GIMP and photo editing
by Bev Nicolson 23 Apr '14

23 Apr '14

This should be simple and usually, if I want to remove a splodge or mark from a photo I'd use Resynthesise. In this case I want to hide/remove a bit of flower but I've tried Resynthesise and cloning and neither really work. The first seems to use the flower next to it to copy its pixels rather than the soil/foliage and the second makes it look rather too obvious where 'surgery' has occurred. Anyone have an answer? Inkscape is not an answer! (In case you're tempted.) Bev.

Re: [ALUG] How to format numeric output from sqlite3?
by mark fernandes 18 Apr '14

YMMV with this as I'm not an sqlite guru... You may need to prefix the printf with a sqlite3_ . Elsewhere for mprintf example gives: char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText); sqlite3_exec(db, zSQL, 0, 0, 0); sqlite3_free(zSQL); HTH, Mark

SQL question for the SQL gurus out there
by Chris Green 17 Apr '14

17 Apr '14

I think there should be a way to do this but at the moment I can't see how, I always find SQL difficult to fathom though. I have a table with dates, times and temperatures in it. I want to select the maximum temperature for each year, how do I do that? The table has columns as follows:- ID Date Time Indoor Temperature Outdoor Temperature What I want to get out of it is something like:- 2014 21.23 2013 30.45 2012 25.31 It's a sqlite3 database so there's no procedural language easily available. I guess I could write a Python script to do what I want, that might be the easiest way. -- Chris Green

How/what does the Heartbleed bug compromise?
by Chris Green 17 Apr '14

17 Apr '14

I've just been discussing with my son exactly what is (seriously) compromised by the Heartbleed bug. I can understand the basics, it means that something encrypted using SSL (i.e. HTTPS protocol connections) can be decrypted by someone who shouldn't be able to do so. Having said that what can a 'bad hacker' actually do? There's a sea of packets flowing around the internet, picking out a series of packets relating to one 'connection' (i.e. with related information in them) is non-trivial as far as I can see, unless the hacker is sitting looking at the data flowing through a switch feeding one particular site. So, it's possible to hack/decrypt a single packet which I suppose *might* contain someone's login details if the username and password was in a single packet. Is this the extent ot the problem? If there's more to it than this can someone explain. For example MumsNet says it's been hacked as a consequence of this bug, I don't quite understand how someone could get at *all* the login details on MumsNet unless they fortuitously got an administrator's login details and the system is stupid enough to allow an administrator to get at all usernames and unenecrypted passwords. Surely quite simple (and well known) security practices would make this sort of thing much more difficult:- Don't send complete Username/Password details in a single packet, easy enough to do by asking for them separately or even crude padding. Don't store user's details in single, big, unencrypted files. Don't store unencrypted passwords anywhere, use the Unix login style of things so that what's stored is the result of encrypting the password and is difficult (as in requires loads of processor ooomph) to decrypt by brute force methods. -- Chris Green

How to format numeric output from sqlite3?
by Chris Green 17 Apr '14

17 Apr '14

OK, so having worked out how to extract maximum and minimum values for each year from my database (thanks Mark), how do I format them? Here's what I get at the moment:- Year MaxTemp MinTemp MaxOutside MinOutside 2010 14.0625 -0.9375 7 -7.6875 2011 25 -2.1875 41.9375 -8.6875 2012 85 -6.25 37.8125 -14.0625 2014 22.125 5.875 32.875 0.5625 It's actually presented as a table in DokuWiki but that doesn't really affect the issue. How do I get the temperatures shown in sensible, consistent format like NNN.N? According to http://www.sqlite.org/lang_corefunc.html sqlite has a printf() function but when I tried it I got an error saying "No such function: printf" and I can't find anything useful about it by Googling for the error or anything related. So any ideas, apart from horrible substr() manipulations? I *could* go into the Dokuwiki plugin I'm using to get the output from the database into tabular format, I've modified it a lot already, but it would be rather messy to do. So I'd like something I can do outside if possible. -- Chris Green

DLNA server that transcodes - any recommendations?
by Chris Green 14 Apr '14

I'm currently running minidlna as a DLNA server and it's fine except that it doesn't offer transcoding. I now have a client that doesn't understand FLAC so I need on the fly conversion of FLAC to MP3. Can anyone suggest a DLNA server that can do this? -- Chris Green

Update on ATI Problems
by Chris Walker 11 Apr '14

11 Apr '14

Well, it's up and running with my preferred desktop background, most of the applications are back, such as this 'ere email client, without having to set up all the accounts etc, but I have a problem which appears to be intermittent. The icons at the top right of the windows, minimize, maximise and close, keep disappearing. I'm very reluctant to go mucking about trying various files, just in case, so does anybody have any definite ideas as to what might be wrong please? The desktop is KDE 4.11 as I guess that's important. I've looked at, but not touched the plasma files in ~/.kde4/share/config but they don't seem to hold details of icons and the like. As it's all now working and before it all goes nipple north again, I'm about to do another backup. That way, if it all should go wrong, I know I can get back to a working state without having to download tons of updates etc. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

ATI Graphics failure
by Chris Walker 10 Apr '14

10 Apr '14

Hi, In the past couple of weeks, the screen of my Mageia4 (64bit) machine has decided it doesn't want to display any of the normal desktop icons or display at the full size. Having googled it, I discovered that ATI have moved the driver for my HD4670 card to legacy. So I went to their site and downloaded what they tell me is the correct driver but when I compile it, it's failing. I think the error is because the code is looking for v2.X kernels and not the 3.12 that my machine is running. If I look in the make log, it says this (excuse line-wrapping):- /usr/src/fglrx-8.97.100.7/2.6.x/drm_proc.h:98:2: error: implicit declaration of function 'create_proc_entry' [-Werror=implicit-function-declaration] It's the 2.6 bit in there that makes me think is looking for the wrong version of the kernel. Am I correct in thinking that, and if I am, what can I do about it? I should say that this sort of stuff doesn't come naturally to me and that it's taken me 2 weeks to get to this point, so a little hand-holding will be required! -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Subscription language
by Chris Walker 09 Apr '14

09 Apr '14

Following a sudden and very large increase in spam mail to a previous address used here, I've changed it slightly and of course, in doing so went to the lists web site. Just one question, why is the language set to English USA? As far as I know, they don't speak English, certainly it's not any English I recognise and I spent some time working over there ;-) As an aside, has anybody else noticed a large increase in spam to what was, a previously 'clean' address?

Asus EEE PC 900 partitioning
by Tony 06 Apr '14

06 Apr '14

I've acquired an Asus EEE PC that had windows XP on it. It has two SSD's, a 4 gig and an 8 gig and 1GB ram What I'm thinking of doing is partitioning as follows: 4GB SSD: /boot 250mb / (root) whats left 8GB SSD /usr 16GB SD card (class 6) swap 2GB /home whats left Would it be an idea to add /tmp and/or /var to the 8GB SSD or would you recommend a different schema? OS will be LXLE. I've installed LXLE but without the 16Gb SD card (using a 512mb SD card as swap to check it works okay which it does) but undecided how to partition for the final instal using the 16Gb SD card. Thinking of putting swap on the SD card as they are cheap and easy to replace and its easy to backup/restore whatever is on it. Probably not best performance wise but feel advantages out way disadvantages (i.e. less wear/leaves more room on SSD, cheap and easy to replace. will allow hibernate function) Not sure what I will use it for yet, probably mainly surfing, emails and watching movies on the move or from separate mythtv backend using VLC. A lighter OS such as AntiX would probably be better suited but I'm trying to use the same distro on everything (laptops, desktops & netbooks) and LXLE is my preference. I also have squid-deb proxy set up to cache updates. So far liking it more than my Android tablet :)

Going back to VPNs - when I have one set up what does it do for me?
by Chris Green 25 Mar '14

25 Mar '14

I keep thinking that a VPN might be what I need, but then when I look at VPN documentation etc. I wonder whether it is what I need. So, if I set up an OpenVPN server on my home desktop machine (which stays turned on all the time) and set up access for me as a client from my laptop, what does it mean that I could do that I can't do already? Or, maybe more to the point, what does it make it easier to do? (Note that my home desktop is visible at a fixed IP address from the outside world and I can open up any additional ports through the firewall if necessary.) -- Chris Green

Strange 'bandwidth strangulation' when using ssh on DFDS public WiFi
by Chris Green 24 Mar '14

24 Mar '14

When this first happened to me I thought it was just a one off oddity but yesterday when I returned on the ferry from France I saw *exactly* the same symptoms on two entirely different systems. It's hardly a big issue either just an inconvenience but I'd love to know why it happens. On the DFDS ferries there is free WiFi available, no hassle, no login required, just an open SSID called DFDS-Pax. My laptop (running Ubuntu 13.10) and my tablet (Android 4.x) both connect to it quite happily. It's reasonably usable as well, hardly lightning fast, but fine for browsing web pages etc. However if I try and connect (from either tablet or laptop) using ssh it starts off OK but after some hundreds of characters it just slows down and stops never to pass another character. If I open another ssh session from the same device the same thing happens, i.e. it gets another few hundred characters through. It's not very consistent, sometimes it doesn't even manage to complete the ssh handshake sequence, but most times it gets to a command prompt and allows me a couple of commands before going to sleep. Anything that generates a lot of traffic (like starting up mutt) always hangs before it gets anywhere but a couple of 'ls' commands will sometimes work. So what might be going on? It's not like ssh protocol is blocked completely so it's not that the port(s) are blocked, it's almost as if there's someone watching and, when they can't see what's being transferred, they stop the data. Any ideas anyone? I suppose I could try a different port for ssh but as it's not specific port blocking I don't think this will fix it. ... and as I said, it's not very important, I don't often want to read my E-Mail while crossing the channel! :-) I'm just curious. -- Chris Green

Running PHP programs
by Chris Walker 23 Mar '14

23 Mar '14

I want to run Geneotree (http://www.geneotree.com/) so I downloaded it and extracted the files from the zip. I'm not familiar with PHP stuff so I put them in /home/chris/geneotree. There are lots of php files and a few folders but how do I run the thing? There's a config.php file which contains these lines :- ============= <?php /******* PLEASE DON'T MODIFY THE FOLLOWING LINE - NE PAS MODIFIER LA LIGNE CI-DESSOUS SVP ********/ $INSTALLATION_OK = FALSE; /*************************************************************************************************/ /****************************** BEGIN INITIALIZATION CONNECTION PARAMETERS ***********************/ $sql_host = 'localhost'; $sql_base = 'geneotree'; $sql_user = 'root'; $sql_pass = ''; /******************************* END INITIALIZATION CONNECTION PARAMETERS ************************/ ?> ============ Do I need to modify any of them to run it? I'm told that there is documentation on sourceforge but I can't see anything that would help me. I've tried putting htpp://localhost/geneotree in a browser but it fails which is not unexpected. So at this point, I'm stuck and any help would be appreciated.

Why isn't rc.local getting run? (some sort of runlevel oddity?)
by Chris Green 20 Mar '14

20 Mar '14

I am having trouble getting things in /etc/rc.local to run. As I understand it this *should* be the standard way to make local additions to be run at startup. This is on an Ubuntu 13.10 system runnning on a Beaglebone Black so is maybe a little out of the ordinary. As I understand it /etc/init.d/rc.local gets run by the system startup process and, if there's anything to be run in /etc/rc.local that will be run. This doesn't appear to be happening. If I run '/etc/init.d/rc.local start' manually then the contents of /etc/rc.local get run and there are no errors. So it would seem that for some reason /etc/init.d/rc.local isn't getting run at system startup. The system runlevel is 2. I'm sure that /etc/rc.local should be run at every run level so I don't see how this could affect it. So, what's wrong, or misconfigured? -- Chris Green

wireless broadband in Norfolk

All I know that some people on this list have poor (or even very poor) broadband connectivity. I have just discovered http://www.thinkingwisp.co.uk This company purports to offer wifi broadband over large parts of the county. Their offering looks expensive to me, but then I'm fortunate in having good connectivity at home. However, if you currently have problems then this /might/ be of interest. Note - I have no connection to this company, nor any commercial interest. (Nor do I know if the service is any good....)
