If the best way you can think of to determine the 10 most popular search queries and their click-through rates involves terabytes of intermediate data for only 10GB of input data, then you're doing something very wrong.

Give it a chance, it only has a small dataset to work with so-far.

I'm happy to answer any questions - this is based on the QuickDT library (see https://github.com/sanity/quickdt ).

Thanks, good feedback. Actually, after seeking a lot of advice I'm starting to think of the deal differently - I'll update the story so everyone can benefit.

I'm talking to a good lawyer today, they already have the LoI.

by sllrpr 15y ago
We don't really need the money, we each have other incomes that we're comfortable on. This was a speculative side-project.

by sllrpr 15y ago
No, I don't think they've signed an LoI with the other company yet.

Part of me wants to say that is a paranoid view, but I must confess that the degree to which the purchase price ramps up so quickly is a source of concern for me. $2M to $6M is a dramatic difference. It's plausible to say that they're tryi

I'm not sure how that could happen. We have the source code, if they renege on the agreement then we just go do something else with it and sue them if they continue to use it.

Fear not, a lawyer will review the deal before anything is signed.

This may sound arrogant, but I don't think they could build a clone. Our stuff is pretty sophisticated and non-obvious.

Asking for advice is not an assurance that I'll accept it uncritically. If you can't or won't back-up what you are saying then you should probably refrain from giving it in the first place. Indeed, that is my general view on advice. Advice

Yeah, I suspected it might be artificial pressure, but the pressure is only to sign an LoI, and their justification is plausible (we need to cut the other deal loose). After signing the LoI there is 45 days to complete the deal during which
