407: Our Own CDN
Robert and Chris jump on to talk about own own little CDN project. Maybe that’s not the right term, but we struggled with naming it. Truth be told, it’s the /public/ folder in our monorepo, where the purpose is getting files to the world wide internet at URLs that anyone
Read moreImpossible rational triangles
A rational triangle is a triangle whose sides have rational length and whose area is rational. Can any two rational numbers be sizes of a rational triangle? Surprisingly no. You can always find a third side of rational length, but it might not be possible to do so while keeping
Read moreBuilding AI for consumer applications isn’t all fun and games
Kylan Gibbs, CEO of Inworld, joins the show to discuss the technical challenges of creating interactive AI for virtual worlds and games, the significance of user experience, and the importance of accessibility and cost-efficiency in deploying AI models.

The most important mathematical function after the basics is the gamma function. If I could add one function to a calculator that has trig functions, log, and exponential, it would be the gamma function. Or maybe the log of the gamma function; it’s often more useful than the gamma function
Read moreVanity addresses
Bitcoin addresses are essentially hash values of public keys encoded in Base58. More details here. The addresses are essentially random characters chosen from the Base58 alphabet: uppercase and lowercase Latin letters and digits, with 0 (zero), I (capital I), O (capital O), and l (lowercase l) removed to prevent errors.

David Darnes made a <code-pen> web component, which is a basic HTML/CSS/JS panel layout that renders them into an iframe (using the very cool <syntax-highlight> web component as well). Then it ate itself when Ariel Salminen put a <code-pen> in a <code-pen>. Then the universe collapsed upon itself when Rob
Read moreAn integral theorem of Gauss
Gauss proved in 1818 that the value of integral is unchanged if x and y are replaced by (x + y)/2 and √(xy), i.e. if you replaced x and y with their arithmetic mean and geometric mean [1]. So, for example, if you wanted to compute you could instead compute Notice that the coefficients of

The treasury of El Salvador owns over 6,000 Bitcoins. Its total holdings are currently worth roughly $700,000,000. These coins had been associated with one private key. Yesterday El Salvador announced that it would split its funds into 14 wallets in order to protect the funds from quantum computing. You can
Read moreHow quantum computing would effect Bitcoin
Bitcoin relies on two kinds of cryptography: digital signatures and hash functions. Quantum computing would be devastating to the former, but not the latter. To be more specific, the kind of digital signatures used in Bitcoin could in theory be broken by quantum computer using Shor’s algorithm. Digital signatures could
