Anki users are protective of their streak - the number of consecutive days they’ve done their reviews. Right now, for example, my streak is 621 days. So if you miss a day for whatever reason, not only do you have to deal with double the number of reviews, but you also deal with the emotional toll of having lost your streak.
You can lose your streak for one of several reasons.
When the Anki application is open on the desktop, it places a lock on the sqlite3 database such that it can’t be queried by another process. One workaround is to try to open the database and if it fails, then make a temporary copy and query that. Of course, this only works with read-only queries. Here’s the basic strategy:
#!/usr/local/bin/python3 # -- coding: utf-8 -- # requires python >= 3.8 to run because of anki module from anki import Collection, errors if name == "main": try: col = Collection(path_to_anki_db) except (errors.
It’s always best to let Anki set intervals according to its view of your performance on testing. That said, there are times when directly altering the interval makes sense. For example, to build out a complete representation of the entire Russian National Corpus, I’m forced to enter vocabulary terms that should be obvious to even elementary Russian learners but which aren’t yet in my nearly 24,000 card database. Therefore, I’m entering these cards gradually.
Recently I hit an extra digit when setting up a custom new card session and was stuck with hundreds of new cards to review. Desparate to fix this, I started poking around the Anki collection SQLite database, I found the collection data responsible for the extra cards. In the col table, find the newToday key and you’ll find the extra card count expressed as a negative integer. Just change that to zero and you’ll be good.
