Robolinux
by Chris Walker 28 Apr '14

28 Apr '14

Hello, I've just downloaded and installed a copy of Robolinux on a spare desktop machine. It says that it's a replacement for Windows XP as it will keep the Windows stuff secure without fear of a virus or malware. I paid a few dollars for the basic version as I thought I would be able to configure the XP stuff myself. But it seems they want me to pay for more of it first. But then the thought occurred to me that I might be able to do all this stuff with VirtualBox anyway. This is the link to the info about the secure bit - http://www.robolinux.org/stealth-vm-info/ There's a video on the site showing how a virus attacks the VM. What I find more than a little annoying is that it says I can do this for free and yet there's no way to get past the donation page. The question remains though. Is this special software or simply a cunning bit of configuration of a virtual machine on the part of Robolinux? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Syntax problems
by Chris Walker 26 Apr '14

26 Apr '14

Hello, I need more help please. I'm trying to make my machine convert some .ogg files to mp3 using twolame (my distro doesn't have lame, only twolame) and I'm trying to do it like this :- for t in {01..15}*.ogg; do twolame -b 320 $t $t.mp3; done but it's failing with this message 'Usage: twolame [options] <infile> [outfile]' All the filenames are like this '02 - I Close My Eyes And Count To Ten.ogg' with perhaps 15 or so tracks per folder. In order to find my error, I tried this - for t in {01..15}*.ogg;do echo 'found tracks '$t;done and that lists all 15 tracks but despite hacking away for almost an hour, I can't persuade it to convert the files. So what *should* I be typing to make this work? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

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
