When a young child with type 1 is sick and not eating or is vomiting, they are getting almost no insulin. My son's basal can be as low as 0.1U an hour. It's in these cases, where he has developed high ketones with glucose level around 90 mgdl.

Have the same card solely for the rental car cover. And to be fair it works, had an issue and they refunded the full expense without too many hoops to jump through.

This is not correct. When someone with type 1 has an illness they can develop ketones while their glucose appears stable within range. This is can lead to death. About once a year, when my son is sick, we need to monitor his ketones with finger pokes. When he has a stomach bug and can't eat, we have had to go to the hospital for a drip to allow us to give insulin and lower his ketone level. Having ketones on the CGM with glucose would have been very helpful.

It's not that promotions should be given out indefinitely but I think a pay raise in line with inflation should be the minimum, unless you are under performing. It's funny when a company excitedly shares a pay raise with you are it's below inflation...

I think this only applies to certain segments of society. My child has type 1 so I'm active on Facebook groups for parents. The number of mums who say their partner is not involved really at all in their child's care is so sad. The child's own father can't supervise their child solo because they can't manage the care. And then the divorced parents. Oh boy...

Exactly. This is not paid software. We assume full responsibility for outcomes when using it. There's a reason it's not on any app store. I'm glad features like this are being experimented with. Not how I would use AI to estimate carbs...

The sandwich example is silly because you almost certainly know the fill nutiritonal info from the packaging so just use that...

iAPS is not software you pay for. This is open source software to dose insulin where you assume full responsibility for the outcomes.

This post made the rounds on the open source DIY looping community in Facebook. In my opinion this isn't a good way to use AI to estimate carbs. Using AI to estimate carbs is just one of a large list of tools at our disposal including nutritional info, company websites, weighing with a scale, etc. Just taking a photo of a food with no other input isn't going to give good results. Taking a photo, along with a description including a brand name, an idea of size, a recipe url etc will do much better. My opinions as a parent of a type 1 child

And gemini-1.5-pro is months from depreciation and there is no production alternative. 2.0 does not pass our benchmarks and in a regulated industry we need time to move to a new modek

Are you still announcing meals? I know some people use iAPS with no meal announcement which sounds amazing. We are moving our T1D son from OP5 to Loop but would consider iaps in the future. Hoping we can recreate our 92% average time in range with less work needed

I use Duet AI from Google in vscode. It is quite good at completing my code as I'm writing it. I almost exclusively write Python code. I am not promoting for a whole file or anything but it can often complete multiple lines at once

Would love to have a rule like no phones until 15 but our son has type 1 diabetes so he has had to have a phone since he was 2 and a half. I anticipate him texting us about his treatment as soon as he can write, especially during school so we are going to have to navigate appropriate use early.

This is also going to make it tricky having any rule for our younger daughter.
