Porsche proudly advertises "Over 70% of all Porsche vehicles ever built are still on the road today". Is this a testament of the quality and longevity of Porsche cars, or simply a result of the brand switching from niche sportscar manufacturing to mass production around the year 1999?

Recently I was considering whether to introduce some CS style algorithmic interview questions into our Data Science hiring loop, since having an understanding of algorithms and data structures can be useful for Data Scientists. Not having done this soft of interview for a few years I picked up my copy of Daily Coding Problem and starting solving a few problems to refresh my feeling for what it feels like as a candidate, and whether it would give us any useful signals.

Five delightfully cynical half-truths about organizations: the Peter principle, the Dilbert principle, the Gervais principle, Negative selection and the Dunning-Kruger effect.

I summarize the 5 previous posts on probabilistic spin glasses.

I present a simple Monte Carlo solution which finds a 25-letter-unique Worlde wordlist in about 10 minutes.

I use Monte Carlo simulations to explore the dynamic behaviour of probabilistic spin glasses, specifically how saturation scales with $p$ and $N$. 
Marton Trencseni - Fri 31 December 2021 • Tagged with entropy, physics, spin, glass
This is a continuation of the previous articles on probabilistic spin glasses. I run simulations to understand the scaling behaviour for large spin glasses.

This is a continuation of the previous article on probabilistic spin glasses, with improvements to the simulation code and improved entropy computation. 
Marton Trencseni - Sat 11 December 2021 • Tagged with entropy, physics, spin, glass
I run Monte Carlo simulations on probabilistic spin glasses, a simple mathematical model of magnetized matter with short range interactions. I use entropy to characterize the model's order-disorder transition.
