Debouncing Switches: It's More Complex Than You Think

2025-01-08

This article delves into the complexities of mechanical switch bouncing. The author conducted experiments on 18 different switch types, revealing bounce times ranging from nanoseconds to hundreds of milliseconds, significantly impacted by switch type and actuation method. The findings highlight the inadequacy of simple software debouncing techniques for all scenarios, emphasizing the need for context-specific hardware or software solutions. Analysis reveals that besides physical contact bounce, analog signal transitions within TTL logic levels contribute to logical bouncing. The results challenge assumptions about switch behavior and call for more robust debouncing strategies.

Apple Faces Class-Action Lawsuit Over 'Carbon Neutral' Apple Watches

Apple is facing a class-action lawsuit alleging misleading claims that certain Apple Watches are carbon neutral. Plaintiffs argue that Apple's reliance on questionable carbon offset projects, which didn't actually reduce greenhouse gas emissions, constitutes false advertising. The suit highlights the challenges of making sustainability promises through carbon offsets, with environmental advocates pushing for cleaner energy and more durable, repairable products. Apple maintains it significantly reduced Apple Watch emissions and invests in nature-based carbon removal projects. However, the lawsuit questions the effectiveness of these projects, claiming they don't represent additional CO2 reduction. This case underscores the challenges companies face in environmental responsibility and growing consumer scrutiny of sustainability claims.

Zenobē's 300MWh Battery Project: Powering Scotland's Green Energy Transition

Zenobē, a UK-based energy company, is constructing a massive 300MW/600MWh battery storage project, Blackhillock, in Scotland. This will be Scotland's largest battery storage facility to date, representing 32% of the country's current installed capacity. Funded by £101m in debt financing, the project will provide vital grid stability services, reducing CO2 emissions by approximately 2.6 million tonnes annually and saving consumers over £170 million over 15 years. Blackhillock will also have the capacity to power over 3.1 million homes for two hours. Zenobē is a leading player in the UK EV bus sector, operating over 2,000 electric vehicles globally.

White House Hints at Using Gold Reserves to Buy Bitcoin

A senior White House official hinted at the possibility of the U.S. using its gold reserves to acquire more Bitcoin. Bo Hines, executive director of the President’s Council of Advisers on Digital Assets, suggested this could be a budget-neutral way to increase Bitcoin reserves. He referenced the Bitcoin Act of 2025, proposing the US acquire 1 million Bitcoin over five years, funded by selling Federal Reserve gold certificates. President Trump also voiced his commitment to making the US a leading Bitcoin power.

Why I Ditched Clojure for Common Lisp

2025-01-12

After seven years with Clojure, a programmer switched to Common Lisp due to frustrations with slow startup times and difficulties creating native executables. Key factors in his decision included the need for fast, standalone executables, Vim compatibility, cross-platform support, robust multithreading, and a vibrant community with a rich ecosystem. Common Lisp ultimately won out due to its mature tooling, powerful CLOS and Conditions system, and fast runtime.

Passive Investing's Rise: Is the Myth of Market Efficiency Broken?

Passive Investing's Rise: Is the Myth of Market Efficiency Broken?

Recent market volatility has sparked questions about market efficiency. A new study suggests the rise of passive investing has led to slower reactions by active managers to price discrepancies, amplifying the impact of individual trades. The growing dominance of index funds has decreased market sensitivity to price changes, potentially leading to increased volatility, reduced capital allocation efficiency, and even market failure. While the study's conclusions remain debated, it raises concerns about the potential risks of passive investing, particularly its impact on large-cap stocks.

Automattic Hit with Class-Action Lawsuit: A WordPress Power Play?

A class-action lawsuit has been filed against Automattic and its CEO, Matt Mullenweg, by cybersecurity expert Ryan Keller on behalf of thousands of WP Engine customers. The suit alleges Automattic abused its control over WordPress.org, cutting off WP Engine's access to crucial services, causing disruptions, security risks, and financial losses. While Automattic claims its actions were to protect WordPress's long-term interests, Keller argues it was a calculated move to cripple a competitor, characterizing it as an abuse of the open-source internet architecture. The case highlights a trademark dispute and questions the governance of WordPress, raising concerns about the power wielded by a single entity over a significant portion of the internet. The legal battle promises to be a significant development in the ongoing discussion about open source sustainability and the potential for abuse of dominant positions in the technology sector.

The Curious Case of the Public Domain Jaws Poster

The Curious Case of the Public Domain Jaws Poster

Celebrating the 50th anniversary of Jaws, a surprising fact emerges: due to a quirk of copyright law, the iconic shark painting from the movie poster is in the public domain. Initially rejected for resembling a "vagina with teeth," the artwork underwent revisions before becoming a classic. However, the lack of a copyright notice upon its 1975 publication inadvertently forfeited the image to the public domain, leaving artist Roger Kastel to unsuccessfully fight for copyright recognition years later and missing out on millions in royalties. The original painting's whereabouts remain a mystery, adding another layer to this fascinating tale of copyright and public domain, sparking discussion on artist rights and the commons.

Let Users Help Solve Their Own Transit Problems: Beyond Algorithmic Route Planning

The author criticizes current map apps for relying solely on algorithms to plan public transit routes, neglecting user needs and expertise. He proposes allowing users to customize route options, such as specifying particular bus route combinations, and including these in route planning comparisons. This mirrors the "report spam" and "not spam" functions of email filters, improving algorithms through user feedback. Despite privacy concerns, user participation could enhance route accuracy and user satisfaction, ultimately improving algorithms. The ability for users to add their own route combinations, even without sharing data, would be a significant improvement.
