6 Industrial Touch-Panel Computers Based on the Raspberry Pi

Filed under
Linux

In the smart home, voice agents are increasingly replacing the smartphone touchscreen interface as the primary human-machine interface (HMI). Yet, in noisier industrial and retail IoT environments, touchscreens are usually the only choice. The industrial touch-panel computer market has been in full swing for over a decade. Touch-panel systems based on Linux, and to a lesser extent, Android, are gaining share from those that use the still widely used Windows Embedded, and over the past year, several Raspberry Pi based systems have reached market. Here we look at six RPi-based contenders.

Mozilla: Rust Compiler, Firefox Updates and Docker

Filed under
Moz/FF
  • The Rust compiler is getting faster

    As changes are made to the Rust compiler, a suite of benchmarks measuring compile time is run regularly on the development version. The data is viewable at http://perf.rust-lang.org. The default view is graphical, showing data from the past month.

  • These Weeks in Firefox: Issue 38
  • Scaling Firefox Development Workflows

    One of the central themes of my time at Mozilla has been my pursuit of making it easier to contribute to and hack on Firefox.

    I vividly remember my first day at Mozilla in 2011 when I went to build Firefox for the first time. I thought the entire experience - from obtaining the source code, installing build dependencies, building, running tests, submitting patches for review, etc was quite... lacking. When I asked others if they thought this was an issue, many rightfully identified problems (like the build system being slow). But there was a significant population who seemed to be naive and/or apathetic to the breadth of the user experience shortcomings. This is totally understandable: the scope of the problem is immense and various people don't have the perspective, are blinded/biased by personal experience, and/or don't have the product design or UX experience necessary to comprehend the problem.

  • Release of python-zstandard 0.9

    Zstandard is a highly tunable and therefore flexible compression algorithm with support for modern features such as multi-threaded compression and dictionaries. Its performance is remarkable and if you use it as a drop-in replacement for zlib, bzip2, or other common algorithms, you'll frequently see more than a doubling in performance.

  • Revisiting Using Docker

    When Docker was taking off like wildfire in 2013, I was caught up in the excitement like everyone else. I remember knowing of the existence of LXC and container technologies in Linux at the time. But Docker seemed to be the first open source tool to actually make that technology usable (a terrific example of how user experience matters).

    At Mozilla, Docker was adopted all around me and by me for various utilities. Taskcluster - Mozilla's task execution framework geared for running complex CI systems - adopted Docker as a mechanism to run processes in self-contained images. Various groups in Mozilla adopted Docker for running services in production. I adopted Docker for integration testing of complex systems.

Coverage From 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM)

Filed under
Linux
  • Is it time to remove ZONE_DMA?

    The DMA zone (ZONE_DMA) is a memory-management holdover from the distant past. Once upon a time, many devices (those on the ISA bus in particular) could only use 24 bits for DMA addresses, and were thus limited to the bottom 16MB of memory. Such devices are hard to find on contemporary computers. Luis Rodriguez scheduled the last memory-management-track session of the 2018 Linux Storage, Filesystem, and Memory-Management Summit to discuss whether the time has come to remove ZONE_DMA altogether.

  • Zone-lock and mmap_sem scalability

    The memory-management subsystem is a central point that handles all of the system's memory, so it is naturally subject to scalability problems as systems grow larger. Two sessions during the memory-management track of the 2018 Linux Storage, Filesystem, and Memory-Management Summit looked at specific contention points: the zone locks and the mmap_sem semaphore.

  • Hotplugging and poisoning

    Memory hotplugging is one of the least-loved areas of the memory-management subsystem; there are many use cases for it, but nobody has taken ownership of it. A similar situation exists for hardware page poisoning, a somewhat neglected mechanism for dealing with memory errors. At the 2018 Linux Storage, Filesystem, and Memory-Management summit, Michal Hocko and Mike Kravetz dedicated a pair of brief memory-management track sessions to problems that have been encountered in these subsystems, one of which seems more likely to get the attention it needs than the other.

  • Reworking page-table traversal

    A system's page tables are organized into a tree that is as many as five levels deep. In many ways those levels are all similar, but the kernel treats them all as being different, with the result that page-table manipulations include a fair amount of repetitive code. During the memory-management track of the 2018 Linux Storage, Filesystem, and Memory-Management Summit, Kirill Shutemov proposed reworking how page tables are maintained. The idea was popular, but the implementation is likely to be tricky.

  • get_user_pages() continued

    At a plenary session held relatively early during the 2018 Linux Storage, Filesystem, and Memory-Management Summit, the developers discussed a number of problems with the kernel's get_user_pages() interface. During the waning hours of LSFMM, a tired (but dedicated) set of developers convened again in the memory-management track to continue the discussion and try to push it toward a real solution.

    Jan Kara and Dan Williams scheduled the session to try to settle on a way to deal with the issues associated with get_user_pages() — in particular, the fact that code that has pinned pages in this way can modify those pages in ways that will surprise other users, such as filesystems. During the first session, Jérôme Glisse had suggested using the MMU notifier mechanism as a way to solve these problems. Rather than pin pages with get_user_pages(), kernel code could leave the pages unpinned and respond to notifications when the status of those pages changes. Kara said he had thought about the idea, and it seemed to make some sense.

  • XFS parent pointers

    At the 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM), Allison Henderson led a session to discuss an XFS feature she has been working on: parent pointers. These would be pointers stored in extended attributes (xattrs) that would allow various tools to reconstruct the path for a file from its inode. In XFS repair scenarios, that path will help with reconstruction as well as provide users with better information about where the problems lie.

  • Shared memory mappings for devices

    In a short filesystem-only discussion at the 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM), Jérôme Glisse wanted to talk about some (more) changes to support GPUs, FPGAs, and RDMA devices. In other talks at LSFMM, he discussed changes to struct page in support of these kinds of devices, but here he was looking to discuss other changes to support mapping a device's memory into multiple processes. It should be noted that I had a hard time following the discussion in this session, so there may be significant gaps in what follows.

  • A new API for mounting filesystems

    The mount() system call suffers from a number of different shortcomings that has led some to consider a different API. At last year's Linux Storage, Filesystem, and Memory-Management Summit (LSFMM), that someone was Miklos Szeredi, who led a session to discuss his ideas for a new filesystem mounting API. Since then, David Howells has been working with Szeredi and VFS maintainer Al Viro on this API; at the 2018 LSFMM, he presented that work.

    He began by noting some of the downsides of the current mounting API. For one thing, you can pass a data page to the mount() call, but it is limited to a single page; if too many options are needed, or simply options with too many long parameters, they won't fit. The error messages and information on what went wrong could be better. There are also filesystems that have a bug where an invalid option will fail the mount() call but leave the superblock in an inconsistent state due to earlier options having been applied. Several in the audience were quick to note that both ext4 and XFS had fixed the latter bug along the way, though there may still be filesystems that have that behavior.

  • Controlling block-I/O latency

    Chris Mason and Josef Bacik led a brief discussion on the block-I/O controller for control groups (cgroups) in the filesystem track at the 2018 Linux Storage, Filesystem, and Memory-Management Summit. Mostly they were just aiming to get feedback on the approach they have taken. They are trying to address the needs of their employer, Facebook, with regard to the latency of I/O operations.

    Mason said that the goal is to strictly control the latency of block I/O operations, but that the filesystems themselves have priority inversions that make that difficult. For Btrfs and XFS, they have patches to tag the I/O requests, which mostly deals with the problem. They have changes for ext4 as well, but those are not quite working yet.

  • A mapping layer for filesystems

    In a plenary session on the second day of the Linux Storage, Filesystem, and Memory-Management Summit (LSFMM), Dave Chinner described his ideas for a virtual block address-space layer. It would allow "space accounting to be shared and managed at various layers in the storage stack". One of the targets for this work is for filesystems on thin-provisioned devices, where the filesystem is larger than the storage devices holding it (and administrators are expected to add storage as needed); in current systems, running out of space causes huge problems for filesystems and users because the filesystem cannot communicate that error in a usable fashion.

    His talk is not about block devices, he said; it is about a layer that provides a managed logical-block address (LBA) space. It will allow user space to make fallocate() calls that truly reserve the space requested. Currently, a filesystem will tell a caller that the space was reserved even though the underlying block device may not actually have that space (or won't when user space goes to use it), as in a thin-provisioned scenario. He also said that he would not be talking about his ideas for a snapshottable subvolume for XFS that was the subject of his talk at linux.conf.au 2018.

  • Truth is More Important Than Harmony

    Today I did a very silly thing, because it was the right moment and the right audience…

    No, it probably wasn’t! But I figured it was probably as close as it would get to one. Of course it will brand me further as a troublemaker, but that’s not entirely fair– I really wasn’t the one who started the trouble.

    Devuan’s structure is clearly built on the bazaar– when they find something unofficial that can help Devuan more than hurt it, they just offer the opportunity to be official.

    This is based on observation and it may not be true as a solid rule, but it happened with Devuan-live (and it’s one the best moves Devuan made– it helped me to believe they can make timely, great decisions) and it appeared to be happening eventually with vdev (unfortunately abandoned by its author) and it appears to have happened with the now-official Devuan forum: https://devuan.org/

  • Ksnip And Flameshot: Qt5 Shutter Screenshot Tool Alternatives

    Shutter is a great application for taking screenshots in Linux, but it has only received bug fixes for years. The application continues to use Gtk+ 2 and doesn't seem to be getting anywhere as far as Gtk+ 3 is concerned.

    Furthermore, the Shutter image editor (which allows adding text, annotations, etc.) now requires installing old libraries to get it to work in recent Linux distributions.

    This article presents 2 Shutter alternatives for taking screenshots on Linux desktops, that are actively developed: Ksnip and Flameshot. Both applications use Qt 5.

    As a side note, I considered the following features to be required in order to compete with Shutter: the ability to upload an image directly from the screenshot tool to some image host, and support for drawing / annotations.

  • Building a DIY amp kit that's great for vinyl records

    About a week after I wrapped up my last article where I talked about needing another stage of amplification to take advantage of my new 0.4mV phono cartridge, all the remaining bits and pieces I had ordered online to build the Muffsy phono head amplifier kit arrived. I had the amplifier kit, the power supply kit, the back-panel kit (all from Muffsy), the case (from a very efficient supplier in China), the temperature-controlled soldering station, and the wall wart (from a very efficient supplier in California).

    I watched the entertaining "how to solder" videos linked on Muffsy's site and realized I needed a few more things—like the thin solder mentioned on those videos and some solder wick. So, on an unusually bright and sunny Saturday morning, I visited a local electronics supply store, picked up the last items, and started building.

    [...]

    I contacted "the person behind Muffsy," Håvard Skrodahl, with some questions. He responded very quickly, and we ended up having a most delightful conversation. Moreover, it turns out Håvard is a system administrator and does this "kit thing" as a side gig. We discussed (or maybe lamented) that "back in the good old days" it was possible to buy all sorts of electronics kits, from Heathkit, Dynaco, David Hafler, and others. Today, there are still audio kits available, but it seems to be of lesser interest. Too bad! I am very grateful to Håvard for open sourcing so much of his materials.

  • Summer of Code: Quick Update

    I noticed that my blog posting frequency is substantially higher than last year. For that reason I’ll try to keep this post shorter.

It can process incoming PubkeyElements (the published OpenPGP keys of other users) and create SigncryptElements which contain a signed and encrypted payload. On the receiving side it can also decrypt those messages and verify the signature.

    I’m still puzzled about why I’m unable to dump the keys I generate using pgpdump. David Hook from Bouncycastle used my code to generate a key and it worked flawlessly on his machine, so I’m stumped for an answer…

    I created a bug report about the issue on the pgpdump repository. I hope that we will get to the cause of the issue soon.

  • BCE Panel: Open Source Makes Telcos 'Nimble'

    Big Communications Event -- Open source can help telcos become "nimble," and shed their history of "wait and see," James Feger, CenturyLink VP of network virtualization, said here Tuesday at Light Reading's Big Communications Event (BCE).

    "The power of open source is it allows telcos to be more nimble, rather than the wait-and-see attitude we've traditionally been viewed with," CenturyLink Inc. (NYSE: CTL)'s Feger said, speaking on a panel about open source in telecom.

    Indeed, innovation rather than cost savings are the main reason to adopt open source, noted Csaba Kiss Kallo, head of connectivity, mobility and security portfolio at Vodafone Ireland. "'Free' is not the main reason we go after open source. The reason is agility -- the benefits you get from an ecosystem and development, those thousands of software developers who've put their knowledge together and developed something that can be used by everyone in the community," he said. (See Vodafone Prioritizes Automation as Efficiency Bolsters Margins.)

    This is the first device under The Zerocat Label to receive RYF certification. The Chipflasher enables users to flash devices such as laptops, allowing them to replace proprietary software with free software like Libreboot. While users are able to purchase RYF-certified laptops that already come with Libreboot pre-loaded, for the first time ever they are capable of freeing their own laptops using an RYF-certified device. The Zerocat Chipflasher board-edition-1 is now available for purchase as a limited edition at http://www.zerocat.org/shop-en.html. These first ten limited edition boards are signed by Kai Mertens, chief developer of The Zerocat Label, and will help to fund additional production and future development of RYF-certified devices.

    "The certification of the Zerocat Chipflasher is a big step forward for the Respects Your Freedom program. Replacing proprietary boot firmware is one of the first tasks for creating a laptop that meets RYF's criteria, and now anyone can do so for their own devices with a flasher that is itself RYF-certified," said the FSF's executive director, John Sullivan.

    An RYF-certified flashing device could also help to grow the number of laptops available via the RYF program.

    "When someone sets out to start their own business selling RYF-certified devices, they now have a piece of hardware they can trust to help them with that process. We hope to see even more laptops made available under the program, and having those laptops flashed with a freedom-respecting device will help to set those retailers on the right path from the start," said the FSF's licensing & compliance manager, Donald Robertson, III.

  • Searching Open Source Material in the Age of Information

    Intelligence analysts are thought to be commensurate experts in writing, research, and analysis, but does the next generation of analysts have the skills necessary to be successful in the intelligence field? One of the greatest challenges for an analyst today is that the amount of information—as well as the means in which it’s shared—is growing exponentially.

    Intelligence analysts must be able to gather, correlate, analyze, and evaluate information from a wide variety of sources. These sources can include law enforcement portals and databases, surveillance systems, intelligence networks (various disciplines), geographic information systems (GIS), and private data-mining databases (subscription-based).

  • Mir Is Running On Arch Linux; Mir Also Progressing With EGLStreams Support
    Prominent Mir developer Alan Griffiths of Canonical has published his latest weekly update on the status of this Linux display server that continues working on supporting Wayland clients. First up, via the UBports community, Mir is now working on Arch Linux after some basic changes and packaging work. So similar to Ubuntu and Fedora and others, it's now easy to run Mir on Arch Linux if so desired.
  • VK9 - Direct3D 9 Over Vulkan - Hits 26th Milestone
    It's been a wild week for the various Direct3D-over-Vulkan projects with VKD3D 1.0 being released for the initial Direct3D 12 over Vulkan bits from the ongoing work in the Wine project to DXVK continuing to get better at its D3D11-over-VLK support. There's also an update on the VK9 front.
  • Wine-Staging 3.9 Fixes D3D 10/11 Gaming Performance Regressions
    One day after the exciting Wine 3.9 update with VKD3D work and more, the Wine-Staging code has been updated against this latest development release. While since the revival of Wine-Staging earlier this year there has been more than 900 out-of-tree/experimental patches against this Wine branch, with Wine-Staging 3.9 that patch count comes in at 895 patches. It's great to see with more of the changes working their way into upstream Wine after being vetted while other patches are no longer relevant. Also decided this week is that Wine-Staging developers will rely upon the WineHQ bug infrastructure for handling the submission of new Wine-Staging patches so that the work is much easier to track by users/developers in seeing the status and background on proposed patches for the staging tree.

  • « The Microsoft Cyber Attack » : a German Documentary from the ARD on Relations Between Microsoft and Public Administration Now Available in English

    On February 19th, 2018, the German public broadcaster (ARD) aired a documentary on Microsoft relations with public administrations. Part of the inquiry is about the Open Bar agreement between Microsoft and the French ministry of Defense, including interviews of French Senator Joëlle Garriaud-Maylam, Leïla Miñano, a journalist, and Étienne Gonnu of April.

    The documentary is now available in English thanks to Deutsche Welle (DW), the German public international broadcaster, on its Youtube channel dedicated to documentaries : The Microsoft Cyber Attack. It should be noted that April considers itself as a Free software advocate, rather than open source, as the voice-over suggests.

  • VPNFilter UNIX Trojan – How to Remove It and Protect Your Network
    This article has been created to explain what exactly is the VPNFilter malware and how to secure your network against this massive infection by protecting your router as well as protecting your computers. A new malware, going by the name of VPNFilter has reportedly infected over 500 thousand router devices across most widely used brands such as Linksys, MikroTik, NETGEAR as well as TP-Link, mostly used in homes and offices. The cyber-sec researchers at Cisco Talos have reported that the threat is real and it is live, even thought the infected devices are under investigation at the moment. The malware reportedly has something to do with the BlackEnergy malware, which targeted multiple devices in Ukraine and Industrial Control Systems in the U.S.. If you want to learn more about the VPNFilter malware and learn how you can remove it from your network plus protect your network, we advise that you read this article.

  • Compliance is Not Synonymous With Security
    While the upcoming GDPR compliance deadline will mark an unprecedented milestone in security, it should also serve as a crucial reminder that compliance does not equal security. Along with the clear benefits to be gained from upholding the standards enforced by GDPR, PCI DSS, HIPAA, and other regulatory bodies often comes a shift toward a more compliance-centric security approach. But regardless of industry or regulatory body, achieving and maintaining compliance should never be the end goal of any security program. Here’s why:
  • Dialing up security for Docker containers
    Docker containers are a convenient way to run almost any service, but admins need to be aware of the need to address some important security issues. Container systems like Docker are a powerful tool for system administrators, but Docker poses some security issues you won't face with a conventional virtual machine (VM) environment. For example, containers have direct access to directories such as /proc, /dev, or /sys, which increases the risk of intrusion. This article offers some tips on how you can enhance the security of your Docker environment.

Programming: Fonts, Jupyter, and Open Source FPGAs

  • 11 Best Programming Fonts
    There are many posts and sites comparing fonts for programming and they are all amazing articles. So why I repeated the same subject here? Since I always found myself lost in dozens of fonts and could not finger out which one was best for me. So today I tried many fonts and picked up the following fonts for you. These fonts are pretty popular and easy to get. And most importantly, all these fonts are FREE!
  • New open-source web apps available for students and faculty
    Jupyter is an open source web environment for writing code and visualizing data. Over the past few years, it has become increasingly popular across a wide range of academic disciplines. [...] JupyterHub is a variation of the Jupyter project, which adds support for user account management and enterprise authentication. The TLT instance allows students and faculty to log in with their credentials for full access to their own Jupyter environment and provides direct access to their Penn State Access Account Storage Space (PASS). Using PASS for storage provided a large persistent storage space that students and faculty were already familiar with and was easily accessible from the local lab systems or their personal devices.
  • An Ultrasound Driver With Open Source FPGAs
    Ultrasound imaging has been around for decades, but Open Source ultrasound has not. While there are a ton of projects out there attempting to create open ultrasound devices, most of this is concentrated on the image-processing side of things, and not the exceptionally difficult problem of pinging a sensor at millions of times a second, listening for the echo, and running that through a very high speed ADC. For his entry into the Hackaday Prize, [kelu124] is doing just that. He’s building an ultrasound board that’s built around Open Hardware, a fancy Open Source FPGA, and a lot of very difficult signal processing. It also uses some Rick and Morty references, so you know this is going to be popular with the Internet peanut gallery. The design of the ultrasound system is based around an iCE40 FPGA, the only FPGA with an Open Source toolchain. Along with this, there are a ton of ADCs, a DAC, pulsers, and a high voltage section to drive the off-the-shelf ultrasound head. If you’re wondering how this ultrasound board interfaces with the outside world, there’s a header for a Raspberry Pi on there, too, so this project has the requisite amount of blog cred.
