Dasein flees from its existence in anguish.

She had been repeating this sentence in her head since she left that classroom on Thursday at 4 pm. In 24 hours she would experience overwhelming frustration from a broken sink and a pile of dirty dishes, the pain killer she indulged herself with due to the insufferable toothache caused by her unextracted wisdom teeth, and finally a piece of bacon with ants feasting on it, lying on the floor of the French patisserie with beige wooden showcase, generous sunlight, and delicious almond croissants.

If she had glimpsed her existence then it is…


Short answer: Not early enough to make us not panic.

A quantum revolution is in the air, powered by formidable computing power and counterintuitive subatomic properties. While many are looking forward to the quantum magic that can dramatically accelerate computations, we may also be launching ourselves into a future where many of our digital information such as online transaction records, emails, website logins are susceptible to quantum attack.

Cryptologists today are worrying that classical public key encryption system will soon be rendered obsolete by quantum computers. However, this is not because quantum computing is so new and ”disruptive“ that it caught cryptographers off guard. Not at all. On the contrary…


A good mix of philosophy of mathematics, phenomenology, history, historiography, communism. Some novels. Update constantly. Some entries come with sarcastic comments.

  1. Currently reading: In Search of Lost Time, Marcel Proust (reading for a class. Will see if I can actually finish. French literature… oh man)
  2. The Roads to Freedom, Jean-Paul Sartre
  3. Being and Time, Martin Heidegger
  4. Wittgenstein’s Lectures on the Foundations of Mathematics, edited by Cora Diamond (Note: Turing-Wittgenstein debate on mathematical ontology is included in this book. Honestly, what can be more exciting than this? …

Soooo… two of your favorite buzzwords just collide…

IBM Q System One

Talking about noise surrounding quantum computing and blockchain — I have seen my beloved city of Cleveland preparing for its comeback as the leader of blockchain technology (the Blockland, as they call it); the word “quantum” showing up on almost every tech prediction list of 2019; The CSO of China’s insurance giant Pin’An announced that the blockchain technology is now ready for mature business application, and most recently IBM’s shiny sci-fi looking Q System One, reportedly the first quantum computer for commercial use…

I don’t have to say more to convince you…


The sip of coffee that I just took tasted bitter than normal, or, to be more precise, I would not know how normal coffee of this kind tasted like. However, since he told me earlier that he over-brewed the coffee, I was intentionally looking for that hint of bitterness in my mouth, and it was there — what a relief.

He just finished cleaning the bowl that was used to hold the pancake batter. Now the pancakes were forming the expected circular shape in the pan. …


1970 Paris Sartre & de Beauvoir

The pancake was in the oiled pan, or, to be more precise, the pancake batter that he just made with an unmeasured amount of pancake mix, one egg, and some 2% milk, was in the oiled pan. The batter started to form the expected circular shape, lightly browning on the edge — soon the smell of flour and olive oil would fill his small open kitchen.

He just finished cleaning the bowl that was used to hold the batter. …
