This year it appears that <strong>Docker is becoming a similar fundamental tool for Professional Developers</strong>, increasing from 55% to 69%.</li> <li>Language: <strong>Rust</strong> is […] <strong>the most loved language</strong> with 87% of developers saying they want to continue using it.</li> <li>JS Frameworks: <strong>Angular.js is in its third year as the most dreaded</strong>.</li> <li>Let me Google that for you: 62% of all respondents <strong>spend more than 30 minutes a day searching for answers</strong> or solutions to problems. 25% spending more than an hour each day. </li> <li>The demise of the full-stack developer <a href="https://survey.stackoverflow.co/2022/#section-developer-roles-developer-type">is overrated</a>.</li> <li>I do wish <a href="https://survey.stackoverflow.co/2022/#section-demographics-gender">there were more women</a> in the field.</li> <li><strong>Databases</strong>: Postgres is #1 and MongoDB is still going strong.</li> <li>The “<a href="https://survey.stackoverflow.co/2022/#section-most-popular-technologies-web-frameworks-and-technologies">which web framework do you use</a>?” question is a full on train wreck. Why is this so hard for people to write the question? Node.js or Express (built on Node) vs. FastAPI or Flask (but no Python?)</li> <li>Most wanted / loved language is Rust (wanted) and <strong>Python/Rust tied for most wanted</strong>.</li> <li><a href="https://survey.stackoverflow.co/2022/#section-worked-with-vs-want-to-work-with-programming-scripting-and-markup-languages">Worked with vs. want to work with</a> has some interesting graphics.</li> </ul> <p><strong>Brian #2:</strong> <a href="https://pepy.tech"><strong>PePy.tech - PyPI download stats with package version breakdown</strong></a></p> <ul> <li>Petru Rares Sincraian</li> <li>We’ve discussed pypistats.org before, which highlights <ul> <li>daily downloads</li> <li>downloads per major/minor Python version</li> <li>downloads per OS</li> </ul></li> <li>PyPy is a bit more useful for me <ul> <li>default shows last few versions and total for this major version</li> <li>“select versions” box is editable. <ul> <li>clicking in it shows dropdown with downloads per version already there</li> <li>you can add <code>*</code> for graph of total</li> <li>or other major versions if you want to compare</li> </ul></li> <li>daily/weekly/monthly is nice, to round out some noise and see larger trends</li> <li>Oddity I noticed - daily graph isn’t the same dates as the table. <ul> <li>off by a day on both sides</li> <li>not a big deal, but I notice these kinds of things.</li> </ul></li> </ul></li> </ul> <p><strong>Michael #3:</strong> <a href="https://github.com/exaloop/codon"><strong>Codon Python Compiler</strong></a></p> <ul> <li>via Jeff Hutchins and Abdulaziz Alqasem</li> <li>A high-performance, zero-overhead, extensible Python compiler using LLVM </li> <li>You can scale performance and produce executables, even when using third party libraries such as matplotlib. </li> <li>It also supports writing and executing GPU kernels, which is an interesting feature.</li> <li>See how it works at <a href="https://exaloop.io">exaloop.io</a></li> <li>BTW, <strong>really terrible licensing</strong>. <ul> <li>Free for non-commercial (great)</li> <li>“Contact us” for commercial use (it’s fine to charge, but give us a price)</li> </ul></li> </ul> <p><strong>Brian #4:</strong> <a href="https://medium.com/techtofreedom/8-levels-of-using-type-hints-in-python-a6717e28f8fd"><strong>8 Levels of Using Type Hints in Python</strong></a></p> <ul> <li><a href="https://medium.com/@yangzhou1993?source=post_page-----a6717e28f8fd--------------------------------">Yang Zhou</a> (yahng cho)</li> <li>A progression of using type hints that seems to track how I’ve picked them up</li> </ul> <ol> <li>Type Hints for Basic Data Types. <ul> <li><code>x: int</code></li> </ul></li> <li>Define a Constant Using Final Type <ul> <li><code>DB: Final =</code> <code>'``PostgreSQL'</code></li> <li>(ok.
