To submit your homework you need to do following:
- Everyone need to fork this repo with his personal github account.
- Everyone should create separate folder with his name and surname and upload it to this repo ( for example Valentine Zavadskiy ).
- Every task should be executed on separate branch and you need to create a folder inside your pesonal folder, representing number of homework ( for example for homework #0 - Valentine Zavadskiy/0/ )
- After you finished your homework - you need to send a pull request ( PR here and futher ) to master-branch of this repository. Name format of this PR should be #{first_name} #{last_name} - #{homework number} ( for example Valentine Zavadskiy - 0 ). Please make sure you filled all fields on template.
- After submitting PR it will be automatically checked against code styles. Please make sure you fixed all warnings. We are not accepting homeworks with style violations.
- After all warnings are fixed - we will assign mentor to your homework, so he can manually look throught your code and leave his comments.
- After you discussed your work with mentor and he decided that it is OK - your pull request will be merged to main repository. Only at this moment your work will be considered as accepted.
If you looking into Belarussian IT industry - you might hear about Viktor Prokopenya, who is a famous enterpreneur here. Recently he gave interview on youtube. During this interview one of keypoints which was discovered - he does not know how much bread costs these days. Our goal for todays homework will be help such people to learn about pricing for different basic items.
- Data for this homework should be downloaded from this webpage
- You should NOT include this date to your pull request, just place everything to
datafolder and ignore it.
On this level you should create a basic program, where you can enter a name ( in Russian ) and it will give you an answer if item is found.
Examples:
ruby run.rb
What price are you looking for?
> Хлеб
'Хлеб' is 1.14 BYN in Minsk these days.
> Профитроли
'Профитроли' can not be found in database.
On this level you should add more power to your program and make it look for minimal and maximum pricing over the time.
Examples
ruby run.rb
What price are you looking for?
> Хлеб
'Хлеб' is 1.14 BYN in Minsk these days
Lowest was on 2017/01 at price 0.72 1.73BYN
Maximum was on 2012/04 at 1.73BYN
With this level you also should tell user what else he can get for similar price.
Examples
ruby run.rb
What price are you looking for?
> Хлеб
'Хлеб' is 1.14 BYN in Minsk these days.
Lowest was on 2017/01 at price 0.72 1.73BYN
Maximum was on 2012/04 at 1.73BYN
For similar price you also can afford 'Йогурт' and 'Кефир'.

If you are familiar with battle-rap, you probable heard about word plays. If you never heard about that, you can go and check this link to get some understanding. On this homeword we will try to write a telegram-bot, who could help different people generate some wordplays.
On this homework we will practise how to:
- Write data scrapers from website
- Create telegram bots
- Structure your code with multiple classes
- Use third party gems
- Store persisted data on database
- Data for wordplays should be parsed with custom script and saved to database. Those scripts should be included to your submission
- For database storage you should use
redisdatabase and use 'redis' gem for this. - For telegram bot you should use
telegram-bot-rubygem. - Your code should be well-scructured with multiple classes
- You can choose any language you love ( Russian, English, whatever ) to get a data for this.
- It's up to you how you will define wordplays or get data for them. In the very end it should be just funny. One of the best ways of detecting and generating them is to do some simple sound analysis about different words in a vocabulary. Or you can lookup some website with wordplays and parse it.
For this homeword we are going to have only one level will have only one command, which will simply take one wordplay or phrase from database and print it on your telegram.
Here is an example:
> Hey bot!
> Hey bro!
> /wordplay
> Here is your random wordplay:
> She got a big __booty__, so I call her big __booty__

So new homework is about keeping you in fit, so just track what you eat and you'll live forever. Or a fairy tale about one more foodtracker.
On this homework we will practise how to:
- Create simple rails application
- Use generators
- Use associations
- Use third party gems
- Store persisted data on database
- There are three entities: a user, a dish and an ingestion.
- Each entity has set of fields.
- User: first_name, last_name, age, weight and height
- Dish: name, weight, calorie_value, proteins, carbohydrates and fats
- Ingestion is who ate and what was eaten
- For database storage you should use
postgresqldatabase and use 'pg' gem for this. - Your code should be well-scructured with multiple classes
- Nobody should die of eyes bleeding. Use CSS power!
- Check previous lectures for help.
The easiest thing you can do is implement functionality for user who can perform following operations: sign up/log in/log out and profile editing. If you think that it's enough - you are wrong. You need to add all entities and needed operations for foodtracker.
It's not funny to look at number of rows in tables, so please show stats in charts
Rails world has number of cool gems for managing DB, please use any of them to manage your new shiny app.
