It was so much fun deep diving on AWS Lambda durable functions with @embano1.mgasch.com at this year's re:Invent! And now we are doing it again and YOU get to ask questions! Join us tomorrow for "Serverless Office Hours | AWS Lambda durable functions". Watch us at twitch.tv/aws at 11 AM Pacific.

Wow! 3k views in just one day - couldn’t be more happy with @edjgeek.bsky.social and my first deep dive on AWS Lambda durable functions at #reinvent2025 youtu.be/XJ80NBOwsow?...

the cdk release containing the support for durable functions was out yesterday! github.com/aws/aws-cdk/... now I go and do what Werner is always telling us to do: go build 😁

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

It’s unbelievable how much of an impact LLMs have on my daily work. I‘m definitely 10x more productive and the quality of my work also improved as these tools help me to reduce my deficiencies. Nope, they don’t replace thinking (yet), but all the undifferentiated things which slow down productivity.

We may still get a generified version of errors.As in #golang's standard library! 🤞 github.com/golang/go/is...

Use TouchID for sudo on macOS: - cd /etc/pam.d && cp sudo_local.template sudo_local - uncomment the line in sudo_local

Nice, more management events. In EventBridge (receiving CloudTrail events), we call those non-mutating events which customers and partners use to subscribe, filter and quickly take action. Common use cases (obviously) threat detection (S3 bucket scans anyone?) and identifying noisy polling code.

I think *most* errors should default to returning a "safe" error message that doesn't include any raw input data or sensitive data about the host system, and then add an optional field/method that has more detailed info that might be sensitive (likely only used during debugging).

arXiv Daily: We have a chat service that works over DNS so you can LLM on a flight without paying And of course it works 😆

💯 Best conference 🎤🫳

Lots of cool innovation happening in the area of logs(tructured systems) #LazyLog #SpecLog #SD25

Fantastic insight by @hillelwayne.com #SD25

Only at #SD25 Just.BRILLIANT!

Every day, we wake up with horrible news what humans are capable of doing. So, it’s easy to miss the MIND BENDING research, understanding the fundamentals of our universe, and the innovation coming out of this for society. Thank you, Thea. MUST WATCH talk #SD25

Three talks in, and the key theme this year seems to be „Simplicity“ (reminds me of @werner.social‘s last re:Invent talk about #Simplexity) Couldn’t agree more 👍 #SD25

As always, highly inspirational and insightful talk by @dominiktornow.bsky.social And thx for including and calling out one of my favorite papers 🙏 His presentation skills are TED talk level 🤯

And a proof to myself that I made it here…finally, after 2y of struggle to attend…still feels surreal 🙏 #SystemsDistributed Finally meeting the legends @joran.tigerbeetle.com @dominiktornow.bsky.social and the amazing Tigerbeetle crew!

The attention to detail and love the crew puts into this conference is next level. Already my favorite conference! Let’s go #TigerStyle 🚀🚀🚀

En route to Amsterdam #SystemsDistributed25 Third attempt to attend, this time it will happen 😁 @joran.tigerbeetle.com

You know my answer 😁

I've set this up once with Terraform to get notifications about changes in my AWS organization's core structure, e.g. updating SCPs or adding/removing member accounts. Really helps me sleep a lot better 🥱

LOL, after the great success of Anna Concurrenina, the director of Jepsen is back with another hit for the whole family 😆 Should be fun (as always)

Two awesome new feature for AWS automation today! 1⃣ All AWS API definitions are now publicly available on GitHub (aws-news.com/article/2025...) and 2⃣ Invoice summaries can now be programmatically retrieved (aws-news.com/article/2025...).

Three Trail of Bits engineers audited core Go cryptography for a month and found only one low-sev security issue... in unsupported Go+BoringCrypto! 🍾 Years of efforts on testing, limiting complexity, safe APIs, and readability have paid off! ✨ Yes I am taking a victory lap. No I am not sorry. 🏆

Yeah! This paper also cites a bunch of classic papers. The original SIGMOD publication: ipads.se.sjtu.edu.cn/_media/publi...
