Explicit variable size is useful for limited memory space envs like microcontrollers.


The kids in my family attend a school where the parents have all verbally agreed to not get their kids a smart phone until 16. This removes the peer pressure element of owning a phone/instagram/etc. When that’s removed there is little downside and huge upsides to the kids not having phones.


Can I ask what type of school, and do you know if this is commonly done? The main difficulty I have with restricting phone use is that these days it can entirely isolate the kid socially. If the kid had a good number of friends who knew how to interact without in person I'd be a lot more comfortable.


How big is the school, if you don't mind me asking? And was it something pushed by the parents or the school itself? Would you mind sharing the papers/mails regarding justification & such?


How are you measuring O2 levels?

I’ve also been experimenting with a slightly elevated mattress recently, it seems to help quite a lot for my OSA.


I've gotten a full bed foam wedge in the past. I can't find the original one I bought before but I think the below is similar. Its much better than a short wedge pillow if you are a side sleeper. The only problem is initially you will slide down slowly but it gets better over time. I used it for a different reason because I used to get GERD issues in the past and elevation would help a lot.

Do you mean a petrol leaf blower? Because of the motor emissions or the blowing?


It's a fair question, and the answer is "I don't know." Petrol leaf blowers are typically 2-stroke engines which are incredibly polluting (even in an absolute sense compared to a modern 4-stroke engine for a mid-sized saloon). They also kick up a lot of dust. I'm not sure what the balance is. Certainly for e.g. NO2 and hydrocarbons switching to electric will be a huge win, but I'm not sure how much/long the particulates kicked up by blowing contribute.

[edit]

I found a report[1]; on page 22, the median estimated "fugitive dust" emmisions of blowing on a shoulder, or curb is about 480g (1lb) of PM2.5 per hour. It does note that this is a pure calculation and not empirically tested though. The entire range of their calculations put fugitive dust as higher particulate emissions than the exhaust (though the exhaust particulate of a 3hp leaf-blower (i.e. high-powered commercial) is already nearly 2 orders of magnitude higher than a modern light-duty vehicle and a 0.8hp (i.e. typical personal-use leafblower)).

Myst would be a perfect game to play on a long flight. Sorting the right controller setup might be tricky though.



Thank you.


This joke’s also a reference to the fast turnover Australia had around that time of prime ministers, due to them getting replaced by their own party.


Since then, UK has claimed the global lead on this. Sorry Oz.


For anyone using or considering a CPAP device, you should also do some research into mandibular advancement devices (MADs). They’re basically a mouth guard that opens your airway by moving your lower jaw forward.

They are lesser known than CPAPs but are much simpler and way less invasive. They’re often well suited for people who are thinner and/or have milder OSA symptoms.

I couldn’t use a CPAP but using a MAD has helped significantly (although perhaps not completely).


I have severe sleep apnea and made the switch from CPAP to MAD a couple years ago. Expensive but covered. Never looked back. Much simpler on every level, works about the same. My wife confirms I don't have apnea episodes.


When you say "covered" you mean your insurance paid for it? Are you in the USA? I understand it's not covered unless you do a series of sleep studies.


yes, in the USA, yes - covered. and I did have to have a sleep test for the cpap, but not the MAD


I remember my sleep doctor mentioning them as an option, but with a risk of altering the jaw's shape.


It's not really a risk. I use a MAD. In the morning I have a little insert that realigns my overbite and do 5 minutes of muscle exercises. If i don't do that i notice alignment issues when I'm chewing. If i do, it's not an issue at all throughout the day. There are studies that have shown that overbite decreases over time but it's not clear if they do the reset procedure every morning.


It already can be used for development, IDEs such as PyCharm perform quite effective live type checking based on type hints.



Acidic foods and drinks will temporarily soften the enamel in your teeth. Brushing right afterwards can remove the softened enamel.

Brushing right after drinking acidic soft drinks or soda is meant to be much worse for your teeth than not brushing.


I thought one weird trick to having good teeth was outright avoiding sugary drinks (soft drinks) and snacks. I always assumed avoiding causes was more important than remediation (teeth cleaning). Anecdotally, it seems reasonable.

That said, flossing gets rid of obvious stuck gunk, so I do that (with care to avoid damaging gums).


It's not just sugar. Soda water would do it too.

And it's not just carbonated beverages. Tea also is acidic


This is exactly right. If you really want to brush after eating acidic foods, at the very least swish generously with water first. Ideally, use a pre-brushing rinse that restores your mouth's pH balance.


Thanks for this comment. Going to change my eating habits as a result.
