  How deep should unit test go?

There is a question on Stackoverflow which says "How deep are your unit tests?". It is asked by a guy named John Nolan. The question is not too new, but what catches me is the Best Answer given by Kent Beck, who is the creator of Extreme programming(XP) and Test Driven Development(TDD). Let's look at the question first. The thing I've found about TDD is that its takes time to get your tests set up and being naturally lazy I always want to write as little code as possible. The first thing I seem ...

  How I Became a Programmer

I posted a very brief response to a post on HackerNews yesterday challenging the notion that 8 weeks of guided tutelage on Ruby on Rails is not going to produce someone who you might consider a "junior RoR developer." It did not garner many upvotes so I figured that like most conversation on the Internet it faded into the general ambient chatter. Imagine my surprise when I woke up to couple handfuls' worth of emails from around the world asking me what I did, how I did it, an...

  Redesigning the Technical Hiring Process

Since my last post on technical interviews, I’ve been fairly involved in hiring at Pulse as we grew our team from 6 people when I joined last November to 14 full-timers. In my previous post, I suggested that technical interviews, in the conventional sense, are not especially effective (by technical interviews, I mean the traditional 45 minute coding-at-a-whiteboard and algorithm puzzlers interviews). Those do a great job of telling you how well a candidate is at acing those types o...

  10 Tools Every Software Developer Should Use in 2018

The main problem I noticed about most programmers is that even though they know about latest software development tools, they never really spend significant time to learn them well. As a programmer, I always try to learn new tools and latest technologies. At the same time, I also look to improve my knowledge of tools which I have been using for many years. Whether you're a front-end developer, full-stack programmer or part of a DevOps team, you should familiarize yourself with the latest develop...

  Why isn't all internet traffic encrypted?

The biggest problem is that you must be able to verify that you're encrypting to the correct key. Without it, encryption would be practically useless, as anyone could perform a man-in-the-middle attack on the connection and remain undetected.In typical SSL/TLS, as well as other protocols using X.509, this verification is performed by "certification authorities", which are explicitly marked as "trusted" by web browsers and operating systems. Unfortunately, these CAs usual...

  Lessons from the Trenches

I believe that making a game is part art and part science, so it's no wonder that managing a game project is also part art and part science. Clearly if it was all science then the industry would get a collective F for not having made any significant progress over the last decade - all one has to do is just glance at the published postmortems to see that the same patterns are repeated over and over.A game has to be fun, engaging, grab users in the first two minutes and also keep their a...

  Disgusting programming language list

To avoid arguments among different programming languages, this ranking only covers the opinions from programmers with multi-language experience. Also it doesn't mean the language is not good if the language is on the list, it just means those developers don't like some features of the language. Below ranking is summarized from Quora、Stack Overflow and Hacker News. 10. Python Reason : It uses code indent to define block level scope, why not use curly braces? It also uses massive colons and ...
