VGGT: Lightning-Fast 3D Scene Reconstruction from Images

Facebook Research introduces VGGT (Visual Geometry Grounded Transformer), a feed-forward neural network capable of inferring all key 3D attributes of a scene—extrinsic and intrinsic camera parameters, point maps, depth maps, and 3D point tracks—from one, a few, or hundreds of views in mere seconds. This user-friendly model, leveraging the power of Transformers, offers an interactive 3D visualization tool. Surprisingly, VGGT demonstrates impressive single-view reconstruction capabilities, achieving competitive results compared to state-of-the-art monocular methods, despite not being explicitly trained for this task.

Python Protocols: Static Duck Typing and the Evolution of Inheritance

2025-02-02
Python Protocols: Static Duck Typing and the Evolution of Inheritance

Python's inheritance mechanism has always been interesting. Traditionally, Python uses type-based inheritance, similar to Java. However, the flexibility of duck typing (implemented through magic methods) is limited. PEP 544 introduces Protocols, allowing the definition of structural subtyping, also known as static duck typing. By inheriting from the Protocol class, developers can declare a set of methods; any class implementing these methods will be considered an instance of that protocol. This solves the scalability issues of traditional duck typing, resulting in cleaner, more maintainable code.

TB Tilde: A Disruptive LLVM Alternative?

2025-01-24

Yasser's TB Tilde aims to replace LLVM, boasting superior compile speed and a smaller footprint. Early tests show its preprocessor is twice as fast as Clang's. TB Tilde uses a 'Sea of Nodes' IR, features a simple type system and thread-safe modules, supports JIT and AOT compilation, and even directly outputs linked executables. The project is actively under development, targeting March 2024 for Cuik compiler self-hosting on Windows, with optimizer improvements to follow.

The Snapchat Streak and the Half-Life of Status Games

This article explores how Snapchat's streak feature briefly became a potent social capital game and its eventual decline. The author analyzes the fragility of 'proof of work' mechanisms in social networks and how major platforms extend their lifecycles by adding new content formats. Weaknesses of tech giants like Apple and Google in building social features are discussed, along with examples of companies leveraging social dynamics for business growth. Finally, the author concludes that for true happiness, one shouldn't tie it to others' scoreboards.

Biomachining: Using Bacteria to Machine Metal

2025-01-28

Biomachining is a novel machining process employing lithotrophic bacteria, such as Thiobacillus ferrooxidans and Thiobacillus thiooxidans, to remove material from metal parts. These bacteria utilize the chemical energy from iron or copper oxidation to remove material from a metal surface when immersed in a culture fluid. Unlike traditional chemical or physical machining, biomachining offers a low material removal rate and a superior surface finish, making it ideal for micromachining. This process has been successfully used on pure iron and copper, and involves masking the areas not to be machined, similar to chemical milling. The process's depth is influenced by factors like stirring rate and temperature.

Pentagon Halts Army Contracts, Sending Shockwaves Through Defense Industry

Pentagon Halts Army Contracts, Sending Shockwaves Through Defense Industry

A freeze on new US Army contracts has thrown the defense industry into chaos and uncertainty. The move, stemming from a review of plans implemented under the Trump administration, lacks clear explanation regarding its scope and reasons. While the Army spokesperson claims contracting activities continue, internal documents and sources indicate a pause or review of all contracting actions except those directly tied to readiness, modernization, and personnel. The communication, delivered via email rather than formal memo, has left program managers confused about implementation. Industry fears this could be the start of a Pentagon-wide freeze, creating widespread anxiety about future projects.

Hackers Face Lawsuit After Exposing Polish Train Manufacturer's Manipulation

2024-12-27

The Chaos Computer Club (CCC) is raising funds for three hackers who revealed at the 37C3 conference how Polish rail vehicle manufacturer Newag manipulated its trains to be repairable only in its own workshops. Newag reacted with a 90s-style aggressive lawsuit, pursuing both criminal and civil charges. The legal costs have already reached €30,000. The CCC is calling for donations to cover legal and other expenses. The hackers' research did not involve any illegal replacement of train components. The CCC believes Newag's lawsuit aims to prevent future publications about these 'illegal instructions,' emphasizing that only the content teams decide who speaks at the congress. The 38C3 congress will continue reporting on this case.

Booting 5000 Erlang VMs on a 192-Core Ampere One Server

Underjord, a consultancy specializing in Elixir and Nerves, successfully ran 5000 Erlang virtual machines on a 192-core Ampere One server. Each VM runs a Linux IoT device using the Nerves framework. This was achieved using a new bootloader, little_loader, streamlining ARM64 QEMU VM booting and leveraging KVM acceleration. Challenges included compilation issues and memory optimization, but these were overcome by adjusting BEAM VM allocators, Erlang release modes, and Linux kernel parameters. Over 5000 VMs were successfully run, opening new possibilities for testing and development of the Nerves framework and potentially integrating into future Nerves tooling.

Database Mocks: More Trouble Than They're Worth?

Database Mocks: More Trouble Than They're Worth?

While tempting for their speed and simplicity, the author argues that using database mocks for testing ultimately causes more problems than they solve. A user creation example highlights the differences between mocking and testing against a real database. Real database testing reveals potential issues early on, such as unique constraint violations, default value handling, and performance bottlenecks, saving debugging time and reducing production risks. As applications evolve and schemas change, real database tests better handle new validations, data type modifications, and timestamp precision changes, ensuring code aligns with the actual database. The author suggests prioritizing real database testing for data access layers, while using it at the service layer to expose business logic interactions with data. Controllers, however, can mock service calls effectively. Balancing real database tests and mocks is key to building robust applications.

South Korean President Yoon Suk Yeol Impeached Over Martial Law Decree

South Korea's parliament impeached President Yoon Suk Yeol on Saturday over his controversial six-hour-long martial law declaration. The National Assembly voted 204-85 in favor of impeachment, suspending Yoon's powers and duties. Prime Minister Han Duck-soo assumed presidential authority. The Constitutional Court has 180 days to decide whether to remove Yoon from office; a new election would follow within 60 days if he is dismissed. The impeachment followed days of political turmoil and widespread protests, with public opinion overwhelmingly in favor of removing Yoon. While Yoon declared the martial law as a measure against the opposition, his actions are seen by many as an attempt to undermine democratic processes. The US and Japan expressed support for South Korea's democratic process.

Thailand cut power, fuel, and internet access to some border areas with Myanmar on Wednesday in an attempt to cripple scam syndicates operating there. These syndicates, according to a 2023 UN report, are suspected of entrapping hundreds of thousands in illegal online and telecom operations, generating billions annually. The move, overseen by Thai Interior Minister Anutin Charnvirakul, aims to protect Thailand's tourism sector and address safety concerns, particularly after the recent abduction and rescue of Chinese actor Wang Xing in Myanmar. However, reports indicate some scam centers continue operating using generators, raising questions about the effectiveness of the strategy.
