If you want to use BitTorrent or eMule on pc protected by a Cisco ASA 5505, you have to open some ports on your Cisco firewall in order to download at full speed.

To do this, try these rules in your firewall configuration:

access-list outside_access_in extended permit tcp any interface outside eq XXXX
static (inside,outside) tcp interface XXXX 192.168.1.4 XXXX netmask 255.255.255.255

Replace XXXX with the port number you need to open (e.g. 4662 TCP and 4672 UDP for eMule)

Replace 192.168.1.4 with your pc private lan IP.

The new Jangl is a platform for calling between people who don’t want to share their number, but also between people who can’t know each other’s numbers because they’re not expecting a call.

Jangl users can call anyone with an email address. You just drop your own number and their email address into a form on the Jangl site and you get a local number to call them at. When you call the number, you’ll record whatever message you like. A link to the recorded message will be emailed to the person along with a local number (local to them) to call you back on without revealing their real number.

For further information:  Jangl home page.

Programmers have very particular font needs. A font for programming must be mono spaced, extremely readable, and must sharply distinguish between similar characters, such as capital O and zero and the number 1, capital I, and lowercase L.
