For scripting they use Python.

The SE stuff is probably written in C/C++ though.

Hi,
Google uses Java for searching and a custom build database for storing
data.
All of the google servers are running on Red Hat Linux based
distribution and they also
use their own file system (not NTFS or FAT.. as we got used ...but
GFS (google file system).
For scripting they prefer Python(Gmail is on Python) as python is known
as one of the fastest.
Google uses also several thousends hard disks all over the world in
several terrabytes disks storage.XML is also on help for processing
data together with SOAP protocol.

Hmmm...There are also many other things to be mentioned on how they
work anyway...
but not enough for a forum message

Best,
Boby

Doubt it: source?

Doubt that one as well (fastest): source? I think Google picked Python for
other reasons. Some love Perl, some love Python :-D.

Hi,
Well about Java .. there is no doubt take a look here:
http://www.google.com/apis/
That's the google open source SDK (Software Developer's Kit) , about
Python maybe I should agree with you
because I am neither a Perl neither a Python specialist..I just knew
from friends Python is fast thatswhy choosen ,
my areas are C++ and ASP , for me aniway the greatest for a search
engine will be ASP.NET with several
Microsoft Foxpro databases for storing data ... but we all know
Microsoft and google are not loving each other and
Java is choosen maybe not because it's better than Perl but beacause
both of google's bosses Sergey Brin and Larry Page
were java programmers and because they recieved their first investment:
$100 000 from Sun Java.

Fraternally
Bobi

btw , Berimor - what technology are you using in
http://exactsearcher.com/? It's a nice search engine though
Currently I am making a software download search engine ... there are
already over 50 Linux distro's included in the search
available for direct download when found .. I'll send link soon

Ah, yes: The download includes Java and .NET programming examples.

So, uhm, they use .NET too?

No doubt about Google using Java here and there, but I doubt that their
SE is written in Java. That they offer an API and hand out examples in
Java/.NET doesn't say much about what they use internally.

I, for example, connect to the API using Perl :-D

about

One picks rarely a language on speed alone. Python is more formal, or at
least it conforms more with what I have been thought at the University
(notation wise, and some ideas). Perl is more lose. But speed? I think
that benchmarking several Perl and Python scripts doesn't give a clear
conclusion. Moreover, people are working on a common VM for Perl and
Python: Parrot.

my areas are C++ and ASP , for me aniway the greatest for a search
engine will be ASP.NET

based on what?

with several
Microsoft Foxpro databases for storing data ... but we all know
Microsoft and google are not loving each other

As you wrote: Google uses it's own data storage and handling stuff. This
database is optimized for what they do, and I doubt that there is any
commercial general purpose database that can outperform it, otherwise
Google would swap to that. A company that writes their own software
because they don't love another company if that other company creates a
better product is quite silly IMNSHO.

and
Java is choosen maybe not because it's better than Perl but beacause
both of google's bosses Sergey Brin and Larry Page
were java programmers and because they recieved their first
investment: $100 000 from Sun Java.

I doubt if the bosses do programming :-) I often have a good laugh if
people are angry with Bill because he designed MS Windows bad, like he
in the morning fires up his computer, and starts hacking on Vista :-D.
