Graphical signal calculator available under GPL

Author: JT Smith

Arnaud LAPREVOTE writes about SigLab, a graphical signal calculator: The Free&ALter Soft company is ditributing its softwares under the GPL licence, among others SigLab, that can be freely downloaded from the CVS Sourceforge server.
Introduction
SigLab is a calculator specially designed for working on signals. You may load, save or generate signals, do various operations on and between the signals (addition, …, log, abs, sin, …, filtering, convolution, fft, correlation).
SigLab was designed for being able to handle results of simulations or measurements. It means it can handle signals with millions of points in just keeping in memory a small piece of each signals. However, to keep good performance, it caches in memory portions of the signals.
SigLab was specifically thought for Ptolemy users. You will then find stars ready to use. SigLab will start at the end of the simulation and show all signals that you asked.

Requirements
You need a working copy of SciLab 2.5 beta for having SigLab working. You also need tcl/tk 8.xx (just tested on 8.0). SigLab was tested under Solaris, Windows and Linux.

Licence
SigLab is now under GPL. Siglab is originally a sponsorware. It was developped thanks to the support of the C2R (Research Center on RadioDiffusion and RadioCommunications) of TéléDiffusion de France (a subsidiary of France Telecom) and thanks to Philips Semicondictors Rennes. You can thank these companies for having accepted to share the tools they use with everybody. We are still looking for sponsors to improve SigLab (improvement of integration with SciLab, filter design interface, management of multidimensionnal signals, …).

Implementating security in FreeBSD

Author: JT Smith

DaemonNews.org has an article about general security issues for FreeBSD. “The funny thing about security is that we actually have quite a lot of it in the UNIX paradigm. We have users, groups, chroot,
secure levels, and jails. The only problem is that we don’t use any of it by default. Most services are run as root – pop3, ftp,
ssh, ident, sendmail, talkd, named, ntpd, and even the ones that aren’t, such as apache, barely touch the first layer of
security offered in FreeBSD: each runs as its own user and group but doesn’t bother with anything else. Even when
programs such as named have security-minded options, they tend to not use them by default.”

Crackers with that honey?

Author: JT Smith

BBC: “A decoy computer network set up to record every
attempt to crack it open and subvert it has revealed just
how active and determined malicious hackers have
become.

Statistics gathered by the
network show that computers
connected to the web are
scanned for weaknesses up
to 14 times per day and that,
on average, an attempt will
be made to break into a
net-connected computer
every three days.”

Author: JT Smith

Kirill Tikhonov writes: “Russian news site Compulenta has a story about new powerful supercomputer MBC-1000M launched in Moscow’s Joint Supercomputer Center. According to the Russian Minister of Industry, Science and Technologies, Russia now holds the third place among the world’s manufacturers of high performance supercomputers. Which means that all European countries and China were left behind. The peak performance of the system is 1 Tflops, the value that makes up the estimated performance speed of the human brain.”
