Covering for Whom as she's busy today.

What have you been watching and reading this week? You don't need to give us a whole essay if you don't want to, but please write something! Feel free to talk about something you saw that was cool, something that was bad, ask for recommendations, or anything else you can think of.

If you want to, feel free to find the thing you're talking about and link to its pages on Anilist, MAL or any other database you use!

Previous challenges

It's time for another coding challenge!

This challenge isn't mine, it's this challenge (year 5, season 3, challenge 3) by ČVUT FIKS.

The task is to design a network communication protocol. You're sending large amount of bits over the network. The problem is that network is not perfect and the message sometimes arrives corrupted. Design a network protocol, that will guarantee that the decoded message will be exactly same as the message that was encoded.

MESSAGE => (encoding) => message corrupted => (decoding) => MESSAGE

Corruption

Transmitting the message might corrupt it and introduce errors. Each error in a message (there might be more than one error in a single message) will flip all following bits of the message.

Example:

011101 => 011|010

(| is place where an error occured).

There might be more than one error in a message, but there are some rules:

• Minimum distance between two errors in a single message is k

• Number of bits between two errors is always odd number

According to these rules, describe a communication protocol, that will encode a message, and later decode message with errors.

Bonus

• Guarantee your protocol will work always - even when errors are as common as possible

• Try to make the protocol as short as possible.

After all this time watching cryptocurrency from a distance, I have finally seen a real world use case.

Marijuana is legal in this US state, however national banks are not allowed to service the marijuana industry due to federal law. Therefore all card processing is not available to the retail outlets. It’s only cash transactions at the retail level.

Until today. Today I was asked if I wanted to pay with a debit card. When I asked how, he said they used litecoin. So I imagine that the card is being run by a company which then converts it to litecoin to pay the merchant. Anyone have any clue on what that might cost the merchant as far as percentage?

I thought I would share this because after hearing all hype rollercoaster regarding cryptocurrency, I have finally seen a somewhat legitimate use of it in the real world.

Do you see any other use cases of crypto out in the wild these days?

it's apparently been awhile since we had a proper one of these on tildes (we've had a few mental health related topics but nothing direct like this), and seeing as the site has grown a bit (to say the least) since the last one there's probably some utility in a new one of these. share your experiences/whatever you've found helps/etc. i think this is pretty straightforward.

What have you been playing to this week? You don't need to be playing the latest games, nor do you have to write gigantic essays. This is just a space to talk games!

Feel free to give recommendations, thoughts, opinions. Chat about playstyles and habits! Reminisce about games and mechanics long gone, or coming back!
