Two years ago on a weekend, I built a tool to make it easier to evaluate Twitter accounts. Since then 36590 people used it to analyze 55390 different Twitter accounts.

Over the last months @mmkaradeniz and I made a new version. We launched it last night:

Google's interview system is not great but there are various reasons why it feels less than it is. Most candidates don't know what the goal of our interviews are. First rule, it is not about finding an optimal solution or any solution at all.

You are interviewed for multiple skills simultaneously. Cognitive skills, communication, leadership are a few to name. If the point is not finding a solution, then what is it? Let me explain.

Your interviewers try to understand what it feels like to work with you on a daily basis. An interview question is just a tool in achieving that, it is not there to specifically measure your skills on a topic but a tool to understand the depth of your thinking.

Before the interview starts, ask them what they want to get out of this interview. Good interviewers should already have a plan and a set of expectations. Ask them what you should do. Don't start coding yet. Ask them you should produce. Discussion, diagrams, pseudo code, code?

Then, start cracking the question. List whatever questions you think it is important to solve this question, ask your edge cases. Get to a point where you are discussing about pros/cons of the solutions. These steps are critical. Don't just start coding. Have a consensus first.

Why did I leave Google? A thread.

This thread is going to include quotes from Wired's "Three Years of Misery Inside Google, the Happiest Company in Tech" because I'm not a professional writer

When I joined Google, I fell in love with the company immediately. I was excited to come to work, not just for the technical challenges, but because I really felt I was making a difference and working for the good guys.

I spent 20% of my week working on an app that helped people find lost loved ones after natural disasters. I spent more free time speaking to students about technology and diversity. For an entire school year, I taught CS classes twice a week at a local low income high school.

The company was open. We had a weekly meeting called TGIF where anyone in the company could ask questions of, and raise concerns with, the execs. We got real answers.

you know how Atari called the Jaguar as a "64bit system", because it had two 32bit CPUs? (or because it had a 64bit bus, but let's not worry about that)
we should apply that logic to the current generation of consoles.
So the Switch is a 256bit console. It's the Nintendo 256.

The Xbox Series X? terrible name.
Better call it the "Xbox 512 Blu-ray".
like the Jaguar CD, the Sega CD... the good old days when consoles had their media type in the name.

Boringly the PS5 is also a Playstation 512 Blu-ray, because both of them are using the same AMD Zen 2 CPU.

The Switch one is weeeird. It's built on an Nvidia Tegra X1, which is an 8 core 64-bit CPU, so that should be 512, right?

Well... no. Four of them can't be used. And later documentation doesn't even mention them.

it's some weird system where the system-on-a-chip has four Cortex-A57 cores and four Cortex-A53 cores but only the A57s are usable?

Last weekend, I made a threat on the ongoing #SocialMedia shutdown in Uganda and some implications on the future of #internet & Uganda's #digital agenda.

The thread attracted a lot of engagement and questions. Tonight, I will share some final thoughts on the subject. (1)

Conceptually, social media sites are the largest on-boarding platforms for internet users in Uganda. Notably, Facebook, WhatsApp, Twitter, Instagram & Snapchat attract the highest internet traffic- which drives demand for other platform services e.g Google and Zoom recently.

So- when we talk about an "open internet", we mean the FULL resources of the internet. Any encumberance on selected applications has ripple effects across the entire network thus jeorpadizing standardization of internet/data transmission which is essential for innovation & growth

Furthermore, shutdowns hinder network interoperability (technical ability to plug/link one digital product or service into another product or service). Interoperability is the heart of the "Internet of things" eg business, devices, networks, services, e-govt, integration etc #IoT

Because the internet is a global resource, shutdowns enhance a digital divide (the gap between demographics and regions that have access to modern ICTs, and those that don't or have restricted access). Ironic that 3rd world countries have the highest number of shutdowns globally.
