Android updates for cheap tablet
by Mark Rogers 20 Aug '12

20 Aug '12

I have a cheap Android tablet, branded Synapse, I think it's this model although I paid nothing like that for it: http://www.dee-sign.co.uk/products/synapse-tablet-top-spec What are my options for playing with Android versions? I'd like to experiment with (eg) CyanogenMod but haven't done it before; I was thinking it better to risk my cheapo tablet than my Galaxy SII but on the other hand at least the GS2 has been well tested... I believe the tablet is just the same as any number of cheap imported tablets and I don't want it to be stuck on the version it shipped with (albeit that it came with ICS). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Keyboard and mouse 'crash'
by Bev Nicolson 19 Aug '12

19 Aug '12

Every so often (not too often happily) both keyboard and mouse will stop functioning. It seems to happen most often when I plug a camera or MP3 player in. The only way to get them going again is to switch everything off. (If I touch the off button it will shut down in 60 seconds from the shut down dialogue box.) What I'm wondering is, has anyone here come across this problem and is there another, more permanent, solution to it? I would add that I've never had to install any drivers for any such devices, so I'm pretty confident that's not the issue. [Unbuntu 11.04.] Bev.

Wanted - algorithm for bufferless search for a pattern in a stream
by Chris Green 08 Aug '12

08 Aug '12

I can see how to do this in principle but I can't iron out the details and I'm sure there must be some ready made code for doing it 'out there' on the internet. It's just rather difficult to come up with search terms when I don't know what to call it. To explain in detail I want to search for a (constant) string in a byte stream that I can't rewind and I don't want to use any significant buffer space (the constant string I'm looking for is quite long). So, obviously one reads a byte at a time from the stream to see if it matches the first character of the constant string, if that matches one moves on to the second, etc. When the whole string has been matched then it's found - so far so good. However, when a character *doesn't* match one can't go back up the input stream, *but* we know the previous characters as they're the ones in the constant string that we have matched so far. Thus we can 'wind back' by using the constant string for the number of characters that did match and then continue down the stream. If anyone can follow that rubbish explanation then could they possibly tell me what the algorithm is called and/or point me at some sample code? -- Chris Green

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, 9th August 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.

Forcing "Sender:" in exim4
by Ted.Harding＠wlandres.net 05 Aug '12

05 Aug '12

Greetings All! I have just (!!! -- after about 4 years ... !!!) that in my Debian Etch setup 'sendmail' is aliased to 'exim4': ls -l `which sendmail` /usr/sbin/sendmail -> exim4 My mailer (MUA) setup presumes sendmail. I have configured the MUA so that, in the headers for outgoing mail, I have set: Sender: ted.harding@wlandres (same as my "From:" and "Reply-To:" addresses). That is how the header appears while the message is still in the "outbox" folder. However, when I send the mail out, it seems that exim4 changes the "Sender:" address to "ted@deb", "deb" being the name of my machine on my home LAN (as set in /etc/hosts), and "ted" being the user. As a result, when the mail is received outside my LAN, the receiving host sees the header: Sender: ted@deb instead of what I want it to be! This sometimes results in rejection when the receiving host does not recognise the sender domain. Now, while I know my way round sendmail itself, I find I am disorientated by trying to make out how to customise exim4 configuration. (I've tried reading the man pages). What I want to do is ensure that exim4 (aliased as 'sendmail') either does not change the "Sender:" header as it is while still in the outbox, or else sets it anyway to Sender: ted.harding(a)wlandres.net And it could also be useful, though not essential, if, should I happen to mail as a different user on the same machine, e.g. "efh", it could preserve the domain and insert the user, e.g. Sender: efh(a)wlandres.net My mind is blank about how to set about configuting exim4, so I need very basic instructions (preferably with outline explanation). Maybe a configuration file (where and how?) change, or a command line option to exim4 (the latter is probably simpler for me, since I can enter such options in my MUA setup). With thanks! Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 04-Aug-2012 Time: 17:07:50 This message was sent by XFMail -------------------------------------------------
