How to turn CentOS 8 into a perfect desktop

Filed under
Red Hat

Traditions are there so they can be maintained, nourished, upkept, repeated. Most notably, any time there's a new major CentOS release, I happily jump on the opportunity to test the distro and also provide you with a tutorial that shows all the steps you need to undertake to turn a fairly boring server distro into a fully productive, fun desktop setup.

We've done this with CentOS 6 and CentOS 7 (and there are sequels, too), and it's time we do the same with CentOS 8. So let me show you all the bits and pieces you require to enjoy stability with the latest and greatest software. Over the years, this effort has become easier, so it will be interesting to see whether CentOS 8 makes it even simpler than the previous versions. Let's begin.

  • Technical Leadership Paths

    My favorite projects to work on are high impact and difficult to execute even if there not deeply technical. In fact, I've found that my most impactful projects tend to only have a small technical component. Instead, the real value tends to come from spanning a few different technical areas, tackling some cultural change, or taking time to deeply understand the problem before throwing a solution at it. Framing these projects as "strategic" help me put my thumb on the type of work I like doing.

    Keavy also calls out strike teams as a valuable way for ICs to work on high impact projects without moving into management. In my last three years at Mozilla, I've been fortunate to be a part of several strike teams and upon reflection I find that these are the projects I'm most proud of.

  • People of WordPress: Kim Parsell

    In order to understand how highly valued the WordPress community was to Kim Parsell, you have to know a bit about her environment.

    Kim was a middle-aged woman who lived off a dirt road, on top of a hill, in Southern rural Ohio. She was often by herself, taking care of the property with only a few neighbors up and down the road.

    She received internet access from towers that broadcast wireless signals, similar to cell phones but at lower speeds.

  • How Open Source Software Is Defining the Future of Mobile Connectivity

    Mobile operators face intense pressure to deliver more data, faster connectivity, better coverage and more functionality to end users who are (unfortunately) more demanding than ever. Increasingly, these end users will not be people as we know them but rather Internet of Things (IoT) devices. IDC has projected that by 2025, 60% of the world’s data will be generated by enterprises, double its level in 2017, largely due to the growth in connected devices, sensors, automation and related equipment.

  • LG open-sources Auptimizer, a tool for optimizing AI models

    Despite the proliferation of open source tools like Databricks’ AutoML Toolkit, Salesforce’s TransfogrifAI, and IBM’s Watson Studio AutoAI, tuning machine learning algorithms at scale remains a challenge. Finding the right hyperparameters — variables in the algorithms that help control the overall model’s performance — often involves time-consuming ancillary tasks like job-scheduling and tracking parameters and their effects. That’s why scientists at LG’s Advanced AI division developed Auptimizer, an open source hyperparameter optimization framework intended to help with AI model tweaking and bookkeeping.

  • Google Open Sources its Cardboard VR Platform

    More than 15 million Cardboard were sold worldwide, says Google, with over 160 million Cardboard-enabled app downloads. According to Google, the Cardboard contributed to the success of the YouTube Virtual Reality channel and made possible the creation of the education-focused Expeditions app. Google also released precise schematics and assembly instructions that enabled the creation of a number of variations of the original design which were available for as little as $5. Now, Google is trying to replicate this schema by open-sourcing the whole platform to inject new life in it.

  • The real number of open source developers [Ed: Mac Asay or Microsoft is a liar. There's history to this lie from him (calling Microsoft "biggest Open Source company", based on GitHub alone (it's Microsoft's own site!). Perpetuates still... this lie that only what Microsoft controls counts as FOSS. That's like judging the world's dietary preferences/nutrition by India alone because there are "many people there..."]

    I’m not suggesting some nefarious intent to deceive. GitHub folks aren’t like that. But by conflating accounts with developers, GitHub isn’t helping us get any closer to accurate data on the developer population. More importantly, we don’t need to artificially inflate developer numbers in order to establish their importance.

  • [Old] Ransomware and data breaches linked to uptick in fatal heart attacks

    After data breaches, as many as 36 additional deaths per 10,000 heart attacks occurred annually at the hundreds of hospitals examined in the new study. Heart attacks rank among the most common medical emergencies in the U.S., with approximately 735,000 Americans experiencing one every year.

    The number of health care entities affected by electronic breaches has risen 20 percent in 2019 compared to all of last year. Those breaches involved the medical records of 38 million health care customers, the largest number since 2015 when massive hacks struck Anthem, Blue Cross, Excellus and UCLA Health System.

    Electronic medical records, though billed as a modern pathway to efficiency, are already known to cause friction among health professionals, occasionally slowing care and leading to inferior health outcomes. Johnson and his colleagues suspect that the newly installed efforts to thwart future digital breaches are unintentionally amplifying this discord.

  • [Old] Data breach remediation efforts and their implications for hospital quality [iophk: Microsoft Windows kills]

    Principal Findings

    Hospital time‐to‐electrocardiogram increased as much as 2.7 minutes and 30‐day acute myocardial infarction mortality increased as much as 0.36 percentage points during the 3‐year window following a breach.


    Breach remediation efforts were associated with deterioration in timeliness of care and patient outcomes. Thus, breached hospitals and HHS oversight should carefully evaluate remedial security initiatives to achieve better data security without negatively affecting patient outcomes.

  • Study: Ransomware, Data Breaches at Hospitals tied to Uptick in Fatal Heart Attacks

    Hospitals that have been hit by a data breach or ransomware attack can expect to see an increase in the death rate among heart patients in the following months or years because of cybersecurity remediation efforts, a new study posits. Health industry experts say the findings should prompt a larger review of how security — or the lack thereof — may be impacting patient outcomes.

  • Linux Dying In Dependency Hell

    There is a concept in computer programming of “Dependency Hell”. It comes about, IMHO, when folks forget to follow the K.I.S.S. principle (Keep It Simple, Stupid.) and / or just don’t pay attention to a couple of basics of computing. In particular, to realize that ALL change is incredibly expensive in time and effort while changes that are incompatible with other parts of the system (or other changes) can be lethal (to the project, product, or whole system).

    The Unix Way of “Do one small thing and do it well” comes from this understanding. One Small Thing done well is unlikely to change much. If I have a program that just takes a byte stream and directs it to a file, that’s not got a lot of room for “enhancements”, revisions, or bugs. If my “Init Systems” just launches a PID1 (Process ID #1) that launches some other processes listed in a script or configuration file, well, my init system is unlikely to ever need much change, revision, “enhancement”, nor will it have much in the way of bugs (if any). This has been fundamental and true for about 50 years of Unix history.

    What has happened relatively recently is an explosion of (gratuitous?) change and “enhancement” that looks to me like it is NOT making things better and IS making things worse. Simply because it makes for a huge growth in Dependency Hell issues.

  • EU migrations are now live!

    Although our US-based systems are fully GDPR-compliant, thanks to the EU-US Privacy Shield Framework, we appreciate that some people are keen on keeping all of their data inside the EU so as to be sure that they comply with all regulations.

    If you're based in the EU, there's almost no downside to using the new system. You will have the comfort of knowing your data is in the EU, and it's closer to you in network terms (in our tests, the network latency is about 8ms from Amsterdam, versus 90ms to our US servers). For paid accounts, billing is in euros so you don't need to worry about foreign exchange fees on your card payments. If we need to perform system maintenance on the servers, we'll do it late at night European time, rather than during the early morning timeslot that we use for the US-based system. The only reason you might want to stick with the US system is that it's a little cheaper; our underlying hosting costs are a bit higher for the EU service, which is reflected in the prices -- a Hacker account that costs US$5/month on the US servers is €5/month on our new system (plus VAT if applicable).

  • Why Everyone Working in DevOps Should Read The Toyota Way

    In a former life I was a history student. I wasn’t very good at it, and one of my weaknesses was an unwillingness to cut out the second-hand nonsense and read the primary texts. I would read up on every historian’s views on (say) the events leading up to the first world war, thinking that would give me a short-cut to the truth.

    The reality was that just reading the recorded deliberations of senior figures at the time would give me a view at the truth, and a way to evaluate all the other opinions I felt bombarded by.

    What I should have learned, in other words, was: ignore the noise, and go to the signal.

  • My System Administration Ethics book has been published

    Dear readers, I am truly happy to announce the publication of my latest technical book. It comes with a lengthy but important title - System Administration Ethics: Ten Commandments for Security and Compliance in a Modern Cyber World. A colleague and I have been writing this book over the past year and a bit, and we've jotted down what we believe are the most critical dos and don'ts of information technology.

    Ethics has never been more important - just look around, and you'll see the Wild Wild West of the digital world, breach here, breach there, data this, data that. Amidst this chaos, you will find techies, afloat, lost, confused, angry, and wondering how their work and passion has become the spearpoint of social dissent and mistrust. I hope this book can provide the right pointers.

KaOS Linux Brings Order to the Desktop

KaOS' integration of the K Desktop extracts power and productivity while reducing distractions. Two things make KaOS an outstanding Linux distro choice: Beginners find it relatively easy to use; and advanced users can customize the environment to their hearts' content.

KaOS targets users who want a Linux distro that puts all of its resources toward working in one environment. You would think that all Linux distros should have that goal, right?

Distros with multiple desktops often suffer from fragmented goals with numerous side concerns. Most of the distros with single or even two desktop options fail to reach the same degree of application selection and performance-tweaking that you find in KaOS Linux.

Debian reconsiders init-system diversity

The immediate motivation for a reconsideration would appear to be the proposed addition of elogind, a standalone fork of the systemd-logind daemon, to Debian. Elogind would provide support for systemd's D-Bus-based login mechanism — needed to support small projects like the GNOME desktop — without the need for systemd itself. The addition of elogind has been controversial; it is a difficult package to integrate for a number of reasons. Much of the discussion has evidently been carried out away from the mailing lists, but some context on the problem can be found in this bug report. In short: merging elogind appears to be complex enough that it would be hard to justify in the absence of a strong commitment to the support of non-systemd init systems. It seems possible that this commitment no longer exists across the distribution as a whole; the purpose of a general resolution would be to determine whether that is the case or not. Read more
