    (This is as much an answer to some of the comments already raised, as to the article - which like most such personal pieces has pros and cons.)

    As part of a previous job I used to host email for a small business - this was about 15 years ago. I ended up spending several hours to a day a week working on it; apologising to users, tracing and diagnosing missing sent email and the endless, ENDLESS arms war against incoming spam (phishing was much less of a problem then). The trust from the company in our email operation was very poor and you’d regularly hear someone apologising to a customer because we hadn’t contacted them, or answered their email. The truth is much was going astray and staff were relying more on the phone than email because they knew it worked. You might guess from this that I’m terrible at running an email system but I don’t think I am. I started moving email back in the late 80s when Fidonet was the thing, so I have some miles travelled. Tools have improved a bit since then, but so have those used by the bad guys.

    I still consider one of the best things I did for that company was move our company email onto Gmail Business (which was free for us as a charity) Every single one of those problems went away immediately and suddenly I had a lot more time to do more important stuff. I would never self-host email again despite running several personal servers.

    Plenty of people say they self-host just fine, and great for you if that’s so. But the truth is you won’t always know if your outbound mail silently gets dropped and you have a far higher chance of it arriving if it comes from a reputable source. There are a huge number of variables outside of your control. (ISP, your country, your region, your software, even the latency of your MX or DKIM responses factor into your reputation)

    You take the decision on whether any perceieved risks of privacy through using a third party outweighs the deliverability and filtering issues of self hosting, but please don’t say it’s simple or reliable for everyone. If it’s simple for you, you’re either incredibly lucky or just not appreciating the problem.

    You’re spot on, and even smaller ISPs routinely get blocked by larger hosters (anyone who doubts this, please look around for the many stories along the lines of “gmail silently drops my email”)

    Residential IP blocks are scored much higher and given a negative trust from the start - not surprising since that’s where much of the world’s spam comes from through compromised computers, routers etc.

    My employer paid for a course heavily based on it (No cert, but condensed and more useful), and for my time. One tutor and two pupils over a week.

    I found it moderately interesting, and slightly useful. It was the most relevant training available for administrating our (then) CentOS 5/6/7 servers. There were bits that didn’t transfer across to CentOS, mostly the proprietary RHEL software aspects which we largely skipped. There was much that was useful for any linux distro.

    Highlight for me was properly learning awk during it - I still use that every day.






  • As someone who works in an environment with many Windows and Linux VMs, I can pretty accurately state that Windows updates have caused far more critical problems than Linux ones over the past 2 or 3 years. Microsoft’s Patch QC has been AWFUL. (Print Nightmare fixes caused ongoing problems that are still breaking printing. You mentioned the EFI change, there’s also patching completely failing for machines that had too small a recovery partition. Fine if there was none, or it was large, but all updates fail after that if your machine has a partition that Windows itself silently created.) There’s literally dozens of major Windows update failures recently.

    As you say, shit happens. Paying for something doesn’t make that any less.


  • Fedora is a fork of Red Hat, the same way Ubuntu is a fork of debian.

    I think you’ve got your ordering and terms a bit confused, there. There’s no forking as such going on in the EL ecosystem.

    To explain it as simply as I can, as there are quite a few people mixing this up in here.

    Fedora is *upstream *of Red Hat (Or RedHat Enterprise Linux (RHEL) to be exact - Redhat is a company owned by IBM that does a bunch of stuff, not just RHEL).

    Fedora feeds into CentOS Stream (Essentially a staging area for RHEL). This has no relation to CentOS Linux, which is dead.

    RHEL is then built from CS at point releases and sold commercially through licencing.

    There are distros such as Rocky, Alma, Oracle Enterprise Linux and possibly some smaller ones that strive to be near exact clones of RHEL (Rocky claims bug-for-bug compatibility, Alma doesn’t any more as they build in a different way) - these follow RHEL’s point releases, and might be considered a poor and loose definition of forking, but rebuilding is a more accurate term.

    All these distros are under the blanket term of “Enterprise Linux” because it’s shaped around RHEL, even though most are free. Historically this worked well, as people learned Enterprise skills using Fedora and Centos Linux which turned into careers (including for me). Then Redhat went a bit mad and that all changed.

    The only similarity to Debian/Ubuntu is that Ubuntu uses Debian as a base, and builds upon it. Like RHEL, it adds commercially licenced bits to its distro and rebuilds other parts into something unique, and like RHEL, Rocky, Alma and OEL do with Fedora, it feeds back improvements and development into Debian.

    Bad? It’s a couple of decisions made by organisations or politicians who are ignorant of free software alternatives and open standards.

    Certainly better than the US’s tax system, where you have to pay to file your taxes or at the least, have to spend a lot of your time working out complex tax submissions each year.

    In the UK, your income tax is automatically paid by your employer when you earn it. Unless you’re self employed - or doing your own business accounts like OP, you don’t have to submit any tax information, ever.

    I think you have to be exceptionally strong to resist this sort of thing. You can justify sponsorship in a hundred ways - not least to yourself. But in every case, it changes everything. That, of course, is why companies spend money influencing the influencers.

    Buyer beware, as always.
