How to use `subprocess` command with pipes
...shell=True.
However, this isn't really advisable for various reasons, not least of which is security. Instead, create the ps and grep processes separately, and pipe the output from one into the other, like so:
ps = subprocess.Popen(('ps', '-A'), stdout=subprocess.PIPE)

This still requires a .csr file generated from xcode, at least, from what I've found. From developer.apple.com/account, I go to "Certificates, IDs & Profiles"->"Profiles". I see a ReleaseProfile and a TestingProfile. Both show "Invalid" under the "Expiration" column. I click...
Is it good style to explicitly return in Ruby?
...ws! Only a full code review of all calls will let you know.

How do you uninstall all dependencies listed in package.json (NPM)?
..., some dependencies get really deep. On the NTFS file system (Windows), at least, it has problems removing directories where the path name is longer than some kind of limit, leaving these phantom directories that you can't remove. Fortunately, npm uninstall takes care of that, which is why this tric...
