I was in a project handoff with developers recently and learned how much AI has changed software development. I’ve only scratched the surface. A few takeaways: 1. Claude managed tasks through GitHub Issues 2. The repo included docs and skills for Claude 3. AWS was completely configured with code

Fun project lately: stood up LibreChat and Open WebUI for testing, both hooked up to multiple models via AWS Bedrock plus a smaller model running on a GPU node in our HPC cluster. Exploring what private, self-hosted AI chat could look like for a research org. #SelfHosted #AI

Just when I was starting to like Claude… Back to the memory cut off era, but worse. 🤣 “I should clarify—as of April 2026, the current iOS version is iOS 18. There isn’t an iOS 26 yet (Apple’s versioning goes sequentially, so iOS 19 would come next).”

I usually get excited about new Apple software releases, but *OS26 released yesterday are a huge disappointment. The Liquid Glass design elements look like Windows Vista and detract from the simple user interface.

I thought that I understood the basics of generative AI, but I'm pretty sure that there's some magic going on... and maybe some randomness too.

When I studied in Australia, we spent a week at a research station on Heron Island. The island was very small (1/2 mile long and 1/5 mile wide) and had a resort on the other side. One side observed daylight savings time and the other didn’t. Literally a 10 minute walk set you back/ahead an hour.

I usually don’t have a problem with daylight savings time, but my brain can’t quite come to terms with it yet this year.

Yikes! I’d imaging there are quite a few (smaller?) orgs who have let their VMware support expire because of the increased prices but haven’t migrated off of it yet. Hopefully the patch will be widely available when it comes out 🤞

When you write an email in a rush, you are valuing your time over other's. When you put thought into the formatting, clarity, and conciseness, you are valuing their time. The more people on the email = the more time there is to potentially waste = the more time you should spend on it.

I’m always amazed how much work I can get done at night when Slack, email, and phone are all quiet. Synchronous communication can be so distracting. Productive, but distracting.

I've been getting a few of these PayPal phishing emails every day. Can't block them because they actually come from paypal.com. Is anyone else getting slammed with this attack? If you call the phone number, they will almost certainly request your credit card number or access to your computer.

Open AI steals the entire internet, but is upset that DeepSeek stole from it. Makes about as much sense as anything else going on these days.

Breaking news: The White House budget office on Wednesday rescinded an order freezing federal grants, according to a copy of a new memo obtained by The Post, after the administration’s move to halt spending earlier this week provoked a backlash.

I don't see how NVIDIA won't bounce back. Innovation isn't bad and I don't see an AI future that doesn't run on NVIDIA chips. If someone created a better GPU, that would be another story.

New note strategy: Keep one overview "project" note and link related meeting notes. The overview note has current action items, holdups and other current information. Nothing stale. Meeting notes provide a historical record project note provides a snapshot of the current state. Thoughts?
