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.

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.

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.

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

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.

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.

A few weeks ago when I was reading The Go Programming Language I was reading about buffered channels and had a gut instinct that I could write some code taking advantage of them in a precise way. This was the comical code that came out of it.

Over the past couple months I have had the somewhat uncomfortable realization that some of my assumptions about all programs are wrong. Read all about the journey involving Unix, C, Perl, and Go.

For a little over a year at ZipRecruiter we have had some tooling that “fixes” a non-trivial amount of cronspam. Read on to see what I mean and how.

Yesterday I wanted to graph some data by date but I didn’t want to mess with spreadsheet software or other graphing libraries. I reached for gnuplot after hearing good things over the years. The results were great.

I recently stumbled upon a pattern that motivates me to write little scripts in Go instead of my normal default. I was surprised at some of the benefits.

I have used Hugo, the blog engine this blog runs on top of, more and more lately for less and less typical use cases. Hopefully this post will inspire others in similar ways.

Recently at ZipRecruiter I implemented a tool to ensure that we know if some service is crashlooping. It was really easy thanks to Upstart but it took almost a whole day to get just right.

Yesterday I spent a little over an hour finally figuring out how to detect a file based on its contents in vim. It’s pretty easy!

I use Vim quite a bit and fairly heavily, so I run into a good amount of bugs. I’ll share a couple tricks I’ve learned that help debug vim.

Recently I spent time figuring out why sending items to our message queue often took absurdly long. I am really pleased with both my solutions and my methodogy, maybe you will be too.

This post is the sixth in my series about supervisors. I’ll spare you the recap since it’s getting silly at this point. This post is about readiness protocols.

This post is the fifth in my series about supervisors. The first two posts were about traditional supervisors. The third was about some more unusual options. The fourth was about the current most popular choices. This post is about some of the unusual trends I’ve noticed during my three year long obsession with supervisors.
Posted Wed, Jul 26, 2017
This is the latest in my apparently unending series about supervisors. While the first two posts were about “traditional supervisors,” the third was about a few odd variants, both good and bad. This post is about the current reigning champions: Upstart and systemd.

This post is a continuation of my series about suprevisors. The first post was about the most basic supervisors. The second post was about some more advanced, but still basically traditional supervisors. This post is about some more unusual options.

At my talk at YAPC a few weeks ago I discussed some technology at ZipRecruiter that’s called the read/write splitter (or more often the rwsplitter or simply the splitter.) I have intended to write about this for a long time and the fact that I was unable to refer to a blog post for the talk finally convinced me that I must.

A year ago, when I was on paternity leave, I decided that I needed to be better at time management. I think that my inspiration was simply the recommendation of the book, Getting Things Done by Alfie John. Having used the GTD system for about a year, I feel comfortable writing about it.

A couple of weeks ago I went to YAPC::NA 2017. I already wrote about my own talk, but I still want to highlight a few other talks that I think people should see.

I did a talk at YAPC this year, and while I am really proud of it and think that it went well, I think it could have gone better. This post is a retrospective on what I could do better next time.

On Monday I wrote about using Amazon Athena from Perl. That’s only step one though, because often I find myself needing to dig further.
Posted Wed, Jun 14, 2017
At ZipRecruiter we write “a lot” of logs, so actually looking at the logs can be a lot of work. Amazon Athena provides a nice solution, and recently an API was (finally) provided to allow us to use it in our code. I wrote some code recently to leverage the API.
Posted Mon, Jun 12, 2017
On Monday I wrote about how QuickFix and friends are slow. I was legitimately chasitized on reddit for giving up too soon in trying to find a solution, so I did some more digging.

Last time I blogged about vim sessions I showed a cool pattern for making sessions more generally useful. There was a bug in my example that hamstrung the technique, so I’ll be sharing and updated version here.

I have recently been working on honing a lot of my tools, and a coworker, Andrew Ruder, mentioned using Denite.nvim for selecting more than simple directories. I decided to investigate using it instead of builtin file selection mechanisms. I was surprised at the result.
Note: while this post is still worth looking at for comparing how you can define various lists for vim, the performance issues turned out to be unrelated. See my new post for more details.

At ZipRecruiter we use AWS for nearly all of our infrastructure, so securing our usage of AWS is important for obvious reasons. In this article I will go over some of the things that I had to do (with help) to go from “pretty insecure” to “pretty secure” with respect to AWS permissions.

Sometimes I will edit a huge file and got confused or distracted and lose track of where in the file I am. I wrote a tool a few days ago and integrated it into vim. It’s pretty cool.

I have a ton of little programs I use on a day-to-day basis just to make my life easier. I figured it would be fun to share them so other people could either copy them or be inspired to make there own. I have blogged about some of these tools before and will link to the appropriate full posts when applicable.
