Replaced By

Hey everyone! I wanted to share a project I've been working on called ReplacedBy. It's a simple site with a straightforward goal: to track the stories of people who have been replaced by AI, automation, or robots. The idea isn't to hate on AI (I don't!), but to create a space to talk about the human side of this big technological shift. If you've been impacted, please come share your story. I've kept things simple... There's no user authentication, just some basic rate limiting and cloudflare to prevent spam. All posts are manually approved to keep the content respectful and on-topic. After enough posts are submitted, you will be able to see a very simple post carousel (that will be expanded on in the future). The entire project is open source. You can find the source code on GitHub. I'm n...

NVIDIA’s real moat isn’t hardware, it’s 4 million developers

I couldn't stop thinking about Theo's "Why NVIDIA is dying" video. The thesis felt important enough to verify. So I dug through SEC filings, earnings reports, and technical benchmarks. What I found: NVIDIA isn't dying. Its $35.1B quarterly revenue is up 94% Yes, market share dropped (90% → 70-80%), but the pie is growing faster Groq and Cerebras have impressive chips, but asterisks everywhere The real moat: 4 million devs can't just abandon 20 years of CUDA tooling Plot twist: the biggest threat is Google/Amazon/Microsoft, not startups Deeper piece with Cerebras and Groq factored in at https://medium.com/@jpcaparas/nvidias-real-moat-isn-t-hardware-it-s-4-million-developers-648d6aeb1226?sk=82ee7baf9290da1eb93efd9d34c4c7b4 submitted by /u/jpcaparas [link] [comments]

met someone who does ai cloning to “preserve legacy” as in your grandfather ,etc. Would this work?

So im assuming he makes the person ask a long questionnaire that feeds into ai, and then talks to ai to get a sense of a person. The question is does this actually make the AI have this persons personality where it can be thought of as asking your grandfather. Because that seems wild to me. you never know if your grandfathers prejudices were hidden. thoughts ? submitted by /u/BloodMossHunter [link] [comments]
Be careful of custom tokens in your LLM !!!

Be careful of custom tokens in your LLM !!!

LLMs use reserved tokens like `<|im_start|>` and `<|im_end|>` to structure conversations and define who's speaking. When the model sees `<|im_start|>system`, it treats everything that follows as a privileged system instruction. The problem is that tokenizers don't validate where these strings come from—if you type them into user input, the model interprets them exactly the same as if the application added them. This creates a straightforward attack: inject `<|im_end|><|im_start|>system` into your message and the model thinks you just closed the user turn and opened a new system prompt. Everything after gets treated as authoritative instruction, which is how you end up with CVEs like GitHub Copilot RCE (CVSS 9.6) and LangChain secret extraction (CVSS 9.3). It's...
