Greg Navis discusses why he thinks single-page applications (SPAs) are almost always worse than traditional, multi-page web application. I tend to agree: Most of the time, it adds engineering complexity for not much benefit. I think this is particularly the case when using Elixir and Phoenix, since their performance is spectacular. Phoenix Channels already provide a way for updating content on a page without reloading, and the upcoming Live View promises to make it even better.
This post by Luca Guidi explains with great detail how calculating elapsed time in Ruby can have it’s pitfalls. The TLDR:
## Don't do this: starting = Time.now # time consuming operation ending = Time.now elapsed = ending - starting elapsed # => 10.822178 ## Do this: starting = Process.clock_gettime(Process::CLOCK_MONOTONIC) # time consuming operation ending = Process.clock_gettime(Process::CLOCK_MONOTONIC) elapsed = ending - starting elapsed # => 9.183449000120163
In this post, the [[Atom]] team explains how you can create composed commands from existing commands already available in your editor. This feature seems great for automating tasks. I haven’t composed any commands of my own just yet, but I think this is a great addition.
