lsds: A One-Stop Shop for Linux Block Device Settings

2025-05-09

Managing disks and I/O on Linux often involves running multiple commands like lsblk, lsscsi, and nvme list, then manually correlating their output. To streamline this, a Python program called `lsds` was created. It directly reads information from the `/sys/class/blocks/...` directories, consolidating key disk details into a single, easy-to-read output. This includes device name, size, type, scheduler, rotational flag, model, queue depth, number of requests, and write cache settings. `lsds` is highly customizable, allowing users to specify which columns to display and providing a verbose mode for tracing information sources. This tool significantly simplifies the complexity of managing Linux disks.

Reading Passport NFC Chip Data with Python

The author attempts to read the NFC chip data from their cancelled passport using the Python library pypassport. Due to the passport being cancelled, a portion of the MRZ (Machine Readable Zone) is missing. The author reconstructs the MRZ from other information on the passport and successfully reads the passport information, including biometric data. The article details the composition of the MRZ, checksum calculation methods, and the reading process, and discusses the possibility and practical value of brute-forcing the MRZ. Ultimately, the author demonstrates that while theoretically possible, brute-forcing is very difficult in practice, and reading the information directly from the passport is much more convenient and efficient.

Inflammation and Aging: Not a Universal Truth

Inflammation and Aging: Not a Universal Truth

A new study from Columbia University challenges the long-held belief that inflammation is a universal hallmark of aging. Researchers compared industrialized populations (Italy and Singapore) with non-industrialized Indigenous groups (Tsimane of Bolivia and Orang Asli of Malaysia). They found that while 'inflammaging' (chronic, low-grade inflammation associated with aging) was prevalent in industrialized societies and linked to chronic diseases, it wasn't consistently observed in the Indigenous groups. In these populations, inflammation was more strongly correlated with infection rates than age. This suggests that inflammaging may be a byproduct of industrialized lifestyles rather than an inherent part of the aging process, opening up new avenues for intervention and highlighting the importance of considering context-specific factors in aging research.

Impossible Task: Dissecting a Square into an Odd Number of Equal-Area Triangles

2025-04-19

This article explores a deceptively simple geometric problem: can a square be dissected into any number of triangles with equal area? The answer, surprisingly, is complex. In 1970, Paul Monsky proved that it's impossible to dissect a square into an odd number of equal-area triangles. The proof cleverly combines Sperner's Lemma and 2-adic valuations. By ingeniously coloring the vertices of the triangles and analyzing the number of factors of 2 in the triangle's area using 2-adic valuation, a contradiction is reached, proving the proposition.
