Microsoft Rebrands Live Search as “Bing”

Thursday, May 28th, 2009

Microsoft is upping their strategies to overcome the everest of search engines: Google. Unfortunately for the software giant, they had to post loses in the first quarter compared to Google’s sales of $4.7 billion. To learn more about Microsoft’s new search engine, check out their promo: www.decisionengine.com

While it definitely has some useful tools, we still have not seen anything that matches the sleek simplicity of the google engine.

Google attacked by conficker?

Thursday, May 14th, 2009

According to this article Google may be suffering from DDoS attacks from the conficker virus. Portions of the web giant have been inaccessible throughout the day.

While much of this is speculation, it does strike a chord for computer security. With cloud-computing and information indexing creating a more centralized internet…will future attacks have the capacity to bring down entire chunks of the internet?

Google’s nofollow tag failure

Thursday, May 14th, 2009

An interesting article on blog-spam countermeasures — Google’s embarrassing mistake. Quote:

I think it’s time we all agreed that the ‘nofollow’ tag has been a complete failure.

For those of you new to the concept, nofollow is a tag that blogs can add to hyperlinks in blog comments. The tag tells Google not to use that link in calculating the PageRank for the linked site. [...]

Since its enthusiastic adoption a year and a half ago, by Google, Six Apart, Wordpress, and of course the eminent Dave Winer, I think we can all agree that nofollow has done — nothing. Comment spam? Thicker than ever. It’s had absolutely no effect on the volume of spam. That’s probably because comment spammers don’t give a crap, because the marginal cost of spamming is so low. Also, nofollow-tagged links are still links, which means that humans can still click on them — and if humans can click, there’s a chance somebody might visit the linked sites after all.

Spammers have it in their heads now that weblog comments are a vector to exploit. They don’t look at individual results and tweak their software to stop bothering individuals. They write generic software that works with millions of sites and goes after them en masse. So you would end up with just as much spam, it would just be displayed with unlinked URLs.

Spammers don’t read blogs; they just write to them.

I still think he was spot on.

However, one part of the ‘Google’s embarrassing mistake’ article is a red herring — I think the chilling effect on “nonspam links” is not to be worried about; as Jeremy Zawodny said, life’s too short to worry about dropping links purely in the hopes of giving yourself Page Rank. I don’t know if I really want links that people are leaving purely for that reason. ;)

In fact, I wouldn’t be surprised to hear that Google’s crawler starts treating “nofollow” links as mildly non-spammy in a future revision, due to their wide use in wikis, blogs etc.

To be honest, though — I don’t see the problem of blog-spam much anymore.

[Weblog] comment spam should be a lot easier to deal with than SMTP spam. … With weblog comments, you control the protocol entirely, whereas with SMTP you’re stuck with an existing protocol and very little “wiggle room”.

I’ve instituted a very simple check stolen from Jeremy Zawodny. I simply include a form field which asks the comment poster for my first name, and if they fail to supply that, the comment is dropped. In addition, I’ve removed the form fields to post directly, requiring that all comments are previewed; this has the nice bonus of increasing comment quality, too.

Those are the only antispam measures I’m using there, and as a result of those two I get about 1 successful spam posted per week, which is a one-click moderation task in my email. That’s it.

The key is to not use the same measures as everyone else — if every weblog has a different set of protocols, with different form fields asking different simple questions, the only spammers that can beat that are the ones that write custom code for your site — or use human operators sitting down to an IE window.

Trackbacks, however — turn that off. The protocol was designed poorly, with insufficient thought given to its abuse potential; there’s no point keeping it around, now that it’s a spam vector.

Finally, a “perfect” solution to blog spam, while allowing comments, is unachievable. There will always be one guy who’s going to sit down at a real web browser to hand-type a comment extolling the virtues of some product or another. The goal is to get it to a level where you get one of those per week, and it’s a one-click operation to discard them.
