Designing Lenses with PyTorch: A Differentiable Optics Library

2025-03-21

Torch Lens Maker is an open-source Python library for differentiable geometric optics built on PyTorch. Its ambitious goal is to design complex real-world optical systems (lenses, mirrors) using modern computing and cutting-edge numerical optimization. The core is differentiable geometric optics: 3D collision detection and optical laws implemented in PyTorch. By cleverly treating optical elements as layers in a neural network, and leveraging PyTorch's auto-differentiation and optimization algorithms, designing lenses becomes surprisingly similar to training a neural network, unlocking the power of modern machine learning tools. The project is early-stage and the author is seeking funding to continue development.

Crafting an HTML Builder DSL in Lua: A Clever Approach

This article demonstrates building a Domain Specific Language (DSL) in Lua for generating HTML. The author cleverly leverages Lua's syntactic features, such as optional parentheses and function chaining, along with function environments and metatables, to create a concise and elegant HTML generation solution. A custom `__index` metamethod dynamically generates HTML tag functions, and an `append_all` function efficiently concatenates strings. The result is a fully functional HTML builder DSL, significantly improving code readability and development efficiency. The article also highlights the crucial importance of HTML escaping to prevent security vulnerabilities.

Rare Kimsuky Leak Reveals Tactics and Infrastructure of North Korean-Linked APT

A rare security incident involving a data breach attributed to a North Korean-affiliated actor, dubbed “Kim,” offers unprecedented insights into Kimsuky (APT43) tactics, techniques, and infrastructure. The group focuses on credential-centric intrusions targeting South Korean and Taiwanese networks, blending Chinese-language tooling, infrastructure, and potential logistical support. The “Kim” dump, containing bash histories, phishing domains, OCR workflows, compiled stagers, and rootkit evidence, reveals a hybrid operation between DPRK attribution and Chinese resource utilization. The leaked data includes malware development, OCR parsing of Korean PKI and VPN documents, and reconnaissance targeting Taiwanese government and academic institutions. Analysts uncovered an advanced Linux rootkit employing syscall hooking and stealth persistence. The incident highlights the evolving capabilities of North Korean threat actors and their potential connections to Chinese resources.

A Decade of JavaScript Frameworks: From Chaos to Consolidation?

A Decade of JavaScript Frameworks: From Chaos to Consolidation?

A decade on, JavaScript frameworks have evolved from small, lightweight options to large, feature-rich ecosystems. The rise of server-side rendering and improvements in browser APIs have enabled code sharing between client and server, leading to the emergence of 'meta-frameworks'. This post explores the strengths and weaknesses of popular frameworks like Next.js and React Router, advocating for simple, maintainable technology choices like a traditional React SPA with an Express API backend, or carefully chosen combinations depending on project needs (e.g., Fastify or NestJS for backend APIs, coupled with meta-frameworks for the UI). While framework choice remains abundant, the author suggests that recent improvements in the JavaScript ecosystem have significantly improved the developer experience.

Gallup's latest data reveals a decade low in US employee engagement in 2024, with only 31% of employees reporting engagement—mirroring 2014 levels. Actively disengaged employees also reached 17%, matching 2014 figures. A two-percentage-point drop since 2023 highlights growing employee detachment, especially among those under 35. Key factors contributing to this decline include unclear expectations, lack of care, and limited development opportunities. Gallup advises leaders to focus on workplace culture, defining organizational purpose and values, and developing managers who can inspire and engage employees.
