Security-Reviewing Uses of postMessage()

The postMessage() API is an HTML5 extension that permits string message-passing between frames that don't share the same origin. It is available in all modern browsers. It is not supported in IE6 and IE7.

B2G Quickstart for Payments and Identity

Before you begin: You want to do this on a Mac. I have been using Linux for months, and unresolved redraw issues (white screen of death) are killing me. Mac works great. Use OSX.

This sets you up to make two separate targets:

• One for a desktop [simulator] [1]
• One for the Unagi [device] [2]

These are the moving parts:

• [mozilla-inbound repo] [3] clone (hg)

Controlling addressable LEDs with STM32 SPI + DMA

Overview

RGB5050 LEDs are programmed by sending a stream of 24-bit GRB packets, MSB first.

The logical 1s and 0s in the packets are encoded on a single line which is sent high or low with these timings:

• 0 -> 0.3µs high ± 0.15µs, 0.9us low ± 0.15µs

#Tracking Down Memory Leaks in Node.JS

Last month, the Identity team at Mozilla delivered the first beta release of Persona. Getting to this point, we built a lot of tools to help us achieve the scalability and performance that Persona demands, and to help us with problems ranging from debugging to localization to dependency management and more. As a team, we hope our solutions will be useful to other developers, and of course we hope that other developers will help us make our tools even better. So we're kicking off a series of blog posts in which we're going to talk about

Fixing Ludicrous Java Localhost DNS Lookup on Mac

I recently started using the excellent adm wrapper for the android debug bridge.

I quickly noticed that my app was hanging on startup on an aarch_64 (Apple M1) machine.

Fortunately, vert.x, a dependency of adm, gave the following warning:

[vertx-blocked-thread-checker] WARN io.vertx.core.impl.BlockedThreadChecker - Thread Thread[vert.x-eventloop-thread-0,5,main] has been blocked for 4985 ms, time limit is 2000 ms
