Ask Slashdot: Where Can You Get a Good 3-Button Mouse Today?

Edward Coffin Re:hp 3 button mouse (428 comments)

I second the HP DY651A. It was apparently unavailable for a while: all the online stores I looked for it in were listing it as out of stock or unavailable for the last few months of 2014, and it was something like $50 on eBay and the like. However, recently it became available again. I ordered mine three weeks ago and got it a few days later, for under $20 Canadian. Multiple online stores (newegg, NCIX, etc) are listing it for under $20, some as low as $12.

Edward Coffin Re:Whisky not Whiskey (30 comments)

Strangely, the quoted text was apparently not cut-and-pasted, since both the linked article and the IAU page correctly use the word whisky. The incorrect whiskey only appears here.

What's In an Educational Game?

Edward Coffin Open ended (160 comments)

I recommend that you read Brain Rot by Theodore Grey and Jerry Glynn. Among other things, it discusses this very topic. The summary I took away from it is you should make the game open-ended, giving full freedom to the player to go down the wrong paths, rather than being led down the right path.

Interesting snippets:

Software should not be unnecessarily hard to use, but neither should it shy away from or disguise the inherent richness of the subject matter. It should be open-ended, deep, and capable of doing senseless things if asked.

In a continuation of the above point, in a discussion of programs to teach geometry:
If students decide to build a completely useless geometrical construction, the program won't stop them. It lets them discover for themselves that their construction is uninteresting. This is very important: By allowing freedom to go off in the wrong direction, the software is giving students the opportunity to learn.
