In Java you can't register non-blocking sockets with select. Unless i'm wrong? Thanks,

Yeah so my sockets are set to non-blocking. I think its slightly different in java. It doesn't block when you read or write, if you use select in Java. This is the issue I am trying to overcome.

Hi, I am using the NIO library to make sure my sockets don't block. However, I am having issues with reading and writing, and am trying to come up with a way so that I can complete these operations WITH blocking (So I get all the data). Any clues? Thanks,...

Is it not unfair that the coding framework was released 1.5 - 2 weeks after the project was announced? All that time being unable to start seems like a good reason?

Hi Chris, Are we wanting to find the most direct, or fastest route in terms of timing. Just an example: Say it is 12pm and we are going from Stirling st to Leederville St. Would we take the most immediate route, say leaving at 12.04pm on the Joondalup Line,...

Chris, I have attempted to use these functions. I have a string, then encoding it with utf-8 and then decoding it using the same utf-8 when it is received by an adjacent server. I just retried it to make sure I hadn't made a mistake, but I still have the...

Hi Chris, Hope all is well. I am currently trying to send UDP packets to ports within the computer, however they don't decode the messages sent. I was wondering if you have any suggestions on how to go about this because I've been stuck on this for ages....

Hi Chris, Could you provide us with some indication of what sort of questions to expect in the final exam since the format isn't as usual. Thanks,

photo Re: Will same startstations.sh file be run more than once? (all 4)
Sat 9th May, 11:46am, ANONYMOUS  O.P.
Hi Chris, Correct me if I'm wrong, but in Python, reusing addresses allows use of connection to same port and address if another process of the server is invoked. Would you happen to know a way around this? Or suggest an alternate option? Thanks,
photo Will same startstations.sh file be run more than once? (all 4)
Fri 8th May, 1:40pm, ANONYMOUS
Just wondering if the same startstations.sh file be run more than once? If so, that would mean one station has multiple servers running? Does that mean we have to determine if a server is already running?
