In application/libraries/REST_Controller.php find the following function:

protected function _check_login($username = '', $password = NULL)</pre>
 {
 if (empty($username))
 {
 return FALSE;
 }

 $auth_source = strtolower($this->config->item('auth_source'));

if ($auth_source == 'ldap')
 {
 log_message('debug', 'performing LDAP authentication for $username');
 return $this->_perform_ldap_auth($username, $password);
 }

$valid_logins = & $this->config->item('rest_valid_logins');

if ( ! array_key_exists($username, $valid_logins))
 {
 return FALSE;
 }

// If actually NULL (not empty string) then do not check it
 if ($password !== NULL AND $valid_logins[$username] != $password)
 {
 return FALSE;
 }
 return TRUE;
 }

And replace it with the following:

protected function _check_login($username = '', $password = NULL)</pre>
{
 if (empty($username))
 {
 return FALSE;
 }
 return $this->tank_auth->login($username, $password, FALSE, FALSE, TRUE);
 }

If you are not auto loading the tank auth library, be sure to do that in your constructor as well.

Whilst doing a bit of research into this, I came across this discussion on the bootstrap github page:

https://github.com/twitter/bootstrap/issues/424

There are a few additions you can include in the bootstrap CSS file to easily enable support for multi level dropdowns. The CSS is shown below:

.nav li.dropdown ul.dropdown-menu li:HOVER ul

{

display:block;

position:absolute;

left:100%;

-webkit-border-radius: 3px;

-moz-border-radius: 3px;

border-radius: 3px;

}

 

.nav li.dropdown ul.dropdown-menu ul

{

display: none;

float:right;

position: relative;

top: auto;

margin-top: -30px;

}

 

.nav li.dropdown ul.dropdown-menu .dropdown-menu::before

{

content: '';

display: inline-block;

border-top: 7px solid transparent;

border-bottom: 7px solid transparent;

border-right:7px solid #CCC;

border-right-color: rgba(0, 0, 0, 0.2);

position: absolute;

top: 9px;

left: -14px;

}

 

.nav li.dropdown ul.dropdown-menu .dropdown-menu::after

{

content: '';

display: inline-block;

border-top: 6px solid transparent;

border-bottom: 6px solid transparent;

border-right:6px solid white;

position: absolute;

top: 10px;

left: -12px;

}

Once this has been added you can easily place an extra level of dropdown in your HTML like so:

<ul class="nav">

<li class="active"><a href="#">Regular link</a></li>

<li class="dropdown" id="menu1">

<a class="dropdown-toggle" data-toggle="dropdown" href="#menu1">

Dropdown

<b class="caret"></b>

</a>

<ul class="dropdown-menu">

<li><a href="#">Action</a></li>

<li><a href="#">Another action</a></li>

<li><a href="#">Something else here</a></li>

<li class="divider"></li>

<li>

<a href="#">Separated link</a>

<ul class="dropdown-menu">

<li><a href="#">Sub Menu</a></li>

</ul>

</li>

</ul>

</li>

</ul>

&nbsp;

Thanks to all the guys on that thread who posted solutions to this. It has come in very useful.

At first I thought it was the monitor itself so swapped it for another one but as it turns out it was s daemon called ‘upowerd’ causing the problem. Thanks to the guys over at #radeon on freenode for pointing this out.

upowerd polls the monitor every 30 seconds and on some VGA setups this causes the monitor to briefly switch off and then on again. Killing the upowerd process stops the monitor doing so but within a couple of minutes the process starts back up again. In the end I just moved the binary somewhere else so it couldn’t be started and it has cured the problem. From what I can tell upowerd not running isn’t a huge problem but time will tell if it comes back to bite me in the future…

** EDIT – Well there is a problem with not running upowerd it would seem. The PC won’t go into standby without it running. I have decided to look into sorting this out properly but in the short term I am just running upowerd before I put the machine into standby and killing it when I switch it back on. This seems to do the job OK but not an ideal long term solution…

If you attempt this with some versions of XEmacs the open file dialog will not appear and you will see the following error:

window height 0 too small (after splitting)

There is a workaround for this bug (which hopefully will be fixed in an upcoming XEmacs release).

First you have to locate the file minibuf.elc. In Ubuntu 10.10 (with XEmacs version 21.4.22) this file is located in :

/usr/share/xemacs-21.4.22/lisp/minibuf.elc

Open this file and within it you need to search for the following string:

split-window frame-height 3

Replace the 3 in that line with a 5. After this open your init.el file. This is usually in ~/.xemacs – In this file add the following line:

(load-library "minibuf.elc")

Et Voila! After you have done all this you should be able to get the open file dialog to appear.

#!/bin/bash

for file in `ls *.pdf`
do
   convert $file `echo $file | sed 's/\.pdf$/\.jpg/'`
done

A quick google about brought up this bug:

Launchpad Bug Report

The solution to the problem is in comment #8 on there. Basically you need to use the following boot option to get the display working correctly

xforcevesa i915.modeset=0
Just stick this in at the bootloader and it should be fine. When Ubuntu is fully installed just put the same line into /etc/default/grub to make the change permanent.

SimpleImage.php

A quick example usage to show how simple it is…

include('SimpleImage.php');
$image = new SimpleImage();
$image->load('picture.jpg');
$image->resize(250,400);
$image->save('picture2.jpg');
The last time I had to do some image resizing with PHP was a number of years ago and I seem to remember it being a lot more complicated than this.

Thanks to White Hat Web Design for making this little class and making it available.

To be able to configure your tunnels IPv4 end point (ie the IP address of the router on your home network) the IP address you are setting needs to be pingable. First this was a bit of a pain as I needed to set up my BT Router so put the Linksys in the DMZ. After messing with that for a bit it was all working.

Despite everything being set up correctly I still wasn’t able to ping my home IP. After a bit of digging on the net I discovered that OpenWRT blocks all ICMP traffic by default which is a bit of a pain in the arse really.

Anyway, here is the config change that you need to make to /etc/config/firewall to enable all ICMP traffic through the firewall:

config rule

option proto ICMP
option target ACCEPT
