Welcome to the ETC Computing Wiki
Your ETC Desktop computer
Each student is provided with a desktop workstation, spec-ed for the type of work typically required by ETC classes and projects.
A large part of you experience at the ETC centers around teamwork, which implies sharing and shared resources, and we extend that notion to the way computing works here. However, your ETC desktop is one of the few exceptions: it is considered "yours" for the entire time you're enrolled in classes at the ETC.
Your desktop is pre-configured by ETC Computing to include all the software and necessary configuration to do your work at the ETC.
Printing at the ETC
ETC public printers are located on the 2nd, 3rd, and 5th floors. The ETC provides open access to black and white laser printing. Using these specific facilities, you can print anything you need for your academic pursuits at the ETC.
The ETC does not provide open access for any of the department's color printing facilities. Color printing is reserved for ETC project-related and administrative needs.
If you have a legitimate need for color prints please email Steve, and CC your advisor, to make a request. Be sure to give as much lead time as possible. There is no color printer access after normal business hours.

We are not using a proper print server to list and share the printers, but rather a direct TCP/IP connection over LPR or IPP, which helps in that the printers can be added from other networks (such as the wireless network). Directions for adding our printers to your own computers are below...
The department has many, many mailing lists. The lists are structured hierarchically. Also, some lists are mandatory, while others are optional. Normally the only mandatory list is the list for your class (or, in the case of faculty and staff, the faculty or staff list). All the other lists one ends being subscribed to indirectly, because of how the lists are nested.
Here is the primary tree...
Because of the way the lists are nested, a full diagram would have many dimensions. As such we view the other, secondary trees independently below...
Mailing lists for each of our courses are below...
(TA superlist; changes by semester)
Some of the optional lists are below. Because they are optional, there is little nesting since it cannot be assumed all the members of a specific sub-list are subscribed to any of these lists...
Networking at the ETC
For the most part, networking for you ETC desktop PC is already set up, via the building's wired network.
If you have a personal device (laptop, smartphone, game console) you can register it for CMU's wireless network on your own, specifically the "CMU-SECURE" network on wireless. One of the other wireless networks, "CMU" is a legacy network and is not recommended. "eduroam" and "CMU-GUEST" are special-use networks not intended for students. More on connecting to CMU's wireless network is here...
Computer & Network Security
The main thing to keep in mind about the network CMU is that it is an open network. There is no central firewall (well...there is, but it blocks very few things). Every device on the network is connected directly to the edge of the Internet, with a public IP. There is no NAT.
For that reason, security is handled by each device, which is to say every device should run its own, local firewall. CMU has a group of computer security experts on campus called the Internet Security Office (ISO) which is in charge of scanning the network for problems. If you receive a message from them (either from email@example.com or firstname.lastname@example.org) pay very close attention to what that email says. In the case of your ETC desktop PC, we (ETC Computing) will also be notified of any problems.
