Re: [Haifux] Legal issues regarding iwlib and wireless linux extensions
Just a thought, what make you think that syscalls are slower? If i understand correctly, syscalls are not context switches, just passing into kernel mode which you will have to do anyway.

It is possible, especially if you used a dialer script like netvision scripts etc... I.e. the routing tables have a default gateway that came from that scripts. Another possibility, if the ethernet cable is long like 15meters and the ethernet is on board, perhaps you need to change the interface to 10MB-FD. This sometimes happen with the cheap boards. Though if it worked on windows without touching anything in the drivers, than it shouldn't be a problem. In the end, we need to have some output in order to help you.

RE: [Haifux] Honey, I shrunk the club
Please do NOT flame. I am a little reluctant to offer because I know someone will say "do it yourself" but I don't have the time to do it all (maybe some). I think the problem is "selling" linux to average joe in a non-too-geeky-for-me way and making would be visitors more comfortable to get involved. A few suggestions to haifux site: 1) In order to increase haifux involvement and keep in touch with visitors and allow members to know lecturers more: Allow (not mandatory) haifux visitors to register (Register button big on top of main page) in haifux.org the registration can include: Name, handle, Picture, email, ALL(IMs),register to mailing list phone, comment on self, interests, RSA key. Links to past lectures given, list of lectures attended (self editing), link to home page, link to blog page, links to favorite linux/FOSS sites. Perhaps, rudimentary blog. 2) Provide (little hype here) web 2.0 services: Inside haifux.org allow to create presentations using WiKi methods with permission to edit from lecturer (or not). Or provide a trust ring, lecutrer know/vouch editor so its ok to edit. Provide a request page, requesting to lecture on a ready lecture. (good for when there are no lecturers available) 3) list of proposed lectures and member voting on prefered lectures. Available ready lectures will be lectured first when no date was set. Also, members can assign lectures to preffered date slots so a maximal number of members will be able to attend a desired lecture. Maybe include incentives to lecture, like if you do a lecture you get strong point to secure other lectures or get tshirts etc... 5) Main contacts/emails on main page to outside non-members who wish to promote/lecture/sponsor. 6) Move clutter like logos etc... to the bottom and put registration, main contacts, arrival, etc.. on top. 7) Provide main page pictures on meeting place and people having fun :) Increase sense of casual, fun, non technion-students-only-will-understand atmosphere.

RE: [Haifux] Honey, I shrunk the club
Yesterday was purim, and I personally wanted to come but couldn't because we had to read the megilla at that time. I guess that others couldn't too. As per lecture, I think its also subject based. It's subjective per person to evaluate if a lecture is relevant to him. I am sure that if a technical person like a linux guy feels that a lecture is important for his edjucation, he will be there. Also, raw information can be found on the internet and people won't come if they feel they can find this info on the net without any added value. For example, I liked the Ruby Rails lecture because of the examples there and personal zeal. I like the C lectures, portability programming, gnucash, stam disk, linux memory allocations,xen, probably forgot a few, because they gave first hand important experience from the "field". etc...

RE: [Haifux] 'Hibernate' on Linux
I am no expert on the subject, and i never seen it happen but: You forgot to mention what type of laptop do you have? if its a thinkpad or something that uses its technique for hibernation, you can create a dos partition that is as large as your memory (and add some 10mb just to be sure) on the first partition of the disk. i.e. so it will be c:\. the bios will try to wake from hibernation and go to hibernation to that partition using a file called hibernation.sys. There are some problems that you will need to fix using some utilities that you can find for thinkpad on the net that fixes, times, etc... better use the apm thingie in combo, or if it has support for this kind of things. * - * - * Tzahi Fadida [EMAIL PROTECTED] Technion Email: [EMAIL PROTECTED] * - * - * - * - * - * - * - * - * - * WARNING TO SPAMMERS: see at http://members.lycos.co.uk/my2nis/spamwarning.html > -Original Message- > From: Haifux - Haifa Linux Club [mailto:[EMAIL PROTECTED] Behalf Of Haim Cohen > Sent: Tuesday, July 01, 2003 11:35 AM > To: Nadav Har'El > Cc: Haifa Linux Club Mailing list (E-mail) > Subject: RE: [Haifux] 'Hibernate' on Linux > > > I did so, but when turning on the computer, it did not wake up from its > hibernation... > By 'hibernate' I mean to save all the memory contents to disk, so the computer seems > like > turned off. > > Thanks, anyway. > > > > > @/' > Haim Cohen > Software Engineer > Analog Devices > Israel > (972) - 9 - 9715 406 > > > -Original Message- > > From: Nadav Har'El [mailto:[EMAIL PROTECTED] > > Sent: Tuesday, July 01, 2003 10:11 > > To: Haim Cohen > > Cc: Haifa Linux Club Mailing list (E-mail) > > Subject: Re: [Haifux] 'Hibernate' on Linux > > > > > > On Tue, Jul 01, 2003, Haim Cohen wrote about "[Haifux] > > 'Hibernate' on Linux": > > > Hi, > > > > > > I have RH-9. > > > Does some one know how can I hibernate my computer ? > > > When I had windows-XP, I could hibernate, so I know for > > sure the hardware supports it. > > > > Try running "apm -S" (as root).

RE: [Haifux] [MSG from Mark Silberstein] Sandboxing in linux
I am probably of the mark because you probably know that, but chroot is a sandbox of a shell. i am not a linux programmer, but i think there are libraries for this chroot thing, so maybe it will suit your needs. also, maybe there are already products that uses these libraries for these ends. User Mode Linux, seems exsesive for just one application, and will definetly will lower performance by a few precent. Definetly not, Vmware or plex thingie, since performance will go down the drain on these babies. Only if this is an application that needs a dedicated server, then i won't rule out using the emulators, otherwise chroot looks like the choice. * - * - * Tzahi Fadida [EMAIL PROTECTED] Technion Email: [EMAIL PROTECTED] * - * - * - * - * - * - * - * - * - * WARNING TO SPAMMERS: see at http://members.lycos.co.uk/my2nis/spamwarning.html > -Original Message- > From: Haifux - Haifa Linux Club [mailto:[EMAIL PROTECTED] Behalf Of Orr Dunkelman > Sent: Tuesday, June 24, 2003 4:53 PM > To: Haifa Linux Club > Cc: Mark Silberstein > Subject: [Haifux] [MSG from Mark Silberstein] Sandboxing in linux > > > Hello all, > I am looking for the solution to run application in sandbox.
