Slashdot | Yahoo Releases Open Source Hadoop Distribution

Yahoo has been a vociferous Apache Hadoop user and supporter for several years now, and uses it extensively within its Search technologies. Hadoop has been gaining popularity in the Cloud Computing space, with companies like the NYTimes converting 4TB and 11 million articles to PDFs in under 24 hours using Hadoop and EC2 in late 2007. Hadoop has been made available in Amazon’s cloud and Yahoo has now released its own Hadoop version.

Shopping in the IT

Oracle buys BEA and Sun buys MySql.

In reply,Migrosoft is hungry and is watching Yahoo :-)

<joking> 

Any bets on the next money-based-news?

I'm going for

  • Oracle buys Sun: "We need more hardware to run Oracle and WebLogic together! "
  • Google buys Oracle: "We have *even* more hardware…come on!"
  • Apple buys Google: "So nice LOGO", retrodating a bunch of stock options, I suppose.
  • Microsoft buys Apple ("So annoied their are more cool then us!") and shut down all them all so you will end up using their search engine, I hope.

</joking> 

Surely Oracle needed a good application server to push its db.
Sun move seems  a bit strange in my humble opinion: anyway the big competitors in standard dominance (Sun,Oracle,MS) now have all the same stuff: broad used databases and application servers.

Even Apple has acquired FileMaker, pushing it with the "Bento" single-user-oriented db. 

Google has a different approach and a bit different market scope, so do not enter in the plan drafted here.

Sun move is very strange because MySql is not an "enterprise" stuff as in the Sun-way-of-life; normally Sun wants big software which need big computers, to buy at Sun Shop.

MySql should be acquired by Microsoft because of its very light footprint: but it sounds too much open source stuff for this move.

 

 

 

 

Celeste

Celeste

Celeste is a mail reading and organizing program. The name “Celeste” is a reference to an earlier mail reader named Baba, which was written at Xerox PARC by Steve Putz and John Maloney.

Nowadays, Celeste is maintained by Giovanni Giorgi (me).

Latest Feature

A new revision is planned for the end of September 2006, and code name will be “Sonic”.
Sonic will include a smart mailing-list filter and a better “leave message on server” option.
I implemented years ago an auto-filtering system in AppleScript.
The filtering engine used the
RFC2369 and some other tricks to detect yahoo mailing list.
Sonic will have also an auto-filter for google mailing list too.

The leave message on server option is quite bad now. It creates a lot
of duplicated messages.
The new implementation will avoid dowloading twice a message, using
a mix of messageId and timestamp to detect duplicated messages.

Version policy

I have found a misleading versions for celeste.
Celeste uses a “versionString” to mark a version in every sent email.
versionString labelled something like
2.currentChangeset.

As far as I started mantaining Celeste, we used a lower version (for example 1.23).

To avoid confusion I have started to renmbering all the stuff starting from revision 3.0.

Anyway, the version name is the first thing you should consider. I plan to do very few releases.

Celeste Auto Filter Capability (BETA)

Some busy users subscribe and unsubscribe to a lot of mailing list.
Managing them with filter is possibile, but can be done only by hand.
Worst, email programs tend to be very slow if a single folder is full of stuff,
and this can be true for Celeste too.

The Celeste Auto Filter option will enable a smart archiving system,
packing the email in seasons.
For instance “2006Q1-squeak-dev” will contain all the emails of squeak-dev of the first three month of 2006 (=the first quarter).

The Auto Filter will understand YahooGroups, Mailman and GoogleGroups mailing list, auto-dispatching them to the right category.
The filter will be enabled by default.
