8 Years of Sleep-Induced Reboots: Decoding a Dell Inspiron Firmware Bug

2025-09-22

For eight years, the author's Dell Inspiron 5567 randomly rebooted when put to sleep, across multiple operating systems. A deep dive into the firmware's source code revealed the culprit: the Southbridge's SPTS method. This method prematurely sent the sleep command before properly setting the sleep state, causing the reboots. The solution involved reordering code within SPTS to ensure the sleep state was correctly set before triggering the sleep. The article details the debugging process and explores the intricacies of ACPI sleep states.

MinIO's Controversial Community Edition Changes Spark Outrage

MinIO, a popular open-source object storage solution, has removed key web-based management features from its community edition, prompting backlash from users. The free version now requires users to rely on command-line tools or upgrade to a paid plan. This decision, likened by some to 'enshittification,' has led many to explore alternatives like SeaweedFS, Garage, and Zenko. MinIO maintains that the changes are necessary to sustain the project's development.

Building Databases on Object Storage: Taming High Latency

Building Databases on Object Storage: Taming High Latency

This post delves into common challenges, particularly high latency, encountered when building databases on object storage like AWS S3. The author highlights that object storage latency often follows a lognormal distribution, with long tail latencies significantly impacting performance. To mitigate this, three strategies are proposed: request hedging (sending multiple requests and taking the fastest response), latency-based retrying (retrying after exceeding a threshold), and using different endpoints. Furthermore, the post advocates for caching and horizontal scaling to further optimize performance. Caching reduces the number of object storage accesses, while horizontal scaling leverages the range read API of object storage to boost throughput. The author emphasizes that the optimal strategy depends on the specific application and cost considerations. A Rust program demonstrating these strategies is also mentioned.

ESP32 Bluetooth Controller 'Backdoor': A False Alarm?

2025-03-11

Recent concerns have emerged regarding a potential "backdoor" or "undocumented features" in the ESP32 Bluetooth controller. Espressif has responded, stating that the so-called "undocumented HCI commands" are solely for debugging purposes and do not pose a security threat. These commands assist in debugging (e.g., read/write RAM, memory-mapped flash read, send/receive packets), and don't play an active role in standard Bluetooth host stack (like NimBLE or Bluedroid) HCI communication. In ESP32, the controller and host run on the same MCU, communicating via a virtual HCI layer. Any code accessing this layer must execute on the ESP32 with full privileges. Therefore, unless the application itself has vulnerabilities, these undocumented commands cannot be exploited. Espressif will provide a software patch to remove access to these debug commands and will document all vendor-specific HCI commands for greater transparency.

The Cat Symphony: A Tale of Friendship and Art

An Austrian painter created his *Katzensymphonie* to celebrate violinist Joseph Joachim's appointment as director of Berlin's Hochschule für Musik. The painting's origins lie in 'Die Schwarzen Katzen,' a society founded in 1862 by contralto Amalie Joachim and friends, including Johannes Brahms, Julius Otto Grimm, and Clara Schumann. Membership was based on a 'cat-like' appreciation for fine things and friendship, with the constitution even detailing punishments for un-cat-like behavior. The painting and the society's story reveal a deep friendship and shared artistic passion.

Supreme Court Rules Broadband Isn't Telecom; Net Neutrality Fight Continues

A 2024 Supreme Court ruling empowered courts to block agency interpretations of federal statutes, overturning a 2016 FCC decision under the Obama administration. The court decided broadband is classified as an "information service." Groups like Free Press are foregoing an appeal, focusing instead on Congress, state legislatures, and other courts to fight for internet affordability and openness. While the 6th Circuit's decision was flawed, alternative approaches are deemed more effective. Net neutrality could still reach the Supreme Court through other cases, and California's net neutrality law remains in effect.

Amazon River Dolphins Communicate Through 'Pee Fountains'

New research reveals Amazon River dolphins (Inia geoffrensis) communicate using a peculiar behavior: aerial urination. Male dolphins eject urine into the air, and nearby males frequently approach these 'pee fountains,' suggesting the urine conveys information about social status or physical condition. This adds to the growing body of evidence showing the diverse ways animals use urine to communicate, from primates using it for individual recognition and mate finding, to fish and crustaceans using it to signal size and aggression. The study highlights the underappreciated role of olfactory communication in the animal kingdom.

Efficiently Cleaning Up Logically Deleted Files in Object Storage: Lessons from WarpStream

This post details the author's experience in efficiently cleaning up logically deleted files in object storage when building distributed systems. Using bucket policies or synchronous deletion directly both have flaws: bucket policies can't handle complex systems with varying data retention needs, while synchronous deletion can lead to orphaned files. The author compares delayed queues and asynchronous reconciliation, ultimately adopting a hybrid approach: introducing an "optimistic deletion queue" in WarpStream Agents, combined with asynchronous reconciliation, for efficient and cost-effective file cleanup, effectively avoiding orphaned files. This approach leverages system characteristics and considers fault tolerance and disaster recovery.

Mexico's Indigenous Language Renaissance: A Race Against Time

Mexico is actively working to preserve its rich indigenous language heritage. Faced with the dominance of Spanish and English, 68 officially recognized indigenous languages, including Mayan and Nahuatl, spoken by nearly 7 million people, are in decline. To counter this, the Mexican government has launched an initiative to offer indigenous language classes nationwide, with some areas even implementing fully bilingual curriculums. Mayan language education in Yucatán is showing significant progress, with 35,000 students now having the option to study Yucatec Maya. Mexico City will also begin offering Nahuatl classes in 78 schools in the coming weeks. This initiative aims not only at language preservation but also at revitalizing indigenous culture by recognizing the importance of Mexico's pre-Hispanic heritage. However, challenges remain, including limited resources and dialect diversity. Discrimination, stemming from the legacy of Spanish colonization and ongoing social prejudice, is a serious concern. The fight for indigenous languages in Mexico is not just about preserving words; it's about reclaiming identity, dignity, and a place in a society that has long marginalized its native peoples.
