Filesystems: More Perilous Than You Think

2025-01-23

A Deconstruct 2019 talk revealed shocking truths about filesystems: from the inconsistencies and difficulty of correctly using the file API, to serious bugs within filesystems themselves and the high error rates of disks, data corruption is rampant. The speaker delved into the atomicity issues of file writes and the challenges posed by different filesystem modes (e.g., ext3/ext4's data=journal, ordered, writeback). Even experienced programmers struggle to avoid mistakes leading to data loss or corruption. The talk also analyzed errors in popular databases and version control systems and suggested using databases instead of files to improve data reliability.

Gene-Edited Pigs: A Biotech Breakthrough or Ethical Grey Area?

Genus has created pigs genetically resistant to the devastating PRRS virus by removing the virus's cellular receptor. While similar to the controversial CRISPR babies experiment, the pig project faces fewer ethical concerns due to its economic benefits—PRRS costs the US over $300 million annually. The article contrasts this achievement with other, less serious gene-editing projects, such as attempts to resurrect extinct animals and create fantastical creatures, highlighting the potential and ethical dilemmas of genetic engineering in agriculture and beyond.

The Mystery of the 8x19 Font in Intel BIOS

2025-08-18

This article details the author's journey to uncover the origins of a non-standard 8x19 font found in Intel motherboards' BIOS. Starting with a BIOS POST screenshot from an Intel AN430TX board, the author discovers early Intel boards (like the AN430TX and AL440LX) used a custom 8x19 font, unlike the standard 8x16. To solve the mystery, the author attempts to decode BIOS images, ultimately succeeding with a clever method. This reveals the font's presence in early BIOS versions, cleverly integrated with the string module to save space. Further investigation shows the font's use across different eras, BIOS manufacturers (AMI and Phoenix), and even into later EFI shells. The author speculates Intel, not the BIOS manufacturers, is the font's source, analyzing its role in display technology's evolution.

WWII: German Ace Escorts Damaged US Bomber

On December 20, 1943, during WWII, a severely damaged US B-17 bomber, the "Ye Olde Pub," was unexpectedly escorted to safety by a German Luftwaffe ace, Franz Stigler, after a bombing run over Bremen. Stigler, despite having the opportunity to shoot down the crippled aircraft, chose not to, instead guiding it through enemy territory. This incredible act of chivalry, kept secret for decades, was only revealed years later when the two pilots reunited, forming a lasting friendship until their deaths in 2008. The story highlights an extraordinary moment of humanity amidst the brutality of war.

Windows 11's Blue Screen of Death Gets a Makeover

Microsoft is revamping the Blue Screen of Death (BSOD) in Windows 11. The new design ditches the classic blue screen, sad face, and QR code for a simpler, black screen reminiscent of Windows update screens. Currently appearing as green in test builds, the final color remains unclear. Microsoft aims for faster user recovery while retaining technical details. This is the first major redesign since the sad face addition in Windows 8. The new BSOD simply states, "Your device ran into a problem and needs to restart."

Beijing Apartment Explosion Highlights Unproven Cancer Treatment

A Beijing man, Liu, was making a highly concentrated chlorine dioxide solution in his apartment for cancer treatment. An explosion occurred during an experiment, injuring him and endangering his 3-year-old daughter. Liu claims to have treated over 20 patients, but his evidence consists only of unpeer-reviewed preprints and screenshots of WhatsApp chats, lacking scientific rigor. A patient who underwent the treatment described severe side effects, including excruciating pain. Oncologists strongly question the treatment's validity and emphasize that such an unproven method should not be used outside of clinical trials.

Nirvana's Nevermind: The Unexpected Success of an Album Built on Major Chords

2025-05-04

In 1991, Nirvana's *Nevermind* unexpectedly became a critical and commercial sensation. Its raw guitars and unapologetic sound captivated listeners. Over 30 years later, a re-examination reveals a key ingredient: the almost exclusive use of major chords, eschewing minor chords and complex chord progressions (7th, 2nd, 4th, 6th, 9th, dim, aug). This created a unique harmonic language, bold and innovative for its time. Interestingly, Kurt Cobain seemingly worked intuitively, unaware of any musical rules he was following. This demonstrates the power of raw emotion and instinct transcending technical proficiency.

Intuitive Queuing Theory: A Dice-Rolling Simulation

2025-04-10

This article uses a dice-rolling simulation to provide an intuitive understanding of key queuing theory concepts. The author simulates an M/D/1 queueing model, where arrivals follow a Poisson distribution and service time is deterministic. By varying the service rate, the simulation demonstrates how queue length changes under different utilization factors. Results show that as utilization approaches 100%, average queue length increases significantly, even tending towards infinity. The simulation aligns well with theoretical results, and explores the reasons behind queue length fluctuations.

Metaphorical Brain Talk in Psychiatry: A Historical and Contemporary Perspective

2025-09-07

This essay examines the persistent use of "metaphorical brain talk" in psychiatry, where mental illnesses are explained using simplistic notions of brain structure or dysfunction. From early 20th-century critiques by influential figures like Adolf Meyer and Karl Jaspers, to more contemporary examples involving researchers like Paul Meehl and Nancy Andreasen, the essay traces the enduring presence of this metaphorical language. Despite advances in neuroscience, phrases like "synaptic slippage" and "broken brain" remain commonplace. The author uses the monoamine neurotransmitter hypothesis as a case study, highlighting its limitations in explaining disorders like schizophrenia, mania, and depression. A real-world anecdote illustrates the impact of such metaphorical explanations on patients and the public. The essay concludes by noting that the pursuit of external funding and pharmaceutical advertising have exacerbated the prevalence of this phenomenon.

Mice Exhibit Paramedic-Like Behavior: Neural Mechanisms Unveiled

Mice Exhibit Paramedic-Like Behavior: Neural Mechanisms Unveiled

UCLA researchers have discovered that mice display prosocial behavior towards unresponsive conspecifics, characterized by intense head-directed grooming. This behavior is driven by an amygdala-regulated response. Experiments showed mice differentiating between sedated and stressed peers, grooming the head of sedated mice and the body of stressed ones. Neural recordings and optogenetic manipulation pinpointed the medial amygdala (MeA) as crucial; silencing MeA GABAergic neurons suppressed head grooming while activation enhanced it. This research illuminates the neural basis of prosocial behavior in mice, offering insights into broader animal social behaviors. This falls under the Tech category.

The Design System Dilemma for Rails Apps in 2025

2025-04-10

Choosing a well-made design system for your application should be a simple task in 2025, yet for Rails apps, it's not. The author, building Business Class, faced this dilemma. Initial attempts with Bulma and Tailwind proved unsatisfactory. The article explores several options: shadcn/ui (requiring Rails integration), daisyUI (lightweight but lacks JavaScript), Flowbite (officially supports Rails, but not fully open-source), Preline (feature-rich, freemium), and RubyUI (built for Ruby, but uses Phlex and requires leaving ERB). Ultimately, the author concludes that continuing with a Tailwind-based approach, either leveraging a pre-built UI library or building a custom theme, is the best path forward.
