The girls skipping should have feet on the ground at that point

The bicycle front wheel isnt between the fork blades

Isn't this a telling aspiration? To want robots to look after your kids, so you can do stuff, rather than robots to do stuff, so you can spend time with your kids?

The darkness inside these shrivelled men must be like a gaping unfillable void.

NOW - Musk: "My prediction is there'll be more robots than people... everyone on Earth is going to have one and going to want one... who wouldn't want a robot to... watch over your kids, take care of your pets... we are in the most interesting time in history."

But that is my professional understanding of how IR heating works efficiently - by heating the occupant directly when required and not being left in continuously, which is going to cost more than virtually any alternative.

That makes good sense - do the standard EPCs give you enough information to work out import/export/onsite use, or is that something you add?

Alan Clarke @alanclarke.bsky.social · 6d

So probably used a default-for-age cavity wall in the model - if you actually have solid wall then possibly the survey was at fault

I've just looked at EPC of a newbuild some relatives just bought - actually not bad at all on fabric, I think about 45 kWh/m2.a in PHPP, with gas combi - EPC 84, a solid B

With passivhaus designs we've usually got a B (provided MVHR is on the "list") - need PV to reach A

Alan Clarke @alanclarke.bsky.social · 6d

Does that include PV?

How much #AirPollution is created when you burn wood?

👉 Defra approved/#Ecodesign stove = 400 times more polluting than a gas boiler.
👉 Open fire = 4000 times more polluting than a gas boiler.

Please think twice about burning if you don't need to.
#WoodBurning

A visualisation of lungs, showing that a wood stove can be 450 times more polluting than a gas boiler.

What have you replaced dropbox with?
And how do you deal with project collaboraters who still use it?

I dont know - there are clearly some efficiencies for users of a more or less universal interface and common file format

Web browsers might be first place for this but I understand firefox has v small user base (2.5%) - Chrome has majority, presume cos included in android

I think there is actually a separate version but I havent tried yet, and will be a pain to convert existing files between two formats all the time

Just for the record, and it’s insane that the mad king made me look this up, there is documentation of the US giving up all claim to Greenland to Denmark when we bought the Virgin Islands from them in 1916.

history.state.gov/historicaldo...

DECLARATION
In proceeding this day to the signature of the Convention respecting the cession of the Danish West-Indian Islands to the United States of America, the undersigned Secretary of State of the United States of America, duly authorized by his Government, has the honor to declare that the Government of the United States of America will not object to the Danish Government extending their political and economic interests to the whole of Greenland.

You might find it needs 4g

Last week gloucester to edinburgh and back (west coast line closed) - just glad they weren't crowded as I'm too big to fit in a single seat for that long

I worked in projects with OMA when I was at Arup (karlsruhe museum and eurolille). My memory is they were quite annoying, and liked to send thick-lined sketches by fax

Alan Clarke @alanclarke.bsky.social · 15d

Feels like grok CSAM might be a bit of a test case of how much illegality you can blame on the machine - and Hesgeth is looking interested as his idea of military attacks turns out to basically be murder

Alan Clarke @alanclarke.bsky.social · 15d

So the "wells" in the name is just marketing hype then?

They weren't all people either - I don't know that Honey here has closed her account but she doesnt tweet anymore

Easiest ventilation to fit is continuous extract - can be single fan per wet room - or ducted to one fan.

This will ensure sufficient ventilation however airtight the house is. There's sonetimes an assumption this is just for medium tight houses but is good for any feasible level of retrofit seaing

It took us too long to realise when Musk called that cave rescuer a "pedo guy" he meant it as a compliment.

Subtle age bracket there - you cant be old enough to have watched jim'll fix it or rolf harris every week, but old enough to know about their offenses and that they had been on telly
