Just like digital audio and DVDs, Blu-ray will no longer be a profitable media.

Unless you absolutely need a numerical result, why do you need a calculator for physics?

There is a reason that every write "hello world". There is a reason that it is actually ok to reinvent the wheel, if only to figure out how the wheel works so you can use it better.

I gotta say I cannot believe this hit /. frontpage, are there no more "do it yourself" programmers around?

For me, one of the things I would program into my calculator would be programs what worked out these multi-step problems as well as print out each step. I mostly did it because I hated homework and doing the same problem that I understood already over and over hurt my brain.

I would bet that the "creator" got part of his tune from previous songs he heard, its just that we don't have sufficient records from that time.

Clearly this is encouraging more works to be created.

To be honest I would love to see at least one example of an author who created a culturally significant work pre-1950 who has created another meaningful work in the last 10 years.

If it can't play starcraft 2 natively, then at best its just a utility OS for me. Hopefully it will be able to run under virtualbox though.

When I was in highschool I would write down anyone password I saw someone type into the computer. It was completely by accident though, I didn't mean to carry my notepad and pen with me where ever I went.

I applaud you on recoding/releasing your code as BSD. My previous company did all of their open source work under a BSD license which was (imo) great for both the community and its employees.

I loved doing math by the time I was in 5th grade, so that lead me to doing it on my own time. My mom bought me some higher level math books, in fact that was the only "home"work that I have every enjoyed, and it wasn't even from the school.

I guess my point is that (anecdotally) you can still do math at an earlier age if you choose to, but I do know a lot of people that could not get it till a bit later. I'm talking about algebra+ here, I think pre-8 should know the basics of counting, addition and subtraction.
