Guru's Tech Bytes — Episode 60

Good morning, it's Tuesday. This is Guru's Tech Bytes, episode 60. We got Instagram weirdness, Stanford homework that looks like it bench-presses GPUs, AI agents getting classroom rules, and Wall Street trying to fit Anthropic, SpaceX, and OpenAI into one of those little airplane overhead bins. So, pour the coffee and make sure Windows Update is not staring at you from the corner. First up... the newest Instagram exploit is apparently so goofy it sounds less like Ocean's Eleven and more like your cousin Vinny finding the spare key under the flowerpot. A researcher says Meta's account recovery flow let attackers wriggle into accounts through silly edge cases, which is the exact phrase that makes security teams reach for the antacids. When the world's family-photo machine can be poked with cartoon logic, everybody gets reminded that identity systems are only as strong as their weirdest reset button. Second... Stanford's CS336, Language Modeling from Scratch, is out there showing people how the sausage gets made, except the sausage is matrix multiplication and the grill costs more than my truck. The course walks through tokenizers, transformers, training loops, and evaluation, which is great because half the industry is currently saying “AI model” like it's a magic toaster. If you want to understand why these things talk so smooth and still occasionally eat glue, this is a useful map. Third... the CS336 folks also posted AI agent guidelines, because even the robots doing the homework need a syllabus now. It lays down how students can use Claude-style agents without pretending the agent's work is their own, which feels sane: use the calculator, don't marry the calculator and put its name on the diploma. Heh. Hhh, okay, that's something. The bigger signal is that agentic coding is normal enough now that schools are writing policy instead of just waving a broom at it. And finally... The Economist asks whether the stock market can swallow Anthropic, SpaceX, and OpenAI. That is a fancy finance way of asking whether everybody's AI-and-rockets piggy bank has enough room before it makes the couch cushions explode. These companies need staggering amounts of money, investors want staggering returns, and somewhere a spreadsheet just whispered, “please don't make me be responsible for civilization.” That's your daily byte. Have a great day. Until next time.
