Scripted editing of PDF files
by Mark Rogers 14 Jul '08

14 Jul '08

Does anyone have any idea how to perform command-line PDF editing? The sort of thing I am talking about is adding text to the document maybe even editing existing text if that's possible. (The PDF will be a poster for printing, I need to change some details and return it. The quality of the PDF is therefore important and converting (say) to JPEG, adding the content, then converting back, will probably not give adequate results (unless someone knows better?) For test purposes I have tried things like: convert test.pdf test.png convert test.png test2.pdf .. and the quality difference between test.pdf and test2.pdf is noticable (colour definition has reduced, and the image has become grainy). In fact, even: convert test.pdf test2.pdf .. gives almost identical results to the via-jpeg test, which makes me think something like that is happening anyway. It may be that I can improve the above tests with convert if anyone has any suggestions? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Comparison of CPU speeds
by Ted.Harding＠manchester.ac.uk 10 Jul '08

10 Jul '08

Hi Folks, Sorry for any cross-posting which may affect any of you! I've been asked the following, but don't know the technicalities to provide an answer myself. Given that a certain simulation job (10,000 rounds) takes 6-8 hours on an Intel Pentium 4 CPU 2.59GHz machine, what might it take (i.e. what speed factor) on a machine with a) IntelR CoreT2 Duo E6400 b) IntelR CoreT2 Duo E6600 c) IntelR CoreT2 Duo E6700 (Ball-park will do). I haven't been given the GHz speeds for these other processors, but a quick Google suggests they're all around 2.6GHz, give or take a bit. The computations for the simulation are numerically intensive; also much reading to & writing from RAM. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 09-Jul-08 Time: 21:43:45 ------------------------------ XFMail ------------------------------

For me being less technical it is hardly worth trying to do the editing. After posting this message i was searching through the bits 'n' pieces that came with this machine to find an XP recovery CD set. Making the windoze HD master again and installing XP took little more than about 20 mins - all the drivers necessary being already there... thought i was going to have a hunt on 'drivers guide'. I'd always wanted to avoid dualboot but this 2HD method seems better than partitioning. While i have only a couple of apps and a scanner to run on windoze - i still find certain DVDs a pain to run on ubuntu. I'm now happily watching my Telegraph compilation of previous wimbledons which was somehow prepared for windoze as RealPlayer and others didn't work properly. james

Ubuntu 8.04 - dualboot on two hard drives
by James Freer 08 Jul '08

08 Jul '08

I've read a post on this on another forum and somehow it doesn't seem to work for me... ubuntu 8.04 seems quite clever. It finds the winblows drive and puts the necessary code at the bottom of the menu.lst file. I'd rather use dualboot with two drives as it is then easier for installing new ubuntu releases (IMHO). hard drives both standard IDE on a 2.6ghz desktop. master drive - ubuntu 8.04 slave drive - win2k (no reason other than i don't have a copy of XP... my only reason for wanting to do dualbooting is that i've got several apps and a scanner than i can't run on ubuntu) Following the beginning of the guide that worked fine - installing win2k on master and then connecting the master for ubuntu carefully switching the win2k disk to slave. I want ubuntu to load as default. I read through the forum listed menu.lst carefully taking note of what was said about needing to put the ammendments at the bottom of the file. In 8.04 at the foot of menu.lst IT IS ALREADY THERE - no editing required. It would seem that 8.04 DOES the necessary! On rebooting i selected the bottom item i.e windows and it didn't seem to load. windows message "Windows 2000 could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware" I don't think this message can be relevant to the problem as i installed win2k fine? I'd be very grateful if you put put me right! Menu.lst below 8.04 original no ammendments. thanks james # menu.lst - See: grub(, info grub, update-grub( # grub-install(, grub-floppy(, # grub-md5-crypt, /usr/share/doc/grub # and /usr/share/doc/grub-doc/. ## default num # Set the default entry to the entry number NUM.

Re: [ALUG] Help Keyboard madness!
by Peter Alcibiades 07 Jul '08

> > It could be a KDE thing. Check the file ~/.kde/share/config/kdeglobals > and look for the settings for "Log Out" and "Log Out Without > Confirmation". It's possible that one of those may be set to 'd'. Thanks a million guys! Went around this am, and this is what it was. Tried with IceWM first as suggested, and that was OK, so it pretty much had to be KDE. No idea how it can have happened, but its fixed now. When resetting the configuration so that lock becomes (Ctrl+Alt+d) in a text editor, of course, the minute you type the 'd', it drops you to a locked session without making the change! So the only way to get the d in is to do cut and paste. It is stuff like this that keeps blood flowing in the brain. Cheers Peter

Help keyboard madness!
by Peter Alcibiades 07 Jul '08

07 Jul '08

This is a truly weird one. Installation is Mandriva 2008 One with KDE. Whenever the lower case d is pressed, the system instantly logs off the user and starts a new session. What on earth can be going on? Upper case D does not do it. Changing the keyboard makes no difference. Restarting makes no difference. We have done nothing I can think of to set this (and I would not know in any case where to set it). Anyone heard of anything like this ever? I've a feeling the solution to this and other problems is going to be Debian sooner rather than later.... But I'd really like to know how to figure out what on earth could be causing it. Al

Can on specify a default sort order for applications (as opposed to ls)?
by Chris G 03 Jul '08

03 Jul '08

Is it possible to specify a default sort order for all applications to use as opposed to just ls (and/or the default file manager)? I'd like to get files shown in date order rather than alphabetic order *everywhere*, is there some way to tell the system to do this? Even a way to tell Gnome or KDE apps would be useful. -- Chris Green
