At one job where I was under-worked but had my back to a major walkway and to my manager’s glass-walled office I put Project Gutenberg txt files in a terminal and any time I might have looked at HN, I did that instead.
I've tried "reading at work" and failed. I was trying to read scientific papers that are only tangentially related to work, and couldn't manage to do it. I attribute that to the fact that scientific papers, like coding, requires a lot of time of "building your mental environtment" so you can't be switching all the time.
I just used “less” to read them, if I were to do it again I’d find something that at least kept my place on program close. I think I only accidentally closed it like once in that three months, but over time it would have been a problem worth solving.
Three novels in three months.
