It’s a little more than 100€

It’s half as much again! If your budget is that flexible you really should have mentioned it in the original post so that people could give you a wider range of options.

Translate it up by a couple of orders of magnitude and you get “I want to buy a car, I have €10,000 to spend” … “I found one for €15,000, it’s a little bit more but …”

It’s a very flexible language so can find a niche almost anywhere. I know of fintech companies that use it extensively for their back end data processing systems, and I’ve seen some really interesting stuff done with Clojure and Apache Kafka. They’re a good fit for each other - Clojure, as a lisp, is optimised for processing infinite lists of things and Kafka topics can be easily conceptualised as an infinite stream of data.

Also, when combined with Clojurescript, it provides a single language that can be used full-stack, so could drop in anywhere that you might otherwise use Node.

But I think one of the best things about it is the way it forces you to re-evaluate your approach to development. It’s a completely functional language so you have to throw away any preconceptions about OO and finding new ways to resolve old problems is one of the things that should be a joy for most developers, even if it has no practical application.

Give Clojure a go.

It’s a modern variant of lisp that runs on the JVM and has deep interoperability with Java, so you can leverage your existing knowledge of Java libraries.

But as it’s a lisp, it will have you thinking about problems in a very different way.

How did we let this happen?

How could we not have done? When electricity was first being proposed of a way of powering homes and industry we couldn’t even agree on a standard for distribution (Tesla vs Edison). The world’s governments didn’t step in because this was a dispute between private companies. Just like governments didn’t decide whether we should use VHS vs Betamax, or drink Coke vs Pepsi.

And then once a country decided on a standard distribution method they had to pick a voltage, a frequency, and a plug/socket design. Again, there was no real reason for governments to get heavily involved at this point - after all, nobody knew if this new-fangled electricity thing would ever really catch on.

Can we just start again?

Sure. But it will cost maybe hundreds of billions. Maybe more than that. It doesn’t matter which plug/socket design you say is the right one for the whole world, most of the world won’t already be using it (just look at the map!). So all those countries are going to have to change not only the plug on every single appliance in existence in their country, but also every single socket on every wall in every building. And what’s the benefit to the countries that have spent al those billions doing that? Absolutely nothing - the advantage and profits will be reaped by product manufacturers who don’t have to produce a variety of connectors.

Yes, I think that ‘masquerading’ is the key bit to grasp. The MITM Proxy isn’t just intercepting the traffic, it alters the traffic as it passes through.

DigitalOcean’s guides in general are pretty good for all sorts of things, whether it’s a generic discussion of a concept like the ones you’ve posted, or a step-by-step guide for installing and configuring specific systems or software. Even if you’re not using DO as a host, much of what they suggest is still very useful.

That looks amazing. In the last year or two I’ve found a pretty good, reliable dough recipe, but I’m never really satisfied with the tomato sauce I use. Do you have a recipe you stick to?

systemd [is] a niche

Maybe in the wider world of all the operating systems installed on all the computers, but for Linux-based computing it is, like it or not, near ubiquitous these days. And in particular for server systems (and this is, after all, /m/selfhosted), good luck finding something that isn’t systemd-based unless you’re deliberately choosing a BSD or aiming for a system which has ever-decreasing amounts of support available.

what if I’m not using CoreOS?

Podman runs on any distro (or more strictly: any distro that uses systemd). It’s essentially a FOSS alternative to Docker.
