A more expressive Bash prompt

Tuesday 21st of January 2020 09:20:19 PM
Bash provides some interesting built-in specifiers for the prompt strings PS1. Some of them are static, like ‘a’ for ‘alert’ (Ctrl-G, the bell, beep, or visible flash), or ‘n’ or r’ for newline or carriage return. Some specifiers are set during Bash’s startup, like ‘h’ for the hostname, or ‘u’ for the username; these don’t change during any particular shell session. Some are more dynamic,

Automating Helm deployments with Bash

Tuesday 21st of January 2020 02:45:46 PM
Some of our applications are hosted in a Kubernetes cluster, and we use GitLab Continuous Integration (CI) to automate deployments and Helm 2 to deploy our applications. Helm charts enable the storage of templates of Kubernetes object YAML files with variables that can be programmatically set from command-line arguments passed when the chart is used during deployments. This allows us to store critical secrets in GitLab-protected environment variables or in Hashicorp Vault and use them within the CI deployment job.

GameMode 1.5

  • Feral's GameMode 1.5 Now Supports Changing The CPU Governor Differently For iGPUs

    With Feral's GameMode 1.5 the big change facing users is for those running integrated graphics. In a change led by an Intel open-source graphics driver developer, GameMode now supports setting an alternative CPU frequency scaling governor for integrated graphics use-cases. Up to now GameMode has defaulted to always using the "performance" CPU frequency scaling governor for normally delivering the best performance, but for integrated graphics that in some situations can lead to lower performance. Due to the integrated graphics and CPU cores sharing the same power envelope, ramping up the CPU performance can throw the graphics performance out of balance and at least for some games lead to lower performance. So with GameMode 1.5, the user can now opt for "powersave" or an alternative governor instead when using an iGPU.

  • Feral Interactive's open source 'GameMode' system performance booster has a new release

    Feral Interactive don't just port a lot of games to Linux, they also work on some open source bits here and there. One of their projects is GameMode, which just got a new release. GameMode is a "daemon/lib combo for Linux that allows games to request a set of optimisations be temporarily applied to the host OS and/or a game process". In simple terms, it can help ensure your Linux PC is giving the game all it can to run smoothly. Looks like someone new is handling the project too, with Alex Smith having left Feral Interactive.

Mozilla on Privacy Badger, Rust and Digital ID Systems

  • Firefox Extension Spotlight: Privacy Badger

    People can't be expected to understand all of the technically complex ways their online behavior is tracked by hidden entities. As you casually surf the web, there are countless techniques different third party actors use to secretly track your online movement. So how are we supposed to protect our privacy online if we don't even understand how the game works? To help answer this, the good folks at the Electronic Frontier Foundation (a non-profit devoted to defending digital privacy) built Privacy Badger--a browser extension designed to give you highly advanced tracking protection, while requiring you to do nothing more than install it on Firefox. No configuration, no advanced settings, no fuss. Once you have Privacy Badger installed, it automatically scours every website you visit in its relentless hunt for hidden trackers. And when it finds them, blocks them.

  • What could an “Open” ID system look like?: Recommendations and Guardrails for National Biometric ID Projects

    Digital ID systems are increasingly the battlefield where the fight for privacy, security, competition, and social inclusion is playing out. In our ever more connected world, some form of identity is almost always mediating our interactions online and offline. From the corporate giants that dominate our online lives using services like Apple ID and Facebook and Google’s login systems to government IDs which are increasingly required to vote, get access to welfare benefits, loans, pay taxes, get on transportation or access medical care. Part of the push to adopt digital ID comes from the international development community who argue that this is necessary in order to expand access to legal ID. The UN Sustainable Development Goals (SDGs) call for “providing legal identity for all, including birth registration” by 2030. Possessing legal identity is increasingly a precondition to accessing basic services and entitlements from both state and private services. For the most marginalised communities, using digital ID systems to access essential services and entitlements from both state and private services are often one of their first interactions with digital technologies. Without these commonly recognized forms of official identification, individuals are at risk of exclusion and denial of services. However, the conflation of digital identity as the same as (or an extension of) “legal identity”, especially by the international development community, has led to an often uncritical embrace of digital ID projects. In this white paper, we survey the landscape around government digital ID projects and biometric systems in particular. We recommend several policy prescriptions and guardrails for these systems, drawing heavily from our experiences in India and Kenya, among other countries. In designing, implementing, and operating digital ID systems, governments must make a series of technical and policy choices. It is these choices that largely determine if an ID system will be empowering or exploitative and exclusionary. While several organizations have published principles around digital identity, too often they don’t act as a meaningful constraint on the relentless push to expand digital identity around the world. In this paper, we propose that openness provides a useful framework to guide and critique these choices and to ensure that identity systems put people first. Specifically, we examine and make recommendations around five elements of openness: multiplicity of choices, decentralization, accountability, inclusion, and participation.

Red Hat/IBM: Red Hat Enterprise Linux, OpenShift 4.3 and OpenSCAP

  • Deploying OpenSCAP on Satellite using Ansible

    In many environments today, security is one of the top priorities. New information security vulnerabilities are discovered regularly, and these incidents can have a significant impact on businesses and their customers. Red Hat customers I talk to are frequently looking for tools they can use to help evaluate and secure their environments. One of these tools is OpenSCAP, which is included in Red Hat Enterprise Linux (RHEL), and can perform compliance and vulnerability scanning on RHEL servers. Satellite makes OpenSCAP easier to use by allowing you to deploy the OpenSCAP agent to hosts, manage the OpenSCAP policies centrally, and to view OpenSCAP reports from the Satellite web interface.
