In isolation because of Corona last year, I started to share many lesser-known database tricks I know on Twitter (@tobias_petry). Although I thought that only a few people would be interested in something like this, it became a matter of course over the months. Meanwhile, thousands follow me to read my database tips or news. Since every message in the constant social media stream vanishes after a few days, I had to d…

Thanks for all the valuable tips.

It's amazing every time how much load a properly configured database can reduce.

Especially the tips for optimizing indexes are very good. "Partial Indexes for Uniqueness Constraints" is my most favorite.

Would you pay money in lieu of providing your real email address? If so, how much?

I’d probably pay $10, that’s worth less to me than my contact info.

Just use a throwaway mail, what's the big deal? Companies already have tons of your private data without you ever even interacting with them. You're just crying into a 50 gallon drum of milk.

The criticism is that it's not honest. "For free" is not correct. It's "book against harvesting your contact data". If that's what the first page would say, then it would be honest and nobody would be upset. But acting as if it's been "published" out of pure altruism is just misleading people, and they are righfully pointing that out.

And what of values inherent in privacy concerns? It just seems like you're applying a very narrow view of what can be considered "value" here.

The "privacy violation" is not the value of the book, that's the cost to you. We're not discussing the values inherent in privacy concerns, we're discussing the value of the book, and whether or not you can guess at its value before you give the guy your email. You're talking about something else.

No, you're talking about something else. Obviously OOP's concern is about the value of the book vis a vis what is demanded of the recipient in exchange for the book.

Why not a series of blog posts? To me, the reader, what value does sharing my email or it being in The incredibly less flexible "ebook" format have?

You, the reader, don't have a choice between a series of blog posts and an emailed pdf.
