R/place

R/place is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand R/place rather than just read about it. In short: r/place was a recurring collaborative project and social experiment hosted on the content aggregator site Reddit. Originally launched on April Fools' Day 2017, it has since been repeated again on April Fools' Day 2022 and on July 20, 2023.

Key takeaways

  • R/place belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect R/place to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of R/place from memory before moving on to harder problems.

Reference excerpt

r/place was a recurring collaborative project and social experiment hosted on the content aggregator site Reddit. Originally launched on April Fools' Day 2017, it has since been repeated again on April Fools' Day 2022 and on July 20, 2023. The 2017 experiment involved an online canvas located at a subreddit called r/place. Registered users could edit the canvas by changing the color of a single pixel with a replacement from a 16-color palette. After each pixel was placed, a timer prevented the user from placing any more pixels for a period of time varying from 5 to 20 minutes (depending on whether the user had verified their email address). The idea of the experiment was conceived by Josh Wardle. Over a million users edited the canvas, placing a total of approximately 16 million pixels, and, at the time the experiment was ended, over 90,000 users were actively viewing or editing the canvas. The experiment was commended for its representation of the culture of Reddit's online communities, and of Internet culture as a whole.

Overview The experiment, during the 2017 edition, was based in a subreddit called r/place, in which individual registered users could place a single colored pixel (or "tile") on an online canvas of one million (1000 x 1000) pixel squares, and wait a certain amount of time before placing another. In 2017, the waiting time varied from 5 to 20 minutes throughout the experiment, and the user could choose their pixel's color from a palette of sixteen colors. The 2022 edition started with the same size and colors as 2017, but the canvas was later expanded to four million (2000 x 2000) pixel squares, and the palette gradually gained sixteen more colors for a total of 32. The 2023 edition also started with the same size as the 2022 and 2017 editions (1000 x 1000), and started with 8 colors. It was later expanded to 2 million (2000 x 1000) pixel squares, with 16 colors, then it expanded to 6 million (3000 x 2000) pixel squares, with 32 colors. Reddit administrators have the ability to place as many pixels as they want and can use this ability to remove offensive content from r/place. Guidelines have outlined this content as nudity, hate speech, targeted harassment, or otherwise objectionable content. This power was illustrated in 2023 when messages expressing violence towards Reddit CEO Steve Huffman as well as some sexual imagery was removed.

History

2017 experiment

The early hours of the experiment were characterized by random pixel placement and chaotic attempts at image creation. Among the first distinct sections of the canvas to emerge was a corner of entirely blue pixels (named "Blue Corner") and a homage to Pokémon. As the canvas developed, some established subreddit communities, such as those for video games, sports teams and individual countries, coordinated their user efforts to claim and decorate particular sections. This frequently created conflict between communities competing for space on the canvas. Overall, thousands of communities were involved. Other sections of the canvas were developed by communities and coordination efforts created specifically for the event. Several works of pixel art sprouted from the collaboration of these communities, such as fictional characters, Internet memes, flags, and recreations of famous pieces of artwork such as the Mona Lisa and The Starry Night. Several self-declared "cults" also formed to create and maintain various emblematic features such as the (black) void, engulfing art in nothing but black, the green lattice, the aforementioned blue corner, and a multi-colored "rainbow road". At the time of the experiment's end on 3 April 2017, over 90,000 users were viewing and editing the canvas, and over one million users had placed a total of approximately 16 million pixels. An analysis found that the final version of the 2017 experiment consisted of art from over 800 communities. r/place was commended for its colorful representation of the Reddit online community. The A.V. Club called it "a benign, colorful way for Redditors to do what they do best: argue among each other about the things that they love". Gizmodo labelled it as a "testament to the internet's ability to collaborate". A number of commentators described the experiment as a broader representation of Internet culture. Some also commented on the apparent relationship between the makeup of the final canvas and the individual communities within Reddit, which exist independently but cooperate as part of a larger community. Newsweek called it "the internet's best experiment yet", and a writer at Ars Technica suggested that the cooperative spirit of r/place represented a model for fighting extremism in internet communities. The experiment did receive some criticism for the lack of protection from bot usage where users used scripts and macros to automatically draw on the canvas.

Worked examples

Example 1 — a first encounter with R/place

Start with the simplest possible case. Write down what R/place claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to R/place before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about R/place ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of R/place

In research
R/place appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses R/place in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
R/place is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2017 in Internet culture, 2022 in Internet culture, 2023 in Internet culture, so understanding it makes those chapters shorter.
In everyday life
Look for R/place outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is R/place in simple terms?

r/place was a recurring collaborative project and social experiment hosted on the content aggregator site Reddit. Originally launched on April Fools' Day 2017, it has since been repeated again on April Fools' Day 2022 and on July 20, 2023.

Why does R/place matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study R/place?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
