# Keystrokes + database TODO 21/11/2021
- Auto-completion (Emiel):
- [ ] use previous words (create wordgrams) AND first letters already typed (use n-grams)
- [ ] create new database, store on client side
- [ ] When do we update this database
- [ ] Do we also store this database on the server?
- Distance functions (Kobe + Rob)
- [ ] Validate how well this function works
- [ ] test functions
- [ ] Write documentation
- [ ] After concluding a different user is typing, check if this user is in the database or give the person in database with the highest probability
- Database (Kobe)
- [ ] optimize functions
- [ ] Think about how we are going to split the databases (To much work to read every time from a huge database)
- [ ] make a starting database with a few users
- [ ] Write documentation
- [ ] Change console.log(ERROR) to DEBUG module
- [ ] In personal database:
- ngrams of this person
- word-grams of this person (for word suggestions)
- [ ] Save in which rooms you want to share your timings + function to get if you gave permission in that chatroom
- [ ] Save messages locally and make a function to get these messages like `requestHistory()` in `ws-client.ts`
- Data collection (Rob)
- [ ] Change data-collection to work with blessed
- [ ] Extra check for special characters based on delta time

# Questions
- Keystroke analyse langs welke kant gebeuren (verzender of ontvanger)?
- Toestemming aan iedereen, aan een aantal personen of aan chatserver
- Testen op de server of op de client? Indien op client, op de ontvangende of versturende kant?
