The Node.js TSC participated in an AMA recently. I was lucky enough to be one of the TSC panelists. You can read about the AMA on the OpenJS Foundation blog, or watch the full video here.
This post is a more detailed followup to this tweet in which I advocate for using Node's assert module as your goto assertion library.
A key aspect of understanding a program's runtime behavior is identifying where it is spending its time. Generally, an application will either be waiting on I/O or performing calculations using the CPU. Node.js is excellent at handling large amounts of I/O, but must be cautious about CPU utilization because of its single threaded nature. Luckily, developers can identify, and even visualize CPU hotspots in their code using a profiler.
Node.js seems to increase in both popularity and sophistication on a daily basis. The project recently scored a major feature, as support for the V8 Inspector was merged into Node's master branch. This gives Node applications direct integration with DevTools, the top notch debugging tools that ship with Google Chrome. Unlike previous tools like Node Inspector, there are no required external dependencies except Chrome. The Chrome Debugging Protocol, used by V8 Inspector, can also communicate with tools from other vendors such as Microsoft and Firefox.
The Internet is not a safe place. Sometimes, not even the simple act of downloading a file is what it seems. On February 20th 2016, hackers created a modified Linux Mint ISO containing a backdoor, and linked to it from linuxmint.com. A blog post was issued containing instructions for detecting the compromised ISO.
In September of 2015, I gave a talk on Node v4.0.0 at the Nova Node meetup. The talk covered the road to v4, the io.js fork, convergence, what has changed, and a look into the future, including LTS. You can listen to the talk here.
NodeUp is a popular podcast covering the Node.js community. In July of 2015, I was a guest on episode #88, which focused on the ongoing Node.js/io.js convergence process. You can listen to the entire episode here.
