For some stuff that couldn’t bare the daylight I needed some anonymity. Tor (The Union Router) is really suited for this purpose:

“Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.”

Here’s some more information about Tor:

Installation of Tor (for Firefox) isn’t to hard:

  • First we have to add the repository:
    sudo apt-add-repository ppa:sevenmachines/tor
    
    Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.ubuntu.com --recv 454FEDB228E1455D687C9CBE35DA01C261E46227
    gpg: opvragen sleutel 61E46227 van hkp sleutelserver keyserver.ubuntu.com
    gpg: sleutel 61E46227: publieke sleutel ‚ÄúLaunchpad Default PPA‚ÄĚ geimporteerd
    gpg: Totaal aantal verwerkt: 1
    gpg:               Geimporteerd: 1  (RSA: 1)
    
  • After that we have to update apt and install the needed packages:
    sudo apt-get update
    sudo apt-get install tor polipo
  • Next, we have to configure polipo:
    cd /etc/polipo/
    mv config config.ori
    wget https://svn.torproject.org/svn/torbrowser/trunk/build-scripts/config/polipo.conf
    mv polipo.conf config
    /etc/init.d/polipo restart
  • And finally we have to install the Torbutton Firefox plugin
    Torbutton

IE6 denial

IE6 denial

A problem all web designers know is making a website work in Internet Explorer 6. IE 6 is not standards conforming. So even when you, as a designer, stick to the W3C rules there’s quite a chance your website won’t render as it should. A few big websites (i.e. Youtube, Apple’s MobileMe) already banned IE6 and even Javascript guru Douglas Crockford has called for a global IE6 boycott. Although the market share is rapidly declining, quite a large portion still seems to be using it; especially in Asia and Africa (+/- 21%).

IE6 Percentage

IE6 Percentage

Why? IE6 was released in 2001, and even failed to properly support the CSS 1.0 standard from 1996…

IE6 Why?

IE6 Why?

We have to stop this oldie hold us back and make the Internet a better place ūüôā

Free the web suggests:

  • make sure your browser is up to date
  • help others to get up to date
  • if you are a web designer, stop supporting IE6
  • spread the word: Boycott IE6

Ajaxian follows a more aggressive approach: amelie()

I would suggest we all just copy and paste the following code onto your site:

<!--&#91;if lt IE 7&#93;>
<div style='border: 1px solid #F7941D; background: #FEEFDA; text-align: center; clear: both; height: 75px; position: relative;'>

< !&#91;endif&#93;-->

And IE6 users would get this nice notification when visiting your website(s):

Yesterday I did an upgrade from cake 1.30 to 1.31 on my Windows 2003 server. Unfortunately there was a problem with the cache files:

<a href="javascript:void(0);"><strong>Notice</strong> (8)</a>: unserialize() [<a href="http://php.net/function.unserialize">function.unserialize</a>]: Error at offset 0 of 1391 bytes [<strong>CORE\cake\libs\cache\file.php</strong>, line <strong>176</strong>]

Fortunately, finding an solution wasn’t to hard. A removed trim() seemed to be the culprit:

Txt cake/libs/file.php
<div>@@ -192,7 +192,7 @@ class File extends Object {</div>
195
<div>-    return $data;</div>
195
<div>+    return trim($data);</div>
Txt cake/tests/cases/libs/file.test.php
<div>@@ -115,7 +115,7 @@ class FileTest extends CakeTestCase {</div>
118
<div>-    $this-&gt;assertEqual($result, $expecting);</div>
118
<div>+    $this-&gt;assertEqual($result, trim($expecting));</div>
