  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...

  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...

  The Reality

Everyone loves to talk about benchmarks. AMD’s Andy Parma recently wrote a blog that covers the top performance scores for the AMD Opteronâ„¢ 6200 Series processors. As marketing professionals, of course that’s what we talk about. What’s important to look at is the reality as well – what customers are actually purchasing. When you drive past car dealership, you’ll always see the fancy red sports car prominently displayed. It draws people in â€â...

  Why PHP Was a Ghetto

Note: I wrote this over a month ago, but decided not to publish it until now.I was talking with the Co-founder of a pretty cool start-up in DUMBO the other day about why the non-PHP development world generally has such disdain for PHP and the community surrounding it. He brought up an interesting point that stuck with me, largely because I hadn’t heard it before.If you’re unaware of the usual beef most developers have with PHP, it tends to revolve around:Ug...

  How to create a language in one day

About a year ago I worked on a very interesting project which involved creating a unique world with all its history, people, physics, metaphysics and so forth. I like fictional worlds that are thoroughly created and I have always marveled at people like Tolkien or Richard Garriot who go such great lengths and even create languages for their worlds. I have since many years felt that it would be awesome to create my own language and I’m probably not alone in feeling that.When I started stud...

  The Death Of The Spec

Earlier today, my colleague Matt Burns wrote a post noting that most tablet makers may be largely failing because they’ve sold their soul to Android and are now just in the middle of a spec war, which no one can win. I’m gonna go one step further in that line of thinking: the spec is dead.There have been a few key stories from the past couple of weeks that highlight this new reality. Barnes & Noble unveiled the new Nook Tablet. Consumer Reports looked at the...

1. Inability to reason about codeReasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is.SymptomsThe presence of "voodoo code", or code that has no effect on the goal of the program but is diligently maintained anyway (such as initializing variables that are never used, calling functions that are irrelevant to the goal, producing output that is not used, etc.)Executing idempotent functions multiple times (...

  About .NET memory leak--GC,Delegate and weak reference

Memory leak is always a headache for many programmers, the situation is much better now in some languages which have GC mechanism, but still we may face some memory leak issues when we write programs. 1. What is memory leak? Memory leak is not that the memory chip is broken. In short, it's about that the memory requested is not released at the expected time as an expect way.
