Quote of the Week

"The key is to acknowledge from the start that you have no idea how this will grow. When you accept that you don't know everything, you begin to design the system defensively... You should spend most of your time thinking about interfaces rather than implementations." - Nicholas Zakas

How to build large-scale end-to-end encrypted group video calls
Signal released end-to-end encrypted group calls a year ago, and since then we’ve scaled from support for 5 participants all the way to 40. There is no off-the-shelf software that would allow us to support calls of that size while ensuring that all communication is end-to-end encrypted, so we built our own open-source Signal Calling Service to do the job. This post will describe how it works in more detail.

Patterns for Authorization in Microservices
It's interesting, we talked to over 50 companies about their authorization systems and more than half of them are using microservices in some shape or form. We found that no one seems to agree on best practices for authorization in service-oriented backends and dug into this further.

A deep dive into an NSO zero-click iMessage exploit: Remote Code Execution
Earlier this year, Citizen Lab managed to capture an NSO iMessage-based zero-click exploit being used to target a Saudi activist. In this two-part blog post series, we will describe for the first time how an in-the-wild zero-click iMessage exploit works.

Better project environment management with direnv and asdf
Load per project environmental settings and runtimes while ridding yourself of multiple runtime managers (rvm, nvm, etc.)

Reverse Engineering the Firebase Realtime Database Wire Protocol
In this interactive notebook, we instrument the Realtime Database client and create a number of repeatable in-browser experiments to understand the wire protocol. We then confirm our understanding by bringing up our own Fake Realtime Database Server and connecting it to an unmodified SDK.

You Can't Buy Integration
You can’t buy integration, but that’s OK; it’s worth the investment to build it yourself. After all, it may be the most strategic software in your portfolio.

HTML Sanitizer API
A set of APIs which allow developers to take untrusted HTML input and sanitize it for safe insertion into a document’s DOM.

Back to basics: threads
Where does the JVM take threads from? How much does a thread cost? How do the threads interact and is my CPU any different from the distributed system?
