Technical Utility Bookmarks
These are some utility pages I keep bookmarked as technical references when developing. I’m going to treat this like an Awesome List, so it will be a work in progress as I add more bookmarks.
Crontab Guru
The crontab guru takes the guesswork out of crontab schedules: crontab guru. Paste in an existing schedule you are debugging or check out the example page for suggestions that might be useful for a new schedule.
Regex 101
A great sandbox for evaluating regular expressions: regex101. I reach for this tool whenever I need to develop a new regular expression.
SQL Online IDE
The SQL online IDE is a simple interface over a couple of common dialects: SQL online IDE. You’re not going to use it to build a DB, but it can be useful when working HackerRank SQL problems or prototyping data models.
Mockaroo
A tool for making simple mock data sets. I haven’t tested out the login features, but the basic functionality is really useful.
Neetcode.io
Great resource for preparing for software developer interviews.
