You can ' t be sure about that until he takes the test ! <| sep |> Todesfuge Paul CelanDaddy Sylvia PlathEating Fried Chicken Linh DinhAnatomy Marc Escalona GabaHow I Get My Ideas Dean YoungJealousy MeiMei Berssenbrugge <| sep |> Thanks . This did help with the spinner , but still didn ' t help the flash of white when opening new tabs . Changing browser . display . backgroundcolor helps remedy this , but the browser has to be restarted for it to take effect . I guess the only thing left is figuring out how to to it in Stylish . <| sep |> It ' s not really true . Especially in case of space systems . Every mechanical change follows a lot of additional constraint violations for the spacecraft total mass , mass distribution , center of mass , vibration ranges , gload ranges , mass changes automatically have impact on how thrusters , gyrosreaction wheels work on the spacecraft , this might also have impact on power requirements size of solar arrays , which again modify the total mass and mass distribution . Fixing all those constraints is difficult and is done with so called Concurrent Design . On the other hand changes in software , especially bug fixes so no expected changes in nominal bahaviour have almost zero impact on any other system . There might be some impact on onboard data handling if the fixed version needs more CPU power , but it ' s not very common .
