I’m a long-time solver of Rosetta code problems for Mathematica (and later Wolfram Language). I’ve done hundreds of entries, with the earliest entries in 2009. See also the [other community post](https://wolfram.discourse.group/t/2321/1) on this topic. In this roughly ~1 hour episode I solve these problems: - [Halt and catch fire](http://www.rosettacode.org/wiki/Halt_and_catch_fire) - [Ultra useful primes](http://www.rosettacode.org/wiki/Ultra_useful_primes) - [Periodic table](http://www.rosettacode.org/wiki/Periodic_table) - [Earliest difference between prime gaps‎](http://www.rosettacode.org/wiki/Earliest_difference_between_prime_gaps) - [Pell numbers](http://www.rosettacode.org/wiki/Pell_numbers) Click here to watch: ![Logo.jpg](https://global.discourse-cdn.com/wolfram/original/3X/3/2/3228738c88e08bb33c30d76adc0a2b9eda1642ad.jpeg) ---
