  • Cyber Security Today – An email gift card scam, please stop re-using passwords and more open data found on Amazon storage

    Welcome to Cyber Security Today. It’s Friday December 6th. I’m Howard Solomon, contributing reporter on cyber security for ITWorldCanada.com.

  • NetworkManager Adds Support For Enhanced Open / Opportunistic Wireless Encryption

    Opportunistic Wireless Encryption (OWE) provides a means of encrypting wireless data transfers without having any secret/key. Opportunistic Wireless Encryption is advertised as Wi-Fi Certified Enhanced Open. This OWE / "Enhanced Open" standard is now supported by NetworkManager for allowing supported devices connecting to Linux systems to make use of this means of opportunistic encryption. The Wi-Fi CERTIFIED Enhanced Open has been around just since summer of 2018 to better secure open WiFi networks. More details on the standard can be found via Wi-Fi.org.

  • Security updates for Friday

    Security updates have been issued by Debian (libav), Fedora (kernel, libuv, and nodejs), Oracle (firefox), Red Hat (firefox and java-1.7.1-ibm), SUSE (clamav, cloud-init, dnsmasq, dpdk, ffmpeg, munge, opencv, and permissions), and Ubuntu (librabbitmq).

Programming: Vagrant, CSV to JSON and Python Bits

  • A beginner's guide to using Vagrant

    Vagrant describes itself as "a tool for building and managing virtual machine environments in a single workflow. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity, and makes the 'works on my machine' excuse a relic of the past."

  • New Project, Who Dis? - Building SaaS #38

    In this episode, we started a brand new project! I had some internet troubles so this “stream” is actually a local recording from my computer. We created a new Django project from scratch and set up Heroku to handle deployments. In spite of the streaming trouble, we were able to get a bunch done. We started the project from scratch so we made a repository on GitHub with some .gitignore settings tailored for Python projects.

  • RunSnakeRun for Python3 Out

    So I finally pushed out the Python3/wxPython Pheonix compatible release of RunSnakeRun. The Python3 version has to run Python2 in order to load Python2 pstats dumps, and Meliae doesn't AFAIK support Python3 yet, so I expect I'll just drop support for it eventually. The code is now living on GitHub rather than Launchpad.

  • Angular 9 CRUD Tutorial: Consume a Python/Django CRUD REST API

    This tutorial is designed for developers that want to use Angular 9 to build front-end apps for their back-end REST APIs. You can either use Python & Django as the backend or use JSON-Server to mock the API if you don't want to deal with Python. We'll be showing both ways in this tutorial.

  • Django: Angular 9/8 Tutorial By Example: REST CRUD APIs & HTTP GET Requests with HttpClient

    In this Angular 9 tutorial, we'll learn to build an Angular 9 CRUD example application going through all the required steps from creating/simulating a REST API, scaffolding a new project, setting up the essential APIs, and finally building and deploying your final application to the cloud.

Red Hat: Containers and Kubernetes, Systemd Everywhere, AMQ Streams on OpenShift and System Administrators

  • Containers and Kubernetes can be essential to a hybrid cloud computing strategy

    Hybrid cloud is gaining ground among enterprises that want to expand computing resources with public cloud infrastructure while still using their on-premise, data center environments. Adding public cloud can mean more elasticity, scalability, and even faster time to market. But if you want to improve the chances that your hybrid cloud can deliver on its promise, you need to think about adding containers to the mix. Linux containers provide a way to encapsulate application code in a way that makes the code more portable and faster to deploy. More and more organizations are using containers as part of the infrastructure for microservices-based, cloud-native applications. Containers can be portable across environments such as Red Hat OpenShift Container Platform and consistent, so they can speed application delivery times and make it easier for teams to collaborate, even if those teams are working in different deployment environments. And they can serve as a bridge between your data center and public cloud environments.

  • Systemd-homed Looks Like It Will Merged Soon For systemd 245

    Announced back in September at the All Systems Go event in Berlin was systemd-homed as a new effort to improve home directory handling. Systemd-homed wants to make it easier to migrate home directories, ensure all user data is self-contained, unify user-password and encryption handling, and provide other modern takes on home/user directory functionality. That code is expected to soon land in systemd. Systemd-homed was talked about by Lennart as being ready for versions 244 or 245. Now that systemd 244 shipped at the end of November, systemd-homed is looking like it will soon land in Git.

  • Understanding Red Hat AMQ Streams components for OpenShift and Kubernetes: Part 3

    In the previous articles in this series, we first covered the basics of Red Hat AMQ Streams on OpenShift and then showed how to set up Kafka Connect, a Kafka Bridge, and Kafka Mirror Maker.

  • What personality trait most defines a sysadmin?

    When you think of a system administrator, who do you think of? Chances are, most of us have taken a Myers-Briggs Type Indicator (MBTI) test at some point in our careers. For me, my results typically come up as INTJ, and I've always thought the traits associated with that type (introversion, intuition, thinking, judging) have aligned with my interest in technology and the kind of work I enjoy. But that doesn't mean that those are the only characteristics that make a good sysadmin. Far from it. A successful team is made up of a diversity of skills, viewpoints, and personal characteristics.

  • How to identify a strong sysadmin job applicant

    When a company looks for new resources with skills in a specific focus area—especially in IT—the challenge is on. Why? Because only a few in the company, if any, have even a vague notion of how to verify the skills they are looking for. The work of a system administrator is a key function, and if it goes wrong, the very existence of the company is at stake (something I’ve been unfortunate to witness when called in on an emergency rescue effort).
