  • Looking for ideas: offline entertainment device

  • I don't think jailbreaking will change a lot power consumption. Maybe even the opposite, as you may break service that aims to decrease consumption.

    On my stock android (cross call core X4), in airplane and battery saver mode, it can last for a week. I use it when trekking and just use GPS with osmand from time to time.

    Just be sure to disable all shitty apps (WhatsApp, gmail, etc...)

  • Python Performance: Why 'if not list' is 2x Faster Than Using len()

    Jump

  • 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 😉

  • Python Performance: Why 'if not list' is 2x Faster Than Using len()

    Jump

  • 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)

    Jump

  • 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.

  • spectrum rule

    Jump

  • You're right, I've mixed denombrability of the set and sortability of the measure (don't know if it is the right words in engkish).

    On my side, I'm not sure about dimension or continuity of gayness norm.

    Jump

  • Every non-empty finite subset of N admit a maximal element. As humanity is a finite subset of N, there is someone there which is the gayest of all.

  • Assuming we live in a simulation, at which layer are we ?

    Jump

  • Holy fucking shit ! I just fall into this rabbit hole, I was suppose to mow the lawn and go to the dump this morning, my wife will kill me 😅

  • Assuming we live in a simulation, at which layer are we ?

    Jump

  • Agree, we don't know the rule of layer above ours. It has been demonstrated that Mathematics are the same at any point of our universe, but I'm not aware of anything outside of universe. And I doubt this could be even demonstrable.

    At least, we are sure that, starting from ou layer, there is a finite number of possible layer below.

  • If we do the analogy with CPU, then plank time is CPU clock, and plank length the discretisation of field, a bit like floating point precision. At each clock, causality influence the cell next to her.

    But in this case, why the universe so huge and why speed of light so slow ?

    I mean, speed of light is fucking slow compared to universe, but quite instantaneous at our scale. It seems like the simulation has been designed to work well at our scale. So, are we the subject of the simulation, or an unexpected side effect ?

  • A T-shirt a friend gave me when going back from China. It had a small smell, so I put it in washing machine. It end up completely torn in several part... I didn't,t even had a chance to wear it once 🤣

  • 4 Ways to Live Without a Car

    Jump

  • Yes, we have this, but they don't pick above 1m3. Which is stupid, because for less than 1m3, I put it in my own composter.

  • 4 Ways to Live Without a Car

    Jump

  • I came by bike to work during 10 years, I also have a trailer for my daughter, do regular cyclo-tourism, including crossing Scotland and Iceland with tent and bike.

    Trust me, I know what a bike can do. But when you just discharge 4 tons of concrete from the delivery truck and noticed you missed a few bags of cement, you really are not motivated to drive 15km with cargo bike.

  • Dude, do you have any idea if what 5m3 grass, woods and leaves represent in a 700m2 garden, and the time it would require to compost it naturally ?

    There is an "organic factory" (don't know how to translate it) were people can bring their organic waste close to my home. They have big crusher for wood, and several areas to maturate the compost. You can buy premium organic compost for your garden for like 0.1 euros per kg. You can also come with your trailer and take a few tons if you want.

    It is also used by townhalk to decorate round about, public PARC, etc...

  • Mmm'k, I'll take the bike next time I'll bring 300kg of concrete from the store...

    The problems is not having a car. The problem is taking its car everyday for less than 5km to go to work.

    Yes, you can live without any car if you live in a big city (in 30m2 apartment 😝), eat in restaurant, go to cinema, etc... and love this way of living.

    But if you want a house, with decent garden, close to nature, then it becomes hard to live without car. Not that you must take your car everyday, I have an electric 50cm3 equivalent bike to go to work.But yeah, when I do the garden and have 3/4m3 of organic waste, it's hard to evacuate this by bus...
