I thought the reason the packs are sealed is to stop amateurs from swapping in cells of differing voltages, which short each other out and cause sparking/fire hazards. There's a reason li-ion battery charging is current-limited, they have no internal resistance.

bittumenEntity · a year ago

As I understand it, it's somewhat the opposite for internal resistance. You need to have current limiting in place because the internal resistance of the cell is turning that current into heat, and heat is the enemy of batteries.

(Probably there's also a complicated chemical reason for current limiting that I don't fully grasp)

Wouldn't len(str(num)) be adequate here? This is a quite literal translation of what the code should be doing: measuring the length of the text representation of a number. The mathematical approach seems a little convoluted, although it serves the purpose of teaching a lesson.

At the bottom of the article they mention that this was discouraged because they hadn't covered strings in the course yet

Not to mention that snow isn't very common in Australia.

Well, at least it does happen. More than I can say for a patriotic 4th of July

Nice list, the but point 2 is a bit ironic, Australians don't celebrate 4th of July at all

Have you considered moving to the other address? /s

Git GUIs are a crutch, perhaps that's what your pupil needs right now, but not forever.

Windows novices may not realise that git can be a local program contained in a folder, so making a repo to test how a verb works costs you nothing.

What does this mean? What sort of "assets?" Why doesn't the site give you a preview of what you'll see when you sign up?

bittumenEntity · 2 years ago

Yeah this really doesn't give anything more than the headline.

Check out Helinox https://helinox.eu/. We have a couple that we take to the parks with us in London and they're great.

bittumenEntity · 2 years ago

In my poorer student days, I actually used one of these (stye) as my primary writing chair in my home. If it's the right size for your shoulders and arms, it works quite well

The fact that in the opening hook the author mistook the state of South Australia for a province just me doubt even more how close to reality this is.
