Lecture 22, Tuesday 18 November
Introduction To C
Goal:
Acquire a reading knowledge of basic C.
Concepts:
Basic C control structures, data, I/O
Program organization
Pointers and parameters
Reference:
The standard reference is The C Programming Language by Kernighan & Ritchie (2nd ed, 1988). But this is written for experienced programmers and can be quite terse for beginners.

CS1110 2 November 2010 Developing array algorithms. Reading: 8.3..8.5 Haikus (5-7-5) seen on Japanese computer monitors Yesterday it worked. Today it is not working. Windows is like that.
A crash reduces Your expensive computer To a simple stone.
Three things are certain: Death, taxes, and lost data. Guess which has occurred? Serious error. All shortcuts have disappeared. Screen. Mind. Both are blank.
The Web site you seek
Cannot be located, but Countless more exist.
Chaos reigns within. Reflect, repent, and reboot. Order shall return. Important point: how we create the invariant, as a picture *

CS1110 lecture 5 14 Sept 2010 Testing; the class Object; toString; static variables & methods Reading for this lecture: Testing with JUnit (Appendix I.2.4 & pp. 385--388), the class Object (pp. 153-154), function toString (pp. 112-113), static variables and methods (Sec. 1.5, p. 47). Reading for next two lectures: Executing method calls, if-statements, the return statement in a function, local variables. Chapter 2 except 2.3.8 and 2.3.9.
This reading will some clarify some concepts, such as method parameters, that we’ve had to gloss over so far. Keep your iClickers and a sheet of paper out. A1 (still) due Saturday Sept 18 on CMS; group yourselves by Wed.
Ignore “Extended Until” on CMS
(We have to apply a fake extension and halt grouping to enable iterative feedback on CMS.) * Email re: lab 03, quiz 2, etc. was sent on Saturday. Bouncing emails: cabooserwar, blacktora4546, jfk54, tariq.mozaini, lukeg432, dc.mcmurtry10, khyjhcho.

A decimal point I'm a dot in place Animosity Is no amity

* Lecture 22. Listening to events on a GUI (and development of a loop) Sec. 17.4 contains this material. Corresponding lectures on ProgramLive CD is a better way to learn the material. Why men think “computer” should be a feminine word
1. No one but their creator understands their internal logic.
2. The native language they use to talk with other computers is incomprehensible to everyone else.
3. Even the smallest mistakes are stored in long term memory for possible later retrieval.
4. As soon as you commit to one, half your paycheck goes for accessories for it.
Why women think “computer” should be a masculine word
1. In order to do anything with them, you have to turn them on.
2. They have a lot of data but still can't think for themselves.
3. They are supposed to help you solve problems, but half the time they ARE the problem.
4. As soon as you commit to one, you realize that if you had waited a little longer, you could have gotten a better model.

A Formal Foundation for ODRL What’s ODRL? An XML-based language for writing software licenses. Language specification includes:
syntax
English interpretation of the syntax
Language is freely available. (No copyright or patent restrictions!)
Language has been endorsed by nearly 20 organizations including:
Nokia, a multi-industry conglomerate focused on mobile communications;
DAFNE, a research project funded by the Italian government to develop a prototype of the national infrastructure for electronic publishing; and
RoMEO, a research project investigating the rights management of ‘self-archived’ research in UK academic community.
Bottom Line: ODRL has a significant widespread impact on rights management.
Problem: No formal semantics = Language is ambiguous ODRL is ambiguous.
In ODRL, we can write `if Alice is not permitted to download file A, then she may download file B’. Suppose Alice is neither explicitly permitted nor explicitly forbidden from downloading file A, may she download file B?
In ODRL, we can write `Alice may download file A, if she does actions a1 and a2 in order and does actions a3 and a4 in any order. Suppose Alice does the action sequence a2, a1, a3, a4, a2. May Alice download file A?
In ODRL, we can write that Alice may download file C, if neither of the above policies hold. What does this mean?
The ODRL document says that the language supports revocation, but doesn’t say who may revoke what.
Bottom Line: ODRL is under specified. As a re...
