Ransomware's Weird Vulnerability: Virtual Keyboards as a Defense

2025-06-30

Security experts have discovered a peculiar vulnerability in nearly all ransomware strains: they refuse to install on Windows computers with virtual keyboards like Russian or Ukrainian already installed. This is because many malware strains originating from Eastern Europe include checks for specific countries (e.g., Russia, Ukraine) to avoid local law enforcement. While not foolproof, installing a virtual keyboard, such as a Russian one, offers a simple, additional security measure to reduce ransomware infection risk. This approach leverages the fact that many cybercriminals avoid targeting computers within their own countries to avoid investigation.

The $100 Hamburger: A Pilot's Excuse for a Flight

2025-06-14

The '$100 hamburger' is aviation slang for a short flight (under two hours) to a nearby airport, grabbing a bite at the airport restaurant, and returning home. The name originated from the approximate cost of operating a small plane like a Cessna 172 for such a trip. However, with rising fuel prices, the cost is now significantly higher. A similar concept, the 'Rotto Bun Run' in Perth, Australia, sees pilots flying to Rottnest Island for hot cross buns, now an annual charity event.

Thunderbolt 5: A Quantum Leap in Speed and Capability

Thunderbolt 5 has arrived in 2024, bringing a significant performance boost to laptops and monitors. Compared to Thunderbolt 4, Thunderbolt 5 boasts double the bandwidth (up to 120 Gbps), supports up to 8K displays, and offers up to 240W of charging power. This translates to faster file transfers, support for more powerful external GPUs and AI accelerators, and superior display capabilities. While Thunderbolt 5 ports and cables look similar to Thunderbolt 4, the performance gains are substantial. If you demand top-tier performance, Thunderbolt 5 is worth considering, but its current adoption is still limited, and prices are relatively high.

Golioth Investigates: A Cellular Connectivity Mystery

Golioth recently encountered a perplexing cellular connectivity issue: some devices using a specific vendor's chipset experienced connection failures after OTA firmware updates. Investigation revealed the problem stemmed from some NB-IoT networks not adhering to 3GPP specifications, causing the modem to fail to obtain DNS server addresses correctly. The Golioth team, by deeply analyzing 3GPP specifications, modem trace data, and network protocols, ultimately found a workaround, but also exposed the drawbacks of closed ecosystems and lack of transparency, calling for greater industry transparency to improve cellular connectivity reliability.

140,000-Year-Old Homo Erectus Discoveries Rewrite History of Sundaland

Archaeological finds off the coast of Java, Indonesia, are rewriting our understanding of Homo erectus. Fossil remains, including skull fragments, unearthed during dredging operations in the Madura Strait, reveal a surprisingly mobile Homo erectus population inhabiting Sundaland, a vast lowland area now submerged. The discoveries, including evidence of hunting and diverse dietary habits, challenge previous theories of isolated Javanese Homo erectus populations. The findings point to a rich ecosystem and suggest interaction with other hominin groups, painting a far more complex picture of early human life in Southeast Asia 140,000 years ago. This unique collection, spanning 36 vertebrate species, offers unprecedented insight into the region's past biodiversity.

From Hours to 360ms: Over-Engineering a Sudoku Solution

2025-02-08

The author tackles a Sudoku puzzle aiming for the highest possible GCD among the nine 9-digit numbers formed by the rows. Initial attempts using the Z3 solver failed to find a solution within hours. The author then employed several optimization strategies: mathematical analysis to reduce the search space, a BFS algorithm, and iterative improvements to the `is_good` function, transitioning from HashSet to bitset and finally leveraging SIMD for vectorized computation. Multithreading and refined thread synchronization reduced the solution time from hours to 360ms, achieving over 1600x speedup. While a hardcoded answer proved fastest, the article showcases how even seemingly simple arithmetic problems offer significant performance gains through meticulous algorithmic optimization.

A Tooth for an Eye: The Remarkable Success of OOKP Surgery

2025-09-14

Osteo-odonto-keratoprosthesis (OOKP), or "tooth-in-eye" surgery, offers a groundbreaking solution for patients with severe corneal damage. This procedure uses a patient's own tooth (or a donor tooth) to create a biocompatible corneal implant, restoring vision where other methods fail. While risks like laminar resorption and glaucoma exist, long-term studies show remarkable success rates. Pioneered by Italian ophthalmologist Professor Benedetto Strampelli in the 1960s, OOKP represents a significant advancement in ophthalmic surgery, providing a lifeline for those suffering from irreversible corneal damage.

How to Make PostgreSQL Ridiculously Slow?

This article challenges the reader to make PostgreSQL as slow as possible by tweaking parameters in the `postgresql.conf` file, without resorting to CPU throttling or index deletion. Through a series of carefully chosen adjustments, including drastically reducing the buffer cache size (`shared_buffers`), aggressively triggering autovacuum and analyze (`autovacuum_*` parameters), and configuring WAL (`wal_*` parameters) for maximal write frequency and I/O contention, the author manages to reduce PostgreSQL's TPS by over 7000 times, from 7000+ to below single digits, even under 0.1 TPS. The author details the rationale and impact of each parameter change and provides a reproducible configuration. This is a fascinating experiment showcasing the profound impact of database parameter tuning.

Germany Updates US Travel Advice After Citizens' Detainment

The German foreign ministry updated its travel advice for the US after three German citizens were denied entry and detained. The updated advice warns that even with an ESTA, entry isn't guaranteed, and minor visa overstays or false information can lead to arrest and deportation. While the ministry insists it's not a travel warning, the cases – including a US green card holder who was subjected to harsh interrogation and detention – highlight potential risks. One detainee, a tattoo artist, was held for over six weeks and allegedly placed in solitary confinement. The incidents serve as a cautionary tale for German travelers to the US, emphasizing the importance of accurate information and adherence to visa regulations.
