    Imagine your computer is a big block of flats and your applications are all people who live in the building.

    Mail sent to the building address alone isn’t going to reach the intended recipient, because the postman doesn’t know what flat to post it to. So they need additional information such as ‘Flat 2C’

    That’s the basic concept of ports. It’s basically additional addressing information to allow your computer to direct internet traffic to the correct applications.

    When an application is actively listening on a port, it means that they are keeping an eye out for messages addressed to them, as designated by the port number. While an application is sending or receiving messages using a given port number, that port number is considered ‘open’.

    Now, all sorts of applications do all sorts of things. Some are for the public to use and there are some that are useful within trusted circles, but can be abused by malicious people if anyone in the world can send messages to it. Thus, we have a firewall, which acts as a gatekeeper. A firewall can ‘block’ a port, denying access to a given group of people, or ‘unblock’ it, allowing access.

    VPNs are a totally different thing. They are literally middlemen for your internet traffic. Instead of directly posting a message to somewhere and receiving a direct reply back, imagine you flew out to Italy to use a post box there and receive replies from there.

    And other countries are relevant to Mango Mussolini being responsible for the pandemic related economic damage in America how precisely? Surely you are not attempting to move the goal posts?

    No, more like you are once again failing to read and understand.

    My entire point, which I have already literally spelled out, is that while Trump was indeed an utter failure in leadership for pretty much all of his presidency, never mind during COVID, GDP is a shit metric to prove Trump’s ineffectiveness in the COVID pandemic, precisely because other countries that did prepare also had their GDP tank, albeit as a direct result of those measures. You can literally see that much on the graph in the thumbnail of this fucking post.

    That is why I suggested using the number of dead from COVID, which is something the US had in alarming fucking numbers for a first world country, directly because of Trump’s fuckery.

    When you learn to accept your blatant attempt to excuse the utter disaster that 45 was is in fact obvious, perhaps you’ll get mocked less.

    I am literally fucking agreeing with you that Trump’s presidency was an utter disaster. I have literally spelled that much out. Time and time again. You are picking a fight where none exists.

    Fucking. Read. Before. Responding

    The US had virtually no one staying home. That is a myth.

    I wasn’t talking about the US. I was talking about other countries. I literally said as much:

    The main preventative measure for most countries was stay at home orders for all except essential workers.

    The spread was the result of failed 45 policy, period.

    Never argued against this.

    When you quite carrying water for the failed response, perhaps you can be taken seriously on other points.

    When you learn to actually read the posts you respond to, perhaps you can be taken seriously at all.

    And most of those were the result of not having any prevention.

    Not true. The main preventative measure for most countries was stay at home orders for all except essential workers. Working from home wasn’t much of a thing back then, so most places were absolutely caught with their pants down. Stay at home orders were unprecedented and completely unplanned for, most managers considered them unthinkable.

    This is NOT me saying those orders were anything except the right thing to do, but it did completely zero the productivity of entire industries.

    Those orders saved lives. And that is the metric we should be using. But since those particular numbers aren’t really knowable, we can instead use number of dead instead.

    Human life is more important than the economy, and I will always lambast Trump for his decision making during this critical time.
