Linux in Devices: Date Bugs, Robot Operating System (ROS), Splashtop, Citrix

  • Y2K quick-fix crick? 1920s come roaring back after mystery blip at UK's vehicle licensing agency

    Caused by a decision to start Unix time on 1 January 1970 at 00:00 UTC and store the counter as a signed 32-bit integer, the problem could see all manner of legacy devices falling over in the early hours of 19 January 2038 with a numeric overflow.

    While modern applications and operating systems have been patched as the date looms, with 64-bit time used in the likes of Linux (on 64-bit architectures), work is ongoing in dealing with systems that will get uppity about compatibility. Embedded hardware (such as medical devices with lifetimes measured in decades) could well present a particularly thorny problem to resolve.

  • The hottest thing in robotics is an open source project you've never heard of

    According to recent LinkedIn data, artificial intelligence (AI) jobs are up 74% while data science jobs are up 37% since 2015. Perhaps less visible, but emerging quickly in importance, are the robots increasingly powered by that data science. Small wonder, then, that the second-hottest job in LinkedIn's analysis is the robotics engineer, experiencing growth of 40% since 2015.

    While the open source projects behind the rise of data science are reasonably well known (e.g., TensorFlow and Keras, among others), most people aren't aware that robotics is also heavily influenced by open source and, in particular, by the Robot Operating System (ROS). Given the importance of ROS to the swelling open source robotics community, it's worth learning a bit more about it.

  • 10ZiG to Demo BCR via Experimental CER Feature in Citrix Workspace App on Linux-Based Thin Client at Citrix Summit

    10ZiG Technology® is conducting live demonstrations of the Citrix Workspace App’s Browser Content Redirection (BCR) using Chromium Embedded Framework (CEF), displaying its performance improvements, on 10ZiG Linux-Based Thin Clients at Citrix Summit booth #502. In the recent release of Citrix Workspace App for Linux Version 1912, Citrix added support to BCR utilizing the experimental CEF-based engine. This enriches the experience on Thin Clients, as it helps to offload network usage, client-side processing, and graphics rendering directly to the endpoint.

Security Leftovers: BlueTooth, Spectre/Meltdown and Huawei Disputes

  • BlueTooth Security Risks

    Security risks involving bluetooth vulnerabilities include techniques known as: bluebugging, bluesnarfing, bluejacking, denial of service and exploits for different holes. When a device is configured in discoverable an attacker may try to apply these techniques. Today mobile security was strongly increased and most attacks fail, yet sometimes security holes are discovered and new exploits emerge. As mobile devices prevent the user from installing unmonitored software freely most of attacks are difficult to carry out. This tutorial describes the most common Bluetooth attacks, the tools used to carry out these attacks and the security measures users can take to prevent them. [...] While bluetooth attacks aren’t widely used (when compared with other types of attacks like phishing or DDOS) almost every person carrying a mobile device is a potential victim, therefore in our countries most people are exposed, also through bluetooth, to sensitive data leak. On the other hand most manufacturers already patched devices to protect them from almost all attacks described above, but they only can issue a fix after the vulnerability was discovered and published (like with any vulnerability). While there is not defensive software the best solution is to keep the device turned off in public spaces, since most attacks require a short range you can use the device safely in private places. I hope you found this tutorial on Bluetooth Security Risks useful. Keep following LinuxHint for more tips and updates on Linux and networking.

  • Arm Has Many Changes On Tap For Linux 5.6 From Spectre/Meltdown Bits To New RNG

    While the Linux 5.5 kernel isn't even released yet, it's ideally coming out on Sunday should there not be a one week delay. But in any event Arm's Will Deacon has already sent in the pull request of the ARM architecture changes for Linux 5.6.

  • The Pentagon pushes back on Huawei ban in bid for ‘balance’

    Huawei may have just found itself an ally in the most unexpected of places. According to a new report out of The Wall Street Journal, both the Defense and Treasury Departments are pushing back on a Commerce Department-led ban on sales from the embattled Chinese hardware giant. That move, in turn, has reportedly led Commerce Department officials to withdraw a proposal set to make it even more difficult for U.S.-based companies to work with Huawei. Defense Secretary Mark Esper struck a fittingly pragmatic tone while speaking with the paper, noting, “We have to be conscious of sustaining those [technology] companies’ supply chains and those innovators. That’s the balance we have to strike.”

Easy Librem 5 App Development: Flashlight

In my first post on easy application development on the Librem 5 I discussed how to turn a simple shell script that takes a screenshot into a full graphical app with only a few extra lines of code. In this post I will follow up with an even simpler application that took about twenty minutes to write with much of that time involved in reading documentation. My Bright Idea The interesting thing about smart phones is how many other devices they have replaced beyond a regular phone. For instance, there used to be a market for small, pocket-sized digital cameras, but now many people just use the cameras on their smart phones. While some people still do keep a pocket flashlight with them, many people just use the light on their smart phone. I realized that a flashlight app would be another great way to showcase just how easy it is to develop applications for the Librem 5. As applications go the requirements are pretty simple: you need a button to turn on the light, a button to turn off the light, and a button to close the app. Read more
