  • (2020-02-13) Diana: Código corto e interesante para aprender un poco más cada día. Me parece una iniciativa genial. Buen trabajo!!
  • (2020-02-08) Joe Lei: Many of the Javascript examples utilize array reduce which is generally frowned upon by developers. It's not recommended to use reduce because it's hard to read. I feel like the examples sacrifice elegance over code readability too much.
  • (2020-01-14) Dimon210: Good extension. But, please, add C#.
  • (2019-12-31) Maria Stervic: Total ripoff of 30 seconds of code.
  • (2019-12-25) Ten Tackle: The extension is terribly outdated and rips off a bunch of open source projects. Visit the official website - https://www.30secondsofcode.org/ - instead!

Latest issues

  • (2021-03-17, v:1.2.0) Maciej Sulecki: Unusable without these features:
    - Show once per a number of new tabs opened - Show only on the startup page not every new tab - Don't show during working hours - eg. 9am-5pm - Show bookmarks bar on this page (in chrome when you disable bookmark bar it shows only on the new tab page - it would be great if it could show on your page as it aims to replace the chrome's new tab) Without these features its too much noise, it's too annoying and badly influences productivity. Implement at least some of these and it will be usable - especially if you aim for developers, I love the product but can't use it in the current state.
  • (2020-10-08, v:1.2.0) Fathah Crg: I installed the extension, but how can I see the result
    I have already installed the extension, but how can I see the result. When I open a new tab nothing is showing up.
  • (2020-05-18, v:1.2.0) Benjamin Hurand: "30 seconds of knowledge" on Opera GX
    Hello, I discovered your addon during an internship I made and I loved the concept but I'm currently using Opera GX and I can't manage to make your addon work completely on my Web Browser. I have managed to get the addon installed using an other addon created by Opera itself wich allows to install Chrome Addons on Opera and it worked fine but I can't manage to get the Snippset on each New Tab : I can only get a random snippset manualy clicking on the extension in the right corner. If you could help me to fix this issues it would be so nice and I would be so gratefull. Or if you could adapt your addon and upload it on the Opera Store directly, it would even be so much better. Thanks you for your attention and your consideration. Benjamin Hurand
  • (2019-12-11, v:1.2.0) Ростік Попович: new language
    Please add java and kotlin Thanks
  • (2019-04-08, v:1.2.0) Phil Whelan: Why do you need access to browser copy and paste data?
    This poses a security issue.
