Yep. It has been the right approach ever since the feature was released to GitHub Actions ... over 4 years ago: github.blog/security/sup... 😳 Either time is running faster when you're getting older or our industry is slow to adapt the better habits

finnish verb kiroilla /ˈkiroi̯lːɑˣ/ can mean using kiro, but more literally it means cursing or swearing 😁

@lucvandonkersgoed.com does this happen often — something is published in the feed, but the actual blog post cannot be found?

the @kiro.dev CLI I run on the CloudShell can resume the chat but it feels a bit unnecessary...

Niko Virtala @nikovirtala.io · 03/01/2026

AWS CloudShell documentation says: "if you don't interact with it using your keyboard or pointer for 20–30 minutes, your shell session ends" — a perfectly reasonable timeout. When accessing CloudShell via AWS Console iOS app the shell timeouts much faster, like being away from app a minute or so 😫

true. ai is incredibly bad at delivering truly simple things

My concept of humanity says people can not be replaced. It doesn't work that way, but as always I'm looking forward to what happens next. Who, what and how will they fill this void?

It feels sad, even today. There are not too many speakers who can catch your attention and create a sense of connection the way Werner does — he is talking to me, about me 😳

Niko Virtala @nikovirtala.io · 11/12/2025

The invitation already said this would be special and it certainly was — it was the last re:Invent keynote we would see from him. Two more words, he said: "Werner out!"

Niko Virtala @nikovirtala.io · 11/12/2025

Ever since I started working on AWS stuff 2017, I haven't missed a @wernervogels.bsky.social #reInvent keynote. Not this year either, even though the schedule was horrible — the keynote started at 1.30 am local time

Niko Virtala @nikovirtala.io · 09/12/2025

not bad. that is 94 kilometers / active day — is that a lot or little, I guess, it depends 😁 and there are still 22 days left in the year, you never know how far one can go

accurate! I need to remember to show some gratitude to our internal AWS platform team, who are managing all the savings plan sorcery centrally on our behalf 🥰

don't know who designed this feature, but at least it is not really personalized to **me** 🫠 my **easy** endurance ride is normally 2 hours 😅 today I rided 4+ hours and even that wasn't especially "hard": strava.app.link/3oDXkYMWSYb

once you get into this state, apparently, you need to reload the window to get kiro healed — waiting alone does not seem to be enough

000

Niko Virtala @nikovirtala.io · 06/12/2025

when you break the @kiro.dev request quota, it still tries to generate "something" 😁 this was not intentional — just too many open IDEs open at the same time

Niko Virtala @nikovirtala.io · 05/12/2025

due the merging strategy the repository uses, one should use conventional commit syntax on merge request title. this seems to be a) something it couldn't figure out b) something it cannot change

Niko Virtala @nikovirtala.io · 05/12/2025

I gave @kiro.dev autonomous agent a little maintenance task some hours ago and left it alone ... now it is almost ready 🙌 I perhaps would have get done it myself faster and with fewer mistakes — look at the commit history of this pull request 😄 github.com/nikovirtala/... #reInvent

Metaprogramming. I think I've always been, for a long time without even realizing it, interested in programming the programming. Perhaps even more than the programming in the traditional sense. Which is why all these AI thingies feel kinda easy and natural — it is not that much different 🤷‍♂️

He is the only one of the AWS keynote speakers who is genuinely inspiring and truly puts his person into the game — one can only admire 🫡

It is gonna be a long day today. Werner is having his #reInvent keynote this time in the afternoon 3.30 pm PST which translates to 1.30 am EET 😴 It's been my habit to watch it ever since I've been working with AWS stuff and I simply can’t let the poor schedule break the streak 😁

I learned very early this morning that Amazon #DynamoDB Streams capacity is not really unlimited and that after consuming it at 450 RPS you will be called a noisy neighbour 😅 Challenge unlocked?

nope. I just bought UAD Showtime '64 from their black friday sale, just to get disappointed a big time. the real deal, my handwired Princeton Reverb is still a light year ahead of this model

@kiro.dev got powers! this sounds actually very nice and practical way to share your knowledge to both the AI agents as well as to your colleagues using those agents — time to reveal some secrets I guess? 😁 kiro.dev/blog/introdu... #reInvent

My gut feeling just told me we'll be using the new #Lambda durable functions a lot in near future — very nice release! 👏 But not perfect, where is my day one #awscdk support? 😁 docs.aws.amazon.com/lambda/lates... #reInvent

where is all the #reInvent buzz, if not here?

Niko Virtala @nikovirtala.io · 01/12/2025

yeah, the blog indeed says it has been done with specialized hardware in mind, but not mentioning GPUs — I would find it a little weird if it doesn't eventually mean also those. it may also mean "lambda anywhere", which would be something

Item-level access control for #DynamoDB — it is my long time wish from @awscloud.bsky.social do you think we will get it this year? #reInvent

if I don't tell, or use it without customizations, nobody can say if it was me or LLM — it is pretty easy to put LLM to produce things with your style

with modern in this case I mean usage of ecmascript (es) modules

Niko Virtala @nikovirtala.io · 26/11/2025

and why we've been waiting for so long? well, it has been all or nothing situation due to some choises: modern javascript (typescript) hasn't been really supported until lately

Niko Virtala @nikovirtala.io · 26/11/2025

dunno who should hear this but the @awscloud.bsky.social cloudwatch application signals provides pretty good level of observability to your systems straight out of the box and only using the auto instrumentation — surprisingly easy way to get started with opentelemetry! 👏
