Anon takes an exam

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.

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.

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.

someone teach them LaTeX

When I went to college the dot was used for the dot product (scalar product) of two vectors while the cross was used for the cross product (vector product) of two vectors.

Since in this case numbers (read: one-dimensional vectors) are multiplied, the dot product is used, which should be denoted by a dot.

(But really, if I were to write a formula in Latex I would just use the * symbol, too.)

Can I ignore flatpak indefinitely?

Another upside is the easy permission management.

You can revoke network access from your password manager to reduce attack surface; you can revoke camera access from your chat app to prevent accidentaly enabling it; You can restrict an app's file system access to prevent unwanted changes; etc.

It's not yet fit to protect from malicious apps, but it still finds some use.

PSA: LetsEncrypt ending expiration notification emails

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?
