First year of Marketplace Pulse

First year of Marketplace Pulse
Amazon sales topped $30 billion last quarter. Yet most customers are oblivious to the fact that when buying from Amazon they are likely not buying from Amazon itself. Instead they are buying from thousands of small sellers on those platforms. It was reported that 49% of the Amazon’s $30 billion figure came from marketplace sellers. That’s $15 billion in sales last quarter from companies no one has heard of.

I almost took my laptop to the summit of Mont Blanc
This was going to be about how I took my laptop to the summit of Mont Blanc and did some work way up there. After writing code for 1,000 days straight it looked like an epic next thing to do. Unfortunately we failed to summit.

Can you buy your own mayonnaise?

Can you buy your own mayonnaise?
Hampton Creek, the maker of vegan mayonnaise called Just Mayo, has come under scrutiny by regulators for its business practices. Founders ran an undercover project to buy up their own products from stores, thus increasing the sales numbers. I was shocked to read how surprised media acted - this is getting done online every single day.

China’s incredible mobile ecommerce growth

China’s incredible mobile ecommerce growth
Alibaba recently reported Q2 2016 earnings - 75% of all merchandise sold was bought by mobile users. This is a huge number. It was barely 7% in 2013. In comparison, only 25-30% of the US online retail sales are done on mobile. When considering all China’s ecommerce platforms including JD.com and others, more than a half of ecommerce sales are made with mobile devices. It is expected that by 2019 that number will rise to at least 70%.

Jet.com was an obvious acquisition for Walmart

Jet.com was an obvious acquisition for Walmart
The problem Walmart has is that it is trying to grow two different businesses, brick-and-mortar retail and ecommerce, under one roof. This internal competition is a big issue. It’s hard to beat Amazon, who has been focused on one thing for years, while having to battle in every meeting. So where Jet.com comes in? It’s a focused company first. It’s a brand which has no brick and mortar history second. It’s a stellar team third.

Being able to code is not enough

Being able to code is not enough
I’m based in New York, a city where developers get paid some of the highest salaries in the world. If I’m going to hire someone here, I want way more than being able to build features. For that, I can outsource to a much cheaper country and get a similar result. Instead, I want to invest into someone who can deliver value with code being just one part of it.

Why I deleted your CV

Why I deleted your CV
I’ve been doing some hiring over the past few weeks and the amount of applications I discarded after 2 minutes of just scanning a CV shocked me. Probably 90% went straight to trash.

I stood in line for 3 hours for the new Tesla Model 3

I stood in line for 3 hours for the new Tesla Model 3
At 9 am on March 31st Tesla stores opened across the US, and many other countries, to take reservations for a car. The price was $1,000 for a ticket to be able to buy one in a few years. I went there to check out the scene at the west coast stores, and was pretty damn shocked to see close to a thousand people show up.

From PHP to Machine Code

From PHP to Machine Code
I recently gave a talk at a few conferences titled "From PHP to Machine Code". It explains how compilers and interpreters work in general, where are the performance gains to be found and how I applied all of that to build PyHP. PyHP is a little toy project which showcases the basics of taking source code of a programming language and executing it.
