  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...

  Building a Modern Web Stack for the Real-time Web

The web is evolving. After a few years of iteration the WebSockets spec is finally here (RFC 6455), and as of late 2011 both Chrome and Firefox are SPDY capable. These additions are much more than just "enhancing AJAX", as we now have true real-time communication in the browser: stream multiplexing, flow control, framing, and significant latency and performance improvements. Now, we just need to drag our "back office" - our web frontends, app servers, and everything in between into this cen...

  Google Dart? Don’t bet against JavaScript

Procotols, programming languages and operating systems all compete in a constantly evolving software ecosystem. Out of that ecosystem only a few technologies truly have staying power and survive over the long term. An example? How about Ethernet? It’s been a survivor over the last thirty years despite existing in a constantly changing landscape that’s been populated with many worthy competitors. Ethernetâ€â„...

  Hail the return of native code and the resurgence of C++

Programming language trends come and go. First, Java is the hot new language, then it's Python, then Ruby steals the limelight, then it's back to JavaScript. But the latest language darling is probably the last one anyone expected. Believe it or not, 2011 could be the year of C++. Last week, the latest version of the ISO C++ Standard was approved by unanimous vote. It's the first major revision of the language in 13 years. Now officially known as C++11, the new standard introduces features desig...

  RAM is the new disk...

Jim Gray, a man who has contributed greatly to technology over the past 40 years, is credited with saying that memory is the new disk and disk is the new tape. With the proliferation of "real-time" web applications and systems that require massive scalability, how are hardware and software relating to this meme? Tim Bray, in his discussions about grid computing before it became such a hot topic, pointed out how advances in hardware around RAM and networking were allowing for the creation...

  Clojure & Java Interop

About a year ago I got a phone call asking if I wanted to join another team at DRW. The team supports a (primarily) Java application, but the performance requirements would also allow it to be written in a higher level language. I'd been writing Clojure (basically) full-time at that point - so my response was simple: I'd love to join, but I'm going to want to do future development using Clojure. A year later we still have plenty of Java, but the vast majority of the new code I add is Cloj...

  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...

  Hey kids, just say NO to programming !

Cory Doctorow's latest talk 'The Coming War on General Purpose Computing' really puts things in perspective about life in the 21st century. This got me thinking more about functional programming languages and how they are related to the intentional limitation/crippling of turing machines by industry and government. What if Stallman is right about the intentional efforts to limit freedom of information ? What if it's even worse than we all think it is ? In relation to functional languages ...

  Open Source (Almost) Everything

When Chris and I first started working on GitHub in late 2007, we split the work into two parts. Chris worked on the Rails app and I worked on Grit, the first ever Git bindings for Ruby. After six months of development, Grit had become complete enough to power GitHub during our public launch of the site and we were faced with an interesting question:Should we open source Grit or keep it proprietary?Keeping it private would provide a higher hurdle for competing Ruby-based Git hosting sites, givin...
