Despite my poor AI prompting skills, this image looks quite as evil as the Shai-hulud npm attack, right?

I'm my own worst critic. It's tiring. Very tiring...

No matter how much I try to convince myself that "good enough" is okay, I still don't act like it most of times.

I guess it's a long-time learning process.

Recognizable?

Chatgpt seems very much down at the moment. Does that mean that I need to be creative myself?

Provider internet modem replaced by a new one. Let's hope my dodgy internet is finally fixed now. Non or poorly working internet is so frustrating.

If you'd bought crowdstrike stock shortly after the incident of last year, you'd (almost) doubled your money.

How to stop Meta from using your data to train its AI At the end of May, Meta will start using Europeans’ data to train its AI. Here is how you can exercise your rights and prevent it.

If you're in Europe and you haven't objected to meta using your data for AI training purposes it's about time. You still have a little bit of time to do so before they start with it.

Yep, it's proven over and over again that it's better not to rely on the employees but make sure you build in a check against previously breached ones when users create a new password.
