7/5     I have a computer at home hooked up to DSL; can I do wireless
        peer-to-peer sharing to other PCs in my house?  That is, can I
        share Net access without an access point?  I think this can work
        if the PC hard-wired to DSL has both a wired and wireless NIC,
        and the wireless NIC provides the gateway IP.
        \_ Buy the linksys dsl router - 4 port 10/100 switch, does nat.  $160
        \_ I think so, although I'm not sure if home DSL works the same way
           as business DSL. I think you'd just install a NAT or a proxy on
           your gateway computer.
           \_ Yes, there will be NAT and DHCP, just like if you were
              sharing out on a wired home network, but:  Can you do this
              for a wireless network *without an access point*?  I believe
              I can, but I want to know if anyone's tried this.
                \_ What's an access point?  Please don't delete this again.
                   \_ In a peer-to-peer if PC1 is out of range of PC2
                      it's too bad.  With an access point PC1 can talk
                      to the access point which can talk to PC2.  Access
                      points also typically function as a link to a
                      wired network.
        \_ most wireless cards have a special peer-to-peer setting which
           works without access point, assuming you know how to set up
           routing.  your dual-nic host will have to forward the packets
           between the nets.  see wireless card "domain" option, usually.
           on linux it is a pain because this is usually an option
           set at driver module load time, rather than a dynamic setting
           with the pcmcia cardmgr.  so you have to stop pcmcia services,
           edit core pcmcia options, restart pcmcia services for any mobile
           computer when you move from access point to peer wireless domains.
           \_ you try this?

5/18    On my Win7 machine, I've been using a PuTTY ssh session to soda as a
        proxy for my FireFox to bypass my company's OpenDNS when I visit
        http://tv.yahoo.com and so on.  It has been working fine for a long while.
        However, in the past couple weeks or so, my FireFox would either take
        several minutes to load the page, or failes to load it after several
        minutes.  I haven't changed any settings on my Win7 machine.  Rebooting

3/29    A friend wants a PC (no mac). She doesn't want Dell. Is there a
        good place that can custom build for you (SSD, large RAM, cheap video
        card--no game)?
        \_ As a side note: back in my Cal days more than two decades ago when
           having a 387SX made me the only person with floating-point hardware,
           most machines were custom built.

4/26    I see that soda has an ipv6 address but ipv6 traffic from this box
        doesn't actually work (ping6 <DEAD>ipv6.google.com<DEAD>, ping6 http://www.v6.facebook.com
        Is this expected to work?
        \_ Soda doesn't have a real IPv6 address.  The IPv6 addresses you see
           in ifconfig are just link-local addresses; any IPv6-capable machine
           will autogenerate these, whether or not it's connected to an IPv6
