A review and introspect on the second 100 articles written on Bytepawn.
Marton Trencseni - Fri 27 September 2024 • Tagged with openai, chatgpt, sam, altman
A few days ago OpenAI CEO Sam Altman published an article titled The Intelligence Age. I used OpenAI's new o1-mini
model to critique Sam Altman's writing of its own future.
Marton Trencseni - Sun 22 September 2024 • Tagged with people, management
I detail my structured approach to managing one-on-one meetings within a 40-person data team, emphasizing people management principles like radical transparency, tailored meeting cadences, and strategies to navigate common managerial challenges to foster a supportive and productive work environment.

The article explains the Bell inequality using Monte Carlo simulations in Python, and shows how non-local action-at-a-distance can be used to break it with entangled qubits.
Marton Trencseni - Sun 18 August 2024 • Tagged with physics, quantum, mechanics, qubit, entanglement, epr, bell
This blog post explores foundational quantum mechanics concepts such as superposition, entanglement, and the challenges posed by locality and determinism, while highlighting the historical efforts of Einstein and Bohm to reconcile these phenomena with hidden variable theories.

In February 2016, I made a life-changing decision to leave Hungary and seek opportunities abroad, starting in London and later moving to Dubai. This essay explores the multitude of reasons behind my choice and why I have no immediate plans to return to Hungary.
Marton Trencseni - Thu 01 August 2024 • Tagged with polya, problem, solving
I discuss Polya's How to Solve it approach to mathematical problem solving and the 2010 paper Teaching general problem-solving skills is not a substitute for teaching math.
Marton Trencseni - Mon 01 July 2024 • Tagged with cv, screen, hiring
Screening CVs is a critical step in the hiring process, used to determine which candidates progress further in the hiring funnel. While the approach to CV screening can vary by company and industry, the primary goal remains the same: to identify candidates with the potential to succeed in subsequent interview stages.
Marton Trencseni - Mon 17 June 2024 • Tagged with javascript, async, message, queue
In this final post on the toy Javascript async message queue server implementation, I make it compatible with the Python version. I use the library of unit tests developed previously to ensure identical behaviour between the two codebases.
Marton Trencseni - Sat 15 June 2024 • Tagged with python, async, message, queue, unit, test
I write a small library of unit tests for the message queue servers.
Marton Trencseni - Sun 02 June 2024 • Tagged with randomness, extractors, biased, coin, fair
I apply NIST's suite of statistical tests to my randomness extractor implementations from the previous posts.
Marton Trencseni - Sun 26 May 2024 • Tagged with randomness, extractors, biased, coin, fair
I discuss various models of biased bit sequences, and how to extract uniform random (or close to it) output bit sequences from them, illustrated with Python code.
Marton Trencseni - Wed 22 May 2024 • Tagged with python, async, message, queue
In this final post on the toy Python async message queue server implementation, I make further feature and code improvements.
Marton Trencseni - Sat 11 May 2024 • Tagged with javascript, async, message, queue
I write a somewhat more complicated, but still relatively simple async message queue server in Javascript.
Marton Trencseni - Sun 05 May 2024 • Tagged with javascript, async, message, queue
I write a simple, bi-directional async message queue server in Javascript.

Why are Randomized Controlled Trials (RCTs, known as A/B testing in much of the industry) testing is widely regarded as the golden standard of causal inference? What else can a Data Scientist do if A/B testing is not possible, and why are those alternatives inferior to A/B testing?
This papers shows, using 15 experiments (for ads on Facebook) where a RCT was conducted, that common observational methods (run on the Facebook data, by ignoring the control group) severely mis-estimate the true treatment life (as measured by the RCT), often by a factor of 3x or more. This is true, even though Facebook has (i) very large sample sizes, and, (ii) very high quality data (per-user feature vector) about its users which are used in the observational methods. This should be a major red flag for Data Scientists working on common marketing measurements (such as marketing campaigns) using observational methods.

Last year, in 2023, Dennis Austin, one of the original developers of Powerpoint passed away. The news made it to the front page on Hacker News, and prompted a lively discussion of the merits of Powerpoint itself. I posted a top-level comment, which itself sparked a lively thread of responses. In this post I will expand and extend my points about Powerpoint in a business settings, after pointing to hard-learned lessons from Edward Tufte and Jeff Bezos.

Based on the book Compact Stars by N. K. Glendenning a general relativistic treatment of pressure and energy in compact stars is given, followed by simple models of neutron and quark stars. Hypothetical strange quark matter and strange stars are introduced highlighting the importance of sub-millisecond pulsar detections. (Note: this is a student paper I wrote sometime in 2008-2010.)
Marton Trencseni - Tue 09 April 2024 • Tagged with ab-testing
I run Monte Carlo simulations of content production over random Watts-Strogatz graphs to show various effects relevant to modeling and understanding Randomized Controlled Trials on social networks: the network effect, spillover effect, experiment dampening effect, intrinsic dampening effect, clustering effect, degree distribution effect and the experiment size effect. I will also define some simple metrics to measure their strength. When running experiments these potentially unexpected effects must be understood and controlled for in some manner, such as modeling the underlying graph structure to establish a baseline.

Even since I've had a 386 in my room as a teenager, I've taken computers apart and modified and upgraded them. When getting a new workstation computer, I have never bought a pre-assembled one (like a Dell or HP), I always buy the components and build it myself. I've been doing this for 30+ years, so I'm used to it, it's part of my lifecycle. I built my current workstation in 2022, but due to reasons I describe in this post, I've been making a fair amount of modifications to it ever since. Finally, now in 2024 April, I feel that the system has come together and is perfect — I don't want to or plan to make any more changes to it.
