Filed under
Linux

Husarion unveiled an Arduino-ready “Core2” robotics board for web based prototyping, plus a Linux-ready “Core2-ROS” that adds an RPi 3 or Tinker Board.

San Francisco based robotics firm Husarion, which has previously launched an industrial picker robot called the RoboCore, has gone to Crowd Supply to pitch a new Husarion Core2 prototyping platform for the robotics maker community. The $89 Cortex-M4 based Core2 controller board, which includes an ESP32 WiFi adapter, is also available in a version that runs Linux and Robot Operating System called the Core2-ROS. The ROS version replaces the ESP32 with a WiFi-ready Raspberry Pi 3 or Asus Tinker Board SBC.

Six Things to Do to Secure Your Linux System

Security

Tuesday's Petya slam dunk by the bad guys, which may or may not have been a state sponsored swipe at Ukraine, was only one of several wake-up calls during the last couple of months for the folks taking care of IT security.

At least they should have been wake-up calls, but by the carnage left behind it looks as if a lot of folks have been operating their server rooms on autopilot. Not only were there patches at the ready to plug the vulnerabilities Petya used to do whatever it did (other than the fact that it probably wasn't ransomware, what it did hasn't been entirely sorted out yet), but I've heard credible first hand reports from several largish corporations that didn't have available backups.

8 Best Linux Distros For Programming And Developers (2017 Edition)

Filed under
Linux

Linux-based operating systems are often used by developers to get their work done and create something new. Their major concerns while choosing a Linux distro for programming are compatibility, power, stability, and flexibility. Distros like Ubuntu and Debian have managed to establish themselves as the top picks. Some of the other great choices are openSUSE, Arch Linux, etc.

Linux

Libre Computers’ $25 to $35 “Le Potato” is an RPi 3 clone that runs Android 7.1 or Linux 4.13 on a quad -A53 S905X. There’s no WiFi, but you get HDMI 2.0.

A Shenzhen based Libre Computer Project from Shenzhen Libre Technology Co. Ltd. has gone to Kickstarter to launch the first of a series of “Libre Computer Boards” called Le Potato. The project has so far received less than $4K toward its $25K all or nothing goal, with the campaign due to finish on July 24. However, if the project doesn’t fund, “we will utilize our other pre-prepared financing option and go directly to retail,” says the company.

Is Ubuntu set to be the OS for Internet of Things?

Filed under
Ubuntu

The Internet of Things has enjoyed major growth in recent years, as more and more of the world around us gets smarter and more connected.

But keeping all these new devices updated and online requires a reliable and robust software background, allowing for efficient and speedy monitoring and backup when needed.

Software fragmentation has already become a significant issue across the mobile space, and may threaten to do so soon in the IoT.

  • How my students taught me to code

    "Hello, I'm Miss Jess, and my students taught me how to code." When I say this to new students, they often think I misspoke. But it's true. Coding always interested me, but it seemed inaccessible. Then my students taught me to code a video game during a few lunch breaks. Their encouraging advice and suggestions helped me create my first video game using Scratch. The game was simple. It was about a monkey catching bananas as they fell from the sky. If you caught a ripe banana, you earned points.

  • ssh-copy-id: call for testing

    After a prolonged period of neglect, I've finally got round to putting the various patches I had laying around into some sort of order, and pushing them somewhere public, so it would be great if people could test them.

    There are two branches that I'd like people to try:

  • How to rename columns in Pandas Dataframe

    In this tutorial, we will cover various methods to rename columns in pandas dataframe in Python. Renaming or changing the names of columns is one of the most common data wrangling task. If you are not from programming background and worked only in Excel Spreadsheets in the past you might feel it not so easy doing this in Python as you can easily rename columns in MS Excel by just typing in the cell what you want to have. If you are from database background it is similar to ALIAS in SQL. In Python there is a popular data manipulation package called pandas which simplifies doing these kind of data operations.

  • How to use Ansible to update your Django web app

    Now, as you have overcome or evaded the reefs, shoals and swirls of initial development and deployment and your appetite grows, you ask “How do I automate the update and restart of my web app when I change the code?” There is already one simple and elegant method on our blog, that uses one of the possible push to publish methods, but this time we will dip our toes into vast waters of Ansible automation. You may think that using Ansible for a simple task like this is overkill, and it’s a valid thought, but our example is a good practice case that introduces multiple elements that can be used later for much bigger projects. That’s why, instead of writing a simple bash or python script, we will build a full Ansible playbook with accompanying configuration.

  • Using bash’s shopt builtin to manage Linux shell behavior

    If you haven’t tried it yet, you might be surprised by the many features of shopt. While it works like a Linux command, it’s actually a bash shell builtin that allows you to change many things about that shell’s behavior. One option, for example, allows the shell to fix minor typos when you type directory names. To demonstrate, in the first cd command shown below, the directory name, bin, is typed with an extra letter and the shell complains and gives up:

  • Find security issues in Go code using gosec

    It's extremely common now to encounter code written in the Go programming language, especially if you are working with containers, Kubernetes, or a cloud ecosystem. Docker was one of the first projects to adopt Golang, Kubernetes followed, and many new projects select Go over other programming languages. Like any other language, Go has its share of strengths and weaknesses, which include security flaws. These can arise due to issues in the programming language itself coupled with insecure coding practices, such as memory safety issues in C code, for example. Regardless of why they occur, security issues need to be fixed early in development to prevent them from creeping into shipped software. Fortunately, static analysis tools are available to help you tackle these issues in a more repeatable manner. Static analysis tools work by parsing source code written in a programming language and looking for issues.

Feature Requests, Submit Requests for openSUSE Jump Take Shape

The openSUSE Project is progressing with the state of openSUSE Jump, which is the interim name given to the experimental distribution in the Open Build Service. openSUSE Leap Release Manager Lubos Kocman sent an email to the project titled “Update on Jump and Leap 15.3 and proposed roadmap for the next steps” that explains the progress that has been made with Jump 15.2.1. “We have some exciting news to share about the openSUSE Jump effort!” Kocman wrote. “We will have a Jira partner setup (coming) for openSUSE this week!” Access to Jira will allow openSUSE Leap contributors to see updates on community feature requests and be able to comment on requested information or allow them to request information. The process will be tested initially by one of the community members to see if it works properly. Read more
