From Ada to XL in 25+ years…

At the Paris Open Source Summit, I had a long discussion with engineers from AdaCore, that reminded me of the early roots of XL in Ada. I have never really retraced the steps along the way, and this was an interesting walk for me. I thought I'd share… My interest in programming languages is quite old. … Continue reading From Ada to XL in 25+ years…

The bogus “interpretations” of quantum mechanics

I've not written on this blog for a long time. A talk in Mouans-Sartoux yesterday prompted me to write this rant about what I will (demonstrably) call bogus interpretations of quantum mechanics. Specifically the "dead and alive cat" myth. Schrödinger's cat One of the most iconic thought experiments used to explain quantum mechanics is called Schrödinger's … Continue reading The bogus “interpretations” of quantum mechanics

Going to deep space, now theoretically possible?

I have already discussed earlier why we need to go into deep space if we want to have a future as a specie. But the problem is how to do it? Until now, this was considered impossible. A first theoretical step had been made, with the Alcubierre drive, an interesting solution to the equations of general … Continue reading Going to deep space, now theoretically possible?

How to unify general relativity and quantum mechanics

Unifying quantum mechanics and general relativity has been a problem for decades. I believe that I have cracked that nut. Special relativity: Philosophical principle: Laws of physics should not depend on observer's speed. Math: Lorentz transform, new way to "add" speeds. Issues it solved: Maxwell's equations predict a value for the speed of light that … Continue reading How to unify general relativity and quantum mechanics

La SNCF en flagrant délit d’IP-tracking

La SNCF affirme ne pas pratiquer l'IP tracking, J'ai du mal à y croire. Il y a quelques minutes, ma femme va sur le site Voyages SNCF, et demande un billet Paris-Antibes. Prix du billet: 80€. "Attention, dernières places à ce prix", bien sûr. Mais à un moment, elle fait une erreur, et décide de … Continue reading La SNCF en flagrant délit d’IP-tracking

Paul Graham recommends doing things that don’t scale

As usual, Paul Graham writes an interesting piece about startups. He recommends doing things that don't scale. Thinking like a big company is a sure way to fail. It's a reassuring piece for the startup creator that I am, because at Taodyne, we are indeed in this phase where you do everything yourself and you'd … Continue reading Paul Graham recommends doing things that don’t scale
