You may not even realize it, but your typical spreadsheet application is actually a very small fishbowl. Sure, you're sitting there in your little plastic castle, happily inputting your data into rows and columns, but if you ever wanted to really break out of the box and perform hardcore data manipulation and calculation, you're going to bump into a wall faster than you might think.

Resolver One is a brilliant application that combines the power of the Python programming language with the ease and simplicity of a spreadsheet. You start using Resolver One as you would any other spreadsheet application, quickly realizing that, as you implement your formulae within each cell, Resolver One is dynamically generating Python code that gives you the results you need. You can study the Python code and tweak it to make it do what you need it to do - something that plain vanilla spreadsheets simply can't do. Even better, you can work with the Python code that Resolver One produces, or you can import your own external Python components. The more you work with Resolver One, the more you'll learn about Python.

Before you know it, you'll be using Resolver One to not only manipulate your traditional spreadsheet values of numbers, text, and dates, but also .NET types, decimals, and complex numbers. Consult third party Python and .NET component libraries, and plug them directly into your formulae to perform cunning feats of calculation that put Excel spreadsheets to shame. Craft worksheets that behave like databases. Conjure reusable spreadsheets that can be run on demand. You can even call into your spreadsheets from standalone executable Python programs!

Take your first step into a larger world. Import your existing Microsoft Excel spreadsheets into Resolver One, and start unleashing the true power of Python!

Please note: Today's promotion also includes the option to buy The Resolver One Web Server! The Resolver One Web Server allows you to turn your spreadsheets into web applications with just a few clicks. It's easy to install, and doesn't interfere with other server software running on your system. You can run it on your own machine, or install it on any Windows-based server.

Using it is simple: just specify which of the cells in your spreadsheet should be editable online, then use the built-in web server to publish the saved spreadsheet! Other people can use their web browsers to view their own copies of the sheet without needing to run it on their own machines.

Want to update the sheet? Just change it in one place and everyone gets the latest version the next time they hit the "Refresh" button. Also, you don't have to worry about users accidentally overwriting data - interactions happen in a sandboxed environment. Users can only change web-editable cells, and they can't change the original document in any way.

This promotion includes the following:

Peter Margol Regarding Mica's question more than year ago - version 2.x still not in sight? My impression is it's stuck on v1.9 almost for two years by now... Also, as promised once on your forum, will it feature the fancy new grid as well?

Giles Thomas Hi there,

1.9 was released about 9 months ago. We were intending for 2.0 to have a new grid component, but that is proving more problematic than we'd hoped. Instead, we're aiming to use that release number to add some of the features that we've been building into our new web-based Resolver One-like tool, Dirigible (, and perhaps close integration into that tool so that you can do cloud computing from Resolver One. That's not definite yet, though.

Peter Margol Hi Giles, thanks for the info. The cloud computing from Resolver One sounds very interesting - is it to keep the programs private or does it have also another advantages? Also, will it use secure protocol for the data transfer?

Giles Thomas The big advantage of the cloud-based solution is performance. You can write models as networks of spreadsheets that can execute on different cloud machines.

That's a kind of hand-wavy abstraction -- perhaps a concrete example might help. Imagine that you work at a bank and you've built a spreadsheet that needs to work out the value of some complicated financial instrument. The spreadsheet takes ten seconds to run. Now imagine that you have portfolio of a hundred of these instruments.

With Resolver One, you can create one "portfolio" spreadsheet that runs the per-instrument spreadsheet one hundred times, so you don't need to duplicate your calculations. But it still takes 100 x 10s to run -- or about 20 minutes.

With Dirigible, our cloud solution, the calculation of the 100 instruments is automatically spread over computers in the cloud (we can rent as many as our users need from Amazon), so they're all run in parallel -- so it would take just 10 seconds to calculate them all (plus a small overhead for distributing the spreadsheets out to the computers and gathering the results back).

If you want to see how this works now, before it's in Resolver One, then I recommend you take a look at Dirigible -- it's in free beta right now, and has a lot of rough edges (sadly it's pretty much impossible to make a web app as smooth as a desktop program like Resolver One), but it should clarify the point.

Regarding security -- we plan to use SSL for client-server communications both in Dirigible and in any Resolver One-based client for it.

Peter Margol That sounds all great and very useful, but people will soon require that no one (and I do mean no one) can snoop around in their precious financial or other essential data - I mean even folks at Amazon, because people are just... you know, people. It would need some kind of sofisticated Truecrypt-like (I mean open source) end-to-end encryption integration where data leaks are totally ruled out.

Giles Thomas Fair enough, I can see that that will matter to people. We'll make sure it's on the product roadmap.

Michael Begley Bitsdujour email I received says the deal price is 45% off or $54.45 but clicking the buy button says deal price is only 20% of list. What is the real deal? Thanks.

Patrick Yancey Resolver One is one COOL program! The ability to customize an application by writing Python code makes this extremely valuable.
