<p>Needed to concatenate several CSV files in S3. Downloading them would be costly (both on time and money cost). There are scripts that do it without downloading, by using “multi-part upload“ from S3 to S3. See: #s3fs.core.S3FileSystem.merge and </p>

<p>Needed to get the row count of a huge CSV file in S3 without downloading it. It’s possible by using S3 Select functionality! It makes CSV and JSON files queryable with a SQL-like syntax. See: #S3.Client.select_object_content</p>

<p>s3fs is an awesome Python library that makes working with AWS S3 as easy as working with local files: </p>

<p>Fun Vim shortcut of the day: <code>map &lt;F7&gt; :!pytest %&lt;CR&gt; "Run pytest for the current file on buffer</code></p>

<p>What are coachmarks, and how they can improve the user experience </p>

<p>Identify your slowest test set using pytest by using the flag <code>--duration</code>, e.g. <code>--duration=50</code> will report the 50 slowest test set from a given test suite. Refer to: #profiling-test-execution-duration</p>
