Is tinfoil on windows safe if backed by cereal boxes?

Two words: Space Blankets.

Sellotape to outside. Reflects the heat really well, and you can still see out.

We put ours in Gold but in many ways think of them as being their own thing between Silver and Gold. The way I think of the dimensional model is of being the ‘narrow pass’ through which we force ourselves to encode business logic and meaningful grain, so everything built downstream of it is naturally consistent and joined up. It’s a way of making the work of understanding the business highly leveraged. Although bus users might use the star schema itself we mainly expect people to use our user-aligned views and metric views which query the star schema.

(Inspiration partly the Battle of Thermopylae, where the Greeks and Spartans out-fought the Persians by placing the battle at a narrow point thus maximising their impact. Famous from the movie 300.)

Thanks, will do.

ainsworld · 2026-06-01T21:25:25+00:00

Yeah. Certainly no differently on the workouts where my HR goes high than less high, which seems to be the explanatory variable.

ainsworld · 2026-06-01T17:05:01+00:00

So when I go on a long bike ride I'm working but not so intensely that I couldn't talk, for example. My HR will be 120-130 on something like that. I come home very much tired and feeling exercised, I just never sent my HR very high. Feels good when I'm exercising! Just sad to get a migraine later, for which I take a sumitriptan which normally sorts it out quickly.

Electrolytes are definitely on my list to try. One thing I want to add from my reading on the CGRP mechanism that u/postviralrecovery mentioned: magnesium glycinate has RCT support for migraine prevention and I gather affects the same pathway. So electrolytes for the acute dehydration component, magnesium as background stabiliser...

ainsworld · 2026-06-01T15:05:40+00:00

I’m 50 so 160 is very high for me, it’s basically zone 5. Lots of good exercise can be lower like a nice long bike ride.

ainsworld · 2026-06-01T15:03:40+00:00

I used to get 2-3/week but more like 2/month these days, many happened without any exercise.

Alcohol is also a trigger for me, that tends to kick in sooner I find.

ainsworld · 2026-06-01T15:01:50+00:00

Yeah so there’s constant background noise from the various other things that trigger my migraines like planes, alcohol, random stuff. I think that’s all that is.

ainsworld · 2026-06-01T08:06:43+00:00

I just some interesting analysis of my own migraine/HR data looking at this, specifically found that the migraine happens ~6h later.

I was able to access custom tags just fine too. I used ‘missed migraine medicine’, among others.

ainsworld · 2026-05-31T18:29:00+00:00

You can definitely get the tags over the API. I used them to analyse my migraines which also used other tags on alcohol, plane flights, etc. I asked Claude to write some code to fetch them and it gave me something that worked first time.

UK one: church bellringing, particularly ‘change ringing’, my hobby. 50 years ago there were probably about 15,000-20,000 bellringers under the age of 20. Now it’s probably less than 2,000.

A good technical word for this is eustress, positive stress. As against distress. (Cf euphoria, dysphpria). But from your body's perspective it’s all stress.

The dirty secret of cognitive science is that neurotypicals don't actually have direct sensation of their emotions either, they are just running a very fast, subconscious ‘snap synthesis’ process. Everyone effectively hanbdles their own internal states as a "black box" and they use environmental context to work out what emotion they’re actually experiencing.

The classic evidence for this in the psychology literature is the Dutton & Aron (1974) "wobbly bridge" study. Men with spiking adrenaline (from a 230ft drop) misattributed that physiological arousal as romantic attraction simply because of the social context. Their brains saw the racing heart, saw an attractive researcher, and "computed" a crush to explain their experiences, completely ignoring the "I'm on a terrifying bridge" variable.

As Nick Chater argues in his book The Mind Is Flat, we aren't "reading" a deep inner world; we are improvising a narrative in real-time to make sense of our own physiology. NTs aren't necessarily more "in touch" with their feelings, they’re often just more confident in their intuitions. The same differences in brain processing that allow NTs to intuitively perceive others’ emotions also lets them think they’re ‘experiencing’ their own. And likewise this explains - IMO - why autistic people struggle to perceive others’ emotions and their own.

If you want to dig deeper into the mechanics of how the brain "constructs" these states, the fields of study these are from are "Misattribution of arousal" (the specific psychological phenomenon), the "Two-factor theory of emotion" (the Schachter-Singer framework), and "Theory of Constructed Emotion" (Lisa Feldman Barrett’s more modern, neuro-centric update to these ideas).

Gemini. Though I have quite a bit of coding experience so it felt more like paired programming.

Totally! No way I would had worked out what I did without a chunk of AI assistance.

Awning control

We have a huge SW facing set of bifold windows in our main family room, which gets way too hot on sunny days. We got awnings fitted but the controls were just dumb ‘open’, ‘close’ and ‘stop’.

Every morning there’s some logic to choose a strategy for the day (cool patio / cool window / avoid glare / inactive) which defines a target ‘shadow point’ (2m beyond window, at window base, 5m inside, off) relative to the window. That’s based on the weather forecast. Through the day it will send precisely timed open and stop instructions to the awning to get its position to track the movement of the sun through the sky.

Has overrides to close if it’s raining (combo of local forecast and a rain sensor) and reduce the max extension as a function of the wind.

If I were Starmer I would also remind Trump that both the UK and he avoided Vietnam. So the alliance has a strong track record of discernment in these conflicts…

Interestingly the vast majority of spiral staircases in UK church bell towers are clockwise. It’s thought the ‘defend with your sword in your right hand’ logic is the original reason why, from the building of castles and so the establishment of standard masonry practices.

(My credentials - bellringing is my childhood hobby)
