      <description>&lt;p&gt;It has been on my bucket list for awhile now to expore &lt;a href=&#34;https://jupyter.org&#34;&gt;Jupyter Notebooks&lt;/a&gt; as a solution for data analysis and computational story telling needs. I finally took the time to sit down and understand the tooling and authoring experience and figured I would document the process and share it.&lt;/p&gt;
&lt;h3 id=&#34;installation-process&#34;&gt;Installation process&lt;/h3&gt;
&lt;p&gt;My local development environment is a MacBook Pro running Catalina. I started out by installing and launching the Jupyter Notebook server using &lt;a href=&#34;https://www.anaconda.com/products/distribution&#34;&gt;Anaconda&lt;/a&gt; which was uber simple.  I did want to be able to reproduce the installation and execution steps in a containerized pipeline so I ended up just doing a python package install after a bit of research on core python packages necessary.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-bash&#34; data-lang=&#34;bash&#34;&gt;$ pip install notebook pandas matplotlib
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;&lt;strong&gt;Note:&lt;/strong&gt; For a pipeline of course I would pin the package versions in a &lt;code&gt;requirements.txt&lt;/code&gt; file to ensure I had reproducible builds.&lt;/p&gt;
&lt;h3 id=&#34;trying-it-out&#34;&gt;Trying it out&lt;/h3&gt;
&lt;p&gt;Now that I have the Jupyter CLI installed I can start the Jupyter notebook server which opens a browser to localhost:8088 with a simple file explorer and a few options including creating a new notebook.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-bash&#34; data-lang=&#34;bash&#34;&gt;$ jupyter notebook
&lt;span style=&#34;color:#f92672&#34;&gt;[&lt;/span&gt;I NotebookApp&lt;span style=&#34;color:#f92672&#34;&gt;]&lt;/span&gt; Serving notebooks from local directory: /Users/a_user/Documents
&lt;span style=&#34;color:#f92672&#34;&gt;[&lt;/span&gt;I NotebookApp&lt;span style=&#34;color:#f92672&#34;&gt;]&lt;/span&gt; Jupyter Notebook 6.4.10 is running at:
&lt;span style=&#34;color:#f92672&#34;&gt;[&lt;/span&gt;I NotebookApp&lt;span style=&#34;color:#f92672&#34;&gt;]&lt;/span&gt; http://localhost:8888/?token&lt;span style=&#34;color:#f92672&#34;&gt;=&lt;/span&gt;a_token
&lt;span style=&#34;color:#f92672&#34;&gt;[&lt;/span&gt;I NotebookApp&lt;span style=&#34;color:#f92672&#34;&gt;]&lt;/span&gt;  or http://127.0.0.1:8888/?token&lt;span style=&#34;color:#f92672&#34;&gt;=&lt;/span&gt;a_token
&lt;span style=&#34;color:#f92672&#34;&gt;[&lt;/span&gt;I NotebookApp&lt;span style=&#34;color:#f92672&#34;&gt;]&lt;/span&gt; Use Control-C to stop this server and shut down all kernels &lt;span style=&#34;color:#f92672&#34;&gt;(&lt;/span&gt;twice to skip confirmation&lt;span style=&#34;color:#f92672&#34;&gt;)&lt;/span&gt;.
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;I selected the option to create a notebook and found myself staring at an empty Jupyter Notebook.&lt;/p&gt;
&lt;p&gt;&lt;img src=&#34;https://jamessevedge.com/jupyter-notebook-new.png&#34; alt=&#34;Jupyter Notebook New&#34;&gt;&lt;/p&gt;
&lt;h3 id=&#34;finding-some-data&#34;&gt;Finding some data&lt;/h3&gt;
&lt;p&gt;To create a useful Jupyter notebook I needed a simple data set so I downloaded a CSV file containing daily trading data on the S&amp;amp;P 500 for the 20 years starting from 2000.  Here is what a sample of that data looks like.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-bash&#34; data-lang=&#34;bash&#34;&gt;$ wc -l data.csv
    &lt;span style=&#34;color:#ae81ff&#34;&gt;5000&lt;/span&gt; data.csv
$ tail data.csv
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 14, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,465.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,449.70&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,473.00&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,449.70&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1.07%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 13, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,449.70&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,432.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,454.60&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,432.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1.22%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 12, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,432.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,439.10&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,445.30&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,427.30&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-0.44%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 11, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,438.60&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,457.60&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,458.80&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,434.40&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-1.30%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 10, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,457.60&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,441.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,464.40&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,441.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1.12%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 07, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,441.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,403.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,441.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,400.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;2.71%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 06, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,403.50&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,402.10&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,411.90&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,392.00&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;0.10%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 05, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,402.10&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,399.40&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,413.30&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,377.70&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;0.19%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 04, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,399.40&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,455.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,455.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,397.40&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-3.83%&amp;#34;&lt;/span&gt;
&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;Jan 03, 2000&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,455.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,469.20&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,478.00&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;1,438.40&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-&amp;#34;&lt;/span&gt;,&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;-0.95%&amp;#34;&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;Now of course I could import this data set into Excel, Tableau, etc. to perform data visualization but the point of this exercise was to evaluate Jupyter notebooks which allow for not only data visualization but also data preparation (&lt;a href=&#34;https://pandas.pydata.org&#34;&gt;pandas&lt;/a&gt;), machine learning (&lt;a href=&#34;https://scikit-learn.org/stable/&#34;&gt;scikit-learn&lt;/a&gt;), etc.  In general it has greater flexibility in functionality as the design allows for computational storytelling given the free form ability to add rows of markdown mixed in with the computational rows.&lt;/p&gt;
&lt;h3 id=&#34;creating-the-notebook&#34;&gt;Creating the notebook&lt;/h3&gt;
&lt;p&gt;Most of the learning curve came while trying to undertand how to do data preparation and visualization with &lt;a href=&#34;https://pandas.pydata.org&#34;&gt;pandas&lt;/a&gt;.  To do that I looked at the documentation on their &lt;a href=&#34;https://pandas.pydata.org/docs/&#34;&gt;site&lt;/a&gt; until I got a basic understanding of the steps necessary to view, clean and visualize a data frame. A neat thing about Jupyter notebooks is you can run each step independently of the rest so if some steps take a long time to complete you can run those once and iterate on subsequent steps.&lt;/p&gt;
&lt;h3 id=&#34;exporting-the-notebook&#34;&gt;Exporting the notebook&lt;/h3&gt;
&lt;p&gt;Once I had a working notebook I wanted to export it so I could share it with other people easily.  The Jupyter CLI has a command called &lt;code&gt;jupyter nbconvert&lt;/code&gt; with support for a variety of output formats including popular options such as RST, HTML and PDF.  Getting an HTML file is perfect as I can embed that as an iframe and share it right here in this article.  I wrote a script to automate generating HTML from a folder of 1+ notebooks, if you take out the for loops and boilerplate this is the command I ended up running to turn the &lt;code&gt;.ipynb&lt;/code&gt; notebook file into &lt;code&gt;.html&lt;/code&gt;.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-bash&#34; data-lang=&#34;bash&#34;&gt;$ jupyter nbconvert --execute --to html notebooks/stock-analysis/notebook.ipynb --stdout &amp;gt; static/notebook-stock-analysis.html
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;h3 id=&#34;viewing-the-notebook&#34;&gt;Viewing the notebook&lt;/h3&gt;
&lt;iframe src=&#34;https://jamessevedge.com/notebook-stock-analysis.html&#34; style=&#34;height:100vh;width:100%;border:none;overflow:auto&#34;&gt;&lt;/iframe&gt;
&lt;p&gt;Looks like stocks have been doing OK.  Definitely no need for any sort of disclaimer that &lt;em&gt;past performance does not predict future results&lt;/em&gt; right?&lt;/p&gt;
&lt;h3 id=&#34;recap&#34;&gt;Recap&lt;/h3&gt;
&lt;p&gt;Authoring a Jupyter notebook from scratch and understanding the core data analysis libraries did not end up being a massive learning curve so the experience was great overall.  I may use it more in the future for scenarios where Tableau is too heavy handed a solution or perhaps to glean insights using unsupervised machine learning given the right data set.  I would like to explore the JupyterLab, JupyterHub and other projects that enable authoring and publishing like Voila.&lt;/p&gt;

      <title>Creating a Custom Tesla Light Show</title>
      <link>https://jamessevedge.com/articles/custom-tesla-light-show/</link>
      <pubDate>Tue, 22 Feb 2022 00:00:00 +0000</pubDate>
      <author>jjesc1031@gmail.com (James Sevedge)</author>
      <guid>https://jamessevedge.com/articles/custom-tesla-light-show/</guid>
      <description>&lt;p&gt;In late December Tesla pushed out a new major update to my Model Y dubbed &lt;a href=&#34;https://www.tesla.com/blog/introducing-software-v11-0&#34;&gt;&amp;ldquo;version 11.0&amp;rdquo;&lt;/a&gt; which included a revamped UI and a bunch of new features.  Probably the coolest feature released was the Light Show which allows creators to use a sequence show tool called xLights to turn on/off or ramp various lights, open/close the windows, open/close the trunk, etc.  The Tesla also included a default light show which at the time was holiday themed and got a good reaction from friends/family, pretty sweet to get OTA updates on a car right?  Anyways I finally got around to building a custom light show and figured I would take notes as I went and write about it in case others find it interesting and would like to do the same.&lt;/p&gt;
&lt;h3 id=&#34;documentation&#34;&gt;Documentation&lt;/h3&gt;
&lt;p&gt;The Tesla engineering team put together a great readme and linting tool which they published under the &lt;code&gt;teslamotors&lt;/code&gt; Github organization &lt;a href=&#34;https://github.com/teslamotors/light-show&#34;&gt;here&lt;/a&gt;.  It covered most of the details I needed as long as I was willing to jump around a bit as I progressed.&lt;/p&gt;
&lt;h3 id=&#34;installed-software&#34;&gt;Installed software&lt;/h3&gt;
&lt;p&gt;Once I read through the documentation I went ahead and installed the xLights application using the Apple app store on my Mac.  &lt;strong&gt;Note&lt;/strong&gt; that xLights supports all the major OS platforms, see the &lt;a href=&#34;https://xlights.org/releases/&#34;&gt;download page&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;I then downloaded the sequenece model the Tesla engineering team created and provided a link to in this &lt;a href=&#34;https://github.com/teslamotors/light-show#getting-started-with-the-tesla-xlights-project-directory&#34;&gt;section&lt;/a&gt; of the readme and imported it into xLights.  This pulls in the 3D car model with the 46 channels (lights, windows, doors, etc) that are configurable and provides a nice visual layout when testing out the light show in xLights.&lt;/p&gt;
&lt;p&gt;&lt;img src=&#34;https://jamessevedge.com/x-lights-overview.png&#34; alt=&#34;xLights Overview&#34;&gt;&lt;/p&gt;
&lt;h3 id=&#34;test-out-the-example-sequence&#34;&gt;Test out the example sequence&lt;/h3&gt;
&lt;p&gt;The Tesla engineering team provided an example &lt;a href=&#34;https://github.com/teslamotors/light-show#opening-the-example-sequence&#34;&gt;light show&lt;/a&gt; (not the same one loaded in the car) which you can use to get a feel for how the sequence effects are laid out and validate your USB can be plugged into the car and correctly play a custom light show.  I found this step useful to ensure I didn&amp;rsquo;t take the time to create a light show from scratch and end up running into an issue with USB disk format, etc.&lt;/p&gt;
&lt;p&gt;I downloaded the example, put it into &lt;code&gt;Downloads-&amp;gt;Tesla_Light_Show-&amp;gt;Smooth_Jazz-&amp;gt;LightShow&lt;/code&gt;, copied that folder over to the USB, plugged it into the car and tested it out.  Thankfully it worked the first time!  &lt;strong&gt;Note&lt;/strong&gt; that I had to wait for a progress bar at the bottom of the modal to complete before pressing play or it would play the last loaded light show.&lt;/p&gt;
&lt;h3 id=&#34;creating-my-own-light-show&#34;&gt;Creating my own light show&lt;/h3&gt;
&lt;p&gt;First I needed the audio file for the song I wanted to play.  It is surprisingly hard nowadays with streaming services like Spotify, Apple Music, etc. to just get a plain old mp3 anymore&amp;hellip; but Amazon Music to the rescue!  In a couple clicks I found the song, purchased the single and downloaded the mp3 file into a new folder under &lt;code&gt;Downloads-&amp;gt;Tesla_Light_Show-&amp;gt;Bang-&amp;gt;LightShow&lt;/code&gt;.&lt;/p&gt;
&lt;p&gt;Now this is where the fun part actually begins, I needed to create the .fseq file using xLights which contains all the effects matched up to the audio.  To do this I opened xLights, created a new sequence and imported the mp3 file.  I put on some headphones and proceeded to try and grok the xLights interface and add effects 10-15 seconds at a time.  Once I had a good chunk added I would play it back and modify the effects until they lined up with the audio (or close enough!).  Once I got through the first chorus, verse and bridge I was able to start chunking the sequences with copy/paste.  I would then overlay some additional effects to build the light show as it progressed through the song.&lt;/p&gt;
&lt;p&gt;According to the Tesla light show readme there is a max of 651 effects allowed and so they wrote a python validator script to help sequence authors figure out if they were within the parameters.  Once I completed the light show and saved the .fseq file to the LightShow folder I ran that tool.  Apparently I had a lot more effects I could still add, maybe I will revist this sequence again another time.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-bash&#34; data-lang=&#34;bash&#34;&gt;   $ python validator.py ~/Downloads/Tesla_Shows/Bang/LightShow/lightshow.fseq
   Found &lt;span style=&#34;color:#ae81ff&#34;&gt;3417&lt;/span&gt; frames, step time of &lt;span style=&#34;color:#ae81ff&#34;&gt;50&lt;/span&gt; ms &lt;span style=&#34;color:#66d9ef&#34;&gt;for&lt;/span&gt; a total duration of 0:02:50.850000.
   Used 45.23% of the available memory
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;Here is what the folder structure that was copied over to the USB drive looked like.&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-bash&#34; data-lang=&#34;bash&#34;&gt;├── LightShow
│   ├── lightshow.fseq
│   ├── lightshow.mp3
│   ├── lightshow.xsq
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;p&gt;And this is a preview of how the light show turned out.&lt;/p&gt;

&lt;div style=&#34;position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;&#34;&gt;
  &lt;iframe src=&#34;https://www.youtube.com/embed/M-SK5_alK1A&#34; style=&#34;position: absolute; top: 0; left: 0; width: 100%; height: 100%; border:0;&#34; allowfullscreen title=&#34;YouTube Video&#34;&gt;&lt;/iframe&gt;
&lt;/div&gt;

&lt;p&gt;If you have a Tesla and want to try this out you can download it from the very cool &lt;a href=&#34;https://teslalightshare.io/light-show/291&#34;&gt;teslalightshare.io&lt;/a&gt; site.&lt;/p&gt;
&lt;h3 id=&#34;recap&#34;&gt;Recap&lt;/h3&gt;
&lt;p&gt;I spent roughly 4 hours getting from no idea how to create a light show for my car to understanding and creating one from scratch so kudos to the Tesla engineering team for good documentation and picking a tool (xLights) that has a decent interface for creating a sequence.  I had a blast creating this light show and intend to create more in the future that makes full use of the advanced effects including tailgate open/close and light ramping.&lt;/p&gt;
&lt;p&gt;One final note is it did occur to me that it would be nice to have a single USB with multiple custom light shows and the display would provide a picker with the list of shows available.  I filed a Github RFE which was promptly closed as a dupe of &lt;a href=&#34;https://github.com/teslamotors/light-show/issues/8&#34;&gt;#8&lt;/a&gt;.  When I took a look at that issue it appears the team appreciated the suggestions but did not commit to implementing it.  So a typical Tesla response.&lt;/p&gt;

      <title>Red Light Green Light</title>

      <description>&lt;p&gt;I was listening to the Tim Ferriss Show &lt;a href=&#34;https://tim.blog/2021/09/09/sheila-heen&#34;&gt;podcast episode #532&lt;/a&gt; with Sheila Heen (Harvard Negotiation Project, co-author of Difficult Conversations: How To Discuss What Matters Most) and a specific story she told during the conversation really resonated with me and I have been thinking alot about it since I heard it. Below is the excerpt of that story in her own words.&lt;/p&gt;
&lt;hr&gt;
&lt;p&gt;&lt;em&gt;It reminds me, I sometimes tell this story about my eldest son. His name is Ben. He’s 22 now, but when he was about three, we were driving down the street. We stopped at a traffic light, and we were working on both colors and also traffic rules, because at the time we lived on kind of a busy street in Cambridge. So we’re stopped at the light. And I say, “Hey, Ben. What color is the light?” And he says, “It’s green.” I said, “Ben, we’re stopped at the light. What color is the light? Take a good look.” And he goes, “It’s green.” And when it turns, he says, “It’s red. Let’s go.”&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Now, the kid seemed bright in most other ways. So I just thought like, what is going on with him? My first hypothesis is maybe he’s color blind, which then that would be my husband’s fault. At least I thought at the time, it’s my husband’s fault. I’ve since been informed it would have been my fault.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;So I started collecting data. I’m running a little scientific experiment of my own. So I start asking him to identify red and green in other contexts, and he gets it right every time. And yet every time we come to a traffic light, he’s still giving me opposite answers, because I get a little obsessed with this.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;My second hypothesis, by the way, is that he is screwing with me, which I certainly had some data to support. This went on for about three weeks. It wasn’t until maybe three weeks later, and I think my mother-in-law was in town. So I was in the back seat sitting next to Ben, and we stopped at a traffic light. And I suddenly realized that from where he sits in his car seat, he usually can’t see the light in front of us, because the headrest is in the way or it’s above the level of the windshield, windscreen as they say in Europe. So he’s looking out the side window at the cross traffic light.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Now just think about the conversation from his point of view. He’s looking at the light, it’s green; I’m insisting that it’s red, and he’s like, you know, my mother seems right in most other ways, but she’s just wrong about this. The reason that that experience has stuck with me all these years is that it’s such a great illustration of the fact that where you sit determines what you see.&lt;/em&gt;&lt;/p&gt;
&lt;hr&gt;
&lt;p&gt;Great story right? I considered titling this &lt;strong&gt;where you sit determines what you see&lt;/strong&gt; since that seemed to be an appropriate TLDR but I opted for the pithier title, sorry couldn&amp;rsquo;t help it.  I am not going to pile on to the story with my own personal anecdotes since Sheila is a great story teller and I prefer to keep this short and sweet, but for anyone who may be frusturated because they are having an issue communicating with a colleague, spouse or friend about something… perhaps the problem has nothing to do with communication. Check your perspective!&lt;/p&gt;

      <title>SDK Generation from an OpenAPI Specification File</title>
      <link>https://jamessevedge.com/articles/sdk-generation-from-an-openapi-specification-file/</link>
      <pubDate>Wed, 01 Dec 2021 00:00:00 +0000</pubDate>
      <author>jjesc1031@gmail.com (James Sevedge)</author>
      <guid>https://jamessevedge.com/articles/sdk-generation-from-an-openapi-specification-file/</guid>
      <description>&lt;p&gt;Recently I spent a fair amount of time exploring the SDK generation space for a prototype our team was building at my current employer.  Along the way I captured a few thoughts which I will break down here about what SDK generation is and some ways to go about it.  Let&amp;rsquo;s get some context first by starting with a problem statement.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Problem Statement&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Let&amp;rsquo;s say we are responsible for the usability of a SaaS service at XYZ company which has a RESTful API, and since this service is taking off we have begun to get requests for a better developer user experience (UX).  Looking to peers in the industry with similar services a common composability pattern emerges, specifically something such as the following.&lt;/p&gt;
&lt;script src=&#34;https://unpkg.com/mermaid@8.5.1/dist/mermaid.min.js&#34;&gt;&lt;/script&gt;

&lt;script&gt;
    mermaid.initialize({ 
        theme: &#39;dark&#39;,
        maxWidth: true
    });
&lt;/script&gt;

&lt;pre class=&#34;mermaid&#34; align=&#34;center&#34;&gt;
graph TD;
    api_service[&#34;Native API Service (Imperative)&#34;];
    api_service_declarative[&#34;Native API Service (Declarative)&#34;];
    sdk_python[&#34;SDK Binding (Python)&#34;];
    sdk_go[&#34;SDK Binding (Go)&#34;];
    sdk_js[&#34;SDK Binding (Javascript)&#34;];
    cli[&#34;CLI (written in Go)&#34;];
    terraform[&#34;Terraform (written in Go)&#34;];
    ansible[&#34;Ansible (written in Python)&#34;];
    api_service_declarative --&gt; api_service;
    sdk_python --&gt; api_service;
    sdk_python --&gt; api_service_declarative;
    sdk_go--&gt; api_service;
    sdk_go --&gt; api_service_declarative;
    sdk_js--&gt; api_service;
    sdk_js --&gt; api_service_declarative;
    cli --&gt; sdk_go;
    terraform --&gt; sdk_go;
    ansible --&gt; sdk_python;
&lt;/pre&gt;
&lt;p&gt;This pattern is used by most of the major SaaS providers, to varying degrees of maturity.  It allows the developer UX to naturally evolve out and away from the core competencies (native API service + a declarative API service for companies that understand the customer value proposition of a declarative model and choose to provide that experience natively) to whatever integration point makes the most sense for the consumer of the service.&lt;/p&gt;
&lt;p&gt;The technical issue with this pattern of course is how to propagate out changes that occur in the core competencies to all the upstream bindings and external integration points automagically.  The assumption is in most cases it would not be feasible both from a manpower and delivery management perspective to try and do this without tooling and automation.  So let&amp;rsquo;s take some time to think about SDK generation since that is the set of bindings immediately upstream of the core APIs.&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Future Post&lt;/em&gt;: Once you have the SDK bindings problem solved you can use those in Terraform/Ansible and tackle the problem of if/how to automate updates to those providers/modules.  One step at a time though!&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Existing SDK Generation Tooling&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Most SDK generation tooling research starts by googling &amp;ldquo;SDK Generation Tool&amp;rdquo; and ends with finding &lt;a href=&#34;https://github.com/OpenAPITools/openapi-generator&#34;&gt;OpenAPI Generator&lt;/a&gt;, which is listed on &lt;a href=&#34;https://openapi.tools/#sdk&#34;&gt;openapi.tools&lt;/a&gt;.  OpenAPI Generator is probably the most popular open-source OpenAPI based SDK generator available, it was a fork of the original &lt;a href=&#34;https://swagger.io/tools/swagger-codegen/&#34;&gt;Swagger CodeGen&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;If you use one of these common generators they take an &lt;a href=&#34;https://www.openapis.org&#34;&gt;OpenAPI&lt;/a&gt; specification file which describes the service API endpoints in as much detail as you like and uses common properties such as HTTP methods, HTTP uri and so on to generate bindings for 1+ programming languages.  If the default output works for you without additional customization for company branding, etc. you can stop here.  If you either don&amp;rsquo;t want to learn how to customize those bindings (see &lt;a href=&#34;https://openapi-generator.tech/docs/templating/&#34;&gt;OpenAPI Generator templating&lt;/a&gt;) or you want to understand how SDK generation works in more detail let&amp;rsquo;s dive into the details.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Building an SDK Generator&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;In this section let&amp;rsquo;s walk through the steps I took to go from an OpenAPI specification document to a working set of python client bindings.&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Given a simple OpenAPI specification document&lt;/li&gt;
&lt;/ol&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-yaml&#34; data-lang=&#34;yaml&#34;&gt;&lt;span style=&#34;color:#f92672&#34;&gt;openapi&lt;/span&gt;: &lt;span style=&#34;color:#ae81ff&#34;&gt;3.0.0&lt;/span&gt;
&lt;span style=&#34;color:#f92672&#34;&gt;info&lt;/span&gt;:
  &lt;span style=&#34;color:#f92672&#34;&gt;title&lt;/span&gt;: &lt;span style=&#34;color:#ae81ff&#34;&gt;Example API Specification&lt;/span&gt;
  &lt;span style=&#34;color:#f92672&#34;&gt;description&lt;/span&gt;: &lt;span style=&#34;color:#ae81ff&#34;&gt;Example Description&lt;/span&gt;

            &lt;span style=&#34;color:#f92672&#34;&gt;url&lt;/span&gt;: &lt;span style=&#34;color:#ae81ff&#34;&gt;/applications&lt;/span&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;ol start=&#34;3&#34;&gt;
&lt;li&gt;Render that generator model against a language-specific template set (Mustache, etc.), in this case Python&lt;/li&gt;
&lt;/ol&gt;
&lt;pre&gt;&lt;code class=&#34;language-mustache&#34; data-lang=&#34;mustache&#34;&gt;&amp;quot;&amp;quot;&amp;quot;{{namespace}} Client&amp;quot;&amp;quot;&amp;quot;

from mysdk.base_clients import BaseFeatureClient

class {{namespace}}Client(BaseFeatureClient):
    &amp;quot;&amp;quot;&amp;quot;{{namespace}} Client &amp;quot;&amp;quot;&amp;quot;

    def __init__(self, client, **kwargs):
        &amp;quot;&amp;quot;&amp;quot;Initialization &amp;quot;&amp;quot;&amp;quot;

        super({{namespace}}Client, self).__init__(
            client,
            logger_name=__name__,
            uri=&#39;/&#39;
        )

    {{#operations}}
    def {{name}}(self, **kwargs):
        &amp;quot;&amp;quot;&amp;quot;{{description}}&amp;quot;&amp;quot;&amp;quot;

        {{#transportSettings.requestBodyRequired}}
        return self._make_request(
            method=&#39;{{transportSettings.method}}&#39;,
            uri=&#39;{{transportSettings.url}}&#39;,
            body=kwargs.pop(&#39;config&#39;, None)
        )
        {{/transportSettings.requestBodyRequired}}
        {{^transportSettings.requestBodyRequired}}
        return self._make_request(
            method=&#39;{{transportSettings.method}}&#39;,
            uri=&#39;{{transportSettings.url}}&#39;
        )
        {{/transportSettings.requestBodyRequired}}

    {{/operations}}
&lt;/code&gt;&lt;/pre&gt;&lt;ol start=&#34;4&#34;&gt;
&lt;li&gt;The render operation outputs the following functional SDK with a service client per namespace (group/tag/etc)&lt;/li&gt;
&lt;/ol&gt;

        )

        &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#34;&amp;#34;&amp;#34;Add a new application&amp;#34;&amp;#34;&amp;#34;&lt;/span&gt;

        &lt;span style=&#34;color:#66d9ef&#34;&gt;return&lt;/span&gt; self&lt;span style=&#34;color:#f92672&#34;&gt;.&lt;/span&gt;_make_request(

            body&lt;span style=&#34;color:#f92672&#34;&gt;=&lt;/span&gt;kwargs&lt;span style=&#34;color:#f92672&#34;&gt;.&lt;/span&gt;pop(&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#39;config&amp;#39;&lt;/span&gt;, &lt;span style=&#34;color:#66d9ef&#34;&gt;None&lt;/span&gt;)
        )
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;ol start=&#34;5&#34;&gt;
&lt;li&gt;Ship it!&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Seems pretty easy right?  Let&amp;rsquo;s look at some of the mappings:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;code&gt;path.method.tags[0]&lt;/code&gt; -&amp;gt; Class name (operation/method grouping)&lt;/li&gt;
&lt;li&gt;&lt;code&gt;path&lt;/code&gt; -&amp;gt; Method transport URI&lt;/li&gt;
&lt;li&gt;&lt;code&gt;path.method&lt;/code&gt; -&amp;gt; Method transport verb&lt;/li&gt;
&lt;li&gt;&lt;code&gt;path.method.operationId&lt;/code&gt; -&amp;gt; Method signature (name)&lt;/li&gt;
&lt;li&gt;&lt;code&gt;path.method.description&lt;/code&gt; -&amp;gt; Method description&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Of course this is the bare minimum necessary to generate a binding that could be useful, some other considerations that immediately present themselves are:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;What is necessary to define request/response interfaces for strongly typed languages?&lt;/li&gt;
&lt;li&gt;Do management clients (auth, low-level transport) need to be auto-generated?  If so what additional properties in the authentication endpoints (Basic, OAuth) OpenAPI specification files will need to be specified?&lt;/li&gt;
&lt;li&gt;How should APIs with support for async operations be handled?&lt;/li&gt;
&lt;li&gt;How would additional information such as namespace level usage examples be codified?&lt;/li&gt;
&lt;li&gt;How much logic should be considered MVP in the core package, such as authentication token refresh, transport level retries and so on?&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Most of this initial set of problems are solvable simply by determining the minimal set of properties necessary for each endpoint to generate the appropriate generation model, enforcing that set of properties with a linter and then creating the appropriate templates/tooling to make use of that model.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Industry SDK Generation Examples&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Here are some examples of popular industry API providers and the approach they took to SDK generation.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Microsoft Azure:
&lt;ul&gt;
&lt;li&gt;Specification Location: &lt;a href=&#34;https://github.com/Azure/azure-rest-api-specs&#34;&gt;https://github.com/Azure/azure-rest-api-specs&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;SDK Generator: &lt;a href=&#34;https://github.com/Azure/autorest&#34;&gt;https://github.com/Azure/autorest&lt;/a&gt;, &lt;a href=&#34;https://github.com/Azure/autorest/blob/master/docs/trampoline.md&#34;&gt;https://github.com/Azure/autorest/blob/master/docs/trampoline.md&lt;/a&gt;, &lt;a href=&#34;https://github.com/Azure/azure-rest-api-specs/tree/master/specification/compute/resource-manager&#34;&gt;https://github.com/Azure/azure-rest-api-specs/tree/master/specification/compute/resource-manager&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;AWS:
&lt;ul&gt;
&lt;li&gt;Specification Location: &lt;a href=&#34;https://github.com/boto/boto3/tree/master/boto3/data&#34;&gt;https://github.com/boto/boto3/tree/master/boto3/data&lt;/a&gt;, &lt;a href=&#34;https://github.com/aws/aws-sdk-js/blob/master/apis&#34;&gt;https://github.com/aws/aws-sdk-js/blob/master/apis&lt;/a&gt;,&lt;/li&gt;
&lt;li&gt;SDK Generator: It appears they manually define the &amp;ldquo;apis&amp;rdquo; and SDK methods using JSON and use that during generation&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;GCP:
&lt;ul&gt;
&lt;li&gt;Specification Location: &lt;a href=&#34;https://github.com/googleapis/googleapis&#34;&gt;https://github.com/googleapis/googleapis&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;SDK Generator: &lt;a href=&#34;https://google.aip.dev/client-libraries/4210&#34;&gt;https://google.aip.dev/client-libraries/4210&lt;/a&gt;, &lt;a href=&#34;https://github.com/googleapis/gapic-generator&#34;&gt;https://github.com/googleapis/gapic-generator&lt;/a&gt;, &lt;a href=&#34;https://github.com/googleapis/gapic-generator-python&#34;&gt;https://github.com/googleapis/gapic-generator-python&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;li&gt;Kubernetes
&lt;ul&gt;
&lt;li&gt;Specification Location: &lt;a href=&#34;https://github.com/kubernetes/kubernetes/tree/master/api/openapi-spec&#34;&gt;https://github.com/kubernetes/kubernetes/tree/master/api/openapi-spec&lt;/a&gt;, &lt;a href=&#34;https://github.com/kubernetes-client&#34;&gt;https://github.com/kubernetes-client&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;SDK Generator: It looks like they might be using openapi-generator with their own customization. Here are the scripts they are using to invoke the generator &lt;a href=&#34;https://github.com/kubernetes-client/gen&#34;&gt;https://github.com/kubernetes-client/gen&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;strong&gt;Final Thoughts&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;As previously stated the deeper you go down the rabbit hole the more you have to consider, but getting a working prototype of a custom SDK generator is not that difficult.  Most of the industry examples provided above ended up going down that route to provide the best developer UX possible for their customers since they have the scale and resourcing necessary.&lt;/p&gt;

      <title>An Excercise In Refactoring</title>

      <author>jjesc1031@gmail.com (James Sevedge)</author>
      <guid>https://jamessevedge.com/articles/an-excercise-in-refactoring/</guid>
      <description>&lt;p&gt;In my humble experience any discussion about refactoring should start with &lt;a href=&#34;https://martinfowler.com/books/refactoring.html&#34;&gt;Refactoring&lt;/a&gt; (Martin Fowler/Kent Beck) and &lt;a href=&#34;https://www.oreilly.com/library/view/clean-code-a/9780136083238/&#34;&gt;Clean Code&lt;/a&gt; (Robert Martin).  Having at least a rudimentary understanding of the design patterns presented in &lt;a href=&#34;https://www.amazon.com/gp/product/0201633612/ref=as_li_tl?ie=UTF8&amp;amp;camp=1789&amp;amp;creative=9325&amp;amp;creativeASIN=0201633612&amp;amp;linkCode=as2&amp;amp;tag=martinfowlerc-20&#34;&gt;Gang of Four&lt;/a&gt; is helpful too.&lt;/p&gt;
&lt;p&gt;It can be daunting to know where exactly to begin with those resources or understand why it matters so let&amp;rsquo;s dive into the following concrete example to provide some clarity on what refactoring a module &lt;em&gt;may&lt;/em&gt; look like.&lt;/p&gt;
&lt;h2 id=&#34;refactoring-excercise&#34;&gt;Refactoring Excercise&lt;/h2&gt;
&lt;p&gt;Let&amp;rsquo;s start with some code that could use a little (or a lot of!) refactoring…&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; style=&#34;color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4&#34;&gt;&lt;code class=&#34;language-javascript&#34; data-lang=&#34;javascript&#34;&gt;&lt;span style=&#34;color:#66d9ef&#34;&gt;const&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;axios&lt;/span&gt; &lt;span style=&#34;color:#f92672&#34;&gt;=&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;require&lt;/span&gt;(&lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#39;axios&amp;#39;&lt;/span&gt;);

&lt;span style=&#34;color:#66d9ef&#34;&gt;function&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;uploadFiles&lt;/span&gt;() {
    &lt;span style=&#34;color:#66d9ef&#34;&gt;const&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;loginResponse&lt;/span&gt; &lt;span style=&#34;color:#f92672&#34;&gt;=&lt;/span&gt; &lt;span style=&#34;color:#66d9ef&#34;&gt;await&lt;/span&gt; &lt;span style=&#34;color:#a6e22e&#34;&gt;axios&lt;/span&gt;({
        &lt;span style=&#34;color:#a6e22e&#34;&gt;url&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;:&lt;/span&gt; &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#39;https://the-cloud/api/v1/login&amp;#39;&lt;/span&gt;,
        &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#39;GET&amp;#39;&lt;/span&gt;,
        &lt;span style=&#34;color:#a6e22e&#34;&gt;auth&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;:&lt;/span&gt; {
            &lt;span style=&#34;color:#a6e22e&#34;&gt;username&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;:&lt;/span&gt; &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#39;a_username&amp;#39;&lt;/span&gt;,
            &lt;span style=&#34;color:#a6e22e&#34;&gt;password&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;:&lt;/span&gt; &lt;span style=&#34;color:#e6db74&#34;&gt;&amp;#39;a_password&amp;#39;&lt;/span&gt;
        },
        &lt;span style=&#34;color:#a6e22e&#34;&gt;validateStatus&lt;/span&gt;&lt;span style=&#34;color:#f92672&#34;&gt;:&lt;/span&gt; &lt;span style=&#34;color:#66d9ef&#34;&gt;false&lt;/span&gt;
    });
    &lt;span style=&#34;color:#66d9ef&#34;&gt;if&lt;/span&gt; (&lt;span style=&#34;color:#a6e22e&#34;&gt;loginResponse&lt;/span&gt;.&lt;span style=&#34;color:#a6e22e&#34;&gt;status&lt;/span&gt; &lt;span style=&#34;color:#f92672&#34;&gt;!==&lt;/span&gt; &lt;span style=&#34;color:#ae81ff&#34;&gt;200&lt;/span&gt;) {
        &lt;span style=&#34;color:#66d9ef&#34;&gt;throw&lt;/span&gt; &lt;span style=&#34;color:#66d9ef&#34;&gt;new&lt;/span&gt; Error(&lt;span style=&#34;color:#e6db74&#34;&gt;`HTTP request failed: &lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt;${&lt;/span&gt;&lt;span style=&#34;color:#a6e22e&#34;&gt;loginResponse&lt;/span&gt;.&lt;span style=&#34;color:#a6e22e&#34;&gt;status&lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt;}&lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt; &lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt;${&lt;/span&gt;&lt;span style=&#34;color:#a6e22e&#34;&gt;loginResponse&lt;/span&gt;.&lt;span style=&#34;color:#a6e22e&#34;&gt;data&lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt;}&lt;/span&gt;&lt;span style=&#34;color:#e6db74&#34;&gt;`&lt;/span&gt;)
    }

&lt;p&gt;Actions To Take: 1) Extract out &lt;code&gt;login&lt;/code&gt; functionality and use it in &lt;code&gt;uploadFiles&lt;/code&gt; 2) Extract out &lt;code&gt;_generateAndUploadFile&lt;/code&gt; functionality and use it in &lt;code&gt;uploadFiles&lt;/code&gt;&lt;/p&gt;

&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;h2 id=&#34;futher-optimizations&#34;&gt;Futher optimizations&lt;/h2&gt;
&lt;p&gt;There is more that can be done to this code of course, such as 1) moving the low level cloud service API interaction to a &lt;code&gt;CloudApiClient&lt;/code&gt; class to encapsulate that functionality (and allow support via polymorphism for another cloud) 2) creating a &lt;code&gt;FilesClient&lt;/code&gt; class to encapsulate cloud service file operation behavior 3) wrapping the top level certificate and key upload business logic into a class which handles loading the files from the environment and calling the other classes 4) and so on…&lt;/p&gt;
&lt;script src=&#34;https://unpkg.com/mermaid@8.5.1/dist/mermaid.min.js&#34;&gt;&lt;/script&gt;

&lt;script&gt;
    mermaid.initialize({ 
        theme: &#39;dark&#39;,
        maxWidth: true
    });
&lt;/script&gt;

&lt;pre class=&#34;mermaid&#34; align=&#34;center&#34;&gt;
classDiagram
    class CloudApiClient{
        +login()
        +makeRequest()
    }
    class FilesClient{
        +init()
        +uploadFile()
    }
    class CertificateAndKeyUploader{
        +uploadFiles()
    }
    CertificateAndKeyUploader ..&gt; FilesClient
    FilesClient ..&gt; CloudApiClient
&lt;/pre&gt;
&lt;p&gt;but this at least covers the broad strokes of what refactoring a module might look like.&lt;/p&gt;
&lt;h2 id=&#34;additional-resources&#34;&gt;Additional Resources&lt;/h2&gt;
&lt;p&gt;I find that once you have a foundational understanding of code refactoring, you simply need to excercise that knowledge over time to get better… but to get a refresher on specific principles you can go to the wonderful site &lt;a href=&#34;https://refactoring.com&#34;&gt;refactoring.com&lt;/a&gt; and check out the &lt;a href=&#34;https://refactoring.com/catalog/&#34;&gt;catalog&lt;/a&gt;.  I also highly recommend, when the time is right, to find and spend the time to watch the &amp;ldquo;Uncle Bob&amp;rdquo; Clean Code &lt;a href=&#34;https://www.youtube.com/watch?v=7EmboKQH8lM&#34;&gt;series&lt;/a&gt; where he goes into detail about the topics covered in his book.&lt;/p&gt;

      <title>Treat your Career Like a Startup</title>
      <link>https://jamessevedge.com/articles/career-as-a-startup/</link>
      <pubDate>Tue, 19 Oct 2021 00:00:00 +0000</pubDate>
      <author>jjesc1031@gmail.com (James Sevedge)</author>
      <guid>https://jamessevedge.com/articles/career-as-a-startup/</guid>
      <description>&lt;p&gt;Lately I have been having discussions with both close friends and distant acquaintances on &amp;ldquo;leveling up&amp;rdquo; in your career, along the way I have formulated a few thoughts on this topic.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Do the job you want, not the job you have&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;It is a well understood concept that you should start doing elements of the job you would like to be promoted into before you get the promotion, so figure out what those elements are and do them when opportunity allows.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Raise your hand&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Is there a project that your management team has talked about but doesn&amp;rsquo;t know who to assign it to?  Raise your hand.  Is there a learning opportunity relevant to your organization&amp;rsquo;s needs that you can attend and bring back useful information?  Raise your hand.  Is there a project that requires a little travel to a different site?  Raise your hand.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Level up your organizations knowledge&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;While doing the work expected of your current role, figure out what knowledge you could learn and bring back into the team to help the organization level up.  It could be a new tool/library, testing methodology, way of working or anything else as long as it has some direct relevance.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Level up your knowledge&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;This is the most important one, do whatever it takes to continuously learn and surround yourself with peers who have the knowledge you would like to have.  If you feel it has been awhile since you have learned something new, find something and spend a little (or a lot!) of time getting proficient at it.  Always learning, always growing should be the mantra.&lt;/p&gt;
&lt;p&gt;&lt;em&gt;Qualifying statement&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Let me qualify these statements by making clear that deriving satisfaction from work output and career trajectory is great, but there is more to life than a career so put this advice into context.  Aspire to have balance in all things.&lt;/p&gt;

      <title>API Development (Beyond the Specification Document)</title>
      <link>https://jamessevedge.com/articles/api-development-to-customer-ux/</link>
      <pubDate>Wed, 20 May 2020 00:00:00 +0000</pubDate>
      <author>jjesc1031@gmail.com (James Sevedge)</author>
      <guid>https://jamessevedge.com/articles/api-development-to-customer-ux/</guid>
      <description>&lt;p&gt;Creating an API that is well thought out, scales and adopts industry standards can be quite difficult.  Creating the API while keeping the end consumer User Experience (UX) at the forefront adds even more cognitive load, however the payoff is worth it to stay disciplined and consider it from the start.  Let&amp;rsquo;s talk about what that flow might look like at a high level including some example tooling and processes.&lt;/p&gt;
&lt;p&gt;First let&amp;rsquo;s assume you have a good API design in place which has been peer-reviewed and articulated in a human and machine readable format, for example if creating a REST API you may articulate this using &lt;a href=&#34;https://openapis.org/&#34;&gt;OpenAPI&lt;/a&gt;, &lt;a href=&#34;https://apiblueprint.org/&#34;&gt;API Blueprint&lt;/a&gt; or some other similar mechanism.  In this example let&amp;rsquo;s assume you have been using OpenAPI.&lt;/p&gt;
&lt;p&gt;If the OpenAPI specification document describes your API, let&amp;rsquo;s strive to keep it that way.  That is the &lt;em&gt;source of truth&lt;/em&gt;.  Given that assumption all consumer UX should be derived from that document.&lt;/p&gt;
&lt;p&gt;Ok great, but my API is already implemented so what more is needed here?  And who is this mysterious &amp;ldquo;consumer&amp;rdquo; that demands more than simply a running instance of the API?&lt;/p&gt;
&lt;p&gt;The most common consumer of API&amp;rsquo;s is other developers trying to make use of your technology platform to accomplish a specific set of tasks which fit into a larger goal.  To enable adoption of the API you must consider a variety of artifacts, including API documentation, hand-crafted examples to describe certain 80/20 usage patterns, multi-language binding SDK bindings and more.&lt;/p&gt;
&lt;p&gt;Before picking any specific tool you need to do research to ensure any tooling selected makes good design sense (more on that later).  One such resource is &lt;a href=&#34;https://openapi.tools&#34;&gt;https://openapi.tools&lt;/a&gt;.  That being said let&amp;rsquo;s take a look at the below UML flow diagram and then map that to a specific tool.&lt;/p&gt;
&lt;script src=&#34;https://unpkg.com/mermaid@8.5.1/dist/mermaid.min.js&#34;&gt;&lt;/script&gt;

        maxWidth: true
    });

&lt;p&gt;As you can see everything in this diagram flows from the API specification document which should be considered the &lt;em&gt;source of truth&lt;/em&gt;, that being said there is still plenty of work and tooling required to get to a polished consumer UX beyond just writing an API specification document.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;API Documentation Generator: &lt;a href=&#34;https://github.com/Redocly/redoc&#34;&gt;ReDoc&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Curated Consumer Documentation: &lt;a href=&#34;https://github.com/gohugoio/hugo&#34;&gt;Hugo&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;SDK Generator: &lt;a href=&#34;https://github.com/OpenAPITools/openapi-generator&#34;&gt;OpenAPI Generator&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;Thankfully there is open-source tooling which is available for use, you just have to pick a tool for the problem and hope that when you hit a blocker you will have used it and understand it enough to be able to contribute changes back.&lt;/p&gt;
