  • A class of 200 students performing much worse than the last class is very unlikely. 200 Students is enough to make even small differences statistically significant.

    A single test being much harder than the last test is much more likely, since it isn’t an averahe of 200, it’s a single datapoint.

    That’s why if this semester’s class performed much worse than last semester’s, you can assume it’s because of the test, not the students.








  • Windows 11 doesn’t even support first gen Ryzen CPUs. The amount of hardware that runs Windows 11 without tinkering is a tiny fraction of the hardware that runs Fedora Workstation without tinkering.

    Linux is much better with drivers and hardware support than Windows. Windows only works well if you use the very small subset of hardware it supports.


  • My cat likes to jump on my shoulders. When I wear clothes, she uses her claws to keep her balance. But when I’m topless, she doesn’t use her claws (and instead awkwardly tries to get down). It seems like she knows that clothes mean I’m protected and that she can use her claws without hurting me.





  • Providing expiration notifications costs Let’s Encrypt tens of thousands of dollars per year

    Not doubting them, but I don’t understand how that’s possible.

    Storing the email addresses and expiration dates takes an irrelevant amount of storage space, even if they had billions of cutomers.

    Sending the emails should also not cost thousands, even if a significant amount of customers regularly let their certificates expire (which hopefull isn’t the case).

    So where are the tens of thousands of yearly costs coming from?
