I've been looking at OpsCode's Chef, which seems pretty cool. I was wondering if anyone else had encountered useful tools?
The classic is cfengine. It's been around forever.
CFEngine has indeed been around forever, but the newest version (CFEngine 3) is a complete rewrite from previous versions. The policy language in CF3 is redesigned to make it more consistent and extensible. There's also now, if you are so inclined, a commercial version that has a nice graphical user interface and other enhancements.
There's a whole lot of information about CFEngine at http://cfengine.com/tech
(disclaimer: I work at CFEngine AS)

when our website was infected，we always just change the root password and the mysql password，fix the code where have vulnerability。But I think it is not enough ， does anyone have more advance on it？ I just have no idea that whether he has the backdoor in our system or have other attack that I haven't know about。
The problem is, that after the system was once hacked, you cannot be 100% sure that the hacker did not leave you a backdoor, unless he left a log of what he did.
The best way would be complete reset the system. Re-install the OS and completely rebuild the server. However that might not always be an option.
I would advise you to
Rebuild the system
Check all code using sql in you app to use prepared statements
log the sql for some time and go through it, to see if the hacker tries again and make double sure you get the code he aims at
(original post spoke of injection - not infection)

I've come across the phrase multiple times the past month or so, usually when talking about functionality. Is this any different than saying 'built-in', or carry with it any specific connotations?
From dictionary.com:
a. (Computers) to incorporate (a feature) as part of a
system or piece of software or hardware while it is still in
development: The location-tracking service is baked in the new app.
Security features come baked into the operating system.
b. To include
as an inseparable or permanent part: Baked into the price of the
product is the cost of advertising.
Your assumptions are correct. It pretty much means that you don't have to do anything special to install this functionality. It's built in. Already there.
Other variants are:
Rolled in
Built in
Native

I'm looking for an alternatives to yUML, preferably open source.
Sure yUML is great and I really like it, but I would like to be able to extend it.
I'm also interested in other services in the same direction (diagram generation), but I'm not looking for any (UML)desktop tools.
Some suggestions of textual modeling tools. For instance, take a look at PlantUML
Scruffy can draw some yUML diagrams.
Scruffy-Server is a newly made web server frontend for Scruffy which has a rendering and syntax almost identical to yUML.
At the moment it doesn't have the PDF/Json/SVG(or PS) export options, but those might be coming. On the other hand it is very fast and has a lean interface.
PS: I might a little be biased as I made it.
Perhaps take a look at jsUML2. It doesn't provide a textual syntax for specifying diagram - it provides a js-based api instead. However the api is very easy to use and it's open source so extensible. They have a demo app built using it here.
hth.
Some years ago I've developed an open source alternative based on Graphviz.
It's basic and only work for relationship diagrams, but it can be extended.
The output look is very similar to yUML.

Is mysql license needed for sites like facebook, twitter etc.. i dont know which category they fall into. thats why.
No, they can use GPL which is freely available. They would need to make Software that links to MySQL like a library or is even based on MySQL GPL, too, but as far as I know, they are not doing any of that. Even if, the GPL would force them to pass on the source code to anyone to whom they give the binary. Since they are not giving away the binary to anyone, there would not be a problem either ;-).

I want to use CxxTest for unit-testing in an application. I do not want to be forced to release source code or object files. The LGPL (under which CxxTest is released) is confusing on this issue.
Am I ok? Do I need to do something special?
As long as you're not distributing your tests it's not something you need to worry about.
If money is involved, you need to consult with an attorney. LGPL is not straightforward.
From what I can see, you'll be alright with the LGPL, however,
If it is a derivative work, then the terms must allow "modification for the customer's own use and reverse engineering for debugging such modifications."
