@sundev 👍，了解了，这样确实很方便，我其实和您不谋而合，是在 macOS 下用 http://www.hammerspoon.org map 了 ctrl-h 为上，ctrl-j 为下哈。

是的，我是通过软件 remap CAPS 为 CTRL，但是 CTRL 还是 CTRL

原因有 2，其一是确实用不到 CAPS，其二是我平时用的外接键盘是老式的键位，CAPS 那里就是 CTRL，偶尔我切换到笔记本的键盘时候，也习惯了这个键位。

@zhengdai1990 c++ 开发可以哈。

windows 虚拟机里封一个 venv，配上 batch/powershell 调用，打包 zip，得了，不搞 exe 。

Update:

之前的问题不事生产环境，之后没有重现不了了之。

今年又有别的朋友遇到这个问题，找到我，我又看了一下，猜测问题可能出在 traffic pattern 频繁触发了 ovs dpdk bonding 的 流量 shift，shift 的抖动造成了 VM （有抖动敏感的重启机制）内部的重启，而这个 long poll 只是 VM 重启的结果。

下边是 bonding shift 流量的触发条件：高的一边比低的一边差别在几个维度（ delta BW，BW 比例，高的流量超过一个，并且 shift 能降低至少 10%）。

ref: https://docs.openvswitch.org/en/latest/topics/bonding/

> Bond Packet Output¶
> When a packet is sent out a bond port, the bond member actually used is selected based on the packet’s source MAC and VLAN tag (see bond_choose_output_member()). In particular, the source MAC and VLAN tag are hashed into one of 256 values, and that value is looked up in a hash table (the “bond hash”) kept in the bond_hash member of struct port. The hash table entry identifies a bond member. If no bond member has yet been chosen for that hash table entry, vswitchd chooses one arbitrarily.

> Every 10 seconds, vswitchd rebalances the bond members (see bond_rebalance()). To rebalance, vswitchd examines the statistics for the number of bytes transmitted by each member over approximately the past minute, with data sent more recently weighted more heavily than data sent less recently. It considers each of the members in order from most-loaded to least-loaded. If highly loaded member H is significantly more heavily loaded than the least-loaded member L, and member H carries at least two hashes, then vswitchd shifts one of H’s hashes to L. However, vswitchd will only shift a hash from H to L if it will decrease the ratio of the load between H and L by at least 0.1.

> Currently, “significantly more loaded” means that H must carry at least 1 Mbps more traffic, and that traffic must be at least 3% greater than L’s.

@NebulaGraph 谢谢您😊

您好,发了邮件到 hire@ 不知道是否收到 😀。

电视直播的话，你需要的是一个叫电视家的 app

昨天看到 game& watch 已经可以刷系统跑其他游戏了，可惜只有 1MB 的空间。

找一个开源社区，贡献试试？

sso 不只可以用 openid connect （基于 oauth2 ）还有其他方式比如 saml2，kerberos 之类。

推荐 Apple TV/HomePod，iPad 的响应时间长一些。

virsh 是 libvirt 的 utility，和 openstack 没有直接关系。
