Here are a list of sites that help when it comes to looking up, learning, or researching the English language.
The following are some tools I'd like to note down that are handy when it comes to checking server configurations and security:
I came across Forvo today. It's a community-driven database of word pronunciations which appears to include multiple languages and accents and also accommodates proper nouns such as names etc.
I came across a neat service named Cryocopy earlier today. What it essentially does is mimic the service provided by archive.org except for the fact that Cryocopy does it on demand instantaneously and saves a screenshot to boot.
CryoCopy is a web archiving service that allows manual caching of Internet pages, fully saving them both in HTML and in bitmap (PNG) format. This is done almost instantly upon request, not days or weeks apart, like with other services.
