, the update comes with better upgrade support.
