Terms working their way into my lexicon since starting at @PalantirTech: "echelon", "situational awareness", "saved rounds", "throw new SafeIllegalArgumentException()"

Today I wrapped up teaching an AI course for older adults at the @OsherLifelong Institute at @UW. Fantastic experience. One of the students even made me chocolate chip cookies. That never happened at Harvard.

I asked ChatGPT to generate an image of what it thinks I look like, based on all of our previous chats, including information about my interests and hobbies. I think it pretty much nailed it.

I haven't written significant Java code in more than 25 years, but thanks to ChatGPT it's all coming back to me now ... like riding a bicycle with fifteen extra pedals and no seat

Just to be clear: I have nothing to do with @MattWalshBlog. (@timesofindia ran a story apparently confusing me with him.)

Today we're releasing Ultravox v0.5, the next iteration of our open-weight speech language model
With this release, we've closed the gap with proprietary models. Ultravox now outperforms GPT-4o Realtime & Gemini 1.5 Flash on key benchmarks for speech understanding

In an effort to avoid spending $350 to replace an e-ink tablet with a broken USB port, I have successfully spent $400 on equipment and materials to repair it myself. #winning

Use of AI tools like @cursor_ai is spoiling me. I now expect to be able to just hit <tab> in any window and have everything autocomplete. <tab><tab><tab><tab>

I HAVE FORGOTTEN HOW TO MAKE TABLES IN LATEX. I am pretty sure this means I forfeit my PhD.

Like the rest of the Artificial Intelligentsia, I have switched to @cursor_ai as my IDE of choice. So much more powerful than Copilot! Not sure I can write code without an LLM behind the scenes anymore.

Today I commit to do some good in the world. Be a light in the darkness. To be there for my children, and give them something to dream for. No election can take that away from me. Easy mode is over: now I have to work to make the world a better place.
