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.'"

For those who are curious

For those who are curious what Freenet is: It's a distributed data store, which is censorship-resistant and allows to publish information anonymously.

Re:Too bad it's Affero

[Sanity]

This is compelling but the use of Affero for the license makes onerous demands of the user. The implicit threat of a code audit is there.

Can you elaborate? Which clauses specifically make onerous demands?

Calculators should be multi-line like this - it's so much easier to keep track of calculations. Similar to LastCalc is InstaCalc on the web and something on the Mac called Soulver which is also very impressive.

Shameless plug: I've been working tirelessly on something like this too for almost a year, and apart from lists and a couple of other minor features, is a bit like LastCalc on steroids:

OpalCalc (for Windows currently).

The screenshots should give an idea of what it can do, but to name a few things: it's even more like notepad, faster, can handle times/dates, and allow words in the sum (like saying "5 oranges * £10 = £50" ).
