The hubris of software engineers never ceases to amaze me. I'm not trying to scare you here, I am just gently suggesting that you might not have the capacity to provide this as a public service. Keep using it for your projects if it wo

It's pretty funny that we have a post on how business rule engines are bad because users are not engineers, but also a post on how decision tables are great because users validate the program logic with their domain expertise. I think

I don't think you can use tail call recursion for tree walking unless you also manually maintain another stack. And at that point iterative code looks just as readable

I have no problem with superscripts. Here are a couple of examples of what I am talking about: \left(\Psi_{L} \circ \mathcal{A}_{l_{L}, l_{L-1}}^{\theta, \sum_{k=1}^{L-1} l_{k}\left(l_{k-1}+1\right)} \circ\right. & \Psi_{L-1} \circ

I have a strong mathematical background, and I found the notation completely insane. Right out of the gate in chapter 1 we get a definition that has subscript indices in the subscript index and a summation with subscripts in the superscript

Not every network is as simple as a router in front of a laptop. And some may treat websocket traffic differently. And do weird DNS stuff. Every time your basic assumptions are wrong, your client loses a user, and you don't even have a

The false positive rate is going to be insane. You mentioned roaming, but there are so many other scenarios where this could trigger - so, the user sits down at a starbucks and suddenly can't access the client's webpage, with some

Profitability is not the only short-term metric. In poker I know when a bet is worth it, even if it ends up not winning the pot (unprofitable). Is your argument that business people are just randomly guessing and have no idea how much profi

And yet somehow most people in charge of resourcing and budgeting for projects, teams and companies have some idea of who to hire, how much to pay them, etc. How do you think they do that with something that is nearly impossible to measure?

Big tech, yes, lots, but an extra skill required there is to recognize and actively avoid ambitious managers, who would sacrifice/burn out their own team for self-advancement. Lots of churn in big tech is purely from that. Small tech,
