Gentoo
  • Gentoo Python Guide

    Gentoo provides one of the best frameworks for providing Python support in packages among operating systems. This includes support for running multiple versions of Python (while most other distributions avoid going beyond simultaneous support for Python 2 and one version of Python 3), alternative implementations of Python, reliable tests, deep QA checks. While we aim to keep things simple, this is not always possible.

    At the same time, the available documentation is limited and not always up-to-date. Both the built-in eclass documentation and Python project wiki page provide bits of documentation but they are mostly in reference form and not very suitable for beginners nor people who do not actively follow the developments within the ecosystem. This results in suboptimal ebuilds, improper dependencies, missing tests.

  • No more PYTHON_TARGETS in single-r1

    Since its inception in 2012, python-single-r1 has been haunting users with two sets of USE flags: PYTHON_TARGETS and PYTHON_SINGLE_TARGET. While this initially seemed a necessary part of the grand design, today I know we could have done better. Today this chymera is disappearing for real, and python-single-r1 are going to use PYTHON_SINGLE_TARGET flags only.

    I would like to take this opportunity to explain why the eclass has been designed this way in the first place, and what has been done to change that.

    Why PYTHON_SINGLE_TARGET?

Pentoo – A Security-Focused Linux Distro Based on Gentoo

Security

Pentoo is an open-source Live CD and Live USB Gentoo Linux-based operating system designed for experts in the field of penetration testing and security assessment. It is available for both 32-bit and 64-bit architectures and is can be run as an overlay on an existing Gentoo installation.

If you’re not familiar with Gentoo Linux, it is an advanced Linux distro that enables users to compile their operating system from the source in other to enjoy advantages such as applications and optimal performance specific to the computer, to mention a couple.

It does not have an installer and users are to translate the software they want before continuing with the installation. In short, one shouldn’t go near it if they don’t have the perseverance for filing through Linux documentation.

Just like with Gentoo, Pentoo has an advanced Python-based package management system with cool features such as “fake” (OpenBSD-style) installs, system profiles, config file management, safe unmerging, and virtual packages, among others.

exGENT 2020 Linux Distro Makes Gentoo Fun to Use with the LXQt Desktop

Filed under
Linux
Gentoo

Arne Exton’s exGENT GNU/Linux distribution aims to continue the tradition of Gentoo-based live distros with a new release that puts the latest LXQt 0.14.1 desktop environment in the spotlight.

We all know by now that Gentoo is one of the hardest Linux-based operating systems to install due to packages needing to be compiled from sources locally. But the good thing about Gentoo is that it doesn’t uses a one-size fits all approach, which mens that it can be fully optimized for specific hardware.

Newcomers who want to try Gentoo Linux on their personal computer have a hard time due to the lack of Gentoo-based live distributions. Here’s where exGENT Linux comes into play, promising to offer users an up-to-date Gentoo-based live system that can be installed in a few minutes.

Michał Górny: A distribution kernel for Gentoo

Filed under
Linux
Gentoo

The traditional Gentoo way of getting a kernel is to install the sources, and then configure and build one yourself. For those who didn’t want to go through the tedious process of configuring it manually, an alternative route of using genkernel was provided. However, neither of those variants was able to really provide the equivalent of kernels provided by binary distributions.

I have manually configured the kernels for my private systems long time ago. Today, I wouldn’t really have bothered. In fact, I realized that for some time I’m really hesitant to even upgrade them because of the effort needed to update configuration. The worst part is, whenever a new kernel does not boot, I have to ask myself: is it a real bug, or is it my fault for configuring it wrong?

I’m not alone in this. Recently Михаил Коляда has talked to me about providing binary kernels for Gentoo. While I have not strictly implemented what he had in mind, he inspired me to start working on a distribution kernel. The goal was to create a kernel package that users can install to get a working kernel with minimal effort, and that would be upgraded automatically as part of regular @world upgrades.

Reviews

Many people in the technology world have heard, at least in passing, of the Linux distribution Gentoo. Gentoo is one of the most famous distributions to the point of becoming a joke; with it’s complexity and depth, installing Gentoo has been a daunting task for many.

Redcore is one of the latest distributions to attempt to bring the power of Gentoo to the everyday user.

I previously wrote an article in 2017 about Sabayon Linux, another popular Gentoo based system; but Redcore Linux holds its own and pulls its own weight.

Verifying Gentoo election results via Votrify

Filed under
Gentoo

Gentoo elections are conducted using a custom software called votify. During the voting period, the developers place their votes in their respective home directories on one of the Gentoo servers. Afterwards, the election officials collect the votes, count them, compare their results and finally announce them.

The simplified description stated above suggests two weak points. Firstly, we rely on honesty of election officials. If they chose to conspire, they could fake the result. Secondly, we rely on honesty of all Infrastructure members, as they could use root access to manipulate the votes (or the collection process).

To protect against possible fraud, we make the elections transparent (but pseudonymous). This means that all votes cast are public, so everyone can count them and verify the result. Furthermore, developers can verify whether their personal vote has been included. Ideally, all developers would do that and therefore confirm that no votes were manipulated.

Currently, we are pretty much implicitly relying on developers doing that, and assuming that no protest implies successful verification. However, this is not really reliable, and given the unfriendly nature of our scripts I have reasons to doubt that the majority of developers actually verify the election results. In this post, I would like to shortly explain how Gentoo elections work, how they could be manipulated and introduce Votrify — a tool to explicitly verify election results.

Red Hat: The Vision of Fedora Project and Corporate IBM/Red Hat News

  • The Fedora Project's One Sentence Vision

    Fedora Project Leader Matthew Miller recently talked about his vision for the Fedora Project over the next decade and it to become an "operating system factory", among other advancements he hopes to see out of the project in the 2020s. A one-sentence vision for Fedora is now drafted as their vision statement.

  • Let’s keep writing a new vision statement for Fedora

    If you compare it to the first draft, you’ll notice we shortened it to one sentence. We kept the parts we felt were most important: everyone benefiting from free & open source software and the attributes of the communities that make it. The word benefit is important here. It’s not enough that the software is there, waiting to be used. It has to be accessible and usable. This was much longer in our first draft, so shortening it here seems right. We also cut out the sentence about Fedora being a reference for everyone who shares this vision. We still want to be that, but that’s implied by the fact that we have this vision in the first place. Why bother expressing a vision that we wouldn’t want to be an influential part of? And frankly, it’s hard to get the wording right, especially in a way that works across languages and cultures.

  • Enable Git Commit Message Syntax Highlighting in Vim on Fedora

    When setting up new machines, I’m often frustrated by lack of syntax highlighting for git commit messages in vim. On my main workstation, vim uses comforting yellow letters for the first line of my commit message to let me know I’m good on line length, or red background to let me know my first line is too long, and after the first line it automatically inserts a new line break whenever I’ve typed past 72 characters. It’s pretty nice. I can never remember how I get it working in the end, and I spent too long today trying to figure it out yet again. Eventually I realized there was another difference besides the missing syntax highlighting: I couldn’t see the current line or column number, and I couldn’t see the mode indicator either. Now you might be able to guess my mistake: git was not using /usr/bin/vim at all! Because Fedora doesn’t have a default $EDITOR, git defaults to using /usr/bin/vi, which is basically sad trap vim.

  • Executive Q&A: Stephen Leonard, GM of IBM’s Cognitive Systems

    There is no single path that business executives travel. The best managers have significant talent that is then honed to a fine edge by training, experience and a willingness to take up new challenges. Employers contribute hugely to the process, of course, and it is difficult to think of a company that does a better job of recognizing, training and advancing new leaders than IBM. I recently had a chance to interview Stephen Leonard, General Manager of IBM’s Cognitive Systems where he is responsible for the development, sales and marketing of the company’s Power Systems solutions, as well as offerings for cloud computing platforms and data centers. Our discussion covered a wide range of issues and events that have colored Leonard’s 30+ years with IBM.

  • IBM Sterling enables intelligent orchestration of customer transactions across back-end record systems

    A deep understanding of customers’ wants and needs are key to driving supply-chain efficiencies and enhanced customer experiences. An intelligent call center solution equips customer care representatives (CSRs) with deep insights in a natural language-based conversation interface to solve complex customer queries. On a typical day, a CSR opens multiple tabs/applications to address a single query, spending an enormous amount of time on a customer call, thereby impacting the customer experience. This is especially detrimental during peak business hours, when it is important to resolve issues quickly since there is typically a backlog of waiting calls. Wouldn’t it impress the customer if the CSR proactively asked, “Are you calling about the accessories that you bought yesterday?”, along with a warning that the order may be delayed. Informing the customer and providing a discount voucher or a different added benefit results in a much happier customer. The heart of this improved customer experience is the IBM Sterling Supply Chain Business Assistant With Watson™, which infuses conversational AI capabilities into the IBM Sterling Call Center and enables intelligent orchestration of customer transactions across back-end record systems. It also surfaces recommendations and best next steps based to enable quick and easy decision-making for the CSRs. The Sterling Supply Chain Business Assistant With Watson appears as a pop-up over the IBM Sterling Call Center application and can be embedded into any other application. Sample insights are shown below.

  • Scaling Persistent Volume Claims with Red Hat OpenShift Container Storage v4.2

    For choosing a storage solution for dynamic provisioning of persistent volume claims (PVC) in OpenShift Container Platform, the time it takes to bind and prepare a PVC for the use with application pods is a crucial factor. For Red Hat OpenShift Container Storage v4.2 we performed a series of tests investigating how OCP v4.2 behaves from a scalability point of view. We wanted to know how fast application pods are starting when PVCs are from different storage classes provided, and to get get numbers which can be used when making decisions when choosing storage solution for OCP application pods. The test results presented in this document are recommended values for OpenShift Container Storage v4.2 and do not show the real limits for Openshift Container Storage v4.2, which are higher. We will conduct more scalability tests for future OpenShift Container Storage releases. For future OpenShift Container Storage releases we plan to target configurations for cases when more pods are running on the OpenShift Container Platform cluster and are actively requesting PVCs originating from Openshift Container Storage. In this document we describe test processes and results gathered during PVC scale test execution with Openshift Container Storage v4.2 showing why OpenShift Container Storage is the supreme storage solution for use cases where pod density and PVC allocation speed are key, as e.g. in CI/CD environments.

  • What is a safe space?

    When foreign people come along with a different, but no less valid, Code of Conduct, zealots start screaming out for the comfort of their safe space. That is how we get the hysteria that precipitated the Hanau shooting and the lynching of Polish workers in the UK in the name of Brexit. The Third Reich may have been the ultimate example of the search for a safe space: a safe space for the white Aryan race. Nazis really believed they were creating a safe space. Germans allowed the Nazis to rule, in the belief that they were supporting a safe space. The golden rule of a safe space is that it is only safe for some. As George Orwell puts it, All animals are equal, but some animals are more equal than others. Tolerance and safe spaces are mutually exclusive.

  • The right to be rude

    The historian Robert Conquest once wrote: “The behavior of any bureaucratic organization can best be understood by assuming that it is controlled by a secret cabal of its enemies.” Today I learned that the Open Source Initiative has reached that point of bureaucratization. I was kicked off their lists for being too rhetorically forceful in opposing certain recent attempts to subvert OSD clauses 5 and 6. This despite the fact that I had vocal support from multiple list members who thanked me for being willing to speak out. It shouldn’t be news to anyone that there is an effort afoot to change – I would say corrupt – the fundamental premises of the open souce culture. Instead of meritocracy and “show me the code”, we are now urged tpo behave so that no-one will ever feel uncomfortable. The effect – the intended effect, I should say, is to diminish the prestige and autonomy of people who do the work – write the code – in favor of self-appointed tone-policers. In the process, the freedom to speak necessary truths even when the manner in which they are expressed is unpleasant is being gradually strangled. And that is bad for us. Very bad. Both directly – it damages our self-correction process – and in its second-order effects. The habit of institutional tone policing, even when well-intentioned, too easily slides into the active censorship of disfavored views.
