Hi Tildes,

I'm looking to introduce my children (aged 10 or so) to simple electronics (blinking lights, simple sensors, ...). I've played with Arduino in the past, but I see that there are now many competing options: Arduino, cheap rip-offs, RPi zero, adafruit, ESP32, ... It's easy to get lost!

Which do you recommend? Ideally, I'd like something cross-platform and open-source, easy to set up (ideally a kit with everything included), and of course not insanely expensive.

Edit: thanks everyone for the good advice! There are so many good options...

Please just try to provide fair warning of spoilers if you can.

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!

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

Timasomo is Tildes' Make Something Month: a creative community challenge that takes place in the month of November, where participants from our community self-select creative goals to achieve.

Timasomo 2021 is now officially complete! Participants will be posting their creations and efforts in this thread as a showcase! Comments and feedback from the wider community are both welcome and encouraged! Let these creators know what an awesome job they've done!

Creators: In posting your showcase:

• Give your project a title, and use the # markdown to make it stand out in the showcase thread!
• Link to your project in whatever way works best for your project.
• Give a "creator statement" that contextualizes what your project is.
• Add anything else you consider relevant! The showcase is yours!

Community:

• Treat this thread like a walk through an art gallery or a museum where you get to see different works on display.
• Comments do NOT have to be in-depth -- it is okay to just affirm that you like/love/appreciate something! (In other threads these might be considered noise, but here they are directly validating the sustained creative efforts of another community member!).
• Make sure any feedback you give is constructive.

Why am I posting this thread?

Honestly, I'm really excited about this. Isn't that enough? :)

What is it?

The World Chess Championship (WCC) is the topmost competition of the sport, and basically determines the best player in the world. It is disputed between the winner of the Candidates Tournament and the current champion. Since his first title in 2013, Magnus Carlsen successfully defended the title on three different occasions and is the undisputed favorite. The challenger Ian Nepomniachtchi does have a positive score against Magnus, but most don't give that much importance, since most of his victories happened when they were much younger. Chess.com combed through the data and gave Magnus 72% winning odds. In terms of style, Magnus is considered a universal player. Nepomniachtchi is generally more aggressive but adopted a more conservative style in the Candidates Tournament.

Since 2014, the WCC happens once every 2 years, alternating with the Candidates Tournament. The current edition was supposed to take place in 2020, but was postponed due to covid. It will happen in Dubai.

The World Chess Championship starts this Friday, November 26, at 16:30 local time, 12:30 UTC.

Where to watch

• Chess.com
• Chess.com Youtube
• Chess.com Twitch
• Chess24

• FIDE Youtube
• FIDE Twitch

In the United States, the NBC over-the-air television channel will broadcast daily 30 minutes highlights.

The players

Time controls

In chess, time controls determine the time each player has to make their movies. A time control of 10 minutes means that each player has 10 minutes to use throughout the game. There can also be increments, which are added to a player's overall time after each move. For example, with a time control of 10 | 5 each player starts with 10 minutes to make their moves, and automatically gains 5 seconds on the clock every time they make a move.

The time controls for the World Championship matches may seem a bit complex at first. This is just for reference, if you intend to follow the games online, I'm certain that the commentators will make sure to remind you of these details.

The table above means that, on stage 1, each player has 120 minutes to make their moves. On stage 2, they have 60 minutes. On stage 3, each player has 15 minutes, with an addition of 30 seconds after each move.

Format

• Draw by agreement is only allowed after the 40th move (it used to be the 30th).

• There will be 14 standard games (it used to be 12). The first to achieve 7½ points will be World Champion.

• If, after the 14 games, the score is equal, there will be tie-break games in that order, with the subsequent tie-break only being disputed if the previous one maintained the tie.

  1. 4 rapid games of (TC: 25min + 10s)
  2. Best out 5 blitz games (TC: 5min + 3s)
  3. 1 armageddon game.

Scoreboard

Magnus won on round 11. Rounds 12 to 14 will not be disputed.

Schedule

All games, as well as the closing ceremony, are scheduled to 07:30 AM EST / 12:30 UTC.

This will be updated with the results for each match, as well as the sum of the overall points. I will also try to sum up some experts commentaries for each selected games. Adding notes to every game would require more effort than I initially thought! I'll create a top comment with links and basic info on each game, but will not be adding personal notes to all of them. Feel free to add your impressions to the top comments. Thanks!.
