Inappropriate: Users being impolite and overly demanding.
Inappropriate: Maintainers (and supporters) insisting that a problem in their publishing process (whether or not they caused it) isn't their problem because the code works.
Both sides had legitimate grievances, and both sides did a poor job of trying to resolve them.
There is code for some of the related papers, if you just want to play around with something, and something pretty similar at that. Here's one: https://github.com/abisee/pointer-generator
I use RescueTime. Productive time is about 90% each month.
The reality is that 100% of my time, if meetings are included, is productive (excluding minimal breaks).
I feel sorry for the people trying to run businesses with all of these employees not working.
I'm a QA engineer. The most experienced QA engineer on a 3-person team (the other two have either more experience with testing but less with development, or vice-versa). I have waaaaay too much to do to get away with not working.
I do empathise with those for whom maintaining a high level of productivity is impossible because of how demanding their work is. I'm fortunate that I have so many different tasks to perform that if I don't have the energy to concentrate on something demanding, I can switch to something fairly basic.
I'm also fortunate in that, for me, problem solving activities are almost always energising. So if I feel like I'm getting burnt out I can dive into one of the tricky but non-urgent problems I hadn't got around to yet.
In this case your correction is better, and would probably be more acceptable to most educated English readers (especially in formal contexts). But the original is still fine, in this informal context.
What you're nitpicking is a common and frequently-taught misconception. You can end a sentence with a preposition. Some elitists in the 17th century tried to make English conform to the rules of Latin and those rules have stuck around even though they weren't necessary in the first place, unlike in Latin where a sentence doesn't make sense if you don't follow the rules.
