All Jobs Tend To Face Time

June 26, 2017

I've noticed that to some extent all jobs tend to face time. Sure, there are exceptions but there is a tendency.

When you hear things like, "90% of the job is just showing up", there might be a clue there.

Large organizations seem to tend to not trust their employees and in return force a culture of face time because that is the simplest way to hold someone accountable.

"Well, at least he/she shows up" keeps many people employeed.

Showip Example In Clojure

June 24, 2017

I found a small example I wrote last year. It shows the ip address of the machine from which the program is running. It does so by calling This url returns the callers IP address in JSON.

The example shows get-ing a url and parsing the JSON.

To access the url I'm using clj-http. This returns a map from which you want the value of :body.

The JSON return value will look like this:

Python Virtualenv

June 23, 2017


Virtualenv supports the creation of isolated Python environments. This allows you to create your project with all of it's dependencies in one place.

The following is a good intro for virtualenv.

Building A Weather App In Clojure

June 22, 2017


I stumbled upon this service called Dark Sky the other day which supports an API to return weather reports. I thought it would be interesting to create a small command line application which would query this API and print out a short summary weather report. Yesterday, I took up the challenge to build such an application in Clojure.

The results are up on GitHub in the following repo.

For those who are interested I'll go through a process to build the application.
