I’ve got a hankering for keyboard shortcuts.

I’m all about pressing a key without having to worry about which application I’m in and my computer doing something useful.

This noble pursuit has taught me one thing: there’s never enough keys™.

Good old Vim has demonstrated the value of a trusty leader key in the war to get more keys. So, I undertook a holy mission to find the mythical macOS hyper key, and along the way found the deep well of keyboard customisation that is Karabiner-Elements.

Hyper key

I’ve set up Karabiner-Elements so that if I combine the backslash key with other keys, it acts as the hyper key ¹.

I use this hyper key as a prefix to bind global shortcuts without having to crush my fingers, and soul, into a ball.

Here’s a selection of the shortcuts I keep behind this hyper key prefix:

• \+t brings my time tracking app into focus.
• \+s locks my screen.
• A bunch of shortcuts move windows around via Moom.
• A couple of shortcuts switch my audio output between my headphones and speakers via an Alfred workflow.

Mouse buttons

macOS doesn’t natively recognise the extra buttons on my new mouse which sucks because: there’s never enough keys™.

So, I was chuffed to find that Karabiner recognises these extra mouse buttons and can bind them to key sequences.

Here’s a look at my bindings:

I miss the sideways scrolling of the Magic Mouse, but I’ve set up Karabiner so that if I hold down my scroll wheel button, I can scroll left and right. It works reasonably well and means I don’t need to reach for shift while spinning the scroll wheel to side-scroll.

I map button 4 of my mouse to play and pause my music. The media keys on my keyboard are a chord away, but usually, it’s easier to press a single button instead.

I map button 5 to a shortcut² assigned to the Meet Mute Chrome extension. This shortcut toggles mute on my current running Google Meet meeting, which is killer.

The config

So there you go. Maybe you’ll find something useful in my Karabiner-Elements config file that you can steal.

And may you never run out of keys.

I rebuilt A Strange Kind of Madness using Hugo a month or so ago. As with most photoblogs, it has pages with many images on them, and I was inspired by Photo Stream to load these images lazily.

Image resizing

If you want Hugo to resize images when it builds a site, you need to place your images alongside posts, so they are considered page resources. So, I put each post in a folder with its associated image and reference it in a field called, shockingly, image in the post front matter.

$ ls content/posts/2020-03-31-my-post
20200331-4491.jpg
index.md

$ cat content/posts/2020-03-31-my-post/index.md

title = My Post
date = 2020-03-31T10:42:00+08:00
image = 20200331-4491.jpg

Adding Lazyload

Roll-up pages have many thumbnails and benefit most from lazy loading.

First up, add the lazyload javascript library to your site build.

import Lazyload from "lazyload";

// Fire up our lazyloading (just initialising it does the job)
const _lazyload = new Lazyload();

The library’s default configuration targets images with the lazyload class and loads the image stored in the data-src attribute. If you place an image on the standard src attribute, it will be treated as a placeholder.

Placeholder images

I wanted something more interesting than a sea of grey rectangles for placeholder images. I had a look at using BlurHash, but that was going to involve rendering canvas elements for placeholders ¹.

I want the front end to be as simple as possible ², so I abandoned that approach and instead created a single-pixel resize of the source image which provides a simplistic average colour placeholder for each image. It does the trick.

The markup

All of the necessary resizing code and markup is in a Hugo partial that renders a thumbnail for each post. Be sure that your image tags include width and height attributes so the browser lays them out correctly such that lazy loading is effective.

{{- with .Resources.GetMatch (.Params.image) -}}
  {{/* Resize to a single pixel for a placeholder image  */}}
  {{- $placeholder := .Resize "1x1" -}}
  {{/* Resize to 800 pixels wide for a thumbnail image */}}
  {{- $thumbnail := .Resize "800x" -}}
  <img
    src="{{ $placeholder.RelPermalink }}"
    data-src="{{ $thumbnail.RelPermalink }}"
    width="{{ $thumbnail.Width }}"
    height="{{ $thumbnail.Height }}"
    class="lazyload" />
{{- end -}}

The main downside to this is that two resizes for each image adds a bunch of time to the site’s build process but that’s a trade off I’m willing to make.

Go forth, and embrace laziness.

I’ve been working from home full time for four years, and my desk setup has mostly remained the same during that time. But the recent spate of folks sharing their home office setups—this Basecamp post was my favourite—inspired me to spruce up my own.

So, now it’s tour time folks!

My work laptop (1) is a 13 inch 2017 MacBook Pro. It’s got the busted keyboard design. I mostly use an external keyboard, so mine still works fine 🤞.

My monitor (2) is a 27 inch Dell that’s six years old. It does the job. I’ll probably wait until it dies before I replace it.

I use a Kinesis Advantage 2 keyboard (3) which lets me hold my hands like a T-Rex while I type. It’s easy on the wrists but beware, it took me six months to type on this thing properly, and those six months were tough going so perhaps not a fun challenge to take up during already potentially stressful quarantine times.

I replaced my trusty stack of too-dry-to-read textbooks with the brutalist styles of this monitor stand by Brateck (4). It has a drawer where I can store my notebook and pens when I’m not using them. But what tickles the organiser in me the most is the cavity beneath it where I can store other things¹.

Pictures and plants are, of course, essential (5 & 6).

I used an Apple Magic Mouse for years, but it started acting flaky after I upgraded to Catalina. So, I switched to a Razer Death Adder (7) which is way more comfortable to hold. It doesn’t allow me to side scroll as easily but not recharging batteries regularly is nice. Also, it has disco lights and a USB cable. Actually, let’s talk about cables and wires for a minute.

So, wires. Yeah, they get in the way. Yeah, they can look ugly. But you know what else they are? Reliable. That’s right, like a blue heeler at dusk, they’re always there for you. They mean there’s no more stuttering when you move your mouse. You don’t need to worry about Wi-Fi turbulence when you’ve got an old fashioned Cat 6 cable plugged in baby ². With that off my chest, let’s get back to the tour.

Next up is the linchpin, the box that brings it all together. A couple of my colleagues recommended the CalDigit TS3 Plus Thunderbolt dock (9) and it’s tops. I plug everything into it, USB devices, my router, my display, my microphone and headset—and it all flows to my laptop via a single Thunderbolt cable (8). The TS3 Plus also serves as a power source for my MacBook so I can leave my power cord in my bag for that wondrous time, someday in the future when I can work outside again.

I spend a large portion of my day on video calls so a reliable audio setup is essential. I have a Jabra headset which is light and comfortable, but I also have an old set of Sennheisers (10) that I enjoy listening to music through. Again, some colleagues tipped me off to the fact that I can frankenstein a microphone onto any headset by using an Antlion ModMic. Its hardware mute button isn’t as low down on the cord as I like, but at least it’s there.

Another bonus of wearing this new set up is that I look like a helicopter pilot instead of a call centre worker and who doesn’t want to look like a helicopter pilot, right?

I run my headphones into a Magni 2U headphone amp (11) and plug that and the microphone directly into the TS3 Plus ³. So now, I have my favourite headphones handy when I need to concentrate and want to listen to something from one of my go to playlists (or White Noise).

When I want to listen to music without headphones, I stream it through my fairly ancient Jambox (12). It’s rugged and still trucking though I expect the battery to self combust any day now. I've ordered a pair of Audioengine HD3 speakers to replace it because my ears deserve it.

Update: There weren’t any HD3’s in stock so I instead went with a pair of Edifier R1280DB’s. They are cheaper, connect to the TS3 via digital optical cable, sound good, and look alright.

I’ve also ordered a Logitech C925E webcam which I’ll mount on my monitor so I’m not always side-eyeing folks from my laptop camera in meetings.

I spent a scandalous amount of money on a Herman Miller Embody (13) when I first set up my home office. I never worry about my chair, so I think I can say that money was worth it 🤷‍♂️.

Finally, there’s my desk (14). It is a standing desk that I put together eight years ago. Back then, it was tricky to find standing desks online, so to save money, I only ordered legs from GeekDesk ⁴ and attached a bamboo tabletop from Ikea to them. The top could be a bit larger, but maybe I’m just greedy.

So, there it is—the throne of my weekday castle.

There are a window and couch out of shot to the left. The couch is mostly ornamental because if I allow myself to lie down on it and close my eyes for just one minute, all will be lost.

I still like listening to albums and sometimes want Spotify to play a random album from a playlist of albums I’ve created.

I couldn’t find anything out there that does this so I wrote myself a script to handle it instead.

Here’s a rundown if you want to use it.

First up, you’ll need a playlist with at least one track from each of the albums you want to choose from (here’s mine). Grab the ID of your playlist¹, and your username and add them into the script below.

Then, you’ll need to create an app in Spotify and get your client ID and secret, add them to the script below, so you can authorise the script.

Finally, run gem install rspotify in your default ruby² and you should be off to the races.

Run the script with Spotify desktop app installed and it’ll open up a random album for you to press that sweet, sweet play button on ⏯.

I run the script from an Alfred workflow so I’ve got it close at hand.

Enjoy 🎷🎶

I read the majority of my books on my Kindle. The Kindle’s convenience is pretty hard to beat and I enjoy its highlighting and note-taking features.

With that said, I find I miss the context that a physical book provides. It’s much easier to breezily flick around a physical book to find previous sections you’ve read or peek ahead to see what’s coming up.

Recently I fired up the Kindle for Mac and found that I can get better context and a view of my highlights all at once. Open it up in widescreen, open the contents and notes and highlights sidebars, and boom baby, you can see a summary of where you are in the table of contents and what passages you’ve highlighted or bookmarked on the right.

I find this arrangement particularly helpful when reviewing a book I’ve previously read. Have a crack yourself, see if you like it.
