  • This is the job for the OS.

    You can run most Linux systems with stupid amounts of swap and the only thing you’ll notice is that stuff starts slowing down.

    In my experience, only in extremely rare cases are you smarter than the OS, and in 25+ years of using Linux daily I’ve seen it exactly once, where oomkiller killed running mysqld processes, which would have been fine if the developer had used transactions. Suffice to say, they did not.

    I used a 1 minute cron job to reprioritize the process, problem “solved” … for a system that hadn’t been updated for 12 years but was still live while we documented what it was doing and what was required to upgrade it.




















  • So … the reality of this is that these vulnerabilities exist for all microchips, since the purchaser and the user have absolutely no insight into the innards of any of this.

    Microchips are made all over the globe and rarely … if ever … in a country where the political system matches your own, unless you happen to live in the country where the chips you’re using are actually manufactured there and even then you don’t know who is watching what.

    In other words, this is not a new issue, nor is it limited to one country, it affects all of us.

    While we’re at it, software has exactly the same issues.

    Why do you think that ICT professionals keep advocating for open source solutions?
