When Zork arrived, it didn’t just ask players to win; it asked them to imagine. There were no graphics, no joystick, and no soundtrack, only words on a screen and the player’s curiosity. Yet those words built worlds more vivid than most games of their time. What made that possible wasn’t just clever writing, it was clever engineering.

Beneath that world of words was something quietly revolutionary: the Z-Machine, a custom-built engine. Z-Machine is a specification of a virtual machine, and now there are many Z-Machine interpreters that we used today that are software implementations of that VM. …

During OpenAI’s GPT-5 launch event, they demoed the model’s ability to fix real bugs in production code. Live on stage. In their own repository. The kind of demo that makes CTOs reach for their credit cards and engineers nervously update their resumes. There’s just one small problem: the fix they promised to merge “right after the show” is still sitting there, unmerged, three and a half months later.

Wanna hear a joke about construction? I am still working on it🤣

Why did the developer go broke? Because he ran out of cache 🤣

A good overview of their tests and findings surrounding Flock cameras. Goes through some approaches on manipulating and monitoring the cameras themselves, but also the hosted Flock platform, police, shared data, and politics.

binfmt_misc (short for Binary Format Miscellaneous) is a Linux kernel feature that allows the system to recognize and execute files based on custom binary formats. It’s part of the Binary Format (binfmt) subsystem, which determines how the kernel runs an executable file.

In 2019, SentinelOne published a two-part analysis describing a persistence technique called Shadow SUID (Part 1, Part 2): Shadow SUID is the same as a regular suid file, only it doesn’t have the setuid bit, which makes it very hard to find or notice. The way shadow SUID works is by inheriting the setuid bit from an existing setuid binary using the binfmt_misc mechanism, which is part of the Linux kernel.

Interestingly, this technique seems to have fallen into oblivion again, as neither MITRE ATT&CK nor the five-part Elastic Security “Linux Persistence Detection Engineering” series mentioned it (the last part here with links to all other parts). As of 2025, however, the technique works wonderfully and would probably be very difficult to detect (see the hunting section later).

Central to Copilot Studio’s innovation is its deep integration with .NET, including the use of .NET on WebAssembly (WASM).

This post explores how Copilot Studio utilizes .NET, the benefits realized from platform upgrades, and the resulting performance, cost, and productivity improvements.

Copilot Studio is a low-code experience for creating conversational and autonomous agents, but the runtime executing those agents is based on .NET.
