Google's Technology Explored
RobotWisdom writes "Internetnews offers a moderately detailed peek at Google's technology. For example, they use stripped-down Red Hat on a massively redundant network, and they're starting to have success with automatic clustering of concepts, so that pages can match even if none of the words in your query actually appear on the page." Additional analysis on InformationWeek and C|Net. From the article: "As a search query comes into the system, it hits a Web server, then is split into chunks of service. One set of index servers contains the index; one set of machines contains one full index. To actually answer a query, Google has to use one complete set of servers. Since that set is replicated as a fail-safe, it also increases throughput, because if one set is busy, a new query can be routed to the next set, which drives down search time per box."
They should make a googleCluster Live CD.. ala clusterKnoppix.. ..or perhaps use more of clusterKnoppix features or openmosix..share cpu/mem..
sourceforge is begging for something like this..
Their engineer desktops have special google builds of linux which help them compile things insanely fast with g4, ie hacked p4 (Perforce).
They also have one of the best intranet sites I've seen. Lots of info and services the employees can use, apart from email.
The internal blogs really help with keeping track of projects you're not working on, and what others are doing. Their mailing lists are often usefull too, for example there's a lost and found, for sale, and biking partners list. All kinds of usefull little stuff, taking care of the people with little nice things. Lots of reading too.

They're not obligated to share unless they are planning on redistributing the software. They are perfectly free to patch their own software and use the patched versions for their servers without sharing those modifications.
The GPL does not force them to do anything unless they wish to redistribute the software.
this is a sig.
