Lenovo T520
by Paul Grenyer 02 Jul '12

02 Jul '12

Hi All I'm still having lots of wifi and 3G card related problems with my Lenovo T520 and Linux Mint 13 (I though it was 12, it was 13). Does anyone have a similar machine (or even the same machine) that they're successfully working with? Maybe I could pick your brains at one of the pub meets? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer ACCU Member: License to code.

Open source alternative to full fat Adobe?
by Bev Nicolson 26 Jun '12

26 Jun '12

Evince is great for what it does, imo, but you can't extract pages with it. Does anyone round here know of a good alternative to the full-fat, all singing all dancing but not very cheap Adobe? Does such a thing exist? Bev.

SOund unavailable on Flash Player
by Ted.Harding＠wlandres.net 24 Jun '12

24 Jun '12

Greetings All! Just now, wanting to play a YouTube video, I found that the sound on Flash Player is turned off, and I can find no way to turn it on again. The "speaker" icon in the bottom bar as an "X" beside it, indicating that it is turned off, and I can find no way to turn it back on again (e.g. clicking on the icon, or on the "X", produces not response; and looking into Settings after right-clicking on the Flash Player screen offers no help). However, everything was fine a few days ago, and I'm not aware of having done anything which might cause this problem. Also, the YouTube video is indeed the same one which I had watched a fews days ago with no problem. Can anyone offer any help with this problem?

Wierd hang(s) when using grep
by Chris Green 20 Jun '12

20 Jun '12

Over the past few months I've noticed that when I run grep it sometimes appears to hang, I had put it down to doing "grep -r" down a rather large file hierarchy but now it's happening with a perfectly simple grep:- www-data$ ls *.txt sidebar.txt start.txt www-data$ grep xxx *.txt www-data$ grep fred *.txt www-data$ grep 'CLEARFLOAT' *.txt ... and there it sits, still (like 5 minutes later). The two .txt files are only a few tens of bytes long. It's not using any processor time, it's just stuck. I have just done it again in another terminal window, quotes removed but otherwise the same:- www-data$ grep fred *.txt www-data$ grep CLEARFLOAT *.txt ^C www-data$ ... and with a different user (in the same directory):- chris$ cd /home/www-data/www/wiki/data/pages chris$ grep fred *.txt chris$ grep CLEARFLOAT *.txt ^C chris$ So, what am I missing? -- Chris Green

Getting MAC address in a shell script
by Mark Rogers 20 Jun '12

20 Jun '12

This works: mac=$(ifconfig eth0 | grep -Eo '..:..:..:..:..:..' | sed -e 's/://g') .. but I'm sure there's a better way. Suggestions? Also, if I have something like: echotemplate="This is my MAC: (MAC)" mac=$(ifconfig eth0 | grep -Eo '..:..:..:..:..:..' | sed -e 's/://g') echo $(echo $echotemplate | sed -e "s/(MAC)/$mac/") .. is there a better way to do the substitution in the last line? I can't swap the top two lines around (one is a user-defined setting at the top of the script, the value of $mac is calculated in the body of the script), otherwise I would just use echo "This is my MAC: $mac" .. which would be nice and easy! But I'm using this as a learning exercise. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Getting round lack of suid on scripts (not to become root!)
by Chris Green 20 Jun '12

20 Jun '12

Is there any way to run a script such that it executes as another user than the person running it? Normally (well, old-fashionedly) one would have set the SUID bit in the permissions, made the script owned by the desired user and that would be it but nowadays it no longer works because SUID on scripts is disabled. Is there any reasonably simple way to work round this? All I have found searching so far is to write a short C program to do the SUID change and use that to execute the script. I could do this I suppose but I'd really prefer an easier way to do it as the C program method needs to know both the desired UID and the name of the program to run so, while hardly complex, it will need command line parameters etc. -- Chris Green

Does anyone here know how gmail works?
by Chris Green 19 Jun '12

19 Jun '12

I am trying to sort out moving someone else's hosting. The web hosting has transferred fine along with the domain hosting but I'm a bit stuck with their E-Mail. I have their name/password for logging on to gmail but when I try and change things it just says:- Manage account information Google can't change personal information for jane(a)reshapers.org. To change the information, contact your reshapers.org administrator. Learn more ... er, but the reshapers.org administrator is now me and I haven't any idea how the E-Mail *was* getting to gmail from the old hosting account. Presumably there was some cleverness with MX settings or something but it seems a wierd way of doing things. Is there some sort of 'hidden' gmail address that a user has on gmail that I can forward mail to from the new hosting site? -- Chris Green

svn file "sets"
by Mark Rogers 18 Jun '12

18 Jun '12

I have a library of code already in svn. I want to create subsets of it that I can either export or checkout, so that I only download the files needed for a specific job. I know about (by reading[1], not doing) sparse checkouts, eg: cd C:\path\dir svn checkout https://server/path/to/trunk/dir/dir/parent_dir--depth empty cd C:\path\dir\parent_dir svn update filename.log (Edit filename.log) svn commit -m "this is a comment." (Copy and paste from an example, hence the Windows-esque paths, although I'm only working on Linux myself.) This will do what I need, except that I'm looking for a simple way to replace "filename.log" in the example above with a name for a set of files. Depending on what I'm trying to do, I might want to export that set of files rather than do a checkout.
