  • Learning Curve
    While the tool is user-friendly, users still need to have a foundational understanding of regular expressions to use RegExr effectively.
  • Performance Issues
    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.

  • 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 / about 17 hours 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

    Mostly building things that needed complex RegEx, and debugging my regular expressions with https://regexr.com/. - Source: Hacker News / 10 months ago

  • NASA Stennis Releases First Open-Source Software
    Just to be clear this is one center’s first open source release. There’s open source from other centers at https://github.com/nasa. - Source: Hacker News / 27 days ago
  • FBI, Partners Dismantle Qakbot Infrastructure in Multinational Cyber Takedown
    NASA has a good set of open source projects available for public use: https://code.nasa.gov/. - Source: Hacker News / almost 2 years ago
  • NASA's Software Catalog offers hundreds of new software programs for free
    Yes, this is no-cost but not necessarily open source. NASA open source software can be found at: https://code.nasa.gov/. - Source: Hacker News / almost 2 years ago
  • Public satellite telemetry data?
    As for public telemetry it might be hard to get it for free as satellite owners do it for money. NASA maintains a public software page at code.nasa.gov and software.nasa.gov which includes OpenMCT mission control software that can do simulated data. Source: over 3 years ago
  • Internship/research as a physics major
    Don't underestimate the strength of personal projects. If you ask a professor about their research, I find very often, they ask about things you have done in the past, which sort of feels like shit if youve done nothing huh? I know people who made cloud chambers or shot ions or massive simulations in HS and I was like, a theatre kid which is so irrelevant. BUT. The reason they ask this is that previous experience...
