PureVPN Vulnerabilities: IPv6 Leaks and Firewall Reset

2025-09-17

A security researcher discovered two critical vulnerabilities in PureVPN's client. First, an IPv6 leak allows users to access the internet via IPv6 even when connected to the VPN, exposing their real IP address. Second, the VPN client resets the user's firewall (iptables) rules upon connection and doesn't restore them upon disconnection, leaving the system more vulnerable. The researcher reported these issues to PureVPN but has yet to receive a response. Use PureVPN with caution.

Cambridge Blockchain Network Sustainability Index: Bitcoin Mining Map Reveals Energy Consumption Patterns

2024-12-12

The Cambridge Centre for Alternative Finance (CCAF) released a mining map visualizing global Bitcoin mining energy consumption as part of the Cambridge Blockchain Network Sustainability Index. The map shows the share of Bitcoin mining hashrate by country and region, revealing a seasonal migration pattern of Chinese miners between ‘dry’ and ‘wet’ seasons to leverage cheaper hydropower. However, this migration pattern likely ended after the Chinese government crackdown on the mining industry in June 2021. The research is based on geolocation mining facility data collected in partnership with several Bitcoin mining pools and acknowledges contributions from BTC.com, Poolin, ViaBTC, and Foundry.

CERN Engineer Locks 1950s Pendulum Clock to Atomic Clock for Unprecedented Accuracy

2025-01-04

A CERN engineer acquired a vintage Elektročas HH3 pendulum clock from the 1950s, boasting an accuracy of 0.1 seconds per day. To push the limits further, he embarked on a project to synchronize it with CERN's cesium atomic clock. The innovative solution involved a Chain Controlled Oscillator (CCO) which subtly alters the pendulum's center of gravity, controlled by a Phase Locked Loop (PLL) to maintain synchronization. Tests demonstrated remarkable improvement in accuracy, even detecting the perturbation caused by the recent Turkey earthquake. This project showcases a blend of meticulous engineering, ingenious innovation, and a quest for extreme precision.

Governments Must Shift from Consuming Open Source to Sustaining It

Fifteen years ago, the author predicted a three-stage evolution for Open Source: volunteer-driven, commercially involved, and government-supported. Today, Open Source underpins critical global infrastructure, yet its maintenance relies on a small number of contributors, creating significant risk. This article calls for increased government investment in Open Source, urging a shift from mere consumption to active contribution. Solutions include stable funding, incentivizing contribution in government contracts, and adopting "Public Money, Public Code" policies to ensure long-term stability and security. This isn't just a technical issue, but a strategic necessity for national security and societal well-being.

Ski Rental Conundrum: A Randomized Algorithm for Optimal Cost

2025-08-03

This article tackles the classic ski rental problem, a fascinating example in online algorithms. The problem: a skier doesn't know how many days they'll ski; renting costs 1 unit per day, buying costs B units. The article details an optimal offline solution, then analyzes a simple online algorithm with a competitive ratio of 2. Crucially, it dives into a randomized algorithm using a continuous probability distribution to approximate the discrete problem, achieving an expected competitive ratio of approximately e/(e-1), significantly better than the simple approach. While not directly applicable in reality for single decisions, this algorithm offers a theoretically optimal strategy for scenarios involving many similar choices.

Microsoft Fabric: Outages, Misinformation, and a Lack of Transparency

Microsoft's Fabric data analytics platform suffered another major outage last week, lasting for hours across multiple continents. However, Microsoft's official status page consistently showed everything as normal, leading to user outrage. Reddit users relied on third-party tools to track the outage, revealing significant discrepancies between Microsoft's reports and the reality on the ground. The response time was far longer than the actual event duration. Worryingly, Microsoft's post-mortem reports were vague, downplaying the impact and even hiding the history of outages. The author questions Fabric's lack of a service-level agreement and refunds, suggesting that its current popularity stems primarily from user ignorance.

Obscura: A Next-Gen VPN Using 2-Party Relays and QUIC

Existing consumer VPNs suffer from significant trust and privacy issues, as VPN providers act as a man-in-the-middle, seeing both user personal info and browsing history. Obscura VPN solves this by using a 2-party relay architecture and a QUIC-based VPN protocol. The 2-party relay separates "who you are" from "what you do," ensuring that even if one relay is compromised, not all user information is leaked. QUIC disguises VPN traffic as HTTP/3 traffic, bypassing network filters and avoiding the performance degradation of TCP over TCP. Obscura partners with Mullvad as its exit node and open-sources its app's entire source code, aiming for an open and private internet.

Memory-Efficient C Structs: A Deep Dive

2025-07-31

This blog post explores techniques for optimizing C structs to minimize memory usage. Using a `Monster` struct as an example, the author demonstrates several optimization strategies. These include reordering members to reduce padding, removing redundant fields (e.g., inferring `is_alive` from `health`), using smaller integer types (like `uint8_t`, `uint16_t`), employing bitfields for booleans, and replacing strings with enums for monster names. These optimizations shrink the `Monster` struct from 96 bytes to a mere 20 bytes, significantly improving memory efficiency. The post also discusses trade-offs and potential issues like integer overflows.
