Possible disadvantages of CrackCode.dev

  • Limited public information
    There is little verifiable detail available about CrackCode.dev, making it difficult to assess its quality, reliability, and long-term maintenance.
  • Uncertain content depth
    Without confirmed information, it is unclear whether the platform offers a large, high-quality problem set comparable to established competitors like LeetCode or HackerRank.
  • Possible cost or paywall
    Many interview-prep platforms lock premium content behind subscriptions, so key features may require payment, which could be a barrier for some users.
  • Brand recognition
    Being a lesser-known platform, it may lack the credibility and employer familiarity that larger, established coding sites carry.
  • Language and feature limitations
    Smaller platforms sometimes support fewer programming languages or have less polished tooling, editors, and feedback compared to major established alternatives.

  • My thousand dollar iPhone can't do math
    Qalculate is my favourite REPL-like calculator, although it unfortunately lacks an iOS app. It feels similar to using an HP 48-series calculator. Numbat is similar, but more CLI/REPL-focused, and with more of an emphasis on being a programming language. - Source: Hacker News / 7 months ago
  • Show HN: Unsure Calculator โ€“ back-of-a-napkin probabilistic calculator
    Https://qalculate.github.io can do this also for as long as I've used it (only a couple years to be fair). I've got it on my phone, my laptop, even my server with the qalc command. Super convenient, supports everything from unit conversion to uncertainty tracking The histogram is neat, I don't think qalc has that. On the other hand, it took 8 seconds to calculate the default (exceedingly trivial) example. Is that... - Source: Hacker News / over 1 year ago
  • Frink
    Interesting project. I use command line Qalculate [1] for this (has a very similar feature set to Frink AFAICT) and Pint [2] for scripting. I feel like unit-aware calculators are hugely underused by physical engineers, it's the same idea and benefit as type safety but they're virtually unheard of, everyone just uses excel. Having guaranteed dimensional correctness is so great for the early design stage, it makes... - Source: Hacker News / over 1 year ago

    1) a scientific calculator with history and variables with a UI similar to https://sourceforge.net/projects/alt1-calculator/ that also can do units like https://qalculate.github.io/ 2) a tiny text chat direct message program that is similarly as easily accessible at Atl1 3) a minimalist dock of as many instances you would like similar to https://punklabs.com/rocketdock, and like where WIN opens the start menu, WIN...
