lawrenceduk··on Security Disclosure
You open a SaaS shop where people come to use it
lawrenceduk··on The largest electric aircraft just flew [video]
There will still be some noise. But yes, it’ll be less noisy.
lawrenceduk··on Destroying My Homelab with Kubernetes – Linux Society UNSW 2026 [video]
Nice intro to Kubernetes talk. Not sure the title’s accurate though, you didn’t seem to destroy anything.
lawrenceduk··on My AI-built PHP engine in Rust passes 17% of PHP-src tests, renders WordPress
Is it astonishing you got to 17% with some vibe code? Sure.

But most of the stuff I’ve vibe coded this year has been astonishing by 2025’s standards.

If you got 100% I’d be genuinely blown away.

lawrenceduk··on Study investigates how mass distribution of baseball bat affects performance
Clicked on the story expecting underwater bat-like weapon system. Was incredibly disappointed.
lawrenceduk··on Efficient method to capture carbon dioxide from the atmosphere
We monitor air data quite closely at work.

CO2 rises really fast with people in even a large space.

I wouldn’t put too much effort into vents above a door as we’ve seen that CO2 will leak through doors and even floors/ceilings very quickly.

lawrenceduk··on X-59 3D Printing
Got briefly excited thinking they’d actually 3D printed the real thing
lawrenceduk··on How to Run WordPress completely from RAM
Yeah I skimmed it and it all read like when I ask ChatGPT to go wild and be “fun”.
lawrenceduk··on Solar power has begun to transform the world’s energy system
We usually drive to work. That means that when the sun’s shining, the car isn’t home.

Conversely, if we didn’t drive to work, we probably wouldn’t have a car.

On the other hand, we have a big solar array at work so if we had on-site parking (we don’t) we could drive our power home.

It’s probably impractical in reality though, the tax treatment would be chaos and we use the power we generate at work during the day on-site.

lawrenceduk··on Electric Propulsion's Dirty Secret: Why Lithium Can't Fly (Or Float) Profitably
Pilot here, I don’t think this is right.

Aircraft typically operate at 80-100% power output. It’s not the average 20% power output of your car.

Weight is pretty much everything, the savings from regenerative braking in an aircraft are almost 0% but the cost of enabling it is some tons.

This tech makes loads of sense in a car but I’ve never flown an aeroplane in stop-start traffic because that’s not how the sky works.

lawrenceduk··on Planes are having their GPS hacked. Could new clocks keep them safe?
It’s because they’re next to Kaliningrad, that weird Russian exclave
lawrenceduk··on WebSockets cost us $1M on our AWS bill
It’s ok, it’s now a million dollars/year cheaper when your renewal comes up!

Jokes aside though, some good performance sleuthing there.

lawrenceduk··on Shedding light on alcohol's long shadow
Are you sure you’re not just flying more now you’re not drinking?

Single pilot IFR being fun or scary mostly comes down to currency!

lawrenceduk··on Show HN: Safe Routes. real time turbulence data, ML predictions with an iPad
Mostly mountain wave presumably?
lawrenceduk··on Montessori Education
Went to Steiner school, can confirm I’m capable of knitting a chicken.

It worked out well for me in terms of education but that’s a small data point.

lawrenceduk··on VATSIM: The International Online Aviation Network
VATSIM’s pretty neat, really enjoyed flying in sim using it before I got my actual license.

I’m not sure how much it helped though, the real challenge (at first) is making your brain handle “fly the aeroplane” and “talk to people” at the same time.

lawrenceduk··on Can Microsoft Flight Simulator help me learn to fly or make me a better pilot?
Weirdly often not! They’re quite different recreational activities.

Flying powered is a “go to the airfield and takeoff” whereas gliding is more of an all-day team sport at most clubs as there’s a lot of ground handling required for towing, winches etc.

lawrenceduk··on Active turbulence cancellation makes bumpy flights smoother
I think this would effectively increase the stresses on the airframe leading to greater metal fatigue which probably isn’t a good outcome
lawrenceduk··on DIY-Thermocam: A low-cost thermal imager based on the FLIR Lepton sensor
I think the company originally made forward looking infrared sensors for military aircraft.

The name’s just stuck around since.

lawrenceduk··on The Maintenance Race
Just so happen to be in La Rochelle tomorrow. I’ll go find Joshua!
lawrenceduk··on ESP32-C5: Espressif’s First Dual-Band Wi-Fi 6 MCU
We have 10s of thousands of street lights using LoRaWAN amongst other things.

It’s very much being used! Just might not be that obvious.

lawrenceduk··on Toit – A Language Designed for Microcontrollers
I looked at this the other day! Sadly no way to configure WiFi other than at the point of flashing the device which rules it out for a lot of use cases.
lawrenceduk··on The wrong way to switch operating systems on your server
This is a bit dumb and I feel like if as much effort had been made doing it as writing the blog post, a more positive outcome would have resulted.
lawrenceduk··on What happens after a bank closes all of your credit cards?
Surely the drop in credit score is attributed to opening a load of accounts in a short space of time - it's something that people generally do when they're desperate for credit so is used as an indicator.
lawrenceduk··on Drivers locked out of their cars at Royston Tesco
Last time this happened in the UK it was a push to call for assistance system that got stuck on, also at 433mhz. It’ll be the same here.
lawrenceduk··on Response to “WireGuard: great protocol, but skip the Mac app”
Our team really likes the mac app!
lawrenceduk··on Thrust Vectoring at Model Scale
Really enjoyed the video showing the spectacular failures in the build up to getting it right.

Turns out rocket science is hard.

lawrenceduk··on Show HN: iOS14 weather (METAR) widgets for pilots
Just to be a pain... as an instrument-rated pilot could the widget have the cloud heights on it visually? Maybe the top of the widget is 5,000 feet or something.
lawrenceduk··on Show HN: iOS14 weather (METAR) widgets for pilots
Nice! Bought it. Cool!
lawrenceduk··on Show HN: Deploy to K8s without YAML using ShuttleOps
I think we run about $100,000/year of this in production. Ouch.
