Daniel Jalkut is a Mac and iOS indie developer who founded Red Sweater Software in 2002 after seven years engineering Mac OS at Apple. He is best known for MarsEdit, the long-running desktop blog editor he bought from Brent Simmons in 2007, and for FastScripts, a scripting automation utility. For 16 years he co-hosted Core Intuition with Manton Reece, one of the defining podcasts of the indie Apple-developer scene, and he runs the long-form interview show Bitsplitting. He is a fixture of the indie web and micro.blog community, writing about software craft, the business of going it alone, and the texture of a programming life.
Jeff Johnson is a longtime independent Mac and iOS developer who runs Lapcat Software and the Underpass App Company. He is best known for StopTheMadness, a Safari extension that wrestles control of the browser back from hostile websites, and for being one of the sharpest public critics of Apple's privacy decisions, including the 2020 'OCSP appocalypse' that revealed macOS was phoning home unencrypted every time you launched an app. A philosophy graduate turned code archaeologist, he writes a widely read blog dissecting Apple's broken promises and has racked up a long list of CVE security credits across macOS, Safari, iOS, and WebKit.
