<p><strong><a href="https://fnands.com/blog/2024/mojo-png-parsing/">Parsing PNG images in Mojo</a></strong></p> It’s still very early days for Mojo, the new systems programming language from Chris Lattner that imitates large portions of Python and can execute Python code directly via a compatibility layer.</p> <p>Ferdinand Schenck reports here on building a PNG decoding routine in Mojo, with a detailed dive into both the PNG spec and the current state of the Mojo language. <p><small></small>Via <a href="https://news.ycombinator.com/item?id=40328338">Hacker News</a></small></p> <p>Tags: <a href="https://simonwillison.net/tags/png">png</a>, <a href="https://simonwillison.net/tags/python">python</a>, <a href="https://simonwillison.net/tags/mojo">mojo</a></p>

<p><strong><a href="https://www.fast.ai/posts/2023-05-03-mojo-launch.html">Mojo may be the biggest programming advance in decades</a></strong></p> Jeremy Howard makes a very convincing argument for why the new programming language Mojo is a big deal.</p> <p>Mojo is a superset of Python designed by a team lead by Chris Lattner, who previously created LLVM, Clang and and Swift.</p> <p>Existing Python code should work unmodified, but it also adds features that enable performant low-level programming—like “fn” for creating typed, compiled functions and “struct” for memory-optimized alternatives to classes.</p> <p>It’s worth watching Jeremy’s video where he uses these features to get more than a 2000x speed up implementing matrix multiplication, while still keeping the code readable and easy to follow.</p> <p>Mojo isn’t available yet outside of a playground preview environment, but it does look like an intriguing new project. <p><small></small>Via <a href="https://twitter.com/hamelhusain/status/1653963183013634048">@hamelhusain</a></small></p> <p>Tags: <a href="https://simonwillison.net/tags/programming-languages">programming-languages</a>, <a href="https://simonwillison.net/tags/python">python</a>, <a href="https://simonwillison.net/tags/ai">ai</a>, <a href="https://simonwillison.net/tags/mojo">mojo</a>, <a href="https://simonwillison.net/tags/jeremy-howard">jeremy-howard</a></p>
