Save and synchronize personnal data : .Mac or Google account

A little comparaison between Google and Apple account :

	dotMac	Google	My Choice
Price	$99	$75	Google
Size	10 Gb	25 Gb	Google
Contact Integation	Perfect	None	Apple
Image Publication	iPhoto	Picassa	Google
File Storage	iDisk	Not yet?	Apple
Calendar Integation	None	Only web to iCal	Google

For Google :

+ Price

+ Web Calendar

dot Mac Account :

+ The best integration with MacOS …

+ Contact synchronisation with web interface

– iCal not on web

A very fast Site-Search engine : Sphinx (with Python API:-)

I found this search engine very, very fast…I try to run my own benchmarks and the results are very impressive !

Sphinx is a full text search engine for database content but you can also read XML text files. It was specially designed to integrate well with SQL databases and scripting languages. For very large datasets you can have distributed indices and searching.

Features :

– high indexing speed (upto 10 MB/sec on modern CPUs)

– high search speed (avg query is under 0.1 sec on 2-4 GB text collections)

– high scalability (upto 100 GB of text)

– supports distributed searching

– supports MySQL natively (MyISAM and InnoDB tables are both supported)

– supports phrase searching

– supports phrase proximity ranking, providing good relevance

– supports English and Russian stemming

– supports any number of document fields

– supports document groups

– supports stopwords

– supports different search modes (“match all”, “match phrase”)

– generic XML interface which grealy simplifies custom integration

– pure-PHP (ie. NO module compiling etc) searchd client API- A set of API libraries for popular Web scripting languages (PHP, Python, Perl, and Ruby are bundled)

I’m planning to use it more extensively for indexing and searching … For me it’s end of Lucene (in my products)…

Thanks Andrew Aksyonoff ( For information he began developing Sphinx in 2001)

Writing underscore (LOW LINE) on MacBook Keyboard

I search this key because my MacBook’s Keyboard isn’t obvious.

On MacBook’s keyboard it shares a key with the hyphen on the top row ( to the right of the 0 key). On my older pc keyboard the underscore is in bottom of the 8 key…

So this post is only for memo..

Another good Video clip: Air – Electronic Performers

Just because I like the video clip : – )

And the music too ! It’s a french techno music, Congratulations and thanks for this great job 🙂

It’s also a sort of “information processing”…

Uncompress / decompress / unpacking a tar.gz file

You can decompress files with the extension .tar.gz (unpack a tarball) using the gunzip or tar commands as follows:

	gunzip file.tar.gz

	OR

	tar xzvf file.tar.gz

If you want more information about : tar file format

I love this song: AaRON – U Turn(lili)

It’s very useful but not present on my Mac Book Keyboard….
