  • Limited Advanced Features
    RegExr may lack some advanced features found in more specialized or professional regex tools, such as integration with development environments or extensive scripting capabilities.

    Notion has helped in documenting our business

    It's been very very helpful to streamline different people on our team, especially remote workers to help them understand what's going on in our business without 100s of meetings.

    👍 Pros:    Ui is very attractive|Easy to use|Great for collaboration|Good customer service|Free to use
    👎 Cons:    Steep learning curve

    Extremely helpful- made life easier

    My remote-first start-up has eliminated more than 200+ hours of meetings and 1000s of mismanaged documents because our entire communication happens through Notion.

    👍 Pros:    Clean ui|File sharing|Modular
    👎 Cons:    Learning curve

    As someone who's always on the lookout for the perfect productivity app, I was excited to try out Notion. It promises to be an all-in-one tool for everything from note-taking to project management to personal wikis.

    From the moment you open Notion, you can tell that it's different from other productivity apps. The interface is sleek and modern, and it's easy to navigate. The app is divided into pages, which can be customized with different templates to fit your needs. You can create to-do lists, databases, wikis, calendars, and more.

    One of the things I love about Notion is the ability to create relationships between pages. For example, you can create a database of your favorite books and then link to a page with your book reviews. Or you can create a to-do list and link to a page with notes about the task. This feature makes it easy to keep all of your information in one place and to connect related items.

    🏁 Competitors: Microsoft Loop
    👍 Pros:    Highly customizable|All in one|Collaboration|Cross platform
    👎 Cons:    Steep learning curve

  • Ask HN: How did you learn Regex?
    Learned regex in the 90's from the Perl documentation, or possibly one of the oreilly perl references. That was a time where printed language references were more convenient than searching the internet.

Perl's regex documentation is rather fantastic. `perldoc perlre` from your terminal. Or... - Source: Hacker News / 10 months ago

    I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches. One of the things I remember being difficult at the beginning was the subtle differences between implementations, like `^` meaning "beginning of line" in Ruby (and others) but meaning "beginning of... - Source: Hacker News / 10 months ago

    I manage my non-work and work-adjacent tasks in Notion.
