Computer Science at UMBC l CSEE Student Services Office (Advising) l l CSHC (Computer Science Help Center) l l ITE 203 - 206 ITE 201 E Linux Users Group (LUG) l http: //lug. umbc. edu 12
OIT Labs l l l The Office of Information Technology is responsible for all lab computers. On Web at: www. umbc. edu/oit Labs with PCs: l l ENG 021, ENG 104, ENG 122 A, ENG 333 Labs may be on reserve for classes, so plan ahead! Print Dispatch -- ENG 019 (10? cents/page) Hours of Operations l OIT will post outside of labs or go to: http: //www. umbc. edu/oit/classroomtechnology/labs 13
Consultants vs. Tutors l OIT labs are staffed by consultants using software (pine, Internet Explorer, etc. ) l some text editors (xemacs) l operating system commands (Linux) l communicating with UMBC computers (Tera. Term) l 14
Consultants vs. Tutors (con’t) l CSHC is staffed by student tutors l l l Help with homework and projects xemacs and Linux questions ITE 201 E – Hours TBA 15
Hardware and Software Needs l Do I need my own computer? l l If I have my own computer, can I use it? l l No, but it is more convenient for you. Sure, but you will use it mostly to log in to your account or for word processing. Do I need a C Compiler? l No, and you probably shouldn’t buy one. All programming should be done in your school account. 16
Using Your Own Computer: SSH l l We will discuss this in much more detail in future classes. You do not have to download anything at this point!! Tera. Term is a software communications program Must have an Internet Service Provider (ISP) Two sources for Tera. Term software: l l l OIT CD Web: http: //www. umbc. edu/oit/ Consult OIT for help 17
Getting to Know You l This class has students from many different backgrounds and majors. l l ~13 different majors in this section I’d like to find out a little bit about what you know. Please fill out the survey distributed in class. It is also being used in a study to on how to improve CS education (will be anonymized, of course). 18
