Take Two: Eshell

take-two:-eshell

This is a contribution to the Emacs Carnival 2025-06: Take Two collection of posts on Christian Tietze’s blog. My first take with Eshell many years back did not leave a good impression. My early expectations was that it should act like any other shell, only to be unpleasantly surprised by it. It took a long […]

I scanned all of GitHub’s “oops commits” for leaked secrets

i-scanned-all-of-github’s-“oops-commits”-for-leaked-secrets

TL;DR  GitHub Archive logs every public commit, even the ones developers try to delete. Force pushes often cover up mistakes like leaked credentials by rewriting Git history. GitHub keeps these dangling commits, from what we can tell, forever. In the archive, they show up as “zero-commit” PushEvents.  I scanned every force push event since 2020 […]

N-Back – A Minimal, Adaptive Dual N-Back Game for Brain Training

The N-Back test is grounded in decades of cognitive neuroscience research. Key studies include: Jaeggi et al. (2008) published groundbreaking research in PNAS showing that dual N-Back training can improve fluid intelligence. Their study found that participants who trained for 19 days showed significant improvements in intelligence test scores. Owen et al. (2010) conducted a […]

Astronomers discover 3I/ATLAS – Third interstellar object to visit Solar System

For only the third time in history, astronomers have discovered a new interstellar object that originated from outside our Solar System. The object, known as 3I/ATLAS, is likely a comet and is much faster than any other interstellar object found before.  The object appears to be hurtling towards our Sun at about 60 kilometres a […]

Whole-genome ancestry of an Old Kingdom Egyptian

whole-genome-ancestry-of-an-old-kingdom-egyptian

Abstract Ancient Egyptian society flourished for millennia, reaching its peak during the Dynastic Period (approximately 3150–30 bce). However, owing to poor DNA preservation, questions about regional interconnectivity over time have not been addressed because whole-genome sequencing has not yet been possible. Here we sequenced a 2× coverage whole genome from an adult male Egyptian excavated at […]
