automount of USB drives not working - where should I look?
by Chris Green 22 Feb '12

22 Feb '12

I've just discovered that automounting of USB drives isn't working on my xubuntu 11.10 system. I can see the device with lsusb:- Bus 002 Device 005: ID 0951:1607 Kingston Technology DataTraveler 100 but no sign of it automounting. The "Mount removable drives when hot-plugged" setting is ticked and it always used to work (though I'm not absolutely sure it has worked since I upgraded to 11.10). Any ideas? -- Chris Green

SQL question, I suspect I need some sort of inner join
by Chris Green 21 Feb '12

21 Feb '12

I have a sqlite table of temperatures with columns as follows:- id, Date, Time, Inside_Temperature, Outside_Temperature How do I get the date and time for the minimum and maximum temperatures for a specific year? It's easy enough to get the required temperature:- SELECT min(Inside_Temperature) from temperatures; ... and even to get the Date and Time associated with that:- SELECT Date, Time FROM temperatures WHERE Inside_Temperature = (SELECT min(Inside_Temperature) FROM temperatures); However if I want to find the minimum temperature in 2012 I'm a bit stuck. SELECT Date, Time FROM temperatures WHERE Inside_Temperature = (SELECT min(Inside_Temperature) FROM temperatures WHERE Date like '2012%'); ... returns dates in other years where the temperature happened to be the same. I can make the outer SELECT only look in 2012 but that's beginning to get a bit messy. Is there an easier/better way where I join using the id which matches the minimum temperature to select the other columns I want? -- Chris Green

Off topic: dot IT domains
by John Woodard 20 Feb '12

20 Feb '12

Sorry if this is slightly off topic but I know the collective wisdom out there will know the answer to this one. Who is a good uk agent to reg a .it domain? The usual bulk reg sites like 123-reg don't seem to do them. Cheers, BJ

Strange lack of PHP error reporting
by Chris Green 14 Feb '12

14 Feb '12

I'm having a real hard time at the moment because for some reason PHP errors (in web pages) don't seem to get reported anywhere. I've narrowed the problem down a bit, if I put a PHP file in my root web directory then any errors *are* reported. However if I put an error into some of the code in my wiki nothing happens except that I get a completely blank page. I've looked at the .htaccess file, no joy there, doesn't set anything relevant. There's nothing appearing in the apache log file either, total silence. Any ideas? -- Chris Green

How to set permissions on an ethernet port?
by Chris Green 14 Feb '12

14 Feb '12

How can I set the permissions on eth0 to allow me (as opposed to root) to modify it? I want to use macchanger from a script and I don't want to have to enter my password every time I run the script. I assume it's the same sort of permission that one would need to be able to use ifconfig to change things on a network interface. -- Chris Green

I may have a book on it, I may have the online manual but can I get GIMP to heal a smudge on a photo? Not so far. Anyone got any tips? Many thanks. Bev.

Hmm I have had that a few times with the built in Gnome burning....k3b however has been good to me over the years even if it does need a million KDE libraries installed.

Regular expression question
by Chris Green 08 Feb '12

08 Feb '12

I want a regular expression to select text between /x and /, e.g. I'm wanting to look at something like:- /x This is a load of multi-line text and some more and more / ... and get the three lines of text (with/without the end bits). However I want it to be non-greedy so that:- /x Here is some text / and some more / ... will return only the "Here is some text" bit. So, a simple regular expression like '^/x[^/]*/' gets me what I want. However, I'm trying to make this a bit cleverer so that embedded / characters don't break it. So the next try is '^/x.*/\n', this works to an extent but it's 'greedy' so giving it the second example means that it returns both "Here is some text" and "and some more". Is there a way of saying "not /\n", or any other way of saying 'non-greedy'? This is using PHP regular expression searches. -- Chris Green

Distro for ARM
by Dan 06 Feb '12

06 Feb '12

Dear All, I currently have a fairly minimal Gentoo install in a chroot, on my ARM-based Android 'phone. The reason it's fairly minimal is that compiling additional packages is very slow. Hence, I've decided to replace the Gentoo install with a binary distro. I've got debootstrap installed under Gentoo, and am ready to go - but I'm a little confused as to what architecture I need to tell debootstrap to install for, since as I understand it, not all ARM binaries will run on all variants of ARM processor. Can anyone advise, please? The specific processor is a Qualcomm MSM7200A, and the compiler options I use in Gentoo are: CFLAGS="-march=armv6 -mtune=arm1136j-s -mfloat-abi=soft -O0" (the -O0 was a vain attempt to reduce compilation times to a manageable level.) -- Thanks, Dan
