  • I started using Linux every day in 1999 and I’m glad I did.

    Managing a Linux server is no different from managing a Linux desktop. If you were to consider the GUI nothing more than a display layer over the top of a server, you’d have a good mental map of how things work.

    To get started, use the same desktop distro as your server and use their preferred or default windowing system.

    Once you’ve familiar with it and the pitfalls it comes with, you’ll know which questions to ask for your next choice, but you will be able to build on what you already know.


  • I’m not a concrete expert, but a tonne of concrete is less than half a cubic metre.

    A concrete truck carries 10 cubic yards, or nearly 18 metric tons of concrete.

    If this “educational fact” is true, then that amount of sugar might cause an issue with a piece of sidewalk, but it’s unlikely to get noticed on anything being built with concrete, unless you bring a metric shit ton of sugar to the party.

    As it happens, sugar appears to be added to concrete on purpose, specifically to increase the working time at the potential cost of weakening the structure, but research into that is ongoing.

    In other words, this post is bollocks.

    Edit: After it was pointed out to me by @Lupus@feddit.org that my link was slop, which I agree after reading more than the first two paragraphs, I went looking for better information and found this actual research:

    https://www.sciencedirect.com/science/article/pii/S221450952030036X

    Interestingly during my search for information in relation to sugar added to concrete, my results appeared overwhelmingly generated by LLM, like the top link I found initially.

    Also, adding sugar appears to increase the compressive strength and that might be more significant than the increased work time.


  • It appears to be an attempt to monetize open source software, something which should in my opinion be applauded, given the trillions of dollars made off the backs of software developers who contributed to OSS without ever getting compensation, something that’s required to have a roof over your head and food to eat.

    Another approach being attempted in this space is by Bruce Perens (of Open Source fame).

    He’s calling his efforts Post Open: https://postopen.org/
