Pixels Camp Forever!

Or... been there, done that, got the t-shirt!

After being postponed three weeks before it was due to happen in March, Pixels Camp v4.0 was cancelled in September due to the still ongoing COVID-19 pandemic and the uncertainty around it for the forseeable future. 😔

But the pixels community is still out there, and lacking a place to gather this year doesn't mean we don't yearn for ways to pick each other out of the crowd (metaphorically speaking, of course). Fancy a free t-shirt? 🙂

What?

We have special Pixels Camp Forever t-shirts ready to be printed and shipped to the first 100 campers that meet the following criteria:

Was approved for Pixels Camp v4.0 or any of the previous editions;
Shows some public proof that they're a proud member of the pixels community.

This offer is valid until OCTOBER 30, 2020 at 23:59. Only submissions considered valid by this deadline will be eligible to get a t-shirt.

How?

You're probably thinking what we mean by "public proof"...

It means posting a photo or video with the hashtags #pixelscamp and #forever on social media. The photo (or video) needs to show you're proud to be part of this community. You can use your imagination or pick one example from this list:

A photo of yourself wearing some item of Pixels Camp swag in public;
A photo of yourself with a Pixels Camp venue visible in the background (LX Factory warehouse or Carlos Lopes pavillion);
A photo from any Pixels Camp edition where you happen to appear (identifying yourself in the photo if not alone);
A photo of some item or location related with one of the Pixels Camp v4.0 sponsors, thanking them for supporting us (they deserve it).
A nostalgic recollection of having participated in a challenge (must be illustrated in some way, pics or it didn't happen);

What social media?

Well, Twitter is our primary social network for event updates, but we understand you may not be active on Twitter and may prefer to post somewhere else and that's fine. You may have to attach a screenshot to the GitHub issue though. 🤔

Don't forget the #pixelscamp #forever hashtags!

GitHub issue?

Glad you asked...

After posting on social media, open a new issue in this repository using the same GitHub account as you used for Pixels Camp. This is how we will keep track of shipping, and also the final proof that you're #oneofus.

The issue template is pretty straightforward except for the shipping address part. The world doesn't need to know your real name and address, and we're a bunch of nerds, so you'll have to encrypt it in a way only we can decrypt it, which means asymmetric cryptography is involved: 💥🤓

Paste this certificate (our public key) into a file called public.crt:

Write your name and shipping address in a file called file.txt;
Encrypt file.txt with a random 256-bit key unique to you:

openssl rand -out random.key 32
openssl aes-256-cbc -e -in file.txt -md sha256 -pbkdf2 -pass file:random.key | base64 > file.enc

Encrypt the random 256-bit key with our public key:

openssl rsautl -encrypt -inkey public.crt -certin -in random.key | base64 > random.enc
rm -f random.key

Place the contents of file.enc and random.enc in the shipping information and shared key sections of the GitHub issue.

Note 1: The shipping address you give us will only be used to send you the t-shirt, we won't store it in our database.

Note 2: If you get errors about unknown options in the above openssl commands, make sure you're using at least version 1.1.1 of OpenSSL. We tested in macOS (homebrew), Fedora 32, Ubuntu 20.04, and CentOS 8.

On our side we'll use our private key (which only a couple of people have access to) with the following commands to see your address:

base64 -d random.enc | openssl rsautl -decrypt -inkey private.key -out decryption.key
base64 -d file.enc | openssl aes-256-cbc -d -md sha256 -pbkdf2 -pass file:decryption.key

How do I know I've won?

When we accept your submission we'll let you know in the GitHub issue itself.

Important note!

Due to logistics constraints, we're only able to ship to within the portuguese territory (mainland and islands). 📦 🚐 🇵🇹
