@Gargron I'm about to do some work on QOTO's fork of mastodon, specifically some docker containers geared towards beta testing. Is that anything that would be useful for you that I could share?

Interesting fact: The Dutch government issues a Burgerservicenummer (BSN) to all its residents. This is required whenever you wish to order burgers in a restaurant throughout holland, including at McDonalds and Burger King locations.

OK I kinda made this one up :) but BSN is a real thing :)

I just started to show symptoms of a cold today (Rhinovirus). I haven't had a cold in years now. I feel like my immune system is getting an update.

@timorl Correct, I'm very impressed :)

Rule number one to solving any problem: use graphs (as in Graph Theory)

The jars with papers inside represent a permutation, every piece of paper points to the next jar in the permutation, say we number the jars from left to right. As all permutation, this one can be represented as a collection of cycles. Two key insights about these cycles:
1. Every cycle containing the jar numbered $k$ neccessarily contains the piece of paper with $k$ written on it, otherwise it wouldn't be a cycle.
2. At most one cycle has length greater than $50$.
With these insights the solution is simple. Your assistant looks at the whole permutation, and if any of the cycles has length greater than $50$ they switch the pieces of paper to break the cycle in half. They do nothing if there are no big cycles. Now you get told the number you are looking for and go for the jar numbered with it. Afterwards just trust the pieces of paper to lead you to the correct jar.

Thanks for this puzzle, solving it gave me a very needed confidence boost. *smugness incoming* Especially since I didn't even need to use paper.

The ECG of the #card10 can also be attached to other body parts. E.g. you can detect eye movement when attached to the head: #cccamp2019

She is literally the only decent candidate on the left and cant even qualify for the debate... the democrats pension for self destructive behaviors never ceases to amaze me.

Some people asked me to share a lvery difficult yet simple logic puzzle that has stumped my friends. It is also my favorite interview question.

First off some background. The problem is not a trick question, as much as it may seem like one. There is no play on words, no hidden exception. Everything in this problem is exactly how it is presented and the answer doesn't rely on any slight of hand. Take this puzzle at face value.

Also **ALL ANSWERS NEED CONTENT WARNINGS** I do not want you spoiling it for others. This goes for questions and hints too.

Now on to the puzzle:

There is a room with 100 jars with lids on them all in a row. There is also a stack of papers, 100 papers each labeled 1 to 100. The papers are shuffled and one paper placed into each pot randomly.

You and your assistant are in an a joining room. Your assistant is allowed to enter the room, look in all 100 pots, and if they wish they can pick any 2 pots and switch the paper in them. They can only do this one time, they do not have to do this they can choose to also do nothing. At this point they leave the room, without talking to you.

Next, someone tells you a random number from 1 to 100. Your goal is to enter the room and open a pot tht has that number in it. You are allowed to open, at most, 50 of the pots.

Whatever process you use to open those pots must **guarantee** that by the time you open the 50th pot that the number you were given will be found. Obviously your assistant didn't know what the number is at any point.

What rules do you give your assistant, and what rules do you follow, to ensure you are successful?

I gave my buddy Jor a logic puzzle problem. Same one I give new programmers on interviews. Despite the answer being simple, the problem itself is hard for everyone I ever gave it to. In fact no one has ever been able to solve it within an hour and only one person has ever been able to solve it at all that I personally knew.

Anyway Jor got so frustrated he angrily went to the corner as he worked out the problem.

Here is my ( ) list. We have a lot of new faces on I just have to share, and a new few friends from around the fediverse. Plus some old friends too.
