I found this whole file randomly looking through a Terry Pratchett ftp directory on, if I recall, an MIT machine, back in 1995 or 96. I luckily saved a copy, as I haven't been able to find it since...

I know a programming joke about 10,000 mutexes, but it's a bit contentious.

Q: What’s wrong with this code?

NSLock* arrayLock = GetArrayLock();
NSMutableArray* myArray = GetSharedArray();
id anObject;

[arrayLock lock];
anObject = [myArray objectAtIndex:0];
[arrayLock unlock];

You have a stream of bytes in char array buf[]:
00 00 00 0A 68 65 6C 6C 6F 77 6F 72 6C 64

You know the bytes follow a protocol with this spec:
<1 byte> message type (0 == hello, 1 == goodbye)
<3 bytes> message length
<N> message content (UTF-8 characters)

Determine if this is a hello message, and, if it is, print the content as a string to stdout.
