After our foray into DHCP options, we are ready for the last piece of the puzzle — actually sending and receiving data on a socket. First, we need to encode the high performance receive pattern. I’ve decided on an async…
Let’s do DHCP: options
Last time we built our DHCP buffer with header fields. For a fully formed DHCP message, we also need to support DHCP options. Each option has a tag byte specifying its type, a length byte, and a number of data…
Let’s do DHCP: intro
We’ve been talking about high performance datagram scenarios but have so far used a contrived sample of sending mostly fixed size strings — not so realistic. That will change today, as we turn to one of the more famous datagram…
Building an adventure game: part 4
Welcome to the fourth and final installment of my adventure game saga. We made it up to Day 15 last time. Let’s finish this up now. Day 16 I don’t like that the method to add an item to a…
Building an adventure game: part 3
I last left off on Day 8 of my adventure game project. We continue from Day 9 today. Day 9 After warming up with a simple rename, I decide I don’t like how TextConsole and InputLoop interact. If I want…
Building an adventure game: part 2
Previously, I recounted day 1 of my adventure game project. Let’s continue. Day 2 This was a short day. First I observe that it isn’t really necessary for the caller of Game to pass the MessageBus, so I change that.…
Building an adventure game: part 1
I have written before about my early experiences with text adventure games and about how I built a GW-BASIC translator to convert one such example game to C#. It was a fun challenge but was admittedly more of a compiler…
Find the issue: tainted strings
In a previous post, we introduced a wrapper object for some method parameters: In terms of encapsulation and validation, this was a marked improvement. But there is one critical issue here. Let’s zoom in on the auditMessage parameter. In context,…
Find the issue: unbounded growth
Last time, we implemented a MyCommands class to keep track of commands invoked by the MyCommandsController. Here is the MyCommands as we left it: What possible issues do we have here? The first one that comes to mind is the…
Exact square roots (continued)
Last week, I introduced a data structure kata involving exact square roots. At the time of that writing, I had implemented a RootTerm struct which could represent real and imaginary square roots. Today we’ll pick up where we left off…
