This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.
You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
| 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. |

| 检测 两组任意(不限个数 不限花色) 的扑克牌, 混到一起后能否构成任意长度(大于1 小于15)的顺子. | |
| A可表示1或14,小王可表示1--5,大王可表示1--14 | |
| 说明: | |
| 1 我微博里说 小王代表 1到9有误, 我这边实际遇到的场景是 小王代表 1--5 (当然 这个无所谓) | |
| 2 牌是可以有重复的 : 例如 可以 4个小王 9个大王 等等, 可以理解为是从无数副扑克牌当中随意抽取出两组 | |
| 3 组成的顺子 可以不是5张 , 其实严格说 就是 等差为1的等差数列 | |
| 4 能且只能组成一组顺子, 组成顺子后, 牌没有剩余 |
