The Myth of the IO-Bound Rails App

2025-01-25

It's a common belief that Rails apps are inherently IO-bound, with the database being the primary performance bottleneck, making Ruby performance less critical. This post challenges that notion. While the database is indeed a scaling bottleneck, the author argues that this doesn't mean the application spends most of its time waiting for I/O. Analysis of YJIT performance improvements and common performance issues (like missing database indexes) suggests many Rails apps are actually CPU-bound. The post highlights confusion between CPU starvation and I/O wait, and emphasizes that choosing the right execution model (asynchronous, threaded, or process-based) depends on the app's I/O/CPU ratio. The author calls for attention to Ruby performance and points out opportunities for optimization within Rails itself.

Bloomberg Philanthropies Steps Up Again to Fill US Climate Commitment Funding Gap

Following the US government's second withdrawal from the Paris Agreement, Michael Bloomberg's Bloomberg Philanthropies announced it will fill the funding gap left by the federal government and ensure the US meets its reporting obligations under the UNFCCC. This isn't the first time: Bloomberg took similar action in 2017 after the Trump administration's withdrawal, working with states, cities, and businesses to maintain US emission reduction commitments. This action again highlights the crucial role of local governments, businesses, and philanthropy in addressing climate change in the absence of federal leadership.

Cheap AI Enables 'Stupid' Ideas: The Birth of Gongzilla

The author used ChatGPT's o1 and v0 functionalities to create a small game called Gongzilla in under an hour, without writing a single line of code, through multiple iterations. While the game itself isn't perfect, it showcases the possibilities of rapid prototyping and creative realization in the age of cheap AI. This post explores the ease of AI-assisted creation and the value of exploring 'stupid' ideas at low cost—even if those ideas ultimately aren't perfect, the fun of learning and creating is invaluable.

Bambu's Controversial 3D Printer Update: A Necessary Security Measure or a Path to Enshittification?

Bambu Lab, maker of popular 3D printers, implemented a new proprietary authentication system, sparking controversy. While presented as a security measure against remote hacks, users fear it could lead to restrictions on third-party tools and filaments, and potentially, subscription services. Bambu claims the update is optional and maintains local access, but inconsistencies in their statements and security vulnerabilities have eroded user trust. The company's response to concerns, including promises to keep a developer mode and not require subscriptions for current models, attempts to quell fears but skepticism remains.

Do Cookie-Free Analytics Really Need Cookie Banners?

2025-01-25

This article investigates whether so-called "privacy-aware analytics" tools, claiming to perform website analytics without cookies, truly avoid the need for cookie banners. Delving into EU privacy regulations, particularly the ePrivacy Directive, the author finds that even 'cookie-free' analytics might require consent due to accessing information on user devices (like the User-Agent), thus necessitating cookie banners. The author concludes that current technology struggles to completely circumvent EU data access requirements.

North Korean Hackers Extort US Companies After Stealing Source Code

The FBI issued a warning about North Korean hackers posing as IT workers to infiltrate US companies, steal source code, and extort ransoms. These hackers use various methods, including AI face-swapping technology, to conceal their identities. After gaining access, they copy code to personal accounts and threaten to leak information for ransom. The FBI advises companies to strengthen hiring processes, limit permissions, and monitor network traffic to prevent such attacks. A joint statement from the US, South Korea, and Japan revealed that North Korean state-sponsored hacking groups stole over $659 million in cryptocurrency in 2024.

C++26: Pack Indexing Simplifies Element Extraction

2025-01-24

While C++11 introduced parameter packs, extracting specific elements remained cumbersome. C++26, thanks to proposal P2662R3, introduces pack indexing, allowing direct access to pack elements using the subscript operator, e.g., `T...[0]` for the first element. This leads to cleaner, more readable code and improved compile-time performance. Although negative indexing and slicing aren't yet supported, the feature is already highly usable, significantly improving C++ development.

In 1980, three identical triplets, separated at birth and adopted into different families, unexpectedly reunited. Their story, however, wasn't a heartwarming tale of chance encounters. It revealed a sinister secret: they were unwitting participants in a clandestine psychological experiment designed to unravel the nature versus nurture debate. Researchers, seeking to understand the impact of genetics and environment on behavior, secretly observed the triplets' lives for years. The experiment, however, caused significant emotional distress, with one triplet tragically taking his own life. The ethical implications of this secret study sparked outrage and continue to raise serious questions about the boundaries of scientific research.
