Such a great, intuitive intro to neural networks

I'm having too much fun with LLMs mattsayar.com/llms-arent-j...

@ashley.dev is your website down?

So NOT SentinelOne as previously rumored. PAM instead of Endpoint. Interesting

Tri-tip used to be a great value, but that's not true so much anymore. I recently bought four lbs of pork tenderloin for a grand total of $12 and half of it fed my whole family with leftovers. Highly recommend this recipe www.menshealth.com/nutrition/a6...

Since SendGrid is getting rid of their free tier, I had switch my newsletter service on my Raspberry Pi over to Brevo mattsayar.com/sayonara-sen...

Ha! Someone sent me this comic of mine from about 15 years ago, predicting the TRUE THEORY OF VIBECODING www.smbc-comics.com?id=2362

This feels about right

This is SUCH a plausible scam. I expect to see more of these. Big giveaway for me is the bit.ly address instead of a.co. Also, nothing in my email or Amazon app. Even after all that I still wonder if I'm leaving money on the table. It's good!

Anybody have any ideas for how to use an AI agent to automate building apps locally? Trying to automate this process: You follow a project's build instructions, get errors every step, Google/GPT the error msgs, update/switch versions of tools and packages, slowly chip away until it finally builds

I just used Claude Code in VSCode to polish off a project that I started with chat-based coding a while ago. I gave up on it because it took too much work to copy/paste/troubleshoot/repeat. But with Claude in the terminal, it took five to ten minutes to finish. Would've taken a couple hours before

Seeing it announced as GA on stage and then seeing it in my actual local environment minutes later is pretty slick. gg @anthropic.com

Tried out the new GitHub agentic coding agent from Claude. The results were mixed https://mattsayar.com/personalized-software-really-is-coming-but-not-today-maybe-tomorrow/

@simonwillison.net Another thing about AI energy usage is that if a user is completing projects 10x faster, then isn't their overall energy expenditure lower? That's less time spent microwaving lunches, driving to and from work, borrowing coworkers' energy, using other energy-intensive resources etc

My Subaru Outback has all the hardware necessary for High Beam Assist but it's software locked.. Used ChatGPT Deep Research to research and confirm, but fixing it still needs an unholy combination of a custom ODBII cable + ancient software. Oh well, I'll just keep doing it manually like a chump
