Date Output Setting in Postgres
by Rajen M. Parekh 18 Feb '05

18 Feb '05

Hi, I am having problem setting the "Date" output settings. I am using Postgres 7.4.3. I have changed the datestyle setting in "postgresql.conf" as, datestyle = 'SQL, DMY' But still when I do a show all, I get DateStyle ISO, DMY Why is it stuck with "ISO", instead of "SQL". The reason I want "SQL" is that I want the date output format as dd/mm/yyyy instead of yyyy/mm/dd when I browse the records. Another problem was that I could not set the datestyle with the SET command. So, I modified the postgresql.conf file. But still the problem is only partially solved as the datestyle still remains "ISO", instead of "SQL". I am using phpPgAdmin as frontend. Thanks, Rajen.

re: attempting dual boot. is anything to be kept in mind

From: linman ferns <linmainwala(a)yahoo.com> To: linuxers(a)mm.ilug-bom.org.in Date: Thu, 10 Feb 2005 08:21:38 -0800 (PST) Subject: [ILUG-BOM] attempting dual boot. is anything to be kept in mind hi friends, i am attempting a dual boot. i have a 80 gb hard drive. 45 gb is formated for win 98 and the rest is kept unformated. is there anything that i should be aware of. people who have tried this ealier kindly tell me what i should take care off. thanks a lot hi, if possible try to backup your data. also if trying to dual boot make sure you have all the necessary documentation regarding creating a dual boot. i personally had win 98 and made it to dual boot with yoper linux. however when i did it the first time, i could not start yoper linux. then after searching on the yoper linux forums, i found that after installation i had to execute a command to configure lilo so that i had the dual boot during restarting of the computer. also most linux distributions have a utility at the start that checks if the cd is good or bad. use that because if the cd is bad then the installation will stop midway and corrupt your disk. just some friendly advice. regards, kevin

Looks like a device scan output. Couldn't make anything out. Saved this from RHL. Looks real screwed up in Notepad... must be diff in newline char usage. Home Setup: 2m/cs -crossover cable. RHL on PentII dual boot with win98. Would RHL auto assign IP/s like Win. the link works with Win98<>WinXP on M/c2 O_this_T Could someone let me know what is the equivalent of a Windows 'dir /s Image*.*' in linux.

KDM theme for KDE-3.4
by Sameer Niphadkar 17 Feb '05

17 Feb '05

Hi, I just downloaded and installed KDE-3.4b1 on my SUSE 9.0 box. Now there is this really nice KDM theme for v3.4 which I wanted to install as my default theme (from www.kde-look.org ). I downloaded the theme and when I configured the kdmrc file it still did not work...I did the following changes to the file $KDEDIR/share/config/kdm/kdmrc (where Tux-Mania is the new theme) Theme=/opt/kde3.4/share/apps/kdm/themes/Tux-Mania UseTheme=true But still when I rebooted it brought me back to the same plain vanilla login screen. I even managed to look in the kdm log files and found the following errors ******************************************************************* (WW) I810(0): Failed to set up write-combining range (0xf0000000,0x8000000) Symbol drmCtlUninstHandler from module /usr/X11R6/lib/modules/drivers/i810_drv.o is unresolved!

2OS-1Machine-NewThread
by Rony Bill 17 Feb '05

17 Feb '05

Dear Friends, The discussions on the use of 2 OSs in one machine and the question by Saswata about its uses got me thinking and I have visualised a concept. What is being done is simply multi-tasking. Any OS is a set of tasks that the cpu is carrying out and 2 OSs means the resources are shared by two sets of tasks (OSs). This jugglery is carried out by the RAM which loads two seperate OSs in its space and uses the necessary swap space on the HDD for extra resources. The Concept:- Generally in an office setup, a normal Pentium 400 MHz system with 256 MB RAM, 100 MHz bus and a 10 GB HDD is sufficient for doing letter writing, data entry, email, surfing, printing etc. Suppose an office needs to use 8 computers for 8 operators, with different OSes for different software or even same OSes, 8 computer systems will need to be purchased. 8 computer systems will have to be taken for AMCs ( Yeah ! ). Instead of that if all the hardware requirements are bundled up into one system then that would bring down costs. The CPU will be 400 MHz X 8 = 3.2 GHz. The RAM 256 MB X 8 = 2 GB. The BUS speed 100 MHz X 8 = 800 MHZ. The HDD 10 GB X 8 = 80 GB Thats what the latest systems can give you. The motherboard will have to be special type that accomodates atleast 8 PCI slots that will contain low cost multifunction cards that have VGA, PS2 Keyboard and PS2 Mouse outputs and for more elaborate ( $$$ ) ones, a LAN and 56 Kbps modem with it too. This provides capacity to run 8 Monitors, Keyboards and Mice for 8 operators. The BIOS will be more advanced with a facility to create 8 RAM partitions with each partition getting a quota of max 400 MHz of CPU speed and 100 MHz. of BUS speed. This prevents viruses or runaway programs from one OS upsetting the whole system. When installing any OS, it will ask which RAM partition is to be utilised, just as we select HDD partitions. In this way we can get upto 8 different (or even same) OSes running simultaneously in one system. It is an ideal option where a heterogeneous envirinment is necessary. This will not only save initial costs tremendously but it will also save on AMCs ( Ouch! ) as the total number of machines is only one instead of 8. Since the hardware resources are common, a LAN will not be required to make the 8 computers see each other within the same system. If we can have systems with 2 CPUs and dual busses, then upto 16 computers can be created from one system with the 400 MHz combination. Imagine the savings for companies that use 50 or 100 computers or more. Even the space required will reduce. With wireless technologies becoming cheaper, the monitors, mice and keyboards can be wireless to avoid clutter and increase distance from the main system. Regards, Rony.
