looking forward to the 15th!

by Wes Allen

Hi gang, I'm looking forward to the 15th of January so I can finally say good-bye to Brother Bill on my iPAQ. I got a couple of questions..... Has anyone used the perl-script that syncs the ipaq and evolution? Other then the notorious, "Don't run this while Evolution is open" are there any other problems? Which CF wireless nics work with linux on the iPAQ. I'm seriously thinking that I'm going to get the cf-plus expansion pack and a wireless nic for my iPAQ (linux's true strength is networking, right?). So which one's work? And, sadly, how easy is it to reverse the process? On the off-chance that I can't stand OPIE as a working environment. I've read the howto, how hard is it in "real life." It might be fun to invite some of the people from the compaq lab to the meeting if anyone who worked on ipaq linux is based in the Worcester area....

Have you considered a Apple iBook or Powerbook? An iBook runs for about $1000 and PB's $2000. Compared to my Dell Laptop for work.. Apple has some nice hardware. I have an iBook 500mhz.. I was shocked how well Yellow Dog Linux ran on it. The speed difference over Mac OS X was very noticable. I also tried Mandrake PPC linux on it, not very impressed with it. Unfortunetly, the 20 gig drive I placed in the iBook fried, so all I have now is Mac OS X. The 10 gigs is too tight for a dual system. I'm having a hard time converting the wife to linux.<G> A buddy down in CT has a Powerbook running Yellow Dog also, only issue is the ATI video is not fully supported yet. just throwing my 2 cents in..

Suse Linux: Internet access

by philrmcss＠netscape.net

I recently installed Suse Linux on my Pentium III, 600 mHz computer that had Windows XP installed previously. Linux seems to work OK, except that I can't access my cable modem or dial-up modem from it. If I want to go to the internet, I have to go via windows. I got this machine from my son-in-law, and it has never printed in either windows or Linux. I have "properly" installed my deskjet 932 printer, it looks to be installed ok, but when I try to print, the printer never gets the data that the computer supposedly sends to it. Any help I can get from you folks would be greatly appreciated.

Date: Mon, 30 Dec 2002 08:04 From: "Wesley T Allen" <wallen(a)charter.net> My question is, what's known to work with Linux. Are Toshiba's friendly? I'm not touching a compaq with a 10 foot pole, and does anyone have an HP laptop that is fully functional with linux? What about the latest Dells? Or even, gasp GATEWAY???? I have a Dell Inspiron 8000 that works perfectly under Linux. I can suspend and resume it just fine, which impresses a lot of folks since they can't even do that under Windows. The 8200 is the current model; you can find 8000's and 8100's for reasonable money on eBay. It's a big, clunky-looking machine, but the internals are well done, it's very fast, and it has a very nice screen (1400x1050 or 1600x1200; none of this silly 1024x768 on a 15" screen). It can also take two batteries. I'd actually go for an 8000 rather than an 8200 if you want long battery life; the slower processors (mine is 700 MHz) make for much longer battery life. I get 5 hours from a 2700 and 3800 mAH battery; you can buy 4400 mAH batteries now, which should give about 7 hours of battery life. There are lots of other configuration options; you can get a combo DVD/CDRW drive, or two optical drives, if you like. You don't need a docking station, as it has all of the connections on the back panel. -- Robert Krawitz <rlk(a)alum.mit.edu> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf(a)uunet.uu.net Project lead for Gimp Print -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton

I'm a big fan of Dells and have run Linux on a few Inspiron and Latitude models (my current laptop is an Inspiron 8000). Every piece of hardware in it was supported out of the box by Mandrake: ATi video card, Maestro3 sound, EEPro100 onboard ethernet, DVD drive, and winmodem, which is of the Lucent variety, though I never bothered to set it up as I don't have any dial-up accounts. They're a bit more pricey than what you can find in a clearance at a store, but they're very customizable for a laptop (on Dell's web site), and that made it worth it to me. My $0.02. Brian J.

encyclopedia

by doug waud

Hi all I wonder whether I have found a gap in availability of applications for Linux :-( Specifically, I have been looking for a CD encyclopedia which will run on a Linux box (in particular a couple I set up for my two grandkids). Wine does not seem to provide a work-around both because it does not seem to be happy with any CD encyclopedia and because it would require buying Win* to get the CD stuff installed (and neither computer is worth as much as Win* would cost). I tried searching for Linux + Encyclopedia but that just gives me encyclopedias about Linux. A search for CD + Encyclopedia gave a reasonable list but none runs under Linux (as you might expect, all run under Wintel and a few on Macs). Does anyone know of a general CD encyclopedia that one can use with Linux? doug PS The grandkids take to the linux boxes quite naturally. I showed the older one how to type "lpr -Plp3 filename" to print a file. He later reported that he tried it on his brother's box but, since it was a second computer and Q comes after P and 4 comes after 3 he used -Plp4 (obvious isn't it:-) ) and it worked! :-)

RE: Linux on a PPC chip

by Sands Fish

Thanx everyone for the advice on Linux for the PPC. I ended up going with Debian, and, guided by the advice of the installation docs that come with their dist. for PPC, I had a very successful (lacking sound, but i was told to expect that, besides it's a server) installation on the G4 Mac. Now, the only other tweak I have a burning desire to make to this box is to configure the kernel to use SMP for the dual 500Mhz processors. From what I've heard, it should only be using the first one right now, and that I have to rebuild the kernel with SMP support. Sound right? I would appreciate any tips or help on getting there, such as: -> how -> where to check to -know- that it's using one or both -> any other useful kernel info anything would be great really. thanx! - Sands <x>< __________________________________________________ Do you Yahoo!?

Re: [Wlug] Color matching scanned photos vs. printed output

by Sands Fish

Andy, I do quite a bit of photo work, using Photoshop on the Windows side of things for my art. I've found that each scanner has it's own constant way of skewing the image scanned. For example, on almost every image I scan on my HP 4100C, I first go and drop the Brightness by -10, and up the Contrast by +20 - +25. Since the Gimp is so closely aligned with Photoshop, I'm sure it is not hard to adjust these two characteristics of the image. Play with these to start with. I've seen drastic color improvements and dust/scratch removal just by up-ing the contrast. Maybe if you play with it across a few different images, you can find a few constant adjustments that can be made to each image, before you start getting picky and tweaking other things like Color Balance and such. Good luck! - Sands <x>< --- Andy Stewart <andystewart(a)attbi.com> wrote: > > Hi Everybody, > > I've been playing with my new toy, an Epson 1660 > Photo scanner, which works > very nicely with Linux. > > I have noticed that photos that I scan in and then > print don't look the same > as the original.

Toshiba Laptop?

by Wesley Allen

Hi gang, What's your collective opinion of Toshiba laptops? Circuit City has got a decent machine (Satellite 1415-s173) for $999 and they actually let me boot Knoppix on it to check out hardware support (everything worked). The only thing I'm wondering about is the battery. MY HP laptop doesn't let Linux read the battery info with either apm or acpi, and I think this is a function of an incredibly bad bios implementation. The demo models at Circuit City didn't have batteries, so I had no way of checking this bug out on that brand. Does anyone have experience with a Toshiba laptop that has an acpi bios? Can you relate your experience to me? Wes
