It’s the capability of a program to “reflect” upon itself, I.E. to inspect and understand its own code.

As an example, In C# you can write a class…

public class MyClass
{
    public void MyMethod()
    {
        ...
    }
}

…and you can create an instance of it, and use it, like this…

var myClass = new MyClass();
myClass.MyMethod();

Simple enough, nothing we haven’t all seen before.

But you can do the same thing with reflection, as such…

var type = System.Reflection.Assembly.GetExecutingAssembly()
    .GetType("MyClass");

var constructor = type.GetConstructor(Array.Empty<Type>());

var instance = constructor.Invoke(Array.Empty<Object>());

var method = type.GetMethod("MyMethod");

var delegate = method.CreateDelegate(typeof(Action), instance);

delegate.DynamicInvoke(Array.Empty<object>());

Obnoxious and verbose and tossing basically all type safety out the window, but it does enable some pretty crazy interesting things. Like self-discovery and dynamic loading of plugins, or self-configuration of apps. Also often useful when messing with generics. I could dig up some practical use-cases, if you’re curious.

Generally speaking, fault protection schemes need only account for one fault at a time, unless you’re a really large business, or some other entity with extra-stringent data protection requirements.

RAID protects against drive failure faults. Backups protect against drive failure faults as well, but also things like accidental deletions or overwrites of data.

In order for RAID on backups to make sense, when you already have RAID on your main storage, you’d have to consider drive failures and other data loss to be likely to occur simultaneously. I.E. RAID on your backups only protects you from drive failure occurring WHILE you’re trying to restore a backup. Or maybe more generally, WHILE that backup is in use, say, if you have a legal requirement that you must keep a history of all your data for X years or something (I would argue data like this shouldn’t be classified as backups, though).

Discord gained popularity and maintains it, in spite of the many reasons to avoid it, because of usability and feature richness. Slack, Teams, Matrix, Telegram, they are miles ahead of everyone else in the live-chat space, when it comes to user experience.

This was an interesting article about some tech I’ve never heard of before, but it has little to nothing to do with Discord’s overall success.

If you’re unsure about GUMBIES, you should take a look at this video.

It’s retro-encabulators, isn’t it?

Ooooo, new programmer meme lore.

Name checks out.

rsync, for sure. That’s what I used when I had to migrate a 10TB datastore to a new machins.

A DNS Proxy/Forwarder server? That’s where you would configure how your .internal domain resolves to IPs on your internal network. Machines inside the network make their DNS queries to that server, which either serves them from cache, or from the local mappings, for forwards them off to a public/ISP server.

Nah, I meant switch, as that’s what it’s called in C#-land. See above.

That proposal for matching looks interesting, but not quite the same, no.

Until JS supports switch expressions, nested ternaries will continue to be the most effective way to write multi-state conditionals.

Also, stop using linting tools that prioritize consistency over human readability, and then complaining that the code they generate is not easily-readable by humans.

Option 1, except for the cloud bit. My KeePass file is stored in a restricted shared folder on my home file server, and auto-syncs to my phone on the rare occasion I update it from my desktop.

I know nothing about any of the other alternatives mentioned here, but I’ll pitch in my 2 cents that I am very happy with OMV. Haven’t had to touch it since they day I set it up, maybe 2 years ago. Except one time when I wanted to add a new SSH/FTP account for someone.

In addition to the core file services, it supports running a Docker host, in which I have running instances of Portainer (a Docker Web UI), Transmission (a bittorrent client, woth VPN support, also with a Web UI), and Plex.
