My kid had to learn the square roots up to 20 for a school test.
Her teacher mentioned she would ask her own kid questions throughout the day to help it memorize them. That gave me the idea to build an app that would do exactly that.

Staatssecretaris van Marum is door de bocht. De Amerikanen kunnen wél toegang krijgen tot #DigiD. Dat antwoordt hij vandaag op Kamervragen, n.a.v. de aangekondigde overname van Solvinity – beheerder van DigiD – door het Amerikaanse Kyndryl. Ik heb getekend. Jij?

I believe ChatGPT is on the same trajectory as Slack in the enterprise. While it has the best user experience, the fact both Copilot & Gemini are deeply integrated into their respective product suites will trump user experience.
I also expect OpenAI to similarly complain to regulators at some point

A tariff on movies is a tariff on software. Nobody moves rolls of film copies around anymore. That's a very slippery slope to step onto.
President Trump said Monday that he would impose a 100 percent tariff on foreign movies.
It is unclear when any of the tariffs would take effect, what specific goods they would apply to, and what legal authorities Trump would rely upon in imposing them.

Trump repeats threat to tax foreign films, suggests move on furniture imports
Trump’s latest tariff threats target foreign movies and furniture imports, citing national security concerns and alleged theft of the U.S. movie-making business.
