Broken clipboard
by Mark Rogers 05 Dec '07

05 Dec '07

Dunno how but I've broken my clipboard! Any time I try to paste I get: ŸŸif (empty($job_rec->data['start'])) $job['start'] = date('Y-m-d'); The PHP code is something I did copy to the clipboard (don't know about the two leading chars though), but nothing I've copied since has "taken". Using glipper I can see the clipboard history, and if I copy something that's being added to the history just fine. It's only paste that doesn't work. I have had the problem once before and a reboot fixed it, but now that I'm not using Windows I don't see why I should have to reboot every few days! The two leading chars were the same last time, I think (upper case Y with umlaut). Only clue I can think of: I use Synergy (synergys.sf.net) to allow me to use one keyboard/mouse between two PCs, and amongst the things it does it copies the clipboard between machines. This machine is the Synergy server. (The other (client) machine is Win2k.) I've killed Synergy since the problem started and the clipboard is still broken, though. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Recovering deleted files that a process still has open
by Mark Rogers 05 Dec '07

05 Dec '07

I have a vmware-server installation running a virtual machine, however I have subsequently (and accidentally) deleted the .vmx configuration file. It appears that VMWare still has the file open, so it won't (as I understand it) be lost until VMWare is closed (eg I reboot the machine). Is there anything I can do to recover the file whilst in this state? (O/S is Ubuntu 7.04 if that helps.) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

How to display result of remote PHP script within a HTML page
by sagr 05 Dec '07

05 Dec '07

Hi folks. A very dumb question from a HTML / PHP beginner... I have written a simple hit counter prog which I can access by running: http://www.suffolk-ancestor-genealogy-research.co.uk/counters/counter.php?w… I now want to integrate this into a HTML website page, so that this remote script "counter.php" is run and the result displayed on the HTML webpage each time the page is viewed. I have created a simple HTML page: http://www.suffolk-ancestor-genealogy-research.co.uk/counters/count_page.ht… which just consists of: <HTML> <BODY> <script src="http://www.suffolk-ancestor-genealogy-research.co.uk/counters/counter.php?w…"></script> </BODY> </HTML> When I go to this count_page.html webpage the hit counter is incremented but the result is not displayed on the webpage (even though it's output is visible when I run the script counter.php directly). How do I get the result from the remote script counter.php to display on my count_page.html page? sagr

Lyx - anyone use it?
by James Freer 04 Dec '07

04 Dec '07

ubuntu 7.04 I'd be grateful if someone could put me right on the following. I installed lyx through aptitude as i believe it takes more care with the dependencies. When i ran it i got the following - is this a bug? It actually seems to work OK - from what i've tried so far! I read that one is supposed to use lyx-qt in the command line but it doesn't seem to make any difference... from what i can see! thanks james j@j-desktop:~$ lyx X Error: BadDevice, invalid or uninitialized input device 167 Major opcode: 144 Minor opcode: 3 Resource id: 0x0 Failed to open device X Error: BadDevice, invalid or uninitialized input device 167 Major opcode: 144 Minor opcode: 3 Resource id: 0x0 Failed to open device Locale en_GB could not be set

regex, kate, gedit
by Peter Alcibiades 04 Dec '07

04 Dec '07

Hi, probably a silly question with an utterly obvious answer, but it would be great if someone can enlighten on it! I'm searching and replacing a text file. In gedit, if I search for \n\r I get, as expected, a match at every line end. Same with \n or \r. However, in Kate or Geany, I do not. Tearing hair out. What could be the problem? I've tried \n [\n] I've tried building up the expression in the K regex builder. I've tried selecting the line feed character and doing copy and paste. In Gedit it yields \n\r. In Geany it yields a couple of small square boxes with dots in them, which I then can't search on. Changing the coding doesn't seem to help either. At least, the ones I have tried. Is this likely to be the explanation? It displays fine however, so how do I find out which different coding to use? I would just do it in Gedit, except that as usual in the effort to make their apps unusable for anyone who wants to use them for anything, Gnome decline to support regex..... Peter

Webcam as security monitor
by Greg Thomas 03 Dec '07

03 Dec '07

Just found an old webcam at the back of a cupboard, plugged it in to my Ubuntu box, installed Camorama, and woot! it works. Which set me to wondering. Camorama can be to record a picture from the webcam every (say) 20 minutes. What I was wondering was is there is any software out there that records the picture at a set interval, but only if the webcam image changes (you'd presumably need some sort of change threshold, to cope with minor changes). Any thoughts, anyone? Greg

Time management software in Linux
by David Studholme 29 Nov '07

29 Nov '07

What do folks use to manage their 'to do' lists and track time spent on various projects? Up until now I have used scraps of paper. But I just installed Gnome Time Tracker 2.2.2. ('gnotime') from the debian repository. This appears to provide all the essential functions, but is, alas, unusable. This is because the drag and drop editing of the project hierarchy behaves unpredictably. Are there any good usable open source alternatives? Thanks, David.

It's a desktop wiki which can be used pretty effectively as a general purpose notepad, if it fits the way you work. Worth a try - to install, you just download a web page which makes it very easy to move around on memory sticks etc. Peter.

Gnome configuration
by Dan Hatton 29 Nov '07

29 Nov '07

Dear All, I decided to have a play with Gnome (usually an FVWM user.) I managed to get a nice user-friendly desktop by doing ln -s /home/username /home/username/Desktop/username and creating a .xsession file that said #!/usr/bin/tcsh /usr/bin/gnome-panel & /usr/bin/gnome-wm But when the session's finished with, hitting the "Log out" option in the system menu only seems to close the gnome-panel, not actually to end the X session. I suspect that this is because I'm starting gnome-panel the "wrong" way. Any ideas, please? -- Thanks, Dan Hatton

Multiple MySQl MySQL replication (on Debian/Ubuntu)
by Mark Rogers 27 Nov '07

27 Nov '07

Has anyone here played with database replication using MySQL on Debian/Ubuntu? What I have is a database server running a few dozen databases, of which a handful I need to replicate at the customer's premises. That is, for sake of argument, 20 databases on the server, 5 of which need individually replicating to 5 customer offices. Last time I looked at this there were two options, described below for those who care. My problem is that both require me to run multiple database instances and every time I've tried to make MySQL do that from a Debian/Ubuntu binary installation I've failed. Does anyone here have any experience in that area? (I had no joy at all from the MySQL forums last time I went through this; the Debian builds seemed of little interest to MySQL devs.) ---- Option 1. Tell MySQL to create a binary log, with logging enabled on the 5 databases. Run 5 additional database instances using the blackhole database engine, which replicate one database each from the master binary log and use it to create their own logs. Set up MySQL at each customer site to replicate from their respective blackhole database instance. [Background: MySQL can (or could?) only log to a single binary file, so this messing around is required to split the logs out; each blackhole database instance receives the data for all 5 logged databases but ignores everything except that for its own database, which it then logs. The customer's server replicates against that. Otherwise the customer's server has to pull the data for all 5 databases to ignore 4 of them, a bandwidth hog and (more importantly) security flaw. The blackhole database engine simply dumps all data to /dev/null (ie it stores nothing) but in the process maintains the logs correctly.] Option 2. Remove the 5 databases in question from the main MySQL instance, and create new 5 MySQL instances (one for each database that needs logging). Let each separately create binary logs; client databases replicate from them as above. In my opinion both options are poor fixes for what ought to be a trivial change to the master to make it log to separate databases, but my opinions don't often count for much :-) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG
