AVI & WMV from Linux don't play on Windows
by Ted.Harding＠manchester.ac.uk 11 Jan '10

11 Jan '10

Hi Folks, I'd be most grateful for help with the foloowing puzzle. Background: I VHS-taped an item from yesterday evening's BBC1 "Look East", since it is of interest to people I know. I then copied this onto a "scratch" DVD, to have it readable on my Debian laptop (OK, I know it can probably be done with a cable, but I'm not up to that). I wanted to put it up on my Zen web-site so that others can view it from there (and they will mostly be using WIndows). So I first created an AVI file usingmencoder as follows (following an example in 'man mplayer'): mencoder dvd://1 \ -o denvermilllookeast2010.01.05.avi \ -oac copy \ -ovc lavc \ -lavcopts vcodec=mpeg4 The resulting .avi file plays fine using totem. I then ftp'd it to my website, and tried playing it from there using IE on Windows Vista. It failed, saying a codec was missing. However, the file on the website still plays fine on Debian with totem. So I then created a WMV file using "wmv2" format with: mencoder dvd://1 \ -o Denver.wmv \ -oac copy \ -ovc lavc \ -lavcopts vcodec=wmv2 Then I uploaded this one as well. Once again, this played fine in totem both from the file on the Debian laptop and from the copy on the web-site. This time, when I try IE from Vista on the web-site copy, I get the video OK, but no sound. So I'm wondering what the problem is, and how to solve it! In the past, I've had no problems with playing AVI files created by my digital camera using IE (video and sound both OK), though I haven't tried WMV before. So presumably there's some mysterious mismatch between the AVI created by mencoder as above, and AVI as Windows MediaPlayer expects to see it; ditto with WMV. The files in question can be found at http://www.zen89632.zen.co.uk/DenverMill AVI: denvermilllookeast2010.01.05.avi WMV: Denver.wmv and an example of a working AVI (both in totem and IE) at http://www.zen89632.zen.co.uk/Earith/Earith_Crab_2009.10.25.avi As well as the video, there is background noise from the water falling over the sluice, and from passing traffic, which comes through quite clearly both in totem and in IE. For anyone interested: this is probably a Mitten Crab which has found its way some 30 miles upstream from the sea, spotted by me when I was strolling over the bridge above the sluice-gate on the Old Bedford River at Earith, in the shallow water above the concrete sill below the sluice-gate. A still photo is at http://www.zen89632.zen.co.uk/Earith/Earith_Crab_2009.10.25cropped.jpg The location of the photo is marked "A" on: http://maps.google.com/maps?f=d&source=s_d&saddr=52.353953,0.038109& daddr=&hl=en&geocode=&mra=mi&mrsp=0&sz=15&sll=52.353901,0.038023& sspn=0.011586,0.034719&ie=UTF8&z=15 [equivalent: http://tinyurl.com/yb57epr ] Any comments on the problem would be most welcome!

Wanted, sort of Journal/Blog/Calendar/ToDo all in one, probably web based
by Chris G 10 Jan '10

10 Jan '10

Yes, I know that's a bit of a broad requirement! :-) I'm after an application of some sort that will help me keep track of what I suppose is a project (buying a boat in France). I'm open to any sort of idea really as, at the moment, I'm a bit lost as to how to do it. Straightforward calendar applications don't quite cut it as I want it to be a bit more 'textful' than that, I also want easy ways to link to web pages and other information. I might be persuaded that something like Sunbird/Lightning or evolution is the way to go though. Can one put links into sunbird entries? A blog *might* do what I want but I need easy ways to search and/or browse through entries by date and a way to remind myself to do things. I don't think blogs usually allow one to create future entries and or planning sections do they? I suppose a project planning utility might be what I'm after but they often seem a bit too much oriented towards large multi-person projects. I will go and do some looking on this front though as it isn't a way I've thought of going before. -- Chris Green

Error writing to /sys
by Richard Lewis 09 Jan '10

09 Jan '10

Hi ALUG, I'm just trying to replace acerfand <http://www.electronpusher.org/~rachel/acerfand> with acerhdf <http://www.piie.net/index.php?section=acerhdf> on my Acer Aspire One. The module comes with my kernel (Debian 2.6.31-1-686), is loaded, and reports the current temperature correctly. However, I can't enable the automatic fan control because, when I try and write "enabled" to /sys/class/thermal/thermal_zone0/mode it says "Permission denied": $ sudo echo "enabled" -n >/sys/class/thermal/thermal_zone0/mode bash: /sys/class/thermal/thermal_zone0/mode: Permission denied Or, # echo "enabled" -n > /sys/class/thermal/thermal_zone0/mode bash: echo: write error: Invalid argument I even tried switching to runlevel 1 and I still get the "Invalid argument" error. Any ideas why I can't write to this file? Or how to make it work?

Weird rendering of website!
by Ted.Harding＠manchester.ac.uk 09 Jan '10

09 Jan '10

Hi Folks, Still following up one of my current side-interests, I visited the website http://www.denvermill.co.uk using Iceweasel on Debian Etch. Hopeless rendering of text (massive vertical expansion), much of the page simply missing, and hardly any of the links apparently active and none of them working. On the other hand, if I view it in Windows Internet Explorer then it all seems to work perfectly. What might be the explanation for this difference? Best wishes, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 08-Jan-10 Time: 13:28:07 ------------------------------ XFMail ------------------------------

UPS + LAN Switches that don't blow up after a power cut!
by stevey.eu 07 Jan '10

07 Jan '10

Having only just got back on after 24hours, I have no end of issues, so am thinking a UPS is in order. That and my LAN switch no longer works. Any suggestions for suitable replacements would be handy right now. Cheers, Steve

Which way of using rsync will be faster?
by Chris G 07 Jan '10

07 Jan '10

I'm using rsync to copy some files across my LAN. There are various ways I can do this and I'd like to know which is likely to be fastest. The (most obvious) ways I can see of doing it are:- 1 - Run rxvt in conventional fashion across the network to the remote system, e.g. with syntax like:- rxvt -a /thisDir/ thatSystem:/thatDir/ 2 - Use the (already mounted) NFS mount of the remote system and, from rxvt's point of view copy locally:- rxvt -a /thisDir/ /mnt/thatDir/ 3 - sshfs? Doesn't really seem a very sensible candidate. My *guess* is that probably option 1 is best but I'm not really sure. The object is more to minimise system load (and network load) than to get the absolute best speed. The copies (backups) will likely run when I'm using the system so I want them not to overload things too much. -- Chris Green

Cannot empty trash
by Mark Rogers 05 Jan '10

05 Jan '10

On my Ubuntu 9.10 desktop, I have the trash applet in my Gnome taskbar and it says I have 2 items in trash if I hover my mouse over it. If I open the trash, there's nothing there. If I select the "empty deleted items folder" option it has no effect. There is nothing in ~/.local/share/Trash/(files|info|expunged) I'm guessing that something has been deleted on an external or other mounted drive that has since been removed without emptying the trash properly, but I can't see how to clear the trash so that it appears to be empty. Googling just sends me to endless pointers to ~/.local/share/Trash and/or the trash-cli package, neither of which have helped. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Online command line info pages?
by Anthony Anson 04 Jan '10

04 Jan '10

I'd be grateful if someone could point me at a page/pages which give the scripts for commands I can type into a 'terminal', so I can make things happen in this awful Kenvironment. Too hurriedly, I bought 'Command Line & Shell Scripting' - at huge expense, only to disover that a) because what the author really meant by the title was 'Shell Scripting in a ommand Line Environment', b) I can't haggle with Borders about exchanging it, -- Tony Anson www.girolle.co.uk/
