You have between 100 and 300L of fresh water in your cumulus and 10L in your toilets. If you have a bath, you can also fill it as soon as alert is raised and have enough water for days. Yes, it’s not the perfectly clean tap water, but it’s emergency situation. And you have an immune system for this.

Unless you go on treck or on country with suspicious water, don’t bother with purifying tablets. You’ll have to throw them away and replace every 2 years. They also give some unpleasant taste to water.

Yeah, they are generally bought by English retired.

neovim, because it’s much nicer and user friendly than vim.

I comment because this is how a social network works, and this is how you keep lemmy alive. My comment has generated a dozen of other comments, so he achieved his goal.

There is not a single question that’s already have been answered on internet, so there no point on asking anything on social plateforms except just for the sake of interacting with other peoples.

Lemmy is not stackoverflow 😉

Don’t know how list are implemented in Python. But in the dumb linked list implementation (like C++ std::list), each element has a “next” member that point the the next element. So, to have list length, you have to do (pseudo code, not actual python code):

len = 0
elt = list.fisrt
while exist(elt):
    elt = elt.next
    len++
return len

Whereas to test if list is empty, you just have to:

return exist(list.first)

Isn’t it because list is linked list, so to get the Len it has to iterate over the whole list whereas to get emptyness it just have to check if there is a 1st element ?

I’ too lazy to read the article BTW.
