As I’m writing this, it’s the first time I’ve had hotel-provided Internet access since I arrived on Thursday. The reason I mention this is that it is, by far, the only negative experience that I’ve had at the first Clojure Conj. It has been the best programming conference I’ve been to in a long time. The amount of […]

Redis is a key-value store if you want to strip the idea down. A key-value store maps a key, usually a string, to some “blob” of data, and gives you the basic commands you need to manipulate them. There are a few things that I think make it interesting, however: Rich data structures Unlike some traditional key-value stores, like memcached, Redis […]

Today, in the New York Times, there was another article about how the US government wishes to make it easier to establish the National Panopticon. This follows a previous article that contained the amazing opening paragraph: Federal law enforcement and national security officials are preparing to seek sweeping new regulations for the Internet, arguing that their […]

So, what does it mean to put together ZeroMQ and Protocol Buffers inside of Clojure? What exists below is really just a quick thrown-together combination of a few sample bits of code from projects. This isn’t intended as a lesson in ZeroMQ, Protocol Buffers, or Clojure, but if you’ve got even a little bit of experience with a Lisp-ish language, […]

For most people, if they think about IP addressing at all, they see it as a 1:1 assignment of addresses to machines. This isn’t true though, either in theory or practice. A single machine can contain at least the following address types: IPv4 unicast — 192.168.1.10 IPv4 loopback — 127.0.0.1 IPv4 broadcast — 192.168.1.255 IPv4 multicast — 224.0.1.41 IPv6 unicast — 2001:DB8:0:0:0202:B3FF:FE1E:8329 IPv6 loopback — ::1 IPv6 anycast — 2001:DB8:0:0:0:0:0:0 IPv6 […]

Nearly 15 years ago, the IETF gave final approval to the next version of IP: IPv6. This came after several years of extensive research, prototyping and work by a lot of very smart people attempting to solve the problems facing the then-current version, IPv4. The problem is, in the intervening years, IPv6 has not been rolled out […]

Within the software development community, the term refactoring is used pretty frequently. Martin Fowler defines it as: Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure. The question for me is, what happens if we apply some […]
