Bbattery charging "mystery"
by Ted.Harding＠manchester.ac.uk 10 Mar '09

10 Mar '09

Hi Folks, Yesterday I observed something which surprised me (running Debian Etch in VirtualBox in Win XP on an Advent 8117 laptop). WHen I sat down at the desk, I noticed the battery-charging LED flashing. When I check the battery level monitor (in both Debian and XP) it was at 20% and charging. An hour later it was fully charged. I generally leave the laptop running continuously, days on end, and its power supply is permanently connected to the mains. It's possible that something disturbed to connection for a while (perhaps most likely where the mains cable connects to the PS brick), and that something later re-established it (I do tend to swim in a pile of clutter so stuff gets pushed around), but the event prompted me to wonder the following. Might it be that, if a laptop (at any rate for some models) is kept continuously connected to the mains for days on end, then for the sake of battery health a re-charge cycle is initiated, whereby the input from the mains-connected PS brick is internally disconnected for a while, until battery-level drops to a fairly low level, and is then re-connected? It is, of course, known that it's good for battery life to submit it to a discharge/recharge cycle every so often; but I've not heard of this being built-in to laptops' power monitoring. (But then there's a lot of stuff I haven't heard of).

Optimising MySQL and/or Apache for speed
by Mark Rogers 10 Mar '09

10 Mar '09

I have a server which was originally a low spec virtual machine with 128MB RAM, but which is now running on 4-times that RAM (shortly to be doubled again) and a faster "CPU". Available bandwidth has also been doubled. With the increase I'm disappointed not to be seeing much difference in the performance of websites on the server. Many of them are heavily database dependent with lots of queries, so the real fix is to optimise the code itself, but in the short term the CPU and memory hike needs to be showing some kind of benefit. The behaviour of the server is to work fine then suddenly run like a dog for a while, then come back up. How do I go about finding what the bottleneck is? ("top" showed both before the upgrade and since that no swap is being used and CPU usage is never particularly high, with Apache sometimes hitting ~20% but mostly not showing. In case I have some kind of virus/trojan/etc lurking, advice as to what to look for there also appreciated. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

SuSE help!
by Yvonne Everett 09 Mar '09

09 Mar '09

Hi I've just had delivered an HP 2133 with SuSE installed. I have broadband connection at home which is setup with an ADSL router so I normally just have to plug in and the connection to the internet is direct. From the console session I can see the router, I can see that I have an IP address and I can even ping google.co.uk, bbc.co.uk etc. However, I cannot use Firefox, eventually I get the timeout message. Also I cannot get online updates (I've tried apt-get update from the command line) and I cant even seem to find the icon where I register for updates. Can anyone help me please as I'm new to SuSE (I have used Ubuntu previously). Thanks -- Yvonne Everett Email: ye103910(a)googlemail.com

I seem to have acquired a stack of linux related books, some of which I know are from the ALUG library (any any that aren't I'm happy to donate). Who should I return them to? and how? Keith

OpenOffice and "yrt.doc"
by Ted.Harding＠manchester.ac.uk 08 Mar '09

08 Mar '09

Hi Folks, Dunno if it's just my installation, or if it's a general thing. Whenever I open a ".doc" in OpenOffice oowriter, or even just start up oowriter without nominating a document, the first thing that comes up is a panel which says: Openoffice.org Document Recovery Recovering document: [ blank ] Status of recovered documents: Document Name Status yrt.doc Not recovered yet [Start Recovery] [Cancel] Then, if I click on [Start Recovery], this changes to Status of recovered documents: Document Name Status yrt.doc X Recovery failed [Finish] Then, when I click on [Finish], it proceeds to open the document as if there had been no problem. It doesn't seem to happen, however, with oocalc (the spreadsheet). There does not seem to be a file "yrt.doc" anywhere on my system. Perhaps it was looking for some basic system/template file which it did not find, hence the messages. But I'd like to know what's going on, if anyone knows! With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 08-Mar-09 Time: 01:10:59 ------------------------------ XFMail ------------------------------

similar to mac mini but cheaper?
by Albert Vilella 07 Mar '09

07 Mar '09

Hi, Does anybody know if there are alternatives to the Mac Mini but cheaper and with Linux installed? I've found the Eee Box and the Dell Studio Hybrid, but I still find them expensive and not available with Linux on most models. Anyone? Cheers, Albert.

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
