Rust: The wrong people are resigning:
The article discusses the author's experience with private online discussion spaces related to Rust and their disappointment in the recent drama surrounding ThePHD and JT resigning over RustConf. It highlights issues like a lack of resources, process, or manpower and suggests that the Rust project should communicate better for transparency. The author decides to leave the „in group“ and join the „out group“ in order to contribute as a competent critic using publicly available information.
The Mysterious 50 Ohm Impedance: Where It Came From and Why We Use It:
The concept of 50 Ohm impedance is crucial in RF/high-speed PCB design and is found across signaling standards, component datasheets, application notes, and design guidelines. The origin of the 50 Ohm standard can be traced back to the late 1920s/early 1930s, when engineers developed air-filled coaxial cables for radio transmitters that needed high power transfer, voltage, and low attenuation. The optimal impedance turned out to be a compromise between minimizing losses, maximizing power transfer, and increasing voltage, resulting in 50 Ohms. This standard is used to measure S-parameters as signal integrity metrics in high-speed/RF systems.
The text provides a list of people who died in unusual or accidental circumstances. The circumstances include a man falling from a building and landing on a woman, a man accidentally stabbing himself, a writer falling and fracturing his skull, a man dying from a heart attack while mowing his lawn, a man dying after a wrestling match, a woman found dead in her bathtub, and a woman choking on a Bible during a sexual encounter.
the_incredible_cave_where_marburg_may_dwell.html:
The article discusses Kenya's Kitum Cave, which is known to be inhabited by bats, elephants, and insects.

Oberlandesgericht: Drohnenaufnahmen fallen nicht unter die Panoramafreiheit:
The OLG Hamm ruled that aerial drone images of artworks cannot be freely distributed, only ground-level perspectives are protected. The German Copyright Act and the EU Copyright Directive of 2001 do not extend panorama freedom to drone-captured aerial views of works of art. In a now published decision from April 27 (Case No: 4 U 247/21), the ruling states that such photos, videos, or paintings may not be freely reproduced, distributed, publicly displayed, or marketed. Privileged are only recordings and representations made from public ways, streets, or squares and depicting the view „as it appears to the general public“.
Android-Spyware: Legitime App nach einem Jahr verwanzt:
A trojanized app called iRecorder – Screen Recorder, with over 50,000 installations, was discovered by Eset IT security researchers. Initially harmless, it was found to be infected with malicious functions in August 2022. The malware steals files with specific extensions, pointing to a spying campaign. Google removed the app from Google Play, but it may still be available on other app stores and .apk download archives. The malicious code was based on the open-source remote-access toolkit AhMyth.
Chronic stress can inflame the gut — now scientists know why:
New research has found that psychological stress can worsen gut inflammation caused by certain bowel diseases. The study, published in Cell, traces a sequence from chemical cues produced in the brain to immune cells in the gut, highlighting how chronic stress can trigger physical distress and potentially influencing treatment effectiveness for inflammatory bowel disease (IBD). Managing stress levels might have a significant impact on the response to IBD treatments. The findings could also lead to new pharmacological treatments targeting the signalling pathway between the brain and the gut.
The article discusses the discovery of the oldest musical instrument, a 60,000-year-old Neanderthal flute found in Divje Babe cave near Cerkno, Slovenia. Made from a cave bear's thighbone with four pierced holes, it is evidence of the Neanderthals having developed music and artistic expression similar to modern humans. This find challenges previous assumptions about their cultural sophistication and supports the idea that they were fully-developed spiritual beings.
Hacker News - Bias and Credibility:

For best brainpower, avoid snacking on foods with processed carbs:
A study conducted by researchers at the University of Montpellier found that consuming high amounts of processed carbs such as sugar and white bread can lead to insulin resistance, which in turn affects cognitive abilities including thinking, memory, and learning. The findings reveal a decline in performance in cognitive tests for young adults who had a habit of eating processed carbs, particularly during snack times. This study suggests that continuous consumption of these foods may negatively impact brain function even when the individual is still young and healthy.
This article argues against using third-party VPN providers as they are merely glorified proxies that can see and manipulate user traffic. It suggests that most VPN providers log users' activity and advises users to set up their own virtual private networks (VPNs) instead, through services such as Streisand or manually. The article emphasizes the importance of understanding VPN limitations and prioritizing privacy and security over convenience.
Naming Conventions with Underscores in Python:

Social Media and Youth Mental Health — Current Priorities of the U.S. Surgeon General:
Up to 95% of young people aged 13-17 use social media platforms, with nearly two-thirds using it daily and a third using it almost constantly. However, this heavy usage can pose mental health concerns for these users, with an increased risk of depression and anxiety symptoms in those who spend more than three hours a day on social media. Despite gaps in our understanding of the impacts of social media, the current situation warrants swift action to protect children and adolescents from harm. Actions for various groups such as parents, tech companies, policymakers, researchers, and young people themselves are proposed to mitigate the risks associated with social media usage.

Why Do Recipe Writers Lie About How Long It Takes To Caramelize Onions?:
The article discusses the misconception of caramelizing onions within recipes, claiming that they should only take a few minutes to cook. However, in reality, it takes around 45-50 minutes for onions to caramelize properly on medium heat. The author experiments with different techniques and amounts of time to achieve proper caramelization, debunking the quick methods proposed by various recipes. The main point of the article is that recipe writers should be honest about the time it takes to properly prepare ingredients like caramelized onions, rather than giving misleading estimates in order to save time or make a dish seem quicker and easier to cook.
Ask HN: How to move from dev role to management/team lead role?:

They ask for suggestions on resources, such as courses, videos, or lectures that could help them in this journey.
Black holes might be defects in spacetime:
A team of theoretical physicists has discovered a new class of object called topological solitons, which appear as defects in the fabric of space-time and are stable without matter or forces. These solitons mimic the appearance of black holes when observed from a distance, but their unique properties distinguish them from traditional black holes, as they lack event horizons and can be interacted with physically. The discovery of these objects may help researchers test string theory and find alternatives to Einstein's general theory of relativity.

Hoarding is a comfort behavior that reduces discomfort and anxiety by acquiring items and maintaining an emotional attachment to them. It has three main components: acquiring additional things, inability to take care of the collected items realistically, and not being able to part with the collected items. Hoarding can cause practical problems but often involves a denial of these issues. Emotionally, hoarders may believe each acquired item has a greater use in the future than its present one and may have extreme guilt associated with disposing of objects. Helping hoarders requires addressing both practical cleanup needs and emotional aspects that contribute to their behavior.
