Edge AI camera runs Linux on quad -A53 SoC with Google Edge TPU

Filed under

Imago’s 5MP “VisionAI” camera runs Linux on a quad -A53 SoC accompanied by a Google Edge TPU for TensorFlow Lite and AutoML Vision Edge. Other features include 2GB DDR4, microSD, GbE, and DIO.

Imago Technologies GmbH announced a “freely programmable,” 5-megapixel edge AI camera designed for AI/ML and deep learning enabled image processing applications including pattern recognition, classification, anomaly or defect detection, and code reading. The VisionAI embedded camera runs Debian Linux on an unnamed quad-core, Cortex-A53 SoC clocked to 1.8GHz. Our guess is the i.MX8M Mini, but the same profile applies to a few other SoCs such as the Actions S900.

The SoC is paired with Google’s Coral Edge TPU AI accelerator. It is unclear if Imago is deploying the Edge TPU via the solderable, LGA form-factor Coral Accelerator Module or one of the M.2 or mini-PCIe modules. The Edge TPU offers 4-TOPS AI processing power using 0.5 watts for each TOPS (2 TOPS per watt).

Linux 101: What are the Linux systemd equivalents of runlevels?

Filed under

If you're a Linux admin, you probably remember the old runlevels, which defined a state of initialization the operating system is running in. For example, runlevel 0 was a system halt, runlevel 1 was single-user mode, runlevel 2 was multi-user mode with no network file system, run level 3 was multi-user mode with a text-only interface, run level 4 was user-definable, runlevel 5 was multi-user mode with a GUI and runlevel 6 was reboot.

That was with sysvinit. Now that most Linux distributions have migrated to systemd, you might be curious as to the equivalent run levels. There isn't a per-level equivalent, because opts to go with target levels, instead of run levels. Because there are only five targets, it doesn't quite map out perfectly.

Megapixels 1.0 released, bringing hardware accelerated graphics to the camera app for Linux phones

Filed under

Pine64’s PinePhone has a 5MP rear camera and a 2MP front-facing camera. But when early versions of the phone began shipping, there wasn’t any software that would actually let you snap photos.

So developer Martijn Braam created Megapixels, which wasn’t the first camera app for the PinePhone, but which has certainly become the most fully-functional. It’s also been ported to work with Purism’s Librem 5 smartphone.

Now the camera app is even better. Megapixels 1.0 is now available and, among other things, it adds support for hardware-accelerated graphics, allowing the phone’s viewfinder to provide a nearly real-time preview as you line up your shot.

Linux Mint’s ‘Warpinator’ file transfer app arrives on Android

Filed under

The process of copying files from one computer to another can be surprisingly difficult, especially without using flash drives or other external storage. That’s why the developers behind the Linux Mint desktop operating system developed Warpinator, an application for copying files over a local network. However, the tool only worked on Linux-based systems, until now.

Warpinator was released by the Linux Mint project in September of last year, and it can be installed on many other Linux distributions (including the Linux container on Chrome OS) through the Flatpak version. Czechia-based developer Slowscript has now created an Android application using the same protocol (via OMG Ubuntu). The app can be used for copying files to/from a Linux PC with the original Warpinator app, or copying data from other Android devices. In the latter case, it’s an alternative to Google’s own Nearby Share, which only works on devices with Google Mobile Services.

Here are Collabora’s Contributions to Linux Kernel 5.12

Filed under

Linux kernel 5.12 was just released last week, bringing numerous new features and improved hardware support. Among the biggest changes, there’s LTO support in Clang, a new dynamic thermal power management mechanism, initial support for zoned block devices for the Btrfs file system, kernel thread-based NAPI polling, eMMC inline encryption support, and support for the Lenovo IdeaPad platform profile.

Collabora’s contributions to Linux kernel 5.12 targeted the closing of the gap between hardware support on vendor trees and the mainline kernel tree. For that, they’ve contributed to the ChromeOS EC platform support, power/supply and reset/shutdown subsystems, Mediatek SoC support, and improved the V4L2 (Video4Linux) Async notifier API to be consistent and easier to use.

11 Best Free Linux Astronomy Apps (Updated 2021)

Filed under

Astronomy is a branch of science that deals with the study of celestial objects (including stars, planets, moons, comets, asteroids, meteor showers, nebulae, star clusters and galaxies) and other phenomena.

We were introduced to the world of astronomy by the venerable Sir Patrick Moore. For anyone who does not know, Sir Patrick was an amateur astronomer who presented The Sky at Night, the longest-running television programme, for over 54 years, and made an outstanding contribution to astronomy.

Astronomy is particularly well suited to the layperson. It’s a wonderful hobby which has almost no age limits, it is open to individuals of all financial means, and there is always the potential for an amateur to discover something that has eluded professional astronomers, or to help monitor stars and track asteroids. Even with the unaided eye, there is much to study in the night sky including constellations, shooting stars, planets, and of course the moon, the Earth’s only natural satellite.

Keep multiple Linux distros on a USB with this open source tool

Filed under

Giving friends and neighbors a bootable USB drive containing your favorite Linux distribution is a great way to introduce neophyte Linux users to the experience we all enjoy. There are still a large number of folks who have never heard of Linux, and putting your favorite distribution on a bootable USB drive is a great way to break the ice.

A few years ago, I was teaching an introductory computer class to a group of middle schoolers. We used old laptops, and I introduced the students to Fedora, Ubuntu, and Pop!_OS. When the class was over, I gave each student a copy of their favorite distribution to take home and install on a computer of their choice. They were eager to try their new skills at home.

Taiwins 0.3 is out

Filed under

Hi all,

I am glad to announce that Taiwins 0.3 is released today. It has been
a year since Taiwins 0.1 release, we have migrated from libweston and
wlroots. This version, Taiwins has implemented enough compositor
features. The biggest change in the version is the libtaiwins library
is finally ready for daily use.

- Multiple backends for hardware abstraction(DRM, X11, wayland).
- Rendering context with exposed interface for custom rendering.
- Abstracting xdg-surface , wl_shell_surface and xwayland_surface for
unified desktop interface.
- session handling.
- All essential and many useful wayland protocols.
- Xwayland support.

With those features supported, libtaiwins now becomes a real
alternative outsides wlroots and libweston. Besides, I’d like to point
out some design goals were kept in mind when crafting taiwins since
day 1.

- split GBM buffer management from DRM mode setting, make it possible
to implement other buffer management backends.

- builtin support for multi-GPUs from day one.
- udev events monitoring for runtime GPU events handling.
- separate rendering logic from backends, make it possible to work
with different renderers.

It is a magical thing to be able to use your own created compositor,
it is certainly not easy, but I think right now the most difficult
time is behind us. The next version of taiwins will focus on the
rendering. Features hopefully will land includes:

- xdg-decoration support
- plane assignment in drm backend
- video recording feature
- taiwins shell functionalities

For people who are interested, hosts many useful
documentations and a tutorial on how to use libtaiwins.

  • How to safely remove PPA repositories in Ubuntu – Linux Hint

    Ubuntu is the most common Linux system that assists users in installing the application by using PPA. PPA is abbreviated as “Personal Package Achieve”. Repositories are servers that have a set of packages. PPA is a collection of packages that are hosted on the Launchpad server. Adding PPA means adding a new repository to our system. We can install the application from that repository. PPA repositories are unofficial repositories that are used to connect third-party software to the Ubuntu operating system.

    Ubuntu searches for the application in a package archive that contains most of the applications required by Ubuntu users. Still, newer versions of the same apps that are not as common are not always available in the official repository. A PPA repository can help with this.

    Our system can have numerous repositories installed. The crowded archive of repositories can make the updating process very slow. Therefore, try to keep the required repositories on your system and delete the unwanted or damaged repositories.

  • How to install an FTP server on Ubuntu 20.04 – Linux Hint

    FTP is a protocol that allows us to transfer files between two different servers across a network. It happens between a “server” and a “client” computer. It occurs via ports 20 and 21. Port 21 is used to establish a link between two computers, and port 20 is used to transfer data. At the same time, FTP servers may not be as prominent as they have ever been. They can still be quite helpful, particularly when they are used on the intranet.Companies with an intranet for everyday work have an FTP server that is open to installed files for everyone, and this is simple to do in Ubuntu 20.04.

    This post is covering what the FTP server is and how to install it on Ubuntu 20.04.

  • How to get a hostname/domain name from an IP address in Linux – Linux Hint

    One of the questions that many Linux users ask is how they can retrieve a system’s hostname using its IP address. It may seem an uphill task, but in the real sense, it’s quite easy. Essentially, this is known as the reverse DNS lookup. Reverse DNS lookup queries an IP address to retrieve the hostname or domain of the server. The exact opposite is the Forward DNS lookup which maps the domain name to the IP address.

    In this short guide, we have explored a few ways to performs Reverse DNS lookup and get a domain name from an IP address. For demonstration purposes, I have used Ubuntu 20.04.

  • How to change ban time fail2ban, even ban forever if desired – Linux Hint

    Fail2ban is an open-source intrusion prevention service that bans IP addresses, making too many logins attempt with the wrong password. By default, the ban period is 10 minutes or 600 seconds. It automatically unbans the IP after 10 minutes to avoid locking out any legitimate system that may have been mistakenly entered the wrong password. If you want, you can easily change (increase or decrease) the default ban time.

    In this post, we will describe how to change ban time in fail2ban. We will also describe how to permanently ban an IP address if you ever need to do so.

  • How can I set the timezone for Crontabs? – Linux Hint

    Crontab, a shortened form of Cron table, is both a command and a text file in UNIX/Linux systems used to determine the scheduling of Cron jobs. What is a Cron job? A Cron job, also widely referred to simply as Cron, is a time-based scheduler that executes tasks in Linux systems at specified times. It runs with the help of the crond daemon Cron jobs are extremely helpful in automating Shell scripts and other commands that need to be executed at regular intervals, which would otherwise be tedious when manually done.

    Usually, Cron jobs run using the local time defined in the system. However, you may prefer to run the Cron job in a different timezone without necessarily changing your server’s time and date.

  • How to Exclude Directory Rsync? – Linux Hint

    Rsync (stands for remote sync) is a very powerful command-line utility for local and remote file and directories synchronization. It comes preinstalled on most Linux distributions. It is one of the best utilities for backup and keeping files and directories on multiple locations in sync. The best part about rsync is that it minimizes the amount of data that is copied to the remote location by only copying the data that has been changed. There is another great feature of rsync that we are going to discuss today; it is excluding files or directories from sync. This is extremely useful during backups when you don’t want to copy one or more files or directories.

    We will show you how you can exclude a file or directory in rsync using different examples. The examples presented here have been tested on Ubuntu 20.04 LTS, however, these are also valid for other Linux distributions having rsync installed.

  • The quest for faster Python: Pyston returns to open source, Facebook releases Cinder, or should devs just use PyPy?

    Facebook has released Cinder, used internally in Instagram to improve Python performance, while another faster Python, called Pyston, has released version 2.2 and made the project open source (again). Python is the world's second most popular programming language (after JavaScript) according to some surveys; but it is by no means the fastest. A glance at benchmarks tells us that Python 3 computation is often many times slower than compiled languages like C and Go, or JIT (Just-in-Time) compiled languages like Java and JavaScript. One reason is that the official implementation of Python, called CPython, is an interpreted, dynamic language, and its creator Guido Van Rossum has resisted optimising it for performance, saying in 2014 that "Python is about having the simplest, dumbest compiler imaginable, and the official runtime semantics actively discourage cleverness in the compiler like parallelizing loops or turning recursion into loops."

  • Cost efficient disaster recovery in hybrid cloud environments

    As more and more organizations move from on-premise datacenters to private, public, and hybrid clouds, it is important to understand that high availability is not the same as disaster recovery (DR). DR planning is needed to recover systems when natural or human-induced disasters hit the primary datacenter/region. Recent public cloud outages suggest that we must have a DR plan in place, even with the high availability provided by the public cloud providers. DR planning should be part of the initial application design discussions, allowing the deployment architecture to accommodate for unforeseen events.

  • Cockpit Project: Testing all the pixels

    The Cockpit integration tests can now contain “pixel tests”. Such a test will take a screenshot with the browser and compare it with a reference. The idea is that we can catch visual regressions much easier this way than if we would hunt for them in a purely manual fashion. Preparing a repository for pixel tests A pixel test will take a screenshot of part of the Cockpit UI and compare it with a reference. Thus, these reference images are important and play the biggest role. A large part of dealing with pixel tests will consequently consist of maintaining the reference images. At the same time, we don’t want to clog up our main source repository with them. While the number and size of the reference images at any one point in time should not pose a problem, we will over time accumulate a history of them that we are afraid would dominate the source repository. Thus, the reference images are not stored in the source repository. Instead, we store them in an external repository that is linked into the source repository as a submodule. That external repository doesn’t keep any history and can be aggressively pruned. Developers are mostly isolated from this via the new test/common/pixel-tests tool. But if you are familiar with git submodules, there should be no suprises for you here.

The first quarter of 2021 has been very active in both FreeBSD-CURRENT and -STABLE, with 13.0-RELEASE work starting in January and finishing up mid-April. It provides lots of new features, and there’s even a good chance that some workloads will experience performance improvements. The number of entries is slightly down, and this is probably due to a combination of factors like code slush as well as the ongoing issues with COVID-19, but we naturally hope that things will look up next quarter. This combined with a switch-over to AsciiDoctor and a decision to make full use of the status report work schedule to avoid stress, means that the report can now be expected to come out at the end of the first month after the quarter has finished, rather than in the middle. This report in particular includes a number of interesting entries, covering everything from the linuxulator, various mitigation work, long-awaited work on OpenBSM, work on kernel sanitizers, and many more things that it is hoped you will enjoy reading about. Yours, Daniel Ebdrup Jensen, with a status hat on. Read more Also: FreeBSD Is Off To A Good 2021 Start With FreeBSD 13.0, PIE By Default, helloSystem
