What’s Canvas?

canvas is a 48 hour event were anyone apart of the fediverse can contribute to a pixel canvas, one pixel at a time

Sticker's fine, somehow, and already on my ThinkPad. Unfortunately I only got 1, and sc07.shop seems to be down. Oh well.

Where the hell was that envelope stuck...

https://sc07.shop/

Get Canvas 2024 & 2023 prints, and stickers to support various instances!

Over the last 2 weeks, I worked to adapt the code that was used for making the 2023 r/place atlas, adapting it to work with this event, as well as making it work on GitLab and Lemmy.

The site is at atlas.mariusdavid.fr, the lemmy community is !2024lemmycanvasatlas@toast.ooo.

The goal of the atlas is to register the meaning of the elements(/arts/placements/zones) of the Canvas, as well as (optionally) meta element about the element itself (like which community placed it).

It offer both the possibility to create new entry or to edit existing ones.

It is ready to receive your contribution (I’ve already put a few elements I worked on). You can start by clicking the “Draw” button, then drawing the element and filling other informations (all but the title are optionals. The 4 specific kind of links (Lemmy, Matrix, Discord, SubReddit) are just to better format them, but any kind of link can be put in the “Website” box). Once finished, you’ll have a piece of JSON code that you can copy-paste in a post on the above community (not this !canvas@toast.ooo one). A bot will then make an MR on Gitlab, which will allow preview, review and approval. (note that opening the MR might take 10 minutes, and making the preview another 10 minutes. Technically speaking, it work by polling, which is not very efficient for quick reaction time).

The full source code is also available on sc07’s GitLab https://git.sc07.company/marius851000/fediverse-canvas-atlas-2024 and there is also a Matrix room at https://matrix.to/#/#lemmy-canvas-atlas-discussion:mariusdavid.fr (avaible from the general Canvas space).

ps: There is no formal method to describe an entry. I will recommend starting by describing what is presented, then putting more meta information, like which community (or user) placed it, who drew it and this kind of stuff.

Orders ship out a week from now!!

There was an error with the fediverse-auth on the Canvas site where after a certain point new logins started being logged as all lower case which created duplicates of 59 users and were treated as separate users. I have merged all of the duplicate accounts and rebuild the database.

This also means that all of the stats on Canvas Stats are incorrect. The canvas Stats app has been updated with the new data.

You can find the fixed database dump sql file on my github: https://raw.githubusercontent.com/TheRealMonte/data-files/main/2024/canvas-2024-fixed-sql.sql The file is 33,568 kB.

The SQL file has 4 tables:

• users (user_id, username, ranking, total_pixels_placed)
• colors (color_id, color_name, color_hex)
• pixels (log_id, user_id, x_cord, y_cord, color_id, time_placed, is_mod_action, is_top, time_deleted)
• top_cord (top_cord_id, user_id, x_cord, y_cord, count_placed)

The users table includes the rank and total pixels placed for each user. Deleted pixels are not counted. There are 13 users who deleted every pixel the placed. They are still ranked, but their total pixel count is 0.

The colors table includes the color ID, name, and hex which when joined with the pixels table can be used to easly select the color name or hex.

The pixels table includes the username, x and y coordinates, color ID, the time the pixel was placed, if the pixel was a moderator placement, if the pixel can be seen in the final image, and the time the pixel was deleted or NULL.

The top_cord table includes the x and y coordiantes for the coordinate each user placed the most pixels on along with the count.

The only data not included here is the pixel color counts for each user. You an find the pixel color counts for a user by selecting:

SELECT color_name, count(color_name) FROM public.pixels JOIN users on users.user_id = pixels.user_id JOIN colors on colors.color_id = pixels.color_id WHERE username = <username> GROUP BY color_name

Another update to Canvas Stats app. You can now view your pixels you placed during the event in your browser and download the pixels as a png image!

I have updated Canvas Stats with the new data from the sql log. Rankings should mostly be the same as the old data, but your total pixel count will be lower since deleted pixels no longer count. A new feature to the site is you can now see if your top coordinate placed is also another users top coordinate placed, which would mean you were probably battling it out over a pixel.

I am also generating images of individual user's pixels. If anyone is interested, just send me a DM. Here is an example of just the pixels that @rrconkle@lemmy.zip placed:

If you would prefer the background to be black instead of white, let me know in your DM.

Another feature I added was overall stats for the event.

Database Dump

the old system for pixel placement logs was flawed, and someone suggested the brilliant idea of just publishing the database dump, it already has all the information anyway

no ip addresses, or ban logs only pixel placements (with username), pixel moderation logs and palette settings

Canvas Repo - Canvas Timelapse Repo

Hi everybody! I have finished building a web app that allows you to search for a user and view their stats from the event! The app will tell you your overall ranking, number of pixels placed, the coordinate you placed the most pixels on, and how many of each color you placed.

I will probably add more features to the website, but I wanted to get something out there so everyone could see how they did.

Thanks @grant@toast.ooo for providing the data.

Here is the link to the web app.

After I finished working on my drawing, I spent some extra time on the event drawing small custom/abstract flags inspired from generated flags from my flag generator, placed on random locations of tiny available spaces on the canvas. Mainly just to help fill the canvas, but overall, that was a cool and fun idea.

I drew a total of 40 flags, but not all of them managed to survive until the end of the event. So, I double-checked and counted all the survived flags, and in total, there are 34 survived flags on the canvas. If you managed to find all of them, I'll reveal a huge list of locations in the comments!

These are some of the mini flags, for a bit of a hint.

the event has concluded! thank you all for participating!

this has been incredibly fun to run, as it was last year (although there was a bit more hiccups this time around)

⚠ Crossposters: link back to this post as it will be updated with more information ⚠

Event date: July 12th, 2024 @ 4am UTC til ~~July 15th @ 4am UTC (72 hours)~~ July 16th @ 4am UTC (72 hours + 24 hours) (it was extended due to a massive performance issue that caused major downtime)

Future events

I'm planning to host another one next year, so stay tuned 👀

If you have suggestions for canvas 2025 or any other events, post them in this post (thanks Ategon)

Supporting the project 💜💜💜

I have spent a little over 6 months completely rebuilding Canvas from the ground up to support future features, and i would love to work on more fediverse events

poster sales

posters of the final canvas will be sold, if you would like to stay updated with information on those, follow the Mastodon account or send an email to hello@sc07.company 💜

https://sc07.shop/

the shop site will also include stickers for the following instances:

• mastodon.world
• lemmy.world
• blahaj.zone
• toot.community
• toast.ooo
• Canvas 2024

✨ I wanted to have the shop setup before the event ending, but i couldn't get it setup quick enough unfortunately

EDIT: Shop is now live!

direct donations

Donating via Stripe is the best way to donate directly

contributing to the code

canvas is open-source and is on a self-hosted gitlab instance at https://git.sc07.company/sc07/canvas

at time of writing; the gitlab server randomly restarts due to resource limits

Timelapses

i need to rewrite the timelapse script as some people pointed out some weirdness with the other ones (that's also what delayed this post by almost 3 hours)

Data

Database dump: (48mb) https://cdn.sc07.company/canvas/2024/canvas-stripped.sql.txt

Contains pixel placements, canvas moderation actions, and palette colors no IP addresses

chat.fediverse.events

This will stay up as long as i can keep it running for, i'll make some improvements eventually as well

tools (like a canvas atlas)

if anyone is wanting to build something for canvas, i'd be willing to host the project & give it a subdomain of .fediverse.events

just send me a matrix dm, a dm on discord (grahhnt) or an email hello@sc07.company

Special thanks

thank you to the moderators that helped me this year, even with how stressful it was 🔨

Hey everyone! Thanks for participating in Canvas. I wanted to make a thread to collect together suggestions people have that can be worked on before the next Canvas.

Feel free to also throw in suggestions for future Events we can build and run for the fediverse.

Ill be collecting suggestions together and making issues for them in the repository for myself or some other contributors to work on (the projects open source so anyones free to contribute! https://git.sc07.company/sc07/canvas Feel free to reach out to me and I can help get you set up with the codebase)

GET YOUR PIXELS INNNN

3 HOURS!!

https://canvas.fediverse.events/

i would also like to know what countries have participated this year!

i'm planning to sell canvas posters to help fund the project and any future events i would love to run

stickers for the following instances will also be sold to support them:

• mastodon.world
• toot.community
• blahaj.zone
• lemmy.world
• toast.ooo
• Canvas 2024

i've spent a little over half the last year to rewrite canvas from the ground up and it's been very very fun running the event so far, stressful, but fun :)

if you're interested in getting a print, drop your country below so i can calculate everything and make sure it's available

if everything goes to plan the prints should be available after the event ends 🤞

As part of an update that was just pushed you can now enable "New Pixel Pulses" which will make a little circle for a bit surrounding any new pixels that get placed onto the canvas

You can use this to see where activity is happening on the canvas

This was originally made as a userscript by soda_cans and was adapted by me into the actual codebase
