Many people don’t realize if you leave an agentic session idle for over 5 minutes or 1 hour, you pay significantly higher token costs unnecessarily. The cached tokens in the context become uncached. Cache rewrites are more expensive. You may have compaction too.

I know some people aren’t sold on it, but I have been using Fabel 5 at work and I am extremely impressed with its ability to work for extended periods of time and produce a high-quality PR. It seems to excel on repos with extensive tests (e2e, integration, unit).

If you use coding agents regularly, it helps to know what they're actually doing. Datadog Lapdog is a free way to see under the hood: cost, context window usage, and tool use. In this post, I share why you might want to take a look at this tool. chrisebert.net/see-what-you...

There’s a large cemetery directly across from my work that has an annual tulip photo contest. It always seems so strange to me.

Recordings from the Code with Claude Conference are now available. I put together a guide to the sessions worth your time, the workshop repos on GitHub, and the articles I found most useful from the conference floor here: chrisebert.net/code-with-cl...

I attended Anthropic's Code with Claude developer conference in San Francisco on May 6th. In this post, I share my key learnings and how I see the role of software engineering evolving. chrisebert.net/notes-from-c...

Wow, my daughter gave me six cards this morning

Ugh. I am going to the Code with Claude Conference in person this Wednesday. I am having difficulty determining which sessions to prioritize.

Does anyone have ideas for AI activities for children at take your child to work day? This was assigned to me as a session tomorrow and I haven’t had time to prep!

I may have ordered a bit too much sushi for dinner

I have never seen a hotel room with fitness equipment in it before

I think I’m going to start claiming the features I’m working on are too dangerous to ship or release and see how long I can get away with it. 🤣

Who’s going to the Code /w Claude conference in person?

It still needs a bit of polish, but my weekend project making a site track browser bloat is coming along (open to feedback) webbloattracker.com

This is a crazy read. This guy was able to create a two employee company with $1.8B in revenue selling GLP1 medications in less than two years using AI. www.nytimes.com/2026/04/02/t...

I’m making a website to track how large the initial page load is for popular sites. I have a draft (not permanent) version up now. Any feedback/ suggestions? Some sites have bot (Playwright) detection so I’ll probably skip those and replace with others.

It’s a nice day for a University of Michigan Lacrosse game

I want to get better at note taking as I have more obligations and projects than ever before. I’m torn between buying a reMarkable or iPad device for note taking and am torn between the two.

Is there a way to stop the “You may also like” suggestion on Apple Podcasts? How annoying…

Ugh I want a note taking device like Remarkable or Kindle Scribe. It’s hard to pull the trigger without trying them.

I don’t know anyone who as been asking for an agentic AI coding tool from Atlassian 😂 www.atlassian.com/blog/announc...

Did the Twit podcast network recently disable chapters in Apple Podcasts? I enjoyed that feature, but it now seems disabled in recent episodes.

This report on the potential impact of AI on employment is sobering. I am worried this won’t be good for the rustbelt. www.brookings.edu/articles/mea...

The Verizon outage yesterday was surprising to me. I use Visible, Verizon’s discount carrier, which uses the Verizon network. My phone worked the entire day without issue. www.cnn.com/2026/01/14/t...

Given Microsoft’s aggressive efforts to encourage customers to adopt Copilot and AI services, it baffles me why MS Teams lacks the ability to summarize threads and messages and only surface time sensitive notifications. This seems like something AI would be very capable of.

2026 prediction: Career fairs make a comeback. As AI floods both sides of hiring, signal gets noisier and fit is harder to judge. Face-to-face human interaction becomes the differentiator.

I received an email at work yesterday requesting that I limit my AI usage as I’ve used too much Claude Code 😅

Age Verification isn't about Kids or Censorship, It's about Surveillance

Great suggestion

I just shared my reflections from re:Invent 2025. Big themes this year: agentic AI, Rust performance wins, Arm everywhere, DSQL, and ABAC. It's always a great week of learning. chrisebert.net/another-aws-...

Amazon is aggressively promoting the Nova Act, but I find Playwright + Claude models to be quite good already. The argument is that there’s a special model Nova trained with reenforcement learning with the browser automation tool. I’d love to see an objective comparison of both approaches.

This is apparently me when I take my five-year-old daughter to the park. She was very excited to give it to me when I got back from the AWS re:Invent conference 😅

Excited to deep dive into the new product announcement for AWS Lambda Durable Functions at reInvent 2025

First AWS reinvent session of 2025!

I made it to AWS reinvent

The AWS re:Invent app seems pretty buggy this year. When I try to enable notifications, I get an error message. Their AI recommendations error out too. #reinvent

I actually have like 100-200 people visiting anthropicnews.com daily and I didn’t even do much to advertise it 😅

Instead of invading everyone’s privacy with age-verification laws, how about parents step up and do their job? This Michigan bill is ridiculous. www.mlive.com/politics/202...

I added day/night mode to AnthropicNews.com. Feel free to give me suggestions and feedback on how this could be more useful (if you're into Antropic news).

I benchmarked AWS Lambda on Arm64 vs. x86_64 across Node.js, Python, and Rust. Sharing the results for anyone making runtime/architecture decisions. chrisebert.net/comparing-aw...

I've been wanting a site/place that aggregates Anthropic-related AI news. This weekend, I created a simple Cloudflare site for this called anthropicnews.com. It's still very much a work I progress, but I thought I'd share.

Welp, I guess it's time for me to switch to AT&T Fiber or Wowway Internet. I am getting sick and tired of Comcast/Xfinity charging me for overages when I use more than 1.2TB of data. That's not that much data these days.

MCP Inspector is a free browser tool for testing and debugging MCP servers. If you're doing development with MCP servers and haven't heard of it yet, you need to give this tool a try. chrisebert.net/testing-mcp-...

I’m a nice afternoon working on a blog post at Starbucks on AWS Lambda benchmarks.

This Segment Anything 3 model Meta just freely released looks really good: ai.meta.com/sam3/

I've been working on building an AWS Lambda benchmark for Node, Python, and Rust to compare x86_64 vs ARM64 performance on actively supported AWS runtimes. I plan on blogging about it later this week after a few test runs. Here’s a link to the repo: github.com/cebert/aws-l...

Why does Bluesky have so many bots?

I will be blogging about it later this week, but it is super easy to build and ship a Rust Lambda. As of November 14th, AWS officially supports the Rust runtime, and Cargo Lambda makes it a pleasant experience. @calavera.dev did some great work on Cargo Lambda. aws.amazon.com/blogs/comput...

I'm attending LF AWS re:Invent meetup Valkey w/ House of Valkey on 12/3/2025. If you’re going to reInvent it’d be great to see you there. community.linuxfoundation.org/events/detai...

Don’t pass up alumni group meetups. I went to a U of M CSE alumni meetup in Detroit tonight and it was great to connect with folks doing so many different things and also hearing what’s new at U of M.
