What do we want to try in the next sprint? What could possibly help us reach our goals? What could help us be more successful?

Start

What went wrong in the last sprint? What made me feel uncomfortable? What slowed us down? What kept us from reaching our goals?

Stop

What went well in the last sprint? What helped us reach our goals? What was successful in the last sprint? What do I want to use more regularly?

Keep

If you want more, you can do so by directly specifying TextMate theme color rules

        },

          "scope": "text.markdown.notes.tag",
          "settings": { "fontStyle": "italic" }
        }
      ]
    }
  }

Add 2-factor authentication to your SSH logins

Here’s a very quick example of how to force SSH access to any host in the example.com domain to be routed through a bastion host, bastion.example.com:

Host *.example.com
    ProxyJump bastion.example.com
    IdentityFile ~/user-key

Host bastion.example.com
    ProxyJump none
    IdentityFile ~/user-key

Enforce the use of a bastion host

Configuring SSH for user certificate authentication

$ ssh-keygen -s user_ca -I gus@goteleport.com -n ec2-user,gus -V +1d user-key.pub

Issuing user certificates (to authenticate users to hosts)

If not, use the hostname that you will be using in an ~/.ssh/config file to connect to the server.

If you have DNS set up, you should use the server’s FQDN

Configuring SSH to use host certificates

$ ssh-keygen -s host_ca -I host.example.com -h -n host.example.com -V +52w ssh_host_rsa_key.pub

Issuing host certificates (to authenticate hosts to users)

$ ssh-keygen -t rsa -b 4096 -f user_ca -C user_ca

$ ssh-keygen -t rsa -b 4096 -f host_ca -C host_ca

那既然是使用最后两个点计算，这里又为什么需要 [1m] 呢？这个 [1m] 不是用来计算的，是用来限制找 t-2 个点的时间的，比如，如果中间丢了很多数据，那么显然这个点的计算会很不准确，irate 在计算的时候会最多向前在 [1m] 找点，如果超过 [1m] 没有找到数据点，这个点的计算就放弃了。

irate 是计算的最后两个点之间的差值。

rate 函数可以帮我们用这段时间（[1m]）的总 packet 数量，除以时间 [1m] ，就得到了一个“平均值”，以此作为曲线来绘制。

Conclusions

Inlining in Practice

The other exception is link-time optimization. LTO opts out of separate compilation

Besides #[inline], there are two more exceptions to this. Generic functions are implicitly inlinable.

the compiler implements this by compiling a separate copy of the #[inline] function with every crate it is used in, significantly increasing compile times.

it enables cross-crate inlining.

Rule 9: Use comments to mark incomplete implementations

Rule 8: Add comments when fixing bugs

Rule 7: Include links to external references where they will be most helpful

Rule 6: Provide links to the original source of copied code

Rule 5: Explain unidiomatic code in comments

Rule 4: Comments should dispel confusion, not cause it

Rule 3: If you can’t write a clear comment, there may be a problem with the code

Rule 2: Good comments do not excuse unclear code

Rule 1: Comments should not duplicate the code
