Differentiable programming is gaining traction beyond machine learning, being applied in various fields such as computer graphics through techniques like differentiable rendering and physics. The concept revolves around derivatives, which measure how a function changes with infinitesimal perturbations in its input. While traditional calculus looks at derivatives in 1D, higher dimensions allow a more intuitive understanding, viewing derivatives as transformations of vectors from one space to another. For instance, in a function with two variables, the partial derivatives reflect how changes in

Stackademic is a learning platform aimed at providing free coding education to programmers, developers, coders, and engineers. The content discusses the CAP theorem, which highlights the trade-offs in distributed systems, particularly in the face of network partitions. Formulated by Eric Brewer, the theorem asserts that when a network partition occurs, a distributed system can only guarantee two out of the three key properties: Consistency (C), Availability (A), and Partition Tolerance (P). The article raises awareness about the importance

The narrator discusses their experience with a bike owned by a friend who bought it from a now-bankrupt company. The bike has an integrated light that requires an app to function, which is problematic given the company's closure and lack of customer support. The narrator uses a cheap external light instead, but it was stolen when parked improperly. To fix the issue, they decide to make the embedded light work again by soldering wires to it. They discovered an internal battery setup and connected it to a USB-C charging

The post discusses lessons learned from developing and maintaining large distributed systems, particularly regarding challenges that arise when scaling beyond a single container architecture. A key issue highlighted is the competition among multiple services for resources in a shared cache cluster, which can lead to significant debugging difficulties, especially when eviction policies result in key loss for one or more services. The impact of losing keys may vary between services, complicating the diagnosis of problems. Although it's easy to scale a cache cluster as a solution, the author prefers not to

The article expresses disappointment with Synology's decision to lock its upcoming 2025 Plus NAS models to using only its branded hard drives. The author notes that this marks a decline from earlier, more innovative hardware offerings. In 2021, Synology began restricting drives for new NAS units, particularly in the enterprise segment, which has made it harder to recommend their solutions compared to competitors like QNAP and iXsystems, who have advanced their technology with ZFS support and better hardware.

The content emphasizes the importance of feedback and details a method for building JavaScript views without frameworks such as React or Vue. Titled "Writing JavaScript Views the Hard Way," this approach aims to create maintainable and performant views while avoiding common pitfalls associated with low-level imperative code. The document suggests that this technique favors directness over abstraction, providing a structured way to develop views. It begins with a simple "hello world" example and outlines the components and exports of a view. The view's template

In April 2025, it was reported that issue 99108, opened in November 2022 on Python's GitHub repository, has been resolved. The issue highlighted the need for Python to adopt verified code for its hash-related infrastructure following a CVE in its SHA3 implementation. As a result, all hash and HMAC algorithms in Python are now provided by the verified cryptographic library HACL*, with 15,000 lines of verified C code included in Python's repository. This transition

The article discusses the concept of feature flagging in software deployment, highlighting its advantages over traditional methods. Feature flags allow developers to wrap new features or significant code changes in conditional statements, enabling them to deploy code that includes both critical bug fixes and new features without exposing the latter until they're ready. This approach mitigates the risks associated with deploying new capabilities, as developers can turn features on or off as needed, instead of rolling back entire releases that contain multiple updates. The author emphasizes the need to shift the

The content discusses the concept of lockless programming, which allows multiple threads to safely share changing data without the overhead of locks. While it seems beneficial, lockless programming is complex and can sometimes fail to deliver the expected advantages, particularly on platforms like Xbox 360. It emphasizes the need for a thorough understanding of the underlying hardware and compiler when using lockless techniques, as well as careful performance measurement to ensure they offer actual gains. The article suggests that simpler solutions, such as reducing the frequency of

Gottfried Leibniz, a 17th-century polymath known for inventing calculus, actuarial tables, and the mechanical calculator, aspired to create a "characteristica universalis," a perfect language that would encapsulate all scientific truths. He believed this language could simplify discovery to the level of crafting grammatically correct sentences, ensuring clarity and eliminating ambiguity. This dream parallels modern programming languages, which, while not embodying the entirety of knowledge, represent the binary system (also a Leib
