  • if you have an oled display, then if a video game is brighter it costs more energy because the LEDs turn on more.

    if have an lcd display, there’s a backlight that always has the same brightness and crystals blocking the light, which makes the image. meaning a brighter scene doesn’t take more power, since the backlight doesn’t use more energy.





  • appliences that connect to your internet are supposed to be secured, but cheap Chinese ones usually arent. this means they can easily get hacked and added to a botnet thats used for DDoS attacks. I once saw a screenshot of someone whose washing machine uploaded ~30GB of data per month.

    the best thing to do against this is to just not connect them to the internet.



  • Unix computers store time in seconds that have passed since january first 1970. one there have been too many seconds since 1970, it starts breaking. ‘signed’ is a way to store negative numbers in binary. the basics of it are: when the leftmost bit is a 1, it’s a negative number (and then you do some other things to the rest of the number so that it acts like a negative number) so when there have been 09999999 seconds since 1970, if there’s one more second it’ll be 10000000, which a computer sees as -9999999.
