As a good example of how I’m doing: I managed to go to the swimming pool today without a towel.
I did check in the elevator down whether I had brought my swimming trunks.

Haben irgendwelche Grüne sich zu Zoran geäußert?
Ich habe bisher noch nichts gesehen und sehe eigentlich inhaltlich kaum Überschneidung die es rechtfertigen würde.

Fixing a mistake I made a long time ago is a good opportunity to review all my logins, mark which ones need phone 2FA and also close a lot of accounts.
Good riddance Xing! It was never good.

A day of parent teacher conferences and every time we do this little dance, it becomes more and more clear that the most important thing my kids learn in school is that effort is not rewarded.
That I don't have that much issue with because it is true, but they (and we) also don't get any agency.

Back to City Mapper we go.
(Telling that the enormous fees Google charges on this product aren't enough for it to be maintained.)

During trick-or-treating yesterday I was super tired and didn’t parse what happened.
Turns out I was offered baked goods by our evil vice mayor which I refused. My political instincts remain on point.

Every time I want to do something with parental controls in any app (Spotify, Netflix, iOS), it’s either impossible to do or impossible to figure out.
It’s not like we can meaningfully do anything about it or switch to a different provider where things are better. I guess we’ll exit at some point.

Alternative licenses like the Forklift Certified License are a good and necessary counter-reaction to open source becoming a corporate hollowed out shambles.
Any time somebody mentions a big project that's open source, my first question is: “How fake open source is it?”

This is what people mean when they accurately say that Silicon Valley CEOs are "bitch coded".
Nick Clegg really nails the most disappointing and pathetic aspect of Silicon Valley. It’s an industry full of the richest and most powerful people in history, who believe they’re victims because their power is not absolute.
It hurts to be so rich yet not be treated like kings by us “peasants.”
