Long UTF-8 message in Subject!!!
by Ted.Harding＠manchester.ac.uk 12 Jun '09

12 Jun '09

Greetings, Folks! This morning I received a message from the local Police via the Cambs "ECops" mailing list (which I subscribe to -- it's a sort of community bulletin board for local policing matters). The message itself was in effect empty -- just the statutory "footers" that appear in every such message. The subject-line (as displayed on my mailer) just said: =?UTF-8?B?RS1Db3BzIC0gVGl0bGUgLSBBY3Qgbm93IGFuZCBhdm9pZCBhICdjYX But then I opened up the full headers. Lo and behold, there was a massive Subject: therein! It would seem that the sender had typed the entire message into the subject-line! However, not only does it claim to be UTF-8, but is also somehow encoded. I can't make it out. So your puzzle for the weekend is to find out what it says! It's unsuitable (lines too long, and some already broken anyway) to paste into the body of this message, so I'm attacheing it as a plain-text file (but exactly as it came up on my screen) subject.txt Any takers?

To be honest I don't really care if it takes a couple of hours to do the actual conversion (although I'd expect something quick, like you suggest). It's the trial & error bit that's the bit I'm trying to make simple; the problem is I don't know how many millisec I need to shift the audio, I just know that it's wrong at the moment! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

AV manipulation
by Mark Rogers 09 Jun '09

09 Jun '09

I have two AV tasks I need to perform, which are otherwise unrelated... 1. I have some video for which the sound is out of sync. The video files use an XviD codec (not sure what sound codec). I'm looking for a tool to allow me to correct them. Ideally I want something I can just use left/right arrow keys to jog the sound a small amount ahead or behind the video until it's correct, then hit save to create a new file. It all ought to be pretty quick (no recompression needed, just re-synchronising). Any suggestions? 2. I want to take some audio files and slow them down (quite a lot) without changing their pitch. I'm trying to learn to play the guitar and I can't play fast enough to play alongside anything yet unless I can slow it right down! My desktop is Ubuntu 9.04 if that's relevant. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG

Printing suddenly changed to monochrome only
by Barry Samuels 07 Jun '09

07 Jun '09

I have recently changed over to CUPS in my Debian system although I don't think that caused the problem. I have an HP Colour LaserJet 4500 which will happily print a test page from the printer menu which includes colour so no problem there. However in the CUPS setup the only options I get are 'Grayscale' or 'Inverted Grayscale'. The driver selected is 'HP Color LaserJet 4500 - CUPS+Gutenprint v5.2.3 (en)' and the printer will print only in monochrome. Any ideas? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Eee and root
by Anthony Anson 07 Jun '09

07 Jun '09

To install a program I presume I have to be root. I can't remember ever giving the Eee a root password, nor for that matter, ever being asked for one. I want to put a link to Thunderbird on the 'Internet' page, but I can't drag the icon (kicking and screaming, or not), nor can I copy and paste the icon. Unfortunately, I've filed the book of destructions 'somewhere safe'... HELLLLLP! -- Tony

Globbed search for filenames in website
by Ted.Harding＠manchester.ac.uk 07 Jun '09

07 Jun '09

Greetings! I'm looking for a way to find out what files for a particular wild-card form exist at a certain directory depth on a website. For example: www.some.web.page/*/*.png for all PNG files 1 below the top level. The results to be listed (stored in a file) along the lines of what you would get from ls */*.png if you were at the top level on the server. A browser won't do it (won't accept wild-cards). I've looked at wget, but this doesn't seem to have a simple listing option (except under ftp mode, which the remote site won't respond to). Any suggestions? With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 07-Jun-09 Time: 08:41:32 ------------------------------ XFMail ------------------------------

fcron or anacron
by Peter Alcibiades 04 Jun '09

04 Jun '09

Have you ever used either of these? I want to use fcron to run a command every 20 or 30 hours of machine uptime, but cannot figure out exactly where to put the command or how to get it there. Peter

Mark, >What I have so far is: >SELECT tbl1.email AS email1, tbl2.email AS email2 >SELECT IF(tbl1.email IS NOT NULL, tbl1.email, tbl2.email) as email >FROM tbl1 LEFT JOIN tbl2 USING (email) > >.. which will get me all the addresses from tbl1, with the matching >address from tbl2 in email2 or NULL if there is no match. > >What I want is to also get all the addresses in tbl2, with NULL against >email1 where there is no match. That is what I thought an OUTER join did >but it seems I'm wrong. An OUTER join can be a LEFT or RIGHT join like this: SELECT tbl1.email AS email1, tbl2.email AS email2 FROM tbl1 LEFT OUTER JOIN email2 USING (email); will show you all the records from the left table (in this case tbl1) and NULL for any records that didn't appear in the right table (tbl2). Perhaps what you want is a union query: SELECT DISTINCT email FROM tbl1 UNION SELECT DISTINCT email FROM tbl2 ORDER BY email; This should give you one result for each distinct entry between the two tables, if I understand it correctly. Worked for my (admittedly very small) test db. Hope this helps, Jim

MySQL Joins
by Mark Rogers 03 Jun '09

03 Jun '09

I'm not even sure if this is possible, but I have two tables containing email addresses, some of which are common to both tables. Is there a way I can extract a merged set of addresses from both tables in one go? What I have so far is: SELECT tbl1.email AS email1, tbl2.email AS email2 SELECT IF(tbl1.email IS NOT NULL, tbl1.email, tbl2.email) as email FROM tbl1 LEFT JOIN tbl2 USING (email) .. which will get me all the addresses from tbl1, with the matching address from tbl2 in email2 or NULL if there is no match. What I want is to also get all the addresses in tbl2, with NULL against email1 where there is no match. That is what I thought an OUTER join did but it seems I'm wrong. (Once I have a set of results containing 2 fields, where every address in each table appears, I can easily merge the two fields using an IF.) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG
