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 Aluggers, Our monthly ALUG Norwich social meeting will be held this Thursday, 8th 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.

A couple of git questions
by Chris G 02 Sep '11

02 Sep '11

While using git over the past few weeks a couple of questions have arisen. 1 - When doing a 'git commit' where does one, by convention, put the comment? Does it go before all the comments, after them, or what? I know it doesn't actually matter at all but I'd still like to know. 2 - What is 'git diff' invoking as a pager, and why? E.g. see the following:- chris$ git diff mychanges stable diff --git a/lib/plugins/config/settings/config.class.php b/lib/plugins/config/settings/config.class index 5075c60..01f15a5 100644 --- a/lib/plugins/config/settings/config.class.php +++ b/lib/plugins/config/settings/config.class.php @@ -774,8 +774,8 @@ if (!class_exists('setting_dirchoice')) { if ($entry == '.' || $entry == '..') continue; if ($this->_pattern && !preg_match($this->_pattern,$entry)) continue; - $file = (is_link($this->_dir.$entry)) ? readlink($this->_dir.$entry) : $this->_dir.$fil - if (is_dir($file)) $list[] = $entry; + $file = (is_link($this->_dir.$entry)) ? readlink($this->_dir.$entry) : $entry; + if (is_dir($this->_dir.$file)) $list[] = $entry; } closedir($dh); } (END) That (END) is a prompt waiting for me to do something to exit. This is on a 60 line high terminal window so the pager is unnecessary anyway! The real problem was that it took me quite a while to find out how to exit. -- Chris Green

Church WiFi
by ted.harding＠wlandres.net 01 Sep '11

Hi Folks, Back in the early 2000's, when Internet access in my Little Ouse/Brandon Creek area was limited to painfully slow dialup (not to mention many other remote places throughout East Cambs and North/West Norfolk), I remember discussing with fellow nutters in the Anglia Linux Users Group the feasibility (as I wrote at the time, Feb 2002) of the following: Come to think of it, ALUG should be a damn good place to ask this question ... A friend of mine, much knowledgeable, tells me that with directional antennae a line-of sight range of 10-15 miles should be attainable for wireless LAN. But it's equally a question of finding hospitality at the far end. Well, out here in the midst of optically flat nowhere, line of sight to almost anywhere is no problem. Problem is, almost everywhere is uninhabited. Nearest place which might have an accommodating college or such is Ely (10 miles, but on a nice mountain which boosts line-of-sight visibility). So there you are. I'm groping. But there must be some of you who've at least thought about this in similar terrain; so if anyone has any comments or suggestions I'd be most interested to hear! It might lead to an improvement on my current 33.6K bit rate ... and, come to think of it, converting Ely Cathedral to a LAN hub is a tempting notion. Best wishes to all, Ted. Well, the Broadband Revolution has rendered such thoughts obsolete at the Brandon Creek exchange, of course. But a news story this morning revives the notion, and has inspired me with a new twist to the idea. http://www.bbc.co.uk/news/uk-england-norfolk-14734574 Inquiry into Norfolk church WiSpire scheme Plans to use church towers in Norfolk to transmit wireless broadband signals to provide better internet access for rural areas have stalled. [...] The scheme is a venture by the diocese and internet service provider Freeclix. Wireless receivers would be installed on church spires, acting as high spots, to give nearby businesses and homes access to high-speed broadband. Wi-fi hot spots would also be created in churches. So it seems there is still scope for my original concept out there in Norfolk. But I have a bigger concept now. These days, most people have Wireless Internet enabled mobile phones, so can be in contact wherever there is a signal. Not forgetting all those home computers. Which prompts me to think that we no longer have a need for priests and parsons to communicate with the Almighty. And the proposal that "Wi-fi hot spots would also be created in churches" is based on a narrow and outdated vision. I do not believe that God is so obsolete that he can't fill the Universe with WiFi signals, and receive any that are transmitted. He created all this stuff in the first place, and has been ahead of us ever since (though we may be starting to catch up). So, from now on, if you want to communicate with Him, just switch on your mobile and dial the Divine Number (which is not "666" -- that connects you to a different Infernet Service Provider). Then the ancient channels of Priest and Parson (whose information transmission rate has been stuck at about 0.001 bits/sec for millennia) can be closed down, and their infrastructure put to better uses (as seems to have been the idea behind the WiSpire idea in that news item, though still based on backward thinking). Then you can talk directly to God, and He can talk directly to you. If you pray ever so nicely, perhaps He will favour you by setting up a cosmic Internet hub, which will route all wireless communications from anywhere in the world to anywhere else in the world. All He needs to do is to will it, and it will happen. Onward!

Updating Seamonkey
by Bev Nicolson 31 Aug '11

31 Aug '11

So, the best way of upgrading Seamonkey would be (I guess) via Synaptic, except Synaptic doesn't have the most up to date version available. <<apt get install>> followed by the version ? Or not? Thanks. Bev.

Full swap space on vm
by Jenny Hopkins 29 Aug '11

29 Aug '11

Hullo there, I admin a vm with Bytemark, and am wondering why the swap is showing as full. Htop shows Mem usage to be roughly half (out of 984MB), but swap is at 255/255MB and hasn't shown any signs of changing for several hours now. vmstat procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 262116 237032 58540 258224 2 1 5 1 4 4 19 10 69 2 swapon -s Filename Type Size Used Priority /dev/vdb partition 262136 262116 -1 cat /proc/sys/vm/swappiness 60 Is there any way i can see what the swap is full of, or why it is full when there is plenty memory available? Thanks, Jenny

Load averages
by Mark Rogers 23 Aug '11

23 Aug '11

I've been playing with monit[1] to monitor a server which has been having some problems (specifically a service would stop responding to TCP requests, so although it was still "running" it was no longer any use; monit is able to make connections periodically and check whether or not the they're being accepted and giving the expected response). It comes with an example configuration for monitoring the system (memory/swap/cpu usage, and load averages). I have it monitoring load averages based on the configuration but I'm getting a lot of alarm reports every day and I need to tweak the config. The existing config is fairly self explanatory: if loadavg (1min) > 4 for 2 cycles then alert if loadavg (5min) > 2 for 2 cycles then alert On other words, if the 1 or 5 min load averages exceed the level shown for two or more consecutive tests (which take place every 2 mins) I'll get an alert. My question is: what would be sensible load averages to set the thresholds at, or are they essentially meaningless and I should ditch them? The server has a AMD Athlon(tm) II Neo N36L Dual-Core Processor so as I understand it a load average of anything up to 2 means the CPU is under-utilised anyway?

Has to be the flatpot because the hi-fi isn't portable, neither is the (full) tower with Lenny on it. Tower's upstairs and hi-fi's down. The record should be mono (1961), so I'll experiment with the headphone jack and the amp set to mono - output there is on volume control, and I have a suitable cable for that. -- Tony Anson www.girolle.co.uk/
