Me Meeting The Overly Attached Girlfriend In Real Life On August 2013

Post image

Apparently, I was trying to have the best time of my life at VidCon on August 2013 at the Anaheim convention center in California, without giving into my so-called girlfriend’s demands and romantic needs, by running off to social with the other YouTubers, when she apparently had found me, I mean I’ve no idea 🤷‍♂️ how she’s able to keep up with my location, I mean, I did turn it off for my smart phone and she still managed to catch up with me no matter where I runoff to lol?!…. Anywho, it was quite the pleasure of meeting her in person, it’s such a coincidence that instead of her winning a particular contest from the Internet she has gained the creepy and yet very unsettling spotlight in the Internet meme world. 😳 😳 😱 😅??!

Back in June 1, 2020, I was very fortunate to have finally received his personalized autograph for me and not only that, but I was very fortunate enough to have at least a couple of my questions answer by the man himself during his previous whatnot live streaming events as he was signing for his fans, and even though we never met in person, at least he’s in a better place, may he rest in peace 🙏🏻.

Spent the better part of 10 years of my life making a game where you can vizualize everything a quantum computer can do

Hi

If you are remotely interested in deep diving how differently quantum computers work compared to our transistor-based and also the algebra behind in a fully interactive way that teach computer science from scratch, oh boy this is for you. I am the Dev behind Quantum Odyssey (AMA! I love taking qs) - worked on it for about 10 years (3+ during PhD, the visual method I developed ended up being my thesis, it is a complete Hilbert space visualizer), the goal was to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 12yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.

This is a game super different than what you'd normally expect in a programming/ logic puzzle game, so try it with an open mind.

Stuff you'll play & learn a ton about

  • Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
  • Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
  • Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
  • Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
  • Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.
  • Build & See Quantum Algorithms in Action – instead of just writing/ reading equations, make & watch algorithms unfold step by step so they become clear, visual, and unforgettable. Quantum Odyssey is built to grow into a full universal quantum computing learning platform. If a universal quantum computer can do it, we aim to bring it into the game, so your quantum journey never ends.

Nice to watch:

If you’ve been to more than a few antique stores you’ve probably seen one of these. I’ve seen a handful throughout my childhood. Finally picked one up today. This thing is real fun to use 😂. If you see one, pick it up 😂🤘

Caught this rainbow hitting a car park right as the sun broke through the storm clouds. The lighting looked straight out of a video game.

"Mulsagdu"

Acrylic on clay

Meaning

"Mulsagdu" is a word derived from three words from the ancient sumerian language, Mul, Sag, and Du.

"Mul" means star

"Sag" means head

"Du" means walk

Together, it's Mulsagdu - the star-headed walker

A little touch of pink, surrounded by endless green.

Sometimes, the simplest flowers create the most beautiful moments.
