Please, study your Bible. Not just the verses that make you feel good, or the ones that fit your current situation. Study the difficult passages too. Understand the context. Ask questions. Seek wisdom. You cannot build a deep relationship with a God whose Word you barely know.

I’m making a programming language called blood. Faster than rust, a powerful type system, all the power of effect systems, metaprogramming, zero-cost worktrees, semantic merging, sqlite-stored content-addressable code. Psychosis? Hopefully not. blood-lang.org

You haven’t seen generational wealth until you’ve seen this Toronto job posting. Pay: $50K CAD ($35K USD) — Lead Full-Stack Engineer. You’ll own the entire SaaS platform, lead engineering, manage payments, architecture, and legacy migrations. Benefits: On-site parking. Your car is the only thing getting equity.

🇨🇦 DEAR CANADIANS OBSESSED WITH AMERICAN POLITICS: A friendly reminder. You are not an American citizen. You don’t vote in American elections. You don’t elect the American president. Yet some of you follow Washington more closely than Ottawa and know more about Trump than your own MP. Meanwhile, back home: 🏠 Housing remains unaffordable. 💸 Taxes consume a substantial share of your income. 🏥 Healthcare wait times remain a serious concern. 🛒 Groceries keep draining household budgets. 💰 Government debt continues to grow. And somehow, every Canadian problem becomes Donald Trump’s fault. Here’s a revolutionary thought. America’s president is responsible for governing America. Canada’s prime minister is responsible for governing Canada. Yes, American policies affect us. Trade, tariffs and foreign policy matter. But they cannot explain away every domestic policy failure. You can dislike Trump without making him your entire personality. You can support Trump without treating him like Canada’s prime minister. And you can disagree with both without losing your mind. Canada needs citizens who scrutinize Ottawa as passionately as they obsess over Washington. Because the politicians who actually control much of your taxes, healthcare, housing policy and public spending are right here at home. 🇨🇦 Stop treating American politics like a spectator sport while Canadian politics determines your standard of living. #Canada #cdnpoli

Please stop calling me Maple MAGA. I’m MCGA .. Make Canada Great Again. 🇨🇦🏴‍☠️ My extremist demands include affordable groceries, a functioning healthcare system, reasonable taxes and a house that doesn’t require generational wealth. Apparently, that’s far-right radicalism in Canada now. 😉 🍁🫡🍁

my spidey senses are telling me the labs are, as we speak, using unguardrailed versions of their unreleased models to systematically reverse-engineer ALL of the internet’s software, apps, and games, then feeding the reconstructed source code straight into their training pipelines while simultaneously building guardrails to ladder-pull the rest of us

We added two sentences to Claude Code's prompt on Opus 5.5 to steer it away from recreating someone else's specific game because using Claude to infringe IP is against our usage policy. Original games, genre games, and games built from your own designs and assets are meant to keep working. We'll continue to iterate to ensure we're striking the right balance. In the meantime, if Claude turns down something that's yours, send it my way.

I suspect this will be Carneys first big mistake. No matter how the govt/media is trying to position this, Canadians are not in favor
