    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.

    Objectsroot revamp of posts

    Hi all, dear readers (and spammers too... you delight me with your poor tatics)!
    Because my job is getting very very boring, and my private life is full of fantastic nights, I have decided to write a bunch of new articles, and stack them on objectsroot.com.

    iPhone programming

    iPhone is the brand-new Apple product which has changed the way Apple thinks. Because of iPhone, Apple strip the word "Computers" from its brand name. And because of iPods and iPhone products, Lepoard developmenet slip a bit, blurring the focus on pure technology.
    To be true, I do not beat on  the iPhone success, but the product success is at least  bright this year. And the iPod touch has also added value to the iPods product catalog. But I am an IT-man, damn you boy! So I want to buy it to play with it, to program with it!

    At last Bing is not so bad

    I have used Google in the past 8 years (I know, I am a bit old). Then I was annoyed because of a bad behavior of Google with my AdSense account (shutdown without being able to talk back to someone for explanation).

    Oracle Invalid number ORA-01722

    I stumbled upon a very brain-f**k error on Oracle 10g on these days.

    Context: the following query [sql]SELECT * FROM (
    SELECT TO_NUMBER(CUSTOMER_ID) AS SNDG FROM BAD_CODES_TABLE WHERE
    AND I_LIKE=UPPER(‘STATIC_CONDITION’) AND CUSTOMER_ID NOT LIKE ‘%P%’ ) S WHERE TO_NUMBER(S.SNDG) >2000[/sql] could trigger a Invalid number if CUSTOMER_ID column contains invalid numbers.

    Why?

    Well鈥f you ask to “explain plan”, you will get something like

    • a table full scan
      • Filter Predicates AND
        • I_LIKE=UPPER('STATIC_CONDITION')
        • TO_NUMBER(S.SNDG) >2000
        • CUSTOMER_ID NOT LIKE '%P%'
