Yes, they release particles in your body and this seem to cause issues for at least some people. But if there is a long time span between getting the implant and chronic health issues appearing I don't think people will be able to pinpoint that titanium implants might be the cause.
What the article writes about scalability also applies to availability. Does the queue need 99.999% or 99.9999% uptime? Or is the Service Level Objective actually 99.99%, 99.9% or even 99.5%?
With 99.99% you can have 4 minutes of downtime a month. If failover to a hot standby takes a minute then that shouldn't be a problem to achieve a 99.99% uptime SLO.
I don't really want to give anything that seems like medical advice in HN comments. I just want to give a bit of information that might be useful to you or others. Obviously you should do your own research, talk with a doctor about it, etc.
Brain fog and headache are also one of the most common symptoms of long covid. Losing consciousness when getting up sounds like POTS[1] and is also common in long covid. Research is showing that people who are asymptomatic during infection can also develop long covid[2].
In general things like brain fog and headache are also symptoms of burnout and probably lots of other things, so I think it would be pretty difficult to clearly distinguish between them. There also isn't a test for it and it won't show up in standard blood tests. And of course it's also possible to have both. Some form of long covid, even if it is just "light" compared to other people who have long covid, could easily push someone who is already on the brink of burnout over the edge.
Distributions can't take advantage of the system libraries exception, it only works for software that isn't shipped together with OpenSSL. The whole GPLv2 clause:
"However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable."
I use gevent instead of twisted for event-based python. Gevent is a lot nicer to work with and doesn't make your code less readable in the way twisted does with its callbacks and errbacks. It's also a lot easier to do unit testing with gevent.
There are limited publications about the possible effect of titanium implants, for example https://pubmed.ncbi.nlm.nih.gov/30174768/
