Because they do have a tendency to improve. Jerry Pournelle used to write regularly about his problems with ATI cards in his column on BYTE. They typically followed the same pattern: install new card; install drivers; see computer crash regularly; upgrade drivers; see computer crash less often; upgrade drivers again; see computer run more or less stably.

Then he'd upgrade to the next shiny ATI card and do it all over again, since the new drivers bore little resemblance to the old ones.

I doubt that the mailing list will show any definition of "trampoline". That word has a specific meaning in kernel programming, such that one would already have a good understanding of the subject before poking around in kernel code.

FWIW, "trampoline" refers to generated bits of code containing jumps to arbitrarily different pieces of code, something that ESR called "an incredibly hairy technique" in the Jargon File.

What do you think ILO/ILOM, DRAC, RSA, etc. do on x86 servers? Those have their own CPU/storage/OS/network to manage the server remotely even if the main CPU gives out the magic smoke. A sysadmin can use it to wipe out and reinstall the server's OS and perform firmware upgrades without even walking into the server room.

What I gather from this is that they managed to print the memory and the circuitry to read/write it. So, instead of requiring a mechanical transport and a magnetic head, you simply connect wires to contacts along the edge of the circuit, and use electrical signals to access the data, eliminating the need for moving components.

My son used to play a silly little match game that he picked up from pre-school when he was three years old. In it, he would take two toys -- cars, action figures, Lego blocks, staple removers, whatever -- hold them in his hands, and ask "Which one are you, X or Y?" After the other person (usually me) answered, he'd act out some sort of epic battle between the two toys in his hands, and then declare one or the other the victor. I always pointed out to him the pointlessness of the game. He didn't care.

Jeff Cogswell's reviews remind me of that game. They're pointless. He doesn't care. And my son grew out of it.

If you're going for speed, you'd be better off serving the HTTP direct from Tomcat and cutting Apache or IIS out of the loop entirely.

Tc-native supports HTTP, HTTPS, and AJP, so you still get native code to handle your sockets whether you want to put a separate HTTP in front of Tomcat or not. The Java-based connectors might be fast, but the native connectors are even faster.

... he then completely does an about-face and deploys the Tomcat on Windows-- a configuration I've actually never seen and which has to give C# a bit of an advantage...

The official Tomcat installer for Windows (as in, the one that you'd download from installs the Tomcat Native Connector, which improves performance considerably. And there's a lot of vertical market applications for Windows that bundle Tomcat.
