Thinking through salts for passwords
No one who's sane stores actual plaintext passwords; instead theyhash the password in some way and store the result, throwing away thepassword itself as fast as possible. There are three ways you can dothis:
- you can hash just the password.
- you can hash some global value plus the password.
- you can hash some per-user value (a 'salt') plus the password.
If you hash just the password, anyone who can somehow gain access toyour password hashes can immediately run them through

投入了很多的努力和很大的熱情，做了一些事，結果是無喜無悲，只有渴睡。
過去的幾個星期，身體像一盞漸次熄滅的燈，意志也如是。

A thought about the speed of IPv6 deployment
The following thought about the push for IPv6 deploymentstruck me recently, so I'm going to dump it here.
One of the problems with IPv6 is that its major benefit is to expandthe available address space, and the expansion of address space doesn'tbenefit people who are already on the Internet. Instead they are beingasked to do a great amount of work for the benefit of other people,which rarely goes down very well.
(The people who are already on the Internet by and large

Note to self: check for gigabit Ethernet
One thing I should remember is that before I start measuring things likeiSCSI performance, I should check to make sure that I'm actually using agigabit Ethernet connection. Conversely, if I get unexpectedly terriblehigh-level performance, perhaps I should make a point of immediatelychecking the network speed. Especially if the terrible performance isaround 10 megabytes a second.
(This is especially embarrassing when I forget this for the second time.)
This can happen to us for a combination of two reasons; first,
