DVC Day 1

(This Post is part of my 30 day Data Visualization Challenge – you can follow along using the ‘challenge’ tag!)

For the first visualization, I kept it very simple:

lqB4fx5kCg-3000x3000

Pros:
– Easy to read
– Provides some value: we can see that price does not have a normal distribution, but rather a positively skewed leptokurtic distribution. I am only 70% sure I’m using these words correctly. (Thanks Professor Field!)

Cons:
– Not really very interesting
– Pretty ugly
– Does not explain what determines price, only what the prices are.

Code:

library(ggplot2)
qplot(price, data=diamonds)

30 Days of Data Visualization Challenge

Processed with VSCOcam with hb2 preset

As I work my way through Discovering Statistics Using R and discover other R-related gems across the internet, I realize that I’m only going to get better at this software if I spend time using it.

As such, I’m challenging myself to do a new visualization of a single database every day for the next 30 days – starting today, April 15, and ending May 15. The goal of this is to become more familiar with the R language, more specifically the ggplot2 library, and to think about visualizing data more generally.

The data set I’ll be using is the “Diamonds” data set package with ggplot2.

After seeing this wonderful gallery on imgur, and having had some success in the past with vegetable gardening, I said the same five words that have so often lead me down the path of adventure and triumph: “How hard could it be?” I decided to set up a little hop yard next to our back deck – for the fragrance, and for home brewing and, of course, for the experience.

After selecting a suitable piece of the property, I mapped out the size I’d need for my incoming rhizomes – I had ordered ten, from two different suppliers, so a 10′ x 5′ rectangle was the smallest I could get away with. You can see  here measuring and staking the location for each of the hop mounds. The box itself is just 1′ x 6′ boards cut to fit, with stakes in the corners. It’s roughly level. Roughly.

Following the staking came preparing the soil. wpid-20150406_164918.jpgIt turns out that at the time, the ground was frozen roughly ten inches below the surface. This made digging and preparing the bed a bit more complicated, and meant I couldn’t fertilize quite as much as I’d have liked. The real problem was that our compost was just one huge frozen cube of garbage, so these are only fertilized with organic synthetic fertilizer. I used a technique called bastard trenching, which is essentially the lazy man’s double-digging.

wpid-20150406_165705.jpgFollowing the digging and fertilizing, I laid down what felt like five or six layers of cardboard and newspaper – probably four or five months worth of old packages, coupon
booklets, etc. These will help to retain moisture in the bed, and, more importantly, retard weed growth. I’m not what you’d call an enthusiastic weeder.

wpid-20150406_180936.jpgOnce all of that is down and roughly in place, I put together what’s called a drip irrigation system – you can see the final result here – the big idea is that once it’s properly dialed in, it will run on a timer and water the bed without any intervention on my part. Yes, I sprang for the timer that can detect a rainy day and change its behavior, because who doesn’t want that?

Following the irrigation, I threw down some nice red playground mulch. This will also help to retain moisture and continue to keep things ship shape, but more importantly, it is aesthetically a lot nicer than a big wooden box of trash sitting in the back yard.

Once the mulch was down, it was time to put up the posts for the supporting lines for the hops themselves – I used three 2’x4’s along with a cut 1′ x 6′ across the top, dropping them two feet into the ground and stamping it tight. These are actually, in-fact, honestly level, since they would look insane if they weren’t.

Over the next few weeks, I need to run some steel cable between the posts, and run some clothesline from the cable down to each of the hop mounds. Until then, I’ll be keeping a close eye on the rhizomes, and hoping for the best!

Check Your Meez

Mise_en_place_for_hot_station

From Bourdain’s Kitchen Confidential:

Mise-en-place is the religion of all good line cooks. Do not fuck with a line cook’s ‘meez’ — meaning his setup, his carefully arranged supplies of sea salt, rough-cracked pepper, softened butter, cooking oil, wine, backups, and so on.

As a cook, your station, and its condition, its state of readiness, is an extension of your nervous system…

The universe is in order when your station is set up the way you like it: you know where to find everything with your eyes closed, everything you need during the course of the shift is at the ready at arm’s reach, your defenses are deployed.

Mise-en-place is not just for cooks – one thing I’ve learned working remotely for almost two years is that if my meez is thrown off, or I let it get thrown into disarray during my workday, it disrupts my flow and makes my whole day a bit more stressful. Keeping things in order, digitally, is just as important as the physical space in the kitchen.

For me, that means being vigilant about my desktop usage – I use three desktop spaces on my Mac at all times. One for communication, where Slack, Skype, and other tools like that hang out. The middle desktop is where the work happens – and only The Work. If I am digging through an analytics report, or posting on an internal blog, or talking with our customers, that’s all I’m doing. I know that if I want to check Facebook, or Slack, or whatever else, I’d have to swipe to the third desktop – and that piece of mental friction helps keep me focused.

The third desktop, that’s for Rdio and anything else that’s not communication or The Work. Twitter, feedly, that sort of thing.

I’ll admit it – sometimes I’ll open Hacker News, or Quora, or Rock Paper Shotgun in my work Desktop – and it throws me off every time. It isn’t a distraction, it’s pollution. It’s as though I’ve mixed up the tomato bin with the sliced cucumbers – it throws me off and creates a hitch in my step.

Think about your meez – take it seriously. Staying focused and staying organized can be the difference between success and stress – at least if you’re an insane person like me.
