I've noticed the same thing as a contractor. I only seem to get hired if I am one of the first few bidders. Otherwise there is a slim chance I will get noticed.
"Push-pull-rebase bottleneck: if you rebase and push and someone beats you to it, you have to pull, rebase, and try again. This gets worse as commit rate increases and people do needless legwork. Facebook has moved to server-side rebasing on push to mostly eliminate this pain point. (This is part of a still-experimental feature in Mercurial, which should hopefully lose its experimental flag soon.)"
What if there are merge conflicts?
I don't know about Mercurial, but in Git there are tons of cases where rebasing cannot happen automatically.
I have always wondered why nearly every time I enter a convenience store in Japan sure enough there are 2-5 people standing there reading magazines for seemingly a really long time. I always wondered why don't they just buy it and at read it at home?
The problem I see with using docker for development is, you still need different rails environments(development, test, etc.), the dockerfiles I've been making are for production, and I'm not sure if they would work in the other environments. Also you have to use tons of commands (rake, rspec, migrate, etc) which at this point requires entering the container, which you really shouldn't have to do unless there is a problem with the container itself.
KiwiIRC uses this protocol apparently. I asked the author about it and they said they have worked out special arrangements with some networks to implement it, and accept connections exclusively from Kiwi, I presume? After all, a password is required according to this spec:

I'm kind of wondering how sustainable a pay for screencasts business is. A couple people seem to have burned out on it (railscasts, Gary Bernhardt). I'm not sure if its the expectation of getting something new up every week or two weeks is too stressful or they just run out of material. Is it possible to keep it going without getting sick of it or running out of things to talk about?
Seriously? This crap is so old. SRS is great and I can't believe someone hasn't made a better application than crufty old Anki yet. This is some seriously low hanging fruit here.
I use most of these methods for caching. I have my own little methods for making cache keys. I use Rails.cache all over the place. I have a couple sweepers. What I really struggle is testing this stuff. You really can't do it anywhere other than an integration test, and they're ugly. I mostly just test the sweepers. Anyone have any nice solutions for testing caching, or think its unnecessary?
