I have an XO laptop and might even go to my very first WLUG meeting (after having been on the mailing list for a couple of years.) I would also like to see how the mesh networking looks in action. Howard White Hudson

Reminder: Next Meeting: Thursday, Jan 17, 7:00 PM

by Andy Stewart

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, The topic of this upcoming meeting will be the XO laptop from the One Laptop per Child project. I'll lead the discussion with a demonstration of the hardware and software features of the laptop. If you have an XO laptop, please bring it, as I haven't yet had a chance to try out the mesh networking, and it would be fun to try in a live demo. Remember: Thursday, Jan 17th, 2008, 7:00 PM on the WPI campus in Worcester, MA USA, in the Access Grid room on the ground floor of Morgan Hall (ok, its the wedge between Morgan and Daniels). Afterwards, we'll head out of pizza at a restaurant chosen by the group.

Silence gives consent, but I learned soon after puberty that enthusistic acceptence gives a better time for all. So, I would like to break the silence on this to say: yes and his heart was going like mad and yes I said yes I will Yes. -- James Joyce, Ulysses I would consider it worthwhile to go to WPI Thusday just to see an OLPC computer.

I don't know what desktop/window manager you're using (or which Fedora includes, actually), but you have tried a more lightweight alternative? Xfce is one I hear recommended regularly, it's pretty slick. I still won't give up Window Maker no matter how many iterations of hardware I go through. ;) Brian J. Conway

Firefox + yum update is generally sufficient to bog the system. I'll try disabling some more services. Just shocks me that even though I use the system the same way, the performance is that much worse. Maybe the memory improvements with firefox 3 will help low memory systems when it comes out.

You might try to check out what's running on your system, and prune out extra daemons and the like that you don't need. Use the chkconfig and ntsysv commands to manage what services are started up. Also, you may want to try disabling the SELinux security extensions. Edit /etc/sysconfig/selinux , make sure the SELINUX variable is set to disabled, reboot, and see if that helps. -- Frank Sweetser fs at wpi.edu | For every problem, there is a solution that WPI Senior Network Engineer | is simple, elegant, and wrong. - HL Mencken GPG fingerprint = 6174 1257 129E 0D21 D8D4 E8A3 8E39 29E3 E2E8 8CEC

Fedora Disapointment

by dulsi＠identicalsoftware.com

I understand that my laptop is old. Every time I've upgraded Red Hat/Fedora, I've liked the new system until Fedora 8. I didn't always upgrade. I skipped Fedora 7 since the live CD didn't boot on my laptop but Fedora 6 ran great. Fedora 8 is a dog with my small amount of memory (256M). I'm thinking I'll buy more memory but it disappoints me that Fedora runs poorly with 256M. (I would buy a new laptop but I'm just not impressed with the current offerings.)
