Malicious NPM Packages Targeting Cursor.com Deployed by Snyk Researcher

A Snyk security researcher deployed several malicious NPM packages targeting Cursor.com, a popular AI coding company. These packages, named things like "cursor-retreival" and "cursor-always-local", collect system data and send it to an attacker-controlled server upon installation. The attack leverages dependency confusion, aiming to trick Cursor employees into installing these public packages. While the OpenSSF package analysis scanner flagged and reported these malicious packages, NPM hasn't yet marked them as such. This highlights limitations in software supply chain security tools and emphasizes the importance of careful NPM package installation.

Solved: The Sum-Free Sets Conjecture

2025-05-25

Solved: The Sum-Free Sets Conjecture

A seemingly simple mathematical problem—the sum-free sets conjecture—has baffled mathematicians for decades. The conjecture explores whether, within any set of integers, there exists a large subset where the sum of any two numbers in the subset is not also in the subset. In 1965, the renowned mathematician Paul Erdős posed the question, providing a lower bound. Despite many attempts to improve upon it, progress remained stagnant until February of this year, when Oxford graduate student Benjamin Bedert finally solved the problem, demonstrating that any set of integers contains a large sum-free subset, significantly larger than previously estimated. Bedert's proof cleverly combines techniques from diverse mathematical fields, offering new approaches to similar problems. This achievement is hailed as a major breakthrough in mathematics.

Massive Supply Chain Attack Compromises Hundreds of E-commerce Stores

Hundreds of e-commerce stores, including a $40 billion multinational, are running backdoored versions of popular software. Security firm Sansec discovered that attackers have been actively exploiting these backdoors since at least April 20th. Affected packages are from vendors including Tigren, Magesolution (MGS), Meetanshi, and Weltpixel, released between 2019 and 2022. Attackers compromised vendor servers to inject backdoors, gaining access to all customer stores and their visitors. The backdoor disguises itself as a license check, located in License.php or LicenseApi.php. E-commerce stores using software from these vendors are urged to check their security immediately.

The Surprising Geography of Vacation Homes in the US

An analysis of US Census data reveals fascinating patterns in the distribution of vacation homes across the country. Florida leads with over 800,000, followed by California and New York. However, as a percentage of total housing, New England states like Maine, Vermont, and New Hampshire boast the highest proportions, exceeding 15%. Vacation homes cluster heavily along coasts, near the Great Lakes, in New England, and parts of the West. Location correlates strongly with geographical amenities like beaches, lakes, mountains (and ski resorts), golf courses, and theme parks. Surprisingly, major cities have a disproportionately low percentage of vacation homes. The study also notes that vacation home growth lags behind overall economic growth, likely due to low construction productivity and restrictive zoning regulations.

1.5 Years of AI-Assisted Programming: Reflections and Lessons Learned

This post shares the author's 1.5-year experience using AI for programming. AI excels at repetitive coding tasks, refactoring, and simple projects, but struggles with complex problems and new development, often introducing errors and inefficient abstractions. CLI interfaces prove more effective than IDEs due to increased developer control. AI aids in design and writing, but 'vibe coding' (relying solely on AI-generated code) is discouraged, leading to significant technical debt and security vulnerabilities. The author concludes that the primary beneficiaries of AI aren't developers, but managers and clients, facilitating improved communication and collaboration. The future of AI in programming is bright, but companies shouldn't use it as an excuse for layoffs.

Trump Tariffs: The Impact on Tesla – Debunking the Myths

Trump Tariffs: The Impact on Tesla – Debunking the Myths

Despite the rosy outlook painted by some Tesla fans, the reality is that President Trump's tariffs on Mexico and Canada will negatively impact Tesla. Data reveals that Tesla sources over 20% of its parts from Mexico, with additional components coming from Canada. This means the recently delayed (again, for another month) tariffs will inevitably increase Tesla's production costs, affecting vehicle prices and profitability. Tesla's stock reaction to the tariff delay further underscores this impact. Elon Musk's close relationship with Trump, and his seeming inaction against the tariffs, adds a layer of complexity. The long-term effects may extend beyond mere cost increases, potentially damaging US business relationships with Canada and Mexico.

Unexpected Inconsistency in C# Records: A `with` Operator Gotcha

Unexpected Inconsistency in C# Records: A `with` Operator Gotcha

The author discovered an unexpected inconsistency when using C# records. When updating records containing derived data with the `with` operator, the derived data isn't recalculated, leading to inconsistencies. This stems from the `with` operator not calling the constructor but instead using a copy constructor to create a copy and then modify properties. Several solutions are proposed, including avoiding `with` on complex records, writing a Roslyn analyzer to detect the issue, using `Lazy` for deferred property computation, and requesting a language change. This post highlights a potential pitfall in C# records, cautioning developers about using the `with` operator, especially with derived data.

AI Code: From Vibrators to Pacemakers – How Far Can Our Trust in Code Go?

2025-07-10

The author uses the code of a vibrator and a pacemaker as examples to discuss the issue of code security and trust in the age of AI. The simple vibrator program and the complex pacemaker program are surprisingly similar in structure, but the latter concerns life safety and requires strict review and certification. The author questions whether, even if AI can write better code than humans in the future, we can fully trust AI-generated code, especially for programs related to life safety, such as a car's braking system. The author argues that radical transparency, including open code, specifications, and processes, is key to building trust, but the correctness of the code alone is not enough; comprehensive system understanding and security measures are also needed.

Android System Font Iterator Bug Hunt: A Tale of Hidden Symbols

2025-06-02

This blog post recounts a surprisingly lengthy bug fix. Android defines different API levels, with some symbols only available from a specific version. Firefox for Android (Fenix) uses `ASystemFontIterator_open`, available only from API 29. For backward compatibility, Fenix uses `__ANDROID_UNAVAILABLE_SYMBOLS_ARE_WEAK__` and `__builtin_available` for compile-time and runtime checks. However, Firefox's build system defaults to hidden visibility (`-fvisibility=hidden`), causing the weak symbol `ASystemFontIterator_open` to become undefined in the shared library, leading to crashes. The fix was a simple change to temporarily alter the default visibility when including Android system headers.

The Placebo Effect: Stronger Than You Think

The 18th-century London street sale of Perkins Tractors (metal rods for pain relief) showcased the early form of the placebo effect. Today, placebos come in various forms, from oral pills to injections, and their effectiveness varies depending on the form. Studies show that intra-articular placebo injections are more effective at pain relief than topical placebos, which are in turn more effective than oral placebos. Surprisingly, the difference in effectiveness between intra-articular and oral placebos sometimes exceeds the difference between active pain relief drugs and oral placebos. Furthermore, doctor demeanor and patient age also impact placebo effectiveness. The significantly increased placebo effectiveness in the US in recent years has led to some drugs failing approval due to reduced relative efficacy, a phenomenon worthy of further investigation.
