<strong>The Internet is Cool. Thank you, TCP (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
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.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
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.

<strong>The Inner Workings of JavaScript Source Maps (8 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
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 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.

<strong>AGI fantasy is a blocker to actual engineering (4 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
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.

<strong>Coinbase Data Breach Timeline Doesn't Add Up: I Have Recordings & Emails Proving Attacks Started Months Before Their 'Discovery' (12 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
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.

<strong>Behind the complaints: Our investigation into the suspicious pressure on Archive.today (7 minute read)</strong>
</span>

<br>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
AdGuard DNS was contacted by the Web Abuse Association Defense (WAAD), which demanded that it block Archive.today for hosting illegal content, with implied threats of legal action under French law. AdGuard's investigation revealed WAAD to be a recently formed, opaque organization with suspicious activities, potentially impersonating individuals and making false reports. AdGuard has filed a complaint with the French police and is investigating the connection between WAAD and the real lawyer.
