    While many images are of high quality, some older images or those from certain missions may not meet the same standard, which can affect consistency in visual presentations.
  • User Interface Limitations
    The website's interface, though functional, might not be as intuitive or modern compared to other digital libraries. This can sometimes make navigation less user-friendly, especially for first-time users.
  • Limited Metadata
    Some images and videos come with limited metadata, which can pose challenges for users seeking detailed information on specific media or requiring comprehensive data for research purposes.
  • Content Overload
    The sheer volume of available content can be overwhelming and might require users to invest significant time in filtering and identifying the most relevant images or videos for their needs.

    For extremely large inputs or very complex regular expressions, the tool may experience performance lags or slowdowns.
  • 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.
  • Privacy Concerns
    Users inputting sensitive data need to be cautious, as the web-based nature of the tool could raise privacy or data security concerns.

  • Just discovered huge collection of vintage NASA space mission photos
    If they're all Apollo mission images like the one above, those have all been scanned from the original flight film (mostly by me) and archived. We have digitally archived ALL of the manned mission flight film. We're currently working on digitizing what we call "institutional" imagery, images shot by Earth bound NASA photographers. We're only up to 1968 so far so we have a long ways to go, but we'll scan them all... Source: about 2 years ago

    Note: We pull these from https://images.nasa.gov, and are not endorsed by NASA in any way. We simply like space pics. Source: about 2 years ago
  • Shuttle TSM vs. SLS TSMU Retraction
    I think you'll be able to find some other footage on the NASA media library. Outside of that, you'll have to FOIA. Source: about 2 years ago

  • Learning Perl - Regular Expressions
    Use Online Tools: There are many online regex testers and visualizers that can help you see how your patterns match against sample text. These tools often provide explanations for each part of the regex. I personally use https://regexr.com/. - Source: dev.to / 8 days ago
  • The importance of the environment in Regex pattern matching
    However - here it becomes weird - when testing the original regex rule (the first one, without the \u00A0 part) on the same string in an interactive visualiser (https://regexr.com/ for instance), there is a match:. - Source: dev.to / 8 months ago
  • 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 still includes a shell component for accessing it's documentation, that was invaluable in those ancient times. Perl's regex documentation is rather fantastic. `perldoc perlre` from your terminal. Or... - Source: Hacker News / 10 months ago
  • Ask HN: How did you learn Regex?
    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
