Configuring iTerm For a Better Keyboard Experience

The default terminal on OS X isn’t really that great. It doesn’t let me reconfigure keybindings to my liking. There are two other terminal choices for OS X: Hyper and iTerm 2. When it comes to being customizable, I think Hyper wins. However, there are some really annoying things about it: It is an Electron app, which means it is a memory hog. You cannot drag and manipulate tabs the way you can with native apps.

Interview Questions

Good technical interview questions are hard to find. In the last month, I’ve seen some really great ones and equally bad ones. I want to go through some of them and write down my highly biased 5-star rating on their effectiveness. First, for some context on how I evaluate interview questions. Your interview questions should be: Respectful of the candidates Objective and evaluated consistently Gathers relevant and insightful data

Deploying Go

I’ve written a lot of Python. If I need to create something quickly, I tend to go to Python. I’ve written a lot of Java. But I almost never write Java code outside of work. One thing I liked about Java over Python, however, was ease of deployment. I can package all third party dependencies into a single executable jar, making it easy to upload and distribute artifacts. I have never mastered packaging Python for distribution.

Own Your Data

I previously wrote about owning my own data. An important part of data ownership is backing up your data. I use S3 as my long term data store. It is pretty easy to set this up using Terraform.

S3

Provisioning a S3 bucket is simply a single Terraform resource:

resource "aws_s3_bucket" "repo_archive_log" {
  acl = "log-delivery-write"
  bucket = "example-bucket"
  tags = {
    Name = "example"
    TTL = "persistent"
    ManagedBy = "Terraform"
  }
}

Stupid Emacs trick for writing Go code

Lately, I have been writing more code outside of full-fleged IDEs and found myself tweaking Emacs into a lightweight IDE for Go. Having gofmt automagically formatting the code and refreshing it in the buffer is simply lovely. My current go-mode cusomization looks like this:

First, get the excellent go-playground package.

(package-install 'go-playround)

Then, configure Emacs

;; Automatically format your code on save
(add-hook 'before-save-hook 'gofmt-before-save)

;; Automatically display gofmt processed code in buffers
(custom-set-variables
 '(global-auto-revert-mode t)
 '(auto-revert-interval 1))

;; Verbose output when running tests via go-test-current-*
(setq go-test-args "-v")

Another year, another blog

A little more than a year ago, I moved my blog from Blogger to Medium. Medium, as a blogging platform, was always meant to be temporary. It is platform with a modern look. It is a free service. One does not need to worry about domain registration, uptime, security patches(!), or a host of little things that adds up. The price is, however, to give up control of your content.
