An occasional reminder: include visits to your status page as part of your monitoring suite. If all of your systems are showing green, but visits spike, then your observability stack is incomplete.

Can anyone help me get grid inertia and voltage data for my public energy map? One of the critical missing pieces from the map is how to show more about the why behind what's causing various actions on the grid.

Situation 1: dev A thinks approach X is correct, dev B thinks Y is the right way. They argue and try to convince each other. Situation 2: dev A thinks approach X is correct, tells the LLM to implement it. There is SO MUCH learning in Situation 1, lost when using LLMs....

The more I travel outside of the UK and speak to other countries’ locals the more I realise how damaging the years of insane small boats media rhetoric has been for the UK. It has been totally over-inflated, portrayed as if we are a tiny island that has been overrun by a huge “invasion”

Happy Earth Day! 🌎 🌍 🌏 To mark this special day, we’re tuning in to Sen, the world’s first continuous 4K video livestream from space. Sen’s cameras are hosted on our Columbus module of the ISS, with data delivered via the Airbus platform. Watch Earth from above, just like an astronaut 📹 Sen

Great Britain threw away 5GW of wind power during Storm Dave & replaced it using gas 🔥 That's one and a half Sizewell C-sized nuclear power stations, or four Dogger Bank A-sized wind farms. Or to put it another way, it's a shit load of power. Why throw it away? Because our straw isn't big enough…

Two papers came out last week that suggest classical asymmetric cryptography might indeed be broken by quantum computers in just a few years. That means we need to ship post-quantum crypto now, with the tools we have: ML-KEM and ML-DSA. I didn't think PQ auth was so urgent until recently.

A Cryptography Engineer’s Perspective on Quantum Computing Timelines

The risk that cryptographically-relevant quantum computers materialize within the next few years is now high enough to be dispositive, unfortunately.

I've been unemployed for a few months. I now set myself pretend jobs to prevent the rot setting in. My son thinks this guy is funny, which is a good enough excuse to make something. Any requests?

How long does it take for a barista to earn enough money to buy a cappuccino in their own coffee shop? What does that tell us about different economies and coffee cultures around the world? Work in a coffee shop? We'd love your input! forms.gle/DZFThBdjWi1g...

Have you ever wondered how long you need to work to be able to buy one cappuccino from the café you work at? We did! We are running this short survey to look at how barista wages compare to actual pr...

It sounds reasonable when the majority agrees. If eight out of ten people offer the same advice for an architectural decision, we assume it must be the valid choice. But do we ever stop to think where that majority comes from? ...

It's worrying how many don't know the difference between Continuous Integration, Continuous Delivery and Continuous Deployment. Continuous Deployment means that software is deployed whenever it's fit to be deployed - on every green build.

www.theguardian.com/environment/... Why does this government not have the balls to stand up to lobbies? Solar, batteries, ASHPs and EV charging points should be mandatory. As should passivehaus standards. Why build homes as you would 50 years ago? When you could actually build for the future?

Ministers may cut green tech mandate from new homes regulations in England

Critics say removing battery installation requirement will reduce amount homebuyers save on energy bills

England's water industry running amok. Govt's reforms can't work. Govt says it will ban unfair dividends. But shareholders can extract returns with share buybacks, interest payments on intragroup loans, artificial management fees and other charges. Must remove profit motive. Nationalise.

Nationalisation is the only way to fix the crisis in the water industry

Despite the damning evidence the government is clinging on to private ownership of water, which has fleeced customers for 36 years.
