A new Debian package helper: debputy
The author introduces a new helper tool for producing Debian packages called debputy. This tool takes a different approach to packaging by using a single high-level manifest instead of the traditional debian/install and debian/rules files. Debputy can perform various installation tasks and supports the default flow of 48 debhelper tools. However, there are some features that debputy does not support at the moment, such as debhelper sequence add-ons and packager-provided maintscript files. The author also highlights the rapid feedback feature of debputy, which allows for clean re-runs without affecting the final output. The article concludes with a mention of the author's reluctance to manually maintain a list of files that debhelper reacts to, but notes that debputy provides clarity in this regard.

Facial features linked to stereotypes and social class perception
A new study conducted by the University of Glasgow has identified specific facial features that drive perceptions of social class standing and how these relate to stereotypes. The research focused on what makes someone appear to be of a higher or lower social class and how these appearances are linked to perceptions of competence, warmth, dominance, and trustworthiness. The study found that faces perceived as poor exhibited wider, shorter, and flatter features with downturned mouths and darker complexions, while faces perceived as rich were narrower and longer with upturned mouths and lighter complexions. These findings highlight the biases and consequences of social class stereotypes in society.

Extreme metal guitar skill linked to intrasexual competition, not mating success
New research suggests that extreme metal guitar skills are linked to intrasexual competition among male heterosexual guitar players, rather than mating success. The study challenges traditional notions of artistic displays in human courtship and social status. The researchers conducted an online survey with 44 heterosexual male guitarists who were fans of metal music. They found that the time spent playing guitar chords was linked to a higher desire for casual sex, but did not necessarily translate into a higher number of sexual partners. The speed of guitar playing was a significant predictor of intrasexual competition, indicating that guitarists who perceive themselves as playing faster than their peers tend to have higher levels of competitiveness. The study suggests that guitar playing in extreme metal music may be more about asserting dominance and status among male peers, rather than directly influencing mating success. However, the study has limitations due to its small sample size and focus on a niche music genre. Future studies should aim for a larger sample size and consider professional extreme metal guitarists.

Passenger flight flying over Pacific reaches 822 MPH in jet stream
China Airlines Flight 5116 achieved a speed of 822 mph as it flew across the Pacific Ocean, potentially breaking records for passenger travel. The flight, departing from Taipei, arrived in Los Angeles over an hour early due to strong tailwinds from the Pacific jet stream, which was supercharged by the El Niño climate pattern. While official records for commercial flight speeds are not kept, a recent article mentioned that a British Air Boeing 747 set a record of 825 mph in February 2020. Other flights, including China Airlines Flight 6, also experienced high speeds due to the swift winds. The jet stream winds even allowed the planes to surpass the speed of sound. The fast jet stream was caused by the absence of land masses or topography to slow it down, as well as temperature differences fueled by the El Niño climate pattern.

Hell is other people: performance management at Big Tech
The author discusses the controversial topic of performance management in big tech companies. They argue that the belief that these companies want a cutthroat environment is not true, as there is no incentive to fire mediocre staff in rapidly growing companies. The real reason for performance management is the employees' desire for fairness. The author explains how Google introduced a peer-based system for performance evaluation, which spread to other tech companies. However, the benefits of this system did not materialize, as providing honest feedback is seen as a social risk and most employees only put minimal effort into reviews. Managers are then tasked with interpreting the feedback for firings, promotions, and bonuses. The author concludes that the perception of this process is not necessarily better than the previous manager-based system, creating grand conspiracy theories.

Two handy GDB breakpoint tricks
The author of this web content shares two handy tricks for working with GDB breakpoints. The first trick involves using alternative definitions for the assert macro in C implementations to improve its behavior under debuggers. These alternative definitions immediately halt the program directly on the defect and optionally allow the program to continue through the defect. The second trick involves using named positions to set breakpoints in GDB. By temporarily naming a line number in the source code, the author is able to set breakpoints that adapt to program changes. The author also mentions using assembly labels and the dprintf function for debugging purposes.
Nearly 25,000 tech workers were laid off in the first weeks of 2024.Why is that?
In the first weeks of 2024, nearly 25,000 tech workers have been laid off by major tech companies such as Meta, Amazon, Microsoft, Google, TikTok, and Salesforce. Despite the fact that these companies are profitable and have ample cash reserves, they continue to shed jobs. Experts believe that the layoffs are driven by a "herding effect" in the tech industry, where companies see layoffs as a way to boost their stock prices. Additionally, smaller tech startups are facing cash shortages and struggling to secure funding, leading to workforce reductions. The layoff trend is also seen as a way to satisfy investors and maintain cost discipline. The phenomenon of companies imitating each other's layoffs has been referred to as "copycat layoffs" and is seen as a form of social contagion.
