Report Generators
by Chris Green 04 Nov '04

04 Nov '04

Are there any Report Generator programs available for Linux? I mean a program like the report generator in Paradox or Access, a program that allows data to be selected using a query and then fields can be placed as required on a form. I've found a couple on freshmeat.net, Agata and Lightbulb, but neither is what I'm after really. Agata seems quite limited and Lightbulb costs money. Has anyone used Agata, it may not be as limited as it looks at first. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

For anyone who uses procmail to sort incoming mail
by Chris Green 03 Nov '04

03 Nov '04

This is (probably) only of interest to anyone who uses procmail to sort their incoming mail into different mailboxes. Many of the mailing lists I subscribe to (including alug) insert the mailing list's name into the subject line. I got fed up with this as it wastes useful space that would be better used to show me the subject. I very often (used to) lose the end of the subject off the RHS of my screen. I already know what list the mail is from because procmail has put it pinto the appropriate list mailbox. So I played around with my .procmailrc file, read the manual pages a few times and came up with the following recipe which removes the list name from the subject (as well as storing the mail in the appropriate mailbox, as before) :- :0 fh * ^TOalug | sed 's/\[ALUG\]//' :0 A: alug -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

Migrating an Access application to Linux
by Chris Green 03 Nov '04

How easy is it nowadays to migrate an Access application to Linux? I'm getting rather fed-up with trying to maintain an Access 97 application on Windows 2000 and migrating to Linux might be the answer. -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice, that which can be explained by incompetence."

Wierd problem with G++
by Stuart Bailey 01 Nov '04

01 Nov '04

Hi, I'm trying to investigate a weird mathematical problem I've come across using G++. I only have G++ on SuSE 9.1, and so I'm unable to test the code on other systems, kernels etc. I would be grateful if someone could compile and run this code and let me have the results: #include <iostream> #include <math.h> int main() { float l = 45.4567; float d = floorf(l); float m = floorf((l - d) * 60.); float s = (((l - d) * 60.) - m) * 60.; std::cout << "l = " << l << std::endl; std::cout << "d = " << d << std::endl; std::cout << "l-d = " << l - d << std::endl; std::cout << "(l-d) * 60.0 = " << (l - d) * 60. << std::endl; std::cout << "m = " << m << std::endl; std::cout << "s = " << s << std::endl; float r = (s / 3600.) + (m / 60.) + d; std::cout << "reconstructed= " << r << std::endl; return 0; } Basically, I getting an odd value printed for l - d (it comes out as 0.456699 and not 0.4567 as expected).

Best thing is the router runs Linux which you can modify. I'm using WiFi-Box from: https://sourceforge.net/projects/wifi-box/ It adds quite a few features to the basic firmware including: Better firewall with more port mapping Built-in VPN server Able to adjust output power I noticed that LinkSys have just released the WRT54GS which claims to run about 38% faster than standard 54G.

Pro-Linux report sexed down by government
by Nick Daniels 29 Oct '04

29 Oct '04

Hope this is not to much off topic but it seems relevant: The Office of Government Commerce's report into the viability of using open-source software in the public sector was toned down in its praise of Linux security before release, silicon.com has discovered. A copy of the report, seen by silicon.com with amendments still visible, shows changes were made to the government's stance on the particular advantages of Linux versus proprietary software when it comes to security. The Office of Government Commerce (OGC) is the Treasury office charged with improving public sector procurement and project management in the UK. The pre-release version of the report read: "Linux would appear to offer numerous strengths in terms of security." In the final version this became: "There is no definitive answer on the relative security merits of open or closed-source software." The pre-release version also described the visibility of Linux code as a boon to its security, saying: "The structure of the Linux operating system is regarded as inherently more secure than that of Microsoft Windows... The open-source code can be viewed in its entirety and in the event of a problem the worldwide Linux community can act to resolve any issue with urgency." The final version, however, is more muted. "While some argue that many eyes lead to fewer security flaws, others argue that those wishing to exploit, or tamper with, open-source code have an easier time than with closed source code," it reads. http://management.silicon.com/government/0,39024677,39125400,00.htm Regards Nick

wireless routers
by Stan Fraser 28 Oct '04

28 Oct '04

Would like to share my internet connection at home between 1. Linux PC, 2. WinXP Pro PC 3. Laptop WinXP Home (but probably not for much longer). I was thinking of getting a Wireless router so I can use my laptop in the living room. Which router would anyone suggest, price range up to say £80. Also is it possible to get an old ATI All in Wonder card to show the TV? I'm using Suse 9.1 or would I be better swapping the card into the window box and the card from the window box into the Linux box? Thanks in advance for all the help

bye bye boot sector
by BenEBoy 27 Oct '04

27 Oct '04

I turned my computer on today but it stopped whilst trying to load lilo (black screen with 'LI' at the top left. It usually says 'LILO 2.whatever). After discovering the recovery disk section of the debian install CD I managed to get everything working again, but was wondering if someone might be able to suggest why it happened (and what I should do now)? I'm running a reasonably up to date sarge (apt-get upgraded last week) and haven't booted into windows for ages so I don't think it can be anything to do with that). The harddrive is about 8 months old and it isn't making any funny noises). Any suggestions please? cheers, BenE

Hard disk error
by Richard Lewis 26 Oct '04

26 Oct '04

Hello ALUG, I've just added a GB of RAM to my server. The BIOS found it alright but something strange happened when I booted up (its Debian sarge): it took about 2 or 3 minutes to start the syslogd (no disk activity or anything). Then once it had booted things got even worse! $ free -m indicates that the new RAM is working but it seems that hdb2 (which is my /var mount point) will not mount! In my /etc/fstab I have /dev/hda2 none swap sw 0 0 /dev/hda1 / ext3 defaults,errors=remount-re 0 1 /deb/hdb1 /home ext3 defaults 0 2 /deb/hdb2 /var ext3 defaults 0 2 and when I issue # mount /dev/hdb2 I get: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error } hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=39067264, sector=39067264 end_request: I/O error, dev hdb, sector 39067264 JBD: IO error reading journal superblock EXT3-fs: error loading journal. mount: wring fs type, bad option, bad superblock on /dev/hdb2, or too many mounted file systems and I can't seem to be able to do anything about because the machine hasn't connecting to the network (maybe it needs something from /var...) so I can't install hdparm. (It can't do anything which requires stuff from /var like run its web server, database server, apt, dhcp-client, ...) Any ideas whats wrong with it?

DSL anyone?
by Ricky Bruce 21 Oct '04

21 Oct '04

I know this topic comes up every few months but what dsl providers would you lot recommend. Id like to find a nice balance between cost (£25 or so a month) freebies, (a router would be a lovely although somewhat unrealistic target) and reasonable speeds. Also i might be moving from Yarmouth to N'arch in a couple of months so the ability to switch to a new property without incurring any penalties or charges would be great. And of course tech support who understood that Linux isnt some kind of Windows program but an OS in its own right. Or even tech support that understood what an OS was :) Cheers in anticipation Rick ps are all ALUGS list messages logged somewhere? LUGs i have been a part of in the past have kept a searchable archive of messages, which has been very useful in looking up past messages for info. _________________________________________________________________ Express yourself with cool new emoticons http://www.msn.co.uk/specials/myemo
