We won't be far behind if C-22 passes. In its current state, VPNs would almost certainly require us to log identifying user data. Signal isn't headquartered in Canada so they can just shut off Canadian servers, but our HQ is. We pay an ungodly amount of taxes to this corrupt government, and in return they want to destroy the entire essence of our service to basically spy on its own citizens. Not happening. We'll move HQ and take our taxes elsewhere.








I understand why everyone is dunking on Richard Dawkins, but fairness compels me to speak up: If you took a complex project you were working on, uploaded it to Claude, and had a 3-day conversation about it, you wouldn't be making fun of Dawkins for saying it's conscious.












Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.





Anthropic CEO (Dario Amodei): "Coding is going away first, then all of software engineering." What do you think about this?



COLUMN: Is Canada becoming a one-party state? While the federal Liberals smugly refer to themselves as Canada’s natural governing party, the historical record suggests it may be true, despite the danger it poses to democracy. torontosun.com/opinion/column…
