<p>Today I and a friend went down a rabbit hole about Rust and how it manages the heap when we use <code class="language-plaintext highlighter-rouge">Box</code>, or <code class="language-plaintext highlighter-rouge">String</code>, or <code class="language-plaintext highlighter-rouge">Vec</code>, and while we were at it, I found out there is such a thing as <code class="language-plaintext highlighter-rouge">Box<str></code>, which might look a bit <em>strange</em> to an untrained eye, since most of the time the <code class="language-plaintext highlighter-rouge">str</code> primitive type is passed around as <code class="language-plaintext highlighter-rouge">&str</code>.</p>

There I stumbled upon <a href="https://wiki.haskell.org/Typeclassopedia">Typoclassopedia</a>, while the material is great, I couldn’t find solutions for the exercises to check against, so I decided I would write my own and hopefully the solutions would get fixed in case I have gone wrong by others.

<p>I’ve had a Kindle for more than a year now, but I’ve only recently started to read books on it frequently, I used to read paperworks before that, and I still do sometimes prefer paperbooks if available. Anyways, my Kindle has helped me to fall asleep without struggling with all my thoughts, all I have to do is read until I fall asleep, so in a way, it has also been a remedy for my insomnia.</p>
|
||
|
||
<p>Now to read the Kindle in bed, you would have to hold it using your hands or buy a stand or make one, motivated by <a href="https://blog.xkcd.com/2009/04/13/the-pursuit-of-laziness/">The Pursuit of Laziness</a> I set to create mine, but I didn’t use a piece of steel, instead I used a single box of cardboard I had in home to create one in minutes. :D</p>

<p>I just want to leave this here as I often tend to look it up myself and the first time it was not as easy to figure out.</p>
|
||
|
||
<p>When using Travis CI along with GitHub (or other git integrations), Travis runs two tests: <code>pr</code> and <code>push</code>.</p>
|
||
|
||
<p><img src="/img/travis-ci-pr-push-github.jpg" alt="travis-pr-push-github" /></p>
|
||
|
||
<p>Most of the time you see both tests passing and you do not have to even wonder how they are different, but it has
|
||
happened to me that one of the tests fails while the other passes and I started to wonder why.</p>
|
||
|
||
<h3 id="pr">pr</h3>
|
||
<p>The <code>pr</code> test is a test run on the result of a merge between the pull-request branch and the main branch.
|
||
As an example, let’s say your pull-request’s branch is called <code>fix-user-auth</code> and your main branch is <code>master</code>,
|
||
in this case, <code>pr</code> merges <code>fix-user-auth</code> into <code>master</code> and then runs the tests on the result of the merge.</p>
|
||
|
||
<h3 id="push">push</h3>
|
||
<p>On the other hand, <code>push</code> is run on the pull-request branch itself, without merging. So in our example above, Travis would checkout to <code>fix-user-auth</code> and run the tests.</p>
|
||
|
||
<h3 id="a-case-of-difference">A case of difference</h3>
|
||
|
||
<p>A case in which this difference might be more apparent is when your pull-request is based on a branch other than <code>master</code>, and some changes that your pull-request depends on are missing from <code>master</code>, in this case the <code>push</code> test may pass, but the <code>pr</code> test will fail.</p>

<p>I decided I’m going to share the lessons I’ve learned in each trip as they are certainly going to be useful if you want to practice primitive living, I would find these useful if I could find them anywhere. I spend a lot of time reading and watching primitive living guides and experience reports, but they are never exhaustive, and this series is not meant to be exhaustive either.</p>
