What caused the AWS outage that felt like it took down half the internet on Monday? It started with a race condition in DynamoDB's DNS propagation, which ended up setting the dynamod.us-east-1.amazonaws.com DNS to empty. A deepdive and more details: blog.pragmaticengineer.com/aws-outage-u...

I will leave typo's and semantic errows in most posts and stuff. All small rebelion against polished'ness and slob

I just found out that Finland teaches kids in kindergarten to fact check, and actively teaches children how to spot fake news. Why isn't this standard everywhere! The best time for other countries to follow suit was at the same time. The second best is now. www.helsinkitimes.fi/themes/theme...

Arrived in Brighton for #TestBash. There was no „Having a beer at a sunny beach“ left on my 2025 bingo card, what a nice surprise! 🤩🍻

President Stubb on the UN: No single state should have a veto power.If a member of the Security Council violates the UN Charter,its voting rights should be suspended.I believe that these changes at the top of the UN are necessary in order to maintain the UN's central role in international relations

One more reminder that Slack is a terrible choice for communities, and extorts even nonprofits. Even when it’s one teaching teens to code, for free. Hack Club is moving to Mattermost. They really have no choice. Just a poor taste how Slack demands $50K in a week, no real notice

Picking colors for an overview in a ppt, how about white, pink, light blue? 🏳️‍🌈Who would notice? I’m sure @the-qa-guy.bsky.social would

No one told me the hardest thing about software engineering was compartmentalizing the state of the world so you can focus.

Hey friends! I did a TEDx talk and it's now up on the TED Conferences YouTube. It's possibly the best and most important talk I've ever done. I would ask that you watch it, and please SHARE it broadly and widely. Thank you! youtu.be/dVG8W-0p6vg #AI #Tech #TED

UK government report based on internal civil service trial finds Copilot doesn’t increase productivity, and indeed makes Excel take longer and with more errors, and requires Powerpoint users to have ‘corrective action’ applied to their outputs. www.theregister.com/2025/09/04/m...

For 58€ a month I can ride on almost any public transport anywhere in Germany. Within a 15 minute walk from my house I can access 4 S Bahn lines, 3 UBahn lines, regional trains (I honestly don’t even know how many of those), 3 tram lines and at least 4 city bus lines (probably more).

May I ask you a a favour? If you have bought one of my books, and you liked it, would you consider submitting a review on Amazon? If you have feedback for me, please DM me, I am always looking to improve. https://twp.ai/9PUohM

1/ The Danish public broadcaster DR is reporting that men with close links to Donald Trump have been 'infiltrating' Greenland in support of his goal of annexing the automous island. It is said to be part of a three-part strategy involving pressure, charm and infiltration. ⬇️

Still on holiday, so this week's By People For People post is another one of my favourite things I've written that no one read the first time. If we've ever worked together before you will definitely have heard me using this metaphor though! by-people-for-people.beehiiv.com/p/come-sail-...

Japan Post just announced they will no longer deliver mail to the United States, joining Germany, Austria, Denmark, Italy, France, and Sweden.

Did you ever do a great joke when there was only one person around and think damn I wish that had a bigger audience? Anyway today I asked my wife if there was parking and she said I think there’s a lot and I said well we only need one.

If there were a single lesson I'd drill into new software engineers it'd be this: You can be technically right and politically and systemically dead wrong.

Trust Day 1/30 sharing my favorite doodles and drawings.

I need to copy the Coldwaters Law tweet before I send my account into the ether: "I've dubbed this "Coldwaters Law" after the great @lookitup.baby . Given enough published content, an expert in their field will always have their work weaponized against them by someone not realizing its origins."

They hated Sinéad O’Connor because she spoke the truth about the powerful. She refused to “play nice” for the sake of her career. The media mocked her, the industry shunned her and the public tore her apart not because she was wrong, but because she was right before anyone wanted to hear it

Quality is a conversation. If you’re not invited, start one.

Putin and Trump might think that they can do a new Yalta and divide the world, but they don't have the power to enforce it. It's a bit like trying to sell your neighbor's house.

Anyone who didn’t realize MITRE and ATT&CK were in deep trouble by this point… -_-

I’m watching a live stream

Genuine question: is our reliance on these corporations - our institutional reliance in particular - really necessary? Why do I have to use Microsoft products (Outlook, Office)? Are there really no options for providing these basic services? The way we are dependent on these companies is disturbing.

Since exhaustive testing is impossible what does testing everything in the system actually mean in practice? Does it refer to verifying all functionalities, UI elements, buttons, or does it mean covering every possible user scenario?

"So from an executive perspective, lighting comically large piles of money on fire trying to teach graphics cards how to read is, surprisingly, the logical play. The rest, well, that’s all just creative marketing." -- Marcus Hutchins #AI malwaretech.com/2025/08/ever...

This is basically what I do for most talks. Technical title, few buzzwords, leaning into the techbro vibe, all of that Then I show up in a ballgown and talk about social skills and leading people with empathy and humanity Because yes, that’s also technical skills, and tech can be feminine too 💅

Monthly reminder: Many people have a book in them, but it takes a special kind of freak to leave the Land of Laziness, cross the Plains of Procrastination and Insecurity Mountain, find the Blade of No One Made You Do This, and use it to cut your chest open and yank that book out.

Have been watching @ministryoftesting.com's Leading With Quality convos too. @jennydoesthings.bsky.social's energy is contagious! And her push for QA leadership community really stuck with me.

I have another post about Substack that's gone semi-viral on LinkedIn and like HALF of the comments are people who had NO IDEA Substack was bad. Clearly we need to restate the facts more often

we’ve all worked on this codebase

they breached that tea app already and everyone's uploaded and verified IDs are getting posted all over the place. already seen a map logging addresses of users. please don't send your information to meme apps. might as well be honeypots for all the security they're gonna employ

In parenting, management, friendship, and relationships, people say “just showing up is the biggest part of it“ This is true! They also don’t mention how hard it is to consistently show up for everything.

I've been in the cycle where I set up everything to get me instant updates of the state of the world and my corporate life. And it fucking destroyed my mind. This is how humans function. Notifications are a cancer I've been iteratively excluding more and more.
