  • Jetson Nano Robot | Hackaday

    [Stevej52] likes to build things you can’t buy, and this Jetson Nano robot falls well within that category. Reading the project details, you might think [Stevej52] drinks too much coffee. But we think he is just excited to have successfully pulled off the Herculean task of integrating over a dozen hardware and software modules. Very briefly, he is running Ubuntu and ROS on the PC and Nano. It is all tied together with Python code, and is using Modbus over IP to solve a problem getting joystick data to the Nano. We like it when existing, standard protocols can be used because it frees the designer to focus more on the application. Modbus has been around for 40 years, has widespread support in many languages and platforms.

  • Ryzen Embedded module delivers 32GB RAM and quad displays

    Ibase’s “ET977” is a COM Express Basic Type 6 module that runs Ubuntu or Win 10 on a Ryzen Embedded V1000 or R1000 with up to 32GB DDR4 and up to quad display support plus GbE, PCIe x8, and a USB 3.1 Gen2 interface.

    In July 2019, Ibase announced an ET976 COM Express Basic Type 6 module with AMD’s Ryzen Embedded V1000. Now it has returned with a more advanced ET977 Basic Type 6 entry that adds support for the Ryzen Embedded R1000. Other recent Ibase products based on Ryzen Embedded include the 3.5-inch IB918 SBC and a fanless, embedded ASB200-918 computer based on it.

    [...]

    Although the manual lists only Windows 10, the announcement says the module also supports Ubuntu.

  • Arduino Blog » This LED coffee table reacts to whatever’s on top

    The YouTube team “Ty and Gig Builds” recently decided to make their coffee table a little more interesting, adding a chain of 96 addressable LEDs underneath its clear surface. This would have been neat enough by itself, but their project doesn’t just stop there and instead embeds 154 IR emitters and 154 IR receivers, allowing it to react to what’s on top. Beyond that, it’s able to display animations without using the sensors for a mesmerizing effect.

    The setup, as you might imagine, required a lot of wiring along with custom shift register and multiplexer boards to accommodate its vast I/O needs. These discrete I/O are eventually funneled down to an Arduino Mega for control, creating a one-of-a-kind table that should make for a great conversation piece while holding coffee and other knickknacks.

Linux Candy: Hollywood – fill your console with Hollywood melodrama technobabble

Linux Candy is a series of articles covering interesting eye candy software. We only feature open source software in this series. Some of the programs in this series are purely cosmetic, frivolous pieces of fun. Candy at their finest. But we also include some programs that aren’t purely decorative. There’s a diverse range of programs included in this series. Programs such as eDEX-UI and Variety are actually highly practical programs. ASCIIQuarium has soothing and relaxing qualities for your desktop. Other programs included in this series (such as lolcat, cacafire) are included purely for their decorative qualities. And then there’s some really fun software that just raises a smile or two. Hollywood is a 102 line script that occupies your console with tech geekery. Read more

IBM/Red Hat/Fedora Leftovers

  • Open Source Defies Conflicts of Interest: Red Hat Tells All

    Only two parts of the guidelines state any sort of limit on company associates, she clarified. The first is that projects use an Open Source Initiative-approved license. The second is that if an associate is asked to sign a third-party contributor agreement, they should check with Red Hat’s legal team.

  • ANZ moves internet banking to Red Hat OpenShift

    The Australia and New Zealand Banking Corporation (ANZ) in October last year turned to Red Hat for help to bring its internet banking proof of concept to life. The bank wanted to modernise its internet banking platform that had passed its end of life and required extended support for some years. Deciding on a Red Hat OpenShift platform, tech area lead for ANZ's digital arm Raghavendra Bhat said the bank wanted to not constrain itself to a cloud-only solution. ANZ has now migrated 30% of its traffic to the platform and within the first hour of go-live, it processed around AU$2.9 billion worth of payments. Speaking with media on Wednesday, Bhat said the bank's expectation is to complete about 80% of the traffic transition onto the new platform by November, with complete transition by March. He said there has been no "cookie-cutter approach" for how it has lifted and shifted the old system onto the new one.

  • Juggling Ansible, OpenShift and K8s? This is for you: Red Hat couples automation to cluster management

    Red Hat is integrating its Ansible automation platform and Advanced Cluster Management for Kubernetes. “We've known people use Ansible and OpenShift and Kubernetes together for years,” Red Hat senior manager Richard Henshall told The Register. “But here we get a bona fide integration between the two.” Typical uses would be to automate deploying system updates, configuring load balancers, or scaling server resources. The integration is in technical preview. “We’ve got the initial plumbing working, so it’s exposed through Advanced Cluster Management (ACM),” said Henshall, referring to the company’s tool for controlling OpenShift clusters and applications.

  • Why it's important to keep the cloud open | Opensource.com

    There's a famous sticker featured on many laptop lids; it goes something like this: "the 'cloud' is just somebody else's computer." There's a lot of truth to that sentiment, but it's not exactly technically accurate. In fact, cloud computing isn't just somebody else's computer; it's somebody else's hundreds and thousands of computers. Years ago, "the cloud" did indeed just refer to the simplified graphic in a flowchart, so the illustrator didn't have to try to accurately depict the multiple networks that comprise the World Wide Web. Now, however, the cloud isn't just describing traffic or small-time remote file storage offers. The cloud of today is a platform of interconnected computational nodes working together to keep containerized Linux images, each running a distinct service (or "microservice" in developer lingo), functioning as applications distributed over the whole world.

  • Full Disk Encryption, without LVM, by default - Call for comments

    Historically Desktop / Server, only configured LUKS full disk encryption with an LVM layer. Thus ones root ext4 filesystem was an LVM volume, on an VG group, on LUKS, on a GPT partition. The upcoming Ubuntu Core 20 has full disk encryption with TPM support. In that configuration ext4 filesystem is created directly on the LUKS volume which is directly on a GPT partitition. For the upcoming HH 21.04 release, I want to change Desktop/Server, to also install in a similar fashion. Specifically such that by default, we simply use ext4+LUKS without LVM. It seems to me that despite having LVM layer, it’s not actually used or appreciated much. Would you be ok with having full-disk encryption without LVM by default?

  • Ubuntu 21.04 Installer Might Allow EXT4 Encryption Without LVM - Phoronix

    An early proposal by Ubuntu/Canonical developer Dimitri John Ledkov is proposing full disk encryption by default without LVM. With Ubuntu Core 20 there is going to be support for TPM-backed full disk encryption created directly on the LUKS volume and in turn directly on a GPT partition without LVM. For Ubuntu 21.04, the developers are looking at changing the Ubuntu desktop/server installers to potentially allow similar EXT4 encryption directly atop LUKS without LVM.

15 Open-Source Push Notification Projects, Alternative to Apple and Google (Firebase) services

A push notification is the message that pops up on your mobile iOS or Android, and sometimes on your desktop or a web browser. It's often used by application publishers and authors to notify the end-user's device about certain event. It looks like SMS text message and local mobile alerts, but they are application oriented only appears to user who use the application. Users can stop any push notification anytime from their mobile settings in the notifications section. However, they are essential for many applications so the user should be selective when selecting the app. Push technology (server push) are technical term for internet-based communication that occurs when a server notifies the client about certain transaction (notification).
