Ubuntu

As the world is moving toward cloud-based services, we can perform almost every task using a single Web browser. This is one of the reasons why Chrome OS integrated with the Google Chrome web browser has become the most popular web-centric operating system.

Even though Chrome OS uses Linux kernel under the hood, it is exclusively available to run only on Google’s hardware like Chromebook. Hence, if you’re looking for an alternative, soon you’ll be able to experience the potential of cloud computing right on your laptop using Ubuntu Web.

Ubuntu

Adlink claims superior ease of use due to the camera’s compact all-in-one design and its pre-installed AI software. Optimized for machine vision, the stack integrates Ubuntu 18.04 L4T (Linux for Tegra) with Nvidia’s Jetpack 4.3 AI software, Basler Pylon 5.2.0.13457, and machine vision sample code. There is no mention of support for the related, Kubernetes/OpenShift enabled Nvidia EGX AI edge computing stack, which Adlink launched last year on four Jetson-based embedded computers.

Adlink touts the NEON-2000-JT2 for its safety certification from both the FCC and CE (European Commission) The camera is said to be validated for shock (11ms, 30G, half sine, 3 axes), vibration (5-500Hz, 5 Grms, 3 axes), and temperature stability (0 to 45°C). Typical power consumption is 30W. The 123.3 x 77.5 x 66.8mm, 700-gram camera offers EMC and ESD protections and optional IP67 compliance against ingress.

Ubuntu vs. Linux Mint: Which One Should You Use?

Filed under
Ubuntu

Linux Mint, while based on Ubuntu, has a different approach than Ubuntu for creating a Linux distribution. Ubuntu makes use of Gnome 3 and tries to keep everything vanilla, while Linux Mint’s developers take all things they don’t like about Ubuntu and simplify it to make it easier for end users. If you are wondering which one is better, read on to find out how they differ and which one’s best for you.

    Kubuntu 19.10 Eoan Ermine was released on October 17th, 2019 with 9 months support.

    As of July 17th, 2020, 19.10 reaches ‘end of life’.

    No more package updates will be accepted to 19.10, and it will be archived to old-releases.ubuntu.com in the coming weeks.

    The official end of life announcement for Ubuntu as a whole can be found here [1].

    Kubuntu 20.04 Focal Fossa continues to be supported.

  • Ubuntu 19.10 (Eoan Ermine) End of Life reached on July 17 2020

    This is a follow-up to the End of Life warning sent earlier this month to confirm that as of today (July 17, 2020), Ubuntu 19.10 is no longer supported. No more package updates will be accepted to 19.10, and it will be archived to old-releases.ubuntu.com in the coming weeks.

    Ubuntu announced its 19.10 (Eoan Ermine) release almost 9 months ago, on October 17, 2019, and its support period is now nearing its end. Ubuntu 19.10 will reach end of life on Friday, July 17 2020.

  • Canonical partners with global systems integrators

    Canonical, publisher of the Ubuntu Linux distribution, is pursuing the 12 largest global systems integrators as it positions itself as an alternative to VMware and Red Hat.

    The London-based company this week launched a global integrator program, which spans Canonical's open source offerings for data centers, multi-cloud environments, edge computing and IoT. The Canonical partner program provides pricing discounts through deal registration, as well as aggregated volume discounts across partners' combined customer bases. Other features include an updated portal and dedicated account management, sales, engineering and marketing support resources.

    Regis Paquette, vice president of alliances at Canonical, estimates a dozen companies based in the U.S., Europe and India represent two-thirds of the global SI market. Canonical has "selected those 12 as the starting line" for its integrator initiative. "We are really taking a targeted approach," he said.

    Canonical in recent years has focused its partner efforts on building closer relations with hardware vendors such as Dell, Hewlett Packard Enterprise and IBM, while also revamping its value-added-reseller strategy. Integrators, however, began to approach Canonical as their customers sought open source alternatives to VMware, Paquette explained. In addition, two large integrators have tapped Canonical's open source technology to build digital transformation platforms.

Michael Larabel: I've Been Running The AMD Ryzen 7 4700U + Ubuntu 20.04 As My Main System

Filed under
Hardware
Ubuntu

For about one and a half months now I have been using the AMD Ryzen 7 4700U as my main laptop paired with Ubuntu 20.04 LTS. It's been working out very well for not even being the top-of-the-line AMD Renoir SKU. Here is some additional commentary for those thinking about one of the new AMD laptops with Linux use.

Back in May I picked up a Lenovo IdeaPad 5 in order to deliver AMD Ryzen 7 4700U Linux benchmarks. This laptop for just over $800 USD came with a Ryzen 7 4700U, 16GB of RAM, 1080p display, 512GB NVMe storage. The performance of the Ryzen 7 4700U as an 8-core part with 2.0GHz base clock and 4.1GHz boost has been quite good and better than the Intel Whiskeylake Core i7 Dell XPS laptop I had been using as my daily driver. The Renoir graphics are also quite good for desktop use-cases.

[...]

So all in over one month after moving to a Lenovo IdeaPad with Ryzen 7 4700U running Ubuntu 20.04 LTS, I am quite happy with the laptop itself, the performance out of the Ryzen 7 4700U, and Ubuntu 20.04 for that matter as my daily OS these days. This IdeaPad has even been probably the cheapest laptop I've used as my daily system at least in many years if not ever yet the performance with the Ryzen 7 4700U has been great, the build quality of the laptop is good enough when being predominantly in the office attached to a keyboard and 4K display, and the Linux support is there if using a new enough kernel. This is also the first time in more than one decade my main laptop has been AMD powered. As for using Ubuntu again as the OS on my main production system, I am very happy with how Ubuntu 20.04 LTS turned out.

  • Release Team Asks for Feedback on openSUSE Leap "15.2"

    The openSUSE release team is would like feedback from users, developers and stakeholders about the release of the of community-developed openSUSE Leap 15.2 through a survey.

    The survey is available at https://survey.opensuse.org.

    openSUSE Leap 15.2 was released on July 2. Two weeks of people installing the release and using it is a good timeframe to capture fresh ideas and thoughts about how people felt about the release. The survey centers on these two questions: what went well and what didn’t go well?

    That is the question the release team is asking of those who installed and used openSUSE Leap 15.2.

    The team hopes the feedback will provide enough information to help improve the release processes and other elements people found important.

    The survey will close on August 4.

  • DebConf Videoteam Sprint Report -- DebConf20@Home

    DebConf20 starts in about 5 weeks, and as always, the DebConf Videoteam is working hard to make sure it'll be a success. As such, we held a sprint from July 9th to 13th to work on our new infrastructure.

    [...]

    For DebConf20, we strongly encourage presenters to record their talks in advance and send us the resulting video. We understand this is more work, but we think it'll make for a more agreeable conference for everyone. Video conferencing is still pretty wonky and there is nothing worse than a talk ruined by a flaky internet connection or hardware failures.

    As such, if you are giving a talk at DebConf this year, we are asking you to read and follow our guide on how to record your presentation.

    Fear not: we are not getting rid of the Q&A period at the end of talks. Attendees will ask their questions — either on IRC or on a collaborative pad — and the Talkmeister will relay them to the speaker once the pre-recorded video has finished playing.

  • Abhijith PA: Workstation setup

    Recently I’ve seen lot of people sharing about their home office setup. I thought why don’t I do something similar. Not to beat FOMO, but in future when I revisit this blog, it will be lovely to understand that I had some cool stuffs.

    There are people who went deep down in the ocean to lay cables for me to have a remote job and I am thankful to them.

    Being remote my home is my office. On my work table I have a Samsung R439 laptop. I’ve blogged about it earlier. New addition is that it have another 4GB RAM, a total of 6GB and 120GB SSD. I run Debian testing on it. Laptop is placed on a stand. Dell MS116 as external mouse always connected to it. I also use an external keyboard from fingers. The keys are very stiff so I don’t recommend this to anyone. The only reason I took this keyboard that it is in my budget and have a backlit, which I needed most.

  • Best practices for an effective remote team in the world of cloud delivery

    Effective communication between customers, engineers, and project managers is the most critical element of successful cloud delivery. This has always been the case, but it is doubly important in the absence of regular, face-to-face contact.

    For remote teams, instant messaging is an invaluable tool. Internally, we use instant messaging both to keep in touch with one another and to coordinate on projects. However, it’s important to keep these two purposes separate. Maintaining one social channel and one business-focused channel prevents casual conversation from disrupting work.

    For communication with customers, the use of email is the standard tool. Indeed, official design decisions should not be made lightly and need to be documented. In order to avoid delays and have everyone stick to action points, we make sure to chase up through phone or message, but always need to communicate through email. This helps ensure that both parties stay up-to-date on a project’s status and that we have written confirmations.

Optimised authentication methods for Ubuntu Desktop

Still counting on passwords to protect your workstation? When set up properly, alternatives to passwords provide a streamlined user experience while significantly improving security. These alternative authentication methods can also easily be combined to create a custom and adaptive authentication profile. This whitepaper introduces three popular authentication methods that provide a solid alternative to passwords. Perhaps you’d like to configure your laptop for login using a YubiKey hardware token connected to a dock. Another option could be to login with a Duo push notification when not connected to the dock, but use a Google Authenticator one-time password when no network is available. Maybe you need a separate hardware token just for ssh authentication, and you always need to keep a long, complex password for emergency authentication should all other methods fail. All of these scenarios can be easily configured within Ubuntu. Read more

Open Hardware: Arduino, RISC-V and 96Boards

  • Arduino-controlled robot arm is ready to play you in a game of chess

    If you’re tired of playing chess on a screen, then perhaps you could create a robotic opponent like Instructables user Michalsky. The augmented board runs micro-Max source code, enabling chess logic to be executed on an Arduino Mega with room for control functions for a 6DOF robotic arm. The setup uses magnetic pieces, allowing it to pick up human moves via an array of 64 reed switches underneath, along with a couple shift registers. The Mega powers the robot arm accordingly, lifting the appropriate piece and placing it on the correct square.
