So, it's clearly not a problem with Temple's connection to the outside world. Those machines are just THAT SLOW. Blah. They're that bad even when you're in the lab, since the people remotely connecting are using the same machines that people are sitting at.
This is crazy. I just timed out that there's something between 1 and 5 minutes latency between when I type my command and when it displays on my terminal.
It's the Latency, Stupid. This is completely unrelated to the rest of this post, but I thought it was an interesting rant. You probably won't. :-P I wonder how good modern DSL/Cable modems are in that respect, nowadays. The paper was written in 1996.
 djrust, weren't you supposed to show me a paper on why Java is so slow?
Hm. 10 minutes of work left. I was going to design some classes to make my forms project easier, but I guess that'll be exnayed. :-P
Ah, good! gmake and ./lab1 finally finished. My program is producing the same output. Given my luck with this not too complicated lab, it is entirely likely that when fed another graph it will display a small elephant. However, for this graph, I have success so I can sleep a happy person.
It's amazing how slow these Solaris machines are. I think they just got them last semester or so. Maybe it's because they have X11 forwarding turned on. Or, maybe because they don't have the "automatically pop you over to another host when you ssh in" mechanism they have set up on lucas. The more I use the system, the more it feels like we're all connecting to one server and all the machines in the lab are just dumb clients. However, who(1) makes me think otherwise.

Astro is fast. Very fast. On the other hand, astro has all the fun toys turned off. Like.. uh.. less(1). :-P
Um. Yeah. I seriously doubt anyone's read this far, and I don't need to kill any more time, so I'm going to stop writing now. |
