SQL is the most common way to communicate with database servers and is supported by almost all database systems. Shell scripts make excellent wrappers for SQL queries. They are quick and easy, allow you to use shell variables to enter information into your SQL scripts, run scripts more securely than they all too often are, and even automate your scripts so they can work while you sleep.
Topics covered will include:
Tom Chapin has been hanging around Unix systems for decades, at AT&T for far
too many years and as a contractor for a few. He spent eight years teaching
Unix at AT&T Bell Labs. He has an inordinate fondness for shell scripting
and in demonstrating its many capabilities.
Monolith: Parallel Scientific Computing with a Linux Cluster
Progress in many areas of great interest in physics research, including some in high energy particle physics, general relativity, astrophysics, and solid state physics, are limited by the computational power available. The development of Beowulf clusters -- parallel computers based on commodity hardware and free software -- gives computional physicists an inexpensive way to make great progress in their research. In parallel computing, difficult computational problems are divided up among many CPUs to solve problems too difficult to solve on a single system.
The team that built a Linux cluster using PC hardware for the Washington University Physics Department will describe its design and construction, as well as the use of the cluster for simulations of quarks and gluons, the elementary particles inside the proton and neutron.
Michael Ogilvie is Professor of Physics at Washington University. He received his Ph.D. from Brown University in 1980. A native of St. Louis, he came to Washington University after postdoctoral fellowships at the University of Maryland and Brookhaven National Laboratory.
Travis Miller is a graduate student in the Physics Department of Washington University, and will receive his Ph.D. in August 2002. In September 2002 he will begin a postdoctoral fellowship at Indiana Univerisity.

Event Date: Saturday, April 13, 2002 at 12 noon to 5 PM Event Location: Advanced Technology Center 118 N. 2nd Street St. Charles, MO 63301 Admission: Free The St. Louis Linux Users Group announces their 4th Linux InstallFest. At this event, experienced Linux users will assist those who wish to install and learn about Linux. Anyone who wants to know more about Linux is welcome to attend. Over 40 people attended the previous InstallFest (October 2001). In most cases, all you will need to bring is the computer itself. We will provide the Super VGA monitors, PS/2 keyboards, and PS/2 mice. If you have older or non-standard hardware, you should bring it along. If you're not sure, bring everything to be safe. Free copies of popular Linux distributions will be provided on CD. If you have a specific distribution that you want to install, you can bring it along as well. Be sure to back up your system before you bring it in, as the installation process may overwrite existing data. The InstallFest is sponsored by the Economic Development Center of St. Charles County. The EDC will be providing space for the installations, food and beverages. They have a high-speed Internet connection that you will be able to connect to if you have an Ethernet card. Several members of the St. Louis Linux Users Group and other local groups will be present to assist with installations and configuration. If you would like to attend, please sign up on the web site at http://www.stllinux.org/InstallFest-4/installfest-register.html. (You don't have to register, but we would appreciate it.) If you can help out in any way, please let us know: http://www.stllinux.org/InstallFest-4/installfest-help.html For more information on the Linux InstallFest, see the web site or contact Fred Smith (firstname.lastname@example.org).
The 2002 Information Technology Expo, at the America's Center, runs 10:00am to 4:00pm, Wednesday/Thursday, May 22-23. For over a decade we have participated in this event. Once again we are building on the previous year's incredible show success, and sincerely hope you will join us. ITEC is our annual promotional event and we have several venues that will help to promote our various organizations as well as provide an opportunity to live up to our charter's vision of the promotion of Open Source/Open Systems as well as providing education in technologies. Please visit http://www.sluug.org/ITEC for detailed information on our participation. The site will be updated as information is finalized. Here are some highlights of our participation this year: -- Booth #603, directly adjacent to the Keynote theatre. -- Seminar Rooms #123 and #125 (see website for details) -- Miguel de Icaza, Keynote theatre, Thursday, May 23, 1:30pm -- IT Myths, An Associations Collaboration, two separate events -- Association theatre, Wed., May 22, 10:30am-1:30pm -- Keynote theatre, Thurs., May 23, 12:30pm There will again be in-booth demos both days, showcasing Open Systems and applications for the work place and home. Spread the word to your co-workers that the O'Reilly line of books will be available for purchase with show special discounting. This event allows us to maintain our status with O'Reilly and make available the excellent resource books at meetings. The online registration is improving and makes it easier than ever to show your support. With an added search available of previous attendance, you can simply update information instead of retyping it all. (Visit http://www.sluug.org/ITEC for details.) Don't forget, let them know you are attending because of an invitation from the St. Louis Unix Users Group. We look forward to seeing you there! ITEC Planning Committee.

There are two possibilities for using USB digital cameras and Linux, either USB direct or using USB Mass Storage architecture. If your digicam supports USB Mass Storage, you are more fortunate because you will find support directly in modern kernels for this. With USB Mass Storage, your camera will appear to the computer as direct storage device, such as a floppy. CDROM or hard drive connected over USB. This month I will describe USB Mass Storage since it is quite a bit simpler. Next month I will discuss gPhoto and the Kamera software applications to talk to your camera. The camera I'll use for this discussion is a HP 315 which can be had around town for about $180 and online for about $165.
First I will assume you are using either a 2.4 kernel variety or a 2.2 that has USB support backported. For the next part I'll also assume you are running the Gnome desktop manager, but similar steps will apply to KDE. The trick to making this work is to understand that in Linux, storage things like to think they are SCSI devices even if they are not. That means we will be using one of the /dev/sdXX devices. The other piece of wisdom is that USB cameras, to appeal to the widest audience, want to pretend they are DOS disk drives.
First create a mount point to attach the camera's storage device. I like /mnt/usb/cam1 for this. Next, while the camera is powered off, attach the USB cable to the camera and an open USB port on your computer. Next power up the camera as if you were going to start taking pictures. Most cameras will indicate that they are talking to the PC via a status LCD. Finally, wait a few seconds to allow the PC and the camera to recognize each other and then mount the camera on your mount point.
For example, as root: # mkdir /mnt/usb # mkdir /mnt/usb/cam1 ... attach camera and power it up. # mount -t vfat /dev/sda1 /mnt/usb/cam1
You might see an LED on the camera flash when the memory is being accessed. Now fire up the Nautilus file manager and type /mnt/usb/cam1 into the address bar. Drill down the directory structure until you see a bunch of JPEG images (usually numbered something like im000001.jpg, im000002.jpg etc.) In Icon mode, Nautilus will display these as thumbnails. You can then copy these to your drive. You can then use the Gimp to touch them up by editing the brightness and contrast and save them back or compress them.
If you wish to delete the images from your camera, you must be root to do this. This is because you can't change the permissions of the directories on the device.
As root with a HP 315 attached: # rm -f /mnt/usb/cam1/dcim/100hp315/* When you are done, unmount the camera and power it down and disconnect. As root: # umount /mnt/usb/cam1
You can also copy pictures back to the camera as root, but these must be in the same format the camera understands. In other words you can't copy arbitrary JPEG images to the device, even if you name them using the camera's naming conventions. They will show up in the LCD display but probably be blank or exhibit another error. However, you can treat the media card as just another disk and use it to store stuff like MP3s or documents and take it between systems. I'm pretty sure this will work in Macs, Linux and probably Windows.
Next month I describe using your camera with popular Linux software such as gPhoto and the Kamera for KDE. We will also have pictures from the InstallFest and I will describe how to paste them up to a web site.

Your imagination is your preview of life's coming attractions. -- Albert Einstein When I'm working on a problem, I never think about beauty. I think only how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong. -- Buckminster Fuller Some places I worked in the past had Employment Contracts that gave the company full rights to "... any intellectual property, inventions or creations made during the period of employment." I often thought that if I really wanted to quit and didn't care about a good reference, I'd take my camera to the local zoo and shoot several rolls of, er..., animal droppings, then lay out a book of photos of these, er... products of nature. And, since the company has all IP rights, put them down as the author. It'd all be worth it when HR got the pre-press of the glossy coffee table book of Products, by Joe's Software, with the big picture of a turd on the cover. -- dghcasp on Slashdot Pirating software is like stealing crack from a drug dealer and pretending that it makes you free from addiction. -- einhverfr on Slashdot [I assume he means proprietary software.] AAAAA - American Association Against Acronym Abuse -- Rob Fugina For any business which is now or might in the future be a competitor to Microsoft to use Windows XP or any other product requiring permission from Microsoft to operate is essentially malpractice. -- Michael Sims, WWWAC mailing list Shortest sentence in the English language: I am. Longest sentence in the English language: I do. "I bribed Congress" is not speech that should be protected under the First Amendment. -- Craig Buchek Leave it to a politician to increase the amount of cash he can receive, make it illegal to say he's a bad apple, and call it all Campaign Reform! -- Tim Dreste Alas, NT and Win2K allow any program to control any other; an unprivileged user can thus gain control of a privileged program and bend it to his or her will. Safeguards against such exploits have long been present in UNIX and were mentioned in Microsoft's recent DRM patent. (Ironically, Microsoft did not implement the commonsense security mechanisms it "rediscovered" and managed to patent despite long standing prior art.) -- eWeek, http://www.eweek.com/article/0,3658,s=1884&a=24761,00.asp
