TypeScript: Object Parameters vs. Individual Parameters

2025-04-17

When writing functions in TypeScript, you can pass arguments individually or group them into an object. This article argues that object parameters are superior. Individual parameters lead to ambiguity and maintainability issues as the number of parameters increases. Object parameters, like `{firstName: "John", lastName: "Doe", age: 28, isActive: true}`, offer clarity, self-documentation, and leverage TypeScript's autocompletion and type safety features.

T-Mobile's Five-Year Price Guarantee: The Fine Print

T-Mobile's Five-Year Price Guarantee: The Fine Print

T-Mobile's new Experience plans boast a five-year price guarantee, but there's a catch. While the base plan price remains unchanged, taxes and fees are excluded from this guarantee. These fees include regulatory charges, interconnection fees from other carriers, and network leasing costs, all of which T-Mobile can adjust. This means the actual cost could still increase, making the 'guarantee' more of a promise on the base price, not the final bill.

Trump Tariffs Cause a Dramatic Drop in US Port Imports

President Trump's tariffs have led to a drastic decline in US port imports, with Seattle's port experiencing an unusual lack of container ships. This has raised concerns about supply chain disruptions, rising prices, and job losses. The Ports of Los Angeles and Long Beach are facing similar issues, with imports down 35% year-on-year. Experts warn that the impact will ripple across the nation, starting with West Coast ports and spreading to other regions. While the administration is negotiating with China to potentially reduce tariffs, the outcome remains uncertain.

The Atari 1200XL, the third in Atari's 8-bit computer line, aimed to replace the increasingly expensive Atari 800 and compete with the Commodore 64. Featuring 64K RAM and a sleek 1980s design, its $800 price tag and incompatibility with popular software like Letter Perfect doomed it to a short lifespan, discontinued after only six months. Despite this, its excellent keyboard and fixable compatibility issues make it a sought-after collectible today, even retaining practical use.

GitHub PAT Leak: Attack Chain Widens

Security researchers at Wiz discovered that attackers exploited a vulnerability in reviewdog/action-setup@v1 to steal a GitHub Personal Access Token (PAT), leading to a wider security incident. This wasn't an isolated incident; several other GitHub Actions maintained by the same developer, including reviewdog/action-shellcheck, are potentially affected. While GitHub and reviewdog maintainers have patched the vulnerability, Wiz warns that if compromised actions remain in use and secrets aren't rotated, attackers could still exploit "tj-actions/changed-files" to launch a repeat attack.

eGPU: Extending eBPF to GPUs for Low-Overhead Dynamic Observability

2025-04-10

With the surge in GPU-accelerated workloads, existing monitoring tools often suffer from high overhead or invasiveness. eGPU innovatively extends eBPF to GPU kernels via runtime PTX injection, enabling low-overhead dynamic observability. By compiling eBPF bytecode into PTX and injecting it into running GPU kernels, eGPU allows for dynamic addition, modification, and removal of instrumentation without interrupting execution. This not only improves the efficiency of GPU performance analysis but also opens up possibilities for programmable GPU computing, runtime optimization, and GPU security.

Meta Whistleblower Accuses Zuckerberg of Prioritizing Power Over US National Security

Former Meta employee Sarah Wynn-Williams testified before a Senate Judiciary subcommittee, accusing Mark Zuckerberg of prioritizing power over US national security. She alleges that Zuckerberg, in an effort to curry favor with the Chinese government, compromised American interests by assisting in censorship and providing user data to the CCP. Wynn-Williams' testimony also details Meta's attempts to silence her and suppress her book, "Careless People," which details alleged dealings with the Chinese government and accusations of sexual harassment. Meta denies the accusations, calling them "divorced from reality and riddled with false claims." Lawmakers are demanding Zuckerberg testify before the committee.

AI Writes Code, AI Reviews It? Is That Silly?

Daksh, co-founder of Greptile, discovered that an AI code generation tool, Devin, was submitting more pull requests than any human engineer. This raises the intriguing question: should AI-generated code be reviewed by AI itself? While LLMs are stateless, each call is independent, this doesn't mean AI perfectly reviews its own code. AI-generated code, while boosting efficiency, may introduce bugs humans struggle to find. Research shows AI is more effective than humans at finding certain types of bugs, although its accuracy still needs improvement. Ultimately, the article argues that while not perfect, AI code review is more effective than humans at finding specific bug types introduced by AI itself.

Why Frameworks Are Evil: A Case for Libraries

This article delves into functional library design principles, focusing on composability and avoiding callbacks. The author argues that frameworks are difficult to compose, explore, and test, and restrict code structure. In contrast, libraries offer greater developer control, encourage interactive exploration, and support multiple layers of abstraction. Using a game engine example, the article demonstrates how asynchronous workflows and event-based programming can mitigate the drawbacks of callbacks. Examples like FsLab illustrate the composability of libraries. Ultimately, the author advocates for building composable, easily explorable libraries instead of rigid frameworks.

Published in 1797, *The Columbian Orator* profoundly impacted two giants of American history: Frederick Douglass and Abraham Lincoln. Compiled by Caleb Bingham, this rhetoric textbook featured selections ranging from ancient Greece to the British Parliament, its random arrangement designed to captivate students. It aided Douglass's rise as a powerful orator after escaping slavery and shaped Lincoln's early speaking style, becoming a staple in early American education. Once blacklisted in the South for its radical views on equality, *The Columbian Orator* continues to influence generations, remaining a classic for scholars and orators alike.

He highlights a two-decade long process involving a leadership shift and a crucial change in employee work ethic. Huffman admits Reddit's early idealism hindered its business operations, leading to low productivity. Returning as CEO in 2015, he emphasized the importance of hard work, shifting the company from idealism to a more pragmatic business approach. Reddit now boasts a $21 billion valuation, with Q1 revenue surging 61% year-over-year to $392.4 million. Its success stems from its unique community and its use as a search engine complement, navigating challenges posed by Google algorithm changes.
