There are many professional examples outside of teaching (construction, lab based science, field work, engineering, healthcare, retail) where a calculator, not necessary a programmable one, is useful because the environment restricts the use of computers due to safety, security or practicalities.
We have a specific area for
drawing so the ‘mess’ is confined to a small area. Our daughter is happy to likes to give the drawings away and isn’t overly attached to them after they’ve been displayed for a short while - I don’t personally see this as mess as I am also quite proud of her pictures. If I judge magnetic tiles by the same measure I should also include the storage space taken up by a large plastic box of magnetic tiles, the resistance to tidy away their tile creations and the frustration when younger siblings get involved!
After my daughter turned 4, the ‘toy’ with the most play time and lowest clean up time was a good pad of blank paper and colouring pencils. The bonus is that it takes up little room and is therefore highly portable. Furthermore, if you forget it, you can replace it easily and cheaply!
In the UK we have the 111 NHS non-emergency telephone service - they don’t give medical
advice but triage you based on your symptoms. Either a doctor will call you back, they will tell you to go the non-urgent care centre or A&E (ER) immediately.
Two things, no oil as others have suggested but also frying eggs does not require a very high temperature, around 150 Celsius and your eggs don’t look particularly browned (which is how I prefer them too) so you aren’t exercising the Maillard reaction, which generates the PM2.5. Try again with browning a fatty cut of beef or pork steak in oil which require higher temperatures where lots of browning is occurring and you are also closer to the smoke point of the oil.
Is this the same with EV though? The power of the installed engine is more nuanced, for example the full power is limited by software already to prevent wheel spin and improve range. Also, in the UK EVs are listed as a 0cc engine on the vehicle ownership records so effectively have no engine.
I wouldn’t buy Tesla again but I’ve never experienced software issues in mine. Although some of the menus could be re-arranged for clarity, it’s otherwise clear and responsive. The app is great and the third party apps are even better. I’ve not heard positive things from VW or MG owners in terms of software either. Is there any good alternative to Tesla in this domain?
There was one running in Frome, UK but unfortunately these community things are hard to keep going and it has now closed. The issues are cost of storage space, insurance, staffing etc.
Same for me, I had to press the options button on iOS when uploading and set the format to ‘most compatible’. It now works but the aspect ratio of the image is squashed.
My thoughts are that even after 80% usage the battery still has a second life for use in home power storage. Even after that most of the battery parts can be recycled. I think that battery trade-in schemes will start to become affordable once these reuse and recycling routes are scaled up.
These would be great in the UK where we have smaller gardens and poor access. Typically access to rear gardens in semi-detached housing stock is down a narrow path between then houses. For terraced houses I’ve seen someone drive a mini-digger through the house to access the garden.
In the UK first inspection is at 3 years and then every year after that. I wonder if the UK data looks any different due to the more onerous inspection schedule.
Cool project and I’d really like to try something similar with a 4G/5G connection so it doesn’t rely on site WiFi.
I don’t think your cost comparison is fair between the rpi and hosting. I host my website on a £1/mo shared vps and for my energy costs that equivalent to running a low power server at home, ignoring all the other benefits of it being off-site.
High energy gammas have a relatively low cross section, most are going to pass right through the chip. If you add a too little shielding, or don’t layer shielding appropriately you are going to stop more gammas but produce lower energy x-rays from the shielding, which have a higher cross section, potentially increasing your chip dose.
