Object-Oriented Python Enigma Machine Implementation

2025-01-25

This blog post details an object-oriented Python implementation of the Enigma cipher machine. Based on the description in 'The Code Book', the author models each component (rotors, plugboard, reflector, etc.) as a class, simulating the encryption/decryption process. This simplified implementation includes three rotors, a plugboard, and a reflector, omitting the ring setting. The author highlights the ease of simulating the Enigma machine in code compared to physically building one, underscoring the power of modern computing.

Serbia: A Digital Prison – State Surveillance and the Suppression of Civil Society

Serbia: A Digital Prison – State Surveillance and the Suppression of Civil Society

Amnesty International's report reveals Serbia's use of surveillance technology and digital repression to control and suppress civil society. The report details widespread use of spyware, including NSO Group's Pegasus and a newly disclosed domestically-produced Android spyware, NoviSpy, along with Cellebrite's UFED tools against environmental activists and protest leaders. This constitutes a serious human rights violation and attack on freedom of expression.

Programmer Focus Indicator: The Birth of FlowLight

2024-12-15

Inspired by a research paper on the impact of work interruptions, programmer Shae Erisson DIYed a system called FlowLight to indicate whether a programmer is in a focused "flow" state. The system monitors idle time in the Emacs editor; when the programmer is inactive for a period, an Adafruit MagTag board's LED changes color (green for idle, red for busy). Erisson also wrote an HTTP server in CircuitPython to remotely control the LED color and display status. While the system has room for improvement, such as more granular idle time monitoring and a more visually appealing display, it effectively helps programmers avoid interruptions and improve productivity.

The Illusion of Intelligence: AI, Interaction, and the Clever Hans Effect

2024-12-15
The Illusion of Intelligence: AI, Interaction, and the Clever Hans Effect

This paper explores the nature of intelligence in AI, particularly large language models (LLMs). It argues that the apparent intelligence of LLMs isn't due to independent reasoning but rather emerges from interaction with users. Drawing parallels between Socratic questioning, the Clever Hans effect, and iterative prompting of LLMs, the author demonstrates that intelligence is a relational phenomenon arising from collaboration, not isolated cognition. LLMs generate responses based on probabilistic relationships within their training data, responding to user prompts like Clever Hans responded to his handler's cues. The value of AI, therefore, lies not in its inherent 'knowledge' but in its ability to facilitate insightful questions and collaborative exploration, ultimately augmenting human creativity and problem-solving.

Klarna Halts Hiring, CEO Claims AI Can Do All Jobs

Klarna CEO Sebastian Siemiatkowski has claimed that AI can already perform all jobs currently done by humans, leading the fintech company to halt hiring a year ago. The company's workforce has shrunk from 4,500 to 3,500 employees through attrition. While Klarna's website still advertises open positions, a spokesperson clarified that the company is not actively recruiting to expand but filling essential roles, mainly in engineering. This announcement has fueled concerns about AI's impact on the job market.

Nostr Protocol Basics: Events, Signatures, and Communication

Nostr Protocol Basics: Events, Signatures, and Communication

Nostr's NIP-01 outlines its core mechanics. Each user has a keypair, using Schnorr signatures on the secp256k1 curve. The core is the event, containing fields like ID, pubkey, timestamp, kind, tags, content, and signature. The event ID is the SHA256 hash of the serialized event data. Tags reference other events or users, with three standard tags defined: e (references an event), p (references a user), and a (references an addressable event). Event kinds define their meaning; NIP-01 defines two basic kinds: user metadata and text notes, and specifies how different kind ranges are handled (regular, replaceable, ephemeral, and addressable). Clients communicate with relays via websockets, sending events, requesting events, and closing subscriptions. Relays return events matching filters and send OK, EOSE, CLOSED, and NOTICE messages.

AI-Powered Dev: My Codescribble Debugging Nightmare

The author used LLMs to build Codescribble, a simple shared text editor. While the initial development was incredibly fast, almost entirely LLM-driven, deployment became a major headache. The generated code suffered from hardcoded values, inconsistent methods, and a broken automated deployment script. Ultimately, the author spent far more time debugging and fixing LLM-introduced errors than anticipated. This experience highlights the need for developers to maintain a solid grasp of underlying technologies and thoroughly review AI-generated code. Blindly trusting AI can lead to significant inefficiencies and even counter-productive outcomes.

Debunking the Myth: Thomas Watson and the Five Computers

2025-01-24

The widely circulated quote attributed to IBM's Thomas Watson, "I think there is a world market for maybe five computers," is revealed to be an urban legend. This article traces the quote's origins, demonstrating it's not from 1943, but a misinterpretation of his remarks at a 1953 shareholder meeting. Watson discussed sales projections for the IBM 701, not the entire computer market. This highlights the importance of verifying online information and the spread of misinformation.

Tramway SDK: A Lightweight Game Engine Defying Turbobloat

2025-01-07

Tramway SDK is a lightweight game engine challenging the 'Turbobloat' of mainstream engines like Unity and Godot. Developed over three years, it aims to bring 3D game development to older hardware. Using software rasterization, it eschews the need for a graphics card and runs on 15-year-old hardware, lowering the barrier to entry and reducing e-waste. It ditches node-based systems in favor of entity class inheritance and streamlined coding. Optional editors and whitespace-separated value configuration files simplify the workflow. Tramway SDK also includes an RPG framework, supporting level streaming and Quake/Source style entity interaction for easy open-world RPG creation. While still early in development, its lightweight nature and ease of use hold immense potential.

NASA Solves Ingenuity Mars Helicopter Crash Mystery

After nearly a year of investigation, NASA has finally solved the mystery behind the crash of Ingenuity, the Mars helicopter carried by the Perseverance rover. The helicopter's navigation system, unable to discern sufficient features on the relatively smooth Martian surface, resulted in a horizontal velocity upon landing. This caused Ingenuity to tumble, breaking its blades. Despite lacking a black box, investigators pieced together the cause from limited data and imagery. Remarkably, Ingenuity still communicates intermittently with Perseverance. The incident has prompted NASA to begin planning for follow-on missions, including a larger Mars helicopter capable of carrying scientific instruments.
