Free Xbox Live Mutiplayer Replacement - XBConnect

Saturday, April 5th, 2008

Microsoft charge $5 / month for access to their online multiplayer network, Xbox Live. I don’t really think it’s fair since the freaking games cost at least $50.00 each, then you’ve got to pay more to enjoy them to their full extent. I remember coming across some PC client that allowed XBox online gameplay for free, so I went in search for it.

A few posts on forums suggested a program called XBConnect - so I downloaded and installed it. So far, so good - it found my brothers’ XBox and found a bunch of games. Then, a problem. Every time I tried to join a game, “Console Activity” would flash, and then the attempt would time out and the XBConnect game window would close. A problem, indeed.

  • XBConnect’s FAQ mentions that forwarding the port 8602 may improve the situation. Not for me, though.
  • Allowing this port in Windows Firewall didn’t help

I was getting pretty pissed off by now, after about 50 minutes it still wasn’t joining games. Fortunately, XBConnect has a chat room within the program and the people seem to be nice - they helped me. I needed to enable ‘Use WinPCap Library in the general options. That’s all I had to do. Conclusion:

XBConnect Game Window Closes When Connecting - Timeout

Solution:

  • Enable ‘Use WinPCap Library‘ in ‘Tools -> Options -> General Options
  • Forward the port 8602
  • Have fun!

I Are Suck at Implicit Differentiation!

Saturday, March 8th, 2008

As far as I understand, Implicit Differentiation is useful when y’ can’t directly be solved with respect to x, like in this equation:

x² - y³ = 8

The first way to try and get around this is to to transpose the equation, making y the subject, ie:

y = cuberoot(x² - 8 )

At this point, you can solve y’ with respect to x as per usual.

Sometimes, though, you can’t make solve for y.

“In these cases, y needs to be solved as a function of x” - I don’t completely get this - I’m going to ask about it though… Here’s where I get stuck:

Where I get stuck with implicit differentiation…

The answer’s supposed to be 4y!!!
