Your #DFIU category today is OG HACKER SHIRTS This Ron Rivest 1987 cipher, illegal to export from the US (mathematical munitions), fit on 3 lines of Perl and adorned t-shirts as a form of civil disobedience before becoming the WEP protocol's greatest weakness
In trying times like these, it’s important to know that true innovation comes through simplicity. Therefore, team #DFIU has bravely chosen to simplify our logo. Please direct all complaints to @winnschwartau. Please direct all congrats to @lintile.
