I really enjoy the sense of power I get from telling companies to fuck off into oblivion when they show/send me simping "are you sure you want to cancel your subscription?" messages. Yes, I have never been more sure of anything in my life. Thank you for letting me self actualize.

As an official #eink stan, there’s a strong urge to buy an E-ink monitor and develop a #hyprland theme that works well for grey scale displays. I’ve been on a real “reducing distractions” kick lately. I’ve been sick all week and decided to leave my Apple Watch off, and feel so much better.

Nix represents a different way of building reproducible software, but Nix has its own challenges, and in many ways Docker already won. So what hope is there for something like Nix in the long run? Come find out tomorrow at the @flox.dev virtual event.

I consider myself a pretty normal engineer. A benefit of making systems that allow normal engineers to succeed is that they are generally kinder towards and more supportive of our neurodivergent colleagues (like myself). #adhd #autism #audhd refactoring.fm/p/in-praise-...

Boston Dynamics Dog Unstoppable At Puppy Bowl
GLENS FALLS, NY—Breaking its own record after scoring a touchdown to rack up its 600th point within the first quarter, the Boston Dynamics dog appeared unstoppable at the Puppy Bowl, sources confirmed Sunday. “It looks like Nacho is headed into the end zone, and—oh no, another brutal tackle from Spot, the robotic dog!” said game commentator Steve Levy, who clutched his head and winced as the gadget began emitting a high-pitched noise that caused the few still-standing puppies to crumple unconscious to the ground. “Oof, that’s gotta hurt! This is one dog that sure likes to play rough. It’ll be interesting to see what he does with the arm he’s protracting. Good God, Spot, no. That’s the referee! Run, everybody. Run for your lives!” At press time, the robotic dog was reportedly showboating with a victory dance on a pile of its opponents’ corpses.

One of the most fun things you can do when you’re into #whiskey, #wine, #coffee etc is taste things blind. Without someone to pour for me I’ve made a bunch of blind samples and a few spreadsheets so that I can blind taste a bunch of stuff on my own.
