OT: Maths Jam tomorrow
by Steve Engledow 17 Sep '12

17 Sep '12

Hi folks, Excuse the flagrant abuse of this mailing but I feel the crossover of interest is worth it. The first Norwich Maths Jam (see http://mathsjam.com) begins tomorrow evening (Tuesday 18th) at 7pm in The Reindeer pub on Dereham road; coincidentally a previous haunt of the ALUG pub meet :) If you fancy coming to a pub and being geeky in a mathsy way, come down! Remember kids, beer + geekery -> fun. Steve

apt-get problems
by Greg Thomas 16 Sep '12

16 Sep '12

I just tried upgrading from Ubuntu 10.04 to 12.04.1 (i.e. from LTS to LTS). It failed. The error message I'm getting is: An unresolvable problem occurred while calculating the upgrade: The package 'update-manager-kde' is marked for removal but it is in the removal blacklist. Google suggests that "apt-get remove update-manager-kde" should fix it [1], but that's giving me the following; Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libasound2: Breaks: libasound2-plugins (< 1.0.24) but 1.0.22-0ubuntu6 is to be installed libglib2.0-0: Breaks: gnome-control-center (< 1:3) but 1:2.30.1-0ubuntu2 is to be installed Breaks: gvfs (< 1.8) but 1.6.1-0ubuntu1build1 is to be installed libgnome-keyring0: Breaks: gnome-keyring (< 3.0) but 2.92.92.is.2.30.3-0ubuntu1.1 is to be installed libpango1.0-0: Breaks: plymouth (< 0.8.2-2ubuntu19) but 0.8.2-2ubuntu2.2 is to be installed ppp: Breaks: network-manager (<= 0.8.0.999-1) but 0.8-0ubuntu3.3 is to be installed Breaks: network-manager-pptp (<= 0.8.0.999-1) but 0.8-0ubuntu3 is to be installed E: Broken packages Have I completely hosed my setup, and is a fresh re-install due? Or is there a way around this? Thanks, Greg [1] http://www.hoaglun.com/blog/2011/5/8/ubuntu-1010-1104-upgrade.html

Default browser chooser script
by Mark Rogers 13 Sep '12

13 Sep '12

For day to day use I tend to use Firefox, and that's my default browser. That's more through "habit" than anything else and I frequently get frustrated by the amount of RAM its using etc. Occasionally I'll fire up Chrome or Opera, and one day I'll probably switch allegiances. In the meantime, what annoys me is that if I have (say) Chrome open and click on a link elsewhere (eg in an email) it'll open Firefox because that's my default browser. I'm sure it would be possible to write a script that checks to see if any browser is open, and sends the request there, only actually starting the default (Firefox) if no browsers are open. [Actually I think this ought to be the default behaviour for a range of apps; if I have a media player open don't open a different one if I double-click a media file, etc.] Any suggestions for where I should start? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Running vnc server on startup
by John Woodard 12 Sep '12

12 Sep '12

I want to run a vnc server on startup as a user rather than root and seek opinion to where the best place to put the command tightvncserver :1 -geometry 1280x1024 -depth 16 -pixelformat rgb565 etc/rc.local cron job? Not sure here really if it needs to be before login so thought it prudent to run as a user. Cheers, BJ

ALUG Announce Please send announcements to Announce(a)lists.alug.org.uk Unsub, change settings via http://lists.alug.org.uk/mailman/listinfo/announce ----- Hello Norwich Aluggers, Our monthly ALUG Norwich social meeting will be held this Thursday, 13th September at The Coach and Horses (82 Thorpe Road, Norwich, NR1 1BA). The meeting officially starts at 8pm, although some people may arrive earlier. More information on those people can be found on the list and the IRC channel. If you are unsure if you will recognise us then make yourself and your intent to attend known by either posting on list or visiting us on IRC so we can look out for you rather than hiding in the corner. Optionally you could ask at the bar if they know where the geeky computer weirdos are and they'll point you in the right direction (seriously!). Another possibility is look for heaps of electronics on a table that may possibly look like movie props that would used for detonating explosives. Feel free to bring electronics/laptops/gadgets to the meet, you will by no means be alone. Ben Bewick aka Viperfang NB: This mail is automated, please refer to the usual sources for more information.

Anyone know about and/or use libgda (gnome DB library)?
by Chris Green 05 Sep '12

05 Sep '12

While searching for ways to access databases I have hit upon libgda which is the Gnome generic DB access library. What has attracted me specifically is the gridWidget which appears to give me exactly the sort of interface to a DB table that I have been after for quite a while. (See http://www.gnome-db.org/ScreenShots at the bottom). Does anyone here have any experience with libgda? -- Chris Green

Re: [ALUG] Using Android phone as dial-up modem

It's possible to access the built-in modem capability on a GSII: http://forum.xda-developers.com/showthread.php?t=1471241 ..but not simple unless your phone provider includes host drivers (which it seems some do). Once you have the right modem device exposed, connecting it into PC Anywhere should be a breeze :) Or you can look at soft modems like SpanDSP: http://www.soft-switch.org/spandsp_faq/index.html http://www.soft-switch.org/spandsp-modules.html with the audio paths physically connected through your mobile from the sound card, but that seems a bit silly when the GSM baseband chipset can already provide what you want, if the manufacturer will let you use it.

How do I decide which printer driver to use in CUPS?
by Chris Green 04 Sep '12

04 Sep '12

I recently found that my printers were no longer working with one particular application (glabels). The error message from CUPS was "/usr/lib/cups/filter/hpcups failed" and a bit of Googling suggested that changing the printer driver selected in CUPS might fix the error.... and it did. I'm using the hpijs driver now instead of the hpcups driver. However it raises the question of how one decide which of many drivers available for a given printer one should select. For my HP1320 there's quite a lot to choose from:- HP Laserjet 1320 - CUPS+Gutenprint v5.2.8-pre1 (en) HP Laserjet 1320 Foomatic/Postscript (en) HP Laserjet 1320 Foomatic/pxlmono (recommended) (en) HP Laserjet 1320 hpijs 3.12.12 (en) HP Laserjet 1320 Series hpijs 3.12.12 pcl3, (en) HP Laserjet 1320 Series pcl3, hpcups 3.12.12 (en) HP Laserjet 1320 Series Postscript (recommended) (en) HP Laserjet 1320 Series Postscript (recommended) (en) HP Laserjet 1320 Series Postscript (recommended) (en) HP Laserjet 1320 hpcups 3.12.12 (en) ..., and yes, the Postscript one is repeated three times with no visible differences. So how is anyone supposed to decide which driver to use, I've not found any useful guidance anywhere. -- Chris Green
