Help improve Pony Foo Weekly! We’ve been mixing web development content with interesting articles about software engineering topics in general, such as operations, AI, and architecture. Do you believe these links have a place in Pony Foo Weekly, or would you like it to be more focused?  Bill Benter did the impossible: He wrote an algorithm that couldn’t lose at the track. Close to a billion dollars later, he tells his story for the first time. An absolutely fascinating article on the topic of algorithmic betting, and one of its pioneers, William Benter, betting on the Hong Kong Jockey Club Race track circa 1985. A paper by the same person, “Computer Based Horse Race Handicapping and Wagering Systems: a Report” contains a recap of his learnings and a fountain of knowledge referenced to this day. |

This seems to be a rare escape hatch, with Duplex understanding nuanced conversations to a degree we haven’t seen before, making for fluid and natural conversation. |  |

Every now and then you find yourself wanting to extract quoted strings, HTML tags or something in-between curly braces from a bigger string of text. While it would be more robust, maintainable and readable to write proper parser, regular expressions are often chosen as a quick solution. |  |

We were all introduced to the env() function in CSS when all that drama about “The Notch” and the iPhone X was going down. The way that Apple landed on helping us move content away from those “unsafe” areas was to provide us with what amounted to hard-coded variables. Now there’s a proposal for env(). |
