FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

In this example –that focusses on YapDatabase– we wrap a Objective-C method that takes C-blocks of arbitrary types:

| Ruby 2.1.0 in Production: known bugs and patches | |
| Last week, we upgraded the github.com rails app to ruby 2.1.0 in production. | |
| While testing the new build for rollout, we ran into a number of bugs. Most of | |
| these have been fixed on trunk already, but I've documented them below to help | |
| anyone else who might be testing ruby 2.1 in production. | |
| @naruse I think we should backport these patches to the ruby_2_1 branch and | |
| release 2.1.1 sooner rather than later, as some of the bugs are quite critical. | |
| I'm happy to offer any assistance I can to expedite this process. |
