LastCalc Is Open Sourced

Sanity writes "LastCalc is a cross between Google Calculator, a spreadsheet, and a powerful functional programming language, all with a robust and flexible heuristic parser. It even lets you write functions that pull in data from elsewhere on the web. It's all wrapped up in a JQuery-based user interface that does as-you-type syntax highlighting. Today, LastCalc's creator, Ian Clarke (Freenet, Revver), has announced that LastCalc will be open sourced under the GNU Affero General Public License 'to accelerate development, spread the workload, and hopefully foster a vibrant volunteer community around the project.'"

    Yeah, you're confusing it with a recursive function definition, I've been meaning to fix that. I guess I'll fire up Eclipse (it's Java, not Lisp)

    Being a user doesn't, but hosting it does. That's the difference between the GPL and AGPL.

    Still looking for an open source equivalent of one of the greatest calculators ever written. It was bundled with OS8. This one "shows you the math". Every kid should have it.

    It's got a really great geek story behind it too. If you don't already know this one, take a minute and enjoy.

    Since you seem to know, can you give a brief description of the difference between AGPL, GPL, and MPL for us common folk please? there seem to be a shitzillion licenses out there but those 3 along with BSD (which is easy to follow, its pretty much a "give credit where credit is due" kinda thing) look to be the biggies but knowing what makes one different (and thus incompatible) from the others is hard to keep up with. I know MPL allows copyrighted images, is that the only difference? Is AGPL mainly focused on hosted code? Someone really should make a handy chart for those of us that aren't programmers by trade so we can easily spot the differences.

    AGPL is like GPL, but with the additional restriction that you must share source code to users when hosting it on a public-facing server, IIRC.

    Before the AGPL came out a BSD-licensed project of mine, webdiplomacy, was used to build a fork site.
    They apparently forgot to credit us, are closed source, and didn't even include the BSD license until they were discovered. Instead of sharing code back they're quite bitter rivals, holding their site hostage for donations and having premium accounts.

    Since the AGPL came out there are several other fork sites that have sprung up, but we all pool code changes, and they all market themselves to different niches (e.g. variants or different languages). Many of them are for-profit and host large communities, but we all share code and benefit from it.
