刚才试了一下，PS4 手柄直接 USB 线就可以在 Steam Big Picture 和 GRID 2 里用。只是可惜没有支持震动。

估计 PC 版 + Xbox 360 手柄会有震动。

不是。

感觉今年的升级在有意让 Mac mini 的性能和 Mac Pro 有比较大的区别。

@CaiusLiu 好的。另外一个重复的已经删除。

不要在不同的节点发布内容相同的主题。

嗯，必须找公司申请资源把这个功能做了。

@aveline 关于 proxy_cache_lock 的问题，今天又研究了一下。总算是找到 Nginx.org 官方的 Maxim Dounin 的答复了：

Again: responses are not guaranteed to be the same, and unless
you are using cache (and hence proxy_cache_key and various header
checks to ensure responses are at least interchangeable), the only
thing you can do is to proxy requests one by one.

If you are using cache, then there is proxy_cache_key to identify
a resource requested, and proxy_cache_lock to prevent multiple
parallel requests to populate the same cache node (and
"proxy_cache_use_stale updating" to prevent multiple requests when
updating a cache node).

In theory, cache code can be improved (compared to what we
currently have) to introduce sending of a response being loaded
into a cache to multiple clients. I.e., stop waiting for a cache
lock once we've got the response headers, and stream the response
body being load to all clients waited for it. This should/can
help when loading large files into a cache, when waiting with
proxy_cache_lock for a complete response isn't cheap. In
practice, introducing such a code isn't cheap either, and it's not
about using other names for temporary files.

好想悬赏找人做这个功能。

@geew 如果有 escape 的话，也会发生这样的转换么。

:-)

另外就是，代码的高亮默认是关闭的，如果你希望 HTML 中的代码有颜色，记得在这里打开：

不熟悉 torndb，但是疑问是 torndb 里不需要对输入的参数做任何 escape 处理么？

@julyclyde 这是 Apple 的官方文档里推荐的做法：

3 楼的是官方的方式。

@lzsadam 不会。

有内容的主题我们都不会删除。
