  • Distributed key-value store for large amount of content? What would you do now if you need huge media storage for your photos or videos? You can wait for Facebook to opensource its Haystack storage but that may never happen... You can try Mogilefs but you will run soon into the same problem as if you would store files directly in file system because Mogilefs stores every object in a separate file. But here might be the solution for your problems - distributed Key-Value store which uses stable Tokyo Cabinet storage and can be accesses with generic memcached client: http://kumofs.sourceforge.net/ .

  • More about Wordpress malware... There is a nice site to check your site for possible malware - http://www.unmaskparasites.com/ , however one kind of malware will not show itself up to a "normal" user agent, I'm talking about one designed to poison Google index with advertisement. I wish Unmaskparasites had option to specify custom User-Agent for request. Until then analyze google cache for strange content using search query site:www.yourdomain.com or use wget with custom UA like this wget -U 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' http://www.yourdomain.com/ .
