We have different sites with around 100k users and they all work with normal databases. If most applications can access the db you can use this solution. |
If you just want to do it for debugging purposes look into strace, which is built in top of the ptrace(2) system call which allows you to hook up code when a system call is done. See the PTRACE_SYSCALL part of the man page. |
It should be noted that generally when creating stream based off another stream the new stream will close the one being passed in. So, to further reduce your example:

Generally speaking, you should not put anything into META-INF yourself. Instead, you should rely upon whatever you use to package up your JAR. This is one of the areas where I think Ant really excels: specifying JAR file manifest attributes. It's very easy to say something like:

[Pygment](http://pygments.org/) is a good Python library to generate HTML, RTF, ANSI (terminal-style) or LaTeX code. It supports a [large range of languages](http://pygments.org/languages/) (C, C++, Lua, Erlang, ...) and you can even write your own output formatter. |

How should you go about learning ASP.NET after life as a ColdFusion developer? |

As someone who has spent around 10 years programming web applications with Adobe's ColdFusion, I have decided to add ASP.NET as a string to my bow.

Calling Console.ReadLine() in the delegate is bad because if the user doesn't hit 'enter' then that call will never return. The thread executing the delegate will be blocked until the user hits 'enter', with no way to cancel it.

I think the best approach here is probably to use build scripts. You can have all your code in one location, and by choosing which files to include, and which not to include, you can choose what version of your code to compile. Note that this may not help if you need finer-grained control than per file. |

/dev/rdsk/c0t0d0s0 means Controller 0, SCSI target (ID) 0, and s means Slice (partition) 0.
Typically, by convention, s2 is the entire disk. This partition overlaps with the other partitions.
prtvtoc /dev/rdsk/c0t0d0s0 will show you the partition table for the disk, to make sure. |
If you use malloc/free instead of new/delete, malloc and free won't care about the type.
So if you're using a C-like POD (plain old data, like a build-in type, or a struct), you can malloc some type, and free another. **note that this is poor style even if it works**.

c0t0d0s0 *is* the entire drive. The breakdown is:
/dev/[r]dsk/c **C** t **A** d0s **S**
