• Class diagram: how to write down classes that belong to a library?

  - by Michiel Borkent

  I am reverse engineering some Java code into a class diagram. Now I'm wondering how to model classes that are from a library that I didn't design. If I'm writing them down as classes, I should maybe also know what interfaces they implement, etc, and put that in the diagram. How far do I go with this? Is it better to write them down as attributes of my own classes?

• In SQL, can we always write an inner join statement as a main query and subquery if we only want to

  - by Jian Lin

  In SQL, can we always write an inner join statement as a main query and subquery or vice versa if we only want to find the intersection? For example, select * from gifts g where g.giftID in (select giftID from sentGifts); can do a join and show the gifts sent in the sentGifts table, but it won't be able to show the sentTime because that is inside the subquery. But if all we care is to find the intersection, without caring what is being displayed, then we can always convert one to the other?

• iPad: How to let a user write a hand-written note using a Pogo(like) stylus?

  - by MikeN

  How could I let a user jot a quick hand-written note on an iPad using a Pogo-like stylus? (Or by using their finger, some kind of stylus makes it more legible feasible.) Initial thoughts: 1) Open GL canvas? 2) Store the output as a .png/.jpg snapshot of the openGL screen (by taking a screenhot of the iPad? 3) Would the note be limited to one screenshot, could there be a scrollable area notepad to write out a long note?
