Jahiduzzaman Tanvin
Drone engineer and IT expert
Sheikh Ashabul Yamin
IT professional
Both were technologists. Both were killed during the July uprising. This event carries their names because the work they were doing is the work we are asking you to do.
It is also a tribute to Jogajog, the tool that let people reach each other through the nationwide internet shutdowns.
Pick one at registration. You can change it up to the close of registration.
Offline communication, mesh and peer-to-peer networking, SMS and USSD services that work on a button phone, and tooling for low-resource disaster response.
Anything that upholds the ideals of the revolution. Accountability, access to information, civic participation, and the memory of what happened.

Yes. Teams are one to three members, and solo entries are welcome.
No. Register solo and use the team-matching channel to find people.

Yes. Your video and deck may be in Bangla or English. The README should be English or bilingual.
