Sõltub sellest, kui privaatseks keegi oma külastatud veebilehtede nimekirja peab muidugi, aga javascriptiga on võimalik edukalt tuvastada, millistel veebilehtedel sa eelnevalt käinud oled. Hea näide sellest on Start Panicking! lehekülg. See ei tuvasta küll kõiki lehti, vaid kontrollib külastusi konkreetse nimekirja vastu. Küllalt pika nimekirja korral saab aga üsna palju teada, näiteks on nimekirjas 41 .ee lehekülge.

Nipp on iseenesest lihtne. Veebilehe css’is määratakse ära, mis värviga kuvatakse külastatud lehtedele suunavaid linke ja javascripti abil siis tuvastatakse, mis värviga linki kuvatakse. Selle konkreetse augu vältimiseks saab Firefoxis sättida layout.css.visited_links_enabled väärtuseks false, misjärel külastatud linke enam ei eristata või siis keelata ära javascript mõne mugava lisa abil. Vaikimisi on selle väärtus aga true ning javascriptki on lubatud.

See on muidugi vaid üks näide sellest, mida javascriptil teha on võimalik ja juba üsna ammu teada.

Dear Website Owner|

Our company is on the first page when you search on Google for our primary search term \"SEO Company.\" We would like to do the same for your web site so you can come up for your main keywords as well?

Please reply and I would be happy to send you a proposal.

I’ve got some questions:

1. Did he bother to look at the site? It is a non-profit site and therefore unlikely to be optimised for #1 ranking on Google.
2. It’s not hard to be first for “SEO company”. They’re not on the first page if you try “SEO” and even if first page for that term refers some general pages like Wikipedia, it does have Seoconsult ranking 4th. If I were to type in “titmice fanlisting” instead of “titmice” it comes up first too. And I hardly believe most people looking for information about titmice are interested in a fanlisting, more often they expect to find general information and Wikipedia is a great resource for that.
3. Why is there a pipe character after “Owner”?

I started missing Linux on desktop, so due to 256MB memory went with Xubuntu couple of days ago. I’m going to skip issues with network card and kernels in this post though.
The case is that when I choose to switch user, then.. well it switches just fine, that is it gives login screen for another user. But, when another user logs out, login screen won’t appear. Can you guess what happens instead? My desktop is shown. Fully functional. No need to authenticate at all. Even if I have thunar (xfce’s file browser) opened with root privileges. Here goes the famous linux security.. well it’s an exception to that, I guess. Like the one with ssh keys some time ago.
Any way, there’s a thread on ubuntuforums.org about a similar issue, so I thought I’d reply. Except that I can’t. At first I couldn’t log in, then when I got in, I get logged out every time I try to post! No, my cookie-handling is fine. Turning off firewall, clearing browser cache and switching browser to a different one as some usual things to try when experiencing something odd in networking, don’t help.
Interestingly traceroute to forums never completes. It goes on forever with *** after gw0-0-gr.canonical.com [91.189.88.10] hop. With my connection, that is. Traceroute using another connection shows that this hop should be right before the destination.
Might be a faulty ip perhaps? I did get one that was in ahbl blacklist as an open proxy some time ago and needed to acquire new one to have access to mozilla irc channels. Disconnecting modem power didn’t get me new ip this time and I really don’t feel like dealing with my isp’s tech support. So I hope it clears by tomorrow all by itself (well maybe disconnecting modem for night). But if it doesn’t, I still have to deal with it, ugh. I don’t know too much about networking, certainly not about networking issues. Fingers crossed here.

Have you tried Google search hacker language? I just did. It’s funny.

I don’t know perhaps I’m way too naive but I would have thought that a site as popular as this one cares more about security. But apparently someone who was trying to retrieve their login information has typed in my username which results in two emails to my address both containing my current password. I hope they can remember their own username as well in the end .
