			<content:encoded><![CDATA[<p>For security reasons and for easier maintenance, network administrators usually lock your computer quite a lot. But what makes the job easier for them (ppl can&#8217;t get viruses easily nor mess up with the settings and break the configuration) makes it harder for you: you can&#8217;t install this software you need, you&#8217;re stuck on <acronym title="Microsoft Internet Explorer 6">MSIE 6</acronym> while you&#8217;d like to use Opera 10.x or Firefox 3.6pre, sometimes you can&#8217;t even visit some sites, and anyway your whole traffic is being logged. Here are some tips and solutions that may work to make your life easier:</p>
<h3>Want to install a specific piece of software?</h3>
<p>Think portable. More and more software is available in a portable version. Notably, <a href="http://portableapps.com/" rel="nofollow">PortableApps.com</a> has an ever growing collection of them (and they&#8217;re most if not all <a href="http://www.gnu.org/philosophy/free-sw.html">free as in free speech</a>). With some portable software and in some environments, you&#8217;ll want to rename setup files to some other name not containing the word &#8220;setup&#8221; (yes, there are some administrators who think they can prevent you from installing stuff by blocking executables named &#8220;setup&#8221; or &#8220;install&#8221;). Some software isn&#8217;t distributed in a portable version but can still be made portable: for instance <a href="http://www.r-project.org/">R</a> can&#8217;t be found as a portable package, but if you install it at home and copy/paste the folder where you installed it, you&#8217;ll have a perfectly working R for your USB stick&#8230; or for work.</p>
<h3>Need this cool Visio/[insert any commercial software there], but it costs money and needs a long request that may never succeed anyway?</h3>
<p>Think <a href="http://www.osalt.com/">Open Source Alternatives</a>. For instance Osalt.com is a directory of commercial and open source software, which for every piece of commercial software lists the commercial counterparts. For instance you&#8217;ll find that Microsoft Visio can be replaced by Dia, StarUML or even&#8230; OpenOffice Draw. And the great thing is, most of these exist as portable apps (see previous chapter).</p>
<h3>Want to keep your privacy when browsing around the internet?</h3>
<p>This part is a bit more complicated. First you need a proxy with an encrypted connection. For this you can set up OpenSSH at home on Windows or on Linux, or for a faster connection on a dedicated server. Anyway we won&#8217;t detail this part (for instance on Ubuntu server you should have everything already properly set up right after installation) and we&#8217;ll assume you managed to get this proxy with SSH support. Now we&#8217;ll see how to connect to it, from Windows:</p>
<ol>
<li>Get <a href="http://www.chiark.greenend.org.uk/~sgtatham/putty/">PuTTY</a></li>
<li>Launch it using a command like <code>putty -D 9990 -P 22 150.127.5.5</code> where 150.127.5.5 is the IP of your proxy (it can also be a domain name resolving to this IP) and 22 is the port on which OpenSSH is listening on your proxy. You should create a batch file with this command to make it faster for the next times.</li>
<li>Now configure your browser (e.g. <a href="http://www.megaupload.com/?d=XB0UCJDA">Firefox portable edition</a>) to connect through socks proxy 127.0.0.1:9990</li>
<li>If using Firefox, in about:config configure <strong>network.proxy.socks_remote_dns</strong> to true (the default, false, means that any domain name you query will be sent unencrypted over your company&#8217;s network&#8230;)</li>
<li>Everything should be set up and working now, but you may want to <a href="http://www.whatismyip.com/">check your IP</a> to be sure you&#8217;re going through your proxy.</li>
</ol>
<p>We&#8217;ll see in a later post how to configure PuTTY in the case where your company forces you to go through an HTTP proxy. For the moment, that will be all, folks.</p>
<h3>&#8230; but, remember</h3>
<p>You&#8217;ll still be vulnerable to key or screen loggers, and also your network admin will be able to see that you&#8217;re surfing through SSH, even though he won&#8217;t see what&#8217;s inside it. So stay reasonable!</p>

			<content:encoded><![CDATA[<p>About a week ago, I received an e-mail from Google saying that as a Google Analytics user I might be interested in trying out Adwords, this with a nice 100&euro; coupon (on a side note, this e-mail was written in French while I&#8217;ve always configured my browser and every Google service to display in English&#8230; freaking incompetent localizers&#8230;). Remembering the fact that most Adwords coupons I ever saw were rather worth around 50$, I thought this would be a nice opportunity to try to boost a bit my not-yet-famous <a href="http://www.wiki4games.com/">Wiki4Games</a>.<br />
So here I go. First catch: you need to make a payment of 5&euro; to activate your account (the coupon can&#8217;t be used in this purpose). Ok, then I&#8217;ll pay 5&euro; and get 105&euro; of advertising credits. It&#8217;s not free anymore, but it&#8217;s still looking good.<br />
Second catch: the minimum payment you can make is 10&euro;&#8230; I start hesitating, but after all, it still looks like a good deal and if it&#8217;s not, at least I&#8217;ll have something to post here <img src='http://notepad.patheticcockroach.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>
<p>=> First summary: I got an ad e-mail saying I&#8217;d get 100&euro; of free advertising without anything to pay (the e-mail clearly stated that the 5&euro; activation fee could be deducted from the 100&euro; offered), in reality I got 110&euro; of advertising credits but paid them 10&euro;</p>
<p>Here goes the campaign, not too hard to set up (the &#8220;easy&#8221; mode is what made me waste a lot of time at the beginning, and now that I switched to the &#8220;Standard Edition&#8221; &#8211; ie the edition not for retards &#8211; I have a nice undismissable sticky polluting my Account Snapshop page &#8211; see screenshot), and running smooth at start: over 50,000 views within the first 12 hours.</p>
<div style="text-align:center;"><a href="http://img.patheticcockroach.com/01/adwords_noob_sticky.png"><img src="http://img.patheticcockroach.com/01/adwords_noob_sticky.png" alt="stupid sticky in case you're retarded" width="450" height="312"/></a></div>
<p>Something that struck me, though, is the very high default <acronym title="Cost Per Click">CPC</acronym>: if you use the noob-mode campaign set up, it&#8217;s around 0.69&euro; (which, as of today, is pretty close to 1$). But even though I lowered it to 0.10&euro;, the ads displayed fast&#8230; at first&#8230;</p>
<p>I also chose some keywords to display the ads on some relevant Google Search result pages. Wiki4Games being a video game wiki, I notably chose &#8220;video game wiki&#8221; and &#8220;video games wiki&#8221; as keywords. Our current position to these keywords is around 4-5 (see screenshot), over more than 22 millions other results.</p>
<div style="text-align:center;"><a href="http://img.patheticcockroach.com/01/adwords_w4g_keyword_position.png"><img src="http://img.patheticcockroach.com/01/adwords_w4g_keyword_position.png" alt="Wiki4Games 4th website on the video games wiki keyword" width="450" height="557"/></a></div>
<p>Adwords gently complained that my max CPC bid was a bit too low which would result in a bad placement and fewer impressions, still I got over 75,000 during the first day, then 50,000, then a bit less, and then it fell to almost nothing &#8211; less than 900 today (with no impression on Google Search, only impressions on the Adsense network). And the worst part is, Adwords claim my keywords are irrelevant. More precisely, they <em>became</em> irrelevant: during the first days, my keywords were rated 7/10 (one of them was even 10/10). Since 2 days, they are rated 2/10, that&#8217;s right, my website is in the top 5 over 22,000,000 results for this keyword yet the keyword is irrelevant!</p>
<div style="text-align:center;"><a href="http://img.patheticcockroach.com/01/adwords_w4g_keyword_rating.png"><img src="http://img.patheticcockroach.com/01/adwords_w4g_keyword_rating.png" alt="keyword with a bad rating" width="450" height="382"/></a></div>
<p>So is Google irrelevant or am I too cheap for them? I guess I&#8217;ll have to increase my CPC bids and see if my relevance increases too&#8230; I&#8217;ll then see if Google violates the very web neutrality they made so much ado about, or if Adwords just sucks at keywords&#8230;</p>
<p>PS: and I forgot to mention, my second ad (pointing to <a href="http://www.wiki4games.com/index.php?title=Dune">a page about Dune</a>) has been pending for review for 5 days, and counting&#8230;</p>
<p>Update on July 31: Dune ad still pending review! (a month and a half after submission!)<br />
Update on Aug 29: The Dune ad was finally approved, at some unknown point in August</p>
