The department has reserved rooms for students in some lower-level courses to study together on the exam study day (Wednesday the 14th). For CMSC 212 the room is CSI 3117, which is reserved from 9 am until 7 pm. If you want to study there you may find other students in the same course if you want to work together.

Message from Prof. Vibha Sazawal: Get $20 and help researchers! My student Hailey Lin and I are doing a research study of new C programmers. We are asking participants to do a few short C exercises. The study will take about an hour. We will give each participant $20 as a thank-you!! We can schedule participants anytime in the next 4 weeks (so after finals is fine!).

If anyone is interested, please email Vibha at vibha@cs.umd.edu and/or Hailey at halin@umd.edu.

Project 5 has a one-day extension, to May 2.

A small number of students doing the wrong thing on the Grace machines can cause them to be unavailable to other students, or even to crash. It's especially unfortunate if this occurs right before a project deadline. Therefore please carefully read the following:

• Do not, under Linux/UNIX, use control-z to stop any running program. Control-z may appear to stop a program, but under UNIX control-z actually keeps the program alive so it continues to use machine resources, negatively affecting the ability of others to work on their projects. The UNIX tutorial explains that, under UNIX, control-c is used to interrupt a running program (for example, one with an infinite loop), rather than control-z. To stop the debugger, use its "quit" command, rather than control-z.

• Do not run numerous multiple copies of the text editor Emacs simultaneously, especially shortly before a project deadline, as Emacs is a large program. If you just want to look at a file, use the programs more or less, mentioned in the UNIX tutorial.

• Even if you want to change several files, do not run numerous multiple copies of the text editor simultaneously. The UNIX tutorial explains how to use a single copy of Emacs to edit multiple files, switching between them. Please refer to Section 10.3 of the UNIX tutorial.

• If one of the Linux Grace machines is having a problem and you can't log in via linux.grace.umd.edu, you may be able to log in directly using one of the two specific machine names baby.umd.edu or scary.umd.edu.

Users who don't follow the above may be kicked off the machines by the systems staff, causing to lose all their work in progress; therefore please read carefully and do as requested. If you have any questions about how to use the machines properly, please ask in office hours.

There are still some CMPS Corporate Scholars summer internship positions open with companies this summer, for which students who complete CMSC 212 this semester would be eligible. The deadline for applications has been extended to this Friday. These positions are located at local technology companies; they are all paid and come with a $2,000 scholarship. More importantly, these companies are looking just for Maryland CS students to give them a chance to apply their knowledge and learn new skills. If interested, please consider appling for the OPIS, Freewebs, Figleaf, GlobalNet and Ensco positions at www.cmps.umd.edu/csp/index.htm .

The campus Linux User Group (UMLUG) will be giving a presentation this Wednesday (the 6th) at 6pm in CSI 1121. They will be presenting "cool" things you can do with a Linux desktop, and some "fun" stuff like games and 3d desktops too. Increased knowlege of Linux will be very useful for this course as well as a number of upper-level CMSC courses, so if you have time you may want to consider checking out this meeting.

Welcome to CMSC 212!
