here's a side project I've been working on for a few mornings: programmingpuzzles.com
it's a list of programming puzzles i've come up with; they are designed not to be *too* hard (they should take 20-30 minutes to finish), so you can knock one out before you head off to work

Are you cracked enough to solve these programming puzzles? 7 puzzles and counting!

Can we replace SQL with functional programming? We take it as a given that relational languages are used to query databases, but there’s no reason we couldn’t use a language based on the lambda calculus!

it’s interesting that you could basically emulate type classes with explicit dictionary passing and row typing. i guess you could also implement monad transformers like this?

You’re absolutely right — you are Pagliacci. It would certainly be difficult for you to attend your own performance! I should not have given such paradoxical advice, and I apologize deeply for the error. There is no excuse for my failure.

what are people using for email automation nowadays? i basically just want to send emails to a list, with good deliverability; i don’t really care about any marketing features or transactional email. too broke for mailchimp.

Yesterday we hosted the very first edition of Func Prog Conf, and I'm very happy about how everything turned out! The speakers all delivered stellar performances and the mood was great. I hope everyone enjoyed the "hallway track" as much as I did!

a lot of communist theory is flawed because it rests on the assumption that wealth is a common good that just exists, and that "capitalists" are simply rent-seekers who extract value from it. however, in the digital world, this is much closer to the truth
