"Home" is a dumping ground for random notes that don't really fit anywhere else (To Read, To Investigate, Groceries).

"Financials" has receipts and other tax related info I need to keep track of.

"carpeaqua" is for any in-progress posts for this site. I have a different page for each post idea and its content.

"Lawn + Garden" is another section in my Personal notebook. I've become a bit obsessed recently with fixing the lawn and beddings …

But so many pages. Could I justify another pop-sci book on my To Read stack? Could I justify the time? Would it be fluff? or a difficult slog? If I'm reading for fun, I don't want it to be harder work than what I already do for, you know, work.

Wasted worry.

The Information is a layman's introduction to Claude Shannon's information theory. It covers a lot of ground, and while it can be a bit slow in parts, it's enjoyable. As a programmer, I was aware of …

…able to achieve that, but how much they love us because of that — they really love what we have done. It's a great surprise, to every now and then be hugged by somebody at a conference — they know you, but you don't know them. It's really nice.

…you can use to_a to get the array of data on it. This is a convenience method for # read and # readlines .

This is the concrete use case behind why …

How To Read A SaaS Pricing Grid (And Why You Should Charge More)

I thought I'd read a pricing grid. This one's from Wufoo. You have seen similar things all over the Internets. I can't tell you about exact results I've gotten from customers, but I talk to a lot of people about this sort of things, so if we're just kind of anonymizing, here's how you read it. Find the largest dollar‑amount plan. That plan generates 33 percent to 50 percent of gross revenue. …

Based on a lot of surprising comments about my MySQL 5.5 vs 5.6 performance post I decided to perform deeper investigation to see where my results could go possibly wrong. I had set up everything to be as simple as possible to get maximally repeatable results. I did Read Only ran which is typically a lot more repeatable (though also less relevant for production like workload). I had done number of iterations for benchmark run and I used dedicated physical hardware box so external …
