#5 楼 @springwq 太恶毒了

#3 楼 @springwq 黄牛党每年都有，今年这么甚？

#1 楼 @springwq 是整点放票，但是每年也没这样啊，25,6 都还有好多票呢

#30 楼 @nxbtch 单次一页抓 10 条，有一些可能没有，120ms 左右，因为业务原因，有数据库写操作，影响性能，单单抓取和存储的话，速度还能快一点

#25 楼 @winnie

sidekiq 默认会开启 25 个线程，但是 perform 还是一个一个的执行，可能是我的写法有问题吧，再找点资料看看

#21 楼 @wppurking 兄台可否发我一份，I can't climb over the wall, [email protected], tx!!!

#23 楼 @wppurking

#21 楼 @wppurking 没东西呢？ Google Drive The app is currently unreachable.

#11 楼 @winnie #10 楼 @huhongda

指条明道，我试了一下 sidekiq，多线程要怎么写，我看了源代码，也没看明白怎么搞多线程，倒是有个 sidekiq_pro

#2 楼 @huhongda sidekiq 多线程怎么搞，没查到相关资料

#3 楼 @wppurking #2 楼 @huhongda #1 楼 @winnie

看来 Sidekiq 值得一试，Sidekiq KO Resque

Resque:

Pros:

does not require thread safety (works with pretty much any gem out there); has no interpreter preference (you can use any ruby); Resque currently supports MRI 1.9.3 or later loads of plugins.

Cons

runs a process per worker (uses more memory); does not retry jobs (out of the box, anyway).

Sidekiq:

Pros

runs thread per worker (uses much less memory); less forking (works faster); more options out of the box.

Cons

[huge] requires thread-safety of your code and all dependencies. If you run thread-unsafe code with threads, you're asking for trouble; works on some rubies better than others (jruby and rubinius are recommended, efficiency on MRI is decreased due to GVL (global VM lock)).

#5 楼 @xiaogui 这么机智，我要举报你

感觉页面布局不是很好，header 占的地方太大了，宽屏四列微多，左右两边的东西有点碍眼。个人拙见，美女 ui 会不会不高兴，哈哈

#19 楼 @dog_pan 有空过去瞧瞧

#13 楼 @dog_pan 是的，在北京，业余时间在弄这块

或～，速度好快啊，我还在做呢，但是还是要支持的，周末回龙观搞起啊

@huacnlee @rei

赞一个

#3 楼 @outman 推荐自己啊，哈哈

#6 楼 @flowerwrong binding.pry

国际化还没做哦

#18 楼 @lhy20062008 rails3 是公有和私有方法都能调，但是调用私有方法是不合适的，所以 rails4 改成只能调用公有方法，使用 public_send 了

#13 楼 @nagae_memooff 哟，天津老乡，哈哈

你的用的 cdn 吗？使用那个命令，好像要下载 bootstrap 到本地 assets 里面

#11 楼 @rainchen 👍

#8 楼 @string2020 rails3 应该是有漏洞，所以在 rails4 中改进的，我也是在升级 rails4 的时候发现老代码有这样用的，写出来分享一下，并不主张调用私有方法

#6 楼 @raecoo 我觉得也是

一直用 iteye 写博客呢，顶一个

Events firing twice or more

If you find that some events are being fired multiple times after using jQuery Turbolinks, you may have been binding your document events inside a $(function()) block. For instance, this example below can be a common occurrence and should be avoided:

/* BAD: don't bind 'document' events while inside $()! */ $(function() { $(document).on('click', 'button', function() { ... }) });

You should be binding your events outside a $(function()) block. This will ensure that your events will only ever be bound once.

/* Good: events are bound outside a $() wrapper. */ $(document).on('click', 'button', function() { ... })

#25 楼 @bobby_chen 有一亿个用户，每个用户至少关注 100 个人，那就得上百亿得数据了，nosql 上百亿的数据查询估计也不行吧，而且题目要求是关系性数据库，so..
