The Pony programming language's standard library includes a networking package that functions adequately for simple TCP servers or clients but presents significant limitations when building more complex systems. These constraints become evident when attempting to implement advanced features like real protocol logic, backpressure control, or upgrading TLS mid-connection. The author, who had similar experiences at Wallaroo, explains that they created a new library called "lori" after forking the standard library's TCP code due to these constraints. The standard library's networking uses

Robert Smith discusses Fabrice Bellard's formula for calculating the nth hexadecimal digit of \(\pi\) without needing the previous digits. This method, known as Bellard's formula, is a significant improvement over the earlier Bailey-Borwein-Plouffe (BBP) formula, which led to the classification of these methodologies as BBP-type formulas. Over the years, many such formulas have been developed, with Bailey providing a technique to discover new ones through integer-relation algorithms. Smith conducted

Last month, a significant upgrade was completed for a client’s application, addressing two main issues: the outdated Rails 2.3 LTS and Ruby 2.5, and a lengthy test suite that took 40 minutes to run, hindering code merges and feedback loops. The upgrade upgraded the app to Rails 8.1.1 and Ruby 3.4.7, which led to an impressive reduction in test suite runtime from 40 minutes to about 4 minutes. The application

AI has significantly reduced the cost of producing superficial software that appears functional, leading to a common misconception that simply creating an app equates to comprehensive software engineering. Many viral posts showcase individuals claiming to have built apps without any coding experience, celebrating the creation moment while neglecting the complexities of operating and maintaining functioning systems. This phenomenon is likened to a viral video where creators make a model Bugatti out of clay; it looks like a Bugatti but lacks the engineering necessary for its performance. This illustrates

The author, a long-time fan of Heroku, praises its pioneering role in platform as a service, particularly highlighting the ease of deployment through "git push heroku master." Heroku significantly shaped the deployment experience for many developers, allowing them to build production apps without the complexities of EC2 instances. However, on February 6, 2026, Heroku announced a shift to a sustaining engineering model, ceasing new features and enterprise contracts. For those looking to transition away from Heroku

In this installment of the GNU Emacs series, the author shifts focus from the historical context of Emacs, which emphasizes its nature as a Lisp interpreter within a text editor, to a broader system-design perspective. The post begins by referencing the first installment and provides a brief overview of Lisp for those unfamiliar with it. The author discusses their approach to understanding source code by examining general computation principles, illustrating with a simple example (3 + 4 = 7). They highlight how computational processes can be

The article discusses the complexities of time handling in software programming, a topic often met with apprehension by developers. While some suggest standard advice like "just use UTC," this can lead to bugs in programs requiring precise timekeeping or user-facing datetime interactions. It introduces two key concepts: "durations," which represent lengths of time (e.g., how long an event takes), and "instants," which mark specific points in time (e.g., the moment an event occurs). Absolute time refers to

The author, not a legal expert, discusses recent challenges in open source licensing, particularly involving the project "chardet," a Python character encoding detector. Originally licensed under LGPL, the project encountered difficulties due to the requirement of unanimous consent for relicensing, which is hard for legacy projects. Recently, the maintainers rewrote the codebase and released version 7.0.0 under the MIT license. However, the original author raised concerns about a potential GPL violation, arguing that modifications must adhere

The writer reflects on their experience with Vodafone, expressing gratitude for a unique message received that offered "free unlimited data and 999999 minutes" for five days. The author shares that their family shares a mobile phone through two SIM cards and typically receives promotions tied to monetary top-ups. This unexpected message stood out due to its unprompted nature and the typo in the minute offer. Despite the oddity, the writer confirms they did indeed receive the minutes, although they found they were limited in usage.

Richard Gatling envisioned a machine gun in 1861 that could allow one soldier to perform the duties of a hundred, reducing the need for large armies and minimizing exposure to battle and disease. In 1923, Hermann Oberth advanced the concept of space travel in his works, proposing various rocket technologies and human space exploration initiatives. This inspired the formation of the Verein für Raumschiffahrt (VfR) in 1927 in Germany, which rapidly grew and contributed to popular culture,

The article discusses the challenges of coordinating concurrent tasks using Python's asyncio, particularly when managing shared state under real concurrency pressure. Aaron Harper describes the shortcomings of asyncio.Event and asyncio.Condition, which initially seem close to providing a solution but fail to handle every scenario effectively. He outlines the need for a mechanism to wait for specific states in an async Python application, like draining pending requests during a connection shutdown, and critiques existing methods. Using a loop to check status works but is inefficient. Instead, asyncio.Event provides
