In-kernel memtest
by Dan 14 May '11

14 May '11

Dear All, I have in-kernel memtest enabled. It lets me know it's there at boot time by writing the stuff I've appended below to /var/log/messages. But can I expect it to write something to a log anywhere if and when it finds and isolates any faulty RAM? -- Thanks, Dan 2011-05-08T12:29:09.957840+01:00 hydrographer kernel: [ 0.000000] early_memtest: # of tests: 17 2011-05-08T12:29:09.957865+01:00 hydrographer kernel: [ 0.000000] 0000010000 -

It's directly opposite the town's central library and has a reputation for good Irish beer. We're usually to be found in the lowest section of the bar, near the library entrance to the pub. All are welcome, novices and experienced users. Feel free to ask for further information on the Main ALUG mailing list. Hope to see some of there!

Fwd: ASDA online shopping -- website doesn't seem to like linux?

My letter clearly did some good. I tried Asda a few weeks later and all worked ok again. However, as someone said Tesco are better for online shopping [not that Waitrose are bad but that much more expensive]. A letter of complaint is taken seriously these days if written appropriately. I remember my bitter experience Virgin media and their cunning "auto-upgrading" on broadband. Of course i had no proof until in one of the reply letters was an admission - next time i had a letter from the debt collection company i replied with a copy... no further communication. [Should anyone have any trouble you must continue to communicate with a dispute... debt collection cannot touch you]. james

Re-sent cos this PC defaults to Rich Text. Sorry Admins. From: keithjamieson(a)hotmail.co.uk To: main(a)lists.alug.org.uk Subject: RE: [ALUG] JTAG Date: Thu, 28 Apr 2011 18:05:28 +0100 Mark JTAG is used to use a PC to program an embedded device. I have made one the parallel port of a PC to recover my Linksys WRT54G. It also, I think, can be used to debug the device. Its a "standard" which is adopted by manufactured, althought I have not heard of the newer one you mentioned. But I have not been in this field for some time! In the older times you would remove an EEPROM and pur it into a programmer, then put it back into your device. This is the lead to illiminate that need. Keith

Changing the location of an SVN repo
by Mark Rogers 10 May '11

10 May '11

Assume I have an SVN repo accessed via http at http://svn.example.com/svn/myapp. The URL http://svn.mycompany.com/svn/myapp is an alias for the above (ie same server, same login details). How do I tell an svn client that's already checked out a working copy to use the new URL given that nothing apart from the URL is changing? As an aside, if the new URL was on a different server with different user/pass but contained an identical repository (with a view to moving to a new host), how would that affect things? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Is there anything 'ready made' to add suffixes to ordinal numbers (in dates in particular)?
by Chris G 09 May '11

09 May '11

I'd like to output dates like:- 1st September 2009 23rd August 1967 I.e. I want the 'st' and 'rd' suffixes for the day. It doesn't look like strftime() offers an option to do this. I can obviously do it myself with a switch/case or some if/then/else statements but I was wondering if there's anything ready-made that I've missed. -- Chris Green

The 'Elite' Man
by Chris Walker 09 May '11

09 May '11

If anybody here remembers David Braben, he's active again with something different from Elite. Take a look at http://www.raspberrypi.org/ When I looked at it, I had in mind Chris Greens webcam on his boat and whether something like this could be used. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

TCP/IP logging
by Mark Rogers 09 May '11

09 May '11

I have a simple application which connects to port 50000 on a Linux box, communicates, then disconnects. I'd like to log the entire communication in each direction in an easy-to-read format so that I can see what is going on. The protocol is ASCII but with a few control chars thrown in (eg STX/ETX/ACK/etc, and I wouldn't like to rule out NULL chars ever appearing in the data). I can easily run the server side at (say) port 50001 instead and have "something" listen on port 50000 and connect to port 50000 and pass the data back and forth between the two, logging it as it goes, although I don't know what to choose for "something". Or I could look at Wireshark, which I've played with in the past but never in anger, and my general feeling is that unless I learn how to sort the trees from the wood then this is going to give me too much information and I'm going to spend more time sorting through it than I do resolving the issues in the protocol. Or maybe there are better alternatives altogether! [If it's relevant: the Linux server has no GUI but is a VirtualBox virtual machine on another Linux server that does have a GUI where I could run Wireshark. The device connecting to the server is not a PC and has no diagnostic capability built in.] -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

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, 12th May 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.
