All right, I have muted all fucking words related to politics in my settings, my feed is full of fucking politics. Just untagged images circumventing the blocks. Going on a blocking spree now, regardless of whether I agree with the politics or not. Fuck you for disrespecting my choices.

I've recently gotten into sharpening kitchen knives. Everyone has their favorite sharpness test, but for me, one stands above all: can the knife easily chop fresh basil without *any* bleeding?

It is not easy, but for someone using fresh basil constantly, the sharpness is crucial.

The instant I clicked on "Submit", not a second later, I got downvoted. What is going on?

Once upon a time, almost the entire extended ASCII code set was printable in Codepage 437. I grew up with that character set and learned to read binary files quite well in it. In an effort to relive those days, I made a little program that prints binary files in the CP437 charset.

My lovely Emerald of Chivor; by far the most impressive (if not very practical) ink I have. The bottle certainly does justice to its contents!

One of the best photos I've taken, a gorgeous mushroom in Uppsala's Stadsskogen.
