Finding directories whose contents have changed since yesterday
by Mark Rogers 05 Mar '09

05 Mar '09

What I want to do is write a script to backup some databases, but only if they've changed. I figured that the easiest way to get a list of databases that exist, as well as which have changed, is to look in /var/lib/mysql for directories with recently changed files. I know that find /var/lib/mysql -type d -mtime 1 .. will find directories that have changed inside 24 hours, but it does not pick up directories whose contents have changed. Any suggestions? (The next problem is that the user I want to run the script as does not have access to the /var/lib/mysql directory at the moment so a more elegant solution would be nice.) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

High CPU usage for sudo?
by Mark Rogers 05 Mar '09

05 Mar '09

According to top on my desktop: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 18387 root 20 0 2876 976 952 R 83.3 0.1 3291:33 sudo 31304 mark 20 0 405m 254m 30m S 8.9 16.8 298:14.33 firefox 5964 root 20 0 190m 80m 13m S 3.3 5.3 142:12.89 Xorg 31994 mark 20 0 62364 24m 10m R 1.3 1.6 1:03.30 gnome-terminal 6196 mark 20 0 46292 10m 8256 S 0.7 0.7 3:28.18 gnome-settings- 6303 mark 20 0 90664 50m 7160 S 0.7 3.3 103:36.48 multiload-apple 11225 mark 20 0 111m 26m 17m S 0.7 1.7 13:11.20 deluge 31092 mark 20 0 2416 1172 876 R 0.7 0.1 0:00.08 top 6243 mark 20 0 21392 5032 4328 S 0.3 0.3 5:03.73 gnome-screensav So that's 83% for sudo... I just sat watching it for a while (I only fired up top as the machine was running slow) so although the above is a snapshot it's indicative of a pattern at the moment.

Flash Player 9 test?
by Ted.Harding＠manchester.ac.uk 04 Mar '09

04 Mar '09

Hi Folks, To compare notes -- would anyone like to try playing the video linked to from the news article at http://www.cambridge-news.co.uk/cn%5Fnews%5Fcambridge/ DisplayArticle.asp?ID=396400 When I clock on the "play" arrow, it crashes my Iceweasel (2.0.0.19 on Debian Etch). If I right-click on the image, I get a pop-up which makes it look as though the video is intended for Flash Player 9. I have Flash Player 9 installed, and have often used it successfully on other sites. With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 04-Mar-09 Time: 16:56:57 ------------------------------ XFMail ------------------------------

Linux Certification...
by James Elsey 04 Mar '09

04 Mar '09

Hi Guys, I’m thinking about taking some kind of Linux certification, and I’m wondering if any of you have done this and what views/advice can you give. I’m interested in taking the Ubuntu certification, primarily because that’s the distro I’m most familiar with, yet I’d still class myself as a “beginner” user ( I can install software, work my around the terminal etc etc) I’ve read that you need to take LPI 101, 102, and 199 for this, but I’ve also read that the UCP is somewhat of a gimmick compared to the Red Hat certifications Are these qualifications recognised well, i.e. did they help you with new jobs in the past? I’d love to hear any advice you can give regarding Linux certifications. I don’t get to use Linux as much as I would like to, so I’m hoping these will provide me with some incentive to “knuckle down” and get on with it :) James Elsey Junior Developer Serengeti Systems Limited Serengeti House Kersey Maltings Kersey, Ipswich IP7 6DP Company registered in England & Wales Registration No: 3578108 T: 01473 825 002 D: 01473 825 013 E: HYPERLINK "mailto:chris.roberts@serengeti-systems.com"james.elsey(a)serengeti-systems.com URL: HYPERLINK "http://www.serengeti-systems.com/"www.serengeti-systems.com No virus found in this outgoing message.

Alug 10th anniversary!
by Adam Bower 01 Mar '09

01 Mar '09

Hi all, May 2nd this year marks the 10th year of alug! (well, of the kit meetings anyhow, it did exist as a mailing list before that for a while). Anyhow, in recognition of this who wants to have a kit meet? I'd like to arrange something for the weekend of the 2nd/3rd May and the precise day depending on who is available and wants to come along. As yet we have no planned venue either! Anyhow, who is out there who wants to come along? Will a kit meet format be suitable? Is there something else we should do? Should we have some vintage Linux distros? Thanks Adam -- jabberid = quinophex(a)jabber.earth.li

Watch this space - just got Lenny and There-Will-Be-Questions[TM]
by Anthony Anson 01 Mar '09

01 Mar '09

Just received a 5 DVD set of Lenny, and am building a box to keep him in. In the meantime, I'm going to put it all on a HDD on this box (HD0 in a tray) ATM the HDD (40 GB) is hosting a cut-down version of Sarge - which I've never got on with, preferring to run Knoppix from DVD. However, that's by-the-bye, I'll be able to find old friends (fiends?) like Gnome on the CDs - the entire contents of which I intend decanting into magnetospace. Anyone used VirtualBox for Windows-based programs, especially anything written in VB-net? -- Tony http://www.users.zetnet.co.uk/hi-fi/

Network Browsing via Homeplug
by steveydoteu 01 Mar '09

01 Mar '09

When browsing the home network, specifically on Windows as far as I can recall, there seemingly is no other device on the network in the entire house, which is of course not the case at all. Obviously this causes issues when trying to browse shared folders and so forth. Internet is connected to the system from a LAN switch which in turn is connected to a homeplug device, that obviously, recieves the internet from the router upstairs. I am wondering if there is a simple solution that I am missing here!

puzzling result from who command
by Peter Alcibiades 27 Feb '09

27 Feb '09

I needed to run the who command, and was surprised to discover that my user was logged in three times. It was something like the following: al@athene:~$ who al pts/1 2009-02-27 07:19 (:0.0) al pts/0 2009-02-27 07:19 (:0.0) al pts/3 2009-02-27 07:19 (:0.0) Though the dates on one of the entries was different. Like an idiot I failed to copy the thing when it was showing. I then shutdown and rebooted, and it now comes up with one login as expected. Why would this happen? Peter
