Articles on Linux, the open source operating system
In the mid 1990, I came to know of a fungicide being sold under the UNIX name.
At the time, I was working in Saudi Arabia for AT&T after its acquisition of NCR, and the general manager called me in to ask about this matter.
I told him that from what I know, trademark law does not cross domains. This means the use of UNIX in domains other than computers is permitted.
I send that info to the late Dennis Ritchie, the father of UNIX, and he put it on his site under Other UNIXes.
After upgrading from Mandrake Linux 10.0 to Mandriva Linux LE 2005 10.2, I found out that there is a serious issue with either Mandriva or with kernel 2.6.11.
This article describes the issues faced upon upgrade, adn how to work around them.
In February 2005, Mandrake Soft of France and Conectiva of Brazil, announced that they merged. Shortly afterwards, in April 2005, they announced that they are changing their name to Mandriva. Then they released Mandriva Limited Edition 2005 (LE2005) which is what Mandrake 10.2 should have been.
Since I have several machines at home, all running Mandrake, it was time to start the annual upgrade to stay current.

Linux is an open source general purpose operating system. Over the years, several people have used it in embedded systems. Now, Linux is in PDAs, Cell Phones, Routers, MP3 Players, Set Top boxes, and much more.
This article provides a wealth of information on the use of Linux in embedded systems.
One often comes across objections to using free software in commerical packages. These objections are often not based in reality but rather misperceptions, and FUD (Fear, Uncertanity and Doubt).
In this article, I will try to explore these objections, and counter them by facts.
When I tell people that I have six computers networked at home, they are often taken aback. But really really each one does have a certain function, and is used daily. Yes, I know, I am a techno-nerd. Get over it.
Recently, broadband internet has become so common that the use of modems has dropped dramatically. It has been many years since I had to configure a modem on a computer, let alone do so on Linux. However, modems do still have their uses. I bought a used 3COM 5610 PCI modem in order to be able to fax from Linux, and had to relearn how to configure a modem on Linux again. So, here is what I did.
As my home network expands, the time I spend doing administration tasks on it increases. As machines are added, I am required to add users to each machine, and mount directories so they are backed up on the server. By implementing autofs the problem of users' directories is solved. For users, I decided to implement NIS to centralize user administration.
One of the great things about UNIX and Linux is that they were built from the start to be multitasking and multiuser operating systems.
As networking became faster, new additions were done that was also multitasking and multiuser, such as the network file system, or NFS.
OnStep is a full featured telescope controller. A low cost controller based on the STM32 Blue Pill was created by myself. You can order kits for building your own, as well as a Smart Hand Controller.
