  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...

  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...

  Some Thoughts on Twitter's Availability Problems

As a regular user of Twitter I've felt the waves of frustration wash over me these past couple of weeks as the service has been hit by one outage after another. This led me to start pondering the problem space [especially as it relates to what I'm currently working on at work] and deduce that the service must have some serious architectural flaws which have nothing to do with the reason usually thrown about by non-technical pundits (i.e. Ruby on Rails is to blame). Some of my suspicions ...

  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...

  FTP Must Die

The File Transfer Protocol (FTP) is specified in RFC 959, published in October 1985. The attempt in this specification is to satisfy the diverse needs of users of maxi-hosts, mini-hosts, personal workstations, and TACs, with a simple, and easily implemented protocol design.That's from the introduction. Does anyone here know what a TAC is? I don't. I had to look it up, since the acronym wasn't even expanded in the RFC. It took three tries in Google, and I finally found it in some obscur...

  Guide on recovering data in MySQL

In our daily work, there might be mistakes made which got some data or even databases deleted in MySQL. If this happens on production, it would be a nightmare. In case this happens, normally DBA would jump in to save the world. And they would try to recover the data from the backup if there is any. But if there is no backup, then the show stops. Hence database backup is necessary on production environments to avoid such awkward situation. Also normally in MySQL, binlog should be enabled as well ...
