Boolean alias

glog.V is neat-o

glog implements log levels with a nice boolean alias. Starting at line #983, the Verbose, when wrapping the boolean true causes its various functions to invoke the logger. So if you pass in -v 3 on the command line and use glog.V(2).Info("hello") in code, your logger will write the message. This allows glog to have far fewer log . . .

One cool thing about testing in go

*_test.go files aren't compiled or lexed until you run go test. You change them without breaking your non-test code compiles. They stay out of the way until they are needed, which is a nice trick.

Intel Build for Gaming 2017Q1

i7-7700k 4.2GHz, z270, DDR4 2400, M.2 PCI 3.0 x4; yes please.

(output is raw output from PCPP, Adjusted prices and vendors . . .

Decomposition

When I come up against a problem of any non-trivial nature, I spend a lot of time on the decomposition of that problem into smaller problems. One such example is the work I'm doing with my team's API gateway.

We have a 4-tier system:

  1. CMS (Database to XML)
  2. API gateway (multiple protocols to protobuf)
  3. . . .

Layers

Don't mix business logic with service logic

Go kit has a pretty opinionated view about how a Go-based micro-service should work:

  1. You start with core business logic
  2. Then wrap it in flexible layers adding
  3. Handlers
  4. Endpoints
  5. Transports

Though it seems tedious at first, I found myself feeling a certain clarity while working on a small experiment . . .

My Languages

Herein I list my current programming languages.

Go

I use go the most and enjoy it the most. It provides a few features I haven't used elsewhere with as much success, such as compositional inheritance, automatic interfaces, and useful concurrency primitives. While I admittedly don't use the last one as often, when I . . .
