  How often to change a job?

Those people who choose to change jobs once a year or a few times a year, please keep in mind that if you do not have your own business plans or your own start-up ideas. The choice you have now may be fatal to your future career development. After talking with many development managers, architects, product managers, and other friends, I find the greatest feeling of them is that the vast majority of IT people do not know what they do. From the interviewer's point of view, if you don't know what y...

  Python internals: how callables work

[The Python version described in this article is 3.x, more specifically - the 3.3 alpha release of CPython.] The concept of a callable is fundamental in Python. When thinking about what can be "called", the immediately obvious answer is functions. Whether it’s user defined functions (written by you), or builtin functions (most probably implemented in C inside the CPython interpreter), functions were meant to be called, right? Well, there are also methods, but they’re not very ...

  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...

  Reducing Code Nesting

"This guy’s code sucks!" It’s something we’ve all said or thought when we run into code we don’t like. Sometimes it’s because it’s buggy, sometimes it’s because it conforms to a style we don’t like, and sometimes it’s because it just feels wrong. Recently I found myself thinking this, and automatically jumping to the conclusion that the developer who wrote it was a novice. The code had a distinct property that I dislike: lots of ...

  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...

  The Number One Trait of a Great Developer

Maybe the best programmers aren’t those who spectacularly solve crazy problems, but those who don’t create them, which is much more silent. – Lena HerrmannWhen I look around at other companies hiring Ruby on Rails developers, I see them focusing on three major traits: Super-smart; Large community following; Deep Ruby knowledge. They’re all wrong. While these are great aspects in moderation, they all miss the number one quality of a fantastic developer: Judge...

  I'm Retiring from PHP

I am retiring from PHP as my language of choice for personal side projects and new programming ventures. This was not an easy decision to come to, but one that I think is necessary for my love of programming to continue. You see, I'm not only a programmer because I love programming, but because I can not do anything else. History It all started in 1999 when I was in 8th grade. The Internet was really starting to get interesting and I wanted to start programming. I had picked up...
