What is Local Hack Day: Share?

Local Hack Day: Share is a week-long celebration of sharing everything you’ve learned as a hacker. If you’ve been hacking with us all year, we’re excited to have you back. If this is your very first event, we’ve got a ton of beginner-friendly challenges for you to complete that’ll have you shipping your hack like a pro in no time. You’ll have your pick of technical, design, and social challenges to complete - each with an emphasis on sharing your work. The more challenges you conquer, the more points you’ll earn. Tune in each day to check out the leaderboards and share what you’ve built. To start hacking at LHD: Share, register here. 

What are these Challenges?

Local Hack Day: Share will run from Sunday, March 28th to Monday, April 5th. During this time, you can expect challenges for all skill levels. We will have plenty of both week-long and daily challenges to keep you busy. Week-long challenges will be accessible for the entire week, so you can hack on them whenever you have free time. Daily challenges are only available for 24 hours after they’re originally posted, so make sure you come back each day to see which challenges you’re going to conquer. 

Challenges will range from social challenges urging you to connect with other members of the community, technical challenges that will expand your coding skills, and design challenges to refine your skills as a creator and artist. We cannot wait to see all you learn, build, and share.
