8 of the Best IoT Projects Using Arduino

Filed under
Hardware

If you’re an electronics hobbyist, chances are you’ve heard of the Arduino. It’s a tiny computer that you can use to do surprisingly complex things. It also happens to be behind a fair number of Internet of Things projects.

While some people reach a for Raspberry Pi or something even more powerful, an Arduino or Arduino Uno might be all you need. We’ve put together a list of IoT projects that prove this to be true.

OSS
  • Announcing the Second Annual CopyleftConf!

    Last year's event was the first ever CopyleftConf. It was great! We have some videos up and more are coming. Also, our call for proposals is open now, through the end of the month -- we'd love to hear from you.

    The response was really positive and we're looking forward to putting on a fantastic 2020 event. Because last year's event was so well attended, we've gotten a larger venue for this year.

    Participants from throughout the copyleft world ? developers, strategists, enforcement organizations, scholars and critics ? will be welcomed for an in-depth, high bandwidth, and expert-level discussion about the day-to-day details of using copyleft licensing, obstacles facing copyleft and the future of copyleft as a strategy to advance and defend software freedom for users and developers around the world.

  • Nine more videos from the LibreOffice Conference 2019

    Yes, we’ve uploaded some more presentations from the recent LibreOffice Conference 2019 in Almeria, Spain. Many of these cover interoperability between LibreOffice and other office software.

  • Contributor Summit San Diego Schedule Announced!

    There are many great sessions planned for the Contributor Summit, spread across five rooms of current contributor content in addition to the new contributor workshops. Since this is an upstream contributor summit and we don’t often meet, being a globally distributed team, most of these sessions are discussions or hands-on labs, not just presentations. We want folks to learn and have a good time meeting their OSS teammates.

    Unconference tracks are returning from last year with sessions to be chosen Monday morning. These are ideal for the latest hot topics and specific discussions that contributors want to have. In previous years, we’ve covered flaky tests, cluster lifecycle, KEPs (Kubernetes Enhancement Proposals), mentoring, security, and more.

Games: Pine, Playing with Godot and Valve's ACO Work

  • Open-world action adventure 'Pine' where humans are not top of the food chain is now available

    Pine certainly looks good, a proper open-world action adventure with a story depicting humans who never reached the top of the food chain. It just release with Linux support today.

    Note: Both the publisher and GOG sent a copy for us.

  • Playing with Godot

    I guess it is quite common to start the path towards programming by making games. I started with a simple guess the number on my dad?s zx81 back in the day. He must have written most of it, but I felt proud of the result, so I will claim that it was mine.

    I?ve experimented with various ways to get my kids into programming. Everything from board games, online resources, scratch, building shitty robots, and so on. They get it, but it is hard to move on from the basics to being able to start from a clean sheet of paper and create something.

    During the summer, I decided to look into the various options and tried using Unity and Godot. After a couple of experiments, I settled on using Godot. Partly because of its open nature, but also because as a tool, it does the job I need it to do just as well as Unity.

  • Valve's Radeon "ACO" Vulkan Compiler Back-End Now Supports Navi

    The promising ACO compiler back-end for the Radeon "RADV" Vulkan driver now has support for GFX10/Navi graphics!

    ACO was recently merged into Mesa 19.3 for this Valve-funded, gaming-focused Vulkan shader compiler back-end for RADV. But up until now it has only supported GFX8 and GFX9 hardware while now initial Navi/GFX10 support has been merged. ACO ultimately aims to deliver better performance over the existing back-end while also more quickly compiling shaders to help with game load times.

  • Modern continuous integration/continuous delivery (CI/CD) pipeline for traditional provisioning: Your questions answered (Part 1)

    During a recent webinar titled, “Modern continuous integration/continuous delivery (CI/CD) pipeline for traditional provisioning,” we received a lot of interest and many questions regarding the topic. Some of the questions were coming in at a very rapid rate and we were not able to address them all. As a followup to our webinar, we have decided to put the answers to those questions into this blog post. The questions are listed below.

  • Red Hat Ceph object store on Dell EMC servers (Part 1)

    Organizations are increasingly being tasked with managing billions of files and tens to hundreds of petabytes of data. Object storage is well suited to these challenges, both in the public cloud and on-premise. Organizations need to understand how to best configure and deploy software, hardware, and network components to serve a diverse range of data intensive workloads.

    This blog series details how to build robust object storage infrastructure using a combination of Red Hat Ceph Storage coupled with Dell EMC storage servers and networking. Both large-object and small-object synthetic workloads were applied to the test system and the results subjected to performance analysis. Testing also evaluated the ability of the system under test to scale beyond a billion objects.

  • Why Linux Developers Should Reconsider IBM Mainframes

    When mainframes were mainstream, many software professionals in the industry today were not even born yet. Mainframe computers have an extensive history, which makes it tempting to call them old, but today’s mainframes are extremely mature, fast, reliable and powerful. In fact, they are critical to the modern economy: Top airlines, banks, insurance companies and health care corporations rely on mainframe computing.

    One of the organizations keeping this technology with the times is IBM, with its IBM Z family of mainframe computers. Some of these mainframes—like the 31-bit s390 and, later, the 64-bit s390x architecture—were originally designed and built in the 1960s, and they have continued to evolve and modernize.

    “IBM still sells a lot of these even today,” said Elizabeth K. Joseph, a seasoned open source advocate who recently joined IBM as the developer advocate for its Z architectures. These machines run operating systems including z/OS, z/VM, z/VSE and z/TPF, as well as Linux-based distributions like Red Hat Enterprise Linux and SUSE Linux Enterprise Server.

  • Fedora localization platform migrates to Weblate

    Fedora Project provides an operating system that is used in a wide variety of languages and cultures. To make it easy for non-native English speakers to use Fedora, significant effort is made to translate the user interfaces, websites and other materials.

    Part of this work is done in the Fedora translation platform, which will migrate to Weblate in the coming months.

    This migration was mandatory as development and maintenance of Zanata — the previous translation platform — ceased in 2018.

    There are a number of translation platforms available, but having a translation platform that is open source, answering Fedora Project’s needs, and likely to be long-lived are key considerations in choosing Weblate. Most other translation platforms being closed source or lacking features.

  • F30-20191009 updated Live Isos released

    The Fedora Respins SIG is pleased to announce the latest release of Updated F30-20190904 Live ISOs, carrying the 5.2.18-200 kernel.

    This set of updated isos will save considerable amounts of updates after install. ((for new installs.)(New installs of Workstation have 1.2GB of updates)).

    A huge thank you goes out to irc nicks dowdle, Southern-Gentleman for testing these iso.

In a forum, I often read the debate between the use of several types of package formats on Linux. In Ubuntu we know a variety of applications that are packaged in various packages. Examples are Flatpak, Appimage, Snap, Apt and others.

Sometimes, one user and another have different opinions when choosing a package. An example is in my post about the advantages of appimage. There are some comments about this package. There are pros and cons to this package. All returned to user needs. We cannot generalize the needs and choices of users who choose certain packages.

IDAD 2019: Join us on October 12th, and use this special dust jacket to uphold the right to read

Filed under
GNU

Each year we stage the International Day Against DRM (IDAD) to help others learn about the dangers of Digital Restrictions Management (DRM). For this year's IDAD on October 12th, we are focusing in particular on the increasing and disturbing amount of DRM present in ebooks and other online educational materials. Having so thoroughly invaded our leisure time, the digital infection known as DRM should not be allowed to spread into the classroom. Joining us in the fight for IDAD 2019 are the Electronic Frontier Foundation, Creative Commons, and The Document Foundation, among ten other participating organizations we are privileged to have standing with us in the fight against DRM.

In a bid to become the "Netflix of textbooks," and like many other publishers, Pearson is doing the opposite of what anyone committed to education should do: severely restricting a student's access to the materials they need for their courses through arbitrary page limits, "rented" books that disappear, and many which require a constant Internet connection.

Publishers like Pearson should not be allowed to decide the rigidly specific conditions under which a student can learn. No book should spy on your reading habits or simply "disappear" after you have had it for too long. In the digital age, it is unacceptable for a publisher to impose the same principles of scarcity that would apply to a physical product to a digital file. The computing revolution was caused by files being shared, not merely rented. Imposing these limitations on digital media is an attack on user freedom, no matter how much corporate PR may spin the story. It's our aim to let the world know that we support the rights of readers. You could say that for IDAD 2019, Defective by Design has you covered.

Intrinsyc announced a tiny “Open-Q 845 uSOM” and development kit that runs Android 9 or Yocto Linux on the octa-core Snapdragon 845. The module offers up to 6GB LPDDR4 and 64GB flash plus a WiFi/BT module.

In Feb. 2018 in conjunction with the launch of Qualcomm’s high-end, AI-enabled Snapdragon 845 (SDA845) SoC, Intrinsyc announced an Open-Q 845 HDK for the SoC aimed primarily at mobile phone developers. The Open-Q 845 comprised a Mini-ITX board with the Snapdragon 845 delivered via a compute module, but we never saw a separate SOM offering until now. The new Open-Q 845 uSOM is a 50 x 25mm mini-module like Intrinsyc’s Snapdragon 820-based Open-Q 820 µSOM. It’s supported by a Mini-ITX form-factor Open-Q 845 μSOM Development Kit, which is similar due to ship by the end of the year.

Austrumi Linux Has Great Potential if You Speak Its Language

Filed under
Linux
Reviews

This distro needs only limited system resources. Requirements include an Intel-compatible Pentium 2 processor or later and at least 512 MB of RAM. You can stretch this minimal memory level by running the "boot:nocache" option if the computer has less than 512 MB RAM.

No hard drive is needed, but you can find in the system menu an installation tool to place Austrumi Linux on the hard drive or a bootable USB drive. You also can run a live session directly from a bootable DVD if your system has an optical drive.

Other than the lack of adequate English language support within this distro, the only other significant design weakness is the lack of persistent memory if you run the OS without a hard drive installation. This means you can not save personal data and system configurations for your applications.

You can use a USB drive or cloud storage to save personal data. If you use Austrumi Linux as a portable OS, those two storage solutions will be in play anyway.

Austrumi is clearly not targeting non-European users. If developers fixed the language support for non-Latvian speakers, it could be much more convenient to use. Expanding support for other global regions is a critical need for this otherwise very handy performer.

Google Helps With Linux Scheduling With SchedViz

Filed under
Linux
Google

Google has just open sourced a tool that lets you visualize how your program is being treated under Linux scheduling. The idea is that you can use SchedViz to tune the system.

We all know the best scheduling algorithm to use - my program runs, everything else is suspended. Effective, but not cooperative. To achieve the same result while allowing other programs a chance to use the CPU we need to tune, and perhaps even select, the scheduling algorithm.

The problem is that the basic Linux tools to do the job are lacking and what generally happens is that you guess what might be best. In a modern system such a guess is unlikely to be correct because there are too many variables. Each thread has a priority and these interact under the scheduling policy. It can make a difference which core a thread is assigned to and changing cores is something best avoided.

OBS Studio is an open source video recorder and streaming app for Windows, Linux and macOS

Filed under
OSS

OBS Studio aka Open Broadcaster Software Studio is very popular among YouTube users. You can use it to broadcast gameplay streams live or use it to record videos (which you may then upload to YouTube or other video hosting sites). Want to set up a camera and mic to record content for your vlog? You can do that too.

This is one of those rare applications that is user-friendly on the one hand but still advanced enough to deliver the options that advanced users require. That being said, we're going to take a look at the basic usage of the program, the recording of on-screen content.

OBS Studio is a cross-platform program that is available for Windows, Mac OS X and Linux.

Tiny Rock Pi S and NanoPi Neo2 Black boards debut

Filed under
Linux

Radxa has opened $9.90 pre-orders for its tiny “Rock Pi S” SBC, which runs Linux on a quad -A35 RK3308. Meanwhile, FriendlyElec will soon ship a “NanoPi Neo2 Black” spin of the 40 x 40mm, Allwinner H5-based NanoPi Neo2 that adds eMMC, but reduces GPIO.

Over the last year, the focus of the community-backed Linux hacker board scene has shifted from tiny, power-sipping SBCs for IoT to more muscular, often AI-enabled boards selling for $50 to $100 built around processors such as the RK3399 and RK3399 Pro and Amlogic S922x and Amlogic A311D. But tiny boards are back with the pre-release launch of Radxa’s previously teased, 43.2 x 43.2mm Rock Pi S and the eminent release of a new 40 x 40mm NanoPi Neo2 LTS variant called the NanoPi Neo2 Black (see farther below).

  • Collapse OS is a Special Operating System for the Post-Apocalyptic Future

    As reported by Motherboard, there’s a new open-source operating system that is currently under heavy development, and it looks like it will soon be ready for a very dire scenario. Its creator, Virgil Dupras, is a person who believes there’s a good chance that by 2030, the world will have collapsed. The software developer isn’t absolutely certain about this, but he believes that the chances of the scenario are high enough to justify the development of a post-apocalyptic operating system, called “Collapse OS”.

    So, what would the ideal scavenger’s operating system be like? The simple answer to this would be “one that can run on virtually anything”. If there is one system out there that can run on almost any hardware, this is the Debian GNU/Linux distribution. Collapse OS is taking things a lot further, being able to run on microcontrollers such as the ubiquitous Z80 microprocessor. Dupras considered what piece of hardware would be the easiest to find in a post-apocalyptic world, and Z80 came as the definitive answer. This 8-bit microprocessor is in cash registers, computers, music instruments, calculators, and virtually anything electronic.

  • PostgreSQL considers seccomp() filters

    A discussion on the pgsql-hackers mailing list at the end of August is another reminder that the suitability of seccomp() filters is likely more narrow than was hoped. Applying filters to the PostgreSQL database is difficult for a number of reasons and the benefit for the project and its users is not entirely clear. The discussion highlights the tradeoffs inherent in adding system-call filtering to a complex software suite; it may help crystallize the thinking of other projects that are also looking at supporting seccomp() filters.

    Joe Conway raised the idea in an RFC patch posting. It added a way to filter system calls in the main postmaster process and, with a separate system-call list, in the per-session backends. It also showed how to generate the list of system calls that are being used by PostgreSQL under various workloads, such as the test targets in the Makefile or by running a specific application. Information on the system calls made is logged by the audit subsystem; those logs are then processed to produce the list. Once there is confidence that the list is complete—which may be a sticking point—the remaining system calls could be blocked so that executing them would cause an error.

    But Peter Eisentraut was concerned that the list is going to be incomplete due to the "fantastic test coverage" needed to generate it and that it will require constant maintenance to keep up with GNU C Library (glibc) and other changes. Beyond that, PostgreSQL extensions will need their own lists of allowed system calls. Conway seems to see the support as something that those interested will maintain for themselves, rather than having a list that the project will distribute. "Perhaps most people never use this, but when needed (and increasingly will be required) it is available."

  • mjbots quad A0: October 2019 Roadmap

    My last video gave an overview of what I’ve accomplished over the past year. Now, let me talk about what I’m planning to work on going forward:

Linux security hole: Much sudo about nothing

There's a lot of hubbub out there now about a security hole in the Unix/Linux family's sudo command. Sudo is the command, which enables normal users to run commands as if they were the root user, aka the system administrator. While this sudo security vulnerability is a real problem and needs patching, it's not nearly as bad as some people make it out to be. At first glance the problem looks like a bad one. With it, a user who is allowed to use sudo to run commands as any other user, except root, can still use it to run root commands. For this to happen, several things must be set up just wrong. First the sudo user group must give a user the right to use sudo but doesn't give the privilege of using it to run root commands. That can happen when you want a user to have the right to run specific commands that they wouldn't normally be able to use. Next, sudo must be configured to allow a user to run commands as an arbitrary user via the ALL keyword in a Runas specification. Read more

Ubuntu 19.10 (Eoan Ermine) Enters Final Freeze Ahead of October 17th Release

As of October 10th, the Ubuntu 19.10 release is officially in Final Freeze, the last step of its development stage, which means that only release critical bugs affecting the ISO images or the installers will be accepted in the archives. Release Candidate images are also now available for testing to ensure an uneventful and smooth release. "We will shut down cronjobs and spin some RC images late Friday or early Saturday once the archive and proposed-migration have settled a bit, and we expect everyone with a vested interest in a flavour (or two) and a few spare hours here and there to get to testing to make sure we have another uneventful release next week," said Adam Conrad.

Games: The Universim, POSTAL 4: No Regerts, RPCS3, Shadow of the Tomb Raider, Games Archive and X-Plane

  • City building god sim 'The Universim' will now let you launch rockets with satellites into orbit

    The Universim is slowly turning into a city building god game truly worth playing, with the Sky High update now available expanding the game into planetary orbit. Being able to actually launch things into space is a stepping stone towards visiting other planets. Currently, the Cosmodrome will allow you to send up Defence Satellites that will enable ground to air defences for your Defence Towers. So now you have a reasonable chance to take down meteors and other threats from space.

  • POSTAL 4: No Regerts released into Early Access, Linux version likely in future

    Running With Scissors are back, with a surprise release of POSTAL 4: No Regerts on Steam and a Linux version is looking likely in future. Naturally, someone posted on Steam to ask about the possibility of Linux support. This is something that happens a lot but here it's a bit different. RWS already supported Linux with multiple previous Postal releases.

  • PlayStation 3 emulator RPCS3 is coming along quickly with their August progress report up

    Delayed as usual due to the progress reports being done by contributors, the team working on the PlayStation 3 emulator RPCS3 have another post up to show off more incredible progress. To start with, they have again changed how they list what games are playable and not with the removal of games that won't work due to servers being shut down. They said even if RPCS3 becomes 100% complete, they wouldn't work unless someone accurately emulated and hosted servers for them. With that in mind, they also did a lot of testing of games that previously only went in-game to see how many are now properly playable. Thanks to all the testing, the Playable category has jumped up to 1,426 titles!

  • Shadow of the Tomb Raider Definitive Edition arrives on Linux on November 5th

    Feral Interactive have finally confirmed the Linux release date for Shadow of the Tomb Raider after announcing it for Linux back in November last year. They've said today it will officially release as "Shadow of the Tomb Raider Definitive Edition" on November 5th! Looking around at dates, technically this is the earliest we've seen any of the newer Tomb Raider series arrive on Linux. The first Tomb Raider came to Linux in 2016 after an original 2013 release, with Rise of the Tomb Raider arriving on Linux 2018 after an original 2016 release and we get the final game in the reboot trilogy next month!
