#202Now I'm curious, Are there any websites that do something similar to /r/place? (hackathon idea?) Also, reminds be of the million dollar front page [1]. [1] https://en.wikipedia.org/wiki/The_Million_Dollar_Homepage
4chan's moot's previous startup was something called canvas.
That was not realtime nor collaborative on a single pane. It was a "remix" platform where one user created the initial drawing, then people used it as a base and drew around/over it to change it - in a new picture.
It was quite interesting for a little while.

A long time ago, I built http://www.ipaidthemost.com/ , which is kinda related, at least to TMDH anyhow. Far, far less collaborative than /r/place, but similar in terms of staking out ownership.
Similar to https://flashcash.money

#204Earlier quoted context omitted.
I wish I had enough spare cash to take you up on a bet that you could implement this in less than a weekend. Maybe HN can crowdfund paying you for two days at $1000/day to replicate, versus your time and a $3000 rebate if you can't.
My loved ones are out of town, so you're on! I'll do it for the fun of it and the experience. And because I still haven't built anything on top of kafka, but there's no time like now to fix that. The challenge is: Meet the main requirements of r/place: 1000x1000 image, a web based editor, 333+ edits / second, with an architecture that can scale to 100k simultaneous users (although that part will be hard to actually t…
You can simulate the users for load testing. Have them random walk from an arbitrary start point, changing a pixel every 10-20 minutes.

Simulating hundreds to thousands of writes per second via post requests will be easy. Simulating 100k simultaneous readers of an eventstream will be much harder. I don't know of any tools which can load test that many readers. Do you have any ideas?

#206Given the scale described, it sounds like they could have had a single machine that held the data in memory and periodically flushed to disk/DB to support failing over to a standby.
Did you even bother reading the first few paragraphs? They talked about their usage of Redis for this. Next time please read the article before replying.
Perhaps, rather than posting an insult, you should consider the possibility that you misinterpreted my comment?

#208anyone know what framework they used to do visualizations?
https://grafana.com/ for the graphs and https://www.draw.io/ and http://www.fiftythree.com/ for the diagrams.
Re: How We Built r/Place
#209I love write-ups like this because they are such a nice contrast to the too-common comments on Reddit and HN where people claim that they could rebuild FB or Uber as a side project. Something as superficially trivial as the r/Place requires a tremendous amount of effort to run smoothly and there are countless gotchas and issues that you'd never even begin to consider unless you really tried to implement it yourself.…

I'm pretty active on both. What threads/subreddits are you reading?

This was such an amazing demonstration of human collective collaboration. It sort of makes me fee like humans could do anything, even tho the result is sort of in some sense trivial. As well as simply being enjoyed, this could be studied in so many ways. Competition of memes and cultural representations. 'Evolutionary' convergence upon some optimum. Mainstream vs Fringe. Accepted vs Taboo concepts. Implicit spontaneous emergence of behaviour norms for participants: self regulating systems. I also like this timelapse which contains an overview, and then a close up of each of 12 sections ( 333 x 250 ) - https://www.youtube.com/watch?v=RCAsY8kjE3w
