Anker Recalls 1 Million Power Banks: CT Scan Reveals Battery Defects

Anker recalled over one million PowerCore 10000 power banks due to lithium-ion battery overheating risks. Lumafield used industrial CT scanning to analyze recalled and non-recalled units, revealing variations in battery cell suppliers, connection methods, and gap sizes between positive and negative terminals. These variations could lead to short circuits and overheating. The newer model uses a single pouch cell, simplifying assembly and improving safety. This case highlights the complexity of battery supply chains and the importance of quality control, showcasing industrial CT scanning's role in ensuring product safety and improving quality.

Append-Only Programming: A Fun Experiment

2025-02-21

The author experimented with a new software development methodology called "append-only programming": all code resides in a single C file, new code is appended to the end, and editing existing code is forbidden. This forces programmers to define interfaces upfront, write small functions, and produces highly readable code. However, this approach is error-prone; if a function is erroneous, a corrected version must be appended, and all callers must be corrected, potentially requiring rewriting the entire program. The author experimented with a Lisp interpreter and found it tedious. Ultimately, the author concludes it's a fun challenge but not a practical software development method, suggesting improvements such as using header files or one file per function.

Clojure Accounting: Evolving from Script to Interactive Web App

2025-03-08

The author initially used a Clojure script for accounting, but as the number of transactions grew, maintenance and sharing became difficult. A simple script is easy to write but provides a poor user experience, while a complex web application offers a good experience but is expensive to develop. The author cleverly combined Clojure's features with a simple web application framework to create an interactive accounting system similar to a notebook. This system allows users to write Clojure code, view results in real-time, and modify accounting rules and data via simple UI elements. It also supports data persistence, version control, and collaborative editing, effectively addressing the shortcomings of the original script and improving user experience and efficiency.

Clojure Error Handling: No Silver Bullet, Only Choices

2024-12-14

Clojure offers a diverse range of error-handling approaches, with no single best practice. The article explores several methods: throwing native exceptions, using `ex-info` for data-carrying exceptions, returning error maps, and utilizing various libraries for more sophisticated error handling flows, such as the `anomalies` library or options like `pact` and `failjure`. The author emphasizes that the choice depends on the specific context and that a mix of approaches can coexist within a single project. Developers are empowered to select the most appropriate solution for their needs; Clojure embraces this freedom.

Schneier's 'Data and Goliath' Prediction: A Decade Later, Privacy Lost?

2025-02-17

Schneier's 'Data and Goliath' Prediction: A Decade Later, Privacy Lost?

A decade after Bruce Schneier's book, 'Data and Goliath,' warned about government and tech giants exploiting personal data, his predictions ring eerily true. Data harvesting continues, especially for AI model training, leaving personal privacy almost completely compromised. Schneier advocates for comprehensive privacy laws and regulation of mass surveillance, but this remains unlikely in the short term. While some regions have implemented regulations, surveillance capitalism and the power of tech monopolies hinder meaningful change. Individual efforts to protect privacy are largely ineffective, and even companies like Apple offer limited protection. Schneier remains cautiously optimistic about long-term privacy, but acknowledges a long road ahead.

Can Large Neural Networks Solve Robotics? Insights from CoRL 2023

2025-07-05

At CoRL 2023, a central debate emerged: can training large neural networks on massive datasets solve robotics? Proponents argued that the success of large models in computer vision and NLP suggests this approach is promising, citing initial results from Google DeepMind's RT-X and RT-2 as examples. They believe the ongoing advancements in data and compute power fuel this direction. However, critics pointed out the current scarcity of robotics data, the immense variability across robot embodiments and environments, and the prohibitive cost of collecting large-scale datasets. Furthermore, even achieving high accuracy might not translate to the 99.X% reliability needed for practical deployment. Some suggested combining classical control methods with learning, while others called for entirely new approaches. Ultimately, CoRL 2023 highlighted the opportunities and challenges in robotics, offering valuable insights for future research.

New LLM Jailbreak Exploits Models' Evaluation Skills

Researchers have discovered a novel LLM jailbreak technique, dubbed "Bad Likert Judge." This method leverages LLMs' ability to identify harmful content by prompting them to score such content and then requesting examples, thus generating outputs related to malware, illegal activities, harassment, and more. Tested on six state-of-the-art models across 1440 cases, the average success rate was 71.6%, reaching as high as 87.6%. The researchers recommend that maintainers of LLM applications utilize content filters to mitigate such attacks.

C++ Coroutines: A Deep Dive into Customization

2025-07-13

C++ coroutines aren't a ready-to-use library like `std::vector`; they're a specification defining customization points requiring implementation by library writers. Extending the function concept, they support suspend, resume, and destroy operations. The `co_await` keyword marks a coroutine, and `Task::promise_type` customizes behavior at call, return, suspend, and resume points. The `awaiter` and `awaitable` mechanisms handle suspension and resumption, enabling resumption when dependencies are ready, providing flexible asynchronous programming.

NoDB: Processing Payments Without a Database

NoDB: Processing Payments Without a Database

Alvaro Duran's "The Payments Engineer Playbook" introduces a revolutionary approach to payment system design: processing payments without a database. He argues that the prevalence of asynchronous programming stems from the assumption of database necessity. Using event sourcing, each step in the payment process is recorded as an event, not as a persistent state. These events are temporarily stored in memory, and the system reconstructs the payment status from the event stream, eliminating the need for persistent storage. This high-performance, high-reliability approach, inspired by high-frequency trading, allows for quick recovery from outages through hot backups. The article details this concept using a payment flow example and looks toward future applications in payment systems.

Negative Carbon Emission Acetylene Production: A Breakthrough Based on Barium Looping

2025-07-22

Traditional acetylene production relies on the energy-intensive calcium carbide method, producing significant carbon dioxide and waste slag. This study proposes a novel green acetylene production process based on barium looping, using barium carbide instead of calcium carbide as an intermediate. The research finds that barium carbide formation exhibits faster kinetics, lower formation temperature, and no carbon dioxide release. Lab-scale barium recovery experiments validate the feasibility of this process, achieving negative carbon emissions. This environmentally friendly process is easily scalable and promises to be a key chemical platform for sustainable development, offering new insights into carbon-to-chemicals conversion.

Azerbaijan Airlines Crash: Missile Accident Emerges as Probable Cause

An Azerbaijan Airlines Embraer 190 crashed near Aktau, Kazakhstan, killing 38 of the 67 people on board. Initial reports from the investigation suggest the plane may have been accidentally hit by an air-defense missile while approaching Grozny. Surviving passengers reported hearing an explosion and seeing shrapnel hit the plane. The incident bears resemblance to the 2014 downing of MH17, also suspected to involve a surface-to-air missile. While the Azerbaijani president attributed the crash to a weather-related course change, the possibility of a missile accident is under investigation.
