Curios about the impact of this on the Go compiler and the security implications? Read my blogpost :) dreadl0ck.net/posts/faster-b…

Faster builds on macOS: a good idea? - Philipp Mieden

Explore how to speed up Go and Rust compilation on macOS by bypassing XProtect checks. Includes benchmarks, security implications, and performance analysis of Developer Tools exemption.

TIL that macOS has a security feature called XProtect, which scans any new binaries you execute But it also means it slows down edit-compile-run workflows with excessive checking And the daemon is single threaded, so concurrent binary executions are blocked good lord

I'm glad everyone has discovered memory safe languages after several decades. Now can we start looking at secure package management or are we just going to import memory safe rando libs from ninja876 on Github forever?

My dystopian vision of an AI-powered future is that LLMs drives down the cost of generating long text even further, and the only way for readers to keep up is to use LLMs to summarize.

Okay here's a ridiculous (but true) take: word processing is bad. Before it, document length was bounded by the human capacity to copy long-form text. After word processing, the tax & legal codes grew without check. And became incomprehensible to anyone but career experts.

Awesome 👏 go.dev/blog/vuln
You can force any v8/Electron process to execute arbitrary js code (child_process, http, etc) by forcefully enabling and abusing the builtin debug mechanism ... here's VS Code executing Calc, but I suspect any Electron app is susceptible 🔥 it works with SIP enabled on macOS

Pretty cool that @github warns about the use of bidirectional unicode text in source code! Nice feature

However, the homoglyph function example is not detected
The Trojan Source vulnerability allows supply-chain attacks on software written in C, C++, Go, Java, Javascript, Python and Rust. We're releasing details after a 99-day coordinated disclosure period, and some of these compilers will be patched quickly. See lightbluetouchpaper.org/2021…

Wow, just realized C is turning 50 next year. Not sure how to tell students that we're learning about security problems caused by a language that's half a century old.
