Very well written. I’d only change something about this paragraph:

• Operated without production interruption even with frequent team member exit during critical phases of operation

Sounds like people were quitting on you because of terrible work conditions you fostered. An alternative could be:

• Operated without production interruption even with occasional unexpected or planned team member absences during critical phases of operation

You can implement public or semi public ledgers without Blockchain. That’s what banks are doing already by sending huge CSV files internally and externally. Blockchain is not a technology of zero trust. It’s close to the opposite. You trust a few peers and blindly trust everyone they trust. That way you trust a network that you know nothing about and if the network decides on a common truth that you are convinced is incorrect, there is nothing you can do about it. The consensus always wins and there is no single entity to complain to and get it fixed. This is great for making sure that many actors need to be bad actors in order to have the whole system fail. It’s bad if you don’t trust anyone and want to make sure that your standards are always observed. From a technology standpoint I love the concept of Blockchain. But use cases that are not forced are few and far apart. Too few for the amount of hype it receives.

Is there a difference between regulations regarding eggs between the US and Canada? Eggs in the US are dirt cheap because almost nothing surrounding poultry is regulated. I’m happy to pay the premium in Germany for minimum living conditions, antibiotics restrictions, no culled male chicks, etc. but I also realize that not everyone here is as fortunate.

Weird, I’ve never had problems over the past 15 years or so and I’ve been using VPS servers exclusively. Maybe my providers were reputable enough.

I realize my evidence is only anecdotal, but that’s why I started “in my experience”. Also, common blacklists are checked by the services I mentioned.

In my experience, this is nothing more than an urban legend at this point. There are great standards, like DMARC, DKIM, SPF, proper reverse DNS and more, that are much more reliable and are actually used by major mail servers. Pick a free service that scans the publicly visible parts of your email server and one that accepts an email that you send to them and generates a report. Make sure all checks are green. After an initial day of two of getting it right, I’ve never had trouble with any provider accepting mail and the ongoing maintenance is very low.

Milage may vary with an unknown domain and large email volumes or suspicious contents, though.

Maybe the scene is set in the UK.

Everyone keeps saying that but I just can’t see it. The only time my mails were rejected was because I didn’t know what I was doing at the beginning of my journey. Now, whenever I changed my stack or did some major updates the past 20 years or so, I just go to 2-3 sites that analyze my mail server from the outside and tell me if there is anything wrong. The free tier is always more than enough. Just make sure there is at least one service in the list where you send an email to a generated mailbox and have it analyzed. Just looking at the mail server is not enough to find all potential configuration issues.

I aim at a100% score. It’s time consuming the first time around but later it’s just a breeze.

You have to go out of your way to even find Tesla charging stations in Germany. They are comparatively rare and far in between.

Wireguard is very lightweight and it just works. No overly complex setup, tools, matching protocols, algorithms, versions, etc. It just works and it’s simple UDP traffic. It’s the first self hosted VPN that I actually love and that works on all my machines, mobiles, VMs with just a config file to fine tune what should go over the line.

Almost everything has been mentioned already so I just stick with the unusual: I host a private MediaWiki instance for note taking in my pen and paper rounds. It’s amazing once the other players got a bit more comfortable how to use it well regarding templates, categories and articles. My only regret is that I didn’t set up new instances per gaming group.
