      <description>&lt;p&gt;The age-old question: Which IDE should you use? Well, the one you work best with!&lt;/p&gt;
&lt;p&gt;I’m a longtime and happy PyCharm user, but sometimes I look jealously at Visual Studio Code for its devcontainer and Jupyter Notebook support. Then I realize I’d miss some of the bread-and-butter features and workflows that, for me, are still unmatched in PyCharm. Anyway, I found a comparison of some Python IDEs for those who haven’t had the chance to test them all out: &lt;a href=&#34;https://www.infoworld.com/article/2250631/review-7-python-ides-compared.html&#34;&gt;www.infoworld.com/article/2&amp;hellip;&lt;/a&gt;&lt;/p&gt;

      <description>&lt;p&gt;Today was election day in Austria, and the online streaming service (#ORFon) of the Austrian public broadcasting agency (#ORF) is #down. If you&amp;rsquo;re curious how such a failure could be prevented, this is exactly what auto-scaling is for—automatically covering seasonal or event-based load peaks.&lt;/p&gt;

      <description>&lt;p&gt;I am not a native speaker, but the following sentence feels overly complicated: &amp;ldquo;if there is no un-ignored taint&amp;hellip;&amp;rdquo; #readingtechdocsasbedtimestory&lt;/p&gt;

      <description>&lt;p&gt;Curious to see this year&amp;rsquo;s selection of hot topics in software development especially in the area of web development at the WeAreDevelopers world congress.
