Go Protobuf's New Opaque API Improves Performance and Safety

2024-12-16

The Go team released a new Opaque API for Go Protobuf, coexisting with the existing Open Struct API. This new API decouples generated code from its underlying memory representation, leading to performance improvements, reduced memory allocations, and enabling optimizations like lazy decoding. By hiding struct fields and accessing them only through accessor methods, it prevents pointer-related bugs and accidental sharing. Migration involves enabling the Hybrid API, using the `open2opaque` tool, and then switching to the Opaque API. The existing Open Struct API remains supported.

Wild: A Blazing-Fast Linker for Linux

Wild is a linker designed for speed in iterative development. While incremental linking isn't yet implemented, it's already impressively fast. For production builds, more mature linkers like GNU ld or LLD are recommended. However, for development, Wild significantly speeds up build times, especially on x86-64 Linux systems. It supports statically and dynamically linked executables and shared objects, and has been tested with many popular crates from crates.io. Currently under development are features like incremental linking, support for other architectures, and more linker flags.

Revisiting Barricelli's Cellular Automata: Spontaneous Generation of Life

2025-01-07

This article explores the work of Nils Aall Barricelli, who pioneered cellular automata 15 years before John Conway. Barricelli's 'symbioorganisms' model, in a finite, circular 1D space, simulates the movement and interaction of different elements through simple rules of collision elimination, positional replication, and mutation. The simulations reveal that even with simple rules, stable periodic patterns spontaneously emerge, resembling the spontaneous generation of life. The author delves into the stability of these patterns and proposes combining early universe simulations with simulations of abiogenesis to find more efficient ways to explore life's origins.

WASM Program Bypasses node:wasi Filesystem Sandbox

WASM Program Bypasses node:wasi Filesystem Sandbox

This project demonstrates a proof-of-concept showcasing how a WASM program can bypass the preopens directory restriction in node:wasi to access files outside the sandbox. Normally, WASM programs are limited to accessing pre-opened directories. However, by cleverly using symbolic links to replace files at a precise moment and running an external process, this limitation can be circumvented. This is not a practical security vulnerability in node:wasi, but rather a potential edge case. The project highlights that one shouldn't rely on node:wasi to completely prevent malicious code from accessing external files.

SBCL Compiler Optimization: Speeding Up Compilation of (lambda () nil)

The SBCL compiler received a significant optimization that dramatically improves the compilation speed of empty functions like `(lambda () nil)`. Previously, compilation generated many redundant functions. This optimization identifies and handles these special cases, directly returning a predefined empty function, thus avoiding unnecessary computation and significantly increasing compilation speed. This improvement is especially effective when dealing with large amounts of code containing empty functions, reducing compilation time and boosting developer productivity.

Dissecting MrBeast: Algorithm-Driven Content Creation at its Finest

Blogger Kevin Munger reveals the secret behind YouTube megastar MrBeast's success: a maniacal obsession with YouTube's algorithm. It's not about superior production or inherent content quality, but precise manipulation of metrics like CTR, AVD, and AVP. MrBeast and his team meticulously optimize content to maximize these numbers, generating massive views and revenue. The article argues that MrBeast's 'success' isn't artistic, but a data-driven creation process, even tailoring team members' information intake ('information diet') to perfectly align with algorithmic preferences.

Vim: A Programming Language Beyond an Editor

2024-12-15

Vim is more than just a text editor; it's a language for interacting with your computer. Its concise and efficient command structure is easy to learn and remember, and also easy for a computer to interpret. While Vim itself is powerful, its core strength lies in the fact that its mode has been integrated into almost every mainstream code editor, allowing developers to flexibly choose their preferred editor interface while retaining Vim's efficient command language. Therefore, NeoVim, as the most complete and consistent implementation of the Vim language, is valuable for providing this efficient editing language, not just the editor itself.

Serverless Computing: Why Haven't We All Switched Yet?

2025-01-09

Despite the appealing value proposition of serverless computing (e.g., AWS Lambda)—pay-per-use, auto-scaling, and abstraction from infrastructure—widespread adoption remains slow. The author points to two primary reasons: the lessons learned from the challenging microservices migration, where many organizations struggled due to insufficient technical and organizational readiness; and the fact that serverless amplifies existing challenges of microservices, such as complexities in dependency injection and observability. A gradual adoption approach focusing on highly autonomous teams and suitable use cases (like AI and LLM integrations) is suggested as a more efficient strategy.

Medicare to Negotiate Prices for 15 Popular Drugs

Medicare to Negotiate Prices for 15 Popular Drugs

The Biden administration announced that 15 commonly used drugs, including Ozempic and Wegovy, will be included in Medicare's price negotiation program. This marks the first time the U.S. government will directly negotiate drug prices with manufacturers, and is expected to save taxpayers billions of dollars. While Ozempic and Wegovy have drawn scrutiny for their high costs, Medicare currently only covers them for diabetes treatment, not weight loss. The incoming Trump administration will decide whether to implement a proposed rule to cover these medications for obesity. This brings the total number of drugs subject to Medicare price negotiations to 25, covering a third of prescription drug spending. The pharmaceutical industry has sued over the program, but groups like the AARP say they will fight to uphold the law.

A Glimpse into OS/2's Built-in Virtualization

2024-12-17

This blog post explores the surprisingly advanced built-in virtualization capabilities of OS/2 2.1 from 1993. The author demonstrates OS/2's ability to load and execute disk images, much like modern hypervisors, by creating a simple VGA mode program and running it in DOSBox, QEMU, and OS/2's own virtual environment. OS/2 can even run images that aren't true bootable DOS floppies, using VMDISK to create an image file and running it in fullscreen or windowed mode within OS/2. This functionality, remarkable for 1993, is essentially a built-in QEMU, prompting the author to consider the further potential of OS/2's virtualization features.

Negotiating with Infringers: A Better Option for Creative Professionals

When a creative professional's copyright is infringed, litigation isn't the only option. This article's author, a lawyer, suggests considering negotiation with the infringer. Negotiation is quicker and cheaper than litigation and may yield benefits beyond monetary compensation, such as promotion and collaboration opportunities. The author points out that most infringements are not malicious but due to negligence. Through negotiation, adversaries can be transformed into collaborators, leading to long-term success. Of course, if negotiations fail, litigation remains a last resort.

Base-Rate Blindness: When Rare Events Surprise Us (and How AI Might Exploit It)

2025-01-26

This essay uses the astonishing feats of pickpocket Apollo Robbins to illustrate the concept of 'base-rate blindness'. The author argues that we underestimate the probability of rare events because we tend to ignore base rates – the prior probability of an event. Using personal anecdotes, like a surprising moose encounter in Colorado, and the academic world's underestimation of deception, the author shows how ignoring base rates can lead to dangerous consequences. The essay concludes with a provocative question: Are we base-rate blind to the potential risks of AI, distracted by the hype and pleas for regulation?
