Recently, Suga observed a strange trend where new users were signing up but not engaging with the platform, leaving accounts inactive. The usernames were unusual, resembling random strings, prompting further investigation. This led to the discovery of subscription bombing, a tactic where bots sign up a victim's email on multiple sites, overwhelming their inbox with cluttered emails. The primary intent is not to access these accounts but to distract the victim while the attacker commits fraud, such as resetting bank passwords or making unauthorized purchases. Initially

The author, Shubham Raizada, reflects on their journey through various programming languages—Java, Go, Rust, and back to Java—and highlights the recurring theme of garbage collection (GC). They express a need to understand GC better, particularly its effects on performance and latency. This led them to explore foundational papers on garbage collection, particularly McCarthy's 1960 paper on Lisp, which introduced the mark-and-sweep method, and Wilson's 1992 survey organizing subsequent techniques into a taxonomy

The content discusses various techniques for concealing email addresses from spammers, emphasizing the importance of using multiple methods in combination for enhanced protection. Key points include: 1. **Basic Techniques**: While HTML entities are often easily decoded by harvesters, they can still deter many basic ones. 2. **Placement**: Hiding email addresses in unconventional locations can be effective, although the address is still in plain text. 3. **Accessibility**: Techniques should cater to users with screen readers. 4.

The recent accidental leak of Claude Code’s source code has sparked extensive discussion in the tech community. The author shares five observations that focus more on the implications of the leak rather than the leak itself. They note that the quality of a product’s code does not necessarily determine its success, particularly in the software industry, as evidenced by the sudden success of Claude Code and Cursor despite concerns about coding practices among developers. This suggests that even if the code is poorly written, a product can still thrive if it meets

This week, two significant announcements in quantum computing (QC) emerged. The first, from Caltech, demonstrated a method for achieving quantum fault-tolerance with reduced overhead using high-rate codes, applicable to architectures like neutral atoms and potentially trapped ions. The second announcement, from Google, revealed a lower-overhead implementation of Shor's algorithm capable of breaking 256-bit elliptic curve cryptography. Notably, Google opted to disclose this result through a cryptographic zero-knowledge proof to prevent attackers from

The content discusses the introduction of a new C++ backend for `ocamlc`, which enhances the previous C implementation used by the runtime and FFI. It provides an example program that calculates prime numbers up to a user-defined limit and details how to compile the program into C++ code, resulting in a file named `primes.cpp`. The piece notes that C++ lacks mutable state support, making the OCaml standard library inaccessible due to its reliance on mutation. To work around this, a portion

Raspberry Pi has announced significant price increases for all models equipped with LPDDR4 RAM, including a new 3GB RAM Pi 4 priced at $83.75, and a 16GB Pi 5 now costing $299.99. This trend reflects wider issues in the hobbyist single-board computer (SBC) market, which is struggling due to rising DRAM costs, making new boards increasingly expensive and less accessible for hobbyists. Many vendors, except for Radxa, have reduced

The author has recently made small improvements to their website, such as using a Rust crate compiled to WASM to properly justify Arabic poetry. They recognized the need for OpenGraph metadata when sharing articles on social media and temporarily chose a torn Syrian flag image, which isn't always relevant. The author proposed WASM plugins in Zola forums, although they await approval. The article reflects their thought process as they experiment, noting challenges in passing complex data between the Host and Plugin due to memory management issues. They emphasize

The content discusses a fast CBOR (Concise Binary Object Representation) encoding and decoding library for mruby, highlighting its benefits, performance metrics, and usage guidelines. CBOR is a compact and efficient data format, comparable to JSON and msgpack. The library reportedly offers encoding speeds approximately 30% faster than msgpack and up to 3 times faster selective decoding than simdjson. It incorporates security features like depth limits and deterministic behavior. Users can integrate it into their mruby project by modifying

NASA is providing live updates for the Artemis II test flight, with broadcast coverage available on NASA+, Amazon Prime, and YouTube. Key developments include the successful deployment of the Orion spacecraft’s solar array wings, which are essential for power generation during the mission. Each solar wing has 15,000 solar cells and extends the Orion's wingspan to about 63 feet. Upcoming milestones include the perigee raise maneuver and apogee raise burn, which will adjust Orion's orbit for deep space operations

The article by Itamar Turner-Trauring discusses methods for processing infinite streams of events, particularly when the length of the stream is unknown. Since storing all data isn't feasible, a random sampling approach can yield useful insights. It uses the example of a performance profiler, which analyzes the call stack of running code to identify slow areas. The article introduces reservoir sampling, a method for selecting random samples from such a stream. It explains how to pick a single sample and then extends the concept to selecting multiple samples

The cost of software development has significantly decreased, with recent advancements enabling the rebuilding of major projects quickly using AI coding agents. Following this trend, a team has undertaken the ambitious task of completely rebuilding WordPress, the CMS that powers over 40% of the internet, which is now 24 years old. The new CMS, named EmDash, is designed to be a modern successor to WordPress, written entirely in TypeScript and optimized for serverless environments while still allowing deployment on personal hardware or various

In his July 2008 article, Fredrik Lundh discusses recursive-descent parsing in Python, highlighting its simplicity and efficiency when parsing prefix-heavy grammars. He notes, however, that such parsers can become inefficient with expression syntaxes that include multiple operators of varying precedence. A naive implementation may require excessive recursion for parsing simple expressions. Lundh references Vaughan Pratt's 1970s improvement, known as Top-down Operator Precedence, which enhances recursive-descent parsing by associating semantics with tokens

Throttling is a technique used by frontend developers to control the frequency of function calls in response to high-frequency events like resizing and scrolling. It limits how often a signal can trigger work, which is beneficial for performance but poses a risk of missing important events, especially the final state after an event ends. This can result in stale app states or missed analytics data. The content emphasizes that while throttling limits invocation frequency during events, it does not ensure a final invocation after these events cease, leading to

The article discusses the internal workings of a replicated Key-Value (KV) server built on the RAFT protocol, following the completion of labs 3 and 4 from the MIT 6.584 course. The main goal of this implementation is to create a fault-tolerant system composed of multiple KV server nodes that can continue to serve clients even if some nodes fail. RAFT ensures strong consistency and can tolerate the failure of `f` nodes in a system of `2 * f +
