This gist contains everything you need to install StatsD and Graphite on CentOS 6.3.

This gist contains everything you need to install StatsD and Graphite on CentOS 6.3. Unless I forgot something. If I did, shoot a reminder email to noah at one more bug dot com. tl;dr: womm, ymmv, yolo.

I (mostly) followed the steps shown in the EZUnix wiki

And I also referred back to this gist by Michael Grace

Ruby 2.1 memory configuration

This all applies to Ruby 2.1. In some cases a setting is not available in 2.0, this is noted. There is also a different with 1.9, 1.8, and REE --- these are not noted.

All the relevant code is in https://github.com/ruby/ruby/blob/master/gc.c

RUBY_HEAP_MIN_SLOTS

default: 10000

The number of heap slots to start out with. This should be set high enough so that your app has enough or almost enough memory after loading so that it doesn't have to allocate more memory on the first request (althogh this probably isn't such a big deal for most apps).

(todo: figure out how big a slot is. i think the answer can be infered from this code.)

Eliminating Code Smell With Grunt

Eliminating Code Smell With Grunt

by Gavin Lazar Suntop @gvn

Intro

I love clean code. There, I said it. I pride myself on passing strict linting standards and keeping my code easy to read. It's not just a personal proclivity, but a choice I hope benefits other developers.

My general experience with teams has been that code style is something people care about and have strong personal preferences. Typically, at some point people get tired of dealing with inconsistency and a standardization meeting is called. This is, of course, an important discussion to have. The problem that tends to occur is either lack of documentation or lack of enforcement of the agreed upon style. Additionally, new team members or contributors may not have access to a clear set of rules.

Zig in 30 minutes

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)
