thebigjc··on The Tesla Semi from an Insider's View After One Year: "Hot Mess"
This is happening in Canada. It's a huge boogie man from the opposition, even if it's revenue neutral.

thebigjc··on AWS mistakes to avoid
This is super important - I've run a number of 'oversized' instances just to get better networking. AFAIK none of the cloud providers offer a way to create a 'network' optimized instance, though containerized deployments should help with under utilizing the rest of the instance.
thebigjc··on Recommending items to more than a billion people
Lots of research here, but the most interesting part is their distributed graph approach. Scaling up CF is a challenging problem, and the current open source implementations have problems at really large scales.

I hope they open source their Giraph implementation, or at least part of it.

Housing is getting expensive, but most Cost of Living indexes put NYC/SF 30%+ higher than Toronto proper, and areas around Toronto are still somewhat affordable.
thebigjc··on FoundationDB: A new generation of NoSQL database
Snapshops / backups with MVCC isn't that complicated - you take a snapshot of the versions, and then backup the data at that version.
thebigjc··on Ask HN: What's your churn rate?
Is there an equivalent or similar metric for non-subscription commerce sites? I operate one, and I'm struggling to find good references on the best way to determine I've 'lost' a customer.
thebigjc··on Ask HN: Opportunity to earn a cut on every transaction. How big should my cut be?
There's two ways to do it:

1) Go simple - affiliate fees in ecommerce range from 4-8%. Pick a number you're comfortable with and use that.

2) Do the math - estimate their revenue per year/month/week, do a Net Present Value calculation, using a discount rate based on the fact you're getting paid over time, and the fact that you may never get paid. Divide your quote for option A by the NPV, and that's your % to ask for.

thebigjc··on Ask HN: Opportunity to earn a cut on every transaction. How big should my cut be?
It should be a % of their gross, not their net. Don't make the mistake of letting their profit margin determine how much you get paid.
