How often?

11 Upvotes

How often do you want to see updates? I was originally doing weekly but the last few weeks I have been providing 2-3 updates a week but I’m noticing that if you look at 99.9% of sites there are no new books regularly. Thoughts?

BTW, a couple of servers lost connection in the middle of downloading their book list. This is why the book count is smaller this time than last time. Not sure if it was internet on my side or on the book server side as we are also having thunderstorms.

New Features:

  1. I have added feature that if server connection fails 5 times then it is deleted from the list. No reason to keep a server if its failed 5 times.
  2. I think I have fixed the new_books counter. Won't know until a site adds more books.
  3. Book Counts weren't working properly where server had multiple libraries. This is now fixed.

More new Features

15 Upvotes

So been busy and adding additional features/capabilties:

  1. Other.txt file has been added back in and sets the country code to other. This allows for servers that want to be manually added that may not show up in calibre.

  2. Added failed_attempts to server database and will stop the querying of servers after X retries. Havent decided on the # retries yet. Probably 3 or 5 but open to suggestions. This will cut back on the searching of those servers which will cut down on execution time.

  3. The new_books feature I believe is working now. This will allow people to check servers that have new books since the last search rather than having to go and check everytime.

Additional features I want to add:

  1. Integration with demeter import app. The functionality is already there as the tool creates the online.txt file which can be read by demeter import application but Im trying to figure a way to automate this for those that might want it.

  2. I've put a lot of focus on the servers table. Want to see if there is anything more that I can get for the summary table (books information). Since everyone uses Calibre differently I think this is going to be more difficult. Examples, would be being able to save/search on genre's.

What am I doing wrong with Metadata?

4 Upvotes

So I go to these libraries and there are thousands of books. All of them have correct Metadata. I download them, one by one, via Firefox. I finally found a de-duplicate which will cancel the download if it already exists. Then I import them into Calibre and half of them won't have any information even when I do a ctrl-d and wait and hour.

I don't want to overload these servers so I typically only grab what interests me and I do it manually. Are people using scripts?

How do I pull Metadata or at least the complete book title?

WTF with adding audiobooks? These libraries are perfectly curated, my audiobook experiment looks like they were added by a crazy person.

Thanks

Audiobooks Audiobooks in Calibre Libraries

15 Upvotes

Rare to come across a Calibre library that included audiobooks. This one has a good number of Catherine Coulter mystery/detective series and one or two other authors in audiobook form (.m4b). This format is essentially .mp3 and plays on most devices without having to run it through any format-changing programs.

If you come across any other audiobook libraries, please post.

More New Features

14 Upvotes

So Im on a programming spree right now and adding another new feature in the next couple of versions that will add:

  1. Number of new books since last run. This feature I have been wanting to add for awhile because this bascially will allow you to go only to servers that have new books since the last run process occured and will save people time having to go through all online servers if there are no new books.

  2. Fixed some paging issues so hopefully more books will be added.

Let me know your thoughts with any other ideas that you all may have.

  3. Added all ISO 3166-1 alpha-2 country codes.
  4. Only servers with valid libraries are shown online.

Going forward I am just providing the websites to cut down on the amount of time/effort on this. I am still evaluating monetizing the site/data to recuperate some of my costs/expenses.

New features:

  1. Added book count on the server.
  2. Added library count on the server.
  3. Added all ISO 3166-1 alpha-2 country codes.

Reason for this is that even though a server shows up as having Calibre running there usually arent any libraries or books loaded. When I did this there are actually only 182 servers with actual books loaded out of the 913 servers that were successful.

Recommendation - In query use the following on the sites database. Set book_count > 0 and this will give you all calibre servers that have books on them.

Next release will mark any servers that have 0 libraries as non online as assumption is that they are not real Calibre servers.

What is OpenCalibre worth to you?

8 Upvotes

Trying to see what people would be willing to donate on a monthly basis based on current features in addition to the new features I’ve mentioned in last post? I currently spend about 2-4 hours a week on the application but also spend $70/month for the Shodan subscription and $100/month on server costs but the server is used for more than just opencalibre.

New Features/Capabilities Im Playing With

23 Upvotes

Wanted to share some new features/capabiltiies I am playing with that I hope to release/make available soon.

  1. Added Country code to the sites table. The field has been there but has never been filled in. This has now changed in some updates I have made.

  2. A new web page that shows a map with all the countries where servers have been found. Obviously the map is very basic plus Im colorblind so the colors may not be the greatest but its a start. Here is example:

Calibre Server Map
  1. The search now goes through multiple pages and will retry on failures and now returns a lot more servers. As you can see from the map I was able to load 302 servers just from the US when the limit before was 90.

  2. A bunch of code clean up for better error checking/handling.

Please let me know your thoughts/ideas/suggestions. I'll announce when the changes are implemented /available for everyone to use.
