    A container is

    • a lie you tell to a new process (actually not, this is just a namespace)
    • a boundary for your application (actually not, this is just a cgroup)

    and none of the above. There is a lot of confusion in this article, reading it leads to “containers are better for security” but that’s not what I discovered about containers, they lead to better isolation.

    I liked more this attempt but it’s true that containers definitions are pliable, everyone has one, with features attached.

      Don’t be fooled by whoever flagged this as spam – I honestly have no clue why they could have. It’s technical, specific, has an interesting angle, and contains no links to any company.

        It wasn’t me, but most likely it was flagged as spam because it is hosted on medium.

        FTR I consider any post on medium to be spam but I won’t flag them as such because the community thinks otherwise

          I see, thank you for sharing that. May I ask what the word ‘spam’ means to you, and why you experience Medium posts as spam? I feel like the word is taking on a new meaning next to the older ‘unsolicited (self-)advertisement’ and ‘meaningless/uninteresting content’ senses, but I don’t know this new meaning yet, and I’d like to get an idea.

            I wouldn’t necessarily categorize (let alone flag) medium posts as spam, though I fully agree with PuercoPop’s point w.r.t. unsolicited ads. But I have to say the dick bars annoy me more than ever before and in fact I just thought about blacklisting the whole domain in my hosts file as I was trying to read an interesting article (linked from HN) and couldn’t bear the UX. Now reader mode isn’t far away but I’m really irritated that I have to work around such terrible design in the first place. And I’m irritated that it’s been like that for a long time, people have complained about it for a long time, and medium is clearly not interested in fixing it. Fuck them..

              The meaning unsolicited advertisement works perfectly for me. Every time I open a medium post I see a huge banner from medium. Granted the people how publish in medium are more like unknowing accomplices to the spam, but it is still spam.

              I think more than taking a new meaning, some people have normalized spam because of its perverseness in the web.

              1. 1

                I understand now. Thank you.

          This helps reinforce the ‘shortcut’ I’ve been using to help explain containers to more unix-aware folks who are otherwise having trouble with the concept - “containers are a glorified/tarted-up chroot”. I’ll start sharing this article along with my pity witticism to help further clarify the concept. Many thanks for sharing!

            I used to call them tarballs with sockets, I still think it fits.

            Short, but interesting.
