Why I Quit My Job to Start a Tech Company
Back in November of 2006, before NY Mag and TimeOut put startups on the cover, before the “tech bubbleâ€, before Twitter and Foursquare were popular, before working at a startup in NY was considered a reasonable thing to do, I was a private equity investor for a $1.6 billion fund called Quadrangle Group. It was just my third year out of college and I made a little over $250,000. For a Brazilian immigrant who spent most of his childhood kind of worried he would have to do physica...

Key challenges in Agile implementations
7Share6inShareAgile methodology was supposed to be a solution to solve all of our problems. But it looks like it’s not. Some issues appear when companies start to implement Agile in their organizations. A research has been done on seventeen companies using Agile methodology (People over processes: Key people challenges in Agile Development). Authors chose nine of the most often reported issues. I’d like to focus on four, in my opinion, most important. #1 Developer...

Coding tricks of game developers
If you've got any real world programming experience then no doubt at some point you've had to resort to some quick and dirty fix to get a problem solved or a feature implemented while a deadline loomed large. Game developers often experience a horrific "crunch" (also known as a "death march"), which happens in the last few months of a project leading up to the game's release date. Failing to meet the deadline can often mean the project gets cancelled or even worse, you lose your job. So w...

What programming languages should I learn?
Since I started this blog, I have gotten quite a few emails asking me “What programming languages do you recommend for X?†I often finding myself writing something along the lines ofI would honestly recommend python. Something about me being biased because I know and love it. Usually say something about the competing technology with a back handed insult. Also if they are starting out I would recommend a language that enforces better OO (Object Orientated) practic...

The mystery of Duqu Framework solved
The Quest for Identification In my previous blogpost about the Duqu Framework, I described one of the biggest remaining mysteries about Duqu – the oddities of the C&C communications module which appears to have been written in a different language than the rest of the Duqu code. As technical experts, we found this question very interesting and puzzling and we wanted to share it with the community. The feedback we received exceeded our wildest expectations. We got more than 200...

A Python Optimization Anecdote
Hi! I’m Pavel and I interned at Dropbox over the past summer. One of my biggest projects during this internship was optimizing Python for dynamic page generation on the website. By the end of the summer, I optimized many of dropbox.com’s pages to render 5 times faster. This came with a fair share of challenges though, which I’d like to write about today:The ProblemDropbox is a large website with lots of dynamically generated pages. The more pages that are dynamically generat...

In-memory key-value store in C, Go and Python
Subtitle: Wow Go’s net library is fast On paternity leave for my second child, I found myself writing an in-memory hashmap (a poor-man’s memcached), in Go, Python and C. I was wondering how hard it would be to replace memcached, if we wanted to do something unusual with our key-value store. I also wanted to compare the languages, and, well, I get bored easily! The code is on github as Key-Value-Polyglot. Each version implements enough of the get and set commands from the mem...
Mock Solutions for GoLang Unit Test
In Go development, Unit Test is inevitable. And it is essential to use Mock when writing Unit Tests. Mock can help test isolate the business logic it depends on, enabling it to compile, link, and run independently. Mock needs Stub. Stub function replaces the real business logic function, returns the required result, and assists the test. I involved the related test code for Controllers while writing Kubernetes Operator recently, and there would be mocks for GRPC and HT...
