Should Go 2 Ditch the `context` Package?

2025-01-21

Go's `context` package, while solving the goroutine cancellation problem, does so at the cost of readability and maintainability, spreading like a virus throughout codebases. The author argues that `context` is overly complex, has too many interface methods, and `ctx.Value` presents numerous issues and is inefficient. They propose that Go 2 should directly address goroutine cancellation at the language level, providing a simpler, more efficient, and less intrusive solution.

Mysterious Light in Brussels Mausoleum: Coincidence or Design?

Mysterious Light in Brussels Mausoleum: Coincidence or Design?

Every June 21st at midday, a shaft of light pierces the roof of a mausoleum in Brussels' Laeken Cemetery, creating a heart of light. It's unclear whether this was intentional. The tomb's occupants died in 1916 and 1919, with the mausoleum built in 1920. The designer is little known, and plans don't mention the light. The article also features a poem inscribed on the monument of Sir Lawrence Tanfield (d. 1625), expressing his wife's love and grief.

The End of the Reading Revolution? The Decline of Reading and the Crisis of Democracy in the Smartphone Age

The End of the Reading Revolution? The Decline of Reading and the Crisis of Democracy in the Smartphone Age

This article explores the reversal of the reading revolution. The 18th-century reading revolution democratized knowledge, fostering reason and democracy. However, the advent of the smartphone age has led to a sharp decline in reading, with people's attention captured by fragmented information and social media, leading to a decline in critical thinking and cognitive abilities. This not only leads to the loss of knowledge but also threatens the foundation of democratic systems, as democracies require citizens to possess sufficient knowledge and critical thinking skills. The article warns that this trend toward a post-literate society could lead to social regression, returning to a pre-printing era of authoritarianism and superstition.

Distributed Database Replication using SWIM and BadgerDB

This article details a distributed database replication scheme leveraging the SWIM protocol and BadgerDB's incremental backup feature. Using Hashicorp's memberlist package and its TCP Push/Pull mechanism, nodes periodically compute their local state and send it to other nodes. Remote nodes merge the remote state with their local state, triggering the replication process. Node state is defined as the set of last known versions of other nodes. Upon receiving state, a node sends HTTP requests to the remote node, concurrently syncing incremental backups of auth, config, and log databases, thus achieving actual replication.

Heat Pump Sales Surge: A Closer Look at the Reality

Heat Pump Sales Surge: A Closer Look at the Reality

While heat pump shipments have surpassed gas furnaces, data reveals this hasn't significantly altered US home heating practices. Many installations are in new constructions or non-furnace systems, not replacements for existing gas furnaces. Analyzing AHRI shipment data and EIA's Residential Energy Consumption Survey, the author argues that heat pump retrofits in existing homes remain minimal, and large-scale transformation is far from achieved. Positive headlines may mask slow progress; sustained effort and policy support are crucial.

Rediscovering Piranesi's Perspective Trick: A Forgotten Artistic Technique

Rediscovering Piranesi's Perspective Trick: A Forgotten Artistic Technique

This article delves into the unique perspective technique employed by 18th-century artist Giovanni Battista Piranesi. Unlike traditional perspective, Piranesi's trick uses a near-large, far-small ratio when depicting a series of similar objects, rather than true perspective convergence. This technique, while violating perspective rules, enhances image readability and comprehension. The article analyzes the mathematical principles of this technique and, through comparison with traditional perspective, demonstrates its potential applications in image processing and mapmaking. The author even developed an algorithm to apply this technique to image editing software, offering a fresh perspective on image manipulation.

Danish Metal Detecting Hobbyists Unearth Ancient Treasures, Rewriting History

A Danish engineer's casual metal detecting hobby led to an extraordinary discovery: a hoard of 1,500-year-old gold artifacts, including an amulet inscribed with "He is Odin's man." This inscription, the oldest known written mention of Odin, pushes back the known history of his worship by 150 years. Denmark's unique approach to metal detecting, allowing hobbyists to search and turn over finds, has revolutionized archaeological research, resulting in a wealth of discoveries far exceeding those of neighboring countries.

The Chilling Effect: How Fear is Silencing America

America is experiencing an unprecedented chilling effect on free speech. The President and his allies are using political pressure, threats, and dismissals to silence critics, targeting nonprofits, media outlets, and even academics. This fear permeates various sectors, from academia to media, leading to widespread self-censorship. The situation eerily resembles Putin's Russia, although the US boasts a more independent judiciary, media, and civil society. However, these institutions are under attack, and their willingness to act is being tested. Only by more people bravely stepping up to defend fundamental freedoms can this unsettling trend be reversed.

Tortoise and Hare: Finding Balance in Productivity

2025-05-02

Using the analogy of a childhood ride-on lawnmower lacking blades, the author explores the 'Tortoise and Hare' approach to life. He contrasts the high-efficiency 'Hare Mode' with the slower, more contemplative 'Tortoise Mode,' arguing that these aren't opposing forces but complementary ones. Reflecting on the anxiety and exhaustion following a period of 'Hare Mode' success, the author emphasizes the importance of slow thinking and deep work, advocating for a flexible shift between the two modes, much like regulating a wood-burning stove. The balance between high efficiency and slow living is crucial for sustainable progress, avoiding burnout or stagnation.

Tesla Found Partially Liable in Autopilot Wrongful Death Case

A Miami federal jury has found Tesla partially liable in a 2019 wrongful death lawsuit involving its Autopilot system. George McGee, driving a Tesla Model S with Autopilot engaged, ran a stop sign and crashed into a couple, killing Naibel Benavides and severely injuring Dillon Angulo. While Tesla argued McGee was solely responsible, the jury determined Tesla bore one-third of the liability for selling a defective vehicle, awarding plaintiffs $129 million in compensatory damages and $200 million in punitive damages. This marks the first time a jury has found Tesla liable in a wrongful death case involving Autopilot.

AI Boom Creates Hard Drive Shortage

The rise of generative AI has created a surge in demand for nearline hard drives, but hard drive manufacturers haven't kept up, leading to a severe shortage. Western Digital has announced price increases across its entire hard drive portfolio, with lead times exceeding a year. This price increase is also impacting the SSD market, with enterprise-grade SSDs likely to see price hikes. While manufacturers are developing more economical nearline SSDs, the storage crunch is expected to continue in the short term, making now a potentially good time for consumers to purchase storage.

A Cornell University study reveals that AI writing assistants may homogenize writing styles toward Western norms, particularly impacting billions of users in the Global South. The study found that Indian and American users' writing became more similar when using an AI assistant, primarily at the expense of Indian writing styles. While both groups experienced increased writing speed, Indians saw less productivity gain due to frequent correction of AI suggestions. The AI often suggested American foods and holidays, even replacing Indian celebrities with Western ones. Researchers term this 'AI colonialism,' urging tech companies to focus on cultural nuances for more inclusive AI tools.
