- Comment on Python Performance: Why 'if not list' is 2x Faster Than Using len() 1 week ago:
If the point of Lemmy is just to generate as many comments as possible with everyone just assuming whatever they want about linked articles without reading them I’ll quickly leave again. I’m here for informed discussion, not for a competition in generating engagement
- Comment on Python Performance: Why 'if not list' is 2x Faster Than Using len() 2 weeks ago:
except for c++ it was just to avoid a single function call, not extra indirection. also on modern compilers size() will get inlined and ultimate instructions generated by the compiler will likely be the same
- Comment on Python Performance: Why 'if not list' is 2x Faster Than Using len() 2 weeks ago:
why comment if you don’t even want to read the article? python lists are not linked lists, they’re contiguous with a smart growth strategy.

wait, so compagnies selling heat pumps will be able to say they sell propane and propane accesories?
- Comment on 6* months away now. If you're on 10, do you plan to upgrade? Make the jump to Linux? 3 weeks ago:
good thing about the terminal is it scares most general users so much that they won’t touch it even with instructions. There will be many issues, but I don’t think people running random commands in the terminal will be one
- Comment on Owing your home today is nearly impossible, but even if you did the ever increasing property taxes will bury you 1 month ago:
you could have progressive taxes on wealth as well. there’s a difference between having one house worth 500k and having 500 million in shares
- Comment on Why can't we go back to small phones? 1 month ago:
this right here is the issue, people don’t even remember the size smartphone used to be. I’ve got a phone that’s one of the smallest available that still have decent hardware. the screen is still 6.1 inch. your example of a reasonable size is 6.3 inches.
what op and I are actually looking for is something around 5 - 5.3 inches instead, like smartphone used to be. For that size, all that is available today is no-name chinese phones with shit hardware and no support. the big brands are busy selling 6.2 inches as “compact” where it used to be considered phablet size
- Comment on ‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off 2 months ago:
To be a positive impact, they just need to be less carbon intensive thans the energy they displace. According to the first results on google, (presumably utility-scale) solar is about 12 times less carbon intensive than natural gas and 20 times compared to coal. So as long as you’re replacing base load and not utility solar, balcony solar could be as much as 10 times less efficient and still come out a net positive.
Keep in mind also that these numbers keep improving as solar panel manufacturing becomes more efficient and starts using more green energy itself over the coming decades
