Hello – I'm Omar. I've been interested in new computer interfaces and new ways of programming (aren't these the same thing?). I've worked at Dynamicland (check out ⭐️Geokit) and at Khan Academy.

Among other things, I'm the creator of ⭐️Screenotate, a tool for macOS and Windows which captures the text and origin (URL, window title, ...) whenever you take a screenshot.

I also made ⭐️TabFS, a browser extension that exposes your browser tabs as virtual 'files' on your computer (so you can manipulate them like any other files).

Get in touch if you want to talk or work together—

hmm

I also tweet a lot about computers these days, on topics including:

• wanting provenance everywhere, throughout the computer, whether you're programming or looking at data or typing or taking a screenshot or whatever; knowing how the thing was made / the soil that it grew in / the context in which it's actually valid
• getting functionality 'for free' from the architecture of the computer system
• how end-user programming can simplify & improve systems, empower users, remove the need for 'configuration'
• against separating 'content' and 'presentation' / what does "serving a function" really mean?
• the role of dread in computing; weird, intense, consequential feelings that are produced by seemingly-incidental details in how the software works
• how we should lean into existing user 'folk practices' like taking photos, taking screenshots, and using hacked-together spreadsheets
• programming environments as culture; knowledge (of programming, of reading and writing, etc) as something that exists in a community, not a property of one person's head; how the social (imitation) drives what people want to learn and make
• how the grain of underlying materials and the tractability of doing certain things ends up silently guiding what people do (not necessarily a bad thing -- it can be a source that you can learn from!)
• speculation on how software could have more physicality, spatiality (1, 2, etc), vitality, how a 'toy' might be better than an 'app' or a 'game'
