HN discussionThis might be shocking to some, but when a researcher receiver a federal grant (for example), the university takes a significant cut which they refer to as Facilities and Administrative (F&A) costs [1]. The F&A covers the so-called "indirect" costs of conducting research on university facilities: buildings, utilities, admin and accounting, support staff for compliance with federal regulations, etc. Each university h…

HN discussionI published a paper comparing navigation time with a canvas-based editor (Code Bubbles) vs. traditional tab-based editor (Eclipe) vs. a carousel-based editor (Patchworks, a tool I designed). We found the canvas provided too much freedom. https://austinhenley.com/pubs/Henley2014CHI_Patchworks.pdf

HN discussionEvery word you wrote is true. It's all still true if you replace "DSL" with any project and "Boring Old Language" with the competitor. This is the stopping at 90% problem somebody just posted a link to in another thread. edit: https://austinhenley.com/blog/90percent.html

HN discussionA bit of a plug, but for my senior project, my team is working bringing Patchworks (slide 80) to Atom. It's currently not open source (but will be after completion of the project).

HN discussionI spent nearly a week of my Microsoft internship in 2016 adding support for Source Depot to the automated code reviewer that I was building ( https://austinhenley.com/blog/featurestheywanted.html ) despite having no idea what Source Depot was! Quite a few devs were still using it even then. I wonder if everything has been migrated to git yet.
