Hahaaa oh no fill me in.

Guessing it’s the ironic fact (vs above) that they’re being badly pumped out at scale using these tools and that’s not exactly seen as a good thing?

Claude code and codex and such are enabling romance novels of the software world!

I’m not saying that as a bad/good thing, I’m saying it as an economics/democracy lesson.

Sure LLM coding enables β€œtrashy” code that wasn’t previously economical, but mostly it just makes it cheap to produce and opens it to a new wide audience.

You didn’t have cheap mass paperbacks when books were written/copied by hand over weeks by trained experts.

I’ve worked out how I conceptualise LLM/agentic programming: a printing press moment.

It’s taken something that was previously very specialist and expensive and made it cheap.

I know I regularly joke about it being DNS.

But it sure wasn’t DMARC.

Important note about cyber security and media interaction during active incidents:

When those who know the details can’t talk, those who can talk won’t know the details.

I just spent the last two hours debugging the Bluetooth stack *in anger* because for the last few weeks I've had to re-pair my mouse with my laptop. Every time. Remove mouse, re-pair.

Turns out I had two identical mice in my backpack and I've been switching between them.

It was me.

I’m floating around kawaiicon. If you’re looking for me sometimes I’m the bright yellow person.

You’ll see what I mean in the sea of hackerblack.

Photo of a missing slice of cheesecake that looks like a cheesecake hull floating in a deep blue ocean. The "ocean" is actually the blueberry topping on the large cheesecake that we don't see completely.

All I saw was cheesecake boat and ocean for at least 5 minutes

A gov.uk webpage screenshot saying:

HOW TO SAVE WATER AT HOME
β€’ Install a rain butt to collect rainwater to use in the garden.
β€’ Fix a leaking toilet - leaky loos can waste
200-400 litres a day.
β€’ Use water from the kitchen to water your plants.
β€’ Avoid watering your lawn - brown grass will grow back healthy.
β€’ Turn off the taps when brushing teeth or shaving.
β€’ Take shorter showers.
β€’ Delete old emails and pictures as data centres require vast amounts of water to cool their systems.

πŸ‘† Another post that probably isn’t about what you think it is.

But if you thought it was then it could have been… so think about that carefully.

Science and tech/AI aren’t magic. You cant go making unsubstantiated claims and expect them to be accepted because β€œAdvances in [science/tech/AI] will save us”.

They might, they might not - but just blindly trusting or giving assurances is called something else entirely.

Figure 1: Persona vectors and their applications. Top: Our automated pipeline takes as input a personality trait (e.g. β€œevil”) along with a natural-language description. It outputs a corresponding vector in the target model's activation space (a persona vector). Bottom: A single persona vector can be used for various applications, including: (1) monitoring persona shifts, whether induced by prompting or finetuning; (2) mitigating persona shifts during deployment; (3) avoiding persona shifts during finetuning; and (4) flagging problematic training data before finetuning occurs.

Wtf sort of timeline have I found myself in.

Did you know they put the phone number and email address of nz’s local government candidates online for anyone to access.

The 2022 lists are still online too.

One the one hand great transparency, but on the other hand I did not know doxxing was a requirement to stand?
