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!

Things I wish I knew 10 years ago:

- it's okay to be yourself
- exercise more often
- invest in relationships
- importance of eating healthy
- money isn't everything
- learn for pleasure
- take the time to be in nature
- put aside technology more often

There has been speculation that changes to the way the internet is implemented will be rolled out to allow access only to authorized sites.

Some think this is impossible

I'm here to tell you it is not, and very likely.

Allowing access only to white listed IP addresses is easy.

The vast majority access the internet via their Internet Service Provider, and ISP's can easily block client access to any IP address they choose.

China has been doing this for years.

This is how firewalls work, and is much lower level than DNS blocking.

I would imagine this will be rolled out to 'Combat the ever growing threat of Cyber Attacks'.

Most people only use a few thousand services like Twitter, Facebook, Amazon, Google, Microsoft, TikTok, Snapchat, Instagram, Reddit etc, Walmart, Costco, Tesco, Morrisons etc. as it is.

It will be easy over time to require 'legal registration' for any and all other services and sites.

We already took a step toward this years ago anyway, so this is just the logical next step.

As 5G technology is rolled out in your city, more and more control is being introduced at the street level, using what are known as 'Edge Servers'.

While making services faster to access, it also allows an additional layer of security and access control at the local level.

Facebook is a newstand. But no one can see which news Facebook is pushing to the top.

So we built an app for that called #CitizenBrowser. Our first finding: the sharp impact of Facebook’s political ad ban reversal in the Georgia Senate elections.
https://t.co/GZNdwZOlHW /1

This is the first report from our #CitizenBrowser project. There will be many more to come. But first, I want to tell you a bit about how we did it because it’s the most ambitious thing we’ve ever done @themarkup – and we do a lot of ambitious projects. /2

#CitizenBrowser grew out of conversations @suryamattu and I had about how to audit Facebook. We had both worked on browser extensions to collect data from Facebook, but FB always threatened to shut those down, just like their recent threats against the NYU AdObservatory. /3

But the bigger problem is that browser extensions don’t capture most FB activity. Most people use FB on mobile and browser extensions only work on desktop or laptop computers.

So one night, late at the WeWork, @suryamattu said to me: “We’ll have to build our own browser.” /4

“No way,” I said. “That’s insane.” But slowly, I came around. Here’s why: browsers are good at running in the background. Users could log into FB once through the browser and never use it again.

Then we wouldn’t be monitoring users. We would only be monitoring their feed. /5

What are the implications of using hacked data for research?

A short thread inspired by the fact that, before AWs took it down, #Parler was extensively hacked and user data was leaked.

The #Parler dataset seems crazy interesting for doing research, and my first reaction after the breach was to shre it with other #CompSocSci ppl.

However, I started having second thoughts, so what follows is to organize ideas and have it somewhere I can look back to.

2/n

Generally speaking, as far as the ethics of research goes a good advice would be to handle hacked data with caution.

First of all, there's an issue of quality. Data might be altered or incomplete, and the source cannot be considered accountable (assuming src is anonymous).

3/n

Secondly and more importantly, a researcher using the data would probably be violating users’ consent and acting against the data collector's will.

Finally, users’ privacy is at stake, since researchers could see material that users didn’t agree for other people to see.

4/n

Sharing private information without consent might put people at risk of harm.

This is all the more true in cases such as the #ParlerHack, where the leaked information is of particularly sensitive nature, and there’s a high risk of unintended consequences.

5/n

If you're looking at GA EV data and thinking maybe the reason D turnout looks strong relative to 11/3 is because after 2 months of Trump/GOP officials trashing mail-in ballots GOP voters are ditching it for E-Day instead...

Boy do I have some mindblowing statistics for you...

I compared the current mail-in voting tallies for each Congressional District against November mail-in votes for those districts.

The statewide figure currently sits at 62%. Guess which district leads the state?

You guessed it!

GA-14 at 69%. Marjorie Taylor Greene's district.

#2 is GA-8 at 68%.

Jody Hice of "I'm joining Marjorie Taylor Greene in her effort to throw out the Electoral College vote" fame.

GA-9 (Doug Collins) is above the state average at 64%.

IF Republicans were ditching absentee balloting en masse to vote on Election Day, you'd expect to see it by now. But the early *in-person* voting totals are what's actually lagging, not mail-in voting.

Pardon the sloppy spreadsheet, but those last 4 columns are what I'm looking at. The last one in particular.

I was on @alexandermats show on ET Now yesterday, to discuss Facebook and Google vs Australia when it comes to News content, and how they've taken different approaches.

The key question: can this happen in India?

A thread 👇

1/

1. What's going on?
A proposed News Media Bargaining Code released by the Australian competition watchdog forces Google and Facebook to enter into arbitration with news publishers to decide a price for News on their platforms.

Price for Google to surface news. For users to share on FB.

2. Power imbalance: Australian competition commission believes there's a power imbalance between News publishers and social media platforms. This is true.

3. Google has done a deal with Rupert Murdoch's News corp

3/

and is now offering it “significant payments” for featuring it's publications in its News Showcase. This is a bad precedent in my opinion. Microsoft waded into this debate and supported what Australia was doing.

Why is this bad?

4. There's no compulsion: Google doesn't need to index news. Users want news and Google prioritises news on search results anyway, but publishers can prevent Google from indexing using their robots.txt exclusions. No one is forcing publications from being indexed.
