- Where's the SPARCstation 10...?IMPRESSIVE Collection indeed, but I was disapponted that you had no SPARCstation 10. Knowing what a Geek I am, my wife bought a complete system for me on eBay (SPARCstation 10 with SM31 processor and 64 MB RAM, Monitor, Keyboard, Mouse and Solaris 7). I later inherited...

- Bring out your dead!
- One of most popular set of Photo Galleries that we do on TechRepublic is the Cracking Open series. In them, we take perfectly good pieces of technology and take them apart, displaying all the bits inside. Most of the time, they even still work when we put them back together!...

- Better coding with the Model-Glue:Unity ColdFusion application framework
- Model-Glue is a Model-View-Controller MVC framework for ColdFusion that was released in 2005. Model-Glue is what is known among software engineers and application developers as an event-based, implicit invocation framework. You use XML to declare event handlers, and these event handlers are called via a URL or form variable. In...

- Model Checking Networked Programs in the Presence of Transmission Failures
- Software model checkers work directly on single-process programs, but not on multiple processes. Conversion of processes into threads, combined with a network model, allows for model checking distributed applications, but does not cover potential communication failures. This paper contributes a fault model for model checking networked programs. If a naive...

- Advantages of XML as a Data Model for a CRIS
- This paper presents advantages of using a hierarchical, XML-based data model as the basis for a CRIS, as opposed to the relational model, which is currently recommended by EuroCRIS. The main benefits lie in the relatively easy way to model data, since there is no need to create and maintain...

- An Analytic Throughput Model for TCP NewReno
- This paper develops a simple and accurate stochastic model for the steady-state throughput of a TCP NewReno bulk data transfer as a function of round-trip time and loss rate. The model builds upon extensive prior work on TCP Reno throughput models but differs from these prior works in three key...
