  • Ask HN: How do you get an open-source product noticed by developers?
    In my experience, the developer tools that really catch on do so via word of mouth. For example, our whole team recently adopted https://sourcery.ai/ (not an ad) because one developer tried it and hyped it up to everyone else who also liked it. - Source: Hacker News / over 3 years ago
  • Google Python Style Guide
    To those that wish to automate a subset of these conventions, there is a tool called Sourcery[1] that I, personally, am a huge fan of! Not only does it have a large set of default rules[2], but it can also allow you to write your own rules that may be specific to your team or organization, and as mentioned it can enable you to follow Google's Python style guide as well[3]. There are some refactorings that Sourcery... - Source: Hacker News / over 3 years ago

  • Any simple/conservative lists that just block ads, not trackers that might break mobile apps and web sites?
    Split.io, segment.io, app-measurement.com, ... These domains do not really serve ads, they are used for analytics which one can argue is a privacy issue. But some Android apps just refuse to start if you block some of these domains. Source: almost 4 years ago
  • Dev is painfully slow
    People here must not be using Animation libraries, or A/B testing libraries (ala split.io) etc.. These bring in hundreds of modules alone.... terrible, but I'm thinking many of those posting aren't really building for serious enterprise production type websites. Source: about 4 years ago
  • What words do you like to put on your buttons?
    I looked up split.io and their website is worse. I see some technical jargon that I recognize, but the rest is gibberish. Makes me think there is room for providing better content in the space. Source: about 4 years ago
