			<content:encoded><![CDATA[<p>I&#8217;m following most web sites with <a href="http://reader.google.com/">Google Reader</a> these days.  With some sites I&#8217;ve noticed that images don&#8217;t show up in the reader interface.  I figured this would be because the site is attempting to protect against <a href="http://en.wikipedia.org/wiki/Inline_linking">hot-linking</a> to its resources &#8212; and it seems I was right.</p>

<p>The quick fix with <a href="http://www.mozilla.com/">Firefox</a> is to disable sending referer-information for inlined images.  You can do this in <a href="about:config">about:config</a> by changing the value of <a href="http://kb.mozillazine.org/Network.http.sendRefererHeader">network.http.sendRefererHeader</a> to 1.</p>

<p>While there, I also changed <a href="http://kb.mozillazine.org/Network.http.sendSecureXSiteReferrer">network.http.sendSecureXSiteReferrer</a> to false.  This prevents referer-information from being sent between different secure sites.</p>]]></content:encoded>

			<content:encoded><![CDATA[<p>I never seem to be able to remember this, and somehow I end up with new Windows installations without this change:</p>

<blockquote>
<pre><code>netsh interface ipv6 set privacy state=disable
</code></pre>
</blockquote>

<p>This will disable temporary IPv6 addresses.  These are especially nasty on desktop systems, where the address will expire from under you.  If you find yourself having to restart your <acronym title="Secure Shell (encrypted alternative to TELNET and FTP)">SSH</acronym> terminal connections every 14 hours to 6 days, this is why (as far as I can tell).</p>

<p>I really don&#8217;t buy the privacy aspect of generating random IP addresses.  If you worry about eavesdropping, encrypt your traffic.  If you worry about someone tracking your traffic patterns, stop browsing those questionable sites.  :)</p>]]></content:encoded>

			<content:encoded><![CDATA[<p>I&#8217;ve been reading about the new passport requirements the USA is making of visa-less visitors, and now there was <a href="http://www.helsinginsanomat.fi/english/article/1101979128144">an article about it in Hesari</a>.  I guess I should plan to return for a visit before my passport expires in 2007.</p>

<p>Unless they implement <a href="http://www.iwar.org.uk/news-archive/2005/01-25.htm">the plan to issue RFID tags to all foreigners</a> for automatic tracking.  Traveling is supposed to be something you do for fun, and I don&#8217;t consider wearing an electronic ankle bracelet much fun.  I guess plan B is to meet all my American friends in Montreal or Vancouver.</p>]]></content:encoded>

			<content:encoded><![CDATA[<p>Given that I&#8217;ve successfully avoided spam by using <em>me at example dot com</em> as an &#8220;obfuscation&#8221; method for email addresses, I&#8217;m not surprised by the findings that <a href="http://philringnalda.com/blog/2005/03/spammers_are_lazy.php">spammers are lazy</a>.  But it is still interesting to read about good proof through a real test, and I&#8217;d hazard a guess that using hex entities may be a longer-lasting method.</p>

<p>I&#8217;d consider replacing the JavaScript I currently use, if it weren&#8217;t for the fact that people already seem to be able to find my email address just fine.  Actually, Phil&#8217;s article would seem to support the case that disabling JavaScript is rare.  He only got a couple of actual messages to the non-JavaScript address.  I guess that&#8217;s good news for me.</p>]]></content:encoded>

			<content:encoded><![CDATA[<p>Ei ole ollenkaan uusi ajatus, että tuleva työnantaja kirjoittaa työnhakijan nimen Googleen ja muodostaa sitä kautta palkkaamispäätökseen vaikuttavia mielipiteitä.  Kuitenkin useimmilla ihmisillä on selvä raja yksityisen elämän ja työelämän välillä.  Yksityiselämän asiat eivät kuulu työpaikalle, ja työelämän asioitakin tavallisesti pyritään pitämään poissa kotielämästä.  Internetissä tämä raja helposti hämärtyy &#8212; on liian helppoa nähdä kumpikin elämä samalla kertaa hakukoneiden avulla.
<span id="more-127"></span></p>

<p>Harrastuksista, mielenkiinnon kohteista ja maailmanmenosta yleensä olisi kiva voida kirjoittaa vapaasti, miettimättä sitä, kenen kanssa asiasta on samaa mieltä.  Kaveripiirissä keskusteltaessa näin voikin tehdä.  Yleensä harrastuslistoilla kirjoittaa samasta asioista kiinnostuneiden kanssa.  Useimmat blogit taas on suunnattu kavereille &#8212; tai en ainakaan tunne ketään, joka olisi aloittanut kirjoittamaan blogia tavoitellakseen julkisuutta.  Viestejä kirjoittaessa tulee automaattisesti otettua huomioon kohderyhmä, ja teksti voi sisältää viittauksia foorumin yhteiseen historiaan, jonka kaikki lukijat pääsääntöisesti ymmärtävät.</p>

<p>Hakukoneen tuloslistasta poimittuna yksittäisen viestin sisältö on helppo tulkita väärin.  Harva lukija viettänee aikaa lukemalla saman foorumin muuta sisältöä.  Ongelmaksi voivat muodostua myös työhön täysin liittymättömät mielipiteet: työpaikkahaastattelussa ne tuskin tulevat esiin, mutta Internetin palstoille jätetyt kommentit voivat helposti nousta hakukoneen palauttamien linkkien kärkeen.</p>

<p>Parasta ehkä olisi kirjoittaa useammassa paikassa eri asioista.  Ehkä se rajoittaisi hakukoneiden kykyjä jonkin verran.</p>]]></content:encoded>

			<content:encoded><![CDATA[<p>I have new versions of <a href="http://www.mozilla.org/products/firefox/">Firefox</a> running on my computers, and I was busy adding <em>block images</em> rules on each one.  I thought this was less than ideal, so I decided to give <a href="http://www.privoxy.org/">Privoxy</a> a new try.  I saw that a new version is out, so I updated <a href="ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/www/privoxy/README.html">the package</a> as well.  Apart from getting more up-to-date filters, there&#8217;s a memory leak fix and I could also enable threads for parallel request handling.</p>]]></content:encoded>
