The Inevitable Borrow Checker in Inko: A Trade-off Between Stack Allocation and Compile-Time Checks

2025-02-07

The Inko language designer explores optimal solutions for stack allocation and borrow checking. By default, Inko types are heap-allocated, offering flexibility but incurring performance overhead. To improve performance, an `inline` modifier is introduced to support stack allocation, but this brings new challenges: how to handle borrowing and move semantics while guaranteeing memory safety. The article explores several solutions, including allowing field assignments, introducing unique types, and escape analysis, ultimately concluding that compile-time borrow checking is the best approach, but its implementation complexity is high and it won't be implemented in the short term. Currently, Inko still uses a strategy that does not allow reassignment of inline type fields.

curl Gets a Major Update: Partial File Reading Support

The upcoming curl 8.12.0 release introduces exciting new functionality: partial file reading. Users can now leverage a new variable system to extract specific byte ranges from files and use them within curl command lines. This adds significant flexibility to how curl handles files, allowing for tasks like extracting the beginning of a file as a username or a section in the middle for a POST body. This significantly expands curl's capabilities, empowering users with a more robust command-line tool.

11 Million Strikers: A Phased Approach to the General Strike

2025-02-01

The General Strike is planned in three phases. Phase 1 (0-6 million signatures): Building a broad network of participants by connecting with organizations and individuals already taking action. Phase 2 (6-10 million signatures): Focusing on concrete demands, setting strike dates and event plans, and holding meetings to gather diverse perspectives. Phase 3 (10-11 million signatures): Finalizing demands, preparing for Strike Day, distributing funds, and conducting final events. The goal is to unite 11 million strikers to fight for racial, economic, gender, and environmental justice.

Trump's Tariffs Crash US Postal Traffic: An 80% Plunge

Trump's Tariffs Crash US Postal Traffic: An 80% Plunge

The Trump administration's abolishment of the de minimis exemption on small packages entering the US, effective August 29th, has caused a dramatic 80%+ drop in postal traffic. This policy change, eliminating duty-free entry for items under $800, left 88 global postal operators partially or fully suspending parcel shipments to the US. The Universal Postal Union (UPU) cites insufficient preparation time for operators to adapt to the new rules and collect duties, leading to major operational disruptions. The UPU is working on a technical solution to restore mail flow to the US.

Python Meta-Circular Interpreter: Implementing a Python Interpreter in Python

2024-12-18

This article demonstrates how to create a Python meta-circular interpreter (MCI) using Python itself. An MCI is an interpreter written in the language it interprets, allowing implementation of a subset or superset of the host language. The author details the MCI's implementation, covering parsing Python source code, building an Abstract Syntax Tree (AST), traversing the AST and executing statements, and crucial concepts like scoping, symbol tables, and handling control flow statements (e.g., while loops and if statements). This example provides a deep understanding of interpreter mechanics and showcases how to leverage Python's AST module and built-in functions to build more complex interpreters.

macOS Permission Pop-Up Vulnerability: TCC, Who?

A recently patched macOS vulnerability, CVE-2025-31250, allowed applications to spoof system permission pop-ups, tricking users into granting unauthorized access. Attackers exploited a flaw in Apple Events and the Transparency, Consent, and Control (TCC) system, separating the application displayed in the pop-up from the application actually receiving permissions. This vulnerability leveraged a logic error in the TCC daemon's handling of Apple Events permission requests, bypassing the need to create fake apps or override Dock shortcuts. The vulnerability has been patched, but highlights the complexity and potential risks in system permission management.

The Death of Microsoft: How Google, Ajax, and Apple Killed a Giant

2025-02-04

In 2007, the author realized Microsoft was no longer the fearsome software giant it once was. The rise of Google, the emergence of web-based Ajax technology, the proliferation of broadband internet, and Apple's resurgence all contributed to Microsoft's decline. While still profitable, Microsoft lost its dominance, its closed strategy and slow response to new technologies costing it the opportunities of the Web 2.0 era. The author argues that Microsoft's 'death' wasn't sudden but a result of multiple factors, its biggest weakness being its clinging to the traditional desktop software model and failure to embrace the new technologies and business models of the internet age.

Hugo: My Static Site Generator Nightmare

I used to love Hugo, a static site generator, for its speed, simplicity, and ease of use. However, with continuous updates, it's become increasingly complex and has repeatedly broken backward compatibility. My recent attempt to write a blog post resulted in Hugo updates causing my site build to fail, costing me hours of troubleshooting. I don't care about Hugo's internals; I just want a working blog. Therefore, I'm abandoning Hugo, seeking alternatives, and plan to compile an older, unchanging version myself.

OCR Challenge: Digitizing Saint-Simon's Memoirs

2024-12-17

The author spent several weeks using OCR to digitize a late 19th-century edition of the 18th-century French memoirs, *Les Mémoires de Saint-Simon*. This 45-volume behemoth, containing over 3 million words, is available online as images, but is difficult to read. The goal was to create a readable, searchable, and copyable text version. Challenges included poor image quality and parsing different page zones (headers, main text, margin comments, footnotes, etc.). Google Vision API was used for OCR, with a Python program processing the results to identify and separate text from different areas. While LLMs failed to reliably handle footnote references, the author improved the program and incorporated manual review, resulting in the release of the first volume.

1.2 Million-Year-Old Ice Core Retrieved from Antarctica

An international team of scientists has achieved a groundbreaking feat by drilling nearly 2 miles (2.8 kilometers) into the Antarctic bedrock, retrieving one of the oldest ice cores ever discovered—at least 1.2 million years old. The Beyond EPICA project, coordinated by Italy, involved four years of drilling in average temperatures of -35°C (-25.6°F). Analysis of this ancient ice is expected to reveal crucial information about Earth's atmospheric and climate evolution, shedding light on Ice Age cycles and the impact of atmospheric carbon on climate change. This discovery provides invaluable data for understanding and addressing the current climate crisis.

TrailBase: A Blazing Fast Lightweight Database

2025-02-04

TrailBase, a lightweight database, combines a low-overhead language, a fast HTTP server, and a lightweight relational SQL database. Benchmarks show TrailBase inserting 100k records over 20 times faster than SupaBase, 10 times faster than PocketBase, and even slightly faster than in-process vanilla SQLite. While SupaBase offers more features, its memory footprint is roughly 50 times larger than TrailBase's. TrailBase boasts sub-millisecond read latencies, comparable to Redis, but operates on primary data, not a cache. Its JavaScript performance is also exceptional, with its V8 engine outperforming PocketBase's goja engine by a factor of 40. In short, TrailBase is incredibly fast and resource-efficient, but real-world testing is crucial.

Y2K Scare: The Millennium Bug That Never Bit

In 1999, the Y2K problem, or millennium bug, sparked global panic. Older computer systems used only two digits to represent the year, leading to fears that at the turn of the millennium, systems would misinterpret '00' as 1900, causing widespread chaos. The Clinton administration called Y2K preparations 'the single largest technology management challenge in history.' Citizens stockpiled food, generators, and even weapons, fearing blackouts, medical equipment failures, and societal breakdown. Ultimately, the world transitioned to 2000 without major incident, highlighting the anxieties surrounding the unknown and the extensive preparations undertaken. The event served as a reminder of the interdependence of technology and societal stability.
