"Every few weeks, Rawn Shah, our reviews editor, delivers a handful of timely news and product briefs. This month he looks at Linuxlab servers, MathSoft's S-PLUS package, Wolfram Research's Mathematica program, API Networks's CS20 dual processor, and ZeroG's InstallAnywhere Enterprise Edition."
"Linuxlab (not to be confused with another company, Linuxlabs), announced new 3-in-1 and 4-in-1 servers that fit three and four separate, small-footprint server systems into a 1U height chassis. Each server is a complete computer with its own hard drive, processor, memory, network interface, and power supply. The 3-in-1 units can support from 6 GB to 73 GB of disk storage, with up to 512 MB of RAM and Intel Celeron processors. The 4-in-1s can handle up to 20 GB of disk storage. Those kinds of servers, with multiple computers in a box can provide redundancy and load balancing in a single unit, given the proper software. By putting all computers into one 1U unit, you can theoretically fit about 128 separate computers on a standard relay rack using the 3-in-1 model and 160 using the 4-in-1s."
"MathSoft has released a Linux version of S-PLUS -- a statistical data mining package that analyzes large sets of numbers such as Web traffic, sales numbers, and virtually anything else numerical. It offers basic statistics such as correlations, cross-tabulations, probabilities, quartiles, densities, and random number generation, and then moves on to hypothesis and confidence testing, regressions testing, variance analysis, nonlinear and nonparametric regression testing, tree models, smoothing, multivariate analysis, cluster analysis, and much more. Here's a chance to put those years of college statistics classes to good use and study your company's sales behavior."
