The other side of Linux shutdown

A blackout is just a loss of power. Nothing complicated about it. There are obvious human and societal consequences, but as far as the infrastructure is concerned, a blackout usually means that protection devices have been tripped and the system has protected itself from greater damage.

A brownout means that the electric grid (or interconnection), for some reason, can't supply enough power to satisfy the demand, but protection devices haven't tripped yet. It can result in momentary power losses, drops in voltage, drops in frequency, or some generators getting desynchronized with the rest of the grid. If reactive loads (like HVAC motors) go offline momentarily, they can cause spikes in power consumption, which can overload circuits and trip safety devices.

A UPS needs to immediately switch to battery power when there are signs of an imminent power loss. A brownout might cause a consumer-grade UPS to switch on and off repeatedly, which the inverter circuit probably doesn't like.

This channel is run by a real civil engineer, he's released some great videos about the challenges of maintaining an electric grid.

At the same time, I liked .NET's no-nonsense naming of namespaces. When I see something like System.Threading.Tasks, I can immediately recognise that it's a namespace that deals with task-based parallelism. Then you have tokio in Rust and I want to stab the person that came up with the name. Same for clap and serde. They mean nothing unless you already know what those packages do.

What you described is more or less consistent with Schrödinger's views.

In the Copenhagen interpretation, a quantum system is described by a wave function (the probability density of all of its possible states; the cat is maybe dead and maybe alive) until it is observed, at which point it collapses into one of its possible states (the cat is definitively dead or definitively alive).

As far as I can tell, in Schrödinger's views, there is no superposition and there is no collapse, and a system is described directly by its wave function, which changes over time.

But this is all just interpretation. I don't even know where to start looking for empirical evidence that supports one or the other, or whether there's even a point philosophizing about it.

What's a company secret you can share now that you no longer work there?

Our business-critical internal software suite was written in Pascal as a temporary solution and has been unmaintained for almost 20 years. It transmits cleartext usernames and passwords as the URI components of GET requests. They also use a single decade-old Excel file to store vital statistics. A key part of the workflow involves an Excel file with a macro that processes an HTML document from the clipboard.

I offered them a better solution, which was rejected because the downtime and the minimal training would be more costly than working around the current issues.
