The writer is frustrated with corporate culture and feels overwhelmed by excessive management and busywork, leading to burnout. They're being let go from their job and see it as a chance for a fresh start.
The user discusses various topics including evolution, infectious diseases, radiation, and human preferences, concluding that many problems can be solved with technology and societal cooperation. They also touch on the importance of appreciating the complexities and quirks of life, including the safety of air travel and the benefits of carbon sequestration in disposable plastic.
The author discusses improving I/O performance by using io_uring and kqueue APIs to submit requests to the kernel for readiness and completion events, allowing for batching and amortizing system call overhead. A central dispatcher is built to handle I/O requests and completion events, providing a simple API for scheduling I/O and passing callbacks for event completion.
The user discovered four indicators in Chocolate Quake netcode: TURTLE, DISC, RAM, and NET, which were likely intended for developers and map designers to diagnose performance issues. These indicators show up on screen when the framerate drops below 10fps, HDD access is slow, the engine evicts surfaces from cache, or a client hasn't received packets from the server in 300ms.
The user reminisces about their elementary school days and shares their experience with a chess-enthusiast teacher who created a large chess board in the schoolyard. They then discuss the history of the Domain Name System (DNS) and how it has evolved over time, including the failed attempt to implement a hierarchical naming system in the US with RFC 1480.
As a team grows, feedback becomes harder to process due to the lack of personal relationships and context. Leaders must build systems and processes to filter and synthesize feedback at scale.
The user discusses the pain points of eventual consistency in database architectures, including operations costs and weird behavior, and how it can cause problems in application code. They explain how their team invested in making all reads strongly consistent in Aurora DSQL, which avoids these issues and allows for more effective scaling and easier application development.
HN community members share gratitude for the site's enduring quality and meaningful discussions despite some decline in discourse. They appreciate the community's refuge from online absurdity and thank founders for creating this space.
The kernel isn't a process—it's the system. It serves user processes, reacts to context, and enforces separation and control.

The user built a DIY NAS server, the DIY NAS: 2026 Edition, with a Topton N22 motherboard, JONSBO N4 case, and TrueNAS 25.10.0.1 operating system, aiming to provide a capable homelab machine with a small footprint. The build features six drive bays, an integrated low-power CPU, and a focus on power efficiency, with the user considering auctioning off the build on eBay due to rising component prices.
Researchers at Tufts University created a fluid silk material that shoots from a needle, solidifies mid-air, and can lift items far heavier than itself. The breakthrough was achieved by mixing silk fibroin with dopamine, which sped up the solidification process, allowing for instant adhesion and controlled shooting.
Mixpanel detected a smishing campaign on November 8th, 2025, and took steps to contain and secure impacted user accounts. Affected customers were proactively communicated with, while unaffected customers received no action required notification.
We formalize a subset of the x86 architecture in Coq, using dependent types and notation to give it a concise and readable semantics. The model includes a concrete representation of bits, bytes, and memory, and supports conventional assembly code syntax inside Coq.
The VanDersarl brothers built a Blériot XI in 1911 using a modified automobile engine and learned to fly it. After a century, the restored plane was registered as an experimental airplane and flew again in 2012.
The author explains how a graphics project uses a distance field to generate shadows, and implements a technique called ray marching to improve performance. The technique involves advancing along a ray by a distance proportional to the distance from the closest shape.
The ZZ9000 is a multifunctional Zorro card for the Amiga with a powerful FPGA, 2 ARM Cortex-A9 cores, and DDR3 memory. It offers features like a flickerfixer, coprocessor, network card, and USB interfaces, supporting up to 1920x1080 FHD resolution.
The user is using the Claude model to extract information from a text. The model is extracting a person's name, age, and occupation.
Researchers in Delhi found that playing calming music to patients under general anaesthesia reduced their need for anaesthetic drugs and improved recovery. The study suggests that music can help patients wake up more quickly and clearly.
The theory of GPL propagation to AI models, where GPL code in training data propagates to the model, remains an indeterminate problem with ongoing lawsuits and no clear judicial precedent. The theory could be ratified by the judiciary if the plaintiffs win in ongoing lawsuits, but it has serious detrimental effects and many experts argue against it.
