Stop Repeating Yourself in Code Review: Build a Custom Mago Lint Rule

Stop Repeating Yourself in Code Review: Build a Custom Mago Lint Rule

Video version: https://youtu.be/Sns4iMSa3qA Every team I have ever worked on has a rule that lives in someone’s head instead of in a tool. An example of this is that if you’re working with a Laravel project, you should use Illuminate\Support\Carbon and not Carbon\Carbon directly. We all knew it, but we still shipped the wrong import […] The post Stop Repeating Yourself in Code Review: Build a Custom Mago Lint Rule appeared first on PHP Architect.

Just a rumour of a bug is enough to find a security exploit these days

Just a rumour of a bug is enough to find a security exploit these days

Just a rumour of a bug is enough to find a security exploit these days Anil Madhavapeddy is a professor of computer science at Cambridge and a core maintainer of the OCaml compiler. In this somewhat alarming post he reports that security issues in OCaml projects are seeing evidence of attempted exploits within minutes of patches being shared for discussion: This normally takes a few days and a release within a week or two is reasonable. Within about ten minutes (!) this website was fielding…

Socket Now Protects the Microsoft Edge Extension Ecosystem

Socket Now Protects the Microsoft Edge Extension Ecosystem

Today, Socket is expanding browser extension security to Microsoft Edge. Enterprise security teams can now evaluate extensions published through Microsoft Edge Add-ons and monitor new releases for malicious behavior, excessive permissions, data collection, suspicious infrastructure, and changes that introduce new risk. This brings the same code and behavioral analysis already available for Chrome and Firefox to Microsoft’s extension ecosystem. Socket examines what an extension can access, what…

Tokens Aren’t Dollars

Tokens Aren’t Dollars

The following article originally appeared on Tim O’Brien’s Medium blog and is being republished here with the author’s permission.

Writing really is an Emotional Rollercoaster

Writing really is an Emotional Rollercoaster

[[Writing]] has become my passion over time; I have built a whole company based on technical writing services (even though most say that’s impossible). After doing it for 11 years publicly (much longer privately), I still enjoy it every day. If I could have one dream, I’d probably imagine the book-author lifestyle, where I go to a faraway place or island and just write in my journal, articles from my vast notes system (~3 million words, or 2-3 books.

Breaking Claude Code Opus 5 Auto Mode

Breaking Claude Code Opus 5 Auto Mode

Breaking Claude Code Opus 5 Auto Mode Anthropic are putting a great deal of faith in Claude Code's auto mode for protecting their coding agent users against prompt injection attacks. They recently made that the default and have made bold claims about its effectiveness. Johann Rehberger is one of the most credible prompt injection researchers active today. He found an attack against auto mode which he claims works 80% of the time, by tricking Claude Code into downloading and uncompressing a zip…
