Сегодня пятница, а значит самое врёмя, чтобы запустить 1 фав=1 факт о моём компьютерном детстве середины 90х, о первых программах, победах и поражениях. Ретроностальгии вам нанесу. Буду стараться, поэтому не жалейте ретвитов.
1. Начать нужно с начала. Жил я себе без компьютеров и жизнь была кайфовая - жуков ловить, на велике гонять. Пока в году так ~95м не пришёл к своему однокласснику домой и не увидев впервые компьютер. ГОСПОДИ! До этого я же как-то жил без компьютеров, а теперь без них ЖИТЬ НЕ МОГ.
2. Справедливо упомянуть, что со школы я не помню ни одного стихотворения. Зато технические детали, спецификацию и характеристики моего первого компьютера я, наверное, запомню на всю жизнь. И на смертном одре правнукам ради хохмы зачитаю, а они такие ВО ДЕДА ГОНИТ ВАЩЕ ПОЕХАЛ.

It took me ~4 weeks, maybe 35 hours/week, to make. However! I spent 2 weeks just watching courses, so 2 weeks of solid work, I think is fair to say.
It's made with #angular, #ngrx, #express, #mongodb, #mongoose, & #love.
Here's the story. (cont'd) #programming

The goal was to make a recipe/grocery list app. We have a weekly menu, and I'd want to select recipes and just get a grocery list automatically.
Sketching things initially helped a lot. Layout was never a problem, because I love #materialdesign and I'm stuck in the 90's...

#ngrx was definitely the trickiest part. @DeborahKurata & @dunchunter's course on #pluralsight is amazing, and everyone should watch it (if they need to work with ngrx, obvs).
Did I need ngrx? No. This could have been solved with services. But, I wanted to learn.

An article about what is Functional Programming (FP), and how does it differ from Object Oriented Programming (OOP) ?
Note that both these paradigms are used in R, and interact with each others.

Here’s the definition of what FP is :
- Programming == creating function
- Functions returns values computed from arguments (and only these)
- A function has no side effect

(1/5) I grew up in the Programming Languages research community and have recently begun attending Machine Learning conferences. One perspective that I don't see much in either community is that #MachineLearning is a form of #programming.
(2/5) PL/formal methods researchers tend to think of programs as engineered objects, and study abstractions/tools for principled engineering. But the big assumption here is that you can formalize your goals and the world in which your programs run. That's not always realistic.
(3/5) In contrast, #MachineLearning lets programs be "found" objects. "I don't have a full spec for my program and can't write the code myself, but here's some data on what it does. Discover it!" This is still #programming, albeit done inductively rather than deductively.
High level #python #tutorial thread:
Python is a high level language that runs bytecode in its virtual machine.
Everything is an object.
It supports OOP up to multiple inheritance and functional programming.
Typing is polymorphic - duck typing is preferred

A Python script is a file with a name like name.py - we indent at four spaces (it matters), comments (after #) don't execute - and is typically written like:
def main(): # function
print("Hello world")
if __name__ == '__main__': # then entry point
main()
def main(): # function
print("Hello world")
if __name__ == '__main__': # then entry point
main()
A module is a reusable script:
"""this is a docstring at the top of the module - gives help on the module"""
import this # do imports at the top
def main(): # main at top or bottom
"""functions get docstrings too"""
if __name__... always at the bottom, assumed from now on
"""this is a docstring at the top of the module - gives help on the module"""
import this # do imports at the top
def main(): # main at top or bottom
"""functions get docstrings too"""
if __name__... always at the bottom, assumed from now on
