• make beautifull Collections GUI

Разобраться с сериализацией:

• имплементировать в нужных классах
• реализовать сериализацию в .csv
• разобраться со всем, что связано с сереализацией

Clear command clears data in database, but do nothing with
in-memory collection

1. Added element in client manager
2. show -> bug with show, but doesn't matter
3. shows in server, that id is very very big(should be psql db generated)
4. remove_by_id {that_long_id} doesn't do anything
5. entered db manually and saw, that id is 75, but remove_by_id 75 doesn't do anything either.

(check tg)

Make working logic for authentication:

• make sign in work
• make sign up work
• make icon clickable (choose between 4 languages by click)

also, check the see() method and all the logic here

For now, without multithreading

• should work perfectly in any situation
• all commands should work properly with database authorization
• check all the exceptions and functionality in bad situations
• make sure to add streamAPI whenever it is possible

• When opening and closing server city objects buplicate itself

• InputStreamReade
• BufferedWriter

Реализовать менеджера коллекций:

• написать список задач, которые он должен выполнять
• реализовать эти задачи

• Make translation of all readme's and naming's in repository to english
• make it using EN and RU tags in the main repository

i think this is really usefull for HR's, by the way

Необходимо реализовать многопоточную обработку запросов:

• Для многопоточного чтения запросов использовать создание нового потока java.lang.Thread.
• Для многопоточной обработки полученного запроса использовать Fixed thread pool.
• Для многопоточной отправки ответа использовать Cached thread pool.
• Для синхронизации доступа к коллекции использовать синхронизацию чтения и записи с помощью java.util.concurrent.locks.ReentrantLock.

• Fun task, if i have nothing to do - add javadocs to ALL laboratory works)
• This will improve readability, because... because why not)

My logic works like this:

• When saving executed, program executes INSERT statement, but in psql it just ADDS new objects to database. And i just collect EVERYRTHING. That's really really bad

Just occured in my head after passing 5th lab

what is the difference of InputStream and Reader on low level?

i mean, symbols are also bytes, so what is the difference?

• Make beautiful authentication GUI as in prototype

This is a really tough task

it involves:

• properly working with locality
• loading collection to TableView
• working with add, edit, delete and other commands
• implementing lab7 architecture and modifying it to work with gui
• filtering collection using StreamAPI
• add "geo" icon, same as in login, so that you could change locally in the Colections window

i will make comments as i progress, wish me luck with this one

• comparator
• comparable
• anonymous class
• static nested class
• non-static inner class
• lambda expression

Design PostgreSQL database:

• create datalogical diagram
• write model initialization script
• write PostgreSQLManager for lab7 to work with it

After adding object manually and executing show command - it is not showing up in the in-memory collection

• check CityHandler and show command and debug them
• make synchronization for show command
• make sure that this method works alright with multithreading

Bug when executing show command:

• should add tutorials to the main readme for each lab

Either pushing or userManager not working correctly. That's why is is just not filling with anything.
Need to figure that out.

Add this things:

• books
• lectures
• tutorials/guides

P.S.
1. try to get rid of unnecessary files to not to confuse others
2. add links and releases for projects
3. add good README's with links to UML's, reports and all the usefull stuff
4. those things should be placed in table's for better readability

вроде пакеты с маленькой буквы принято называть

Try to host javadocs for lab5-lab8 in the same github-io website via /docs directory in main
i think it is possible and if it really is - that would be rly cool)

I had an idea, that exception could be something like "there is no sound in space" in case if there is no oxygen.

in Moon.java, ofc.
