The Internet is Cool. Thank you, TCP
IMAP

November 17, 2025 07:09 AM

TCP is a protocol that underpins much of the Internet. It controls reliable data transmission despite underlying network instability. TCP has mechanisms for flow and congestion control, which prevent overwhelming receivers and the network itself, along with allowing it to recover from packet loss, corruption, and reordering. This article provides C code examples with a simple TCP server and a basic HTTP server, showing how applications use TCP for reliable communication.

What if you don't need MCP at all?
IMAP

November 17, 2025 07:09 AM

MCP servers for browser automation with agents are often inefficient and hard to extend. Instead, simple Bash scripts and code for tasks like starting a browser, navigating URLs, executing JavaScript, and taking screenshots are usually more token efficient and more customizable. By cloning tool repositories and setting up an alias, these scripts become globally available to agents like Claude, making browser interaction easier.

The Inner Workings of JavaScript Source Maps
IMAP

November 17, 2025 07:09 AM

JavaScript source maps translate minified production code locations back to original source files, letting developers debug with proper variable names and formatting. This happens through VLQ (Variable Length Quantity) encoding with Base64 characters in the `mappings` field, which compresses position data by storing small relative differences between locations rather than absolute coordinates, separated by commas (for columns) and semicolons (for line breaks). Each mapping segment contains 1, 4, or 5 values that specify the generated file column, source file index, source line/column, and optionally the original identifier name, allowing tools to efficiently bridge production code and developer-friendly sources.

Anthropic's paper smells like bullshit
IMAP

November 17, 2025 07:09 AM

Anthropic's recent report on a Chinese cyber espionage operation coordinated by Claude may have been falsified. There is a lack of verifiable information and technical details. The report claims that the AI autonomously executed a significant portion of the attack, but it fails to provide IoCs, TTPs, or evidence to support its claims.

AGI fantasy is a blocker to actual engineering
IMAP

November 17, 2025 07:09 AM

The pursuit of Artificial General Intelligence (AGI) is bad for actual engineering. The belief in AGI, particularly within companies like OpenAI, is being used to justify environmentally damaging and exploitative practices in the pursuit of limitless scaling. AGI's supposed high expected value relies on arbitrary and unfalsifiable estimations while ignoring tangible negative externalities.

Supercookie is a method that uses favicons to create a persistent, unique identifier for website visitors, even in incognito mode and after clearing browsing data. It exploits how browsers cache favicons, allowing servers to track whether a browser has loaded specific favicons, creating a unique fingerprint. This tracking method affects major browsers and is difficult for users to clear.

Coinbase Data Breach Timeline Doesn't Add Up: I Have Recordings & Emails Proving Attacks Started Months Before Their 'Discovery'
IMAP

November 17, 2025 07:09 AM

This article goes over the personal experience of a sophisticated phishing attack targeting a Coinbase user in January. The author reported the attack, which involved the scammer possessing detailed personal information, to Coinbase, but received no response to their crucial question of how the attacker obtained the data. Coinbase later disclosed a data breach in May, attributing it to bribed overseas customer support contractors, but the author's earlier experience suggests the breach was active months prior.
