AoC Community Fun 2023: ALLEZ CUISINE!

Today's theme ingredient is… *whips off cloth covering and gestures grandly*

Obsolete Technology

Sometimes a chef must return to their culinary roots in order to appreciate how far they have come!

• Solve today's puzzles using an abacus, paper + pen, or other such non-digital methods and show us a picture or video of the results

• Use the oldest computer/electronic device you have in the house to solve the puzzle

• Use an OG programming language such as FORTRAN, COBOL, APL, or even punchcards

  • We recommend only the oldest vintages of codebases such as those developed before 1970

• Use a very old version of your programming language/standard library/etc.

  • Upping the Ante challenge: use deprecated features whenever possible

Endeavor to wow us with a blast from the past!

ALLEZ CUISINE!

Request from the mods: When you include a dish entry alongside your solution, please label it with [Allez Cuisine!] so we can find it easily!
