What's the coolest new tool/software you discovered in 2020?

Let's create Phineas using CSS in few simple steps😄

THREAD🧵

STEP 1. Create a head

create a triangle and rotate it so that it looks like a head

STEP 2. Create smile and ear

We have a pseudo elements in CSS, so we can create smile and ear using head::after and head::before

STEP 3. Create eyes

This is the most trickiest part because in order to make an eye we have to create

- One bigger white circle
- then a small black pupil inside white circle
- then a small white reflection in black pupil

Let's create a outer white circle first

STEP 3(I). Create a black pupil

We can create pupil using pseudo element

How should one approach System Design questions during an interview?

Here's the step by step guide:

🧵👇🏻

System design interviews are generally open ended discussions. There's no one right answer.

The main focus in this round is to see your thought process and whether you'll be able to design a minimal system keeping future scale in mind and by following the standard principles.

Know that many interviewers deliberately make it hard to see how you approach a given problem.

You cannot possibly design a complex system in 1-2 hours which engineers usually take months to years to design, develop and build.

So this is how you should approach this round:

1. Clarify the requirements: As mentioned earlier the questions are generally very open ended. So you need to ask a lot of question to set the scope clear for the discussion.

Example: "Design an application like Twitter"

Twitter has a lot of features like:
- Post tweet
- Home timeline
- Profile timeline
- Analytics
- Likes
- Retweets
- Following
- Bookmark
- Trending etc

You get the idea!
