Implementing spam protection in Wiki engines

Posted 2 May 2011 at 08:26 UTC (updated 2 May 2011 at 11:35 UTC) by audriusa

Spam is really a problem in many Wiki communities, often forcing at least temporary to restrict editing rights. Most of the recent attempts to find a solution focus around captchas and spam lists. Captchas may be efficient to some extent; the problem is that to make them unreadable for bots, they must be twisted enough to become also difficult for humans to read. Lists seem less and less efficient, often accumulating thousands of entries and still leaving enough gaps for spammers. Spammers frequently use the Wiki search box to check if there is already some spam on the site - this shows that Wiki may be purely maintained and they can add more. Hence it may make sense to implement the delayed indexing but it also delays indexing of legitimate content. Blocking IP addresses is also no longer useful due DHCP.

One of the solutions may be to use combined protection rather than relying on some single "killer" approach. The rationale is to make spammer to invest more and more work into building the spam bot. Requiring a complex bot does not make the attack impossible but may statistically eliminate significant percent of spammers that are not willing to invest enough resources.

Triolet

Posted 7 Apr 2011 at 19:28 UTC (updated 8 Apr 2011 at 21:48 UTC) by badvogato

I came up with this triolet to add my two cents to a Chinese physicist and poet's view on Oxford debate 'Poetry is beautiful but Science is what matters' :

Verse and song gave birth to thee
fearful mechanical and scientific device
Love's but a dance
of verse and song sublime to thee
A whisper, a glance, this little death --
"Shall we twirl down in Elysian Fields ?"
Verse and song gave birth to thee
fearful mechanical and scientific device

Piracy and Free Software

Posted 11 Oct 2010 at 16:51 UTC by mako

Over the last few years, many advocates of access to information have gathered and organized under the banner of piracy. Should FLOSS and free culture advocates embrace advocates of piracy as comrades in arms or condemn them? Must we choose between being either with the pirates or against them? I believe that, unintuitively, if we take a strong principled position in favor of information freedom and distinguish between principles and tactics, a more nuanced "middle ground" response to piracy is possible. On free culture and free software's terms, we can suggest that piracy is not ethically wrong, but that it is an shortsighted and unwise way to try to promote sharing that we should not support.

The behavioral economics of free software

Posted 25 May 2010 at 19:36 UTC (updated 26 May 2010 at 13:26 UTC) by mdz

People who use and promote free software cite various reasons for their choice, but do those reasons tell the whole story? If, as a community, we want free software to continue to grow in popularity, especially in the mainstream, we should understand better the true reasons for choosing it—especially our own.

This is a repost of an article originally posted at http://mdzlog.alcor.net/2010/05/25/the-behavioral-economics-of-free- software/

Proposal to extend DNS with Peer to Peer server-independence

Posted 28 Jan 2010 at 20:12 UTC by lkcl

Google and others have just proposed that DNS be extended. If DNS is going to be changed in such a minor way, why not do something much more useful and interesting, which has a fully-functioning implementation already in prevalent use for over fifteen years on millions of free software systems? Why not make the DNS protocol a true server-independent peer-to-peer Naming Service? In combination with the modern DNSSEC extensions, many of the complaints associated with the current peer-to-peer free software implementation would vanish.
