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.

Inspired by @Whom's music and anime threads

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!

Wanted to start a discussion for us GoT fans and give our thoughts on how the first episode played out and what we expect to come. Please delete if unnecessary/unwanted. This is a spoiler zone so you've been warned

I just came across this field of 13 admin-removed comments and frankly it left me feeling rather unsettled. That's a lot of content to just nuke all at once. Contextually, the thread up to that point was genial and non-controversial, so it seems especially odd that there's just this black hole there. What struck me mostly was how opaque the moderation was. There is no indication of what kind of content was removed, why it was removed, or specifically who did the removal or when it happened.

Then I scrolled down and at the very bottom I found what I guess is meant to address these concerns, a comment from Deimos:

Sigh, I saw this thread was active and thought it was going to have an actual on-topic discussion in it. Let's (mostly) start this over.

It's not always clear online so I want to say that I'm not rage-posting or bellyaching about censorship or any of the usual drama that tends to crop up on sites like Tildes from time to time. I trust Deimos' moderation and give this the benefit of the doubt. What I'm actually doing, I guess, is making a feature request about better annotation for removed comments.

Would it make sense to show a note (like Deimos' comment) in-thread at the position of the deleted content? Instead of down at the bottom of the page or unattached to anything relevant? In my opinion some kind of "reason" message should always be provided with any moderation activity as a matter of course. Even if it's just boilerplate text chosen from a dropdown menu.

Also, would a single bulk-annotation for all of the related removals make for better UX than 13 separate ones? I think that would be both easier to read, and easier for Deimos to generate on the backend.

I feel like we may have had this conversation previously, but I couldn't find it. Apologies if I'm beating a dead horse.

My title sucks, couldn't word it better.

So, I hate having to use the tilde char. Doing tildes.net~tildes is much harder for me than tildes.net/t/tildes. It would be cool if tildes also supported using "/t/". I am not suggesting to remove the "~", but make one redirect to the other.
