Code Search for Go

For a long time I’ve been disappointed by github’s code search functionality and the disappearance of other tools that used to do the same thing. This weekend I came up with a scrappy solution that meets my needs.

go/types package

This past weekend I spent some time playing with the go/types package. It was pretty cool!

AwesomeWM II

I just switched back to AwesomeWM. I used AwesomeWM from 2012 to 2017, so this almost feels like a relief.

Stupid Default Alerts for cronjobs

Today I whipped up an initial default set of cronjobs for all of our teams at ZipRecruiter. It was almost trivial and will get most teams started on at least not-terrible alerting. Neat.

Deploying to AWS Lambda with ZR CI/CD

On Friday I got started on a very basic set of tools to deploy code to lambda easily.

Leatherman: Using `go generate`

This weekend I updated the leatherman’s code to be a little more automated, using go generate and some nice parsing tooling.

The Go Errors Proposal

Last week I sorta dove into the proposed interfaces for errors that will probably come out with Go 1.13. This is my experience.

The Easiest Way to Use Go from Source

Recently I saw someone suggest using the unreleased version of Go, without the magically easy way to do it. Here’s how.

Prometheus cloudwatch-exporter Examples

Today I spent a few hours figuring out how to integrate Prometheus with AWS.

Lag from Timers in Go

I noticed that timers in Go aren’t perfect.

Prometheus Conveniences

At ZipRecruiter we are working towards migrating to a Prometheus as a more modern monitoring solution. I have found it pretty pleasant, so far.

Learning Day: Recovery

This weekend I did one of my learning days but instead of my preferred aggressive pace I took it a little easier.

Optimizing my Workflow for Go

I spent about four hours programming on a plane last week; thanks to good tools it was fun and easy.

Testing in Go

This weekend I wrote a bunch of “happy path” tests in Go.

Reading Code

I enjoy reading code and want to talk about it.

Sorting Books

I wrote a little program to sort lists of books.

Automating Email

I just automated a couple common email tasks.

How to Add a Subscription Service to Your Blog

I used to use a service to email subscribers updates to my blog. The service broke, but I automated my way around it.

Fixing Buggy Haskell Programs with Go

I recently ran into a stupid bug in a program written in Haskell and found it much easier to paper over with a few lines of Go than to properly fix.

Learning Day 2: DIY Games

Today I did my second Learning Day; the subject was DIY Games.

Busting the Cloudflare Cache

I automated blowing the cache for this blog. Read on to see how I did it.

graphviz describing multi-stage docker builds

I recently decided I should learn to use Graphviz more, as a great tool for making certain kinds of plots. Less than a week later a great use case surfaced.

Amygdala

This past weekend I started re-creating a tool I used to have, using new tools, techniques, and infrastructure. The tool allows, at least, adding to my own todo list via SMS. It’s working great!

Deploying to Kubernetes at ZipRecruiter

At ZR we are working hard to get stuff migrated to Kubernetes, and a big part of that is our cicd pipeline. We have that stable enough that I can explain the major parts.

Full Text Search for ebooks

This past weekend I did a learning day that inspired me to try SQLite for indexing my ebooks; it worked!

Learning Day 1: go

This is the first Learning Day Log I’m publishing, and it’s about Go.

Go Interfaces

I did some work recently that depended on Go interfaces and I found it both straightforward and elegant.

The Evolution of The Minotaur

I have a tool called The Minotaur that I just rewrote for the third time, and I think, maybe, it’s done.

Self-Control on a Phone

Today I discovered that a lot of people feel alone in how they feel chained, in one way or another, to their phones. I started the fight against that recently and thought my findings might help other people.

Updates to my Notes Linking Tools

I recently improved some of my notes tools, most especially around linking to emails.

Goals for 2019

As many do, I am attempting to affect 2019 by picking skills to improve, subjects to learn, ways I hope to improve as a person, and then deriving (hopefully) concrete milestones to benchmark that progress.

Self-Signed and Pinned Certificates in Go

I recently needed to generate some TLS certificates in Go and trust them. Here’s how I did it.

Validating Kubernetes Manifests

At ZipRecruiter my team is hard at work making Kubernetes our production platform. This is an incredible effort and I can only take the credit for very small parts of it. The issue that I was tasked with most recently was to verify and transform Kubernetes manifests; this post demonstrates how to do that reliably.

go generate: barely a framework

I’ve been leaning on go generate at work a lot lately and, when discussing it with friends, found that they had trouble understanding it. I figured I’d show some examples to help.

Go Doesn't Have Generics

Go doesn’t have generics. This isn’t news, but it’s more foundational than many might realize.

Go Concurrency Patterns

I’ve been spending some time the past couple of weeks playing with some of my personal Go tools. Nearly everything I did involved concurrency, for a change. I’ll document how I did it and some of the wisdom I’ve gathered from others here.

Atomically Directory Population in Go

At work I’m building a little tool to write data from AWS Secrets Manager to a directory on disk. I wrote a little package to write the secrets atomically, because that seemed safest at the time. In retrospect just writing each file atomically probably would have been good enough. Code and discussion are below.

GopherCon 2018

This year I went to GopherCon. This post is a grab bag of what I thought was interesting and some thoughts on this conference vs others and conferences in general.

Log Loss Detection

We spent hours debugging a logging issue Friday and Monday. If you use UUIDs in Perl, you should read this post.

Some Cool New Tools

I’ve written (and ported) some new tools and thought others might find them useful or inspiring.

unproductive

I’ve always wanted to carefully measure my activity on the computer and recently built a tool called unproductive to make it happen.

Announcing shellquote

In my effort to port certain tools to go I’ve authored another package: github.com/frioux/shellquote.

Detecting who used the EC2 metadata server with BCC

Recently at work we had a minor incident involving exhaustion of the EC2 metadata server on some of our hosts. I was able to get enough detail to delegate the rest to a team to fix the issue.

Centralized known_hosts for ssh

I just wrote some code to make a (hopefully) trustworthy, shared known_hosts file for our whole company. A handy side benefit is that it also grant us hostname tab completion.
