  • Kindle to end store downloads and registering for 1st-5th gen kindles in May
    Calibre lets you put non-Amazon eBooks on these very same devices. It made me start using my old Kindle again: https://calibre-ebook.com/. - Source: Hacker News / 3 months ago
  • Your Old Kindle Isn't E-Waste: 3 DIY Projects to Give It a New Life [2026 Guide]
    Calibre is the open-source ebook management tool that's been around since 2006 and remains the gold standard. It converts between virtually every ebook format, manages metadata, and can push books to your Kindle over USB or wirelessly. - Source: dev.to / 3 months ago
  • anaconda on Xubuntu 24.04
    If I make the environment variable persistent in my .profile, Calibre's ebook reader does not work. - Source: dev.to / about 1 year ago
  • All Kindles can now be jailbroken
    I suspect most people that go this route (ie download and manage their own ebooks, then transfer them to their Kindle) use Calibre, which afaik, is unaffected by this change. https://calibre-ebook.com/. - Source: Hacker News / over 1 year ago
  • From RSS to My Kindle
    Very neat. I've been doing this with Calibre (https://calibre-ebook.com/), which involves plugging it into your PC via USB. Simple RSS feeds work with little configuration, and more complicated news sites require writing a custom python "recipe". This project uses Amazon's email gateway, which I think is limited to 25 articles per month (don't quote me on this). - Source: Hacker News / about 2 years ago

  • Is there and easy way of porting a site from d7 to d9?
    I would be interested in some good migration tools, paid ones are also ok. I found a post about this on drupal.org, but it didn't seem like an easy process. It is a multilanguage site with many content types, and a totally custom theme. Source: over 3 years ago
  • Is there any nice group, where I can ask questions, when I get stuck and recieve some guidance instead of crytics?
    You got already good advice, but wanted to point the guide of drupal.org where you can see some tools listed with instructions and channels https://www.drupal.org/community/contributor-guide/reference-information/talk/tools. Source: over 3 years ago
  • MAMP issue after Pro trial ended
    There is a service call GitPod that provides a temporary container Drupal environment. If you are familiar with what is going on around the future of how Drupal modules will eventually be offered up, you will likely have seen the "Project Browser" module as a contrib demo of the approach. It is used for people to give feedback to the developers. So they set up the typical 'SimplyTestMe' but also a GitPod... Source: almost 4 years ago
  • Best Modules for Product and Recipe?
    For reviews, it depends entirely on what you mean by "review". I believe core has a simple comment module, although it may have been deprecated for D9? There are likely many review-style modules on drupal.org that might work, or if you just want to link out to third-party reviews then it could just be a repeating-value link field on the Product content type. Source: almost 4 years ago
  • Leadership?
    They should also use standards tools like Github. The drupal.org platform was certainly impressive 10 years ago, today it's a pain to use it. They ducktape it with gitlab, but really it sucks to have to read documentation to simply do a pull request. Source: almost 4 years ago
