I have been thinking about this vague memory lately. Somewhere between 2011 and 2013, I used to go on an application on Facebook called "Video Chat Rounds" (article: https://www.adweek.com/performance-marketing/video-chat-roun...). It was an app on which you could video chat with other Facebook users (basically the same thing as Omegle). It used to be an app on the Facebook platform.

Back in the day I was still a kid and thought it was pretty cool to see and talk to people all over the world. There is one thing that is bothering me. I have this memory that sometimes, after I had just been on the app and went back to my Facebook homepage, I was suddenly logged into a random Facebook account from a person I had never heard of before. As a kid, that felt really illegal and scared me.

Now, many years later, I am wondering whether this memory is something which really happened or which I made up. It seems very unlikely you could get logged in as another user (without entering any credentials) on a platform like Facebook. However, I do believe it is a real memory.

My question is the following one: could this memory be real and if so, what did Facebook do wrong?

Last year I created an online order system for my youth movement which enabled us to sell anything we wanted online. This was needed as an alternative to the real-life events we could no longer organise and allowed us to continue financing our activities.

Recently, a man (~ aged 65-80) sent me an e-mail in which he told me he was impressed by the system I created (I guess because it automatically sends a personalized e-mail with his order details). He also told me he was interested in informatics (mentioning Excel and C#) but has lost perspective. He seemed upset about that.

I have been thinking how I can help this kind man to regain his perspective in informatics but nothing suitable has crossed my mind so far. That is why I decided to ask HN. What are fun things to study/create/implement/think about? Or what is something he could do to impress his friends with? Or more general, what seems to be a good way to help him regain perspective?
